Description

Technical Field

[0001] The invention relates to the technical field of high-altitude line deicing, in particular to a remote-controlled release type overhead line deicing device. Background Art

[0002] In colder areas, overhead lines often freeze. If not cleaned in time, ice will easily form, causing the weight of the lines to increase, breaking the lines and causing power or communication outages, affecting residents' normal lives.

[0003] With the development of science and technology, deicing robots that can realize automatic line deicing are the current mainstream deicing method. They mainly include a walking unit that can walk on the line and a deicing unit installed on the walking unit to realize deicing. Their main structures are recorded in Chinese patent publication No. CN115800166A, entitled A new type of ground wire deicing device and deicing method thereof, and Chinese patent publication No. CN115800164B, entitled A deicing device and deicing method for a ground wire deicing robot for a power transmission line.

[0004] Although the above-mentioned deicing robot can realize deicing while walking on the line, in the actual deicing process, since the line that needs to be deiced is long and it is limited by the endurance of the deicing robot, it often needs to be stopped for charging many times, and the deicing efficiency is low. In addition, on the overhead line, overhead poles are set at intervals, and the deicing robot does not have the ability to cross the poles. Therefore, when encountering poles, it is necessary to stop the deicing robot and move it across the poles to operate again, which further affects the deicing efficiency. At the same time, for some split conductors, multiple spacers are set between the split conductors, and the deicing robot often does not have the ability to cross the spacers, resulting in that such lines can only be deiced manually, and there is a problem of insufficient adaptability of the deicing robot, which needs to be solved urgently.

[0016] As a further solution of the present invention: a rubber sleeve is provided on the outer periphery of the cylindrical seat at the clamping cavity, and a fluorescent sticker is provided on the rubber sleeve.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] 1. The ice-breaking assembly in this application is pre-clamped on the wire through a clamping assembly before the wire is covered with ice. After the wire is covered with ice, the ignition of the ice-breaking assembly on the ice-covered cable is turned on by remote control, and the ice-breaking hammer is fired outward to achieve de-icing. Compared with the traditional de-icing method using a de-icing robot, this application does not need to consider the problem that the de-icing robot cannot cross the poles or spacers, resulting in low de-icing efficiency or inability to de-icing, nor does it have the problem of de-icing efficiency affected by the endurance of the de-icing robot. By pre-clamping multiple ice-breaking assemblies on the wire at intervals, efficient de-icing at multiple stations can be achieved, which has the advantages of high de-icing efficiency and high adaptability to line working conditions.

[0019] 2. There are at least three cylindrical seats, and at least three cylindrical seats are connected end to end through a connecting seat to form a frame structure, and the frame structure forms a clamping cavity clamped on the outer periphery of the wire; the connecting seat includes a fixing part and a latch assembly that plugs and locks the fixing part with the cylindrical seat, and the plug-in part of the latch assembly and the cylindrical seat is connected to the launch cavity, and the high-pressure gas flowing into the launch cavity and the ice-breaking hammer drive the latch assembly to slide outward to disengage the lock, so that the frame structure disintegrates. Through the cooperation of the ice-breaking assembly and the clamping assembly, the disintegration of the clamping assembly can be achieved after the ice-breaking operation of the ice-breaking assembly is completed, reducing the process of removing the clamping assembly and the ice-breaking assembly from the cable.

[0020] 3. The fixing part of the connecting seat is a C-shaped ring, and the inner cavity of the C-shaped ring can be sleeved on the outer circumference of the cylindrical seat. The inner cavity of the C-shaped ring can be used in conjunction with the latch assembly to achieve fixation with the cylindrical seat. The latch assembly includes two T-shaped outer pins distributed on both sides of the C-shaped ring. The T-shaped head of the T-shaped outer pin is elastically driven by an extrusion spring and plugged into the pin hole of the side wall of the cylindrical seat. The pin hole is also provided with a T-shaped push head whose outer end abuts against the head of the T-shaped outer pin and whose inner end extends into the firing chamber. The inner end of the T-shaped push head is located on the firing path of the ice-breaking hammer, and the ice-breaking hammer can cooperate with the inner end of the T-shaped push head. When the high-pressure gas flows to the firing chamber and drives the ice-breaking hammer to fire, the ice-breaking hammer generates a thrust to drive the T-shaped push head to slide outward, and at the same time, part of the high-pressure gas enters the pin hole to assist the T-shaped push head to slide outward, thereby separating the T-shaped outer pin from the cylindrical seat, thereby unlocking the C-shaped ring and the cylindrical seat, and causing the cylindrical seat to disintegrate.

