Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of deicing and defrosting of power grid equipment, and particularly relates to a self-adaptive adjustment type deicing and defrosting device for outdoor equipment of a power grid. BACKGROUND

[0002] A cable is a core basic element of modern outdoor power grid equipment, and is not only a simple wire, but also a lifeline for efficient, safe and reliable operation of the entire power system.

[0003] In a cold and humid winter or a high-altitude area, ice and snow are easily accumulated on the surface of a power transmission cable. The ice and snow layer not only significantly increases the load of the cable, causes excessive sag and arc drop change, but also may cause line dancing, insulator flashover, and even serious accidents such as cable rupture and tower collapse, thereby greatly threatening the stable operation of the power grid. Therefore, a deicing and defrosting device is needed to clean the ice and snow layer on the surface of the power transmission cable to ensure the safe use of the cable.

[0004] For example, a high-voltage cable automatic deicing detection robot disclosed in CN111900688A moves along the cable through walking wheels and uses a rotating ice-breaking knife to deice.

[0005] The above patent can realize automatic deicing along the cable, and to a certain extent, reduces the risk of manual high-altitude operation. However, the ice-breaking mode of the above patent is relatively single, the ice-breaking force is fixed, and the ice-breaking force cannot be dynamically adjusted according to the change of the ice layer thickness. In the face of uneven ice or thick ice layer, the efficiency may be insufficient or there may be a risk of damaging the cable. At the same time, the clamping and walking mechanism may slip or be stuck under extreme icing conditions, and the adaptability needs to be improved. SUMMARY

[0006] The purpose of the present application is to provide a self-adaptive adjustment type deicing and defrosting device for outdoor equipment of a power grid. The present application aims to solve the problems raised in the background art.

[0007] To achieve the above-mentioned purpose, the present application provides the following technical solutions: A self-adaptive adjustment type deicing and defrosting device for outdoor equipment of a power grid, comprising: a frame body; A clamping mechanism, a total of two groups, is arranged on the frame body, and is used to clamp the cable and deice the surface of the cable; An ice-breaking mechanism is arranged on the frame body, and is used to break ice on the surface of the cable and to self-adaptively adjust the ice-breaking force according to the thickness of the ice layer on the surface of the cable; and an installation mechanism is arranged on the frame body, and is used to realize the installation connection of the frame body.

[0008] As a preferred embodiment of the present application, each group of the clamping mechanism comprises: a mounting seat; The clamping assembly is arranged on the mounting base and used to clamp and de-ice the cable.

[0009] As a preferred scheme of the present application, the mounting base is fixedly connected to the outer wall of the frame body, and the mounting base is provided with a limiting groove. The clamping assembly comprises a limiting strip and a clamping frame. The clamping assembly comprises a limiting strip and a clamping frame.

[0010] As a preferred scheme of the present application, the clamping frame, the upper de-icing clamping plate and the lower de-icing clamping plate are provided with notches on one side. The driving assembly further comprises a servo motor, which is fixedly arranged on one side of the clamping frame.

[0011] As a preferred scheme of the present application, the ice-breaking mechanism comprises a fixed plate. The ice-breaking assembly is arranged on the fixed plate and used to break ice.

[0012] As a preferred scheme of the present application, the ice-breaking mechanism comprises a fixed plate. The ice-breaking assembly comprises an ice-breaking arm.

[0013] As a preferred embodiment of the present invention, the adjustment assembly further includes two mounting plates, each of which is fixedly connected to the outer wall of the corresponding clamping frame. A sensor is installed on one side of the outer wall of each mounting plate, and the sensor is connected to an external PLC controller to achieve wireless communication.

[0014] As a preferred embodiment of the present invention, a U-shaped plate is fixedly installed between the outer walls of the two fixed plates, and a vibration motor is installed between the outer walls of the U-shaped plate.

[0015] As a preferred embodiment of the present invention, the installation mechanism includes multiple connecting plates, each of which is fixedly connected to the outer wall of the frame, and each of the connecting plates is movably fitted with a threaded rod on its outer wall, and each of the threaded rods is fixedly connected to a positioning plate at its top end.

