Description

Technical Field

[0001] The present application relates to the field of power distribution equipment, and in particular to a power distribution cabinet. Background Art

[0002] A distribution cabinet is an electrical device mainly used for power distribution and control in power systems. It is usually made of metal materials and has a certain level of protection, which can protect the internal electrical components from the influence of the external environment.

[0003] In the related art, the distribution cabinet includes a cabinet body and a cover body. The cabinet body is hollow to facilitate the installation of electrical components. The upper end of the cabinet body is open, and the cover body is fixedly connected to the upper end of the cabinet body to protect the electrical components in the cabinet body.

[0004] However, in actual applications, the cover cannot dissipate heat from inside the cabinet, resulting in poor heat dissipation of the distribution cabinet, and thus needs to be improved. Utility Model Content

[0005] In order to improve the heat dissipation of a power distribution cabinet, the present application provides a power distribution cabinet.

[0006] The power distribution cabinet provided in this application adopts the following technical solution:

[0007] A power distribution cabinet comprises a cabinet body and a cover body; the cabinet body is hollow and has an opening at the upper end; the cover body comprises a cover plate, which is arranged at the upper end of the cabinet body, and both sides of the lower end of the cover plate abut against the outer side walls of the cabinet body to cover the opening of the cabinet body; a plurality of first heat dissipation holes are provided on both sides of the lower end of the cover plate, and the plurality of first heat dissipation holes are arranged at intervals along the length direction of the cover plate, and each first heat dissipation hole is connected to the interior of the cabinet body.

[0008] By adopting the above technical solution, in actual application, the cover plate is installed at the upper end of the cabinet to block the opening of the cabinet, so as to protect the electrical components in the cabinet, and since each first heat dissipation hole is connected to the inside of the cabinet, heat can be discharged from each first heat dissipation hole to the outside of the cabinet, thereby effectively improving the heat dissipation of the distribution cabinet; in addition, when the distribution cabinet is used outdoors in the rain, since the two sides of the lower end of the cover plate abut against the outer wall of the cabinet, each first heat dissipation hole is at a certain distance from the upper opening of the cabinet, which can minimize rainwater from flowing into the cabinet.

[0009] Preferably, both sides of the lower end of the cover plate are bent upward to form a rain shield.

[0010] By adopting the above technical solution and providing the rain shield, the rain shield can block rainwater, thereby further preventing rainwater from flowing into the cabinet through the first heat dissipation holes.

[0011] Preferably, the upper side of each rain shield portion is bent toward a side away from the cover plate to form an abutment portion, and the abutment portion abuts against the upper end of the cabinet body.

[0012] By adopting the above technical solution and providing the abutting portion, the contact area between the cover plate and the cabinet body is increased, thereby improving the installation stability between the cover plate and the cabinet body.

[0013] Preferably, both sides of the upper end of the cover plate are lower than the middle part of the upper end of the cover plate.

[0014] By adopting the above technical solution, by setting both sides of the upper end of the cover plate to be lower than the middle part of the upper end of the cover plate, the upper end of the cover plate can guide rainwater, so that rainwater flows from both sides of the cover plate to the ground, and rainwater is avoided as much as possible from accumulating on the cover plate.

[0015] Preferably, the cover body further includes a dustproof plate, which is arranged at the upper end of the cabinet body, and a plurality of second heat dissipation holes are evenly opened on the dustproof plate, and each of the second heat dissipation holes is connected to each of the first heat dissipation holes.

[0016] By adopting the above technical solution and providing a dustproof plate, dust can be reduced from entering the cabinet through the first heat dissipation hole and the second heat dissipation hole, and rainwater can also be reduced from entering the cabinet.

[0017] Preferably, four sides of the dustproof plate are bent upward to form a reinforcement portion.

[0018] By adopting the above technical solution and providing the reinforcement portion, the overall structural strength of the dustproof plate is improved, thereby increasing the service life of the cover.

[0019] Preferably, a plurality of third heat dissipation holes are provided on both sides of the cabinet.

[0020] By adopting the above technical solution and providing a plurality of third heat dissipation holes, the heat in the cabinet can also be discharged from both sides of the cabinet, thereby further improving the heat dissipation performance of the power distribution cabinet.

