Description

Technical Field

[0001] This application relates to the technical field of solar power generation equipment, and particularly to a dual-axis rotating device for realizing solar tracking. Background Art

[0002] At present, solar energy has become an important part of the clean energy used by humans and is constantly developing. Solar energy is generally used for power generation or providing energy for water heaters in modern times. There are two ways to utilize solar energy: photothermal conversion and photovoltaic conversion. No matter which conversion method is used, solar panels are required to convert light energy. Therefore, solar brackets are essential equipment in the process of utilizing solar energy.

[0003] Existing solar panels are fixedly installed at a certain fixed position outdoors at a fixed angle. However, the sun changes its position continuously throughout the day, which results in the characteristics of low density and intermittency of solar energy, and the illumination direction and intensity change continuously with time. Traditional solar panel modules are fixed at an angle and cannot always operate at the maximum efficiency. The inclination and direction of the solar panel with respect to the ground are fixed, and thus the light energy cannot be fully utilized. Utility Model Content

[0006] Through the above technical solution, the first motor and the second motor respectively output perpendicular torques, which can not only realize the rotation of the solar panel module in the first and second directions, but also, since the torques are perpendicular to each other, they are extremely difficult to influence each other. Therefore, the adjustment accuracy is higher than that of the existing solution.

[0014] Specifically, the stop bar contacts the convex block when rotating into the limiting area.

[0015] Through the above technical solutions, the limiting blocks and the stop bar rotate following the support frame, start to contact the convex block when rotating into the limiting area, and stop rotating when the stop bar contacts one side of the limiting block, reaching the maximum rotation angle in a certain direction.

[0016] Specifically, it further includes a storage battery; the storage battery is disposed inside the lower housing; and a protective film is wrapped outside the storage battery.

Detailed Description of the Embodiments

[0028] In the following detailed description, reference is made to the accompanying drawings which form a part of the detailed description and which illustrate illustrative specific embodiments in which the present application may be practiced. In this regard, directional terms such as "top", "bottom", "left", "right", "upper", "lower", etc. are used with reference to the orientation of the described figures.

It should be understood that other embodiments may be utilized or logical changes may be made without departing from the scope of the present application. Accordingly, the following detailed description should not be taken in a limiting sense, and the scope of the present application is defined by the appended claims.

[0029] Figure 1 is a schematic structural diagram of a two-axis rotating device for realizing solar tracking according to an embodiment of the present application, as Figure 1 shown, including: a solar cell 1a panel module 1, an adjusting mechanism 2 and a base 3; the adjusting mechanism 2 is configured to adjust the angle of the solar cell 1a panel module 1 in a first direction and a second direction, and the adjusting mechanism 2 is disposed between the base 3 and the solar cell 1a panel module 1.

[0030] Specifically, the solar cell 1a panel module 1 includes: a solar cell 1a panel and a connecting seat 1b; the solar cell 1a panel is disposed on the connecting seat 1b; the connecting seat 1b is connected to a first support arm 2a and a second support arm 2b, and is driven by the first support arm 2a and the second support arm 2b to rotate in the first direction.

[0031] Figure 2 is a schematic structural diagram of an adjusting mechanism of a two-axis rotating device for realizing solar tracking according to an embodiment of the present application Figure 1 、 Figure 3 is a schematic structural diagram of an adjusting mechanism of a two-axis rotating device for realizing solar tracking according to an embodiment of the present application Figure 2 ,as Figure 2-3 shown, the adjusting mechanism 2 includes a first rotating mechanism 4, a second rotating mechanism 5, a support frame 6, a first motor 4a and a second motor 5a. The first motor 4a and the second motor 5a respectively drive the first rotating mechanism 4 and the second rotating mechanism 5 to rotate, and the torque directions output by the first motor 4a and the second motor 5a are perpendicular to each other; the first rotating mechanism 4 is disposed between the solar cell 1a panel module 1 and the second rotating mechanism 5; the first rotating mechanism 4, the second rotating mechanism 5, the first motor 4a and the second motor 5a are disposed on the support frame 6.

[0032] Through the above technical solutions, the first motor 4a and the second motor 5a respectively output torques perpendicular to each other, which can not only realize the rotation of the solar cell 1a panel module 1 in the first and second directions, but also, because the torques are perpendicular to each other, they are extremely difficult to affect each other, so the adjustment accuracy is higher than that of the existing solutions.

