Description

Technical Field

[0001] This invention relates to the field of fire truck technology, and in particular to a multi-functional new energy fire truck. Background Technology

[0002] New energy vehicles are now widely used, including pure electric vehicles (BEVs), plug-in hybrid electric vehicles (PHEVs), and hydrogen fuel cell electric vehicles (FCEVs). Compared with traditional fuel vehicles, they have many advantages, mainly in terms of environmental protection, economy, driving experience, and intelligence. Vehicles need to be charged at charging stations before their electric power is about to run out in order to ensure their range.

[0003] However, due to vehicle malfunctions or accidents, the vehicle itself may catch fire, or the charging station may catch fire while charging. Current technology typically uses fire trucks to extinguish fires. However, existing technology still has shortcomings. Ordinary fire trucks rely solely on water to extinguish the fire. While water can quickly suppress large fires, the complex internal circuitry of charging stations and the accelerant produced when lithium batteries come into contact with water after catching fire mean that traditional fire extinguishing methods often require large amounts of water.

[0018] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0019] Example 1: Reference Figures 1-10 A multifunctional new energy fire extinguisher includes: a vehicle body 1, a nozzle 2, a second nozzle 3, a pipe 4, a storage tank and a second storage tank. The vehicle body 1 is connected to the storage tank and the second storage tank. The storage tank stores multifunctional lithium battery agents, and the second storage tank stores water. The storage tank is connected to the end of the nozzle 2 through the pipe 4, and the second storage tank is connected to the second nozzle 3 through the second pipe. A liquid pump is connected to the pipe 4, and a second liquid pump is connected to the pipe 2.

[0020] The principle behind the above scheme is as follows: There are various reasons that can lead to fires in new energy vehicles while they are charging or parked. The fire may originate inside the vehicle or the charging station. The vehicle body 1 is connected to a storage tank and a storage tank 2. The storage tank is used to store multifunctional lithium battery agent, which is perfluorohexanone. The storage tank 2 is used to store water. When the fire truck is extinguishing a fire at a charging pile or a small fire at a new energy vehicle, the activated liquid pump outputs the multifunctional lithium battery agent through pipe 4 to nozzle 2, and then outputs it to the fire point through nozzle 2 to extinguish the fire, thereby improving the fire extinguishing speed. When extinguishing a large-area fire involving a new energy vehicle or charging station, the activated liquid pump 2 outputs water through pipe 2 to nozzle 2 3. The water sprayed from nozzle 2 3 extinguishes the large-area fire. Subsequently, a multi-functional lithium battery agent is used to completely extinguish the fire. The multi-functional lithium battery agent requires less dosage, saving money.

[0021] The beneficial effects of the above scheme are as follows: The vehicle is equipped with two storage tanks, one for storing multi-functional lithium battery extinguishing agent and the other for storing water. The two extinguishing agents can be sprayed out through nozzle 2 or nozzle 3 respectively. The multi-functional lithium battery extinguishing agent can quickly extinguish small fires, while water can suppress and reduce the area of ​​large fires. Finally, the fire can be completely extinguished by spraying the multi-functional lithium battery extinguishing agent. This not only increases the vehicle's functionality in fire extinguishing but also improves fire extinguishing efficiency.

[0022] Example 2: Reference Figures 1-10 The inner wall of the nozzle 2 end is threaded to the side wall of the output end of the pipe 4. The inner wall of the other end of the nozzle 2 is provided with a chamfer 5. The inner wall of the pipe 4 is connected to a connecting rod 6. The end of the connecting rod 6 away from the pipe 4 is connected to the end of a conical column 7. The diameter of the other end of the conical column 7 is larger than the diameter of its end. The side wall of the conical column 7 is set towards the chamfer 5. The output end of the defrosting mechanism in the pipe 4 is set towards the side wall of the conical column 7.

[0023] The principles and beneficial effects of the above scheme are as follows: When using multifunctional lithium battery agent for fire extinguishing, the spray range of the multifunctional lithium battery agent sprayed from nozzle 2 is adjusted to cover the fire point. When nozzle 2 is rotated forward, it moves towards the output end of pipe 4, thereby increasing the distance between chamfer 5 and conical column 7. The multifunctional lithium battery agent sprayed from nozzle 2 is columnar, implementing point-to-point fire extinguishing. When nozzle 2 is rotated backward, it moves away from the output end of pipe 4, thereby decreasing the distance between chamfer 5 and conical column 7. The multifunctional lithium battery agent sprayed from nozzle 2 is umbrella-shaped, implementing wide-area fire extinguishing. The connecting rod 6 set in the mechanism is connected to the inner wall of pipe 4, thereby providing a stable installation position for conical column 7 and improving the stability of nozzle 2 when spraying multifunctional lithium battery agent.

