Abstract
Description
Technical Field
[0001] This invention relates to the field of power distribution cabinet technology, and specifically to an outdoor protective power distribution cabinet. Background Technology
[0002] A distribution cabinet, also known as a distribution box, is a type of distribution cabinet installed outdoors. Outdoor usage scenarios are diverse and complex, and most outdoor distribution boxes currently have heat dissipation and ventilation structures, or use cooling fans in conjunction with these structures for heat dissipation.
[0003] However, during the rainy season, in damp areas near water, or in mountainous forests, the air humidity is high. Moisture can seep in through the heat dissipation and ventilation structures, which can easily damage internal electrical components. Even if a fan is installed, its main function is to dissipate heat, but the airflow will still increase the internal humidity, making it impossible to achieve the desired moisture-proof and drying effect.
[0004] In summary, considering that outdoor power distribution cabinets need to have active moisture-proof and drying functions to obtain a good operating environment for outdoor power distribution cabinets, which is conducive to reducing the failure rate and extending the maintenance cycle of power distribution cabinets; therefore, we propose an outdoor protective power distribution cabinet. Summary of the Invention
[0005] The purpose of this invention is to address the shortcomings mentioned in the background section and provide an outdoor protective power distribution cabinet.
[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0008] The heat dissipation and moisture-proof section includes side guide units installed on both sides of the power distribution cabinet, and the side guide units are equipped with a drying unit that can be lifted and installed.
[0009] The drying unit is provided with a stretching component, which includes a connecting strip connected to the drying unit at one end and a movable first conductive block connected to the other end of the connecting strip.

[0012] Preferably, the drying unit includes a drying hood inserted inside the L-shaped guide tube and corresponding to the position of the airflow plate. The drying hood has through holes, and a drying silica gel plate is detachably installed inside the drying hood.
[0013] Preferably, the drying hood is rotatably mounted with symmetrically arranged bearings, and the inner wall of the L-shaped guide tube is provided with a vertical sliding groove for inserting the bearings.
[0014] Preferably, a heat-conducting baffle is installed between the two L-shaped guide pipes, and the heat-conducting baffle is provided with heat dissipation aluminum fins;
[0015] A cabinet top sealing plate is installed above the heat-conducting baffle, and the cabinet top sealing plate is provided with a mounting groove for installing the cooling fan.
[0016] Preferably, the connecting belt is connected to the first conductive block via a first limiting roller and a second limiting roller that are rotatably mounted, and the first conductive block is electrically connected to a wire.

[0036] The technical solutions of the present invention will be clearly and completely described below with reference to the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. Unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0037] Please see Figure 1-6 The present invention will describe the above technical solution in detail through the following embodiments:
[0038] An outdoor protective distribution cabinet includes a cabinet body 1 with a cabinet door 2 installed, and further includes:
[0039] The heat dissipation and moisture protection section includes side guide units 3 installed on both sides of the power distribution cabinet 1, and a drying unit 8 that can be lifted and installed is provided in the side guide unit 3.
[0040] The drying unit 8 is provided with a stretching component, which includes a connecting strip 13 connected to the drying unit 8 at one end, and a movable first conductive block 14 connected to the other end of the connecting strip 13.
[0041] The cooling fan 5 is positioned on the moving path of the first conductive block 14 and is used to contact the first conductive block 14 for energizing.
[0042] like Figure 1-2 The structure shown includes a ventilation socket 101 on the distribution cabinet 1, and a side airflow guiding unit 3 comprising an L-shaped airflow guiding pipe 31 installed at the ventilation socket 101; as shown Figure 3-4 As shown in the structure, in this embodiment, a ventilation plate 32 is installed at the outer opening of the L-shaped guide pipe 31, and an airflow plate 33 is installed inside the distribution cabinet 1 of the L-shaped guide pipe 31. The airflow plate 33 is mainly used to exchange air with the internal space and obtain an airflow path.
[0043] like Figure 6 As shown, the drying unit 8 includes a drying hood 81 inserted in the L-shaped guide tube 31 and corresponding to the position of the airflow plate 33. The drying hood 81 is provided with a through hole 811, and a drying silica gel plate 82 is detachably installed inside the drying hood 81. The drying silica gel plate 82 can absorb water and can achieve drying under the action of flowing air or heating.
[0044] like Figure 4 and Figure 6 As shown in the structure, the drying hood 81 is rotatably mounted with symmetrically arranged bearings 83, and the inner wall of the L-shaped guide tube 31 is provided with a vertical sliding groove 311 for inserting the bearings 83. The bearings 83 can reduce friction and improve the sensitivity of movement.
[0045] like Figure 2-4 The structure shown has a heat-conducting baffle 7 installed between the two L-shaped guide pipes 31. The heat-conducting baffle 7 is provided with heat dissipation aluminum fins 71, mainly for absorbing heat and facilitating heat dissipation. A cabinet top sealing plate 4 is installed above the heat-conducting baffle 7. The cabinet top sealing plate 4 is provided with a mounting groove 401 for installing the cooling fan 5. It should be noted that in this embodiment, the cooling fan 5 is connected to a temperature sensor in parallel through a wire. The start and stop of the cooling fan 5 are controlled by the temperature. This technology is existing technology and will not be described in detail. In this embodiment, a rainproof cover 6 is installed on the cabinet top sealing plate 4.
[0046] like Figure 4-5The structure shown includes a stretching assembly with one end connected to a connecting belt 13 on a drying hood 81. The other end of the connecting belt 13 is connected to a first conductive block 14 via a first limiting roller 11 and a second limiting roller 12 that are rotatably mounted. A wire 16 is electrically connected to the first conductive block 14. A spring 15 is insulated between the first conductive block 14 and the distribution cabinet 1. A second conductive block 17 is mounted on the cooling fan 5 to form a closed circuit with the first conductive block 14. When the ambient humidity is high, the drying silica gel plate 82 absorbs water and becomes heavier, causing the connecting belt 13 to pull the spring 15 to extend.
[0047] like Figure 5 The structure shown has six layers of staggered condensate plates 9 installed inside the L-shaped guide pipe 31 and below the drying unit 8 to collect droplets and guide them downwards; at the same time, a guide plate 10 is provided inside the L-shaped guide pipe 31 below the condensate plates 9, and a drain port 312 for discharging droplets is provided outside the distribution cabinet 1 of the L-shaped guide pipe 31.
[0048] The working principle of the outdoor protective power distribution cabinet in this embodiment is as follows: When the ambient humidity is high, the humid air will enter the drying hood 81 through the L-shaped guide pipe 31. At the same time, the humid air inside the cabinet will also come into contact with the drying silicone plate 82 through the airflow plate 33. The drying silicone plate 82 absorbs water and its weight increases. The connecting belt 13 pulls the spring 15 to extend, which drives the first conductive block 14 to move until it contacts the second conductive block 17 to form a closed circuit. At this time, the cooling fan 5 starts, the airflow flows, and the internal airflow is discharged to achieve drying. The airflow will carry away the moisture, so that the drying silicone plate 82 dries. After the drying quality decreases, the spring 15 returns to its original position, the circuit is broken, and the cooling fan 5 stops.
[0049] It should be noted that if the embodiments of the present invention involve directional indications (such as up, down, left, right, front, back, etc.), the directional indications are only used to explain the relative positional relationship and movement of the components in a specific posture. If the specific posture changes, the directional indications will also change accordingly.
[0050] Furthermore, if the embodiments of the present invention involve descriptions such as "first" or "second," such descriptions are 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. Thus, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature.
[0051] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the invention. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within the present invention.
