Description

Technical Field

[0001] The present invention relates to a water quality monitoring device, and particularly to a water quality monitoring device for a wildlife-type nature reserve applied in the technical field of water quality monitoring. Background Art

[0002] A nature reserve refers to an area of land, inland water area or sea area where representative natural ecosystems, natural concentrated distributions of rare and endangered wild animal and plant species, and natural relics of special significance are located, and a certain area is legally demarcated for special protection and management. It is necessary to monitor the environment in the nature reserve in real time to prevent its ecological environment from being polluted. Among them, the water quality monitoring in the nature reserve is particularly important.

[0003] The invention patent with the publication number of CN116698515B discloses a water quality monitoring device, including a sampling part. The sampling part includes a U-shaped tube and a loop line. The loop line is arranged to wind through the lumen of the U-shaped tube. A plurality of sealing columns are connected in series on the loop line at equal intervals. The outer peripheral wall of the sealing column is in sealing cooperation with the inner wall of the lumen of the U-shaped tube. The top of the U-shaped tube is connected with a tensioning wheel, and the tensioning wheel tensions the loop line through a plurality of sealing columns. Above the U-shaped tube, a driving motor for driving the tensioning wheel to rotate is connected. A placement groove for inserting and matching with the self-closing sampling bottle is formed on the outer peripheral wall of the sealing column. By setting the U-shaped tube, valve tube, tensioning wheel, loop line, sealing column and self-closing sampling bottle, it is convenient to perform static sampling on fluctuating water bodies, and water bodies with different depths will not be mixed during sampling.

[0004] When the above technical method is implemented, it samples by immersing a plurality of self-closing sampling bottles into the water body one by one. When the sampling bottle enters the water body, it will stir the water body, easily mix water bodies with different depths, affecting the sampling accuracy. And when sampling with a traditional sampling bottle, when the sampling bottle enters the water body at a specified depth, during the process of water entering the sampling bottle, the gas in the sampling bottle will be discharged, and the discharged gas will stir the water body, resulting in the water body being mixed again during the sampling process, affecting the sampling result, and thus affecting the result of water body monitoring. Summary of the Invention

[0005] Aiming at the above-mentioned prior art, the technical problem to be solved by the present invention is that when sampling with a traditional sampling bottle, when the sampling bottle enters the water body at a specified depth, during the process of water entering the sampling bottle, the gas in the sampling bottle will be discharged, and the discharged gas will stir the water body, resulting in the water body being mixed again during the sampling process, affecting the sampling result, and thus affecting the result of water body monitoring.

A floating plate is sleeved on the driving rod, and a distance sensor is installed at the bottom of the floating plate;

[0009] The turbulence detection mechanism includes a detection shaft rotatably connected to the bottom of the sampling box and a turbulence detection plate installed on the detection shaft. A torque sensor is installed at the connection between the detection shaft and the sampling box;

[0010] The water quality monitoring intelligent controller is installed in the monitoring box. An instruction module, an intelligent total control module, a depth control module, a sampling module, and a turbulence detection module are provided on the water quality monitoring intelligent controller.

The depth control module is electrically connected to the distance sensor and the electric winch assembly respectively. The sampling module is electrically connected to the first solenoid valve, the pressure switch, and the driving member respectively. The turbulence detection module is electrically connected to the torque sensor.

[0011] In the above water quality monitoring device for wildlife type nature reserves, automatic sampling of water bodies at different depths is realized, and the disturbance situation of the water body at this depth is judged during sampling. It is possible to sample the water body when the water bodies at different water depths tend to be in a stable state, reduce the disturbance to the water body during the sampling process, and improve the accuracy of water body sampling.

[0012] As a further improvement of the present application, an elastic block is provided in the middle of each transposition clip. A top block is fixed at the position corresponding to the sampling pipe inside the cavity of the sampling box, and the top of the top block corresponds to the bottom of the elastic block. A first pressure sensor is installed at the bottom of the top block, and the sampling module is electrically connected to the first pressure sensor.

