Description

Technical Field

[0001] The present application relates to the technical field of electric power operation and maintenance, and in particular to an electric wire deicing device for electric power operation and maintenance. Background Art

[0002] Wire icing refers to the phenomenon that cold raindrops come into contact with lower temperature wires, condense into ice, and wrap around the surface of the wires. This phenomenon can affect the use of the wires, and deicing equipment is needed to remove the ice from the wires.

[0003] Some existing de-icing devices are mainly composed of a shell, an active running wheel and a scraper. When in use, the shell is put on the wire, and then the active running wheel is used to rotate and contact the wire, thereby realizing the function of the shell moving on the wire. In this process, the scraper is synchronously driven by the shell, and then contacts the ice covering the wire in the moving direction, so that the ice covering the wire is broken by the moving scraper and separated from the wire. Through the above actions, the de-icing operation of the wire is realized.

[0004] However, in the above process, since the ice covering the surface of the wire at a close distance is mostly similar to a whole, when the scraper contacts the ice and gradually breaks it, the force applied by the scraper on the ice will be transmitted to the above-mentioned whole ice. Since the adhesion area between the ice and the wire is large, the scraper is easily subject to a large movement resistance, which in turn affects the de-icing effect of the wire. Summary of the invention

[0005] The present application proposes a wire deicing device for power operation and maintenance, which has the advantage of reducing the resistance encountered during deicing, and is used to solve the problem that the deicing effect of the wires is affected due to the large resistance encountered during deicing.

[0006] To achieve the above-mentioned purpose, the present application adopts the following technical solution: a wire deicing device for power operation and maintenance, comprising: an upper casing, a lower casing is arranged below the upper casing, the upper casing and the lower casing are fixedly connected by bolts, the upper casing and the lower casing together form a sleeve structure, and the upper casing and the lower casing are sleeved on the outer side of the wire;

[0007] A telescopic rod No. 1 is fixedly installed on the upper side of the upper shell, and a mounting seat is fixedly installed on the end of the output rod of the telescopic rod No. 1, and clamping plates are slidably installed in the groove body of the mounting seat and on both sides of the electric wire, and a telescopic rod No. 2 is fixedly installed in the groove body of the mounting seat and between the two clamping plates, and output rods are arranged at both ends of the telescopic rod No. 2, and the output rod of the telescopic rod No. 2 is fixedly connected with the clamping plates in corresponding directions.

[0008] Furthermore, an upper half ring is slidably engaged with the interior of the upper shell and at a position close to the mounting seat, and a lower half ring is slidably engaged with the interior of the lower shell and at a position close to the mounting seat, and the upper half ring and the lower half ring together constitute a ring body structure, and the inner side surface of the ring body structure is slidably connected with the outer side surface of the wire, and the ring body structure extends out of the upper shell and the lower shell on the side facing the mounting seat, and contact teeth are fixedly installed at equal intervals on the side of the ring body structure facing away from the mounting seat, and a roller is rotatably installed inside the upper shell and at a position on the side of the upper half ring facing away from the mounting seat, and the lower side of the roller contacts the wire, and a gear is rotatably installed inside the upper shell and at a position on one side of the roller, and the rotating shaft of the roller is fixedly connected to the center position of the gear, and the gear is meshed with the contact teeth.

[0009] Furthermore, ice-breaking pieces are fixedly installed at equal intervals in the circumferential direction on the side of the ring structure facing the mounting seat, so as to push ice-covered wires away from the wires.

[0010] Furthermore, inclined plates are symmetrically fixedly installed on the opposite sides of the two clamping plates to increase the clamping area of ​​the wires.

[0011] Furthermore, rotating posts are equidistantly arranged inside the inclined plate, and the rotating posts protrude out of the inclined plate toward one side of the electric wire.

[0012] Furthermore, ice-removal openings are provided inside the clamping plate and at positions corresponding to the inclined plate to remove ice from the plate.

[0013] Furthermore, an inclined plate extends out from one end of the rotating column toward the upper shell, and a pointed end of the rotating column toward the upper shell is provided to prevent ice-covered rotation.

