Problems solved by technology

The current solar thermal collectors with multi-degree-of-freedom light tracking capability require two or more motors to work together or use a motor to cooperate with a clutch to work. The equipment is complex and not convenient enough. The elevation and azimuth of the sky where the sun is located, adjust the elevation and azimuth of the solar thermal collector in real time

Embodiment 1

[0034] Such as figure 1 and 2 As shown, a single-motor two-degree-of-freedom light-following solar thermal collector includes a base 1, a driving motor 1-1, a revolving disk 2, a first ratchet and pawl mechanism 3, a second ratchet and pawl mechanism 5, and a central shaft 6. Pitch transmission assembly, solar heat collector plate 4, light tracking detection module 10 and controller. The driving motor 1-1 is connected to the controller through a motor driver. The light intensity sensor in the light tracking detection module 10 is connected to the controller.

[0035]The epicyclic disk 2 is installed above the base 1, and forms a rotating pair with the base 1 through a thrust bearing, which is vertically arranged with a common axis. A first ratchet and pawl mechanism 3 is arranged between the turntable 2 and the base 1 so that the turntable 2 and the base 1 can only rotate in one direction. The vertically arranged central rotating shaft 6 and the base 1 form a revolving pai...

Embodiment 2

[0051] The difference between this embodiment and Embodiment 1 is that two one-way bearings are used to replace the first ratchet and pawl mechanism 3 and the second ratchet and pawl mechanism 5 respectively; thus, the forward and reverse rotation of the drive motor can be realized respectively to realize the solar thermal collector plate Adjustment of pitch angle and azimuth angle.

Embodiment 3

[0053] The difference between this embodiment and Embodiment 1 is that a speed reducer is added between the driving motor and the central rotating shaft to further improve the precision of light tracking.

Abstract

The invention discloses a single-motor two-degree-of-freedom light-following solar heat collector and a heat collecting method thereof. The solar power generation device includes a base, a revolving disk, a central rotating shaft, a pitch transmission assembly and a solar heat collecting plate. The epicyclic disc is installed on the base, and forms a unidirectional rotating pair with the base. The central rotating shaft and the epicyclic disc form a revolving pair that rotates in one direction. The rotation direction of the epicyclic disk relative to the base is opposite to the rotation direction of the epicyclic disk relative to the central shaft. The central shaft is driven to rotate by a drive motor. One side edge of the solar heat collecting plate is hinged with the turntable. The solar thermal collector plate is connected with the central rotating shaft through a pitch transmission assembly. The pitching transmission assembly converts the one-way rotation of the central shaft relative to the epicyclic disk into the reciprocating and flipping motion of the solar heat collecting plate. The invention realizes the adjustment of the azimuth angle and the elevation angle of the solar heat collecting plate by using the forward rotation and the reverse rotation of the driving motor respectively, so that the solar heat collecting plate always faces the sun.

Description

technical field [0001] The invention belongs to the technical field of solar heat collection, and in particular relates to a single-motor two-degree-of-freedom light-following solar heat collector and a heat collection method thereof. Background technique [0002] At different times of the day, the elevation and azimuth of the sun are different. If the position of the solar thermal collector is fixed, the solar radiation received by the solar thermal collector is limited, resulting in less heat collection efficiency of the solar thermal collector. This requires the solar thermal collector to have a light-following function, which can adjust the elevation angle and azimuth angle of the solar thermal collector according to the elevation angle and azimuth angle in the sky where the sun is located, so that the solar thermal collector is always facing the sun. The current solar thermal collectors with multi-degree-of-freedom light tracking capability require two or more motors t...
