[0043] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0044] See also Figure 1-14 The present invention provides a technical solution: a photovoltaic bracket fixing device, which is arranged at the upper end of a prefabricated pipe pile 1 and is used to install a photovoltaic panel 3, comprising:

[0045] A fixing part is arranged on the prefabricated pipe pile 1;

[0046] A supporting member, arranged on the fixing member;

[0047] A fixing mechanism 26, which is arranged on the support and located above the prefabricated pipe pile 1, and is used to fix the photovoltaic panel 3;

[0048] The cleaning device 4 is arranged on one side of the fixing mechanism 26 and located above the photovoltaic panel 3 , and is used for cleaning the photovoltaic panel 3 .

[0049] It should be noted that, during operation, when installing the photovoltaic panel 3, first fix the fixing part on the prefabricated pipe pile 1, then fix the support part on the fixing part, then install the fixing mechanism 26 on the upper end of the support part, and adjust the installation angle of the fixing mechanism 26. After the adjustment is completed, fix the fixing mechanism 26 and the support part, and then fix the photovoltaic panel 3 on the fixing mechanism 26 to complete the fixing work of the photovoltaic panel 3. The photovoltaic panel 3 is cleaned by the cleaning device 4 to maintain the cleanliness of the upper end of the photovoltaic panel 3, thereby improving the power generation efficiency of the photovoltaic panel 3. The present invention fixes the fixing part on the prefabricated pipe pile 1 detachably, and then fixes and supports the photovoltaic panel 3 by the support part and the fixing mechanism 26, so that the photovoltaic panel 3 is more stably and reliably installed on the fixing mechanism 26, and the installation process is simple and quick, which greatly improves the installation efficiency. A cleaning device 4 is set on one side of the fixing mechanism 26 to remove dust, debris, etc. on the surface of the photovoltaic panel 3, thereby maintaining the cleanliness of the photovoltaic panel 3 and improving its power generation efficiency.

[0050] In one embodiment, the fixing member includes a first clamp 21 detachably fixed to the prefabricated pipe pile 1 and a second clamp 23 detachably fixed to the prefabricated pipe pile 1 and located above the first clamp 21 , and the supporting member is fixed to the first clamp 21 and the second clamp 23 .

[0051] This design, see Figure 2 ,as well as Fig.12 The first clamp 21 and the second clamp 23 are respectively fixed at different heights of the prefabricated pipe pile 1 to form a stable support structure. This double clamp design can more effectively disperse and bear the weight and wind force generated by the photovoltaic panel 3 and its bracket, and significantly enhance the stability and reliability of the entire photovoltaic bracket system. The clamp can quickly and easily install the support and photovoltaic panel 3 on the prefabricated pipe pile 1, and is also convenient for subsequent disassembly and maintenance.

[0052] In one embodiment, the support member includes a rear column 22 fixed on one side of the first clamp 21 and the second clamp 23, a front column 24 arranged on one side of the first clamp 21 and the second clamp 23, a rear diagonal brace 28 fixed on the side of the first clamp 21 close to the rear column 22, and a front diagonal brace 27 fixed on the side of the first clamp 21 close to the front column 24. The rear column 22 and the front column 24 are symmetrically arranged with respect to the prefabricated pipe pile 1, and an abutment plate 25 fixed to the prefabricated pipe pile 1 is arranged at the position of the rear column 22 and the front column 24 located at the upper end of the prefabricated pipe pile 1.

[0053] This design, see Figure 2 ,as well as Fig.12, The rear column 22 and the front column 24 are respectively fixed to one side of the first hoop 21 and the second hoop 23, forming a solid vertical support structure. This not only enhances the bearing capacity of the support member but also improves the structural strength and stability of the entire photovoltaic support system. The addition of the front diagonal brace 27 and the rear diagonal brace 28 further constitutes a stable triangular support structure, effectively dispersing the weight of the photovoltaic panel 3 and its support, as well as external loads such as wind force, and enhancing the wind pressure resistance and anti-overturning ability of the system. The setting of the abutting plate 25 enables the support member to be more firmly fixed on the precast pipe pile 1, and at the same time facilitates the adjustment and positioning during the installation process. The modular design of the rear column 22, the front column 24, the front diagonal brace 27, and the rear diagonal brace 28 allows the support member to be flexibly combined and adjusted according to actual needs to adapt to photovoltaic panels 3 of different sizes and shapes and different installation environments.

[0054] In one embodiment, the fixing mechanism 26 includes a crossbeam 261 that is inclined and bolted to the upper ends of the rear column 22, the front column 24, the front diagonal brace 27, and the rear diagonal brace 28, purlins 262 that are spaced apart at the upper end of the crossbeam 261, and purlin brackets 263 that are fixed on the crossbeam 261 for fixing the purlins 262. A pressing block 264 is detachably fixed to the upper end of the purlin 262. The pressing block 264 is in an inverted "L" shape and abuts against the photovoltaic panel 3 for fixing the photovoltaic panel 3. The crossbeam 261 is inclined.

