The two positioning quick-lock support components are used to support the frequency conversion ultrasonic bird repeller 1 and the photovoltaic energy storage power supply component, respectively. They are also used to cooperate with the U-shaped abutment plate 402 at the high position for stable locking. When the sliding sleeve 301 moves down, they are used to automatically unlock and drive the frequency conversion ultrasonic bird repeller 1 and the photovoltaic energy storage power supply component to move down to the low position, so that personnel can carry out safe maintenance and disassembly work at a low position without climbing. The photovoltaic energy storage power supply component is used to store electricity using solar energy and power the frequency conversion ultrasonic bird repeller 1.

[0018] Furthermore, such as Figure 2 and 3As shown, the threaded vertical guide drive assembly includes a screw 207, a lifting seat 205, two vertical guide rods 206, a worm gear 203, a worm 202, and a rocker plate 204. The screw 207 is rotatably installed between the top inner wall of the U-shaped upright 3 and the top inner wall of the box-shaped support 2. The lifting seat 205 is fixedly connected between the inner walls on both sides of the sliding sleeve 301. The lifting seat 205 is threaded onto the screw 207. The two vertical guide rods 206 are fixedly connected between the top inner wall and the bottom inner wall of the U-shaped upright 3. The lifting seat 205 is slidably installed on the two vertical guide rods 206. The worm gear 203 is located inside the box-shaped support 2 and is fixedly connected to the bottom end of the screw 207. The worm 202 is rotatably embedded in the right inner wall of the box-shaped support 2 and meshes with the rear side of the worm gear 203. The right end of the worm 202 extends to the outside of the box-shaped support 2 and is fixedly connected to the left side of the rocker plate 204. In this embodiment, the top of the lifting seat 205 is provided with a threaded hole that is threadedly connected to the screw 207. The threaded connection between the screw 207 and the threaded hole facilitates the upward and downward displacement of the lifting seat 205 when the screw 207 rotates. The top of the lifting seat 205 also has two vertical guide holes that slide and fit onto the outer side of the corresponding vertical guide rod 206, providing vertical sliding guidance for the lifting seat 205. The bottom inner wall of the U-shaped upright 3 has a section for the screw 207 to pass through. The box-shaped support 2 has a through hole on its top inner wall. A first bearing is fixedly connected to both the through hole and the top inner wall of the U-shaped upright 3. The inner side of the inner ring of the first bearing is fixedly connected to the outer side of the screw 207, which serves to rotate the screw 207. The box-shaped support 2 has a through hole on its right inner wall. Two second bearings are fixedly fitted inside the through hole. The inner side of the inner ring of the second bearing is fixedly fitted to the outer side of the worm gear 202, which serves to rotate the worm gear 202. In this embodiment, the screw 207, lifting seat 205, two vertical guide rods 206, worm gear 203, worm 202 and rocker plate 204 work together. By rotating the rocker plate 204, the worm 202 is driven to rotate. The worm 202 drives the worm gear 203 that meshes with it to rotate. The worm gear 203 drives the screw 207 to rotate. The rotation of the screw 207 causes the lifting seat 205 to slide downward or move upward on the two vertical guide rods 206. The lifting seat 205 is used to drive the sliding sleeve 301 to slide downward or move upward on the U-shaped upright 3.

