Example Embodiment
[0030] Example 1
[0031] Such as figure 1 , Figure 4 , Figure 5 As shown, a first heat collecting tube 1 is provided at the focal line position of the first parabolic concentrating groove 2, an opening 19 is provided at the center of the first parabolic concentrating groove 2, and a second parabolic concentrating tube is provided at the opening 19 The groove 12 is provided with a second heat collecting tube 14 at the focal line of the second parabolic concentrating groove 12, and the sunlight radiating from the rear and side of the second parabolic concentrating groove 12 to the second heat collecting tube 14 is collected by the first The heat pipe 1 and the second parabolic concentrating groove 12 are all shielded, and the sunlight from the front and side front of the second parabolic concentrating groove 12 to the second heat collecting tube 14 is focused on the second heat collecting tube 14, from the first collector The sunlight directed to the second collector tube 14 in...
Example Embodiment
[0036] Example 2
[0037] Such as figure 1 , Figure 4 , Figure 5 As shown, on the basis of embodiment 1, the rotating device 5 is changed to a hollow turntable, the connection between the two ends of the rotating shaft 4 and the second bracket 10 is changed to sliding sleeve connection, and the second bracket 10 is changed to a fixed type at both ends. Yes, the bottom of the second bracket 10 is fixed on the foundation.
[0038] The first parabolic concentrating trough 2 is placed in an east-west direction and rotating in a north-south direction. There are 12 first parabolic concentrating troughs 2, and 4 of them are connected in series to form an array. A total of 3 rows form an array.
Example Embodiment
[0039] Example 3
[0040] Such as figure 2 , Figure 4 , Figure 5 As shown, on the basis of Example 1, the rotating device 5 and the pressure guiding tube 8 are changed to a separate type. The rotating device 5 is a solid turntable. A small hole is opened on the rotating shaft 4 and a guide is installed at the small hole. The pressure hose is connected with the hydraulic cylinder.
[0041] The two ends of the rotating shaft 4 are connected to the second bracket 10 in a manner of connecting through a bearing 6. The second bracket 10 has one end fixed and one end telescopic, and the bottom of the second bracket 10 is fixed on the foundation. A temperature compensation adjusting device (26) is installed on the hydraulic cylinder (9), and the temperature compensation adjusting device (26) is a manual hydraulic pump.
[0042] The first parabolic concentrating trough 2 is placed in the east-west direction and rotating in the north-south direction. There is only one first parabolic conc...
