Description

Technical Field

[0001] This invention relates to the field of power transmission and distribution line fittings technology, specifically to an adaptive voltage equalization transformer street code. Background Technology

[0002] Variable displacement clamps are important hardware used to fix and support conductors in power transmission lines. Their performance directly affects the safety and service life of the line. At present, the mainstream variable displacement clamps on the market generally adopt a rigid clamp structure when fixing conductors, that is, to achieve the clamping and fixing of conductors by means of metal stamping or casting parts and U-bolts.

[0003] However, this traditional rigid fixed structure has the following inherent drawbacks:

[0004] The implicit attenuation of clamping force caused by dynamic loads cannot be quantified and displayed, ultimately leading to a lack of forward-looking basis for operation and maintenance decisions. Specifically, under dynamic operating conditions such as wind vibration and temperature difference changes, the continuous micro-movement and thermal expansion and contraction of the conductor will cause stress relaxation in the fastening system, resulting in irreversible attenuation and implicit drift of the clamping force. Traditional rigid structures cannot provide real-time and intuitive feedback on the clamping force status while suppressing the attenuation of clamping force. This makes it difficult to capture such implicit changes during routine inspections. The hidden dangers accumulate over time and may eventually lead to serious accidents such as conductor wear or even strand breakage.

[0005] Therefore, there is an urgent need for an integrated street code solution that can suppress the attenuation of clamping force while providing real-time and intuitive feedback on its status. Summary of the Invention

[0006] In view of the above-mentioned shortcomings of the existing technology, the present invention provides an adaptive voltage equalization shift street code, which can effectively solve the problems of the existing technology.

[0007] To achieve the above objectives, the present invention provides the following technical solution:

[0008] This invention provides an adaptive voltage equalization displacement street code, including a fixed block, a limiting groove for accommodating a wire and a pressure cover for sealing the limiting groove in the fixed block, an adjusting screw is movably mounted on the pressure cover by a thread, a clamping block for clamping the wire is provided at one end of the adjusting screw, protrusions are fixedly mounted on the top and bottom of the clamping block, and a connecting block is movably mounted on the fixed block at the position corresponding to the protrusions. When the pressure cover and the fixed block are engaged, the protrusions and the connecting block are engaged and connected, and a damping indicator component is connected to one side of the connecting block for providing damping locking and visually indicating the clamping status.

[0009] Furthermore, the top and bottom of the limiting groove are provided with a slot 1. The pressure cover is engaged with the slot 1 by a locking block fixedly installed on its top and bottom. A locking bolt is fixedly installed on the top of the fixing block, and the locking block is threadedly connected to the locking bolt by a locking groove opened on its top.

[0010] Furthermore, the top and bottom of the limiting groove are provided with a second slot and a rectangular groove. The second slot is used to guide the movement of the protrusion. The connecting block is movably installed in the rectangular groove. The connecting block is provided with a locking groove that matches the protrusion.

[0011] Furthermore, the damping indicator assembly includes a fixed tube, a piston, and a connecting rod. The fixed tube is fixedly installed inside the fixed block, and the piston is movably installed inside the fixed tube. The piston is fixedly connected to the connecting block through the connecting rod. A reset plate is fixedly installed on the connecting rod, and the reset plate is connected to the inner wall of the fixed block through a reset spring. A threaded exhaust pipe is provided at the end of the fixed tube away from the connecting rod, and a cap is threaded on the exhaust pipe.

[0012] Furthermore, when the rotating adjusting screw drives the clamping block to move toward the wire, the clamping block drives the connecting rod and piston to move inside the fixed tube through the protrusion and connecting block. By selectively installing or removing the cap on the exhaust pipe, the air cushion damping that hinders the movement of the clamping block is correspondingly established or released.

[0013] Furthermore, the clamping block has an arc-shaped clamping groove on the side near the conductor, and a clamping pad with an uneven surface is fixed on the inner wall of the limiting groove. Through the coordinated cooperation of the arc-shaped clamping groove and the clamping pad, a surface contact clamping of the conductor is formed.

