Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0049] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0050] It should be noted that the directional terms such as "up" and "down" in the following text are defined based on the accompanying drawings in the instruction manual.

[0051] The core of this utility model is to provide a fire extinguishing device for electric bicycle charging sheds, which can be detected in time when a fire occurs in the charging shed and can be extinguished quickly to prevent the fire from spreading.

[0052] Please refer to Figure 1 , Figure 2 and Figure 3 A fire extinguishing device for electric bicycle charging sheds includes a monitoring component 1, a nozzle assembly 2, a high-pressure spray device 3, and a control device 4.

[0053] Specifically, monitoring component 1 is installed inside the charging shed, high-pressure spray device 3 is installed inside the charging shed, and control device 4 is signal-connected to both monitoring component 1 and high-pressure spray device 3. Control device 4 controls the operating status of monitoring component 1 and high-pressure spray device 3. Monitoring component 1 is used to monitor the temperature and smoke concentration inside the charging shed in real time and sends the real-time temperature and smoke concentration signals to control device 4. High-pressure spray device 3 is connected to nozzle assembly 2, which is installed inside the charging shed. When the temperature and smoke concentration signals received by control device 4 both exceed preset values, control high-pressure spray device 3 to supply water to nozzle assembly 2, and spray water onto the charging shed through nozzle assembly 2. High-pressure spray device 3 is connected to an external water source, and while extinguishing the fire, the water source continuously supplies water to high-pressure spray device 3 to ensure that there is always sufficient water in high-pressure spray device 3 to supply nozzle assembly 2 until the fire is extinguished.

[0054] The fire extinguishing device installed in the electric bicycle charging shed using the above method can promptly detect fires inside the charging shed and activate the fire extinguishing device to put out the fire, thereby improving fire extinguishing efficiency.

[0055] In the above embodiment, the high-pressure spray device 3 includes a housing 31, a water tank 5 is provided inside the housing 31, the water tank 5 is connected to a water supply pipe 51 and a water outlet pipe 52, the housing 31 is provided with a through hole through which the water supply pipe 51 and the water outlet pipe 52 pass, the water supply pipe 51 is connected to a water source, and the water outlet pipe 52 is connected to the nozzle assembly 2.

[0056] It should be noted that the water source replenishes water to the water tank 5 through the water supply pipe 51, and the water in the water tank 5 supplies water to the nozzle assembly 2 through the water outlet pipe 52 so that the nozzle assembly 2 can spray water.

[0057] In the above situation, the water outlet pipe 52 is equipped with a water outlet ball valve 6, a plunger pump 7, a pressure gauge 8 and a pressure transmitter 9. The plunger pump 7 is connected to the motor 10, and both the motor 10 and the pressure transmitter 9 are connected to the control device 4 via signal.

[0058] It is understandable that the motor 10 is controlled by the control device 4 to drive the plunger pump 7 to start, so that the water in the water tank 5 is discharged from the outlet pipe 52. The outlet pressure of the water pipe 52 is displayed in real time by the pressure gauge 8, and the outlet pressure of the outlet pipe 52 is detected in real time by the pressure transmitter 9. The real-time detected pressure data is sent to the control device 4, and the water pressure is displayed by the control device 4.

[0059] Among them, the outlet ball valve 6 is a normally open valve.

[0060] In this embodiment, seven sets of high-pressure plunger pumps are used. They are reliable, stable and durable. The equipment and pipes are made of stainless steel and high-pressure hoses, resulting in a long service life and high reliability.

[0061] Furthermore, the water supply pipe 51 is equipped with a filter 11, an inlet ball valve 12, and a float valve 13 in sequence. The inlet ball valve 12 is a normally open valve, and the float valve 13 is located inside the water tank 5. The water tank 5 is equipped with a low liquid level sensor and a first overflow pipe 14. Both the filter 11 and the low liquid level sensor are connected to the control device 4 via signal.

[0062] It should be noted that the water entering water tank 5 is filtered by filter 11 to ensure the cleanliness of the water entering water tank 5. When the water level in water tank 5 reaches the position of float valve 13, float valve 13 automatically closes to prevent water supply pipe 51 from continuing to supply water to water tank 5. When the water level in water tank 5 is lower than the position of float valve 13, float valve 13 automatically opens to allow water supply pipe 51 to continue supplying water to water tank 5. At the same time, when float valve 13 is damaged, the water level in water tank 5 can be detected in real time by a low liquid level sensor. When the water level in water tank 5 reaches the low liquid level detected by the low liquid level sensor, a signal is sent to control device 4, and control device 4 issues an alarm to prompt personnel to carry out maintenance. When the water level is higher than the position of float valve 13, the water in water tank 5 can be drained through the first overflow pipe 14.

