Description

Technical Field

[0001] This utility model relates to the field of downhole monitoring device technology, specifically to a downhole LoRa transceiver device for tubular wells that is resistant to electromagnetic interference. Background Technology

[0002] To achieve the goal of actively detecting the concentration of combustible gases and liquid levels in wells while providing good protection, monitoring devices need to be installed on the manhole covers to monitor the underground environment in real time. This can significantly improve public safety and management efficiency, provide a basis for dynamic management of infrastructure for smart cities, and ultimately form a closed loop of "monitoring-early warning-response", which can significantly enhance urban resilience.

[0003] Existing monitoring devices do not have manhole cover displacement sensors. While displacement sensors can detect when the manhole cover is lifted and upload information promptly, they lack temperature and humidity sensors, making it impossible to detect real-time underground environmental conditions, thus posing certain safety hazards. Furthermore, when the monitoring device is damaged, the entire manhole cover needs to be flipped over for repair and maintenance, which is cumbersome and labor-intensive. Therefore, those skilled in the art provide an electromagnetic interference-resistant LoRa transceiver for underground manholes to solve the problems mentioned in the background art.

[0022] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0023] Please see Figures 1-6 This utility model provides a technical solution: an anti-electromagnetic interference LoRa transceiver for a manhole, comprising a manhole cover body 1, a lifting assembly 2 for raising and lowering installed at the lower center of the manhole cover body 1, a monitoring assembly 3 for detecting the safety status of the manhole installed at the center inside the lifting assembly 2, a fixing assembly 4 for fixing the lifting assembly 2 installed at the upper part inside the lifting assembly 2, a displacement sensor 6 for detecting whether the manhole cover has moved fixedly installed on the lower end face of the manhole cover body 1, a communication device 7 for receiving and transmitting data from the monitoring assembly 3 and the displacement sensor 6 fixedly installed on the lower end face of the manhole cover body 1, and two battery packs 5 for powering the monitoring assembly 3, the displacement sensor 6 and the communication device 7 fixedly installed at the lower end of the manhole cover body 1, the two battery packs 5 being symmetrically arranged.

[0024] This device, through the coordinated operation of monitoring component 3, displacement sensor 6, and communication equipment 7, achieves real-time monitoring of the manhole cover body 1 and the underground environment. Data is transmitted in real-time via communication equipment 7, significantly reducing manual inspection costs and effectively preventing accidents such as falls into the manhole or gas explosions caused by missing manhole covers. When maintenance of monitoring component 3 is required, rotating knob 408 removes the limiting block 405 from the limiting groove 407. The user can then remove the installation block 202 from the manhole cover body 1 to inspect and maintain monitoring component 3 without needing to remove the manhole cover body 1 first. The monitoring component 3 is easy to maintain and operate, thus reducing the workload of staff. It is worth noting that the battery pack 5, displacement sensor 6, and communication device 7 are all existing technologies. The battery pack 5 powers the displacement sensor 6 and communication device 7. The displacement sensor 6 monitors the tilt, displacement, flipping, and other abnormal states of the manhole cover body 1 in real time, reducing the risk of safety accidents caused by the missing or displaced manhole cover body 1. The communication device 7 is an LOR communication device, which is a wireless communication terminal based on low power wide area network technology. It can upload real-time monitoring data to the management platform, so it will not be described in detail here.

[0025] As one implementation method in this embodiment, please refer to Figures 3-4 As shown, the lifting assembly 2 includes an installation port 201, which is opened through the center of the manhole cover body 1. An installation block 202 slides inside the installation port 201. A connecting block 207 is fixedly connected to the lower end face of the installation block 202. Multiple bolts 204 are arranged in a ring and rotated around the center of the connecting block 207 near its edge. Multiple internal threaded holes 205 are arranged in a ring at the lower part of the installation block 202. The assembly ends of the multiple bolts 204 are threaded into the multiple internal threaded holes 205 respectively. A lifting frame 203 is fixedly connected to the lower end of the connecting block 207. A limiting ring 206 is fixedly fitted inside the lower part of the installation port 201.

[0026] When the data transmitted by the communication device 7 regarding the monitoring component 3 is abnormal, the installation block 202 can be directly removed from the installation port 201, and the monitoring component 3 between the connecting block 207 and the lifting frame 203 can be removed for maintenance. It is not necessary to remove the manhole cover body 1 before maintaining the monitoring component 3. The operation is portable, thereby reducing the workload of the staff.

