Description

Technical Field

[0001] The present application relates to the field of solar power generation technology, and in particular to a solar tracking system, a solar tracking device and a driving component thereof. Background Art

[0002] A solar tracking device is a commonly used device in the field of solar photovoltaic power generation. It can adjust the angle of the solar panels so that the panels are directly exposed to sunlight at any time of the day to improve power generation efficiency.

[0003] Solar tracking devices are typically installed in open-air environments, where they are inevitably subject to wind, which can affect their stability. Especially during severe weather conditions such as strong winds and heavy rain, the devices struggle to maintain their sheltered position, making them susceptible to damage and causing significant losses. Furthermore, the mechanical structures used to adjust the solar panel angle in existing solar tracking devices are complex and difficult to manufacture, resulting in prohibitively high costs for adjusting the angle of the solar tracker.

[0004] Therefore, how to improve the stability of the solar tracking device as much as possible at a low cost so that it can stably maintain a windproof state in severe weather is an urgent problem to be solved by ordinary technicians in this field. Utility Model Content

[0005] The purpose of the present application is to provide a solar tracking system, a solar tracking device and a drive assembly thereof. The drive assembly has a self-locking function, which can realize the self-locking of the solar tracking device. In this way, when the solar tracking device is in a windproof state, the drive assembly can limit the rotation of the solar panel under the action of wind, so that the solar tracking device can be stably maintained in the windproof state.

[0006] The technical solutions provided in this application are as follows:

[0007] A driving assembly of a solar tracking device, characterized by comprising:

[0008] The driving bracket includes a first fixing portion, a top end of which is provided with a rotating mechanism for mounting a solar panel;

[0009] A transmission mechanism, comprising a rotating member and a guide member;

[0010] A driving mechanism, mounted on the rotating mechanism, having a power output end;

[0011] The rotating member is drivingly connected to the driving mechanism, and includes a fixing member for docking with the power output end and a tooth column provided on the fixing member, wherein the number of the tooth columns is two; the guide member is mounted on the first fixing portion, and the upper end surface or the lower end surface of the guide member is in an arc shape and is provided with a plurality of grooves that can be selectively engaged with the tooth columns;

[0012] When the driving mechanism drives the rotating member to rotate, the tooth column and the groove cooperate to drive the rotating member to move along the upper end surface of the guide member or the lower end surface of the guide member, thereby driving the driving mechanism and the rotating mechanism to rotate; when the driving mechanism stops running and the line connecting the two tooth columns is distributed along the tangent direction of the upper end surface or the lower end surface of the guide member, the guide member and the rotating member are locked in the self-locking position.

[0013] In some embodiments, the driving mechanism is connected to the rotating mechanism via a connecting arm, and there is one rotating member and one guiding member, which are respectively arranged on a side where the connecting arm and the first fixing portion are close to each other.

[0014] In some embodiments, the first fixing portion includes a first column and a second column;

[0015] The second column is arranged on the top of the first column and is located on a side of the first column away from the connecting arm. The guide member is arranged on the second column.

[0016] In some embodiments, the driving mechanism includes a reduction motor installed at one end of the connecting arm away from the rotating mechanism, the reduction motor has a power output shaft, and one end of the power output shaft forms the power output end; or,

[0017] The driving mechanism includes a worm wheel, a worm and a rotating motor. The connecting arm is a hollow structure. The worm wheel and the worm are connected and installed inside the connecting arm. The rotating motor is located outside the connecting arm and is used to drive the worm to rotate, thereby driving the worm wheel to rotate around its own axis. One end of the worm wheel in the direction of its own axis forms the power output end, and the connecting arm is provided with an avoidance hole corresponding to the power output end for the power output end to connect with the rotating part. The driving mechanism and the connecting arm together form a reducer.

[0018] In some embodiments, the guide member has a wind-shielding portion;

[0019] The guide member is provided with a gasket or a pad in the wind shelter portion to increase the strength of the guide member in the wind shelter portion; or the guide member is provided with a notch in the wind shelter portion, and a gasket or a pad is installed in the notch, and the material strength of the gasket and the pad is greater than the material strength of the guide member to increase the strength of the guide member in the wind shelter portion.

