Description

Technical Field

[0001] The present invention relates to the technical field of photovoltaic power generation auxiliary devices, and in particular to a distributed photovoltaic power generation mechanism. Background Art

[0002] Photovoltaic: It is the abbreviation of solar photovoltaic power generation system. It 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 has two modes of independent operation and grid-connected operation. At the same time, solar photovoltaic power generation systems are classified into two types: centralized, such as large-scale northwest ground photovoltaic power generation systems; and distributed (with >6MW as the boundary), such as photovoltaic power generation systems on the roofs of industrial and commercial factories and photovoltaic power generation systems on the roofs of residential buildings. Photovoltaic is defined as the direct conversion of ray energy. In practical applications, it usually refers to the conversion of solar energy into electrical energy, that is, solar photovoltaic. It is mainly achieved by using solar panels made of semiconductor materials such as silicon to generate direct current using light, such as solar cells that can be seen everywhere in our daily lives.

[0003] my country has a vast territory, and the weather conditions vary greatly from place to place. For some areas where winds are common, existing distributed photovoltaic power generation mechanisms are very susceptible to strong winds, especially photovoltaic panels, which have a large area and are subject to greater force when blown by the wind, which may damage the brackets supporting the photovoltaic panels, causing them to deform and eventually lead to failure to work properly. Summary of the invention

[0004] In order to solve the above technical problems, the present invention provides a distributed photovoltaic power generation mechanism with a simple and reliable structure. When there is a strong wind, the photovoltaic panels can be automatically stored in a protective box to avoid damage and increase the service life of the device.

[0005] A distributed photovoltaic power generation mechanism of the present invention comprises a protection box and a photovoltaic panel, wherein the photovoltaic panel is inside the protection box, the protection box is hollow inside and has an opening at the top, and cover plates are rotatably connected to the front and rear sides of the opening;

[0006] A power mechanism 1 is arranged inside the protection box, and the power mechanism 1 is used to drive the photovoltaic panel to lift and rotate;

[0007] A second power mechanism is also provided on both sides of the interior of the protection box, and the second power mechanism is used to drive the cover plate to rotate.

[0008] Furthermore, the power mechanism 1 includes two fixing plates fixedly connected to the inner wall of the protection box, and both fixing plates are provided with through hole 1 and through hole 2;

[0009] The through hole 1 is vertical, the through hole 2 is arc-shaped, the through hole 2 is connected to the through hole 1, and the center of the through hole 2 is concentric with the center of the top of the through hole 1;

[0010] A connecting plate is fixed on both sides of one end of the photovoltaic panel, and a fixing shaft 1 and a fixing shaft 2 are fixed on the connecting plate. When the photovoltaic panel is inside the protective box, the fixing shaft 1 and the fixing shaft 2 both pass through the through hole 1, and the fixing shaft 1 is above the through hole 2;

[0011] The power mechanism 1 also includes a power mechanism 3 for driving the fixed shaft 2 to move along part of the through hole 1 and the through hole 2.

[0012] Furthermore, the power mechanism three includes a rotating shaft rotatably connected to the protection box, both ends of the rotating shaft are fixedly connected to one end of the driving rod one, and the other end of the driving rod one is rotatably connected to one end of the driving rod two;

[0013] The other end of the second driving rod is rotatably connected to the second fixed shaft.

[0014] Furthermore, the power mechanism 2 comprises a track fixedly connected to the inner wall of the protection box, the track is slidably connected to a slider, and the fixed shaft 1 is rotatably connected to the slider;

[0015] The slider is rotatably connected to one end of the push rod, and the other end of the push rod is rotatably connected to the bottom of the cover plate.

[0016] Furthermore, the power mechanism 1 also includes a power mechanism 4 for driving the rotating shaft to rotate;

[0017] The power mechanism 4 includes fixed rods fixed at both ends of the rotating shaft, and the fixed rods are provided with long holes;

[0018] The power mechanism 4 also includes a moving mechanism fixed on both sides of the protection box, the output end of the moving mechanism is a translation plate, the translation plate is fixedly connected to the driving shaft, and the driving shaft passes through the long hole.

