Description

Technical Field

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

[0002] River management has always been a hot topic in water environment management, and water quality testing is an important part of the water environment management process. In water quality testing, it is required to accurately extract water samples at specific time and spatial locations. When sampling deep water, it is often necessary to sample multiple layers according to the depth gradient, and then conduct laboratory testing on the sampled water samples. Although laboratory testing has high accuracy, it has poor real-time performance, complex processes, insufficient accuracy, and is prone to secondary pollution. With the development of sensors and electronic technology, on-site water quality analyzers for lakes and other water bodies have emerged, which have high accuracy and can detect water quality in real time.

[0003] The determination of microorganisms in water is an important part of water quality testing. It is used to evaluate the biological activity and pollution level of microorganisms in water. Water is a natural environment where microorganisms are widely distributed. Therefore, microbial testing has become an important part of water quality environmental testing. The number and type of microorganisms in water have a certain relationship with the water pollution status. Water quality microbial testing provides technical support and guarantee for environmental quality evaluation, environmental sanitation supervision, and environmental management. It has important significance and value, but during the test, people need to carry the testing instruments to the testing site, which consumes a lot of manpower.

[0004] With the development of wireless sensor networks, people have proposed an online real-time water quality monitoring system based on wireless sensor networks. The nodes deployed in the monitored waters self-organize into a wireless network. The nodes collect water quality data and transmit it back to the data center via wireless or GPRS. In order to meet the construction of the water quality monitoring system, water quality detection devices need to be deployed in a large number of waters.

[0005] However, when using a water quality detection device to collect river water of different depths for detection, bacteria and algae in the water will adhere to the inner wall of the water storage tank, causing these microorganisms to metabolize the nutrients in the water, produce excrement, and form a biofilm attached to the inner wall of the water storage tank. When the water quality detection device subsequently draws water, it will be mixed with the residual microorganisms from the last detection, causing the results of the water quality detection to be affected. In the process of drawing water, small fish and shrimp in the river water enter the water inlet chamber and affect the detection structure. When the collected river water needs to be discharged, it is necessary to install an additional water pump to extract and discharge the collected river water, which is more power-consuming and expensive. In addition, in the long-term use of the water quality detection device, the results obtained to prevent equipment failure are inaccurate, and manual sampling inspections are required at regular intervals at the detection points. During the sampling inspection, it is troublesome to sample water samples at a fixed depth, which requires a lot of manpower and material resources. In addition, there will be a certain gap in time and space between the sampled water samples and the water samples used by the detection equipment, and it is impossible to accurately determine whether the equipment is faulty.

[0031] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0032] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0033] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.

[0034] Secondly, the present invention is described in detail with reference to the schematic diagram. When describing the embodiments of the present invention in detail, for the sake of convenience, the cross-sectional diagrams showing the device structure will not be partially enlarged according to the general scale, and the schematic diagrams are only examples, which should not limit the scope of protection of the present invention. In addition, in actual production, the three-dimensional dimensions of length, width and depth should be included.

[0035] Reference Figures 1 to 8 , which is the first embodiment of the present invention, provides a detection method for a water quality detection device. Through the detection method of the water quality detection device, it is possible to prevent microbial residues, filter the sampled liquid, automatically drain the water, and facilitate additional sampling.

[0036] When it is necessary to sink the water tank 101 into the river water for sampling and testing, external equipment, such as a lift, is used to sink the water tank 101 to a certain depth, and the water quality testing mechanism 100 is started to sample and test the river water; When water is taken in, the cleaning and filtering mechanism 500 is activated to filter the water entering the water intake tank 101 through the water inlet pipe 107, so as to prevent some small fish and shrimp from entering the water intake tank 101 through the water inlet pipe 107 and causing interference to the water quality detection data. At the same time, the blockage on the filter sleeve 501 can be cleaned to prevent the impurities such as water plants in some water from clogging the filter sleeve 501; During the water collection process, the pressure relief mechanism 300 will be activated to release the excess pressure inside the water quality detection mechanism 100, and the stirring mechanism 600 will be activated to stir the sampled water to ensure that the microorganisms in the water are evenly distributed. When the user comes to perform manual sampling and testing regularly, an additional manual sampling device can be installed on the pressure relief mechanism 300, so that an additional water quality sample can be obtained when taking water, so that the user can compare the test data; After the water intake test is completed, the drainage mechanism 400 will be automatically started to drain water, avoiding the expensive installation of an additional water pump for drainage. At the same time, the cleaning and sterilization mechanism 200 will be started to clean and sterilize the inside of the water quality testing mechanism 100, so that the subsequent test results of the water quality testing mechanism 100 will not be affected.

