Description

Technical Field

[0001] This invention relates to the field of fire extinguishing technology, and in particular to a smart three-band open flame detection device for rapid fire extinguishing of electric bicycle charging stations. Background Technology

[0002] Electric bicycle charging stations, as an important component of urban public transportation infrastructure, primarily serve to provide power to electric bicycles. The three-band infrared open flame detection module is a highly reliable and interference-resistant fire detection device. By simultaneously monitoring the radiation energy of three specific infrared wavelengths, it accurately identifies real flames, effectively eliminates environmental interference, and promptly detects open flames.

[0003] In existing charging station layouts, charging spaces are often arranged in a high-density, compact manner. This layout results in a lack of necessary physical fire-prevention distances between vehicles. If any electric vehicle catches fire, the lithium battery will ignite violently within seconds to tens of seconds. Neighboring vehicles will not have time to move, and the high-temperature heat radiation and open flames from the burning vehicle will quickly bake and ignite the battery packs of adjacent vehicles, easily triggering a chain reaction of explosions. Furthermore, the nozzle positions, spray angles, and coverage areas of existing charging station fire extinguishing devices are usually fixed. In actual fire scenarios, flames may occur under the vehicle chassis, inside the battery compartment, etc. Fixed nozzles have a small spray trajectory coverage area, easily creating blind spots during use. The extinguishing medium cannot easily penetrate the flame barrier to reach the core of the fire, thus reducing extinguishing efficiency.

[0004] Therefore, this application provides an intelligent three-band open flame detection and rapid fire extinguishing device for electric bicycle charging stations to meet the requirements. Summary of the Invention

Each gear is meshed with a rack, which is slidably connected to the inner rear wall of the sliding groove at the top of the mounting box. A baffle is fixedly connected to the rack via a lower connecting strip, and the baffle is vertically slidably installed inside the sliding groove at the top of the mounting box.

[0008] Preferably, a connecting pipe is installed at the top of the baffle, and the outer port of the connecting pipe is connected to the electrically controlled valve on the fire extinguisher port through a hose. A top spraying assembly is provided on the inner side of the connecting pipe, and the top spraying assembly is used for back-and-forth swing spraying of the extinguishing medium.

[0009] Preferably, the top spraying assembly includes multiple connecting brackets, which are equidistantly slidably installed in the mounting groove inside the connecting pipe. The multiple connecting brackets are rotatably connected to a rotating ball via connecting columns on the upper and lower sides. A second spray nozzle is passed through the rotating ball. The rotating ball is rotatably and sealed in a circular hole on the outer side of the connecting pipe. An adjustment assembly is provided between the connecting pipe and the mounting box. The adjustment assembly is used to adjust the position of the connecting brackets.

[0010] Preferably, the adjustment assembly includes a connecting rod and a mounting plate. The mounting plate is fixedly connected to the front side of the top of the mounting box. An abutment plate is slidably installed in the positioning groove on the rear side of the mounting plate via an electric push rod. The electric push rod is connected to a gravity sensor via an electrical signal. The rear end of the connecting rod is slidably installed inside the connecting tube via a spring. The front end of the connecting rod slides through the connecting tube in a sealed manner. The front end of the connecting rod slides against the abutment plate. Multiple push plates are equidistantly installed on the outer side of the connecting rod. The push plates are fixedly connected to the connecting frame at the corresponding position.

[0011] Preferably, the nozzle is angled downwards at two angles, the contact plate is designed with a wave-shaped structure, the wave-shaped structure of the contact plate is used for the sliding contact of the connecting rod, and the number of push plates corresponds to the number of connecting frames.

[0012] Preferably, the oscillating assembly includes two gears and multiple racks. The two gears are symmetrically fixedly installed on the outside of the nozzle shaft. The outer teeth of the two gears mesh with the racks. The multiple racks are symmetrically and equidistantly installed on the inner walls of both sides of the arc-shaped groove. Multiple nozzles are installed on the top of the nozzle. The bottom port of the nozzle is connected to the electrically controlled valve on the fire extinguisher port through a hose.

