Technical Field

[0001] The utility model belongs to the technical field of fire protection, and particularly relates to a fire extinguishing system for an electric bicycle charging shed. Background Art

[0002] With the improvement of fire prevention measures, most electric bicycle charging sheds are currently equipped with detectors for detecting fires, and generally use smoke detectors, temperature detectors or simple spectral detectors. However, for electric bicycle charging sheds installed outdoors, due to the changeable outdoor environment, the above detectors are affected by environmental factors and cannot be well applied, resulting in the spread of fires due to failure to accurately and timely detect fires.

[0003] Therefore, the existing technology needs to be improved and developed. Utility Model Content

[0004] The purpose of the utility model is to provide an electric bicycle charging shed fire extinguishing system, which solves the problem that detectors in outdoor electric bicycle charging sheds are affected by environmental factors and cannot accurately and timely detect fires. It can accurately distinguish between flames and interference sources and achieve the effect of timely prevention and control.

[0005] In the first aspect, the utility model provides an electric bicycle charging shed fire extinguishing system, comprising a main unit, a liquid storage tank and a spray device, wherein the main unit is connected to the liquid storage tank and the spray device and can control the connection between the liquid storage tank and the spray device so that the liquid medium stored in the liquid storage tank is sprayed out from the spray device, the spray device is provided with at least one spray area, each of the spray areas is equipped with a flame detector, and the flame detector comprises an infrared pyroelectric sensor and a day-blind ultraviolet photoelectric sensor.

[0006] The electric bicycle charging shed fire extinguishing system provided by the utility model utilizes infrared pyroelectric sensors and solar-blind ultraviolet photoelectric sensors to distinguish between interference sources in the outdoor environment and flames in the charging shed, thereby accurately judging the fire and preventing and suppressing it in a timely manner, effectively ensuring personal safety and reducing property losses.

[0007] Furthermore, each of the spray areas is provided with a plurality of nozzles, the plurality of nozzles are arranged in the charging shed and the flame detector is located on any one side or both sides of the left and right sides of the charging shed.

[0008] Ensure that the flame detector can detect flames at all locations in the entire charging shed, effectively improving overall reliability and safety.

[0009] Furthermore, each of the spraying areas is equipped with a circuit breaker, which is directly connected to the corresponding flame detector through a first relay and is used to cut off the power supply of the charging shed.

[0010] This saves time in processing signals and helps improve signal transmission efficiency, thereby ensuring that the power supply to the charging shed is cut off at the moment a fire occurs, thereby avoiding causing a larger fire.

[0011] Furthermore, the spray device is provided with a plurality of the spray areas, each of the spray areas is provided with a solenoid valve, and the solenoid valve is directly connected to the corresponding flame detector via a second relay and is used to control the on and off of the spray device.

[0012] This saves time in processing signals and helps improve signal transmission efficiency, thereby ensuring that the sprinkler device is turned on at the moment a fire occurs, thereby ensuring that the liquid medium can flow through the entire sprinkler device and be sprayed out from the sprinkler head in the first place.

[0013] Furthermore, the nozzle is a centrifugal atomizing nozzle.

[0014] Furthermore, the host is provided with a dialer and / or a remote controller.

[0015] Furthermore, the liquid storage tank is a cold-resistant water tank.

[0016] Furthermore, each of the spraying areas is provided with a camera, which is installed on the charging shed and is used to monitor the charging shed.

[0017] Furthermore, it also includes a monitoring machine, which is connected to all the cameras and is provided with a first sound and light alarm.

[0018] Furthermore, each of the spraying areas is provided with a second sound and light alarm, and the second sound and light alarm is installed in the charging shed.

[0019] From the above, it can be seen that the electric bicycle charging shed fire extinguishing system of the utility model simultaneously deploys infrared pyroelectric sensors and day-blind ultraviolet photoelectric sensors to replace traditional detectors, so that the detectors can be placed outdoors and can accurately distinguish between flames and interference sources, which is conducive to timely control of fires and achieves the effect of preventing the spread of fire, thereby ensuring personal safety and reducing property losses.