[0014] Furthermore, the damping indicator assembly also includes an indicator block, which is fixedly connected to a connecting block located at the top of the limiting groove. The top of the fixed block has a through groove that communicates with the rectangular groove. The indicator block is movably disposed in the through groove, and a scale for marking the clamping state is provided on one side of the through groove.

[0015] Furthermore, when the clamping block moves toward the wire, it drives the indicator block to move within the through slot via the connecting block. When the clamping force loosens, the reset spring pushes the reset plate and connecting rod to reset, thereby causing the indicator block to move back within the through slot.

[0016] Furthermore, the scale is arranged with green, yellow and red areas along the length of the through groove. The length range of the green area corresponds to the rated working range of the clamping force, the length range of the yellow area corresponds to the warning range of the clamping force, and the length range of the red area corresponds to the range below the safe threshold of the clamping force.

[0017] Furthermore, the movement of the indicator block within the through slot corresponds synchronously with the clamping stroke of the clamping block. When the indicator block moves to the green area of ​​the scale, it indicates that the clamping force has reached the rated working range. When the indicator block moves back to the yellow area of ​​the scale due to the loosening of the clamping force, it indicates that preventive maintenance is required. When the indicator block moves back to the red area, it indicates that the clamping force has fallen below the safety threshold and needs to be adjusted immediately.

[0018] The technical solution provided by this invention has the following advantages compared with the prior art:

[0019] This invention constructs an intelligent clamping system that integrates dynamic maintenance of clamping force and visualization of its status by setting a damping indicator component. On the one hand, the damping indicator component effectively absorbs and buffers dynamic loads such as wind vibration by utilizing the air cushion damping effect, significantly suppressing the clamping force attenuation caused by vibration in traditional structures and solving the problem of uncontrollable clamping force. On the other hand, through the indicator block and scale scale linked with the clamping block, real-time visual feedback of the clamping force status is realized, enabling maintenance personnel to remotely and intuitively judge the clamping force level, fundamentally solving the hidden danger of invisible clamping force.

[0033] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0034] The present invention will be further described below with reference to embodiments.

[0035] Example 1

[0036] Reference Figures 1-6 This is the first embodiment of the present invention, which provides an adaptive voltage equalization and displacement street code, including a fixing block 1. The fixing block 1 is provided with a limiting groove 11 for accommodating the conductor and a pressure cover 12 for sealing the limiting groove 11. A vertical block is fixedly installed at the bottom of the fixing block 1, and a connecting plate is fixedly installed at the bottom of the vertical block. The connecting plate has through holes for installing bolts. When installing the street code, the connecting plate is first fixed to the crossarm of the utility pole or the wall of a street building with bolts to complete the basic installation of the street code body. Then, the conductor to be fixed is placed in the limiting groove 11 of the fixing block 1, and the pressure cover 12 is connected to the fixing block 1 to complete the initial positioning of the conductor.

[0037] An adjusting screw 13 is movably mounted on the pressure cap 12 via a thread. One end of the adjusting screw 13 is provided with a clamping block 14 for clamping the wire. Both the top and bottom of the clamping block 14 are fixedly mounted with protrusions 141. A connecting block 15 is movably mounted on the fixing block 1 at the position corresponding to the protrusions 141. When the pressure cap 12 is engaged with the fixing block 1, the protrusions 141 and the connecting block 15 are engaged and connected. A damping indicator component 2 is connected to one side of the connecting block 15 to provide damping locking and visual indication of the clamping status.

[0038] After the pressure cap 12 is installed, rotate the adjusting screw 13 to drive the clamping block 14 to move towards the wire. At this time, as the adjusting screw 13 is continuously tightened, the clamping block 14 and the inner wall of the limiting groove 11 clamp the wire together. At the same time, the damping indicator component 2 is driven to enter the working state through the connecting block 15, forming a clamping system with dynamic stability function.

[0039] The clamping block 14 has an arc-shaped clamping groove 142 on the side near the conductor. The inner wall of the limiting groove 11 is fixed with a clamping pad 114 whose surface has been treated with concave and convex surfaces. Through the coordinated cooperation of the arc-shaped clamping groove 142 and the clamping pad 114, a surface contact clamping of the conductor is formed.

