[0025] The technical solution of this patent will be further described in detail below with reference to specific embodiments.

[0026] like Figure 1-3As shown, this utility model provides a technical solution: a drone water collection device, including a body 1, with several arms 4 fixedly connected to the outer surface of the body 1. Several blades are rotatably mounted on one end of each arm 4. A rope take-up device 5 and a hanging rope 6 are provided at the bottom of the body 1. The rope take-up device 5 contains a drive motor and a drum for winding the hanging rope 6. One end of the hanging rope 6 is fixed inside the rope take-up device 5. The end of the hanging rope 6 away from the rope take-up device 5 is bolted to a connecting rod 7. A water box 8 is bolted to the bottom of the connecting rod 7. A filter screen 9 is installed on the top of the water box 8 using a convenient device 3. A positioning device 2 is provided at the bottom of the rope take-up device 5. The positioning device 2 includes two grooved rods 21, the tops of which are connected to... The bottom end of the rope retractor 5 is fixedly connected, and a sliding rod 22 is slidably connected to the inner wall of the groove rod 21. A cylinder 23 is fixedly connected to the bottom end of the sliding rod 22. The inner diameter of the cylinder 23 is slightly larger than the diameter of the suspension rope 6. By setting the cylinder 23, when using the drone water collection device, the bottom end of the suspension rope 6 is passed through the inside of the cylinder 23 at the bottom end of the sliding rod 22. Then, the bottom end of the suspension rope 6 is inserted into the hole at the top end of the connecting rod 7. The suspension rope 6 is connected to the connecting rod 7 by inserting a bolt. The filter screen 9 is installed on the top of the water box 8 through the convenient device 3. Then, the top end of the water box 8 is attached to the bottom end of the connecting rod 7. The water box 8 is connected to the connecting rod 7 by bolts. The specific connection steps of the connecting rod 7, suspension rope 6 and water box 8 of the drone water collection device are as follows. All steps are well-known to those skilled in the art and will not be elaborated here. Then, the drone is controlled by a remote control device to fly to the water source via the rotating propeller at one end of arm 4. The rope retractor 5 is operated, controlling the internal drive motor to rotate the drum, releasing the suspension rope 6 from the drum surface and lowering the water box 8 into the water area. Water from the water area enters the water box 8 through the filter screen 9 at the top. Then, the rope retractor 5 is operated again to raise the suspension rope 6, causing the water box 8 to rise. During the ascent of the water box 8, the top of the connecting rod 7 contacts the bottom of the cylinder 23, pushing the sliding rod 22 upwards along the inner wall of the groove rod 21. The bottom of the cylinder 23 rests against the top of the connecting rod 7, restricting the position of the connecting rod 7 and the water box 8. The movable rod 22 and the grooved rod 21 limit the angle between the cylinder 23 and the body 1, so as to avoid the linkage 7 and the water box 8 from shaking during the flight of the drone. After the drone returns, the water box 8 can be removed from the linkage 7 to obtain the water sample. By setting the positioning device 2, when the water box 8 is controlled to rise and approach the body 1 after water is taken, the top of the linkage 7 will abut against the bottom of the cylinder 23 to limit the position of the linkage 7 and the water box 8. The sliding rod 22 and the grooved rod 21 limit the angle between the cylinder 23 and the body 1, so as to avoid the linkage 7 and the water box 8 from shaking during the flight of the drone, which would affect the normal flight of the drone and cause the water sample inside the water box 8 to leak.

[0027] Specifically, such as Figure 2 and Figure 3As shown, a circular block 24 is fixedly connected to the bottom end of the cylinder 23. The diameter of the circular block 24 is about 5 to 6 times the diameter of the cylinder 23. When the water box 8 and the connecting rod 7 rise, the top of the connecting rod 7 rests against the bottom end of the circular block 24, which more stably restricts the position of the connecting rod 7 and makes the connecting rod 7 and the water box 8 less likely to shake. A gasket 26 is fixedly connected to the bottom end of the circular block 24. The gasket 26 is a rubber sheet made of rubber. By setting the rubber gasket 26 at the bottom end of the circular block 24 to contact the top end of the connecting rod 7, the fit is tighter and the connecting rod 7 is less likely to shake.

[0028] Specifically, such as Figure 2 and Figure 3 As shown, two rotating wheels 25 are rotatably connected to both ends of the sliding rod 22. The rotating wheels 25 move on the outer surface of the groove rod 21. When the sliding rod 22 slides upward on the inner wall of the groove rod 21, the rotating wheels 25 at both ends will move on the outer surface of the groove rod 21. The rotating wheels 25 can further limit the angle between the sliding rod 22 and the groove rod 21, and avoid the angle of the sliding rod 22 from deflecting as much as possible, thus improving the stability of the sliding rod 22 when it moves. Two first springs 27 are provided at the top of the inner wall of the groove rod 21, and a stop bar 28 is provided at the bottom of the two first springs 27. The upper and lower ends of the spring 27 are fixedly connected to the top of the inner wall of the groove rod 21 and the top of the stop rod 28, respectively. The stop rod 28 slides on the inner wall of the groove rod 21. When the sliding rod 22 moves upward and is about to contact the top of the groove rod 21, it will contact the bottom of the stop rod 28. Then the sliding rod 22 continues to move, which will push the stop rod 28 to move and compress the first spring 27. The thrust of the first spring 27 further buffers the movement of the sliding rod 22, the hanging rope 6 and the water box 8, and avoids the sliding rod 22 moving too fast and contacting the top of the groove rod 21, causing shaking and spilling the water sample inside the water box 8.

