Abstract

The spontaneous combustion prevention fire insulation plate comprises a fire insulation plate body, a first convex edge and a second convex edge, the first convex edge and the second convex edge are integrally formed on the left side wall and the right side wall of the fire insulation plate body, and a double-layer clamping plate structure is installed on the side, away from the fire insulation plate body, of the first convex edge and used for being connected with the second convex edge in an inserted mode. A neutral gear part used for allowing the second protruding edge to enter is arranged in the double-layer clamping plate structure, and positioning bolts are installed on the two sides of the top end of the double-layer clamping plate structure. When the second protruding edge is inserted into the double-layer clamping plate structure, the positioning bolt can effectively tighten the double-layer clamping plate, so that connection between the two fireproof plates is firmer, and compared with a traditional nail gun and connecting piece fixing mode, the connecting mode can remarkably improve the stability of the fireproof plates in the using process, and the service life of the fireproof plates is prolonged. And the problems of loosening, displacement or falling off caused by external force or long-term use are reduced.

Description

Technical Field

[0001] The invention relates to the technical field of fireproof boards, in particular to a fireproof board to prevent spontaneous combustion of an electric vehicle. Background Art

[0002] The fireproof board is a highly efficient fireproof safety material. Its main function is to isolate the fire source and delay the spread of fire, thereby protecting the lives and property of people. Its core functions include fireproofing and heat insulation, reducing thermal radiation, protecting building structures, reducing smoke diffusion, and buying time for rescue and fire fighting by delaying the spread of fire. The structure of the fireproof board is usually composed of a fire-resistant core material, a heat-insulating layer and a fire-resistant surface layer. Core materials such as gypsum, mineral wool and inorganic silicates have excellent high temperature resistance and can effectively block high temperature heat flow in a fire. The heat-insulating layer usually uses materials such as rock wool and glass wool, which have excellent thermal isolation effects and prevent the heat from the fire source from spreading to the surrounding environment. The external fire-resistant surface layer enhances the mechanical strength and durability of the fireproof board and improves its overall fire resistance. At present, during the construction of the electric vehicle charging shed, anti-spontaneous combustion fireproof boards are used to block the two sides of the charging pile to form a space area for charging a single electric vehicle. The left and right sides of the anti-spontaneous combustion fireproof boards are flat. During the continuous construction process, workers need to use nail guns and connectors to connect two adjacent anti-spontaneous combustion fireproof boards. Although the use of nail guns and connectors to connect anti-spontaneous combustion fireproof boards can improve construction efficiency, the fireproof boards connected by nail guns may gradually loosen or shift due to mechanical vibration, external force impact or environmental changes (such as temperature fluctuations) during use. Regular inspection and maintenance are required to ensure their stability. Over time, nails and connectors may rust, corrode or age, further reducing their connection effect. Summary of the invention

[0003] The purpose of the present invention is to provide an anti-spontaneous combustion fireproof board for electric vehicles, wherein a first convex edge and a second convex edge are respectively integrally formed on the left and right sides of the anti-spontaneous combustion fireproof board, and a double-layer plywood structure is hingedly installed on the first convex edge. When two anti-spontaneous combustion fireproof boards are docked, the second convex edge is inserted into the double-layer plywood structure, and the positioning bolt is used to tighten the double-layer plywood structure to tightly clamp the second convex edge, so that the two anti-spontaneous combustion fireproof boards can be docked, thereby solving the problems raised in the above-mentioned background technology.

[0004] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: an anti-spontaneous combustion fireproof board for electric vehicles, comprising a fireproof board body and a first convex edge and a second convex edge integrally formed on the left and right side walls of the fireproof board body, a double-layer plywood structure is installed on the side of the first convex edge away from the fireproof board body, the double-layer plywood structure is used to be plugged into the second convex edge, a gap portion for the second convex edge to enter is arranged inside the double-layer plywood structure, positioning bolts are installed on both sides of the top of the double-layer plywood structure, and the positioning bolts are used to force the double-layer plywood structure to tighten and clamp the second convex edge.

[0005] Preferably, a rounded chamfered portion is provided on the outer wall of the first convex edge on the side away from the fire isolation board body.

[0006] Preferably, the double-layer plywood structure includes a long U-shaped lower frame fixed to the lower surface of the first convex edge and a long U-shaped upper frame arranged on the upper surface of the long U-shaped lower frame, both sides of the top of the long U-shaped lower frame are integrally formed with internal threaded bosses, and both sides of the interior of the long U-shaped upper frame are provided with countersunk holes concentric with the internal threaded bosses, and positioning bolts are installed inside the countersunk holes, and the threaded end of the positioning bolts extends to the interior of the internal threaded bosses.

[0007] Preferably, a rotating shaft is fixed inside the first flange, and both ends of the rotating shaft penetrate to the outside of the first flange.

[0008] Preferably, both sides of the top end of the long U-shaped lower frame are integrally formed with convex seats, and the top end of the convex seat is provided with a notch portion that is mutually engaged with the rotating shaft.

[0009] Preferably, the rotating shaft is made of alloy steel.

