Description
Technical field
This utility model relates to a kind of plankton layered sampling device, and specifically a kind of simple and easy marine environment investigation plankton layered sampling device, belongs to plankton sampler field.
Background technology
Start from national ocean generaI investigation in 1958, in China's marine organisms investigation, plankton gathers and has been used up the same class netting gear that " marine monitoring specification " (GB17378.7-2007) and " standard of marine survey " (GB/T12763.6-2007) specifies, namely 30m adopts shallow water I, II, type III plankton net, 30m to adopt large, medium and small type plankton net to make vertical or sectional sampling with territory, deep-sea with neritic zone, if any particular/special requirement, other netting gears optional.According to survey objective, object of study, and the spring layer distribution situation such as on-the-spot temperature, salt, sometimes need to carry out vertical fragmentation trawlnet, i.e. stratified sampling.Mostly existing stratified sampling netting gear is to adopt the mode closing network interface, can only gather a level sample every time, cumbersome and time consuming.
Understanding the planktonic kind composition sum quantitative change merit of different water levels in waters is one of biological oceanography basic survey observation project, its usual employing one can control plankton net and open, the device dead lock cut out carries out stratified sampling, normally used dead lock adopts the reverse spine hook self-locking mechanism of lever, due to the power-saving function that lever is risen, this device is made to have higher sensitivity, thus when discharging load, use the lighter hammer (0.5kg) that makes just can open dead lock, on the other hand, control safety effect by reverse spine hook self-locking mechanism, make dead lock do not hit make hammer before will not there is automatically-unhooked or automatic blocking phenomenon, ensure that dead lock performance height reliability.Latch is adopted to change mechanism, easy to loading and unloading, make operation on the sea. work is greatly simplified.
Summary of the invention
In order to solve the deficiency that prior art exists, the utility model discloses a kind of simple and easy marine environment investigation plankton layered sampling device, for realizing this purpose, the technical solution adopted in the utility model is:
A kind of simple and easy marine environment investigation plankton layered sampling device, including the flexible plankton net clothing lengthened, the bottom of flexible plankton net clothing arranges spacer screen pipe, unlike the prior art: also include the frame linking of a suspension flexibility plankton net clothing, frame linking arranges first, second, third dead lock, first, second, third dead lock connects first, second, third pull rope respectively, and first, second, third pull rope sheathed first, second, third makes hammer respectively；Flexible plankton net clothing above-below direction is uniformly distributed first, second, third button-type rope network interface, and first, second, third dead lock coordinates first, second, third cinch cord and first, second, third weight to control the opening and closing of first, second, third button-type rope network interface.
Further, the drum rim of equally distributed annular array on flexible plankton net clothing.
Further, first, second, third pull rope arranges depth of water scale.
Compared with prior art, this utility model simple in construction, operation and easy to carry, it is possible to the layered sampling device that multiple disposable collections of water layer sample are completed, it is ensured that the seriality of stratified sampling, save a large amount of human and material resources and financial resources, improve work efficiency.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
Referring to Fig. 1, a kind of simple and easy marine environment investigation plankton layered sampling device, including the flexible plankton net clothing 1 lengthened, the bottom of flexible plankton net clothing 1 arranges spacer screen pipe 9, one frame linking 2 hanging flexible plankton net clothing, frame linking 2 arranges first dead lock the 21, second dead lock the 22, the 3rd dead lock 23, first, second, third dead lock connects first pull rope the 31, second pull rope the 32, the 3rd pull rope 33 respectively, first, second, third pull rope sheathed first makes hammer 41 respectively, second makes hammer the 42, the 3rd make hammer 43；Flexible plankton net clothing above-below direction is uniformly distributed first button-type rope network interface the 51, second button-type rope network interface the 52, the 3rd button-type rope network interface 53, and first, second, third dead lock coordinates first cinch cord the 61, second cinch cord the 62, the 3rd cinch cord 63 and first weight the 71, second weight the 72, the 3rd weight 73 to control the opening and closing of first, second, third button-type rope network interface.The drum rim of equally distributed annular array on flexible plankton net clothing.Wherein the second pull rope arranges depth of water scale.
In detail below with 4m length flexibility plankton net clothing, gathering 0-5m, 5-10m, 10-15m, 15-20m water layer plankton sample is example explanation.
After off line, when network interface arrives depth of water 20m water layer (being read by the second pull rope 32 with depth of water scale), at the uniform velocity hauling, when network interface arrives depth of water 12m water layer, the 3rd discharged on the 3rd pull rope 33 makes hammer 43, hit out the 3rd dead lock 23, discharge the 3rd weight 73, the 3rd cinch cord 63 is tightened up under the 3rd weight action of gravity, the 3rd button-type rope network interface 53 is made to strain, flexible plankton net clothing is closed at the 3rd button-type rope network interface place, is the plankton sample of depth of water 15-20m water layer in the etting that this place is following.
Continue at the uniform velocity hauling, when network interface arrives depth of water 8m water layer (being read by band depth of water scale the second pull rope 32), first discharged on the first pull rope 31 makes hammer 41, hit out the first dead lock 21, discharge the first weight 71, under the first weight action of gravity, tighten up the first cinch cord 61, make the first button-type rope network interface 51 strain, etting is closed at this place, is the plankton sample of depth of water 10-15m water layer in the first button-type rope network interface the less than 51, the 3rd button-type rope network interface more than 53 etting.
Continue at the uniform velocity hauling, when network interface arrives depth of water 4m water layer (being read by band depth of water scale the second pull rope 32), second discharged on the second pull rope 32 makes hammer 42, hit out the second dead lock 22, discharge the second weight 72, under the second weight action of gravity, tighten up the second cinch cord 62, make the second button-type rope network interface 52 strain, etting is closed at this place, below this place, is the plankton sample of depth of water 5-10m water layer in the first button-type rope network interface more than 51 etting.
Continue at the uniform velocity hauling to leaving the water surface, collect 15-20m, 10-15m, 5-10m, 0-5m water layer plankton sample successively from net bottom pipe 9.
Last it is noted that the foregoing is only an embodiment of the present utility model; not in order to limit this utility model; the concrete weight of such as netting-length of the present utility model and weight can be determined according to concrete collection depth of water water layer; all within spirit of the present utility model and principle; any amendment of being made, equivalent replacement, improvement etc., should be included within protection domain of the present utility model.
