Description

Technical Field

[0001] The present invention relates to the technical field of water environment monitoring, and in particular to a water environment monitoring device and a monitoring method thereof. Background Art

[0002] Water environment monitoring refers to the unified regular or real-time monitoring of water quality and various artificial and natural factors in water bodies that affect ecological and environmental quality. Water environment monitoring equipment is usually required for operation. Since there are many factors affecting the water environment, the monitoring scope of water body data is relatively wide. A single water environment monitoring cannot meet different data monitoring needs. Therefore, in actual operation, staff are usually required to take water samples in specific water environment areas at regular intervals and transfer them to the laboratory for testing of various data. In order to improve the convenience of water sampling, it is necessary to use sampling equipment that can take samples multiple times.

[0003] After searching, a patent document with publication number CN220690579U discloses a multi-layer depth sampling device for water environment monitoring, including a sampling device bracket, a surface of the sampling device bracket is fixedly connected to a sliding rod, a surface of the sliding rod is slidably connected to a sliding block, a lower surface of the sliding block is slidably connected to a hydraulic telescopic rod, and a multi-depth sampling device is arranged on the lower surface of the hydraulic telescopic rod.

[0004] Although the above-mentioned multi-layer depth sampling device for water environment monitoring can sample water bodies at different depths, it still has the following shortcomings:

[0005] The water body cannot be tested directly during the sampling process, which results in a large amount of data that needs to be tested in the laboratory, reducing the overall detection efficiency, and it is impossible to perform multiple sampling processes according to the time span requirements of water environment monitoring. In actual operations, staff still need to perform multiple sampling at regular intervals and locations to meet the time span monitoring requirements of the water environment, resulting in the overall monitoring operation still not being convenient enough. Therefore, it is necessary to design a water environment monitoring device and a monitoring method thereof. Summary of the invention

[0006] In view of the deficiencies in the prior art, the present invention provides a water environment monitoring device and a monitoring method thereof, which solve the problems raised in the above-mentioned background technology.

[0007] In order to achieve the above object, the present invention adopts the following technical solutions:

[0008] A water environment monitoring device, comprising a waterproof housing, and further comprising:

[0009] A partition fixedly installed in the waterproof housing, the partition dividing the interior of the waterproof housing into two detection chambers of the same size, wherein a pH detection probe and a conductivity probe are fixedly installed in the two detection chambers respectively;

[0010] The water intake part is used to extract and detect water samples in the environment. The water intake part includes a sealing ring rotatably mounted on the waterproof housing and piston plates respectively installed in two detection chambers in a sealing and sliding manner. The two piston plates are respectively connected to the pH detection probe and the conductivity probe in a sliding and sealing manner. A synchronization component is installed between the sealing ring and the two piston plates.

[0011] The sample retaining part is used to partially preserve the water sample extracted by the water intake part. The sample retaining part includes a cavity opened at the bottom of the partition, and a sealing rotating sleeve is rotatably installed in the cavity. The sealing rotating sleeve is fixedly connected to a sampling tube, and a transmission component is installed between the sealing ring and the sealing rotating sleeve.

[0012] Furthermore, water inlets are provided on the left and right side walls of the waterproof shell, and the two water inlets are respectively communicated with the corresponding detection chambers. An annular groove that rotates with a sealing ring is provided on the upper side wall of the waterproof shell, and the annular groove is communicated with the two water inlets. The sealing ring is provided with alignment holes that cooperate with the two water inlets.

[0013] Furthermore, the partition and the bottom of the waterproof housing are both provided with a through hole, and a sealing base is threadedly connected to the through hole, and a plurality of storage bottles matching the sampling tubes are installed on the sealing base.

[0014] Furthermore, the synchronization assembly consists of a belt transmission structure, an incomplete gear ring, a transmission gear and two screw rods. The two screw rods are rotatably mounted on the waterproof housing, and the two screw rods are respectively threadedly connected to the two piston plates. The belt transmission structure is installed between the tops of the two screw rods, and the transmission gear is fixedly installed on one of the screw rods. The incomplete gear ring is fixedly installed on the inner wall of the sealing ring outside the annular groove, and the incomplete gear ring cooperates with the transmission gear. A torsion spring is installed between the transmission gear and the waterproof housing.

