[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 supporting component, an elastic impact component, a power supply module, a monitoring module 7 , a communication module and a control module 3 .

[0037] Specifically, Figure 1 As shown, the support assembly in the embodiment of the present invention includes a support beam 11, two support brackets 12 fixed on the support beam 11, and a movable connection end 111 and a fixed connection end 112 located at both ends of the support beam 11, and the movable connection end 111 and the fixed connection end 112 are both claws of annular structures. The movable connection end 111 and the fixed connection end 112 are respectively connected to the two branches of the split conductor 6. Among them, the support beam is a telescopic rod structure, and a slide rail (not shown in the figure) for fixing the movable connection end 111 is provided in the support beam 11 so that the movable connection end 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 line 61 and the second branch line 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 opposite to each other in the horizontal direction, 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 installed with 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, and 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, and 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 impacts the first branch line 61 in the split conductor 6 in the horizontal direction, the displacement direction of the impact head 23 hitting the branch line is parallel to the support beam 11, so that after being impacted, the first branch line 61 drives the movable connection end 111 to extend and 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 the embodiment of the present invention, a first hook 233 is provided on the impact head 23, and the locking assembly includes a second hook 28 and a second motor provided on the connecting rod 25. The second hook 28 and the second motor are engaged and transmitted through gears to lock or unlock the second hook 28 and the first hook 233. Specifically, a first gear 251 is installed on the output shaft of the second motor, and a second gear 281 is installed on the second hook 28. The second motor drives the first gear 251 to cooperate with the second gear 281 to rotate the second hook 28 and make the second hook 28 engage or release the engagement 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, the third cylinder 27 is located in the first cylinder 21 and is coaxially arranged with the first cylinder 21, the coil spring 26 is sleeved on the outside of the third cylinder 27, the connecting rod 25 and the locking assembly are both located in the third cylinder 27, so as to avoid the coil spring 26 from interfering with 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 the embodiment of the present invention includes a collision plate 231 and a circular fixing plate 232. The upper area of ​​the collision plate 231 is used to impact the branch line, the lower area of ​​the collision plate 231 is connected and fixed to the fixing plate 232, the first hook 233 is installed on the fixing plate 232, the edge side 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 is abutted or fixed to the left end of the coil spring 26.

[0046] In the installed state, the collision plate 231 is located below the support beam 11, and the upper area of ​​the collision plate 231 is provided with a notch 2311 to avoid the support beam 11. That is, when the collision plate 231 hits the branch line at the horizontal position where the support beam 11 is located, the collision plate 231 and the support beam 11 are prevented from interfering with each other in motion.

[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 , and 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 to monitor the ice condition of the split conductor 6, and the monitoring module 7 is wirelessly connected to the communication module. The monitoring module 7 includes a video collector.

[0049] It should be noted that, in actual applications, technicians in this field may choose to use a tension sensor to replace the video collector to monitor the stress state of the conductor and 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 deicing device further includes a displacement feedback module 8 electrically connected to the control module 3, the displacement feedback module 8 is fixed on the support beam 11, and the displacement feedback module 8 is used to measure the swing displacement state of the first wire. Specifically, the displacement feedback module 8 includes a distance measuring sensor, which is installed on the support beam 11 and aligned with the movable connection end 111 to measure in real time the distance between the movable connection end 111 and the distance measuring sensor when the movable connection end 111 swings left and right on the support beam 11.

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

[0053] In addition, if Figure 1 and Figure 2As shown, the deicing device in the embodiment of the present invention further includes a shell 13, which is fixed on the support bracket 12. The shell 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 of the embodiment of the present invention is as follows:

[0055] When the de-icing device performs 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, and the control module 3 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 axially pull the impact head 23 and then compress the coil spring 26, so that the impact head 23 reaches 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 is released: when the ice thickness on the second branch line 62 reaches the 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 have found that the longitudinal swing of a transmission line usually causes a change in the tension on the transmission line, which may exceed the designed load-bearing capacity of the transmission line, causing the transmission line to be overstretched and thus increasing the risk of fracture. In contrast, the transmission line has a stronger structural strength in the horizontal direction and can better withstand the lateral impact swing.

[0059] Therefore, compared with the existing de-icing devices with longitudinal vibration, 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 violent swinging 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 lateral 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 line 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 line 61 to suppress the swing of the first branch line 61.

[0062] It should be noted that, due to the reverse force applied to the fixed connection end 112 fixed on the second branch line 62 , the second branch line 62 is simultaneously subjected to the effect of impact deicing or swing suppression.

[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 also provides a control method for the deicing device in Embodiment 1, and the control method 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 the set threshold range, the control module 3 adjusts and controls the elastic impact component to the working position of elastic energy storage;

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

[0070] It can be understood 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 range, the control module 3 controls the first motor 24 not to operate. That is, the ice thickness on the split conductor 6 does not reach the condition for triggering the de-icing device to start, and there is no need to adjust the elastic impact component for energy storage preparation, so that the coil spring 26 is in a natural extension state to maintain good elastic performance.

[0072] Specifically, in step S1 , the ice thickness is fed back by a 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 whether the de-icing device performs automatic de-icing, and 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] Exemplarily, when the ice coating thickness of the split conductor 6 is 5 mm, the ice coating thickness 5 mm is within the threshold range of 4 mm-6 mm, and the control module 3 is used to adjust and control the elastic impact component to the working position of elastic energy storage in advance.

[0076] Among them, 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 is close to 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 be locked and connected with the impact head 23;

[0080] Specifically, the control module 3 adjusts and utilizes the second motor drive of 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 is used to drive 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 with 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 then compress the coil spring 26, so that the impact head 23 reaches a preset energy storage 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] Exemplarily, when the ice coating thickness of the split conductor 6 is 6.1 mm, the de-icing device is triggered to release elastic energy to perform vibration de-icing.

[0086] See also 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 in the horizontal direction by the coil spring 26 and then hits the first branch line 61 for vibration deicing.

[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 the 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 used to determine the passive telescopic state of the movable connection end 111 on the support beam 11 through the displacement feedback module 8 installed on the support beam 11 to feed back the swing information of the first branch line 61;

[0093] In step S5, the swing information includes the horizontal displacement of the branch line of the impacted split conductor 6, that is, the difference between the maximum and minimum distances between the active connection terminal 111 and the ranging sensor fed back by the ranging sensor is used to determine the magnitude of the horizontal displacement. The threshold value 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 value, 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] Exemplarily, 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 swings violently, the elastic impact component is adjusted to the energy storage gear according to the horizontal displacement, and when the first branch line 61 moves to the horizontal displacement center and swings toward the impact head 23, the impact head 23 is released to impact the swinging first branch line 61. That is, an impulse opposite to the movement of the first branch line 61 is applied to suppress the swing of the first branch line 61 as soon as possible, 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 component to the energy storage gear and releasing the impact head 23 is the same as the above-mentioned steps S2 and S3 operation steps, so it is not repeated.

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

[0097] For example, when the horizontal displacement of the swing of the first branch line 61 after deicing is 3 cm, which is less than the threshold value of 5 cm, the elastic impact component is not adjusted. That is, 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 is relied on to freely swing in the air to consume vibration energy to 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.
