Description

Technical Field

[0001] This invention relates to the field of auxiliary protective equipment for electrical insulation devices, and in particular to an insulator protective cover. Background Technology

[0002] During the operation and maintenance of power lines, it is common to encounter various problems caused by bird damage that lead to line tripping, especially for 35kV and above transmission lines in Qinghai Province. Bird-related tripping problems occur frequently, specifically in the following ways: First, when birds perch on the crossarms of towers, if there is an insulator string below, the sparse and stringy bird droppings can flow freely down the edge of the insulator string, causing an instantaneous insulation breakdown and resulting in line tripping. Another type is when birds build nests on the crossarms of towers or other flat areas. During take-off and landing, large birds may spread their wings too long and touch two phase conductors of the line, causing a phase-to-phase short circuit and resulting in line tripping.

[0003] To address these issues, bird-repelling devices such as bird-proofing boards, bird spikes, bird nets, and bird deterrents have been installed on subsequent power line towers to prevent line tripping caused by birds perching on the towers. However, the actual effect has been minimal. Firstly, the currently installed bird-proofing boards, bird spikes, and bird nets are mostly installed on both sides of the crossarms of the power line towers, presenting a significant challenge in transportation. Most towers in Qinghai are located in mountainous and hilly areas, requiring maintenance personnel to carry them to the base of the tower before hoisting them to the top for installation. Secondly, these devices not only harm birds that inhabit the towers but also pose serious safety risks to subsequent transmission line maintenance personnel performing tower-based work. Maintenance workers cannot effectively stand and safely land on the crossarms, further increasing the safety risk during the replacement of insulators, vibration dampers, and drain wires, creating serious safety hazards.

[0004] In addition, although there are relevant patents for insulator protection devices, such as the rigid suspension insulator protective cover described in CN203706751U, which consists of two semi-circular bodies connected by fasteners to form a disc-shaped object, set on the upper part of the insulator, and has a certain slope and a drainage groove set on the upper part of the disc-shaped object for drainage and other stains, it does not have the function of preventing bird damage; another example is the insulator umbrella cover described in CN201886844U, which sets the cover body at the ball head hanging ring at the upper end of the insulator, and sets multiple reflective balls at intervals on the upper part of the cover body for bird deterrence, but its overall bird deterrence effect is not good. Summary of the Invention

[0005] This invention addresses the related problems caused by the deficiencies in the prior art by providing an insulator protective cover, which is installed on the insulator to provide good protection.

[0006] The technical solution adopted in this invention is as follows: An insulator protective cover includes a left disc 1 and a right disc 2, which are interlocked to form an umbrella-shaped disc at the top and are fixedly positioned at the top axis of an insulator string 4. Each of the left and right discs 1 and 2 has a half-hole at its center, forming a single through-hole after interlocking. A pair of semi-slide rails 6 are arranged within this through-hole to form a slide rail. Each semi-slide rail 6 is a stepped, semi-circular truncated cone with a half-hole at its center. The lower circular surface of the semi-slide rail 6 has a semi-circular track, and the upper circular side is also a track. The left and right discs 1 and 2 are outer rings with hollow circular holes. Three evenly spaced openings are formed on the outer edge of the umbrella-shaped disc ring formed by the interlocking disc. A pair of disc blades 9 are fixed to the surface of each opening. The umbrella-shaped disc has a rolled-hole sound tube 13 inside its outer ring; it also includes a reflector 3, which is fixed to the inner wall of the open opening between a pair of disc blades 9; it also includes a bushing 5, which is a cylinder with a side opening, and its inner side wall is sleeved and fixed to the surface of the top shaft of the insulator string 4; it also includes a clamp 7, which clamps a pair of half slide rails 6 with bolts 8; the outer side wall of the slide rail formed by the combination of the pair of half slide rails 6 is located at the position of the inner side wall of the through hole of the umbrella-shaped disc formed by the left disc 1 and the right disc 2 after being fastened together; the bottom surface of the umbrella-shaped disc has a number of ball bearing holes, and is slidably connected to the slide rail through a number of balls 11; at the same time, the side wall of the through hole of the umbrella-shaped disc has a number of needle grooves, and is slidably connected to the outer side wall of the slide rail through a number of needles 12.

