[0002] The distribution box can be installed with electric meters, controllers, switches and other components, and the components can be protected. It is widely used. Some distribution boxes need to be placed outdoors. In order to ventilate and dissipate heat for the distribution box, the side of the distribution box is usually provided with heat dissipation holes. A baffle is provided on the top of each heat dissipation hole, and the baffle opening faces downward. The heat dissipation holes of the distribution box used outdoors are prone to water ingress, especially on rainy days. It is impossible to ensure that the water sprayed from the lower side of the baffle will not enter the box. Summary of the invention

The cover plate is connected from top to bottom. By using the "chimney" principle, the internal hot air discharged from the heat dissipation hole can quickly rise through the cover plate to achieve a good heat dissipation effect. On rainy days, under the action of the top plate blocking and the baffle I blocking, rainwater flows downward along the top plate and the outer edge of the baffle I, and it is not easy for water to enter the heat dissipation hole; in addition, a number of cover plate heat dissipation holes are arranged on the side of the cover plate, and the baffle II opens upward. Since the baffle II and the baffle I are arranged in a staggered manner, and the baffle II is arranged on the baffle I, first, the heat dissipation effect is increased, and second, on rainy days, rainwater flows downward along the baffle II, and under the blocking of the baffle I, the rainwater is not easy to enter the shell.

DETAILED DESCRIPTION

[0014] As shown in the figure, the utility model is an external waterproof cover plate of a distribution box shell, including a distribution box shell, a plurality of side wall heat dissipation holes 3 are arranged on the side wall 1 of the distribution box shell, and a baffle 12 is arranged on the outer top of each heat dissipation hole. The baffle 1 is arc-shaped (or inclined) and has an opening facing downward. The lower edge of the baffle 1 is lower than the lower edge of the heat dissipation hole. The purpose is that when it rains, rainwater flows downward along the baffle 1 and is not easy to enter the box body from the heat dissipation hole of the shell. Example

[0015] On the outside of the baffle I, a cover plate 4 is installed on the shell of the distribution box. The cover plate is connected to the outside world from top to bottom to form a "chimney". The cover plate is composed of a front plate 4-1, two side plates 4-2, a top plate 4-3 and a bottom plate (opposite to the top plate and with the same length as the top plate). Side plates are installed on both sides of the front plate, each of which has an L-shaped cross-section. The top plate and the bottom plate are installed on the top and bottom of the front plate, respectively, and the width of the top plate and the bottom plate is smaller than the width of the long side of the side plate. The short side of the side plate is installed on the side wall of the shell of the distribution box. This structure, on the one hand, utilizes the "chimney" principle, and the heat dissipation holes discharge the internal hot air, which can rise rapidly through the cover plate; on the other hand, on rainy days, under the action of the cover plate, rainwater is not easy to enter the shell, which effectively prevents rainwater from splashing in. Example

[0016] A number of cover plate heat dissipation holes 6 are provided on the front plate, and a baffle II5 is provided on the outer bottom of each cover plate heat dissipation hole. The baffle II is arc-shaped or inclined, and the opening faces upward. The number of cover plate heat dissipation holes can be the same as the number of heat dissipation holes in the distribution box shell. Adding heat dissipation holes on the outer side of the cover plate can increase heat dissipation. During installation, baffle II and baffle I are arranged alternately, and the lower edge of baffle II is arranged above the upper edge of baffle I. On rainy days, rainwater flows downward from the top of the cover plate and the heat dissipation holes of the cover plate respectively. Rainwater entering from the top plate of the cover plate will flow downward along the outer edge of baffle I; rainwater entering from the heat dissipation holes of the cover plate will flow downward along baffle II, which effectively prevents rainwater from splashing into the shell.

[0017] The utility model is an external waterproof cover plate for the shell of the distribution box. The cover plate is installed on the outer side of the shell of the distribution box. The cover plate is connected from top to bottom. By using the "chimney" principle, the internal hot air discharged from the heat dissipation hole can rise rapidly through the cover plate to achieve a good heat dissipation effect. On rainy days, under the blocking of the top plate and the baffle I, rainwater flows downward along the outer edge of the top plate and the baffle I, and it is not easy for water to splash into the heat dissipation hole of the shell; in addition, a plurality of cover plate heat dissipation holes are arranged on the side of the cover plate, and the baffle II opens upward. Since the baffle II and the baffle I are arranged in an interlaced manner, and the baffle II is arranged on the baffle I, first, the heat dissipation effect is increased, and second, on rainy days, rainwater flows downward along the baffle II, and under the blocking of the top plate and the baffle I, rainwater is not easy to enter the shell. The utility model prevents rainwater from splashing into the shell of the distribution box, effectively ensuring heat dissipation and waterproofing. It meets the IP44 protection level requirements of the shell of the distribution box.

The protection scope of this application shall be based on the content of the claims, and any equivalent transformation based on the technical enlightenment of this application is also within the protection scope of this application.
