Description

Technical Field

[0001] The invention relates to the field of insulator ice melting, in particular to a method for melting ice by utilizing a portable iron tower insulator ice melting device. Background Art

[0002] Insulators on towers used to connect cables are prone to accumulation of ice and snow to form icicles in winter or in areas with heavy rain and snow. The presence of icicles will reduce the insulation effect of insulators. When there are too many icicles, the melted water will be mixed with impurities on the surface of the insulator to form conductors, and increase the conductivity of the melted water or the water film on the ice surface, causing distortion of the voltage distribution of the insulator string, thereby reducing the flashover voltage of the ice-covered insulator string, and ice flash is very likely to occur. For horizontal insulator strings, when there is less ice, the downward flow of ice water after the ice melts will not pose a major threat. However, when the ice is not cleaned for a long time and the amount of ice increases, ice bridging will form, which will greatly reduce the insulation strength of the insulator and greatly increase the possibility of ice flash. Therefore, it is necessary to clean the ice on the insulators in time to avoid power outages caused by thickening of the ice layer. The existing methods for cleaning the ice on the insulators include knocking or melting. The knocking method is simple, but it is easy to damage the insulators, especially the porcelain insulators, during the knocking process, affecting the insulating effect of the insulators. The melting method generally uses an external heating element to melt the ice on the insulators. The existing ice melting structure has a relatively complex main body and is very inconvenient to carry. It is difficult to achieve single-person climbing and carrying when cleaning the ice on the insulators high up on the tower. The cleaning efficiency is very low, and it is necessary to perform long-term operations on the insulators high up on the tower, which increases the time of aerial operations and increases the potential safety risks of construction. Summary of the invention

[0003] The purpose of the present invention is to provide a method for melting ice using a portable iron tower insulator ice melting device, which has a simple structure and is convenient to carry when climbing an iron tower, thereby achieving automatic and efficient ice melting of high-altitude insulators and reducing the time and potential safety risks of aerial operations.

[0031] The present invention will be further described below in conjunction with specific embodiments. It should be understood that these embodiments are only used to illustrate the present invention and are not intended to limit the scope of the present invention. In addition, it should be understood that after reading the content taught by the present invention, those skilled in the art can make various changes or modifications to the present invention, and these equivalent forms fall within the scope limited by the application equally.

[0032] The present invention discloses a method for melting ice by using a portable iron tower insulator ice melting device. The portable iron tower insulator ice melting device comprises an ice melting body, which is a main component of ice melting treatment. The ice melting body comprises two symmetrically arranged brackets 1, which play a supporting role. The brackets 1 are provided with shoulder straps 2, and the ice melting components are arranged on the brackets 1. When it is necessary to melt ice on an insulator at a high place, the shoulder straps 2 are used to carry the ice melting body composed of the brackets 1 on the back of the operator, so as to facilitate climbing the iron tower to a high place, making the device more convenient to carry. The two brackets 1 are detachably connected by a screw rod 3. Specifically, the two brackets 1 can be connected by The screw rod 3 is fixed and separated, and a nut is set at the end of the screw rod 3. The screw rod 3 passes through one bracket 1 and is threadedly connected with the other bracket 1 to realize the rapid disassembly and matching of the two brackets 1. The bracket 1 is provided with a notch 4, and the notch 4 is set on the opposite side of the two brackets 1. After the two brackets 1 are combined together by using the screw rod 3, the insulator 5 can pass through the through hole 6 formed by the two notches 4, that is, the two brackets 1 can be sleeved on the outside of the insulator 5 after being split, so as to realize the matching of the ice melting body 1 and the insulator 5. It also includes two symmetrically arranged end plates 7, one of which is detachably connected to the iron tower 8 at one end of the insulator 5, and the other end plate 7 is detachably connected to the insulator 5. The two ends of the slide bar 9 are detachably connected to the end plates 7, and the two ends of the slide bar 9 are detachably connected to the end plates 7. The two sides of the ice-melting body are slidably connected to the two slide bars 9. After the end plates 7 are fixed to the two ends of the insulator 5, the slide bar 9 is slidably connected to the ice-melting body to achieve sliding cooperation between the two. Then, the two ends of the slide bar 9 are cooperatively connected to the end plates 7 on both sides to achieve stable support for the slide bar 9. Such a structure can make the ice-melting body be sleeved on the outside of the insulator 5 for ice melting, and the ice melting at the current position can be completed. Sliding along the slide bar 9, the ice-melting operation of other positions of the insulator 5 is gradually realized, and the efficiency of ice-melting is ensured. The bracket 1 is rotatably connected with a power wheel 10, which is driven to rotate by a motor. The power of the motor can be provided by a battery carried by the bracket 1. The power wheel 10 is in rolling contact with the slide bar 9. After the slide bar 9 is connected with the ice-melting body, the ice-melting body can automatically slide on the slide bar 9 through the rotation of the power wheel 10. After the assembly is completed, the ice-melting body can automatically melt ice along the slide bar 9. The operator only needs to complete the installation steps, and the operation time on the insulator 5 is greatly shortened, ensuring the safety of the ice-melting operation.

