Description

Technical Field

[0001] The invention relates to the technical field of multi-split spacer bars, in particular to a multi-split spacer bar that is convenient for high-altitude installation. Background Art

[0002] Multi-split spacers play a vital role in power transmission lines. Their main function is to fix multi-split conductors, prevent them from whipping and dancing with each other, maintain the spacing between each split conductor, and ensure the safe and stable operation of power transmission lines. With the continuous development of power transmission technology, higher requirements are placed on the performance and installation convenience of multi-split spacers.

[0003] In the prior art, there are already various types of multi-split spacers. For example, the multi-split spacer disclosed in the patent document with patent publication number CN221428549U adopts a traditional structural design, in which multiple clamps are fixed on the cable by bolts and other connectors. Although this structure can fix the cable to a certain extent, it has some obvious shortcomings in practical applications.

[0004] In terms of installation, the installation process of traditional spacers is relatively cumbersome. Installers need to tighten multiple bolts one by one, which not only consumes a lot of time and manpower, but also makes the operation difficult and the installation efficiency low in a high-altitude working environment. In addition, since bolt connections require precise alignment and tightening torque control, improper installation can easily lead to uneven clamping force of the clamp on the cable, affecting the fixing effect of the spacer and even causing safety hazards.

[0005] In terms of structural design, the structure of traditional spacers is relatively fixed and difficult to adapt to the needs of cables with different split numbers and different spacings. When the transmission line needs to be modified or adjusted, the entire spacer often needs to be replaced, which increases the cost and construction difficulty. Summary of the invention

[0006] 1. Technical issues to be resolved In view of the shortcomings of the prior art, the present invention provides a multi-split spacer bar that is easy to install at high altitude. The spacer bar is arranged as an inner and outer ring structure that is socketed together and rotatable with each other, and half of a clamp is arranged on the inner and outer rings respectively. When the inner and outer rings are rotated, the clamp can synchronously clamp the cables. This design effectively simplifies the installation process. The installer only needs to rotate the inner and outer rings to complete the simultaneous fixation of multiple cables. There is no need to tighten the bolts one by one like traditional spacers. This greatly improves the installation efficiency and reduces the installation difficulty. It solves the problem in the prior art that the installer needs to tighten multiple bolts one by one, which consumes a lot of time and manpower, and the operation is difficult and the installation efficiency is low in the high-altitude working environment.

[0017] (III) Beneficial effects Compared with the prior art, the present invention provides a multi-split spacer that is easy to install at high altitude, and has the following beneficial effects: 1. The multi-split spacer bar that is easy to install at high altitude is designed to be a structure consisting of an outer ring and an inner ring that rotate relatively, and a plurality of spacer clamps are arranged on the outer ring. The spacer clamps consist 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 trigger device is fixed on the inner ring. When installing at high altitude, the inner ring is rotated to drive the trigger device to move, and the trigger device moves against the movable part, so that the movable part and the fixed part clamp multiple cables at the same time, thereby 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.

[0018] 2. The multi-split spacer that is easy to install at high altitude has a fixed part designed as a semi-ring hook with an opening facing the center of the outer ring, and the movable part is rotatably connected in the fixed part. At the same time, the trigger device is designed as a triangular plate, and its fixed plate is on the lower side of the movable part, realizing a unique structural layout. The semi-ring hook-shaped fixed part can quickly position the spacer at the appropriate position of the cable during installation. The trigger device is composed of an elastic plate, a fixed plate and a support plate. This structure can provide elastic support for the cable. When the cable is displaced or shaken by external factors, the elastic plate is deformed accordingly, playing a buffering role to prevent the cable from being damaged due to rigid connection.

At the same time, the inner ring adopts a hollow structure, which greatly reduces the overall weight of the spacer bar and is convenient for high altitude installation and transportation. The hollow structure can also drain water on rainy days to prevent the accumulated water from corroding the spacer bar and causing damage to the spacer bar, thereby achieving the effect of flexibly adjusting the supporting force according to actual needs, reducing the weight, and improving the drainage performance, thereby extending the service life of the spacer bar and ensuring the reliability of power transmission.

Round 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.

