Description

Technical Field

[0001] This application relates to the field of power equipment technology, specifically to a multifunctional fixing device for power conductors. Background Technology

[0002] In the power transmission network, the reliable connection between transmission lines and insulators is a crucial element in ensuring power supply stability. As the insulating support component of the transmission line, the insulator's fixing device must not only bear the mechanical load of the transmission line but also adapt to various stress changes in complex environments. This requires the fixing device to have higher stability and reliability.

[0003] Traditional insulator fixing devices mostly use a single bolt fastening method, which has a narrow adjustment range and can only match specific models of insulators. Different fixing devices need to be adapted for different models of insulators, which is costly. In addition, the locking mechanism is prone to loosening in the variable outdoor environment. Furthermore, existing fixing devices generally use rigid connection to the insulator. Outdoors, especially in windy weather, the vibration of the transmission line will impact the fixing device, making both of them extremely prone to wear and aging.

[0004] In addition, existing insulators and wire fixing devices rely on manual inspection for maintenance, which is inefficient and delayed. Maintenance is often carried out only after a fault occurs, making it difficult to detect potential faults in advance.

[0005] To address the aforementioned issues, there is an urgent need to design a fixed device that is highly compatible, stable in performance, and possesses multi-dimensional monitoring capabilities, providing technical support for the precise operation and maintenance and fault early warning of transmission lines. Summary of the Invention

[0006] To overcome the shortcomings of the prior art, this application provides a multifunctional fixing device for power conductors, specifically adopting the following technical solution:

[0007] A multifunctional fixing device for power conductors is used to fix and monitor transmission lines on insulators. The device includes a ring clamping mechanism, a clamping adjustment mechanism, a cable fixing mechanism, and a signal monitoring mechanism.

[0008] The ring clamping mechanism includes a first clamping body and a second clamping body with a semi-ring opening structure. One end of the first clamping body and one end of the second clamping body are hinged together. The other end of the first clamping body is provided with a locking part, and the other end of the second clamping body is provided with a fixing sleeve that cooperates with the locking part. By cooperating with the locking part and the fixing sleeve, the first clamping body and the second clamping body are closed relative to each other to form an installation space located in the middle.

[0009] The clamping adjustment mechanism includes two first connecting screws and two first clamping sleeves. The two first connecting screws are arranged opposite to each other at the connection position between the first clamping body and the second clamping body, and each first connecting screw is threadedly connected to one first clamping sleeve.

[0010] The cable fixing mechanism includes a fixing clamp, and each end of the fixing clamp is provided with a first mounting hole. The first mounting hole is connected through a first connecting screw, and the first clamping screw sleeve is located in the first mounting hole. The first clamping screw sleeve applies a clamping force to the fixing clamp.

[0011] The signal monitoring mechanism is located on the fixed clamp and monitors the status of the fixed clamp and the power transmission line in real time.

[0012] Optionally: the fixing sleeve is provided with a fitting groove, and the bottom of the fitting groove is provided with a first through hole; the locking part is provided with at least one locking hole, and when the first clamping body and the second clamping body are closed in place, the bottom of the locking hole is directly opposite the first through hole.

[0013] Furthermore, a locking component is provided below the fixed sleeve. One end of the locking component has a second mounting hole that mates with the first connecting screw, and the other end of the locking component has an integrally connected locking pin. When the first connecting screw passes through the second mounting hole and clamps the locking component, the locking pin passes through the first through hole and the locking hole in sequence, and the locking part is fixed by the locking pin.

[0014] Furthermore, the inner sides of the first clamping body and the second clamping body are respectively provided with at least one abutting spring, and the abutting spring is connected to a buffer mechanism located inside the first clamping body or the second clamping body.

[0015] Optionally, the buffer mechanism includes a buffer pin and a buffer spring. One end of the buffer pin is connected to the side surface of the abutment spring, and the other end of the buffer pin is provided with an abutment plate. The abutment plate abuts against the buffer spring, which is in a partially compressed state. When the first clamping body and the second clamping body are closed and installed onto the insulator, the buffer spring applies pressure to the abutment spring through the buffer pin, causing the abutment spring to deform and abut against the surface of the insulator.

