Abstract
A sampling net collecting device of plankton comprises an upper rigid cylinder, a lower rigid cylinder, a funnel-shaped rigid cylinder, a rigid sleeve head, rigid connecting bars, silk yarn and connecting screws. The sampling net collecting device of the plankton is characterized in that groove openings are formed close to an upper edge and a lower edge of the upper rigid cylinder, the inner diameter of the lower rigid cylinder is equal to that of the upper rigid cylinder, the outer diameter of the lower rigid cylinder is equal to that of the upper rigid cylinder, a groove opening is formed close to an upper edge of the lower rigid cylinder, the lower portion of the lower rigid cylinder is provided with external threads, the upper end of the funnel-shaped rigid cylinder is provided with inner threads, the inner threads are connected with the external threads of the lower rigid cylinder in a screwing mode. A small semicircular water outlet is formed in the bottom of a small cylinder arranged at the lower portion of the funnel-shaped rigid cylinder, a threaded hole is formed in the middle of the bottom of the small cylinder, a semicircular water outlet is formed in the bottom of the rigid sleeve head, a threaded hole is formed in the middle of the bottom of the rigid sleeve head, the rigid sleeve head is fixed on the funnel-shaped rigid cylinder through the connecting screws, the silk yarn is sewed into a cylinder, an upper edge and a lower edge of the silk yarn cylinder are respectively fixed with the groove openings of the upper rigid cylinder and the lower rigid cylinder through strings or clamping rings, the upper rigid cylinder and the lower rigid cylinder are fixedly connected with each other through two or three rigid connecting bars.
Description
Technical field
The utility model relates to the gathering unit of marine organisms investigation usefulness.
Background technology
China in 2007 promulgates new standard of marine survey (GB12763-2007), to replace 1991 editions investigation specifications.In the 6th part in this standard (investigation of GB12763.6-2007 marine organisms), Sampling nets has been stipulated in plankton investigation, but the gathering unit when netting gear take a sample is only used " sleeve pipe " description.In actual the use, netting gear is made and can be processed according to relevant criterion, but gathering unit each is variant.At present widely used gathering unit is the conical hopper formula, and the bottom has aperture, and it is very not convenient operate, and bigger than normal or when having other foreign matters to enter, the difficult taking-up of interior thing brings all difficulties to sampling when biomass.At present, go back simple, efficient, the cheap biological sampling net gathering unit of neither one.
Summary of the invention
The utility model need to solve provides a kind of plankton sampling network gathering unit, can overcome gathering unit bigger than normal or when having other foreign matters to enter at biomass, and interior thing is difficult for the problem of taking out.
The technical solution of the utility model is pullover by upper rigid cylinder, lower rigid cylinder, infundibulate rigid cartridge, rigidity, the bar that is rigidly connected, yarn thin,tough silk and attachment screw form, there are notch in the nearly top, the bottom that it is characterized in that rigid cylinder, the notch of top is used for connecting netting gear, and following notch twines and the fixed yarn thin,tough silk; The internal diameter of lower rigid cylinder, external diameter are isometrical with internal diameter, the external diameter of upper rigid cylinder respectively, and there is notch the nearly top of lower rigid cylinder, are used for twining and fixed yarn thin,tough silk bottom, and the bottom of lower rigid cylinder has external screw thread to be connected with the infundibulate rigid cartridge; Infundibulate rigid cartridge upper end has a cylindrical section body, cylinder to have the external screw thread of internal thread and lower rigid cylinder to screw, and infundibulate rigid cartridge bottom connects a roundlet column casing, and little semilune delivery port is arranged at the bottom of roundlet column casing, and the bottom center of roundlet column casing has screwed hole; The pullover one-tenth cylindrical shape of rigidity is inserted in the stack shell of infundibulate rigid cartridge bottom roundlet column casing, and half-moon-shaped delivery port is arranged at the pullover bottom of rigidity, and the pullover bottom center of rigidity has screw hole; Attachment screw screws in the screwed hole of the roundlet column casing bottom center of infundibulate rigid cartridge by the screw hole of the pullover bottom center of rigidity, with the pullover infundibulate rigid cartridge that is fixed in of rigidity; The yarn thin,tough silk is stitched into cylindrical drum, and yarn thin,tough silk order counts specification and employed sampling network is equal to, and strap is made respectively by bottom on the yarn thin,tough silk cylindrical drum, and fixes with the notch of cord or snap ring and upper rigid cylinder and lower rigid cylinder; The outer wall of upper rigid cylinder and lower rigid cylinder adopts 2 symmetrical or bars that are rigidly connected that 3 equal angles distribute by rivet or is welded and fixed the upper and lower rigid cylinder that is connected gathering unit.
