Description

Technical Field

[0001] The utility model relates to the technical field of automobile fire fighting equipment, in particular to a high-pressure fine water mist control mechanism for automobile fire fighting. Background Art

[0002] New energy vehicles refer to vehicles that use unconventional vehicle fuels as their power source, or use conventional vehicle fuels and new vehicle-mounted power devices, and integrate advanced technologies in vehicle power control and driving to form vehicles with advanced technical principles, new technologies, and new structures. Electric vehicles are a type of new energy vehicle. Electric vehicles use lithium batteries as their power source. Due to overcharging of power batteries, internal and external short circuits, and other reasons, the safety hazards of vehicles during parking and charging are increased. In the event of a lithium battery fire, sufficient water is needed to extinguish it. At the same time, water must be sprayed under the vehicle to continuously cool down the batteries that have not burned. Using high-pressure fine water mist for fire extinguishing can have a good fire extinguishing effect; when using high-pressure fine water mist to extinguish fires, water is converted into extremely fine droplets, which quickly vaporize in the fire scene and absorb a large amount of heat, thereby reducing the temperature of the burning surface. At the same time, after the water mist vaporizes, its volume expands rapidly, and the formed water vapor surrounds the burning area, reducing the oxygen concentration and preventing the flame from being extinguished due to lack of oxygen. However, the control mechanism of the nozzle of the high-pressure fine water mist transports the nozzle to the lithium battery at the base of the vehicle body for cooling through a telescopic mechanism. The moving direction is limited, and the impact force is large when the nozzle is started, which may cause the nozzle to deviate from the position. Utility Model Content

[0028] It should be noted that by setting up a control component, the nozzle 6 can be moved at the bottom of the electric car, and the nozzle 6 can be moved to an area with high temperature to perform precise cooling. The control component and the nozzle 6 can be quickly fixed by the fixing plate 10 when the nozzle 6 sprays water mist, which facilitates the positioning and fixing of the nozzle 6 and prevents the position of the nozzle 6 from shifting. By setting up a double-headed motor 15, the control component can be driven forward and backward, and by setting up a transmission mechanism, the steering of the control component can be controlled. By setting up a cylinder 9, the fixing plate 10 can be driven to rise and fall, and by setting up a first sensor 11, the temperature of the bottom of the vehicle can be detected.

[0029] In this example, the first sensor 11 may be an infrared temperature sensor for measuring the temperature of the bottom of the vehicle.

[0030] In some embodiments, Figure 2 , Figure 3 , Figure 4 As shown, the transmission mechanism includes a support frame 17, a second motor 18, a first turntable 19 and two second turntables 20. The support frame 17 is fixedly installed on one side of the bottom end of the inner wall of the movable shell 12, the second motor 18 is fixedly installed on the top of the support frame 17, the output end of the second motor 18 extends to the inside of the support frame 17, the first turntable 19 is fixedly installed on the output end of the second motor 18, the first turntable 19 is located in the middle of the inner wall of the support frame 17, the two second turntables 20 are rotatably installed on the bottom end of the inner wall of the support frame 17, the bottom end of the second turntable 20 extends to the bottom end of the support frame 17, a connecting plate is fixedly installed on the bottom end of the second turntable 20, and a front wheel 22 is rotatably installed on one side of the connecting plate, the second turntables 20 are respectively located on both sides of the first turntable 19, and two transmission belts 21 are installed on the outer wall of the first turntable 19, and the other ends of the two transmission belts 21 are respectively installed on the outer walls of the two second turntables 20.

[0031] It should be noted that the second motor 18 can drive the first turntable 19 to rotate forward and reverse, and drive the second turntable 20 to rotate forward and reverse synchronously, thereby driving the front wheel 22 to turn and turn, and the double-headed motor 15 is started to drive the rear wheel 16 to rotate, so that the nozzle 6 moves forward and backward.

[0040] The high-pressure water pump and the water tank in the present invention are well-known components and will not be described in detail herein.

[0041] Working principle: When a car is put under fire, the control mechanism and the nozzle 6 are placed under the car, the first sensor 11 detects the temperature under the car, the second motor 18 is installed forward and reversely to drive the first turntable 19 to rotate forward and reverse, and drive the second turntable 20 to rotate forward and reverse synchronously, thereby driving the front wheel 22 to turn and steer, the double-headed motor 15 is started to drive the rear wheel 16 to rotate, so that the nozzle 6 moves forward and backward to move the nozzle 6. When the first sensor 11 detects a preset dangerous temperature value range, the movement of the nozzle 6 stops, and at the same time, the cylinder 9 is started to drive the fixed plate 10 to rise, the fixed plate 10 is pressed on the surface of the bottom of the car, and the bottom of the control component is pressed on the ground to fix the nozzle 6. The high-pressure water pump starts to deliver water, and the water is converted into water mist through the nozzle 6 and sprayed out to cool the bottom of the car.
