Description

Technical Field

[0001] The utility model relates to the field of shielding cabinets, in particular to an active heat dissipation shielding cabinet based on dynamic temperature and humidity collection. Background Art

[0002] Shielded cabinets are used in dynamic temperature and humidity acquisition systems. Shielded cabinets are a type of cabinet, also called electromagnetic shielding cabinets. Shielded cabinets can be used to place computers, which can prevent electromagnetic waves from causing personal injury, effectively suppress computer electromagnetic information leakage, and prevent external strong electromagnetic interference from affecting the normal operation of the computer. Heat is generated inside the shielded cabinet when it is working, and this heat needs to be dissipated in time to ensure the normal operation of the shielded cabinet. Some shielded cabinets are installed in the open air, which makes the bottom of the cabinet easy to get in and get damaged. Existing shielded cabinets usually do not have waterproof functions. The Chinese utility model patent with application number 202410039868.6 discloses an active external circulation ventilation shielded cabinet, which solves the problem that the existing electromagnetic shielding cabinets have general heat dissipation performance and generally do not have the function of flooding prevention. When electromagnetic shielding cabinets are used in some low-lying areas, when flooding and waterlogging occur, the electromagnetic shielding cabinet will be threatened by flooding and water ingress, causing damage to internal equipment and causing losses.

[0003] The above-mentioned active external circulation ventilation shielded cabinet can play the role of active circulation and flood prevention. However, in actual use, it was found that it has defects: 1. The cabinet is raised by a lifting mechanism, and the structure is relatively complex, which is not conducive to reducing production costs; 2. The cabinet is ventilated and heats up by setting through holes at the upper and lower positions, and water easily enters the through holes on the lower side. Summary of the invention

[0004] In view of the shortcomings of the prior art, the utility model provides an active heat dissipation shielded cabinet based on dynamic temperature and humidity collection, which can solve the problem that the lifting mechanism structure is relatively complex and not conducive to reducing production costs, and the upper and lower through holes are used for ventilation and heat dissipation, and the lower through holes are prone to water accumulation.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an active heat dissipation shielding cabinet based on dynamic temperature and humidity collection, comprising a cabinet, a cabinet door sealed with the cabinet body is provided on the front side of the cabinet, through holes are respectively provided on the upper ends of the left and right sides of the cabinet, exhaust fans and hair dryers are respectively installed at the through holes, and a first electromagnetic shielding net is also installed on the outside of the through holes;

[0006] A plurality of air holes are embedded in the bottom plate of the cabinet, and the air holes are distributed in a rectangular array as a whole, and a second electromagnetic shielding net is fixedly arranged on the floor inside the cabinet above the air holes;

[0007] The four corners of the bottom surface of the cabinet are respectively fixed with vertical support rods, the bottom surfaces of the support rods are respectively fixed with universal wheels with a limiting function, and the support rods are slidably provided with a floating sealing structure that matches the bottom surface of the cabinet.

[0008] As a preferred technical solution, a rectangular through hole matching the cabinet door is embedded in the cabinet, a rectangular frame is fixed at the rectangular through hole, and a first sealing gasket matching the cabinet door is bonded to the rectangular frame.

[0009] As a preferred technical solution, the floating sealing structure includes a flat plate, which is a rectangular structure as a whole, with four corners embedded with sockets that are slidably sealed with the support rods, and a second sealing gasket that is bonded to the edge of the upper surface of the flat plate and is sealed with the bottom surface of the cabinet;

[0010] Floating blocks are respectively arranged on the outer sides of the four sides of the flat plate, and the floating blocks are respectively fixedly connected to the side surfaces of the flat plate through support rods.

[0011] As a preferred technical solution, the floating block is a foam block or a hollow sphere.

[0012] As a preferred technical solution, the vertical projection areas of the flat panel and the cabinet are the same.

[0013] As a preferred technical solution, magnetic blocks that attract and cooperate with the bottom surface of the cabinet are respectively embedded on the inner sides of the four sides of the flat plate.

When in use, the through holes are all located at a high position of the cabinet, thereby avoiding the problem of water easily entering the through holes at a low position, and the first electromagnetic shielding net can play an electromagnetic shielding role.

[0016] 2. The utility model has a plurality of air holes embedded in the bottom plate of the cabinet, and the air holes are distributed in a rectangular array as a whole.

[0017] 3. The utility model is provided with universal wheels with a limiting function fixedly on the bottom surfaces of the support rods, and a floating sealing structure cooperating with the bottom surface of the cabinet can be slidably provided on the support rods.
