Description

Technical Field

[0001] The invention relates to the technical field of landslide and debris flow rescue team training, and in particular to a landslide and debris flow rescue training scene simulation device. Background Art

[0002] Landslide refers to the phenomenon that solid materials such as soil and rock layers slide down the slope as a whole or in a dispersed manner under the action of gravity under the influence of factors such as river scouring, rainfall, and earthquakes. Mudslide refers to a special torrent of solid materials such as mud, sand, and stones that is generated in valleys or hillsides under the action of surface water formed by precipitation and dam breaches. It has both soil and fluid properties. Landslides and mudslides mainly occur in areas with complex geological structures, steep terrain, and high earthquake intensity. They are characterized by suddenness, large flow, fast speed, and strong destructive power, and are very likely to cause heavy casualties and property losses.

[0003] In order to quickly, safely and effectively carry out post-disaster rescue and disposal, it is particularly important to improve the emergency rescue team's understanding of landslide and debris flow disasters, establish a complete rescue procedure, conduct professional and systematic training, and improve the technical level of emergency rescue forces. At present, training in an environment close to real landslide and debris flow disasters and carrying out actual combat exercises are important ways to improve rescue technology and cognition.

[0040] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present application: Specific embodiment 1:

[0042] In this embodiment, if Figure 1 As shown, the relative direction of the two foundation pit entrances 72 is the front-to-back direction, and the relative direction of the two sets of stone rolling training systems 40 is the left-to-right direction.

[0043] refer to Figures 1 to 6 The present invention provides a simulation device for landslide and debris flow rescue training scenarios (hereinafter referred to as the simulation device) including a foundation pit 70, on which a ruins training system 10, a sand surge training system 30, a stone rolling training system 40 and a recovery system are arranged.

[0044] The ruin training system 10 is used to conduct simulated ruin rescue training for trainees. The sand surge training system 30 is used to conduct wading training for trainees, simulating flood and sand surge rescue training. The sand surge training system 30 is also used to pour muddy water into the ruin training system 10 to simulate the debris flow and landslide process. The rolling stone training system 40 is used to inject light stone models 41 into the ruin training system 10 and the sand surge training system 30 to simulate the secondary disaster of rolling stones in the landslide and debris flow rescue process, so as to conduct emergency training for trainees. The recycling system is used to recycle muddy water and light stone models 41 for recycling.

[0045] In this way, the ruins training, sand surge training system 30, and stone rolling training system 40 are used to simulate various types of disasters encountered in the landslide and debris flow rescue process, and the whole process of landslide-induced debris flow disasters is carried out, and the whole process of emergency rescue and emergency rescue training is carried out. At the same time, the stone rolling training system 40 can be used to train the ability to deal with sudden accidents in emergency rescue and emergency rescue. In addition, the sand surge training system 30 can inject muddy water and sand and gravel into the ruins training system 10 before and during training, which can train the ability to deal with secondary disasters in the rescue process, realize the simulation of various rescue methods and rescue types, ensure the flexibility of simulation, improve the rescue training effect, and ensure that the actual training goals and requirements are met.

[0046] Specifically, in this embodiment, the foundation pit 70 is a sunken pit structure, which is surrounded by a protective structure 7. As a storage space for each system, it can be set above ground or underground, and a fence isolation zone is set outside the 10m range to protect the training facilities and prevent other people from entering by mistake. Slopes 71 are set around the inner side of the foundation pit 70, and foundation pit entrances 72 higher than the pit bottom are set on the front and back sides of the foundation pit 70, respectively, as the entrance of the simulation device. The ruins training system 10 includes a training structure 1 arranged in the middle of the pit bottom. The training structure 1 includes a collapsed floor 12, a connecting pipe 13 and at least two spaced structures 15.

[0047] In this embodiment, two groups of structures 15 are arranged at intervals along the left-right direction, and two structures 15 are arranged at intervals along the front-back direction in each group. The collapsed floor 12 is staggered between the two groups of structures 15 in the horizontal and vertical directions. The connecting pipes 13 connect the structures 15, and various types of rescue items are arranged in the structures 15.

[0048] Specifically, in this embodiment, the structure 15 is a multi-story building, including three floors above ground and one floor underground, with a floor height of 3.5-4.5m, and is a prefabricated concrete assembled structure. A training room is set up in each floor of the building, and adjacent floors are connected by internal stairs. At the same time, a longitudinal demolition floor is also set up in the structure 15 to increase obstacles and improve the simulation authenticity. Rescue projects are set up in the training room, and the rescue projects are to simulate the common disaster types in buildings in landslide and mudslide disasters.

