The mobile unit comprises a base for supporting and limiting the loads of the various components; a track assembly connected to the base's lower working surface via a docking box for adjustable movement; a monitoring unit positioned on the upper working surface of the base, enabling omnidirectional monitoring; and a blower unit positioned on the upper working surface of the base, at a predetermined operating distance from the monitoring unit, enabling smoke dispersal within a predetermined range.

[0004] However, the above device has the following problems when in use:

[0005] When the device is in use, in order to ensure its stability when spraying water, it has to adopt a crawler design, which results in a slower running speed and higher energy consumption during daily inspection activities. Although the existing wheeled fire inspection robot has a fast inspection speed, it is not stable enough during operation due to the recoil force and inertia when performing fire fighting activities. Utility Model Content

[0006] The purpose of the present utility model is to solve the problems existing in the prior art, and to propose a patrol robot with good stability. Only when fire-fighting activities are carried out, there will be water inside the water tank, which increases the deadweight and ensures stability. During the patrol, there is no water inside the water tank, the deadweight is low, and it is easy to move. The presence or absence of water inside the water tank can be controlled according to actual needs, thereby adapting to different usage requirements.

[0007] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0008] A patrol robot with good stability comprises a housing, a wheel body rotatably mounted on the housing, a pan-tilt platform provided on the housing, and a camera assembly rotatably mounted on the pan-tilt platform;

[0011] One end of the main pipe is fixedly equipped with a connection port.

[0012] A water tank is arranged inside the shell, and a drain outlet and a water inlet are opened on the water tank.

[0013] Preferably, a branch pipe is embedded in the main pipe, a bellows is fixedly installed at the other end of the branch pipe, and the bellows is connected to the water inlet.

[0014] Preferably, a control valve is provided on the branch pipe.

[0015] Preferably, stretching devices are evenly and equidistantly provided on the shell, and a water tank is fixedly installed on the other end of the stretching device.

[0016] Preferably, the stretching device includes a fixed cylinder, which is fixedly installed inside the shell, a sliding cylinder is fixedly installed on the fixed cylinder, the sliding cylinder is fixedly connected to the water tank, a spring is fixedly installed inside the fixed cylinder, and the other end of the spring is fixedly installed on the sliding cylinder.

[0017] Preferably, a friction layer is embedded on the side of the water tank facing away from the housing.

[0019] (1) The utility model is provided with a water tank, a spray pipe, a connecting hose, a main pipe, a connecting port, a valve body, a drain port, a branch pipe, a bellows and a water inlet. The main pipe can provide water for the spray pipe and the water tank. Only when the fire-fighting activity is carried out, there will be water inside the water tank, which can increase the deadweight and ensure the stability during operation. During the inspection, there is no water inside the water tank, which makes the deadweight lower and easy to move. The presence or absence of water inside the water tank can be adjusted according to actual needs, thereby adapting to different usage requirements.

[0028] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0029] See also Figures 1 to 6 A patrol robot with good stability includes a shell 1 on which a wheel body 2 is rotatably mounted. By rotating the wheel body 2, the robot moves, thereby realizing patrol activities.

[0030] The housing 1 is provided with a pan-tilt head 4 on which a camera assembly 5 is rotatably mounted. The camera assembly 5 can be rotated on the pan-tilt head 4 and the pitch angle can be adjusted, thereby making the camera range wider and facilitating daily use.

[0031] The housing 1 is fixedly mounted with a mounting frame 6, and a spray pipe 7 is rotatably mounted on the mounting frame 6. The spray pipe 7 is used to spray water for fire extinguishing. The angle of the spray pipe 7 can be adjusted to meet different usage requirements.

[0032] A main pipe 9 is fixedly installed inside the housing 1, and a delivery pipe 13 is embedded in the main pipe 9. The delivery pipe 13 is connected to the injection pipe 7 through a connecting hose 8. The design of the connecting hose 8 can adapt to the rotation of the injection pipe 7.

[0033] Preferably, the delivery pipe 13 should be provided with a valve and a corresponding pressure boosting device.

