Description

Safe isolation wall that charges

Technical Field

The utility model relates to a safety charging partition wall for when preventing that a plurality of electric automobile from charging side by side, the vehicle that takes place the accident on fire ignites adjacent vehicle.

Background

With the popularization of electric vehicles, when a plurality of electric vehicles are charged, after a fire is caused by a line or battery failure, an accident that an adjacent vehicle is ignited sometimes occurs.

SUMMERY OF THE UTILITY MODEL

To the above problem, the utility model aims at providing a technical solution, through the box that adopts double-deck tank wall with the combination of dry sand, realize that separation flame stretchs and cuts off the heat radiation to a certain extent, reach the purpose of avoiding the vehicle that catches fire to ignite adjacent vehicle.

The utility model comprises a base 0, a box body 1, a sealing cover 2 and a sealed door 3 (figure 1).

The base 0 is a rectangular structure, and the base 0 is made of rigid materials. The front end of the base 0 is provided with a universal wheel 11, and the rear end is provided with a directional wheel 12. The universal wheel 11 and the directional wheel 12 are used for moving the utility model.

The box body 1 is a hollow rectangular structure (figure 2), and the top of the box body 1 is provided with a circular sand injection port 8. The sealing cover 2 is arranged on the sand injection port 8 through a hinge device 7. The sealing cover 3 is of a circular structure, and the diameter of the sealing cover 3 is larger than that of the sand injection port 8.

The sand injection port 8 is used for injecting dry sand 9 into the box body 0.

The dry sand 9 has two functions: firstly, the heat insulation prevents heat from being transmitted through the utility model; secondly, fire extinguishing, namely isolating air by using dry sand and pressing open fire.

The sealing cover 3 is used for preventing rainwater, snow water or fog from entering the box body 0.

The front end of the box body 1 is provided with three sand outlets 13 (figure 2), and the sand outlets 13 are used for allowing the dry sand 9 in the box body 1 to flow out. The rotating shaft 4 is arranged on the same side of the sand outlet 13, and the L-shaped door bolt 5 is arranged on the rotating shaft 4.

The L-shaped bolt 5 has one end parallel to the wall of the tank in its installed position and the other end perpendicular to the wall of the tank in its installed position. The L-shaped bolt 5 can rotate around the axis of the rotating shaft 4 and parallel to the front wall of the box body 1.

The wall of the box body 0 has a double-layer structure (fig. 3) and is composed of an outer fireproof layer 14 and an inner framework layer 15. The fire-proof layer 14 is made of heat-insulating materials, and the framework layer 15 is made of high-strength metal materials.

Each sand outlet 13 is provided with a sealing door 3. The sealing door 3 is installed on the box body through a hinge device 7. The sealing door 3 is provided with a limiting block 6, which is used for preventing the L-shaped bolt from sliding downwards so as to close the sealing door 3.

The utility model discloses a three sand outlet 13 and three sealing door 3's effect is the outflow of dry sand 9 in for the convenience of controlling box 0. When the dry sand 9 is needed to extinguish a fire, the required quantity of the dry sand 9 can be judged according to the fire intensity.

When the amount of dry sand 9 required is small, the topmost sealing door 3 can be opened. When the dry sand amount is needed to be large, the sealing door 3 at the middle part or the bottom part can be opened.

Set up three sand outlet 13 and the sealing door 3 who matches with it, when having solved only one sand outlet 13, the dry sand 9 that once only flows out is too much, can't close sealing door 3 after using and pack the trouble of box 0 back into with too much dry sand 9.

Detailed Description

The following describes a specific embodiment of the present invention with reference to the drawings (fig. 1, fig. 2, fig. 3) of the present invention.

The sand injection port 8 is used for injecting dry sand 9 into the box body 0. The dry sand 9 serves the first purpose of insulating heat and the second purpose of extinguishing fire.

The sealing cover 3 is used for preventing rainwater, snow water or fog from entering the box body 0, keeping dry sand in a dry state and ensuring the flowability of the dry sand.

The front end of the box body 1 is provided with three sand outlets 13 (figure 2), and the sand outlets 13 are used for allowing the dry sand 9 in the box body 1 to flow out.

The rotating shaft 4 is arranged on the same side of the sand outlet 13, and the L-shaped door bolt 5 is arranged on the rotating shaft 4.

The L-shaped bolt 5 is perpendicular to one end of the box wall at the installation position, so that a stick or other objects can be conveniently used for pushing up the L-shaped bolt 5 and opening the sealing door 3.

Set up three sand outlet 13 and the sealing door 3 who matches with it, solved only when one sand outlet 13, the dry sand 9 that once only flows out is too much, can't close sealing door 3 and pack the trouble of box 0 back to with too much dry sand 9.

Use the utility model discloses the time, only need with the utility model discloses drag to the place of charging, place it between two adjacent vehicles. In case one of them car when catching fire because the utility model discloses a thermal-protective coating 14 and dry sand 9's existence can effectively play separation flame, separation thermal radiation's effect.

When fire is needed to be extinguished, the sealing door 3 is opened, the dry sand 9 in the sealing door is discharged, and the sealing door is covered on the flame.

Because the utility model discloses an existence of universal wheel 11, directional wheel 12, the utility model discloses the accessible is carried out, shift position. Because the hook 10, the universal wheel 11 and the directional wheel 12 exist, a vehicle can be used, and the utility model is very convenient to drag.
