[0002] A distribution cabinet is a device used in the power system for managing and distributing power supply. It usually consists of one or more power switches and other electrical devices for controlling, protecting, and distributing electrical energy to different electrical devices or circuits.

[0003] In the harsh environment of oil extraction, especially in remote areas such as deserts and gobi far from urban areas, the heat dissipation and protection problems of the same type of skid-mounted and cabinet bodies are particularly prominent. These devices need to simultaneously meet the heat dissipation requirements and effectively resist the invasion of rainwater and prevent the entry of sand and dust. However, existing technologies often struggle to strike a balance between the two. Their sand prevention mainly uses filter cotton to block sand from entering the cabinet body, but after blocking the sand, the air permeability of the filter cotton will decrease, affecting heat dissipation. Therefore, it needs to be cleaned frequently. However, in remote areas such as deserts and gobi, maintenance and cleaning work are extremely inconvenient. The lack of manpower and materials makes every maintenance and cleaning a difficult task. This not only increases the loss of manpower and financial resources but also may lead to delays in the production schedule, having an adverse impact on oil extraction work. Summary of the Invention

[0029] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0030] Example

[0031] like Figure 4 As shown, a cabinet disclosed in an embodiment of the present application includes: a side wall plate 100 as a side wall of the cabinet, wherein one or more side wall plates 100 are provided with a second direction ( Figure 4 A plurality of groups of vent holes 101 are arranged in a first direction (Y direction), each of which includes a plurality of vent holes arranged in a first direction ( Figure 4Vent holes are provided at intervals in the X direction (in the figure). The vent hole group 101 includes a plurality of vent holes that penetrate through the side wall plate 100 and are used to communicate the inside and outside of the cabinet at the side wall plate 100 to achieve a ventilation effect, enabling the hot air inside the cabinet and the cold air outside to flow alternately, realizing the heat dissipation function of the cabinet. Multiple vent hole groups 101 are provided, so that a plurality of vent holes are dispersedly distributed on the side wall plate 100 to ensure the air circulation effect and thus ensure the heat dissipation effect of the cabinet. On the side of the side wall plate 100 facing the inside of the cabinet, a plurality of sand prevention members are provided. The sand prevention members extend along the first direction, and a plurality of sand prevention members are arranged at intervals along the second direction. The sand prevention members correspond to the vent hole groups 101 one by one. The sand prevention members are used to block sand and wind from entering the inside of the cabinet, and each sand prevention member corresponds to a group of vent hole groups 101.

[0032] As Figure 5 shown, specifically, the sand prevention member includes a first sand prevention strip 201, a second sand prevention strip 202, and a third sand prevention strip 203. The first sand prevention strip 201, the second sand prevention strip 202, and the third sand prevention strip 203 are sequentially connected to each other, and the first sand prevention strip 201, the second sand prevention strip 202, and the third sand prevention strip 203 enclose a sand prevention area with an opening.

[0033] The first sand prevention strip 201, the second sand prevention strip 202, and the third sand prevention strip 203 are all arranged along the direction in which the vent hole group 101 is provided, that is, along the first direction. The sand prevention area formed by the corresponding connection of the first sand prevention strip 201, the second sand prevention strip 202, and the third sand prevention strip 203 completely covers each vent hole of the corresponding vent hole group 101, and the shape of the sand prevention area is similar to a C-shaped return shape with three sides blocked and one side open.

[0034] Among them, the third sand prevention strip 203 is connected to the cabinet side wall plate 100. There is a ventilation gap between the first sand prevention strip 201 and the side wall plate 100, and the opening of the sand prevention area is aligned with the plurality of vent holes in the corresponding vent hole group 101.

