Description

Technical Field

[0001] This invention relates to the field of photovoltaic support technology, and in particular to a quick leveling and fixing device for photovoltaic supports. Background Technology

[0002] Flexible photovoltaic (PV) mounting systems offer advantages such as ease of installation and operation. However, in large-scale PV panel installation areas, the long length of the flexible modules and the influence of gravity cause them to bend, resulting in downward sag rather than a straight line. Consequently, the surfaces of each PV module are not parallel to each other, and each module is not at its optimal tilt angle due to the curvature of the flexible modules. This is especially problematic in the morning or afternoon when the sun is at its strongest, leading to varying power outputs within the same string of PV modules and affecting the overall power plant efficiency. Therefore, regular leveling of the PV modules is necessary. Summary of the Invention

[0003] The main objective of this invention is to provide a quick leveling and fixing device for photovoltaic brackets, which aims to solve existing technical problems.

[0004] To achieve the above objectives, the present invention provides a rapid leveling and fixing device for photovoltaic (PV) brackets, applied to flexible PV brackets. The flexible PV bracket includes steel cables, and the rapid leveling and fixing device includes…

[0005] The guide rail is fixed at both ends;

[0006] The leveling assembly includes a jacking cable mechanism for lifting the steel cable, a supporting cable mechanism for supporting the steel cable in sections, and a pulling cable mechanism for fixing the ends of the steel cable. The jacking cable mechanism, the supporting cable mechanism, and the pulling cable mechanism are all mounted on the guide rail. The jacking cable mechanism and the supporting cable mechanism are movably mounted, the pulling cable mechanism is fixedly mounted, and the supporting cable mechanism is located between the jacking cable mechanism and the pulling cable mechanism. The supporting cable mechanism includes at least two support cable structures, which are arranged sequentially on the guide rail after the jacking cable mechanism.

[0007] Furthermore, the jacking mechanism includes a first housing, a first lifting unit is provided on the top of the first housing, and a first jacking block is provided on the top of the first lifting unit;

[0008] The first housing is detachably connected to the first slider, and the first slider is movably connected to the guide rail.

[0009] Furthermore, the cable support mechanism includes a second housing, a second lifting unit is provided on the top of the second housing, and a top cable disc is provided on the top of the second lifting unit. The top cable disc is rotatable around its own axis.

[0010] The second housing is detachably connected to the second slider, and the second slider is movably connected to the guide rail.

[0011] Furthermore, the second housing has an opening communicating with the interior on the side facing the top cable mechanism. The upper and lower ends of the opening extend to the upper and lower surfaces of the second housing. The top surface of the second housing is provided with a limiting groove adapted to the cable support structure. The cable support structure is separated from and retracted from the second housing by an arrangement mechanism provided at the top of the opening. The bottom of the second housing is provided with an auxiliary wheel that contacts the guide rail.

[0012] Furthermore, the cable support structure includes a support column, an auxiliary support unit at the top of the support column, a slot on the support column, a second top wire block at the top of the auxiliary support unit, an insertion post at the bottom of the support column, and an insertion hole adapted to the insertion post on the guide rail. A limiting plate adapted to the limiting groove is fitted on the support column.

[0013] Furthermore, both ends of the first top wire block and the second top wire block are slidably connected to floating blocks. Rotatable clamping blocks are provided on both sides of the floating blocks. Gears are provided at the ends of the clamping blocks. Tooth grooves that mesh with the gears are provided on the floating blocks. The movement of the floating blocks causes the clamping blocks on both sides to move closer or further away.

[0014] Furthermore, the cable mechanism includes a third housing, which is detachably connected to a third slider. The third slider is fixedly connected to the guide rail. A third lifting unit is provided on the top surface of the third housing. A rectangular frame is provided at the top of the third lifting unit. A sliding movable block is provided inside the rectangular frame. The movable block is controlled to move by a linear unit. A lasso block is provided on the movable block. The lasso block is composed of two hinged arc-shaped blocks and bolts.

[0015] Furthermore, the arrangement mechanism includes two linear modules distributed on both sides of the top of the opening, a crossbeam between the two linear modules, a lifting mechanism on the crossbeam, and a fork at the end of the lifting mechanism.

[0017] Furthermore, both ends of the shift fork are provided with shift levers, and the shift levers are provided with protrusions.

