Description

Technology Field

[0001] The present invention relates to an electric vehicle charging and firefighting system in the event of a fire in a multi-unit building, and more specifically, to an improved electric vehicle charging and firefighting system in the event of a fire in an underground parking lot or a charging area installed in the parking lot of a multi-unit building, wherein, by using a suffocating firefighting blanket installed directly above the parked electric vehicle and a firefighting water installed on the floor to perform a combination of suffocating firefighting and water spraying firefighting operations in a very short time, the firefighting efficiency is increased and the fire can be suppressed in a short time. Background Technology

[0002] Recently, the number of people using electric vehicles is increasing.

[0003] In addition, the production of internal combustion engine vehicles is being announced globally.

[0004] These electric vehicles are equipped with large-capacity batteries and operate using electricity stored in the batteries.

[0005] However, since the batteries of these electric vehicles are charged with a large amount of electricity, a fire may occur in the event of an accident or malfunction.

[0006] Also, these batteries generate intense heat in the event of a fire.

[0007] Therefore, if a fire occurs in an electric vehicle, the fire can easily spread to the surroundings, and a problem has arisen where smoke or soot generated during the fire can cause damage to nearby vehicles.

[0008] In particular, electric vehicles use lithium-ion batteries, which make it very difficult to extinguish fires when they occur.

[0009] In other words, since this battery, which is kept sealed, cannot extinguish a fire without a gap forming inside, in some cases it may burn for almost a whole day.

[0010] Therefore, various types of fire suppression tools have been developed, and as part of this, suffocating fire extinguishing blankets such as those described in the prior art literature can be cited.

[0011] However, it is practically impossible to approach a fire scene with an electric vehicle amidst high heat and flames and apply a suffocating fire extinguisher.

[0012] Therefore, a systemic configuration is required to effectively handle and suppress this situation. Prior art literature

Effects of the invention

[0017] According to the present invention, in the event of a fire occurring in an underground parking lot or a charging area installed in a multi-unit building, a combination of suffocation extinguishing and water spraying extinguishing is carried out in a very short time using a suffocation extinguishing cloth installed directly above a parked electric vehicle and extinguishing water installed on the floor, thereby increasing extinguishing efficiency and achieving an improved effect of suppressing the fire in a short time. Brief explanation of the drawing

[0018] FIG. 1 is an exemplary configuration diagram showing an electric vehicle charging and firefighting system in the event of a fire in a multi-unit residential building according to the present invention. FIG. 2 is an exemplary diagram of a floor discharge nozzle constituting a system according to the present invention. Specific details for implementing the invention

[0019] Hereinafter, preferred embodiments according to the present invention will be described in more detail with reference to the attached drawings.

[0020] As illustrated in FIG. 1, the electric vehicle charging and firefighting system for a multi-unit building according to the present invention includes a suffocating fire extinguishing blanket dropping unit (100).

[0021] The above-mentioned suffocation fire extinguishing blanket dropping unit (100) includes four pillars (110) that are vertically erected and fixed at the four corners of the electric vehicle charging area.

[0022] At this time, each upper end of the above column (110) has a bent extension (112) that is vertically bent in a direction facing each other.

[0023] The above-mentioned bending extension (112) is a part that performs a very important function, forming a hinge part that can drop the suffocation fire extinguishing blanket, and at the same time, is a means to guide the suffocation fire extinguishing blanket to be accurately set in the center.

[0024] That is, a vertical hinge bracket (120) is fixed to each lower surface of the above-mentioned bending extension (112), and a horizontal hinge bracket (122) is hinge-fixed to the lower surface of the above-mentioned vertical hinge bracket (120).

[0025] And, a suffocating fire extinguisher (130) is placed on the upper surface of the horizontal hinge bracket (122).

[0026] The above-mentioned suffocation extinguishing cloth (130) is an elastic square cloth that is open only at the bottom, and the perimeter sides have folds (132) formed to provide elasticity.

[0027] Therefore, when stored in a state where it is placed on a horizontal hinge bracket (122), it does not take up much installation space because it is folded due to the corrugated portion (132).

[0028] Then, when it falls downward, the corrugated portion (132) unfolds and completely seals the electric vehicle (AT), thereby suffocating the inside of the electric vehicle (AT) and suppressing the fire.

[0029] In addition, a fixed rod (140) is supported on the lower surface of the horizontal hinge bracket (122).

[0030] Therefore, since the horizontal hinge bracket (122) is supported by the fixed rod (140), it cannot rotate downward and maintains a horizontal fixed state, thereby supporting the suffocation fire extinguisher (130).

[0031] And, the fixed rod (140) is connected to the fixed cylinder (142).

[0032] The above fixed cylinder (142) is a means for moving the above fixed rod (140) while being driven by hydraulic, pneumatic, or linear motors.

[0033] In particular, the above fixed cylinder (142) is installed by penetrating each column (110) and is fixed by a support (144) on the outer side of each column (110).

