Description

Technical Field

[0001] The present invention relates to the technical field of power distribution tools, and in particular to an automatic energy-charging digital power acquisition interval device. Background Art

[0002] During use, high-voltage transmission lines may experience abnormal movements such as breeze vibration, sub-span oscillation and low-frequency dancing, which will cause the air gap between phases to decrease, and then cause electrical problems such as electromagnetic interference and reduced insulation performance, and even phase-to-phase flashover or short-circuit failures, threatening the safe and stable operation of the transmission lines. To improve this phenomenon, phase-to-phase spacers are installed between adjacent conductors. They use high-strength insulating materials to construct a rigid mechanical connection, which effectively separates the conductors of each phase and forms a mutually restrained motion coupling system.

[0003] At present, phase spacers are usually divided into two types: rigid and damping types. Rigid spacers are mainly used for insulating spacing and supporting the connection of adjacent conductors, and are suitable for low wind speed areas. Damping spacers can not only maintain the spacing between adjacent conductors through mechanical connection, but also use their internal damping structure to consume the vibration energy of the conductor when the conductor moves abnormally, thereby suppressing the abnormal movement of the conductor. However, since the damping coefficient of the existing damping spacers is fixed, and the energy characteristics of the conductor at different vibration frequencies are significantly different, this makes the conductor have a small amplitude but a high frequency in high-frequency vibrations (such as breeze vibrations), and the fixed damping is difficult to quickly respond to high-frequency energy changes, resulting in insufficient energy dissipation. In low-frequency vibrations (such as swinging and dancing), the conductor has a large amplitude but a low frequency, and the damping structure cannot adaptively adjust the energy consumption intensity, causing it to reach saturation too early, ultimately resulting in low suppression effect of the damping spacer on abnormal conductor movement. Summary of the invention

[0004] The invention provides an automatic energy-charging digital power acquisition interval device, so as to overcome the disadvantage that the damping coefficient of the existing damping interval rod is fixed, resulting in low suppression effect on abnormal movement of the conductor.

The shielding ring is provided with a connecting groove. The detection component is arranged on the connecting column and is used for detecting the frequency of movement of the connecting column relative to the damping shell.

[0006] Furthermore, the outer diameter of the blocking ring is larger than the minimum distance between the slow flow hole and the central axis of the sliding ring, and the outer diameter of the blocking ring is smaller than the maximum distance between the slow flow hole and the central axis of the sliding ring.

[0008] Furthermore, a damping medium with a small viscosity-temperature coefficient is stored in the damping cavity.

[0009] Furthermore, the detection component includes: An elastic concave ring is fixedly connected to the connecting column, the elastic concave ring and the connecting column are jointly fixedly connected with a flexible ring sheet, the fixed connection between the flexible ring sheet and the connecting column is located between the elastic concave ring and the mounting column, and the connecting column, the elastic concave ring and the flexible ring sheet together constitute a detection cavity; A friction ring is slidably and rotatably connected in the damping shell, and there is friction between the two. The mounting column and the connecting column are both fixedly connected with a limit ring, and the limit ring is used to limit the moving distance of the friction ring. The side of the friction ring close to the elastic concave ring is fixedly connected with an extrusion frame, and the extrusion frame is used to extrude the elastic concave ring; The transmission assembly is arranged in the installation column and is used to control the flow area of ​​the slow flow hole.

[0010] Furthermore, the transmission assembly comprises: An elastic tube is fixedly connected in the connecting column, and the two together form a temporary storage cavity, and the temporary storage cavity is communicated with the detection cavity; A transfer ring, sealingly and rotatably connected between the mounting column and the connecting column, the transfer ring is provided with a transfer through hole, a connecting flow channel is provided in the mounting column, and the transfer through hole is used to connect the connecting flow channel with the temporary storage chamber; An elastic liquid sac is fixedly connected between the sliding ring and the blocking ring, the elastic liquid sac is communicated with the connecting flow channel, and the detection cavity, the temporary storage cavity, the transfer through hole, the connecting flow channel and the elastic liquid sac are all filled with transmission medium; An elastic rope is fixed between the sliding ring and the shielding ring.

