[0034] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0035] In order to make the above-mentioned objects, features and advantages of the present application more obvious and easy to understand, the present application is further described in detail below with reference to the accompanying drawings and specific implementation methods.

[0036] In an exemplary embodiment, Figure 1 and Figure 2 As shown, an electric bicycle charging cabinet is provided, and the electric bicycle charging cabinet includes: an explosion-proof module, a sensing and alarm module 3, a fire extinguishing module and a control module;

[0037] The explosion-proof module includes: a charging cabinet cavity 4 and an explosion-proof upper cover door 2; the explosion-proof upper cover door 2 is arranged on the top of the charging cabinet cavity 4; the charging cabinet cavity 4 is used to charge the battery of the electric bicycle placed in the cavity;

[0038] The sensing and alarm module 3 is arranged on the lower surface of the explosion-proof upper cover door 2 and is connected to the control module; the sensing and alarm module 3 is used to alarm when the temperature data and smoke data in the charging cabinet cavity 4 exceed the set threshold;

[0039] The fire extinguishing module is connected to the control module; the control module is used to control the charging cabinet cavity 4 to stop charging the battery of the electric bicycle when the temperature and smoke data in the charging cabinet cavity 4 exceed the set threshold, and control the fire extinguishing module to extinguish the battery. That is, when a fire occurs, the control module immediately cuts off the power supply to ensure the safety of electricity use, and at the same time opens the solenoid valve 5 to allow water to flow into the charging cabinet cavity 4 to extinguish the battery.

[0040] In order to facilitate the use of the electric bicycle charging cabinet, the explosion-proof module further includes: an explosion-proof upper cover door 2 handle; the explosion-proof upper cover door handle 1 is arranged on the upper surface of the explosion-proof upper cover door 2.

[0041] The entire explosion-proof module is constructed with special materials that are resistant to high temperatures, flame retardant and corrosion-resistant. It has good structural strength and protective performance. It can effectively withstand internal pressure and can also resist external impacts, fire attacks and other unexpected situations.

[0042] In an exemplary embodiment, the sensing and alarm module 3 includes: a smoke sensor, a temperature sensor and an alarm; the alarm is a buzzer and / or an alarm flash 9. For easy detection, the alarm flash 9 is set on the control system wire box 10.

[0043] The smoke sensor is used to obtain smoke data in the charging cabinet cavity 4 and send the smoke data to the control module;

[0044] The temperature sensor is used to obtain temperature data in the charging cabinet cavity 4 and send the temperature data to the control module;

[0045] The alarm is used to give an alarm according to the control of the control module.

[0046] When the data collected by the smoke sensor and temperature sensor show that the temperature rises rapidly or toxic gases, smoke, etc. are generated, the alarm will sound an alarm under the control of the control module and emit a continuous warning sound. In the early stage of the fire, the alarm information of the emergency or dangerous incident is conveyed to the people around with the strongest signal, so that corresponding actions can be taken in time to prevent it.

[0047] In order to be more environmentally friendly and cost-effective compared with other fire extinguishing agents (dry powder or aerosol), the fire extinguishing module includes: a solenoid valve 5, a water inlet pipe 6, a water outlet pipe 11 and a water level sensing needle 8;

[0048] One end of the water inlet pipe 6 is connected to the water inlet provided on the side wall of the charging cabinet cavity 4; the other end of the water inlet pipe 6 is connected to the faucet;

[0049] The water outlet pipe 11 is connected to the water outlet provided at the bottom of the charging cabinet cavity 4;

[0050] The solenoid valve 5 is arranged on the water inlet pipe 6 and connected to the control module; the solenoid valve 5 is used to open under the control of the control module when the temperature and smoke data in the charging cabinet cavity 4 exceed the set threshold value, so that water flows into the charging cabinet cavity 4;

[0051] The water level sensing needle 8 is arranged on the side wall of the charging cabinet cavity 4 and connected to the control module; the water level sensing needle 8 is used to obtain water level data and send the water level data to the control module; the control module is also used to control the electromagnetic valve 5 to close when the water level data exceeds the set value. Due to the injection of water flow, the temperature in the charging cabinet cavity 4 is automatically reduced, and the possible harmful gases are diluted, thereby effectively curbing the occurrence of danger.