[0020] In some embodiments, the guide member is provided with limiting portions at both ends of its upper end face or lower end face in the arc length direction, so as to limit the range of movement of the rotating member along the upper end face or lower end face of the guide member, thereby realizing mechanical limiting.

[0021] The present application also provides a solar tracking device, comprising:

[0022] A fixed bracket and a driving assembly of the solar tracking device provided by any of the above embodiments;

[0023] The fixing bracket includes a plurality of second fixing parts, and the first fixing part and the plurality of second fixing parts are arranged along a straight line; a main beam is rotatably provided through the top ends of the first fixing part and the plurality of second fixing parts to form the rotating mechanism.

[0024] In some embodiments, there are multiple drive assemblies, and the drive mechanisms in the multiple drive assemblies are all controlled by the same control loop.

[0025] In some embodiments, the control circuit includes an electrical linkage controller for controlling the synchronous operation of the plurality of driving mechanisms.

[0026] The present application further provides a solar tracking system, comprising:

[0027] At least two rows of solar tracking devices, each row of the solar tracking devices including a rotating mechanism and a plurality of spaced-apart second fixing portions, the rotating mechanism being disposed on top of the plurality of second fixing portions for mounting solar panels and driving the solar panels to rotate;

[0028] One row of the solar tracking devices is a main row tracking device, the main row tracking device is the solar tracking device provided in any of the above embodiments, and the driving mechanism on the main row tracking device is connected to the rotating mechanism on the main row tracking device via a connecting arm; the remaining solar tracking devices are auxiliary row tracking devices, the rotating mechanism on the auxiliary row tracking device is connected to a swing arm, and the connecting arm and the swing arm are connected by a connecting rod;

[0029] When the driving mechanism drives the rotating part to rotate, the rotating part drives the driving mechanism and the connecting arm to move along the upper end surface of the guide part or the lower end surface of the guide part, thereby driving the rotating mechanism on the main row tracking device to rotate, and the connecting arm drives the swing arm to swing through the connecting rod, thereby driving the rotating mechanism on the secondary row tracking device to rotate.

[0030] The technical effects of this application are:

[0031] 1. In the present application, the driving mechanism is used to drive the rotating member to rotate. The rotating member can move along the arc surface (upper end surface or lower end surface) of the guide member by means of a number of grooves provided on the guide member, thereby driving the driving mechanism and the rotating mechanism to rotate and realize the rotation of the solar panel. The rotating member and the guide member can achieve self-locking. When the line connecting the two tooth columns of the rotating member is distributed along the tangent direction of the arc surface of the guide member, the rotating member and the guide member are in the self-locking position. At this time, if the driving mechanism does not drive the rotating member to continue rotating, the rotating member and the guide member will be locked in the self-locking position. Even if the solar panel tends to rotate due to the action of wind, the rotating member will not continue to move along the arc surface of the guide member, thereby limiting the rotation of the solar panel and helping the solar tracking device to maintain a stable windproof state.

[0032] 2. In the present application, the second column is eccentrically arranged relative to the first column, and is located on the side of the first column away from the connecting arm, and the guide member is arranged on the side of the second column facing the connecting arm. Because the rotating mechanism is mainly driven by the driving mechanism during the rotation process, the driving mechanism is located between the second column and the connecting arm, and the eccentric arrangement of the second column helps the driving mechanism to be more centered relative to the first fixed part, which is more conducive to the force and balance of the rotating mechanism. Therefore, the driving torque of the driving assembly provided by the present application is large but the vibration is small, and the first fixed part is not easily damaged or twisted off under the action of strong winds. The structural arrangement is more reasonable and practical.

[0033] 3. In the solar tracking system provided by the present application and equipped with multiple rows of solar tracking devices, the main row tracking device includes the drive assembly provided by the present application. Because during the rotation of the rotating mechanism, the drive mechanism drives the connecting arm to swing and thereby drives the rotating mechanism to rotate, the present application utilizes a swinging connecting arm structure to provide a swing arm on the rotating mechanism of the secondary row tracking device. The connecting arm drives the swing arm to swing together via a connecting rod, thereby driving the rotating mechanism on the secondary row tracking device to rotate, thereby achieving synchronous angle adjustment of multiple rows of solar tracking devices. Moreover, the second swing arm driven by the first swing arm in the present application directly acts on the rotating mechanism, resulting in a more streamlined structure and low cost.

