<p>A concentrating-type solar heat collecting device and a heat collecting system. The heat collecting device comprises a light concentrating lens (1). The light concentrating lens (1) is mounted on a connecting frame (5). A supporting frame (6) is disposed on the periphery of the connecting frame (5). The supporting frame (6) is connected to a fixed frame (8) through a first rotary shaft (7) in the Y-axis direction, and can rotate about the first rotary shaft (7). The connecting frame (5) is connected to the supporting frame (6) through a second rotary shaft (3) in the X-axis direction, and can rotate about the second rotary shaft (3). The axis of the first rotary shaft (7) and the axis of the second rotary shaft (3) both run through the focus of the light concentrating lens (1). A heat collecting tube (4) is disposed below the light concentrating lens (1). The heat collecting tube (4) is provided with a heat collecting head (10). The center of the heat collecting head (10) is at the focus of the light concentrating lens (1). The heat collecting device of this structure can adjust the light receiving angle of the light concentrating lens (1), and is high in heat collecting efficiency, simple in structure, and convenient for adjustment.</p> |
