Description

Technical Field

[0001] This utility model belongs to the technical field of line de-icing equipment, and in particular relates to a centrifugal ice-breaking pendulum and a portable online operation platform. Background Technology

[0002] Currently, power transmission lines are highly susceptible to icing or frost during freezing disasters, seriously threatening the safe and stable operation of the power grid. To effectively address the problem of line icing, power departments generally employ manual de-icing or use specialized de-icing tools to break up ice on the lines. However, most existing line de-icing tools have relatively simple structures, relying mainly on impact or scraping for de-icing. Limited by their structure and force characteristics, they often suffer from low de-icing efficiency and insufficient de-icing force, especially when facing thick or hard frost formed in low-temperature environments, making effective breaking difficult. In addition, some existing de-icing devices rely on high energy consumption or complex drive mechanisms to improve de-icing effects, which not only increases the cost of equipment use and maintenance but also hinders portability and rapid operation in special environments.

[0003] Therefore, how to provide a device that is simple in structure, has good de-icing effect, low energy consumption, and can perform efficient de-icing is a technical problem that urgently needs to be solved in this field. Utility Model Content

[0004] To solve at least one of the above-mentioned technical problems, this utility model provides a centrifugal ice-breaking pendulum, comprising:

[0005] Pendulum, fixed arm, and drive assembly;

[0006] The tail of the pendulum is rotatably connected to the first end of the fixed arm;

[0007] The rotating shaft of the drive assembly is connected to the second end of the fixed arm;

[0008] The drive assembly drives the fixed arm to rotate via a rotary shaft, which in turn causes the pendulum to rotate centrifugally.

[0009] Furthermore, the pendulum includes: a hammer head and a hammer handle;

[0010] The hammer handle has a retractable first end that connects to the hammer head, and a second end that connects to the first end of the fixed arm.

[0011] Furthermore, a hammer sleeve is provided on the outside of the hammer head, and the hammer sleeve is provided with multiple protruding structures.

[0012] Furthermore, the hammer sleeve is made of hot-melt insulating material and is die-cast onto the hammer head.

[0013] Furthermore, a mounting groove is provided at the first end of the fixed arm; mounting holes are provided on both sides of the mounting groove.

[0014] The second end of the hammer handle is set in the mounting groove and can be rotatably connected to the first end of the fixed arm through a rivet bolt passing through the mounting hole.

[0015] Furthermore, the drive assembly includes: a drive element and a front cover disposed on the front side of the drive element;

[0016] The front cover is detachably connected to the drive unit and has a central shaft hole.

[0017] Furthermore, a bearing corresponding to the output shaft of the drive assembly is provided inside the shaft hole;

[0018] A damping ring is installed between the shaft hole and the bearing.

[0019] Furthermore, the drive assembly also includes a protective shell disposed around the side of the drive element;

[0020] An annular groove is provided inside the protective shell;

[0021] A shock-absorbing washer is installed inside the annular groove.

[0022] Furthermore, the drive assembly also includes: a drive board and a rear end cover;

[0023] The rear cover is detachable and located on the rear side of the drive unit;

[0024] The drive board is located between the rear cover and the protective shell, and is connected to the drive unit through the wiring holes on the protective shell.

[0025] A portable online operation platform, including any of the centrifugal ice-breaking pendulums mentioned above.

[0026] In this embodiment, a centrifugal ice-breaking pendulum is provided. During use, the drive assembly drives the fixed arm to rotate via a rotary shaft, causing the pendulum to rotate centrifugally to complete the ice-breaking process. For details, refer to... Figure 1 , Figure 2 and Figure 3Example: The working steps include multiple steps S1-S9. The fixed arm length is L2, the pendulum length is L1, the force provided by the rotating shaft is F, and the hammering force of the pendulum is F2. In stages S1 to S5, the pendulum is lifted: because the fixed arm and pendulum of the centrifugal ice-breaking pendulum actually form two mutually rotating links, this two-segment chain structure gradually overlaps during the lifting stage, and the torque radius gradually decreases from L1+L2, reducing the load on the drive components and improving the system's working stability and energy efficiency. In stages S6 to S9, the pendulum is thrown and struck: at this time, with the help of centrifugal force, the two segments of the pendulum chain structure gradually unfold, the torque radius gradually increases, returning to L1+L2, and generating a "whiplash effect"-like motion characteristic at the moment of unfolding, thus achieving a multiplier effect of the hammering force under limited drive power conditions. The hammering force F2 amplifies the force F provided by the rotating shaft. Simultaneously, the gravitational acceleration of the pendulum itself generates an instantaneous rigid impact on the ice, increasing the ice-breaking force under fixed power, significantly improving ice-breaking efficiency, reducing energy consumption, and extending ice-breaking endurance. Furthermore, because the radius of motion of this two-segment chain structure is variable, it is less likely to be restricted by obstacles during operation. Optionally, the drive component uses a DC motor in conjunction with battery power for more flexible deployment and improved applicability. In summary, this utility model provides a centrifugal ice-breaking pendulum with a simple structure, good de-icing effect, low energy consumption, and efficient de-icing capability.

