Description

Technical Field

[0001] The utility model relates to the technical field of photovoltaic power generation equipment, in particular to a floating photovoltaic power generation panel. Background Art

[0002] Water photovoltaic power stations use water-based platforms to float photovoltaic modules on the water surface to generate electricity, such as on the surface of reservoirs and swamps. The characteristics are that they do not occupy land resources. The water body has a cooling effect on photovoltaic modules, which can suppress the rise in the surface temperature of the modules, thereby obtaining higher power generation. In addition, covering the solar panels on the water surface can also reduce the evaporation of the water surface, inhibit the reproduction of algae, and protect water resources. Under current technology, floating photovoltaic panels only need to be inflated and placed on the water surface when installed. No additional support structure is required for photovoltaic power generation. The production cost is low and the installation is easy. However, after the photovoltaic panels are placed, the device cannot adjust the placement angle of the photovoltaic panels. When the photovoltaic panels are not directly exposed to the sun, the power generation efficiency of the photovoltaic panels is affected. In view of this, we propose a floating photovoltaic panel.

Since the two hinged rods 35 are cross-arranged and the two screw sleeves 34 are symmetrically arranged about the center of the two-way threaded screw 32, the connection between the two hinged rods 35 and the two-way threaded screw 32 is always on the same vertical line, so that the height of the two hinged rods 35 can be changed. The second drive assembly 4 includes a connecting plate 41, and a T-shaped slide groove 42 is provided inside the connecting plate 41. A T-shaped slider 43 is slidably arranged inside the T-shaped slide groove 42. When the two hinged rods 35 are connected, the two hinged rods 35 are connected to the second drive assembly 4. When the height of the rod 35 changes, it drives the T-shaped slider 43 to slide inside the T-shaped slide groove 42, so that the connecting plate 41 moves up and down. Two limit plates 45 are fixedly connected to the bottom end of the placement plate 15. A limit groove 46 is opened in the middle of the limit plate 45. The inner side of the limit groove 46 is provided with a limit wheel 44 rotatably arranged at both ends of the connecting plate 41. Since the relative position of the rotating shaft 14 and the placement plate 15 is fixed, when the connecting plate 41 moves up and down, the limit wheel 44 reciprocates inside the limit groove 46 and the limit wheel 44 always moves on the vertical plane, so that the placement plate 15 drives the photovoltaic panel 12 to adjust the rotation angle with the rotating shaft 14 as the center.

[0024] Rollers 36 are rotatably arranged on both sides of the screw sleeve 34, and roller grooves 37 are opened on both sides of the screw groove. The rollers 36 are rotatably arranged inside the roller grooves 37. When the bidirectional threaded screw 32 drives the screw sleeve 34 to move inside the screw groove, the rollers 36 roll inside the roller grooves 37 to reduce the friction between the screw sleeve 34 and the screw groove and extend the service life of the device. Rubber pads 38 are fixedly connected on both sides of the two screw sleeves 34 to prevent the bidirectional threaded screw 32 from excessively rotating and causing excessive squeezing of the two screw sleeves 34 to cause damage to the device.

[0025] The floating device 2 includes a lower bottom plate 21 arranged at the lower side of the upper bottom plate 11. The upper bottom plate 11 and the lower bottom plate 21 are connected by bolts. A plurality of arc plates 23 are fixedly connected to the bottom end of the upper bottom plate 11 and the top end of the lower bottom plate 21. Two adjacent arc plates 23 are on the same vertical plane. A rubber extrusion pad 24 is fixedly connected to the arc surface of two adjacent arc plates 23. When the bolts are tightened to fix the upper bottom plate 11 and the lower bottom plate 21, the arc plates 23 squeeze the sealed plastic barrel 25. A rubber extrusion pad 24 is arranged between the sealed plastic barrels 25 to prevent the arc plate 23 from over-extruding the sealed plastic barrel 25 and causing damage to the sealed plastic barrel 25. A sealed plastic barrel 25 is arranged between the two rubber extrusion pads 24. The sealed plastic barrel 25 has the advantages of good sealing and corrosion resistance, and is cost-effective. The bottom corners of the lower base plate 21 are fixedly connected with weight blocks 22 for increasing the balancing effect of the device. When the device is placed on the water surface, the gravity of the weight blocks 22 pulls the device down to improve the stability of the device.

[0026] When a floating photovoltaic power generation panel of this embodiment is used, the user rotates the rotating handle 33 to make the bidirectional threaded screw 32 drive the two screw sleeves 34 to move, and the two hinged rods 35 drive the connecting plate 41 to move up and down. At the same time, the limiting wheels 44 arranged at both ends of the connecting plate 41 are rotated to roll in the limiting plate 45 fixedly connected to the bottom end of the placement plate 15. Since the relative positions of the rotating shaft 14 and the limiting plate 45 are fixed, the placement plate 15 moves on an arc surface with the rotating shaft 14 as the center and the straight-line distance between the rotating shaft 14 and the limiting wheel 44 as the radius, and the angle of the photovoltaic power generation panel 12 is adjusted to make the sunlight directly hit its surface, so that the photovoltaic power generation panel 12 can absorb light energy to the maximum extent, thereby improving its power generation efficiency.
