Description

Technical Field

[0001] The utility model relates to the technical field of deicing of power transmission lines, in particular to a deicing device for power transmission lines. Background Art

[0002] Transmission lines can be divided into overhead transmission lines and cable lines. Overhead transmission lines are composed of line towers, conductors, insulators, line hardware, guy wires, tower foundations, grounding devices, etc., and are erected above the ground.

[0003] When overhead transmission lines are used in winter, they are easily affected by low temperatures and are prone to icing. Transmission lines in cities are relatively less likely to freeze due to the urban heat island effect, but the temperature in rural areas is lower, which makes transmission lines prone to icing. At the same time, if they are not cleaned, the ice will thicken and break the lines.

[0004] For example, the transmission line de-icing device with application number CN202022675346.5 includes an articulated rod, an articulated shaft and a push-pull rod. The operator holds the lower side of the two articulated rods and opens the two articulated rods so that the transmission line is located between the two arc-shaped clamping plates. At this time, the serrations bite the ice on the surface of the transmission line, and as the clamping force of the two articulated rods increases, the biting force gradually increases, breaking the ice layer on the surface of the transmission line and removing the ice layer.

[0005] During use of the de-icing device of the above patent, the operator holds the lower sides of the two hinged rods and opens the two hinged rods so that the transmission line is located between the two arc-shaped clamping plates. At this time, the serrations bite and crush the ice on the surface of the transmission line to remove the ice. Since the de-icing operation is carried out in winter and is affected by the low temperature outside, the operator will wear gloves on his hands to keep warm. This setting reduces the stability of the handheld hinged rod.

[0006] Therefore, we propose a transmission line deicing device to solve the above problems. Utility Model Content

[0007] The purpose of the present utility model is to provide a power transmission line deicing device to solve the problem raised in the above-mentioned background technology that since deicing operations are all performed in winter and are affected by the low temperature outside, the operator will wear gloves on his hands to keep warm during the operation, and such a setting will lead to a decrease in the stability of the handheld articulated rod.

[0008] To achieve the above-mentioned object, the present invention provides the following technical solution: a power transmission line deicing device, comprising a first support rod and a shaft rod movably mounted on one side of an outer wall of the first support rod, a second support rod movably mounted on the other end of the shaft rod, a clamping assembly being threadedly mounted on the upper ends of the first support rod and the second support rod, a pressing assembly being fixedly mounted on the lower ends of the outer walls of the first support rod and the second support rod, the pressing assembly being configured to press the back of an operator's hand against the outer walls of the first support rod and the second support rod, and a climbing assembly being fixedly mounted on one side of the outer wall of the clamping assembly;

[0009] The pressing assembly includes a fixing mechanism and a rebound mechanism fixedly mounted on one side of an outer wall of the fixing mechanism. The rebound mechanism is configured to adaptively press the back of an operator's hand.

[0010] Preferably, the first support rod includes a long rod and a threaded groove formed at the upper end of the long rod.

[0011] Preferably, the clamping assembly includes a semicircular plate and saw teeth embedded in the inner wall of the semicircular plate, and a threaded rod is fixedly installed in the middle of the lower end of the semicircular plate.

[0012] Preferably, the fixing mechanism includes a wrapping ring and a first rubber layer embedded around the outer wall of the wrapping ring. A U-shaped rod is fixedly installed on one side of the outer wall of the wrapping ring. A plurality of circular grooves are linearly and evenly spaced on one side of the inner wall of the U-shaped rod. An elastic element is fixedly installed in the inner cavity of the circular groove.

[0013] Preferably, the rebound mechanism includes a contact plate and a second rubber layer embedded in one side of the inner wall of the contact plate.

[0014] Preferably, the climbing assembly includes an open round block and an inclined spring fixedly mounted on the upper end of the inner wall of the open round block.

[0015] Compared with the prior art, the beneficial effects of the present invention are:

[0016] 1. Through the arrangement of the first support rod, the second support rod, the wrapping ring, the U-shaped rod, the elastic element and the contact plate, after the operator grasps the lower end of the first support rod, the contact plate will automatically press the back of the operator's hand against the outer wall of the first support rod under the elastic force of the elastic element, thereby improving the stability of the de-icing device.

[0017] 2. Through the arrangement of the semi-circular plate, threaded rod, long rod and serrations, when the serrations are damaged, the semi-circular plate can be disassembled and replaced separately. At the same time, when the de-icing device is not in use, the de-icing device can be placed by hanging the open round block on the wall nails. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0024] Example 1: Please refer to Figure 1-Figure 3 , a transmission line de-icing device includes a first support rod 1 and a shaft rod 2 movably mounted on one side of the outer wall of the first support rod 1, a second support rod 3 movably mounted on the other end of the shaft rod 2, the upper ends of the first support rod 1 and the second support rod 3 are respectively threadedly mounted with a clamping assembly 4, the lower ends of the outer walls of the first support rod 1 and the second support rod 3 are respectively fixedly mounted with a pressing assembly 5, the pressing assembly 5 is configured to be suitable for pressing the back of the operator's hand on the outer walls of the first support rod 1 and the second support rod 3, a climbing assembly 6 is fixedly mounted on one side of the outer wall of the clamping assembly 4, the climbing assembly 6 is configured to be suitable for placing the de-icing device when it is not in use, and the structure and principle of the first support rod 1 and the second support rod 3 are the same.

