Description

Technical Field

[0001] The present invention relates to the technical field of tunnel safety detection, and in particular to an embedded integrated tunnel safety detection device based on the application of unmanned aerial vehicles. Background Art

[0002] To improve coal mine tunnel safety, replacing manual inspections with drones is becoming a growing trend. While drone technology has been used for tunnel inspections in recent years, it has been limited by short flight ranges, unstable signal coverage, and the need for structural modifications to the tunnel required for equipment installation, hindering large-scale adoption.

[0003] Traditional tunnel safety detection relies on split signal relay stations and independent charging devices, which have the following problems:

[0004] 1. Difficulty in receiving satellite signals: Currently, drones have difficulty receiving signals and the signals are unstable when conducting inspections in tunnels.

[0005] 2. Drones cannot maintain effective flight time in tunnels: Currently, subway and railway tunnels are usually more than 1 km long, and unmanned, single-use drone inspections have great difficulty maintaining flight time.

[0006] 3. Large space occupation: Split signal equipment and drone charging equipment need to be installed separately, occupying the space inside the tunnel and affecting vehicle traffic safety;

[0007] 4. Signal interference risk: When the relay station and charging module coexist in close proximity, poor electromagnetic compatibility can easily lead to communication signal attenuation or reduced charging efficiency;

[0008] 5. High maintenance cost: Independent deployment of multiple modules requires frequent maintenance, which results in high labor costs and affects the normal operation of the tunnel.

[0009] 6. The humidity in the tunnel is high, especially in poorly ventilated areas. Moisture will accelerate the corrosion of metal parts and increase the risk of electrical short circuits.

[0010] To address the above problems, an embedded integrated tunnel safety detection device based on UAV application is proposed. Summary of the Invention

[0037] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0038] like Figure 1 - Figure 6 As shown, the present invention provides an embedded integrated tunnel safety detection device based on drone application, including a shell 1 installed at the communication channel of the tunnel side wall, two partition plates 2 are provided inside the shell 1, and the inside of the shell 1 is divided into a signal relay layer 3, a charging layer 4 and a platform layer 5 by the two partition plates 2, and the signal relay layer 3, the charging layer 4 and the platform layer 5 are respectively provided with a signal relay module, a wireless charging module and a drone platform 6, and the shell 1 is also provided with a moisture-proof mechanism 7 and a cleaning mechanism 8 for cleaning the drone platform 6. The moisture-proof mechanism 7 is arranged in the middle of the shell 1 near the tail end of the drone, and the cleaning mechanism 8 is connected to the moisture-proof mechanism 7. The cleaning mechanism 8 faces the drone platform 6, and multiple sealing doors 9 are hinged on one side of the shell 1.

[0039] Electric push rods 64 are installed on both sides of the interior of the housing 1 , and the output ends of the two electric push rods 64 are hinged to the sealing door 9 located on the platform layer 5 .

[0040] By setting a groove as the installation space at the communication channel of the tunnel side wall and reserving a power interface at the rear, the shell 1 is installed in the groove, and the signal relay module, wireless charging module and drone platform 6 are integrated into a single flat shell 1, which is embedded in the tunnel side wall and the outer surface is flush with the wall;

[0041] Among them, the signal relay module supports the Mesh self-organizing network protocol, and a redundant communication network is automatically formed between multiple devices. When a single node fails, the signal switching delay is ≤50ms; a metal shielding layer is set between the relay antenna and the charging coil, and the frequency peak shifting scheduling technology is adopted to avoid signal crosstalk; the wireless charging module adopts directional magnetic resonance coupling technology, with an effective charging distance of 10-15cm, and integrates foreign object detection and temperature monitoring functions. The drone platform 6 and its adjacent sealed door 9 are matched with an electric push rod 64 to realize a retractable drone take-off and landing platform.

[0042] Furthermore, the signal relay module, wireless charging module and UAV platform 6 can be linked to an intelligent control system to achieve communication management, charging management and coordinated scheduling.

[0043] Communication management: Dynamically adjusts relay signal strength based on tunnel topology maps, supporting breakpoint resuming and multi-path redundant transmission;

[0044] Charging management: LiDAR and visual recognition are used to guide the drone to precise docking, real-time monitoring of battery status during charging, and automatic power-off in case of over-temperature or over-voltage.

[0045]  Collaborative dispatching: Multiple devices are networked via the LoRa protocol, and drone patrol inspections are carried out through the dispatch center.

[0046] The embedded installation of the shell 1 and the retractable platform design of the drone platform 6 completely avoid vehicle traffic areas and are suitable for railways, subways and municipal tunnels with narrow boundaries. When conducting safety inspections, the drone receives inspection instructions and flies along a preset path to complete daily tunnel inspections and data collection. When the battery level is less than 20%, it autonomously navigates to the nearest charging station and lands on the deployment platform through laser radar positioning. During charging, the relay station takes over the drone's communication link to ensure continuous data transmission.