[0037] Reference Figure 2 , 5 7 is a second embodiment of the present invention, which provides a drainage mechanism 400, through which automatic drainage is achieved.

[0038] The drainage mechanism 400 includes a leaking hole 401, which is provided on both sides of the bottom of the water lifting plate 106. A sealing block 402 is embedded in the leaking hole 401. The bottom of the sealing block 402 is fixedly connected to a movable plate 403. The top of the movable plate 403 is fixedly connected to a magnetic ring 404. The magnetic ring 404 is sleeved on the surface of the sealing block 402. The top of the magnetic ring 404 is fixedly connected to both sides of the bottom of the water lifting plate 106. The bottom of the sealing block 402 is fixedly connected to the bottom of the movable plate 403. The outer side of the movable plate 403 is fixedly connected to a connecting rod 405. The top passes through both sides of the top of the water lifting plate 106 and is slidably connected to the water lifting plate 106. The top of the connecting rod 405 is fixedly connected to both sides of the bottom of the scraper ring 203. The outer side of the top of the movable plate 403 is fixedly connected with a first tension spring 406. The first tension spring 406 is sleeved on the bottom of the surface of the connecting rod 405. The other end of the first tension spring 406 is fixedly connected to both sides of the bottom of the water lifting plate 106. A drainage groove 408 is provided at the bottom of the water intake tank 101. There are three drainage grooves 408 and they are equidistantly distributed. Push rods 407 are fixedly connected to both sides of the top of the water intake tank 101.

[0039] Specifically, when the water lifting plate 106 moves upward to the top, the sealing block 402 will be pushed out, so that the sealing block 402 is separated from the leakage hole 401, and then the river water sampled above the water lifting plate 106 can leak downward through the leakage hole 401, and then be discharged back into the river water through the drainage groove 408, so that the tested water can be discharged time-saving and labor-saving without installing a water pump. When the water lifting plate 106 moves downward during normal use, the tension of the first tension spring 406 will be released to drive the sealing block 402 to be inserted into the leakage hole 401 for sealing, thereby avoiding liquid leakage in the process of lifting the water plate 106. At the same time, the top of the magnetic ring 404 will be magnetically adsorbed to the bottom of the water lifting plate 106 again, thereby ensuring the stability of the sealing block 402 when sealing.

[0040] Furthermore, when the threaded sleeve 104 drives the water lifting plate 106 to continue to move upward, the water quality detector 108 completes the detection of the water quality, and then the water lifting plate 106 will approach the push rod 407, and then the push rod 407 will be inserted into the leakage hole 401, and push the sealing block 402 in the leakage hole 401 downward, and then the sealing block 402 will drive the connecting plate 303 and the connecting rod 405 to move downward, and then the sealing block 402 will be separated from the leakage hole 401, and then the magnetic ring 404 will no longer be magnetically adsorbed with the water lifting plate 106, and at the same time the first tension spring 406 will be pulled to generate tension, and then the leakage hole 401 will lose its seal, so that the river water sampled above the water lifting plate 106 can pass. The water leaks downward through the leakage hole 401 and then is discharged back into the river water through the drainage groove 408, so that the water after the test can be discharged in a time-saving and labor-saving manner without installing a water pump. When the water lifting plate 106 moves downward during normal use, the tension of the first tension spring 406 will be released, thereby driving the connecting plate 303 and the connecting rod 405 to move upward and reset. Then the connecting plate 303 will drive the sealing block 402 to be inserted into the inside of the leakage hole 401 for sealing, thereby preventing the water lifting plate 106 from leaking liquid during the water lifting process. At the same time, the top of the magnetic ring 404 will be magnetically adsorbed to the bottom of the water lifting plate 106 again, thereby ensuring the stability of the sealing block 402 when sealing.

