Description

Technical Field

[0001] This utility model relates to the field of cable maintenance device technology, and in particular to a de-icing device for high-altitude cable maintenance. Background Technology

[0002] Power towers, cables, and other electrical facilities are erected on hillsides. Due to the high altitude and low temperature, a layer of ice will cover the surface of the high-voltage cables when it snows. As time goes by, the ice layer will gradually thicken. The ice covering the surface of the high-voltage cables will seriously affect the power transmission efficiency and cause damage to the cable sheath.

[0003] In practice, maintenance personnel often knock off ice from the cable surface by tapping it. However, since some power towers are quite high, this method requires maintenance personnel to climb the tower, which not only poses a safety hazard to the personnel but also makes it difficult to knock off ice from the middle of the cable. Utility Model Content

[0004] In order to solve the above problems, the purpose of this utility model is to provide a de-icing device for high-altitude cable maintenance, which solves the problem of manually removing ice from high-altitude cables.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A de-icing device for high-altitude cable maintenance is movably mounted on the cable along its longitudinal length. It includes a drive wheel movably mounted on the upper side of the cable along the longitudinal direction, an installation assembly mounted on the drive wheel to prevent the drive wheel from falling off the cable, a de-icing assembly mounted in front of the drive wheel, and a control assembly mounted on the drive wheel to control the forward movement of the drive wheel.

[0007] The drive wheel is provided with a wrapping groove for embedding and placing cables.

[0008] The control assembly includes a drive shaft that runs through the central axis of the drive wheel from left to right, a pair of fixed plates that are respectively rotatably sleeved on the drive shaft and located on the left and right sides of the drive wheel, a placement box fixed on the right side wall of the right fixed plate, and a drive motor that is located in the placement box and whose output shaft is axially fixedly connected to the drive shaft.

[0009] The de-icing assembly includes a base fixed between two fixed plates and positioned in front of the drive wheel, an ice-cutting cone fixed to the front side of the base, a rotating motor embedded in the base, a peeling plate rotatably positioned below the base and behind the ice-cutting cone, a connecting rod fixed to the upper side of the peeling plate and extending into the base and axially fixed to the output shaft of the rotating motor, and a hot melt assembly located in the ice-cutting cone for heating the tip of the ice-cutting cone.

[0010] More preferably, the hot melt sub-assembly includes a mounting groove disposed on the lower side of the ice-cutting cone and surrounding the edge of the ice-cutting cone, a power supply embedded on the rear side of the ice-cutting cone, and a heating resistance wire disposed in the mounting groove and electrically connected to the power supply at both ends.

[0011] More preferably, the mounting assembly includes an adjusting rod rotatably mounted on the left end of the drive shaft at the front end, an anti-detachment wheel rotatably mounted on the right side of the rear end of the adjusting rod and movably mounted on the lower side of the cable, a pair of limiting plates respectively fixed on the left and right sides of the anti-detachment wheel, a plurality of connecting threaded holes arranged circumferentially on the left fixed plate, an alignment hole at the front of the adjusting rod, a fastening screw in the alignment hole for connecting the alignment hole and the corresponding connecting threaded hole, and a pair of balance blocks respectively fixed on the side of the two fixed plates away from the drive wheel.

[0012] More preferably, the outer wall of the drive wheel is provided with a plurality of anti-slip grooves arranged at intervals along the circumference.

[0013] More preferably, an upper wrapping sleeve is fixedly provided on the lower side of the base and wrapped around the upper side of the cable, and a lower wrapping sleeve is detachably provided below the upper wrapping sleeve and wrapped around the lower side of the cable.

[0014] More preferably, the left and right ends of the upper wrapping sleeve are detachably connected to the left and right ends of the lower wrapping sleeve by connecting screws.

[0015] More preferably, an ice-removing scraper is fixedly provided on the front side of the lower wrapping sleeve.

[0016] This utility model has the following beneficial effects:

[0017] 1. This utility model uses a drive wheel to move forward on the cable, and the ice-cutting cone of the de-icing assembly cuts the ice on the cable in the middle. The peeling plate then pushes the ice away from the cracks in the ice to both sides, thus removing the ice from the cable and solving the problem of manually removing ice from high-altitude cables.

[0018] 2. This utility model heats the tip of the ice-cutting cone by using a hot-melt component, thereby accelerating the segmentation of ice fragments during the ice-cutting process by using the high-temperature cone tip, thus speeding up the de-icing efficiency.

