Opening and closing device for a water gate

Abstract

The invention discloses an opening and closing device for a water gate, which relates to the technical field of water conservancy engineering. It has a gate frame assembly, a gate assembly and a drive assembly; the gate frame assembly includes a chassis at the bottom, columns on the left and right sides and a beam at the upper end; a horizontal lifting plate is fixed at the upper end of the casing; the upper surface of the lifting plate is evenly embedded A plurality of lower permanent magnets are installed; the upper end of the installation groove is sealed and matched with an elastic film; the gate assembly includes a cuboid gate body; the lower end surface of the gate body is sealed and matched with the elastic film; the lower end surface of the gate body is uniform A plurality of upper permanent magnets are embedded and installed; a pressure relief valve is installed at the rear end of the drain pipe; the drive assembly includes an opening and closing oil cylinder rotatably installed on the upper end of the beam; a horizontal rotating rod is installed at the top of the rotating shaft; The end of the piston rod is connected in a horizontal rotation with the rotating rod. The beneficial effects of the invention are that the sealing adjustment can be better realized, and the influence on the sealing caused by the accumulation of sand and gravel at the bottom is reduced.

Description

technical field [0001] The invention relates to the technical field of hydraulic engineering. Background technique [0002] Hydraulic gates are used to intercept water flow, control water level, regulate flow, etc. In the river channel, sediment has a great influence on the sealing connection of the gate. Whether it is a gate that is lifted up or down or a gate that is rotating, sediment may enter the sealing groove of the gate, affect the sealing closure, and cause wear to the seal. Generally, a spring lifting structure is adopted to fill the sealing groove when the gate is raised to prevent gravel from entering the sealing groove. At that time, the spring lifting structure itself and the sealing groove also adopt a sliding sealing structure, which may still be affected by the gravel and cause failures; and Gravel may still remain on the upper end of the lifting structure, which will damage the seal structure when the gate is pressed down.

Problems solved by technology

In the river course, sediment has a great influence on the sealing connection of the gate. Whether it is a gate that is raised up and down or a gate that is rotating, sediment may enter the sealing groove of the gate, affect the sealing closure, and cause wear to the seal, etc.

Generally, a spring lifting structure is adopted to fill the sealing groove when the gate is raised to prevent gravel from entering the sealing groove. At that time, the spring lifting structure itself and the sealing groove also adopt a sliding sealing structure, which may still be affected by the gravel and cause failures; and There may still be gravel remaining on the upper end of the lifting structure, which will damage the seal structure when the gate is pressed down
