[0031] The present invention is further described in detail below with reference to the accompanying drawings and specific embodiments:

[0032] See also Figure 1A photovoltaic bracket with adjustable angle that is easy to clean and install includes a frame-type base 10, an angle adjustment mechanism 20 arranged in the base 10, and a mounting mechanism 30 arranged above the base 10 for fixing a photovoltaic panel 50. In this embodiment, the frame-type base 10 adopts a U-shaped frame with one side open, which can also be replaced by a square frame. The angle adjustment mechanism 20 is fixedly connected to the base 10 and hinged to the mounting mechanism 30. The mounting mechanism 30 is also rotatably connected to the base 10. Under the push of the angle adjustment mechanism 20, the mounting mechanism 30 rotates up and down around the axis of rotation, using the axis of rotationally connecting the mounting mechanism 30 and the base 10 as the axis, to achieve angle adjustment of the mounting mechanism 30.

[0033] See also Figure 1 and Figure 2 The angle adjustment mechanism 20 includes an electric push rod 21, a push plate 22, at least two support rods 23 and at least one guide rod 24. The electric push rod 21 and the guide rod 24 are both fixedly connected to the base 10 and are arranged horizontally and parallel to each other. The push plate 22 is fixed to the movable end of the electric push rod 21 and is perpendicular to the electric push rod 21. The guide rod 24 passes through the push plate 22, and the guide rod 24 is slidably connected to the push plate 22. One end of the support rod 23 is hinged to the push plate 22, and the other end is hinged to the mounting mechanism 30. The angle adjustment mechanism 20 changes the angle between the support rod 23 and the mounting mechanism 30 when the electric push rod 21 drives the push plate 22 to slide horizontally, so that the mounting mechanism 30 rotates up and down around the rotating shaft, thereby realizing the angle adjustment of the mounting mechanism 30. During the angle adjustment process, since the electric push rod 21 is fixed on the base 10, the push plate 22 is slidably connected to the guide rod 24, and the guide rod 24 is also fixed on the base 10, therefore, the electric push rod 21 in this embodiment does not need to bear the gravity of the photovoltaic panel 50 and the mounting mechanism 30, and only needs to apply horizontal thrust or pulling force to the push plate 22, which not only saves labor but also makes the electric push rod 21 not easily damaged, thereby extending the service life of the entire equipment and reducing equipment maintenance costs.

[0034] See also Figures 3 to 5, the mounting mechanism 30 includes a mounting frame 31 for supporting a photovoltaic panel 50, a pressure plate 32 disposed above the photovoltaic panel 50, a first fixing component 33 and a second fixing component 34. One side of the mounting frame 31 is rotatably connected to the base 10, the first side 321 of the pressure plate 32 is rotatably connected to the mounting frame 31 through the first fixing component 33, and the second side 322 of the pressure plate 32 that is disposed opposite to the first side 321 is detachably connected to the mounting frame 31 through the second fixing component 34. Exemplarily, the pressure plate 32 can be a frame-type pressure plate. The first fixing component 33 includes at least two columns 331, a horizontally disposed transverse pressure rod 332, a first elastic member 333 sleeved on the column 331, and a limiting cross bar 334 fixed above the column 331. The columns 331 are vertically fixed to the side of the mounting frame 31, and each of the columns 331 passes through the transverse pressure rod 332. The transverse pressure rod 332 is movably sleeved on the columns 331. The first elastic member 333 is sleeved between the transverse pressure rod 332 and the limiting cross bar 334. The first side 321 of the pressing plate 32 is arranged between the transverse pressure rod 332 and the mounting frame 31. In this embodiment, the limiting cross bar 334 is integrally formed with the mounting frame 31. The first side 321 of the pressing plate 32 is provided with a connecting groove 3211 matching the shape of the lower bottom of the transverse pressure rod 332. Preferably, the lower bottom of the transverse pressure rod 332 is an arc-shaped bottom, and the connecting groove 3211 is an arc-shaped groove, so that the frame-shaped pressure plate 32 can be opened by rotation to put the photovoltaic panel 50, or the frame-shaped pressure plate 32 can be removed by lifting the transverse pressure rod 332, and the photovoltaic panel 50 can be put into the installation frame 31, and then the transverse pressure rod 332 is lifted again, and the pressure plate 32 is pressed by the elasticity of the first elastic member 333. The second fixing component 34 is at least one buckle. Preferably, the buckle is a spring-pressed rotary buckle, which includes a connecting rod 341, a second elastic member 342 sleeved on the connecting rod 341, and a rotating handle 343 and a positioning plate 344 respectively arranged at both ends of the connecting rod 341, the connecting rod 341 is inserted through the second side edge 322 of the pressing plate 32, the second elastic member 342 is arranged between the pressing plate 32 and the rotating handle 343, the rotating handle 343 and the positioning plate 344 are arranged alternately up and down, and the positioning plate 344 abuts against the lower bottom surface of the mounting frame 31. When the first side edge 321 of the pressing plate 32 is fixed by the first fixing assembly 33, at the second side edge 322 of the pressing plate 32, by pressing down and rotating the rotating handle 343, the positioning plate 344 abuts against the mounting frame 31, and is pressed against the mounting frame 31 by the elastic force of the second elastic member 342.