[0021] Preferably, a plurality of rain shields are provided on both sides of the cabinet body, each of the rain shields is located at each of the third heat dissipation holes, and the opening of each of the rain shields is arranged downward to cover each of the third heat dissipation holes.

[0022] By adopting the above technical solution and providing a plurality of rain shields, rainwater can be prevented from entering the cabinet through the third heat dissipation holes as much as possible.

[0023] In summary, this application includes at least one of the following beneficial technical effects:

[0024] 1. In actual use, the cover plate is installed at the upper end of the cabinet to block the cabinet opening, thereby protecting the electrical components in the cabinet. Since each first heat dissipation hole is connected to the interior of the cabinet, heat can be discharged from each first heat dissipation hole to the outside of the cabinet, thereby effectively improving the heat dissipation performance of the power distribution cabinet. In addition, when the power distribution cabinet is used outdoors in the rain, since both sides of the lower end of the cover plate abut against the outer wall of the cabinet, each first heat dissipation hole is at a certain distance from the upper end opening of the cabinet, which can minimize the flow of rainwater into the cabinet.

[0025] 2. By providing a rain shield, the rain shield can block rainwater, further preventing rainwater from flowing into the cabinet through each first heat dissipation hole;

[0026] 3. By setting up the dustproof plate, dust can be reduced from entering the cabinet through the first heat dissipation hole and the second heat dissipation hole, and rainwater can also be reduced from entering the cabinet. BRIEF DESCRIPTION OF THE DRAWINGS

[0034] The present application may be embodied in a variety of different forms and is not limited to the embodiments described herein. In the present application, reference to terms such as "one embodiment," "some embodiments," "examples," "specific examples," or "some examples" means that the specific features, structures, materials, or characteristics described in conjunction with the embodiment or example are included in at least one embodiment or example of the present application.

[0035] In the description of the present application, "plurality" means two or more, unless otherwise clearly defined.

[0036] The following is combined with Figure 1-5 This application is described in further detail.

[0037] An embodiment of the present application discloses a power distribution cabinet.

[0038] Reference Figure 1 The distribution cabinet includes a cabinet body 1 and a cover body 2. The cabinet body 1 is hollow for installation of various electrical components. At the same time, the upper end of the cabinet body 1 is open, and the cover body 2 is provided at the upper end of the cabinet body 1 to cover the opening of the cabinet body 1.

[0039] Reference Figure 1 and Figure 2 Specifically, the cover 2 includes a cover plate 21, which is fixedly connected to the upper end of the cabinet 1. Both sides of the lower end of the cover plate 21 abut against the outer wall of the cabinet 1 to shield the opening of the cabinet 1 and prevent rain and dust from entering the cabinet 1. A plurality of first heat dissipation holes 211 are formed on both sides of the lower end of the cover plate 21. The plurality of first heat dissipation holes 211 are arranged in a strip shape and are evenly spaced along the length of the cover plate 21. Each first heat dissipation hole 211 communicates with the interior of the cabinet 1.

[0040] In actual application, the cover 21 is installed at the upper end of the cabinet 1 to block the opening of the cabinet 1 so as to protect the electrical components in the cabinet 1. Since each first heat dissipation hole 211 is connected to the interior of the cabinet 1, heat can be discharged from each first heat dissipation hole 211 to the outside of the cabinet 1, thereby effectively improving the heat dissipation of the distribution cabinet.

[0041] In addition, when the distribution cabinet is used outdoors in the rain, since the two sides of the lower end of the cover 21 abut against the outer wall of the cabinet body 1, each first heat dissipation hole 211 is at a certain distance from the upper end opening of the cabinet body 1, making it difficult for rainwater to reach the upper end of the cabinet body 1, thereby avoiding rainwater from flowing into the cabinet body 1 as much as possible, thereby improving the protection capability of the electrical components of the cabinet body 1.

[0042] Reference Figure 2 and Figure 3In some embodiments, both sides of the lower end of the cover plate 21 are bent upward to form a rain shield 212. The rain shield 212 is arranged in a rectangular plate shape and extends to the upper end of the cabinet 1, so that the rain shield 212 can block rainwater entering from each first heat dissipation hole 211, and can further prevent rainwater from flowing from each first heat dissipation hole 211 into the cabinet 1, thereby ensuring that the electrical components in the cabinet 1 can work normally even in heavy rain weather.

