Description

Technical Field

[0001] The present invention relates to the field of power transmission and transformation maintenance equipment, and particularly to a vibration-type intelligent ice removal system for fixed installation of transmission wires without maintenance. Background Art

[0002] In power transmission and transformation projects, the phenomenon of wire icing is a common and intractable problem, seriously threatening the stable operation of the power system. The formation of ice is affected by various factors, including the structural characteristics of the wire, environmental temperature, supercooled water droplets in the air, and wind speed. This phenomenon not only damages the mechanical properties of the transmission line, but may also cause safety hazards such as conductor galloping, tower deformation or collapse, and even wire breakage and insulator flashover, leading to major accidents.

[0003] In some parts of our country, especially in alpine mountainous areas and humid environments, they have long been troubled by ice disaster problems. This phenomenon not only leads to frequent failures of power grid equipment, but also often causes traffic blockage and difficult emergency repairs due to bad weather, thus aggravating the impact of the disaster. Historically, many severe ice and snow weather events have caused power outages, resulting in social and economic losses and repair pressure.

[0004] Existing ice removal technologies can be classified into thermal ice melting method, mechanical ice breaking method, natural passive method and other comprehensive methods. Among them, the thermal ice melting method relies on current heating to melt the ice on the wire. Although the effect is obvious, there are problems such as large equipment investment, high energy consumption and the need for power outage operation, which limit its practical application. In contrast, the mechanical ice breaking method removes ice through external force, which is relatively energy-saving, but its efficiency is low, and the difficulty increases significantly when operating in complex terrains or remote areas. Common mechanical ice removal methods include throwing ropes for friction, hitting with sticks, and scraping with pulleys, etc., all of which are restricted by the use environment and operation cost. As a new application in the field of mechanical ice removal, the wire robot can move along the wire driven by a battery and perform ice removal tasks. However, this technology still has many problems: limited by battery power supply, its endurance and load-bearing capacity are insufficient, the moving resistance is too large and the efficiency is low when facing thicker ice layers, so it is difficult to be widely promoted.

[0005] In summary, most of the current mobile ice removal devices and technologies, including thermal ice melting method, mechanical ice breaking method and wire robots, are faced with challenges such as high energy consumption, limited efficiency and poor adaptability, especially limited application in remote or harsh environments. Therefore, there is an urgent need for a fixed ice removal device that can operate stably for a long time, without maintenance and with simple operation, so as to improve the ice removal efficiency and ensure the safe operation of the transmission line. Summary of the Invention

[0006] To solve the deficiencies of the prior art, the purpose of the present invention is to provide a fixed-installation, maintenance-free, vibration-type intelligent ice removal system for transmission wires. By adopting this solution, vibration ice removal can be achieved through the conversion of elastic potential energy into high-speed impact, and it has a high degree of automation. By automatically starting ice removal, the effect of intelligent ice removal without manual intervention can be achieved.

[0007] The present invention is realized through the following technical solutions:

[0008] A fixed-installation, maintenance-free, vibration-type intelligent ice removal system for transmission wires, including an ice removal module;

[0009] The ice removal module includes:

[0010] A housing, which is fixed on the transmission wire, and a chamber is provided inside the housing;

[0011] An impactor, which is located inside the chamber. The impactor includes an impact head and a clamping assembly; the impact head is located at one end of the chamber close to the transmission wire, and the impact head is connected to the other end of the chamber through an elastic telescopic member, and the elastic telescopic member can expand and contract in a direction away from or close to the transmission wire; the clamping assembly is located on the side of the impact head away from the transmission wire and is used for clamping or releasing the impact head;

[0012] A driving unit, which is used to drive the clamping assembly to move in a direction away from or close to the transmission wire.

