Abstract
The invention discloses a kind of solar vacuum heat-collecting pipe expansion compensation components for belonging to solar energy heat utilization technical field.The expansion compensation component includes bellows, endless metal slot, metal end, metal liner, Vibrant buffer bracket and bellows hood for protecting rider.The expansion compensation component can not only compensate the differential expansion of thermal-collecting tube metal inner pipe and cover glass tube in use, the vibration of cover glass tube can also be buffered by Vibrant buffer bracket, blocks dust particle enters between bellows and metal tube simultaneously, reduce vacuum leak risk caused by dust granule abrasion, increased bellows hood for protecting rider avoids the case where leading to vacuum leak due to focus irradiation bellows, also simplifies thermal-collecting tube installation process.
Description
Technical field
The invention belongs to solar energy heat utilization technical fields, and in particular to a kind of solar vacuum heat-collecting pipe expansion benefit
Repay component.
Background technique
With the rapid development of science and technology, demand of the people to the energy increasingly increases.Solar groove type heat power generation at
Hot spot concerned by people.High temperature solar evacuated collector tube is the core component in groove type solar power station, has obtained the wide of people
General research.Expansion compensation component is the important component of evacuated collector tube, it is primarily served in the compensation thermal-collecting tube course of work
The differential expansion of metal inner pipe and cover glass tube.Can also exist during the work time due to heat-conducting medium in thermal-collecting tube use process
Multiphase coexistence and thermal-collecting tube is caused to vibrate, and this vibration is enough to cause cover glass tube damaged.Sand and dust in environment also can be into
Enter the gap between the bellows and metal liner of expansion compensation component, in turn result in the abrasion to bellows or metal liner from
And vacuum leak is caused to lead to thermal-arrest tube failure.
To avoid the sunlight direct projection bellows focused in use from turn resulting in very so as to cause bellows scaling loss
Sky leakage, usually all can install hood for protecting rider additional outside thermal-collecting tube both ends, this not only increases the workload of thermal-collecting tube fixing link,
And outside installation hood for protecting rider can due to the vibration in the thermal-collecting tube course of work, the natural environment influences such as wind and weather and take off
It falls.Therefore it needs to find one kind and can either buffer the vibration generated due to heat-conducting medium multiphase coexistence, and sand and dust can be stopped
Particle enters bellows and metal liner gap, while can reliably block the method that bellows is not focused sunlight scaling loss.
Summary of the invention
The present invention is in order to overcome disadvantage existing in the prior art, and its purpose is to provide a kind of solar vacuum heat-collecting pipes
With expansion compensation component.
To achieve the goals above, the technical solution adopted by the present invention is as follows:
A kind of solar vacuum heat-collecting pipe expansion compensation component, including bellows 1, endless metal slot 2, metal end 3,
Metal liner 4, Vibrant buffer bracket 5 and bellows hood for protecting rider 6；One end of the endless metal slot 2 and bellows 1 and metal
Bushing pipe 4 is connected by welding manner；The metal end 3 is connected with the other end of bellows 1 by welding manner, while gold
Belong to end cap 3 end face circumferentially pass through welding uniformly arrangement Vibrant buffer bracket 5, and metal end 3 towards bellows end face with
Bellows hood for protecting rider 6 passes through welded connecting.
The bellows 1 forms by pressing one-time or passes through sheet metal welding fabrication.
The material of the bellows 1 is 304 stainless steels or 316L stainless steel.
The bellows 1 with a thickness of 0.1mm-0.3mm.
The Vibrant buffer bracket 5 is L-type, with a thickness of 1mm-5mm, width 2mm-5mm.
The Vibrant buffer bracket (5) is 0.5mm-3mm in the spacing that metal end (3) end face is circumferentially arranged, with gold
Belong to the angle of end cap (3) end face are as follows: 10 ° -45 °.
The material of the bellows hood for protecting rider 6 is 304 stainless steels or 316L stainless steel.
The thickness of the bellows hood for protecting rider 6 are as follows: 1mm-4mm.
The invention has the benefit that can not only to compensate evacuated collector tube golden in use for the expansion assembly
Belong to the differential expansion of inner tube and cover glass tube, can also be buffered caused by heat-conducting medium multiphase coexistence and be shaken by Vibrant buffer bracket
It is dynamic, to reduce cover glass tube due to breakage risk caused by vibrating, and Vibrant buffer bracket is closely packed on metal end, energy
Enough blocks dust particles enter the clearance space between bellows and metal liner, cause to reduce since dust enters abrasion
Expansion compensation component failures.Bellows hood for protecting rider is connect with welding manner with metal end, and is in evacuated collector tube vacuum
In interlayer, the irradiation for blocking focusing sunlight to bellows can be reliably realized.
