Description
Technical Field
[0001] The utility model relates to the technical field of insulators, in particular to a novel insulator for power transmission. Background Art
[0002] Insulators are widely used in power systems. They are generally external insulators that work under atmospheric conditions. Suspension insulators are widely used in transmission lines. They are generally made of insulating parts such as porcelain parts, glass parts and metal accessories such as steel feet, iron caps, flanges, etc. glued together or mechanically clamped.
[0003] At present, the common insulators for power transmission on the market are mostly similar in structure. In actual use, there are some functional deficiencies and room for improvement. For example, the glass parts made of tempered glass are relatively strong in themselves. When replacing them later, power workers need to smash them with hammers on the elevated platform. It is difficult to smash hard glass parts and they need to be hit repeatedly, which consumes a lot of physical energy for power workers. They do not have the function of being easy to smash quickly. Secondly, when power workers walk on the cables, they generally step on the back of the iron cap and move forward with it as the force point. The iron cap with a rounded surface is not easy to bear force when stepped on. Once it slips, it is extremely dangerous. It does not have the function of anti-slip and easy to step on the back. In addition, the common insulators on the market are all made by improving their own materials to prevent birds from pecking, but they cannot prevent birds from staying. Once birds land on the insulators, they are easily pierced by high-voltage arcs. Once birds are stuck between insulators, the insulators are contaminated, the insulation capacity is reduced, and it is troublesome to clean them later. They do not have the function of reflecting the light on the top to drive away birds. Utility Model Content
[0004] The purpose of the utility model is to provide a novel insulator for power transmission to solve the problems raised in the above background technology.
[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:
[0006] A novel insulator for power transmission, comprising an iron cap 1, wherein an embedding groove 2 is provided at the top of the front end of the iron cap 1, a pin hole 3 is provided at the top of the rear end of the iron cap 1 corresponding to the position of the embedding groove 2, a tempered glass piece 4 is fixedly connected to the bottom of the iron cap 1, and a steel foot 5 is fixedly connected to the middle position of the bottom of the iron cap 1, and the steel foot 5 is adapted to the embedding groove 2;
[0007] Both sides of the top of the tempered glass 4 are provided with knocking structures; the knocking structure includes an inverted concave plastic frame 6, and both ends of the bottom of the concave plastic frame 6 are fixedly connected to the inside with adhesive feet 7, and the bottom end of the adhesive foot 7 is adhesively connected to the top of the tempered glass piece 4; a hard quadrangular pyramid 8 is provided in the middle position of the inner top of the concave plastic frame 6, and the bottom end of the hard quadrangular pyramid 8 is higher than the top of the tempered glass piece 4.
[0008] Through the above technical solution, the adhesive feet at the bottom of the concave plastic frame facilitate connection with the surface of the tempered glass piece through the glue, the hard quadrangular pyramid and the tempered glass piece do not contact each other, and the sharp bottom of the quadrangular pyramid can quickly crack the tempered glass piece, so that it breaks into pieces and falls downward, which is convenient for quickly hitting the broken glass piece; it solves the problem that when the existing insulator is replaced later, the power workers need to smash it with a hammer on the elevated platform, the hard glass piece is difficult to smash, the power workers consume a lot of physical strength, and it is not convenient to smash it quickly.
[0009] Furthermore, triangular pyramidal bars 9 are respectively and vertically fixedly arranged on both sides of the rear end of the iron cap 1 . The triangular pyramidal bars 9 are integrally cast with the iron cap 1 , and the triangular pyramidal bars 9 are symmetrically distributed about the vertical center line of the iron cap 1 .
[0010] Through the above technical solution, the triangular pyramidal bar can be supported on the soles of the feet of power workers, which can increase friction, reduce the probability of slipping accidents during the movement of power workers, and improve the safety of workers when moving. Therefore, the setting of the triangular pyramidal bar can increase the friction of the feet, reduce the probability of slipping accidents, and solve the problem that the existing insulators do not have anti-slip on the back, which is not conducive to workers' stepping.