[0015] Compared with the prior art, the present invention has at least the following beneficial effects: In the above solution, by setting up a fireproof component, when the three-band infrared flame sensor detects a flame signal, the motor drives the rotating shaft to rotate, thereby causing the base plate and placement plate to rotate downwards, so that the burning electric bicycle enters the groove of the mounting box, achieving physical isolation of the combustion source. At the same time, the rotation of the rotating shaft drives the gear to rotate synchronously, driving the meshing rack to move upwards along the sliding groove, thereby driving the baffle to rise synchronously. The rise of the baffle forms a physical barrier, preventing the flame from bursting out and igniting nearby vehicles or facilities, achieving physical isolation between the combustion source and the surrounding environment, cutting off the path of the flame to nearby vehicles, and reducing property damage.

[0016] In the above scheme, by setting up a swing assembly, a top spray assembly, and an adjustment assembly, as the baffle rises, the second nozzle on the connecting pipe rises synchronously and sprays downwards. At the same time, the connecting rod rises and slides along the wave-shaped contact plate to generate reciprocating displacement, driving the second nozzle to deflect at an angle, increasing the spray range of the second nozzle, reducing fire extinguishing blind spots, and facilitating automatic adjustment of the deflection amplitude of the second nozzle based on the vehicle weight detected by the gravity sensor to expand the coverage area and improve the targeting of fire extinguishing. The rotation of the base plate drives the spray pipe to move along the arc-shaped groove, causing the second gear to mesh with the staggered rack second to generate reciprocating rotation, thereby driving the first nozzle to swing and spray, making it easier for the fire extinguishing medium to cover all corners of the bottom of the electric bicycle, including the bottom of the frame, the lower part of the battery compartment, and other areas, to improve the uniformity of fire extinguishing.

[0019] To further illustrate the technical means and effects of the present invention in achieving its intended purpose, the following detailed description of the specific implementation methods, structures, features, and effects of the present invention, in conjunction with the accompanying drawings and preferred embodiments, is provided below.

[0020] like Figures 1 to 13As shown, an embodiment of the present invention provides a smart three-band open flame detection electric bicycle charging pile rapid fire extinguishing device, comprising: a mounting box 1, which is installed in a ground pit; a charging pile body 2 is installed on the top of the mounting box 1; a charging socket 21 is installed on the top of the charging pile body 2; a three-band infrared flame sensor 22 is installed on the outside of the charging pile body 2; a fire extinguisher is installed in the cavity below the charging pile body 2; a base plate 3 is rotatably connected to the groove on the top of the mounting box 1 via a rotating shaft 11; the mounting box 1 is rotatably connected to the rotating shaft 11 via an external motor; and a fire extinguisher is installed on the top of the base plate 3. The mounting plate 4 has two mounting slots at the top, front and back, each equipped with a gravity sensor. An electric gripper 41 is mounted on top of each gravity sensor. Sliding grooves are provided on both sides of the top of the mounting box 1. A fireproof component 5 is installed between the two sliding grooves and the rotating shaft 11 to block flames. Arc-shaped grooves are provided on both sides of the inner wall of the mounting box 1. A nozzle 31 is rotatably mounted in the central strip hole of the bottom plate 3. A swing component 6 is provided between the two arc-shaped grooves and the nozzle 31 to adjust the position of the nozzle 31. The user pushes the electric bicycle onto the mounting plate 4 and... After the bicycle is moved to the designated location, the electric gripper 41 automatically clamps the wheels to secure the vehicle. The user starts charging by scanning a code, and the charging socket 21 begins to supply power. The three-band infrared flame sensor 22 accurately identifies real flames by simultaneously monitoring the radiation energy of three specific infrared wavelengths, effectively eliminating environmental interference and achieving high sensitivity and low false alarm rate fire detection. During the charging process of the electric bicycle, the three-band infrared flame sensor 22 continuously scans and monitors the environment around the charging pile 2, collects infrared radiation data in real time, and transmits it to the external controller for analysis. When the three-band infrared flame sensor 22 detects a radiation signal that matches the characteristics of a flame, the controller determines that a fire has occurred and immediately cuts off the power to the charging socket 21 to prevent the risk of electric shock and the spread of the fire. At the same time, the controller controls the motor to start, and the motor drives the rotating shaft 11 to rotate. The rotation of the rotating shaft 11 causes the base plate 3 and the placement plate 4 to rotate downwards by a certain angle, thereby moving the electric bicycle into the groove on the top of the mounting box 1 along with the placement plate 4, realizing the physical isolation of the combustion source from the surrounding environment, cutting off the path of the flame to nearby vehicles, and reducing property damage.

