Description

Technical Field

[0001] The invention relates to a sealing structure of a fire extinguisher box. Background Art

[0002] With the development and progress of society, electric vehicles and other transportation tools are becoming more and more popular. Among them, the number of electric vehicles and other transportation tools driven by electric energy is increasing year by year due to the requirements of environmental protection.

[0003] However, electric vehicles and other vehicles are usually powered by lithium batteries, which have a high energy density. When the lithium batteries of electric vehicles and other vehicles explode, the electric vehicles and other vehicles are difficult to tow after the explosion. Most battery packs of electric vehicles and other vehicles are placed at the bottom of the electric vehicles and are sealed. It is difficult to extinguish the fire using conventional fire extinguishing methods, such as using a fire extinguisher or spraying water.

[0004] In addition, when electric vehicles and other vehicles are charging or parking, the charging current of the lithium battery is large and the temperature is also high, resulting in a higher probability of spontaneous combustion of electric vehicles and other vehicles when they are parked for charging.

[0005] In traditional multi-story parking garages, there is no isolation between parking spaces, and the spacing between electric vehicles and other vehicles is small. When electric vehicles and other vehicles burn (for example, due to spontaneous combustion due to battery short circuit, etc.), it is likely to affect surrounding electric vehicles and other vehicles, causing them to ignite each other.

[0006] In addition, traditional multi-story parking garages do not have fire extinguishing boxes and are unable to immerse and extinguish burning vehicles such as electric vehicles. Summary of the invention

[0007] The purpose of the present invention is to provide a fire extinguisher box sealing structure, in which the second side wall exists only on one side of the movable vehicle loading plate, which is less likely to interfere with the vehicle and facilitates moving the vehicle onto the movable vehicle loading plate.

[0008] The detailed technical solution adopted by the present invention is: a fire extinguisher box sealing structure, including a large frame with a parking space, a fire extinguisher box is arranged on the parking space, the fire extinguisher box includes a box body with an open top surrounded by side walls and a movable loading plate, and is characterized in that, in the enclosed state, the abutting edges of the movable loading plate abut against at least one abutting edge of the side wall, and a contact surface is formed at the abutment, and the angle between the contact surface and the translation direction of the movable loading plate is the abutting inclination angle, and the abutting inclination angle is greater than zero degrees and less than ninety degrees.

[0009] According to a further technical solution, the offset inclination angle is greater than one degree and less than ten degrees.

[0010] A further technical solution is that in the natural state, the angle between the abutting edges of the loading plate and the translational direction of the moving loading plate is a first sealing angle α, and the angle between the abutting edges of the side walls and the translational direction of the moving loading plate is a loading plate sealing angle β, and the first sealing angle α and the loading plate sealing angle β are both greater than zero degrees and less than ninety degrees.

[0011] According to a further technical solution, the first sealing angle α is less than or equal to the vehicle carrier plate sealing angle β, and the offsetting inclination angle is greater than or equal to the first sealing angle α and less than or equal to the vehicle carrier plate sealing angle β.

[0012] After the first side wall, the second side wall and the movable vehicle loading plate are enclosed, the supporting force between the movable vehicle loading plate and the first side wall gradually increases along the side of the movable vehicle loading plate, thereby ensuring a sealing effect.

[0013] According to a further technical solution, the first sealing angle α and the vehicle carrier plate sealing angle β are both greater than one degree and less than ten degrees.

[0014] According to a further technical solution, the side wall comprises a first side wall and a second side wall, the second side wall is fixedly connected to the movable vehicle loading plate, and the first side wall is U-shaped when viewed from above.

[0015] According to a further technical solution, a sealing ear is fixedly provided on the first side wall or the second side wall.

[0016] It can improve the leakage path and ensure the sealing of the fire extinguishing box.

[0017] According to a further technical solution, a guiding slope is arranged on the inner side of the sealing ear.

[0018] According to a further technical solution, a guiding slope is arranged on the inner side of the sealing ear.

