Description

Technical Field

[0001] This invention relates to photovoltaic power generation technology, and in particular to a photovoltaic system suitable for undulating terrain. Background Technology

[0002] Photovoltaic power generation technology is being promoted and used more and more in response to the national call for energy conservation and emission reduction.

[0003] Photovoltaic power generation systems are often installed on flat ground to ensure that the photovoltaic panels are at the same height, which can avoid mutual shading and reduce wind force. The angle of the photovoltaic panels also needs to be uniform so that they can be adjusted synchronously with the direction of sunlight, thereby improving power generation efficiency. However, in the current technology, it is often difficult to install photovoltaic panel systems well and accurately in undulating areas or areas with an overall tilt angle. Summary of the Invention

[0004] Therefore, it is necessary to provide a photovoltaic system suitable for undulating terrain to address the above-mentioned problems.

[0005] This invention discloses a photovoltaic system suitable for undulating ground, installed on an uneven mounting surface. The photovoltaic system suitable for undulating ground includes: multiple support mechanisms disposed on the mounting surface; multiple photovoltaic panels, one-to-one installed on the support mechanisms; and a hydraulic control component connected to the support mechanisms via pipes, which controls the height of the support mechanisms by controlling the hydraulic pressure within the support mechanisms, thereby enabling the multiple photovoltaic panels to maintain the same height.

[0006] In one embodiment, the hydraulic control assembly includes a housing, a piston plate, an elastic element, a counterweight plate, and an electric rod. A first piston chamber is formed between the housing and the piston plate. The first piston chamber is connected to multiple support mechanisms via pipelines. The upper end of the electric rod is fixed to the top of the housing, and the lower end is fixedly connected to the counterweight plate. The counterweight plate is located above the piston plate. The upper end of the elastic element is fixed to the counterweight plate, and the lower end is fixed to the piston plate.

[0007] In one embodiment, the support mechanism includes a tripod, a balance ball, an outer shell rod, and a central column. The tripod has a spherical groove, the balance ball is rotatably connected to the spherical groove and can rotate freely, the outer shell rod passes through the balance ball and can be engaged with a snap-fit ​​device on the balance ball, the outer shell rod can rotate to a vertical position in its natural state, the central column is slidably disposed within the outer shell rod, and a piston portion is provided at the lower end of the central column. A second piston chamber is formed between the piston portion and the outer shell rod, the second piston chamber is connected to the first piston chamber through a pipe, and the liquid levels in the second piston chambers of the multiple support mechanisms can be at the same horizontal level, thereby keeping the photovoltaic panel at the same horizontal height.

[0008] In one embodiment, the outer casing rod includes a hemispherical counterweight at the bottom, the counterweight having a plurality of connection ports communicating with the second piston chamber, and the pipe communicating with the second piston chamber through the connection ports.

[0009] In one embodiment, the bottom of the counterweight is provided with a plug-in cone that can be inserted into the mounting surface to achieve a fixing effect.

[0010] In one embodiment, the outer side of the outer casing rod is provided with locking teeth, and the balance ball is provided with locking members. The locking members are rotatably disposed on the balance ball, and the locking members can be locked into the locking teeth, thereby restricting the sliding of the outer casing rod along the balance ball.

[0011] In one embodiment, a guide telescopic rod is provided in the second piston chamber. The upper end of the guide telescopic rod is connected to the piston part, and the lower end is connected to the counterweight part. A spring is sleeved on the outside of the guide telescopic rod. The lower end of the spring abuts against the counterweight part, and there is a gap between the upper end of the spring and the piston part.

[0012] In one embodiment, the counterweight has a cavity inside, which is connected to the second piston cavity and to the first piston cavity through the pipe.

[0013] In one embodiment, the counterweight is provided with a uniformly spaced mounting groove in a ring shape, and a counterweight can be placed in the mounting groove, so that the outer shell rod is in an inclined state in its natural state.

[0014] In one embodiment, the photovoltaic system suitable for undulating ground includes four support structures and four photovoltaic panels arranged in a rectangular array.

[0015] The advantages of this invention are:

[0016] (1) By setting up a support mechanism, the outer shell rod can be kept vertical by gravity, so that the photovoltaic panels can maintain a uniform orientation. With the help of the hydraulic control components, the central column can be at the same horizontal level, so that multiple photovoltaic panels can have the same height and angle, which makes it easy to adjust and control.

[0017] (2) By connecting the first piston chamber and the second piston chamber, the photovoltaic panel can automatically undulate and buffer the wind force when it is subjected to wind force, thereby preventing the support mechanism from being blown down by excessive wind force.

[0018] (3) By setting up elastic elements and counterweight plates, the liquid is pressed into the support mechanism by the weight of the counterweight plates, which can make the central column rise. On rainy days and at night, the counterweight plates are raised by retracting the electric rod, which can make the liquid flow back into the first piston chamber, thereby reducing the height of the photovoltaic panel and improving its stability.

