Its protection effect is also relatively simple, and it is necessary to cover the photovoltaic panels with transparent shielding, and use the anti-ultraviolet effect of the transparent shielding to reduce the aging effect of ultraviolet rays on the photovoltaic panels.

[0003] In the prior art, shielding objects are generally fixedly installed directly on photovoltaic panels. Whenever the shielding objects are not needed, the staff will store them and manually install them when needed. The steps are very cumbersome and physically demanding. Utility Model Content

[0004] The utility model aims at solving the problems in the prior art and proposes the following technical solutions:

[0005] A photovoltaic panel protection device includes a photovoltaic component and a protection mechanism for shielding and protecting the photovoltaic component, the protection mechanism includes two mirror-set transmission shafts, the two transmission shafts are connected by a connecting plate, the photovoltaic component is installed between the two connecting plates, and the outer rings at both ends of the transmission shaft are fixedly sleeved with pulleys, the two pulleys located at the same end are connected by belt transmission, and a transparent protection layer for shielding sunlight is fixedly connected in the middle of the two belts, the transparent protection layer is made of a PET film, the length and width of the transparent protection layer are both greater than the length and width of the photovoltaic panel body, and a cleaning sponge is installed on the side of the transparent protection layer close to the photovoltaic panel body.

[0006] When the transparent protective layer is completely located below the photovoltaic module, the photovoltaic module will receive sunlight without obstruction to generate electricity. When the transparent protective layer is completely located above the photovoltaic module, the transparent protective layer will completely block the photovoltaic module. The film made of PET has the functions of good light transmittance and UV protection, thereby reducing the aging of photovoltaic modules caused by ultraviolet rays and increasing their service life.

[0007] As a preferred embodiment of the above technical solution, the photovoltaic assembly includes a photovoltaic panel body, a detachable pipe groove is installed on one side of the photovoltaic panel body, both ends of the pipe groove are fixedly connected with wind collecting hoods, a mounting seat is welded on the inner side of the connecting plate, the mounting seat is connected to the frame of the photovoltaic panel body by bolts, and the bottom of the cleaning sponge is in contact with the upper surface of the photovoltaic panel body.

[0008] After the flowing air enters the pipe groove through the wind collecting hood, its flow rate is increased compared with the flow rate outside the pipe groove. When the transparent protective layer drives the cleaning sponge to move from front to back, the cleaning sponge will hang the foreign matter attached to the upper surface of the photovoltaic panel body into the inside of the pipe groove to prevent it from falling directly onto the transparent protective layer, thereby avoiding affecting the light transmittance of the transparent protective layer.

[0009] As a preferred embodiment of the above technical solution, a rocker arm is fixedly connected to one end of the transmission shaft, a handle is provided on the inner ring movable sleeve of the rocker arm, and a positioning component for limiting the displacement of the handle is installed on the outer side of the connecting plate.

[0010] The two mirror-image transmission shafts are connected by pulleys and belt drives, so that when the handle and the rocker arm are shaken, the two transmission shafts will rotate synchronously, and the transparent protective layer installed between the two belts will also move synchronously.

[0011] As a preferred embodiment of the above technical solution, the outer ring fixing sleeve of the handle is provided with baffles respectively located on both sides of the rocker arm, and the outer ring diameter of the baffles is larger than the inner ring diameter of the rocker arm.

[0012] The baffles on both sides of the rocker arm can prevent the handle from being separated from the rocker arm, making it convenient for employees to shake the handle to drive the transmission shaft connected to it to rotate through the rocker arm.

[0013] As a preferred embodiment of the above technical solution, the positioning assembly includes a positioning sleeve fixed on the outer wall of the connecting plate, and the tail end of the handle is plugged into the positioning sleeve.

[0014] Through the insertion of the positioning sleeve and the handle, if the handle needs to be shaken, it needs to be separated from the positioning sleeve.

[0015] As a preferred embodiment of the above technical solution, a second magnet is fixedly mounted on the inner wall of the positioning sleeve, and a first magnet is fixedly mounted on the tail end of the handle, and the first magnet and the second magnet are attracted to each other by opposite polarities.

[0016] The magnetic attraction between the first magnet and the second magnet ensures that the handle cannot be separated from the positioning sleeve without any external force.

[0017] The beneficial effects of the utility model are:

[0018] 1: When the handle and the rocker arm are shaken, the two transmission shafts will rotate synchronously, and the transparent protective layer installed between the two belts will also move synchronously. When the transparent protective layer is completely moved above the photovoltaic panel body, the transparent protective layer will cover the photovoltaic panel body. The transparent protective layer made of PET can reduce the aging of the photovoltaic components caused by ultraviolet rays and increase the service life;

[0019] 2: When the photovoltaic panel body needs to generate electricity, the removal of the transparent protective layer will drive the cleaning sponge to clean the foreign matter on the surface of the photovoltaic panel body. The cleaned foreign matter will fall into the inside of the pipe groove. Finally, the air flow rate into the pipe groove will be increased through the wind collecting cover, and the foreign matter will be blown out, thereby improving the power generation efficiency of the photovoltaic panel body;

[0020] 3: Through the magnetic attraction of magnet 1 and magnet 2, the movement of the transparent protective layer requires manually pulling the handle until the handle is completely separated from the positioning sleeve, which can prevent the transparent protective layer from shifting again after the position is determined, thereby ensuring the stability of the position of the transparent protective layer.

