Description

Technical Field

[0001] The present invention relates to the technical field of multi - split spacer dampers, and particularly to a multi - split spacer damper convenient for high - altitude installation. Background Art

[0002] Multi - split spacer dampers play a crucial role in transmission lines. Their main function is to fix multi - split conductors, prevent the conductors from whipping and dancing with each other, maintain the spacing between each split conductor, and ensure the safe and stable operation of the transmission line. With the continuous development of transmission technology, higher requirements are put forward for the performance and installation convenience of multi - split spacer dampers.

[0003] In the prior art, there are already various types of multi - split spacer dampers. For example, the multi - split spacer damper disclosed in the patent document with the patent publication number CN221428549U adopts a traditional structural design, and fixes multiple clamps on the cable through connecting parts such as bolts. Although this structure can fix the cable to a certain extent, there are some obvious deficiencies in practical applications.

[0004] In terms of installation, the installation process of traditional spacer dampers is rather cumbersome. Installers need to tighten multiple bolts one by one, which not only consumes a large amount of time and labor, but also has a high operation difficulty in the high - altitude working environment, resulting in low installation efficiency. In addition, since bolt connection requires precise alignment and tightening torque control, if the installation is improper, it is easy to cause uneven clamping force of the clamp on the cable, affecting the fixing effect of the spacer damper and even potentially causing safety hazards.

[0005] In terms of structural design, the structure of traditional spacer dampers is relatively fixed and it is difficult to adapt to the cable requirements with different split numbers and different spacings. When it is necessary to transform or adjust the transmission line, the entire spacer damper often needs to be replaced, increasing the cost and construction difficulty. Summary of the Invention

[0006] (I) Technical Problems to be Solved

[0007] Aiming at the deficiencies of the prior art, the present invention provides a multi - split spacer damper convenient for high - altitude installation. By setting the spacer damper as an inner - outer ring structure that is sleeved together and can rotate relative to each other, and half of the clamps are respectively arranged on the inner and outer rings. When the inner and outer rings are rotated, the clamps can synchronously clamp the cable. This design effectively simplifies the installation process. Installers only need to rotate the inner and outer rings to complete the simultaneous fixation of multiple cables, without having to tighten bolts one by one like traditional spacer dampers, greatly improving the installation efficiency and reducing the installation difficulty, and solving the problems in the prior art that installers need to tighten multiple bolts one by one, consuming a large amount of time and labor, and having a high operation difficulty and low installation efficiency in the high - altitude working environment.

[0008] (2) Technical solution

[0009] To achieve the above object, the present invention provides the following technical solution:

[0010] A multi-split spacer bar convenient for high-altitude installation, including an outer ring composed of two front and rear annular plates. An inner ring is rotatably connected in the middle of the outer ring. A plurality of spacer clips are arranged on the outer ring. The front and rear sides of any one spacer clip are respectively fixed on two connecting plates, and the two connecting plates are respectively fixed on two plates inside the inner ring. Any one spacer clip includes a fixed part and a movable part. The fixed part is fixed on the connecting plate, and the movable part is movably connected to the fixed part;

[0011] A plurality of trigger devices corresponding to the spacer clips one by one are fixedly arranged on the inner ring. A driving device is also arranged on the inner side of the outer ring. Circular teeth are arranged on the inner side of the inner ring. The driving device drives the inner ring to rotate relative to the outer ring. When the inner ring rotates, it drives the trigger device to move relative to the spacer clip, so that the movable part moves to clamp the cable.

[0012] Preferably, in any one spacer clip, the fixed part is a semi-circular hook, and the opening of the fixed part faces the center of the outer ring;

[0013] The movable part is rotatably connected to the fixed part. A central groove is arranged at the center of the fixed part, and the movable part is rotatably connected in the central groove;

[0014] The trigger device is a triangular plate. The three sides of the trigger device are an elastic plate, a fixed plate and a support plate respectively. The fixed plate is fixed on the inner ring, and the fixed plate abuts against the lower side of the movable part. One end of the support plate is fixed on the elastic plate, the other end is fixed on the fixed plate or connected inside the inner ring.

