Description
Technical field
The utility model relates to a kind of sandy riverbed bed material sampling thief, specifically is a kind of sandy riverbed of cartridge type bed material sampling thief that drags.
Background technology
Bed material sampler is an instrument of gathering silt sample in bed surface or the following certain depth of bed surface.At present, the sandy riverbed of known traction load its pattern of bed material sampling thief has pull-type (as drag husky tube etc.), digging type (as bucket formula sampling thief etc.) and brill formula (as the piston type sampling thief etc.) three classes, be mainly used in gather particle diameter at the gravel below 10 millimeters and slightly, the fine sand sample.1. dragging husky tube is to be made of with the tow strap that lies on the tube a cylinder with sharp-edged.The end of tube is equipped with and can unloads the Sheng sample bottle of getting, and makes the flat river bed of crouching of cylinder, the towing sampling.Has heavy ball on the tow strap, in order to improve the sampling effect.2. bucket formula sampling thief partly is made up of bucket, the claw that limits the bucket position and fish lead housing etc.When sampling thief is transferred to the river bed, be positioned at the contact lever lifting of fish lead bottom, the spacing claw of bucket is unclamped, receive the strand hoisting rope subsequently, borrow the instrument deadweight to drive bucket upset sampling.3. the piston type sampling thief is pressed into the riverbed with cylinder (pipe) during sampling, along with sample enters in the pipe, the pipe inner carrier is risen, and borrows piston to move formed partial vacuum, can make sample maintain an interior unlikely leakage.Existing sandy riverbed bed material sampling thief complex structure is subject to the grit particle size and simultaneously because of the flow rate effect sample collecting accuracy rate of current.
The utility model content
The utility model provide a kind of light simple and easy, the degree of accuracy that is easy to carry and takes a sample is higher drags the sandy riverbed of cartridge type bed material sampling thief.
The technical solution of the utility model is as follows:
Drag the sandy riverbed of cartridge type bed material sampling thief, comprise the sampling cylinder, sampling is provided with a demarcation strip in the cylinder vertically, demarcation strip will take a sample cylinder be divided into about two parts; The one end sealing of sampling cylinder; The other end is the sampling end, and its end face is the inclined-plane; The sampling end is provided with a baffle plate, and the lower limb of baffle plate links to each other with demarcation strip, and closes the upper part of sampling end; The lower part of sampling end is a sample tap, and the top of sampling cylinder is provided with water delivering orifice near the baffle plate place; At the blind end of sampling cylinder, two parts up and down of sampling cylinder are communicated with; Be provided with the straw line stationary installation in the sampling cylinder outside.Utilize the river water flow pressure to push down baffle plate, " ㄈ " type structure and can slow down water flow velocity in the sampling cylinder, overcome silt and wash in a pan Lou because of flow rate of water flow is too anxious.
Further, the end face of sampling end becomes miter angle with demarcation strip.
Further, the ratio of the area of two parts is 1: 2 about the xsect of sampling cylinder.
Further, be provided with filter net sheet in the sampling cylinder, filter net sheet links to each other with the blind end of demarcation strip with the sampling cylinder respectively.The method to set up of filter net sheet can have a variety of, and such as also being provided with like this: demarcation strip links to each other with the blind end of sampling cylinder; At the blind end near the sampling cylinder, demarcation strip is provided with filter net sheet.Filter net sheet passes through current and the grains of sand can not pass through, thereby guarantees not leak sand.
Further, according to different request for utilizations, the different degree of depth and water velocity may need to add counterweight and just can make sampling thief be sunken to the riverbed, for this reason, are provided with the counterweight stationary installation in the outside of sampling cylinder.The counterweight stationary installation can be various, and a kind of easy method is exactly the sheet metal that is fixed with through hole on the sampling cylinder, as required counterweight is fixed in the requirement that can satisfy additional bob-weight on the sheet metal.Also can be directly in the outside fixed weight of cylinder of taking a sample.
The utility model adopts " ㄈ " type structure can slow down water flow velocity in the sampling cylinder, overcomes silt and washes in a pan Lou because of flow rate of water flow is too anxious.The utility model light simple and easy, the degree of accuracy that is easy to carry and takes a sample is higher, has promotional value.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the structural representation of the utility model embodiment 1.
Embodiment
As shown in Figure 1, the utility model drags the sandy riverbed of cartridge type bed material sampling thief, comprises sampling cylinder 1, and sampling is provided with a demarcation strip 2 in the cylinder vertically, demarcation strip 2 will take a sample cylinder 1 be divided into about two parts; The one end sealing of sampling cylinder 1, the left side as shown in Figure 1; The other end is the sampling end, and its end face is the inclined-plane, the right as shown in Figure 1; The sampling end is provided with a baffle plate 5, and the lower limb of baffle plate 5 links to each other with demarcation strip 2, and closes the upper part of sampling end; The lower part of sampling end is a sample tap 4, and the top of sampling cylinder 1 is provided with water delivering orifice 6 near the baffle plate place; Blind end 3 at sampling cylinder 1 is provided with intercommunicating pore 7, thereby two parts up and down of sampling cylinder are communicated with; Be provided with straw line stationary installation 8 in sampling cylinder 1 outside.
Below the utility model is described in further detail.
As shown in Figure 2, sampling cylinder 1 is that a thickness is 2.0mm, bore 15cm, and the stainless steel cylinder of long 45cm, its left side sealing is blind end 3; Demarcation strip 2 in the sampling cylinder 1 is a corrosion resistant plate, the sealing cross septation be 1/3 volume prolong cause tin at the bottom of, from the xsect of sampling cylinder 1, the ratio of the area of two parts is 1: 2 up and down.Demarcation strip 2 and blind end 3 junctions promptly are welded with filter net sheet on the intercommunicating pore 7, and this filter net sheet is 20 order stainless (steel) wire sieving water sheets.The sampling end-grain cutting of sampling cylinder 1 becomes 45 degree inclined-planes.1/3 by 5 sealings of a slice baffle plate on the nozzle, and baffle plate 5 adopts corrosion resistant plate, and the top of sampling cylinder 1 is provided with water delivering orifice 6 near the baffle plate place, and both sides are welded leads counterweight 9 in addition before and after the sampling cylinder, are 5kg thereby make general assembly (TW), and straw line is fixed on the straw line stationary installation 8.
The utility model bed material under straw line pulling enters from sample tap 4 and makes that water can upwards slow down flow velocity with " ㄈ " type and slowly discharge along its mesh screen hole in the tube, overcoming silt washes in a pan Lou because of flow rate of water flow is too anxious, tube prodelta clay water when also having overcome sampling simultaneously, guarantee the accuracy of collected specimens, it is representative preferably to guarantee that sample has.The sandy riverbed of the utility model bed material sampling thief is based on the sampling thief deadweight, adds to utilize the downward pressure that baffle plate produced of flow power to miter angle inclined-plane additional on the sampling thief, makes sampling thief gather bed material under bed surface under natural pressure.