[0019] According to a further technical solution, a flexible sealing strip is provided on the contact surface between the first side wall and the second side wall, and / or the contact surface between the first side wall and the movable vehicle loading plate.

[0020] Can ensure the sealing of the fire extinguisher box.

[0021] According to a further technical solution, the sealing strip is fixedly connected to one or more of the first side wall, the second side wall and the movable vehicle loading plate, and the sealing strip is provided with at least one sealing protrusion; the sealing protrusion is provided with an elastic hole; the cross-section of the sealing protrusion is semicircular, triangular, or trapezoidal.

[0022] When the first side wall is enclosed with the second side wall and the movable vehicle loading plate, no sealing strip needs to be placed, which is more convenient.

[0023] The holding pressure provided by the sealing protrusion can be increased, thereby ensuring the sealing performance of the fire extinguishing box.

[0024] The elasticity of the sealing protrusion can be ensured, thereby ensuring the sealing performance of the fire extinguishing box.

[0025] The above technical solution has the following advantages or beneficial effects:

[0026] 1) The second side wall is only present on one side of the mobile vehicle loading plate, which is less likely to interfere with the vehicle W and facilitates the movement of the vehicle W onto the mobile vehicle loading plate;

[0027] 2) After the first side wall, the second side wall and the movable vehicle loading plate are enclosed, the holding force between the movable vehicle loading plate and the first side wall gradually increases along the side of the movable vehicle loading plate, thereby ensuring a sealing effect;

[0028] 3) When the first side wall is enclosed by the second side wall and the movable vehicle loading plate, there is no need to place a sealing strip, which is more convenient. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0045] The technical solution of the present invention will be described below in conjunction with the accompanying drawings of the embodiments of the present invention.

[0046] First embodiment.

[0047] The three-dimensional car park with a fire extinguisher box of the first embodiment comprises a large frame 1 and a lifting device 2. The large frame 1 is provided with a lifting space 111 and at least two parking spaces 11. The lifting device 2 can move along the lifting space 111. The parking spaces 11 are respectively connected to the lifting space 111.

[0048] The frame 1 includes vertical beams 12 and horizontal beams 13 ; the vertical beams 12 and the horizontal beams 13 are fixedly connected to form the frame 1 in a frame shape.

[0049] The lifting device 2 is a conventional device that can achieve lifting and maintaining position; for example, the lifting device 2 includes a lifting frame 21 and a lifting drive device 221 fixed on the lifting frame 21 (the lifting drive device 221 is usually powered by an electric wire with a protective device, and the electric wire is not drawn). Both ends of the lifting frame 21 are hinged with lifting gears 23 driven by the lifting drive device 221. The large frame 1 includes a vertical beam 12, and the vertical beam 12 is fixedly provided with a lifting rack 231. The lifting gears 23 are respectively engaged with the lifting rack 231. Usually, the lifting drive device 221 is a reduction motor with a self-locking function, which drives the lifting gear 23 to rotate forward and reverse through the chain of the lifting device 2 (not drawn in the figure), thereby realizing the lifting and lowering of the lifting device 2. Of course, the lifting device 2 can also be lifted and lowered by other means, such as by traction with a lifting rope.

[0050] The large frame 1 and the lifting device 2 are both provided with a translation device 3 .

[0051] The three-dimensional parking garage with a fire extinguisher box of the first embodiment further comprises a fire extinguisher box 4 disposed in the parking space 11 and having a flame retardant property, and the fire extinguisher box 4 comprises a first side wall 41, a second side wall 42 and a movable vehicle loading plate 43. The fire extinguisher box 4 is made of conventional flame retardant materials, such as iron plates.

[0052] At least one side surface of the first side wall 41 is exposed to form a box side notch 411 , and the second side wall 42 completely covers the box side notch 411 , so that the first side wall 41 , the second side wall 42 and the movable vehicle loading plate 43 together form a space with an open top.