[0024] Example 3: Reference Figures 1-10 The defrosting mechanism includes: a porous ceramic tube 8, a blower, a heating wire, and a one-way valve. The porous ceramic tube 8 is connected to the pipe 4. The end of the porous ceramic tube 8 away from the side wall of the pipe 4 is connected to the output end of the blower. The blower is connected to the vehicle body 1. The heating wire is connected inside the porous ceramic tube 8. The one-way valve is connected to the inner wall of the output end of the porous ceramic tube 8. The output end of the porous ceramic tube 8 is set towards the side wall of the conical column 7.

[0025] The principles and beneficial effects of the above scheme are as follows: The boiling point of the multi-functional lithium battery agent is 49.2°C. During fire extinguishing, the agent at nozzle 2 will be exposed to heat radiation from the fire point, resulting in an even higher temperature. Furthermore, the agent is affected by high pressure and moisture in the air or the agent itself during spraying. Therefore, under these conditions, the agent sprayed from nozzle 2 may experience flash evaporation, carrying away a significant amount of heat and causing frost formation on nozzle 2. This frost formation increases the risk of clogging, ultimately preventing nozzle 2 from spraying effectively. Although this can be mitigated in pipelines... A pressure relief valve is installed on pipe 4 to prevent the pipe 4 or nozzle 2 from rupturing due to excessive pressure. However, at this time, the nozzle 2 material may still be catalyzed due to large-area frost, and the fire extinguishing agent may not be sprayed during fire extinguishing, delaying the fire extinguishing opportunity. Therefore, a porous ceramic tube 8 is connected to pipe 4, and an electric heating wire is connected to the inner wall of the porous ceramic tube 8. When defrosting, the electric heating wire is powered, and the air pump is started to supply high-pressure air to the porous ceramic tube 8. The heated high-pressure air is sprayed through the output end of the porous ceramic tube 8 to the side wall of the conical column 7 and the chamfer 5, so as to quickly and efficiently defrost using high temperature and high pressure air. The one-way valve allows high-temperature and high-pressure air to be output through the porous ceramic tube 8 during defrosting. When defrosting is not in progress, i.e., when there is no multi-functional lithium battery agent flowing in the pipe 4 or when there is multi-functional lithium battery agent flowing, no multi-functional lithium battery agent will enter the porous ceramic tube 8, and no foreign objects will be allowed to enter the interior of the porous ceramic tube 8. The porous ceramic tube 8 can prevent the heat of the heating wire from dissipating into the pipe 4, and the porous ceramic tube 8 has excellent heat preservation effect.

[0026] Example 4: Reference Figures 1-10 The nozzle 2 3 includes: a pipe assembly 9, an arc blade 10 and a fan-shaped disk 11. The pipe assembly 9 is rotatably connected to the vehicle body 1. The end of the pipe assembly 9 is connected to the output end of the second pipe. The pipe assembly 9 is connected to the inner wall of the sealing ring 12 through the drive mechanism 23. The side wall of the sealing ring 12 contacts and cooperates with the inner wall of multiple arc blades 10. Multiple arc blades 10 are arranged in a circumferential array to form a sealing tube. The sealing tube is coaxially arranged with the pipe assembly 9.

[0027] The inner wall of the arc plate 10 away from the output end of the pipe assembly 9 is connected to the arc-shaped side wall of the fan-shaped disk 11. Multiple fan-shaped disks 11 are arranged in a circumferential array to form a sealing disk. The sealing disk and the sealing pipe form a sealing element to protect the output end of the pipe assembly 9. The other end of the arc plate 10 is connected to a rotating shaft 13, which is connected to the drive mechanism 23.

