Description

Technical Field

[0001] The present invention relates to the technical field of power transmission, and in particular to a power transmission dynamic compensation system. Background Art

[0002] Power transmission refers to the process of efficiently and stably transmitting the electricity generated by power plants to power-consuming areas through transmission lines, substations and other facilities. In modern energy systems, power transmission is a key link connecting the power generation end and the power consumption end. Its main purpose is to ensure the reliable supply of electricity during long-distance transmission and meet the electricity needs of different regions and different users.

[0003] Chinese patent (publication number: CN118783333A), the solution specifically includes a utility pole, a fixing frame, a supporting mechanism 1, a supporting mechanism 2 and a traction mechanism. The two supporting mechanisms 1 can be detachably mounted on the fixing frame. The supporting mechanism 1 is used to fix and support the cable. Among them, the supporting mechanism 1 includes a limiting component and a clamping component. The limiting component is used to limit the swing amplitude of the cable, and the clamping component is used to clamp and fix the cable. The supporting mechanism 2 can be detachably mounted in the center of the fixing frame. The supporting mechanism 2 is used to fix and support the cable. The traction mechanism adjusts the distance between multiple cables when the cable is swinging. Through the above technical solution, the problem of the existing power regulation mechanism for power transmission in the prior art being difficult to prevent the cable from touching the line in windy weather and the problem of insulation layer damage after the cable is fixed is solved.

[0004] When existing power transmission lines are affected by wind, the cables will swing, and the fixed support structure is difficult to make corresponding adjustments according to the swing of the cables.

[0018] The following will provide a clear and complete description of the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

[0019] See also Figures 1 to 10 The present invention provides a technical solution: a power transmission dynamic compensation system, comprising a hinge frame 1 arranged on a concrete pole, the hinge frame 1 being provided with a plurality of insulator strings 3 and a line clamp 4 for supporting and fixing cables 2, and the hinge frame 1 being provided with a displacement mechanism for adjusting the spacing between adjacent cables 2 according to wind factors and dynamically changing the position of the stress concentration point of the cables 2; The displacement mechanism includes a self-clamping assembly that supports the cable 2 synchronously with the line clamp 4. The anchor frame 1 is provided with a transverse seat 9 that is fixedly connected to the insulator string 3. The end of the insulator string 3 away from the transverse seat 9 is fixedly connected to the line clamp 4. A group of end sealing seats 12 are bolted to both ends of the anchor frame 1. The end sealing seats 12 are provided with a fixed displacement assembly for adjusting the horizontal spacing between the line clamp 4 and the self-clamping assembly. The said anchor frame 1 is fixedly connected with a column seat 29, which includes an integrally formed inner chamber 31 for receiving oil. The anchor frame 1 is provided with a swing component for adjusting the horizontal and longitudinal spacing between two adjacent groups of transverse seats 9 according to the amount of oil in the inner chamber 31.

[0020] like Figure 1 、 Figure 2 、 Figure 9 and Figure 10 As shown, when the cable 2 is erected, the bracket 1 is fixedly connected to the concrete pole through an external bracket, and the cable 2 is supported and fixed to the bracket 1 by the line clamp 4. At the same time, an insulator string 3 is arranged between the line clamp 4 and the bracket 1 to improve the insulation. The cable 2 is synchronously supported by the self-clamping component. When the external wind force is strong, the cable 2 between the two groups of concrete poles will be driven to swing under the action of the strong wind force, and then the cable 2 will rub against the line clamp 4 when swinging. The stress concentration point during the swing is at the connection position between the cable 2 and the fixing part. The long-term friction at the fixed position will cause long-term wear of the same position of the cable 2, thereby reducing the service life of the cable 2 and further increasing the risk of cable 2 breakage, short circuit and other faults.

[0021] At the same time, by setting a self-clamping component that supports the cable 2 synchronously with the line clamp 4, the self-clamping component can move horizontally under the action of external wind force and driven by the fixed and movable component, that is, it can move along the laying direction of the cable 2, thereby dynamically changing the relative position of the self-clamping component and the cable 2, and the distance between the self-clamping component and the line clamp 4 is related to the wind force, so that when the wind force is different, the contact position of the self-clamping component and the cable 2 is different. Therefore, when there is natural wind force, by adjusting the distance between the self-clamping component and the line clamp 4, the stress concentration point position of the cable 2 at the swinging end is dynamically changed to avoid excessive wear of the cable 2 at the same position during the swinging process, thereby achieving the purpose of improving the service life of the cable 2.

