Description

DETAILED DESCRIPTION OF THE INVENTION The present invention covers the entire upper surface of waterways in open waterways, sewage water, irrigation waterways, etc. so that the odor generated from the water flowing in the waterway does not migrate to the outside, and when necessary, it can be moved. This invention relates to an improvement of a movable deodorizing plate that can open the waterway surface.

Recently, waterways and sewage purification equipment at water pumping stations and sewage treatment plants have been increasingly housed indoors in underground structures to prevent odors and noise from emitting outside, but this has caused problems in the working environment and hygiene. It is necessary to eliminate the odor generated from sewage so that it does not get stuck in the room, but ventilating the entire room will increase the equipment cost of ventilation equipment and the operating cost. The top surface of the open channel is covered with a deodorizing board to prevent odors from escaping. There are two types of deodorizing plates: fixed type and movable type, and depending on the length of the open channel, limited opening/closing type and fully opening/closing type are used. However, in the case of a settling basin installed at the entrance of a waterway, during raking of the bottom of the pond or collection of mud, the raking member or the collecting pipe is inserted into the water of the waterway from the scraper or mud collector that runs back and forth on the upper part of the waterway. Since the odor-proofing board is suspended, it gets in the way, so if it is a fixed type, it is necessary to cover or remove the odor-proofing board, which takes time and effort. It is impossible to completely prevent this, and movable deodorizing plates that can be opened and closed completely have a disadvantage of having a complicated structure and being prone to failure.

In order to reduce the manufacturing cost and operation time of the deodorizing plate, the present invention always covers the upper surface of the waterway airtightly to block the odor generated from the running water, and when necessary, it automatically moves from the waterway surface to prevent the water from flowing. To provide a completely open/close type movable deodorizing plate that can open the road surface and automatically cover the water surface again in an airtight manner when no longer needed, and is less prone to failure.

The movable deodorizing plate of the present invention has a band-like deodorizing plate in which a large number of rectangular plate members each having a length approximately equal to the width of a waterway are connected by pivoting members at both ends of each rectangular plate member in order so as to be foldable. comprising a plate, rotatably attaching a hanging member having an upper roller to every other pivot member, and attaching a lower roller to every other plate member in the vicinity of the other pivot member;
The band-shaped deodorizing plate is unfolded and movably supported by an upper roller, a lower roller, an upper guide rail, and a lower guide rail, respectively, so as to cover the waterway, and the folded band-shaped deodorizing plate is accommodated at the starting end of the waterway. A lifting portion is formed on the upper guide rail so that the belt-shaped deodorizing plate can be opened and closed by a drive device.

and upper rollers 19 so that their respective ends are alternately carried by the lower guide rail C ₂ and the upper guide rail C ₁ . In addition, at the front edge of each plate member B ₁ , B ₂ , B _{3 .} . . B A sealing plate 20 made of a soft material is fixed with a presser plate 21 to cover and maintain an airtight state. Reference numeral 22 designates a pivot shaft 1 so that when the band-shaped deodorizing plate is folded, each adjacent plate member is accommodated with an appropriate gap.
This is a stopper to prevent 0, 13, etc. from being damaged. The guide rails C ₁ and C ₂ are formed in the form of a channel with upper and lower layers stacked horizontally, but the upper guide rail C ₁ is curved upward smoothly near the start of the inflow of the waterway and raised to become horizontal. A lifting portion is formed so that when the band-shaped deodorizing plate is folded, the plate members B ₁ , B ₂ , B ₃ . . . B _x can be housed vertically between the upper and lower guide rails C ₁ and C ₂ . It's getting old. Attachments 5 are attached to the roller shafts 15 on both sides of the plate member B ₁ at the final end of the belt-shaped deodorizing plate B.
One end is loosely fitted, and the other end is pivotally connected to each link 31 of the chain D on both sides by a stop bolt 30, and when the chain D is run toward the outflow end of the waterway A, the attachment 5
The strip-shaped deodorizing plate B is stretched to cover the waterway surface, and on the other hand, when the chain D is run toward the inflow starting end of the waterway A, the strip-shaped deodorizing plate B is pushed back via the attachment 5. , roller 16,1
9 and guide rails C ₁ and C ₂ , the plate members B _x are sequentially folded and stored as shown in FIGS. 3 to 6, and the upper surface of the waterway is opened.

