Description

Technical Field

[0001] The invention relates to the technical field of fire safety, in particular to a fire suppression device for an electric bicycle shed. Background Art

[0002] With the increasing popularity of electric bicycles, fire safety issues are becoming increasingly prominent in electric bicycle sheds, which serve as centralized charging and parking locations. Lithium batteries in electric bicycles are prone to thermal runaway due to overcharging, short circuiting, and aging, which can lead to fires. Once a fire breaks out in an electric bicycle shed, due to the dense concentration of vehicles and the relatively enclosed space within, the fire spreads rapidly, causing serious property damage and casualties.

[0003] Existing electric bicycle sheds often use sprinkler systems to extinguish fires through the continuous spraying of water-based fire extinguishing agents. However, these sprinkler systems have fixed nozzles, which limit their coverage area. Furthermore, the flexible parking positions of electric bicycles in sheds result in inefficient sprinkler systems and inability to extinguish fires in a timely manner. Summary of the Invention

[0008] In some embodiments, the adapter plate includes a plate body, the plate body is fixed to the bottom of the ceiling frame, and a plurality of the control valves are evenly spaced on the plate body; A plurality of adapter grooves are arranged on the plate body at equal intervals, and the suppression component is provided at the bottom of the adapter groove.

[0009] In some embodiments, the suppression assembly includes at least three water mist nozzles, which are arranged in a ring shape at the bottom of the suppression assembly and are connected to the delivery branch pipe. Two adjacent suppression assemblies are centrally symmetrically arranged.

[0010] In some embodiments, the suppression assembly further comprises a rotating disk, the rotating disk being disposed between the three water mist nozzles and the adapter plate, the spray direction of the water mist nozzle being oblique to the central axis of the rotating disk; A rotating ring, the rotating ring being coaxially arranged on the top of the rotating disk; A limiting ring is coaxially arranged on the top of the rotating ring and is rotatable and sealed in the adapter groove.

[0011] In some embodiments, a plurality of barrier components are further included, and the plurality of barrier components are arranged at equal intervals at the bottom of the charging shed to divide the charging shed into a plurality of charging areas.

[0012] In some embodiments, the barrier assembly includes a fireproof board, and the fireproof board is provided at the bottom of the charging shed; Two plug-in slots, the two plug-in slots are arranged on both sides of the fireproof board; An auxiliary inhibitor is plugged into and matched with the plug-in slot.

[0013] In some embodiments, the auxiliary inhibitor includes an inhibitor block, and the inhibitor block is plug-fitted into the plug-in slot; an explosion chamber filled with explosives; an explosion channel, the explosion channel being connected to the explosion chamber and containing a fire extinguishing agent; A sealing plug, the sealing plug is blocked on a side of the explosion channel away from the explosion chamber; The heat-conducting metal is embedded in the suppression block, and one end of the heat-conducting metal extends to the explosion cavity, and the other end protrudes from the suppression block away from the surface of one side of the plug-in slot.

[0014] A method for suppressing fire in an electric bicycle shed comprises the following steps: The fire detector monitors the environmental parameters in the charging shed in real time. When the temperature, smoke concentration and other parameters detected exceed the preset threshold, it is determined that a fire has occurred and a fire signal is transmitted to the control unit; After receiving the fire signal, the control unit immediately activates the sound and light alarm device to sound an alarm and remind people to evacuate; The control unit simultaneously controls the delivery pump to start, and the delivery pump extracts the water-based fire extinguishing agent from the storage tank and delivers it to each of the delivery branch pipes through the delivery main pipe; The control unit controls the control valve above the fire position to open, and the water-based fire extinguishing agent enters the adapter groove on the adapter plate; The water-based fire extinguishing agent enters the suppression assembly through the adapter groove and is sprayed out from the three water mist nozzles. Since the spray direction of the water mist nozzle is obliquely toward the central axis of the rotating disk, under the reaction force of the water flow, the rotating disk drives the water mist nozzle to rotate, so that the water mist is evenly sprayed in the charging shed, covering the fire area and suppressing the spread of fire.

[0015] One or more of the above technical solutions in the embodiments of the present invention have at least the following technical effects or advantages: (1) The present invention increases the coverage of the water-based fire extinguishing agent spraying by arranging water mist nozzles in a ring shape at equal intervals on the roof of the electric bicycle shed, thereby achieving effective control and extinguishing of the spread of fire, improving the fire safety level of the electric bicycle shed, and reducing the losses caused by fire. At the same time, the flow rate of the water-based fire extinguishing agent in the central area can be increased, and the water-based fire extinguishing agent sprayed by multiple water mist nozzles can divide the fire at the corresponding position into multiple fire extinguishing areas. While achieving normal fire extinguishing in the area covered by a single water mist nozzle, the speed of fire extinguishing in the overlapping area can be improved. After the fire in the overlapping area is extinguished, positive feedback is given to the fire extinguishing in the single coverage area, thereby improving the fire extinguishing speed of the entire fire.

