DETAILED DESCRIPTION

[0020] In order to make the purpose, technical solutions and advantages of the embodiments of the utility model clearer, the technical solutions in the embodiments will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. The following embodiments are used to illustrate the utility model but are not used to limit the scope of the utility model.

[0021] Embodiment 1:

[0022] Reference Figure 1 , Figure 2 A photovoltaic power station bird-repelling device includes a counterweight 1, and also includes: a rotating shaft 2 rotatably connected to the counterweight 1; a plurality of connecting shafts 201, which are fixedly connected to the outer wall of the rotating shaft 2 at equidistant circles; a wind cup 202, which is fixedly installed on the end of the connecting shaft 201 away from the rotating shaft 2; an air storage chamber 4, which is opened in the counterweight 1; a whistle 5, which is fixedly installed on the counterweight 1; a conduit 501, one end of which is fixedly connected to the whistle 5, and the other end is fixedly connected to the air storage chamber 4; a timer switch 502, which is arranged on the conduit 501, wherein the counterweight 1 is provided with a pressurizing component that uses wind power to drive the air storage chamber 4 to replenish gas.

[0023] When the wind blows, the wind will generate kinetic energy on the wind cup 202, causing it to start rotating and drive the rotating shaft 2 to rotate synchronously, thereby achieving the effect of driving away birds. Then, through the intermittent switch of the timing switch 502, when the timing switch 502 is turned on, the high-pressure gas stored in the air storage chamber 4 is transported into the whistle 5 through the conduit 501. The conduit 501 is provided with a one-way valve, which in turn drives the reed in the whistle 5 to vibrate and produce sound, thereby achieving the effect of intermittently driving away birds, further improving the effect of driving away birds.

[0024] Embodiment 2:

[0025] Reference Figure 2 , Figure 3 and Figure 4 , a photovoltaic power station bird-repelling device, which is basically the same as Example 1, and further, the booster component includes a piston cylinder 3 and a piston disk 301 slidably connected in the piston cylinder 3, the piston disk 301 is rotatably connected to a piston rod 302, the end of the piston rod 302 away from the piston disk 301 is rotatably connected to a crankshaft 303, the crankshaft 303 is fixedly connected to a rotating shaft 2, the piston cylinder 3 is fixedly connected to a pipe 1 304, the piston cylinder 3 is fixedly connected to an air storage chamber 4 through a pipe 2 305, and the piston cylinder 3 is fixedly connected to a counterweight 1.

[0026] It also includes a pressure relief pipe 401 , which is fixedly connected to the air storage chamber 4 , and a pressure relief valve is provided on the pressure relief pipe 401 .

[0027] An activated carbon filter is provided in the air inlet end of the pipe 1 304 .

[0028] When the rotating shaft 2 rotates, the rotating shaft 2 drives the crankshaft 303 to rotate. When the crankshaft 303 drives the piston plate 301 to slide back and forth in the piston cylinder 3 through the piston rod 302, the external gas is sucked into the piston cylinder 3 through the pipeline 1 304, and then transported into the air storage chamber 4 through the pipeline 2 305. The pipeline 1 304 and the pipeline 2 305 are provided with a one-way valve, so as to achieve the effect of replenishing gas into the air storage chamber 4, thereby preventing the air pressure in the air storage chamber 4 from being insufficient and affecting the normal use of the whistle 5;

[0029] If the air pressure added into the air storage chamber 4 is greater than the pressure relief value set by the pressure relief valve, the pressure relief valve automatically opens to relieve the pressure, so that part of the high-pressure gas in the air storage chamber 4 is discharged through the pressure relief pipe 401, thereby ensuring that the pressure inside the air storage chamber 4 is constant and preventing the pressure inside the air storage chamber 4 from being too high, causing safety hazards.

[0030] When the external gas enters the piston cylinder 3 through the pipe 304, it contacts with the activated carbon filter. Since the activated carbon has a developed void structure and abundant microporous tissue inside, these microporous tissues have a strong adsorption force field. When the gas contacts the activated carbon, the strong adsorption force field of the activated carbon micropores can adsorb the particulate matter in the air into the micropores, thereby achieving the effect of purifying the gas.

[0031] Embodiment 3:

[0032] Reference Figure 1 , Figure 2 A photovoltaic power station bird-repelling device is basically the same as Example 1, and further, the bottom outer wall of the counterweight block 1 is fixedly connected to a fixing frame 101, and the fixing frame 101 is provided with expansion bolts 102; when installing the bird-repelling device, first place the fixing frame 101 at a designated location, and drill a fixing hole on the ground with a diameter matching the expansion bolt 102, and then insert the expansion bolt 102 into the fixing hole to complete the installation of the bird-repelling device.

[0033] Embodiment 4:

[0034] Reference Figure 1 , a photovoltaic power station bird-repelling device, which is basically the same as Example 1, and further, the inner wall of the wind cup 202 is painted with a reflective coating; when the wind cup 202 rotates, the light-emitting coating painted on the inner wall of the wind cup 202 is made of silver. Since silver is an excellent thermal conductor and has high reflectivity, it can reflect sunlight, thereby achieving the effect of repelling birds.
