Description

Technical Field

[0001] The invention relates to a solar power generation device with an automatic tracking function, belonging to the technical field of solar power generation. Background Art

[0002] The solar panels (also known as solar cell modules) commonly used in the market are fixed in one position, and the angle at which they can receive sunlight is fixed. However, due to the rotation of the earth itself and its revolution around the sun, the incident angle of sunlight on the solar panels will vary depending on the latitude, season, and even the time of day in the morning and afternoon. Therefore, the solar panels with fixed angles cannot effectively receive the incident sunlight, resulting in the solar panels being unable to be fully utilized. For this reason, relevant practitioners have designed a variety of power generation devices that can track the sun, so that the solar panels face the sun as much as possible and improve their utilization rate. However, most of these solar power generation devices with tracking functions in the prior art have the defects of complex structure, high cost, high consumption of reserve power, poor working stability, and inconvenient operation and use, and therefore need to be improved. Summary of the invention

[0003] In order to overcome the above-mentioned deficiencies of the prior art, the object of the present invention is to provide a solar power generation device with simple structure, low cost, low energy consumption, convenient operation and use, high reliability, and the ability to fully improve the utilization rate of solar energy.

[0004] The purpose of the present invention is achieved through the following technical solutions:

[0005] A solar power generation device with an automatic tracking function comprises a bracket, at least one solar cell assembly rotatably arranged on the bracket, and a tracking mechanism for controlling the rotation of the solar cell assembly to achieve a tracking function. The tracking mechanism comprises a controller, a motor, a transmission mechanism, a swing rod and a support arm. The controller is electrically connected to the motor to control the timing of the motor. The motor drives the swing rod to swing via the transmission mechanism. The lower end of the support arm is hinged to the swing rod, and the upper end of the support arm is fixedly connected to the solar cell assembly.

[0006] Furthermore, the transmission mechanism includes a screw and a screw nut, the screw is connected to the motor, the screw nut is sleeved on the screw, and the rocker arm is connected to the screw nut via a connecting assembly.

[0007] Furthermore, the connecting assembly includes a sliding seat fixed on the screw nut and a vertical sliding rod fixed on the swing rod, and the vertical sliding rod can be slidably inserted into the sliding seat.

[0008] Furthermore, the swing arm is provided with an upper cantilever and a lower cantilever located at the upper and lower ends of the slide seat, and the upper and lower ends of the vertical sliding rod are respectively fixed to the upper cantilever and the lower cantilever.

[0009] Furthermore, the swing rod and the lead screw are both arranged horizontally.

[0010] Furthermore, a first travel switch is provided on the bracket corresponding to the head end position of the screw rod, and a second travel switch is provided on the bracket corresponding to the tail end position of the screw rod. The first travel switch and the second travel switch are both electrically connected to the controller and the motor, so as to switch the motor between forward and reverse rotation when the screw rod nut touches the first travel switch or the second travel switch.

[0011] Furthermore, the solar cell assembly and the supporting arm are provided in plurality and correspond to each other one by one, and the upper end of each supporting arm is fixedly connected to the middle part of the lower surface of the corresponding solar cell assembly.

[0012] Furthermore, the controller is a microcomputer time-controlled switch.

[0014] Furthermore, the support comprises a front support with a lower height and a rear support with a higher height, and the lower end and the upper end of the solar cell assembly are rotatably connected to the front support and the rear support respectively through a pivot.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] Driven by the motor, the solar cell assembly of the present invention rotates once every certain period of time, thereby keeping up with the angle of rotation of the sun, so that the incident angle of sunlight irradiating the solar cell assembly is always maintained at about 90 degrees, thereby fully improving the utilization rate of solar energy. In addition, the tracking mechanism of the present invention has a simple structure, low cost, low energy consumption, and good working stability. It can realize the tracking rotation of one or more solar cell assemblies, and is flexible to use and highly practical. At the same time, the tracking process does not require manual intervention, and the operation and use are very convenient.

[0022] The present invention is further described in detail below with reference to the embodiments given in the accompanying drawings.