[0018] The beneficial effects of this invention are reflected in:

[0019] This invention uses a top cable mechanism to provide fixed-point support and leveling for the lowest point of the steel cable, and a support cable mechanism to level the steel cable in sections from the middle to the end to distribute the pressure. Then, the end of the steel cable is fixed throughout the process by a cable tensioning mechanism. After leveling, the length of the leveled end of the steel cable is tightened, which makes it convenient for operators to re-fix the steel cable. This invention achieves rapid leveling of the photovoltaic support, reduces manual labor intensity, and improves efficiency.

[0020] This invention releases multiple independent and separate cable structures in sequence, with the steel cable transitioning from the middle section to the end section for support. This not only avoids the problem of reduced leveling accuracy caused by large-span support, but also provides stable support for photovoltaic modules.

[0021] This invention sets up the top cable mechanism, the support cable mechanism, and the pull cable mechanism independently, so that they can move to the designated position according to their respective functions during operation, and can also be combined after leveling, which facilitates the overall transportation and subsequent leveling operations.

[0039] 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 a part of the embodiments of the present invention, and not all of them. Unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other. 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.

[0040] Please see Figure 1-10 This invention provides a quick leveling and fixing device for photovoltaic brackets, which is applied to flexible photovoltaic brackets. The flexible photovoltaic brackets include steel cables. Specifically, the quick leveling and fixing device for photovoltaic brackets includes a guide rail 100, which is fixed at both ends. Specifically, the two ends of the guide rail 100 are fixed to the support system of the flexible photovoltaic bracket.

[0041] The leveling assembly 200 includes a jacking cable mechanism 210 for jacking up the steel cable, a support cable mechanism 220 for supporting the steel cable in sections, and a tension cable mechanism 230 for fixing the ends of the steel cable. The jacking cable mechanism 210, the support cable mechanism 220, and the tension cable mechanism 230 are all mounted on the guide rail 100. The jacking cable mechanism 210 and the support cable mechanism 220 are movable, while the tension cable mechanism 230 is fixed. The support cable mechanism 220 is located between the jacking cable mechanism 210 and the tension cable mechanism 230, and the support cable mechanism 220 includes at least two cable support structures 221, which are arranged sequentially on the guide rail 100 after the jacking cable mechanism 210.

[0042] In this embodiment, during use, the jacking cable mechanism 210 is moved below the lowest point of the steel cable, and the cable pulling mechanism 230 is positioned and fixed at the end of the steel cable. Then, the jacking cable mechanism 210 is controlled to push the steel cable to a specified height (the specified height refers to the height of the steel cable after initial installation and leveling). Then, the cable supporting mechanism 220 is used to level the steel cable from the middle section to the end section to distribute the pressure. The end of the steel cable is then fixed throughout the process by the cable pulling mechanism 230. After leveling, the length of the leveled end of the steel cable is tightened, which makes it convenient for operators to re-fix the steel cable. This achieves rapid leveling of the photovoltaic support, reduces manual labor intensity, and improves efficiency.

[0043] In this embodiment, the jacking mechanism 210 includes a first housing 211, and a first lifting unit 212 is provided on the top of the first housing 211. Specifically, the first lifting unit 212 may be a hydraulic rod. A first jacking block 213 is provided on the top of the first lifting unit 212. Specifically, the first jacking block 213 has an arc-shaped groove.

[0044] The first housing 211 is detachably connected to the first slider 101; specifically, the bottom of the first housing 211 is provided with a plug-in post, and the first slider 101 is provided with a cylindrical column; the first slider 101 is movably connected to the guide rail 100. Specifically, the first slider 101 is provided with a roller, which is driven by a motor, and the side of the guide rail 100 is provided with a wheel groove, so the first slider 101 can be controlled to move along the guide rail 100.

[0045] In this embodiment, the first slider 101 can move the first housing 211 to below the sag point of the steel cable. In conjunction with the first lifting unit 212, the first top line block 213 contacts the steel cable and pushes it to be leveled to the specified height, thereby achieving the leveling operation of the lowest sag point of the steel cable.

[0046] In this embodiment, the cable support mechanism 220 includes a second housing 222, and a second lifting unit 223 is provided on the top of the second housing 222. Specifically, the second lifting unit 223 may be a hydraulic rod. A top cable plate 224 is provided on the top of the second lifting unit 223. The top cable plate 224 is rotatable around its own axis. Specifically, the top cable plate 224 has an annular groove for holding the steel cable.

[0047] The second housing 222 is detachably connected to the second slider 102. Specifically, the bottom of the first housing 211 is provided with a plug-in post, and the second slider 102 is provided with a cylindrical post. The second slider 102 is movably connected to the guide rail 100. Specifically, the second slider 102 is provided with a roller, which is driven by a motor. The side of the guide rail 100 is provided with a wheel groove, and the second slider 102 can be controlled to move along the guide rail 100.

