Description

Technical Field

[0001] The utility model relates to the technical field of photovoltaic brackets, and more specifically, to a ditch fixing bracket. Background Art

[0002] Photovoltaics is a power generation system that uses the photovoltaic effect of photovoltaic cells to directly convert solar radiation energy into electrical energy. When installing photovoltaics, in order to ensure better use of photovoltaics, it is necessary to support the photovoltaic panels with fixed brackets. At the same time, the direction and use angle of the photovoltaic panels need to be adjusted to meet the photovoltaic panels' better lighting needs;

[0003] At present, as the excessive use of photovoltaic panels has led to a large amount of land occupation, in order to reduce the use of land, people are considering using fixed brackets to install photovoltaics in ditches, which can fundamentally solve the problem of land use difficulties;

[0004] However, most of the current photovoltaic fixed brackets are assembled by welding support rods, and therefore do not have the function of adjusting the angle of the solar panel, which is not conducive to the maximum angle of sunlight radiation and reduces the power generation efficiency of the device.

[0005] The utility model patent with patent application number CN202122162696.6 discloses a photovoltaic fixed bracket. The structure utilizes the rotation of the fixed plate to allow the card to slide in the slide rail and the slider to slide in the slide groove. The angle of the solar panel body on the chassis guide rail can be adjusted, so that the solar panel has the effect of angle adjustment.

[0006] However, this structure has the following limitations in actual use:

[0007] 1. This structure can only adjust the tilt of the photovoltaic panel, and it is difficult to rotate and adjust the direction of the photovoltaic panel according to the situation, so the scope of use is limited;

[0008] 2. If the bracket is in a ditch or river, rainy weather may easily cause the water level in the ditch to rise, and the bracket is difficult to adjust the height of the photovoltaic panel, resulting in the photovoltaic panel being affected by the rising water level;

[0009] 3. When it rains or snows, a large amount of snow will accumulate on the surface of the photovoltaic panels, which is difficult to remove. This not only affects the use of the photovoltaic panels, but also increases the workload of the staff.

[0036] The motor 27 can drive the screw 24 inside one of the mounting grooves 25 to rotate, so that the threaded block 32 drives one of the threaded rods 28 to move. Under the action of the adjusting plate 29, the slider 33 slides and guides on the outside of the slide rod 26, and then the movement of the adjusting plate 29 can drive the cleaning plate 30 to fit the surface of the photovoltaic panel 5 for cleaning, thereby avoiding dust or snow on the surface of the photovoltaic panel 5 from affecting the use of the photovoltaic panel 5.

[0037] In a specific embodiment, as shown in the attached Figure 1 ,2 As shown, buoys 16 are provided on both sides of the support plate 6 , a connecting piece 17 is provided between the buoys 16 and the support plate 6 , and the buoys 16 are connected to the support plate 6 through the connecting piece 17 , and bolts 18 are provided between the connecting piece 17 and the support plate 6 .

[0038] In this structure, when the bracket is installed inside the ditch, in order to prevent excessive rain from affecting the photovoltaic panel 5, when there is too much water inside the ditch, the float 16 will generate buoyancy, and then the support plate 6 will drive the support column 2 to slide upward inside the column 1, and the photovoltaic panel 5 can be adjusted in height according to the water level inside the ditch;

[0039] The buoy 16 is connected to the support plate 6 via a connector 17 , and the connector 17 can be connected to the support plate 6 via bolts 18 , so that the operator only needs to remove the bolts 18 to remove and replace the buoy 16 and the support plate 6 .

[0040] In a specific embodiment, as shown in the attached Figure 1 , 4 As shown, rotating rods 19 are provided at both ends of the mounting plate 4, and the mounting plate 4 is rotatably connected inside the Y-shaped frame 3 through the rotating rods 19, and the rotating rods 19 at both ends of the mounting plate 4 extend to one side of the outer wall of the Y-shaped frame 3 respectively, and a connecting disk 20 is provided at one end of the two rotating rods 19. The outer surface of the connecting disk 20 is circular and has a plurality of screw holes 21. A support block 22 is provided at the bottom of the connecting disk 20 on the outer wall of the Y-shaped frame 3, and a positioning screw 23 is installed on the internal thread of the support block 22, and the positioning screw 23 is threadedly connected to the screw hole 21.

