Technical field

The invention belongs to Ecology monitoring device technical field more particularly to a kind of visualization zoobenthos acquisition devices.

Technical background

Zoobenthos refers to that the wholly or largely time of the history of life moves in the biology of water bottom, is ecology of water The important composition biological group of system, most of zoobenthos have regional strong, migration energy due to living in bed mud for a long time The features such as power is weak, life phase are usually poor for the avoidance ability of environmental pollution and variation and react environmental change to stabilization Sensitivity, type, quantity and structure of community can change with the variation of water quality, utilize the population structure of zoobenthos, sociales The parameters such as class, quantity can objective, accurately reflect the pollution situation of the water quality of its living environment, be the finger for evaluating water body environment The property shown biology.Present zoobenthos has widely been moved the research of the various water environment pollution situations such as Yu Haiyang, river.

Bottom sampler common at present includes grab bucket-type dredger and box bottom sampler, such as patent document (CN109163934A) grab bucket-type dredger disclosed in.Grab bucket-type dredger is mainly made of symmetrical two-part arc grab bucket Sampling grab bucket, machine driving executing agency composition, pass through pull machine driving actuating mechanism controls sampling grab bucket carry out mud Crawl, then firmly lifting sampling grab bucket, sampling grab bucket will be in river bed sludge sampling grab bucket by gravity block closure.On but The grab bucket-type dredger stated, has the following problems in actual use: these bottom samplers utilize gravity after reaching the bottom It realizes grab bucket closure, but is easy to be stuck in water-bed, irretrievable problem in the presence of grab bucket, bottom sampler loss is big, and may indulge in Accidentally sampling operation causes more manpower and material resources to lose.

Summary of the invention

To overcome above-mentioned the deficiencies in the prior art, the purpose of the present invention is to provide a kind of acquisitions of visualization zoobenthos to fill It sets, camera lens is set inside bottom sampler, by optical fiber by water-bed image transmitting to waterborne, before being sampled, operator is logical Eyepiece or image display device observation water bottom landform are crossed, for being not suitable for the region of sampling, bottom sampler is withdrawn, is reset Sampling position avoids bottom sampler and is easy to be stuck in water-bed, irretrievable problem, effectively increases the recycling of sampling bottom sampler Rate, and avoid more manpower and material resources losses.

To achieve the above object, the technical solution adopted by the present invention is that: a kind of visualization zoobenthos acquisition device, including The grab bucket of left and right two, two grab buckets are connected by shaft；The back side rear end of two grab buckets respectively connects a lifting rod, two lifting rods Upper end be respectively connected with a retaining ring, by retaining ring be directly connected to rope tool；Two grab buckets are left grab bucket and right grab bucket respectively；Left grab bucket The back side be provided with a support rod；The back side of right grab bucket is provided with the card slot of a strip, card slot upper end closed；Support rod can be It is slided in card slot；Left grab bucket is equipped with beam projecting device；Right grab bucket is equipped with light collection device.