[0027] As one implementation method in this embodiment, please refer to Figure 3 and Figure 6As shown, the fixing component 4 includes a rotating cavity 401, which is located at the center of the mounting block 202. A first bevel gear 402 is rotatably connected to one inner wall of the rotating cavity 401, and a second bevel gear 403 is rotatably connected to the upper inner wall of the rotating cavity 401. The first bevel gear 402 and the second bevel gear 403 mesh with each other. A moving groove 404 is provided on the side wall of the mounting block 202, and a limit block 405 is slidably connected to the inner wall of the moving groove 404. The rotating shaft of the first bevel gear 402 on one side passes through one inner wall of the rotating cavity 401 and extends into the moving groove 404. A threaded rod 406 is fixedly connected to the output end of gear 402. The threaded rod 406 is threadedly sleeved at the center of the inner part of the limiting block 405. A limiting groove 407 is opened on the inner wall of the mounting port 201. The limiting block 405 and the limiting groove 407 cooperate with each other. A placement groove 409 is opened at the center of the upper end of the mounting block 202. The rotating shaft of the second bevel gear 403 at the upper end passes through the inner wall of the rotating cavity 401 and leads to the inside of the placement groove 409. A knob 408 is fixedly connected to the upper end of the rotating shaft of the second bevel gear 403. The knob 408 is rotated and sleeved in the placement groove 409.

[0028] When removing the monitoring component 3 for maintenance, rotating the knob 408 causes the second bevel gear 403 in the rotating cavity 401 to rotate. The second bevel gear 403 drives the first bevel gear 402 to rotate, causing the threaded rod 406 in the moving groove 404 to start rotating. The limiting block 405 then slides out from the limiting groove 407 and moves completely into the moving groove 404. The user can then remove the installation block 202 from the manhole cover body 1. When installing the installation block 202, align the installation block 202 with the installation opening 201, and ensure that the limiting block 405 on the installation block 202 is directly opposite the limiting groove. 407. At this point, the mounting block 202 is pressed into the mounting port 201. The lower end of the mounting block 202 will contact the limiting ring 206, thereby initially limiting the mounting block 202 and preventing it from continuing to descend. Then, the user rotates the knob 408 in the opposite direction. Rotating the knob 408 in the opposite direction means rotating it in the opposite direction to rotating it during disassembly. Under the transmission of the first bevel gear 402 and the second bevel gear 403, the threaded rod 406 rotates, and the limiting block 405 slides into the limiting groove 407, thereby fixing the mounting block 202 and improving its stability.

[0029] As one implementation method in this embodiment, please refer to Figure 5As shown, the monitoring component 3 includes a device battery 301, which is fixedly connected to the lower center of the mounting block 202. A gas sensor body 302 is fixedly connected to the lower end of the device battery 301. A temperature and humidity sensor 303 is fixedly connected to the lower end of the gas sensor body 302. A four-in-one gas sensor 304 is fixedly connected to the lower end of the temperature and humidity sensor 303. A liquid level sensor 305 is fixedly connected to the lower end of the four-in-one gas sensor 304. The lower end of the liquid level sensor 305 is fixedly connected to the lower inner wall center of the lifting frame 203.

[0030] The battery 301 powers the gas sensor body 302, temperature and humidity sensor 303, four-in-one gas sensor 304, and liquid level sensor 305. It's worth noting that the gas sensor body 302, temperature and humidity sensor 303, four-in-one gas sensor 304, and liquid level sensor 305 are all existing technologies. These devices work together to monitor the downhole environment, which will not be elaborated further here. The gas sensor body 302, in conjunction with the four-in-one gas sensor 304, detects the concentration of flammable and explosive gases in the downhole environment in real time to prevent explosions, identifies highly toxic gases to prevent poisoning, and monitors oxygen content. The temperature and humidity sensor 303 is used to monitor the temperature of the downhole air. Temperature and relative humidity are monitored to ensure the working environment meets safety standards. The liquid level sensor 305 mainly monitors the depth of water, sewage or other liquids in the well environment, and provides real-time feedback on water level changes to prevent accidents such as water inrush and well flooding. The displacement sensor 6 monitors the tilt, displacement, flipping and other abnormal states of the manhole cover body 1 in real time, reducing the risk of safety accidents caused by the missing or displaced manhole cover body 1. The monitoring component 3 works with the displacement sensor 6 and uploads the real-time monitoring data to the management platform through the communication device 7 to realize real-time monitoring of the manhole cover body 1 and the well environment, greatly reducing the cost of manual inspection, effectively avoiding safety accidents such as falling into the well or gas explosions caused by missing manhole covers, and making the monitoring more comprehensive and effective.