[0028] The principles and beneficial effects of the above scheme are as follows: Pipe assembly 9 is connected to the output end of pipe 2 for spraying water. Pipe assembly 9 is rotatably connected to vehicle body 1. Therefore, when using water to extinguish a fire, the operator can rotate pipe assembly 9 so that its output end is directed toward the fire. After the fire is extinguished, the arc plates 10 arranged in a circular array form a sealing tube. The inner wall of the sealing tube contacts and fits with the side wall of the sealing ring 12. The inner wall of the arc plates 10 is connected to the arc side wall of the fan-shaped disk 11. Multiple fan-shaped disks 11 arranged in a circular array form a sealing disk. The sealing disk and the sealing tube form a sealing element. The sealing structure formed by the sealing element and the sealing ring 12 protects the output end of the pipe assembly 9. Therefore, when the vehicle is not working, foreign objects from the outside will not enter the output end of the pipe assembly 9. Although the output end of the pipe assembly 9 can be made of rust-proof metal in the prior art, or a rust-proof coating can be sprayed on the output end of the pipe assembly 9, there is still a risk that the coating of the pipe assembly 9 will be damaged after high-pressure water spraying. As a result, after the fire is extinguished, the moisture from the outside will still cause the pipe assembly 9 to rust. Therefore, a sealing structure is set to prevent moisture or corrosive liquids in the environment from causing rust or corrosion to the pipe assembly 9. The rotating shaft 13 can be rotated by the drive mechanism 23. Therefore, when fire extinguishing is required, the arc plate 10 can be rotated by the drive mechanism 23 to expose the output end of the pipe assembly 9 to the environment so as to spray water. After the fire is extinguished, the drive mechanism 23 is restarted. The drive mechanism 23 drives the rotating shaft 13 to rotate in the opposite direction, causing the arc plate 10 to rotate in the opposite direction, thereby restoring the structure of the sealing pipe and protecting the pipeline assembly 9 again.

[0029] Example 5: Reference Figures 1-10 The inner wall of the output end of the pipe assembly 9 is provided with a chamfer 15. A spline sleeve 16 is threadedly connected to the inner wall of the pipe assembly 9. The end of the spline sleeve 16 is slidably connected to the end of the spline shaft 17. The spline shaft 17 is rotatably connected to the inner wall of the pipe assembly 9. The other end of the spline shaft 17 is connected to a bevel gear 18 and a bevel gear 19. The bevel gear 19 is connected to the end of a rotating shaft 20. The rotating shaft 20 is rotatably connected to the pipe assembly 9. The end of the rotating shaft 20 away from the side wall of the pipe assembly 9 is connected to the end of an adjusting rod 21.

[0030] The other end of the spline sleeve 16 is connected to the end of the tapered column 22. The sidewall of the tapered column 22 is set towards the chamfer 15, and the diameter of the other end of the tapered column 22 is larger than the diameter of its end.

[0031] The principles and beneficial effects of the above scheme are as follows: When it is necessary to adjust the water status at the output end of the pipe assembly 9, the forward rotation adjustment rod 21 drives the rotating shaft 20 to rotate forward, and the synchronous rotation of the bevel gear 19 drives the bevel gear 18 connected to it to rotate. The spline shaft 17 rotates synchronously, and the spline sleeve 16 rotates at the same time, and drives the conical column 22 to move away from the chamfer 15. At this time, the water sprayed from the output end of the pipe assembly 9 is in columnar shape and can be used for point-to-point fire extinguishing. The reverse adjustment rod 21 drives the rotating shaft 20 to reverse, and the synchronous bevel gear 29 reverses, driving the bevel gear 18 connected to it to rotate. The spline shaft 17 rotates synchronously, and the spline sleeve 16 rotates at the same time, driving the conical column 22 to move towards the chamfer 15. At this time, the water sprayed from the output end of the pipeline assembly 9 is umbrella-shaped and can carry out large-area fire extinguishing. The adjusting rod 21 is set perpendicular to the rotating shaft 20, which reduces the difficulty of adjusting the rotation of the rotating shaft 20.

[0032] Example 6: Reference Figures 1-10 The drive mechanism 23 includes a gear 14 and a sleeve 24. The sleeve 24 is rotatably connected to the side wall of the pipe assembly 9. Multiple sliding grooves 25 are opened through the side wall of the sleeve 24. The sliding grooves 25 are parallel to the axis of the pipe assembly 9. Multiple helical sliding grooves 26 are opened on the side wall of the pipe assembly 9. The bottom end of the sliding rod 27 is slidably connected in the helical sliding groove 26. The middle part of the sliding groove 25 is slidably connected to the sliding rod 27. The bottom end of the rack 28 is connected to the top of the sliding rod 27. The top end of the rack 28 is meshed with the gear 14. The gear 14 is connected to the rotating shaft 13. The rack 28 is connected to the sealing ring 12 through the spring 29.

