Description

Technical Field

[0001] This utility model relates to the field of marine photovoltaic technology, and in particular to a marine floating photovoltaic anti-bird structure. Background Technology

[0002] Birds often perch on floating photovoltaic (PV) modules at sea, leaving behind droppings. If bird droppings accumulate on the PV modules over a long period, it can cause localized temperature increases, creating a "hot spot effect" that damages the solar cells. Furthermore, bird droppings are complex in composition and corrosive, easily causing chemical corrosion to the equipment's surface. They also affect the aesthetics and reduce the photoelectric conversion efficiency of the PV modules.

[0003] Currently, bird deterrence methods mainly fall into two categories. The first method involves using a device to identify nearby birds and then automatically activating ultrasonic or noise-based methods to scare them away. This method requires the installation of electronic equipment, which is costly, and the equipment is prone to damage under complex weather conditions at sea, requiring frequent maintenance. The second method involves installing bird-repelling frames outside the photovoltaic module area to attract birds and prevent them from landing on the photovoltaic modules. However, the support structures for this method are generally complex, making them difficult to manufacture, and some bird-repelling frames also have mechanical structures that are susceptible to fatigue damage under the influence of sea winds and the turbulence of the floating structure.

[0004] Therefore, there is an urgent need for a floating photovoltaic bird-proof structure that can not only effectively prevent birds from landing on photovoltaic modules, but also effectively prevent bird droppings from corroding the photovoltaic modules. Utility Model Content

Detailed Implementation

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0025] Example 1

[0026] Reference Figures 1-4 This utility model discloses a floating photovoltaic bird-prevention structure for sea use, including a float 1, a number of support frames 2 fixedly connected to the float 1, a number of photovoltaic modules 3 installed on the support frames 2, a number of bird-prevention components for preventing birds from landing between adjacent support frames 2, and a bird-prevention component corresponding to a number of photovoltaic modules 3 on a support frame 2. Bird-prevention components for allowing birds to land are provided on the side of the two outermost support frames 2 away from the adjacent support frames 2.

[0027] The floating photovoltaic system uses a float 1 to support the photovoltaic modules 3 floating on the water surface. The solar panels convert light energy into electrical energy, which is then converted into alternating current by an inverter and transmitted to the power grid or user end via an underwater cable.

[0028] Support frame 2 adopts a flexible photovoltaic support system. The flexible photovoltaic support system is a large-span, multi-span system that uses prestressed steel strands, steel wire ropes or polymer materials as the main support structure. Its core design includes the tension cable structure between the two fixed points (rigid columns) and the intermediate support or cable system, forming a load-bearing system that combines rigidity and flexibility.

[0029] This invention effectively prevents birds from landing between adjacent support frames 2 through the bird-prevention component; at the same time, the bird-landing component, which is set on the side of the two outermost support frames 2 away from the adjacent support frames 2, provides a place for birds to land, and the bird droppings produced by the birds can fall directly into the sea through the bird-prevention component and the bird-landing component; this invention, through the bird-prevention component and the bird-landing component, can not only effectively prevent birds from landing on the photovoltaic module 3, but also effectively prevent bird droppings from corroding the photovoltaic module 3.

[0030] The solution is further optimized. The bird-prevention component includes symmetrically arranged fixed plates 42. Multiple cables 4 are fixedly connected between the two fixed plates 42. The fixed plates 42 are rotatably connected to connecting rods 43 via rotating shafts 41. The end of the connecting rod 43 away from the rotating shaft 41 is fixedly connected to the support frame 2.

[0031] Because the spacing between the photovoltaic modules on the adjacent support frame 2 is small, the bird-proof components can effectively prevent bird droppings from falling onto the photovoltaic modules 3.

[0032] When a bird is attracted to the cable 4 and lands on it, the bird's weight causes a shift in its center of gravity, causing the cable 4 to move downwards. The cable 4 then causes the fixing plate 42 to rotate around the rotating shaft 41. This movement of the cable 4 startles the bird, causing it to fly away from the cable 4.

[0033] In a further optimized design, multiple cables 4 are arranged at equal intervals in a circle, and the central axis of the circle formed by the multiple cables 4 is on the same central axis as the central axis of the rotating shaft 41. The rotating shaft 41 enables the cables 4 to effectively drive the fixed plate 42 to rotate.

[0034] The design was further optimized so that the bottom of the lowest cable 4 is higher than the top surface of the photovoltaic module 3. Since birds generally prefer heights, having the bottom of the lowest cable 4 higher than the top surface of the photovoltaic module 3 effectively prevents birds from perching on the photovoltaic module 3.

[0035] In a further optimized design, the bird-landing component includes end support rods 51 mounted on both ends of the support frame 2, with a crossbar 5 positioned between the two end support rods 51. The crossbar 5 provides a landing spot for the birds.

[0036] To prevent bird droppings from birds perched on the crossbar 5 from falling onto the photovoltaic module 3, the crossbar 5 is positioned above the outer side of the float 1, allowing the bird droppings to fall directly into the sea.

[0037] The design was further optimized so that the bottom surface of the crossbar 5 is higher than the top surface of the photovoltaic module 3. Since birds generally prefer heights, having the bottom surface of the crossbar 5 higher than the top surface of the photovoltaic module 3 effectively prevents birds from perching on the photovoltaic module 3.

[0038] In a further optimized design, one end of the end support rod 51 is detachably connected to the support frame 2 via a connecting plate 511, and the other end of the end support rod 51 is provided with a first through hole 512, which is detachably connected to the end of the crossbar 5.

[0039] The connecting plate 511 is connected to the support frame 2 by self-tapping screws. The end of the crossbar 5 that extends into the first through hole 512 is installed in the first through hole 512 of the end support rod 51 by self-tapping screws. The self-tapping screws facilitate the quick installation of the crossbar 5 and the connecting plate 511.

[0040] In a further optimized design, multiple mid-span support rods 52 are provided between the two end support rods 51. A second through hole 522 is provided on the mid-span support rod 52, and the crossbar 5 passes through the second through hole 522.

[0041] By inserting the crossbar 5 into the second through hole 522, multiple mid-span support rods 52 can effectively support the crossbar 5, so that the height of the bottom of the crossbar 5 at each point is higher than the height of the top surface of the photovoltaic module 3.

[0042] In a further optimized design, the end of the mid-span support rod 52 furthest from the crossbar 5 is detachably connected to the support frame 2. Multiple bolt holes 521 are provided at the end of the mid-span support rod 52 furthest from the crossbar 5, and bolts are threaded into these bolt holes 521, facilitating the quick installation of the mid-span support rod 52 onto the support frame 2.

[0043] Example 2

[0044] Reference Figure 2 The difference between this embodiment and the first embodiment is that the fixing plate 42 is an equilateral triangle and the cable 4 is installed at the sharp corner of the fixing plate 42. When a bird lands on any cable 4, it will cause the center of gravity of the fixing plate 42 to shift, causing the fixing plate 42 to rotate around the rotation axis 41. The movement of the cable 4 can startle the bird and make it fly away from the cable 4.
