[0034] Example 1

[0035] like Figures 1 to 4 As shown, the deicing device for the split conductor 6 provided in the embodiment of the present invention includes a support component, an elastic impact component, a power supply module, a monitoring module 7 , a communication module and a control module 3 .

[0036] Among them, the support assembly is installed between any two branches of the split conductor, the elastic impact assembly is fixed on the support assembly, the impact direction of the elastic impact assembly is set towards any branch line, the monitoring module is fixed on any branch line, the monitoring module is used to monitor the icing condition of the branch line, the control module is fixed on the support assembly and is electrically connected to the monitoring module and the elastic impact assembly respectively. When the monitoring module detects that the branch line begins to be covered with ice, the elastic impact assembly is adjusted to an elastic energy storage state; when the monitoring module detects that the icing condition on the branch line exceeds a preset threshold, the elastic impact assembly in the elastic energy storage state is released to impact the split conductor for de-icing.

[0037] Specifically, if Figure 1 As shown, the support assembly in this embodiment of the present invention includes a support beam 11, two support brackets 12 fixed to the support beam 11, and movable connection ends 111 and fixed connection ends 112 at both ends of the support beam 11. The movable connection ends 111 and fixed connection ends 112 are both annular claws. The movable connection ends 111 and fixed connection ends 112 are respectively connected to the two branches of the split conductor 6. The support beam is a telescopic rod structure, and a slide rail (not shown) is provided within the support beam 11 to secure the movable connection ends 111 so that the movable connection ends 111 can move with the slide rail.

[0038] When the installation is completed, the movable connection end 111 and the fixed connection end 112 on the support beam 11 are fixedly connected to the first branch 61 and the second branch 62 located in the horizontal direction in the split conductor 6 respectively, and the two support brackets 12 are suspended and fixed under the support beam 11, and the power supply module, communication module, control module 3 and elastic impact assembly are all fixed on the two support brackets 12.

[0039] Continue reading Figures 1 to 3 In the embodiment of the present invention, the elastic impact assembly includes an impact head 23, a first cylinder 21, a second cylinder 22, a coil spring 26, a connecting rod 25 and a first motor 24. The impact head 23 and the first branch line 61 are arranged horizontally relative to each other, and the first cylinder 21 is horizontally fixed on two support brackets 12; the left end of the second cylinder 22 is axially slidably sleeved with the right end of the first cylinder 21, and the right end of the second cylinder 22 is fixedly mounted on the impact head 23; the coil spring 26 is located in the first cylinder 21 and the right end of the coil spring 26 is fixed to the right bottom of the first cylinder 21, and the left end of the coil spring 26 is fixed to the impact head 23; the connecting rod 25 is located in the coil spring 26 and is located on the central axis of the first cylinder 21. A locking assembly is provided on the left end of the connecting rod 25, and the locking assembly is tightly locked with the impact head 23. The right end of the connecting rod 25 axially passes through the first cylinder 21 and the right end of the connecting rod 25 is located outside the second cylinder 22.

[0040] When the impact head 23 hits the first branch line 61 in the split conductor 6 horizontally, the displacement direction of the impact head 23 hitting the branch line is parallel to the support beam 11, so that after being hit, the first branch line 61 drives the movable connection end 111 to swing horizontally left and right on the support beam 11.

[0041] Continue reading Figures 1 to 3 A worm gear (not shown in the figure) is installed on the output shaft of the first motor 24, and a bar tooth (not shown in the figure) is provided on the connecting rod 25 located outside the second cylinder 22. The first motor 24 drives the worm gear and the bar teeth on the connecting rod 25 to drive the connecting rod 25 to move left and right along the axial direction of the first cylinder 21 in a worm gear matching transmission manner.

[0042] like Figure 3 and Figure 4 As shown, in this embodiment of the present invention, a first hook 233 is provided on the impact head 23. The locking assembly includes a second hook 28 disposed on the connecting rod 25 and a second motor. The second hook 28 and the second motor engage with each other via gears to lock or unlock the second hook 28 with the first hook 233. Specifically, a first gear 251 is mounted on the output shaft of the second motor, and a second gear 281 is mounted on the second hook 28. The second motor drives the first gear 251 to engage with the second gear 281 to rotate the second hook 28 and engage or release the second hook 28 with the first hook 233 in the axial direction of the first cylinder 21.

[0043] It should be noted that the first motor 24 and the second motor are electrically connected to the control module 3 and the power supply module respectively.

