Description

Technical Field

[0001] The present application relates to the technical field of liquid sampling, and more specifically, to a liquid sampling device, and more particularly to a multi-specification liquid multi-layer synchronous sampler, which can perform multi-specification synchronous sampling of liquids of different depths at the same position. Background Art

[0002] In the process of manufacturing, scientific experiments and technology research and development, it is often necessary to collect some liquid samples for experimental analysis. The characteristics of liquid samples such as composition or concentration often change in vertical height. Therefore, when sampling, multiple sampling points at different depths are usually selected to obtain liquid samples at different locations and depths.

[0003] For example: in the field of hydrological observation, water samples for analyzing the chemical composition of natural water in rivers are generally sampled 0.2 to 0.5 meters below the water surface in the flow section of the hydrological station. Sampling points should be increased when the section is open. The sampling points on the shore should be set at places where the water flow is smooth. If necessary, stratified sampling can be carried out at different depths. The number of sampling times is evenly distributed in different periods and different flow rates according to the changes in water conditions. Another example: in the field of sewage treatment, as people's awareness of resource protection becomes stronger and stronger, people begin to treat polluted water resources so that sewage can be reused. Sewage sedimentation tanks are born. Stratified sampling of sewage sedimentation tanks is an indispensable step to check the water quality at different depths of sedimentation tanks.

[0004] In the prior art, special vessels or basins, buckets, etc. can be used to collect surface water samples of water bodies, and various types of liquid samplers with depth sounding equipment can be used to collect deep water samples. Most of the water quality samplers for terrestrial water bodies are bottle-type, consisting of a water collection container, a water pipeline, a depth sounding rope, etc. The water collection container uses a chemically stable glass bottle, a polytetrafluoroethylene or polyethylene plastic bottle, and the bottle mouth is equipped with a ground glass stopper or a plastic cover to prevent leakage or infiltration of impurities. The samplers for deep seawater include multi-barrel samplers, insulating samplers, and inverted samplers. The water collection containers are mostly metal copper tubes with precious metals plated on the inner wall to avoid corrosion affecting the chemical properties of the water sample. However, the existing liquid samplers have the disadvantages of complex structure, large space occupation, and inconvenient transportation. In addition, if it is necessary to sample liquids of different depths, it is necessary to perform multiple repeated sampling operations, and it is impossible to perform multi-specification synchronous sampling of liquids of different depths at the same location. The operation process is cumbersome, time-consuming and labor-intensive, and the accuracy is low.

[0005] With respect to the problem in the related art that liquid samplers are unable to perform synchronous sampling of liquids of multiple specifications at different depths at the same location, no effective solution has been proposed yet. Summary of the invention

[0045] like Figures 1 to 5As shown, the present application relates to a multi-specification liquid multi-layer synchronous sampler, which includes a sampler body 1 and a sealing baffle 2, wherein: the interior of the sampler body 1 is continuously and spaced from top to bottom with a plurality of push-pull storage tanks 8, an overflow cavity 101 is reserved above each push-pull storage tank 8, a first partition 9 is arranged between the overflow cavity 101 and the push-pull storage tank 8, a plurality of sampling containers 10 with different volumes (that is, each sampling container 10 is of multiple specifications) are fixedly placed in the push-pull storage tank 8, a plurality of guide ports 901 are opened on the first partition 9, and the overflow cavity 101 passes through each guide port 9 01 is connected with the sampling port of each corresponding sampling container 10, an opening for the push-pull storage tank 8 to be put in or taken out is arranged on one side wall of the sampler body 1, and a sealing baffle 2 that can be opened and closed is installed at the opening, and a plurality of trash racks 7 are arranged on the other opposite side wall of the sampler body 1, and the setting position of each trash rack 7 is opposite to each overflow cavity 101, and the external liquid can flow into the corresponding overflow cavity 101 through the through hole on the trash rack 7; at least one sealing plate 4 that can radially block the through hole on each trash rack 7 is arranged on the sampler body 1, and the sealing plate 4 can be movably arranged on the sampler body 1. In the process of synchronously sampling liquids at different depths, the sealing plate 4 at the corresponding depth is opened, and the liquid at each depth flows into the corresponding overflow cavity 101 through the through hole on the trash rack 7 at the corresponding depth, and the trash rack 7 can play a role in intercepting pollutants (such as large garbage) in the liquid. The liquid entering the overflow chamber 101 then flows into the sampling container 10 through the guide port 901 on the first partition 9 and the sampling port on the sampling container 10 in turn. The sampling containers 10 in the push-pull storage tanks 8 at different heights complete the synchronous sampling of liquids of different depths at the same position in multiple specifications. There is no need to repeat the sampling operation many times, which greatly improves the accuracy of multi-layer synchronous sampling of liquids. In addition, the present invention has a simple structure, small space occupation, easy transportation, and wide applicability. In addition, at least one sealing plate 4 is movably arranged on the sampler body 1. By adjusting the position of the sealing plate 4, the through holes on each trash rack 7 can be blocked, so that liquids of different depths can be collected in a targeted manner according to actual needs. It is easy to operate, saves manpower and material resources, and is conducive to sampling different regions and different liquids. The practicality and applicability are greatly improved.

