Technical Field

[0001] The present application relates to the field of mine communications, and in particular to a leaky cable covering system for a mine working face. Background Art

[0002] Communication within mine workings plays a vital role in mining operations. A good signal environment is essential for underground personnel and equipment to communicate with the outside world. Currently, signal transmission is primarily achieved through the installation of base stations and antennas within the workings. However, due to the complex geological environment, electromagnetic interference, dust interference, and signal obstruction by large equipment within the workings, signal strength within the workings is reduced. Therefore, improving signal strength and coverage within the workings becomes a challenge. Summary of the Invention

[0003] In order to improve the signal strength and coverage range within the working face of a mine, the present application provides a mine leaky cable covering system for the working face of a mine.

[0004] This application provides a mine working face leaky cable covering system, which adopts the following technical solutions:

[0005] A mine working face leaky cable covering system, comprising

[0006] Multiple hydraulic supports are evenly distributed along the mine tunnel;

[0007] A plurality of hooks are provided on the shield beams of the plurality of hydraulic supports, and each hydraulic support has a corresponding hook;

[0008] a leakage cable, arranged on the plurality of hooks;

[0009] The base station is connected to the leaky cable via a feeder line and sends and receives communication signals via the leaky cable.

[0010] By adopting the above technical solution, the hydraulic support is used to support the mine working face to prevent accidents such as collapse of the mine working face. The hook set on each hydraulic support is used to fix the leakage cable. The leakage cable is fixed in the hook. The base station is connected to the leakage cable through a feeder. The base station sends and receives communication signals through the leakage cable. The communication signal is transmitted along the working face to the inside of the working face through the leakage cable. The signal strength at each point on the leakage cable is relatively consistent. The communication signal is radiated to the space inside the mine working face through the leakage cable. Compared with setting an antenna in the mine working face, the signal transmission is more stable and the communication signal is transmitted through the leakage cable as a medium, which makes the signal strength higher.

[0011] Optionally, the base station is communicatively connected to a repeater unit, the repeater unit is communicatively connected to a baseband processing unit, the baseband processing unit is communicatively connected to a ring network switch, and the ring network switch is communicatively connected to a server.

[0012] By adopting the above technical solution, repeater units, baseband processing units, ring network switches and other equipment are used to modulate and demodulate signals, and enhance and compensate for signal attenuation during transmission to ensure signal quality within the coverage area. The server can easily receive data sent by equipment, sensors and personnel terminal devices within the mine working surface, and can store and process the sent and received data.

[0013] Optionally, a slide rail is provided on the shielding beam of each hydraulic support, a base is slidably connected to the slide rail, a screw is threadedly connected to the base, the screw passes through the base and abuts against the slide rail, and the hook is provided on the base.

[0014] By adopting the above technical solution, since the height of the hydraulic support may need to be adjusted in the vertical direction when the hydraulic support is working, a slide rail is set on the shielding beam, and the base moves on the slide rail to adjust the height of the leakage cable, so that the leakage cable can be easily adjusted to the optimal height or the required height. After adjusting to the optimal height or the required height, the screw is rotated, and the screw is rotated to gradually tighten the slide rail, so that the base is not easy to loosen on the slide rail.

[0015] Optionally, a handle is provided on the screw rod.

[0016] By adopting the above technical solution, it is more convenient and labor-saving for the staff to rotate the screw by turning the handle.

[0017] Optionally, the hook includes a base plate, a first snap ring and a second snap ring arranged on the base plate, the second snap ring is hingedly connected to a connecting plate at one end away from the base plate, the connecting plate is provided with a first hook, and the first snap ring is provided with a second hook at one end away from the base plate.

[0018] By adopting the above technical solution, when arranging the cable, the staff can place the leakage cable between the first clamping ring and the second clamping ring, and then the staff uses the first hook to hang the second hook, so that the first hook and the first hook are clamped and locked to each other, and the side with better radiation effect of the leakage cable signal faces the working surface. Due to the clamping of the hook, the leakage cable is not easy to rotate, and the radiation signal of the leakage cable is more stable.