[0021] The fireproof assembly 5 includes two gears 51, which are symmetrically fixedly installed on the outside of the rotating shaft 11. The gears 51 are meshed with a rack 52, which is slidably connected to the rear wall of the sliding groove at the top of the mounting box 1. A baffle 53 is fixedly connected to the rack 52 via a lower connecting strip. The baffle 53 is vertically slidably installed inside the sliding groove at the top of the mounting box 1. In normal charging mode, the rotating shaft 11 is stationary, the gears 51 do not rotate, and the rack 52 and the connected baffle 53 are located at the initial bottom position of the sliding groove. When the three-band infrared flame sensor 22 detects a fire signal... An external controller starts the motor, which drives the rotating shaft 11 to rotate, thereby causing the base plate 3 and the placement plate 4 to rotate downwards, allowing the burning electric bicycle to enter the groove of the mounting box 1. At the same time as the rotating shaft 11 rotates, the gear 51 fixed on its outer side rotates synchronously. The rotation of the gear 51 drives the rack 52 to move upwards along the rear side wall of the sliding groove through meshing. Since the rack 52 is fixedly connected to the baffle 53 through the connecting strip, the baffle 53 is also lifted upwards synchronously. The upward movement of the baffle 53 effectively prevents the flames from escaping and igniting surrounding items, improves the flame blocking effect, and suppresses the further spread of the fire.

[0022] A connecting pipe 54 is installed at the top of the baffle 53. The outer port of the connecting pipe 54 is connected to the electrically controlled valve on the fire extinguisher port via a hose. A top spraying assembly 7 is installed inside the connecting pipe 54. The top spraying assembly 7 is used for back-and-forth swing spraying of the extinguishing medium. The initial installation position of the placement plate 4 and the highest point of the connecting pipe 54 is horizontal. As the baffle 53 rises, the connecting pipe 54 and the top spraying assembly 7 installed at the top of the baffle 53 rise synchronously. At this time, the fire extinguisher is activated, and the extinguishing medium inside enters the connecting pipe 54 through the hose. After the medium gathers in the connecting pipe 54, it is guided to the top spraying assembly 7, which facilitates the extinguishing medium to cover the burning electric bicycle in the groove from above. This top-down spraying method facilitates direct coverage of the vehicle top, the battery compartment top, and the hot airflow above the flames, forming an encircling fire extinguishing situation and effectively cutting off the radiation of the flames.

[0023] The top spraying assembly 7 includes multiple connecting brackets 71, which are equidistantly slidably installed in the mounting groove inside the connecting pipe 54. The multiple connecting brackets 71 are rotatably connected to rotating balls 72 via connecting columns on the upper and lower sides. The rotating balls 72 have nozzles 73 passing through them. The rotating balls 72 are sealed and rotatably installed in the outer circular hole of the connecting pipe 54. An adjustment assembly 8 is provided between the connecting pipe 54 and the mounting box 1. The adjustment assembly 8 is used to adjust the position of the connecting brackets 71. The high-pressure extinguishing medium in the fire extinguisher flows into the connecting pipe 54 through the hose and is finally sprayed out from the multiple nozzles 73, so that the extinguishing medium covers the electric bicycle from directly above, achieving three-dimensional spraying fire extinguishing.

