Description

Technical Field

[0001] The invention relates to the technical field of prefabricated cabins, and in particular to a liquid-cooled battery prefabricated cabin which is easy to carry. Background Art

[0002] The prefabricated battery cabin is an integrated energy storage system in which multiple systems are integrated into a prefabricated cabin for rapid deployment and maintenance.

[0003] Most of the existing fire extinguishing methods for battery prefabricated cabins use spray fire extinguishing.

DETAILED DESCRIPTION

[0033] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments.

[0034] In one embodiment, Figure 1-Figure 10 As shown, a liquid-cooled battery prefabricated cabin that is easy to carry includes a prefabricated cabin body 1, a circulating liquid cooling component 4, a sand covering component 5, a rotary spray component 6, and a sealing component 7. A box frame 3 is arranged inside the prefabricated cabin body 1, and a plurality of battery storage boxes 9 are arranged on the box frame 3. A battery body 31 is fixed in the battery storage box 9 by bolts. The circulating liquid cooling component 4 includes a condenser 8 and a circulating pump 10. A condenser 8 is arranged through the side of the box frame 3. The side wall of the box frame 3 is fixedly connected with the circulating pump 10 through a bracket. The circulating pump 10 is connected to the condenser 8. The condenser 8 is arranged above the battery storage box 9. A heat exchanger 11 is fixed to the side wall of the box frame 3 by bolts. The heat exchanger 11 is connected to the condenser 8. The battery storage box 9 is provided with a revolving door 37 by rotating through a hinge. A sealing strip is arranged between the revolving door 37 and the battery storage box 9. Two heat dissipation holes are provided on the top wall of the battery storage box 9, and the condenser 8 is provided with a water inlet.

[0035] The sand covering assembly 5 is arranged at the top wall of the battery storage box 9 to prevent the battery body 31 from contacting with oxygen;

[0036] The rotating spray assembly 6 is arranged at the top wall of the battery storage box 9 to improve the spraying range and the fire extinguishing effect;

[0037] The sealing assembly 7 is arranged at the top wall of the battery storage box 9 to form a closed space in the battery storage box 9 .

[0038] The circulating pump 10 is driven to drive the coolant in the condenser 8 to circulate, absorb the heat around the battery storage box 9, and reduce the temperature around the battery storage box 9, thereby achieving the purpose of cooling the battery body 31.

[0039] The battery storage box 9 and the revolving door 37 are both made of fireproof materials.

[0040] In one embodiment, Figure 6 and Figure 7 As shown, the rotary spray assembly 6 includes a rotating tube 15 and a turntable 25. The top wall of the battery storage box 9 is connected to the rotating tube 15 through a bearing. A plurality of connecting tubes 14 are arranged on the side wall of the condensing tube 8. The connecting tubes 14 are connected to the rotating tube 15 through a bearing. The connecting tubes 14 are provided with a second electrically-controlled valve 13. The condensing tube 8 is provided with a plurality of first electrically-controlled valves 12. A rotating blade 32 is arranged on the inner wall of the rotating tube 15. The bottom wall of the rotating tube 15 is fixedly connected to the turntable 25. The turntable 25 is connected to four circumferentially distributed spray cylinders 26 through bearings. The top wall of the spray cylinder 26 is connected to a rotating cylinder 36 through a bearing. A water pipe 29 is fixedly connected between the rotating cylinder 36 and the rotating tube 15. A gear 30 is arranged on the peripheral side of the spray cylinder 26. The inner top wall of the battery storage box 9 is fixedly connected to a gear ring 28 through a bracket. The gear ring 28 meshes with the gear 30. A spray head is arranged on the bottom wall of the spray cylinder 26.

[0041] When the battery body 31 is damaged and burns, the smoke generated by the combustion will trigger the smoke sensor 35, and the smoke sensor 35 will transmit the signal to the controller. The controller closes the first electrically controlled valve 12 closest to the burning position and opens the second electrically controlled valve 13 closest to the burning position. At this time, the coolant flows into the rotating tube 15 under the action of the circulating pump 10. Since the rotating tube 15 is provided with rotating blades 32, the rotating tube 15 rotates under the action of the high-speed water flow, and the coolant enters the spray barrel 26 through the water pipe 29. The rotation of the rotating tube 15 drives the turntable 25 to rotate, and the turntable 25 drives the spray barrel 26 to revolve. When the spray barrel 26 revolves, the gear 30 cooperates with the gear ring 28 to drive the spray barrel 26 to rotate, so that the coolant is evenly and comprehensively sprayed above the battery body 31, and the battery body 31 is extinguished, thereby improving the fire extinguishing efficiency.

[0042] In one embodiment, Figure 6 , Figure 7 , Fig. 9 As shown, the sand covering assembly 5 includes a mounting rail 23 and a slider 24. Two symmetrical mounting rails 23 are arranged on the inner top wall of the battery storage box 9. The mounting rails 23 are slidably connected to the slider 24. A latex sandbag 22 is arranged on the lower surface of the slider 24. There is a pre-tightening force between the slider 24 and the mounting rail 23. Four circumferentially evenly distributed cutting plate grooves are opened on the circumference of the turntable 25. The inner side wall of the cutting plate groove is rotatably connected to the cutting plate 27 through a pin shaft. A coil spring 34 is arranged between the cutting plate 27 and the inner side wall of the cutting plate groove.

