Description

Technical Field

[0001] The utility model relates to the field of fire-fighting equipment for automobile parking spaces, and in particular to an intelligent fire-extinguishing device for automobile parking spaces. Background Art

[0002] The power battery of electric vehicles is a high-energy-density lithium-ion battery. Almost all electric vehicle fire incidents are related to the power battery. Once a thermal runaway fire occurs in an electric vehicle in a parking space, the combustion reaction of its lithium-ion battery pack is violent, and it is almost impossible to extinguish it with existing conventional fire-fighting measures. Moreover, the high-temperature jet flames generated laterally will ignite adjacent vehicles within a few minutes, and adjacent vehicles will also produce a chain reaction of thermal runaway reactions. If control measures are not taken, the fire will spread to the entire parking lot, causing huge property losses. Utility Model Content

The bottom of the fireproof cover 1 is provided with an opening. The fireproof cover 1 is fixedly installed above the parking space through the bracket 2. The shape of the fireproof cover 1 can be freely selected according to the shape of the parking space, preferably a square. The shape of the bracket 2 matches the shape of the fireproof cover 1. The material of the fireproof cover 1 can be glass fiber silicone coated cloth. The fire sprinkler 3, the temperature sensor 4 and the smoke sensor 5 are all installed in the fireproof cover 1, wherein two temperature sensors 4 and two smoke sensors 5 can be provided, and two temperature sensors 4 or two smoke sensors 5 are arranged at intervals at the front and rear ends of the fireproof cover 1. The fire sprinkler 3 is connected to the external fire hydrant through a water pipe, and also includes a lifting component 6. The lower end of the fireproof cover 1 is sleeved with a first fixing frame 7, which is connected to the lifting component 6 and moves up and down under the action of the lifting component 6. The fire sprinkler 3 can be provided in plurality and can be installed on the top of the fireproof cover 1 and on the first fixing frames 7 located at the bottom of the left and right sides. For the convenience of fire prevention The fire hood 1 is retracted, and the fire sprinkler 3 located on the first fixing frame 7 can be connected to the water pipe through a hose. When in use, the open fire above the car can be extinguished through the top fire sprinkler 3, and the open fire on the battery can be directly extinguished through the fire sprinkler 3 on both sides. When the first fixing frame 7 contacts or approaches the bracket 2, the fire hood 1 is completely folded on the bracket 2. When the first fixing frame 7 contacts the parking space, the fire hood 1 is unfolded and forms a closed space between the parking space. In order to improve the high temperature resistance, a hard fireproof board can be added to the top of the space, that is, the inner top of the fire hood 1. The up and down movement of the fire hood 1 can be electrically controlled or manually controlled by the lifting component 6. In addition, a manual switch can be set to control the operation of the lifting component 6. When no fire occurs, the fire hood 1 is put down and used as a dust cover or protective cover. In order to improve the supporting strength of the fire hood 1 and facilitate the fixation of the fire hood 1 and the bracket 2, a second fixing frame 8 can be set on the upper end of the fire hood 1, wherein the first fixing frame 7 and the second fixing frame 8 can be the same or different, and both are made of high temperature resistant metal materials.

[0035] In this embodiment, by setting the fireproof cover 1, the lifting component 6, the temperature sensor 4, the smoke sensor 5, and the first fixed frame 7, when a fire occurs, the fireproof cover 1 can be used to isolate the burning vehicle from the surrounding vehicles or equipment to prevent the fire from spreading. Combined with the setting of the fire sprinkler 3, the open flame can be extinguished. At the same time, a water pool is formed in the fireproof cover 1 to immerse the battery, cool the battery, and isolate oxygen to achieve the ultimate purpose of extinguishing the fire. The specific process is that when the smoke sensor 5 and the temperature sensor 4 detect a fire, the lifting component 6 controls the first fixed frame 7 to descend, and the bottom of the fireproof cover 1 is driven by the first fixed frame 7 until it contacts the parking space to form an enclosed space. At this time, the fireproof cover 1 completely wraps the burning vehicle, and the fire sprinkler 3 is opened to cool the inside of the fireproof cover 1 and extinguish the open flame, and accumulate water to form a water pool that immerses the burning battery.

