[0015] According to the above technical solution, the main body of the refrigeration equipment is located below the two sets of fans, and the first arc-shaped plate is located above the second arc-shaped plate.

[0016] Compared with the prior art, the beneficial effects achieved by the present invention are: 1. This energy-efficient solar street light uses a movable component to start the first motor, which rotates the screw. The rotation of the screw causes the screw block to move left and right, which in turn drives the brush roller to move left and right. Since the gear and rack mesh, and the rack is fixed, the left and right movement of the brush roller also causes it to rotate. The rotation of the brush roller can clean the dust on the surface of the solar panel, allowing the solar panel to absorb sunlight to the maximum extent.

[0017] 2. This energy-efficient solar street light, through its sprinkler assembly, utilizes a mechanism where, when the screw block and slider move to the left, the inclined block presses against the connecting frame, causing the connecting frame to move upwards. This upward movement of the connecting frame drives the baffle and the second L-plate upwards, thereby compressing the first spring. Subsequently, rainwater from the water tank is discharged from the sprinkler nozzle and sprayed onto the surface of the solar panel, washing away dust and increasing the light transmittance of the solar panel, further enhancing the solar panel's light absorption and conversion efficiency.

[0018] 3. This energy-efficient solar street light uses a filtration system to allow rainwater to fall into a water tank. The screen inside the tank prevents tree branches from falling into the tank, while the filter plate filters out dust from the rainwater. The filtered rainwater then falls onto the surface of the solar panel, ensuring that the rainwater on the solar panel surface is free of dust.

[0019] 4. This energy-efficient solar street light uses a cooling mechanism to activate the main cooling unit, lowering the temperature inside the rectangular frame. Then, two fans are activated to draw outside air into the rectangular frame. The air inside the frame is then blown onto the surface of the lamp body by the two fans, dissipating heat and reducing the temperature of the electronic components inside the lamp. This reduces thermal decay, extends the lifespan of the lamp body, and ensures continuous and stable illumination, providing ample lighting. Attached Figure Description

[0028] See Figure 6-8Furthermore, based on Example 1, a filtration mechanism 8 was obtained.

A filter plate 82 is provided on the front of the water tank 723. A third fixed frame 83 is fixedly connected to the left side of the water tank 723. A second guide rod 84 is fixedly connected to the third fixed frame 83 from front to back.

[0030] Furthermore, the water tank 723 has a groove on the front that matches the filter plate 82, and the surface of the filter plate 82 is slidably connected to the groove. One end of the second spring 86 is fixedly connected to the side of the third fixed frame 83 near the first hinge frame 85, and the other end of the second spring 86 is fixedly connected to the side of the first hinge frame 85 near the inner side of the third fixed frame 83.

[0031] Furthermore, a groove matching the arc-shaped block 89 is provided on the left side of the water tank 723, and the surface of the arc-shaped block 89 is slidably connected to the groove. Example 3

[0032] See Figure 9-10 Furthermore, based on Embodiment 1, a heat dissipation mechanism 9 is obtained.

[0033] Furthermore, the heat dissipation mechanism 9 includes a fixing plate 91, which is fixedly connected to the surface of the main body rod 2. A rectangular frame 92 is fixedly connected to the left side of the fixing plate 91. A fan 93 is fixedly connected to the inner wall of the rectangular frame 92. A cooling equipment body 94 is fixedly connected to the inner wall of the rectangular frame 92 near the bottom. A first arc-shaped plate 95 is fixedly connected to the top of the fixing plate 91 near the left side. A second arc-shaped plate 96 is fixedly connected to the left side of the rectangular frame 92.

[0034] Furthermore, there are two sets of fans 93, which are fixedly connected to the inner wall of the rectangular frame 92 near the top in a symmetrical manner.

[0035] Furthermore, the main body 94 of the refrigeration equipment is located below the two sets of fans 93, and the first arc plate 95 is located above the second arc plate 96.

[0036] In actual operation, when this device is used, the first motor 714 is started to make the screw 712 rotate. The rotation of the screw 712 will cause the screw block 713 to move left and right, thereby driving the brush roller 718 to move left and right. Since the gear 7112 meshes with the rack 7111 and the rack 7111 is fixed, the left and right movement of the brush roller 718 will also rotate. The rotation of the brush roller 718 can clean the dust on the surface of the solar panel 6, so that the solar panel 6 can absorb sunlight to the maximum extent. When the screw block 713 and slider 717 move to the left, the inclined block 7211 presses against the connecting frame 7212, causing the connecting frame 7212 to move upward. The upward movement of the connecting frame 7212 will drive the baffle 725 and the second L plate 727 to move upward, thereby pressing the first spring 729. Then, the rainwater in the water tank 723 is discharged from the sprinkler nozzle 724 and sprayed onto the surface of the solar panel 6, washing away the dust on the surface of the solar panel 6, increasing the light transmittance of the surface of the solar panel 6, and further increasing the light absorption and conversion efficiency of the solar panel 6. When the screw block 713 and slider 717 drive the inclined block 7211 to move to the right, the inclined block will not contact the connecting frame 7212. At this time, the baffle 725 will move downward due to the elastic force of the first spring 729, so that the rainwater will not be discharged from the water tank 723. Rainwater falls into the water tank 723, and the baffle 81 inside the water tank 723 can prevent tree branches from falling into the water tank 723. The filter plate 82 inside the water tank 723 can filter the dust in the rainwater. The filtered rainwater is sprayed onto the surface of the solar panel 6, so that the rainwater sprayed onto the surface of the solar panel 6 does not contain dust. When the filter plate 82 needs to be replaced, the filter plate 82 is pulled out from the box, and then the new filter plate 82 is slid into the box. At this time, the arc block 89 will move to the right by the elastic force of the second spring 86 and drive into the arc groove 811 on the left side of the filter plate 82, limiting the filter plate 82 and fixing the filter plate 82 inside the water tank 723. The main body of the cooling equipment 94 is started to lower the temperature inside the rectangular frame 92. Then, two fans 93 are started to draw outside air into the rectangular frame 92. The air inside the rectangular frame 92 will then be blown to the surface of the lamp body 4 by the operation of the two fans 93 to dissipate heat from the lamp body 4, reduce the temperature of the electronic components inside the lamp body 4, thereby reducing thermal decay, extending the service life of the lamp body 4, and ensuring that the lamp body 4 emits light continuously and stably, providing sufficient illumination.