[0015] Preferably, a chute opening is arranged on the inner ring. One end of the support plate is fixed on a slider in the chute opening. The inner ring is a hollow structure. A plurality of pushing devices corresponding to the trigger devices one by one are arranged in the cavity inside the inner ring. A push rod is connected to the pushing device. The other end of the push rod is rotatably connected to a movable block on one side of the slider. The movable block is slidably connected to the slider. A pressure sensor is arranged in the pushing device. The pushing device provides variable elastic force for the elastic plate and detects the jitter of the cable according to the pressure of the elastic plate.

[0016] Preferably, the pushing device is a hydraulic cylinder. When the pressure sensor in the pushing device detects that the pressure received by the elastic plate exceeds a preset value, it controls the pushing device to push the slider to slide, improving the elasticity of the elastic plate, so as to increase the clamping force on the cable when the jitter is severe.

[0017] Preferably, in any connecting plate, one end is fixedly connected to both sides of the fixing part, a fixing shaft is arranged in the middle, and a movable shaft is arranged at the other end. The fixing shaft passes through the outer ring and is rotatably connected to the outer ring. A side groove is arranged at the position corresponding to the fixing shaft on the inner ring side surface. The inner end of the fixing shaft abuts against the side groove. An activity groove is arranged at the position corresponding to the movable shaft on the outer ring, and the movable shaft is movably connected in the activity groove.

[0018] Preferably, the driving device includes:

[0019] A driving column, the front and rear ends of which are rotatably connected to the front and rear plates of the outer ring. The length of the driving column is greater than the width of the outer ring, that is, at least one end of the driving column protrudes from one side of the outer ring;

[0020] A cover plate, which is detachably fixed on the outer ring and used to wrap the driving column. A locking block is fixed at the middle position inside the cover plate;

[0021] Circular teeth meshing with the inner side of the inner ring are arranged on the outer side of the driving column. The circular teeth are distributed on the front and rear sections of the driving column, and no circular teeth are arranged at the middle position of the driving column. In the non-locked state, the locking block is located at the middle position of the driving column. When the driving column rotates, it drives the inner ring to rotate. In the locked state, by knocking one end of the driving column, the driving column slides, so that the locking block is stuck on the circular teeth of the driving column, playing a role in locking the driving column and the inner ring.

[0022] Preferably, one end of the movable part is rotatably connected inside the fixed part. The movable part is of a C-shaped structure. An inner concave surface is arranged on the inner side and an outer convex surface is arranged on the outer side of the movable part. The inner concave surface is used to squeeze the cable, and the outer convex surface is used to abut against the elastic plate. An insulating rubber pad is arranged on the surface of the inner concave surface.

[0023] Preferably, scale marks are arranged on the outer side of the inner ring, and an indicating arrow is arranged at the position corresponding to the scale marks on the outer ring. By observing the relative position of the scale marks and the indicating arrow, the rotation angle of the inner ring relative to the outer ring can be visually judged, so as to accurately control the clamping degree of the spacer clamp on the cable.

[0024] Preferably, the pushing device is connected to a power source, and the power source is also connected to a photovoltaic power generation module. The photovoltaic power generation module includes a micro photovoltaic panel arranged on the outer side of the outer ring.

[0025] Preferably, an in-built level is arranged inside the inner ring and can be directly viewed from the outside through a transparent observation window, which helps the operator quickly judge whether the inner ring and the spacer clamp are in a horizontal state during high-altitude installation, ensuring uniform clamping of the cable and avoiding uneven local stress on the cable caused by inclination.

[0026] (III) Beneficial effects

[0027] Compared with the prior art, the present invention provides a multi-split spacer bar that is convenient for high-altitude installation, having the following beneficial effects:

[0028] 1. For this multi-split spacer bar that is convenient for high-altitude installation, by designing the multi-split spacer bar as a structure composed of a relatively rotatable outer ring and an inner ring, multiple spacer clips are arranged on the outer ring. The spacer clip is composed of a fixed part and a movable part. The fixed part is fixed on the outer ring, and the movable part is movably connected to the fixed part. A triggering device is fixed on the inner ring. When installing at high altitude, rotating the inner ring drives the triggering device to move, and the triggering device pushes the movable part to move, so that the movable part and the fixed part simultaneously clamp multiple cables, improving the installation efficiency, and realizing a modular structural design, achieving the effect of widely adapting to various types of cables, and effectively reducing the construction cost and time cost.