[0022] It should be noted that when the wind direction is perpendicular to the laying direction of cable 2, the wind will generate horizontal loads on cable 2 and the suspended insulator string 3, causing cable 2 and insulator string 3 to swing in the direction of wind pressure. When the wind direction is parallel to the laying direction of cable 2, the wind mainly generates longitudinal force on cable 2, causing cable 2 to swing up and down. When the wind direction is at a certain angle to the laying direction of cable 2, the wind can be decomposed into two components: one parallel to the direction of cable 2, and the other perpendicular to the direction of cable 2. The vertical component is still the main swing factor. It is known that when there is a wind direction that is perpendicular to the laying direction of cable 2 or that is at a certain angle to the laying direction of cable 2, cable 2 will swing under the action of the wind.

[0023] Therefore, the fixed displacement component can dynamically adjust the position of the stress concentration point when the cable 2 swings according to the magnitude of the wind force, and the swing distance component can adaptively change the horizontal longitudinal spacing between the two groups of horizontal seats 9 when the angle between the wind direction and the laying direction of the cable 2 is small and the wind force is strong, thereby increasing the spacing between the two adjacent groups of cables 2.

[0024] Among them, when the wind direction is perpendicular to the laying direction of the cable 2, the cable 2 will swing in the direction of the wind pressure, forming a wind deviation angle. If the spacing between adjacent cables 2 is too small, the wind deviation may cause insufficient electrical clearance between the cables 2, thereby causing a discharge accident. Then, the spacing between the two groups of cables 2 is adjusted by the swing distance component according to the combination of wind force and wind direction factors to cope with extreme windy weather, avoid collision and interference between adjacent cables 2, and ensure a safe distance between cables 2 to avoid the occurrence of discharge accidents.

[0025] In one of the more preferred embodiments, the self-clamping assembly includes an upper clamping seat 5 and a lower clamping seat 6 which are sleeved on the cable 2, the upper clamping seat 5 and the lower clamping seat 6 are fixed with bolts, and the lower clamping seat 6 is fixedly connected to a guide column 7 at one end facing the line clamp 4; The line clamp 4 is fixedly connected to a positioning block 11, and the positioning block 11 is provided with a circular hole for the guide column 7 to slide through. The outer circumference of the guide column 7 is sleeved with a return spring 8, and the two ends of the return spring 8 are respectively fixedly connected to the positioning block 11 and the lower clamp seat 6.

[0026] A pull rope 14 is hung and fixed on the upper clamping seat 5, and the reset spring 8 is in a compressed deformation state in the initial state.

[0027] like Figures 1-4 As shown, the upper clamp seat 5 and the lower clamp seat 6 are fixedly connected by bolts, and the cable 2 is placed in the grooves of the two. The column groove formed by the two for the cable 2 to pass through is slightly larger than the diameter of the cable 2 to ensure that the upper clamp seat 5 and the lower clamp seat 6 can be smoothly displaced along the laying direction of the cable 2.

[0028] At the same time, the pull rope 14 is in a taut state in the initial state, and the reset spring 8 is in a compressed state. At this time, the distance between the upper clamp seat 5 and the lower clamp seat 6 and the line clamp 4 is the smallest. As the pull rope 14 is gradually released, the reset spring 8 has space to recover its deformation. Under the action of external wind force, the release amount of the pull rope 14 can be changed according to the size of the wind force, thereby determining the recovery deformation amount of the reset spring 8, and in the process of the reset spring 8 recovering its deformation, the horizontal distance between the upper clamp seat 5 and the lower clamp seat 6 and the line clamp 4 is gradually increased.

