Description

Technical Field

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

[0002] The flood discharge gate of a hydropower plant is an important working gate used to discharge flood water and regulate the water level of the reservoir. The working principle of the flood discharge gate is mainly to adjust the water flow and water level by opening and closing the gate. The gate drive mechanism realizes the opening and closing of the gate through hydraulic, electric or manpower.

[0003] The utility model patent with the authorization announcement number CN220565182U discloses a remote-controlled irrigation gate, which includes a mounting frame, a lifting assembly and a gate body. The gate body is mounted on the mounting frame, the lower end of the lifting assembly is connected to the upper end of the gate body, the lifting assembly is connected to the mounting frame, and a control box is arranged on the upper part of the mounting frame. The control box is provided with a power supply, a transceiver module and a control module. The outside of the control box is provided with a first switch, a second switch and an external connector. The power supply, the first switch, the control module, the transceiver module and the lifting assembly are electrically connected; the external connector, the second switch and the lifting assembly are electrically connected. The staff can wirelessly connect the external terminal to the control module through the transceiver module, and send a gate opening and closing instruction to the control module. The control module controls the operation of the lifting assembly, thereby controlling the gate body to move up and down, thereby opening and closing the gate. When the power in the power supply is used up, the staff can access the external power supply device through the external connector, and adjust the remote control mode to the manual operation mode by operating the first switch. The lifting assembly can be controlled to operate through the second switch to realize the manual operation of the gate. This ensures the timely opening and closing of the gate and controls the amount of water for irrigation. The staff can wirelessly connect the external terminal to the control module through the transceiver module and send the gate opening and closing command to the control module. The control module controls the operation of the lifting component to control the up and down movement of the gate body to open and close the gate. When the power in the power supply is used up, the staff can access the external power supply device through the external connector and adjust the remote control mode to the manual operation mode by operating the first switch. The lifting component can be controlled by the second switch to realize the manual operation of the gate. This ensures the timely opening and closing of the gate and controls the amount of water for irrigation.

[0004] Although the control box set up in the remote-controlled irrigation gate is convenient for remote control of the gate, the control box set up in the device still has the following shortcomings in actual use: the control box is used outdoors in a harsh environment. In order to ensure the normal operation of the control box and the normal use of the gate, it is necessary to perform daily maintenance on the equipment in the control box. However, since the installation height of the control box is relatively high and it is fixedly installed between the control box and the gate, it is difficult to disassemble and assemble the control box at a later stage, which increases the difficulty of inspecting and maintaining the control module in the control box. In view of this, we propose a remote control device for the flood discharge gate of a hydropower plant. Utility Model Content

[0037] Furthermore, a screw rod 30 is rotatably installed in the vertical slot 111, the screw rod 30 passes through the driving plate 32 and is threadedly connected to the driving plate 32, and a second motor 31 for driving the screw rod 30 to rotate is installed on the top of the horizontal plate 12. This design facilitates the lifting and lowering of the driving plate 32 and the bearing plate 33, and has the advantage of easy operation.

[0038] In this embodiment, both side walls of the vertical slot 111 are fixedly connected with guide rails 112 by bolts, and both side walls of the driving plate 32 are provided with slide grooves 321 slidably connected with the guide rails 112.

[0045] It should be added that, since the supporting plate 33 in this embodiment needs to be raised and lowered, when laying the cable connecting the control module 37 and the wireless transceiver module 38, a part of the length can be reserved to meet the need to pull the cable when the supporting plate 33 is raised and lowered, or a telescopic spiral cable can be used. When the supporting plate 33 is raised and lowered, the cable can be stretched. This design not only meets the lifting requirements of the supporting plate 33, but also meets the requirements of signal and power transmission.

[0048] When the remote control unit 3 needs to be maintained, the user turns on the power of the second motor 31, and the second motor 31 starts to work. The output shaft of the second motor 31 rotates to drive the screw rod 30 to rotate. As the screw rod 30 rotates, the driving plate 32 moves downward along the vertical groove 111, and the driving plate 32 drives the supporting plate 33 to move downward. At this time, the supporting plate 33 drives the waterproof platform 34 and the mounting plate 36 to move downward, and the mounting plate 36 drives the control module 37 and the wireless transceiver module 38 to move downward. When the mounting plate 36 is detached from the protective cover 39, the user stops the power of the second motor 31 and can maintain the control module 37 and the wireless transceiver module 38.
