[0002] With the development of the times and the progress of science and technology, mankind has entered an era of large-scale extraction and use of oil, and various petroleum products have penetrated into all areas of society.

[0003] Currently, a large number of tanker trucks transport oil on highways every day. Due to the special nature of oil, accidents during transport that cause tanker trucks to overturn, deform the tanks, and leak oil can easily lead to catastrophic accidents, seriously endangering public safety. Therefore, how to promptly and properly handle tanker truck overturning accidents and avoid secondary injuries caused by tank deformation and oil leaks has become one of the main subjects of daily training for firefighters. Conducting simulation training research on tanker truck overturning is of great significance for developing emergency response plans and rescue operations for major hazard sources.

[0004] Traditional tanker truck rollover simulation training typically involves lifting one side of the tanker truck and tipping it over along with the tank using a special platform or road section. However, this training method requires a special training location and can easily cause damage to the vehicle during the rollover process. Summary of the Invention

[0005] Therefore, it is necessary to provide a tank rollover simulation device and method for fire training that is not limited to the training location and does not cause damage to vehicles during the training process, in order to address the above-mentioned technical problems.

[0006] A tank tipping simulation device for fire training includes:

[0007] The tank body, installed on the tank truck, has corresponding through slots on both sides;

[0008] The main shaft is installed at the top of the inside of the tanker truck along the length of the tanker truck;

[0009] Four horizontal shafts, each horizontal shaft is perpendicular to the main shaft and is slidably installed at the bottom end of the main shaft. The two ends of each horizontal shaft face the through grooves on both sides of the tank body, and a vertical shaft is rotatably installed at each end of each horizontal shaft.

[0010] The ends of the horizontal and vertical axes can extend and retract in a straight line, and two horizontal axes are installed on both sides of the center of gravity of the main shaft.

[0011] In one embodiment, pneumatic clamps are respectively provided on the horizontal shaft and the main shaft, and the pneumatic clamps are used to fix the horizontal shaft and the main shaft on the tank body.

[0012] In one embodiment, the top of the tank is provided with a plurality of pulleys along its length, and the tank and the main shaft are slidably connected by the plurality of pulleys.

[0013] In one embodiment, the tank is provided with a plurality of support columns, which are perpendicular to the bottom surface of the tank and are evenly distributed at the bottom end of the tank.

[0014] In one embodiment, the tank also has two cover plates that are rotatably mounted on the top of the through slot.

[0015] In one embodiment, the vertical height of the vertical axis is less than the vertical height of the horizontal axis.

[0016] In one embodiment, the horizontal axis and the vertical axis are rotatably connected by a rotary motor, and the maximum rotation angle of the rotary motor is 180°.

[0017] In one embodiment, the ends of both the horizontal and vertical axes are hydraulic rods driven by a hydraulic pump.

[0018] In one embodiment, the shortest distance between the two ends of the vertical axis is less than the horizontal height of the tank.

[0019] A method for simulating tank rollover for fire training, the method comprising:

[0020] Two horizontal axes located on different sides of the spindle's center of gravity are designated as the first moving axes, and the remaining horizontal axes are designated as the second moving axes.

[0021] Extend both ends of all horizontal axes outward and out of the tank through slots;

[0022] Rotate the vertical shaft on the pilot shaft so that the vertical shaft on the pilot shaft is perpendicular to the ground, and extend the end of the vertical shaft on the pilot shaft downward until the tank is lifted;

[0026] Slide the main shaft to the target position along the length of the rear moving shaft;

[0027] The end of the vertical shaft on the retracted shaft is used to lower the tank to the ground and restore all horizontal and vertical shafts to their initial state.

[0028] The aforementioned tank rollover simulation device and method for fire training involves designating any two horizontal axes located on opposite sides of the main shaft's center of gravity as the first moving axes and the remaining horizontal axes as the second moving axes. The two ends of the horizontal axes are extended outwards through slots into the tank. The vertical axis on the first moving axis is rotated to be perpendicular to the ground, and the bottom end of the vertical axis on the first moving axis is extended downwards until the tank is lifted. The main shaft is then slid along the length of the first moving axis, moving the tank to its maximum distance. The vertical axis on the second moving axis is rotated, and the above steps are repeated until the tank moves with the main shaft to the preset target position. The bottom end of the vertical axis currently lifting the tank is then retracted upwards, lowering the tank to the ground. Finally, all horizontal and vertical axes are retracted, thus simulating the tank rollover of the tanker truck. This device only moves the tank on the tanker truck during fire training to simulate the tank's tipping over, without damaging the tanker truck or the tank itself. Furthermore, the device is not limited by special sites or environments and does not require other auxiliary equipment. Training can begin in any open space, thus improving the simulation effect of fire training. Attached Figure Description

[0040] The following is combined Figures 1-3 The present invention describes a tank rollover simulation device and method for fire training.

