DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The construction common to all claims will be described. The basins C are, as described above, a meeting place basin, a drainage basin, a sewage basin, and other well-known basins disposed at an intersection or an intermediate portion of a drainage channel formed by a U-shaped groove, a drainage pipe, or the like. The grating G is a well-known lattice-shaped or sashimi-shaped water-permeable plate disposed at the opening of the box C. The security chain P for grating is a well-known security member that prevents a vehicle from being jumped even if it passes over the grating G, and prevents the grating G from being stolen.
One end is fixed to the box C, and the other end is connected to the grating G by the connecting ring 4. The security chain P for grating is used by the owner or the manager of this kind of drainage facility to make
It is a fact that the fixing site of the security chain P is different from that of the grating G, and the length of the security chain P varies depending on the owner or the manager. For this reason, in order to arrange the strainer 1 in the boxes C, a device for arranging the strainer 1 so as not to interfere with the security chain P for grating is necessary. (This point will be described later.)

Next, claims 1 and 2 will be described with reference to FIGS. The strainer 1 is constituted by a permeable collection basket 1a, and the structure thereof is such that the collection basket is constituted by a wire net 1b and a frame 1c as in the first example shown in FIGS. Although not shown, it is conceivable to use a well-known punching metal (made of stainless steel) in which a myriad of through holes are regularly arranged. When the former garbage basket 1a is composed of the wire mesh 1b and the frame 1c, the wire mesh 1b (made of stainless steel) is attached to the frame 1c (square in the illustrated example) composed of a hard metal wire (thick stainless steel wire). The garbage basket 1 is stretched and the wire mesh forms the side wall and the bottom.
a, a frame 1d (stainless steel plate) is provided at the opening of the garbage basket, and a structure required for hanging the strainer 1 and a structure required for overflow drainage are provided in the frame (these structures will be described later). ) To constitute the strainer 1.

When the garbage basket 1a is composed of the wire netting 1b and the frame 1c, the shape of the frame 1c is not limited to a substantially square shape in plan view as shown in FIGS. It can be considered to be configured as a rhombus, a rectangle or the like, and as another shape, it can be considered to be configured as a circle such as a true circle, an oval, or an ellipse in a plan view. If the shape of the frame 1c is determined, A strainer 1 having the same shape as the shape is formed. When the garbage basket 1a is made of the punched metal, a rectangular shape in a plan view (square, rhombus,
It can be configured in a rectangular shape (rectangular shape) or a circular shape in a plan view (true circular shape, oval shape, elliptical shape, etc.). In this case, the shape of the through-holes in the punched metal, the number of arrangements of the through-holes, the same state, and the like may be variously used, and may be well-known.

Next, the structure for suspending the strainer 1 according to claims 1 and 2 shown in FIGS. 1 to 6 will be described with reference to FIG. One horizontal mounting hole 6 for mounting the tool 5 so that the horizontal position can be adjusted and the height position can be adjusted is respectively opened, and one horizontal drain hole 7 for performing overflow drainage in the remaining opposed portion is opened. I do. The hanging member 5 is formed of a metal plate (stainless steel plate) having an L-shaped cross-section, and a plurality of hanging holes 8 are formed in a vertical plate portion in a vertical line. Pass the mounting bolt 9 through the hole 6,
Further, a nut 10 is screwed and fastened to a bolt protruding end protruding from the horizontally long mounting hole 6, and the hanging tool 5 is connected to the mouth frame 1 of the strainer 1.

Then, the horizontal plate portion (a plate portion formed at right angles to the upper end portion of the vertical plate portion) of the hanging tool 5 is engaged with the lower horizontal plate portion of the Z-shaped mouth frame 11 of the box C, and the strainer 1 is moved. After being placed in the box C, the grating G is placed on the lower horizontal plate of the mouth frame 11, and the horizontal plate of the hanging tool 5 is sandwiched between the grating G and the mouth frame 11, so that the strainer 1 is connected to the box C. Hang it directly inside. (See FIGS. 1 and 2)

