[0002] As traffic pressure continues to increase, electric bicycles have become an important means of transportation for many people. Although electric bicycles are convenient and fast, they often cause fires. In order to protect the safety of people's lives and property, plans have been formulated to strengthen the construction of electric bicycle full-chain and centralized charging facilities. Among them, it is mentioned that existing residential areas are encouraged to vigorously promote the construction of charging facilities in residential areas in full coverage according to the installation principle of "charging (changing) cabinets as the main and charging piles as the auxiliary" according to local conditions. However, during the frequent charging of batteries, especially lithium batteries, in charging and swapping cabinets, thermal runaway is likely to occur due to overcharging, overvoltage, short circuit and environmental reasons, thereby causing fires and resulting in safety accidents. Most of the charging and swapping cabinets currently installed are not equipped with automatic fire extinguishing devices, or are only equipped with ordinary fire extinguishers. This results in the inability to respond quickly to extinguish the fire and protect people's property safety once a fire occurs. After a fire occurs, it is also very easy to cause the batteries in adjacent charging and swapping cabins to be interlocked and catch fire. This results in the need to set up nozzles in each charging and swapping cabin in order to set up a fire extinguishing device, which increases production costs. Therefore, there is a great need for a charging and swapping cabinet that can automatically extinguish fires. While charging quickly, it also has the functions of detecting fires, quickly responding to fire extinguishing, and continuously cooling down to effectively prevent the re-ignition of fires. In addition, it can reduce equipment costs while also being a safe and reliable automatic fire extinguishing charging and swapping cabinet.

[0020] The present invention will be further described below in conjunction with the embodiments, but is not limited to the contents of the specification.

[0021] like Figures 1 to 4As shown, the utility model relates to an automatic fire extinguishing charging and swapping cabinet connected with a charging and swapping cabin, which includes a charging and swapping cabinet body 1, a fire extinguishing device 2, a controller 3 and a detector 4 capable of detecting fire. The interior of the charging and swapping cabinet body 1 is divided into two independent spaces at the top and the bottom by an isolation plate 11. The top space is an equipment cabin 12, and the fire extinguishing device 2 and the controller 3 are installed in the equipment cabin 12. The bottom space is a charging and swapping cabin 13. The charging and swapping cabin 13 is divided into a plurality of charging and swapping cabins 13 by a partition plate 14, and the plurality of charging and swapping cabins 13 are arranged longitudinally, and a gap space 15 is left between the two longitudinally arranged charging and swapping cabins 13. The fire extinguishing agent spray outlet of the fire extinguishing device 2 faces the gap space. 15, the gap space 15 is connected with the inside of each adjacent charging and swapping cabin 13 to form a diffusion channel for the fire extinguishing agent to diffuse to each charging and swapping cabin 13, the detector 4 is installed in the charging and swapping cabin 13 and / or the gap space 15, the controller 3 is respectively connected with the fire extinguishing device 2 and the detector 4 signal to form a control feedback circuit, when in use, the battery of the electric vehicle is placed in the charging and swapping cabin 13, and after the cabinet door is closed, during the charging process, if a fire occurs, in the stage of smoke generation before the fire has an obvious trend, or in the early stage of the fire, the detector 4 arranged in the gap space 15 and / or the charging and swapping cabin 13 can detect the fire and convert it into a feedback signal through the controller The control line transmits the start signal to the controller 3, and the controller 3 transmits the start signal to the fire extinguishing device 2 through the control line. The fire extinguishing device 2 is started, and the fire extinguishing agent is sprayed from the fire extinguishing agent outlet into the gap space 15. Specifically, the fire extinguishing device 2 uses a gas fire extinguishing device. Since the gap space 15 is connected to the inside of each adjacent charging and swapping cabin 13, no matter which charging and swapping cabin 13 has a fire, the gas fire extinguishing agent sprayed into the gap space 15 can enter each charging and swapping cabin 13 through the passage. At the same time, the fire extinguishing agent outlet is set at the top of the gap space, which can enable the fire extinguishing agent outlet to achieve rapid full flooding fire extinguishing from top to bottom, because the battery has a tendency to ignite and then the fire becomes larger. The process is relatively short, and as the temperature rises, it is easy to cause fire in the adjacent charging and swapping cabin 13. If accurate fire extinguishing is to be achieved, it is necessary to set up complicated fire extinguishing agent delivery pipelines. The charging and swapping cabinet of the present application has a spatial structure that is connected to each charging and swapping cabin 13 through the gap space 15, which can reduce the use of fire extinguishing agent delivery pipelines, nozzles and other equipment, simplify equipment pipelines, and reduce equipment costs; in addition, the isolation plate 11 isolates the lower charging compartment and the upper equipment compartment, which can protect the safety of the fire extinguishing equipment 2 when a fire occurs, ensuring that it can be used normally and extinguish the fire smoothly. The controller 3 can use the Lida LD550 series related small and medium-sized gas fire extinguishing controllers.