[0046] In the following description, specific details such as specific system structures and technologies are provided for illustration rather than limitation to facilitate a thorough understanding of the embodiments of the present application. However, it should be clear to those skilled in the art that the present application may be implemented in other embodiments without these specific details. In other cases, detailed descriptions of well-known systems, devices, circuits, and methods are omitted to avoid obstructing the description of the present application with unnecessary details.

Obviously, the drawings described below are only some embodiments of the present application. For those skilled in the art, other drawings and other implementation methods can be obtained based on these drawings without inventive work.

Those skilled in the art will understand the specific meanings of the above terms in this application in specific circumstances.

[0050] In the embodiments shown in the drawings, directional indications (such as up, down, left, right, front, and back, etc.) are not absolute but relative when describing the structure and movement of each component, and are not used to limit the direction of the product in actual use.

[0051] In addition, in the description of this application, ordinal numbers, such as "first", "second", etc., are only used to distinguish and describe related objects, and cannot be understood as indicating or implying the relative importance or order between related objects.

[0052] See also Figures 1 to 3The present application provides a drive assembly for a solar tracking device, comprising a drive bracket, a transmission mechanism, and a drive mechanism 140. The drive bracket further comprises a first fixed portion 110, with a rotating mechanism mounted on the top of the first fixed portion 110. The transmission mechanism further comprises a guide member 120 and a rotating member 130. The drive mechanism 140 is mounted on the rotating mechanism, and the guide member 120 is mounted on the first fixed portion 110. The upper end surface or the lower end surface of the guide member 120 is arc-shaped and provided with a plurality of first guide structures. The rotating member 130 is drivingly connected to the drive mechanism 140 and provided with a second guide structure. When the drive mechanism 140 rotates the rotating member 130, the first and second guide structures cooperate to drive the rotating member 130 along the upper end surface or the lower end surface of the guide member 120, thereby driving the drive mechanism 140 and the rotating mechanism to rotate. The rotating mechanism can be used to mount solar panels, and the angle of the solar panels can be adjusted by changing the angle of the rotating mechanism.

[0053] A self-locking structure should be provided between the first and second guide structures to lock the guide member 120 and the rotating member 130 in the self-locking position. This allows the rotating mechanism to remain stable in a wind-sheltered position when wind speeds are high, thereby limiting oscillation of the solar panel caused by excessive wind, improving the stability of the solar tracking device, and minimizing losses.

[0054] In a specific embodiment, see Figure 3 and Figure 4 The drive mechanism 140 has a power output terminal 203. The rotating member 130 includes a fixed member 131 and two toothed posts 132 disposed on the fixed member 131. The fixed member 131 is used to connect to the power output terminal 403. There are two toothed posts 132. Meanwhile, the guide member 120 (on its upper or lower end surface) is provided with a plurality of grooves 121 that can selectively engage with the toothed posts 132. In this case, the toothed posts 132 serve as the aforementioned second guide structure, and the grooves 121 serve as the aforementioned first guide structure.

[0055] When the rotating member 130 rotates under the drive mechanism 140, one tooth post 132 on the rotating member 130 leaves the groove 121 in which it was originally located and enters the other groove 121 along the direction of rotation. This allows the second rotating member to move along the arc-shaped lower end surface of the guide member 120, thereby achieving rotation of the rotating mechanism. Furthermore, since there are two tooth posts 132, they can be arranged symmetrically around the center. This allows the transmission mechanism provided by this embodiment to have a self-locking function. Specifically, when the line connecting the two tooth posts 132 is tangential to the upper or lower end surface of the guide member 120, the guide member 120 and the rotating member 130 are locked in the self-locking position, achieving self-locking.