[0044] Further, the driving device 5 comprises: A driving column 51, the front and rear ends of which are rotatably connected to the front and rear plates of the outer ring 1, wherein 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; A cover plate 52 is detachably fixed on the outer ring 1 and is used to wrap the driving column 51. A locking block 53 is fixed in the middle of the cover plate 52. The outer side of the driving column 51 is provided with round teeth that mesh with the inner side of the inner ring 2. The round teeth are distributed in the front and rear sections of the driving column 51. No round teeth are provided in the middle position of the driving column 51. In the unlocked state, the locking block 53 is located in the middle position of the driving column 51, and the rotation of the driving column 51 drives the inner ring 2 to rotate. In the locked state, the driving column 51 is slid by knocking one end of the driving column 51, so that the locking block 53 is stuck on the round teeth of the driving column 51, thereby locking the driving column 51 and the inner ring 2.

[0045] It is further provided that one end of the movable part 32 is rotatably connected to the fixed part 31, the movable part 32 is a C-shaped structure, an inner recess 321 is provided on the inner side of the movable part 32, and an outer protrusion 322 is provided on the outer side, the inner recess 321 is used to squeeze the cable 9, and the outer protrusion 322 is used to support the elastic plate 41, and an insulating rubber pad is provided on the surface of the inner recess 321.

[0046] Furthermore, the outer side of the inner ring 2 is provided with a scale mark, and the position of the outer ring 1 corresponding to the scale mark is provided with an indicator arrow. By observing the relative position of the scale mark and the indicator arrow, the rotation angle of the inner ring 2 relative to the outer ring 1 can be intuitively judged, thereby accurately controlling the clamping degree of the spacer clamp 3 on the cable 9.

[0047] Furthermore, a built-in level is provided inside the inner ring 2, which can be directly viewed from the outside through a transparent observation window, so as to help operators quickly determine whether the inner ring and the spacer clamp are in a horizontal state during high-altitude installation, ensure uniform cable clamping, and avoid uneven local force on the cable due to tilting.

[0048] Furthermore, a flexible rubber buffer layer is provided at the edge of the movable portion 32. During the cable clamping process, the buffer layer can effectively avoid hard friction damage between the movable portion and the cable, while enhancing the adaptability and fit to cables of different diameters.

[0049] Furthermore, the locking block 53 of the driving device 5 is provided with an intelligent sensing component. When the locking block is locked with the spherical teeth of the driving column 51, if the spacer bar is detected to have abnormal shaking or force changes, the intelligent sensing component can automatically unlock, allowing the inner ring 2 to rotate a certain angle relative to the outer ring 1, playing a buffering and protective role. After the abnormal situation is eliminated, it can automatically re-lock, effectively avoiding damage to the spacer bar and 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 to connect the lines of the built-in sensor and the external monitoring equipment to achieve signal transmission.

[0050] Furthermore, a sealed dust cover is provided between the outer ring 1 and the inner ring 2, which can effectively prevent impurities such as dust and sand from entering the rotating connection part, reduce wear, and extend the overall maintenance period and service life of the spacer rod.

[0052] Furthermore, the outer surface of the outer ring 1 is provided with a plurality of anti-skid protrusions to increase the friction when the height workers hold it, thereby preventing the spacer rods from slipping during the installation process.

[0053] Furthermore, the fixed portion 31 and the movable portion 32 of the spacer clamp 3 are made of high-strength aluminum alloy, which reduces the overall weight while ensuring the structural strength, and facilitates high-altitude installation operations.

[0054] Working principle: Based on the relative rotation structure of the outer ring 1 and the inner ring 2. A plurality of spacer clamps 3 are provided on the outer ring 1, and the spacer clamps 3 are 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 can be movably connected to the fixed part 31. A trigger device 4 is fixed on the upper side of the inner ring 2. During the high-altitude installation operation, the inner ring 2 is rotated, and the rotation of the inner ring 2 drives the trigger device 4 to move synchronously. Since the fixed plate 42 of the trigger device 4 (triangle plate) is against the lower side of the movable part 32, the trigger device 4 will push the movable part 32 when it moves, so that it works together with the fixed part 31, thereby clamping multiple cables 9. Among them, the fixed part 31 is designed as a semi-ring hook with its opening facing the center of the outer ring 1, which can quickly locate the appropriate position of the spacer rod and the cable 9 at the initial installation. The structure composed of the elastic plate 41, the fixing plate 42 and the supporting plate 43 of the trigger device 4 not only ensures the triggering and pushing of the movable part 32 under normal conditions, but also the elastic plate 41 can deform and play a buffering role when the cable 9 is displaced or shaken by external factors, thereby preventing the cable 9 from being damaged due to the rigid connection. In this way, the spacer realizes efficient installation and modular adaptation of different cables, while ensuring the stability and safety of the operation of the cable 9.

