Description

Technical Field

[0001] The utility model relates to the technical field of power distribution cabinets, in particular to a power distribution cabinet with a temperature regulating function. Background Art

[0002] The distribution cabinet (box) is divided into power distribution cabinet (box), lighting distribution cabinet (box), and metering cabinet (box). It is the final equipment of the power distribution system. The distribution cabinet is a general term for the motor control center. The distribution cabinet is used in places where the load is relatively dispersed and there are fewer circuits; the motor control center is used in places where the load is concentrated and there are more circuits. They distribute the power of a circuit of the upper-level distribution equipment to the nearest load. This level of equipment should provide protection, monitoring and control for the load.

[0003] The patent document with the announcement number CN210142853U that has been published discloses a power distribution cabinet with heat dissipation, and its technical solution is as follows: the cabinet is fixedly connected to the top of the base, and a vertical partition is fixedly connected to the rear side of the cabinet, and a through hole is set on the surface of the vertical partition, and support plates are fixedly connected to both sides of the cabinet, and ribs are fixedly connected to the bottom of the support plate, and grooves are set at both ends of the top of the support plate, and layer plates are slidably connected inside the grooves. By setting layer plates inside the cabinet, when electrical components of different sizes need to be placed, the positions of each layer plate can be adjusted first, because a cooling fan is fixedly connected to the rear side of each layer plate, and the electrical components of each layer can be cooled, which is conducive to increasing the circulation of air inside the cabinet, thereby improving the heat dissipation efficiency and ensuring that the electrical components inside the cabinet will not be damaged due to high temperature.

[0004] The distribution cabinet in the prior art usually uses a cooling fan to effectively dissipate heat, so as to achieve the purpose of regulating the temperature of the distribution cabinet. However, the cooling fan is usually fixedly installed in a fixed position, and the heat dissipation range is limited. Therefore, cooling fans need to be installed in different positions. When there are more cooling fans, a large amount of heat will also be generated, and the cost of use will increase. Therefore, a distribution cabinet with a temperature regulation function is needed.

[0018] Optionally, there are two cooling fans in total, and the two cooling fans are symmetrically arranged on the left and right.

[0019] By adopting the above technical solution, the heat dissipation efficiency is further improved.

[0020] Optionally, a guide rod is provided on the sliding block, the guide rod is located on one side of the screw rod, and the guide rod is fixedly connected to the inner top of the power distribution cabinet.

[0021] By adopting the above technical solution, the guide rod can make the slider slide stably on the screw rod.

[0022] Optionally, the bottom end of the screw rod is fixedly connected to a limiting block.

[0023] By adopting the above technical solution, it is possible to prevent the slider from falling off the screw rod.

[0024] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0025] The technical solution of the present application can drive the screw rod to rotate through the output shaft of the motor. When the screw rod rotates, the rotational motion of the slider can be converted into linear motion, thereby driving the cooling fan to perform reciprocating lifting and lowering motion, which can improve the heat dissipation range and heat dissipation effect of the electronic components inside the distribution cabinet. The partition can separate the cooling fan from the electronic components, so that the cooling fan will not collide with the electronic components when it is lifted and lowered, which is convenient and practical.
