Water conservancy irrigation gate device

Abstract

The invention discloses a water conservancy irrigation gate device. The water conservancy irrigation gate device comprises a channel formed in the ground and a gate frame fixed to the channel, and ischaracterized in that a driving mechanism is inserted into the top surface of the gate frame, the bottom end of the driving mechanism is connected with a gate, the gate is in contact connection with the gate frame, the channel is provided with a fixed groove, the fixed groove and the gate are arranged in a corresponding up and down mode, a filtering sludge scraping device is arranged at the top end of the fixed groove, the filtering sludge scraping device comprises a filter screen axially connected to the side wall of the fixed groove, a scraper is arranged at the end of the filter screen, a drainage pipe is inserted into the bottom end of the fixed groove, the end of the drainage pipe is connected with an water suction pump, and a water collecting pool is formed in the lower part of the water outlet side on the water suction pump. The water conservancy irrigation gate device is good in sealing performance, has no problem of irrigation water overflow waste, and the cleanness of the gate is improved, and the service life of the gate is prolonged.

Description

technical field [0001] The invention relates to the technical field of water conservancy engineering, in particular to a water conservancy irrigation gate device. Background technique [0002] Irrigation refers to watering the land, mainly including flood irrigation, sprinkler irrigation, micro-sprinkler irrigation, drip irrigation, seepage irrigation, and regulated deficit irrigation. The principle of irrigation is that the amount of irrigation, the frequency of irrigation and the time should be determined according to the water demand characteristics of medicinal plants, growth stages, climate, and soil conditions. Shortage of resources, frequent floods and droughts, special climate, geography and other natural and social conditions determine that China's agriculture must take the development path of irrigated agriculture. At present, water conservancy irrigation agriculture adopts the main channel to divert water to each farmland sub-canal for irrigation. The gate device...

AI Technical Summary

Problems solved by technology

At present, water conservancy irrigation agriculture adopts the main channel to divert water to each farmland sub-canal for irrigation. The gate device on the sub-canal controls whether the water is supplied, and the existing gate device blocks the water diversion in the sub-canal during the closing process. When the main channel stops water supply, Due to the problem of command delay, water will still be supplied to the branch channel. After the gate is closed, the water stored in the channel will continue to accumulate, causing it to overflow the channel and seep into the outer surface, resulting in a lot of waste of water resources. Not only that, When the gate is closed, due to the uneven surface of the channel after a long period of disrepair, there will be some gaps after the gate contacts the surface of the channel, and a lot of irrigation water will seep out of the gap, which will further expand the impact of water resource waste, so it is necessary to carry out this work. In-depth analysis to minimize the waste of irrigation water resources