[0016] As a preferred embodiment of the present invention, each threaded rod has two adjusting nuts threadedly fitted on its outer surface, and the two adjusting nuts on each threaded rod are respectively located on both sides of the corresponding connecting plate.

[0017] Beneficial effects: Compared with the prior art, the present invention provides an adaptive adjustment type of outdoor power grid equipment defrosting device, which has the following beneficial effects: 1. This invention uses sensors mounted on the clamping frame to sense the thickness of the ice layer on the cable surface and the displacement changes of the clamping frame caused by icing in real time. The signals are fed back to an external PLC controller, which intelligently adjusts the downward pressure and speed of the cylinder in the ice-breaking mechanism, thereby changing the impact force of the ice-breaking hammer on the ice layer. This achieves adaptive adjustment of "heavy blows on thick ice and light taps on thin ice," ensuring the ice-breaking effect while minimizing potential mechanical damage to the cable body, thus achieving the dual goals of efficient de-icing and cable protection.

[0018] 2. This invention integrates cable clamping and surface defrosting functions into a clamping mechanism. A servo motor drives the mounting shaft and the lower de-icing clamp to rotate, and a gear set and transmission belt synchronously drive the two upper de-icing clamps to rotate in opposite directions. This allows the upper and lower de-icing clamps to close and clamp the cable while the concave structure on their surfaces can scrape and crush the thinner layer of frost, achieving preliminary cleaning of the cable. This creates conditions for the subsequent ice-breaking mechanism to handle thick ice layers, improving the overall de-icing efficiency.

[0019] 3. In this invention, the ice-breaking mechanism not only has a "hammering" ice-breaking mode that drives the ice-breaking arm to swing through a cylinder, but also integrates a vibration motor. The vibration motor can drive the entire ice-breaking hammer assembly to generate high-frequency micro-amplitude vibration. This mode is particularly suitable for brittle ice layers or cleaning residual ice after de-icing, and can effectively shake off ice fragments with strong adhesion. The two ice-breaking modes can be used alone or in combination, which greatly enhances the device's ability to cope with ice layers with different physical properties.

[0020] 4. The present invention can connect the frame to the drone through the installation mechanism. The installation mechanism adopts a threaded rod and adjusting nut to facilitate the adjustment of the distance between the device and the drone, ensuring the safety of the drone. At the same time, the installation height and horizontal position of the entire device can be flexibly adjusted according to the specific dimensions of the pole crossarm or other support structure on site, ensuring that the clamping mechanism is aligned with the cable. This design improves the versatility of the device and the convenience of on-site installation. Attached Figure Description

[0023] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0024] Example: Please refer to Figures 1 to 10 The present invention provides the following technical solutions: An adaptive adjustment type outdoor power grid equipment de-icing device comprises a frame 1, a clamping mechanism, an ice-breaking mechanism, and an installation mechanism. The clamping mechanism, ice-breaking mechanism, and installation mechanism are all mounted on the frame, as described in detail below: Please see Figure 1 , Figures 3 to 5 as well as Figure 7 and Figure 8 The frame 1 is equipped with two sets of clamping mechanisms for cable clamping and de-icing of the cable surface. Each clamping mechanism consists of a mounting base 2, a clamping assembly, and a drive assembly, as described in detail below: The mounting base 2 is fixedly connected to the outer wall of the frame 1, and a limiting groove is provided on the outer wall of the mounting base 2; The clamping assembly is mounted on the mounting base 2 and is used to clamp and de-ice the cable. Specifically, the clamping assembly includes a limiting strip 3 and a clamping frame 4. The limiting strip 3 is slidably embedded between the inner walls of the limiting groove. The clamping frame 4 is fixedly mounted on one end of the limiting strip 3. Two short shafts 5 and a mounting shaft 6 are rotatably embedded between the inner walls of the clamping frame 4. An upper de-icing clamp 7 is fixedly sleeved on the outer surface of each short shaft 5, and a lower de-icing clamp 8 is fixedly sleeved on the outer surface of the mounting shaft 6. The drive assembly is mounted on the clamping assembly and is used to drive the clamping assembly to work. Specifically, the drive assembly includes an electric push rod 9 and a transmission rod 10. The electric push rod 9 is fixedly installed on the outer wall of the mounting base 2, and the telescopic end of the electric push rod 9 is fixedly connected to the outer wall of the clamping frame 4. The transmission rod 10 is rotatably connected between the inner wall of the clamping frame 4. Gears 11 are fixedly sleeved on the outer surface of both the transmission rod 10 and the mounting shaft 6, and the two gears 11 mesh. The transmission rod 10 is connected to the two end shafts through two sets of transmission wheels and transmission belts respectively.

