[0020] The multifunctional wind-water fire-fighting vehicle includes a remote controller for controlling the movement of the chassis, the operation of the fan, the horizontal swing of the fan, the up and down swing of the fire extinguisher, and the action of the obstacle removal unit.
[0021] The beneficial effects of this patent are:
[0022] The fan generates a high-speed airflow, which passes through the fire extinguisher and is directly sprayed to the root of the fire source to cool down the fire source, thereby achieving the effect of extinguishing the fire. The horizontal swing device can drive the fan as a whole, the fire extinguisher, the up and down swing device, etc. to swing horizontally, so as to horizontally sweep the fire source. The up and down swing device can drive the fire extinguisher to swing up and down relative to the fan outlet pipe, so as to sweep the fire source up and down. The chassis can walk, and a crawler chassis belonging to the prior art is preferably selected, which can adapt to rugged ground environments such as mountains and woodlands. The chassis drives the fan as a whole to move near the fire source, so that the high-speed airflow directly sprays the root of the fire source, rapidly cools the root of the fire source, and achieves fire extinguishing.
[0023] The fire extinguisher is composed of two layers of inner and outer casings (outer tube and inner tube), and the inner tube can be extended by using a telescopic push rod, so that the front air outlet of the fire extinguisher (inner tube) is closer to the root of the fire source, further improving the fire extinguishing effect.
[0024] The fire extinguishing agent in the fire extinguishing agent box is delivered to the nozzle by a liquid pump through the fire extinguishing agent delivery pipe. The nozzle is located at the front air outlet of the fire extinguisher (inner tube). The fire extinguishing agent sprayed from the nozzle is atomized by the high-speed airflow and sprayed to the fire source with the high-speed airflow, which assists the wind-driven fire extinguishing and achieves rapid cooling and fire extinguishing of the fire source. The fire extinguishing agent can be water or other chemical agents. When the fire extinguishing agent is water, the fire extinguishing vehicle is a wind-water fire extinguishing vehicle. The fire extinguishing agent delivery pipe is preferably a flexible pipe to accommodate the expansion and contraction of the inner tube, the horizontal swing of the fan, and the up and down swing of the fire extinguisher.
[0025] The road obstacle clearing unit is located at the front end of the chassis. The hydraulic motor can be used to drive the obstacle clearing roller to rotate, and the cutting teeth can cut obstacles, so as to promptly clear and crush obstacles such as bushes on the road ahead. The hydraulic cylinder drives the swing frame and obstacle clearing roller to swing up and down at the front end of the combat vehicle, which can clear and crush tall trees. After clearing and crushing obstacles such as bushes and tall trees, the chassis can move smoothly, and at the same time, it can cut off the fire source and prevent the fire from spreading. This fire-fighting vehicle can be said to be a multifunctional fire-fighting vehicle.
[0026] The obstacle-clearing roller is installed at the inner lower part of the protective cover. When encountering thick trees, the cover as a whole or the front part of the cover is a movable cover. A push rod (such as an electric push rod, etc.) can be used to drive the cover as a whole or the movable cover to swing upward and backward, and open the cover as a whole or the movable cover to prevent the front end of the cover or the movable cover from colliding with obstacles, so that the cutting teeth on the obstacle-clearing roller can directly contact the obstacles and perform obstacle-clearing activities.
[0027] The protective lever extends forward. When the fire-extinguishing vehicle encounters a tall tree that collides with the front end of the protective lever, the protective lever will slightly bounce back to touch the micro switch (safety switch), triggering the stop function, the chassis stops moving, and then the road obstacle removal unit can be operated to perform obstacle removal activities. The controller is electrically connected to the power mechanism of the driving chassis, the up and down swing device, the horizontal swing device, the road obstacle removal unit, etc., to control the action of the multifunctional Feng Shui fire-extinguishing vehicle. The controller belongs to the prior art.
[0028] The remote controller belonging to the prior art can remotely control the fire-fighting vehicle, so that the operator can remotely control the fire-fighting vehicle to perform respective operations without approaching the fire source. The remote controller can wirelessly communicate with the controller to control the action of the multifunctional Feng Shui fire-fighting vehicle through the controller.
[0029] In order to drive the fan to swing horizontally, the fan housing can be directly hinged to one end of the connecting rod in the horizontal swing device, but at this time, the fan cannot rotate freely 360° relative to the chassis, and can only swing back and forth horizontally within a small angle range relative to the chassis under the drive of the horizontal swing device, which limits the operating range of the fan. For this reason, a horizontal swing device such as a rocker seat and a lock pin is added, and the two ends of the connecting rod are respectively hinged to the crank seat and the rocker seat; in this way, when the lock pin is inserted into the pin holes opened on the rocker seat and the housing at the same time, the horizontal swing power device drives the crank seat to rotate, and the connecting rod drives the rocker seat, the fan, the air outlet pipe, the up and down swing device, etc. to swing back and forth horizontally within a small angle range around the vertical axis; when the lock pin is only inserted into the pin hole opened on the rocker seat or the housing, the fan can rotate 360° around the vertical axis; the horizontal rotation of the fan is not restricted, and the flexibility of operation during fire extinguishing and the convenience of operation when not extinguishing the fire are stronger.
