Description

Technical Field

[0001] The present invention relates to the technical field of photovoltaic power generation, and in particular to a photovoltaic mounting bracket for use in steep slope areas. Background Art

[0002] As solar power generation technology matures, photovoltaic power generation is increasingly being used, fully utilizing solar energy. Due to the limited availability of flat, open terrain and the relatively abundant land resources in mountainous areas, deploying photovoltaic modules in mountainous areas has become a trend in photovoltaic power generation construction.

[0003] PV panels are mounted on sloped ground using brackets, with the panel tilted in a direction roughly aligned with the slope. For a single-column PV bracket, the lower end is fixed to the foundation, while the upper end supports the approximate center of the PV panel. Auxiliary brackets are used to enhance the panel's stability or adjust its tilt.

[0004] However, when this type of bracket encounters extreme weather such as strong winds, the photovoltaic modules on it are prone to swaying in the wind, and the stability is relatively poor, which can easily cause damage to the photovoltaic modules. Summary of the Invention

[0005] Based on this, the present invention provides a photovoltaic mounting bracket for steep slope areas to solve the technical problem that the photovoltaic components on the existing brackets are easily shaken by the wind when encountering extreme weather such as strong winds, and the stability is relatively poor, which can easily cause damage to the photovoltaic components.

[0006] The present invention provides a photovoltaic mounting bracket for use in steep slope areas, comprising a first base, a first support member, a second support member, a second base, a first driving member, a mounting frame, and a plurality of third support members, wherein the first base is used to be fixed on the slope surface;

[0007] The lower ends of the first support member and the second support member are both rotatably connected to the first base, and the upper ends of the first support member and the second support member are both rotatably connected to the second base, so that the first base, the first support member, the second support member and the second base form a four-bar linkage, and the first driving member is connected to the second base;

[0008] The mounting frame is connected to the second base and is used to place photovoltaic modules; a plurality of third support members are arranged at intervals around the first base and are used to be fixed on the slope; the first driving member drives the second base to deflect toward the direction close to the slope, so that at least part of the periphery of the bottom surface of the mounting frame abuts against the upper end of the third support member.

[0009] In one possible implementation, the first driving member is a first telescopic member, one end of the first telescopic member is rotatably connected to the second base, and the other end of the first telescopic member is connected to the top of the slope facing away from the first base through a support, so that the second base deflects toward or away from the side above the slope.

[0010] In one possible implementation, a first locking mechanism is further provided between the bottom surface of the mounting frame and the upper end of the third support member, the first locking mechanism comprising a first latch, a housing, a locking member, and a second driving member, wherein the first latch is connected to the bottom surface of the mounting frame;

[0011] The housing is connected to the upper end of the third support member, and a first opening slot is formed on the housing to match the first latch; the locking member is disposed in the housing and moves relatively close to or away from the first opening slot, and the second driving member is connected to the locking member to drive the locking member to move;

[0012] When the bottom surface of the mounting frame abuts against the upper end of the third support member through the shell, the first latch is inserted into the first opening slot, and the second driving member drives the locking member to move toward the first opening slot so that the locking member abuts against the first latch and is locked.

[0013] In a possible implementation, the locking member is provided with a second opening slot matching the first latch pin, and the opening of the second opening slot faces one side of the first opening slot and is perpendicular to the opening direction of the first opening slot;

[0014] When the locking member abuts against the first latch, the first latch is engaged with the second opening slot.

[0015] In one possible implementation, the first latch has a first locking head on one end facing away from the mounting frame, and a first locking slope is provided on the side of the locking member facing away from the mounting frame;

[0016] When the second driving member drives the locking member to abut against the first latch, the first locking head abuts against the first locking inclined surface and moves relative to the first locking inclined surface to tighten the mounting bracket through the first latch.

[0017] In a possible implementation, a first limiting portion matching the locking member is provided in the housing, and the first limiting portion is slidably connected to the locking member.

[0018] In a possible implementation, the bottom surface of the mounting frame has a first abutting surface, the top surface of the shell has a second abutting surface abutting the first abutting surface, and a vibration damping pad is provided on at least one of the first abutting surface and the second abutting surface.

[0019] In a possible implementation, the device further includes a second locking mechanism, which is disposed between the first base and the second support member;

[0020] When the first driving member drives the second base to deflect in a direction away from the slope to an extreme position, the second locking mechanism is used to lock the first base and the second supporting member.