[0052] From the above, it can be seen that the fire extinguishing module uses water as the fire extinguishing agent. At the same time, when water is used as the fire extinguishing agent, there is no need to consider the storage and replacement of the fire extinguishing agent. As long as the water inlet pipe 6 is connected to the faucet, the fire can be safely extinguished while ensuring the cost. It is practical and economical, and has substantial technical characteristics and significant effects of energy saving and emission reduction.

[0053] In order to ensure the overall operation, the electric bicycle charging cabinet further includes: a power supply module;

[0054] The power supply module is respectively connected to the explosion-proof module, the sensing and alarm module 3, the fire extinguishing module and the control module.

[0055] In an exemplary embodiment, the power supply module is a control system wire box 10 .

[0056] In order to facilitate movement and fixation, the electric bicycle charging cabinet further includes: a fixed pulley 12 and a universal pulley 7;

[0057] The fixed pulley 12 and the universal pulley 7 are arranged at the bottom of the charging cabinet cavity 4. The fixed pulley 12 and the universal pulley 7 are installed at the four corners of the bottom of the charging cabinet cavity 4;

[0058] When the battery is charging, the safety charging cabinet is equivalent to a closed charger, which ensures the normal charging of the battery, can contain and dilute the gas generated by thermal runaway of the battery, and prevent the high-temperature and high-pressure gas from gathering in a limited space and exploding in the event of a fire. If the fire occurs very quickly, the explosion can be prevented by promptly opening the explosion-proof upper cover door 2, thereby improving the safety of battery storage and charging.

[0059] This application effectively integrates multiple technologies such as monitoring, early warning, and fire extinguishing, forming an innovation of "early warning → intelligent response → efficient fire extinguishing" for charging cabinets, protecting the charging safety of electric bicycles to the greatest extent.

[0060] This application has the functions of automatic collection, early warning alarm and automatic sensing intelligent control, and realizes high-safety charging, high-precision warning and intelligent response of solenoid valve 5 to spray the required dose of fire extinguishing agent. In addition, this application uses water as the fire extinguishing agent; water has the advantages of good fire extinguishing effect, green environmental protection, low cost, and no need to consider the storage and replacement of fire extinguishing agent.

[0061] like Figure 3 As shown, this application can achieve early warning and control by fully understanding and mastering the thermal runaway process and characteristics of lithium-ion batteries, and truly nip the fire in the bud. Figure 4 The experimental data temperature and voltage curves shown also significantly reflect the excellent effect of the present application. The present application can quickly reduce the temperature of the battery, and the battery voltage remains normal during the whole process. It can be seen that the present application has an absolute advantage over the existing charging cabinets. In addition, compared with the shared charging piles and existing charging cabinets on the market, the present application has lower energy consumption, a small size, and occupies less space, and can be moved and placed for charging as needed.

[0062] In addition, the present application has made changes in the choice of fire extinguishing agent. The fire extinguishing agent of most charging cabinets on the market is dry powder or aerosol, while the present application uses water as the fire extinguishing agent. According to existing research on thermal runaway of lithium batteries, water is a fire extinguishing agent with better fire extinguishing effect. At the same time, when water is selected as the fire extinguishing agent, there is no need to consider the storage and replacement of the fire extinguishing agent. Compared with other fire extinguishing agents, it is more green, energy-saving and environmentally friendly, and it also reduces the cost of use, and there is no need to purchase fire extinguishing agents. Just turn on the faucet to extinguish the fire, without having to consider issues such as purchasing fire extinguishing agents and validity periods. It can be seen that the present application is both practical and economical, and has substantial technical characteristics and significant effects of energy saving and emission reduction.

[0063] The technical features of the above embodiments may be combined arbitrarily. To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0064] This article uses specific examples to illustrate the principles and implementation methods of this application. The description of the above embodiments is only used to help understand the method and core ideas of this application. At the same time, for those skilled in the art, according to the ideas of this application, there will be changes in the specific implementation methods and application scope. In summary, the content of this specification should not be understood as limiting this application.
