Description

Technical Field

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

[0040] 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:

[0042] In this embodiment, if Figure 3 As shown, adjacent sliding blocks 52 are arranged at intervals along the left-right direction, and the transverse direction is the extending direction of the sliding slot 41 .

[0043] 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.

[0044] In this embodiment, if Figure 1 As shown, a photovoltaic assembly of the utility model includes a pile foundation 3, the lower end of the pile foundation 3 is used to be fixed on the seabed, a photovoltaic bracket 1 is installed on the upper end of the pile foundation 3, a photovoltaic panel 2 is installed on the photovoltaic bracket 1, and the photovoltaic bracket 1 is arranged in an inclined manner with the upper part higher and the lower part lower. In this embodiment, on the photovoltaic bracket 1, four photovoltaic panels 2 are arranged in sequence in the horizontal direction. Of course, in other embodiments, on a photovoltaic bracket 1, the actual number of photovoltaic panels 2 can be set according to actual needs, such as 2, 3, 5, etc., or only one can be set.

[0045] In this embodiment, the photovoltaic assembly further includes a mobile bird-repelling device for the photovoltaic assembly (hereinafter referred to as the bird-repelling device). Figure 1 , 2As shown in Figure 3, the bird-repellent device includes two mounting seats 4 that are placed on two opposite side frames of the photovoltaic component. Specifically, one of the mounting seats 4 is arranged on the frame at the upper end of the photovoltaic bracket 1, and the extension direction of the mounting seat 4 is parallel to the length direction of the frame. The other mounting seat 4 is arranged on the frame at the lower end of the photovoltaic bracket 1 and is symmetrically arranged with the mounting seat 4 at the upper end.

[0046] The bird-repelling device further includes a bird-repelling rod 5 disposed between the two mounting seats 4, and the upper end of the bird-repelling rod 5 is slidably mounted on the upper mounting seat 4, and the lower end of the bird-repelling rod 5 is slidably mounted on the lower mounting seat 4, so that the bird-repelling rod 5 as a whole can slide in the lateral direction. Birds generally reside on the upper side of the photovoltaic bracket 1, that is, the upper mounting seat 4 position. When birds reside, the bird-repelling rod 5 can be used to drive away the birds by moving the bird-repelling rod 5.

[0047] In this embodiment, the bird-repelling device also includes a driving mechanism 6 and a sensing mechanism (not shown in the figure). The sensing mechanism is electrically connected to the driving mechanism 6. The driving mechanism 6 is used to drive the bird-repelling rod 5 to slide on the mounting seat 4. The sensing mechanism is used to sense whether foreign objects such as birds have fallen on the photovoltaic module. When foreign objects have fallen on the photovoltaic module, the sensing mechanism transmits a signal to the control system, and the control system controls the driving mechanism 6 to drive the bird-repelling rod 5 to repel birds.

[0048] Preferably, in this embodiment, the sensing mechanism is a pressure sensor disposed on the photovoltaic support 1. When a bird lands on the photovoltaic support 1 or the photovoltaic panel 2, the change in gravity triggers a pressure change in the pressure sensor, thereby completing foreign object sensing.

[0049] In this embodiment, a sliding track is provided on each of the two mounting seats 4. The two sliding tracks are symmetrically arranged and extend laterally. The bird-repelling rod 5 includes a bird-repelling rod body 51 and two sliding blocks 52 disposed at both ends of the bird-repelling rod body 51. The two sliding blocks 52 are respectively slidably provided on the sliding tracks on the corresponding sides.

[0050] Specifically, in the present embodiment, the sliding track is a sliding groove 41 provided on the mounting seat 4, the sliding block 52 is slidably arranged in the sliding groove 41, and the size of the sliding block 52 is adapted to the size of the sliding groove 41, the upper end of the sliding block 52 extends out of the sliding groove 41, and the end of the bird-repelling rod body 51 is fixed to the part of the sliding block 52 extending out of the sliding groove 41, so that the sliding block 52 can drive away the birds that land on the mounting seat 4 while sliding.