[0047] This invention integrates signal relay, drone charging, and docking functions into the housing (1) and employs a tunnel sidewall embedded installation design, enabling long-term autonomous drone inspections with zero spatial interference. The multi-layered module layout with electromagnetic shielding isolation, directional magnetic resonance wireless charging technology, and a dynamic operation and maintenance strategy based on environmental awareness significantly improve tunnel safety inspection efficiency and equipment reliability.

[0048] The moisture-proof mechanism 7 includes a fixed tube 71, a threaded lifting tube 72, a first sleeve 73, a second sleeve 74, two sets of blowing components 75 and a driving component 76 for driving the blowing component 75 to rise and fall. The fixed tube 71 is fixedly arranged on the inner bottom wall of the shell 1 and is located at the tail end of the UAV platform 6. The first sleeve 73 and the second sleeve 74 are fixedly inserted on the two partition plates 2 respectively. The fixed tube 71 is located just below the second sleeve 74. The two ends of the threaded lifting tube 72 are respectively inserted into the inside of the first sleeve 73 and the second sleeve 74, and the threaded lifting tube 72 is inserted into the inside of the first sleeve 73 and the second sleeve 74. The bottom of the downcomer 72 extends into the fixed tube 71. The two sets of blowing assemblies 75 are fixedly arranged on the outer wall of the threaded lifting tube 72, and the two blowing assemblies 75 are respectively located inside the charging layer 4 and the platform layer 5. The driving assembly 76 is installed on the outer wall of the second sleeve 74, and the threaded lifting tube 72 is transmission-connected to the driving assembly 76. An air pump 10 is provided on one side of the shell 1 close to the fixed tube 71. The output end of the air pump 10 passes through the fixed tube 71 and extends to the inside of the fixed tube 71. The input end of the air pump 10 passes through the shell 1 and extends to the outside of the shell 1.

[0049] Since the humidity in the tunnel is high, especially in poorly ventilated areas, moisture will accelerate the corrosion of metal parts and increase the risk of electrical short circuits. Therefore, a moisture-proof mechanism 7 is provided to isolate external moisture and protect the internal working modules from damage. When working, the air pump 10 is started, and the air pump 10 sucks in external air and transports it into the fixed pipe 71. Then the air enters the first sleeve 73 through the threaded lifting pipe 72 and is output from the first sleeve 73 to the signal relay layer 3. Since the threaded lifting pipe 72 is connected to the driving component 76, the driving component 76 can drive the threaded lifting pipe 72. It moves up and down inside the first sleeve 73 and the second sleeve 74, thereby driving the two groups of blowing components 75 outside the threaded lifting tube 72 to rise and fall, and then adjusting the height of the two groups of blowing components 75 so that the two groups of blowing components 75 can move and blow air in the charging layer 4 and the platform layer 5 respectively. This can not only effectively blow away the moisture accumulated in the charging layer 4 and the platform layer 5, and prevent moisture from damaging the electronic components inside these areas, but also use the airflow generated by the blowing to take away the heat generated by work in these areas, thereby achieving a heat dissipation effect and ensuring the stable operation of the entire equipment in the tunnel.

[0050] It is worth noting that the air inside the tunnel has a certain humidity, so a dehumidification device can be set outside the shell 1. By connecting the air pump 10 to the dehumidification device, the air entering the shell 1 is made dry air. This is the existing technology.

[0051] The blowing assembly 75 includes a fixed block 77 and two blowing plates 78 rotatably arranged on both sides of the fixed block 77. The fixed block 77 is fixedly sleeved on the outer wall of the threaded lifting tube 72 and is located above the fixed tube 71. The blowing plates 78 are rotatably connected to the fixed block 77 through a rotating shaft 79. A transmission gear 80 is fixedly sleeved on the rotating shaft 79. Air guide pipes are provided on both sides of the fixed block 77 to respectively connect the fixed tube 71 and the blowing plates 78.

[0052] Two tooth plates 81 are symmetrically provided on both sides of the inner wall of the housing 1 about the threaded lifting tube 72, and one side of the two tooth plates 81 is fixedly connected to the inner wall of the housing 1, and the other side of the tooth plates 81 is meshed with the transmission gear 80;

[0053] When the threaded lifting tube 72 moves up and down, the transmission gear 80 engages with its corresponding tooth plate 81 and then rotates.

[0054] The driving assembly 76 includes a gear ring 82 and a driving member for driving the gear ring 82 to rotate. The gear ring 82 is rotatably set on the top of the second sleeve 74 and is sleeved with the threaded lifting tube 72. The inner wall of the gear ring 82 is fixedly connected to a limiting protrusion 84, and the outer wall of the threaded lifting tube 72 is provided with a threaded groove 85 that is compatible with the limiting protrusion 84.

