Description

Technical Field

[0001] This utility model relates to the field of anti-icing and de-icing technology for overhead lines or railway contact networks, specifically to an assembly structure suitable for mechanical de-icing devices for overhead lines. Background Technology

[0002] The problem of icing on overhead lines has always been one of the most serious natural disasters in the power system at home and abroad. Mechanical de-icing is a conventional method for preventing and removing ice on overhead lines. Utility model [1] "Mechanical Vibration De-icing Device" (CN201417921Y), utility model [2] "High-rise Cable Air Explosion Vibration De-icing Device" (CN201549858U), and utility model [3] "A Mechanical Vibration De-icing Device for Overhead Ground Wire" (CN201247941Y) all work on the principle of driving the overhead line conductors or ground wires to vibrate through energy units and mechanical mechanisms to carry out anti-icing and de-icing operations. In this regard, the state has also issued corresponding industry standards, "Technical Guidelines for the Use of Mechanical Vibration De-icing Devices for Overhead Transmission Line Conductors and Ground Wires" (DL / T 1922-2018), which makes relevant specifications for de-icing operations and de-icing processes. However, the energy source of the power units of the above utility models all use pyrotechnics, which greatly limits the application scenarios, application scope and application conditions. Moreover, the de-icing process requires not only power outages but also extensive manual intervention, resulting in low operational efficiency. To address this, utility models such as [4] "Anti-icing and de-icing device, spacer, system and anti-galloping system based on center of gravity change" (CN115642555A), [5] "Anti-icing and de-icing device, spacer, post insulator and system for overhead lines" (CN115483658B), and [6] "Anti-icing and de-icing device for split conductors of overhead lines, spacer and system for sub-conductors" (CN115632367A) have proposed an overhead line mechanical vibration de-icing device that uses a motor as the power unit and a spring as the energy storage and release device. This not only avoids the limitations of using pyrotechnics but also requires minimal manual intervention, achieving de-icing without power outages and with less manual intervention, thus significantly improving the efficiency of anti-icing and de-icing. Utility Model Content

[0003] Overhead line mechanical vibration de-icing devices are installed on the conductors or ground wires of overhead lines. This installation location not only makes installation difficult but also requires a high degree of lightweight design, demanding high mass energy density and volume energy density—that is, generating a strong vibration effect with a small mass and volume. Furthermore, the conductors and ground wires of overhead lines cannot directly provide energy, making it very difficult to obtain the energy for the device's vibration. Generally, energy is collected from solar or wind power, or from the magnetic field energy around the current-carrying conductors. This necessitates high transmission efficiency to generate sufficient vibration with relatively limited energy to meet the de-icing requirements of overhead lines.

[0004] The utility models mentioned in the background [4~6] propose related transmission components in anti-icing and de-icing devices, such as motors, reduction mechanisms, clutch mechanisms, springs, and other transmission or energy storage and release components. These components all need to be mounted on a base. The base is actually the assembly structure of the entire anti-icing and de-icing device. Due to the aforementioned objective conditions, it is particularly important to rationally design the assembly structure of the overhead line mechanical vibration de-icing device, especially the main structure. In addition to considering constraints such as energy density, lightweighting, and energy utilization efficiency, it is also necessary to rationally select the components of the entire structure. Generally, it is necessary to comprehensively weigh and compromise on various aspects such as mechanical performance, working condition adaptability, process matching, and cost control. Among them, the design of the gearbox and related transmission system is a highly systematic and iterative process. It is necessary to find the best balance between multiple dimensions such as functional performance indicators, transmission efficiency, structural strength and reliability, manufacturing feasibility, cost control, and maintenance convenience. It is necessary to avoid having too few components and complex processing technology, and also to avoid having too many components, resulting in high assembly costs and complex installation procedures.

[0005] In the design of the main structure of the device in this application, the following factors need to be considered: First, the overall main structure of the device needs to be determined, and all other supporting parts need to be installed on the main structure. Second, the various components need to maintain a certain connection relationship and be reasonably installed on the entire assembly structure to meet the requirements of force transmission and energy storage and release between different components. It needs to have a certain strength, as well as high transmission efficiency and overall reliability. Third, the overhead line mechanical de-icing device itself achieves anti-icing and de-icing of overhead lines through vibration. However, as a vibration source, some components of the device itself have severely insufficient vibration tolerance, such as the motor rotor, motor brushes, and related circuit components; and the reduction gears and reduction components of planetary or cycloidal reduction gears. Because of the existence of these relatively precise components, sufficient vibration damping protection must be provided for these components when designing the main structure of the device. Fourth, the gearbox and related transmission system need to ensure sufficient wall thickness and reasonably distributed reinforcing ribs, as well as the thickness and spacing of the rib plates, while ensuring lightweight and transmission efficiency, to ensure the overall rigidity and local support rigidity of the gearbox. Fifth, the assembly structure also needs to consider the installation process between different components. Facilitating installation, ensuring high standardization of parts, and reducing the overall variety and quantity of components are beneficial for cost reduction and overall structural lightweighting. Sixth, the various assembly components have simple processing techniques, are easy to manufacture, and have low costs. Considering the above factors, how to design and optimize such an assembly structure, how to rationally install, fix, and connect these components to better suit the actual operating environment, improve de-icing efficiency, and enhance the overall reliability of the device, requires a comprehensive consideration of the entire device's load spectrum, lightweighting, transmission efficiency, and vibration damping protection of key components. Balancing trade-offs between different technical indicators such as overall lightweighting and transmission efficiency are key issues that need to be addressed.