[0015] Furthermore, a power supply block is fixedly mounted on the waterproof housing, and power lines are connected between the power supply block and the pH detection probe and the conductivity probe.

[0016] Furthermore, a sealing cover is fixedly installed on the top of the waterproof housing, and an electric motor is fixedly installed on the top of the sealing cover, a driving rod is fixedly connected to the output end of the electric motor, and two L-shaped rods are fixedly installed between the side wall of the driving rod and the top of the sealing ring, and a connection plate that matches the power supply block is fixedly installed at the bottom of the two L-shaped rods, a controller is fixedly installed on the top of the sealing cover, and the controller is electrically connected to the electric motor, the pH detection probe and the conductivity probe.

[0017] Furthermore, the side wall of the partition is provided with sampling holes having the same number as the storage bottles, and the plurality of sampling holes are interconnected with the cavity.

[0018] Furthermore, the transmission assembly consists of a rotating rod, a fixed gear, a connecting gear and two incomplete gear rings. The rotating rod is rotatably installed between the partition and the waterproof shell, and the rotating rod is fixedly connected to the top of the sealing rotating sleeve. The fixed gear is fixedly installed on the top of the rotating rod. The connecting gear is rotatably installed on the top of the waterproof shell through a rotating shaft, and the connecting gear is meshed with the fixed gear. The two incomplete gear rings are fixedly installed on the inner wall of the sealing ring, and the two incomplete gear rings cooperate with the connecting gear.

[0019] Furthermore, a floating ring is fixedly installed on the side wall of the waterproof housing, and two one-way drainage pipes are fixedly connected to the waterproof housing, and the two one-way drainage pipes are respectively communicated with the bottom of the corresponding detection cavity.

[0020] A monitoring method of a water environment monitoring device, using the above-mentioned water environment monitoring device, comprises the following steps:

[0021] S1: Check whether the controller, electric motor, pH detection probe, conductivity probe, power supply block and switch board can be used normally. After checking that there are no problems, place the device in the specified water environment and use anchors or other methods to limit the position of the device in the water environment;

[0022] S2: Control the operation of the electric motor according to the monitoring sampling time set by the system. When the electric motor is working, the sealing ring is driven to rotate through the cooperation of the driving rod and the L-shaped rod. When the alignment hole on the sealing ring corresponds to one of the water inlets, the moisture in the environment automatically enters the corresponding detection cavity from the water inlet due to the water pressure;

[0023] S3: When the alignment hole and the water inlet are in correspondence, the corresponding connection plate and the power supply block are also in contact with each other, and the corresponding pH detection probe or conductivity probe starts to work, automatically detecting the pH value or conductivity of the ambient water, and transmitting the detection results to the background through the controller for recording;

[0024] S4: When the sealing ring continues to rotate so that the alignment hole and the water inlet are staggered, the water inlet is in a closed state, and then the incomplete gear ring 1 contacts and meshes with the transmission gear. As the sealing ring continues to rotate, the piston plate moves downward in the detection chamber. At this time, the ambient water drawn into the detection chamber is discharged through the one-way drain pipe, and the pH detection probe or conductivity probe is cleaned by the downward movement of the piston plate;

[0025] S5: After the incomplete gear ring 1 contacts and meshes with the transmission gear, the incomplete gear ring 2 will also contact and mesh with the connecting gear, driving the sealing rotating sleeve to rotate a certain angle, so that the sampling tube on it can be aligned with the corresponding sampling hole and then separated. During this process, due to the continuous downward movement of the piston plate, some environmental water will be sent into the storage bottle through the sampling tube, and then the incomplete gear ring 2 will be separated from the connecting gear first, and then the incomplete gear ring 1 will be separated from the transmission gear. The elastic force of the torsion spring causes the piston plate to move up and reset;

[0026] S6: Repeat the monitoring and sampling processes of S2-S5 above. When multiple storage bottles are filled with water samples or the monitoring time reaches the specified range, take the equipment out of the water environment, then unscrew the sealed base to take out the water samples in the multiple storage bottles, mark them and send them to the laboratory for other tests. Combined with the pH value test results and conductivity test results during use, multiple monitoring results of the water body in the water environment can be obtained, which improves the accuracy of the overall monitoring results and is also convenient for judging the water quality of the water environment at different times based on the water body monitoring results at different time periods.

