Description

Technical Field

[0001] This invention relates to the field of photovoltaic module support technology, specifically to a mounting bracket and method for rooftop distributed photovoltaic panels, and its application. Background Technology

[0002] A photovoltaic (PV) module is a power generation device that produces direct current (DC) electricity when exposed to sunlight. It consists of thin, solid-state photovoltaic cells made almost entirely of semiconductor materials, such as silicon. A PV module mainly includes a photovoltaic panel and a mounting bracket.

[0003] The mounting brackets used for rooftop distributed photovoltaic (PV) modules are mainly fixed structures, with the PV panels fixed to the top of the bracket and the bottom of the bracket bolted to the roof. For example, CN119254097A discloses a PV mounting bracket for rooftop PV panels, which, while enhancing the stability of the connection between the fixing screws and the roof, has the following problems:

[0004] 1) The photovoltaic mounting bracket is installed on the roof by installing multiple fixing screws through the guide groove on the L-shaped rotating rod. However, the roof is usually a cement or concrete structure. During the process of driving the screws into the roof, the roof cracks due to the stress, which leads to the problem of roof leakage.

[0005] 2) The photovoltaic panels are fixed at an angle and cannot be adjusted. This means that the photovoltaic panels cannot be adjusted according to changes in sunlight, resulting in low solar energy utilization. In addition, the roof is at a relatively high position relative to the ground. When there is strong wind, the tilted photovoltaic panels have greater wind resistance, which poses stability risks and noise problems. Summary of the Invention

[0006] The purpose of this invention is to provide a mounting bracket and method for rooftop distributed photovoltaic panels, which not only enables angle adjustment of rooftop photovoltaic panels, but also avoids the problem of roof cracks caused by using screws to fix the mounting bracket.

[0007] This invention is achieved through the following technical solution:

[0008] A mounting bracket for rooftop distributed photovoltaic panels, comprising:

[0009] Mounting racks are used to install photovoltaic panels;

[0010] A support assembly for supporting the mounting frame includes a pre-set fixed block and a support column; the pre-set fixed block is provided with a vertical groove and a strip through groove, the lower part of the vertical groove is connected to the strip through groove, the support column is slidably set in the vertical groove, and the top of the support column is movably connected to the mounting frame;

[0011] Each mounting bracket has a support component at each of its four corners;

[0012] An adjustment component is used to adjust the height of the support column. The adjustment component includes an adjustment block and a horizontal displacement component. The adjustment block corresponds one-to-one with the support column, and the surface of the adjustment block supporting the support column is inclined. The horizontal displacement of the adjustment block is used to push the support column to make vertical displacement. The horizontal displacement component is set between two support components and is used to push the two adjustment blocks to make horizontal linear displacement towards or away from each other. The two adjustment blocks are set in a mirror image.

[0013] Regarding the technology for adjusting the angle of photovoltaic panels, existing technologies typically involve setting a rotatable structure at the bottom of the mounting frame. While this rotatable structure can achieve angle adjustment of the photovoltaic panels, it also has the responsibility of bearing weight and adjusting the angle by rotating. This results in the contact point between the mounting frame and the bottom support being a rotatable position, which raises structural stability issues.

[0014] This invention involves setting a support component at each of the four corners of the mounting frame. The four support components are arranged in pairs. When the photovoltaic panel is tilted, the two support components at the high end of the photovoltaic panel form one pair, and the two support components at the low end of the photovoltaic panel form another pair. Therefore, the tilt angle of the photovoltaic panel can be adjusted by adjusting the height of the high-end or low-end support components. By using the height adjustment method of this invention to adjust the tilt angle of the photovoltaic panel, not only is the angle adjustment achieved, but the overall mounting frame structure also has good stability.

[0015] Furthermore, the present invention uses horizontal linear displacement to convert the vertical displacement of the support column, which will not cause the height of the mounting frame to increase. Moreover, the present invention can use the same horizontal displacement component to synchronously adjust the height of two support columns located in the same group, so as to ensure that the height of the two support columns located on the same side is consistent, further ensuring the stability of the mounting frame for installing photovoltaic panels.

[0016] The mounting bracket of this invention is not fixed to the ground with screws or the like. Instead, it uses pre-set fixing blocks to fix the support column. The pre-set fixing blocks are usually cement or concrete precast parts, which have the advantage of being heavy and can meet the stability requirements of the mounting bracket. This will not cause the cement floor of the roof to crack and leak due to the screws being driven in.

