[0002] Insulators are important components in high-voltage transmission lines, and their performance directly affects the stable operation of the power system. If the insulators fail, it may lead to a short circuit in the line, and in severe cases, even cause a large-scale power outage accident. By regularly detecting the resistance value of the insulators, potential problems can be discovered in time to prevent accidents, thus ensuring the safety and reliability of the intelligent power distribution system.

[0003] The insulation push-pull disc device for detecting the resistance of high-voltage overhead line insulators with the publication number of CN200976027Y slides between the double-insulator strings through a boat-shaped support structure, and adjusts the rotation of the detection probe through a transmission structure to detect the resistance of the double-insulator strings.

[0040] Compared with the prior art, the following beneficial effects are achieved:

[0041] 1. The present invention restricts the detachment of the frame body from the insulator through the support mechanism and facilitates the sliding of the frame body between the double-circuit insulator strings.

[0042] 2. The present invention makes the bottom length of the frame body less than the distance between the two cables and the top length of the frame body greater than the distance between the two cables, so as to facilitate placing the frame body between the two cables of the double-circuit insulator string, and makes the insulators arranged side by side in the double-circuit insulator string located in the sliding grooves on both sides of the frame body respectively, restricting the detachment of the frame body from the insulator and facilitating the sliding of the frame body between the double-circuit insulator strings.

[0043] 3. The present invention enables the two moving plates to move along the Y-axis direction and the direction opposite to the Y-axis while the moving plate moves along the X-axis, which can synchronously drive the two moving frames to move along the Y-axis direction and the direction opposite to the Y-axis, facilitating the movement of the frame body and facilitating the resetting of the moving plate and the moving frame after the movement is completed. By repeating this process, it is convenient to detect multiple insulators on the double-circuit insulator string.

[0044] 4. The present invention limits the position through the moving frame while the moving plate is pushing backward, so as to prevent the frame body and the like from continuing to slide a certain distance under the action of inertia and the like after the first electric push rod pushes the moving plate to a specified length, so that the detection mechanism can accurately contact the steel cap, facilitating the detection of the resistance of the insulator.

[0045] 5.

[0078] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0079] Embodiment 1: Please refer to Figure 1 、 Figure 2 、 Figure 3 and Figure 4 , a push-pull disc device for detecting the resistance of overhead line insulators based on an intelligent power distribution system, including a double insulator string. The double insulator string includes a cable 3, insulators 1 spaced on the surface of the cable 3, and steel caps 2 provided on both sides of the insulators 1. It further includes a support mechanism 4, and the support mechanism 4 includes:

[0080] A frame body 41. Sliding grooves 42 for sleeving on the surface of the insulator 1 are opened on both sides of the frame body 41, so that the frame body 41 is located between the double insulator strings. The bottom length 43 of the frame body 41 is less than the distance between the two cables 3, and the top length 44 of the frame body 41 is greater than the distance between the two cables 3 to prevent the frame body 41 from detaching from the double insulator string. An installation through groove 45 is opened on one side of the frame body 41 along the length direction of the cable 3. A moving mechanism 5 for driving the frame body 41 to move at equal intervals is arranged inside the installation through groove 45. A detection mechanism 7 for detecting the resistance of the insulator 1 is arranged on the top of the frame body 41.

[0081] In specific implementation, by making the bottom length 43 of the frame body 41 less than the distance between the two cables 3 and the top length 44 of the frame body 41 greater than the distance between the two cables 3, it is convenient to place the frame body 41 between the two cables 3 of the double insulator string. And through the sliding grooves 42, the insulators 1 arranged side by side in the double insulator string are respectively located in the sliding grooves 42 on both sides of the frame body 41. At this time, the frame body 41 is prevented from detaching from the insulator 1 by the top length 44 and the bottom length 43 of the frame body 41, and it is convenient for the frame body 41 to slide between the double insulator strings. Thus, under the action of the moving mechanism 5 and through the reaction force, the frame body 41 and the detection mechanism 7 are driven to move at equal intervals according to the spacing between the insulators 1, so that the detection mechanism 7 is accurately and stably located on the top of the steel cap 2, thereby facilitating the detection of the resistance of the insulator 1.

