Technical field
The invention belongs to field of solar energy utilization, relate in particular to a kind of Salar light-gathering dish tracking transducer.
Background technology
Disc type solar energy system is a kind of comparatively effectively form during sun power utilizes.But near optically focused dish hot spot, in prior art, never have good sensor to facula position carry out directly, the method for Measurement accuracy, thereby affected optically focused dish to the sun towards tracking, and then affect making full use of of luminous energy.
Summary of the invention
Object of the present invention is just to provide a kind of solar energy tracking sensor that is specifically designed to high-strength light detection and photosensitive conversion, to use under near condition optically focused dish high temperature hot spot.
Specifically, the technical solution used in the present invention is as follows:
A kind of Salar light-gathering dish tracking transducer, comprise the semi-transparent solid stick thing of printing opacity, connecting pipe 3 and light sensor 4, it is characterized in that, the semi-transparent solid stick thing of printing opacity is divided into more than two sections, with connecting pipe 3 parcels, be connected, and be separated between at least one pair of adjacent semi-transparent solid stick thing of two sections of printing opacities, in leaning on the semi-transparent solid stick thing of two sections of printing opacities of outermost, the top of one section of semi-transparent solid stick thing 2 of printing opacity forms optically focused sunshine import 1 and another section of semi-transparent solid stick thing 5 connection light sensors 4 of printing opacity.
As a preferred embodiment, the number of the semi-transparent solid stick thing of printing opacity is two sections.
Preferably, at least one in the semi-transparent solid stick thing of printing opacity is glass bar.
For the consideration of the semi-transparent solid stick thing of printing opacity working environment, the semi-transparent solid stick thing 2 of that section of printing opacity of top formation optically focused sunshine import is pyroceram rod preferably.
For effectively reducing the temperature at each position of sensor, improve its job stability, connecting pipe 3 outsides are also provided with heat radiator 6.
In addition, between the semi-transparent solid stick thing 5 of that section of printing opacity of light sensor and light sensor 4, be also provided with optical lens or color filter or both connecting, regulate and improve operating accuracy and the optical frequency working range of sensor.
Beneficial effect: by two sections of above semi-transparent solid stick things of printing opacity of separating are set, can effectively completely cut off the damage of heat conduction to light activated element, simultaneously with the semi-transparent solid stick thing of printing opacity together with, effective the decay light intensity of arrival light activated element; Flange-cooled connecting pipe, can be connected and fixed the semi-transparent solid stick thing of the printing opacity of segmentation, and the heat energy dissipation that can glass be absorbed by its surperficial heat radiator again, in environment, effectively reduces the temperature at each position of sensor.Adopt such design proposal, can change high-temperature stability and the light intensity absorption characteristic of sensor by changing the material behavior of the semi-transparent solid stick thing of printing opacity, control light intensity, the temperature working range of sensor.This programme can also increase optical lens and color filter at photoelectric sensor position, regulates and improve operating accuracy and the optics operating frequency range of sensor.

Embodiment
Below in conjunction with accompanying drawing, further describe the present invention.
Referring to Fig. 1 and Fig. 2, Salar light-gathering dish disclosed by the invention comprises the semi-transparent solid stick thing of printing opacity, connecting pipe 3 and light sensor 4 with tracking transducer, the semi-transparent solid stick thing of printing opacity can be divided into more than two sections, with connecting pipe 3 parcels, be connected, and be separated between at least one pair of adjacent semi-transparent solid stick thing of two sections of printing opacities.As seen in Figure 2, with two sections of semi-transparent solid stick things of printing opacity as an example, the inner structure of sensor of the present invention is shown.In leaning on the semi-transparent solid stick thing of two sections of printing opacities of outermost, the top of one section of semi-transparent solid stick thing 2 of printing opacity forms optically focused sunshine import 1 and another section of semi-transparent solid stick thing 5 connection light sensors 4 of printing opacity.Top forms the semi-transparent solid stick thing 2 of that section of printing opacity of optically focused sunshine import and preferably selects pyroceram as material.By two sections of above semi-transparent solid stick things of printing opacity of separating are set, can effectively completely cut off the hot polymerization light solar facula high temperature conduction damage to light activated element, simultaneously with the semi-transparent solid stick thing of printing opacity together with, effective the decay light intensity of high power sunshine arrival light activated element.
Further, as Fig. 1,2,3 findings, in connecting pipe 3 outsides, be also provided with heat radiator 6.Adopt flange-cooled connecting pipe, except the semi-transparent solid stick thing of the printing opacity of segmentation can being connected and fixed, the heat energy dissipation that can also glass be absorbed by its surperficial heat radiator, in environment, effectively reduces the temperature at each position of sensor.
Referring to Fig. 4 and Fig. 5, show the installation diagram of sensor of the present invention.Installation of sensors is on the hot spot of optically focused dish, receiver is collected by the receiver mouth of spot center the sunshine focusing on and is carried out work, sensor location is in receiver mouth surrounding, and the sunshine of focusing enters the sunshine import 1 on pyroceram rod 2 tops by the aperture of installation site.Light arrives sensor 4 by the gap between glass bar 2, glass bar 2 and glass bar 5 and glass bar 5, and sensor 4 connection detection circuit, realize and detecting.