[0031] As one implementation method in this embodiment, please refer to Figure 1 As shown, there are two drainage outlets 8 inside the manhole cover body 1. The two drainage outlets 8 are symmetrically arranged. Multiple anti-slip pads 9 are arranged in a ring and fixedly connected at the center of the upper end face of the manhole cover body 1 near the edge.

[0032] Drainage outlet 8 allows rainwater to flow quickly into the underground pipe network, preventing water accumulation on the road surface from causing slippage or vehicle splashing accidents. At the same time, drainage outlet 8 can be used as a hook point or pry bar insertion position, allowing maintenance personnel to quickly pry up the manhole cover body 1 without special tools, significantly improving emergency repair efficiency.

[0033] As one implementation method in this embodiment, please refer to Figure 2 and Figure 3As shown, the upper surface of the knob 408 has a groove 10, and multiple reinforcing ribs 11 are arranged in a ring and fixedly connected at the center of the lower surface of the manhole cover body 1 near the edge.

[0034] The groove 10 is designed to facilitate the use of a device, such as a flathead screwdriver, to rotate the knob 408 by inserting it into the groove 10, thus making operation easier. The reinforcing rib 11 enhances the load-bearing capacity and rigidity of the manhole cover body 1, thereby increasing the service life of the manhole cover body 1.

[0035] Working Principle: This device uses a gas sensor body 302 in conjunction with a four-in-one gas sensor 304 to detect the concentration of flammable and explosive gases in the underground environment in real time to prevent explosions, identify highly toxic gases to prevent poisoning, and monitor oxygen content. A temperature and humidity sensor 303 monitors the temperature and relative humidity of the underground air to ensure the working environment meets safety standards. A liquid level sensor 305 primarily monitors the depth of accumulated water, sewage, or other liquids in the underground environment, providing real-time feedback on water level changes to prevent accidents such as water inrush and well flooding. A displacement sensor 6 monitors the tilt, displacement, and overturning of the manhole cover body 1 in real time. To reduce the risk of safety accidents caused by missing or displaced manhole cover 1, the monitoring component 3, in conjunction with the displacement sensor 6, uploads real-time monitoring data to the management platform via the communication device 7. This enables real-time monitoring of the manhole cover 1 and the underground environment, significantly reducing manual inspection costs and effectively preventing accidents such as falls into manholes or gas explosions caused by missing manhole covers. The monitoring is more comprehensive and effective. When the data transmitted by the communication device 7 regarding the monitoring component 3 is abnormal, and maintenance of the monitoring component 3 is required, the second bevel gear 403 inside the rotating cavity 401 rotates by turning the knob 408. 3 drives the first bevel gear 402 to rotate, and the threaded rod 406 located in the moving groove 404 begins to rotate. The limiting block 405 then slides out from the limiting groove 407 and moves completely into the moving groove 404. The user can then remove the mounting block 202 from the manhole cover body 1 to inspect and maintain the monitoring component 3 installed on the connecting block 207. This eliminates the need to remove the manhole cover body 1 before maintaining the monitoring component 3, making the operation convenient and reducing the workload of the staff. When installing the mounting block 202, align the mounting block 202 with the mounting opening 201, and ensure the limiting block 405 on the mounting block 202 is in place. Block 405 needs to be aligned with the limiting groove 407. At this time, the mounting block 202 is pressed into the mounting port 201. The lower end of the mounting block 202 will contact the limiting ring 206, thereby achieving initial limiting of the mounting block 202 and preventing the mounting block 202 from continuing to descend. Then, the user rotates the knob 408 in the opposite direction. Rotating the knob 408 in the opposite direction means rotating it in the opposite direction to rotating the knob 408 during disassembly. Under the transmission of the first bevel gear 402 and the second bevel gear 403, the threaded rod 406 rotates, and the limiting block 405 slides into the limiting groove 407, thereby fixing the mounting block 202 and improving the stability of the mounting block 202.

[0036] The above embodiments are only used to illustrate the technical solution of this utility model, and are not intended to limit it.