[0034] This utility model provides a centrifugal ice-breaking pendulum, for reference. Figure 1 It includes: pendulum 3, fixed arm 1 and drive assembly;

[0035] The tail of the pendulum 3 is rotatably connected to the first end of the fixed arm 1;

[0036] The rotating shaft of the drive assembly is connected to the second end of the fixed arm 1;

[0037] The drive assembly drives the fixed arm 1 to rotate via the rotary shaft, which in turn causes the pendulum 3 to rotate centrifugally.

[0038] In this embodiment, a centrifugal ice-breaking pendulum is provided. During use, the drive assembly drives the fixed arm to rotate via a rotary shaft, causing the pendulum to rotate centrifugally to complete the ice-breaking process. For details, refer to... Figure 1 , Figure 2 and Figure 3Example: The working steps include multiple steps S1-S9. The fixed arm length is L2, the pendulum length is L1, the force provided by the rotating shaft is F, and the hammering force of the pendulum is F2. In stages S1 to S5, the pendulum is lifted: because the fixed arm and pendulum of the centrifugal ice-breaking pendulum actually form two mutually rotating links, this two-segment chain structure gradually overlaps during the lifting stage, and the torque radius gradually decreases from L1+L2, reducing the load on the drive components and improving the system's working stability and energy efficiency.

Furthermore, because the radius of motion of this two-segment chain structure is variable, it is less likely to be restricted by obstacles during operation. Optionally, the drive component uses a DC motor in conjunction with battery power for more flexible deployment and improved applicability. In summary, this utility model provides a centrifugal ice-breaking pendulum with a simple structure, good de-icing effect, low energy consumption, and efficient de-icing capability.

[0039] Preferred, Reference Figure 1 The pendulum 3 includes a hammer head and a hammer handle.

[0040] The hammer handle has a retractable first end that connects to the hammer head, and a second end that connects to the first end of the fixed arm 1.

[0041] In this embodiment, by adjusting the length of the hammer handle, the length of the pendulum can be freely adjusted according to the spatial conditions of different working environments or the required ice-breaking force. The adjusted hammer handle length facilitates safe operation in narrow or obstacle-filled environments and, where space permits, increases the striking radius of the pendulum head, thereby improving the ice-breaking effect. For example, the hammer handle includes an inner sleeve and an outer sleeve. The inner sleeve can slide on the outer sleeve, and after being adjusted to a predetermined position, its length is locked by a pin or positioning pin passing through a corresponding insertion hole. Optionally, the hammer handle can also be a snap-fit ​​limiting length adjustment mechanism, a threaded tightening length adjustment mechanism, or other mechanical structures capable of length extension and retraction.

[0042] Preferred, Reference Figure 1 A hammer sleeve 4 is provided on the outside of the hammer head, and multiple protrusions are provided on the hammer sleeve 4.

[0043] In this embodiment, by adding a hammer sleeve to the outside of the hammer head and setting multiple protrusions on the hammer sleeve, the impact area and friction when the hammer head contacts the ice layer can be effectively increased, thereby enhancing the ice-breaking effect of the hammer head. More preferably, the protrusions are cone-shaped, triangular, or prismatic, etc., with sharp edges, to further reduce the hammering area and increase the hammering pressure.

[0044] Preferably, the hammer sleeve is made of hot-melt insulating material and is die-cast onto the hammer head.

[0045] In this embodiment, the use of a hammer sleeve made of hot-melt insulating material effectively improves the impact resistance and wear resistance of the hammer head. Simultaneously, the application of die-casting technology ensures a tighter bond between the hammer sleeve and the hammer head, reducing gaps and enhancing the overall strength and stability of the structure. The hot-melt insulating material also effectively isolates current, preventing electrical accidents caused by current contact, making it particularly suitable for live-line work or environments requiring current isolation. Optionally, the hot-melt insulating material is polyamide plastic.

[0046] Preferred, Reference Figure 1 The first end of the fixed arm 1 is provided with a mounting groove; mounting holes are provided on both sides of the mounting groove.

[0047] The second end of the hammer handle is set in the mounting groove and can be rotatably connected to the first end of the fixed arm 1 by a rivet bolt 2 that passes through the mounting hole.

