DETAILED DESCRIPTION OF THE INVENTION

[0019] The technical solutions of the present invention will be further described below with reference to the accompanying drawings.

[0020] As Figures 1 to 5As shown in the figure, a bird aggregation prevention device for a power distribution cabinet according to the present invention includes a bird aggregation prevention device and a power supply device. The bird aggregation prevention device includes a shape memory alloy sheet 1, an arc-shaped cover 2, and a heating device 3. The arc-shaped cover 2 is arc-shaped. The shape memory alloy sheet 1 is attached to the surface of the arc-shaped cover 2 at room temperature, as Figure 1 shown. The heating device 3 is attached to the inner layer of the arc-shaped cover 2.

[0021] As Figure 2 shown, the heating device 3 of the present invention includes a rubber layer 32, a heating layer 33, a conductive wire 34, and a polyester layer 35. The conductive wires 34 are arranged on both sides of the heating layer 33. After the conductive wires 34 are connected to the power supply, the heating device 3 generates heat. The heating layer 33 of the present invention can be an electric heating wire. That is, through the electric heating wire, the polyester layer 35 is attached to the inner side of the arc-shaped cover 2, and the electric heating wire is pressed against the polyester layer 35 through the rubber layer 32. The rubber layer 32 and the polyester layer 35 ensure that the whole device is insulated from the outside during operation, so that the device of the present invention can be used in high-voltage power distribution equipment. The temperature range of the heating device 3 of the present invention is determined according to the deformation temperature of the shape memory alloy sheet 1. For example, if the deformation temperature of the shape memory alloy sheet 1 is 60 °C, the temperature of the heating device should be higher than 60 °C, such as more than 80 °C, to ensure that the shape memory alloy sheet 1 can deform under the condition of external air cooling. As Figure 4 and Figure 5 shown, the shape memory alloy sheet 1 of the present invention is arranged on the arc-shaped cover 2 in a sheet form and opens upward in the heating state, so as to prevent the fixation of bird nests on the power distribution equipment. And through heating, the bird droppings remaining on the surface of the equipment can be dried and fallen off, ensuring no peculiar smell is generated.

[0022] As Figure 2 and Figure 3 shown, the heating layer 33 of the present invention is a graphene composite coating. The heating device 3 further includes a reflective film 31. The rubber layer 32 is a flexible rubber. In this way, during the manufacturing process of the heating device 3, the reflective film, the flexible rubber, the graphene composite coating, the conductive wire, and the polyester can be sequentially stacked and roll-pressed. The present invention can set the radian of the heating device 3 according to the radian of the arc-shaped cover 2 during the roll-pressing process. As Figure 3 shown, when using the graphene composite coating, the conductive wire is powered by a semi-circular arc surface. A plurality of conductive wires are arranged on both sides of the graphene composite coating, and the conductive wires are in contact with the graphene composite coating for power supply. The rubber layers and the polyester layer 35 on both sides play a role in fixing the conductive wires while being insulated, making the whole device of the present invention flexible and convenient to be fixed on the inner side of the arc-shaped cover 2. The reflective film 31 can be a tin foil, so as to emit heat towards the direction of the arc-shaped cover 2.

[0023] As Figure 1 and Figure 5As shown in the figure, the power supply device of the present invention includes an inner shielding plate 5, inner iron oxide 6, inner acrylic plate 7, transmitting coil 8, outer shielding plate 9, outer iron oxide 10, outer acrylic plate 11, and receiving coil 12. The inner shielding plate 5 is installed at the lower part of the upper shell 4 of the power distribution cabinet, and the outer shielding plate 9 is installed at the upper part of the upper shell 4 of the power distribution cabinet. The inner shielding plate 5 forms a cavity and sequentially installs the inner iron oxide 6, inner acrylic plate 7, and transmitting coil 8. The outer shielding plate 9 forms a cavity and sequentially installs the outer iron oxide 10, outer acrylic plate 11, and receiving coil 12. The outer shielding plate 9 and inner shielding plate 5 of the present invention can be made of aluminum plates, which have strong load-bearing capacity and can effectively shield electromagnetic signals, ensuring that the electromagnetic coupling signals generated by the internal coils of this power supply device do not interfere with the normal communication of residents. The inner acrylic plate 7 and outer acrylic plate 11 of the present invention can play an insulating role to ensure that the upper shell 4 of the power distribution cabinet is not charged. The inner iron oxide 6 and outer iron oxide 10 of the present invention increase the coupling effect between the transmitting coil and the receiving coil, improving the power conversion efficiency.

[0024] As Figure 7 shown in the figure, the present invention may include a receiving circuit. The receiving circuit includes a rectifier bridge circuit 13, a voltage stabilizing circuit 14, and a fuse D. The output of the receiving coil 12 is connected to the rectifier bridge circuit 13. After passing through the rectifier bridge circuit 13, the alternating current is converted into direct current, and then after passing through the voltage stabilizing circuit 14, it is connected to the heating device 3 to realize the power supply to the heating device. Among them, the voltage stabilizing circuit 14 may also be provided with a fuse D to protect the circuit. The receiving circuit and the generating circuit of the present invention can adopt various general wireless charging circuits.

[0025] The device of the present invention can be used on the already built power distribution cabinet. It only needs to re-fix the device inside and outside the equipment, without the need to draw wires from the inside to the power distribution cabinet. The heating device 3 can operate in the DC low-voltage range, and the device of the present invention adopts insulation means. Therefore, after the present invention is installed, it can ensure that the overall power distribution cabinet will not carry dangerous voltage due to the addition of this device, and the already built power distribution cabinet can be upgraded and transformed.

[0026] Finally, it should be noted that the above specific embodiments are only used to illustrate the technical solutions of the present patent technology and not to limit them. Although the present patent technology has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present patent technology can be modified or equivalently replaced without departing from the spirit and scope of the technical solutions of the present patent technology, and they should all be covered within the scope of the claims of the present patent technology.