[0040] The arc-shaped clamping groove 142 and the clamping pad 114 with concave and convex textures form corresponding curved clamping surfaces, which can adaptively wrap wires of different diameters, transforming traditional point contact or line contact into uniformly distributed surface contact. This effectively avoids damage to the wire insulation layer caused by local stress concentration, while increasing the friction contact area and preventing the wire from slipping under wind vibration conditions.

[0041] The top and bottom of the limiting groove 11 are provided with slot 111. The pressure cover 12 is engaged with the slot 111 by the locking block 121 fixedly installed on its top and bottom. The top of the fixing block 1 is fixedly installed with a locking bolt 16. The locking block 121 is threadedly connected to the locking bolt 16 by the locking groove 122 opened on its top.

[0042] Align the locking block 121 of the pressure cover 12 with the locking groove 111 on the fixing block 1 and insert it vertically. After pushing the pressure cover 12 into place, tighten the locking bolt 16 so that it is embedded in the locking groove 122 of the locking block 121, thereby locking the pressure cover 12 and the fixing block 1, ensuring both ease of installation and connection strength.

[0043] The top and bottom of the limiting groove 11 are provided with a second slot 112 and a rectangular groove 113. The second slot 112 is used to guide the movement of the protrusion 141. The connecting block 15 is movably installed in the rectangular groove 113. The connecting block 15 is provided with a locking groove 151 that matches the protrusion 141.

[0044] The damping indicator assembly 2 includes a fixed tube 21, a piston 22, and a connecting rod 23. The fixed tube 21 is fixedly installed inside the fixed block 1. The piston 22 is movably installed inside the fixed tube 21. The piston 22 is fixedly connected to the connecting block 15 through the connecting rod 23. A reset plate 24 is fixedly installed on the connecting rod 23. The reset plate 24 is connected to the inner wall of the fixed block 1 through a reset spring 25. A threaded exhaust pipe 26 is provided at the end of the fixed tube 21 away from the connecting rod 23. A cap 27 is threadedly installed on the exhaust pipe 26.

[0045] When the rotating adjusting screw 13 drives the clamping block 14 to move toward the wire, the clamping block 14 drives the connecting rod 23 and piston 22 to move in the fixed tube 21 through the protrusion 141 and the connecting block 15. By selectively installing or removing the cap 27 on the exhaust pipe 26, the air cushion damping that hinders the movement of the clamping block 14 can be established or removed accordingly.

[0046] During initial installation, removing the cap 27 allows the piston 22 to move and smoothly expel air from the fixed tube 21, reducing operating resistance. After installation, the cap 27 is replaced, at which point the fixed tube 21 forms a sealed air chamber. The movement of the piston 22 compresses the internal air, generating a reverse damping force. This air cushion damping effect effectively absorbs and buffers the vibration energy of the conductor, suppresses the loosening tendency of the adjusting screw 13, provides continuous dynamic stability for the clamping system, and significantly improves vibration resistance and long-term reliability.

[0047] It should be noted that the return spring 25 has a preset pre-compression amount in its natural state. This pre-compression force is set to be greater than the normal loosening force of the wire caused by wind vibration but less than the installation fastening force. When the clamping force is relaxed to this pre-tightening force threshold due to wire creep or vibration, the return spring 25 will push the entire linkage system to reset. This characteristic enables the device to automatically identify the normal decay and abnormal relaxation of the clamping force, providing a mechanical basis for the subsequent early warning mechanism.

[0048] A sealing ring is fitted around the piston 22 to form a reliable airtight sliding fit with the inner wall of the fixed tube 21. When the cap 27 is installed, the fixed tube 21, piston 22 and sealing ring together form an airtight cavity. The internal volume of this cavity can only be changed by the slow movement of the piston 22, thereby ensuring a stable and reliable damping effect.

[0049] Example 2

[0050] Reference Figures 7-9In the second embodiment of the present invention, an adaptive equalizing displacement street code is provided. The damping indicator component 2 further includes an indicator block 31. The indicator block 31 is fixedly connected to the connecting block 15 located at the top of the limiting groove 11. The top of the fixing block 1 is provided with a through groove 32 that communicates with the rectangular groove 113. The indicator block 31 is movably disposed in the through groove 32. A scale 33 for marking the clamping state is provided on one side of the through groove 32.

