Description

Technical Field

[0001] The utility model relates to the field of distribution box accessories, in particular to a waterproof protective plate for a distribution box. Background Art

[0002] The distribution box is made of bent and assembled metal plates. The guard plates on both sides are important components of the distribution box. Generally, heat dissipation vents are opened on the surface of the guard plates on both sides of the distribution box to evacuate the heat generated by the internal distribution facilities. The distribution box used outdoors needs to consider the two functions of heat dissipation and water prevention. Therefore, linear heat dissipation vents are stamped on the surface of the guard plate, and a rain-proof slope is extended above the heat dissipation vents. Although this waterproofing can prevent rainwater from entering the box, the opening area of ​​the heat dissipation vents is limited, and the heat dissipation efficiency is lost.

[0018] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments.

[0019] like Figure 1 , Figure 2 As shown, the waterproof protective plate of the distribution box has a plate body 1 made of stainless steel or aluminum alloy, and a mounting hole is provided at the top corner of the plate body 1. The plate body 1 is sealed on both sides of the distribution box by screws, and a circle of rough lines 7 are provided on the inner side edge of the plate body 1. When the plate body 1 is connected to the main body of the distribution box, a sealing strip is provided at the rough lines 7, and the edges of the plate body 1 are sealed by squeezing the sealing strip through the rough lines 7;

[0020] like Figure 1 , Figure 3 As shown, the external plate 2 is also made of stainless steel or aluminum alloy material. The external plate 2 is placed on the outside of the plate body 1. The top of the external plate 2 is bent at a right angle to form a bent portion 21. The external plate 2 is fixedly connected to the plate body 1 through the bent portion 21. A sandwich space with open sides and a bottom is formed between the external plate 2 and the plate body 1. In order to improve the connection stability of the external plate 2, a plurality of grid plates 6 are fixed between the external plate 2 and the plate body 1 on both sides of the sandwich space. The grid plates 6 are arranged vertically to ensure a stable connection between the external plate 2 and the plate body 1.

[0021] like Figure 4As shown, an external heat dissipation outlet 3 is opened in the middle of the external plate 2, and the external heat dissipation outlet 3 is a plurality of vertically extending strip-shaped outlets. Two internal heat dissipation outlets 4 are opened at symmetrical positions on the surface of the plate body 1, and the internal heat dissipation outlets 4 are horizontally staggered with the external heat dissipation outlets 3;

[0022] The heat inside the distribution box enters the interlayer space along with the air through the inner heat dissipation vents 4, and the heat can be evacuated and discharged through the two sides, bottom and outer heat dissipation vents 3 of the interlayer space. The heat dissipation space is large and the air circulation is convenient. Since the inner heat dissipation vents 4 are blocked by the outer plate 2, rainwater cannot enter the distribution box through the inner heat dissipation vents 4. Some rainwater will also flow out from the bottom after entering the interlayer space through the outer heat dissipation vents 3 and cannot enter the distribution box. The entire protective plate has a good rainproof effect;

[0023] The two sides of the mezzanine space are connected to the external environment, so that the external wind can pass through the entire mezzanine space, further improving the heat dissipation effect. In order to prevent rainwater from entering from both sides of the mezzanine space, the outer end of the grid plate 6 is arranged to tilt downward to ensure that the airflow can pass through the mezzanine space while preventing rainwater from entering the mezzanine space.

[0024] like Figure 4 As shown, the middle part of the external plate 2 bulges outward, so that the sandwich space forms a state in which the middle part is thick and the two sides are thin. The external heat dissipation outlet 3 is located at the bulging part of the external plate 2, and a plurality of guide plates 5 are arranged at the position of the internal heat dissipation outlet 4, and the guide plates 5 are inclined toward the direction of the external heat dissipation outlet 3;

[0025] The middle size of the mezzanine space is large, which makes it easier for air to gather and be discharged toward the heat dissipation port 3. At the same time, the heat discharged from the distribution box is conducted toward the heat dissipation port 3 through the guide plate 5, so that the distance for concentrated heat evacuation is shortened, the evacuation efficiency is improved, and the heat is prevented from being mixed with the airflow in the mezzanine space, resulting in slower evacuation.

[0026] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
