[0031] As shown in the accompanying drawings, a specific embodiment of the present invention is a windproof photovoltaic power generation device for construction engineering, including a photovoltaic panel 2, a mounting bracket 1 and a cleaning component;

[0032] The photovoltaic panel 2 can be detachably mounted on the mounting bracket 1;

[0033] The cleaning component is installed on the mounting bracket 1, and the cleaning component includes a driving mechanism and a cleaning mechanism. The driving mechanism is transmission-connected with the cleaning mechanism. The natural wind drives the driving mechanism to operate and then drives the cleaning mechanism to clean the surface of the photovoltaic panel 2.

[0034] In the above scheme, by setting up a cleaning component, the natural wind is used to drive the driving mechanism to run and then drive the cleaning mechanism to clean the surface of the photovoltaic panel, which effectively reduces the manual labor. At the same time, the driving mechanism can also effectively reduce the wind speed passing through the surface of the photovoltaic panel, and play a certain wind-proof effect.

[0035] The driving mechanism includes a rotating shaft 6 and a plurality of blades 5, wherein the rotating shaft 6 is vertically rotatably mounted on the mounting bracket 1, and the plurality of blades 5 are spaced apart on the rotating shaft 6, and the driving mechanism can rotate around the rotating shaft 6 driven by the natural wind. The blades and the rotating shaft can effectively eliminate a portion of the energy of the wind passing through the photovoltaic panel during the rotation process, reduce the wind speed, and thus achieve a certain windproof effect.

[0036] Specifically, the cleaning mechanism includes a mounting plate 4 and a brush 3, wherein the mounting plate 4 is arranged at the lower end of one of the blades 5, and the brush 3 is arranged on the mounting plate 4, and the lower end surface of the brush 3 contacts the upper end surface of the photovoltaic panel 2.

[0037] Furthermore, in order to prevent the blades from blocking sunlight and affecting the power generation efficiency of the photovoltaic panel, the blades 5 are made of light-transmitting material. The blades made of light-transmitting material can ensure that sunlight can be smoothly irradiated on the photovoltaic panel.

[0038] In order to prevent the brush from damaging the photovoltaic panel during the cleaning process, a transparent protective film is provided on the upper surface of the photovoltaic panel 2, and the protective film can provide a good protection for the photovoltaic panel.

[0039] As another embodiment of the present invention, the cleaning component also includes a rainwater collecting mechanism and a spraying mechanism, both of which are installed on the mounting bracket 1, the rainwater collecting mechanism is used to collect rainwater, the spraying mechanism is connected to the rainwater collecting mechanism, and the spraying mechanism is used to spray the rainwater collected in the rainwater collecting mechanism onto the surface of the photovoltaic panel 2 for cleaning.

[0040] Furthermore, the rainwater collection mechanism includes a collection box 7 and a connecting pipe 10, and an annular protrusion 8 is provided at the edge of the photovoltaic panel 2. One end of the connecting pipe 10 is installed in the annular protrusion 8, and the other end is connected to the collection box 7 installed on the mounting bracket 1. Furthermore, the spray mechanism includes a spray head 9 and a piston pump. The spray head 9 is installed at the upper end of the photovoltaic panel 2. The piston pump is connected to the driving assembly in a transmission manner. The piston pump is used to extract rainwater in the collection box 7 and transport it to the spray head 9 to spray it out to clean the surface of the photovoltaic panel 2. Among them, by providing an annular protrusion, rainwater can be retained on the photovoltaic panel when it rains, and the rainwater retained on the photovoltaic panel flows into the collection box through the connecting pipe on the annular protrusion for storage.

[0041] In this embodiment, specifically, the piston pump includes a pump body 14, a piston head 15, a spring 17 and a piston rod 12, the pump body 14 is installed in the collection box 7, a piston cavity 21 that cooperates with the piston head 15 is provided in the pump body 14, one end of the piston rod 12 is connected to the piston head 15, and the other end extends out of the body, a limiting ring 18 is provided on the piston rod 12, a limiting ring 2 16 is provided in the piston cavity 21, and the spring 17 is sleeved on the piston rod The piston rod 12 is on the upper surface of the pump body 14 and one end thereof abuts against the limit ring 18, and the other end abuts against the limit ring 2 16. The end of the piston rod 12 away from the pump body 14 is provided with a section of transmission tooth 1 20. The lower end of the rotating shaft 6 is provided with a transmission plate 11, and the transmission plate 11 is provided with a section of transmission tooth 2 19 meshing with the transmission tooth 1 20. The transmission plate 11 is a one-way transmission, that is, when the rotating shaft rotates clockwise, the transmission plate rotates with the rotating shaft, and when the rotating shaft rotates counterclockwise, the rotating plate does not rotate with the rotating shaft.

[0042] The pump body 14 is provided with a liquid inlet pipe 13 and a liquid outlet pipe 23 connected with the piston chamber 21, a check valve 1 22 is provided in the liquid inlet pipe 13, a check valve 2 24 is provided in the liquid outlet pipe 23, and the liquid outlet pipe 23 is connected with the sprinkler head 9.

[0043] In the above scheme, specifically, when the natural wind drives the shaft to rotate, the brush under the blades rotates with the blades, thereby scraping the surface of the photovoltaic panel, cleaning up impurities on the surface of the photovoltaic panel, and improving the power generation efficiency of the photovoltaic panel; at the same time, when the shaft rotates clockwise, the shaft drives the transmission disc to rotate, and when the transmission disc rotates to the point where the transmission tooth 2 on the transmission disc can engage with the transmission tooth 1, the transmission disc drives the piston rod to move, and then the piston head presses the rainwater in the piston chamber into the liquid outlet pipe and sprays it from the spray head to the photovoltaic surface. With the scraping of the brush, the surface of the photovoltaic panel can be cleaned more cleanly. During the rotation of the transmission disc, after the transmission tooth 2 disengages from the transmission tooth 1, the piston rod drives the piston head under the action of the spring to pump the rainwater in the collection chamber into the piston chamber 2. As a result, the shaft can drive the piston pump to spray the rainwater in the collection chamber from the spray head at intervals during the rotation.

The present invention is not limited to the above embodiments, and its specific structure is allowed to be changed. All changes made within the scope of protection of the independent claims of the present invention are within the scope of protection of the present invention.