[0011] Furthermore, a plurality of groups of reflective sequins 10 arranged at equal intervals are glued to the rear end of the iron cap 1 .
[0012] Through the above technical solution, when the insulator is installed, the back of the iron cap 1 faces the sky, and the reflective sequins on the back of the iron cap reflect upward under light to form a dazzling light spot effect. Birds flying nearby will be stimulated, reducing the probability of them landing on the insulator, avoiding the staff's subsequent cleaning and reducing their overall work intensity.
[0013] Furthermore, the embedding groove 2 is a "T"-shaped structure to increase firmness.
[0014] Compared with the prior art, the power transmission insulator of the utility model has the following beneficial effects:
[0015] (1) By providing a concave plastic frame, adhesive feet and hard ceramic tetrahedron, when the insulator needs to be replaced, the power worker climbs up the tower and hits the top of the concave plastic frame with a hammer. The concave plastic frame is depressed by the force, and the hard ceramic tetrahedron fixed inside the concave plastic frame presses down to impact the surface of the tempered glass. The sharp bottom of the hard ceramic tetrahedron can quickly crack the tempered glass, causing it to break into pieces and fall downward, thus achieving the function of being easy to quickly crush;
[0016] (2) By providing the iron cap and the triangular pyramid strip, when the electric power workers need to walk on the cable, their feet generally step on the back of the iron cap, and the iron cap is pressed down by force, so that the connection between the embedded groove and the steel foot becomes tighter and will not easily loosen. The triangular pyramid strips on both sides of the top of the iron cap can be supported on the soles of the electric power workers' feet, thereby increasing the friction force, reducing the probability of slipping accidents of the electric power workers during walking, improving the safety of the workers during walking, and realizing the function of anti-skid and easy-to-step on the back;
[0017] (3) By providing a reflective sequin, when the insulator is installed, the back of the iron cap faces the sky. Under the sunlight, the reflective sequin reflects the sunlight upward to form a dazzling light spot effect. Birds flying nearby will be stimulated and quickly fly to the corresponding position, reducing the probability of them landing on the insulator, avoiding the staff from cleaning up later, reducing their overall work intensity, and realizing the function of top reflective bird repellent.
[0018] In summary, the power transmission insulator of the utility model not only realizes the function of being easy to crush quickly and having a non-slip back for easy walking, but also realizes the function of reflecting light on the top to drive away birds, thereby increasing safety performance, reducing work intensity, and saving time and effort.

[0027] Example 1
[0028] like Figure 1 , Figure 4 As shown, this embodiment proposes a new type of insulator for power transmission, including an iron cap 1, the top of the front end of the iron cap 1 is provided with an embedding groove 2, the embedding groove 2 is a "T"-shaped structure, the top of the rear end of the iron cap 1 is provided with a pin hole 3 corresponding to the position of the embedding groove 2, the bottom of the iron cap 1 is fixedly connected with a tempered glass piece 4, and the middle position of the bottom of the iron cap 1 is fixedly connected with a steel foot 5, and the steel foot 5 is adapted to the embedding groove 2. When in use, generally multiple groups of insulators are connected in series, the steel foot at the bottom of the upper insulator is inserted into the embedding groove at the front end of the iron cap of the lower insulator, and then a pin is driven into the pin hole at the rear end of the iron cap to engage the steel foot to prevent it from falling off, and multiple insulators are connected to form an insulating string.
[0029] Both sides of the top of the tempered glass 4 are provided with a knocking structure, and the knocking structure includes an inverted concave plastic frame 6, and both ends of the bottom of the concave plastic frame 6 are fixedly connected to the inside with adhesive feet 7, and the bottom end of the adhesive foot 7 is adhesively connected to the top of the tempered glass piece 4; a hard quadrangular pyramid 8 is provided in the middle position of the inner top of the concave plastic frame 6, and the bottom end of the hard quadrangular pyramid 8 is higher than the top of the tempered glass piece 4.
