Description

Technical Field

[0001] The present invention relates to the technical field of tunnel deicing, and in particular to a tunnel disaster early warning method. Background Art

[0002] The climate varies greatly from place to place. In winter, most parts of my country are in cold zones, and some parts are in extremely cold zones. If a tunnel leaks in such areas, the side walls and arches of the tunnel will be covered with ice. In severe cases, the railway line will also freeze due to the infiltration of water leakage. In non-electrified railway tunnels, there are many electrical equipment, which can easily cause accidents such as equipment tripping or leakage. In electrified railway tunnels, it is very easy to cause high-voltage grounding short circuit failures in contact network equipment, posing a great threat to the power supply of the tunnel. At the least, the contact network wires will be burned and broken, and at the worst, the wires will break and the network will collapse, interrupting railway transportation. Therefore, this situation seriously affects the normal operation of the tunnel.

[0003] In the relevant technology, deicing in non-electrified tunnels is done manually during the intervals between train operations; deicing in electrified railway tunnels is done during power outages. Manual deicing is extremely dangerous and requires repeated deicing. The railway invests a large amount of manpower and material resources in tunnel deicing in winter every year. When ice is severe, the number of deicing times increases, the distance is long, the labor intensity is high, the line traffic density is high, the tunnel is long, the clearance is low, and dust pollution is serious when trains pass through, which poses a great danger to the life safety of deicing personnel and has low deicing efficiency. Summary of the invention

[0004] The main purpose of the present invention is to provide a tunnel disaster early warning method to solve the problem of low deicing efficiency in tunnels in the related art.

[0005] In order to achieve the above-mentioned purpose, the present invention provides a tunnel disaster warning method, comprising: step S10: a detection device detects multiple water seepage points in the tunnel and the water seepage area of ​​each water seepage point; step S20: a thickness detection sensor is installed at each water seepage point; step S30: the thickness detection sensor can detect the thickness of the ice layer at each water seepage point and transmit the thickness of the ice layer to a controller; step S40: the controller controls the heating plate in the tunnel to heat according to the thickness of the ice layer and turns on the conveyor belt; step S50: the melted ice cubes are transported to the outside of the tunnel by the conveyor belt.

[0006] Further, step S40 includes the following steps: step S41: when the thickness of the ice layer ranges from 20 mm to 100 mm, the controller controls the heating plate to heat the side wall of the tunnel; step S42: when the thickness of the ice layer is greater than 100 mm, the controller controls the heating plate to heat and controls the conveyor belt to start.

[0007] Furthermore, the tunnel disaster warning method also includes the following steps: Step S60: a gravity sensor is set at a predetermined position outside the tunnel, and the weight information can be transmitted to the controller through the gravity sensor; Step S70: the controller issues a transportation instruction according to the weight information, and the operator transports the ice at the predetermined position according to the transportation instruction.

[0008] Furthermore, step S80 is also included between step S40 and step S50: the controller transmits the start-up information of the heating plate and the conveyor belt to the train, and the train decelerates according to the start-up information to pass through the tunnel.

[0009] Furthermore, the detection device includes an infrared thermal imaging detection device and a laser non-destructive detection device, and the infrared thermal imaging detection device and the laser non-destructive detection device simultaneously detect water seepage points in the tunnel.

[0010] Furthermore, the heating plate is arranged on the water seepage point of the side wall of the tunnel, and the conveyor belt is located below the heating plate.

[0011] Furthermore, the conveyor belt is arranged in close contact with the side wall of the tunnel, and is arranged along the length direction of the tunnel.

[0012] Furthermore, the electricity for the heating plates and conveyor belts is provided by solar and wind energy.

[0013] Furthermore, a drainage ditch is provided at the bottom of the side wall of the tunnel. After the operation in step S41 is performed, the ice cubes melt into water and flow into the drainage ditch.

[0014] Furthermore, a heating device is provided on the side wall of the drainage ditch, and the temperature in the drainage ditch is continuously maintained at a predetermined temperature.