[0029] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

When a component is said to be "set" to another component, it can be directly set to the other component or it may also be in the middle of another component. When a component is said to be "fixed" to another component, it can be directly fixed to the other component or it may also be in the middle of another component.

[0031] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein in the specification of this invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "or / and" as used herein includes any and all combinations of one or more of the associated listed items.

[0032] like Figures 1 to 9 As shown, the present invention discloses a photovoltaic system suitable for undulating ground, installed on a non-flat mounting surface 01. The photovoltaic system suitable for undulating ground includes: multiple support mechanisms 1, disposed on the mounting surface 01; multiple photovoltaic panels 2, installed one-to-one on the support mechanisms 1; and a hydraulic control component 3, connected to the support mechanisms 1 through pipes, which controls the height of the support mechanisms 1 by controlling the hydraulic pressure within the support mechanisms 1, thereby enabling the multiple photovoltaic panels 2 to maintain the same height.

[0033] It should be noted that the present invention is suitable for installation on ground with certain undulations and gentle slopes that cannot be accurately measured. By adjusting the support mechanism 1 during installation, the photovoltaic panel 2 can be placed on the same horizontal plane and maintain the same installation angle, thereby laying a structural foundation for the photovoltaic panel 2 to change its orientation according to the angle of the sun.

[0034] Preferred, such as Figures 7 to 9As shown, the hydraulic control assembly 3 includes a housing 31, a piston plate 32, an elastic element 33, a counterweight plate 34, and an electric rod 35. A first piston chamber 311 is formed between the housing 31 and the piston plate 32. The first piston chamber 311 is connected to multiple support mechanisms 1 through pipelines. The upper end of the electric rod 35 is fixed to the top of the housing 31, and the lower end is fixedly connected to the counterweight plate 34. The counterweight plate 34 is located above the piston plate 32. The upper end of the elastic element 33 is fixed to the counterweight plate 34, and the lower end is fixed to the piston plate 32.

[0035] Understandably, the hydraulic control component 3 synchronously controls the height of multiple support mechanisms 1 through a liquid medium. By extending the electric rod 35, the liquid in the first piston chamber 311 can be forced into the support mechanism 1, thereby raising the support mechanism 1 and then raising the photovoltaic panel 2.

[0036] Preferred, such as Figures 2 to 6 As shown, the support mechanism 1 includes a tripod 11, a balance ball 12, an outer shell rod 13, and a central column 15. The tripod 11 is provided with a spherical groove 111. The balance ball 12 is rotatably connected to the spherical groove 111 and can rotate freely. The outer shell rod 13 passes through the balance ball 12 and can be engaged with the snap-fit ​​part 121 on the balance ball 12. The outer shell rod 13 can rotate to a vertical position in its natural state. The central column 15 is slidably disposed in the outer shell rod 13, and a piston part 151 is provided at the lower end of the central column 15. A second piston chamber 131 is formed between the piston part 151 and the outer shell rod 13. The second piston chamber 131 is connected to the first piston chamber 311 through a pipe. The liquid levels of the second piston chambers 131 of the multiple support mechanisms 1 can be at the same horizontal level, thereby making the photovoltaic panel 2 at the same horizontal height.

[0037] Understandably, when the support mechanism 1 needs to be installed, the tripod 11 is placed on the mounting surface 01, and then the balance ball 12 is rotated freely by the weight of the outer shell rod 13. At this time, the outer shell rod 13 is in a vertical state. Then, the locking piece 121 is released, allowing the outer shell rod 13 to fall freely and be fixed on the mounting surface 01. Then, the locking piece 121 is locked to fix the outer shell rod 13, so that the outer shell rod 13 can remain in a vertical state.

[0038] Preferably, the outer casing rod 13 includes a hemispherical counterweight 132 disposed at the bottom, and the counterweight 132 is provided with a plurality of connection ports 141 communicating with the second piston chamber 131, and the pipe is connected to the second piston chamber 131 through the connection ports 141.

[0039] It should be noted that when the mounting surface 01 is a soft structure, such as a sand and gravel layer, the hemispherical counterweight 132 can be partially submerged in it, thereby improving the stability of the support mechanism 1.

[0040] Preferably, the bottom of the counterweight 132 is provided with a plug cone 142, which can be inserted into the mounting surface 01 to play a fixing role.

[0041] Understandably, by setting the insertion cone 142, the stability of the outer casing rod 13 can be further improved.

[0042] Preferably, the outer side of the outer shell rod 13 is provided with a locking tooth 133, and the balance ball 12 is provided with a locking member 121. The locking member 121 is rotatably disposed on the balance ball 12, and the locking member 121 can be locked in the locking tooth 133, thereby restricting the sliding of the outer shell rod 13 along the balance ball 12.