[0055] With this design, referring to Figure 2-3 and Fig.12 , place the photovoltaic panel 3 on the purlin 262, then fix the pressing block 264 between two photovoltaic panels 3, and then fix the pressing block 264 to the purlin 262 with bolts. Setting multiple pressing blocks 264 on the purlin 262 can improve the stability of the fixation of the photovoltaic panel 3. The purlins 262 are spaced apart at the upper end of the crossbeam 261 and fixed by purlin brackets 263. This design makes the installation and disassembly of the photovoltaic panel 3 more convenient. The pressing block 264 is designed in an inverted "L" shape, abuts against and fixes the photovoltaic panel 3, which not only simplifies the installation process but also improves the firmness of the installation. The crossbeam 261 is inclined, enabling the inclined installation of the photovoltaic panel 3, which is convenient for the photovoltaic panel 3 to receive light. This allows the fixing mechanism 26 to adapt to photovoltaic panels 3 of different specifications and weights and improves the power generation efficiency of the photovoltaic panel 3.

[0056] In one embodiment, a side plate 265 is fixed to one side of the purlin 262, and the cleaning device 4 includes a movable plate 411 slidably arranged on the side of the side plate 265 away from the photovoltaic panel 3, a motor 41 fixed on the movable plate 411, a rotating shaft 42 fixed at the power output end of the motor 41, a transmission mechanism arranged on the rotating shaft 42, and an electromagnetic plate 45 arranged at a position where the rotating shaft 42 is located above the photovoltaic panel 3, and a supporting mechanism 266 is arranged between the purlin 262 and the photovoltaic panel 3, and the supporting mechanism 266 is electrically connected to the electromagnetic plate 45 through a plc control element.

[0057] This design, see Figure 7 The support mechanism 266 is electrically connected to the electromagnetic plate 45 through the PLC control element, realizing intelligent control of the cleaning process. When the surface of the photovoltaic panel 3 needs to be cleaned, the PLC control element can automatically start the motor 41 to drive the cleaning device 4 to work. The cleaning device 4 drives the rotating shaft 42 through the motor 41, thereby driving the transmission mechanism and the electromagnetic plate 45 to move, thereby realizing automatic cleaning of the surface of the photovoltaic panel 3. The photovoltaic panel 3 is cleaned by electrostatic repulsion. Driven by the rotating shaft 42, the electromagnetic plate 45 can be accurately positioned above the photovoltaic panel 3. The electromagnetic plate 45 consists of an electrode and an ultra-thin transparent film containing aluminum-doped zinc oxide. When the photovoltaic panel 3 needs to be cleaned, an electric charge will be applied to the electrode to generate an electric field to charge the dust particles. Then, an opposite charge is applied to the film to repel the particles on the film, causing them to jump off, and the dust attached to the photovoltaic panel 3 is cleaned.

[0058] In one embodiment, the support mechanism 266 includes a fixed plate 2661 fixed to the upper end of the purlin 262, a support plate 2663 fixed to the upper end of the fixed plate 2661 and connected to the photovoltaic panel 3, and a pressure sensor 2662 arranged between the fixed plate 2661 and the support plate 2663. The support plate 2663 is L-shaped, and the pressure sensor 2662 is electrically connected to the electromagnetic plate 45 through a plc control element.

[0059] This design, see Figure 7 ,as well as Figure 8The support mechanism 266 is firmly fixed on the purlin 262 through the fixing plate 2661, providing a stable support for the photovoltaic panel 3. The L-shaped support plate 2663 not only enhances the stability of the support, but also ensures a firm connection between the photovoltaic panel 3 and the bracket, thereby improving the safety of the entire photovoltaic system. The setting of the pressure sensor 2662 enables the support mechanism 266 to monitor the pressure changes on the photovoltaic panel 3 in real time. When the pressure sensor 2662 detects that the pressure changes due to the accumulation of dirt on the surface of the photovoltaic panel 3, the pressure sensor 2662 will immediately send a signal to the electromagnetic plate 45 and the motor 41 through the PLC control element, triggering the electromagnetic plate 45 to be energized and driving the motor 41 to move, so as to clean the upper end of the photovoltaic panel 3. This automated cleaning method not only improves the cleaning efficiency, but also reduces the cost and risk of manual intervention.

[0060] In one embodiment, the transmission mechanism includes a first gear 43 fixed on the rotating shaft 42 and a rack 44 fixed on the side plate 265, the first gear 43 is meshedly connected with the rack 44, and a first moving groove 26502 for the first gear 43 to move is opened on the side plate 265;

[0061] A slider 412 is provided on one side of the movable plate 411 connected to the side plate 265, and a slide groove 26501 is provided on the side plate 265 for the slider 412 to move;

[0062] The rack 44 is fixed in the first moving groove 26502;

[0063] A protection frame 46 for protecting the transmission mechanism is disposed on both sides of the side plate 265, and a second moving groove 4601 for the rotating shaft 42 to move is opened on the protection frame 46;

[0064] A stabilizing plate 452 is provided on one side where the electromagnetic plate 45 is connected to the protective frame 46. The stabilizing plate 452 is slidably connected to the protective frame 46. A stabilizing groove 4602 is provided on the protective frame 46 for the stabilizing plate 452 to move.

