A type of inclined-braced stable photovoltaic support structure

Abstract

This invention relates to the field of photovoltaic equipment technology, specifically a diagonal bracing stable photovoltaic support structure, including a base fixing plate, a diagonal bracing mechanism, a lifting mechanism, and a support positioning mechanism. The diagonal bracing mechanism is mounted on the base fixing plate and is used to adjust the tilt angle of the entire support. The lifting mechanism is located at the top of the diagonal bracing mechanism and is used to adjust the height of the support positioning mechanism. The top of the support positioning mechanism has a liftable pin for inserting into the photovoltaic panel mounting hole. Internally, it has a linkage system driven by the lifting mechanism. When the pin is axially inserted into the mounting hole and continues to rise, the linkage system converts part of the lifting force into a thrust that drives the side-mounted pin to move radially, causing the pin to engage in the positioning ring hole on the side wall of the mounting hole, achieving quick and reliable insertion and locking. This invention achieves integrated operation of installation positioning and locking through mechanical linkage, solving the problems of cumbersome adjustment and inconvenient installation and disassembly in the prior art, and improving the installation efficiency and structural stability of the photovoltaic support.

Description

Technical Field

[0001] This invention relates to the field of photovoltaic equipment technology, specifically a diagonally braced stable photovoltaic support structure. Background Technology

[0002] With the increasingly widespread application of photovoltaic technology, photovoltaic support structures, which support photovoltaic panels, are often combined with common outdoor supports such as awnings, pergolas, and carports. A typical photovoltaic support structure consists of columns, main joists, secondary joists, and photovoltaic panel installation. Furthermore, to enhance the structural stability between the columns and main joists, diagonal braces are usually connected between them to form a stable triangular structure.

[0003] The existing patent authorization number is CN208094487U, which discloses a photovoltaic bracket inclined brace clamp-type installation structure, including a column, a main keel, and an inclined brace extending at an angle and connecting the column and the main keel. The inclined brace has a column connector for connecting the column and a main keel connector for connecting the main keel at both ends. The column is cylindrical. The column connector includes an open-loop hoop for clamping the column and ear plates formed at both ends of the hoop. The two ear plates have aligned through holes, and an adjusting bolt is inserted through the through holes of both ear plates, with an adjusting nut threaded onto the adjusting bolt. Analysis of the above photovoltaic bracket structure reveals that it lacks effective adjustment capability during installation. Furthermore, positioning requires operating and rotating multiple cumbersome bolts. The interconnectivity between the various structures is insufficient, lacking effective coordination, resulting in insufficient linkage between positioning and disassembly, and overall inadequate flexibility. Its performance in terms of support stability and disassembly is mediocre.

[0004] In view of the above-mentioned problems, this application proposes a diagonal bracing type stable photovoltaic support structure. Summary of the Invention

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art will understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0035] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0036] Please see Figures 1-5A type of inclined bracing stable photovoltaic support structure includes a support positioning unit 2 that is inserted into the photovoltaic panel mounting hole 1. The top of the support positioning unit 2 is first axially inserted and then radially moved and limited, while the lower side is obliquely adjusted, so as to achieve efficient, accurate and fast installation and disassembly positioning with the photovoltaic panel mounting hole 1.

[0037] The support positioning unit 2 includes, from top to bottom, a support positioning mechanism 20, a lifting mechanism 30, a diagonal bracing mechanism 40, and a bottom fixing plate 50. The bottom fixing plate 50 is fixed to the ground or roof where the photovoltaic panel is installed. The diagonal bracing mechanism 40 is installed at the top center of the bottom fixing plate 50. The top of the diagonal bracing mechanism 40 is oscillatingly connected to the lifting mechanism 30, which is used to adjust the tilt angle of the lifting mechanism 30, so as to make corresponding tilt adjustments according to the installation angle requirements of the photovoltaic panel to be supported. The top of the lifting mechanism 30 is connected to the support positioning mechanism 20, which is used to adjust the height of the support positioning mechanism 20, so as to control its stable connection and support with the photovoltaic panel mounting hole 1 on the upper side. At the same time, a power transfer component is provided between the support positioning mechanism 20 and the lifting mechanism 30. The drive end of the power transfer component is connected to the power end of the lifting mechanism 30. When the lifting mechanism 30 is lifting, the power transfer component converts part of the lifting power of the lifting mechanism 30 into rotational kinetic energy, and then drives the top of the support positioning mechanism 20 to move radially and limit its position after being axially inserted into the photovoltaic panel mounting hole 1.