[0017] In summary, the mounting bracket of the present invention not only enables angle adjustment of photovoltaic panels installed on the roof, but also avoids the problem of roof cracks caused by using screws to fix the mounting bracket.

[0018] In a preferred embodiment, the horizontal displacement assembly includes a base, a motor, a first toothed plate, and a second toothed plate;

[0019] The motor's power output shaft is equipped with gears;

[0020] The first toothed plate is connected to one of the adjusting blocks via a first moving rod, and the second toothed plate is connected to another adjusting block via a second moving rod;

[0021] The first toothed plate and the second toothed plate mesh with the gear respectively. The first toothed plate and the second toothed plate are arranged opposite to each other and parallel on both sides of the gear. When the gear rotates, it drives the first toothed plate and the second toothed plate to move horizontally in opposite directions or in a straight line.

[0022] Both the first and second toothed plates have an L-shaped structure, and a rack is provided on the inner side of the horizontal section of the L-shaped structure.

[0023] The horizontal displacement component of the above-mentioned structure of the present invention can realize the synchronous displacement of two support columns, which not only achieves higher accuracy in adjusting the angle of the photovoltaic panel, but also makes the operation more convenient. Angle adjustment can be completed by using two horizontal displacement components through one mounting frame.

[0024] Furthermore, the horizontal displacement component of the above structure is simple, and the first toothed plate and the second toothed plate move synchronously with good stability. The vertical section of the L-shaped structure has a certain limiting effect on the horizontal movement of the first toothed plate and the second toothed plate.

[0025] In a preferred embodiment, the first toothed plate located below is slidably disposed on the base; or a limiting support is provided on the base, and the first moving rod and the second moving rod are slidably disposed on the limiting support.

[0026] The limiting support includes a column, the bottom of which is connected to the base, and a sleeve is provided at the top of the column. The first moving rod and the second moving rod are slidably disposed in the sleeve.

[0027] The above settings can further improve the stability of the horizontal displacement component.

[0028] In a preferred embodiment, the adjusting block is a wedge-shaped block, the inclined surface of which contacts the bottom of the support column, or the high and low ends of the inclined surface of the wedge-shaped block are provided with arc-shaped grooves, and the outer wall of the support column is provided with a connecting column that matches the arc-shaped grooves.

[0029] Wedge blocks are common structures used for height adjustment or linear reciprocating movement. The inclined surface of the wedge block allows for vertical displacement of the support column. Considering the optimal tilt angle of the photovoltaic panel, which can be calculated based on the installation location, the heights of the support columns corresponding to the high and low ends of the photovoltaic panel can usually be designed directly during installation. Therefore, this invention, when adjusting the photovoltaic panel angle, primarily considers adjusting the panel to a horizontal position during strong winds to reduce wind resistance and noise, and adjusting the tilt direction of the photovoltaic panel according to the direction of sunlight. For example, the tilt direction is different when the sun is rising and when it is setting, eliminating the need to constantly track the sun. Therefore, theoretically, the height of the support column in this invention can be set to two height points to achieve the purpose of this invention. To improve the stability of the wedge block when adjusting the height of the support column, arc grooves can be provided at both the high and low ends of the inclined surface of the wedge block. After adjustment to the designated position, the connecting column is locked within the arc groove, improving stability. However, the depth of the arc groove should not be too deep to avoid affecting the movement of the connecting column on the wedge block.

[0030] In a preferred embodiment, the support column is provided with a radially movable connecting column;

[0031] The adjusting block includes an adjusting plate with an adjusting groove. The adjusting groove has an inclined section, and the width of the adjusting groove is equal to the diameter of the connecting column.

[0032] Both ends of the adjustment groove are arc-shaped limiting grooves that cooperate with the connecting column.

[0033] The adjusting block of the present invention, when the support column makes vertical displacement, ensures that the connecting column always moves within the adjusting groove. Since the width of the adjusting groove is equal to the diameter of the connecting column, the adjusting groove always limits the movement of the connecting column, thus providing good stability. Furthermore, after the entire mounting bracket is assembled, since the connecting column is always placed within the adjusting groove and is connected to the support column, and the adjusting block is connected to the horizontal displacement component, the horizontal displacement component, the support component, and the mounting bracket are integrated into a single structure, thereby improving the structural stability of the entire mounting bracket.

