Description

Technical Field

[0001] This invention relates to photovoltaic module installation tools, and in particular to a device for adjusting the installation height of photovoltaic modules. Background Technology

[0002] Solar energy, as a clean energy source, is being used more and more widely, and photovoltaic (PV) panels are an important component of solar power generation equipment. PV panels are typically fixed to the top of a pile foundation using mounting brackets. Generally, four PV panels need to be connected as a group by horizontally installed purlins. The panels in the same group also need to be adjusted to the same horizontal plane to meet the installation requirements of the PV module. However, since the top of the pile foundation is about 2.5 to 3 meters above the ground, workers need to erect scaffolding or a high platform to operate, making the adjustment process extremely cumbersome and inefficient. Furthermore, adjusting the PV panels requires workers to manually lift and lower the PV modules, which weigh tens of kilograms, resulting in extremely high labor intensity and increasing the safety risks of working at height. In addition, the purlins used to connect the PV panels themselves have a certain degree of deformation error, which also affects the precision and accuracy of the workers' adjustments. Summary of the Invention

[0003] The purpose of this invention is to provide a device with a simple structure that can easily adjust the height of photovoltaic modules, thereby simplifying the operation complexity and improving the convenience, accuracy and safety of adjustment.

[0004] The photovoltaic module height adjustment device of the present invention includes a top support, a lifting cylinder and a base arranged sequentially from top to bottom; the base is fixedly installed on the top of the pile foundation, the top support is supported below the photovoltaic bracket, and a fixed screw tube and a supporting screw tube arranged vertically on the base and the top support respectively; the lifting cylinder is tubular and is screwed to the fixed screw tube and the supporting screw tube through internal and external threads respectively; the top support is equipped with a plurality of sleeves along the horizontal circumference, one end of the sleeve is hinged to the top support, and the other end of the sleeve has a sleeve hole.

[0005] Furthermore, there are mating threads between the outer wall of the fixed screw tube and the inner wall of the lifting cylinder, and between the outer wall of the lifting cylinder and the inner wall of the supporting screw tube.

[0006] Furthermore, the threads between the fixed screw tube and the lifting cylinder, and the threads between the lifting cylinder and the supporting screw tube, are arranged in opposite helical directions.

[0007] Furthermore, several magnets are installed at the bottom of the base.

[0008] Furthermore, the fixing screw is installed in the middle of the top surface of the base, and the top surface of the base is provided with several positioning holes along the circumferential direction at the side of the fixing screw; the bottom of the lifting cylinder is connected to a lifting plate extending laterally, and a positioning cylinder is provided on the lifting plate opposite to the positioning holes. The positioning cylinder has a through hole coaxial with the positioning hole, and a positioning pin is provided in the through hole of the positioning cylinder.

[0009] Furthermore, the side of the positioning cylinder has a through groove parallel to the axis, and the positioning cylinder has a horizontally arranged positioning groove at the top or middle of the through groove. The positioning pin is equipped with a pin handle that moves along the through groove, and the pin handle protrudes from the through groove and can be rotated and inserted into the positioning groove.

[0010] Furthermore, the sleeve is hinged to the top support via a rotating shaft, and the rotating shaft is axially horizontal.

[0011] Furthermore, the top support has an installation groove and an installation hole that connects to the installation groove. The end of the sleeve is set in the installation groove. The rotating shaft passes through the installation hole and the end of the sleeve. A stop plate that prevents the rotating shaft from moving axially is also installed in the installation hole.

[0012] Furthermore, the end of the sleeve is trumpet-shaped.

[0013] The photovoltaic module height adjustment device of this invention involves installing a photovoltaic bracket with photovoltaic panels on top of a pile foundation, and assuming a photovoltaic module height adjustment device between the top of the pile foundation and the photovoltaic bracket. The top support and bottom base of the device abut against the photovoltaic bracket and the pile foundation respectively, thereby forming vertical support. When it is necessary to adjust the height of the photovoltaic bracket and the photovoltaic panels on it, the lifting cylinder can be rotated relative to the base, or the top support can be rotated relative to the lifting cylinder. The relative lifting and lowering movement is achieved by utilizing the threads between the lifting cylinder and the fixed screw tube and the supporting screw tube, which in turn drives the lifting and lowering movement of the photovoltaic bracket until the photovoltaic bracket and the photovoltaic panels on it are adjusted to the required height. Then, the photovoltaic bracket is locked and fixed to the pile foundation. Its beneficial effects are as follows: This photovoltaic module height adjustment device has a simple structure and is easy to operate, which can effectively improve the work efficiency of adjustment operation; the device can achieve two-stage adjustment by the relative movement between the top support, the lifting cylinder and the base, and they are connected by threads, which has extremely high adjustment accuracy and can accurately adjust the photovoltaic panel to the required height; in addition, the top support is provided with multiple sleeves with openings along the circumference, and the operator can hold a long pole on the ground and insert one end of the long pole into the sleeve, thereby applying rotation operation to the top support on the ground, which greatly reduces the need for scaffolding or high platform construction and greatly improves the convenience and safety of operation.

[0030] This invention proposes a photovoltaic module height adjustment device.

