Description

Technical Field

[0001] The invention relates to a fire extinguishing device, in particular to a fire extinguishing device used in a parking space. Background Art

[0002] An electric vehicle is a vehicle that uses an onboard power supply as its motive force and a drive motor to drive its wheels. The onboard power supply is actually a rechargeable battery. The onboard battery charger can be used to replenish the battery after the battery is exhausted, just like refueling. The battery power can then be used to drive the vehicle. Although using batteries as vehicle power is more environmentally friendly, due to the limitations of current battery technology and some uncertain factors, electric vehicles are more prone to spontaneous combustion. Once spontaneous combustion occurs while the vehicle is parked, there is no one around, so the fire cannot be extinguished in the first place, resulting in the burning of the vehicle. In severe cases, an explosion may even occur, damaging not only the vehicle itself but also surrounding objects, seriously increasing accident losses. Summary of the invention

[0037] The lower water spray device includes a lower water pipeline 59 arranged in the sinking bin 2; the lower water pipeline 59 is provided with a plurality of lower water spray pipelines 60 connected to the lower water spray holes 5; the side water spray device includes a side water pipeline 61 arranged in the front and rear parts of the vertical frame 51; the upper end of the side water pipeline 61 is connected to one of the front and rear ends of the universal sprinkler 58; the water control device includes a water inlet pipeline 62 connected to the lower end of the side water pipeline 61; the water inlet pipeline 62 is connected to the lower water pipeline 59 through a hose 63; the water inlet pipeline 62 is provided with a first solenoid valve matching the smoke sensor 7.

[0038] The front and rear ends of the universal sprinkler 58 are not connected to the upper end of the side water pipe 61, and one end is connected to an auxiliary pipe 64; the lower end of the auxiliary pipe 64 is screwed with a fire extinguisher bottle 65 located in the stand; a second solenoid valve is provided on the auxiliary pipe.

[0039] A charging post and a plurality of evenly distributed lighting lamps 66 are provided on the right side wall of the stand 51 .

[0040] A vehicle blocking frame 67 is provided on the left side of the upper surface of the sinking plate 4 .

[0041] The method of use of the present invention is as follows:

[0042] In actual use, a groove can be opened on the ground, and then the sinking bin can be embedded in the groove, while the ground cover plate is flush with the ground and coplanar. When the electric car is parked, the electric car can be completely parked on the upper surface of the sinking plate 4.

[0043] In order to prevent the battery of the electric vehicle from being easily damaged, the battery of the electric vehicle is generally installed at the rear of the electric vehicle or the chassis of the electric vehicle. Once spontaneous combustion occurs, these two places of the electric vehicle will burn immediately. In order to extinguish the fire immediately, it is necessary to ensure that the water flow sprayed from the side water spray head 6 can be sprayed to the rear of the electric vehicle. At this time, the angle of the side water spray head can be adjusted. When the electric vehicle is parked, if the rear of the vehicle is opposite to the stand 51, the universal spray head 58 can be rotated by the side water spray head 6 to make the side water spray head 6 opposite to the front of the electric vehicle. Once the water flow is sprayed from the side water spray head 6, the water flow can It can be sprayed directly on the rear of the vehicle. If the front of the vehicle is opposite to the stand 51, it is necessary to rotate the universal nozzle 58 through the side nozzle 6 to make the side nozzle 6 tilt upward, so that the water flow sprayed from the side nozzle 6 can form a certain parabola, and finally pass over the top of the electric car and spray at the rear position of the vehicle away from the stand 51. The upper end of the side water pipeline 61 and the upper end of the auxiliary pipeline 64 are respectively connected to the front and rear ends of the universal nozzle 58, so it will not affect the upward or downward rotation of the universal nozzle 58. Under the intervention of external force, the universal nozzle 58 can rotate with the upper end of the side water pipeline 61 and the upper end of the auxiliary pipeline 64 as the center, so as to achieve universal angle adjustment.

[0044] When the electric vehicle spontaneously ignites, the smoke sensor 7 arranged on the upper surface of the sinking plate 4 and the right side wall of the stand 51 will sense the spontaneous combustion at the first time and feedback the information, and the first solenoid valve will be opened at the first time. At this time, the water flow in the water pipe connected to the water inlet pipe 62 will enter the hose 63 and the side water pipe 61 through the water inlet pipe 62 respectively, and the water flow entering the side water pipe 61 will enter the universal nozzle 58, and finally be sprayed out from the side water nozzle 6 and sprayed onto the rear of the electric vehicle to curb the spontaneous combustion. The water flow entering the hose 63 will pass through the lower water pipe 59 and the lower water spray pipe 60 in turn, and finally be sprayed out through the lower water spray hole 5 that is connected to the lower water spray pipe 60. Since the electric vehicle is completely stopped on the upper surface of the sinking plate 4, the water flow sprayed from the lower water spray hole 5 will be directly sprayed on the battery at the bottom of the vehicle, which can effectively prevent the spontaneous combustion of the vehicle chassis.