[0034] In a preferred embodiment, the support column is a hollow circular tube, and the side wall of the circular tube is provided with a radial through groove for the connecting column to pass through.

[0035] The support column is equipped with a pushing mechanism for radial movement of the connecting column; the pushing mechanism includes a wedge plate, one end of the connecting column is slidably connected to the inclined surface of the wedge plate; the wedge plate is connected to a sliding push rod, the top of the sliding push rod is positioned near the top opening of the support column;

[0036] The top of the support column is open, and the bottom of the support column is closed.

[0037] Since the connecting column of the present invention is always placed in the adjustment groove, and the adjustment block can only move horizontally in the strip groove while the support column can only move vertically, it is crucial to achieve a structure in which the connecting column is always placed in the adjustment groove. If the connecting column is directly set on the outer wall of the support column, it is impossible to install the connecting column in the adjustment groove.

[0038] Therefore, the present invention provides a radially movable connecting column, and the vertical displacement of the pushing mechanism drives the connecting column to move radially. The installation process of the present invention is as follows:

[0039] First, move the adjusting block into the strip. Then, insert the support column downward into the vertical groove of the pre-set fixed block, and align the connecting column with the lower end of the adjusting groove. At this time, the connecting column does not protrude from the outer wall of the support column. Then, operate the pushing mechanism to make the connecting column move radially, extend out of the outer wall of the support column, and insert into the lower end of the adjusting groove, thus connecting the adjusting block and the support column. At this time, the horizontal displacement of the adjusting block can drive the vertical displacement of the support column.

[0040] In a preferred embodiment, the outer wall of the sliding push rod is an arc-shaped surface that mates with the inner wall of the circular tube, and the inner wall of the sliding push rod is connected to the wedge plate.

[0041] The above configuration enables the internal support column to guide and support the sliding push rod, which helps to improve the stability of the vertical displacement of the sliding push rod.

[0042] In a preferred embodiment, the top of the support column is detachably connected to a hinge, the hinge including a threaded post, which, when screwed in downward, pushes a sliding push rod downward, thereby causing the connecting post to extend out of the support column.

[0043] The top of the threaded column is movably connected to the mounting bracket.

[0044] In other words, the present invention is designed so that the hinge can not only realize the movable connection between the support column and the mounting bracket, but also provide a downward thrust for the sliding push rod to push the connecting column out of the support column.

[0045] In a preferred embodiment, the top of the threaded column is provided with two upright plates, and a shaft is provided between the two upright plates, with the bottom of the mounting bracket rotatably mounted on the shaft.

[0046] In a preferred embodiment, the adjusting block is slidably disposed at the bottom of the strip groove;

[0047] The bottom of the adjusting block is equipped with a slider, and the bottom of the strip groove is equipped with a slide rail.

[0048] The present invention utilizes an adjusting block that is slidably set at the bottom of the strip groove, which can not only meet the requirements for horizontal displacement of the adjusting block, but also prevent the bottom of the adjusting block from being suspended, that is, its bottom has a supporting function, which can improve the support stability of the support column for the mounting frame.

[0049] In a preferred embodiment, a guide tube is provided in the vertical groove, and the support column is slidably disposed in the guide tube;

[0050] The guide pipe passes vertically through the pre-set fixed pier, which is a precast cement component or a precast concrete component.

[0051] The guide tube provided by the present invention is more conducive to the vertical displacement of the support column. Preferably, the inner wall of the guide tube is in contact with the outer wall of the support column.

[0052] A method for using a photovoltaic panel mounting bracket includes the following steps:

[0053] In windy weather, when it is necessary to adjust the photovoltaic panel to be parallel to the ground, the horizontal displacement component located on the high side of the photovoltaic panel is controlled to push the adjustment block to move, so that the support column moves downward until the height of the support column is the same as the height of the support column on the low side of the photovoltaic panel.

[0054] The tilt direction of the photovoltaic panel can be adjusted by switching the high-end and low-end directions of the photovoltaic panel through the operation of two horizontal displacement components.

[0055] The tilt angle of the photovoltaic panel can be adjusted by manipulating the height difference between the support columns on both sides using two horizontal displacement components.

[0056] An application of a photovoltaic panel mounting bracket in installing photovoltaic panels on cement or concrete floors.