[0041] Reference Figures 1 to 8 , which is the third embodiment of the present invention, provides a cleaning and filtering mechanism 500, through which foreign matter can be filtered and assisted in cleaning.

[0042] The cleaning and filtering mechanism 500 includes a filter sleeve 501, which is fixedly sleeved on the outside of the water inlet pipe 107, a magnetic block 502 is fixedly connected to the outside of the bottom of the movable plate 403, an iron sheet 503 is magnetically adsorbed on the outside of the magnetic block 502, a limit rod 504 is fixedly connected to the bottom of the outside of the iron sheet 503, and the outside of the front of the limit rod 504 is inclined, a spring winder 505 is fixedly connected to the bottom of the outside of the water tank 101, and a connecting rope 506 is fixedly connected to the inner side of the surface of the spring winder 505, and the connecting rope 506 is wound around the spring winder. The surface of the winder 505, the other end of the connecting rope 506 extends through the drainage groove 408 to the two sides of the bottom of the water lifting plate 106 and is fixedly connected to the water lifting plate 106, the outer side of the top of the spring winder 505 is fixedly connected with a toggle bar 507, the top of the inner side of the toggle bar 507 contacts the outer side of the filter sleeve 501, the inner side of the bottom of the spring winder 505 is fixedly connected with a positioning rod 508, the top of the outer side of the iron sheet 503 is fixedly connected with a second tension spring 509, and the other end of the second tension spring 509 is fixedly connected to the bottom of both sides of the inner wall of the water intake tank 101.

[0043] Specifically, in the process of the water lifting plate 106 moving from bottom to top, the spring winder 505 will generate torque. When the water lifting plate 106 is in a horizontal position below the water inlet pipe 107 for water intake, the torque of the spring winder 505 can be released, thereby driving the toggle bar 507 to rotate in the opposite direction. At this time, the water entering the water intake tank 101 through the water inlet pipe 107 will first be filtered through the filter sleeve 501 to prevent some small fish and shrimp from entering the water intake tank 101 through the water inlet pipe 107 and causing interference with the water quality detection data. Then, the reverse rotating toggle bar 507 can continuously toggle the outer side of the filter sleeve 501, thereby continuously cleaning the filter sleeve 501 to prevent impurities such as aquatic plants in some water from clogging the filter sleeve 501.

[0044] Furthermore, in the process of the water lifting plate 106 moving from bottom to top, one end of the connecting rope 506 will be pulled upward. Since the connecting rope 506 is wound around the surface of the spring winder 505, the spring winder 505 will be driven to rotate during the pulling of the connecting rope 506, and then the spring winder 505 will generate a torque. In the process of the spring winder 505 rotating, the toggle bar 507 and the positioning rod 508 will be driven to rotate synchronously. At this time, the outer side of the front side of the limit rod 504 is inclined, so that when the positioning rod 508 rotates, whenever it contacts the outer side of the front side of the limit rod 504, The limiting rod 504 is pushed to move inward, so that the positioning rod 508 can continue to rotate. At the same time, the tension of the second tension spring 509 can pull the limiting rod 504 to reset. In the process of the water lifting plate 106 moving downward, the pulled end of the connecting rope 506 will gradually loosen, and the torque of the spring winder 505 will drive the positioning rod 508 to rotate in the opposite direction. Since the outer side of the back of the limiting rod 504 is not inclined, the torque of the spring winder 505 cannot be released further. When the water lifting plate 106 is in the horizontal position below the water inlet pipe 107 for water intake, the water lifting plate 106 will be sealed. The block 402, the magnetic block 502 and the connecting plate 303 drive the magnetic plate to move downward to the inner side of the iron sheet 503, and then the magnetic force of the magnetic plate can be used to adsorb the iron sheet 503, and then the iron sheet 503 will drive the limiting rod 504 to move inward, and at this time the limiting rod 504 will no longer position the positioning rod 508, and then the torque of the spring winder 505 can be released, so that it can rotate to wind up the loose connecting rope 506, and at the same time the spring winder 505 will continue to drive the positioning rod 508 and the toggle bar 507 to rotate in the opposite direction, and at this time the water entering the water tank 101 through the water inlet pipe 107 The water will first be filtered through the filter sleeve 501 to prevent some small fish and shrimp from entering the water tank 101 through the water inlet pipe 107 and causing interference with the water quality detection data. Then, the reverse rotating toggle bar 507 can be used to continuously toggle the outside of the filter sleeve 501, so that the filter sleeve 501 can be continuously cleaned to prevent impurities such as water plants in some water from clogging the filter sleeve 501. When the water lifting plate 106 moves upward to reset, the magnetic plate will separate from the iron sheet 503, and then the tension of the second tension spring 509 can be used to pull the iron sheet 503 and the limit rod 504 to move outward and reset, and so on.

