Description

Technical Field

[0001] This application relates to the technical field of drone accessories, and in particular to a precision acquisition mechanical structure suitable for drones. Background Technology

[0002] Drone sampling refers to using drones as flight platforms, equipped with sampling devices. When drones operate over bodies of water such as rivers, lakes, and oceans, they can collect water samples by attaching water samplers to determine whether rivers are polluted or whether the marine ecosystem is healthy.

[0003] A search revealed Chinese patent application CN202221370599.4, which discloses a device for unmanned aerial vehicles (UAVs), specifically a UAV water sampler. The device includes a mounting plate with multiple support legs fixedly connected to its bottom. These support legs are arranged in a ring around the bottom of the mounting plate, and each support leg has a float plate fixedly connected to its end furthest from the mounting plate. The bottom of the mounting plate also has multiple water storage mechanisms arranged in a ring, each including a placement mesh frame detachably connected to the mounting plate. This UAV water sampler, through the multiple water storage mechanisms arranged in a ring around the bottom of the mounting plate and the water intake mechanism located between these mechanisms, allows users to collect water samples from different regions without precise positioning. This solves the problem of complex setups and high positioning requirements between the pump outlet and the inlet of the sampling bottle in existing UAV water samplers.

[0004] Regarding the aforementioned technologies, the inventors have discovered the following drawbacks: In actual use, when the sampling bottle carried by the drone moves in the air, it may shake violently due to the influence of external wind, causing the sampled water to spill and resulting in insufficient sampling, which necessitates resampling and thus affects the sampling efficiency. Utility Model Content

[0005] To address the problems mentioned in the background section, this application provides a precision data acquisition mechanical structure suitable for unmanned aerial vehicles (UAVs).

[0006] This application provides a precision data collection mechanical structure suitable for UAVs, which adopts the following technical solution: including a central plate, a floating component is provided on the lower side of the central plate, a sampling disk is rotatably fitted at the center of the lower side of the central plate, a water pump is fixedly connected to the lower side of the sampling disk, a telescopic pipe is fixedly connected to the input end of the water pump, and a drive component that cooperates with the telescopic pipe is provided on the lower side of the sampling disk.

[0007] Two L-shaped plates are fixedly connected to the lower side of the central plate. Sampling cups are provided on the inner walls of the L-shaped plates. A pressing groove is opened on one side of the inner wall of each L-shaped plate. A movable block is slidably and elastically fitted on the inner wall of the pressing groove. A protective block that contacts the sampling cup is fixedly connected to one side of the movable block. A lifting plate is fixedly connected to the lower side of the sampling plate. The lifting plate and the protective block are fitted together. A drain pipe is fixedly connected to the input end of the water pump.

[0008] Optionally, the floating assembly includes multiple support rods fixedly connected to the lower side of the central plate and two floating plates fixedly connected to the lower ends of the multiple support rods.

[0009] Optionally, the drive assembly includes a drive motor fixedly connected to the lower side of the sampling plate, a rust-proof screw fixedly connected to the output end of the drive motor, and a force-bearing block fixedly connected to one side of the telescopic tube and threadedly engaged with the rust-proof screw.

[0010] Optionally, a tightening groove is provided on one side of the inner wall of each of the two L-shaped plates, and a bidirectional lead screw is rotatably fitted on the inner wall of each tightening groove. A tightening block is threaded onto the upper part of each bidirectional lead screw, and the tightening block is slidably fitted with the tightening groove.

[0011] Optionally, a flip motor is fixedly connected to the upper side of the central plate, and the output end of the flip motor is fixed to the upper side of the sampling plate.

[0012] Optionally, the lower side of the telescopic tube is provided with a thread, and a filter head is threaded on the outer side of the thread.

[0013] Optionally, two connecting blocks are fixedly connected to the upper side of the central plate, and a limiting rod that slides with the force-bearing block is fixedly connected to the lower side of the sampling plate.

[0014] In summary, this application includes the following beneficial technical effects:

[0015] This invention incorporates components such as a sampling cup, a pressure groove, a movable block, a protective block, and a lifting plate. Rotating the sampling disc causes the lifting plate and drain pipe to flip. When the lifting plate contacts the protective block, its inclined surface lifts the block, causing it to move upwards. The drain pipe then moves to the top of the sampling cup to pump water into it. After sampling, rotating the sampling disc separates the lifting plate from the protective block. The movable block then experiences a downward pressure within the pressure groove, effectively sealing the sampling cup by covering it with the protective block. This prevents spillage during sampling and improves stability.

[0016] This invention, by setting up a drive component, a water pump, and a telescopic pipe, can drive the anti-rust screw to rotate by starting the drive motor, which in turn pushes the force block downward, thereby extending the telescopic pipe to extract water from different heights. This facilitates subsequent testing and improves the accuracy of the data collection. Attached Figure Description

Detailed Implementation

[0022] The following is in conjunction with the appendix Figure 1 —4. This application will be described in further detail.

