Description
Technical Field
The invention relates to a solar photovoltaic bracket, in particular to a method and a device for maintaining and replacing a photovoltaic bracket component.
Background
When solar photovoltaic, especially a large-area solar photovoltaic array or photovoltaic system is installed on the ground or on the water surface, the movement of the sun needs to be tracked in real time, and the direction of the photovoltaic module (for example, the movement from east to west) is adjusted, so that the sunlight directly irradiates to the light receiving plane of the photovoltaic panel, and the photovoltaic power generation amount is improved. Fig. 1 and 2 show a prior art tracking photovoltaic rack, in which a plurality of photovoltaic spindles 21 are arranged, for example, in the east-west direction, and each photovoltaic spindle 21 is provided with a group of photovoltaic modules 22, for example, in the north-south direction. The photovoltaic shaft 21 is mounted on a base (not shown) by means of a column 20, wherein the top end of the column 20 is provided with a shaft bearing 28, and the shaft 21 is rotatably sleeved in the bearing 28. In addition, in some tracking type photovoltaic supports, a tracking swing arm 23 is further disposed on the photovoltaic main shaft 21, one end of the tracking swing arm 23 is fixed to the photovoltaic main shaft 21, for example, by a hoop 26, and the other end is movably connected to a tracking push rod 24. When a tracking driver drives the tracking push rod 24 to reciprocate along the east-west direction, the tracking push rod 24 can drive the tracking swing arm 23 to swing along the east-west direction, so as to drive the photovoltaic main shaft 21 to rotate along the east-west direction, and thus drive the photovoltaic module 22 to track the sun along the east-west direction.
However, the photovoltaic support member, especially the spindle bearing 28 or the swing arm 23 mounted on the photovoltaic spindle 21 for supporting the spindle to rotate, needs to be maintained intensively and replaced if necessary due to long-term operation and exposure to sunlight and rain, which may cause damage over time. For photovoltaic supports with a short height, there is no significant operational difficulty in maintaining or replacing such support components. However, when the photovoltaic support is installed on uneven mountainous regions or under the scenes that crops and the like are left below the photovoltaic support, a part of the support can be erected higher. In this case, it is necessary to use a large-sized mechanical device such as a crane to lift the photovoltaic main shaft from the column or to remove the support member after the photovoltaic support is detached, which is not only complicated in operation but also long in construction period and high in cost. Accordingly, it is desirable to provide a compact and efficient method and apparatus for photovoltaic rack component maintenance and replacement.

Referring to fig. 3, the photovoltaic support includes a column 30 disposed on a base (not shown), and a photovoltaic mast 31 mounted on the column, which can carry a photovoltaic assembly 32. The top end of the upright column 30 is provided with a support part such as a main shaft bearing 38, the photovoltaic main shaft 31 is sleeved in the main shaft bearing 38 and can rotate under the driving of a driving device including a tracking push rod and a swing arm so as to enable the photovoltaic module 32 loaded on the photovoltaic main shaft to track the operation of the sun in real time. The bearing 38 is, for example, a polymer bearing, and preferably includes, for example, upper and lower portions, and the upper and lower portions of the bearing 38 can be closed or opened when the main shaft 31 is mounted on the column 30 or lifted from the column 30.
The photovoltaic rack part maintenance and exchange apparatus according to the present invention includes a push rod 34, a spindle support 35 installed at the top end of a telescopic bar 341 of the push rod 34, and a push rod base 36 for installing the push rod 34 in parallel to the side of the column 30.
