A microwave de-icing and water collection device for power distribution network cables

Abstract

This invention discloses a microwave ice-melting and water-collecting device for power distribution network cables, relating to the field of power distribution network cable technology. When the power distribution network cable is placed on a circular disc using a melting ice device, the increased weight of the disc causes a downward force on the spring rod, which supports the weight, thus improving stability during rotation. Then, the motor is started, causing the fixed rod to rotate under the influence of the motor, and the connecting block drives the support rod to move together. The rotation speed is low, so the power distribution network cable is not affected by centrifugal force and will not shift its position. At this time, the circular disc, under the influence of the spring rod, drives the power distribution network cable placed on it to rotate. Subsequently, the microwave device is started, and the circular disc drives the power distribution network cable to rotate, thereby achieving an all-around ice-melting effect. After the ice melts into water, it flows into the water collection tank at the top of the water collection plate, guided by the annular inclined plate and the fixed rod, and influenced by gravity.

Description

Technical Field

[0001] This invention relates to the field of power distribution network cables, and more specifically to a microwave de-icing and water collection device for power distribution network cables. Background Technology

[0002] In the operation of power distribution networks, cables, as the key carriers of power transmission, are crucial for stable operation. However, in cold climates, cable surfaces are prone to icing, posing numerous hidden dangers to the normal operation of the power distribution network. Ice not only increases the weight of cables, potentially leading to serious accidents such as cable breakage and tower tilting, but also affects the heat dissipation performance of cables, reduces power transmission efficiency, and can even cause short-circuit faults, significantly impacting people's lives and work.

[0003] Traditional methods for de-icing cables in power distribution networks have many drawbacks. Early manual de-icing methods were not only inefficient and labor-intensive, but also required workers to operate in harsh environments, posing significant safety risks. With technological advancements, some heating de-icing devices have emerged, but most of these devices suffer from poor de-icing effects. For example, some heating devices can only heat a localized area of ​​the cable, failing to achieve comprehensive de-icing, resulting in incomplete de-icing and affecting the normal operation of the cables.

[0004] The handling of water generated during the ice-melting process is also a challenge. Traditional ice-melting devices lack effective water collection measures, and the water produced often flows freely, potentially damaging surrounding equipment, such as causing short circuits and corrosion. Moreover, the accumulation of large amounts of water vapor inside the device can cause corrosion and rust on internal components over time, shortening the equipment's lifespan and increasing maintenance costs.

[0005] Furthermore, with the continuous expansion of power distribution networks and the increasing demand for electricity, the requirements for cable de-icing equipment are also becoming more stringent. Traditional de-icing and water collection methods can no longer meet the needs of modern power distribution networks for rapid, efficient, and safe operation. Developing a device capable of efficient microwave de-icing with excellent water collection capabilities is urgently needed. This device can effectively solve the problems of traditional de-icing methods, improve de-icing efficiency, ensure the safe and stable operation of cables, reduce the impact of de-icing issues on the power distribution network, and meet the stringent requirements of modern society for the reliability of power supply. Summary of the Invention

[0006] To solve the above-mentioned technical problems, the present invention provides a microwave de-icing and water collection device for power distribution network cables, comprising:

[0007] A water collection plate, which is circular in shape, has a circular water collection trough at the top, and a bracket is fixedly connected to the bottom of the inner wall of the water collection trough. An annular inclined plate is provided directly above the water collection plate, and the water collection plate and the annular inclined plate are connected by a bracket.

[0008] A melting refrigerator, which is ring-shaped and fixedly connected to the top of a ring-shaped inclined plate, has a cover plate on the top and a cylindrical groove on the top. A microwave device is provided on the inner surface of the melting refrigerator, and a support assembly is provided on the inner side of the melting refrigerator.

[0009] The support rod is cylindrical in shape and is fixedly connected to the bottom of the water collection plate. A fixing plate is fixedly connected to the bottom of the support rod, and a motor is fixedly connected to the central axis at the top of the fixing plate.

