Description

[Technical Field]

[0001] This utility model belongs to the field of fireproof and explosion-proof garage technology, specifically relating to a fireproof and explosion-proof parking garage for electric bicycles. [Background Technology]

[0002] Fire extinguishers are generally ineffective in extinguishing spontaneous combustion of electric bicycle batteries. The only solution is to call the fire department and have professional firefighters use large amounts of water to cool the fire until it burns out completely. Currently, the main approach is to manage electric bicycles in designated areas to reduce the risk of fires spreading to buildings or surrounding property, causing even greater damage. However, spontaneous combustion and explosion of electric bicycle batteries can occur very quickly, igniting surrounding bicycles within seconds and often resulting in a fire covering the entire bicycle shed, causing significant losses. There are also proposals to use wireless charging technology to address spontaneous combustion and explosion caused by charging cables, but this technology cannot solve the problem of internal battery combustion and explosion, and it has low charging efficiency and is slow. Furthermore, developing safer solid-state batteries could fundamentally solve the problem, but this technology is expensive and not yet widely available. With over 300 million electric bicycles in my country, replacement in the short term is difficult, and the risk of spontaneous combustion and explosion remains. The annual increase in electric bicycle spontaneous combustion and explosion incidents indicates that existing technologies are not effective. [Utility Model Content]

[0003] The purpose of this invention is to provide a fireproof and explosion-proof parking garage for electric bicycles, so as to solve the problem that existing technologies cannot quickly and effectively solve the problem of spontaneous combustion and explosion during the charging process of electric bicycles.

[0013] A temperature control module is used to monitor whether smoke appears inside the chamber and the temperature status;

[0014] An alarm module is used to issue an alarm signal when smoke or high temperature is present;

[0015] An exhaust control module is used to start an electric pump to draw in outside air and deliver it into the chamber through an exhaust pipe when the temperature inside the chamber exceeds a set threshold, and then discharge the high-temperature gas inside the chamber through a nozzle.

Detailed Implementation Methods

[0031] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments.

[0032] This utility model provides a fireproof and explosion-proof parking garage for electric bicycles, such as... Figure 1-3 As shown, the system includes a housing 1, a water tank 3, and an electric pump 4. The housing 1 comprises an outer housing 1 and an inner housing 1 housed within it. Both the outer and inner housings 1 have doors 2 on the same side. The outer housing 1 is made of high-strength material and has a certain degree of explosion-proof capability. The inner housing 1 is an insulation layer, which has heat insulation and ablation resistance capabilities. This insulation layer can mitigate the rapid thermal shock from the high temperature of spontaneous combustion of the housing 1 to the outer housing 1, preventing the outer housing 1 from failing and extending the fire and explosion-proof control capability of the housing 1. This prevents the garage structure from failing due to prolonged high temperatures, thus avoiding a larger fire caused by uncontrolled fire. The outer door is made of high-strength material, and the inner door is an insulation layer.

[0033] Water tank 3 is installed on top of tank 1, and it is a sealed tank structure made of lightweight materials. It can store water for a long time. Water tank 3 is provided with water inlet 12, and there is a gap between water tank 3 and tank 1.

[0034] like Figure 4 As shown, the electric pump 4 is located outside the water tank 3. It 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 an inlet pipe, and the first outlet is connected to an outlet pipe 6. The outlet pipe 6 extends into the tank 1 near the top, and its end is connected to a downward-facing nozzle 5, which can spray the high-pressure water from the outlet pipe 6 into the tank 1 as a water mist for efficient cooling or fire extinguishing. The second inlet is connected to the outside via an air inlet pipe, and the second outlet is connected to an air outlet pipe 7. The air outlet pipe 7 extends into the tank 1 near the bottom.

[0035] An exhaust port is located on the side of the housing 1, and a nozzle 8 is coaxially mounted on it, such as... Figure 6 As shown, a dust cover 83 is provided at the outer port of the nozzle 8. The dust cover 83 is a nut with a grid in the middle, which is threaded to the outlet end of the nozzle 8.

[0036] A charging cable 9 is inserted into the housing 1 via a nozzle 8 and connected to a power strip. It can be connected to the charging cable 9 of an electric bicycle to enable charging of the electric bicycle. The charging cable 9 enters through the hole in the middle of the dust cover 83. The gap area of ​​the grille is much larger than the diameter of the charging cable 9, ensuring that the housing 1 is in contact with the atmospheric environment.

[0037] The enclosure 1 is used to park electric bicycles, and the water tank 3 is used for water storage. An electric pump 4 draws water from the water tank 3 and discharges it through the outlet pipe 6 for fire extinguishing and cooling. The electric pump 4 also draws in outside air and discharges it through the air outlet pipe 7 for cooling. At normal temperature, the enclosure is connected to the outside environment through an exhaust vent, allowing for air circulation and pressure balance. When the temperature inside the enclosure becomes too high, the electric pump operates, increasing the pressure inside the enclosure. This pressure difference forces the hot air inside the enclosure to be discharged through the exhaust vent.

[0038] In some embodiments, a smart management terminal is further included, which has:

[0039] A charging management module is used to monitor the charging process and automatically disconnect when a charging abnormality occurs or when the battery is fully charged.

[0040] A temperature control module is used to monitor whether smoke appears inside the chamber 1 and the temperature status;

[0041] An alarm module is used to send an alarm signal to the smart community management system in the event of smoke or high temperature to seek professional assistance.

[0042] An exhaust control module is used to start the electric pump 4 to draw in outside air and deliver it into the chamber 1 through the exhaust pipe 7 when the temperature inside the chamber 1 exceeds a set threshold, which can be set to 50°C. The high-temperature gas inside the chamber 1 is then discharged through the nozzle 8.

