Description
Technical Field
[0001] This utility model relates to the field of rescue simulation devices, and in particular to a multi-scenario simulation device in a confined space. Background Technology
[0002] The Confined Space Intelligent Training Experience System is a safety training product designed to address the challenges of confined space training and insufficient worker safety awareness. The hardware component realistically recreates the interior of a confined space in a container manufacturing facility, comprising three core modules: a learning classroom, knowledge assessment, and simulation training. The learning classroom uses text, images, and 3D models to help users understand confined space knowledge; the knowledge assessment reinforces key concepts; and the simulation training includes "operational procedure simulation" and "emergency rescue drills."
[0003] One of the emergency rescue drills requires placing a dummy to be rescued into a tank, and then rescuers use a rescue rope to pull the dummy out. Traditional rescue methods have certain drawbacks and can affect rescue efficiency.
[0004] First, the dummy is located inside the tank. When using a rescue rope to rescue the dummy, one end of the rescue rope needs to be tied to the dummy. However, in traditional rescue operations, due to the large drop inside the tank, it is troublesome for rescuers to enter the tank and tie the rescue rope, which leads to wasted time and affects rescue efficiency.
[0005] Meanwhile, emergency rescue drills simulate real-world rescue scenarios, so the dummies are generally quite heavy. When using only a rescue rope to pull them, it is easy to encounter situations where they cannot be pulled, making the rescue more difficult.
[0006] To address this issue, a multi-scenario simulation device in a confined space is proposed. Utility Model Content

The rescue mechanism includes an extension component and a positioning component. A support component is set on the upper surface of the support platform 1.
[0036] Reference Figure 3 - Figure 5The extension component includes a ladder fixing section 61, a ladder extension section 62 that is slidably connected through the left surface of the ladder fixing section 61, a fixing plate 63 that is fixedly connected to the left surface of the ladder fixing section 61, the ladder extension section 62 that is located above the fixing plate 63, a pivot 64 that is slidably connected through the front surface of the fixing plate 63, a stop block 65 that is fixedly connected to the right surface of the pivot 64, a circular groove 601 that is formed in the inner wall of the support platform 1, an arc groove 602 that is formed in the inner wall of the support platform 1, the pivot 64 and the stop block 65 that are respectively engaged with the circular groove 601 and the arc groove 602, the arc groove 602 that is formed in an arc shape, and the stop block 65 that can move along the trajectory of the arc groove 602 and can only rotate 90 degrees.
[0037] Reference Figure 3 - Figure 5 The positioning component includes a positioning block 73. The inner wall of the ladder extension section 62 is elastically connected to a locking block 72 by a compression spring 71. A limiting groove 701 is opened at the right end of the bottom inner wall of the ladder fixing section 61, and a locking groove 702 is opened at the left end of the bottom inner wall of the ladder fixing section 61. The locking block 72 fits into the locking groove 702 and the limiting groove 701. A pull rope 74 is fixed to the right end of the ladder extension section 62 to facilitate pulling the ladder extension section 62 and retracting the ladder extension section 62 into the ladder fixing section 61 for storage.
[0038] Reference Figure 1 - Figure 2 The support assembly includes a mounting groove 501, on the inner wall of which a tripod 51 is installed. The tripod 51 is existing technology and can be implemented by those skilled in the art. As it is existing technology, it will not be described in detail in this case. The rescue rope can be tied to the tripod 51 to facilitate rescue work. A pulley system can be installed on the top of the tripod 51 to facilitate the hoisting of the dummy. The mounting groove 501 is opened on the upper surface of the support platform 1.
[0039] Reference Figure 3 - Figure 5 The rotating shaft 64 is rotatably connected to the inner wall of the circular groove 601, and the stop block 65 is slidably connected to the inner wall of the arc groove 602. The circular groove 601 and the arc groove 602 are connected, and the rotating shaft 64 can rotate ninety degrees along the inside of the circular groove 601.
[0040] Reference Figure 3 - Figure 5The positioning block 73 is slidably connected to the upper surface of the ladder fixing section 61 and slides longitudinally. The positioning block 73 is located inside the limiting groove 701. The positioning block 73 is L-shaped. A pull ring is fixedly connected to the upper surface of the positioning block 73 for easy pulling. One end of the compression spring 71 is fixedly connected to the upper surface of the locking block 72. The other end of the compression spring 71 is fixedly connected to the inner wall of the top of the ladder extension section 62. The locking block 72 is slidably connected to the lower surface of the ladder extension section 62. When the locking block 72 moves upward, it will squeeze the compression spring 71 to generate a reaction force. The locking block 72 is inserted into the inner wall of the limiting groove 701 and the inner wall of the slot 702. The right end of the lower surface of the locking block 72 is set as an inclined surface. When the inclined surface of the locking block 72 is squeezed, the locking block 72 will move upward and retract into the ladder extension section 62 to release the obstruction.
[0041] Working principle: When using this device, first climb up the support platform 1 to observe the state and position of the rescued dummy in the tank 4 through the circular through slot. Then, the ladder fixed section 61 is erected. During the erection process, the rotating shaft 64 will move along the trajectory of the arc groove 602 and drive the ladder extension section 62 to be vertical.
[0042] At this time, pulling the ring will move the positioning block 73. The moving positioning block 73 will squeeze the locking block 72, causing the locking block 72 to retract into the ladder extension section 62 and disengage from the limiting groove 701, thus releasing the limiting. During the movement, the locking block 72 will also squeeze the compression spring 71 to generate a reaction force. After the limiting is released, the ladder extension section 62 will slide downwards due to its own weight. When the ladder extension section 62 slides to the lowest point, the locking block 72 will align with the locking groove 702. The reaction force of the compression spring 71 will push the locking block 72 and the locking groove 702 to insert and form a limiting, ensuring the stability of the device. Then, the rescuers will climb into the tank 4 along the trajectory of the ladder fixed section 61 and the ladder extension section 62. During the climbing process, the ladder fixed section 61 and the ladder extension section 62 will maintain a vertical state under the influence of gravity. During the climbing process, other rescuers can also hold the ladder fixed section 61 to ensure stability.
[0043] Workers entering tank 4 can tie one end of the rescue rope to the waist of the rescued dummy, and then climb up to the support platform 1 along the trajectory of the ladder fixed section 61 and the ladder extension section 62. During the climb, they can carry one end of the pull rope 74. After the rescuers reach the support platform 1, they can pull the pull rope 74 upwards to move the ladder extension section 62 upwards. When the ladder extension section 62 moves upwards, the inclined surface of the locking block 72 will be squeezed, and the locking block 72 will retract into the ladder extension section 62 and disengage from the locking groove 702 to release the limit. The locking block 72 will also squeeze the compression spring 71 to generate a reaction force. When the ladder extension section 62 moves to the highest point, the compression spring 71 will push the locking block 72 and the limiting groove 701 to engage and limit the ladder extension section 62. Then, the ladder fixed section 61 can be laid flat.
[0044] Then, the other end of the rescue rope is fixed to tripod 51 to facilitate pulling up the dummy and making the rescue easier.
[0045] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model.
