Its operating principle is that when in use, the power supply is connected to control the motor to rotate. During the rotation of the motor, the driving rotating rod is driven to rotate through the pulley transmission mechanism. At the same time, the stirring blades rotate following the driving rotating rod through the snap ring. During the rotation of the stirring blades, the flow rate of the surrounding water will be accelerated, resulting in the water-facing surface of the gate not being easily frozen. Thus, it is realized that when the multi-functional water conservancy and hydropower gate water-facing surface anti-freezing device is in use, the phenomenon of ice formation on the water-facing surface of the gate can be effectively avoided. The device has high working efficiency, good anti-freezing effect, and strong practicability.

[0049] Working principle and usage process of the present invention: The present invention is used for anti-freezing on the water-facing side of the dam gate. When in use, the hydraulic telescopic rod 5 drives the anti-freezing drive assembly 4 and the anti-freezing stirring assembly 3 to move to an appropriate height. The anti-freezing drive assembly 4 drives the anti-freezing stirring assembly 3 to rotate to stir the water-facing side, so that the surrounding water flow hits the blocks, resulting in the water-facing side of the gate not being easily frozen. When in use, the ventilation and heat dissipation assembly 6 facilitates ventilation and heat dissipation inside the anti-freezing drive assembly 4. The solar energy assembly 7 facilitates converting light energy into electrical energy for the device's own use. When the ventilation and heat dissipation assembly 6 is in use, by starting the ventilation and heat dissipation fan 64, the wind is filtered through the dust-proof filter screen 66 and then flows into the ventilation and heat dissipation seat 61 through the rain-proof air inlet seat 62, and then enters the inside of the anti-freezing drive assembly 4 through the heat dissipation holes above the anti-freezing drive assembly 4 for ventilation and heat dissipation inside. Then the heat flows out through another heat dissipation hole above the anti-freezing drive assembly 4. The settings of the rain-proof air inlet seat 62 and the rain-proof air outlet seat 63 can prevent rainwater from seeping in. When it is necessary to disassemble, install, clean the dust-proof filter screen 66, by pulling the fixing rod 682, the fixing rod 682 drives the fixing slider 683 to move and compress the fixing spring 684, so that the fixing rod 682 disengages from the fixing hole on one side of the net cover 67, and then the net cover 67 can be removed, and thus the dust-proof filter screen 66 can be removed to clean or replace it. By unscrewing the sealing maintenance cover 69 and then removing the fixing screws, it is convenient to perform maintenance on the inside of the anti-freezing drive assembly 4. When the device is in use, it is convenient to ventilate and dissipate heat inside the transmission box of the anti-freezing drive assembly 4, preventing the internal heat from not being dissipated during long-term continuous operation, causing damage to the device. And when this structure is in use, through the fixing component 68, the dust-proof filter screen 66 can be quickly disassembled and installed to clean or replace the dust-proof filter screen 66. When the solar energy assembly 7 is in use, the solar power generation device 72 facilitates converting light energy into electrical energy for the device's own use. When it is necessary to clean the surface of the solar power generation device 72, by starting the cleaning motor 75, the cleaning motor 75 drives the cleaning screw rod 74 to rotate. The rotation of the cleaning screw rod 74 drives the square slider 76 to move, and the movement of the square slider 76 drives the cleaning brush 77 to move to clean the surface of the solar power generation device 72. When it is necessary to remove the cleaning brush 77 and replace it, by unscrewing the installation screws, then the cleaning brush 77 and the installation seat 78 can be separated, so as to replace the cleaning brush 77. The bird repelling motor 792 drives the connecting seat 793 to rotate, thereby driving the bird repelling reflector 794 to rotate, facilitating the dispelling of birds to prevent birds from staying near the solar energy assembly 7. The protective box 791 facilitates protecting the bird repelling motor 792. The heat conducting block 795 facilitates conducting the heat inside the protective box 791 out. When the device is in use, it is convenient to convert light energy into electrical energy for the device's own use, saving energy. And when this structure is in use, it is convenient to clean the surface of the solar power generation device 72, and through the bird repelling assembly 79, it is convenient to dispel birds to prevent birds from staying.
