Abstract

The application discloses a photovoltaic module with windproof function, and particularly relates to the technical field of photovoltaic modules. Four photovoltaic side plates are arranged around the outer side of a counterweight base. A power switching unit is connected with an adjusting unit in meshing mode. The four photovoltaic side plates rotate synchronously around the hinge points at the bottom and the base. The overall angle of the photovoltaic side plates is adjusted simultaneously according to wind force, and the consistency of light utilization is ensured. When the power switching unit is lowered, the power switching unit is connected with a plug-in unit. The plug-in rod is pushed by a synchronous electric cylinder on a pushing part, so that the plug-in rod is deflected around the hinge point of a lower sleeve base. The plug-in rod is reliably locked under the cooperation of the plug-in rod and a positioning groove, and a stable surrounding multi-direction wind resistance structure is formed. When external wind force acts from different directions, the photovoltaic side plates can maintain stable angles, and shaking, deviation or falling is avoided due to wind pressure concentration. The self-weight of the counterweight base further enhances the stability of the whole, so that the wind impact is effectively resisted.

DETAILED DESCRIPTION

[0040] In order to further illustrate the technical means and effects adopted by the present application to achieve the predetermined object of the application, the specific embodiments, structures, features and effects according to the present application are described in detail below in combination with the drawings and preferred embodiments.

[0041] Please refer to Figures 1-5 As shown in the figure, the present application provides a photovoltaic module with windproof function, which comprises a counterweight seat 1 mounted on a base, four outer surfaces of the counterweight seat 1 are provided with photovoltaic side plates 3 which can be adjusted in angle at the same time, the bottom of each photovoltaic side plate 3 is hinged to the base, and the back of each photovoltaic side plate 3 is provided with a plurality of positioning grooves 11;

[0042] The inside of the counterweight seat 1 is provided with an adjusting unit for simultaneously rotating the photovoltaic side plates 3, the lower part of the adjusting unit is provided with a plug-in unit for positioning the back of the photovoltaic side plate 3, and the inside of the counterweight seat 1 is provided with a power switching unit which can be lifted;

[0043] The adjusting unit comprises four threaded rods one 10 which rotate at the same time, the outer surface of each threaded rod one 10 is threadedly connected with an upper sleeve seat 9, the upper end of the upper sleeve seat 9 is hinged with a transmission rod 8, and the end of each transmission rod 8 away from the upper sleeve seat 9 is hinged to the back of the corresponding photovoltaic side plate 3;

[0044] The plug-in unit comprises four threaded rods two 16 which rotate at the same time, the outer surface of the end of each threaded rod two 16 away from the inside of the counterweight seat 1 is threadedly connected with a lower sleeve seat 15, and the lower sleeve seat 15 is slidingly arranged with a slide rod outside the counterweight seat 1;

[0045] The upper surface of each lower sleeve seat 15 is hinged with a plug-in rod, a torsional spring is arranged between the plug-in rod and the lower sleeve seat 15 for providing a rebound force, the outer side of the plug-in rod is provided with a pushing part 13 fixedly connected with the lower sleeve seat 15, and a synchronous electric cylinder for pushing the plug-in rod is mounted on the pushing part 13, and the torsional spring is used for providing a rebound force for the deflection reset of the positioning rod 12;

[0046] When the power switching unit is lifted, it is connected with the adjusting unit to simultaneously adjust the angle of the plurality of photovoltaic side plates 3.

[0047] When the power switching unit is connected with the plug-in unit when it is lowered, the plug-in angle of the plug-in rod is changed so that the plug-in rod after the change of the plug-in angle enters into the corresponding positioning groove 11;

[0048] In use, the photovoltaic assembly takes the counterweight base 1 as a bearing main body, and the photovoltaic side plates 3 are installed in four directions outside the counterweight base 1, the bottom of the photovoltaic side plate 3 is hinged with the base so that the photovoltaic side plate 3 can form a surrounding arrangement;

