Gate device of hydraulic engineering and application method thereof

Abstract

The invention discloses a gate device of hydraulic engineering and an application method thereof. The device comprises a gate plate (9) for blocking a water channel opening (1); the upper side of the gate plate (9) is fixedly connected with an external thread sleeve (7) for extending in a hollow of a rotating shaft (6) to be in threaded fit with an internal thread ring part (71) at the lower end; the upper end of the rotating shaft (6) is connected with a motor rotor (51) in a driving motor box (5) mounted on a structure basal body (10); two roller support modules are mounted on the back water side of the gate plate (9) from top to bottom; and each roller support module includes two support rollers (88) oppositely and rotationally mounted on the left and right two sides of the gate plate (9) in the horizontal direction.

Description

technical field [0001] The invention relates to the field of water conservancy equipment, in particular to a gate device for a water conservancy project and a method for using the same. Background technique [0002] Gate devices are widely used in the field of water conservancy to control the water flow of water supply and drainage. In the existing gate devices, the height of the gate plate is often adjusted by screw drive to adjust the flow rate. Because the weight of the gate plate is often relatively large, it is easy to cause pressure damage to the screw drive pair due to the weight, especially in the case of impact. Moreover, the running smoothness of these gate plates is often poor and is prone to load fluctuations, thereby causing impacts on the transmission system. All of these pose safety hazards to the operation of the equipment. However, setting some locking devices driven by power or manually will easily cause multiple actuations in the case of multiple dynami...

AI Technical Summary

Problems solved by technology

Because the weight of the gate plate is often large, it is easy to cause pressure damage to the screw drive pair due to the weight, especially in the case of impact

Moreover, the smooth operation of these gate plates is often poor and prone to load fluctuations, resulting in impact on the transmission system

This poses a safety hazard to the operation of the equipment

However, setting some locking devices driven by power or manually will easily cause multiple actuations in the case of multiple dynamic adjustments to the height of the gate plate, resulting in a waste of labor costs and an increase in equipment operating costs.

And it is easy to cause the overall cost of equipment to rise and cause maintenance work to be complicated
