Description

Technical Field

[0001] This utility model relates to the innovation and design of a miniature ice melter for high-voltage power lines. Background Technology

[0002] This utility model of a high-voltage line miniature de-icing device is mainly aimed at the problem of ice and snow covering the overhead contact line during severe weather such as freezing rain and blizzards, which can cause electric locomotives or EMUs to malfunction. The invention innovates and designs a high-voltage line miniature de-icing device.

[0003] Currently, the four existing de-icing methods—manual de-icing, DC de-icing, AC de-icing, and specialized de-icing devices (including de-icing robots and carbon slide de-icing)—all have a major bottleneck: de-icing affects the normal operation of trains, making railway transportation losses inevitable.

[0004] The device provided in this embodiment of the utility model can operate for a long time in a section of the overhead contact line during severe weather such as freezing rain that affects the operation of the contact line. It can autonomously and dynamically de-ic the contact line and move to the cantilever arm of the non-working support of the contact line before the train passes, so as not to affect the normal operation of the train, avoid railway ticket losses, and save a lot of de-icing costs. Summary of the Invention

[0005] The high-voltage line miniature ice melter provided in this embodiment includes an ice melter body, a cross-chord crossing section, an anchor section crossing section, a power supply and power supply module, an energy acquisition module, and an ice removal drive module. The ice melter body is used to remove the ice layer covering the contact wire through eddy current heat generated by electromagnetic induction. The cross-chord crossing section is used to connect the dropper and the positioner suspended on the contact wire. The anchor section crossing section guides the high-voltage line miniature ice melter smoothly through the contact wire anchor section joint. The power supply and power supply module stores excess energy acquired by the energy acquisition module and powers the high-voltage line miniature ice melter. All actions are powered by electricity; the power acquisition module is used to acquire electrical energy by utilizing the principle of electromagnetic induction when current flows through the contact wire. The power acquisition module is installed behind the ice-melting body in the direction of advancement, that is, it acquires electrical energy after the ice layer on the contact wire is cleared; the de-icing drive module is used to provide forward power for the high-voltage line miniature ice melter; at the same time, this utility model can also be used on various high-voltage power line equipment. Its working principle is slightly different from that on railway contact wires. It can be used on various high-voltage power line equipment simply by canceling the anchor section crossing function of the equipment and adjusting the size ratio of the equipment.

[0006] To achieve the above objectives, the embodiments of this utility model adopt the following technical methods.

[0007] This utility model addresses the problem of ice and snow accumulation on railway overhead contact lines affecting normal train operation and the significant manpower and resources required for de-icing. It discloses a miniature ice melter for high-voltage lines. Unlike the eddy current ice melt module in the applicant's patented intelligent ice melter for railway high-voltage overhead contact lines, the heat source coil of this ice melter consists of two parts that work only when combined. Furthermore, the radius of the heat source coil can be designed to be larger, increasing the device's power. Also unlike the eddy current ice melt module in the applicant's patented intelligent ice melter for railway high-voltage overhead contact lines, the heat generated by this ice melter does not need to be conducted to the ice melter ring via silicon oxide ceramic; instead, it is directly transferred to the ice layer through the ice melter core, significantly increasing heat conduction efficiency. Therefore, the ice melter of this utility model is compatible with the applicant's patented intelligent ice melter for railway high-voltage overhead contact lines. The eddy current de-icing module of the intelligent de-icing device can be replaced and installed according to actual needs. The cross-chord crossing of this utility model is different from the rotating clamp left A and rotating clamp right A of the intelligent de-icing device for railway high-voltage contact network in the applicant's patent. The cross-chord crossing of this utility model can provide a sufficiently large compressive force to make the heat source coil fit tightly together, while the rotating clamp left A and rotating clamp right A cannot provide a sufficiently large force because their closure is only achieved by limited elasticity. The anchor section crossing of this utility model is different from the switching guide of the intelligent de-icing device for railway high-voltage contact network in the applicant's patent. The anchor section crossing determines the direction of movement of the equipment by controlling whether the guide works or not, so that the equipment can enter the non-working support of the contact line to wait for the train to run, while the switching guide cannot change the working state.