[0016] (2) The present invention can rotate the rotating disk and the adapter plate to rotate the rotating disk when multiple water mist nozzles spray water-based fire extinguishing agents, thereby driving the water mist nozzles to rotate. The water mist sprayed by the water mist nozzles forms a fan-shaped atomization surface through the combined action of centrifugal force and pressure, and the coverage angle can reach 180°~360. At the same time, the oblique spray is combined with the rotational motion to form a spiral flow field of the water mist. The centrifugal force generated by the rotation can refine the droplet particle size, increase the specific surface area, and improve the heat exchange efficiency. In addition, the oblique angle makes the water mist have a component velocity in the horizontal direction, which can diffuse laterally along the surface of the burning object to form a "wrapped" cooling layer, effectively preventing the external oxygen from diffusing into the combustion zone and suppressing the re-ignition effect.

[0017] (3) The present invention can realize the partitioning of the electric bicycle shed through the barrier components, and at the same time, the fire extinguishing agent is sprayed in the fire area through the auxiliary suppression components to achieve fire blocking and auxiliary fire extinguishing, thereby improving the efficiency of fire suppression.

The fire detector 2 can adopt a composite sensor and can adopt multi-parameter sensor fusion technology to integrate smoke sensors, temperature sensors, combustible gas sensors, etc., which can quickly and accurately detect the occurrence of fire. The suppression cabinet 3 is located on one side of the charging shed 1, and can be installed with a storage tank 4, a delivery pump 5, and a control unit 8 for protection and centralized control. The storage tank 4 is located in the suppression cabinet 3. The storage tank 4 stores water-based fire extinguishing agent to provide a material basis for fire extinguishing. The storage tank 4 can be made of stainless steel, and the interior The entire structure is treated with corrosion protection to ensure that the long-term storage of water-based fire extinguishing agent does not leak. The delivery pump 5 is located in the suppression cabinet 3 and is connected to the storage tank 4. Under the control of the control unit 8, it can deliver the water-based fire extinguishing agent in the storage tank 4 to the suppression structure 7.

When the water-based fire extinguishing agent is insufficient, the control unit 8 controls the sound and light alarm device 6 to sound an alarm to remind the user to replenish the water-based fire extinguishing agent in time.

[0026] In some embodiments, the charging shed 1 includes a plurality of columns 11 fixed to the ground, a roof frame 12, a plurality of shed boards 13, a fixing plate 14 and a plurality of charging sockets 15. The plurality of columns 11 build a stable support structure for the charging shed 1. The roof frame 12 is fixed on the top surface of the plurality of columns 11 to form a frame of the roof. The columns 11 and the roof frame 12 can be made of hot-dip galvanized steel with good strength and corrosion resistance. A fire detector 2 and a suppression structure 7 are provided at the bottom of the roof frame 12. The former is used to monitor fire hazards in real time, and the latter is used to extinguish fires. 3 is arranged on the top of the roof frame 12 to provide protection from wind and rain. The shelf board 13 can be tilted to avoid water accumulation on the shelf board 13. The shelf board 13 can be made of fire-proof colored steel plate. The fixing plate 14 is arranged at one end of the plurality of columns 11. A plurality of charging sockets 15 are evenly spaced and arranged on the fixing plate 14. The fixing plate 14 can be made of stainless steel plate to ensure that the charging sockets 15 are firmly installed. The charging sockets 15 can provide a charging interface for the electric bicycle. The charging sockets 15 are electrically connected to the control unit 8. The control unit 8 can cut off the charging power supply in time when a fire occurs to avoid more serious dangers caused by continuous charging.

[0027] In some embodiments, the suppression structure 7 includes a delivery main pipe 71, an adapter plate 72, a plurality of delivery branch pipes 73, a suppression assembly 74 and a control valve 75. The delivery main pipe 71 is arranged on the ceiling frame 12 and is connected to the delivery pump 5. It is responsible for the initial delivery of the water-based fire extinguishing agent in the storage tank 4. The adapter plate 72 is arranged at the bottom of the ceiling frame 12. The plurality of delivery branch pipes 73 are arranged at equal intervals between the adapter plate 72 and the delivery main pipe 71 to distribute and deliver the fire extinguishing agent. The suppression assembly 74 is arranged between the delivery branch pipe 73 and the adapter plate. 72, water-based fire extinguishing agent can be sprayed onto the fire to extinguish the fire. The main delivery pipe 71 and the delivery branch pipe 73 can be made of galvanized steel pipes, and the pipe diameter is determined according to the design flow to ensure smooth delivery of the fire extinguishing agent. The control valve 75 is arranged between the delivery branch pipe 73 and the adapter plate 72 and is electrically connected to the control unit 8. The control valve 75 can be a solenoid valve and can be wirelessly connected to the control unit 8. The control unit 8 can accurately control the on and off of each delivery branch pipe 73 through the control valve 75, thereby achieving targeted fire extinguishing in different areas.

