Fire suppression system

Abstract

A fire extinguishing system for vehicles includes a two-section support mechanism and a fire-resistant mechanism. Each support mechanism includes a support unit located on the vehicle and a release unit rotatably connected to the support unit. The fire-resistant mechanism includes a roller removably placed on the release unit and a fire blanket wound around the roller. The release unit can switch between a supported state and a released state. In the supported state, the fire-resistant mechanism is located on the release unit; in the released state, the release unit tilts downwards, causing the fire-resistant mechanism to fall, and the fire blanket covers the vehicle. Utilizing the design of the support and fire-resistant mechanisms, the fire-resistant mechanism does not require additional electricity or a power source; it can automatically deploy under its own weight to cover the vehicle during the downward descent, making fire extinguishing relatively easy and effective.

Description

Technical Field

[0001] The present invention relates to a fire fighting equipment, in particular to a fire extinguishing system. Prior Art

[0002] When a traditional vehicle catches fire, it is usually put out using a portable fire extinguisher or a sprinkler system. With the development of trams, it is relatively difficult to put out a fire using traditional methods. Therefore, the current method is mainly to cover the vehicle with a fire blanket to put out the fire. However, if the vehicle fire is relatively large or fully burned, it is difficult for personnel to approach, making it relatively difficult for personnel to cover the fire blanket, causing the fire to spread quickly. Summary of the invention

[0003] Therefore, one of the objects of the present invention is to provide a fire extinguishing system that can overcome at least one disadvantage of the prior art.

[0004] Therefore, the fire extinguishing system of the present invention is applicable to a vehicle and includes two supporting mechanisms and a fire protection mechanism.

[0005] The supporting mechanisms are spaced apart from each other in a first direction. Each supporting mechanism comprises a supporting unit spaced apart above the vehicle and a releasing unit rotatably connected to the supporting unit.

[0006] The fire protection mechanism comprises two rollers which are respectively and detachably placed on the release units of the supporting mechanisms, and a fire extinguishing blanket which is wound around the rollers and located between the supporting mechanisms.

[0007] The release units of the supporting mechanisms can be switched between a supporting state and a releasing state relative to the supporting units. In the supporting state, the releasing units restrict the fire protection mechanism to the releasing units. In the releasing state, the releasing units are tilted downward relative to the supporting units, so that the fire protection mechanism falls downward from the releasing units, and the fire blanket is unfolded to cover the vehicle.

[0008] Therefore, another object of the present invention is to provide a fire extinguishing system that can overcome at least one disadvantage of the prior art.

[0009] The fire extinguishing system is suitable for a vehicle and comprises a supporting mechanism and a fire protection mechanism.

[0010] The supporting mechanism comprises a supporting unit which is spaced apart and located above the vehicle, and a releasing unit. The releasing unit and the supporting unit jointly define a setting space, and an opening which can be closed and connected to the setting space.

[0011] The fire protection mechanism comprises a fire blanket which is detachably placed in the setting space. The fire blanket extends along a first direction and comprises a central portion and two winding portions which extend in opposite directions from the central portion in a second direction intersecting the first direction.

[0012] The release unit can be switched between a supporting state and a releasing state relative to the supporting unit. In the supporting state, the release unit limits the fire protection mechanism in the setting space. In the releasing state, the release unit opens the opening so that the fire protection mechanism falls down from the opening, and the fire blanket unfolds and covers the vehicle.

[0013] The effect of the present invention is that: by utilizing the design of the supporting mechanism and the fire protection mechanism, the fire protection mechanism can fall by utilizing its own gravity, and the fire blanket automatically unfolds during the falling process. Compared with the prior art, the fire extinguishing difficulty is low, and the fire of the vehicle can be effectively extinguished. Simple diagram description

Implementation

[0015] Before the present invention is described in detail, it should be noted that similar elements are represented by the same reference numerals in the following description.

[0016] Referring to FIG. 1 and FIG. 2 , a first embodiment of the fire extinguishing system of the present invention is applicable to a fixed surface 90 and a vehicle 91. The fixed surface 90 may be, but not limited to, a ceiling surface, a wall surface, or a surface of a ceiling set up outdoors. The vehicle 91 may be, but not limited to, an electric vehicle, such as a household electric RV or electric RV, or a large vehicle such as an electric bus. The fire extinguishing system includes two support mechanisms 1 that can be set on the fixed surface 90, a fire prevention mechanism 2 that can be detachably placed on the support mechanism 1, a sensing module 3, and a control module 4 that is signal-connected to the sensing module 3 and the support mechanism 1.

