Bottom edge protruding type bulkhead gate device

Abstract

The invention relates to a bottom edge protruding type bulkhead gate device. The bottom edge protruding type bulkhead gate device comprises a bulkhead gate panel composed of a series of bins separatedby longitudinal beams and cross beams, wherein a lifting lug is installed at the upper end of the bulkhead gate panel. A bottom edge capable of protruding is additionally arranged at the bottom of the incident flow face of the bulkhead gate panel, the bottom edge is installed at the front edge of the bottom of the bulkhead gate panel through a rotating shaft, electromagnets are installed in the bins at the bottom of the bulkhead gate panel, and compression spring are separately fixed at the position, between the bottom edge and the bin bottom, of corresponding positions at both ends of the electromagnets. According to the bottom edge protruding type bulkhead gate device, after the bottom edge capable of protruding is additionally arranged, the effective action area of water weight is increased, the gate is conveniently closed. Extension or retraction of the bottom edge can be realized through the electromagnets and the springs, the structure is simple, the construction is convenient,and the manufacturing cost is low.

Description

technical field [0001] The invention discloses a flat gate device with a protruding bottom edge driven by a magnet, which is applied to the field of hydraulic engineering. Background technique [0002] In the field of water conservancy engineering, the main function of the slab gate is the gate that can be closed in the moving water when an accident occurs in the unit or waterway, through which the water flow can be cut off quickly, so as to prevent the expansion of dangerous accidents and avoid economic and property losses. With the construction of high-reservoir dams, the design water head is getting higher and higher, and the slider-type slab gate has the characteristics of simple structure, convenient and reliable operation and low cost, and is more and more widely used in water conservancy projects. Whether the flat plate accident gate can be closed normally in moving water and its hydrodynamic characteristics during the closing process are the focus issues in the desig...

AI Technical Summary

Problems solved by technology

In high dams and large reservoirs, due to the influence of high water head and large discharge flow, when the slider-type flat gate is soaked in water for a long time, the friction coefficient increases. The gate is difficult to close

The traditional method is to increase the counterweight of the gate to overcome the friction force, but the space of the flat gate is small, and the weight that can be used for counterweight is limited
