[0034] Among them, the gate frame 1, the driving mechanism 2, the lifting rod 3 and the gate body 4 are all existing structures of the hydropower station gate.

The arrangement of the power wheel group 6 and the power generation component 7 facilitates the use of the kinetic energy of the water in the gate frame 1 to drive the power wheel group 6 to rotate. The kinetic energy is converted into electrical energy by the power generation component 7 to generate direct current or alternating current. The electrical energy can be stored by the energy storage component 9. Then, the driving mechanism 2 and the winding component 11 are connected to the energy storage component 9 to facilitate the connection and use of the electric structure in the gate, realize the circulating energy supply of the energy storage component 9, reduce the electrical energy drive of the gate switch, and increase the energy saving of the gate. Then, the use of the interception net 13 facilitates the interception of large pieces of water plants and garbage in the river water flowing in the gate frame 1, prevent objects from being entangled in the power wheel group 6, and improve the power generation effect of the energy storage component 9.

[0035] like Figure 1 As shown, a bottom plate 10 is provided in the middle of both sides of the gate frame 1 and is located on the outside of the supporting side wall 5. A conveying pipe 8 electrically connected to the power generation component 7 and the energy storage component 9 is provided on the bottom plate 10.

Through the arrangement of the power wheel group 6, it is convenient to increase the kinetic energy conversion structure on the flood control gate, so that the gate can utilize the kinetic energy of the open river water to realize the power supply of the gate, wherein the plurality of impellers 16 are evenly distributed on the main shaft 15, and the impeller 16 is composed of a plurality of blades, and the blades are T-shaped. The water flow can drive the plurality of impellers 16 to rotate by flushing the blades on the plurality of impellers 16, so as to utilize the function.

[0037] like Figure 2 As shown, a plurality of guardrails 17 are provided between the edges of the two side plates 14. The plurality of guardrails 17 are distributed in an arc-shaped structure. The plurality of arc-shaped guardrails 17 can protect and block objects on the upper side, thereby preventing the entry of impurities when the power wheel group 6 rotates, thereby increasing the safety of the power wheel group 6.

[0038] like Figure 2As shown in Figure 3, the power generation component 7 includes a gear set 18 arranged on the side disc 14, a generator 19 arranged at the output end of the gear set 18, and an electric energy output line 20 arranged on one side of the generator 19.

The rotation of the side disc 14 can drive the large gear of the gear set 18 to rotate. After the large gear drives the small gear to rotate, the kinetic energy can be transmitted to the generator 19. The generator 19 uses the existing generator power generation technology and converts the induced current generated by the rotational motion into DC or AC rotational motion and electrical energy through the principle of electromagnetic induction, thereby realizing the power supply of the gate.

[0039] like Figure 6 As shown, the energy storage component 9 includes a plurality of lithium battery blocks 21 connected in parallel, and the energy storage component 9 is connected to the drive mechanism 2, wherein the drive motor 24 is electrically connected to the energy storage component 9. By applying the existing circuit connection technology, the parallel connection of the plurality of lithium battery blocks 21 facilitates increasing the power supply security between the plurality of lithium battery blocks 21, and the energy storage component 9 can transmit electrical energy to the drive mechanism 2, thereby realizing the self-sufficiency of electrical energy of the gate, reducing the use of the gate, and increasing the environmental protection and energy saving of the gate.

[0041] like Figure 4 As shown, the winding rope 12 and the winding bin 22 are distributed throughout, one end of the winding rope 12 is wrapped around the outside of the winding shaft 23, and a counterweight plate 25 is arranged between the other end of the winding rope 12 and the interception net 13. Through the rotation of the winding shaft 23, the winding rope 12 is conveniently wound on the winding shaft 23, providing kinetic energy for the winding or loosening of the winding rope 12, and the length of the winding rope 12 is greater than the length of the interception net 13. Through the use of the counterweight plate 25, the interception net 13 is convenient to be vertically expanded in the river channel, and the length of the interception net 13 is the same as the width of the gate frame 1, so as to intercept and filter the aquatic plants and large pieces of garbage flowing in the river channel.

[0042] When the embodiment of the present invention is used, the existing gate switching technology is applied, and the power drive of the driving mechanism 2 to the lifting rod 3 can drive the gate body 4 to adjust the height, closing or opening the gate in the river channel. When the gate is opened, the potential energy of the river flowing in the gate frame 1 will be converted into kinetic energy. Through the arrangement of the power wheel group 6 between the two supporting side walls 5, the river water can flush the blades on the impeller 16, driving the multiple impellers 16 on the main shaft 15 to rotate, and the side plate 14 outputs power to the power generation component 7, so that the rotating side plate 14 drives the large gear in the gear group 18 to rotate, and through the meshing connection between the large gear and the small gear, the large gear can drive the accelerated rotation of the small gear, so that the small gear can input kinetic energy to the generator 19, thereby improving the utilization of the kinetic energy of the gate river water, and then the existing generator is used to convert the kinetic energy into electrical energy, so that the existing generator power generation technology is used to convert the induced current generated by the rotational motion into DC or AC rotational motion through the principle of electromagnetic induction. The rotational motion is converted into electrical energy, and then through The delivery pipe 8 delivers the electric energy to the energy storage assembly 9, which can realize the electric energy storage of the gate. When the electrical equipment in the gate is used, the electric energy can be recycled through the energy storage assembly 9, the drive mechanism 2 and the winding rope 12, which reduces the external electric energy input of the gate and increases the energy saving of the gate. The drive motor 24 in the winding assembly 11 is then used to power the drive motor 24, so that the drive motor 24 can drive the winding shaft 23 to rotate, and the winding rope 12 is unscrewed from the winding bin 22, and the counterweight plate 25 is used to adjust the electric energy. The bottom of the interception net 13 is stretched so that the interception net 13 can be set vertically at the bottom of the river channel to filter the river water flowing in the gate frame 1, filter aquatic plants and isolate large pieces of garbage, and then drive the motor 24 to rotate in the opposite direction to reel the winding rope 12 into the winding bin 22, so that the counterweight plate 25 can be moved toward the bottom plate 10. When the interception net 13 is cleaned, the staff can stand on the bottom plate 10 to clean the outside of the reeled interception net 13, thereby improving the fluidity of the gate and increasing its service life.

[0043] The above is a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles described in the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