[0038] Specifically, the bottom fixing plate 50 has multiple mounting holes, which, together with tools such as anchor bolts, are used to fix the bottom fixing plate 50 to the corresponding ground or roof.

[0039] The diagonal bracing mechanism 40 includes a bottom connecting block 404 fixed to the top center of the bottom fixed plate 50. Two swing block frames 400 are symmetrically installed on both sides of the top of the bottom connecting block 404. A swing block 401 is connected between the tops of the two swing block frames 400 through a rotating rod. The top of the swing block 401 is connected to the bottom of the lifting mechanism 30. Under the action of the rotating rod, the swing block 401 is kept rotating. At the same time, threaded rods 402 are connected to both ends of the rotating rod. The threaded rods 402 move through the swing block frame 400 and the outer end is threaded with a locking nut 403. By rotating the locking nut 403, the contact force between the locking nut and the outer wall of the swing block frame 400 is adjusted, thereby limiting the swing of the rotating rod and adjusting the tilt angle of the swing block 401. Then, the overall swing angle of the lifting connecting plate 300 is controlled to realize the adjustable diagonal bracing.

[0040] The lifting mechanism 30 includes a bottom mounting plate 310 fixed to the top of two swing block frames 400. A lifting connecting plate 300 is provided directly above the bottom mounting plate 310. The bottom mounting plate 310 is adjusted in angle by the swing of the swing block 401. At the same time, a set of swing lifting components is provided between the lifting connecting plate 300 and the bottom mounting plate 310. The swing lifting components are controlled by manual rotation.

[0041] like Figure 7 As shown, the swing-type lifting assembly includes two pairs of U-shaped pins 301 fixed to both sides of the bottom of the base mounting plate 310. Each U-shaped pin 301 has an outwardly inclined upper swing rod 302 rotatably connected to its center via a swing shaft 313. Two shaft positioning rods 311 are installed on both sides of the top of the base mounting plate 310. A lower swing rod 303 is rotatably connected between each shaft positioning rod 311 via a swing shaft 313. Both ends of the upper swing rod 302 and the lower swing rod 303 have slots 304. Adjacent upper swing rods 302 and lower swing rods 303 are rotatably connected via a swing shaft 313, maintaining the upper swing rods 302 and lower swing rod 303 on both sides. The lower swing rods 303 can be longitudinally folded and raised. On the two swing shafts 313 located at the rotatable connection between the upper swing rod 302 and the lower swing rod 303, there are rod positioning blocks 305 and screw hole blocks 309 respectively. Rotating rods 307 and screws 308 are rotatably and threadedly connected in the rod positioning blocks 305 and the screw hole blocks 309 respectively. The rotating rods 307 and screws 308 are coaxially distributed and their adjacent ends are fixedly connected. By rotating the rotating rods 307, the screws 308 are driven to move horizontally in the screw hole blocks 309, thereby controlling the longitudinal folding and raising and lowering of the entire upper swing rods 302 and the lower swing rods 303, and then adjusting the height of the lifting connecting plate 300.

[0042] The top two sides of the lifting plate 300 are connected to the bottom of the support and positioning mechanism 20 through Z-shaped connecting rods 60. That is, when the lifting plate 300 is lifted, the height of the support and positioning mechanism 20 can be adjusted synchronously to allow it to be inserted into the photovoltaic panel mounting hole 1.

[0043] Preferably, the end of the rotating rod 307 away from the screw 308 is connected to an internal hexagonal cap 306, which is inserted into the internal hexagonal cap 306 by means of an internal hexagonal screw, thereby controlling the rotation of the rotating rod 307;

[0044] A stop gear 312 is installed in the middle of the two swing shafts 313 on the bottom mounting plate 310. The two stop gears 312 are meshed and connected, that is, the meshing rotation between the stop gears 312 increases the stability of the upper swing rod 302 and the lower swing rod 303 when folding and lifting.

[0045] Preferably, the screw 308, as a manual precision adjustment component, can be a trapezoidal threaded screw of M12×1.75 or M16×2. By rotating the internal hexagonal cap 306, the screw 308 pushes the screw hole block 309, causing the linkage mechanism to fold. In the design, the lifting height of the lifting connecting plate 300 can change by approximately 5mm to 15mm for each rotation of the rotating rod 307.