In addition, the utility model provides various specific examples of processes and materials, but those of ordinary skill in the art may be aware of the application of other processes and / or the use of other materials.

[0030] It should be noted that the “left and right directions” mentioned below are based on the Figure 1 The direction of the arrow is used as a reference, and the left and right direction is the length direction of the charging shed 500.

[0031] Reference Figure 1 and attached Figure 2 The utility model provides an electric bicycle charging shed fire extinguishing system, including a main unit 100, a liquid storage tank 200 and a spray device 300. The main unit 100 is connected to the liquid storage tank 200 and the spray device 300 and can control the liquid storage tank 200 and the spray device 300 to be connected so that the liquid medium stored in the liquid storage tank 200 is sprayed out from the spray device 300. The spray device 300 is provided with at least one spray area 310, and each spray area 310 is installed with a flame detector 400. The flame detector 400 includes an infrared pyroelectric sensor and a day-blind ultraviolet photoelectric sensor (these two sensors are prior art, and their specific structures are not repeated here).

[0032] In this embodiment, the infrared pyroelectric sensor and the day-blind ultraviolet photoelectric sensor can quickly identify flames and distinguish interference sources in the outdoor environment by processing signals through the built-in microprocessor, thereby reducing the impact of outdoor environmental factors on flame detection, allowing the flame detector 400 to more accurately determine the fire and promptly feed back the fire signal to the host 100. When the host 100 receives the fire signal, it immediately connects the liquid storage tank 200 and the sprinkler device 300. The special foam fire extinguishing agent pre-stored in the liquid storage tank 200 is pumped into the sprinkler device 300 driven by a water pump and finally sprayed in the charging shed 500, thereby extinguishing the flame.

[0033] In actual applications, multiple spray areas 310 can be arranged according to the specific area of ​​the charging shed 500, which is helpful to ensure that each nozzle 320 in the spray device 300 sprays foam fire extinguishing agent at a preset pressure, thereby ensuring that the desired fire extinguishing effect is achieved.

[0034] In certain embodiments, referring to Figure 1 and attached Figure 2 Each spray area 310 is provided with a plurality of nozzles 320 , and the plurality of nozzles 320 are arranged in the charging shed 500 , and the flame detector 400 is located on any one side or both sides of the left and right sides of the charging shed 500 .

[0035] In this embodiment, when the length of the charging shed 500 is long, in order to ensure that the flame detector 400 can detect flames at various positions of the entire charging shed 500, the flame detector 400 can be arranged on both sides of the left and right sides of the charging shed 500, thereby improving the overall reliability and safety.

[0036] In certain embodiments, referring to Figure 1 and attached Figure 2 Each spraying area 310 is installed with a circuit breaker 330 , which is directly connected to the corresponding flame detector 400 through a first relay and is used to cut off the power supply of the charging shed 500 .

[0037] In this embodiment, when the flame detector 400 detects a flame, the flame signal will also be fed back to the first relay. The flame signal directly controls the action of the first relay without passing through any chip / processor during transmission, which saves the time for processing the signal and is beneficial to improving the signal transmission efficiency, thereby ensuring that the power supply of the charging shed 500 is cut off at the moment of the fire, thereby avoiding causing a larger fire.

[0038] In some embodiments, when the spray device 300 is only provided with one spray area 310, the spray area 310 may not be provided with an electromagnetic valve 340 to control the on and off of the spray device 300. When the flame detector 400 detects a fire, the main unit 100 controls the liquid storage tank 200 and the spray device 300 to be connected so that the nozzle 320 can spray the foam fire extinguishing agent.

[0039] In certain embodiments, referring to Figure 1 The spray device 300 is divided into a plurality of spray areas 310 , each spray area 310 is installed with a solenoid valve 340 , and the solenoid valve 340 is directly connected to the corresponding flame detector 400 through a second relay and is used to control the on and off of the spray device 300 .

[0040] In actual applications, the initial stage of a fire is generally an open flame in a certain position or area in the charging shed 500. This embodiment performs zoning management on the charging shed 500, and only needs to control the corresponding spray area 310 to spray foam fire extinguishing agent at the position or area where the open flame appears to extinguish the flame, thereby avoiding unnecessary waste of resources and achieving a more efficient and flexible processing effect.