[0010] Furthermore, the interior of the melting refrigerator includes a fixed rod, a connecting block, a support rod, a spring rod, and an arc-shaped plate. The fixed rod is positioned directly below the supporting assembly, with its bottom penetrating the annular inclined plate and extending to the outside. The bottom of the fixed rod is connected to the motor output end. The connecting block is fixedly connected to the outer surface of the fixed rod, and the support rod is fixedly connected to the outer surface of the connecting block. The connecting block and the motor are rotatably connected via the fixed rod. The spring rod is fixedly connected to the top of the support rod, and an arc-shaped plate is fixedly connected to the top of the spring rod. The arc-shaped plate is fixedly connected to the inner wall of the melting refrigerator.

[0011] Furthermore, the cover plate includes an insert rod, an annular block, an arc-shaped circular plate, and an annular plate. The insert rod is fixedly connected to the bottom of the cover plate, and the shape and size of the insert rod are the same as the shape and size of the cylindrical groove. The annular block is fixedly connected to the bottom of the cover plate, and the arc-shaped circular plate is fixedly connected to the inner side of the annular block. The top of the arc-shaped circular plate has a circular opening, and the annular plate is fixedly installed at the bottom of the arc-shaped circular plate. The outer surfaces of the arc-shaped circular plate and the annular plate are in contact with the upper end of the inner wall of the refrigerator.

[0012] Furthermore, the supporting assembly includes a circular disc, a force-bearing plate, a first top block, a second top block, and a limiting plate. The top of the circular disc is provided with a hollow groove. The circular disc is rotatably connected to the connecting block via a spring rod and a support rod. The hollow groove is arc-shaped. An air groove is provided inside the circular disc. The bottom of the circular disc is fixedly connected to the top of the arc plate, and the position of the arc plate corresponds to the position of the air groove. The force-bearing plate is located at the central axis inside the air groove. The force-bearing plate is slidably connected to the inner side of the limiting plate. The first top block is fixedly connected to the top of the force-bearing plate. The top of the first top block penetrates the air groove and extends to the outside. A spring is provided inside the air groove. The force-bearing plate and the air groove are connected by the spring. The second top block is fixedly connected to the top of the first top block. The outer surface of the second top block is in contact with the inner wall of the refrigerator. The tops of both the first and second top blocks are arc-shaped. The limiting plate is located on the left and right sides of the force-bearing plate. The bottom of the limiting plate is fixedly connected to the inner wall of the air groove.

[0013] The present invention has the following beneficial effects:

[0014] This invention utilizes a melting refrigerator. When the power distribution network cable is placed on a circular disc, the increased weight of the disc causes the spring rod to move downwards, supporting the weight and improving stability during rotation. Then, the motor is started, causing the fixed rod to rotate and, through the connecting block, move the support rod. The low rotation speed prevents the power distribution network cable from shifting due to centrifugal force. The circular disc, under the influence of the spring rod, rotates the power distribution network cable placed on it. Subsequently, the microwave device is activated, using the circular disc to rotate the power distribution network cable, achieving a comprehensive ice-melting effect and significantly improving the melting efficiency. After the ice melts into water, it flows into the water collection tank at the top of the collection plate, guided by the annular inclined plate, the fixed rod, and gravity.

[0015] This invention utilizes a supporting component. When the circular disc rotates, the second top block located outside it contacts the arc-shaped plate when it moves to a specific position. However, because the position of the arc-shaped plate is fixed, the second top block is affected by a reaction force, causing the first top block and the force-bearing plate to move into the air groove. The limiting plate effectively restricts the position of the force-bearing plate, thereby increasing its stability during movement. The force-bearing plate compresses the spring during movement. When the second top block is no longer in contact with the arc-shaped plate, its arc-shaped top angle allows it to better contact the arc-shaped plate. Under the influence of the spring's elasticity, the second top block impacts the inner wall of the melting refrigerator. The vibration generated during this impact shakes water droplets adhering to the melting refrigerator and the annular inclined plate off or moves them downwards, improving water collection efficiency.

[0016] This invention uses a cover plate. After the power distribution network cable is placed, the cover plate is placed back on top of the ice-melting refrigerator. When the ice melts inside the refrigerator, water vapor will appear. As the water vapor moves upward, some of it will come into contact with the arc-shaped circular plate and continue to evaporate upward through the circular opening. However, because the top is blocked by the cover plate, the water vapor will remain between the arc-shaped circular plate and the cover plate. Over time, it will slowly deform into water and then be affected by the special mechanism of the arc-shaped circular plate, thus remaining on the top of the arc-shaped circular plate. Another part of the water vapor will come into contact with the annular plate and enter the top of the arc-shaped circular plate through the annular plate, which improves the collection effect of the melted water. The insertion rod can greatly improve the connection between the cover plate and the ice-melting refrigerator and also prevent the cover plate from shaking.

