[0001] This utility model relates to the field of unmanned aerial vehicle (UAV) technology, specifically to a UAV used for water conservancy engineering inspection. Background Technology

[0002] Water conservancy projects play a vital role in regulating surface water and groundwater, mitigating floods, and ensuring the rational allocation of water resources. Water quality testing is an important component of water conservancy project maintenance and water resource management. To ensure the safe and stable operation of water conservancy projects, it is necessary to test the water quality in lakes.

[0003] Currently, water sampling and testing are usually carried out using drones. However, drones can only carry one water storage component at a time, requiring multiple round trips for sampling. This greatly increases the working time of operators and reduces work efficiency. Summary of the Invention

[0004] The purpose of this invention is to provide a drone for water conservancy project inspection, so as to solve the problems mentioned in the background art.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a drone for water conservancy engineering inspection, comprising:

[0006] The device includes a limiting box with a rotating plate rotatably connected to its inner wall. Four collection boxes are located inside the limiting box, and four water inlets are formed on its outer surface. An inner tube is fixedly connected inside the limiting box. The device body is located on the top of the limiting box. A curved groove is formed inside the rotating plate, with one end of the groove matching a water inlet, and the other end located at the center of the opening at the top of the collection box. This groove is used to introduce external water into the collection box for sampling. A second motor is located at the bottom of the device body and is fixedly connected to it. The output end of the second motor is fixedly connected to... A threaded rod has its outer surface connected to the internal thread of the inner tube, and the internal thread of the inner tube is compatible with the thread on the outer surface of the threaded rod. This is used to move the limiting box up and down, allowing it to be inserted into the water for sampling. A first motor is located on the inner top wall of the limiting box, and its output end is fixedly connected to a first gear via a coupling. A second gear is fixedly connected to the upper surface of the rotating plate, and the outer surface of the second gear meshes with the outer surface of the first gear to drive the rotating plate to rotate. This is used to adjust the position of the curved groove, which allows water samples to be introduced into different collection boxes at different locations.

[0007] Preferably, a handle is fixedly connected to the bottom of the collection box, a limiting post is fixedly connected to the bottom of the limiting box, a locking plate is fixedly connected to the outer surface of the limiting post, the upper surface of the locking plate is in contact with the lower surface of the collection box, and the locking plate abuts against the bottom of the collection box to limit the collection box.

[0008] Preferably, the surface of the device body is provided with four blades, and the bottom of each of the four blades is provided with a float to keep the device afloat in the event of an accidental fall, thus protecting the device.

[0009] Preferably, two supports are fixedly connected to the lower surface of the device body to support the device, allowing it to be raised and lowered safely.

[0010] Preferably, each of the two brackets has a connecting plate fixedly connected inside, and each of the two connecting plates has a limit groove on its outer surface. The outer surface of the limit box has two protrusions fixedly connected, and the outer surface of the protrusions is slidably connected to the inside of the limit groove to limit the downward movement of the limit box.

[0011] Preferably, the interior of the second gear is slidably connected to the outer surface of the inner tube, and the interior of the rotating plate is slidably connected to the outer surface of the inner tube.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] This invention utilizes a second motor to rotate a threaded rod, which in turn drives the inner tube through a threaded transmission. This causes the protrusion to move downwards under the limiting action of the limiting groove, allowing the limiting box to insert below the water surface. Simultaneously, the first motor is activated, driving the first gear to rotate. The first gear meshes with the second gear, further rotating the rotating plate. This aligns the curved groove with a water inlet hole, placing the end of the curved groove away from the inlet hole directly above a collection box. Water flows into the collection box through the inlet hole and the curved groove. After sampling at this point, the first motor is activated again to rotate the rotating plate, sealing the sampled collection box. The process is repeated at the next sampling point, where the first motor is activated again to rotate the plate, aligning the curved groove with the next collection box and inlet hole. This sampling operation is repeated, quickly completing the sampling work and improving work efficiency. Attached Figure Description

