Description

Technical Field

[0001] This utility model belongs to the field of power equipment technology, specifically relating to a solar-powered outdoor rainproof distribution box for users. Background Technology

[0002] In distributed photovoltaic (PV) power generation systems, the distribution box is an indispensable component. As the interface between the PV power plant and the power grid, the distribution box is responsible for power distribution between the two systems.

[0003] Most distribution boxes are installed outdoors and are greatly affected by the external environment, especially by temperature and humidity. Water that enters the distribution box cannot be drained, causing the cables inside to become moldy and the metal components to age, making the electrical components inside the distribution box prone to failure during use.

[0004] Currently, most outdoor distribution boxes use ventilation holes directly on the box for heat dissipation, which makes it easy for rainwater to enter the box through the ventilation holes, resulting in poor waterproofing. Utility Model Content

[0005] This utility model provides a solar-powered outdoor rainproof distribution box, which aims to improve the waterproof effect of outdoor distribution boxes.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a solar user outdoor rainproof distribution box is provided, comprising: a distribution box, the side of the distribution box is provided with a plurality of heat dissipation holes, a rain cover is provided on the side of the distribution box to cover the area where the heat dissipation holes are located, the lower end of the rain cover is provided with a heat dissipation opening, and a heat dissipation space is reserved between the rain cover and the side of the distribution box.

[0007] In one possible implementation, the upper end of the rain cover is provided with a guide slope.

[0008] In one possible implementation, the three inner boundaries of the rain cover correspond one-to-one with the three boundaries enclosed by the area where the heat dissipation holes are located, and the distance between the corresponding boundaries is at least 5mm, so as to form a heat dissipation channel.

[0009] In one possible implementation, the lower end of the rain cover is tilted outwards to make the heat dissipation opening flared.

[0010] In one possible implementation, the distribution box has a window on its front side, and a door on its front side to cover the window; wherein, the window has a forward-extending rain guide edge around its perimeter, and the edge of the rain guide edge has a rain-proof edge that bends outwards; the inner side of the door has a rearward-extending shielding edge corresponding to the window; when the door is closed on the window, the shielding edge wraps around the outside of the rain-proof edge and the rain guide edge.

[0011] In one possible implementation, an annular sealing strip is provided on the inner side of the door to abut against the rainproof edge.

[0012] In one possible implementation, the top plate of the distribution box has a forward-extending rainproof edge, the width of which is at least flush with the closed door.

[0013] In one possible implementation, the box door is connected to the front side of the distribution box via a hinge.

[0014] In one possible implementation, the rain cover is welded to the electrical distribution box.

[0015] Compared with the prior art, the solar user outdoor rainproof distribution box provided by this utility model has the following advantages: a rain cover is installed on the outside of the area where the heat dissipation holes are located, which effectively blocks rainwater and prevents rainwater from directly entering the distribution box through the heat dissipation holes, thus avoiding the problem of moisture damage to the electrical components inside the distribution box; the rain cover has a downward-facing heat dissipation opening and a heat dissipation space is reserved between the rain cover and the distribution box, which can not only ensure the normal heat dissipation of the distribution box, but also prevent rainwater backflow, ensuring the stable operation of the distribution box in complex outdoor environments, improving its rainproof performance, avoiding the risk of failure of electrical components inside the distribution box due to rainwater soaking, dampness, mold, etc., and also extending the service life of electrical components.

[0017] To make the technical problems, technical solutions, and beneficial effects of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0018] It should be noted that in this application, the term "front" refers to the side of the distribution box where the box door is located, that is, the side where the operator directly faces the distribution box. With the operator facing the front of the distribution box as the basic direction, the left and right hands correspond to the left and right sides, respectively.

[0019] Please see Figures 1 to 8 The present invention provides a description of the solar user outdoor rainproof distribution box. The solar user outdoor rainproof distribution box includes: a distribution box 1, a plurality of heat dissipation holes 11 provided on the side of the distribution box 1, a rain cover 2 provided on the side of the distribution box 1 to cover the area where the heat dissipation holes 11 are located, a heat dissipation opening 22 provided at the lower end of the rain cover 2, and a heat dissipation space 8 reserved between the rain cover 2 and the side of the distribution box 1.

