Description

Technical Field

[0001] This utility model relates to the field of water quality monitoring technology, and in particular to a water quality testing and sampling device. Background Technology

[0002] Water quality monitoring is the process of monitoring and measuring the types of pollutants in water bodies, the concentrations of various pollutants, and their changing trends, in order to evaluate the water quality status.

[0003] In the prior art, utility model application CN219830429U provides a river water quality sampling device, including a sampling tube, a sleeve is sleeved at the inlet of the sampling tube, a filter plate is installed at the end of the sleeve away from the sampling tube, and an mounting plate is fixedly installed on the sampling tube. The mounting plate is provided with a connecting component for connecting the sleeve. This application has the effect of reducing the possibility of some large impurities entering the water pump, thereby reducing the possibility of water pump damage.

[0004] However, in the actual production and processing process, the applicant found that when using traditional sampling containers to collect water samples, it is usually necessary to operate manually or use simple mechanical equipment to obtain samples from a specific water depth. This method has obvious limitations when continuously sampling samples from waters at different depths. It cannot achieve automated, continuous, multi-level sampling, resulting in long sampling time and low efficiency. Furthermore, improper operation may affect the accuracy and representativeness of the samples. Therefore, this application provides a water quality testing sampling device to meet the needs. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies and provide a water quality testing and sampling device.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a water quality testing and sampling device, comprising a buoy body and a support platform, wherein a water quality sampling component is provided on the support platform, the water quality sampling component includes a sampling tank, a transparent plate is embedded in the sampling tank, a scale is provided on the transparent plate, a knob groove is provided on the sampling tank, a tank lid is movably connected to the top of the sampling tank, a flip plate is movably connected to the top of the tank lid, a second rotating shaft is provided through the flip plate, and the two ends of the second rotating shaft are movably connected to the tank lid.

[0007] In a preferred embodiment, the bottom of the sampling container is provided with a lifting assembly, which includes an automatic telescopic rod. A first rotating shaft is movably connected to the automatic telescopic rod, and a rotating cover plate is fixedly connected to the first rotating shaft. The rotating cover plate has a slot and is located on the top of the container lid. A base is fixedly connected to the bottom of the automatic telescopic rod, and a fixing groove is movably connected to the bottom of the sampling container. The fixing groove is fixedly connected to the base.

[0008] The technical effect of adopting the above-mentioned further solution is as follows: After sampling, the automatic telescopic rod drives the device to gradually move upward. When the bottom of the base is higher than the height of the platform opened in the support, the compression of the limit block disappears and it pops out under the elastic action of the spring. At this time, the bottom of the spring is locked in the platform opened in the support, so that the device will not descend again.

[0009] In a preferred embodiment, the sampling container is provided with a filter plate, and a lifting handle is movably connected to the filter plate.

[0010] The technical effect of adopting the above-mentioned further solution is that after the sample is taken out, the can lid can be unscrewed, the pull handle can be pulled out to remove the water quality sampling component, and the pollutants intercepted on the sampling tank and filter plate can be cleaned to ensure the cleanliness of the sampling tank. This prevents the residual substances in the sampling tank from contaminating the samples of other water areas when the device is used to collect samples from other water areas, thus affecting the sample detection results and detection efficiency.

[0011] In a preferred embodiment, the base is provided with a snap-fit ​​assembly, the snap-fit ​​assembly includes a groove, a third rotating shaft is provided in the groove, the third rotating shaft passes through the limiting block and is movably connected to the base at both ends, a spring is fixedly connected to the end of the limiting block near the fixing groove, and the end of the spring away from the limiting block is fixedly connected to the base.

[0012] The technical effect of adopting the above-mentioned further solution is as follows: After sampling, the automatic telescopic rod drives the device to gradually move upward. When the bottom of the base is higher than the height of the platform opened in the support, the compression of the limit block disappears and it pops out under the elastic action of the spring. At this time, the bottom of the spring is locked in the platform opened in the support, so that the device will not descend again.

[0013] In a preferred embodiment, a support frame is fixedly connected to the buoy body, a fixed connecting block is fixedly connected to the top intersection of the support frame, the top of the automatic telescopic rod passes through the fixed connecting block and is fixedly connected to the output end of the motor, and a traction rope is fixedly connected to one side of the buoy body.

