[0034] In the accompanying drawings, the same parts use the same reference numerals. The drawings are not drawn to scale. Detailed Implementation

[0035] To make the technical solutions and advantages of the present invention clearer, exemplary embodiments of the present invention will be described in further detail below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not an exhaustive list of all embodiments. Furthermore, without conflict, the embodiments and features in the embodiments of the present invention can be combined with each other.

[0036] Embodiments of the present invention provide a hoisting chamber device for mines. For example... Figures 1 to 5As shown, the mine hoisting device includes a vertical support plate 1. A guide plate 2 is fixed to the vertical support plate 1. The guide plate 2 and the vertical support plate 1 can be separate components or integrally formed components. A cabin 6 is provided on the outer side of the guide plate 2. Sensors (not shown in the figure) and signal transmitters (not shown in the figure) are provided on the cabin 6. A top fixing plate 3 is fixedly connected to the top wall of the vertical support plate 1. A hoist 4 is fixedly installed on the top fixing plate 3. A winding roller 5 is fixed to the output shaft of the hoist 4. A steel wire rope 7 is wound on the winding roller 5. An opening is provided on the top fixing plate 3. The end of the steel wire rope 7 passes through the opening and is fixedly connected to the upper side wall of the cabin 6.

[0037] When the cabin 6 needs to be lifted, the hoist 4 is activated. The output shaft of the hoist 4 drives the winding roller 5 to rotate, winding the wire rope 7 and causing the cabin 6 to move upward. Similarly, when the cabin 6 needs to move downward, the hoist 4 drives the winding roller 5 to reverse and release the wire rope 7, thus causing the cabin 6 to move downward. It is evident that the above setup ensures that the cabin 6 can move up and down, thereby enabling the lifting and lowering of goods or personnel within the mine. Furthermore, various sensors can be installed inside the cabin 6 to monitor various conditions within the mine. The monitoring data collected by the sensors is then transmitted to the repeater 13 via a signal transmitter. The repeater receives the incoming signal, amplifies it, and then transmits it, extending the signal transmission distance and effectively overcoming the problem of signal attenuation during transmission, ensuring that the signal can be transmitted to the ground monitoring center or control station.

[0038] In one embodiment, connecting blocks 19 are provided on the cabin 6. There are two connecting blocks 19, spaced laterally apart. Rollers 8 are rotatably mounted on the back wall of each connecting block 19. Guide grooves 9 are formed on both outer walls of the guide plate 2. The guide grooves 9 extend vertically. The outer sides of the rollers 8 are embedded in the guide grooves 9. During the movement of the cabin 6 relative to the vertical support plate 1, the rollers 8 roll up and down within the guide grooves 9, creating a limiting effect on the cabin 6, thereby ensuring the smooth vertical movement of the cabin 6 and preventing swaying, deviation, or other problems.

[0039] The sensors inside cabin 6 can be one or more of the following: humidity, temperature, gas content and concentration, and cabin movement, for corresponding monitoring within the mine. For example, the sensors are connected to a data acquisition unit. The data acquisition unit collects the data monitored by the sensors and transmits it wirelessly or via cable to repeater 13. Repeater 13 receives the incoming signal, amplifies it, and then transmits it again, which can extend the transmission range and overcome the problem of signal attenuation during transmission.

[0040] The transmission distance of sensors or wireless devices is far insufficient to cover the entire mine. In this application, multiple repeaters 13 are installed, spaced vertically along the vertical support plate 1, forming a cascaded repeater string. The cascaded repeaters 13 can relay signals to the ground monitoring center or control station. A data acquisition unit connects to one of the repeaters 13 wirelessly or by cable, and that repeater 13 then passes the signal to the next repeater 13. In this way, the signal is transmitted sequentially through the connected repeaters 13 and finally sent to the ground monitoring center or control station. The main function of the repeater 13 is to receive the signal, amplify it, reshape it (for digital signals, remove noise and restore the original waveform), or regenerate it, and then forward the processed signal. Each additional repeater 13 extends the effective transmission distance. Therefore, by cascading a sufficient number of repeaters 13, theoretically, signals can be transmitted over very long distances, far exceeding the capabilities of a single transmission segment or a single device.

[0041] A scraper 14 is provided at the top of the repeater 13. The scraper 14 can be driven by a transmission assembly, which converts the vertical movement of the cabin 6 into lateral movement, thereby pushing the scraper 14 to scrape away the dust at the top of the repeater 13. The transmission assembly includes a connecting block 19, a first right-angle plate 11, a second right-angle plate 18, a trapezoidal block 17, and an elastic reset member 27.

[0042] Specifically, the repeater 13 has a groove. A second right-angle plate 18 is slidably disposed within the groove. A trapezoidal block 17 is fixedly connected to the end of the second right-angle plate 18. The trapezoidal block 17 can be an isosceles trapezoid. After installation, the curved surface of the trapezoidal block 17 faces the guide plate 2. A notch is provided on the side wall of the repeater 13. A symmetrically arranged ramp 15 is provided on the top wall of the housing of the repeater 13, that is, the top surface of the repeater 13 is constructed in a herringbone shape. A cylinder 16 is fixedly connected to the end of the second right-angle plate 18. A scraper 14 that contacts the ramp 15 is fixedly connected to the outer wall of the cylinder 16. There can be one or more scrapers 14. An elastic reset member 27 is fixedly connected between the second right-angle plate 18 and the inner wall of the notch. The elastic reset member 27 can be a spring.

