Description

Technical Field

[0001] The invention relates to a photovoltaic power generation device, in particular to a photovoltaic power generation device with a flexible bracket. Background Art

[0002] Photovoltaic power generation device is a green and environmentally friendly power generation device that converts solar radiation energy into electrical energy. The photovoltaic components that perform energy conversion are installed on photovoltaic brackets. Photovoltaic brackets are usually installed on the ground. However, for places such as tidal flats, fish ponds, and complex mountainous areas, conventional photovoltaic brackets are difficult to install. The flexible photovoltaic bracket composed of photovoltaic components installed with steel cables is erected in the air, which can effectively and fully utilize various types of space, reduce the occupation of land resources, and has good development prospects.

[0003] In a flexible photovoltaic bracket that uses steel cables to install photovoltaic modules, both ends of the steel cables are fixedly connected to the steel frame columns, and the steel cable tensioning device is used to tension and tighten the cables between the two steel frame columns. In this state, the top of the steel frame column will be subject to a large bending moment. For this reason, an oblique tensioning structure must be set on the outside of the steel frame column or a rigid oblique support must be set on the inside of the steel frame column to ensure the overall rigidity of the flexible bracket. The steel frame column of such a structure itself needs to have sufficient rigidity between the steel cable connection point and the oblique support (tensioning) connection point, otherwise it is difficult to ensure the support of the steel cable; on the other hand, the steel cable will produce stress relaxation when it is in a tensile state, and the tension state will change due to the thermal expansion and contraction of the steel cable material, causing the position of the photovoltaic module on it to change. When the steel cable is relaxed, the photovoltaic module will also produce a large displacement and shaking under the action of wind, which will inevitably have a large impact on the high-efficiency power generation of the photovoltaic module.

[0004] In a flexible photovoltaic support, the photovoltaic module and the two steel cables usually need to be fixedly connected at four points, and each point usually requires more than one connecting bolt to fix the photovoltaic module and the steel cable. This is very inconvenient for the connection between the photovoltaic module and the steel cable in the air, which is time-consuming and labor-intensive, and the installation and construction efficiency is very low. Summary of the invention

[0005] In view of the above-mentioned deficiencies in the prior art, the technical problem to be solved by the present invention is to provide a flexible bracket photovoltaic power generation device, which can not only maintain the stability of the taut state of the steel cable, and has a simple bracket structure and good rigidity, but also ensures easy installation between the photovoltaic module and the steel cable, thereby improving the installation efficiency of the photovoltaic module.

[0006] In order to solve the above technical problems, a flexible bracket photovoltaic power generation device of the present invention includes a photovoltaic module and a steel cable for supporting the photovoltaic module, wherein both ends of the steel cable are fixedly connected to the foundation, and two steel cable pillars are fixedly connected to the foundation corresponding to each steel cable, and the steel cable pillar includes a pillar fixing part fixedly connected to the foundation and a pillar movable part movably connected to the pillar fixing part, a tension spring is provided between the pillar movable part and the pillar fixed part, a steel cable support wheel is rotatably supported at the top of the pillar movable part, the steel cable is embedded in the wheel groove of the steel cable support wheel, the steel cable pillar is inclined, and the axis of the steel cable pillar is located at the horizontal section of the steel cable between the two steel cable pillars and the inclined section of the steel cable outside the steel cable pillar. A steel cable tensioner is provided on the inclined section of the steel cable on the bisector of the angle between the inclined sections; the photovoltaic module is installed on the horizontal sections of the front and rear steel cables through a module bracket, and the module bracket includes a bracket body, and two grooves are provided on the bracket body, the spacing between the two grooves corresponds to the spacing between the two steel cables, the width of the grooves corresponds to the diameter of the steel cables, and the depth of the grooves is less than the diameter of the steel cables. A fixed clamp block and a movable clamp block are respectively provided at both ends of the bracket body, and the movable clamp block is movably connected to the bracket body along the length direction of the component bracket, and a clamping spring is provided between the movable clamp block and the bracket body, and the fixed clamp block and the movable clamp block are respectively clamped with the component frames on the two opposite sides of the photovoltaic module.