[0019] Furthermore, the translation mechanism includes a screw rod rotatably connected to the protection box, the screw rod is threadedly connected to the translation plate, and the translation plate is slidably connected to the protection box;

[0020] One end of the screw rod is fixedly connected with a motor for driving the screw rod to rotate.

[0021] Furthermore, the fixed shaft 1 and the fixed shaft 2 are both fixedly connected with rollers, and the rollers are clamped on the fixed plate.

[0022] Furthermore, a bearing is fixed to the driving shaft, and an outer ring of the bearing contacts the inner wall of the elongated hole.

[0023] Compared with the prior art, the beneficial effects of the present invention are as follows: when the photovoltaic panel is inside the protection box, the fixed shaft one and the fixed shaft two both pass through the through hole one, and the fixed shaft one is above the through hole two. When the photovoltaic panel needs to be used, the rotating shaft is operated to rotate the rotating shaft clockwise. Since the driving rod one is fixedly connected to the rotating shaft, the driving rod one is driven to rotate clockwise. Since the other end of the driving rod one is rotationally connected to one end of the driving rod two, the other end of the driving rod two is rotationally connected to the fixed shaft two, and the fixed shaft one, the fixed shaft two and the connecting plate are a whole, when the driving rod one rotates counterclockwise, the fixed shaft one and the fixed shaft two can be pushed to move upward along the through hole one at the same time. In this process, the fixed shaft one drives the sliding block to move upward along the track. Since the sliding block is rotationally connected to one end of the push rod, and the other end of the push rod is rotationally connected to the bottom of the cover plate, the sliding block moving upward can rotate the cover plate, and when the fixed shaft one stops moving upward, the cover plate also stops rotating.

[0024] When fixed shaft one moves to the top of through hole one, fixed shaft two moves to the connection between through hole one and through hole two. Since fixed shaft one cannot move upward further at this time and the rotating shaft is at the lower left of through hole one, an oblique thrust is generated on fixed shaft two, causing fixed shaft two to move along through hole two. When the position of fixed shaft one remains unchanged, fixed shaft one, fixed shaft two, connecting plate and photovoltaic panel rotate around the axis of fixed shaft one until the appropriate angle is reached, and then the rotating shaft can be stopped.

DETAILED DESCRIPTION

[0032] The specific implementation of the present invention is further described in detail below in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0033] like Figures 1 to 6 As shown, a distributed photovoltaic power generation mechanism of the present invention comprises a protection box 1 and a photovoltaic panel 2, wherein the photovoltaic panel 2 is inside the protection box 1, the protection box 1 is hollow inside and has an opening at the top, and the front and rear sides of the opening are rotatably connected with a cover plate 3;

[0034] A power mechanism 1 is provided inside the protection box 1, and the power mechanism 1 is used to drive the photovoltaic panel 2 to lift and rotate;

[0035] A power mechanism 2 is also provided on both sides of the protection box 1, and the power mechanism 2 is used to drive the cover plate 3 to rotate;

[0036] In this embodiment, if Figure 1 As shown, in bad weather, the power mechanism 1 and the power mechanism 2 are operated to make the photovoltaic panel 2 enter the protection box 1 and close the cover 3, so as to protect the photovoltaic panel 2. In normal weather, the power mechanism 1 and the power mechanism 2 are operated to open the cover 3, and the photovoltaic panel 2 is tilted to play a role in normal power generation. Through the cooperation of the power mechanism 1 and the power mechanism 2, the opening and closing of the cover 3 and the tilting of the photovoltaic panel 2 can be achieved by one power, and the use cost is lower.

