Description

Technical Field

[0001] The utility model relates to the technical field of photovoltaic equipment, and in particular to a rotary bird-repelling device for a photovoltaic component and a photovoltaic component. Background Art

[0002] Current photovoltaic power stations, especially those on water surfaces or near bird habitats, are often disturbed by bird droppings. Photovoltaic power stations are mostly located in open areas, and the frame on the higher side of the photovoltaic module (i.e. the upper frame of the photovoltaic bracket) is very suitable for birds to stay on, which will lead to bird droppings remaining on the module. The obstruction of bird droppings will not only corrode the surface of the module, but also cause hot spot effects on the photovoltaic panels on the photovoltaic bracket, which may even burn the module in severe cases.

[0003] To address the problem of bird repelling, currently the main approach is to install bird repellent devices near photovoltaic power stations. Traditional bird repellent devices are mainly divided into environmentally friendly and non-environmentally friendly types. Environmentally friendly types include reflectors, bird spikes, wind-blown whistles, buzzers simulating the sounds of natural enemies, etc. The first few types can only be triggered when there is wind or sunshine, while simulating the sounds of natural enemies can easily make birds adapt, causing noise pollution and the bird repellent effect is not obvious. Non-environmentally friendly types mainly include ultrasonic bird repellents, laser bird repellents, bird repellents, etc., which are harmful to the bodies of birds and are not suitable for long-term use in bird habitats, and are likely to cause damage to the ecology.

DETAILED DESCRIPTION

[0034] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present application: Specific embodiment 1:

[0036] In this embodiment, if Figure 1 As shown, the length direction of the upper frame of the photovoltaic support 8 is horizontal, that is, left-right, and the support blocks 1 are arranged at intervals along the horizontal direction.

[0037] In this embodiment, the photovoltaic module of the utility model is a pile-based photovoltaic module, and the application scenario is at sea. In the marine environment, after birds settle, on the one hand, it is easy to block the photovoltaic panel, affecting the power generation efficiency, and on the other hand, birds are easy to leave foreign objects such as bird droppings on the photovoltaic panel, which is time-consuming and labor-intensive for staff to clean, which is extremely inconvenient. Therefore, the photovoltaic module of the present application can be used to drive away birds, avoid birds from staying, and reduce bird interference. Of course, in other embodiments, the photovoltaic module of the present application can also be a floating photovoltaic module without pile foundation at sea, or a photovoltaic module used on land. This embodiment is only an example and does not limit the actual application scenario.

[0038] refer to Figures 1 to 4 The utility model provides a photovoltaic assembly, including a pile foundation 7, a photovoltaic bracket 8 is fixedly mounted on the upper end of the pile foundation 7, a photovoltaic panel 9 is mounted on the photovoltaic bracket 8, and the photovoltaic bracket 8 is arranged in an inclined manner with the upper part being higher and the lower part being lower. The photovoltaic assembly also includes a rotating bird-repelling device for the photovoltaic assembly (hereinafter referred to as the rotating bird-repelling device) arranged on the photovoltaic bracket 8.

[0039] like Figure 1 , 2As shown, the rotary bird-repellent device includes a support base, which is used to be fixed on the upper frame of the photovoltaic bracket 8. A rotating rod 3 is rotatably arranged on the support base, and the axis of the rotating rod 3 extends along the length direction of the upper frame of the photovoltaic bracket 8. It also includes a driving mechanism, which is used to drive the rotating rod 3 to rotate to repel birds.

[0040] Preferably, in this embodiment, the support seat includes at least two support blocks 1 arranged at intervals, and the lower ends of the support blocks 1 are fixed to the upper frame of the photovoltaic bracket 8. A rotating rod 3 is provided between each of the adjacent support blocks 1. The spacing between the adjacent support blocks 1 is used to match the lateral size of the photovoltaic panel 9, and the number of the rotating rods 3 is used to match the number of the photovoltaic panels 9.

[0041] Specifically, Figure 1 , 2 As shown, in this embodiment, four photovoltaic panels 9 are arranged at intervals along the lateral direction on the photovoltaic bracket 8, and five support blocks 1 are arranged at intervals along the lateral direction. The five support blocks 1 divide four interval areas, and a rotating rod 3 is arranged in each interval area. A driving mechanism is arranged on each rotating rod 3, so that the rotating rods 3 correspond to the photovoltaic panels 9 one by one.

[0042] Of course, in other embodiments, the number of photovoltaic panels 9 can be set according to actual needs, such as 2, 3, 5, etc. At this time, the number of support blocks 1, the intervals between adjacent support blocks 1, and the number of rotating rods 3 can all be adaptively adjusted according to the number of photovoltaic panels 9 and the lateral length of the photovoltaic panels 9.

[0043] Or in other embodiments, the support seat may only include two support blocks 1, which are placed at the lateral ends of the upper frame of the photovoltaic bracket 8, and the rotating rod 3 spans the entire upper frame. In this case, one rotating rod 3 is used to complete the bird-repelling work. At the same time, in order to ensure the stability of the rotating rod 3, multiple support plates can be arranged at intervals on the upper frame of the photovoltaic bracket 8, and the rotating rod 3 is inserted into the support plate and rotates with the support plate. In other embodiments, the support seat can be a long strip structure that spans the upper frame of the photovoltaic bracket 8 as a whole. In this case, multiple block-shaped protrusions are arranged at intervals on the support seat, and the rotating rod 3 is rotatably installed between adjacent block-shaped protrusions.