On the contrary, when the wire movement frequency is smaller, the flow area of ​​the slow flow hole is in the end smaller, so that the device can consume the movement energy of the wire throughout the movement of the wire, thereby achieving the purpose of controlling the damping coefficient according to the wire movement frequency.

DETAILED DESCRIPTION

[0018] Other features and advantages of the present invention will be described in the following description, and partly become obvious from the description, or be understood by practicing the present invention. The purpose and other advantages of the present invention can be realized and obtained by the structures pointed out in the description and the drawings.

[0019] An automatic charging type digital power interval device, please refer to Figure 1-Figure 4, including: a spacer bar 1; two damping connection units, respectively arranged at both ends of the spacer bar 1, used to install the spacer bar 1 to the conductor and consume the energy during the abnormal movement of the conductor, the damping connection unit includes: a damping shell 2, fixed to the spacer bar 1, a mounting column 3 is sealed and slidably connected in the damping shell 2, and the two together form a damping chamber 301, a connecting column 4 is fixed to the side of the mounting column 3 away from the spacer bar 1, and the connecting column 4 is fixed to a middle connecting block 5 that is slidably connected to the damping shell 2; an electric claw 6, fixed to the middle connecting block 5, and the electric claw 6 is fixed to the mounting shell 7; a sliding ring 8, fixed to the mounting column 3, and sealed and slidable in the damping chamber 301, a spring is fixed between the sliding ring 8 and the mounting column 3, and the sliding ring 8 is provided with a slow flow hole 8 01, a shielding ring 9 is sealed and rotatably connected inside the sliding ring 8, and the shielding ring 9 is used to shield the slow flow hole 801, and the shielding ring 9 is provided with a connecting groove 901; a detection component is arranged on the connecting column 4, and is used to detect the frequency of movement of the connecting column 4 relative to the damping shell 2; the outer diameter of the shielding ring 9 is larger than the minimum distance between the slow flow hole 801 and the central axis of the sliding ring 8, and the outer diameter of the shielding ring 9 is smaller than the maximum distance between the slow flow hole 801 and the central axis of the sliding ring 8; a solar power generation module 701 and a wind power generation module 702 are installed in the mounting shell 7, a battery and a communication module are installed in the mounting shell 7, and the electric clamp 6 is installed with a stress sensor electrically connected to the battery; a damping medium with a small viscosity-temperature coefficient is stored in the damping chamber 301.

[0020] In the above scheme, it is intended to solve the problem that the damping coefficient of the existing damping spacer bar 1 is fixed, resulting in a low inhibitory effect on abnormal movement of the conductor; this scheme monitors the frequency of the conductor movement to control the flow area of ​​the slow flow hole 801, and then changes the damping coefficient of the damping connection unit, and adapts to different movement frequencies of the conductor. When the conductor vibrates at a high frequency, the damping coefficient of the damping connection unit is small, so that the damping connection unit can quickly respond to high-frequency energy changes and consume the movement energy of the conductor. When the conductor vibrates at a low frequency, the damping coefficient of the damping connection unit is large, so that the damping connection unit can consume the movement energy of the conductor throughout the entire process of the conductor movement, thereby enhancing the inhibitory effect on abnormal movement of the conductor.