[0051] When the clamping block 14 moves toward the wire, the connecting block 15 drives the indicator block 31 to move within the through groove 32. When the clamping force is relaxed, the reset spring 25 pushes the reset plate 24 and the connecting rod 23 to reset, thereby causing the indicator block 31 to move back within the through groove 32.

[0052] During the clamping process, as the clamping block 14 moves forward, the connecting block 15 drives the indicator block 31 to move towards the closed end of the through slot 32. When the clamping force decreases due to vibration, creep, or other reasons, the return spring 25 releases the stored elastic potential energy, pushing the entire linkage mechanism to reset, causing the indicator block 31 to move back towards the open end of the through slot 32. This movement process realizes the precise conversion of mechanical displacement into visual signal.

[0053] The scale 33 is provided with green, yellow and red areas along the length of the through groove 32. The length range of the green area corresponds to the rated working range of the clamping force, the length range of the yellow area corresponds to the warning range of the clamping force, and the length range of the red area corresponds to the range below the safe threshold of the clamping force.

[0054] A tiered early warning mechanism has been established. The green zone indicates that the clamping force is within a safe range, the yellow zone indicates that it needs to be tightened during the next inspection, and the red zone indicates that the clamping force has fallen below the minimum safe value and needs to be dealt with immediately. This achieves quantitative management of the clamping force status and provides a clear basis for operation and maintenance decisions.

[0055] It should be noted that the indicator block 31 uses a high-contrast color coating to ensure clear visibility even under outdoor lighting conditions. A transparent protective cover can be installed above the through slot 32 to prevent rainwater and dust from affecting the indicating accuracy without obstructing the observation line of sight. In practical applications, maintenance personnel can remotely read the position of the indicator block 31 on the scale 33 from below the pole and quickly determine the clamping status based on the division of the green, yellow, and red areas. Figure 9 As shown, it should be noted that different fill styles in the figure represent different color areas.

[0056] The movement of the indicator block 31 within the through slot 32 corresponds synchronously with the clamping stroke of the clamping block 14. When the indicator block 31 moves to the green area of ​​the scale 33, it indicates that the clamping force has reached the rated working range. When the indicator block 31 moves back to the yellow area of ​​the scale 33 due to the loosening of the clamping force, it indicates that preventive maintenance is required. When the indicator block 31 moves back to the red area, it indicates that the clamping force has fallen below the safety threshold and needs to be adjusted immediately.

[0057] The aforementioned structure transforms invisible clamping force changes into intuitive visual signals, allowing maintenance personnel to determine the clamping status without manual inspection. This enables a shift from periodic maintenance to condition-based maintenance, significantly improving inspection efficiency and safety, while also providing fundamental technical support for line status monitoring in smart grids.

[0058] It should be noted that in the installation process of traditional street clamps, the control of clamping force relies entirely on the operator's experience and feel, lacking objective judgment standards. This subjective judgment method is very likely to lead to improper control of clamping force. If the clamping force is too large, it will damage the insulation layer of the wire due to excessive squeezing, forming initial defect points. In long-term operation, it may also cause stress fatigue of the metal conductor core. If the clamping force is too small, it cannot provide sufficient gripping force. Under the action of dynamic loads such as wind vibration, the wire will have relative displacement with the clamping surface, resulting in continuous fretting wear, which will also damage the insulation layer and may cause the wire strands to break.

[0059] The damping indicator component 2 of the present invention effectively solves this problem through mechanical structure. During the clamping process, the operator only needs to observe the position change of the indicator block 31 on the scale 33. When the indicator block 31 moves to the green area, the operator can stop turning the adjusting screw 13. This design transforms the traditional reliance on experience into intuitive visual judgment, which not only ensures that the clamping force reaches the rated working range, but also effectively avoids wire damage caused by over-tightening.

[0060] This visualized clamping force management method not only improves the reliability of installation quality, but also provides a strong guarantee for the safe operation of the line through real-time status monitoring, realizing the transformation from experience-based operation to precise control. In practical applications, the damping indicator component 2 of this invention can be combined with the UAV inspection system to realize automated status monitoring.