[0016] Optionally, the signal monitoring mechanism includes a microprocessor and a communication antenna. The microprocessor receives signal data from sensors arranged on the fixed clamp and the power transmission line, and generates status data of the fixed clamp and the power transmission line, which is then remotely transmitted to a cloud platform via the communication antenna.

[0017] Optionally: A sensor side plate is provided on the side of the fixed clamp, and a first vibration sensor is provided on the sensor side plate. The first vibration sensor is connected to the signal monitoring mechanism through a signal line and is used to detect the vibration state of the power transmission line.

[0018] Optionally: The top of the fixing clamp is provided with a clamping block, and the surface of the clamping block is provided with a strain sensor and a pressure sensor. The strain sensor and the pressure sensor are respectively connected to the signal monitoring mechanism through signal lines. The strain sensor is used to monitor the tension of the transmission line, and the pressure sensor is used to monitor the contact pressure between the transmission line and the insulator.

[0019] Optionally: A first magnet is provided on the side of the first clamping screw sleeve, and a magnetic sensor is provided on the edge of the first mounting hole in the fixing clamp. The deflection of the first magnet is collected by the magnetic sensor, thereby monitoring the offset of the first clamping screw sleeve.

[0020] Optionally: The upper end of the first clamping screw sleeve is provided with a polygonal screwing part, a knob is provided above the screwing part, a through first thread is provided in the middle of the knob, a warning light is provided at the upper end of the knob, and a groove is provided at the lower end of the knob to fit the screwing part.

[0021] The technical solution of this application achieves the following beneficial effects:

[0022] The multi-functional fixing device for power conductors disclosed in this application, through the opening and closing structure of the first and second clamping bodies and the adjustment function of the first connecting screw, can flexibly match insulators of different specifications. The precise fit between the locking part and the fixing sleeve improves installation reliability and reduces equipment selection and replacement costs. Furthermore, the device utilizes a buffer mechanism composed of abutment springs and buffer springs to effectively absorb the vibration and impact of transmission lines, preventing wear of the transmission line insulation layer and stress aging of the insulators, thus extending the device's service life. Simultaneously, a signal monitoring mechanism collects data in real time through various sensors such as vibration and strain sensors. This data is processed by a microprocessor and transmitted remotely to the cloud via a communication antenna, replacing traditional manual inspection methods. This enables early fault detection and provides precise data for equipment maintenance by monitoring factors such as clamping sleeve misalignment and transmission line tension, significantly reducing operation and maintenance costs and downtime, and improving the safe operation level of the power transmission network.

Detailed Implementation

[0033] The present application will now be further described with reference to the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solutions of the present application and should not be construed as limiting the scope of protection of the present application. It should be noted that the following detailed descriptions are exemplary and intended to provide further explanation of the present application.

[0034] Example 1:

[0035] like Figure 1 As shown in Embodiment 1, a multifunctional fixing device for power conductors is disclosed for fixing and monitoring transmission lines on insulators. The device includes a ring clamping mechanism 1, a clamping adjustment mechanism 2, a cable fixing mechanism 3, and a signal monitoring mechanism 4.

[0036] Specifically, in this embodiment 1, the annular clamping mechanism 1 is the main support body of the device, primarily used to reliably fix the device to the insulator. Combined with... Figure 2 As shown, the annular clamping mechanism 1 includes a first clamping body 101 and a second clamping body 102 with a semi-annular opening structure. In this embodiment 1, the first clamping body 101 and the second clamping body 102 are preferably made of high-strength aluminum alloy or high-strength plastic, and can be coated with an anti-corrosion coating to avoid surface corrosion and affect the structural strength.

[0037] More specifically, such as Figure 2 As shown, in this embodiment 1, one end of the first clamping body 101 and one end of the second clamping body 102 are hinged together by a pin, which ensures the flexibility of the opening and closing action of the clamping bodies. The other end of the first clamping body 101 has an integrally formed locking part 1011, which preferably has a cuboid structure with multiple locking holes 1012 spaced apart along its length. The other end of the second clamping body 102 has a fixing sleeve 1021 that mates with the locking part 1011. For metal materials, the fixing sleeve 1021 can be welded to the end of the second clamping body 102, while for plastic materials, it is manufactured using an integral injection molding process. The fixing sleeve 1021 has an internal fitting groove 1022 that matches the contour of the locking part 1011, and the bottom of the fitting groove 1022 has a first through hole 1023 corresponding to the position of the locking hole 1012. When the first clamping body 101 and the second clamping body 102 are closed in place, the lower part of the locking hole 1012 will be directly aligned with the first through hole 1023. Furthermore, the first clamping body 101 and the second clamping body 102 close together to form a central mounting space for fixing the insulator. At this time, the locking part 1011 will be embedded inside the fitting groove 1022, and the locking hole 1012 and the first through hole 1023 will be precisely aligned, providing a positioning basis for subsequent mechanical locking.