[0021] The electric clamping claw 6 is composed of a hook block, a screw, a sliding block and a motor. When the hook block of the electric clamping claw 6 is mounted on the wire, the battery in the mounting shell 7 provides power to the motor, so that the motor drives the screw to rotate, and the screw drives the sliding block to move, and clamps the wire together with the hook block. This is an existing device and will not be described in detail in this article; the spring of the sliding ring 8 is initially in a stress-free state; the number of slow flow holes 801 and connecting grooves 901 can be adjusted according to actual conditions. In this article, there are two slow flow holes 801 and connecting grooves 901, and initially the slow flow holes 801 correspond to the adjacent connecting grooves 901, that is, initially the flow area of ​​the slow flow holes 801 is the largest; the outer diameter of the shielding ring 9 is larger than the minimum distance between the slow flow hole 801 and the central axis of the sliding ring 8 and smaller than the distance between the slow flow hole 801 and the sliding groove The maximum distance between the central axes of the shift ring 8 makes it impossible for the shielding ring 9 to completely block the slow flow hole 801; the solar power generation module 701 and the wind power generation module 702 are used to store electricity in the battery in the installation shell 7 through solar energy and wind power, and maintain the signal connection between the communication module and the remote data center; the stress sensor can be a strain gauge, which is used to monitor the stress of the adjacent wires of the electric clamp 6 in real time, and transmit the monitoring data to the communication module in real time, and the communication module transmits the data to the remote data center through the Internet of Things; the damping medium in the damping cavity 301 can be adjusted according to the temperature change range of the use environment of the device, so that the viscosity of the damping medium tends to be consistent at different temperatures, reducing the influence of temperature changes on the damping coefficient. The damping medium here uses silicone oil; the sliding ring 8 consists of two parts (please refer to the attached Figure 4 ), and the two parts of the slip ring 8 are connected by bolts.

[0022] Please refer to Figure 3 , Figure 5 and Figure 8 The detection component includes: an elastic concave ring 10, which is fixed to the connecting column 4. The elastic concave ring 10 and the connecting column 4 are jointly fixed with a flexible ring piece 11. The fixed connection between the flexible ring piece 11 and the connecting column 4 is located between the elastic concave ring 10 and the mounting column 3. The connecting column 4, the elastic concave ring 10 and the flexible ring piece 11 together constitute a detection cavity 111; a friction ring 12, which is slidably and rotatably connected in the damping shell 2, and there is friction between the two. The mounting column 3 and the connecting column 4 are both fixed with a limiting ring 121, and the limiting ring 121 is used to limit the moving distance of the friction ring 12. The side of the friction ring 12 close to the elastic concave ring 10 is fixed with an extrusion frame 13, and the extrusion frame 13 is used to extrude the elastic concave ring 10; a transmission component is arranged in the mounting column 3, and is used to control the flow area of ​​the slow flow hole 801.

[0023] In the above scheme, the purpose is to use the time interval of the elastic concave ring 10 recovering after deformation to detect the movement frequency of the wire, and adjust the flow area of ​​the slow flow hole 801 accordingly, so as to change the damping coefficient of the damping connection unit; the elastic concave ring 10 is made of elastic rubber material, and the elastic concave ring 10 is in a stress-free state at the beginning, and the elastic concave ring 10 can restore its original state under the action of its own elasticity after being squeezed and deformed by the squeezing frame 13; the flexible ring piece 11 is a flexible material that cannot be stretched (polyester film is selected here), and the middle part of the flexible ring piece 11 is in a bent state at the beginning, and the volume of the detection cavity 111 is the largest at this time; the spacing between the two limit rings 121 is equal to twice the thickness of the friction ring 12.

[0024] Please refer to Figure 4-Figure 6 The transmission assembly includes: an elastic tube 14, which is fixed in the connecting column 4, and the two together form a temporary storage chamber 141, and the temporary storage chamber 141 is connected to the detection chamber 111; a transfer ring 15, which is sealed and rotatably connected between the mounting column 3 and the connecting column 4, and the transfer ring 15 is provided with a transfer through hole 151, and a connecting flow channel 302 is provided in the mounting column 3, and the transfer through hole 151 is used to connect the connecting flow channel 302 with the temporary storage chamber 141; an elastic liquid capsule 16, which is fixed between the sliding ring 8 and the shielding ring 9, and the elastic liquid capsule 16 is connected to the connecting flow channel 302, and the detection chamber 111, the temporary storage chamber 141, the transfer through hole 151, the connecting flow channel 302 and the elastic liquid capsule 16 are all filled with transmission medium; an elastic rope 17, which is fixed between the sliding ring 8 and the shielding ring 9; the elastic coefficient of the elastic tube 14 is greater than the elastic coefficient of the elastic rope 17.

