Description

Technical Field

[0001] The invention relates to the technical field of insulators, and more particularly to a strong and tough column type porcelain insulator for high voltage lines. Background Art

[0002] Strong and tough post porcelain insulators for high voltage lines are specially designed for high voltage transmission lines. They combine high strength and toughness to ensure reliability and durability under high voltage and harsh environments.

[0003] Strong and tough column porcelain insulators for high-voltage lines are generally used in township power lines (commonly known as: telephone poles), line insulators, and can play an important role in overhead transmission lines; slowly developed at one end of the high-type high-voltage wire connection tower, many suspended insulators are hung, it is to increase the creepage distance, usually made of silicone or ceramic, called insulators; insulators play two basic roles in overhead transmission lines, namely supporting the conductors and preventing the current from returning to the ground; because the cable length between insulators is generally long, the cable is extremely easy to swing, especially in strong winds or other bad weather, the cable will swing and exert tension on the insulator, and the interaction between electromagnetics in no wind can also cause the cable to swing, which can easily cause the insulator to be damaged and affect the normal use of the high-voltage power grid.

[0004] In view of the above problems, some solutions are also provided in the prior art. For example, the Chinese utility model patent with announcement number CN218274124U discloses a strong column porcelain insulator for high-voltage lines. By setting a reinforced connection component and a tensile buffer component, when the insulator is pulled by strong wind or external force, the upper connection plate and the lower connection plate can pull the connecting rod to move backward, and squeeze the second spring to perform a certain force unloading, thereby enhancing the use effect of the device; although the prior art can buffer the force unloading to a certain extent to protect the insulator, since insulators are generally used outdoors at high altitudes, the reinforced connection component and the tensile buffer component are exposed to the outside for a long time, resulting in external rainwater and impurities easily adhering to the surface of the reinforced connection component and the tensile buffer component, which can easily cause the reinforced connection component and the tensile buffer component to be corroded and fail, thereby easily affecting the use effect of the insulator.

[0017] Furthermore, the top wall of the mounting plate is an inclined surface.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] (1) In this solution, the buffer spring and the first telescopic tube cooperate with each other. When the cable shakes and pulls the insulator body through the joint, the first spring can buffer the tension on the insulator, thereby extending the service life of the insulator body. The first telescopic tube can isolate the buffer spring from the outside world, thereby effectively preventing dust or rain from the outside from falling on the surface of the buffer spring, causing the buffer spring to rust and corrode and lose its elasticity, and affecting the normal buffering of the tension on the insulator body, thereby extending the service life of the insulator body.

[0020] (2) In this solution, by providing a brush, during the process of the first telescopic tube extending and retracting back and forth, the first telescopic tube drives the annular telescopic tube to extend and retract back and forth through the separation component and the first air pipe, and then drives the slider to slide back and forth along the annular groove during the process of the annular telescopic tube extending and retracting back and forth. During the process of the slider sliding back and forth, the brush is driven by the mounting block, the round rod, and the mounting rod to clean the insulator body, thereby preventing the insulator body from being continuously contaminated and flashing, resulting in a reduction in service life. In addition, during the process of the annular telescopic tube extending and retracting back and forth, the impact force on the insulator body can also be consumed, thereby further improving the service life of the insulator body.

[0021] (3) This solution separates the components. After the insulator body is cleaned, the temperature of the insulator body decreases. At this time, the temperature of the memory alloy wire decreases and shrinks. Then, during the shrinkage of the memory alloy wire, the round rod is moved by the push block and the push rod. During the movement of the round rod, the brush bristles are driven to break contact with the insulator body through the mounting rod, thereby avoiding an increase in the conductive path of the insulator body, making the insulator body easily damaged by electric shock, and further extending the service life of the insulator body.

[0038] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention; it is obvious that the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments, and all other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making creative work are within the scope of protection of the present invention.

