Description

Technical Field

[0001] This utility model relates to the technical field of installation and connection between different components of an overhead transmission line mechanical de-icing device or with an existing tower line system, and particularly to a protruding mating connection structure for an overhead transmission line mechanical de-icing device. Background Technology

[0002] With the development of digitalization and intelligentization of overhead transmission lines, various digital and intelligent monitoring and protection devices have emerged. When these devices are installed at ground potential, they are usually mounted on the transmission line towers or overhead ground wires. When the equipment is installed on the transmission line towers, some state quantities that need to be measured directly on the conductors are difficult to obtain. Therefore, equipotential bonding is also a common installation and connection method. If equipotential bonding is adopted, the existing conventional installation method is to connect the overhead transmission line monitoring and protection equipment to the overhead transmission line through fittings, such as conductor spacers. Correspondingly, the power industry standard "Connecting Fittings" DL / T759—2023 makes relevant provisions on the classification and types of connecting fittings for overhead lines, substations, and power plant distribution equipment, and puts forward standardized requirements for connecting fittings on overhead transmission lines. Utility Model Content

[0003] As the digitalization and intelligentization of overhead transmission lines become a trend, the existing installation connection types are limited and the installation connection methods are too simple. Traditional industry standards are increasingly unable to meet the installation connection requirements of new equipment. For example, DL / T759—2023 only specifies three types of connection hardware: ball-and-socket connections, ring connections, and slotted connections. Furthermore, in traditional connection methods, the connection hardware needs to bear the main weight of the conductor or tower, requiring high strength. The interconnections between different components are also relatively simple, such as U-shaped hanging rings and U-bolts. Moreover, in the existing overhead transmission line tower-line system, connection hardware mainly considers strength constraints (e.g., CN221828578U, CN218771194U, CN101950937A), with relatively low requirements for lightweighting of individual components. When digital and intelligent equipment is installed in the existing tower-line system, it is necessary to minimize the impact on the existing tower-line system. In particular, when these intelligent and digital devices need to be directly installed on conductors, ground wires and related fittings, the original design did not take into account these devices. Therefore, once the devices are added, the safety margin of the original design will be directly affected. Thus, higher requirements are placed on the lightweighting of these newly added digital and intelligent devices.

[0004] Generally, when installing components using bolts, the bolt threads or shanks bear the main forces between the different parts, as shown in the attached diagram of the instruction manual.Figure 1 , Figure 10 and Figure 24 The structure within. Specifically, Figure 1 When the first connecting part 1 and the second connecting part 2 are connected, they are fixedly connected by bolts 5; Figure 10 When the first connecting part 1 and the second connecting part 4 are connected, they are connected by bolts 5; Figure 24 The sleeve opening is connected to the base via four bolts (A, B, C, and D) through the sleeve flange. For the above-mentioned bolted connection method, if lightweight requirements are also considered, the connecting components will largely utilize lightweight materials such as aluminum alloy. This is because lightweight materials like aluminum have lower strength, and connecting them with high-strength steel bolts may lead to bolt thread stripping. On the other hand, unlike traditional passive device connections (DL / T759—2023, CN221828578U, CN218771194U, CN101950937A), overhead transmission line mechanical de-icing devices are typical active devices. The force generated by the autonomous vibration of the overhead transmission line mechanical de-icing device will seriously affect the reliability of the internal or external connections of the de-icing device. If the direction of the force is exactly the same as or perpendicular to the bolt connection direction, the continuous vibration of the de-icing device will severely test the bolt threads, screws, and nuts.

[0005] To improve the strength of bolted connections, common methods include increasing the diameter of the bolt, increasing the length of the threaded connection, and increasing the number of bolts. However, the increasing number of components in digital and intelligent equipment directly leads to more complex connection structures between these components and between components made of different materials. Furthermore, with increasingly limited installation space, the number of components and bolts required for connection is increasing. Therefore, simply increasing the diameter, length, or number of bolts, or improving the strength of the materials, is insufficient to solve the problems of lightweight equipment, limited installation space, and complex connection structures.

[0006] To solve the aforementioned technical problems, this utility model adds protruding parts to the connecting components themselves. Through the interlocking of different connecting components, the connecting components themselves share a portion of the force, which is more conducive to improving the overall structural strength.