[0013] Compared with most of the existing mobile de-icing devices and technologies, which face challenges such as high energy consumption, limited efficiency, and poor adaptability, especially being restricted in application in remote or harsh environments, the present invention provides a fixed-installation and maintenance-free vibration-type intelligent de-icing system for transmission wires. By adopting this solution, vibration de-icing can be achieved through the conversion of elastic potential energy into high-speed impact, and it has a high degree of automation. By automatically starting de-icing, the effect of intelligent de-icing without manual intervention can be achieved. In a specific solution, it includes a de-icing module fixed on the transmission wire. The de-icing module can be fixed through a wire fixing module. For example, the wire fixing module can adopt an opening and closing type buckle. The transmission wire is buckled inside through the opening and closing type buckle to realize the hoisting and fixing of the de-icing module. The de-icing module includes a housing, an impactor, and a driving unit. The top of the housing is fixed on the transmission wire through the wire fixing module, and the inner chamber of the housing is used to accommodate the impactor and the driving unit. When de-icing is required on the transmission wire, the driving unit is controlled to drive the clamping component to move towards the impact head until the clamping component clamps the impact head. Subsequently, the driving unit is controlled to drive the clamping component to move in the reverse direction, thereby driving the impact head to move synchronously, causing the impact head to compress the elastic telescopic member. When reaching the specified position, the clamping component releases the impact head at this time, and the impact head realizes high-speed movement under the elastic potential energy of the elastic telescopic member, thereby impacting the end of the housing. In this way, the housing and the transmission wire can be driven to vibrate violently and oscillate up and down through the impact, so that the ice and snow on the transmission wire are forced to fall off, achieving the purpose of de-icing.

[0014] Furthermore, as a specific structure of the clamping component, the clamping component includes:

[0015] A base;

[0016] A gripper component, the gripper component includes two claws respectively arranged on both sides of the base. The middle of the claw is hinged to the base. The end of the claw facing the impact head is the clamping end. The clamping ends of the two claws are used to clamp or release the impact head towards each other;

[0017] A first driving member, the first driving member is used to drive the clamping ends of the two claws to approach each other;

[0018] A second driving member, the second driving member is used to drive the other ends of the two claws to approach each other; In this solution, the middles of the two claws are hinged to both sides of the base. In this way, when the clamping ends of the two claws approach each other driven by the first driving member, while clamping the impact head, the other ends of the two claws move away from each other; when the other ends of the two claws approach each other driven by the second driving member, at this time, the clamping ends of the two claws move away from each other, thereby releasing the impact head; In this way, through the separate control of the first driving member and the second driving member, the clamping and release of the clamping ends of the two claws can be realized.

[0019] Further, to clamp the impact head by mechanical drive to reduce energy consumption, the first driving member includes an elastic tension spring for applying a tensile force; elastic tension springs are arranged on both sides of the clamping end; connecting columns extend outward from both sides of the clamping end respectively, and both ends of the elastic tension spring are respectively connected to the connecting columns on the same side of the two clamping ends;

[0020] The bottom of the impact head is provided with a hook, and grooves for accommodating the clamping end are provided on both sides of the hook; the bottom of the hook can extend into the space between the two clamping jaws from the clamping gap between the two clamping ends; during the process of the bottom of the hook extending into the space between the two clamping jaws, both sides of the bottom of the hook can push the two clamping ends away from each other, so that the two clamping ends move away from each other. In this solution, the elastic tension spring always provides a tensile force, and the two elastic tension springs are arranged on both sides of the clamping end. While balancing the tensile force, it provides enough space for the hook to extend; during specific operation, first, the driving unit drives the base to move upward. When the bottom of the hook touches the clamping end, since the two clamping ends are arc-shaped surfaces, both sides of the bottom of the hook fall on the arc-shaped surfaces, and will gradually squeeze the two clamping ends and push the clamping ends away from each other, so as to extend into the space between the two clamping jaws. Subsequently, the two clamping ends move towards each other under the action of the elastic tension spring to be clamped into the grooves on both sides of the hook, so as to realize the clamping of the impact head.