[0021] 4. The outer end of the ice-breaking hammer is of conical structure, and the inner end of the T-shaped push head abuts against the conical surface of the ice-breaking hammer. The conical surface and the T-shaped push head form an oblique wedge fit, and the ice-breaking hammer is elastically locked in the launching chamber before the ice-breaking hammer is launched, thereby preventing the ice-breaking hammer from falling out of the launching chamber when the cylindrical seat is inverted.

[0022] 5. The clamping process of the clamping assembly can be operated by a crane or a drone. The wire deicing and unlocking mechanism during the clamping process can switch the clamping assembly from the initial state to the clamping state, thereby realizing the clamping operation of the clamping assembly on the wire, without the need to climb onto the wire, thereby ensuring the safety of the clamping of the clamping assembly. In addition, among the three cylindrical seats that make up the clamping assembly, the third cylindrical seat slides along its own axis and blocks the opening of the V-shaped structure. Compared with the third cylindrical seat that rotates to block the opening of the V-shaped structure, it not only ensures that the three cylindrical seats can achieve stable fit with the wire, but also ensures that the third cylindrical seat will not loosen when subjected to the radial force generated by the cable; combined with the three cylindrical seats to form a stable triangular frame structure, the stability of the clamping assembly on the wire is effectively guaranteed.

[0023] 6. The unlocking mechanism in the initial state of the lock adopts a labor-saving lever structure formed by the unlocking lever, and in the unlocking process, it is only necessary to separate the limit latch downward from the driving part, which has the advantage of labor-saving unlocking in the initial state.

[0024] 7. When the unlocking lever is rotated to unlock, since the aperture of the connecting socket is larger than the outer diameter of the fulcrum rotating pin, the unlocking lever loses its elastic thrust after being unlocked. At this time, the fulcrum rotating pin slides and separates from the connecting socket, realizing the automatic separation of the unlocking lever and the snap-on assembly, preventing the snap-on assembly from carrying excess structure that affects the ice-breaking effect of the ice-breaking assembly.

[0025] 8. In the elastic drive assembly, the slider can be located at the outer end of the sliding and expanded slide bar in the initial state. When elastically contracted, the slider can slide to the inner end of the slide seat, so that the sliding stroke of the slider is close to the total length of the slide seat and the slide bar. Compared with directly using a multi-stage telescopic rod as the elastic drive assembly, when the space occupancy after contraction is the same, the driving stroke of the elastic drive assembly can be effectively improved.

[0026] 9. A rubber sleeve is provided on the outer periphery of the cylindrical seat at the clamping cavity, which effectively improves the clamping friction between the cylindrical seat and the conductor. In addition, a fluorescent sticker is provided on the rubber sleeve for nighttime inspection and visibility. It can be identified not only manually at night but also through monitoring probes on the transmission line. The fluorescent stickers on conductors of different phases have different colors, which can be used to distinguish conductors of different phases. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0036] 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 described embodiments 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 creative work are within the scope of protection of the present invention.

[0037] For ease of understanding, the specific structure and working mode of the present invention are further described below in conjunction with the accompanying drawings:

[0038] The specific structure of the present invention refers to Figure 1-8 As shown, its main structure includes a clamping assembly that can be clamped on the conductor and an ice-breaking assembly installed on the clamping assembly and used for breaking ice.

