Description

Technical Field

[0001] This utility model relates to the field of water quality sampling technology, specifically to an efficient water and soil sample collection device. Background Technology

[0002] Water sampling is a crucial step in environmental monitoring. It requires scientific planning of sampling sites, the use of clean and suitable containers and professional equipment, and the collection of surface or deep water samples according to standards. Specific sampling and preservation measures should be taken for special items (such as heavy metals and organic matter). At the same time, sampling information should be strictly recorded to avoid contamination and aeration, ensure the integrity and representativeness of the samples, and use blank samples, parallel samples, and quality control samples to ensure quality and provide a reliable basis for subsequent water quality analysis.

[0003] According to the semi-automatic water sampler published on the China Patent Network with publication number CN214621822U, it includes a cup body. A water outlet pipe is fixedly connected to one side of the cup body. A sleeve is movably connected to the outer wall of the water outlet pipe. A sealing gasket is fixedly connected to the inner wall of the sleeve. A baffle is fixedly connected to the inner side wall of the cup body. A fixed frame is movably connected to the top of the baffle. A filter screen is fixedly connected to the inner wall of the fixed frame. A fixed block is fixedly connected to one side of the cup body. A handle is movably connected to one side of the fixed block. A rotating block is fixedly connected to one end of the handle. This semi-automatic water sampler achieves the goal of easy installation, facilitating installation and use, meeting people's work needs, greatly improving the sampler's working efficiency, reducing work pressure, and bringing convenience to people's work. It is worthy of promotion and use. However, the water sampler has poor sampling effect. It is difficult to perform stratified sampling during sampling, and can only sample a fixed water layer. The sampling effect is relatively simple, requiring multiple samplings to achieve the sampling target.

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] like Figures 1 to 4 As shown, the present invention provides an efficient soil and water sample collection device, which includes a sampling bucket 1, a layered sampling component 2 and an isolation component 3;

[0027] The layered sampling assembly 2 includes a rotating cover 201, which is movably connected to the sampling bucket 1. A pull rope 202 is fixedly connected to the top of the rotating cover 201. A support plate 203 is fixedly connected to the top of the sampling bucket 1. A guide frame 204 is fixedly connected inside the support plate 203. A guide wheel 205 is movably connected inside the guide frame 204. The pull rope 202 passes through the guide frame 204 and is movably connected to the guide wheel 205. A handle 206 is fixedly connected to the surface of the sampling bucket 1. A traction rope 207 is fixedly connected to the surface of the handle 206. The traction rope 207 is located at the top of the sampling bucket 1. A sealing ring 208 is fixedly connected to the bottom of the rotating cover 201. A magnet 209 is fixedly connected to the top of the sampling bucket 1. The top of the magnet 209 is attracted to the bottom of the rotating cover 201.

[0028] refer to Figure 4 The isolation component 3 includes a guide plate 301, which is fixedly connected to the inner wall of the sampling barrel 1. A suspended isolation block 302 is provided inside the sampling barrel 1. The suspended isolation block 302 is located at the bottom of the guide plate 301. A short block 303 is fixedly connected to the surface of the suspended isolation block 302. An isolation rope 304 is fixedly connected to the top of the short block 303. The top of the isolation rope 304 extends through to the top of the sampling barrel 1.

[0029] As a technical optimization of this utility model, by setting an isolation component 3 to isolate the water sample inside the sampling bucket 1, two water layers can be sampled at the same time, which improves the sampling effect of the sampling bucket 1.

[0030] refer to Figure 4 A fixed frame 4 is fixedly connected to the bottom of the sampling bucket 1, and a counterweight 5 is set inside the fixed frame 4.

[0031] As a technical optimization of this utility model, by setting a fixed frame 4 and a counterweight block 5, the counterweight of the sampling bucket 1 can be increased, making the sampling bucket 1 sink more quickly and improving the ease of use of the sampling bucket 1.

[0032] refer to Figure 4 A magnet plate 6 is fixedly connected to the rear side of the inner wall of the fixed frame 4, and the front side of the magnet plate 6 is attracted to the rear side of the counterweight 5.

[0033] As a technical optimization of this utility model, by setting the magnet plate 6, the counterweight 5 can be fixed, preventing the counterweight 5 from falling off the fixing frame 4, thereby improving the stability of the counterweight 5.

[0034] refer to Figure 4 A handle 7 is fixedly connected to the front side of the counterweight 5, and the surface of the handle 7 is provided with anti-slip texture.

[0035] As a technical optimization of this utility model, by setting a handle 7, it is easier for users to pull the counterweight 5, thus improving the ease of use of the counterweight 5.

[0036] refer to Figure 4 A positioning block 8 is fixedly connected to the surface of the suspended isolation block 302, and a positioning rod 9 is fixedly connected inside the sampling barrel 1. The positioning rod 9 is movably connected to the positioning block 8.

[0037] As a technical optimization of this utility model, by setting the positioning block 8 and the positioning rod 9, the suspended isolation block 302 can be limited, thereby improving the movement stability of the suspended isolation block 302.

[0038] The working principle and usage process of this utility model are as follows: When conducting water quality sampling, the sampling bucket 1 needs to be placed in the water. At this time, the counterweight 5 accelerates its descent by its own weight, causing the sampling bucket 1 to quickly reach the target depth. After the sampling bucket 1 sinks to the specific water layer to be sampled, the operator pulls the pull rope 202 upwards. Under the traction of the pull rope 202, the rotating cover 201 rotates upwards along a predetermined trajectory to open. During this process, the guide frame 204 and the guide wheel 205 work together to provide limit and support for the pull rope 202, ensuring its stable operation. At this time, the water flows smoothly into the sampling bucket 1. After completing the sampling of this water layer, the operator releases the cover. Pulling rope 202 in turn pulls the isolation rope 304 upwards. The rotating cover 201 closes quickly under the attraction of the magnet 209, achieving the initial sealing of the sampling bucket 1. At the same time, the isolation rope 304 drives the suspended isolation block 302 upwards through the short block 303. The suspended isolation block 302, with the help of the guide plate 301, effectively seals the water in the sampling bucket 1, preventing water samples from different layers from mixing. Through the above operation, sampling of one water layer can be easily completed. Afterwards, the same steps can be repeated to sample other water layers in sequence, thereby achieving the purpose of stratified sampling and providing accurate, stratified water sample data for subsequent water quality analysis.

[0039] In summary, this efficient water and soil sample collection device utilizes a stratified sampling component for stratified sampling. During sampling, it can perform stratified sampling, enabling sampling of different water layers. The sampling results are more diverse, and the sampling target can be achieved without multiple samplings, thus solving the problem of difficult stratified sampling.