[0015] By applying the technical solution of the present invention, the water seepage points are first detected in the tunnel, and the area of ​​the water seepage is determined. A thickness detection sensor is installed at each water seepage point. The thickness detection sensor can detect the thickness of the ice layer at the water seepage point, and transmit the information of the ice layer thickness to the controller. The controller can process and control the heating plate in the tunnel to heat according to the thickness of the ice layer, and at the same time control the start of the conveyor belt in the tunnel. In this way, after the heating plate melts the ice, the ice can fall onto the conveyor belt, and the conveyor belt can transport the ice out of the tunnel. Through the above-mentioned settings, the icing situation in the tunnel can be monitored and handled in time, which not only ensures the safe operation of the train, but also improves the efficiency of deicing. Therefore, the technical solution of the present application effectively solves the problem of low deicing efficiency in the tunnel in the related art. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] The waterproofing technology of old tunnels was backward when they were built, and it is easy for water to seep and leak in the expansion joints, section joints, stone cracks and other parts of the tunnel. There are many water seepage and leakage points in old tunnels. In winter, they freeze and easily scratch the trains, posing a safety hazard to the normal operation of the trains. Daily manual foot inspections are carried out to eliminate ice damage and manually transport ice blocks out of the tunnel to ensure the safe operation of the trains. However, manual foot inspections are inefficient and labor-intensive, and ice damage points cannot be discovered in time and quickly eliminated. It is necessary to apply for construction skylights to eliminate ice damage and transport ice blocks, which is time-consuming and labor-intensive, and inefficient.

[0026] In order to solve the above problems, Figure 1 and Figure 3 As shown, in this embodiment, the tunnel disaster warning method includes: step S10: the detection device detects multiple water seepage points in the tunnel 10 and the water seepage area of ​​each water seepage point; step S20: the thickness detection sensor 20 is installed at each water seepage point; step S30: the thickness detection sensor 20 can detect the thickness of the ice layer at each water seepage point, and transmit the thickness of the ice layer to the controller; step S40: the controller controls the heating plate 30 in the tunnel 10 to heat according to the thickness of the ice layer, and turns on the conveyor belt 40; step S50: the melted ice cubes are transported to the outside of the tunnel 10 through the conveyor belt 40.

[0027] By applying the technical solution of this embodiment, the water seepage points are first detected in the tunnel 10, and the area of ​​water seepage is determined. A thickness detection sensor 20 is installed at each water seepage point. The thickness detection sensor 20 can detect the thickness of the ice layer at the water seepage point, and transmit the information of the ice layer thickness to the controller. The controller can process and control the heating plate 30 in the tunnel to heat according to the thickness of the ice layer, and control the conveyor belt 40 in the tunnel 10 to start at the same time. In this way, after the heating plate 30 melts the ice, the ice can fall onto the conveyor belt 40, and the conveyor belt 40 can transport the ice out of the tunnel. Through the above-mentioned settings, the icing situation in the tunnel 10 can be monitored and handled in time, which not only ensures the safe operation of the train, but also improves the efficiency of deicing. Therefore, the technical solution of this embodiment effectively solves the problem of low deicing efficiency in the tunnel in the related art.

[0028] In this embodiment, a tunnel leakage point detection device is also provided. A track is provided at the top of the tunnel. The tunnel leakage point detection device is provided on the track and can move along the track. Through the above-mentioned arrangement, the tunnel leakage point detection device can detect the situation in the tunnel at any time, so that the latest location information of the leakage point in the tunnel can be obtained at any time, so that the deicing in the tunnel can be controlled more effectively. Specifically, in this embodiment, the time for the tunnel leakage point detection device to move from the first end of the track to the second end of the track is 12 hours. The tunnel leakage point detection device includes a wide-angle lens, so that the situation in the tunnel can be monitored in all directions.