[0069] The embodiments of this utility model are described in detail below. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0070] See Figure 2 , Figure 2 This utility model provides a concave-convex mating connection structure for overhead transmission line fittings, including a first connecting component 1 with a first protruding structure 01 and a second connecting component 2 with a second protruding structure 02; the first protruding structure 01 and the second protruding structure 02 mate. When the first protruding structure 01 and the second protruding structure 02 mate, their mating surfaces are either planar or curved.

[0071] The protruding structure involved in this utility model is a structure disposed on the connecting component and protruding from the body of the connecting component. The recessed structure that engages with it is a structure that extends from the surface of the connecting component body into the interior of the connecting component. The protruding structure in this utility model can be a protrusion, a protruding edge, a protruding rim, a boss, or other irregular protruding structure, and the recessed structure in this utility model can be a groove, a recessed hole, or other irregular recessed structure. In fact, convex and concave are relative terms; therefore, whether described as a protruding fit, a convex-concave fit, or a concave-convex fit, it does not affect the description of the structural connection. In the embodiments of this utility model, to strengthen the convex-concave fit between the protruding structure and the recessed structure, the protruding structure can be a boss structure, and the recessed structure can be a groove structure. Specifically, the boss structure can be set as a circular boss or a square boss, and the corresponding groove can be set as a circular groove or a square groove. In the embodiments of this utility model, the protruding structure is set as a square boss structure, and the recessed structure is set as a square groove structure.

[0072] Specifically, the first connecting component 1 has a first protruding structure 01 at one end and a first connecting portion 11 with the second connecting component 2 at the other end; the second connecting component 2 has a second protruding structure 02 at one end and a second connecting portion 21 with the first connecting component 1 at the other end; the first protruding structure 01 includes a first protruding plane 011, which abuts against a plane of the second connecting portion 21. The second protruding structure 02 includes a second protruding plane 021, which abuts against a plane of the first connecting portion 11. The mating surfaces of the first protruding structure 01 and the second protruding structure 02 are folded surfaces or curved surfaces.

[0073] Furthermore, the first protruding structure 01 also includes a first protruding side surface 012, and the second protruding structure also includes a second protruding side surface 022. When the first connecting member 1 and the second connecting member 2 are engaged in a concave-convex fit, the first protruding side surface 012 and the second protruding side surface 022 fit together, increasing the contact area between the first connecting member 1 and the second connecting member 2. The mating surfaces of the aforementioned first protruding structure 01 and second protruding structure 02 are the first protruding side surface 012 and the second protruding side surface 022.

[0074] The first connecting component 1 and the second connecting component 2 are connected by bolts 5, so that the first connecting component 1 and the second connecting component 2 are pressed together. Under the action of the pressing force, the first connecting component 1 and the second connecting component 2 are fixedly connected by the cooperation of the first protruding structure 01 and the second protruding structure 02, while reducing the force on the bolts 5.

[0075] like Figure 2In this configuration, two bolts 5 are provided to connect the first connecting component 1 and the second connecting component 2. Specifically, one bolt 5 is used to fix the first protruding structure 01 and the second connecting part 21 together, and the other bolt 5 is used to fix the second protruding structure 02 and the first connecting part 11 together.

[0076] like Figure 1 As shown, Figure 1 The connection between the existing first connecting component 1 and the second connecting component 2 is described. The first connecting component 1 and the second connecting component 2 are connected by bolts 5. When the first connecting component 1 and the second connecting component 2 are subjected to external forces, causing an interaction force between them, the interaction force will act on the bolt 5, resulting in excessive stress on the bolt 5, which may damage the hardware connection or the equipment connection.

[0077] However, in this embodiment, the first connecting component 1 and the second connecting component 2 are connected by two bolts 5. Because the first protruding structure 01 and the second protruding structure 02 are provided, when the first connecting component 1 and the second connecting component 2 generate an interaction force due to external force, the first protruding side 012 and the second protruding side 022 will contact each other and offset part of the force. Therefore, the force acting on the bolt 5 will be weakened, thereby reducing the stress on the bolt.

[0078] Furthermore, the angle between the first protruding plane 011 and the first protruding side surface 012 in the first protruding structure 01, and the angle between the second protruding plane 021 and the second protruding side surface 022 in the second protruding structure 02, can be set to... Figure 2 The right angle shown, or set as shown Figure 3 The acute angle shown. When all of the above are set to acute angles, the connection relationship between the first connecting component 1 and the second connecting component 2 is set as follows. Figure 3 The structure shown is compared to Figure 2 The institution shown Figure 3 The structure increases the friction between the first connecting part 1 and the second connecting part 2, which can further reduce the stress on the bolt 5.