[0019] Optionally, a waterproof layer is provided on the surface of the leaking cable.

[0020] By adopting the above technical solution and providing a waterproof layer on the leaky cable, the leaky cable can be isolated from water, so that the leaky cable is not easily damaged by water, and thus is not easily affected by signal radiation.

[0021] In summary, this application includes at least one of the following beneficial technical effects:

[0022] 1. Hydraulic supports are used to support the working face of a mine and prevent accidents such as collapse. A hook installed on each hydraulic support is used to secure a leaky cable. The leaky cable is fixed in the hook. The base station is connected to the leaky cable via a feeder. The base station sends and receives communication signals via the leaky cable, which is then transmitted along the working face to the interior of the working face. The signal strength at each point on the leaky cable is relatively consistent, and the communication signal is radiated into the space within the mine working face through the leaky cable. Compared to installing an antenna within the mine working face, signal transmission is more stable, and the use of the leaky cable as a medium for transmitting communication signals results in higher signal strength.

[0023] 2. Repeater units, baseband processing units, ring network switches, and other equipment are used to modulate and demodulate signals, and enhance and compensate for signal attenuation during transmission to ensure signal quality within the coverage area. The server facilitates receiving data sent by equipment, sensors, and personnel terminal devices within the mine working surface, and facilitates the storage and processing of sent and received data.

[0029] The present application is further described in detail below with reference to the accompanying drawings.

[0030] The embodiment of the present application discloses a leaky cable covering system for a mine working face.

[0031] Reference Figure 1 and Figure 2 A mine working face leaky cable covering system includes a hydraulic support 1, a hook 2, a leaky cable 3, and a base station 4. Multiple hydraulic supports 1 are provided, and the multiple hydraulic supports 1 are evenly distributed along the working face of the mine. A hook 2 is provided on the shielding beam 11 of each hydraulic support 1, and workers place the leaky cable 3 in the hook 2 of each hydraulic support 1. The shielding beam 11 is located on the inner side of the hydraulic rod, so the leaky cable 3 is not easily interfered with on the shielding beam 11. The base station 4 can be arranged at both ends of the mine working face, and the leaky cable 3 is connected to the base station 4 for communication via a feeder. The feeder and the base station 4 are connected and fixed by a connector, and the feeder and the leaky cable 3 are also connected and fixed by a connector, thereby transmitting the communication signal sent by the base station 4. Equipment in the mine can also send signals to the base station 4 via the leaky cable 3 for communication and data transmission. Furthermore, one base station 4 can be connected to two leaky cables 3. Specifically, the base station 4 can be a 5G base station, and the communication signal transmitted by the leaky cable 3 is a 5G signal. Compared with setting antennas at the mine entrance and the depth of the mine for signal transmission, using the leaky cable 3 as a signal transmission medium is more stable and has higher strength.

[0032] Reference Figure 2 To further enhance the signal strength and stability transmitted by the leaky cable 3, the base station 4 is connected to a repeater unit 51 via optical fiber. This repeater unit 51 can be a related relay device, such as a relay gateway. It is used for line branching and signal relay and is located in the mine's substation. It is connected to a baseband processing unit 52 via optical fiber. This baseband processing unit 52 can be a related baseband processing device, such as a baseband processor. Baseband processing unit 52 processes 5G signals and is also located in the mine's substation. It is connected to a ring network switch 53 via optical fiber, which is used for data transmission. This ring network switch 53 is also connected to a server 54 via optical fiber. Various large-scale equipment, sensors, and personnel terminal devices deep within the mine all communicate via the leaky cable 3. This equipment facilitates data transmission. Furthermore, a server 54 is located outside the mine to facilitate storage and processing of data uploaded from underground.

[0033] Furthermore, an impedance matcher (not shown in the figure) is connected to the end of the leakage cable 3 in the mine to ensure signal transmission efficiency and reduce reflection.

