Description

Technical Field

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

[0002] The distribution cabinet is divided into power distribution cabinet, lighting distribution cabinet and metering cabinet. It is the final equipment of the distribution system. The distribution cabinet is a general term for the motor control center. The distribution cabinet is suitable for occasions with relatively dispersed loads and fewer circuits; the motor control center is used in occasions with concentrated loads and more circuits. They distribute the electric energy 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. However, most distribution cabinets do not have the function of external impact protection. The distribution cabinet cannot be protected in the event of an external impact, which increases the difficulty of repairing the distribution cabinet.

[0003] Patent application number 202322568967.7 relates to the technical field of power distribution cabinets, and in particular to a power distribution cabinet with a protective function, including a power distribution cabinet and a cabinet door. A protective device is arranged on the outside of the power distribution cabinet, and the protective device includes a height adjustment unit, an anti-collision unit, a waterproof unit and an insect repellent unit. When there is water on the ground, the power distribution cabinet with a protective function can separate the bolt from the nut by rotating the nut, then pull out the bolt and lift the power distribution cabinet upward to a suitable height, and then pass the bolt through the positioning hole and connect it with the card hole and the nut, thereby completing the adjustment of the height of the power distribution cabinet to prevent water from seeping in. The interior of the distribution cabinet solves the problem raised in the background technology that if there is water on the ground during use, the height of the distribution cabinet cannot be adjusted, which will cause water to seep into the distribution cabinet and affect the normal use of the distribution cabinet. By setting an anti-collision unit, when the distribution cabinet is hit by the outside, the buffer plate squeezes the buffer spring and the buffer rod, thereby reducing the impact on the distribution cabinet. However, this device is difficult to automatically detect the main switch and cut off the power in time when the internal circuit is overloaded, which can easily cause the internal temperature to be too high and cause a fire. Therefore, a distribution cabinet with a protection function is proposed to solve the above-mentioned problem. Summary of the invention

[0016] See also Figure 1-Figure 7 On the basis of the above embodiment, in another embodiment of the present invention, the anti-collision mechanism 8 includes an anti-collision baffle 802, a rain shield 803, a fixing sleeve 804 and an extension rod 805. The anti-collision baffle 802 is fixedly connected to the end of the elastic telescopic column 801 away from the cabinet 1. When a car or a large object hits the cabinet 1 outside, the object will shrink inward when it hits the anti-collision baffle 802. The inward contraction of the anti-collision baffle 802 drives the elastic telescopic column 801 away from the end of the cabinet 1 to move inward and rebound, thereby reducing the external impact force on the cabinet 1. The rain shield 803 is fixedly connected to the top of the cabinet 1, and the extension rod 805 is fixedly connected to the anti-collision baffle 802 near the end. Near one end of the cabinet body 1, the fixed sleeve 804 is slidably connected to the circumferential surface of the extension rod 805; at the same time, when the anti-collision baffle 802 contracts, it will drive the extension rod 805 near one end of the cabinet body 1 to move inward, and the inward movement of the extension rod 805 will cooperate with the fixed sleeve 804 slidably connected to the circumferential surface to self-lock the cabinet door 5 to prevent the cabinet door 5 and internal devices from being bounced off during a collision, so that the cabinet body 1 can be better protected, the circumferential surface of the extension rod 805 is slidably connected to the inner wall of the cabinet body 1, and the circumferential surface of the fixed sleeve 804 is fixedly connected to the rear part of the cabinet door 5; the number of the fixed sleeves 804 is set to four, and the four fixed sleeves 804 are distributed in a rectangular array at the rear part of the cabinet door 5.

[0017] The fixing mechanism 9 includes a connecting rod 901, a rotating rod 902, an outer bracket 903, a telescopic rod 904, a fixed support leg 905 and a torsion spring group 906. The connecting rod 901 is fixedly connected to the front of the anti-collision baffle 802, the rotating rod 902 is rotatably connected to the right front end of the connecting rod 901, the outer bracket 903 is fixedly connected to both sides of the cabinet 1, and the telescopic rod 904 is slidably connected to the inner wall of the outer bracket 903. When the anti-collision baffle 802 shrinks inward, it will drive the connecting rod 901 fixedly connected at the front to move. The movement of the connecting rod 901 will drive the rotating rod 902 rotatably connected to the right front to move. The movement of the rotating rod 902 drives the telescopic rod 904 rotatably connected through the connecting rod 901 to move outward, so that the telescopic rod 904 performs a The supporting effect is to prevent the cabinet 1 from tilting. The torsion spring group 906 is fixedly connected to the top of the telescopic rod 904, and the fixed support leg 905 is rotatably connected to the circumferential surface of the torsion spring group 906; at the same time, when the telescopic rod 904 moves outward, the torsion spring group 906 fixedly connected to the outer surface will rotate, and the rotation of the torsion spring group 906 will drive the fixed support leg 905 connected to the circumferential surface to open and increase the grip on the ground, thereby increasing the grip of the telescopic rod 904 on the ground and better improving the stability of the cabinet 1. The outer surface of the outer bracket 903 is in contact with the rotating rod 902, and the telescopic rod 904 is rotatably connected to the rotating rod 902 through the connecting rod 901; the number of the outer bracket 903 is set to four, and the four outer brackets 903 are arranged in a rectangular array on both sides of the cabinet 1.

[0018] Working principle: When a car or a large object hits the cabinet 1 outside, the object will shrink inward when hitting the anti-collision baffle 802. The inward shrinkage of the anti-collision baffle 802 drives the elastic telescopic column 801 away from the end of the cabinet 1 to move inward and rebound, thereby reducing the external impact force on the cabinet 1. At the same time, the contraction of the anti-collision baffle 802 will drive the outrigger rod 805 close to the end of the cabinet 1 to move inward. The inward movement of the outrigger rod 805 will cooperate with the fixed sleeve 804 slidably connected to the circumferential surface to self-lock the cabinet door 5 to prevent the cabinet door 5 and internal devices from being bounced off during a collision, thereby providing better protection for the cabinet 1.

[0019] When the anti-collision baffle 802 contracts inward, it will drive the connecting rod 901 fixed at the front to move. The movement of the connecting rod 901 will drive the rotating rod 902 connected to the right front to move. The movement of the rotating rod 902 drives the telescopic rod 904 connected to the ground through the connecting rod 901 to move outward, so that the telescopic rod 904 can support the ground to prevent the cabinet 1 from tilting. At the same time, when the telescopic rod 904 moves outward, the torsion spring group 906 fixed on the outer surface will rotate. The rotation of the torsion spring group 906 will drive the fixed support leg 905 connected to the circular surface to open and increase the grip on the ground, thereby increasing the grip of the telescopic rod 904 on the ground and better improving the stability of the cabinet 1.

The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention. All components not specified in this embodiment can be implemented by existing technologies.
