Description

Technical Field

[0001] The present invention relates to the technical field of mine environment monitoring, and more specifically, to a comprehensive mine environment monitoring terminal. Background Art

[0002] With the continuous development of mine production operations and the increasing requirements for safety management, the importance of comprehensive mine environment monitoring terminals in mine safety production has become increasingly prominent. Existing mine monitoring terminal devices, especially monitoring systems used in complex mine environments, although can meet the daily monitoring needs to a certain extent, still have many technical and usage problems, which limit their performance and reliability in practical applications.

[0003] First of all, the disassembly, installation and maintenance of existing mine monitoring terminals are not convenient enough. Due to the complex mine environment, the equipment maintenance cycle is long and the working conditions are poor. The disassembly, installation and maintenance of existing equipment usually require professional personnel to perform cumbersome operations. Most traditional monitoring systems adopt fixed installation methods, and the connections between components are relatively complex. This not only increases the difficulty of equipment maintenance, but also takes a long time to repair in case of failure, affecting the safety and efficiency of mine production.

[0004] Secondly, the accuracy of data detection is also a major pain point of existing mine monitoring terminals. In mine operations, the data acquisition functions of monitoring terminals are very important, especially the monitoring of environmental parameters such as temperature, humidity, and gas concentration. However, the sensor accuracy and data transmission stability of existing equipment often cannot meet the strict safety monitoring requirements, resulting in inaccurate or delayed collected data, making it difficult for on-site staff to obtain accurate environmental data in a timely manner, further increasing the risks of mine operations.

[0005] In addition, existing mine monitoring terminals generally have poor heat dissipation effects. Monitoring equipment in mines is usually in a harsh environment of high temperature and high humidity. Excessive temperature inside the equipment will cause overheating of components, thus affecting the stability and service life of the equipment. The heat dissipation design of existing monitoring terminals is usually not scientific enough to effectively ensure the stability of the equipment during long-term high-load operation, resulting in the equipment overheating and shutting down, affecting the continuous operation of the monitoring system.

[0006] Finally, the monitoring range of existing monitoring equipment is limited and cannot effectively cover all corners of the mine interior. The interior space of the mine is narrow and complex. Traditional cameras often cannot provide an all-round monitoring perspective, resulting in monitoring blind spots in some areas, increasing potential safety hazards. Although some monitoring equipment has certain adjustment functions, due to the design limitations of the equipment itself, the adjustment of the rotation angle and pitch angle is not precise enough, and the monitoring angle cannot be flexibly adjusted, resulting in a limited monitoring range of the on-site picture.

[0007] Therefore, the existing mine environment comprehensive monitoring terminal urgently needs a design scheme with a more reasonable structure and more complete functions to solve the problems of inconvenient disassembly and maintenance, low data detection accuracy, insufficient heat dissipation and limited monitoring range in the existing technology, and improve the reliability and real-time performance of mine safety management.

[0034] The beneficial effects of the present invention: 1. Facilitating disassembly, assembly and maintenance, the installation cover in this patent solution adopts a modular structure design. By combining the connection operation, assembly cover, assembly column, upper protective cover and lower protective cover, a complete installation cover structure is formed, which is convenient for disassembling, assembling and maintaining the installation cover and its components. This design not only greatly shortens the time for maintenance and fault repair, but also improves the convenience of equipment maintenance. The quick disassembly, assembly and flexible adjustment of the equipment enable maintenance personnel to quickly replace damaged components, avoid downtime caused by faults, and improve the continuity and safety of mine operations.

[0035] 2. Ensuring the accuracy of data detection, the dust cleaning component is placed in the storage tank to block the connection position between the air supply chamber and the dust exhaust chamber, preventing the dust remaining in the dust exhaust chamber from being sucked into the air supply chamber together with the external air under negative pressure and interfering with the monitoring unit. The dust cleaning component can effectively clean the detection surface of the monitoring unit to improve the accuracy of data detection.

