Detailed implementation manners

[0020] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the technical field to which this application belongs; the terms used in the specification of this application are only for the purpose of describing specific embodiments and are not intended to limit this application; the terms "including" and "having" and any variations thereof in the specification and claims of this application and the above drawings are intended to cover non-exclusive inclusion. The terms "first", "second", etc. in the specification and claims of this application or the above drawings are used to distinguish different objects and not to describe a specific order.

[0021] Reference to "embodiment" herein means that a particular feature, structure, or characteristic described in connection with the embodiment can be included in at least one embodiment of this application. The phrase does not necessarily refer to the same embodiment every time it appears in the specification, nor is it an independent or alternative embodiment mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0022] An embodiment of the present utility model provides a wire arrangement structure for an underground power supply device, as Figures 1-4 shown. The wire arrangement structure of the underground power supply device includes: a wire arrangement board 1 assembled and detachable inside the main body 16 of the underground power supply device; a plurality of clamping blocks 2 symmetrically arranged on the wire arrangement board 1 with adjustable spacing, and the corresponding clamping blocks 2 are used for clamping the power cord; a plurality of sleeves 14 fixed on the wire arrangement board 1; a wire tube 15 assembled on the corresponding sleeve 14, and the wire tube 15 is used for passing the power cord in and out; an adjusting mechanism arranged on the wire arrangement board 1 for adjusting the spacing of the clamping blocks 2; a limiting mechanism arranged on the wire arrangement board 1 for limiting.

[0023] It should be noted that the underground working environment is relatively enclosed and the space is limited. The criss-crossing of power cords undoubtedly exacerbates this sense of space congestion. The messy power cords not only destroy the cleanliness of the work site, but also may bring a sense of psychological depression to workers, affecting work efficiency and operation quality. An orderly and clean working environment is crucial for improving workers' work enthusiasm and overall operation efficiency. The criss-crossing of power cords makes it necessary for workers to spend extra time and energy to sort out the lines when performing equipment maintenance or repair. This not only increases the work burden, but also may cause equipment damage or safety accidents due to misoperation. In case of an emergency, such as a sudden equipment failure that requires immediate repair, this chaotic line layout may delay the emergency repair time and cause unnecessary losses to the production of the mine. In summary, a wire arrangement structure for an underground power supply device is needed to solve the above problems;

[0024] In this embodiment, the flexible printed circuit board 1 serves as the basis of the entire flexible cable structure and is assembled within the main body 16 of the underground power supply device. Its detachable design facilitates maintenance, replacement, or adjustment when needed, improving the flexibility and maintainability of the flexible cable structure and reducing the overall replacement cost caused by damage to the flexible printed circuit board. The clamping blocks 2 are symmetrically arranged on the flexible printed circuit board 1 with adjustable spacing. Workers can adjust the distance between the clamping blocks according to the quantity and thickness of the power cables to clamp the power cables, ensuring that the power cables are firmly fixed and preventing them from sagging and falling off. The sleeve 14 is fixed on the flexible printed circuit board 1, and the wire conduit 15 is assembled on the corresponding sleeve 14. The power cables enter and exit orderly by passing through the wire conduit 15, which not only protects the power cables from external damage but also keeps the flexible cable neat, reduces direct contact and friction between the power cables, and extends the service life of the power cables. The adjustment mechanism is arranged on the flexible printed circuit board 1 to control the spacing of the clamping blocks 2, and the limit mechanism is also arranged on the flexible printed circuit board 1 to limit the position of the flexible printed circuit board 1 and maintain its stability.

[0025] In a further preferred embodiment of the present utility model, the adjustment mechanism includes: a mounting block 3 arranged on one side of the corresponding clamping block 2, the bottom of the mounting block 3 being fixedly connected to the flexible printed circuit board 1; a sliding rod 4 slidably mounted on the mounting block 3, one end of the sliding rod 4 being fixedly connected to the corresponding clamping block 2; and a spring 5 sleeved on the sliding rod 4.

