Description

Technical Field

[0001] The utility model relates to the technical field of stepless multi-layer water sampling, in particular to a stepless multi-layer water sampling mechanism in a fidelity water environment device. Background Art

[0002] Multi-layer water extraction technology, also known as multi-point water extraction technology, is a technology that can extract water at different depths. Traditional water sampling devices can usually only collect water samples within a specific water depth range, while multi-layer water extraction devices can extract water at multiple depths through multiple water sampling layers and corresponding pipeline systems. This technology is often used in environmental monitoring, water quality analysis, and deep-water aquaculture. By collecting water samples at different depths, more comprehensive and accurate water quality data can be obtained to better understand the growth of microorganisms, the distribution and changes of water components. It can help monitor and identify microorganisms, pollutants, nutrients and other related parameters in water bodies. The implementation of multi-layer water extraction technology usually requires the design of a suitable pipeline system and corresponding water extraction equipment to ensure that water samples collected at different depths do not interfere with or mix with each other.

[0003] There are many different methods for multi-layer water extraction. The patent comparison analysis is as follows:

[0004] A deep water sampling device for enterprise water quality monitoring and its use method, CN114526957A, discloses a deep water sampling device for enterprise water quality monitoring and its use method, belonging to the field of water quality monitoring, which includes a rod and a storage component, so that the adsorbent can store the water to be tested in the sampling component through the rod to achieve rapid sampling of water quality, and at the same time, through the assembly of multiple storage components and rods, the design enables the sampling component to sample water quality at different depths to achieve multiple sampling of water quality, thereby effectively improving the sampling efficiency of the sampling device. Although this device can be lifted and lowered once to extract water from multiple layers, the number of water extraction layers is affected by the number of storage components, and the amount of water extracted from each layer is affected by the volume of the storage component. When the number of layers to be extracted is large and the amount of water extracted from each layer is large, more storage components are required and the volume of the storage components is large, which will cause the volume and weight of the entire device to increase. Moreover, it can only be used for extracting water in an open environment, and cannot be used for extracting water in a fidelity water environment.

[0005] Water body buoy profile sampling device and method, CN102680279B, provides a water body buoy profile sampling device and method, the device includes an electronic cabin unit installed inside the buoy and a profile sampling unit suspended below the buoy; the profile sampling unit includes: a profile water inlet pipe and a three-way valve installed thereon at intervals; a steel cable and a pressure sensor installed thereon, the pressure sensor and each three-way valve are installed on the same horizontal plane correspondingly; a heavy hammer connected to the end of the steel cable; the electronic cabin unit includes: a flow meter connected to the profile water inlet pipe; a water quality measurement chamber connected to the flow meter; a pumping device connected between the flow meter and the water quality measurement chamber; a data acquisition module connected to the pressure sensor, the pumping device and the water quality measurement chamber, controls water sample collection, depth measurement and water quality analysis, and records measurement data; a solar power supply system powers the entire sampling device. However, it cannot take water at any depth, but can only take water at several fixed depths; multiple valves and pressure sensors must also be arranged, which is costly.

[0006] A portable stratified water extraction device, CN216012859U, provides a portable stratified water extraction device, including an air extraction device, a main air pipe, a pull rope, a water pump, a float and a lead sinker. By changing the connection position of the float on the pull rope, the water entry depth of the lead sinker is adjusted, and air is extracted through the air pump, and negative pressure appears on the upper part of the water pump body, so that water enters the water pump. The water pump is fixed to the pull rope by a buckle, and the water extraction of different layers is controlled by changing the fixed position of the water pump and the pull rope and the number of water pumps. However, multiple water pumps are required and the depth of the water pumps needs to be adjusted. The amount of water extracted is limited by the volume of the water pump, and water cannot be extracted in a authentic water environment.

The ball screw module 311 converts the rotation of the waterproof motor 313 into linear motion, so that motion at different depths can be achieved;

[0038] One side of the second support plate 31124 is connected to the first support plate 2. The ball screw module 311 is fixed on the first support plate 2.

[0039] The guide rail unit 32 is provided with a slide rail 321, and a second slider 322 is provided on the slide rail 321. One side of the second slider 322 is connected to one side of the first slider 312. When the first slider 312 moves up and down, it guides the first slider 312 to prevent the first slider 312 from rotating.

[0040] A third support plate 5 is provided at the bottom of the waterproof motor 313 and is connected to the first support plate 2 to support the waterproof motor 313 .

[0041] A water intake device 4 is provided on one side of the guide device 3, and a water intake valve 41 is provided on the water intake device 4 on the first slider 313. A water guide pipe 42 is provided at one end of the water intake valve 41, and a sealing tube 43 is provided at one end of the water guide pipe 42 and is located in a first through hole 6 provided on one side of the outer shell 1. A flow meter 44 and a water intake valve 45 are provided in sequence at one end of the sealing tube 43.

[0042] When taking water, open the water inlet valve 41 and the water outlet valve 45. When the volume of the outflowing water is greater than the volume of the water pipe 42, the water intake container can be placed at the water outlet of the water outlet valve 45.

[0043] A displacement sensor 9 and a differential pressure sensor 10 are disposed on one side of the first slider 312, and a temperature sensor 11, a pressure sensor 12 and a salinity sensor are disposed on the inner side of the housing 1. When a portion of the sample water is taken away, the temperature, pressure and salinity of the sample water in the housing may change, and real-time monitoring is required to ensure that the sample water always maintains the same state.

[0045] Here’s how it works:

[0046] S1. Determine the depth of water sampling. After determining the target depth, start the waterproof motor 313. The water inlet valve 41 moves along the slide rail 321 along with the first slider 312 and the second slider 322. The depth of the water inlet valve 41 is determined by the displacement sensor 9 on the same plane as the water inlet valve 41. Adjust the waterproof motor 313 to make the water inlet valve 41 reach the target depth of water sampling.

[0047] S2. After reaching the target depth, the water inlet valve 41 and the water outlet valve 45 are opened successively to drain water. During the drainage, the pressure sensor 12 detects the pressure fluctuation. The multi-layer water intake system in the authentic water environment device will automatically replenish the seawater of the same temperature and salinity in the housing 1 through the one-way valve 8;

[0048] S3, when the control system recognizes that the flow rate through the flow meter 44 is greater than or equal to the volume of the water pipe 42, that is, the original water in the water pipe 42 has been drained, the water outlet valve 45 is automatically closed;

[0049] S4, after standing still, take the container containing the water sample to the water outlet valve 45, then open the water outlet valve 45 to let the water sample of the target depth flow out, and detect the pressure fluctuation through the pressure sensor 12 when taking water. The multi-layer water intake system in the fidelity water environment device will automatically replenish the seawater of the same temperature and salinity in the shell through the one-way valve 8. After taking enough water samples, the water outlet valve 45 and the water inlet valve 41 are closed in turn;

[0050] S5. When it is necessary to continue taking water samples at different depths, repeat steps S1 to S4.

[0051] Therefore, the utility model adopts the above-mentioned stepless multi-layer water sampling mechanism in the authentic water environment device to realize multi-layer water sampling at any position in the high-pressure authentic water environment device, and the pressure range can be 0-30MPa; realize pressure-maintaining control of water sampling; and ensure that each water sampling layer is free from contamination by old water from other layers.

[0052] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in this field should understand that they can still modify or replace the technical solution of the utility model with equivalents, and these modifications or equivalent replacements cannot cause the modified technical solution to deviate from the spirit and scope of the technical solution of the utility model.
