DETAILED DESCRIPTION

[0031] In order to enable those skilled in the art to better understand the present invention, the technical solution of the present invention is further described below with reference to the accompanying drawings and embodiments.

[0032] Example 1: Figure 1-11As shown, a power distribution cabinet with leakage protection of the present invention includes a power distribution cabinet 1, a copper wire 11 is connected to the inside of the power distribution cabinet 1, the copper wire 11 extends out of the power distribution cabinet 1 and is connected to a flat steel 12, a partition 13 is fixedly installed in the middle of the power distribution cabinet 1, and cabinet doors 14 are rotatably installed on both sides of the partition 13 and the power distribution cabinet 1, and a locking mechanism is installed on the cabinet door and the partition 13;

[0033] The locking mechanism includes a mounting lock body 20 fixedly mounted to the cabinet door 14, a lock core 21 rotatably mounted inside the mounting lock body 20, a coil spring 22 installed between the lock core 21 and the mounting lock body 20, a lock block 23 fixedly mounted on the lock core 21 passing through the mounting lock body 20, a lock slot 24 matching the lock block 23 is installed on the partition 13, and a detection component is installed on the upper side of the lock slot 24;

[0034] The detection component includes an electromagnet 25 electrically connected to the partition 13, the input end of the electromagnet 25 is fixedly connected to the partition 13, the output end of the electromagnet 25 is connected to the flat steel 12, and a magnet 26 is connected to the inside of the partition 13 for sliding up and down. The magnet 26 is magnetically connected to the energized electromagnet 25, and an abutment block 27 abutting against the lock block 23 is fixedly installed at the lower end of the magnet 26. A first spring 28 is installed at the upper end of the abutment block 27, and the lock core 21 is made of insulating material.

[0035] Several electrical equipment are installed inside the distribution cabinet 1, and the connection method is the existing technology. At the same time, the four internal walls of the distribution cabinet 1 are connected to the external flat steel 12 through copper wire 11, so that the grounded flat steel 12 plays a leakage protection role for the distribution cabinet 1. The above are all existing technologies and will not be repeated here. The lock cylinder 21 is made of ceramic material, and a key matching the lock cylinder 21 is provided as an unlocking key. During normal use, the key drives the lock cylinder to rotate and control the door lock. In the initial state, the rebound force of the coil spring 22 causes the lock cylinder 21 and the lock block 23 to move upward, and then causes the lock block 23 to abut against the abutment block 27. At this time, the rebound force of the first spring 28 is greater than the rebound force of the coil spring 22, so the lock block 23 is stationary. At the same time, the lock block 23 overcomes the first spring 28 and moves upward to abut against the upper side of the lock slot 24, and cannot be rotated out of the lock slot 24. When current is generated in the cabinet wall of the distribution cabinet 1, the leakage protection device will play a role. The electromagnet 25 is energized to generate a magnetic attraction, which in turn attracts the magnet 26 to overcome the first spring 28 and move upward, thereby releasing the contact with the abutment block 27. The magnet 26 is C-shaped, so that during the upward movement of the C-shaped magnet 26, the lower part will extend into the lock slot 24 to block it. When the key is inserted into the lock cylinder 21 and the lock block 24 overcomes the coil spring 22 and rotates downward, it will abut against the C-shaped magnet 26 and cannot be rotated out of the lock slot 24, thereby preventing the cabinet door 14 from being opened. Until the power is cut off inside the distribution cabinet 1 or there is no current leakage, the electromagnet 25 cannot attract the magnet 26, thereby causing the magnet 26 to be in the initial state under gravity and the rebound force of the first spring 28. This will enable the lock block 23 to rotate downward out of the lock slot 24 and pull the cabinet door 14 outward to open the distribution cabinet 1.

[0036] The present invention can use the principle that the distribution cabinet is charged to enable the electromagnet to control the magnet through the current of the distribution cabinet, so that when the current of the distribution cabinet leaks, the key cannot be used to drive the lock core and the lock block to rotate out of the lock slot, and the cabinet door cannot be opened. At the same time, the ceramic lock core can prevent the current from being directed to the key and the operator when the cabinet door is opened by the key.

[0037] Example 2: Further improvement is made on the basis of Example 1, the locking block 23 is arc-shaped on the side close to the partition 13, an arc groove 29 matching the locking block 23 is opened on the lower side of the abutment block 27, and the locking block 23 is provided with an abutment groove 30 matching the locking block 23.

[0038] The lock core 21 includes a cylinder 31 fixedly mounted on the lock block 23, and an insertion circular plate 32 connected to the coil spring 22 is fixedly mounted on the front end of the cylinder 31. An annular groove 33 is provided at the front end of the insertion circular plate 32, and a limiting groove 34 connected to the annular groove 33 is symmetrically provided on the insertion circular plate 32. The two limiting grooves 34 are provided with a card groove 35 along the direction of the reaction force of the coil spring 22. An entry groove matching the limiting groove 34 is provided at the front end of the installation lock body 20, and a color block 36 is installed on the upper end of the insertion circular plate 32 and the inside of the limiting groove 34.

