Description

Technical Field

[0001] The invention relates to the technical field of power distribution cabinets with protection functions, and in particular to a power distribution cabinet with protection functions. Background Art

[0002] The existing power distribution cabinet with safety protection function often has many problems during use. During use, the internal components connected with different voltages cannot be installed in a classified manner. The strong current components are prone to generate large arcs when the power is turned on. The safety performance is poor and the use effect is poor.

[0003] The patent announcement number CN220086701U is a power distribution cabinet with a protective function. The power distribution cabinet includes a base, a protective shell is provided at the upper end of the base, a rectangular cavity is provided in the protective shell, a control panel is provided on the front side of the protective shell, a plurality of controllers are provided on the control panel, a plurality of filters are provided on the left and right outer walls of the protective shell, the plurality of filters are connected to the interior of the rectangular cavity, and a cleaning mechanism and a heat dissipation mechanism are provided in the rectangular cavity. The patent drives the right reciprocating screw to rotate after the motor is energized, and the two reciprocating screws rotate synchronously through the transmission assembly, so that the two sliders drive the corresponding brush layers to move up and down, sweeping the dust on the filter net, ensuring the air permeability of the filter net, thereby avoiding the risk of the electrical components in the power distribution cabinet being damaged due to excessive temperature due to clogging of the filter net due to dust accumulation.

[0004] The above patent uses a transmission component to make the two reciprocating screws rotate synchronously, so that the two sliders drive the corresponding brush layers to move up and down, sweeping the dust on the filter screen to ensure the air permeability of the filter screen, thereby avoiding the filter screen being blocked by dust accumulation and the risk of electrical components in the distribution cabinet being damaged due to overheating. However, a long power cord may cause people to trip or collide, resulting in safety accidents. A long power cord is susceptible to squeezing or friction from external objects, which may cause damage to the insulation layer and increase the risk of electric shock. A power cord that is too long will cause more heat to be generated, thereby reducing overall energy efficiency. Summary of the invention

[0014] The present invention provides a power distribution cabinet with a protective function.

The movement of the cross bar will push the No. 1 fixed rod to move. The movement of the No. 1 fixed rod will slide on the inner wall of the No. 1 fixed groove. The sliding of the No. 1 fixed rod on the inner wall of the No. 1 fixed groove will push the No. 2 fixed rod to slide. The rotation of the reel will drive the power cord to be wound. When the reel rotates to the moving extent, the No. 1 fixed block will contact the No. 2 fixed block to limit the reel. The reel drives the power cord to be wound to prevent the long power cord from being squeezed or rubbed by external objects, which may cause the insulation layer to be damaged and increase the risk of electric shock. An excessively long power cord will cause voltage drop, especially under high current load, which may affect the normal operation and performance of the equipment.

[0015] (2) According to the invention, when the power distribution cabinet is hit, the outer shell will slide on the base, and the sliding of the outer shell will drive the partition to move, and the movement of the partition will drive the sliding block to slide, and the sliding block will squeeze the elastic telescopic rod to shrink and absorb the impact force of the outer shell. The movement of the outer shell will drive the movement of the outer support column, and the movement of the outer support column will drive the movement of the inner support rod, and the movement of the outer support column will push the sliding rod to slide, so as to avoid the center of gravity shifting when the outer shell moves, causing the power distribution cabinet to tip over. At the same time, the shift of the center of gravity may cause uneven force on the electrical components inside the power distribution cabinet, thereby affecting its performance or causing failure.

[0016] (3) According to the invention, after the power distribution cabinet is placed in the corresponding position, the reel reels up the power cord and then closes the cabinet door. The rotation of the cabinet door will drive the fixed pin to move, and the movement of the fixed pin will contact the fixed claw. The movement of the fixed pin and the contact with the fixed claw will push the fixed claw to rotate. The rotation of the fixed claw will move along the surface of the fixed pin. When the outer shell is hit, the cabinet door is fixed to prevent the electrical equipment inside from being exposed after the cabinet door is knocked open. The operator may accidentally contact the live parts, increasing the risk of electric shock. It may also cause the door panel or other components to fall and cause personal injury, especially when the cabinet is heavy or the structure is complex. BRIEF DESCRIPTION OF THE DRAWINGS