[0017] The supporting mechanisms 1 are spaced apart from each other in a first direction X1. Each supporting mechanism 1 includes a supporting unit 11 that can be connected to the fixing surface 90 and is spaced apart above the vehicle 91, a releasing unit 12 rotatably connected to the supporting unit 11, and two limiting units 13 connected to the supporting unit 11 and the releasing unit 12.

[0018] In each of the supporting mechanisms 1, the supporting unit 11 includes a fixed bracket 111 fixedly connected to the fixed surface 90, and two tilting stoppers 112 respectively connected to the fixed bracket 111. The fixed bracket 111 includes an extension section 113 in a rod shape extending downward from the fixed surface 90, and a fixed section 114 in a rod shape extending laterally from the bottom side of the extension section 113 in a second direction X2. The fixed section 114 includes two fixed ends 115 spaced apart from each other in the second direction X2. The second direction X2 is transverse to the first direction X1. The tilting stoppers 112 are respectively arranged at the bottom side of the fixed ends 115. The side surface of each tilting stopper 112 is roughly triangular. The release unit 12 includes two guide brackets 121 in a rod shape and connected to the fixed ends 115 in a downward swingable manner. Each guide bracket 121 extends laterally from the corresponding fixed end 115 in the opposite direction to the other guide bracket 121. In this embodiment, the guide bracket 121 on the left extends leftward from the fixed end 115 on the left, and the guide bracket 121 on the right extends rightward from the fixed end 115 on the right.

[0019] In each of the support mechanisms 1, each of the position limiting units 13 includes a connection bracket 131 that can be fixedly connected to the fixed surface 90, a first connection member 132 connected to the bottom end of the connection bracket 131, and a second connection member 133 connected to the side of the respective guide bracket 121 opposite to the corresponding fixed end 115 (in FIG. 1, only the first connection member 132 and the second connection member 133 of the support mechanism 1 located at the front side are shown). Each of the guide brackets 121 is located between the corresponding connection bracket 131 and the corresponding fixed bracket 111 in the second direction X2. The first connection member 132 and the second connection member 133 are detachably connected to each other. One of the first connection member 132 and the second connection member 133 of each of the position limiting units 13 is an electromagnet whose signal is connected to the control module 4, and the other is a magnetic member. Thereby, when the electromagnet is powered on, it can be magnetically attracted to the magnetic part, and when the electromagnet is powered off, it can be separated from the magnetic part because no magnetic force is formed.

[0020] Referring to FIGS. 2 to 4 , the release unit 12 of the support mechanism 1 can rotate between a support state and a release state relative to the support unit 11. When the release unit 12 is in the support state, the first connection member 132 and the second connection member 133 are connected to each other by magnetic force, so that the guide bracket 121 maintains a lateral extension, and the gap between the guide bracket 121 and the corresponding connection bracket 131 is relatively small, or close without a gap. When the release unit 12 is in the release state, the first connection member 132 and the second connection member 133 are controlled to be powered off and have no magnetic force and are separated from each other, so that the guide bracket 121 swings downward relative to the fixed bracket 111 until it is respectively placed against the tilt limit member 112 and is limited to a predetermined slope. In this way, the release unit 12 tilts downward relative to the support unit 11, and the gap between the guide bracket 121 and the corresponding connection bracket 131 is larger than the gap in the support state.

[0021] In this embodiment, the fire extinguishing system may further include an auxiliary connecting mechanism 5 connecting the supporting mechanisms 1, and the auxiliary connecting mechanism 5 includes a plurality of auxiliary brackets 51 of equal length and in the shape of long straight strips. Several of the auxiliary brackets 51 are respectively connected to the top side of the connecting bracket 131, several are respectively connected to the bottom side of the connecting bracket 131, and the rest are connected to the top side of the extension section 113. In this way, the spacing between the components of the supporting mechanism 1 can be ensured to be fixed and consistent. In some embodiments, the auxiliary connecting mechanism 5 can be omitted.

