Abstract
The invention discloses a valve sampler for taking a continuous undisturbed sediment sample by drilling, which comprises a driving hammer, a slide bar, a bearing platform, a pvc sampling pipe, a fixed bracket, a stainless steel sampling head, a valve and other members. The driving hammer falls freely along the slide bar to strike the bearing platform to allow the sampler to drill into a sediment layer. The underpart of the bearing platform is formed by serially connecting the fixed bracket and the stainless sampling head. The fixed bracket is formed by welding upper and lower tension sleeves and three hollow support bars, and the pvc sampling pipe is inserted into the fixed bracket from the lower end of the fixed bracket and is fixed. The stainless sampling head is provided with a valve device, and the valve is level with the wall of the pipe when opening and can cut the sediment here and block the sample in the sampling pipe when closing. Before sample extraction, air is compressed into the bottom end of the sampling head to eliminate bottom negative pressure generated due to the up-pull of the sampler. The sampler can extract an over 2 meter cylindrical sediment sample at one time and store the 2 meter cylindrical sediment sample in the pvc pipe above, so the sample does not contact water and is polluted or diluted, and the long cylindrical sample is usually easy to be cut into small segments for storage after being extracted.
Description
Technical field
The present invention relates to river course, bottom mud in lake mud sampler, especially relate to a kind of valve sampler that is used for taking continuous undisturbed sediment sample by drilling.
Background technology
Become the presence of pollution sources of water body after in a single day river course, bottom mud in lake are polluted, the The Long-term Effect water body environment.In order to study pollutants transfer, conversion and accumulation between water body and the bed mud, and to the influence of water body environment, must be from drilling through different depth original state bed mud sample under water, be used to test wherein pollutant load and with the depth profile section.Domestic and international existing bed mud sampling equipment mainly comprises grab simpler and geological drilling rig at present.Grab simpler is simple in structure, and is easy to operate, but its sampling depth is limited, big in the extracting process to the sample disturbance, and because its sealing difference easily causes sample to run off, and in the sample extraction process, contact with water body and be vulnerable to pollute or dilution, be difficult to satisfy high precision measurement and study requirement.Utilize geological drilling rig to take a sample in the waters and need set up a carrying platform or adopt special boat-carrying rig, equipment is big, and the sampling expense is than higher and heavy, and in addition, existing geological drilling rig is equipped with the routine sampling device or stopple coupon is difficult to once obtain undisturbed sample more than 1 meter.Above-mentioned deficiency makes them be difficult to satisfy the high precision research requirement of this technical field.
Summary of the invention
The object of the present invention is to provide a kind of valve sampler that is used for taking continuous undisturbed sediment sample by drilling.
The technical solution used in the present invention is:
The present invention includes the hammer, slide bar, cushion cap, pvc sampling pipe, fixed support, valve and the stainless steel sampling head that have suspension ring.In the center pit of hammer slide bar is housed, the center pit of slide bar upper end and hammer is for being slidingly matched, the slide bar lower end is welded on the cushion cap, boss below the cushion cap is with cranse outward and locks with bolt, last cranse and following cranse outside evenly are welded with hollow support rails and form fixed support, last cranse and following cranse internal fixation have the pvc sampling pipe, sampling head is welded on down the cranse bottom, the section of jurisdiction is downcut by vertical projecting line at sampling head tube wall upper edge internal diameter circle, after loading onto rotating shaft, the two ends of section of jurisdiction length direction make valve, operating rod is equipped with in last cranse side, after one end of operating rod and control pull bar is hinged, the other end of control pull bar passes near the hollow support rails and the valve lower end of valve side hinged, pass near hinged after the hollow support rails of valve side with the valve lower end, operating rod is cocked, valve is with sampling thief bottom complete closed, operating rod is depressed, valve just flushes with tube wall, the sampling thief bottom is open fully, on the sampling head tube wall below the valve, be drilled with air hole, air hole is communicated with another root hollow support rails lower end, and its upper end has air admission hole, and air admission hole is connected with inflator with flexible pipe.
The beneficial effect that the present invention has is:
1) makes valve on the stainless steel sampling head, flush with tube wall when valve is opened, just the sampling thief bottom is sealed when closing.Valve opens and closes by coupled pull bar and realizes.
2) the hollow support rails lower end extends under the valve, and the upper end connects a simple and easy inflator with flexible pipe, can eliminate the bottom negative pressure that is produced because of pulling out on the sampler by this hollow support rails gas injection, and it is more easy that sampler is extracted, and avoid sample by disturbance.
3) the present invention uses hammer bump cushion cap, is passed to the stainless steel sampling head through fixed support, and it is pierced under water in the bed mud, and the disposable degree of depth of creeping into bed mud can be above 2 meters.
4) this sampler can disposable extraction column sediment sample more than 2 meters, seal pipe up for safekeeping at leaching process column sediment sample at pvc, maintain the original state, can contact and contaminated or dilute with water body.
5) select the sleeve of inertia pvc material pipe for use, can not cause bed mud to be subjected to secondary pollution, easily intercept into segment after elongated column sample extracts and deposit as sediment sample.