[0029] 2. For this multi-split spacer bar that is convenient for high-altitude installation, by designing the fixed part as a semi-circular hook with an opening facing the center of the outer ring, the movable part is rotatably connected inside the fixed part. At the same time, the triggering device is designed as a triangular plate, and its fixing plate abuts against the lower side of the movable part, realizing a unique structural layout. When installing, the semi-circular hook-shaped fixed part can quickly position the spacer bar at a suitable position on the cable. The triggering device is composed of an elastic plate, a fixing plate and a supporting plate. This structure can provide elastic support for the cable. When the cable is displaced or shaken due to external factors, the elastic plate deforms accordingly, playing a buffering role to avoid damage to the cable due to rigid connection. It achieves the effects of facilitating cable positioning, providing stable and elastic support for the cable, and improving the stability and safety of cable operation.

[0030] 3. For this multi-split spacer bar that is convenient for high-altitude installation, by providing a chute opening on the inner ring, one end of the supporting plate is fixed on the slider in the chute opening, a pushing device is arranged inside the inner ring, and the pushing device is connected to the slider through a push rod, realizing the function of adjustable supporting force. The pressure sensor in the pushing device can push the slider through the push rod according to the cable jitter situation, adjust the position of the triggering device, and change the supporting force on the cable. At the same time, the inner ring adopts a hollow structure, greatly reducing the overall weight of the spacer bar, facilitating high-altitude installation and transportation. The hollow structure can also drain water in rainy days, avoiding damage to the spacer bar caused by water accumulation such as corrosion, achieving the effects of being able to flexibly adjust the supporting force according to actual needs, reducing weight, improving drainage performance, extending the service life of the spacer bar, and ensuring the reliability of power transmission.

[0051] Embodiment 1:

[0052] This embodiment provides a multi-split spacer bar that is convenient for high-altitude installation and has the following technical features.

[0053] Please refer to Figures 1 - 10 , a multi-split spacer bar that is convenient for high-altitude installation, including an outer ring 1 composed of two front and rear annular plates. An inner ring 2 is rotatably connected in the middle of the outer ring 1. A plurality of spacer clips 3 are arranged on the outer ring 1. The front and rear sides of any one spacer clip 3 are respectively fixed on two connecting plates 33. The two connecting plates 33 are respectively fixed on the front and rear two plates inside the inner ring 2. Any one spacer clip 3 includes a fixed part 31 and a movable part 32. The fixed part 31 is fixed on the connecting plate 33, and the movable part 32 is movably connected to the fixed part 31;

[0054] A plurality of trigger devices 4 corresponding to the spacer clips 3 one by one are fixedly arranged on the inner ring 2. A driving device 5 is further arranged on the inner side of the outer ring 1. Circular teeth are arranged on the inner side of the inner ring 2. The driving device 5 drives the inner ring 2 to rotate relative to the outer ring 1. When the inner ring 2 rotates, the trigger device 4 is driven to move relative to the spacer clip 3, so that the movable part 32 moves to clamp the cable 9.

[0055] Furthermore, in any one of the spacer clips 3, the fixing part 31 is a semi-circular hook, and the opening of the fixing part 31 faces the center of the outer ring 1.

[0056] The movable part 32 is rotatably connected to the fixing part 31. A central groove 311 is arranged at the center of the fixing part 31, and the movable part 32 is rotatably connected in the central groove 311.

[0057] The trigger device 4 is a triangular plate. The three sides of the trigger device 4 are an elastic plate 41, a fixing plate 42, and a supporting plate 43 respectively. The fixing plate 42 is fixed on the inner ring 2, and the fixing plate 42 abuts against the lower side of the movable part 32. One end of the supporting plate 43 is fixed on the elastic plate 41 and the other end is fixed on the fixing plate 42.

[0058] Furthermore, in any one of the connecting plates 33, one end is fixedly connected to both sides of the fixing part 31, a fixing shaft 331 is arranged in the middle, and a movable shaft 332 is arranged at the other end. The fixing shaft 331 passes through the outer ring 1 and is rotatably connected to the outer ring 1. A side groove 21 is arranged on the inner ring 2 corresponding to the position of the fixing shaft 331. The inner end of the fixing shaft 331 abuts against the side groove 21. An activity groove 11 is arranged on the outer ring 1 corresponding to the position of the movable shaft 332, and the movable shaft 332 is movably connected in the activity groove 11.