[0019] 3. This utility model places the drive wheel between two power towers by installing components, and moves along the length of the cable. At the same time, the vertical direction is restricted by the anti-detachment wheel, thus achieving a stable movement effect. Attached Figure Description

[0026] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0027] like Figure 1 , Figure 3 and Figure 4 As shown, this embodiment of a de-icing device for high-altitude cable maintenance is movably mounted on the cable 1 along its front-to-back length. It includes a drive wheel 2 movably mounted on the upper side of the cable 1 along the front-to-back direction, an installation assembly 3 mounted on the drive wheel 2 to prevent the drive wheel 2 from falling off the cable 1, a de-icing assembly 4 mounted in front of the drive wheel 2, and a control assembly 5 mounted on the drive wheel 2 to control the drive wheel 2 to move forward.

[0028] The drive wheel 2 is provided with a wrapping groove 21 for embedding and placing the cable 1;

[0029] Control component 5 includes a drive shaft 51 that runs through the central axis of the drive wheel 2 from left to right, a pair of fixing plates 52 that are respectively rotatably sleeved on the drive shaft 51 and located on the left and right sides of the drive wheel 2, a placement box 53 fixed on the right side wall of the right fixing plate 52, and a drive motor 54 that is disposed in the placement box 53 and whose output shaft is axially fixedly connected to the drive shaft 51.

[0030] The de-icing assembly 4 includes a base 41 fixed between two fixed plates 52 and positioned in front of the drive wheel 2, an ice-cutting cone 42 fixed to the front of the base 41, a rotating motor 43 embedded in the base 41, a peeling plate 44 rotatably positioned below the base 41 and behind the ice-cutting cone 42, a connecting rod 45 fixed to the upper side of the peeling plate 44 and extending into the base 41 and axially fixed to the output shaft of the rotating motor 43, and a hot melt assembly 46 disposed in the ice-cutting cone 42 and used to heat the tip of the ice-cutting cone 42.

[0031] When in use, the drive wheel 2 is mounted on the cable 1 via the mounting assembly, and the drive motor 54 drives the drive wheel 2 to rotate, thereby causing the de-icing assembly 4 to move forward on the cable 1. When the cone of the ice-cutting cone 42 contacts the ice shards, it cuts a crack in the middle of the ice shards. As the drive wheel 2 continues to move forward, the peeling plate 44 is positioned between the cracks in the ice shards. During rotation, the two ends of the peeling plate 44 push the inner walls of the ice shard cracks to the left and right sides respectively, thereby applying an outward pushing force to the ice shards from the cracks. This causes the ice shards to be separated along the cracks and pushed off the surface of the cable 1, thus achieving the de-icing effect.

[0032] like Figure 1 and Figure 3 As shown, the hot melt sub-assembly 46 includes a mounting groove 461 disposed on the lower side of the ice-cutting cone 42 and surrounding the edge of the ice-cutting cone 42, a power supply 462 embedded on the rear side of the ice-cutting cone 42, and a heating resistance wire 463 disposed in the mounting groove 461 and electrically connected to the power supply 462 at both ends.

[0033] When this product is in use, the power supply 462 is turned on, so that the current in the power supply 462 flows through the heating resistance wire 463. Due to the Joule efficiency, the heating resistance wire 463 generates heat and transfers it to the tip surface of the ice-cutting cone 42, thereby accelerating the rate at which the ice shards melt and break when the ice-cutting cone 42 comes into contact with the ice shards.

[0034] like Figure 1 and Figure 2 As shown, the mounting assembly 3 includes an adjusting rod 31 rotatably mounted on the left end of the drive shaft 51 at the front end, an anti-detachment wheel 32 rotatably mounted on the right side of the rear end of the adjusting rod 31 and movably mounted on the underside of the cable 1, a pair of limiting plates 33 respectively fixed on the left and right sides of the anti-detachment wheel 32, several connecting threaded holes 34 arranged circumferentially on the left fixed plate 52, an alignment hole 35 located at the front of the adjusting rod 31, a fastening screw 36 located in the alignment hole 35 and used to connect the alignment hole 35 with the corresponding connecting threaded hole 34, and a pair of balance blocks 37 respectively fixed on the side of the two fixed plates 52 away from the drive wheel 2.

