Technology Field

[0001] The present invention relates to a mobile vehicle fire suppression device, and more specifically, to a mobile vehicle fire suppression device that covers a vehicle on which a fire has occurred to extinguish the fire by suffocation. Background Technology

[0003] In general, an electric vehicle (hereinafter referred to as an "EV") is a vehicle that generates driving force by supplying electrical energy from a high-voltage battery to an electric motor; because it does not use fossil fuels, it is an eco-friendly vehicle with almost no exhaust gas emissions or noise.

[0004] The batteries mainly used in electric vehicles are lithium-ion batteries. If the separator that separates the cathode and anode, which are the main components of the battery, is damaged and the two electrodes come into contact, excessive current flows and heat is generated, which can lead to a fire.

[0005] Recently, the number of electric vehicle (EV) fires has been increasing due to the rising demand for EVs. Because EV fires spread horizontally, they cause significant damage.

[0006] When a fire occurs in an electric vehicle, battery thermal runaway occurs, and secondary damage accidents such as smoke spread and fires in adjacent vehicles are taking place, and preventive measures related to this are required.

[0007] As electric vehicle fires cause extended damage to surrounding vehicles, facilities, and buildings, significant efforts and urgent improvements are required to protect valuable lives and property.

[0008] For prior art, refer to Registered Patent No. 10-2503331 (February 21, 2023). The problem to be solved

[0010] The present invention aims to provide a mobile vehicle fire suppression device that is deployed in a vehicle where a fire has occurred, and allows a single person without protective equipment to easily suppress the fire as the fire extinguishing cloth is rapidly deployed, and can reduce secondary damage by preventing the spread of flames and the diffusion of harmful gases. means of solving the problem

[0012] A mobile vehicle fire suppression device according to the present invention comprises: a main frame positioned around a vehicle where a fire has occurred; a conveyor wheel provided on the lower side of the main frame to enable the main frame to move; and a fire extinguishing cloth module provided on the upper side of the main frame to selectively deploy a fire extinguishing cloth along the main frame, wherein the fire extinguishing cloth module comprises a fire extinguishing cloth that is selectively deployed to cover the main frame, a pair of winding rolls for winding the fire extinguishing cloth, and an actuator for controlling the movement of the winding rolls.

[0013] At this time, the main frame according to the present invention preferably comprises left and right frames that are symmetrical with respect to each other at a certain distance, and a connecting frame disposed between the left and right frames, with one end and the other end connected to the left and right frames, so that it is arranged in a 'U' shape when viewed from above.

[0014] In addition, the left and right frames according to the present invention form a hemispherical shape when viewed from the left and right directions, and a guide groove is formed on each upper surface.

[0015] delete

[0016] At this time, the pair of winding rolls according to the present invention can rotate forward and backward along the upper surfaces of the left and right frames, thereby allowing the wound fire extinguisher cloth to unfold.

[0017] In addition, the winding rolls according to the present invention can extend a rolling wheel, which is partially inserted into and guided by the guide groove, in the outer direction. Effects of the invention

[0019] The effects produced by the mobile vehicle fire suppression device according to the present invention are as follows.

[0020] After positioning the device at the fire vehicle (site), pressing the switch on the device activates it, and the suffocating fire extinguishing blanket fixed to the top of the device is rapidly deployed, allowing for safe and immediate fire suppression as well as preventing the spread of flames and harmful gases, thereby reducing secondary damage.

[0021] Due to the device's wide versatility, it can be applied not only to new buildings where the structure and facilities can be modified during construction, but also to existing buildings or small buildings where it is difficult to change the structure and systems.

[0022] It can effectively respond to vehicle fires because the operation method is simple enough for an ordinary person without protective equipment to extinguish the fire alone. Brief explanation of the drawing

Specific details for implementing the invention

[0025] Hereinafter, preferred embodiments according to the present invention will be described in detail with reference to the attached drawings. Prior to this, terms and words used in this specification and claims should not be interpreted as being limited to their ordinary or dictionary meanings, and should be interpreted in a meaning and concept consistent with the technical spirit of the present invention, based on the principle that the inventor can appropriately define the concept of the terms to best describe his invention.

[0026] Therefore, the embodiments described in this specification and the configurations illustrated in the drawings are merely the most preferred embodiments of the present invention and do not represent all of the technical ideas of the present invention; thus, it should be understood that there may be equivalent variations that can replace them at the time of filing this application.

[0027] The present invention relates to a mobile vehicle fire suppression device that is deployed in a vehicle where a fire has occurred, and allows a single person without protective equipment to easily suppress the fire by rapidly deploying a fire extinguishing cloth, and can reduce secondary damage by preventing the spread of flames and harmful gases. Referring to the drawings, the invention is as follows.

[0028] A mobile vehicle fire suppression device according to an embodiment of the present invention includes a main frame (100), a transport wheel (200), and a fire extinguishing gun module (300).

[0029] First, referring to FIGS. 1 to 4, the main frame (100) includes left and right frames (110, 120) respectively placed on the left and right sides of the vehicle, and a connecting frame (130) that connects the left and right frames (110, 120) at a certain distance.

[0030] At this time, it is preferable that each of the left and right frames (110, 120) have a length relatively longer than the front-to-rear length of the vehicle and a height relatively higher than the vertical height of the vehicle, so that the winding roll (320) on which the fire extinguisher (310) is wound moves downward along the inclined surface (the upper surface of the left and right frames (110, 120)).

