Description

Technical Field

[0001] The utility model relates to the technical field of samplers, and more particularly to a water resource detection sampler. Background Art

[0002] A sampler is a device used to collect gas or liquid samples, and is widely used in fields such as environmental monitoring, chemical analysis, and medical diagnosis. According to different application scenarios, there are various types of samplers. In particular, the devices used to collect liquid samples are widely used in fields such as environmental monitoring, water quality analysis, and scientific research.

[0003] As disclosed in a Chinese patent: a water resource detection sampler, application number: CN202323428197.2, includes: a sampling tube, a sampling port, a sampling head, and a disassembly screw groove. A disassembly bolt is installed on the outer wall of the sampling head, a barrier net is installed on the inner wall of the sampling port, a drain pipe is installed on the inner wall of the sampling tube, and a spherical valve is installed on the inner wall of the drain pipe. By installing a screening mechanism in the utility model, the barrier net is installed in the sampling port, and the sampling head is installed on the outer wall of the sampling port. Sediment will pass through the barrier net for filtration and will not enter the sampling tube. Subsequently, when it is necessary to discharge the filtered liquid in the sampling tube, turn the spherical valve to make the drain pipe in a flowing state, and then discharge the liquid in the sampling tube through the drain pipe, which is convenient for detection. The sediment in the water resource is filtered to avoid the situation where the sediment adheres to the sampling tube.

[0004] However, in the above technical solution, when sampling water resources, only water resources at a certain fixed depth can be sampled. Although this sampling method can reflect the situation of water resources at this depth to a certain extent, due to the fact that there are often differences in temperature, pressure, dissolved substance content, microbial distribution, etc. at different depths of the water body, therefore, it is very difficult to comprehensively and accurately reflect the actual situation of the entire water body based only on the sampling results of a single depth, resulting in poor accuracy of the data. Summary of the Utility Model

[0005] The main purpose of the utility model is to provide a water resource detection sampler, which can effectively solve the problem in the background art that when sampling water resources, only water resources at a certain fixed depth can be sampled. Although this sampling method can reflect the situation of water resources at this depth to a certain extent, due to the fact that there are often differences in temperature, pressure, dissolved substance content, microbial distribution, etc. at different depths of the water body, therefore, it is very difficult to comprehensively and accurately reflect the actual situation of the entire water body based only on the sampling results of a single depth, resulting in poor accuracy of the data.

[0006] To achieve the above purpose, the technical solution adopted by the utility model is as follows:

[0007] A water resource detection sampler, comprising a sinking base, wherein a plurality of first threaded holes are provided on the sinking base, a sampling tube is arranged in the first threaded holes, threads are arranged on the outer wall of the sampling tube, a connecting rope is arranged on the sampling tube, a floating plate is arranged on one side of the sinking base, a plurality of second threaded holes are provided on the floating plate, threaded columns are arranged in the second threaded holes, a first connecting ring is rotatably arranged on the side of the threaded column close to the sinking base, and a pulling rope is fixedly arranged on the side of the floating plate away from the sinking base.

[0008] Preferably, the number of the second threaded holes is the same as that of the first threaded holes, and the connecting rope is fixedly connected with the first connecting ring.

[0009] Preferably, the sampling tube comprises a sampling tube base, a sample storage groove is arranged on the sampling tube base, a through groove is arranged on one side of the sample storage groove, and a water inlet is arranged on the side of the sample storage groove away from the through groove.

[0010] Preferably, a piston head is arranged between the water inlet and the through groove, a second connecting ring is fixedly arranged on the side of the piston head close to the through groove, a baffle is arranged between the piston head and the water inlet, a rotating column is arranged on the baffle, and a torsion spring is arranged on the rotating column.

[0011] Preferably, the connecting rope passes through the through groove and is fixedly connected with the second connecting ring.

[0012] Preferably, the baffle is rotatably connected with the sampling tube base through the rotating column.

[0013] Compared with the prior art, the utility model has the following beneficial effects:

[0014] (1) When the utility model is used, first rotate the threaded column to adjust the position of the threaded column according to the depth of the water flow to be sampled by different sampling tubes, and then rotate the sampling tube to adjust the position of the sampling tube according to the depth of the water flow to be sampled by different sampling tubes. After the movement is completed, sink a plurality of sampling tube bases into the water through the sinking base. As the sampling tube base sinks, then use the floating plate and the pulling rope to fix the position of the second connecting ring, so that the second connecting ring will not move after sinking to a certain distance. The second connecting ring fixes the piston head, and then the sampling tube base continues to sink, separating the piston head from the baffle to sample the water flow. After the sampling is completed, the pressure between the piston head and the baffle is in a balanced state, and the torsion spring rebounds to make the baffle return to its original position, and the baffle closes the water inlet again, thereby storing the sampled water flow between the piston head and the baffle, so as to sample the water flow at different depths by using sampling tubes at different positions and ensure the accuracy of the data.

