Description

Technical Field

[0001] This utility model relates to the field of positioning technology, and in particular to a photovoltaic module junction box installation positioning device. Background Technology

[0002] The photovoltaic industry is progressing rapidly, and junction boxes, as one of the common auxiliary tools in the photovoltaic module production field, play a crucial role in the production, installation, and operation of photovoltaic modules.

[0003] During manual installation, existing junction boxes may shift or be improperly installed due to the lack of tools for positioning. This can lead to poor contact with the silicone sealant, causing water leakage and other quality issues. It also affects the aesthetics of the junction box within the assembly. Utility Model Content

[0004] The purpose of this utility model is to solve the following shortcomings in the prior art: during the manual installation of existing junction boxes, the lack of auxiliary positioning tools may lead to displacement or improper installation of the junction box, resulting in poor contact with the silicone sealant, causing water leakage and other quality problems. It also affects the aesthetics of the junction box on the module. Therefore, this utility model proposes a photovoltaic module junction box installation and positioning device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A photovoltaic module junction box installation and positioning device includes a mounting plate with a horizontally open sliding opening on its surface. Two I-shaped blocks are symmetrically slidably arranged within the sliding opening. An L-shaped positioning plate is fixedly installed on the lower surface of each I-shaped block. An L-shaped placement plate is fixedly installed on the surface of each I-shaped block. A circular opening is provided on the surface of the placement plate. A hollow rod with one closed end is slidably inserted into the circular opening. The open end of the hollow rod is close to the mounting plate and is fixedly mounted with a suction cup. The hollow rod is restricted from rotation by a limiting component.

[0007] The hollow rod has multiple vents in a circular shape at one closed end, and a rotating opening in the middle of the closed end. A rotating shaft is sealed and rotatably installed inside the rotating opening. Multiple sealing blocks for covering the multiple rotating openings are fixedly installed on the circumferential surface of the rotating shaft at one end inside the hollow rod. A rotating plate is fixedly installed at the other end of the rotating shaft outside the hollow rod. The rotating plate is connected to the hollow rod through an elastic component.

[0008] Preferably, the limiting component includes two limiting rods fixedly installed on the surface of the I-shaped block. The two limiting rods are located on both sides of the hollow rod, and sliders are symmetrically fixedly installed on the surface of the hollow rod. The two sliders are slidably sleeved on the two limiting rods.

[0009] Preferably, the end of the limiting rod away from the mounting plate has a thread, and a nut is threaded onto the limiting rod.

[0010] Preferably, the elastic component includes a torsion spring sleeved on the rotating shaft, with both ends of the torsion spring fixedly connected to the rotating plate and the hollow rod, respectively.

[0011] Preferably, the mounting plate has a scale on its surface, which is used to determine the length of the junction box.

[0012] Preferably, an anti-slip layer is adhered to the side of each of the two positioning plates that are close to each other, and the anti-slip layer is made of rubber.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] By using the cooperation of two I-shaped blocks and two positioning plates, the junction box can be quickly clamped and positioned during installation, ensuring its correct position. After controlling the positioned junction box to move to the appropriate installation position, the suction cups are used to position the two I-shaped blocks and two positioning plates. Finally, the junction box is installed. This avoids incorrect installation or displacement during installation, improving the aesthetics of the installed junction box and preventing problems with poor silicone contact caused by improper installation.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0021] The terms used in this utility model, such as "upper", "lower", "left", "right", "middle" and "one", are only for clarity of description and are not intended to limit the scope of implementation of this utility model. Changes or adjustments to their relative relationships, without substantially altering the technical content, should also be considered as within the scope of implementation of this utility model.

[0022] Reference Figures 1-4 A photovoltaic module junction box installation and positioning device includes a mounting plate 1. A sliding opening 2 is horizontally opened on the surface of the mounting plate 1. Two I-shaped blocks 3 are symmetrically slidably arranged in the sliding opening 2. An L-shaped positioning plate 4 is fixedly installed on the lower surface of the I-shaped blocks 3. An L-shaped placement plate is fixedly installed on the surface of the I-shaped blocks 3. A circular opening is opened on the surface of the placement plate. A hollow rod 5 with one end closed is slidably inserted into the circular opening. The open end of the hollow rod 5 is close to the mounting plate 1 and is fixedly installed with a suction cup 6. The hollow rod 5 is restricted from rotation by a limiting component. The limiting component includes two limiting rods 12 fixedly installed on the surface of the I-shaped blocks 3. The two limiting rods 12 are respectively located on both sides of the hollow rod 5. Slider 13 is symmetrically fixedly installed on the surface of the hollow rod 5. The two sliders 13 are respectively slidably sleeved on the two limiting rods 12.

