Description

Technical Field

[0001] The present invention relates to the technical field of photovoltaic power generation, and in particular to an integrated distributed photovoltaic power generation device. Background Art

[0002] Photovoltaic power generation is a technology that uses the photovoltaic effect of semiconductor interfaces to directly convert light energy into electrical energy. It is mainly composed of three parts: solar panels (modules), controllers and inverters, and the main components are composed of electronic components. After solar cells are connected in series and packaged for protection, they can form large-area solar cell modules, which are then combined with power controllers and other components to form photovoltaic power generation devices.

[0003] The integrated distributed photovoltaic power generation device in the prior art has the following problems: the photovoltaic panels that receive sunlight mostly receive sunlight directly and are affected by wind and sand for a long time, resulting in a large amount of dust on the surface of the photovoltaic panels. In the prior art, a handheld cleaner is generally used to clean the surface of the photovoltaic panels. This method is inefficient and affects the power generation efficiency of the photovoltaic panels. Summary of the invention

[0004] In order to solve the above technical problems, the present invention provides an integrated distributed photovoltaic power generation device, which has a simple structure and can automatically clean the surface of photovoltaic panels without manual processing, thereby improving convenience of use.

[0005] An integrated distributed photovoltaic power generation device of the present invention comprises a bottom plate, a brush roller and a photovoltaic panel, wherein vertical plates are fixed on both sides of the top of the bottom plate, and both sides of the photovoltaic panel are respectively fixed on the two vertical plates, and the vertical plates are provided with through holes, and the through holes are arranged along the length direction of the photovoltaic panel, and also comprises a bearing moving along the through holes, and the bearing is internally connected to a rotating shaft, and the two ends of the brush roller are respectively connected to one end of the two rotating shafts;

[0006] Also included is a driving mechanism for driving the bearing to move along the through hole;

[0007] The utility model also comprises a power mechanism for driving the brush roller to rotate.

[0008] Furthermore, the driving mechanism comprises a driving shaft 1 rotatably connected to the two vertical plates, and both ends of the driving shaft 1 are fixedly connected to driving rods, and the driving rods are provided with long holes along the length direction thereof;

[0009] The rotating shaft passes through the elongated hole.

[0010] Furthermore, the driving mechanism also includes a motor 1 fixed to an end portion of the driving shaft.

[0011] Furthermore, the power mechanism comprises a driving shaft 2 rotatably connected to the two vertical plates, both ends of the driving shaft 2 are rotatably connected to one end of the adapting arm 1, and the other end of the adapting arm 1 is rotatably connected to the transition shaft;

[0012] The transition shaft is rotatably connected to one end of the second adaptable arm, and the other end of the second adaptable arm is rotatably connected to the rotating shaft;

[0013] The transition shaft and the rotating shaft as well as the transition shaft and the second driving shaft are connected by chain transmission.

[0014] Furthermore, the power mechanism also includes a second motor fixed to one end of the second driving shaft.

[0015] Furthermore, both sides of one end of the base plate are rotatably connected with supporting legs, the other end of the base plate is rotatably connected with one end of the oil cylinder, and the other end of the oil cylinder is rotatably connected with a fixed plate.

[0016] Furthermore, both sides of the through hole are connected with L-shaped holes, and the two L-shaped holes are symmetrically arranged.

[0017] Furthermore, limiting rings are fixed at both ends of the bearing.

[0018] Compared with the prior art, the present invention has the following beneficial effects: the bottom ends of the legs and the bottom ends of the fixing plates are fixedly connected to the external supporting surface, and the angle of the photovoltaic panel can be controlled by controlling the extension and contraction of the oil cylinder piston rod, so that the photovoltaic panel can be in the best power generation state;

[0019] When the photovoltaic panel needs to be cleaned, motor one and motor two are turned on. When motor two is turned on, drive shaft two is driven to rotate. Since the transition shaft and the rotating shaft, as well as the transition shaft and drive shaft two are connected by chain transmission, motor two can drive the rotating shaft and the brush roller to rotate after it is turned on. After motor one is turned on, it drives drive shaft one and a driving rod fixedly connected thereto to rotate. The rotating shaft passes through a long hole opened along the length direction of the driving rod, and drive shaft one is located in the middle and lower part of the through hole. Therefore, the driving rod can generate thrust on the rotating shaft during the rotation process with drive shaft one as the axis, so that the rotating shaft and the bearing move along the through hole. In this process, the relative position of the rotating shaft and the driving rod changes to adapt to the position change of the rotating shaft.

