Description

Technical Field

[0001] This utility model relates to the field of auxiliary equipment for power distribution box installation, and in particular to a power distribution box mounting bracket. Background Technology

[0002] With the development of the photovoltaic industry, photovoltaic panels have begun to be installed in mountainous areas and beyond, starting from plains where they are easy to lay. Installing photovoltaic power generation equipment requires various electrical devices, including inverters and circuit breakers. These devices are susceptible to rain erosion in the field, so they are usually installed in distribution boxes. These distribution boxes are typically mounted on cylindrical photovoltaic panel support columns. Currently, a method for mounting distribution boxes on pole-like structures is used, such as the distribution box for temporary power supply projects disclosed in Chinese Patent Application No. 202121295277.3. This technical solution relies on the column structure of utility poles, light poles, etc., for installation, which not only simplifies the support structure but also makes the construction more stable. Specifically, this utility model welds a C-shaped steel with a mounting plate to the rear side of the box body, and clamps with folded edges at both ends are attached to the column. Bolts pass through the mounting plate and folded edges and are then tightened with nuts. Based on this structure, the C-shaped steel and clamps are stably fixed to the column, thus providing installation and fixation for the box body. The nuts on these mounting brackets are exposed. Since photovoltaic power stations are located in the field, the exposed nuts can be dismantled by humans, allowing the entire distribution box to be removed and stolen. Therefore, a distribution box mounting bracket is needed that allows the distribution box to be dismantled only after the distribution box is opened, thus improving the anti-theft performance of the distribution box. Utility Model Content

[0003] To address the aforementioned issues, this utility model proposes a distribution box mounting bracket, which allows the distribution box to be disassembled only after the distribution box is opened, thereby improving the anti-theft performance of the distribution box.

[0004] This utility model is achieved through the following technical solutions;

[0005] This utility model proposes a distribution box mounting bracket, comprising: a first connecting plate, a second connecting plate, a distribution box, a support rod, and a first bolt. The first connecting plate and the second connecting plate are respectively disposed at both ends of the support rod. The first connecting plate has a first groove on both sides, and the second connecting plate has a second groove on both sides. The two ends of the first connecting plate are respectively connected to the two ends of the second connecting plate by the first bolt. A nut is disposed in the second groove. One end of the first bolt is inserted into the first groove, and the other end of the first bolt extends into the second groove and is connected to the nut. The distribution box is connected to the first connecting plate by the second bolt.

[0006] Furthermore, the first connecting plate and the second connecting plate are provided with an arc-shaped bend in the middle, and the inner diameter of the arc-shaped bend is equal to the outer diameter of the support rod.

[0007] Furthermore, the second bolt passes through the inside of the distribution box and connects to the first connecting plate. The second bolt is fitted with a sleeve, one end of which contacts the first connecting plate and the other end of which contacts the back of the distribution box.

[0008] Furthermore, the second groove is elongated, and the nut is also elongated.

[0009] Furthermore, the first bolt is an internal hex bolt, the head of the first bolt is lower than the upper part of the first groove, and the outer side of the nut is lower than the upper part of the second groove.

[0010] Furthermore, the distribution box is fixed to the support rod by two to three first connecting plates and second connecting plates.

[0011] The beneficial effects of this utility model are as follows: The first connecting plate and the second connecting plate are connected by the first bolt. After the distribution box is connected to the first connecting plate, the distribution box can block the head of the first bolt, thus preventing the first bolt from being rotated through the head of the first bolt. In addition, the nut is square, so the nut cannot be rotated in the second groove. The distribution box can be stably fixed on the support rod. After it is fixed, the first connecting plate and the second connecting plate can only be removed after the distribution box is opened and removed, which improves the anti-theft performance of the distribution box.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Throughout the description, the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions. Obviously, the described embodiments are only a part of the embodiments of the present utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0017] It should be noted that all directional indicators (such as up, down, left, right, front, back, etc.) in this utility model embodiment are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicators will also change accordingly.

[0018] Furthermore, the use of terms such as "first" and "second" in this utility model is for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, features defined with "first" and "second" may explicitly or implicitly include at least one of the stated features. Additionally, the technical solutions of the various embodiments can be combined with each other, but only on the basis of being achievable by those skilled in the art. If the combination of technical solutions is contradictory or impossible to implement, such a combination of technical solutions should be considered non-existent and not within the scope of protection claimed by this utility model.

