Description

Technical Field

[0001] This utility model relates to the field of cable de-icing technology, specifically a cable de-icing device. Background Technology

[0002] The emergence of intelligent cable de-icing robots aims to address the power supply safety hazards caused by ice and snow covering cables in winter. Cables are easily damaged by ice and snow in low-temperature environments, reducing their conductivity and even causing damage. Traditional de-icing methods are often inefficient and labor-intensive; manual de-icing is not only time-consuming and labor-intensive but also poses certain safety risks.

[0003] Most existing mechanical cable de-icing robots use a single de-icing method during de-icing operations, such as breaking the ice layer attached to the cable by rotating and striking or clamping and striking. However, since the ice layer may remain attached to the cable after breaking, the method of breaking the ice layer by striking cannot completely remove the ice layer. Moreover, a single de-icing method cannot guarantee the de-icing effect. Utility Model Content

[0004] The purpose of this invention is to provide a cable de-icing device. First, a moving component brings the device into contact with the cable and drives it to move along the cable. Then, a driving component reverses the rotation shaft and the sleeve, and a rubber rod simultaneously strikes the cable from both sides to ensure even force on the ice layer and prevent localized ice blocks from failing to detach due to unilateral force. Simultaneously, during the movement of the lower housing, the movable seat at the top of the lower housing oscillates periodically through a swing component, which, together with the fixed tube and the striking seat, strikes the ice layer again from above the cable, causing any remaining ice blocks to completely detach, thus solving the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a cable de-icing device, comprising:

[0006] Lower housing;

[0007] The top of the lower housing is hinged to a movable seat, and the interior of the movable seat is rotatably connected to a rotating shaft via bearings. The front and rear ends of the movable seat are rotatably connected to sleeves fitted on the outside of the rotating shaft via bearings. Rubber rods are fixed to the outside of both the sleeves and the rotating shaft. The interior of the movable seat is provided with a drive assembly that drives the rotating shaft and the sleeves in the opposite direction.

[0008] The top of the lower housing is provided with a swinging component that swings the movable seat back and forth. The front and rear ends of the movable seat are fixed with a fixed tube sleeved on the outside of the sleeve. A striking seat for striking the cable is fixed below the fixed tube.

[0009] The lower housing is internally equipped with a moving component that clamps the cable to the outside of the lower housing.

[0010] Preferably, the drive assembly includes a first motor fixed inside the movable seat, a first drive gear fixed to the output shaft of the first motor, a first driven gear meshing with the first drive gear fixed to the outer side of the rotating shaft, connecting bevel gears fixed to the outer sides of the sleeve and the rotating shaft, and a transition bevel gear meshing with both sets of connecting bevel gears rotatably connected to the inner cavity of the movable seat.

[0011] Preferably, the yaw assembly includes a drive shaft and a driven shaft rotatably connected to the top of the lower housing via a mounting base. A second motor, fixedly connected to one end of the drive shaft, is fixed at the center of the top of the lower housing. A first pulley is fixed to the outer side of the drive shaft and the driven shaft. Two sets of the first pulleys are connected by a first synchronous belt. Protrusions are fixed at both ends of the driven shaft. The end of the protrusion away from the driven shaft moves against the bottom of the movable seat. Two sets of support springs are fixed to one side of the top of the lower housing. The top of the support spring is fixed to the bottom of the movable seat away from the protrusion.

[0012] Preferably, the moving component includes two sets of clamping frames movably disposed within the inner cavity of the lower housing. Inside each clamping frame, two sets of drive rollers in contact with the cable are rotatably connected via bearings. A third motor is fixed to the outer side of each clamping frame. A second pulley is fixed to both the output shaft of the third motor and the drive rollers. A second synchronous belt is drively connected to the outer side of each second pulley. A movable frame is movably disposed above each clamping frame. A limit roller is rotatably connected to the bottom of the movable frame via bearings. A fixing block with a guide groove is fixed to the top of each clamping frame. A guide post slidably disposed inside the guide groove is fixed to the end of the movable frame.

[0013] Preferably, connecting rods are fixed around the top of the movable frame, and the top of the connecting rods extends through to the top of the lower housing and is fixed with a limiting plate.

[0014] Preferably, a fixing frame is fixed to the bottom of both sides of the lower housing, and a counterweight is provided in the fixing frame.

[0015] Preferably, the clamping frame has a guide shaft rotatably connected inside via a bearing, and the guide shaft is connected to a second synchronous belt drive.

[0016] Preferably, a protective shell is fixed to the outside of the movable seat, and the protective shell is sleeved on the outside of the lower shell.

[0017] Compared with the prior art, the beneficial effects of this utility model are:

[0018] 1. This utility model uses a drive assembly to drive the rotating shaft and sleeve in reverse, which allows rubber rods fixed to the outside of the rotating shaft and sleeve to strike the ice layer on the cable from both sides, so that the ice layer is broken evenly by force. Then, the swing assembly drives the movable seat to swing on the top of the lower housing, and the striking seat strikes the front and rear sides of the cable to shake off the remaining ice fragments. By using multiple methods to remove the ice layer on the cable, not only can the ice layer be completely removed, but the de-icing efficiency is also improved.