[0082] By providing the installation through groove 45, it is convenient for the moving mechanism 5 to drive the frame body 41 and the detection mechanism 7 to move between the double insulator strings, so as to drive the frame body 41 and the detection mechanism 7 to move at equal intervals according to the spacing between the insulators 1 through the reaction force, thereby facilitating the detection of the resistance of the insulator 1;

[0083] The length of the frame body 41 along the X-axis is such that during the movement of the frame body 41, the inner wall of the sliding groove 42 can always contact two adjacent insulators 1, thereby ensuring the stability of the frame body 41.

[0084] Embodiment 2: Please refer to Figure 5 、 Figure 6 、 Figure 10 、 Figure 11 、 Figure 12 、 Figure 13 、 Figure 14 、 Figure 15 and Figure 17 , the different technical solution of this embodiment compared with Embodiment 1 is that the moving mechanism 5 includes:

[0085] A moving component 51, symmetrically arranged in the installation through groove 45 with respect to the center point of the installation through groove 45. The moving component 51 includes:

[0086] A moving plate 511, sleeved in the installation through groove 45, and the end extends outside the installation through groove 45. One end of the moving plate 511 outside the installation through groove 45 is bent outward to form a first bending structure 516.

[0087] The moving mechanism 5 further includes:

[0088] An abutting plate 52, fixedly arranged on the bottom inner wall of the installation through groove 45 and located between two moving components 51. First inclined surfaces 53 are provided on both sides of the abutting plate 52. Guide rods 54 are fixedly arranged on both sides of the abutting plate 52, and both ends of the guide rods 54 are fixedly connected to the inner walls on both sides of the installation through groove 45. A guide groove 5193 for sleeving the guide rods 54 is provided on the side wall of the moving plate 511;

[0089] A first electric push rod 56, fixedly arranged on the bottom inner wall of the installation through groove 45. The end of the telescopic shaft of the first electric push rod 56 is fixedly provided with a connecting piece 55 to connect the moving plates 511 of two moving components 51 through the free ends 57 on both sides of the connecting piece 55. An inclined groove 58 for limiting the free ends 57 of the connecting piece 55 is provided on the bottom inner wall of the installation through groove 45;

[0090] The moving component 51 further includes:

[0091] A second inclined surface 5192, provided on the side of the moving plate 511 close to the abutting plate 52. The second inclined surface 5192 cooperates with the first inclined surface 53 so that when the moving plate 511 moves along the X-axis direction, it can move along the Y-axis direction and the direction opposite to the Y-axis.

[0092] The moving component 51 further includes:

[0093] The moving frame 512 is sleeved in the installation through groove 45. A limiting component 515 is arranged on the side wall of the moving frame 512 to limit the moving frame 512 and the moving plate 511 through the limiting component 515, and enable the moving frame 512 and the moving plate 511 to move relatively. The inner side of the moving frame 512 is sleeved on the side wall of the moving plate 511. First tooth grooves 5195 are formed in both the top inner wall and the bottom inner wall of the moving frame 512, and second tooth grooves 5194 are formed in both the top and the bottom of the moving plate 511;

[0094] The adjusting plate 514 is embedded in both inner side walls of the installation through groove 45. Disassembly and assembly components 517 are arranged on both the top and the bottom of the adjusting plate 514 to disassemble and assemble rotatable first gears 518 on the top and the bottom of the adjusting plate 514 through the disassembly and assembly components 517. First through grooves 5196 communicating with the first tooth grooves 5195 are formed in both the upper end and the lower end of the side wall of the moving frame 512. The first gears 518 are respectively engaged with the first tooth grooves 5195 and the second tooth grooves 5194 along the first through grooves 5196 to drive and connect the moving plate 511 and the moving frame 512.

[0095] One side of the moving frame 512 far away from the first bending structure 516 bends outward to form a second bending structure 5191, and an inner groove 519 is arranged on the concave surface of the second bending structure 5191. Buffer components 513 are arranged at intervals on the inner wall of the inner groove 519 to limit the bending degree of the second bending structure 5191.

