Description

[Detailed description of the invention] This invention relates to a water supply and drainage device for the purpose of supplying or draining water between an irrigation canal and a rice field, or between an irrigation canal and a fish tank or fish pond, etc. by adjusting the amount of water as appropriate. It is something.

In general, this type of irrigation canal and water supply and drainage canals used between rice fields or between rice fields, fish ponds, fish tanks, etc. are made of concrete or wood, but in this case, a large amount of construction work is required. The drawbacks are that it takes a lot of time and effort, and is very expensive.In addition, it is very troublesome to install and adjust the partition plates that adjust the amount of water passing through the water supply and drainage channels, and it is difficult to store unused partition plates. There were disadvantages such as there was no place to store them and they could get lost or damaged. Further, conventional devices have the disadvantage that they are easily damaged and cannot be easily repaired or replaced after damage.

This invention improves on each of these conventional drawbacks; it allows pre-produced water supply and drainage equipment to be easily installed at the location of use, makes the whole system stronger, and allows various adjustments to be made to the amount of water supply and drainage. It is something. In addition, several unused partition plates can be stored inside the water supply and drainage main body to reliably prevent them from being lost. The main structure of this invention is that the water supply and drainage main body has left and right side walls, and an upper support frame and a lower support frame are horizontally disposed on the front and back sides of the side walls to form a box-like body. Moreover, on the surface of this water supply and drainage main body, partition grooves are formed facing each other in which several partition plates can be attached and detached in a vertically movable manner. Further, in the upper ceiling portion of the water supply and drainage main body, storage grooves in which the partition plates are slidably stored in a detachable manner are formed so as to face each other. As mentioned above, according to this invention, it can be freely used for irrigation water edges, ridges, fish ponds, etc., and by using or storing several partition plates as needed, the amount of water passing through can be reduced. This has the effect of being able to freely adjust the

Next, an embodiment of this invention will be described in detail with reference to the drawings. The water supply and drainage main body 1 is made of synthetic resin, and has left and right side walls 2, 2, etc. having a rectangular shape facing each other upright. On the opposing side walls 2, 2, an upper support frame 3, a lower support frame 4, an upper support frame 5, and a lower support frame 6 are horizontally installed on the front side and the back side, respectively, so that the whole is box-shaped. It has been configured. In addition, several partition plates 1 are placed on the surface of the water supply and drainage main body 1.
1, 11, . . . are formed in vertical protrusions 8, 8 arranged in parallel on the inside of the side walls 2, 2. Further, in the upper ceiling of the water supply and drainage main body 1, a storage groove 10 in which the partition plates 11, 11 can be slidably attached and detached is formed by horizontal protrusions 9, 9 arranged in parallel on the inner side of the side walls 2, 2. It is mandatory. Next, the constituent material of the partition plate 11 is a synthetic resin board or a wooden board, and notches are provided on both sides in the longitudinal direction so as to close the gap when the partition plates 11, 11 are installed. Step portions 12, 12 are formed respectively. Reference numeral 13 indicates side walls 2, 2 of the water supply and drainage main body 1.
The leg portions 13, 13 make it easy to enter the underground 17.
Reference numeral 15 indicates a paddy field divided by ridges 14, 14, and reference numeral 16 indicates an irrigation canal.

This device has the above-mentioned configuration, and its usage is explained as follows:
4, 14, and a predetermined position such as a roadside path of a fish pond etc., the water supply and drainage main body 1 is installed in a buried state with the legs 13, 13 facing down as shown in FIG. Next, several partition plates 11,
11... are used as shown in Figure 5 A, B, C, etc.
That is, the case of Figure A shows the case where several partition plates 11, 11 are fitted into the partition grooves 7, 7 and the water gate is fully closed. In the case of Figure B, the one partition plate 11 shown in Figure A is pulled upwards and partially opened to make the water gate half open. In this case, the removed partition plate 11 is , upper storage groove 1
0 and 10. Next, in the case of Figure C, all the partition plates 11 are removed from the partition grooves 7, 7 to fully open the water gate and increase the amount of water supply and drainage. ,11
... are inserted and stored in the upper storage grooves 10, 10.

As described above, this invention has the advantage of being able to freely adjust the flow rate of water supply and drainage to irrigation canals, paddy fields, fishponds, etc., and that the installation and construction of the main body of the water supply and drainage is much easier than with conventional methods. effective.
By forming the water supply and drainage main body into a box-like structure including the left and right side walls and the upper and lower support frames on the front and back sides, the entire body can be made extremely strong and lightweight. By making the whole thing made of synthetic resin,
There are no concerns such as corrosion. In addition, the partition grooves formed opposite each other allow the partition plate provided on the surface of the water supply and drainage main body to be attached and removed freely up and down, making it extremely easy to add and remove the partition plates, and therefore increase and decrease the water supply and drainage flow rate accurately and quickly. There is a practical effect that it can be done. Furthermore, due to the storage grooves formed opposite to each other on the ceiling of the water supply and drainage main unit, the partition plates that are pulled out when adjusting the water volume can be stored in the upper storage groove in sequence, which is very convenient and also prevents them from getting damaged or lost. It has such practical effects that there are no worries, and the excellent effect that it can be easily taken out and used as a partition plate when in use.
