Description

An outdoor rainproof electrical cabinet

technical field

The invention belongs to the field of electrical equipment, and in particular relates to an outdoor rainproof electrical cabinet.

Background technique

During the use of electrical cabinets, many electrical cabinets are used outdoors and are often exposed to rain, causing internal water to burn out, and at the same time, there is a lot of water vapor in relatively humid places, which leads to electrical leakage risks inside the electrical cabinet. The invention can effectively Prevent water from entering the electrical cabinet and eliminate internal moisture.

Contents of the invention

The invention aims at the disadvantage that the existing outdoor electric cabinet is easy to enter rainwater, and provides an outdoor rainproof electric cabinet, which solves the series problems that the electric cabinet is easy to enter rainwater.

In order to achieve the above-mentioned technical purpose and achieve the above-mentioned technical effect, the present invention is realized through the following technical solutions:

An outdoor rainproof electrical cabinet, including a cabinet body, a cabinet door and a cabinet top, the cabinet body is an L-shaped clamping structure at the closing position of the cabinet door, and the L-shaped clamping structure includes a protrusion disposed on the cabinet body The outer L block and the inner L block protruding from the cabinet door, the inner surface of the outer L block is engaged with the outer surface of the inner L block, and the clamping part of the outer L block and the inner L block is provided There is a sealing ring, and the cross-section of the cabinet top is trapezoidal, and a water-guiding protrusion is arranged on the trapezoidal waistline located on one side of the cabinet door.

Further, the water guide protrusion is an open pipe, and the opening direction of the pipe faces the direction of the top of the cabinet, and is used for circulating the water flowing down from the top of the cabinet.

Further, the water guide protrusion is connected to the cabinet top by welding.

Further, the two ends of the water guiding protrusions extend outward from the trapezoidal waistline of the top of the cabinet.

Further, horizontal and vertical flow slots are provided at the bottom of the cabinet, and legs higher than the bottom of the cabinet are provided on the side of the flow slot.

Further, heat dissipation grooves are provided on the side and/or back of the cabinet body, and the notch direction of the heat dissipation grooves faces the bottom end of the cabinet body.

The beneficial effects of the present invention are:

Adopting the technical scheme of the invention, the invention can effectively prevent water from entering the electrical cabinet and eliminate internal water vapor, and has simple structure and low cost.

detailed description

The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments.

Referring to Figures 1 to 3, it includes a cabinet body 1, a cabinet door 2 and a cabinet top 3, the cabinet body 1 is an L-shaped clamping structure at the closing position with the cabinet door 2, and the L-shaped clamping structure includes a convex The outer L block 11 arranged on the cabinet body 1 and the inner L block 21 protrudingly arranged on the cabinet door 2, the inner side of the outer L block 11 is engaged with the outer side of the inner L block 21, and the A sealing ring 4 is provided at the joint between the outer L block 11 and the inner L block 21. Most of the water will be blocked by the L-shaped curve and flow away. The sealing ring 4 is further sealed to prevent water from entering. The cross-section is trapezoidal and is provided with water-guiding protrusions 5 on the trapezoidal waistline located on one side of the cabinet door 2 .

The water guide protrusion 5 is an open pipe, and the opening direction of the pipe faces the direction of the top 3 of the cabinet, and is used for circulating the water flowing down from the direction of the top 3 of the cabinet.

The water guide protrusion 5 is connected to the cabinet top 3 by welding.

The two ends of the water guide protrusion 5 extend outwards from the trapezoidal waistline of the cabinet top 3 .

The bottom of the cabinet body 1 is provided with horizontal and vertical flow slots 6 , and the sides of the flow slots 6 are provided with feet 8 higher than the bottom end of the cabinet body 1 .

A cooling groove 7 is provided on the side and/or back of the cabinet body 1 , and the notch direction of the cooling groove 7 faces the bottom end of the cabinet body 1 .

Action process and principle of the present invention

When it rains, since the cabinet door 2 is closed, the cabinet body 1 has an L-shaped structure at the close of the cabinet door 2. Because it is tightly pressed with the sealing ring 4, the rainwater cannot penetrate and the blocked rainwater follows the slideway formed by the L-shaped mechanism. The heat generated by the use of electrical appliances inside will evaporate the internal water vapor from the heat sink 7, and the water at the top on the side of the cabinet door 2 will enter the water guide protrusion 5 and be discharged from it, while the water at the bottom will The outflow is guided by the flow slot 6 . .

The above descriptions are only preferred embodiments of the present invention, and are not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and changes. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention shall be included within the protection scope of the present invention.
