Description

Technical Field

[0001] The utility model relates to the technical field of photovoltaic systems, in particular to a suspension support structure, a photovoltaic tracking system and a photovoltaic system. Background Art

[0002] The multi-point rotary drive photovoltaic tracking system uses multiple driving points to drive the photovoltaic modules to rotate, and its stability performance is better than that of the tracking system with a single drive unit.

[0003] In a multi-point slewing drive photovoltaic tracking system, the slewing drive device is fixed on the column of the photovoltaic tracking system. Adjacent slewing drive devices are connected through the transmission shaft of the photovoltaic tracking system, and power and torque are transmitted through the transmission shaft to ensure the synchronization of each driving point when the photovoltaic module rotates.

When the sag is too large, its rotation will be affected, thereby affecting the synchronization of dynamic torque transmission, and then causing the entire photovoltaic tracking system to be unstable and even structural damage.

DETAILED DESCRIPTION

[0050] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without making novel work are within the scope of protection of the utility model.

[0051] In the description of the present invention, it should be understood that the terms "upper", "lower", "top", "bottom" and the like indicate positions or positional relationships based on the positions or positional relationships shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the positions or elements referred to must have a specific orientation, be constructed and operate in a specific orientation, and therefore cannot be understood as limitations of the present invention. In addition, the terms "first" and "second" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance.

[0052] Combination Figure 1-Figure 6 As shown, the first aspect of the utility model provides a suspension support structure 100, wherein the suspension support structure 100 can be used in a photovoltaic tracking system.

[0053] The suspension support structure 100 includes a suspension connector 101 and a sliding member 102. The suspension connector 101 is mounted on the photovoltaic tracking system and can rotate with the main shaft 200. Specifically, the suspension connector 101 can be mounted on the main shaft 200 of the photovoltaic tracking system. Figure 1 , Figure 2 , Figure 4 and Figure 5 It can also be mounted on the purlin 400 of the photovoltaic tracking system, such as Figure 6 shown.

[0054] like Figure 1-Figure 3 and Figure 6As shown, the sliding member 102 can be slidably mounted on the suspension connector 101, that is, the sliding member 102 can move relative to the suspension connector 101. The transmission shaft of the photovoltaic tracking system can pass through the sliding member 102 and is rotatably connected to the sliding member 102, and the sliding member 102 is used to support the transmission shaft. That is, the support of the transmission shaft by the sliding member 102 suppresses the degree of deflection of the transmission shaft, thereby improving the stability of the entire photovoltaic tracking system. Since the transmission shaft is rotatably connected to the sliding member 102, the free rotation of the transmission shaft is achieved, and the sliding member 102 is prevented from hindering the rotation of the transmission shaft. In addition, the suspension connector 101 can rotate with the main shaft 200, and the sliding member 102 can be slidably mounted on the suspension connector 101, so that the relative rotation of the main shaft 200 and the transmission shaft can be achieved, and the transmission shaft is prevented from interfering with the rotation of the main shaft 200.

It should be noted that the relative motion of the motion track 101a and the sliding member 102 can be specifically a sliding fit between the motion track 101a and the sliding member 102, or a rolling fit. In this embodiment, by making the axis of the motion track 101a coincide with the rotation axis of the main shaft 200, the sliding member 102 can be relatively moved and installed on the motion track 101a to achieve relative rotation between the main shaft 200 and the transmission shaft.

In order to achieve stable sliding of the mounting seat 102-1 relative to the motion track 101a, the cross-sectional shape of the through hole can be set to match the cross-sectional shape of the motion track 101a, and the cross-sectional size of the through hole can be slightly larger than the cross-sectional size of the motion track 101a, so as to facilitate stable sliding between the mounting seat 102-1 and the motion track 101a, and reduce the shaking amount of the mounting seat 102-1.

[0057] The bearing 102-2 is mounted on the mounting seat 102-1, and the transmission shaft passes through the bearing 102-2 and is rotatably connected to the bearing 102-2.

It should be noted that a through hole can also be provided on only one of the first bearing hoop 102-1-1 and the second bearing hoop 102-1-2.