[0056] Specifically, in the windproof state, the solar panels are arranged in a generally horizontal direction, and the line connecting the two tooth posts 132 is preferably arranged in the horizontal direction. In this case, the two tooth posts 132 are respectively engaged in two adjacent grooves 121. If the rotating mechanism tends to rotate due to the solar panel being driven by wind, the two tooth posts 132 and the protrusions formed between the adjacent grooves 121 in which the tooth posts 132 are engaged will restrain each other, thereby limiting the rotation mechanism from driving the rotating member 130 to move in turn. This ensures that the solar panel remains relatively stable under the influence of wind, which is highly practical.

[0057] This embodiment achieves transmission connection and self-locking between the rotating member 130 and the guide member 120 by only providing two gear columns 132. It has a simple structure and low cost, successfully improves the stability of the solar tracking device as much as possible at a low cost, and has strong practicality.

[0058] Preferably, the guide member 120 is provided with a limiting portion (not shown) at both ends of its own arc surface (upper end surface or lower end surface) in the arc length direction, so as to limit the range of movement of the rotating member 130 when it moves along the arc surface of the guide member 120, thereby realizing mechanical limiting and preventing the rotating member 130 from separating from the guide member 120.

[0059] Of course, in actual production, the guide member 120 and the rotating member 130 can also be configured as a Maltese wheel structure. The Maltese wheel consists of a dial with a round pin and a sheave with radial grooves. Both the dial and the sheave have locking arc grooves: a concave arc on the sheave and a convex arc on the dial, respectively. These arc grooves both function as a locking mechanism. Specifically, when the dial's pin has not yet entered the sheave, the concave arc of the sheave is caught by the dial's convex arc, causing the sheave to remain stationary. When the dial's pin begins to enter the sheave's radial groove, the locking arc is released, allowing the pin to drive the sheave to rotate. When the pin leaves the sheave's radial groove, the other concave arc of the sheave is again locked by the dial's convex arc, causing the sheave to remain stationary. This cycle repeats. In this embodiment, by configuring the rotating member 130 as a dial structure and the guide member 120 as a sheave, the locking arc grooves thereon can achieve self-locking of the transmission mechanism. This will not be elaborated upon here, as all of these are within the scope of protection of this application.

[0060] In one example embodiment, see Figure 1 and Figure 2 The driving mechanism 140 can be connected to the rotating mechanism through a connecting arm 150. When the driving mechanism 140 moves under the drive of the rotating member 130, the connecting arm 150 can form a structure similar to a swing arm. Through the connecting arm 150, the solar tracking device provided in this embodiment can drive the rotating mechanism on other solar tracking devices to rotate.

[0061] Specifically, see Figure 1 and Figure 7In this embodiment, the connecting arm 150 serves as the driving arm, and a swing arm 170 is provided on the rotating mechanism of the other solar tracking devices. The connecting arm 150 and the swing arm 170 are connected by a connecting rod 180. Thus, when the connecting arm 150 is driven by the rotating member 130 to swing, the swing arm 170 rotates along with the connecting arm 150, thereby driving the rotating mechanisms of the other solar tracking devices to rotate, achieving coordinated angle adjustment of multiple rows of solar tracking devices and achieving high structural utilization.

[0062] Specifically, there is one rotating member 130 and one guiding member 120, each located on the side of the connecting arm 150 that is adjacent to the first fixing portion 110. In this embodiment, by locating the driving mechanism 140 between the connecting arm 150 and the first fixing portion 110, forces are balanced across the driving mechanism 140, allowing it to move more stably under the influence of the rotating member 130. This, in turn, drives the rotating mechanism to rotate stably, resulting in better angle adjustment.

[0063] As a preference, see Figure 2 The first fixing portion 110 includes a first column 111 and a second column 112. The second column 112 is disposed on the top of the first column 111 and is located on a side of the first column 111 away from the connecting arm 150. At this time, the guide member 120 is disposed on the second column 112.

