Description

Technical Field

[0001] The utility model belongs to the field of power-related equipment, and more specifically, relates to an insulating end cover of an insulating pole. The utility model also relates to an insulating pole provided with the insulating end cover of the insulating pole. Background Art

[0002] Currently, in infrastructure projects such as power and telecommunications line installation, a large number of utility poles and towers are required to lay conductors or communication lines. In terms of material, existing utility poles can be roughly divided into cement poles, steel poles, wooden poles, and fiberglass poles. Among them, wooden poles are gradually being eliminated due to their low overall structural strength and easy corrosion. The most widely used cement poles and steel poles are relatively bulky. These two types of poles are heavy, especially in construction in complex terrain such as mountainous areas and hills. The complex terrain makes it difficult to transport the poles to the designated locations even with a two-wheeled human-powered vehicle. Transporting them is very difficult, and the labor intensity for power workers is very high. In addition, although cement poles are stronger than wooden poles, their structural strength still cannot meet the existing power line laying requirements, and cement poles are prone to breakage during transportation.

[0003] To address the shortcomings of traditional concrete and steel utility poles, existing manufacturers generally use filament winding technology to produce fiberglass poles. Filament winding involves impregnating a continuous fiber roving or tape with a resin adhesive, wrapping it around a core mold or liner designed to fit the product's inner dimensions, and then curing it at room temperature or under heating to create a product of a desired shape.

[0004] However, most utility poles are located in farmland, hills, and mountains of a certain height. For various reasons, utility poles require frequent maintenance and inspection during use. According to feedback from maintenance personnel, due to defects in the top structure of the utility poles, most birds will nest at the top of the utility poles, such as the crossarms at the top of the utility poles, or the top of the utility pole itself. However, when birds stay or nest on the utility poles, their feces and urine are not insulators. As bird droppings accumulate on the insulating crossarms or insulators, they have an adverse effect on the insulation performance of the insulating crossarms or insulators, which can easily cause flashovers, tripping, and other accidents, posing a serious safety hazard. In addition, the nests built by birds on the top of the utility poles are basically composed of weeds and branches, which can easily catch fire due to short circuits in the wires, causing serious damage to the utility pole itself (especially fiberglass poles). To address the above issues, some manufacturers have installed passive protection and active repellent structures on the top of utility poles that can cover the crossarms and the utility pole body from the top. However, such structures cannot actively repel birds, and some bird-repellent components with active repellent functions have relatively complex structures, resulting in excessively high costs and urgent need for improvement. Utility Model Content

[0005] The utility model aims to provide an insulating end cover for an insulating electric pole, so as to solve the technical problem that the existing bird shielding plate on the top of the electric pole cannot actively drive away birds.

[0006] To achieve the above-mentioned purpose, the technical solution adopted by the present invention is: to provide an insulating end cover of an insulating electric pole, comprising an end cover and a bird-repelling assembly, wherein the end cover is arranged at the top of the electric pole, and the bird-repelling assembly comprises a pendulum, a top plate, a bell body and a connecting ball, the pendulum comprises a hammer rod and a hammer head, the connecting ball is arranged at the top of the hammer rod, the hammer head is arranged at the bottom end of the hammer rod, the connecting ball is connected to the middle part of the end cover, the connecting ball sleeve is arranged on the outer periphery of the hammer rod, and the top end of the hammer rod extends out of the end cover; the top plate is arranged at the top end of the hammer rod, and the plate surface of the top plate is perpendicular to the axis of the hammer rod, the bell body is arranged with the concave surface facing downward below the end cover, and the top of the bell body is connected to the end cover; the hammer rod penetrates the bell body in the up and down directions, and the hammer head can knock the inner wall of the bell body as the hammer rod swings.

[0028] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0029] Please also refer to Figure 1 and Figure 2Now, the insulating end cover of the insulating pole provided by the utility model is described. The insulating end cover of the insulating pole includes an end cover and a bird-repelling assembly 2, wherein the end cover is arranged at the top of the pole 3, and the bird-repelling assembly 2 includes a pendulum 21, a top plate 22, a bell body 23 and a connecting ball 24. The pendulum 21 includes a hammer rod 211 and a hammer head 212, the connecting ball 24 is arranged at the top of the hammer rod 211, the hammer head 212 is arranged at the bottom end of the hammer rod 211, the connecting ball 24 is connected to the middle of the end cover, the connecting ball 24 is sleeved on the outer periphery of the hammer rod 211, and the top end of the hammer rod 211 extends out of the end cover; the top plate 22 is arranged at the top of the hammer rod 211, and the plate surface of the top plate 22 is perpendicular to the axis of the hammer rod 211, the bell body 23 is arranged below the end cover with the concave surface facing downward, and the top of the bell body 23 is connected to the end cover, the hammer rod 211 penetrates the bell body 23 in the up and down direction, and the hammer head 212 can knock the inner wall of the bell body 23 as the hammer rod 211 swings.