[0027] Compared with the prior art, the present invention has the following advantages:

[0028] 1: The water environment monitoring equipment has the advantages of automatically sampling water, detecting pH value and conductivity. Specifically, through the cooperation of water inlet, pH detection probe, conductivity probe, sampling tube and storage bottle, the pH value and conductivity detection of water can be completed during the sampling process, thereby reducing the detection items in the laboratory and improving the overall detection efficiency.

[0029] 2: The water environment monitoring equipment has the advantage of being able to perform multiple sampling, pH value and conductivity testing within a certain period of time. Specifically, through the cooperation of multiple sampling holes and multiple storage bottles, the equipment can be used to perform multiple sampling of the water body at a time, which effectively improves convenience.

[0030] 3: The water environment monitoring equipment has the advantages of simple structure and high degree of automation. Specifically, through the cooperation of the sealing ring, the sealing rotating sleeve, the synchronous assembly and the transmission assembly, the driving motor can be used to complete the pumping, detection, drainage and sample retention operations in an orderly manner without manual control.

[0031] In summary, the present invention can automatically perform multiple sampling, pH value and conductivity detection on the water environment within a certain time span, which effectively meets the time span requirements of water environment monitoring, and can also reduce subsequent water body detection items and improve overall detection efficiency.

DETAILED DESCRIPTION

[0045] Reference Figure 1-Figure 12 A water environment monitoring device includes a waterproof shell 1. As the name implies, the waterproof shell 1 is made of waterproof material and can be in a water environment for a long time without being damaged. When the device is used, it is placed in a water environment. A floating ring 21 is fixedly installed on the side wall of the waterproof shell 1. Under the action of the floating ring 21, the device can be prevented from sinking directly to the bottom of the water and causing damage. It also includes a partition 2 fixedly installed in the waterproof shell 1. The partition 2 divides the interior of the waterproof shell 1 into two detection chambers of the same size. Both detection chambers can be used to extract and detect water in the water environment. A pH detection probe 12 and a conductivity probe 13 are fixedly installed in the two detection chambers, respectively. The pH detection probe 12 can specifically adopt an existing pH meter probe. Its working principle and specific structure are not described here. When power is turned on, the pH value of the water body can be directly detected. The conductivity probe 13 is also an existing product. Its working principle and specific structure are not described here. When power is turned on, the conductivity of the water body can be directly detected, thereby reflecting whether the water body is polluted. For example, industrial wastewater discharge or agricultural runoff may increase the ion concentration in the water, thereby improving the conductivity.

[0046] A power supply block 14 is fixedly installed on the waterproof housing 1, and a power line 15 is connected between the power supply block 14 and the pH detection probe 12 and the conductivity probe 13. The power supply block 14 can be integrated with a touch switch and a battery. When the touch switch on it is touched, the battery supplies power to the pH detection probe 12 and the conductivity probe 13 through the power line 15. At this time, the pH detection probe 12 and the conductivity probe 13 can detect the pH value and conductivity of the water body.

[0047] Water inlets 3 are provided on the left and right side walls of the waterproof housing 1, and the two water inlets 3 are respectively communicated with the corresponding detection chambers. At the same time, the water inlets 3 are located at the lower end of the floating ring 21. When the water inlets 3 remain unobstructed, the water in the water environment can enter the detection chamber under the action of water pressure. At this time, the pH detection probe 12 and the conductivity probe 13 are powered, and the pH value and conductivity of the water can be directly detected, which is convenient for real-time reflection of the pH value and conductivity of the water. There is no need to perform the same test on the water after sampling, which can effectively improve the overall monitoring efficiency.

