Support bearing for groove type heat collector and photothermal power generation system including support bearing

Abstract

The invention relates to a support bearing for a groove type heat collector and a photothermal power generation system including the support bearing. The support bearing comprises a bearing shell, a bearing base and a semicircular ball bearing, a bearing cover mounted at the upper end of the semicircular ball bearing through a bearing cover fixed bolt, a lifting plate, multiple spring stand columns, a sealing ring mounted on the outer side of the lifting plate and tightly matched with the bearing shell, a height adjusting plate, a double-wedge adjusting plate and a height adjusting screw rod, wherein the double-wedge adjusting plate includes a wedge adjusting block upper plate and a wedge adjusting block lower plate, which are fixed by a wedge adjusting block fixed bolt to form the double-wedge adjusting plate; the upper end surface of the wedge adjusting block upper plate is contacted with a groove type wedge structure on the lower end surface of the height adjusting plate; and the lower end surface of the wedge adjusting block lower plate is contacted with a groove type wedge structure formed on the inner surface of the bearing shell.

Description

technical field [0001] The invention relates to the field of photothermal power generation, in particular to a support bearing for a trough collector and a photothermal power generation system including the bearing Background technique [0002] The energy supply in the world today is tense, and the one-time fossil energy is facing the depletion of supply. The world energy crisis occurs from time to time, and pollutes the environment, emits a large amount of carbon dioxide gas, aggravates the greenhouse effect, leads to climate warming, and extreme weather continues to occur. A series of insurmountable environmental problems. Finding a clean, reliable, long-lasting new energy to replace disposable energy has become the most urgent issue of sustainable development in the world today. As a clean, environmentally friendly, inexhaustible and inexhaustible new energy source, solar energy is the most ideal, longest and most reliable alternative energy source in the future. [000...

AI Technical Summary

Problems solved by technology

[0005] Due to the long circuit and many fulcrums, in order to ensure the concentration accuracy of the collector bracket, it is required that the bracket must be guaranteed during the process of processing and production, the process of unit installation, the process of circuit installation, and the process of installation and adjustment of supporting columns Higher precision requirements; however, the support bearing design of the prior art makes the gap (margin) between the support bearing and the support shaft very small, making it difficult to achieve the above precision requirements during installation

In addition, during the long-term operation of the circuit, the support column also has irregular settlement of the foundation, and the change is slow, which is not easy to monitor. This makes the central axis of the collector support and the circuit deflect during the operation process, which in turn causes the swinging axis to drive The column moves together (because the gap between the support bearing and the support shaft is very small, almost close to the rigid connection), the settlement speed of the column foundation is accelerated, which directly leads to a decrease in focusing accuracy, a decrease in thermal efficiency, and even damage to the loop support
