Description

Technical Field

[0001] The present invention relates to the technical field of photovoltaic bracket installation, and particularly relates to a positioning device for a photovoltaic panel bracket. Background Art

[0002] A photovoltaic panel bracket is a bracket used to fix a photovoltaic panel in a suitable position. In the prior art, the installation steps of a photovoltaic bracket include column installation, inclined beam installation, diagonal brace installation, purlin installation, and tie rod installation.

[0003] Among them, when installing purlins, if there are many photovoltaic panels installed side by side, the required purlins will be very long. Generally, there are at least three purlins distributed at the upper, middle, and lower positions of the bracket. Since the bracket is inclined and has a relatively high height, when installing the purlins at the middle and upper positions, usually multiple workers need to support at different positions of the purlin with tools similar to pitchforks at the same time, and then push the purlin along the inclined bracket to the middle and upper installation positions together. Such a too-long tool is not convenient to carry around, which increases the installation difficulty of the purlin and affects the overall installation efficiency. Therefore, corresponding improvements are made to solve this problem. Summary of the Invention

[0004] Based on the technical problems existing in the prior art, the present invention proposes a positioning device for a photovoltaic panel bracket.

[0005] A positioning device for a photovoltaic panel support proposed by the present invention includes adjacent two supports as a group and no less than three purlins simultaneously installed on multiple supports. The support includes a diagonal beam, and a long first column and a short second column are rotatably connected to the bottom of the diagonal beam. A plurality of uniformly distributed mounting holes are formed on both the first column and the second column. A first mounting sleeve is fixed to the bottom end of the top of the diagonal beam. A sliding opening is formed at the top of the diagonal beam, and two second mounting sleeves are arranged at the sliding opening. A sliding rod capable of inserting into the sliding opening is fixed to the bottom end of the second mounting sleeve. First round holes are formed in the middle part and the top part of the diagonal beam. Second round holes corresponding to the first round holes are formed on the sliding rod. A cylindrical section for a hook to hook is provided on the sliding rod. Each purlin is simultaneously fixed on a plurality of first mounting sleeves and second mounting sleeves that are on the same straight line. The device further includes a pre-fixing component. Before installing the support onto the sleeve, first insert the sliding rods at the bottom ends of the two second mounting sleeves into the sliding opening, then insert the hooks at one ends of two ropes into the openings at one end of the diagonal beam respectively, and then hook the two hooks onto the cylindrical sections on the two sliding rods respectively, so that one ends of the ropes are exposed outside. Then insert the first column and the second column into the corresponding sleeves respectively, raise the first column and the second column to a proper position, then drill holes in the sleeve through a drill bit, and then insert the bolt assembly into the sleeve and the mounting hole simultaneously, so as to fix the first column and the second column respectively, thus completing the installation of a group of supports. After all the supports are installed, place three purlins onto a plurality of first mounting sleeves and second mounting sleeves simultaneously, then fix the bottommost purlin to the first mounting sleeve through the bolt assembly, then several people simultaneously pull one of the ropes, and then the topmost purlin can be pulled to the topmost first round hole through the first group of second mounting sleeves. Then several people simultaneously pull the other rope, and then the middle purlin can be pulled to the middle first round hole through the other group of second mounting sleeves. The pre-fixing component will pre-fix the second mounting sleeve when the second mounting sleeve moves to the corresponding first round hole, and then insert the bolt assembly through the first round hole and the second round hole for installation, so as to fix each second mounting sleeve to the diagonal beam. Then fix the purlins to the second mounting sleeves through the bolt assembly in sequence, and finally remove the ropes from the sliding rods.

[0006] Preferably, the pre-fixing component includes a fixing ring fixed to the second column. After pulling the purlin to the predetermined position, tie the end of the rope to the corresponding fixing ring, and then the second mounting sleeve can be pre-fixed.

[0007] Preferably, the pre-fixing component includes a stop block disposed inside the inclined beam near the first round hole. A guide sleeve is provided on one side of the stop block, and a guide post is inserted into the guide sleeve. The other end of the guide post is fixed to the inner wall of the inclined beam. The stop block is connected to the inclined beam through a resilient component. An inclined surface capable of contacting the slide bar is provided on the stop block. When the purlin is pulled to near the predetermined position, the second mounting sleeve first pushes the stop block outward through the inclined surface. When the second mounting sleeve moves above the stop block, the resilient component will reset the stop block, and the second mounting sleeve can be pre-fixed by the stop block.

[0008] Preferably, the resilient component is a spring, and the stop block can be reset by the spring.

[0009] Preferably, the resilient component is a first magnet and a second magnet. The first magnet and the second magnet are distributed oppositely. The first magnet is fixed to the inner wall of the inclined beam, and the second magnet is fixed to the stop block. The stop block can be reset by the magnetic repulsion force between the first magnet and the second magnet.

