Description

Technical Field

[0001] The present invention relates to the technical field of power exchange cabinets, and in particular to an intelligent power exchange cabinet for water fire fighting. Background Art

[0002] Battery swap cabinets are important facilities for battery replacement and storage. As usage increases, battery fires in battery swap cabinets are becoming more common. To ensure the safety of battery swap cabinets during use, existing technologies mainly use aerosol fire extinguishing systems and water fire extinguishing systems for fire prevention and control.

[0003] Although aerosol fire extinguishing agents can suppress fire sources to a certain extent, they are not effective enough and the fire extinguishing process is relatively slow, so they cannot effectively extinguish battery fires in a short period of time. As a traditional fire extinguishing method, water fire extinguishing systems are widely used, but their effectiveness in battery swap cabinets is also subject to many restrictions. At present, water fire extinguishing systems mainly use the following methods: Water immersion fire extinguishing requires ensuring the tightness of the door of the battery swap cabinet so that the fire can be extinguished by flooding the battery with water when a fire occurs. However, as the sealing strip ages with the increase of service life, the sealing gradually fails, resulting in the water immersion fire extinguishing system may not be able to provide effective protection in long-term use. At the same time, water immersion fire extinguishing has a certain delay, and the fire can only be extinguished by flooding after the fire is triggered, which makes it difficult to respond to sudden fires quickly.

[0004] Fire sprinklers are passive fire extinguishers, which use passively triggered fire sprinklers to extinguish fires. However, due to its triggering method, it cannot respond in time at the early stage of a battery fire, and once triggered, the fire extinguishing process is uncontrollable, resulting in low fire extinguishing efficiency. In addition, the inability to accurately control the water flow and spraying range will also cause a certain degree of damage to the batteries, lines, etc. in the cabinet.

[0005] The battery drops into the water tank to extinguish the fire. This method uses the battery's own gravity to make it fall into the water tank below to extinguish the fire. However, since the battery will generate high temperature when it catches fire and may melt the plastic parts it contacts, the battery cannot be dropped into the water tank smoothly, thus affecting the fire extinguishing effect. In addition, this design requires a large space and is not very practical in actual applications.

[0006] At present, most water fire fighting systems do not perform well after a battery fire. They cannot extinguish the fire in a timely and effective manner. In addition, the fire will cause damage to the lines and other equipment in the cabinet during the spread of the fire, further causing the fire fighting system to fail and fail to play its due role.

[0027] Combine the following Figure 1-Figure 7 The water fire fighting intelligent power exchange cabinet of the present invention is described.

[0028] The water fire fighting intelligent power exchange cabinet provided in the embodiment of the present invention includes a power exchange cabinet body 10, multiple battery compartments 20, a water tank 30, a spray assembly and a heat-triggered fire sprinkler 50. Multiple battery compartments 20 are installed in the power exchange cabinet body 10. Figure 1 As shown, there are 12 battery compartments 20, 3 battery compartments 20 are installed in each row, and 4 rows are installed. The battery compartment 20 is used to accommodate batteries. The water tank 30 can be installed at the bottom of the power exchange cabinet body 10 to hold water. Each battery compartment 20 is provided with a spray assembly and a heat-triggered fire sprinkler 50, such as Figure 6 and Figure 7 As shown. Specifically, the water tank 30 is provided with a water inlet and a water outlet, and a water return hole 21 is provided at the bottom of the battery compartment 20. The input end of the spray assembly is connected to the water outlet of the water tank 30 through a pipeline, and the water return hole 21 is connected to the water inlet of the water tank 30 through a water return pipeline 90, forming a first loop. A heat-sensitive element is provided in the heat-triggered fire sprinkler 50. When a fire occurs, the ambient temperature rises and reaches the trigger temperature of the heat-triggered fire sprinkler 50. The heat-sensitive element will be activated, causing the sprinkler to open and automatically spray water to extinguish the fire. The input end of the heat-triggered fire sprinkler 50 is connected to the water outlet of the water tank 30 through a pipeline, and the water return hole 21 is connected to the water inlet of the water tank 30 through a water return pipeline 90, forming a second loop. It should be noted that when the sprinkler assembly is started and stopped by temperature control, the triggering temperature of the heat-triggered fire sprinkler head 50 is different from this temperature. For example, the triggering temperature of the heat-triggered fire sprinkler head 50 may be greater than the starting temperature of the sprinkler assembly. When the fire is small, the fire can be extinguished directly through a separate sprinkler assembly.

[0029] When a fire occurs in the battery compartment 20, the sprinkler assembly sprays the water in the water tank 30 into the battery compartment 20 to extinguish the fire. It should be noted that the activation mechanism of the sprinkler assembly includes: obtaining the temperature information in the battery compartment 20 through the temperature sensor, or the smoke information obtained through the smoke sensor, or the temperature information of the battery system to determine whether a fire occurs in the battery compartment 20. Based on the temperature information and / or the smoke information, the system can accurately determine whether it is necessary to activate the sprinkler assembly to extinguish the fire. After the battery catches fire, the temperature in the battery compartment 20 gradually rises. After reaching the trigger temperature of the trigger-type fire sprinkler, the heat-triggered fire sprinkler 50 is activated to spray water into the battery compartment 20 to extinguish the fire. The water sprayed into the battery compartment 20 by the sprinkler assembly and the heat-triggered fire sprinkler 50 flows back to the water tank 30 through the return water hole 21 and the return water pipeline 90, thereby realizing the recycling of water and ensuring that water can be sprayed continuously after the fire is triggered, and the fire can be controlled.