[0025] In this embodiment, the outer wall of the clamping frame 4 in the clamping assembly is recessed to prevent it from obstructing the use of the ice-breaking mechanism. The clamping frame 4 slides in conjunction with the limiting groove on the mounting base 2 via the limiting strip 3, ensuring that the clamping frame 4 can only move along a preset straight path, preventing deflection or shaking during clamping. The lower end of the limiting groove extends inward to prevent the limiting strip 3 from falling off. The electric push rod 9 serves as a linear drive source, and its telescopic end is directly connected to the clamping frame 4, providing the direct and stable driving force required for clamping and releasing. It also facilitates adjusting the distance between the two clamping frames 4 according to the diameter of the cable to be de-iced. The short shaft 5 is rotatably mounted on both sides of the clamping frame 4. The inner side wall, and one end of the short shaft 5 passes through the outer side wall of the clamping frame 4 and extends to its outer side for a certain distance, which facilitates the installation of the upper de-icing clamp 7. The outer side wall of the upper de-icing clamp 7 is flush with the recessed surface of the clamping frame 4 to avoid the upper de-icing clamp 7 affecting the use of the ice-breaking mechanism. The mounting shaft 6 in the drive assembly cooperates with the gear 11 to drive the transmission rod 10 to rotate. Since the transmission rod 10 is connected to the two short shafts 5 through two sets of transmission wheels and transmission belts respectively, it is convenient to drive the corresponding two short shafts 5 to rotate, thereby driving the upper de-icing clamp 7 and the lower de-icing clamp 8 to rotate synchronously and in opposite directions, which facilitates the clamping and fixing of the cable for the subsequent use of the ice-breaking mechanism.

[0026] Please see Figure 1 , Figure 3 as well as Figure 7 The clamping frame 4, the upper de-icing clamp 7, and the lower de-icing clamp 8 all have notches 12 on one side of their outer walls; The drive assembly also includes a servo motor 13, which is fixedly installed on the inner wall of one side of the clamping frame 4. The output end of the servo motor 13 is fixedly connected to one end of the mounting shaft 6.

[0027] In this embodiment, the notch 12 is arc-shaped, which facilitates a better fit to the cable shape. The drone drives the frame 1 and the clamping mechanism to move on the cable. With the help of the notch 12, it can scrape and crush the thinner layer of frost, realizing the initial cleaning of the cable. This creates conditions for the subsequent ice-breaking mechanism to handle the thick ice layer, improving the overall de-icing efficiency. The servo motor 13 can easily drive the mounting shaft 6 to rotate, which in turn drives the clamping assembly to work, improving the ease of use of the clamping mechanism.

[0028] Please see Figures 1 to 3 and Figures 6 to 10 An ice-breaking mechanism is provided on the frame 1 to break ice on the cable surface and to adaptively adjust the ice-breaking force according to the thickness of the ice layer on the cable surface. The ice-breaking mechanism consists of a fixed plate 14, an ice-breaking component, and an adjustment component, as described in detail below: There are two fixing plates 14, and each fixing plate 14 is fixedly connected to the bottom of the frame 1; The ice-breaking assembly is set on the fixed plate 14 and is used to break ice. Specifically, the ice-breaking assembly includes ice-breaking arms 15. There are two ice-breaking arms 15. Each ice-breaking arm 15 is rotatably embedded between the outer walls of the two fixed plates 14. An ice-breaking hammer 16 is fixedly connected to one end of each ice-breaking arm 15. Multiple impact protrusions 17 are fixedly connected to the outer surface of each ice-breaking hammer 16. A strip-shaped limiting groove is opened on the outer wall of each ice-breaking arm 15. An adjustment component is set on the ice-breaking component and the clamping frame 4. It is used to realize the adaptive adjustment of the ice-breaking force of the ice-breaking component. Specifically, the adjustment component includes a cylinder 18, which is fixedly installed on the top of the frame 1. A buffer connector 19 is fixedly installed on the output end of the cylinder 18. Two connecting strips 20 are fixedly installed on the bottom of the buffer connector 19. Two limiting rods 21 are fixedly connected between the outer walls of the two connecting strips 20, and each limiting rod 21 is slidably embedded in the corresponding strip-shaped limiting groove.