[0006] To address the aforementioned constraints and the need for comprehensive compromises, this application focuses on optimization measures in the following aspects: First, the worm gear, worm shaft, gear, incomplete gear, rack, and winding shaft are integrated into a single gearbox housing, forming a gearbox structural component. This gearbox structural component serves as the main structure of the entire device, with all other related components assembled onto it. This not only ensures the overall structural strength of the gearbox structural component and reduces the mass and volume of the device but also improves the overall transmission efficiency. Second, the gearbox housing is split along the axial direction of the worm shaft, facilitating the installation of the worm gear, worm shaft, and incomplete gear. Figure 17 In the related technology shown, the motor, multi-stage reduction mechanism, worm gear, and worm share a first chamber 1A, while the incomplete gear, rack, and spring share a second chamber 1D. These two chambers are then fixedly connected, and a coupling drives the transmission between them. Figure 1, Figure 8 It is aimed at Figure 17 This is an improved and upgraded version of the original plan. Compared to... Figure 17 The split structure of the gearbox designed in this application has strong overall structural integrity, high transmission efficiency, simple split structure, and relatively simple installation process. Thirdly, the first chamber containing the worm gear and worm shaft shares a wall with the second chamber containing the incomplete gear and rack (or the chamber containing the incomplete gear and rack, or the chamber containing the winding shaft). Under the same conditions, it is lighter, has better strength and rigidity, better overall structural integrity of the gearbox, and relatively higher transmission efficiency. Compared to... Figure 17The gearbox structural components of this application have significant structural and performance advantages. Fourthly, the motor and multi-stage reduction mechanism are the weakest links in the entire device, exhibiting poor vibration resistance. Improving the motor's vibration resistance and improving the system's transmission efficiency are inherently contradictory. Improving transmission efficiency requires rigid transmission, while improving vibration resistance precludes rigid connections, preventing vibration transmission to the motor and multi-stage reduction mechanism. In this application, a flexible coupling, elastic coupling, or flexible coupling (rigid or flexible couplings are defined and classified according to GB / T 12458-2017 Coupling Classification) is added between the output end of the motor structural components and the input end of the gearbox structural components, thus improving the vibration resistance of the motor and multi-stage reduction mechanism to a certain extent. Simultaneously, adding an elastic buffer pad between the motor structural components and the gearbox structural components also improves vibration resistance to a certain degree. In fact, further vibration damping measures can be taken inside the motor structural components to provide more comprehensive protection for the motor and multi-stage reduction mechanism. Fifth, the appropriate use of rigid, flexible, elastic, or flexible transmission connections improves transmission efficiency while ensuring the overall reliability of the device and protecting weaker components with poor vibration resistance. In the transmission system of the entire device, the initial stage has a higher speed, while the subsequent stage has a lower speed. From the initial stage to the subsequent stage, it includes: a motor, a multi-stage reduction mechanism, a worm gear, a worm shaft, incomplete gears, and energy storage and release mechanisms corresponding to moving parts and springs. Generally, rigid connections have higher transmission efficiency, while flexible connections have lower efficiency. However, rigid connections place higher demands on machining accuracy, assembly conditions, and the vibration resistance of related components. Therefore, the number and proper installation position of flexible or elastic couplings are crucial to the overall performance of the device. Installing flexible or elastic couplings too far forward will affect the overall transmission efficiency. Installing them too far backward will result in excessively large flexible or elastic couplings, affecting the energy density of the device. Furthermore, the specific installation location of flexible or elastic couplings needs to be considered, as well as weak points in the protection device with poor vibration resistance. This application reduces the number of flexible or elastic couplings used through the integrated design of the gearbox structural components, and rationally arranges the transmission positions of the flexible or elastic couplings. Under the condition of meeting overall performance requirements such as machining accuracy, assembly conditions, and vibration resistance, the transmission efficiency is relatively high. Sixth, addressing the issue of unnecessary axial bending of springs under stress, this application fully utilizes existing structural components to constrain the deformation direction of the spring and avoid unnecessary energy loss. The spring shell of the spring structural components forms the outer slide cylinder, and the rack forms the inner slide rod, constraining the spring deformation direction without adding additional components.