[0033] The principles and beneficial effects of the above scheme are as follows: The spiral groove 26 is inclined to the axis of the pipe assembly 9, based on the attached... Figure 8 It can be seen that the spiral groove 26 is defined as right-handed, starting from one end of the spiral groove 26 away from the sector disk 11 and ending at the other end. When the sealing pipe needs to be opened, that is, when multiple arc plates 10 are rotated in the positive direction and set perpendicular to the pipe assembly 9, first rotate the sleeve 24 clockwise, that is, to the right. Under the sliding matching of the sliding groove 25 and the sliding rod 27, and the sliding cooperation of the sliding rod 27 and the spiral sliding groove 26, the sliding rod 27 drives the rack 28 to move towards the sector disk 11, and the spring 29 is compressed. At the same time, the gear 14 meshing with the rack 28 rotates clockwise. Under the rotational cooperation of the sleeve 24 and the rotating shaft 13, the gear 14 drives the rotating shaft 13 and the arc plate 10 to rotate in the positive direction, that is, clockwise, and finally opens the arc plate 10, ending its protection of the output end of the pipe assembly 9. At this time, water can be sprayed from the output end of the pipe assembly 9 to extinguish the fire. Once opened, the arc plate 10 is positioned in front of the user, protecting the user's hands and preventing injury from explosives in the fire point of the new energy vehicle or charging station during firefighting, thus improving the user's safety during firefighting. The arc-shaped piece 10, which is opened and perpendicular to the top of the pipe assembly 9, can be used by the user to aim at the fire point when extinguishing a fire. Since the power to the charging station is cut off before using the pipe assembly 9 to extinguish the fire, continuous use of the pipe assembly 9 to output water will not cause electric shock to the user, and the user has sufficient means to prevent electric shock when extinguishing the fire. When the sealing tube needs to be closed, that is, when multiple arc plates 10 are rotated in opposite directions and set parallel to the pipe assembly 9, first rotate the sleeve 24 counterclockwise, that is, to the left. Under the sliding matching of the slide groove 25 and the sliding rod 27, and the sliding cooperation of the sliding rod 27 and the spiral slide groove 26, the sliding rod 27 drives the rack 28 to move away from the sector disk 11, and the spring 29 returns to its original position. At the same time, the gear 14, which meshes with the rack 28, rotates counterclockwise. Under the rotational cooperation of the sleeve 24 and the rotating shaft 13, the gear 14 drives the rotating shaft 13 to rotate in the opposite direction to the arc plate 10, that is, counterclockwise, and finally closes the arc plate 10. It then begins to cooperate with the sector disk 11 to protect the output end of the pipe assembly 9. At this time, it can prevent external water, dust or corrosive substances from adhering to the output end of the pipe assembly 9, and provide efficient protection for the pipe assembly 9, reduce the inspection and maintenance time of the pipe assembly 9 before use, reduce the cost of parts replacement and reduce the cost of labor.

[0034] Example 7: Reference Figures 1-10 The pipe assembly 9 has an annular groove 30 on its side wall. The end face of the annular groove 30 away from the fan-shaped disk 11 has a plurality of locking grooves 31 arranged in a circular array. The locking grooves 31 are inserted into the end of the arc-shaped locking block 32. The arc-shaped locking block 32 is slidably engaged with the annular groove 30. The top of the arc-shaped locking block 32 is connected to a connecting block 33. The end of the connecting block 33 facing the fan-shaped disk 11 is provided with a chamfer 34. The chamfer 34 is slidably engaged with the bottom of the pressure rod 35. The pressure rod 35 is slidably connected to the sleeve 24. The top of the pressure rod 35 is connected to a button 36. The bottom of the button 36 is connected to the side wall of the sleeve 24 through a spring 37. The other end of the connecting block 33 is connected to the sleeve 24 through a spring 38.