[0029] In this embodiment, the telescopic end of the cylinder 18 is located between two fixed plates 14, which provide a certain degree of protection. The cylinder 18 facilitates the lifting and lowering of the two connecting bars 20. Combined with the limiting rod 21 and the corresponding strip-shaped limiting groove, it facilitates the reciprocating swing of the two ice-breaking arms 15, striking the ice layer on the cable surface between the clamping components. The vertically downward thrust provided by the cylinder 18 is converted into the rotational motion of the ice-breaking arm 15 around the fulcrum, generating an amplified impact force perpendicular to the cable surface at the end of the ice-breaking hammer 16. This allows a relatively small cylinder output force to achieve a powerful ice-breaking impact, improving energy utilization efficiency and enabling… The impact force is more concentrated on the ice layer. The telescopic end of the cylinder 18 is connected by a buffer connector 19 and two connecting strips 20. The buffer connector 19 can effectively absorb and attenuate the impact energy generated when the ice-breaking arm 15 and the ice-breaking hammer 16 hit the ice layer, preventing it from being directly transmitted back to the cylinder 18 and the frame 1, protecting the core drive components, and extending the service life of the device. At the same time, it allows the ice-breaking hammer 16 to have a certain "soft landing" effect when it contacts the ice layer, avoiding potential damage to the cable caused by rigid collision. The multiple impact protrusions 17 on the outer surface of the ice-breaking hammer 16 disperse the concentrated impact force to multiple points, making it easier to crack and pulverize the ice layer, which is more efficient than a flat striking surface.

[0030] Please see Figure 7 and Figure 8 The adjustment assembly also includes two mounting plates 22, each of which is fixedly connected to the outer wall of the corresponding clamping frame 4. A sensor 23 is installed on one side of the outer wall of each mounting plate 22. The sensor 23 is connected to an external PLC controller to achieve wireless communication.

[0031] In this embodiment, the mounting plate 22 is located in the recess of the clamping frame 4, providing stable support and protection for the sensor 23. The two sensors 23 are a displacement sensor and an ultrasonic sensor, respectively. Both displacement sensors and ultrasonic sensors are existing technologies and will not be described in detail here. The two types of sensors 23 can conveniently sense the thickness of the ice layer on the cable surface and the displacement changes of the clamping frame 4 caused by icing in real time, and feed the signals back to the external PLC controller. The controller intelligently adjusts the downward pressure and speed of the cylinder 18 in the ice-breaking mechanism, thereby changing the impact force of the ice-breaking hammer 16 on the ice layer, realizing the adaptive adjustment of "heavy blows on thick ice and light taps on thin ice". While ensuring the ice-breaking effect, it minimizes the potential mechanical damage to the cable body, achieving the dual goals of efficient de-icing and cable protection.

[0032] Please see Figure 3 , Figure 9 and Figure 10 A U-shaped plate 24 is fixedly installed between the outer walls of the two fixed plates 14, and a vibration motor 25 is installed between the outer walls of the U-shaped plate 24.

[0033] In this embodiment, the opening of the U-shaped plate 24 faces the direction of the cylinder 18, which facilitates the protection of the bottom of the vibration motor 25, preventing it from being damaged by collision with debris and improving its safety. When the ice-breaking component comes into contact with the cable, the vibration motor 25 can drive the entire ice-breaking hammer component to generate high-frequency micro-amplitude vibration, which can effectively shake off ice fragments with strong adhesion and improve the use effect of the ice-breaking component.