[0019] Furthermore, such as Figure 3As shown, the positioning fast card support assembly includes a rectangular sleeve 4, an L-shaped iron support plate 401, and a magnet. The two rectangular sleeves 4 are welded to both sides of the sliding sleeve 301. The two L-shaped iron support plates 401 are movably fitted into the corresponding rectangular sleeves 4. The two magnets are fixedly connected to the top of the two rectangular sleeves 4 on the opposite side and are attracted to the top inner wall of the corresponding L-shaped iron support plate 401. The frequency conversion ultrasonic bird repeller 1 is fixedly installed on the top of the L-shaped iron support plate 401 on the right side. The U-shaped abutment 402 is pressed against the top of the corresponding L-shaped iron support plate 401. In this embodiment, U-shaped handles are fixedly connected to both the front and rear sides of the L-shaped iron support plate 401; In this embodiment, the rectangular sleeve 4, the L-shaped iron support plate 401, and the magnet cooperate to secure the L-shaped iron support plate 401 within the corresponding rectangular sleeve 4. The U-shaped abutment plate 402 abuts and restricts the tops of the two L-shaped iron support plates 401 at a high position, preventing them from slipping out and achieving a locking and securing effect. The right-side L-shaped iron support plate 401 supports the variable frequency ultrasonic bird repeller 1, and the left-side L-shaped iron support plate 401 supports the photovoltaic energy storage power supply component. When the sliding sleeve 301 moves downwards... Two rectangular sleeves 4 move two L-shaped iron support plates 401 down to a lower position and separate from the U-shaped abutment plate 402 to release the abutment fixation state, achieving the effect of downward adjustment and integrated release. By moving down to a lower position, it is convenient for personnel to directly and safely inspect and maintain the frequency-controlled ultrasonic bird repeller 1 without climbing. By releasing the fixation, personnel can directly pull the L-shaped iron support plate 401 upward from the lower part to separate it from the rectangular sleeves 4, achieving the effect of convenient disassembly and assembly of the L-shaped iron support plate 401 after downward movement. This facilitates the convenient disassembly and assembly of the frequency-controlled ultrasonic bird repeller 1 and the photovoltaic energy storage power supply component for subsequent disassembly, assembly, inspection, and maintenance work.

[0020] Furthermore, such as Figure 1 , 2 As shown in Figure 3, the photovoltaic energy storage power supply component includes a solar panel 5 and a lithium battery 501. The solar panel 5 is tilted and fixedly installed on the top of the L-shaped iron support plate 401 on the left side. The lithium battery 501 is fixedly installed on the inner wall of the top of the L-shaped iron support plate 401 on the left side. A photovoltaic charging controller is fixed and electrically connected to the bottom of the solar panel 5. The photovoltaic charging controller is electrically connected to the lithium battery 501. An inverter is fixed and electrically connected to the front side of the lithium battery 501. The inverter is electrically connected to the frequency conversion ultrasonic bird repeller 1 through a wire. In this embodiment, four support legs are fixedly connected in a rectangular shape between the bottom of the solar panel 5 and the top of the L-shaped iron support plate 401 on the left side. In this implementation scheme, the solar panel 5, photovoltaic charging controller, lithium battery 501 and inverter work together to convert solar energy into electrical energy using the solar panel 5, charge the lithium battery 501 through the photovoltaic charging controller for energy storage, and convert the DC power in the lithium battery 501 into AC power using the inverter to power the frequency conversion ultrasonic bird repeller 1, thus achieving the effect of using solar energy for energy storage and powering the frequency conversion ultrasonic bird repeller 1.

[0021] Furthermore, telescopic protective sleeves 6 are fixedly connected to the top and bottom of the sliding sleeve 301. The opposing sides of the two telescopic protective sleeves 6 are fixedly connected to the top of the box-shaped support 2 and the inner wall of the top of the U-shaped abutment 402, respectively. The U-shaped upright 3 is located inside the two telescopic protective sleeves 6. The telescopic protective sleeves 6 are used to be compressed or stretched by the sliding sleeve 301 when it moves up and down. The two telescopic protective sleeves 6 provide safety protection for the screw 207 and other structures inside the U-shaped upright 3, achieving the effect of always safely protecting the screw 207 from dust, avoiding the jamming of external particles and impurities into the screw 207, and improving the stability of use.

[0022] It should be noted that the preferred variable frequency ultrasonic bird repeller 1 is the DL-S6223 model, manufactured by Yueqing Dalang Electric Appliance Co., Ltd. It employs a new type of sound and light integrated self-powered ultrasonic treatment method, utilizing high-brightness flashing, highly intelligent frequency sweeping mode, and continuously changing frequency ultrasonic repelling technology. It features over 40 frequency bands (1KHz-50KHz) for cyclical sweeping, interfering with the nervous systems of different birds and making them unable to adapt, thus achieving the effect of ultrasonic variable frequency bird repelling.