[0046] The diagonal bracing mechanism has a 40° angle adjustment range: by adjusting the angle of the swing block 401, the tilt angle of the entire bracket can be changed to adapt to different installation requirements. Its effective adjustment range can be set from 0° to 50°, covering the optimal installation tilt angle requirements of most photovoltaic panels.

[0047] like Figure 6 As shown, the support positioning mechanism 20 includes a rectangular support box 228 with a rectangular structure. The bottom two sides of the rectangular support box 228 are fixedly connected to the top of the Z-shaped connecting rod 60, that is, when the lifting connecting plate 300 is lifted, it directly controls the rectangular support box 228 to move.

[0048] The rectangular support box 228 has through holes on both sides of its top. A threaded cylinder 227 is connected to the bottom of each through hole. An adjusting screw 226 is threaded into the internal thread of the threaded cylinder 227. A lifting sleeve 225 is connected to the bottom of the adjusting screw 226. A sleeve rod 223 is fitted inside the bottom of the lifting sleeve 225. A driven spur gear 219 is connected to the bottom of the sleeve rod 223 via a connecting rod cylinder 222. A positioning key 224 is installed on the circumferential side wall of the sleeve rod 223. A slide rail is provided in the inner wall of the lifting sleeve 225 corresponding to the positioning key 224. The slide rail is slidably connected to the positioning key 224, thus keeping the lifting sleeve 225 fitted onto the sleeve rod 223. When the sleeve rod 223 rotates, it synchronously drives the lifting sleeve 225 to rotate, thereby controlling the lifting sleeve. The adjusting screw 226 at the top of 225 rotates along the inside of the inner threaded cylinder 227, thereby adjusting the height of the inner threaded cylinder 227. The top of the adjusting screw 226 is connected to the pin head 201 through the pin rod 202. A driving spur gear 220 meshes between the driven spur gears 219 on both sides. The bottom of the driving spur gear 220 is connected to the power transfer component. The tooth groove direction of the adjusting screws 226 on both sides is opposite to that of the inner threaded cylinder 227, ensuring that when the driving spur gear 220 drives the driven spur gears 219 on both sides to rotate, under the control of the connecting rod cylinder 222, the sleeve rod 223, and the lifting sleeve 225, the lifting direction of the adjusting screws 226 on both sides is consistent, thereby controlling the pin head 201 to rise and insert into the photovoltaic panel mounting hole 1 for pre-positioning.

[0049] Specifically, such as Figure 8As shown, the power transfer assembly includes a transfer link 229 connected to the bottom center of the drive spur gear 220. The lower side of the transfer link 229 moves through the rectangular support box 228 and the lifting plate 300 and is connected to a bevel gear II 316. A bevel gear I 315 is vertically meshed on one side of the bevel gear II 316. The middle part of the bevel gear I 315 is fixed on the rotating rod 307. That is, when the rotating rod 307 rotates, it drives the bevel gear I 315 to rotate synchronously, and then drives the bevel gear II 316 to rotate. In turn, under the connection of the transfer link 229, it drives the drive spur gear 220 to rotate, thus realizing the transfer of part of the lifting power to the drive spur gear 220.

[0050] Preferably, a positioning seat is rotatably mounted on the transfer link 229 located on the upper side of the bevel gear II 316. The positioning seat is fixed to the bottom mounting plate 310 on both sides by L-shaped fixing rods 314 to maintain the stable rotation of the transfer link 229.