[0031] In this embodiment of the invention, the photovoltaic module height adjustment device includes a top support 1, a lifting cylinder 2, and a base 3 arranged sequentially from top to bottom; the base is fixedly installed on the top of the pile foundation 10, the top support is supported below the photovoltaic bracket 20, and a fixed screw tube 4 and a supporting screw tube 5 arranged vertically on the base and the top support respectively; the lifting cylinder is tubular and is screwed to the fixed screw tube and the supporting screw tube respectively through internal and external threads; a plurality of sleeves 6 are installed on the top support in the horizontal circumferential direction, one end of the sleeve is hinged to the top support, and the other end of the sleeve has a sleeve hole 61.

[0032] like Figure 1-4 As shown, the photovoltaic module height adjustment device is installed between the pile foundation 10 and the photovoltaic support 20 to support the photovoltaic modules on the pile foundation. When it is necessary to adjust the height of the photovoltaic support and the photovoltaic panels on it, the operator stands on the ground and inserts one end of the long rod 30 into the sleeve. The operator can then apply a circumferential rotational force to the sleeve on the ground, thereby causing the lifting cylinder to rotate relative to the base, or the top support to rotate relative to the lifting cylinder. The relative lifting and lowering movement is achieved by using the threads between the lifting cylinder and the fixed screw tube and the supporting screw tube, thereby driving the lifting and lowering movement of the photovoltaic support until the photovoltaic support and the photovoltaic panels on it are adjusted to the required height. Then, the photovoltaic support is locked and fixed to the pile foundation.

[0033] The photovoltaic module height adjustment device described herein has mating threads between the outer wall of the fixing screw tube 4 and the inner wall of the lifting cylinder 2, and between the outer wall of the lifting cylinder and the inner wall of the supporting screw tube 5. This allows the lifting cylinder to fit over the fixing screw tube of the base, while the supporting screw tube fits over the lifting cylinder, forming a mating structure. This structure provides better waterproofing, thereby improving the service life of the photovoltaic module height adjustment device. Similarly, mating threads can also be provided between the inner wall of the fixing screw tube and the outer wall of the lifting cylinder, and between the inner wall of the lifting cylinder and the supporting screw tube, thus forming a connection structure where the fixing screw tube fits over the lifting cylinder and the lifting cylinder fits over the supporting screw tube. The specific selection can be set according to needs to meet specific usage requirements. In addition, the threads between the fixed screw tube 4 and the lifting cylinder 2, and between the lifting cylinder and the supporting screw tube 5, are set in opposite spiral directions. Thus, the operator can use a long rod to first drive the top support and the lifting cylinder to rotate and lift relative to the base simultaneously to achieve the first level of height adjustment. After the first level is adjusted to the appropriate height, the lifting cylinder and the base are fixed relative to each other. Then, the long rod is used again to drive the top support to rotate relative to the lifting cylinder in the opposite direction to achieve the second level of height adjustment, until the entire photovoltaic bracket is adjusted to the set height. Thus, by setting the opposite threads, multi-level adjustment can be easily achieved using the sleeve, which greatly improves the convenience of operation.

[0034] like Figure 5-7 As shown, the base can be fixed to the top of the pile foundation with screws, or several magnets 7 can be installed at the bottom of the base 3. This is because the pile foundation has embedded steel bars, and the base can be easily fixed to the pile foundation by setting the magnets, which greatly improves the convenience of operation and can also avoid damage to the pile foundation caused by screws. The fixing screw tube 4 is installed in the middle of the top surface of the base 3, and several positioning holes 31 are provided circumferentially on the side of the fixing screw tube on the top surface of the base; and the lifting cylinder 2, as Figure 8-9 As shown, a lifting plate 21 extending laterally is connected to its bottom. A positioning cylinder 22 is provided on the lifting plate opposite to the positioning insertion hole. The positioning cylinder has a through hole coaxial with the positioning insertion hole, and a positioning pin 8 is provided in the through hole of the positioning cylinder. When the lifting cylinder rises and falls relative to the base to the set height, the end of the positioning pin passes through the positioning cylinder and inserts into the positioning insertion hole, thereby fixing the lifting cylinder and the base relative to each other, completing the first stage of height adjustment; in addition, to facilitate the operation of the positioning pin, it can be... Figure 9 , 10As shown in Figure 11, a through groove 23 parallel to the axis is opened on the side of the positioning cylinder 22. The positioning cylinder is provided with a horizontally arranged positioning groove 24 at the top or middle of the through groove. The positioning pin 8 is equipped with a pin handle 81 that moves along the through groove. The pin handle protrudes from the through groove and can be rotated and inserted into the positioning groove. The operator can easily drive the positioning pin to rise and fall by turning the pin handle. When it is necessary to rotate the lifting cylinder, the operator can also easily rotate the positioning pin and insert the pin handle into the positioning groove, so that the positioning pin is kept away from the positioning hole.

[0035] like Figure 12 , 13 As shown, the sleeve 6 is hinged to the top support 1 via a rotating shaft 9, with the shaft axially horizontal. The top support 1 has a mounting groove 11 and a mounting hole 12 communicating with the mounting groove. The end of the sleeve 6 is positioned within the mounting groove, and the rotating shaft 9 passes through the mounting hole and the end of the sleeve, thus fixing the sleeve to the top support. Simultaneously, a stop piece 13 is installed in the mounting hole to prevent the rotating shaft from moving axially, thereby preventing the shaft from dislodging from the end of the sleeve. Furthermore, the end of the sleeve 6 can be flared to facilitate the insertion of long rods by workers.

[0036] The above description is merely a preferred embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent structural transformations made using the contents of the present invention's specification and drawings under the inventive concept of the present invention, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present invention.