[0049] In this embodiment, the pipe 13 is a square pipe or round pipe training facility. The pipe 13 has different internal height differences and is connected to connect the floors of adjacent structures 15 to achieve the series connection of the above-ground and underground spaces. A longitudinal opening is provided on the pipe 13 for rescuers to enter the pipe 13 and the corresponding structure 15. A climbing ladder is provided along the length of the pipe 13 as a climbing training facility for rescuers to move to different structures 15. When moving between different floors of a group of structures 15, rescuers can transfer through the pipe 13 or through the stairs in the structure 15, which improves diversity and flexibility and is more practical.

[0050] Preferably, in this embodiment, the recovery system includes a muddy water recovery system 60 and a rolling stone recovery system, wherein the muddy water recovery system 60 includes a sedimentation tank 61. Figure 4 As shown, the sand surge training system 30 includes an annular water pool 3 arranged on the periphery of the training structure 1 , the height of the annular water pool 3 is higher than the bottom of the foundation pit 70 and lower than the top of the structure 15 , and the sedimentation tank 61 is arranged below the water pool 3 .

[0051] The sand gushing training system 30 also includes a water supply device, which includes a gushing well 34 arranged in the water pool 3, a water supply pump room (not shown in the figure) arranged in the sedimentation tank 61, and a first water pipe connecting the gushing well 34 and the water supply pump room. A plurality of gushing wells 34 are arranged at intervals at the bottom of the water pool 3. In this way, the muddy water and sand in the sedimentation tank 61 are injected into the water pool 3 by using the water supply device.

[0052] The pool 3 is used as a simulated training area for floods and sand surges. The water supply pump room continuously injects muddy water and sand into the pool 3 to simulate the occurrence of muddy water and sand surges. The water depth, flow rate and gushing position can be set according to actual requirements. The staff conducts wading training before going to the ruins training system 10 to simulate the rescue scene of traveling in the flood.

[0053] Specifically, in the present embodiment, the simulation device further includes a folding plate system 20 for connecting the ruins training system 10 and the sand surge training system 30. The folding plate system 20 includes two folding plates 2 which are symmetrically arranged on the left and right. The opposite ends of the folding plates 2 are hinged ends, and the opposite ends extend to the bottom of the corresponding side pool 3. The hinge axis of the folding plate 2 extends in the front-to-back direction. The ruins training system 10 is arranged between the two folding plates 2, and further includes a flipping device, which is used to drive the two folding plates 2 to flip.

[0054] In this way, after wading training, the trainees can enter the ruin training system 10 through the folding plate 2 of the folding plate system 20. At the same time, the muddy water and sand in the sand surge training system 30 can be poured into the ruin training system 10 through the folding plate system 20 to simulate the landslide and mud-rock flow process.

[0055] Specifically, the turning device includes an electric hoist 25 and a steel cable 26. A plurality of electric hoists 25 are arranged at intervals along the front-to-back direction at the position corresponding to the folding plate 2 at the bottom of the pool 3. The steel cable 26 is connected between the corresponding electric hoist 25 and the folding plate 2. The electric hoist 25 cooperates with the steel cable 26 to realize the clockwise and counterclockwise rotation of the corresponding side folding plate 2.

[0056] Specifically, in this embodiment, if Figure 4 As shown, an opening and closing baffle 31 is provided on the side of the pool 3 facing the training structure 1. The opening and closing baffle 31 is opened and closed by an opening and closing device, and the muddy water and sand in the pool 3 flow to the folding plate 2 on the corresponding side through the opening and closing baffle 31. This arrangement can automatically control the pouring of muddy water and sand through the opening and closing device, which is more in line with the real scene. At the same time, when the rescue personnel conduct rescue training in the ruin training system 10, they can also inject muddy water and sand into the ruin training system 10 again through the opening and closing device to simulate secondary landslide and debris flow disasters, adjust the rescue difficulty, improve the response ability of rescue personnel in the face of secondary disasters and secondary disasters, and improve the effect of rescue training.

[0057] Specifically, the pool 3 is provided with an opening on one side facing the ruins training system 10, and an opening and closing gate 31 is blocked at the opening. The lower end of the opening and closing gate 31 is hinged to the lower end of the pool 3 through a hinge shaft 32 whose axis is in the front-to-back direction. The opening and closing device is a reset spring and a limit switch arranged between the opening and closing gate 31 and the pool 3, so that the opening and closing gate 31 constitutes a spring gate. When the water pressure in the pool 3 reaches the critical pressure value of the spring gate, the limit switch at the bottom of the spring gate is activated to release the blocking of the spring gate. The spring gate flips outward along the hinge shaft 32 to form a drain port, and the muddy water and sand in the pool 3 quickly pour into the folding plate system 20 to simulate the flow process of the debris flow. When the pouring is finished, the opening and closing gate 31 is reset under the action of the reset spring to continue to block the opening, and the limit switch is reset to continue to block the opening and closing gate 31 for fixing. The automatic pouring of muddy water and sand can be realized, the degree of automation is improved, and the suddenness of the debris flow disaster can be simulated at the same time.