[0096] In specific implementation, when the moving plate 511 moves to a position with a support point, that is, when it can abut against the surface of the insulator 1, the first electric push rod 56 is started. The telescopic shaft of the first electric push rod 56 drives the connecting member 55 to move, thereby driving the moving plates 511 of the two moving assemblies 51 to move synchronously. During the movement of the moving plate 511, through the cooperation of the first inclined surface 53 and the second inclined surface 5192, and through the cooperation of the free end 57 of the connecting member 55 and the inclined groove 58, while the moving plate 511 moves along the X-axis, the two moving plates 511 can move along the Y-axis and the direction opposite to the Y-axis, so as to abut against the surface of the insulator 1 through the first bending structure 516. As the moving plate 511 continues to move, the frame 41 slides along between the double-circuit insulators 1 through the reaction force. At the same time, during the movement of the moving plate 511, the moving frame 512 is driven to move in the reverse direction through the transmission of the first gear 518, the first tooth groove 5195 and the second tooth groove 5194. And under the action of the limiting component 515, the two moving plates 511 synchronously drive the two moving frames 512 to move along the Y-axis and the direction opposite to the Y-axis, so as to abut against the rear insulator 1 through the second bending mechanism. Thus, while the frame 41 and the detection mechanism 7 are driven to move by the reaction force of the moving plate 511, the moving frame 512 is used for limiting, so as to prevent the frame 41 etc. from continuing to slide for a certain distance under the action of inertia etc. after the first electric push rod 56 pushes the moving plate 511 to a specified length, so that the detection mechanism 7 can accurately contact the steel cap 2, in order to facilitate the resistance detection of the insulator 1.

[0097] After one detection is completed, the telescopic shaft of the first electric push rod 56 is reset, so that the free end 57 of the connecting member 55 is reset under the limitation of the inclined groove 58, thereby driving the moving frame 512 and the moving plate 511 to reset. At this time, the moving plate 511 and the moving frame 512 are located between the double-circuit insulators 1, and at this time the frame 41 has completed a certain distance of displacement. As the telescopic shaft of the first electric push rod 56 extends again, the frame 41 and the detection mechanism 7 etc. move according to the distance between the insulators 1. And the distance between the insulators 1 in the double-circuit insulator string 1 is usually the same, so that the frame 41 and the detection mechanism 7 move at equal distances, in order to facilitate the accurate detection of the insulator 1 by the detection mechanism 7. By circulating in this way, it is convenient to detect multiple insulators 1 on the double-circuit insulator string 1.

[0098] During the reset process of the moving plate 511 and the moving frame 512, the probe 71 and the sleeve rod 791 of the detection mechanism 7 are located between adjacent insulators 1, so as to limit the frame 41 etc., in order to facilitate the next movement of the moving mechanism 5.

[0099] By providing the first inclined surface 53 and the second inclined surface 5192, when the moving plate 511 moves along the X-axis direction, the second inclined surface 5192 and the first inclined surface 53 gradually come into contact and press against each other, so that the moving plate 511 can move along the Y-axis direction and the direction opposite to the Y-axis during the movement along the X-axis direction;

[0100] Through the cooperation of the inclined groove 58, the connecting member 55, the guide rod 54 and the guide groove 5193, the stability of the movement of the moving plate 511 is ensured, and in cooperation with the limiting component 515, the stability of the movement of the moving plate 511 and the moving frame 512 is further ensured. In the specific design, the top and bottom outer walls of the moving frame 512 are fitted with the top and bottom inner walls of the installation through groove 45, further improving the stability of the movement of the moving frame 512;

[0101] By providing the first bending structure 516 and the second bending structure 5191, it is convenient for the moving plate 511 to be located between the side-by-side insulators 1 when it is reset. During the movement of the moving plate 511, the insulators 1 are resisted. The parts of the first bending structure 516 and the second bending structure 5191 in contact with the insulators 1 can be embedded with soft materials such as rubber to avoid damaging the insulators 1.