[0055] When the driving member is activated, it can drive the gear ring 82 to rotate. When the gear ring 82 rotates, due to the spiral fit between the limiting protrusion 84 and the thread groove 85, the threaded lifting tube 72 moves up and down along the axial direction of the second sleeve 74. When the threaded lifting tube 72 is raised or lowered, the transmission gears 80 on the blowing assemblies 75 at both ends thereof move along the tooth plate 81 and rotate. Through the meshing relationship between the transmission gear 80 and the tooth plate 81, the rotating shaft 79 is driven to rotate. The rotation drives the blowing plate 78 to rotate synchronously. Therefore, when the threaded lifting tube 72 moves up and down, it drives the blowing plate 78 to rise and fall and rotate, thereby adjusting the blowing direction.

[0056] During the rotation of the blowing plate 78, gas flows from the fixed tube 71 into the blowing plate 78 through the air guide tube and is ejected from the outlet of the blowing plate 78, forming a directional airflow. This allows for large-area blowing operations within the charging layer 4 and the platform layer 5. Since the angle of the blowing plate 78 can be adjusted with the movement of the threaded lifting tube 72, the blowing assembly 75 can flexibly adjust the direction and range of the blowing to dissipate the moisture accumulated in the charging layer 4 and the platform layer 5, thereby preventing potential damage to the electronic components within these areas. At the same time, the airflow generated by the blowing plate 78 can also carry away the heat generated by the wireless charging module during operation, thereby achieving a heat dissipation effect, and blow away dust on the drone platform 6.

[0057] Furthermore, the helical fit of the threaded lifting tube 72 and the toothed ring 82 makes the lifting and rotating movements of the device smoother and more precise, improving the accuracy and reliability of detection. The entire device is compact and easy to operate, significantly improving the efficiency and quality of tunnel safety inspections.

[0058] The driving member can be any device or apparatus in the prior art that can drive the gear ring 82 to rotate, and is not shown in the figure.

[0059] The UAV platform 6 includes a base 61, a rotating base 62 and a UAV base 63. The base 61 is slidably arranged on the inner bottom wall of the shell 1 through a slide rail. The rotating base 62 is installed in the middle of the base 61, and the UAV base 63 is installed on the rotating base 62.

[0060] The cleaning mechanism 8 includes a connecting block 86, which is fixedly sleeved on the outer wall of the fixed tube 71. The side of the connecting block 86 facing the drone platform 6 is fixedly connected to a mounting plate 87, and a cleaning brush is detachably connected to the mounting plate 87.

[0061] When a drone conducts safety inspections in a tunnel, dust or other impurities may accumulate on the drone platform 6. By rotating the base 62 to drive the drone base to rotate, the cleaning brush contacts the surface of the drone platform 6, thereby sweeping away dust and impurities on the drone base 63, ensuring the cleanliness of the drone platform 6, thereby preventing impurities from interfering with the operation of the drone and ensuring the cleanliness of the platform. In addition, this detachable connection method makes it easy for users to replace or clean the cleaning brush to maintain its cleaning effect and durability.

[0062] The top of the first sleeve 73 is connected to the signal relay layer 3 , the top of the shell 1 is arc-shaped, and heat dissipation vents 11 are provided on the sealing doors 9 located at the signal relay layer 3 and the charging layer 4 .

[0063] The signal relay module and the wireless charging module will generate a certain amount of heat during operation. If the heat is not dissipated in time, the stable operation of the device may be affected. Therefore, by opening a heat dissipation port 11 on the sealed door 9 of the signal relay layer 3 and the charging layer 4, since the first sleeve 73 is connected to the signal relay layer 3, when the air inside the first sleeve 73 enters the signal relay layer 3, it will first blow on the top of the arc, and the air will blow on the signal relay module along the curvature of the arc, and finally be discharged through the heat dissipation port 11. Similarly, the heat in the charging layer 4 is blown by the blowing component 75 and finally discharged through the heat dissipation port 11, which can effectively promote the air circulation inside the shell 1 and accelerate the dissipation of heat, thereby ensuring that the device can still maintain stable performance during long-term operation.

[0064] Fixing plates 12 are fixedly connected to both sides of the exterior of the housing 1 . Through slots 13 are defined inside the two fixing plates 12 . Inserting rods 14 are inserted into the two through slots 13 .

[0065] By fixing the two insertion rods 14 on the tunnel side wall, the shell 1 is stably fixed on the tunnel side wall as a whole, which is convenient for operation and easy maintenance or replacement of the shell 1 as a whole.

[0066] The scope of protection of the application is defined by the claims. Those skilled in the art may make various modifications or equivalent substitutions to the present application within the essence and scope of protection of the present application, and such modifications or equivalent substitutions shall also be deemed to fall within the scope of protection of the present application.
