[0003] The existing photovoltaic support includes a base, a support frame and purlins. The support frame is installed and supported between the base and the purlins by fasteners. The purlins are used to install photovoltaic panels, and the two ends of the support frame that are far away from each other have a height difference so that the purlins are set tilted.
[0004] However, the inclination of the purlins requires that the photovoltaic panels be placed at an inclination before being connected to the purlins through connectors. This causes the photovoltaic panels to have a tendency to slide downward during installation, making it difficult to control their stability. Furthermore, when connecting the photovoltaic panels to the higher end of the purlins, the height affects the installation of the photovoltaic panels. Summary of the invention

DETAILED DESCRIPTION
[0025] The following is combined with Figure 1-9 This application is described in further detail.
[0026] The present application embodiment discloses a photovoltaic bracket for a photovoltaic power station. Figure 1 and Figure 2 The photovoltaic support for a photovoltaic power station includes a base 1, a support frame 2, a connecting rod 7 and a purlin 8.
[0027] The base 1 is cast by concrete mortar, and embedded parts 19 for connecting the support frame 2 are placed during the casting. The support frame 2 has two groups, the two groups of support frames 2 are parallel to each other, and are spaced apart in the horizontal direction, so that a width gap 3 is formed between the two groups of support frames 2. There are two purlins 8, the two purlins 8 are parallel to each other and correspond to the two groups of support frames 2 respectively. One end of the purlin 8 is hinged to one end of the corresponding support frame 2, and the other end of the purlin 8 is fixedly connected to the connecting rod 7, and the connecting rod 7 can adjust its own height on the support frame 2, so as to adjust the inclination angle of the purlin 8, and the photovoltaic panel (not shown in the figure) is installed on the two purlins 8 and the panel surface of the photovoltaic panel is parallel to the purlin 8, so as to adjust the inclination angle of the photovoltaic panel by adjusting the inclination angle of the purlin 8.
[0028] Reference Figure 2 Specifically, each support frame 2 includes a first support column 4, a second support column 5 and an adjustment frame 6. The first support column 4 and the second support column 5 are parallel to each other and have outer edges fixed to their peripheries. The first support column 4 and the second support column 5 are respectively inserted into the embedded parts 19 of the base 1. The embedded parts 19 have cavities for the support columns to be inserted, and the outer edges of the first support column 4 and the second support column 5 abut against the upper surface of the embedded parts 19 and are locked to the embedded parts 19 by bolts.
[0029] The top of the first support 4 is a hinged end, and the lower surface of one end of the purlin 8 is hinged to the hinged end of the first support 4 through a pin. The bottom of the adjustment frame 6 is fixed to the upper surface of the second support 5, and the height direction of the adjustment frame 6 extends along an arc shape, and the center of the arc trajectory of the adjustment frame 6 coincides with the hinge axis of the hinged end of the first support 4.
[0030] Reference Figure 2 and Figure 3 The adjustment frame 6 includes a side plate 61 and baffles 62 fixed on both sides of the side plate 61 away from each other. The side plate 61 and the baffle 62 extend along the circumferential trajectory of the adjustment frame 6 so that the cross section of the adjustment frame 6 is U-shaped with an opening toward the width gap 3, and the side plate 61 and the baffle 62 together enclose the active cavity 20.
[0031] The connecting rod 7 is in the shape of a round rod, and the two ends of the connecting rod 7 that are away from each other extend into the movable chambers 20 of the two adjustment frames 6 respectively. The lower surfaces of the two purlins 8 that are away from the first pillar 4 are fixed to the connecting rod 7. When the purlin 8 rotates around the hinged end of the first pillar 4, it drives the connecting rod 7 to move circumferentially along the adjustment frame 6 in the movable chamber 20 to adjust the inclination angle of the purlin 8. Among them, a stop block 21 is fixed at the bottom of the adjustment frame 6 in the movable chamber 20. When the connecting rod 7 moves to the bottom end of the adjustment frame 6 and abuts against the upper surface of the stop block 21, the purlin 8 extends in the horizontal direction. When the purlin 8 is in position, the photovoltaic panel is installed on the purlin 8.
[0032] After the photovoltaic panel is installed on the purlin 8, the purlin 8 and the photovoltaic panel are tilted by pushing the connecting rod 7 upward. In order to position the connecting rod 7 relative to the adjusting frame 6 when the connecting rod 7 reaches the set tilt position of the photovoltaic panel, a locking assembly 9 is provided on the connecting rod 7.
[0033] Reference Figure 2 and Figure 4 Specifically, the locking assembly 9 includes an insertion rod 91 and a linkage member 92. The insertion rod 91 is in the shape of a round rod, and has two insertion rods 91 that coaxially slide in the two ends of the connecting rod 7, and the insertion rod 91 has a first position and a second position corresponding to itself. When the insertion rod 91 is in the first position, the ends of the two insertion rods 91 that are away from each other extend out of the two ends of the connecting rod 7 respectively; when the insertion rod 91 is in the second position, the ends of the two insertion rods 91 that are away from each other are both recovered in the connecting rod 7.
