When the half wheel 31 rotates the rotating shaft 2, the half wheel 31 is parallel to the Z-Y plane (see the coordinate axes shown in fig. 3). At present, a photovoltaic tracker with the driving wheel device can only be suitable for being installed on a horizontal or nearly horizontal flat ground, but the construction land of all photovoltaic power stations is not horizontal, and for places with slopes, when the ground is at any slope, motors (or speed reducers) installed on half wheels and stand columns deviate from the original installation position. The included angle between half wheel and the half wheel mounting needs can adapt to the problem that changes installation angle because of the ground slope changes. This is one of them.

Secondly, when the half wheel 31 needs to rotate a certain angle with respect to the X axis (see the coordinate axes shown in fig. 6) to adjust the solar panel, the half wheel 31 further deviates from the original installation position where it needs to be combined with the motor (or the speed reducer 4).

Thirdly, when the half wheel 31 needs to be turned by a certain angle around the Z axis (see the coordinate axes shown in fig. 6), the half wheel 31 may be further deviated from the installation position where it needs to be combined with the motor (or the speed reducer 4).

The three aspects increase the technical difficulty of installation on different ground slopes and have the technical problem of difficult adjustment.

Example 1

Referring to fig. 7 to 9, an adaptive double-shaft adjusting driving wheel device includes a half wheel 100, a double-shaft member 200, a main shaft fixing member 300, and a speed reducer 400. As another specific embodiment, the speed reducer may be replaced by a motor. The present embodiment will be described by taking a speed reducer as an example.

The half wheel 100 is provided with a Z-axis hole 101 at its middle end, see the coordinate axes shown in fig. 7 or fig. 8. It should be noted that, in order to better understand the orientation, the present embodiment refers to coordinate axes of the X axis, the Y axis, and the Z axis shown in fig. 7. The coordinate axes are for better understanding only and do not indicate or imply that the component or element being referred to must have an axial orientation under that name, and the identity of the X, Y, and Z axes should be understood when they are rotated in space, e.g., so that the original X axis is changed from the Z axis, the original Y axis is changed from the X axis, and the original Z axis is changed from the Y axis. The present embodiment is described with three-axis coordinates as shown in fig. 7 or fig. 8. The Z-axis hole can be a one-stage type or a two-stage interval type. The present embodiment is two-stage compartmentalized.

The lower end of the double-shaft member 200 is provided with a Z-shaft member 201, the upper end thereof is provided with a first X-shaft hole 202, and the Z-shaft member 201 is inserted into the Z-shaft hole 101, so that the half wheel can rotate around the Z-shaft. In order to make the Z-axis member relatively immovable, a pin 203 may be further inserted, and an opening 204 may be provided at the other end of the pin 203, and a cotter pin 205 may be inserted into the opening 204 to be fixed. Thus, referring to fig. 10, half wheel 100 can rotate about Z-axis 201, i.e., about Z-axis 206.

A spindle holder 300 for holding the spindle in the Y-axis direction; the lower end of the main shaft fixture 300 is provided with a second X-axis hole 301, and an insertion shaft 302 is inserted into the first X-axis hole 202 and the second X-axis hole 301, so that the main shaft fixture 300 can rotate around the X-axis. In one embodiment, referring to fig. 8, the first X-axis hole 202 is two separate shaft holes, and the second X-axis hole 301 is a long-strip-shaped shaft hole, which is located between the two separate shaft holes and is inserted into the first X-axis hole 202 and the second X-axis hole 301 through the insertion shaft 303. In another specific embodiment, referring to fig. 8, the first X-axis hole 202 is a long strip-shaped shaft hole, the second X-axis hole 301 is two separate shaft holes, and the long strip-shaped shaft hole is located between the two separate shaft holes and is inserted into the first X-axis hole 202 and the second X-axis hole 301 through the insertion shaft 303. To prevent the shaft from disengaging, either the first or second embodiments, the fastener 304 may be selected to secure the shaft. The fastener can be a pin sleeve or a bolt sleeve, and the pin sleeve or the bolt sleeve fixes the inserting shaft in the first X-axis hole and the second X-axis hole. Thus, referring to fig. 11, half wheel 100 can rotate about the spiale, i.e. about the X-axis 305; and does not allow half wheel 100 to slip out.

And a reduction gear 400 connected to the half wheel 100, so that the reduction gear 400 drives the half wheel 100 to rotate. The reducer is provided with a reduction gear 401 and a reduction gear 402 connected to the reduction gear 401. Two embodiments are possible, one embodiment is shown in fig. 12-13. Chain 102 is provided around wheel half 100, and chain 102 is connected to a reduction gear 401. Rotation of the reduction gear 401 causes rotation of the chain 102 and thus rotation of the half-wheel 100. In another embodiment, as shown in fig. 14-15, gear 103 is disposed on the periphery of half wheel 100, and gear 103 is engaged with reduction wheel 401. The rotation of gear 103 and thus of half-wheel 100 is driven by the rotation of reduction wheel 401.

As a specific embodiment, referring to fig. 7 to 9, the spindle fixing member 300 includes a first half fixing member 307 and a second half fixing member 308, and the first half fixing member 307 and the second half fixing member 308 can surround the spindle and then be fixed by a bolt 309; the second X-axis hole 301 is disposed at the lower end of the second half fixing member 308. Therefore, the main shaft fixing piece is divided into two parts, and the main shaft fixing piece can be conveniently arranged on the main shaft.

Specifically, the travel switch 403 having the striker 404 may be fixed to the reduction box 402. When the half wheel 100 rotates to a predetermined angle, the position-limiting member 104 touches the touch head 404 of the travel switch 403, which causes the travel switch 403 to be powered off or the output to be reversed.

In order to make the half wheels rotate stably, two embodiments can be further adopted, one embodiment is shown in fig. 18-19, a limiting wheel 405 is fixed on the speed reducer 400, the half wheel 100 is provided with a half wheel groove, and the limiting wheel 405 is located in the half wheel groove. Thus, the half wheel 100 is stably rotated by the stopper wheel 405. In another specific embodiment, referring to fig. 20, a speed reducer 400 is fixed with limiting wheels 405, and the number of the limiting wheels 405 is not limited, with 2 limiting wheels forming a group. The 2 wheels 405 of a set are spaced apart so that the half wheel 100 is between the 2 wheels 405. This embodiment may employ 2 sets of wheels 405. Thus, the half wheel 100 is stably rotated by the stopper operation of the 2 sets of stopper wheels 405.

Due to the arrangement of the double-shaft part 200, the half wheel 100 is connected with the double-shaft part 200, so that the half wheel 100 can rotate around the X axis, the installation of the ground with a slope can be adjusted in a self-adaptive manner, and the angle of the half wheel relative to the X axis can be adjusted in a self-adaptive manner; due to the arrangement of the double-shaft piece 200, the half wheel 100 is connected with the double-shaft piece 200, so that the half wheel 100 can rotate around the Z axis, and the deflection angle of the half wheel around the Z axis can be adjusted in a self-adaptive mode.

In conclusion, the driving wheel device with the self-adaptive double-shaft adjustment can enable the installation position of the half wheel combined with the motor (or the speed reducer) not to be affected, can adapt to installation of different ground slopes and can self-adaptively double-shaft adjust.
