Description

Technical Field

[0001] The present invention relates to the technical field of photovoltaic power generation applications, and particularly to a photovoltaic carport. Background Art

[0002] Photovoltaic power generation is a new type of power generation system that uses the photovoltaic effect of solar cell semiconductor materials to directly convert solar radiation energy into electrical energy. It converts sunlight into direct current through photovoltaic cells and then into alternating current through an inverter for use by households, enterprises, or the power grid. Photovoltaic power generation has the advantages of being clean, renewable, and environmentally friendly, is friendly to the environment, and has broad application prospects.

[0003] A photovoltaic carport is a building facility that combines photovoltaic power generation and parking functions. By installing solar panels on the top of the carport, it converts solar energy into electrical energy, realizing both the sunshade and rain protection functions of a traditional carport and having the ability to generate electricity. At the same time, the photovoltaic carport also has the characteristics of energy conservation and environmental protection, can reduce dependence on traditional energy, reduce carbon emissions, and promote sustainable development.

[0004] The design structure of traditional photovoltaic carports is not conducive to cleaning the photovoltaic panels, mainly reflected in the difficulties, low efficiency, high costs of cleaning, and possible damage to the photovoltaic panels. Since photovoltaic carports are often located at high positions, with a large number of photovoltaic panels distributed widely, manual cleaning not only requires scaffolding or aerial work equipment, is complex to operate and has safety hazards, but also takes a long time and effort in the cleaning process, making it difficult to meet the high-frequency cleaning requirements of photovoltaic power stations. If the photovoltaic panels are not cleaned for a long time, dirt on the surface of the photovoltaic panels, such as dust, bird droppings, and leaves, will block light, reduce the solar irradiance power, thereby reducing the power generation efficiency of the photovoltaic panels and even affecting their service life. Therefore, a photovoltaic carport is proposed. Summary of the Invention

[0036] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0037] Embodiment 1

[0038] As Figures 1 - 12As shown in the figure, a photovoltaic carport proposed by the present invention includes symmetrically arranged main supports 1. At the top of each of the two main supports 1, a cross brace 3 is fixedly connected. On one side of the two cross braces 3 away from the main supports 1, a plurality of purlin brackets 4 are fixedly connected. A photovoltaic panel 2 is fixedly connected among the plurality of purlin brackets 4.

[0039] A cleaning and protection component is arranged on the photovoltaic panel 2. The cleaning and protection component is used for cleaning the surface of the photovoltaic panel 2 and protecting it in bad weather. The cleaning component includes a protective cloth 63 installed at the bottom of the photovoltaic panel 2, a water spraying frame 618 and a water absorbing and cleaning strip 616 installed at the top of the photovoltaic panel 2, and a cleaning roller 617 rotatably arranged at the top of the photovoltaic panel 2.

[0040] A driving component is jointly arranged on the two main supports 1. The driving component is used for driving the cleaning and protection component. The driving component includes a motor 5 installed on the side of one of the main supports 1, a cable reel 56 installed at the output end of the motor 5, and a steel rope 52 fixedly connected to the cable reel 56.

[0041] This photovoltaic carport is mainly composed of symmetrically arranged main supports 1, cross braces 3, purlin brackets 4 and photovoltaic panels 2. The main support 1 serves as a support structure. The cross brace 3 connects the tops of the two main supports. The purlin bracket 4 is fixed on the cross brace and is used to support the photovoltaic panel 2. The photovoltaic panel 2 is fixed among a plurality of purlin brackets 3 to form the top of the carport. This design mainly drives the cleaning and protection component to clean on the photovoltaic panel 2 through the arranged driving component, and at the same time covers the photovoltaic panel 2 with the arranged protective cloth 63.

[0042] The driving component further includes a driving shaft 510 fixedly connected to the output end of the motor 5. The driving shaft 510 is fixedly connected to the cable reel 56. A cable reel fixing plate 59 is fixedly connected to one side of the main support 1 close to the cable reel 56. The cable reel fixing plate 59 is rotatably connected to the cable reel 56.

