[0002] The distribution cabinet (box) is divided into power distribution cabinet (box), lighting distribution cabinet (box), and metering cabinet (box). It is the final equipment of the power distribution system. The distribution cabinet is a general term for the motor control center. The distribution cabinet is used in places where the load is relatively dispersed and there are fewer circuits; the motor control center is used in places where the load is concentrated and there are more circuits. They distribute the power 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.

[0003] In coal mines, power distribution cabinets are usually used to supply power to the lighting system inside the coal mine to ensure the operation of the lighting system. However, the existing power distribution cabinets usually plug the cables directly into the sockets of the power distribution cabinets. In coal mines, it is easy for people to accidentally bump into them, causing the lighting system to be paralyzed and damage to the power distribution cabinets. This is very inconvenient. Therefore, we need a device to solve the problem that the cables are easily pulled out, causing the lighting system to be paralyzed and the power distribution cabinets to be damaged.

[0020] Embodiment 1: Figure 1 , Figure 2 , Figure 3 , Figure 4 The overall structure of an automated safety protection device for an underground working face in a coal mine is shown. The device is mainly composed of two important structures, namely a distribution cabinet 1 and a wire crimping device and a wire winding device. They are all fixed on the same side of the distribution cabinet 1. The wire crimping device and the wire socket 2 on the distribution cabinet 1 are on the same horizontal line, and the wire winding device is below the wire crimping device.

[0021] The wire pressing device is one of the core components, and the wire pressing device comprises: a lower wire pressing plate (3), an upper wire pressing plate (31), a screw rod (33) and a knob (32), wherein the two ends of the lower wire pressing plate (3) are fixedly connected to the power distribution cabinet (1), the upper wire pressing plate (31) is placed above the lower wire pressing plate (3), one end of the screw rod (33) is connected to the rotating shaft of the lower wire pressing plate (3), the other end of the screw rod passes through the upper wire pressing plate (31) and the end face is fixedly connected to the knob (32), an upper cushion (34) is provided on the side of the upper wire pressing plate (3) close to the lower wire pressing plate (3), and a lower cushion (35) is provided on the side of the lower wire pressing plate (3) close to the upper wire pressing plate (31), and the upper cushion (34) and the lower cushion (35) are positioned corresponding to each other. The materials of the upper cushion (34) and the lower cushion (35) are both plastic materials. The upper wire pressing plate (31) and the lower wire pressing plate 3 are supported by screw rods 33 on both sides respectively, and a cushion group composed of an upper cushion 34 and a lower cushion 35 is provided between the upper wire pressing plate (31) and the lower wire pressing plate 3 to ensure that multiple wire drawers can protect the cables from being damaged when pressing the wires.

[0022] Another core component is a winding device, which comprises: a partition (4), a winding rod (41) and a pressure plate (42); the partition (4) is fixedly connected to the power distribution cabinet (1) and is placed below the wire pressing device; a winding rod (41) is provided between adjacent partitions (4); both ends of the winding rod (41) are fixedly connected to the partition (4); the pressure plate (42) is annular; the pressure plate (42) is sleeved on the winding rod (41) and is slidably connected to the winding rod (41); a spring (43) is wound on the winding rod (41); one end of the spring (43) is connected to the partition (4); and the other end of the spring (43) is connected to the pressure plate (42). There are also multiple combinations of the winding rod 41 and the partition 4, so that each cable can be wound on the winding rod 41 separately. After the wire is wound, the pressure plate 42 will press the cable roll under the force of the spring 42 to ensure that the cable will not automatically loosen, making the winding device more stable. The partition (4) is provided with a protective cover (44), and the protective cover (44) is connected to the rotating shaft of the partition (4). The protective cover (44) is provided with a magnetic strip. The outer surface of the partition (4) is made of metal. The magnetic strip on the protective cover 44 allows it to be adsorbed on the partition, protecting the rolled cable from being kicked by people. The transparent protective cover 44 not only provides protection, but also allows easy observation of the situation on the winding rod 41.

[0023] Working principle: First, we check the length of the cable to be installed, manually move the position of the pressure plate 42, wind the excess length around the winding rod 41, and then release the pressure plate 42. Under the action of the spring 43, the pressure plate 42 fixes the cable. After the winding is completed, pass the cable through the upper cushion 34 and the lower cushion 35 and insert it into the wire plug port 2. Wind the cable in accordance with the above steps, insert the wire harness to be installed into the wire plug port 2, and then rotate the two knobs 32 at the same time. Driven by the two screws 33, the upper wire pressing plate 31 gradually moves to the lower wire pressing plate 3 until the cable is tightened.

[0024] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