[0029] In this embodiment, a temperature detection device is further included, which is arranged in the tunnel and connected to the controller. When the temperature detected by the temperature detection device is less than or equal to -10°, the temperature detection device transmits the temperature information to the controller, and the controller starts the heating plate 30 and makes the power of the heating plate 30 in the first gear, that is, the temperature is between 60°C and 90°C. When the temperature detected by the temperature detection device is greater than -10°, the temperature detection device transmits the temperature information to the controller, and the controller starts the heating plate 30 and makes the power of the heating plate 30 in the second gear, that is, the temperature is between 20°C and 50°C.

[0030] In order to improve efficiency and avoid energy waste, such as Figures 1 to 3As shown, in this embodiment, step S40 includes the following steps: step S41: when the ice layer thickness ranges from 20 mm to 100 mm, the controller controls the heating plate 30 to heat the side wall of the tunnel 10; step S42: when the ice layer thickness is greater than 100 mm, the controller controls the heating plate 30 to heat and controls the conveyor belt 40 to start. If the ice layer thickness is small, it is only necessary to start the heating plate 30, so that the ice layer can be melted and no ice cubes will fall onto the track. Specifically, after a large number of on-site calculations by the inventor, when the ratio of the ice layer thickness to the width of the tunnel is less than 1:200, it is only necessary to turn on the heating plate. If the ice layer thickness is large, it is necessary to turn on the heating plate 30 and the conveyor belt 40 at the same time, so that the melted ice cubes can be transported away by the conveyor belt 40, so that the ice cubes can be prevented from falling onto the track.

[0031] In order to reduce labor costs, such as Figure 1 and Figure 3 As shown, in this embodiment, the tunnel disaster warning method further includes the following steps: Step S60: a gravity sensor is provided at a predetermined position outside the tunnel 10, and the weight information can be transmitted to the controller through the gravity sensor; Step S70: the controller issues a transport instruction according to the weight information, and the operator transports the ice cubes at the predetermined position according to the transport instruction. The above steps reduce the labor consumption, and the operator only needs to wait until the ice cubes reach the preset weight before transporting them, which can effectively reduce the labor cost.

[0032] In order to ensure the safety of train operation, Figure 1 and Figure 3 As shown, in this embodiment, step S80 is further included between step S40 and step S50: the controller transmits the start information of the heating plate 30 and the conveyor belt 40 to the train, and the train decelerates to pass through the tunnel 10 according to the start information. The above steps can further include the running safety of the train. Since the position where the ice cubes fall on the conveyor belt 40 cannot be accurately calculated, the train needs to decelerate to enter the tunnel when deicing is performed. Specifically, when deicing is performed in the tunnel 10, the train starts to decelerate when the distance from the tunnel 10 is 10 km, and needs to be reduced to 60% of the normal running speed when entering the tunnel 10.

[0033] In order to improve the accuracy of detection, Figure 1 and Figure 3 As shown, in this embodiment, the detection device includes an infrared thermal imaging detection device and a laser nondestructive testing device, and the infrared thermal imaging detection device and the laser nondestructive testing device simultaneously detect water seepage points in the tunnel 10. The above infrared thermal imaging detection device and the laser nondestructive testing device have good detection effects.

[0034] like Figure 1 and Figure 3As shown, in this embodiment, the heating plate 30 is arranged on the water seepage point of the side wall of the tunnel 10, and the conveyor belt 40 is located below the heating plate 30. The above arrangement can ensure the melting of the ice layer and enable the melted ice cubes to fall onto the conveyor belt 40 and be conveyed out by the conveyor belt 40.

[0035] To prevent interference, such as Figure 1 and Figure 3 As shown, in this embodiment, the conveyor belt 40 is arranged in close contact with the side wall of the tunnel 10, and the conveyor belt 40 is arranged along the length direction of the tunnel 10. The conveyor belt 40 is arranged in close contact with the side wall of the tunnel 10, which can effectively reduce the space occupied and avoid interference with other structures.