[0039] 1. Card-connecting components

[0040] like Figure 1-2 As shown, the clamping assembly includes three cylindrical seats 10, which are respectively a first cylindrical seat 10a, a second cylindrical seat 10b and a third cylindrical seat 10c. The inner ends of the first cylindrical seat 10a and the second cylindrical seat 10b are fixed to each other and combined to form a V-shaped structure. The third cylindrical seat 10c is elastically driven by the elastic drive assembly 20 installed on the first cylindrical seat 10a and can elastically slide along its own axis. The third cylindrical seat 10c has the following characteristics during the elastic sliding process: Figure 1 The initial state of the V-shaped opening is shown, and Figure 2 The clamping state shown is a triangular clamping cavity formed by the first cylindrical seat 10a and the second cylindrical seat 10b.

[0041] like Figure 1As shown, the initial state is locked by the unlocking mechanism 50, and the unlocking mechanism 50 has an operating part located at the opening of the V-shaped structure, and the operating part is driven by the wire abutment entering the opening of the V-shaped structure to unlock the initial state, after which the driving part of the elastic driving component 20 drives the third cylindrical seat 10c to slide to form a clamping state.

[0042] When using, Figure 8 As shown in the A state, the initial state of the clamping assembly can be hoisted by a drone or a crane at the intersection of the V-shaped structure, so that the opening of the V-shaped structure faces downward, and the opening of the V-shaped structure is hoisted to the top of the wire. Thereafter, the V-shaped structure is hoisted downward, and the opening of the V-shaped structure is set on the outer periphery of the wire. Figure 8 As shown in the state B in the figure, when the wire enters the inner side of the opening of the V-shaped structure, the wire pushes the operating part to unlock the initial state, and then, as shown in the figure Figure 8 As shown in the state C, the third cylindrical seat 10c is driven by the driving part of the elastic driving assembly 20 to slide along its own axis. Finally, as shown in FIG. Figure 8 As shown in the state D, the third cylindrical seat 10c, the first cylindrical seat 10a and the second cylindrical seat 10b are enclosed together to form a clamping state of a triangular clamping cavity, thereby completing the clamping and fixing of the clamping assembly on the wire. The clamping process of the clamping assembly can be operated by a crane or a drone, without climbing onto the wire, ensuring the safety of the clamping of the clamping assembly. In addition, among the three cylindrical seats 10 that make up the clamping assembly, the third cylindrical seat 10c slides along its own axis and blocks the opening of the V-shaped structure. Compared with the third cylindrical seat 10c, which uses rotation to block the opening of the V-shaped structure, it not only ensures that the three cylindrical seats 10 can be stably fitted with the wire, but also ensures that the third cylindrical seat 10c will not loosen when subjected to the radial force generated by the cable; combined with the three cylindrical seats enclosed to form a stable triangular frame structure, the stability of the clamping assembly on the wire is effectively guaranteed.

[0043] Specifically, the unlocking mechanism 50 includes a baffle rod (not shown in the figure) located at the opening of the V-shaped structure, and the two ends of the baffle rod are respectively in contact with the third cylindrical seat 10c and the second cylindrical seat 10b to prevent the third cylindrical seat 10c from elastically sliding toward the opening of the V-shaped structure, and the operating part is formed by the rod body of the baffle rod. When the wire enters the inner side of the opening of the V-shaped structure, the contact between the baffle rod and the third cylindrical seat 10c and the second cylindrical seat 10b is loosened, so that the baffle rod falls, thereby releasing the initial state. In this embodiment, the unlocking mechanism 50 can automatically separate from the clamping assembly after the initial state is released, preventing the clamping assembly from carrying redundant structures that affect the ice-breaking effect of the ice-breaking assembly. Since a large thrust is required to push the movement of the baffle rod in this embodiment, it is suitable for a structure with a large gravity of the clamping assembly. In order to adapt to a structure with a small gravity of the clamping assembly, the unlocking mechanism 50 of the present application also provides the following another embodiment.

