Description

Technical Field

[0001] The present invention relates to the technical field of smoke exhaust robots, and in particular to a mobile smoke exhaust robot for fire emergency rescue. Background Art

[0002] Due to the accelerating urbanization process and modern industrial revolution, various large-scale fires and leakage accidents of dangerous chemicals occur frequently. Such accidents are often accompanied by a large amount of flammable, explosive, and toxic gases and smoke, causing great harm to on-site personnel and the surrounding environment, and bringing great difficulties and risks to fire fighting and on-site rescue. According to statistics, more than 85% of the casualties in fires are caused by inhaling toxic smoke. Therefore, fire smoke exhaust robots are being applied more quickly.

[0003] As a type of special robot, fire smoke exhaust robots play a crucial role in fire fighting and emergency rescue. Fire robots can replace fire rescue personnel to enter dangerous disaster sites such as flammable, explosive, toxic, oxygen-deficient, and thick-smoke areas, effectively solving problems such as personal safety and insufficient data information collection faced by firefighters in the above-mentioned places.

[0004] According to the fire smoke exhaust robot applicable to complex terrains disclosed in the publication number CN222092388U, which includes a base, two groups of moving components are fixedly connected inside the base, two groups of auxiliary components are movably connected to the front of the base, a fire extinguishing component is fixedly connected to the top of the base, and a smoke exhaust component is fixedly connected to the top. Through the set auxiliary components, when the fire smoke exhaust robot encounters a bumpy road section and the middle section of the bottom plate gets stuck in a pit, two servo motors are started to drive the screw to rotate. The inside of the lifting plate is threadedly connected to the surface of the screw. When the screw rotates, it drives the lifting plate to move up and down. The lifting plate drives the support rod and the support plate to descend and contact the ground, causing the inclined section of the bottom plate to rise. Subsequently, one group of moving components moves backward, enabling the fire smoke exhaust robot to get out of the stuck road section and preventing the fire smoke exhaust robot from being stuck during the rescue.

[0005] The above-mentioned method of setting auxiliary components can prevent the smoke exhaust robot from being stuck by pitted terrain during the traveling process, which has a certain practicality. By observing the attached drawings, when the smoke exhaust component and the fire extinguishing component of this device are turning, the angle can only be changed by turning the vehicle body, resulting in inconvenience in use.

[0029] With the above scheme: The robot body 1 is provided with a monitoring camera component for the operator to identify the road at the fire extinguishing site. Through the angle adjustment component 3, the situation where the mobile base 11 needs to be steered and adjusted when the smoke exhaust cylinder 41 changes its angle can be reduced, increasing the flexibility and functionality of the smoke exhaust cylinder 41 during smoke exhaust.

[0030] Refer to Figure 1 and Figure 6 , a protective net plate 43 for blocking burning impurities is fixedly installed on the side of the inside of the smoke exhaust cylinder 41 close to the smoke exhaust fan 42;

[0031] With the above scheme: The protective net plate 43 is a filter net plate, which can block the unburned impurities in the smoke exhaust process outside the smoke exhaust cylinder 41, reducing the damage to the smoke exhaust fan 43 caused by the impurities entering the inside of the smoke exhaust cylinder 41.

[0032] Refer to Figure 1 and Figure 6A water pump 24 is fixedly installed on the top of the water tank 21, a water spray pipe 26 is fixedly installed on the top of the smoke exhaust pipe 41, and a connecting hose 25 is fixedly installed in the middle of the water pump 24 and the water spray pipe 26.

At the bottom end of the support column 44, a driven bevel gear 35 meshingly connected with the driving bevel gear 34 is fixedly installed. The angle adjustment component 3 further includes a mounting block 36 rotatably connected to the outer periphery of the support column 44 and located between the driven bevel gear 35 and the smoke exhaust cylinder 41. At one end of the mounting block 36 and on one side of the driving bevel gear 34, a first L-shaped connecting arm 37 is fixedly installed, and the first L-shaped connecting arm 37 is rotatably connected to the rotating shaft 33. At one end of the mounting block 36 and on the side opposite to the first L-shaped connecting arm 37, a second L-shaped connecting arm 38 is fixedly installed.

[0040] Refer to Figure 1 and Figure 6 , a protective mesh plate 43 for blocking burning impurities is fixedly installed on one side of the inside of the smoke exhaust cylinder 41 close to the smoke exhaust fan 42;

[0041] Adopting the above solution: The protective mesh plate 43 is a filter mesh plate, which can block the unburned impurities in the smoke exhaust process outside the smoke exhaust cylinder 41, reducing the damage to the smoke exhaust fan 43 caused by impurities entering the inside of the smoke exhaust cylinder 41.

Through the water pump 24, the connecting hose 25 and the water spray pipe 26, the fire at the fire scene can be initially dealt with, reducing the spread of the fire

[0044] The working principle of the present invention is: When using the robot body 1 for smoke exhaust work, the smoke generated at the fire scene can be exhausted through the smoke exhaust fan 42 inside the smoke exhaust pipe 41. When it is necessary to change the air outlet angle of the smoke exhaust pipe 41, the staff starts the first rotating motor 32 to drive the rotating shaft 33 to rotate. As the rotating shaft 33 rotates, the driving bevel gear 34 will rotate, and then drive the driven bevel gear 35 meshed with the driving bevel gear 34 to rotate. As the driven bevel gear 35 rotates, the support column 44 will rotate, thereby changing the smoke exhaust angle of the smoke exhaust pipe 41 in the horizontal direction, increasing the convenience of adjusting the smoke exhaust angle of the smoke exhaust pipe 41. At the same time, by starting the second rotating motor 310 to work and driving the second L-shaped connecting arm 38 to rotate through the connecting shaft 39. As the second L-shaped connecting arm 38 rotates, the smoke exhaust pipe 41 will be driven to adjust the angle in the vertical direction through the mounting block 36. Through the angle adjustment assembly 3, the situation where the base 11 needs to be moved and turned to adjust the angle when the smoke exhaust pipe 41 changes the angle can be reduced, increasing the flexibility and functionality of the smoke exhaust pipe 41 during smoke exhaust.