[0048] The water intake part is used to extract and detect water samples in the environment. The water intake part includes a sealing ring 8 rotatably mounted on the waterproof housing 1 and piston plates 4 respectively installed in two detection chambers in a sealing and sliding manner. The two piston plates 4 are respectively connected to the pH detection probe 12 and the conductivity probe 13 in a sliding and sealing manner. A circular hole is provided on the piston plate 4. The upper and lower ends of the circular hole are fixed with rubber sealing rings with cross cuts. When the piston plate 4 moves relative to the pH detection probe 12 and the conductivity probe 13, the rubber sealing ring can be used to clean the pH detection probe 12 and the conductivity probe 13. When the piston plate 4 is separated from the pH detection probe 12 and the conductivity probe 13, the cross cut on the rubber sealing ring remains sealed, and at this time, the piston plate 4 will not have a water leakage problem;

[0049] The upper side wall of the waterproof shell 1 is provided with an annular groove 7 which cooperates with the sealing ring 8 for rotation, and the annular groove 7 is interconnected with the two water inlets 3. The sealing ring 8 is provided with an alignment hole 9 which cooperates with the two water inlets 3. When the sealing ring 8 rotates, the alignment hole 9 thereon will move relative to the water inlet 3. When the alignment hole 9 is relative to the water inlet 3, the water body can enter the corresponding detection cavity through the water inlet 3. Conversely, when the water inlet 3 and the alignment hole 9 are interlaced, the external water body cannot enter the detection cavity. Setting the size of the alignment hole 9 to be smaller than the size of the water inlet 3 can increase the alignment time of the two. Therefore, sufficient water can enter the detection cavity during the continuous rotation of the sealing ring 8, ensuring that the pH detection probe 12 and the conductivity probe 13 can effectively complete the pH value and conductivity detection of the water body.

[0050] A synchronization component is installed between the sealing ring 8 and the two piston plates 4. The synchronization component consists of a belt transmission structure 6, an incomplete gear ring 10, a transmission gear 11 and two screw rods 5. The two screw rods 5 are rotatably installed on the waterproof housing 1, and the two screw rods 5 are respectively threadedly connected to the two piston plates 4. When the screw rods 5 rotate, the piston plates 4 can move up and down in the detection chamber through the threaded connection effect between the screw rods 5 and the piston plates 4. There are two one-way drainage pipes 22 fixedly connected to the waterproof housing 1, and the two one-way drainage pipes 22 are respectively connected to the corresponding detection The bottoms of the cavities are interconnected. When the piston plate 4 moves downward at the upper end of the detection cavity, the moisture in the detection cavity can be discharged from the one-way drain pipe 22. The upper port of the one-way drain pipe 22 is located above the water inlet 3. The purpose of the design at this time is to reduce the resistance encountered by water entering the detection cavity through the water inlet 3. A one-way constant pressure port is provided on the piston plate 4. The one-way constant pressure port can make the air above the piston plate 4 flow downward under sufficient pressure. Therefore, the air pressure at the lower end can be kept constant when the water inlet 3 is closed and the piston plate 4 completes the drainage and upward movement.

[0051] The belt transmission structure 6 is installed between the tops of the two screw rods 5. The belt transmission structure 6 is a prior art, and its working principle and specific structure are not described here. Through the design of the belt transmission structure 6, when one of the screw rods 5 rotates, the other screw rod 5 can rotate in the same direction at the same time. The transmission gear 11 is fixedly installed on one of the screw rods 5, and the incomplete gear ring 10 is fixedly installed on the inner wall of the sealing ring 8 outside the annular groove 7, and the incomplete gear ring 10 cooperates with the transmission gear 11. When the sealing ring 8 rotates to make the alignment hole 9 on it move from the aligned position with the water inlet 3 to the separated position, the incomplete gear ring 10 and the transmission gear 11 are connected to each other. The screw rod 5 rotates simultaneously under the action of the rotation of the sealing ring 8, so that the piston plate 4 moves downward from the top of the detection chamber, completing the discharge of water and the cleaning of the pH detection probe 12 and the conductivity probe 13. A torsion spring is installed between the transmission gear 11 and the waterproof housing 1. When the sealing ring 8 continues to rotate and the alignment hole 9 thereon has not yet been aligned with the position of the other water inlet 3, the piston plate 4 moves to the bottom of the detection chamber. At this time, the incomplete gear ring 10 and the transmission gear 11 are separated from each other, and the elastic force of the torsion spring can make the screw rod 5 rotate in the reset direction, so that the piston plate 4 is reset and moved to the top of the detection chamber to prepare for the next movement.

