Description

Technical Field

[0001] The present invention relates to the technical field of power distribution line safety maintenance, and in particular to a power distribution line double vibration device and a use method thereof. Background Art

[0002] As global climate change intensifies and extreme snow and ice events become more frequent, the problem of line icing is becoming increasingly prominent. Icing of cables in cold regions poses a significant threat to power, communications, and transportation infrastructure. In severe cases, it can lead to power line breakage, communication interruptions, and bridge structural instability. Traditional anti-icing technologies, such as high-frequency vibration, are somewhat effective, but continuous high-frequency vibration consumes significant cumulative energy in cold regions. Furthermore, the required vibration intensity increases nonlinearly with increasing ice thickness. Furthermore, the low vibration amplitude of the entire cable makes it less effective in thick ice. Summary of the Invention

[0003] The technical problem to be solved by the present invention is how to achieve high impact force with lower energy consumption.

[0004] The present invention solves the above technical problems through the following technical means:

[0005] The distribution line double vibration device includes:

[0006] The distribution line double vibration device includes:

[0007] The rotating cover mechanism includes a fixing frame, which is located below the rain cover and is detachably connected to the rain cover. Rotating covers are rotatably mounted on both sides of the fixing frame. A first driving unit is fixed to the fixing frame to drive the rotating cover to open and close.

[0008] Climbing mechanism: includes a belt winding unit, a second drive unit rotatably mounted on a fixed frame, the second drive unit rotates upward under the action of an external force to release the power connection with the belt winding unit, and rotates downward to complete the power connection with the belt winding unit, driving the belt winding unit to rotate, and then winding the synchronous belt; the upper end of the synchronous belt passes through the fixed frame and is fixed to the cable.

[0009] Furthermore, two rotating covers are rotatably installed on both sides of the fixed frame. The rotating covers are fan-shaped and are rotatably installed on the fixed frame at the center. The arc parts of the two rotating covers on opposite sides of the fixed frame are connected by a connecting base. When the four rotating covers on both sides are closed, a space is formed to accommodate the climbing mechanism.

[0010] Furthermore, a first electromagnet is fixed on the fixing frame, and a first metal sheet is installed on the rotating cover. When the rotating cover is opened, the metal sheet is attracted to the first electromagnet.

[0012] Furthermore, a falling stopper is fixed at the bottom of the fixing frame; when the cover rotating mechanism falls, the falling stopper contacts the tape winding unit.

[0013] Furthermore, the second drive unit includes a climbing drive motor, a mounting plate, a climbing drive gear, and a climbing transmission gear; the mounting plate is rotatably connected to the fixed frame; the climbing drive motor, the climbing drive gear, and the climbing transmission gear are all assembled on the mounting plate, and the output end of the climbing drive motor is connected to the climbing drive gear, and the climbing drive gear is meshed with the climbing transmission gear; when the mounting plate is rotated to the transmission position, the climbing transmission gear is power-connected to the winding unit.

[0014] Furthermore, two limit blocks are fixed on the inner side of the rotary cover; when the rotary cover is opened or closed, the two limit blocks respectively cooperate with the end portions of the climbing transmission gear shaft, thereby pushing the mounting plate to rotate.

[0015] Furthermore, a second electromagnet is fixed on the top of the fixed frame, which is used to cooperate with the second metal block fixed at a high position for adsorption; when the climbing mechanism drives the rotating cover mechanism to climb to a high position, the second electromagnet is energized and the adsorption force of the second metal block is used to maintain the high position state of the rotating cover mechanism. When the second electromagnet is energized, the rotating cover mechanism falls to a low position.

[0040] To make the objectives, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

[0041] Example 1

[0042] This embodiment proposes a two-time vibration device for distribution lines, such as Figure 1 As shown, Figure 1Figure (a) is a schematic diagram of the complete anti-icing device structure. Figure (b) hides the outer shell and two rotating covers to reveal its internal structure. It includes a mounting clamp 1, a solar panel 2, a temperature and humidity sensor 3, a control panel 4, a rotating cover mechanism 5, a climbing mechanism 6, a power supply battery 7, and a rain cover 8. The mounting clamp 1 is used to clamp and secure the cable. The rain cover 8 is fixed below the mounting clamp 1. The rotating cover mechanism 5 and the climbing mechanism 6 are formed by a synchronous belt that passes through the rain cover 8 and is fixed to the bottom of the mounting clamp 1. To protect against rain, an outer shell is also fixed to the outside of the rotating cover mechanism, and the solar panel 2 and temperature and humidity sensor 3 are both fixed to the outside of the outer shell. The solar panel 2 and temperature and humidity sensor 3 can be fixed to the outer shell by, but are not limited to, welding, screwing, or snapping. The structure and working principle of each component are described in detail below.