[0079] See Figure 4 , Figure 4 This is another embodiment of the concave-convex mating connection structure for overhead transmission line fittings provided by this utility model. In addition to the components in the aforementioned embodiments, the structure in this embodiment also includes a third connecting component 3 with a third protruding structure 03. Both the second protruding structure 02 and the third protruding structure 03 mate with the first protruding structure 01.

[0080] like Figure 4 As shown, the second connecting component 2 and the third connecting component 3 are configured to be connected with... Figure 2In the illustrated embodiment, the first connecting component 1 and the second connecting component 2 have the same component structure. Specifically, the second connecting component 2 has a second protruding structure 02 and a second connecting portion 21. The second protruding structure 02 has a second protruding plane 021 and a second protruding side 022. The third connecting component 3 has a third protruding structure 03 and a third connecting portion 31. The third protruding structure 03 has a third protruding plane 031 and a third protruding side 032.

[0081] The first connecting component 1 includes a first protruding structure 01 and a first connecting portion 11. In this embodiment, the first protruding structure 01 includes a front protrusion 013 and a back protrusion 014, which are symmetrical about each other with respect to the line containing the central axis of the first connecting component 1. The front protrusion 013 has a front protruding plane 0131 and a front protruding side 0132, and the back protrusion 014 has a back protruding plane 0141 and a back protruding side 0142. The first connecting portion 11 includes a front connecting portion 111 and a back connecting portion 112. The front protrusion 013 and the front connecting portion 111 are located on the same side of the first connecting component 1, and the back protrusion 013 and the back connecting portion 112 are located on the same side of the first connecting component. In this embodiment, "front" and "back" do not represent actual directions, but rather the relative positional relationship between the two protrusions of the first protruding structure 01.

[0082] In this embodiment, when the first connecting component 1 engages with the second connecting component 2 and the third connecting component 3, the front protruding plane 0131 of the first connecting component 1 abuts against the plane of the second connecting portion 21 of the second connecting component 2, the front protruding side 0132 abuts against the second protruding side 022, and the front connecting portion 111 abuts against the second protruding plane 021; simultaneously, the back protruding plane 0141 of the first connecting component 1 abuts against the plane of the third connecting portion 31 of the third connecting component, the back protruding side 0142 abuts against the third protruding side 032, and the back connecting portion 112 abuts against the third protruding plane 031.

[0083] The first connecting component 1, the second connecting component 2, and the third connecting component 3 are connected simultaneously by bolt 5, so that the second connecting component 2 and the third connecting component 3 press against the first connecting component 1; under the action of the pressing force, the second protruding structure 02 and the third protruding structure 03 cooperate with the first protruding structure 01 to achieve a fixed connection between the second connecting component 2 and the third connecting component 3 and the first connecting component 1, thereby reducing the force on bolt 5.

[0084] Specifically, two bolts 5 are provided. One bolt 5 passes through the second connecting part 21, the front protrusion 013, the back protrusion 014 and the third connecting part 31 at the same time. The other bolt 5 passes through the second protrusion structure 02, the first connecting part 11 and the third protrusion structure 03 at the same time, so as to fix the first connecting part 1 to the second connecting part 2 and the third connecting part 3.

[0085] With the configuration of this embodiment, when the first connecting component 1 and the second connecting component 2, and the first connecting component 1 and the third connecting component 3 generate an interaction force due to external force, the second protruding side 021 and the front protruding side 0132 come into contact with each other, and the third protruding side 031 and the back protruding side 0142 come into contact with each other, which will offset part of the force, weaken the force acting on the bolt 5, and reduce the force on the bolt 5.

[0086] In a specific embodiment of this utility model, the second connecting component 2 and the third connecting component 3 can be configured as follows: Figure 5 The structure shown. In Figure 5 In the structure shown, the second connecting component 2 and the third connecting component 3 are integrally formed. Specifically, the first side of the second connecting component 2 is provided with a second protrusion structure 02, the first side of the third connecting component 3 is provided with a third protrusion structure 03, and the second side of the second connecting component 2 and the second side of the third connecting component 3 are integrally formed.