[0020] In summary, when motor one and motor two are turned on at the same time, the brush roller can move along the surface of the photovoltaic panel. After cleaning, the bearing moves to the end of the L-shaped hole away from the through hole. At this time, the photovoltaic panel blocks the brush roller to prevent sunlight exposure.

[0026] 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.

[0027] like Figures 1 to 4 As shown, an integrated distributed photovoltaic power generation device of the present invention comprises a bottom plate 1, a brush roller 2 and a photovoltaic panel 3, vertical plates 4 are fixed on both sides of the top of the bottom plate 1, and both sides of the photovoltaic panel 3 are respectively fixed on the two vertical plates 4, and the vertical plates 4 are provided with through holes 5, and the through holes 5 are arranged along the length direction of the photovoltaic panel 3, and also include bearings 6 moving along the through holes 5, and the bearings 6 are internally rotatably connected to the rotating shaft 7, and the two ends of the brush roller 2 are respectively connected to one end of the two rotating shafts 7;

[0028] It also includes a driving mechanism for driving the bearing 6 to move along the through hole 5;

[0029] It also includes a power mechanism for driving the brush roller 2 to rotate;

[0030] In this embodiment, when in use, the rotating shaft 7 and the brush roller 2 are driven to rotate by a power mechanism, and the rotating brush roller 2 cleans the surface of the photovoltaic panel 3. The brush roller 2, the rotating shaft 7 and the bearing 6 can be moved along the through hole 5 by the driving mechanism. The through hole 5 is arranged along the length direction of the photovoltaic panel 3, so under the action of the driving mechanism, the brush roller 2 can move along the surface of the photovoltaic panel 3, thereby cleaning the entire surface of the photovoltaic panel 3 that receives sunlight. It is only necessary to manually sprinkle water on the surface of the photovoltaic panel 3, and then cooperate with the movement and rotation of the brush roller 2 to complete the cleaning of the surface of the photovoltaic panel 3.

[0031] Furthermore, the driving mechanism includes a driving shaft 8 rotatably connected to the two vertical plates 4, and both ends of the driving shaft 8 are fixedly connected to driving rods 9, and the driving rod 9 has a long hole 10 along its length direction;

[0032] The rotating shaft 7 passes through the elongated hole 10;

[0033] Furthermore, the driving mechanism also includes a motor 11 fixed to the end of the driving shaft 8;

[0034] In this embodiment, if Figure 1 and Figure 3 As shown, the drive shaft 8 is located in the middle and lower part of the through hole 5. After the motor 11 is turned on, it drives the drive shaft 8 and the drive rod 9 fixedly connected thereto to rotate. The rotating shaft 7 passes through the long hole 10 opened along the length direction of the driving rod 9, and the drive shaft 8 is located in the middle and lower part of the through hole 5. Therefore, during the rotation process with the drive shaft 8 as the axis, the drive rod 9 can generate thrust on the rotating shaft 7, so that the rotating shaft 7 and the bearing 6 move along the through hole 5. During this process, the relative position of the rotating shaft 7 and the drive rod 9 changes to adapt to the position change of the rotating shaft 7.

[0035] Furthermore, the power mechanism includes a second drive shaft 12 rotatably connected to the two vertical plates 4, both ends of the second drive shaft 12 are rotatably connected to one end of an adaptation arm 13, and the other end of the adaptation arm 13 is rotatably connected to a transition shaft 22;

[0036] The transition shaft 22 is rotatably connected to one end of the second adaptation arm 14, and the other end of the second adaptation arm 14 is rotatably connected to the rotating shaft 7;

[0037] The transition shaft 22 and the rotating shaft 7 as well as the transition shaft 22 and the second driving shaft 12 are connected by a chain 15;

[0038] Furthermore, the power mechanism also includes a motor 16 fixed to one end of the drive shaft 12;

[0039] In this embodiment, when the motor 2 16 is turned on, the drive shaft 2 12 is driven to rotate. Since the transition shaft 22 and the rotating shaft 7 and the transition shaft 22 and the drive shaft 2 12 are connected by the chain 15, the motor 2 16 can drive the rotating shaft 7 and the brush roller 2 to rotate after it is turned on.