[0021] In one possible implementation, the second locking mechanism includes a slot, a second latch, and a third driving member, wherein the slot is provided on one of the first base and the second support member, and the second latch is movably provided on the other;

[0022] The third driving member is connected to the second latch and is used to drive the second latch to be inserted into the slot for locking.

[0023] In a possible implementation, the invention further includes a rock pile foundation, the rock pile foundation including an anchor hole, an anchor rod, embedded steel bars, embedded bolts, and a pier, wherein the anchor hole is used to be set in the lower layer of the rock, and the anchor rod is inserted into the anchor hole;

[0024] Embedded steel bars and embedded bolts are located above the anchor rods and cast to form the pier;

[0025] The upper part of the embedded bolt extends out of the pier and is connected to the first base.

[0026] The present invention provides a photovoltaic mounting bracket for use in steep slopes, comprising a first base, a first support member, a second support member, a second base, a first drive member, a mounting frame, and several third support members. The first base is fixedly mounted on the slope to provide basic support. The lower ends of the first and second support members are both pivotally connected to the first base, and the upper ends of the first and second support members are both pivotally connected to the second base, so that the first base, the first support member, the second support member, and the second base form a four-bar linkage. This allows the second base to be deflected toward or away from the slope to adjust its height relative to the slope. The first drive member is connected to the second base to drive the second base to deflect. The mounting frame is connected to the second base and used to mount photovoltaic modules. Several third support members are spaced around the first base and fixed to the slope. When the first drive member drives the second base to deflect toward the slope, at least a portion of the bottom surface of the mounting frame abuts against the upper ends of the third support members. The upper ends of the third support members provide stable support for the bottom surface of the mounting frame, improving vibration resistance. Therefore, the photovoltaic mounting bracket for steep slope areas provided by the present invention can deflect toward the direction close to the slope surface to lower the height when encountering extreme weather such as strong winds, and stably support the periphery of the bottom surface of the mounting bracket through the third support member to prevent the photovoltaic components from swaying with the wind, avoid or reduce damage to the photovoltaic components caused by swaying, and improve the photovoltaic components' ability to cope with extreme weather.

[0064] Exemplary embodiments will be described in detail herein, with examples illustrated in the accompanying drawings. In the following description, when referring to the drawings, like numbers in different figures represent like or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments are not intended to represent all possible embodiments consistent with the present invention. Rather, they are merely examples of methods and apparatus consistent with certain aspects of the present invention, as detailed in the appended claims.

[0065] The terms "first", "second", "third", "fourth", etc. (if any) in the description and claims of the present invention and the above-mentioned drawings are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that the numbers used in this way can be interchanged where appropriate, so that the embodiments of the invention described herein can, for example, be implemented in orders other than those illustrated or described herein. In addition, the terms "including" and "having" and any variations thereof are intended to cover non-exclusive inclusions, for example, a process, method, system, product or apparatus that includes a series of steps or units is not necessarily limited to those steps or units clearly listed, but may include other steps or units that are not clearly listed or inherent to these processes, methods, products or apparatus.

[0066] As mentioned in the background technology section, single-column photovoltaic mounts in related technologies lack support around the PV modules. When encountering extreme weather conditions such as strong winds, the PV modules shake significantly around the mounts. Generally, after repeated shaking, the PV modules fixed to the mounts tend to deform and loosen. In severe cases, the PV modules may fall off, causing damage. Therefore, single-column photovoltaic mounts have poor ability to withstand extreme weather conditions, and this problem needs to be addressed urgently.

[0067] In response to the above-mentioned problems existing in the prior art, the present invention provides a photovoltaic mounting bracket for steep slope areas. The photovoltaic mounting bracket for steep slope areas provided by the present invention includes a first base, a first support member, a second support member, a second base, a first drive member, a mounting frame, and a plurality of third support members. The first base is fixedly set on the slope surface to provide basic support. The lower ends of the first support member and the second support member are both rotatably connected to the first base, and the upper ends of the first support member and the second support member are both rotatably connected to the second base, so that the first base, the first support member, the second support member, and the second base form a four-bar linkage mechanism, so that the second base can be deflected in a direction closer to or away from the slope surface to adjust its height relative to the slope surface. The first drive member is connected to the second base to drive the second base to deflect. The mounting frame is connected to the second base, and the mounting frame is used to place the photovoltaic module. The plurality of third support members are spaced around the first base and fixed to the slope surface. When the first driving member drives the second base to deflect toward the slope, at least part of the periphery of the bottom surface of the mounting frame abuts against the upper end of the third support member. The upper end of the third support member is used to provide stable support for the periphery of the bottom surface of the mounting frame, preventing the photovoltaic components from swaying with the wind, avoiding or reducing damage to the photovoltaic components caused by swaying, improving vibration resistance, and thus improving the ability to cope with extreme weather.

