【detailed description】

An integrated structure of solar photovoltaic power generation and railway, as shown in Figures 1 to 9, includes a solar photovoltaic power generation part and a railway power receiving part, and the photovoltaic power generation part includes a plurality of solar photovoltaic modules 31 not in contact Arranged solar unit panels 3 and a plurality of fixed brackets 1; the railway power receiving part includes a railway track 2, a power grid line 4 located above the railway track 2, and erected on both sides of the railway track 2 to support the power grid line 4 catenary pillars 5, 6; all fixed brackets 1 are arranged at certain intervals along the railway track 2, and the fixed brackets include a pair of vertical columns 11, 12 installed on both sides of the railway track 2 and the pair of vertical columns 11 , 12 fixedly connected structural beams 13; the unit plate 3 is installed on the structural beams 13 on the fixed support 1 and tilted to one side, due to the influence of the angle of the sun's rays in winter and summer and in order to ensure that the sun is still at its weakest It can ensure a large amount of solar power generation. After the unit panel 3 is installed on the structural beam 13 of the fixed support 1, its slope is all towards the earth's equator (that is, the end far away from the equator is higher than the end close to the equator), which can ensure When the sun is far away from this latitude, the unit panel still has relatively large solar energy to ensure that power can be provided to the train to the greatest extent; the pair of vertical columns 11, 12 and the railway track 2 sides are used to install the catenary of the grid line 4 The distance between pillars 5 and 6 is greater than the standard safety distance, and the distance between the bottom surface of the structural beam 13 and the grid line 4 is greater than the standard safety distance, so that after the overall structure is installed, the normal operation of the train will not be affected. When the present invention is installed, the fixing bracket is first fixed at a safe distance from the catenary pillar, and then a plurality of solar photovoltaic modules 31 are arranged and fixed on the structural beam 13 on the fixing bracket to form a unit board 3 and make this The unit plate 3 is inclined to one side, and the slope of the entire unit plate 3 must face the direction of the equator according to the direction and direction of the track 2, so that after all the fixing brackets and all the unit plates are installed on the entire railway track, the unit can pass through The panel converts solar energy into electrical energy, and then transmits it to the train through the grid line, providing the power for the normal transportation of the train, thus forming an integrated structure of solar photovoltaic power generation and railway, making full use of a large amount of land along the railway to build photovoltaic power stations, energy saving and environmental protection At the same time, it also acts as the roof of the railway line to prevent the influence of dirt, rain, snow, fog and lightning on the grid line, thereby improving the safety of railway operation.

Now specifically illustrate the structure of the present invention, take the northern hemisphere as an example, as shown in Figures 1 to 8, no matter whether the railway track is east-west or north-south or east-west turns to the north-south direction, the unit plate installed on the adjacent fixed bracket The incline always faces south; as shown in Figure 6 to 8, when the railway track is in the east-west direction (usually with a reference of ±10 degrees north), after all the unit panels are installed, it looks like all the unit panels are in contact with each other from the side As shown in Figure 3 to 5, when the railway track runs north-south (usually ±10 degrees to the east as a reference), after all the unit panels are installed, each unit panel has Regularly arranged in waves above the track; it can be seen from the above that when the track changes from north-south to east-west, the fixed bracket rotates 90 degrees, and the unit plate also rotates 90 degrees, but the slope of the unit plate is always facing south. When the railway track turns, as shown in Figure 1, the track turns from south to east or from east to south. When the turning angle is less than 45 degrees, the orientation of the unit plates will be arranged in the east-west direction, but each The unit boards usually move a certain distance to the side of the turning direction, that is, from the top view, each unit board will be arranged in a ladder shape; when the turning angle is greater than 45 degrees, the unit boards will turn 90 degrees, and the The unit boards will be arranged in an east-west direction; similarly, the slope of the unit boards installed in the southern hemisphere faces north (as shown in Figure 2).

In the embodiment shown in Figures 4 and 8, the pair of vertical columns 11 and 12 of the fixed bracket 1 are fixedly installed on the ground obliquely to one side, and the distance between them gradually widens from the bottom to the top; this This structure can not only increase the solar power generation by increasing the installation area of the unit plate, but also be suitable for installation and fixation on the railway track on the viaduct; it can also be shown in Figure 9 that the vertical columns 11 and 12 of the fixed bracket are perpendicular to the ground.

Although the present invention has been described in detail with reference to the above embodiments, it will be apparent to those skilled in the art through this disclosure that the present invention can be modified without departing from the principle and spirit scope of the present invention defined by the claims. various changes or modifications. Therefore, the detailed description of the embodiments of the present disclosure is only for explanation, not for limiting the present invention, but the content of the claims defines the scope of protection.