[0063] The system includes an outlet ball valve 6 and an inlet ball valve 12 to facilitate the maintenance and repair of the water tank 5. The filter sludge in the filter 11 should be cleaned at least once a month, and the frequency of checks can be increased depending on the usage frequency. The condition of the water tank 5 should be checked, and the water in the tank 5 should be cleaned and replaced promptly to prevent long-term water deterioration.

[0064] The float valve 13 automatically controls the liquid level in a water tower or pool using a crank arm and a float. It is simple to maintain, flexible and durable, provides high accuracy in level control, is unaffected by water pressure, and opens and closes tightly without leakage. The float valve 13 regulates the liquid supply by controlling the liquid level.

[0065] In the above embodiment, the box 31 is also provided with a medicine box 15. The medicine box 15 is connected to the plunger pump 7 through a medicine pipe 151. A manual ball valve 16 is provided on the medicine pipe 151. The manual ball valve 16 is a normally closed valve. A second overflow pipe 17 is provided in the medicine box 15.

[0066] Understandably, when fire extinguishing agents are needed, staff will open the manual ball valve 16 to allow the agent in the agent tank 15 to flow out through the agent pipe 151, mix with water through the plunger pump 7, and finally spray it through the nozzle assembly 2.

[0067] When staff replenish fire extinguishing agent to the agent tank 15, if the agent level in the agent tank 15 is higher than the second overflow pipe 17, it will be discharged outward through the second overflow pipe 17 to avoid excessive agent.

[0068] The advanced, efficient, and environmentally friendly fire extinguishing agent not only improves fire extinguishing efficiency but also requires less water, resulting in minimal water damage and causing no harm to the environment or equipment. When used in carports, it provides rapid fire suppression and also has smoke and dust removal capabilities.

[0069] In the above embodiment, a breather valve 20 is provided on the top of both the water tank 5 and the medicine tank 15 to prevent the water tank 5 from forming a negative pressure when the plunger pump 7 starts, as the amount of water in the water tank 5 decreases. The same applies to the medicine tank 15.

[0070] The breather valve 20 consists of a pressure valve and a vacuum valve, and is installed on the water tank 5 and the medicine tank 15. It automatically opens and closes according to the positive and negative pressure changes of the oil and gas preparations inside the water tank 5 and the medicine tank 15, maintaining the pressure difference between the inside and outside of the water tank 5 and the medicine tank 15 within the allowable range. When the pressure of the medium inside the water tank 5 and the medicine tank 15 is within the control operating pressure range of the breather valve 20, the breather valve 20 does not operate, maintaining the airtightness of the water tank 5 and the medicine tank 15. When medium is added to the water tank 5 and the medicine tank 15, causing the pressure in the upper gas space of the water tank 5 and the medicine tank 15 to rise and reach the operating positive pressure of the breather valve 20, the pressure valve is opened, and gas escapes from the exhalation outlet of the breather valve 20, preventing the pressure inside the water tank 5 and the medicine tank 15 from continuing to increase. When the medium is drawn out of the medicine tank 15, the pressure in the upper gas space of the water tank 5 and the medicine tank 15 decreases. When the pressure reaches the operating negative pressure of the breather valve 20, the atmosphere outside the water tank 5 and the medicine tank 15 will open the negative pressure valve disc of the breather valve 20, allowing outside gas to enter the water tank 5 and the medicine tank 15. This prevents the pressure inside the water tank 5 and the medicine tank 15 from decreasing further, and balances the air pressure inside the water tank 5 and the medicine tank 15 with the air pressure outside the water tank 5 and the medicine tank 15, thus protecting the safety devices of the water tank 5 and the medicine tank 15.

[0071] Among them, the high-pressure spray device 3 is an integrated main unit that is fixedly installed.

[0072] To ensure the reliable operation of the fire extinguishing device, it must be cleaned after each use of the mixed extinguishing agent. The cleaning process is as follows: First, close the manual ball valve 16 below the agent tank 15, then connect the fire water supply to fill the water tank 5, and start the plunger pump 7 until no extinguishing agent appears in the sprayed water; then stop the plunger pump 7; after draining the remaining water in the water tank 5, refill the water tank 5 with water and replenish the extinguishing agent in a timely manner.

[0073] Based on the above embodiment, the control device 4 is provided in the housing 31. The control device 4 includes a controller and an emergency start button and an emergency start / stop button connected to the controller. The housing 31 is provided with a through hole for exposing the emergency start button and the emergency start / stop button. The housing 31 is also provided with a wiring hole.

[0074] It should be noted that when a fire occurs in the charging shed, but the control device 4 does not detect it and the fire extinguishing procedure is not activated, the staff can turn on the high-pressure spray device 3 through the emergency start button, causing the controller to send a fire extinguishing command to the motor 10 to drive the plunger pump 7 to run and activate the fire extinguishing procedure. When there is no fire in the charging shed, but the fire extinguishing procedure has already been activated, the staff can use the emergency start / stop button to send a stop command to the motor 10, causing the plunger pump 7 to stop running and thus shut down the fire extinguishing procedure.

