Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0020] Reference Figure 1 This application provides a photovoltaic distribution box, including a first box 1, a second box 3, and a bracket 6. The first box 1 has a first receiving cavity. The second box 3 is disposed within the first receiving cavity, and the second box 3 also has a second receiving cavity 5. The bracket 6 is movably inserted into the second receiving cavity 5, and the bracket 6 has a mounting groove.

[0021] Specifically, a door 2 is hinged to one side of the first housing 1, and a first receiving cavity is provided inside the first housing 1. A second housing 3 is disposed within the first receiving cavity, located in the middle of the first receiving cavity near the door 2, and has an opening on the side near the door 2. A second receiving cavity 5 is provided inside the second housing 3. A bracket 6 is movably inserted into the second receiving cavity 5, and has a mounting slot within it. By movably inserting the bracket 6 into the second receiving cavity 5, it is possible to pull the bracket 6 out of the second receiving cavity 5 of the second housing 3 through the opening of the second housing 3 and remove it outside the first housing 1. Then, the component can be installed in the mounting slot of the bracket 6 outside the first housing 1. After the component installation is completed, the bracket 6 carries the component back into the second receiving cavity 5 of the second housing 3. This overcomes the original limitation of limited space during component installation, facilitating quick component installation and wiring operations, and improving overall work efficiency.

[0022] In some specific embodiments of this application, reference is made to Figure 2 The second housing 3 is provided with at least two second receiving cavities 5. Each second receiving cavity 5 is movably inserted with a bracket 6. The second housing 3 is also provided with at least one communicating groove 13. The at least one communicating groove 13 is located between the at least two second receiving cavities 5, and the at least one communicating groove 13 is connected to the at least two second receiving cavities 5 respectively.

[0023] Specifically, the second housing 3 is provided with at least two second receiving cavities 5, and each second receiving cavity 5 is movably inserted with a bracket 6. Furthermore, the second housing 3 is also provided with at least one connecting groove 13, located between at least two second receiving cavities 5, and communicating with each of the at least two second receiving cavities 5. Simultaneously, the side of the at least one connecting groove 13 near the door 2 has an opening. By movably inserting the brackets 6 into the second receiving cavities 5, at least two brackets 6 can be pulled out from the at least two second receiving cavities 5 of the second housing 3 and taken outside the first housing 1. Outside the first housing 1, components are installed in the mounting slots of the at least two brackets 6, and wiring is performed between the components in the two mounting slots. After the component installation is completed, the two brackets 6 carry the components back to their respective second receiving cavities 5. The wiring between the components in the two mounting slots can pass through the opening of the connecting groove 13, thereby realizing the wiring and installation of the components. It can overcome the limitations of limited space when installing components, making it easier to quickly complete component installation and wiring operations, and improving overall work efficiency.

[0024] Furthermore, a baffle 14 is detachably covered on the opening of the connecting groove 13. The baffle 14 protects the wiring between the components in the two mounting slots after it passes through the opening of the connecting groove 13.

[0025] Furthermore, the internal shape and dimensions of the second receiving cavity 5 are adapted to the external shape and dimensions of the bracket 6, and the bracket 6 can be moved back and forth along the inside of the second receiving cavity 5 to ensure smooth installation or removal of the bracket 6.

[0026] Furthermore, the shape and dimensions of the stop bar 14 are consistent with the shape and dimensions of the opening of the connecting groove 13. The external length dimension of the guide rail 11 is consistent with the internal length dimension of the bracket 6, and the guide rail 11 can be moved back and forth along the inside of the mounting groove of the bracket 6 to ensure smooth installation or removal of the guide rail 11.

[0027] In some specific embodiments of this application, reference is made to Figure 2 and Figure 3 Multiple sets of positioning holes 10 are evenly arranged in the mounting groove. One set of positioning holes 10 is connected to a guide rail 11 by bolts 12. The guide rail 11 is provided with mounting positions.

