Safety gate device used for water conservancy engineering and using method of safety gate device

Abstract

The invention discloses a safety gate device used for water conservancy engineering and a using method of the safety gate device. The device comprises a gate plate (9) used for blocking a water channel opening (1); an external thread sleeve (7) is fixedly connected to the upper side of the gate plate (9) and used for stretching into the hollow interior of a rotating shaft (6) and being in screw thread 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 drive motor box (5) installed on a structure base body (10); the backwater side of the gate plate (9) is provided with two rolling wheel bearing assemblies from top to bottom; and each rolling wheel bearing assembly comprises two bearing rolling wheels (88) which are opposite in the horizontal direction and are rotationally installed on the left side and the right side of the gate plate (9).

Description

technical field [0001] The invention relates to the field of water conservancy equipment, in particular to a safety gate device for water conservancy projects and a use method thereof. 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 dynamic...

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
