Description
Technical Field
[0001] The utility model relates to the technical field of facilities for fire training, in particular to a simulated pipe gallery collapse device for firefighter training. Background Art
[0002] In the construction of real fire simulation training scenes for firefighters, it is necessary to restore the complex environment of the fire accident scene as realistically as possible. Especially when constructing fire scenes with pipe gallery layouts such as chemical and related factories, it is necessary to consider the simulation and restoration of accident phenomena such as the collapse of the pipe gallery due to complex factors that affect the stability of the shelf structure, such as direct contact with flames and continuous high temperature.
[0003] In the existing construction of such scenes, most of them use fixed simulated pipe gallery structures to achieve simple scene reproduction. Such scene construction has the disadvantages of fixed scenes, simple training plans, and single training paths. As a result, it can only simply restore the composition of material elements at the accident scene, but cannot simulate and construct secondary disaster scenes caused by fire and high temperature of material elements.
[0004] Therefore, there is still a real need to build a simulated training scene of a real fire for firefighters to further enhance their resilience and ability to handle fire accidents in dangerous and complex environments. In order to better meet the needs of scene construction, when simulating fires in scenes with pipe corridors such as chemical and related factories, a pipe corridor collapse device can be set up to simulate the collapse disaster scene of the pipe corridor caused by fire and high temperature, and restore the fire accident scene more realistically. The pipe corridor collapse device can be connected to the automatic control system, with automatic reset function, automatic assessment function, realize the position signal transmission, and can also realize the transformation of the size of the traversable space of the training path.
[0005] The pipe gallery collapse device can provide firefighters with a more realistic, safe and reliable prop for constructing training scenarios during real fire simulation training. Utility Model Content

[0021] The technical solutions in the embodiments of the present utility model are clearly and completely described below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present utility model, rather than all the embodiments.
[0022] See also Figure 1-3 The utility model discloses a simulated pipe gallery collapse device for firefighter training, which can solve the problem of providing simulated pipe gallery collapse for firefighter real fire simulation training during firefighter real fire training.
[0023] like Figure 1 As shown, the simulated pipe gallery collapse device for firefighter training includes two columns 100, and the top of each column 100 is provided with a connecting portion 101 extending toward the other column 100, and each connecting portion 101 is hinged with an extension body 200, and one end of the extension body 200 extends toward the opposite column 100. A driving device 300 is provided between the column 100 and the extension body 200, and the driving device 300 controls the extension body 200 to swing up and down.
[0024] The utility model of the simulated pipe gallery collapse device for firefighter training uses an extension body 200 to simulate a pipe gallery in real fire training for firefighters. The pipe gallery is supported by columns 100. Generally, the extension bodies 200 on two columns 100 are horizontally relatively simulated to simulate a complete and intact pipe gallery. When it is necessary to simulate the collapse of the pipe gallery, the driving device 300 controls the extension body 200 to swing downward to simulate the effect of the collapse of the pipe gallery. After the training is completed, the driving device 300 controls the extension body 200 to swing upward to restore to a horizontal posture.
[0025] The column 100 is used for fixing and supporting the whole structure, in order to support the function of the device and realize structural optimization, such as Figure 2As shown, a hinge hole 102 is provided at one end of the connection portion 101 away from the column 100, a hinge ear 201 is provided on the lower side of the end of the extension body 200 close to the column 100, and the hinge ear 201 is hinged to the hinge hole 102. The driving device 300 is a reciprocating telescope, one end of the reciprocating telescope is hinged to the lower part of the column 100, and the other end is hinged to the lower side of the end of the extension body 200, and is hinged on the side of the hinge ear 201 away from the column 100 on the opposite side.
[0026] Generally, the reciprocating telescopic device is a hydraulic cylinder.
[0027] like Figure 2 As shown, a limiting plate 103 is disposed on the connecting portion 101 , and when the extension body 200 extends horizontally, the lower side of the end of the extension body 200 close to one end of the column 100 abuts against the limiting plate 103 .
[0028] refer to Figure 1 When working, the reciprocating telescope extends and pushes the end of the extension body 200 close to the column 100 onto the stage to drive the end away from the column 100 to swing downward. After completion, the reciprocating telescope retracts and returns to its original position. After completion, the extension body 200 is in a horizontal state. At this time, the limit plate 103 can limit and position the end of the extender.
[0029] Further, refer to Figure 2 The first proximity switch 400 and the second proximity switch 500 are arranged on the connecting part 101. The first proximity switch 400 is arranged near the hinge where the extension body 200 and the connecting part 101 are hinged, and is used to detect the lower limit position of the downward swing of the extension body 200. The second proximity switch 500 is arranged near the end direction of the column 100, and is used to detect whether the extension body 200 is in a horizontal extension state. When training, the current posture of the extension body 200 can be determined by the detection of the first proximity switch 400 and the second proximity switch 500, and whether it is in a horizontal intact state or a collapsed and damaged state.
[0030] Furthermore, considering the complex situation at the real fire training site and preventing the occurrence of uncontrollable factors, the extension body 200 includes a coaxially fixedly connected metal tube 202 and a PVC tube 203, the metal tube 202 is arranged at one end in the direction adjacent to the column 100, the lower side of the metal tube 202 is provided with a hinge ear 201 for the hinged connection part 101, and the PVC tube 203 is arranged at one end of the metal tube 202 away from the column 100. This can prevent the firefighters from being injured by contact with the extension body 200 during the training. The PVC tube 203 is preferably a lightweight PVC tube 203, so that when the extension body 200 of the PVC tube 203 section touches the firefighter, the PVC tube 203 can be relatively deformed or broken to avoid harmful pressure on the firefighter.
[0031] like Figure 1 As shown, a cutout 204 is provided at one end of the PVC pipe 203 away from the metal pipe 202, and when the two extension bodies are horizontal, the cutouts 204 of the two PVC pipes 203 are staggered and overlapped. In this way, when the extension bodies 200 are horizontal, the two extension bodies 200 are more like a complete pipe gallery from a sensory point of view.
[0032] refer to Figure 3 The driving device 300 is controlled by PLC, and personnel position sensing sensors for determining personnel positions are arranged around the driving device 300. The first proximity switch 400 and the second proximity switch 500 are connected to the PLC to form a control system, and the control system is connected to the fire assessment system to form a simulation system for assessment.
[0033] When working, the system is started, and the personnel position sensing sensor is used to determine whether the firefighters have entered the disposal area. After the personnel enter the disposal area, the driver is activated, and the device begins to simulate collapse. After the collapse reaches the set maximum limit (detected and determined by the first proximity switch 400), the driving device 300 stops and maintains the current state. Through the set personnel position sensing sensor, it is further determined that after the personnel leave the set assessment judgment area, or after the entire assessment process is completed, when there is no one in the detection area, the driving device 300 is controlled to control the extension body 200 to return to the horizontal state. The collapse disposal is completed.
[0034] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
