Abstract

DC60 (13/09/54) Solar Thermal Power Generation System consists of two rust-proof metal support poles for mounting and supporting the solar collector unit. The solar collector unit comprises several parabolic trough solar receivers arranged parallel to each other along the length of the unit. These receivers concentrate sunlight by reflecting it off their curved surfaces towards a focal point according to the radius of curvature. Vacuum glass tubes are securely attached to each support arm along the length of the receiver, positioned at the focal point according to the radius of curvature. Heat transfer tubes are inserted along the length of the vacuum glass tubes. A sun-tracking control unit is mounted on one side of the support pole to automatically guide the solar collectors to a position perpendicular to the sun, maximizing solar intensity. The pole, a rust-proof metal structure, serves as a support and brace for the solar collector system. The solar collector system consists of several parabolic trough solar receivers arranged in a sequence along the length of the receiver. These receivers concentrate sunlight by reflecting it off their curved surfaces towards a focal point according to the radius of curvature. Vacuum glass tubes are securely attached to each support arm along the length of the receiver, positioned at the focal point according to the radius of curvature. Heat transfer tubes are inserted along the length of the vacuum glass tubes. A sun-tracking control unit is mounted on one side of the support pole to automatically guide the solar collectors to a position perpendicular to the sun, maximizing solar intensity.

Claims (2)

1. The solar thermal power generation unit consists of two rust-proofed metal support posts (1) that hold and support the solar collector (4). At the bottom of each support post (1) is mounted on a support base (2), at the top of which is a ball bearing (3) to support the rotation of the solar collector (4). A sun-tracking control unit (13) is mounted on one side of the support posts (1) to automatically control the solar collector (4) to move perpendicular to the sun to maximize solar intensity. The sun-tracking control unit (13) contains a prime mover motor (14) that powers at least one test gear (15) to drive a spindle (7) mounted in ball bearings (3) to move the solar collector (4). The prime mover motor (14) is externally controlled to regulate its speed and drive the motor. Rotating clockwise and counterclockwise to accurately follow the direction of the sun's movement from east to west, the solar receiver (4) consists of a number of parabolic trough solar receivers (5) laid parallel to each other along the length. The parabolic trough solar receivers (5) are made of stainless steel with a mirror-like sheen to concentrate sunlight by reflecting it off the parabolic surfaces towards a focal point along the radius of curvature of the parabolic trough solar receiver (5). On both sides, in the center of each parabolic trough solar receiver (5), are connected to side joints (6), and at the bottom, in the joints of each parabolic trough solar receiver (5), there is a reinforcing ridge (8). The side joints (6) are attached to the rotating shaft (7), which is fitted into a bearing (3). The support arm (9) is mounted at the top, in the joints of each parabolic trough solar receiver. Each parabolic trough (5) is used to support the vacuum tube (10). Specifically, the vacuum tube (10) is attached to each support arm (9) along the length of the parabolic trough solar receiver (5) by means of a fastening method (11). The vacuum tube (10) is positioned at the focal point according to the radius of curvature of the parabolic trough solar receiver (5) to receive the direct sunlight reflected from the parabolic trough solar receiver (5) and transfer heat to the heat transfer medium flowing inside the heat transfer medium tube (12), raising its temperature to a specified level. Along the length of the vacuum tube (10) are several clamps (16) and a stainless steel heat transfer medium tube (12) is inserted to allow the heat transfer medium to flow through. The heat transfer medium tube (12) is inserted along the length of the vacuum tube (10). 2. Solar thermal power generation system, according to claim 1, in which the solar thermal power generation system can be arranged in a line with each solar thermal power generation system installed in a line with each solar thermal power generation system connected by flexible tubing ((12) of each solar thermal power generation system (17).