[0064] This embodiment is more conducive to setting the driving mechanism 140 at the center or near the center of the first column 111 by eccentrically setting the second column 112 relative to the first column 111. Moreover, during the rotation process, the rotating mechanism is mainly driven by the driving mechanism 140. The driving mechanism 140 is located at the center or near the center of the first column 111, which can make the driving force received by the rotating mechanism relatively centered relative to the first fixed part 110. The forces received by the rotating mechanism and the first fixed part 110 are more balanced, which is conducive to improving the rotational stability of the rotating mechanism and the load-bearing capacity of the first fixed part 110. Therefore, the driving torque of the driving assembly provided by the present application is large but the vibration is small. The first fixed part 110 is not easily damaged or twisted off under the action of strong winds. The structural setting is more reasonable and practical.

[0065] In all the above embodiments, see Figure 1 and Figure 3The guide member 120 can be constructed in the form of an arc-shaped plate, saving material costs. The guide member 120 preferably has an arc-shaped lower end surface and is provided with the aforementioned first guide structure. To enhance the stability of the solar tracking device and the structural strength of the drive assembly, a connector 122 can be provided to connect the two ends of the guide member 120 along the arc length. This connector 122 can also be used to connect the first fixing portion 110, further stabilizing the connection between the guide member 120 and the first fixing portion 110. This also improves the rotational stability of the rotating mechanism and the load-bearing capacity of the first fixing portion 110.

[0066] Of course, in actual production, the guide member 120 can also be a fan-shaped plate structure. Compared with the arc-shaped plate structure, although the material cost is increased, the structural strength is also improved. Different forms of guide members 120 can be selected according to actual needs.

[0067] Preferably, in all the above embodiments, the guide member 120 should have a wind-shielded portion, that is, when the rotating mechanism is in the wind-shielded state, the guide member 120 is docked with the portion of the rotating member 130, and a gasket or pad 123 should be added to the portion to perform local structural reinforcement on the wind-shielded portion to improve the structural strength of the wind-shielded portion, thereby improving the wind resistance of the solar tracking device in the wind-shielded state.

[0068] For example, see Figure 3 A pad 123 is provided in the windproof portion on the side of the guide member 120 facing the first fixed part 110. At this time, the pad 123 can also be used to dock with the first fixed part 110 to strengthen the connection strength between the guide member 120 and the first fixed part 110, thereby improving the rotational stability of the rotating mechanism and the load-bearing capacity of the first fixed part 110.

[0069] Alternatively, the position of the guide member 120 corresponding to the wind shelter portion may be hollowed out to form a gap, and then filled with a gasket or block of equal thickness and greater mass to increase the material strength of the wind shelter portion, thereby improving the wind resistance of the solar tracking device in the wind shelter state. This is not limited here and is within the scope of protection of this application.

[0070] Further, referring to 1, in all the above embodiments, the driving mechanism 140 preferably includes a reduction motor, which is directly mounted on the end of the connecting arm 150 away from the rotating mechanism, and the reduction motor has a power output shaft, and the power output shaft forms a power output end 203 at one end in its own axial direction to connect to the rotating member 130. The reduction motor is preferably a worm gear reducer.

[0071] In one example embodiment, see Figure 5 and Figure 6, the drive mechanism 140 can be directly integrated into the connecting arm 150. In this case, the connecting arm 150 has a hollow structure and serves as the housing of the drive mechanism 140. Specifically, the drive mechanism includes a worm gear 141, a worm 142, and a rotary motor. The worm gear 141 and the worm 142 are connected in a transmission manner and installed inside the connecting arm 150. In this case, an opening 151 is provided on one side of the connecting arm 150. The power output shaft of the rotary motor passes through the opening 151 and is connected to the worm 142. In this way, the rotary motor can drive the worm 142 to rotate, thereby driving the worm gear 141 to rotate.

[0072] In this embodiment, one end of the worm gear 141 in the direction of the rotation axis forms the power output end 203, and the connecting arm 150 has an avoidance hole 152 corresponding to the power output end, allowing the power output end 203 to connect with the rotating member 130. In this case, the driving mechanism 140 and the connecting arm 150 together form a speed reducer.

