Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention. The present invention is further described below in combination with the embodiments.

[0054] The drag reduction system is movably arranged on the guide seat 8 and connected to the sliding seat 6. The roller seat 33 is connected to the sliding seat 6 to reduce the friction resistance during the tensioning process of the cable;

[0055] The drag reduction system comprises:

[0056] The rotating shaft 21 is movably arranged on the guide seat 8;

[0057] The drag reduction roller 16, a group of roller seats 33 are symmetrically arranged on the rotating shaft 21, a guide rod 29 connected to the roller seat 33 is movably arranged on the guide seat 8, and the drag reduction roller 16 is movably arranged on the roller seat 33;

[0058] The lubricating spraying assembly is arranged between the drag reducing roller 16 and the mounting seat 1 and is used for spraying lubricant onto the surface of the cable.

[0059] In a specific case of this embodiment, a resistance reducing member is provided between the sliding seat 6 and the fixing seat 10 to reduce the friction resistance between the sliding seat 6 and the fixing seat 10 .

[0060] It should be particularly noted that the resistance reducing member may be a ball or a roller 5 . In the present embodiment, the resistance reducing member is preferably a roller 5 , which is movably disposed on a sliding seat 6 and slidably cooperates with a fixed seat 10 .

[0061] In another specific case of this embodiment, the adjustment structure includes a power element and a No. 1 threaded rod 7, wherein the No. 1 threaded rod 7 is movably arranged on the fixed seat 10 and threadedly cooperates with the sliding seat 6, and the power element is arranged on the fixed seat 10 and its output end is connected to the No. 1 threaded rod 7.

[0062] Without limitation, the power element may be a stepper motor 9 or a servo motor. In the present embodiment, the power element is preferably a stepper motor 9, which is arranged on a fixing seat 10 and whose output end is connected to the No. 1 threaded rod 7. As for the specific model parameters of the stepper motor 9, the best choice can be made according to the actual situation, and no specific limitation is made here.

[0063] In actual application, the cable is passed through the guide seat 8 and placed on the guide roller 12, and then the cable and the photovoltaic panel are connected to realize the installation of the photovoltaic panel. The cable is controlled to be tensioned by the flexible bracket assembly to adjust the position or angle of the photovoltaic panel. During this process, the drag reduction roller 16 rotates on the rotating shaft 21, so that the friction resistance encountered during the tensioning process of the cable can be initially reduced. In this process, the lubricating spray assembly can be driven to spray lubricant on the surface of the cable, thereby further enhancing the smoothness of the cable during the tensioning movement. The controller 3 controls the stepper motor 9 to be powered on and rotated, driving the No. 1 threaded rod 7 to rotate synchronously. Under the action of the threaded cooperation between the No. 1 threaded rod 7 and the sliding seat 6, the sliding seat 6 and the drag reduction roller 16 are driven to move, thereby adjusting the position of the cable and changing the position of the photovoltaic panel.

[0064] See also Figure 1-Figure 5 As another preferred embodiment of the present application, the lubricating spray assembly comprises:

[0065] The material storage tank 2 is arranged on the mounting seat 1, the rotating shaft 21 is a hollow structure, and the material storage tank 2 is connected to the rotating shaft 21 through an organ pipe; and

[0066] The execution modules are in several groups and are arranged on the drag reducing roller 16 in a ring, and are used to spray the lubricant in the storage tank 2 onto the surface of the passing cable.

[0067] In this embodiment, each group of execution modules includes:

[0068] The movable plate 22 has one end hinged on the drag reduction roller 16 and a torsion spring is provided at the hinge. The drag reduction roller 16 is provided with a storage tank matched with the movable plate 22;

[0069] The nozzles 23 are multiple and are equidistantly arranged on the movable plate 22;

[0070] The airbag 26 is arranged between the storage tank and the movable plate 22. The airbag 26 is provided with an input hole and an output hole. Both the input hole and the output hole are provided with a one-way valve 27. The output hole is connected to the nozzle 23.

[0071] The flow channels 24 and the airbags 26 are the same in number and are arranged in a ring inside the drag reducing roller 16 . The flow channels 24 are connected to the input hole, and a through hole 36 connected to the flow channels 24 is formed on the rotating shaft 21 .

[0072] It should be supplemented that a plurality of discharge grooves 28 are arranged around the nozzle 23, and the discharge grooves 28 are in an arc shape.