[0043] Meanwhile, a first right-angle plate 11 is fixedly connected to the outer wall of the connecting block 19 located on the same side as the repeater 13. The first right-angle plate 11 extends toward the repeater 13. A cutting bevel 12 is provided at the end of the first right-angle plate 11.

[0044] The contact between the cutting inclined surface 12 and the upper inclined surface of the isosceles trapezoidal block 17 pushes the trapezoidal block 17 to move laterally. During the use of the mine hoisting chamber device, when the chamber 6 moves upward, the cutting inclined surface 12 of the first right-angle plate 11 contacts the inclined surface of the isosceles trapezoidal block 17. The lower end of the first right-angle plate 11 has a larger cross-sectional thickness. As the first right-angle plate 11 moves upward, it pushes the isosceles trapezoidal block 17, the second right-angle plate 18, and the scraper 14 to move laterally outward. The scraper 14 moves along the slope 15 to scrape off the impurities and dust adhering to the upper surface of the repeater 13 housing. In addition, the slope 15 of the repeater 13 itself has a guiding effect on dust and impurities, which on the one hand prevents the accumulation of dust and impurities, and on the other hand, the dust and impurities can be quickly removed by means of the guiding effect when the scraper 14 moves. If dust accumulates and covers the surface of repeater 13, forming a shielding layer, it directly hinders the transmission / reception of electromagnetic waves. Simultaneously, dust accumulation on the housing surface of repeater 13 prevents the housing from fully interacting with the outside air, affecting heat dissipation. Therefore, the above measures prevent dust and impurities from affecting the heat dissipation and signal transmission of repeater 13.

[0045] The top surface of repeater 13 is coated with a nano-ceramic composite coating. This nano-ceramic composite coating can effectively prevent dust from accumulating on the top surface of repeater 13.

[0046] A hatch is located on the front of compartment 6. A hatch door is rotatably installed on the inner wall of the hatch. A transparent observation port is provided on the hatch door. Opening the hatch door allows entry into the interior of compartment 6, facilitating personnel access, or for storing ores or other materials. The transparent observation port also allows observation of the interior of compartment 6.

[0047] Ventilation openings 21 are provided on the side walls of the chamber 6. A filter screen is fixedly connected to the inner wall of the ventilation openings 21. An electric push rod 20 is fixedly connected to the outer wall of the chamber 6. A cleaning plate 25 that contacts the outer wall of the filter screen is fixedly connected to the output end of the electric push rod 20. During the operation of the chamber 6, the filter screen can filter the air entering the chamber 6, removing a certain amount of floating dust and impurities, making the air entering the chamber 6 relatively clean. To achieve continuous air filtration, the electric push rod 20 can be made to reciprocate. The electric push rod 20 drives the cleaning plate 25 to move back and forth, scraping off the floating dust and impurities adhering to the surface of the filter screen, allowing airflow to pass smoothly.

[0048] A fixed pipe 22 is fixedly connected to the outer wall of the cabin 6. The fixed pipe 22 can be sleeved on the outer wall of the output end of the electric push rod 20. An annular airbag layer 23 is fixedly connected to the inner wall of the fixed pipe 22. An extrusion plate 24 is fixedly connected to the outer wall of the output shaft of the electric push rod 20. The extrusion plate 24 is a flat and elongated shape with a thicker top and a flatter bottom. For example, two extrusion plates 24 are symmetrically arranged on the outer wall of the output shaft of the electric push rod 20. A connecting pipe 26 is fixedly connected to the outer wall of the airbag layer 23. The end of the connecting pipe 26 passes through the fixed pipe 22 and the cabin 6, extending into the interior of the cabin 6. Cooling water is filled inside the connecting pipe 26 and the airbag layer 23. A piston rod 10 is slidably inserted into the end of the connecting pipe 26. A return spring is fixedly connected between the end of the piston rod 10 and the inner wall of the connecting pipe 26. Multiple heat-conducting copper plates are fixedly embedded in one end of the connecting pipe 26 located inside the cabin 6. As the electric push rod 20 moves the cleaning plate 25 downward, the squeezing plate 24 moves downward simultaneously. The squeezing plate 24 enters between the airbag layer 23 and the output shaft of the electric push rod 20. The upper end of the squeezing plate 24 is thicker. As the squeezing plate 24 moves downward, it deforms the airbag layer 23, pushing the cooling water inside the airbag layer 23 into the connecting pipe 26. After the squeezing plate 24 moves upward, the airbag layer 23 returns to its original position, and the return spring pulls the piston rod 10 back. The cooling water flows in the opposite direction into the airbag layer 23, realizing the reciprocating flow of the cooling water. During the flow, it can absorb and dissipate the heat inside the chamber 6. The end of the connecting pipe 26 can directly contact the outer wall of the sensor, directly absorbing and dissipating the heat generated by the sensor's operation, ensuring a healthy operating temperature for the sensor.

[0049] The end of the connecting tube 26 can also be changed to a multi-port tube, thus allowing it to contact the outer walls of multiple sensors. This configuration ensures a healthy operating environment for multiple sensors.
