The utility model also relates to an electric power transmission system, which is provided with the insulated electric pole with the bird-repelling function. Background Art
[0002] Utility poles are devices for transmitting electricity. The laying of utility poles forms a circuit, which is an indispensable part of power transmission. However, utility poles are mostly installed in farmland, hills and mountains of a certain height. Due to various reasons, utility poles need to be frequently maintained and inspected during use. According to feedback from maintenance personnel, due to defects in the top structure of utility poles, most birds will set up nesting sites on the top of utility poles, such as the cross arm at the top of utility poles, or the top of the utility pole body. However, when birds stay or nest on utility poles, their feces and urine are not insulators. As bird droppings accumulate on insulating cross arms or insulators, they have an adverse effect on the insulation performance of insulating cross arms or insulators, which can easily cause flashover, tripping and other accidents, posing serious safety hazards. In addition, the nests built by birds on the top of utility poles are basically composed of weeds and branches, which can easily catch fire due to short circuits of wires, causing serious damage to the utility pole body (especially fiberglass utility poles). In response to the above problems, some manufacturers have installed related structures on the top of the utility poles that can cover the crossarms and the utility pole body from the top, but such structures cannot actively drive away birds and are in urgent need of improvement.

[0027] 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 in conjunction with 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 used to limit the present invention.
[0028] Please also read Figures 1 to 4 , the insulated electric pole with bird-repelling function provided by the utility model is now described. The insulated electric pole with bird-repelling function comprises an electric pole body 1 and a bird-repelling assembly 2 arranged on the top of the electric pole body 1, wherein the bird-repelling assembly 2 comprises a bell body 21, a hammer 22 and a relay 23, the bell body 21 is bowl-shaped with the concave surface facing downward, the bell body 21 is coaxially buckled on the top of the electric pole body 1, the diameter of the bell body 21 is larger than the top diameter of the electric pole body 1, the hammer 22 is arranged on one side of the bell body 21, and comprises a hammer handle 221 and a hammer head 222, the hammer head 222 is used to hammer the bell body 21, and the hammer handle 221 is a ferromagnetic elastic metal component, one end of the hammer handle 221 is connected to the electric pole body 1, and the other end is integrally connected to the hammer head 222, the relay 23 is arranged on the electric pole body 1, and the relay 23 drives the hammer handle 221 to approach or move away under the action of electromagnetic force.
[0029] In the specific implementation process of this embodiment, the relay 23 is conductively connected to the wire installed on the top of the pole body 1, and because the conductors installed on most poles are alternating current, under the action of alternating current, the relay 23 drives the hammer 22 to strike the bell body 21 to drive away birds.
[0030] Compared with the prior art, the beneficial effect of this embodiment is that the concave surface of the bell body 21 at the top of the utility pole in this embodiment faces downward, which can not only prevent external foreign objects from falling into the cylindrical utility pole body 1, but also prevent birds from building nests on the top of the utility pole body 1, so as to solve the technical problem that birds easily build nests on the top of the existing utility pole body 1; in addition, under the action of the relay 23, the sound emitted by the struck bell body 21 propagates over a long distance, and can also have a bird-repelling effect on the wires near the utility pole body 1.
[0031] Optionally, in order to facilitate closing the relay 23 , a switch is provided in the power circuit of the relay 23 , and the switch is provided at the bottom of the pole body 1 .
[0032] Considering that some transmission lines installed on electric poles are direct current, in some embodiments, Figure 4 As shown, the bird-repelling assembly 2 also includes a conductive protrusion 27 connected in series in the power circuit of the relay 23. The conductive protrusion 27 and the relay 23 are arranged on opposite sides of the hammer handle 221. The end of the hammer handle 221 away from the hammer head 222 is conductively connected to the relay 23. The hammer handle 221 has a first state and a second state. In the first state, the hammer handle 221 abuts against the conductive protrusion 27, and the power circuit is turned on. In the second state, the hammer handle 221 is away from the conductive protrusion 27, and the power circuit is disconnected. In this embodiment, after the relay 23 is powered on, the hammer handle 221 is attracted to approach, and the hammer 22 strikes the bell body 21. After the hammer handle 221 approaches the relay 23, it moves away from the conductive protrusion 27, thereby disconnecting the power circuit of the relay 23. The relay 23 loses its magnetism, causing the hammer handle 221 to move away from the relay 23 under its own elasticity, and the power circuit is turned on. The above process is repeated to continuously strike the bell body 21. Based on the above embodiment, in order to prevent birds from building nests at the location of the relay 23 , a cross arm 11 is provided on the top of the utility pole body 1 , and the relay 23 is located below the cross arm 11 .
