Description

[0002] In the mine operation environment, elevators play a vital role. They are used to transport miners, equipment and various materials. They are key facilities to ensure efficient and safe vertical transportation in mines. The bridge compartment wireless alarm intercom device is a device that integrates wireless communication technology and alarm system, aiming to improve the safety of the bridge compartment and the miners' experience. The device can provide real-time communication with the outside world in an emergency, ensuring that miners can get help in time when encountering a fault. It is usually integrated with the buttons of the bridge compartment.

[0003] However, the existing mine elevator intercom system has many problems that need to be solved: The underground environment of mines is complex and harsh, usually with high temperatures and large amounts of dust. Traditional elevator intercom equipment is often designed based on ordinary ground environments. In such a mine environment, coal ash in the air or on the hands of miners is likely to stay on the operation panel when operating the buttons. The long-term accumulation of ash invades the control circuit, causing dust intrusion into electronic components and short circuits, resulting in component failures, which seriously affects the stability and service life of the intercom system. At the same time, coal ash contaminates the operation panel and blocks operation information, which also reduces the accuracy of operation.

DETAILED DESCRIPTION

[0017] The embodiments will be combined with the drawings in the specification to clearly and completely describe the technical solution of the present application. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without making any creative work shall fall within the scope of protection of the present application.

[0018] Embodiment 1: 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 matching the elevator bridge car 2, and 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, and the panel 31 is kept 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, and the touch screen 312 is used for touch operation and emergency video call function. The top is provided 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 line of sight of the lens. The camera module 314 cooperates 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 provided with integrated voice recognition technology, and multi-language options are added to the device software, supporting English and local major languages, and using natural language processing (NLP) technology to ensure smooth switching between different languages ​​for barrier-free communication between miners and rescuers; The sensor module 313 integrates an infrared sensor and a smoke sensor to automatically identify the fire status in the bridge compartment. For example, if a mining lamp battery or other high-risk items spontaneously combusts 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.

[0019] The intercom module 315 uses a high-sensitivity microphone and a high-fidelity speaker, and integrates active noise cancellation technology to filter out ambient noise and improve communication clarity in emergency situations.

[0020] 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 with 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 approach each other. The opposite ends of the first slide rod 42 and the second slide rod 43 are both rotatably connected with rollers 411 to reduce sliding friction. A connecting rod 431 is fixed at the end of the second slide rod 43 away from the main rod 41. A dust cleaning roller 45 is rotatably connected between the two groups of second slide rods 43. A driving mechanism for driving the main rod 41 to rotate back and forth at equal angles is provided at the bottom of the box body 32.

[0021] 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 clean and wipe 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 of the coal ash dust adhered to the surface of the panel 31.

[0022] See also Figure 3-6 It should be noted that, in this embodiment, the driving mechanism includes a transmission magnetic sleeve 48 and a reciprocating screw 46, a generator 6 is fixed at the bottom of the box 32, 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, 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, a transmission crown tooth 481 is provided on one side of the transmission magnetic sleeve 48, a driving guide wheel 61 is also provided at the end of the input shaft of the generator 6, a reset spring 482 is clamped between the transmission magnetic sleeve 48 and the driving guide wheel 61, and the driving guide wheel 61 is arranged to be tangent to the side wall of the bridge compartment guide rail 11; 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 bars 42. The slide 47 is provided with a nut seat 473 matching the reciprocating screw 46, and a driven gear 461 meshing with the transmission crown gear 481 is fixed to the bottom of the reciprocating screw 46. Two groups of symmetrically arranged slide blocks 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 slide block 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 slide block 471. 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 .

[0023] 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 driving guide wheel 61 is used to drive the generator 6 to rotate and generate electricity, and the electric 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, thereby further improving the safety of use.

[0024] When the number of users of the elevator bridge car 2 collected by the camera module 314 reaches the designed threshold, the control electromagnetic ring 63 is energized to generate magnetic repulsion 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 meshed 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, thereby driving the transmission crown gear 481, the driven gear 461 and the reciprocating screw 46 to rotate, and driving the slide 47 to move back and forth 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.

[0025] It should be noted that the driving guide wheel 61 is connected to the end of the input shaft 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 power to the generator 6. When the hoist bridge car 2 moves down, the driving guide wheel 61 transmits power 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.