[0014] Furthermore, the rotating column forms a sliding connection with the inclined plate, and the inclined plate protrudes from the side of the rotating column facing away from the wires, and a fixing rod is fixedly installed on the lower side of the mounting seat and at the position of the clamping plate facing away from the wires, and a deflection member is hingedly connected to the position of the fixed rod facing the corresponding de-icing port, and the end of the deflection member facing away from the fixed rod is an arc-shaped rough end, and the arc-shaped rough end of the deflection member passes through the corresponding de-icing port and contacts with the side of the inclined plate facing away from the wires, and a spring is provided at the angle between the deflection member and the fixed rod, and the two ends of the spring are respectively fixedly connected to the deflection member and the fixed rod.

[0015] This application has the following beneficial effects:

[0016] The present application provides a wire deicing device for power operation and maintenance. By arranging an upper shell, a lower shell, a No. 1 telescopic rod, a No. 2 telescopic rod and a clamping plate, the No. 1 telescopic rod is intermittently extended, and drives the No. 2 telescopic rod and the clamping plate to move forward on the wire. Then, the No. 2 telescopic rod drives the clamping plate to contact and clamp the wire, so that the ice at the contact position between the wire and the clamping plate is broken. Then, the No. 1 telescopic rod is contracted and pulls the upper shell and the lower shell forward, and the two moving forward cooperate with the clamping plate to crush the ice between the three. Through the above actions, the adhesion area between the overall ice and the wire is reduced, so that the resistance to deicing is reduced.

[0017] Through the arrangement of the clamping plate and the inclined plate, when the clamping plate contacts and clamps the wire, the inclined plate will be driven to contact the wire synchronously. Since the position where the inclined plate contacts the wire is on the upper and lower sides of the wire, the ice on the surface of the wire corresponding to the position where the inclined plate contacts the wire is more likely to break and move along the surface of the wire when the inclined plate applies force, causing the wire to directly contact the inclined plate. Through this action, the upper shell and the lower shell are prompted to move forward smoothly, so that the de-icing efficiency is not easily affected.

[0018] Through the arrangement of the upper half ring, the lower half ring and the ice-breaking member, in the process of the upper shell and the lower shell moving forward cooperating with the clamping plate to crush the ice between the three, the upper half ring and the lower half ring will drive the ice-breaking member to rotate, so that the above-mentioned ice is broken and the rotating ice-breaking member is pushed away from the wire, thereby reducing the probability of residual ice on the surface of the wire, so that the de-icing effect is better. At the same time, since the ice-breaking member rotates and the clamping plate and the inclined plate are relatively fixed, the ice between the three is not only subjected to the extrusion force, but also to the rotational grinding force of the ice-breaking member, which makes the ice easier to break, so that the de-icing effect of the wire is further improved.

[0019] By setting the inclined plate, the rotating column and the deflection member, since the rotating column forms a protrusion on the surface of the inclined plate, when the inclined plate contacts the wire, the rotating column can more easily pass through the ice and contact the wire, so that the subsequent upper shell and the lower shell can move forward smoothly. At the same time, the tip of the rotating column is set, the ice is easier to be fixed, and the grinding force applied by the ice-breaking member is better transferred to the ice, so that the deicing effect of the wire is improved. In addition, in the process of the inclined plate clamping the wire or the inclined plate resetting, the inclined plate will drive the rotating column to move synchronously, so that the deflection member contacts and moves the rotating column, so that the rotating column rotates. Through this action, not only the residual ice between the rotating columns can be separated, but also the residual ice moved to the side of the inclined plate facing away from the wire can be guided, so that the residual ice at this position can be separated synchronously.

DETAILED DESCRIPTION

[0030] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0031] Example 1: Please refer to Figure 1-Figure 4A wire deicing device for electric power operation and maintenance comprises an upper casing 1, a lower casing 2 is arranged below the upper casing 1, the upper casing 1 and the lower casing 2 are fixedly connected by bolts, the upper casing 1 and the lower casing 2 together form a sleeve structure, the upper casing 1 and the lower casing 2 are sleeved on the outer position of the wire, a No. 1 telescopic rod 3 (such as a combination of an electric-controlled telescopic cylinder and an output rod in the prior art) is fixedly installed on the upper side of the upper casing 1, a mounting seat 4 is fixedly installed at the end of the output rod of the No. 1 telescopic rod 3, a clamping plate 5 is slidably installed in the groove body of the mounting seat 4 and located at both sides of the wire, a No. 2 telescopic rod 6 (such as a combination of an electric-controlled telescopic cylinder and an output rod in the prior art) is fixedly installed in the groove body of the mounting seat 4 and located between the two clamping plates 5, both ends of the No. 2 telescopic rod 6 are provided with output rods, and the output rod of the No. 2 telescopic rod 6 is fixedly connected to the clamping plate 5 in the corresponding direction (the above-mentioned No. 1 telescopic rod 3 and No. 2 telescopic rod 6 both have their own power supplies and are controlled by remote control, and the power supply and remote control means are both prior art, not shown in the figure).

