[0021] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0022] Embodiment 1

[0023] As Figure 1 shown:

[0024] A water sample sampling device for hydrological measurement includes a housing seat 1.

[0025] In this implementation: To solve the technical problems existing in this prior art, such as those disclosed in the background art above, "Most of the current existing water quality sampling devices sample manually, directly taking a sampling bottle to the middle of the lake to collect water. Because it is often necessary to sample in deep water areas, this water sample sampling method is relatively dangerous for the staff and has a low sampling efficiency." In combination, this problem is obviously a real and relatively difficult problem to solve. In view of this, to solve this technical problem, a sampling assembly 2 is added to this application document.

[0026] Furthermore:

[0027] As Figures 1-4 shown:

[0028] A sampling assembly 2 is installed on the housing base 1. The sampling assembly 2 includes a drone main body 201 fixed on the upper surface of the housing base 1, a driving motor 202 installed on the inner side wall of the housing base 1 by bolts, and a rotating rod 203 fixed to the output end of the driving motor 202. A winding rod 204 is fixed on the surface of the rotating rod 203, and a rope 205 is wound around the surface of the winding rod 204. One end of the rope 205 is fixed with a chassis 206. A placement hole is reserved at the bottom of the housing base 1 for the vertical movement of the rope 205 to pass through. A plurality of sampling cylinders 207 arranged in an annular and equidistant manner are provided below the chassis 206. A water inlet 208 is formed on the surface of the sampling cylinder 207. The other end of the rotating rod 203 is rotatably connected to the housing base 1 through a bearing, and the other end of the rope 205 is fixed to the winding rod 204.

[0029] In this embodiment: When this water sample sampling device for hydrological measurement is in use, the drone main body 201 drives the whole to fly to the water area to be sampled. Subsequently, by starting the driving motor 202, the rotating rod 203 is driven to rotate. Through the rotation of the rotating rod 203, the winding rod 204 is driven to rotate. The rope 205 is released by the winding rod 204, so that the chassis 206 and the sampling cylinder 207 are synchronously lowered until the sampling cylinder 207 penetrates into the water, enabling the water to be sampled to enter the interior of the sampling cylinder 207 through the water inlet 208 to complete the sampling. Through this operation, sampling can be carried out at any position of the water area without manual sampling, reducing the labor intensity of the staff and improving work efficiency. Moreover, the danger of manual sampling can be avoided during sampling, improving the use effect of the device.

[0030] It should be noted that: The driving motor 202 is controlled by remote control. The remote control signal is converted into a signal recognizable by the driving motor 202, thereby realizing the control of the driving motor 202. The power supply of the driving motor 202 is provided by the power supply of the drone main body 201 itself.

[0031] Furthermore;

[0032] In an optional embodiment, telescopic rods 221 arranged symmetrically are fixed between the chassis 206 and the housing base 1.

[0033] In this embodiment: While the chassis 206 is lowered, the telescopic rods 221 are stretched. Through the arrangement of the telescopic rods 221, the chassis 206 can be limited, making the process of the chassis 206 being lowered more stable and not easily affected by wind, so as to avoid tilting during the lowering process of the chassis 206.

[0034] Furthermore;

[0035] In an alternative embodiment, a camera 209 is fixedly installed on the lower surface of the housing base 1.

[0036] In this embodiment: Through the setting of the camera 209, the downward movement state of the sampling cylinder 207 driven by the chassis 206 can be observed in real time, providing a better use effect for sampling.

[0037] It should be noted that: The camera 209 transmits the real-time image to a remote control screen (not shown in the figure) for display through a signal.

[0038] Furthermore;

[0039] In an alternative embodiment, an installation sleeve 210 is arranged inside the sampling cylinder 207. A storage battery 211 is fixedly installed inside the installation sleeve 210. A sealing ring 212 is fixed on the outer surface of the installation sleeve 210. The outer surface of the sealing ring 212 is fitted with the inner side wall of the sampling cylinder 207. An electromagnet sheet two 214 is fixedly installed on the upper surface of the sampling cylinder 207. An electromagnet sheet one 213 is fixed on one side of the surface of the installation sleeve 210 close to the electromagnet sheet two 214. The electromagnet sheet one 213 and the electromagnet sheet two 214 are fitted together. Symmetrically arranged L-shaped connecting brackets 215 are fixed on the surface of the installation sleeve 210. An electromagnet sheet four 217 is fixed between the surfaces of the two groups of L-shaped connecting brackets 215. The electromagnet sheet four 217 is sleeved outside the sampling cylinder 207. An electromagnet sheet three 216 is fixed on one side of the surface of the sampling cylinder 207 close to the electromagnet sheet four 217. The electromagnet sheet one 213 is located above the electromagnet sheet two 214. The electromagnet sheet three 216 is located above the electromagnet sheet four 217. The bottom diameter of the installation sleeve 210 is larger than the inner diameter of the top opening of the sampling cylinder 207.