[0087] Furthermore, the concave-convex mating connection structure of this embodiment can also be... Figure 7 Implemented as shown. (As illustrated) Figure 7 As shown, the first connecting component 1 is provided with multiple first protrusions 01, the second connecting component 2 is provided with multiple second protrusions 02, and the third connecting component 3 is provided with multiple third protrusions 03. The second connecting component 2 and the third connecting component 3 are integrally formed, and any second protrusion 02 on the second connecting component 2 and any third protrusion 03 on the third connecting component 3 are in mutually symmetrical positions.

[0088] Multiple second recessed structures 09 are formed between adjacent second protruding structures 02, and multiple third recessed structures 010 are formed between adjacent third protruding structures 03. One of the multiple first protruding structures 01 corresponds to one of the second recessed structures 09 and one of the third recessed structures 010 in a convex-concave fit. Bolts 5 simultaneously connect the convex-concave fit of the first protruding structures 01, the second recessed structures 09, and the third recessed structures 010, causing the second recessed structures 09 and the third recessed structures 010 to press against the first protruding structure 01. Under the action of the pressing force, the cooperation between the second recessed structures 09, the third recessed structures 010, and the first protruding structure 01 achieves a fixed connection between the second connecting component 2 and the third connecting component 3 and the first connecting component 1, reducing the stress on the bolts 5.

[0089] like Figure 6 As shown, when multiple identical first protrusion structures 01 are provided on the first connecting component 1, a certain interval is provided between adjacent first protrusion structures 01, forming a first recess structure 08 between adjacent first protrusion structures 01; after multiple identical first protrusion structures 01 are provided on the first connecting component 1, multiple first recess structures 08 can be formed on the first connecting component 1. By adjusting the relative positional relationship between the integrally formed structures of the first connecting component 1, the second connecting component 2, and the third connecting component 3, one of the first recess structures 08 can be matched with one of the second protrusion structures 02 and one of the third protrusion structures 03, and the second recess structure 09 and the third recess structure 010 can be matched with the first protrusion structure 01. The above-mentioned matching method is consistent with the matching method of the previous embodiment, and will not be described again in this embodiment.

[0090] See Figure 8 and Figure 9 , Figure 8 This is another embodiment of the concave-convex mating connection structure for hardware used in overhead transmission lines provided by this utility model. Figure 9 yes Figure 8 An exploded view of the structure shown. The structure in this embodiment includes, in addition to, the following... Figure 4 In addition to the components shown in the embodiment, a fourth connecting component 4 with a fourth protrusion structure 04 is also included. The fourth protrusion structure 04 is docked with the first protrusion structure 01 to form a shoulder structure 10.

[0091] The first connecting component 1 in this utility model can have any structure. Specifically, the first connecting component 1 can be set as a cylindrical structure in the shape of a circle, square, triangle or other shapes. In this embodiment, the first connecting component 1 is described using a circular cylindrical structure as an example. A first protrusion structure 01 is provided on the outer side of one end of the cylindrical structure of the first connecting component 1. The first protrusion structure 01 is obtained by covering all or part of the outer side of one end of the cylindrical structure of the first connecting component 1; in this embodiment, it is preferable to obtain the first protrusion structure 01 by completely covering the outer side of the first end of the first connecting component 1.

[0092] In this embodiment, the fourth connecting component 4 and the first connecting component 1 are components that need to be connected. The first connecting component 1 has a first protruding structure 01, and the fourth connecting component 4 has a fourth protruding structure 04. The connection point that connects the first connecting component 1 and the fourth connecting component 4 is the connection of the first protruding structure 01 and the fourth protruding structure 04. In existing connection methods, bolts are used to directly connect the first protruding structure 01 and the fourth protruding structure 04, such as... Figure 10 As shown. But using Figure 10 In the connection method shown, the first connecting component 1 and the fourth connecting component 4 will generate an interaction force due to external forces. This interaction force is concentrated on the connecting bolts provided between the first protruding structure 01 and the fourth protruding structure 04, which puts a strain on the connection strength of the connecting bolts. In this embodiment, in addition to the conventional bolt connection method, a concave-convex fit connection method is added when connecting the first connecting component 1 and the fourth connecting component 4, which can reduce the stress on the bolts and avoid damage.