[0038] Furthermore, in this embodiment 1, the clamping adjustment mechanism 2 is used on the one hand to connect the ring clamping mechanism 1 and the cable fixing mechanism 3 and provide clamping force to the cable fixing mechanism 3, and on the other hand to adjust the distance between the cable fixing mechanism 3 and the ring clamping mechanism 1 so as to adapt to different specifications of transmission lines to fit tightly to the top of the insulator.

[0039] Specifically, in combination Figure 1As shown, the clamping adjustment mechanism 2 includes two first connecting screws 201 and two first clamping sleeves 202. Both the first connecting screws 201 and the first clamping sleeves 202 can be coated with a corrosion-resistant and fire-resistant coating. The two first connecting screws 201 are arranged opposite to each other at the connection position of the first clamping body 101 and the second clamping body 102. That is, in this embodiment 1, one of the first connecting screws 201 is located at the hinge position of the first clamping body 101 and the second clamping body 102, which can replace the original hinge pin. The other first connecting screw 201 is arranged on the fixing sleeve 1021 of the second clamping body 102. The fixing sleeve 1021 is provided with a through hole adapted to the first connecting screw 201. The lower end of the first connecting screw 201 passes through the through hole of the fixing sleeve 1021, and the lower end of the first connecting screw 201 is limited and fixed by a protrusion.

[0040] Furthermore, in this embodiment 1, each first connecting screw 201 is equipped with one of the aforementioned first clamping screw sleeves 202; as a preferred structure, such as Figure 8 As shown, in this embodiment 1, the first clamping sleeve 202 includes an integrally connected main body 2022 and a screwing part 2021 located at the upper end. The screwing part 2021 is polygonal in shape, and a threaded hole is provided in the middle of the first clamping sleeve 202, which passes through the main body 2022 and the screwing part 2021. The threaded hole matches the first connecting screw 201. In this embodiment 1, a limiting boss extends radially from the side of the screwing part 2021. The limiting boss can abut against the cable fixing mechanism 3, thereby applying a clamping force to the cable fixing mechanism 3.

[0041] Furthermore, the cable fixing mechanism 3 in this embodiment 1 is used to directly fix the transmission line. This cable fixing mechanism 3 includes a fixing clamp 301, which is preferably formed using a zinc-aluminum alloy die-casting process, and has a coating with anti-corrosion and high-temperature resistance on its surface to extend its service life. Figure 6 As shown, the fixed clamp 301 has first mounting holes 3011 at both ends, and the positions of the first mounting holes 3011 and the first connecting screws 201 correspond one-to-one. During installation, each first mounting hole 3011 will be connected to a first connecting screw 201, and the first clamping sleeve 202 will be screwed into the first connecting screw 201 and located inside the first mounting hole 3011. By tightening the first clamping sleeve 202, an axial clamping force can be applied to the fixed clamp 301, so that the fixed clamp 301 and the power transmission line are tightly fitted.

[0042] Furthermore, such as Figure 7As shown, in this embodiment 1, the fixing clamp 301 has a clamping block 302 located in the middle near its bottom. The clamping block 302 is detachably connected to the fixing clamp 301, such as by a sliding groove connection or a snap-fit ​​connection, to facilitate the replacement of clamping blocks 302 of different specifications to accommodate the fixing of transmission lines of different diameters. As a preferred embodiment, the lower surface of the clamping block 302 is arc-shaped, and this arc-shaped surface can be covered with a 3mm thick silicone rubber insulation layer to effectively prevent wear on the transmission line surface and improve the anti-slip performance of the clamping. When the fixing clamp 301 is used to fix the transmission line, the arc-shaped surface of the clamping block 302 directly abuts against the surface of the transmission line. The clamping block 302 and the top of the insulator work together to clamp the transmission line, achieving stable fixing.

