[0018] Two implementation modes of the present application are described in detail below with reference to the accompanying drawings.

[0019] The first implementation method: Figure 1-Figure 7The present invention shows a water quality monitoring device for a wildlife type nature reserve, which includes a monitoring box 1, a sampling box 2, a disturbance detection mechanism and a water quality monitoring intelligent controller; the monitoring box 1 is connected to the mounting surface through a mounting frame 3, and by mounting the monitoring box 1 above the water surface, it is convenient to monitor the water quality of the water body at any time, and a driving part and an electric winch assembly are installed in the monitoring box 1, and the monitoring box 1 can protect the internal components from damage; a sampling tube 9 is connected to the side of the sampling box 2, and a solenoid valve 11 is installed on the sampling tube 9, and a hose 7 is connected to the top of the sampling box 2, and the top of the hose 7 is placed in the monitoring box 1. The inner cavity of the sampling box 2 is circumferentially distributed with a plurality of collecting barrels 16, the top of each collecting barrel 16 is provided with a through hole 18 corresponding to the bottom end of the hose 7, and the side of each collecting barrel 16 is provided with a through hole 2 17 corresponding to the sampling tube 9, a rope 8 connected to the output end of the electric winch assembly is fixed on the top of the sampling box 2, a driving rod 4 connected to the output end of the driving member is vertically inserted in the middle of the sampling box 2, and a plurality of transposition clips 19 that are clamped with the collecting barrel 16 are fixed at the bottom end of the driving rod 4, the inner cavity of the collecting barrel 16 is vertically slidably connected with a piston plate 23, and the top of the inner cavity of the collecting barrel 16 A push switch 27 is installed, a floating plate 5 is sleeved on the driving rod 4, and a distance sensor 6 is installed at the bottom of the floating plate 5. The rope 8 is extended and shortened by the electric winch assembly to put the sampling box 2 into the specified depth of the water body. Since the water height is different in different seasons, the floating plate 5 is set so that the floating plate 5 is always floating on the water surface. At this time, the distance sensor 6 at the bottom of the floating plate 5 can detect the descending depth of the sampling box 2, and then accurately measure the depth of the sampling box 2 entering the water body. When sampling, the water enters the inner cavity of the collection bucket 16 from the through hole 17 through the sampling tube 9, and the water pressure pushes The piston plate 23 moves upward to push up the air on the top of the collecting barrel 16, and discharges it into the inner cavity of the monitoring box 1 and the external environment through the hose 7. When sampling, the air in the collecting barrel 16 is not discharged from the second through hole 17, thereby reducing the impact on the water body at this depth, reducing the mixing of water bodies at different depths, and improving the sampling accuracy. The driving rod 4 is driven to rotate by the driving member, and drives multiple shifting clamps 19 and the collecting barrel 16 to rotate synchronously, and the multiple collecting barrels 16 are moved to the sampling tube 9 in turn for sampling respectively, and the sampling box 2 is put into different depths to sample water bodies at different depths.

[0020] Also, see Figure 2 and Figure 6 The disturbance detection mechanism includes a detection shaft 14 rotatably connected to the bottom of the sampling box 2, and a disturbance detection plate 10 installed on the detection shaft 14. A torque sensor 31 is installed at the connection between the detection shaft 14 and the sampling box 2. When the sampling box 2 is put into the water body, the disturbed water body will repeatedly impact the disturbance detection plate 10 and drive the detection shaft 14 to rotate forward and backward. The torque sensor 31 can detect the rotation state of the detection shaft 14, thereby understanding the water disturbance situation.

