Description

Technical Field

[0001] The utility model relates to the technical field of switch cabinets, and specifically relates to a switch cabinet with a ventilation cover that is convenient to replace. Background Technique

[0002] For traditional switch cabinets, in order to ensure the working environment of electrical components inside the cabinet, ventilation openings are usually provided on the cabinet body to ensure air circulation and prevent equipment failures caused by overheating. However, during actual use, due to the influence of the external environment, pollutants such as dust and moisture are likely to enter the cabinet through the ventilation openings, which not only affects the normal operation of electrical components but also may pose potential safety hazards. Therefore, a ventilation cover is usually provided at the ventilation opening to block these pollutants.

[0003] At present, the connection method between most ventilation covers on the market and switch cabinets is relatively fixed, and it is inconvenient to disassemble, which brings great difficulties to daily cleaning and maintenance work. Once the filter screen on the ventilation cover is severely dusty and needs to be cleaned or replaced, tools are often required, consuming a lot of time and manpower. In addition, due to the complex structure of the ventilation cover, when it is necessary to locally replace the filter screen, the whole set is often replaced because of the cumbersome disassembly and assembly, increasing the maintenance cost.

[0004] In view of the above problems, a switch cabinet with a ventilation cover that is convenient to replace is proposed. This device can achieve the quick disassembly and assembly of the ventilation cover assembly, allowing the filter screen inside the ventilation cover to be replaced separately, thereby improving the maintenance efficiency and reducing the maintenance cost.

[0005] Aiming at the deficiencies in the background technique, the utility model provides a switch cabinet with a ventilation cover that is convenient to replace.

[0006] The technical solution adopted by the utility model is: a switch cabinet with a ventilation cover that is convenient to replace, including a cabinet body. There are ventilation openings on the side wall of the cabinet body. It also includes a ventilation cover assembly. A "U"-shaped mounting frame is welded on the outer ring of the ventilation opening. "T"-shaped connecting grooves are provided on both sides of the mounting frame. The ventilation cover assembly includes a "U"-shaped wind cover housing, a plurality of filter screens detachably arranged inside the wind cover housing, and a wind cover lid covering the wind cover housing. "T"-shaped connecting heads that are slidably matched with the "T"-shaped connecting grooves are provided on both sides of the wind cover housing and both sides of the wind cover lid.

[0007] Furthermore, a row of quick connecting blocks is provided on both sides of the wind cover housing. "V"-shaped grooves are provided on the quick connecting blocks. "V"-shaped connecting heads that are slidably matched with the above "V"-shaped grooves are provided at both ends of the filter screen.

[0008] Furthermore, the filter screen includes a metal mesh arranged on the outside and a moisture-proof mesh arranged on the inside.

DETAILED DESCRIPTION

[0021] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0022] It should be noted that if there are directional indications (such as up, down, left, right, front, back...) involved in the embodiments of the present utility model, the directional indications are only used to explain the relative position relationship and movement conditions between components in a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indications will also change accordingly.

[0023] The present utility model provides a switch cabinet that facilitates the replacement of a ventilation cover.

[0024] In this embodiment, referring to Figure 1-3 , the switch cabinet that facilitates the replacement of a ventilation cover includes a cabinet body 1. A ventilation opening 2 is provided on the side wall of the cabinet body 1. It further includes a ventilation cover assembly. An "L"-shaped mounting frame 3 is welded to the outer circle of the ventilation opening 2. "T"-shaped connection grooves 4 are provided on both sides of the mounting frame 3. The ventilation cover assembly includes an "L"-shaped wind cover housing 5, a plurality of cover meshes 6 detachably arranged inside the wind cover housing, and a wind cover 7 covering the wind cover housing 5. "T"-shaped connection heads 8 that are slidably matched with the "T"-shaped connection grooves 4 are provided on both sides of the wind cover housing 5 and both sides of the wind cover.