[0053] The translation device 3 is detachably connected to the fire box 4 and can drive the fire box 4 to translate. The translation device 3 is a device for driving the fire box 4 to translate; for example, the translation device 3 can be a cylinder, a hydraulic cylinder, etc. horizontally arranged on the large frame 1. The output end of the translation device 3 is detachably connected to the fire box 4 by conventional means such as inserting a T-shaped block into a T-shaped slot, and the translation device 3 and the fire box 4 can also be detachably connected by other means.

[0054] Working principle: the translation device 3 drives the fire extinguisher box 4 to translate onto the lifting device 2. After the lifting device 2 drives the fire extinguisher box 4 to move downward to the base device 19 (usually flush with the ground), the vehicle W can move to the mobile vehicle loading plate 43. After the lifting device 2 rises, the translation device 3 drives the fire extinguisher box 4 to enter the parking space 11 and reset.

[0055] If a vehicle W catches fire (for example, due to a short circuit in the battery), the parking spaces 11 are isolated by the flame-retardant fire extinguishing boxes 4 and cannot ignite each other, thereby preventing the vehicles W in the stereo garage from igniting each other and reducing losses.

[0056] Preferably, a long side surface of the first side wall 41 (i.e., the side surface corresponding to the length direction of the vehicle W) is exposed to form a box side notch 411, and the first side wall 41 is fixed in the parking space 11; the second side wall 42 is fixedly connected to the movable vehicle loading plate 43, and the translation device 3 can drive the second side wall 42 and the movable vehicle loading plate 43 to translate. The translation device 3 drives the second side wall 42 and the movable vehicle loading plate 43 to translate onto the lifting device 2, and the lifting device 2 drives the second side wall 42 and the movable vehicle loading plate 43 to move downward to the base device 19, and the vehicle W can move to the movable vehicle loading plate 43. After the lifting device 2 rises, the translation device 3 drives the second side wall 42 and the movable vehicle loading plate 43 to reset, so that the vehicle W passes through the box side notch 411 and enters the fire box 4. After the second side wall 42 and the movable vehicle loading plate 43 are lowered and moved onto the base device 19 , the second side wall 42 exists only on one side of the movable vehicle loading plate 43 , which is less likely to interfere with the vehicle W, making it easier to move the vehicle W onto the movable vehicle loading plate 43 .

[0057] Preferably, the translation device 3 includes a translation wheel 31 with rotational power, the translation wheel 31 is hinged on the bottom end surface of the parking space 11, and the mobile vehicle loading plate 43 abuts against the translation wheel 31, so that the translation device 3 and the fire box 4 are detachably connected. The translation wheel 31 rotates and relies on the friction between the translation wheel 31 and the mobile vehicle loading plate 43 to drive the second side wall 42 and the mobile vehicle loading plate 43 to translate. Compared with using a cylinder, this structure saves space.

[0058] Furthermore, the translation wheel 31 is provided with a translation guide groove 313, and the bottom end surface of the mobile vehicle carrier plate 43 is fixedly provided with a translation guide rail 32, and the translation guide rail 32 is embedded in the translation guide groove 313. Preferably, the cross section of the translation guide groove 313 is trapezoidal, and the upper bottom width of the cross section of the translation guide groove 313 is equal to the width of the translation guide rail 32. The fire extinguishing box 4 can be prevented from moving crookedly, thereby ensuring the sealing of the fire extinguishing box 4.

[0059] Preferably, the translation device 3 further includes a translation chain 312, and the translation wheels 31 arranged along the translation direction of the fire extinguisher box 4 form a row of translation wheels 31, and the translation wheels 31 in the same row are connected to each other through the translation chain 312. The translation wheels 31 in the same row can rotate synchronously to ensure that the fire extinguisher box 4 moves smoothly.

[0060] Preferably, the translation device 3 further includes a linkage rod 33 and a translation drive device 311 fixed on the large frame 1 or the lifting device 2, and the translation wheels 31 are in two or more rows; the translation wheels 31 in each row are respectively fixedly connected to the linkage rod 33, and the translation drive device 311 drives the linkage rod 33 to rotate. It can ensure that all the translation wheels 31 rotate synchronously and the fire box 4 moves smoothly.