[0057] Compared with the prior art, the present invention has the following advantages and beneficial effects:

[0058] 1. The support column of the present invention is slidably mounted on a pre-set fixed pier, and its vertical height can be adjusted. The horizontal displacement component is used to push the adjustment block to move, and the adjustment block is used to support the support column. That is, the adjustment component of the present invention is used to realize the lifting and lowering of the support column on the one hand, and to connect two adjacent pre-set fixed piers on the other hand, so as to improve the overall structural stability. In other words, the present invention can use the weight of the pre-set fixed pier to ensure the stability of the mounting bracket, and can be fixed without the use of screws. The mounting bracket of the present invention is optimized for roof installation, and will not cause the cement floor of the roof to crack and leak due to the screws. It also has the advantage of structural stability while realizing angle adjustment.

[0059] 2. The horizontal displacement component of the present invention can not only realize the horizontal displacement of the adjustment block, but also the same horizontal displacement component can realize the synchronous adjustment of the vertical displacement of two support columns to ensure the stability of the photovoltaic panel tilt adjustment.

[0060] 3. The present invention optimizes the structure of the adjusting block and, with the addition of a radially displaceable connecting column, improves the overall structural stability and support stability of the mounting bracket. Attached Figure Description

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature.

[0088] Example 1:

[0089] To address the issue that existing rooftop photovoltaic panel 100 mounting brackets require screws driven into the concrete roof surface, which can easily lead to roof cracking, and to improve overall structural stability while allowing for angle adjustment of the photovoltaic panel 100, such as... Figures 1-12 As shown, this embodiment provides a rooftop distributed photovoltaic panel mounting bracket, including:

[0090] Mounting frame 1 is used to mount photovoltaic panels 100. Mounting frame 1 is existing technology and is composed of multiple intersecting angle steels. The photovoltaic panels 100 are mounted on top of mounting frame 1. In this embodiment, to achieve tilt adjustment of the photovoltaic panels 100, a fixing cylinder 11 is provided at the bottom of mounting frame 1. Multiple photovoltaic panels 100 can be mounted on the same mounting frame 1; that is, the tilt of multiple photovoltaic panels 100 can be adjusted simultaneously by adjusting the tilt of one mounting frame 1.

[0091] A support assembly is used to support the mounting frame 1. The support assembly includes a pre-set fixing block 2 and a support column 4. The pre-set fixing block 2 is a precast cement component or a precast concrete component. The pre-set fixing block 2 has the advantage of being heavy, and the support column 4 can be installed using bolts and screws. The pre-set fixing block 2 is placed directly below the mounting frame 1 without taking up more space. The pre-set fixing block 2 is provided with a vertical groove and a strip-shaped through groove 21. The lower part of the vertical groove is connected to the strip-shaped through groove 21. The support column 4 is slidably set in the vertical groove, and the top of the support column 4 is movably connected to the mounting frame 1. Specifically, in this embodiment, the movable connection is that a shaft 53 is set at the top of the support column 4, and the fixing cylinder 11 at the bottom of the mounting frame 1 is sleeved on the shaft 53.

[0092] The support component in this embodiment is used to support the mounting frame 1, and its height is adjustable, thereby adjusting the tilt of the mounting frame 1. Specifically, the support component consists of pre-positioned fixed blocks 2 at different fixed positions and a support column 4 capable of being raised and lowered. Preferably, a guide tube 3 is provided in the vertical groove, and the support column 4 is slidably disposed within the guide tube 3. The guide tube 3 preferably vertically penetrates the pre-positioned fixed block 2, and its top preferably protrudes beyond the pre-positioned fixed block 2 to facilitate the insertion of the support column 4. When installing the pre-positioned fixed block 2, a layer of wet concrete can be applied to the roof first, and then the bottom of the pre-positioned fixed block 2 can be placed on the wet concrete to improve its stability. When the guide tube 3 vertically penetrates the pre-positioned fixed block 2, a column can be cast on the roof first. During installation of the pre-positioned fixed block 2, the column is inserted into the guide tube 3 to further improve its stability. Preferably, the vertical groove is located at the center of the pre-positioned fixed block 2, and the strip-shaped through groove 21 is located on one side of the vertical groove.

[0093] Each mounting bracket 1 has a support component at each of its four corners; the four support components are grouped in pairs, with each pair corresponding to an adjustment component.

