Abstract
The utility model relates to an on - -spot simple and easy benthos elutriator, including cylindric body, characterized by: the bottom surface of body set up the circular filter screen piece that the diameter slightly is greater than the body diameter, the lower square tubular wall of the cladding body all around of filter screen piece is covered by the clamp, still sets up the play appearance mouth that extend the top from the syncline of body section of thick bamboo wall below under on the body. With comparing of prior art, the utility model discloses simple structure, the quality is 2kg only gently, uses and convenient to carry low in cost.
Description
Technical field
This utility model relates to the Benthic ecology environmental studies macrobenthos sample washing device field such as ocean, lake, is specifically related to a kind of simple on-site benthon elutriator.
Background technology
Benthon lives in bed mud for a long time, has regional strong, the features such as transfer ability is weak, for environmental pollution and change usual rare avoidance ability, the destruction of its group and rebuild and need the relatively long time；And majority kind individuality is bigger, it is easy to identification；Meanwhile, variety classes benthon is to the adaptability of environmental condition and the tolerance of the unfavorable factors such as pollution is different with sensitivity；According to These characteristics, utilize the parameters such as benthic population structure, dominant species, quantity can the quality condition of precise reaction water body.
Will not pass through the animal of 500 μm of aperture screen clothes under study for action and be called macrobenthos；Can by 500 μm of aperture screen clothes but can not be meiobenthos by the animal of 42 μm of aperture screen clothes；Can be microbenthos by the animal of 42 μm of aperture screen clothes.
Zoobenthos sample eluriating from mud sample separates the basis being to launch zoobenthos systematic analysis research, is also the important content of the Benthic ecology research such as ocean, lake.Current researcher eluriates mini-Frac test sample with flat mesh screen, and artificial to eluriate workload big, and cost is high, time-consuming takes a lot of work, and wastes water, and after elutriation, the zoobenthos sample washed out often shifts thorough, causes sample to lose, increases experimental error.
The Chinese invention patent that publication number is CN104550095A discloses a kind of automatic washing device for mini-Frac test sample, including housing, described housing is provided with the string bag, also include being located at the outlet above the described string bag, described housing is provided with the water pump for drawing water, described water pump is connected with described outlet by the first water pipe and the second water pipe, is provided with rotary connector between described first water pipe and the second water pipe.Compared with prior art, this invention is provided with water pump, and after water pump is opened, automatic cycle water eluriates sample, saving of work and time；The present invention is provided with three string bags, by arranging the string bag of different pore size, once eluriates and namely may separate out two batches of different size of mini-Frac test samples, and efficiency is high；The current scalable of outlet, and it is provided with protective cover, it is prevented that the organisms such as the insecticide in air are mixed into sample, interference counting, and above the extensible housing of water outlet part, conveniently enclosure interior are operated, and water can recycle, and saves water source.But owing to the water pump of this equipment must be provided with to the power source of its power, or it is diesel engine, or is that electrical network is powered, but owing to sampling generally in the wild, and sample and typically not be fixed on a certain region, it is necessary to often transform sampling point.Electrical network there is no possibility, and diesel engine is bulky, quality weight, adds that this inventive structure is complex, and it is very inconvenient to carry, and additionally this invention cost is also higher.
Summary of the invention
It is an object of the invention to overcome the deficiencies in the prior art, open a kind of simple on-site benthon elutriator, sampling location balance is good, meets body mechanics's feature, has the feature of Simple portable, is specifically adopted the technical scheme that:
A kind of simple on-site benthon elutriator, including cylindric body 4, it is characterized in that: the bottom surface of described body 4 arranges the diameter circular filter screen sheet 1 slightly larger than body diameter, the surrounding cladding lower section barrel of body of filtering net plate 1 is also covered by clip 3, body also sets up from body barrel direction tiltedly under the outlet 2 that extends above.
Further, body barrel arranges a pair handle 5 along the face being perpendicular to outlet axle center and place, body axle center.
Further, clip 3 is open annular, and opening part is arranged to tighten the securing member 6 of clip.
Further, clip is just uniformly arranged more than 3 legs 7 that body lower edge is lifted away from ground 10-20cm.
Further, described filtering net plate is that 0.5mm stainless steel filtering net cuts and forms by mesh.
Further, the diameter of described body is 50-80mm.
Compared with prior art, this utility model simple in construction, light weight is 2kg only, easy to use and carry, cheap.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
Referring to accompanying drawing, a kind of simple on-site benthon elutriator, including cylindric body 4, the bottom surface of described body 4 arranges the diameter circular filter screen sheet 1 slightly larger than body diameter, the surrounding cladding lower section barrel of body of filtering net plate 1 is also covered by clip 3, body also sets up from body barrel direction tiltedly under the outlet 2 that extends above.Body barrel arranges a pair handle 5 along the face being perpendicular to outlet axle center and place, body axle center.Clip 3 is open annular, and opening part is arranged to tighten the securing member 6 of clip, and securing member is that screw adds wing nut.Clip is just uniformly arranged more than 3 legs 7 that body lower edge is lifted away from ground 15cm.Described filtering net plate is that 0.5mm stainless steel filtering net cuts and forms by mesh.The diameter of described body is 70mm.
During use, ocean bed mud is gathered after coming up to fall in this utility model by bottom sampler from seabed, and after being rinsed by bed mud with sea water, marine benthos are stayed on screen cloth, are slowly gone out by biological sample with spoon, outlet along this equipment flows in sample bottle, completes the collecting work of sample.