[0043] Furthermore, in this embodiment 1, the signal monitoring mechanism 4 is integrated inside a sealed mounting box on top of the fixed clamp 301. This signal monitoring mechanism 4 allows for real-time monitoring of the status of the fixed clamp 301 and the transmission line. The signal monitoring mechanism 4 includes a microprocessor and a communication antenna. The microprocessor receives signal data from sensors arranged on the fixed clamp 301 and the transmission line, performs filtering and noise reduction preprocessing to generate standardized status data for the fixed clamp 301 and the transmission line, and then remotely transmits this data to a cloud monitoring platform via the communication antenna to achieve basic fault early warning functionality.

[0044] In addition, in this embodiment 1, the signal monitoring mechanism 4 is equipped with a variety of basic sensors distributed on the fixed clamp 301 and the power transmission line.

[0045] like Figure 6 As shown, in this embodiment 1, a sensor side plate 303 is provided on the side of the fixed clamp 301. A first vibration sensor is provided on the sensor side plate 303, which is connected to the signal monitoring mechanism 4 through a signal line. The first vibration sensor is used to collect the vibration frequency and amplitude parameters of the transmission line in order to detect the vibration state of the transmission line.

[0046] Furthermore, such as Figure 7 As shown in Embodiment 1, the clamping block 302 located at the bottom of the fixed clamp 301 has a strain gauge sensor 3021 and a pressure sensor 3022 on its lower surface. The strain gauge sensor 3021 and the pressure sensor 3022 are respectively connected to the signal monitoring mechanism 4 via signal lines. The strain gauge sensor 3021 can monitor the tension of the transmission line. Once the stress on the transmission line exceeds the threshold, a local audible and visual alarm will be triggered to assist maintenance personnel in quickly locating the fault. The pressure sensor 3022 monitors the contact pressure between the transmission line and the insulator, and triggers an alarm when the pressure is abnormal.

[0047] Furthermore, such as Figure 3As shown, in this embodiment 1, to improve the locking reliability of the annular clamping mechanism 1, a locking member 106 is provided below the fixed sleeve 1021. The locking member 106 is generally L-shaped and is preferably made of Q235 steel. One end of the locking member 106 has a second mounting hole adapted to the first connecting screw 201, while the other end has an integrally connected locking pin 1061. When the locking part 1011 is inserted into the fitting groove 1022, the first connecting screw 201 passes through the second mounting hole to fix the locking member 106 to the bottom of the fixed sleeve 1021. At this time, the locking pin 1061 at the other end will pass through the first through hole 1023 and the locking hole 1012 in sequence and fix the locking part 1011, thereby forming a mechanical locking structure, which can effectively prevent the first clamping body 101 and the second clamping body 102 from accidentally loosening.

[0048] More specifically, the installation process of the multi-functional fixing device for power conductors described in Embodiment 1 is as follows:

[0049] First, the first clamping body 101 and the second clamping body 102 are opened by the hinge structure and placed on the insulator near the top. Then, the first clamping body 101 and the second clamping body 102 are closed towards the center so that the locking part 1011 is fully embedded in the fitting groove 1022 of the fixing sleeve 1021, ensuring that the locking hole 1012 and the first through hole 1023 are precisely aligned.

[0050] Then, the locking pin 1061 of the locking member 106 is passed through the first through hole 1023 and the locking hole 1012 in sequence, and the first connecting screw 201 is passed through the second mounting hole to fix the locking member 106 to the bottom of the fixing sleeve 1021. At this time, the installation and fixing of the ring clamping mechanism 1 is completed.

[0051] Next, place the transmission line on top of the insulator and place the fixing clamp 301 above the transmission line. Adjust the position of the fixing clamp 301 so that the first mounting holes 3011 at both ends are aligned with the first connecting screw 201. Insert the first connecting screw 201 through the first mounting hole 3011, screw in the first clamping screw sleeve 202 and tighten it according to the preset torque so that the clamping block 302 is tightly attached to the transmission line.

