[0002] The photovoltaic tracking system is a system that can automatically track the sun and increase overall power generation, and has the advantage of good tracking performance.

[0003] The slewing reducer drive assembly is an important component of the photovoltaic tracking system. The main shaft is generally driven by the central shaft of the slewing reducer. However, the connection performance between the central shaft of the slewing reducer and the main shaft is poor, which not only easily leads to deformation of the main shaft, but also easily leads to low pressure limit of the main shaft hole wall. At the same time, when the pressure limit of the main shaft hole wall cannot meet the requirements, the entire main shaft can only be thickened, which is not economical. Utility Model Content

[0004] In view of the above technical problems, the utility model provides a driving connection structure and a photovoltaic tracking system, which can not only limit the deformation of the main shaft, but also improve the bearing limit of the hole wall of the main shaft, and at the same time have good economy.

[0010] Wherein, the main shaft, the first clamp, the second clamp and the central shaft are all detachably connected via a first bolt assembly.

[0011] Optionally, the first hoop includes a hoop body one, and two first connecting plates respectively connected to the two sides of the hoop body one; the second hoop includes a hoop body two, and two second connecting plates respectively connected to the two sides of the hoop body two; wherein, the hoop body one and the hoop body two are both wrapped outside the main shaft, the two first connecting plates and the two second connecting plates are correspondingly detachably connected, and the main shaft, the hoop body one, the hoop body two and the central axis are all detachably connected via a first bolt assembly.

[0012] Optionally, the connection between the clamp body 1 and the two first connecting pieces is an integrally formed connection; the connection between the clamp body 2 and the two second connecting pieces is an integrally formed connection.

[0013] Optionally, the two first connecting plates and the two second connecting plates are detachably connected to each other via a second bolt assembly.

[0014] Optionally, the cross-sectional shape of the main shaft, the cross-sectional shape formed by the first hoop and the second hoop, and the cross-sectional shape of the central shaft are all non-rotating shapes.

[0015] A photovoltaic tracking system includes a driving connection structure.

[0016] The technical solution provided by the utility model has the following beneficial effects compared with the prior art: the main shaft is clamped by the first clamp and the second clamp, which is convenient for limiting the deformation of the main shaft, and at the same time, the local thickening of the main shaft is achieved, thereby improving the pressure bearing limit of the hole wall of the main shaft, and when the pressure bearing limit of the hole wall of the main shaft cannot meet the requirements, the pressure bearing limit of the hole wall of the main shaft can be improved by thickening the first clamp and the second clamp, without thickening the entire main shaft, which is economical.

[0023] Example 1

[0024] Combined with Figure 1-3 , this embodiment provides a drive connection structure, including:

[0025] Spindle 3;

[0026] A first clamp 1 and a second clamp 2 are both wrapped around the main shaft 3, and the first clamp 1 and the second clamp 2 are detachably connected;

[0027] A central shaft 4 of a rotary reducer 6 sleeved in the main shaft 3;

[0028] The main shaft 3 , the first clamp 1 , the second clamp 2 and the central shaft 4 are all detachably connected via a first bolt assembly 51 .

[0029] Specifically, during installation, first wrap the first clamp 1 and the second clamp 2 around the main shaft 3; then, detachably connect the first clamp 1 and the second clamp 2 together, so that the first clamp 1, the second clamp 2 and the main shaft 3 are clamped into a whole; then, the main shaft 3 is sleeved outside the middle shaft 4, and the main shaft 3, the first clamp 1, the second clamp 2 and the middle shaft 4 are detachably connected together through the first bolt assembly 51; in summary, the main shaft 3 is clamped by the first clamp 1 and the second clamp 2, so as to limit the deformation of the main shaft 3 and realize local thickening of the main shaft 3, thereby improving the pressure limit of the hole wall of the main shaft 3, and when the pressure limit of the hole wall of the main shaft 3 cannot meet the requirements, the pressure limit of the hole wall of the main shaft 3 can be improved by thickening the first clamp 1 and the second clamp 2, without thickening the entire main shaft 3, which is economical.

[0030] Further, such as Figure 2 The first clamp 1 includes a clamp body 11, and two first connecting pieces 12 respectively connected to the two sides of the clamp body 11; the second clamp 2 includes a clamp body 21, and two second connecting pieces 22 respectively connected to the two sides of the clamp body 21; wherein, the clamp body 11 and the clamp body 21 are both wrapped outside the main shaft 3, the two first connecting pieces 12 and the two second connecting pieces 22 are correspondingly detachably connected, and the main shaft 3, the clamp body 11, the clamp body 21 and the middle shaft 4 are all detachably connected through the first bolt assembly 51.

[0031] Specifically, the two first connecting pieces 12 and the two second connecting pieces 22 facilitate the connection between the first clamp 1 and the second clamp 2 .

[0032] Further, such as Figure 2 The connection between the clamp body 11 and the two first connecting pieces 12 is an integrally formed connection; the connection between the clamp body 21 and the two second connecting pieces 22 is an integrally formed connection.

[0033] Specifically, the one-piece connection facilitates the good integrity of the clamp body 11 and the two first connecting pieces 12 ; the one-piece connection facilitates the good integrity of the clamp body 21 and the two second connecting pieces 22 .

[0034] Further, such as Figure 1-3 The two first connecting plates 12 and the two second connecting plates 22 are correspondingly detachably connected via the second bolt assembly 52 .