[0022] Referring to FIG. 1 and FIG. 2 , the fire prevention mechanism 2 includes two rollers 21 detachably placed on the release units 12 of the support mechanisms 1, and a fire blanket 22 wound around the rollers 21 and located between the support mechanisms 1. The rollers 21 are spaced left and right in the second direction X2, and each of the rollers 21 extends forward and backward along the first direction X1. The fire blanket 22 extends forward and backward and includes a central portion 221 and two winding portions 222 connected to the left and right sides of the central portion 221, respectively. The winding portions 222 extend from the central portion 221 and roll upward and inwardly on their respective rollers 21, so that the winding portions 222 can be detachably wound around the corresponding rollers 21, respectively. Specifically, each of the winding portions 222 is formed by winding the originally flattened portion toward the central portion 221.

[0023] The fire blanket 22 is used to help quickly extinguish the fire when covering or covering the burning objects. The fire blanket 22 includes, for example but not limited to, a porous material and a fire extinguishing component filled in the holes of the porous material. The porous material can be, but not limited to, a porous non-woven fabric, a porous woven fabric, a porous foam or a porous polymer film material. The fire extinguishing component includes, for example but not limited to, a fire extinguishing material that generates a flame retardant when heated, and an adhesive for attaching the fire extinguishing material to the porous material. The fire extinguishing material includes, for example but not limited to, alkali metal carbonates, alkali metal bicarbonates, halides, ammonium phosphates, potassium salts, or alkali metal chlorides. The fire blanket 22 may also include a heat-resistant non-combustible layer (not shown) formed on a surface of the porous material facing the vehicle 91, such as, but not limited to, a poly(m-phenylene)diamine fiber layer, a glass fiber layer, a ceramic layer, or a glass fiber ceramic layer.

[0024] The sensing module 3 can be a temperature sensor or a smoke sensor, and is disposed on the bottom side of one of the fixing brackets 111. When the sensing module 3 is the temperature sensor, it can generate a warning signal when it detects that the ambient temperature is higher than a predetermined temperature. When the sensing module 3 is the smoke sensor, it can generate the warning signal when it detects that the smoke in the environment is higher than a predetermined concentration. In this way, the sensing module 3 can sense the high temperature or thick smoke when the vehicle 91 is on fire, and transmit the warning signal to the control module 4.

[0025] In some embodiments, the sensing module 3 can be disposed on the ceiling surface, the wall, or the ceiling, as long as it can generate the warning signal when sensing the high temperature and / or smoke from the vehicle 91 when it is on fire.

[0026] The control module 4 is disposed on the wall and can execute instructions and process data. The control module 4 can be a central processing unit, an embedded processor, or a microprocessor. The control module 4 can be activated when triggered by the warning signal to control the limit unit 13 to be powered off, so that the first connecting member 132 and the second connecting member 133 are converted from being connected to each other to being disconnected from each other. In this way, the release unit 12 can be converted from the supporting state to the releasing state.

[0027] In some embodiments, the control unit may also be disposed on a ceiling or a ceiling. In this embodiment, the parking direction of the vehicle 91 is the same as the second direction X2. In some embodiments, the parking direction of the vehicle 91 may be different from the second direction X2.

[0028] 2 to 4 , when the fire extinguishing system is used, the release unit 12 is first placed in the supporting state, and the roller 21 of the fire protection mechanism 2 is placed on the release unit 12 , so that the fire blanket 22 is located above the vehicle 91 .

[0029] When the sensing module 3 senses that the vehicle 91 is on fire and sends the trigger signal to the control module 4, the control module 4 is triggered to control the limiting unit 13 to be powered off, so that there is no magnetic force between the first connecting member 132 and the second connecting member 133 and they are not connected to each other; in each of the supporting structures, the guide bracket 121 swings downward and is limited by the tilting limiting member 112, and extends and tilts to the left and downward, and to the right and downward respectively. At this time, the release unit 12 is converted from the supporting state to the releasing state. In this way, the roller 21 can roll down along the top surface of the downwardly tilted guide bracket 121 until it is separated from the supporting mechanism 1, and then continue to fall to the ground. In the process of the roller 21 rolling down and falling, the winding part 222 of the fire blanket 22 is driven to gradually unfold until the roller 21 and the fire blanket 22 are separated from each other, and the fire blanket 22 can be unfolded and covered on the vehicle 91 to extinguish the fire of the vehicle 91.

