New energy vehicles are prone to battery pack fire and spontaneous combustion under conditions such as battery thermal runaway, battery immersion, and thermal management effectiveness during charging. After the new energy vehicle spontaneously combusts, the fire burns fiercely, spreads from the battery compartment at the bottom of the vehicle to the outside, and it is difficult to control the fire in a short time. In public places such as underground parking lots or open-air parking lots, due to the dense parking of vehicles, when the vehicle spontaneously combusts, the fire will quickly spread to the surrounding vehicles, and if not handled in time, it will cause serious property damage.

DETAILED DESCRIPTION

[0025] The specific embodiments of the utility model will be further described in combination with the drawings:

[0026] As Figure 1 shown, a movable fire baffle for new energy vehicles is composed of a vertical plane frame 1, a movable fire baffle 2 installed on the plane frame 1 and moving supports 3 installed on both ends of the bottom of the plane frame. The movable fire baffle is used for fire isolation of new energy vehicles in spontaneous combustion, and two movable fire baffles are generally used in combination to isolate the vehicle in spontaneous combustion from adjacent vehicles.

[0027] The plane frame 1 is a rectangular frame formed by welding four circular tubes, and reinforcing rods can be welded in the rectangular frame to strengthen the structure. The four circular tubes of the plane frame 1 are connected to form a fire-fighting water channel, and a fire-fighting pipe joint 4 is connected to one of the circular tubes of the plane frame 1. Spray heads 5 are installed at equal intervals on the four circular tubes to realize spray cooling while isolating fire. The plane frame 2 can also be composed of angle steels or square tubes and other metal pieces, and a ring of fireproof pipes is installed on the inner side of the angle steel. Spray heads are installed at equal intervals on the fireproof pipes, and the fireproof pipes are connected to a fire-fighting joint. The spray heads on the vertical pipes on both sides of the plane frame 2 face the horizontal direction, the spray heads on the upper horizontal pipe face downward and outward, and the spray heads on the lower horizontal pipe face the horizontal direction. After the fire-fighting water is connected, the vertical pipes form a vertical water curtain to reduce the temperature of the smoke emitted, the upper horizontal pipe sprays water to cool the burning vehicle and the adjacent vehicle, and the bottom horizontal pipe cools the flame to delay the spread of the fire.

[0028] Sliding grooves 6 are installed on the front side of the two vertical pipes of the plane frame 2, and a movable fire baffle 2 is installed between the sliding grooves 6. The movable fire baffle 2 is a fireproof plate, preferably a double-layer metal plate structure with fireproof cotton. The height of the movable fire baffle 2 is more than half the height of the plane frame 1, and the movable fire baffle 2 moves vertically along the sliding grooves 6 in the plane frame 1. The bottom of the sliding groove 6 is open. The movable fire baffle 2 can slide along the sliding groove 6 and directly contact the bottom surface, so that the flame can be prevented from spreading outward from the gap at the bottom.

[0029] The movable fire baffle 2 is limited in the plane frame by the limiting structure, which is a spring pin 7 installed in a pair of sliding grooves, or a fuse type pull rope 8, or a combination of the spring pin 7 and the fuse type pull rope 8. When the fuse type pull rope 8 is selected as the limiting structure, two fuse type pull ropes 8 are fixedly connected to the top of the movable fire baffle 2 on both sides, respectively, and the fuse type pull ropes 8 pass over the upper cross beam of the plane frame 1 and are connected with the moving support 3 at the bottom of the plane frame. The connection mode is a lock type connection or a buckle type connection. When the fire baffle is pushed to the fire point, the flame melts the pull rope, and the movable fire baffle 2 freely falls to form isolation. When the spring pin is selected as the limiting structure, after the fire baffle is pushed to the fire point, the spring pin 7 is released, and the movable fire baffle 2 freely falls to form isolation.

[0030] Since the ignition point of the new energy vehicle is located at the battery compartment at the bottom of the vehicle, the flame is generally concentrated below the middle of the vehicle, so the movable fire baffle 2 can isolate most of the flame. In order to improve the isolation effect, a fixed fire baffle 9 can be provided on the plane frame, the fixed fire baffle 9 is welded to the inner side of the plane frame 1 and located at the middle upper part of the plane frame 1, the movable fire baffle 2 is overlapped with the fixed fire baffle 9 in the limited state, and after the limiting is released, the movable fire baffle 2 slides upward to the bottom to contact the ground, the upper part of the movable fire baffle 2 is partially overlapped with the fixed fire baffle 9, or the top surface of the movable fire baffle 2 is flush with the bottom surface of the fixed fire baffle 9.

[0031] The moving support 3 is preferably a tripod support 10, the top corner of the tripod 10 is connected with the bottom of the plane frame 1 through a rotating support 11, and a roller 12 is installed on each bottom foot of the tripod 10. When the gap between the vehicles is small, the tripod support can be rotated so that the two rollers 12 on the same side are coplanar with the plane frame 1, which facilitates pushing in. After the pushing in is completed, the tripod support is rotated so that the two rollers 12 on the same side are located on both sides of the plane frame 1, so that stable support can be achieved.

[0032] The technical solution is a plane fire baffle, which occupies a small space in parking lots, underground garages and the like, and can be placed against a wall. The fixed fire baffle and the movable fire baffle designed in the present application are overlapped in the folded state, so that the fire baffle of the present application can be used as a bulletin board or a propaganda column when stored, thereby increasing the use.

[0033] Since the length of the vehicle is generally about 4-5 meters, the fire baffle can adopt a folding structure, such as Figure 3As shown, it is composed of multiple parallel plane frames, the bottom of each plane frame is provided with a pair of moving supports, adjacent plane frames are movably connected through hinges 13, each plane frame is provided with at least one movable plate, the fire-fighting water pipes between adjacent plane frames are connected through corrugated hoses 14 to form passages.
