[0002] In the field of water quality detection, it is crucial to understand the distribution of microorganisms in water bodies. This not only helps to evaluate the health status of water bodies but also provides a scientific basis for environmental protection and water resource management.

[0003] Traditional water quality detection generally samples the sampler at different depths multiple times. This operation method requires the sampler to be dropped to the predetermined water layer depth and wait for it to stabilize before sampling. Since each sampling requires repositioning and adjustment, it is not only troublesome to operate but also has low work efficiency. Therefore, we propose a layered sampler for water quality detection to solve the above problems. Content of the Utility Model

Detailed Embodiments

[0022] To make the objectives, technical solutions, and advantages of the embodiments of the present utility model clearer, the technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model.

[0023] The present application provides a layered sampler for water quality detection, mainly used to solve the problem that in the prior art, the sampler is generally sampled in multiple times at different depths. This operation method requires the sampler to be put into the predetermined water layer depth and wait for it to stabilize before sampling. Since each sampling requires repositioning and adjustment, it is not only troublesome to operate but also has low work efficiency, and provides the following technical solutions, which will be combined below Figure 1-Figure 3 Make a detailed description:

[0024] A stratified sampler for water quality detection, comprising:

[0025] The installation frame 1 has a rectangular frame structure;

[0026] The sampling mechanism 2 is used to obtain water samples. The sampling mechanism 2 includes a mounting tube 201 fixedly arranged between the inner side walls of the mounting frame 1 at equal intervals. A filter screen 202 is arranged on the upper surface of the mounting tube 201. A slide rod 203 penetrating the mounting tube 201 is slidably inserted in the middle of the top of the mounting frame 1. Slide plugs 204 are fixedly arranged on the surface of the slide rod 203 at equal intervals. The slide plug 204 is slidably connected to the inner wall of the mounting tube 201. A spring 205 is connected between the bottom of the slide plug 204 and the inner bottom wall of the mounting tube 201. The spring 205 is sleeved on the surface of the slide rod 203. The middle of both sides of the mounting tube 201 is connected with an L-shaped tube 206 penetrating the side wall of the mounting frame 1. The other end of the L-shaped tube 206 is provided with a sampling bottle 207.

[0027] The support frame 3 is arranged at the bottom of the installation frame 1, and the height of the support frame 3 is adjustable.

[0028] Workflow Description:

[0029] When in use, the staff first moves the stratified sampler for water quality detection to the water area where sampling is required, and adjusts the height of the support frame 3 according to the actual water depth to ensure that the sampler can reach the required different depths. The staff holds the handle 5 and starts sampling by pressing the slide bar 203 downward. When the slide bar 203 is pressed, the slide plug 204 slides down in the installation cylinder 201 and squeezes the spring 205 to open the channel for the water sample to enter. After the water sample is initially filtered through the filter screen 202 on the upper side of the installation cylinder 201, it enters the interior of the installation cylinder 201. As the slide plug 204 moves downward, the water sample can be introduced into the sampling bottle 207 through the L-shaped tube 206. After the sampling is completed, release your hand. Under the action of the spring 205, the slide plug 204 moves up to block the water sample entry channel (at the filter screen 202). This can prevent the water sample from leaking. Finally, move the sampler back to the shore and take out the water sample from the sampling bottle 207 for subsequent analysis.

[0030] The stratified sampler for water quality testing is designed with a combination of an installation frame 1, a sampling mechanism 2 and a support frame 3. It can complete the sampling of multiple water layers at one time with a simple pressing action, reducing the work of repeated placement and adjustment of the sampler, reducing the difficulty of operation and labor intensity, and improving work efficiency.

[0031] like Figure 1As shown, in some embodiments, the support frame 3 includes a mounting plate 301 fixedly provided at the bottom of the mounting frame 1. Threaded rods 302 are connected to both sides of the mounting plate 301, and a tray 303 is fixedly provided at the bottom end of the threaded rod 302. More specifically, when the staff arrives at the sampling site, first adjust the height of the threaded rod 302 according to the water depth. By rotating the threaded rod 302, the position of the tray 303 can be changed, and the distance between the mounting frame 1 and the bottom of the water can be changed, thereby adjusting the water sampling depth. The design of the support frame 3 enables the stratified sampler to be applicable to water bodies of different depths, increasing the applicable range of the sampler.

