Embodiment
Presently preferred embodiments of the present invention is described in detail below in conjunction with the accompanying drawings, so that advantages and features of the invention energy It is easier to be readily appreciated by one skilled in the art, apparent is clearly defined so as to be made to protection scope of the present invention.
Refering to accompanying drawing, a kind of mud sectional sampling device, including：Collection tube 1, handle 2, keeper 3, turnover panel 4, limited block 5 and nonwoven layer 6.
Handle 2 is connected to the top of collection tube 1, and its role is to be easy to firmly push during hand-held sampling and above carry.Handle 2 On be provided with external screw thread, external screw thread can be positioned only at one end of handle 2, the both ends of handle 2 can also be arranged on, for external Sleeve pipe.
Collection tube 1 is columnar hollow structure, constitutes the main body framework of sampler.The upper end closed and handle of collection tube 1 Hand 2 is connected, and the lower end of collection tube 1 is set for opening.The lower end of collection tube 1 is provided with sharp portion, and sharp portion includes a sharp head, Sharp head can be located at the centre of the bottom of collection tube 1, i.e. sharp portion is inverted cone shape；Sharp head may be alternatively located at the one of the bottom of collection tube 1 Side, i.e. sharp portion are in side inclined plane shape.
In order to avoid due to turnover panel 4 and collection tube 1 it is closed not tight, cause mud from gap leakage, in the sharp of collection tube 1 Portion is provided with the rubbery loop 7 of ring-type, covers rubbery loop 7 again after the fixation of keeper 3, avoids mud sample 9 from gap Seepage.
Keeper 3 is plugged in collection tube 1 by the positioning hole on collection tube 1, and one end of keeper 3 sets collection tube 1 Outside, fixed turnover panel 4 is played a part of.Keeper 3 can be common latch, or be shaped as T-shaped keeper 3.Extract During keeper 3, turnover panel 4 can turn over downwards, and the mud sample 9 of collection can drop out collection tube 1.For preferably fixed positioning piece 3, One projection can be set the opposite face of positioning hole in collection tube 1 so that one end that keeper 3 is located in collection tube 1 can be put Put on projection.
Turnover panel 4, it is hinged on the inwall of collection tube 1, and its articulated manner can be common closing structure.The shape of turnover panel 4 Shape and size are adapted with the inwall of collection tube 1, and the inwall of turnover panel 4 and collection tube 1 is in close contact.After keeper 3 is inserted, turn over Plate 4 is arranged on the top of keeper 3, and keeper 3 is located on the center line of turnover panel 4, can preferably support turnover panel 4.Push collection tube 1 When, turnover panel 4 can only be unidirectionally flipped up, and collection sample 9 is entered sampler；When above carrying collection tube 1, turnover panel 4 is adopted The Action of Gravity Field of collection sample 9 will fall after rise downwards, and final turnover panel 4 plays the work of the closing sampler space under the barrier of keeper 3 With.
Turnover panel 4 is identical with the quantity of keeper 3.According to the quantity of required sampling, the corresponding quantity of turnover panel 4 can be set. Preferable in the present invention, the quantity of keeper 3 is at least two.
Limited block 5 is arranged on the inwall of collection tube 1, and it can be arbitrary convex shape, ensures that turnover panel 4 will not be with collection The tube walls parallel of pipe 1, avoiding turnover panel 4 from being disposed vertically can not fall after rise to keeper 3.Limited block 5 is be hinged with collection tube 1 to turnover panel 4 The distance at place is less than the length of turnover panel 4, and preferable in of the invention, limited block 5 to turnover panel 4 and the distance of the hinged place of collection tube 1 are The 1/2~2/3 of the length of turnover panel 4.
Nonwoven layer 6 is pasted with the inwall of collection tube 1 so that the water inside sampler passes through nonwoven layer 6, can be from The osculum of the upper end of collection tube 1 is finally discharged, and nonwoven cloth material and can enough avoids mud sample 9 from appearing, permeable so as to reach The purpose of impermeable mud sample 9.Sample leakage or Sample Dilution are effectively avoided in sampling process, sampling precision is high, so as to effectively Ensure the accuracy rate that sample 9 is tested.
The upper end of collection tube 1 is provided with delivery port 8, and it is uniformly arranged in the side wall of collection tube 1.Delivery port 8 is simultaneously Ventilative effect is served, the internal pressure of collection tube 1 can be balanced, discharges unnecessary air and water.
A kind of mud sectional sampling method, is comprised the following steps that：
1st, the rubbery loop 7 on the sharp portion set of collection tube 1, avoids sampler mud sample 9 during extraction The seepage from gap.
2nd, according to the position where required sampling mud, judge whether to need the external sleeve pipe on the handle 2 of sampler, If sampling ground is sampled close to bank or by ship, need not external sleeve pipe；External sleeve pipe is such as needed, external sleeve pipe need to be considered Length, sampler and sleeve pipe are fixed by the screw thread on handle 2.
3rd, among sampler being inserted perpendicularly into mud at sample point, due to the resistance by water body or mud, turnover panel 4 It can dig upwards, water or mud will enter sampler, and with the lasting insertion of sampler, multiple turnover panels 4 are from bottom to top It is flipped up successively, the water or mud of deeper inside continue into sampler.
It should be noted that the length of sampler according to the depth and quantity of sampling quantity of collection mud, need to be determined and needed The space of several collection samples 9 is wanted, is also just correspondingly arranged several turnover panels 4, keeper 3 and limited block 5.
4th, after sampler test depth reaches collection requirement, sampler is vertically extracted, is vertically extracting this process In, it will downwards be fallen after rise by the turnover panel 4 of the collection Action of Gravity Field of sample 9, finally under the barrier of keeper 3, form taking for closing Sample space, form the sampling region of multiple segmentations.Water in sampler will flow through nonwoven layer 6, be discharged from collection tube 1.
5th, after sampling terminates, keeper 3 is pulled up successively from bottom to top, turnover panel 4 is downwardly turned over by the effect of mud gravity, Mud sample 9 is fallen into collection vessel from sampler.Mud sample 91, mud sample 92 are arrived into mud sample 9N successively During collection vessel is interior corresponding to being put into, in order to ensure mud sample 9, a upper mud sample 9 is not residual in by collection tube 1 The pollution of thing is stayed, opens the keeper 3 of last layer again after collection tube 1 is cleaned.
Embodiments of the invention are these are only, are not intended to limit the scope of the invention, it is every to be said using the present invention The equivalent structure or equivalent flow conversion that bright book and accompanying drawing content are made, or directly or indirectly it is used in other related technology necks Domain, it is included within the scope of the present invention.
