Problems solved by technology

[0002] At present, it is more common to use trough heat collectors in solar power generation, and their heat collectors have more or less defects. Most of the devices place the heat collector tube in the middle of the reflector, and track the sun synchronously with the reflector. , this will bring a lot of trouble to the installation of the water inlet and outlet pipes of the heat collector, and will cause water and air leakage. Besides, the integration efficiency is not high and the sunlight cannot be fully utilized.

Embodiment Construction

[0009] As can be clearly seen from the accompanying drawings, its implementation is very simple. When the sun came out in the morning, the photoelectric tracker (13) was just facing the sunlight, and the focal point of the semicircular reflector (4) was directly connected to the heat collector in the vacuum. On the back side of (5), the front and back sides of the vacuum straight-through heat collecting tube (5) are all irradiated by sunlight, increasing the sunlight irradiation area. When the sunlight deviates, the photoelectric tracker (13) will issue instructions to allow the deceleration electric (10) to turn left or right, and the semicircular reflector (4) will always be aimed at the sun, prolonging the heat collection time. In this way, the face of the semicircular reflector (4) in the morning is facing east, and automatically tracks westward in the afternoon. When the sun comes out in the next morning, the photoelectric tracker will automatically track the focal point o...

Abstract

Disclosed is an all-direction reflecting groove-type solar heat collection device. A straight-through type evacuated collector tube is fixed on a triangular support which can be fixed to the ground. A circular rail where a semicircular reflecting plate can move by 360 degrees is installed in the middle of the fixed triangular support. Inner-circle movement rails are installed at the two ends of the circular rail. Racks installed outside the inner-circle movement rails are meshed with transmission gears of a gear motor and can rotate left and right under driving of the gear motor. Each inner-circle movement rail is further provided with a photoelectric tracer and a photocell panel, wherein the photoelectric tracer is used for tracing sunlight. When the sunlight deviates, the photoelectric tracers can send out an instruction to make the gear reducer rotate to the left or to the right so that the gear reducer can be aligned with the sun directly, a focus point on the reflecting plate is also made to face towards the back side of the evacuated collector tube, the irradiation area of the sunlight is enlarged, and heat collection time is also prolonged.

Description

technical field [0001] The invention relates to a natural energy solar heat collection device, in particular to a medium-high temperature omnidirectional reflection trough solar heat collection device which can be used for power generation and industrial and mining enterprise steam. Background technique [0002] At present, it is more common to use trough heat collectors in solar power generation. Their heat collectors have more or less defects. Most of the devices place the heat collector tubes in the middle of the reflectors and track the sun synchronously with the reflectors. , This will bring a lot of trouble to the installation of the water inlet and outlet pipes of the heat collecting tubes, and water leakage and air leakage will occur. Besides, the integration efficiency is not high and the sunlight cannot be fully utilized. Contents of the invention [0003] In order to solve the above problems, the present invention proposes an all-round reflective trough solar he...