[0055] Embodiment 2: This embodiment provides a multi-split spacer rod that is easy to install at high altitude and has the following technical features.

[0056] See also Figure 11-Figure 15 A multi-split spacer bar that is easy to install at high altitude, 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 spacer clip 3 are respectively fixed on two connecting plates 33, the two connecting plates 33 are respectively fixed on the front and rear plates in the inner ring 2, any 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; A plurality of trigger devices 4 corresponding to the spacer clamps 3 are fixedly arranged on the inner ring 2, and a driving device 5 is also arranged on the inner side of the outer ring 1. Round 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, it drives the trigger devices 4 to move relative to the spacer clamps 3, so that the movable part 32 moves to clamp the cable 9.

[0057] It is further provided that, in any spacing clamp body 3, the fixing portion 31 is a semi-ring hook, and the opening of the fixing portion 31 faces the center of the outer ring 1; The movable part 32 is rotatably connected to the fixed part 31. A central groove 311 is provided at the center of the fixed part 31. The movable part 32 is rotatably connected in the central groove 311. The trigger device 4 is a triangular plate, and the three sides of the trigger device 4 are an elastic plate 41, a fixed plate 42 and a support plate 43. The fixed plate 42 is fixed on the inner ring 2, and the fixed plate 42 is pressed against the lower side of the movable part 32. One end of the support plate 43 is fixed on the elastic plate 41.

[0058] It is further provided that a slide groove opening 22 is provided on the inner ring 2, one end of the support plate 43 is fixed on the slider 25 in the slide groove opening 22, the inner ring 2 is a hollow structure, and a plurality of pushing devices 23 corresponding to the trigger device 4 are provided in the cavity 20 in the inner ring 2, and a push rod 24 is connected to the pushing device 23, and the other end of the push rod 24 is rotatably connected to a movable block on one side of the slider 25, and the movable block is slidably connected to the slider 25, and a pressure sensor is provided in the pushing device 23, and the pushing device 23 provides a variable elastic force for the elastic plate 41 and detects the vibration of the cable 9 according to the pressure of the elastic plate 41.

[0059] It is further configured that the pushing device 23 is a hydraulic cylinder. When the pressure sensor in the pushing device 23 detects that the elastic plate 41 is subjected to a pressure exceeding a preset value, the pushing device 23 is controlled to push the slider 25 to slide, thereby increasing the elasticity of the elastic plate 41, thereby increasing the clamping force on the cable 9 when the shaking is severe.

[0060] It is further provided that the pushing device 23 is a hydraulic cylinder, and its control logic and implementation are as follows: Sensor detection and signal transmission: The pressure sensor inside the hydraulic cylinder monitors the pressure transmitted by the elastic plate 41 in real time. The pressure sensor uses a high-precision, high-sensitivity pressure-sensitive element, which can quickly and accurately sense the slight changes in the pressure of the elastic plate 41. When the cable 9 shakes, the elastic plate 41 will be squeezed or stretched accordingly. The pressure sensor converts this pressure change into an electrical signal, which is amplified, filtered, and processed by the signal conditioning circuit inside the sensor to improve the quality and stability of the signal, and then transmitted to the control unit through the data line; Control unit signal processing and judgment: The control unit is the core of the entire system, and usually adopts 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, converting the analog signal into a digital signal for easy processing. Then, the control unit compares the currently detected pressure value with the preset pressure threshold. This preset pressure threshold is accurately set according to factors such as the type and specification of the cable 9 and the actual application scenario; Generation and execution of control instructions: If the control unit determines that the current pressure value exceeds the preset threshold, it means that the vibration of the cable 9 is relatively severe and the clamping force of the cable 9 needs to be increased. At this time, the control unit will generate corresponding control instructions according to the degree of pressure excess and the preset control algorithm. The control instructions are transmitted to the solenoid valve of the hydraulic system through the control circuit; The hydraulic system is mainly composed of a hydraulic pump, an oil tank, a solenoid valve and a hydraulic cylinder. The solenoid valve accurately adjusts the flow and direction of the hydraulic oil according to the control command received. The hydraulic pump draws 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 channel, the hydraulic oil enters the rodless chamber of the hydraulic cylinder, pushing the piston to move, and then pushing the slider 25 to slide in the slide groove 22 through the push rod 24; Elasticity 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, so that the clamping force of the movable part 32 on the cable 9 increases. In this process, the pressure sensor will continuously monitor the pressure change of the elastic plate 41 and feed back the real-time pressure signal to the control unit. The control unit continuously adjusts the control command according to the feedback signal to form a closed-loop control system to ensure that the clamping force of the cable 9 can be accurately adjusted according to the actual shaking situation, which not only ensures that the cable 9 can be stably clamped when the shaking is severe, but also avoids damage to the cable 9 caused by excessive clamping; The pressure sensor may be installed at the portion where the push rod 24 and the pushing device 23 are connected; Through the above-mentioned 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, thereby increasing the elasticity of the elastic plate 41, thereby increasing the clamping force of the cable 9 when the shaking is severe.

