Description

Technical Field

[0001] This utility model relates to the field of combiner box brackets, and in particular to a combiner box bracket that is easy to install. Background Technology

[0002] A combiner box is a wiring device in a photovoltaic power generation system that ensures the orderly connection and current collection function of photovoltaic modules. It is responsible for integrating the output current of multiple photovoltaic modules into one or more channels for subsequent processing and transmission. The combiner box also has circuit protection functions. The built-in fuses or circuit breakers can quickly cut off the circuit when abnormalities such as overcurrent or short circuit occur in the system, ensuring system safety.

[0003] In related technologies, the combiner box is usually installed next to the photovoltaic panel. To keep it away from the ground, the combiner box is usually mounted on a bracket. To facilitate the installation of the combiner box, workers usually have to weld a special bracket according to the size of the combiner box. This type of bracket has high structural strength. However, because the connection structure is welded, the structure of the combiner box's corner connecting frame is fixed. During subsequent maintenance and disassembly, workers need to cut right angles. This installation structure is inconvenient for workers to maintain and disassemble.

[0004] Therefore, it is necessary to provide a conveniently installed combiner box bracket to solve the above-mentioned technical problems. Utility Model Content

[0005] To address the issue that the aforementioned junction box brackets are all fixed points, requiring workers to cut right angles during subsequent maintenance and disassembly, which is inconvenient for workers' subsequent maintenance and disassembly, this utility model provides a junction box bracket that is easy to install.

[0006] This utility model provides a conveniently installed combiner box bracket, comprising: a first bracket, a second bracket disposed above the first bracket, support frames attached to both sides of the first bracket and the second bracket, and protrusions fixedly connected inside the two support frames, with multiple protrusions evenly spaced.

[0007] Multiple limiting frames are respectively fixedly mounted on the first bracket and the second bracket. A third fixing bolt is movably connected inside each of the multiple limiting frames. One end of each of the multiple third fixing bolts is engaged with an arc-shaped plate. One side of each of the multiple arc-shaped plates is fixedly connected to a junction box bracket body.

[0008] Multiple support blocks are fixedly disposed below the first bracket and the second bracket respectively. Each of the multiple support blocks is internally engaged with a second fixing bolt. One end of each of the multiple second fixing bolts is movably connected to a limit block, which is movably engaged between the multiple protrusions.

[0009] Preferably, each of the plurality of support blocks is internally engaged with a first fixing bolt, and the lower parts of the first bracket and the second bracket are respectively engaged with the plurality of the first fixing bolts.

[0010] Preferably, each of the two support frames has a slider slidably disposed inside, and each of the two sliders has a support plate fixedly connected inside, with the surface of the second fixing bolt engaging with the support plate.

[0011] Preferably, a bearing ring is fixedly connected inside the limiting block, and the bearing ring is sleeved on one end surface of the second fixing bolt.

[0012] Preferably, a waist hole is provided on one side of the limiting frame, the third fixing bolt slides inside the waist hole, and square grooves are provided on both the upper and lower sides of the limiting frame, with the two square grooves located on the upper and lower sides of the third fixing bolt respectively.

[0013] Preferably, a limiting nut is fixedly connected to one side of each of the plurality of arc-shaped plates, and the plurality of limiting nuts are respectively threaded onto one end surface of the plurality of third fixing bolts.

[0014] Compared with related technologies, the convenient-to-install combiner box bracket provided by this utility model has the following advantages:

[0015] 1. The worker first places two support frames on the ground. Support blocks are installed inside the two support frames, with the sides of the support blocks fitting against the surface of the support frames. The upper side of the other side of the support blocks fits against the first and second brackets respectively. The support blocks slide on one side of the support frames. After the height of the support blocks is adjusted, the second fixing bolt is rotated. One end of the second fixing bolt fits against the inner wall of the support frame through a limiting block. The upper and lower parts of the limiting block fit against multiple protrusions respectively. By adjusting the height of the support blocks, the distance and height between the first and second brackets can be easily adjusted, facilitating the fixing of the combiner box bracket body. After the first and second brackets are fixed, the worker inserts the third fixing bolt into the inside of the limiting frame. The third fixing bolt will slide inside the limiting frame. By adjusting the distance between the two third fixing bolts, it is easy for the third fixing bolt to be inserted into the inside of the arc plate. The arc plate is welded to the outer wall of the combiner box bracket body, increasing the stability of the combiner box bracket body installation and facilitating the subsequent installation and disassembly of the combiner box bracket body.