[0028] In some embodiments, the adapter plate 72 includes a plate body 721 and multiple adapter grooves 722. The plate body 721 is fixed to the bottom of the ceiling frame 12 and can be welded or fixed by bolts. Multiple control valves 75 and adapter grooves 722 are evenly spaced on the plate body 721. A suppression assembly 74 is installed at the bottom of each adapter groove 722. This layout enables the fire extinguishing agent to be efficiently transmitted to each suppression assembly 74.

[0029] In some embodiments, the suppression component 74 includes at least three water mist nozzles 741. The water mist nozzles 741 can be made of brass and chrome-plated on the surface to prevent corrosion and clogging. The three water mist nozzles 741 are arranged in a ring shape at the bottom of the suppression component 74 and are connected to the delivery branch pipe 73. The two adjacent suppression components 74 are arranged symmetrically in the center to increase the coverage area of ​​the fire-extinguishing water mist. At the same time, the three water mist nozzles 741 can increase the water mist flow in the central area, thereby improving the fire extinguishing efficiency in the overlapping area.

[0030] The aqueous fire extinguishing agent sprayed by the three water mist nozzles 741 can divide the fire at the corresponding position into multiple fire extinguishing areas. While achieving normal fire extinguishing in the area covered by a single water mist nozzle 741, it can improve the speed of fire extinguishing in the overlapping area. After the fire in the overlapping area is extinguished, it can provide positive feedback to the fire extinguishing in the single coverage area, thereby improving the fire extinguishing speed of the entire fire.

[0031] In some embodiments, the suppression assembly 74 further includes a rotating disk 744, a rotating ring 742, and a retaining ring 743. The rotating disk 744 is positioned between the three water mist nozzles 741 and the adapter plate 72. The spray direction of the water mist nozzles 741 is oblique to the central axis of the rotating disk 744. The rotating ring 742 is coaxially disposed on the top of the rotating disk 744. The retaining ring 743 is coaxially disposed on the top of the rotating ring 742 and is rotatable and sealed within the adapter groove 722, which can be sealed by a sealing ring. The rotating disk 744, rotating ring 742, and retaining ring 743 can all be made of stainless steel, which has excellent wear resistance and lubricity. When the water mist nozzles 741 spray water, the reverse force of the water mist impacts the rotating disk 744, driving the rotating disk 744, rotating ring 742, and retaining ring 743 to rotate. The water mist forms a fan-shaped atomization surface through the combined action of centrifugal force and pressure, with a coverage angle of 180° to 360°. The oblique spray combined with the rotational motion causes the water mist to form a spiral flow field. The centrifugal force generated by rotation refines the droplet size to 20-150μm, increasing the specific surface area and improving heat exchange efficiency. The oblique angle imparts a horizontal velocity component to the mist, allowing it to diffuse laterally along the surface of the burning object, forming a "wrapped" cooling layer that effectively blocks the diffusion of external oxygen into the combustion zone and inhibits re-ignition. It also prolongs the mist droplet's trajectory in the air, increasing its residence time and broadening the mist curtain's coverage area.

[0032] In some embodiments, in order to effectively prevent the spread of fire, multiple barrier components 9 are also included. Multiple barrier components 9 are arranged at equal intervals at the bottom of the charging shed 1, dividing the charging shed 1 into multiple charging areas, playing the role of space separation and safety protection.

[0033] In some embodiments, the barrier assembly 9 includes a fireproof board 91, two plug-in slots 92 and an auxiliary suppression component 93. The fireproof board 91 is arranged at the bottom of the charging shed 1 and is vertically connected to the fixed plate 14. It can realize fire separation and can prevent the spread of fire when a fire occurs. The fireproof board 91 can adopt an inorganic fireproof board, which can effectively prevent the spread of fire. The two plug-in slots 92 are arranged on both sides of the fireproof board 91, and the auxiliary suppression component 93 is plugged into the plug-in slot 92.