[0044] like Figure 3 As shown, the elastic impact assembly in the embodiment of the present invention also includes a third cylinder 27, which is located in the first cylinder 21 and is coaxially arranged with the first cylinder 21, and the coil spring 26 is sleeved on the outside of the third cylinder 27, and the connecting rod 25 and the locking assembly are both located in the third cylinder 27, thereby avoiding interference between the coil spring 26 and the locking assembly or the connecting rod 25 after being compressed and deformed, and the third cylinder 27 plays a guiding role in the compression and release of the coil spring 26, thereby improving the safety and stability of the elastic impact assembly in the working state.

[0045] like Figure 3 and Figure 4 As shown, the impact head 23 in this embodiment of the present invention includes a collision plate 231 and a circular fixing plate 232. The extended upper area of ​​the collision plate 231 is used to impact the branch line, and the lower area of ​​the collision plate 231 is connected and fixed to the fixing plate 232. The first hook 233 is mounted on the fixing plate 232. The edge of the fixing plate 232 is fixedly connected to the left end of the second cylinder 22, and the inner side of the fixing plate 232 abuts or is fixed to the left end of the coil spring 26.

[0046] When installed, the collision plate 231 is located below the support beam 11, and a notch 2311 is provided on the upper portion of the collision plate 231 to avoid the support beam 11. In other words, when the collision plate 231 strikes the branch line at the same level as the support beam 11, the collision plate 231 and the support beam 11 are prevented from interfering with each other.

[0047] like Figure 1 and Figure 2 As shown, the power supply module in the embodiment of the present invention includes an energy storage battery 4 and an induction coil 5 electrically connected to the energy storage battery 4 . The induction coil 5 is installed on the second branch line 62 to charge the energy storage battery 4 .

[0048] like Figure 2 As shown, the monitoring module 7 in the embodiment of the present invention is fixed on the second branch line 62 for monitoring the ice condition of the split conductor 6. The monitoring module 7 is wirelessly connected to the communication module 7. The monitoring module 7 includes a video collector.

[0049] It should be noted that, in actual applications, those skilled in the art may choose to use a tension sensor to replace the video collector to monitor the stress state of the conductor to feedback the icing condition, or they may also use a combination of a video collector and a tension sensor to monitor the icing condition of the conductor. Such selection, adjustment and change of the monitoring module 7 does not deviate from the principle and scope of the present invention and should be included in the protection scope of the present invention.

[0050] In addition, the monitoring module 7 adopts the inductive power supply method in the prior art so that the monitoring module 7 is set on the other wires in the split wire 6 to obtain power.

[0051] like Figure 1 and Figure 2 As shown, the de-icing device further includes a displacement feedback module 8 electrically connected to the control module 3. Displacement feedback module 8 is fixed to the support beam 11 and is configured to measure the swing displacement state of the first conductive wire. Specifically, displacement feedback module 8 includes a distance sensor mounted on the support beam 11 and aligned with the movable connection end 111 to measure the distance between the movable connection end 111 and the distance sensor in real time as the movable connection end 111 swings left and right on the support beam 11.

[0052] After the impact de-icing, the impact head 23 strikes the first branch line 61 again according to the left-right swing displacement of the movable connection end 111 on the support beam 11, thereby quickly suppressing the de-icing vibration of the first branch line 61.

[0053] In addition, if Figure 1 and Figure 2As shown, the deicing device in this embodiment of the present invention further includes a housing 13, which is fixed to the support bracket 12. The housing 13 shields the elastic impact assembly, power supply module, communication module and control module 3 on the support bracket 12 to prevent rain and snow from intruding.

[0054] The working process of the deicing device according to the embodiment of the present invention is as follows:

[0055] When the de-icing device is performing energy storage operation, the control module 3 controls the first motor 24 to drive the connecting rod 25 to move axially to the first hook 233. The control module 3 then controls the second motor to drive the second hook 28 to cooperate with the first hook 233 to lock the impact head 23. After locking the impact head 23, the control module 3 controls the first motor 24 to drive the connecting rod 25 to pull the impact head 23 axially, thereby compressing the coil spring 26, causing the impact head 23 to reach the preset energy storage position.

[0056] It should be noted that the control module 3 can determine the preset energy storage position to control the impact force of the impact head 23 based on parameters such as the ice area level, ice thickness, ice type, line span, line height difference, conductor model and swing information of the transmission line.

[0057] When the de-icing device performs a release operation: when the ice thickness on the second branch line 62 reaches a set threshold, the control module 3 controls the second motor to drive the second hook 28 and the first hook 233 to decouple and unlock each other, so that the impact head 23 is ejected horizontally by the coil spring 26 and then hits the first branch line 61 for vibration de-icing.