[0030] During specific implementation, the adhesive feet at the bottom of the concave plastic frame are connected to the surface of the tempered glass piece by glue, so that the concave plastic frame is fixed on the tempered glass. When replacing, the electrician uses a hammer to violently hit the top of the concave plastic frame, and the concave plastic frame is depressed by the force. The hard quadrangular pyramid fixed inside the concave plastic frame presses down to impact the surface of the tempered glass piece. The sharp bottom of the hard quadrangular pyramid can quickly crack the tempered glass piece, causing it to break into pieces and fall downward. The hard quadrangular pyramid and the tempered glass piece do not contact each other, which is convenient for quickly hitting the broken glass piece.
[0031] Example 2
[0032] like Figure 2 , Figure 3 As shown, triangular pyramidal bars 9 are vertically fixedly arranged on both sides of the rear end of the iron cap 1. The materials of the triangular pyramidal bars 9 and the iron cap 1 are consistent, and the two are integrally cast. The triangular pyramidal bars 9 are symmetrically distributed about the vertical center line of the iron cap 1.
[0033] In specific implementation, the triangular pyramidal bars 9 on both sides of the top of the iron cap 1 can be supported on the soles of the feet of the power workers, which can increase the contact surface and increase the friction, reduce the probability of slipping accidents of the power workers during the movement, and improve the safety of the workers during the movement.
[0034] Example 3
[0035] like Figure 3 The rear end of the iron cap 1 is glued with a plurality of reflective sequins 10 arranged at equal intervals.
[0036] In specific implementation, when the insulator is installed, the back of the iron cap faces the sky. The reflective sequins on the back of the iron cap reflect upward under light to form a dazzling light spot effect. Birds flying nearby will be stimulated, reducing the chance of them landing on the insulator, avoiding subsequent cleaning by staff and reducing their overall work intensity.
[0037] Working principle:
[0038] When the utility model is in use, firstly, generally multiple groups of insulators are connected in series with each other, and the steel foot 5 at the bottom of the upper insulator is inserted into the embedding groove 2 at the front end of the iron cap 1 of the lower insulator, and then a pin is driven into the pin hole 3 at the rear end of the iron cap 1 to engage the steel foot 5 to prevent it from falling off. Multiple insulators are connected to form an insulating string, which can connect the wire at a high potential with the pole tower at a low potential, and withstand the mechanical forces such as gravity and wind force of the wire. As the service life of the insulator is approaching, the power staff needs to break it and replace it with a new insulator. After the power worker climbs to the tower, he uses a hammer to violently hit the top of the concave plastic frame 6. The concave plastic frame 6 is depressed by the force, and the hard quadrangular pyramid 8 fixed inside the concave plastic frame 6 presses down to impact the surface of the tempered glass piece 4. The sharp bottom of the hard quadrangular pyramid 8 can quickly crack the tempered glass piece 4, causing it to fall off after being broken into pieces. The adhesive foot 7 at the bottom of the concave plastic frame 6 facilitates its connection with the surface of the tempered glass piece 4 through the glue.
[0039] When the electric power workers need to walk on the cables, their feet usually step on the back of the iron cap 1. The iron cap 1 is pressed down by force, and the connection between the embedded groove 2 and the steel foot 5 becomes tighter and will not be easily loosened. The triangular pyramid strips 9 on both sides of the iron cap 1 can be supported on the soles of the electric power workers, which match the pattern of the soles of the electric power workers' shoes. While increasing the contact surface, the friction can be increased, which reduces the probability of slipping accidents of the electric power workers during the walking process and improves the safety of the workers during the walking process. When the insulator is installed, the back of the iron cap 1 faces the sky. Under the sunlight, the reflective sequins 10 with a mirror surface on the upper surface reflect the sunlight upward, forming a dazzling light spot effect. Birds will be stimulated when flying nearby, and quickly return to the corresponding position, reducing the probability of them landing on the insulator and staying, avoiding the staff's later cleaning and reducing their overall work intensity.