[0058] In this embodiment, two opening and closing doors 31 are set on the sides of the left and right sides of the pool 3, and a ladder 36 is set between the two opening and closing doors 31. The bottom of the ladder 36 is connected to the folding plate 2. The ladder 36 is used for trainees to enter the folding plate system 20 from the pool 3.

A floor 14 is set in the middle of the bottom of the foundation pit 70, and the cross section of the floor 14 is a two-slope structure, which slopes toward the sedimentation tank 61. By turning the folding plate 2 downward, the muddy water and other media on it can enter the sedimentation tank 61 for recycling. By using the floor 14, the muddy water and sand and gravel at the bottom of the ruins training system 10 can enter the muddy water recovery system 60 through the floor 14 for recycling, so as to achieve full recycling of muddy water and gravel.

[0076] In this embodiment, the simulation device also includes a control system, which consists of a control panel, a main control switch, a training mode switch, a cleaning mode switch, a folding plate adjustment switch, a water injection switch, a sand surge switch, a sprinkler switch, a rolling stone gate switch, and a rolling stone monitoring device. Each switch is used to control the operation of the above-mentioned corresponding systems and corresponding components in the system respectively.

[0077] The implementation steps of the application example of the present invention are as follows:

[0078] 1. Preparation

[0079] 1. Entry: The commander and the training personnel enter the simulation device through the pit entrance 72 and stand by at the pit entrance 72, waiting for the mission command to be initiated.

[0080] 2. Start the system: The commander operates the control system, opens the control panel, clicks the main control switch and the training mode switch, the training device starts the power supply, then clicks the water injection switch, the sand surge switch and the spray switch, the mud and water recovery system 60 responds immediately, the vibrator 62 of the mud and water recovery system 60 mixes the mud and water through vibration, and the corresponding pump room sends the mixed material into the water pool 3 of the sand surge training system 30 and the spray water pipe 55 of the rainfall system.

[0081] 3. Adjust the spraying position: under the control of the driving device, the slider 52 on the top of the spray head 51 moves along the corresponding slide rail 53, while dragging the hose 57. When it reaches the target position, the mixed material flows from the spray water pipe 55 through the hose 57 into the spray head 51, and the spray head 51 starts to spray downward.

[0082] 4. Adjust the angle of the folding plate 2: Turn on the adjustment switch of the folding plate 2, and change the take-off and landing height of the folding plate 2 by driving the electric hoist 25 of the folding plate system 20 to simulate different terrain slopes and training difficulties.

[0083] 5. When, in the simulation device, under the action of the spray system 50 and the sand surge training system 30, the mud and water coverage height and the water injection depth of the pool 3 reach the requirements, the preparation stage ends and the simulation training begins.

[0084] (II) Training Mode

[0085] A. Landslide and debris flow disaster simulation

[0086] 6. The trainees immediately start the rescue drill and enter the pool 3 of the sand surge training system 30 from the foundation pit entrance 72. The gushing well 34 of the pool 3 continuously injects materials into the pool 3, gushing sand and muddy water, simulating the occurrence of muddy water and sand surge, and can set the water depth, flow rate and gushing position according to the task requirements. The trainees need to reach the designated location through the pool 3, and perform wading training on the way to simulate the rescue scene of marching in the flood.

[0087] 7. When the water pressure reaches the critical pressure value of the reset spring, the limit switch at the bottom of the opening and closing baffle 31 is opened, and the opening and closing baffle 31 rotates along the hinge shaft 32 to form a drain port. The muddy water in the pool 3 quickly pours out to the folding plate system 20, simulating the flow process of a debris flow. After the tilting is completed, the opening and closing baffle 31 is reset under the action of the reset spring, and muddy water continues to accumulate.

[0088] 8. In the specific step 7, the opening and closing baffle 31 is folded outward and overlapped to the edge of the folding plate 2 under the pressure of the water flow, and the opening and closing baffle 31 serves as a water bridging plate between the pool 3 and the folding plate 2 to prevent mud and water from leaking. The mixture of mud, water, sand and gravel pours into the training structure 1 and its surrounding areas, simulating the scene of the building being covered and swallowed by the debris flow landslide.

