Description

Technical Field

[0001] The utility model relates to the field of control cabinets, in particular to a control cabinet with good moisture-proof performance. Background Art

[0002] The control cabinet is a protective cabinet used to install control devices of mechanical equipment. At present, the control cabinet has a simple structure and is mostly a metal box. There are still certain problems in its use. For example, in order to ensure the heat dissipation effect of the control devices installed inside the control cabinet, a cooling fan and a heat dissipation slot will be installed on the control cabinet. It lacks a drying structure. After the external air enters the control cabinet, the moisture in the air cannot be dried in advance, so that the moisture enters the control cabinet, which easily causes problems in the use of the control devices inside the control cabinet. At the same time, traditional control cabinets are mostly single-layer structures. During transportation or use, if there is an external force collision, it is easy to cause the control cabinet shell to deform, and the deformed part is easy to contact the control devices inside the control cabinet, causing damage to the control devices and poor safety performance. Utility Model Content

[0005] By adopting the above technical scheme, the utility model has a base connected to the bottom of the cabinet, and a frame is installed in the drying chamber inside the base, and cooperates with the lime particles and moisture-absorbing cotton inside the frame. When the exhaust fan is working, a negative pressure is generated at the air guide groove, and the air is drawn into the cabinet through the air inlet chamber. During the period, the air is dried through the double moisture absorption of the lime particles and the moisture-absorbing cotton, thereby preventing moisture from entering the cabinet. The control components installed inside the control cabinet are protected. The cabinet is composed of an outer layer and an inner layer, and a reinforcing bracket is installed between the outer layer and the inner layer, so that a buffering cavity is formed between the outer layer and the inner layer. When the outer layer is impacted and deformed, it will not affect the structure of the inner layer, thereby preventing the control components from being bumped due to deformation, thereby improving safety.

[0006] The utility model is further configured as follows: an air guide groove connected to the cabinet is opened on the top of the base, the air guide groove is connected to the drying chamber, and a first dustproof net is installed inside the air guide groove.

[0007] The above technical solution facilitates the air in the drying chamber to enter the cabinet.

[0008] The utility model is further configured as follows: an air inlet cavity is provided on the base, and the air inlet cavity is connected with the drying cavity through a slot.

[0009] The above technical solution facilitates the entry of external air into the drying chamber.

[0011] The frame is fixed in a limited position by adopting the above technical solution.

[0012] The utility model is further configured as follows: the top of the cabinet is connected with a sleeve, and an exhaust fan is arranged inside the sleeve.

[0013] The above technical solution is adopted to facilitate the generation of suction force inside the cabinet.

[0014] The utility model is further configured as follows: a limiting block bolted to the sleeve is symmetrically bolted to the surface of the exhaust fan.

[0015] The above technical solution is adopted to limit the position of the exhaust fan.

[0016] The utility model is further configured as follows: a mounting plate is installed inside the cabinet through a fixing piece, and the mounting plate is used in conjunction with the control device.

[0017] The above technical solution is adopted to facilitate the installation of control devices.

[0018] The utility model is further configured as follows: a second dustproof net is installed inside the sleeve.

[0019] The above technical solution is adopted to prevent dust from entering the cabinet.

[0020] In summary, the utility model has the following beneficial effects:

[0021] 1. The utility model has a base connected to the bottom of the cabinet, a frame is installed in the drying chamber inside the base, and lime particles and moisture-absorbing cotton inside the frame are matched. When the exhaust fan is working, negative pressure is generated at the air guide groove, and air is drawn into the cabinet through the air inlet cavity. During the period, the air is dried through the double moisture absorption of the lime particles and the moisture-absorbing cotton, so as to prevent moisture from entering the cabinet together, and protect the control components installed inside the control cabinet;