[0043] As the turntable 25 rotates faster and faster, the cutting plate 27 flips outward under the action of centrifugal force. When the sharp part of the cutting plate 27 contacts the latex sandbag 22, the latex sandbag 22 is scratched, and the sand in the latex sandbag 22 leaks down and directly covers the surface of the battery body 31, which can effectively reduce the fire and improve the fire extinguishing efficiency.

[0044] In one embodiment, Figure 4 As shown, the closing component 7 includes an insert block 17 and a closing plate 18, a closing plate groove is provided on the inner wall of the heat dissipation hole, the closing plate 18 is slidably connected to the inner wall of the closing plate groove, a spring 33 is fixedly connected between the closing plate 18 and the inner wall of the closing plate groove, a magnetic plate 16 is fixedly connected to the peripheral side of the rotating tube 15, four insert block holes opposite to each other are provided on the top wall of the battery storage box 9, two snap-in grooves 20 are provided on the side wall of the closing plate 18, an insert block 17 is slidably connected to the inner wall of the insert block hole, the insert block 17 is slidably connected to the snap-in groove 20, and a magnetic block 19 is fixedly connected to the upper surface of the insert block 17.

[0045] The rotating tube 15 rotates while driving the magnetic plate 16 to rotate. When the magnetic plate 16 passes over the plug block 17 during its rotation, the magnetic block 19 is adsorbed under the magnetic plate 16, causing the plug block 17 to leave the card slot 20. At this time, the closing plate 18 blocks the heat dissipation holes under the action of the spring 33, so that the battery storage box 9 forms a closed environment, isolating the outside oxygen from entering the battery storage box 9, and after the oxygen in the battery storage box 9 is burned out, the fire is automatically extinguished, thereby improving the fire extinguishing effect.

[0046] In one embodiment, Figure 4 and Figure 8 As shown, a pull plate 21 is fixedly connected to the side wall of the closing plate 18 .

[0047] It is convenient for people to manually pull the pull plate 21 to reset the closing plate 18.

[0048] In one embodiment, Figure 5 As shown, a smoke sensor 35 is provided on the inner wall of the battery storage box 9, the smoke sensor 35 is electrically connected to the controller, and the first electrically controlled valve 12 and the second electrically controlled valve 13 are electrically connected to the controller.

[0049] When the battery body 31 is damaged and burns, the smoke generated by the burning will trigger the smoke sensor 35, and the smoke sensor 35 will transmit a signal to the controller, and the controller will close the first electrically controlled valve 12 closest to the burning position and open the second electrically controlled valve 13 closest to the burning position.

[0050] In one embodiment, Figure 1 As shown, the side wall of the prefabricated cabin body 1 is provided with four suspension rods 2 which are opposite to each other.

[0051] The prefabricated cabin body 1 is conveniently transported by means of a lifting device.

[0052] The above embodiment discloses a liquid-cooled battery prefabricated cabin that is easy to carry, and its specific working principle and process are as follows:

[0053] S1; start the circulation pump 10, the circulation pump 10 drives the coolant in the condenser 8 to circulate, absorb the heat around the battery storage box 9, and reduce the temperature around the battery storage box 9, so as to achieve the purpose of cooling the battery body 31;

[0054] S2: When the battery body 31 is damaged and burns, the smoke generated by the combustion will trigger the smoke sensor 35. The smoke sensor 35 transmits a signal to the controller. The controller closes the first electrically controlled valve 12 closest to the burning position and opens the second electrically controlled valve 13 closest to the burning position. At this time, the coolant flows into the rotating tube 15 under the action of the circulating pump 10. Since the rotating blades 32 are arranged in the rotating tube 15, the rotating tube 15 rotates under the action of the high-speed water flow, and the coolant enters the spray barrel 26 through the water pipe 29. The rotation of the rotating tube 15 drives the turntable 25 to rotate, and the turntable 25 drives the spray barrel 26 to revolve. When the spray barrel 26 revolves, the gear 30 cooperates with the gear ring 28 to drive the spray barrel 26 to rotate, so that the coolant is evenly and comprehensively sprayed on the battery body 31, and the battery body 31 is extinguished, thereby improving the fire extinguishing efficiency.

[0055] S3: The rotating tube 15 rotates while driving the magnetic plate 16 to rotate. When the magnetic plate 16 passes over the plug block 17 during its rotation, the magnetic block 19 is adsorbed under the magnetic plate 16, so that the plug block 17 leaves the clamping groove 20. At this time, the closing plate 18 blocks the heat dissipation hole under the action of the spring 33, so that the battery storage box 9 forms a closed environment, isolating the external oxygen from entering the battery storage box 9, and after the oxygen in the battery storage box 9 is burned out, the fire is automatically extinguished, thereby improving the fire extinguishing effect;

[0056] S4: As the speed of the turntable 25 rotates faster and faster, the cutting plate 27 flips outward under the action of centrifugal force. When the sharp part of the cutting plate 27 contacts the latex sandbag 22, the latex sandbag 22 is scratched, and the sand in the latex sandbag 22 leaks down and directly covers the surface of the battery body 31, which can effectively reduce the fire and improve the fire extinguishing efficiency.

[0057] The above is only a specific implementation of the present application, but the protection scope of the present application is not limited thereto. Any person skilled in the art who is familiar with the present technical field can easily think of changes or substitutions within the technical scope disclosed in the present application, which should be included in the protection scope of the present application. Therefore, the protection scope of the present application should be based on the protection scope of the claims.