[0043] 1. Design of cover turning mechanism 5

[0044] like Figure 2 As shown, Figure 2 Figure a is a schematic diagram of the complete rotating cover mechanism, while figure b is a schematic diagram of the internal structure with the two rotating covers hidden. The rotating cover mechanism primarily consists of a fixed frame 51, a first electromagnet 52, a metal detection switch 53, a rotating cover drive motor 56, a transmission gear 57, a rotating cover drive gear 58, a rotating cover drive rack 59, and a connecting base 510. The rotating cover drive motor 56, transmission gear 57, rotating cover drive gear 58, and rotating cover drive rack 59 constitute the first drive unit. The fixed frame 51 supports the entire device and has a certain height to meet the installation space and location requirements of other components. The fixed frame 51 is formed by two parallel vertical plates at the front and rear, connected at the top by a horizontal plate. The width between the two vertical plates is sufficient for the width of the flat synchronous belt and smooth passage, and the horizontal plate has a gap for the synchronous belt to pass through. The components mounted on the outer sides of the two vertical plates are identical. The following uses one of the vertical plates as an example to explain the position, assembly relationship, and operating principle of the remaining components.

[0045] Two rotating covers are rotatably mounted on the bottoms of the two vertical plates of the fixed frame 51. All four covers are identical in shape and size, and are fan-shaped. The arc portions of the two opposite covers are connected by a curved connecting base 510, forming a three-dimensional fan-shaped structure with a accommodating cavity. Taking one side as an example, they are designated as the left and right cover plates 54 and 55, respectively. The left and right cover plates 54 and 55 are rotatably mounted on the vertical plates at their centers via a rotating shaft, which also serves as the rotating shaft for the two opposite covers. When the two covers are closed, their adjacent edges abut against each other, forming a larger fan-shaped cover. A rotating cover drive motor 56 is fixed to the fixed frame, with a rotating cover drive gear 58 attached to its output end. A rotating cover drive rack 59 is fixed to the connecting base 510, corresponding to the rotating cover drive gear 58, and meshes with the rotating cover drive gear 58. To reduce the number of drive mechanisms, this embodiment employs transmission gears 57 mounted on the rotating shafts of the two rotating covers on the same side. These two transmission gears 57 mesh with each other. When the rotating cover drive motor 56 rotates one of the rotating covers, the other cover also rotates synchronously under the drive of the transmission wheel, achieving the opening and closing of the entire structure. In this embodiment, the rotating cover drive motor 56 utilizes a dual-axis output, simultaneously delivering power to the opposite rotating cover. The opposite cover then uses the same transmission mechanism to close.

[0046] In this embodiment, a first electromagnet 52 is also fixed to the fixed frame 51, and a first metal sheet 511 extends from the rotating cover. When the rotating cover is opened to the set position, the first metal sheet 511 attracts the first electromagnet 52. The attraction of the first electromagnet reduces the moment generated by gravity on the left and right side panels of the rotating cover during the falling process, thereby reducing the impact on the gear rack 59. In this embodiment, to determine whether the rotating cover has been rotated to the set position, a metal detection switch 53 is also installed on the fixed frame 51. When the first metal sheet 511 reaches the set position, it can turn off the rotating cover drive motor 56 to save energy.

[0047] like Figure 3 As shown, the rotary cover mechanism is rotated to the open state. In the open state, the first electromagnet 52 is attracted to the first metal sheet 511 fixed to the tail of the right side plate 55 of the rotary cover. Figure 4 This diagram shows the rotating cover mechanism at its maximum rotational opening. The cover is hidden in the figure, revealing only the internal structure. To conserve electricity, this embodiment uses a demagnetized electromagnet as the first electromagnet. When the cover is open, the first electromagnet is de-energized. When the cover is closed, it is de-energized. Since the cover's closed time is always greater than its open time, this significantly saves electricity.

[0048] The function realized by the cover turning mechanism is opening and closing function, without intermediate transition state, and the intermediate position does not need to be controlled, so the DC motor is selected to cooperate with the front and rear two groups of metal detection switches 53 to realize the opening and closing position control of the function, which is relatively lower in cost compared with the stepper motor and servo motor, and the control is simpler. The motor is installed at the tail part, the force arm is larger relative to the installation at the rotating shaft part, so that the required motor provides smaller torque, and at the same time, the space is fully utilized to prevent the overall protrusion.