[0007] Furthermore, the rotary acoustic tube 13 is formed by connecting the first half tube 131 and the second half tube 132. Its shaft has a hollow square hole, and several rotary blades 133 are arranged at both ends of the square hole. A pair of acoustic strings 134 are arranged between adjacent rotary blades 133.

[0008] Furthermore, the reflector 3 is a prism type.

[0009] Furthermore, the mating surfaces of the left disk 1 and the right disk 2 are mutually matching "S" shapes.

[0010] Furthermore, the upper umbrella-shaped surfaces of the left disk 1 and the right disk 2 are provided with a plurality of water-flow grooves 10 radiating along the center.

[0011] Furthermore, the mating surfaces of the left disc 1 and the right disc 2 are provided with a mutually cooperating buckle seat 14 and a buckle 15; the buckle seat 14 is a "T"-shaped square hole, one end of which is an open square hole and the other end is a semi-open square hole; the buckle 15 is a "T"-shaped buckle body, which is inserted into the open square hole and then slid to the position of the semi-open square hole, so that the left disc 1 and the right disc 2 can be securely fixed.

[0012] Furthermore, another way in which the left disc 1 and the right disc 2 are interlocked is that the lower surfaces of the left disc 1 and the right disc 2 are provided with connecting hinges. Before installation, the two are folded in half, and after installation, they are connected by the hinges.

[0013] Furthermore, the left disk 1 and the right disk 2 are made of insulator composite material.

[0014] Furthermore, bushing 5 is made of insulating rubber.

[0015] Preferably, the acoustic string 134 is positioned at a 45° angle to its fixing surface.

[0016] The beneficial effects of implementing this invention are as follows: This invention allows for convenient and quick installation by maintenance personnel at the top of the insulator string. The insulator cover features an umbrella-shaped disc structure that prevents water and dirt accumulation, while also reducing bird droppings. The cover rotates freely in the wind via disc blades 9, and the structure of the bushing 5, slide rail, ball bearings 11, and needle rollers 12 ensures smooth rotation, preventing birds from alighting. The rotating sound tube 13 and reflector 3 further enhance the bird-repelling effect by creating light and sound during rotation.

[0017] Furthermore, the "S"-shaped mating surface provided by this invention offers flexibility in avoiding obstructions during loading and unloading; the drainage grooves on the umbrella-shaped surface facilitate the removal of accumulated water and bird droppings through gravity during rotation, maintaining surface cleanliness and increasing reliability in preventing slippage during carrying and disassembly; the design of the "T"-shaped buckle seat 14 and buckle 15 makes installation simple and secure, facilitating on-site operation by maintenance personnel; simultaneously, the alternative hinge connection method adopted by this invention also makes installation simple and secure, facilitating on-site operation by maintenance personnel.

[0018] The implementation of this invention can not only solve the problem of insulator string breakdown caused by bird droppings, but also drive away birds that nest and roost at various poles and towers in a non-electric mode using light and sound without harming them. This type of bird-proof device is applicable to areas with severe bird damage along power transmission and distribution lines of different levels. The power-driven mode is environmentally friendly and can greatly solve the problem of repeated bird damage along power lines. Attached Figure Description

Detailed Implementation

[0021] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0022] In one embodiment of the present invention, please refer to the appendix. Figure 1-9 As shown.

