Description
Technical field
The present invention relates to a kind of sediment sampler, especially a kind of driving formula throws type self-stabilization sediment sampler.
Background technology
The extensive research of the problems such as with to rivers and lakes sediment siltation, sediment pollution and eutrophication, silt sampling cartridge
The demand set is increasing.In the case of the depth of water is little（Less than 1 meter）, generally can using traditional hand sampling device
To meet the requirements, but in the case of the depth of water is bigger（1 meter or more）, can not just use manually sampling apparatus.Acquisition
The silt sample of river or lake-bottom has following requirement：1. sampling operation is the smaller the better to the disturbance of bed mud；2. needing
Progress vertically takes sample, to analyze the delamination of silt；3. equipment requirement flexibility is strong, different positions can be flexibly taken
The silt sample set；4. taking the cost of sample low, labor intensity is low etc..
It is other that existing silt sampler can mainly be summarized as three categories：Sampler is tunneled manually, throws formula sampler
With fixed driving sampler.Driving sampler is flexibly light manually, and sampling is at low cost, but can not adapt to deep water sampling；It throws
Formula sampler maneuverability is set, is suitable for deep water sampling, but traditional at present throw formula sample thief and can only take bed mud surface layer
Sample, and have prodigious disturbance to sample layer；Fixed driving sampling needs that the anchoring pedestal in river bed is arranged in lower end
Upper installation sampler, the fixed driving sampler realize taking for silt sample by stabilising arrangement and control device, in this way may be used
The shortcomings that overcome first two sampling apparatus, but the expensive of pedestal is anchored, and can not move, flexibility is poor；It is above-mentioned
The other sediment sampler of three categories all there are respective advantage and disadvantage.
The present invention addresses the above problem, provide it is a kind of to sample level disturb it is small, use cost is low, flexibility is good, labor
Fatigue resistance is low, it is easy to use, can be achieved voluntarily to stablize that vertically the driving formula of deep water sample to be taken to throw type voluntarily steady by throwing
Determine sediment sampler.
To achieve the above object, the present invention adopts the following technical scheme that：The present invention includes that stabilized driving system and driving are adopted
Sample system, structural feature be stabilized driving system include stabilizer, it is setting driving impeller in stabilizer, universal plate, universal
Ring, fixed frame, connection ring, be respectively set inside fixed frame motor, battery and the electric machine support being sequentially connected, flexural pivot, swing arm,
Weight is provided with the positioning disk of location hole among fixed frame, and swing arm is passed through out of location hole, and driving impeller is connected to the motor,
Universal plate is rotatablely connected with fixed frame by cardo ring；Driving sampling system includes sampling cylinder, driving ring and from purl, sampling cylinder
Upper and lower ends are connected with connection ring, driving cutting ring respectively, and annular spread is fixed on sampling cylinder and driving cutting ring from purl outer end
Between.
Invention advantageous effect
The present invention using stabilized driving system the structures such as stabilizer, universal plate and weight, can effective control action,
Ensure the posture sunk with tunneling process holding vertically downward；Motor, driving impeller drive driving cutting ring downlink, realize underwater row
Into and sampling；It tunnels sampling system to be provided with from purl on the inside of driving cutting ring, is effectively prevented sample landing；Structure of the invention
Simply, compared with existing underwater fixed sampling apparatus, equipment price is cheap, and sampling cost is lower；There is manual pick simultaneously
The advantages of very little is disturbed to sample level into sampler；It can also use and throw mode into, in the effect realization pair of stabilized driving system
Automatic sampling in profundal zone, shallow water area can directly manual operations take sample, have the absolute predominance of maneuverability.

Specific implementation mode
The present invention includes stabilized driving system 6 and driving sampling system 8, and stabilized driving system 6 includes stabilizer 9, stablizes
Setting driving impeller 11, universal plate 1, cardo ring 20, fixed frame 3, connection ring 7 in the wing 9, be not arranged inside fixed frame 3 motor 12,
Battery 13 and electric machine support 2, flexural pivot 14, swing arm 15 and the weight 16 being sequentially connected are provided with location hole 5 among fixed frame 3
Positioning disk 4, swing arm 15 is passed through out of location hole 5 and the upper end and flexural pivot 14 are hinged；Drive impeller 11 and 12 phase of motor
Even, it is evenly distributed with four pin holes on cardo ring 20, two centrosymmetric pin uranium I are respectively set on universal plate 1 and fixed frame 3（21）、
Sell uranium II（22）, sell uranium I（21）, pin uranium II（22）Coordinate with the pin hole on cardo ring 20, cardo ring 20 can be around pin with universal plate 1
Uranium I（21）It relatively rotates, cardo ring 20 can be around pin uranium II with fixed frame 3（22）It relatively rotates, that is, realizes universal plate 1 and fix
The rotation connection of frame 3 in both directions；It includes sampling cylinder 17, driving cutting ring 19 and from purl 18, sampling cylinder to tunnel sampling system 8
17 upper and lower ends respectively with connection ring 7, driving cutting ring 19 be connected, annular spread from 18 outer end of purl be fixed on sampling cylinder 17 and
It tunnels between cutting ring 19.
It installs from 19 inside of driving cutting ring of purl 18 and is additionally provided with annular table 23；Improve the machine for preventing sample from sliding
Rate.
Setting can install lifting rope hole 10 or tied rope column etc. on stabilizer 9.
Sampling cylinder 17 can be coordinated or using modes such as quick change card slots with connection ring 7, driving cutting ring 19 by screw thread, slight interference
Flexible connection can match the sampling cylinder 17 for being suitble to length according to the requirement of sampling depth.
When work, the sampling cylinder 17 of suitable length is first chosen, and combine with driving cutting ring 19 and connection ring 7, reconnected suitable
When the rope of length, the present invention is thrown into water, motor 12 starts at this time, and driving impeller 11 rotates, in the effect of stabilizer 9
Under, the posture that the present invention keeps driving cutting ring 19 downward is moved to the bottom, under the rotary thrust effect of driving impeller 11, this hair
The bright opposite direction that can be rotated with driving impeller 11 while moving downward rotates, and when driving cutting ring 19 contacts the bottom, opens
Begin to tunnel sampling, be rotated upward from the tip portion stress of purl 18, sample enters sampling cylinder 17；During this period if this hair
Bright posture and deviation occurs vertically downward, weight 16 drives universal plate 1, cardo ring 20 to rotate by gravity, realizes to this
The traveling posture of invention is corrected, and when connection ring 7 touches the bottom, is completed sampling, rope is lifted upwards, at this time from purl
Under 18 tip portion resets, and the annular table 23 on driving cutting ring acts on, sample is effectively prevent to slide downwards.