Figure 4 What is shown is the enlarged structural schematic diagram of point A of the present utility model.

[0028] A photovoltaic panel protection device includes a photovoltaic module 100 and a protection mechanism 200 for shielding and protecting the photovoltaic module 100, the protection mechanism 200 includes two mirror-image transmission shafts 201, the two transmission shafts 201 are connected by a connecting plate 203, the photovoltaic module 100 is installed between the two connecting plates 203, and the outer rings at both ends of the transmission shaft 201 are fixedly sleeved with pulleys 202, the two pulleys 202 located at the same end are connected by a belt 205, and a transparent protection layer 206 for shielding sunlight is fixedly connected in the middle of the two belts 205, the transparent protection layer 206 is made of a PET film, the length and width of the transparent protection layer 206 are both greater than the length and width of the photovoltaic panel body 101, and a cleaning sponge 207 is installed on the side of the transparent protection layer 206 close to the photovoltaic panel body 101.

[0029] When the transparent protective layer 206 is completely located below the photovoltaic module 100, the photovoltaic module 100 will receive sunlight without any obstruction to generate electricity. When the transparent protective layer 206 is completely located above the photovoltaic module 100, the transparent protective layer 206 will completely block the photovoltaic module 100. The transparent protective layer 206 is made of PET film with good light transmittance and UV protection, thereby reducing the aging of the photovoltaic module 100 caused by ultraviolet rays and increasing its service life.

[0030] Figure 1 , Figure 2 and Figure 3 It shows Figure 1 What is shown is the overall structural diagram of the utility model, Figure 2 The structure diagram of the photovoltaic module 100 of the utility model is shown. Figure 3 Shown is a schematic structural diagram of a protection mechanism 200 of the present invention.

[0031] The photovoltaic assembly 100 includes a photovoltaic panel body 101, a detachable pipe groove 102 is installed on one side of the photovoltaic panel body 101, both ends of the pipe groove 102 are fixedly connected with a wind collecting hood 103, a mounting seat 204 is welded on the inner side of the connecting plate 203, the mounting seat 204 is connected to the frame of the photovoltaic panel body 101 by bolts, the bottom of the cleaning sponge 207 is in contact with the upper surface of the photovoltaic panel body 101, one end of the transmission shaft 201 is fixedly connected with a rocker arm 208, the inner ring movable sleeve of the rocker arm 208 is provided with a handle 209, and the outer side of the connecting plate 203 is installed with a positioning component for limiting the displacement of the handle 209.

[0032] The two mirror-image transmission shafts 201 and the connecting plate 203 connecting them form a "mouth"-shaped space. The two pulleys 202 on the same side are connected by a belt 205. Therefore, when the handle 209 and the rocker arm 208 installed on the transmission shaft 201 are shaken, the two transmission shafts 201 will rotate synchronously, and the transparent protective layer 206 installed between the two belts 205 will also move synchronously. When the transparent protective layer 206 drives the cleaning sponge 207 to move from front to back, the cleaning sponge 207 will Foreign objects on the upper surface of the panel body 101 are hung and fall into the interior of the tube groove 102 to prevent them from falling directly onto the transparent protective layer 206. After the flowing air enters the tube groove 102, its flow rate is increased compared to the flow rate outside the tube groove 102 through the wind collecting cover 103, thereby directly blowing out foreign objects that fall into the tube groove 102. At the same time, since the tube groove 102 is detachable, when the appearance of the tube groove 102 and the wind collecting cover 103 is deformed or rusted, it is convenient to remove them from the frame of the photovoltaic panel body 101 for maintenance and replacement.

[0033] Figure 1 , Figure 3 and Figure 4 It shows Figure 1 What is shown is the overall structural diagram of the utility model, Figure 3 The figure shows a schematic diagram of the structure of the protection mechanism 200 of the utility model. Figure 4 What is shown is the enlarged structural schematic diagram of point A of the present utility model.

[0034] The outer ring fixed sleeve of the handle 209 is provided with baffles 210 respectively located on both sides of the rocker arm 208, the outer ring diameter of the baffle 210 is larger than the inner ring diameter of the rocker arm 208, the positioning assembly includes a positioning sleeve 212 fixed on the outer wall of the connecting plate 203, the tail end of the handle 209 is plugged into the positioning sleeve 212, the inner wall of the positioning sleeve 212 is fixedly installed with a magnet 213, and the tail end of the handle 209 is fixedly installed with a magnet 1 211, and the magnet 1 211 and the magnet 2 213 are attracted to each other by opposite poles.

[0035] Since the positioning sleeve 212 is inserted into the handle 209, if you want to shake the handle 209, you need to separate it from the positioning sleeve 212. However, the magnetic attraction of magnet 1 211 and magnet 2 213 makes it impossible for the handle 209 to be separated from the positioning sleeve 212 without any external force. The handle 209 can only be shaken by manually pulling the handle 209 until the handle 209 is completely separated from the positioning sleeve 212. Since the outer ring diameter of the baffle 210 located on both sides of the rocker arm 208 is larger than the inner ring diameter of the rocker arm 208, the setting of the baffle 210 can limit the separation of the handle 209 from the rocker arm 208, making it convenient for employees to shake the handle 209 and drive the transmission shaft 201 connected to it to rotate through the rocker arm 208.

[0036] The above embodiments are only used to illustrate the technical solution of the present invention, but not to limit it.
