Description

Technical Field

[0001] The utility model relates to the technical field of insulators, in particular to a porcelain insulator with a wire protection structure. Background Technique

[0002] An insulator is a device installed between conductors at different potentials or between a conductor and a grounding member, which can withstand voltage and mechanical stress. There are many types of insulators with various shapes. Although the structures and outer shapes of different types of insulators vary greatly, they are all composed of two major parts: an insulating part and a connecting fitting. Insulators should not fail due to various mechanical and electrical stresses caused by changes in environmental and electrical load conditions. Otherwise, the insulators will not play a significant role and will damage the service life of the entire line.

[0003] According to a disclosed insulator with a wire protection structure (Publication No.: CN220651744U), in the above application, during the screw-threading process, the pressing block abuts against the upper cover to complete the fixation of the entire device. The two cushion blocks are fixed outside the cable through a cable tie, avoiding direct contact between the cable and the insulator body, playing a buffering role and reducing cable wear.

[0004] However, in the actual use process of the above device, only two gaskets are used to protect the cable. When encountering strong wind weather, the strong wind blows the insulator, and the cable and the insulator still generate a large amount of friction, causing cable wear and reducing the service life of the cable. In view of this, we have proposed a porcelain insulator with a wire protection structure. Content of the Utility Model

[0005] The purpose of the utility model is to provide a porcelain insulator with a wire protection structure to solve the problems raised in the above background technique.

[0006] To achieve the above purpose, the utility model provides the following technical solution: A porcelain insulator with a wire protection structure, including a wire, the wire penetrates and is fixedly connected to a housing, a lower clamping plate is fixedly connected to the inner wall of the housing, an upper clamping plate is slidably connected to the inner wall of the housing, a bolt is rotatably connected to the upper end of the upper clamping plate, an insulator group is fixedly connected to the lower end of the housing, and a wire protection assembly is arranged inside the housing. The wire protection assembly includes:

[0007] A rotating shaft, the rotating shaft is fixedly connected to the outer wall of the housing, a connecting frame is rotatably connected to the arc-shaped outer surface of the rotating shaft, a roller is rotatably connected to the inner wall of the connecting frame, and a connecting plate is fixedly connected to the inside of the connecting frame;

[0008] The articulated plate is articulated on the outer wall of the connecting plate. One end of the articulated plate away from the connecting plate is articulated with a slider. A limiting plate is fixedly connected to the outer wall of the slider. A spring is fixedly connected to the outer wall of the slider. A chute is provided on the outer wall of the housing.

[0009] A wind-weakening component is arranged outside the insulator group. The wind-weakening component includes a connecting disc. The connecting disc is fixedly connected to the lower end of the housing. A pulling rope is fixedly connected to the lower end of the connecting disc. One end of the pulling rope away from the connecting disc is fixedly connected to an inner cylinder. The outer arc surface of the inner cylinder is rotatably connected to an outer cylinder. A fan blade is fixedly connected to the outer wall of the outer cylinder.

[0010] Preferably, there is a gap between the inner wall of the inner cylinder and the insulator group. When the wind blows towards the insulator group, only the inner cylinder swings, but it will not affect the insulator group. And a rubber pad is laid on the inner wall of the inner cylinder.

[0011] Preferably, the roller is in contact with the wire. A limiting block is arranged on the outer wall of the limiting plate, and the limiting block is in contact with the articulated plate, so that the articulated plate cannot rotate upwards. When the connecting frame rotates, the slider is pushed to move in the chute.

[0012] Preferably, a through opening is provided on the outer wall of the housing. The number of the wire protection components is four groups. The four groups of wire protection components are distributed in a circumferential array on the outer wall of the opening, so that there are wire protection components around the wire.

[0013] Preferably, the bolt penetrates through the upper outer wall of the housing and is threadedly connected to the upper outer wall of the housing. The lower clamping plate and the upper clamping plate are both provided with arc grooves. The radius of the arc grooves is the same as the radius of the wire. When the bolt drives the upper clamping plate to press down, it can just clamp the wire with the lower clamping plate.

[0014] Preferably, the slider is slidably connected to the inner wall of the chute. One end of the spring away from the slider is fixedly connected to the inner wall of the chute, so that the roller is in closer contact with the wire. After the rotation of the connecting frame ends due to strong wind, the connecting frame is reset.

[0015] Compared with the prior art, the utility model provides a porcelain insulator with a wire protection structure, and has the following beneficial effects:

[0016] 1. For the porcelain insulator with the wire protection structure, through the roller, when the insulator is blown by strong wind, the wire contacts the roller. Since the friction between the wire and the roller is small, the wear of the wire is small. When the wind is too strong, the wire presses the roller to make the connecting frame rotate, so that the slider slides in the chute, so that the wire maintains a state with a small fold angle, so as to maintain a state with a small friction, and prevent the service life of the wire from decreasing due to friction.

[0017] 2. For the porcelain insulator with a wire protection structure, when the wind blows towards the insulator group, the wind will first blow the inner cylinder and the outer cylinder through the pull rope. At this time, the outer cylinder rotates under the influence of the wind, weakening the influence of the wind. At the same time, the inner cylinder also swings. When the insulator group is blown by the wind, the influence of the wind on the insulator group is weakened, making it difficult for the insulator group to be driven by the wind to swing the outer shell, making it difficult for the wire to bend, and protecting the service life of the wire.