[0061] Furthermore, it also includes a water inlet pipe 5 connected to a water source (not shown in the drawings), which extends into the parking space 11 and has an outlet located above the fire box 4. The water source is a device that continuously provides water, such as a pool or a tap water pipe supplied by a water pump.

[0062] If a vehicle W catches fire, it can prevent the vehicles W in the stereo garage from igniting each other, reduce losses, and at the same time, it can be immersed to cool down and increase the speed of fire extinguishing.

[0063] Furthermore, a horizontal spray head 51 is provided at the output end of the water inlet pipe 5; the spray head 51 array has a plurality of spray holes 511. Water is sprayed out from the spray holes 511 through the spray head 51, which can increase the spray area and improve the cooling and fire fighting effects.

[0064] Furthermore, it also includes a drainage pipe 6 connected to a drainage source (not shown in the drawings); a bottom drainage pipe 61 is provided at the other end of the drainage pipe 6; a long side surface of the first side wall 41 is exposed to form a box side notch 411, and the first side wall 41 is fixed in the parking space 11; the second side wall 42 is fixedly connected to the movable vehicle loading plate 43, and the translation device 3 can drive the second side wall 42 and the movable vehicle loading plate 43 to translate; the bottom drainage pipe 61 is connected to the bottom of the first side wall 41. When the vehicle W is completely extinguished after being immersed in water in the fire fighting box 4, the water is discharged through the bottom drainage pipe 61, which is convenient for subsequent treatment (such as transporting to the basic device 19 and then towing) of the vehicle W after the fire is extinguished; it can also circulate the water in the fire fighting box 4 to ensure the cooling effect on the burning vehicle W.

[0065] Furthermore, an upper limit drain pipe 62 is provided at the other end of the drain pipe 6; the upper limit drain pipe 62 is connected to the upper portion of the first side wall 41. When there is a lot of water in the fire extinguishing box 4, the excess water is discharged from the upper limit drain pipe 62, thereby preventing the water from overflowing from the top of the fire extinguishing box 4 to flow to other parking spaces 11 and affecting the vehicles W in other parking spaces 11.

[0066] Furthermore, it also includes an electric control device 9; the electric control device 9 includes a control device 91, and also includes a smoke and flame sensor device 92, a water inlet solenoid valve 95 and a water discharge solenoid valve 96 which are electrically connected to the control device 91 respectively; the smoke and flame sensor device 92 is arranged above the parking space 11 (usually arranged on the crossbeam 13), the water inlet solenoid valve 95 is arranged on the water inlet pipe 5, and the water discharge solenoid valve 96 is arranged on the bottom water discharge pipe 61. The control device 91 is usually an electric control device such as a PLC, and the smoke and flame sensor device 92 is a sensor for detecting flames, usually a conventional smoke sensor. When the vehicle W in the fire extinguishing box 4 burns and triggers the smoke and flame sensor device 92, the control device 91 controls the water inlet solenoid valve 95 to open and the water discharge solenoid valve 96 to disconnect, and water is supplied to the fire extinguishing box 4 to extinguish the fire; thereby fire automation can be realized.

[0067] Furthermore, it also includes a power connection device 8, a charging gun (not shown in the drawings) electrically connected to the first connector 81 is provided in the fire box 4, and the power connection device 8 includes a first connector 81 and a second connector 82, the first connector 81 is fixedly connected to the fire box 4, and the second connector 82 is fixed in the parking space 11, and the first connector 81 and the second connector 82 are abutted against each other to achieve a detachable electrical connection. It is convenient to charge the vehicle W in the fire box 4.

[0068] Preferably, in each parking space 11 , there are four outlets of the water inlet pipe 5 , four outlets of the bottom drainage pipe 61 , and four outlets of the upper limit drainage pipe 62 .

[0069] Further, a flexible sealing strip 49 is fixedly provided at the edge of the box side notch 411. The sealing strip 49 is usually made of rubber or the like, and can ensure the sealing of the fire fighting box 4 and prevent water leakage.