[0014] The technical advantage of adopting the above-mentioned further solution is that after all sampling work is completed, the staff can pull the tow rope 7 to pull the entire sampling device back to the shore and take out the water quality sampling component 5 for testing, thus realizing the recycling of the device and avoiding resource waste.

[0015] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0016] This invention incorporates a water sampling component and a lifting component. The operator pushes the device into the water area to be tested. Upon reaching the designated location, the automatic telescopic rod extends downwards, causing the lifting component and water sampling component to move downwards as a whole. Once the desired water level is reached, the motor is activated, causing the first rotating shaft to rotate at a certain angle. At this point, the slot and the flap are on the same vertical line. Under water pressure, one side of the flap folds inwards towards the tank cover, allowing water at that height to gradually fill the sampling tank. After a period of time, the motor is activated again. During the slot's movement, the rotating cover pushes the flap back to its original position, preventing water from overflowing from the sampling tank. As the rotating cover moves, the automatic telescopic rod also moves upwards to a higher height, and the slot gradually moves to the top of the flap on the next sampling tank, repeating the above process. This allows the device to collect samples from different water levels, whether rivers, lakes, or oceans, accurately capturing the required samples, greatly improving sampling efficiency and accuracy, and expanding its applicability and work efficiency.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] like Figure 1 - Figure 4As shown, this embodiment provides a technical solution: a water quality testing and sampling device, including a buoy body 1 and a support platform 2. A water quality sampling component 5 is provided on the support platform 2. The water quality sampling component 5 includes a sampling tank 51, a transparent plate 52 embedded in the sampling tank 51, a scale 53 provided on the transparent plate 52, a knob groove 54 on the sampling tank 51, a tank cover 57 movably connected to the top of the sampling tank 51, a flip plate 58 movably connected to the top of the tank cover 57, and a second rotating shaft 5 through the flip plate 58. 9. The two ends of the second rotating shaft 59 are movably connected to the tank cover 57. A lifting assembly 4 is provided at the bottom of the sampling tank 51. The lifting assembly 4 includes an automatic telescopic rod 41. A first rotating shaft 43 is movably connected to the automatic telescopic rod 41. A rotating cover plate 44 is fixedly connected to the first rotating shaft 43. The rotating cover plate 44 has a slot 45. The rotating cover plate 44 is located on the top of the tank cover 57. When the operator pushes the device into the water area to be tested, after reaching the designated location, the automatic telescopic rod 41 extends and retracts downwards. The lever 41 drives the lifting assembly 4 and the water quality sampling assembly 5 to move downwards as a whole. After reaching the height of the water area to be measured, the motor 42 is turned on. The motor 42 drives the first rotating shaft 43 to start rotating at a certain angle. At this time, the slot 45 and the flap 58 are on the same vertical line. Under the pressure of the water, one side of the flap 58 folds inwards towards the inside of the tank cover 57, so that the water at this height gradually flows into the sampling tank 51. After a period of time, the motor 42 is turned on again. During the movement of the slot 45, the rotating cover 44 pushes the flap 58 to fold back to its original position to prevent the water in the sampling tank 51 from overflowing. As the rotating cover 44 moves, the automatic telescopic lever 41 also begins to move upwards to a higher height. The slot 45 gradually moves to the top of the flap 58 on the next sampling tank 51 and repeats the above process. This allows the device to collect samples at different water heights. Whether it is a river, lake or ocean, it can accurately capture the required sample, greatly improving the sampling efficiency and accuracy, and expanding its application range and working efficiency.

[0029] Furthermore, such as Figure 1 - Figure 2 As shown: The bottom of the automatic telescopic rod 41 is fixedly connected to the base 46, and the bottom of the sampling tank 51 is movably connected to the fixing groove 47. The fixing groove 47 is fixedly connected to the base 46. The automatic telescopic rod 41 drives the water quality sampling component 5 on the fixing groove 47 to move downward, assisting in completing the sampling process of the device at different heights of the water area to be tested.

[0030] The above solutions also raise the question of how to prevent the residue of samples from remaining in different water bodies, such as... Figure 4As shown: In this scheme, a filter plate 55 is installed inside the sampling tank 51, and a lifting handle 56 is movably connected to the filter plate 55. After the sample is taken out, the tank cover 57 can be unscrewed, and the lifting handle 56 can be pulled to take out the water quality sampling component 5. The pollutants intercepted on the sampling tank 51 and the filter plate 55 are cleaned to ensure the cleanliness of the sampling tank 51. This prevents the substances remaining in the sampling tank 51 from contaminating the samples of other water bodies when the device is used to collect samples from other water bodies, which would affect the sample detection results and detection efficiency.