The upper protective cover is made of metal material, which can ensure that the heat generated during the operation of each power component can be transmitted outward through the internal heat dissipation fins, the upper protective cover and the external heat dissipation fins. The air discharged from the upper ventilation port during the monitoring operation can fully contact the external heat dissipation fins for heat dissipation, so as to achieve efficient heat dissipation of the equipment, prevent faults or performance degradation caused by overheating, significantly improve the stability and service life of the monitoring terminal, and ensure the efficiency and reliability of the mine safety monitoring system.

[0037] 4. Expanding the monitoring range of the on-site picture. Through the design of the corner adjustment component and the pitch adjustment component in this solution, the monitoring camera can achieve flexible and precise rotation and angle adjustment, thus expanding the monitoring range of the camera. The camera can not only rotate widely in the horizontal direction, but also be precisely adjusted in the vertical direction, eliminating the problem of limited viewing angle of traditional monitoring equipment, ensuring that all areas inside the mine can be effectively covered, guaranteeing the comprehensiveness and accuracy of mine safety monitoring, and reducing potential safety hazards.

[0038] In summary, by optimizing the design of the comprehensive monitoring terminal for the mine environment, this solution enhances the convenience of equipment maintenance, improves the accuracy of data detection, ensures the long-term stable operation of the equipment in the complex mine environment, expands the monitoring range at the same time, and enhances the comprehensiveness and safety of on-site monitoring.

Detailed implementation mode

[0041] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0042] Embodiment 1 Please refer to Figure 1 , Figure 2 , Figure 4 , a comprehensive monitoring terminal for mine environment, including a mounting cover 1. An air supply chamber 11 and a dust exhaust chamber are provided in the mounting cover 1. An upper ventilation opening 111 and a lower ventilation opening 112 that are in communication with the external environment are respectively provided at the top and bottom of the air supply chamber 11. A storage groove 121 that is in communication with the air supply chamber 11 is opened at the top end of the dust exhaust chamber, and the bottom end of the dust exhaust chamber is in communication with the external environment.

[0043] It also includes a plurality of monitoring units 2 which are installed in the air supply cavity 11 and distributed along the diameter direction of the mounting cover 1 , and the detection surfaces of the monitoring units 2 are all arranged toward the air supply cavity 11 .

[0044] It also includes a fan impeller 3, a cleaning component 4 and a driving component 5. The fan impeller 3 is rotatably installed in the air supply chamber 11 and rotates around the axis of the installation cover body 1. The cleaning component 4 includes a lifting bracket 41, a mounting ring 42 and cleaning cotton 43 fixed to the inner wall of the mounting ring 42 in a ring-shaped arrangement. The lifting bracket 41 is nested and installed in the storage groove 121 and moves up and down along the axis of the installation cover body 1. The mounting ring 42 is rotatably installed in the lifting bracket 41 and rotates around the axis of the installation cover body 1. The cleaning cotton 43 is fully in contact with the detection surface of each group of monitoring units 2 when driven by the lifting bracket 41 to move up and down. When the lifting bracket 41, the mounting ring 42 and the cleaning surface are in the storage groove 121, the connecting part of the dust exhaust chamber and the air supply chamber 11 is blocked. The driving component 5 maintains power connection with the fan impeller 3, the lifting bracket 41 and the mounting ring 42.

[0045] It also includes a monitoring camera 6 and an angle adjustment component 7 and a pitch adjustment component 8 which are transmission-connected to the monitoring camera 6. The monitoring camera 6 is assembled at the bottom of the mounting cover 1 and arranged outside the air supply cavity 11 and the air exhaust cavity 12.

[0046] The setting of the mounting cover 1 can form an air supply chamber 11 and a dust exhaust chamber inside it, and ensure that the various components involved are stably installed at their corresponding positions, so as to provide a stable space environment for the installation, operation and environmental monitoring of the equipment.