[0034] The linkage member 92 includes a rotating portion 921 and a bidirectional screw 922. The rotating portion 921 is annular, and is coaxially rotatably connected to the middle of the connecting rod 7. The rotating portion 921 separates the connecting rod 7 into two sections along the axial direction, and the rotating portion 921 is rotatably connected between the two sections of the connecting rod 7. The rotating portion 921 is coaxially fixedly sleeved on the middle of the bidirectional screw 922, and the bidirectional screw 922 is coaxially located in the connecting rod 7. The outer diameter of the bidirectional screw 922 is smaller than the inner diameter of the connecting rod 7, and the threads at both ends of the bidirectional screw 922 are opposite.
[0035] The two plug rods 91 in the connecting rod 7 are respectively threadedly sleeved on the two ends of the bidirectional screw rod 922. At the same time, a guide block 22 is fixed on the outer wall of the plug rod 91, and a guide groove for the guide block 22 to slide is opened on the inner wall of the connecting rod 7 along the axis parallel to the inner wall of the connecting rod 7, so as to limit the rotation of the plug rod 91 relative to the connecting rod 7. Therefore, when the rotating part 921 is rotated, the bidirectional screw rod 922 can be driven to rotate synchronously, so that the two plug rods 91 move away from each other or closer to each other to the first position or the second position.
[0036] Reference Figure 3 and Figure 4 Furthermore, the adjustment frame 6 is provided with insertion holes 10 at intervals on its side plate 61, and the central angles of the two adjacent insertion holes 10 are consistent, and the insertion holes 10 are used for the insertion of the insertion rod 91. Specifically, when the connecting rod 7 moves in the movable cavity 20, the insertion rod 91 is adjusted to the first position. When the insertion rod 91 is opposite to the insertion hole 10, the rotating part 921 is rotated to adjust the insertion rod 91 to the second position, so that the insertion rod 91 can be inserted into the corresponding insertion hole 10. In addition, due to the arc curvature of the adjustment frame 6, when the wind blows toward the adjustment frame 6, it can be guided by the arc surface to disperse the wind force and improve the wind resistance.
[0037] Reference Figure 3 and Figure 5 Furthermore, a plurality of abutment sheets 11 are hingedly connected to the side plate 61 of the adjustment frame 6 facing the active cavity 20 along its own height direction through a pin shaft, and the rotation axis of the abutment sheet 11 extends along the radial direction of the adjustment frame 6, and the abutment sheets 11 and the jacks 10 are alternately arranged along the height direction of the adjustment frame 6, and the central angles between the rotation axes of each adjacent abutment sheet 11 are consistent. The abutment sheet 11 is used to guide, protect and buffer the connecting rod 7.
[0038] Reference Figure 5 and Figure 6 Specifically, the contact piece 11 is in the shape of an arc sheet, and each contact piece 11 includes a first portion 111 and a second portion 112 arranged in sequence from top to bottom, the first portion 111 and the second portion 112 are integrally formed, and the intersection of the first portion 111 and the second portion 112 is the center of the contact piece 11. The contact piece 11 is hinged to the side plate 61 by the second portion 112, the hinge point of the second portion 112 is closer to the side plate 61 than the end of the connecting rod 7, and the arc opening of the contact piece 11 faces the side plate 61.
[0039] Reference Figure 2 and Figure 7What's more, a pulling seat 12 is provided on the side of the side plate 61 away from the active cavity 20 and slides along its own circumferential direction. The cross-section of the pulling seat 12 is a U-shaped structure with an opening toward the side plate 61, and the pulling seat 12 has a limiting portion 23 that slides on the side plate 61. The limiting portion 23 is T-shaped, and a limiting groove 24 is provided on the side of the side plate 61 away from the active cavity 20 for the limiting portion 23 to move circumferentially along the adjusting frame 6, so as to guide the sliding of the pulling seat 12 while limiting the pulling seat 12 from separating from the side plate 61.
[0040] Reference Figure 6 and Figure 7 The first part 111 of each contact piece 11 is fixedly connected with a connecting rope 13, and the connecting rope 13 is slidably passed through the side plate 61 and fixed to the pulling seat 12. A reset member 14 is connected between the first part 111 of each contact piece 11 and the side plate 61. The reset member 14 is a spring and is located below the connecting rope 13. The reset member 14 gives the first part 111 an elastic force to rotate away from the side plate 61. The pulling seat 12 slides on the side plate 61 between its corresponding relaxation position and tightening position to drive the contact piece 11 to change its position.
[0041] Reference Figure 5 and Figure 7 Specifically, when the pulling seat 12 is in the relaxed position, a moving gap is left between the lower surface of the pulling seat 12 and the upper surface of the second column, and the end of the second part 112 of the abutting piece 11 away from the first part 111 abuts against the side plate 61, that is, the end of the second part 112 away from the first part 111 is not in the moving path of the connecting rod 7 in the active cavity 20, and at the same time, the end of the first part 111 away from the second part 112 is located in the moving path of the connecting rod 7.
