Description

Technical Field

[0001] This invention relates to the field of photovoltaic adjustment device technology, and more specifically to a remote tilt angle adjustment device for photovoltaic power generation. Background Technology

[0002] Photovoltaic power generation is a technology that directly converts light energy into electrical energy using the photovoltaic effect at semiconductor interfaces. As an important method of utilizing clean and renewable energy, it plays an increasingly important role in the transformation of the energy structure. The photoelectric conversion efficiency is highest when sunlight shines perpendicularly onto the surface of a photovoltaic panel. Therefore, to maximize the power generation efficiency of photovoltaic panels, the tilt angle and orientation of the panels need to be adjusted in real time according to the changing position of the sun, ensuring that the panels are always facing the sun.

[0003] The adjustment devices for photovoltaic panels currently still have the following problems: 1. To improve the power generation efficiency of photovoltaic panels, multiple drive structures are usually set up to improve the efficiency of tracking the sun. However, in windy conditions, the impact of the wind directly acts on multiple drive structures. Since the drive structures have a precision transmission structure inside, they are difficult to withstand the impact of large wind forces, which can easily lead to reduced accuracy, shaking, displacement or even damage of the drive components, affecting the operational stability and service life of photovoltaic equipment.

[0004] 2. Since photovoltaic panels are installed in remote areas, it is inconvenient to fix them manually. Even if a fixing device that can be remotely controlled is installed, the photovoltaic panels will stop at different positions as they move to track the sun, which can easily lead to unstable clamping and fixing, resulting in locking failure or unstable locking, and affecting the fixing effect of the fixing device on the photovoltaic panels.

[0005] 3. In existing photovoltaic tilt adjustment devices, multiple photovoltaic panels are arranged side by side on the same plane, resulting in a large windward area. External wind forces act directly on the photovoltaic panels, leading to concentrated wind pressure and high wind resistance. This results in large overturning moments and torques acting on the frame, shaft, drive mechanism, and column, which can easily cause strong winds to overturn, bend the support, or damage the photovoltaic panels, affecting the stability of the photovoltaic panels and the tilt adjustment device.

[0006] Therefore, it is necessary to propose a remote tilt adjustment device for photovoltaic power generation to solve the above problems. Summary of the Invention

[0010] Preferably, the engagement assembly includes a fixed disk, on one side of which are circumferentially distributed spring pins facing the protrusion, and on the other side of the fixed disk is an external drive structure that pushes the fixed disk toward the protrusion.

[0011] Preferably, a first ring frame is slidably connected in the first working cavity, and a second ring frame is slidably connected in the second working cavity. A fixed plate is connected inside both the first and second ring frames. A connecting rod is rotatably connected inside the locking bracket. A first sliding groove is provided at one end of the connecting rod. A sliding pin located in the first sliding groove is installed on one side of the first ring frame. An arc-shaped part is provided at the other end of the connecting rod. Second sliding grooves are provided on both sides of the arc-shaped part. A sliding pin located in the second sliding groove is installed on the outer wall of the second ring frame.

[0012] Preferably, the first ring frame and the first working chamber are connected by a spring, a first electromagnet is installed at the bottom of the first working chamber, a ferromagnetic component that cooperates with the first electromagnet is installed at the bottom of the first ring frame, and an unlocking component for fixing the first ring frame is provided on the side wall of the first working chamber.

[0013] Preferably, a cavity is formed on the side wall of the first working chamber, and the unlocking component includes a pin slidably connected in the cavity. The pin and the cavity are connected by a spring. The end of the pin facing the first ring frame is provided with an upward-sloping surface. A groove is formed on the side wall of the first ring frame to cooperate with the pin.

[0016] Preferably, a push-pull plate is rotatably connected between two adjacent movable rods, and the lifting assembly includes an electric telescopic rod rotatably connected to a fixed bracket.

[0017] Preferably, the side of the second ring frame away from the fixed plate is connected to an optical axis that passes through the locking bracket, and the second ring frame and the second working cavity are connected by a spring.

[0018] As having the same inventive concept as the above-described technical solution, this invention also seeks protection. Compared with existing known technologies, the technical solution provided by this invention has the following significant advantages: 1. This invention, by setting up a locking bracket and internal first and second locking components, allows the locking bracket to be simultaneously connected to the column and crossbar in windy conditions. This forms a unified structure with the column, locking bracket, and crossbar, absorbing the impact of airflow rather than directly acting on the horizontal and vertical drive components. This avoids the influence of external airflow on the stability of the drive structure, improving the wind resistance and overall structural stability of the photovoltaic equipment in windy environments. It also enables adjustment of the photovoltaic panel tilt angle in windless or weak wind conditions, improving power generation efficiency; and provides locking in windy conditions, enhancing overall wind resistance and preventing damage to the tilt adjustment structure.