[0023] This application discloses a precision data acquisition mechanical structure suitable for unmanned aerial vehicles (UAVs). For example... Figure 1-4 As shown, it includes a central plate 1, a floating component 2 is provided on the lower side of the central plate 1, a sampling disk 3 is rotatably fitted at the center of the lower side of the central plate 1, a water pump 4 is fixedly connected to the lower side of the sampling disk 3, a telescopic pipe 5 is fixedly connected to the input end of the water pump 4, and a driving component 6 that cooperates with the telescopic pipe 5 is provided on the lower side of the sampling disk 3.

[0024] Please see Figure 1 The floating assembly 2 includes multiple support rods 201 fixedly connected to the lower side of the central plate 1 and two floating plates 202 fixedly connected to the lower ends of the multiple support rods 201. When sampling, the central plate 1 can float on the water surface by contacting the floating plates 202.

[0025] Please see Figure 3The drive assembly 6 includes a drive motor 601 fixedly connected to the lower side of the sampling plate 3, a rust-proof screw 602 fixedly connected to the output end of the drive motor 601, and a force-bearing block 603 fixedly connected to one side of the telescopic pipe 5 and threadedly engaged with the rust-proof screw 602. By starting the drive motor 601, the rust-proof screw 602 is rotated, which pushes the force-bearing block 603 downward, thereby extending the telescopic pipe 5 and enabling the extraction of water layers at different heights. This facilitates subsequent testing and improves the accuracy of the sampling.

[0026] Please see Figure 3 A flip motor 15 is fixedly connected to the upper side of the central plate 1. The output end of the flip motor 15 is fixed to the upper side of the sampling disk 3. The flip motor 15 facilitates the driving of the sampling disk 3. The flip motor 15 can be connected to the UAV and connected to the corresponding control terminal via a network.

[0027] Please see Figure 3 The lower side of the telescopic pipe 5 is provided with a threaded line 16, and a filter head 17 is threaded on the outer side of the threaded line 16. By connecting the filter head 17 to the outer side of the threaded line 16 on the telescopic pipe 5, the lower side of the telescopic pipe 5 can be protected to prevent the pump 4 from being damaged by drawing out too large algae.

[0028] Please see Figure 1 and Figure 3 Two connecting blocks 19 are fixedly connected to the upper side of the central plate 1. The connecting blocks 19 can be used to fix the UAV. A limiting rod 20 that slides with the force block 603 is fixedly connected to the lower side of the sampling plate 3. When the force block 603 moves up and down, the limiting rod 20 can limit the force block 603 and improve the stability during movement.

[0029] Two L-shaped plates 7 are fixedly connected to the lower side of the central plate 1. Sampling cups 8 are provided on the inner walls of the L-shaped plates 7. A pressing groove 9 is opened on one side of the inner wall of each of the two L-shaped plates 7. A movable block 10 is slidably and elastically fitted on the inner wall of the pressing groove 9. A spring is provided between the pressing groove 9 and the movable block 10. The spring can always press the movable block 10 so that the protective block 11 covers the upper side of the sampling cup 8. A protective block 11 that contacts the sampling cup 8 is fixedly connected to one side of the movable block 10. A lifting plate 12 is fixedly connected to the lower side of the sampling plate 3. The lifting plate 12 and the protective block 11 cooperate with each other. A drain pipe 18 is fixedly connected to the input end of the water pump 4.

[0030] Please see Figure 4Each of the two L-shaped plates 7 has a tightening groove 13 on one side of its inner wall. The inner walls of the two tightening grooves 13 are rotatably fitted with a double-acting screw 14. The upper part of the double-acting screw 14 is threaded with a tightening block 21. The tightening block 21 is slidably fitted with the tightening groove 13. By rotating the double-acting screw 14, the two tightening blocks 21 are driven to move in similar directions, thereby fixing the sampling cup 8 and improving its stability in the air.

[0031] The implementation principle of a precision data collection mechanical structure applicable to drones in this application embodiment is as follows: During use, the centralized plate 1 is connected and fixed to the drone, and the internal drive components are connected to the drone. The drone moves the centralized plate 1 to the corresponding river surface. After the floating plate 202 comes into contact with the water, it floats up. By starting the drive motor 601, the rust-proof screw 602 is rotated, which pushes the force block 603 to move downward, thereby causing the telescopic tube 5 to extend, so as to extract water layers at different heights, which is convenient for subsequent detection and improves the accuracy of data collection.

[0032] During the extraction process, the water pump 4 is activated to extract water from the telescopic pipe 5, and then the water is discharged from the drain pipe 18. By rotating the sampling disc 3, the lifting plate 12 and the drain pipe 18 can be rotated. When the lifting plate 12 contacts the protective block 11, the inclined surface of the lifting plate 12 will lift the protective block 11, causing the protective block 11 to move upward. The drain pipe 18 will then move to the upper side of the sampling cup 8 to pump water into the sampling cup 8. After sampling is completed, the sampling disc 3 is rotated, and the lifting plate 12 separates from the protective block 11. The movable block 10 will be pressed downward inside the pressure groove 9, so that the protective block 11 covers the upper side of the sampling cup 8, sealing the sampling cup 8 and preventing the sample from being spilled due to shaking, thereby improving the stability during sampling.

[0033] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