[0031] And on the upper surface of each of the above left and right frames (110, 120), a guide groove (111, 121) is formed along its length to guide the winding roll (320) of the fire extinguisher module (300).

[0032] In addition, the inner sides of each of the left and right frames (110, 120) may be finished with a fire extinguishing cloth to prevent the spread of flames laterally.

[0033] The above left and right frames (110, 120) are symmetrically arranged at a certain distance from each other by means of a connecting frame (130) placed between them, so that a vehicle is accommodated between the left and right frames (110, 120).

[0034] The above connecting frame (130) consists of two parts, one positioned on the front side and the other positioned on the upper side.

[0035] One side of the connecting frame (130) positioned on the front side is connected to the front end of the left frame (110), and the other side of the connecting frame (130) is connected to the front end of the right frame (120). One side of the connecting frame (130) positioned on the upper side is connected to the top of the left frame (110), and the other side of the connecting frame (130) is connected to the top of the right frame (120).

[0036] Accordingly, the main frame (100) forms a 'U' shape when viewed from the vertical direction, and a space is formed between the left and right frames (110, 120) in which a vehicle can be accommodated, and a vehicle can enter the space through the open rear side.

[0037] And a conveyor wheel (200) is provided on the lower side of the main frame (100), and the conveyor wheel (200) is provided at each lower corner of the main frame (100) which forms a 'U' shape when viewed from the upper and lower directions, so that the main frame (100) can roll to move.

[0038] At this time, it is preferable that the transfer wheel (200) be provided to be rotatable around a connecting shaft so as to enable steering when the main frame (100) moves.

[0039] And a fire extinguishing gun module (300) is provided on the upper side of the main frame (100), and the fire extinguishing gun module (300) selectively deploys a fire extinguishing gun (310) along the front-rear length of the main frame (100).

[0040] The above fire extinguisher module (300) includes a fire extinguisher (310), a winding roll (320), and an actuator (330). The fire extinguisher (310) has a length corresponding to the front-rear length of the main frame (100) and has a width smaller than the width between the left and right frames (110, 120).

[0041] The above fire extinguishing cloth (310) is a flame-retardant cloth that is optionally deployed to cover a vehicle located between the left and right frames (110, 120) of the main frame (100) to prevent the spread of flames and harmful gases.

[0042] The fire extinguisher (310) is prepared in a state where it is wound on a winding roll (320), and when the winding roll (320) on which the fire extinguisher (310) is wound moves downward while rotating by load along the upper surface of the left and right frames (110, 120) by the operation of an actuator (330) provided on the upper side of the left and right frames (110, 120), the fire extinguisher (310) wound on the winding roll (320) unfolds to cover the main frame (100) and covers the vehicle located between the left and right frames (110, 120).

[0043] At this time, the winding rolls (320) are provided as a pair, with their lengths parallel to each other in the center of the main frame (100), so that one moves forward and the other moves backward, and the wound fire cloth (310) unfolds along the length of the main frame (100).

[0044] The above-mentioned winding roll (320) is preferably cylindrical in shape to facilitate winding and unfolding of the above-mentioned fire cloth (310), has a length in the left-right direction, and its length is arranged perpendicular to the length of the above-mentioned left and right frames (110, 120).

[0045] At this time, on the left and right sides of the above-mentioned winding rolls (320), a rolling wheel (321) is provided, which is partially inserted into and guided by the guide grooves (111, 121) of the left and right frames (110, 120), and a through hole (322) is formed on the outer side of the rolling wheel (321) along the length of the above-mentioned winding roll (320).

[0046] The above rolling wheel (321) allows the left and right sides of the winding rolls (320) to move in parallel when the winding rolls (320) rotate along the length of the left and right frames (110, 120), thereby facilitating the unfolding of the fire extinguisher (310).

[0047] A locking projection (331) of the actuator (330) is inserted into the through hole (322), thereby interrupting the rotation of the winding roll (320).

[0048] At this time, the locking projection (331) of the actuator (330) moves up and down in the vertical direction inside the actuator (330), and the locking projection (331) can move up and down by hydraulic or pneumatic pressure inside the actuator (330).

[0049] Accordingly, the locking projection (331) of the actuator (330) is lowered from the through hole (322) by user operation while in a raised state, causing the winding rolls (320) to move by their own weight.

[0050] And the actuator (330) can be driven by user operation or by remote control.

[0051] Accordingly, the mobile vehicle fire suppression device according to the embodiment of the present invention can be operated by pressing the switch of the device after positioning the device at the fire vehicle (site), so that the suffocating fire extinguishing cloth fixed to the top of the device is rapidly deployed, thereby enabling safe and immediate fire suppression as well as preventing the spread of flames and harmful gases, thereby reducing secondary damage.

[0052] Due to the device's wide versatility, it can be applied not only to new buildings where the structure and facilities can be modified during construction, but also to existing buildings or small buildings where it is difficult to change the structure and systems.

[0053] It can effectively respond to vehicle fires because the operation method is simple enough for an ordinary person without protective equipment to extinguish the fire alone.

[0054] The present invention has been described with reference to embodiments illustrated in the drawings, but this is merely illustrative, and those skilled in the art will understand that various modifications and equivalent alternative embodiments are possible therefrom. Accordingly, the true technical scope of protection of the present invention should be determined by the technical spirit of the appended claims. Explanation of the symbols