[0044] like Figure 1 and Figure 4 As shown, the unlocking mechanism 50 includes an unlocking lever 52 that is rotatably engaged with the second cylindrical seat 10b through a fulcrum rotating pin 51, and the fulcrum rotating pin 51 is arranged parallel to the wire; the first end of the unlocking lever 52 is fixed with a limit latch 53 that forms a lock with the drive part to lock the initial state. The second end of the unlocking lever 52 is located at the opening of the V-shaped structure, and the second end of the unlocking lever 52 can be pushed by the wire entering the opening of the V-shaped structure, and the limit latch 53 carried by the unlocking lever 52 rotates to unlock the drive part to unlock the initial state, and the second end of the unlocking lever 52 constitutes the operating part. In this embodiment, the unlocking mechanism 50 adopts a labor-saving lever structure formed by the unlocking lever 52, and in the unlocking process, the limit latch 53 only needs to be separated downward from the drive part, which has the advantage of labor-saving unlocking in the initial state. In specific implementation, the second end of the unlocking mechanism 52 located at the opening of the V-shaped structure is preferably inclined toward the inside of the V-shaped structure, so that the wire can abut against the second end after a partial area has entered the inner cavity of the V-shaped structure. Thereafter, the wire abuts against the second end to trigger the unlocking of the initial state, which can stably ensure that the third cylindrical seat 10c enters the clamping cavity inside the V-shaped structure before sliding along its own axis and sealing the opening of the V-shaped structure.

[0045] Furthermore, to ensure that the unlocking lever 52 does not remain on the clamping assembly after unlocking, Figure 4 As shown, the second cylindrical seat 10b is provided with a connecting socket 10a1 for inserting the fulcrum rotating pin 51, and the aperture of the connecting socket 10a1 is larger than the outer diameter of the fulcrum rotating pin 51. In the initial state, since the unlocking lever 52 is used for locking the driving part, and since the force is mutual, the driving part will also generate an elastic thrust on the unlocking lever 52. Under this elastic thrust, the outer wall of the fulcrum rotating pin 51 abuts against the inner wall of the connecting socket 10a1 to maintain the unlocking lever 52 in the initial locked state without falling. When the unlocking lever 52 rotates to unlock, since the aperture of the connecting socket 10a1 is larger than the outer diameter of the fulcrum rotating pin 51, the unlocked unlocking lever 52 loses the elastic thrust. At this time, the fulcrum rotating pin 51 slides and separates from the connecting socket 10a1, realizing the automatic separation of the unlocking lever 52 and the clamping assembly.

[0046] On the basis of the above, if Figure 3 and Figure 5As shown, the elastic drive assembly 20 includes a slide 21 fixed to the second cylindrical seat 10b, a slide bar 22 slidably fitted on the slide 21, and a slider 23 slidably fitted on the slide bar 22. The slider 23 constitutes a driving part, and a tension spring 24 is installed on the slide 21 to drive the slide 21 to elastically contract into the slide 21. In the initial state, the slider 23 is located at the outer end of the slide bar 22 that is slid and expanded, and the inner end of the slide bar 22 is provided with an abutment portion that can abut against the slider 23 and slide to the inner end of the slide 21 together with the slider 23. In this embodiment, the slider 23 can be located at the outer end of the slide bar 22 that is slid and expanded in the initial state, and when elastically contracted, the slider 23 can slide to the inner end of the slide 21, so that the sliding stroke of the slider 23 is close to the total length of the slide 21 and the slide bar 22. Compared with directly using a multi-stage telescopic rod as the form of the elastic drive assembly 20, when the same space occupancy after contraction is the same, the driving stroke of the elastic drive assembly 20 can be effectively improved. In this embodiment, in order to adapt to the implementation of the unlocking mechanism 50 using the unlocking lever 52 , the outer end of the slide bar 22 has a limiting insertion hole 221 for the limiting pin 53 to be inserted into and lock the slider 23 .

[0047] On the basis of the above, if Figure 1 As shown, a rubber sleeve 40 is provided at the clamping cavity on the outer circumference of the cylindrical seat 10, which effectively improves the clamping friction between the cylindrical seat 10 and the conductor. In addition, a fluorescent sticker 41 is provided on the rubber sleeve 40 for nighttime inspection and visibility. It can be identified not only manually at night but also by monitoring probes on the transmission line. In addition, the fluorescent stickers 41 on conductors of different phases have different colors, which can be used to distinguish conductors of different phases.