[0049] 2. Structure introduction of the climbing mechanism 6

[0050] The climbing mechanism is shown in Figure 5 , and mainly consists of a climbing driving motor 61, a motor mounting plate 62, a climbing driving gear 63, a climbing transmission gear 64, an adjusting limiting block 65, a winding belt unit 66, a winding belt supporting block 67, and a falling blocking block 68. The climbing driving motor 61, the motor mounting plate 62, the climbing driving gear 63, and the climbing transmission gear 64 constitute a second driving unit. The climbing driving motor 61 is fixedly connected to the motor mounting plate 62, the top of the motor mounting plate 62 is hingedly connected to the fixed frame 51, the climbing driving gear 63 is fixedly connected to the motor output shaft, and the climbing transmission gear 64 is hingedly connected to the motor mounting plate 62 by a bearing to transmit force. The end of the rotating shaft of the climbing transmission gear 64 protrudes, the adjusting limiting block 65 has two blocks, which are fixedly connected to the inner side wall of the right side plate 55 of the cover turning mechanism. With the opening and closing of the cover turning mechanism, the two adjusting limiting blocks 65 drive the rotating of the motor mounting plate 62 by pushing the protruding part of the end of the rotating shaft of the climbing transmission gear 64, and then make the climbing transmission gear 64 mesh with or away from the winding shaft gear 661 of the winding belt unit 66, to prevent the gear from being worn by the contact of the gear during the falling process of the device. The winding belt unit 66 is mainly used to realize the winding of the synchronous belt 667 to realize the climbing of the overall device, and the winding belt supporting block 67 is fixedly connected to the left and right side plates of the cover turning mechanism. When the cover turning mechanism is closed, the winding belt supporting block 67 supports the end of the rotating shaft of the winding belt unit 66 to realize the winding rotation. Figure 6 、 Figure 7 The falling blocking block 68 is shown in

[0051] The inside of the winding belt unit 66 is shown in Figure 8 Figure 8 ​The figure on the right is a schematic diagram of the structure in which a rotating shaft gear 661 is omitted; it mainly consists of a reel gear 661, a reel bearing 662, a reel support shaft 663, a reel retaining ring 664, a first cassette shaft 665, a second cassette shaft 666, and a synchronous belt 667. The reel gear 661 is fixedly connected to the reel retaining ring 664, the reel support shaft 663 is fixedly connected to the reel retaining ring 664, the reel bearing 662 is hinged on the reel support shaft 663, the first cassette shaft 665 and the second cassette shaft 666 are fixedly connected. On the front and rear sets of reel retaining rings 664, a synchronous belt 667 is stuck inside. The combined travel teeth of the first cassette shaft 665 and the second cassette shaft 666 are engaged with the teeth of the synchronous belt 667 to increase the stability of the device. When the rotating cover mechanism is closed, the tape support block 67 supports the front and rear sets of reel bearings 662. The climbing drive motor 61 transmits power through the climbing drive gear 63 and the climbing transmission gear 64 to realize the rotation of the tape mechanism, and then realizes the winding of the synchronous belt 667 to realize the climbing of the device.

[0052] The schematic diagram of the position of the cover mechanism opening, closing and climbing driving gear 63 is as follows: Figure 9 、 Figure 10 As shown, Figure 10 The positional relationship between the climbing transmission gear 64 and the tape winding unit 66 when the rotary cover is in the closed and open states in Example 1 of the present invention; Figure 10 The upper and lower figures on the left and right correspond to each other. When the rotating cover mechanism is in the closed state, the tape support blocks 67 fixed to the left and right rotating covers provide support for the reel bearing 662 in the tape unit 66. The adjustment limit block 65 limits the axis of the mounting bearing of the climbing transmission gear 64, preventing the reel gear 661 from disengaging when the climbing transmission gear 64 is engaged. When the rotating cover mechanism is in the open state, the adjustment limit block 65 fixed at the bottom causes the motor mounting plate 62 to rotate. At this time, there is a certain distance between the reel gear 661 and the climbing transmission gear 64, preventing the tooth surfaces from not contacting each other when the tape unit 66 contacts the falling block 68 during the entire device downward movement.