[0008] The structure at the joint of the high-speed rail contact anchor section has the following characteristics: the contact wire of a single electrical phase is composed of multiple independent contact wire segments connected by the anchor section structure. When each contact wire segment is initially connected, it extends continuously from high to low and from left to right by a cantilever support (assuming the cantilever support is on the left side of the track) until it passes through the initial contact zone (the initial contact zone is the intersection and switching point between the non-working and working branches of the contact wire, i.e., a contact wire has both working and non-working branches). The initial contact zone is the working height of the contact wire and also the lowest point of the non-working branch of the contact wire. The bottom point; at the same time, when each segment of the contact wire is finally connected, it extends from the initial contact area from low to high and from right to left to the cantilever support; that is, the working support of the contact wire is always on the rightmost and bottommost side. The present invention only needs to ensure that the equipment can always move along the right side to pass through the contact wire anchor joint; the anchor section crossing utilizes the characteristics of the contact wire anchor joint. The designed guide and the switching auxiliary frame ensure that the equipment will inevitably move to the right in the initial contact area, and the designed switching auxiliary frame ensures that the left side of the equipment can smoothly pass through the non-working support of the contact wire without damaging the equipment.

[0009] Specifically, the high-voltage line miniature de-icing device includes a de-icing body, a cross-chord crossing, an anchor section crossing, a power supply and power supply module, an energy acquisition module, and a de-icing drive module. The energy acquisition module obtains electrical energy from the contact wire of the railway contact network to power the de-icing body. The de-icing drive module and the power supply and power supply module propel the high-voltage line miniature de-icing device forward on the contact network. The cross-chord crossing is used to pass through the contact network droppers and positioners. The anchor section crossing allows the high-voltage line miniature de-icing device to smoothly pass through the contact network anchor section joint. The high-voltage line miniature de-icing device can continuously and repeatedly de-ic within a single electrical phase. Simultaneously, the anchor section crossing can move in advance to the non-working support of the contact network when a high-speed train or electric locomotive passes, preventing the de-icing equipment from affecting the normal operation of the train.

[0010] The de-icing core is installed within the core mounting slot of the silica ceramic insulation. It is cylindrical in shape with a conical hollow center to facilitate close contact with the ice layer on the contact wire during the de-icing process, enabling rapid de-icing through heat exchange. The de-icing core is made of ferrous material with high magnetic and electrical permeability and consists of two parts that merge into one during operation. The de-icing core is enclosed and surrounded by the silica ceramic insulation, specifically by the heat source coil within it. When the heat source coil is connected to a high-voltage, high-frequency alternating current, the de-icing core generates a large amount of eddy current heat through electromagnetic induction, which melts the ice in contact with it. The ice layer contains a melting iron core situated within the magnetic field generated by the contact wire. While both magnetic field vectors exist, the magnitude difference between them is significant, resulting in minimal impact on the eddy current heat generated by the electromagnetic induction of the melting iron core. Furthermore, the melting iron core has a small constriction radius. Although it is electrically connected to the contact wire, the higher resistance of the iron core compared to the copper contact wire leads to a smaller current flowing through it, and the current is perpendicular to the direction of the eddy currents within the melting iron core, thus minimizing its influence on eddy current generation. The silicon oxide ceramic insulation consists of two cylindrical parts with a mounting groove for the iron core in the center. The silica ceramic insulation has coil mounting holes for mounting the heat source coil. The silica ceramic insulation also insulates the heat source coils from each other and from the de-icing core. Two coil outlet holes are located on the left half of the silica ceramic insulation in the forward direction, for connecting and disconnecting the beginning and end of the heat source coil, respectively. The silica ceramic insulation is a high-temperature resistant insulating material, resistant to cracking when heated and cooled. A groove can be formed inside the silica ceramic insulation to firmly embed the de-icing core. The core mounting groove, located in the middle of the silica ceramic insulation, is used to mount the de-icing core and consists of two parts. When combined, they form a cylindrical shape, and the iron core mounting slot can firmly embed the ice-melting iron core within it; the coil mounting hole is located inside the silica ceramic insulation and is used to insert the heat source coil. The coil mounting hole consists of two parts, which, when combined, form a spring-like hole for a complete heat source coil to pass through, with the inlet and outlet being two coil outlet holes respectively; one end of the ceramic connector is fixedly connected to two silica ceramic insulators, and the other end is fixedly connected to one end of the push rod on the inner side of the "L"-shaped corner, which can drive the ice-melting body on the left side of the forward direction to reciprocate through the silica ceramic insulation;The heat source coil consists of two parts, left and right, which are respectively embedded in the left and right parts of the silicon oxide ceramic insulation. During operation, they merge into one unit, and the entire heat source coil is switched on. The heat source coil is made of copper, a material with good conductivity. When merged, it forms a spiral spring structure that perfectly matches the coil mounting hole and the coil outlet hole. The heat source coil is composed of several inclined arc segments, which can be spliced ​​together through the coil mounting hole to form a complete spring structure, firmly locked in the coil mounting hole, and cannot wobble, so as to ensure tight contact under the strong compression of the cross-string passage. The coil outlet hole is located in... On the silicon oxide ceramic insulation, the two ends of the heat source coil are connected and disconnected. The coil outlet hole is fitted with the two ends of the heat source coil and connected to the frequency booster inverter via an insulated spring wire. The frequency booster inverter is used to convert the low-voltage DC power obtained by the power acquisition module into high-voltage, high-frequency AC power, and then connect it to the heat source coil via a wire. The frequency booster inverter is also used to convert the low-voltage DC power provided by the power supply and power supply module into high-voltage, high-frequency AC power, and then connect it to the heat source coil via a wire, ultimately heating the de-icing iron core through electromagnetic induction.