[0017] The present invention provides excellent support for the water collection plate and the refrigeration refrigerator located on top of it through the support rod, and also protects the motor to a certain extent. The bracket, with its triangular arrangement, allows the refrigeration refrigerator to stand very stably on top of the water collection plate. Attached Figure Description

The embodiments of the present invention are given for illustrative and descriptive purposes only, and are not intended to be exhaustive or to limit the invention to the forms disclosed. Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described to better illustrate the principles and practical application of the invention, and to enable those skilled in the art to understand the invention and design various embodiments with various modifications suitable for a particular purpose. Example

[0026] Please see Figures 1-4 This invention relates to a microwave de-icing and water collection device for power distribution network cables, comprising:

[0027] Water collection plate 1, the water collection plate 1 is circular in shape, the top of the water collection plate 1 is provided with a circular water collection groove, the bottom of the inner wall of the water collection groove is fixedly connected with a bracket 2, the water collection plate 1 is provided with an annular inclined plate 3 directly above the water collection plate 1, the water collection plate 1 and the annular inclined plate 3 are connected by the bracket 2, and the refrigerator 4 can stand very stably on the top of the water collection plate 1 by means of the bracket 2 and its triangular arrangement.

[0028] The melting refrigerator 4 is ring-shaped and is fixedly connected to the top of the ring inclined plate 3. The top of the melting refrigerator 4 is provided with a cover plate 5. The inner surface of the melting refrigerator 4 is provided with a microwave device 41, and the inner side of the melting refrigerator 4 is provided with a support component 47.

[0029] Support rod 11, which is cylindrical in shape, is fixedly connected to the bottom of water collection plate 1. A fixing plate 12 is fixedly connected to the bottom of support rod 11. Support rod 11 can provide excellent fixed support for water collection plate 1 and the refrigeration refrigerator 4 located on top of it, and can also protect motor 13 within a certain range. Motor 13 is fixedly connected to the central axis at the top of fixing plate 12.

[0030] The interior of the ice-melting refrigerator 4 includes a fixed rod 42, a connecting block 43, a support rod 44, a spring rod 45, and an arc-shaped plate 48. The fixed rod 42 is located directly below the supporting assembly 47. The connecting block 43 is fixedly connected to the outer surface of the fixed rod 42. The support rod 44 is fixedly connected to the outer surface of the connecting block 43. The spring rod 45 is fixedly connected to the top of the support rod 44. The arc-shaped plate 48 is fixedly connected to the inner wall of the ice-melting refrigerator 4. At this time, the circular disk 471, under the influence of the spring rod 45, drives the power distribution network cable placed above it to rotate. Then, the microwave device 41 is started, and the circular disk 471 drives the power distribution network cable to rotate, thereby achieving an all-round ice-melting effect and greatly improving the ice-melting effect. After the ice melts into water, it will flow into the water collection tank at the top of the water collection plate 1 by the guidance of the annular inclined plate 3 and the fixed rod 42 and the influence of gravity.

[0031] The bottom of the fixing rod 42 passes through the annular inclined plate 3 and extends to the outside, and the bottom of the fixing rod 42 is connected to the output end of the motor 13. The connecting block 43 is rotatably connected to the motor 13 through the fixing rod 42.

[0032] The top of the refrigeration refrigerator 4 is provided with a cylindrical groove, and the top of the spring rod 45 is fixedly connected with an arc plate.

[0033] The cover plate 5 includes a rod 51, an annular block 52, an arc-shaped circular plate 53, and an annular plate 54. The rod 51 is fixedly connected to the bottom of the cover plate 5, the annular block 52 is fixedly connected to the bottom of the cover plate 5, the arc-shaped circular plate 53 is fixedly connected to the inner side of the annular block 52, and the annular plate 54 is fixedly installed at the bottom of the arc-shaped circular plate 53. When the ice inside the refrigerator 4 begins to melt, water vapor will appear inside the cover plate 5. When the water vapor moves upward, some of it will come into contact with the arc-shaped circular plate 53 and continue to evaporate upward through the circular opening. However, because the top is blocked by the cover plate 5, the water vapor will be stored between the arc-shaped circular plate 53 and the cover plate 5. It will slowly deform into water over time and then be stored at the top of the arc-shaped circular plate 53 due to the special mechanism of the arc-shaped circular plate 53. Another part of the water vapor will come into contact with the annular plate 54 and enter the top of the arc-shaped circular plate 53 through the guidance of the annular plate 54, which improves the effect of collecting the melted water.