[0059] Furthermore, the driving device 5 includes:

[0060] A driving column 51, the front and rear ends of which are rotatably connected to the front and rear two plates of the outer ring 1. The length of the driving column 51 is greater than the width of the outer ring 1, that is, at least one end of the driving column 51 protrudes from one side of the outer ring 1.

[0061] A cover plate 52, which is detachably fixed on the outer ring 1 and is used to wrap the driving column 51. A lock block 53 is fixed at the middle position inside the cover plate 52.

[0062] Circular teeth meshing with the inner side of the inner ring 2 are arranged on the outer side of the driving column 51. The circular teeth are distributed on the front and rear two sections of the driving column 51, and no circular teeth are arranged at the middle position of the driving column 51. In the non-locked state, the lock block 53 is located at the middle position of the driving column 51. When the driving column 51 rotates, it drives the inner ring 2 to rotate. In the locked state, by knocking one end of the driving column 51, the driving column 51 slides, so that the lock block 53 is stuck on the circular teeth of the driving column 51, playing a role in locking the driving column 51 and the inner ring 2.

[0063] Further provided, one end of the movable part 32 is rotatably connected inside the fixed part 31. The movable part 32 is in a C-shaped structure. An inner concave 321 is provided on the inner side of the movable part 32, and an outer convex 322 is provided on the outer side. The inner concave 321 is used to squeeze the cable 9, and the outer convex 322 is used to abut against the elastic plate 41. An insulating rubber pad is provided on the surface of the inner concave 321.

[0064] Further provided, scale marks are provided on the outer side of the inner ring 2, and indicating arrows are provided at the positions of the outer ring 1 corresponding to the scale marks. By observing the relative positions of the scale marks and the indicating arrows, the rotation angle of the inner ring 2 relative to the outer ring 1 can be visually judged, so as to accurately control the clamping degree of the spacer clip body 3 on the cable 9.

[0065] Further provided, an in-built level is provided inside the inner ring 2 and can be directly viewed from the outside through a transparent observation window, which helps the operator to quickly judge whether the inner ring and the spacer clip body are in a horizontal state during high-altitude installation, ensuring uniform clamping of the cable and avoiding uneven local stress on the cable caused by inclination.

[0066] Further provided, a flexible rubber buffer layer is provided on the edge of the movable part 32. During the process of clamping the cable, this buffer layer can effectively avoid hard friction damage between the movable part and the cable, and at the same time enhance the adaptability and fitting degree to cables with different diameters.

[0067] Further provided, the locking block 53 of the driving device 5 is provided with an intelligent sensing component. When the locking block is locked with the circular teeth of the driving column 51, if abnormal shaking or force change of the spacer bar is detected, the intelligent sensing component can automatically unlock and allow the inner ring 2 to rotate a certain angle relative to the outer ring 1, playing a buffer protection role. After the abnormal situation is eliminated, it can automatically lock again, effectively avoiding damage to the spacer bar and the cable caused by external force impact. The driving column 51 of the driving device 5 is made of hollow carbon fiber material, which greatly reduces the weight while ensuring the structural strength, and a wire channel is reserved inside for connecting the lines of the in-built sensor and the external monitoring device to realize signal transmission.

[0068] Further provided, a sealing dust cover is provided between the outer ring 1 and the inner ring 2, which can effectively block impurities such as high-altitude dust and sand from entering the rotating connection part, reduce wear, and extend the overall maintenance period and service life of the spacer bar.

[0069] Further provided, an operating handle is provided at one end of the driving column 51 protruding from the outer ring 1. The operating handle is of a foldable structure, which is convenient for high-altitude operators to operate the driving column 51 to rotate, and can be folded and retracted when not in use, avoiding obstacles to high-altitude operations. Or, inner hexagon lock catches are provided at both ends of the driving column 51.

[0070] Further, a plurality of anti-slip protrusions are provided on the outer surface of the outer ring 1 to increase the friction when held by high-altitude operators and prevent the spacer bar from slipping during installation.

