[0051] On the other hand, combined Figure 8 The present application proposes a fire extinguishing control system, which is applied to the above-mentioned fire extinguishing auxiliary device. The spray end of the fire extinguisher 5 is fixedly connected with a sensing mounting sleeve 51. The four sides of the sensing mounting sleeve 51 are all arc-shaped, so that the four sides of the sensing mounting sleeve 51 maintain independent smoke sensing areas. Smoke sensors A, smoke sensor B, smoke sensor C, and smoke sensor D are respectively installed on the front, back, left and right of the sensing mounting sleeve 51; the bottom end of the sensing mounting sleeve 51 is connected with a sensing mounting ring 52, and the bottom end of the sensing mounting ring 52 is installed with a smoke sensor E; the spray end of the fire extinguisher 5 is installed with a solenoid valve.

[0052] Among them, the outer end of the sensing mounting ring 52 protrudes from the outer end of the sensing mounting sleeve 51, so that the smoke sensor E has an independent smoke sensing area, and the inner diameter of the bottom end of the guide cover 44 is larger than the outer diameter of the sensing mounting ring 52, and the guide cover 44 can be covered on the outside of the sensing mounting ring 52.

[0053] Specifically, it also includes a controller, and the output ends of smoke sensor A, smoke sensor B, smoke sensor C, smoke sensor D and smoke sensor E are connected to the input end of the controller, and the output end of the controller is connected to the input ends of the first cylinder 69 and the second cylinder 610, and the output end of the controller is also electrically connected to the solenoid valve.

[0054] The working principle of this embodiment is: the device is installed on the top of the battery car shed with the fire extinguisher 5 facing downward. When a fire occurs accidentally during charging of the battery car, smoke will be generated during the fire. A smoke sensor 11 is arranged at the injection end of the fire extinguisher 5. The smoke sensor 11 includes a smoke sensor A, a smoke sensor B, a smoke sensor C, a smoke sensor D, and a smoke sensor E. The smoke sensor A, the smoke sensor B, the smoke sensor C, and the smoke sensor D are respectively arranged at the front, rear, left, and right of the induction mounting sleeve 51, and the smoke sensor E is arranged at the bottom of the induction mounting ring 52. When the fire occurs at the bottom of the fire extinguisher 5, the smoke sensor E will be sensed at the first time. At this time, the smoke sensor will send an electrical signal to the controller. The controller controls the solenoid valve to open, and directly sprays dry powder vertically downward to extinguish the fire, thereby completing the fire extinguishing efficiently and quickly.

[0055] When the fire point is in other directions, for example, the fire point is at the lower right side of the fire extinguisher 5, the smoke sensor D will sense the smoke at the first time, and the smoke sensor D will send a signal to the controller, which will start the second cylinder 610 to extend the telescopic end of the second cylinder 610, so that the corresponding rack 64 and gear 65 are meshed and driven, driving one of the rotating shafts 61 to rotate one circle (the rotating shaft 61 in the left and right directions), so that the coil on the left side wall of the rotating shaft 61 is released and the coil on the right side is retracted, and then the spraying direction of the fire extinguisher 5 is adjusted by the change of the state of the left and right steering traction ropes 66, so that the spraying direction of the fire extinguisher 5 is adjusted. end toward the lower right; when the fire point is at the lower left, the smoke sensor C senses the smoke at the first time, and the smoke sensor C will send a signal to the controller, which will start the second cylinder 610 to retract the telescopic end of the second cylinder 610, so that the corresponding rack 64 and gear 65 are reversely meshed and transmitted, driving one of the rotating shafts 61 to rotate one circle in the opposite direction (the rotating shaft 61 in the left and right directions), so that the coil on the left side wall of the rotating shaft 61 is retracted and the coil on the right side is released, and then the spraying direction of the fire extinguisher 5 is adjusted by changing the states of the left and right steering traction ropes 66, so that the spraying end of the fire extinguisher 5 is facing the lower left. When the fire point is at the front and lower part of the fire extinguisher 5, the smoke sensor A will sense the smoke at the first time, and the smoke sensor A will send a signal to the controller, which will start the first cylinder 69, so that the telescopic end of the first cylinder 69 extends out, so that the corresponding rack 64 and the gear 65 are meshed and driven, and one of the rotating shafts 61 rotates one circle (the rotating shaft 61 in the front and rear directions), so that the coil in front of the side wall of the rotating shaft 61 is retracted and the coil in the rear is released, and then the spraying direction of the fire extinguisher 5 is adjusted by the change of the state of the front and rear two steering traction ropes 66, so that the spraying end of the fire extinguisher 5 faces the front and lower part; when the fire point is at the rear and lower part of the fire extinguisher 5, the smoke sensor A will send a signal to the controller, and the first cylinder 69 will be started by the controller ... Sensor B senses smoke for the first time, and smoke sensor B will send a signal to the controller, which will start the first cylinder 69 through the controller, so that the telescopic end of the first cylinder 69 will retract, so that the corresponding rack 64 and gear 65 will mesh and drive in the opposite direction, driving one of the rotating shafts 61 to rotate in the opposite direction (the rotating shaft 61 in the front and rear directions), so that the coil in front of the side wall of the rotating shaft 61 is released and the coil in the back is retracted, and then the spray direction of the fire extinguisher 5 is adjusted by the change of the state of the front and rear two steering traction ropes 66, so that the spray end of the fire extinguisher 5 is facing the rear and lower, so as to accurately control the spray direction of the fire extinguisher 5 according to the direction of the fire, and ensure the efficiency of fire extinguishing. It should be noted that when one of the smoke sensors senses smoke, the controller will start the cylinder and then open the solenoid valve to complete the spray of dry powder in time. It should be noted that the upper end of the connecting rod 7 is fixedly connected to a limit contact circle. When the steering ball 9 turns to either side under the control of the steering control mechanism 6, the limit contact circle will contact the lower end of the support column 8, thereby positioning the fire extinguisher 5 after it turns, and it will not shake randomly under the injection pressure.

[0056] In the present application, a guide cover member 4 is arranged on the side wall of the fire extinguisher 5 and a pneumatic pressing member 10 is arranged inside the control slot 2. When the steering control mechanism 6 is in operation, the guide cover member 4 can be driven by the pneumatic pressing member 10. Specifically, when one of the rotating shafts 61 rotates (forward or reverse), it will drive one of the pair of push rods 103 to rotate. When the push rod 103 rotates downward, it will contact and squeeze one of the pair of cross plates 102, causing the transmission plate 101 to move downward. The downward movement of the two transmission plates 101 will push the piston ring 46 to move toward the inside of the annular piston cylinder 45, and squeeze the gas inside the annular piston cylinder 45 into the pneumatic hood 41 through a plurality of air pipes 42. Under the action of air pressure, the pneumatic ring 43 will move downward, and the downward movement of the pneumatic ring 43 will drive the guide hood 44 to move downward. The hood is arranged on the outside of the output end of the fire extinguisher 5, and can play a guiding role when the dry powder is sprayed at an angle to either side, so that the fire extinguisher 5 can fully spray to the fire point when it is tilted for fire extinguishing, thereby ensuring the fire extinguishing effect, avoiding excessive expansion of the range of dry powder during tilted spraying and wasting dry powder, and also avoiding excessive impact on the visibility of the nearby environment.

Based on the technical solutions of the present application and the relevant inspirations of the above-mentioned embodiments, those skilled in the art may make various alternative improvements and combinations to the above-mentioned specific embodiments. The above-mentioned specific embodiments are merely explanations of the present application, and they are not limitations of the present application.
