Description

TECHNICAL FIELD OF THE INVENTION
The present invention relates to a dew condensation collecting device in a greenhouse that collects dew water adhering to the inner surface of a transparent or translucent synthetic resin sheet spread on a skeleton such as an arch pipe or rainwater invading from a broken point or the like.
[0001]
[Prior art]
Generally, in a greenhouse, a greenhouse in which a transparent vinyl sheet is spread on a framework such as an arch pipe, the room temperature and humidity in the house are higher than the atmosphere outside the house, and water is given to the crops and the water evaporates. A large amount of condensation adheres to the inner surface of the sheet on the indoor side. If this condensation is left untreated, it will flow down the inner surface of the vinyl sheet and if it reaches a certain weight, it will fall on the soil, not only discomforting workers working indoors, but also cause root rot and disease of the crop, It has a great negative effect on plant growth.
[0002]
Therefore, in order to solve this problem, for example, a dew condensation recovery device disclosed in Japanese Utility Model Publication No. 2-12863 has been developed, and has contributed much to the greenhouse industry.
[0003]
This dew condensation collecting device for a greenhouse has, for example, a structure shown in FIG. That is, this dew condensation recovery device includes the joint 50 and the sheet stoppers 2 fitted on the left and right sides of the joint 50.
[0004]
In this case, the sheet stopper 2 has a dovetail-shaped sheet stopper 3 extending along the longitudinal direction and a plate-shaped dew receiving portion 4, and a groove frame 7 which stands up while being bent upward in the middle. Is formed. On the other hand, the joint 50 includes a main body 51, a first insertion groove 55 for a sheet stopper groove provided on the upper surface side of the main body 51, a second insertion groove 56 for the dew condensation receiving portion, and a A guide frame 52, 53 for regulating the first and second insertion grooves 55, 56, and a groove formed in the middle of the first and second insertion grooves 55, 56 so as to cross in the front-rear direction and to face downward. And a drainage nozzle 58 which is vertically provided on the lower surface of the main body 51 and connected to the water collection port.
[0005]
Thereby, the sheet stoppers 2 are fitted from both sides of the joint 50, and these sheet stoppers 2 and the joint 50 are connected on the arch-shaped pipe. Through which the vinyl sheet is settled, whereby the vinyl sheet is spread on the arched pipe. In such a greenhouse, even if dew adheres to the inner surface of the vinyl sheet on the indoor side during use, the dew falls down the inner surface of the vinyl sheet and hits the dew receiving groove 4, where it collects. The water flows out into the water collecting port 57 through the drain 4 and is collected from the drain nozzle 58 and a hose connected to the drain nozzle 58 outside the house or on a gutter on the house.
[0006]
[Problems to be solved by the invention]
In the above-mentioned conventional dew collecting device, although there is no particular problem in function, it is desired to improve the following problems.
[0007]
Firstly, most of the condensed water flowing down from the dew receiving portion 4 is collected in the water collecting port 57, but a part thereof leaks from one or both sides of the joint 50 through the first and second insertion grooves 55 and 56. May fall into the house. Therefore, in order to prevent this, seal members 60, 60 are applied in advance to the upper surface of the main body 51 of the joint 50, and the space between the joint 50 and the sheet stopper 2 is sealed to prevent leakage of dew water. However, the application of the sealing material 60 is troublesome, the material cost is increased, and the assembling property and economic efficiency are poor. Also, at the time of disassembly or conversion of parts, the sheet stopper 2 must be peeled off from the seal member 60, and the work is troublesome.
[0008]
Second, the dew condensation phenomenon occurs not only on the inner surface of the sheet but also on the back of the sheet stopper 2 itself, and the dew attached to the back of the sheet stopper 2 travels along the back of the sheet stopper 2 and strikes the joint 50. In this case, there is a risk of falling into the house at this position, and there is no means for collecting this.