[0048] In this embodiment, after the jacking mechanism 210 moves below the drooping point of the steel cable and levels and supports the steel cable, the second lifting unit 223 makes the jacking plate 224 contact the steel cable and maintain the same leveling height as the first jacking block 213. Then, in conjunction with the second slider 102, the second housing 222 moves along the guide rail 100, so that the jacking plate 224 moves from the drooping point of the steel cable to the end, so that after the steel cable is leveled, it maintains the leveling height and gradually transitions to the end for leveling.

[0049] Specifically, after the second lifting unit 223 drives the top cable disk 224 to contact the steel cable, depending on whether the steel cable has a connection point with the photovoltaic module, if there is no connection point, the top cable disk 224 will always maintain contact with the steel cable as the second slider 102 moves. If there is a connection point, the second lifting unit 223 will control the disengagement from the steel cable at the connection point, and the cable will re-contact after passing the connection point. Since the support cable structure 221 is arranged sequentially, and in conjunction with the cable pulling mechanism 230, the problem of the steel cable resetting to its downward point after the top cable disk 224 disengages from the steel cable can be avoided.

[0050] In this embodiment, the second housing 222 has an opening 222a communicating with the interior on the side facing the top cable mechanism 210. The upper and lower ends of the opening 222a extend to the upper and lower surfaces of the second housing 222. The top surface of the second housing 222 is provided with a limiting groove 222b adapted to the support cable structure 221. The support cable structure 221 is separated from and retracted from the second housing 222 by an arrangement mechanism 225 provided at the top of the opening 222a.

[0051] The bottom of the second housing 222 is provided with an auxiliary wheel 226 that contacts the guide rail 100. Since the support structure 221 is separated and retracted from one end of the second housing 222, in order to avoid the movement of the support structure 221, the bottom end of the second housing 222 is connected to the second slider 102 near the end position. The auxiliary wheel 226 can provide stable support for the second housing 222 and ensure the stability of movement.

[0052] In this embodiment, after the top cable mechanism 210 levels the drooping position of the steel cable, as the second slider 102 drives the second housing 222 to move along the guide rail 100 from the drooping point of the steel cable to the end, the arrangement mechanism 225 sequentially removes the support structure 221 from the second housing 222 and places it in sections on the guide rail 100. This provides transitional support and leveling for the steel cable from the middle section to the end, which avoids the problem of decreased leveling accuracy caused by large-span support and provides stable support for the photovoltaic module.

[0053] In this embodiment, the cable structure 221 includes a support column 2211, an auxiliary support unit 2212 is provided at the top of the support column 2211, and a slot is provided on the support column 2211. Specifically, the auxiliary support unit 2212 can be a hydraulic rod. The top of the auxiliary support unit 2212 is provided with a second top wire block 2213. Specifically, the second top wire block 2213 has an arc-shaped groove.

[0054] The bottom end of the support column 2211 is provided with a plug 2214, and the guide rail 100 is provided with a plug hole 103 adapted to the plug 2214. The support column 2211 is fitted with a limiting plate 2215 adapted to the limiting groove 222b.

[0055] In this embodiment, as the second slider 102 drives the second housing 222 to move along the guide rail 100, the arrangement mechanism 225 sequentially takes out the support cable structure 221 and places it on the guide rail 100. Specifically, the arrangement mechanism 225 contacts the slot on the support column 2211, lifts it upward to make the limiting plate 2215 disengage from the limiting groove 222b, and then moves laterally to the opening 222a. Finally, the insertion column 2214 moves downward to connect with the insertion hole 103 on the guide rail 100. Subsequently, the auxiliary support unit 2212 drives the second top wire block 2213 to contact the steel cable, thereby releasing the support cable structure 221. This achieves the transition support and leveling of the steel cable from the middle section to the end, which can avoid the problem of reduced leveling accuracy caused by large-span support and provide stable support for photovoltaic modules.

[0056] In this embodiment, both ends of the first top wire block 213 and the second top wire block 2213 are slidably connected to floating blocks 300, and rotatable clamping blocks 301 are provided on both sides of the floating blocks 300; specifically, the clamping blocks 301 are rotatably connected to the first top wire block 213 and the second top wire block 2213 respectively through rotating shafts.

[0057] The end of the clamping block 301 is provided with a gear 302, and the floating block 300 is provided with a tooth groove that meshes with the gear 302. The movement of the floating block 300 causes the clamping blocks 301 on both sides to move closer or further away.