[0045] The remaining structure is the same as that of Example 2.

[0046] Reference Figures 1 to 3 , which is the third embodiment of the present invention, provides a pressure relief mechanism 300, through which auxiliary pressure relief is achieved and an additional water sample is stored.

[0047] The pressure relief mechanism 300 includes a pressure relief pipe 301. There are several pressure relief pipes 301 and they are distributed in a circular shape with equal distances. The pressure relief pipe 301 is connected to the water intake tank 101. A sealing plate 302 is movably connected to the top of the inner wall of the pressure relief pipe 301. Both sides of the outer side of the sealing plate 302 are fixedly connected to metal springs 305. The outer side of the metal springs 305 is fixedly connected to a connecting plate 303. The top of the connecting plate 303 is fixedly connected to both sides of the outer side of the top of the inner wall of the pressure relief pipe 301. An artificial sampling component 304 is provided on the outer side of the bottom of the inner wall surface of the pressure relief pipe 301.

[0048] The manual sampling assembly 304 includes a threaded groove 304a, which is opened on the outside of the bottom of the inner wall surface of the pressure relief pipe 301. A sampling tube 304b is arranged on the left side of the water tank 101. The pressure relief pipe 301 is connected to the top thread of the sampling tube 304b through the threaded groove 304a.

[0049] The surface of the sampling test tube 304b is covered with a protective sleeve 304c, and the surface of the protective sleeve 304c is provided with anti-skid grooves 304d, and a plurality of anti-skid grooves 304d are provided and are distributed in a circular shape with equal distances.

[0050] Specifically, when the threaded sleeve 104 drives the water lifting plate 106 to move upward, the pressure in the water intake tank 101 will be too high. Here, under the action of the internal pressure of the water intake tank 101, the sealing plate 302 will be opened outward to discharge the pressure, ensuring that the water quality detector 108 can continue to detect the sampled river water.

[0051] Specifically, when the user needs to conduct manual sampling tests regularly to confirm whether the current water quality detector 108 is damaged, the user can install a sampling test tube 304b in connection with one of the pressure relief pipes 301, so that part of the water driven by the pressure relief during the water intake process of the water intake tank 101 will flow into the sampling test tube 304b, and then test the water quality in the sampling test tube 304b to confirm whether the current water quality detector 108 is faulty. By adding the sampling test tube 304b, the sampling test tube 304b can be cleaned in time after use, thereby avoiding the presence of microorganisms from the last use in the sampling test tube 304b during subsequent use.

[0052] Specifically, when the sampling tube 304b enters the river water along with the water intake tank 101, the protective cover 304c can be used to protect the exposed surface of the sampling tube 304b, thereby improving the durability of the sampling tube 304b. By providing the anti-slip groove 304d, the user can contact through the anti-slip groove 304d, thereby increasing the friction and avoiding slipping.

[0053] Furthermore, in the process of the threaded sleeve 104 driving the water lifting plate 106 to move upward, due to the large amount of liquid above the water lifting plate 106, the pressure in the water intake tank 101 is too high. Here, under the action of the internal pressure of the water intake tank 101, the sealing plate 302 will be opened outward, and then the excess water in the water intake tank 101 will be opened outward. At the same time, the metal spring piece 305 is squeezed to generate a rebound force, thereby ensuring that the water quality detector 108 can continue to detect the sampled river water during the upward movement of the water lifting plate 106. When the water lifting plate 106 stops moving, the pressure inside the water intake tank 101 will be in a normal state. At this time, the sealing plate 302 is no longer under the pressure of being pushed outward, and then the rebound force of the metal spring piece 305 can be used to push the sealing plate 302 to reset for sealing.