[0026] 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, a cooling fan 324 is fixed to the inner wall of the box body 32 on one side of the air inlet 321, a dust filter is clamped between the air inlet 321 and the cooling fan 324 to further prevent coal ash from invading the internal circuit board, an air outlet 325 is provided on the side of the box body 32 opposite to the panel 31, 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, an electrical compartment 34 is also provided on the side of the panel 31 opposite to the box body 32, and a control board 9 is encapsulated in the electrical compartment 34. It should be noted that a 5G communication module and a wireless communication module are provided on the control board 9, and two groups of symmetrically arranged first cooling fins 342 are provided on the side of the electrical compartment 34 opposite to the box body 32.

[0027] When the panel 31 and the box body 32 are aligned, the cooling fan 324 is used to suck air in the mine 1 from the air inlet 321 and discharge it through the air outlet 325, so as to exchange air inside the box body 32 and achieve the purpose of heat dissipation.

[0028] 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 to cause 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.

[0029] For further information, see Figure 10-11 A liquid supply platform 33 is provided on one side of the bottom of the panel 31, a matching groove 331 matching with the dust cleaning roller 45 is provided on the top of the liquid supply platform 33, a liquid separation chamber 332 is provided in the liquid supply platform 33, and the liquid separation chamber 332 is connected with the matching groove 331 through an equal distribution hole 333; A liquid storage tank 7 is provided on one side of the electrical compartment 34 away from the panel 31. The liquid storage tank 7 is filled with a cleaning agent. A plug-in slot 72 is provided on one side of the liquid storage tank 7. A plug-in rail 341 matching the plug-in slot 72 is provided on the electrical compartment 34. A second solenoid valve 73 is provided at the output end of the liquid storage tank 7. The output end of the second solenoid valve 73 is connected to the liquid separation compartment 332 through a conduit 74. When the number of users of the hoist bridge car 2 collected by the camera module 314 reaches the designed threshold, the electromagnetic ring 63 is controlled to be energized and the second electromagnetic valve 73 is controlled to be energized at the same time, and the cleaning agent is filled into the liquid separation chamber 332 through the conduit 74. The cleaning agent in the liquid separation chamber 332 overflows evenly into the matching groove 331 through the equalizing hole 333, so that the dust cleaning roller 45 can absorb the cleaning agent in the matching groove 331 in advance during the cleaning operation, and disinfect the parts of the panel 31 that are in contact with miners while cleaning.

[0030] It should be noted that the cleaning agent used in this embodiment is a volatile organic solvent containing 60% to 70% alcohol. The cleaning principle is to use the good solubility of organic solvents for stains such as dust and soot. When the cleaning agent is applied or sprayed on the surface of the contaminated panel 31, the organic solvent dissolves the soot and other stains, and then relies on its own rapid volatilization characteristics to completely evaporate in a short time, so there is no need to rinse with clean water, and no cleaning agent residue will be left on the surface of the object, thereby effectively preventing the soot from accumulating from the gaps in the panel 31 and entering the internal circuit board, causing circuit failure.

[0031] For further information, see Figure 11-12 A pressure sensor 335 is also provided at the bottom of the liquid supply platform 33, and a first solenoid valve 334 is also connected to the bottom of the liquid separation chamber 332. The miners in the hoist bridge compartment 2 can use their elbows to pressurize the pressure sensor 335, and open the second solenoid valve 73 and the first solenoid valve 334 through the pressure sensor 335 to provide cleaning agent for the miners, so that the miners can clean their hands in advance before operating the panel 31, further avoiding the damage of coal ash to the circuit.

[0032] Since the panel 31 is rotatably connected to the box body 32 via a rotating shaft, the panel 31 can be turned outward to expose the liquid storage tank 7, thereby facilitating maintenance personnel to remove the liquid storage tank 7 from the docking rail 341 and replace the liquid storage tank 7, thereby improving maintenance convenience.

[0033] For further information, see Figure 13-14Both sides of the panel 31 are provided with cleaning grooves 316 that cooperate with the connecting rod 431, and 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 cooling 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 cooling fin 71 and the first cooling fin 342 is arc-shaped.

[0034] 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 the detergent stored in the liquid storage tank 7 can be used 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 surface of the panel 31 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.

[0035] 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 box 2, the gravitational potential energy of the downward movement of the elevator bridge box 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 coal ash on the surface of the intercom device 3. The safety of the circuit use of the intercom device 3 in a dusty environment in a mine can be improved, the heat dissipation efficiency is high, the market prospects are good, and it is suitable for promotion and application.

[0036] The above is only the best implementation method adopted by this application in combination with current actual needs, but the protection scope of this application is not limited to this.