[0030] The water fire-fighting intelligent power exchange cabinet provided in the embodiment of the present invention, by arranging a sprinkler assembly and a heat-triggered fire sprinkler 50 in each battery compartment 20, adopts a combination of active fire protection and passive fire protection, effectively ensuring that the fire protection system can respond quickly and extinguish fires under various working conditions, preventing the fire from spreading to other components of the power exchange cabinet, thereby improving the safety of the power exchange cabinet.

[0031] Furthermore, the water fire fighting intelligent battery exchange cabinet also includes a temperature sensor and a controller. A temperature sensor is provided in each battery compartment 20, and the temperature sensor is used to obtain the temperature information in the corresponding battery compartment 20. The temperature sensor and the spray assembly are electrically connected to the controller respectively, and the controller is used to obtain the temperature information of the temperature sensor, and control the operation of the spray assembly based on the temperature information to achieve active control. Specifically, when the current temperature information obtained by the temperature sensor is higher than the warning temperature information, the controller controls the spray assembly to start, spray water toward the battery compartment 20 to extinguish the fire, and achieve controlled fire extinguishing.

[0032] The battery management system is electrically connected to the controller, and the battery management system can obtain the temperature information of the battery and transmit the temperature information to the controller. If the battery in the battery compartment 20 is abnormal and the battery temperature rises, and there is no open fire or smoke, the battery management system obtains the temperature information of the battery through the cable and transmits it to the controller, and the controller controls the spray assembly to start.

[0033] A fire has occurred inside the battery, and thick smoke has caused the temperature inside the battery compartment 20 to rise. After the temperature sensor detects that the temperature inside the battery compartment 20 is abnormal, it transmits the temperature information to the controller, and the controller controls the spray assembly to start.

[0034] When the battery explodes instantly, the time is short and the temperature sensor cannot respond quickly. At this time, the flame generated by the explosion will burn the heat-triggered fire sprinkler 50, and the heat-sensitive element in the heat-triggered fire sprinkler 50 will be activated, and automatically spray water into the battery compartment 20 to extinguish the fire.

[0035] The water tank 30 is arranged at the bottom of the battery exchange cabinet body 10, and a driving part (such as a water pump) is arranged in the water tank 30, which is used to accelerate the water flow through the pipeline to pump water into the spray assembly and the heat-triggered fire sprinkler 50. Specifically, the water inlet of the driving part is submerged in the water tank 30, and the water outlet of the driving part is connected to the water inlet of the main pipeline 60. The main pipeline 60 extends near the battery compartment 20, and the main pipeline 60 is divided into two routes by a three-way valve, wherein the first pipeline 70 is connected to the spray assembly, and the second pipeline 80 is connected to the heat-triggered fire sprinkler 50, such as Figure 2 , Figure 3 and 5 Under the action of the controller, the driving member drives the water in the water tank 30 to be transported to the sprinkler assembly through the main pipeline 60 and the first pipeline 70 , and then to the heat-triggered fire sprinkler 50 through the main pipeline 60 and the second pipeline 80 .

[0036] The spray assembly in the embodiment of the present invention includes a spray head 41 and a solenoid valve 42. The spray head 41 is disposed at the inner top of the battery compartment 20. Figure 6 and Figure 7 As shown, the spray head 41 is connected to the water outlet of the first pipeline 70. The solenoid valve 42 is arranged in the first pipeline 70. Figure 5As shown, the solenoid valve 42 is used to connect or disconnect the first pipeline 70. Specifically, the solenoid valve 42 is electrically connected to the controller, and the controller controls the opening and closing of the solenoid valve 42 based on the temperature information in the battery compartment 20. When the temperature information in the battery compartment 20 is higher than the warning temperature information, the controller controls the solenoid valve 42 to open, the sprinkler head 41, the first pipeline 70 and the main pipeline 60 are connected, and the water in the water tank 30 is transported to the sprinkler head 41 through the main pipeline 60 and the first pipeline 70, and sprays water into the battery compartment 20 to extinguish the fire. When the temperature information in the battery compartment 20 is higher than the trigger temperature of the heat-triggered fire sprinkler 50, the heat-triggered fire sprinkler 50 opens and sprays water into the battery compartment 20 to extinguish the fire.

[0037] The driving member in the embodiment of the present invention includes a water pump. The water pump is in a normally open state, and the controller controls the start and stop of the spray assembly by controlling the opening and closing of the solenoid valve; the heat-triggered fire sprinkler 50 can directly open the water path after the internal heat-sensitive element is triggered, and the heat-triggered fire sprinkler 50 can achieve fire extinguishing without other sensors.