[0043] One end of the driving shaft 510 close to the motor 5 is fixedly connected with a first driving flywheel 514 and a second driving flywheel 515. A first belt 511 is sleeved and connected on the outside of the first driving flywheel 514. A second belt 513 is sleeved and connected on the outside of the second driving flywheel 515.

[0044] A transmission shaft 54 is rotatably connected between the two main supports 1. A first driven flywheel 55 is symmetrically fixedly connected to the outside of the transmission shaft 54. The first driven flywheel 55 is sleeved and connected with the first belt 511.

[0045] There are two pairs of cable reels 56 provided, which are respectively installed on the side of the main support 1. One of the cable reels 56 is directly driven by the motor 5, and the other is driven through the provided transmission shaft 54. By starting the motor 5, the motor 5 drives the cable reel 56 to rotate through the drive shaft 510. At the same time, the drive shaft 510 drives the first driving flywheel 514 to rotate self-driven, drives the provided first belt 511 to drive the first driven flywheel 55 to rotate, and the first driven flywheel 55 drives the transmission shaft 54 to rotate self-driven, thereby driving the cable reel 56 on the other side to rotate to realize the winding and unwinding of the steel rope 52.

[0046] The inner side of the cable reel fixing plate 59 is rotationally connected with a reciprocating lead screw 57. The reciprocating lead screw 57 is in threaded connection with the wire arranging threaded ring 58. A guide post 516 is slidably arranged inside the wire arranging threaded ring 58. The guide post 516 is fixedly connected to the cable reel fixing plate 59. The wire arranging threaded ring 58 and the steel rope 52 slide relative to each other.

[0047] The reciprocating lead screw 57 extends to the outside of the cable reel fixing plate 59 and is fixedly connected to a second driven flywheel 512 at one end close to the motor 5. The second driven flywheel 512 and the second belt 513 are sleeved and connected.

[0048] During the process of the cable reel 56 rotating to realize the winding and unwinding of the steel rope 52, the drive shaft 510 drives the second driving flywheel 515 to drive the second belt 513 to move in a circular motion. The second belt 513 drives the second driven flywheel 512 to drive the reciprocating lead screw 57 to rotate. The wire arranging threaded ring 58 moves repeatedly along the reciprocating lead screw 57 under the limiting action of the guide post 516, controls the smooth winding and unwinding of the steel rope 52, and at the same time ensures the orderly winding and unwinding of the steel rope 52 on the cable reel 56.

[0049] In this embodiment, the motor 5 drives the cable reel 56 to rotate through the drive shaft 510. At the same time, the drive shaft 510 transmits power through the first belt 511 to drive the transmission shaft 54 to rotate self-driven, drives the cable reel 56 on the other side to rotate to realize the winding and unwinding of the steel rope 52. The drive shaft 510 transmits power through the second belt 513 to drive the reciprocating lead screw 57 to rotate. The wire arranging threaded ring 58 moves back and forth on the reciprocating lead screw 57, controls the smooth winding and unwinding of the steel rope 52, and ensures the stability of the cleaning and protection component during operation.

[0050] Embodiment Two

[0051] As Figures 1 - 12 shown, based on Embodiment One, the cleaning and protection component further includes guide rails 64 symmetrically fixedly connected to the top of the photovoltaic panel 2. Guide plates 67 are symmetrically fixedly connected to the inner sides of the guide rails 64. An arc-shaped protective cover 61 is slidably arranged between the two guide plates 67. A rotating rod 614 is rotatably arranged inside the arc-shaped protective cover 61. The rotating rod 614 is fixedly connected to the cleaning roller 617.