[0073] It should be noted that the present embodiment is not limited to the above-mentioned execution module to input the lubricant in the storage tank 2 into the nozzle 23, and a centrifugal pump or a gear pump can also be used to directly drive it, which are not listed here one by one.

[0074] During the tensioning process of the cable, the friction resistance between the drag reducing roller 16 and the cable can drive the drag reducing roller 16 to rotate, so that the movable plates 22 at different positions contact the cable and are squeezed by the cable. The cable squeezes the movable plate 22, which can drive the movable plate 22 to rotate along its hinge and be stored in the storage groove 25, thereby squeezing the airbag 26. The squeezing of the airbag 26 can spray the lubricant in the glue storage tank from the nozzle 23. Since the discharge groove 28 is in an arc shape, the nozzle 23 can rotate in the process of spraying the lubricant, thereby expanding the spraying range of the lubricant, allowing the lubricant to fully contact the surface of the cable, reducing the friction resistance between the cable and the drag reducing roller 16, and further improving the smoothness of the flexible bracket assembly controlling the cable to perform tensioning movement to adjust the angle and position of the photovoltaic panel.

[0075] See also Figure 1 As another preferred embodiment of the present application, the device further comprises an auxiliary module, which is arranged on the guide seat 8 and is used to reduce the friction resistance between the cable and the guide seat 8; wherein

[0076] The auxiliary module comprises:

[0077] A slide bar 19 is movably arranged on the mounting seat 1 and located on one side of the drag reduction roller 16, and the slide bar 19 is elastically connected to the guide seat 8;

[0078] The auxiliary roller 20 is movably arranged inside the guide seat 8 and movably connected to the slide rod 19;

[0079] The adjusting arms 11 are arranged in a group and are symmetrically and movably arranged on the guide seat 8, and a guide roller 12 is movably arranged at one end of the adjusting arm 11;

[0080] A slider 14 is movably disposed on the guide seat 8, and the slider 14 is movably connected to the adjustment arm 11 through the pull arm 13;

[0081] The second threaded rod 15 is movably arranged on the guide seat 8 and movably connected to the slider 14 . A rotating handle is arranged at one end of the second threaded rod 15 .

[0082] It should be noted that the present embodiment is not limited to the aforementioned No. 2 threaded rod 15 to adjust the position of the slider 14 on the guide seat 8, and a linear motor or electric cylinder may also be used instead, which are not listed here one by one.

[0083] In actual application, by setting the guide roller 12, it is possible to avoid direct contact between the cable and the surface of the guide seat 8 when the cable passes through the guide seat 8, thereby reducing the friction resistance between the cable and the guide seat 8. At the same time, by setting the auxiliary roller 20, it is possible to adapt to cables of different thicknesses and avoid contact between the cable and the inner wall of the guide seat 8 during the tensioning process, thereby further improving the smoothness of the cable tensioning process. Later, by manually turning the handle, the No. 2 threaded rod 15 is driven to rotate, so that under the action of the threaded cooperation between the No. 2 threaded rod 15 and the sliding seat 6, the slider 14 is driven to move along the guide seat 8, so that under the action of the pulling arm 13, the adjusting arm 11 is driven to rotate along its hinge, so as to adjust the position of the guide roller 12 and change the angle between the cables on both sides of the drag reduction roller 16, so as to achieve fine-tuning of the position of the photovoltaic panel.

[0084] See also Figure 1 , Figure 6 , Figure 7 as well as Figure 8 As another preferred embodiment of the present application, the device also includes an anti-falling module, which is arranged between the guide seat 8 and the roller seat 33. When the adjustment structure works to adjust the position of the drag reduction roller 16, the adjustment structure simultaneously controls the anti-falling module to work and limits the cable.

[0085] In a specific case of this embodiment, the anti-falling module includes:

[0086] Side plates 17, which are in a group and symmetrically arranged on both sides of the drag reduction roller 16, and the side plates 17 are movably arranged on the roller seat 33 and the two are connected by an elastic member;

[0087] A plurality of rollers 18 are movably arranged in the through-window formed on the side plate 17 at equal intervals; and

[0088] The connecting arm 34 is movably connected between the side plate 17 and the guide seat 8 .

[0089] In another specific case of the present embodiment, a through groove 32 is formed on the guide rod 29, a conductive head 30 is provided on the guide seat 8, the conductive head 30 and the through groove 32 are slidably matched, a resistor bar 31 is provided on the inner wall of the through groove 32, the resistor bar 31 and the conductive head 30 are slidably matched, and the conductive head 30, the resistor bar 31 and the controller 3 are electrically connected.