[0038] The water fire fighting intelligent power exchange cabinet also includes a flow sensor, which is arranged in the main pipe 60 and is used to detect the water flow in the main pipe 60, to determine whether water is flowing and whether the water fire fighting system is started. Furthermore, the flow sensor is electrically connected to the controller, and the controller is used to obtain the flow information obtained by the flow sensor.

[0039] The power exchange cabinet body 10 includes a transparent portion 11, which is arranged corresponding to the water tank 30. The user can check the water level in the water tank 30 through the transparent portion 11. In order to facilitate the user to quickly confirm the amount of water in the water tank 30, a water level scale line 111 is provided on the transparent portion 11. Figure 1 In another embodiment, the outer wall of the water tank 30 is provided with a water level scale line 111. The transparent portion 11 is provided on the front wall of the power exchange cabinet body 10.

[0040] In the embodiment of the present invention, the rear wall surface of each battery compartment 20 is provided with a heat dissipation hole 22. Figure 2 and Figure 5 As shown, the rear wall of the power exchange cabinet body 10 is provided with a fire exhaust port 12, as shown in FIG. Figure 4 and Figure 5 As shown, in the event of a fire in the battery compartment 20, the fire can be ejected from the heat dissipation holes 22 behind the battery compartment 20 and outward through the fire outlet 12, thereby reducing safety hazards. Furthermore, there is a gap between the rear wall of the battery compartment 20 and the rear wall of the battery exchange cabinet body 10, forming an isolation space 17, such as Figure 5 As shown, the fire protection system will not be damaged in a short time after the fire occurs, and the safety is high.

[0041] The water fire fighting intelligent power exchange cabinet in the embodiment of the present invention further includes a first isolator 100 and a second isolator 110. The first isolator 100 and the second isolator 110 are arranged in the power exchange cabinet body 10 and are arranged at intervals along the height direction of the power exchange cabinet body 10. Figure 2 and Figure 3 As shown, the battery exchange cabinet body 10 is divided into a first accommodation chamber, a second accommodation chamber and a third accommodation chamber. The controller is installed in the first accommodation chamber, multiple battery compartments 20 are installed in the second accommodation chamber, and the water tank 30 is installed in the third accommodation chamber. The battery compartment 20 is isolated from the controller and the water tank 30 by the first isolation member 100 and the second isolation member 110. In the event of a fire, the fire can be prevented from spreading to the first accommodation chamber and the third accommodation chamber, ensuring the safety of other components.

[0042] Furthermore, independent heat dissipation ducts are respectively provided in the first accommodating chamber and the second accommodating chamber. A first air inlet 13 is provided on the front wall of the first accommodating chamber, and a first air outlet 15 is provided on the rear wall of the first accommodating chamber to dissipate heat for the components in the first accommodating chamber, and the heat dissipation efficiency is high. A first fan can be provided at the first air outlet 15, and when the temperature in the first accommodating chamber is high, the heat dissipation can be accelerated by the first fan. The first fan can be electrically connected to the controller, and the operating parameters of the first fan can be controlled based on the temperature information in the first accommodating chamber. A second air inlet 14 and a second air outlet 16 are provided on the rear wall of the second accommodating chamber, wherein the second air outlet 16 is provided below the second air inlet 14, to dissipate heat for the components in the second accommodating chamber. In order to improve the heat dissipation effect, a second fan is also provided in the second accommodating chamber, and the fan is provided at the second air outlet 16. Starting the second fan can improve the heat dissipation efficiency. The second fan can be connected to the controller, and the controller controls the operating parameters of the fan based on the temperature information in the second accommodating chamber. In the embodiment of the present invention, the number of the first air inlet 13, the first air outlet 15, the second air inlet 14 and the second air outlet 16 is not specifically limited and can be set according to actual conditions.

[0043] The power exchange cabinet body 10 is also provided with a cross beam 130 and a longitudinal beam 140. Figure 2 and Figure 3 As shown, the crossbeam 130 is used to support the battery compartment 20 and can also isolate the upper and lower rows of battery compartments 20. When a fire occurs in the battery compartment 20, it can prevent the fire from spreading to the adjacent battery compartment 20. The longitudinal beam 140 is used to strengthen the strength of the entire battery exchange cabinet body 10 and can also achieve the effect of isolation. The water return pipeline 90 in the embodiment of the present invention includes a transverse water return pipeline and a longitudinal water return pipeline, the transverse water return pipeline is connected to the longitudinal water return pipeline, and the longitudinal water return pipeline is connected to the water tank 30. In one embodiment, the transverse water return pipeline is arranged inside the cross beam 130, and the longitudinal water return pipeline is arranged inside the longitudinal beam 140, which can not only realize water return, but also in the event of a fire, the cross beam 130 can protect the transverse water return pipeline, and the longitudinal beam 140 can protect the longitudinal water return pipeline, thereby avoiding damage to the fire protection system, and having high safety.

[0044] The water fire fighting intelligent power exchange cabinet also includes a third isolator 120, which is arranged on the back of the battery compartment 20 and covers the return pipe 90 and the main pipe 60.