[0019] 2. This invention, through the setting of a meshing structure in which spring top pins cooperate with protrusions, with the spring top pins evenly distributed around the circumference of the fixed plate, achieves reliable meshing and locking at any tilt angle when the fixed plate contacts the positioning plate, solving the problem that the fixed angle meshing assembly cannot effectively mesh when the stopping angle of the adjusting frame and the crossbar is not fixed; at the same time, with the cooperation of a remote control device, the meshing and disengagement can be remotely controlled, improving the convenience of control, thereby realizing automatic locking and tilt angle adjustment.

[0020] 3. This invention, by setting a movable support and guide assembly inside the photovoltaic support structure, drives the movable support to extend outward along the guide rod in windy conditions, creating staggered airflow channels between adjacent photovoltaic panels. External airflow passes through the gaps between the photovoltaic panels instead of impacting the panel surface directly, effectively reducing overall wind resistance and wind pressure concentration. This also reduces the overturning moment and torque acting on the frame, pivot, drive mechanism, and columns, preventing strong winds from overturning, bending the support structure, or damaging the photovoltaic panels. Simultaneously, the electric telescopic rod drives the push-pull plate to move the entire row of L-shaped panels in tandem, achieving synchronous outward extension of the entire row of photovoltaic panels with intermittent drive, ensuring the consistency of the airflow channels.

[0023] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only for explaining the invention and are not intended to limit the invention; that is, the described embodiments are merely some embodiments of the invention, and not all embodiments. The components of the embodiments of the invention described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0024] The conventional components and key load-bearing components in this case are selected in accordance with standards in terms of material selection, heat treatment process and structural dimensions to ensure that they have sufficient strength, stiffness and fatigue resistance under rated load and expected working conditions. These are all conventional design considerations well known to those skilled in the art.

[0025] Depend on Figures 1 to 6 The system includes a column 101, a photovoltaic support 102, and a crossbar 103. In one embodiment, the column 101 and crossbar 103 are hollow, facilitating the internal cabling of the equipment and reducing production costs and equipment weight. An adjustment frame 104 is located above the column 101. The adjustment frame 104 and the column 101 are connected via a horizontal drive assembly, which drives the adjustment frame 104 to move left and right, facilitating angle adjustment. The adjustment frame 104 and the crossbar 103 are connected via a vertical drive assembly, which drives the crossbar 103 to rotate horizontally, facilitating tilt angle adjustment towards the sun. The horizontal and vertical drive assemblies consist of a motor, a reduction gear, and a worm gear, used to drive the entire system for angle adjustment. This is a mature existing structure and will not be described in detail here. The drive structure can adjust not only the vertical tilt angle but also the horizontal angle, facilitating movement in the direction of the sun and improving power generation efficiency. When not in use, the photovoltaic panel 110 can remain vertical, reducing the accumulation of dust, fallen leaves, and other debris on it. At the same time, rainwater can quickly wash the surface of the panel, improving its cleaning ability.

[0026] When used in outdoor locations, the photovoltaic panel 110, facing the sun, has a certain area, and external wind forces will directly act on the photovoltaic panel 110, affecting its stability. A locking bracket 105 is rotatably connected to the top of the outer wall of the column 101. The other end of the locking bracket 105 is rotatably connected to the crossbar 103, and the locking bracket 105 rotates with the crossbar 103, forming an L-shape. One end of the locking bracket 105 has a first working cavity 106 fitted onto the outside of the column 101, and the other end has a second working cavity 107 fitted onto the outer wall of the crossbar 103. A first locking component is located in the first working cavity 106, which fixes the locking bracket 105 to the outer wall of the column 101, thus securing the locking bracket 105 to the column 101. A second locking component is located in the second working cavity 107, which fixes the locking bracket 105 to the outer wall of the crossbar 103. The column 101 and the crossbar 103 are connected together by the locking bracket 105. When subjected to wind impact, the impact force will act on the locking bracket 105, preventing the drive components from being affected by the wind and improving the overall stability. This also prevents external airflow from impacting the photovoltaic equipment and affecting the stability of the horizontal and vertical drive components. Because multiple photovoltaic panels 110 are arranged side by side, their windward area is large, which can obstruct airflow and affect its passage. The two ends of the crossbar 103 are connected to the photovoltaic support 102 via fixed brackets 108, serving a connecting function. The photovoltaic support 102 has equally spaced movable brackets 109 inside, on which photovoltaic panels 110 are mounted. The movable brackets 109 are equipped with guide components, extending outwards. When the photovoltaic panels 110 extend outwards through the movable brackets 109, the gap between adjacent photovoltaic panels 110 increases, improving airflow and reducing the impact of airflow on the photovoltaic panels 110 and the drive structure. The fixed brackets 108 are equipped with lifting components that drive the moving components.

