Description

Technical Field

[0001] The utility model belongs to the field of control cabinets, and in particular relates to a novel outdoor control cabinet structure used in extreme environments. Background Art

[0002] The control cabinet is assembled according to the GIS product grade, with components, electrical parts, measuring instruments, protection devices and auxiliary equipment for GIS operation. Due to the increasing demand for State Grid GIS products in recent years and the wider areas, the requirements for outdoor installed GIS control cabinets have also increased accordingly.

[0003] When GIS products are operated in areas with strong winds and sand, heavy rainfall in summer, or complex and changeable environments, the sealing effect of the existing control cabinet structure is not ideal, and the control cabinet is easily entered by rainwater and wind and sand, which can easily cause damage to the components in the control cabinet, thereby affecting the normal operation of the GIS product. In view of this, it is extremely necessary to design a new type of waterproof, sand-proof, and sealed outdoor control cabinet structure. Utility Model Content

[0004] In view of this, the utility model aims to propose a novel outdoor control cabinet structure for use in extreme environments, in order to solve at least one of the above-mentioned technical problems.

[0005] In order to achieve the above object, the technical solution of the utility model is implemented as follows:

[0006] A novel outdoor control cabinet structure for use in extreme environments comprises a rain cover, the lower end of the rain cover is connected to a control cabinet body, a front door and a rear door are respectively installed on the front and rear sides of the control cabinet body, a dust cover is installed on the rear door, and a base frame is installed at the bottom of the control cabinet body;

[0007] The frames of the front door and the rear door are both provided with inner and outer flanges, the inner and outer flanges are both connected with a sealing strip 1, and the outer side of the sealing strip 1 is connected with a sealing strip 2;

[0008] An inner sealing plate is installed on the inner side of the control cabinet body, and thermal insulation cotton is filled between the inner sealing plate and the outer wall of the control cabinet body.

[0009] Furthermore, a card slot is provided on one side door of the front door and the rear door, a sealing gasket is connected to the inner side of the card slot, a baffle is slidably connected to the other side door of the front door and the rear door, a through slot is provided on the outer side of the baffle, a tooth block is connected to the inner side of the through slot, a gear is meshed on the tooth block, a rotating rod is connected to the inner key of the gear, and the rotating rod is rotatably connected to the front door and the rear door respectively.

[0010] Furthermore, the control cabinet body is a double-layer structure, the outer wall of the control cabinet body is 2 mm thick, and the inner sealing plate inside the control cabinet body is 1.5 mm.

[0011] Furthermore, the sealing strip 1 and the sealing strip 2 are both distributed in an "Ω" shape, and the sealing strip 1 and the sealing strip 2 are distributed overlapping each other.

[0012] Furthermore, the thermal insulation cotton is evenly distributed between the control cabinet body and the inner sealing plate, and the thermal insulation cotton is 20 mm thick.

[0013] Furthermore, the sealing gasket is a side "U"-shaped structure, and the end of the sealing gasket is an inclined structure.

[0014] Furthermore, the tooth blocks are distributed at equal intervals at the connection between the through slot and the gear, and the through slot passes through one side surface of the baffle.

[0015] Compared with the prior art, the novel outdoor control cabinet structure for use in extreme environments described in the utility model has the following beneficial effects:

[0016] This new type of outdoor control cabinet structure used in extreme environments has inner and outer flanges added to the cabinet structure frame and adopts double-channel Ω-shaped sealing strips. When the cabinet door is closed, the two Ω-shaped sealing strips provide a double sealing effect. The first layer of sealing prevents fine sand from entering, and the second layer of sealing prevents rainwater from entering, so that the components in the cabinet are not eroded by wind, sand and rain, ensuring the working condition of the control cabinet and increasing the product life.

[0017] This new type of outdoor control cabinet structure used in extreme environments has a double-layer structure, with a 2.0mm thick stainless steel outer skin and a 1.5mm thick stainless steel inner cover. The left and right sides, top, front and back doors of the cabinet are each covered with 20mm thick insulation cotton. There is a rain cover on the top, the bottom of the cabinet is sealed, and the rear door can be equipped with an air conditioner. It is also equipped with a detachable air conditioner dust cover and is treated to prevent fine sand. It can keep warm and insulate, can cope with strong outdoor sunlight, and can cope with low temperatures. The installation of air conditioners can cool and dissipate heat, so that the components in the cabinet are in a constant temperature working environment, further improving their service life.

[0018] This new type of outdoor control cabinet structure used in extreme environments controls the rotating rod to drive the gear to rotate, thereby cooperating with the use of meshing gear blocks to smoothly drive the baffle to move, so that the baffle is stuck in the slot, and uses sealing gaskets to increase its sealing performance, strengthen the shielding and sealing of the gaps at the front and rear double doors, and further improve the rain and sand resistance.
