Description

Technical Field

[0001] The invention relates to the technical field of photovoltaic brackets, and in particular to an adjustable flexible photovoltaic bracket for steep mountainous areas. Background Art

[0002] Flexible photovoltaic bracket is a large-span photovoltaic module support structure that is fixed at both ends and formed by a prestressed flexible cable structure. It adopts a tension structure system design and uses cables as component support members to form a large-span photovoltaic module support structure. Compared with rigid fixed brackets, flexible photovoltaic brackets have the advantages of large span, high clearance, and long column distance. Therefore, they are suitable for areas with complex terrain, such as mountains, valleys, pools, fish ponds, etc.

[0003] However, flexible photovoltaic brackets also have certain defects. Since all photovoltaic panels are set on steel cables, which are flexible structures, when encountering strong winds, the photovoltaic panels are likely to cause the steel cables to tilt to one side and swing accordingly due to the wind direction, which increases the burden on the steel cables and easily causes them to break or affect their service life. In addition, the steel cables are prone to breakage due to constant shaking. Therefore, it is necessary to provide a flexible photovoltaic bracket that can automatically adjust its own stability in windy weather. Summary of the invention

[0004] In order to solve the above technical problems, the present invention provides an adjustable flexible photovoltaic support for steep mountainous areas.

[0005] The present invention is implemented by the following technical scheme: two steel cable supports and two load-bearing cables built on the two steel cable supports, the steel cable supports include a frame-type support, a V-shaped wind plate is movably provided on the frame-type support, a cross frame is movably provided on the top of the frame-type support, a first steel cable frame and a rotatable second steel cable frame are respectively provided on the cross frame, and two suspension ropes cross-connected with the V-shaped wind plate are provided on the second steel cable frame, so that when the photovoltaic panel on the load-bearing cable tilts to one side due to the influence of wind, the V-shaped wind plate will also be affected by the wind and drive the second steel cable frame to reversely pull and adjust the load-bearing cable through the corresponding suspension rope.

[0006] As a further improvement of the above scheme, a screw is rotatably provided on the frame-type bracket, an internally threaded sleeve is threadedly sleeved on the screw, the cross frame is hinged to the frame-type bracket, and a sliding rod hinged to the internally threaded sleeve is telescopically installed on the cross frame, so that when two steel cable brackets are installed one above and one below on a mountain with a steep slope, the first steel cable bracket and the second steel cable bracket can make adaptive inclination adjustments.

[0007] As a further improvement of the above scheme, an internally threaded sleeve is provided on the threaded sleeve of the screw rod, and a direction-changing section frame is rotatably provided on the shaft rods at both ends of the V-shaped wind plate, one of the direction-changing section frames is fixedly connected to the frame-type bracket, and the other direction-changing section frame is telescopically connected to the internally threaded sleeve, so that the V-shaped wind plate can synchronously follow the first steel cable frame and the second steel cable frame to make tilt adjustments.

[0008] As a further improvement of the above scheme, a limiting plate is provided at one end of the shaft rod of the first steel cable rack, and a plurality of positioning grooves distributed in a ring are provided on the cross frame. A limiting bolt is threadedly installed on the limiting plate, and one end of the limiting bolt extends into the corresponding positioning groove, so that the first steel cable rack can not only maintain the limitation, but also adjust the angles of the two load-bearing cables and the photovoltaic panels installed on the two load-bearing cables as needed.

[0009] As a further improvement of the above solution, the V-shaped wind plate is provided with reinforcing ribs, so that the weight of the V-shaped wind plate can be maintained within a reasonable range while ensuring the strength of the V-shaped wind plate.

[0010] As a further improvement of the above solution, a plurality of water leakage holes are provided at the bottom of the V-shaped wind plate, so that rainwater falling into the V-shaped wind plate can be discharged smoothly.

[0011] As a further improvement of the above solution, two storage cavities are arranged in the V-shaped wind plate, and extension plates are slidably arranged in the two storage cavities, so that the wind receiving area of ​​the V-shaped wind plate can be adjusted according to needs.

[0012] As a further improvement of the above solution, an extension frame is hingedly installed on the second steel cable frame, and the extension frame consists of two extension rods and a V-shaped frame installed at one end of the two extension rods, thereby improving the control range of the second steel cable frame over the load-bearing cable.

[0013] As a further improvement of the above solution, two lifting rings are provided on both sides of the frame-type bracket, and pull ropes are connected to the four lifting rings, so as to improve the stability of the cable bracket.