The lead screw then rotates to complete the telescopic, lifting, and horizontal pushing movements of the equipment. The left lifting device includes the motor and gear set, the lifting tube, the lifting rod, and the lead screw, used to drive the horizontal pushing support plate to move up and down through the lifting of the lifting rod.

One end of the rising pipe is fixedly connected to the housing of the motor and gear set, and it is hollow inside to provide extension and retraction for the lifting rod. The support frame is used to connect the melting ice body through the housing of the motor and gear set on the cross-chord. The support frame is used to... The anchor section crossing, the power supply and power generation module, the power acquisition module, and the de-icing drive module are connected and installed. At most, only one of the two anchor section crossings and one power acquisition module on the support frame can be in an open switching state. One end of the lifting rod is fixedly connected to the flat support plate. The lifting rod is installed inside the lifting tube, and its inner surface is threaded to mesh with the screw on the outer surface of the lead screw, pushing the lifting rod to move up and down during the rotation of the lead screw. One end of the lead screw is fixedly installed at the output end of the gear set of the motor and gear group, and can drive the lead screw to rotate when the motor and gear group are working. The outer surface of the lead screw is provided with a screw that can engage with the inner surface of the lifting rod. The threaded engagement allows the lifting rod to move up and down when the lead screw rotates, similar to how a rotating screw pushes a non-rotating nut to move back and forth. The front of the pushing device includes the gear set and motor, the pushing tube, the pushing rod, and the lead screw, used to push the ceramic connector, the de-icing core, the silicon oxide ceramic insulation, and the heat source coil on the left side to reciprocate to the left in the forward direction via the pushing rod. The rear of the pushing device includes the gear set and motor, the pushing tube, the pushing rod, and the lead screw, used to push the ceramic connector, the de-icing core, the silicon oxide ceramic insulation, and the heat source coil on the right side to reciprocate to the right in the forward direction via the pushing rod.The gear set and motor housing are fixedly installed on the left and right sides of the flat push support plate, and are staggered front to back. One end of the gear set and motor housing is fixedly connected to the flat push tube. The gear set of the gear set and motor is fixedly connected to the lead screw, and can drive the lead screw to perform telescopic movement. One end of the flat push tube is installed and fixed to one end of the gear set and motor housing. The flat push tube is hollow inside to provide support for the telescopic movement of the flat push rod. The diameter of the flat push tube is smaller than the length and width of the gear set and motor housing. The inner surface of the flat push rod is threaded, which can match and mesh with the screw on the outer surface of the lead screw, and can push the flat push rod to move back and forth when the lead screw rotates. One end of the flat push rod is connected to the ceramic The connecting body is fixedly connected; the outer surface of the lead screw is provided with a screw that can match and engage with the thread on the inner surface of the push tube. The bottom end of the lead screw is fixedly connected to the gear set and the motor, and can rotate under the drive of the gear set and the motor, thereby pushing the push rod to perform telescopic movement, and finally driving the ceramic connecting body and the silicon oxide ceramic insulation, the ice melting iron core and the heat source coil fixedly connected to the ceramic connecting body to move left and right together; the push support plate is used to install and fix the front and rear of the push device, that is, to install and fix the gear set and motor housing on the front and rear of the push device. The bottom of the push support plate is fixedly connected to the top of the lifting rod, and can be pushed by the lifting rod. The device performs lifting and lowering movements. The infrared mounting plate is fixedly installed on the brackets of the rotating mechanism open (A) and the rotating mechanism closed (A), and is used to install the infrared ranging module. The infrared ranging module is installed at one end of the infrared mounting plate and is used to detect the presence or absence of the contact wire cantilever bracket. That is, when the infrared ranging module detects the contact wire cantilever bracket, the melting ice material is about to pass or has already passed the locator under the contact wire cantilever bracket. At this time, the infrared ranging module transmits information feedback to the switching control module within the rotating mechanism open (A) or the rotating mechanism closed (A). The switching control module controls the left and right extension and retraction movements of the lifting device to complete the action of the melting ice material passing through the contact wire cantilever locator. The distance module calculates the distance between the device and the infrared ranging module through the principle of infrared reflection, which has advantages such as the ability to measure curved surfaces and good adaptability. At the same time, the contact rod extension opening A and contact rod extension closing A on the rotating mechanism opening A and the rotating mechanism closing A can also touch the positioner, and the two can serve as double confirmation evidence before the device passes through the positioner. The rotating mechanism opening A is fixedly installed on the support frame. The rotating mechanism opening A is the structure claimed in the applicant's patent high-voltage line micro ice melter.X. The rotating mechanism opening A is equipped with the switching control module to control the lifting and pushing operations of the left, right, front, and rear of the lifting device.The rotating mechanism switch A is fixedly installed on the support frame. The rotating mechanism switch A is the structure claimed in claim X of the applicant's patent for a high-voltage line miniature ice melter. The rotating mechanism switch A is equipped with the switching control module used to control the lifting and pushing operations of the left, right, front, and rear lifting devices. The contact wire is a standard structure for railway contact networks. The dropper is a standard structure for railway contact networks.