[0068] The following specific embodiments of the present invention are described in detail with reference to the accompanying drawings. The following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be described in detail in some embodiments.

[0069] Reference Figures 1 to 6 As shown, the photovoltaic mounting bracket for steep slope areas provided in this embodiment includes a first base 100, a first support member 200, a second support member 300, a second base 400, a first driving member 500, a mounting frame 600 and several third support members 700, and the first base 100 is used to be fixed on the slope surface.

[0070] The lower ends of the first support member 200 and the second support member 300 are both rotatably connected to the first base 100, and the upper ends of the first support member 200 and the second support member 300 are both rotatably connected to the second base 400, so that the first base 100, the first support member 200, the second support member 300 and the second base 400 form a four-bar linkage mechanism, and the first driving member 500 is connected to the second base 400.

[0071] The mounting frame 600 is connected to the second base 400, and the mounting frame 600 is used to place the photovoltaic module 10; a plurality of third support members 700 are arranged at intervals around the first base 100 and are used to be fixed on the slope; the first driving member 500 drives the second base 400 to deflect toward the direction close to the slope, so that at least part of the periphery of the bottom surface of the mounting frame 600 abuts against the upper end of the third support member 700.

[0072] In this embodiment, the first base 100 is fixed to the foundation and is used to provide basic support for the first support member 200, the second support member 300, the second base 400, the mounting frame 600, and the photovoltaic module 10. The first base 100 can be fastened to the slope using piles, anchors, etc., and the slope can be about 30 degrees.

[0073] The first support member 200 and the second support member 300 are used to provide support for the second base 400, the mounting frame 600 and the photovoltaic component 10 thereon. The first support member 200 and the second support member 300 can be two equal-length support members (such as channel steel, I-beam, etc.). The first support member 200 and the second support member 300 are arranged in parallel. The lower ends of the first support member 200 and the second support member 300 are respectively rotatably connected to the first base 100 through a rotating shaft, and the upper ends of the first support member 200 and the second support member 300 are also respectively rotatably connected to the second base 400 through a rotating shaft. The axis of the rotating shaft is arranged horizontally so that the first base 100, the first support member 200, the second support member 300 and the second base 400 form a parallelogram four-bar linkage mechanism. In this way, when the second base 400 deflects toward the slope, the mounting frame 600 on the second base 400 will not deflect, that is, the inclination and azimuth of the photovoltaic component 10 will not change, but will only move from a higher position to a lower slope position, making it easier to restore to normal use next time.

[0074] The first driving member 500 is connected to the second base 400 and is used to drive the second base 400 to deflect toward or away from the slope. The first driving member 500 can be a telescopic member, one end of which is connected to the slope and the other end of which is connected to the second base 400. The first driving member 500 can also be another linear driving mechanism, as long as it can drive the second base 400 to deflect.

[0075] The mounting frame 600 is used to fix the photovoltaic assembly 10, that is, to fix multiple photovoltaic panels arranged in a rectangular array. The mounting frame 600 can be a frame structure. The mounting frame 600 can fix the periphery of the photovoltaic assembly 10 by bolts, pressure blocks and other components. The approximate middle position of the bottom surface of the mounting frame 600 can be fixedly connected to the second base 400 by a vertically arranged support rod.

[0076] The photovoltaic modules 10 on the mounting frame 600 can be mounted on the support pole in a fixed tilt and orientation. The mounting frame 600 can also be mounted on the support pole using a tilt adjustment mechanism and / or an orientation adjustment mechanism to adaptively adjust the tilt or orientation to follow the sun.

[0077] The third support members 700 are spaced around the first base 100 to support the bottom periphery of the mounting frame 600. The third support members 700 can be support columns, support members, etc. The bottom of the third support members 700 can be fixed on the slope by pile foundations, anchor rods, etc.

[0078] It should be noted that, since the mounting frame 600 is usually a rectangular structure, several third support members 700 should be arranged as close to the four corners of the rectangle as possible. That is to say, when the mounting frame 600 is deflected from a higher position toward a lower position close to the slope and abuts against the upper end of the third support member 700, the four corners of the mounting frame 600 can just be in contact with the upper end of each third support member 700. In this way, the mounting frame 600 is supported more stably.

