Irrigation and draining brake

Abstract

The invention discloses an irrigation and draining brake which comprises a flashboard frame and a flashboard, wherein a water inlet through hole is formed in the flashboard frame. Guide grooves are formed in both sides of the flashboard frame. Both sides of the flashboard are contained in the guide grooves and can move along the guide grooves, positioning adjusting teeth are arranged on the inner wall of the guide grooves, and elastic clamping tongues which are matched with the positioning adjusting teeth are arranged on both sides of the flashboard. The irrigation and draining brake is fixed on an opening of a ridge, irrigation and draining work is controlled by moving the flashboard, and water level height can be adjusted. The irrigation and draining brake has the advantages of being convenient to use, safe and reliable.

Description

technical field [0001] The invention relates to farmland water conservancy technology, in particular to an irrigation and drainage sluice. Background technique [0002] In the farmland where aquatic crops are planted such as rice and wild rice, it is necessary to set irrigation outlets and drainage outlets on the ridges to facilitate the introduction of water in the canals or the discharge of water from the paddy fields; After the irrigation or drainage is completed, fill it back with soil, stones, or bricks. That is to say, the work of excavation and filling must be repeated every time the irrigation and drainage are completed. The gap is easy to be washed by the water flow. In this way, there is no way to adjust the height of the water level when watering. It can only be observed with the naked eye. Therefore, during the watering process, people have to wait by the side, which is a waste of time; There is a problem. In the rainy season, a large amount of rainwater accumul...

[0002] In the farmland where aquatic crops are planted such as rice and wild rice, it is necessary to set irrigation outlets and drainage outlets on the ridges to facilitate the introduction of water in the canals or the discharge of water from the paddy fields; After the irrigation or drainage is completed, fill it back with soil, stones, or bricks. That is to say, the work of excavation and filling must be repeated every time the irrigation and drainage are completed. The gap is easy to be washed by the water flow. In this way, there is no way to adjust the height of the water level when watering. It can only be observed with the naked eye. Therefore, during the watering process, people have to wait by the side, which is a waste of time; There is a problem. In the rainy season, a large amount of rainwater accumulates and the water level in the field rises. It is very common for the crops to be drowned because the excess water is not discharged in time; another is to build grooves on both sides of the irrigation channel. Put wooden rams inside, and raise the water level when pouring water to achieve the purpose of blocking water into the field. This kind of wooden rams is perishable and has poor sealing performance, so the water blocking effect is not ideal.