[0061] Specifically, the drone is equipped with a camera and flies to the vicinity of the street code to collect time-series video data of the scale 33, such as a 10-second video. At the same time, it records the wind force, wind direction data and the installation orientation of the street code during this time period, and judges whether the swing of the scale pointer in the time-series data is normal. Based on the judgment result, it is determined whether the street code needs to be maintained.

[0062] It should be noted that wind load is the main external excitation that causes dynamic vibration of the conductor and fluctuation of clamping force. The installation orientation of the street code determines the relative spatial relationship between its clamping system and the wind direction. The two together determine the direction and magnitude of the dynamic load acting on the clamping block 14, which in turn directly affects the vibration amplitude and mode of the indicator block 31 in the through slot 32. When the damping indicator component 2 is functioning normally, the indicator block 31 will exhibit a normal dynamic response that matches the current wind conditions and installation orientation. Once the damping function decays, the dynamic response of the indicator block 31 will be abnormal, such as the swing amplitude exceeding the expected range or irregular drifting under the same wind conditions.

[0063] Therefore, when analyzing time-series video data, the inspection backend uses wind force, wind direction, and installation orientation as key input parameters to establish a benchmark for the dynamic behavior of indicator block 31. By comparing the actual observed swing pattern of indicator block 31 with the benchmark, it can accurately determine whether the working status of damping indicator component 2 is normal, thereby realizing intelligent diagnosis and early warning of the health status of street code and avoiding misjudgment caused by traditional methods.

[0064] After these data are sent to the inspection backend system, staff will comprehensively analyze whether the swing of indicator block 31 is normal based on wind force, wind direction and installation orientation. Since wind force and wind direction and street code installation orientation will affect the dynamic changes of the scale, by comparing the expected behavior, it can be determined whether the clamping force is abnormal. If the swing of indicator block 31 does not conform to the normal mode, personnel will be arranged to carry out targeted maintenance on damping indicator component 2, thereby improving inspection efficiency and safety.

[0065] To further improve the accuracy and efficiency of judgment, the inspection backend system can integrate a fault identification model. This model is trained using multiple sets of time-series video data, wind force, wind direction, street code installation orientation, and their corresponding labels, i.e., whether the clamping force is normal or abnormal. During training, the data is converted into feature vectors and input into a 3D convolutional neural network or other machine learning model (no specific limitation is made here). The model is trained with labels as output and the goal of minimizing the loss function. Training stops when the loss function value is lower than a preset threshold. After training, the model can automatically analyze the real-time collected data and output the clamping status judgment result, realizing intelligent early warning and maintenance decision-making.

[0066] With the cap 27 installed, the damping indicator assembly 2 not only provides stable anti-vibration damping, but also ensures that the indicator block 31 moves smoothly and without shaking in the through slot 32, avoiding misjudgment of the indication due to vibration. At the same time, the preload setting of the return spring 25 provides an accurate action threshold for the entire system, so that the mechanical transmission, damping buffer and visual indication form an organically unified intelligent system.

[0067] The innovation of this invention lies in upgrading the traditional passive fixing structure into an intelligent system with self-monitoring, dynamic adjustment and status feedback functions. Through mechanical structural innovation, it realizes the dynamic maintenance and anti-loosening of clamping force, real-time visual monitoring of clamping status and intelligent management of hierarchical early warning. This design not only solves the technical problems of uncontrollable and invisible clamping force of traditional street code, but also provides a new technical solution for the intelligent operation and maintenance of transmission lines, realizing the transformation of operation and maintenance mode from periodic maintenance to condition-based maintenance.

[0068] In practice, the system parameters can be optimized by adjusting the pre-compression of the reset spring 25 and the volume of the fixed tube 21 according to different wire specifications and usage environment, so as to meet different engineering needs.

