A kind of attachment means for solar photovoltaic generation system

Technical field

This utility model belongs to solar energy power generating field, and more particularly, to a kind of solar photovoltaic generation system is used for Attachment means.

Background technology

In order to absorb solar energy to large extent, general solar photovoltaic generation system is all arranged on of a relatively high sky In, first ground is accomplished fluently on ground according to layout drawing during installation, then the mounting bracket on ground, on the top of support drive is set up The main shaft that solar panel is rotated in east-west direction, by the multiple main shafts of power source drive.But the deviation due to measurement, , often there is range error, i.e. main shaft between adjacent main shaft in the various influence factors that physical features changes and work progress is produced Length and support between spacing exist and also there is larger gap between the joint face of certain error, main shaft and main shaft, Connection cannot be realized.Furthermore, the gap between main shaft and main shaft is also different, and a fixed attachment means cannot also meet Connection between each main shaft.

In order to realize the connection between main shaft, connecting shaft is generally connected between adjacent main shaft, connecting shaft is directly erected at support Top, frictional force is larger between connecting shaft and support, and the loss of power source is larger, and connecting shaft is rotated and is affected, and connecting shaft Service life it is shorter.

Utility model content

In order to overcome the deficiencies in the prior art, this utility model to provide and there is spacing between a kind of permission main shaft and connecting shaft, And adapt to different spacing, the little attachment means for solar photovoltaic generation system of connecting shaft rotation friction.

This utility model solves the technical scheme that its technical problem adopted：One kind is used for solar photovoltaic generation system Attachment means, the solar energy photovoltaic system includes that the harvester for gathering sunlight is flexibly connected with harvester Main shaft and the connecting shaft that is connected with main shaft, the connecting shaft is connected by an anti-slip structure with spindle mobility.Corresponding to connecting shaft Support ground base location is relatively fixed, and when there is a certain distance between main shaft and the joint face of connecting shaft, anti-slip structure sets Putting can make up the distance between main shaft and connecting shaft.

Further, the connecting shaft is provided with connecting seat, is provided between the connecting seat and connecting shaft for reducing frictional force Transitioning component.When connecting shaft is placed directly within support, the frictional force between connecting shaft and support is larger, the power transmission of power source Loss is larger, affects the rotation of main shaft, and the service life of connecting shaft is short.

Further, the anti-slip structure includes the first connector that can be connected with connecting shaft and can be connected with main shaft the Two connectors, one end of the main shaft and the second connector clearance fit, the main shaft can be in preset range along the second connection Body moves back and forth.

Further, second connector include chute and can be movable back and forth in chute connector, the connection Part is connected with main shaft.The setting of chute causes the attachment structure to be adapted to different spacing ranges, and the setting of chute is also limited The preset range that main shaft moves back and forth, the i.e. length of chute determines the displacement of main shaft.

Further, the connector include nuts and bolt, described bolt one end be each passed through after main shaft and chute with Nut thread coordinates.

Further, the main shaft is provided with locating part, and the locating part is detachably connected with the second connector.Locating part Arrange and cause the connection between main shaft and the second connector even closer firm, it is to avoid Second support occurs significantly to tumble.

Further, the U-shaped structure of the locating part.The periphery of Second support is set in by the opening of locating part, It is easy to assembly, and the outer wall cooperation of the inwall of locating part and main shaft, both connect even closer stable.

Further, the transitioning component includes bearing and bearing shell.Bearing and bearing shell are reduced between connecting shaft and support Frictional resistance so that main axis are more smooth, extends the service life of main shaft and electricity generation system.

Further, the connecting shaft is between adjacent main shaft.

Further, the connecting shaft is located at the end of main shaft.

The beneficial effects of the utility model are：One power source drives multiple main shaft synchronous axial systems, so as to reduce power The setting quantity in source, is connected between main shaft by attachment means, reduces the frictional resistance of rotation, extends the use longevity of system Life, anti-slip architecture is simple, is completely embedded firm, is adapted to spacing ranges different between main shaft and connecting shaft.