[0007] This utility model proposes an assembly structure applicable to, but not limited to, the base or housing in utility models [1-6]. The assembly structure is divided into three parts: a gearbox structure component, a motor structure component, and a spring structure component. Using the gearbox structure component as the main structural component facilitates the overall installation of the worm gear, worm shaft, and incomplete gear, which bear significant forces, within the gearbox housing. This results in good integrity, high transmission efficiency, and light weight. Furthermore, the housing is easily sealed, which is beneficial for lubrication. Using the motor structure component not only improves the overall vibration resistance of the device but also facilitates the standardization of product components and the replacement of different motor models. Using the spring structure component, with the spring housing as a separate part of the assembly structure, not only facilitates the selection of different springs but also allows for the selection of different spring housings based on the spring, thus facilitating the standardization of product components. The assembly structure in this application has a reasonable layout, compact connections, light weight, and high transmission efficiency, effectively meeting the actual operational needs of the anti-icing and de-icing devices in utility models [1-6]. It possesses strong novelty, inventiveness, and practicality.

[0008] This utility model provides an assembly structure suitable for mechanical de-icing devices for overhead lines, aiming to provide an assembly structure with reasonable layout, compact connection, light weight, and high transmission efficiency, which better meets the reliability requirements of actual operation of anti-icing and de-icing devices.

Detailed Implementation

[0049] 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.

[0050] See Figures 1-11 , Figure 1 and Figure 8 The present invention provides an assembly structure for a mechanical de-icing device for overhead power lines, the assembly structure comprising a motor structure component 1, a gearbox structure component 2, and a spring structure component 3; the motor structure component 1 and the spring structure component 3 are fixedly mounted on the gearbox structure component 2. Figure 3 The structure shown is an exploded view of the assembly structure of this utility model.

[0051] Motor structural component 1 includes a motor 11 and a motor housing 12. The motor 11 is installed inside the motor housing 12, which protects, fixes, and mounts the motor 11. Gearbox structural component 2 includes a gearbox housing 21, a worm gear 22, a worm 23, and an incomplete gear 24. The worm gear 22, worm 23, and incomplete gear 24 are all fixedly installed inside the gearbox housing 21. The worm gear 22 and worm 23 mesh with each other to form a worm gear mechanism, and the motor 11 is driven by the worm 23. Spring structural component 3 includes a spring 31, a spring housing 32, and a moving part. The spring 31 and the moving part are both housed within the spring housing 32, and the incomplete gear 24 is driven by the moving part.

[0052] In this embodiment, the motor housing 12, the gearbox housing 21, and the spring housing 32 are the supporting housings of the overhead line mechanical de-icing device. The other actuating mechanisms of the overhead line mechanical de-icing device are all fixedly installed in the supporting housing composed of the motor housing 12, the gearbox housing 21, and the spring housing 32.

[0053] In other embodiments of this utility model, a multi-stage reduction mechanism 13 is provided inside the motor housing 12. The input end of the multi-stage reduction mechanism 13 is connected to the output end of the motor 11, and the output end of the multi-stage reduction mechanism 13 serves as the output end of the motor structural component 1. The output end of the multi-stage reduction mechanism 13 is connected to the worm gear mechanism in the reduction gearbox housing 21. The multi-stage reduction mechanism 13 can be composed of multiple reduction mechanisms of the same type connected in series, or it can be composed of multiple reduction mechanisms of different types connected in series. Optionally, the multi-stage reduction mechanism 13 is composed of cascaded multi-stage planetary gear reduction mechanisms or cascaded multi-stage cycloidal reduction mechanisms. Furthermore, the multi-stage reduction mechanism 13 and the worm gear mechanism are connected by a coupling 14.

[0054] like Figure 4 As shown, the gearbox housing 21 of the gearbox structural component 2 is configured as a split structure along the axial direction of the worm 23 to facilitate the installation of the worm wheel 22, worm 23, and incomplete gear 24. That is, the gearbox housing 21 consists of two parts: a first gearbox housing 211 and a second gearbox housing 212. The first gearbox housing 211 and the second gearbox housing 212 are combined to form the gearbox housing 21. The first gearbox housing 211 and the second gearbox housing 212 are both integral structures, allowing the chambers containing the worm wheel 22 and worm 23 and the chamber containing the incomplete gear 24 to share a portion of the wall. This results in better overall integrity and higher structural strength for both the first gearbox housing 211 and the second gearbox housing 212. The straight line of the connecting joint between the first gearbox housing 211 and the second gearbox housing 212 is parallel to the axial direction of the worm 23 installed inside the gearbox housing 21, and both are in the same plane.