[0033] The slide bar 9 includes a plurality of support rods 11 connected end to end, and the support rods 11 are a plurality of rod-shaped structures of the same size. Adjacent support rods 11 can be detachably connected. The plurality of support rods 11 can be used to form a longer slide bar 9 to provide guidance and support for the sliding of the ice melting body. After use, the plurality of support rods 11 can be disassembled to reduce the range of coverage of their size, which is convenient for operators to carry. A storage plate 12 is welded or bolted on the bracket 1. The disassembled support rods 11 are arranged in parallel through the storage plate 12 on one side and can be detachably connected to the storage plate 12 on the other side. Such an arrangement allows the disassembled single support rod 11 to be arranged in parallel between the storage plates 12 on the two brackets 1, so that after the plurality of support rods 11 are stored on the bracket 1, the space occupied is greatly reduced, which is more convenient to carry. Specifically, a circular hole is provided on one storage plate 12, and the support rod 11 can be detachably connected to the other storage plate 12 after passing through the circular hole. , realize the fast and stable storage of the support rod 11, the two end plates 7 can be detachably connected to the storage plate 12 after being disassembled, so that the end plates 7 can also be stored and connected to the storage plate 12, so that the overall structure of the device is more compact after storage, reducing the space occupancy rate and being more convenient to carry. The inner side of the notch 4 is provided with a plurality of electric heating tubes 13, and the electric heating tubes 13 can be powered by the battery carried on the bracket 1. The inner side of the notch 4 is provided with an ice melting plate 14 in contact with the electric heating tube 13. The ice melting plate 14 is a heat conducting component, preferably made of metal, so that the heat generated by the electric heating tube 13 is more evenly distributed to the ice melting plate 14 in contact with it. The two ice melting plates 14 are integrally sleeved on the outer side of the insulator 5. Such a structure makes the heat distribution at various positions on the outer side of the insulator 5 more even. When melting ice, the degree of melting at various positions is consistent, which improves the effect of melting ice, does not require secondary rework or multiple melting, and ensures the high efficiency of ice melting construction;

[0034] The method of melting ice includes the following steps:

[0035] 1) The operator uses the shoulder strap 2 to carry the ice-melting body and climbs along the iron tower 8 to the position of the insulator 5. At this time, the multiple disassembled support rods 11 and the end plates 7 are connected to the ice-melting body composed of the two brackets 1. The overall structure is more compact, which is convenient for the operator to climb on the iron tower directly on his back, making the use of the device more flexible and the use scenarios more diverse. The multiple support rods 11 are removed from the storage plate 12 of the bracket 1, and then connected end to end to form two slide rods 9. The length of the slide rod 9 is preferably enough to cover the length of the insulator 5, which is generally more than two meters. The number and length of the specific support rods 11 can be set according to the needs of use. Generally, the length of the support rod 11 does not exceed the width of the operator's back. The two slide rods 9 are passed through the two sides of the ice-melting body to achieve sliding cooperation with it, and the slide rods 9 on the upper and lower sides are used to provide support and guidance for the ice-melting body. The slide rod 9 is arranged parallel to the insulator 5 to ensure that the ice-melting body can perform gradual ice-melting operations along the length direction of the insulator 5.