[0044] like Figure 3 , 4 As shown, the driving mechanism is a driving motor 4, and the opposite surfaces of the adjacent support blocks 1 are respectively provided with a fixing hole 11 for the driving motor 4 and a rotating hole 12 for the rotating rod 3, that is, Figure 2As shown, fixing holes 11 and rotating holes 12 are respectively provided on the opposite sides of the support blocks 1 at the two lateral ends, and fixing holes 11 and rotating holes 12 are respectively provided on both sides of the support block 1 at the middle position. In this way, the support block 1 at the middle position plays a role in fixing the drive motor 4 and also plays a role in rotating and installing the rotating rod 3, thereby improving compactness, saving materials and reducing weight.

[0045] Specifically, in this embodiment, four fixing holes 11 are arranged in a circumferential array, one end of the drive motor 4 is fixed in the fixing hole 11 of the left support block 1 by a fixing bolt, and the other end is the output shaft of the drive motor 4, the output shaft is coaxially arranged with the rotating rod 3, one end of the rotating rod 3 facing the drive motor 4 is locked with the output shaft, and the other end of the rotating rod 3 is rotatably mounted in the rotating hole 12 of the right support block 1 through the bearing 5. In other embodiments, the fixing hole 11 can be a countersunk hole adapted to the drive motor 4, and the end of the drive motor 4 facing away from the rotating rod 3 is inserted into and fixed in the countersunk hole.

[0046] Preferably, in this embodiment, the rotary bird-repelling device further includes a sensing device, which is used to sense whether there are birds staying on the rotating rod 3. When there are birds staying on the rotating rod 3, the control system controls the driving mechanism to rotate, thereby driving the rotating rod 3 to rotate, thereby completing the bird-repelling. This can achieve automation and improve practicality.

[0047] Preferably, in this embodiment, the sensing device is an infrared sensing device 6, such as Figure 2 , 3 As shown, the infrared sensing device 6 includes a transmitting end 61 and a receiving end 62, and both the transmitting end 61 and the receiving end 62 are arranged above the rotating rod 3, and the connecting line between the transmitting end 61 and the receiving end 62 is parallel to the axis of the rotating rod 3. In this way, it can sensitively sense whether there are birds landing and staying on the rotating rod 3, thereby improving practicality and sensitivity. In this embodiment, a group of infrared sensing devices 6 are arranged between adjacent support blocks 1. At the same time, in this embodiment, the rotating rod 3 corresponds to the photovoltaic panel 9 one by one, so that the photovoltaic assembly can be divided into areas according to the position of the photovoltaic panel 9, and then the birds staying in a specific area can be expelled in a targeted manner, thereby reducing costs and improving practicality.

[0048] Of course, in other embodiments, only one set of infrared sensing devices 6 may be provided, and in this case, the transmitting end 61 and the receiving end 62 are respectively provided at the top of the support block 1 at both ends, or the transmitting end 61 and the receiving end 62 are provided on the side of the support block 1 adjacent to the rotating rod 3. It is ensured that there is no obstruction between the transmitting end 61 and the receiving end 62, and the length of the perpendicular line between the connecting line between the transmitting end 61 and the receiving end 62 and the axis of the rotating rod 3 is not greater than the size of the bird in this direction, so as to ensure that the bird can be identified. At this time, when a bird stops, all the rotating rods 3 rotate synchronously to prevent the bird from intermittently landing on different rotating rods 3.

[0049] In other embodiments, the sensing device may also be a pressure sensing device, which includes a pressure sensor, and a pressure sensor is provided between the lower end of each support block 1 and the upper frame of the photovoltaic bracket 8. When a bird stays on a rotating rod 3, the weight on the support blocks 1 at both ends of the rotating rod 3 will change, and at this time, the pressure sensors at the lower ends of the two support blocks 1 will sense the pressure change. The control system locks the rotating rod 3 where the bird stays by judging the positions of the two pressure sensors that have changed, and then drives the driving motor 4 of the rotating rod 3 to rotate, thereby completing the bird driving.

[0050] Preferably, in this embodiment, Figure 1 , 3 As shown, the upper end of the support block 1 is fixedly mounted with an anti-staying block 2, and the upper end of the anti-staying block 2 is a pointed tip. Specifically, in this embodiment, the support block 1 is a quadrangular prism structure, and the anti-staying block 2 is a quadrangular pyramid structure, and the lower end surface of the quadrangular pyramid structure is adapted to the upper end surface of the support block 1. Of course, in other embodiments, the support block 1 may be a cylindrical structure, and the anti-staying block 2 is a conical structure. This can prevent birds from staying on the support block 1.

[0051] In summary, in the actual use environment of photovoltaic components, birds usually stay on the upper frame of the photovoltaic bracket 8. The rotary bird-repellent device of the utility model is provided with a rotating rod 3 on the support seat, and the support seat is provided on the upper frame of the photovoltaic bracket 8. The rotating rod 3 can be used to cover the upper frame area, forcing the birds to stay on the rotating rod 3. The driving mechanism is used to drive the rotating rod 3 to rotate. The rotation of the rotating rod 3 can drive away the birds that fall on the rotating rod 3, thereby preventing the birds from staying, thereby preventing the birds from interfering with the power generation of the photovoltaic panel 9, and at the same time will not cause harm to the birds.

[0052] The embodiment of the rotary bird-repellent device for photovoltaic modules of the present invention is the same as the rotary bird-repellent device for photovoltaic modules in the above-mentioned photovoltaic modules, and will not be described in detail here.

For those skilled in the art, the present application may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