[0049] When external wind force acts from different directions, the photovoltaic side plates 3 simultaneously realize the synchronous adjustment of the angle through the adjusting unit; that is, the power switching unit is in the rising state and is engaged with the adjusting unit at this time, the four threaded rods one 10 in the adjusting unit simultaneously rotate under the driving, the threaded rods one 10 drive the upper sleeve seat 9 which is threadedly connected with the outer surface of the threaded rods one 10 to move in the axial direction; the axial movement of the upper sleeve seat 9 pulls the corresponding transmission rod 8, and then the pulling force is transmitted to the back of the photovoltaic side plate 3, so as to drive the four photovoltaic side plates 3 to synchronously rotate around the hinge point of the bottom of the photovoltaic side plate 3 with the base, realize the simultaneous adjustment of the overall angle of the photovoltaic side plates 3, and ensure the consistency of the light utilization;

[0050] Among them, the photovoltaic side plate 3 maintains a large inclination angle, ensures the front surface to face the sunlight, and improves the light utilization rate; at this time, the wind pressure is small, and the assembly can remain stable; when the photovoltaic side plate 3 moderately reduces the inclination angle, the windward area is reduced, the certain light utilization is ensured, and the wind load concentration is reduced, thereby avoiding the shaking of the assembly;

[0051] Then, the power switching unit is connected with the plug-in unit when it is lowered, so that the four threaded rods two 16 simultaneously rotate, at this time, the lower sleeve seat 15 moves in the axial direction along the slide rod direction, in this process, the plug-in rod is pushed by the synchronous electric cylinder on the pushing part 13, so that the plug-in rod deflects around the hinge point with the lower sleeve seat 15, the plug-in angle of the plug-in rod is changed, and reliable locking is completed under the cooperation of the plug-in rod and the positioning groove 11, thereby effectively preventing the wind from causing concentrated impact on the photovoltaic side plate 3 from any direction, and improving the overall wind resistance stability;

[0052] After the photovoltaic side plate 3 completes the angle adjustment and is locked by the plug-in rod inserted into the positioning groove 11, a stable surrounding multi-direction wind resistance structure is formed, when external wind force acts from different directions, the photovoltaic side plate 3 can maintain a stable angle, avoid shaking, deviation or falling due to wind pressure concentration, and the self-weight of the counterweight base 1 further enhances the overall stability, thereby effectively resisting wind impact, preventing wind force from different directions, and realizing omnidirectional wind resistance protection.

[0053] Referring to Figure 3 As shown in the figure, the plug-in rod includes a long positioning rod 12, and the end of the positioning rod 12 is connected with a touch part 14 which is in contact with the pushing end of the synchronous electric cylinder.

[0054] When the contact portion 14 of the positioning rod 12 is in contact with the pushing end of the synchronous cylinder, the positioning rod 12 rotates around the hinge point;

[0055] During the insertion action, when the lower sleeve 15 moves to the predetermined position along the sliding rod, the synchronous cylinder on the lower sleeve 15 is started, the pushing end extends outward and is in contact with the contact portion 14 at the end of the positioning rod 12;

[0056] Under the action of the pushing force, the contact portion 14 transmits the external force to the positioning rod 12, so that the positioning rod 12 rotates around the hinge point with the lower sleeve 15, thereby changing the insertion angle of the positioning rod 12;

[0057] During the rotation, the positioning rod 12 has a rebounding characteristic under the constraint of the torsional spring. When the synchronous cylinder is retracted and the external force is removed, the positioning rod 12 can be returned to the original position under the action of the torsional spring. In this way, the positioning rod 12 can be reliably inserted into the positioning groove 11 on the back of the photovoltaic side plate 3 when needed, and automatically restored to the initial position when not needed, avoiding jamming and achieving accurate control of the angle of the positioning rod 12, thereby ensuring the stability of the insertion action.

[0065] When the fixed support 22 is lowered along the vertical guide rail 23, the lower transfer bevel gear 21 meshes with the lower bevel gear 20 in the plug-in unit, the drive gear continues to drive the transmission gear 24 to rotate, driving the lower transfer bevel gear 21, so that the lower bevel gear 20 rotates, and in turn drives the threaded rod two 16 to rotate, so that the lower sleeve 15 moves axially.

[0066] At this time, the synchronous electric cylinder pushes the plug-in rod to change the angle, and the positioning rod 12 is guided into the positioning groove 11 on the back of the photovoltaic side plate 3 under the constraint of the torsional spring, and the locking is completed; through the lifting of the vertical guide rail 23 and the fixed support 22, the same set of power system is freely switched between the adjustment mode and the locking mode, and through the transmission of the transfer bevel gear 21, the compact and integrated design is realized.