[0036] 2) Remove the two end plates 7 from the storage plate 12, and connect one of the end plates 7 to the iron tower 8 at one end of the insulator 5. The specific connection method is not limited, and magnetic attraction or bolt fixing can be used. The operator holds the other end plate 7 over the insulator 5 and connects the other end plate 7 to the end of the insulator 5 away from the iron tower 8. This process and the subsequent removal of the end plate 7 are the time for the operator to work on the insulator 5. This period of time is very short. The operator can perform other operations or stand in a safe position on the iron tower to wait for the ice to melt. The intensity of the operation is high. The safety is effectively guaranteed. The two brackets 1 are opened by rotating the screw rod 3 to separate the two brackets 1, so that the two brackets 1 can be conveniently sleeved on the outside of the insulator 5. After the two brackets 1 are sleeved on the outside of the insulator 5, they are fixed with the screw rod 3. After the ice melting is completed, the ice melting body composed of the brackets 1 can be separated from the insulator 5 by reverse operation, so that the through hole 6 composed of the notches 4 on the two brackets 1 is sleeved on the outside of the insulator 5. The size of the through hole 6 composed of the two notches 4 is larger than the cross-sectional size of the insulator 5, so as to avoid being too close to the insulator 5 and causing damage to the insulator 5.

[0037] 3) Connect the ends of the two slide bars 9 to the two end plates 7 respectively to support the two slide bars 9, and use the rotation of the power wheel 10 in rolling contact with the slide bars 9 to start the motor. The remote switch can be used to control the opening and closing of the motor to drive the ice-melting body to slide along the slide bars 9, so that the ice-melting body moves outside the insulator 5. The end plates 7 and the slide bars 9 form a sliding support for the ice-melting body to ensure the gradual ice-melting operation at various positions of the insulator 5.

[0038] 4) The electric heating tube 13 in the notch 4 on the bracket 1 generates heat, that is, the switch of the electric heating tube 13 is turned on to generate heat, and the heat is transferred to the contacting ice melting plate 14. The setting of the ice melting plate 14 can make the heat generated by the multiple electric heating tubes 13 more evenly distributed at various positions, so that the degree of ice melting at various positions of the longitudinal section of the insulator 5 is consistent, and there is no need to rework or multiple ice melting operations, so as to ensure the ice melting effect. The two heated ice melting plates 14 are integrally sleeved on the outside of the insulator 5 to melt the ice accumulated on the insulator 5. As the ice melting body slides, the ice at various positions of the insulator 5 is gradually melted. Such a setting reduces the working time on the insulator 5, and the device is more convenient to carry to a high place for use. The installation after disassembly is also very convenient and quick, ensuring the efficiency and safety of ice melting.

[0039] Preferably, adjacent support rods 11, support rods 11 and storage plates 12, and support rods 11 at the ends and end plates 7 are all detachably connected via threads. Specifically, a threaded head is provided at the end of the support rod 11, and a threaded hole is provided at the other end. Correspondingly, threaded holes are provided on one end plate 7 and the storage plate 12, and a threaded hole is provided on the other end plate. When in use, the threaded head of one support rod 11 is rotatably connected to the end of another support rod 11 or the threaded hole of another end plate or the storage plate 12, so as to realize rapid installation and storage of the support rod 11. The structure is simple and stable, and disassembly and assembly are more convenient.