[0061] It is further provided that the pushing device 23 is connected to a power source, and the power source is further connected to a photovoltaic power generation module, and the photovoltaic power generation module includes a micro photovoltaic panel arranged outside the outer ring 1.

[0062] Working principle: The outer ring 1 is connected to the inner ring 2 in a rotating manner in the middle. The outer ring 1 is provided with a plurality of spacer clamps 3. The spacer clamps 3 are composed of a fixed part 31 fixed on the connecting plate 33 and a movable part 32 movably connected to the fixed part 31. The inner ring 2 is provided with a trigger device 4 corresponding to the spacer clamps 3. 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, thereby moving the trigger device 4 relative to the spacer clamps 3, so that the movable part 32 moves to clamp the cable 9. The inner ring 2 is provided with a slide groove 22. One end of the support plate 43 of the trigger device 4 is fixed on the slider 25 in the slide groove 22. The hollow structure of the inner ring 2 is provided with a push device 23, and the push device 23 is connected to the slider 25 through a push rod 24. When the cable 9 shakes, the pressure sensor in the push device 23 detects the pressure change on the elastic plate 41. If it exceeds the preset value, the push device 23 pushes the slider 25 to slide, adjusts the position of the trigger 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, making it easier to install and transport at high altitudes. It can also drain water on rainy days to avoid corrosion caused by accumulated water, thus ensuring the normal use of the spacer bar and the reliability of power transmission.

[0063] To sum up, the multi-split spacer bar which is easy to install at high altitude is designed as a structure consisting of an outer ring 1 and an inner ring 2 which rotate relatively, and a plurality of spacer clamps 3 are arranged on the outer ring 1, the spacer clamps 3 are composed of a fixed part 31 and a movable part 32, the fixed part 31 is fixed on the outer ring 1, the movable part 32 is movably connected to the fixed part 31, and a trigger device 4 is fixed on the inner ring 2. When installing at high altitude, the trigger device 4 is driven to move by rotating the inner ring 2, and the trigger device 4 moves against the movable part 32, so that the movable part 32 and the fixed part 31 clamp multiple cables 9 at the same time, thereby improving the installation efficiency and realizing a modular structural design, achieving the effect of being widely adaptable to various types of cables 9, and effectively reducing the construction cost and time cost.

[0064] The multi-split spacer that is easy to install at high altitude has a unique structural layout by designing the fixed part 31 as a semi-ring hook with an opening facing the center of the outer ring 1, and the movable part 32 is rotatably connected in the fixed part 31. At the same time, the trigger device 4 is designed as a triangular plate, and its fixed plate 42 is on the lower side of the movable part 32. The semi-ring hook-shaped fixed part 31 can quickly position the spacer at a suitable position of the cable 9 during installation. The trigger 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 by external factors, the elastic plate 41 is deformed accordingly, playing a buffering role, and preventing the cable 9 from being damaged due to rigid connection. The cable 9 is conveniently positioned, and stable and elastic support is provided for the cable 9, thereby improving the stability and safety of the operation of the cable 9.

[0065] The multi-split spacer bar, which is easy to install at high altitude, has a slot opening 22 on the inner ring 2, one end of the support plate 43 is fixed on the slider 25 in the slot opening 22, a pushing device 23 is arranged in the inner ring 2, and the pushing device 23 is connected to the slider 25 through a push rod 24, thereby realizing the function of adjustable supporting force. The pressure sensor in the pushing device 23 can push the slider 25 through the push rod 24 according to the shaking of the cable 9, adjust the position of the trigger 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 and is convenient for high altitude installation and transportation. The hollow structure can also drain water on rainy days to prevent the accumulated water from causing corrosion and other damages to the spacer bar, thereby achieving the effect of not only being able to flexibly adjust the supporting force according to actual needs, but also reducing the weight and improving the drainage performance, thereby extending the service life of the spacer bar and ensuring the reliability of power transmission.
