Description

Technical Field

[0001] This invention relates to the field of power tunnel construction technology, specifically to a power tunnel safety monitoring construction system and method. Background Technology

[0002] Currently, power tunnels, also known as cable tunnels, refer to corridor or tunnel-like structures used to accommodate large numbers of cables laid on cable supports. Besides providing better protection for the cables, cable tunnels also facilitate cable inspection and maintenance. However, the long, narrow tunnels and various obstructions during construction pose significant safety threats to construction workers. Therefore, construction companies typically implement safety measures to ensure safe construction.

[0003] A patent application with publication number CN111156008A protects a method for shield tunneling and monitoring of a power tunnel under a dangerous river source. The method includes the following steps: (1) reinforcing the tunnel interior before it crosses the river; (2) shield tunneling under the river; (3) shield tunneling under the power tunnel; and (4) construction monitoring. This invention improves each step, achieving high-quality and safe tunneling under the river and under the power tunnel.

[0004] In the above technical solutions, during the construction of power tunnels, due to the narrowness and complex environment of the tunnels, it is difficult to grasp the specific situation at the construction site once a safety accident occurs, which makes it difficult to carry out rescue quickly. Summary of the Invention

[0005] To address the challenges of accurately assessing the specific conditions at the construction site and facilitating rapid rescue operations in existing power tunnel construction methods, this invention provides a power tunnel safety monitoring construction system and method.

[0006] The technical solution of this invention is as follows:

[0007] On one hand, the present invention provides a power tunnel safety monitoring construction system, including multiple field monitoring devices, a monitoring mobile terminal and a monitoring cloud. The field monitoring devices include a mounting bracket, a moving component that drives the mounting bracket to move, an image acquisition device and an environmental monitoring device connected to the mounting bracket, a data transmission line that is fixedly connected to both the image acquisition device and the environmental monitoring device, a wireless communication device that is fixedly connected to the other end of the data transmission line, and a winding component that winds the data transmission line connected to the mounting bracket.

[0008] The image acquisition device of the on-site monitoring equipment acquires image information, and the environmental detection device detects the temperature, air humidity, harmful gas concentration and oxygen concentration around the on-site monitoring equipment.

[0009] The monitoring cloud receives image information, temperature value, air humidity value, harmful gas concentration value, and oxygen concentration value from the on-site monitoring equipment. The monitoring cloud has pre-stored standard values ​​for temperature, air humidity, harmful gas concentration, and oxygen concentration. When the temperature value exceeds the standard value, the air humidity value exceeds the standard value, the harmful gas concentration value exceeds the standard value, or the oxygen concentration value is lower than the standard value, the monitoring cloud sends an alarm signal, image information, temperature value, air humidity value, harmful gas concentration value, and oxygen concentration value to the monitoring mobile terminal.

[0010] The monitoring mobile terminal receives alarm signals, image information, temperature values, air humidity values, harmful gas concentration values, and oxygen concentration values, then issues an alarm and displays the image information, temperature values, air humidity values, harmful gas concentration values, and oxygen concentration values.

[0011] The beneficial effects achieved by this invention are as follows: This system can monitor the situation inside power tunnels in real time. Users can view images, temperature, humidity, and other information inside the tunnel in real time through a mobile monitoring device. When an anomaly occurs inside the power tunnel, the system can automatically detect it and issue an alarm, facilitating timely response and rescue by staff. Simultaneously, the on-site monitoring equipment can move within the power tunnel, eliminating the need for manual relocation by users. This effectively reduces the workload of staff in confined tunnels, enabling the system to detect information about the construction area within the power tunnel in real time. The data transmission cable can be extended over long distances via a winding assembly, ensuring good signal quality for the wireless communication equipment and allowing the monitoring cloud to receive accurate data.

[0012] Furthermore, the movable component includes a connecting plate fixedly connected to a mounting bracket, a first bracket fixedly connected to the connecting plate, a plurality of first vacuum suction cups fixedly connected to the first bracket, each of the first vacuum suction cups being fixedly connected to a first connecting tube, the other end of the first connecting tube being fixedly connected to a first vacuum pump, a second bracket slidably connected to the connecting plate, the second bracket sliding along the length direction of the connecting plate, a plurality of second vacuum suction cups fixedly connected to the second bracket, each of the second vacuum suction cups being fixedly connected to a second connecting tube, the other end of the second connecting tube being fixedly connected to a second vacuum pump;

[0013] The second bracket has a threaded rod connected to it. The threaded rod is rotatably connected to the connecting plate. The threaded rod is set along the length of the connecting plate, and a drive motor is fixedly connected to one end of the threaded rod.

