DETAILED DESCRIPTION

[0040] The embodiments will be combined with the drawings in the specification to clearly and completely describe the technical solution of this application. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without making any creative work shall fall within the scope of protection of this application.

[0041] Example 1:

[0042] The present invention provides a multifunctional elevator wireless alarm intercom device, please refer to Figure 1-14, including an intercom device 3 arranged on the inner wall of the elevator bridge car 2, the elevator bridge car 2 is arranged in the mine 1, and the mine 1 is provided with a bridge car guide rail 11 that matches the elevator bridge car 2. Visual indicator lights are added inside and outside the elevator bridge car 2 to display the emergency help status. The intercom device 3 includes a panel 31 and a box 32. It should be noted that the box 32 passes through the elevator bridge car 2 and extends into the mine 1. The panel 31 is flush with the inner wall of the elevator bridge car 2. The outer wall of the panel 31 is provided with an operation button 311 and a touch screen 312. The operation button 311 is used for the bridge car mine layer selection function and the emergency alarm function. The touch screen 312 is used for touch operation and emergency video call function. The touch screen 312 The top is equipped with a sensor module 313, a camera module 314, and an intercom module 315. The camera module 314 is a fisheye camera with a resolution greater than 720P, which effectively ensures that all miners are within the lens's line of sight. The camera module 314 works with the touch screen 312 to realize video calls in emergency situations, which can effectively help rescuers understand the on-site conditions, provide accurate guidance, and improve emergency response efficiency. Furthermore, the touch screen 312 is equipped with integrated voice recognition technology, and a multi-language option is added to the device software, supporting English and the main local language. Natural language processing (NLP) technology is used to ensure smooth switching between different languages, facilitating barrier-free communication between miners and rescuers.

[0043] The sensor module 313 integrates an infrared sensor and a smoke sensor, which automatically identifies the fire status in the bridge compartment. For example, if the mining lamp battery or other high-risk items spontaneously combust or gas leaks in the bridge compartment, it will automatically identify it and, in an emergency, stop the hoist bridge compartment 2 at the nearest mining layer and open the door to automatically alarm.

[0044] The intercom module 315 uses a highly sensitive microphone and a high-fidelity speaker, and integrates active noise cancellation technology to filter out ambient noise and improve communication clarity in emergency situations.

[0045] For further information, see Figure 1-5 A cleaning mechanism 4 for cleaning the outer wall of the panel 31 is provided on the outer wall of the box body 32. The cleaning mechanism 4 includes two groups of main rods 41 symmetrically connected to the side walls of the box body 32. The two ends of the main rod 41 are respectively slidably connected to the second slide rod 43 and the first slide rod 42. A contraction spring 44 is fixed between the second slide rod 43 and the first slide rod 42. The contraction spring 44 has an elastic force that drives the first slide rod 42 and the second slide rod 43 to be close to each other. The opposite ends of the first slide rod 42 and the second slide rod 43 are both rotatably connected to the roller 411 to reduce the sliding friction. The end of the second slide rod 43 away from the main rod 41 is fixed with a connecting rod 431, and a dust cleaning roller 45 is rotatably connected between the two groups of second slide rods 43. The bottom of the box body 32 is provided with a driving mechanism that drives the main rod 41 to rotate back and forth at equal angles.

[0046] When the driving mechanism drives the main rod 41 to rotate, the main rod 41 uses the second sliding rod 43 and the connecting rod 431 to drive the dust cleaning roller 45 to perform a cleaning and wiping action on the surface of the panel 31. The elastic force of the contraction spring 44 is used to keep the dust cleaning roller 45 always in contact with the surface of the panel 31, thereby completing the cleaning action of the coal ash dust adhered to the surface of the panel 31.

[0047] See also Figure 3-6 It should be noted that, in this embodiment, the drive mechanism includes a transmission magnetic sleeve 48 and a reciprocating screw 46, a generator 6 is fixed to the bottom of the box 32, and two sets of backup batteries 5 are fixed on the side of the box 32 away from the panel 31. The output end of the generator 6 is electrically connected to the backup battery 5 through a rectifier, and a spline shaft 62 is provided on the input shaft of the generator 6. A spline groove 483 corresponding to the spline shaft 62 is provided in the transmission magnetic sleeve 48. An electromagnetic ring 63 matching the transmission magnetic sleeve 48 is provided on the generator 6, and a transmission crown tooth 481 is provided on one side of the transmission magnetic sleeve 48. A drive guide wheel 61 is also provided at the end of the input shaft of the generator 6. A return spring 482 is clamped between the transmission magnetic sleeve 48 and the drive guide wheel 61, and the drive guide wheel 61 is arranged to be tangentially in contact with the side wall of the bridge guide rail 11;

[0048] The reciprocating screw 46 is rotatably connected to the outer wall of the box body 32, and a slide 47 is rotatably connected between the two groups of first slide rods 42. The slide 47 is provided with a nut seat 473 matching the reciprocating screw 46. The bottom of the reciprocating screw 46 is fixed with a driven gear 461 meshing with the transmission crown gear 481. Two groups of symmetrically arranged sliders 471 are also fixed on the slide 47. The outer wall of the box body 32 is provided with a slide groove 322 matching the slider 471. The slide 47 is slidably connected to the outer wall of the box body 32 along the vertical direction through the slide groove 322 and the slider 471.