[0019] like Figure 1 , Figure 2 , Figure 3 As shown, one embodiment of this utility model provides a distribution box mounting bracket, including: a first connecting plate 1, a second connecting plate 2, a distribution box 3, a support rod 4, and a first bolt 5. The first connecting plate 1 and the second connecting plate 2 are respectively disposed at both ends of the support rod 4. The first connecting plate 1 has a first groove 6 on both sides, and the second connecting plate 2 has a second groove 7 on both sides. The two ends of the first connecting plate 1 are respectively connected to the two ends of the second connecting plate 2 by the first bolt 5. A nut 8 is provided in the second groove 7. One end of the first bolt 5 is stuck in the first groove 6, and the other end of the first bolt 5 extends into the second groove 7 and is connected to the nut 8. The distribution box 3 is connected to the first connecting plate 1 by the second bolt 9.

[0020] The support rod 4 is used between photovoltaic panels. When installing the distribution box 3 at the lower part of the support rod 4, firstly, place the first connecting plate 1 and the second connecting plate 2 on both sides of the support rod 4. Then, after the first bolt 5 passes through the first groove 6, it passes through the second groove 7 and is screwed into the nut 8 placed in the second groove 7. The same operation is performed to fix the other side of the first connecting plate 1 and the second connecting plate 2. The tension provided by the first bolt 5 makes the first connecting plate 1 and the second connecting plate 2 clamped on the support rod 4. After installing the two sets of connecting plates on the upper part of the support rod 4, open the distribution box 3 to be installed. After putting the washer on the second bolt 9, pass it through the distribution box 3 and the sleeve 11, and connect the distribution box 3 to the first connecting plate 1, thereby completing the installation of the distribution box 3 on the support rod 4.

[0021] After installation, the end of the first bolt 5 sinks into the first groove 6, and the first groove 6 is blocked by the distribution box 3, so the first bolt 5 cannot be turned with tools. Furthermore, the nut 8 is long and narrow, and under the tension of the first bolt 5, it will be pressed tightly into the second groove 7, so external force cannot turn it. After the distribution box 3 is closed, it can prevent other personnel from disassembling the distribution box 3 by turning the first bolt 5, thereby improving the anti-theft performance of the distribution box 3.

[0022] Preferably, the first connecting plate 1 and the second connecting plate 2 are provided with an arc-shaped bending portion 10 in the middle, and the inner diameter of the arc-shaped bending portion 10 is equal to the outer diameter of the support rod 4, so that the first connecting plate 1 and the second connecting plate 2 can fit better against the support rod 4, and the first connecting plate 1 and the second connecting plate 2 can be well fixed on the support rod 4.

[0023] Preferably, the second bolt 9 passes through the inside of the distribution box 3 and connects to the first connecting plate 1. The second bolt 9 is fitted with a sleeve 11. One end of the sleeve 11 contacts the first connecting plate 1, and the other end of the sleeve 11 contacts the back of the distribution box 3. Since the side wall of the distribution box 3 is relatively thin, the sleeve 11 can support it from the back and prevent the distribution box 3 from denting due to excessive pressure from the second bolt 9.

[0024] Specifically, such as Figure 3 As shown, the second groove 7 is elongated, and the nut 8 is also elongated. Under the tension of the first bolt 5, the nut 8 is pressed tightly into the second groove 7. The elongated second groove 7 limits the nut 8, preventing the first connecting plate 1 and the second connecting plate 2 from loosening by directly rotating the nut 8.

[0025] In a preferred embodiment, the first bolt 5 is an internal hex bolt, and the head of the first bolt 5 is lower than the upper part of the first groove 6, so that the end of the first bolt 5 is completely sunk into the first groove 6, preventing thieves from rotating the end of the first bolt 5 with tools after the distribution box 3 is installed. The outer side of the nut 8 is lower than the upper part of the second groove 7, preventing the first connecting plate 1 and the second connecting plate 2 from being loosened by directly rotating the nut 8.

[0026] In a preferred embodiment, such as Figure 2 As shown, the distribution box 3 is fixed to the support rod 4 by 2 to 3 first connecting plates 1 and second connecting plates 2. This multi-point fixing effectively secures the multiple distribution boxes 3, improving their stability after fixing.

[0027] Of course, there may be other implementations of this utility model. Based on this implementation, other implementations obtained by those skilled in the art without any creative effort are all within the scope of protection of this utility model.