[0014] The above solution allows the first and second vacuum suction cups to be fixed on the sidewalls or even the ceiling of the power tunnel without damaging the tunnel walls. This facilitates the movement of the monitoring equipment with the staff and maintains accurate monitoring position. When the monitoring equipment needs to be moved, the second vacuum pump is first depressurized, causing the second vacuum suction cup to lose its suction. At this point, the drive motor rotates the threaded rod, and because the first bracket is fixed, it moves the second bracket. Then, the second vacuum pump draws in air, causing the second vacuum suction cup to adhere to the tunnel wall. The first vacuum pump then depresses, causing the first vacuum suction cup to lose its suction. The drive motor then reverses the threaded rod, causing the first bracket to move because the second bracket is fixed. Finally, the first vacuum pump draws in air, causing the first vacuum suction cup to adhere to the tunnel wall, thus enabling the monitoring equipment to be moved.

[0015] Furthermore, the on-site monitoring equipment includes an image acquisition module, a data acquisition module, a data transmission module, and a motion control module;

[0016] The image acquisition module controls the image acquisition device to capture images and transmit image information;

[0017] The data acquisition module controls the environmental monitoring equipment to detect and transmit temperature, humidity, harmful gas concentration, and oxygen concentration values.

[0018] The data transmission module receives image information from the image acquisition module and temperature, air humidity, harmful gas concentration, and oxygen concentration values ​​from the data acquisition module, and sends them to the monitoring cloud via the wireless communication module.

[0019] After receiving the input movement command, the movement control module controls the movement component to move the on-site monitoring equipment.

[0020] The monitoring cloud includes a data pre-storage module, a data transmission and reception module, and a data comparison module;

[0021] The data pre-storage module pre-stores standard values ​​for temperature, air humidity, harmful gas concentration, and oxygen concentration.

[0022] The data transceiver module receives image information, temperature value, air humidity value, harmful gas concentration value and oxygen concentration value sent by the data transmission module, and transmits the alarm signal, image information, temperature value, air humidity value, harmful gas concentration value and oxygen concentration value to the monitoring mobile terminal.

[0023] The data comparison module compares the temperature value with the temperature standard value, the air humidity value with the air humidity standard value, the harmful gas concentration value with the harmful gas concentration standard value, and the oxygen concentration value with the oxygen concentration standard value. When the temperature value exceeds the temperature standard value, the air humidity value exceeds the air humidity standard value, the harmful gas concentration value exceeds the harmful gas concentration standard value, or the oxygen concentration value is lower than the oxygen concentration standard value, the data comparison module transmits an alarm signal to the data transceiver module.

[0024] The monitoring mobile terminal includes an information receiving module and an information display module;

[0025] The information receiving module receives alarm signals, image information, temperature values, air humidity values, harmful gas concentration values, and oxygen concentration values ​​transmitted by the data transceiver module.

[0026] The information display module displays the received alarm signals, image information, temperature value, air humidity value, harmful gas concentration value, and oxygen concentration value.

[0027] The above solution utilizes multiple modules to ensure the normal operation of the system.

[0028] Furthermore, after receiving the input movement command, the movement control module controls the second vacuum pump to release gas, drives the motor to rotate forward, controls the second vacuum pump to draw a vacuum after a set time, then controls the first vacuum pump to release gas, drives the motor to rotate in reverse, controls the first vacuum pump to draw a vacuum after a set time, and the drive motor stops working.

[0029] With the above scheme, when the on-site monitoring equipment needs to be moved, the second vacuum pump is first depressurized, causing the second vacuum suction cup to lose its suction. At this time, the drive motor drives the threaded rod to rotate. Since the first bracket is fixed, the second bracket is moved. Then, the second vacuum pump draws in air, causing the second vacuum suction cup to adhere to the tunnel wall. The first vacuum pump then depresses, causing the first vacuum suction cup to lose its suction. At this time, the drive motor drives the threaded rod to reverse. Since the second bracket is fixed, the first bracket is moved. Then, the first vacuum pump draws in air, causing the first vacuum suction cup to adhere to the tunnel wall, completing the movement.