[0041] like Figure 1 and Figure 2 As shown, in one embodiment, a tank tipping simulation device for fire training includes a tank 100, a main shaft 200, and four horizontal shafts 300. The tank 100 is mounted on a tank truck and has corresponding through slots 120 on both sides, meaning the through slots 120 on both sides of the tank 100 are at the same horizontal height and are symmetrical about the center plane of the tank 100 along its length. The main shaft 200 is mounted at the top of the tank 100 along the length of the tank truck, generally on the symmetrical center line of the tank 100. The horizontal shafts 300 are perpendicular to the main shaft 200 and are slidably mounted at the bottom of the main shaft 200. Both ends of all the horizontal shafts 300 face the through slots 120 on both sides of the tank 100, and each horizontal shaft 300 has a vertical shaft 400 rotatably mounted at both ends. The ends of the horizontal shafts 300 and the vertical shafts 400 can extend and retract in a straight line. Two horizontal shafts 300 are mounted on both sides of the center of gravity of the main shaft 200.

[0042] It should be noted that during use, any two horizontal axes 300 located on different sides of the center of gravity of the main shaft 200 can be considered to move synchronously, and the other two horizontal axes 300 can also be considered to move synchronously. Depending on the weight of the tank 100, multiple horizontal axes 300 can be added on different sides of the center of gravity of the main shaft 200 to improve the stability of the device during operation.

[0043] The aforementioned tank rollover simulation device for fire training uses two horizontal axes 300 located on opposite sides of the center of gravity of the main shaft 200 as the first moving axes, and the remaining horizontal axes 300 as the second moving axes. The two ends of the horizontal axes 300 are extended outwards, extending out of the tank 100 through the through slot 120. The vertical axis 400 on the first moving axis is rotated to be perpendicular to the ground. Then, the bottom end of the vertical axis 400 on the first moving axis is extended downwards until the tank 100 is lifted. The main shaft 200 is then slid along the length of the first moving axis, moving the tank 100 to its limit distance. The vertical axis 400 on the second moving axis is rotated and the above steps are repeated until the tank 100 moves with the main shaft 200 to the preset target position. The bottom end of the vertical axis 400 that is currently lifting the tank 100 is then retracted upwards, and the tank 100 is placed on the ground. Finally, all the horizontal axes 300 and vertical axes 400 are retracted, thus simulating the rollover of the tanker truck 100. During fire training, this device only moves the tank 100 on the tanker truck to simulate the side tipping of the tank 100, without causing damage to the tanker truck or the tank 100. Furthermore, the device is not limited to special sites or environments and does not require other auxiliary equipment. Training can be started in any open space, which improves the simulation effect of fire training.

[0044] In this embodiment, pneumatic clamps 500 are respectively provided on the horizontal axis 300 and the main axis 200. The pneumatic clamps 500 are used to fix the horizontal axis 300 and the main axis 200 on the tank body 100. Specifically, the pneumatic clamps 500 are clamps that use compressed air pressure to position and clamp the workpiece. The pneumatic clamps 500 are used to fix the horizontal axis 300 and the main axis 200 relative to the tank body 100 to prevent unnecessary slippage during transportation and training. Turning off the pneumatic clamps 500 allows the main axis 200 or the tank body 100 to be moved when needed, which is convenient and quick.

[0045] It should be noted that before the training begins, during the process of the tanker truck moving to the training site and during the displacement of the tank body 100, that is, during the process of the ends of the four horizontal shafts 300 extending outward and the vertical shaft 400 rotating and extending downward, the pneumatic clamp 500 remains open. The main shaft 200 is fixed to the top of the tank body 100 through the pneumatic clamp 500, and the horizontal shafts 300 are fixed to the bottom of the main shaft 200 through the pneumatic clamp 500. When the vertical shaft 400 touches the ground and lifts the tank body 100, the horizontal shaft 300 to which the vertical shaft 400 belongs becomes the support shaft of the current tank body 100. The pneumatic clamp 500 fixing the support shaft is closed, releasing the fixed relationship between the tank body 100 and the support shaft, so that the main shaft 200 can drive the tank body 100 and the non-supporting horizontal shafts 300 to slide.