[0071] Further, the fixed part 31 and the movable part 32 of the spacer clamp body 3 are made of high-strength aluminum alloy material, which reduces the overall weight while ensuring the structural strength and facilitates high-altitude installation operations.

[0072] Working principle: Based on the relative rotation structure of the outer ring 1 and the inner ring 2. A plurality of spacer clamp bodies 3 are provided on the outer ring 1. Each spacer clamp body 3 is composed of a fixed part 31 and a movable part 32. The fixed part 31 is fixed to the outer ring 1, and the movable part 32 is movably connected to the fixed part 31. A triggering device 4 is fixed on the upper side of the inner ring 2. During high-altitude installation operations, the inner ring 2 is rotated, and the rotation of the inner ring 2 drives the triggering device 4 to move synchronously. Since the fixed plate 42 of the triggering device 4 (triangle plate) abuts against the lower side of the movable part 32, when the triggering device 4 moves, it will push the movable part 32, enabling it to cooperate with the fixed part 31 to clamp a plurality of cables 9. Among them, the fixed part 31 is designed as a semi-circular hook with an opening facing the center of the outer ring 1, which can quickly locate the appropriate position of the spacer bar and the cable 9 at the initial stage of installation. The structure composed of the elastic plate 41, the fixed plate 42, and the support plate 43 of the triggering device 4 not only ensures that the trigger pushes the movable part 32 under normal conditions, but also when the cable 9 is displaced or shaken due to external factors, the elastic plate 41 can deform to play a buffering role and prevent the cable 9 from being damaged due to rigid connection. In this way, the spacer bar realizes efficient installation, modular adaptation to different cables, and at the same time ensures the stability and safety of the cable 9 during operation.

[0073] Embodiment 2:

[0074] This embodiment provides a multi-split spacer bar that is convenient for high-altitude installation and has the following technical features.

[0075] Please refer to Figures 11 - 15 , a multi-split spacer bar that is convenient for high-altitude installation, including an outer ring 1 composed of two front and rear annular plates. The inner ring 2 is rotatably connected in the middle of the outer ring 1. A plurality of spacer clamp bodies 3 are provided on the outer ring 1. The front and rear sides of any one spacer clamp body 3 are respectively fixed on two connecting plates 33, and the two connecting plates 33 are respectively fixed on the front and rear two plates inside the inner ring 2. Any one spacer clamp body 3 includes two parts: a fixed part 31 and a movable part 32. The fixed part 31 is fixed on the connecting plate 33, and the movable part 32 is movably connected to the fixed part 31;

[0076] A plurality of trigger devices 4 corresponding to the spacer clips 3 one by one are fixedly arranged on the inner ring 2. A driving device 5 is further arranged on the inner side of the outer ring 1. Circular teeth are arranged on the inner side of the inner ring 2. The driving device 5 drives the inner ring 2 to rotate relative to the outer ring 1. When the inner ring 2 rotates, the trigger device 4 is driven to move relative to the spacer clip 3, so that the movable part 32 moves to clamp the cable 9.

[0077] Furthermore, in any one of the spacer clips 3, the fixing part 31 is a semi-circular hook, and the opening of the fixing part 31 faces the center of the outer ring 1;

[0078] The movable part 32 is rotatably connected to the fixing part 31. A central groove 311 is arranged at the center of the fixing part 31, and the movable part 32 is rotatably connected in the central groove 311;

[0079] The trigger device 4 is a triangular plate. The three sides of the trigger device 4 are an elastic plate 41, a fixing plate 42, and a support plate 43 respectively. The fixing plate 42 is fixed on the inner ring 2, the fixing plate 42 abuts against the lower side of the movable part 32, and one end of the support plate 43 is fixed on the elastic plate 41.

[0080] Furthermore, a chute opening 22 is arranged on the inner ring 2. One end of the support plate 43 is fixed on a slider 25 in the chute opening 22. The inner ring 2 is of a hollow structure. A plurality of pushing devices 23 corresponding to the trigger devices 4 one by one are arranged in a cavity 20 inside the inner ring 2. A push rod 24 is connected to the pushing device 23. The other end of the push rod 24 is rotatably connected to a movable block on one side of the slider 25. The movable block is slidably connected to the slider 25. A pressure sensor is arranged in the pushing device 23. The pushing device 23 provides variable elastic force for the elastic plate 41 and detects the jitter of the cable 9 according to the pressure of the elastic plate 41.