Next, a case where the strainer 1 is suspended in the cell C so as not to obstruct the security chain P will be described. As described above, the security chain P is different in the fixing portion with the basin C, the connecting portion with the grating G, and the like depending on the drainage facility owner or manager as described above, and the length of the chain itself is also different,
In order to suspend the strainer 1 in the basin C, it is necessary to prevent the strainer 1 from interfering with the security chain P. As a device for this purpose, in the present invention, as shown in FIG. The height can be adjusted so that the strainer 1 does not obstruct the security chain P, and the hanger 5 can be adjusted in the horizontal position as shown in FIG. It was configured so as not to disturb P. In order to adjust the height position of the strainer 1 or the hanging tool 5, after removing the nut 10 from the mounting bolt 9, the bolt is once removed from the horizontally long mounting hole 6 and the hanging hole 8, and the strainer 1

8, and screw the nut 10 again to the bolt protruding end protruding from the horizontally long mounting hole 6.
The height position is adjusted to be high or low, and the strainer is suspended in the box C without worrying that the strainer will interfere with the security chain P.

Since the hanging member 5 is sandwiched between the grating G and the frame 11, the height position of the hanging member 5 with respect to the security chain P cannot be changed. Therefore, if the hanging tool 5 interferes with the security chain P, the nut 10 screwed to the mounting bolt 9 is loosened, and the mounting bolt 9 is moved to a position where the hanging tool 5 does not interfere with the security chain P. Is horizontally moved while penetrating through the horizontally long mounting hole 6, and when the position of the bolt is determined, the nut 10 is re-tightened so that the lifting tool 5 does not interfere with the security chain P and the strainer 1 Can be hung inside. Next, the structure required for the overflow drainage of the strainer 1 is shown in FIGS.
Explaining with reference to FIG. 6, this structure is originally a garbage basket 1
The wastewater to be passed down through a is blocked by the dust collected and accumulated in the garbage basket 1a, and the basin C
Is provided in order to prevent the water from passing through the grating G and overflowing to the ground. The drainage holes 7 are formed by opening one horizontally long drainage hole 7 in each of the opposing portions of the mouth frame 1d, and are disposed in the garbage basket 1a. It is configured so that the waste above the accumulated dust, that is, the wastewater can flow down through the upper part of the garbage basket 1a by passing through the horizontally long drainage hole 7 so as to prevent the above-mentioned overflow to the ground. I do.

Here, the horizontal drain hole 7 can be constituted by a large number of independent drain holes. (See Fig. 6.) Garbage basket 1

Are trapped by the water-permeable trapping plate 1f. The structure of the water-permeable trapping plate 1f is not limited to the substantially comb shape shown in the illustrated example, but may be, for example, a well-known stainless steel punching metal or a wire mesh in which a same-size wire mesh is stretched on a stainless steel square frame. A body, a stainless steel lattice plate or the like may be formed into an L-shaped cross section and fixed to the lower surface of the hanging peripheral portion 1j of the garbage plate 1e. Permeability capture plate 1
f is configured so that the vertically permeable vertical plate portion can be formed long so as to be able to cross the drainage channel, so as to enhance the effect of capturing dust.

The water-permeable capturing plate 1f has a stainless steel wire mesh (not shown) stretched over a part of the front end (part of the lower end in FIGS. 7 to 10) of the water-permeable vertical plate shown. It is preferable to be configured so as to reliably capture fine dust. The permeable catch plate 1f shown in FIGS. 7 to 9 is an example in which only one permeable catch plate 1f is attached to the lower surface of the garbage plate 1e, but as shown in FIG. 1j may be fixedly provided one by one at the lower surface facing portion 1j. When disposing the strainer 1 of this example in the box C, the pair of water-permeable capturing plates 1f are arranged so as to be vertically suspended at the upstream part and the downstream part in the box C. The strainer 1 shown in FIG. 11 corresponds to claim 4 and is characterized in that a stainless steel garbage plate 1e is provided with a stainless steel permeable permeable catching plate 1g having an adjustable length, and the strainer 1 is constituted. And

The structure of the water-permeable trapping plate 1g whose length can be freely adjusted can be considered. However, two types of examples will be described. In the drawing, the trapping plate 1g on the right side is a vertical plate of an L-shaped cross-section substrate 1k. A plurality of vertically long holes (not shown) are formed in the hole, and the same number of holes (not shown) are formed in the water-permeable capture plate 1g. To nut (not shown)
Is screwed and the degree of tightening of the nut is adjusted so that the water-permeable capturing plate 1g can be slid, and the length can be adjusted by the sliding.
In FIG. 11, the left capturing plate 1g is formed by perforating a plurality (two in the illustrated example) of vertically long holes 1m in the water-permeable capturing plate 1f having an L-shaped cross section.
A similar number of holes 1m are drilled in the other water-permeable catching plate 1g in the same number, and a nut 1n is screwed into a tip of a bolt 1l penetrating the holes, and the degree of tightening of the nut is adjusted. , The permeable catch plate 1g can be slid, and the length can be adjusted by this structure.