[0023] The hollow rod 5 has multiple vents 7 in a circular shape at one closed end. A rotating port 8 is opened in the middle of the closed end of the hollow rod 5. A rotating shaft 9 is sealed and rotatably installed inside the rotating port 8. Multiple sealing blocks 10, which are used to cover the multiple rotating ports 8, are fixedly installed on the surface of the rotating shaft 9 in a circular shape at one end inside the hollow rod 5. A rotating plate 11 is fixedly installed at the other end of the rotating shaft 9 outside the hollow rod 5. The rotating plate 11 is connected to the hollow rod 5 through an elastic component. The elastic component includes a torsion spring 15 sleeved on the rotating shaft 9. The two ends of the torsion spring 15 are fixedly connected to the rotating plate 11 and the hollow rod 5, respectively.

[0024] When installing the junction box, first place the junction box between the two positioning plates 4, then move the two positioning plates 4 closer together until they are both against the junction box and firmly clamp it. At this point, the junction box is positioned correctly due to the pressure of the two positioning plates 4. Then, move the two positioning plates 4 laterally with the clamped junction box in place until it reaches the appropriate installation position. Finally, move the two hollow rods 5 so that the two suction cups 6 are both in contact with the junction box. When the surfaces of the mounting plate 1 come into contact, the suction cup 6 will deform under the pressure. Due to the elastic potential energy of the torsion spring 15, the multiple sealing blocks 10 on the surface of the rotating shaft 9 will cover the multiple vents 7 respectively. The multiple vents 7 will be in a closed state. Therefore, when the suction cup 6 deforms, the gas inside the suction cup 6 can only slip out from the gap between the contact surface of the suction cup 6 and the mounting plate 1. Thus, the suction cup 6 will form an adsorption with the mounting plate 1, thereby fixing the I-shaped block 3 and the positioning plate 4. Then the junction box can be installed.

[0025] After the junction box is installed, the rotating plate 11 is rotated to control the rotating shaft 9 to rotate together with the multiple sealing blocks 10, so that the multiple sealing blocks 10 no longer cover the multiple vents 7. The multiple vents 7 will be in the open state, and the outside gas will enter the hollow rod 5 and the suction cup 6 through the multiple vents 7, so that the air pressure inside and outside the suction cup 6 is the same, and the locking between the suction cup 6 and the mounting plate 1 can be easily released. When the rotating plate 11 is released, the rotating plate 11 will be rotated and reset quickly with the rotating shaft 9 and the multiple sealing blocks 10 under the elastic potential energy of the torsion spring 15. The multiple sealing blocks 10 will rotate again to cover the multiple vents 7 respectively, so that the vents 7 are closed.

[0026] The end of the limiting rod 12 away from the mounting plate 1 has a thread, and a nut 14 is threaded onto the limiting rod 12.

[0027] Nut 14 can restrict the hollow rod 5 from moving out of the round opening. When it is necessary to disassemble and replace the hollow rod 5 and the suction cup 6, the nut 14 can be rotated to separate the nut 14 from the restricting rod 12, and then the hollow rod 5 and the suction cup 6 can be removed.

[0028] The surface of the mounting plate 1 has a scale 16, which is used to determine the length of the junction box.

[0029] Both positioning plates 4 have anti-slip layers bonded to their adjacent sides. The anti-slip layers are made of rubber, which has good elasticity and adhesion, thereby increasing the friction between the positioning plates 4 and the junction box contact surface. It also prevents wear on the junction box surface caused by clamping.

[0030] In this invention, when installing the junction box, first place the junction box between two positioning plates 4, then control the two positioning plates 4 to move closer to each other until both positioning plates 4 are against the junction box and firmly clamp the junction box. At this time, the junction box is positioned correctly by the pressure of the two positioning plates 4, and there will be no misalignment. Then, control the two positioning plates 4 to move laterally with the clamped junction box until the junction box moves to the appropriate installation position. At this time, control the movement of the two hollow rods 5 to make the two suction... The suction cup 6 is pressed against the surface of the mounting plate 1. The suction cup 6 will deform under the pressure. Due to the elastic potential energy of the elastic component, the multiple sealing blocks 10 on the surface of the rotating shaft 9 will cover the multiple vents 7 respectively. The multiple vents 7 will be in a closed state. Therefore, when the suction cup 6 deforms, the gas in the suction cup 6 can only slip out from the gap between the contact surface of the suction cup 6 and the mounting plate 1. Thus, the suction cup 6 will form an adsorption with the mounting plate 1, thereby fixing the I-shaped block 3 and the positioning plate 4. Then the junction box can be installed.

[0031] In this utility model, unless otherwise explicitly specified and limited, the terms "installation", "connection", "linking", "fixing", etc., should be interpreted broadly.

[0032] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