[0034] Accordingly, when a fire occurs, the fixed cylinder (142) operates to retract the fixed rod (140), and the horizontal hinge bracket (122) loses its supporting means and is instantly rotated by its own weight and aligned in the vertical direction. At the same time, the suffocating fire extinguishing cloth (130), from which the supporting force has been removed, falls vertically downward and simultaneously wraps around the electric vehicle (AT) and completely seals it.

[0035] Here, a controller (150) is installed on one of the columns (110) to drive the above-mentioned suffocation fire extinguishing blanket dropping unit (100), and the controller (150) controls the driving of the above-mentioned fixed cylinder (142) based on a fire control signal received from a control server (not shown).

[0036] Additionally, the above column (110) is further equipped with a spray nozzle (160) that sprays fire extinguishing water toward the electric vehicle (AT) at a position higher than the electric vehicle (AT).

[0037] The above spray nozzle (160) is fixed to the nozzle body (162), and a fire extinguishing water pipe (164) is connected to the nozzle body (162). An opening / closing valve for controlling the opening of the fire extinguishing water pipe is built inside the nozzle body (162), and the opening / closing valve is controlled by the controller (150).

[0038] In addition, the vertical hinge bracket (120) and the horizontal hinge bracket (122) are coated on the surface with a coating composition mixed with 15 parts by weight of 2,4-dihydroxy-butanoic acid, 10 parts by weight of monocarboaluminate, 10 parts by weight of sodium ethyl 2-sulfolaurate, 5 parts by weight of 2-phenylimidazole, 10 parts by weight of dibutyl adipate, and 5 parts by weight of phosphite ester, based on 100 parts by weight of polyurethane resin, in order to ensure water resistance, corrosion resistance, and anti-contamination properties.

[0039] At this time, 2,4-dihydroxy-butanoic acid is a substance corresponding to CAS number 1518-62-3, which prevents the reduction of pores due to adsorption between particles when mixed, thereby strengthening anchoring characteristics and enhancing durability.

[0040] In addition, monocarboaluminate prevents cracking and shrinkage, thereby increasing durability, water resistance, and water pressure resistance.

[0041] In addition, sodium ethyl 2-sulfolaurate is a substance corresponding to CAS No. 7381-01-3, and its molecular formula is C 14 H29 It is NaO5S and enhances stain resistance and corrosion resistance.

[0042] In addition, 2-phenylimidazole inhibits cracking by reducing drying shrinkage.

[0043] In addition, dibutyl adipate is a substance corresponding to CAS No. 105-99-7, which increases the flexibility of the resin and forms a surface film after coating, contributing to increased resistance to discoloration, hardening, and heat resistance due to UV blocking and oxidation prevention.

[0044] In addition, phosphite ester contributes to increasing the resistance to corrosion caused by chlorine components, thereby preventing crack resistance.

[0045] Meanwhile, in the present invention, as shown in the example of FIG. 2, a plurality of floor discharge nozzles (200) are installed at intervals along the length direction in the center of the width of the electric vehicle charging area.

[0046] At this time, the floor discharge nozzle (200) is embedded in the nozzle housing (210), the lower end of the floor discharge nozzle (200) is fixed by a fixing block (220), both sides of the fixing block (220) are caught by a binding rod (230), and the binding rod (230) is configured to extend and retract by a binding rod cylinder (240).

[0047] Accordingly, the floor discharge nozzle (200) is configured such that, in normal circumstances, only a portion of the upper part is exposed, allowing the fire extinguishing water supplied through the fire extinguishing resin pipe (250) to be discharged upward.

[0048] Of course, since it is a natural configuration in that an opening / closing valve (not shown) is provided and configured to be controlled by a controller (150) so that fire extinguishing water is not sprayed normally but only in an emergency, a detailed description is omitted.

[0049] Additionally, a discharge spring (260) is provided at the bottom of the floor discharge nozzle (200) to enable the floor discharge nozzle (200) to discharge, and this discharge spring (260) is embedded in the lower part of the nozzle housing (210).

[0050] At this time, the fire extinguishing resin pipe (250) should be connected in the form of a flexible corrugated pipe so as to adapt to the coming and going of the floor discharge nozzle (200).

[0051] Thus, when the control signal of the controller (150) is dropped in the event of a fire, the binding rod cylinder (240) operates to retract the binding rod (230), and since the means for fixing the fixing block (220) disappears, the floor discharge nozzle (200) rapidly rises together with the fixing block (220) by the elastic force of the discharge spring (260) and moves to the lower part of the electric vehicle (AT), that is, the position closest to the battery, so that it can spray fire extinguishing water.

[0052] In this case, it is better to configure the system so that a drill is provided downward from the electric vehicle (AT) at the point where the floor discharge nozzle (200) is located, so that the drill can make a hole in the battery and spray fire extinguishing water through the hole.

[0053] By doing this, digestion efficiency can be rapidly improved. Explanation of the symbols
