Description

Technical Field

[0001] The utility model belongs to the field of photovoltaic power generation equipment, and particularly relates to a multi-point linkage photovoltaic adjusting mechanism. Background Art

[0002] In order to increase the power generation amount, a photovoltaic power generation device usually consists of multiple solar panels to form a power generation matrix. And in order to improve the power generation efficiency, it is necessary to make it capable of sun-tracking adjustment through an adjusting mechanism. Most of the existing photovoltaic tracking brackets are equipped with a separate motor for the adjusting mechanism of each bracket for single-point adjustment, and their linkage performance is poor. When performing sun-tracking adjustment on a large-area solar panel matrix, such photovoltaic tracking brackets need to be adjusted one by one, which is rather cumbersome. Therefore, there is an urgent need for a multi-point linkage photovoltaic adjusting mechanism with high synchronism to solve this problem. Summary of the Utility Model

[0003] Based on the content in the background art, the utility model discloses a multi-point linkage photovoltaic adjusting mechanism, which includes a plurality of reducers arranged in a straight line. The relative ends of the input shafts of adjacent reducers are respectively fixedly connected with couplings, and adjacent couplings are fixedly connected through a connecting shaft. The other end of the input shaft of the reducer at the head end is further connected with a driving motor. The central shafts of each reducer share the same axis and are fixedly connected to the rotating shaft of the photovoltaic bracket.

[0004] Thus, when the input shaft of the reducer at the head end is driven by the driving motor, the rotational torque will be transmitted to the input shafts of each reducer through the couplings and the connecting shaft, and then the central shafts of each reducer drive the rotating shaft of the photovoltaic bracket to achieve multi-point linkage adjustment, which has the excellent characteristics of high reliability and high synchronism.

[0005] Preferably, the central shaft of the reducer is a hollow shaft, and this central shaft is sleeved on the rotating shaft of the photovoltaic bracket.

[0006] Preferably, a worm, a worm gear, a first helical gear and a second helical gear are rotatably connected inside the housing of the reducer. The above-mentioned components are rotatably connected by arranging bearings between their shafts and the inner wall of the housing. The input shaft of the reducer is integrally connected with the worm, and the second helical gear is fixedly connected to the central shaft of the reducer, that is, the second helical gear is sleeved on this central shaft, and this central shaft is the shaft of the second helical gear;

[0007] The spiral teeth of the worm are engaged with the tooth blocks of the worm wheel. A first helical gear is fixedly connected to the shaft rod of the worm wheel. The first helical gear is engaged with the second helical gear, and the axis of the second helical gear is perpendicular to the axis of the first helical gear. In this way, the transmission direction is realized through the engagement mode of the two helical gears. The above structure enables the reducer to have a two-stage deceleration function, with excellent deceleration effect and stable torque transmission. When the input shaft of the reducer rotates, the rotational torque is transmitted from the worm to the worm wheel to achieve the first deceleration, and then is transmitted from the first helical gear on the shaft rod of the worm wheel to the second helical gear to achieve the second deceleration. Finally, the decelerated rotational torque is output by the central shaft.

[0008] Through the above technical solutions, the present utility model has at least the following beneficial effects:

[0009] In the multi-point linkage photovoltaic adjustment mechanism described in the present application, each reducer is mechanically driven through a coupling and a connecting shaft, and a single driving motor can be used to run synchronously to perform multi-point linkage sun-tracking adjustment on the rotating shaft of the photovoltaic support, having the excellent characteristics of high reliability and high synchronism.

[0010] In a preferred embodiment, the reducer of the multi-point linkage photovoltaic adjustment mechanism is designed with components such as a worm, a worm wheel, a first helical gear, and a second helical gear, so that it has a two-stage deceleration function, with excellent deceleration effect and stable torque transmission, enabling the multi-point linkage photovoltaic adjustment mechanism to have a high torque power transmission efficiency. Under the same power of the driving motor, more reducers can be connected to form more linkage points, enabling more solar panels to be adjusted synchronously. BRIEF DESCRIPTION OF THE DRAWINGS

[0016] Reference Figure 1 A multi-point linkage photovoltaic adjusting mechanism, which includes a plurality of reducers 1 arranged in a straight line. The relative ends of the input shafts of adjacent reducers 1 are respectively fixedly connected with couplings 2. The adjacent couplings 2 are fixedly connected through a connecting shaft 3. The other end of the input shaft of the reducer 1 at the head end is also connected with a driving motor 4. The central shafts 5 of each reducer 1 share the same axis and are fixedly connected to the rotating shaft of the photovoltaic support; the central shaft 5 of the reducer 1 is specifically a hollow shaft, and this central shaft 5 is sleeved on the rotating shaft of the photovoltaic support.

[0017] Thus, when the input shaft of the reducer 1 at the head end is driven by the driving motor 4, the rotational torque will be transmitted to the input shafts of each reducer 1 through the couplings 2 and the connecting shaft 3, and then the central shafts 5 of each reducer 1 will drive the rotating shaft of the photovoltaic support to achieve multi-point linkage adjustment. Such an adjustment and transmission method has excellent characteristics of high reliability and high synchronism.

[0018] Reference Figure 2, a worm 102, a worm wheel 103, a first helical gear, and a second helical gear 104 are rotatably connected inside the housing 101 of the speed reducer 1. The rotational connection of each of the above components is achieved by providing bearings between their shafts and the inner wall of the housing 101. The input shaft of the speed reducer 1 is integrally connected to the worm 102. The second helical gear 104 is fixedly connected to the central shaft 5 of the speed reducer 1, that is, the second helical gear 104 is fitted and sleeved on the central shaft 5, and this central shaft 5 is the shaft of the second helical gear 104;

[0019] The helical teeth of the worm 102 mesh with the tooth blocks of the worm wheel 103. A first helical gear is fixedly connected to the shaft of the worm wheel 103. The first helical gear meshes with the second helical gear 104, and the axis of the second helical gear 104 is perpendicular to the axis of the first helical gear. In this way, the transmission direction is achieved through the meshing mode of the two helical gears. The above structure enables the speed reducer 1 to have a two-stage deceleration function, with excellent deceleration effect, stable torque transmission, and high efficiency. When the input shaft of the speed reducer 1 rotates, the rotational torque is transmitted from the worm 102 to the worm wheel 103 to achieve the first deceleration, and then transmitted from the first helical gear on the shaft of the worm wheel 103 to the second helical gear 104 to achieve the second deceleration. Finally, the decelerated rotational torque is output by the central shaft 5.

[0020] The multi-point linkage photovoltaic adjustment mechanism of the present application cooperates with the above speed reducer 1 with high torque transmission stability and high efficiency. Under the same power of the driving motor 4, more speed reducers 1 can be connected to form more linkage points, enabling more solar panels to be adjusted synchronously.