[0054] Furthermore, when the user needs to perform manual sampling and testing regularly to confirm whether the current water quality detector 108 is damaged, the user can take a sampling test tube 304b, and connect the top of the sampling test tube 304b to one of the pressure relief tubes 301 through the threaded groove 304a opened on the pressure relief tube 301, so that part of the water driven by the pressure relief during the water intake tank 101 will flow into the sampling test tube 304b, and then the user can remove the sampling test tube 304b by rotation to obtain a water sample with the same water quality as the water in the sampling box. Then the user can compare the water quality data of the water sample in the sampling test tube 304b with the data detected by the water quality detector 108 in the water intake tank 101, so as to confirm whether the current water quality detector 108 is faulty. By adding the sampling test tube 304b, the sampling test tube 304b can be cleaned in time after use, so as to avoid the presence of microorganisms from the last use in the sampling test tube 304b during subsequent use.

[0055] Furthermore, when the sampling test tube 304b enters the river water along with the water intake tank 101, the protective cover 304c can be used to protect the exposed surface of the sampling test tube 304b, thereby improving the durability of the sampling test tube 304b and preventing the sampling test tube 304b from being knocked and damaged. By providing the anti-skid groove 304d, when the user needs to rotate the sampling test tube 304b, the user can contact it through the anti-skid groove 304d, thereby increasing the friction and avoiding slipping.

[0056] The remaining structures are the same as those of Embodiment 2 and Embodiment 3.

[0057] Reference Figures 1 to 8 , which is the fourth embodiment of the present invention. This embodiment is different from the third embodiment in that: this embodiment provides a water quality detection device and method.

[0058] When it is necessary to sink the water tank 101 into the river water for sampling and testing, use external equipment, such as a lift, to sink the water tank 101 to a certain depth. After sinking to the required depth, start the motor 102 to drive the threaded rod 103 to rotate, and then the threaded rod 103 will drive the threaded sleeve 104 to move downward, so that the threaded sleeve 104 drives the water lifting plate 106 to move downward, so that the horizontal position of the water lifting plate 106 is below the water inlet pipe 107, and the river water outside the water tank 101 can enter the water tank 101 through the water inlet pipe 107, and then start the motor 102 again. The threaded rod 103 is driven to rotate in the opposite direction to drive the threaded sleeve 104 to move upward, and then the threaded sleeve 104 will drive the water-lifting plate 106 to continuously lift the incoming river water upward, so that the horizontal position of the water-lifting plate 106 is above the water inlet pipe 107, and then the water-taking tank 101 is stopped. Then, the external equipment is used to lift the water intake tank 101 to the water surface, and then the motor 102 continues to start and drives the water-lifting plate 106 to move upward through the threaded sleeve 104. During the lifting process, the sampled water will contact the detection end of the water quality detector 108, and then the water quality detector 108 can detect the sampled water.

[0059] When the threaded sleeve 104 drives the water lifting plate 106 to move upward, due to the large amount of liquid above the water lifting plate 106, the pressure in the water intake tank 101 is too high. Here, the sealing plate 302 will be opened outward under the action of the internal pressure of the water intake tank 101, and then the excess water in the water intake tank 101 will be opened outward. At the same time, the metal spring piece 305 is squeezed to generate a rebound force, thereby ensuring that the water quality detector 108 can continue to detect the sampled river water during the upward movement of the water lifting plate 106. When the water lifting plate 106 stops moving, the pressure inside the water intake tank 101 will be in a normal state. At this time, the sealing plate 302 will no longer be under pressure to push outward, and then the rebound force of the metal spring piece 305 can be used to push the sealing plate 302 to reset for sealing.