[0040] During the movement of the bearing 6 along the through hole 5, the distance between the bearing 6 and the drive shaft 2 12 changes. In order to adapt to this change, the adaptation arm 13 and the adaptation arm 2 14 rotate, but the distance between the transition shaft 22 and the rotating shaft 7 and the distance between the transition shaft 22 and the drive shaft 2 12 remain unchanged, so the chain 15 can maintain a normal state of use.

[0041] Furthermore, both sides of one end of the bottom plate 1 are rotatably connected to the legs 17, the other end of the bottom plate 1 is rotatably connected to one end of the oil cylinder 18, and the other end of the oil cylinder 18 is rotatably connected to the fixing plate 19;

[0042] In this embodiment, the bottom ends of the legs 17 and the fixing plate 19 are fixedly connected to the external support surface. By controlling the extension and retraction of the piston rod of the oil cylinder 18, the angle of the photovoltaic panel 3 can be controlled, so that the photovoltaic panel 3 can be in the best power generation state.

[0043] Furthermore, both sides of the through hole 5 are connected with L-shaped holes 20, and the two L-shaped holes 20 are symmetrically arranged;

[0044] In this embodiment, the driving shaft 8 is not only located in the middle and lower part of the through hole 5, but also in the area surrounded by the through hole 5 and the two L-shaped holes 20. The rotating shaft 7 passes through the long hole 10 opened along the length direction of the driving rod 9. Therefore, the driving rod 9 can generate thrust on the rotating shaft 7 during the rotation process with the driving shaft 8 as the axis, so that the rotating shaft 7 and the bearing 6 move along the through hole 5 and the L-shaped hole 20. In this process, the relative position of the rotating shaft 7 and the driving rod 9 changes to adapt to the position change of the rotating shaft 7.

[0045] After cleaning is completed, the bearing 6 is moved to the end of the L-shaped hole 20 away from the through hole 5. At this time, the photovoltaic panel 3 shields the brush roller 2 to prevent it from being exposed to sunlight.

[0046] Furthermore, both ends of the bearing 6 are fixed with a limit ring 21;

[0047] In this embodiment, by fixing the limiting rings 21 at both ends of the bearing 6, the bearing 6 can be limited in the front-to-back direction to prevent the brush roller 2 from shifting forward and backward.

[0048] The integrated distributed photovoltaic power generation device of the present invention, when working, the bottom ends of the legs 17 and the bottom ends of the fixing plates 19 are fixedly connected to the external support surface, and the angle of the photovoltaic panel 3 can be controlled by controlling the extension and contraction of the piston rod of the oil cylinder 18, so that the photovoltaic panel 3 can be in the best power generation state;

[0049] When the photovoltaic panel 3 needs to be cleaned, the motor 11 and the motor 2 16 are turned on. When the motor 2 16 is turned on, the drive shaft 2 12 is driven to rotate. Since the transition shaft 22 and the rotating shaft 7 and the transition shaft 22 and the drive shaft 2 12 are connected by the chain 15, the motor 2 16 can drive the rotating shaft 7 and the brush roller 2 to rotate after it is turned on. After the motor 11 is turned on, it drives the drive shaft 1 8 and the drive rod 9 fixedly connected thereto to rotate. The rotating shaft 7 passes through the long strip hole 10 opened along the length direction of the drive rod 9, and the drive shaft 1 8 is located in the middle and lower part of the through hole 5. Therefore, the drive rod 9 can generate thrust on the rotating shaft 7 during the rotation process with the drive shaft 1 8 as the axis, so that the rotating shaft 7 and the bearing 6 move along the through hole 5. In this process, the relative position of the rotating shaft 7 and the drive rod 9 changes to adapt to the position change of the rotating shaft 7.

[0050] In summary, when motor 1 11 and motor 2 16 are turned on at the same time, the brush roller 2 can move along the surface of the photovoltaic panel 3. After cleaning, the bearing 6 moves to the end of the L-shaped hole 20 away from the through hole 5. At this time, the photovoltaic panel 3 covers the brush roller 2 to prevent it from being exposed to sunlight.

[0051] 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.