[0024] Adjustment assembly 8 includes a connecting rod 81 and a mounting plate 82. The mounting plate 82 is fixedly connected to the front of the top of the mounting box 1. An abutment plate 83 is slidably installed in the positioning groove on the rear side of the mounting plate 82 via an electric push rod. The electric push rod is connected to the gravity sensor via an electrical signal. The rear end of the connecting rod 81 is slidably installed inside the connecting tube 54 via a spring. The front end of the connecting rod 81 slides through the connecting tube 54 in a sealed manner. The front end of the connecting rod 81 abuts and slides against the abutment plate 83. Multiple push plates 84 are equidistantly installed on the outer side of the connecting rod 81. The connecting rod 81 is fixedly connected to the corresponding connecting bracket 71. When a fire occurs, the baffle 53 drives the connecting pipe 54 to move upward along the sliding groove, and the connecting rod 81 rises synchronously. During the upward movement of the connecting rod 81, the front end of the connecting rod 81 contacts the fixed abutment plate 83. As the connecting pipe 54 continues to rise, the abutment plate 83 exerts a backward squeezing force on the connecting rod 81, forcing the connecting rod 81 to overcome the spring force and slide backward. The backward movement of the connecting rod 81 drives the push plate 84 to move synchronously, and the push plate 84 drives the connecting bracket 71 to move in the same direction. The pipe 54 slides within the pipe, which in turn drives the rotating ball 72 to rotate via the connecting column, causing the nozzle 73 to deflect at an angle, thereby increasing the spray range of the nozzle 73 and reducing blind spots in fire suppression. During the vehicle parking phase, a gravity sensor monitors the weight of the electric bicycle in real time. When the gravity sensor detects that the vehicle is heavy, the controller instructs the electric push rod to move. The electric push rod pushes the contact plate 83 backward, thereby changing the initial contact position between the contact plate 83 and the connecting rod 81. At this time, when the connecting pipe 54 rises for fire isolation, the... The increased contact stroke between the connecting rod 81 and the contact plate 83 causes the connecting rod 81 to move further backward. This greater displacement is transmitted to the connecting frame 71 through the push plate 84, causing the nozzle 73 to deflect at a larger angle, thereby obtaining a wider spray coverage area to meet the needs of larger fire sources. Therefore, for heavy vehicles, the nozzle 73 automatically expands the spray range to ensure that the extinguishing medium covers a larger burning area, thereby improving the targeting and efficiency of fire extinguishing. The heavier the vehicle, the larger the spray range of the nozzle 73.

[0025] The nozzle 73 is angled downwards, and the contact plate 83 is designed with a wave-shaped structure. The wave-shaped structure of the contact plate 83 is used for the sliding contact of the connecting rod 81. The number of push plates 84 corresponds to the number of connecting frames 71. The nozzle 73 is angled downwards to facilitate downward coverage of the surface of the burning material. The number of push plates 84 corresponds to the number of connecting frames 71 to ensure that each connecting frame 71 can be subjected to independent and synchronous driving force.