[0016] 2. The support plate supports the second fixing bolt. The engagement between the surface of the second fixing bolt and the support plate will push the limiting block at one end. Multiple bosses are equidistantly pressed against the inner wall of one side of the support frame. The spacing between the multiple bosses facilitates the insertion of the limiting block. The limiting block is limited by the multiple bosses, increasing the stability of the support block. The bearing ring reduces the friction between one end of the second fixing bolt and the surface of the limiting block. When the second fixing bolt rotates, the limiting block will not rotate with the second fixing bolt during sliding, making it convenient to insert the limiting block between the multiple bosses and increasing stability.

[0022] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0023] Please refer to the following: Figures 1 to 4A conveniently installed combiner box bracket includes: a first bracket 1, multiple limiting brackets 4 and multiple support blocks 5. A second bracket 2 is provided above the first bracket 1. Support brackets 3 are attached to both sides of the first bracket 1 and the second bracket 2. Bosses 31 are fixedly connected inside the two support brackets 3. Multiple bosses 31 are equidistantly arranged. Multiple limiting brackets 4 are respectively fixedly installed on the first bracket 1 and the second bracket 2. Third fixing bolts 6 are movably connected inside the multiple limiting brackets 4. Arc plates 7 are engaged at one end of the multiple third fixing bolts 6. Combiner box bracket body 9 is fixedly connected to one side of the multiple arc plates 7. Multiple support blocks 5 are respectively fixedly installed below the first bracket 1 and the second bracket 2. Second fixing bolts 52 are engaged inside the multiple support blocks 5. Limiting blocks 53 are movably connected at one end of the multiple second fixing bolts 52. The limiting blocks 53 are movably engaged between the multiple bosses 31.

[0024] In this way, during the implementation process, when the worker needs to install the junction box bracket body 9, the worker first places two support frames 3 on the ground. The support blocks 5 are installed inside the two support frames 3. The side of the support block 5 is in contact with the surface of the support frame 3, and the other side of the support block 5 is in contact with the first bracket 1 and the second bracket 2 respectively. The support block 5 slides on one side of the support frame 3. After the height of the support block 5 is adjusted, the second fixing bolt 52 is rotated. One end of the second fixing bolt 52 is in contact with the inner wall of the support frame 3 through the limiting block 53. The upper and lower parts of the limiting block 53 are in contact with multiple protrusions 31 respectively. By adjusting the height of the support block 5, it is convenient to adjust the distance and height between the first bracket 1 and the second bracket 2, and to fix the junction box bracket body 9.

[0025] After the first bracket 1 and the second bracket 2 are fixed, the worker inserts the third fixing bolt 6 into the inside of the limiting frame 4. The third fixing bolt 6 will slide inside the limiting frame 4. By adjusting the distance between the two third fixing bolts 6, it is convenient for the third fixing bolt 6 to be inserted into the inside of the arc plate 7. The arc plate 7 is welded to the outer wall of the junction box bracket body 9, which increases the stability of the junction box bracket body 9 installation.

[0026] The internal parts of multiple support blocks 5 are all engaged with first fixing bolts 51. The lower parts of the first bracket 1 and the second bracket 2 are respectively engaged with multiple first fixing bolts 51. The lower parts of the first bracket 1 and the second bracket 2 are respectively attached to two support blocks 5. The first fixing bolts 51 penetrate the support blocks 5 and are rotatably inserted into the interior of the first bracket 1 and the second bracket 2. The engagement of the first fixing bolts 51 with the first bracket 1 and the second bracket 2 increases the stability of the connection between the support block 5 and the first bracket 1 and the second bracket 2.