[0052] Finally, the mounting box of the signal monitoring mechanism 4 is fixed to the top of the fixing clamp 301 to complete the connection and debugging of the sensor signal line and realize the installation of the whole device.

[0053] In this embodiment 1, the combination of mechanical locking and screw adjustment achieves reliable fixation of both the insulator and the transmission line. The device has a simple structure and is quick and easy to install. Simultaneously, the signal monitoring mechanism 4 effectively identifies faults such as loose transmission lines and vibrations in light winds, significantly improving maintenance response efficiency.

[0054] Example 2:

[0055] The multifunctional fixing device for power conductors in this embodiment 2 is based on the device in embodiment 1. The device's structural adaptability and monitoring dimensions are further optimized to expand its applicability and improve its fault identification capability.

[0056] Specifically, in order to adapt to insulators of different diameters, in this embodiment 2, three abutting springs 103 are evenly arranged circumferentially on the inner side surfaces of the first clamping body 101 and the second clamping body 102. The abutting springs 103 are preferably made of 65Mn spring steel and their surfaces are galvanized to improve corrosion resistance.

[0057] The aforementioned abutment spring 103 is connected to a buffer mechanism disposed inside the clamping body. Figure 4 and Figure 5 As shown, the buffer mechanism includes a buffer pin 104 and a buffer spring 105. One end of the buffer pin 104 is connected to the side surface of the abutment piece 103, while the other end is connected to an abutment plate. The abutment plate engages with the buffer spring 105, which is in a pre-compressed state. When the device is installed on the surface of the insulator, the buffer spring 105 applies continuous pressure to the abutment piece 103 through the buffer pin 104, causing the piece to undergo adaptive deformation and fit tightly against the surface of the insulator. This effectively avoids damage to the insulator caused by hard contact and also ensures stable contact with the insulator, improving clamping stability.

[0058] In addition, combined Figure 8 As shown in this embodiment 2, a knob 203 is added above the screwing portion 2021 of the first clamping screw sleeve 202. The knob 203 has a through first thread in the middle, and a groove at the lower end of the knob 203 that fits the screwing portion 2021 of the first clamping screw sleeve 202. On the one hand, the first clamping screw sleeve 202 can be screwed on by directly and manually turning the knob 203, which is convenient for disassembly and maintenance. On the other hand, since the first thread of the knob 203 cooperates with the first connecting screw 201, the first clamping screw sleeve 202 can be tightened, preventing the first clamping screw sleeve 202 from loosening, thereby improving the connection stability. In addition, a warning light 2031 is provided at the upper end of the knob 203. The warning light 2031 can be connected to the mounting box of the signal monitoring mechanism 4 through a connecting wire, and a photovoltaic panel can be installed on the top surface of the mounting box to power the warning light 2031, causing the warning light 2031 to flash, which can intuitively remind maintenance personnel.

[0059] Furthermore, in this embodiment 2, the types of sensors configured in the signal monitoring mechanism 4 are expanded. A temperature sensor is added to the contact area between the fixed clamp 301 and the transmission line to monitor the operating temperature of the transmission line in real time, which can effectively prevent overheating failures caused by overload; combined with Figure 8As shown, a first magnet 2023 is embedded on the side of the first clamping sleeve 202, and a magnetic sensor 3012, such as a Hall effect magnetic sensor 3012, is installed around the edge of the first mounting hole 3011 of the fixing clamp 301. The sensor can monitor the offset angle of the first clamping sleeve 202 by collecting the deflection data of the first magnet 2023. Once the offset angle of the first clamping sleeve 202 exceeds the threshold, a loosening warning will be triggered.

[0060] The device in this embodiment 2 expands the range of compatible insulator specifications, making it compatible with various types of transmission equipment and significantly reducing the cost of line modification and equipment replacement. Simultaneously, the buffer mechanism and abutment spring 103 ensure that the clamping mechanism evenly presses the insulator, effectively protecting the insulator's enamel surface from damage and ensuring a stable connection between the device and the insulator. Furthermore, by adding temperature and sleeve offset monitoring, multi-dimensional monitoring of tension, vibration, temperature, and connection status can be achieved, improving the accuracy of fault identification.

[0061] The above description is only a preferred embodiment of this application. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of this application, and these improvements and modifications should also be considered within the scope of protection of this application.