The utility model can be in conjunction with the sampling net actual conditions, make the gathering unit of all size, have easy and simple to handle, difficult drop-off, and the advantage that can use for a long time.

Embodiment
The utility model (referring to Fig. 1) is pullover 4 by upper rigid cylinder 1, lower rigid cylinder 2, infundibulate rigid cartridge 3, rigidity, the bar 6 that is rigidly connected, yarn thin,tough silk 7 and attachment screw 5 form.There is notch on the near upper and lower limit of upper rigid cylinder (referring to Fig. 2), and the notch of top is used for connecting netting gear, and following notch is used for twining and the fixed yarn thin,tough silk.The internal diameter of lower rigid cylinder (referring to Fig. 3), external diameter are isometrical with internal diameter, the external diameter of upper rigid cylinder respectively, and there is notch the nearly top of lower rigid cylinder, are used for twining and fixed yarn thin,tough silk bottom, and the bottom of lower rigid cylinder has external screw thread to be connected with the infundibulate rigid cartridge.A cylindrical section body is done on infundibulate rigid cartridge (referring to Fig. 4) top, cylinder has the external screw thread of internal thread and lower rigid cylinder to screw, infundibulate rigid cartridge bottom connects a roundlet column casing, little semilune delivery port is arranged at the bottom of roundlet column casing (referring to Fig. 5), and the bottom center of roundlet column casing has screwed hole.The pullover one-tenth cylindrical shape of rigidity is inserted in the stack shell of infundibulate rigid cartridge bottom roundlet column casing, and half-moon-shaped delivery port is arranged at the pullover bottom of rigidity, and the pullover bottom center of rigidity has screw hole.Attachment screw screws in the screwed hole of roundlet column casing bottom center of infundibulate rigid cartridge with the pullover infundibulate rigid cartridge that is fixed in of rigidity by the screw hole in the middle of the pullover bottom of rigidity.The yarn thin,tough silk is stitched into cylinder barrel shaped, and yarn thin,tough silk order counts specification and employed sampling network is equal to, and strap is made respectively by bottom on the yarn thin,tough silk cylindrical drum, and fixes with the notch of cord or snap ring and upper rigid cylinder and lower rigid cylinder.The bar that is rigidly connected can adopt straight arc or vertical bar shaped, the upper end also can be made into the roundlet annular, and the bar that is rigidly connected that upper rigid cylinder and the outer wall of lower rigid cylinder adopt 2 symmetrical or 3 equal angles distributions is by rivet or be welded and fixed the upper and lower rigid cylinder that is connected gathering unit.The utility model goes to the pullover bottom of rigidity delivery port first infundibulate rigid cartridge bottom entity part before sampling, and tightens with attachment screw, in case the sampling thing spills.After the hauling, unclamp attachment screw, the roundlet column casing of infundibulate rigid cartridge bottom is alignd with the pullover delivery port of rigidity, so that the sampling logistics goes out, or directly the infundibulate rigid cartridge is separated with lower rigid cylinder, i.e. object in the pourable infundibulate rigid cartridge.