[0049] Furthermore, the return spring 482 has an elastic force to drive the transmission crown tooth 481 away from the driven gear 461 , and the electromagnetic ring 63 has a magnetic repulsive force on the transmission magnetic sleeve 48 when powered, and the driven gear 461 is meshed with the transmission crown tooth 481 .

[0050] When the hoist bridge car 2 moves up and down in the mine 1 along the bridge car guide rail 11, the friction of the bridge car guide rail 11 on the drive guide wheel 61 is used to drive the generator 6 to rotate and generate electricity, and the electrical energy is stored in the backup battery 5 through the rectifier, providing emergency backup power for the intercom device 3 in the event of a power outage, maintaining the continuity and stability of the alarm intercom. Since the box 32 is arranged between the hoist bridge car 2 and the mine 1, when the backup battery 5 spontaneously combusts, it will not endanger the safety of the miners in the hoist bridge car 2, further improving the safety of use.

[0051] When the number of users of the elevator bridge car 2 collected by the camera module 314 reaches the design threshold, the control electromagnetic ring 63 is energized to generate a magnetic repulsion force on the transmission magnetic sleeve 48, so that the transmission magnetic sleeve 48 overcomes the elastic force of the reset spring 482 and approaches the driven gear 461. At this time, the driven gear 461 is engaged with the transmission crown gear 481. During the operation of the bridge car, the bridge car guide rail 11 is used to drive the driving guide wheel 61 to rotate, and then drive the transmission crown gear 481, the driven gear 461 and the reciprocating screw 46 to rotate, and drive the slide 47 to move up and down along the slide groove 322, and cooperate with the main rod 41 and the second slide rod 43 to realize the coal ash and dust cleaning action of the dust cleaning roller 45 on the surface of the panel 31.

[0052] It should be noted that the driving guide wheel 61 is connected to the input shaft end of the generator 6 through a ratchet structure for unidirectional rotation. When the hoist bridge car 2 moves up, the driving guide wheel 61 does not transmit to the generator 6. When the hoist bridge car 2 moves down, the driving guide wheel 61 transmits to the generator 6, thereby avoiding increasing the upward resistance of the hoist bridge car 2 when the hoist bridge car 2 moves up. When the hoist bridge car 2 moves down, the gravity of the hoist bridge car 2 and the miners is used to drive the driving guide wheel 61 and the generator 6 to generate electricity, effectively reducing the energy loss.

[0053] For further information, see Figure 6-8 , an air inlet 321 is provided on the side of the box body 32 away from the panel 31, and a cooling fan 324 is fixed to the inner wall of the box body 32 on one side of the air inlet 321, and a dust filter is clamped between the air inlet 321 and the cooling fan 324 to further prevent coal dust from invading the internal circuit board, and an air outlet 325 is provided on the side of the box body 32 opposite to the panel 31, and a shovel tooth 472 corresponding to the air inlet 321 is fixed on the side of the slide 47 opposite to the box body 32. The bottom of the panel 31 is rotatably connected to the port side of the box body 32 through a rotating shaft, and an electrical compartment 34 is also provided on the side opposite to the panel 31 and the box body 32, and a control board 9 is encapsulated in the electrical compartment 34. It should be noted that the control board 9 is provided with a 5G communication module and a wireless communication module, and the electrical compartment 34 is provided with two groups of symmetrically arranged first heat dissipation fins 342 on the side opposite to the box body 32.

[0054] When the panel 31 and the box body 32 are aligned, the cooling fan 324 draws air in from the mine 1 through the air inlet 321 and discharges it through the air outlet 325 , thereby performing air exchange inside the box body 32 and achieving the purpose of heat dissipation.

[0055] Since the air inlet 321 is the air intake side, coal ash impurities in the mine air will be adsorbed on the outside of the air inlet 321, causing blockage. When the cleaning mechanism 4 performs the cleaning operation, it also drives the slide 47 to move up and down, and then uses the shovel teeth 472 to remove the coal ash impurities blocking the air inlet 321, thereby maintaining the long-term patency of the air inlet 321.