[0025] In the above technical solution, by welding an "L"-shaped mounting frame to the outer circle of the ventilation opening and providing "T"-shaped connection grooves on both sides of the mounting frame, the ventilation cover assembly can be quickly plugged and unplugged through the "T"-shaped connection heads, greatly improving the disassembly and assembly efficiency of the ventilation cover assembly and facilitating maintenance.

[0026] In addition, since the ventilation cover assembly adopts a modular design, the cover mesh can be flexibly replaced or cleaned according to actual needs without replacing the entire ventilation cover, reducing the maintenance cost.

[0027] Specifically, a row of quick connection blocks 9 are provided on both sides of the wind cover housing. "V"-shaped grooves 10 are provided on the quick connection blocks 9. "V"-shaped connection heads 11 that are slidably matched with the above "V"-shaped grooves 10 are provided at both ends of the cover mesh.

[0028] In this embodiment, by providing a row of quick connection blocks with "V"-shaped grooves on both sides of the wind cover housing and "V"-shaped connection heads that are slidably matched with them at both ends of the cover mesh, this design makes the installation of the cover mesh more stable, reducing displacement caused by vibration or air flow impact.

[0029] Specifically, the cover net includes a metal net 12 arranged on the outside and a moisture-proof net 13 arranged on the inside.

[0030] In this embodiment, by arranging a metal mesh on the outside and a moisture-proof mesh on the inside, it can not only effectively block dust and other impurities from entering the cabinet, but also prevent moisture from corroding electrical components, providing double protection and extending the service life of the equipment.

[0031] The combination of metal mesh and moisture-proof net enhances the protective performance of the ventilation hood and ensures the stable operation of electrical equipment in harsh environments. In addition to connecting the metal mesh and moisture-proof net, you can also connect a sound insulation net or a filter net, or connect nets with different functions for different environments. For example, in an industrial environment, you can add an anti-static net; in a kitchen or catering place, you can add a grease filter; in a chemical laboratory, you can use a chemical resistant net, etc. This can better meet the specific needs of different application scenarios.

[0032] Specifically, there are four quick connection blocks 9 on one side of the wind shield shell.

[0033] like Figure 3 As shown, there are four quick connection blocks in a row, which can fix four cover nets of different functions, or only connect one or more cover nets. This design allows the ventilation hood assembly to have multiple protection functions. For example, a dustproof net can be set on the outside, a moisture-proof net can be set on the inside, and a soundproof net or filter net can be set in the middle to meet the protection needs in different environments.

[0034] Specifically, four corners on the top of the cabinet are threadedly connected with hanging rings 14 .

[0035] In this embodiment, threaded lifting rings are provided on the four corners of the top of the cabinet, so that the switch cabinet can be lifted by lifting equipment during transportation, which not only improves the safety of transportation but also reduces the burden of manual transportation. The existence of the lifting ring is not limited to transportation, but can also be used to fix the equipment to keep it stable in a specific environment, increasing the versatility of the equipment.

[0036] Specifically, a fan cover opening 15 is provided on the top of the cabinet, a fan cover 16 is fixed to the fan cover opening 15 by bolts, and a plurality of ventilation slots 17 are evenly spaced on the side wall of the fan cover 16 .

[0037] In this embodiment, a fan cover is provided on the top of the cabinet, and the fan cover is fixed by bolts. The ventilation slots on the side wall of the fan cover can effectively increase the air flow, further improving the heat dissipation conditions inside the cabinet. In addition, the fan cover can be fixed by bolts, making it very convenient to disassemble and assemble the fan cover, which is convenient for regular inspection and cleaning of the fan to ensure its normal operation, and also convenient for inspection and maintenance inside the cabinet.

[0038] Technical personnel should note: Although the utility model has been described according to the above specific implementation methods, the concept of the utility model is not limited to this utility model. Any modification using the concept of the utility model will be included in the scope of protection of this patent right.