[0021] Further, to release the impact head by mechanical drive to reduce energy consumption, the second driving member includes a trigger fixed to the other end of the chamber;

[0022] The clamping jaws are arc-shaped, and the concave surfaces of the two clamping jaws face each other;

[0023] The trigger includes an annular plate, and two opposite guiding surfaces are respectively provided on the inner side of the annular plate; when the two clamping jaws are in the clamping state, the other ends of the two clamping jaws can extend into the middle of the annular plate;

[0024] During the process of the other ends of the jaws extending into the middle of the ring plate, the guiding surfaces are all used to contact the outer walls of the jaws and gradually drive the other ends of the two jaws to approach each other, so that the clamping ends of the two jaws release the impact head. In this solution, the jaws are integrally arc-shaped, and the trigger includes a ring plate. After the jaws clamp the impact head, driven by the driving unit, the clamping assembly drives the impact head to move away from the power transmission wire, while compressing the elastic telescopic member. When the other ends of the jaws contact the ring plate, at this time, the outer walls of the other ends of the jaws contact the guiding surfaces, and under the guidance of the guiding surfaces and the arc surfaces of the jaws themselves, the other ends of the two jaws gradually extend into the ring plate and approach each other. At this time, the clamping ends of the jaws move away from each other synchronously to realize the release of the impact head. In this way, the impact head can move at high speed under the elastic potential energy of the elastic telescopic member, so as to impact the end of the housing, drive the housing and the power transmission wire to vibrate violently and oscillate up and down at the same time, so that the ice and snow on the power transmission wire are forced to fall off, achieving the purpose of deicing.

[0025] Further, as a specific implementation manner of the hinge, both sides of the base are provided with notches for partially accommodating the jaws. Both sides of the notches are provided with ear plates, and bearings are provided on the ear plates. Both sides of the jaws are rotatably connected to the ear plates through the bearings.

[0026] Further, to raise the ring plate so that there is enough space for the other ends of the jaws to extend into the bottom of the ring plate, the ring plate is connected to the other end of the chamber through a plurality of support rods. Among them, the ring plate can be supported and fixed respectively by the first support rod and the second support rod on both sides of the bottom of the ring plate.

[0027] Further, as a specific structure of the driving unit, the driving unit includes a rotating motor and a plurality of guide rods;

[0028] The rotating motor is fixed to the other end of the chamber; a lead screw is provided at the output end of the rotating motor, and the lead screw is threadedly connected to the clamping assembly;

[0029] One ends of a plurality of the guide rods are fixed to the other end of the chamber, and the other ends of the plurality of guide rods sequentially pass through the clamping assembly and the impact head, and are all slidably connected to the clamping assembly and the impact head. The guide rods and the lead screw are parallel to each other. In this solution, a long strip can be provided in the middle of the base, and a threaded through hole can be opened on the long strip to facilitate threaded connection with the lead screw. Driven by the rotating motor, the lead screw can be controlled to rotate forward or backward to drive the clamping assembly to move up and down; while the guide rods are used to limit and guide the clamping assembly and the impact head. The impact surface of the impact head can adopt a plane to increase the oscillation range.

[0030] Further, in order to leave a displacement space for the clamping assembly, the elastic telescopic member is a strong spring, and the clamping assembly is located in the middle of the strong spring.

