Description

Technical Field

[0001] The present invention relates to the technical field of photovoltaic panel supports, and in particular to an outdoor solar photovoltaic panel support bracket. Background Art

[0002] Solar photovoltaic systems, also known as photovoltaics or simply PV, are facilities that convert solar energy into direct current electricity using the photovoltaic effect of photovoltaic semiconductor materials. The core of a photovoltaic facility is the solar panel.

[0003] The main reasons why solar photovoltaic panels require a specific tilt angle include improving sunlight reception efficiency, adapting to geographical differences, and optimizing power generation performance. In most cases, the optimal placement angle of solar photovoltaic panels is 45 degrees. This angle allows the photovoltaic panels to receive direct sunlight to a greater extent throughout the year, thereby improving power generation efficiency. The solar altitude angle in different regions varies significantly with latitude. For example, southern my country usually uses a 30° tilt angle, while the north needs to increase it to 45° to adapt to the lower solar altitude angle. Currently, when using solar photovoltaic panels outdoors, it is usually necessary to install the solar photovoltaic panels on a support bracket. Traditional support brackets are spliced ​​with several rods, bolts and waist holes. By adjusting the position of the bolts in the waist hole, the tilt angle of the solar photovoltaic panel can be adjusted.

[0004] However, the traditional support bracket has limited adjustment capabilities for the tilt angle of the solar photovoltaic panel, and during the adjustment process, the adjustment bolts on both sides need to be frequently turned for disassembly and assembly to achieve the angle adjustment effect. The operation is relatively cumbersome. When manually adjusting the tilt angle of the solar photovoltaic panel, if the tilt angle of the solar photovoltaic panel reaches the predetermined angle, there is no prompt function. It is necessary to manually measure the tilt angle of the solar photovoltaic panel multiple times. The tilt angle can only be fixed after the angle is determined, which makes it difficult to improve the adjustment efficiency of the tilt angle of the solar photovoltaic panel. Summary of the Invention

[0005] The purpose of the present invention is to address the defects and shortcomings of the existing technology and provide an outdoor solar photovoltaic panel support bracket that can provide a prompt after the angle of the photovoltaic panel is adjusted to a predetermined angle, eliminating the need for manual multiple measurements of the inclination angle of the solar photovoltaic panel.

[0006] To achieve the above-mentioned purpose, the present invention adopts the following technical solution: an outdoor solar photovoltaic panel support bracket, comprising a base, a square column arranged on the upper end surface of the base, a mounting plate arranged above the square column for mounting the solar photovoltaic panel, a hinge portion arranged between the upper end of the square column and the lower end of the mounting plate for allowing the mounting plate to rotate around the upper end of the square column, and also comprising two connecting blocks symmetrically arranged on the lower end surface of the mounting plate, an adjustment through-hole opened on the square column, an arc adjustment plate fixedly arranged on the two connecting blocks and passing through the adjustment through-hole, a limiting arc block arranged on the square column and located in the adjustment through-hole, and a hinge portion opened on the lower end surface of the arc adjustment plate, and A plurality of limiting arc grooves are arranged equidistantly in a ring and are used to engage with the limiting arc block when the mounting plate rotates to a predetermined angle around the upper end of the square column to increase the rotation resistance of the mounting plate; a lower clamping groove is provided on the square column and the limiting arc block; an upper clamping groove is provided in a ring at the lower end of the arc adjustment plate and is respectively connected with each limiting arc groove and is used to correspond to the position of the lower clamping groove when the limiting arc block is engaged with the limiting arc groove; a limiting rod is lifted and arranged on the square column and the limiting arc block and is located in the lower clamping groove and is clearance-matched with the upper clamping groove; a driving mechanism is provided between the limiting rod and the square column and is used to drive the limiting rod to rise and clearance-match with the upper clamping groove after the upper clamping groove corresponds to the position of the lower clamping groove to limit the movement of the arc adjustment plate.