[0022] Preferably, the type of gas fire extinguishing agent used is perfluorohexanone fire extinguishing agent, which mainly relies on heat absorption cooling to extinguish fire and reduce temperature, has the characteristics of fast fire extinguishing speed, good cooling effect, good insulation performance, and is an environmentally friendly fire extinguishing agent.

[0023] A number of evenly arranged through holes 16 are provided on the partition plate 14, forming a mesh structure in which all the charging and swapping compartments 13 in the charging and swapping cabinet 1 can be interconnected and the fire extinguishing agent can diffuse freely. The dense through holes 16 are arranged on the partition plate 14, so that the gap space 15 and each charging and swapping compartment 13 can be better connected. When the detector 4 collects the fire signal, or when the fire extinguishing agent is sprayed into the gap space 15 and then flows into each charging and swapping compartment 13, it can be more easily realized, thereby improving the efficiency of fire signal collection and the fire extinguishing agent entering the charging and swapping compartment 13 to extinguish the fire.

[0024] The charging and swapping cabinet 1 is a box structure with an internal accommodating space formed by a top plate 101, a back plate 102, a bottom plate 103, a side plate 104 and a cabinet door 105. There are multiple cabinet doors 105 and they are arranged corresponding to the charging and swapping cabin 13 and the equipment cabin 12. Specifically, the top plate 101, the back plate 102, the bottom plate 103, the side plate 104 and the cabinet door 105 can be arranged independently, which can facilitate transportation and complete the assembly work when reaching the facility installation point. In addition, an independent cabinet door can also be arranged at the equipment cabin 12 to facilitate regular maintenance, inspection and replacement of the fire extinguishing device 2 and the controller 3.

[0025] The detector 4 includes a composite detector 41 and a temperature detector 42. The composite detector 41 is fixedly installed on the top of the gap space 15. The number of temperature detectors 42 corresponds to the charging and swapping cabins 13, and they are installed on the top of each charging and swapping cabin 13. Specifically, the composite detector 4 is a detector with multiple probes, which can detect different types of combustible gases and smoke, such as carbon monoxide, hydrogen, VOC, smoke, etc., and can timely detect and transmit signals of possible fire hazards in the charging and swapping cabin to the controller 3; the temperature detector 42 can detect the temperature in the space of the charging and swapping cabin 13, and when the temperature reaches a certain value, it will transmit a fire signal to the controller 3, because it is In order to reduce equipment costs and reduce the use of fire extinguishing agent delivery pipelines and nozzles, the internal partition plate structure of the charging and swapping cabinet of the utility model is a perforated plate. Relatively speaking, if a battery in a charging and swapping cabin 13 catches fire, the perforated plate structure makes it easier for the fire to affect the battery in the adjacent charging and swapping cabin 13, and a temperature detector 42 is arranged on the top of each charging and swapping cabin 13. In this way, the fire can be quickly discovered and the fire extinguishing agent flooding type fire can be quickly completed, so as to achieve the effect of improving the fire extinguishing efficiency and quickly control the fire. There will be no problem of fire affecting batteries in other charging and swapping cabins 13, and the gas fire extinguishing agent used will not affect the subsequent use of the battery.

[0026] The fire extinguishing device 2 includes a fire extinguishing agent bottle group 21, a fire extinguishing agent delivery pipeline 23, a nozzle 24 and a driving device 25. One end of the fire extinguishing agent delivery pipeline 23 is connected to the fire extinguishing agent bottle group 21 through the driving device 25, and the other end is connected to the nozzle 24. The driving device 25 is connected to the controller 3 by signal to form an opening mechanism of the fire extinguishing agent bottle group 21 controlled by the controller 3. When working, after receiving the fire signal from the detector 4, the controller 3 sends a working signal to the driving device 25 to start it. After receiving the starting signal, the driving device 25 will start to open the fire extinguishing agent bottle group 21, so that the fire extinguishing agent can be sprayed out from the bottle group. The fire extinguishing agent is delivered to the nozzle 24 along the fire extinguishing agent delivery pipeline 23. Under the action of pressure, the fire extinguishing agent is sprayed from the nozzle into the charging and swapping cabinet, and quickly submerges each charging and swapping cabin 13 to complete the fire extinguishing work.