[0009]
Thirdly, since the end of the sheet stopper 2 is stopped at the inlet of the water collecting port 57 so that the condensed water in the condensation receiving groove 4 is stored in the water collecting port 57, the water collecting ports of the guide rails 52 and 53 are also provided. Since the end P on the 57 side is cut, a step is generated above the water collecting port 57, which may be an edge and damage the sheet.
[0010]
Fourth, trash accumulates in the water collecting port 57 during use for a long time, blue mold is generated, and in some cases, insects may invade and the flow of dew condensation water may be deteriorated. There is no way to collect these debris and the like, and to remove them, the whole must be disassembled.
[0011]
Fifth, the drain nozzle 58 is provided vertically downward from the joint main body 51. When a diagonal or horizontal hose provided along the roof surface of the greenhouse is connected to the drain nozzle 58, the connection portion of the hose is bent and the drainage nozzle 58 is used. The hose may be damaged and cut. Also, since the drain nozzle 58 is vertical downward, the hose may come off due to weight, vibration, or the like.
[0012]
Therefore, an object of the present invention is to always collect the dew water flowing from the sheet side or the sheet stopper material side without applying the sealing material, and to prevent the occurrence of a step to prevent the sheet from being damaged, and An object of the present invention is to provide a dew condensation collecting device in a greenhouse that can easily collect dust and the like accumulated in a water mouth from the outside and prevent the hose from coming off or being damaged.
[0013]

In a dew collecting device in a greenhouse having a water collecting port provided to face and a drain nozzle connected to the water collecting port, a pair of left and right gutter grooves and a front gutter groove communicating with both sides of the main body and the front side are formed. The first and second insertion grooves are respectively connected to the gutter grooves on both sides, and the water collecting port is connected to the front gutter groove.
[0014]
In this case, the pair of left and right gutter grooves and the front gutter groove are composed of a frame having an L-shaped cross section integrally connected to both sides of the main body and the front side, and upper ends of the frames on both sides are the first and second frames. It is preferable to be formed lower than the bottom of the insertion groove.
[0015]
Similarly, it is preferable that a drainage nozzle communicating with the front gutter groove is provided in the front frame in the horizontal direction, and a hole that opens to the water collecting port is provided in the upper rear part of the main body.
[0016]

[0022]
Next, the configuration of the dew collection device A will be described in detail.
[0023]
As shown in FIG. 1, this comprises a joint 1 and sheet stoppers 2 and 2 fitted on both sides of the joint 1. The sheet stopper 2 has a sheet retaining groove 3 and a dew-condensation receiving part 4. ing. The joint 1 includes a main body 10, a first insertion groove 5 for a sheet retaining groove provided on the upper side of the main body 10, a second insertion groove 6 for a dew condensation receiving portion, and a first and a second difference groove. A water collecting port 7 traversing in the front-rear direction and extending downward in the middle of the inlet grooves 5 and 6, and a drain nozzle 8 connected to the water collecting port 7.
[0024]
Further, as shown in FIGS. 1 and 3 to 6, the joint 1 is provided with a pair of left and right gutter grooves 9 a and 9 b and a front gutter groove 9 c communicating with each other on the left and right sides and the front side of the main body 10. The openings on both sides of the first and second insertion grooves 5 and 6 are directly connected to the grooves 9a and 9b, respectively, and the water collecting port 7 is connected to the front gutter groove 9c.
[0025]
In this case, the pair of left and right gutter grooves 9a and 9b and the front gutter groove 9c are composed of frames 11, 12, and 13 having an L-shaped cross section integrally connected to both sides of the main body 10 and the front side. The upper ends a, b of the frames 11, 12 are formed lower than the bottom surfaces 5a, 6a of the first and second insertion grooves 5, 6.
[0026]
Further, a flow guide 26 is integrally provided downward on the front frame 13, and a drain nozzle 8 communicating with the water collecting port 7 and the front gutter groove 9c is provided at the outer end of the flow guide 26 in the horizontal direction. In addition, a hole 14 opening to the water collecting port 7 is provided in the upper rear part of the main body 10.