[0025] In the above scheme, the transmission medium is used to convert the change of the wire movement frequency measured by the detection component into the change of the flow area of ​​the slow flow hole 801; the elastic tube 14 is made of elastic rubber, and there is a cylindrical cavity at the position where the elastic tube 14 is fixed in the connecting column 4, and the diameter of the cylindrical cavity is larger than the outer diameter of the elastic tube 14; the transmission medium is a liquid with a small viscosity-temperature coefficient, and silicone oil is selected here; the elastic liquid capsule 16 and the elastic rope 17 are both located in the arc space formed by the sliding ring 8 and the shielding ring 9 (please refer to the attached Figure 6 ), so that the elastic liquid capsule 16 expands and pushes the shielding ring 9 to rotate counterclockwise (the rotation angle of this article is attached Figure 1 (in the viewing direction of the right view), the shielding ring 9 will pull the elastic rope 17 to stretch.

[0026] Please refer to Figure 7-Figure 9The transit ring 15 is fixedly connected with a one-way piece 18, and the one-way piece 18 is made of elastic material. The mounting column 3 is provided with a plurality of limiting grooves 181 distributed in an annular shape, and the limiting grooves 181 are used to limit the one-way piece 18 in one direction; a convex column 19 is fixedly connected to the side of the transit ring 15 away from its central axis, and the friction ring 12 is provided with a guide groove 191, and the convex column 19 slides in the guide groove 191; two elastic sheets 20 are fixedly connected to the transit through hole 151, and the elastic sheets 20 are used to change the flow area of ​​the transit through hole 151, and the opposite sides of the two elastic sheets 20 are provided with flow control notches 201.

[0027] In the above scheme, the one-way rotation of the transfer ring 15 is used to change the connection state of the transfer through hole 151, the connecting flow channel 302 and the temporary storage chamber 141; the one-way sheet 18 is made of elastic metal material, and the number of the one-way sheets 18 can be adjusted according to actual conditions. The one-way sheets 18 in this article are six distributed in an annular shape; the number of the limiting grooves 181 can be adjusted according to actual conditions, so that each time the friction ring 12 guides the boss 19 and the transfer ring 15 to rotate through the guide groove 191, the one-way sheet 18 can enter the adjacent limiting groove 181; the elastic The sheet 20 is made of elastic silicone material, and the position where the two elastic sheets 20 contact each other is on the right side of the elastic sheet 20. During the period when the two elastic sheets 20 contact each other, the two flow control notches 201 thereon form a through hole for silicone oil to flow. When the silicone oil flows to the right in the transfer through hole 151, it can push the two elastic sheets 20 to deform, causing the two elastic sheets 20 to lose contact, thereby making the flow area of ​​the silicone oil when flowing to the right in the transfer through hole 151 larger than the flow area when flowing to the left (that is, the flow area of ​​the through hole formed by the two flow control notches 201).

[0028] The working principle of the above scheme is as follows: when installing the device, the drone carries the device and moves it to the top of the two wires to be installed (this article takes the installation of the device on two horizontally arranged wires as an example for explanation), and then the drone carries the device downward, so that the left and right electric claws 6 are respectively set up on the adjacent wires, and then the staff remotely controls the electric claws 6 to clamp and fix the wires, and withdraws the drone, thereby completing the installation of the device.

[0029] When the wire moves due to the influence of wind, the distance between the two wires changes frequently due to the movement, so that the overall length of the device changes with the distance between the two wires. When the gap between the two wires decreases (hereinafter, a group of damping connection units on the right side will be used as an example for explanation), the wire drives the connecting column 4 to move through the electric clamp 6 and the middle block 5, and the middle block 5 slides to the left relative to the damping shell 2, and the connecting column 4 drives the mounting column 3, the sliding ring 8, the elastic concave ring 10, the flexible ring sheet 11, the limit ring 121 and the transfer ring 15 to move to the left together; when the sliding ring 8 moves to the left, the spring of the sliding ring 8 is compressed, and the silicone oil in the damping chamber 301 flows through the slow flow hole 801, and the viscous resistance generated when the silicone oil flows through the slow flow hole 801 consumes the energy of the wire movement (later, when the sliding ring 8 moves to the right, the spring of the sliding ring 8 is first restored and then stretched, and the viscous resistance encountered by the silicone oil when passing through the slow flow hole 801 is also used to consume the energy of the wire movement).