[0039] In the initial state, the limiting groove 34 matches the entry groove and blocks the color block 36 on the inserted circular plate 32. At the same time, the color blocks 36 installed on the inserted circular plate 32 and the limiting groove 34 are different in color, which makes it easy to distinguish the state of the locking block 23 at this time. At this time, the abutting groove 30 abuts against the corners of the arc groove 29, which enables the locking block 23 to balance the resilience of the first spring 28 and the coil spring 22.

[0040] The arrangement of the abutting groove 30 and the arc groove 29 is such that when the abutting block 27 moves slightly upward, the side ridges of the arc groove 29 can be moved away from the rotation radius of the lock block 23, and then the electromagnet 25 is energized to release the side ridges of the arc groove 29 from the abutting groove 30, so that the lock block 23 can be rotated upward under the drive of the coil spring 22 to abut the lock groove 24, and the cylinder 31 and the insert circular plate 32 can be rotated upward, that is, the color block 36 on the insert circular plate 32 is leaked and located inside the entry groove of the limit groove 34. At the same time, after the color block 36 is located in the entry groove, the key cannot pass through the entry groove into the limit groove 34 and the card slot 35, thereby locking the locking mechanism and preventing the cabinet door 1 from being opened;

[0041] At the same time, in the initial state, the key is inserted into the limiting groove 34 and the annular groove 33 through the entry groove and then rotated downward to allow the key to enter the card slot 35, thus preventing the key from slipping out of the entry groove.

[0042] A pull rope 40 is fixedly installed at the lower end of the magnet 26, and the pull rope 30 is fixedly connected to an L-shaped slide 41 that is slidably connected to the distribution cabinet 1 back and forth. A second spring 411 is installed between the L-shaped slide 41 and the distribution cabinet 1, and the L-shaped slide 41 is transmission-connected to an auxiliary protection mechanism and an auxiliary warning mechanism.

[0043] The auxiliary protection mechanism includes a rotating shaft 42 rotatably connected to the distribution cabinet 1, a connecting plate 43 is rotatably installed on the side of the distribution cabinet 1 through the rotating shaft 42, a copper sheet 44 is fixedly installed inside the distribution cabinet 1, a grounding copper column 45 connected to the copper sheet 44 is fixedly installed on the upper end of the connecting plate 42, and the grounding copper column 45 is connected to a second flat steel 46. The distribution cabinet 1 is provided with a placement groove matching the connecting plate 43, and a baffle 47 matching the grounding copper column 45 is rotatably installed on the upper part of the placement groove, and a rotating plate 48 is fixedly installed on the rotating shaft 42.

[0044] In the initial state, the rotating plate 48 is parallel to the L-shaped slide plate 41 and abuts against each other. At this time, the connecting plate 43 is located inside the placement groove and the baffle 47 is located outside the grounding copper column 45. When the distribution cabinet 1 generates leakage, it indicates that the existing leakage protection device has a problem, and the electromagnet 25 is energized to drive the pull rope 40 to move upward, thereby causing the L-shaped slide plate 41 to move forward and release the abutment with the rotating plate 48. After the rotating plate 48 is released from the abutment, it rotates outward under the action of its own gravity, thereby causing the connecting plate 43 and the grounding copper column 45 to rotate outward and abut against the second flat steel 46. When the grounding copper column 45 rotates outward, it will drive the baffle 47 to flip upward to contact the shielding of the abutting copper column 45 and leak out of the placement groove. A heat dissipation groove is provided inside the placement groove and communicates with the interior of the distribution cabinet 1, thereby improving the heat dissipation efficiency of the distribution cabinet 1 when leakage occurs.

[0045] Insulating rubber can be installed on the side of the rotating plate 48 away from the L-shaped slide plate 41, so as to play a buffering role when the connecting plate 43 rotates and abuts against the second flat steel 46.

[0046] The auxiliary warning mechanism includes a colored light tube 50, with a conductive sheet 51 electrically connected to the upper end of the colored light tube 50. The partition 13 and the power distribution cabinet 1 both have a slot that matches the colored light tube 50, and the L-shaped slide 41 has a through hole that matches the slot. There are multiple auxiliary warning mechanisms.

[0047] When the L-shaped slide plate 41 slides forward, it will leak out of the slide groove, and then the colored lamp tube 50 will slide down and out of the distribution cabinet 1. The leakage of the partition 13 will connect the current with the conductive sheet 51, and then the current will flow through the conductive sheet 51 to the colored lamp tube 50 to light it up. In this way, when inspecting the distribution cabinet, it can be observed intuitively and at a long distance that the distribution cabinet 1 has a leakage and needs maintenance.

[0048] The chute has an arc-shaped slot 53 formed inside, and a stopper 52 is fixedly mounted on the colored lamp 50 and slides in contact with the arc-shaped slot. The stopper 52 slides in contact with the arc-shaped slot 53, so that when the colored lamp 50 slides downward, it is blocked by the stopper 52 and the arc-shaped slot 53, reducing its descent speed.

[0049] The above embodiments are merely illustrative of the principles and effects of the present invention and are not intended to limit the present invention. Anyone skilled in the art may modify or alter the above embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent modifications or alterations made by one of ordinary skill in the art without departing from the spirit and technical principles disclosed herein are intended to be covered by the claims of the present invention.