[0030] Compared with the prior art, in this embodiment, when a bird lands on the top plate 22, the force balance of the top plate 22 is broken, thereby driving the pendulum 21 to swing. The pendulum 21 strikes the inner wall of the bell body 23 during the swinging process, scaring away the flying birds that land on the top plate 22. The utility model has a simple and reliable structure and low cost. While being able to block the opening at the top of the utility pole, it can also actively drive away the birds. In addition, the utility model can widen the swing range of the pendulum 21 through the rotational connection between the connecting ball 24 and the end cover, thereby preventing the technical problem that birds land on the top plate 22 but cannot drive the pendulum 21 to swing. Not only that, the top plate 22 in this embodiment can not only prevent birds from landing on the end cover, but also prevent rain and snow from eroding the connection between the pendulum 21 and the bell body 23, thereby improving the reliability of the bird-repelling component 2 in this embodiment.

[0031] It should be noted that, considering that the birds that build nests on the top of the utility poles are generally small in size, taking the passerines and corvids that are more widely distributed in the plains as an example, the weight of a sparrow is about 50 grams and the weight of a magpie is about 200 grams. Sparrows do not build nests, and the utility model mainly plays a role in driving them away, preventing excessive bird droppings from accumulating on the top of the utility poles. Considering the weight of the birds, the weight of the pendulum 21 should not be too heavy, and is generally set to be about 20 grams heavier than the top plate 22.

[0032] Based on the above embodiment, the inner wall of the bell body 23 is provided with a collision protrusion so that the hammer head 212 can collide with the inner wall of the bell body 23 during the swinging and rotating process. In addition, the arrangement of the inner wall protrusion can also enhance the structural strength of the bell body 23.

[0033] Preferably, in a feasible embodiment, the bird-repelling assembly 2 further includes a plurality of blades 221, each blade 221 being evenly spaced and disposed on the edge of the end cap. Compared to the prior art, this embodiment can utilize airflow to drive the rotation of the top plate 22, thereby preventing birds from landing on the top plate 22 for a long time.

[0034] Based on the above embodiment, there are multiple hammer heads 212, each of which is connected to the bottom end of the hammer rod 211 via a connecting rope 213. In this embodiment, as the pendulum 21 rotates, the hammer heads 212 at the bottom end of the hammer rod 211 move away from the hammer rod 211 under the action of centrifugal force, and then strike the inner wall of the bell body 23. In this way, the bird-repelling assembly 2 of the present invention can continuously emit sound under the influence of airflow to drive away birds that land on the top of the utility pole.

[0035] In some embodiments, the end cap includes an end cap body 1 and a connecting bearing 11. The connecting bearing 11 is disposed in the middle of the end cap body 1, with the axis of the connecting bearing 11 parallel to the vertical direction. The inner surface of the connecting bearing 11 forms a ball connection with the connecting ball 24. Compared to the prior art, the connecting bearing 11 in this embodiment can form a rotational connection between the end cap body 1 and the connecting ball 24, allowing the connecting ball 24 to rotate and swing more smoothly relative to the connecting bearing 11.

[0036] Preferably, in some embodiments, the connecting bearing 11 is made of brass, and lubricating graphite is embedded in the inner surface of the connecting bearing 11, and the connecting ball 24 is slidably adapted to the connecting bearing 11. Compared with providing a rotating bearing, the graphite copper sleeve is more economical to manufacture, and the copper sleeve is also less prone to rust, having better durability and being suitable for a wide range of applications.

[0037] Preferably, in some possible embodiments, a plurality of rolling balls are disposed between the inner surface of the connecting bearing 11 and the connecting balls 24, and the connecting balls 24 are adapted to roll with the connecting bearing 11 via the rolling balls. In this embodiment, the provision of the rolling balls enables a rolling fit between the connecting balls 24 and the connecting bearing 11, preventing the pendulum 21 from getting stuck during its swing. It should be noted that a retaining cage is provided within the connecting bearing 11 to prevent the connecting balls 24 from running around, thereby preventing interference between different connecting balls 24.

[0038] In addition to the above feasible implementation methods, in order to facilitate the installation of the end cap on the top of the electric pole 3, a preferred implementation method is proposed. In detail, the edge of the end cap is provided with a rubber ring 12, which is used to form a sealing fit between the end cap and the electric pole 3, and the material of the rubber ring 12 is hot melt adhesive. In this embodiment, the rubber ring 12 can adhere the end cap to the top of the electric pole to prevent the electric pole 3 and the end cap from loosening. In addition, the rubber ring 12 can be softened by heating the rubber ring 12, making the installation and removal of the end cap on the electric pole 3 more convenient. Based on this embodiment, further, a heating wire is embedded in the rubber ring 12. With this arrangement, the hot melt adhesive can be heated by connecting the heating wire to a power source, making the softening of the hot melt adhesive more convenient and helping to reduce the fire hazard during the installation of the end cap on the electric pole.

[0039] In one possible implementation, the top of the bell body 23 is threadedly adapted to the end cap, making assembly between the bell body 23 and the end cap more portable. Preferably, in this embodiment, since the top plate 22 can protect the end cap from rain and snow erosion, the end cap is provided with multiple through-holes to allow the sound emitted by the bell body 23 inside the pole to be more smoothly transmitted to the outside of the end cap.

[0040] Based on the same inventive concept, the present invention also provides an insulating pole, which includes the insulating end cover of the insulating pole mentioned above.

[0041] Compared with the prior art, the insulating pole in the present invention has all the benefits of the insulating end cover of the above-mentioned insulating pole, which will not be described here.

[0042] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