[0055] Furthermore, observation windows are respectively provided on the side walls of the first gearbox housing 211 and the second gearbox housing 212. These observation windows are covered by cover plates, which are bolted to the gearbox housing 21. The purpose of providing these observation windows is to facilitate observation of the interior of the gearbox housing 21 and also to facilitate the installation of various parts housed inside the gearbox housing 21. For example... Figure 1 The number 203 shown is the first cover plate. Figure 5The reference numeral 204 shown is the second cover plate. Both the first cover plate 203 and the second cover plate 204 in the figure are circular. However, the first cover plate 203 and the second cover plate 204 can also be set to any other suitable shape.

[0056] like Figure 12 As shown, the circumference of the incomplete gear 24 includes a toothed portion 242 and a smooth portion 241. The toothed portion 242 of the incomplete gear 24 is a segment of teeth of a predetermined length arranged along the circumference of the incomplete gear 24. The portion of the incomplete gear 24 without teeth along its circumference is the smooth portion 241, and the sum of the lengths of the toothed portion 242 and the smooth portion 241 is equal to the circumference of the incomplete gear 24. When the toothed portion 242 engages with the moving part, the incomplete gear 24 drives the moving part to move, causing the spring 31 to deform and accumulate elastic potential energy. When the smooth portion 241 engages with the moving part, the incomplete gear 24 disengages from the moving part, the spring 31 recovers its deformation and releases its elastic potential energy, and the moving part moves under the action of the elastic potential energy and impacts the spring housing 32.

[0057] When the motor structural component 1 and the spring structural component 3 are fixedly connected to the gearbox structural component 2, the internal and external structures need to be connected simultaneously. Specifically, the internal connection includes: the multi-stage reduction mechanism 13 installed inside the motor structural component 1 is connected to the worm gear 23 inside the gearbox structural component 2 via a coupling 14; the moving component inside the spring structural component 3 includes two implementation methods: When the moving part is a rack 34, the rack 34 inside the spring structure 3 meshes with the incomplete gear 24 in the gearbox structure 2 for transmission; when the moving part includes a winding shaft 25, a flexible connecting part 26, a complete gear 27 and a heavy impact block 33, the heavy impact block 33 is connected to the winding shaft 25 in the gearbox structure 2 through the flexible connecting part 26.

[0058] The external connections include: the motor housing 12 of the motor structure component 1 is fixedly connected to the gearbox housing 21 of the gearbox structure component 2, and the spring housing 32 of the spring structure component 3 is fixedly connected to the gearbox housing 21 of the gearbox structure component 2; optionally, the motor housing 12 and the spring housing 32 are fixedly installed on the same side of the gearbox housing 22. This arrangement facilitates installation and improves the overall consistency of the device.

[0059] In other embodiments of this utility model, the motor housing 12 and the gearbox housing 21, as well as the spring housing 32 and the gearbox housing 21, are connected by a protrusion-fitting method. Specifically, when the motor housing 12 and the gearbox housing 21 are fixedly connected, the position on the motor housing 12 that connects to the gearbox housing 21 is set as a protruding structure, and the position on the gearbox housing 21 that connects to the motor housing 12 is set as a recessed structure adapted to the protruding structure. The protruding and recessed structures are fitted together, and bolts are used for connection, to achieve a fixed connection between the gearbox housing 21 and the motor housing 12.

[0060] In other embodiments of this utility model, an elastic buffer component is provided at the connection point between the motor housing 12 and the gearbox housing 21 for shock absorption; an elastic buffer component is also provided between the motor housing 12 and the spring housing 32 for shock absorption; when the motor 11 is installed inside the motor housing 12, an elastic buffer component is also provided between the motor housing 12 and the motor 11 for shock absorption. Specifically, the motor structural component 1 and the gearbox structural component 2 are fixedly connected by an elastic buffer pad to improve the motor 11's ability to withstand vibration and impact. The motor 11 and the motor housing 12 are fixedly connected by an elastic buffer pad, or the two are fixedly connected by potting with filling adhesive to improve the motor 11's ability to withstand vibration and impact.

[0061] As mentioned above, in the embodiments of this utility model, based on different overhead line mechanical de-icing principles, the moving parts in the spring structure component 3 correspond to different implementation structures.