[0030] Furthermore, a groove is provided on the connecting plate at the position corresponding to the second bracket. The groove is set along the length direction of the connecting plate, and the second bracket is slidably connected in the groove. The threaded rod is threadedly connected to the second bracket at the position corresponding to the groove.

[0031] The above solution makes the movement trajectory of the second support more stable.

[0032] Furthermore, the winding assembly includes a winding bracket fixedly connected to the mounting bracket, a winding roller rotatably connected to the winding bracket, and a handle fixedly connected to one end of the winding roller.

[0033] Using the above method, staff can simply turn the handle to rewind or unwind the data transmission cable.

[0034] Furthermore, environmental monitoring equipment includes humidity sensors, temperature sensors, harmful gas sensors, and oxygen concentration sensors.

[0035] The above scheme uses a humidity sensor to detect humidity, a temperature sensor to detect temperature, a harmful gas sensor to select the specific gas to detect based on the specific situation, and an oxygen concentration sensor to detect oxygen concentration.

[0036] Furthermore, an adjustment panel is rotatably connected to the mounting bracket near the image acquisition device. The image acquisition device is fixedly connected to the adjustment panel. A rotating shaft is fixedly connected to the adjustment panel. A worm gear is fixedly connected to the rotating shaft. A worm is fixedly connected to the mounting bracket near the worm gear. The worm meshes with the worm gear.

[0037] Using the above method, staff can adjust the direction of the image acquisition device by rotating the worm gear, thereby adjusting the shooting angle.

[0038] On the other hand, the present invention provides a construction method for safety monitoring of power tunnels, based on the above-mentioned power tunnel safety monitoring construction system, comprising the following steps:

[0039] Deploy on-site monitoring equipment at the construction site, pull out the data transmission line, and keep the wireless communication equipment in a location with good signal.

[0040] Image acquisition equipment acquires images, while environmental monitoring equipment detects temperature, humidity, harmful gas concentration, and oxygen concentration around the on-site monitoring equipment.

[0041] The wireless communication device sends the collected image information, temperature values, air humidity values, harmful gas concentration values, and oxygen concentration values ​​to the monitoring cloud.

[0042] The monitoring cloud periodically compares temperature, air humidity, harmful gas concentration, and oxygen concentration. When the temperature exceeds the standard value, the air humidity exceeds the standard value, the harmful gas concentration exceeds the standard value, or the oxygen concentration is lower than the standard value, the monitoring cloud sends an alarm message to the monitoring mobile terminal. The monitoring cloud also transmits image information, temperature, air humidity, harmful gas concentration, and oxygen concentration to the monitoring mobile terminal in real time.

[0043] The monitoring mobile device receives and displays image information, temperature values, air humidity values, harmful gas concentration values, and oxygen concentration values. It also issues an alarm after receiving an alarm message on the monitoring mobile device.

[0044] The beneficial effects achieved by this invention are as follows: This method can monitor the situation inside the power tunnel in real time. Users can view images and information such as temperature and humidity inside the tunnel in real time through the monitoring mobile terminal. When an abnormality occurs inside the power tunnel, the system can automatically detect it and issue an alarm, which facilitates timely response or rescue by staff.

[0045] The power tunnel safety monitoring construction system and method of the present invention have the following advantages:

[0046] 1. This method can monitor the situation inside the power tunnel in real time. Users can view images and information such as temperature and humidity inside the tunnel in real time through the monitoring mobile device. When an abnormality occurs in the power tunnel, the system can automatically detect it and issue an alarm, which facilitates timely response or rescue by staff.

[0047] 2. The data transmission cable can be extended over a long distance through the winding component, ensuring good signal quality for wireless communication devices and enabling the monitoring cloud to receive accurate data.

[0048] 3. The first and second vacuum suction cups allow the on-site monitoring equipment to be fixed on the side wall or even the top wall of the power tunnel without damaging the tunnel wall, making it easy for the on-site monitoring equipment to move with the staff and maintain accurate monitoring position.

[0060] Example 1: This invention provides a power tunnel safety monitoring construction system, such as... Figure 1As shown, the system includes multiple on-site monitoring devices 1, mobile monitoring terminals 2, and a cloud monitoring platform 3. The on-site monitoring devices 1 are installed at the construction site and positioned according to the tunnel construction progress. The mobile monitoring terminals 2 are installed on the mobile devices of on-site workers or rescue personnel. The cloud monitoring platform 3 is located on a cloud server.

