Description

Technical Field

[0001] This application belongs to the field of power transmission and transformation line technology, specifically relating to a striking mechanism and a power transmission and transformation line de-icing device. Background Technology

[0002] The de-icing device for power transmission lines, with announcement number CN218829023U, has a core structure consisting of an outer casing. The casing contains symmetrically arranged cable wheels to ensure stable movement and operation of the device on the power transmission line. The de-icing mechanism of this device is achieved through two coordinated parts: first, a hot air heater is used to bake the ice layer on the line, accelerating its melting; second, a scraper is used to remove the melted ice from below the power transmission line, completing the de-icing process.

[0003] However, this device has limitations in its de-icing method, relying solely on hot air baking to melt the ice. When encountering thick ice layers in actual operations, hot air baking alone is insufficient to quickly penetrate the thick ice and achieve efficient melting, leading to a significant decrease in the overall ice melting rate and ultimately negatively impacting the de-icing efficiency of power transmission lines.

Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0030] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0031] See also Figures 1 to 6 As shown, according to a first aspect of the embodiments of this application, a striking mechanism is provided for use in a de-icing device. The striking mechanism includes a transmission assembly, a reset part 11, and a striking part 9. The transmission assembly is disposed on the de-icing device, and the striking part 9 is disposed on the transmission assembly. The transmission assembly is used to drive the striking part 9 to move in a first direction. The reset part 11 includes a first end and a second end. The first end of the reset part 11 is connected to the transmission assembly, and the second end of the reset part 11 is connected to the striking part 9, so that when the transmission assembly loses power, it drives the striking part 9 to move in a second direction.

[0032] By setting a striking mechanism on the de-icing device, the striking part 9 is driven to move in the first direction by the transmission component of the striking mechanism, and the striking part 9 is driven to move in the second direction by the reset part 11, continuously striking the ice layer on the power transmission line. At the same time, in conjunction with the hot air drying machine of the de-icing device itself, the efficiency of de-icing the power transmission line is accelerated.

[0033] Among them, the striking part 9 is a striking hammer structure, which is the actuator that directly contacts the ice layer and realizes the breaking function.

[0034] Specifically, the striking part 9 includes a hammer body and a connecting arm. The connecting arm and the hammer body are integrally formed to create the striking part 9, ensuring overall rigidity and preventing breakage during striking. The connecting arm is a metal rod, and the hammer body is a hemispherical or wedge-shaped metal block. The contact end between the hammer body and the ice layer adopts a rounded transition design to prevent sharp edges from scratching the insulation layer of the power transmission line.

[0035] A more specific embodiment is as follows: when the transmission assembly drives the striking part 9 to move in the first direction (upward swinging), the striking part 9 pulls the second end of the reset part 11 and the connecting end of the striking part 9 to rotate upward synchronously, while the first end of the reset part 11 remains stationary, causing the reset part 11 to undergo torsional deformation and gradually store elastic potential energy; when the transmission assembly loses power, the elastic potential energy of the reset part 11 begins to be released, pushing the second end of the reset part 11 to rotate in the opposite direction, driving the striking part 9 to move rapidly in the second direction (downward swinging direction, i.e., the striking direction) until the reset part 11 returns to its natural state. At this time, the striking part 9 will generate an impact force on the ice layer on the transmission line (the striking force is determined by the torque of the reset part 11 and the weight of the striking part 9), completing one striking action; then the cycle of energy storage → elastic release → striking is repeated to achieve continuous ice breaking operation.

[0036] In another embodiment, the transmission assembly includes at least two mounting plates 10, which are disposed on the de-icing device so that the striking mechanism is mounted on the de-icing device. The mounting plates 10 serve as the connecting and supporting foundation of the transmission assembly, acting as the core carrier for achieving a rigid connection between the striking mechanism and the de-icing device, while also providing a stable mounting reference for the transmission assembly and the reset part 11. The mounting plates 10 have two functions: first, a fixed connection function, precisely connecting with the de-icing device to fix the entire striking mechanism onto it, ensuring the coordination between the striking action and the device's movement; second, a rotational support function, using a built-in bearing structure to provide low-friction, high-precision support for the rotation of the transmission assembly, preventing radial runout from causing the striking action to deviate and ensuring the stability of ice breaking.