[0034] The shape and size of the insertion rod 51 are the same as those of the cylindrical groove. The top of the arc-shaped circular plate 53 has a circular opening. Through the insertion rod 51, the connection effect between the cover plate 5 and the refrigerator 4 can be greatly improved, and the cover plate 5 can be prevented from shaking.

[0035] The outer surfaces of the arc-shaped circular plate 53 and the annular plate 54 are in contact with the upper end of the inner wall of the melting refrigerator 4. Example

[0036] Please see Figures 1-5 This invention relates to a microwave de-icing and water collection device for power distribution network cables, comprising:

[0037] Water collection plate 1, the water collection plate 1 is circular in shape, the top of the water collection plate 1 is provided with a circular water collection groove, the bottom of the inner wall of the water collection groove is fixedly connected with a bracket 2, and an annular inclined plate 3 is provided directly above the water collection plate 1. The water collection plate 1 and the annular inclined plate 3 are connected by the bracket 2.

[0038] The melting refrigerator 4 is ring-shaped and is fixedly connected to the top of the ring inclined plate 3. The top of the melting refrigerator 4 is provided with a cover plate 5. The inner surface of the melting refrigerator 4 is provided with a microwave device 41, and the inner side of the melting refrigerator 4 is provided with a support component 47.

[0039] Support rod 11, which is cylindrical in shape, is fixedly connected to the bottom of water collection plate 1. A fixing plate 12 is fixedly connected to the bottom of support rod 11, and a motor 13 is fixedly connected to the central axis of the top of fixing plate 12.

[0040] The melting refrigerator 4 includes a fixed rod 42, a connecting block 43, a support rod 44, a spring rod 45, and an arc plate 48. The fixed rod 42 is located directly below the supporting assembly 47. The connecting block 43 is fixedly connected to the outer surface of the fixed rod 42, the support rod 44 is fixedly connected to the outer surface of the connecting block 43, the spring rod 45 is fixedly connected to the top of the support rod 44, and the arc plate 48 is fixedly connected to the inner wall of the melting refrigerator 4. When the power distribution network cable is placed on the circular disc 471 through the melting refrigerator 4, the spring rod 45 moves downward due to the increased weight of the circular disc 471. The spring rod 45 supports the weight, thereby improving the stability during rotation. Then, the motor 13 is started, and the fixed rod 42 begins to rotate under the influence of the motor 13. It moves together with the support rod 44 by relying on the connecting block 43. The rotation speed is low, so the power distribution network cable will not be affected by centrifugal force and thus will not experience positional displacement.

[0041] The bottom of the fixing rod 42 passes through the annular inclined plate 3 and extends to the outside, and the bottom of the fixing rod 42 is connected to the output end of the motor 13. The connecting block 43 is rotatably connected to the motor 13 through the fixing rod 42.

[0042] The top of the refrigeration refrigerator 4 is provided with a cylindrical groove, and the top of the spring rod 45 is fixedly connected with an arc plate.

[0043] The cover plate 5 includes a rod 51, an annular block 52, an arc-shaped circular plate 53, and an annular plate 54. The rod 51 is fixedly connected to the bottom of the cover plate 5, the annular block 52 is fixedly connected to the bottom of the cover plate 5, the arc-shaped circular plate 53 is fixedly connected to the inner side of the annular block 52, and the annular plate 54 is fixedly installed at the bottom of the arc-shaped circular plate 53.

[0044] The shape and size of the insertion rod 51 are the same as those of the cylindrical groove, and the top of the arc-shaped circular plate 53 has a circular opening;

[0045] The outer surfaces of the arc-shaped circular plate 53 and the annular plate 54 are in contact with the upper end of the inner wall of the melting refrigerator 4.

