Abstract
Description
Technical Field
[0001] The present application relates to an in-situ water sample collection system for marine subsurface water bodies, in particular to a multi-tube collection system for in-situ water samples in marine subsurface water body laser profile remote sensing verification. Background Art
[0002] With the rapid development of remote sensing technology, ocean satellite remote sensing inversion technology has gradually entered the research level of stereoscopic observation of the longitudinal depth of the ocean from the sea surface water color. In the stereoscopic observation of the longitudinal depth of the ocean, the more advanced remote sensing means is water laser profile detection. The inversion technology of ocean depth profile information must rely on experimental verification. Since the water laser profile detection technology is still in the initial research stage, according to literature retrieval, the current experimental verification method is usually: a portable self-contained ocean real-time in-situ water parameter measuring instrument, which is accompanied by a submersible or sunk by a mother ship to enter the underwater operation. However, due to the high water depth and high water pressure, the instrument manufacturing process is required to be high, so the cost is very expensive; at the same time, the underwater real-time portable self-contained in-situ measurement instrument is restricted by technological development, and the parameters and accuracy of the water quality that can be measured are limited. In addition, it is risky to carry out experimental operations directly at sea with expensive instruments. Some water parameters are calculated by measuring the backscatter spectrum. There is a certain gap in accuracy and stability between on-site detection and laboratory analysis instrument measurement. At present, the implementation methods of seawater sampling and analysis are relatively mature. One sampling method is to sink the sampler into the water to a predetermined depth, open the sampler door manually or electrically to take water, and then lift the sampler to the ship for instrument detection after closing the door. The depth is usually within 10 meters, and the maximum depth is 50 to 60 meters. In addition, only 500-1000ml is sampled each time. If the sampling is not enough, re-sampling is required. The operation is also troublesome and risky at a large depth. Another sampling method is to complete it through pipes and water pumps, but due to the use of water pumps, the microorganisms in the sample water will change their natural grouping morphology and distribution state under the action of mechanical force, and mechanical agitation may affect the sample water temperature and composition (such as the introduction of residual impurities in the water pump). This distortion will have a serious impact on water sample analysis. Summary of the invention
[0003] This application aims to address the above-mentioned problems existing in the in-situ water sampling for the existing marine water depth profile component verification. By artificially creating the seawater pressure differential potential energy and utilizing the seawater pressure differential potential energy and the seawater flow characteristics, the seawater pressure differential potential energy is converted into the kinetic energy of the seawater flow. The in-situ water samples at the test point are automatically lifted to the sea surface through a special water sampling pipe using the kinetic energy of the seawater flow, thereby reducing the difficulty of obtaining deep water samples and facilitating remote sensing scientific research to accurately obtain a large number of water samples for deep analysis.
[0004] The technical solution adopted by the present application to solve the above technical problems includes: a multi-tube in-situ water sample collection system for sub-surface water bodies in the ocean, characterized in that the multi-tube in-situ water sample collection system for sub-surface water bodies in the ocean includes a weight, a flexible water intake pipe, a safety rope, a water pump, and an operation chamber. The upper part of the flexible water intake pipe is sealed and connected to the operation chamber and connected to the atmosphere. The operation chamber is partially sunk into the seawater so that the minimum seawater pressure difference (from the sea level to the highest position of the flexible water intake pipe in the operation chamber) is satisfied to extract seawater through the flexible water intake pipe to the operation chamber for Operation, the operating chamber is sealed on all sides, and the water intake position at the bottom of the flexible water intake pipe is aligned with the set water intake depth; the upper end of the safety rope is installed at the bottom of the operating chamber, the flexible water intake pipe is fixed on the safety rope, and the lower end of the safety rope is hung with a heavy hammer. The water pump is installed in the operating chamber, and a wastewater tank is arranged at the lower part of the operating chamber. The flexible water intake pipe has multiple flexible inner tubes (more than two), and the lower end of each flexible inner tube is a water inlet, which is aligned with the set water intake position. The upper part of each flexible inner tube has a water outlet, and the water outlet is located in the operating chamber. This application uses the seawater pressure difference to perform the water intake operation at the set water intake position after the flexible water intake pipe sinks to each water inlet corresponding to the set water intake position (depth). It is simple, convenient, low-cost, and the water intake is relatively stable. It does not require power drive, and the sample water is not stirred by the water pump. The microorganisms and water temperature in the sample water are not affected, and it is not easy to introduce residual impurities in the water pump, and the water sample has a high degree of fidelity.

DETAILED DESCRIPTION
[0012] The present application will be further described in detail below in conjunction with the accompanying drawings and through examples. The following examples are intended to explain the present application but the present application is not limited to the following examples.