[0026] In this embodiment, regarding the specific design of the adjustment mechanism, it includes components such as the mounting block 3, the sliding rod 4, and the spring 5. The coordinated action of these components enables the spacing of the clamping blocks 2 to be flexibly adjusted and maintained stably. The mounting block 3 is arranged on one side of the corresponding clamping block 2, and its bottom is fixedly connected to the flexible printed circuit board 1. This design ensures the stability and fixity of the mounting block 3, providing a reliable support point for the sliding of the sliding rod 4. The mounting block 3 serves as the base of the sliding rod 4, allowing the sliding rod 4 to slide smoothly along a predetermined trajectory, thereby driving the clamping block 2 to move and realizing the adjustment of the spacing. The sliding rod 4 is slidably mounted on the mounting block 3, and one end of it is fixedly connected to the corresponding clamping block 2. This design allows the sliding rod 4 to slide freely within the mounting block 3, thereby driving the clamping block 2 to move. The sliding function of the sliding rod 4 is the key to realizing the adjustment of the spacing of the clamping blocks 2. The spring 5 is sleeved on the sliding rod 4, and the spring 5 plays a role of resetting and maintaining force in the adjustment mechanism. When the sliding rod 4 is moved to adjust the spacing of the clamping blocks 2, the spring 5 will be compressed or stretched; when the external force disappears, the spring 5 will return to its original state, thereby driving the sliding rod 4 and the clamping block 2 back to the preset position or maintaining the current position stable.

[0027] In a further preferred embodiment of the present utility model, the limiting mechanism includes: mounting brackets 6 fixed at both ends of the cable arranging board 1; a limiting plate 7 arranged on one side of the mounting bracket 6, the limiting plate 7 being used for supporting and limiting; a bearing seat 8 fixed on the limiting plate 7; a screw rod 9 rotatably mounted on the bearing seat 8, the thread of the screw rod 9 passing through the mounting bracket 6; a knob 11 fixed at one end of the mounting bracket 6; and a guide rod 10 slidably mounted on the mounting bracket 6, one end of the guide rod 10 being fixedly connected to the limiting plate 7.

[0028] In this embodiment, regarding the specific design of the limiting mechanism, through the ingenious combination of components such as the mounting bracket 6, the limiting plate 7, the bearing seat 8, the screw rod 9, the knob 11, and the guide rod 10, effective limiting and stable support for relevant components or power lines on the cable arranging board 1 are achieved; the mounting brackets 6 are fixed at both ends of the cable arranging board 1, serving as the basic support structure of the entire limiting mechanism; the limiting plate 7 is arranged on one side of the mounting bracket 6 for support and limitation, the bearing seat 8 is fixed on the limiting plate 7, and the screw rod 9 is rotatably mounted on the bearing seat 8, its thread passing through the mounting bracket 6. By rotating the screw rod 9, the limiting plate 7 can be driven to slide along the guide rod 10 on the mounting bracket 6, thereby adjusting the position of the limiting plate 7. This design allows users to flexibly adjust the position of the limiting plate 7 as needed to limit the position of the cable arranging board 1 and maintain its stability.

[0029] In a further preferred embodiment of the present utility model, an arc-shaped groove is provided on the clamping block 2, and an insulating pad 12 is provided on the inner wall of the arc-shaped groove, and the insulating pad 12 is made of rubber material.

[0030] In this embodiment, the improved design of the clamping block 2 is specifically reflected in the addition of an arc-shaped groove and the setting of an insulating pad 12 made of rubber material on the inner wall of the arc-shaped groove; the arc-shaped groove is provided on the clamping block 2, and its shape matches the outer contour of the power line (especially the cable). The design of the arc-shaped groove enables the clamping block 2 to clamp the power line more tightly and stably. Since the arc-shaped groove coincides with the shape of the power line, it can reduce the gaps and looseness during the clamping process, improving the tightness and stability of the clamping. The insulating pad 12 is provided on the inner wall of the arc-shaped groove and is made of rubber material. The rubber material has good insulation performance and elasticity, which can effectively isolate the current and reduce friction.

[0031] In a further preferred embodiment of the present utility model, an anti-slip pad 13 is fixedly installed on one side of the limiting plate 7. The anti-slip pad 13 is made of VEA material, and anti-slip lines are provided on the contact surface between the anti-slip pad 13 and the inner wall of the underground power supply device main body 16.

