[0028] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0029] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0030] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.

[0031] Example 1, reference Figures 1 to 9 , which is the first embodiment of the present invention, and this embodiment provides a 35kV transmission line lightning protection and anti-icing integrated insulator. The 35kV transmission line lightning protection and anti-icing integrated insulator includes a main body component 100, including a mounting seat 101, a threaded column 102, a fixing nut 103, a fixed umbrella column 104 and a movable umbrella column 105. The threaded column 102 is fixed to the bottom of the mounting seat 101, the fixing nut 103 is connected to the surface of the threaded column 102 by threaded rotation, the fixed umbrella column 104 is fixed to the top of the mounting seat 101, and the movable umbrella column 105 is arranged above the fixed umbrella column 104.

[0032] The materials used in this device are all insulating materials. The mounting base 101 is used to support the fixed umbrella column 104. The mounting base 101 is fixed on the angle iron through the cooperation of the threaded column 102 and the fixing nut 103. There are two fixing nuts 103, so that the mounting base 101 is fixed more firmly. The movable umbrella column 105 can be close to or away from the fixed umbrella column 104. The fixed umbrella column 104 and the movable umbrella column 105 are both made of insulating ceramics. The top surfaces of the fixed umbrella column 104 and the movable umbrella column 105 are both arc-shaped surfaces, and the angle of the arc surface is 15 degrees. Combined with the smooth surface design, rainwater will not stay on the surfaces of the fixed umbrella column 104 and the movable umbrella column 105, thereby preventing icicles from forming on the surfaces of the fixed umbrella column 104 and the movable umbrella column 105.

[0033] The protective component 200 is arranged in the main body component 100, and includes an insulating column 201a fixed in the movable umbrella column 105, a push rod 201b is slidably connected in the insulating column 201a, a push plate 201c is fixed on the top of the push rod 201b, a top plate 201d is fixed on the top of the push plate 201c, an extrusion ring 201e is fixed on the top of the top plate 201d, a support seat 201f is fixed on the top of the insulating column 201a, a support block 201g is fixed on the top of the insulating column 201a, a rotating clamp 201h is rotatably connected in the support block 201g, a friction plate 201i is fixed on the end of the rotating clamp 201h, and a first spring 201j is fixed on the bottom of the push plate 201c.

[0034] A torsion spring is provided at the connection between the support block 201g and the rotating clamp 201h. Through the reset elastic force of the torsion spring, the two rotating clamps 201h can be moved away from each other when the rotating clamp 201h is not subjected to force. The first spring 201j is in a stretched state. Through the reset tension of the first spring 201j, the first spring 201j can pull the push plate 201c so that the extrusion ring 201e is retracted into the insulating column 201a. When the transmission line is placed on the top of the support seat 201f, the support seat 201f can be pulled against the insulating column 201a and the movable umbrella The column 105 is pressed downward, so that the insulating column 201a and the movable umbrella column 105 move downward. At this time, the push rod 201b pushes the push plate 201c, so that the push plate 201c drives the two top plates 201d to squeeze the squeezing ring 201e, so that the squeezing ring 201e squeezes the two rotating clamps 201h, so that the two rotating clamps 201h drive the two friction plates 201i to move closer to the middle, so as to limit the transmission line, so that the transmission line can still maintain a stable connection with the insulator when subjected to external forces such as wind, ice, etc., and is not easy to deviate or fall off.

[0035] At this time, the two friction plates 201i have not yet contacted the transmission line, so that the transmission line can slide on the top of the support seat 201f. When the transmission line generates heat during operation, causing the line to expand, there will be no excessive tension between the two friction plates 201i when the line expands, which can prevent the line from being damaged.

[0036] At the same time, not clamping and fixing the transmission lines can prevent the transmission lines from being affected by external forces such as wind, ice, and snow in outdoor environments, will not cause excessive pressure on the lines and insulators, avoid metal fatigue in the clamped parts of the lines, and increase or decrease the service life of the lines.

[0037] Specifically, the protection assembly 200 also includes a support member 202, which is arranged in the fixed umbrella column 104, including an insulating rod 202a fixed in the fixed umbrella column 104, a second spring 202b is fixed in the insulating rod 202a, and the other end of the second spring 202b is fixed to the inner wall of the insulating column 201a.

[0038] The second spring 202b is in a compressed state. The second spring 202b is used to support the insulating column 201a. When the transmission line is placed on the top of the insulator, the pressure of the transmission line can make the bottom of the insulating column 201a contact with the top of the insulating rod 202a. A limiting ring is set at the bottom of the insulating column 201a, so that the lifting position of the insulating column 201a is limited and it will not rise too long under the push of the second spring 202b.