[0028] Specifically, positioning strips 9 are symmetrically arranged on both sides of the bottom of the mounting groove of the bracket 6. Each positioning strip 9 has multiple positioning holes 10 evenly arranged vertically, and every two symmetrical positioning holes 10 form a group of positioning holes 10. The two ends of the guide rail 11 are connected to two of the group of positioning holes 10 by bolts 12. Furthermore, the guide rail 11 has multiple mounting positions arranged horizontally, allowing components to be installed at these positions. After the bracket 6 is pulled out of the corresponding second receiving cavity 5 and removed from the first housing 1, the guide rail 11 is removed from the positioning holes 10, allowing components to be directly installed at the mounting positions on the guide rail 11. After the components are fixed, based on the length of the wiring between the components, a suitable group of positioning holes 10 is selected, and the guide rail 11 is connected to the suitable group of positioning holes 10 by bolts 12, thus realizing the installation of the components in the mounting groove. The design of the guide rail 11 and the positioning holes 10 facilitates the quick completion of component installation and wiring operations, improving overall work efficiency.

[0029] Furthermore, the external threads of the bolt 12 used to fix the guide rail 11 are consistent with the internal threads of the positioning hole 10.

[0030] In some specific embodiments of this application, reference is made to Figure 2 and Figure 3 A handle 7 is fixedly installed on the outer side of the bracket 6. The handle 7 is connected to the side of the second receiving cavity 5 by bolts 12.

[0031] Specifically, a handle 7 is fixedly installed on the outer wall of the bracket 6 near the door 2, and the handle 7 has a hole 8. An internally threaded hole 4 is provided on the end face of the edge of the second housing 3 near the door 2, and the position of the internally threaded hole 4 corresponds to that of the hole 8. After the bracket 6 is placed into the second receiving cavity 5, the hole 8 can coincide with the internally threaded hole 4, thereby connecting the handle 7 to the side of the second receiving cavity 5 via bolts 12, thus fixing the bracket 6 within the second receiving cavity 5.

[0032] Furthermore, the hole 8 has the same shape and size as the internal thread hole 4.

[0033] In some specific embodiments of this application, reference is made to Figure 4 The top of the first housing 1 is inclined, and multiple sets of water guide strips 16 are provided on the top of the first housing 1.

[0034] Specifically, a top cover 15 is fixedly installed on the top of the first housing 1. Multiple sets of water guide strips 16 are symmetrically arranged on the top surface of the top cover 15. When encountering rainy weather, rainwater falls on the top cover 15 and can flow outward through the water guide strips 16, thereby preventing rainwater from accumulating on the top cover 15 and ensuring the dryness of the first receiving cavity, the second receiving cavity 5 and the mounting groove.

[0035] In some specific embodiments of this application, reference is made to Figure 1 A dehumidifier 17 is provided on the top of the second housing 3, and the dehumidifier 17 is connected to the second receiving cavity 5. Dry gas is supplied to the second receiving cavity 5 through the dehumidifier 17.

[0036] Specifically, a dehumidification box 17 is provided on the top of the second housing 3. The output end of the dehumidification box 17 is connected to the second receiving cavity 5. Dry gas can be delivered into the second receiving cavity 5 through the dehumidification box 17, thereby further ensuring the dryness of the second receiving cavity 5 and the mounting slot, preventing the components from being damaged due to excessive moisture, and realizing the rainproof drying function.

[0037] In some specific embodiments of this application, reference is made to Figure 1 The dehumidification chamber 17 is equipped with an air inlet pipe 19, an air pump 20, and an air outlet pipe 21 connected in sequence. A desiccant 18 is placed at the end of the air inlet pipe 19 away from the air pump 20. The end of the air outlet pipe 21 away from the air pump 20 extends into the second receiving cavity 5.