[0023] An insulator protective cover includes a left disc 1 and a right disc 2, which are interlocked to form an umbrella-shaped disc at the top and are fixedly positioned at the top axis of the insulator string 4. Each of the left and right discs 1 and 2 has a half-hole at its center, forming a single through-hole after interlocking. A pair of semi-slide rails 6 are arranged within this through-hole to form a slide rail. Each semi-slide rail 6 is a stepped, semi-circular truncated cone with a half-hole at its center. The lower circular surface of the semi-slide rail 6 has a semi-circular track, and the upper circular side also has a track. The interlocking structure facilitates installation and disassembly by maintenance personnel and is easy to carry and transport. The left disc 1 and right disc 2 are outer rings with hollow circular holes. Three evenly spaced openings are formed on the outer edge of the umbrella-shaped outer ring formed by their interlocking. A pair of disc blades 9 are fixed to the surface of each opening. A rolled-hole sound tube 13 is installed inside the outer ring of the umbrella-shaped disc between two openings. A reflector 3 is fixed to the inner wall of the opening between the pair of disc blades 9. The disc blades 9 are driven to rotate by natural wind. During rotation, the reflector 3 reflects natural light to form a disturbing light column. The rolled-hole sound tube 13 generates sound through natural wind. The effects of rotation, reflection, and sound are used to scare away birds.

[0024] The bushing 5 is a cylinder with an opening on the side. Its inner wall is fitted and fixed to the surface of the top shaft of the insulator string 4. The bushing 5 is made of insulating rubber, which forms a good anti-slip surface after it is fixed and tightened, thus avoiding relative displacement between the bushing 5 and the top shaft of the insulator string 4. The bushing 5 is set inside the inner wall of the slide rail formed by the combination of a pair of half slide rails 6, and there is no relative displacement between the two.

[0025] The clamp 7 secures a pair of half slide rails 6 with bolts 8. The outer wall of the slide rail formed by the combination of the pair of half slide rails 6 is located at the inner wall of the through hole of the umbrella-shaped disc formed after the left disc 1 and the right disc 2 are fastened together. The bottom surface of the umbrella-shaped disc has several ball bearing holes, and several balls 11 are slidably connected to the slide rail through the slide rail tracks. At the same time, several needle roller grooves are formed on the side wall of the through hole of the umbrella-shaped disc, and several needle rollers 12 are slidably connected to the outer wall of the slide rail through the track tracks. This structure allows the umbrella-shaped disc to rotate freely, and the balls 11 and needle rollers 12 have good sliding performance, thus allowing the umbrella-shaped disc to rotate freely.

[0026] The insulator cover has an umbrella-shaped disc structure that prevents water and dirt accumulation, while also reducing the adhesion of bird droppings. The insulator cover rotates under the action of natural wind through the disc blades 9. The structure of the bushing 5, slide rail, ball bearings 11, and needle rollers 12 allows the insulator cover to rotate freely, making it impossible for birds to land. The rolled-hole sound tube 13 and reflector 3 set in the insulator cover create a light and sound effect under the action of rotation, which has a better bird-repelling effect.

[0027] Preferred embodiments of the insulator protective cover include: Please see the appendix Figure 4-6 As shown: Preferred Example 1: The first half-tube 131 and the second half-tube 132 are connected to form a spiral-shaped sound tube 13, which has a hollow square hole. Several spiral blades 133 are arranged at both ends of the hole, and a pair of sound strings 134 are arranged between adjacent spiral blades 133. Driven by natural wind, the spiral blades 133 rotate, thus creating a complex circulating wind. The sound strings 134, under the influence of this circulating wind, can emit continuous and complex sounds, achieving a better bird-repelling effect. Preferably, the sound strings 134 are set at a 45° angle to their fixed surface, providing better resonance performance.

[0028] Preferred Example 2: The reflector 3 has a prism structure. The prism structure can reflect natural light at different angles, thereby forming multiple intersecting light pillars. Under the condition of making full use of natural light, a better light-repelling bird effect is achieved.

[0029] Preferred Example 3: The mating surfaces of the left disc 1 and the right disc 2 are matched with each other in an "S" shape. Since the "S" shape has the characteristic that the distance between the mating surface and the edge of the disc is variable, it increases the flexibility of avoiding other obstructions during loading and unloading.

[0030] Preferred Example 4: The upper umbrella-shaped surfaces of the left disc 1 and the right disc 2 are provided with a number of drainage channels 10 radiating from the center. The drainage channels 10 can, on the one hand, allow accumulated water and dirt such as bird droppings to fall smoothly onto the umbrella-shaped surface during rotation by gravity, thus keeping it clean. On the other hand, it increases the reliability of the device during carrying and disassembly, thus making it easy for maintenance personnel to operate.