[0039] See also Figures 1 to 7 , a strong column type porcelain insulator for high voltage lines, comprising a base 13 and an insulator body 1, wherein a joint 2 is installed on the top wall of the insulator body 1;

[0040] A mounting plate 301 is fixedly mounted on the bottom wall of the insulator body 1, a buffer spring 302 is fixedly mounted between the top wall of the base 13 and the mounting plate 301, a first telescopic tube 303 is fixedly mounted between the base 13 and the mounting plate 301, and the buffer spring 302 is located in the first telescopic tube 303, limiting holes are evenly arranged on the mounting plate 301, a limiting rod 304 that slidably cooperates with the limiting holes is fixedly mounted on the base 13, and a cleaning component 4 that cooperates with the insulator body 1 is provided on the base 13.

[0041] The cleaning component 4 includes an annular groove 401 provided on the top wall of the base 13, a slider 402 is slidably installed in the annular groove 401, a mounting block 403 is provided on the top wall of the slider 402, a round rod 404 is provided on the mounting block 403, a mounting rod 405 is fixedly installed on the top wall of the round rod 404, bristles 406 for cleaning the insulator body 1 are evenly fixedly installed on the mounting rod 405, and a driving component 5 cooperating with the slide groove is provided in the annular groove 401.

[0042] The driving assembly 5 includes an annular spring 501 fixedly installed between the slider 402 and the annular groove 401, and an annular telescopic tube 502 is fixedly installed between the slider 402 and the annular groove 401. A first air pipe 503 connected to the annular telescopic tube 502 is inserted into the annular groove 401. A separation assembly 6 for separating the cleaning assembly 4 from the insulator body 1 is provided on the base 13, and the first air pipe 503 is connected to the first telescopic tube 303 through the separation assembly 6.

[0043] When the cable shakes, the cable will apply tension to the insulator body 1 through the joint 2, and then under the action of the tension, the insulator body 1 drives the mounting plate 301 to reciprocate up and down along the limit rod 304. During the reciprocating up and down movement of the mounting plate 301, the buffer spring 302 is stretched back and forth, and the buffer spring 302 is deformed. Then the deformed buffer spring 302 can buffer the tension exerted on the insulator body 1, thereby delaying the service life of the insulator body 1, and when the cable stops exerting tension on the insulator body 1, the buffer spring 302 contracts and drives the insulator body 1 to reset. Since the insulator body 1 is generally outdoors at high altitude, the buffer spring 302 can be isolated from the outside world by providing the first telescopic tube 303, thereby effectively preventing external dust or rain from falling on the surface of the buffer spring 302, causing the buffer spring 302 to rust and corrode and lose its elasticity, and affecting the normal buffering of the tension exerted on the insulator body 1. In addition, the buffer spring 302 is generally not easy to replace since it is at high altitude, thereby extending the service life of the insulator body 1.

[0044] When stains and dust accumulate on the surface of the insulator body 1, local discharge will be formed inside the insulator body 1, that is, dirty flashover will occur, which will cause energy accumulation and release, thereby causing the temperature of the insulator body 1 to rise, and the service life of the insulator body 1 will be reduced; in the process of the mounting plate 301 stretching the buffer spring 302 back and forth, the first telescopic tube 303 stretches back and forth, and then in the process of the first telescopic tube 303 being compressed, the airflow in the first telescopic tube 303 flows into the annular telescopic tube 502 through the separation component 6 and the first air pipe 503, and the gas pressure in the first telescopic tube 303 is increased, and then under the action of pressure, the first telescopic tube 303 stretches and drives the slider 402 to slide along the annular groove 401, and in the process of the slider 402 sliding, the annular spring 501 is stretched and has a tendency to recover, and then in the process of the slider 402 moving During the process, the round rod 404 is driven to move by the mounting block 403, and then the bristles 406 are driven to move by the mounting rod 405 during the movement of the round rod 404. When the buffer spring 302 drives the first telescopic tube 303 to extend, the first telescopic tube 303 inhales air from the annular telescopic tube 502 through the classification component and the first air pipe 503. At this time, the annular spring 501 contracts and drives the slider 402 to reset. During the resetting of the slider 402, the bristles 406 are driven to reset by the mounting block 403, the round rod 404 and the mounting rod 405. That is, during the process of the buffer spring 302 buffering the insulator body 1, the bristles 406 are driven to rotate by the first telescopic tube 303, and the stains on the outside of the insulator body 1 are cleaned, thereby preventing the insulator body 1 from being continuously polluted and flashing, resulting in a reduction in service life, and further improving the service life of the insulator body 1.