[0047] The monitoring unit 2 uses various sensors for detecting parameters related to the mine environment, including temperature sensors, humidity sensors, dust concentration sensors, gas concentration sensors and other types of toxic and hazardous substance detection sensors, to monitor relevant data of the mine environment in real time.

[0048] When the fan impeller 3 is driven by the driving component 5, it can rotate clockwise or counterclockwise around its own axis. When the mine environment is normally monitored, the fan impeller 3 is controlled to rotate forward to input the external ambient air into the air supply chamber 11 from the lower vent 112, and the air is discharged from the upper vent 111 after each group of monitoring units 2 completes the detection of relevant data. In this process, since the lifting bracket 41, mounting ring 42, and cleaning cotton 43 in the cleaning component 4 are in the storage groove 121 to block the connection position between the air supply chamber 11 and the dust exhaust chamber, it can effectively prevent the dust remaining in the dust exhaust chamber under the action of negative pressure from being sucked into the air supply chamber 11 together with the external air, thereby avoiding interference caused by each monitoring unit 2 to effectively improve the accuracy of data detection.

[0049] When the driving component 5 drives the fan impeller 3 to rotate in the reverse direction and drives the dust cleaning component 4 to operate, the fan impeller 3 can draw external air into the air supply chamber 11 from the upper ventilation opening 111. At the same time, the lifting bracket 41 drives the mounting ring 42 and the cleaning cotton 43 to reciprocate up and down within the stroke range. The mounting ring 42 also drives the cleaning cotton 43 to continuously rotate, and the cleaning cotton 43 fully cleans the detection surfaces of each monitoring unit 2. The cleaned dust can enter the dust discharge chamber under the action of the downward blowing air and its own gravity, and the dust in the dust discharge chamber is discharged to the outside under the continuous action of the downward blowing air. It can fully clean the detection surfaces of each monitoring unit 2 to further improve the accuracy of data detection.

[0050] By installing a monitoring camera 6, the surrounding environment of the equipment and the activity status of personnel can be monitored in real time, and the rotation attitude and pitch attitude of the camera can be adjusted in cooperation with the corner adjustment component 7 and the pitch adjustment component 8 to increase the monitoring range of the monitoring camera 6, and the monitoring camera 6 can also track and monitor specific areas or personnel.

The guiding seat 412 is slidably installed in the lifting groove 156. An annular sunk groove 413 is formed in the assembly ring 411. A driving bevel gear B421 arranged in the annular sunk groove 413 is fixedly connected to the bottom of the mounting ring 42.

[0067] The dust cleaning assembly 4 includes a plurality of groups of spline shafts 44, reciprocating lead screws 45, and transmission shafts 46 distributed in a circular array. The spline shafts 44 and the reciprocating lead screws 45 are both rotatably installed in the lifting groove 156. The transmission shaft 46 is rotatably installed in the guiding seat 412 and is arranged radially. A driving bevel gear C414 slidably inserted and connected to the spline shaft 44 is rotatably installed on the guiding seat 412.

The synchronous pulley 442 and the driving bevel gear D444 are both arranged in the upper protective cover 16. The driving assembly 5 is power-connected to the driving bevel gear D444.

[0069] The combination of the lifting groove 156 and the guiding seat 412 can ensure that the lifting bracket 41 stably moves up and down along the vertical direction around the assembly column 15, and can ensure that the spline shaft 44 and the reciprocating lead screw 45 are stably assembled in the lifting groove 156 along the vertical direction.

[0070] When the driving assembly 5 drives the driving bevel gear D444 to operate, it can drive each group of spline shafts 44 and reciprocating lead screws 45 to operate stably through the combination of the synchronous pulley 442, the synchronous belt 443, and the driving spur gears A441 and B451.

