Irrigation gate of farmland canal for preventing cutting of water stop belt in internal groove

Abstract

The invention discloses an irrigation gate of a farmland canal for preventing cutting of a water stop belt in an internal groove. The irrigation gate of the farmland canal for preventing cutting of the water stop belt in the internal groove structurally comprises a fixed frame body, a water stop plate, a lifting screw, four limiting switches, a gear case and a driving motor. The water stop plate is vertically embedded into isolation grooves in the left and right sides of the fixed frame body, and a rotating block at the bottom end of the lifting screw is welded and fixed to the center of the top of the water stop plate. The limiting switches are arranged in pairs on the inner wall of the fixed frame body. A fixed flange on the left side of the driving motor is arranged on the right side ofa drive shaft of the gear case. In conclusion, after improvement is completed, gravel of the water stop belt is removed for cutting prevention protection, and meanwhile, the method of gradual meshingis adopted to ensure that no other impurities exist in a sealing contact clearance to affect the effect of water insulation.

Description

technical field [0001] The invention relates to an irrigation gate, in particular to an irrigation gate for farmland canals which prevents cutting of inner tank waterstops. Background technique [0002] Farmland irrigation often uses water from rivers and rivers, which is introduced into the farmland through ditches on the ground. The irrigation gates are installed in the first ditches and then diffused into the ditches for irrigation. The water flows into the gap of the gate. Modern farmland irrigation adopts automation to open the gate to release water and close the gate. The sediment and gravel will have a certain impact on the sealing of the gate when it is closed. The evaporation of crops in hot summer weather is large, and the irrigation gate is used. The frequency increases, because the limit stroke of the sluice is fixed, the gravel will be pressed down by the gravity of the baffle to pierce the rubber waterstop at the bottom, causing damage to the waterstop and affe...

Problems solved by technology

[0002] Farmland irrigation often utilizes water from rivers and rivers, which is introduced into the farmland through open canals on the ground. The irrigation gates are installed in the first canal and then diffused into sub-canals for irrigation. The water flows into the gap of the gate, and modern farmland irrigation adopts automation to open the gate, release water and close the gate. These sediments and gravel will have a certain impact on the sealing of the gate when it is closed. In hot summer, the evaporation of crops is large, and the irrigation gate is used. The frequency increases, because the limit stroke of the sluice is fixed, the gravel will be pressed down by the gravity of the baffle to pierce the rubber waterstop at the bottom, causing damage to the waterstop and affecting the sealing effect
