Opening and closing device for a water gate

Abstract

The invention discloses an opening and closing device of a sluice gate, and relates to the technical field of water conservancy projects. The device comprises a gate frame assembly, a gate assembly and a driving assembly, the gate frame assembly comprises a bottom plate at the bottom, vertical columns on the left side and the right side and a cross beam at the upper end, a horizontal jacking plateis fixedly arranged at the upper end of a sleeve, a plurality of lower permanent magnets are uniformly embedded in the upper end surface of the jacking plate, an elastic membrane is arranged at the upper end of a mounting groove in a sealing fit mode, the gate assembly comprises a cuboid-shaped gate body, the lower end surface of the gate body is in sealing fit with the elastic membrane, a plurality of upper permanent magnets are uniformly embedded in the lower end surface of the gate body, a pressure relief valve is installed at the rear end of a drain pipe, the driving assembly comprises adriving motor installed at the upper end of a cross beam, and a follow-up gear is installed at the upper end of a rotating shaft. The device has the beneficial effects that sealing adjustment can be better realized, and the influence of bottom gravel accumulation on sealing is reduced.

Description

technical field [0001] The invention relates to the technical field of sluice gate opening and closing equipment. 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