[0029] It should be noted that in actual use, by fixing the guide column 7 on the lower clamp seat 6 and driving the guide column 7 to slide through the positioning block 11 fixed on the line clamp 4, the stability of the upper clamp seat 5 and the lower clamp seat 6 during horizontal movement can be ensured. At the same time, since the cable 2 swings due to wind factors, the cable 2 may be driven to squeeze the upper clamp seat 5 and the lower clamp seat 6 during the swinging process, so as to cause the distance between the upper clamp seat 5 and the lower clamp seat 6 and the line clamp 4 to change repeatedly within a smaller range. However, the stress concentration point at the end of the cable 2 when swinging is at the connection position with the upper clamp seat 5 and the lower clamp seat 6, and the stress concentration point of the cable 2 can be dynamically changed by changing the position of the upper clamp seat 5 and the lower clamp seat 6 to avoid excessive wear at a certain position on the cable 2, thereby achieving the purpose of increasing the service life of the cable 2.

[0030] On the basis of the embodiment of the self-clamping assembly, the fixed-movement assembly includes a wind wheel 17 that rotates on a fixed axis on the end sealing seat 12, and a I-shaped cylinder 13 is provided on one side of the wind wheel 17. A pull rope 14 is wound on the I-shaped cylinder 13, and one end of the pull rope 14 is fixedly connected to the I-shaped cylinder 13, and the end of the pull rope 14 away from the I-shaped cylinder 13 is hung and fixed on the upper clamping seat 5; The I-shaped cylinder 13 rotates on the end sealing seat 12 with a fixed axis, and a driven gear 15 is coaxially fixed on the I-shaped cylinder 13 . The driven gear 15 is meshed with a driving gear 16 . The driving gear 16 and the wind wheel 17 are coaxially fixed.

[0031] like Figure 1 、 Figure 5 and Figure 6 As shown, under the action of external wind force, the wind wheel 17 can rotate a certain angle in the horizontal direction, and the wind wheel 17 rotates in the same direction under wind forces of different directions. When the wind wheel 17 rotates, it can drive the driving gear 16 fixed coaxially with the wind wheel 17 to rotate synchronously, wherein the driving gear 16 is meshed with the driven gear 15, and by controlling the meshing ratio between the driving gear 16 and the driven gear 15, the driven gear 15 and the I-shaped cylinder 13 are prompted to rotate more circles in the horizontal direction.

[0032] At the same time, when the I-shaped cylinder 13 rotates, the wound pull rope 14 can be gradually released, and when the release amount of the pull rope 14 is related to the rotation angle of the wind wheel 17, at the same time, when the pull rope 14 is released, the reset spring 8 can gradually restore the deformation, and the recovery deformation of the reset spring 8 is related to the release amount of the pull rope 14, thereby causing the distance between the upper clamp seat 5 and the lower clamp seat 6 and the line clamp 4 to change, and the change in the distance is related to the wind force, so that under different wind forces, the relative positions of the upper clamp seat 5 and the lower clamp seat 6 and the cable 2 can be driven to be different, so as to achieve the purpose of changing the stress concentration point of the cable 2.

[0033] It should be noted that the end sealing seat 12 is provided with a coil spring that drives the I-shaped cylinder 13 to return to its original state. The coil spring is an existing device and a technical means well known to those skilled in the art, so it is not shown in the figure. When the wind wheel 17 is subjected to external wind force, it can drive the driven gear 15 to rotate, thereby causing the coil spring to deform. When the external wind force becomes smaller or disappears, it can cause the I-shaped cylinder 13 to gradually return to its original state and rewind the rope 14, so that the tension of the rope 14 causes both the upper clamping seat 5 and the lower clamping seat 6 to return to their initial positions, and causes the reset spring 8 to return to the compressed deformation amount in the initial state again.

[0034] Based on the embodiment of the fixed displacement assembly, the swing assembly includes an axis head pressure plate 30 that is in sliding contact with the inner wall of the column head seat 29, and a center column 33 is fixedly connected to the axis head pressure plate 30. The top end of the center column 33 slides through the column head seat 29 and the bracket frame 1 and rotates on a fixed axis with multiple sets of connecting rods 35. The end of the connecting rod 35 away from the center column 33 rotates on a fixed axis on the horizontal seat 9, and the bracket frame 1 is provided with a horizontal slide groove 10 for the horizontal seat 9 to slide in the horizontal and longitudinal directions. The outer circumference of the center column 33 is sleeved with a give-way spring 34, and the two ends of the give-way spring 34 are respectively fixedly connected to the shaft head pressure plate 30 and the inner wall of the column head seat 29. The inner wall of the column head seat 29 is fixedly connected with a conical ring 32 that limits the displacement of the shaft head pressure plate 30.

