Description
Technical field
The utility model relates to a kind of beam condensing unit, is specifically related to a kind of groove type solar concentrating collector.
Background technology
People have obtained progress with rapid changepl. never-ending changes and improvements to the utilization of solar energy at present, and solar water heater, solar panel etc. have been accomplished scale production and commercial operations as the typical case of utilization of new energy resources.The solar energy thermal-power-generating technical research starts from 20 middle of century, but because technology was still immature at that time, develops slower.In recent years, along with the continuous growth of energy demand and the attention of environmental pollution and weather variation issue, in worldwide, started the upsurge of solar energy thermal-power-generating research.Solar heat power generation system mainly is made up of concentrator, heat collector, heat accumulation/combustion-compensating device and thermal electric generator.With the solar photovoltaic generating compared with techniques, the maximum advantage of solar energy thermal-power-generating technology is to use cheap heat accumulation/combustion-compensating device to realize the free of discontinuities operation in power station, and is continuously user's power supply.
In the solar energy light gathering and heat collecting technology, traditional groove type paraboloid concentrator is used the most extensive and ripe.The groove type paraboloid concentrator has obtained successful utilization in many large-scale solar heat power stations, and under the condition of accurately control, it can obtain the high temperature more than 400 ℃.But there are two major defects in this type concentrating collector: 1. device is very high to solar tracking precision and paraboloidal requirement on machining accuracy, because in case the light that is reflected can not arrive receiver, just will become invalid light; 2. the high temperature solar receiver is installed in the top of reflective surface, is unfavorable for the installation and the insulation of receiver.For large-scale plant, it is very difficult overcoming above-mentioned shortcoming.
The utility model content
The purpose of the utility model is to overcome above-mentioned deficiency of the prior art, and a kind of groove type solar concentrating collector is provided, and it is reasonable in design, and is simple in structure, stable, and collecting efficiency is high, is convenient to dismounting, maintenance, and production cost is low, is convenient to promote the use of.
For realizing above-mentioned purpose; The technical scheme that the utility model adopts is: a kind of groove type solar concentrating collector; It is characterized in that: comprise the bottom land parabolic condenser; The straight line place, parabolic focus place of said bottom land parabolic condenser is provided with receiver; Said bottom land parabolic condenser upside is symmetrically arranged with the secondary reflection level crossing, and said each secondary reflection level crossing upside is provided with the combination parabolic condenser, and the virtual focus point of said combination parabolic condenser is positioned at the secondary reflection level crossing midline position on its opposite.
Said combination parabolic condenser upper end bore is greater than 1 meter.
Said combination parabolic condenser bottom end opening place is provided with and is used to protect the transparent plastic of receiver dull and stereotyped.
The utility model compared with prior art has the following advantages:
(1) design of this groove type solar concentrating collector is very reasonable, simple in structure, compact, stable.
(2) this groove type solar concentrating collector receiver is positioned at the bottom of this device, and collecting efficiency is very high, and is convenient to dismounting, maintenance.
(3) a lot of parts of this groove type solar concentrating collector all are convenient to produce, buy very much, thereby its production cost is very low, is convenient to promote the use of.
Through accompanying drawing and embodiment, the utility model is done further detailed description below.

Description of reference numerals:
The 1-sunshine; 2-makes up parabolic condenser; 3-secondary reflection level crossing;
4-bottom land parabolic condenser; The 5-receiver.
The specific embodiment
A kind of groove type solar concentrating collector as shown in Figure 1; Comprise bottom land parabolic condenser 4; The straight line place, parabolic focus place of said bottom land parabolic condenser 4 is provided with receiver 5; Said bottom land parabolic condenser 4 upsides are symmetrically arranged with secondary reflection level crossing 3, and said each secondary reflection level crossing 3 upside are provided with combination parabolic condenser 2, and said combination parabolic condenser 2 upper end bores are greater than 1 meter.The virtual focus point of said combination parabolic condenser 2 is positioned at secondary reflection level crossing 3 midline positions on its opposite, and said combination parabolic condenser 2 bottom end opening places are provided with and are used to protect the transparent plastic of receiver 5 dull and stereotyped.
The course of work of the utility model groove type solar concentrating collector is: at first this groove type solar concentrating collector is installed on the solar tracking device; Under the solar tracking device effect; Sunshine 1 uses this device of vertical irradiation; When sunshine 1 is radiated at combination 2 last times of parabolic condenser, the sunshine 1 after converging is after 3 reflections of secondary reflection level crossing, and the light focus collects on the receiver 5.When sunshine 1 is radiated at 4 last times of bottom land parabolic condenser, drop on equally on the receiver 5 through bottom land parabolic condenser 4 its focuses of reflection back.
The above; It only is the preferred embodiment of the utility model; Be not that the utility model is done any restriction; Every according to the utility model technical spirit to any simple modification, change and equivalent structure transformation that above embodiment did, all still belong in the protection domain of the utility model technical scheme.
