Referring to Fig. 1-Fig. 4:
The utility model by eyelid retractor, hold up holder device and absorber and form.
Described eyelid retractor comprises supported rod erecting 1, support rail 6, regulating ring 7, fastening bolt 3 and base 8.
Described supported rod erecting 1 is pipe, and the bottom is connected with base 8 by screw thread; The effect of supported rod erecting 1 provides the fixed position of the continuously adjustable absorber on the vertical direction.Described regulating ring 7 is pipe, internal diameter is slightly larger than supported rod erecting 1 external diameter, guarantee that it can slide along supported rod erecting 1, length slightly is longer than the external diameter of support rail 6, guarantee on the one hand to be connected closely with support rail 6, guarantee that on the other hand regulating ring 7 has large as far as possible sliding distance at supported rod erecting 1 outer wall, each regulating ring 7 can be connected and drive it and slide at supported rod erecting 1 with four support rails 6; Regulating ring 7 outer walls have the internal thread aperture, are threaded with fastening bolt 3; The effect of regulating ring 7 is to drive supporting plate 5 and hold up bar 2 by support rail 6 to be fixed in vertical direction the requirement of experiment position.Fastening bolt 3 is that an end is welded with vertical handle, and the other end has externally threaded bolt, and the threaded end of tool is threaded with regulating ring 7; The effect of fastening bolt 3 is lock adjustment ring 7, support rail 6, supporting plates 5 and hold up bar 2 when regulating ring 7 vertical direction slide into correct position.Described support rail 6 is pipe, and an end and regulating ring 7 outer wall vertical are welded to connect, and the other end and supporting plate 5 are welded to connect, and effect provides supporting plate 5 outside radiation lengths, guarantees that four Parallel Samplings of same plane can not influence each other.Described base 8 is the cylindrical groove of back-off, and the center, top has the circular hole that internal diameter is slightly larger than supported rod erecting 1 external diameter, and is threaded with supported rod erecting 1 by nut; Base 8 act as the standing upright that guarantees that the utility model can be stable in various bottom surfaces.
The described holder device of holding up comprises supporting plate 5 and holds up bar 2.
Described supporting plate 5 is rectangular flat plate, and an end and support rail 6 levels are welded to connect, and level is protruding radially centered by supported rod erecting 1 for the other end, its upper surface with hold up bar 2 and be welded to connect; The effect of supporting plate 5 is to hold up the holder support for the absorption piece 4 that condenses provides.Hold up bar 2 for shaft-like, an end and supporting plate 5 upper surfaces are welded to connect, and the other end is pointed, holds up bar 2 for many and is evenly distributed on supporting plate 5 upper surfaces, the common absorption piece 4 that condenses that supports in pointed top; The effect of holding up bar 2 is supporting plate 5 upper surfaces to be contacted with face to change into a little with the face of absorption piece 4 bottom surfaces of condensing contact with face, contact area is dropped to minimum, avoid for dew in the impact of absorption piece 4 surface condensations of condensing and the impact of absorption piece 4 for the dew absorption of condensing.
Described absorber comprises that a plurality of condensing absorbs piece 4.
The described absorption piece 4 that condenses is the object of regular shape, hold up on the bar 2 for many that are put in same supporting plate 5, its material requires close or consistent with the plant material of Test Field environment, for guaranteeing Experiment Result, requires a plurality of absorption piece 4 materials, shape and quality of condensing of once experiment as far as possible consistent; The effect that absorbs piece 4 of condensing has two aspects: one provides the contact area of dew condensation, the 2nd, the dew after guaranteeing to condense can be condensed as early as possible absorbs piece 4 absorptions, will drop to minimum because of the dew amount that the variation of other influences factor such as temperature, humidity and Air Flow is lost.
An embodiment of the present utility model is: absorb the piece 4 except condensing, integral body can be made by stainless steel.The external diameter of supported rod erecting 1 is 20-50mm, wall thickness 1-3mm, and length is 1.5-2.0m; The external diameter of support rail 6 is 15-30mm, wall thickness 1-3mm, and length is 0.2-0.6m; The internal diameter of regulating ring 7 is 22-52mm, wall thickness 1-3mm, and length is 50-100mm; The length of supporting plate 5 is 100-150mm, and width is 50-100mm, and thickness is 0.5-1.5mm; The diameter of holding up bar 2 is 3-6mm, highly is 30-50mm, and upper end pointed section bit length is to hold up 1/4th to 1/3rd of bar 2 entire length; The external diameter of base 8 is 200-400mm, highly is 50-100mm, and wall thickness is 3-5mm.The material that absorbs piece 4 of condensing can adopt the common shrub of Test Field and arbor to make, and length is 100-150mm, and width is 50-100mm, highly is 50-100mm.Every layer arranges 1-4 according to the experiment needs and condenses and to absorb piece 4, and distance is 200-500mm between layers.
The utility model principle of work is: each that at first will make condenses and absorbs piece 4 and be placed on shady and cool dry place, requires same to condense to absorb 4 hours the twice weighing result difference in piece 4 intervals just can use in 0.02g.Before the period that dew forms, be placed on open-air detection place with this device assembling and after adjusting, and will be very much the position electronic analytical balance weigh and respectively condensing of recording quality absorbs piece 4 and be placed on and hold up on the bar 2, level is answered in each layer position that absorbs after piece 4 is placed of condensing, and answers in case of necessity the usage level chi to proofread and correct.Form later stage period at dew and get respectively to condense and absorb piece 4 and again weigh at a position electronic analytical balance very much, condense the accordingly ratio of the quality difference that absorbs piece 4 and its surface area of front and back is the dew amount ratio of this vertical height in this testing environment.It is for subsequent use that condensing absorption piece 4 after weighing is reapposed over shady and cool dry place.