[0027] Preferably, each of the two support frames 3 has a slider 54 slidably installed inside, and each of the two sliders 54 has a support plate 55 fixedly connected inside. The surface of the second fixing bolt 52 is engaged with the support plate 55. The slider 54 limits the support plate 55, and the support plate 55 supports the second fixing bolt 52. The engagement between the surface of the second fixing bolt 52 and the support plate 55 will push the limiting block 53 at one end. Multiple protrusions 31 are equidistantly attached to the inner wall of one side of the support frame 3. The spacing between the multiple protrusions 31 facilitates the insertion of the limiting block 53. The limiting block 53 is limited by the multiple protrusions 31, increasing the stability of the support block 5.

[0028] Specifically, a bearing ring 56 is fixedly connected inside the limiting block 53. The bearing ring 56 is sleeved on one end surface of the second fixing bolt 52. The bearing ring 56 reduces the friction between one end of the second fixing bolt 52 and the surface of the limiting block 53. When the second fixing bolt 52 rotates, the limiting block 53 will not rotate with the second fixing bolt 52 during sliding, making it convenient to insert the limiting block 53 between multiple bosses 31 and increasing stability.

[0029] More specifically, a waist hole 41 is provided on one side of the limiting frame 4, and the third fixing bolt 6 slides inside the waist hole 41. Square grooves 42 are provided on both the upper and lower sides of the limiting frame 4, and the two square grooves 42 are respectively located on the upper and lower sides of the third fixing bolt 6. The waist hole 41 is horizontally opened to facilitate the horizontal movement of the third fixing bolt 6. The horizontal movement of the third fixing bolt 6 can adjust the distance between the two third fixing bolts 6. When the two third fixing bolts 6 are respectively inserted into the interior of the two arc plates 7, the worker can insert tools into the interior of the limiting frame 4 through the square grooves 42, which makes it convenient for the worker to rotate the third fixing bolt 6.

[0030] Furthermore, during implementation, a limit nut 8 is fixedly connected to one side of each of the multiple arc plates 7. The multiple limit nuts 8 are threaded onto one end surface of each of the multiple third fixing bolts 6. The limit nuts 8 are welded inside the arc plates 7. After rotating the inside of the third fixing bolts 6, the third fixing bolts 6 will engage with the limit nuts 8. The limit nuts 8 increase the stability of the connection between the third fixing bolts 6 and the arc plates 7.

[0031] The working principle of the conveniently installed combiner box bracket provided by this utility model is as follows:

[0032] When installing the junction box bracket body 9, the worker first places two support frames 3 on the ground. Support blocks 5 are installed inside the two support frames 3, with the sides of the support blocks 5 fitting against the surface of the support frame 3. The upper side of the other side of the support blocks 5 fits against the first bracket 1 and the second bracket 2, respectively. The support blocks 5 slide on one side of the support frame 3. After the height of the support blocks 5 is adjusted, the second fixing bolt 52 is rotated. One end of the second fixing bolt 52 fits against the inner wall of the support frame 3 through a limiting block 53. The upper and lower parts of the limiting block 53 are respectively connected to multiple protrusions 3. 1. The support block 5 is adjusted to adjust the distance and height between the first bracket 1 and the second bracket 2, which facilitates the fixing of the junction box bracket body 9. After the first bracket 1 and the second bracket 2 are fixed, the worker inserts the third fixing bolt 6 into the inside of the limiting frame 4. The third fixing bolt 6 will slide inside the limiting frame 4. By adjusting the distance between the two third fixing bolts 6, it is convenient for the third fixing bolt 6 to be inserted into the inside of the arc plate 7. The arc plate 7 is welded to the outer wall of the junction box bracket body 9, which increases the stability of the junction box bracket body 9 installation.