[0007] Further improvements are: the driving mechanism includes a driving opening opened on the square column and connected to the lower slot, a rotating plate rotatably arranged in the driving opening and located below the limit rod for pushing the limit rod to rise and fit with the clearance of the upper slot when rotated to the vertical direction, and for allowing the limit rod to descend in the lower slot under its own gravity when rotated to the horizontal direction to disengage from the clearance fit with the upper slot, and a rotating part arranged between the rotating plate and the square column for driving the rotating plate to rotate to the vertical direction or the horizontal direction.

[0008] A further improvement is that the rotating member includes a rotating hole opened on the side end surface of the square column and connected to the driving opening, and a rotating rod rotatably arranged on the square column and located in the rotating hole, one end of the rotating rod is fixedly connected to the rotating plate, and the other end of the rotating rod is located on the outside of the square column.

[0009] A further improvement is that a rotating disk is provided at the other end of the rotating rod to facilitate manual control of the rotation of the rotating rod.

[0010] Further improvements are: the lower end face of the limit rod is an arc surface, and the upper and lower ends of the rotating plate are provided with matching arc surfaces for cooperating with the arc surface of the limit rod when the rotating plate is rotated to a vertical direction to increase the rotation resistance of the rotating plate; the left and right ends of the rotating plate are provided with side concave surfaces for increasing the descending space of the limit rod in the lower slot when the rotating plate is rotated to a horizontal direction; the side concave surfaces, matching arc surfaces and rotating plate are integrally formed.

[0011] A further improvement is that three arc-shaped elastic protrusions are provided in the driving opening on the square column for cooperating with the matching arc surface to increase the rotation resistance of the rotating plate when the rotating plate rotates to the vertical direction or the horizontal direction.

[0012] A further improvement is that the arc-shaped elastic protrusion is a rubber protrusion.

[0013] A further improvement is that an extension hole is provided on the side end surface of the square column, the extension hole is connected to the drive opening, the extension hole is a circular hole, and a closed block is provided on the square column in the extension hole.

[0014] A further improvement is that a threaded opening is provided on the rotating disk, the threaded opening is eccentrically arranged on the rotating disk, and a push bolt is threadedly connected in the threaded opening on the rotating disk.

[0015] After adopting the above technical solution, the beneficial effects of the present invention are as follows: the solar photovoltaic panel is fixedly mounted on the mounting plate by means of a clamp or fastener, when the inclination angle of the solar photovoltaic panel needs to be adjusted, force is applied to the mounting plate so that it rotates around the upper end of the square column through the hinge part, and the rotation of the mounting plate drives the arc adjustment plate to produce a position change in the adjustment perforation; when the mounting plate is rotated to a predetermined angle, the corresponding position of the limit arc groove is engaged with the limit arc block, thereby increasing the rotation resistance of the mounting plate on the square column, and prompting the operator to reach the predetermined angle; when the limit arc block is engaged with the limit arc groove, the upper and lower grooves are positioned correspondingly, and the limit rod is driven by the driving mechanism to rise in the lower groove and match the clearance of the upper groove, thereby limiting the movement of the arc adjustment plate; by fixing the arc adjustment plate, the inclination angle of the mounting plate is fixed; compared with the traditional support bracket, the angle adjustment effect can be achieved without frequently turning the adjustment bolts on both sides, the operation is relatively simple, and no angle measurement is required after the angle is adjusted, which can improve the efficiency of adjusting the inclination angle of the solar photovoltaic panel.

[0016] Further effects: when the rotating plate rotates to the vertical direction, the mating arc surface at one end of the rotating plate engages with the arc-shaped elastic protrusion located below; when the rotating plate rotates to the horizontal direction, the two mating arc surfaces at both ends of the rotating plate engage with the two arc-shaped elastic protrusions on both sides, thereby increasing the rotation resistance of the rotating plate, which can further prevent the rotating plate from rotating when it rotates on its own or is vibrated, and prevent the rotating plate from losing its fixing effect on the limit rod. After engagement, the resistance effect can remind the operator to rotate into place; when force is applied to rotate the rotating plate, the rotating plate squeezes the arc-shaped elastic protrusion to cause it to elastically deform, so that it can slide over the arc-shaped elastic protrusion and rotate to the next position.