[0029] Specifically, such as Figure 1 and Figure 4As shown, the convenient device 3 includes two locking blocks 35, which are fixedly connected to both sides of the filter screen 9. Rectangular grooves 31 are formed on both sides of the top of the water box 8. A sliding groove 32 is formed on one side of the inner wall of the rectangular groove 31. A slider 34 is slidably connected to the inner wall of the sliding groove 32. A second spring 33 is provided at one end of the slider 34. The two ends of the second spring 33 are fixedly connected to one end of the inner wall of the sliding groove 32 and one end of the slider 34, respectively. When installing the filter screen 9, align the filter screen 9 with the top of the water box 8, and then insert the locking blocks 35 at both ends of the filter screen 9 into the two rectangular grooves 31 at the top of the water box 8, so that the locking blocks 35... The bottom end of 5 contacts the top end of slider 34. Pressing down the filter screen 9 pushes slider 34 into the slide groove 32 through the locking block 35 and compresses the second spring 33, so that the bottom end of the locking block 35 contacts the bottom end of the inner wall of the rectangular groove 31. Then the second spring 33 returns to its original state and pushes slider 34 outward to above the locking block 35, fixing the locking block 35 in the rectangular groove 31 and fixing filter screen 9 to the top of water box 8. When it is necessary to clean filter screen 9, slider 34 can be pushed at the two rectangular grooves 31 to move slider 34 into the slide groove 32, and then filter screen 9 can be pulled to make locking block 35 disengage from rectangular groove 31 to remove filter screen 9.

[0030] Specifically, such as Figure 1 and Figure 4 As shown, an auxiliary piece 36 is fixedly connected to one side of the top of the slider 34. The top edge of the auxiliary piece 36 is arc-shaped. The bottom of the locking block 35 contacts the surface of the arc-shaped auxiliary piece 36 at one end of the slider 34, making it easier to push the slider 34 to move and less likely to jam against each other.

[0031] The working principle of this utility model is as follows:

[0032] S1. When using the drone water collection device, pass the bottom end of the suspension rope 6 through the inside of the cylinder 23 at the bottom of the sliding rod 22, then insert the bottom end of the suspension rope 6 into the hole at the top of the connecting rod 7. Use a bolt to connect the suspension rope 6 to the connecting rod 7. Align the filter screen 9 with the top of the water box 8. Then insert the locking blocks 35 at both ends of the filter screen 9 into the two rectangular slots 31 at the top of the water box 8, so that the bottom end of the locking block 35 contacts the top of the slider 34. Press down on the filter screen 9 to allow it to pass through. The locking block 35 pushes the slider 34 into the groove 32 and compresses the second spring 33, causing the bottom end of the locking block 35 to contact the bottom end of the inner wall of the rectangular groove 31. Then, the second spring 33 returns to its original state and pushes the slider 34 outward to above the locking block 35, fixing the locking block 35 in the rectangular groove 31 and the filter screen 9 to the top of the water box 8. Then, the top end of the water box 8 is attached to the bottom end of the connecting rod 7, and the water box 8 is connected to the connecting rod 7 of the drone water collection device and the suspension rope 6 by bolts. The specific connection steps of the water box 8 are well known to those skilled in the art and will not be elaborated here. Then, the drone is controlled by the remote control device to fly to the water source by rotating the propeller at one end of the arm 4. The rope take-up device 5 is operated to control the drive motor inside the rope take-up device 5 to drive the rotating drum to rotate, and the suspension rope 6 on the surface of the rotating drum is released to lower the water box 8 into the water area. The water in the water area will enter the water box 8 through the filter screen 9 at the top of the water box 8. Then, the rope take-up device 5 is operated again to control the suspension rope 6 to rise, which will drive the water box 8 to rise. During the rise of the water box 8, the top of the connecting rod 7 contacts the bottom of the cylinder 23, which will push the sliding rod 22 to slide upward on the inner wall of the groove rod 21. The bottom of the cylinder 23 abuts against the top of the connecting rod 7 to restrict the position of the connecting rod 7 and the water box 8. The angle between the cylinder 23 and the body 1 is restricted by the sliding rod 22 and the groove rod 21 to minimize the shaking of the connecting rod 7 and the water box 8 during the drone's flight. After the drone flies back, the water box 8 can be removed from the connecting rod 7 to obtain the water sample.

[0033] S2. When the filter screen 9 needs to be cleaned, the slider 34 can be pushed at the two rectangular grooves 31 to move the slider 34 into the groove 32, and then the filter screen 9 can be pulled to make the locking block 35 disengage from the rectangular groove 31 and the filter screen 9 can be removed.