[0035] The principles and beneficial effects of the above scheme are as follows: During the rotation of sleeve 24, the user first presses down button 36, spring 2 37 is compressed, and after the pressure rod 35 at the bottom of button 36 contacts the chamfer 34 of connecting block 33, connecting block 33 drives arc-shaped locking block 32 to disengage from locking groove 31. Since the length of annular groove 30 along the axis of pipe assembly 9 is greater than the length of arc-shaped locking block 32 along the axis of pipe assembly 9, spring 3 38 is compressed. At this time, rotating button 36 causes sleeve 24 to rotate synchronously. After the rotation ends, releasing button 36 synchronously resets spring 2 37 and resets pressure rod 35. Pressure rod 35 ends contact with chamfer 34. Under the elastic force of spring 3 38 resetting, arc-shaped locking block 32 engages with another locking groove 31 to begin locking sleeve 24. The mechanism is designed with an annular groove 30 and multiple locking grooves 31 arranged in a circular array on the end face of the annular groove 30 away from the sector disk 11. This facilitates locking of the sleeve 24 by interlocking the locking grooves 31 with the arc-shaped locking block 32, thereby improving the stability during locking and reducing the difficulty of unlocking the sleeve 24.

[0036] Example 8: Reference Figures 1-10 The pipe assembly 9 is connected to a filter screen 39. A ball valve 40 is provided between the filter screen 39 and the bevel gear 18. The ball valve 40 is in a rotating and sealing fit with the pipe assembly 9. An air inlet pipe 41 is provided between the ball valve 40 and the bevel gear 18. The end of the air inlet pipe 41 is connected to the inner wall of the pipe assembly 9. A backwash pipe 42 is provided between the ball valve 40 and the filter screen 39. The end of the backwash pipe 42 is connected to the inner wall of the pipe assembly 9. The end of the drain pipe 43 is connected to the inner wall of an arc plate 10. A one-way valve 2 is connected inside the drain pipe 43. Multiple blades 44 are connected inside the backwash pipe 42. The blades 44 are connected to a rotating shaft 2 45. The end of the rotating shaft 2 45 that extends to the side wall of the backwash pipe 42 is connected to the input shaft of the air pump 2 46. The air pump 2 46 is connected to the air inlet pipe 41.

[0037] The backwash pipe 42 is connected to a one-way valve 3.

[0038] The principles and beneficial effects of the above scheme are as follows: When the pipe assembly 9 sprays water, the ball valve 40 needs to be opened. When opened, the ball valve 40 can be driven to rotate forward by the handwheel in the prior art. The filter screen 39 in the pipe assembly 9 can filter and intercept impurities in the water. When the device stops spraying water, the ball valve 40 is driven to rotate backward by the handwheel in the prior art to close the pipe assembly 9. At this time, since there are impurities attached to the filter screen 39, backwashing is required. During backwashing, the backwash water provided in the backwash pipe 42 cleans the filter screen 39. When the mechanism is extinguishing a fire, the one-way valve 3 in the backwash pipe 42 is closed to prevent pressure loss in the pipe assembly 9. After the ball valve 40 is closed, the filter screen 39 is backwashed. The backwash water drives the rotating shaft 45 to rotate through the blade 44, which in turn drives the air pump 46 to work, allowing outside air to enter the interior of the pipe assembly 9 through the air inlet pipe 41. According to the existing technology, the air inlet pipe 41 is connected to a filter screen structure to prevent impurities from entering the interior of the pipe assembly 9 when air is supplied to the output end of the pipe assembly 9. After the air output from the air inlet pipe 41 enters the interior of the pipe assembly 9, it begins to dry the output end and blows out some of the fire water remaining in the pipe assembly 9 into the seal. Since a drain pipe 43 is connected to an arc plate 10, the flowing air and residual water can be discharged through the one-way valve 2 in the drain pipe 43. Based on the rationality of the device design, the drain pipe 43 is set perpendicular to the bottom of the pipe assembly 9. When the one-way valve 2 is not draining or venting, it can provide sealing protection for the interior of the seal. The device is designed to perform backwashing and drying simultaneously, which reduces the power requirements and can thoroughly dry the output end of the pipe assembly 9, keeping it dry. Since there is a chance that residual harmful smoke from the fire scene may enter the sealing element when the sealing element is used to seal the output end of the pipe assembly 9 after the fire extinguishing is completed, drying the pipe assembly 9 inside the sealing element can further prevent its output end from being damaged by harmful smoke or harmful substances. After the water spraying is finished, the pipe assembly 9 is sealed by the ball valve 40, which also prevents residual water in pipe 2 from entering the dried pipe assembly 9, further maintaining the drying effect of the mechanism on its output end.
