Description

Technical Field

[0001] The invention relates to the technical field of fire prevention and extinguishing of electric bicycles, and in particular to a lifting type fire extinguishing device for electric bicycles. Background Art

[0002] Battery vehicles, also known as "electric bicycles", are pure electric vehicles that are powered by batteries (batteries) and driven by electric motors (DC, AC, series excitation, external excitation). The service life of battery vehicles is generally 8 to 12 years, and the service life of their batteries is generally 1 to 4 years (depending on usage and maintenance). As the use time of electric bicycles increases, the risk of fire increases when the battery ages, so fire extinguishing devices are needed to protect electric bicycles.

[0003] However, the fire extinguishing device of the existing electric bicycle often requires the user to actively operate it, and cannot be automatically started to extinguish the fire when the user leaves, so the safety performance is poor.

[0004] The reason why the battery car catches fire is that the lithium battery spontaneously ignites and generates huge energy, so once the battery car catches fire, ordinary carbon dioxide or dry powder fire extinguishers can only put out the surface fire. However, the internal battery continues to spontaneously ignite, so using carbon dioxide or dry powder fire extinguishers cannot completely extinguish the battery of the battery car. Summary of the invention

[0005] The purpose of the present invention is to provide a lifting type electric bicycle fire extinguishing device, which not only has the function of parking electric bicycles, but also can automatically lower the loading plate when it senses that the electric bicycle is on fire and there is no one on the loading plate, immersing the burning battery part in water, thereby extinguishing the fire source in the first time, improving the safety of electric bicycle use, and solving the problems raised by the above technical background.

[0006] To achieve the above-mentioned purpose, the present invention provides a lifting type electric bicycle fire extinguishing device, including a water tank with an opening on the top, a vehicle loading plate on the inner side of the water tank, and a lifting mechanism connected to the vehicle loading plate; it also includes a sensor device located on one side of the vehicle loading plate, and both the sensor device and the lifting mechanism are electrically connected to the control assembly.

[0007] As a further improvement of the present invention, the lifting mechanism is connected between the bottom of the vehicle loading plate and the bottom of the water tank; the lifting mechanism includes a first telescopic mechanism installed laterally at the bottom of the vehicle loading plate, and also includes a pair of second telescopic mechanisms, and the pair of two second telescopic mechanisms are symmetrically arranged at both ends of the first telescopic mechanism, one end of each second telescopic mechanism is rotatably connected to one end of the first telescopic mechanism, and the other end of the second telescopic mechanism is rotatably connected to the bottom of the water tank; both the first telescopic mechanism and the second telescopic mechanism are electrically connected to the control assembly.

[0008] As a further improvement of the present invention, the first telescopic mechanism includes a gear, a first rack and a second rack arranged opposite to each other, the gear is located between the first rack and the second rack, and the gear is respectively meshed with the first rack and the second rack; the gear is linked to a drive motor, and the drive motor is installed on the vehicle loading plate, and the control assembly includes a first controller electrically connected to the drive motor; a rack slide rail is also provided on the vehicle loading plate, and both the first rack and the second rack are slidably matched with the rack slide rail; one end of the first rack and the second rack are each rotatably connected to one end of the second telescopic mechanism.

[0009] As a further improvement of the present invention, the second telescopic mechanism is a hydraulic support device, which includes a hydraulic rod, and the lower end of the hydraulic rod is rotatably connected to the bottom of the water tank via a support base; a first connecting member is provided at the upper end of the hydraulic rod, and a second connecting member is provided at one end of the first rack and the second rack, and the first connecting member and the second connecting member are rotatably connected via a rotating shaft; the control assembly also includes a second controller electrically connected to the hydraulic rod.

[0010] As a further improvement of the present invention, water permeable holes are provided on the vehicle loading plate.

[0011] As a further improvement of the present invention, a water inlet and a water outlet are provided on the side wall of the water storage tank.

[0012] As a further improvement of the present invention, a water level detection device is provided on the side wall of the water storage tank.

[0013] As a further improvement of the present invention, the sensing device includes a temperature-sensing smoke sensor and an infrared human body detector, and both the temperature-sensing smoke sensor and the infrared human body detector are electrically connected to the control assembly.