[0094] An adjustment assembly is used to adjust the height of the support column 4. The adjustment assembly includes an adjustment block 7 and a horizontal displacement assembly 6. The end of the adjustment block 7 is connected to the horizontal displacement assembly 6. The adjustment block 7 corresponds one-to-one with the support column 4. The surface of the adjustment block 7 that supports the support column 4 is inclined. The horizontal displacement of the adjustment block 7 is used to push the support column 4 to make vertical displacement. The horizontal displacement assembly 6 is set between the two support assemblies and is used to push the two adjustment blocks 7 to make horizontal linear displacement towards or away from each other. The two adjustment blocks 7 are set in a mirror image.

[0095] The installation process of the mounting bracket in this embodiment is as follows:

[0096] After the pre-set fixed pier 2 is installed in the designated position, a horizontal displacement component 6 is installed between the two pre-set fixed piers 2. The horizontal displacement component 6 is operated to make the adjusting blocks 7 on both sides move horizontally and linearly, so that the two adjusting blocks 7 enter the strip through groove 21 in the two pre-set fixed piers 2 respectively and move opposite to the vertical groove. Then the support column 4 is inserted into the vertical groove or guide tube 3. At this time, the adjusting block 7 supports the support column 4. Then the mounting frame 1 is installed on the top of the support column 4, and the photovoltaic panel 100 is installed on the mounting frame 1.

[0097] In this embodiment, a preferred structure of the horizontal displacement component 6 is as follows: it includes a base 61, a motor, a first toothed plate 65 and a second toothed plate 67; a gear 63 is provided on the power output shaft of the motor, the motor is mounted on the base 61, and the first toothed plate 65 located below is slidably disposed on the base 61.

[0098] The first toothed plate 65 is connected to one of the adjusting blocks 7 via the first moving rod 64, and the second toothed plate 67 is connected to the other adjusting block 7 via the second moving rod 66;

[0099] The first toothed plate 65 and the second toothed plate 67 mesh with the gear 63 respectively. The first toothed plate 65 and the second toothed plate 67 are arranged opposite to and parallel to the two sides of the gear 63. When the gear 63 rotates, it drives the first toothed plate 65 and the second toothed plate 67 to move horizontally in opposite directions or in a straight line.

[0100] Preferably, both the first toothed plate 65 and the second toothed plate 67 are L-shaped structures, and a toothed rack is provided on the inner side of the horizontal section of the L-shaped structure.

[0101] In this embodiment, the horizontal displacement component 6 is used to adjust the vertical height of the support column 4 in the following way:

[0102] like Figure 12 , Figure 13 As shown, Figure 12 The display shows the support column 4 at its lowest height. When it is necessary to raise the support column 4, the motor drives the gear 63 to rotate clockwise, causing the first toothed plate 65 and the second toothed plate 67 to move in opposite directions. This means the two adjusting blocks 7 move in opposite directions, moving the bottom of the support column 4 relative to the upper end of the inclined surface of the adjusting blocks 7. Since the support column 4 cannot move horizontally, it can only utilize the height difference of the inclined surfaces of the adjusting blocks 7. During this movement, the adjusting blocks 7 push the support column 4 upwards until it reaches the desired height. Figure 13 At the position shown, the height of support column 4 is relatively... Figure 12 The status of the display has improved.

[0103] The method of using the photovoltaic panel mounting bracket in this embodiment includes the following steps:

[0104] In normal use, photovoltaic panels 100 are installed at a slight angle, such as... Figure 1 As shown, Figure 1 The height of the left-hand support column 4 is higher than the height of the right-hand support column 4.

[0105] In windy weather, in order to reduce wind resistance and noise, the photovoltaic panel 100 needs to be adjusted to be parallel to the ground. This requires lowering the height of the left support column 4. The horizontal displacement component 6, located on the high side of the photovoltaic panel 100 (left side), pushes the adjustment block 7 to move downwards, so that the support column 4 moves downwards until the height of the support column 4 is the same as the height of the support column 4 on the low side of the photovoltaic panel 100 (right side).