[0036] In the present invention, preferably, Figure 1 , Figure 2 As shown, a sandbag circle 9 is further provided at the lower end of the fireproof cover 1. The sandbag circle 9 can be independently provided with the fireproof cover 1 or can be integrally formed. The sandbag circle 9 is provided around the entire opening. The sandbag circle 9 is filled with sand. The sandbag circle 9 is located on the side of the first fixed frame 7 close to the parking space, and the top of the sandbag circle 9 is lower than the top of the first fixed frame 7.

[0037] In the present embodiment, by setting up a whole circle of sandbag enclosure 9, the spread of fire can be further prevented, and the loss of water in the pool can be reduced. In addition, the weight can be increased to effectively prevent the fireproof cover 1 from being washed away by the water flow; by setting the sandbag enclosure 9 on the side of the first fixed frame 7 close to the parking space, the bottom of the sandbag enclosure 9 is lower than the bottom of the first fixed frame 7, the blocking of the first fixed frame 7 and the gravity of the water itself can be utilized to further prevent the fireproof cover 1 from being washed away by the water flow. Specifically, at the beginning, the impact force of water on the sandbag enclosure 9 will be blocked by the first fixed frame 7. As the amount of water increases, when the water level is higher than the sandbag enclosure 9, the water above the sandbag enclosure 9 will provide a downward force on the sandbag enclosure 9, and this force will increase as the amount of water increases.

[0038] In the present invention, preferably, Figure 1 , Figure 2 and Figure 3 As shown, the fireproof cover 1 is also provided with an auxiliary support frame 10, which is sleeved on the outside of the fireproof cover 1 and is located between the first fixing frame 7 and the second fixing frame 8. It is further preferred that the auxiliary support frame 10 includes two, and the two auxiliary support frames 10, the first fixing frame 7 and the second fixing frame 8 are arranged at equal intervals. The auxiliary support frame 10 is made of high temperature resistant metal or other materials, and its size is smaller than that of the first fixing frame 7 and the second fixing frame 8, ensuring that the fireproof cover 1 occupies less space after being folded.

[0039] In this embodiment, the auxiliary support frame 10 is provided to support the fireproof cover 1, thereby further improving the impact resistance of the fireproof cover 1 and effectively maintaining the shape of the fireproof cover 1.

[0040] In the present invention, preferably, Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the lifting assembly 6 includes a winding wheel 61, a connecting frame 62 and four steel wire ropes 63. The connecting frame 62 is fixedly installed on one end of the bracket 2 located at the rear of the vehicle. The winding wheel 61 is rotatably installed on the connecting frame 62 and driven by a motor 64. When the motor 64 is damaged or powered off, it can also be manually controlled. One end of the four steel wire ropes 63 is respectively connected to the four corners of the first fixed frame 7, and the other end passes through the bracket 2 and is wound and connected with the winding wheel 61; the second fixed frame 8 and the auxiliary support frame 10 are both provided with a guide ring 11, and the three guide rings 11 at the same corner are coaxially arranged, and the steel wire rope 63 passes through three guide rings 11 and is connected to the first fixed frame 7; the bracket 2 is provided with a guide wheel 12, and the steel wire rope 63 is wound and connected with the winding wheel 61 through the guide wheel 12.

[0041] In this embodiment, by setting up the winding wheel 61, the connecting frame 62 and the four steel ropes 63, the motor 64 can be used to drive the winding wheel 61 to drive the steel ropes 63 to realize the synchronous upward and downward extension of the fireproof cover 1; combined with the setting of the guide ring 11, the steel ropes 63 can be prevented from being offset, ensuring that the bottom of the fireproof cover 1 is always in a horizontal state; combined with the setting of the guide wheel 12, the friction resistance between the steel ropes 63 and the bracket 2 can be reduced, so that the fireproof cover 1 can move more smoothly.