[0031] The above solutions still have the problem of how to fix the device, such as... Figure 4 As shown: In this scheme, a snap-fit ​​component 6 is provided on the base 46. The snap-fit ​​component 6 includes a groove 61, and a third rotating shaft 63 is provided in the groove 61. The third rotating shaft 63 passes through the limiting block 62 and is movably connected to the base 46 at both ends. A spring 64 is fixedly connected to the end of the limiting block 62 near the fixing groove 47. The end of the spring 64 away from the limiting block 62 is fixedly connected to the base 46. After sampling, the automatic telescopic rod 41 drives the device to gradually move upward. When the bottom of the base 46 is higher than the height of the platform opened in the support platform 2, the compression on the limiting block 62 disappears and it pops out under the elastic action of the spring 64. At this time, the bottom end of the spring 64 is locked in the platform opened in the support platform 2, so that the device will not descend again.

[0032] The above solutions still have the problem of how to retrieve the device, such as... Figure 1 As shown: In this scheme, a support frame 3 is fixedly connected to the buoy body 1, and a fixed connecting block 8 is fixedly connected to the top intersection of the support frame 3. The top of the automatic telescopic rod 41 passes through the fixed connecting block 8 and is fixedly connected to the output end of the motor 42. A traction rope 7 is fixedly connected to one side of the buoy body 1. After all sampling work is completed, the staff pulls the traction rope 7 on the shore to pull the entire sampling device back to the shore and takes out the water quality sampling component 5 for testing, so as to realize the recycling of the device and avoid resource waste.

[0033] Working principle:

[0034] like Figure 1-4 As shown:

[0035] In use: The operator pushes the device into the water area to be tested. After reaching the designated location, the automatic telescopic rod 41 extends downwards, causing the lifting assembly 4 and the water quality sampling assembly 5 to move downwards as a whole. Once the height of the water area to be tested is reached, the motor 42 is turned on, causing the first rotating shaft 43 to rotate at a certain angle. At this time, the slot 45 and the flap 58 are on the same vertical line. Under the pressure of the water, one side of the flap 58 folds inwards towards the tank cover 57, allowing water at this height to gradually fill the sampling tank 51. When the sampling tank... After sampling tank 51 is filled with water, it is in equilibrium with the external water. At this time, irrigation 57 maintains a horizontal state under water pressure. After a period of time, motor 42 is turned on again. During the movement of slot 45, rotating cover 44 pushes flap 58 to fold back to its original position to prevent water from overflowing from sampling tank 51. As rotating cover 44 moves, automatic telescopic rod 41 also begins to move to a higher height. Slot 45 gradually moves to the top of flap 58 on the next sampling tank 51, and the above process is repeated to achieve the device's ability to handle different water depths. The device can accurately capture the required samples, whether from rivers, lakes, or oceans, greatly improving sampling efficiency and accuracy, and expanding its applicability and work efficiency. After sampling, the automatic telescopic rod 41 drives the device to gradually move upward. When the bottom of the base 46 is higher than the platform height opened in the support platform 2, the compression on the limit block 62 disappears, and it pops out under the elastic action of the spring 64. At this time, the bottom of the spring 64 is locked in the platform opened in the support platform 2, so that the device will not descend again. At this time, the staff pulls it from the shore. The towing rope 7 pulls the entire sampling device back to the shore, and the water quality sampling component 5 is taken out for testing, realizing the recycling of the device and avoiding resource waste. After taking out the sample, the canister cap 57 can be unscrewed, and the lifting handle 56 can be pulled out to remove the water quality sampling component 5. The pollutants intercepted on the sampling tank 51 and the filter plate 55 are cleaned to ensure the cleanliness of the sampling tank 51. This prevents residual substances in the sampling tank 51 from contaminating samples from other waters when the device is used to collect samples from other waters, thus affecting the sample test results and testing efficiency. The above description is only a preferred embodiment of this utility model and is not intended to limit this utility model in other ways. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of this utility model without departing from the technical solution of this utility model shall still fall within the protection scope of this utility model.