[0030] In more detail, when the release unit 12 is in the supporting state, the width of the roller 21 is greater than the corresponding gap, and the roller 21 is limited, so that the roller 21 swings against the guide bracket 121. When the release unit 12 is in the releasing state, the gap between each guide bracket 121 and the corresponding connecting bracket 131 can allow the roller 21 to roll down and move away from the guide bracket 121. Therefore, the corresponding roller 21 can roll down along the guide bracket 121, so that the fire blanket 22 can be unfolded and cover the vehicle 91.

[0031] Since the control module 4 only needs to control the limit unit 13 when the sensing module 3 detects that the vehicle 91 is on fire, so that the release unit 12 can be switched to the release state. After that, the fire protection mechanism 2 is actuated by rolling down along the guide bracket 121 by gravity, and continuing to fall down after leaving the guide bracket 121, thereby flattening the fire blanket 22, and no additional power or control system is required to control the deployment of the fire blanket 22. Therefore, during the deployment process, the winding portion 222 of the fire blanket 22 can avoid the situation where the power or control system is affected by high temperature or fire and fails, causing the fire blanket 22 to be unable to be deployed, thereby ensuring that the fire blanket 22 extinguishes the fire of the vehicle 91.

[0032] In addition, since the fire blanket 22 is detachably wound on the roller 21, the fire blanket 22 or the used fire blanket 22 can be replaced at any time. Thus, the support mechanism 1 and the roller 21 can be reused.

[0033] In some embodiments, the magnetic part and the electromagnet of the limiting unit 13 may be replaced by an electric lock including a motor connected to the control module 4 by a signal and a limiting part moved by the motor.

[0034] In some embodiments, a mechanical lock, such as a latch lock, can be used to replace the magnetic member and the electromagnet, and a signal can be used to connect the alarm of the control module 4. When the control module 4 receives the warning signal, the alarm is controlled to emit a warning sound or a warning light indicating a fire alarm, prompting the personnel who receive the alarm to go to the scene and manually open the mechanical lock, which can also switch the release unit 12 to the release state.

[0035] Referring to Figures 5 to 7, a second embodiment of the fire extinguishing system of the present invention is shown. The second embodiment is similar to the first embodiment, and the difference lies in: the support mechanism 1, the fire protection mechanism 2, and the control module 4. The differences are described in detail below.

[0036] The number of the support mechanism 1 is one, which is located above the vehicle 91 at intervals, and includes the support unit 11 fixedly connected to the fixed surface 90, the release unit 12 rotatably connected to the support unit 11, and the limit unit 13 connected to the support unit 11 and the release unit 12 and signal-connected to the control module 4.

[0037] The support unit 11 includes two fixed brackets 111 that are respectively in the shape of a square frame and extend forward and backward. The fixed brackets 111 can be respectively arranged on the fixed surface 90 and are spaced from each other left and right in the second direction X2. The release unit 12 includes two cover plates 122 that are respectively in the shape of a long plate and extend forward and backward. The cover plates 122 are respectively rotatably connected to the bottom sides of their respective fixed brackets 111. The fixed brackets 111 of the support unit 11 and the cover plates 122 of the release unit 12 jointly define a setting space 141 for placing the fire prevention mechanism 2, and an opening 142 that is connected to the setting space 141 and faces downward (as shown in FIG. 7). The cover plate 122 can openably close the opening 142.

[0038] The position limiting unit 13 includes the first connecting member 132 and the second connecting member 133 respectively connected to the bottom side of the cover plate 122. The first connecting member 132 and the second connecting member 133 are detachably connected to each other. One of the first connecting member 132 and the second connecting member 133 is a magnetic member, and the other is an electromagnet that is signal-connected to the control module 4 and can be magnetically attracted to the magnetic member when powered on. In this way, when the position limiting unit 13 is powered on, the first connecting member 132 and the second connecting member 133 generate magnetic force and are connected to each other. When the position limiting unit 13 is powered off, the magnetic force between the first connecting member 132 and the second connecting member 133 disappears and they are not connected to each other.