[0106] If it is necessary to adjust the tilt of the photovoltaic panel 100 according to the rising and setting of the sun, or to adjust the angle of the photovoltaic panel 100 according to seasonal changes, the tilt direction of the photovoltaic panel 100 can be adjusted by operating the two horizontal displacement components 6 to switch between the high and low ends of the photovoltaic panel 100; for example: when... Figure 1 The state shown is the state of the sun rising. When the sun sets, the horizontal displacement component 6, located on the original high side (left side) of the photovoltaic panel 100, pushes the adjusting block 7 to move downward, so that the support column 4 moves downward until the height of the support column 4 is the same as the height of the support column 4 on the original low side (right side) of the photovoltaic panel 100. Then, the horizontal displacement component 6, located on the original low side (right side) of the photovoltaic panel 100, pushes the adjusting block 7 to move upward, so that the height of the support column 4 is the same as the height of the support column 4 on the original high side (left side) of the photovoltaic panel 100.

[0107] The tilt angle of the photovoltaic panel 100 can be adjusted by manipulating the two horizontal displacement components 6 to adjust the height difference of the support columns 4 on both sides; for example, if it is necessary to adjust the tilt angle of the photovoltaic panel 100 as follows: Figure 1 The tilt angle of the indicated state is increased, raising the height of the left support column 4 or lowering the height of the right support column 4. Under this condition, the position of the support column 4 on the inclined surface of the adjusting block 7 is not restricted, that is, the bottom of the support column 4 can fall at any position on the inclined surface of the adjusting block 7.

[0108] In this embodiment, in order to improve the structural stability and support stability of the mounting bracket, a preferred structure of the adjusting block 7 is as follows:

[0109] A radially movable connecting column 10 is provided on the support column 4. The support column 4 is a hollow circular tube, and the side wall of the circular tube is provided with a radial through groove 101 for passing through the connecting column 10. A U-shaped groove 31 corresponding to the radial through groove 101 is provided on the side wall of the guide tube 3. The open end of the U-shaped groove 31 is set downward, and the height of the U-shaped groove 31 can adapt to the path of the connecting column 10 when the support column 4 makes vertical displacement.

[0110] The adjusting block 7 includes an adjusting plate 71, on which an adjusting groove 72 is provided. The adjusting groove 72 has an inclined section, which is an inclined groove. The vertical height of the support column can be adjusted by utilizing the height difference between the high and low ends of the inclined section. The width of the adjusting groove 72 is equal to the diameter of the connecting column 10. In this embodiment, the adjusting groove 72 has a limiting function for the inserted connecting column 10 to ensure the stability of the connection between the support assembly and the adjusting assembly. When the height of the support column 4 is at its lowest state, the connecting column 10 is inserted at the low end of the adjusting groove 72. When the height of the support column 4 is at its highest state, the connecting column 10 is inserted at the high end of the adjusting groove 72. Preferably, both ends of the adjusting groove 72 are arc-shaped limiting grooves that cooperate with the connecting column 10.

[0111] To ensure that the connecting column 10 can be smoothly inserted into the adjusting groove 72, a pushing mechanism is provided inside the support column 4 to enable the connecting column 10 to move radially. The pushing mechanism includes a wedge plate 8, one end of the connecting column 10 is slidably connected to the inclined surface of the wedge plate 8, and the surface on which the connecting column 10 and the inclined surface of the wedge plate 8 are slidably connected is also an inclined surface. The wedge plate 8 is connected to a sliding push rod 9, and the top of the sliding push rod 9 is positioned near the top opening of the support column 4. The sliding push rod 9 can be moved downward by applying a pushing force to the top of the sliding push rod 9. The top of the support column 4 is an open end, and preferably, the bottom of the support column 4 is a closed end.

[0112] Preferably, the outer wall of the sliding push rod 9 is an arc-shaped surface that matches the inner wall of the circular tube, and the inner wall of the sliding push rod 9 is connected to the wedge plate 8.

[0113] Preferably, the adjusting block 7 is slidably disposed at the bottom of the strip groove 21; a slider 73 is provided at the bottom of the adjusting block 7, and a slide rail 22 is installed at the bottom of the strip groove 21, with the slider 73 and the slide rail 22 working together.

[0114] The installation process in this embodiment is as follows:

[0115] After the adjusting block 7 moves into the strip groove 21, the support column 4 is moved downwards until the connecting column 10 corresponds to the lower end of the adjusting groove 72. Then, a downward thrust is applied to the sliding push rod 9, and the connecting column 10 is pushed out of the support column 4 and inserted into the adjusting groove 72 by the downward movement of the wedge plate 8. The connecting column 10 is always placed in the radial groove 101. In the initial state, when the connecting column 10 does not protrude from the support column 4, the end of the connecting column 10 away from the wedge plate 8 is placed in the radial groove 101.