[0032] As Figure 1 shown, in some embodiments, a C-shaped plate 4 is fixedly provided on the upper side of the mounting frame 1, and handles 5 are fixedly provided on both sides of the C-shaped plate 4. More specifically, when the staff arrives at the sampling site and needs to put the stratified sampler into the water, the sampler can be lifted and moved by holding the handles 5. The design of the handles 5 enables the staff to maintain a firm grip, preventing accidents or damage caused by slipping during handling. Once the sampler is placed in the appropriate position, the staff can stabilize the sampler by operating the handles 5 to perform accurate placement and sampling work.

[0033] As Figure 1 shown, in some embodiments, a spirit level 6 is embedded in the middle of the front surface of the C-shaped plate 4. More specifically, the spirit level 6 is a measuring tool used to indicate whether an object is in a horizontal state. Embedding the spirit level 6 on the C-shaped plate 4 of the stratified sampler can help the staff ensure that the sampler is horizontal during deployment, thus ensuring the accuracy and consistency of the sampling process. The spirit level 6 usually contains liquid and a bubble inside. When the sampler is completely horizontal, the bubble will be located on the marking line in the middle of the liquid. If the bubble deviates from the center mark, it means that the sampler is in an inclined state. At this time, the staff needs to adjust the position of the sampler until the bubble in the spirit level 6 aligns with the center mark to ensure that the sampler is horizontal. In water quality detection, maintaining the horizontality of the sampler is very crucial because it directly affects the collection of water samples and the accuracy of subsequent analysis. If the sampler is inclined, it may cause the mixing of water samples at different depths, thus affecting the test results. The addition of the spirit level 6 enables the operator to visually confirm the horizontal state of the sampler and make adjustments when necessary to ensure that samples from each water layer can be accurately collected.

[0034] As Figure 3As shown, in some embodiments, a pressing plate 208 is fixedly provided at the upper end of the slide bar 203, and a rubber sleeve is provided on the surface of the pressing plate 208. More specifically, the pressing plate 208 is a component fixed to the upper end of the slide bar 203, usually in the shape of a disc, and its size and shape are designed to be easy to operate by hand. The pressing plate 208 serves as a direct contact point between the operator and the sampler. Its existence enables the operator to push the slide bar 203 more conveniently and forcefully. The rubber sleeve is provided on the surface of the pressing plate 208, and its main function is to increase the friction and comfort when holding. The rubber material has excellent anti-slip properties, which can ensure that the operator's hand is not easy to slip even in a wet and slippery environment. At the same time, the rubber sleeve can also provide a certain buffer, reduce the impact on the palm during operation, and improve the comfort of operation. When the staff needs to take samples, they will hold the rubber sleeve on the pressing plate 208 with their hands and press the slide bar 203 downward. Due to the presence of the rubber sleeve, the operator's feel is more stable, which can reduce operational errors caused by hand sliding.

[0035] like Figure 3 As shown, in some embodiments, the sampling bottle 207 and the L-shaped tube 206 are threadedly connected. More specifically, when the staff presses the slide bar 203 to take samples, the water sample is guided to the L-shaped tube 206 through the filter screen 202 and the slide plug 204 in the installation cylinder 201. Since the sampling bottle 207 and the L-shaped tube 206 are threadedly connected, the water sample can flow smoothly into the sampling bottle 207 along the L-shaped tube 206. After sampling, the staff can disassemble the bottle by rotating the sampling bottle 207 in the opposite direction to facilitate the detection of the water sample.

[0036] like Figure 3 As shown, in some embodiments, a rectangular channel 101 is symmetrically constructed on the bottom side of the mounting frame 1, and a slide plate 209 is slidably inserted inside the rectangular channel 101, and the bottom end of the slide bar 203 is connected to the middle of the slide plate 209. More specifically, when the staff presses the slide bar 203 downward, since the bottom end of the slide bar 203 is connected to the middle of the slide plate 209, the slide plate 209 slides down in the rectangular channel 101. The combination of the rectangular channel 101 and the slide plate 209 provides a stable sliding mechanism, ensuring the accuracy and repeatability of the sampling process. This structure avoids the shaking or deviation of the sampler during operation, ensuring the accuracy of the sampling.

[0037] The above description of the disclosed embodiments enables those skilled in the art to implement or use the present invention. Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to the embodiments shown herein, but will conform to the widest scope consistent with the principles and novel features disclosed herein.
