Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.

[0017] Example

[0018] A coal mine power supply port protection device described in this embodiment is as follows: Figure 1 , Figure 2 and Figure 3As shown, it includes a power supply cabinet body 1, and a mounting plate 2 is provided at the port of the power supply cabinet body 1. A fixing groove consistent with the size of the port is provided on the mounting plate 2. A protective cover 5 for protecting the port is provided on the mounting plate 2. The protective cover 5 is divided into left and right lobes along its center line. A first slider 3 is fixed on both lobes. Corresponding to the first slider 3, a first slide groove that slides left and right with it is provided on the mounting plate 2. Two second slide grooves are provided on the mounting plate 2. A second slider that slides up and down with it is provided in the second slide groove. A buckle 4 for clamping the protective cover 5 is fixed on the second slider. A clamping groove is provided on the side wall of one of the clamping buckles 4, and a clamping column 8 that is clamped with the clamping groove is fixed on the side wall of the other clamping buckle 4. The protective cover 5 A through hole 6 is provided on the top for the cable of the connector to pass through. The port of the power supply cabinet body 1 is connected to the mounting plate 2 by a thread. When the protective cover 5 on the mounting plate 2 is damaged, it is convenient to replace it with a new one. The mounting plate 2 is provided with a protective cover 5, which is divided into two lobes on the left and right. Two first slide grooves distributed on the left and right are provided on the mounting plate 2. A first slider 3 is provided in the first slide groove, wherein the left lobe of the protective cover 5 is connected to the first slider 3 on the left, and the right lobe of the protective cover 5 is connected to the first slider 3 on the right, so that the two lobes can move left and right on the mounting plate 2 through the sliding cooperation of the first slide groove and the first slider 3, so as to cover the port of the power supply cabinet body 1, thereby protecting it and preventing the port from being exposed to the outside and damaged by external force;

[0019] Two second vertically arranged slots are provided on the mounting plate 2, and the second sliders in the second slots are connected to the buckles 4. The two buckles 4 can move up and down on the mounting plate 2 through the sliding cooperation of the second sliders in the second slots, and the upper buckle 4 moves from top to bottom, and the lower buckle 4 moves from bottom to top, so that the side wall structures of the two buckles 4, the clamping column 8 of the side wall of one buckle 4 is inserted into the clamping groove of the side wall of the other buckle 4, the clamping column 8 and the clamping groove are clamped with each other, and the two buckles 4 firmly fix the protective cover 5 together to prevent it from displacement;

[0020] The left and right lobes of the protective cover 5 are provided with holes in an arc-shaped structure. When the left and right side walls of the protective cover 5 are fitted together, the holes on the two lobes form a circular through hole 6, and the protective cover 5 as a whole is a cylindrical structure. When the two lobes of the protective cover 5 are separated, the cross-sections of the left and right lobes are in an "L"-shaped structure. The buckle 4 is in an arc-shaped structure, and the side wall of the buckle 4 fits with the side wall of the protective cover 5, so that the protective cover 5 can be better clamped and fixed; and magnets can be adhered to the side walls of the left and right lobes of the protective cover 5. When the left and right lobes of the protective cover 5 are close to the middle, the two lobes are adsorbed together by the magnet, so as to better protect the port of the power supply cabinet body 1;

[0021] When the connector is inserted into the port of the power supply cabinet body 1, the left and right lobes of the protective cover 5 are moved so that the left and right lobes clamp the connector, and the inner walls of the two lobes of the protective cover 5 are provided with a protective layer 7, and the inner walls of the two lobes of the protective cover 5 are adhered with the protective layer 7, and the protective layer 7 is made of silicone material, and the silicone is tightly attached to the surface of the connector, which limits the connector to a certain extent, and the silicone is soft, and when the connector is squeezed and clamped, it can also avoid damage to the connector and protect it; move the two lobes of the protective cover 5 so that the protective layer 7 on the inner wall contacts the cable connector and limits it, ensuring the stability of the connection between the cable connector and the port, and avoiding displacement or deformation of the cable connector and the port when the cable is pulled by external force, affecting the connection effect, causing circuit short circuit, etc.;

[0022] like Figure 1 , Figure 2 and Figure 3 As shown, a hinge column 13 is fixed on the protective cover 5 corresponding to the through hole 6, and a sealing plate 9 for closing the through hole 6 is hinged on the hinge column 13. A metal block 10 is arranged at the through hole 6, and a magnet 11 with a ring structure and attracting each other with the metal block 10 is arranged on the inner wall of the sealing plate 9. A hinge column 13 is welded or glued on the right petal of the protective cover 5, and a sealing plate 9 is hinged on the hinge column 13. The sealing plate 9 rotates around the hinge point to block the through hole 6. A metal block 10 is glued on the protective cover 5 at the through hole 6, wherein one block is glued on each of the two petals of the protective cover 5. When the side walls of the two petals are fitted together, the two metal blocks 10 form a circular ring structure, and a magnet is glued on the inner wall of the sealing plate 9. 11, rotate the sealing plate 9 to rotate around the hinge column 13, when the magnet 11 on the inner wall of the sealing plate 9 coincides with the metal block 10, the magnet 11 and the metal block 10 attract each other, so that the sealing plate 9 is fixed at the through hole 6 to seal it, and when the port of the power supply cabinet body 1 is not connected to the cable connector, the through hole 6 is sealed by the sealing plate 9 to prevent external dust and water vapor from entering the protective cover 5 and affecting the port; and the inner wall of the sealing plate 9 is provided with a sealing plug 12, and the inner wall of the sealing plate 9 is adhered with the sealing plug 12. When the sealing plate 9 blocks the through hole 6, the sealing plug 12 is located at the through hole 6, and the through hole 6 is further blocked to make the sealing effect better;

[0023] During actual use, the cable connector is inserted into the port of the power supply cabinet body 1, and the two petals of the protective cover 5 are moved to protect its interface. The two petals of the protective cover 5 clamp and fix the cable connector, and then the two buckles 4 are moved to clamp and fix the protective cover 5. When the side walls of the two buckles 4 fit together, the clamping column 8 is inserted into the clamping groove and clamped to each other, so that the two buckles 4 are clamped on the protective cover 5, and the position of the protective cover 5 is further limited. It can effectively cover and protect the port of the power supply cabinet body 1 to avoid damage to the port. At the same time, the cable connector is protected after the port is plugged in, thereby improving the stability of the cable connection.