[0053] 3. Auxiliary parts structure design

[0054] like Figure 12As shown, to ensure that the rotating cover mechanism and its external housing remain elevated, the present application further includes a second electromagnet 20 affixed to the top of the mounting bracket 51 and a second metal sheet 21 affixed to the bottom of the rain cover. During the ascent process, if the metal detection switch 83 detects contact with the plate, the climbing mechanism stops ascending. At this point, the second electromagnet affixed to the mounting bracket is adsorbed onto the second metal sheet. When de-icing is not required, the second electromagnet is in an adsorbed state, used to suspend the entire device. To conserve electricity, this embodiment utilizes a powered demagnetized electromagnet. When the rotating cover mechanism needs to be suspended, the second electromagnet is de-energized. When the rotating cover mechanism needs to be lowered, the second electromagnet is energized. Since the suspended time of the rotating cover mechanism is always greater than the lowering time, this significantly saves electricity.

[0055] During the descent, the distribution line double vibration device slides rapidly along the timing belt 667, creating friction between the device and the device itself. Deep groove ball bearings 681 are hinged around the bottom drop block 68 to reduce friction. Bearings are also distributed around the upper portion and on both sides of the fixed frame 51. The transmission teeth on the toothed ends of the timing belt 667 have been removed to prevent scratching during the device's descent.

[0056] Compared to a rope, using a synchronous belt 667 makes it easier to control the direction of descent and ascent. Synchronous belt 667 is a flat, long strip that does not rotate around it. This ensures that during the descent, the lowering block 68 always contacts the front of the belt unit 66, increasing the contact surface and reducing impact on the device. During the ascent, the synchronous belt 667 is limited by a rolling bearing, so that the direction of the electromagnet 82 always corresponds to the contact plate, thereby controlling the overall direction of the device, ensuring that the solar photovoltaic panel always faces the light side.

[0057] The whole device is as follows Figure 13 As shown, the rain shield 8 is fixed to the cable to increase the waterproof effect of the device body. The device body adopts two integral left and right shells to reduce the splicing seams. At the same time, sealant is attached to the splicing seams. Sealant is also attached to the seam surfaces of the left and right side panels of the rotating cover of the lower rotating cover mechanism. In the closed state, the left and right side panels are clamped to each other. Due to the presence of sealant, a waterproof effect is achieved. A rain shield extending outward is added above the rotating cover mechanism to increase the waterproof effect.

[0058] 4. Install the structure of wire clamp 1

[0059] like Figure 14As shown, the cable clamp 1 is primarily composed of a guide post 11, an external hexagonal bolt 12, a clamping block 13, a cable clamp body 10, and a mounting plate 14. The cable clamp body 10 includes a hook 15 at the top and a mounting plate 14 extending from the hook 15. Two sets of guide posts 11 are fixed to the rear end of the clamping block 13. The guide posts 11 pass through the mounting plate 14 and slide in engagement with the mounting plate 14. The clamping block 13 is located within the clamping cavity of the hook 15. The mounting plate 14 also has a threaded hole into which the external hexagonal bolt 12 is threadedly connected. The top of the external hexagonal bolt 12 passes through the mounting plate 14 and is rotationally secured to the clamping block 13 (rotational securing methods include, but are not limited to, bearings and rotating clamping). The clamping block 13 is moved forward by tightening the external hexagonal bolt 12. The two guide posts 11 are primarily intended to prevent the clamping block 13 from rotating with the hexagonal bolt 12 during tightening. The position of the clamping block 13 adjusts the diameter of the clamping cavity of the hook 15, thereby accommodating cables of varying diameters. The mounting splint 14 has a lower tooth profile that cooperates with the teeth of the synchronous belt, and the bolts penetrate the synchronous belt to achieve a better fixing effect.

[0060] The composition and working principle of the two-time vibration device for distribution lines are as follows:

[0061] The distribution line double vibration device primarily uses a mounting clamp to attach the entire device to the required cable. The mounting clamp primarily uses two mutually clamping clamps to clamp the cable, and the clamps can be adjusted to accommodate different wire diameters. Power replenishment primarily relies on the solar photovoltaic panels attached to the surface. Adjusting the mounting clamp's orientation ensures the panels are always facing the sun. Temperature and humidity sensors primarily collect ambient information, and a control panel controls overall operation.

