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 the solar 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 orientation (such as the movement from east to west) of the photovoltaic module is adjusted so that sunlight is directly irradiated to the light receiving plane of the photovoltaic panel, and the photovoltaic power generation capacity is improved. Fig. 1 and 2 show a prior art tracking photovoltaic support, wherein the photovoltaic support is provided with a plurality of photovoltaic spindles 21, for example in the east-west direction, and each photovoltaic spindle 21 is provided with a set of photovoltaic modules 22, for example in the north-south direction. The photovoltaic spindle 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 spindle bearing 28, the spindle 21 being rotatably journalled in the bearing 28. In addition, in some tracking type photovoltaic supports, a tracking swing arm 23 is further provided on the photovoltaic main shaft 21, and 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 actuator, for example, drives the tracking pushrod 24 to reciprocate in the east-west direction, the tracking pushrod 24 may oscillate the tracking swing arm 23 in the east-west direction, thereby rotating the photovoltaic main shaft 21 in the east-west direction and thereby driving the photovoltaic module 22 to track the sun in the east-west direction, for example.
However, the photovoltaic bracket member, particularly the spindle bearing 28 or even the swing arm 23 or the like mounted on the photovoltaic spindle 21 for supporting the spindle to rotate, requires intensive maintenance due to long-term operation and exposure to sun and rain and sun and rain, and may cause damage over time, and must be replaced if necessary. For photovoltaic modules of relatively low height, there is no great difficulty in operation in the maintenance or replacement of such module components. However, when the photovoltaic bracket is installed on a mountain with uneven height, or under the condition that crops and the like remain below the photovoltaic bracket, a part of the bracket is 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 photovoltaic bracket and then take out the bracket member, which is complicated in operation, long in construction period, and high in cost. It is therefore desirable to provide a compact and efficient method and apparatus for maintenance and replacement of photovoltaic bracket components.

Detailed Description
The following detailed description of the method and apparatus for maintenance and replacement of photovoltaic bracket components of the present invention will be made with reference to the accompanying drawings and examples, which are shown by way of illustration only and are intended to facilitate an understanding of the basic concepts of the present invention.
Fig. 3 is a schematic diagram illustrating a method and apparatus for maintenance and replacement of photovoltaic bracket components according to one embodiment of the present invention. Referring to fig. 3, the photovoltaic bracket includes a post 30 disposed on a base (not shown), and a photovoltaic spindle 31 mounted on the post, which may carry a photovoltaic module 32. The top end of the upright 30 is provided with a bracket component, such as a main shaft bearing 38, and the photovoltaic main shaft 31 is sleeved in the main shaft bearing 38 and can rotate under the drive of a driving device comprising a tracking push rod and a swing arm, so that the photovoltaic module 32 carried on the photovoltaic module can track the operation of the sun in real time. The bearing 38 is, for example, a polymer bearing, and preferably includes, for example, an upper portion and a lower portion, and the upper portion and the lower portion of the bearing 38 can be closed or opened when the main shaft 31 is mounted to the column 30 or lifted from the column 30.
The photovoltaic bracket component maintenance and replacement apparatus according to the present invention includes a push rod 34, a main shaft support 35 mounted on the top end of a telescopic rod 341 of the push rod 34, and a push rod base 36 for mounting the push rod 34 in parallel to the side of the column 30.
Fig. 4 is a schematic view showing the push rod shown in fig. 3 mounted on the upright, and fig. 5 is a schematic view showing the push rod shown in fig. 3 lifting the photovoltaic main shaft on the bracket. Referring to fig. 3-5 in combination, the bottom of the pushrod 34 is disposed above a pushrod base 36. The push rod base 36 is, for example, an L-shaped member, one side of which can be tightly attached to the side of the upright post 30, and two ends of which are provided with through holes, for example, fixed to the side of the upright post 30 by a U-shaped pipe clamp 361; the other side is perpendicular to the side of the upright 30 and serves as a platform 362 for supporting the push rod 34. Those skilled in the art will appreciate that the push rod 34 may be positioned, for example, by binding its shaft to the side of the post 30. The top end of the telescopic rod 341 of the push rod 34 is provided with a spindle support 35, for example, of U-shaped configuration, which opens upwards and allows the bottom of the spindle 31 to be inserted therein. The push rod 34 is shown as a hand push rod with self-locking function, for example, and the bottom input 342 is operable with a crank (not shown). Preferably, the push rod 34 is also an electric push rod and is driven by a motor.
According to the maintenance and replacement method of the photovoltaic bracket member of the present invention, for example, when the main shaft bearing 38 mounted on the top end of the column 30 requires maintenance or replacement, it can be operated according to the following steps:
A. the push rods 34 are mounted parallel to the sides of the upright 30, for example, a push rod mount 36 is mounted to the side of the upright 30, and the push rod mount 36 is secured to the upright 30 by a U-shaped tube clamp 361. The bottom of the push rod 34 is then positioned over the push rod base 36, positioning the push rod 34 with its telescoping rod toward the bottom of the spindle 31.
B. The spindle support 35 is installed at the top end of the telescopic rod 341 of the push rod 34, and it is constructed in a U-shape, for example, so that the bottom of the spindle 31 is inserted therein. Then, the upper and lower portions of the bearing 38 are separated;
C. the push rod is started to lift the photovoltaic main shaft 31 upwards from the top end of the upright post 30. If the push rod is a hand push rod, the input end of the push rod is rotated by a crank, the telescopic rod 341 of the push rod 34 is extended upward to push the main shaft 31 upward, and if the push rod is an electric push rod, the push rod is driven by a motor. Preferably, the push rods are arranged on the upright posts which erect the same main shaft, and all push rod linkage operation is controlled at the same time;
D. the spindle bearing 38 is removed from the top end of the post 30 and serviced or replaced;
E. reinstalling the maintained or replaced spindle bearing 38 on top of the post 30;