[0021] It is worth mentioning that the water quality monitoring intelligent controller is installed in the monitoring box 1. The water quality monitoring intelligent controller is provided with a command module, an intelligent master control module, a depth control module, a sampling module and a disturbance detection module. The intelligent master control module is electrically connected to the command module, the depth control module, the sampling module and the disturbance detection module respectively. The depth control module is electrically connected to the distance sensor 6 and the electric winch assembly respectively. The sampling module is electrically connected to the solenoid valve 11, the push switch 27 and the driving member respectively. The disturbance detection module is electrically connected to the torque sensor 31. By inputting the sampling time and the water sampling depth into the command module, when sampling is performed, the command module sends a sampling signal to the intelligent master control module, and the intelligent master control module controls the depth control module to lower the sampling box 2 to At a specified depth, the depth control module controls the electric winch assembly to work and synchronously controls the sampling box 2 to descend into the water body through the rope 8. The distance sensor 6 detects the distance data between it and the sampling box 2 and feeds it back to the depth control module. When the depth control module receives the distance data from the distance sensor 6 and reaches the preset depth, it controls the electric winch assembly to stop working and feeds back the result to the intelligent master control module. In this process, the water flow impacts the spoiler detection plate 10 and pushes the detection shaft 14 to rotate forward and reverse repeatedly. The torque sensor 31 receives the torque data of the detection shaft 14 and sends it to the spoiler detection module. When the spoiler detection module detects that the torque data repeatedly fluctuates greatly (greater than the reasonable fluctuation range preset by the spoiler detection module), it is judged that the water body is unstable and is in a mixed state. state, and feeds back a signal that cannot be sampled to the intelligent master control module; when the disturbance detection module detects that the torque data repeatedly fluctuates slightly (within the reasonable fluctuation range preset by the disturbance detection module), it is judged that the water body is in a stable state, and the water bodies of different water depths tend to be stable, and feeds back a signal that can be sampled to the intelligent master control module. At this time, the intelligent master control module sends a sampling signal to the sampling module, and the sampling module controls the driving part to work. The driving part controls the collection barrel 16 to move to the sampling tube 9 in turn through the driving rod 4 and the transposition clamp 19, and controls the solenoid valve 11 to open. The water enters the bottom of the collection barrel 16 through the sampling tube 9 and the through hole 2 17, and the gas in the collection barrel 16 is discharged into the air through the through hole 18 and the hose 7 to reduce the mixing of the water body. During the upward movement of the piston plate 23, it contacts the push switch 27. At this time, the collection bucket 16 is filled with sampled water. The sampling module determines that the collection bucket 16 is full by receiving the feedback signal of the push switch 27 and feeds back the full load signal to the intelligent master control module. The intelligent master control module repeats the sampling of the water at the next depth through the depth control module. After the sampling is completed, the intelligent master control module sends a reset signal to the depth control module. The depth control module controls the corresponding sampling box 2 to move up and reset, thereby realizing automatic sampling of water at different depths, and judging the disturbance of the water at this depth during sampling. The water at different depths is sampled when it tends to be stable. It is not easy to disturb the water at this depth during the sampling process, thereby improving the accuracy of water sampling.

[0022] Also, see Figure 4 , Figure 5 and Figure 7 , an elastic block 20 is arranged in the middle of each transposition clamp 19, a top block 21 is fixed at the position corresponding to the inner cavity of the sampling box 2 and the sampling tube 9, and the top of the top block 21 corresponds to the bottom position of the elastic block 20, a pressure sensor 22 is installed at the bottom of the top block 21, and the sampling module is electrically connected to the pressure sensor 22. When the transposition clamp 19 drives the corresponding collection bucket 16 to move to the sampling tube 9, the elastic block 20 on the transposition clamp 19 contacts the top of the top block 21, and the top of the top block 21 expands the elastic block 20 of the elastic material, so that the transposition clamp 19 extends and pushes the collection bucket 16 close to the sampling tube 9, so the through hole 17 will be close to the end of the sampling tube 9 to improve the airtightness, and when the top block 21 is squeezed by the elastic block 20, the pressure sensor 22 will feed back the received pressure signal to the sampling module, and the sampling module can accurately judge that the collection bucket 16 moves to the position corresponding to the sampling tube 9, which is convenient for sampling operation.

