Problems solved by technology

[0003] The front surface of the gate is only in contact with the water and the surface is not in contact with the water. When the scorching sun exposes the back surface of the gate, the gate will crack and the service life will be shortened. And because the front surface of the gate is in contact with water, there will be algae on the front surface of the gate. Parasitism with screws and other organisms will also affect the service life of the gate in the long run. The existing gates lack mechanisms for cleaning algae and screws and other organisms

Abstract

The invention relates to the technical field of flap gates, in particular to a hydraulic control flap gate which is characterized in that a sunscreen mechanism comprises a rotating disc rotationally connected to the top of a gate, an inclined column is rotationally connected to the bottom of an inner cavity of the gate, a groove is formed in the top of the inclined column, and a first supporting block is fixedly arranged in the gate; a rotating shaft extending into the gate is connected to the bottom of the rotating disc in a penetrating mode, and the bottom of the rotating shaft is located at the bottom of an inner cavity of the inclined column and fixedly connected with the inner cavity of the inclined column. The five sets of sliding strips can slide out of the sliding grooves to extend under the operation, then the five sets of arc-shaped strips can gradually get away and be separated, when the five sets of arc-shaped strips gradually get away and are separated, the stacked sunscreen nets can be opened, and sunscreen on the rear surface of the gate can be achieved through the opened sunscreen nets.

Description

technical field [0001] The invention relates to the technical field of flap gates, in particular to a hydraulically controlled flap gate. Background technique [0002] The flap gate is the hydraulic self-control flap gate. Its working principle is the balance and rotation of the lever. Specifically, the hydraulic self-control flap gate uses the hydraulic force and the weight of the gate to balance each other, and the damping feedback system is added to achieve the purpose of regulating the water level. When the upstream When the water level rises, the gate will gradually open and discharge around the horizontal axis. On the contrary, if the upstream water level drops, the gate will gradually close and store water, so that the upstream water level is always kept within the range of design requirements. [0003] Only the front surface of the gate is in contact with water and the rear surface is not in contact with water. When the back surface of the gate is exposed to the hot ...