[0046] In this embodiment, multiple pulleys are provided at the top of the tank 100 along its length, and the tank 100 and the main shaft 200 are slidably connected via these pulleys. Specifically, the tank 100 and the main shaft 200 are slidably connected via trackless wheels, and the tank 100 and the main shaft 200 are fixed together by a pneumatic clamp 500 when necessary. After the tank 100 moves to the target position along the length of the horizontal axis 300, the pneumatic clamp 500 is turned off, and the tank 100 is slid along the length of the main shaft 200 according to the site conditions to move the tank 100 to the most suitable training position.

[0047] In this embodiment, the tank 100 is provided with multiple support columns, which are perpendicular to the bottom surface of the tank 100 and are evenly distributed at the bottom of the tank 100. Specifically, multiple support columns are provided at the bottom of the tank 100 to maintain the stability of the tank 100 when placed on the ground. Multiple support grooves can also be provided on the body of the tank truck. During the retraction of the tank 100, the support columns are aligned with the support grooves one by one, which facilitates quick and accurate positioning of the tank 100 and improves its stability.

[0048] In this embodiment, the tank 100 also has two cover plates, which are rotatably mounted on the top of the through groove 120. Specifically, during the process of the tank 100 moving to the target position, since the horizontal axis 300 needs to extend out of the tank 100, the cover plate is lifted by the horizontal axis 300. After the tank 100 moves to the target position, the position of the horizontal axis 300 is restored, so that the horizontal axis 300 is retracted into the tank 100. At this time, the cover plate naturally falls down to cover the through groove 120, so as to restore the shape of the tank 100 as much as possible in the actual situation during the training process.

[0049] In this embodiment, the vertical height of the vertical axis 400 is less than the vertical height of the horizontal axis 300. Specifically, the vertical axis 400 is rotatably mounted at the bottom end of the horizontal axis 300, and during rotation, the vertical axis 400 is always lower than the vertical height of the horizontal axis 300.

[0050] In this embodiment, the horizontal axis 300 and the vertical axis 400 are rotatably connected by a rotary motor, and the maximum rotation angle of the rotary motor is 180°.

[0051] In this embodiment, the ends of both the horizontal axis 300 and the vertical axis 400 are hydraulic rods driven by hydraulic pumps.

[0052] Specifically, the device can be powered by an electric motor and controlled by a control unit to achieve automated simulation. For example, tank trucks used in fire training can be equipped with corresponding control cabinets, hydraulic pumps, air compressors, vision cameras, pressure sensors, and infrared distance sensors. The control cabinet houses a built-in programmable logic controller (PLC) for controlling the opening, closing, and operation of the aforementioned equipment. The control cabinet is connected to a motor, providing centralized power to the device. One end of the hydraulic press is connected to the control cabinet, and the other end is connected to the horizontal axis 300 and the vertical axis 400 respectively, receiving signals from the control cabinet to control the extension and retraction of the ends of the horizontal axis 300 and the vertical axis 400. One end of the air compressor is connected to the control cabinet, and the other end is connected to the pneumatic clamp 500 on the tank 100 to control the switching of the pneumatic clamp 500. A rotary motor connects to the vertical axis 400 and the horizontal axis 300 and is electrically connected to the control cabinet, receiving signals from the control cabinet to change the angle between the vertical axis 400 and the horizontal axis 300. A vision camera with a built-in judgment algorithm is installed at the bottom of the tank 100 to determine whether the area below the tank 100 is sufficiently flat when the tank 100 is placed. Pressure sensors and infrared distance detectors are located at the bottom of the tank 100 and the end of the vertical axis 400 furthest from the horizontal axis 300, used to determine whether the tank is in contact with the ground or the tanker truck body.

[0053] The above-mentioned device can automate the simulation of a tanker truck tipping over 100mm in fire training. The specific operation is as follows:

[0054] The motor switch is activated, sending a command to the programmable logic controller (PLC) inside the control cabinet: The air compressor is controlled to close the pneumatic clamps 500 on the tank 100, releasing the tank 100 from the tank truck; the hydraulic pump controls the two ends of the horizontal shaft 300 to extend outwards, extending through the through-slot 120 out of the tank 100 to its maximum distance; the rotary motor is controlled to rotate the vertical shafts 400 on the two horizontal shafts 300 located on different sides of the main shaft 200 until they are perpendicular to the ground, and the bottom of the vertical shafts 400 is controlled to extend downwards via the hydraulic pump. At this point, the two horizontal shafts 300 mentioned above are the first moving shafts, and the other two horizontal shafts 300 are the second moving shafts; the control cabinet receives signals from the pressure sensor and the infrared distance detector, determines the distance between the bottom of the vertical shaft 400 on the first moving shaft and the ground, and after the bottom of the vertical shaft 400 on the first moving shaft touches the ground, it controls the vertical shaft on the first moving shaft to extend downwards. The bottom end of shaft 400 continues to extend downwards until it supports the tank 100; the pneumatic clamp 500 used to fix the pilot shaft is closed by the air compressor to release the fixed relationship between the tank 100 and the pilot shaft; the main shaft 200 is slid along the length of the pilot shaft to move the tank 100 to the farthest distance; the air compressor, hydraulic pump and rotary motor are controlled in sequence to extend the vertical shaft 400 on the rear shaft to the ground to support the tank 100; the air compressor is controlled to close the pneumatic clamp 500 on the rear shaft to release the fixed relationship between the tank 100 and the rear shaft, and the air compressor, hydraulic pump and rotary motor are controlled in sequence to restore the pilot shaft to its initial state and restore the fixed relationship with the tank 100; the main shaft 200 is slid again along the length of the rear shaft (direction unchanged) to move the tank 100 to the farthest distance; the above operation is repeated until the tank 100 moves to the target position. At this time, the bottom of the vertical axis 400 supporting the current tank 100 is slowly retracted by the hydraulic pump. During this process, the vision camera, pressure sensor and infrared distance sensor at the bottom of the tank 100 continue to work and send the acquired signals to the control cabinet until the tank 100 touches the ground. The air compressor, hydraulic pump and rotary motor are controlled in sequence to restore all the horizontal axis 300 and vertical axis 400 to their initial state and restore their fixed relationship with the tank 100, thus completing the side-tipping simulation of the tank 100.

[0055] If training is terminated due to special circumstances, the following steps can be used to move tank 100 back onto the tank truck:

[0056] The motor switch is turned on to activate the device, and a command is sent to the programmable logic controller (PLC) inside the control cabinet: the air compressor is controlled to close the pneumatic clamp 500 on the tank 100 to release the fixed relationship between the tank 100 and the tank truck; the air compressor, hydraulic pump, and rotary motor are controlled in sequence to extend the bottom end of the vertical shaft 400 on the pilot shaft to the ground, thereby supporting the tank 100; the vision camera acquires its own position information relative to the tank truck and sends it to the control cabinet, which moves the main shaft 200 according to the position information, thereby driving the tank 100. The device 100 moves towards the vehicle body. During the movement, the vision camera continuously updates the position information. When it detects that the distance between the two is less than half the length of the horizontal axis 300, the infrared distance sensors on the tank body 100 and the vertical axis 400 detect the distance between the device and the tank truck, and gradually move it onto the tank truck. Through the vision camera, the support columns at the bottom of the tank body 100 are aligned with the support grooves on the tank truck, and the bottom end of the vertical axis 400 used for support is slowly retracted, restoring the device to its initial state and completing the recovery of the tank body 100.

[0057] like Figure 3 As shown, in one embodiment, a tank rollover simulation method for fire training includes the following steps:

[0058] Step S310: Select two horizontal axes located on different sides of the spindle's center of gravity and designate them as the first moving axes, and designate the remaining horizontal axes as the second moving axes.

[0059] In step S320, extend both ends of all horizontal axes outward and out of the tank through the through slots.

[0060] Step S330: Rotate the vertical shaft on the pilot shaft so that the vertical shaft on the pilot shaft is perpendicular to the ground, and extend the end of the vertical shaft on the pilot shaft downward until the tank is lifted.

[0061] Step S340: Slide the main shaft to its limit distance along the length direction of the pilot shaft.

[0062] Step S350: Rotate the vertical shaft on the rear moving shaft so that the vertical shaft on the rear moving shaft is perpendicular to the ground, and extend the end of the vertical shaft on the rear moving shaft downward until the tank is lifted.

[0063] In step S360, retract the end of the vertical shaft on the pilot shaft and rotate it until it is parallel to the ground.

[0064] Step S370: Slide the main shaft to the target position along the length direction of the rear moving shaft.

[0065] Step S380: Retract the end of the vertical shaft on the rear moving shaft to place the tank on the ground and restore all horizontal and vertical shafts to their initial state.

[0066] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0067] The embodiments described above are merely illustrative of several implementations of the present invention, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements all fall within the scope of protection of the present invention.