[0035] The third sand prevention strip 203, the second sand prevention strip 202, and the first sand prevention strip 201 are arranged from bottom to top in sequence. The opening of the sand prevention area formed by the first sand prevention strip 201, the second sand prevention strip 202, and the third sand prevention strip 203 faces the vent hole, but the two are staggered rather than completely aligned. As a result, the ventilation gap between the first sand prevention strip 201 and the side wall plate 100 is located above the vent hole. In this way, the air entering through the vent hole will not directly enter the inside of the cabinet through the ventilation gap. Instead, the air will pass through the return-shaped area formed by the sand prevention area and then enter the inside of the cabinet through the ventilation gap. During this process, the air will be forced to change direction and flow upward, and at the same time, it will be decelerated by the return shape formed by the sand prevention area. Under the influence of gravity, the sand and soil in the air will stay in the sand prevention area, thus preventing the sand and soil from directly entering the inside of the cabinet.

[0036] Specifically, during operation, when the air with sand and dust outside the cabinet body enters the sand prevention area through the air vents, the air will first contact and rebound against the first sand prevention strip 201, the second sand prevention strip 202, or the third sand prevention strip 203 in the sand prevention area to change its direction. Then, after changing directions multiple times, it will flow towards the permeable gaps where it can circulate and then enter the cabinet body. During this process, while the air is blocked and its direction is changed by the first sand prevention strip 201, the second sand prevention strip 202, and the third sand prevention strip 203, the flow rate of the air is also reduced. Therefore, the sand and dust in the air will stay in the sand prevention area under the action of gravity, thus achieving the sand prevention effect of the cabinet body.

[0037] During this process, while the air is blocked and its direction is changed by the first sand prevention strip 201, the second sand prevention strip 202, and the third sand prevention strip 203, the flow rate of the air is also reduced. Therefore, the sand and dust in the air will stay in the sand prevention area under the action of gravity, thus achieving the sand prevention effect of the cabinet body.

[0038] In an alternative embodiment, the materials of the first sand prevention strip 201, the second sand prevention strip 202, and the third sand prevention strip 203 are galvanized sheets;

[0039] The width of the permeable gap is 6 mm, the distance between the second sand prevention strip 202 and the side wall plate 100 of the cabinet body is 14.5 mm, the width of the second sand prevention strip 202 is 13 mm, and the angle between the second sand prevention strip 202 and the third sand prevention strip 203 is 115 degrees.

[0040] As Figure 5 shown, further, in order to prevent the sand and soil in the sand prevention area from accumulating in the sand prevention area and blocking the air vents, the third sand prevention strip 203 is inclined, and the lowest part of the third sand prevention strip 203 is located at the connection between the third sand prevention strip 203 and the side wall plate 100, so that the third sand prevention strip 203 inclines downward from the side connecting the second sand prevention strip 202 to the side connecting the side wall plate 100. In this way, when the sand and soil staying in the sand prevention area falls on the third sand prevention strip 203, it will slide out of the sand prevention area and the air vents along the inclined direction of the third sand prevention strip 203, realizing the function of automatically discharging the sand and soil.

[0041] As Figure 1 shown, further, in order to seal both ends of each sand prevention part and prevent the wind and sand from entering the cabinet body from both ends of the sand prevention part, support strips 301 are commonly provided at both ends of each sand prevention part. The support strips 301 can block both ends of the sand prevention part, so that the air can only enter the cabinet body through the permeable gap between the first sand prevention strip 201 and the side wall plate 100, ensuring the sand prevention effect.

[0042] As Figure 1As shown in the figure, further, in order to prevent bugs from entering the interior of the cabinet and affecting various electrical components, an insect-proof net 302 is also provided between the two support bars 301, and the insect-proof net 302 is located on the side of the sand-proof member away from the side wall plate 100. The insect-proof net 302 is used to isolate bugs. After the bugs enter the inner side of the side wall plate 100 through the air holes and pass through the air-permeable gap between the first sand-proof strip 201 and the side wall plate 100, they will be blocked by the insect-proof net 302 and thus cannot continue to move towards the interior of the cabinet, preventing the bugs from contacting the electrical components in the cabinet and realizing the function of insect prevention. At the same time, when air enters the interior of the cabinet, there may be some relatively light sand residues in the air, and the insect-proof net 302 can also filter out this part of the sand, further enhancing the sand-proof effect of the cabinet. And because it is a small amount of sand, it is not necessary to clean the insect-proof net 302 frequently, and the ventilation effect at the insect-proof net 302 can also be ensured. Just clean it together when maintaining and cleaning the electrical equipment

[0043] It can be cleaned together, without adding additional cleaning burden.