[0037] In this embodiment, the mounting plate 10 consists of two square plates symmetrically arranged on the outside of the de-icing device, with an installation space formed between the two mounting plates 10.

[0038] In another embodiment, the transmission assembly further includes a rotating shaft, a connecting shaft, a first gear 12 and a second gear 13. The mounting plate 10 is provided with a through hole, and the rotating shaft is installed in the through hole and rotates relative to the mounting plate 10. The first gear 12 is sleeved at the end of the rotating shaft, and the connecting shaft is provided on the de-icing device. The second gear 13 that meshes with the first gear 12 is provided at the end of the connecting shaft.

[0039] The striking part 9 is located in the middle of the rotating shaft, and the reset part 11 is sleeved on the rotating shaft. The first end of the reset part 11 is fixed to the side wall of the mounting plate 10, and the second end of the reset part 11 is fixed to the striking part 9.

[0040] The mounting plate 10 has a through hole, and the rotating shaft is installed in the through hole and rotates relative to the mounting plate 10. That is, the mounting plate 10 is used to support the rotating shaft, the rotating shaft is installed on the through hole through a bearing, and the rotating shaft can rotate relative to the mounting plate 10, thereby driving the striking part 9 to move in the first direction.

[0041] The first gear 12 is sleeved at the end of the rotating shaft, and the connecting shaft is set on the de-icing device. The second gear 13 that meshes with the first gear 12 is set at the end of the connecting shaft. In other words, in this embodiment, the connecting shaft is a power input shaft. The rotation of the connecting shaft drives the second gear 13 to rotate, which in turn drives the first gear 12 that meshes with the second gear 13 to rotate, thereby driving the striking part 9 to rotate together with the rotating shaft.

[0042] The striking part 9 is located in the middle of the rotating shaft, and the reset part 11 is sleeved on the rotating shaft. The first end of the reset part 11 is fixed to the side wall of the mounting plate 10, and the second end of the reset part 11 is fixed to the striking part 9. That is, the connecting arm of the striking part 9 is welded to the rotating shaft away from the hammer body to ensure that the two are relatively fixed during the striking process. The reset part 11 is a torsion spring. In this embodiment, there are two springs, which are respectively sleeved on the rotating shafts on both sides of the striking part 9. The torsion arm at the first end of the reset part 11 is installed on the mounting plate 10 by a fixing pin, and the torsion arm at the second end is installed on the striking part 9 by a fixing pin.

[0043] In another embodiment, the second gear 13 has at least one toothless region along the circumferential direction of its rim.

[0044] The design of at least one toothless section along the circumference of the rim of the second gear 13 is crucial for achieving the reciprocating striking motion of the striking mechanism. The arc length of this toothless section typically accounts for 2 / 3 to 3 / 4 of the total arc length, precisely matching the elastic potential energy release cycle of the reset section 11. This provides a necessary power interruption window for the reverse reset action of the striking section 9, while simultaneously enabling coordinated control of the striking frequency and the travel speed of the de-icing device. This is the core element ensuring the stable and efficient operation of the striking mechanism.

[0045] The specific implementation process is as follows: During the meshing stage, the toothed area operates. When the toothed area of ​​the second gear 13 meshes with the first gear 12, rotational power is transmitted to the first gear 12 through gear meshing, thereby driving the rotating shaft and the striking part 9 to swing in the first direction (upward). Simultaneously, the reset part 11 is twisted to store energy. During this stage, the toothless area does not participate in the transmission, ensuring stable power transmission to complete energy storage. During the disengagement stage, the toothless area operates. As the second gear 13 continues to rotate, its toothless area gradually turns towards the first gear 12, interrupting the gear meshing relationship and causing the transmission component to lose power input. At this time, the elastic potential energy of the reset part 11 begins to be released, driving the striking part 9 to swing rapidly in the second direction (downward), completing the striking action on the ice layer. The existence of the toothless area prevents the second gear 13 from continuously pushing the first gear 12 to rotate, providing a resistance-free window for the reset part 11 to reverse drive, ensuring the smooth implementation of the striking mechanism's action.

