Background technique

In a solar farm, solar panels or heat collectors are usually arranged in a certain array. There are usually two installation types of solar panels: fixed installation and follow-up installation.

The pitch base 2 of at least one solar cell system 100 is connected with a pitch drive mechanism 7 , and the rotation base 3 of at least one solar cell system 100 is connected with a rotation drive mechanism 8 .

In the prior art, the pitch and rotation of each solar panel are independently driven, so N solar panel arrays require N*2 driving mechanisms, which not only consumes a lot of money, but also increases the complexity of the system, and cannot guarantee that each Both power mechanisms can operate normally or synchronously.

The present invention connects the pitch bases of a plurality of solar battery systems through a pitch synchronization mechanism, and only needs to install a pitch drive mechanism on some of the pitch bases to adjust the pitch angle of all solar battery systems; and connects the pitch angles of multiple solar battery systems through a rotation synchronization mechanism Rotary seat, only need to install a rotary drive mechanism on part of the rotary seat to adjust the rotation angle of the entire solar cell system; the present invention uses a pitch synchronization mechanism and a rotation synchronization mechanism to control the horizontal rotation and pitch action of one or several solar cell panel systems Pass it on to other solar panel systems, so that the attitude of the solar panel array can be adjusted synchronously with the incident angle of sunlight, reduce a large number of driving mechanisms, reduce costs, and ensure the synchronous operation of multiple solar battery systems. In addition, the present invention hinges the rotating base on the pitching base, so that the two actions of pitching and rotating do not affect each other and do not interfere.

The pitch synchronization mechanism and the rotation synchronization mechanism of the present invention can have various forms, such as chain synchronization, connecting rod synchronization and synchronous belt synchronization. Taking the timing belt as an example, the pitch synchronization mechanism 5 of the present invention includes a first group of synchronous pulleys 9, The first group of synchronous pulleys 9 of at least two solar battery systems 100 are connected by a synchronous belt 10; The timing belt 10 is connected.

Taking chains or connecting rods as an example, the pitch synchronization mechanisms are connected to each other through chains or connecting rods, and the rotation synchronization mechanisms are connected to each other through chains or connecting rods.

Usually multiple solar cell systems are arranged rectangularly in rows and columns. For the convenience of expression, for solar panel arrays in solar farms, the definition is as follows: as shown in Figure 10, the same distance from the sun is "row", and the other dimension is "Column", as shown in Figure 10, the solar panels face the south, which is 3 rows and 4 columns. On this basis, the solar panel direction adjustment system of the present invention can be implemented in various ways.

method one:

The number of the first group of synchronous pulleys 9 is 2, which are respectively arranged at the two ends of the pitch seat 2. The first group of synchronous pulleys 9 of the solar cell system 100 on the same column are connected in sequence through the synchronous belt 10, and each column has The pitch seat 2 of a solar cell system 100 is connected with a pitch drive mechanism 7; the number of the second group of synchronous pulleys 11 is 2, and the second group of synchronous pulleys 11 of the solar cell system 100 on the same row passes through the synchronous belt 10 in turn. connection, each row has a rotating seat 3 of a solar cell system 100 connected with a rotating drive mechanism 8 .

As shown in Figure 11, for the convenience of expression, the array is simplified to 3 rows and 3 columns, where 1-2-3 is the row, 1-4-7 is the column, and so on.

If the pitch and rotation of each solar panel are independently driven, then a solar panel array with m rows and n columns requires m*n*2 drive mechanisms. If the array is driven independently in the figure, 18 drive mechanisms are required. The present invention realizes synchronous adjustment of the pitching mechanism and the rotating mechanism of the solar cell panel in an array manner, simplifies the original m*n*2 driving mechanisms into m+n driving mechanisms, saves a large number of driving mechanisms, and reduces costs.

As shown in Figure 8, the swivel seat is a double synchronous wheel structure. In this way, the rotating seat of 2 can be connected with 1 on one side through the timing belt, and can be connected with 3 on the other side at the same time, as shown in Figure 12. In this way, 1 rotates under the action of the rotary drive mechanism, and at the same time drives 2 and 3 to rotate synchronously, and 2 and 3 no longer need the rotary drive mechanism;

As shown in Figures 5 and 6, the pitch seat is also a double synchronous wheel structure. Taking the first column (1-4-7) as an example, the pitch seat of 4 is connected with 1 through a synchronous belt, and on the other side, the pitch seat of 4 is connected with the pitch seat of 7. In this way, 1 pitches under the action of the pitching drive mechanism, and simultaneously drives 4 and 7 to pitch synchronously, and 4 and 7 no longer need the pitching drive mechanism.

To sum up, the first column (1-4-7) in the figure respectively provides rotation power for the solar panels in the same row; the first row (1-2-3) in the figure respectively provides the solar cells in the same column The panels provide the pitching power, and finally only 6 drive mechanisms are needed to realize the synchronous pitching and rotation of the solar panels of the array.

Method 2:

The number of the first group of synchronous pulleys 9 is four, the first group of synchronous pulleys 9 of the solar battery system 100 on the same row are connected sequentially through the synchronous belt 10, and the first group of solar battery systems 100 on the same column are synchronous The pulleys 9 are sequentially connected by a synchronous belt 10, and there is a pitch seat connected to a solar cell system 100 with a pitch drive mechanism 7; the number of the second group of synchronous pulleys 11 is 4, and the solar cell system 100 on the same row Two sets of synchronous pulleys 11 are sequentially connected by synchronous belts 10, and the second set of synchronous pulleys 11 of the solar battery system 100 on the same column are sequentially connected by synchronous belts 10. There is a rotating seat 3 of a solar battery system 100 connected with a rotating Drive mechanism 8.

This method is based on method 1, so that the first group of synchronous pulleys and the second group of synchronous pulleys are respectively added with two synchronous pulleys, so that the first group of synchronous pulleys of each solar cell system are connected to each other, so that The second set of synchronous pulleys of each solar cell system are connected to each other, and only one pitch drive mechanism and one rotation drive mechanism are needed to realize the synchronous pitch and rotation of the solar cell panels of the array. Also, the one pitch drive mechanism and the one rotation drive mechanism may be on one solar cell system, or may be separately on two solar cell systems.