As described above, the reason why the length of the water-permeable trapping plate 1g can be adjusted is as follows. After the strainer 1 is disposed in the box C, if the cross-sectional area of the trapping plate 1g with respect to the drainage channel is variable. This is to improve the capture rate of trash mixed in the wastewater. Claim 4 shown in FIG.
As described above, the strainer 1 is configured by providing the garbage plate 1e with the water-permeable capturing plate 1g whose length is adjustable, and the number of the capturing plates is one pair as shown in the illustrated example. It is not limited to this, and only the right side structure or the left side structure may be used in the same figure.

When the strainer 1 according to claim 4 is arranged in the box C, if the permeable catch plate 1g is only one of the right and left structures shown in FIG. If the catch plate is provided on the downstream side in the box C and a pair of the catch plates is provided, it is suspended on the upstream side and the downstream side in the box C. When the strainer 1 is placed in the box C, the garbage plate 1e is sandwiched between the gray tink G and the Z-shaped mouth frame 11 of the box C in the same manner as in the first to third embodiments. is there. Further, the water-permeable trapping plate 1g can be configured in various structures as in the case of the trapping plate of the third aspect .

Next, claims 5 to 10 will be described with reference to FIGS. 12 to 16, and the same configurations as those in claims 1 to 4 will not be described repeatedly, and different configurations will be described. The suspension rod 2 has a locking piece 2a formed at one end (upper end in the figure) of one side of an L-shaped angle in a plan view at a right angle, and a large number of engagement holes 2b are formed in a row in the longitudinal direction of both sides of the angle. And 4
Use as a set. The receiving member 3 is also formed by piercing and arranging a large number of through holes 3a in the longitudinal direction of one side or both sides of the L-shaped angle similar to the hanging rod 2. When the hanging rod 2 and the receiving member 3 are used by suspending them in the box C, in order to use the strainer 1 with good stability, one set of hanging rods 2 is used before the hanging rod 2 is suspended in the box C. The opposing sides of the rods 2 are connected by long bolt rods 13 and nuts 14, respectively, and the remaining opposing sides not connected by the bolt rods and nuts are connected by receiving members 3 to assemble them so that they can be suspended. The bolt rod 13 used for this assembly penetrates into the engaging hole 2b. (See FIG. 13)

A short bolt 15 and a nut 16 are used to connect the hanging rod 2 with the receiving member 3. The bolt is inserted through the engaging hole 2b and the through hole 3a, and the nut 16 is screwed into the receiving hole. The fixture 3 is erected and connected between the adjacent suspension rods 2. When one set of the hanging rods 2 is assembled in this way, as shown in FIG.
Is placed on the lower horizontal plate portion of the Z-shaped mouth frame 11 of the box C, the grating G is placed on the locking piece 2a, and one set of the hanging rods 2 is suspended in the box C, and then the strainer The strainer 1 is placed on the receiving member 3, and the strainer is indirectly suspended in the cell C by the hanging rod 2 and the receiving member 3. When it is desired to change or correct the arrangement position of the strainer 1 suspended in the basin C, the strainer is temporarily lowered from the support 3, and then the bolt 15 and the nut 16 are removed from the suspension rod 2 and the support 3. ,
By using another engaging hole 2b and a through hole 3a having different height positions from the previous time, the bolts and nuts are provided with the receiving members 3 at different height positions of the adjacent hanging rods 2 from the previous time. Concatenate. Then, the strainer 1 is mounted again on the holder 3 changed or corrected to the proper arrangement position, and the strainer is arranged at the appropriate arrangement position.