[0058] In this embodiment, when the first top wire block 213 and the second top wire block 2213 are pushed to contact the steel cable, the floating block 300 contacts the steel cable, causing the floating block 300 to move downward and synchronously drive the gear 302 to rotate, so that the two clamping blocks 301 move towards each other and tightly clamp the steel cable. This can reduce the risk of easy movement after the support cable structure 221 is separated from the second housing 222, and thus avoid the problem of low leveling accuracy.

[0059] In this embodiment, the cable mechanism 230 includes a third housing 231, which is detachably connected to the third slider 104, and the third slider 104 is fixedly connected to the guide rail 100. Specifically, the bottom of the third housing 231 is provided with a plug-in post, and the third slider 104 is provided with a column.

[0060] The top surface of the third housing 231 is provided with a third lifting unit 232, the top of the third lifting unit 232 is provided with a rectangular frame 233, and a sliding movable block 234 is provided inside the rectangular frame 233. The movable block 234 is controlled to move by a linear unit 235. Specifically, the linear unit 235 can be an electric push rod or a cylinder rod.

[0061] The movable block 234 is provided with a lasso block 236, which consists of two hinged arc-shaped blocks and bolts.

[0062] In this embodiment, when using this device, the third housing 231 is first connected to the third slider 104, and then the lasso block 236 is put on the steel cable and fixedly connected. Since the third slider 104 is fixedly connected to the guide rail 100, it is ensured that the end of the steel cable will not move during the leveling process. After the leveling support from the drooping point of the steel cable to the end is achieved by the top cable mechanism 210 and the support cable mechanism 220, the excess steel cable segment that has been leveled will droop at the end. At this time, the linear unit 235 controls the movable block 234 to move towards the end of the steel cable, so that the contact section between the steel cable and the photovoltaic module is horizontally taut. With the help of the staff, the end of the steel cable is unlocked and fixed again to complete the entire leveling and fixing operation.

[0063] In this embodiment, the arrangement mechanism 225 includes two linear modules 2251 distributed on both sides of the top of the opening 222a. A crossbeam 2252 is provided between the two linear modules 2251. A lifting mechanism 2253 is provided on the crossbeam 2252, and a fork 2254 is provided at the end of the lifting mechanism 2253. Specifically, the lifting mechanism 2253 can be a hydraulic telescopic rod.

[0064] In this embodiment, when the support cable structure 221 is released onto the guide rail 100, the linear module 2251 first drives the shift fork 2254 to approach the support cable structure 221 and contact the slot on the support column 2211. Then, the lifting mechanism 2253 drives the support cable structure 221 to move upward as a whole, so that the limiting plate 2215 disengages from the limiting groove 222b and moves laterally to the opening 222a. Finally, the insertion column 2214 moves downward and connects with the insertion hole 103 on the guide rail 100, thus completing the separation and release of the support cable structure 221.

[0065] In this embodiment, the first housing 211 and the third housing 231 are provided with connecting grooves 200a at their ends, and the second housing 222 is provided with connecting posts 200b at both ends that are adapted to the connecting grooves. After the connecting posts 200b are connected to the connecting grooves 200a, they are fixed by fastening bolts 200c. The bottom of the first housing 211, the second housing 222 and the third housing 231 are provided with support legs 200d.

[0066] In this embodiment, before use, the first housing 211, the second housing 222, and the third housing 231 are connected together to facilitate movement and handling. During use, the fastening bolts are removed, and the plugs on the first housing 211, the second housing 222, and the third housing 231 are inserted into the cylinders on the first slider 101, the second slider 102, and the third slider 104 respectively. Then, in conjunction with the movement of the first slider 101 and the second slider 102, the top cable mechanism 210 and the support cable mechanism 220 are moved and leveled.

[0067] In this embodiment, both ends of the shift fork 2254 are provided with shift levers, and the shift levers are provided with protrusions. Specifically, the slot on the support column 2211 is provided with a groove that matches the protrusion.

[0068] In this embodiment, the release and retraction of the cable support structure 221 can be achieved without adjusting the direction of the second housing 222 through the levers at both ends, making the operation simple and quick; the cooperation of the protrusions and grooves can improve the stability during the separation and retraction of the cable support structure 221 through the arrangement mechanism 225.

[0069] It should be noted that if the embodiments of the present invention involve directional indicators such as (up, down, left, right, front, back, etc.), the directional indicators are only used to explain the relative positional relationship and movement of the components in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicators will also change accordingly.
