Detailed Description
In order to make the technical means, the creation characteristics, the achievement purposes and the effects of the invention easy to understand, the invention is further described with the specific embodiments.
The invention relates to a construction method of a flexible photovoltaic power station, in particular to a construction method of the flexible photovoltaic power station. And constructing and installing the flexible photovoltaic power station at suitable points such as mountainous regions or farmlands. The invention mainly aims to explain the construction of a mechanical mechanism part of a flexible photovoltaic power station.
The flexible photovoltaic power plant also has a support frame, however, the support frame is systematic and not a single support frame for a single photovoltaic panel. In addition, carry out flexible mounting through wire rope to the photovoltaic board, can improve the utilization ratio to the space.
The flexible photovoltaic power station comprises a supporting system, a cable system and a photovoltaic panel. The support system plays a role of a bracket and comprises upright posts, cross beams and anchor cables. The upright post is divided into a side post and a support post, and the side post is the post positioned at the edge of the whole support system as the name suggests. The lower extreme of stand is installed on the ground basis. The foundation base is a concrete foundation poured in advance. The crossbeam fixed mounting is on the top of stand, and the anchor rope draws fixedly to one side crossbeam and stand, makes whole braced system can stabilize. The cross beam is divided into an end beam and a support beam; as the name implies, an end beam is a cross beam located at an edge of the overall support system. The crossbeam is used for installing the cable, then installs photovoltaic board in the drawing.
The columns and beams are typically made of Q235 steel or Q345B steel.
The anchor cable is in the form of a guy cable, and a steel wire rope is generally used.
The cable system comprises a cable and a connecting installation piece. The guy cable is connected and arranged on the cross beam and is vertical to the cross beam. The fixing forms of the photovoltaic panel and the inhaul cable are divided into a transverse form and a longitudinal form;
above-mentioned anchor rope and cable and braced system are connected and are formed space grid structure, and the photovoltaic board is installed on space grid structure, and is specific with the direct fixed connection of cable.
At the stress concentration point, the forms of pressing blocks, anchoring by means of terrain and the like are adopted, the adhesive force of the net rack framework is increased, the wind prevention and wind defense effects are achieved, and the stability is increased.
The specific construction steps of the flexible photovoltaic power station are as follows,
1) Pouring a concrete foundation at the designed position; the distance between every two upright columns is 6-8 meters, so that the distance between the upright columns can be ensured on the concrete foundation base. The total span is controlled within 200 meters.
2) Fixing the upright post on the concrete foundation; in order to improve the stability, after the side column is fixed with the foundation, an anchor cable is used for fixing in a diagonal pulling mode. If necessary, a foundation made of concrete is also provided for the lower fixing end of the anchor line. In addition, because the stress on the side columns is large, the inclined pull rod can be arranged on the basis of the inclined pull anchor cable, as shown in fig. 1. The upper end of the diagonal draw bar is connected with the upper end of the side column, and then is pulled downwards in an inclined mode, and the lower end of the diagonal draw bar is fixedly connected with a foundation made of concrete. The anchor cables that draw to one side can set up two sets ofly, is located the both sides of side post respectively.
