Abstract

The utility model relates to a sunshine tracked solar energy heat collector which is composed of a solar energy collecting plate, a ball-shaped base, light catching transmitting signal devices, an editor, a shift mechanism controlling the shift of the solar energy collecting plate and a power pump which provides power for the shift mechanism, wherein the solar energy collecting plate is installed on the ball-shaped base; the lighting catching transmitting signal devices are installed at the four corners of the solar energy collecting plate; the shift mechanism is installed at the bottom of the four corners of the solar energy collecting plate and is connected with the solar energy collecting plate; the solar light irradiation vector quantity which is caught by the lighting catching transmitting signal devices is conveyed to the editor, the editor conveys the command signals to four follow-up amplifiers which are arranged on a telescopic oil cylinder, and the amplified command signals are conveyed to an electro-hydraulic follow-up valve to start the telescopic oil cylinder. The expansion and the contraction of the piston rod of the telescopic oil cylinder drive the solar energy collector to rotate; therefore, an optimal energy taking angle can be kept between the solar energy collector and the solar light irradiating angle. The structure of the utility model is simple, the sunshine tracked solar energy heat collector can be kept under the perpendicular incidence of the sunlight, and the heat-collecting efficiency is greatly improved.

Description

But the solar thermal collector of tracks sunlight

Technical field

The utility model belongs to a kind of solar energy equipment, but a kind of specifically solar thermal collector that utilizes the tracks sunlight of solar energy to greatest extent.

Technical background

When sun direct projection was on solar heat-collection plate, the solar heat that the thermal-arrest plate is collected was most effective.Because the sun is different at the irradiating angle of different time, so the solar thermal collector of existing fixed formula can only be accepted the sunlight direct projection in a certain period, the most of times in one day are then accepted the oblique fire of sunlight, have influenced the collecting efficiency of thermal-arrest plate.

Summary of the invention

But the technical problems to be solved in the utility model is to provide a kind of solar thermal collector that can make the solar heat-collection plate maintenance be subjected to the tracks sunlight of sun direct projection.

The technical scheme that the utility model solves the problems of the technologies described above is: a kind of solar thermal collector of following the tracks of the sun, it is characterized in that described heat collector by solar heat-collection plate, ball-type base, catch the gearshift of light signalling generator, editing machine, the displacement of control solar heat-collection plate and form for gearshift provides the kinetic pump of power; Solar heat-collection plate is installed on the ball-type base, and catching the light signalling generator has four, is installed in four jiaos of solar heat-collection plate respectively, and four gearshifts are installed in the bottom of four jiaos of solar thermal collectors and are connected with it; Power set provide power for four displacements; Respectively by transmission line with catch the light signalling generator and be connected; Gearshift is made up of the servo-actuated amplifier, servo, oil cylinder and the feedback potentiometer that are connected in series successively, and editing machine is connected with the servo-actuated amplifier by output line, and feedback potentiometer then feeds back to editing machine by the servo-actuated amplifier with execution command.

Described oil cylinder is the bi-directional push-pull oil cylinder, and the top of its piston rod is connected for four jiaos with solar energy; Feedback amplifier is installed in the bypass of the piston rod other end; Servo is made up of two electro hydraulic valves that are communicated with by oil pipe and electrically-controlled valve, and two electro hydraulic valves are connected with oil cylinder by oil pipe; Power set are made up of oil pump and fuel tank; Two electro hydraulic valves are communicated with fuel tank with oil pump and oil return oil pipe by input oil pipe respectively; Electrically-controlled valve also is communicated with fuel tank by oil return pipe.

The link of described oil cylinder piston bar and solar heat-collection plate is with a piston rod sleeve that shields.

Operation principle of the present utility model is: four jiaos of light signalling generators of catching that are provided with of solar thermal collector flow to editing machine with the solar irradiation vector that traps, editing machine is passed to command signal in the servo-actuated amplifier that disposes with four telescopic oil cylinders, the command signal of amplifying is sent into servo start telescopic oil cylinder, the piston rod of telescopic oil cylinder is flexible, rotate thereby drive heat collector, get the energy angle thereby solar thermal collector and solar light irradiation angle are remained on the best.

The feedback potentiometer that is provided with on the telescopic oil cylinder piston rod feeds back to editing machine with fill order, and formation network closed circuit is finished and caught the light following function.

The utility model is simple in structure, and solar energy heat collector is under the direct projection of sunlight all the time, has greatly improved collecting efficiency.Can be used for the solar water heater of multiple structure or the solar energy heat collector of warmer.
