Counterweight-variable and hydraulic power-controllable automatic fixed shaft turning plate gate

Abstract

The invention discloses a counterweight-variable and hydraulic power-controllable automatic fixed shaft turning plate gate; a water tank is arranged at the lower part of the back side of a gate; the gate is connected with a rotating shaft; the rotating shaft is connected with a water fan in a water storage tank by penetrating through an open web type gate pier wall; a steel wire rope, supported by a bracket and a pulley, of a heavy hammer of a water collecting well pulls the water fan; and a reservoir is communicated with the water storage tank and the water collecting well by water inlet and outlet pipes. The gate with the water tank is arranged; when the gate is closed or opened, a counterweight is changed, so that the gate is flexible in opening or closing; the rotating shaft is fixedly connected with the gate, and is prevented from being blocked by floating impurities; a gate pier bracket and a baseplate bracket adopt different shapes to prevent floating objects from blocking a lock chamber to be in favor of safe flood discharge of a water gate; the heavy hammer of the water collecting well is arranged for pulling the water fan to solve manual control of gate opening degree and timing water diversion and to guarantee normal operation of the gate under special working conditions; and the water fan and a vibration reducing support prevent the opening / closing of the gate from colliding the gate pier bracket and a baseplate support pier of the locking chamber, so that the gate operation stability is guaranteed, and the engineering life is prolonged.

Description

technical field [0001] The invention relates to a gate, in particular to a variable counterweight controllable hydraulic automatic fixed-axis flap gate. Background technique [0002] The hydraulic automatic flap gate has the advantages of no external energy, simple structure, self-opening and closing under unmanned operation, reliable operation, convenient management and maintenance, and low cost. At present, the hydraulic automatic flap gate is divided into: (1) vertical shaft There are five types of revolving gates, (2) horizontal shaft revolving gates, (3) non-continuous hinged flap gates; (4) curved continuous hinged flap gates; (5) involute opening gates. Among them (1) the shaft of the vertical shaft revolving gate and the horizontal revolving gate cannot be fully automatically controlled. Once opened, the water volume is basically discharged, and the gate cannot automatically return to its position and close. It needs to be closed manually, and the upstream water leve...

AI Technical Summary

Problems solved by technology

Among them (1) the shaft of the vertical shaft revolving gate and the horizontal revolving gate cannot be fully automatically controlled. Once opened, the water volume is basically discharged, and the gate cannot automatically return to its position and close. It needs to be closed manually, and the upstream water level cannot be controlled artificially, which makes management troublesome; (2) non-continuous There are three types of gates, the hinged flap gate, the curved continuous hinged flap gate and the involute gate, which are complex in design and construction, and some gates have a small opening degree, which is unfavorable to the flood discharge of the project.

In addition, when the sluice is running, it will be blocked by a large number of floating objects, which will easily get stuck on the running track, resulting in inflexible opening of the sluice gate, or even failure to open the sluice gate for flood discharge, which will affect the safety of flood discharge in the project

The processing technology of the gate components is high (if a certain precision is required), and the maintenance and update costs are high

The above five types of gates are prone to beating, vibration and impact during the flipping process, which may easily cause damage to the door leaf and affect the life of the gate.

It is impossible to artificially control the opening of the gate under special working conditions, the flood discharge is unreliable, and the water volume cannot be automatically timed and quoted

The buttresses on the bottom plate of the gate block the discharge of floating objects, block the sluice, and affect the flood discharge of the sluice and other defects