[0023] like Figures 1 to 5 As shown, a solar power generation device with automatic tracking function described in the present invention comprises a bracket 1, at least one solar cell assembly 2 rotatably arranged on the bracket 1, and a tracking mechanism 3 for controlling the rotation of the solar cell assembly 2 to achieve the tracking function. The tracking mechanism 3 comprises a controller 31, a motor 32, a transmission mechanism 33, a swing rod 34 and a support arm 35. The controller 31 is electrically connected to the motor 32 to control the timing of the motor 32. The motor 32 drives the swing rod 34 to swing through the transmission mechanism 33. The lower end of the support arm 35 is hinged to the swing rod 34, and the upper end of the support arm 35 is fixedly connected to the solar cell assembly 2.

[0024] Furthermore, the transmission mechanism 33 includes a screw rod 331 and a screw nut 332, the screw rod 331 is connected to the motor 32, the screw nut 332 is sleeved on the screw rod 331, and the swing rod 34 is connected to the screw nut 332 through a connecting assembly 4. As another alternative embodiment of the present invention, the transmission mechanism can also be other linear transmission mechanisms, such as a synchronous belt type transmission mechanism.

[0025] Furthermore, the connecting component 4 includes a slide seat 41 fixed on the screw nut 332 and a vertical sliding rod 42 fixed on the rocker arm 34. The vertical sliding rod 42 can be slidably inserted into the slide seat 41, so that when the screw nut 332 makes a linear motion on the screw 331, it can drive the rocker arm 34 to swing accordingly, and the swing of the rocker arm 34 drives the support arm 35 to rotate, thereby realizing the rotation of the solar cell component 2. In this process, since the vertical sliding rod 42 and the slide seat 41 are in sliding cooperation, the flexibility and smoothness of the rocker arm 34 when swinging can be ensured.

[0026] Preferably, to ensure convenient connection, the rocker arm 34 is provided with an upper cantilever 341 and a lower cantilever 342 located at the upper and lower ends of the slide seat 41, wherein the upper cantilever 341 is installed on the rocker arm 34 through a support frame 340, and the lower cantilever is directly installed on the rocker arm 34, and the upper and lower ends of the vertical sliding rod 42 are respectively fixed on the upper cantilever 341 and the lower cantilever 342.

[0027] Preferably, to simplify the structure, the rocker rod 34 and the lead screw 331 are both arranged horizontally.

[0028] Furthermore, a first travel switch 5 is provided on the bracket 1 at a position corresponding to the head end of the screw rod 331, and a second travel switch 6 is provided on the bracket 1 at a position corresponding to the tail end of the screw rod 331. Both the first travel switch 5 and the second travel switch 6 are electrically connected to the controller 31 and the motor 32, so as to switch the motor 32 between forward and reverse rotation when the screw nut 332 touches the first travel switch 5 or the second travel switch 6. Specifically, the controller 31 first controls the motor 32 to rotate forward at a fixed time, and then drives the screw nut 332 to move from the head end to the tail end of the screw rod 331, until the screw nut 332 touches the second travel switch 6, and the solar cell assembly 2 also just completes a round of rotation work of tracking the sun, at which time the motor 32 is switched to the reverse state, and then the screw nut 332 moves from the tail end to the head end of the screw rod 331 according to the control of the controller 31 and returns to the initial position of touching the first travel switch 5, at which time the motor 32 switches to the forward state, waiting for the start of the next round of tracking work.

[0029] Preferably, there are multiple solar cell assemblies 2 and multiple supporting arms 35 , and the two are in one-to-one correspondence, and the upper end of each supporting arm 35 is fixedly connected to the middle part of the lower surface of the corresponding solar cell assembly 2 .

[0030] Preferably, the controller 31 is a microcomputer time-controlled switch, and the specific structure of the microcomputer time-controlled switch is prior art, so it will not be described in detail.

[0031] Preferably, there are multiple solar cell assemblies 2, which are all arranged side by side on the bracket 1 in an inclined state, so that the utilization rate of solar energy can be further improved.

[0032] Furthermore, the support 1 includes a front support 11 with a lower height and a rear support 12 with a higher height, and the lower end and the upper end of the solar cell assembly 2 are rotatably connected to the front support 11 and the rear support 12 respectively through a pivot.

That is, all simple equivalent changes and modifications made according to the scope of the patent application and the content of the invention description of the present invention are still within the scope of the patent of the present invention.