[0020] Compared with the prior art, the solar user outdoor rainproof distribution box provided by this utility model has the following advantages: a rain cover 2 is set on the outside of the area where the heat dissipation hole 11 is located, which can effectively block rainwater and prevent rainwater from directly entering the distribution box 1 through the heat dissipation hole 11, causing the electrical components inside the distribution box 1 to be damaged by moisture; the rain cover 2 has a heat dissipation opening 22 facing downwards, and a heat dissipation space 8 is reserved between the rain cover 2 and the distribution box 1, which can not only ensure the normal heat dissipation of the distribution box 1, but also prevent rainwater backflow, ensuring the stable operation of the distribution box 1 in complex outdoor environments, improving its rainproof performance, avoiding the risk of failure of the electrical components inside the distribution box 1 due to rainwater soaking, dampness, mold, etc., and also improving the service life of the electrical components.

[0021] Compared to a distribution box 1 with directly installed heat dissipation holes 11, this application provides a rain shield 2 outside the heat dissipation holes 11. When rainwater hits the rain shield 2, it flows down along the rain shield 2 and away from the bottom edge of the distribution box 1, without entering the heat dissipation holes 11. Figure 8 As indicated by the middle arrow.

[0022] During heat dissipation, the hot air inside the distribution box 1 enters the heat dissipation space 8 reserved inside the rain cover 2 through the heat dissipation hole 11, and escapes into the outside space from the heat dissipation opening 22 at the lower end of the rain cover 2, which enables the outside air and the air inside the distribution box 1 to flow with each other, ensuring the heat dissipation effect of the distribution box 1.

[0023] The design of setting a rain cover 2 outside the heat dissipation hole 11 can also play a role in dust prevention. Due to the curved channel formed by the outside air and the space inside the distribution box 1, it is difficult for outside dust to directly enter the distribution box 1, and the dust prevention effect of the distribution box 1 can also be improved.

[0024] The heat dissipation hole 11 provided in this application can be an elongated hole, a circular hole, or a polygonal hole. When it is an elongated hole, its length can extend in the front-to-back direction or in the up-and-down direction. In this case, it is not necessary to set an outwardly protruding and downwardly turned-down baffle for a single heat dissipation hole 11. For example, the existing distribution box 1 is equipped with such a baffle for a single heat dissipation hole 11, which is also to prevent rainwater from entering the distribution box 1 through the heat dissipation hole 11. The heat dissipation hole provided in this application can be directly opened on the distribution box 1, and all the heat dissipation holes 11 on the same side can be covered by the overall rain cover 2 on the outside. In this way, the heat dissipation hole 11 can be made simply by drilling holes, which is simple and convenient to make. The three edges of the rain cover 2 can be directly welded to the distribution box 1, and the installation of the rain cover 2 is also simple and convenient.

[0025] The application is titled "Solar User Outdoor Rainproof Distribution Box". In practical applications, it is not limited to solar energy applications, but can also be used for outdoor farmland hydroelectric power generation, municipal outdoor power supply, and other applications.

[0026] The distribution box 1 provided in this application serves the following function in the solar power generation system: (1) Grid connection: Distribution box 1 is the connection interface between the photovoltaic power station and the power grid, ensuring that the power can be smoothly connected to the power grid.

[0027] (2) Protection functions: Distribution box 1 is usually equipped with lightning protection, surge protection and other functions to ensure the safe operation of the power grid and photovoltaic system.

[0028] (3) Monitoring and management: Some distribution boxes 1 are also equipped with a monitoring system, which can monitor the operating status of the equipment in real time, making it convenient for management and maintenance.

[0029] Generally speaking, the composition and design requirements of distribution box 1 are as follows: (1) Basic structure: Distribution box 1 includes the box body, internal electrical components (such as inverters, transformers, switches, etc.) and monitoring system.

[0030] (2) Electrical components: including inverters, transformers, switches, etc. These components work together to ensure the efficient conversion and safe transmission of electrical energy.

[0031] (3) Monitoring system: Real-time monitoring of equipment operating status, providing fault warnings and maintenance prompts, improving system reliability and maintenance efficiency.

[0032] In some embodiments, see Figure 1 and Figure 8 As shown, the upper end of the rain cover 2 is provided with a guide slope 21. The guide slope 21 can effectively guide rainwater to flow down the slope, thereby avoiding the accumulation of rainwater on the rain cover 2 and preventing the risk of rainwater seeping into the distribution box 1 from possible welding gaps. At the same time, the design of the guide slope 21 can also disperse the impact force of rainwater to a certain extent, reduce the scouring pressure of rainwater on the rain cover 2, help improve the overall stability and durability of the rain cover 2, extend its service life, and reduce maintenance costs.

[0033] In some embodiments, the three inner boundaries of the rain cover 2 correspond one-to-one with the three boundaries enclosed by the area where the heat dissipation holes 11 are located, and the distance L between the corresponding boundaries is at least 5 mm, so as to form a heat dissipation channel 9. See [reference needed] Figure 3 As shown.