[0014] Beneficial Effects

[0015] Compared with the prior art, the advantages of the lifting type electric bicycle fire extinguishing device of the present invention are:

[0016] 1. The smoke sensor senses the smoke generated by the battery of the electric bicycle, and the temperature sensor senses the temperature generated when the electric bicycle burns. When abnormal temperature and smoke are sensed, the infrared human body sensor is activated. When it detects that there is someone in the parking space, an alarm is issued, and after the person leaves the parking space, the vehicle carrier lowering program is automatically started to lower the burning electric bicycle into the water tank for soaking and extinguishing the fire. Compared with spray fire extinguishing, soaking fire extinguishing is faster and can block the spread of fire in the first time, thereby minimizing the fire loss;

[0017] 2. Without affecting the normal use of electric bicycle parking spaces, the underground space is used to provide fire prevention and fire extinguishing functions for electric bicycles. The burning electric bicycles are lowered into the water tank through the lifting mechanism to immerse and extinguish the fire. The structure is simple and the cost is low. Compared with fireproof devices such as fireproof partitions, it saves weight and space, and is more space-saving;

[0018] 3. Compared with traditional electric bicycle fire extinguishing methods and devices, this solution adopts immersion fire extinguishing, which causes less damage to the battery and has a faster immersion fire extinguishing speed. The induction automatic lifting device does not require manual operation, the operation process is simpler and more efficient, and the safety performance is higher.

[0019] 4. During normal use, rainwater can enter the water tank through the water holes on the vehicle carrier, which can save water resources to a certain extent and collect rainwater for fire fighting.

[0020] 5. The lifting mechanism includes a first telescopic mechanism installed horizontally at the bottom of the vehicle loading plate, and also includes a pair of second telescopic mechanisms. This lifting mechanism can be directly installed between the vehicle loading plate and the water tank, without occupying the space above the vehicle loading plate or below the water tank, and can ensure that the lifting stroke of the vehicle loading plate is as close as possible to the depth of the water tank, thereby saving equipment space and facilitating the rapid installation of the fire extinguishing device.

DETAILED DESCRIPTION

[0037] Embodiments of the present invention will now be described with reference to the accompanying drawings.

[0038] Example

[0039] The specific embodiments of the present invention are as follows Figures 1 to 12 As shown, a lifting type electric bicycle fire extinguishing device includes a water tank 3 with an opening on the top, a vehicle loading plate 4 is provided inside the water tank 3, and a lifting mechanism is connected to the vehicle loading plate 4. It also includes a sensor device 5 located on one side of the vehicle loading plate 4. Both the sensor device 5 and the lifting mechanism are electrically connected to the control assembly. The top opening of the water tank 3 is flush with the ground.

[0040] The lifting mechanism is connected between the bottom of the vehicle loading plate 4 and the bottom of the water tank 3. The lifting mechanism includes a first telescopic mechanism 2 installed transversely at the bottom of the vehicle loading plate 4, and both ends of the first telescopic mechanism 2 are telescopic ends. The lifting mechanism also includes a pair of support structures, and the two support structures are symmetrically arranged at both ends of the first telescopic mechanism 2. One end of each support structure is rotatably connected to one end of the first telescopic mechanism, and the other end of the support structure is rotatably connected to the bottom of the water tank 3. The first telescopic mechanism 2 is electrically connected to the control assembly.

[0041] Preferably, the supporting structure is a second telescopic mechanism, one end of each second telescopic mechanism is rotatably connected to one end of the first telescopic mechanism, and the other end of the second telescopic mechanism is rotatably connected to the bottom of the water tank 3. The second telescopic mechanism is electrically connected to the control assembly.

[0042] The lifting mechanism of this solution uses the first telescopic mechanism 2 and the second telescopic mechanism to achieve lifting. When the vehicle loading plate 4 is in a normal state, the second telescopic mechanism is arranged vertically; when the vehicle loading plate 4 is in a state of complete descent, the second telescopic mechanism is in a nearly horizontal state (there is always an angle between the second telescopic mechanism and the first telescopic mechanism 2 to ensure that the two will not be unable to rotate relative to each other due to being located in the same straight line when they are extended and retracted). Compared with directly using a vertically arranged telescopic structure to achieve lifting, the lifting mechanism of this solution occupies less space in the retracted state and can be lowered to a greater height.

[0043] In this embodiment, two first telescopic mechanisms 2 arranged in parallel are provided at the bottom of each vehicle loading plate 4 , and second telescopic mechanisms are provided at both ends of each first telescopic mechanism 2 .

[0044] The first telescopic mechanism 2 includes a gear 23, a first rack 24 and a second rack 25 arranged opposite to each other, the gear 23 is located between the first rack 24 and the second rack 25, and the gear 23 is respectively meshed with the first rack 24 and the second rack 25. The gear 23 is connected to the power output shaft of the drive motor 21, and the drive motor 21 is installed on the vehicle loading plate 4. The drive motor 21 drives the gear 23 to rotate forward and reverse, so as to drive the first rack 24 and the second rack 25 to telescopically move relative to the vehicle loading plate 4.

[0045] The control assembly includes a first controller 22 electrically connected to the drive motor 21. The vehicle loading plate 4 is also provided with rack rails 42, and the number of rack rails 42 corresponds to the number of racks. Both the first rack 24 and the second rack 25 are slidably matched with the rack rails 42. One end of each of the first rack 24 and the second rack 25 is rotatably connected to one end of a second telescopic mechanism.

