Abstract
Description
Technical Field
[0001] The utility model relates to the field of electrical equipment, in particular to an outdoor power distribution box with automatic heat dissipation. Background Art
[0002] The components inside the distribution box will emit heat during operation, so the inside of the distribution box needs to be cooled. Outdoor distribution boxes are more likely to generate high temperatures in the summer, resulting in untimely heat dissipation, which results in poor heat dissipation. In addition, the heat dissipation holes of the outdoor distribution box should not be too large to avoid failing to protect the isolation components. At the same time, safety and protection need to be considered, and isolation baffles are required. However, the existing isolation baffles further compress the heat dissipation space of the circuits and components inside the switchgear. Utility Model Content
[0003] Based on the above problems, the utility model aims to provide an outdoor distribution box with automatic heat dissipation.
[0004] In response to the above problems, the following technical solutions are provided: an outdoor distribution box with automatic heat dissipation, comprising a box body, a mounting frame and a protective frame are arranged inside the box body, a cooling fan is arranged below the mounting frame, a protective device is arranged above the protective frame, the protective device comprises a shell, an insulating member which is retractable and retractable and arranged inside the shell body, and a winding mechanism for winding up the insulating member, the winding mechanism comprises a motor and a drive shaft, one end of the insulating member is wound around the drive shaft, and the other end is arranged outside the shell, sliding grooves for vertical sliding of the insulating member are arranged on both sides of the protective frame, the protective frame and the insulating member divide the box body into an inner cavity and an outer cavity, a temperature sensing mechanism for sensing temperature is arranged on one side of the protective frame corresponding to the inner cavity, the temperature sensing mechanism is electrically connected to the motor, and a button for controlling the winding mechanism is arranged on the other side of the protective frame opposite to the outer cavity.
[0005] By adopting the above technical solution, a retractable and retractable insulating member is used to play a safety protection role, and the inner cavity is shielded to prevent dust, rainwater, etc. from entering. It has higher protection performance and is more suitable for outdoor use. At the same time, a temperature sensing mechanism is provided. When the temperature of the inner cavity is too high, the motor controls the drive shaft to rotate and retract the insulating member, so that the inner cavity and the outer cavity are connected, the heat dissipation space is expanded, the heat dissipation fan works, and the heat dissipation efficiency is improved. A sliding groove is provided to make the lowering and retracting of the insulating member more stable. A button is provided. When maintenance and installation are required, the drive shaft can also be controlled by the button to rotate and retract the insulating member.
[0006] The utility model is further configured as follows: the protective frame includes two side frames, and a plurality of L-shaped heat dissipation holes are longitudinally arranged on the side frames, one end of the L-shaped heat dissipation hole opens toward the side of the box body, and the other end opens toward the inner cavity, the opening toward the inner cavity is higher than the opening toward the side of the box body, and a plurality of heat dissipation ports corresponding to the L-shaped heat dissipation holes are arranged at positions corresponding to the side frames of the box body.
[0007] By adopting the above technical solution, the L-shaped heat dissipation hole facilitates airflow to dissipate heat through the heat dissipation port, while rainwater, dust, etc. entering the L-shaped heat dissipation hole are blocked by the corner and are not easy to enter the inner cavity, thereby further improving the protection performance. At the same time, the opening toward the inner cavity is higher than the opening toward the side of the box body, that is, the section of the L-shaped heat dissipation hole toward the inner cavity is inclined, thereby further preventing rainwater from entering the inner cavity, and the rainwater will flow out from the heat dissipation port again along the original path.
[0008] The utility model is further configured as follows: the L-shaped heat dissipation hole is connected to the sliding groove, and a discharge outlet is provided at the lower end of one side of the sliding groove corresponding to the outer cavity.
[0009] By adopting the above technical solution, the heat dissipation hole is transformed from L-shape to inverted T-shape. When the insulating part is rolled up, the heat dissipation hole is connected with the sliding groove to improve the heat dissipation efficiency. When rainwater enters the sliding groove from the heat dissipation hole, a discharge outlet is set at the lower end of the sliding groove to prevent rainwater from entering the inner cavity.
[0010] The utility model is further configured as follows: a ventilation channel connected to the outer cavity is arranged on the other side of the side frame relative to the sliding groove, and a protective baffle for preventing water and dust from entering the inner cavity is arranged on one side of the ventilation channel corresponding to the inner cavity.
[0011] By adopting the above technical solution, compared with the L-shaped heat dissipation hole opening being fitted with the heat dissipation port, a ventilation channel is set to increase gas flowability and improve heat dissipation efficiency. At the same time, dust, water, etc. will not directly enter the L-shaped heat dissipation hole, but fall into the ventilation channel, which is convenient for cleaning. The protective baffle further improves the protection performance.
[0012] The utility model is further arranged that: the air permeable channel is arranged on the hinged side of the box body and the protective door and is communicated with the external cavity.
[0013] By adopting the above technical solution, when the protective door is opened or closed, the direction in which air enters the box is arranged opposite to the air permeable channel, so that the gas fluidity is better and the heat dissipation performance is better.