[0052] A sealing cover 16 is fixedly installed on the top of the waterproof housing 1, and an electric motor 17 is fixedly installed on the top of the sealing cover 16. A driving rod 18 is fixedly connected to the output end of the electric motor 17, and two L-shaped rods 19 are fixedly installed between the side wall of the driving rod 18 and the top of the sealing ring 8. When the electric motor 17 is working, the driving rod 18 and the L-shaped rod 19 provide driving force for the rotation of the sealing ring 8. A connection plate 20 that matches the power supply block 14 is fixedly installed at the bottom of the two L-shaped rods 19. When the connection plate 20 contacts the power supply block 14, the touch switch on the power supply block 14 is touched, and the power supply block 14 can perform power supply processing at this time. A controller 23 is fixedly installed on the top of the sealing cover 16, and the controller 23 is electrically connected to the electric motor 17, the pH detection probe 12 and the conductivity probe 13. The design of the controller 23 is convenient for controlling the start-up interval time of the electric motor 17 according to the system setting, and can timely transmit the detection results of the pH detection probe 12 and the conductivity probe 13 to the background system.

[0053] The sample retaining part is used to partially preserve the water sample extracted by the water intake part. The sample retaining part includes a cavity 24 opened at the bottom of the partition 2. The partition 2 and the bottom of the waterproof shell 1 are jointly provided with a through hole. The through hole is interconnected with the bottom of the cavity 24, and a sealing base 25 is threadedly connected to the through hole. The sealing base 25 can seal the bottom of the cavity 24 when the device is used. A plurality of storage bottles 29 are installed on the sealing base 25. The storage bottles 29 are used to partially retain the water entering the detection cavity and preserve it as a water sample to facilitate subsequent other detection and processing of the water sample.

[0054] A sealing rotating sleeve 26 is rotatably installed in the cavity 24, and a sampling tube 28 is fixedly connected to the sealing rotating sleeve 26, and the sampling tube 28 cooperates with multiple storage bottles 29. The side wall of the partition 2 is provided with sampling holes 27 with the same number as the storage bottles 29, and the multiple sampling holes 27 are interconnected with the cavity 24. When the lower end of the sampling tube 28 on the sealing rotating sleeve 26 is aligned with one of the sampling holes 27, part of the water in the detection chamber can be sent to the storage bottle 29 for preservation through the sampling tube 28 during the downward movement of the piston plate 4. On the contrary, when the sampling tube 28 on the sealing rotating sleeve 26 is not aligned with any sampling hole 27, the downward movement of the piston plate 4 will only discharge the water in the detection chamber from the one-way drain pipe 22.

