Abstract
Disclosed are a center portion control (CPC) secondary reflection device with an opening in the top portion and a fixing device of the CPC secondary reflection device. The CPC secondary reflection device is in a compound paraboloid structure with the opening in the middle of the top portion, and is made of silver-plated or aluminum-plated glass or mirror stainless steel or mirror aluminum or film-coated injection molding type materials. The fixing device of the CPC secondary reflection device comprises a fixture which fixes the opening in the middle of the top portion of the secondary reflection device. The lateral face of the secondary reflection device and the lower edge of the secondary reflection device are fixed by supporting plates. The shape of the inner surface of the supporting plate is matched with the shaped of the outer surface of the secondary reflection device, the lower portion of the lateral face of the supporting plate is provided with a lower concave angle which is used for enabling the lower edge of the secondary reflection device to be inserted into the lower concave angle to be fixed, and channel steel which is used for supporting the supporting plate of the secondary reflection device is arranged at two ends of the outer portion of the supporting plate of the secondary reflection device. A glass outer pipe of a heat-collecting pipe is prevented from contacting and colliding with the secondary compound paraboloid reflection device, and therefore not only is the reflection function of the area of a main part of the secondary compound paraboloid reflection device maintained, but also secondary reflection condensation effect and photo-thermal exchanging efficiency are guaranteed.
Description
Technical field
The present invention relates to technical field of solar utilization technique, be specifically related to a kind of open-topped CPC secondary reflection device and fixture thereof.
Background technology
The energy resources reserves of China allow of no optimist, and per capita resources is not abundant.Many places lack the conventional energy resource resource, but solar energy resources is abundant.For improving solar energy thermal-power-generating efficient, need to improve performance and the thermal transition efficient of each assembly of solar energy thermal-power-generating, parts.Line focusing solar collector tube and secondary reflection plate are one of solar energy thermal-power-generating critical components, can greatly improve Salar light-gathering ratio and light-thermal conversion efficiency.Need to carry out primary study and concern.
Present glass-metal vacuum heat collection pipe generally only is used in the trough type solar power generation technology, and it focuses on solar light on the thermal-collecting tube by parabolic mirror, and secondary reflection device is not set.For the Fresnel solar energy reflection unit, focus on difficulty for reducing, increase simultaneously optically focused ratio and light gathering efficiency, need to be provided with secondary reflection device, how to assemble but adopt which kind of form to reach, become technological difficulties.If use the plated film steel pipe that does not have glass, its heat loss is larger.If use the glass-metal vacuum heat collection pipe, should guarantee the accurate shape of secondary reflection minute surface, be convenient to again assembling, improve the equipment reliability of operation.Damage otherwise thermal-collecting tube is produced, or spotlight effect is poor normal the and efficient operation of the equipment that affects.
Summary of the invention
For solving above-mentioned problems of the prior art, the object of the present invention is to provide a kind of open-topped CPC secondary reflection device and fixture thereof, the collision of having avoided collector tube glass outer tube and secondary composite parabolic reflection unit with contact, both keep the major part of secondary composite parabolic reflection unit and the reflection function of area, guaranteed again effect and the light-thermal conversion efficiency of secondary reflection concentrating.
For achieving the above object, the technical solution adopted in the present invention is:
A kind of open-topped CPC secondary reflection device, described secondary reflection device 3 is the composite paraboloid structure of crown center opening.
Described secondary reflection device 3 adopts glass, mirror face stainless steel, specular aluminium or plated film injection moulding class material silver-plated or that aluminize.
A kind of fixture of open-topped CPC secondary reflection device, comprise fixedly secondary reflection device 3, the secondary reflection device anchor clamps 6 of crown center opening, the side of secondary reflection device 3 and lower limb are fixing by secondary reflection device gripper shoe 4, the external surface shape of the shape of the inner surface of described secondary reflection device gripper shoe 4 and secondary reflection device 3 is suitable, the bottom, side has lower re-entrant angle so that the lower limb of secondary reflection device 3 inserts in the lower re-entrant angle fixing, be provided with to support the channel-section steel 5 of secondary reflection device gripper shoe 4 at the outside two ends of secondary reflection device gripper shoe 4, base 1 is fixed on the channel-section steel 5 at two ends.
Because the metal inner pipe of thermal-collecting tube need to be positioned at the focal position of secondary composite parabolic, therefore the outer glassy layer of vacuum heat collection pipe can contact or hinder the composite parabolic of standard, for thermal-collecting tube and secondary reflection device can be assembled smoothly, and the unlikely breakage that breaks up that is in operation.The present invention is at secondary reflection device crown center opening, the collision of having avoided collector tube glass outer tube and secondary composite parabolic reflection unit with contact, both keep the major part of secondary composite parabolic reflection unit and the reflection function of area, guaranteed again effect and the light-thermal conversion efficiency of secondary reflection concentrating.
