Description

Technical Field

[0001] The utility model relates to the technical field of remote control devices, in particular to a remote control device for tailwater accident gates of a hydropower plant. Background Art

[0002] The tailwater accident gate of a hydropower plant is a key device for the safe operation of the hydropower station. It is used to quickly cut off the water flow in an emergency to prevent the accident from expanding. The traditional tailwater accident gate control system usually relies on on-site manual operation or simple local control. This method has problems such as slow response, inconvenient operation, and inadequate monitoring, and cannot meet the growing automation and safe operation needs of hydropower stations.

[0003] At present, in order to save manpower and facilitate operation, remote control devices are usually used for remote control operations. This type of remote control device is generally composed of a remote monitoring center, a communication module, a control module and an actuator. The remote monitoring center is used to receive and process the tailwater accident gate status information from the hydropower plant and issue control instructions. The communication module is responsible for establishing a communication connection between the remote monitoring center and the hydropower plant to ensure real-time transmission of information. The control module accurately controls the actuator according to the control instructions of the remote monitoring center to drive the tailwater accident gate to perform corresponding actions. The actuator includes a drive device and a gate actuator, which is used to drive the tailwater accident gate to open or close according to the instructions of the control module, so as to achieve the effect of convenient remote control.

[0004] However, when using this type of remote control device, most of the basic electronic components are installed in the corresponding control host, and all electronic components are fixed by screws. All electronic components are hidden in the host. Due to the limited internal space of the host, the internal electronic components cannot be taken out for maintenance, which will cause inconvenience to subsequent maintenance operations, delay time, and affect maintenance efficiency. In view of this, we propose a remote control device for the tailwater accident gate of a hydropower plant. Utility Model Content