[0037] Furthermore, the power mechanism 1 includes two fixing plates 4 fixedly connected to the inner wall of the protection box 1, and the two fixing plates 4 are both provided with a through hole 1 5 and a through hole 2 6;

[0038] The through hole 1 5 is vertical, the through hole 2 6 is arc-shaped, the through hole 2 6 is connected with the through hole 1 5, and the center of the through hole 2 6 is concentric with the center of the top of the through hole 1 5;

[0039] A connecting plate 7 is fixed on both sides of one end of the photovoltaic panel 2, and a fixing shaft 1 8 and a fixing shaft 2 9 are fixed on the connecting plate 7. When the photovoltaic panel 2 is inside the protection box 1, the fixing shaft 1 8 and the fixing shaft 2 9 both pass through the through hole 1 5, and the fixing shaft 1 8 is above the through hole 2 6;

[0040] The power mechanism 1 also includes a power mechanism 3 for driving the fixed shaft 2 9 to move along part of the through hole 1 5 and the through hole 2 6;

[0041] Furthermore, the power mechanism 3 includes a rotating shaft 10 rotatably connected to the protection box 1, and both ends of the rotating shaft 10 are fixedly connected to one end of a driving rod 11, and the other end of the driving rod 11 is rotatably connected to one end of a driving rod 2 12, such as Figure 5 and Figure 6 As shown, the driving rod 11 and the driving rod 2 12 form a V shape;

[0042] The other end of the driving rod 12 is rotatably connected to the fixed shaft 9;

[0043] In this embodiment, if Figure 3 As shown, when the photovoltaic panel 2 is inside the protective box 1, the fixed shaft 1 8 and the fixed shaft 2 9 both pass through the through hole 1 5, and the fixed shaft 1 8 is above the through hole 2 6. When the photovoltaic panel 2 needs to be used, the rotating shaft 10 is operated to rotate the rotating shaft 10 clockwise. Since the driving rod 1 11 is fixedly connected to the rotating shaft 10, the driving rod 1 11 is driven to rotate clockwise. Since the other end of the driving rod 1 11 is rotationally connected to one end of the driving rod 2 12, and the other end of the driving rod 2 12 is rotationally connected to the fixed shaft 2 9, and the fixed shaft 1 8, the fixed shaft 2 9 and the connecting plate 7 are a whole, the driving rod 11 is rotated counterclockwise. When the fixed shaft 18 is moved to the top of the through hole 15, the fixed shaft 29 moves to the connection between the through hole 15 and the through hole 26. Since the fixed shaft 8 cannot move upward at this time and the rotating shaft 10 is at the lower left of the through hole 15, an oblique thrust is generated on the fixed shaft 29, so that the fixed shaft 29 moves along the through hole 26. When the position of the fixed shaft 8 remains unchanged, the fixed shaft 18, the fixed shaft 29, the connecting plate 7 and the photovoltaic panel 2 rotate around the axis of the fixed shaft 8 until the appropriate angle is reached, and the rotating shaft 10 is stopped.

[0044] Furthermore, the power mechanism 2 includes a track 13 fixedly connected to the inner wall of the protection box 1, the track 13 is slidably connected to a slider 14, and the fixed shaft 1 8 is rotatably connected to the slider 14;

[0045] The slider 14 is rotatably connected to one end of the push rod 15, and the other end of the push rod 15 is rotatably connected to the bottom of the cover plate 3;

[0046] In this embodiment, it can be seen from the above process that the photovoltaic panel 2 will move vertically upward before tilting. During this process, the fixed shaft 8 drives the slide to move upward along the track 13. Since the slider 14 is rotatably connected to one end of the push rod 15, and the other end of the push rod 15 is rotatably connected to the bottom of the cover 3, the upward moving slider 14 can rotate the cover 3, and when the fixed shaft 8 stops moving upward, the cover 3 also stops rotating.