[0046] In an optional embodiment of the present invention, Figures 1 to 5 As shown, the multi-specification liquid multi-layer synchronous sampler can be, but is not limited to, a four-layer structure (i.e., four push-pull storage tanks 8 are arranged from top to bottom inside the sampler body 1). Of course, the multi-specification liquid multi-layer synchronous sampler can also be set to a three-layer structure, a five-layer structure or other layer structure according to different liquid sampling depths to meet the liquid multi-layer sampling requirements.

The installation is convenient and the applicability is wider.

[0048] Specifically, Figure 6 As shown, the magnetic suction component 3 includes a magnetic base 301, a rotating handle 302 and a strong magnet. The magnetic base 301 is a rectangular box-shaped structure. The strong magnet is arranged in the magnetic base 301. The adsorption surface 304 of the strong magnet faces one side end surface of the magnetic base 301. The rotating handle 302 is arranged on the other adjacent side end surface of the magnetic base 301. One end of the rotating handle 302 is located outside the magnetic base 301, and the other end of the rotating handle 302 extends into the magnetic base 301 and is connected to the strong magnet. The magnetic suction component 3 is fastened and adsorbed to a fixed position on the hull or the shore by the adsorption surface 304 of the strong magnet, thereby fixing the sampler body 1; the direction of the adsorption surface 304 of the strong magnet can be changed by rotating the rotating handle 302, so that the sampler body 1 can be removed from the fixed position on the hull or the shore.

[0049] Further, in an optional embodiment of the present invention, the magnetic attraction assembly 3 can be fixed by but not limited to two "L"-shaped fixing plates 303, one end of the two fixing plates 303 is respectively fixedly connected to the two opposite side outer walls of the magnetic base 301, and the other ends of the two fixing plates 303 are respectively fixed to fixed positions on the hull or the shore. The connection method between the fixing plate 303 and the magnetic base 301 can be but not limited to welding.

[0050] Furthermore, in another optional embodiment of the present invention, the magnetic suction assembly can be fixed by, but not limited to, a plurality of pins, and the magnetic base 301 can be directly fixed to a fixed position on the hull or the shore by a plurality of pins.

[0051] In an optional embodiment of the present invention, Figures 1 to 3 As shown, a guide rail 6 is arranged on the outer wall of the sampler body 1 in the vertical direction, a linear push rod motor 5 is fixed to the bottom of the sampler body 1, the edge of the sealing plate 4 is slidably embedded in the guide rail 6, and the push rod of the linear push rod motor 5 is connected to the sealing plate 4. Since the liquid sampling process is carried out underwater, the staff can control the position of the sealing plate 4 by controlling the linear push rod motor 5, which is convenient to operate.

[0052] In this embodiment, Figure 2 , Figure 3As shown, there are two guide rails 6 and two linear push rod motors 5. The two guide rails are respectively arranged on both sides of each trash rack 7. The two opposite side edges of the sealing plate 4 can be slidably embedded in the corresponding guide rails 6. The two linear push rod motors 5 are located below the corresponding guide rails 6, and the push rods of the two linear push rod motors 5 are respectively connected to the bottom of the two opposite side edges of the sealing plate 4.