[0043] Preferably, a guide telescopic rod 134 is provided in the second piston chamber 131. The upper end of the guide telescopic rod 134 is connected to the piston part 151, and the lower end is connected to the counterweight part 132. A spring 135 is sleeved on the outside of the guide telescopic rod 134. The lower end of the spring 135 abuts against the counterweight part 132, and there is a gap between the upper end and the piston part 151.

[0044] It should be noted that when the photovoltaic panel 2 descends, it can abut against the spring 135 for cushioning, preventing the photovoltaic panel 2 from breaking due to excessive descent. However, when the photovoltaic panel is in operation, the spring 135 does not abut against the lower end of the piston part 151, so that the piston part 151 is only adjusted in position by the pressure of the liquid. It is worth mentioning that the guide telescopic rod 134 reduces the cross-sectional area of ​​the second piston chamber 131, thereby enabling more accurate adjustment of the height of the central column 15.

[0045] Preferably, the counterweight 132 has a cavity 143 inside, which is connected to the second piston cavity 131 and to the first piston cavity 311 through the pipe.

[0046] It is worth mentioning that the cavity 143 contains liquid for a long time, which can serve as a counterweight.

[0047] Preferably, the counterweight part 132 is provided with a uniformly spaced mounting groove 144 in a ring shape, and a counterweight can be placed in the mounting groove 144 so that the outer shell rod 13 is in an inclined state in its natural state.

[0048] It is understandable that by setting a counterweight, the outer casing rod 13 can have a certain uniform tilt angle.

[0049] In this embodiment, the photovoltaic system suitable for undulating ground includes four support structures 1 and four photovoltaic panels 2, which are arranged in a rectangular array.

[0050] The working principle of this invention is as follows:

[0051] S1: Install the support mechanism 1, arrange the support mechanism 1 in a matrix on the mounting surface 01, so that the outer shell rod 13 hangs down naturally and moves to a vertical state under the action of the counterweight 132. Rotate the locking piece 121 to disengage the locking piece 121 from the locking tooth 133, so that the outer shell rod 13 falls down naturally, so that the insertion cone 142 extends into the mounting surface 01. Then rotate the locking piece 121 to fix the outer shell rod 13, and complete the installation of the support mechanism 1. At this time, the outer shell rod 13 is in a vertical state.

[0052] S2: Inject liquid and control the extension of the electric rod 35, so that the liquid in the first piston chamber 311 is squeezed and enters the second piston chamber 131 of each support mechanism 1 through the pipe, thereby raising the central column 15. Since the liquid in each second piston chamber 131 is interconnected, the liquid in each second piston chamber 131 has the same liquid level, thereby keeping each central column 15 at the same horizontal height.

[0053] S3: Install photovoltaic panel 2, and install photovoltaic panel 2 on the top of the central column 15.

[0054] In addition, it should be noted that after installation, the height of the central column 15 decreases, causing some of the liquid in the second piston chamber 131 to flow back into the first piston chamber 311. At this time, the piston part 151 and the upper end of the spring 135 still maintain a certain gap.

[0055] When the wind is strong, the photovoltaic panel 2 can rise or fall under the influence of the wind to provide cushioning, thereby reducing the damage of strong winds to the photovoltaic system. The flow of liquid can reset the photovoltaic panel 2 after it has risen or fallen, so that all the photovoltaic panels 2 in the photovoltaic system are at the same horizontal height, avoiding mutual shading due to height differences, and facilitating the adjustment of the direction and angle of the photovoltaic system.

[0056] When power generation is not possible at night, or when strong winds may damage the photovoltaic system, shortening the pole 35 can draw the liquid in the second piston chamber 131 into the first piston chamber 311, thereby reducing the height of the support mechanism 1, lowering the center of gravity, and thus improving the wind resistance of the photovoltaic system.

[0057] It is worth mentioning that by adjusting the weight of the counterweight 34, the liquid level difference between the second piston chamber 131 and the first piston chamber 311 can be adjusted. Thus, in other embodiments, each hydraulic control component 3 controls a row of support mechanisms, and multiple rows of support mechanisms are set up, so that the weight of the counterweight plate 34 in the hydraulic control component changes in a gradient, thereby forming a photovoltaic system with multiple gradient levels. This is more suitable for the needs of high-latitude regions. In other embodiments, the arrangement can also be set with a high center and low periphery, or a high center and low sides, which can be adjusted according to actual needs to suit different environments.

[0058] In addition, in this embodiment, the photovoltaic panel 2 is fixed after being connected to the central column. However, in other embodiments, an angle adjustment mechanism can be provided at the top of the central column so that the angle of the photovoltaic panel can be adjusted. Angle adjustment is a conventional design in the photovoltaic field and will not be described in detail here.

[0059] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0060] The embodiments described above are merely illustrative of several implementations of the present invention, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the invention patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these all fall within the protection scope of the present invention. Therefore, the protection scope of this invention patent should be determined by the appended claims.