[0038] Specifically, the dehumidifier 17 is sequentially connected to an air inlet pipe 19, an air pump 20, and an air outlet pipe 21. A desiccant 18 is placed at the end of the air inlet pipe 19 furthest from the air pump 20. The end of the air outlet pipe 21 furthest from the air pump 20 extends into the second receiving cavity 5, forming the output end of the dehumidifier 17. When encountering a humid environment, the air pump 20 can be turned on, and the air inlet pipe 19 draws air in through the desiccant 18. The dried air is then delivered through the air outlet pipe 21 to the second receiving cavity 5 of the second housing 3, further ensuring the dryness of the second receiving cavity 5 and the mounting slot. This prevents components from being damaged by excessive moisture and achieves a rainproof drying function. The desiccant 18 can be replaced as needed based on actual usage.

[0039] Furthermore, a vent 22 is provided on the side of the dehumidifier 17 where the desiccant 18 is placed, allowing air to be drawn into the dehumidifier 17 and come into contact with the desiccant 18 through the vent 22.

[0040] Furthermore, the exhaust pipe 21 passes through the outer wall of the second housing 3 to the second receiving cavity 5 and extends into the mounting groove, while the intake pipe 19 passes through the desiccant 18, thereby ensuring the drying effect on the mounting groove.

[0041] In some specific embodiments of this application, reference is made to Figure 1 The outer side of the second housing 3 is equipped with a heat dissipation component and a temperature detector 27. The temperature detector 27 detects the ambient temperature and sends a switching command to the heat dissipation component.

[0042] Specifically, the outer walls on both sides of the second enclosure 3 have heat dissipation components and temperature detectors 27. The temperature detectors 27 can detect the ambient temperature of the environment in which the second enclosure 3 is located and send switching commands to the heat dissipation components via a controller based on the ambient temperature. When the ambient temperature reaches a set upper limit, the heat dissipation components are activated to dissipate heat from the operating components, ensuring their safe operation.

[0043] In some specific embodiments of this application, reference is made to Figure 1 The heat dissipation assembly includes a heat spreader base 23, fins 24, and a fan 26. The heat spreader base 23 is located on the outside of the second housing 3. Multiple sets of fins 24 are provided, and these multiple sets of fins 24 are located on the side of the heat spreader base 23 away from the second housing 3. The fan 26 is located on the side of the fins 24 away from the heat spreader base 23.

[0044] Specifically, heat spreader bases 23 are symmetrically arranged on the outer walls of both sides of the second housing 3. Multiple sets of fins 24 are fixedly connected to the side of each heat spreader base 23 away from the second housing 3, and multiple sets of heat pipes 25 are fixedly connected inside each set of fins 24. A fan 26 is fixedly connected to the side of each set of fins 24 away from the heat spreader base 23. When the heat dissipation assembly is turned on, the heat emitted by the components during operation can be transferred outwards to the heat spreader base 23. The heat spreader base 23 then transfers the heat to the heat pipes 25. The liquid inside the heat pipes 25 evaporates upwards due to the heat. After rising to the top of the heat pipes 25, the evaporated liquid waits for its temperature to drop before condensing and falling back down. Simultaneously, the heat pipes 25 transfer heat to the fins 24, and the fan 26 blows the heat dissipated to the fins 24 outwards, thus achieving heat dissipation for the components.

[0045] In some specific embodiments of this application, reference is made to Figure 1 and Figure 5 The first housing 1 has multiple sets of ventilation strips 28 on one side, and the multiple sets of ventilation strips 28 are connected to the first receiving cavity.

[0046] Specifically, a plurality of ventilation strips 28 are provided on one side of the first housing 1. The plurality of ventilation strips 28 are connected to the first receiving cavity, and the plurality of ventilation strips 28 are arranged facing at least one of the fans 26, so that the fans 26 can blow the heat dissipated to the fins 24 through the ventilation strips 28 to the outside of the first housing 1, thereby realizing heat dissipation of the components.

[0047] Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this application.