[0069] As can be seen from Embodiments 1 and 2, the damping indicator component 2 not only provides dynamic stabilization for the clamping system and effectively suppresses the attenuation of clamping force caused by dynamic loads such as wind vibration, but also provides a reliable working basis for visual indication through its stable damping characteristics. Furthermore, through the indicator component and scale 33 linked with the clamping block 14, real-time visual feedback of the clamping force status is realized, enabling maintenance personnel to remotely and intuitively judge the clamping force level, fundamentally solving the hidden danger of invisible clamping force.

[0070] It also provides a method for using adaptive equalization voltage shift street codes, including the following steps:

[0071] Step 1: Fix the connecting plate to the crossarm of the utility pole or wall with bolts. After completing the installation of the main body of the street code, put the wire into the limiting groove 11 of the fixing block 1, and then snap the cover 12 into place. At the same time, the protrusion 141 of the clamping block 14 and the locking groove 151 of the connecting block 15 are engaged to achieve the initial positioning of the wire and the assembly of the street code.

[0072] Step 2: Rotate the adjusting screw 13 to drive the clamping block 14 to move toward the wire. The arc-shaped clamping groove 142 forms a covering surface contact clamp with the clamping pad 114 with concave and convex textures, which drives the connecting rod 23 and piston 22 to move in the fixed tube 21. At this time, the exhaust pipe 26 cap 27 is in the removed state to ensure that it will not interfere with the operation.

[0073] Step 3: After clamping, install the exhaust pipe 26 and cap 27 to form a sealed air chamber in the fixed pipe 21. At this time, the movement of the piston 22 will compress the internal air to generate a continuous air cushion damping force, which effectively absorbs and buffers the vibration energy of the wire and suppresses the attenuation of the clamping force.

[0074] Step 4: By observing the position of the indicator block 31, which is linked to the connecting block 15, on the scale 33, the clamping status can be monitored in real time. When the indicator block 31 is in the green area, it indicates that the clamping force is normal. When it moves to the yellow area, it indicates that preventive maintenance needs to be arranged. When it enters the red area, it indicates that tightening and adjustment need to be performed immediately.

[0075] In summary, the entire system achieves dynamic maintenance of clamping force and status visualization through the synergistic effect of mechanical transmission, damping buffer and visual indication, forming a complete workflow from installation and positioning, clamping and fixing, damping and anti-loosening to status monitoring.

[0076] The above embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit it. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.

The inner wall of the limiting groove (11) is fixed with a clamping pad (114) with a concave-convex surface. Through the coordinated cooperation of the arc-shaped clamping groove (142) and the clamping pad (114), a surface contact clamping of the wire is formed.

4. The adaptive voltage equalization shift street code according to claim 3, characterized in that: The damping indicator assembly (2) also includes an indicator block (31), which is fixedly connected to a connecting block (15) located at the top of the limiting groove (11). The top of the fixing block (1) is provided with a through groove (32) that communicates with the rectangular groove (113). The indicator block (31) is movably disposed in the through groove (32). A scale (33) for marking the clamping state is provided on one side of the through groove (32).

5. The adaptive voltage equalization shift street code according to claim 4, characterized in that: When the clamping block (14) moves toward the wire, the connecting block (15) drives the indicator block (31) to move in the through groove (32). When the clamping force is relaxed, the reset spring (25) pushes the reset plate (24) and the connecting rod (23) to reset, thereby driving the indicator block (31) to move back in the through groove (32).

6. The adaptive voltage equalization shift street code according to claim 5, characterized in that: The scale (33) is provided with green, yellow and red areas in sequence along the length of the through groove (32). The length range of the green area corresponds to the rated working range of the clamping force, the length range of the yellow area corresponds to the warning range of the clamping force, and the length range of the red area corresponds to the range below the safety threshold of the clamping force.

7. The adaptive voltage equalization shift street code according to claim 6, characterized in that: The movement of the indicator block (31) in the through slot (32) corresponds synchronously with the clamping stroke of the clamping block (14). When the indicator block (31) moves to the green area of ​​the scale (33), it indicates that the clamping force has reached the rated working range. When the indicator block (31) moves back to the yellow area of ​​the scale (33) due to the relaxation of the clamping force, it indicates that preventive maintenance is required. When the indicator block (31) moves back to the red area, it indicates that the clamping force has fallen below the safety threshold and needs to be adjusted immediately.