[0047] Furthermore, the power mechanism 1 also includes a power mechanism 4 for driving the rotating shaft 10 to rotate;

[0048] The power mechanism 4 includes fixed rods 16 fixed to both ends of the rotating shaft 10, and the fixed rods 16 are provided with long holes;

[0049] The power mechanism 4 also includes a moving mechanism fixed on both sides of the protection box 1, the output end of the moving mechanism is a translation plate 17, the translation plate 17 is fixedly connected to the driving shaft 18, and the driving shaft 18 passes through the elongated hole;

[0050] Furthermore, the translation mechanism includes a screw rod 19 rotatably connected to the protection box 1, the screw rod 19 is threadedly connected to the translation plate 17, and the translation plate 17 is slidably connected to the protection box 1;

[0051] One end of the screw rod 19 is fixedly connected to a motor 20 for driving the screw rod 19 to rotate;

[0052] In this embodiment, two motors 20 are operated simultaneously to rotate the screw 19. When the screw 19 rotates, the translation plate 17 and the driving shaft 18 are translated. Since the driving shaft 18 passes through the long hole, it can push the fixed rod 16 and the rotating shaft 10 to rotate, thereby causing the cover plate 3 and the photovoltaic panel 2 to move.

[0053] Furthermore, the fixed shaft 1 8 and the fixed shaft 2 9 are both fixedly connected with rollers 21, and the rollers 21 are clamped on the fixed plate 4;

[0054] In this embodiment, the roller 21 is provided to limit the front-rear positions of the fixed shaft 1 8 and the fixed shaft 2 9 to prevent movement.

[0055] Furthermore, the driving shaft 18 is fixed with a bearing 22, and the outer ring of the bearing 22 is in contact with the inner wall of the elongated hole;

[0056] In this embodiment, the bearing 22 is provided so that the driving shaft 18 does not come into direct contact with the fixing rod 16 , thereby reducing the wear on the driving shaft 18 .

[0057] A distributed photovoltaic generator 20 of the present invention, when working, Figure 3As shown, when the photovoltaic panel 2 is inside the protective box 1, the fixed shaft 1 8 and the fixed shaft 2 9 both pass through the through hole 1 5, and the fixed shaft 1 8 is above the through hole 2 6. When the photovoltaic panel 2 needs to be used, the rotating shaft 10 is operated to rotate the rotating shaft 10 clockwise. Since the driving rod 1 11 is fixedly connected to the rotating shaft 10, the driving rod 1 11 is driven to rotate clockwise. Since the other end of the driving rod 1 11 is rotatably connected to one end of the driving rod 2 12, the other end of the driving rod 2 12 is rotatably connected to the fixed shaft 2 9, and the fixed shaft 8 , the fixed shaft 29 and the connecting plate 7 are an integral whole, so when the driving rod 11 rotates counterclockwise, it can push the fixed shaft 18 and the fixed shaft 29 to move upward along the through hole 15 at the same time. In this process, the fixed shaft 18 drives the slide to move upward along the track 13. Since the slider 14 is rotatably connected to one end of the push rod 15, and the other end of the push rod 15 is rotatably connected to the bottom of the cover plate 3, the upward moving slider 14 can rotate the cover plate 3, and when the fixed shaft 8 stops moving upward, the cover plate 3 also stops rotating;

[0058] When the fixed shaft 8 moves to the top of the through hole 15, the fixed shaft 29 moves to the connection between the through hole 15 and the through hole 26. Since the fixed shaft 8 cannot move upward at this time and the rotating shaft 10 is at the lower left of the through hole 15, an oblique thrust is generated on the fixed shaft 29, causing the fixed shaft 29 to move along the through hole 26. When the position of the fixed shaft 8 remains unchanged, the fixed shaft 18, the fixed shaft 29, the connecting plate 7 and the photovoltaic panel 2 rotate around the axis of the fixed shaft 8 until the appropriate angle is reached, and then the rotating shaft 10 can be stopped.

[0059] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
