Field of Invention
[0001] The present invention relates to a disaster rescue training facility, in particular a narrow space rescue training device in the form of a three-dimensional grid framework.
Background of invention
[0002] Fire and earthquake-induced collapse of buildings, along with the occasional mine collapses and other disasters have caused unnecessary casualties due to poor rescue conditions. Relevant government departments now realise the importance of fire fighters' rescue ability, thus gradually customising training facilities, such as bringing in the likes of narrow space rescue training, introducing smoke and heat training rooms, and increasing training to improve fire fighters' rescue abilities to train them to adapt to various harsh environments experienced in rescue missions.

As shown in Figure 16, holes 46 are provided for on the top and bottom surfaces of both ends of the square metal pipe 40. Holes 47 are also provided for on the side surfaces of the square metal pipes 40. With screws going through the holes 46, 47 and threaded holes on the plug portions of the multidirectional connector's pin plugs, the horizontal and erect frame pipes 40 can be connected tightly to these multidirectional connectors.
[0045] The execution of the narrow space rescue training device 1 according to the present invention is depicted in a schematic diagram shown in Figure 1. As shown in Figure 1, the device includes a three dimensional grid framework, multiple barriers, multiple metal meshes and passages, etc. set up in or between the framework's space units 70. As shown in Figure 1, the rescue training device is a five-level structured three-dimensional grid framework, constructed by using Figure 2's two-level structure's three dimensional framework's construction method. This three dimensional space rescue device 1 has 6 plates 10-60 configured in layers. Every plate contains a plurality of multidirectional connectors disposed in rows and columns of equally spaced distances. For the same row of two adjacent multidirectional connectors, the horizontal frame pipes are plug connected in between. For the same column of two adjacent multidirectional connectors, the horizontal frame pipes are also plug connected in between. An erect frame pipe 40 is plug connected between two multidirectional connectors that are disposed in two adjacent plates or layers. Four adjacent erect frame pipes 40 between two adjacent plates form a space unit 70. The above multidirectional connectors have multiple pin plugs, such that two adjacent pin plugs are substantially perpendicular to each other. It is preferable to use connectors depicted in Figures 3-5 for the top level three directional connector 1 1, top level four directional connector 13 and top level five directional connector 15 in plate 10. It is preferable to use connectors depicted in Figures 6-8 for the middle level four directional connector 21, middle level five directional connector 23 and middle level six directional connector 25 in plate 20. It is preferble to use connectors depicted in Figures 9-11 for the bottom level three directional connector 61, bottom level four directional connector 63 and bottom level five directional connector 65 in plate 60.
[0046] According to training requirements, barriers or obstacles can be chosen from ladder, manhole plate, tunnels, ramps, stairs, panels, round mouth plate, square mouth plate, rectangular mouth plate, a door plate, two door panels, diagonal opening board, and so on. Training modules can be constructed by setting up the chosen barriers/obstacles in or between space units 70. For the wall surface that has no barriers in the training modules, metal mesh are used to close it off (for clarity of illustration, metal meshes not shown in schematic diagram 1). For example, in Figure 1, a ladder 81 is shown in the left front corner linking the space units 70 at levels 1 -3. As examples, a manhole plate 82 is disposed in the space unit at level 4; around mouth plate 83 is disposed in space units at level 5; a tunnel 84 is disposed in the third space unit to the right of the of the round mouth plate 83 at level 5; a square mouth plate 86 is disposed at the right back corner space unit at the 5th level; a ramp 85 is disposed in a space unit at level 4; a ladder board 87 is disposed in a space unit in level 3; and a ramp 89 and another tunnel 88 are disposed in space units in the bottommost floor, forming different types of obstacles for training.
[0047] Various space units or training modules are connected by channels. The bases of the channels are covered with floor boards, whilst the channel's side walls may be formed with metal mesh plates. It is preferable to use mesh and barrier plates with hooks. The use of mesh or barrier plates with hooks for hanging in the opening of the space units of this framework to form wall surfaces makes it easy to re-configure a training module. With the use of metal mesh plates to form the outer walls of the training module, it becomes easier to rescue trainees who feel unwell during training, thus improving on the personal safety of trainees.
[0048] Also, training difficulty can be increased by creating simulated environments, for example, the traditional darkness, fog, high temperature and noise, and so on. Thus, under various kinds of harsh environments, trainers can teach trainees identify directions under physical and mental stress, as in a real rescue mission. At the same time, the trainees learn to control their breathing in different simulated environments. [0049] The three-dimensional grid framework according to the present invention is

;plates;;lthesh plates iand<'^ It is easy to install, easy to disassemble and reassemble, easy to: disassemble and reassemble into frameworks of different shapes. With the present invention it is easy to re-configure new training devices according to varying training requirements.
[0050] The examples of executional use described above serve only to illustrate the use of the present invention. These examples of executional use and description should not limit the scope; of the present invention. Many changes in design without departing from the principle of the present invention are possible but they are considered to fall within the scope of the present invention as defined in the claims.