[0035] The swing assembly also includes a hollow mounting cylinder 18 fixedly connected to the end seal seat 12. An air duct 24 for natural air circulation is fixedly passed through the hollow mounting cylinder 18. Multiple groups of synchronously deflected triangular sealing seats 19 are arranged in the hollow mounting cylinder 18. Adjacent triangular sealing seats 19 are in sliding contact with each other, and a special-shaped cavity for gas circulation is formed between the multiple groups of triangular sealing seats 19. The plurality of triangular sealing seats 19 are provided with micro-path channels 20 for gas communication with the special-shaped cavities. The hollow mounting cylinder 18 is fixedly connected with an annular pipe 25. The annular pipe 25 is in gas communication with the plurality of micro-path channels 20. The annular pipe 25 is fixedly passed through the column head seat 29 and is in gas communication with the inner chamber 31. The hollow mounting cylinder 18 is provided with an internal flow component for adjusting the cross-sectional size of the special-shaped cavity.

[0036] like Figure 1 、 Figure 5 、 Figure 6 、 Figure 8 、 Figure 9 and Figure 10As shown, when the external wind force is strong, the internal flow components can drive multiple groups of triangular seals 19 to deflect synchronously in the hollow mounting tube 18, thereby changing the cross-sectional size of the special-shaped cavity composed of the multiple groups of hollow mounting tubes 18. According to the Venturi effect, when the fluid passes through the narrowed channel, the flow rate of the fluid will increase, and according to the Bernoulli effect, since the sum of its kinetic energy, potential energy and pressure energy remains unchanged, when the air passes through the special-shaped cavity, its flow rate increases, and low pressure will be generated here.

[0037] At the same time, the triangular seal seat 19 is gas-connected with multiple groups of micro-channels 20, and the micro-channels 20 are connected between the annular pipe 25 and the inner chamber 31. Therefore, when the natural wind perpendicular to the laying direction of the cable 2 or at a certain angle flows through the air duct pipe 24, it can cause a low pressure phenomenon to occur at the special-shaped cavity, and the low pressure phenomenon is alleviated by the oil in the inner chamber 31. Among them, the annular pipe 25 is connected with the inner chamber 31 through the connecting pipe, and then when the gas circulates in the air duct pipe 24, it can drive the oil in the inner chamber 31 to gradually enter the connecting pipe, thereby reducing the amount of oil in the inner chamber 31.

[0038] Among them, when the oil in the inner chamber 31 decreases, low pressure occurs therein, which prompts the shaft head pressure plate 30 to move downward and drives the give way spring 34 to stretch and deform. A center column 33 is fixedly provided on the shaft head pressure plate 30, which can drive the center column 33 to move downward through the reduction of the inner chamber 31. At the same time, the center column 33 is connected to the transverse seat 9 through the connecting rod 35, and when the center column 33 moves downward, the transverse seat 9 can be pushed to move horizontally through the connecting rod 35, thereby increasing the horizontal spacing between the two groups of transverse seats 9 and the cables 2 thereunder, so as to effectively reduce the influence of the wind deviation angle on the electrical gap, ensure the safe distance between the cables 2, and reduce the risk of discharge accidents.

[0039] It should be noted that a conical ring 32 is provided in the column head seat 29. The conical ring 32 can limit the descending distance of the shaft head pressure plate 30, thereby preventing excessive escape of oil in the inner chamber 31. When there is a continuous strong wind force and the wind direction is perpendicular to the laying direction of the cable 2 or has a certain angle with the laying direction of the cable 2, the cross-sectional size of the special-shaped cavity is driven by the internal flow component and is smaller than the cross-sectional size of the air duct tube 24, thereby prompting the oil in the inner chamber 31 to enter the connecting pipe. By providing the conical ring 32, the shaft head pressure plate 30 can not continue to move downward when it conflicts with the conical ring 32, and the oil in the connecting pipe is difficult to continue to move along the connecting pipe, thereby preventing the oil from escaping.

[0040] At the same time, when the external wind force disappears, the give way spring 34 can restore its deformation and drive the shaft head pressure plate 30 and the give way spring 34 to move upward, so as to prompt the two sets of horizontal seats 9 to restore their initial spacing. In the process of restoring the deformation of the give way spring 34, the oil that previously flowed to the connecting pipe can be continued to flow back into the inner chamber 31 to ensure the continuous use of the oil in the inner chamber 31.