[0070] The fire extinguishing box for a stereoscopic car park of the first embodiment includes a fire extinguishing box 4 , which includes a first side wall 41 , a second side wall 42 and a movable vehicle loading plate 43 .

[0071] At least one side surface of the first side wall 41 is exposed to form a box side notch 411 , and the second side wall 42 completely covers the box side notch 411 , so that the first side wall 41 , the second side wall 42 and the movable vehicle loading plate 43 together form a space with an open top.

[0072] Preferably, a long side surface of the first side wall 41 is exposed to form a box side notch 411; and the second side wall 42 is fixedly connected to the movable vehicle loading plate 43, so as to facilitate moving the vehicle W onto the movable vehicle loading plate 43.

[0073] Furthermore, the second side wall 42 or the movable vehicle loading plate 43 is fixedly provided with a first connector 81, and a charging gun electrically connected to the first connector 81 is provided in the fire fighting box 4, so as to facilitate charging of the vehicle W in the fire fighting box 4.

[0074] Further, the bottom end surface of the mobile vehicle loading plate 43 is fixedly provided with a translation guide rail 32. The fire fighting box 4 can be prevented from moving crookedly, thereby ensuring the sealing of the fire fighting box 4.

[0075] Preferably, the edge of the mobile vehicle loading plate 43 opposite to the second side wall 42 is fixedly provided with a bottom plate protrusion 431. The sealing between the mobile vehicle loading plate 43 and the first side wall 41 can be ensured, and the position of the vehicle W on the mobile vehicle loading plate 43 can also be ensured.

[0076] Typically, the mobile vehicle loading plate 43 is fixedly provided with a wheel limiter 439; after the vehicle W moves onto the mobile vehicle loading plate 43, its wheels enter the grooves of the wheel limiter 439 (not shown in the drawings), which facilitates the positioning and secure placement of the vehicle W on the mobile vehicle loading plate 43.

[0077] The fire extinguisher box sealing structure includes a large frame 1 provided with a parking space 11, and a fire extinguisher box 4 is provided on the parking space 11. The fire extinguisher box 4 includes a box body with an open top surrounded by side walls and a movable vehicle loading plate 43. In the enclosed state, the abutting edges of the movable vehicle loading plate 43 abut against at least one abutting edge of the side wall, and a contact surface is formed at the abutment. The angle between the contact surface and the translation direction of the movable vehicle loading plate 43 is the abutting inclination angle, and the abutting inclination angle is greater than zero and less than ninety degrees.

[0078] Preferably, in the natural state, the angle between the abutting edges of the carrier plate 43 and the translational direction of the movable carrier plate 43 is a first sealing angle α, and the angle between the abutting edges of the side wall and the translational direction of the movable carrier plate 43 is a carrier plate sealing angle β. The first sealing angle α and the carrier plate sealing angle β are both greater than zero degrees and less than ninety degrees.

[0079] This facilitates the positioning of the movable vehicle loading plate 43 when it is inserted into the first side wall 41 , and can also ensure the supporting force between the movable vehicle loading plate 43 and the first side wall 41 , thereby ensuring the sealing effect.

[0080] Preferably, the first sealing angle α and the vehicle carrier plate sealing angle β are both greater than one degree and less than ten degrees.

[0081] Preferably, the first sealing angle α is less than or equal to the vehicle loading plate sealing angle β. After the first side wall 41, the second side wall 42 and the movable vehicle loading plate 43 are enclosed, the holding force between the movable vehicle loading plate 43 and the first side wall 41 gradually increases along the side of the movable vehicle loading plate 43, which can ensure the sealing effect.

[0085] Furthermore, a guiding slope 441 is provided on the inner side of the sealing ear 44. When the second side wall 42 and the first side wall 41 are enclosed, the guiding slope 441 can play a guiding role and ensure the positioning between the first side wall 41 and the second side wall 42.

[0086] Furthermore, the contact surface between the first side wall 41 and the second side wall 42, and / or the contact surface between the first side wall 41 and the movable vehicle loading plate 43 are provided with a flexible sealing strip 49.
