Protective device of reservoir gate

Abstract

The invention relates to a protective device of a reservoir gate. The protective device comprises a gate body, and further comprises a bearing frame, a movable plate, circulating cylinders and a driving mechanism; the bearing frame comprises a mounting plate and a mounting frame, the mounting plate is fixed to the front side of the gate body, and the mounting frame is installed on the front side face of the mounting plate; the movable plate is movably installed between the opposite side faces of a left vertical plate and a right vertical plate on the lower side of a lower plate body; the circulating cylinders comprise the left circulating cylinder body and the right circulating cylinder body which are the same in structure and size; the left circulating cylinder body and the right circulating cylinder body are correspondingly installed at the left parts and the right parts of the upper plate body and the lower plate body, and are in a bilateral symmetry state; and the driving mechanismcomprises a driving rod and a driving motor, wherein the driving rod comprises an upper rod body and a lower rod body. According to the protective device of the reservoir gate, the problem that the reservoir gate is extruded and deformed due to icing and expansion of water in a reservoir is solved, the water on one side of the upstream face of the reservoir gate is prevented from icing, the harmof icing of water to the gate is reduced, and the service life of the gate is prolonged.

Description

technical field [0001] The invention relates to the technical field of gates, in particular to a protection device for a reservoir gate. Background technique [0002] Reservoirs are water conservancy engineering structures for flood storage and water regulation. Reservoirs are generally artificial lakes formed by building barrages at the narrow mouths of ravines or rivers. As an important water conservancy facility, after the reservoir is completed, it is necessary to build a reservoir gate. The gate is used to close and open the control facility of the discharge channel. As an important part of the hydraulic structure, the gate can be used to intercept the water flow. Control water level, adjust flow, discharge sediment and floating objects, etc. [0003] However, in cold regions, the waters where the gates are located are prone to freezing, and the water expands with heat and contracts with cold during the process of freezing or melting, and the ice will squeeze the gates...

AI Technical Summary

Problems solved by technology

[0005] In order to solve the problem that the water in the reservoir freezes and expands to cause extrusion and deformation to the reservoir gate, the invention provides a protection device for the reservoir gate, which can prevent the water from freezing on the side facing the water of the reservoir gate and reduce the impact of water freezing on the gate. Harm, improve the service life of the gate
