Description

Technical Field

[0001] The utility model belongs to the technical field of power distribution equipment, in particular to a power distribution box. Background Art

[0002] The distribution box is a low-voltage distribution device that assembles switchgear, measuring instruments, protective electrical appliances and auxiliary equipment in a closed or semi-closed metal cabinet or on a screen according to the requirements of electrical wiring. It is a widely used distribution device. It mainly installs components in the circuit and monitors and controls the circuit by connecting to the circuit. Since the traditional electrical component structure is mostly fixed in the distribution box and cannot be adjusted according to electrical components of different types and sizes, the internal space utilization rate of the distribution box is not high, and when the electrical components are damaged, it is inconvenient to repair one of the components, which increases the difficulty of maintenance. Although there are some distribution boxes that can adjust the height, they are all adjusted by snap-in or sleeve-type, so there will be certain distance restrictions when adjusting.

[0003] The Chinese utility model patent with publication number CN219535321 U discloses a distribution box with an adjustable internal bracket. An adjustment mechanism is designed on the side of the distribution box body, and then after placing a sliding plate inside a limit frame and adjusting the height of the sliding plate, the threaded block can be moved closer to the limit frame by rotating the gear, so that the side of the distribution box body can be clamped by the clamping action of the limit frame and the rubber plate. Therefore, the adjustment mechanism can be fixed, which is convenient for supporting the sliding plate. At the same time, the adjustment mechanism can also adjust the height at any time, and when fixing the adjustment mechanism, the limit annular groove opened by the extrusion plate can limit the steel ball, thereby reducing the friction between the chain and the extrusion plate. However, the device still has other problems. The device does not solve the problem of heat dissipation at an appropriate temperature. Utility Model Content

[0004] The purpose of the utility model is to provide a distribution box to solve the problems raised in the above background technology.

[0005] In order to achieve the above purpose, the following technical solution is provided: a distribution box, comprising:

[0006] Distribution box body;

[0007] A heat dissipation mechanism is arranged inside the distribution box body;

[0008] A through hole is provided on the top plate of the distribution box body;

[0009] A detection mechanism is arranged above the distribution box body;

[0010] Wherein, the detection mechanism includes:

[0011] Testing box;

[0012] The airbag is arranged inside the detection box and connected to the distribution box body;

[0013] The micro contact switch is arranged inside the detection box.

[0014] In the above technical solution, further, the bottom plate of the distribution box body is provided with ventilation holes.

[0015] In any of the above technical solutions, further, a support is installed at the bottom of the distribution box body, a baffle is arranged between the support and the vent, and a gap is arranged between the baffle and the bottom plate of the distribution box body.

[0016] In any of the above technical solutions, further, a through hole is provided on the top plate of the distribution box body, the detection box is mounted on the top plate, and the through hole is provided inside the detection box to discharge the hot air generated inside the distribution box body into the detection box.

[0017] In any of the above technical solutions, further, the heat dissipation mechanism includes:

[0018] The motor is fixedly mounted on the top plate inside the distribution box body;

[0019] The fan is arranged on the motor via a rotating shaft.

[0020] In any of the above technical solutions, further, the motor is electrically connected to the micro contact switch.

[0021] In any of the above technical solutions, further, a slot is provided on the side of the distribution box body, and a dustproof net can be installed through the slot.

[0022] In any of the above technical solutions, further, the covering layer of the airbag is made of a heat-sensitive material.

[0023] The beneficial effects of the utility model are:

[0024] 1. A detection box is installed above the distribution box body, and an airbag is fixedly placed inside the detection box. A through hole is opened between the detection box and the distribution box body. The hot air generated when the distribution box body is working can enter the detection box through the through hole. When the temperature inside the detection box becomes higher, the volume of the air in the airbag will expand, thereby increasing the volume of the airbag. The edge of the airbag can touch the micro-contact switch, thereby causing the motor to rotate and drive the fan to reduce the temperature inside the distribution box body.

[0025] 2. By setting a vent at the bottom of the distribution box body, the heat inside the distribution box body can be dissipated. At the same time, a moisture-proof plate is set on the support of the distribution box body to prevent moisture from evaporating into the distribution box body and damaging electrical components when it rains or there is water on the ground.

[0026] 3. By opening a slot at the bottom of the distribution box body, the dust net can be directly inserted or pulled out through the slot to prevent dust from entering, effectively reducing dust clogging electrical components while increasing ventilation effects.