[0065] A connecting wire 451 is provided on the electromagnetic plate 45 .

[0066] This design, see Figure 6 ,as well as Fig.13The meshing connection between the first gear 43 and the rack 44 constitutes the core of the transmission mechanism, ensuring the high efficiency and stability of the transmission. When the motor 41 drives the rotating shaft 42 to rotate, the first gear 43 rotates accordingly and interacts with the rack 44, thereby driving the entire cleaning device 4 to move along the side plate 265. The moving plate 411 is connected to the sliding groove 26501 on the side plate 265 through the slider 412. This design enables the moving plate 411 to move flexibly on the side plate 265 while ensuring the accuracy of the movement. The opening of the first moving groove 26502 provides space for the movement of the first gear 43, ensuring the smooth operation of the transmission mechanism. The setting of the protective frame 46 provides comprehensive protection for the transmission mechanism, prevents the invasion of external impurities and dust, and extends the service life of the transmission mechanism. The opening of the second movable groove 4601 provides necessary space for the movement of the rotating shaft 42, while ensuring the stability of the protective frame 46. The sliding connection between the stabilizing plate 452 and the protective frame 46 provides a stable support for the electromagnetic plate 45, while ensuring the smoothness of the electromagnetic plate 45 during the movement. The opening of the stabilizing groove 4602 provides a guide for the movement of the stabilizing plate 452, ensuring the stability and accuracy of the electromagnetic plate 45. The electromagnetic plate 45 is placed under the photovoltaic panel 2 when not in use.

[0067] In one embodiment, a mounting plate 453 is fixed to one side of the electromagnetic plate 45 close to the side plate 265, and a connecting piece 47 connected to the rotating shaft 42 is provided on the mounting plate 453. A blowing mechanism 48 for blowing dust on the upper end of the photovoltaic panel 3 is provided on one side of the electromagnetic plate 45, and the blowing mechanism 48 is connected to the connecting piece 47.

[0068] This design, see Fig. 9 During the rotation of the rotating shaft 42, the connecting member 47 is driven to rotate, and then the blowing mechanism 48 is driven to blow air toward one side of the photovoltaic panel 3, so that the dust jumping up on the photovoltaic panel 3 is blown away from the photovoltaic panel 3, which can quickly improve the cleaning efficiency of the photovoltaic panel 3.

[0069] In one embodiment, the connecting member 47 includes a second gear 471 fixed on the rotating shaft 42, a connecting shaft 421 rotatably disposed on the mounting plate 453, and a third gear 472 sleeved on the connecting shaft 421, and the second gear 471 is meshedly connected with the third gear 472.

[0070] This design, see Fig.10 ,as well as Fig.11The meshing connection between the second gear 471 and the third gear 472 constitutes a stable transmission structure. When the rotating shaft 42 rotates under the drive of the motor 41, the meshing of the second gear 471 and the third gear 472 can smoothly and efficiently transmit the rotational motion to the connecting shaft 421, and then drive the blowing mechanism 48 on the connecting shaft 421 to rotate. This gear transmission method has the advantages of accurate transmission ratio, large transmission power, high transmission efficiency and long service life, which ensures the stable operation of the cleaning system. The diameter of the second gear 471 is larger than the diameter of the third gear 472. When the second gear 471 rotates one circle, the third gear 472 can rotate several circles, which can further improve the cleaning efficiency of the blowing mechanism 48 for dust on the photovoltaic panel 3.

[0071] In one embodiment, the blowing mechanism 48 includes a support block 454 fixed at intervals on the electromagnetic plate 45, a fixed shaft 483 rotatably set on the support block 454, a second bevel gear 482 fixed to the upper end of the fixed shaft 483, a first bevel gear 481 fixed on the connecting shaft 421 and a fan blade 484 fixed to the lower end of the fixed shaft 483, and the first bevel gear 481 is meshingly connected with the second bevel gear 482.

[0072] This design, see Figure 9-11 ,as well as Fig.14 The connecting shaft 421 drives the first bevel gear 481 to rotate, and the first bevel gear 481 meshes with the second bevel gear 482, driving the fixed shaft 483 to rotate, thereby causing the fan blades 484 to rotate, generating a strong airflow, which can directly blow away the dust on the upper end of the photovoltaic panel 3, improve the cleaning efficiency, ensure the cleanliness of the photovoltaic panel 3, and thus improve the photovoltaic power generation efficiency.