[0060] When the user needs to perform manual sampling and testing regularly to confirm whether the current water quality detector 108 is damaged, the user can take a sampling test tube 304b and connect the top of the sampling test tube 304b to one of the pressure relief tubes 301 through the threaded groove 304a opened on the pressure relief tube 301, so that part of the water driven by the pressure relief during the water intake tank 101 will flow into the sampling test tube 304b. Then the user can remove the sampling test tube 304b by rotation to obtain a water sample with the same water quality as the water in the sampling box. Then the user can compare the water quality data of the water sample in the sampling test tube 304b with the data detected by the water quality detector 108 in the water intake tank 101, so as to confirm whether the current water quality detector 108 is faulty. By adding the sampling test tube 304b, the sampling test tube 304b can be cleaned in time after use, so as to avoid the presence of microorganisms from the last use in the sampling test tube 304b during subsequent use.

[0061] When the sampling tube 304b enters the river water along with the water intake tank 101, the protective cover 304c can be used to protect the exposed surface of the sampling tube 304b, thereby improving the durability of the sampling tube 304b and preventing the sampling tube 304b from being knocked and damaged. By providing the anti-skid groove 304d, the user can contact the sampling tube 304b through the anti-skid groove 304d when the user needs to rotate the sampling tube 304b, thereby increasing the friction and avoiding slipping.

[0062] When the threaded sleeve 104 drives the water lifting plate 106 to continue to move upward, the water quality detector 108 completes the water quality detection, and then the water lifting plate 106 will approach the push rod 407, and then the push rod 407 will be inserted into the leakage hole 401, and push the sealing block 402 in the leakage hole 401 downward, and then the sealing block 402 will drive the connecting plate 303 and the connecting rod 405 to move downward, and then the sealing block 402 will be separated from the leakage hole 401, and then the magnetic ring 404 will no longer be magnetically adsorbed with the water lifting plate 106, and at the same time the first tension spring 406 will be pulled to generate tension, and then the leakage hole 401 will lose its seal, so that the river water sampled above the water lifting plate 106 can pass through the leakage The water hole 401 leaks downward and then is discharged back into the river water through the drainage groove 408, so that the water after the test can be discharged in a time-saving and labor-saving manner without installing a water pump. When the water lifting plate 106 moves downward during normal use, the tension of the first tension spring 406 will be released, thereby driving the connecting plate 303 and the connecting rod 405 to move upward and reset. Then the connecting plate 303 will drive the sealing block 402 to be inserted into the inside of the leakage hole 401 for sealing, thereby preventing the water lifting plate 106 from leaking liquid during the water lifting process. At the same time, the top of the magnetic ring 404 will be magnetically adsorbed to the bottom of the water lifting plate 106 again, thereby ensuring the stability of the sealing block 402 when sealing.

[0063] As the water lifting plate 106 moves from bottom to top, one end of the connecting rope 506 is pulled upward. Since the connecting rope 506 is wound around the surface of the spring winder 505, the spring winder 505 is driven to rotate during the pulling of the connecting rope 506. Then, the spring winder 505 generates a torque. During the rotation of the spring winder 505, the toggle bar 507 and the positioning rod 508 are driven to rotate synchronously. At this time, the outer side of the front side of the limiting rod 504 is inclined so that when the positioning rod 508 rotates, it pushes the limiting rod 508 whenever it contacts the outer side of the front side of the limiting rod 504. The positioning rod 504 moves inwardly, so that the positioning rod 508 can continue to rotate. At the same time, the tension of the second tension spring 509 can pull the limiting rod 504 to reset. In the process of the water lifting plate 106 moving downward, the pulled end of the connecting rope 506 will gradually loosen, and the torque of the spring winder 505 will drive the positioning rod 508 to rotate in the opposite direction. Since the outer side of the back of the limiting rod 504 is not inclined, the torque of the spring winder 505 cannot be released further. When the water lifting plate 106 is in the horizontal position below the water inlet pipe 107 and water is taken, the water lifting plate 106 will pass through the sealing block 4. 02. The magnetic block 502 and the connecting plate 303 drive the magnetic plate to move downward to the inner side of the iron sheet 503, and then the magnetic force of the magnetic plate can be used to adsorb the iron sheet 503, and then the iron sheet 503 will drive the limiting rod 504 to move inward. At this time, the limiting rod 504 will no longer position the positioning rod 508, and then the torque of the spring winder 505 can be released, so that it can rotate to wind up the loose connecting rope 506. At the same time, the spring winder 505 will continue to drive the positioning rod 508 and the toggle bar 507 to rotate in the opposite direction. At this time, the water entering the water tank 101 through the water inlet pipe 107 First, the water will be filtered through the filter sleeve 501 to prevent some small fish and shrimp from entering the water tank 101 through the water inlet pipe 107 and causing interference with the water quality detection data. Then, the reverse rotating toggle bar 507 can be used to continuously toggle the outside of the filter sleeve 501, so that the filter sleeve 501 can be continuously cleaned to prevent impurities such as aquatic plants in some water from clogging the filter sleeve 501. When the water lifting plate 106 moves upward to reset, the magnetic plate will separate from the iron sheet 503, and then the tension of the second tension spring 509 can be used to pull the iron sheet 503 and the limit rod 504 to move outward and reset, and so on.