[0045] like Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown, the separation component 6 includes a mounting groove provided on the base 13, a push block 601 is slidably installed in the mounting groove, a first spring 606 is fixedly installed between the push block 601 and the mounting groove, a second air pipe 602 connected to the first telescopic tube 303 is provided on the push block 601, and the second air pipe 602 is connected to the annular telescopic tube 502 through the first air pipe 503, a memory alloy wire 603 is fixedly installed between the push block 601 and the mounting groove, a heat conducting rod 604 fitted with the insulator body 1 is fixedly installed on the memory alloy wire 603, a linkage groove is provided on the base 13, a push rod 607 fixedly connected to the push block 601 is slidably installed in the linkage groove, and an inclined groove 608 is provided on the side of the push rod 607 close to the round rod 404, and a linkage component 9 matching the round rod 404 is provided on the mounting block 403.

[0046] The linkage assembly 9 includes a horizontal groove 901 provided on the mounting block 403, a linkage block 905 slidably installed in the horizontal groove 901 and rotatably cooperated with the round rod 404, a return spring 902 is provided between the round rod 404 and the horizontal groove 901, a limiting groove 903 connected to the horizontal groove 901 is provided on the top wall of the base 13, and a connecting pipe 904 connected to the outside is inserted on the bottom wall of the mounting groove.

[0047] By adopting the above technical solution, in the initial state, the memory metal wire is in a contracted state, at which time the first spring 606 and the reset spring 902 are both in a stretched state. When stains are attached to the surface of the insulator body 1, the temperature of the insulator body 1 will gradually increase. At this time, the heat conducting rod 604 transfers the temperature to the memory alloy wire 603, and then the memory alloy wire 603 is stretched by heat. At this time, the first spring 606 contracts and drives the push block 601 to move. During the movement of the push block 601, the push rod 607 is driven to break contact with the round rod 404. At this time, the reset spring 902 contracts and drives the round rod 404 to reset through the linkage block 905. During the reset of the round rod 404, the brush is driven by the mounting rod 405. The bristles 406 gradually come into contact with the insulator body 1, and after the bristles 406 are in contact with the surface of the insulator body 1, the moving push block 601 drives the second air pipe 602 to communicate with the first air pipe 503. At this time, the airflow in the first telescopic tube 303 can flow into the annular telescopic tube 502 through the second air pipe 602 and the first air pipe 503. As the stains on the surface of the insulator body 1 are cleaned, the flashover of the insulator body 1 is weakened, and then the temperature of the insulator body 1 gradually decreases. At this time, the memory alloy wire 603 gradually returns to normal temperature, and then the memory alloy wire 603 gradually contracts. In the process of contraction of the memory alloy wire 603, the push block 601 is driven to move and stretch the first spring 606. During the movement of the block 601, the push rod 607 is driven to move, and then during the movement of the push block 601, the second air pipe 602 is driven to break contact with the first air pipe 503, and at this time, the first air pipe 503 is connected to the outside through the installation groove and the connecting pipe 904, and then the annular spring 501 contracts and drives the annular telescopic tube 502 to reset. During the reset of the annular telescopic tube 502, the air flow in the annular telescopic tube 502 flows to the outside through the first air pipe 503, the installation groove, and the connecting pipe 904. During the contraction of the reset spring 902, the slider 402 is reset through the linkage block 905, and then during the reset of the slider 402, the round rod 404 is reset through the installation block 403. During the resetting process of the round rod 404, it gradually contacts with the inclined groove 608 of the push rod 607, and then the inclined groove 608 of the push rod 607 drives the round rod 404 to move along the horizontal groove 901 toward the limiting groove. During the movement of the round rod 404, the bristles 406 gradually disengage from the insulator body 1, and then after the insulator body 1 is cleaned, the bristles 406 can be disengaged from the insulator body 1, thereby avoiding the bristles 406 and the insulator body 1 from fitting when the surface of the insulator body 1 does not need to be cleaned, resulting in the insulation effect of the insulator body 1 being weakened and the conductive path being increased, making the insulator body 1 easy to be damaged by electric shock, thereby further extending the service life of the insulator body 1.

