Description

Electric-manual double-drive switching water diversion gate Technical Field The invention relates to the technical field of sluice gates, in particular to an electric-manual double-drive switching water diversion gate. Background The gate of the water diversion gate is a key facility in hydraulic engineering, agricultural irrigation and water resource allocation systems, and has the core function of accurately controlling the on-off and flow of water flow in channels or river channels The traditional water diversion gate is mainly divided into an electric driving type and a manual driving type. The electric drive gate relies on the motor as the power supply, but possess simple operation remote control and degree of automation advantage such as high, be applicable to daily frequent operation of opening and close. However, the electric gate is obviously disadvantageous in that the electric gate is completely dependent on power supply, and is paralyzed when encountering emergency situations such as power failure, equipment damage or natural disasters, and the electric gate cannot execute key opening and closing operations, so that water conditions are out of control, and safety threat is formed to downstream areas or normal water supply scheduling is influenced. The manual driving gate does not depend on external power, can work under any condition through manual operation, has high reliability, but has the same defects that the operation is completely dependent on manpower, is generally laborious, has low opening and closing speed and low efficiency, and is difficult to meet the requirements of quick response and accurate control in modern water conservancy management, especially on a large gate. In order to solve the above problems, in the prior art, a gate design combining an electric function and a manual function appears, but there are often problems of complex switching mechanism, inconvenient operation, low reliability and the like, a common switching mode may need to move or disassemble large parts, a complicated process may delay the operation time under an emergency, in addition, many electric transmission systems do not have a self-locking function, when power is lost, the gate may generate unexpected displacement under the action of water pressure, potential safety hazards exist, and meanwhile, operators are difficult to intuitively and rapidly judge whether an electric driving part is in a normal working state in a control room, which is not beneficial to daily maintenance and fault early warning of equipment. Therefore, an electric-manual double-drive switching water diversion gate which is reasonable in design, convenient to switch, safe, reliable and has a state monitoring function is urgently needed. Disclosure of Invention According to the technical problems, the invention provides the electric-manual double-drive switching water diversion gate which can be controlled in an electric mode in a high efficiency under normal conditions, can be quickly and stably switched to a manual operation mode when power is interrupted or a motor fails, and simultaneously ensures that a transmission system has good self-locking performance and a state indicating function under any mode so as to comprehensively improve the running reliability, safety and intelligent management level of the water diversion gate.