[0062] like Figure 2As shown, in one embodiment of this utility model, the moving component includes a rack 34. Specifically, the motor 11 in the motor structure component 1 provides power to the overhead line mechanical de-icing device in this embodiment. The input end of the motor 11 is connected to a power source or other power generation equipment for power supply. After the electrical energy from the external power source or external power generation equipment is provided to the motor 11, the motor 11 outputs kinetic energy or torque. In this embodiment, after the motor housing 12 in the motor structure component 1 and the gearbox housing 21 in the gearbox structure component 2 are fixedly connected, the output end of the motor 11, which is located inside the motor housing 12, is connected to the worm gear mechanism located in the gearbox housing 21 to realize the transmission of kinetic energy or torque. Specifically, the output end of the motor 11 is connected to the input end of the multi-stage reduction mechanism 13. The output end of the multi-stage reduction mechanism 13 is coaxially driven with the worm 23 in the worm gear mechanism through the coupling 14, which can transmit the power or torque output by the motor 11 to the worm 23 in the worm gear mechanism. The worm wheel 22 meshes with the worm 23, and the incomplete gear 24 is coaxially driven with the worm wheel 22, thereby transmitting the power and torque to the incomplete gear 24, causing the incomplete gear 24 to start rotating. The incomplete gear 24 is configured to mesh with the rack 34, causing the rack 34 to move in a specified direction. Optionally, the coupling 14 is a flexible coupling or an elastic coupling.

[0063] In the spring structure component 3, one end of the rack 34 is placed inside the spring housing 32, and the other end passes through the gearbox housing 21; one end of the spring 31 is connected to the rack 34, and the other end is connected to the spring housing 32, and the spring 31 is confined within the spring housing 32. Optionally, a base 38 can be fixedly provided at the end of the rack 34 placed inside the spring housing 32; the spring 31 is sleeved on the outside of the rack 34, and one end of the spring 31 is fixedly connected to the base 38; a spring bracket 39 is provided, which is a ring structure, sleeved on the outside of the rack 34, and fixedly connected to the other end of the spring 31; by fixing the spring bracket 39 inside the spring housing 32, the end of the spring 31 connected to it can be fixed.

[0064] In actual operation, the incomplete gear 24 can drive the rack 34 and the spring 31. Specifically, through the meshing transmission of the toothed part 242 of the incomplete gear 24 and the rack 34, the rack 34 is displaced relative to the spring housing 32. One end of the rack 34 is fixedly connected to one end of the spring 31 through the base 38, while the other end of the spring 31 is limited by being connected to the spring bracket 39. Therefore, when the rack 34 is displaced relative to the spring housing 32, the movement of the rack 34 causes the spring 31 to deform, and the spring 31 accumulates elastic potential energy due to the deformation.

[0065] When the incomplete gear 24 rotates to the point where the smooth part 241 engages with the rack 34, the incomplete gear 24 and rack 34 disengage from the transmission, the rack 34 stops moving, the spring 31 is no longer under force and returns to its original deformation, instantaneously releasing elastic potential energy. As the spring 31 returns to its original deformation, it drives the rack 34 to move rapidly, generating an instantaneous thrust on the base 38, causing the base 38 to impact the bottom of the spring housing 32 at a certain speed. The outer side of the spring housing 32 is connected to the overhead line conductor or ground wire through auxiliary connecting components such as wire clamps, causing the overhead transmission line or railway contact network to vibrate, achieving the effect of anti-icing or de-icing.

[0066] like Figure 7 As shown, in this embodiment, to accommodate the large extension and retraction stroke of the spring 31, a first gear 201 and a second gear 202 are added to the gearbox structural component 2. Specifically, the worm gear 22 and the incomplete gear 24 are configured for coaxial transmission, the first gear 201 and the second gear 202 are configured for coaxial transmission, and the tooth portion 242 of the incomplete gear 24 meshes with the teeth of the second gear 202, while the teeth of the first gear 201 mesh with the teeth of the rack 34.

[0067] By controlling the speed and running time of the motor 11, the motor 11 outputs power or torque, which is then transmitted sequentially to the multi-stage reduction mechanism 13, worm 23, worm wheel 22, incomplete gear 24, second gear 202 and first gear 201, and finally to the rack 34. The teeth of the first gear 201 mesh with the teeth of the rack 34, causing the rack 34 to move relative to the spring housing 32, thereby deforming the spring 31 and accumulating elastic potential energy.

[0068] As the incomplete gear 24 continues to rotate, when its smooth portion 241 engages with the second gear 202, the incomplete gear 24 disengages from the second gear 202. The incomplete gear 24 can no longer transmit power or torque to the second gear 202, and at this point, no power or torque is transmitted to the rack 34. The spring 31 also recovers its deformation due to the rack 34 disengaging from the transmission, releasing its elastic potential energy. When the spring 31 releases its elastic potential energy, it drives the rack 34 to move in the opposite direction, generating a momentary thrust on the base 38, causing the base 38 to impact the bottom of the spring housing 32 at a certain speed. The outer side of the spring housing 32 is connected to the overhead line conductor or ground wire via clamps and other auxiliary connecting components, causing the overhead transmission line or railway contact network to vibrate, achieving the effect of anti-icing or de-icing.