The strainer 1 is not limited to one in number as shown in FIGS. 12 and 13, but is shown in FIG.
As shown in FIG. 15, a plurality of small strainers can be configured and arranged on the receiving member 3. The purpose of using the small strainer 1 in this way is to use a small strainer with a small or medium capacity because it is not easy to easily take out the large strainer 1 on which a large amount of trash is accumulated from the boxes C. Accordingly, it is possible to easily perform a strainer removal operation, a dust removal operation from the strainer, and the like. When a plurality of small strainers 1 are used as described above, ones having the same capacity as shown in FIG. 14 or those having different capacities as shown in FIG. 15 can be used.

In the case of using the latter small strainer 1 having a different capacity, the strainer having a small capacity (the strainer on the right side in the figure) is replaced by another strainer 1 (for example, a strainer having a medium capacity; the strainer on the left side in the figure). Therefore, it is inconvenient to use a single long receiving member 3 for mounting both strainers. Therefore, a plurality of receiving members 3 having different lengths ( specifically, one each as shown in FIG. 15)
Each of the strainers 1 is used for a strainer, and the strainers 1 having a capacity corresponding to the length of the strainer are placed on the plurality of the receivers 3 respectively. In this mounting method, as shown in FIG. 15, a small-capacity strainer 1 is mounted on a short receiver 3, and another strainer (for example, a medium-capacity strainer) is mounted on a long receiver 3. Thus, a plurality of strainers 1 of different capacities
The purpose of using is the same as the purpose of using a plurality of the equal capacity strainers. When using a plurality of equal capacity strainers 1 or different capacity strainers 1 described above, FIG.
It is safe to use the intermediate suspension rod 17 as shown in FIG.

The intermediate suspension rod 17 is formed to have the same length as the suspension rod 2 and is formed to have a wide width capable of forming two rows of engagement holes 17b. Stop 17
a is formed by projecting at a right angle. When a plurality of the equal-capacity strainers 1 are placed on the receiving member 3, a contact portion between the strainers is formed. However, a concentrated load may be applied to the receiving member 3 by the contact portion. The lengthwise intermediate portion of one long receiver 3 is attached to the intermediate suspension rod 17 with short bolts 15 and nuts 16 so that a plurality of strainers 1 can be stably mounted.

In addition, a plurality of different capacity strainers 1
In this case, a short length of the receiving device 3 corresponding to the small strainer 1 is used. Therefore, a plurality of receiving devices 3 having different lengths must be used with different heights. Therefore, as shown in FIG. 15, the intermediate suspension rod 17 must be used, and one end of each of the plurality of receiving members 3 having different lengths must be fixed to the intermediate suspension rod 17 by bolts and nuts to stabilize the plurality of different capacity strainers 1. It is placed on the receiving device 3 with good efficiency. In the case where one strainer 1 is used, the receiving member 3 can be composed of the same number of small pieces as the hanging rod 2. (See FIG. 16)
It has an L-shape when viewed from the front, and has a through hole 3 on one or both sides.
Then, the receiving member 3 is attached to the hanging rod 2 with the short bolts 15 and the nuts 16 using the through holes.

Since the fifth to tenth aspects are configured as described above, the height arrangement position of the strainer 1 can be freely adjusted, and the dust trapping device is convenient for use. Incidentally, the material in the above-described embodiments of all the claims is not limited to stainless steel, and is not limited to FRP, other synthetic resins not subjected to drainage, and metals other than stainless steel (for example, Materials such as enameled iron plate, color iron plate, cast iron, and galvanized plate can be used.
The arrangement of the hanging rod 2 according to claim 5 is not limited to the arrangement in which a virtual rectangle is formed in plan view as shown in FIGS. It is possible to adopt an arrangement mode according to the cross-sectional shape of the box C, for example, by arranging so as to form a square.

[0024]

According to the present invention, the hanging was whether <br/> et al. So as not to interfere with the gray <br/> Chingu for the security chain the strainer as on the ordination, is worried that the strainer is damaged by the security chain To eliminate. Further, since the strainer is configured without using the waste basket, the configuration of the strainer can be performed efficiently, and the work of removing dust from the strainer can be performed efficiently and easily. Furthermore, the height position of the strainer can be freely adjusted by using the hanging rod and the receiving device, which is not only convenient to use but also can change the height position of the strainer according to the height positional relationship between the basin and the drainage channel. If the strainers with the same or different capacities can be used, it is possible to use the strainers with the same or different capacities. There is an advantage that a kind removing operation can be easily performed.