[0071] During the synchronous operation of each group of reciprocating lead screws 45, it can drive the lifting bracket 41 to perform reciprocating up and down movement along the vertical direction, and then drive the mounting ring 42 and the cleaning cotton 43 to perform synchronous up and down movement. During the up and down movement of the lifting bracket 41, the driving bevel gear C414 assembled in the guiding seat 412 always maintains power connection with the vertically arranged spline shaft 44. During the synchronous operation of each group of spline shafts 44, it can drive each group of transmission shafts 46 to operate stably through the combination of the driving bevel gear C414 and the transmission bevel gear, and then drive the mounting ring 42 and the cleaning cotton 43 to operate stably through the combination of the driving bevel gear B461 and the transmission bevel gear B421.

[0072] During the reciprocating up and down movement and continuous rotation of the cleaning cotton 43, it can fully clean the detection surface of the monitoring unit 2 installed on the assembly column 15.

[0073] To ensure that the driving assembly 5 can achieve power connection with the driving bevel gear A32 and the driving bevel gear D444, and ensure that the operating attitude of the driving assembly 5 can achieve normal detection of the mine environment and the cleaning function of the monitoring unit 2, the following technical solutions are provided.

[0074] The driving assembly 5 includes a driving motor 51, a driving shaft A52, a driving shaft B53, and a ratchet mechanism. The driving motor 51 is fixedly installed on the connecting ring seat 13 and arranged in the upper protective cover 16. The output shaft of the driving motor 51 is power-connected to the driving shaft A52. A driving bevel gear A521 that meshes with the driving bevel gear A32 is fixedly connected to the driving shaft A52.

[0075] A drive shaft A52 is fixedly connected with a transmission spur gear C522. A transmission spur gear D543 that meshes with the transmission spur gear C522 is fixedly connected to the outer periphery of an inner ratchet wheel 541 of a ratchet mechanism. A pawl 542 of the ratchet mechanism is rotatably mounted on the outer periphery of a drive shaft B53 and cooperates with the inner ratchet wheel 541. A drive bevel gear D531 that meshes with a transmission bevel gear D444 is fixedly connected to the drive shaft B53.

[0076] A drive motor 51 is directly power-connected to a drive bevel gear A521 through the drive shaft A52, and can drive a fan impeller 3 to operate stably through the combination of the drive bevel gear A521 and the transmission bevel gears in both the forward and reverse rotation states of the drive motor 51.

[0077] A reed 532 that abuts against the pawl 542 is further assembled on the outer periphery of the drive shaft B53. The reed 532 can apply an outward-opening acting force to the pawl 542, so that the pawl 542 remains meshed with the ratchet teeth on the inner ratchet wheel 541. When the drive motor 51 rotates forward, the inner ratchet wheel 541 and the pawl 542 are in a slipping state, and power cannot be transmitted to the drive shaft B53 through the ratchet mechanism.

[0078] When the drive motor 51 rotates in reverse, the inner ratchet wheel 541 is driven to operate stably through the combination of the transmission spur gear C522 and the transmission spur gear D543. Further, the inner ratchet wheel 541 drives the pawl 542 and the drive shaft B53 to operate stably, and a dust cleaning component 4 is driven to operate stably through the combination of the drive bevel gear D531 and the transmission bevel gear D444.

[0079] Embodiment 4 Please refer to Figure 4 、 Figure 6 、 Figures 11 - 13 to ensure that the corner adjustment component 7 can be stably installed in the mounting cover 1 and effectively adjust the rotation angle of the monitoring camera 6. The following technical solutions are provided for this.

[0080] The corner adjustment component 7 includes an installation sleeve 71 and an adjustment motor A72. The installation sleeve 71 is rotatably installed at the axis center of an assembly column 15. Two groups of ear seats 711 are fixedly connected to the bottom end of the assembly column 15. The monitoring camera 6 is rotatably installed on the ear seats 711 and rotates around a horizontal axis. The adjustment motor A72 is fixedly installed on the top of a connection cover 155 and is arranged in an upper protective cover 16. A transmission bevel gear E712 is fixedly connected to the top end of the installation sleeve 71. The transmission bevel gear E712 is arranged above the connection cover 155. A drive bevel gear E721 that meshes with the transmission bevel gear E712 is fixedly connected to the output shaft of the adjustment motor A72.