[0045] When the lower water spray hole 5 sprays water to prevent the chassis of the automobile from spontaneously igniting, the micro motor 49 of the limiting device starts to start. At this time, the motor shaft of the micro motor 49 drives the driving gear 50 to rotate, and the driving gear 50 is meshed with the meshing tooth 48. When the driving gear 50 rotates, the limiting block 44 rotates around the hinge point at its right end, and the upper left end of the limiting block 44 begins to gradually retract into the hidden cavity 43 through the hidden hole 45. At this moment, the spring 46 is compressed. When the limiting block 44 is completely hidden in the hidden cavity 43, the limiting block 44 no longer restricts the sliding shaft 14 from moving right. Under the weight of the electric vehicle, the inner angle of the inverted V-shaped structure formed by the first lifting arm 11 and the second lifting arm 13 gradually increases, and the sinking plate 4 sinks naturally.

[0046] When the sinking plate 4 moves downward, the sinking plate 4 will drive the upper hinge seat 19, the upper middle guide seat 9, and the upper right guide seat 21 to move downward. When the upper middle guide seat 9 moves downward, the upper middle hinge shaft 12 used to hinge the right end of the first lifting arm 11 and the left end of the second lifting arm 13 will move right along the upper middle guide hole 16 on the upper middle guide seat 9, and the sliding shaft at the right end of the second lifting arm 13 will move right along the trajectory of the lower right guide hole 18 on the lower right guide seat 10, and the sliding shaft 14 gradually approaches the push Block 35, at this time, the inner angle of the inverted V-shaped structure formed by the first lifting arm 11 and the second lifting arm 13 gradually increases, so that the sinking plate 4 can move down smoothly along the trajectory of the inner wall of the sinking bin 2. When the upper hinge seat 19 and the upper right guide seat 21 move down, the lower middle hinge shaft 23 for hingedly connecting the right end of the third lifting arm 22 and the left end of the fourth lifting arm 24 will move right along the trajectory of the lower middle guide hole 26 on the lower middle guide seat 20, and the upper right guide shaft 27 at the right end of the fourth lifting arm 24 will move along the upper right guide hole 26 on the lower middle guide seat 20. The trajectory of the upper right guide hole 29 on the right guide seat 21 moves to the right, and the inner angle of the V-shaped structure formed by the third lifting arm 22 and the fourth lifting arm 24 gradually increases. The existence of the supporting device will not affect the sinking action of the sinking plate 4, and the third lifting arm 22 and the fourth lifting arm 24 of the supporting device can add two supports on the basis of the first lifting arm 11 and the second lifting arm 13, thereby effectively improving the pressure bearing capacity of the sinking plate 4 and ensuring that the sinking plate 4 can withstand the weight of the electric vehicle. As the sinking plate 4 sinks, a water storage tank will be enclosed between the upper surface of the sinking plate 4 and the inner wall of the sinking bin 2. The water originally sprayed from the lower water spray hole 5 will fall into the water storage tank after spraying on the chassis of the car, and accumulate water. As the sinking plate 4 continues to sink, the chassis of the car will be completely submerged in the water in the water storage tank, further improving the fire extinguishing effect, and the existence of the hose 63 ensures that the lower water pipeline 59 and the lower water spray pipeline 60 can move with the sinking plate.

[0047] After the fire is extinguished, the smoke sensor 7 will detect it immediately and control the first solenoid valve to close. At this time, the lower water spray hole 5 and the side water spray head 6 stop spraying water, and the drive motor 32 is started at the same time. The motor shaft of the drive motor 32 starts to drive the drive wheel 33 to rotate, and the external thread 34 on the outer wall of the drive wheel 33 is meshed with the driven gears 39 on the front and rear sides. Therefore, when the drive wheel 33 rotates, the driven gear 39 rotates accordingly, thereby driving the screw rod 38 to rotate, and the lower surface of the push block 35 is in contact with the lower inner wall of the sinking bin 2. When the push block 35 tries to rotate, it will be restricted by the lower inner wall of the sinking bin 2, and the push block 35 cannot rotate with The screw rod 38 rotates, and the force of the screw rod 38 rotation will be converted into a force for the lateral movement of the pushing block 35. At this moment, under the rotation of the screw rod 38, the pushing block 35 moves to the left along the lower inner wall of the sinking bin 2. When the pushing block 35 moves to the left for a certain stroke, the sliding shaft 14 will be embedded in the pushing groove 36 on the left side of the pushing block 35. As the pushing block 35 continues to move to the left, the sliding shaft 14 will be pushed to the left. At this moment, the sliding shaft 14 moves to the right along the trajectory of the lower right guide hole 18, and the inner angle of the inverted V-shaped structure formed by the first lifting arm 11 and the second lifting arm 13 gradually becomes smaller. The sinking plate moves upward stably under the pushing of the right end of the first lifting arm 11 and the left end of the second lifting arm 13.