[0012] The guide is fixedly mounted on the guide post and is made of wear-resistant flexible material. It is an open, arc-shaped device with a semi-circular groove in the center. The radius of the groove is larger than the radius of the contact line, allowing it to be squeezed by the contact line and thus guiding the high-voltage line miniature ice melter to move to the right in the forward direction. The height of the guide is approximately equal to the height of the contact line. A certain gap is left between the guide and the contact line outside the anchor joint to prevent long-term friction between the contact line and the guide. One end of the guide post is used to mount the guide, and the other end is fixedly connected to the telescopic rod to support the guide. The telescopic device includes the telescopic tube, the telescopic rod, the lead screw, and the motor and gear set A. The device is used to drive the guide and the guide post to telescopically move via the telescopic rod. Specifically, when the high-voltage line miniature de-icing device needs to move through the contact wire anchor joint to the non-working support of the contact wire to wait for a train to pass, the telescopic device retracts in advance to lower the height of the guide and the guide post, causing the guide to detach from the contact wire and thus preventing the high-voltage line miniature de-icing device from completing its guiding work. Ultimately, the high-voltage line miniature de-icing device moves along the contact wire at the lower part of the contact wire anchor joint to the contact wire cantilever arm leading out of the non-working support. One end of the telescopic tube is fixedly installed on the housing of the motor and gear set A, and is hollow inside, used to install the telescopic rod and the lead screw, and allows the telescopic rod to move back and forth within the telescopic tube. The inner surface of the rod is threaded, which can mesh with the screw on the outer surface of the lead screw, and can push the telescopic rod to move back and forth under the rotation of the lead screw. Its working principle is similar to that of a rotating screw pushing a non-rotating nut to move back and forth. The top end of the telescopic rod is fixedly connected to the guide post, which is used to push the guide and the guide post to move back and forth when the motor and gear set A drive the lead screw to rotate. One end of the lead screw is fixedly connected to the output end of the gear set of the motor and gear set A, and can rotate under the drive of the motor and gear set A. The outer surface of the lead screw is provided with a screw, which can mesh with the thread on the inner surface of the telescopic rod, and can rotate. The housing of the motor and gear set A is fixedly mounted on the support. At the front end of the main frame, the output end of the gear set of the motor and gear set A is fixedly connected to one end of the lead screw, and can drive the lead screw to rotate together. The top of the housing of the motor and gear set A is fixedly connected to the telescopic tube. The motor and gear set A are controlled by the switching control module through the control line to move. The switching auxiliary frame is made of wear-resistant and insulating flexible material. The switching auxiliary frame is installed and fixed on the top of the silicon oxide ceramic insulated front end on the left side of the forward direction. It consists of two parts: a horizontal sliding plate and an arc-shaped block. The arc-shaped block is used to prevent the high-voltage line miniature de-icing device from scraping or getting stuck in the contact wire at the joint of the contact wire anchor section. The horizontal sliding plate is used to assist the non-working support of the contact wire to finally slide into the guide and the de-icing iron core.