[0007] In the above structure, since the two ends of the steel cable are fixedly connected to the foundation, two steel cable pillars are fixedly connected to the foundation corresponding to each steel cable, and the steel cable pillar includes a pillar fixing part fixedly connected to the foundation and a pillar movable part movably connected to the pillar fixing part, a tension spring is provided between the pillar movable part and the pillar fixing part, and a steel cable support wheel is rotatably supported at the top of the pillar movable part, and the steel cable is embedded in the wheel groove of the steel cable support wheel. Then, the steel cable with both ends fixedly connected to the foundation forms a steel cable horizontal section between the two steel cable pillars and a steel cable inclined section outside the steel cable pillar under the support of the two steel cable pillars. The steel cable horizontal section is used to install photovoltaic modules. When the steel cable in a tensile state may produce stress relaxation or when the ambient temperature changes and causes the steel cable to expand and contract and change the tension state, the steel cable tension The tension of the steel cable will change, and at this moment, the force of the tension spring arranged between the fixed part of the pillar and the movable part of the pillar will change accordingly, causing the movable part of the pillar to produce axial displacement relative to the fixed part of the pillar. When the steel cable produces stress relaxation or elongation due to heat, the tension of the steel cable will decrease, and the tension spring will push the movable part of the pillar to extend outward and re-tighten the steel cable through the steel cable support wheel. On the contrary, when the steel cable becomes shorter due to cold, the tension of the steel cable will increase, and the tension spring will be compressed through the steel cable support wheel and the movable part of the pillar, causing the movable part of the pillar to retract inward, thereby reducing the tension of the steel cable. In this way, the tension of the steel cable will be maintained at a certain level, and the tension degree of the steel cable will remain basically unchanged, thereby maintaining the stability of the tension state of the steel cable, and the position state of the photovoltaic module will also remain unchanged, thereby ensuring the high-efficiency power generation of the photovoltaic module.

[0008] Because the steel cable support is inclined, the axis of the steel cable support is located on the bisector of the angle between the horizontal section of the steel cable between the two steel cable supports and the inclined section of the steel cable on the outside of the steel cable support. The bisector of the angle between the horizontal section of the steel cable and the inclined section of the steel cable on the outside of the steel cable support is also the line of action of the resultant force generated by the horizontal tension of the horizontal section of the steel cable and the oblique tension of the inclined section of the steel cable. The axis of the steel cable support is located on the bisector so that the force acting on the steel cable support can act on the axis of the steel cable support. Theoretically, the support fixed part and the support movable part of the steel cable support will not be subjected to radial force, thereby ensuring that the movable part of the support can be easily movably connected relative to the support fixed part, and also ensuring the stability of the steel cable support. The entire flexible bracket will have good rigidity, and the steel cable support does not need to have a connection structure with components such as the steel cable and oblique support (tensioning). The structure of the entire flexible bracket is very simple.

[0009] Also, since a cable tensioner is provided on the inclined section of the cable, the cable tensioning can be conveniently realized on the ground, avoiding the inconvenience of the conventional cable having both ends fixed on the cable supports requiring tensioning operation at high altitude, and facilitating the installation of the flexible bracket.

[0010] Furthermore, since the photovoltaic component is installed on the horizontal sections of the front and rear steel cables through a component bracket, the component bracket includes a bracket body, and two grooves are provided on the bracket body. The spacing between the two grooves corresponds to the spacing between the two steel cables, the width of the groove corresponds to the diameter of the steel cable, and the depth of the groove is smaller than the diameter of the steel cable. The bracket body and the two steel cables are connected through the two grooves, and the steel cables are embedded in the grooves and protrude from the bracket body because the depth of the grooves is smaller than the diameter of the steel cable. When the photovoltaic component is connected to the bracket body, the upper surface of the bracket body with the groove will fit with the lower surface of the frame of the photovoltaic component, and the steel cable will be pressed between the bracket body and the photovoltaic component, so that the photovoltaic component is connected to the steel cable.

[0011] The movable block is connected to the bracket body in a movable manner along the length direction of the component bracket, and a clamping spring is provided between the movable block and the bracket body. The fixed block and the movable block are respectively clamped with the component frames at two opposite sides of the photovoltaic component. The bracket body and the photovoltaic component are connected through the fixed block and the movable block. The setting of the movable block can ensure the quick and convenient installation and connection process. During the installation process, the fixed block can be first plugged and connected with a component frame of the photovoltaic component, and then the movable block can be pushed backward to overcome the elastic force of the clamping spring so that the movable block can enter a position where it can be clamped with the component frame. After the movable block is released, the movable block automatically moves forward under the action of the clamping spring and is plugged and connected with the component frame, and maintains the clamping state under the action of the elastic force. In this way, the photovoltaic component is fixedly connected to the steel cable, and there is no need to use bolts to tighten during the installation and connection process of the photovoltaic component, which is quick, convenient and efficient.