[0046] In another embodiment, the striking mechanism further includes a counterweight assembly comprising a counterweight block 16 and a connecting rod 17. One end of the connecting rod 17 is connected to a rotating shaft, and the counterweight block 16 is disposed on the other end of the connecting rod 17. The counterweight assembly ensures that the de-icing device is in a balanced state when de-icing along the power transmission line, preventing it from tilting and slipping off the power transmission line.

[0047] The second aspect of this application provides a de-icing device for power transmission and transformation lines, including the striking mechanism described in any one of the above, and further including at least two wire guide wheel assemblies, an outer casing 1 and a hot air baking machine 4. The hot air baking machine 4 is disposed on the top of the outer casing 1, the wire guide wheel assembly is disposed on the bottom of the outer casing 1, and the striking mechanism is disposed on the side wall of the outer casing 1 and connected to one of the wire guide wheel assemblies.

[0048] The outer shell 1 has an installation port at the top center, and the hot air baking machine 4 is installed at the installation port and fixed to the top of the outer shell 1 with bolts. The hot air baking machine 4 is used to bake the ice layer after it has been knocked, so that the ice layer melts quickly and achieves the purpose of quick de-icing.

[0049] The cable wheel assembly is located at the bottom of the outer casing 1. In other words, the two cable wheel assemblies are located one after the other at the bottom of the outer casing 1 along the moving direction of the de-icing device. The de-icing device is secured to the power transmission line by the cable wheel assembly.

[0050] Specifically, the cable routing wheel assembly includes a wheel axle and cable routing wheels 15. The wheel axle is rotatably mounted on the bottom end of the outer housing 1 via a bearing. Two cable routing wheels 15 are provided on the wheel axle, with the cable routing wheels 15 close to the inner wall of the outer housing 1.

[0051] One end of the wheel axle is connected to the connecting shaft, and when the de-icing mechanism moves, it simultaneously provides power to the second gear 13 through the connecting shaft.

[0052] Specifically, the hot air baking machine model 4 is WKH-1-A.

[0053] The de-icing device also includes a storage battery 3, which is located on the top of the outer casing 1 and on both sides of the hot air oven 4. The hot air oven 4 is electrically connected to the storage battery 3 to provide power to the hot air oven 4.

[0054] The de-icing device also includes a wireless transceiver controller 5, which is mounted on the outer casing 1 and is wirelessly connected to the remote control of the operating terminal.

[0055] Specifically, the wireless transceiver controller model 5 is DH-W4F1D2SX3000.

[0056] In another embodiment, the de-icing device further includes at least two drive units 6, the output shaft of which is connected to the cable guide assembly.

[0057] The outer wall of the outer casing 1 is provided with a support plate 7, and the drive unit 6 is provided on the support plate 7. Its output shaft is connected to the other end of the wheel axle of the cable guide assembly, and is used to drive the cable guide assembly and the transmission assembly to move.

[0058] Specifically, in this embodiment, the drive unit 6 is a geared motor, model CWS400. The drive unit 6 is connected to the battery 3, which provides power to the drive unit 6.

[0059] The drive unit 6 and the hot air oven 4 are electrically connected to the wireless transceiver controller 5. The drive unit 6 and the hot air oven 4 are started or stopped by sending commands through the remote control via the wireless transceiver controller 5.

[0060] In another embodiment, the de-icing device further includes a limiting frame 2, with a first scraper 8 at one end and a second scraper at the other end of the outer shell 1. The outer shell 1 is inserted into the limiting frame 2 so that the first scraper 8 and the second scraper engage to form an annular scraper.

