[0019] Reference Figures 1 to 5 In one embodiment of this utility model, a drone for river patrol includes: The unmanned aerial vehicle body 100 is equipped with a controller and a mobile power supply that provides working voltage. A camera 110 is installed at the bottom of the unmanned aerial vehicle body 100. Multiple mounting rods 200 are spaced apart around the circumference of the unmanned aerial vehicle body 100; Multiple rotor mechanisms 300 are respectively installed on the free ends of multiple mounting rods 200, and a range radar 310 is provided at the bottom of each rotor mechanism 300; Multiple foot tubes 400 are tubular and are respectively installed in the middle of the length direction of the mounting rod 200. The lower end of the foot tube 400 is lower than the unmanned aerial vehicle body 100, and the upper end of the foot tube 400 is bent downward to form an elbow 410. Multiple sampling bottles 500 are detachably installed on multiple elbows 410, and an interface 510 is provided at the upper part of the side wall of each sampling bottle 500. A pumping system is installed on the upper part of the unmanned aerial vehicle body 100. The pumping system includes a suction pump and a pipeline system 610. The input end of the pipeline system 610 includes multiple parallel sub-pipes 611. The output end of the pipeline system 610 is connected to the suction pump. The sub-pipes 611 are connected to the interface 510 and are equipped with solenoid valves 612. The controller controls the operation of the rotor mechanism 300, the suction pump, the multiple solenoid valves 612, and the multiple range radars 310.

[0020] In existing technologies, the water sampling device of the drone affects the operation of the camera, and the ability to perform multiple samplings is relatively weak.

[0021] In this utility model, the up and down directions of the drone used for river patrol are fixed during use, so a certain direction indication is provided by using the up and down method.

[0022] The drone body 100 contains a controller and a mobile power supply that provides operating voltage. A camera 110 is installed at the bottom of the drone body 100 to perform image acquisition functions. The controller contains a positioning system, allowing the drone to fly along a set route, thereby enabling the camera 110 to acquire relevant image data. The mobile power supply provides power to the entire river patrol drone. The controller controls all components.

[0023] Multiple mounting rods 200 are spaced apart around the circumference of the unmanned aerial vehicle body 100, and the mounting rods 200 provide a structural foundation for the subsequent installation of the rotor mechanism 300.

[0024] Multiple rotor mechanisms 300 are respectively mounted on the free ends of multiple mounting rods 200. The form of the rotor mechanism 300 is not the focus, and various forms in the prior art are referred to. A range radar 310 is provided at the bottom of the rotor mechanism 300, and the distance between it and the base surface is detected by the operation of the range radar 310. The operating type of the range radar 310 can be ultrasonic or the like.

[0025] Multiple foot tubes 400 are tubular and installed at the middle of the mounting rod 200 along its length, with the foot tubes 400 positioned to avoid the rotor mechanism 300. The lower end of the foot tube 400 is lower than the unmanned aerial vehicle body 100, thus performing the function of foot support and also serving as the foundation for pumping water. The upper end of the foot tube 400 is bent downward to form an elbow 410.

[0026] Multiple sampling bottles 500 are detachably installed on multiple elbows 410, and water samples are stored in the sampling bottles 500. An interface 510 is located at the upper part of the side wall of the sampling bottle 500, and this interface 510 is the negative pressure inlet. The position of the interface 510 should not be too high, so that a larger amount of water sample can be stored in the sampling bottle 500.

[0027] The pumping system is installed on the upper part of the unmanned aerial vehicle (UAV) body 100. The pumping system includes a suction pump and a piping system 610. The suction pump can be a rotary pump or a peristaltic pump, etc. The input end of the piping system 610 includes multiple parallel sub-pipes 611. The output end of the piping system 610 is connected to the suction pump. The sub-pipes 611 are connected to an interface 510 and equipped with solenoid valves 612. The piping system 610 applies the negative pressure of the suction pump to a specific sampling bottle 500; the selection of the specific sampling bottle 500 is achieved through the operation of the solenoid valve 612.

[0028] The controller controls the operation of the rotor mechanism 300, the suction pump, multiple solenoid valves 612, and multiple range radars 310. Specifically, the controller achieves flight control by controlling the operation of the rotor mechanism 300. The distance between the UAV and the lower water surface is obtained through the operating signals of the range radars 310. The filling of a specific sampling bottle 500 is achieved by controlling the operation of the suction pump and multiple solenoid valves 612.