[0046] The supporting assembly 47 includes a circular disk 471, a force-bearing plate 472, a first top block 473, a second top block 474, and a limiting plate 475. The circular disk 471 has an arc-shaped perforated groove on its top and an air groove inside. The force-bearing plate 472 is positioned at the central axis inside the air groove. The first top block 473 is fixedly connected to the top of the force-bearing plate 472, with its top end penetrating the air groove and extending to the outside. The second top block 474 is fixedly connected to the top of the first top block 473. The limiting plate 475 is positioned on the force-bearing plate 472. The second top block 474, located outside the circular disk 471, will contact the arc plate 48 when it moves to a specific position. However, since the position of the arc plate 48 is fixed, the second top block 474 will be affected by the reaction force, which will drive the first top block 473 and the force plate 472 to move into the air groove. Under the influence of the spring force, the second top block 474 will strike the inner wall of the melting refrigerator 4. The vibration generated during the strike will shake the water droplets attached to the melting refrigerator 4 and the annular inclined plate 3 off or make them move downward, thereby improving the water collection efficiency.

[0047] The bottom of the limiting plate 475 is fixedly connected to the inner wall of the air groove, and the force plate 472 is slidably connected to the inner side of the limiting plate 475. The limiting plate 475 achieves the function of limiting the position of the force plate 472, thereby indirectly increasing the stability of the force plate 472 when moving. The force plate 472 will compress the spring when moving.

[0048] A spring is installed inside the air trough, and the force plate 472 is connected to the air trough through the spring. The tops of the first top block 473 and the second top block 474 are both arc-shaped. The outer surface of the second top block 474 is in contact with the inner wall of the refrigerator 4. Through the arc angle of its top, the second top block 474 can better contact the arc plate 48.

[0049] The bottom of the circular disk 471 is fixedly connected to the top of the arc plate, and the position of the arc plate corresponds to the position of the air groove. The circular disk 471 is rotatably connected to the connecting block 43 through the spring rod 45, the support rod 44, and the connecting block 43.

[0050] A specific application of this embodiment is as follows: When it is necessary to melt the power distribution network cable, the cover plate 5 is pulled out from directly above the defrosting refrigerator 4, and the power distribution network cable to be melted is placed on the circular disc 471. Because the weight of the circular disc 471 increases, the spring rod 45 moves downward under the force. Then, the motor 13 is started, and the fixed rod 42 starts to rotate under the influence of the motor 13. It also moves along with the support rod 44 by relying on the connecting block 43. The rotation speed is low, so the power distribution network cable will not be affected by centrifugal force and thus will not shift its position. At this time, the circular disc 471 drives the power distribution network cable placed on it to rotate under the influence of the spring rod 45. Then, the microwave device 41 is started, and the power distribution network cable is driven to rotate by the circular disc 471, thereby achieving the effect of all-round ice melting. When the circular disc 471 rotates, the second top block 474 located outside it will contact the arc plate 48 when it moves to a specific position. However, because the position of the arc plate 48 is fixed, the second top block 474 will be affected by the reaction force and drive the first top block 474. 73 and the force plate 472 move into the air slot. As the force plate 472 moves, it compresses the spring. When the second top block 474 is no longer in contact with the arc plate 48, under the influence of the spring's elasticity, the second top block 474 will strike the inner wall of the melting refrigerator 4. The vibration generated during the strike will shake off or move downwards the water droplets adhering to the melting refrigerator 4 and the annular inclined plate 3, improving the water collection efficiency. After the power distribution network cable is placed, the cover plate 5 is replaced on top of the melting refrigerator 4. When the interior of the melting refrigerator 4... When the ice begins to melt, water vapor will appear inside. As the water vapor moves upward, some of it will come into contact with the arc-shaped circular plate 53 and continue to evaporate upward through the circular opening. However, because the top is blocked by the cover plate 5, the water vapor will remain between the arc-shaped circular plate 53 and the cover plate 5. Over time, it will affect the slowly deformed water and then be stored on the top of the arc-shaped circular plate 53 due to the special mechanism of the arc-shaped circular plate 53. Another part of the water vapor will come into contact with the annular plate 54 and enter the top of the arc-shaped circular plate 53 through the guidance of the annular plate 54, which improves the effect of collecting the melted water.

All other embodiments obtained by those skilled in the art and related fields based on the embodiments of the present invention without inventive effort should fall within the scope of protection of the present invention.