[0079] Specifically, during normal use, the first support member 200 and the second support member 300 are in an upright position, and the second base 400 is relatively far from the slope, so that the mounting frame 600 and the photovoltaic module 10 are in the highest extreme position, so as to better receive sunlight for power generation. When encountering extreme weather such as strong winds, the first driving member 500 drives the second base 400 to deflect toward the slope, turning it to a lower position to reduce the impact of wind. In addition, part of the bottom surface of the mounting frame 600 is abutted against the upper end of the third support member 700. The third support member 700 supports the bottom surface of the mounting frame 600, thereby reducing the shaking and vibration of the photovoltaic module 10 thereon, and enhancing its wind resistance.

[0080] It should be noted that when an inclination adjustment mechanism or an azimuth adjustment mechanism is provided between the mounting frame 600 and the second base 400, before the mounting frame 600 deflects from a higher position toward the direction close to the slope, it needs to be adjusted to the initial position so that it can then abut and fit with the upper ends of each third support member 700.

[0081] It can be understood that, compared with the single-column photovoltaic bracket in the prior art, the photovoltaic mounting bracket for steep slope areas in this embodiment can deflect toward the direction close to the slope surface to reduce the height when encountering extreme weather such as strong winds, and the third support member 700 is used to provide stable support for the periphery of the bottom surface of the mounting frame 600 to prevent the photovoltaic component 10 from swaying with the wind, avoid or reduce damage to the photovoltaic component 10 caused by swaying, and make the photovoltaic component 10 have a stronger ability to cope with extreme weather.

[0082] In one possible design, Figure 1 、 6 As shown, the first driving member 500 is a first telescopic member, one end of the first telescopic member is rotatably connected to the second base 400, and the other end of the first telescopic member is connected to the top of the slope away from the first base 100 through the support 510, so that the second base 400 is deflected toward or away from the side above the slope.

[0083] The first telescopic member may be a cylinder, electric push rod, or the like. The telescopic end of the first telescopic member is connected to the upper portion of the second base 400 via a rotating shaft. The other end of the first telescopic member rotates with a support 510, which is secured to the upper portion of the slope facing away from the first base 100 via piles, anchors, or the like. The first support member 200 is located above the slope, while the second support member 300 is located below the slope. The upper ends of the first and second support members 200, 300, can simultaneously deflect toward the upper portion of the slope.

[0084] In this way, the inclination direction of the photovoltaic component 10 is basically consistent with the inclination direction of the slope. By shortening the first telescopic member, the second base 400, the mounting frame 600 and the photovoltaic component 10 can be slowly lowered to the side above the slope. By extending the first telescopic member, the second base 400, the mounting frame 600 and the photovoltaic component 10 can be slowly raised away from the slope, making the arrangement of the first telescopic member more reasonable and the force more stable.

[0085] It should be noted that the connection between the first telescopic member and the second base 400 should avoid the dead point position, that is, when the first telescopic member is extended and retracted so that the second base 400 is in the lowest position, the first telescopic member can still extend to drive the second base 400 to deflect upward.

[0086] In order to further improve the stability of the mounting frame 600 after contacting the third support member 700, as shown in FIG. Figure 1-Figure 3 As shown, in this embodiment, a first locking mechanism 800 is further disposed between the bottom surface of the mounting frame 600 and the upper end of the third support member 700. The first locking mechanism 800 comprises a first latch 810, a housing 820, a locking member 830, and a second driving member 840. The first latch 810 is connected to the bottom surface of the mounting frame 600. The housing 820 is connected to the upper end of the third support member 700. The housing 820 defines a first opening 821 that matches the first latch 810. The locking member 830 is disposed within the housing 820 and moves relative to or away from the first opening 821. The second driving member 840 is coupled to the locking member 830 to drive the locking member 830 to move. When the bottom surface of the mounting frame 600 abuts against the upper end of the third support member 700 through the shell 820, the first latch 810 is inserted into the first opening groove 821, and the second driving member 840 drives the locking member 830 to move toward the direction close to the first opening groove 821, so that the locking member 830 abuts against the first latch 810 and is locked.

[0087] In this way, the first locking mechanism 800 locks the periphery of the bottom portion of the mounting frame 600 to the upper end of the third support member 700, preventing it from detaching due to strong winds, reducing vibration impact, and preventing the bottom surface of the mounting frame 600 from colliding with the upper end of the third support member 700, thereby improving the stability of the locking.