[0029] In summary, the drone body 100 is equipped with a camera 110 at its bottom to perform image acquisition; the distance to the water surface is obtained through the working signal of the distance radar 310, and the camera 110 can also perform auxiliary monitoring. Multiple sampling bottles 500 are detachably installed on the upper end of the foot tube 400 to store water samples. The lower end of the foot tube 400 is lower than the drone body 100, thus performing the foot function and also serving as the basis for pumping water. The pipeline system 610 applies the negative pressure of the suction pump to specific sampling bottles 500, and the selection of specific sampling bottles 500 is achieved by the operation of the solenoid valve 612.

[0030] In one embodiment, the foot tube 400 and the mounting rod 200 are detachably connected.

[0031] In this embodiment, the mounting of the foot tube 400 and the mounting rod 200 is made detachable, thus increasing the flexibility of use. When sampling is not required or during transport, the foot tube 400 can be removed for convenience. For example, the foot tube 400 can be pinned or threaded to the mounting rod 200.

[0032] In one embodiment, the foot tube 400 has a multi-segment connection structure in the length direction.

[0033] In this embodiment, the footing pipe 400 is broken in the length direction to meet different usage requirements. In one specific implementation, the footing pipe 400 includes multiple threaded sub-footing pipes. For example, if the river surface conditions are poor and a longer length of the footing pipe 400 is required, the entire length of the footing pipe 400 can be used for installation.

[0034] In one embodiment, the mounting position of the foot tube 400 on the mounting rod 200 is adjustable in the height direction.

[0035] In this embodiment, by adjusting the installation position of the foot tube 400, the usage height of the foot tube 400 can be changed, thereby adapting to different usage environments.

[0036] Reference Figures 1 to 2 In one embodiment, the bottom of the foot tube 400 is connected to a rubber seat 420 that is connected to the foot tube 400.

[0037] In this embodiment, a rubber seat 420 is provided at the bottom of the foot tube 400 to provide a cushioning effect. The rubber seat 420 should not interfere with the sampling process of the foot tube 400, therefore the rubber seat 420 should also be tubular. The material of the rubber seat 420 can be silicone or polyurethane, etc.

[0038] In one embodiment, the number of mounting rods 200 is four, six, or eight.

[0039] In this embodiment, several common structural forms are presented; other embodiments may use different quantities. Changing the number of mounting rods 200 will correspondingly change the number of rotor mechanisms 300 and foot tubes 400.

[0040] In one embodiment, the suction pump is an impeller centrifugal type.

[0041] In this embodiment, the impeller centrifugal suction pump has the advantages of simple structure and high working efficiency, and uses the impeller rotation to generate negative pressure to achieve the suction effect.

[0042] In one embodiment, a counterweight is detachably connected to the lower part of the foot tube 400.

[0043] In this embodiment, a counterweight is installed at the foot tube 400 to lower the center of gravity of the drone used for river patrol. The connection between the counterweight and the foot tube 400 can be varied, such as snap-fit ​​or bolt connection.

[0044] In one embodiment, the connection between the sampling bottle 500 and the elbow 410 is a threaded connection.

[0045] In this embodiment, the sampling bottle 500 is installed using a threaded connection, which has the advantages of simplicity and stability.

[0046] Reference Figure 1 In one embodiment, the pumping system includes a housing 620, and the suction pump and the piping system 610 are both installed in the housing 620. The housing 620 is detachably connected to the unmanned aerial vehicle body 100.

[0047] In this embodiment, the modularization of the pumping system enhances its versatility. When sampling is not required, the pumping system can be removed by disconnecting the connection between the sub-pipe 611 and the sampling bottle 500.

[0048] In one embodiment, the range radar 310 is of the ultrasonic type.

[0049] In this embodiment, limiting the range radar 310 to the ultrasonic type has the advantages of being cost-effective and reliable.

[0050] In summary, the UAV for river patrol provided by this utility model has a camera 110 installed at the bottom of the UAV body 100 to perform image acquisition; the distance between the UAV and the water surface is obtained through the working signal of the distance radar 310, and the camera 110 can also perform auxiliary monitoring. Multiple sampling bottles 500 are detachably installed on the upper end of the foot tube 400 to store water samples. The lower end of the foot tube 400 is lower than the UAV body 100 to perform the foot function and also serve as the basis for pumping water, while avoiding the camera 110. The pipeline system 610 applies the negative pressure of the suction pump to the specific sampling bottle 500, and the selection of the specific sampling bottle 500 is achieved by the operation of the solenoid valve 612.