[0081] By means of the arrangement of the mounting sleeve 71, it can be ensured that the adjustment motor A72 arranged in the upper mounting cover can be in power connection with the monitoring camera 6 arranged in the lower protective cover 17. When the adjustment motor A72 operates, the combination of the driving bevel gear E721 and the transmission bevel gear E712 drives the mounting sleeve 71 and the monitoring camera 6 to rotate stably around the vertical axis, realizing precise adjustment of the rotation angle of the monitoring camera 6.

[0082] To ensure the stable installation of the pitch adjustment assembly 8 and realize the effective adjustment of the pitch angle of the monitoring camera 6, the following technical solutions are provided.

[0083] The pitch adjustment assembly 8 includes an adjustment motor B81, a lifting shaft 82 and a connecting shaft 83 arranged in the mounting sleeve 71. The adjustment motor B81 is fixedly installed above the connecting cover 155 and arranged in the upper protective cover 16. The connecting shaft 83 is rotatably installed at the bottom of the lifting shaft 82. The bottom end of the connecting shaft 83 is hinged to the monitoring camera 6 through a connecting rod 831. The adjustment motor B81 is in power connection with a driving gear 811. A vertically arranged strip-shaped through groove 821 is opened at the top end of the lifting shaft 82, and a transmission rack 822 engaged with the driving gear 811 is fixedly connected in the strip-shaped through groove 821.

[0084] To ensure that the lifting shaft 82 can lift and lower stably in the vertical direction, a vertically arranged guide rod 163 is fixedly connected in the upper protective cover 16, and a guide groove 823 that is slidably inserted with the guide rod 163 is opened on the top side wall of the lifting shaft 82. When the adjustment motor B81 drives the driving gear 811 to operate, it can drive the transmission rack 822 and the lifting shaft 82 to lift and lower stably along the guide rod 163, and the strip-shaped through groove 821 provided at the top end of the lifting shaft 82 can ensure the stable installation of the driving gear 811 therein.

[0085] The connecting shaft 83 is rotatably installed at the bottom of the lifting shaft 82 in a relatively rotatable manner and can lift and lower synchronously with the lifting shaft 82. Furthermore, it drives the monitoring camera 6 to adjust the pitch angle through the connecting rod 831. When the monitoring camera 6 is rotated and adjusted by the rotation angle adjustment assembly 7, it can drive the connecting shaft 83 to rotate synchronously under the action of the connecting rod 831, so that the monitoring camera 6 can adjust the pitch angle through the lifting and lowering connecting shaft 83 in any rotation angle posture.

[0086] To ensure that the adjustment motor B81 can drive the gear 811 to operate stably and realize the stable adjustment of the lifting posture of the lifting shaft 82, the following technical solutions are provided.

[0087] A worm 812 is fixedly connected to the output shaft of the adjustment motor B81, and a worm gear 813 that cooperates with the worm 812 is coaxially fixedly connected to the driving gear 811.

[0088] The worm 812 and the worm gear 813 are both rotatably installed above the connecting cover 155, and the combination of the two has the characteristics of speed reduction, torque increase and one-way self-locking. When the power of the adjusting motor B81 is transmitted through the worm 812 and the worm gear 813, speed reduction and torque increase can be achieved, so as to drive the transmission rack 822 and the lifting shaft 82 to stably lift and lower in the vertical direction through the driving gear 811.

[0089] At the same time, the power can only be transmitted unidirectionally from the worm 812 to the worm gear 813. When the adjusting motor B81 is in a stopped state, the worm gear 813 and the driving gear 811 are locked and positioned by the stationary worm 812, which can prevent the monitoring camera 6, the lifting shaft 82 and the connecting shaft 83 from falling under their own gravity, affecting the accuracy of the adjustment of the pitching angle of the monitoring camera 6.