[0088] Among them, the first locking mechanism 800 corresponds one-to-one to the third support member 700, the first pin 810 can be fixedly connected to the bottom surface of the mounting frame 600 perpendicular to the bottom surface of the mounting frame 600, the shell 820 is fixedly installed on the upper end of the third support member 700, and the first opening groove 821 on the shell 820 is opened along the deflection direction of the second base 400. The first opening groove 821 and the first pin 810 are clearance-matched to ensure that when the bottom surface of the mounting frame 600 abuts against the upper end of the shell 820, the first pin 810 can be inserted into the first opening groove 821.

[0089] The locking member 830 is movably connected within the housing 820 and moves in a direction toward or away from the first opening slot 821. The second driving member 840 can be a second telescopic member, such as an oil cylinder, a pneumatic cylinder, an electric push rod, etc. The second telescopic member is fixed to one side of the housing 820, and the telescopic end of the second telescopic member is connected to the locking member 830. When the first latch 810 is able to be inserted into the first opening slot 821, the second telescopic member drives the locking member 830 to move toward the first latch 810, abutting against the first latch 810 and locking it, thereby connecting the bottom surface of the mounting bracket 600 to the upper end of the housing 820 through the first latch 810.

[0090] It should be noted that, in order to further ensure the secure contact between the locking member 830 and the first latch 810, in some embodiments (not shown in the figures), a socket may be provided on one of the end of the locking member 830 close to the first latch 810 and the side wall of the first latch 810, and a plug matching the socket may be provided on the other of the two. When the locking member 830 abuts the first latch 810, the plug is inserted into the socket, thereby locking the locking member 830.

[0091] In other embodiments, Figure 3-Figure 4 As shown, in this embodiment, the locking member 830 is provided with a second opening slot 831 that matches the first latch 810. The opening of the second opening slot 831 faces one side of the first opening slot 821 and is perpendicular to the opening direction of the first opening slot 821. When the locking member 830 abuts the first latch 810, the first latch 810 and the second opening slot 831 are locked.

[0092] In this way, the first latch 810 can be locked by the engagement between the first latch 810 and the second opening slot 831. A limiting structure can also be provided between the inner wall of the second opening slot 831 and the outer wall of the first latch 810 to further prevent relative movement between the first latch 810 and the second opening slot 831.

[0093] Further, if Figure 5As shown, in this embodiment, the first latch 810 has a first locking head 811 on one end facing away from the mounting frame 600, and the locking member 830 is provided with a first locking slope 832 on the side facing away from the mounting frame 600. When the second driving member 840 drives the locking member 830 to abut against the first latch 810, the first locking head 811 abuts against the first locking slope 832 and moves relative to the first locking slope 832, thereby tightening the mounting frame 600 through the first latch 810.

[0094] The first locking head 811 is larger than the width of the second opening slot 831, meaning that the first locking head 811 cannot vertically pass through the second opening slot 831. Furthermore, in the vertical direction, the side of the first locking slope 832 closer to the first opening slot 821 is higher than the side away from the first opening slot 821.

[0095] In this way, when one or several places of the mounting frame 600 cannot abut against the shell 820 due to factors such as deformation of the periphery thereof (that is, when there is a small gap between one or several places on the bottom surface of the mounting frame 600 and the upper end of the shell 820), the second driving member 840 drives the locking member 830 to move closer to the first pin 810, and under the coordinated adjustment of the first lock head 811 and the first locking bevel 832, the bottom surface of the mounting frame 600 is gradually pulled close to the upper end of the shell 820, and the locking adaptability is better.

[0096] Furthermore, if Figure 3 As shown, in this embodiment, a first limiting portion 822 matching the locking member 830 is provided in the housing 820, and the first limiting portion 822 is slidably connected to the locking member 830. In this way, the locking member 830 can be moved and slid under the action of the first limiting portion 822.

[0097] Illustratively, the first limiting portion 822 may be a limiting hole provided in the housing 820 along the sliding direction of the locking member 830 , and the limiting hole matches the locking member 830 , thereby enabling the locking member 830 to slide back and forth in the limiting hole.

[0098] Of course, the first limiting portion 822 may also be a guide rail disposed within the housing 820 along the sliding direction of the locking member 830. The locking member 830 may be slidably connected to the guide rail via a guide groove, thereby enabling the locking member 830 to reciprocate and slide on the guide rail. The specific sliding structure between the first limiting portion 822 and the locking member 830 is not specifically limited in this embodiment.