[0017] Further effect: when the rotating plate is controlled to rotate to the vertical direction or the horizontal direction in the driving opening by the rotating disk, in order to maintain the directional state of the rotating plate and prevent the mounting plate or the solar photovoltaic panel from being rotated by factors such as wind or vibration, the resisting bolt can be screwed into the threaded opening of the rotating disk after the control is completed until one end of the resisting bolt resists the side end face of the square column. The resisting force can increase the rotational resistance of the rotating disk, thereby increasing the rotational resistance of the rotating rod and the rotating plate, and further allowing the rotating plate to remain in a fixed state.

DETAILED DESCRIPTION

[0028] The present invention will now be further described with reference to the accompanying drawings and specific embodiments.

[0029] See Figures 1 to 8 As shown, the technical solution adopted in this specific embodiment is: an outdoor solar photovoltaic panel support bracket, comprising a base 1, a square column 2 arranged on the upper end surface of the base 1, a mounting plate 3 arranged above the square column 2 for mounting the solar photovoltaic panel c1, a hinge portion arranged between the upper end of the square column 2 and the lower end of the mounting plate 3 for allowing the mounting plate 3 to rotate around the upper end of the square column 2, and also comprising two connecting blocks 4 symmetrically arranged on the lower end surface of the mounting plate 3, an adjustment through-hole 5 opened on the square column 2, an arc adjustment plate 6 fixedly arranged on the two connecting blocks 4 and passing through the adjustment through-hole 5, a limiting arc block 7 arranged on the square column 2 and located in the adjustment through-hole 5, and a lower end surface of the arc adjustment plate 6 and arranged equidistantly in a ring for mounting. When the plate 3 rotates to a predetermined angle around the upper end of the square column 2, it engages with the limiting arc block 7 to increase the rotation resistance of the mounting plate 3. There are several limiting arc grooves 8, lower clamping grooves 9 provided on the square column 2 and the limiting arc block 7, upper clamping grooves 10 provided in a ring shape at the lower end of the arc adjustment plate 6 and respectively connected with each limiting arc groove 8 for corresponding to the position of the lower clamping groove 9 when the limiting arc block 7 is engaged with the limiting arc groove 8, a limiting rod 11 which is lifted and lowered and is located in the lower clamping groove 9 on the square column 2 and the limiting arc block 7 and has a clearance fit with the upper clamping groove 10, and a driving mechanism provided between the limiting rod 11 and the square column 2, which is used to drive the limiting rod 11 to rise and have a clearance fit with the upper clamping groove 10 after the upper clamping groove 10 corresponds to the position of the lower clamping groove 9 to limit the movement of the arc adjustment plate 6.

