Description

Technical Field

[0001] This utility model relates to the field of power distribution cabinet drainage technology, and in particular to a drainage structure for power distribution cabinets. Background Technology

[0002] Distribution cabinets are crucial equipment in power systems, used to distribute and control electrical energy to ensure safe and stable power transmission. Since distribution cabinets are typically located outdoors, the impact of rain and humid air on their internal components is significant. For a long time, the waterproof design and heat dissipation capabilities of distribution cabinets have directly affected their performance and lifespan. However, existing distribution cabinet waterproof structures often lack effective drainage and heat dissipation measures, leading to rainwater accumulation and causing corrosion and short circuits in internal components. This not only affects the normal operation of the equipment but can also cause serious economic losses and safety hazards.

[0003] Traditional distribution cabinet designs often employ waterproof materials and sealed structures to prevent moisture intrusion, but these measures frequently negatively impact heat dissipation. Internal components generate significant heat during operation; if this heat cannot be dissipated effectively, it can lead to overheating and affect the stability of the power system. Furthermore, some designs lack sufficient drainage capacity in extreme weather conditions (such as heavy rain), allowing rainwater to seep into the cabinet and disrupt the normal operation of internal components. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of the existing technology and provide a drainage structure for power distribution cabinets.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a drainage structure for a power distribution cabinet, comprising: a box body, a roof mechanism fixedly connected to the upper end of the box body, an inner cavity opened on both sides of the inner wall of the box body, a drain pipe fixedly connected to one side of the inner wall of the inner cavity, and a heat-conducting inner wall connected to one side of the inner wall of the drain pipe. The canopy mechanism includes a canopy body fixedly connected to the upper end of the box. Drainage channels are provided on both outer walls of the upper end of the canopy body, and connecting grooves are provided on both inner walls of the canopy body. A first filter screen is connected to one side of the drainage channel, and the first filter screen is correspondingly connected to one side of the inner wall of the connecting groove.

[0006] In a preferred embodiment, a connecting shaft is connected to one outer wall of the box body, a cabinet door is movably connected to one side of the connecting shaft, a handle is fixedly connected to one outer wall of the cabinet door, a support foot is fixedly connected to the lower outer wall of the box body, heat dissipation pipes are provided on both sides of the upper end of the box body, a second filter screen is connected to one side of the inner wall of the heat dissipation pipe, and a fan is fixedly connected to the top of the inner wall of the box body.

[0007] In a preferred embodiment, five heat dissipation pipes are provided on both sides of the upper end of the housing, and a second filter screen is provided on one side of the inner wall of each of the five heat dissipation pipes.

[0008] In a preferred embodiment, the upper end of the heat dissipation pipe is connected to the lower end of the ceiling body.

[0009] In a preferred embodiment, the upper end of the drain pipe provided on the inner wall of the inner cavity is connected to the connecting groove opened on the inner wall of the ceiling body, and the lower end of the drain pipe is connected to the bottom end of the outer wall of the box body.

[0010] In a preferred embodiment, the fan located at the top of the inner wall of the housing is connected to the heat dissipation pipes located on both sides of the housing.

[0011] In a preferred embodiment, the heat-conducting inner wall is fixedly connected to the outer wall of the box via a drain pipe provided inside the inner cavity.

[0012] In a preferred embodiment, the heat dissipation pipes on both sides of the housing are misaligned with the connecting grooves on the inner wall of the roof body.

[0013] Compared with the prior art, the advantages and positive effects of this utility model are as follows: 1. When this utility model is in use, the design of the drainage channel and connecting groove of the canopy body allows rainwater to enter the drainage pipe after passing through the filter screen, and then be dispersed into the box body through the inclined pipe, effectively filling the heat-conducting inner wall, realizing efficient drainage and heat exchange. The heat-conducting inner wall made of SMC composite material not only has excellent mechanical strength and corrosion resistance, but also has thermal conductivity, further improving the heat dissipation effect.

[0014] 2. When in use, one end of the heat dissipation pipe extends outside the box and the other end is connected to the internal components. The fan, in conjunction with the heat dissipation pipe design, quickly dissipates the heat generated by the internal components of the box, achieving efficient heat dissipation. The canopy body is wider than the box body, forming a good shielding effect to prevent rainwater and external factors from affecting heat dissipation and internal components.

