Abstract
The invention discloses an outer protecting cover for a sealing portion of an evacuated solar collector tube. The outer protecting cover is mainly characterized in that a cover body of the outer protecting cover is a strip-shaped thin-wall plate when unfolded, buckling holes are formed in one end of the cover body, buckling sheets distributed corresponding to the buckling holes are arranged at the other end of the cover body, and a plurality of protrusions which protrude in the same direction and are distributed at intervals and used for being matched with wave joint grooves of a corrugated tube are arranged in the length direction of the cover body which is the strip-shaped thin-wall plate and located in the middle of the cover body in the width direction. The outer protecting cover has the advantages of being simple in structure, practical and convenient to use, playing a role in effectively protecting the sealing portion of an inner stainless steel tube and an outer glass tube and the corrugated tube, and the like.
Description
Technical field
The present invention relates to a kind of outer protective cover of solar vacuum heat-collecting tube sealing position, belong to solar thermal utilization equipment technology.
Background technology
Solar energy heat collection pipe sealing-in position of the present invention, comprise pipe and glass tube outer tube in stainless steel (316L), the thin-walled sealing-in pipe be welded to connect by specific method for sealing (method such as disclosed in Chinese patent CN102219400B) and the sealing-in position with outer glass tube thereof, and the bellows be located between adjacent two adpting flanges is at interior position.
Because described thin-walled sealing-in pipe (containing stainless steel and kovar alloy sealing-in pipe) and bellows, be thin-wall member (wall thickness < 1.5mm), thus its antibody Monoclonal ability is all lower.Like this, described solar vacuum heat-collecting pipe turns in journey in its storage and traffic flow, described sealing-in position just inevitably suffers the injury of external force (be out of shape or break), and under its duty, be coated on the heat-insulation material of periphery, sealing-in position, described thermal-collecting tube two ends, can embed in the node groove of bellows again, affect the normal work of bellows under daytime heat night cold-peace seasonal variations condition, even cause the fracture of bellows.
For this reason, for the defect existing for prior art, take measures to protect the safety of described solar vacuum heat-collecting tube sealing position and bellows, just become very real research and development problem.
Summary of the invention
It is simple that the present invention aims to provide a kind of structure, and the outer protective cover at practical and convenient solar vacuum heat-collecting tube sealing position, to overcome the deficiencies in the prior art.
The technical scheme that the present invention realizes its object is:
A kind of outer protective cover of solar vacuum heat-collecting tube sealing position, the deployed condition of its cover body is strip-shaped thin wallboard part, snapping hole is had in its one end, and the snapping sheet of tackling layout with snapping hole is mutually had at its other end, be positioned at the middle part of its width along strip-shaped thin wallboard part cover body length direction, have the projection of several protruding and being used for of having spacing arranged apart and the node groove phase configuration of bellows to same direction;
Under operating mode; described strip-shaped thin wallboard part cover body is posted the periphery at pipe and outer glass tube sealing-in position in stainless steel; by implementing circle circle to it, its projection is entrenched in the node groove of bellows; again the snapping hole of its one end and the snapping sheet of its other end are plugged together snapping, namely form the outer protective cover at sealing-in position, solar vacuum heat-collecting pipe two ends.
Can be known by above given technical scheme; due to the existence of described outer protective cover; while guarantee is to the insulation of solar vacuum heat-collecting pipe two ends; the described thin-wall stainless steel of available protecting and with the sealing-in position of glass tube and the safety of bellows; simultaneously; under its operating mode; can at the coated heat-insulation material of described outer protective cover outer surface; to avoid because heat-insulation material enters in the node groove of bellows; and affect the normal work of bellows, thus achieve object of the present invention.
Further innovative point of the present invention is:
Described is raised with 6, and 6 projections are equidistantly arranged apart along strip-shaped thin wallboard part cover body length direction.But be not limited to this.Described equidistantly arranged apart, also can be that the central angle that waits under its circle round shape state is arranged.
Described strip-shaped thin wallboard part cover body is plastic part or alumiaum article or copper fitting or stainless steel product.And described plastic part preferably weather-proof nylon products, or weather-proof alloy plastic product, and the plastic part that described plastic part system integral molded plastic is shaping.
When described cover body is metallic article, described projection is by described metal band-shaped thin-walled plate cover body, formed by Punching Technology and with described cover body each other one.
Described snapping hole and snapping sheet respectively have 2, and all in mutually adaptive strip, and described 2 snapping holes and 2 snapping sheets have spacing arranged apart along described cover body width respectively.But being not limited to this, described snapping hole and snapping sheet, also can be the frame mode being similar to button pair.
On the surface of described aluminium matter strip-shaped thin wallboard part cover body, there is the anodic oxide coating for improving its weather-proof ability.Due to the existence of anodic oxide coating, insulation weather resistance of the present invention and intensity can be strengthened, effectively extend its service life.
The thickness of described aluminium or copper or stainless steel banded thin-walled part part cover body within the scope of 0.5 ~ 2mm, but is not limited to this.
After technique scheme is implemented in full; the structure that the present invention has is simple; practical safety, good to the defencive function of pipe and outer glass tube sealing-in position and bellows in stainless steel, it is apparent for reducing features such as the impacts of described thermal-collecting tube effective length.

Fig. 2 is that the schematic diagram of outer protective cover justified into by deployed condition strip-shaped thin wallboard part cover body 1 circle as shown in Figure 1;
Fig. 3 is the schematic diagram of the present invention and solar vacuum heat-collecting pipe assembled state.
Detailed description of the invention
Below contrast accompanying drawing, by the description of detailed description of the invention, the invention will be further described.
A kind of typical detailed description of the invention, as shown in accompanying drawing 1,2,3.
A kind of outer protective cover of solar vacuum heat-collecting tube sealing position, the deployed condition of its cover body 1 is strip-shaped thin wallboard part, snapping hole 2 is had in its one end, and have at its other end and tackle with snapping hole 2 phase the snapping sheet 3 arranged, be positioned at the middle part of its width along strip-shaped thin wallboard part cover body 1 length direction, have the projection 4 of several protruding and being used for of having spacing arranged apart and the node groove 5-1 phase configuration of bellows 5 to same direction;
Under operating mode; described strip-shaped thin wallboard part cover body 1 is posted the periphery at pipe and outer glass tube sealing-in position in stainless steel; by implementing circle circle to it, its projection 4 is entrenched in the node groove 5-1 of bellows 5; again the snapping hole 2 of its one end is plugged together snapping with the snapping sheet 3 of its other end, namely form the outer protective cover at solar vacuum heat-collecting tube sealing position (comprising bellows).
Described projection 4 has 6, and 6 projections 4 are equidistantly arranged apart along strip-shaped thin wallboard part cover body 1 length direction.