[0055] A transmission assembly is installed between the sealing ring 8 and the sealing rotating sleeve 26, and the transmission assembly consists of a rotating rod 30, a fixed gear 31, a connecting gear 32 and an incomplete gear ring 23. The rotating rod 30 is rotatably installed between the partition 2 and the waterproof shell 1, and the rotating rod 30 is fixedly connected to the top of the sealing rotating sleeve 26. The rotation of the rotating rod 30 can drive the sealing rotating sleeve 26 to rotate in the cavity 24. At this time, the position correspondence between the sampling tube 28 and the multiple sampling holes 27 and the multiple storage bottles 29 can be controlled. The fixed gear 31 is fixedly installed on the top of the rotating rod 30, and the connecting gear 32 is rotatably installed on the top of the waterproof shell 1 through the rotating shaft. The rotating shaft is rotatably connected to the waterproof shell 1. The connecting gear 32 is fixedly installed on the top of the rotating shaft, and the connecting gear 32 is meshed with the fixed gear 31. Through the meshing relationship between the two, the fixed gear 31 can be driven to rotate simultaneously when the connecting gear 32 rotates. The incomplete gear ring 23 is fixedly installed on the inner wall of the sealing ring 8, and the incomplete gear ring 23 and the connecting gear 32 In coordination, when the incomplete gear ring 10 and the transmission gear 11 are meshed with each other and move relative to each other for a certain distance (i.e., during the downward movement of the piston plate 4 to drain water), the incomplete gear ring 2 33 is meshed with the connecting gear 32. By controlling the ratio of the number of teeth on the incomplete gear ring 2 33 to the number of teeth on the connecting gear 32, the incomplete gear ring 2 33 drives the connecting gear 32 to rotate a smaller amplitude, thereby causing the rotating rod 30 to rotate a certain angle (specifically, it can be controlled according to the number of storage bottles 29, so that the angle of each rotation of the rotating rod 30 is 360° divided by the number of storage bottles 29). During the rotation of the rotating rod 30, the sampling tube 28 will perform an "approach-align-separation" movement relative to one of the sampling holes 27. Then, a certain amount of water can be input into the storage bottle 29 at the corresponding position during this process. In order to facilitate the subsequent distinction of the sampling time of the water sample in each storage bottle 29, each storage bottle 29 can be digitally marked in sequence along the rotation direction of the sampling tube 28.

[0056] The second embodiment of the present invention:

[0057] There are two alignment holes 9 on the sealing ring 8, and there are two incomplete gear rings 10 and 33. The two alignment holes 9, the two incomplete gear rings 10 and the two incomplete gear rings 2 33 are symmetrically arranged. There is one connection plate 20, and it can control the switches of the pH detection probe 12 and the conductivity probe 13 at the same time. The advantage of this embodiment is that the sealing ring 8 only needs to rotate 180° each time to complete the simultaneous detection of the pH value and conductivity of the water body and the single sample retention operation.

[0058] In the present invention, a monitoring method of a water environment monitoring device comprises the following steps:

[0059] Equipment placement: Check whether the controller 23, the electric motor 17, the pH detection probe 12, the conductivity probe 13, the power supply block 14 and the connection board 20 can be used normally. After the inspection is completed, the device is placed in the specified water environment and the position of the device in the water environment is defined by anchors or other means;

[0060] Water collection detection: The operation of the electric motor 17 is controlled according to the monitoring sampling time set by the system. When the electric motor 17 is working, the sealing ring 8 is driven to rotate through the cooperation of the driving rod 18 and the L-shaped rod 19. When the alignment hole 9 on the sealing ring 8 corresponds to one of the water inlets 3, the water in the environment automatically enters the corresponding detection cavity from the water inlet 3 due to the water pressure;

[0061] When the alignment hole 9 corresponds to the water inlet 3, the corresponding connection plate 20 and the power supply block 14 also contact each other, and the corresponding pH detection probe 12 or conductivity probe 13 starts to work, automatically detecting the pH value or conductivity of the ambient water, and transmits the detection result to the background through the controller 23 for recording;

[0062] Water discharge: When the sealing ring 8 continues to rotate so that the alignment hole 9 is staggered with the water inlet 3, the water inlet 3 is in a closed state, and then the incomplete gear ring 10 contacts and meshes with the transmission gear 11. As the sealing ring 8 continues to rotate, the piston plate 4 moves downward in the detection chamber. At this time, the environmental water drawn into the detection chamber is discharged through the one-way drain pipe 22, and the pH detection probe 12 or the conductivity probe 13 is cleaned by the downward movement of the piston plate 4;

[0063] Water sampling: After the incomplete gear ring 10 contacts and meshes with the transmission gear 11, the incomplete gear ring 2 33 will also contact and mesh with the connecting gear 32, driving the sealing rotating sleeve 26 to rotate a certain angle, so that the sampling tube 28 on it can be aligned with the corresponding sampling hole 27 and then separated. During this process, due to the continuous downward movement of the piston plate 4, part of the environmental water will be sent to the storage bottle 29 through the sampling tube 28, and then the incomplete gear ring 2 33 will be separated from the connecting gear 32 first, and then the incomplete gear ring 10 will be separated from the transmission gear 11, and the elastic force of the torsion spring will cause the piston plate 4 to move up and reset;