[0058] The inventors' research has found that longitudinal oscillation of transmission lines typically causes tension changes in the lines. These changes can exceed the designed load-bearing capacity of the transmission lines, leading to excessive stretching and an increased risk of breakage. In contrast, transmission lines have greater structural strength in the horizontal direction, making them more resilient to lateral impact and oscillation.

[0059] Therefore, compared with the existing de-icing device with longitudinal vibration mode, when the de-icing device of the present invention is in the stationary working state, the de-icing device is arranged in the horizontal direction so that the split conductor hit by the released impact head 23 produces horizontal vibration de-icing, avoiding the violent swing of the split conductor in the longitudinal direction, thereby reducing the mechanical damage effect of the longitudinal impact vibration on the split conductor.

[0060] In addition, the impact head 23 released in the horizontal direction by the deicing device of the present invention can also suppress the violent swing of the split conductor in the horizontal direction, thereby ensuring the safety and stability of the split conductor.

[0061] The specific operation suppression and vibration reduction process is as follows: the above-mentioned energy storage operation steps are performed on the de-icing device again. When the split conductor 6 is in a swinging state after vibration de-icing, that is, when the displacement feedback module 8 monitors that the first branch 61 swings toward the impact head 23 and moves to the vibration center, the control module 3 controls the second motor to drive the second hook 28 and the first hook 233 to decouple and unlock each other, so that the impact head 23 is bounced out in the horizontal direction by the coil spring 26 and then hits the first branch 61 to suppress the swing of the first branch 61.

[0062] It should be noted that, since the fixed connection end 112 fixed on the second branch line 62 is subjected to a reverse force, the second branch line 62 is simultaneously subjected to an impact de-icing or swing suppression effect.

[0063] In addition, the split conductor also includes a third branch line, and the deicing device also includes a transmission connecting rod (not shown in the figure), one end of the transmission connecting rod is connected to the third branch line, and the other end of the transmission connecting rod is connected to the first branch line 61.

[0064] Specifically, when the de-icing device is installed on a split conductor 6 such as a three-split conductor, a four-split conductor, a six-split conductor, an eight-split conductor, or a ten-split conductor, after the support beam 11 of the de-icing device is set horizontally, any other branch line is connected to the first branch line 61 through a transmission connecting rod, and then the vibration on the first branch line 61 is transmitted to other branches through the transmission connecting rod for vibration de-icing.

[0065] Example 2

[0066] Based on the same inventive concept, the present invention further provides a control method for the deicing device in Example 1, which mainly includes:

[0067] S1. Obtaining the ice thickness of the split conductor 6 based on the monitoring module 7 of the deicing device;

[0068] S2. When the ice thickness of the split conductor 6 is within a set threshold range, the control module 3 adjusts and controls the elastic impact assembly to the elastic energy storage working position;

[0069] S3. When the ice thickness exceeds a threshold range, the control module 3 adjusts and controls the elastic impact component to release elastic energy at the working position.

[0070] It is understandable that the control method of the deicing device can automatically start controlling and adjusting the working state of the elastic impact component and perform automatic deicing according to the actual ice thickness on the split conductor 6 without manual monitoring.

[0071] It should be noted that when the ice thickness is less than the threshold, control module 3 controls first motor 24 to be inoperative. In other words, the ice thickness on split conductor 6 does not meet the conditions for triggering the de-icing device. Therefore, there is no need to adjust the elastic impact assembly for energy storage, allowing coil spring 26 to remain in a naturally extended state to maintain good elastic properties.

[0072] Specifically, in step S1 , the ice thickness is fed back by the video collector in the monitoring module 7 installed on the second branch line 62 .

[0073] The threshold range of ice thickness is set to trigger the de-icing device to automatically de-ice. The threshold range is set to 4mm-6mm.

[0074] like Figure 3 As shown, the coil spring 26 in the elastic impact assembly remains in a non-compressed state, and the first hook 233 on the impact head 23 and the second hook 28 in the elastic impact assembly remain in a separated state.

[0075] For example, when the ice coating thickness of the split conductor 6 is 5 mm, which is within the threshold range of 4 mm to 6 mm, the control module 3 adjusts and controls the elastic impact assembly to the elastic energy storage working position in advance.

[0076] The step S2 specifically includes:

[0077] S21, the control module 3 adjusts and utilizes the first motor 24 of the elastic impact assembly to drive and control the connecting rod 25 of the elastic impact assembly to move axially so that the locking assembly of the elastic impact assembly approaches the impact head 23 of the elastic impact assembly;

[0078] That is, the first motor 24 is used to drive the connecting rod 25 to move axially so that the second hook 28 of the locking assembly of the elastic impact assembly is close to the first hook 233 of the impact head;

[0079] S22, the control module 3 controls the locking assembly to lock the impact head 23;

[0080] Specifically, the control module 3 adjusts and utilizes the second motor driving the locking assembly to control the second hook 28 on the locking assembly to lock with the first hook 233 on the impact head 23 through gear meshing transmission.