[0051] In embodiments of the present invention, such as Figure 1 , Figure 2 , Figure 5 , Figure 9As shown, a piston cylinder 214 is positioned above the drive spur gear 220. A piston plate 216 is movable inside the piston cylinder 214. A piston rod 215 is connected to the top center of the piston plate 216. A connecting rod 211 is connected to the top of the piston rod 215 via a spring limiting ring 212. A side-positioning drive block 208 is mounted on the top of the connecting rod 211. Slide bars 209 are symmetrically mounted on both sides of the side-positioning drive block 208. A sliding groove 210 is formed in the wall of the rectangular support box 228 corresponding to the slide bar 209. A closed structure is provided at the bottom of the sliding groove 210. A return spring II 213 is fitted on the connecting rod 211 between the side-positioning drive block 208 and the spring limiting ring 212. When the return spring II 213 is in a free state, it keeps the side-positioning drive block 208 moving to the uppermost position, with the top of the side-positioning drive block 208 higher than the upper surface of the rectangular support box 228. Simultaneously, a main gas pipeline 21 is connected outward from one side of the bottom of the piston cylinder 214. 7. The main gas pipeline 217 is connected to auxiliary gas pipelines 221 on both sides. The auxiliary gas pipelines 221 are connected to an internal gas channel 218. The internal gas channel 218 is located at the center of the driven spur gear 219, connecting rod cylinder 222, sleeve rod 223, lifting sleeve 225, adjusting screw 226, and internal threaded cylinder 227. That is, when the piston plate 216 descends, it squeezes downward, forcing the gas in the bottom of the piston cylinder 214 into the main gas pipeline 217, auxiliary gas pipeline 221, and internal gas channel 218. At the same time, the downward force of the piston plate 216 comes from the side positioning drive block 208, that is, the pressure when the side positioning drive block 208 contacts the bottom of the photovoltaic panel on one side of the photovoltaic panel mounting hole 1. At this time, a certain part of the pin head 201 is inserted into the photovoltaic panel mounting hole 1. As the adjusting screw 226 continues to rise, it gradually controls the side positioning drive block 208 to contact the bottom of the photovoltaic panel and receive downward pressure.

[0052] Among them, the diameter of the piston cylinder 214 is the core of air pressure generation and transmission, and its diameter affects the driving force; preferably Φ40mm - Φ60mm.

[0053] The parameters of the return spring II 213 are used to support the side-positioning drive block 208 and reset it. Its initial preload must be able to overcome the weight of the side-positioning drive block 208 and the connecting rod 211, and can be set to 8-12N. The spring stiffness can be selected as 8-12 N / mm.

[0054] Diameter of main gas pipeline 217, auxiliary gas pipeline 221 and built-in gas transmission channel 218: To ensure the timeliness and effectiveness of gas pressure transmission, the inner diameter of the pipeline and channel should not be too small;

[0055] The preferred inner diameter of the main gas pipeline is Φ6mm, and the inner diameter of the auxiliary gas pipeline and the built-in gas transmission channel is Φ4mm.

[0056] Specifically, radially distributed channels connect to the top of the built-in gas transmission channel 218 on both sides. A side-mounted pin 206 is installed in a sealed, movable manner within the channel. An arc-shaped head 207 is connected to the outer end of the side-mounted pin 206, and the lower inner part is designed with an inclined surface structure. Simultaneously, an isosceles triangular guide plate 203 is installed at the top of the side-mounted positioning drive block 208. The gas transported upwards along the interior of the built-in gas transmission channel 218 is guided by the guide plate 203. A thrust is applied to the inclined surfaces of the two side-mounted pins 206, and then their outward radial movement is controlled. Simultaneously, a spring connecting plate 204 is installed on one side of the top of the side-mounted pins 206. A return spring I 205 is connected to the upper part of the channel sidewall of the spring connecting plate 204. When the return spring I 205 is in a free state, the arc-shaped head 207 is controlled to retract into the channel. At the same time, during the outward movement of the side-mounted pins 206, the pin rod 202 is also continuously rising. Therefore, a positioning ramp 11 is provided inside the photovoltaic panel mounting hole 1. The upper side of the positioning slope 11 is connected to radially distributed side positioning ring holes 10. As the pin 202 rises continuously, the side pin 206 also moves outward synchronously. Then the arc head 207 moves gradually along the positioning slope 11 until the arc head 207 moves into the side positioning ring hole 10. At this time, the pin 202 and the pin head 201 are positioned. When descending, the operation is reversed, that is, the side pin 206 gradually loses radial thrust, and then under the return force of the return spring I 205, the arc head 207 is controlled to move back gradually.

[0057] Preferably, in order to increase the limiting force between the arc-shaped head 207 and the positioning slope 11, multiple limiting patterns can be provided on the surface of the positioning slope 11.

[0058] In one embodiment of the present invention, the specific positioning of the gears, rotating rods, connecting rods and other structures in the above structure, as well as the required structural components, can all be achieved according to conventional structures, and will not be described in detail here.

[0059] It should be noted that the photovoltaic panel mounting hole 1 is an industry standard interface, and its diameter is usually Φ20mm-Φ30mm. This solution preferably uses Φ25mm as the design benchmark.