[0053] In this embodiment, the linear push rod motor 5 is made of waterproof material. The working state of the linear push rod motor 5 is remotely controlled by a wireless controller or a single chip controller.

[0054] In an optional embodiment of the present invention, Figure 4 , Figure 5 As shown, the sampling port is opened at the top of the sampling container 10 and communicates with the interior of the sampling container 10, the first partition 9 is arranged in the horizontal direction, the two opposite side edges of the first partition 9 are fixedly connected to the inner wall of the sampler body 1, and each guide port 901 on the first partition 9 is respectively located directly above the corresponding sampling container 10, the shape and size of each guide port 901 are the same as the shape and size of the sampling port of the corresponding sampling container 10, and the lower edge of each guide port 901 is in contact with the upper edge of the sampling port of the corresponding sampling container 10, so that each guide port 901 is exactly connected with the sampling port of the corresponding sampling container 10, ensuring that all the liquid passing through the guide port 901 enters the corresponding sampling container 10. In addition, a plurality of sampling containers 10 with different volumes are arranged at the same liquid depth position, which can meet the requirements of synchronous sampling of different liquid amounts at the same depth, thereby obtaining liquids of different specifications and avoiding the tedious operation of repeated sampling.

[0055] In this embodiment, a sealing strip is fixedly provided on the upper edge of the sampling port of the sampling container 10 , and the upper edge of the sampling port of the sampling container 10 is tightly fitted with the lower edge of the corresponding guide port 901 through the sealing strip.

[0056] In an optional embodiment of the present invention, Figure 4 As shown, the sampling container 10 may be, but is not limited to, a bottle-shaped structure arranged in the vertical direction. The sampling port of the sampling container 10 is opened at the center of the top of the sampling container 10, and an external thread is provided on the outer wall of the sampling container 10. A plurality of mounting holes 803 are opened on the inner wall of the bottom of the push-pull storage tank 8, and an internal thread is provided on the inner wall of the mounting hole 803. The lower part of each sampling container 10 is placed in the corresponding mounting hole 803, and the sampling container 10 is connected to the mounting hole 803 by the external thread and the internal thread, so as to ensure that the sampling container 10 is stably arranged in the push-pull storage tank 8, improve the stability of liquid sampling, and avoid the spillage of the sampled liquid due to the shaking of the sampling container 10 during the sampling process.

[0057] In this embodiment, the sampling port of the sampling container 10 is circular. Of course, according to the properties and viscosity of the sampled liquid, the sampling port of the sampling container 10 can be set to various shapes such as an inverted cone to drain the liquid to a certain extent, which is conducive to the liquid flowing into the sampling container 10.

[0058] In an optional embodiment of the present invention, Figure 4 As shown, the push-pull storage chamber 8 is a rectangular structure, and a plurality of sets of slide rails are respectively provided on the opposite inner walls of the sampler body 1. The two opposite edges of the bottom of the push-pull storage chamber 8 are embedded in the corresponding slide rails, so that the push-pull storage chamber 8 can slide along the extension direction of the slide rails, which is convenient for the push-pull storage chamber 8 to be pulled out or pushed in.

[0059] In an optional embodiment of the present invention, Figure 4 , Figure 5 As shown, the interior of the push-pull storage chamber 8 is divided into a plurality of accommodating chambers 802 by a plurality of second partitions 801 arranged along the vertical direction. A plurality of sampling containers 10 of the same size and shape can be fixedly placed in each accommodating chamber 802 according to the size of each accommodating chamber 802. The sampling containers 10 of different sizes and shapes are separated by the second partitions 801 to avoid collision between the sampling containers 10.

[0060] The number of sampling containers 10 placed in each accommodating cavity 802 can be set according to the volume of the sampling container 10 and the sampling amount of the sampled liquid. For example, if 25 ml and 150 ml of liquid are taken respectively, a sampling container 10 with a volume of 25 ml can be selected, and the number of sampling containers 10 set in one accommodating cavity 802 is five.

[0061] In this embodiment, a plurality of slots are provided along the vertical direction on the inner wall of the sampler body 1, and the edge of the second partition 801 can be slidably embedded in the slots, thereby fixing the second partition 801. The second partition 801 can be embedded in different slots as needed, thereby dividing into accommodating cavities 802 of different sizes, so as to set sampling containers 10 of different sizes and shapes.