[0033] The specific adjusting mechanism 2 further includes an upper housing 2c, a lower housing 2d, a first support arm 2a and a second support arm 2b; the first support arm 2a and the second support arm 2b are symmetrically arranged on both sides of the upper end of the upper housing 2c; a first rotating mechanism 4, a second rotating mechanism 5, a first motor 4a and a second motor 5a are arranged inside the upper housing 2c; the first rotating mechanism 4 drives the first support arm 2a and the second support arm 2b to rotate in the first direction.

[0034] Specifically, the first rotating mechanism 4 includes: a first driving gear 4b, a first driven gear 4c and a first power output shaft; the first driving gear 4b meshes with the first driven gear 4c, the first driving gear 4b and the first driven gear 4c are located in the same vertical horizontal plane, and both the first driving gear 4b and the first driven gear 4c are perpendicular to the base 3; the first power output shaft is arranged on the outer end face of the first driven gear 4c, so as to drive the first support arm 2a or the second support arm 2b to rotate.

[0035] Specifically, the second rotating mechanism 5 includes: a second driving gear 5b, a second driven gear 5c and a second power output shaft; the second driving gear 5b meshes with the second driven gear 5c, the second driving gear 5b and the second driven gear 5c are located in the same horizontal plane, and both the second driving gear 5b and the second driven gear 5c are parallel to the base 3; the second power output shaft is arranged on the end face of the second driven gear 5c close to the lower housing 2d.

[0036] Specifically, a limiting block 7 is arranged on the lower end face of the support frame 6.

[0037] Figure 4 It is a schematic structural diagram of the lower housing of a two-axis rotating device for realizing solar tracking according to an embodiment of the present application, as Figure 4 shown, a shaft seat 9 for cooperating with the second power output shaft is arranged on the upper end face of the lower housing 2d; a convex block 9a is arranged on the outer end face of the shaft seat 9 in the horizontal direction.

[0038] Specifically, a swingable stop bar 8 is arranged between the limiting blocks 7; the limiting blocks 7 and the stop bar 8 rotate following the support frame 6.

[0039] Specifically, the stop bar 8 contacts the stop bar 8 when rotating into the limiting area.

[0040] Through the above technical solutions, the limiting blocks 7 and the stop bar 8 rotate following the support frame 6, start to contact the convex block 9a when rotating into the limiting area, and when the stop bar 8 contacts the limiting block 7, the rotation stops, reaching the maximum rotation angle.

[0041] Figure 5 It is a sectional view of the lower housing of a two-axis rotating device for realizing solar tracking according to an embodiment of the present application, as Figure 5As shown, it further includes a storage battery 10; the storage battery 10 is arranged inside the lower housing 2d; and a protective film 11 is wrapped around the outside of the storage battery 10.

[0042] When the present application works, the second motor 5a outputs a torque in the horizontal direction, and the power is transmitted through the second driving gear 5b, the second driven gear 5c, the second output shaft 5d and the shaft seat 9 to make the solar cell 1a module rotate in the horizontal direction. More specifically, when rotating in the horizontal direction, the convex block 9a rotates accordingly. When the convex block 9a contacts the stop lever 8, the rotation of the device in the horizontal direction enters the limit control area. When reaching the maximum limit boundary on one side of the limit control area, the stop lever 8 abuts against the limit block 7 on one side. The size of the limit control area mentioned here is the same as the swing area of the stop lever 8, and the torque output by the second motor 5a will be inhibited to a certain extent within this area to avoid situations such as the breakage of the stop lever 8 or the convex block 9a due to excessive torque resulting in device damage.

[0043] In addition, the present application can achieve the following effects by combining existing technologies such as communication and algorithm control:

[0044] (1) The host computer calculates the altitude angle and azimuth angle of the sun based on the change in the incident angle of sunlight, and thus calculates the angles that the first rotating mechanism and the second rotating mechanism need to rotate, so as to achieve real-time or intermittent tracking of the sun;

[0045] (2) By sending adjustment instructions to this device through a mobile terminal, remote control of the rotation direction and angle can be achieved.

[0046] Obviously, those skilled in the art can make various modifications and changes to the embodiments of the present application without departing from the spirit and scope of the present application. In this way, if these modifications and changes are within the scope of the claims of the present application and their equivalent forms, the present application also aims to cover these modifications and changes. The word "comprising" does not exclude the presence of other elements or steps not listed in the claims. The simple fact that certain measures are recited in mutually different dependent claims does not indicate that a combination of these measures cannot be used to advantage. Any reference signs in the claims should not be construed as limiting the scope.