[0013] As a further improvement of the present application, two sampling pipes and two hoses are provided. The two sampling pipes are symmetrically arranged with respect to the axis of the sampling box, and the two hoses are symmetrically arranged with respect to the axis of the sampling box.

[0019] In summary, through the provided flow disturbance detection mechanism, the water body disturbance situation can be understood, and sampling can be carried out when the water body tends to be in a stable state. When sampling, the air in the collection bucket does not discharge from the second through hole, reducing the influence on the water body at this depth and reducing the mixing of water bodies at different depths, improving the sampling accuracy. And by driving the driving rod to rotate through the driving member, and driving multiple transposition clamps and the collection bucket to rotate synchronously, the multiple collection buckets are sequentially moved to the sampling pipe to perform sampling respectively, and the sampling box is put into different depths in cooperation, so as to sample the water bodies at different depths, judge the water body disturbance situation at this depth during sampling, sample the water body when the water bodies at different water depths tend to be in a stable state, and it is not easy to disturb the water body at this depth during the sampling process, improving the accuracy of water body sampling.

[0030] The following describes the two embodiments of the present application in detail with reference to the accompanying drawings.

[0031] The first embodiment:

[0032] Figures 1 - 7Disclosed is a water quality monitoring device for a wildlife type nature reserve, which comprises a monitoring box 1, a sampling box 2, a flow disturbance detection mechanism and a water quality monitoring intelligent controller; the monitoring box 1 is connected to the installation surface through a mounting frame 3. By installing the monitoring box 1 above the water surface, it is convenient to monitor the water quality of the water body at any time. A driving member 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 pipe 9 is connected to the side of the sampling box 2, a solenoid valve 11 is installed on the sampling pipe 9, a hose 7 is connected to the top of the sampling box 2, the top of the hose 7 is placed inside the cavity of the monitoring box 1, and a plurality of collection barrels 16 are circumferentially distributed in the cavity of the sampling box 2. A through hole 18 corresponding to the bottom end of the hose 7 is opened at the top of each collection barrel 16, and a through hole 17 corresponding to the sampling pipe 9 is opened at the side of each collection barrel 16. A rope 8 connected to the output end of the electric winch assembly is fixed to the top of the sampling box 2. A driving rod 4 connected to the output end of the driving member is vertically inserted into the middle of the sampling box 2. A plurality of switching clips 19 engaged with the collection barrels 16 are fixed to the bottom end of the driving rod 4. A piston plate 23 is vertically slidably connected to the inner cavity of the collection barrel 16. A pressure switch 27 is installed at the top of the inner cavity of the collection barrel 16. A floating plate 5 is sleeved on the driving rod 4. A distance sensor 6 is installed at the bottom of the floating plate 5. By controlling the elongation and shortening of the rope 8 through the electric winch assembly, the sampling box 2 is put into a specified depth of the water body. Since the water level is different in different seasons, by setting the floating plate 5, 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 body enters the inner cavity of the collection barrel 16 from the through hole 17 through the sampling pipe 9. The water pressure pushes the piston plate 23 to move upward, pushing the air at the top of the collection barrel 16 upward and discharging it into the inner cavity of the monitoring box 1 and the external environment through the hose 7. When sampling, the air in the collection barrel 16 does not discharge from the through hole 17, reducing the influence on the water body at this depth and reducing the mixing of water bodies at different depths, improving the sampling accuracy. And by driving the driving rod 4 to rotate through the driving member, driving a plurality of switching clips 19 and the collection barrels 16 to rotate synchronously, moving the plurality of collection barrels 16 to the sampling pipe 9 in turn for sampling respectively, and cooperating with putting the sampling box 2 into different depths, so as to sample the water bodies at different depths.

[0033] In addition, please refer to Figure 2 and Figure 6 , the flow disturbance detection mechanism includes a detection shaft 14 rotatably connected to the bottom of the sampling box 2 and a flow 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 flow disturbance detection plate 10 and drive the detection shaft 14 to rotate forward and backward. The rotation state of the detection shaft 14 can be detected through the torque sensor 31, so as to understand the water body disturbance situation.