[0048] like Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7As shown, a cleaning cavity 101 is provided on the mounting rod 405, cleaning holes 102 cooperating with the bristles 406 are evenly provided on the cleaning cavity 101, a third air pipe 103 is inserted on the cleaning cavity 101, an air groove 104 is provided on the base 13, an exhaust valve 105 is inserted on the air groove 104, and the output end of the exhaust valve 105 is connected to the third air pipe 103, and an air intake valve 106 connected to the outside is inserted on the air groove 104.

[0049] A cleaning rod 107 is rotatably mounted on the top wall of the base 13, a combing rod 108 cooperating with the bristles 406 is evenly and fixedly mounted on the cleaning rod 107, a wind cup 109 is fixedly mounted on the top wall of the cleaning rod 107, a groove connected to the horizontal groove 901 is formed on the slider 402, a tooth groove 1010 is formed on the side wall of the groove, and a gear 1011 meshing with the tooth groove 1010 is fixedly mounted on the bottom end of the round rod 404.

[0050] By adopting the above technical solution, in the process that the memory alloy wire 603 contracts and drives the push block 601 to move, the push block 601 drives the second air pipe 602 to contact with the air groove 104, and then in the process that the first telescopic tube 303 extends, the first telescopic tube 303 inhales air from the outside through the second air pipe 602, the air groove 104, and the air inlet valve 106, and then in the process that the first telescopic tube 303 is compressed, the gas in the first telescopic tube 303 flows to the cleaning chamber 101 through the second air pipe 602, the air groove 104, and the exhaust valve 105, and is blown to the bristles 406 through the cleaning hole 102 on the cleaning chamber 101, so that the bristles 406 can be cleaned, so that the stains on the bristles 406 gradually break away from the contact with the bristles 406, thereby improving the cleaning effect of the insulator body 1.

[0051] In the process of the inclined surface of the push rod 607 driving the round rod 404 to move, the round rod 404 drives the gear 1011 to move along the groove, and then the gear 1011 rotates under the action of the tooth groove 1010, and in the process of the rotation of the gear 1011, the mounting rod 405 is driven to rotate through the round rod 404, and the bristles 406 are driven to rotate during the rotation of the mounting rod 405. When the round rod 404 reaches the maximum displacement, the bristles 406 contact the combing rod 108. At the same time, the wind cup 109 is driven to rotate in the process of wind blowing through the wind cup 109, and then the combing rod 108 is driven to rotate through the cleaning rod 107 during the rotation of the wind cup 109. In the process of the rotation of the combing rod 108, the bristles 406 can be hit and the bristles 406 can also be combed, so that the bristles 406 can be hit and combed while blowing air on the bristles 406, which further improves the cleaning effect of the bristles 406.

[0052] like Figure 1As shown, an annular plate 11 for sealing the annular groove 401 is fixedly mounted on the mounting block 403 .

[0053] By adopting the above technical solution, when the slider 402 drives the mounting block 403 to rotate along the annular groove 401, the mounting block 403 drives the annular plate 11 to rotate, and then the rotating annular plate 11 can always block the annular groove 401, thereby preventing external dust from entering the annular groove 401 and affecting the normal sliding of the slider 402.

[0054] like Figure 1 As shown, the top wall of the limiting rod 304 is fixedly mounted with the limiting plate 12 .