[0032] In this embodiment, the improved design of the limiting plate 7 is specifically reflected in that an anti-slip pad 13 made of VEA material is fixedly installed on one side thereof, and anti-slip lines are provided on the contact surface with the inner wall of the underground power supply device main body 16. The anti-slip pad 13 is made of VEA material and is fixedly installed on one side of the limiting plate 7. The VEA material has good wear resistance, anti-aging property and elasticity, which can ensure that the anti-slip pad 13 maintains stable anti-slip performance during long-term use. The existence of the anti-slip lines further enhances the anti-slip effect of the anti-slip pad 13. When the limiting plate 7 is in close contact with the inner wall of the power supply device main body 16, the anti-slip lines can increase the contact area and friction force between the two, thereby more effectively preventing sliding or displacement.

[0033] In a further preferred embodiment of the present utility model, a sliding hole is formed in the mounting block 3, the sliding hole is adapted to the sliding rod 4, a limiting piece is fixedly installed at one end of the sliding rod 4, and the limiting piece is larger than the inner diameter of the sliding hole.

[0034] In this embodiment, the connection design between the mounting block 3 and the sliding rod 4 is specifically reflected in the adaptability of the sliding hole formed in the mounting block 3 to the sliding rod 4, and the limiting piece fixedly installed at one end of the sliding rod 4. The sliding hole is formed in the mounting block 3, and its shape and size match the outer contour of the sliding rod 4 to ensure that the sliding rod 4 can smoothly pass through the sliding hole and slide along it. The limiting piece is fixedly installed at one end of the sliding rod 4, and its size is larger than the inner diameter of the sliding hole. This means that the limiting piece cannot pass through the sliding hole, thereby playing a role in preventing the sliding rod 4 from falling off the mounting block 3.

[0035] In a further preferred embodiment of the present utility model, a threaded hole and a guiding hole are formed in the mounting bracket 6, the threaded hole is adapted to the screw rod 9, and the guiding hole is adapted to the guiding rod 10.

[0036] In this embodiment, the design of the mounting bracket 6 is specifically reflected in the threaded hole and the guiding hole formed thereon. These two holes are respectively adapted to the screw rod 9 and the guiding rod 10. The threaded hole is formed in the mounting bracket 6, and its shape and size match the thread of the screw rod 9. The cooperation of the threaded hole and the screw rod 9 ensures the stability and reliability of the connection of the mounting bracket 6. The guiding hole is also formed in the mounting bracket 6, and its shape and size match the guiding rod 10. The guiding rod 10 can smoothly pass through the guiding hole and slide or rotate in it along a specific direction.

[0037] In a further preferred embodiment of the present utility model, the surface of the wire arranging board 1 is covered with a fireproof insulating coating, the coating is made of polytetrafluoroethylene material, and the wire pipe 15 is made of PE flame retardant material.

[0038] In this embodiment, the materials and surface treatments of the flexible cable board 1 and the wire tube 15 are optimized. Specifically, it is reflected in the fireproof and insulating coating covered on the surface of the flexible cable board 1 and the PE flame-retardant material used for the wire tube 15. A layer of fireproof and insulating coating is covered on the surface of the flexible cable board 1. This coating is made of polytetrafluoroethylene (PTFE) material. Polytetrafluoroethylene has excellent high-temperature resistance, corrosion resistance, wear resistance and insulation properties, and can maintain stable physical and chemical properties in high-temperature environments. By covering the fireproof and insulating coating, the safety performance of the flexible cable board 1 has been significantly improved. This design not only helps to reduce the damage to circuits and power supply equipment caused by accidents such as fires, but also can improve the overall reliability and service life of the equipment.

[0039] In summary, the detachable design of the flexible cable board 1 allows for easy maintenance, replacement or adjustment when needed, significantly improving the flexibility and maintainability of the cable structure, reducing the overall replacement cost. The adjustable spacing design of the clamping blocks 2, combined with the arc-shaped grooves and the rubber insulating pads 12, ensures that the power cables are firmly clamped, avoiding the risk of sagging and falling off, while keeping the power cables clean and safe. The combined use of the sleeve 14 and the wire tube 15 not only protects the power cables from external damage, but also reduces the direct contact and friction between the power cables, thereby extending the service life of the power cables. The adjustment mechanism realizes the precise adjustment and stable maintenance of the spacing between the clamping blocks 2 through the coordinated action of the mounting block 3, the sliding rod 4 and the spring 5.