[0031] Preferred Example 5: The mating surfaces of the left disc 1 and the right disc 2 are provided with a mutually cooperating buckle seat 14 and a buckle 15. The buckle seat 14 is a "T"-shaped square hole, one end of which is an open square hole and the other end is a semi-open square hole. The semi-open square hole acts as a stop for the buckle 15, restricting the buckle 15 from coming out. The buckle 15 is a "T"-shaped buckle body. After it is inserted into the open square hole, it slides to the position of the semi-open square hole, so that the left disc 1 and the right disc 2 can be securely fixed.

[0032] Preferred Example 6: The lower surfaces of the left disc 1 and the right disc 2 are provided with connecting hinges. Before installation, the two are folded in half, and after installation, they are connected by the hinges.

[0033] In the above embodiments: the water channel 10 of the present invention refers to a channel on which water accumulated on its surface can flow in a certain direction along its groove; the vortex sound tube 13 of the present invention is a sound tube with a rotating component and a sound-generating component. When the external natural wind passes through, the wind speed drives the rotating component to rotate and converts the natural wind into turbulence. The sound-generating component emits sound under the action of the airflow. Due to the different wind speeds and different turbulence strengths of the natural wind, the sound-generating component can emit many kinds of sounds and form composite sound effects of different degrees by resonating in the sound tube.

[0034] This invention relates to an insulator protective cover, a novel design device designed to effectively solve the problem of bird damage to insulator strings on power transmission and distribution lines. Under static conditions, it effectively prevents insulator string breakdown caused by bird droppings. Under dynamic conditions, it uses light and sound to drive away birds that nest and roost on various power transmission and distribution lines without harming them. This bird-proof device is applicable to areas with severe bird damage along power transmission and distribution lines of different levels, and is particularly suitable for areas in southwestern and northwestern Qinghai Province or other power grid provinces where bird damage is frequent, effectively solving the problems of bird prevention, bird deterrence, and recurring bird damage.

[0035] Adopting a unique left and right double-disc "S"-shaped active overlapping structure design, with an internal "T"-shaped buckle seat and buckle, it flexibly avoids other obstructions, facilitating quick installation and disassembly by high-altitude workers without affecting the original insulator string installation status. The equipment disc installation area does not occupy the crossarm of the tower, angle steel diagonal members, or other high-altitude work areas for maintenance and rest, ensuring that various maintenance personnel have sufficient footholds and safe resting space when performing high-altitude maintenance on the tower, effectively ensuring the safety of high-altitude workers.

[0036] The insulator protective cover is made of a new type of composite material, which has good insulation performance, is lightweight and reliable. The umbrella-shaped surface is set with a certain slope and several drainage grooves radiating from the center. In rainy weather, raindrops fall on the umbrella-shaped surface and flow down without water accumulation. The internal structure of the disc, including bushings, slide rails, ball bearings and needle rollers, allows the insulator protective cover to rotate freely under natural wind. In heavy rain and windy weather, it can effectively wash away bird droppings, dirt, dust and other adhering objects on the disc surface.

[0037] The unique new type of spiral sound tube design, combined with prism-type reflectors, spiral blades built into the first and second half tubes, and sound strings arranged at a 45° angle, relies on the principle of local air fluid vortex and air resonance. In non-electric mode, driven by the external natural wind, the disc rotates to form a powerful composite sound and light bird-repelling effect. The power-driven mode is environmentally friendly.

[0038] Analysis of existing bird-proof devices such as bird-proof cutting boards, bird-proof spikes, and bird nets reveals that, in practice, their effectiveness in preventing and repelling birds is poor. Furthermore, they not only harm birds perched on power poles but also pose serious safety risks to transmission line maintenance personnel conducting tower-based repairs. This new type of insulator protective cover effectively addresses the various potential safety hazards faced by line maintenance personnel during transportation, installation, and replacement. Moreover, its unique device characteristics achieve bird prevention, repelling, and protection, making it truly economical, environmentally friendly, and highly efficient.

[0039] 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 within the protection scope of the present invention.