[0027] During use, the impact of wind force acts directly on the horizontal and vertical drive components through the frame structure, easily affecting the stability of the drive structure. A structure is needed to connect the upright 101 and crossbar 103 to the locking bracket 105 to improve wind resistance and prevent excessive wind from affecting the overall structural stability. The following provides a structure for connecting the upright 101 and crossbar 103 to the locking bracket 105: Specifically, the first locking component includes a first positioning disc 201 located within the first working chamber 106, connected to the outer wall of the upright 101, and its position is fixed. The second locking component includes a second positioning disc 202 located within the second working chamber 107, connected to the outer wall of the crossbar 103, and rotating with the crossbar 103. Both the first positioning disk 201 and the second positioning disk 202 have a protrusion 203 on one side. The first working cavity 106 and the second working cavity 107 are slidably connected to an engagement assembly. The engagement assembly has a toothed structure that engages with the protrusion 203, forming a fixed connection. When the engagement assembly engages with the first positioning disk 201 or the second positioning disk 202, it can only slide axially and cannot rotate. Therefore, the locking bracket 105 can be connected to the column 101 or the crossbar 103 to form a single unit, improving stability.

[0028] Since the stopping angles of the adjusting bracket 104 and the crossbar 103 are not fixed and can be arbitrary, a fixed-angle engagement assembly would affect the engagement effect with the first positioning plate 201 or the second positioning plate 202. The following provides a structure that can engage at any angle: Specifically, the engagement assembly includes a fixed plate 204, on one side of which are evenly distributed circumferential spring pins 205. Each spring pin 205 consists of a spring, a pin, and a mounting housing. Under the action of the spring, the pin extends outward; this is a well-established existing structure and will not be elaborated further here. The spring pins 205 are positioned towards the protrusion 203. When the fixed plate 204 contacts the first positioning plate 201, the protrusion 203 presses the corresponding spring pins 205 into the fixed plate 204. Spring pins 205 not blocked by the protrusion 203 extend outward, and at this time, the side of the spring pin 205 contacts the side of the protrusion 203, thus limiting rotation. The fixed disk 204 is connected to an external driving structure on the other side. The driving structure pushes the fixed disk 204 toward the protrusion 203, thereby completing the contact connection between the meshing component and the first positioning disk 201 or the second positioning disk 202.

[0029] Since the first positioning plate 201 and the second positioning plate 202 are perpendicular to each other, when a strong wind is detected or an environment of strong wind is about to be encountered, it is necessary to simultaneously connect and fix the first positioning plate 201 and the second positioning plate 202 to improve overall stability. The following provides a structure for simultaneously controlling the connection and fixation of the two structures: Specifically, a first ring frame 301 is slidably connected within the first working cavity 106, allowing the first ring frame 301 to move only axially. In one embodiment, the first ring frame 301 is slidably connected within the first working cavity 106 via a spline or keyway. A second ring frame 302 is slidably connected within the second working cavity 107. Both the first ring frame 301 and the second ring frame 302 have a fixing plate 204 connected inside. A connecting rod 303, which is L-shaped, is rotatably connected inside the locking bracket 105. One end of the connecting rod 303 has a first sliding groove, and a sliding pin located in the first sliding groove is installed on one side of the first ring frame 301. The other end of the connecting rod 303 has an arc-shaped portion 304, and second sliding grooves are provided on both sides of the arc-shaped portion 304. The function of the first and second sliding grooves is to accommodate changes in the position of the connecting rod 303 at the connection points with the parts on both sides. The outer wall of the second ring frame 302 is equipped with a sliding pin located in the second sliding groove. When the first ring frame 301 in the first working cavity 106 moves upward, it will drive the connecting rod 303 to rotate upward. At this time, the other end of the connecting rod 303 drives the second ring frame 302 to move towards the second positioning plate 202. At this time, the first positioning plate 201 and the second positioning plate 202 can simultaneously engage.

