All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
10kV electric power tower is important infrastructure in the distribution lines, provides support and guarantee for the operation of electric wire netting, simultaneously because electric power tower structure is firm and safe disguise is good, birds like the selection to nest on it and go home. However, birds live on the tower and are defecated on the surfaces of insulators and other equipment, so that the insulation of the equipment is reduced, the short-circuit tripping fault of a line is easily caused, and certain hidden danger is brought to the safe operation of a power grid. The bird repelling mode commonly used in the prior art mainly comprises the steps of cleaning bird nests and repelling bird groups by utilizing physical characteristics such as sound and light, however, the bird repelling mode and the bird repelling mode can not radically prevent nesting activities of birds on a tower for a long time. The invention can prevent birds from nesting on the tower from the source, thereby not only avoiding the operation and maintenance intensity and the working risk caused by bird nest cleaning, but also reducing the occurrence of line trip accidents from the source, and improving the stability of line operation and the power supply reliability while reducing the maintenance cost.
Referring to fig. 1, fig. 1 is a view showing an anti-bird nest device suitable for a 10kV distribution network iron tower according to an embodiment of the present invention, which includes a cylindrical main frame 1 and a closing plate, wherein the upper and lower ends of the main frame 1 are open and are respectively covered with the closing plate, and at least a portion of the upper and lower ends of the main frame 1 that are open is covered with the closing plate. Meanwhile, the size of the main body frame 1 is movably adjustable, namely the main body frame 1 can adjust the size of the main body frame according to the size of an iron tower, so that the density of the bird nest prevention device on the iron tower can be effectively improved, and the bird nesting space can be extruded as much as possible.
Specifically, as shown in fig. 3, the main body frame 1 is formed by winding a panel-shaped plate-shaped structure, the joints at two sides are fixedly connected by using the tie 7, and the bird's nest prevention device is directly fixed on an iron tower by using the 304 stainless steel tie 7, so that the bird's nest prevention device is simple in structure, convenient to operate, strong in plasticity of the tie, applicable to angle irons at various angles and in various sizes, and meanwhile, the 304 stainless steel material is corrosion-resistant, high-temperature-resistant, and stable and reliable in quality. Accordingly, the size of the main body frame 1 is determined according to the winding size of the plate-shaped structure, so that the size of the main body frame 1 can be flexibly adjusted according to the requirement of the site. Meanwhile, the side wall of the main body frame 1 is of a grid-shaped fence structure, so that the weight of the main body frame 1 can be effectively reduced. Of course, the grid of the side wall of the main body frame 1 should not be too large, otherwise the bird cannot be blocked.
Further, the opening areas of the upper end and the lower end of the main body frame 1 are both a, the area of the closing plate is b, and a and b satisfy the following conditions: a/b is more than or equal to 0.2 and less than or equal to 0.7, if a/b is less than 0.2, birds still can enter the main body frame 1 from a gap between the end part of the main body frame 1 and the closing plate, and the closing plate cannot play a role of closing and preventing the birds for the port of the main body frame 1; if a/b is greater than 0.7, the area of the closing plate occupied by the main frame 1 is large, the weight of the main frame 1 is increased, and the material of the closing plate is wasted, which is not practical.

Specifically, the centers of 3 plate blocks 2 are fixedly connected together in a rotatable mode, and the gap between two adjacent plate blocks 2 is adjusted according to the size and the placement position of the main body frame 1, namely, the two adjacent plate blocks 2 can be changed by rotating along the arrow direction, so that the reinforcing and sealing effects of the sealing plate on the main body frame 1 are ensured. The number of the plates 2 may be determined according to practical situations and is not limited to the cases listed in the above embodiments.
Specifically, mounting hole 5 has been seted up at the center of plate 2, and the center of a plurality of plates 2 is overlapped the back, passes mounting hole 5 of a plurality of plates 2 with bolt 6 in proper order to use the nut to fix bolt 6, wherein the nut has arc clearance between rather than adjacent plate 2, makes many plates 2 can encircle its center and rotate, in order to carry out the regulation of 2 extending direction of plate and angle. In this embodiment, both ends of the plate 2 are provided with through holes 4, and the rope can pass through the grid openings and the through holes 4 on the side walls of the main body frame 1 to realize the fixation between the plate 2 and the main body frame 1, and in this embodiment, the material of the rope is the same as that of the 304 stainless steel tie 7 used at the joint of the two sides of the panel-shaped plate-shaped structure. The fixing structure is simple and easy to operate, and the special structure of the existing device is fully utilized.
The even many insulating support bars 3 that are provided with in main body frame 1's lateral wall interval, insulating support bar 3 can play the reinforced effect of support to main body frame 1, but also strengthens main body frame 1's insulating properties. And the included angle alpha between the insulating support bar 3 and the central axis of the main body frame 1 satisfies the following conditions: alpha is more than or equal to 0 and less than or equal to 45 degrees. If α > 45 °, the supporting and reinforcing function of the insulating support bars 3 to the main body frame 1 is weakened, and the reinforcing function of the insulating support bars 3 cannot be exerted. In this embodiment, the contained angle α of insulating support bar 3 and main body frame 1 axis is 0 °, and the length of insulating support bar 3 is the same with main body frame 1's length simultaneously, has fully increased its support reinforcing effect to main body frame 1, and in addition, the even three through-hole of having seted up in interval on the insulating support bar 3 to fix insulating support bar 3 on main body frame 1's lateral wall through ribbon 7. The bird nest prevention device can also be fixedly arranged on a tower through a binding belt 7 (the size and the length of the binding belt can be adjusted). Of course, the fixing of the main frame 1, the closing plates and the fixing of the insulating support bars 3 to the main frame 1 are not limited to the embodiments, and the fixing and connecting methods commonly used in the art are applicable.
In this embodiment, the plate 2 and the insulating support bar 3 forming the sealing plate are made of the same material, that is, cut by using an epoxy resin plate. Meanwhile, the main body frame 1 is made of an outer sleeve layer and a core layer, the core layer is a low-carbon cold-drawn steel wire, the corrosion resistance and the heat resistance are high, the quality is reliable and stable, and the surface of the low-carbon cold-drawn steel wire is coated with a layer of PVC resin by adopting a PVC resin plastic-dipping process, so that the outer sleeve layer is formed. The PVC resin can play anticorrosive, antirust and protective roles for the low-carbon cold-drawn steel wire, and can also play an insulating role.