[0041] Among them, only when the wind direction is perpendicular to the cable 2 or presents a certain angle with the laying direction of the cable 2, and when the wind force is strong, the external natural wind can enter the air duct tube 24 while maintaining a high flow rate, and when the wind force is strong, it can change the cross-sectional size of the special-shaped cavity, thereby reducing the amount of oil in the inner chamber 31, so as to achieve the purpose of changing the distance between the two groups of horizontal seats 9 and the cables 2 thereon. When the wind force is small or the wind direction is different from the setting, the distance between the two groups of horizontal seats 9 will not be changed. The reason is: when the wind direction is parallel to the laying direction of the cable 2, the vertical component of the force acting on the cable 2 is small, and the swing amount of the cable 2 is small. At the same time, when the external wind force is small, the swing amount of the cable 2 is also small. Therefore, in this case, the position change of the horizontal seat 9 will not be triggered.

[0042] Based on the embodiment of the swing distance assembly, the internal flow assembly includes a groove body 1 provided on a hollow mounting cylinder 18 and used for sliding connection of multiple sets of triangular sealing seats 19. The inner wall of the hollow mounting cylinder 18 is provided with an aligned circular ring 21 for fixed axis rotation. The multiple sets of triangular sealing seats 19 are fixedly connected to a limit pin 22 on one side facing the aligned circular ring 21. The aligned circular ring 21 is provided with a limit groove 23 for sliding connection of the limit pin 22. The outer circumference of the co-ordination ring 21 is fixedly connected to an axial column 26, and the hollow mounting cylinder 18 is provided with an arc-shaped groove for the axial column 26 to pass through; An open cylinder 27 is coaxially fixed to the wind wheel 17 . A V-shaped guide groove 28 is provided on the open cylinder 27 for the axial column 26 to slide through. The V-shaped guide groove 28 includes an integrally formed flat groove portion and a spiral bevel groove portion.

[0043] like Figure 5 and Figure 6 As shown, when the wind wheel 17 rotates a certain angle under the action of external wind force, it can drive the open cylinder 27 coaxially arranged therewith to rotate synchronously. When the open cylinder 27 rotates, the V-shaped guide groove 28 opened thereon can be driven to rotate synchronously, thereby changing the relative position of the V-shaped guide groove 28 and the axial column 26. When the wind wheel 17 and the open cylinder 27 initially rotate, the axial column 26 slides in the flat groove part, and the height of the axial column 26 remains unchanged at this time, so that the co-positioned ring 21 fixedly connected to the axial column 26 will not rotate at this time.

[0044] Among them, as the open cylinder 27 continues to rotate, the axial column 26 enters the spiral bevel portion, thereby causing the height of the axial column 26 to change, so as to cause the axial column 26 and the isotropic ring 21 fixedly connected thereto to rotate vertically by a certain angle. At the same time, the limit pin 22 fixedly arranged on the triangular sealing seat 19 is slidably connected to the isotropic ring 21 through the limit groove 23. Therefore, when the isotropic ring 21 rotates, the limit pin 22 and the limit groove 23 can drive multiple groups of triangular sealing seats 19 to deflect synchronously to change the cross-sectional size of the special-shaped cavity composed of multiple groups of triangular sealing seats 19, and the gas between the isotropic ring 21 and the air duct pipe 24 is connected and in sliding contact, so that the natural air from the outside can flow through the special-shaped cavity through one port of the air duct pipe 24 and flow out from the other port of the air duct pipe 24.

[0045] It should be noted that only when the wind force is strong enough to drive the wind wheel 17 and the open cylinder 27 to rotate, and the axial column 26 is caused to correspond to the spiral bevel portion, will the axial column 26 and the isotropic ring 21 be used to drive the multiple groups of triangular sealing seats 19 to deflect, thereby achieving the purpose of changing the special-shaped cavity. Therefore, when the wind force is relatively small, the cross-sectional size of the special-shaped cavity formed between the multiple groups of triangular sealing seats 19 is larger than the cross-sectional size of the air duct tube 24, thereby driving the amount of oil in the inner chamber 31 to decrease, thereby not changing the horizontal spacing between the two groups of horizontal seats 9 and the cables 2 thereon.

[0046] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