[0081] That is, the second motor drives the first gear 251 and the second gear 281 to cooperate and transmit so that the second hook 28 and the first hook 233 on the locking assembly are locked to each other;

[0082] S23 , the control module 3 adjusts and utilizes the first motor 24 to drive the control connecting rod 25 to pull the impact head 23 to compress the coil spring 26 of the elastic impact assembly to a preset position.

[0083] That is, after the impact head 23 is locked, the first motor 24 is used to drive the connecting rod 25 to axially pull the impact head 23 and thereby compress the coil spring 26 , so that the impact head 23 reaches a preset energy-storing working position.

[0084] It should be noted that, according to actual applications, those skilled in the art can set the specific axial working position of the impact head 23 according to the threshold range to compress the coil spring 26 and thereby adjust the energy storage size of the elastic impact assembly.

[0085] For example, when the ice coating thickness of the split conductor 6 is 6.1 mm, the de-icing device is triggered to release elastic energy for vibration de-icing.

[0086] See Figure 3 The specific operation steps of step S3 are as follows: the control module 3 controls and adjusts the second motor to drive the first gear 251 and the second gear 281 to cooperate in transmission so that the second hook 28 and the first hook 233 are decoupled and unlocked from each other, so that the impact head 23 is bounced out horizontally by the coil spring 26 and then hits the first branch line 61 for vibration de-icing.

[0087] In addition, the control method further comprises:

[0088] S4, obtaining the swing information of the split conductor 6 after impact deicing based on the displacement feedback module 8 of the deicing device;

[0089] S5. Determine whether to adjust the elastic impact component to suppress the swing of the split conductor 6 according to the swing information.

[0090] It can be understood that after impact vibration deicing, the control method of this deicing device can also suppress the vibration of the split conductor 6 according to the swinging state of the split conductor 6 after deicing, so as to achieve the purpose of quickly balancing and stabilizing the split conductor 6 and ensure the safety and stability of the split conductor 6.

[0091] The specific steps of the control method are as follows:

[0092] In step S4, the swing information is fed back to the first branch line 61 by determining the passive extension and contraction state of the movable connection end 111 on the support beam 11 through the displacement feedback module 8 installed on the support beam 11;

[0093] In step S5, the swing information includes the horizontal displacement of the branch of the impacted split conductor 6. That is, the horizontal displacement is determined by the difference between the maximum and minimum distances between the movable connection terminal 111 and the ranging sensor feedback. The threshold of the horizontal displacement is set to 5 cm. The control method specifically includes:

[0094] S51, when the horizontal displacement is greater than the threshold, the elastic impact assembly is adjusted to the energy storage position according to the horizontal displacement, and when the branch line moves to the horizontal displacement center and swings toward the impact head 23, the impact head 23 is released.

[0095] For example, when the horizontal displacement is 7 cm, that is, the horizontal displacement of the first branch line 61 of 7 cm is greater than the threshold value of 5 cm, indicating that the first branch line 61 is swinging violently, the elastic impact assembly is adjusted to the energy storage gear according to the horizontal displacement, and when the first branch line 61 moves to the center of the horizontal displacement and swings toward the impact head 23, the impact head 23 is released to impact the swinging first branch line 61. In other words, an impulse opposite to the movement of the first branch line 61 is applied to quickly suppress the swing of the first branch line 61, reduce the violent oscillation of the split conductor 6 after the vibration impact deicing, and ensure the safety and stability of the split conductor 6. It should be noted that the process of adjusting the elastic impact assembly to the energy storage gear and releasing the impact head 23 is the same as the above-mentioned steps S2 and S3, so it will not be repeated.

[0096] S52: When the horizontal displacement is not greater than the threshold value, the elastic impact component is not adjusted;

[0097] For example, if the horizontal displacement of the first branch line 61 after deicing is 3 cm, which is less than the threshold of 5 cm, the elastic impact assembly is not adjusted. In other words, the swing distance of the first branch line 61 does not affect the safety of the split conductor 6 , and the first branch line 61 relies on its free swing in the air to dissipate vibration energy and reach a static equilibrium state.

[0098] It should be noted that the above threshold range and threshold value are only for explaining the working principle of the control method, and are not specific limitations on the invention.

[0099] The above are merely embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention are included in the scope of the claims of the present invention.