[0093] Specifically, in this embodiment, the first connecting component 1 has a first protrusion structure 01, and the fourth connecting component 4 has a fourth protrusion structure 04. The first protrusion structure 01 and the fourth protrusion structure 04 are joined together to form a shoulder structure 10; the shoulder structure 10 is as follows: Figure 8 As shown in label 10.

[0094] The second connecting component 2 also includes a fifth protrusion structure 05, which is symmetrically arranged on both sides of the second connecting component 2 with the second protrusion structure 02, forming a fourth recessed structure 20 between them; the structure of the second connecting component 2 is as follows Figure 11 As shown.

[0095] The third connecting component 3 also includes a sixth protruding structure 06, which and the third protruding structure 03 are symmetrically arranged on both sides of the third connecting component 3, forming a fifth recessed structure 30 between them; the structure of the third connecting component 3 is as follows Figure 12 As shown.

[0096] Specifically, the second connecting component 2 is as follows: Figure 11The hollow semi-cylindrical cavity shown has a fourth recessed structure 20, which is disposed on the inner sidewall of the cavity and is arranged circumferentially along the inner sidewall. The third connecting component 3 is as follows: Figure 12 The hollow semi-cylindrical cavity shown has a fifth recessed structure 30, which is disposed on the inner sidewall of the cavity and is arranged circumferentially along the inner sidewall. The outer diameter of the circular cylindrical structure of the first connecting member 1 is equal to or slightly smaller than the inner diameter of the fourth recessed structure 20 and the fifth recessed structure 30, and the fourth recessed structure 20 and the fifth recessed structure 30 can engage with all or part of the shoulder structure 10 to achieve the initial connection of the first connecting member 1, the fourth connecting member 4 and the second connecting member 2. After the shoulder structure 10 and the fourth recessed structure 20 complete the engagement, the third connecting member 3 engages with the second connecting member 2, and the two are pressed against the shoulder structure 10. In other embodiments of this utility model, the fifth recessed structure 30 may not be provided in the third connecting member 3, and the second connecting member 2 and the third connecting member 3 achieve a fixed connection of the shoulder structure 10 by hugging each other.

[0097] The second connecting component 2 and the third connecting component 3 are connected by bolt 5, so that the second connecting component 2 and the third connecting component 3 press against the first connecting component 1 and the fourth connecting component 4. Under the action of the pressing force, the second connecting component 2 and the third connecting component 3 are fixedly connected to the first connecting component 1 and the fourth connecting component 4 through the convex-concave fit between the shoulder structure 10 and the fourth recessed structure 20 and the fifth recessed structure 30, while reducing the stress on the bolt 5.

[0098] Furthermore, Figure 11 A first screw hole 210, a second screw hole 220, a third screw hole 230, and a fourth screw hole 240 are formed from the outer side wall of the second connecting component 2 inward. Figure 12 A fifth screw hole 310, a sixth screw hole 320, a seventh screw hole 330, and an eighth screw hole 340 are respectively opened from one side of the outer wall of the third connecting component 3 inward. All of these screw holes are located on the body of the second connecting component 2 and the third connecting component 3. The first screw hole 210 and the fifth screw hole 310 are connected by the same bolt 5; the second screw hole 220 and the sixth screw hole 320 are connected by the same bolt 5; the third screw hole 230 and the seventh screw hole 330 are connected by the same bolt 5; and the fourth screw hole 240 and the eighth screw hole 340 are connected by the same bolt 5. The installation direction of the bolts 5 is perpendicular to the cylindrical extension direction of the first connecting component 1. Because the bolt 5 is perpendicular to the extension direction of the first connecting component 1, the force generated by the interaction between the four components will act between the shoulder structure 10 and the fourth recessed structure 20 and the fifth recessed structure 30. At this time, the force on the bolt 5 will be greatly reduced, improving the strength of the connection.

[0099] like Figure 13 As shown, in an embodiment of this utility model, a first positioning post 61 is fixedly provided on the first protruding structure 01, and a first positioning hole 62 is provided on the side wall of the second connecting component 2 and / or the third connecting component 3. The first positioning post 61 passes through the corresponding first positioning hole 62 and is inserted into the first positioning hole 62 of the second connecting component 2 and / or the third connecting component 3 to fix the relative position between the first connecting component 1 and the second connecting component 2 and / or the third connecting component 3.