[0023] As Figures 1 - 4 shown, the present invention provides a technical solution: a porcelain insulator with a wire protection structure, including a wire 1, the wire 1 penetrates and is fixedly connected to an outer shell 2, a lower clamping plate 3 is fixedly connected to the inner wall of the outer shell 2, an upper clamping plate 4 is slidably connected to the inner wall of the outer shell 2, a bolt 5 is rotatably connected to the upper end of the upper clamping plate 4, an insulator group 6 is fixedly connected to the lower end of the outer shell 2, a wire protection component 7 is arranged inside the outer shell 2, and the wire protection component 7 includes a rotating shaft 71, a connecting frame 72, a roller 73, a connecting plate 74, a hinge plate 75, a slide block 76, a limiting plate 77, a spring 78, and a chute 79.

[0024] In an embodiment of the present invention, the rotating shaft 71 is fixedly connected to the outer wall of the outer shell 2, a connecting frame 72 is rotatably connected to the arc-shaped outer surface of the rotating shaft 71, a roller 73 is rotatably connected to the inner wall of the connecting frame 72, and a connecting plate 74 is fixedly connected to the inside of the connecting frame 72.

[0025] In an embodiment of the present utility model, the hinge plate 75 is hinged to the outer wall of the connecting plate 74. One end of the hinge plate 75 away from the connecting plate 74 is hinged with a slider 76. A limiting plate 77 is fixedly connected to the outer wall of the slider 76. A spring 78 is fixedly connected to the outer wall of the slider 76. A chute 79 is provided on the outer wall of the housing 2.

[0026] In an embodiment of the present utility model, a wind buffering component 8 is arranged outside the insulator group 6. The wind buffering component 8 includes a connecting disk 81. The connecting disk 81 is fixedly connected to the lower end of the housing 2. A pull rope 82 is fixedly connected to the lower end of the connecting disk 81. One end of the pull rope 82 away from the connecting disk 81 is fixedly connected to an inner cylinder 83. The outer arc surface of the inner cylinder 83 is rotatably connected to an outer cylinder 84. A fan blade 85 is fixedly connected to the outer wall of the outer cylinder 84.

[0027] In addition, there is a gap between the inner wall of the inner cylinder 83 and the insulator group 6. When the wind blows towards the insulator group 6, only the inner cylinder 83 swings, but it will not affect the insulator group 6. And a rubber pad is laid on the inner wall of the inner cylinder 83. When the wind force on the insulator group 6 is too strong and the inner cylinder 83 contacts the insulator, the force received by the insulator group 6 is weakened.

[0028] In an embodiment of the present utility model, the roller 73 is in contact with the wire 1. A limiting block is arranged on the outer wall of the limiting plate 77, and the limiting block contacts the hinge plate 75, so that the hinge plate 75 cannot rotate upwards. When the connecting frame 72 rotates, it pushes the slider 76 to move in the chute 79, and the spring 78 deforms to generate a thrust on the slider 76, so as to press the roller 73 against the wire 1.

[0029] In an embodiment of the present utility model, a through opening is provided on the outer wall of the housing 2. The number of the wire protection components 7 is set to four groups. The four groups of wire protection components 7 are distributed in a circumferential array on the outer wall of the opening, so that there are wire protection components 7 around the wire 1, and the wire 1 can be protected when the wind blows from all directions.

[0030] In an embodiment of the present utility model, the bolt 5 penetrates through the upper outer wall of the housing 2 and is threadedly connected to the upper outer wall of the housing 2. Both the lower clamping plate 3 and the upper clamping plate 4 are provided with arc grooves, and the radius of the arc grooves is the same as the radius of the wire 1. When the bolt 5 drives the upper clamping plate 4 to press down, it can just clamp the wire 1 with the lower clamping plate 3, so that the wire 1 can be fixed in the insulator.

[0031] In an embodiment of the present utility model, the slider 76 is slidably connected to the inner wall of the chute 79. One end of the spring 78 away from the slider 76 is fixedly connected to the inner wall of the chute 79, so that the roller 73 fits more closely with the wire 1. After the rotation of the connecting frame 72 ends due to strong wind, the connecting frame 72 is reset, so that the insulator can protect the wire 1 when the wind with different wind forces blows.

[0032] In the present utility model, during use, first place the wire 1 into the lower clamping plate 3, and then rotate the bolt 5 to move the upper clamping plate 4 downward to fix the wire 1. When the insulator swings under strong wind blowing, causing the wire 1 to bend, the wire 1 contacts the roller 73. Due to the small frictional force between the wire 1 and the roller 73, the wear on the wire 1 is reduced. When the wind force is too strong, the wire 1 presses the connecting frame 72 to rotate around the rotating shaft 71. At the same time, the slider 76 slides in the chute 79 and compresses the spring 78. The deformation of the spring 78 generates a thrust force, making the roller 73 fit more tightly with the wire 1. When the wind stops blowing, the connecting frame 72 is reset, so that when the wire 1 bends, it still maintains a small bending angle, thereby keeping the wire 1 always subject to a small frictional force and protecting the service life of the wire 1. When the wind blows towards the insulator group 6, the inner cylinder 83 swings while the outer cylinder 84 rotates, weakening the influence of the wind force on the insulator group 6, making it less likely for the insulator group 6 to be affected by the wind force and causing the entire insulator to swing, resulting in the bending of the wire 1, and protecting the service life of the wire 1.

[0033] The above text has generally described the present utility model in detail. However, based on the present utility model, some modifications or improvements can be made, which are obvious to those of ordinary skill in the technical field. Therefore, modifications or improvements made without departing from the spirit and concept of the present utility model are all within the protection scope of the present utility model.