[0019] 2. This utility model facilitates the connection between the movable frame and the lower housing by setting up a connecting rod and a limiting plate. When the device is placed on the cable, the weight of the device itself causes the movable frame to move upward on the lower housing. Then, the movable frame, through the cooperation of the guide post and the guide groove, causes the clamping frames on both sides to drive the drive roller to clamp the cable. With the help of the limiting roller on the movable frame, the device is stably clamped on the outside of the cable, which facilitates the driving of the device. Attached Figure Description

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] This utility model provides, for example Figures 1-7 The cable de-icing device shown includes:

[0030] Lower housing 1;

[0031] The top of the lower housing 1 is hinged to a movable seat 2. The interior of the movable seat 2 is rotatably connected to a rotating shaft 3 via bearings. The front and rear ends of the movable seat 2 are rotatably connected to a sleeve 4 sleeved on the outside of the rotating shaft 3 via bearings. Rubber rods 5 are fixed to the outside of both the sleeve 4 and the rotating shaft 3. The interior of the movable seat 2 is provided with a drive assembly 6 that drives the rotating shaft 3 and the sleeve 4 in the opposite direction.

[0032] The top of the lower housing 1 is provided with a swing assembly 7 for swinging the movable seat 2 back and forth. The front and rear ends of the movable seat 2 are fixed with a fixing tube sleeved on the outside of the sleeve 4. The bottom of the fixing tube is fixed with a striking seat 8 for striking the cable.

[0033] The lower housing 1 is internally provided with a moving component 9 that clamps the outside of the cable and moves the lower housing 1.

[0034] The rotating shaft 3 and the sleeve 4 are driven in reverse by the drive component 6, which makes it convenient for the rubber rods 5 fixed on the outside of the rotating shaft 3 and the sleeve 4 to strike the ice layer on the cable from both sides, so that the ice layer is broken by uniform force. Then, the swing component 7 drives the movable seat 2 to swing on the top of the lower housing 1, and the striking seat 8 strikes the front and back sides of the cable to shake off the remaining ice fragments. By using multiple methods to remove the ice layer on the cable, not only can the ice layer be completely removed, but the de-icing efficiency is also improved.

[0035] Among them, such as Figure 3 As shown:

[0036] The drive assembly 6 includes a first motor 61 fixed inside the movable seat 2. The output shaft of the first motor 61 is fixed with a first drive gear 62. The outer side of the rotating shaft 3 is fixed with a first driven gear 63 that meshes with the first drive gear 62. The outer sides of the sleeve 4 and the rotating shaft 3 are both fixed with connecting bevel gears 64. The inner cavity of the movable seat 2 is rotatably connected with a transition bevel gear 65 that meshes with both sets of connecting bevel gears 64. The first motor 61 drives the first drive gear 62 to rotate. Then, the first drive gear 62 drives the rotating shaft 3 through the first driven gear 63. When the rotating shaft 3 rotates, the sleeve 4 is driven to rotate in the opposite direction by the cooperation of the transition bevel gear 65 and the connecting bevel gear 64. This causes the two sets of rubber rods 5 on the outer side of the movable seat 2 to move from both sides towards each other and strike the ice layer on the outer side of the cable. The ice layer is evenly stressed and breaks.

[0037] Furthermore, such as Figure 4 As shown:

[0038] The yaw assembly 7 includes a drive shaft 71 and a driven shaft 72 rotatably connected to the top of the lower housing 1 via a mounting base. A second motor 73, fixedly connected to one end of the drive shaft 71, is fixed at the center of the top of the lower housing 1. First pulleys 74 are fixed to the outer sides of the drive shaft 71 and the driven shaft 72. Two sets of first pulleys 74 are connected by a first synchronous belt 75. Protrusions 76 are fixed at both ends of the driven shaft 72. The end of the protrusion 76 away from the driven shaft 72 moves against the bottom of the movable seat 2. Two sets of support springs 77 are fixed to one side of the top of the lower housing 1. The top of the support springs 77 is fixed to the bottom of the movable seat 2 away from the protrusions 76. The second motor 73 drives the motor 73 to rotate. The drive shaft 71 is rotated, and then the first pulley 74 and the first synchronous belt 75 on the drive shaft 71 and driven shaft 72 drive the driven shaft 72. Then the driven shaft 72 drives the protrusion 76 to rotate and lift one side of the movable seat 2, causing the movable seat 2 to swing. At the same time, the other side squeezes the support spring 77. When the protrusion 76 separates from the movable seat 2, the energy stored in the support spring 77 reverses and drives the support spring 77 to rebound, causing the movable seat 2 to deflect in the opposite direction again. This causes the movable seat 2 to swing periodically. Through the striking seat 8 on the movable seat 2, the cable is intermittently struck, and the vibration removes the residual ice fragments on the cable.