[0046] Specifically, the second telescopic mechanism is a hydraulic support device 1, which includes a hydraulic rod 12. The lower end of the hydraulic rod 12 is rotatably connected to the bottom of the water tank 3 through a support base 11. The support base 11 is fixed to the bottom of the water tank 3, and the hydraulic rod 12 can rotate around the support base 11. The upper end of the hydraulic rod 12 is provided with a first connecting member 13, and one end of the first rack 24 and the second rack 25 are both provided with a second connecting member 26. The first connecting member 13 and the second connecting member 26 are rotatably connected through a rotating shaft 14, and the rotating shaft 14 passes through the first connecting member 13 and the second connecting member 26 at the same time. The control assembly also includes a second controller 15 electrically connected to the hydraulic rod 12. In this embodiment, four hydraulic support devices 1 are respectively located at the four corners of the vehicle loading plate 4.

[0047] The vehicle loading plate 4 is provided with a plurality of water permeable holes 41. In normal use, rainwater can enter the water storage tank 3 through the water permeable holes 41 on the vehicle loading plate 4, which can save water resources to a certain extent and collect rainwater as fire extinguishing water.

[0048] The side walls at both ends of the water storage tank 3 are respectively provided with a water inlet 31 and a water outlet 32. The side wall of the water storage tank 3 is also provided with a water level detection device 33.

[0049] The sensing device 5 includes a temperature and smoke sensor 51 and an infrared human detector 52, both of which are electrically connected to the control assembly. The sensing device 5 is installed on one side of the top opening of the water storage tank 3, and the control assembly can receive the wireless signal of the sensing device 5, thereby starting or shutting down the lifting mechanism.

[0050] like Figure 7 As shown in the schematic diagram of the implementation process of the fire extinguishing procedure, when the sensor device 5 detects that the electric bicycle 6 is on fire, the device runs the fire extinguishing procedure, the gear 23 rotates clockwise driven by the drive motor 21, the first rack 24 and the second rack 25 are retracted to the middle, and the hydraulic rod 12 rotates and extends around the support base 11 under the action of the first rack 24, the second rack 25 and the second controller 15, the loading plate 4 slowly descends, and the water inside the water tank 3 gradually covers the loading plate 4 through the water permeable hole 41.

[0051] like Figure 8 As shown in the schematic diagram of the completion of the fire extinguishing procedure, the hydraulic rod 12 has been rotated to a near horizontal position, the vehicle loading plate 4 has been lowered to the lowest point, and the water source inside the water tank 3 can flood the burning electric bicycle battery to achieve immersion fire extinguishing.

[0052] like Fig. 9As shown, in a normal state, the loading plate 4 is flush with the ground, which does not affect the normal use of the electric bicycle parking space, and rainwater can enter the water tank 3 through the water-permeable holes 41 on the loading plate 4, which can save water resources to a certain extent and collect rainwater for fire fighting. The inner wall of the water tank 3 has a water inlet 31 and a water outlet 32. A water level monitoring device 33 is installed near the water inlet 31. When the water for fire fighting in the water tank 3 is insufficient, a signal is sent out, so that water is replenished through the water inlet 31. In the rainy season, rainwater is collected into the water tank 3 through the water-permeable holes 41, and discharged through the water outlet 32 ​​when the water level is higher than the water outlet.

[0053] like Fig.10 , 11 As shown, after the fire extinguishing procedure is initiated, the vehicle loading plate 4 descends, and the water is squeezed by the vehicle loading plate 4 and penetrates through the water permeable holes 41. The vehicle loading plate 4 carrying the burning electric bicycle 6 descends to the bottom, and the water submerges the burning battery part of the electric bicycle 6, thereby achieving the purpose of immersion fire extinguishing.

[0054] like Fig.12 As shown, this is a situation where multiple devices of the lift-type electric bicycle fire extinguishing device are used in parallel in an actual scenario.

[0055] In addition to the above embodiments, the first telescopic mechanism may also adopt a hydraulic telescopic device, for example, a structure in which piston rods are provided at both ends of a hydraulic cylinder, wherein the hydraulic cylinder is mounted on the vehicle-carrying plate 4, and the left and right piston rods are respectively rotatably connected to the second telescopic mechanisms on both sides. The second telescopic mechanism may also adopt a linear motor structure. In addition, the support structure may also not have a telescopic function and only adopt an ordinary support rod, and the lifting and lowering of the vehicle-carrying plate 4 can also be achieved through the telescopic action of the two ends of the first telescopic mechanism and the swinging action of the support structure.

[0056] The present invention has been described above in conjunction with the best embodiments, but the present invention is not limited to the embodiments disclosed above, but should cover various modifications and equivalent combinations based on the essence of the present invention.