[0048] In this embodiment, a mounting groove is provided at the first end of the fixed arm, and mounting holes are provided on both sides of the mounting groove to provide a stable mounting position for the second end of the hammer handle. The hammer handle is connected to the fixed arm by riveting bolts passing through the mounting holes, so that a reliable rotational connection can be achieved between the hammer handle and the fixed arm, avoiding loosening or damage caused by external forces during use, and increasing the durability and safety of the structure.

[0049] Preferred, Reference Figure 1 The drive assembly includes: a drive component 8 and a front cover 5 disposed on the front side of the drive component 8;

[0050] The front cover 5 is detachably connected to the drive unit 8, and has a shaft hole in the center.

[0051] In this embodiment, a removable front cover is provided on the front side of the drive component 8. This effectively prevents splashed ice from being drawn into the drive component 8 during the de-icing process and also prevents external substances (such as dust and debris) from intruding, ensuring the long-term stable operation of the drive assembly. A shaft hole is provided in the center of the front cover to ensure that the rotation shaft of the drive assembly can be stably and accurately connected to the fixed arm, improving the operational stability of the device. The drive component 8 can be a high-power DC motor to provide rotational drive for the rotation shaft of the drive assembly.

[0052] Preferred, Reference Figure 1 A bearing 7 corresponding to the output shaft of the drive assembly is provided in the shaft hole;

[0053] A shock-absorbing ring 6 is provided between the shaft hole and the bearing 7.

[0054] In this embodiment, the bearing provides support for the aforementioned rotating shaft, ensuring its smooth rotation. A damping ring is installed between the shaft hole and the bearing. This reduces vibration and impact forces generated during the operation of the drive assembly, and reduces vibration caused by the pendulum colliding with ice during de-icing. Furthermore, the damping ring can deform to act as a seal, preventing ice slag from melting and entering the drive component 8 during de-icing, thus significantly improving the device's service life.

[0055] Preferred, Reference Figure 1 The drive assembly also includes a protective shell 10 disposed around the side of the drive element 8;

[0056] An annular groove is provided inside the protective shell 10;

[0057] A shock-absorbing washer 9 is installed inside the annular groove.

[0058] In this embodiment, a protective shell is added to the side of the drive component 8 to provide physical protection for it. An annular groove is provided inside the protective shell, and a shock-absorbing washer is placed within the annular groove. This further absorbs the vibration or impact force generated by the drive component 8 during operation, reducing the transmission of vibration to other components, thereby improving the stability of the entire system and reducing device noise. More preferably, there are three annular grooves, evenly spaced inside the protective shell, to ensure that vibration of the drive component 8 is eliminated at the front, middle, and rear positions.

[0059] Preferred, Reference Figure 1 The drive components also include: a drive board 11 and a rear cover 12;

[0060] The rear cover 12 is detachably located on the rear side of the drive unit 8;

[0061] The drive board is located between the rear cover and the protective shell 10, and is connected to the drive component 8 through the wiring hole on the protective shell 10.

[0062] In this embodiment, a rear end cover is added to the rear side of the drive assembly, and the drive plate is disposed between the rear end cover and the protective shell, and connected to the drive component 8. On the one hand, this further improves the protection of the drive component 8; on the other hand, this rear-mounted drive plate structure can reduce the impact and vibration generated by the movement of the front pendulum, and reduce the influence on the internal circuit of the drive plate, thereby improving the stability of the device operation. The drive component 8 is used to connect to an external power source, receive remote control signals, and realize the forward and reverse, fast and slow rotation of the drive component 8. It is worth noting that the key to this application is to provide a centrifugal ice-breaking pendulum that achieves ice removal from a mechanical structure. The specific control process, action time, speed adjustment, and forward and reverse rotation can be implemented by a programmable logic device such as a PLC, and will not be elaborated here.

[0063] A portable online mobile operation platform, including any of the centrifugal ice-breaking pendulums mentioned above.

[0064] In this embodiment, the portable online work platform integrates any of the aforementioned centrifugal ice-breaking pendulums. Utilizing the platform's autonomous movement along power lines or other lines, the centrifugal ice-breaking pendulums can perform de-icing operations without manual climbing or approach. This frees de-icing operations from manual location constraints, enabling coverage of a wide range of power lines and improving de-icing efficiency and operational safety. It further reduces de-icing costs, increases efficiency and equipment endurance, and meets the demand for efficient de-icing in complex environments and severe weather. Optionally, the portable online mobile work platform can be an ice-breaking robot. Through the impact of the centrifugal ice-breaking pendulums, combined with the robot's mobility, it can quickly break ice, clear obstacles, or remove other attachments.

[0065] The aforementioned portable online operation platform is based on the centrifugal ice-breaking pendulum, and its technical effects and features are not elaborated further here. The above embodiments merely illustrate several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model.