[0030] When the elastic concave ring 10 moves to the left, since the friction ring 12 and the extrusion frame 13 are in a stationary state, the distance between the elastic concave ring 10 and the friction ring 12 gradually decreases, so that the elastic concave ring 10 is squeezed by the extrusion frame 13 and deformed, and the elastic concave ring 10 changes from a concave state to the left to a concave state to the right. At the same time, the elastic concave ring 10 pulls the flexible ring sheet 11 to stretch, and the friction ring 12 contacts the right limit ring 121. The connecting column 4 drives the friction ring 12 through the right limit ring 121. 12 and the extrusion frame 13 move left together; while the distance between the elastic concave ring 10 and the friction ring 12 gradually decreases, the connecting column 4 drives the transit ring 15 to move left, and the transit ring 15 is kept stationary with the connecting column 4 by the unidirectional limiting effect of the one-way sheet 18, and the transit ring 15 drives the convex column 19 to slide in the adjacent guide groove 191, and squeezes the friction ring 12 to rotate counterclockwise until the friction ring 12 contacts the limiting ring 121 on the right, and the convex column 19 moves to the end of the left side of the adjacent guide groove 191.

[0031] During the extension of the flexible ring sheet 11, the flexible ring sheet 11 squeezes the silicone oil in the detection chamber 111 into the elastic tube 14. At this time, due to the small flow area of ​​the silicone oil when it flows to the left in the transfer through hole 151, the speed of the silicone oil flowing to the left through the transfer through hole 151 is lower than the speed of the volume change of the detection chamber 111, so that the volume of the silicone oil in the temporary storage chamber 141 increases, and the elastic tube 14 expands toward the circumference. The silicone oil in the temporary storage chamber 141 enters the transfer through hole 151 and flows to the left. The silicone oil in the transfer through hole 151 passes through the two flow control notches. The liquid flows slowly into the connecting channel 302 through the through hole formed by 201, and enters the elastic liquid bag 16 along the connecting channel 302, so that the elastic liquid bag 16 expands and deforms. The elastic liquid bag 16 pushes the shielding ring 9 to rotate slowly counterclockwise and stretches the elastic rope 17. The connecting groove 901 is gradually misaligned with the adjacent slow flow hole 801. At the same time, the shielding ring 9 gradually blocks the adjacent slow flow hole 801, so that the flow area of ​​the slow flow hole 801 gradually decreases. As the flow area of ​​the slow flow hole 801 decreases, the damping coefficient of the device increases.

[0032] When the distance between the two wires increases due to movement, the wire drives the connecting column 4 to move rightward through the electric claw 6 and the middle connecting block 5. The friction ring 12 and the extrusion frame 13 move rightward later than the connecting column 4 due to the friction force. The friction ring 12 loses contact with the limit ring 121 on the right side. The transfer ring 15 moves rightward relative to the friction ring 12. The protruding column 19 slides along the adjacent guide groove 191, so that the protruding column 19 drives the transfer ring 15 to rotate counterclockwise (the transfer ring 15 drives the one-way plate 18 to rotate, so that the one-way plate 18 loses contact with the adjacent limit groove 181, and the one-way plate 18 deformation), the transit ring 15 drives the transit through hole 151 to rotate, so that the flow area between the transit through hole 151 and the connecting flow channel 302 gradually decreases, until the friction ring 12 contacts the limiting ring 121 on the left, the protruding column 19 slides to the end of the right side of the adjacent guide groove 191, at which time the transit ring 15 stops rotating (the one-way plate 18 restores its shape under its own elasticity and enters the adjacent limiting groove 181), the transit through hole 151 and the connecting flow channel 302 are completely misaligned, and the connecting flow channel 302 is disconnected from the temporary storage chamber 141.

