Desert areas have abundant sunshine resources, which are suitable for building large-scale photovoltaic power plants. However, the harsh environment of deserts, such as strong winds and sandstorms and low visibility, places higher demands on the efficiency and precision of on-site installation of photovoltaic panels.

[0003] One of the core processes in photovoltaic panel installation is aligning the holes in the modules and fixing them with bolts. Precise alignment of the holes is crucial for the stable installation of photovoltaic panels and ensuring their safety in subsequent use. Currently, the installation of photovoltaic panels in deserts mostly relies on manual alignment, and there are no positioning tools specifically adapted to the desert environment, making construction greatly affected by the environment.

The rotation of the vertical threaded columns causes the cross-shaped sliding plate to move downwards, causing the cylindrical electromagnet to extend half its length from the fixed cylinder and insert the extended cylindrical electromagnet into a semi-circular positioning groove on one of the photovoltaic panels. Then, the rotating knob is continued to drive the cylindrical electromagnet to be fully inserted into the semi-circular positioning groove. When the cross-shaped sliding plate moves downwards to its maximum extent, the two conical conductive rods can pierce into the sealing cavity and insert into... Inside the conductive liquid, the cylindrical electromagnet is connected to the charging power supply, enabling it to generate magnetic force and effectively attract and fix itself inside the semi-circular positioning groove. Then, another photovoltaic panel is pushed closer, allowing its semi-circular positioning groove to align with the cylindrical electromagnet, achieving rapid and effective pre-positioning of the two adjacent panels. Finally, the two adjacent photovoltaic panels are assembled using bolts, ensuring the accuracy of the corresponding mounting holes after pre-positioning and improving assembly efficiency. After assembly, rotating the knob in the opposite direction causes the cylindrical electromagnet to retract into the fixing cylinder, while the conical conductive rod disengages from the sealed cavity. After de-energizing the cylindrical electromagnet, the positioning mechanism can be pulled out.

[0028] 2. The photovoltaic panel sand-proof positioning fixture described in this application, by setting up a cleaning mechanism, when the cylindrical electromagnet is extended outward by operating the rotating knob, the downward movement of the cross-shaped sliding plate can compress the two cylindrical telescopic inflatable airbags, allowing the air inside the cylindrical telescopic inflatable airbags to enter the annular pipe through the inflation tube and be sprayed out through several air nozzles, thereby automatically cleaning the dust on the surface of the cylindrical electromagnet, ensuring the cleanliness of the surface of the cylindrical electromagnet entering the semi-circular positioning groove, and ensuring the assembly accuracy.

[0050] Specifically, during the rotation of the rotating rod 107 and the driving gear 108, the two driven gears 109 can be driven to rotate automatically, thereby driving the two vertical threaded columns 106 to rotate automatically and synchronously.

[0056] Example 2

[0057] Based on Example 1, referring to Figure 6 and Figure 7 And unlike Example 1, the following is true:

The cleaning mechanism 300 is used to clean the dust on the outer surface of the cylindrical electromagnet 102. The cleaning mechanism 300 includes two cylindrical telescopic inflatable airbags 301 fixedly mounted on the inner wall of two longitudinal rectangular slides, and the top of the two cylindrical telescopic inflatable airbags 301 are fixedly connected to the lower surface of the cross-shaped slide plate 105.

[0059] Specifically, as the cross-shaped slide plate 105 slides downward, it can automatically compress the two cylindrical telescopic inflatable airbags 301.

[0060] Please refer to this carefully. Figure 6 , Figure 7 The cleaning mechanism 300 also includes an annular mounting groove formed on the inner wall of the bottom end of the fixed cylinder 101, and an annular pipe 302 fixed on the inner wall of the annular mounting groove. The outer surface of the annular pipe 302 is provided with a number of inclined upward air nozzles 303 in a circumferential array. The inner top wall of the annular mounting groove is provided with a square groove corresponding to the air nozzles 303.

[0061] Specifically, the device can automatically clean the dust on the surface of the cylindrical electromagnet 102 during the descent process through several air nozzles 303 on the annular pipe 302.