[0014] Compared with the prior art, the present invention has the following beneficial effects: A new steel cable bracket is formed by the cooperation of the frame bracket, the V-shaped wind plate, the first steel cable rack and the second steel cable rack. Compared with the existing flexible bracket, it has a V-shaped wind plate. When the photovoltaic panel and the load-bearing cable are blown by the wind and tilt and shake, the V-shaped wind plate will also be blown by the wind, and the load-bearing cable will be pulled in the opposite direction through the suspension rope and the second steel cable rack, so that a stable balance is formed between the V-shaped wind plate and the two load-bearing cables, so as to achieve the purpose of adjusting the stability of the photovoltaic panel with the help of the wind direction; By arranging a limiting disk on the shaft of the first steel cable rack and arranging a plurality of positioning grooves distributed in an annular shape on the cross frame, the first steel cable rack can be limited by limiting bolts, so that when the two steel cable racks are at the same altitude, the tilt angle of the photovoltaic panel can be controlled by adjusting the rotation angle of the first steel cable rack on the two steel cable racks. When the steel cable rack serves as the middle support structure of the entire large-span flexible photovoltaic rack, it is only necessary to remove the limiting bolts on the limiting disk and install a suspension rope between the first steel cable rack and the V-shaped wind plate, so that the first steel cable rack can cooperate with the second steel cable rack to adjust the stability of the load-bearing cable and the photovoltaic panel, so that the steel cable rack has two uses, increasing its applicability. By setting two retractable extension plates on the V-shaped wind plate, the wind receiving area of ​​the V-shaped wind plate can be adjusted according to the span of the flexible bracket, so as to increase the wind resistance of the V-shaped wind plate. When the span of the flexible photovoltaic bracket is larger, the number of photovoltaic panels installed on it is relatively more, which also makes it more affected by the wind. Therefore, the wind receiving area of ​​the V-shaped wind plate needs to be adjusted according to actual needs; The extension frame composed of an extension rod and a V-shaped frame is mainly used as an additional part of the first and second steel cable frames in the steel cable bracket. Since the steel cable bracket serves as the end point support structure of the entire flexible photovoltaic bracket, its control over the load-bearing cables in the middle part is weak. By adding an extension frame, the control range of the load-bearing cables can be improved. BRIEF DESCRIPTION OF THE DRAWINGS

[0017] The present invention is further described below in conjunction with the accompanying drawings and specific implementation methods.

[0018] Please combine Figures 1 to 9 The adjustable flexible photovoltaic support for steep mountainous areas includes: two steel cable supports and two load-bearing cables 16 built on the two steel cable supports. The steel cable support includes a frame support 1. The frame support 1 consists of a base at the bottom and a frame at the top. The two parts are connected by bolts. The assembled structure makes the entire frame support 1 more convenient to transport. Two lifting rings 19 are arranged on both sides of the frame support 1. The four lifting rings 19 are connected with pull ropes 20, so as to improve the stability of the steel cable support. The frame support 1 A V-shaped wind plate 3 that can be adjusted and rotated is arranged on the frame bracket 1, a connecting seat is arranged on the top of the frame bracket 1, a cross frame 4 is hinged on the connecting seat, a screw rod 10 is rotatably arranged on the frame bracket 1, a turntable is arranged at the bottom end of the screw rod 10, an internal thread sleeve 12 is threadedly sleeved on the screw rod 10, and a sliding rod 13 hinged to the internal thread sleeve 12 is telescopically installed on the cross frame 4, so that when the two steel cable brackets are installed one above and one below on a mountain with a large slope, the first steel cable frame 5 and the second steel cable frame 8 can make adaptive inclination adjustments; An internal threaded sleeve 11 is threadedly sleeved on the screw rod 10, and a change-direction section frame 2 is rotatably sleeved on the shaft rods at both ends of the V-shaped wind plate 3. The change-direction section frame 2 is composed of an external frame body and a shaft sleeve rotatably installed in the frame body. One of the change-direction section frames 2 is fixedly connected to the frame bracket 1, and the other change-direction section frame 2 is telescopically connected to the internal threaded sleeve 11, so that the V-shaped wind plate 3 can synchronously follow the first steel cable frame 5 and the second steel cable frame 8 to make a tilt adjustment; A first steel cable frame 5 and a rotatable second steel cable frame 8 are respectively arranged on the cross frame 4, and two suspension ropes 9 cross-connected with the V-shaped wind plate 3 are arranged on the second steel cable frame 8, so that when the photovoltaic panel on the load-bearing cable 16 tilts to one side due to the influence of wind force, the V-shaped wind plate 3 will also be affected by the wind force and drive the second steel cable frame 8 through the corresponding suspension ropes 9 to reversely adjust the load-bearing cable 16.

[0019] Through the above technical solution, when the photovoltaic panel and the load-bearing cable 16 are blown by the wind and tilt and shake, the V-shaped wind plate 3 will also be blown by the wind, and the load-bearing cable 16 will be pulled in the opposite direction through the suspension rope 9 and the second steel cable frame 8, so that a stable balance is formed between the V-shaped wind plate 3 and the two load-bearing cables 16, so as to achieve the purpose of adjusting the stability of the photovoltaic panel with the help of the wind direction; When the two steel cable supports are installed at different altitudes in the mountains, the load-bearing cable 16 between the two is in a tilted state. At this time, in order for the two second steel cable supports 8 to better stably adjust the load-bearing cable 16, the load-bearing cable 16 between the two first steel cable supports 5 needs to remain in a non-turning state, and the two second steel cable supports 8 also need to be in position. Therefore, it is necessary to rotate the screw 10 through a turntable, and the screw 10 drives the V-shaped wind plate 3 and the cross frame 4 to tilt, and the cross frame 4 drives the first steel cable support 5 and the second steel cable support 8 to tilt, thereby completing the adaptive adjustment of the steel cable support.