[0061] The limiting frame 2 is a composite functional component of the de-icing device that enables line guidance and pre-cleaning of ice. The first scraper 8 at its end cooperates with the second scraper at the end of the outer shell 1 to form a circular scraper by inserting the limiting frame 2 into the outer shell 1. The scraper at the front end of the de-icing device is used to process the floating ice broken by the striking mechanism, and the scraper at the rear end of the de-icing device is used to scrape off the ice layer baked by the hot air baking machine 4.

[0062] In another embodiment, the de-icing device further includes a limiting component, wherein a slot 21 is provided at the bottom end of the outer shell 1 and an insert block 18 is provided at the top end of the limiting frame 2; or an insert block 18 is provided at the bottom end of the outer shell 1 and a slot 21 is provided at the top end of the limiting frame 2; and an insertion port 19 is provided on the insert block 18.

[0063] The outer shell 1 or the limiting frame 2 has a limiting component on its side wall. The insert block 18 is inserted into the slot 21 so that the limiting component is inserted into the socket 19 and the outer shell 1 is placed on the limiting frame 2.

[0064] The outer casing 1 has a slot 21 at its bottom end and a plug 18 at its top end; or the outer casing 1 has a plug 18 at its bottom end and the limit frame 2 has a slot 21 at its top end. In other words, if the outer casing 1 has a slot 21 at its bottom end, then the limit frame 2 has a plug 18 at its top end; if the outer casing 1 has a plug 18 at its bottom end, then the limit frame 2 has a slot 21 at its top end, so as to achieve the insertion connection between the two.

[0065] The outer casing 1 or the limiting frame 2 has a limiting component on its side wall. That is, the limiting component is usually set on the outer casing 1 or the limiting frame 2 with the slot 21. The limiting component is inserted into the socket 19 and the outer casing 1 is set on the limiting frame 2 to realize the detachable connection between the outer casing 1 and the limiting frame 2. That is, the outer casing 1 of the de-icing device is placed above the power transmission line through the cable wheel 15 so that the cable wheel 15 is stuck on the power transmission line. Then the limiting frame 2 is inserted into the outer casing 1 from the bottom to fasten the annular scraper to the power transmission line.

[0066] Specifically, in this embodiment, the cross-sectional shape of both the slot 21 and the plug 18 is rectangular. In other embodiments, the cross-sectional shape of the slot 21 and the plug 18 can be adjusted according to the specific working conditions.

[0067] In another embodiment, the limiting component includes a housing 14, a guide rod 24, a limiting block 25, and an elastic element 23. The housing 14 is disposed on the outer wall of the slot 21. The side wall of the slot 21 is provided with a sliding hole. The limiting block 25 is slidably installed in the sliding hole. One end of the limiting block 25 located inside the slot 21 is engaged with the insertion port 19. The other end of the limiting block 25 located inside the housing 14 is connected to the guide rod 24. The guide rod 24 is disposed on the housing 14 and extends at least partially to the outside of the housing 14. The elastic element 23 is sleeved on the guide rod 24 and is located inside the housing 14. One end of the elastic element 23 is fixed to the end face of the limiting block 25, and the other end is fixed to the housing 14.