Detailed implementation manners

[0020] Next, in combination with the embodiments of the present utility model, the technical solutions in the embodiments of the present utility model will be clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0021] As Figure 1 and Figure 2 shown, a water resource detection sampler includes a sinking base 1. A number of first threaded holes 2 are provided on the sinking base 1. A sampling tube 3 is provided in the first threaded holes 2. Threads 4 are provided on the outer wall of the sampling tube 3. A connecting rope 5 is provided on the sampling tube 3. A floating plate 6 is provided on one side of the sinking base 1. A number of second threaded holes 7 are provided on the floating plate 6. A threaded column 8 is provided in the second threaded holes 7. A first connecting ring 9 is rotatably provided on the side of the threaded column 8 close to the sinking base 1. A pull rope 10 is fixedly provided on the side of the floating plate 6 away from the sinking base 1.

[0022] As Figure 3 and Figure 4 shown, in another embodiment of the present utility model, the sampling tube 3 includes a sampling tube base 301. A sample storage groove 302 is provided on the sampling tube base 301. A through groove 303 is provided on one side of the sample storage groove 302. A water inlet 304 is provided on the side of the sample storage groove 302 away from the through groove 303;

[0023] A piston head 305 is arranged between the water inlet 304 and the through groove 303. A second connecting ring 306 is fixedly arranged on one side of the piston head 305 close to the through groove 303. A baffle 307 is arranged between the piston head 305 and the water inlet 304. A rotating column 308 is arranged on the baffle 307, and a torsion spring 309 is arranged on the rotating column 308. When it is necessary to put the sampling tube 3 into the water, the sampling tube base 301 is sunk into the water by sinking the base 1. The sampling tube base 301 sinks, and then the position of the second connecting ring 306 is fixed by using the floating plate 6 and the pull rope 10. The second connecting ring 306 fixes the piston head 305. Then the sampling tube base 301 continues to sink, so that the piston head 305 is separated from the baffle 307, and the piston head 305 no longer presses the baffle 307. At the same time, the pressure between the piston head 305 and the baffle 307 becomes smaller. Then the water at the water inlet 304 presses the baffle 307, and the baffle 307 rotates around the rotating column 308, and the torsion spring 309 deforms, releasing the block of the baffle 307 on the water inlet 304, so that the water flow enters between the piston head 305 and the baffle 307, thereby sampling the water flow. After the sampling is completed, the pressure between the piston head 305 and the baffle 307 is in an equilibrium state, and the torsion spring 309 rebounds, so that the baffle 307 returns to its original position, and the baffle 307 closes the water inlet 304 again, thereby storing the sampled water flow between the piston head 305 and the baffle 307.

[0024] The second connecting ring 306 drives the piston head 305 to move, so that the piston head 305 moves towards the through groove 303, and then

[0025] The working principle of this water resource detection sampler:

[0026] In use, first rotate the threaded column 8 and adjust the position of the threaded column 8 according to the depth required for sampling by different sampling tubes 3, so that the threaded column 8 moves closer to or away from the sinking base 1. Then rotate the sampling tube 3 and adjust the position of the sampling tube 3 according to the depth required for sampling by different sampling tubes 3, so that the sampling tube 3 moves closer to or away from the floating plate 6. After the movement is completed, sink a number of sampling tube bases 301 into the water through the sinking base 1. As the sampling tube base 301 sinks, use the floating plate 6 and the pull rope 10 to fix the position of the second connecting ring 306, so that the second connecting ring 306 stops moving after sinking a certain distance. The second connecting ring 306 fixes the piston head 305. Then the sampling tube base 301 continues to sink, separating the piston head 305 from the baffle 307. The piston head 305 no longer presses the baffle 307. At the same time, the pressure between the piston head 305 and the baffle 307 becomes smaller. Then the water at the water inlet 304 presses the baffle 307, and the baffle 307 rotates around the rotating column 308, deforming the torsion spring 309 and releasing the blockage of the water inlet 304 by the baffle 307, allowing water to flow into the space between the piston head 305 and the baffle 307, thereby sampling the water flow. After the sampling is completed, the pressure between the piston head 305 and the baffle 307 is in a balanced state, and the torsion spring 309 rebounds, causing the baffle 307 to return to its original position and the baffle 307 to block the water inlet 304 again, thus storing the sampled water flow between the piston head 305 and the baffle 307. Therefore, sampling of water flows at different depths is carried out using sampling tubes 3 at different positions to ensure the accuracy of the data.

[0027] Obviously, the above embodiments of the present utility model are merely examples for clearly illustrating the present invention, rather than limitations on the implementation manners of the present invention. For those of ordinary skill in the art, based on the above description, other different forms of changes or variations can be made. It is impossible to list all the implementation manners here. Any obvious changes or variations derived from the technical solutions of the present invention still fall within the protection scope of the present invention.