[0034] One end of the main pipe 9 is fixedly mounted with a connection port 10;

[0035] By quickly connecting the connection port 10 to the fire hose, water transportation can be achieved, thereby providing a continuous water source for the injection pipe 7.

[0036] A water tank 3 is provided inside the housing 1 , and a water outlet 12 and a water inlet 18 are provided on the water tank 3 .

[0037] The main pipe 9 also provides a water source for the water tank 3, so that there will be water inside the water tank 3 only when fire fighting activities are carried out, which can increase the deadweight and ensure stability during operation. During inspection, there is no water inside the water tank 3, the deadweight is low, and it is easy to move.

[0038] A branch pipe 16 is inlaid on the main pipe 9 , and a bellows 17 is fixedly installed on the other end of the branch pipe 16 . The bellows 17 is connected to the water inlet 18 .

[0039] A control valve 11 is provided on the branch pipe 16 .

[0040] When in use, the control valve 11 is opened, and the water flows into the branch pipe 16, and then enters the water tank 3 through the water inlet 18, so that the water can be added smoothly. The existence of the bellows 17 can smoothly perform the water injection activity while the height of the water tank 3 changes through the deformation of the bellows 17 itself.

[0041] Stretching devices 14 are evenly and equidistantly provided on the housing 1 , and a water tank 3 is fixedly mounted on the other end of the stretching device 14 so that the height can be changed.

[0042] The stretching device 14 includes a fixed cylinder 19, which is fixedly installed inside the shell 1. A sliding cylinder 21 is fixedly installed on the fixed cylinder 19, and the sliding cylinder 21 is fixedly connected to the water tank 3. A spring 20 is fixedly installed inside the fixed cylinder 19, and the other end of the spring 20 is fixedly installed on the sliding cylinder 21.

[0043] When the weight inside the water tank 3 gradually increases, since the sliding cylinder 21 is connected to the water tank 3, the spring 20 will be stretched under the action of gravity, and then the sliding cylinder 21 moves on the fixed cylinder 19, and the height of the water tank 3 gradually decreases. When the corresponding mass of water is injected, the water tank 3 directly contacts the ground, which can increase the contact area and further improve stability.

[0044] A friction layer 15 is embedded on the side of the water tank 3 facing away from the shell 1. The friction layer 15 is in direct contact with the ground, and corresponding patterns are provided on the friction layer 15, which can further increase the friction with the ground and ensure the stability of the equipment operation.

[0045] The working process of the utility model: first, when conducting inspections, the interior of the water tank 3 is hollow, without water, and has a low deadweight, making it easy to move. By rotating the wheel body 2 and moving the robot, the inspection activity is realized. The camera component 5 can rotate on the pan-tilt head 4, and the pitch angle can be adjusted, so that the camera range is wider and convenient for daily use.

[0046] When a dangerous situation is detected, it is reported quickly. The operator rushes to connect the connection port 10 to the fire hose quickly, opens the control valve 11, and the water flows into the branch pipe 16 and then enters the water tank 3 through the water inlet 18, so that the water can be added smoothly.

[0047] When the weight inside the water tank 3 gradually increases, since the sliding cylinder 21 is connected to the water tank 3, the spring 20 will be stretched under the action of gravity, and then the sliding cylinder 21 moves on the fixed cylinder 19, and the height of the water tank 3 gradually decreases. When the corresponding mass of water is injected, the water tank 3 directly contacts the ground, which can increase the contact area and further improve stability.

[0048] A friction layer 15 is embedded on the side of the water tank 3 facing away from the shell 1. The friction layer 15 is in direct contact with the ground, and corresponding patterns are provided on the friction layer 15, which can further increase the friction with the ground and ensure the stability of the equipment operation.

[0049] Afterwards, the valve and the pressure-boosting device on the delivery pipe 13 are opened, and the spray pipe 7 can spray out the fire-extinguishing water flow. The angle of the spray pipe 7 can be adjusted to meet different usage requirements.

[0050] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