[0033] In a possible implementation, the bird repellent assembly 2 further includes a protective shell for accommodating the relay 23, which is installed on one side of the pole body 1 and is located below the cross arm 11. In this way, the protective shell can prevent the relay 23 from being eroded by rain and snow, so that the relay 23 can function stably and effectively for a long time.
[0034] Taking into account that most electric poles are installed in areas far away from the crowd, it is extremely inconvenient to control the switch of the bird-repellent component 2. To address this problem, in a preferred embodiment, the opening and closing of the bird-repellent component 2 is set to be automatic. In detail, the bird-repellent component 2 in the above embodiment also includes a microswitch 24 and a pressure plate 25. The pressure plate 25 is arranged above the crossarm 11, and the length direction of the pressure plate 25 is parallel to the length direction of the crossarm 11. The microswitch 24 is conductively connected to the relay 23 and is arranged on the top of the crossarm 11, and the contacts of the microswitch 24 are in contact with the bottom surface of the pressure plate 25.
[0035] With such arrangement, when the bird is on the pressure plate 25, the pressure plate 25 presses the micro switch 24, at which time the power circuit of the relay 23 is connected, and the hammer 22 strikes the bell body 21 under the action of the relay 23, so as to achieve the technical effect of driving the bird away.
[0036] Preferably, for the multiple cross arms 11 provided on some electric poles, a pressure plate 25 in the above embodiment is provided on each cross arm 11, and the micro switches 24 provided on different cross arms 11 can form an electrical circuit with the relay 23, so that the birds resting on different cross arms 11 can trigger the relay 23 to operate.
[0037] In some embodiments, a plurality of micro switches 24 are connected in series in the power circuit of the relay 23, and each micro switch 24 is evenly spaced between the cross arm 11 and the pressure plate 25 along the length direction of the cross arm 11. Compared with the prior art, the plurality of micro switches 24 arranged on the cross arm 11 in this embodiment can sense whether there are birds staying at different parts of the pressure plate 25, thereby improving the sensitivity of detecting the bird residence situation.
[0038] In some embodiments, the bird-repelling assembly 2 further includes a first hinge shaft 26, the pressure plate 25 is hinged to the pole body 1 through the first hinge shaft 26, and the axial direction of the first hinge shaft 26 is perpendicular to the length direction and the up-down direction of the cross arm 11; the micro switch 24 is located at the cross arm 11 near the first hinge shaft 26. In the specific implementation process of this embodiment, when the birds hide on the pressure plate 25, each unknown number can trigger the micro switch 24, and then trigger the hammer 22 to hammer the bell body 21, so as to achieve the technical effect of driving the birds away.
[0039] Based on the above embodiment, in order to prevent the pressing plate 25 from frequently triggering the micro switch 24 due to external factors, a support spring is further provided between the pressing plate 25 and the cross arm 11 to increase the pressing threshold of the micro switch 24 .
[0040] Preferably, the pole body 1 is a cylinder, and the relay 23 is arranged inside the pole body 1. In this embodiment, the relay 23 is arranged inside the pole body 1, and will not be corroded by rain and snow from the outside, and the relay 23 integrated in the pole body 1 can also make the overall structure of the utility model more integrated and beautiful.
[0041] In summary, the bell body 21 disposed on the top of the electric pole in the utility model can solve the technical problem that birds easily build nests on the top of the existing electric pole body 1; under the action of the relay 23, the utility model can also knock the bell body 21 by swinging the hammer 22, thereby actively driving away the birds that stay on the electric pole or on the top of the electric pole, and preventing the birds from excreting feces while staying on the top of the electric pole, which may adversely affect the performance of the cross arm 11 or the insulator. In addition, the utility model can detect in real time whether the birds have landed on the cross arm 11 and actively drive the birds away by means of the pressure plate 25 and the micro switch 24 disposed on the cross arm 11.
[0042] Based on the same inventive concept, the utility model also proposes a power transmission system, which includes the above-mentioned insulated electric pole with bird-repelling function.
[0043] Compared with the prior art, the power transmission system in the present invention has all the advantages of the above-mentioned insulated utility poles with bird-repelling function, which will not be described in detail here.
[0044] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