[0100] Simultaneously, a second positioning post is fixedly installed on the fourth protruding structure 04, and a through second positioning hole is provided on the side wall of the second connecting component 2 and / or the third connecting component 3. The second positioning post is inserted into the corresponding second positioning hole to fix the relative position between the fourth connecting component 4 and the second connecting component 2 and / or the third connecting component 3. The arrangement of the second positioning post and the second positioning hole on the fourth connecting structure 4 is the same as the arrangement of the first positioning post 61 and the first positioning hole 62 on the first connecting structure 1, and will not be described again.

[0101] Specifically, at least one first positioning post 61 is fixedly provided on the first protruding structure 01 of the first connecting component 1, and the first positioning post 61 is arranged radially along the circumference of the cylindrical body of the first connecting component 1; the same number of first positioning holes 62 are correspondingly provided on the fourth recessed structure 20 and / or the fifth recessed structure 30. Through the cooperation of the first positioning post 61 and the first positioning hole 62, the relative position between the first connecting component 1 and the second connecting component 2 and / or the third connecting component 3 can be kept constant. The first positioning hole 62 is as follows... Figure 19 As shown in the image.

[0102] At least one second positioning post is fixedly provided on the fourth protrusion structure 04 of the fourth connecting component 4. The second positioning post is arranged radially along the circumference of the cylinder of the fourth connecting component 4. The same number of second positioning holes are provided on the fourth recess structure 20 and / or the fifth recess structure 30. By cooperating with the second positioning post and the second positioning hole, the relative position between the fourth connecting component 4 and the second connecting component 2 and / or the third connecting component 3 can be kept unchanged.

[0103] This utility model provides a connection structure based on a protrusion fit, which can replace the existing connection structure, reduce the stress on the bolts at the connection points, and further improve the service life of the equipment. Figure 24 As shown, Figure 24 This illustrates the connection method used when connecting components to other components. Typically, a screw hole is provided on the outer edge of the end of the connecting component, and the connecting component is connected to other components by bolts. The bolts are set in the same direction as the extension direction of the connecting component. Figure 24The ABCD shown are the bolts used to connect the first connecting component 1 to other components. In this structure, if the equipment is under vibration or stress during operation, the direction of the vibration or stress is usually consistent with the extension direction of the connecting component. The vibration or stress will generate force, which will act on the bolts that fix the connecting component to other connecting components. Long-term stress may cause the bolts to come off, causing the connecting component to separate from other connecting components and resulting in equipment damage.

[0104] Therefore, this utility model provides a novel connection structure. When the first connecting component 1 and the second connecting component 2 are connected, the force between the first connecting component 1 and the second connecting component 2 is concentrated on the concave-convex structure through the cooperation of the groove structure and the protrusion structure. This reduces the stress on the bolt 4 connecting the second connecting component 2 and the third connecting component 3, thus protecting the equipment and extending its service life.

[0105] The concave-convex mating connection structure of this utility model is practically applied to mechanical de-icing devices for overhead power transmission lines. For example... Figure 14 In this embodiment, the vibrating cylinder 100 of the mechanical de-icing device is the first connecting component 1. Both ends of the vibrating cylinder 100 are provided with first protruding structures 01, and both ends are connected to corresponding components in the mechanical de-icing device for overhead transmission lines using the protrusion-fitting connection structure provided in this utility model. Specifically, one end of the vibrating cylinder 100 is connected to the reduction gearbox 200 of the mechanical de-icing device, such as... Figure 17 and Figure 18 As shown, where Figure 17 This is a schematic diagram showing the design of a fixed connection between the vibrating cylinder 100 and the reduction gearbox 200 via a protruding engagement connection structure. Figure 18 It corresponds Figure 17 An explosion diagram; the other end of the vibrating cylinder 100 is connected to the clamp 300 used to connect the overhead line conductors, the specific connection structure is as follows. Figure 20 and 20 As shown, among them Figure 20 This is a schematic diagram of the design for a fixed connection between the vibrating cylinder 100 and the wire clamp 300 via a protruding engagement structure. Figure 21 It corresponds Figure 20 An explosion diagram.