[0043] A spray control module is used to start the electric pump 4 to draw water from the water tank 3 and discharge it through the water outlet pipe 6 when smoke appears inside the chamber 1, and spray water mist into the chamber 1 to cool it down until the temperature inside the chamber 1 drops to a safe value and the smoke dissipates, after which the operation stops.

[0044] In some embodiments, a pressure relief hole 14 is provided on the side of the housing 1, and a pressure relief plate is provided on the pressure relief hole 14. When the pressure inside the housing 1 exceeds a certain value, the pressure relief plate is automatically cut open under the pressure of the housing 1 to quickly reduce the pressure inside the housing 1, so as to prevent the housing 1 from bursting and causing the fire to get out of control.

[0045] The bottom of the housing 1 is equipped with multiple low-pressure relief ports 17. When there is too much high-temperature gas inside the housing 1 and the exhaust capacity is insufficient, the low-pressure relief ports 17 will open under the pressure and high temperature of the housing 1 to quickly exhaust the gas and reduce the pressure and temperature inside the housing 1, so as to prevent the opening of the relief port or the exhaust of high-temperature gas from causing harm to external personnel or objects.

[0046] When the pressure relief plate 14 is opened, the pressure inside the chamber increases sharply. The low-pressure relief port 17 is opened when the pressure inside the chamber is high. Therefore, from the perspective of pressure gradient, the low-pressure relief port 17 was already open before the pressure relief plate 14 was opened.

[0047] In some embodiments, such as Figure 5 As shown, the nozzle 8 includes a hollow cylinder 81 and a throat liner 82 that is coaxial with and communicates with 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 gases for a long time and prevent the nozzle housing from failing due to rapid heat.

[0048] In some embodiments, a plurality of rubber pads 11 are provided at the bottom of the water tank 3 to reduce the transmission of high temperature from the tank body 1 to the water tank 3 and prevent damage to the structure of the water tank 3.

[0049] In some embodiments, the side of the housing 1 is provided with a heat insulation pad 15 to prevent the individual garage units from contacting each other when they are assembled, thereby reducing the transfer of high temperature between them and preventing a fire in the adjacent garage unit if one garage unit spontaneously combusts or explodes.

[0050] In some embodiments, such as Figure 7 As shown, the lower part of the water tank 3 is provided with a connecting interface 18, which is used to connect with the water tank 3 of an adjacent parking garage. This allows for the connection of multiple fireproof and explosion-proof parking garages for electric bicycles when combined. The number and location of these parking garages can be flexibly combined to adapt to various parking space requirements, facilitating standardized parking and management.

[0051] The side of the enclosure 1 is equipped with a heat insulation pad 15 to prevent the individual garage units from coming into contact with each other when they are assembled, thereby reducing the transfer of high temperature between them and preventing a fire in the adjacent garage unit if one garage unit spontaneously combusts or explodes.

[0052] A water tank cover 3 is provided on the water inlet 12 to prevent foreign objects from entering the water tank 31. A control panel 10 is provided on the water tank 3. A dust cover 13 is provided on the water tank 3 at the location of the electric pump 4 to protect the electric pump 4 system 3 from dust.

[0053] This utility model discloses a method for using a fireproof and explosion-proof parking garage for electric bicycles, including the following:

[0054] Parking electric bicycles in fireproof and explosion-proof parking garages and closing the doors can keep them warm and protect them from wind and rain.

[0055] When charging is needed, connect the electric bicycle to the power strip. The charging process is managed by the charging management module, which will automatically cut off the power if there is an abnormality or when the battery is fully charged.

[0056] If the temperature control module detects that the temperature inside the chamber 1 is too high, the electric pump 4 will start working, drawing air from the atmosphere and sending it into the chamber 1, and expelling the high-temperature gas inside the chamber 1 through the nozzle 8. The temperature will be lowered by expelling the high-temperature gas inside the chamber 1 until the temperature drops to the set temperature, at which point the electric pump 4 will stop working.

[0057] If the temperature control module detects smoke, it may be due to spontaneous combustion of the electric bicycle. In this case, the sprinkler control module starts the electric pump 4 to draw water from the water tank 3 and discharge it through the water outlet pipe 6. It then continuously sprays water mist into the box 1 to cool it down until the temperature inside the box 1 drops to a safe value and the smoke dissipates, at which point it stops working.

[0058] When the temperature control module detects smoke or high temperature signals, it transmits the monitoring information to the alarm module to trigger an alarm, and at the same time sends an alarm signal to the smart community management system to seek professional assistance.

[0059] In some embodiments, if the electric bicycle explodes, the low-pressure relief port 17 is opened to quickly vent air from the housing 1 to reduce pressure and temperature, so as to prevent damage to the garage and loss of fire control.

[0060] This invention utilizes a multi-functional intelligent control system to coordinate and promptly detect spontaneous combustion and explosion, automatically alarm, and call for professional firefighting resources to control the fire and prevent its uncontrolled spread and greater losses. It possesses the ability to autonomously control spontaneous combustion and explosion to prevent injury to surrounding people; it can also sustainably control the fire for an extended period, allowing sufficient time for professional firefighting resources to arrive. This invention features a charging function and automatically cuts off power in case of abnormal charging or when fully charged to prevent battery combustion or explosion caused by overcharging. It has the ability to extinguish electrical fires and small flames, minimizing losses from spontaneous combustion. This invention also provides insulation for electric bicycles in garages, preventing damage to the bicycle, especially the battery, caused by the high temperature of the pot bottom in low-temperature environments, thus extending the lifespan of both the electric bicycle and the battery.
