Description

Technical field

[0001] The present invention belongs to the technical field of fireproof and explosion-proof garages, and in particular relates to a fireproof and explosion-proof garage for electric bicycles and a use method thereof. [Background Technology]

[0002] Fire extinguishers are generally ineffective in extinguishing spontaneous combustion of electric bicycle power batteries. The only option is to call the police and have professional firefighters apply large amounts of water to cool the vehicle until it burns out. Currently, the main approach is to centrally park electric bicycles and regulate their management to reduce the risk of spontaneous combustion and explosion causing fires in buildings or surrounding objects, which would otherwise cause further damage. However, spontaneous combustion and explosion of power batteries can occur very quickly and can ignite surrounding electric bicycles within tens of seconds, often igniting an entire bicycle shed, causing significant damage. Wireless charging technology has also been proposed to address the problem of spontaneous combustion and explosion caused by spontaneous combustion of the charging cable during charging. However, this technology does not address the problem of spontaneous combustion and explosion within the power battery, and it also has low charging efficiency and slow charging. Another approach is to develop safer solid-state batteries, which could fundamentally address the problem, but this technology is costly and has yet to gain widespread market adoption. Given the increasing number of electric bicycle spontaneous combustion and explosion incidents, existing market technologies are ineffective. [Summary of the invention]

[0019] Furthermore, a plurality of rubber pads are provided at the bottom of the water tank.

[0020] Furthermore, a heat insulating pad is provided on the side of the box.

[0021] Furthermore, a communication interface is provided at the lower portion of the water tank, and the communication interface is used to communicate with the water tank of an adjacent parking garage.

[0038] The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0039] The present invention provides a fireproof and explosion-proof parking garage for electric bicycles, such as Figure 1-3 As shown, it includes a box body 1, a water tank 3 and an electric pump 4. The box body 1 includes an outer box body 1 and an inner box body 1 mounted therein. The outer box body 1 and the inner box body 1 are both provided with a door 2 on the same side. The outer box body 1 is made of high-strength material and has a certain explosion-proof ability. The inner box body 1 is an insulating layer. The insulating layer has heat insulation and ablation resistance. It can slow down the rapid thermal shock of the high temperature caused by spontaneous combustion of the box body 1 on the outer box body 1, causing the strength of the outer box body 1 to fail, and prolong the fire and explosion control ability of the box body 1, so as to prevent the garage structure from failing due to long-term high temperature and the fire from getting out of control, causing a larger fire. The outer door is made of high-strength material and the inner door is an insulating layer.

[0040] The water tank 3 is mounted on top of the housing 1 and is a sealed housing 1 structure made of lightweight materials. It can store water for a long time. A water inlet 12 is provided on the water tank 3, and a gap is left between the water tank 3 and the housing 1.

[0041] like Figure 4 As shown, the electric pump 4 is located outside the water tank 3 and includes a first inlet and a second inlet that are interconnected, as well as a second inlet and a second outlet that are interconnected. The first inlet is connected to the water tank 3 via a water inlet pipe, and the first outlet is connected to a water outlet pipe 6 that extends to a position near the top of the tank body 1. The end of the water outlet pipe 6 is connected to a nozzle 5 with a downward opening. This nozzle can convert the high-pressure water from the water outlet pipe 6 into water mist and spray it into the tank body 1, achieving efficient cooling or fire extinguishing inside the tank body 1. The second inlet is connected to the outside world via an air inlet pipe, and the second outlet is connected to an air outlet pipe 7 that extends to a position near the bottom of the tank body 1.

[0042] An exhaust hole is provided on the side of the box body 1, on which a nozzle 8 is coaxially mounted. Figure 6 As shown, a dust cover 83 is provided at the outer end of the nozzle 8. The dust cover 83 is a nut with a grid in the middle, which is threadedly connected to the outlet end of the nozzle 8.

[0043] A charging cable 9 is inserted into the housing 1 through the nozzle 8 and connected to a plug-in board. This can be connected to the charging cable 9 of an electric bicycle to charge the electric bicycle. The charging cable 9 enters through the hole in the center of the dust cover 83. The gap in the grille is much larger than the diameter of the charging cable 9, ensuring that the housing 1 is connected to the atmosphere.

[0044] The housing 1 is used to store electric bicycles, and the water tank 3 is used to store water. An electric pump 4 draws water from the water tank 3 and discharges it through a water outlet pipe 6 to extinguish fires and cool the air. The electric pump 4 also draws in air from the outside and discharges it through an air outlet pipe 7 to cool the air. At normal temperatures, the interior of the housing communicates with the outside world through the vents, ensuring air circulation and pressure balance. When the temperature inside the housing becomes too high, the electric pump activates, increasing the pressure inside the housing. The pressure differential between the inside and outside of the housing causes the hot air inside the housing to be discharged through the vents.

[0045] In some embodiments, an intelligent management terminal is further included, which has:

[0046] A charging management module is used to monitor the charging process and automatically cut off the charge when abnormal charging occurs or the battery is fully charged;

[0047] A temperature control module, used to monitor the presence of smoke and the temperature status in the box 1;

[0048] An alarm module is used to send an alarm signal to the smart community management system to seek professional assistance when smoke or high temperature occurs;

[0049] An exhaust control module is used to start the electric pump 4 to draw outside air into the box 1 through the outlet pipe 7 when the temperature in the box 1 exceeds a set threshold value, which can be set to 50°C, and to discharge the high-temperature gas in the box 1 through the nozzle 8;

[0050] A spray control module is used to start the electric pump 4 to suck water from the water tank 3 and discharge it through the water outlet pipe 6 when smoke appears in the box 1, and spray water mist into the box 1 to cool it down until the temperature in the box 1 drops to a safe value and the smoke dissipates, and then stop working.

