Description

Technical Field

[0001] This utility model relates to the field of environmental monitoring technology, and in particular to a surface water microbial sampler. Background Technology

[0002] Surface water is a vital water resource for human production and daily life, and its microbial contamination status directly affects water quality safety and ecological health. Sampling is a crucial step in surface water microbial monitoring, as the performance of the sampler directly impacts the representativeness of the sample and the accuracy of the test results.

[0003] The common manual sampling method using handheld sampling bottles cannot meet the needs of stratified sampling and analysis of water bodies at different depths. At the same time, the sampling process can easily lead to the mixing of water samples from different depths, which seriously interferes with the accuracy of the test results and cannot truly reflect the original state of microorganisms in water bodies at each depth.

[0004] Therefore, in view of the above situation, there is an urgent need to develop a surface water microbial sampler to overcome the shortcomings in current practical applications. Utility Model Content

[0005] The purpose of this utility model embodiment is to provide a surface water microbial sampler, which aims to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A surface water microbial sampler includes a sampling cylinder, a handle cover fixedly connected to the upper end of the sampling cylinder, a threaded shaft rotatably connected to the inner wall of the sampling cylinder, a rotating disk fixedly connected to the upper end of the threaded shaft through the handle cover, a plurality of evenly distributed first fixing rings fixedly sleeved on the outer wall of the sampling cylinder, a second connecting plate fixedly connected to the outer wall of each of the first fixing rings, a second fixing ring fixedly connected to the other end of the second connecting plate, and sampling bottles detachably mounted on the inner wall of each of the second fixing rings, a sliding groove formed on the side wall of the sampling cylinder, a plurality of evenly distributed sliding plates slidably connected to the inner wall of the sampling cylinder, each sliding plate corresponding to one of the first fixing rings, each sliding plate being threadedly connected to the threaded shaft, a first connecting plate fixedly connected to the outer wall of each sliding plate, the first connecting plate being slidably connected to the inner wall of the sliding groove, a fixing plate fixedly connected to the other end of the first connecting plate, a bottle stopper fixedly connected to the lower end of the fixing plate, and the bottle stopper engaging with the corresponding sampling bottle.

[0008] A further technical solution is provided, wherein a zero-degree groove is provided on the handle cover and a mark groove is provided on the rotating disk, and the zero-degree groove and the mark groove are aligned when the bottle stopper blocks the sampling bottle.

[0009] In a further technical solution, the slide plate, the first connecting plate, and the fixing plate are an integrated structure.

[0010] In a further technical solution, the first fixing ring, the second connecting plate, and the second fixing ring are an integral structure.

[0011] A further technical solution is that the outer wall of the sampling cylinder is provided with scale lines, through which the sampling depth can be observed.

[0012] In a further technical solution, the sampling cylinder is provided with multiple discharge ports.

[0013] In summary, the embodiments of this utility model have the following beneficial effects compared with the prior art:

[0014] 1. Insert the sampler into the water and observe the sampling depth through the scale lines. Collect water samples through the sampling bottle. Rotate the rotating disk to drive the threaded shaft to rotate. Then, the threaded shaft drives the slide plate to slide up and down along the inner wall of the sampling cylinder. Next, the slide plate drives the fixed plate to rise and fall through the first connecting plate. The fixed plate drives the bottle stopper to open and close the sampling bottle, thereby enabling stratified sampling of water at different depths and effectively avoiding the mixing of water samples from different depths from affecting the test results.

[0015] 2. A zero-degree groove is provided on the handle cover, and a mark groove is provided on the rotating disk. When the bottle stopper blocks the sampling bottle, the zero-degree groove and the mark groove are aligned, so that it is possible to determine whether the bottle stopper is blocking the sampling bottle by the cooperation of the rotating disk and the mark groove. The operation is simple and quick.

[0020] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit this utility model.