[0068] The housing 14 is a rectangular shell with a cavity. Its open end is welded to the outer wall of the slot 21, and its closed end has a circular hole for the guide rod 24 to pass through. The side wall of the slot 21 has a sliding hole for installing the limiting block 25. The size of the sliding hole is slightly larger than the size of the limiting block 25 to ensure that the limiting block 25 can be smoothly inserted into the socket 19. The guide rod 24 is a round rod, one end of which is connected to the limiting block 25, and the other end passes through the circular hole on the housing 14. Pulling the guide rod 24 separates the limiting block 25 from the socket 19, at which point the limiting bracket 2 can be removed from the outer shell 1. The elastic element 23 is sleeved on the guide rod 24, and the elastic element 23 is located inside the housing 14. That is, the elastic element 23 is sleeved on the guide rod. 24 is located on the cavity of the housing 14. In this embodiment, the elastic element 23 is a return spring and a compression spring. When the limiting frame 2 is assembled with the outer housing 1, the insert block 18 pushes the limiting block 25 to move towards the housing 14. When the limiting block 25 encounters the insertion port 19, under the action of the elastic element 23, the limiting block 25 is pushed into the insertion port 19 on the insert block 18, so as to realize the stable installation of the limiting frame 2 and the outer housing 1. This allows for quick disassembly and installation of the outer housing 1 and the limiting frame 2, which is more convenient than screw fixing and will not cause stripping.

[0069] Specifically, the contact side between the limiting block 25 and the insert block 18 is provided with an inclined surface. The inclined surface allows the insert block 18 to smoothly push the limiting block 25 toward the housing 14.

[0070] The more specific implementation process is as follows:

[0071] According to the ice thickness setting device parameters of the line to be de-iced: when the ice thickness is 5mm to 10mm, the walking speed is set to 0.5m / min, the hot air temperature is set to 100℃ to 120℃, and the tapping frequency is preset by the proportion of the arc length of the toothless area of ​​the second gear 13 (usually 20 times / min); when the ice thickness is <5mm, the walking speed can be appropriately increased to 0.8m / min to 1m / min, and the hot air temperature can be reduced to 80℃ to 100℃ to reduce energy consumption.

[0072] Line preprocessing:

[0073] Maintenance personnel use insulated operating rods to remove large debris (such as tree branches and plastic bags) from the line surface to prevent debris from entangled in the device and affecting operation; an insulation resistance tester is used to check the insulation layer condition of the transmission and transformation line to be de-iced to ensure that the transmission and transformation line to be de-iced is free from damage and aging, and to avoid the risk of leakage during the operation.

[0074] Equipment hoisting and securing:

[0075] Using an insulated hoisting rope, the de-icing device is hoisted to the area below the power transmission line to be de-iced. Two maintenance personnel work together to insert the device's cable wheel 15 into the power transmission line. The limit frame 2 is then installed on the outer casing 1 until the plug 18 engages with the slot 21.

[0076] The de-icing process involves tapping, scraping, baking, and scraping again.

[0077] The drive unit 6 and the hot air baking machine 4 are started by remotely controlling the wireless transceiver controller 5. At this time, the drive unit 6 drives the wire wheel 15 to roll on the power transmission line, thereby moving the de-icing device on the power transmission line. During the rolling of the wire wheel 15, it drives the second gear 13 to rotate through the connecting shaft 20. The second gear 13 drives the first gear 12 to rotate through intermittent meshing with the first gear 12. The second gear 12 drives the rotating shaft to rotate, which in turn drives the striking part 9 installed on the rotating shaft to rotate in the first direction and causes the reset part 11 to generate torque. When the second gear 13 rotates to the point that it disengages from the first gear 12, the striking part 9 will rotate in the second direction under the action of the reset part 11 to knock and break the ice on the power transmission line. This cycle continues. At the same time, the hot air baking machine 4 blows hot air into the outer shell 1. The hot air will bake and melt the remaining ice on the power transmission line, thereby speeding up the de-icing efficiency of the power transmission line and improving the use effect of the de-icing device.

[0078] If it is found that thick ice (≥10mm) has not been completely broken (large ice layers remain after being struck), the drive unit 6 is controlled by the remote control to reduce the walking speed, extend the time of the striking mechanism on a single section of the line, and at the same time control the hot air baking machine 4 to increase the hot air temperature and enhance the melting ability.

[0079] If the ice layer is thin (<3mm), the drive unit 6 is controlled by the remote control to increase the walking speed, while the hot air baking machine 4 is controlled to reduce the hot air temperature, reduce energy consumption, and avoid overheating of the power transmission and transformation lines.