[0062] like Figure 15 As shown, when the detected temperature and humidity are below a preset value, the first drive unit is activated, and the rotating cover mechanism opens. When the rotating cover opens, the two adjustable limit blocks 65 drive the second drive unit away from the tape unit, causing the tape unit to fall under its own weight and complete the first vibration. At this time, the second electromagnet 20 is released, relying on the impact force generated by the gravity of the entire device to achieve a second vibration of the cable. The first vibration is relatively weak, but can be effective in the early stages of ice formation. De-icing is mainly achieved through the second vibration. Compared to the continuous high-frequency vibration of vibrators on the market, the vibration amplitude achieved by gravity is larger. After completing the vibration of the cable, the first drive unit is activated to close the rotating cover mechanism. During the rotating cover closing process, the second drive unit is driven to rotate by the two adjustable limit blocks 65, establishing a power connection with the tape unit. The second drive unit is then activated, and the tape unit begins to rewind the synchronous belt. The climbing mechanism achieves the climbing of the entire device. When the metal detection switch on the top detects metal, the climbing mechanism stops, realizing the reset of the device. Repeating this process can achieve regular or irregular vibration of the wire.

[0063] This example combines theoretical modeling, numerical calculations, and experimental verification, and develops temperature and humidity detection. When the temperature falls below a preset value, the wire is automatically vibrated to achieve efficient and low-energy deicing. This research finding provides a new technical solution for cable deicing in cold regions and has important guiding significance for the engineering application of vibration deicing technology.

[0064] Example 2

[0065] This embodiment provides a wire clamp installation tool for hooking the device of embodiment 1 onto a cable.

[0066] like Figure 16 As shown, the wire clamp installation tool is mainly composed of an electric push rod 91, a fixed shell 92, a mounting base 93, a plum blossom connector 94, a connecting shaft 95, a guide fork 96, a fixed side plate 97, a rotating sleeve 99, and a support plate 910. The guide fork 96, the fixed side plate 97, and the rotating sleeve 99 are all located on the same side of the fixed shell. The mounting base 93 supports the tool as a whole, the plum blossom connection seat 94 is fixedly connected to the bottom of the mounting base 93, the fixed shell 92 is fixedly connected to the top of the mounting base 93, the output end of the electric push rod 91 is hinged to the connecting shaft 95, and the fixed end is hinged to the top of the fixed shell 92, the left and right fixed side plates 97 are fixedly connected to the mounting base 93, and are used to support the installation of the wire clamp 1, the left and right guide forks 96 have two connection points, and the two connection points are arranged in a Y shape. The first connection point at the bottom is hinged to the outer wall of the fixed side plate 97, and the second connection point at the top is fixedly connected to the connecting shaft 95. The guide fork 96 is rotated up and down by the extension and contraction of the electric push rod 91. The drive motor 98 is located inside the fixed shell 92, and its output end extends out of the fixed shell 92. The output end flange surface is fixedly connected to a rotating sleeve 99, and the rotating sleeve 99 is located between the two fixed side plates 97. The support plate 910 is fixedly connected to the mounting base 93 to support the bottom of the installation wire clamp. A baffle 961 is fixed on the inner side of the guide fork 96, and an open limiting groove 971 is opened on the top of the fixed side plate 97, which is used to limit the two bolts on both sides of the installation wire clamp 1. When the guide fork rotates downward, the baffle 961 blocks the notch of the limiting groove 971 to prevent the installation wire clamp from falling off. Figure 17 From left to right, the following diagrams show the state changes when the installation clamp is placed into the installation tool, the guide fork rotates downward, and the cable is clamped into the installation clamp.

[0067] The operation steps of the distribution line anti-icing device installation tool are as follows: Figure 18As shown, first fix the installation tool to the insulating operating rod, and install the installation wire clamp fixed with the anti-icing device into the installation tool, wherein the two ends of the installation wire clamp are fixed with bolts. During installation, the bolts on both sides are inserted into the limiting grooves 971 of the fixed side plates 97 on both sides, and the external hexagonal bolts 12 on the back of the installation wire clamp are inserted into the rotating sleeve 99. The electric push rod 91 of the installation tool is controlled to extend, and the guide fork 96 rotates to drive the baffle 961 to block the exit of the limiting groove 971 of the fixed side plate 97 to prevent the wire clamp from falling off. The cable clamp is then positioned vertically downwards, with the center of gravity of the clamp centered at the center of the cable. This prevents the clamp from rotating around the cable during impact and damaging its insulation. The electric push rod 91 is then retracted, opening the guide forks 96. The installation tool is then removed, completing the installation.

[0068] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit the same. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the various embodiments of the present invention.