[0026] The oscillating assembly 6 includes two gears 61 and multiple racks 62. The two gears 61 are symmetrically fixed on the outer side of the nozzle 31 shaft, and their outer teeth mesh with the racks 62. The multiple racks 62 are symmetrically and equidistantly installed on the inner walls of the arc-shaped groove. Multiple nozzles 32 are mounted on the top of the nozzle 31, and the bottom port of the nozzle 31 is connected to an electrically controlled valve on the fire extinguisher port via a hose. As the base plate 3 rotates, the nozzle 31 moves accordingly. Since the gears 61 are fixed on the outer side of the nozzle 31 shaft, they move along the arc-shaped groove. When the gears 61 move along the arc-shaped groove, their teeth intermittently mesh with the racks 62 fixed on the inner walls of the arc-shaped groove. Because the racks 62 are fixed, the gears 61 are forced to rotate as they roll along the racks 62. The rotation of the gears 61 is transmitted through the nozzle 31 shaft. The nozzle 31 is handed over, which in turn causes the nozzle 31 and the nozzle 32 to rotate. The rotation of the nozzle 32 causes the sprayed extinguishing medium to no longer be sprayed at a fixed point, but to form a fan-shaped spray coverage area, expanding the coverage area of ​​the nozzle 32. With the continuous tilting of the base plate 3 and the continuous rotation of the nozzle 32, the extinguishing medium can continuously cover all corners of the bottom of the electric bicycle, including the bottom of the frame, the lower part of the battery compartment, etc., to improve the uniformity of extinguishing. Multiple racks 62 are symmetrically and equidistantly installed on the inner walls of both sides of the arc groove. Specifically, the racks 62 on one side of the inner wall of the arc groove and the racks 62 on the other side are arranged alternately in space. This arrangement allows the gear 61 to mesh with the racks 62 at different positions and on different sides in sequence as it moves along the arc groove, thereby driving the gear 61 to produce a reciprocating oscillating motion of forward and reverse rotation.

[0027] Multiple nozzles 32 arranged laterally on the left and right sides of the nozzle 31 are tilted and opposite each other, and multiple racks 62 are used for the reciprocating small-angle rotation of the nozzle 31. A connecting block 9 is rotatably connected to the outer side of the nozzle 31 shaft. The connecting block 9 is slidably connected in the groove of the arc-shaped groove. A first protrusion 91 is symmetrically fixedly installed in the inner mounting cavity of the connecting block 9. A second protrusion 92 is fixedly installed on the outer side of the nozzle 31 shaft. The second protrusion 92 is connected to both first protrusions 91 by springs. Under the preload of the springs, the second protrusion 92 is clamped between the two first protrusions 91, and the nozzle 31 and nozzle 32 remain in their initial deflection position. When the base plate 3 rotates, causing the nozzle 31 to move along the arc-shaped groove, the second gear 61 meshes with one of the racks 62 on one side, generating a rotational torque. At this time, the shaft of the nozzle 31 drives... When the second protrusion 92 rotates, it compresses the spring on one side and stretches the spring on the other side. The rotation of the second protrusion 92 forces the spring to deform and store elastic potential energy. When the second gear 61 disengages from the currently meshed rack 62, the external driving torque disappears. At this time, the compressed spring releases the stored elastic potential energy, pushing the second protrusion 92 to rotate in the opposite direction, causing the nozzle 31 and the first nozzle 32 to spring back to the neutral position. As the base plate 3 continues to move, the second gear 61 meshes with the other rack 62 on the other side, thereby realizing the reciprocating swing of the first nozzle 32 to deflect to the left and reset, and to deflect to the right and reset, ensuring that the extinguishing medium continuously and evenly covers the target area.