[0040] In this embodiment: When sampling, when multiple sampling cylinders 207 are all in water, the storage battery 211 is used to energize the first electromagnet piece 213 and the second electromagnet piece 214. The first electromagnet piece 213 and the second electromagnet piece 214 are designed with the same poles, and the generated magnetic forces repel each other. Subsequently, the first electromagnet piece 213 and the second electromagnet piece 214 separate and drive the sampling cylinder 207 to move downward. At this time, the sampling cylinder 207 separates from the surface of the sealing ring 212. At this time, the third electromagnet piece 216 and the fourth electromagnet piece 217 are in contact with each other, thereby releasing the blockage of the water inlet 208. At this time, the sampled water enters the interior of the sampling cylinder 207 through the water inlet 208. When the sampling is completed, the first electromagnet piece 213 and the second electromagnet piece 214 are de-energized, and at the same time, the fourth electromagnet piece 217 and the third electromagnet piece 216 are energized. Through the same-direction magnetic poles of the fourth electromagnet piece 217 and the third electromagnet piece 216, they repel each other and drive the sampling cylinder 207 to move upward until the water inlet 208 of the sampling cylinder 207 is located at the position of the sealing ring 212, and the water inlet 208 is blocked again. Through this operation, multiple sampling cylinders 207 can sample multiple different water areas, further improving the practicability and flexibility of the device.

[0041] It should be noted that: The first electromagnet piece 213 and the second electromagnet piece 214 have the same poles, and the fourth electromagnet piece 217 and the third electromagnet piece 216 have the same poles.

[0042] Furthermore;

[0043] In an alternative embodiment, a plug post 218 is fixed on the upper surface of the mounting sleeve 210. Symmetrically arranged locking pins 219 are slidably connected inside the plug post 218. A spring 220 is fixed between the locking pins 219 and the plug post 218. A moving groove adapted to the locking pins 219 is formed on the surface of the plug post 218. The locking pins 219 and the plug post 218 are slidably connected through this moving groove. Card slots adapted to the mounting sleeve 210 and the plug post 218 are respectively formed inside the chassis 206.

[0044] In this embodiment: When disassembling the sampling cylinder 207 and the mounting sleeve 210, by pressing the locking pins 219 and compressing the spring 220 until the locking pins 219 completely move into the interior of the plug post 218, the plug post 218 is disengaged from the chassis 206, thereby completing the disassembly of the entire sampling cylinder 207 and the mounting sleeve 210. The third electromagnet piece 216 and the fourth electromagnet piece 217 are de-energized, and then the sampled water can be poured out from the water inlet 208.

[0045] Working principle and usage process of the present utility model: When using this water sample sampling device for hydrological measurement, the drone main body 201 drives the whole to fly to the water area to be sampled. Subsequently, by starting the drive motor 202, the rotating rod 203 is driven to rotate. Through the rotation of the rotating rod 203, the winding rod 204 is driven to rotate. The rope 205 is released by the winding rod 204, and then the chassis 206 and the sampling cylinder 207 are synchronously lowered until the sampling cylinder 207 penetrates into the water. While the chassis 206 is lowered, the telescopic rod 221 is stretched. Through the setting of the telescopic rod 221, the chassis 206 can be limited, making the chassis 206 more stable during the lowering process and not easily affected by wind, so as to avoid tilting during the lowering process of the chassis 206. Through the setting of the camera 209, the state of the chassis 206 driving the sampling cylinder 207 to lower can be observed in real time, providing a better usage effect for sampling. When sampling, when multiple sampling cylinders 207 are all in the water, the battery 211 is used to energize the electromagnet sheet one 213 and the electromagnet sheet two 214. The electromagnet sheet one 213 and the electromagnet sheet two 214 are designed with the same poles, and the generated magnetic forces repel each other. Subsequently, the electromagnet sheet one 213 and the electromagnet sheet two 214 are separated, driving the sampling cylinder 207 to lower. At this time, the sampling cylinder 207 is separated from the surface of the sealing ring 212. At this time, the electromagnet sheet three 216 and the electromagnet sheet four 217 are attached to each other, thus releasing the blockage of the water inlet 208. At this time, the sampled water enters the inside of the sampling cylinder 207 through the water inlet 208. When sampling is completed, the electromagnet sheet one 213 and the electromagnet sheet two 214 are powered off, and at the same time, the electromagnet sheet four 217 and the electromagnet sheet three 216 are energized. Through the same-direction magnetic poles of the electromagnet sheet four 217 and the electromagnet sheet three 216, they repel each other and drive the sampling cylinder 207 to rise until the water inlet 208 of the sampling cylinder 207 is located at the position of the sealing ring 212, and the water inlet 208 is blocked again. Through this operation, multiple sampling cylinders 207 can sample multiple different water areas, further improving the practicability and flexibility of the device. When disassembling the sampling cylinder 207 and the mounting sleeve 210, by pressing the locking pin 219 and compressing the spring 220 until the locking pin 219 completely moves into the insertion post 218, the insertion post 218 is detached from the chassis 206, thus completing the disassembly of the whole sampling cylinder 207 and the mounting sleeve 210. The electromagnet sheet three 216 and the electromagnet sheet four 217 are powered off, and then the sampled water can be poured out from the water inlet 208.

[0046] Finally, it should be noted that the above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or perform equivalent replacements for some of the technical features.