[0031] Further, in order to achieve self-power supply, achieve the purpose of one-time installation, long-term effectiveness and energy consumption reduction, an electric control module and an inductive power taking module are further included;

[0032] The electric control module is fixed on the housing, and the electric control module includes a power storage module for supplying power to the drive unit;

[0033] The inductive power taking module includes an open-type current transformer, the open-type current transformer is clamped on the power transmission wire, and is connected to the power storage module through a power transmission line. In this solution, the electric control module is arranged below the de-icing module, and a bracket is arranged inside the electric control module to facilitate the fixing of the power storage module. The power storage module is used to supply power to the drive motor. The power storage module is a high-weather-resistant lithium battery to ensure the stable operation of the de-icing system; a control board is driven on the power storage module, which runs the Linux system based on the ARM processor, and runs an algorithm for judging the icing risk of the power transmission and transformation wire based on multi-modal data fusion inside. It collects the temperature, humidity and wind speed information provided by the sensor module, and takes real-time pictures of the wire, inputs the algorithm to comprehensively judge the icing risk level. When the icing risk is higher than the threshold, the de-icing is automatically started to achieve the effect of intelligent de-icing without manual intervention.

[0034] The inductive power taking module includes an open-type CT current transformer. There is an alternating magnetic field around the high-voltage power transmission wire, and the magnetic field around the bus changes with the current of the high-voltage wire. Then, an induced voltage is generated through the energy harvesting coil, and the induced voltage is subjected to transformation processing through an energy harvesting power supply module such as rectification, filtering and voltage stabilization, and finally realizes power supply for the de-icing system and charging for the power storage module.

[0035] Further, for monitoring the on-site environment and the icing degree, the electronic control module further includes a sensor module. The sensor module is used to have a temperature sensor, a humidity sensor, a wind speed sensor, and a camera. The camera is used to monitor the transmission wire. In this solution, the main control module collects the current ambient temperature, humidity, wind speed, and takes a current photo of the wire through the sensor module, and inputs it into the risk judgment algorithm for icing of transmission and transformation wires based on multi-modal data fusion. The algorithm outputs the current icing probability of the wire. When the icing probability is greater than the specified threshold of 85%, the main control module controls the driving device in the de-icing module to drive the lead screw to rotate forward. At the same time, the output torque of the driving device is collected in real time through the torque sensor, driving the clamping assembly to move upward; when the clamping end of the claw contacts the bottom hook of the impact head (the output torque of the driving device is lower than the threshold), the two clamping ends can be squeezed to open outward. After continuing to move upward and crossing the hook, the clamping ends are affected by the elastic springs limited on both sides and close to achieve the locking purpose. When moving to the top, the output torque of the driving device is higher than the threshold, and the main control module controls the driving device to stop rotating forward. Then, the main control module controls the driving device to drive the lead screw to rotate reversely, driving the clamping assembly and the locked impact head to move downward, compressing the strong spring to start storing energy. Until the bottom of the claw of the clamping assembly touches the trigger, the bottom of the claw is forced to close inward, and the top, that is, the clamping end, opens outward, releasing the impact head, and the impact head is affected by the strong spring and impacts the top of the housing and the transmission wire at high speed. The transmission wire is violently vibrated and oscillated up and down by the high-speed impact, so that the ice and snow on the wire fall off by force, thus achieving the purpose of de-icing.

[0036] Compared with the prior art, the present invention has the following advantages and beneficial effects:

The illustrative embodiments of the present invention and their descriptions are only used to explain the present invention and are not used to limit the present invention.

[0048] Embodiment 1:

[0049] This Embodiment 1 provides a power transmission wire 4 fixedly installed maintenance - free vibration - type intelligent deicing system, as Figures 1-4 shown, including a deicing module 5;

[0053] A driving unit 15, the driving unit 15 is used to drive the clamping assembly 7 to move in a direction away from or close to the power transmission wire 4.