[0043] In some embodiments, the upper sides of the two rain shielding portions 212 are bent toward the side away from the cover plate 21 (i.e., the side where the two rain shielding portions 212 are close to each other) to form an abutting portion 213, and the abutting portion 213 is also arranged in a rectangular plate shape, and the lower side of the abutting portion 213 abuts against the upper end of the cabinet body 1 to increase the contact area between the cover plate 21 and the cabinet body 1, thereby improving the installation stability between the cover plate 21 and the cabinet body 1.

[0044] In some embodiments, both sides of the upper end of the cover plate 21 are lower than the middle part of the upper end of the cover plate 21, that is, the middle position of the upper end of the cover plate 21 is the highest, so that the upper end of the cover plate 21 is arranged in a "human" shape. When rainwater flows to the upper end of the cover plate 21, the upper end of the cover plate 21 guides the rainwater and under the action of gravity, the rainwater flows from both sides of the cover plate 21 to the ground, avoiding rainwater accumulation on the cover plate 21 as much as possible, and preventing rainwater from flowing into the cabinet body 1.

[0045] Reference Figure 3 and Figure 4 In some embodiments, the cover 2 further includes a dustproof plate 22, which is arranged in a rectangular plate shape. The dustproof plate 22 is fixedly connected to the upper end of the cabinet 1, and a plurality of second heat dissipation holes 221 are evenly opened on the dustproof plate 22. Each second heat dissipation hole 221 is connected to each first heat dissipation hole 211. On the premise of ensuring the heat dissipation inside the cabinet 1, it can reduce dust from entering the cabinet 1 through the first heat dissipation holes 211 and the second heat dissipation holes 221. At the same time, it can also reduce rainwater from entering the cabinet 1, thereby improving the protection effect of the electrical components in the cabinet 1.

[0046] In some embodiments, the four sides of the dustproof plate 22 are bent upward to form a reinforcement portion 222. The reinforcement portion 222 is arranged in a rectangular plate shape, which can effectively improve the overall structural strength of the dustproof plate 22, thereby increasing the service life of the cover body 2.

[0047] Reference Figure 1 and Figure 5 In some embodiments, a plurality of third heat dissipation holes 11 are provided on both sides of the cabinet 1. The third heat dissipation holes 11 are also strip-shaped holes, so that the heat in the cabinet 1 can also be discharged from both sides of the cabinet 1, further improving the heat dissipation of the distribution cabinet.

[0048] In some embodiments, a plurality of rain shields 12 are provided on both sides of the cabinet 1. The number of rain shields 12 corresponds to the number of third heat dissipation holes 11, i.e., the number of rain shields 12 is the same as the number of third heat dissipation holes 11. Each rain shield 12 is located at each third heat dissipation hole 11, and the opening of each rain shield 12 is arranged downward to block each third heat dissipation hole 11, thereby minimizing rainwater from entering the cabinet 1 through each third heat dissipation hole 11, thereby ensuring the normal operation of the electrical components in the cabinet 1 during rain. The rain shields 12 are formed by pressing the sides of the cabinet 1, which can improve the structural strength of the two sides of the cabinet 1.

[0049] The implementation principle of this embodiment is: in actual application, the cover plate 21 is installed at the upper end of the cabinet 1 to block the opening of the cabinet 1 to protect the electrical components in the cabinet 1, and since each first heat dissipation hole 211 is connected to the interior of the cabinet 1, heat can be discharged from each first heat dissipation hole 211 to the outside of the cabinet 1, thereby effectively improving the heat dissipation performance of the distribution cabinet.

[0050] In addition, when the distribution cabinet is used outdoors in the rain, since the two sides of the lower end of the cover 21 abut against the outer wall of the cabinet body 1, each first heat dissipation hole 211 is at a certain distance from the upper end opening of the cabinet body 1, making it difficult for rainwater to reach the upper end of the cabinet body 1, thereby avoiding rainwater from flowing into the cabinet body 1 as much as possible, thereby improving the protection capability of the electrical components of the cabinet body 1.

[0051] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