[0073] See also Figure 1 and Figure 7 This application also provides a solar tracking device, comprising a fixed bracket and a drive assembly of the solar tracking device provided by any of the above-described embodiments. The fixed bracket includes a plurality of second fixing portions 160. Bearings 201 are provided at the tops of the first fixing portion 110 and the plurality of second fixing portions 160, and the first fixing portion 110 and the plurality of second fixing portions 160 are arranged in a straight line. A main beam 202 is rotatably mounted through the bearings 201 provided on the first fixing portion 110 and the plurality of second fixing portions 160, forming a rotating mechanism. The main beam 202 is provided with a plurality of evenly spaced purlins to secure the solar panels.

[0074] In this embodiment, the structure of the second fixing portion 160 may be the same as or different from the structure of the first fixing portion 110 .

[0075] In one exemplary embodiment, multiple drive assemblies can be used to drive the rotating mechanism, enabling multi-point actuation of the solar tracking device. Multi-point actuation not only makes the support structure more stable during operation, but also provides more support points, making the support structure more rigid and preventing damage caused by wind-induced resonance. Furthermore, due to the greater rigidity of the support structure, the number of pile foundations (such as the second fixing portion 160 in this application) can be reduced compared to a single-point actuation structure, thereby reducing costs.

[0076] In this embodiment, multiple drive assemblies should be driven and operated synchronously. Therefore, the drive mechanisms 140 in the multiple drive assemblies should all be controlled by the same control circuit. This control circuit may specifically include an electrical linkage controller for controlling the synchronous operation of the multiple drive mechanisms 140, thereby achieving electrical linkage. For example, the electrical linkage controller obtains operating information of the drive mechanisms 140 and, based on this information, adjusts the power output of each drive mechanism 140 to ensure synchronous operation.

[0077] See also Figure 7 This application also provides a solar tracking system comprising at least two rows of solar tracking devices, one of which is equipped with a drive assembly, such as the drive assembly provided in any of the aforementioned embodiments. For ease of description, the solar tracking device equipped with the drive assembly is referred to as the primary row of tracking devices 101, and the remaining solar tracking devices are referred to as the secondary row of tracking devices 102.

[0078] Specifically, both the primary and secondary tracker rows 101 and 102 include several spaced-apart second fixing portions 160, the tops of which are suitable for mounting a rotating mechanism. The rotating mechanism on the primary tracker row is connected to the drive mechanism 140 via a connecting arm 150, while the rotating mechanism on the secondary tracker row is connected to a swing arm 170, which is connected to the swing arm 170 via a connecting rod 180. As the connecting arm 150 swings under the influence of the rotating member, the swing arm 170 rotates with it, thereby driving the rotating mechanisms on the other solar trackers, achieving coordinated angular adjustment of multiple rows of solar trackers.

[0079] Compared to conventional methods of synchronously adjusting the angles of multiple rows of solar tracking devices using ropes, the solar tracking system provided in this embodiment utilizes a swinging connecting arm 150 on the main row of tracking devices 101 and a separate connecting rod 180 to achieve synchronous adjustment, resulting in greater structural stability, improved wind resistance, and higher structural utilization. Furthermore, the connecting rod 180 is less susceptible to deformation, minimizing angular deviations between multiple rows of solar tracking devices, and achieving high adjustment precision. Furthermore, the swinging arm 170 driven by the connecting arm 150 in this embodiment acts directly on the rotating mechanism, whereas synchronously adjusting the angles of multiple rows of solar tracking devices using ropes requires the installation of multiple transmission structures to drive the rotating mechanism. This demonstrates that the solar tracking system provided in this embodiment is more streamlined and cost-effective.

[0080] In actual production, considering that the second fixing portion 160 on the secondary row tracking device 102 provided in this embodiment needs to bear a relatively small weight, the second fixing portion 160 may be a hollow structure to reduce material costs.

[0081] In the above embodiments, the description of each embodiment has its own focus. For parts that are not described or recorded in detail in a certain embodiment, reference can be made to the relevant description of other embodiments.

[0082] It should be noted that the above embodiments can be freely combined as needed. The above are only preferred implementations of the present application. It should be noted that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present application, and these improvements and modifications should also be considered as the scope of protection of the present application.
