Problems solved by technology

The friction coefficient of the slider-type flat gate device is large. When soaked in water for a long time, the flat gate will be subject to a large thrust of the water flow when it is closed, resulting in difficulty in closing the gate.
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

Embodiment 1

[0017] The specific structure of the present invention will be further described below in conjunction with the accompanying drawings.

[0018] like Figure 1 to Figure 3 The flat gate device shown includes a flat gate, a hydraulic arm 1, a lifting lug 2, a warehouse 3, a beam 4, a longitudinal beam 5, a hinge point 6, a crank 7, a slider 8, a bearing seat 9, a rotating shaft 10 and a bottom edge 11 .

[0019] During the opening and closing process of the flat gate, the hoist pulls the lifting lug 2 through the pull rod to realize the lifting of the gate. The gate is made up of a series of beams 4, longitudinal beams 5, warehouses 3 between the beams and slabs. When the flat gate is closed, as the opening decreases, the water gravity and horizontal force on the gate increase simultaneously. When the gate is soaked in water for a long time, the friction coefficient will increase. When the friction coefficient is too large, the vertical force of the gate will increase. The axi...

Abstract

A bulkhead gate device comprises a bulkhead gate and a lifting lug above the bulkhead gate, wherein the bulkhead gate consists of a set of bins consisting of a series of transverse beams, longitudinalbeams and beam slabs. A bottom edge structure is arranged in the lowermost bin of the bulkhead gate; the bottom edge structure comprises a bottom edge; one of sides of the bottom edge is provided with a rotating shaft; two ends of the rotating shaft are arranged at the outer edge of the lowermost bin through bearings and bearing blocks; each of two ends of the other side of the bottom edge is hinged with one end of a crank through a hinge joint; the other ends of the cranks are hinged with one end of a sliding block; the sliding block is connected with the tail end of a transverse push rod atthe bottom part of an L-shaped hydraulic arm; and the vertical part of the L-shaped hydraulic arm penetrates through the gate and extends to the top part of the gate and communicates with an externalhydraulic system. After the protruding bottom edge is added on the device, the effective action area of water weight is increased, and the gate is helped to be closed, and moreover, the bulkhead gatedevice is simple in structure, convenient in construction and comparatively low in manufacturing cost.

Description

technical field [0001] The invention discloses a hydraulically driven flat gate device with a variable bottom edge angle, which is applied in the field of water conservancy engineering. Background technique [0002] In the field of water conservancy engineering, the main function of the flat gate is to close the gate 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, plane gates are more and more widely used in water conservancy projects as emergency gates because of their simple structure, convenient and reliable operation, and easy coordination with the layout of buildings. However, due to the influence of high water head and large discharge flow, whether the flat emergency gate can be closed normally in moving water and its hydrodynamic characteristics during the c...