[0032] When in use, the upper shell 1 and the lower shell 2 are combined and fixedly sleeved on the outer side of the wire (the position of the wire is not covered with ice), and then the No. 1 telescopic rod 3 is intermittently extended, and drives the mounting seat 4, the No. 2 telescopic rod 6 and the clamping plate 5 to move forward above the wire. When the No. 1 telescopic rod 3 is extended for a certain distance and then stops, at this time, the No. 2 telescopic rod 6 drives the clamping plate 5 to contact and clamp the wire, so that the ice at the contact position between the wire and the clamping plate 5 is broken. After that, the No. 1 telescopic rod 3 is retracted and pulls the upper shell 1 and the lower shell 2 forward, and the two moving forward cooperate with the clamping plate 5 to crush the ice between the three. Through the above action, the adhesion area between the overall ice and the wire is reduced (because part of the ice is crushed by the clamping plate 5, only the ice between the upper shell 1, the lower shell 2 and the clamping plate 5 is approximately the whole), so that the resistance to deicing is reduced.

[0033] See also Figure 1-Figure 4 An upper half ring 7 is slidably connected inside the upper shell 1 and close to the mounting seat 4, and a lower half ring 8 is slidably connected inside the lower shell 2 and close to the mounting seat 4. The upper half ring 7 and the lower half ring 8 together constitute a ring body structure, and the inner side of the ring body structure is slidably connected to the outer side of the wire. The ring body structure extends out of the upper shell 1 and the lower shell 2 on the side facing the mounting seat 4. Ice-breaking pieces 9 are fixedly installed equidistantly on the side of the ring body structure facing the mounting seat 4. Contact teeth 10 are fixedly installed equidistantly on the side of the ring body structure facing the mounting seat 4. A roller 11 is rotatably installed inside the upper shell 1 and at a position on the side of the upper half ring 7 facing away from the mounting seat 4. The lower side of the roller 11 contacts the wire, and a gear 12 is rotatably installed inside the upper shell 1 and at a position on one side of the roller 11. The rotating shaft of the roller 11 is fixedly connected to the center position of the gear 12, and the gear 12 is meshed with the contact tooth 10.

[0034] In the process of the upper and lower shells 1 and 2 moving forward cooperating with the clamping plate 5 to crush the ice between the three, the roller 11 rotates due to the friction between the wires, and drives the contact teeth 10, the upper half ring 7, the lower half ring 8 and the ice-breaking member 9 to rotate through the gear 12, so that the ice is crushed and at the same time, it is pushed away from the wire by the rotating ice-breaking member 9 (because the roller 11 is affected by the connecting force between the upper and lower shells 1 and 2, and is always in contact with the surface of the wire. At the same time, the contraction action of the No. 1 telescopic rod 3 drives the upper shell 1 close to the clamping plate 5, so that the rotation action of the roller 11 will continue), thereby reducing the probability of residual ice on the surface of the wire, so that the de-icing effect of the wire is better. At the same time, since the ice-breaking member 9 rotates and the clamping plate 5 is relatively fixed, the ice between the two is not only subjected to the extrusion force, but also to the rotation grinding force of the ice-breaking member 9, which makes the ice easier to break, so that the de-icing effect of the wire is further improved.

[0035] Example 2: Please refer to Figure 1-Figure 7 This embodiment is a further improvement of the first embodiment, and the improvement lies in that the two opposite sides of the two clamping plates 5 are fixedly mounted with inclined plates 13 symmetrically up and down.