[0048] When the sinking plate 4 moves up, the upper hinge seat 19 and the upper right guide seat 21 move up accordingly, and the inner angle of the V-shaped structure formed by the third lifting arm 22 and the fourth lifting arm 24 gradually becomes smaller. When the first lifting arm 11, the second lifting arm 13, the third lifting arm 22 and the fourth lifting arm 24 are reset, the sinking plate 4 is reset accordingly. At the same time, the micro motor 49 of the limiting device is started again. Driven by the driving gear 50 and the elastic force of the spring 46, the limiting block 44 rotates upward with its own right end hinge point as the center, and the upper left end of the limiting block 44 gradually moves through the hidden hole 45 to above the hidden hole 45. At this moment, the limiting block 44 is on the right side of the end of the sliding shaft 14 and fits with the right side wall of the end of the sliding shaft 14. Under the limiting action of the limiting block 44, the position of the sliding shaft 14 is fixed, thereby fixing the positions of the first lifting arm 11 and the second lifting arm 13, and realizing the position fixing of the sinking plate 4 after the reset.

[0049] In summary, the present invention can spray water directly onto the chassis of the electric vehicle through the lower water spray hole 5, and spray water onto the rear of the electric vehicle through the side water spray head 6. Therefore, no matter whether the battery of the electric vehicle is installed at the rear of the vehicle or at the chassis of the vehicle, once spontaneous combustion occurs at these two locations, the smoke sensor 7 will sense it at the first time, and quickly extinguish the fire through the lower water spray hole 5 and the side water spray head 6. When the lower water spray hole 5 and the side water spray head 6 spray water, the sinking plate 4 will automatically sink, and the water sprayed from the lower water spray hole 5 will accumulate in the groove formed by the upper surface of the sinking plate 4 and the inner wall of the sinking bin 2. The accumulated water can directly submerge the chassis of the vehicle, and can continuously provide cooling for the battery that has spontaneously combusted, further shortening the fire extinguishing time and improving the fire extinguishing efficiency. Therefore, if spontaneous combustion occurs when the vehicle is parked and no one finds it, the fire can be automatically extinguished at the first time to avoid the situation where the explosion caused by the spontaneous combustion of the vehicle causes damage to the surrounding objects.

[0050] The ends of the front and rear ends of the universal sprinkler 58 that are not connected to the upper end of the side water pipe 61 are connected to the auxiliary pipe 64, and the lower end of the auxiliary pipe 64 is screwed with a fire extinguisher bottle 65 located in the stand 51. A second solenoid valve is provided on the auxiliary pipe 64. Corresponding fire extinguishing materials can be placed in the fire extinguisher bottle 65 in advance according to actual fire extinguishing needs. When special fire extinguishing materials are needed to extinguish the fire, the first solenoid valve will be closed, the side water pipe 61 and the lower water pipe 59 will stop passing water, the side water spray head 6 and the lower water spray hole 5 will stop spraying water, and the second solenoid valve will be opened accordingly. The fire extinguishing material in the fire extinguisher bottle 65 will pass through the auxiliary pipe 64 and the universal sprinkler 58 in turn, and finally be sprayed out from the side water spray head 6 to extinguish the fire of the electric vehicle. The front and rear sides of the left side wall of the stand 51 are provided with openings 52 that are connected to its internal space, and an opening and closing door 53 is hinged on one side of the opening 52. The existence of the opening and closing door 53 facilitates the disassembly and assembly of the fire extinguisher bottle and facilitates the maintenance of the internal components of the stand.

[0051] A charging pile and a number of evenly distributed lighting lamps 66 are provided on the right side wall of the stand 51. The presence of the charging pile can facilitate charging of the electric vehicle when parking, and the presence of the lighting lamps 66 can illuminate the environment near the parking space.

[0052] A car stop frame 67 is provided on the left side of the upper surface of the sinking plate 4. The existence of the car stop frame 67 enables the driver to clearly understand the accurate parking position. Once the wheel touches the car stop frame 67, the car can stop. At this time, the car is completely located on the sinking plate 4. At the same time, it can effectively prevent the car from hitting the vertical frame when parking, causing damage to the vertical fire extinguishing device.

[0053] In fact, not all of the water from the front and rear side sprinkler heads 6 is sprayed toward the rear of the car. One of the water streams can also be sprayed directly onto the body of the electric car, thereby cooling the body of the car and effectively preventing other unburned parts of the electric car from being damaged due to high temperature.