[0030] When tilt angle adjustment is not required, the fixed plate 204 and the first positioning plate 201 need to be connected together to improve overall stability. Only during adjustment is the contact between the fixed plate 204 and the first positioning plate 201 broken. This avoids continuous power control of the fixed plate 204, reducing power consumption. The following provides a structure that does not require power to drive the fixed plate 204 and the first positioning plate 201 into contact: Specifically, the first ring frame 301 and the first working cavity 106 are connected by a spring. Under the action of the spring, the fixed plate 204 contacts the first positioning plate 201 from below. A first electromagnet 305 is installed at the bottom of the first working cavity 106, and a ferromagnetic component that cooperates with the first electromagnet 305 is installed at the bottom of the first ring frame 301. When the first electromagnet 305 is energized, the magnetic field attracts the ferromagnetic component, which then drives the fixed plate 204 downwards via the first ring frame 301. At this time, the fixed plate 204 loses contact with the first positioning plate 201, and the spring at the bottom of the fixed plate 204 is compressed. An unlocking assembly for fixing the first ring frame 301 is provided on the side wall of the first working cavity 106. When the fixed plate 204 is at the bottom, the unlocking assembly fixes the fixed plate 204. When the unlocking assembly is activated, the fixed plate 204 returns to its original position under the action of the spring.

[0031] When the fixed plate 204 is at the bottom, it needs to be fixed to facilitate the tilt adjustment of the photovoltaic panel 110. After adjustment, the restriction on the fixed plate 204 is released, allowing it to return to its upward position. The following provides a structure for restricting the fixed plate 204: Specifically, a cavity is provided on the side wall of the first working chamber 106. The unlocking component includes a pin 306 slidably connected within the cavity, with the pin 306 facing the fixed plate 204. The pin 306 and the cavity are connected by a spring. One end of the pin 306 facing the first ring frame 301 has an upward-sloping surface. When the fixed plate 204 moves downward, the slope presses the pin 306 into the cavity, preventing it from affecting the downward movement of the fixed plate 204. A groove is provided on the side wall of the first ring frame 301 to cooperate with the pin 306. When the pin 306 is inserted into the groove, it can restrict the fixed plate 204. A second electromagnet 307 is installed inside the cavity, and one end of the pin 306 is connected to a ferromagnetic component that cooperates with the second electromagnet 307. When the fixed plate 204 moves downward, the pin 306 inserts into a groove on the outer wall of the fixed plate 204 to restrict the fixed plate 204, eliminating the need for the first electromagnet 305 to remain energized. When unlocking is required, the second electromagnet 307 is energized, at which point the pin 306 retracts into the cavity, losing its ability to restrict the fixed plate 204.

[0032] In one embodiment, when there are strong winds and the sun is moving, the equipment will be kept stationary to avoid reducing its stability; that is, the tilt angle will not be adjusted. The photovoltaic panel tilt angle will only be adjusted when the wind weakens to restore high power generation efficiency.

[0033] When encountering strong winds, multiple photovoltaic panels 110 located on the same plane have a large windward area and are subject to strong wind impact, making them susceptible to wind influence. This also leads to concentrated wind pressure and high driving force, affecting the stability of the drive structure. The following provides a structure that increases airflow channels and guides airflow: Specifically, a vertical plate 401 is internally connected to the photovoltaic support 102. The guiding component includes a guide rod 402 connected to the movable support 109. The guide rod 402 passes through the vertical plate 401. Under the action of the guide rod 402, the movable support 109 can extend outward, allowing the photovoltaic panels 110 on the same plane to be staggered, creating an airflow channel. The guide rod 402 and the vertical plate 401 are connected by a spring for easy resetting. The movable support 109 is externally connected to a drive structure, which pushes the photovoltaic panels 110 outward, allowing adjacent photovoltaic panels 110 to be staggered.

[0034] To improve power generation efficiency, photovoltaic panels 110 are arranged in multiple rows, both horizontally and vertically. Due to the multiple rows of photovoltaic panels 110, panels in the same row need to be pushed out to ensure consistent flow across the staggered channels and prevent misaligned airflow from affecting airflow. The following provides a structure for driving the entire row of photovoltaic panels 110: Specifically, the movable support 109 has flanges 403 on both sides, and a drive groove 404 is provided on one side of each flange 403. An L-shaped plate 405 is rotatably connected to the vertical plate 401, with the bent portion of the L-shaped plate 405 mounted on the vertical plate 401 via a rotating pin. One end of the L-shaped plate 405 is connected to a sliding pin located within the drive groove 404, and the other end is rotatably connected to a movable rod 406, which is connected to the entire row of L-shaped plates 405. An external drive structure is connected to the movable rod 406, and the drive device moves the movable rod 406 upwards. (Reference) Figure 2 When the movable rod 406 rotates upward, the L-shaped plate 405 rotates along the bend. The end of the L-shaped plate 405 located in the drive groove 404 pushes the folded edge 403 outward, thereby achieving the function of pushing multiple photovoltaic panels 110 outward.