[0020] Please combine Figure 4 A limiting plate 6 is provided at one end of the shaft rod of the first steel cable rack 5, and a plurality of positioning grooves 7 distributed in a ring are provided on the cross frame 4. A limiting bolt is threadedly installed on the limiting plate 6, and one end of the limiting bolt extends into the corresponding positioning groove 7, so that the first steel cable rack 5 can maintain the limitation and adjust the angles of the two load-bearing cables 16 and the photovoltaic panels installed on the two load-bearing cables 16 as needed.

[0021] Through the above technical scheme, when the two steel cable supports are at the same altitude, the inclination angle of the photovoltaic panel can be controlled by adjusting the rotation angle of the first steel cable support 5 on the two steel cable supports. When the steel cable support serves as the middle support structure of the entire large-span flexible photovoltaic support, it is only necessary to remove the limiting bolts on the limiting plate 6 and install a suspension rope 9 between the first steel cable support 5 and the V-shaped wind plate 3, so that the first steel cable support 5 can cooperate with the second steel cable support 8 to adjust the load-bearing cable 16 and the stability of the photovoltaic panel, so that the steel cable support has two uses, increasing its applicability.

[0022] Please combine Figure 7 The V-shaped wind plate 3 is provided with reinforcing ribs, so that the weight of the V-shaped wind plate 3 can be maintained within a reasonable range, and the strength of the V-shaped wind plate 3 can be ensured. A plurality of drainage holes are provided at the bottom of the V-shaped wind plate 3, so that rainwater falling into the V-shaped wind plate 3 can be discharged smoothly. Two storage cavities are provided in the V-shaped wind plate 3, and extension plates 14 are slidably provided in the two storage cavities, so that the wind receiving area of ​​the V-shaped wind plate 3 can be adjusted as needed. Two tightening bolts 15 are threadedly installed on the bottom of the V-shaped wind plate 3, which can be limited after the extension length of the extension plate 14 is adjusted.

[0023] Please combine Figure 4 An extension frame is hingedly installed on the second steel cable frame 8, and the extension frame consists of two extension rods 17 and a V-shaped frame 18 installed at one end of the two extension rods 17, so as to improve the control range of the second steel cable frame 8 on the load-bearing cable 16.

[0024] Through the above technical solution, the control range of the load-bearing cable 16 can be improved.

[0025] The implementation principle of an adjustable flexible photovoltaic support for steep mountainous areas in the embodiment of the present application is as follows: When encountering strong winds, the wind will simultaneously blow the photovoltaic panels installed on the load-bearing cables 16 and the V-shaped wind panels 3 on the two steel cable brackets. Therefore, the photovoltaic panels and the V-shaped wind panels 3 will tilt toward one side under the blowing of the wind. However, due to the restriction of the two cross-connected suspension ropes 9, the V-shaped wind panels 3 will pull the second steel cable bracket 8 in the direction through the corresponding suspension ropes 9 when tilting. Moreover, since the V-shaped wind panels 3 have a larger inclination angle, they are more affected by the wind force, so that the V-shaped wind panels 3, whose area is smaller than the total area of ​​all photovoltaic panels, can adjust the stability of the load-bearing cables 16 and the photovoltaic panels under the action of the wind force. Moreover, when the span of the load-bearing cable 16 is large, the cable bracket can also serve as a support frame for the middle section. When arranging, the cable bracket is placed in the middle section of the entire flexible photovoltaic bracket, and then the limiting bolts on the limiting plate 6 of the first cable bracket 5 are removed, so that the first cable bracket 5 can rotate like the second cable bracket 8, and the two suspension ropes 9 are also cross-connected between the first cable bracket 5 and the V-shaped wind plate 3, and then the extension frame is installed on the first cable bracket 5, so that the load-bearing cable 16 in the middle section can be supported when the span of the flexible photovoltaic bracket is large, so as to support it and achieve a better stabilizing and adjusting effect; When the two steel cable supports are installed at different altitudes in the mountains, the load-bearing cable 16 between the two is in a tilted state. At this time, in order for the two second steel cable supports 8 to better stably adjust the load-bearing cable 16, the load-bearing cable 16 between the two first steel cable supports 5 needs to remain in a non-turning state, and the two second steel cable supports 8 also need to be in position. Therefore, it is necessary to rotate the screw 10 through a turntable, and the screw 10 drives the V-shaped wind plate 3 and the cross frame 4 to tilt, and the cross frame 4 drives the first steel cable support 5 and the second steel cable support 8 to tilt, thereby completing the adaptive adjustment of the steel cable support.

[0026] The above-mentioned embodiments are only preferred embodiments of the present invention and cannot be used to limit the scope of protection of the present invention. Any non-substantial changes and substitutions made by technicians in this field on the basis of the present invention shall fall within the scope of protection required by the present invention.