[0081] Furthermore, the pushing device 23 is a hydraulic cylinder. When the pressure sensor in the pushing device 23 detects that the pressure received by the elastic plate 41 exceeds a preset value, it controls the pushing device 23 to push the slider 25 to slide, improving the elasticity of the elastic plate 41, so as to increase the clamping force on the cable 9 when the jitter is severe.

[0082] Furthermore, the pushing device 23 is a hydraulic cylinder, and its control logic and implementation method are as follows:

[0083] Sensor Detection and Signal Transmission: The pressure sensor inside the hydraulic cylinder monitors in real time the pressure transmitted by the elastic plate 41. The pressure sensor uses a high-precision and high-sensitivity pressure-sensitive element, which can quickly and accurately sense the minute changes in the pressure of the elastic plate 41. When the cable 9 vibrates, the elastic plate 41 will be correspondingly squeezed or stretched. The pressure sensor converts this pressure change into an electrical signal, and this electrical signal is processed by the signal conditioning circuit inside the sensor, such as amplification and filtering, to improve the quality and stability of the signal, and then is transmitted to the control unit through the data line;

[0084] Control Unit Signal Processing and Judgment: The control unit is the core of the entire system, usually using a high-performance microcontroller (MCU). After receiving the electrical signal transmitted by the pressure sensor, the control unit first performs analog-to-digital conversion on the signal to convert the analog signal into a digital signal for easy processing. Then, the control unit compares the currently detected pressure value with a pre-set pressure threshold, and this pre-set pressure threshold is accurately set according to factors such as the type, specification of the cable 9, and the actual application scenario, etc.;

[0085] Control Instruction Generation and Execution: If the control unit determines that the current pressure value exceeds the pre-set threshold, it means that the vibration of the cable 9 is relatively severe and the clamping force on the cable 9 needs to be increased. At this time, the control unit will generate corresponding control instructions according to the degree of pressure exceeding and the pre-set control algorithm, and the control instructions are transmitted to the solenoid valve of the hydraulic system through the control circuit;

[0086] The hydraulic system mainly consists of a hydraulic pump, an oil tank, a solenoid valve, and a hydraulic cylinder, etc. The solenoid valve precisely adjusts the flow rate and flow direction of the hydraulic oil according to the received control instructions. The hydraulic pump sucks the hydraulic oil from the oil tank and delivers it to the hydraulic cylinder at a certain pressure. When the solenoid valve opens the corresponding oil passage, the hydraulic oil enters the rodless cavity of the hydraulic cylinder, pushing the piston to move, and then pushing the slider 25 to slide within the chute opening 22 through the push rod 24;

[0087] Elastic Adjustment and Feedback Control: As the slider 25 slides, the position of the support plate 43 changes, thereby increasing the elasticity of the elastic plate 41, making the clamping force of the movable part 32 on the cable 9 increase. During this process, the pressure sensor continuously monitors the pressure change of the elastic plate 41 and feeds back the real-time pressure signal to the control unit. The control unit continuously adjusts the control instructions according to the feedback signal, forming a closed-loop control system to ensure that the clamping force on the cable 9 can be precisely adjusted according to the actual vibration situation, which not only ensures stable clamping of the cable 9 during severe vibration but also avoids damage to the cable 9 caused by excessive clamping;

[0088] The position of the pressure sensor can be installed at the part where the push rod 24 is connected to the pushing device 23;

[0089] Through the above control logic and implementation method, when the pressure sensor in the pushing device 23 detects that the pressure on the elastic plate 41 exceeds the preset value, it can accurately control the pushing device 23 to push the slider 25 to slide, improve the elasticity of the elastic plate 41, and thus increase the clamping force on the cable 9 when the shaking is severe.

[0090] Furthermore, the pushing device 23 is connected to a power source, and the power source is also connected to a photovoltaic power generation module. The photovoltaic power generation module includes a micro photovoltaic panel arranged on the outer ring 1.