[0040] Preferably, the length of the support rod 11 is not greater than the distance between the storage plates 12 on the two brackets 1. Such an arrangement ensures that after the support rod 11 is disassembled and connected to the storage plate 12, the other end of the support rod 11 will not extend to the outside of the storage plate 12 on the other side, so that the structure of the support rod 11 after storage is located within the range of the storage plates 12 on the two brackets 1. When climbing and moving with the ice-melting body on the back, it is not easy for the support rod 11 to interfere with other parts of the iron tower 8, thereby ensuring the convenience of carrying.

[0041] Preferably, both of the end plates 7 are provided with a clamping hole 15 used to cooperate with the end of the insulator 5, and the clamping hole 15 passes through one side of the end plate 7. When the end plate 7 is installed, the clamping hole 15 passes through the connecting cable at the end of the insulator 5 and is clamped on the connecting cable to support the end plate 7. The end plate 7 connected to the iron tower 8 is provided with a magnetic buckle 16, and the magnetic buckle 16 is attracted to the iron tower 8. This connection method does not limit the connection position of the end plate 7 and the iron tower 8, so that the end plate 7 can be magnetically fixed to the position of the iron tower 8 of any shape through the magnetic buckle 16, thereby ensuring the convenience of the end plate 7 and the iron tower 8.

[0042] Preferably, the magnetic buckle 16 is an inverted L-shape, and a clamping rod 17 is threadedly connected to the vertical part of the magnetic buckle 16. The clamping rod 17 passes through the magnetic buckle 16 and contacts the iron tower 8. After the magnetic buckle 16 and the iron tower 8 are attracted and fixed, the clamping rod 17 is rotated so that its end rotates forward and contacts the iron tower 8, thereby further fixing the end plate 7 and improving the stability of the support structure composed of the end plate 7 and the sliding rod 9.

[0043] Preferably, the ice melting plate 14 is arc-shaped, and the arc-shaped structure can maintain the same distance from each position outside the insulator 5 to ensure the uniformity of ice melting at each position. The ice melting plate 14 is high in the middle and low on both sides. The storage plate 12 on the lower bracket 1 is tilted downward on one side. With this arrangement, the ice water generated by ice melting can slide down from both sides of the ice melting plate 14 and is not easy to gather on the ice melting plate 14. The setting of the ice melting plate 14 also provides good protection for the electric heating tube 13 to avoid direct contact with the melted ice water. At the same time, the flowing ice water can also slide along the tilted storage plate 12 when it flows to the storage plate 12, effectively preventing the melted ice water from gathering on the structure of the ice melting body to prevent damage to the internal heating elements, etc., thereby ensuring the service life of the device.

[0044] Preferably, a fixing block 18 is welded or bolted on the bracket 1, and a through hole 19 is provided on the fixing block 18. The slide bar 9 passes through the through hole 19 and is slidably connected thereto, so that the sliding cooperation between the slide bar 9 and the bracket 1 is more convenient and accurate. A U-shaped groove 20 is provided on one side of the fixing block 18, and the power wheel 10 is slidably connected in the U-shaped groove 20. Such an arrangement allows the power wheel 10 to slide outward when installing the slide bar 9, so that it provides space for the installation of the slide bar 9, making the installation smoother. After the installation is completed, the power wheel 10 is slid in the opposite direction so that the power wheel 10 contacts the slide bar 9, thereby ensuring the sliding of the ice melting body along the slide bar 9, making the installation of the device smoother, and the installation is more efficient and convenient.