[0054] Compared with most mobile de-icing devices and technologies in the prior art, which all face challenges such as high energy consumption, limited efficiency, and poor adaptability, especially the problem of being limited in application in remote or harsh environments, the present invention provides a fixed-installation and maintenance-free vibration-type intelligent de-icing system for power transmission wires 4. Adopting this solution, it can convert elastic potential energy into high-speed impact to achieve vibration de-icing, and it has a high degree of automation. By automatically starting de-icing, the effect of intelligent de-icing without manual intervention is achieved. In a specific solution, it includes a de-icing module 5 fixed to the power transmission wire 4. The de-icing module 5 can be fixed through a wire fixing module 1. For example, the wire fixing module 1 can adopt an opening and closing type buckle or the like to buckle the power transmission wire 4 inside to realize the hoisting and fixing of the de-icing module 5. The de-icing module 5 includes a housing 9, an impactor 2, and a driving unit 15. The top of the housing 9 is fixed to the power transmission wire 4 through the wire fixing module 1, and the internal chamber of the housing 9 is used to accommodate the impactor 2 and the driving unit 15. When de-icing is required on the power transmission wire 4, control the driving unit 15 to drive the clamping assembly 7 to move towards the impact head 21 until the clamping assembly 7 clamps the impact head 21. Then control the driving unit 15 to drive the clamping assembly 7 to move in the reverse direction, thereby driving the impact head 21 to move synchronously, so that the impact head 21 compresses the elastic telescopic member 8. When reaching the specified position, at this time the clamping assembly 7 releases the impact head 21, and the impact head 21 realizes high-speed movement under the elastic potential energy of the elastic telescopic member 8, so as to impact the end of the housing 9. In this way, the housing 9 and the power transmission wire 4 can be driven to vibrate violently and oscillate up and down, so that the ice and snow on the power transmission wire 4 are forced to fall off to achieve the purpose of de-icing.

[0055] Embodiment 2:

[0060] A first driving member, the first driving member is used to drive the clamping ends of the two jaws 26 to approach each other;

[0061] A second driving member, the second driving member is used to drive the other ends of the two jaws 26 to approach each other; In this solution, the middle parts of the two jaws 26 are hinged to both sides of the base 25. In this way, when the clamping ends of the two jaws 26 approach each other driven by the first driving member, while clamping the impact head 21, the other ends of the two jaws 26 move away from each other; and when the other ends of the two jaws 26 approach each other driven by the second driving member, at this time, the clamping ends of the two jaws 26 move away from each other, thereby releasing the impact head 21; In this way, through the separate control of the first driving member and the second driving member, the clamping and releasing of the clamping ends of the two jaws 26 can be realized.

[0062] In this embodiment, in order to clamp the impact head 21 by means of mechanical drive to reduce energy consumption, the first driving member includes an elastic tension spring 23 for applying a pulling force; elastic tension springs 23 are arranged on both sides of the clamping end; connecting columns extend outwards respectively on both sides of the clamping end, and the two ends of the elastic tension spring 23 are respectively connected to the connecting columns on the same side of the two clamping ends;

[0063] The bottom of the impact head 21 is provided with a hook 22, and both sides of the hook 22 are provided with grooves for accommodating the clamping ends; the bottom of the hook 22 can extend between the two clamping claws 26 from the clamping gap between the two clamping ends; during the process of the bottom of the hook 22 extending between the two clamping claws 26, both sides of the bottom of the hook 22 can push the two clamping ends away from each other, so that the two clamping ends move away from each other. In this solution, the elastic tension springs 23 always provide tension, and the two elastic tension springs 23 are respectively arranged on both sides of the clamping end, providing sufficient space for the hook 22 to extend while balancing the tension; during specific operation, first, the driving unit 15 drives the base 25 to move upward. When the bottom of the hook 22 contacts the clamping end, since the two clamping ends are arc-shaped surfaces, the two sides of the bottom of the hook 22 fall on the arc-shaped surfaces, gradually squeezing the two clamping ends and pushing the clamping ends away from each other, so as to extend between the two clamping claws 26. Subsequently, the two clamping ends move towards each other under the action of the elastic tension springs 23 to be clamped into the grooves on both sides of the hook 22, thereby realizing the clamping of the impact head 21.

