Description

Technical Field

[0001] The utility model relates to the technical field of water environment detection, and particularly relates to a floating water environment detection device. Background Art

[0002] In the fields of environmental science research and water quality monitoring, as an important automated sampling tool, the floating water environment sampling remote control boat has been widely used in waters such as lakes, rivers, and reservoirs. With the advantages of no need for direct manual operation and the ability to sample deep in the center of the water area, this type of remote control boat has greatly improved the safety and efficiency of sampling. However, despite certain progress in the existing technology, there are still significant limitations in multi-position continuous sampling and sample management, specifically manifested as follows: when the existing floating water environment sampling remote control boat performs a sampling task, after completing one sampling, the remote control boat often needs to return to the shore, and the operator takes out the sample in the sampling tube and replaces the sampling tube again before it can set off for the next sampling point. This "departure - sampling - return - replacing the sampling tube - departure again" mode not only greatly reduces the sampling efficiency but also increases the time and labor costs. Summary of the Utility Model

[0003] The technical problem to be solved by the utility model is to provide a floating water environment detection device to overcome the above deficiencies in the existing technology.

[0004] The technical solution of the utility model to solve the above technical problem is as follows: a floating water environment detection device includes a remote control boat body and a sampling system; the sampling system is arranged in the cabin of the remote control boat body, and the sampling system includes a turntable mechanism and a water pumping mechanism. A number of sampling tubes are arranged in a circumferential array on the turntable mechanism, and the water outlet end of the water pumping mechanism is arranged above the sampling tube.

[0005] The beneficial effect of the utility model is that: through the water pumping mechanism for sampling water body samples, when the sampling tube collects the water body samples at this position, the remote control boat body goes to the next sampling point, and through the turntable mechanism, the position of the sampling tube is adjusted to make the empty sampling tube located below the water outlet end of the water pumping mechanism for re-sampling at the new sampling point. This device can separately pack the water body samples at different sampling points in different sampling tubes, and there is no need to frequently return to the shore due to replacing the sampling tube during the sampling process. During one trip, the sampling at multiple sampling points can be completed, which can greatly improve the sampling efficiency.

[0006] On the basis of the above technical solution, the utility model can also be improved as follows.

[0007] Further, the sampling system further includes a telescopic mechanism. The water outlet end of the water pumping mechanism is communicated with a hollow spike part, the spike part is arranged at the telescopic end of the telescopic mechanism, and a rubber plug is hermetically arranged at the pipe orifice part of the sampling tube.

[0008] Further, the telescopic mechanism includes a lifting rod and a top plate arranged at the telescopic end of the lifting rod. The water outlet end of the water pumping mechanism is downwardly arranged on the top plate, and the spike portion penetrates through the top plate and extends vertically downward.

[0009] Further, the telescopic mechanism further includes an optical axis, which is arranged along the lifting direction of the lifting rod. The top plate is sleeved on the optical axis and moves along the length direction of the optical axis.

[0010] Further, a limit seat is arranged on the optical axis, and a limit switch is arranged on the upper end surface of the limit seat.

[0011] Further, the water pumping mechanism includes a water pump, and a water inlet pipe and a water outlet pipe respectively connected to the water inlet end and the water outlet end of the water pump.

[0021] The principles and features of the present utility model will be described below in conjunction with the accompanying drawings. The examples given are only used to explain the present utility model and are not intended to limit the scope of the present utility model.

[0022] As Figures 1 to 4 shown, in Embodiment 1, a floating water environment detection device includes a remote control boat body 1 and a sampling system 2; the sampling system 2 is arranged in the cabin of the remote control boat body 1. The sampling system 2 includes a turntable mechanism 21 and a water pumping mechanism 22. A number of sampling tubes 3 are arranged in a circumferential array on the turntable mechanism 21. For example, in a specific implementation, 10 sampling tubes 3 are arranged in an equiangular circumferential array at an angle of 36°. The water outlet end of the water pumping mechanism 22 is arranged above the sampling tube 3.

[0023] The water body sample is sampled through the water pumping mechanism 22. After the sampling tube 3 collects the water body sample at this position, the remote control boat body 1 goes to the next sampling point. The position of the sampling tube 3 is adjusted through the turntable mechanism 21, so that the empty sampling tube 3 is located below the water outlet end of the water pumping mechanism 22, and a new sampling point is resampled. This device can separately pack the water body samples at different sampling points in different sampling tubes 3. During the sampling process, there is no need to frequently return to the shore due to the replacement of the sampling tube. During one trip, the sampling of multiple sampling points can be completed, which can greatly improve the sampling efficiency.

