Description

Technical Field

[0001] The utility model relates to the technical field of solar panel transmission, in particular to a solar panel tracking control component. Background Art

[0002] In the current systems that use solar energy for photovoltaic power generation, solar water heating, etc., the installation direction of solar panels is generally fixed according to the local sunshine conditions. Therefore, most of the time, the sunlight is not completely perpendicular to the light-facing surface of the solar panel, and the utilization and conversion rate of solar energy is low. In order to improve the absorption and conversion efficiency of solar panels, some methods and technologies are used to automatically track the direction of the sun so that the sunlight is directed as vertically as possible to the solar energy.

[0003] At present, solar panels are arranged in multiple rows in parallel. In order to enable all the parallel solar panels to achieve the synchronous tracking function, the existing technology usually installs a semicircular toothed disc at the bottom of each solar panel, and then sets a transmission shaft that runs through the bottom of each solar panel. The transmission shaft is provided with a worm that meshes with the semicircular toothed discs of each solar panel. Through this worm gear structure, when the transmission shaft rotates, it will drive all the semicircular toothed discs to deflect synchronously, so that all solar panels can achieve the synchronous tracking function. However, this structure has some disadvantages: since all the toothed discs are synchronously moving, it is necessary to have a high matching accuracy between the toothed disc and the worm to ensure that the error of the deflection angle between each solar panel is small, that is, during synchronous tracking, each solar panel should theoretically have the same deflection angle, and for deflection angles with large errors, manual adjustment measures need to be taken in a timely manner. Based on this, the present application provides a solar panel tracking control component. Utility Model Content

[0004] The purpose of the utility model is to provide a solar panel tracking control assembly to solve the problems raised in the above background technology.

[0005] To achieve the above object, the utility model provides the following technical solution: A solar panel tracking control component, including a solar panel unit. The solar panel unit includes a bracket, a solar panel, a rotating shaft and a transmission shaft. The rotating shaft is horizontally rotatably installed at the top of the bracket and the solar panel is fixedly connected to the rotating shaft. Below the rotating shaft, a driven shaft and a driving shaft perpendicular to the center line of the rotating shaft are successively arranged from near to far. The driven shaft and the driving shaft are coaxially arranged. One end of the driving shaft and the driven shaft is connected by a clutch device, and the other end of the driven shaft is connected to the rotating shaft through a vertical transmission mechanism. The other end of the driving shaft is connected to a second bevel gear. The transmission shaft includes a transmission shaft I and a transmission shaft II. One end of the transmission shaft I is connected to a first bevel gear, and one end of the transmission shaft II is connected to a third bevel gear. The second bevel gear meshes with the first bevel gear and the third bevel gear at the same time. The transmission shaft of the previous solar panel unit is power-connected to the transmission shaft of the next solar panel unit.

[0006] By adopting the above technical solution: When the transmission shaft of the solar panel unit at the starting end is connected to the speed reducer, the solar panel units can be linked through the transmission shaft. For any one of the solar panel units, when the clutch device is in the engaged state and the transmission shaft I or the transmission shaft II transmits power, the driving shaft can transmit the power from the transmission shaft to the driven shaft, and drive the rotating shaft to rotate through the vertical transmission mechanism between the driven shaft and the rotating shaft, so that the solar panel deflects. When the solar panel rotates to the maximum angle, the clutch device disconnects the power transmission. At this time, the driving shaft starts to idle. Through the meshing transmission of the first, second and third bevel gears, the transmission shaft can still transmit power, and then can drive the solar panel that has not reached the maximum angle to continue to deflect, without being affected by a single solar panel. Therefore, this structure can achieve that all solar panels deflect to the maximum angle without manual adjustment, ensuring the synchronous tracking effect between the solar panel units during the next operation.

[0007] The vertical transmission mechanism includes an end face gear disc and a spur gear. The end face gear disc is fixedly connected to the rotating shaft and the end face gear disc is of a semi-circular structure. The end face gear disc is coaxially arranged with the rotating shaft. The spur gear is fixedly installed at the top end of the driven shaft, and the end face gear disc and the spur gear mesh with each other.

[0008] By adopting the above technical solution: For the end face gear disc and the spur gear, the spur gear receives the power and transmits it to the end face gear, and the end face gear drives the rotating shaft to rotate so that the solar panel deflects.

[0009] The clutch device is an electromagnetic clutch.

[0010] The top of the bracket has a bearing seat I and a bearing seat II. The bearing seat I is used to install the driving shaft, and the bearing seat II is used to install the driven shaft.

[0011] By adopting the above technical solution: The driving shaft is installed on the side of the bracket through the bearing seat I, and the driven shaft is installed on the side of the bracket through the bearing seat II to improve the reliability of the structure.

[0012] It further includes an intermediate bracket, and the transmission shaft is rotatably installed at the top of the intermediate bracket.

[0013] By adopting the above technical solution: The intermediate bracket provides support for the transmission shaft to ensure the stability of the transmission shaft during operation.

[0014] The technical effects and advantages of the present utility model:

[0015] 1. In this solution, the synchronous deflection between the solar panels can be achieved. Since there is a clutch device, the angular deflection error of a single solar panel does not need to be adjusted manually. Instead, all solar panels complete the "zero calibration" operation of the deflection angle by deflecting to the maximum angle each time, so as to obtain the best synchronous tracking effect between the solar panel units during the next operation.