Next, the sealing structure for the gap between the wall surface of the waterway A and the strip-shaped deodorizing plate B will be described. On the waterway inflow side, as shown in FIG. When the band-shaped deodorizing plate B is horizontally deployed on the partition plate 24 which is set up from the end of the plate member B _x , the sealing plate 25 made of a soft material attached to the edge of the plate member B As shown in FIG. 8, the seal plate 27 made of a soft material is attached to the partition plate 26 vertically lowered from the waterway structure, and the strip-shaped deodorizing plate B is expanded horizontally. Plate member B ₁ is the seal plate 27
When the seal plate 27 comes directly under the plate member B1, the seal plate 27 comes into contact with the upper surface of the plate member _B1 , so that this part can be held airtight. Furthermore, as shown in FIG. 9, the side of the waterway A has a sealing plate 28 installed from the upper surface of the upper guide rail _C1 that is airtightly connected to the side wall surface of the waterway.
A sealing member 29 made of a soft material is secured to the tip of the band-shaped deodorizing plate B with a fixing bolt 30, so that when the band-shaped deodorizing plate B moves along the waterway, the upper surface of the band-shaped deodorizing plate B is attached to the sealing member 2.
It slides in contact with the lower end surface of 9 and holds this part airtight.

Since the present invention is configured as described above, the belt-shaped deodorizing plate B is always deployed horizontally on the upper surface of the settling basin waterway A to block odor generated from running water, but the odor generated from the flowing water is prevented from being deposited at the bottom of the waterway A. When using a scraper or a sludge collector to remove sludge, the drive device E is activated to rotate the chain gear 1 clockwise to move the chain D toward the inflow side of the waterway. , the plate member _B1 is pushed back toward the waterway inflow side via the attachment 5 pivotally attached to the link 31 of the chain D, but at this time, the lower roller 16 fitted into the roller shaft 15 is pushed back to the lower guide rail.
The upper roller 19 inserted into the roller shaft 18 by C ₂ is guided by the upper guide rail C ₁ and pushes back the adjacent lid members B ₂ , B ₃ . . . B _x via the pivot shafts 10 and 13. The starting end of the plate member B _x is moved as a whole toward the inflow side until it reaches the lifting part of the upper guide rail C ₁ and the lower roller 1 is moved as a whole toward the inflow side.
6, it is guided to the lower guide rail _C2 and moves horizontally, and the other end is guided to the lifting part of the upper guide rail _C1 by the upper roller 19 and lifted upward, but the next adjacent plate member is pivoted. Since it is pivotally connected by the shaft 10, the plate member B _x
In the same way, the belt-shaped deodorizing board moves forward while being vertically folded and lifted, and by continuing the above operation, the strip-shaped deodorizing board is applied to the board members one after another.
The whole is folded into the inflow end of the waterway A, and the necessary part of the waterway A is opened, so a raking member or a sludge collecting pipe (not shown) is inserted into the waterway to perform raking and sludge collection work. It is possible. Next, if you want to cover the upper surface of waterway A after completing the raking work or mud collection work, reverse the driving device E and rotate the chain gear 1 counterclockwise to move the chain D in the opposite direction. When running, the plate member _B1 , which is pivotally connected to the chain D, is pulled toward the outflow side of the waterway A, and the adjacent plate members _B2 , _B3 ... _Bx are sequentially stretched and gradually return to the horizontal state. . At this time, plate members B ₁ , B ₂
...Both sides of the surface of B _x slide while contacting the sealing member 29, and each plate member B ₁ , B ₂ ...The sealing plate 20 attached to B _x alternately contacts the sealing member 29.
B ₁ , B ₂ . . . contact the contact portions of B _x from above or below, thereby maintaining the airtight state of these portions. Furthermore, when the belt-shaped deodorizing plate is fully extended, the upper surface of the plate member B ₁ comes into contact with the sealing member 27 and blocks the space between the end of the belt-shaped deodorizing plate B and the waterway A. The entire upper surface of the tank is airtightly covered with a band-shaped deodorizing plate, so odors generated from running water do not migrate to the outside. Of course, the above-mentioned operations may be linked with the operations of the scraper and the sludge collector so that the entire operation is automated.

As is clear from the above description, the present invention constitutes a foldable band-shaped deodorizing plate by pivotally connecting the respective ends of a large number of rectangular plate members, and also comprises a foldable band-shaped deodorizing plate attached to each end of the plate member. It is a fully openable and foldable movable deodorizing plate that guides the rollers using two upper and lower guide rails and is foldable, so the structure is lightweight and simple, easy to manufacture, less likely to break down, highly durable, and easy to operate. It has many advantages such as low operating costs.
