[0002] Various types of transportation vehicles are prone to various accidents during operation, such as fire. If a fire occurs suddenly, it will be very difficult for people on the vehicle to escape and perform various operations. Therefore, it is necessary to collect relevant data during fire simulation tests to determine the best escape plan after the accident.

[0031] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0032] In order to better describe and illustrate the embodiments of the present application, reference may be made to one or more drawings, but the additional details or examples used to describe the drawings should not be considered as limiting the scope of the invention of the present application, any of the currently described embodiments or preferred methods.

[0033] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art to which this application pertains. The terms used herein in the specification of this application are for the purpose of describing specific embodiments only and are not intended to limit this application.

[0034] like Figures 1 to 3As shown, an assembled combustion tray includes a combustion tray module 1, a sealing gasket 2, and a fastener 3. The combustion tray module adopts a standardized design. Each combustion tray module 1 has a storage space surrounded by a bottom wall and side walls, and its side walls partially constitute a connecting portion. Several standardized combustion tray modules 1 are assembled in a matrix arrangement. The side walls of adjacent combustion tray modules 1 are close to each other. A longitudinal gap is defined between the side walls of adjacent columns of combustion tray modules 1, and a transverse gap is defined between the side walls of adjacent rows of combustion tray modules. The sealing gasket 2 is clamped between the longitudinal and transverse gaps. The fastener 3 connects to the two adjacent connecting portions to prevent separation of adjacent combustion tray modules 1 and clamp the corresponding sealing gasket 3.

[0035] A method of assembly implementation, adjacent combustion disk modules 1 can be assembled by bolts, the connection part of the combustion disk module and the sealing gasket have assembly holes adapted to the position, when assembling, the assembly holes of the adjacent combustion disk modules and the sealing gasket are aligned, and then bolts are used to pass through the assembly holes for fastening.

[0036] As a preferred design method for bolts, see Figure 3 , comprising a nut 31 and a screw 32, wherein the head of the screw 32 is threadedly engaged with the nut 31, and the tail of the screw 32 is provided with an eccentric wheel handle 34 that is rotatably engaged with the screw 31, and the rotation axis of the eccentric wheel handle 34 is perpendicular to the axis of the screw 31. Specifically, this can be achieved in the following manner: a shaft 35 whose axis is perpendicular to the axis of the screw is fixed to the tail end of the screw, and the eccentric wheel handle 34 comprises an eccentric wheel portion and a handle portion, wherein the eccentric wheel portion is rotatably mounted on the shaft 35.

[0037] The screw is passed through the assembly hole, a nut is put on and manually adjusted, and then the eccentric wheel handle is turned to quickly lock it using the eccentric wheel principle. Furthermore, a gasket 33 is movably inserted into the tail of the screw and located on the inner side of the eccentric wheel handle. The screw is sequentially passed through the gasket and the assembly hole, the nut is manually screwed on, and then the handle is turned to lock it using the eccentric wheel. In the locked state, the gasket abuts the outer wall of the corresponding connecting part on one side and the eccentric wheel part of the eccentric wheel handle on the other side.

[0038] A single combustion disk is configured as a cube or rectangular structure with four side walls. As an implementation of the connection portion of the combustion disk module, each side wall is thickened and heightened, and a portion of each side wall is used as the connection portion, for example, the upper half of the side wall is used as the connection portion.

[0039] Furthermore, according to the position of each combustion disk module after assembly, the combustion disk module can also be designed as a corner standard module 11, a side standard module 12 and a middle standard module 13. The corner standard module 11 refers to the combustion disk module located at the four corners after assembly. Since it is located at the four corners, only two adjacent side walls need to be spliced with other combustion disks. Therefore, for the corner standard module, only two adjacent connecting parts are provided with assembly holes. The side standard module 12 refers to the standard module located at the four sides after assembly. Here, three sides of the standard module need to be assembled with other standard modules. Therefore, for the side standard module, assembly holes are provided on three connecting parts. The middle standard module 13 refers to the standard module located in the middle after assembly. All four sides of the standard module are involved in the assembly. Therefore, assembly holes are provided on the four connecting parts of the middle standard module. Figure 4 The figure shows a schematic diagram of a corner standard module 11, which has a bottom wall 11a and four side walls 11b. The upper halves of the four side walls serve as connecting portions 11c, with assembly holes 11d provided in two adjacent connecting portions. Aside from the arrangement of the assembly holes, the center and side standard modules are identical to the corner standard modules.

[0040] The sealing gasket 2 is made of asbestos rubber, and the thickness of the sealing gasket is preferably 3 to 10 mm. Furthermore, the sealing gasket can also be set as a standardized structure. For example, in one embodiment, the sealing gasket can be set as a grid structure that is interwoven vertically and horizontally, and the grid size of the grid structure is adapted to the size of the standardized combustion disk module. During assembly, the sealing gasket of the grid structure is just embedded in the transverse gap and the longitudinal gap as described above, and then the adjacent combustion disk modules are locked by fasteners and the sealing gasket is clamped in the corresponding gap. In another embodiment, the sealing gasket can be set as a standardized strip structure, including a transverse sealing strip and a longitudinal sealing strip, the transverse sealing strip is clamped in the transverse gap as described above, and the longitudinal sealing strip is clamped in the longitudinal gap as described above, and the transverse sealing strip and the longitudinal sealing strip both have avoidance openings at their vertical and horizontal intersections, and the avoidance openings are used to achieve the vertical and horizontal intersection connection of the transverse sealing strip and the longitudinal sealing strip.

[0041] The area of a single combustion disk module can be designed according to actual needs, for example, it can be set to 0.25m 2 , in order to control the weight and facilitate the movement; the height of the side wall can be set at 100 ~ 500mm to adapt to different working conditions. Figure 1 Assemble in the arrangement shown.

[0042] The technical features of the above-mentioned embodiments can be combined arbitrarily. In order to make the description concise, not all possible combinations of the technical features in the above-mentioned 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.

[0043] The above-described embodiments merely represent several implementation methods of the present application. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that a person skilled in the art could make various modifications and improvements without departing from the spirit of the present application, all of which fall within the scope of protection of the present application. Therefore, the scope of protection of the present patent application shall be determined by the appended claims.
