[0006] A first photoelectric switch and a second photoelectric switch are installed on the supports on both sides of the locking beam. The first photoelectric switch is used to detect the vertical position of the locking beam, and the second photoelectric switch is used to detect the horizontal position of the locking beam.

[0007] It also includes a controller, the first photoelectric switch and the second photoelectric switch are connected to the input end of the controller, and the telescopic mechanism is connected to the output end of the controller.

The wireless transmitting end is connected to the gate lifting machine, and the wireless receiving end is buried in the dam body of the hydropower station. The wireless receiving end is connected to the battery and the telescopic mechanism in turn.

[0010] The beneficial effects of the utility model are:

[0011] 1. Improve operational efficiency: Automated control reduces manual intervention, increases gate operation speed, and shortens opening and closing time.

[0012] 2. Reduce maintenance costs: Reduce human error and equipment damage, and reduce daily maintenance costs.

[0013] 3. Enhanced safety: Real-time monitoring and feedback mechanisms ensure accurate gate movement to avoid safety accidents.

[0023] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0024] like Figures 1 to 6As shown, an automatic flipping device for the locking beam 6 of a hydropower station gate comprises a support 1 fixedly connected to a dam body 9 of the hydropower station, a locking beam 6 hinged on one side or both sides of the support 1, a support hinge seat 3 fixedly connected to the support 1, a telescopic mechanism 4 for driving the locking beam 6 to rotate is hinged between the support hinge seat 3 and the locking beam 6, the telescopic mechanism 4 being an electric cylinder, a limit rod 2 fixedly connected to the support 1 on one side of the locking beam 6, and a top block 8 corresponding to the limit rod 2 fixedly connected to one end of the locking beam 6. When in use, after the gate crane lifts the gate, the electric cylinder drives the locking beam 6 to a horizontal state, allowing the top block 8 to rest on the limit rod 2, and then the gate crane drops the gate, allowing the pillars on both sides of the gate to fall on the locking beam 6, thereby completing the locking of the gate.

[0025] A first photoelectric switch 5 and a second photoelectric switch 7 are mounted on the supports 1 on both sides of the locking beam 6. The first photoelectric switch 5 is used to detect the vertical position of the locking beam 6, and the second photoelectric switch 7 is used to detect the horizontal position of the locking beam 6. A PLC controller is also included, with the first photoelectric switch 5 and the second photoelectric switch 7 connected to the controller input, and the telescopic mechanism 4 connected to the controller output. The first photoelectric switch 5 and the second photoelectric switch 7 monitor the horizontal and vertical positions of the locking beam 6 and feed the monitoring information back to the PLC controller, which controls the start and stop or forward and reverse rotation of the electric cylinder to ensure that the locking beam 6 can be accurately flipped to the position so that it can cooperate with the gate lifting machine. When action is required, after receiving the signal that the gate lifting machine has completed the lifting, the locking beam 6 automatically locks and flips. After the action is in place, the action completion signal can be fed back to the door machine.

[0026] The controller is wirelessly connected to the client via a wireless transmission module. The client is the computer in the centralized control room, which makes it convenient for staff to remotely detect and control in the centralized control room.

[0027] The system also includes a wireless charging device, comprising a wireless receiving terminal 11 and a wireless transmitting terminal 10. The wireless transmitting terminal 10 is connected to the gate hoisting machine, and the wireless receiving terminal 11 is embedded in the hydropower station dam body 9. The wireless receiving terminal 11 is sequentially connected to the battery and the telescopic mechanism 4. The wireless power supply system on the hoisting machine enables remote, contactless power transmission, and the power storage device stores electrical energy, ensuring rapid power supply when action locking is required. At the same time, if the main power supply fails, the backup power supply will automatically start, providing continuous power support for the entire device.

[0028] The contents described in the embodiments of this specification are merely an enumeration of the implementation forms of the utility model concept. The protection scope of the utility model should not be regarded as limited to the specific forms described in the embodiments. The protection scope of the utility model also extends to equivalent technical means that can be thought of by those skilled in the art based on the concept of the utility model.
