[0002] Sewage sampling is an important step in the water quality monitoring process, which is used to collect water samples that represent the characteristics of sewage in order to evaluate its chemical, biological and physical properties; UAV sewage sampling is a new, highly automated monitoring method suitable for sewage sample collection in difficult-to-reach or hazardous environments.

[0003] When taking samples, a drone generally flies to a sampling location, and then completes the sampling through a falling sampling bucket. Existing drones generally fly to a sampling location for sampling once, and when the drone returns, it collects the sample in the sampling bucket before flying to another sampling location for the next sampling. Usually, sampling requires taking samples from multiple locations in an area. Each time the drone takes samples at different locations, it needs to return to take the first sample before it can proceed to the next sampling, which is time-consuming and causes a waste of resources.

[0022] It is easy to understand that according to the technical solution of the utility model, without changing the essential spirit of the utility model, a person skilled in the art can propose a variety of interchangeable structural modes and implementation modes. Therefore, the following specific implementation modes and drawings are only exemplary descriptions of the technical solution of the utility model, and should not be regarded as the entirety of the utility model or as a limitation or restriction to the technical solution of the utility model.

[0023] A sewage sampling device based on a drone, such as Figure 1 As shown, it includes a drone body 1, and the bottom end of the drone body 1 is detachably connected to a winding assembly 2, such as Figure 4 As shown, the winding assembly 2 includes a fixed box 21, a winding shaft 22, a winding motor 23, a bolt 24 and a slider 25. A groove 11 is provided at the bottom end of the drone body 1, and a slider 25 is provided at the top of the fixed box 21; the slider 25 is slidably connected to the groove 11, and the fixed box 21 and the drone body 1 are matched with the connecting bolt 24; the internal rotation of the fixed box 21 is connected to the winding shaft 22, and the winding shaft 22 is connected to the winding motor 23; the outer side of the winding shaft 22 is wound with a connecting rope 3; when connecting the winding assembly 2 to the drone body 1, the slider 25 is slid into the groove 11 to realize the preliminary connection between the winding assembly 2 and the drone body 1, and then the fixing is strengthened by the bolt 24; the winding motor 23 drives the winding shaft 22 to rotate and thus drives the connecting rope 3 to be retracted and released.

[0024] The bottom end of the winding assembly 2 is connected to the collection box 4 through a connecting rope 3. Specifically, the top of the collection box 4 is rotatably connected to a handle 41, and the movable end of the connecting rope 3 is fixed to the handle 41. A lifting assembly 5 is provided inside the collection box 4, and the lifting assembly 5 includes a multi-section pneumatic lifting rod 51, a rotating block 52, a spiral groove 53 and a vertical rod 54. Figure 2 and Figure 5 As shown, a vertical rod 54 is fixedly passed through the inside of the collection box 4, and a spiral groove 53 is provided on the surface of the vertical rod 54; the rotating block 52 is sleeved with the vertical rod 54, and the rotating block 52 extends and inserts into the spiral groove 53; a multi-section pneumatic lifting rod 51 is provided at the bottom of the rotating block 52; a push block 8 is fixed on the side of the rotating block 52. The multi-section pneumatic lifting rod 51 can push the rotating block 52 to move upward when it is lifted and lowered, and the rotating block 52 can rotate under the constraint of the spiral groove 53 when it moves upward, thereby driving the push block 8 to rotate synchronously during the upward movement. A movable door can be provided on the side of the collection box 4 to facilitate the sample in the sampling assembly 6 to be pushed out.

[0025] A push block 8 is provided on the side of the lifting component 5; the lifting component 5 is used to drive the push block 8 to rotate and rise and fall, and an opening is provided on the side of the push block 8; a plurality of sampling components 6 are equidistantly fixed in a circular array inside the collecting box 4, and the inlet and outlet ends of the sampling components 6 extend outward from the collecting box 4; each of the sampling components 6 is connected to an operating rod 7 of different heights, and the operating rod 7 is connected to the push block 8 in cooperation; the rising of the operating rod 7 is used to drive the sampling component 6 connected thereto to form a negative pressure to adsorb sewage for sampling.

[0026] The cross-section of the operating rod 7 adopts a "7"-shaped structure, and the operating rod 7 is adapted to the opening opened on the side of the push block 8; when the lifting assembly 5 moves upward, it drives the push block 8 to move upward and rotates at the same time. When the push block 8 moves upward, it drives the operating rod 7 in contact with it to move upward until the push block 8 rotates to its opening to match the operating rod 7, so that the operating rod 7 in contact with it leaks out of the opening, and at this time, the push block 8 can no longer push the operating rod 7 to move upward.

[0027] The sampling assembly 6 includes a container bottle 61, a rubber block 62 and an inlet and outlet pipe 63. Figure 3 As shown, the interior of the container bottle 61 is slidably connected with a rubber block 62, and the rubber block 62 is connected to the operating rod 7; the bottom end of the container bottle 61 is connected to the inlet and outlet pipe 63; the inlet and outlet pipe 63 extends outward from the collecting box 4; the sampling component 6 adopts the principle of a syringe, and when the operating rod 7 moves upward, the rubber block 62 can be pulled to move, and the sewage sample can be sampled through the inlet and outlet pipe 63.

[0028] The implementation case of the present invention is provided with three sampling components 6, and three operating rods 7 are adapted to the sampling components 6. The three sampling components 6 are fixed in the cylindrical collecting box 4 in a ring array; the heights of the operating rods 7 respectively connected to the three sampling components 6 are increased in sequence; the height to which the three operating rods 7 are increased is the same as the height to which the rotating block 52 increases after one rotation; that is, after pushing another operating rod 7 to a suitable height, the pushing block 8 can contact the operating rod 7 of the second height, and the operating rod 7 of the second height can be increased.

[0029] When the utility model is in use, the drone body 1 is first driven to move the entire drone to a location where sampling is required, and after the sampling location is determined, the winding motor 23 is started. When the winding motor 23 is started, the winding shaft 22 is driven to rotate, so that the connecting rope 3 is extended and the collecting box 4 is driven to enter the location where sampling is required, and then the multi-section pneumatic lifting rod 51 is started, and the multi-section pneumatic lifting rod 51 rises, pushing the rotating block 52 to rise. At the same time, the rotating block 52 rotates around the spiral groove 53 under the restriction of the spiral groove 53, so that the bottom operating rod 7 moves up, and the sampling assembly 6 adapted to the bottom operating rod 7 is used to take samples; the pushing block 8 moves up And rotate one circle, so that the operating rod 7 at the bottom is separated from the pushing block 8, that is, the sampling of the first sampling component 6 is completed; after arriving at the next sampling location, the multi-section pneumatic lifting rod 51 is then started again, and the multi-section pneumatic lifting rod 51 continues to rise, pushing the rotating block 52 to rise. At the same time, the rotating block 52 rotates around the spiral groove 53 under the restriction of the spiral groove 53, thereby moving the operating rod 7 at the second height upward, and sampling is performed using the sampling component 6 compatible with the operating rod 7 at the second height; the pushing block 8 moves upward and rotates one circle, so that the operating rod 7 at the second height is separated from the pushing block 8; based on this, the sampling of the three sampling components 6 is completed.