[0039] The release unit 12 can switch between the support state and the release state relative to the support unit 11. In the support state, the first connection member 132 and the second connection member 133 are connected to each other by magnetic force, so that the cover plate 122 is parallel to each other and closes the opening 142. When there is no magnetic force between the first connection member 132 and the second connection member 133 and they are not connected to each other, the cover plate 122 swings down to open the opening 142, and the release unit 12 switches from the support state to the release state. In this embodiment, the auxiliary connection mechanism 5 (as shown in FIG. 1) can be omitted.

[0040] The fire protection mechanism 2 includes the fire blanket 22 movably placed in the installation space 141. The fire blanket 22 extends forward and backward along the first direction X1, and includes a central portion 221 and two winding portions 222 extending from the central portion 221 to the left and right in the second direction X2. The structure and material of the fire blanket 22 are similar to those of the first embodiment, so they will not be described in detail here.

[0041] The sensing module 3 may be the temperature sensor or the smoke sensor, and is similar to the first embodiment, and will not be described in detail here. In this example, the sensing module 3 is disposed on the bottom side of one of the cover plates 122. In some embodiments, the sensing module 3 may also be disposed on the bottom side of the fixing bracket 111, the ceiling, the wall or the ceiling, as long as it can sense high temperature or smoke when the vehicle 91 is on fire.

[0042] When the fire extinguishing system is used, the release unit 12 is first placed in the supporting state to close the opening 142 , and the fire protection mechanism 2 is located in the setting space 141 and placed on the release unit 12 , so that the fire blanket 22 is located above the vehicle 91 .

[0043] When the sensing module 3 senses that the vehicle 91 is on fire and sends the trigger signal to the control module 4, the control module 4 is triggered to control the limiting unit 13 to be powered off, so that the first connecting member 132 and the second connecting member 133 have no magnetic force and are not connected to each other; the cover plate 122 of the release unit 12 swings down to open the opening 142, so that the release unit 12 is switched to the release state. In this way, the fire blanket 22 is no longer limited to the setting space 141 and falls down from the opening 142.

[0044] In some embodiments, the cover plate 122 may also be hollow, as long as the opening 142 can limit the fire protection mechanism 2 to the setting space 141.

[0045] Since the control module 4 only needs to control the limit unit 13 when the sensing module 3 detects that the vehicle 91 is on fire, the release unit 12 can be switched to the release state. After that, the fire prevention mechanism 2 is actuated by falling down from the opening 142 due to gravity, and no additional power or control system is required to control it.

[0046] Referring to FIG8 and FIG9 , a third embodiment of the fire extinguishing system of the present invention is shown. The third embodiment is similar to the second embodiment, except that the fire protection mechanism 2 of the third embodiment further includes the roller 21. The number of the rollers 21 is two.

[0047] Each of the rollers 21 extends forward and backward along the first direction X1. The winding portions 222 of the fire blanket 22 extend from the central portion 221 and roll upward and inward on the respective rollers 21, so that the winding portions 222 can be removably wound on the corresponding rollers 21. When the release unit 12 is in the release state, the fire blanket 22 falls, the winding portion 222 unfolds, the rollers 21 are separated from the fire blanket 22, and the fire blanket 22 covers the vehicle 91 to extinguish the fire of the vehicle 91.

[0048] In some embodiments, when the length of the roller 21 is not greater than the length of the winding portion 222 , the roller 21 may not be separated from the winding portion 222 and may still be unfolded and cover the vehicle 91 .

[0049] In summary, the fire extinguishing system of the present invention utilizes the design of the support machine and the fire prevention mechanism 2, and the release unit 12 can switch between the support state and the release state relative to the support unit 11, so that the fire prevention mechanism 2 can fall by its own gravity, and the fire blanket 22 automatically unfolds during the falling process, without the need for additional electricity or power source. In addition, utilizing the design of the sensing module 3 and the control module 4, the fire prevention mechanism 2 can automatically fall when the vehicle 91 is on fire. Furthermore, utilizing the design of the guide bracket 121, the roller 21 can be guided to move downward along the guide bracket 121, so the purpose of the present invention can be achieved.

[0050] However, what is described above is only an embodiment of the present invention and should not be used to limit the scope of implementation of the present invention. All simple equivalent changes and modifications made according to the scope of the patent application of the present invention and the content of the patent specification are still within the scope covered by the patent of the present invention.