[0061] like Figure 2 and Figure 3 As shown, the on-site monitoring device 1 includes a mounting bracket 11, on which an image acquisition device 13 and an environmental monitoring device 14 are connected. The image acquisition device 13 acquires image information. The environmental monitoring device 14 includes a humidity sensor 141, a temperature sensor 142, a hazardous gas sensor 143, and an oxygen concentration sensor 144. The humidity sensor 141 is used to detect humidity values, the temperature sensor 142 is used to detect temperature values, the hazardous gas sensor 143 selects a specific gas to detect according to the specific situation to detect the concentration of the corresponding gas, and the oxygen concentration sensor 144 is used to detect oxygen concentration.

[0062] like Figure 2 and Figure 3 As shown, the image acquisition device 13 and the environmental monitoring device 14 are both fixedly connected to a data transmission line 151, and the other end of the data transmission line 151 is fixedly connected to a wireless communication device 15. A winding assembly 16 is connected to the mounting bracket 11. The winding assembly 16 includes a winding bracket 161 fixedly connected to the mounting bracket 11, a winding roller 162 rotatably connected to the winding bracket 161, and a handle 163 fixedly connected to one end of the winding roller 162. The operator can turn the handle 163 to wind or unwind the data transmission line 151.

[0063] like Figure 3 and Figure 4 As shown, an adjustment panel 131 is rotatably connected to the mounting bracket 11 near the image acquisition device 13. The image acquisition device 13 is fixedly connected to the adjustment panel 131. A rotating shaft 132 is fixedly connected to the adjustment panel 131, and a worm gear 133 is fixedly connected to the rotating shaft 132. A worm 134 is fixedly connected to the mounting bracket 11 near the worm gear 133, and the worm 134 meshes with the worm gear 133. By rotating the worm 134, the operator can adjust the direction of the image acquisition device 13, thereby adjusting the shooting angle.

[0064] like Figure 5 and Figure 6As shown, a mounting bracket 11 is connected to a movable component 12, which includes a connecting plate 121 fixedly connected to the mounting bracket 11. A first bracket 122 is fixedly connected to the connecting plate 121, and a plurality of first vacuum suction cups 123 are fixedly connected to the first bracket 122. Each first vacuum suction cup 123 is fixedly connected to a first connecting tube 1231, and the other end of the first connecting tube 1231 is fixedly connected to a first vacuum pump 1232. A second bracket 124 is slidably connected to the connecting plate 121 and slides along the length of the connecting plate 121. A plurality of second vacuum suction cups 125 are fixedly connected to the second bracket 124, and each second vacuum suction cup 125 is fixedly connected to a second connecting tube 1251. The other end of the second connecting tube 1251 is fixedly connected to a second vacuum pump 1252. The second bracket 124 is threadedly connected to a threaded rod 126, which is rotatably connected to the connecting plate 121. The threaded rod 126 is set along the length of the connecting plate 121, and a drive motor 127 is fixedly connected to one end of the threaded rod 126. The first vacuum suction cup 123 and the second vacuum suction cup 125 allow the on-site monitoring equipment 1 to be fixed on the side wall or even the top wall of the power tunnel without damaging the tunnel wall, making it easy for the on-site monitoring equipment 1 to move with the staff and maintain accurate monitoring position. When the on-site monitoring equipment 1 needs to be moved, the second vacuum pump 1252 can be depressurized first, causing the second vacuum suction cup 125 to lose its suction. At this time, the drive motor 127 drives the threaded rod 126 to rotate. Since the first bracket 122 is fixed, the second bracket 124 is moved. Then, the second vacuum pump 1252 draws in air, causing the second vacuum suction cup 125 to adhere to the tunnel wall. The first vacuum pump 1232 depresses air, causing the first vacuum suction cup 123 to lose its suction. At this time, the drive motor 127 drives the threaded rod 126 to reverse. Since the second bracket 124 is fixed, the first bracket 122 is moved. Then, the first vacuum pump 1232 draws in air, causing the first vacuum suction cup 123 to adhere to the tunnel wall, thus enabling the on-site monitoring equipment 1 to be moved.