[0036] In order to save energy, Figure 1 and Figure 3 As shown, in this embodiment, the power of the heating plate 30 and the conveyor belt 40 is provided by solar energy and wind energy. The power of the heating plate 30 and the conveyor belt 40 is provided by solar energy and wind energy together, specifically by dual-circuit power supply, so that the heating plate and the conveyor belt can be continuously powered. Avoid the situation where there is no sun and the solar energy cannot supply power or there is no wind and the wind energy cannot supply power.

[0037] like Figure 1 and Figure 3 As shown, in this embodiment, a drainage ditch is provided at the bottom of the side wall of the tunnel 10. After the operation of step S41, the ice cubes melt into water and flow into the drainage ditch. The drainage ditch can collect water therein and discharge it through the drainage ditch.

[0038] like Figure 1 and Figure 3 As shown, in this embodiment, a heating device is arranged on the side wall of the drain ditch, and the temperature in the drain ditch is continuously maintained at a predetermined temperature. The above arrangement can prevent the water in the drain ditch from freezing, and ensure that the water in the drain ditch can continue to flow.

[0039] The technical solution of this embodiment determines the location and area of ​​the water seepage point by infrared thermal imaging and laser scanning nondestructive testing. The heating plate 30 and the sensor for measuring the thickness of the ice layer, i.e., the thickness detection sensor 20, are arranged and installed according to the area and location of the water seepage point. A number of thickness detection sensors 20 for measuring the ice layer are arranged in the icing area of ​​each water seepage point in the tunnel 10, and each tunnel 10 and each water seepage point in the tunnel 10 are numbered. At the same time, the thickness detection sensor 20 arranged at each water seepage point is numbered and annotated with mileage. When the thickness of the ice layer reaches a preset value, the thickness detection sensor 20 is triggered, and the thickness detection sensor 20 transmits the information to the controller. The controller can transmit data to the remote control center through wired data information transmission or wireless data information transmission. The remote control center automatically issues instructions to start the heating plate 30 and the conveyor belt 40 to heat and melt the ice. The ice melts at the place where it is in close contact with the tunnel wall, causing the ice to fall off the wall of the tunnel 10 and fall into the conveyor belt 40 installed on the wall of the tunnel 10 under the ice area. The conveyor belt 40 sends the ice to the ice collection area outside the tunnel 10; when the amount of ice accumulated in the ice collection area reaches the point where it needs to be cleared, the remote control center issues instructions to the work area work team, and after receiving the instructions, the work area work team arrives at the ice collection area outside the tunnel to remove the ice.

[0040] In the description of the present invention, it is necessary to understand that the directions or positional relationships indicated by directional words such as "front, back, up, down, left, right", "lateral, vertical, perpendicular, horizontal" and "top, bottom" are usually based on the directions or positional relationships shown in the drawings. They are only for the convenience of describing the present invention and simplifying the description. Unless otherwise specified, these directional words do not indicate or imply that the devices or elements referred to must have a specific direction or be constructed and operated in a specific direction. Therefore, they cannot be understood as limiting the scope of protection of the present invention. The directional words "inside and outside" refer to the inside and outside relative to the contours of each component itself.

[0041] For ease of description, spatially relative terms such as "above", "above", "on the upper surface of", "above", etc. may be used here to describe the spatial positional relationship between a device or feature and other devices or features as shown in the figure. It should be understood that spatially relative terms are intended to include different orientations of the device in use or operation in addition to the orientation described in the figure. For example, if the device in the accompanying drawings is inverted, the device described as "above other devices or structures" or "above other devices or structures" will be positioned as "below other devices or structures" or "below other devices or structures". Thus, the exemplary term "above" can include both "above" and "below". The device can also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatially relative descriptions used here are interpreted accordingly.

[0042] In addition, it should be noted that the use of terms such as "first" and "second" to limit components is only for the convenience of distinguishing the corresponding components. If not otherwise stated, the above terms have no special meaning and therefore cannot be understood as limiting the scope of protection of the present invention.

[0043] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