[0035] The photovoltaic panel 50 is installed by the installation mechanism 30 of this embodiment without the need for fasteners such as bolts or installation tools. The installation process is simple, the disassembly is convenient, and the photovoltaic panel 50 can be installed repeatedly, thereby improving work efficiency.

[0036] Preferably, see Figures 6 to 8 , the photovoltaic support of this embodiment also includes a cleaning mechanism 40, which spans above the mounting frame 31. The cleaning mechanism 40 includes a row frame 41, a scraper 43 fixed below the row frame 41 through two connecting components 42, a guide wheel 44 and a drive motor 45 respectively fixed at both ends of the row frame 41, and a drive wheel 46 connected to the drive motor 45. In this embodiment, the row frame 41 is a U-shaped frame. The lower edge of the scraper 43 contacts the photovoltaic panel 50, the connecting components 42 are respectively arranged at both ends of the scraper 43, the side of the mounting frame 31 is provided with a guide groove 311 for embedding the guide wheel 44, the guide wheel 44 slides in the guide groove 311, the drive wheel 46 abuts against the upper surface of the mounting frame 31, and the scraper 43 is located above the photovoltaic panel 50 and contacts the photovoltaic panel 50. The driving motor 45 drives the driving wheel 46 to rotate, and the guide wheel 44 cooperates with the guide groove 311 to ensure that the travel path of the frame 41 will not deviate. The scraper 43 scrapes away dust and other dirt on the photovoltaic panel 50 during the movement to clean the surface of the photovoltaic panel 50. In order to clean the dirt on the scraper 43, the present embodiment is further provided with a high-pressure jet mechanism to blow away the dirt on the scraper 43 with high-pressure gas. Specifically, the travel frame 41 includes a hollow high-pressure transverse pipe 411, two connecting seats 412 and an air intake connecting column 413. The bottom surface of the high-pressure transverse pipe 411 is provided with an air jet. The two ends of the high-pressure transverse pipe 411 are respectively fixed with a connecting seat 412. The air intake connecting column 413 is arranged on the outer side of one of the connecting seats 412 and is connected with the inner cavity of the high-pressure transverse pipe 411. The connecting assembly 42 is fixedly connected to the high-pressure transverse pipe 411 and the scraper 43. The guide wheel 44 and the driving motor 45 are both fixed to the inner side of the connecting seat 412. When the cleaning mechanism 40 moves to the edge of the mounting frame 31, high-pressure gas is filled into the high-pressure transverse pipe 411 through the air intake connecting column 413, and then the high-pressure gas is ejected through the air jet to blow away dust and other dirt, so as to achieve the cleaning function.

[0037] When the scraper 43 reaches the bottom and completes the cleaning of the photovoltaic panel 50, in order to prevent the cleaning mechanism 40 from affecting the photovoltaic panel 50 in absorbing solar energy, the cleaning mechanism 40 needs to be moved to the edge of the mounting frame 31. At this time, the scraper 43 must be lifted up a little due to the squeezing of the mounting frame 31 and the connecting pin 423. Therefore, a connecting assembly 42 is provided to meet the up and down movement of the scraper 43. The connecting assembly 42 includes a fixed rod 421 with a movable groove, a third elastic member 422 and a connecting pin 423. The fixed rod 421 is vertically fixed to the lower bottom surface of the high-pressure cross pipe 411. One end of the connecting pin 423 is fixedly connected to the scraper 43, and the other end is embedded in the movable groove. One end of the third elastic member 422 is fixedly connected to the lower bottom surface of the frame 41, and the other end is fixedly connected to the connecting pin 423. When the scraper 43 is stressed and needs to be lifted up, the scraper 43 drives the connecting pin 423 to move upward, and the outer end of the connecting pin 423 moves upward in the movable groove of the fixing rod 421. The third elastic member 422 can ensure that the scraper 43 returns to its original position and keeps in contact with the photovoltaic panel 50 when it starts cleaning.

[0038] The present invention discloses a photovoltaic bracket that is easy to clean and install and has an adjustable angle. The main component of the angle adjustment mechanism 20, the electric push rod 21, is horizontally arranged, which greatly reduces the load borne by the electric push rod 21, prolongs the service life of the electric push rod 21, and reduces the maintenance cost of the photovoltaic bracket. At the same time, the mounting frame 31 and the pressure plate 32 of the photovoltaic bracket of the present invention are installed and fixed by the first fixing component 33 and the second fixing component 34. Compared with the traditional photovoltaic bracket, the structure of fixing the photovoltaic panel is simplified, more springs are used, and the use of bolts is reduced. At the same time, the installation and disassembly is more convenient, simple and reusable. In addition, the photovoltaic bracket of the present invention is also provided with a cleaning mechanism 40, which is integrated with the installation mechanism 30. It is not only simple in structure, low in energy consumption, and easy to install, but also has a strong cleaning power on the photovoltaic panel 50.
