Problems solved by technology
[0003] In view of the above-mentioned related technologies, the inventor believes that the flap gate generally blocks the water flow, and there are many impurities and silt in the water, and generally moves with the water flow. When the water flow is blocked by the flap gate, the flow rate decreases, and the impurities and silt in the water Under the action of gravity, it slowly settles to the flap gate, and manual dredging is carried out directly. The engineering volume is relatively large, so it needs to be improved.

Embodiment
[0049] Embodiment A kind of implementation principle of the flap gate is: during the use of the flap gate, the cleaning filter screen 31 filters the impurities and silt in the water flow. At this time, the impurities and silt are all piled up on the cleaning filter screen 31; When cleaning, the operator winds the steel rope on the support net plate 32 in advance, at this time, the operator unscrews the locking bolt 413 from the locking blind hole 422, holds the toggle piece 423, moves and fixes the connecting arc rod 42, Make the fixed connection arc rod 42 retract into the fixed connection arc tube 41, at this time, the fixed connection arc rod 42 removes the limit on the support net plate 32, and the operator moves the support net plate 32 to the river bank smoothly by means of the steel rope through the crane After the support screen 32 is placed stably, the operator will remove the cleaning connecting ring 311 from the supporting connecting rod 321, and at this moment, the ...

The invention relates to a flap gate and a mounting method thereof, and relates to the field of flood control and water storage. The flap gate aims to solve the problems that a flap gate generally blocks water flow, more impurities and sludge exist in water and generally move along with the water flow, the flow speed is reduced after the water flow is blocked by the flap gate, the impurities and sludge in the water slowly settle to the flap gate under the action of gravity, and a work amount is relatively large if manual desilting is directly performed. The flap gate comprises a gate panel and gate supporting legs; the gate supporting legs are fixedly connected to the side wall of one side of the gate panel; a filtering assembly is arranged on the side wall, away from the direction of the gate supporting legs, of the gate panel; and a fixing assembly used for limiting the filtering assembly is further arranged on the side wall, away from the direction of the gate supporting legs, of the gate panel. The flap gate has the effect that the desilting work amount of the flap gate is reduced.
Description
technical field [0001] The present application relates to the technical field of flood control and water storage, in particular to a flap gate and an installation method thereof. Background technique [0002] The flap gate can automatically control the water level, and is mainly used to intercept or discharge water in reservoirs, rivers, reservoirs, etc. [0003] In view of the above-mentioned related technologies, the inventor believes that the flap gate generally blocks the water flow, and there are many impurities and silt in the water, and generally moves with the water flow. When the water flow is blocked by the flap gate, the flow rate decreases, and the impurities and silt in the water Under the action of gravity, it slowly settles to the flap gate, and manual dredging is carried out directly. The engineering volume is relatively large, so it needs to be improved. Contents of the invention [0004] In order to reduce the amount of dredging of the flap gate, the pre...