[0045] Preferably, a frame 21 is slidably connected in the U-shaped groove 20, and the frame 21 is preferably U-shaped. The power wheel 10 is rotatably connected to both sides of the U-shape in the frame 21, and the sliding of the frame 21 is used to drive the movement of the power wheel 10. Slide blocks 22 are symmetrically welded or integrally formed on both sides of the frame 21. Slide blocks 23 are symmetrically arranged on both sides of the U-shaped groove 20. The slide blocks 23 penetrate the side walls of the U-shaped groove 20. The output shaft of the motor driving the power wheel 10 to rotate passes through the slide block 22 and is connected to the power wheel 10. The slide block 22 is slidably connected in the slide block 23. A return spring 24 is arranged between the slide block 22 and the slide block 23. The U-shaped groove 20 is threadedly connected to the slide block 23. There is an adjusting rod 25, one end of which passes through the U-shaped groove 20 and contacts the frame 21. When the power wheel 10 is slidably moved, the adjusting rod 25 is rotated so that its end contacts the frame 21, and then the frame 21 and the power wheel 10 are pushed toward the slide bar 9 to achieve contact between the power wheel 10 and the slide bar 9. At this time, the return spring 24 is in a compressed state. When the slide bar 9 needs to be installed, the adjusting rod 25 is rotated in the opposite direction to make the power wheel 10 automatically slide in the direction away from the slide bar 9 under the action of the return spring 24. In addition, the power wheel 10 can be kept in a position away from the slide bar 9 under the action of the return spring 24 under normal conditions, which facilitates the quick installation operation of the slide bar 9.

[0046] Preferably, the support rod 11 is made of hollow metal material, which reduces the weight of the support rod 11 while ensuring the supporting strength, making it more labor-saving to carry the device when climbing a tower. The shoulder strap 2 is an elastic belt structure. Under normal conditions, the shoulder strap 2 fits on the surface of the bracket 1 under the action of elastic force, avoiding interference with other components and ensuring the smoothness of installation, use and operation of the device.

[0047] Preferably, a limiting groove 26 is provided on the surface of the power wheel 10, and the limiting groove 26 is recessed inward from the surface of the power wheel 10. The slide bar 9 contacts the limiting groove 26. The setting of the limiting groove 26 enables it to maintain a stable relative position with the slide bar 9 when in contact with the slide bar 9, thereby making the contact between the two more firm, thereby ensuring the accuracy of the ice melting body moving along the slide bar 9 when the power wheel 10 rotates.

[0048] Working principle: The structure of the present invention utilizes a plurality of support rods 11 connected end to end to form a slide bar 9 structure. The two ends of the slide bar 9 structure are fixed to the ends of the iron tower 8 and the insulator 5 through two end plates 7. The ice melting body used for melting ice can realize automatic sliding movement along the slide bar 9 under the rolling contact between the power wheel 10 and the slide bar 9. At the same time, the through hole 6 composed of the notches 4 on the two brackets 1 is sleeved on the outside of the insulator 5. When in use, the screw rod 3 is rotated to open the two brackets 1 and then sleeved on the outside of the insulator 5 and fixed with the screw rod 3. An electric heating pipe 13 is arranged in the notch 4. Heat is generated by the ice melting plate 14 in contact with the electric heating pipe 13 to realize the ice melting operation on the insulator 5 in the through hole 6. After installation, the ice melting body can be driven by the power wheel 10 to move along the insulator 5 to realize the automatic ice melting operation, and no operator is required to stay for a long time. The time required to operate on the insulator 5 at a high place is reduced, which reduces the time of aerial work and the potential safety risks of aerial work; after disassembly, multiple support rods 11 can be connected to the storage plate 12 on the bracket 1 in parallel, and the end plates 7 at both ends can also be stored and connected to the storage plate 12. Such a structure allows the whole to form a square ice-melting main structure after storage. The space of the square structure includes the range formed by the bracket 1 and the storage plate 12. The overall structure is more concentrated and occupies less space. When construction workers climb on the iron tower 8, they can use the straps 2 on the bracket 1 to carry them on their backs, and disassemble and install them after climbing to a designated height. A single person can complete the entire carrying and installation process, and the time required to operate on the insulator 5 at a high place is very short, which greatly improves the operating efficiency and safety of ice-melting operations on the insulator 5 at a high place.