[0010] Preferably, a counterbore is provided on the second mounting sleeve, and a shaft column is rotatably connected inside the counterbore. An anti-disengagement plate is fixed to the bottom end of the shaft column. In the initial state, the anti-disengagement plate is in a position parallel to the second mounting sleeve. When the slide bar is inserted into the slide opening, the shaft column is rotated until the anti-disengagement plate rotates to a position perpendicular to the second mounting sleeve, so that the second mounting sleeve can be prevented from disengaging from the slide opening of the inclined beam by the anti-disengagement plate.

[0011] Preferably, a pair of inclined braces with different lengths are rotatably connected to the bottom of the inclined beam. The other ends of the inclined braces are respectively rotatably connected to first hoop clamps. The two first hoop clamps are respectively fixed to the corresponding sleeves. After the bracket is installed, the two first hoop clamps are respectively fixed to two adjacent sleeves through bolt assemblies, and the stability of the bracket can be improved by the two inclined braces.

[0012] Preferably, a pair of cross-distributed diagonal struts between columns are further provided between two adjacent brackets. Second hoop clamps are respectively fixed to both ends of the diagonal struts between columns. The two second hoop clamps are respectively fixed to the corresponding second columns. After the brackets are installed, the two second hoop clamps are respectively fixed to two adjacent second columns through bolt assemblies, and the stability between two adjacent brackets can be improved by the two cross-distributed diagonal struts between columns.

[0013] Preferably, a plurality of tie rods are further provided between two adjacent purlins. Nuts respectively abutting against the two purlins are threadedly connected to both ends of the tie rod. The tie rod is passed through two adjacent purlins at the same time, and then the two nuts are respectively tightened to the ends of the tie rod, and the two adjacent purlins can be reinforced by the tie rod.

[0014] Compared with the prior art, the present invention provides a positioning device for a photovoltaic panel bracket, which has the following beneficial effects:

[0015] 1. A positioning device for a photovoltaic panel support. By providing a slidable second mounting sleeve, several people can simultaneously pull one of the ropes, and then the top purlin can be pulled to the top first circular hole through the first group of second mounting sleeves. Then, several people can simultaneously pull the other rope, and the middle purlin can be pulled to the middle first circular hole. The pre-fixing assembly will pre-fix the second mounting sleeve when the second mounting sleeve moves to the corresponding first circular hole. Finally, the rope can be removed from the sliding rod, making the installation of the purlin quite convenient and improving the installation efficiency.

[0016] 2. A positioning device for a photovoltaic panel support. By providing a fixing ring, after pulling the purlin to the predetermined position, the end of the rope can be tied to the corresponding fixing ring to pre-fix the second mounting sleeve.

[0017] 3. A positioning device for a photovoltaic panel support. By providing a stop block, when the purlin is pulled to near the predetermined position, the second mounting sleeve first pushes the stop block outward through the inclined surface. When the second mounting sleeve moves above the stop block, the two rebound components in this application will reset the stop block, and the second mounting sleeve can be pre-fixed through the stop block.

[0018] 4. A positioning device for a photovoltaic panel support. In the initial state, the anti-disengagement plate is in a position parallel to the second mounting sleeve. After inserting the sliding rod into the sliding opening and rotating the shaft column until the anti-disengagement plate rotates to a position perpendicular to the second mounting sleeve, the anti-disengagement plate can prevent the second mounting sleeve from disengaging from the inclined beam of the sliding opening.

Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments.

[0034] In the description of the present invention, it should be understood that the orientation or positional relationships indicated by the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc. are based on the orientation or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present invention.

[0035] Referring to Figure 1-13 , a positioning device for a photovoltaic panel support, comprising adjacent two supports as a group and not less than three purlins 23 installed on multiple supports at the same time. The support includes a diagonal beam 1, and a first upright column 2 and a second upright column 5 with one long and one short are rotatably connected to the bottom of the diagonal beam 1. A plurality of mounting holes 3 are evenly distributed up and down on both the first upright column 2 and the second upright column 5. A first mounting sleeve 6 is fixed to the bottom end of the top of the diagonal beam 1. A sliding opening 7 is formed at the top of the diagonal beam 1. Two second mounting sleeves 8 are arranged at the sliding opening 7. A sliding rod 9 capable of being inserted into the sliding opening 7 is fixed to the bottom end of the second mounting sleeve 8. First circular holes 10 are formed in the middle part and the top part of the diagonal beam 1. Second circular holes 11 corresponding to the first circular holes 10 are formed on the sliding rod 9. A cylindrical section for a hook 29 to hook is provided on the sliding rod 9. Each purlin 23 is simultaneously fixed to a plurality of first mounting sleeves 6 and second mounting sleeves 8 on the same straight line. It also includes a pre-fixing component. Before installing the support onto the sleeve 4, first insert the sliding rods 9 at the bottom ends of the two second mounting sleeves 8 into the sliding opening 7, then insert the hooks 29 at one ends of two ropes 28 into the openings at one end of the diagonal beam 1 respectively, and then hook the two hooks 29 onto the cylindrical sections on the two sliding rods 9 respectively, so that one end of the rope 28 is exposed outside. Then insert the first upright column 2 and the second upright column 5 into the corresponding sleeves 4 respectively, raise the first upright column 2 and the second upright column 5 to a proper position, then drill holes in the sleeve 4 through a drill bit, and then insert the bolt assembly into the sleeve 4 and the mounting hole 3 at the same time, so as to fix the first upright column 2 and the second upright column 5 respectively, thus completing the installation of a group of supports. After all the supports are installed, place the three purlins 23 onto a plurality of first mounting sleeves 6 and second mounting sleeves 8 at the same time, and then fix the lowermost purlin 23 to the first mounting sleeve 6 through the bolt assembly. Then several people pull one of the ropes 28 simultaneously, and the uppermost purlin 23 can be pulled to the uppermost first circular hole 10 through the first group of second mounting sleeves 8. Then several people pull the other rope 28 simultaneously, and the middle purlin 23 can be pulled to the middle first circular hole 10 through the other group of second mounting sleeves 8. The pre-fixing component will pre-fix the second mounting sleeve 8 when the second mounting sleeve 8 moves to the corresponding first circular hole 10. Then insert the bolt assembly through the first circular hole 10 and the second circular hole 11 for installation at the same time, so as to fix each second mounting sleeve 8 to the diagonal beam 1. Then fix the purlin 23 to the second mounting sleeve 8 through the bolt assembly in sequence. Finally, take the rope 28 off the sliding rod 9.