[0090] It should be noted that the present embodiment is not limited to the above-mentioned conductive head 30 and resistor bar 31 to monitor the position of the drag reduction roller 16, and an infrared distance measuring sensor or a laser distance measuring sensor may be used instead, which are not listed here one by one.

[0091] In addition, the elastic member can be replaced by a spring 35, a spring sheet or an elastic steel plate structure. In the present embodiment, the elastic member is preferably a spring 35, and the spring 35 is connected between the side plate 17 and the roller seat 33. As for the specific model parameters of the spring 35, the best choice can be made according to the actual situation.

[0092] The stepping motor 9 drives the first threaded rod 7 to rotate, thereby controlling the sliding seat 6 and the drag reduction roller 16 to move relative to the guide seat 8. For example, when the drag reduction roller 16 Figure 6 As shown in the figure, when it moves to the right, the side plate 17 on the left side of the drag reduction roller 16 can be driven to move upward under the action of the connecting arm 34, thereby limiting the left side of the cable to prevent the cable and the surface of the drag reduction roller 16 from being separated under the action of tension when the drag reduction roller 16 moves, and at this time, the conductive head 30 is driven to move synchronously, and the position of the conductive head 30 on the resistor bar 31 is fed back to the controller 3. The staff can obtain the precise position of the drag reduction roller 16 according to the data displayed on the controller 3, which is convenient for the staff to control the stepper motor 9 through the controller 3.

[0093] How this application works:

[0094] The photovoltaic panel can be installed by passing the cable through the guide seat 8 and laying it on the guide roller 12, and then connecting the cable and the photovoltaic panel. The position or angle of the photovoltaic panel can be adjusted by controlling the cable to be tensioned through the flexible bracket assembly. During this process, the drag reduction roller 16 rotates on the rotating shaft 21, so that the friction resistance encountered during the tensioning process of the cable can be initially reduced. During the tensioning process of the cable, the friction resistance between the drag reduction roller 16 and the cable can drive the drag reduction roller 16 to rotate, so that the movable plates 22 at different positions are in contact with the cable and are affected. The squeezing effect of the cable, the cable squeezing the movable plate 22 can drive the movable plate 22 to rotate along its hinge and be stored in the storage groove 25, thereby squeezing the airbag 26. The squeezing of the airbag 26 can spray the lubricant in the glue storage tank from the nozzle 23. Since the discharge groove 28 is in an arc shape, the nozzle 23 can rotate in the process of spraying the lubricant, thereby expanding the spraying range of the lubricant, allowing the lubricant to fully contact the surface of the cable, reducing the friction resistance between the cable and the drag reduction roller 16, and further improving the smoothness of the flexible bracket assembly to control the tensioning movement of the cable to adjust the angle and position of the photovoltaic panel. The stepper motor 9 drives the No. 1 threaded rod 7 to rotate to control the sliding seat 6 and the drag reduction roller 16 to move relative to the guide seat 8. For example, when the drag reduction roller 16 is Figure 6 As shown in the figure, when it moves to the right, the side plate 17 on the left side of the drag reduction roller 16 can be driven to move upward under the action of the connecting arm 34, thereby limiting the left side of the cable to prevent the cable and the surface of the drag reduction roller 16 from being separated under the action of tension when the drag reduction roller 16 moves, and at this time, the conductive head 30 is driven to move synchronously, and the position of the conductive head 30 on the resistor bar 31 is fed back to the controller 3. The staff can obtain the precise position of the drag reduction roller 16 according to the data displayed on the controller 3, which is convenient for the staff to control the stepper motor 9 through the controller 3. By setting the guide roller 12, it is possible to avoid direct contact between the cable and the surface of the guide seat 8 when the cable passes through the guide seat 8, thereby reducing the friction resistance between the cable and the guide seat 8. At the same time, by setting the auxiliary roller 20, it is possible to adapt to cables of different thicknesses and avoid contact between the cable and the inner wall of the guide seat 8 during the tensioning process, thereby further improving the smoothness of the cable tensioning process. Later, the handle is manually rotated to drive the second threaded rod 15 to rotate, so that under the action of the thread cooperation between the second threaded rod 15 and the sliding seat 6, the slider 14 is driven to move along the guide seat 8, so that under the action of the pulling arm 13, the adjusting arm 11 is driven to rotate along its hinge, so as to adjust the position of the guide roller 12 and change the angle between the cables on both sides of the drag reduction roller 16, so as to achieve fine adjustment of the position of the photovoltaic panel.
