Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of sediment sampling, and particularly relates to a new type of simple sediment sampler. Background Technique
[0002] Sediment samplers are indispensable tools in the fields of hydrogeological exploration, environmental monitoring, etc., and are mainly used to collect sediment samples from water bodies such as rivers, lakes, and oceans. Existing sediment samplers are mostly cylindrical or shovel-shaped structures, and they have some limitations in the sampling process. For example, existing samplers usually contain multiple movable parts, which require precise assembly and adjustment, not only increasing the manufacturing difficulty but also raising the failure rate; the operation process is complex and requires professional personnel to operate, increasing the operation cost and time;
[0003] Therefore, it is necessary to design a sediment sampler with a simple structure, convenient operation, and low cost to improve the sampling efficiency, lower the use threshold, and meet the needs of different environments and budgets. Content of the Utility Model
[0004] The purpose of the utility model is to provide a new type of simple sediment sampler to solve the problems of the existing sediment sampler with complex structure, cumbersome operation, and high cost proposed in the above background technique.
[0005] To achieve the above purpose, the utility model provides the following technical solution: A new type of simple sediment sampler, including a sampling main shaft. A circular protruding sleeve slot is provided at the lower end of the sampling main shaft. A circular rubber pad is embedded inside the sleeve slot. The bottom of the sampling outer sleeve is snapped into the sleeve slot. The sampling main shaft and the sleeve slot form a bottom-sealed sampling chamber. A sampling drill bit at a 45-degree angle is installed at the bottom of the sampling main shaft, and a sampling shaft handle is fixed at the top. The sampling shaft handle is fixed inside a handle sleeve. A shim sleeve is provided below the handle sleeve. The locking stud is installed between the longitudinal positions of the shim sleeve and the handle sleeve. A sleeve handle is provided at the top of the sampling outer sleeve.
[0006] Preferably, the sampling outer sleeve is sleeved on the sampling main shaft through its inner diameter adaptability. At the bottom of the sampling outer sleeve, a sleeve slot structure matching the bottom of the sampling main shaft is designed to achieve mechanical interlocking between the two and form the bottom-sealed sampling chamber.
[0007] Preferably, a circular elastic rubber pad is embedded in the sleeve slot, which has certain elastic characteristics to strengthen the sealing performance of the sampling chamber.
[0008] Preferably, the top of the handle sleeve is open, and a bottom plate is reinforced at the bottom.
[0009] Preferably, the sampling shaft handle and the sleeve handle are respectively welded and fixed to the inner surface of the handle sleeve and the outer surface of the sampling outer sleeve.
[0010] Preferably, both the handle sleeve and the shim sleeve are longitudinally arranged along the sampling main shaft, and there is a certain axial interval between them. This interval is precisely designed to fit the locking stud to ensure its positioning at the central position between the two.
[0011] Compared with the prior art, the beneficial effects of the present utility model are as follows:
[0012] 1. The design of this new type of simple sediment sampler allows it to be directly inserted into the sampling pool to collect soil and sediment samples at different radial depths. Due to the synergistic effect of the sampling outer sleeve and the circular rubber pad, a certain amount of water samples can also be effectively collected. In addition, the sampling operation has the least impact on the soil and sediment environment outside the sampling outer sleeve, avoiding disturbing the natural state of the samples and ensuring the representativeness of the samples and the accuracy of the analysis results.
[0013] 2. This new type of simple sediment sampler, with the simplicity of its structural design, significantly reduces the common wear problems of traditional sampling equipment. The optimized design of this sampler reduces the number of moving parts, thereby reducing the part loss caused by friction, and further reducing the maintenance frequency and repair cost. At the same time, the simplified structural design also helps to reduce the material and processing costs during the manufacturing process, making the present utility model have significant advantages in terms of economy.
[0014] 3. The sampling process of this new type of simple sediment sampler is extremely simple. The operator only needs to apply a vertical force through the human body to achieve sampling, without relying on additional complex mechanical driving forces. This design significantly simplifies the sampling operation, reduces the dependence on professional equipment, and improves the sampling efficiency and convenience. Description of the Drawings

[0022] Please refer to Figures 1-4 , the present utility model provides a technical solution: a new type of simple sediment sampler, including a sampling main shaft 1, the lower end of the sampling main shaft 1 has a circular protrusion type sleeve card slot 101, a circular rubber pad 102 is embedded inside the sleeve card slot 101, the bottom of the sampling outer sleeve 2 is clamped into the sleeve card slot 101, the sampling main shaft 1 and the sleeve card slot 101 form a sampling chamber 4 with a sealed bottom, a 45-degree sampling drill bit 103 is installed at the bottom of the sampling main shaft 1, and a sampling shaft handle 104 is fixed at the top, the sampling shaft handle 104 is fixed inside the handle sleeve 105, a filling sleeve 106 is arranged below the handle sleeve 105, the locking stud 3 is installed between the longitudinal positions of the filling sleeve 106 and the handle sleeve 105, and a sleeve handle 201 is arranged at the top of the sampling outer sleeve 2.
[0023] Specifically, the sampling outer sleeve is sleeved on the sampling main shaft through its inner diameter adaptability. At the bottom of the sampling outer sleeve, a sleeve card slot matching the bottom of the sampling main shaft is designed to realize the mechanical interlock between the sampling main shaft and the sampling outer sleeve, forming a sampling chamber with a sealed bottom.
[0024] Specifically, a circular rubber pad is embedded in the sleeve card slot, which not only ensures the sealing of the sampling chamber, but also effectively buffers the contact stress between the sampling main shaft and the sampling outer sleeve through the elastic characteristics of the rubber pad, thereby significantly reducing the friction coefficient, reducing the wear phenomenon, and further prolonging the service life of the equipment.
[0025] Specifically, the top of the handle sleeve is open, and the bottom is reinforced with a bottom plate to increase the overall rigidity and improve the stability and comfort of the sampling operation.
[0026] Specifically, the sampling shaft handle and the sleeve handle are respectively fixed on the inner surface of the handle sleeve and the outer surface of the sampling outer sleeve through the welding process to improve the convenience and stability of the sampling operation process.
[0027] Specifically, both the handle sleeve and the shim sleeve are longitudinally arranged along the sampling main shaft, with a certain axial interval maintained between them. This interval is precisely designed to fit the locking stud, ensuring its positioning between the two, providing stable axial fixation for the sampler and overall structural coordination.
[0028] Working principle: The working principle of this new type of simple sediment sampler is reflected in the sophistication of its structural design and the simplicity of its operation. A 45-degree sampling drill bit is assembled at the lower end of the sampling main shaft. This design optimizes the ability of the drill bit to penetrate the sediment layer, improving the sampling efficiency and the representativeness of the sample. The operator applies vertical pressure through the sampling handle to directly drive the sampling main shaft into the sediment for preliminary sampling. Subsequently, the sampling outer sleeve is inserted into the sleeve slot of the sampling main shaft, and the groove matching technology is used to ensure a tight connection between the two, forming a bottom-sealed sampling chamber, thereby effectively isolating external pollutants during the sampling process and ensuring the purity of the sample. Further, the vertical position matching of the shim sleeve and the handle sleeve is fixed through the locking stud, ensuring the overall assembly and stability of the three major components: the sampling main shaft, the sampling outer sleeve, and the locking stud. This structure not only simplifies the assembly process but also enhances the stability and reliability of the sampler during operation. After sampling, the operator can easily lift the sampler.
[0029] Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