[0052] The water spraying frame 618 and the water absorption and cleaning strip 616 are fixedly connected to the arc-shaped protective cover 61 together. On the side of the arc-shaped protective cover 61 close to the motor 5, cable pulling posts 53 are symmetrically and fixedly connected. The cable pulling posts 53 are fixedly connected to the steel cable 52. Pulley 51 are symmetrically and fixedly connected to the top and bottom of the photovoltaic panel 2 respectively. The two pulleys 51 slide relative to the steel cable 52 together;

[0053] The driving component drives the cleaning and protection component to slide on the photovoltaic panel 2. The cleaning part in the cleaning and protection component mainly uses the set water spraying frame 618 to spray water on the photovoltaic panel 2 while it is moving, and the cleaning roller 617 rotates to clean the photovoltaic panel 2. The water absorption and cleaning strip 616 follows closely behind to absorb excess water and dirt. The arc-shaped protective cover 61 plays a role in preventing splashing during the movement, preventing the water spraying frame 618 from contaminating the cleaned area.

[0054] A rack 69 is fixedly connected to the inner side of the guide rail 64. A gear 68 is fixedly connected to one end of the rotating rod 614 close to the rack 69. The gear 68 meshes with the rotating rod 614. A guide groove 610 is opened on the inner side of the guide rail 64. A slider 612 is slidably arranged on the inner side of the guide groove 610. An elastic member 613 is fixedly connected to the side of the slider 612 close to the rotating rod 614. One end of the elastic member 613 far from the slider 612 is fixedly connected to a collar 615. The collar 615 is rotatably connected to the rotating rod 614;

[0055] During the process of the motor 5 driving the steel cable 52 to pull the arc-shaped protective cover 61 to move between the guide plates 67, the meshing of the gear 68 and the rack 69 ensures that the rotating rod 614 drives the cleaning roller 617 to rotate for cleaning. At the same time, the set elastic member 613 is in a compressed state, always keeping the collar 615 pressing against the close meshing of the gear 68 and the rack 69.

[0056] A protective cloth housing 62 is fixedly connected to the bottom of the photovoltaic panel 2. A fixed post 65 is fixedly connected to the inner side of the protective cloth housing 62. A disc spring 66 is fixedly connected to the outer side of the fixed post 65. The disc spring 66 is fixedly connected to the protective cloth 63. The protective cloth 63 slides relative to the notch of the protective cloth housing 62. The other end of the protective cloth 63 is fixedly connected to the arc-shaped protective cover 61. A guide roller 619 is fixedly connected to the side of the photovoltaic panel 2 close to the arc-shaped protective cover 61. The guide roller 619 is in mutual contact with the protective cloth 63;

[0057] During the cleaning process, the motor 5 continues to drive the arc-shaped protective cover 61 to slide from the front section to the rear section of the photovoltaic panel 2. The movement of the arc-shaped protective cover 61 drives one end of the protective cloth 63 to unfold and cover the photovoltaic panel 2. At this time, the disc spring 66 contracts and is stressed, and the guide roller 619 fits with the protective cloth 63 to ensure that the protective cloth 63 remains flat during the unfolding and retracting processes. Subsequently, when the weather improves, the motor 5 reverses, and the disc spring 66 releases its elastic force to drive the arc-shaped protective cover 61 to return to its initial position along the guide rail 64. The return of the arc-shaped protective cover 61 drives the cleaning roller 617 to roll again to ensure that there is no residual dirt on the surface of the photovoltaic panel 2. At the same time, the protective cloth 63 gradually rolls up under the action of the disc spring 66 and retracts into the protective cloth housing 62.

[0058] In this embodiment, the motor 5 drives the steel cable 52 to pull the arc-shaped protective cover 61 to slide from the front section to the rear section of the photovoltaic panel 2. During this process, the water spraying frame 618, the cleaning roller 617, and the water-absorbing cleaning strip 616 cooperate with each other to clean the photovoltaic panel. The movement of the arc-shaped protective cover 61 drives one end of the protective cloth 63 to unfold and cover the photovoltaic panel 2. Subsequently, when the weather improves, the motor 5 reverses, and the disc spring 66 releases its elastic force to drive the arc-shaped protective cover 61 to return to its initial position along the guide rail 64. The protective cloth 63 retracts into the protective cloth housing 62 under the action of the disc spring 66.

[0059] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
