Description
Technical field
The utility model belongs to solar energy power generating field, more particularly, to the connection knot of solar photovoltaic generation system
Structure field, specifically a kind of transmission joint and solar photovoltaic generation system.
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, ground is first accomplished fluently on ground according to layout drawing during installation, then the mounting bracket on ground, drive is set up on the top of support
The main shaft that solar panel rotates in east-west direction, pass through the multiple main shafts of power source drive.But due to the deviation of measurement,
Physical features change and work progress caused by various influence factors, range error, i.e. main shaft often be present between adjacent main shaft
Length and support between spacing certain error be present, larger gap between main shaft and the joint face of main shaft also be present,
Connection can not be realized.Furthermore the gap between main shaft and main shaft is also different, a fixed attachment means can not 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 transmission loss of power source is larger, and connecting shaft is rotated and is affected, and connecting shaft
Service life it is shorter.
In view of the above-mentioned problems, Chinese patent 2016210252272《A kind of connection for solar photovoltaic generation system fills
Put》Disclose between a kind of permission main shaft and connecting shaft and spacing be present, and adapt to different spacing, the small company of connecting shaft rotation friction
Connection device, but under sleety weather, water is easily accessible the gap between connecting seat and connecting shaft, causes the life of connecting shaft internal part
Rust, still larger using the frictional force between rear connecting shaft and support for a long time, the power transmission loss of power source is larger, influences to lead
The rotation of axle, and the service life of connecting shaft is short.
