Abstract
Description

[0001] The present invention relates to the field of photovoltaic solar energy technology, and in particular to an all-terrain tracking slewing reducer. Background Art
[0002] The increasing capacity of photovoltaic power stations is leading to a decrease in the availability of prime resources for power station construction. Lower-quality resources, such as mountainous and sloping land, are gaining increasing attention, and the construction of "mountain photovoltaic power stations" is on the rise. my country has numerous subsidence areas caused by coal and mineral mining, providing ample land for the construction of solar photovoltaic power stations.
[0003] Compared to deserts and Gobi regions, mountainous areas have more complex terrain, resulting in difficulties aligning PV system spacing with natural conditions, uncontrollable investment costs, and high subsequent operation and maintenance costs. Therefore, in engineering design, comprehensive considerations should be given to PV power generation efficiency, system-environmental coordination, and economic safety. The quality of bracket installation must be strictly managed to ensure that each bracket set meets quality requirements.
[0004] Compared with the construction of photovoltaic power stations in plain areas, photovoltaic power stations built in complex terrain conditions such as mountains and hills have uneven ground, different directions, local ditches, different scales, relatively scattered plots, resulting in module orientation, inconsistent power generation, and serious mismatch of photovoltaic components, which puts higher requirements on the fine design of the power station and inverter technology.

The outer end surface of the horizontal shaft sleeve is flush with the outer end surface of the horizontal pin shaft, and a pair of oil seal caps are connected to the outer end surfaces of the two, so as to prevent water, dust and oil leakage.

[0011] Furthermore, two skeleton oil seals are respectively connected to the connection between the rotating shaft and the main shaft flange, and the connection between the rotating shaft and the base.
[0012] Furthermore, the diameter of the vertical pin shaft is greater than the diameter of the horizontal pin shaft, and the horizontal pin shaft vertically passes through the middle of the vertical pin shaft and its two ends extend out of the vertical pin shaft.

The U-shaped opening is arranged opposite the square shaft, and the two hinged ears are respectively connected to the two ends of the horizontal pin shaft.

[0017] Furthermore, the worm is horizontally connected to the base through a pair of bearings, one end of which is connected to the output end of the reduction motor, and the other end extends out of the base and is set as a worm output shaft for linking multiple reducers.
[0018] In the technical solution of the present invention, by adding a universal joint part, it can rotate a certain angle with the main beam.

[0028] Example 1
[0029] In order to make the present invention more clear, the following further describes an all-terrain tracking rotary reducer of the present invention with reference to the accompanying drawings. The specific embodiments described here are only used to explain the present invention and are not used to limit the present invention.
[0030] Referring to Figures 1 and 2, an all-terrain tracking slewing reducer includes a base 2 connected to a base 1, a spindle flange 3 connected to one side of the base 2, a matching rotating shaft 4 connected to the spindle flange 3, a worm 5 meshing with the rotating shaft 4 connected to the base 1, and one end of the worm 5 is connected to a reduction motor 6. The characteristics are:
[0031] 5, 6 and 9, the worm 5 is horizontally connected to the base 1 through a pair of bearings 16, one end of which is connected to the output end of the reduction motor 6, and the other end extends out of the base 1 and is set as the worm output shaft 5a, so as to be used to link multiple reducers;
[0032] Referring to Figures 3, 4, 7 and 8, two skeleton oil seals 15 are respectively connected to the connection between the rotating shaft 4 and the main shaft flange 3, and the connection between the rotating shaft 4 and the base 2. The rotating shaft 4 rotates along its axis in the cavity formed by the base 2 and the main shaft flange 3. The portion of the rotating shaft 4 located in the cavity is provided with an engaging section 41, which is engaged with the worm 5. The axis of the worm 5 and the axis of the rotating shaft 4 are both located in a horizontal plane and are perpendicular to each other.
[0033] A square shaft 7 connected to the rotating shaft 4 is provided on the other side of the base 2, and the axis of the square shaft 7 coincides with the axis of the rotating shaft 4;
[0034] 7 and 8 , a vertical pin 8 and a horizontal pin 9 are connected to the square shaft 7. The vertical pin 8 is vertically cross-connected with the horizontal pin 9. The diameter of the vertical pin 8 is larger than that of the horizontal pin 9. The horizontal pin 9 vertically passes through the middle of the vertical pin 8 and its two ends extend outside the vertical pin 8.
[0035] A pair of vertical sleeves 10 and a pair of horizontal sleeves 11 are respectively sleeved between the ends of the vertical pin shaft 8 and the horizontal pin shaft 9 and the square shaft. The outer end surface of the vertical sleeve 10 is flush with the outer end surface of the vertical pin shaft 8, and a pair of oil seal caps 12 are connected to the outer end surfaces of the two. The outer end surface of the horizontal sleeve 11 is flush with the outer end surface of the horizontal pin shaft 9, and a pair of oil seal caps 13 are connected to the outer end surfaces of the two to prevent water, dust and oil leakage.
[0036] 5 to 7 , the horizontal pin 9 is connected to a universal seat 14. A pair of hinged ears 141 are provided on the side of the universal seat 14 close to the square shaft 7. A U-shaped opening 141a is formed between the two hinged ears 141. The U-shaped opening 141a is provided opposite the square shaft 7. The two hinged ears 141 are respectively connected to the two ends of the horizontal pin 9. With the axis of the square shaft 7 as the 0° direction, the universal seat 14 rotates around the horizontal pin 9 by ±90°.
[0037] In this embodiment, referring to FIG. 1 and FIG. 2 , the base 1 is composed of four supporting legs, with each pair of two supporting legs forming a pair. The two pairs of supporting legs are respectively fixed on both sides of the bottom of the base 2 and the spindle flange 3 to play a supporting, fixing and connecting role.
[0038] During use, the device is fixed on the equipment through the base 1. When the reduction motor 6 drives the worm 5 to rotate, the worm 5 drives the rotating shaft 4 to rotate in the cavity of the flange and the base through the meshing section 41 with the rotating shaft 4, thereby driving the square shaft 7 to rotate together. Since the vertical pin shaft 8 is connected to the square shaft 7, the vertical pin shaft 8 can not only rotate around its own axis, but also rotate circumferentially with the square shaft 7. The rotation of the vertical pin shaft 8 drives the universal seat 14 connected to the horizontal pin shaft 9 to rotate together. At the same time, the universal seat 14 can also rotate around the horizontal pin shaft 9, which is equivalent to the universal seat 14 having rotation in all degrees of freedom, satisfying the adaptability of the reducer under uneven and complex terrain.
[0039] In addition to the above embodiments, the present invention may also have other implementations. Any technical solution formed by equivalent replacement or equivalent transformation falls within the scope of protection required by the present invention.