[0030] The two connecting blocks 4 are fixedly connected to the lower end of the mounting plate 3 by welding, bonding or bolting. The circular position of the arc adjustment plate 6 is the same as or slightly deviates from the circular position of the hinge part. The number of the limiting arc grooves 8 can be set to three or three different numbers, such as Figure 2 and Figure 3 As shown, when there are three, one of the limiting arc grooves 8 is set at the vertical position between the arc adjustment plate 6 and the square column 2, specifically at the position corresponding to the limiting arc block 7 when the mounting plate 3 is in a horizontal state, and the other two are installed on the side of the arc adjustment plate 6, specifically at the position corresponding to the limiting arc block 7 when the mounting plate 3 is in an inclined position such as 45° or 30°. The limiting arc block 7 is set in advance according to the required inclination angle. When multiple limiting arc grooves 8 are set, the limiting arc grooves 8 are set according to the required inclination angle (such as 45°, 40°, 35°, 30°, 25°, 20°, etc.), so that after the mounting plate 3 is tilted to the corresponding angle, the limiting arc groove 8 can correspond to the position of the limiting arc block 7. The limiting arc block 7 is an arc protrusion made of plastic or hard material, and the limiting arc block 7 is fixed by welding or bonding or is integrally formed with the square column 2. The setting of the limiting arc groove 8 can not only increase the resistance of the arc adjustment plate 6 to the movement when cooperating with the limiting arc block 7, but also provide a sense of the angle being in place; when the angle needs to be adjusted, the pressure applied to the hand can make the limiting arc block 7 relatively easy to detach from the current limiting arc groove 8 by virtue of its arc surface, so as to slide into the next limiting arc groove 8, thereby preventing the limiting arc block 7 from being stuck in the limiting arc groove 8. The number of upper slots 10 is the same as the number of limiting arc grooves 8, and the position of each upper slot 10 is associated with the position of its corresponding limiting arc groove 8. The limiting rod 11 is a cylindrical rod or a square rod. In this case, the opening shape of the upper slot 10 and the lower slot 9 is a circular hole or a square hole corresponding thereto. The solar photovoltaic panel c1 is fixed to the mounting plate 3 by bolts, bonding, clamps, or clamps.

[0031] The hinged portion is provided at the lower end of the mounting plate 3 and at both sides of the square column 2 with two connecting plates a1. A connecting through-hole a2 is provided between the two connecting plates a1, and a matching through-hole a3 is provided at the upper end of the square column 2. The two mounting plates 3 are connected to the square column 2 through a connecting shaft a4. The connecting shaft a4 is clearance-matched with the connecting through-hole a2 and the matching through-hole a3. A limiting head a5 is provided at one end of the connecting shaft a4. The limiting head a5 is disc-shaped and has a diameter larger than the connecting through-hole a2. When the limiting head a5 abuts against one of the connecting holes, the limiting head a5 is provided. When the side end of the plate a1 is connected, a fixing nut a6 is threadedly provided at the other end of the connecting shaft a4. After installation, the fixing nut a6 is pressed against the side end face of the other connecting plate a1. At this time, the two connecting plates a1 can be installed on both sides of the square column 2. After assembly, a gap is left between the upper end face of the square column 2 and the lower end face of the mounting plate 3. The mounting plate 3 is rotated relative to the square column 2 by passing through the connecting shaft a4 that passes through the matching through-hole a3 and the connecting through-hole a2. The hinged portion can also adopt other structures that can realize the rotation of the mounting plate 3 around the square column 2.

[0032] The drive mechanism includes a drive opening 12 formed on the square column 2 and connected to the lower retaining groove 9; a rotating plate 13 rotatably disposed within the drive opening 12 and below the limiting rod 11, which is used to push the limiting rod 11 upward to form a clearance fit with the upper retaining groove 10 when rotated to the vertical direction, and to allow the limiting rod 11 to descend within the lower retaining groove 9 under its own weight to disengage from the clearance fit with the upper retaining groove 10 when rotated to the horizontal direction; and a rotating member disposed between the rotating plate 13 and the square column 2 for driving the rotating plate 13 to rotate vertically or horizontally. The drive opening 12 is a circular opening, with its upper end connected to the lower end of the lower retaining groove 9.

[0033] The rotating part includes a rotating hole 14 opened on the side end surface of the square column 2 and connected to the driving opening 12, and a rotating rod 15 rotatably arranged on the square column 2 and located in the rotating hole 14. One end of the rotating rod 15 is fixedly connected to the rotating plate 13, and the other end of the rotating rod 15 is located on the outside of the square column 2.