[0042] Reference Figure 6 and Figure 7 When the pulling seat 12 moves from the release position to the tightening position, the lower surface of the pulling seat 12 abuts against the upper surface of the second column, and the pulling seat 12 pulls the connecting rope 13 downward to drive the abutting piece 11 to rotate until the end of the second part 112 away from the first part 111 leaves the side plate 61. At this time, the ends of the first part 111 and the second part 112 that are away from each other are not in the moving path of the connecting rod 7 in the active cavity 20, and there is an active gap 15 between the end of the first part 111 away from the second part 112 and the side plate 61, and the middle position of the first part 111 is in the moving path of the connecting rod 7 in the active cavity 20. When the pulling seat 12 moves upward from the tightening position to the release position again, the reset member 14 drives the abutting piece 11 to reset to the state where the second part 112 abuts against the side plate 61.
[0043] Reference Figure 2 , Figure 6 and Figure 7Among them, when the purlin 8 is in a horizontal position and the photovoltaic panel is installed, it is necessary to move the connecting rod 7 upward to the designed position, first adjust the pulling seat 12 to the loose position, and adjust the insertion rod 91 to the second position, and then push the connecting rod 7 upward. When the connecting rod 7 passes through the abutment piece 11 during the upward movement, the abutment piece 11 is pushed to rotate in the direction of the first part 111 toward the side plate 61. After leaving the abutment piece 11, the abutment piece 11 is reset under the push of the reset member 14.
[0044] When the connecting rod 7 reaches the required height position, the connecting rod 7 is first moved upward for a distance to reset the contact piece 11 below the connecting rod 7, and then the connecting rod 7 is moved downward to make the connecting rod 7 abut against the upper surface of the first part 111 of the contact piece 11 below itself. At this time, the plug rod 91 is opposite to the insertion hole 10. In this state, the plug rod 91 is adjusted to the first position, that is, the plug rod 91 can be inserted into the corresponding insertion hole 10. It should be noted that if the connecting rod 7 accidentally falls during the process of pushing the connecting rod 7 upward, the reset contact piece 11 below the connecting rod 7 can support the connecting rod 7, so that the connecting rod 7 is not easy to slide excessively, so as to protect the connecting rod 7, the purlin 8 and the photovoltaic panel.
[0045] When the position of the connecting rod 7 needs to be adjusted downward, the insertion rod 91 is first adjusted to the second position to release the positioning between the connecting rod 7 and the adjustment frame 6, and then the pulling seat 12 is adjusted to the tightening position. The pulling seat 12 will push the connecting rod 7 upward during the adjustment process. The connecting rod 7 can be moved upward and maintained before adjusting the pulling seat 12. After the pulling seat 12 is adjusted to the tightening position, the connecting rod 7 is pulled downward, and the connecting rod 7 passes through the abutment sheet 11 and is guided by the arc surface of the abutment sheet 11, thereby pushing the abutment sheet 11 to rotate in the direction of the first part 111 toward the side plate 61, so that the elastic force of the reset member 14 needs to be resisted during the downward movement of the connecting rod 7 to buffer the downward movement of the connecting rod 7, so that the connecting rod 7 is not easily impacted by moving downward too quickly due to gravity.
[0046] Reference Figure 2 and Figure 8 Furthermore, in order to move and position the pulling seat 12, a driving member 16 cooperating with the pulling seat 12 is provided on the side of the side plate 61 away from the active cavity 20. Fig. 9 Specifically, the driving member 16 includes a stud 161 and a driving column 162. The stud 161 (threads are not shown in the figure) is fixed to the side plate 61, and the axis of the stud 161 is parallel to the axis of the connecting rod 7. The driving column 162 is coaxially threadedly sleeved on the stud 161, a handle is fixed to one end of the driving column 162 away from the side plate 61, and the outer periphery of the driving column 162 is evenly spaced and fixed with first teeth 17 along its own circumference.
[0047] The second teeth 18 are evenly spaced and fixed along the circumference of the pull seat 12 on one side facing the driving column 162, and the second teeth 18 mesh with the first teeth 17. When the end of the driving column 162 close to the side plate 61 abuts against the side plate 61, the pull seat 12 is in a loose position. When the driving column 162 is threadedly moved away from the side plate 61, the engagement of the first teeth 17 and the second teeth 18 drives the pull seat 12 to move downward until the pull seat 12 abuts against the upper surface of the second pillar 5, and the pull seat 12 is in a tightened position.
[0048] The present application also discloses a method for installing a photovoltaic bracket in a photovoltaic power station, comprising the following steps: Step 1: Cast the base 1 by enclosing the template, and embed the embedded parts 19 in the base 1 during casting.
[0049] Step 2: After the base 1 is formed, the template is removed and the first support 4 and the second support 5 are connected to the embedded part 19 .
[0050] Step 3: Move the purlin 8 to a horizontal state, and then install the photovoltaic panel on the purlin 8.
[0051] Step 4: Push the connecting rod 7 upward until the photovoltaic panel reaches the set tilted position, and then adjust the insertion rod 91 to the first position and insert it into the insertion hole 10 to lock the connecting rod 7 and the adjustment frame 6.
[0052] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