[0091] Working principle: The inner ring 2 is rotatably connected to the middle of the outer ring 1. A plurality of spaced clamping bodies 3 are arranged on the outer ring 1. The spaced clamping body 3 is composed of a fixed part 31 fixed on the connecting plate 33 and a movable part 32 movably connected to the fixed part 31. There is a triggering device 4 corresponding to the spaced clamping body 3 on the inner ring 2. The driving device 5 on the inner side of the outer ring 1 can drive the inner ring 2 to rotate relative to the outer ring 1, and then make the triggering device 4 move relative to the spaced clamping body 3, so that the movable part 32 moves to clamp the cable 9. A chute opening 22 is arranged on the inner ring 2. One end of the support plate 43 of the triggering device 4 is fixed on the slider 25 in the chute opening 22. A pushing device 23 is arranged in the hollow structure of the inner ring 2. The pushing device 23 is connected to the slider 25 through a push rod 24. When the cable 9 shakes, the pressure sensor in the pushing device 23 detects the pressure change on the elastic plate 41. If it exceeds the preset value, the pushing device 23 pushes the slider 25 to slide, adjusts the position of the triggering device 4, and changes the supporting force on the cable 9, so as to flexibly adapt to the shaking of the cable. In addition, the hollow structure of the inner ring 2 reduces the overall weight of the spacer bar, which is convenient for high-altitude installation and transportation, and can drain water in rainy days to avoid water accumulation and corrosion, ensuring the normal use of the spacer bar and the reliability of power transmission.

[0092] In summary, for the multi-split spacer bar that is convenient for high-altitude installation, by designing the multi-split spacer bar into a structure composed of a relatively rotating outer ring 1 and inner ring 2, a plurality of spaced clamping bodies 3 are arranged on the outer ring 1. The spaced clamping body 3 is composed of a fixed part 31 and a movable part 32. The fixed part 31 is fixed on the outer ring 1, and the movable part 32 is movably connected to the fixed part 31. A triggering device 4 is fixed on the inner ring 2. During high-altitude installation, rotating the inner ring 2 drives the triggering device 4 to move, and the triggering device 4 pushes the movable part 32 to move, so that the movable part 32 and the fixed part 31 clamp a plurality of cables 9 at the same time, improving the installation efficiency, and realizing a modular structure design, achieving the effect of widely adapting to various cables 9, and effectively reducing the construction cost and time cost.

[0093] The multi-split spacer bar that facilitates high-altitude installation has a unique structural layout by designing the fixed part 31 as a semi-circular hook with an opening facing the center of the outer ring 1, rotatably connecting the movable part 32 inside the fixed part 31, and designing the triggering device 4 as a triangular plate with its fixed plate 42 pressing against the lower side of the movable part 32. When installing, the semi-circular hook-shaped fixed part 31 can quickly position the spacer bar at a suitable position on the cable 9. The triggering device 4 is composed of an elastic plate 41, a fixed plate 42, and a support plate 43. This structure can provide elastic support for the cable 9. When the cable 9 is displaced or shaken due to external factors, the elastic plate 41 deforms accordingly, playing a buffering role to prevent the cable 9 from being damaged due to rigid connection. It achieves the effects of facilitating the positioning of the cable 9, providing stable and elastic support for the cable 9, and improving the stability and safety of the cable 9 during operation.

[0094] The multi-split spacer bar that facilitates high-altitude installation realizes the function of adjustable supporting force by setting a chute opening 22 on the inner ring 2, fixing one end of the support plate 43 on the slider 25 in the chute opening 22, arranging a pushing device 23 inside the inner ring 2, and connecting the pushing device 23 to the slider 25 through a push rod 24. The pressure sensor in the pushing device 23 can push the slider 25 through the push rod 24 according to the jitter situation of the cable 9 to adjust the position of the triggering device 4 and change the supporting force on the cable 9. At the same time, the inner ring 2 adopts a hollow structure, which greatly reduces the overall weight of the spacer bar, facilitating high-altitude installation and transportation. The hollow structure can also drain water in rainy days to avoid damage to the spacer bar caused by water accumulation and corrosion. It achieves the effects of being able to flexibly adjust the supporting force according to actual needs, reducing weight, improving drainage performance, extending the service life of the spacer bar, and ensuring the reliability of power transmission.