[0025] The pressing assembly 5 includes a fixing mechanism 51 and a rebound mechanism 52 fixedly mounted on one side of the outer wall of the fixing mechanism 51. The rebound mechanism 52 is configured to adaptively press the back of the operator's hand.

[0026] The fixing mechanism 51 includes a wrapping ring 511 and a first rubber layer 512 embedded around the outer wall of the wrapping ring 511. The wrapping ring 511 is wrapped around the lower end of the outer wall of the long rod 11. The first rubber layer 512 is set to increase the friction between the operator's palm and the long rod 11.

[0027] A U-shaped rod 513 is fixedly installed on one side of the outer wall of the wrapping ring 511, and a plurality of circular grooves 514 are linearly and evenly spaced on one side of the inner wall of the U-shaped rod 513. The circular grooves 514 are arranged to be suitable for limiting the installation of one end of the elastic element 515. The elastic element 515 is fixedly installed in the inner cavity of the circular groove 514, and one end of the elastic element 515 is fixedly installed to the outer wall of the contact plate 521.

[0028] The rebound mechanism 52 includes a contact plate 521 and a second rubber layer 522 embedded in one side of the inner wall of the contact plate 521 . The second rubber layer 522 is configured to improve the stability between the back of the operator's hand and the contact plate 521 .

[0029] In this embodiment: when using the de-icing device to de-ice the transmission line, the operator holds the wrapping ring 511 fixed to the lower ends of the first support rod 1 and the second support rod 3 with their hands respectively. Since a U-shaped rod 513 is fixedly installed on one side of the outer wall of the wrapping ring 511, a contact plate 521 is fixed to one end of the U-shaped rod 513 through an elastic element 515. After the operator holds the lower end of the first support rod 1 with his hand, the contact plate 521 will automatically press the back of the operator's hand against the outer wall of the first support rod 1 under the elastic force of the elastic element 515. This arrangement can improve the stability of the operator holding the first support rod 1 and the second support rod 3 while wearing gloves, thereby improving the stability of operating the de-icing device.

[0030] Example 2: This example is an improvement made on the basis of Example 1. For details, please refer to Figure 4 The first support rod 1 includes a long rod 11 and a threaded groove 12 opened at the upper end of the long rod 11.

[0031] The clamping assembly 4 includes a semicircular plate 41 and a serration 42 embedded in the inner wall of the semicircular plate 41. A threaded rod 43 is fixedly installed in the middle of the lower end of the semicircular plate 41. The threaded rod 43 is threadedly connected to the inner cavity of the thread groove 12 to be suitable for installing the semicircular plate 41 on the upper end of the long rod 11.

[0032] By holding the first support rod 1 and the second support rod 3 respectively and opening the first support rod 1 and the second support rod 3, the power transmission line is located between the two semicircular arc plates 41. At this time, the saw teeth 42 bite and crush the ice on the surface of the power transmission line to remove ice.

[0033] The climbing assembly 6 includes an open round block 61 and an inclined spring 62 fixedly installed on the upper end of the inner wall of the open round block 61. An inclined pressure plate 63 is fixedly installed on one end of the inclined spring 62. Through the arrangement of the inclined spring 62 and the inclined pressure plate 63, when the open round block 61 is hung on the screw, the inclined pressure plate 63 is pressed against the lower end of the screw under the elastic force of the inclined spring 62.

[0034] In this embodiment: since the lower end of the semi-circular plate 41 is threadedly mounted on the upper end of the long rod 11 through the threaded rod 43, this arrangement allows the semi-circular plate 41 to be disassembled and replaced separately after the serrations 42 are damaged. At the same time, when the de-icing device is not in use, the de-icing device can be placed by hanging the open round block 61 on the wall nail.

[0035] Working principle: When using the de-icing device to de-ice the transmission line, the operator holds the wrapping ring 511 fixed to the lower ends of the first support rod 1 and the second support rod 3 with his hands. Since a U-shaped rod 513 is fixedly installed on one side of the outer wall of the wrapping ring 511, one end of the U-shaped rod 513 is fixed with a contact plate 521 through an elastic element 515. After the operator holds the lower end of the first support rod 1 with his hand, the contact plate 521 will automatically press the back of the operator's hand against the outer wall of the first support rod 1 under the elastic force of the elastic element 515. This arrangement can improve the stability of the operator holding the first support rod 1 and the second support rod 3 while wearing gloves. Since the lower end of the semi-circular plate 41 is threadedly mounted on the upper end of the long rod 11 through the threaded rod 43, this arrangement allows the semi-circular plate 41 to be disassembled and replaced separately after the serrations 42 are damaged. At the same time, when the de-icing device is not in use, the de-icing device can be placed by hanging the open round block 61 on the wall nail.
