Detailed Description

The following examples are for illustrative purposes only and are not intended to limit the scope of the present invention.

Examples

Referring to fig. 1-2, an automatic positioning blowing fire extinguishing vehicle for a large mountain fire comprises a vehicle body 1, a protection plate 2 is fixed on the front side of the vehicle body 1, two sensing tubes 3 are symmetrically arranged on the protection plate 2, the sensing tubes 3 are metal round tubes with one closed side, a push rod 4 is hermetically and slidably connected in each sensing tube 3, the two push rods 4 are jointly and movably connected with a tire shaft, wheels are arranged at two ends of the tire shaft, one side of each push rod 4, which is close to the tire shaft, is rotatably connected with a slide block, an annular slide groove is arranged at the position of the tire shaft, which corresponds to the two slide blocks, the two slide blocks are respectively and slidably connected in the slide grooves at the corresponding positions, in the rotating process of the tire shaft, the slide block can still axially slide along the tire shaft, a second bevel gear 11 is fixedly connected to the tire shaft, and the second bevel gear 11 is connected with a power device, and a powerful fan 12 is fixed on the vehicle body 1.

The power device comprises a first bevel gear 10, the first bevel gear 10 is meshed with a second bevel gear 11, the first bevel gear 10 is rotationally connected to the vehicle body 1 through a bearing, the two push rods 4 are jointly rotationally connected with a telescopic loop bar 5, a horizontal synchronous groove 6 is arranged on the vehicle body 1, a synchronous rod 7 is interactively connected in the synchronous groove 6, the upper end of the synchronous rod 7 is connected with a driver 8, the driver 8 can be selected from an electric motor or an engine, the device can be powered, the output end of the driver 8 is connected with a clutch 9, the position of the clutch 9 relative to the vehicle body 1 is fixed, the output end of the clutch 9 is connected with a first bevel gear 10, namely, when the driver 8 is close to the clutch 9, the clutch 9 is in a separated state, and the driver 8 cannot drive the first bevel gear 10 to rotate when working; on the contrary, when the driver 8 is far away from the clutch 9, the clutch 9 is in a combined state, and the driver 8 works to drive the first bevel gear 10 to rotate, so as to drive the tire shaft to rotate to drive the vehicle body 1 to move.

One side of the synchronizing rod 7 abuts against the telescopic loop bar 5, the other end of the telescopic loop bar 5 is fixedly provided with a tensioning spring, and the tensioning spring is fixed in the inner wall of the synchronizing groove 6 to ensure that the synchronizing rod 7 abuts against the telescopic loop bar 5.

In the invention, when a mountain fire occurs, the device is placed at a fire scene, the driver 8 is started, the temperature of the sensing tube 3 is lower in an initial state, the air pressure in the sensing tube is also lower, the motion amount of the push rod 4 relative to the sensing tube 3 is smaller at the moment, the clutch 9 is in a combined state, the power of the driver 8 is transmitted to the second bevel gear 11 through the clutch and the first bevel gear 10, the tire shaft is driven to rotate, so that the vehicle body 1 advances to be close to a fire source, the powerful fan 12 above the vehicle body 1 works to blow a large amount of cold air into a combustion object of the fire source, and the effects are two: 1, blowing away the comburent, and 2, reducing the temperature of the comburent, and finally realizing the effect of fire extinguishing.

When the vehicle body 1 is close to a fire source, the temperature of the environment where the vehicle body 1 is located can be obviously increased, at the moment, the air pressure in the sensing tube 3 is increased to push the push rods 4 to move, the two push rods 4 drive the telescopic sleeve rod 5 to move to enable the synchronous rod 7 and the driver 8 to move towards the clutch 9, the clutch 9 is gradually separated, the moving speed of the vehicle body 1 is gradually reduced until the vehicle stops moving forwards, and the powerful fan 12 can be aligned to the fire source to extinguish fire; when the fire source is positioned in front of the side of the vehicle body 1, the temperatures of the two sensing tubes 3 are different inevitably, the temperature of the closer side is obviously higher than that of the other side, the movement amount of the push rod 4 of the closer side is obviously larger than that of the other side, and the telescopic loop rod 5 deflects and extends, so that the tire shaft deflects to realize the steering of the vehicle body 1, and further the device provided by the invention can automatically steer and move to the lateral fire source until the fire extinguishing is finished.

Although the terms vehicle body 1, shield 2, susceptor tube 3, push rod 4, telescoping loop bar 5, synchronization slot 6, synchronization rod 7, driver 8, clutch 9, first bevel gear 10, second bevel gear 11, power fan 12, etc. are used more herein, the possibility of using other terms is not excluded.