[0075] In the above embodiment, the charging shed is also equipped with an alarm light 18 and a sound-activated alarm 19, both of which are connected to the controller signal.

[0076] Understandably, when a fire occurs, the controller will simultaneously send instructions to the alarm light 18 and the audible alarm 19, causing the alarm light 18 to provide a visual display and the audible alarm light 19 to provide an audible alert, so as to prompt staff or passersby to rush to the charging shed as soon as possible.

[0077] In a preferred embodiment, the monitoring component 1 includes a temperature detector 101 and a smoke detector 102. Both the temperature detector 101 and the smoke detector 102 are connected to the controller signal. Multiple temperature detectors 101 and smoke detectors 102 are provided and distributed in different locations in the charging shed.

[0078] It should be noted that temperature detector 101 is used to detect the temperature inside the charging shed in real time and sends the measured temperature signal to the controller in real time. The controller determines whether the temperature inside the charging shed is higher than the temperature at which a fire would occur. Smoke detector 102 is used to detect the smoke concentration inside the charging shed in real time and sends the measured smoke concentration signal to the controller in real time. The controller determines whether the smoke concentration inside the charging shed is higher than the smoke concentration at which a fire would occur. When the controller determines that both the temperature and smoke concentration inside the charging shed exceed the standard for a fire, the controller controls motor 10 to start, driving plunger pump 7 to pump water, which is then sprayed onto the charging shed through nozzle assembly 2 to extinguish the fire.

[0079] In the above case, the nozzle assembly 2 includes a water spray pipe 21 connected to the water outlet pipe 52. The water spray pipe 21 is connected to at least two parallel branch water pipes 22. The branch water pipes 22 are provided with multiple spray heads 23, which are distributed in different positions in the charging shed.

[0080] Understandably, by setting up sprinkler pipes 21, it is possible to achieve zoned layout, so as to accurately distribute them to places where fires may occur, and achieve precise fire extinguishing.

[0081] Among them, spray head 23 is a 150° wide-angle spray.

[0082] In the above embodiments, each branch water pipe 22 is provided with an electric valve 24 for controlling the opening and closing of the branch water pipe 22, and the electric valve 24 is connected to the controller signal.

[0083] It should be noted that when a fire occurs, the temperature detector 101 and smoke detector 102 in the corresponding area of ​​the charging shed can first detect the temperature signal and smoke concentration signal, and send the signal to the controller. The controller then controls the electric valve 24 on the branch water pipe 22 in the corresponding area to open, so as to achieve precise control of the fire in the corresponding area of ​​the charging shed.

[0084] Under normal circumstances, the fire situation in the charging shed is monitored and detected in real time by smoke detector 102 and temperature detector 101. When only smoke detector 102 or temperature detector 101 sends a fire signal, the device will not alarm. When a fire occurs in an electric bicycle being charged in the charging shed, two or more detectors will send fire signals to the controller at the same time. The controller will process the fire information and treat it as a fire alarm. At the same time, the controller will activate the alarm light 18 and the sound alarm 19, start the motor 10 of the fire extinguishing device, start the plunger pump 7 and the zone control electric valve 24, and spray high-pressure water mist for fire extinguishing within the specified time limit.

[0085] In the event of a fire in the charging shed, if the temperature detector 101 and smoke detector 102 fail to detect the fire due to unforeseen environmental factors, on-site personnel can immediately activate the emergency start button to forcibly start the controller, which will then immediately activate the fire extinguishing device to extinguish the fire.

[0086] If there is no fire in the charging shed, but environmental or unpredictable circumstances cause the temperature detector 101 and smoke detector 102 to issue fire information and activate the fire extinguishing device, on-site personnel can press the emergency start / stop button in time to stop the operation of the fire extinguishing device.

[0087] After the fire in the charging shed is extinguished, on-site personnel will confirm that the fire is out and then turn off the emergency start / stop button to stop the fire extinguishing equipment from operating.

[0088] In summary, the fire extinguishing device for electric bicycle charging sheds provided by this utility model applies high-pressure spray fire extinguishing technology to the fire monitoring, detection, and extinguishing of charging sheds. It provides strong protection for the residential community and the public areas of the charging shed by enabling timely monitoring, detection, and extinguishing of initial fires in the charging shed and preventing the fire from spreading further.

[0089] This device occupies a small area, is easy to maintain, and has a large protection area. A single device can provide protection for a single area or multiple areas, or multiple devices can be combined to provide protection for multiple areas, making it economical and practical.

[0090] It should be noted that in this specification, relational terms such as first and second are used only to distinguish one entity from several other entities, and do not necessarily require or imply any such actual relationship or order between these entities.

[0091] The various embodiments in this specification are described in a progressive manner, with each embodiment focusing on the differences from other embodiments. The same or similar parts between the various embodiments can be referred to each other.