[0025] like Figure 1-4 As shown, this utility model provides a technical solution: a drainage structure for a power distribution cabinet, including: a box body 1, a canopy mechanism 6 fixedly connected to the upper end of the box body 1, an inner cavity 7 opened on both sides of the inner wall of the box body 1, a drain pipe 8 fixedly connected to one side of the inner wall of the inner cavity 7, a heat-conducting inner wall 9 connected to one side of the inner wall of the drain pipe 8, and the heat-conducting inner wall 9 and the outer wall of the box body 1 fixedly connected through the drain pipe 8 provided in the inner cavity 7; The roof mechanism 6 includes a roof body 61 fixedly connected to the upper end of the box body 1. Drainage channels 62 are provided on both outer walls of the upper end of the roof body 61, and connecting grooves 63 are provided on both inner walls of the roof body 61. The upper end of the drain pipe 8 provided on the inner wall of the inner cavity 7 is connected to the connecting groove 63 provided on the inner wall of the roof body 61, and the lower end of the drain pipe 8 is connected to the bottom of the outer wall of the box body 1. A first filter screen 64 is connected to one side of the drain channel 62, and the first filter screen 64 is connected to one side of the inner wall of the connecting groove 63. The heat dissipation pipes 10 provided on both sides of the box body 1 are misaligned with the connecting grooves 63 provided on the inner wall of the roof body 61.

[0026] In this embodiment, a housing 1 is designed with inner cavities 7 on both sides of the inner wall of the housing 1. A drain pipe 8 is fixedly connected to one side of the inner wall of the inner cavity 7. The drain pipe 8 has an array of pipes equal in number to the connecting grooves 63 opened on the inner wall of the canopy body 61, and each pipe is connected to the connecting groove 63. A transverse pipe with an inclined angle is provided between these pipes. Therefore, when rainwater is drained through the drainage channel 62 opened at the upper end of the canopy body 61, some of it will pass through the first filter screen 64 and enter the drain pipe 8 connected to the connecting groove 63. At this time, the drain pipe 8 will disperse this rainwater and fill one side of the inner wall of the housing 1. A heat-conducting inner wall 9 is provided on one side of the drain pipe 8 and one side of the inner wall of the housing 1. The heat-conducting inner wall 9 is made of SMC composite material, which is a high-performance composite material composed of glass fiber, unsaturated polyester resin, etc. This material not only has good mechanical strength and corrosion resistance, but also has certain thermal conductivity. In the housing 1, the heat-conducting inner wall 9 made of SMC composite material is connected to the drain pipe 8, which can achieve efficient heat exchange and heat dissipation. Thus, the housing 1 can dissipate heat while draining water. The top of the roof body 61 is inclined, and the drainage channel 62 on its outer wall is also inclined. The two sides of the roof body 61 are wider than the overall housing 1. Therefore, under normal circumstances, rainwater can be discharged directly to the outside of the housing 1 through the drainage channel 62. A small amount of rainwater will enter the drain pipe 8 through the connecting groove 63 to achieve heat exchange. The first filter screen 64 can prevent some large particles or impurities from entering the drain pipe 8 and causing blockage, which would prevent heat dissipation and drainage. Example

[0027] like Figure 1-3 As shown, a connecting shaft 2 is connected to one side of the outer wall of the box body 1, a cabinet door 3 is movably connected to one side of the connecting shaft 2, a handle 4 is fixedly connected to one side of the outer wall of the cabinet door 3, a support foot 5 is fixedly connected to the lower outer wall of the box body 1, heat dissipation pipes 10 are provided on both sides of the upper end of the box body 1, the upper end of the heat dissipation pipes 10 is correspondingly connected to the lower end of the ceiling body 61, a second filter screen 11 is connected to one side of the inner wall of the heat dissipation pipes 10, five heat dissipation pipes 10 are provided on both sides of the upper end of the box body 1, and a second filter screen 11 is provided on one side of the inner wall of each of the five heat dissipation pipes 10, a fan 12 is fixedly connected to the top of the inner wall of the box body 1, and the fan 12 at the top of the inner wall of the box body 1 is correspondingly connected to the heat dissipation pipes 10 on both sides of the box body 1.

[0028] In this embodiment, a cabinet door 3 is connected to one outer wall of the housing 1 via a connecting shaft 2. A handle 4 is connected to one outer wall of the cabinet door 3. By gripping the handle 4, the cabinet door 3 can be rotated around the connecting shaft 2, thereby opening the interior of the housing 1. At this time, the electronic components inside the housing 1 can be repaired. A fan 12 is provided at the top of the inner wall of the housing 1, and five heat dissipation pipes 10 are provided at the upper ends of both sides of the housing 1. A second filter screen 11 is provided on one side of the inner wall of each of the five heat dissipation pipes 10. One end of the heat dissipation pipe 10 extends to the outer wall of the housing 1, and the other end extends to the housing. The inner wall is designed so that when it is in operation, the internal components will generate heat. At this time, the fan 12 is turned on, and the fan 12 will exhaust the heat through the heat dissipation pipe 10, thereby dissipating heat. The second filter screen 11 can prevent external impurities from being sucked into the box 1 through the air recirculation, thereby affecting the internal electronic components. The upper end of the heat dissipation pipe 10 is close to the lower end of the roof body 61, and the roof body 61 extends to one side of the box 1. Therefore, when it is windy and rainy, rainwater will be affected by the roof body 61 and will not enter the heat dissipation pipe 10, further ensuring the heat dissipation effect.