[0034] The other end of the rotating rod 15 is provided with a rotating disk 16 for facilitating hand control of the rotation of the rotating rod 15. The rotating disk 16 is driven by hand to drive the rotating rod 15 to rotate, and the rotating plate 13 is driven by the rotating rod 15 to rotate in the driving opening 12 to a vertical direction or a horizontal direction.

[0035] The lower end surface of the limiting rod 11 is an arc surface. The upper and lower ends of the rotating plate 13 are provided with matching arc surfaces 17 for cooperating with the arc surface of the limiting rod 11 when the rotating plate 13 rotates to the vertical direction to increase the rotation resistance of the rotating plate 13. The left and right ends of the rotating plate 13 are provided with side concave surfaces 18 for increasing the lowering space of the limiting rod 11 in the lower slot 9 when the rotating plate 13 rotates to the horizontal direction. The side concave surfaces 18, the matching arc surfaces 17, and the rotating plate 13 are integrally formed. Figures 5 to 7 As shown, the undercut surface 18 includes a central arc surface and inclined surfaces on both sides. When the rotating plate 13 rotates to the horizontal direction, the lower end of the limit rod 11 is attached to the arc surface. Chamfered transition surfaces b1 are provided at both ends of the mating arc surface 17.

[0036] Three arc-shaped elastic protrusions 19 are provided in the driving opening 12 on the square column 2 for cooperating with the matching arc surface 17 to increase the rotation resistance of the rotating plate 13 when the rotating plate 13 rotates to the vertical direction or the horizontal direction. The arc-shaped elastic protrusions 19 are rubber protrusions.

[0037] like Figure 5 and Figure 7 As shown, of the three arc-shaped elastic protrusions 19, two arc-shaped elastic protrusions 19 are symmetrically arranged on the left and right, and the other arc-shaped elastic protrusion 19 corresponds to the position of the limit rod 11. The arc-shaped elastic protrusion 19 is set as an arc surface, so that the contact resistance between the arc-shaped elastic protrusion 19 and the rotating plate 13 gradually increases and then gradually decreases during the rotation of the rotating plate 13. When the rotating plate 13 rotates to the horizontal position, the contact pressure between the two arc-shaped elastic protrusions 19 on both sides and the two ends of the rotating plate 13 is the largest. After a slight tilt, the contact pressure decreases. This can ensure the limiting force on the rotating plate 13 when it is in the horizontal position and make it easier for the rotating plate 13 to rotate after tilting. In order to increase the rotation resistance of the rotating plate 13, the arc-shaped elastic protrusion 19 can also be set as a plastic arc protrusion, such as a nylon arc protrusion, to reduce the deformation space of the arc protrusion and increase the rotation resistance.

[0038] An extension hole 20 is formed on the side end surface of the square column 2, communicating with the drive opening 12. The extension hole 20 is a circular hole, and a closing block 21 is positioned within the extension hole 20 on the square column 2. The closing block 21 is a circular block, with the same diameter as the drive opening 12. The closing block 21 is threaded into the extension hole 20, and includes a hexagonal or cross-shaped hole for easy tool insertion. When fully installed, the closing block 21 lies adjacent to a side surface of the rotating plate 13. The closing block 21 can also be a rubber block, snapping into the extension hole 20 through an interference fit. The extension hole 20, drive opening 12, and rotating hole 14 are integrally formed with the square column 2. The diameter of the extension hole 20 can be the same as that of the drive opening 12, interconnecting them. Alternatively, the diameter of the extension hole 20 can be larger than that of the drive opening 12, while still facilitating installation of the rotating plate 13. During assembly, first place the rotating plate 13 from the position of the extension hole 20 into the driving opening 12 so that it is located directly below the lower slot 9. Then, apply adhesive to one end of the rotating rod 15 and insert it from the rotating hole 14 so that one end of the rotating rod 15 is fixed to the side end of the rotating plate 13. Then, place the closing block 21 from the extension hole 20 to seal the extension hole 20 and limit the position of the rotating plate 13 in the driving opening 12. Then, place the limiting rod 11 from the position of the adjustment through-hole 5 into the lower slot 9 at an inclined angle, thereby completing the assembly process of this part.