[0044] As Figure 1 shown in the figure, further, in order to facilitate the removal and cleaning of the insect-proof net 302, the insect-proof net 302 is slidably arranged between the two support bars 301, and a support frame 303 for supporting the insect-proof net 302 is sleeved around the periphery of the insect-proof net 302;

[0045] At the same time, in order to carry the insect-proof net 302 and ensure that the insect-proof net 302 can stand upright between the two support bars 301, a pocket plate 304 is arranged on the side of the support bar away from the side wall plate, so that the support bar 301 and the pocket plate 304 can form a sliding groove for the support frame 303 supporting the insect-proof net 302 to slide.

[0046] When maintaining and cleaning the insect-proof net 302, slide the support frame 303 out of the sliding groove, and the insect-proof net 302 can be taken out together. Then the insect-proof net 302 can be taken to an open area for cleaning, avoiding cleaning operations in the narrow space inside the cabinet and facilitating the cleaning operation.

[0047] As Figure 2 shown in the figure, further, in order to support and limit the positions of the support frame 303 and the insect-proof net 302, a support piece 305 for supporting the support frame 303 is arranged at the lower end of the pocket plate 304. When the support frame 303 slides to contact the support piece 305 and is supported by the support piece 305, the position of the insect-proof net 302 just aligns with each sand-proof member that can circulate air, ensuring the isolation effect of the insect-proof net 302.

[0048] Further, in order to facilitate the cleaning of the sand prevention area formed by the first sand prevention strip 201, the second sand prevention strip 202, and the third sand prevention strip 203 of the sand prevention component during maintenance cleaning, prevent the accumulation of sand and soil at non-ventilation hole positions in the sand prevention area, the support strip 301 is connected to the cabinet side wall plate 100 by bolts 306, so that the support strip 301 can be disassembled;

[0049] When it is necessary to clean the sand prevention area, the support strip 301 can be removed, so that both ends of the sand prevention component are opened, and then a long rod with a brush can be used to clean the sand prevention area, which is convenient for cleaning the sand prevention component.

[0050] Such as Figure 3 and Figure 4 As shown, further, in order to prevent rainwater from entering the ventilation holes, the cabinet side wall plate 100 is provided with a waterproof cover 102 at the position of each ventilation hole, and the waterproof cover 102 is arranged on the side of the cabinet side wall plate 100 away from the sand prevention component, and the waterproof cover 102 covers the upper part of the ventilation hole, so that when it rains, the rainwater will fall on the waterproof cover 102 and will not directly fall into the ventilation hole.

[0051] Further, in order to prevent rainwater from flowing into the ventilation holes, the waterproof cover 102 is arranged in an arc shape, and the waterproof cover 102 extends downward to guide the rainwater to flow downward and leave the ventilation hole, ensuring the rain prevention effect.

[0052] This application is aimed at harsh environments such as deserts and gobi, and cleverly solves the multiple problems of rain prevention, sand prevention, mosquito prevention, and ventilation and heat dissipation that are difficult to balance in traditional products. By setting sand prevention components corresponding to each ventilation hole group and carefully designing the shape of the sand prevention components, sand and wind can be discharged from the cabinet by themselves. By setting the waterproof cover 102 and the insect net 302, significant effects of rain prevention, sand prevention, and mosquito prevention are achieved, and almost completely prevent the intrusion of sand and dust, rainwater, and mosquitoes. This design innovation not only fully protects the safety and stable operation of the electrical facilities inside the cabinet, effectively extends the service life, but also greatly reduces the tediousness and inconvenience of manually cleaning the inside of the cabinet.

[0053] It should be noted that the various embodiments in this specification are described in a progressive manner. Each embodiment focuses on the differences from other embodiments. The same or similar parts between the various embodiments can be referred to each other.