[0021] Please refer to the accompanying drawings. This embodiment discloses a drone for water conservancy engineering testing. As shown in Figure 1, it includes: a limiting box 6, a rotating plate 14 rotatably connected to the inner wall of the limiting box 6 to facilitate the introduction of water samples into the collection box 10 via a curved groove 13, four collection boxes 10 for storing water samples being provided inside the limiting box 6, four water inlet holes 7 for introducing water samples into the device being opened on the outer surface of the limiting box 6, an inner tube 17 fixedly connected inside the limiting box 6 to facilitate the up-and-down movement of the limiting box 6, a device body 1 connecting all components being provided on the top of the limiting box 6, a curved groove 13 being opened inside the rotating plate 14, one end of the curved groove 13 being adapted to a water inlet hole 7, and the other end of the curved groove 13 being located at the center of the opening at the upper end of the collection box 10, used to introduce external water into the collection box 10 for sampling water resources, and a second motor 18 being located at the bottom of the device body 1, connected to the device body 1. The main body 1 is fixedly connected, and the output end of the second motor 18 is fixedly connected to a threaded rod 19, which facilitates threaded transmission with the inner tube 17 to drive the limiting box 6 and the inner tube 17 to move up and down. The outer surface of the threaded rod 19 is connected to the internal thread of the inner tube 17, and the internal thread of the inner tube 17 is adapted to the thread on the outer surface of the threaded rod 19. This is used to move the limiting box 6 up and down and insert the limiting box 6 into the water for sampling. The first motor 16 is located on the inner top wall of the limiting box 6, and its output end is fixedly connected to a first gear 15, which facilitates meshing transmission with the second gear 21, through a coupling. The upper surface of the rotating plate 14 is fixedly connected to a second gear 21, which facilitates the rotation of the rotating plate 14. The outer surface of the second gear 21 meshes with the outer surface of the first gear 15, driving the rotating plate 14 to rotate. This is used to adjust the position of the curved groove 13 and to introduce water resource samples at different positions into different collection boxes 10 through the curved groove 13.

[0022] The bottom of the collection box 10 is fixedly connected to a handle 9 for easy downward pulling to remove the collection box 10. The bottom of the limiting box 6 is fixedly connected to a limiting post 12 for limiting the position of the limiting plate 11. The outer surface of the limiting post 12 is fixedly connected to a plate 11 for limiting the position of the collection box 10. The upper surface of the plate 11 is in contact with the lower surface of the collection box 10. The plate 11 abuts against the bottom of the collection box 10 to limit the position of the collection box 10.

[0023] The device body 1 has four blades 2 on its surface to facilitate lifting and lowering of the device. The bottom of each of the four blades 2 is equipped with a float 3 to help the device float on the water surface and protect the device in the event of an accidental fall.

[0024] The device body 1 has two support brackets 4 fixedly connected to its lower surface to support the device, allowing it to rise and fall safely.

[0025] The two brackets 4 are each fixedly connected to a connecting plate 8 for connecting the support bracket 4. The outer surfaces of the two connecting plates 8 are provided with limiting grooves 5 for limiting protrusions 20. The outer surface of the limiting box 6 is fixedly connected to two protrusions 20 for connecting the limiting box 6.

[0027] During operation, the device body 1 is first moved to a position above the water surface to be sampled. Then, the second motor 18 is started, which drives the threaded rod 19 to rotate. The threaded rod 19 engages with the inner tube 17, causing the protrusion 20 to move downward under the limiting action of the limiting groove 5, so that the limiting box 6 is inserted below the water surface. At this time, the first motor 16 is started, driving the first gear 15 to rotate. The first gear 15 engages with the second gear 21, driving the second gear 21 to rotate, which in turn drives the rotating plate 14 to rotate, aligning the curved groove 13 with a water inlet 7. At this time, the end of the curved groove 13 away from the water inlet 7 is located in a collection area. Above the collection box 10, water flows into the collection box 10 through the inlet hole 7 and the curved groove 13. After sampling is completed at this point, the first motor 16 is started again to rotate the rotating plate 14 by 45 degrees to seal the collection box 10 after sampling. Then, the next sampling point is reached, and the first motor 16 is started again to rotate the rotating plate 14 so that the curved groove 13 is aligned with the next collection box 10 and the inlet hole 7. The sampling operation is repeated. After sampling is completed, the locking plate 11 at the bottom of the limiting box 6 is moved to release the limiting plate 11 from the collection box 10. The handle 9 is pulled down to release the collection box 10 from the limiting box 6. The sample in the collection box 10 is stored and labeled to complete the sampling work.

[0028] Although 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 alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