[0035] When using this product, the operator climbs onto one side of the power tower, manually removes the ice from the front part of the cable 1 near the tower, and places the drive wheel 2 on the clean cable 1 from the right side. Then, the operator loosens the fastening screw 36, rotates the adjusting rod 31 to the rear and upper side of the drive wheel 2, causing the anti-detachment wheel 32 to rotate until it abuts against the lower rear side of the clean cable 1, and places the two limiting plates 33 on the left and right sides of the cable 1. Then, the alignment hole 35 is aligned with the corresponding connecting thread hole 34, and the fastening screw 36 is screwed in and tightened to complete the installation and fixation. This restricts the up and down movement of the drive wheel 2 on the cable 1, achieving the effect of limiting the movement position of the drive wheel 2 and achieving the purpose of stable installation. The setting of the balance block 37 prevents the device from swaying left and right when moving on the cable 1, which could cause the device to tilt.

[0036] like Figure 1 , Figure 2 and Figure 4 As shown, the outer wall of the drive wheel 2 is provided with several anti-slip grooves 22 arranged at intervals along the circumference.

[0037] When using this product, the anti-slip groove 22 is designed to prevent the drive wheel 2 from slipping on the wet cable 1.

[0038] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, an upper wrapping sleeve 6 is fixedly provided on the lower side of the base 41, which wraps around the upper side of the cable 1, and a lower wrapping sleeve 7 is detachably provided below the upper wrapping sleeve 6, which wraps around the lower side of the cable 1.

[0039] When this product is in use, after the device is placed on the cable 1, the installation of the lower wrapping sleeve 7 causes the device to be limited by the upper wrapping sleeve 6 and the lower wrapping sleeve 7 wrapping the outer wall of the cable 1, thereby preventing the device from falling off the cable 1 during the de-icing process.

[0040] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the left and right ends of the upper wrapping sleeve 6 are detachably connected to the left and right ends of the lower wrapping sleeve 7 via connecting screws 8.

[0041] When using or installing this product, the lower sleeve 7 is fixedly connected to the lower sleeve 6 below by connecting screws 8 on both sides, thereby fixing the device to the cable 1 and preventing the device from falling off the cable 1.

[0042] like Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, an ice-removing scraper 9 is fixedly installed on the front side of the lower sleeve 7.

[0043] When using this product, the ice cones suspended on the lower side of the outer wall of the cable 1 are scraped off by the de-icing scraper 9.

[0044] The working principle of this device is as follows:

[0045] Step 1: The operator climbs onto one side of the power tower and manually removes the ice from the front part of the cable 1 near the tower. Then, from the right side of the cable 1, the drive wheel 2 is placed on top of the clean cable 1. At this time, the upper sleeve 6 wraps around the cable 1, and then the lower sleeve 7 wraps around the lower side of the cable 1 corresponding to the upper sleeve 6, and fits snugly against the upper sleeve 6. Then, the connecting screws 8 at both ends are tightened to fix the upper sleeve 6 and the lower sleeve 7 in place.

[0046] Step 2: Loosen the fastening screw 36, rotate the adjusting rod 31 to the upper rear side of the drive wheel 2, drive the anti-detachment wheel 32 to rotate to the lower rear side of the clean cable 1, and place the two limiting plates 33 on the left and right sides of the cable 1. Then align the alignment hole 35 with the corresponding connecting thread hole 34, and then tighten the fastening screw 36 to complete the installation and fixation.

[0047] Step 3: Start the power supply 462, so that the current in the power supply 462 flows through the heating resistance wire 463. Due to the Joule efficiency, the heating resistance wire 463 generates heat and transfers it to the tip surface of the ice-cutting cone 42. Then start the rotating motor 43, which drives the connecting rod 45 to maintain circumferential rotation. Then start the drive motor 54, which drives the drive shaft 51 to rotate, thereby driving the drive wheel 2 to rotate, causing the drive wheel 2 to move forward on the cable 1.

[0048] Step 4: When the ice-cutting cone 42 reaches the ice shard, the tip of the ice-cutting cone 42 first contacts the ice shard. Under the cutting force of the tip of the ice-cutting cone 42 and the high heat of the tip surface, the ice shard that the ice-cutting cone 42 passes through is cut in the middle to form a crack. Then, as the drive wheel 2 continues to move forward, the stripping plate 44 is placed between the ice shard cracks. During the rotation, the two ends of the stripping plate 44 push the left and right sides of the inner wall of the ice shard crack to the left and right sides respectively, thereby applying an outward pushing force to the ice shard from the crack, thereby causing the ice shard to be separated along the crack and pushed off the surface of the cable 1 and fall off the cable 1, achieving the de-icing effect.