[0041] In this embodiment, the solenoid valve 340 serves as the gate of the sprinkler device 300 itself. When the flame detector 400 detects a flame, the flame signal is also fed back to the second relay. The flame signal directly controls the action of the second relay without passing through any chip / processor during transmission, which saves the time for processing the signal and is beneficial to improving the signal transmission efficiency, thereby ensuring that the sprinkler device 300 is turned on at the moment of the fire, thereby ensuring that the liquid medium can flow through the entire sprinkler device 300 and be sprayed out from the nozzle 320 in the first time.

[0042] It should be noted that the host 100 serves as a gate between the liquid storage tank 200 and the spray device 300. In the absence of a fire, it can prevent the liquid medium in the liquid storage tank 200 from being transported to the spray device 300. Therefore, during daily use, there is no liquid medium in all the pipes of the spray device 300, thereby preventing the liquid medium from freezing in the pipes due to low temperature and affecting the normal operation of the spray device 300.

[0043] In some embodiments, the nozzle 320 is a centrifugal atomizing nozzle.

[0044] Fires in electric bicycle charging sheds are generally caused by thermal runaway of the batteries in the electric bicycles, which generates open flames and a large amount of heat and triggers thermal runaway of surrounding batteries, thus forming a chain reaction and causing violent combustion in a short period of time. Therefore, dealing with such fires often requires rapid cooling of the batteries and rapid suppression of the flames. The centrifugal atomizing nozzle arranged in this embodiment can instantly cover the spray area 310 with water mist, thereby reducing the thermal radiation effect of the battery jet fire in the electric bicycle, effectively suppressing and preventing the spread of the fire. At the same time, due to the small particle size of the water mist, its surface area is increased by more than 1,000 times relative to the same volume of liquid medium, so it can produce a rapid cooling effect, which is very suitable for extinguishing flames generated by battery combustion.

[0045] In some embodiments, a dialer and / or a remote controller is provided in the host 100. When a fire occurs, the dialer can automatically call relevant personnel through offline dialing or online networking to ensure that the fire can be handled in the first time; and the remote controller enables the user to remotely control the entire system through the terminal, which is conducive to remote management.

[0046] In some embodiments, the liquid storage tank 200 is a cold-resistant water tank, and the connectors and piping structures of the cold-resistant water tank are wrapped with thermal insulation cotton, thereby preventing the liquid medium from freezing in the connectors and piping structures due to low temperature, making it suitable for various extreme weather conditions and ensuring normal operation at all times.

[0047] In certain embodiments, referring to Figure 1 and attached Figure 2 Each spray area 310 is provided with a camera 350, which is installed on the charging shed 500 and is used to monitor the charging shed 500. With the help of real-time images, fires can be discovered faster and more accurately, thereby improving overall reliability and safety.

[0048] In certain embodiments, referring to Figure 1 The electric bicycle charging shed fire extinguishing system also includes a monitoring machine 600, which is connected to all cameras 350 and is provided with a first sound and light alarm 610. The monitoring machine 600 comprehensively monitors each position of the charging shed 500 and promptly reminds relevant personnel to handle it with sound and light signals when a fire occurs.

[0049] In certain embodiments, referring to Figure 1 and attached Figure 2 Each spray area 310 is provided with a second sound and light alarm 360, which is installed in the charging shed 500. When a fire occurs, it uses sound and light signals to warn surrounding personnel to stay away from danger and remind relevant personnel to deal with it.

[0050] In the description of this specification, the description with reference to the terms "one embodiment", "certain embodiments", "illustrative embodiments", "examples", "specific examples", or "some examples" means that the specific features, structures, materials, or characteristics described in conjunction with the embodiments or examples are included in at least one embodiment or example of the utility model. In this specification, the schematic representation of the above terms does not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials, or characteristics described may be combined in any one or more embodiments or examples in a suitable manner.

[0051] The above are only some embodiments of the present invention. For those skilled in the art, several modifications and improvements can be made without departing from the inventive concept of the present invention, which all belong to the protection scope of the present invention.