[0010] Compared with the prior art, the beneficial effects of the present invention are as follows: the anti-spontaneous combustion fireproof board of the electric vehicle is designed with an integrally formed first convex edge and a second convex edge on the left and right sides of the anti-spontaneous combustion fireproof board, so that the fireproof board can form a tighter and more stable connection by embedding and fastening when docking, especially when the second convex edge is plugged into the double-layer plywood structure, the positioning bolt can effectively tighten the double-layer plywood, so that the connection between the two fireproof boards is more firm. Compared with the traditional nail gun and connector fixing method, this connection method can significantly improve the stability of the fireproof board during use, reduce the problems of loosening, displacement or falling off caused by external force or long-term use, and due to the fastening effect of the plywood and the convex edge, even in a high-temperature fire environment, the connection point can remain tight and firm, thereby ensuring that the overall performance of the fireproof board is not affected;

[0011] When two fireproof boards are tightly connected through a double-layer plywood structure, the gap between the fireproof boards will be greatly reduced, and the fire source and heat flow cannot be transmitted through the gap. This can effectively improve the fire isolation effect and reduce the risk of fire spread. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0018] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0019] See also Figure 1-5 , an embodiment provided by the present invention: an anti-spontaneous combustion fireproof board for electric vehicles, comprising a fireproof board body 1 and a first convex edge 2 and a second convex edge 5 integrally formed on the left and right side walls of the fireproof board body 1, and a round chamfered portion is arranged on the outer wall of the first convex edge 2 away from the fireproof board body 1;

[0020] A double-layer plywood structure 3 is installed on one side of the first convex edge 2 away from the fireproof board body 1. The double-layer plywood structure 3 is used to be plugged with the second convex edge 5. A gap 4 for the second convex edge 5 to enter is provided inside the double-layer plywood structure 3. Positioning bolts 9 are installed on both sides of the top of the double-layer plywood structure 3. The positioning bolts 9 are used to force the double-layer plywood structure 3 to tighten and clamp the second convex edge 5.

[0021] The construction personnel only need to insert the second raised edge 5 into the double-layer plywood structure 3 and then tighten the positioning bolt 9 to complete the connection. The whole process is efficient and accurate, and has significant construction advantages compared with traditional nail guns or other mechanical connection methods.

[0022] The double-layer plywood structure 3 includes a long U-shaped lower frame 302 fixed to the lower surface of the first convex edge 2 and a long U-shaped upper frame 301 arranged on the upper surface of the long U-shaped lower frame 302. Both sides of the top of the long U-shaped lower frame 302 are integrally formed with internal threaded protrusions 8. Both sides of the interior of the long U-shaped upper frame 301 are provided with countersunk holes concentric with the internal threaded protrusions 8. Positioning bolts 9 are installed inside the countersunk holes. The threaded ends of the positioning bolts 9 extend to the inside of the internal threaded protrusions 8. The second convex edge 5 is plugged into the gap between the long U-shaped upper frame 301 and the long U-shaped lower frame 302. 4, the staff continuously screws the positioning bolt 9 with an electric screwdriver, so that the positioning bolt 9 penetrates into the internal threaded boss 8, and the positioning bolt 9 forces the long U-shaped upper frame 301 to approach the first convex edge 2 and the long U-shaped lower frame 302, until the long U-shaped lower frame 302 and the long U-shaped upper frame 301 are fastened to the second convex edge 5. The two-layer design of the long U-shaped upper frame 301 and the long U-shaped lower frame 302 can effectively disperse the pressure and ensure that there is no looseness or gap in the joints between the fireproof panels, thereby preventing the fire source or high-temperature heat flow from spreading through the joints;

[0023] A rotating shaft 6 is fixed inside the first flange 2, and both ends of the rotating shaft 6 penetrate the outside of the first flange 2. The rotating shaft 6 is made of alloy steel.

[0024] Both sides of the top of the long U-shaped lower frame 302 are integrally formed with a boss 7, and the top of the boss 7 is provided with a notch 701 that is mutually engaged with the shaft 6. When the connection between two adjacent fire isolation board bodies 1 is completed, the double-layer plywood structure 3 and the second raised edge 5 can be deflected around the shaft 6 through the boss 7, so that the two adjacent fire isolation board bodies 1 can be relatively deflected, which is convenient for the staff to adjust the layout direction of the fire isolation board bodies 1 according to the on-site construction requirements.

[0025] When the embodiment of the present application is used, first, at least two fire partition board bodies 1 with a first convex edge 2 and a second convex edge 5 need to be prepared. The left and right sides of the fire partition board body 1 have been integrally formed with convex edges. The staff places the two fire partition board bodies 1 at a predetermined position to ensure that the joints therebetween are aligned, that is, the operator needs to insert the second convex edge 5 of one fire partition board body 1 into the double-layer plywood structure 3 of the other fire partition board body 1. At this time, the space of the gap 4 of the double-layer plywood structure 3 is designed to match the shape of the second convex edge 5, so that it can accurately accept and tighten the plug-in. After the second convex edge 5 is inserted into the double-layer plywood structure 3, the next step is to further tighten the connection point through the tightening action of the positioning bolt 9, that is, by continuously screwing the positioning bolt 9, the interior of the gap 4 is tightened. The space is tightened to ensure that the double-layer plywood structure 3 can firmly clamp the second raised edge 5, so that the joint between the two fireproof boards achieves the best sealing effect. Once the positioning bolt 9 is locked, the double-layer plywood structure 3 will generate greater pressure due to the tightening force in the plywood, ensuring that the connection between the double-layer plywood structure 3 and the second raised edge 5 is tighter, thereby increasing the stability of the connection and effectively avoiding loose connections caused by external forces, temperature changes or vibrations. After completing the connection of the fireproof board body 1, the construction personnel check the joints to ensure that there are no obvious gaps or loose connections. If slight misalignment or looseness is found, the construction personnel can adjust the positioning bolt 9 again or reinforce the double-layer plywood structure 3 to ensure that the two fireproof boards are very tightly connected.