[0102] The length of the first gear 518 along the Y-axis direction is greater than the distance that the moving plate 511 and the moving frame 512 move along the Y-axis direction and the direction opposite to the Y-axis, so as to ensure that the first gear 518 can drive the moving frame 512 and the moving plate 511 during the movement along the Y-axis direction and the direction opposite to the Y-axis. During the driving process, the moving plate 511 moves slowly, so as to ensure the stability of the driving of the first gear 518. By providing the first through groove 5196, it is ensured that the moving frame 512 has enough moving space when moving in the direction opposite to the X-axis and does not affect the meshing with the first tooth groove 5195 and the second tooth groove 5194.

[0103] The connecting member 55 is set as a telescopic structure, so that after the two free ends 57 on both sides of the connecting member 55 are connected to the side of the moving plate 511 close to each other, when the moving plate 511 moves along the Y-axis direction and the direction opposite to the Y-axis, the connecting member 55 can correspondingly expand and contract, thus avoiding movement obstacles.

[0104] Please refer to Figure 15 and Figure 16 , the buffer assembly 513 includes:

[0105] Arc spring pieces 5132, fixedly arranged on the inner wall of the inner groove 519. Buffer blocks 5133 are fixedly arranged at both ends of the concave surface of the arc spring pieces 5132. Rubber sleeves 5131 are fixedly sleeved on the sides of the buffer blocks 5133 close to each other.

[0106] In specific implementation, during the process that the moving frame 512 abuts against the rear insulator 1 through the second bending structure 5191, the inner groove 519 enables the second bending structure 5191 to have a space for inward bending after abutting against the rear insulator 1, thereby avoiding rigid contact between the moving frame 512 and the insulator 1, and enabling the buffer block 5133 and the rubber sleeve 5131 to limit the bending degree of the second bending structure 5191, having a buffering effect and at the same time having an effect of stably supporting the insulator 1.

[0107] Please refer to Figure 18 , the limiting component 515 includes:

[0108] Limiting through grooves 5152 are opened on the side walls of the moving plate 511 and the moving frame 512. The inner walls of the limiting through grooves 5152 are sleeved with limiting rods 5153 arranged at intervals, and both ends of the limiting rods 5153 extend outside the limiting through grooves 5152. Both ends of the limiting rods 5153 are designed to protrude outward, so that the sides of the moving frame 512 and the moving plate 511 that are close to each other are in contact, and the separation of the moving plate 511 and the moving frame 512 is restricted. Limiting grooves 5151 are opened on the inner walls of the limiting through grooves 5152 on the side wall of the moving plate 511. The inner walls of the limiting grooves 5151 are sleeved with limiting plates arranged at intervals and in contact with them, and the limiting plates are all located between the limiting rods 5153. A first spring is fixedly arranged on the side of the limiting plates that are close to each other.

[0109] In specific implementation, by moving the limiting rods 5153 in the limiting through grooves 5152 and designing both ends of the limiting rods 5153 to protrude outward, when the moving plate 511 and the moving frame 512 move along the X-axis direction and the direction opposite to the X-axis, the limiting plates and the limiting frame are always in contact, so that when the moving plate 511 moves along the Y-axis, it can drive the moving frame 512 to move along the Y-axis;

[0110] The spaced-apart limiting rods 5153 are elastically supported by the first spring and the limiting plates, so that the two limiting rods 5153 are as far as possible on both sides of the moving plate 511, thereby improving the stability of limiting the moving plate 511 and the moving frame 512, and by moving the limiting plates in the limiting grooves 5151, the first spring is prevented from detaching.

[0111] Please refer to Figure 19 , Figure 20 , Figure 21 and Figure 22 , the disassembly and assembly component 517 includes:

[0112] A disassembly and assembly plate 5171 is rotatably arranged at the central axis of the first gear 518. A first clamping plate 5172 is fixedly arranged at the bottom of the disassembly and assembly plate 5171. First clamping grooves 5173 are opened on both sides of the first clamping plate 5172:

[0113] The second slot 5174 is provided at the top of the adjustment plate 514. The inner walls of both sides of the second slot 5174 are provided with third slots 5175. The inner walls of the third slot 5175 are provided with disassembly grooves 5176. The inner walls of the disassembly grooves 5176 are fixed with abutment rods 5178. The side walls of the abutment rods 5178 are sleeved with abutment members 5177. The outer wall of the abutment member 5177 fits with the inner wall of the disassembly groove 5176. The end of the abutment member 5177 close to the second slot 5174 extends into the third slot 5175. The end of the abutment member 5177 located in the third slot 5175 is fixed with a second clamping plate 5170 adapted to the third slot 5175. The side wall of the abutment rod 5178 and the side of the abutment member 5177 away from the second clamping plate 5170 are sleeved with a second spring. One side of the second clamping plate 5170 is designed in an arc shape:

[0114] The shift plate 5179 is fixed on the outer wall of the abutment member 5177 and extends into the frame body 41. The side wall of the adjustment plate 514 is provided with a shift groove connected to the disassembly groove 5176. Both sides of the frame body 41 are provided with operating grooves 5197 for disassembling and assembling the first gear 518.

[0115] In a specific implementation, in the intelligent power distribution system, due to the different voltages transmitted, the spacings of the insulators 1 on different strings of double insulators 1 are different. In order to increase the applicability, the distances of the moving frame 512 driven by the transmission during the movement of the moving plate 511 are different, so as to facilitate adjustment according to the actual detection situation. Therefore, the first gear 518 can be separated from the meshing of the first tooth groove 5195 and the second tooth groove 5194 by the disassembly assembly 517, so as to facilitate the adjustment of the relative distance between the moving plate 511 and the moving frame 512, so as to facilitate the actual detection use.

[0116] When operating the disassembly and assembly component 517, the first clamping plate 5172 is inserted into the second clamping slot 5174. During this process, the second clamping plate 5170 drives the abutment member 5177 to squeeze the second spring along the side wall of the abutment rod 5178 to move. When the second clamping plate 5170 is embedded in the first clamping slot 5173, the disassembly and assembly plate 5171 is installed on the top and bottom of the adjustment plate 514. When disassembling, the dial plate 5179 is pushed to make the dial plate 5179 drive the second clamping plate 5170 to separate from the first clamping slot 5173, thereby facilitating the removal of the first gear 518.

[0117] Example 3: Please refer to Figure 1 , Figure 7 , Figure 8 and Figure 9 The difference between this embodiment and the second embodiment is that the detection mechanism 7 includes:

[0118] The base 74 is movably arranged on the top of the frame body 41. An extension plate 73 is arranged on the top of the base 74 in a lifting manner. Probes 71 are arranged at the bottoms of both sides of the extension plate 73 to be lapped with the steel cap 2 through the probes 71, so as to detect the resistance of the insulator 1. A resistance detector 8 is fixedly arranged on the side wall of the base 74, and the probes 71 are connected to the detection ends of the resistance detector 8.

[0119] The detection mechanism 7 further includes:

[0120] A second electric push rod 78 is fixedly arranged inside the base 74. The telescopic shaft of the second electric push rod 78 is fixedly connected to the bottom of the extension plate 73 to drive the extension plate 73 to lift and lower;

[0121] A telescopic rod 77 is arranged inside the base 74 and is located on both sides of the second electric push rod 78. The telescopic rod 77 is a multi-stage telescopic rod 77. One end of the telescopic rod 77 is fixedly connected to the base 74, and the other end of the telescopic rod 77 is fixedly connected to the bottom of the extension plate 73;

[0122] A sleeve 72 is fixedly sleeved on both sides of the top of the extension plate 73. The middle end of the inner side wall of the sleeve 72 is designed to be concave. A sleeve rod 791 and a sleeve ring 79 are respectively sleeved on the inner wall of the sleeve 72 and the inner wall of the concave part of the sleeve 72. The inner wall of the sleeve ring 79 is fixedly connected to the side wall of the sleeve rod 791. The bottom of the sleeve rod 791 is fixedly connected to the top of the probe 71. A third spring is sleeved on the side wall of one end of the sleeve rod 791 located on the inner wall of the sleeve 72 and on the top of the sleeve ring 79.

[0123] The detection mechanism 7 further includes:

[0124] A threaded rod 76 is rotatably arranged on the side wall of the frame body 41. Sliding grooves symmetrically arranged with the center point of the base 74 are formed at the top of the frame body 41. Sliders are placed inside the sliding grooves, and the tops of the sliders are fixedly connected to the bottom of the base 74. The end of the threaded rod 76 extends into the sliding groove and is in threaded connection with the slider. The two threaded rods 76 are in transmission connection;

[0125] A turntable 75 is rotatably arranged on the side wall of the frame body 41 and is located between the two threaded rods 76. The turntable 75 is in transmission connection with the threaded rods 76.