[0056] Further, please refer to Figure 10-11 , the bottom side of the panel 31 is provided with a liquid supply table 33, the top of the liquid supply table 33 is provided with a matching slot 331 matched with the dust cleaning roller 45, the liquid supply table 33 is provided with a liquid distribution bin 332, and the liquid distribution bin 332 is communicated with the matching slot 331 through a uniform distribution hole 333;

[0057] The electrical bin 34 is provided with a liquid storage tank 7 away from the side of the panel 31, the liquid storage tank 7 is filled with cleaning agent, one side of the liquid storage tank 7 is provided with a plug-in slot 72, the electrical bin 34 is provided with a plug-in rail 341 matched with the plug-in slot 72, the output end of the liquid storage tank 7 is provided with a second electromagnetic valve 73, and the output end of the second electromagnetic valve 73 is communicated with the liquid distribution bin 332 through a conduit 74;

[0058] When the camera module 314 collects the number of users of the elevator bridge compartment 2 reaching the design threshold, the control electromagnetic ring 63 is powered on at the same time, the second electromagnetic valve 73 is powered on, the liquid distribution bin 332 is filled with cleaning agent through the conduit 74, the cleaning agent in the liquid distribution bin 332 is evenly overflowed into the matching slot 331 through the uniform distribution hole 333, so that the dust cleaning roller 45 can absorb the cleaning agent in the matching slot 331 in advance during the cleaning operation, and the miner contact part on the surface of the panel 31 is disinfected at the same time.

[0059] It should be noted that the cleaning agent used in this embodiment is a volatile organic solvent containing 60% to 70% alcohol. Its cleaning principle is to use the good solubility of organic solvents to dust, coal ash and other stains. When the cleaning agent is applied or sprayed to the surface of the contaminated panel 31, the organic solvent dissolves the coal ash and other stains, and then relies on its own rapid evaporation characteristics to completely evaporate in a short time, so that it is not necessary to rinse with clean water, and there is no cleaning agent residue left on the surface of the object, thereby effectively avoiding the phenomenon that coal ash accumulates from the gap of the panel 31 and enters the internal circuit board, causing circuit failure.

[0060] Further, please refer to Figure 11-12 , the bottom of the liquid supply table 33 is also provided with a pressure sensor 335, and the bottom of the liquid distribution bin 332 is also communicated with a first electromagnetic valve 334. The miners in the elevator bridge compartment 2 can use the elbow to press the pressure sensor 335, and open the second electromagnetic valve 73 and the first electromagnetic valve 334 through the pressure sensor 335, so as to provide the miners with cleaning agent, and facilitate the miners to operate the panel 31 in advance to perform hand cleaning operation, and further avoid the damage of coal ash to the circuit.

[0061] Since the panel 31 is rotationally connected to the box body 32 through the rotating shaft, the panel 31 can be turned outward to expose the liquid storage tank 7, so that the maintenance personnel can remove the liquid storage tank 7 from the plug-in rail 341 and replace the liquid storage tank 7, thereby improving the maintenance convenience.

[0062] Further, please refer to Figure 13-14 Both sides of the panel 31 are provided with a cleaning groove 316 that cooperates with the connecting rod 431. The output end of the cooling fan 324 is arranged opposite to the cleaning groove 316. A guide bar 8 is also fixed on one side of the groove of the cleaning groove 316. The guide bar 8 is a rubber strip structure with an L-shaped cross-section. A second heat dissipation fin 71 is also provided on the side of the liquid storage tank 7 away from the electrical compartment 34. The overall cross-section of the second heat dissipation fin 71 and the first heat dissipation fin 342 is arc-shaped.

[0063] Since the control board 9 is encapsulated in the electrical compartment 34, the operating temperature in the electrical compartment 34 can be transferred to the box body 32 through the first heat dissipation fin 342. At the same time, the liquid storage tank 7 storing the detergent is attached to the electrical compartment 34, and can use the detergent stored in the liquid storage tank 7 to absorb heat and transfer it to the box body 32 through the second heat dissipation fin 71. Since the air temperature in the box body 32 is relatively high, the air in the box body 32 can be discharged from the air outlet 325 by the heat dissipation fan 324. At the same time, since the overall cross-section of the second heat dissipation fin 71 and the first heat dissipation fin 342 is in an arc shape, it is convenient to dissipate the hot air in the box body 32. The air is introduced into the air outlet 325, which further improves the heat dissipation efficiency inside the box 32. During the discharge process, when the panel 31 surface has just been coated with a detergent, the hot air discharged from the air outlet 325 is guided by the guide bar 8 and blown into the surface of the panel 31, which can accelerate the rapid drying and volatilization of the detergent, so that the miners can use it quickly after the coal ash is cleaned. At the same time, the air discharged from the air outlet 325 can form a protective wind layer on the surface of the panel 31, further avoiding the adhesion of coal powder to the surface of the panel 31, maintaining the operational visibility of the panel 31, and avoiding misoperation underground.

[0064] The present invention uses a panel 31 with a liquid storage tank 7 and a box body 32 with a cleaning mechanism 4. During the operation of the elevator bridge car 2, the gravitational potential energy of the downward movement of the elevator bridge car 2 can be used to store electrical energy for the backup battery 5, and at the same time, the cleaning mechanism 4 can be driven to operate to clean the surface of the intercom device 3 from coal ash. This can improve the circuit safety of the intercom device 3 in a dusty environment in a mine, has high heat dissipation efficiency, has market prospects, and is suitable for promotion and application.

[0065] The above is only the best implementation method adopted by this application in combination with current actual needs, but the scope of protection of this application is not limited to this.