[0034] Please see Figure 1 , Figure 3 and Figure 4 An installation mechanism is provided on frame 1 to realize the installation and connection of frame 1, as described in detail below: The installation mechanism includes multiple connecting plates 26, each connecting plate 26 is fixedly connected to the outer wall of the frame 1, and each connecting plate 26 is movably embedded with a threaded hanger 27 on its outer wall, and a positioning plate 28 is fixedly connected to the top of each threaded hanger 27. Each threaded rod 27 has two adjusting nuts 29 threadedly fitted on its outer surface, and the two adjusting nuts 29 on each threaded rod 27 are located on both sides of the corresponding connecting plate 26.

[0035] In this embodiment, the positioning plate 28 facilitates the installation of the threaded rod 27 onto the drone, the crossarm of the on-site tower, or other supporting structures. The connecting plate 26 and the frame 1 are integrally connected, improving the stability of the installation mechanism. The connecting plate 26 is slidably sleeved on the surface of the corresponding threaded rod 27, facilitating the adjustment of the distance between the frame 1 and the drone, ensuring safety when used with the drone, and allowing for flexible adjustment of its installation height and horizontal position to ensure alignment of the clamping mechanism and the cable. The adjusting nuts 29 on the upper and lower surfaces of the connecting plate 26 facilitate the fixing of the connecting plate 26 and the frame 1.

[0036] Working principle: When in use, install the positioning plate 28 on the drone, the crossarm of the on-site tower or other support structure, tighten the adjusting nut 29 on the top of the connecting plate 26 to the corresponding threaded rod 27 in advance, and put the connecting sleeve on the frame 1 onto the surface of the corresponding threaded rod 27. Adjust the height to a suitable position, and then tighten the adjusting nut 29 on the bottom of the connecting plate 26 to ensure that the notches of the clamping frames 4 of the two clamping mechanisms are aligned with the target cable, thus completing the installation of the frame 1; The electric push rod 9 of the clamping mechanism is activated, which pushes the clamping frame 4 (guided by the limiting strip 3) to move towards the cable until the cable enters the recessed area between the two clamping frames 4. The servo motor 13 works, driving the lower de-icing clamp 8 to rotate, and through the gear, transmission belt and transmission wheel structure, it drives the two upper de-icing clamps 7 to rotate in the opposite direction, thus completing the clamping of the cable. The drone drives the frame 1 and the clamping mechanism to move along the cable, which can scrape off the soft frost on the surface of the cable. When the ice layer thickness is detected, the two sensors 23 installed on the clamping frame 4 start to work. The ultrasonic sensor emits ultrasonic waves to the cable, measures the time it takes for the sound wave to reflect back from the sensor to the ice layer surface, and calculates the thickness of the ice layer in the measurement direction by comparing the distance difference when there is no ice and when there is ice. The clamping frame 4 is closed under the drive of the electric push rod 9. The displacement sensor detects the change in displacement difference based on the stroke required for the clamping frame 4 to move when it contacts the cable body, and calculates the ice layer thickness. If sensor 23 detects that the ice layer is very thick, sensor 23 transmits the detected signal to the external PLC controller. The controller instructs the cylinder 18 of the ice-breaking mechanism to push out with greater pressure. The force of cylinder 18 is transmitted to the strip-shaped limiting groove of ice-breaking arm 15 through buffer connector 19, connecting bar 20 and limiting short rod 21. As the limiting short rod 21 slides in the groove and pushes the groove wall, it forces the two ice-breaking arms 15 to swing downward rapidly around the hinge point with the fixed plate 14, thereby driving the ice-breaking hammer 16 and the impact protrusion 17 to violently strike the thick ice layer under the cable with greater kinetic energy. Buffer connector 19 absorbs part of the impact reaction force in this process to protect cylinder 18. If sensor 23 detects that the ice layer is thin, the PLC controller instructs cylinder 18 to work with less pressure, so that ice-breaking hammer 16 can strike with less force. In addition, during the entire ice-breaking process or after the thick ice is broken, vibration motor 25 can be started to transmit vibration to ice-breaking arm 15 and ice-breaking hammer 16 through U-shaped plate 24. High-frequency vibration is used to shake off the remaining ice fragments, so that the cable surface is cleaned more thoroughly.

[0037] Finally, it should be noted that the above descriptions are merely preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
