Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a sifion type water intake device for an agricultural pond, which utilizes the principle of the sifon and has a simple structure to take water from the agricultural basin (11).

[0002]

[Prior art]

 Conventionally, water is taken from the agricultural pond (11) by using wooden gutters (13), bottom gutters (14) provided on the bank (12), and wooden plugs inserted into holes at regular intervals in the gutters (14). It was composed of 15) and a facility where people entered the agricultural pond (11) and pulled out the wooden plug (15) to take water. Such a conventional method is very dangerous because a person directly enters the pond and works.

[0003]

[Problems to be solved by the device]

 In the conventional method, in order to increase the water intake capacity, it is necessary to remove the wooden plug (15) at a deeper position and take water, but in order to use it in paddy fields, it is necessary to take water with a high surface water temperature. There is a limit to the water depth due to the fact that people work directly in the pond.

In addition, it is necessary to constantly monitor the agricultural water pond (11) and perform the above work each time the water level drops. On the other hand, if the amount of water storage increased due to rainfall or the like and flooding occurred, it was necessary to close the wooden plug (15). This work must be done in the rain and without time loss, and the contents of water intake work are extremely dangerous.

In addition, the above-mentioned work is becoming more and more dangerous and difficult due to the time limitation due to the aging of agricultural workers and the increase in the number of part-time farmers.

The present invention eliminates the need for a person to enter the agricultural water pond (11) and pull out the wooden plug (15) to take out water, and eliminates the risk of the work, so the principle of the sifon is adopted. It aims to provide a device that can take water safely and use surface water.

[0007]

[Means for Solving the Problems]

 The sifion type water intake device according to the present invention has been devised by solving the problems in view of the above circumstances. The sifion type water intake device according to the present invention is installed in an agricultural basin, connects the agricultural basin with a headrace, and uses the sifon principle to ensure safe and effective water intake.

It is preferable that the siphon tube (1a) has flexibility, is excellent in weather resistance and water resistance, and can sufficiently withstand negative pressure.

The float (4) is preferably excellent in weather resistance and water resistance, and has a stable structure and arrangement.

Further, the structure may be such that water can be taken in and water can be stopped by remote control.

In addition, a structure may be adopted in which water can be taken in and stopped in accordance with changes in the water level of the agricultural pond by automatic control.

[0012]

[Action]

 The siphon-on type water intake device of the present invention enables surface water intake in response to a change in the water level of the agricultural water pond (11) by the siphon-on pipe suction part (6) held by the float (4), and the agricultural water pond (11) ) Is connected to the headrace (16) by utilizing the principle of Saifuon, which is a Saifuon intake system for agricultural ponds.

[0013]

【Example】

 Examples will be described with reference to the drawings. In the figure, 11 is an agricultural water reservoir, and 12 is an embankment. The siphon tube suction part 6 is held by a float 4 made of lightweight synthetic resin such as expanded polystyrene or metal, and is floated on the agricultural water pond 11 and kept at a certain depth from the water surface. Further, the flexible sifion pipe 1a is connected to the sifion pipe suction portion 6 and the connection pipe 7 provided on the bank 12, and further connected to the water conduit 16 by the sifion pipe 1, and its discharge port is adjusted. A valve 3 is provided. The auxiliary tank 5 is connected to the upper portion of the connecting pipe 7.

At the beginning of installation, the outlet adjustment valve 3 is closed, the siphon-on pipes 1 and 1a and the auxiliary tank 5 are filled with water by a pump or the like (not shown), and the adjustment valve 3 is opened. Water flows into the water conduit 16 by the ON principle.

By closing the opening / closing valve 5b provided on the uppermost part of the auxiliary tank 5 connected to the upper part of the connecting pipe 7, the insides of the siphon pipes 1 and 1a auxiliary tank 5 and the connecting pipe 7 are shut off from the outside air. In addition, the water level in the auxiliary tank 5 drops due to the negative pressure inside while water is being taken in according to the principle of SIFON. However, when the adjustment valve 3 at the discharge port is closed and water intake is stopped, the negative pressure in the auxiliary tank 5 is reduced. Water is sucked up by the pressure, and the auxiliary tank 5 is filled with water. Even if air is sucked into the siphon tube, it will be stored in the auxiliary tank 5, so that the siphon tubes 1 and 1a and the connecting tube 7 are filled with water. It can be expected that a reliable Sifon principle will be formed when water is opened and water is taken.

This sifion type water intake device may be formed of synthetic resin, or may be made of metal or the like, and the materials are appropriate, and it is also possible to make a combination thereof, and the size is the scale of the agricultural pond to be installed. It is only necessary to determine by taking into account the amount of water taken up, the amount of water taken in, etc., and various things such as remote control and automatic control can be considered in addition to this example, but there is no difference in that it is a simple method of taking water using the principle of siphon .

[0017]

[Effect of device]

 Since the present invention is configured as described above, it is possible to reduce labor in the management of agricultural water ponds and enable safe and reliable surface water intake in response to changes in the water level of agricultural water ponds. is there.