[0039] A threaded opening 22 is formed on the rotating disk 16 . The threaded opening 22 is eccentrically disposed on the rotating disk 16 . A push bolt 23 is threadedly connected to the threaded opening 22 on the rotating disk 16 .

[0040] The working principle of the present invention is as follows: the solar photovoltaic panel c1 is fixedly mounted on the mounting plate 3 by means of a clamp or fasteners. When the tilt angle of the solar photovoltaic panel c1 needs to be adjusted, force is applied to the mounting plate 3 to rotate it around the upper end of the square column 2 through the hinge portion. The rotation of the mounting plate 3 drives the arc adjustment plate 6 to produce a position change in the adjustment perforation 5. When the mounting plate 3 is rotated to a predetermined angle, the limiting arc groove 8 at the corresponding position is engaged with the limiting arc block 7, thereby increasing the rotation resistance of the mounting plate 3 on the square column 2, which can prompt the operator to reach the predetermined angle. When the limiting arc block 7 is engaged with the upper card slot 10 of the limiting arc groove 8, the upper card slot 10 corresponds to the position of the lower card slot 9, and the hand controls the rotating disk 16 to rotate, so that the rotating rod 15 drives the rotating plate 13 to drive When the arc adjustment plate 6 is rotated to a vertical direction in the opening 12, the rotating plate 13 pushes the limit rod 11 to rise and fits with the clearance of the upper groove 10, thereby limiting the movement of the arc adjustment plate 6. By fixing the arc adjustment plate 6, the inclination angle of the mounting plate 3 is fixed. Compared with the traditional support bracket, there is no need to frequently screw the adjusting bolts on both sides to achieve the angle adjustment effect. The operation is relatively simple, and there is no need to measure the angle after adjusting the angle, which can improve the adjustment efficiency of the inclination angle of the solar photovoltaic panel c1. When it is necessary to release the fixation of the arc adjustment plate 6, the rotating disk 16 is controlled to rotate so that the rotating rod 15 drives the rotating plate 13 to rotate to a horizontal direction in the driving opening 12. At this time, the limit rod 11 drops in the lower groove 9 under its own gravity to break away from the clearance fit with the upper groove 10.

[0041] When the rotating plate 13 is rotated to the vertical direction, the matching arc surface 17 at one end of the rotating plate 13 is engaged with the arc-shaped elastic protrusion 19 located below. When the rotating plate 13 is rotated to the horizontal direction, the two matching arc surfaces 17 at both ends of the rotating plate 13 are engaged with the two arc-shaped elastic protrusions 19 on both sides, thereby increasing the rotation resistance of the rotating plate 13, and further preventing the rotating plate 13 from rotating when it rotates on its own or is vibrated, and preventing the rotating plate 13 from losing the fixing effect on the limit rod 11. After the engagement, the resistance effect can remind the operator to rotate to the right position. When force is applied to rotate the rotating plate 13, the rotating plate 13 squeezes the arc-shaped elastic protrusion 19 to cause it to produce elastic deformation, so that it can slide over the arc-shaped elastic protrusion 19 and rotate to the next position.

[0042] After the rotating plate 13 is controlled to rotate to a vertical or horizontal direction in the driving opening 12 by the rotating disk 16, in order to maintain the directional state of the rotating plate 13 and prevent the mounting plate 3 or the solar photovoltaic panel c1 from being rotated due to factors such as wind or vibration, the resisting bolt 23 can be screwed into the threaded opening 22 of the rotating disk 16 after the control is completed until one end of the resisting bolt 23 resists the side end surface of the square column 2. The resisting force can increase the rotation resistance of the rotating disk 16, thereby increasing the rotation resistance of the rotating rod 15 and the rotating plate 13, and further allowing the rotating plate 13 to remain in a fixed state.
