Problems solved by technology

[0004] Aiming at the deficiencies in the prior art, the present invention provides a flood discharge device for reservoirs. The purpose is to solve the existing flood discharge devices for reservoirs. The gate can flexibly adjust the water level only by means of power supply, driving device and detection equipment. Repeatedly inspect and monitor the water level, and adjust the opening and closing of the gate according to the water level, which is a waste of labor

Embodiment 2

[0042] Example 2, such as Picture 10 , The structure is basically the same as that of Embodiment 1, except that the lower part of the dam body 10 is provided with a secondary drainage hole 9. The secondary drainage hole 9 is a circular through hole penetrating the dam body 10, and the secondary drainage hole 9 is overall Arc shape, the left and right end faces of the dam body 10 corresponding to the secondary drain hole 9 are respectively provided with a third wear ring 90 matching its end face, the third wear ring 90 is a ring body with a central opening; the secondary drain hole 9 Continuous drainage to ensure the stable water level of reservoir 6 and reduce the drainage pressure of the first gate 2.

[0043] Rotate the hand wheel 43, the worm 41 rotates, the rotating worm 41 drives the worm gear 40 to rotate, and at the same time the screw on the worm wheel 40 rotates, the rotating screw drives the connecting rod 3 to move up and down, the first gate 2 moves up and down, the f...

Abstract

The invention relates to a reservoir flood discharge device which comprises a dam, a first gate, a connecting rod, a transmission device and a movable gate. The dam is arranged at an exit of areservoir and connects mountains at both ends of the reservoir. The dam comprises a dam body and a dam bottom, and a water drainage hole is formed inthe lower part of the dam body, the dam body is provided with a first abrasion resistance ring, a connecting rodis fixed to the upper part of the first gate, the transmission device comprises a worm wheel, a worm, a shell and a hand wheel, and the edge of theworm wheel is connected with a stud, aflood discharge hole is formed in the upper part ofthe dam body, andthe movable gate is hinged to the step surface in the flood discharge hole; and the movable gate is hinged to a hinge shaft, and the hinge shaft is a shaft body inclined from the front upper direction and the lower part in a vertical surface.The problems that an existing reservoir flood discharge device must rely on a power supply, a driving device and testing equipment to enable a gate to flexibly adjust the water level,it is necessary to repeatedly inspect and monitor the water level ifthe gate isopened and closed by using manpower to adjust the water level,the gate opening and closing is adjusted according to the water level, and manpower is wasted are solved.

Description

Technical field [0001] The invention relates to the field of water conservancy engineering, in particular to a reservoir flood discharge device. Background technique [0002] Reservoirs, water conservancy projects that block flood water and regulate water flow, can be used for irrigation, power generation, flood control, and fish farming; it refers to artificial lakes formed by the construction of barrages at the narrow mouths of mountains or rivers. After the reservoir is completed, Plays the role of flood control, water storage and irrigation, water supply, power generation, fish farming, etc.; due to continuous heavy rainfall, the reservoir exceeds the water level. In order to avoid flooding, or the collapse of reservoir dams and dikes, it is necessary to open the gate Drain the downstream flood discharge area. [0003] The existing flood discharge device of the reservoir is to build a dam at the exit of the reservoir. A gate is set in the dam. The gate can adjust the water lev...