[0042] In the present invention, preferably, Figure 1 , Figure 2 As shown, a vent hole is provided at the top of the fireproof cover 1, and a one-way valve 13 is installed in the vent hole. The opening direction of the one-way valve 13 is from the inside of the fireproof cover 1 to the outside of the fireproof cover 1.

[0043] In this embodiment, the vent hole is provided to facilitate the discharge of gas inside the fireproof cover 1 and achieve an automatic pressure relief effect. Combined with the provision of the one-way valve 13, it is possible to prevent external oxygen from entering the fireproof cover 1 while ensuring the discharge of gas.

[0044] In the present invention, preferably, Figure 2As shown, a water level switch (not shown in the figure) is installed at one end of the fireproof cover 1 near the bottom, and the water level switch (not shown in the figure) is connected to the fire sprinkler 3. When the water level switch (not shown in the figure) is immersed, the fire sprinkler 3 is closed. In the event of a fire, when the water level is lower than the water level switch (not shown in the figure), the fire sprinkler 3 will be reopened until the immersion is stopped.

[0045] In this embodiment, by setting a water level switch (not shown in the figure), the opening and closing of the fire sprinkler 3 can be automatically controlled to ensure that the battery is completely immersed while preventing the car from becoming a water-soaked car. In addition, it can also reduce the pressure of water on the fireproof cover 1 to prevent the fireproof cover 1 from being expanded by water.

[0046] In the present invention, preferably, Figure 1 , Figure 3 As shown, a fire extinguishing bomb 14 is also installed in the fireproof cover 1. Two fire extinguishing bombs 14 can be provided. The two fire extinguishing bombs 14 are respectively located at the front and rear ends of the fireproof cover 1. The bursting temperature of the fire extinguishing bomb 14 is not lower than the sensing temperature of the temperature sensor 4.

[0047] In this embodiment, by setting the fire extinguishing bomb 14, dry powder or other substances can be provided to suppress the fire when the temperature reaches the bursting temperature of the fire extinguishing bomb 14. Specifically, when the temperature is lower than the bursting temperature, only the fire sprinkler 3 is used to cool down and extinguish the fire. When the fire sprinkler 3 cannot effectively suppress the fire, the temperature in the fireproof cover 1 will continue to rise. When the bursting temperature of the fire extinguishing bomb 14 is reached, the fire extinguishing bomb 14 will burst.

[0048] Working principle:

[0049] like Figures 1 to 4As shown, when the smoke sensor 5 detects a smoke signal, the external controller connected to the smoke sensor 5 will first control the charging pile to cut off the power, and then control the motor 64 to drive the first fixing frame 7 to move down a certain distance, preferably half the height, in order to avoid the occurrence of inaccurate detection effect of the temperature sensor 4 due to temperature diffusion. On the other hand, an alarm message will be sent to the property and the car owner. When the temperature reaches the sensing temperature of the temperature sensor 4, the controller will control the first fixing frame 7 to continue to move down until the sandbag circle 9 at the lower end of the fireproof cover 1 contacts the ground, and on the other hand, it will control The fire sprinkler 3 sprays water. As water is continuously injected, water accumulates in the enclosed space formed between the fireproof cover 1 and the parking space to form a pool until the water surface of the pool completely submerges the burning battery. At this time, the water level switch (not shown in the figure) located on the fireproof cover 1 will control the fire sprinkler 3 to stop spraying water through the controller. During this process, when the water level decreases, the controller will control the fire sprinkler 3 to spray water again. When the fire is not controlled, the temperature in the fireproof cover 1 will continue to rise until it reaches the bursting temperature of the fire extinguishing bomb 14. At this time, the fire extinguishing bomb 14 bursts and sprays dry powder or other substances, achieving the effect of further cooling and extinguishing the fire.