[0069] Furthermore, a wear-resistant copper sleeve is provided between the rack 34 and the gearbox housing 21. The wear-resistant copper sleeve is placed on the outside of the rack 34 and fixedly mounted on the gearbox housing 21. When the rack 34 moves telescopically relative to the gearbox housing 21, if the direction of movement of the rack 34 deviates, it will first come into contact with the wear-resistant copper sleeve. The wear-resistant copper sleeve can protect the rack 34, preventing wear and preventing direct contact between the rack 34 and the gearbox housing 21 that could damage the equipment. In this embodiment of the invention, the wear-resistant copper sleeve is located near the spring bracket 39, or the wear-resistant copper sleeve can be directly set as the spring bracket 39. A wear-resistant pad is provided at the connection between the spring 31 and the spring bracket 39 to prevent friction between the spring 31 and the spring bracket 39 and to provide shock absorption.

[0070] To accumulate more elastic potential energy, this invention achieves this by lengthening the spring 31. Figure 5 As shown in the structure. Figure 5 The length of spring 31 has been increased, and the length of the spring housing used to mount spring 31 has also increased accordingly. Figure 5 The length ratio of the spring structure component 3 to the motor structure component 1 is significantly greater than that of the spring structure component 3. Figure 1 and Figure 3 The length ratio of the spring structure component 3 to the motor structure component 1 is specifically reflected in the fact that the length of the spring housing 32 is increased while keeping the length of the motor housing 12 unchanged.

[0071] In this embodiment, an outer slide cylinder is provided on the outside of the spring 31 to restrict the deformation direction of the spring. Figure 2 In the structure shown, the spring housing 32, which is located outside the spring 31, serves as the outer slide cylinder.

[0072] In this embodiment, an inner slide rod is provided inside the spring 31 to limit the deformation direction of the spring 31. Figure 6 In the structure shown, the rack 34 located inside the spring 31 serves as an inner slide bar.

[0073] like Figure 9As shown, in another embodiment of this utility model, the moving component includes a winding shaft 25, a complete gear 27, and a heavy impact block 33. In this embodiment, the winding shaft 25 and the complete gear 27 are disposed inside the gearbox housing 21. The teeth of the complete gear 27 mesh with the tooth portion 242 of the incomplete gear 24, and the gear shaft of the complete gear 27 is coaxially connected to the winding shaft 25, specifically, it can be configured as coaxial transmission or integrally formed. One end of the winding shaft 25 is fixedly connected to the flexible connecting component 26, and the other end of the flexible connecting component 26 is fixedly connected to the heavy impact block 33. A spring 31 is disposed inside the spring housing 32, one end of the spring 31 is connected to the heavy impact block 33, and the other end is connected to the spring housing 32.

[0074] The impact block 33 involved in this utility model is an object with a certain mass. It can be made of a high-density solid material with a certain degree of hardness, elasticity, or toughness, which is beneficial to improving the vibration effect generated by the device. The mass of the impact block 33 and the parameters of the spring 31 are selected comprehensively according to the vibration effect required by the device.

[0075] Specifically, the teeth of the complete gear 27 mesh with the teeth 242 of the incomplete gear 24. The rotation of the incomplete gear 24 drives the rotation of the complete gear 27. The gear shaft of the complete gear 27 and the winding shaft 25 are coaxially driven or integrally formed, so the winding shaft 25 can be driven to rotate by the complete gear 27. The flexible connecting component 26, which is fixed on the shaft of the winding shaft 25, begins to wind on the winding shaft 25. By controlling the rotation direction of the motor 11, the flexible connecting component 26 pulls the heavy impact block 33 towards the winding shaft 25 during the winding process. The spring 31 is disposed between the heavy impact block 33 and the spring support 39. The spring 31 moves towards the spring support 39 with the heavy impact block 33. The spring support 39 is fixedly disposed in the spring housing 32 and limits the deformation of the spring. The pulling force of the flexible connecting component 26 causes the spring 31 to begin to compress and deform between the heavy impact block 33 and the spring support 39, accumulating elastic potential energy.

[0076] When the incomplete gear 24 rotates to engage with the smooth portion 241 of the complete gear 27, the incomplete gear 24 and the complete gear 27 disengage from the transmission, and the winding shaft 25 and the heavy impact block 33 lose their drive. At this time, the compressed spring 31 begins to recover and instantaneously releases the stored elastic potential energy. The spring 31 exerts an instantaneous force on the heavy impact block 33, causing the heavy impact block 33 to move due to the elastic potential energy and impact the spring housing 32. Specifically, the spring 31 pushes the heavy impact block 33 to move away from the spring support 39 and impacts the base 38. This utility model connects the base 38 to the overhead power transmission line or railway contact network. The released elastic potential energy exerts a thrust on the base 38, causing the overhead power transmission line or railway contact network to vibrate, achieving the effect of anti-icing or de-icing.