[0051] In some embodiments, a pressure relief hole 14 is provided on the side of the box 1, and a pressure relief plate is provided on the pressure relief hole 14. When the pressure inside the box 1 exceeds a certain value, the pressure relief plate automatically cuts open under the pressure of the box 1, quickly reducing the pressure inside the box 1 to prevent the box 1 from exploding and causing the fire to get out of control.

[0052] A plurality of low-pressure relief ports 17 are provided at the bottom of the box 1. When there is too much high-temperature gas in the box 1 and the exhaust capacity is insufficient, the low-pressure relief ports 17 will open under the action of the pressure and high temperature of the box 1 to quickly exhaust gas and reduce the pressure and temperature in the box 1 to prevent the pressure relief ports from opening or the discharge of high-temperature gas from causing harm to external personnel or objects.

[0053] When the pressure relief plate 14 is opened, the pressure in the box increases sharply, and the low-pressure relief port 17 is opened when the pressure in the box is high. Therefore, from the perspective of pressure gradient, the low-pressure relief port 17 is opened before the pressure relief plate 14 is opened.

[0054] In some embodiments, as Figure 5 As shown, the nozzle 8 includes a hollow cylinder 81 and a throat liner 82 coaxial with and connected to the hollow cylinder 81. The hollow cylinder 81 is made of metal, and the throat liner 82 is made of fiberglass, which can resist the erosion of high-temperature gas for a long time and prevent the nozzle shell from being quickly heated and failing.

[0055] In some embodiments, a plurality of rubber pads 11 are provided at the bottom of the water tank 3 to reduce the risk of high temperature from the tank body 1 being transferred into the water tank 3 and damaging the structure of the water tank 3 .

[0056] In some embodiments, a heat insulating pad 15 is provided on the side of the box body 1 to prevent the garage units from contacting each other when they are combined, reduce the transfer of high temperature between them, and prevent the spontaneous combustion and explosion of one garage unit from causing a fire in the adjacent garage unit.

[0057] In some embodiments, as Figure 7 As shown, a connection port 18 is provided at the bottom of the water tank 3 for connecting to the water tank 3 of an adjacent parking garage. This allows for connection of the water tanks 31 when multiple fireproof and explosion-proof parking garages for electric bicycles are combined. The number and location of fireproof and explosion-proof parking garages for electric bicycles can be flexibly combined to accommodate various parking spaces, facilitating standardized parking and management.

[0058] The side of the box body 1 is provided with a heat insulation pad 15 to prevent the garage units from contacting each other when they are assembled, reduce the high temperature transfer between them, and prevent the spontaneous combustion and explosion of one garage unit from causing a fire in the adjacent garage unit.

[0059] A water tank 3 cover is provided on the water inlet 12 to prevent foreign matter from entering the water tank 31. A control screen 10 is provided on the water tank 3. A dust cover 13 is provided at the position where the electric pump 4 is provided on the water tank 3 to provide dust protection for the electric pump 4 system 3.

[0060] The present invention provides a method for using a fireproof and explosion-proof parking garage for electric bicycles, based on a fireproof and explosion-proof parking garage for electric bicycles, including the following contents:

[0061] Park the electric bicycle in a fireproof and explosion-proof garage and close the door to keep it warm and protect it from wind and rain;

[0062] When charging is needed, connect the electric bicycle to the plug board to charge. The charging process is managed by the charging management module. If the charging is abnormal or the battery is fully charged, the power will be automatically cut off.

[0063] When the temperature control module detects that the temperature inside the box 1 is too high, the electric pump 4 starts working, extracting air from the atmospheric environment and sending it into the box 1, and exhausting the high-temperature gas in the box 1 through the nozzle 8. The high-temperature gas in the box 1 is discharged to cool it down. When the temperature drops to the set temperature, the electric pump 4 stops working.

[0064] When the temperature control module detects smoke, which may indicate spontaneous combustion of the electric bicycle, the spray control module activates the electric pump 4 to draw water from the water tank 3 and discharge it through the water outlet pipe 6, and continuously sprays water mist into the box body 1 to cool it down until the temperature inside the box body 1 drops to a safe value and the smoke dissipates, and then stops working;

[0065] When the temperature control module detects smoke or high temperature signals, it transmits the monitoring information to the alarm module for alarm, and at the same time sends an alarm signal to the smart community management system to seek professional assistance.

[0066] In some embodiments, if the electric bicycle explodes, the low-pressure relief port 17 is opened to quickly exhaust the air from the box 1 to reduce the pressure and temperature, so as to prevent the garage from being damaged and the fire from getting out of control.

[0067] The present invention, through the coordinated work of multiple intelligent control systems, can realize the timely detection of spontaneous combustion and explosion, automatic alarm, timely assistance to social professional fire-fighting resources, and timely handling of fires to prevent the fire from getting out of control and spreading, causing greater losses. The present invention has the ability to autonomously control the spread of spontaneous combustion and explosion, avoiding sudden spontaneous combustion and explosion from harming the surrounding people; at the same time, it can continuously control the spread of fire for a long time, leaving more time for the arrival of social professional fire-fighting resources. The present invention has a charging function, and can also automatically cut off the power when charging is abnormal or fully charged, to prevent the power battery from burning or exploding due to abnormal charging or overcharging. The present invention has the ability to extinguish circuit fires and small flames, which can minimize the losses caused by such spontaneous combustion. The present invention has an insulating effect on electric bicycles in the garage, which can prevent the temperature of the bottom of the pot from damaging the electric bicycle, especially the power battery, in a low-temperature environment, thereby extending the life of the electric bicycle and the power battery.