[0099] Furthermore, in this embodiment, the bottom surface of the mounting frame 600 has a first abutting surface, the top surface of the shell 820 has a second abutting surface abutting the first abutting surface, and a vibration damping pad 823 is provided on at least one of the first abutting surface and the second abutting surface.

[0100] In this way, the bottom surface of the mounting frame 600 elastically contacts the top surface of the housing 820 via the vibration-damping pad 823, thus preventing damage caused by rigid contact. For example, the vibration-damping pad 823 can be made of a soft material such as rubber or silicone. The vibration-damping pad 823 can be fixedly connected to the second abutting surface on the top surface of the housing 820. This allows the vibration-damping pad 823 to cushion the contact between the first abutting surface and the second abutting surface of the bottom surface of the mounting frame 600, mitigating any rigid collision. A notch should also be left in the vibration-damping pad 823 at the location corresponding to the first opening slot 821 to prevent interference with the insertion of the first latch 810.

[0101] Alternatively, as Figure 1 、 Figure 2 、 Figure 6 As shown, this embodiment may also include a second locking mechanism 900, which is disposed between the first base 100 and the second support member 300. When the first driving member 500 drives the second base 400 to deflect away from the slope to the extreme position, the second locking mechanism 900 is used to lock the first base 100 and the second support member 300. This prevents the second support member 300 from deflecting, ensuring the stability of the photovoltaic assembly 10 during normal use.

[0102] Specifically, if Figure 1 、 Figure 2 As shown, in this embodiment, the second locking mechanism 900 may include a slot 910, a second latch 920, and a third driving member 930. The slot 910 is provided on one of the first base 100 and the second support member 300, and the second latch 920 is movably provided on the other. The third driving member 930 is connected to the second latch 920 and is used to drive the second latch 920 to insert into the slot 910 for locking.

[0103] Of course, the second locking mechanism 900 can also be replaced by other mechanisms with locking functions, as long as it can lock the first base 100 and the second support member 300, prevent the second support member 300 from deflecting, and can unlock when the second base 400 needs to be deflected. No excessive restrictions are made in this embodiment.

[0104] Optionally, the photovoltaic mounting bracket for steep slope areas provided in this embodiment may further include a rock pile foundation, wherein the rock pile foundation includes an anchor hole 110, an anchor 120, embedded steel bars 130, embedded bolts 140, and abutments 150. The anchor hole 110 is used to be set in the lower layer of the rock, and the anchor 120 is inserted into the anchor hole 110. The embedded steel bars 130 and the embedded bolts 140 are located above the anchor 120 and cast to form the abutments 150. The upper portion of the embedded bolts 140 extends out of the abutments 150 and is connected to the first base 100. In this way, the first base 100 can be firmly fixed to the exposed area of ​​the steep slope rock. Of course, the first drive member 500 and the third support member 700 can also be firmly fixed to the exposed area of ​​the steep slope rock using the above-mentioned rock pile foundation, and this is not excessively limited in this embodiment.

[0105] Specifically, such as Figure 1 As shown, three or more evenly distributed anchor holes 110 are first drilled downward on the steep rock. The depth of the anchor holes 110 can be within 1m, and the hole diameter can be 70mm to 90mm. A number of anchor rods 120 are inserted into the anchor holes 110 one by one. The embedded steel bars 130 are laid on the rock and can be connected to the upper ends of the anchor rods 120. Then, a plurality of embedded bolts 140 are vertically arranged above the embedded steel bars 130 and can be connected to them. Formwork is supported around the anchor holes 110, anchor rods 120, embedded steel bars 130, and embedded bolts 140, and grouting is performed to form the pier 150. The anchor holes 110 must also be filled with mortar. The pier 150 can also be a multi-level round or square table. The upper ends of the embedded bolts 140 must extend out of the pier 150 so as to be connected to the first base 100.

[0106] This arrangement ensures that the force on the first base 100 is transmitted to the rock at the bottom of the pile base to ensure the stability of the bracket. In addition, this arrangement facilitates manual on-site drilling and other construction, meeting the construction requirements of stably erecting the bracket in steep rocky areas, and has a wide range of applications.

The present invention is intended to cover any variations, uses, or adaptations of the present invention that follow the general principles of the invention and include common knowledge or customary techniques in the art not disclosed herein.