[0034] By reserving a certain space between the rain cover 2 and the heat dissipation hole 11, the heat dissipation flow channel 9 between the inner side of the rain cover 2 and the area where the heat dissipation hole 11 is located can be ensured to be smooth and unobstructed. The larger corresponding boundary distance can effectively avoid the problem of poor air circulation caused by too small a distance, so that heat can be dissipated from the heat dissipation hole 11 more efficiently, thereby improving the heat dissipation efficiency of the equipment, ensuring that the performance of the distribution box 1 will not be affected by overheating during operation, extending the service life of the distribution box 1, maintaining the stable and reliable operation of the distribution box 1, and creating good heat dissipation conditions for the normal operation of the distribution box 1.

[0035] In some embodiments, the lower end of the rain cover 2 is tilted outward ( Figure 5 As shown in the diagram, the heat dissipation opening 22 is flared outwards. Firstly, the flared opening increases the heat dissipation area, allowing heat to dissipate more efficiently, effectively reducing heat buildup and decreasing the probability of malfunctions due to overheating. Secondly, the outward tilt of the lower end of the rain cover 2 to form the flared opening helps guide rainwater flow, preventing direct backflow into the opening and avoiding short circuits caused by rainwater, thus ensuring stable and reliable operation of the equipment under various weather conditions. Furthermore, the flared opening also facilitates smoother airflow, creating good convection and further improving heat dissipation efficiency.

[0036] In some embodiments, see Figure 2 and Figure 3 The front side of the distribution box 1 is provided with a window 12, and the front side of the distribution box 1 is also provided with a door 3 that covers the window 12; wherein, the window 12 is provided with a rain guide edge 5 extending forward around it, and the edge of the rain guide edge 5 is provided with a rain shield edge 6 that bends outward in all directions. The inner side of the door 3 is provided with a rearward extending shield edge 31 corresponding to the window 12; when the door 3 is closed on the window 12, the shield edge 31 wraps around the outside of the rain shield edge 6 and the rain guide edge 5.

[0037] The presence of the rain guide edge 5 can effectively guide rainwater to flow in the left and right directions before flowing downwards, preventing rainwater from hitting the window 12 directly and reducing the possibility of rainwater entering the electrical distribution box 1; the rain shield edge 6 bends in all directions to further prevent rainwater from splashing into the window 12 area from the edge of the rain guide edge 5, enhancing the protection of the window 12.

[0038] See Figure 8The rain-proof edge 6 and the side of the distribution box 1 form a rain guide groove 7. The rain guide edge 5 is the bottom of the rain guide groove 7. Rainwater falling on the rain guide edge 5 will flow to the left and right along the rain guide edge 5 and downward along the left and right sides of the rain guide edge 5 due to the protection of the rain-proof edge 6. It will not enter the window 12, and therefore will not enter the distribution box 1. It also avoids the possibility of rainwater entering the wiring box from the window 12 on the distribution box 1, and further improves the rainproof effect of the distribution box 1.

[0039] In some embodiments, see Figure 2 As shown, an annular sealing strip 32 is provided on the inner side of the box door 3 to abut against the rainproof edge 6, which improves the sealing performance between the box door 3 and the distribution box 1 and prevents some rainwater from seeping into the distribution box 1 from the gap between the box door 3 and the side of the distribution box 1 along the inner side of the box door 3.

[0040] In some embodiments, see Figure 2 and Figure 3 The top plate 4 of the distribution box 1 has a forward-extending rain-shielding edge 41, the width of which is at least flush with the closed door 3. This forward extension of the rain-shielding edge 41 effectively prevents rainwater from directly hitting the door 3. In harsh rainy conditions, rainwater will not flow into the distribution box 1 along the edge of the door 3, thus greatly reducing the probability of short circuits or damage to electrical components caused by rainwater intrusion. This ensures the stable operation of the electrical equipment inside the distribution box 1 and extends its service life.

[0041] In some embodiments, see Figure 2 As shown, the door 3 is connected to the front of the distribution box 1 via a hinge. The door 3 basically occupies the entire front of the distribution box 1, facilitating the installation, maintenance, and replacement of electrical components.

[0042] In some embodiments, see Figure 1 As shown, the rain cover 2 is welded to the distribution box 1. The rain guide edge 5 at the window 12 of the distribution box 1 is also welded to the distribution box 1.

[0043] In the above embodiments, the descriptions of each embodiment have different focuses. For parts that are not described in detail or recorded in a certain embodiment, please refer to the relevant descriptions of other embodiments.

[0044] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