[0034] 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 an instruction module, an intelligent master control module, a depth control module, a sampling module and a turbulence detection module. The intelligent master control module is electrically connected to the instruction module, the depth control module, the sampling module and the turbulence 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 turbulence detection module is electrically connected to the torque sensor 31. By inputting the sampling time and the water body sampling depth to the instruction module, when sampling, the instruction module sends a sampling signal to the intelligent master control module. The intelligent master control module controls the depth control module to lower the sampling box 2 to the 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 reaching the preset depth, it controls the electric winch assembly to stop working and feeds back the result to the intelligent master control module. During this process, the water flow impacts the turbulence detection plate 10 and pushes the detection shaft 14 to rotate forward and backward repeatedly. The torque sensor 31 receives the torsion data of the detection shaft 14 and sends it to the turbulence detection module. When the turbulence detection module detects that the torsion data fluctuates greatly repeatedly (greater than the reasonable fluctuation range preset by the turbulence detection module), it judges that the water body is unstable and in a mixed state, and feeds back a signal that sampling cannot be performed to the intelligent master control module. When the turbulence detection module detects that the torsion data fluctuates slightly repeatedly (within the reasonable fluctuation range preset by the turbulence detection module), it judges that the water body is in a stable state, and the water bodies at different depths tend to be stable, and feeds back a signal that sampling can be performed to the intelligent master control module. At this time, the intelligent master control module sends a sampling signal to the sampling module. The sampling module controls the driving member to work. The driving member controls the collection bucket 16 to move to the sampling pipe 9 in turn through the driving rod 4 and the transposition clamp 19, and controls the solenoid valve 11 to open. The water body enters the bottom of the collection bucket 16 through the sampling pipe 9 and the through hole 17. The gas in the collection bucket 16 is discharged into the air through the through hole 18 and the hose 7 to reduce the situation of water body mixing. 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 the sampled water body. The sampling module judges that the collection bucket 16 is full by receiving the feedback signal of the push switch 27 and feeds back a full load signal to the intelligent master control module. The intelligent master control module repeats the sampling of the water body at the next depth through the depth control module. After 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, realizing automatic sampling of water bodies at different depths, and judging the disturbance situation of the water body at this depth during sampling. Sampling is performed on the water body when the water bodies at different depths tend to be stable. During the sampling process, it is not easy to disturb the water body at this depth, improving the accuracy of water body sampling.

[0035] In addition, please refer to Figure 4 , Figure 5 and Figure 7 . An elastic block 20 is provided in the middle of each transposition clip 19. A top block 21 is fixed at the corresponding position of 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 of the elastic block 20. A first pressure sensor 22 is installed at the bottom of the top block 21. The sampling module is electrically connected to the first pressure sensor 22. When the transposition clip 19 drives the corresponding collection bucket 16 to move to the sampling tube 9, at this time, the elastic block 20 on the transposition clip 19 contacts the top of the top block 21. The top of the top block 21 plays a role in expanding and supporting the elastic block 20 made of elastic material, so that the transposition clip 19 elongates and pushes the collection bucket 16 closer to the sampling tube 9. Therefore, the second through hole 17 will closely adhere to the end of the sampling tube 9 to improve the tightness. And when the top block 21 is squeezed by the elastic block 20, the first pressure sensor 22 feeds back the received pressure signal to the sampling module. The sampling module can accurately judge that the collection bucket 16 has moved to the corresponding position of the sampling tube 9, which is convenient for sampling operation.