[0028] The working principle of the technical solution provided by this invention is as follows: During the use of this device, the user pushes the electric bicycle onto the placement plate 4. When the vehicle reaches the designated position, the gravity sensor senses the corresponding weight of the vehicle. At this time, the external controller controls the electric gripper 41 inside the mounting frame to automatically clamp the wheels, completing the mechanical fixation of the vehicle. The user starts the charging program by scanning the code, and the charging socket 21 on the top of the charging pile 2 starts to supply power to the electric bicycle. During the entire charging process, the three-band infrared flame sensor 22 installed on the outside of the charging pile 2 is in continuous working state. The three-band infrared flame sensor 22 performs high-precision scanning of the surrounding environment by simultaneously monitoring the radiation energy of three specific infrared wavelengths, collects infrared radiation data in real time and transmits it to the external controller for analysis. The system uses algorithms to accurately identify real flame characteristics, effectively eliminates environmental interference such as sunlight and light, and achieves fire detection with low false alarm rate and high sensitivity. When the three-band infrared flame sensor 22 detects a radiation signal that matches the characteristics of a flame, the controller immediately determines that a fire has occurred. The system immediately cuts off the power supply to the charging socket 21 to prevent electrical faults from exacerbating the fire or causing electric shock risks. At the same time as the power is cut off, the controller starts the motor, which drives the rotating shaft 11 to rotate. The rotating shaft 11 drives the base plate 3 and the placement plate 4 to rotate downwards at a certain angle, so that the burning electric bicycle enters the groove on the top of the mounting box 1 along with the placement plate 4. This action achieves physical isolation between the combustion source and the surrounding environment, effectively cutting off the path of the flame to the nearby vehicle. While the rotating shaft 11 rotates and drives the base plate 3 to rotate, the gear 51 fixed on the outside of the rotating shaft 11 rotates synchronously. The gear 51 meshes with the rack 52, thus driving the rack 52 to move upwards along the rear side wall of the sliding groove. Since the rack 52 is fixedly connected to the baffle 53 through the connecting strip, the baffle 53 is lifted upwards synchronously, forming a physical fire barrier, effectively preventing the flame from escaping and igniting the surrounding items. As the baffle 53 rises, the connecting pipe 54 and the top spray assembly 7 installed at its top rise synchronously. The controller opens the electric valve on the fire extinguisher port, and the extinguishing medium in the fire extinguisher enters the connecting pipe 54 through the hose and is guided to the second nozzle 73 of the top spray assembly 7. The second nozzle 73 is set at an angle downward, so that the extinguishing medium directly covers the hot airflow above the seat bucket, the top of the battery compartment and the flames of the burning vehicle from above, forming a top-down enveloping fire extinguishing situation. During the rise of the baffle 53, the connecting rod 81 rises synchronously. The front end of the connecting rod 81 slides against the wave-shaped contact plate 83. The contact plate 83 exerts a backward squeezing force on the connecting rod 81, forcing the connecting rod 81 to overcome the spring force and slide backward. The backward movement of the connecting rod 81 drives the push plate 84 to move. The push plate 84 drives the connecting frame 71 to slide in the connecting pipe 54, and then drives the rotating ball 72 to rotate through the connecting column, so that the second nozzle 73 deflects at an angle to increase the fire extinguishing range of the second nozzle 73. When the electric gripper 41 fixes electric bicycles of different weights, the gravity sensor monitors the weight of different vehicles. At this time, the controller will instruct the electric push rod to push the contact plate 83 to move backward by different distances to change the initial contact position between the contact plate 83 and the connecting rod 81. When the gravity sensor detects that the vehicle is heavier, the electric push rod pushes the contact plate 83 to move backward a greater distance. At this time, the contact stroke between the connecting rod 81 and the contact plate 83 increases, and the connecting rod 81 moves backward a greater distance, thereby causing the nozzle 2 73 to deflect at a larger angle, thereby obtaining a wider spray coverage range to meet the needs of heavy vehicles with larger volume fire sources. Meanwhile, as the base plate 3 rotates, gear 61 moves with the shaft of nozzle 31 and intermittently meshes with racks 62 fixed on the inner walls of the arc-shaped groove. Since racks 62 are arranged alternately in space, gear 61 meshes with racks 62 at different positions in sequence during its movement. When gear 61 meshes with one of the racks 62 on one side, generating a rotational torque, the shaft of nozzle 31 drives protrusion 92 to rotate, compressing the spring on one side and stretching the spring on the other. The rotation of protrusion 92 forces the spring to deform, storing elasticity. When gear 2 61 disengages from the currently meshing rack 2 62, the external driving torque disappears. At this time, the compressed spring releases its stored elastic potential energy, pushing the convex block 2 92 to rotate in the opposite direction, causing the nozzle 31 and nozzle 1 32 to spring back to the neutral position. As the base plate 3 continues to move, gear 2 61 meshes with another rack 2 62 on the other side, thereby realizing the reciprocating swing of nozzle 1 32 deflecting to the left and resetting, deflecting to the right and resetting, so that the extinguishing medium forms a fan-shaped coverage area, covering the frame at the bottom of the electric bicycle, the lower part of the battery compartment and other concealed areas, improving the extinguishing efficiency.