[0016] 2. In this solution, the vertical transmission mechanism is provided with an end face gear disk and a spur gear. The spur gear receives power and transmits it to the end face gear, and the end face gear drives the rotating shaft to rotate, so as to deflect the solar panel. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0020] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0021] Embodiment 1

[0022] This embodiment providesFigure 2 A solar panel tracking control component as shown, which includes a solar panel 1 unit. In this embodiment, three solar panel 1 units are adopted. As Figure 1 shown, each solar panel 1 unit includes a bracket 12, a solar panel 1, a rotating shaft 2 and a transmission shaft 8. The rotating shaft 2 is horizontally rotatably installed at the top of the bracket 12 and the solar panel 1 is fixedly connected to the rotating shaft 2; below the rotating shaft 2, a driven shaft 5 and a driving shaft 6 perpendicular to the center line of the rotating shaft 2 are successively arranged from near to far, and the driven shaft 5 and the driving shaft 6 are coaxially arranged.

[0023] Furthermore, one end of the driving shaft 6 and the driven shaft 5 is connected by a clutch device 7, and the clutch device 7 is designed to engage and disengage the power transmission between the driving shaft 6 and the driven shaft 5. The other end of the driven shaft 5 is connected to the rotating shaft 2 through a vertical transmission mechanism, and the other end of the driving shaft 6 is connected to a second bevel gear 10; the transmission shaft 8 includes a transmission shaft Ⅰ 8a and a transmission shaft Ⅱ 8b. One end of the transmission shaft Ⅰ 8a is connected to a first bevel gear 9, and one end of the transmission shaft Ⅱ 8b is connected to a third bevel gear 11; the second bevel gear 10 is simultaneously meshed with the first bevel gear 9 and the third bevel gear 11; as Figure 2 shown, a speed reducer 13 is connected to the transmission shaft 8 of one of the solar panel 1 units, and then the transmission shaft 8 of the previous solar panel 1 unit is power-connected to the transmission shaft 8 of the next solar panel 1 unit.

[0024] When the clutch device 7 is in the engaged state and the transmission shaft Ⅰ 8a or the transmission shaft Ⅱ 8b transmits power, the driving shaft 6 can transmit the power from the transmission shaft 8 to the driven shaft 5, and drive the rotating shaft 2 to rotate through the vertical transmission mechanism between the driven shaft 5 and the rotating shaft 2, so that the solar panel 1 deflects. When the solar panel 1 rotates to the maximum angle, the clutch device 7 disconnects the power transmission. At this time, the driving shaft 6 starts to rotate idly. Through the meshing transmission of the first bevel gear 9, the second bevel gear 10 and the third bevel gear 11, the transmission shaft 8 can still transmit power, and then can drive the solar panel 1 that has not reached the maximum angle to continue to deflect, without being affected by a single solar panel 1. Therefore, this structure can achieve that all solar panels 1 deflect to the maximum angle without manual adjustment, ensuring the synchronous tracking effect between the solar panel 1 units during the next operation.

[0025] The vertical transmission mechanism of this embodiment includes an end face gear disc and a spur gear 4. The end face gear disc is fixedly connected to the rotating shaft 2 and the end face gear disc is of a semi-circular structure. The end face gear disc is coaxially arranged with the rotating shaft 2. The spur gear 4 is fixedly installed at the top end of the driven shaft 5, and the end face gear disc and the spur gear 4 are meshed with each other.

[0026] It can be seen that when the transmission shaft 8 of the solar panel 1 unit at the starting end is connected to the speed reducer 13, the solar panel 1 units can be linked through the transmission shaft 8. For any one of the solar panel 1 units, when the clutch device 7 is in the disengaged state, its transmission route is: transmission shaft Ⅰ 8a - first bevel gear 9 - second bevel gear 10 - third bevel gear 11 - transmission shaft Ⅱ 8b. When the clutch device 7 is in the engaged state, its main transmission route is: second bevel gear 10 - driving shaft 6 - driven shaft 5 - spur gear 4 - face gear disc - rotating shaft 2. Among them, the spur gear 4 receives power and transmits it to the face gear 3, and the face gear 3 drives the rotating shaft 2 to rotate so as to deflect the solar panel 1.

[0027] In this embodiment, the clutch device 7 is an electromagnetic clutch.

[0028] To describe further, there is also an angle sensor and a controller in this embodiment. The angle sensor is installed on the rotating shaft 2 to detect the deflection angle of the rotating shaft 2, and both the electromagnetic clutch and the angle sensor are connected to the controller. When the angle sensor detects that the rotation angle of the solar panel 1 reaches the maximum and feeds back to the controller, the controller immediately issues an instruction to disconnect the power of the electromagnetic clutch. On the contrary, when the solar panel 1 unit starts to work, the controller issues an instruction to engage the electromagnetic clutch to ensure that the solar panel 1 deflects normally.

[0029] Specifically, the top of the bracket 12 has a bearing seat Ⅰ 15 and a bearing seat Ⅱ 16. The bearing seat Ⅰ 15 is used to install the driving shaft 6, and the bearing seat Ⅱ 16 is used to install the driven shaft 5. The driving shaft 6 is installed on the side of the bracket 12 through the bearing seat Ⅰ 15, and the driven shaft 5 is installed on the side of the bracket 12 through the bearing seat Ⅱ 16 to improve the reliability of the structure.

[0030] Further, in order to ensure the stability of the transmission shaft 8 during operation, an intermediate bracket 14 is also provided. The transmission shaft 8 is rotatably installed at the top of the intermediate bracket 14, and the intermediate bracket 14 provides support for the transmission shaft 8.

[0031] In summary, a solar panel tracking control component in the present solution can achieve synchronous deflection among the solar panels 1. Due to the presence of the clutch device 7, the angular deflection error of a single solar panel 1 does not need to be manually adjusted. Instead, all the solar panels 1 complete the "zero calibration" operation of the deflection angle by deflecting to the maximum angle each time, so as to obtain the best synchronous tracking effect among the solar panel units 1 during the next operation. Finally, it should be noted that the above is only the preferred embodiment of the present utility model and is not used to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