[0048] 2. Ice breaking components

[0049] like Figure 6As shown, the ice-breaking assembly mainly includes an ice-breaking hammer 14. Specifically, the end of the cylindrical seat 10 is sequentially provided with a launch chamber 12 and a combustion chamber 13 connected to each other through an air guide hole 111 from the outside to the inside, and a movable sealing assembly is provided in the air guide hole 111. The ice-breaking hammer 14 is distributed in the launch chamber 12 and can be launched outward along the axial direction of the cylindrical seat 10 to remove ice. A combustible material and an igniter 15 opened by remote control are provided in the combustion chamber 13, so that the combustible material in the combustion chamber 13 can be ignited and burned by remote control to generate high-pressure gas, and the high-pressure gas generates an impact force that pushes the ice-breaking hammer 14 to be launched outward. The ice-breaking assembly in the present application is pre-clamped on the wire by a clamping assembly before the wire is covered with ice. After the wire is covered with ice, the igniter 15 of the ice-breaking assembly on the ice-covered cable is opened by remote control, and the ice-breaking hammer 14 is launched outward to achieve deicing. Compared with the traditional method of using de-icing robots for de-icing, the present application does not need to consider the problem of low de-icing efficiency or inability to de-icer due to the inability of the de-icing robot to cross over telephone poles or spacers. There is also no problem of de-icing efficiency being affected by the endurance of the de-icing robot. By pre-interval-connecting multiple ice-breaking components on the conductors, efficient de-icing at multiple stations can be achieved, which has the advantages of high de-icing efficiency and high adaptability to line working conditions.

[0050] In this embodiment, the cylindrical seat 10 can only be used as a carrier of the ice-breaking assembly, and an existing clamping mechanism such as a clip can be provided to clamp the wire. In addition, the cylindrical seat 10 can be provided in at least three pieces, and a frame structure connected end to end can be formed between at least three cylindrical seats 10, and a clamping cavity clamped on the outer periphery of the wire can be formed by the frame structure.

[0051] In addition, if Figure 6 As shown, the movable sealing assembly includes a one-way valve plug 16 distributed in the air guide hole 111 and slidable toward the firing chamber 12, and a sealing ring 17 is arranged on the outer periphery of the one-way valve plug 16 to seal the air guide hole 111, so as to achieve stable sealing of the air guide hole 111. In addition, radial holes 110 are distributed radially along the outer side of the air guide hole 111, and abutting steel columns 18 driven by abutting springs 19 and elastically abutting against the one-way valve plug 16 are arranged in the radial holes 110, which further ensures the stability of the one-way valve plug 16 in the air guide hole 111 in the initial state, and prevents the one-way valve plug 16 from falling off, resulting in failure of the seal at the air guide hole 111 in the initial state. Of course, in actual implementation, the movable sealing assembly can also directly use rubber plugs or wooden plugs.

[0052] 3. Combination of snap-on assembly and ice-breaking assembly

[0053] like Figure 1 and Figure 2As shown, at least three cylindrical seats 10 are provided, and a frame structure connected end to end is formed between at least three cylindrical seats 10 through a connecting seat 30, and a clamping cavity clamped on the outer periphery of the wire is formed by the frame structure; the connecting seat 30 includes a fixing portion and a latch assembly for plugging and locking the fixing portion with the cylindrical seat 10, and the plugging part of the latch assembly and the cylindrical seat 10 is connected to the launch cavity 12, and the high-pressure gas flowing into the launch cavity 12 and the ice-breaking hammer 14 drive the latch assembly to slide outward to disengage the lock, so that the frame structure disintegrates. In this embodiment, through the cooperation of the ice-breaking assembly and the clamping assembly, the disintegration of the clamping assembly can be achieved after the ice-breaking operation of the ice-breaking assembly is completed, which reduces the process of removing the clamping assembly and the ice-breaking assembly from the cable.