[0051] In this embodiment, the driving mechanism 6 includes a driving motor 61 and a driving screw 62 arranged on at least one side mounting seat 4. The axial direction of the driving screw 62 is parallel to the extension direction of the sliding track. A threaded through hole matching the driving screw 62 is provided on the sliding block 52 on the side of the bird-repelling rod 5 facing the driving screw 62. The driving motor 61 and the driving screw 62 are coaxially arranged.

[0052] Specifically, in this embodiment, Figure 3 , 4 5, the driving mechanism 6 includes a driving motor 61 and a driving screw 62 disposed in the lower sliding groove 41, and a guide rod 63 disposed in the upper sliding groove 41. Of course, in other embodiments, the driving motor 61 and the driving screw 62 can be disposed in the upper sliding groove 41, and the guide rod 63 can be disposed in the lower sliding groove 41.

[0053] The driving motor 61 is fixed to the left side of the lower sliding groove 41, and the axis of the rotating shaft of the driving motor 61 extends in the horizontal direction. The driving screw 62 extends in the horizontal direction as a whole, and the left end of the driving screw 62 is fixedly mounted on the driving motor 61, and the right end of the driving screw 62 is rotatably mounted on the right end of the lower sliding groove 41. On the lower sliding block 52, a threaded through hole matching the driving motor 61 is provided at the position corresponding to the driving screw 62, and the sliding block 52 and the driving motor 61 are threadedly matched to form a screw nut mechanism, so that the driving screw 62 is driven to rotate through the driving motor 61, and then the sliding block 52 is driven to slide along the sliding groove 41.

[0054] The axis of the guide rod 63 extends in the transverse direction, and the two ends of the guide rod 63 are respectively installed at the left and right ends of the upper sliding groove 41, and the sliding block 52 on this side is provided with a through hole adapted to the guide rod 63, and the sliding block 52 on this side is penetrated on the guide rod 63 and can slide along the guide rod 63. In this way, driven by the driving motor 61, the upper and lower sliders can synchronously slide along the sliding groove 41 on the corresponding side, thereby driving the bird-repelling rod body 51 to slide, thereby achieving bird-repelling.

[0055] In this embodiment, a plurality of bird-repelling rods 5 are arranged between the two mounting seats 4. Specifically, in this embodiment, the number of the bird-repelling rods 5 corresponds to the number of the photovoltaic panels 2, and a bird-repelling rod 5 is arranged above each photovoltaic panel 2.

[0056] like Figure 3 , 4 As shown in Figures 5 and 6, the driving screw 62 includes a plurality of thread segments 621 arranged at intervals, and the rotation directions of adjacent thread segments 621 are opposite, the number of thread segments 621 is consistent with the number of photovoltaic panels 2, and the lateral length of the thread segment 621 corresponds to the lateral length of a photovoltaic panel 2, so that one thread segment 621 can be set on one photovoltaic panel 2, and one bird-repelling rod 5 can be arranged on one photovoltaic panel 2.

[0057] In this embodiment, the number of photovoltaic panels 2 is four, so the number of bird-repelling rods 5 and threaded segments 621 is also four, and the sliding blocks 52 at the lower ends of the four bird-repelling rods 5 are threadedly connected to the four threaded segments 621 one by one. The driving motor 61 is a forward and reverse motor, so that when the driving motor 61 drives the driving screw 62 to rotate, the adjacent bird-repelling rods 5 can move synchronously toward or away from each other, and then use one driving motor 61 to drive all the bird-repelling rods 5 to slide and radiate all the photovoltaic panels 2. At the same time, the forward and reverse motors can drive the driving screw 62 to rotate in the forward and reverse directions, and then drive the bird-repelling rods 5 to reciprocate, thereby improving the bird-repelling effect.

[0058] Of course, in other embodiments, the number of bird-repelling rods 5 can be set according to actual needs, such as one threaded section 621 covers two photovoltaic panels 2, and the two photovoltaic panels 2 drive birds through one bird-repelling rod 5. Of course, in other embodiments, when the actual needs are met, the overall rotation direction of the driving screw 62 can be the same. At this time, when installed, the bird-repelling rods 5 are arranged on the driving screw 62 at equal intervals, and the intervals are the lateral length of the photovoltaic panel 2. When the driving screw 62 rotates, all the bird-repelling rods 5 move synchronously in the same direction. Or in other embodiments, when the actual needs are met, only one bird-repelling rod 5 can be set, and the movement range of one bird-repelling rod 5 covers all photovoltaic panels 2.