[0023] In this implementation, see Figure 1 and Figure 2 A pressure sensor 2 15 is installed at the bottom of the monitoring box 1 corresponding to the floating plate 5, and an audible and visual alarm component 12 and an infrared sensor 13 are installed on the top of the monitoring box 1. An alarm module electrically connected to the intelligent master control module is also provided on the water quality monitoring intelligent controller. The alarm module is electrically connected to the audible and visual alarm component 12, the infrared sensor 13 and the pressure sensor 2 15 respectively. By setting the alarm module, when the sampling is completed and the depth control module controls the sampling box 2 to reset, the sampling box 2 moves up to push the floating plate 5 to move up and contact with the pressure sensor 2 15. The pressure sensor 2 15 sends the received pressure signal to the alarm module, and the alarm module determines that the sampling box 2 has been reset. The water quality monitoring device is in the state of being in a state of being occupied by a wild animal. The water quality monitoring device is in the ...

[0024] Preferably, two sampling tubes 9 and two hoses 7 are provided, and are symmetrically arranged with the axis of the sampling box 2. The spoiler detection plate 10 is provided with two sections. The two sampling tubes are symmetrically arranged with the axis of the sampling box, and the two hoses are symmetrically arranged with the axis of the sampling box. Each section of the spoiler detection plate 10 is a vertically arranged plate structure. By setting two sampling tubes 9, the water bodies on both sides of the sampling box 2 can be sampled at the same time, and the water pressures on both sides can be verified with each other, thereby improving the accuracy of the sampling results.

[0025] The second implementation method: Figure 7 and Figure 8 It is shown that, different from the first embodiment, an air pump is installed in the monitoring box 1, and the output end of the air pump is connected to the hose 7. Solenoid valve 28 is installed at the hose 7 and the output end of the air pump, and the sampling module is electrically connected to the air pump and the solenoid valve 28 respectively. When sampling, the air pump is first controlled to work and the solenoid valve 28 is opened through the sampling module. The air pump injects gas into the inner cavity of the collection barrel 16 through the hose 7 and pushes the piston plate 23 downward. During the downward movement, part of the gas at the bottom of the piston plate 23 is discharged through the sampling tube 9. The amount of discharged gas is small and is not easy to affect the mixing of the water body. This operation can push out the residual water in the sampling tube 9 and reduce the impact on the collection of water samples.

[0026] In this embodiment, an air pressure sensor 26 is installed on the top of the inner cavity of the collection barrel 16, an elastic member 25 is installed on the bottom of the piston plate 23, and a blocking block 24 is fixed at the upper end of the side wall of the piston plate 23 corresponding to the opening of the sampling tube 9. The sampling module is electrically connected to the air pressure sensor 26. When the piston plate 23 moves downward, the blocking block 24 blocks the through hole 17 on the side, so that water is not easy to enter the top of the piston plate 23. The elastic member 25 can push the piston plate 23 to move up and reset, and the air pressure sensor 26 can detect the air pump through The air pressure data injected into the collection bucket 16 through the hose 7 is fed back to the sampling module, and the air pump is controlled by the sampling module. The hose 7 is located above the horizontal plane and is connected to a pressure relief pipe 29. The pressure relief pipe 29 is equipped with a solenoid valve three 30. The sampling module is electrically connected to the solenoid valve three 30. When the water in the collection bucket 16 needs to be quickly discharged, the solenoid valve three 30 and the solenoid valve one 11 are controlled to open through the sampling module. The water is quickly discharged through the through hole two 17 and the sampling tube 9 due to gravity, which is convenient for collection or the next sampling operation.

[0027] In view of current practical needs, the above-mentioned implementation mode adopted in this application is not limited to the scope of protection. Various changes made within the knowledge scope of technical personnel in this field without departing from the concept of this application still fall within the scope of protection of the present invention.