[0077] like Figure 9 As shown, a winding wheel 28 is fixedly mounted on the winding shaft 25. One end of the flexible connecting component 26 is fixed to the winding wheel 28. By rotating the winding shaft 25, the winding wheel 28 is driven to rotate, and the flexible connecting component 26 is wound onto the winding wheel 28. By setting the winding wheel 28, the winding position of the flexible connecting component 26 can be restricted to the winding wheel, reducing the shear force experienced by the flexible connecting component 26 when winding on the winding shaft 25. At the same time, the winding diameter of the flexible connecting component 26 is increased by winding on the winding wheel 28, reducing the required length of the flexible connecting component 26, thereby reducing the length of the spring housing 32 and contributing to the overall weight reduction of the equipment.

[0078] like Figure 10 As shown, two winding wheels 28 are symmetrically arranged on the shaft of the winding shaft 25, namely the first winding wheel 281 and the second winding wheel 282. At the same time, two flexible connecting parts 26 are correspondingly arranged, namely the first flexible connecting part 261 and the second flexible connecting part 262, and the two are of the same length. By means of arrangement, one end of the first flexible connecting part 261 is fixed to the first winding wheel 281, and the other end is fixedly connected to the heavy impact block 33; one end of the second flexible connecting part 262 is fixed to the second winding wheel 282, and the other end is fixedly connected to the heavy impact block 33.

[0079] When the tooth portion 242 of the incomplete gear 24 meshes with the complete gear 27, the winding shaft 25 starts to rotate after receiving the power or torque transmitted by the motor 11. When the winding shaft 25 rotates, it drives the first winding wheel 281 and the second winding wheel 282 to rotate accordingly, thereby causing the first flexible connecting component 261 and the second flexible connecting component 262 to wind onto the first winding wheel 281 and the second winding wheel 282. During the winding process, the first flexible connecting component 261 and the second flexible connecting component 262 simultaneously pull the heavy impact block 33 to move towards the winding shaft 25. While the heavy impact block 33 moves, it compresses the spring 31, causing the spring 31 to deform and accumulate elastic potential energy.

[0080] When the incomplete gear 24 rotates to the point where the smooth part 241 engages with the complete gear 27, the incomplete gear 24 disengages from the complete gear 27. At this point, the winding shaft 25 can no longer receive the power or torque transmitted by the motor 11. The spring 31 is no longer under force and stops compressing, beginning to recover its deformation and release its elastic potential energy. When the spring 31 recovers its deformation and releases its elastic potential energy, it generates an instantaneous thrust on the weight impact block 33 connected to it. Under the action of the instantaneous thrust, the weight impact block 33 moves rapidly, impacting the spring housing 32 and causing it to vibrate.

[0081] Furthermore, such as Figure 11 As shown, a first winding wheel 281 and a second winding wheel 282 are arranged on the winding shaft 25, and a flexible connecting member 26 is also provided. The flexible connecting member 26 is symmetrically wound around the first winding wheel 281 and the second winding wheel 282, and through holes are respectively provided on the opposite sides of the first winding wheel 281 and the second winding wheel 282. The two ends of the flexible connecting member 26 are connected to the heavy impact block 33 according to the aforementioned embodiment, and the flexible connecting member 26 passes through the through holes. With the arrangement of this embodiment, it can be ensured that the tension of the two ends of the flexible connecting member 26 on the heavy impact block 33 remains balanced at all times during the winding process.

[0082] The disclosed solution of this utility model is an assembly structure applicable to an overhead line mechanical de-icing device. After receiving electrical energy through the motor 11, it outputs power or torque, and transmits the output power or torque to the rack 34 through the multi-stage reduction mechanism 13, worm 23, worm wheel 22, and incomplete gear 24. When the toothed portion 242 of the incomplete gear 24 engages with the rack 34, the incomplete gear 24 drives the rack 34 to displace relative to the spring housing 32. During the displacement of the rack 34 relative to the spring housing 32, the spring 31 is deformed and accumulates elastic potential energy. When the incomplete gear 24 rotates to the point where its smooth portion 241 engages with the rack 34, the transmission engagement between the incomplete gear 24 and the rack 34 is disengaged, and the rack 34 no longer displaces relative to the spring housing 32. The spring 31 recovers its deformation and releases elastic potential energy. The elastic potential energy released by the spring 31 acts on the rack 34, causing the rack 34 to undergo variable acceleration motion. When the rack 34 undergoes variable acceleration motion and comes into contact with other components, it will cause those components to vibrate. Based on this, such as Figure 13 and Figure 14 As shown, this utility model connects the ice-breaking head 81, which directly contacts the overhead line conductor or ground wire for ice breaking, to the spring housing 32. Specifically, the assembly structure also includes the ice-breaking head 81; wherein, the ice-breaking head 81 is connected to the spring housing 32; the assembly structure is placed close to the overhead line conductor or ground wire to be de-iced, and the ice-breaking head 81 abuts against the overhead line conductor or ground wire to be de-iced; when the spring 31 releases its elastic potential energy, the elastic potential energy drives the rack 34 to move and impact the spring housing 32, thereby causing the ice-breaking head 81 provided on the spring housing 32 to impact the overhead line conductor or ground wire to be de-iced for ice breaking.