[0039] Specifically, the protection assembly 200 further includes a limiter 203, which is disposed in the insulating column 201a and includes a support shaft 203a fixed in the insulating column 201a, and a plug rod 203b is rotatably connected to the surface of the support shaft 203a.

[0040] The support shaft 203a is used to support the insertion rod 203b, so that the insertion rod 203b can rotate arbitrarily on the surface of the support shaft 203a.

[0041] Specifically, a flat groove 201b-1 is formed on the surface of the push rod 201b, a clamping groove 201b-2 is formed on one side of the flat groove 201b-1, the end of the insertion rod 203b is located in the clamping groove 201b-2, and a chamfer 203b-1 is formed on the end of the insertion rod 203b.

[0042] By inserting the end of the rod 203b into the slot 201b-2, the push rod 201b can be limited. When the insulating column 201a moves downward, the chamfer 203b-1 can drive the end of the rod 203b to slide down on the surface of the slot 201b-2. At this time, if the insulating column 201a rises, the push rod 201b can be driven to rise synchronously through the rod 203b.

[0043] Specifically, a push plate 203c is fixed to one side of the insertion rod 203b, a third spring 203d is fixed to the inner wall of the push plate 203c, and the other end of the third spring 203d is fixed to the inner wall of the insulating column 201a.

[0044] The third spring 203d is in a compressed state. The third spring 203d pushes the push plate 203c, so that the push plate 203c pushes the insertion rod 203b, so that the end of the insertion rod 203b is tightly attached to the slot 201b-2.

[0045] Example 2, reference Figures 1 to 9 , which is the second embodiment of the present invention, and this embodiment is based on the previous embodiment.

[0046] Specifically, the protective assembly 200 also includes a reset member 204, which is arranged in the fixed umbrella column 104, including a button 204a that slides in the fixed umbrella column 104, a limiting block 204b is fixed on one side of the button 204a, and an extrusion rod 204c is fixed on one side of the button 204a, and the extrusion rod 204c is located on one side of the push plate 203c.

[0047] By pressing the button 204a, the extrusion rod 204c can be driven to move toward the push plate 203c, so that the push plate 203c drives the insertion rod 203b to rotate, so that the end of the insertion rod 203b is away from the slot 201b-2, thereby releasing the limit on the push rod 201b. The limit block 204b is used to limit the button 204a to prevent the button 204a from moving out of the fixed umbrella column 104. The button 204a and the fixed umbrella column 104 are made of the same material and both have high insulation properties.

[0048] Specifically, a support plate 204d is fixed inside the fixed umbrella column 104, a fourth spring 204e is fixed to one side of the support plate 204d, and the other end of the fourth spring 204e is located at one side of the button 204a.

[0049] The support plate 204d is used to support the fourth spring 204e, and the fourth spring 204e is used to support the button 204a, so that the button 204a can be reset after being pressed.

[0050] Specifically, the protection component 200 also includes a fastener 205, which is arranged in the mounting seat 101, including an extrusion sleeve 205a sliding in the mounting seat 101, a fifth spring 205b is fixed on the top of the extrusion sleeve 205a, and a lifting sleeve 205c is fixed on the top of the fifth spring 205b.

[0051] When the mounting seat 101 is installed on the angle iron, the extrusion sleeve 205a will be squeezed into the mounting seat 101. At this time, the fifth spring 205b will be highly compressed. The fifth spring 205b is a high-strength spring. The compressed fifth spring 205b has a very large elastic force, so that the fifth spring 205b provides a very large thrust for the lifting sleeve 205c.

[0052] Specifically, a lifting plate 205d is fixed in the lifting sleeve 205c, and a push rod 205e is arranged in the lifting plate 205d.

[0053] The lifting sleeve 205c can push the push rod 205e through the lifting plate 205d, so that the push rod 205e moves upward, and the push rod 205e is fixed in the push rod 201b.

[0054] Specifically, a limit strip 205f is slidably connected inside the lifting plate 205d, a limit block 205g is fixed on the top of the limit strip 205f, a sixth spring 205h is fixedly connected between the two limit blocks 205g, a placement groove 205e-1 is provided on the surface of the top rod 205e, a card slot 101-1 is provided in the mounting seat 101, and a monitor 205i is provided on the top wall of the mounting seat 101.