[0060] The diameter of pin 201 is slightly smaller than that of hole 1 in the photovoltaic panel mounting hole to ensure smooth insertion and fine-tuning. Preferably, it is Φ22mm, with a 1.5mm gap on one side between it and the Φ25mm mounting hole.

[0061] The radial travel of the side-mounted pin 206 determines the reliability of the locking. Based on the illustrated structure and conventional locking requirements, its effective extension length, i.e., the displacement of the arc-shaped head 207 from the retracted state to fully engaging with the side-mounted positioning ring hole 10, is set to 8mm-12mm; preferably 10mm.

[0062] The working principle of this invention is as follows: During idle periods in this device, all the aforementioned driving components (representing power elements, electrical devices, and compatible power supplies) are connected via wires. The electrical connections are completed in sequence between the working components. The detailed connection methods are well-known in the art. The following mainly describes the working principle and process, without further explanation of the electrical control.

[0063] Adjustment preparation stage: According to the installation tilt angle requirements of the photovoltaic panel, loosen the locking nut 403 of the inclined brace mechanism 40, manually adjust the angle of the swing block 401, thereby changing the tilt of the entire bracket, and then tighten the locking nut 403 again after adjustment.

[0064] During the initial adjustment and connection stage: Using a tool, rotate the hexagonal cap 306 of the lifting mechanism 30 to rotate the rotating rod 307 and the screw 308. The screw 308 pushes the screw hole block 309, causing the linkage group formed by the upper swing rod 302 and the lower swing rod 303 to fold or unfold, thereby driving the lifting connecting plate 300 to rise and fall. Then, through the Z-shaped connecting rod 60, the support positioning mechanism 20 is raised and lowered as a whole until the pin 201 at its top is aligned with and inserted into the photovoltaic mounting hole 1 of the photovoltaic panel.

[0065] Linkage locking phase:

[0066] a. While rotating the internal hexagonal cap 306 for lifting and lowering operations, the rotating rod 307 will drive the bevel gear I 315 on it to rotate.

[0067] b. The bevel gear I 315 drives the bevel gear II 316, which meshes with it, to rotate, and then drives the drive spur gear 220 to rotate through the transfer link 229.

[0068] c. The driving spur gear 220 drives the driven spur gears 219 on both sides to rotate synchronously in opposite directions. This is transmitted through the connecting rod cylinder 222, sleeve rod 223 and lifting sleeve 225, ultimately causing the adjusting screws 226 on both sides to rotate synchronously in the inner threaded cylinder 227 and extend upward, pushing the pin 202 and pin head 201 to continue moving upward.

[0069] d. After the pin head 201 is partially inserted into the mounting hole, the side-positioning drive block 208 at the top of the rising pin 202 will abut against the bottom surface of the photovoltaic panel and be subjected to downward pressure. This pressure is transmitted through the connecting rod 211 and the piston rod 215, pushing the piston plate 216 inside the piston cylinder 214 downward.

[0070] e. The piston plate 216 moves down to force the gas in the cylinder into the main gas pipeline 217 and the auxiliary gas pipeline 221, and then transports it upward through the built-in gas transmission channel 218.

[0071] f. After the upward airflow impacts the air guide plate 203, it applies a thrust to the inclined surfaces of the side-mounted pins 206 on both sides, overcoming the elastic force of the return spring I 205, and pushing the side-mounted pins 206 together with the arc-shaped head 207 at their ends to move outward radially.

[0072] g. As the pin 202 continues to rise, the arc-shaped head 207 slides along the positioning ramp 11 on the inner wall of the photovoltaic panel mounting hole 1 until it is completely inserted into the side positioning ring hole 10, thus completing the radial locking of the pin 202 and achieving a quick and stable connection between the photovoltaic panel and the bracket.

[0073] Disassembly process: Rotate the hexagonal cap 306 in the reverse direction, causing the adjusting screw 226 to drive the pin 202 to descend. The side-positioning drive block 208 loses pressure and resets under the action of the return spring II 213. The piston plate 216 rises under the action of air pressure difference, and the side-positioning pin 206 loses airflow thrust and retracts under the action of the return spring I 205, disengaging the arc-shaped head 207 from the side-positioning ring hole 10. The pin head 201 continues to descend and can then exit from the photovoltaic panel mounting hole 1.

Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