[0126] During specific implementation, when the frame body 41 and the detection mechanism 7 are moved through the moving mechanism 5, at this time, the probe 71 is located on the top of the steel cap 2. Immediately afterwards, the second electric push rod 78 is started. The telescopic shaft of the second electric push rod 78 drives the extension plate 73 to move, thereby driving the sleeve rod 791 and the probe 71 to move, so that the probe 71 is lapped with the steel cap 2, and the resistance of the insulator 1 is detected;

[0127] There are two resistance detectors 8, so that when the probes 71 are arranged on both sides of the extension plate 73, it is convenient to synchronously detect the resistance of both of the two insulators 1 arranged side by side in the double-insulator string 1, improving the detection efficiency;

[0128] The sleeve rod 791 and the sleeve ring 79 can move vertically along the inner wall of the sleeve 72 and the inner wall of the concave part of the sleeve 72, and under the action of the third spring, the probe 71 has a buffering space, avoiding damaging the probe 71 when the probe 71 contacts the steel cap 2, thus avoiding affecting the actual detection use;

[0129] By designing the multi-stage telescopic rod 77 to limit the lifting of the extension plate 73, the stability of the lifting is improved;

[0130] By enabling the position of the base 74 on the top of the frame body 41 to be adjustable, it is convenient to select the position of the probe 71 according to the relative moving distance between the moving plate 511 and the moving frame 512, ensuring the accuracy of the lifting of the probe 71, thus facilitating the actual detection use.

[0131] Second through grooves are provided on both sides of the top of the frame body 41 to leave a space for adjusting the probe 71;

[0132] A groove for the second electric push rod 78 to move is provided in the middle of the top of the frame body 41;

[0133] A storage battery 6 for power supply is fixedly provided on the top of the frame body 41 to facilitate the actual power supply use.

[0134] The electronic devices such as the first electric push rod 56 and the second electric push rod 78 in the present invention are all connected to the storage battery 6 and an external controller to facilitate the actual control and use. This is the prior art and will not be elaborated here.

[0135] When the present invention is implemented, first place the frame body 41 between the two cables 3 of the double-insulator string 1. Immediately afterwards, slide the frame body 41 to between the double-insulator string 1 through the sliding groove 42. Through the design of the sliding groove 42 and the frame body 41, it is avoided that the frame body 41 is separated from the double-insulator string 1, and it can slide along between the double-insulator string 1.

[0136] After installing the frame body 41, the resistance of a string of double insulators 1 can be detected. During the detection process, there is no support point for the moving plate 511 of the moving mechanism 5. That is, it is necessary for the staff to manually detect the resistance of the first two insulators 1 of a string of double insulators 1. When subsequent resistance detection is carried out, the moving plate 511 of the moving mechanism 5 can abut against the insulator 1, so that the frame body 41 moves through the reaction thrust. And through the cooperation of the moving plate 511 and the moving frame 512, the frame body 41 can move equidistantly according to the spacing of the string of insulators 1, so that the probe 71 of the detection mechanism 7 is accurately located at the top of the steel cap 2. Then, after one movement is completed, the resistance of the insulator 1 can be detected by the detection mechanism 7. As the frame body 41 continuously moves, when it moves to the position of the last insulator 1 of a string of double insulators 1, since there is no support point for the moving frame 512, at this time, it is necessary for the staff to manually assist in the operation to detect the resistance of the insulators 1 of the entire string of double insulators 1. Through the cooperation of the support mechanism 4, the moving mechanism 5 and the detection mechanism 7, the frame body 41 and the detection mechanism 7 can move a specified length according to the spacing between the insulators 1, so that the detection mechanism 7 is accurately located at the top of the steel cap 2, which is convenient for detecting the resistance of the insulator 1 and is also convenient for synchronously detecting the resistance of the two insulators 1 arranged side by side in a string of double insulators 1, improving the detection efficiency.