[0106] exist Figure 17 and Figure 18 In the structure shown, the second connecting component 2 is integrated into the gearbox 200 of the mechanical de-icing device, and its specific structure is as follows: Figure 15 As shown, Figure 15The second connecting component 2 shown is provided with a second protruding structure 02, and a fourth recessed structure 20 is formed between the second protruding structure 02 and the outer wall of the gearbox 200. The structure of the third connecting component 3 is as follows: Figure 16 As shown, the third connecting component 3 is provided with a third protruding structure 03. When the third connecting component 3 and the second connecting component 2 are engaged, a fifth recessed structure 30 is formed between the second protruding structure 02 and the outer wall of the gearbox 200 of the mechanical de-icing device. Through the concave-convex fit between the fourth recessed structure 20 and the fifth recessed structure 30 and the first protruding structure 01 of the first connecting component 1, the first connecting component 1 can be pressed tightly by the second connecting component 2 and the third connecting component 3. Under the action of the pressing force, the second connecting component 2 and the third connecting component 3 are fixedly connected to the first connecting component 1. Furthermore, the second connecting component 2 and the third connecting component 3 are fixedly connected by bolts 5. The aforementioned concave-convex fit can greatly reduce the stress on the bolts 5 connecting the second connecting component 2 and the third connecting component 3. At the same time, the third connecting component 3 is also fixedly connected to the outer wall of the gearbox 200 by bolts, further improving the connection strength between the first connecting component 1, the second connecting component 2, and the third connecting component 3.

[0107] exist Figure 20 and Figure 21 In the structure shown, the second connecting component 2 is integrated into the clamp 300 that securely connects the mechanical de-icing device to the overhead transmission line conductor. The clamp 300 can be a standard clamp, a rotary clamp, or an induction clamp. Figure 20 In the embodiment shown, the structure of the second connecting component 2 is as follows: Figure 19 As shown, the second connecting component 2 is fixedly connected to the wire clamp 300. The second connecting component 2 adopts the following... Figure 11 The structure shown in the figure, the third connecting component 3 adopts as follows Figure 12 The structure is shown. The first protruding structure 01 of the first connecting component 1 engages with the fourth recessed structure 20 of the second connecting component 2 and the fifth recessed structure 30 of the third connecting component 3, thereby pressing the first connecting component 1 together through the second connecting component 2 and the third connecting component 3. Under the action of the pressing force, the second connecting component 2 and the third connecting component 3 are fixedly connected to the first connecting component 1. Furthermore, the second connecting component 2 and the third connecting component 3 are fixedly connected by bolts 5. The aforementioned engagement can greatly reduce the stress on the bolts 5 connecting the second connecting component 2 and the third connecting component 3.

[0108] like Figure 22As shown, the first connecting component 1 and the fourth connecting component 4 adopt the same cylindrical structure as in the previous embodiment. One end of the first connecting component has a first protruding structure 01; one end of the fourth connecting component has a fourth protruding structure 04; the first protruding structure 01 and the fourth protruding structure 04 are joined together to form a shoulder structure 10. Through the fourth recessed structure 20 provided by the second connecting component 2 and the fifth recessed structure 30 provided by the third connecting component 3, a concave-convex fit is achieved with the shoulder structure 10, thus realizing the fixed connection of the first connecting component 1 and the fourth connecting component 4, connecting the two cylindrical structures that need to be joined. Further, by connecting the second connecting component 2 and the third connecting component 3 with bolts, the second connecting component 2 and the third connecting component 3 can clamp the first connecting component 1 and the fourth connecting component.

[0109] In some embodiments of this utility model, such as Figure 23 In the middle, it is necessary to Figure 13 The port of the first connecting component 1 shown can be closed by the second connecting component 2 and the third connecting component 3 engaging with it in a concave-convex fit. The concave-convex fit between the first connecting component 1 and the second and third connecting components 2 and 3 is as described in the previous embodiment. The first connecting component 1 has a first protruding structure 01, which can engage with the fourth recessed structure 20 in the second connecting component 2 and the fifth recessed structure 30 in the third connecting component 30.

[0110] Unlike existing technologies, this utility model provides a protruding mating connection structure for a mechanical de-icing device for overhead transmission lines. It includes a first connecting component with a first protruding structure and a second connecting component with a second protruding structure. The first and second protruding structures mate. Bolts connect the first and second connecting components, pressing them together. Under the pressure of this clamping force, the first and second connecting components are connected through the mating of the first and second protruding structures, while simultaneously reducing bolt stress. This utility model can be used for connections between internal components of a mechanical de-icing device for overhead transmission lines, and between the mechanical de-icing device and other components of the overhead transmission line, such as conductor spacers, conductors, and ground wires, reducing the probability of damage to components or the entire mechanical de-icing device due to connection issues.