[0013] See also Figure 1 to Figure 3 The basic structure of the embodiment of the present application is composed of five parts: a weight 1, a flexible water intake pipe 2, a safety rope 3, a water pump 4, and an operating chamber 6. The core idea of the present application is to design a flexible water intake pipe 2, the upper part of which is sealed and connected to the operating chamber 6, and the lower part of the operating chamber 6 is controlled by the mother ship's rope to sink into the sea water to a specified depth, and the minimum seawater pressure difference H between the sea level and the highest water intake position set in the operating chamber 6 (the highest position of the flexible water intake pipe 2) can meet the requirements of obtaining seawater through the flexible water intake pipe 2 and the time spent meets the requirements), the operating chamber 6 is sealed on all sides and seawater will not enter, the upper part of the operating chamber 6 is connected to the atmosphere, and is connected to the atmosphere through the upper end of the flexible water intake pipe 2, the water intake position (water inlet) of the lower part of the flexible water intake pipe 2 is aligned with the set water intake depth, and the water intake depth is controlled and connected, and the artificial Create seawater pressure difference potential energy to ensure that sufficient seawater pressure difference is formed to drive deep seawater to be lifted into the operating chamber 6. At the same time, the structural design ensures that the operating chamber 6 will not allow seawater to enter the operating chamber 6 while the seawater pressure difference is formed; the upper end of the safety cable 3 is connected to the bottom of the operating chamber 6, and the flexible water intake pipe 2 is fixed on the safety cable 3, which can be conveniently stored and operated as the safety cable 3 is retracted and released. The lower end of the safety cable 3 is hung with a heavy hammer 1 to ensure that the safety cable 3 and the flexible water intake pipe 2 are basically vertical to the water surface during operation; the function of the water pump 4 is to pump the excess water in the wastewater tank 63 into the sea or transport the sampled water to the mother ship (when there is no requirement for stability in water sample collection).
[0014] The flexible water intake pipe 2 described in the present application is in the form of multiple pipes, which is convenient for taking water from multiple water intake depths at the same time.
[0015] The flexible water intake pipe 2 of the multi-pipe structure includes a plurality of flexible inner pipes 21 (e.g., 21-1, 21-2 ... 21-N, more than two), each of which is made of a flexible heat-insulating material, and the flexible inner pipes 21 are filled with heat-insulating material 7 to ensure that the temperature of the flowing water in each flexible inner pipe 21 has little mutual influence and can be ignored. The lower end of each flexible inner pipe 21 is a water inlet, and the upper end of the flexible inner pipe 21 is introduced into the operation chamber 6 but the height is not higher than the highest water intake position, and can be directly connected to the corresponding detection instrument (e.g., a portable water quality analyzer). This embodiment utilizes the special structure of the mutual insulation of each flexible inner pipe and the lower end corresponding to the water inlet of different depths. At a geographical location, the acquisition of multiple water samples of different depths in the vertical direction of the location can be realized at the same time. Due to the thermal insulation between the flexible inner pipes, the temperature of the water samples does not interfere with each other. After a period of water discharge, the real-time true value of the water temperature of each depth layer can be obtained. The advantages of this structure are: the flexible water intake pipe 2 can simultaneously obtain water samples of multiple water depths at different water depths in a single sinking, and the efficiency is high.
[0016] The upper end of the flexible inner tube 21 of the present application is provided with an opening and closing mechanism for opening or closing the water outlet of the flexible inner tube 21 , for example, by clamping or releasing the upper end of the flexible inner tube 21 with a clamp.
[0017] The collection method of the embodiment of the present application is as follows:
[0018] S1: The lower part of the operating chamber 6 sinks to a set depth, so that the lower end of each flexible inner tube 21 corresponds to the set water depth;
[0019] S2: After a period of stable water intake, it is ensured that the seawater coming out of the upper end of each flexible inner tube 21 is the seawater of the lower water inlet;
[0020] S3: Connect the water outlet of each flexible inner tube 21 to the corresponding detection instrument for water collection and detection, and close the flexible inner tube 21 after water collection;
[0021] S4: After all the detection instruments (the number is the same as the number of the flexible inner tubes 21) have been tested, the excess seawater is discharged into the wastewater tank 63, and all the tests are completed.
[0022] After the water sample is collected in the operation chamber 6, the operator can directly use a portable water quality analyzer to measure the water temperature and related water quality parameters of the water sample in real time. After the test is completed, the excess water is pumped to the sea through the water pump 4. If accurate analysis is required on the mother ship, it is only necessary to equip the micro relay pump, connect the water inlet of the relay pump with the outlet of the flexible inner tube 21, and the sampled water can be lifted to the mother ship, or directly transported to the mother ship by the water pump 4. During the specific experimental operation, the counterweight is added to the operation chamber 6 and the mother ship's hoisting cable is coordinated and controlled to sink the operation chamber 6 to ensure that the minimum seawater pressure difference H has sufficient capacity to lift the deep seawater to normal operation.
[0023] The core idea of this application is to utilize the flow characteristics of water and the energy conversion of seawater pressure difference (the potential energy of seawater pressure difference is converted into the kinetic energy of seawater flow), and to directly lift deep seawater to the sea surface by designing a flexible water intake pipe, thereby solving the engineering problem of in-situ water intake in satellite laser remote sensing verification experiments and the problem of distortion of certain parameters of water samples that may be caused by the use of a water pump. The in-situ water sample multi-tube collection system of the marine subsurface water body of this application has a simple structure, low cost, and is easy to use. A single sinking operation can obtain water samples of the entire detection depth water layer, with high efficiency, and the amount of sample water collected is not limited, reducing the influencing factors of water sample parameter distortion. The collected water samples can be used for real-time detection by portable instruments, and can also be accurately analyzed by professional analysis instruments for related water parameters. Since the in-situ water samples are obtained, the portable detector can also be compared and calibrated. This application can also avoid the risk of expensive instruments entering the sea for real-time operation.
