Description of drawings
Fig. 1 is a kind of structural drawing of water-bed bed mud sampling and measuring device.
Embodiment
Below in conjunction with Fig. 1 the present invention is described further, but does not limit the scope of the present invention.
As shown in Figure 1, a kind of water-bed bed mud sampling and measuring device of the present invention comprises that being screwed in leading of empennage connecting pipe 7 tops revolves caudal lobe 10; It is characterized in that empennage connecting pipe 7 ends are connected with the port of following empennage connecting pipe 6 through direct joint 11; Last empennage connecting pipe 7 is hollow structure with following empennage connecting pipe 6 inside, and its inside is provided with connection cord 12, and metal lifts ring 5 and links to each other with an end of the universal abutment ring 8 of the Eight characters through connection cord 12; The other end of the universal abutment ring 8 of the Eight characters links to each other with an end of rope 9; Following empennage connecting pipe 6 bottoms around described metal lifts ring 5 have draining eye 13, and when putting in order to the sampling and measuring device, water is discharged in retaining valve 4 upper tubes; The lower end that metal lifts ring 5 is provided with retaining valve 4; Retaining valve 4 can stop the water in the empennage connecting pipe that the bed mud that the bed mud in the transparent tube 3 washes away and avoid to get is glided, and links to each other with bracing frame 15 through metal connecting tube 14 in the bottom of retaining valve 4, around bracing frame 15, is provided with support bar 2; Transparent tube 3 is arranged in the bracing frame 15; Described transparent tube 3 is tightly connected with metal connecting tube 14, chisel bit 1, and described bracing frame 15 bottoms are connected with chisel bit 1 head thread through thread, and chisel bit 1 bottom is furnished with zigzag drill bit 16.
Described leading revolved 7 one-tenth certain pitch angle splicings of caudal lobe 10 and last empennage connecting pipe; The pitch angle is spent less than 90 greater than zero degree; Angle is different leads that to revolve empennage 10 replaceable through direct joint 11; The leading of different angles revolved caudal lobe 10 can be made bed mud sampling and measuring device be in different rotation rates to fall to boring appearance, leads according to different water depths and bed mud structural adjustment different angles and revolves empennage 10 to reach optimum efficiency.
Described chisel bit 1 is a metal material, and zigzag drill bit 16 usefulness man-made diamonds or alloy material are made.
Described transparent tube 3 is provided with more than 1 or 1, and each transparent tube 3 has the rule of different accuracy and length, and with bed mud thickness at the bottom of the convenient demonstration different water, the material of transparent tube 3 also can be with plastics or organic glass.
Described go up empennage connecting pipe 7, directly joint 11, empennage connecting pipe 6 revolves caudal lobe 10 and is light material and processes with leading down, is partial to the drill bit district to guarantee whole device center of gravity.
Described support bar 2 usefulness metal materials are processed, and with protection transparent tube 3, increase sampling and measuring device bottom weight and fixed support effect.
Described steady arm 2 is provided with more than 3 or 3, its adjustable length.
Described draining eye 13 has more than 1 or 1.
Described chisel bit 1 is provided with more than 1 or 1, and the length of each chisel bit 1 is different, and chisel bit 1 is replaceable through the thread structure.
Described metal connecting tube 14 inwalls, transparent tube 3 inwalls and chisel bit 1 inwall are smooth or are the lubricious material coating.
When using sampling and measuring device of the present invention; With rope 9, hang on the fixed pulley shelf of outer setting earlier, unnecessary rope 9 is wrapped on the up-down shaft clip of outer setting; Then the chisel bit in the sampling and measuring device 1 is aimed at sampling spot; The sampling and measuring device relies on the action of gravity of himself, and free vertical rotation falls to inserting in the bed mud, and hard slightly bed mud in the soft at the middle and upper levels bed mud of water, middle level and bottom hard stratum divide preface to get into drill bit 1 and transparent tube 3; Hard paste or pan soil are bored solid in sawtooth drill bit 16 forward positions; And play the effect that resistance is sealed, because the upwards resistance envelope of retaining valve makes whole bed muds of entering transparent tube 3 can not flow backwards out, realize the sampling of different levels bed mud in the water again; Utilize the up-down shaft clip that the sampling and measuring device is at the uniform velocity fetched the water surface at last, this moment can scale on the transparent tube 3 be measured the degree of depth of bed mud and the bed mud matter of taking out according to the order of sequence in the sampling and measuring device is carried out the analysis of bed mud composition transitivity through observing.
In order to make the water-bed substrate of this sampling and measuring device more effective rotary drill in sampling process; The sampling and measuring device is in manufacturing process; The material that uses is made for the parts on retaining valve 4 all adopt light material, and the parts under the retaining valve 4 all adopt heavy metal material to make.Sampling and measuring device of the present invention, inside communicates when whirlpooling down downwards, and non-return is obstructed when upwards extracting.
More than be preferred implementation of the present invention, all similar changes of doing according to above-mentioned design ought to belong to the content that contains of the present invention.