[0027]
Further, guide frames 15 and 16 for regulating the first and second insertion grooves 5 and 6 so as to partition the first and second insertion grooves 5 and 6 are provided on the upper surface of the main body 10 along the longitudinal direction. On the other hand, the sheet stoppers 2, 2 are formed with slightly U-shaped groove frames 17, 17 to be fitted to the guide frames 15, 16. A stopper 27 is erected at a position corresponding to the water collecting port 7 on the guide frames 15 and 16, and the ends of the sheet stoppers 2, 2 inserted from both sides into contact with the stopper 27 are brought into contact with the stoppers 2. , 2 are restricted.
[0028]
A hose 20 is inserted into the drain nozzle 8, and the hose 20 extends along the arch pipe 22 toward the gutter 23 or outside the house. The hose 20 may be inserted into the discharge nozzle 8 as shown in FIGS. 6 and 7, but it is preferable to connect them together by a method as shown in FIG. That is, a plurality of ribs 18 are formed on the outer periphery of the drain nozzle 8 along the circumferential direction, and a hose 20 inserted into the drain nozzle 8 is formed of a hard material having a continuous annular groove 19. The hose 20 is connected to the drain nozzle 8 by one-touch by fitting.
[0029]
The hose 20 shown in FIGS. 6 and 7 has a distal end 20a formed in a cylindrical shape. When the distal end 20a is inserted into the drain nozzle 8, it does not come off due to friction of the outer peripheral rib 8a of the drain nozzle 8, and if necessary. Both are fastened via a wedge member. Of course, such use is also possible, but if the tip 20a of the hose 20 is damaged, it is difficult to reuse it and it is necessary to replace a new hose. In this case, it is necessary to replace the hose with a cylindrical tip. Need to be replaced.
[0030]
However, in the case of the structure of the hose 20 as shown in FIG. 8, since the structure of the tip is not restricted, the hose 20 itself may be cut at an arbitrary position and fitted directly to the drain nozzle 8 side. If a long hose is prepared in advance, the hose can be arbitrarily cut and used even when replacing it with a new hose.
[0031]
Next, the operation when collecting dew will be described.
[0032]
As described with reference to FIG. 2, the dew K attached to the inner surface of the sheet S flows as water in the direction of the joint 1 via the dew receiving portion 4, and the water flows into the water collecting port 7 in the joint 1, and further drains. It is discharged to the outside through 8 and the hose 20. At this time, some water may leak through the gap between the lower surfaces of the sheet stoppers 2 and 2 and the upper surface of the main body 10 of the joint 1 without flowing to the water collecting port 7. Is collected in the left and right gutter grooves 9a and 9b and further discharged to the hose 20 side through the front gutter groove 9c, so that water can be prevented from falling into the house from both sides of the joint 1.
[0033]
Further, dew may adhere not only to the inner surface of the sheet S but also to the bottom surface of the sheet stopper 2 itself, and this may flow as dew water to the joint 1 side. However, even in this case, as shown in FIG. Since the upper surfaces a, b of the frames 11, 12 on both sides for regulating 9 b are lower than the upper surface of the main body 10, a gap is formed between the frames 11, 12 and the sheet stoppers 2, 2. The condensed water flowing down the lower surface of the device does not interfere with the frames 11 and 12, flows through the gap to the main body 10, falls when hitting the main body 10, and is collected in the gutter grooves 9a and 9b. For this reason, it is possible to prevent the condensed water from falling into the house when the condensed water flies from the sheet stopper 2.
[0034]
Since the hole 14 communicating with the water collecting port 7 is located above the main body, water does not flow out from the hole 14. This hole 14 is used to insert a stick or a jig from the outside to remove the dust and the like when dust, mold, or insects enter the water collecting port 7.
[0035]
The stopper 27 regulates the fitting stroke of the sheet stopper 2, which is located above the water collecting port 7, and makes the height level of the groove frames 17, 17 in the sheet stoppers 2, 2 on both sides uniform. Therefore, it is possible to prevent the sheet S from being caught on the edges of the guide frames 15 and 16 and damaged.
[0036]