[0036] In Embodiment 1, the pre-fixing component includes a fixing ring 22 fixed on the second upright column 5. After pulling the purlin 23 to a predetermined position, tie the end of the rope 28 to the corresponding fixing ring 22, and the second mounting sleeve 8 can be pre-fixed.

[0037] In Embodiment 2, the pre-fixing component includes a stop block 13 disposed inside the inclined beam 1 near the first round hole 10. A guide sleeve 14 is provided on one side of the stop block 13. A guide post 12 is inserted into the guide sleeve 14, and the other end of the guide post 12 is fixed to the inner wall of the inclined beam 1. The stop block 13 is connected to the inclined beam 1 through a spring-back component. The stop block 13 is provided with an inclined surface capable of contacting the slide bar 9. When the purlin 23 is pulled to near the predetermined position, the second mounting sleeve 8 first pushes the stop block 13 outward through the inclined surface. When the second mounting sleeve 8 moves above the stop block 13, the spring-back component will reset the stop block 13, and the second mounting sleeve 8 can be pre-fixed by the stop block 13.

[0038] Among them, the spring-back component is a spring 15, and the stop block 13 can be reset through the spring 15.

[0039] In another embodiment, the spring-back component is a first magnet 16 and a second magnet. The first magnet 16 and the second magnet are distributed oppositely. The first magnet 16 is fixed to the inner wall of the inclined beam 1, and the second magnet is fixed to the stop block 13. The stop block 13 can be reset through the magnetic repulsion force between the first magnet 16 and the second magnet.

[0040] Further, a counterbore 17 is formed on the second mounting sleeve 8. A shaft column 18 is rotatably connected inside the counterbore 17. A retaining plate 19 is fixed to the bottom end of the shaft column 18. In the initial state, the retaining plate 19 is in a position parallel to the second mounting sleeve 8. When the slide bar 9 is inserted into the slide opening 7, the shaft column 18 is rotated until the retaining plate 19 rotates to a position perpendicular to the second mounting sleeve 8, so that the second mounting sleeve 8 can be prevented from detaching from the inclined beam 1 through the retaining plate 19.

[0041] Further, a pair of inclined braces 20 with different lengths are rotatably connected to the bottom of the inclined beam 1. The other ends of the inclined braces 20 are respectively rotatably connected to first hoop 21. The two first hoops 21 are respectively fixed to the corresponding sleeves 4. After the bracket is installed, the two first hoops 21 are respectively fixed to two adjacent sleeves 4 through bolt assemblies, and the stability of the bracket can be improved through the two inclined braces 20.

[0042] Further, a pair of cross-distributed diagonal struts 25 are also provided between two adjacent brackets. The two ends of the diagonal struts 25 are respectively fixed with second hoops 24. The two second hoops 24 are respectively fixed to the corresponding second columns 5. After the brackets are installed, the two second hoops 24 are respectively fixed to two adjacent second columns 5 through bolt assemblies, and the stability between two adjacent brackets can be improved through the two cross-distributed diagonal struts 25.

[0043] Further, a plurality of tie rods 26 are also provided between two adjacent purlins 23. Threaded connections are provided at both ends of each tie rod 26 with nuts 27 that abut against the two purlins 23 respectively. The tie rod 26 is passed through the two adjacent purlins 23, and then the two nuts 27 are tightened to the ends of the tie rod 26 respectively, so that the adjacent two purlins 23 can be reinforced by the tie rod 26.

[0044] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, makes equivalent substitutions or changes, and all should be covered within the protection scope of the present invention.
