Description

Technical Field

[0001] This utility model relates to the field of intrinsically safe switch technology, specifically to an intrinsically safe switch for mining applications. Background Technology

[0002] Intrinsically safe, also known as intrinsically safe, is a type of explosion-proof electrical equipment. It limits the energy of electrical sparks or thermal effects that may be generated inside the equipment and in connecting wires exposed to potentially explosive environments to a level that cannot cause ignition. Intrinsically safe switches are a special type of industrial switch designed to achieve safe and reliable industrial control networks in flammable, explosive, and other hazardous locations. They are widely used in underground mining operations.

[0003] However, when most existing intrinsically safe switches for mining are not in use, the power cords are often bundled together by the workers. While this method does help organize the power cords to some extent, the bundled power cords are still exposed to the outside environment. Exposed power cords face multiple risks in the complex underground environment: First, during transportation in narrow tunnels, the cables are very likely to rub against mine cars, equipment, or rock walls, causing damage to the insulation layer; Second, in dynamic operating environments, hanging cables may be accidentally snagged by mobile equipment, causing the interface to loosen or even the equipment to fall.

[0004] In summary, the power cords of existing intrinsically safe switches are exposed to the outside environment and are easily damaged when stored. Utility Model Content

[0005] The purpose of this utility model is to provide an intrinsically safe switch for mining, so as to solve the technical problem that the power cords of most existing intrinsically safe switches are exposed to the outside world and are easily damaged when stored.

The switch body 1 contains a circuit board, a data forwarding chip, and a data transmission module to realize data reception and transmission. The storage groove 4 is designed to provide a space for storing and organizing the power cable 2.

[0032] The storage assembly includes a base 5 disposed on one side of the top wall of the storage groove 4, an elastic restraint strap 6 disposed on the base 5, and an inverted U-shaped buckle 7 disposed at the movable end of the elastic restraint strap 6. An L-shaped storage rack 8 is symmetrically disposed on the other side of the top wall of the storage groove 4, and the L-shaped storage rack 8 can be interlocked with the inverted U-shaped buckle 7. A transition groove 13 communicating with the storage groove 4 is provided on the rear end face of the switch body 1. The power cable 2 can easily pass through the transition groove 13 into and out of the storage groove 4 for storage or use. The movable end of the elastic restraint strap 6 is provided with an inverted U-shaped U-shaped buckle. The buckle 7 facilitates a snap-fit ​​connection with the L-shaped storage rack 8 on the other side, thereby firmly fixing the power cable 2 in the storage groove 4. In the initial state, the movable end of the elastic restraint strap 6 is snapped onto the L-shaped storage rack 8 by the U-shaped buckle 7. At this time, the elastic restraint strap 6 is in a certain deformation state, ensuring that the elastic restraint strap 6 can be stably fixed on the L-shaped storage rack 8. When storing the power cable 2, the U-shaped buckle 7 is removed from the L-shaped storage rack 8, and the bundled power cable 2 is placed into the storage groove 4. Then, the U-shaped buckle 7 is re-fixed, thereby achieving the storage and restraint of the power cable 2.

[0033] In this embodiment, specifically, the bottom four corners of the switch body 1 are symmetrically provided with support feet to ensure that the switch is placed stably, and the front face of the switch body 1 is provided with indicator lights to indicate the working status of the switch, so as to facilitate real-time monitoring by maintenance personnel.

The external ports 3 include Ethernet ports, fiber optic ports, telephone line ports, etc.

[0035] In this embodiment, specifically, the elastic restraint band 6 is an elastic rubber band or elastic textile fabric, which has good flexibility and durability, can undergo a large range of deformation, and can form a good restraint on the power cable 2.

[0036] In this embodiment, specifically, guide grooves 9 are symmetrically provided on the inner walls of both sides of the receiving groove 4, and a limiting groove 10 is provided on the inner wall of one end of the receiving groove 4. A sealing panel 11 matching the limiting groove 10 is slidably arranged inside the guide groove 9. A push-pull groove is provided through one end of the sealing panel 11, and a movement groove for the sealing panel 11 is provided on the inner wall of the other end of the receiving groove 4. A positioning protrusion 12 is symmetrically provided on the bottom of the sealing panel 11 near the limiting groove 10, and a positioning groove matching the positioning protrusion 12 is provided on the inner wall of the limiting groove 10. The sealing panel 11 can close the storage groove 4 when needed to prevent dust or debris from entering. One end of the sealing panel 11 has a through-hole for easy manual operation by the user. The guide groove 9 limits and guides the movement of the sealing panel 11, ensuring the stability of the sealing panel 11 during movement. The inner wall of the other end of the storage groove 4 is provided with a movement groove for the sealing panel 11 to move, ensuring that the sealing panel 11 can slide smoothly. When the sealing panel 11 is completely closed, the positioning protrusion 12 will be locked into the positioning groove to achieve a stable lock and prevent the sealing panel 11 from accidentally sliding open.

[0037] In this embodiment, specifically, an L-shaped fixing bracket 14 is symmetrically arranged on the rear end face of the switch body 1. The L-shaped fixing bracket 14 is located on both sides of the transition groove 13. The length of the L-shaped fixing bracket 14 is less than that of the L-shaped storage bracket 8. A protective shell 15 is slidably arranged inside the L-shaped fixing bracket 14. The protective shell 15 is cylindrical and its top is closed. The outer edges of both sides of the protective shell 15 are provided with edge portions 16 that match both the L-shaped storage bracket 8 and the L-shaped fixing bracket 14. In the initial state, the protective shell 15 is stored in the storage groove 4, and its edge portions 16 are slidably inserted into the L-shaped storage bracket 8 to achieve fixation. When storing the power cable 2, the protective shell 15 is taken out and then slidably inserted into the L-shaped fixing bracket 14. The protective shell 15 can form a covering protection at the connection between the power cable 2 and the switch body 1. When the protective shell 15 is not needed, it can be conveniently stored in the L-shaped storage bracket 8.

[0038] The above-disclosed embodiments are only a few specific examples of the present utility model. However, the embodiments of the present utility model are not limited thereto. Any changes that can be conceived by those skilled in the art should fall within the protection scope of the present utility model.