[0034] Reference Figure 3The height of the hydraulic support 1 may need to be adjusted vertically in the mine. This adjustment may cause the height of the leaky cable 3 to change, thereby affecting the 5G signal radiation performance of the leaky cable 3. Therefore, to facilitate adjustment of the height of the leaky cable 3, a slide rail 61 is fixedly connected to the shielding beam 11. The slide rail 61 is vertically arranged along the surface of the shielding beam 11, and a base 62 is slidably connected to the slide rail 61. The hook 2 is fixedly connected to the base 62. The slide rail 61 has a T-shaped cross-section, and the bottom surface of the base 62 also has a T-shaped slot, which prevents the base 62 from falling off the slide rail 61. A screw 63 is threadedly connected to the side of the base 62. The screw 63 passes through the base 62 and abuts the side of the slide rail 61. A handle 64 is also fixedly connected to the screw 63, which allows workers to easily rotate the screw 63, saving effort. When the hook 2 needs to be adjusted to the desired height or the optimal height, the operator slides the base 62 to the designated position and then turns the handle 64. The rotation of the handle 64 drives the screw 63 to rotate. As the screw 63 rotates, it approaches the side of the slide rail 61, thereby tightening the slide rail 61 and keeping the base 62 in the designated position, making it less likely to become loose. Furthermore, to prevent the base 62 from falling off the ends of the slide rail 61, limit plates (not shown in the figure) are fixedly connected to both ends of the slide rail 61. The limit plates block the base 62, allowing the base 62 to move more smoothly on the slide rail 61 without falling off the ends of the slide rail 61.

[0035] Reference Figure 4 To prevent the leaky cable 3 from falling off the hook 2 and from rotating, the hook 2 includes a base plate 21 fixedly connected to the base 62, a first snap ring 22 and a second snap ring 23 fixedly connected to the base plate 21, a clamping plate 24 hingedly connected to the second snap ring 23 at an end away from the base plate 21, a first hook 25 fixedly connected to the clamping plate 24, and a second hook 26 fixedly connected to the first snap ring 22 at an end away from the base plate 21. Both the first snap ring 22 and the second snap ring 23 are semicircular in shape. When the staff arranges the leakage cable 3, since the area on one side of the surface of the leakage cable 3 has a better radiation signal effect, the staff directs this area toward the work surface. After the staff sets the position and direction of the leakage cable 3, they press the first clamping ring 22 and the second clamping ring 23. The second hook 26 on the first clamping ring 22 clamps the first hook 25 on the clamping plate 24, and the first clamping ring 22 and the second clamping ring 23 squeeze the leakage cable 3, so that the side of the leakage cable 3 with a good signal radiation effect is always facing the work surface, and the leakage cable 3 is not easy to rotate, so that the leakage cable 3 always maintains a good signal radiation effect.

[0036] Reference Figure 4Furthermore, in order to facilitate the staff to use the hook 2, a third hook 27 is fixedly connected to the end of the clamping plate 24 away from the second clamping ring 23. When the leakage cable 3 needs to be loosened, in order to prevent the leakage cable 3 from falling off the hook 2, the staff can press the first clamping ring 22 to make the second hook 26 on the first clamping ring 22 disengage from the clamping fit with the first hook 25, and then rotate the clamping plate 24 to make the second hook 26 engage with the third hook 27. At this time, the clamping plate 24 and the first clamping ring 22 and the second clamping ring 23 form a closed area, and the staff can rotate, translate, retract, and other operations on the leakage cable 3 without causing the leakage cable 3 to fall off the hook 2.

[0037] To isolate the leaky cable 3 from water and reduce contact between it and the cable, a waterproof layer (not shown) is fixedly attached to the surface of the leaky cable 3. This waterproof layer can be made of waterproof tape, which can be a self-adhesive rubber tape. Before installing the leaky cable 3, workers can simply wrap the waterproof tape around the surface of the leaky cable 3. Furthermore, the connectors used to connect the leaky cable 3 to the feeder, as well as the connectors where the feeder connects to the base station 4, can also be wrapped with waterproof tape to reduce moisture ingress.

[0038] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