[0030] In order to drive the fire extinguisher to swing up and down, the rocker seat 2 in the up and down swinging device can be directly fixed on the pin shaft, and the two ends of the connecting rod 2 are respectively hinged with the crank seat 2 and the rocker seat 2. However, at this time, the fire extinguisher can only swing up and down reciprocatingly within a small angle range relative to the fan under the drive of the up and down swinging device, which limits the operating range of the fire extinguisher. For this reason, an up and down swinging device with a locking block, a locking bolt, etc. is adopted. The rocker seat 2 is rotated around the pin shaft axis as the center and is arranged at one end of the pin shaft. The locking block is fixed at one end of the pin shaft, and an arc groove with the pin shaft axis as the center is opened on the rocker seat 2. In this way, when the locking bolt is tightened, the up and down swinging power device drives the crank seat 2 to rotate, and the rocker seat 2 and the locking block are driven by the connecting rod 2 to swing up and down at a small angle around the pin shaft axis, and the fire extinguisher fixed on the pin shaft swings up and down at a small angle around the pin shaft axis. When the locking bolt is loosened, the rocker seat 2 can rotate around the pin shaft relative to the locking block, and the pin shaft, the locking block and the fire extinguisher can rotate around the pin shaft at a large angle, and the large angle refers to the center angle of the arc groove. Of course, if the locking bolt is removed from the locking block (the locking bolt does not pass through the arc groove), the pin, the locking block and the fire extinguisher can rotate around the pin in a wider angle range. In this way, the up and down swing of the fire extinguisher is basically unrestricted, and the flexibility of operation during fire extinguishing and the convenience of operation when not extinguishing the fire are stronger.

[0051] The fire extinguishing unit comprises a fan 1, a fire extinguisher 2, a horizontal swing device 3, and an up-and-down swing device 4.
[0052] The lower part of the fan housing 11 is rotatably arranged on the chassis around a vertical axis 12 via bearings or steel balls 13 .
[0053] The horizontal swing device 3 includes a crank seat 31, a motor 32 (horizontal swing power device) that drives the crank seat 31 to rotate around the crank seat axis, a rocker seat 33, a connecting rod 34 with two ends hinged to the crank seat 31 and the rocker seat 33, and a lock pin 35. The rocker seat 33 is rotatably arranged on the chassis or the housing 11 (the figure shows that it is rotatably arranged on the lower periphery of the housing 11) through bearings or steel balls with the vertical axis 12 as the axis. A pluggable lock pin 35 is arranged between the rocker seat and the housing. When the lock pin is inserted into the pin hole 36 opened on the rocker seat and the housing at the same time, the rocker seat 33 and the housing 11 cannot rotate relative to each other around the vertical axis; when the lock pin 35 is removed, or the lock pin 35 is only inserted into the pin hole opened on the rocker seat 33 or the housing 11, the rocker seat and the housing can rotate relative to each other around the vertical axis. There is one pin hole on the rocker seat 33. There are multiple pin holes 36 on the housing 11, distributed on the circumference of the housing with the vertical axis as the center. The pin holes on the rocker seat 33 and the pin holes 36 on the housing 11 are all in the same plane perpendicular to the vertical axis 12. When the lock pin is inserted into the pin hole on the rocker seat and any pin hole on the housing at the same time, the horizontal swing power device drives the crank seat to rotate, and drives the rocker seat, the fan including the housing, the air outlet pipe, and the up and down swing device to swing around the vertical axis in the horizontal plane through the connecting rod.
[0054] The fire extinguishing pipe 2 includes a coaxial outer pipe 21 and an inner pipe 22, and the inner pipe is axially slidably arranged in the outer pipe. The front end of the air outlet pipe 14 of the fan 1 is a rectangular box 15 of a cuboid shape; the pin 40 passes through the two side walls of the rectangular box and is rotatably arranged on the two side walls of the rectangular box through a bearing. The rear end of the outer pipe 21 is connected to a cylindrical pipe 23 passing through the front wall of the rectangular box. The cylindrical pipe 23 is coaxial with the pin 40. The two end plates of the cylindrical pipe are fixed on the pin 40 and are in sealing contact with the two side walls of the rectangular box. The two ends of the telescopic push rod (such as an electric push rod) 24 located in the inner pipe, namely the fixed end and the movable end, are respectively connected to the pin and the inner pipe, and the telescopic push rod drives the inner pipe to extend and retract relative to the outer pipe.
[0055] Ventilation holes are provided on the rear wall of the rectangular box and the wall of the cylindrical tube facing the rear wall of the rectangular box. The high-speed airflow generated by the fan 1 enters the fire extinguisher through the air outlet pipe 14, the vents on the rear wall of the rectangular box and the vents on the cylindrical tube, and then is ejected from the front end of the inner tube.
[0056] The rocker seat 43 is rotatably arranged at one end of the pin shaft with the axis of the pin shaft 40 as the center, and the locking block 48 is fixed at one end of the pin shaft. The rocker seat 43 is provided with an arc groove 46 with the axis of the pin shaft as the center, and the locking bolt 45 passes through the arc groove and is threadedly connected with the locking block 48. When the locking bolt 45 is tightened, the rocker seat 43 cannot rotate around the pin shaft relative to the locking block 48. When the locking bolt is loosened, the rocker seat 2 can rotate around the pin shaft relative to the locking block, and of course the maximum angle of rotation at this time is the central angle of the arc groove. When the locking bolt is removed, the angle of rotation of the locking block and the pin shaft relative to the rocker seat 2 around the axis of the pin shaft is not limited by the central angle of the arc groove, and the rotation angle will be larger. The up-and-down swing device 4 includes a crank seat 41, an up-and-down swing power device (such as a motor) 42 that drives the crank seat 41 to rotate around the axis of the crank seat 2, a connecting rod 44 whose two ends are respectively hinged to the crank seat 41 and the rocker seat 43, a locking bolt 45, and a locking block 48.
