In particular, in this embodiment, the main drive column 2 comprises two parts, a first pile base and a drive means 2-2. The first pile foundation body is arranged on the ground and mainly provides support for the transmission device 2-2. The transmission 2-2 is arranged on top of the first pile base body. The transmission device 2-2 comprises a speed reducer 2-2-1, a swing rod 2-2-2, a push-pull rod 2-2-3 and a second connecting rod 2-2-4. Wherein, the speed reducer 2-2-1 is controlled by a motor, and a transmission shaft of the speed reducer 2-2-1 is connected with one end of the swing rod 2-2-2. The length direction of the transmission shaft is vertical to the length direction of the swing rod 2-2-2.

Specifically, the second pile base body is arranged on the ground like the first pile base body and provides support for the upright posts 3-2. The upright post 3-2 is integrally erected on the top of the second pile foundation 3-1. The top side edge of the upright post 3-2 is provided with a circular ring part 3-3, and the main shaft 1-1 passes through the circular ring part 3-3 and is connected with the circular ring part 3-3 through a bearing, so that the main shaft 1-1 can rotate in the circular ring part 3-3 through the bearing. The number of slave drive columns 3 may depend on the length of the rotor 1.
The connection relationship among the main transmission column 2, the auxiliary transmission column 3 and the rotor 1 is constructed through the structure. The main transmission column 2 drives the swing rod 2-2-2 to rotate in the horizontal direction through a transmission shaft of the speed reducer 2-2-1. When the swing rod 2-2-2 rotates horizontally, the swing rod 2-2-2 pulls or pushes the push-pull rod 2-2-3 through the second connecting rod 2-2-4. Because the push-pull rod 2-2-3 is connected with the inclined struts 1-3 through the first connecting rods 1-5, when the push-pull rod 2-2-3 is stressed, a pulling force or a pushing force is applied to one of the inclined struts 1-3, and the stress of the two inclined struts 1-3 is unbalanced. Thus, the rotor 1 as a whole rotates about the main shaft 1-1. As the main shaft 1-1 is arranged in the circular ring part 3-3 of the driven transmission column 3, the rotor 1 can incline on the main transmission column 2 and the driven transmission column 3, and finally the inclination angle between the rotor 1 and the horizontal plane is changed, so that the tracking of sunlight is realized.
In this embodiment, in order to more specifically explain the working principle of the horizontal cross photovoltaic control device proposed in this embodiment, reference may be made to the state diagrams of the horizontal cross photovoltaic control device shown in fig. 8 and 9. Fig. 8 shows a state of the photovoltaic module 4 at the time when the inclination angle from the horizontal plane is maximum. At the moment, the inclined strut 1-3, the push-pull rod 2-2-3 and the oscillating bar 2-2-2 are positioned on the same plane and are vertical planes. The length of the push-pull rod 2-2-3 in the vertical direction reaches a maximum value, so that the photovoltaic module 4 is inclined downwards at a position far away from one side of the push-pull rod 2-2-3. When the speed reducer 2-2-1 starts to work and the transmission shaft drives the swing rod 2-2-2 to rotate on the horizontal plane, the length of the push-pull rod 2-2-3 in the vertical direction is gradually reduced because the swing rod 2-2-2 applies a horizontal pulling force to the bottom of the push-pull rod 2-2-3. Meanwhile, the push-pull rod 2-2-3 pulls the inclined strut 1-3, so that the photovoltaic module 4 moves upwards gradually from the position on one side of the push-pull rod 2-2-3, and finally reaches the position shown in fig. 9. In the above process, the change of the inclination angle between the horizontal control photovoltaic module 4 and the horizontal plane is realized. Of course, the position shown in fig. 9 is not the final position, and this embodiment will be discussed only as one possible case. The structures shown in fig. 8 and 9 are only simple and schematic, and there may be some errors in the position states, but in combination with the text description, a person skilled in the art may avoid the errors to implement the solution proposed in the present embodiment.
In this embodiment, the plane on which the swing link 2-2-2 rotates may be connected to limit the rotation angle of the swing link 2-2-2 through a limit structure. The relationship between the rotating speed of the oscillating bar 2-2-2 and the integral rotating speed of the rotor 1 is simple, the control is easy, the rotating speed is uniform, the power is constant, and the protective effect on the speed reducer 2-2-1 and the integral structure is good. Meanwhile, the height of the driving center is reduced through the horizontal transmission of the swing rod 2-2-2, so that the load borne by the foundation is reduced, the cost of the pile foundation column is reduced, and the overall reliability of the device is improved. The transmission device 2-2 is integrally positioned below the photovoltaic modules 4, so that the arrangement of the photovoltaic modules 4 is not influenced, the photovoltaic modules 4 can be fully distributed on the rotor 1, and the land utilization rate is improved.
Example 2
The embodiment provides a horizontal cross photovoltaic control system, which comprises at least one horizontal cross photovoltaic control device. The specific structure and principle of the horizontal cross photovoltaic control device can refer to the content described in embodiment 1, and this embodiment is not described herein again.
When the number of the horizontal cross photovoltaic control devices is plural, two horizontal cross photovoltaic control devices adjacent to each other may be connected by using the connecting rod 5, as shown in fig. 10. Specifically, two ends of the connecting rod 5 can be respectively connected to the speed reduction input ends of the two horizontal cross photovoltaic control devices, one speed reducer 2-2-1 of the horizontal cross photovoltaic control devices is provided with a motor drive, and the other speed reducers 2-2-1 are not provided with the motor drives. The speed reducer 2-2-1 driven by the mounting motor drives other speed reducers 2-2-1 to synchronously rotate, so that all the horizontal cross photovoltaic control devices are synchronous.
Simultaneously, in order to make horizontal cross photovoltaic control system possess better topography adaptability. A universal joint 6 can be adopted for connection between the connecting rod 5 and the horizontal cross photovoltaic control device.
The inclination angle control of the photovoltaic module 4 is realized by the horizontal rotation mode of the transmission device 2-2. The horizontal rotating structure is not affected by the sinking of the pile foundation, and the reliability and the stability of the whole device are improved. The relation between the rotating speed of the transmission device 2-2 and the rotating speed of the motor is simpler, the control is easier, and the uniform rotating speed and the constant power can be maintained. Has good protection effect on the motor and the structure.