[0089] 9. At the same time, the trainees need to reach the designated position of the pool 3, that is, the ladder 36, within the specified time. The ladder 36 is located in the middle of the pool 3 and between the two opening and closing gates 31. It serves as a transportation facility for climbing over the pool 3 and entering the folding plate system 20. After the trainees reach the folding plate 2 via the ladder 36, they carry out rescue training exercises.

[0090] B. Secondary disaster simulation:

[0091] 10. The commander operates the control system and clicks the rolling stone gate switch. The rolling stone training system 40 responds, the gate 42 of the stone storage bin 4 opens, and the light stone models 41 pour out from the inside of the stone storage bin 4, along the retaining structure 7 through the slope 71 to reach the pool 3 or directly fall into the folding plate 2 platform. A part of the light stone models 41 rolls into the hollow structure 28 on the first floor of the training structure 1 along the slope direction of the folding plate 2 and enters the central area of ​​the training structure 1.

[0092] 11. The trainees need to enter the training structure 1 in advance at the specified time, select a safe area (pipeline 13 or upper structure), and find a suitable shelter to avoid the rolling stones. If the trainees are hit by the light stone model 41, the trainees will be eliminated, and the trainees who successfully avoid the rolling stones will continue to complete the rescue mission.

[0093] 12. The training structure 1 is provided with training facilities such as training rooms, stairs, pipes 13 and longitudinal demolition floors. The trainees enter the pipes 13, which have different internal height differences and are interconnected and connected to the above-ground and underground floors. The trainees climb along the ladder inside the pipes 13 and reach other floors through the longitudinal demolition openings for climbing training. Various types of rescue projects are arranged inside the training room, and different floors can be reached through the collapsed floor 12. The collapsed floor 12 is arranged between the two structures 15 and serves as a bridge connecting the structures 15, while the stairs are only used for evacuation in emergencies.

[0094] 13. According to the mission requirements, the commander can simulate the occurrence of landslides, mudslides and their secondary disasters for many times, and simulate rainfall conditions in severe weather by adjusting the positions and water pressure of the rainfall system sprinkler heads 51, changing the rainfall range and intensity, so as to allow the training personnel to conduct rescue training drills in different subjects, increase the frequency of training, and adapt to different types of training mission requirements.

[0095] 14. When the rescue training drill is completed, the trainees return to the foundation pit entrance 72 via the folding plate 2 and the pool 3, and the training ends.

[0096] (III) Cleaning mode

[0097] 15. The commander operates the control system and clicks the cleaning mode switch. The folding plate system 20 responds, and the electric hoist 25 releases the steel cable 26. The two plates of the folding plate 2 platform rotate clockwise and counterclockwise downward around the front and rear rotation shafts 22 respectively until the folding plate 2 touches the floor 14 and stops rotating.

[0098] 16. The mixed materials (mud, sand, and light stone model 41) on the folded plate 2 flow into the mud recovery system 60 along the inclined direction of the folded plate 2, which is composed of a filter screen 6, a sedimentation tank 61, and a vibrator 62 from top to bottom. The filter screen 6 is used to separate debris flow materials, including mud, sand, and light stone model 41. The aperture of the filter screen 6 is smaller than the diameter of the light stone model 41. The mud and sand flow along the filter screen 6 into the lower sedimentation tank 61, and the light stone model 41 passes through the filter screen 6 and rolls into the collection tank 43.

[0099] 17. Click the rolling stone recovery switch, the air duct system responds, the fan rotates and sucks the light stone mold 1 near the collection tank 43 into the air duct. At the same time, the impurities are separated from the air duct by the filter separator 47 and fall into the sedimentation tank 61, realizing the full process circulation of the mixed material.

[0100] 18. The light stone model 41 enters the stone storage bin 4 under the action of the fan. The stone storage bin 4 at the end of the air duct is first filled with the light stone model 41. A weight detector 46 is arranged inside the stone storage bin 4. When the weight detector 46 reaches the mass peak, the opening and closing valve 48 connected to the air duct is closed, and the light stone model 41 continues to fill the remaining stone storage bins 4.

[0101] In summary, the simulation device of the present invention can not only simulate the whole process of landslide and mudslide and multiple types of disaster scenarios, but also provide a simulation of primary disasters such as mudslide and its secondary disaster scenarios such as rolling stones. It can conduct independent one-time tests or continuous multi-frequency team drills according to requirements. At the same time, the device uses a folding plate system 20 to form a closed loop among the recovery system, sand surge training system 30 and rolling stone training system 40, so as to realize the recovery and recycling of materials, avoid waste, and reduce transportation costs, so as to study the evolution process, destruction forms and emergencies of landslide and mudslide disasters, organize and carry out learning and drills of relevant training subjects such as pre-handling, rescue during the event and post-event recovery of disaster emergency rescue training, and provide technical support for improving the level of emergency rescue.