[0055] The sixth spring 205h is in a stretched state. By setting the limit strip 205f, the limit block 205g can stably slide on the top of the lifting plate 205d. At this time, one side of the limit block 205g is clamped in the clamping groove 101-1, so that the lifting plate 205d cannot move relative to the mounting seat 101. When the push rod 201b drives the push rod 205e to rise, the placement groove 205e-1 can be moved to the side of the limit block 205g. At this time, the two limit blocks 205g are close to each other under the pulling force of the sixth spring 205h, so that the two limit blocks 205g move into the placement groove 205e-1. At this time, the limit block 205 g is away from the card slot 101-1, thereby releasing the limit on the lifting plate 205d. At this time, under the thrust of the fifth spring 205b, the lifting plate 205d can drive the top rod 205e to move upward, so that the top rod 205e drives the push rod 201b to move upward, so that the rotating clamp 201h has a greater clamping force, so that the two friction plates 201i are moved closer to the middle, so as to clamp and fix the transmission line. The monitor 205i is a prior art and can be bought on the market. It can monitor the approach of the limit block 205g and send a signal to the base station when the limit block 205g approaches, so as to quickly locate the fault.

[0056] In summary, the present invention has the following beneficial effects:

[0057] 1. When the transmission line is placed on the top of the insulator, the transmission line is limited to ensure that the transmission line can maintain a stable connection with the insulator when subjected to external forces such as wind and ice, and is not prone to deviation or falling off;

[0058] 2. When the transmission line is placed on the top of the insulator, there is a certain distance between the transmission line and the two friction plates 201i. When the transmission line generates heat during operation, causing the line to expand, there will be no excessive tension between the line and the two friction plates 201i during expansion, which can prevent the line from being damaged;

[0059] 3. When the transmission line is placed on the top of the insulator, the transmission line is not clamped and fixed, which can prevent the transmission line from being affected by external forces such as wind, ice, and snow in the outdoor environment, and will not cause excessive pressure on the line and insulator, avoiding metal fatigue in the clamped part of the line, thereby improving the service life of the line;

[0060] 4. When a transmission line break is detected, the remaining line can be quickly clamped and fixed, further preventing the line from falling off and possible safety hazards;

[0061] 5. When clamping the broken transmission line, it can transmit signals to the base station, which improves the accuracy and efficiency of fault location and provides convenience for subsequent maintenance work.

[0062] Example 3, reference Figures 1 to 9 , which is the third embodiment of the present invention, and this embodiment is based on the previous embodiment. This embodiment also provides a method for using a 35kV transmission line lightning protection and ice protection integrated insulator, the method comprising:

[0063] During use, when the insulator is fixed on the angle iron, the fifth spring 205b can be compressed. At this time, the transmission line is placed on the top of the insulator, so that the transmission line presses down on the support seat 201f, so that the insulating column 201a and the movable umbrella column 105 move downward. At this time, the bottom of the insulating column 201a is in contact with the top of the insulating rod 202a. In this process, the downward movement of the insulating column 201a causes the push rod 201b to push the push plate 201c, so that the push plate 201c drives the two top plates 201d to squeeze the extrusion ring 201e, and the extrusion ring 201e squeezes the two rotating clamps 201h, so that the two rotating clamps 201h drive the two friction plates 201i to move closer to the middle, thereby limiting the transmission line.

[0064] When the insulating column 201a moves downward, the chamfer 203b-1 can drive the end of the plug rod 203b to slide down on the surface of the slot 201b-2. When the bottom of the insulating column 201a contacts the top of the insulating rod 202a, the end of the plug rod 203b is inserted into the slot 201b-2 to limit the push rod 201b. If the transmission line is blown by wind at this time, causing the transmission line to swing up and down, the pressure of the transmission line on the insulating column 201a is insufficient. At this time, the insulating column 201a will move upward under the push of the second spring 202b. At this time, the insulating column 201a can drive the push rod 201b to move upward synchronously through the plug rod 203b.

[0065] When the transmission line breaks, the broken part of the transmission line will quickly move to the top of the insulator. At this time, the pressure on the insulator will decrease. Under the push of the second spring 202b, the insulating column 201a and the push rod 201b move upward to the maximum distance. During this process, the push rod 201b can drive the top rod 205e to move upward, so that the placement groove 205e-1 moves to the side of the limit block 205g. At this time, the two limit blocks 205g are close to each other under the pulling force of the sixth spring 205h, so that the two limit blocks 205g move. Into the placement slot 205e-1, the limit block 205g is now away from the card slot 101-1, thereby releasing the limit on the lifting plate 205d. At this time, under the thrust of the fifth spring 205b, the lifting plate 205d can drive the top rod 205e to move upward, so that the top rod 205e drives the push rod 201b to move upward, so that the rotating clamp 201h has a greater clamping force, so that the two friction plates 201i are brought closer to the middle, thereby clamping and fixing the transmission line, so that the broken transmission line will not fall off the insulator.

[0066] When the lifting plate 205d drives the top rod 205e to move upward, the monitor 205i can detect the approach of the limit block 205g, thereby sending a signal to the base station, improving the accuracy and efficiency of fault location and providing convenience for subsequent maintenance work.

[0067] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, which should all be included in the scope of the claims of the present invention.