[0054] Specifically, Figure 1 , Figure 2 and Figure 5-7 As shown, the fixing part of the connecting seat 30 is a C-shaped ring 31, and the inner cavity of the C-shaped ring 31 can be sleeved on the outer circumference of the cylindrical seat 10. The inner cavity of the C-shaped ring 31 can be used in conjunction with the pin assembly to achieve fixation with the cylindrical seat 10. Figure 6 As shown, the latch assembly includes two T-shaped outer pins 32 respectively distributed on both sides of the C-shaped ring 31. The T-shaped head of the T-shaped outer pin 32 is elastically driven by the extrusion spring 33 and inserted into the pin hole 11 of the side wall of the cylindrical seat 10. The pin hole 11 is also provided with a T-shaped push head 34, the outer end of which abuts against the head of the T-shaped outer pin 32, and the inner end extends into the firing chamber 12. The inner end of the T-shaped push head 34 is located on the firing path of the ice-breaking hammer 14, and the ice-breaking hammer 14 can cooperate with the inner end of the T-shaped push head 34. When the high-pressure gas flows into the firing chamber 12 and drives the ice-breaking hammer 14 to fire, the ice-breaking hammer 14 generates a thrust to drive the T-shaped push head 34 to slide outward, and at the same time, part of the high-pressure gas enters the pin hole 11 to assist the T-shaped push head 34 to slide outward, so that the T-shaped outer pin 32 is separated from the cylindrical seat 10, thereby unlocking the C-shaped ring 31 and the cylindrical seat 10, so that the cylindrical seat 10 is disassembled.

[0055] On the basis of the above, if Figure 6 As shown, the outer end of the ice-breaking hammer 14 is in a conical structure, which ensures the impact effect when the ice-breaking hammer 14 is launched outward. In addition, the inner end of the T-shaped push head 34 abuts against the conical surface of the ice-breaking hammer 14, and the conical surface and the T-shaped push head 34 form an oblique wedge fit, and the ice-breaking hammer 14 is elastically locked in the launch chamber 12 before the ice-breaking hammer 14 is launched, thereby preventing the ice-breaking hammer 14 from falling out of the launch chamber 12 when the cylindrical seat 10 is inverted.

[0056] Further, such as Figure 1 and Figure 3As shown, when the connecting seat 30 is used in conjunction with the elastic driving component 20, taking an embodiment in which three cylindrical seats 10 are set as an example, the three cylindrical seats 10 include a first cylindrical seat 10a, a second cylindrical seat 10b and a third cylindrical seat 10c, and the connecting seat 30 includes a first connecting seat 30a and a second connecting seat 30b; wherein the inner ends of the first cylindrical seat 10a and the second cylindrical seat 10b are fixed to each other through the first connecting seat 30a and combined to form a V-shaped structure, the elastic driving component 20 is installed on the first cylindrical seat 10a, and the driving part of the elastic driving component 20 is fixed to the third cylindrical seat 10c through the second connecting seat 30b.

[0057] It is worth mentioning that in actual implementation, the number of ice-breaking assemblies can be determined according to the ice coverage on the wires in the corresponding area every year. For example, in areas where the thickness of ice coverage on the wires is small all year round, the number of ice-breaking assemblies can be reduced, that is, there is no need to set an ice-breaking hammer 14 at the end of each cylindrical seat 10. For the cylindrical seat 10 without an ice-breaking hammer 14, the structure of the connecting seat 30 can be adaptively adjusted; taking the connection between the inner ends of the first cylindrical seat 10a and the second cylindrical seat 10b as an example, Figure 1 As shown, the inner end of the first cylindrical seat 10a is not provided with an ice-breaking hammer 14, and the inner end of the second cylindrical seat 10b is provided with an ice-breaking hammer 14, and the connection between the first connecting seat 30a and the second cylindrical seat 10b is provided with a C-shaped ring 31, and the connection with the first cylindrical seat 10a can be directly fixed with bolts. Of course, if the inner ends of the first cylindrical seat 10a and the second cylindrical seat 10b are both provided with ice-breaking hammers 14, the first connecting seat 30a needs to be provided with two C-shaped rings 31 fixed to each other.

[0058] Of course, it is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, but also includes the same or similar structures that can be implemented in other specific forms without departing from the spirit or essential features of the present invention.
