Background
With the rapid development of social economy and the particularity of construction and enterprise production, the accident potential of leakage, combustion, explosion and collapse of chemical dangerous goods and radioactive substances is increased, and the accident rate is correspondingly increased. In case of disaster accidents, firefighters can rush into the scene without corresponding equipment when facing high temperature, darkness, toxicity, dense smoke and other harmful environments, so that the tasks can not be completed, and casualties can be increased.
The fire-fighting robot is one of special robots and plays a role in fire extinguishing and emergency rescue. A fire-fighting robot generally has a vehicle body, a motor connected to a power supply is provided on the vehicle body, a wheel linked with the motor is provided under the vehicle body, and a spraying device for spraying a fire-fighting liquid is provided on the vehicle body. In the existing fire-fighting robot, single-stage pressurization is adopted at the inlet end and the nozzle end, and pressurization is not adopted, so that the pressurization effect is not obvious, the work is unstable, and the fire control effect is very poor. The walking device of the fire-fighting robot generally adopts a crawler type or a wheel type, the crawler type device is expensive and high in damage rate, a robot main body cannot deform correspondingly according to the terrain, the adaptability is poor, the wheel type walking device is high in requirement on the terrain condition, the fire is complex, avoidance cannot be achieved when the road surface is complex, meanwhile, the fire resistance of the wheel type walking device is poor, and the fire extinguishing efficiency is greatly reduced. In the aspect of chassis drive, current fire-fighting robot technique uses brush motor control walking and turns to usually, and its control accuracy is poor to chassis height and chassis gradient can not adjust, and this makes machine theme flexibility and environmental suitability poor, and the instability of operation improves, greatly reduced work efficiency.

The working principle of the fire-fighting robot is as follows: when the fire-fighting robot starts to move, firstly, two walking feet 5 close to the outside on the left side and a middle walking foot 5 on the right side form a triangular bracket so as to ensure that the gravity center of the robot is positioned in a triangle, so that the robot has stability and is not easy to fall down; the two walking feet 5 which are close to the outside on the right side and the walking foot 5 which is in the middle of the left side are lifted to prepare for swinging forwards to advance; the three feet 5 swing forward to stride; because the two walking feet 5 close to the outer part of the right side and the walking feet 5 in the middle of the left side swing in a striding mode, the supporting walking feet (the two walking feet 5 close to the outer part of the left side and the walking feet 5 in the middle of the right side) swing at a certain angle, and the whole robot moves forwards by half step length while supporting the chassis of the robot; after the robot integrally moves forward by half step length, the swing footsteps (the two footsteps 5 outside the right side and the footstep 5 in the middle of the left side) are quickly put down to take over the new triangular support formed by the two footsteps 5 outside the left side and the middle footstep 5 in the right side, the gravity center position of the robot is stably positioned in a triangular support formed by the two footsteps 5 outside the right side and the three support footsteps 5 in the middle of the left side, the two footsteps 5 outside the left side and the middle footstep 5 in the right side are lifted up to enter a swing state, preparation for forward striding is made, the two footsteps 5 outside the left side and the middle footstep 5 in the right side swing forwards, the two footsteps 5 outside the right side and the middle footstep 5 in the left side support the chassis while driving the robot integrally to move forward by half step length, and the whole period is formed. In order to guarantee the step flexibility and the whole adaptability of the robot under the severe environment, the robot can adjust a stepping motor I36 to change the stride height of the robot, the gravity center height of the robot is changed by adjusting a stepping motor II 39, and the walking step length of the robot is changed by adjusting a stepping motor III 40.
When the robot walks, the feet fall to the ground to generate larger impact force, which is very easy to damage the body. In order to ensure the walking flexibility and the overall adaptability of the robot in a severe environment, the robot can adjust the rotating angle of a stepping motor I36, so that the height of the walking of the robot is changed on the basis of ensuring the walking flexibility of the robot, and further the walking height of the robot is changed; the height of the gravity center of the robot is changed by adjusting the rotating angle of the stepping motor II 39, and the walking step length of the robot is changed by adjusting the rotating angle of the stepping motor III 40. In the walking process of the robot, the feet can generate larger impact force instantly when falling to the ground, so that the machine body is extremely easy to damage, and the passive suspension mechanism spring 41 and the hydraulic rod 35 of the feet of the robot form a shock absorbing mechanism, so that the complexity of the feet can be effectively reduced, the working stability of the machine is enhanced, and the shock generated in the motion process is passively absorbed.
When fire-fighting robot began to carry out the task of putting out a fire, fire-fighting lance 1 gets into operating condition, steering wheel 12 rotated certain angle, drive I14 and II 15 motions of connecting rod, make the opening angle of connecting rod I14 and II 15 of connecting rod diminish, I16 of rifle mouth and II 17 of rifle mouth open this moment, motor I25 and II 29 on the water pump 9 begin high-speed rotatory fire-fighting water pressurization for the rifle pipe, when fire-fighting lance 1 aimed at the fire source, governing valve 20 and check valve 21 adjust suitable operating position and implement to put out a fire.
The invention has the following beneficial effects:
1. the fire-fighting robot can utilize the unique sole sensor to perform motion feedback on toes, can effectively avoid high-altitude falling objects generated by combustion in the walking process, and can improve the safety of fire-fighting operation;
2. the high-pressure fire-fighting lance head has large sweeping area of the outlet, can effectively extinguish fire near the fire point which cannot be reached by fire fighters by using the high-pressure fire-fighting lance, saves time and labor, and is safe and reliable;
3. the high-pressure water gun is pressurized by a secondary pump, so that the pressure of the water pump is higher, and the fire is more effectively extinguished;
4. the fire-fighting robot adopts a frame type structure, so that the weight of a main body can be reduced, the fire-fighting robot is convenient to mount and dismount, and meanwhile, the function of the fire-fighting robot adopts a modular design, so that the replacement of easily damaged parts is convenient;
5. six limbs of the fire-fighting robot can move in multiple degrees of freedom, and the height of the chassis can be adjusted, so that the robot can make different motion changes according to complex terrains, and operation is convenient to implement.
