Description

Outdoor cabinet waterproof device

technical field

The utility model relates to a waterproof device for outdoor communication equipment.

Background technique

With the rapid development of science and technology, the types and quantities of outdoor communication equipment are increasing, and the application environment is becoming wider and more complex. According to IEC standards, outdoor communication equipment must at least meet the IP54 or IP55 enclosure protection level to ensure the safety of equipment and personnel. Table 1 lists the relevant parameters (parts) of the protection level, and the full content can be found in GB 4208 and GJB1440.

Table 1: Protection class and requirements performance level Protection category meaning Basic Design Requirements IP54 Dustproof, splashproof Dustproof: It cannot completely prevent dust from entering, but the amount of dust entering must not affect the normal operation of the equipment and must not affect safety. Protection against splashing water: Water splashed against the enclosure from any direction will have no harmful effect. 1. The enclosure shall not have any exposed openings. 2. The door, cover and separation surface of the casing should have gaskets. 3. The casing material should not be damaged by swelling, peeling, deformation, etc. 4. The protective layer on the surface of the casing should not be blistered, cracked or peeled off. 5. The equipment should be designed with drainage holes. IP55 Dust-proof, water-spray-proof Dust-proof: meet the requirements of water spraying, and the equipment does not meet the requirements of solid foreign objects (including dust). Protection against water jets: Water sprayed against the enclosure from any direction will have no harmful effect.

Table 1 shows that preventing jet water from entering the cabinet is the key to the protection of outdoor cabinets. In the current outdoor cabinet protection, the protection is mainly achieved by fully sealing the cabinet. The difficulty of waterproofing the fully sealed outdoor cabinet lies in the air conditioner (heat exchanger), the air inlet and outlet of the air conditioner, because there are vents such as louvers, there will be rain splashing In order to prevent more rainwater from entering the air-conditioning cabin, a curved structure is generally designed in the vent to change the direction of the air duct and prevent rainwater from entering. At the same time, it is designed to discharge the rainwater that may enter. However, the seal and bend design not only cannot completely prevent the entry of water and moisture, but also increase the difficulty and workload of the protection design.

Utility model content

The technical problem to be solved by the utility model is to provide a new waterproof device for outdoor cabinets in order to overcome the unreliable waterproof performance of outdoor cabinets in the prior art, and to solve the problems of moisture and rainwater in the prior art on the performance of outdoor cabinets. Negative impact.

The technical solution adopted by the utility model is: the outdoor cabinet waterproof device includes waterproof louvers, ventilation meshes, and waterproof louver structure mounting parts. The ventilation meshes can ensure effective ventilation inside and outside the cabinet. The waterproof louvers adopt a labyrinth sheet metal structure, The two ends of the waterproof louver are connected and fixed with the waterproof louver structure mounting parts and then connected to the ventilation mesh. The waterproof louver structure mounting parts are used to realize the connection between the waterproof louver blades.

The waterproof louvers of the present utility model are preferably connected with the waterproof louver structural mounting parts by welding, and the waterproof louvers and the ventilation meshes are preferably connected by screws.

The waterproof louver system described in the above scheme is composed of a plurality of waterproof louver blades shaped like an oblique "S" in parallel and closely combined to form a labyrinth sheet metal structure, so as to ensure that water jets from all directions at the external circulation air duct will not enter the inside of the cabinet. Water spray reflection, waterproof louvers can complete the waterproof function well, and its ventilation area is large, and the ventilation effect is good.

The bottom surface of the waterproof louvers is composed of an inclined surface and a horizontal platform. There are long drainage slits on the horizontal platform to realize the automatic drainage function. The inclined surface can make a small amount of water droplets entering the module quickly enter the horizontal platform along the slope. The long drainage slit flows into the bottom drainage hole to discharge the cabinet. The horizontal platform not only ensures the accurate confluence of water droplets, but also realizes the flat contact between the waterproof module and the front door liner to ensure reliable contact.

The beneficial effects of the utility model are: compared with the prior art, the device described in the utility model adopts a labyrinth sheet metal structure. The utility model can not only completely prevent the jet water from entering the cabinet, but also has a simple and convenient structure, and the outdoor cabinet is waterproof. The performance is improved, the ventilation effect is improved, and the drainage performance is improved, which achieves the effect of preventing jet water from entering the outdoor cabinet, completely solves the problem of water entering the air inlet and outlet of the outdoor cabinet, and saves the cost and workload spent on waterproof protection of the outdoor cabinet. Improve the reliability of the outdoor cabinet. The utility model has good waterproof performance, is simple and convenient to use, and is especially suitable for outdoor cabinets that work in harsh environments for a long time.

Detailed ways

The implementation of the technical solution will be further described in detail below with reference to the accompanying drawings. In this embodiment, the device is installed at the air inlet of the front door of the cabinet to play the role of uniform air volume.

As shown in Figure 1, the outdoor cabinet waterproof device includes a waterproof louver 1, a ventilation mesh 2, and a waterproof louver structure mounting part 3. The waterproof louver 1 is composed of a plurality of waterproof louver blades that are approximately inclined "S" in parallel and closely combined to form a labyrinth. Sheet metal structure, waterproof louver 1 and waterproof louver structure mounting part 3 are connected by welding to realize the connection between each waterproof louver, waterproof louver and ventilation mesh are connected by countersunk head screws, and the assembled waterproof device is connected to the cabinet through screws The front door liner is installed, as shown in Figure 2 after completion, the waterproof device is installed inside the cabinet, not protruding outside the cabinet, and the ventilation mesh is between the waterproof louvers and the heat exchanger inside the cabinet, and is not exposed outside the cabinet .

As shown in Figure 3, the dotted arrow shows the direction of the limit spray water, and the waterproof louver 1 can ensure that the water sprayed from all directions at the outer circulation air duct will not enter the inside of the cabinet. Through the reflection of water spray, the waterproof louver 1 can be well completed. Waterproof function, and its ventilation area is large, and the ventilation effect is good.

Even under harsh conditions such as strong water jets, the waterproof louver 1 can quickly discharge a small amount of water droplets entering the module to the outside of the cabinet. There are two long drainage slits 13 on the 12, and the slope 11 is designed so that water droplets can quickly flow into the horizontal platform along the slope, and flow into the bottom drain hole through the long drainage slits 13 at the horizontal platform, thereby draining the cabinet; the design of the horizontal platform 12 not only ensures The accurate confluence of water droplets also realizes the planar contact between the waterproof device and the front door liner, ensuring reliable contact.

To sum up, the utility model can prevent jet water from entering the cabinet, and in harsh environments, the water droplets entering the module can be quickly discharged outside the cabinet, thereby ensuring the reliability of the outdoor cabinet, especially the forced air-cooled outdoor cabinet.
