Problems solved by technology

The development and utilization of solar energy is of strategic significance for the sustainable development of human beings and the creation of green mountains and clear water ecological environment; the use of solar energy can only play a major role in large-scale conversion into electrical energy; there are two ways to convert solar energy into electrical energy: one is photovoltaic power generation , one is photothermal power generation; photovoltaic power generation is the current formed by the quantum excitation of certain bands of solar radiation in the P-N junction of crystalline silicon cells. 14%; photovoltaic power generation technology is relatively mature, and its application is relatively common, but usually the power is not large; solar thermal power generation is the utilization of the average calorific value of solar radiation, and tower or parabolic trough concentrated power generation is commonly used; due to weak solar radiation, The average solar radiation intensity on the ground is 800-900W per square meter. Therefore, no matter what form of solar power generation is used, it needs to occupy a large amount of land area; cultivated land and farmland cannot be occupied, and the cost of mountain leveling is high. Uninhabited areas such as the Gobi Desert To build solar power stations in some places, roads and transmission lines need to be built, and the cost is also high
Expressways occupy a large area and have convenient transportation. By the end of 2016, the mileage of expressways in my country will reach 130,000 kilometers. Calculated with 4 lanes and a width of 3.5 meters per lane, the space area per kilometer is 14,000 square meters. The existing lanes in the country The area is 1.82 billion square meters; it has been reported on the Internet that American engineers have invented and designed to lay solar panels on the road surface of the expressway, and obtained venture capital funding; in order to save land resources, Ou Yinglei once published in "Guangdong Science and Technology" (No. 15, 2012, 218 -219 pages) puts forward "the idea of ​​using the expressway to realize solar photovoltaic power generation", that is, to use the road surface of the expressway to bury the solar panel, and use special optical materials to pave the road surface of the expressway, so as to realize the solar photovoltaic power generation of the expressway Power stations; however, laying solar panels on the road surface of the highway requires a transparent cover layer that can withstand the heavy load of the car. This is a problem. Production wastes a lot of other resources, so the technology of laying solar panels on highway roads is immature

Abstract

The invention discloses a power generation scheme of building a photovoltaic cell panel above an expressway. The scheme is composed of a photovoltaic cell panel assembly, a photovoltaic cell panel bracket, and an inverter. The scheme is characterized in that the photovoltaic cell panel assembly is facing south, and an inclination of the photovoltaic cell panel assembly is equal to local latitude [phi], and the photovoltaic cell panel assembly is installed on the photovoltaic cell panel bracket above an expressway. The photovoltaic cell panel bracket is formed by bracket columns, a beam, a plane grid frame, a triangular support, a pressure plate and fasteners, and has two design methods of a crossing bracket and a cantilever bracket. In the crossing bracket, the bracket columns are arrangedon two sides of a one-way lane in a separated manner, and the beam and the plane grid frame cross the lane. In the cantilever bracket, the bracket columns are in two rows and stand on one side of a roadside, and a cantilever beam extends above the lane. An installation method includes that the beam is built on the bracket columns, the plane grid frame is fixedly built on the beam, the triangularsupport is mounted on the plane grid frame, and the photovoltaic cell panel assembly is fixedly arranged on the triangular support.