[0027] The fire extinguishing device 2 also includes a master control valve 22, which is connected to the fire extinguishing agent delivery pipeline 23 and is connected to the controller 3 signal. The master control valve 22 adopts a normally closed pilot solenoid valve, which is opened when powered on and closed when powered off. It is connected to the controller 3 signal, and its power-on time is controlled by the start / shutdown signal issued by the controller 3, so as to achieve the purpose of controlling the fire extinguishing spraying dosage, and then realize the fire extinguishing agent components to be sprayed into the charging and swapping cabinet in batches. By controlling the amount of fire extinguishing agent sprayed each time, the purpose of rapid fire extinguishing, continuous cooling, fire suppression and prevention of re-ignition is achieved.

[0028] A leakage signal feedback device 26 and a start signal feedback device 27 are also provided at the bottle mouth of the fire extinguishing agent bottle group 21. The leakage signal feedback device 26 and the start signal feedback device 27 are connected to the inside of the fire extinguishing agent bottle group and are connected to the controller 3 signal to form a feedback control circuit. Specifically, the leakage signal feedback device 26 is a diaphragm pressure structure with reliable sealing. The pressure structure can reflect the pressure situation in the fire extinguishing agent bottle group. After the leakage pressure is reduced, it can respond quickly and send a signal to the controller 3, so as to achieve the effect of real-time display of whether the fire extinguishing agent bottle group is leaking; the start signal feedback device 27 is a self-locking diaphragm pressure structure and is provided with a reset button. The start signal that is self-locked after the manual reset action can be and can only be reset manually, which not only ensures the safe transmission of the start signal during a fire, but also can be manually released after the fire is extinguished.

[0029] The fire extinguishing agent delivery pipeline 23 is a flexible and bendable pipe, and each interface connection is a quick-insert or quick-twist joint. The fire extinguishing agent delivery pipeline 23 can adapt to various installation environments and installation conditions. The shape of the pipe is not restricted, which is convenient for installation and layout. The interface connection uses quick-insert or quick-twist joints, which can reduce the difficulty of installation and maintenance. It is simple, firm and not easy to fall off.

[0030] The nozzle of the nozzle 24 passes through the isolation plate 11 and is arranged toward the bottom of the gap space 15. The spraying shape of the nozzle is conical. Setting it toward the bottom can enable the gas fire extinguishing agent to quickly flow into each charging and swapping cabin 13 from top to bottom, while trying to achieve uniform spraying, further accelerating the flooding speed of the fire extinguishing agent and improving the fire extinguishing efficiency.

[0031] To sum up, the fire extinguishing working logic of the entire fire extinguishing charging and swapping cabinet is: when a fire occurs, the alarm controller 3 receives the fire signal from the composite detector 4 and sends out an early warning signal. For example, the composite detector 4 detects that the carbon monoxide concentration reaches the set ppm value, such as 190ppm±50ppm, and the alarm controller 3 sends out a fire warning signal; when the fire develops further, the starting temperature of the temperature detector 5 is triggered. For example, when the temperature detector 5 in the charging and swapping cabin B detects that the temperature reaches the set alarm temperature, such as 80℃±5℃, the alarm controller 3 sends out a fire alarm signal. The fire extinguishing device 2 is automatically started at the same time, and the driving device 25 is powered to start, opening the fire extinguishing agent bottle group 21. The fire extinguishing agent stored in the fire extinguishing agent bottle group 21 is sprayed into all the charging and swapping cabins through the fire extinguishing agent delivery pipeline 23 and the main control valve 22 by the nozzle 24, and fire extinguishing and cooling are implemented according to the set spraying strategy. The spraying strategy referred to here is the set opening and closing interval of the main control valve, that is, when the fire extinguishing agent bottle group 21 is opened, the controller intermittently energizes the main control valve 22 for 2 to 3 times in 3 minutes, and controls the amount of fire extinguishing agent sprayed each time according to the set power-on time, so as to achieve the purpose of rapid fire extinguishing, continuous cooling, and fire suppression to prevent re-ignition. Finally, the fire extinguishing operation is completed to protect the safety of people and property.
