[0034] Example 1

[0035] The embodiment of the present invention provides a self-starting safety protection device for a mobile charging vehicle, such as Figure 1-Figure 11 As shown, it includes: a charging vehicle chassis 1 and a fire extinguishing component, a carriage 2 is arranged on the charging vehicle chassis 1, a plurality of explosion-proof boxes 3 are arranged in the carriage 2, telescopic components 4 are arranged on the inner walls of the explosion-proof boxes 3, a pressure plate 5 is arranged at the output end of the telescopic component 4, a power supply battery 6 is arranged between the six pressure plates 5, a plurality of fire extinguishing hoods 7 are arranged on the side of the pressure plate 5 close to the power supply battery 6, a fire monitoring component and a fire extinguishing component are arranged in the fire extinguishing hood 7, the fire monitoring component is used to monitor the power supply battery 6, and the fire extinguishing component is used to extinguish the fire of the power supply battery 6, a controller and an external power supply are arranged outside the carriage 2, and the controller is electrically connected to the telescopic component 4, the fire monitoring component and the external power supply respectively.

[0036] The working principle and beneficial effects of the above technical solution are as follows: a carriage 2 is arranged on the chassis 1 of the charging vehicle, and a plurality of explosion-proof boxes 3 are arranged from top to bottom in the carriage 2, an installation port is arranged on the front side of the explosion-proof box 3, and a cover plate is arranged at the installation port. After the cover plate is removed, the power supply battery 6 can be installed from the installation port, and a telescopic component 4 is arranged on the inner wall of the explosion-proof box 3, and the telescopic component 4 is an electric push rod. A pressure plate 5 is arranged at one end of the telescopic component 4 close to the power supply battery 6, and a plurality of fire extinguishing hoods 7 are arranged on the side of the pressure plate 5 close to the power supply battery 6. A fire monitoring component and a fire extinguishing component are arranged in the fire extinguishing hood 7, and the fire monitoring component is used to monitor the status of the power supply battery 6. The fire monitoring component includes at least one of a temperature sensor and a smoke sensor. The temperature sensor can collect the regional temperature outside the power supply battery 6, and the smoke sensor is used to collect the smoke concentration information in the region, and judge whether the power supply battery 6 is on fire through the controller. When the monitoring value of the temperature sensor or the smoke sensor is greater than the corresponding preset value, the controller judges that the corresponding area of ​​the power supply battery 6 is on fire, and different fire extinguishing hoods The fire monitoring components in 7 monitor different areas, and multiple fire extinguishing hoods 7 are distributed above and below, left and right, and front and back of the power supply battery 6. When the fire monitoring component on one side detects that the power supply battery 6 is on fire, the controller controls the corresponding telescopic component 4 to extend, thereby pushing the pressure plate 5 to move toward the power supply battery 6, so that the fire extinguishing hood 7 is set at the fire position, and then the fire extinguishing component is automatically started, and the fire position can be extinguished to achieve automatic fire extinguishing, prevent the occurrence of large-scale fires, reduce damage to the power supply battery 6, and improve the safety and reliability of the power supply battery 6. The fire extinguishing hood 7 covers the fire position, which can isolate external gas and prevent the fire from further expanding, protecting the power supply battery 6 at different positions, and further reducing damage to the power supply battery 6. The external power supply is set outside the car 2. The external power supply can power the controller, telescopic component 4, and fire monitoring component, and is not affected by the internal environment of the car 2. It is not easy to cause power failure due to internal fire, which ensures the normal development of fire extinguishing work and improves safety.

[0037] Example 2

[0038] On the basis of the above-mentioned embodiment 1, Figure 1-Figure 5 As shown, a plurality of fire extinguishing covers 7 are arranged at equal intervals along the length direction of the pressing plate 5;

[0039] The power supply battery 6 is installed in the explosion-proof box 3 through an installation component, and the installation component includes a mounting frame 8. The outer wall of the mounting frame 8 is connected to the inner wall of the explosion-proof box 3 through a plurality of fixing columns 9. An opening is set on the front side of the mounting frame 8, and the power supply battery 6 is installed in the mounting frame 8 through the opening. A plurality of ventilation holes 10 are set on the other side walls of the mounting frame 8. The ventilation holes 10 correspond to the fire extinguishing hood 7 one by one, and the inner wall of the ventilation hole 10 is adapted to the outer wall of the fire extinguishing hood 7.

[0040] The working principle and beneficial effects of the above technical solution are as follows: the power supply battery 6 is installed in the installation frame 8, and the installation frame 8 is connected to the inner wall of the explosion-proof box 3 through the fixing column 9. The installation frame 8 can keep the power supply battery 6 in the center position of the explosion-proof box 3, and the side walls of the installation frame 8 are provided with ventilation holes 10. The ventilation holes 10 can accelerate the heat dissipation of the power supply battery 6, avoid the power supply battery 6 from being overheated, and further improve the safety of the power supply battery 6. The ventilation holes 10 correspond to the fire extinguishing hood 7. When a certain part of the power supply battery 6 catches fire, the corresponding pressure plate 5 approaches the power supply battery 6, so that the fire extinguishing hood 7 passes through the ventilation holes 10 and is set at the fire position of the power supply battery 6, and the fire is accurately extinguished at the fire position, thereby achieving the purpose of automatic fire extinguishing.