[0055] By adopting the above technical solution, when the mounting plate 301 slides along the limiting rod 304, the limiting plate 12 can be provided to limit the reciprocating mounting plate 301, thereby preventing the mounting plate 301 from detaching from the limiting rod 304 and affecting the normal operation of the mounting plate 301.

[0056] like Figure 1 As shown, the top wall of the mounting plate 301 is an inclined surface.

[0057] By adopting the above technical solution, during the process of cleaning the insulator body 1 with the brush plate, some stains on the surface of the insulator body 1 will fall onto the top wall of the mounting plate 301. By making the top wall of the mounting plate 301 an inclined surface, the stains on the top wall of the mounting plate 301 can be easily dropped downward along the inclined surface, thereby further improving the cleaning effect.

[0058] Instructions for use: When the cable vibrates, the cable applies a pulling force to the insulator body 1 through the connector 2. Then, under the action of the pulling force, the insulator body 1 drives the mounting plate 301 to reciprocate up and down along the limit rod 304. During the reciprocating up and down movement of the mounting plate 301, the buffer spring 302 is stretched back and forth, causing the buffer spring 302 to deform. Then, the deformed buffer spring 302 can buffer the pulling force on the insulator body 1, thereby delaying the service life of the insulator body 1. When the cable stops applying a pulling force to the insulator body 1, the buffer spring 302 contracts and drives the insulator body 1 to reset. Since the insulator body 1 is generally outdoors at high altitude, the buffer spring 302 can be retracted by setting the first telescopic tube 303. The spring 302 is isolated from the outside world; during the process of the first telescopic tube 303 extending and retracting back and forth, the first telescopic tube 303 drives the annular telescopic tube 502 to extend and retract through the separation component 6 and the first air pipe 503, and then drives the slider 402 to slide back and forth along the annular groove 401 during the process of the annular telescopic tube 502 extending and retracting, and drives the brush 406 to clean the insulator body 1 through the installation block 403, the round rod 404, and the installation rod 405 during the process of the slider 402 sliding back and forth; after the temperature of the insulator body 1 decreases, the temperature of the memory alloy wire 603 decreases and shrinks, and then during the process of the memory alloy wire 603 shrinking, the round rod 404 is moved by the push block 601 and the push rod 607, and during the movement of the round rod 404, the brush 406 is driven by the installation block 403, the round rod 404, and the installation rod 405. The brush bristles 406 are driven to be out of contact with the insulator body 1 through the mounting rod 405, thereby avoiding an increase in the conductive path of the insulator body 1; in the process of the memory alloy wire 603 contracting and driving the push block 601 to move, the push block 601 drives the second air pipe 602 to contact the air groove 104, and then in the process of the first telescopic tube 303 extending, the first telescopic tube 303 inhales air from the outside through the second air pipe 602, the air groove 104, and the air inlet valve 106, and then in the process of the first telescopic tube 303 being compressed, the gas in the first telescopic tube 303 flows to the cleaning chamber 101 through the second air pipe 602, the air groove 104, and the exhaust valve 105, and is blown to the brush bristles 406 through the cleaning hole 102 on the cleaning chamber 101; During the movement of the movable round rod 404, the round rod 404 drives the gear 1011 to move along the groove, and then the gear 1011 rotates under the action of the tooth groove 1010, and during the rotation of the gear 1011, the mounting rod 405 is driven to rotate through the round rod 404, and during the rotation of the mounting rod 405, the bristles 406 are driven to rotate. When the round rod 404 reaches the maximum displacement, the bristles 406 contact the combing rod 108. At the same time, the wind cup 109 is driven to rotate in the process of wind blowing through the wind cup 109, and then the combing rod 108 is driven to rotate through the cleaning rod 107 in the process of the wind cup 109 rotating. During the rotation of the combing rod 108, the bristles 406 can be hit, and the bristles 406 can also be combed.

[0059] The above is only a preferred specific implementation of the present invention; however, the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solution and its improved conception within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