[0116] In this embodiment, the support column 4 is slidably disposed within the pre-set fixed block 2, and its vertical height can be adjusted. The horizontal displacement component 6 is used to push the adjustment 7 to move, while the adjustment block 7 is used to support the support column 4. That is, the adjustment component in this embodiment is used on the one hand to realize the raising and lowering of the support column 4, and on the other hand to connect two adjacent pre-set fixed blocks 2 to improve the overall structural stability. In other words, this embodiment can use the weight of the pre-set fixed block 2 to ensure the stability of the mounting bracket, and screws are not required for fixing. The mounting bracket in this embodiment will not cause the cement floor of the roof to crack and leak due to the screws being driven in, and it has the advantage of structural stability while realizing angle adjustment.

[0117] Example 2:

[0118] like Figure 14 As shown, this embodiment is based on Embodiment 1, and the difference between it and Embodiment 1 is that:

[0119] The specific structure of the adjusting block 7 is different. In this embodiment, the adjusting block 7 is a wedge block 74. The inclined surface of the wedge block 74 contacts the bottom of the support column 4. The height difference of the horizontal displacement of the wedge block 74 is used to adjust the height of the support column 4.

[0120] Preferably, the wedge block 74 has arc-shaped grooves 75 at both the high and low ends of its inclined surface, and the outer wall of the support column 4 has a connecting column 10 that matches the arc-shaped grooves 75.

[0121] Example 3:

[0122] This embodiment is based on Embodiment 1, but differs from Embodiment 1 in that the connection method between the first toothed plate 65 and the second toothed plate 67 and the base 61 is different. In this embodiment,

[0123] A limiting support 62 is provided on the base 61, and the first moving rod 64 and the second moving rod 66 are slidably disposed on the limiting support 62. Specifically, the limiting support 62 includes a column, the bottom of which is connected to the base 61, and a sleeve is provided on the top of the column. The first moving rod 64 and the second moving rod 66 are slidably disposed in the sleeve.

[0124] In this embodiment, the limiting support member 62 provides support for the first toothed plate 65 and the second toothed plate 67, thereby improving the overall structural stability of the horizontal displacement assembly 6.

[0125] Example 4:

[0126] This embodiment is based on embodiment 1, but differs from embodiment 1 in that the movable connection between the top of the support column 4 and the mounting bracket 1 is optimized. In this embodiment, the top of the support column 4 is detachably connected to a hinge 5. Specifically, the hinge 5 includes a threaded column 51, the outer wall of which is provided with an external thread, and the top of the support column 4 is provided with an internal thread. The hinge 5 and the support column 4 are connected by a thread. When the threaded column 51 is screwed down, it pushes the sliding push rod 9 down, thereby causing the connecting column 10 to extend out of the support column 4.

[0127] The top of the threaded column 51 is movably connected to the mounting bracket 1; the top of the threaded column 51 is provided with two upright plates 52, and a shaft 53 is provided between the two upright plates 52. The sleeve at the bottom of the mounting bracket 1 is rotatably mounted on the shaft 53. Preferably, the upright plate 52 is an arc-shaped plate, and the outer wall of the upright plate 52 protrudes from the outer wall of the threaded column 51. When the hinge 5 is screwed into the designated position, the bottom of the upright plate 52 contacts the top of the support column 4, and the outer wall of the upright plate 52 is flush with the outer wall of the support column 4.

[0128] The specific installation method in this embodiment is as follows:

[0129] After the adjusting block 7 moves into the strip groove 21, the support column 4 is moved downwards to a position where the connecting column 10 corresponds to the lower end of the adjusting groove 72. The hinge 5 is inserted into the top opening end of the support column 4 and screwed downwards. The downward screwing of the hinge 5 applies a downward thrust to the sliding push rod 9. By using the downward movement of the wedge plate 8, the connecting column 10 is pushed out of the support column 4. At this time, the bottom of the upright plate 52 contacts the top of the support column 4.

[0130] In this embodiment, the hinge 5 can both enable the top of the support column 4 to be movably connected to the mounting frame and apply a thrust to the radial movement of the connecting column 10.