[0041] Example 3

[0042] On the basis of Example 1 or 2, Fig.11 As shown, an annular sealing groove 11 is provided on the end surface of the fire extinguishing hood 7 close to one end of the power supply battery 6 , and a sealing ring 12 is provided in the annular sealing groove 11 .

[0043] The working principle and beneficial effects of the above technical solution are as follows: a sealing ring 12 is arranged on the end face of the fire extinguishing hood 7. When the fire extinguishing hood 7 is arranged outside the power supply battery 6, the sealing ring 12 fits tightly with the outer wall of the power supply battery 6, which can improve the sealing performance of the fire extinguishing hood 7, thereby isolating external gas and improving the fire extinguishing effect. The sealing ring 12 is made of high temperature resistant fireproof material, which can isolate the flame at the fire location and avoid the rapid expansion of the fire range.

[0044] Example 4

[0045] On the basis of any one of Examples 1-3, Figure 4-Figure 11 As shown, the fire extinguishing assembly includes a fire extinguishing pipe 13, which is arranged in the fire extinguishing cover 7, and a plurality of high-pressure nozzles 14 are connected to the fire extinguishing pipe 13, and the output end of the high-pressure nozzle 14 faces the power supply battery 6;

[0046] The fire extinguishing assembly also includes a liquid supply mechanism, which includes a storage tank 15. The storage tank 15 is arranged outside the carriage 2. The fire extinguishing agent is stored in the storage tank 15. The output end of the storage tank 15 is connected to the first diversion pipe 17 through the output pipe 16. A plurality of first connecting pipes 18 are arranged on the first diversion pipe 17. The first connecting pipe 18 is connected to an end of the second diversion pipe 19 away from the end of the first diversion pipe 17. The second diversion pipe 19 is arranged on the outer wall of the pressure plate 5. A plurality of second connecting pipes 20 are arranged on the second diversion pipe 19. The second connecting pipe 20 extends to the inside of the fire extinguishing hood 7 away from the end of the second diversion pipe 19 and is connected to the fire extinguishing pipe 13.

[0047] The working principle and beneficial effects of the above technical solution are as follows: the fire extinguishing agent is stored in the storage tank 15. When the fire extinguishing cover 7 is set outside the power supply battery 6, the fire extinguishing agent in the storage tank 15 flows into the first shunt pipe 17 through the output pipe 16, is distributed to multiple first connecting pipes 18 through the first shunt pipe 17, and then is transmitted to the second shunt pipes 19 in different explosion-proof boxes 3 through the first connecting pipe 18. The fire extinguishing agent flows into the fire extinguishing pipeline 13 through the second connecting pipe 20 and is sprayed out through the high-pressure nozzle 14. The fire extinguishing agent can be sprayed to the fire position of the power supply battery 6, reaching The fire extinguishing hood 7 can achieve the effect of rapid fire extinguishing, and since the fire extinguishing hood 7 is provided, the sealing hood of the fire extinguishing hood 7 is provided outside the fire position of the power supply battery 6, the fire extinguishing agent can concentrate on the fire position to extinguish the fire, and a large amount of fire extinguishing agent is not required, so there is no need to carry a large amount of fire extinguishing agent, which further reduces the overall weight of the mobile charging vehicle and reduces energy consumption. On the other hand, the fire extinguishing agent sprayed by the high-pressure nozzle 14 can be accumulated in the fire extinguishing hood 7, reducing the loss of the fire extinguishing agent. The fire extinguishing agent accumulated in the fire extinguishing hood 7 gradually increases, which can quickly extinguish the flame, enhance the fire extinguishing effect, and improve the fire extinguishing efficiency.

[0048] Example 5

[0049] On the basis of Example 4, Figure 1-Figure 3 As shown, a water pump 21 is provided on the output pipe 16 , and the water pump 21 is electrically connected to the controller.

[0050] The working principle and beneficial effects of the above technical solution are as follows: when the fire monitoring component detects that a certain area of ​​the power supply battery 6 is on fire, the controller first controls the movement of the pressure plate 5 through the telescopic component 4, so that the fire extinguishing hood 7 is set in the fire area, and then the controller controls the water pump 21 to start, which can increase the output pressure of the fire extinguishing agent, so that the fire extinguishing agent is quickly sprayed out from the high-pressure nozzle 14, further improving the fire extinguishing efficiency.