[0023] It should be further explained that the technology of converting solar energy into electrical energy through solar panel 5 and charging lithium battery 501 using photovoltaic charging controller, as well as the technology of converting DC power into AC power using inverter, are mature technologies in existing photovoltaic power supply systems. Furthermore, the selection of its components can be flexibly adapted according to the power consumption requirements of the entire equipment. These are all conventional methods or common knowledge in existing photovoltaic power supply systems, and will not be elaborated on here.

[0024] The usage method of this embodiment is as follows: When the variable frequency ultrasonic bird repeller is used, the solar panel 5 converts solar energy into electrical energy, and the photovoltaic charging controller charges the lithium battery 501 to perform power storage. The inverter converts the DC power in the lithium battery 501 into AC power to power the variable frequency ultrasonic bird repeller 1, thereby achieving the effect of using solar energy to store electricity and power the variable frequency ultrasonic bird repeller 1. The variable frequency ultrasonic bird repeller 1 continuously changes the frequency to interfere with the nervous system of different birds so that they cannot adapt, thereby achieving the effect of ultrasonic variable frequency bird repeller. When maintenance is required, personnel reverse the crank 204 to drive the worm gear 202 to rotate. The worm gear 202 drives the meshing worm wheel 203 to rotate, which in turn drives the screw 207 to rotate. The rotation of the screw 207 causes the lifting seat 205 to slide downwards on the two vertical guide rods 206. The lifting seat 205 causes the sliding sleeve 301 to slide downwards on the U-shaped upright 3, stretching and compressing the two telescopic protective rubber sleeves 6 respectively. When the sliding sleeve 301 moves downwards, it drives the two L-shaped iron support plates 401 to gradually move down to the lowest position through the two rectangular clamps 4, and separates from the U-shaped abutment plate 402 to release the limiting and fixing state, realizing the downward movement. The adjustment to a lower position and the integrated disassembly achieve the effect of allowing personnel to safely inspect and maintain the frequency-controlled ultrasonic bird repeller 1 from a lower position without having to climb, thus improving the convenience and safety of maintenance. Furthermore, by disassembling the device, personnel can directly pull the L-shaped iron support plate 401 upwards from the rectangular sleeve 4, making it easy to directly plug and unplug the L-shaped iron support plate 401 after the lower position. This facilitates the convenient disassembly and assembly of the frequency-controlled ultrasonic bird repeller 1 and the photovoltaic energy storage power supply component, enabling subsequent disassembly, assembly, inspection, and maintenance work. The operation is simple and improves the convenience of disassembly and assembly. After inspection and maintenance, the L-shaped iron support plate 401 is fitted into the corresponding rectangular sleeve 4 and initially attracted to the magnet. Then, the rocker 204 is rotated in the forward direction. Similarly, the movement direction of the rocker 204 is completely opposite to that of the reverse-starting rocker 204. At this time, the sliding sleeve 301 changes to moving upward and moves back upward through the two rectangular sleeves 4, thereby driving the two L-shaped iron support plates 401 to move upward and rise. This drives the variable frequency ultrasonic bird repeller 1 and the photovoltaic energy storage power supply component to rise and be applied, until the L-shaped iron support plate 401 moves up to the bottom of the U-shaped abutment plate 402. The top of the two L-shaped iron support plates 401 is abutted and restricted by the U-shaped abutment plate 402 at a high position, preventing them from being disengaged and moved upwards. This achieves the effect of abutting and locking the two L-shaped iron support plates 401, ensuring stability during use. The two telescopic protective sleeves 6 provide safety protection for the screw 207 inside the U-shaped upright 3, ensuring that the screw 207 is always protected from dust and preventing external particles and impurities from getting stuck inside the screw 207 and causing jamming, thus improving the stability of use.

[0025] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