[0041] In this structure, the tilt angle adjustment of the photovoltaic panel 5 can be achieved. Specifically, the mounting plate 4 can be rotated inside the Y-shaped frame 3 through two rotating rods 19, so that the installation angle of the photovoltaic panel 5 can be adjusted. During the rotation of the rotating rod 19, the connecting disk 20 will be rotated. The operator can rotate the positioning screw 23 at the support block 22 and rotate the positioning screw 23 to the inside of the screw hole 21 at the connecting disk 20, so as to limit and fix the connecting disk 20 to prevent the adjusted mounting plate 4 from tilting and rotating again.

[0042] Working principle of this utility model:

[0043] When the above structure is used, first, the column 1 can be installed inside the ditch, and the column 1 and the support column 2 both play the effect of supporting the Y-shaped frame 3, and the mounting plate 4 equipped with the photovoltaic panel 5 is installed inside the Y-shaped frame 3. The mounting plate 4 can be rotated inside the Y-shaped frame 3 through two rotating rods 19 to adjust the inclination angle of the photovoltaic panel 5. During the rotation of the rotating rod 19, the connecting plate 20 will be rotated. The operator rotates the positioning screw 23 at the support block 22 and rotates the positioning screw 23 to the inside of the screw hole 21 at the connecting plate 20, so as to limit and fix the connecting plate 20, so as to prevent the mounting plate 4 from tilting and rotating again after adjustment, and complete the inclination adjustment of the photovoltaic panel 5;

[0044] Then, the support plate 6 is fixed to the top of the support column 2, and the turntable 7 is fixed to the bottom end of the Y-shaped frame 3. At the same time, the support plate 6 and the turntable 7 can be rotated by the shaft rod 8. The rotation of the turntable 7 can realize the rotation adjustment of the Y-shaped frame 3, thereby achieving the rotation adjustment of the direction of the photovoltaic panel 5, and by pressing the pressing plate 15 downward, the pressing plate 15 slides inside the rectangular groove 14 opened in the fixed frame 9, and drives the extrusion plate 12 to slide downward inside the fixed frame 9, and squeezes the compression spring 13. At the same time, the extrusion plate 12 can drive the extension rod 10 and the positioning column 11 to extend downward during the downward sliding process. When the pressing plate 15 is released, the compression spring 13 is reset after being squeezed, so that the positioning column 11 can be driven to be stuck in the positioning hole opened at the bottom of the turntable 7. The positioning column 11 is used to limit the positioning hole, thereby realizing the limitation of the turntable 7, avoiding the phenomenon that the turntable 7 after adjustment rotates for no reason, thereby realizing the rotation adjustment of the direction when the photovoltaic panel 5 is installed;

[0045] After the photovoltaic panel 5 has completed the tilt adjustment and rotation adjustment, since the photovoltaic fixed support is inside the ditch, in order to avoid the impact of the rising water level inside the ditch on the photovoltaic, when there is too much water inside the ditch, the float 16 will generate buoyancy, and then the support plate 6 will drive the support column 2 to slide upward inside the column 1, and the photovoltaic panel 5 can be adjusted in height according to the water level inside the ditch, and the float 16 is connected to the support plate 6 through the connecting piece 17, and the connecting piece 17 can be connected to the support plate 6 through the bolt 18, so that the operator only needs to remove the bolt 18 to remove and replace the float 16 and the support plate 6;

[0046] Similarly, the fixing bracket is inside the ditch. Considering that it is difficult to handle the snow on the photovoltaic panel 5 in rainy and snowy weather, the motor 27 can drive the screw 24 inside one of the mounting grooves 25 to rotate, so that the threaded block 32 drives one of the threaded rods 28 to move. Under the action of the adjustment plate 29, the slider 33 slides and guides outside the slide rod 26, and then the movement of the adjustment plate 29 can drive the cleaning plate 30 to fit the surface of the photovoltaic panel 5 for cleaning, so as to avoid dust or snow on the surface of the photovoltaic panel 5 affecting the use of the photovoltaic panel 5.

[0047] The two ends of the adjustment plate 29 can slide outside the two threaded rods 28, so that the height of the adjustment plate 29 can be adjusted, and the cleaning plate 30 at the bottom of the adjustment plate 29 can be fitted to the surface of the photovoltaic panel 5. The adjustment plate 29 can be easily slid out from the outside of the threaded rod 28 for disassembly, and the limit nut 31 can be rotated on the external thread of the threaded rod 28 to limit and fix the adjusted adjustment plate 29.

[0048] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
