Description

Movable photovoltaic bracket

Technical Field

The utility model belongs to the technical field of solar photovoltaic, and relates to a movable photovoltaic bracket.

Background

At present, new energy power generation projects are gradually developed towards the field intensification direction, in the new energy power generation projects, the occupied area of fields such as a fan platform, a booster station approach road and the like is large, and the fields have traffic demands but have lower use frequency, so that the field utilization rate is lower. Photovoltaic power generation is a mature technology in the current new energy power generation mode, and a photovoltaic support commonly used at present cannot move after installation is completed, so that a fixed photovoltaic support structure is difficult to apply to such a scene. The movable photovoltaic support studied at home and abroad needs to be poured into the foundation guide groove, the foundation engineering quantity is large, the photovoltaic support can only move directionally, and the application scene is limited.

However, no study of the freely movable photovoltaic support was found through the search of the published literature.

Disclosure of Invention

The utility model aims to provide a movable photovoltaic bracket so as to achieve the purpose of freely moving the photovoltaic bracket.

The utility model relates to a movable photovoltaic bracket which is arranged below a photovoltaic assembly and is characterized by comprising purlines, a cross beam, a front diagonal brace, a rear diagonal brace, a front upright post, a rear upright post, a steel plate and rollers: a plurality of sandal strips are transversely arranged below the photovoltaic module, and a plurality of cross beams are longitudinally arranged below the sandal strips; the middle part of the same cross beam is provided with a front upright post and a rear upright post in a downward inclined mode, steel plates are horizontally arranged at the bottoms of the front upright post and the rear upright post, and rollers are arranged at the bottoms of the steel plates; the front inclined strut and the rear inclined strut are respectively arranged on the front side and the rear side below the same cross beam, the lower end of the front inclined strut is connected with the middle of the front upright post, and the lower end of the rear inclined strut is connected with the middle of the rear upright post.

The anti-overturning capability is enhanced through the inclined arrangement of the front upright post and the rear upright post; the front upright post and the rear upright post are horizontally provided with steel plates, the bottoms of the steel plates are provided with pulleys, the steel plates and the pulleys are directly arranged on the ground, the downward load generated by wind pressure is transmitted to a natural foundation by the steel plates at the bottoms, the downward load is dispersed by the steel plates, and the surface soil body load is reduced.

Specifically, front upright posts or rear upright posts under different cross beams are connected through longitudinal horizontal supports, and the front upright posts and the rear upright posts under the same cross beam are connected through transverse horizontal supports. By arranging the longitudinal horizontal support and the transverse horizontal support, the stability of the bracket is further enhanced.

Concrete foundations are pre-buried under the ground of the field, and an anchor pulling base is arranged at the top of each concrete foundation; through holes are preset in the middle parts of the front upright post and the rear upright post, steel wire ropes penetrate into the anchor pulling base and the through holes, and the steel wire ropes are locked through steel wire rope clamps. The bracket is connected with the concrete foundation through a steel wire rope, and horizontal load and upward pulling load generated by wind pressure are transmitted to the lower foundation through the steel wire rope; at the moment, the anti-pulling force of the concrete foundation effectively ensures the anti-overturning of the upper structure; in addition, the support is connected with the concrete foundation only through the steel wire rope, and the support can freely move through the idler wheels only by unlocking the steel wire rope clamp when moving.

Optimally, the concrete foundation is positioned at the left side and the right side of the movable photovoltaic bracket, and is positioned at the middle part of the connecting line of the lower ends of the front upright post and the rear upright post. The position of the concrete foundation can not influence the transverse movement of the bracket, and the stress is more reasonable.

According to the movable photovoltaic bracket provided by the utility model, the connection mode between the bracket and the foundation is simplified, so that the bracket can be conveniently detached before moving; the photovoltaic bracket can freely move by arranging the roller; through the inclined arrangement of the upright posts, the anti-overturning capability of the foundation is ensured; the stress of the substrate is reduced through the arrangement of the steel plate, so that the photovoltaic bracket can be directly placed on the ground; the support is connected with the ground surface through the steel wire rope, so that the stability of the upper structure is ensured. The support is simple and convenient in construction process, and labor and effort are saved in the moving process.