[0064] When the motor 102 is turned on and the threaded sleeve 104 is driven to move upward through the threaded rod 103, the water lifting plate 106 will synchronously drive the scraper ring 203 to move upward, and the scraper ring 203 can continuously scrape the surface of the inner wall of the water intake tank 101 during the movement, thereby continuously cleaning the surface of the water intake tank 101 to avoid residual excess water stains that affect subsequent detection. When the threaded sleeve 104 moves to the uppermost end, the water in the water intake tank 101 that has been detected has been discharged. At this time, the left side of the top of the threaded sleeve 104 will press the press switch 202. At this time, the purple The external sterilization lamp 201 can be turned on, and then the ultraviolet sterilization lamp 201 will generate ultraviolet light to irradiate the water lifting plate 106 and various parts inside the water intake tank 101, thereby killing a large number of microorganisms, and preventing the microorganisms in the river water from multiplying inside the water intake tank 101 during this detection, resulting in the presence of microorganisms in the water intake tank 101, causing the water during subsequent water intake to be mixed with these excess microorganisms, causing the detection result of the water quality detector 108 to be affected. The ultraviolet sterilization lamp 201 is waterproof, which increases the service life of the ultraviolet sterilization lamp 201.

[0065] The bottom of the stirring blade 601 is movably connected with the two sides of the top of the water lifting plate 106, so that the stirring blade 601 can rotate. During the upward movement of the water lifting plate 106, the water lifting plate 106 will push the stirring blade 601 to move upward synchronously, and then the stirring blade 601 will drive the spiral rod 602 to move upward, and then the surface of the spiral rod is movably connected with the inner wall of the spiral sleeve 603, so that the spiral rod 602 and the spiral sleeve 603 interact with each other. When the spiral rod 602 is subjected to sufficient driving force, the spiral rod 602 will overcome the static friction and start to rotate. Once the rotation starts, the dynamic friction will maintain this rotation state until the thrust of the water lifting plate 106 on the spiral rod 602 disappears, and the spiral rod 602 will drive the stirring blade 601 to rotate during the upward movement, and then the stirring blade 601 will continuously stir the water lifted by the water lifting plate 106, so that the microorganisms in the water above the water lifting plate 106 can be evenly distributed, thereby improving the accuracy of the detection data of the water quality detector 108.

[0066] During the rotation of the stirring blade 601, the folding stirring piece 605a will also be driven to rotate synchronously. The folding stirring piece 605a is used to increase the stirring range of the stirring blade 601, further improving the uniformity of microorganisms in the water. The folding stirring piece 605a and the folding stirring piece 605a are softly connected through the rubber sheet 605d, so that multiple folding stirring pieces 605a can be folded, so that they can be used in situations where the water lifting plate 106 is at different heights. During the rotation of the folding stirring piece 605a, the limiting piece 605b will also be driven to move along the inner wall of the annular guide rail 605c, thereby improving the stability of the folding stirring piece 605a during use.

[0067] In summary, before water sampling and testing, the sampled river water will be filtered through the cleaning and filtering mechanism 500 to clear the blockages. During the water sampling process, the pressure relief mechanism 300 will be simultaneously started to relieve the pressure, and the stirring mechanism 600 will be started to stir the sampled water to ensure that the distribution of microorganisms is sufficiently uniform. After the test is completed, the drainage mechanism 400 will be started to drain water. After drainage, the cleaning and sterilization mechanism 200 will be started to sterilize the inside of the water tank 101 with ultraviolet light.