[0065] like Figure 7As shown, the on-site monitoring device 1 includes an image acquisition module 17, a data acquisition module 171, a data transmission module 172, and a motion control module 173. The image acquisition module 17 controls the image acquisition device 13 to capture images and transmit image information. The data acquisition module 171 controls the environmental monitoring device 14 to detect and transmit temperature, humidity, harmful gas concentration, and oxygen concentration values. The data transmission module 172 receives the image information from the image acquisition module 17 and the temperature, humidity, harmful gas concentration, and oxygen concentration values ​​from the data acquisition module 171, and sends them to the monitoring cloud 3 via a wireless communication module. Upon receiving an input motion command, the motion control module 173 controls the second vacuum pump 1252 to release gas, drives the motor 127 to rotate forward, and after a set time, controls the second vacuum pump 1252 to create a vacuum. Then, it controls the first vacuum pump 1232 to release gas, drives the motor 127 to rotate in reverse, and after a set time, controls the first vacuum pump 1232 to create a vacuum, and the motor 127 stops working.

[0066] like Figure 7 As shown, the monitoring cloud 3 includes a data pre-storage module 31, a data transceiver module 32, and a data comparison module 33. The data pre-storage module 31 pre-stores standard values ​​for temperature, air humidity, harmful gas concentration, and oxygen concentration. The data transceiver module 32 receives image information, temperature, air humidity, harmful gas concentration, and oxygen concentration values ​​sent by the data transmission module 172, and transmits alarm signals, image information, temperature, air humidity, harmful gas concentration, and oxygen concentration values ​​to the monitoring mobile terminal 2. The data comparison module 33 processes and compares the temperature value with the standard temperature value, the air humidity value with the standard air humidity value, the harmful gas concentration value with the standard harmful gas concentration value, and the oxygen concentration value with the standard oxygen concentration value. When the temperature value exceeds the standard temperature value, the air humidity value exceeds the standard air humidity value, the harmful gas concentration value exceeds the standard harmful gas concentration value, or the oxygen concentration value falls below the standard oxygen concentration value, the data comparison module 33 transmits an alarm signal to the data transceiver module 32.

[0067] like Figure 7 As shown, the monitoring mobile terminal 2 includes an information receiving module 21 and an information display module 22. The information receiving module 21 receives alarm signals, image information, temperature values, air humidity values, harmful gas concentration values, and oxygen concentration values ​​transmitted by the data transceiver module 32. The information display module 22 displays the received alarm signals, image information, temperature values, air humidity values, harmful gas concentration values, and oxygen concentration values.

[0068] The present invention provides a power tunnel safety monitoring construction system. The system's implementation principle is as follows: This system can monitor the situation inside the power tunnel in real time. Users can view images, temperature, humidity, and other information inside the tunnel in real time through the monitoring mobile terminal 2. When an abnormality occurs inside the power tunnel, the system can automatically detect it and issue an alarm, facilitating timely response or rescue by staff. Simultaneously, the on-site monitoring device 1 can move within the power tunnel, eliminating the need for manual relocation by the user. This effectively reduces the workload of staff in the confined space of the tunnel, enabling the system to detect information about the construction area in the power tunnel in real time. The data transmission line 151 can extend a long distance through the winding assembly 16, ensuring good signal quality for the wireless communication device 15 and allowing the monitoring cloud 3 to receive accurate data.

[0069] Example 2: This invention provides a method for safety monitoring construction in power tunnels, based on the power tunnel safety monitoring construction system of Example 1. The specific steps are as follows:

[0072] S3, the wireless communication device 15 sends the collected image information, temperature value, air humidity value, harmful gas concentration value and oxygen concentration value to the monitoring cloud 3.

[0073] S4. The monitoring cloud 3 periodically compares the temperature value, air humidity value, harmful gas concentration value and oxygen concentration value. When the temperature value exceeds the temperature standard value, the air humidity value exceeds the air humidity standard value, the harmful gas concentration value exceeds the harmful gas concentration standard value, or the oxygen concentration value is lower than the oxygen concentration standard value, the monitoring cloud 3 sends an alarm information to the monitoring mobile terminal 2. The monitoring cloud 3 transmits the image information, temperature value, air humidity value, harmful gas concentration value and oxygen concentration value to the monitoring mobile terminal 2 in real time.

[0074] S5. The monitoring mobile terminal 2 receives and displays image information, temperature value, air humidity value, harmful gas concentration value and oxygen concentration value, and issues an alarm after receiving alarm information.