[0064] Cross-time period monitoring: The controller 23 starts the electric motor 17 multiple times at intervals within a certain period of time according to the time interval set by the system, and repeats the above-mentioned water extraction detection and water sample retention processing. When multiple storage bottles 29 are filled with water samples or the monitoring time reaches the specified range, the device is taken out from the water environment, and then the sealing base 25 is unscrewed to take out the water samples in the multiple storage bottles 29, mark them and send them to the laboratory for other tests. Combined with the pH value test results and conductivity test results during use, multiple monitoring results of the water environment at that time can be obtained, thereby improving the accuracy of the overall monitoring results, and it is also convenient to judge the water quality of the water environment at different times based on the water body test results of different time periods.

[0065] The above shows and describes the basic principles and main features of the present invention and the advantages of the present invention. It should be understood by those skilled in the art that the present invention is not limited by the above embodiments, and the above embodiments and descriptions are only for explaining the principles of the present invention. Without departing from the spirit and scope of the present invention, the present invention may have various changes and improvements, and these changes and improvements all fall within the scope of the present invention to be protected.

3. A monitoring method of a water environment monitoring device, using the water environment monitoring device as claimed in claim 2, characterized in that: The following steps are involved: S1: Check whether the controller (23), the electric motor (17), the pH detection probe (12), the conductivity probe (13), the power supply block (14) and the connection board (20) can be used normally. After checking that there are no problems, place the device in a specified water environment and use an anchor or other means to limit the position of the device in the water environment; S2: Controlling the operation of the electric motor (17) according to the monitoring sampling time set by the system, when the electric motor (17) is working, the driving rod (18) and the L-shaped rod (19) cooperate to drive the sealing ring (8) to rotate, and when the alignment hole (9) on the sealing ring (8) corresponds to one of the water inlets (3), the moisture in the environment automatically enters the corresponding detection cavity from the water inlet (3) due to the water pressure; S3: When the alignment hole (9) corresponds to the water inlet (3), the corresponding connection plate (20) and the power supply block (14) are also in contact with each other, and the corresponding pH detection probe (12) or conductivity probe (13) starts to work, automatically performs pH value detection or conductivity detection on the ambient water, and transmits the detection result to the background through the controller (23) for recording; S4: When the sealing ring (8) continues to rotate so that the alignment hole (9) and the water inlet (3) are interlaced, the water inlet (3) is in a closed state, and then the incomplete gear ring (10) contacts and meshes with the transmission gear (11). As the sealing ring (8) continues to rotate, the piston plate (4) moves downward in the detection chamber. At this time, the ambient water drawn into the detection chamber is discharged through the one-way drain pipe (22), and the pH detection probe (12) or the conductivity probe (13) is cleaned by the downward movement of the piston plate (4); S5: After the incomplete gear ring 1 (10) contacts and meshes with the transmission gear (11), the incomplete gear ring 2 (33) also contacts and meshes with the connecting gear (32), driving the sealing rotating sleeve (26) to rotate a certain angle, so that the sampling tube (28) on it can be aligned with the corresponding sampling hole (27) and then separated. During this process, due to the continuous downward movement of the piston plate (4), part of the ambient water will be sent into the storage bottle (29) through the sampling tube (28), and then the incomplete gear ring 2 (33) will be separated from the connecting gear (32), and then the incomplete gear ring 1 (10) will be separated from the transmission gear (11), and the elastic force of the torsion spring will cause the piston plate (4) to move up and reset; S6: Repeat the monitoring and sampling process of S2-S5. When the multiple storage bottles (29) are filled with water samples or the monitoring time reaches the specified range, remove the device from the water environment, then unscrew the sealing base (25), take out the water samples in the multiple storage bottles (29), mark them and send them to the laboratory for other tests. Combined with the pH value test results and conductivity test results during use, multiple monitoring results of the water body in the water environment can be obtained, thereby improving the accuracy of the overall monitoring results and facilitating the judgment of the water quality of the water environment at different times based on the water body test results at different time periods.