[0036] When the clamping plate 5 contacts and clamps the wire, it will drive the inclined plate 13 to contact the wire synchronously. Since the inclined plate 13 contacts the wire at the upper and lower sides of the wire, and the cross-section of the wire is approximately a circular cross-section, the ice on the surface of the wire is more likely to break and move along the surface of the wire when the force is applied by the inclined plate 13, so that the wire is in direct contact with the inclined plate 13. Through this action, the upper shell 1 and the lower shell 2 are prompted to move forward smoothly, so that the de-icing efficiency is not easily affected.

[0037] See also Figure 1-Figure 7 Rotating posts 14 are equidistantly arranged inside the inclined plate 13 , and the rotating posts 14 protrude out of the inclined plate 13 toward one side of the electric wire.

[0038] Since the rotating post 14 forms a protrusion on the surface of the inclined plate 13 facing the wire, when the inclined plate 13 contacts the wire, the rotating post 14 can more easily penetrate the ice and contact the wire, thereby indirectly improving the clamping effect of the clamping plate 5 on the wire.

[0039] See also Figure 1-Figure 7 Ice-removing openings 15 are provided in the interior of the clamping plate 5 and at positions corresponding to the inclined plate 13 .

[0040] In the process of crushing the ice by the clamping plate 5, the inclined plate 13, the upper shell 1, the lower shell 2 and the ice-breaking member 9, part of the ice will move to the side of the inclined plate 13 facing away from the wires. By setting the ice-removing opening 15 and utilizing the gravity of the ice itself, the ice will slide out of the ice-removing opening 15 along the inclined plate 13, thereby reducing the accumulation of ice on the device and preventing the load on the wires from increasing.

[0041] One end of the rotating post 14 facing the upper casing 1 extends out of the inclined plate 13 , and one end of the rotating post 14 facing the upper casing 1 is set as a pointed end.

[0042] The tip of the rotating column 14 is set to make the ice easier to fix (in the process of gradually crushing the ice between the rotating column 14 and the ice-breaking member 9, as the ice area gradually decreases, it is easy for the ice to detach from the wire, but still be connected to the outside of the wire. At this time, the rotation of the ice-breaking member 9 will only drive the ice to rotate synchronously, resulting in the ice being unable to accept the rotational grinding force of the ice-breaking member 9. The tip of the rotating column 14 contacts the ice, making it easier to fix), thereby enabling the grinding force applied by the ice-breaking member 9 to be better transferred to the ice, thereby improving the de-icing effect of the wire.

[0043] See also Figure 1-Figure 7 The rotating column 14 is slidably connected with the inclined plate 13, and the side of the rotating column 14 facing away from the wire protrudes from the inclined plate 13. A fixing rod 16 is fixedly installed on the lower side of the mounting seat 4 and located at the position of the clamping plate 5 facing away from the wire. The fixing rod 16 is hinged with a deflection member 17 facing the corresponding de-icing port 15. The end of the deflection member 17 facing away from the fixing rod 16 is an arc-shaped rough end. The arc-shaped rough end of the deflection member 17 passes through the corresponding de-icing port 15 and contacts with the side of the inclined plate 13 facing away from the wire. A spring 18 is provided at the angle between the deflection member 17 and the fixing rod 16, and one end of the spring 18 is fixedly connected to the deflection member 17, and the other end of the spring 18 is fixedly connected to the fixing rod 16.

[0044] When the inclined plate 13 clamps the wire or resets the inclined plate 13, the inclined plate 13 will drive the rotating column 14 to move synchronously, so that the deflecting member 17 contacts and moves the rotating column 14 (when the inclined plate 13 approaches the fixed rod 16, the deflecting member 17 will further pass through the de-icing port 15 and move along the inclined surface of the inclined plate 13. At this time, the deflecting member 17 compresses the corresponding spring 18, so that when the deflecting member 17 moves along the inclined surface of the inclined plate 13, it can always fit and contact the rotating column 14, thereby moving the rotating column 14. When the inclined plate 13 is away from the fixed rod 16, the deflecting member 17 will gradually break away from the de-icing port 15 and move along the inclined surface of the inclined plate 13. At this time, the corresponding spring 18 gradually releases its elastic force), so that the rotating column 14 rotates. Through this action, not only can the residual ice between the rotating columns 14 be separated, but also the residual ice moved to the side of the inclined plate 13 facing away from the wire can be guided, so that the residual ice at this position can be separated synchronously.