[0062] Specifically, the second partition 801 is made of waterproof material.

[0063] In an optional embodiment of the present invention, the sealing baffle 2 is connected to one side edge of the opening via a plurality of hinges, a sealing strip is provided at the edge of the opening, and when the opening is closed, the sealing baffle 2 is sealed to the edge of the opening.

[0064] In an optional embodiment of the present invention, Figure 5 As shown, a handle 804 is provided on the outer wall of the push-pull storage cabin 8, and the staff can use the handle 804 to pull out or push in the push-pull storage cabin 8.

[0065] During the operation of the multi-specification liquid multi-layer synchronous sampler of the present invention: the sampler body 1 is fixedly installed on a fixed position on the hull or the shore above the sampled liquid through the magnetic suction component 3, and the sampler body 1 is lowered into the liquid, and each push-pull storage tank 8 is respectively located at a different depth position of each liquid. According to the depth of the liquid to be sampled, the staff controls the linear push rod motor 5 to adjust the sealing plate 4 of the corresponding depth to open, and the liquid at the corresponding depth flows into the corresponding overflow chamber 101 through the through hole on the trash rack 7, and then flows into the sampling container 10 through the guide port 901 on the first partition plate 9 and the sampling port on the sampling container 10 in turn, completing the synchronous sampling of liquids of different depths at the same position. After the sampling work is completed, the staff manually rotates the handle 302 to remove the sampler body 1 from the fixed position on the hull or the shore, takes the sampler body 1 out of the liquid and places it in a vertical direction, opens the sealing baffle 2, opens the corresponding push-pull storage tank 8 according to the depth of the sampling liquid required, and takes out the sampling container 10 in the push-pull storage tank 8 to obtain the sampling liquid.

[0066] From the above description, it can be seen that the present invention achieves the following technical effects:

[0067] 1. When the multi-specification liquid multi-layer synchronous sampler performs multi-specification synchronous sampling on liquids of different depths, the sealing plate 4 at the corresponding depth is opened, and the liquid at each depth flows into the corresponding overflow chamber 101 through the through hole on the trash rack 7 at the corresponding depth. The trash rack 7 can intercept pollutants in the liquid. The liquid entering the overflow chamber 101 then flows into the sampling container 10 through the guide port 901 on the first partition plate 9 and the sampling port on the sampling container 10 in turn. The synchronous sampling of liquids of different depths can be completed with only one operation, and there is no need to repeat the sampling operation multiple times, which greatly improves the accuracy of liquid multi-layer synchronous sampling. In addition, the present invention has a simple structure, occupies a small space, is easy to transport, and has a wide range of applicability.

[0068] 2. In the multi-specification liquid multi-layer synchronous sampler, a sealing plate 4 is movably provided on the sampler body 1. The through holes on each trash rack 7 can be sealed by adjusting the position of the sealing plate 4, so that liquids of different depths can be collected in a targeted manner according to actual needs. The operation is convenient, manpower and material resources are saved, and it is conducive to sampling different regions and different liquids. The practicality and applicability are greatly improved.

[0069] 3. In the multi-specification liquid multi-layer synchronous sampler, the sampler body 1 is adsorbed and fixed on a fixed position on the hull or the shore through the magnetic suction component 3. The sampler body 1 can be directly installed and fixed without the need for external special connection devices. The installation is convenient and the applicability is wider.

[0070] Fourth, in the multi-specification liquid multi-layer synchronous sampler, the position of the sealing plate 4 is adjusted by remotely controlling the linear push rod motor 5, which is convenient to operate.

[0071] 5. In the multi-specification liquid multi-layer synchronous sampler, a plurality of second partitions 801 are used to divide the push-pull storage chamber 8 into a plurality of accommodating chambers 802. The corresponding sampling containers 10 are placed according to the size of each accommodating chamber 802. The second partitions 801 can separate the sampling containers 10 to avoid collision between the sampling containers 10, thereby ensuring smooth liquid sampling.

[0072] The above description is only the preferred embodiment of the present application and is not intended to limit the present application. For those skilled in the art, the present application may have various modifications and variations.