[0062] Please refer to this carefully. Figure 6 , Figure 7 A return spring 304 is fixedly installed on the inner top wall and inner bottom wall of the cylindrical telescopic inflatable airbag 301. An inflation tube 305 is provided at the bottom end of the cylindrical telescopic inflatable airbag 301. One end of the inflation tube 305 extends into the interior of the cylindrical telescopic inflatable airbag 301, and the other end of the inflation tube 305 extends into the interior of the annular pipe 302. An air intake tube 306 is also provided on the outer annular surface of the bottom end of the cylindrical telescopic inflatable airbag 301. One end of the air intake tube 306 extends into the interior of the cylindrical telescopic inflatable airbag 301, and the other end of the air intake tube 306 is provided with a filter cover. An inflation one-way valve and an air intake one-way valve are respectively provided on the surface of the inflation tube 305 and the air intake tube 306.

[0063] Specifically, when the cylindrical telescopic inflatable airbag 301 is squeezed, air can be inflated into the annular pipe 302 through the inflation tube 305. After the cross-shaped slide plate 105 moves upward, the cylindrical telescopic inflatable airbag 301 can automatically reset under the action of the return spring 304, and external air can be drawn into the cylindrical telescopic inflatable airbag 301 through the suction tube 306, so that it can be used again.

[0064] In this embodiment, by setting up a cleaning mechanism 300, during the process of extending the cylindrical electromagnet 102 outward by operating the rotating knob 104, the downward movement of the cross-shaped sliding plate 105 can compress the two cylindrical telescopic inflatable airbags 301, allowing the air inside the cylindrical telescopic inflatable airbags 301 to enter the annular pipe 302 through the inflation tube 305 and be sprayed out through several air nozzles 303, thereby automatically cleaning the dust on the surface of the cylindrical electromagnet 102, ensuring the cleanliness of the surface of the cylindrical electromagnet 102 entering the semi-circular positioning groove 103, and ensuring the assembly accuracy.

[0065] Working principle: By setting up a positioning mechanism 100, when assembling two adjacent photovoltaic panels 200, the rotary knob 104 is operated first to drive the active gear disk 108 to rotate. The rotation of the active gear disk 108 drives the two driven gear disks 109 to rotate, thereby driving the two vertical threaded columns 106 to rotate simultaneously. The rotation of the vertical threaded columns 106 drives the cross-shaped sliding plate 105 to move downwards, causing the cylindrical electromagnet 102 to extend half its length from the fixed cylinder 101. The extended cylindrical electromagnet 102 is then inserted into a semi-circular positioning groove 1 on a photovoltaic panel 200. 03. Then, continue rotating the knob 104 to fully insert the cylindrical electromagnet 102 into the semi-circular positioning groove 103. When the cross-shaped sliding plate 105 moves downward to its maximum limit, the two conical conductive rods 1014 can pierce into the sealed cavity 1012 and insert into the conductive liquid, so that the cylindrical electromagnet 102 is connected to the charging power supply 1010. This allows the cylindrical electromagnet 102 to generate magnetic force and effectively attract and fix itself inside the semi-circular positioning groove 103. Then, push the other photovoltaic panel 200 closer to it, so that the other photovoltaic panel... The semi-circular positioning groove 103 on the plate 200 can fit the cylindrical electromagnet 102, achieving the purpose of quickly and effectively pre-positioning two adjacent photovoltaic panels 200. Finally, the two adjacent photovoltaic panels 200 are assembled with bolts, ensuring the accuracy of the corresponding mounting holes after the pre-positioning of the two adjacent photovoltaic panels 200, improving assembly efficiency. After assembly, rotating the rotary knob 104 in the opposite direction drives the cylindrical electromagnet 102 into the fixed cylinder 101, while the conical conductive rod 1014 disengages from the sealed cavity 1012. After the power to the cylindrical electromagnet 102 is turned off, the positioning groove is pulled out. Mechanism 100 is sufficient. Moreover, during the process of extending the cylindrical electromagnet 102 outward by operating the rotating knob 104, the downward movement of the cross-shaped sliding plate 105 can compress the two cylindrical telescopic inflatable airbags 301, allowing the air inside the cylindrical telescopic inflatable airbags 301 to enter the annular pipe 302 through the inflation tube 305 and be ejected through several air nozzles 303, thereby automatically cleaning the dust on the surface of the cylindrical electromagnet 102, ensuring the cleanliness of the surface of the cylindrical electromagnet 102 entering the semi-circular positioning groove 103, and ensuring the accuracy of assembly.