In this solution, the jaws 26 are integrally arc-shaped, and the trigger 12 includes an annular plate. After the jaws 26 clamp the impact head 21, driven by the driving unit 15, the clamping assembly 7 drives the impact head 21 to move away from the transmission wire 4, and at the same time compresses the elastic telescopic member 8. When the other end of the jaw 26 contacts the annular plate, at this time, the outer side wall of the other end of the jaw 26 contacts the guiding surface, and under the guidance of the guiding surface and the arc surface of the jaw 26 itself, the other ends of the two jaws 26 gradually extend into the annular plate and approach each other. At this time, the clamping ends of the jaws 26 move away from each other synchronously to realize the release of the impact head 21. In this way, the impact head 21 can move at high speed under the elastic potential energy of the elastic telescopic member 8, so as to impact the end of the housing 9, drive the housing 9 and the transmission wire 4 to vibrate violently and oscillate up and down at the same time, so that the ice and snow on the transmission wire 4 are stressed and fall off, achieving the purpose of deicing.

The power storage module 16 is used to supply power to the drive motor, and the power storage module 16 is a high-weather-resistance lithium battery to ensure the stable operation of the de-icing system; a control board 17 is driven on the power storage module 16, which runs a Linux system based on an ARM processor, and runs an algorithm for judging the icing risk of power transmission and transformation wires based on multi-modal data fusion inside. It collects the temperature, humidity, and wind speed information provided by the sensor module 19, and takes real-time pictures of the wires, inputs the algorithm to comprehensively judge the icing risk level. When the icing risk is higher than the threshold, the de-icing is automatically started to achieve the effect of intelligent de-icing without manual intervention.

[0080] The induction power acquisition module 3 includes an opening and closing type CT current transformer. There is an alternating magnetic field around the high-voltage transmission wire. The magnetic field around the busbar changes with the current of the high-voltage wire, and then an induced voltage is generated through the induction energy acquisition coil. The induced voltage is processed through an energy acquisition power supply module such as rectification, filtering, and voltage stabilization, and finally realizes power supply for the de-icing system and charging for the energy storage module 16.

[0081] In this embodiment, in order to monitor the on-site environment and the icing degree, the electronic control module 6 further includes a sensor module 19. The sensor module 19 is used for a temperature sensor, a humidity sensor, a wind speed sensor, and a camera. The camera is used to monitor the transmission wire 4. In this solution, the main control module collects the current ambient temperature, humidity, wind speed, and takes a current photo of the wire through the sensor module 19, and inputs it into an algorithm for judging the icing risk of the power transmission and transformation wire based on multi-modal data fusion. The algorithm outputs the current wire icing probability. When the icing probability is greater than the specified threshold of 85%, the main control module controls the driving device in the de-icing module 5 to drive the lead screw 20 to rotate forward, and at the same time, the output torque of the driving device is collected in real time through a torque sensor, driving the clamping assembly 7 to move upward; when the clamping end of the claw 26 touches the bottom hook 22 of the impact head 21 (the output torque of the driving device is lower than the threshold), the two clamping ends can be squeezed to open outward. After continuing to move upward and passing over the hook 22, the clamping ends are affected by the elastic tension springs 23 limited on both sides and close to achieve the locking purpose. When moving upward to the top, the output torque of the driving device is higher than the threshold, and the main control module controls the driving device to stop rotating forward. Then, the main control module controls the driving device to drive the lead screw 20 to rotate in reverse, driving the clamping assembly 7 and the locked impact head 21 to move downward, compressing the strong spring to start storing energy. Until the bottom of the claw 26 of the clamping assembly 7 touches the trigger 12, the bottom of the claw 26 is forced to close inward, and the top, that is, the clamping end, opens outward, releasing the impact head 21, and the impact head 21 is affected by the strong spring and impacts the top of the housing 9 and the transmission wire 4 at a high speed. The transmission wire 4 is violently vibrated and oscillated up and down by the high-speed impact, so that the ice and snow on the wire are forced to fall off, thus achieving the purpose of de-icing.