[0021] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0022] like Figure 1 and Figure 2 As shown, this utility model embodiment provides a surface water microbial sampler, including a sampling cylinder 1. A handle cover 2 is fixedly connected to the upper end of the sampling cylinder 1. A threaded shaft 3 is rotatably connected to the inner wall of the sampling cylinder 1. A rotating disk 4 is fixedly connected to the upper end of the threaded shaft 3 through the handle cover 2. A plurality of evenly distributed first fixing rings 13 are fixedly sleeved on the outer wall of the sampling cylinder 1. A second connecting plate 14 is fixedly connected to the outer wall of each first fixing ring 13. A second fixing ring 15 is fixedly connected to the other end of the second connecting plate 14, and the inner wall of the second fixing ring 15 can be... The sampling cylinder 1 is equipped with a sampling bottle 16. A sliding groove 11 is provided on the side wall of the sampling cylinder 1. Multiple evenly distributed sliding plates 7 are slidably connected to the inner wall of the sampling cylinder 1, and each sliding plate 7 corresponds to a first fixing ring 13. Each sliding plate 7 is threadedly connected to a threaded shaft 3. Each sliding plate 7 is fixedly connected to a first connecting plate 8 on its outer wall, and the first connecting plate 8 is slidably connected to the inner wall of the sliding groove 11. A fixing plate 9 is fixedly connected to the other end of the first connecting plate 8. A bottle stopper 10 is fixedly connected to the lower end of the fixing plate 9, and the bottle stopper 10 is connected to the corresponding sampling bottle 16.

[0023] Furthermore, the handle cover 2 is provided with a zero-degree groove 5, and the rotating disk 4 is provided with a mark groove 6. When the bottle stopper 10 blocks the sampling bottle 16, the zero-degree groove 5 and the mark groove 6 are aligned, so that it can be determined whether the bottle stopper 10 blocks and seals the sampling bottle 16 by the cooperation of the rotating disk 4 and the mark groove 6.

[0024] Furthermore, the slide plate 7, the first connecting plate 8, and the fixing plate 9 are an integral structure.

[0025] Furthermore, the first fixing ring 13, the second connecting plate 14, and the second fixing ring 15 are an integral structure.

[0026] Furthermore, the outer wall of the sampling cylinder 1 is provided with scale lines 12, through which the sampling depth can be observed.

[0027] Furthermore, the sampling cylinder 1 is provided with multiple drain ports (not shown in the figure) to accelerate the outflow of water from the sampling cylinder 1 and reduce the weight of the sampling cylinder 1.

[0028] In this embodiment of the invention, the sampler is inserted into the water, and the sampling depth is observed through the scale line 12. Water samples are collected through the sampling bottle 16. The rotating disk 4 drives the threaded shaft 3 to rotate, and then the threaded shaft 3 drives the sliding plate 7 to slide and rise along the inner wall of the sampling cylinder 1. Then, the sliding plate 7 drives the fixing plate 9 to rise and fall through the first connecting plate 8. The fixing plate 9 drives the bottle stopper 10 to open and close the sampling bottle 16, thereby enabling water sampling at different depths and allowing for stratified sampling. At the same time, it effectively avoids the mixing of water samples from different depths from affecting the test results. The handle cover 2 has a zero-degree groove 5, and the rotating disk 4 has a mark groove 6. When the bottle stopper 10 blocks the sampling bottle 16, the zero-degree groove 5 and the mark groove 6 are aligned. Thus, the rotation disk 4 and the mark groove 6 can be used to determine whether the bottle stopper 10 blocks and closes the sampling bottle 16. The operation is simple and quick.

[0029] The working principle of this utility model is as follows: the sampler is inserted into the water, and the sampling depth is observed through the scale line 12. After reaching a certain depth, the rotating disk 4 is rotated to drive the threaded shaft 3 to rotate. Then, the threaded shaft 3 drives the slide plate 7 to slide and rise along the inner wall of the sampling cylinder 1. Then, the slide plate 7 drives the fixing plate 9 to rise through the first connecting plate 8. The fixing plate 9 drives the bottle stopper 10 to rise and detach from the sampling bottle 16, thereby opening the sampling bottle 16 to sample the water. Then, the rotating disk 4 is rotated in the opposite direction to control the bottle stopper 10 to descend and block the sampling bottle 16. Then, the sampler is lifted out of the water.

[0030] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
