Description

Technical Field

[0001] The utility model relates to the technical field of water conservancy projects, in particular to a multi-layer water sample drilling type sampler. Background Art

[0002] When constructing the foundation of a water conservancy project, it is usually necessary to first sample and test the geographical environment. A borehole sampler is a device for drilling and sampling the geological environment. When sampling the mud layer, a conventional borehole sampler can only sample a single layer of mud, which requires repeated sampling during the sampling process, which can easily cause different layers of mud to cross-layer, thereby affecting the sampling and testing of the mud.

[0003] A drilling sampler with the public specification of the utility model patent application in China as CN219391427U, although the mud moves upward and flows out from the sampling port of the shell, so that the mud can be collected after sampling, it is difficult to easily insert the device sampler into the soil during use, and it is impossible to know the sampling depth of the sampler. Therefore, a multi-layer water sample drilling sampler is proposed. Utility Model Content

[0011] Preferably, the top end of the rotating rod passes through the sampler and extends to the outside of the mounting frame, and a handle is fixedly provided on the top end of the rotating rod.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] By turning the handle, the threaded rod is driven to rotate. At this time, under the action of the measuring rod, the movable plate can play a role of limiting and guiding, so that the movable plate can move vertically up and down along the surface of the threaded rod, thereby driving the sampler to move accordingly, and under the action of the drill bit, the sampler can be easily inserted into the soil.

[0014] By turning the handle, the rotating rod is driven to rotate, and the sealing gasket and the baffle can be driven to rotate inside the sampling slot. When the sealing gasket blocks the sampling port, it can effectively prevent excess impurities from entering the sampling slot. At the same time, when the baffle blocks the discharge port, it can effectively prevent the water sample inside the sampling slot from being discharged. When the sealing gasket blocks the sampling port, the discharge port will not be blocked. Conversely, when the baffle blocks the discharge port, the sampling port is opened. This setting is convenient for the staff to operate and use. It is simple to operate, convenient for the staff to use, and improves the overall use effect of the equipment.

Moreover, this setting is more labor-saving than manually rotating the drill bit 6, thereby improving the working effect.

[0026] In this embodiment, preferably, the top end of the threaded rod 3 extends to the outside of the installation frame 1 and is provided with a handle 7;

[0027] Through the above scheme, the rotation speed of the threaded rod 3 can be controlled to achieve the displacement distance control of the moving plate 4, thereby driving the sampler 5 to move accordingly;

[0029] Through the above scheme, the measuring rod 8 can play a role of limiting and guiding the movable plate 4, so that the movable plate 4 can move vertically along the surface of the threaded rod 3. At the same time, the surface of the measuring rod 8 is provided with a scale, which is convenient for the staff to observe it, and it is convenient to know the depth position of the sampler 5 sampling, and it is also convenient for the staff to use it;

[0030] In this embodiment, preferably, the sampling mechanism includes a sampling slot 9, a partition plate 10, a rotating rod 11, a sealing ring 12, a support rod 13, a sealing gasket 14, a baffle 15, a sampling port 16 and a discharge port 17.