[0035] The vertically arranged photovoltaic panels 110 need to be staggered. Therefore, it is necessary to set up several rows of photovoltaic panels 110 that remain stationary, so that there is a certain distance between the photovoltaic panels 110 that are in operation and those that are not. For example, odd-numbered rows need to be in operation, while even-numbered rows are not, so that the airflow channels between the odd and even rows can be staggered. The following is a structure for intermittently driving the photovoltaic panels 110 to operate: Specifically, a push-pull plate 407 is rotatably connected between two adjacent movable rods 406. The lifting assembly includes an electric telescopic rod 408 rotatably connected to a fixed bracket 108. The electric telescopic rod 408 has a power-off retention function, so that the photovoltaic panels 110 can be held after being extended. The output end of the electric telescopic rod 408 is rotatably connected to the push-pull plate 407. Since both ends of the electric telescopic rod 408 are rotatably connected, it can adapt to the positional changes of the push-pull plate 407 when it moves up and down. In one embodiment, a gap is provided between two adjacent movable supports 109 to allow airflow to pass through, thereby reducing airflow impact. When the movable supports 109 extend outward, the gap between the two photovoltaic panels 110 increases to increase the airflow rate. (Refer to the case under external wind flow.) Figure 6 , Figure 6 The black line segment with arrows indicates the direction of airflow.

[0036] Because the second ring frame 302 has an arc-shaped portion 304 on its exterior, it is inconvenient to use splines or keyways, which would affect the axial movement of the second ring frame 302. The following provides a structure for guiding the second ring frame 302: Specifically, the side of the second ring frame 302 away from the fixed plate 204 is connected to an optical axis that passes through the locking bracket 105, providing guidance. The second ring frame 302 and the second working cavity 107 are connected by a spring for easy resetting. When the first electromagnet 305 is energized, it can completely overcome the resistance of the spring at the bottom of the first ring frame 301 and the spring on the optical axis, thereby attracting the first ring frame 301 to the bottom. Since the photovoltaic panel 110 is usually installed on barren mountains or wasteland, making on-site equipment control inconvenient, the first electromagnet 305, the second electromagnet 307, and the electric telescopic rod 408 are connected to an external power supply device. The power supply device is connected to a communication module, allowing the user to remotely control the power supply device through the communication module, thereby achieving remote control and debugging of the equipment.

[0037] When in use, the horizontal drive component on the column 101 drives the adjustment frame 104 to adjust its orientation, and the vertical drive component on the adjustment frame 104 controls the horizontal bar 103 to adjust its horizontal angle so that the photovoltaic panel 110 can move with the sun and maximize the power generation efficiency of the photovoltaic panel 110.

[0038] When angle adjustment is required, the first electromagnet 305 is activated by remote control. The ferromagnetic component at the bottom of the fixed plate 204 moves downward under the action of magnetic force. At this time, the pin 306 is inserted into the groove on the outer wall of the fixed plate 204 to restrict the fixed plate 204. At this time, the tilt angle of the movable bracket 109 can be adjusted by the horizontal drive component and the vertical drive component, thereby maximizing the power generation efficiency.

[0039] When strong winds are detected or predicted, the remotely controlled second electromagnet 307 is activated. At this time, the pin 306 is pulled out of the groove on the outer wall of the fixed plate 204. The fixed plate 204 moves upward under the action of the bottom spring and contacts the upper first positioning plate 201. Simultaneously, the fixed plate 204, via the connecting rod 303, also contacts the second positioning plate 202 inside the second working chamber 107. At this point, the crossbar 103 is fixed to the column 101 via the locking bracket 105, improving wind resistance during strong winds.

[0040] Then, the electric telescopic rod 408 is activated, extending and causing the push-pull plate 407 to move upward. The push-pull plate 407, via the movable rod 406, causes the L-shaped plate 405 to rotate, thereby pushing out a row of folded edges 403. At this time, the photovoltaic panel 110 moves outward. External airflow can pass through the gap between the upper and lower photovoltaic panels 110, avoiding direct wind resistance and reducing overall wind resistance. The reduced wind impact force lowers the overturning moment and torque acting on the frame, pivot, drive mechanism, and column 101, preventing strong winds from overturning, bending the support, or damaging the photovoltaic panels.

[0041] The above embodiments are merely preferred embodiments of the present invention and should not be construed as limiting the scope of protection of the present invention. Any non-substantial changes and substitutions made by those skilled in the art based on the present invention shall fall within the scope of protection claimed by the present invention.
