Abstract
The utility model relates to a novel groove type solar thermal collector structure. The solar thermal collector structure comprises thermal collecting tubes, a groove type parabolic reflector and a reflector support used for fixing the groove type parabolic reflector. The solar thermal collector structure is characterized in that the thermal collecting tubes are fixed on a support special for the thermal collecting tubes, and the support special for the thermal collecting tubes is fixed on the ground so that the thermal collecting tubes can be kept still. Concretely, a hollow rotating shaft scheme and a solid rotating shaft scheme are provided and aim to make the groove type parabolic reflector rotate around the fixed thermal collecting tubes through the rotating shaft for condensing light, and therefore the defect that in the prior art, because thermal collecting tubes need moving, the thermal collecting tubes and a main oil pipe need to be movably connected is overcome; due to the novel groove type solar thermal collector structure, the thermal collecting tubes and the main oil pipe can be rigidly connected, and the risk of leaking conduction oil and the like is avoided.
Description
Technical field
This is practical newly relates to a kind of solar heat gathering-device, particularly about a kind of novel slot solar thermal collector structure.
Background technology
In prior art, as follows about groove type solar collecting system technological overview.
Solar energy heating is the core component of Solar Energy Heat Utilization System, and solar thermal collector absorbs the light of solar radiation, produces very large heat energy, and power is endlessly provided.Different hot-water heating systems solar thermal collector used is different, and heat collector external form has day dull and stereotyped, has vacuum tube, and they have special heat sink, absorb solar radiation, change into heat energy, the heat-conducting fluid in heating heat collector.Heat collector, according to the difference of temperature, is divided into low temperature, middle temperature, high temperature, and different standards has different classification certainly, such as, also having tracking heat collection device and non-tracking heat collection device, according to heat collector, whether whole day is divided into around solar motion for it.In our life, modal solar thermal collector, is exactly two kinds of flat-plate solar collector and vacuum tube solar heating elements.Solar thermal collector is exactly to absorb solar radiation energy and to the device of working medium transferring heat in a word.
Groove type solar collecting system, generally consists of groove type paraboloid reflective mirror, support, hot receiver, driving mechanism and follow-up control apparatus.Groove type paraboloid reflective mirror reflects sunshine and focuses on thermal-collecting tube, the heat-conducting fluid in heating thermal-collecting tube, thereby transferring heat energy.Conventionally, an emissions groove formula solar thermal collection system is called one group of groove type solar combination.