[0083] in Figure 13 The bottom opening of the spring housing 32, which serves as the outer slide tube, allows the rack 34 to extend to the outside of the spring housing 32. An ice-breaking head 81 is fixedly installed at the end of the rack 34 extending outside the spring housing 32. When the mechanical vibration mechanism vibrates, the ice-breaking head 81 directly impacts the overhead line conductor or ground wire, thus removing ice from the overhead line conductor or ground wire. Figure 14 The ice-breaking head 81 is then fixedly installed in conjunction with... Figure 13 At the other end of the opposite rack 34, the direction of motor movement is controlled to move the rack 34 into the spring housing 32 and compress the spring 31. When the incomplete gear 24 and the rack 34 disengage from the transmission, the spring 31 releases its elastic potential energy, causing the rack 34 to move away from the spring housing 32 with variable acceleration, which drives the ice-breaking head 81 to directly hit the overhead line conductor or ground wire, thereby achieving the de-icing action on the overhead line conductor or ground wire.

[0084] Optionally, a limiting rod 82 is provided on the end face of the icebreaker head 81 that contacts the overhead line conductor or ground wire to limit the contact between the icebreaker head 81 and the overhead line conductor or ground wire. Further optionally, three limiting rods 82 can be provided, evenly fixed on the icebreaking end face of the icebreaker head 81. The icebreaking end face of the icebreaker head 81 can be configured as a flat surface, a curved surface, or other suitable surface structure as needed.

[0085] like Figure 13 and 14 As shown, when the ice-breaking head 81 is set at the first end 341 of the rack 34, the ice-breaking head 81 is connected to the spring housing 32 through the rack 34, and the first end 341 of the rack 34 passes through the gearbox housing 21 and extends to the outside of the gearbox housing 21. When the ice-breaking head 81 is set at the second end 342 of the rack 34, the ice-breaking head 81 is connected to the spring housing 32 through the rack 34. A through hole 321 is provided at the bottom of the spring housing 32, and the second end 342 of the rack 34 extends to the outside of the spring housing 32 through the through hole 321.

[0086] like Figure 15 As shown, when the ice-breaking head 81 is set at the second end 342 of the rack 34, the second end 342 of the rack 34 is fixedly connected to one end of the impact rod 343, and the other end of the impact rod 343 is connected to the ice-breaking head 81.

[0087] Optionally, an extension sleeve 344 is connected to the bottom of the spring housing 32; The impact rod 343 includes an impact block 3431 and a connecting rod 3432. The impact block 3431 is disposed in the spring housing 32. One end of the connecting rod 3432 is fixedly connected to the impact block 3431, and the other end passes through the extension sleeve 344, extends to the outside, and is connected to the ice-breaking head 81. At this time, the ice-breaking head 81 is connected to the spring housing 32 through the impact rod 343 and the extension sleeve 344. When the spring 31 releases its elastic potential energy, the elastic potential energy is converted into the kinetic energy of the rack 34, causing the rack 34 to accelerate towards the bottom of the spring housing 32. Specifically, when it makes variable acceleration motion, it strikes the impact block 3431. The connecting rod 3432 connected to the impact block 3431 drives the ice-breaking head 81 to strike the overhead line conductor or ground wire to be de-iced for de-icing.

[0088] Unlike existing technologies, the assembly structure of this utility model, applicable to mechanical de-icing devices for overhead power lines, includes a motor structure component, a gearbox structure component, and a spring structure component; the motor structure component and the spring structure component are fixedly mounted on the gearbox structure component. By including the motor structure component, different sized motor housings can be replaced, facilitating the installation of different motor models within the housing and promoting product standardization. The gearbox structure component allows for the fixed installation of the high-strength worm gear and incomplete gear structure within the gearbox housing, improving the overall integrity of the equipment and aiding in sealing and lubrication. The spring structure component allows for the replacement of spring housings of different sizes to match different spring models, facilitating spring selection and promoting product standardization. The assembly structure of this application features a reasonable layout, compact connections, light weight, and high transmission efficiency, effectively meeting the practical operational needs of anti-icing and de-icing devices.