[0024] Embodiment 2 is a further improvement based on Embodiment 1, which is specifically as follows:

[0025] The sampling system 2 further includes a telescopic mechanism 23. The water outlet end of the water pumping mechanism 22 is communicated with a hollow spike part 221. The spike part 221 is arranged at the telescopic end of the telescopic mechanism 23. A rubber plug 31 is hermetically arranged at the pipe orifice part of the sampling tube 3.

[0026] The telescopic mechanism 23 drives the spike part 221 to pierce through the rubber plug 31, and then the water body sample can be injected into the sampling tube 3. After the sampling is completed, the spike part 221 disengages from the rubber plug 31. Under the elastic action of the rubber plug 31, the punctured needle hole closes, which can prevent the water body sample in the sampling tube 3 from overflowing during the driving process of the remote control boat.

[0027] Embodiment 3 is a further improvement based on Embodiment 2, which is specifically as follows:

[0028] The telescopic mechanism 23 includes a lifting rod 231 and a top plate 232 arranged at the telescopic end of the lifting rod 231. The water outlet end of the water pumping mechanism 22 is arranged downward on the top plate 232, and the spike part 221 penetrates through the top plate 232 and extends vertically downward. In a specific implementation, the lifting rod 231 can be an electric push rod, a hydraulic push rod or a pneumatic push rod.

[0029] Example 4. This example is a further improvement based on Example 3, and the details are as follows:

[0030] The telescopic mechanism 23 further includes a optical axis 233. The optical axis 233 is arranged along the lifting direction of the lifting rod 231. The top plate 232 is sleeved on the optical axis 233 and moves along the length direction of the optical axis 233, enabling the top plate 232 to move stably up and down on the optical axis 233.

[0031] Example 5. This example is a further improvement based on Example 4, and the details are as follows:

[0032] A limit seat 234 is arranged on the optical axis 233, and a limit switch 235 is arranged on the upper end face of the limit seat 234. The limit switch 235 can limit the lifting height of the lifting rod 231, enabling the spike part 221 to just extend into the sampling tube 3 before injecting the water sample.

[0033] Example 6. This example is a further improvement based on Example 2, and the details are as follows:

[0034] The pumping mechanism 22 includes a water pump 222, and a water inlet pipe 223 and a water outlet pipe 224 respectively connected to the water inlet end and the water outlet end of the water pump 222. The water inlet end of the water inlet pipe 223 extends downward from the bottom of the cabin of the remote control boat body 1, and the spike part 221 is connected to the water outlet end of the water outlet pipe 224.

[0035] Example 7. This example is a further improvement based on Example 6, and the details are as follows:

[0036] The pumping mechanism 22 further includes a filter cover 225 arranged at the bottom of the remote control boat. The water inlet end of the water inlet pipe 223 is arranged inside the filter cover 225. The filter cover 225 can filter out large-particle floating objects on the water surface and prevent the water pump 222 from being blocked.

[0037] Example 8. This example is a further improvement based on Example 1, and the details are as follows:

[0038] The turntable mechanism 21 includes a turntable seat 211 and a motor 212. A number of placement grooves 2111 for placing the sampling tubes 3 are arranged on the turntable seat 211. The motor 212 is arranged at the bottom of the turntable seat 211, and the rotating shaft of the motor 212 is connected to the bottom of the turntable seat 211. In specific implementation, the motor 212 adopts a stepping motor, and the rotation angle is more accurate, enabling the spike part 221 to just correspond to the position of the sampling tube 3 during each rotation of the turntable mechanism 21.

[0039] Example 9. This example is a further improvement based on Example 8, and the details are as follows:

[0040] A receiving cavity 2112 is provided in the middle and lower part of the turntable base 211, and the motor 212 is arranged in the receiving cavity 2112. This enables the motor 212 to be hidden in the turntable base 211, reducing the overall volume and height of the remote control boat.

[0041] Although the embodiments of the present invention have been shown and described above, it can be understood that the above embodiments are exemplary and should not be construed as limiting the present invention. Those of ordinary skill in the art can make changes, modifications, substitutions, and variations to the above embodiments within the scope of the present invention.