[0034] In some embodiments, the auxiliary suppression member 93 includes a suppression block 931, an explosion cavity 932, an explosion channel 933, a sealing plug 934 and a heat-conducting metal 935. The suppression block 931 is plugged into the plug slot 92 to achieve the installation of the auxiliary suppression member 93. The explosion cavity 932 is filled with explosives, which can be lead azide, which can generate explosive impact force when heated when a fire occurs. The explosion channel 933 is connected to the explosion cavity 932, and a fire extinguishing agent is provided in the explosion channel 933, which can be a dry powder fire extinguishing agent. The impact force generated by the explosion can spray the fire extinguishing agent to extinguish the fire. The explosion power of the auxiliary suppression member 93 has been precisely designed and is effective. While spraying the fire extinguishing agent, it does not cause harm to surrounding personnel or equipment. A sealing plug 934 blocks the side of the explosion channel 933 away from the explosion chamber 932 to prevent the fire extinguishing agent from leaking or becoming humid. The sealing plug 934 can be made of a high-temperature-resistant, high-strength ceramic material. A thermally conductive metal 935 is embedded within the suppression block 931, with one end extending into the explosion chamber 932 and the other end protruding from the surface of the suppression block 931 away from the socket 92. When a fire occurs, the thermally conductive metal 935 can transfer heat to the explosion chamber 932, triggering the explosion of the explosive. The thermally conductive metal 935 can be made of pure copper, which has a high thermal conductivity and ensures sensitive heat conduction. When a fire occurs in this area, the high temperature causes the thermally conductive metal 935 to transfer heat to the explosion chamber 932, triggering the explosion of the explosive, breaking through the sealing plug 934 and releasing the fire extinguishing agent within the explosion channel 933, thereby quickly suppressing the fire and further preventing the spread of the fire. A grooved metal strip may be provided between the two fireproof panels 91. The middle portion of the metal strip is embedded in the ground of the charging shed 1, and both ends are fixed on the two fireproof panels 91 and in contact with the heat-conducting metal 935. This can promptly transfer the heat from the fire between the two fireproof panels 91, thereby achieving timely fire extinguishing.

[0035] A method for suppressing fire in an electric bicycle shed comprises the following steps: Fire detection: Fire detector 2 monitors the smoke concentration, temperature, combustible gas concentration and other parameters in the charging shed 1 in real time and transmits the data to control unit 8. When the monitoring data exceeds the preset threshold, fire detector 2 determines that a fire has occurred and sends a fire signal to control unit 8.

[0036] Alarm start: After receiving the fire signal, the control unit 8 immediately triggers the sound and light alarm device 6 to emit a high-decibel sound and high-brightness flash to remind people to evacuate. At the same time, it can send fire alarm information to the management personnel's mobile phone terminal through the wireless network to notify relevant personnel to deal with it in time, and control the charging socket 15 to cut off the power to prevent the fire from being aggravated due to electrical reasons.

[0037] Partition positioning: The control unit 8 determines the specific area where the fire occurs based on the installation location and monitoring data of the fire detector 2.

[0038] Start fire extinguishing: The control unit 8 controls the control valve 75 of the corresponding area to open according to the area where the fire occurs, starts the delivery pump 5, and delivers the water-based fire extinguishing agent in the storage tank 4 to the suppression component 74 in the area through the delivery main pipe 71 and the delivery branch pipe 73.

[0039] The water-based fire extinguishing agent enters the suppression assembly 74 through the adapter slot 722 and is sprayed out from the three water mist nozzles 741. Because the spray direction of the water mist nozzle 741 is oblique to the central axis of the rotating disk 744, the rotating disk 744 drives the water mist nozzle 741 to rotate under the reaction force of the water flow. The rotating water mist nozzle 741 sprays the fire extinguishing agent evenly in a 360-degree ring shape on the fire area. The water mist absorbs a large amount of heat during evaporation, reducing the temperature in the fire area, while isolating oxygen and suppressing the spread of fire.

[0040] Auxiliary fire extinguishing: The fireproof plate 91 in the barrier assembly 9 can prevent the spread of fire between different charging areas. When the fire is large, the heat generated by the flames and high temperature is transferred to the heat-conducting metal 935 of the barrier assembly 9. The heat is transferred to the explosion cavity 932 through the heat-conducting metal 935. When the temperature of the heat-conducting metal 935 reaches the trigger temperature of the explosive, such as 180°C, the explosive in the explosion cavity 932 quickly explodes. The impact force generated by the explosion will break open the sealing plug 934, and the fire extinguishing agent in the explosion channel 933 will be instantly ejected, forming a fire extinguishing agent barrier around the fire area, preventing the fire from spreading to adjacent charging areas. The ejected fire extinguishing agent helps suppress the fire and further reduce the fire intensity.

[0041] Continuous Monitoring and Control: During the fire extinguishing process, fire detectors 2 continuously monitor the fire area and feed this data back to control unit 8. Based on this data, control unit 8 adjusts the flow rate of delivery pump 5 and the opening of control valve 75 to ensure effective fire extinguishing. Once the fire is extinguished, control unit 8 stops delivery pump 5, closes control valve 75, and deactivates the audible and visual alarms.

[0042] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit the same. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein.