[0059] In this embodiment, if Figure 6 As shown, preferably, the driving screw 62 further includes a smooth transition section 622 disposed between adjacent thread sections 621, and a support block 7 is fixedly disposed at a position of the sliding groove 41 corresponding to the smooth transition section 622, and the smooth transition section 622 passes through the support block 7 and is rotatably mounted on the support block 7. In this way, on the one hand, the support block 7 can be used to support the driving screw 62 to improve stability, and on the other hand, the support block 7 can be used to limit the movement of the sliding block 52 to avoid collision when adjacent sliding blocks 52 move toward each other, thereby improving safety and service life.

[0060] In this embodiment, if Figure 2 As shown, a cleaning brush 8 is also provided on the side of the driving rod facing the photovoltaic panel 2. The cleaning brush 8 is a flexible brush, and its lower end abuts against the photovoltaic panel 2. The cleaning brush 8 can be used to clean foreign matter on the surface of the photovoltaic panel 2 while the bird-repelling rod 5 slides, thereby preventing accumulation of debris from affecting power generation.

[0061] In this embodiment, an anti-staying block (not shown in the figure) is further provided at the upper end of the sliding block 52 . Specifically, the anti-staying block is a conical structure with a pointed top, which can prevent birds from staying on the sliding block 52 .

[0062] In summary, the bird-repelling device of the present invention, by slidingly setting the two ends of the bird-repelling rod 5 on the mounting seat 4 on the corresponding side, when a bird lands on the photovoltaic component, the bird-repelling rod 5 moves back and forth on the photovoltaic panel 2, which can drive the bird away and prevent the bird from staying for a long time. At the same time, this method will not harm the bird. By using the sensing device, when the bird lands on the photovoltaic component, the bird-repelling rod 5 can be automatically controlled to move, thereby realizing automation and improving practicality.

[0063] Embodiment 2: This embodiment provides a different sliding track. Different from Embodiment 1, in this embodiment, when meeting actual needs, the sliding track is an I-shaped track, and a notch adapted to the I-shaped track is provided at the lower end of the sliding block. The sliding block is integrally clamped on the I-shaped track and can slide along the I-shaped track. At this time, two support blocks are respectively provided at both ends of the I-shaped track, and the two ends of the guide rod are respectively provided on the two support blocks of the upper I-shaped track, and the driving motor is fixed on a support block of the lower I-shaped track, and the end of the driving screw is facing away from the driving motor and is rotatably provided on another support block of the lower track.

[0064] Embodiment 3: This embodiment provides a different driving mechanism. Different from Embodiment 1, in this embodiment, the driving mechanism includes two driving gears and a driving chain. The two driving gears are disposed on the left and right sides of one photovoltaic bracket, and the axes of the driving gears are vertically arranged on the upper side of the photovoltaic bracket. The driving chain is wound around the two driving gears, and the bird-repelling rod is fixed on the driving chain. When the driving gear rotates, the driving chain and the bird-repelling rod are fixed at a position that moves laterally, and the driving motor drives the driving gear to rotate forward and reverse, thereby driving the bird-repelling rod to move back and forth laterally to complete the bird-repelling.

[0065] Example 4: This example provides a different driving mechanism and sensing mechanism. Different from Example 1, a guide rod, a driving motor and a driving screw are provided at the position of each photovoltaic panel, so that one bird-repelling rod is only responsible for the area of ​​one photovoltaic panel. At this time, the sensing mechanism is an infrared sensing device. On the mounting base, separate infrared sensing devices are provided corresponding to the positions of the four photovoltaic panels. The infrared sensing devices at the corresponding positions are electrically connected to the driving mechanisms at the corresponding positions. In this way, when a bird lands, the movement of the driving rod in the bird landing area can be controlled individually to reduce energy loss.

[0066] Embodiment 5: This embodiment provides a different driving mechanism. Different from Embodiment 1, a driving motor and a driving screw are provided in the sliding grooves on the upper and lower sides, and the two driving motors synchronously drive the driving screw to rotate, thereby driving the driving rod to move.

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.