[0039] Preferred, such as Figure 5-7 As shown:

[0040] The moving component 9 includes two sets of clamping frames 91 movably disposed within the inner cavity of the lower housing 1. Inside each clamping frame 91, two sets of drive rollers 92, which are in contact with cables, are rotatably connected via bearings. A third motor 93 is fixed to the outer side of each clamping frame 91. Second pulleys 94 are fixed to both the output shaft of the third motor 93 and the drive rollers 92. A second synchronous belt 95 is drively connected to the outer side of each second pulley 94. A movable frame 96 is movably disposed above each clamping frame 91. A limit roller 97 is rotatably connected to the bottom of the movable frame 96 via bearings. A belt is fixed to the top of each clamping frame 91. The fixed block 99 has a guide groove 98, and the end of the movable frame 96 is fixed with a guide post 910 that is slidably disposed inside the guide groove 98. The third motor 93 drives the drive roller 92 through the second pulley 94 and the second synchronous belt 95, so that the drive roller 92 can drive the device to move after contacting the cable. The guide post 910 is connected to the guide groove 98 on the fixed block 99 to realize the movable connection between the movable frame 96 and the clamping frame 91. When the movable frame 96 is squeezed upward by the cable, the clamping frame 91 moves to the middle to clamp and fix the cable.

[0041] It is worth noting that, such as Figure 5-6 As shown:

[0042] Connecting rods 10 are fixed around the top of the movable frame 96. The top of the connecting rods 10 extends through to the top of the lower housing 1 and is fixed with a limiting plate 11. The connection rods 10 and the limiting plate 11 facilitate the connection between the movable frame 96 and the lower housing 1. When the device is placed on the cable, the weight of the device itself causes the movable frame 96 to move upward on the lower housing 1. Then, the movable frame 96, through the cooperation of the guide post 910 and the guide groove 98, causes the clamping frames 91 on both sides to drive the drive roller 92 to clamp the cable. With the help of the limiting roller 97 on the movable frame 96, the device is stably clamped on the outside of the cable, which facilitates the driving of the device.

[0043] In a further preferred embodiment, such as Figure 1-2 As shown:

[0044] The bottom of both sides of the lower housing 1 is fixed with a fixed frame 12, and a counterweight 13 is set in the fixed frame 12. The fixed frame 12 makes it easy to store the counterweight 13. The counterweight 13 is used to lower the center of gravity of the device to below the height of the cable, so that the device is more stable on the cable and prevents the device from tipping over and falling due to the influence of the external environment.

[0045] In addition, such as Figure 7 As shown:

[0046] Inside the clamping frame 91, a guide shaft 14 is rotatably connected via a bearing. The guide shaft 14 is connected to the second synchronous belt 95. The guide shaft 14 facilitates the guidance of the second synchronous belt 95, preventing the ice crushed by the drive roller 92 from falling and adhering to the second synchronous belt 95, thus affecting its operation.

[0047] In this embodiment, as Figure 1 As shown:

[0048] A protective shell 15 is fixed to the outside of the movable seat 2. The protective shell 15 is sleeved on the outside of the lower shell 1. The protective shell 15 is used to protect the structure between the movable seat 2 and the lower shell 1, and to prevent ice fragments from splashing and adhering to the parts, thus affecting the normal operation of the equipment.

[0049] In practical use, the device is lifted above the cable using a drone, and then the drone is controlled to move the cable from the bottom of the lower housing 1 into the interior. When the device is placed on the cable, the cable contacts the limiting roller 97 on the movable frame 96. The weight of the device itself causes it to move downwards, making the movable frame 96 move upwards relative to the lower housing 1. Then, the movable frame 96, through the cooperation of the guide post 910 and the guide groove 98, uses the fixing block 99 to close the clamping frames 91 on both sides towards the middle, so that the drive roller 92 on the clamping frame 91 contacts the cable. The third motor 93 is started, and then the third motor 93 drives the second pulley 94 to rotate, which, together with the second synchronous belt 95, rotates the drive roller 92, causing the device to move on the cable. At the same time, the first motor 61 drives the first drive gear 62 to rotate. The first drive gear 62 drives the rotating shaft 3 through the first driven gear 63. Meanwhile, the sleeve passes through the transition bevel gear 65 and the connecting bevel gear 64. In conjunction with the rotating shaft 3, the sleeve 4 and the rubber rod 5 on the rotating shaft 3 strike the ice layer on the cable from both sides, causing the ice layer to break evenly on both sides. Then, the second motor 73 drives the drive shaft 71, which in turn drives the driven shaft 72 to rotate through the first pulley 74 and the first synchronous belt 75. The driven shaft 72 drives the protrusion 76 to rotate. When the protrusion 76 contacts one side of the bottom of the movable seat 2 and lifts one side of the movable seat 2, the movable seat 2 swings. At the same time, the other side of the movable seat 2 moves down and squeezes the support spring 77. When the protrusion 76 separates from the movable seat 2, the support spring 77 lifts the movable seat 2 on the lower side, causing the movable seat 2 to swing periodically. During the swing of the movable seat 2, the striking seat 8 connected to the movable seat 2 through the fixed tube strikes the cable from above, causing the cable to vibrate and shake off some ice fragments, ensuring the efficiency and quality of cable de-icing.

[0050] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