[0036] In this embodiment, please refer to Figure 1 and Figure 2 . A second pressure sensor 15 is installed at the corresponding position of the bottom of the monitoring box 1 and the floating disk 5. An acoustic-optic alarm component 12 and an infrared sensor 13 are installed on the top of the monitoring box 1. An alert module electrically connected to the intelligent total control module is also provided on the water quality monitoring intelligent controller. The alert module is electrically connected to the acoustic-optic alarm component 12, the infrared sensor 13, and the second pressure sensor 15 respectively. By setting the alert module, when the depth control module controls the sampling box 2 to reset after sampling, at this time, the sampling box 2 moves upward and pushes the floating disk 5 upward to contact the second pressure sensor 15. The second pressure sensor 15 sends the received pressure signal to the alert module. The alert module judges that the sampling box 2 has been reset and sends a reset signal to the intelligent total control module. The intelligent total control module sends a stop reset signal to the depth control module. And the infrared sensor 13 provided can detect whether there are wild animals approaching near the water quality monitoring device, and send a reminder signal to the alert module after detecting wild animals. The alert module issues corresponding acoustic-optic reminders through the acoustic-optic alarm component 12 to drive away the wild animals, so as to provide a safe environment when the operator operates at the monitoring device. The infrared sensor 13 can also detect the operator and send a corresponding reminder sound to keep the operator vigilant and ensure the safety of the operator in the nature reserve of wild animal types.

[0037] Preferably, there are two sampling tubes 9 and two hoses 7, and they are symmetrically arranged with respect to the axis of the sampling box 2. There are two sections of the flow disturbance detection plate 10. The two sampling tubes are symmetrically arranged with respect to the axis of the sampling box, and the two hoses are symmetrically arranged with respect to the axis of the sampling box. Each section of the flow disturbance detection plate 10 is a vertically arranged plate-like structure. By providing two sampling tubes 9, the water bodies on both sides of the sampling box 2 can be sampled simultaneously, and the water pressures on both sides can verify each other, improving the accuracy of the sampling results.

[0038] The second implementation mode:

[0039] Figure 7 and Figure 8 As shown, different from the first implementation mode, an air pump is installed in the monitoring box 1. The output end of the air pump is communicated with the hose 7. An electromagnetic valve II 28 is installed at the output end of the hose 7 and the air pump. The sampling module is electrically connected to the air pump and the electromagnetic valve II 28 respectively. When sampling, first, the sampling module controls the air pump to work and the electromagnetic valve II 28 to open. The air pump injects gas into the inner cavity of the collection bucket 16 through the hose 7 and pushes the piston plate 23 to move downward. During the downward movement, a part of the gas at the bottom of the piston plate 23 is discharged through the sampling tube 9. The discharged gas volume is small and is not likely to affect the water body mixing situation. This operation can push out the residual water body at the sampling tube 9, reducing the influence on the collected water sample.

[0040] In this implementation mode, a pressure sensor 26 is installed at the top of the inner cavity of the collection bucket 16. An elastic member 25 is installed at the bottom of the piston plate 23. A blocking block 24 is fixed at the position corresponding to the opening of the sampling tube 9 on the upper end of the side wall of the piston plate 23. The sampling module is electrically connected to the pressure sensor 26. During the downward movement of the piston plate 23, the through hole II 17 on the side is blocked by the blocking block 24, so that the water body is not easily introduced into the top of the piston plate 23. The elastic member 25 can push the piston plate 23 to move upward and reset. The pressure sensor 26 can detect the air pressure data injected into the collection bucket 16 by the air pump through the hose 7 and feedback it to the sampling module. The sampling module controls the operation of the air pump. A pressure relief pipe 29 is connected to the hose 7 above the horizontal plane. An electromagnetic valve III 30 is installed on the pressure relief pipe 29. The sampling module is electrically connected to the electromagnetic valve III 30. When it is necessary to quickly discharge the water in the collection bucket 16, the sampling module controls the electromagnetic valve III 30 and the electromagnetic valve I 11 to open. Under the action of gravity, the water body quickly discharges through the through hole II 17 and the sampling tube 9, which is convenient for collection or the next sampling operation.

[0041] Combined with the current actual requirements, the above implementation modes adopted by this application, the protection scope is not limited to this. Within the knowledge scope of those skilled in the art, various changes made without departing from the concept of this application still fall within the protection scope of the present invention.