[0033] When the connecting column 4 moves to the right, the connecting column 4 drives the elastic concave ring 10 to move to the right, and the distance between the elastic concave ring 10 and the friction ring 12 gradually increases. The elastic concave ring 10 gradually recovers under the action of its own elasticity until the friction ring 12 contacts the limit ring 121 on the left, and the elastic concave ring 10 is completely recovered. At this time, there is extra space in the detection cavity 111 (that is, the flexible ring sheet 11 is not fully extended), and the pressure in the temporary storage cavity 141 is greater than the pressure in the detection cavity 111. The silicone oil in the temporary storage cavity 141 gradually flows into the detection cavity 111, and the shape of the elastic tube 14 gradually recovers. Finally, when the elastic tube 14 recovers, the volume of the silicone oil in the detection cavity 111 is smaller than the initial volume. The flow area of ​​the slow flow hole 801 is controlled according to the volume of silicone oil flowing into the elastic liquid capsule 16 within the time interval after the elastic concave ring 10 is deformed and restored. That is, the greater the frequency of the wire movement, the smaller the time interval after the elastic concave ring 10 is deformed and restored, and the smaller the volume of silicone oil flowing into the elastic liquid capsule 16 within the above time interval, so that the change in the flow area of ​​the slow flow hole 801 is smaller, that is, the final flow area of ​​the slow flow hole 801 is larger. Conversely, the smaller the frequency of the wire movement, the greater the change in the flow area of ​​the slow flow hole 801, that is, the final flow area of ​​the slow flow hole 801 is smaller, thereby achieving the purpose of controlling the damping coefficient according to the frequency of the wire movement.

[0034] After the conductor performs a reciprocating motion, the intermediate ring 15 temporarily separates the connecting flow channel 302 from the temporary storage chamber 141. As the conductor continues to move, the sliding ring 8 continues to slide in the damping chamber 301 and consumes the energy of the conductor movement by utilizing the viscous resistance of the silicone oil passing through the slow flow hole 801. The intermediate ring 15 is driven by the friction ring 12 to intermittently rotate counterclockwise. During this process, the flow area of ​​the slow flow hole 801 remains unchanged. At the same time, the elastic concave ring 10 and the flexible ring sheet 11 reciprocate and deform. The elastic cylinder 14 is in the position, and the elastic cylinder 14 is reciprocated and then reset, until the transfer through hole 151 reconnects the connecting flow channel 302 with the temporary storage chamber 141. At this time, the shape of the elastic concave ring 10 has just been restored, and the shielding ring 9 rotates clockwise under the action of the elastic rope 17 and squeezes the elastic liquid capsule 16. The pressure of the silicone oil in the elastic liquid capsule 16 is greater than the pressure of the silicone oil in the temporary storage chamber 141 and the detection chamber 111. At this time, the silicone oil in the elastic liquid capsule 16 quickly passes through the connecting flow channel 302 into the transfer through hole 151, and the silicone oil in the transfer through hole 151 The silicone oil squeezes the two elastic sheets 20 to deform, causing the two elastic sheets 20 to lose contact, and at the same time the flow area of ​​the transfer through hole 151 increases, and then the silicone oil passes through the temporary storage cavity 141 and enters the detection cavity 111, so that the flexible ring sheet 11 gradually recovers, and finally the elastic liquid capsule 16 and the flexible ring sheet 11 recover their shapes, the shielding ring 9 resets relative to the sliding ring 8, and the connecting groove 901 corresponds to the adjacent slow flow hole 801 again, and the flow area of ​​the slow flow hole 801 reaches the maximum, and then when the movement direction of the connecting column 4 changes again, the above-mentioned steps of restoring after the elastic concave ring 10 is deformed are repeated to adjust the flow area of ​​the slow flow hole 801, so as to achieve the purpose of adaptively adjusting the damping coefficient; during the above-mentioned wire movement, even when the device is compressed to the shortest state, a safe gap can be maintained between two adjacent wires, and finally when the wire stops moving, the sliding ring 8 resets under the action of the spring thereon, and the sliding ring 8 drives the mounting column 3, the connecting column 4, the middle connecting block 5, the electric claw 6 and the limit ring 121 to reset together.