[0051] Example 6

[0052] On the basis of Example 4 or 5, Figure 6-Figure 8 As shown, a driving pipe 22 is arranged on the second connecting pipe 20, the driving pipe 22 is located inside the fire extinguishing hood 7, the driving pipe 22 is perpendicular to the second connecting pipe 20, one end of the driving pipe 22 is communicated with the inside of the second connecting pipe 20, and the other end of the driving pipe 22 is communicated with the inside of the fire extinguishing hood 7, a blocking component is arranged in the second connecting pipe 20, and a driving component is arranged in the driving pipe 22;

[0053] The blocking assembly includes a fixed block 23, both ends of which are connected to the inner wall of the second connecting tube 20 respectively, and blocking plates 24 are symmetrically arranged on the upper and lower sides of the fixed block 23, one end of the blocking plate 24 is hingedly connected to the fixed block 23, and the other end of the blocking plate 24 contacts the inner wall of the second connecting tube 20, a fixed rod 25 is arranged on one side of the fixed block 23, and the fixed block 23 and the blocking plate 24 are connected by a connecting spring 26, a sliding block 27 is arranged at one end of the fixed rod 25 away from the fixed block 23, and the sliding block 27 is slidably arranged in a moving tube 28, and the sliding block 27 is connected to the inner wall of the moving tube 28 through a compression spring, and sliding plates 29 are symmetrically arranged on the upper and lower sides of the moving tube 28, and the sliding plate 29 is slidably connected to the inner wall of the second connecting tube 20, and the end of the sliding plate 29 away from the moving tube 28 contacts the blocking plate 24;

[0054] The driving assembly includes a sealing block 30, the outer wall of the sealing block 30 is slidably connected to the inner wall of the driving tube 22 up and down, a driving column 31 is arranged on the side of the sealing block 30 close to the second connecting tube 20, a reset hole 32 is arranged in the center of the driving column 31, a guide column 33 is slidably arranged in the reset hole 32, one end of the guide column 33 extends to the outside of the reset hole 32 and is connected to the inner wall of the second connecting tube 20, the guide column 33 is connected to the inner wall of the reset hole 32 through a reset spring 34, a driving groove 35 is arranged on the outer wall close to the lower end of the driving column 31, the driving groove 35 is located on the side of the driving column 31 close to the moving tube 28, the cross-section of the driving groove 35 is a right triangle, the depth of the driving groove 35 close to the sealing block 30 is greater than the depth of the driving groove 35 away from the sealing block 30, the end of the moving tube 28 away from the fixed block 23 is set to a hemispherical shape, and the end of the moving tube 28 away from the fixed block 23 contacts the inner wall of the driving groove 35.

[0055] The working principle and beneficial effects of the above technical solution are as follows: when the power supply battery 6 is not on fire, the blocking component is used to block the second connecting pipe 20 to prevent the fire extinguishing agent from flowing into the fire extinguishing pipe 13. When the power supply battery 6 is on fire, the driving component can control the blocking component to work so that the second connecting pipe 20 is connected to the fire extinguishing pipe 13, and the fire extinguishing agent can flow into the fire extinguishing pipe 13 through the second connecting pipe 20 and be sprayed out from the high-pressure nozzle 14. Specifically, when the power supply battery 6 is on fire, the fire extinguishing hood 7 is arranged in the fire area. Since the fire will generate a large amount of harmful gas, the internal pressure of the fire extinguishing hood 7 will increase, and the harmful gas can push the sealing block 30 to slide on the inner wall of the driving pipe 22. The sealing block 30 drives the driving column 31 to move into the second connecting pipe 20, and the guide column 33 slides in the reset hole 32. The reset spring 34 is compressed. At the same time, under the action of the compression spring, as the position of the driving groove 35 changes, the moving tube 28 can slide along the inner wall of the driving groove 35, and the moving tube 28 gradually moves away from the fixed block 23. The moving tube 28 drives the sliding The plate 29 slides in a direction away from the fixed block 23, and under the action of the connecting spring 26, the blocking plate 24 swings toward the driving column 31, so that the inside of the second connecting pipe 20 enters a connected state from a blocked state, and the fire extinguishing agent can flow into the fire extinguishing pipe 13 through the second connecting pipe 20, and finally quickly sprayed from the high-pressure nozzle 14 to the ignition position of the power supply battery 6 to achieve rapid fire extinguishing. Through the driving component, the blocking component can be driven without the help of external power, and is not subject to external interference, thereby ensuring the normal progress of the fire extinguishing work. Moreover, since the harmful gas at the ignition position expands rapidly, even if no flame is detected, the driving component can be automatically and quickly triggered, thereby improving the fire extinguishing efficiency. There will be no expanding gas inside the fire extinguishing cover 7 at the unignited position, so the high-pressure nozzle 14 at the unignited position will not spray out the fire extinguishing agent, thereby avoiding the waste of the fire extinguishing agent, and enabling the limited fire extinguishing agent to be concentratedly sprayed to the ignition position, thereby achieving the purpose of automatic fire extinguishing, thereby improving the fire extinguishing effect at the ignition position, helping to quickly extinguish the flame, and improving the safety and reliability of the mobile charging vehicle.