[0013] The power supply housing is installed and fixed on the left side of the support frame in the forward direction. The power supply is used to store the electrical energy acquired by the power acquisition module, and at the same time provides the power required for the operation of the high-voltage line miniature ice melter's ice melting body, the cross-chord crossing, the anchor section crossing, the power acquisition module, and the de-icing drive module. The switching control module is used to control the actions of the cross-chord crossing and the anchor section crossing through the control line, thereby enabling the high-voltage line miniature ice melter to smoothly pass through the drop wire, the contact wire anchor section joint, the positioner on the contact wire cantilever arm, and switch to the non-working support of the contact wire to wait for the passing train. The connecting line is installed inside the support frame and is used to connect the power acquisition module, The power supply and power supply module are connected to the ice melting body, the cross-chord crossing, the anchor section crossing, and the de-icing drive module, and provide electrical energy for the operation of the ice melting body, the cross-chord crossing, the anchor section crossing, and the de-icing drive module; the control line is used to connect the switching control module and the left and right lifting devices, the front and rear of the horizontal pushing device, the rotating mechanism open A, the rotating machine closed A, and the infrared ranging module, that is, to receive the information transmitted by the rotating mechanism open A, the rotating machine closed A, and the infrared ranging module, and after judging and processing this information, control the actions of the left and right lifting devices, the front and rear of the horizontal pushing device.

[0021] This utility model embodiment provides a high-voltage line miniature ice melter, such as... Figure 2As shown, the de-icing core 1-01 is installed in the core mounting groove 1-03 of the silicon oxide ceramic insulator 1-02. It is cylindrical in shape with a conical hollow center to facilitate close contact with the ice layer on the contact wire 2-17 during the de-icing process, thereby rapidly melting the ice through heat exchange.

It is made of wear-resistant flexible material and is an open arc shape with a semi-circular groove in the middle. The radius of the groove is larger than the radius of the contact line (2-17). It is used to be squeezed by the contact line (2-17) and thus guide the high-voltage line micro ice melter to move to the right in the forward direction. The height of the guide (3-01) is about the same as the height of the contact line (2-17). One end of the guide post (3-02) is used to install the guide (3-01), and the other end is fixedly connected to the telescopic rod (3-05) to support the guide (3-01). The telescopic device (3-03) includes the telescopic tube (3-04), the telescopic rod (3-05), the lead screw, and the motor and gear set A (3-06). The telescopic device (3-03) is used to drive the guide (3-01) and the guide column (3-02) to telescopically move through the telescopic rod (3-05). That is, when the high-voltage line miniature de-icing device needs to move through the contact wire anchor section joint to the non-working support of the contact wire to wait for the train to run, the telescopic device (3-03) retracts in advance to reduce the height of the guide (3-01) and the guide column (3-02), causing the guide (3-01) to detach from the contact wire (2-17) and thus unable to complete the guiding work of the high-voltage line miniature de-icing device. Finally, the high-voltage line miniature de-icing device moves on the contact wire at the lower part of the contact wire anchor section joint to the contact wire arm leading out of the non-working support. One end of the telescopic tube (3-04) is fixedly installed on the outer shell of the motor and gear set A (3-06).

The switching auxiliary frame (3-07) is installed and fixed on the top of the front end of the silicon oxide ceramic insulator (1-02) on the left side of the forward direction. It consists of two parts: a horizontal sliding plate and an arc-shaped blocking plate. The arc-shaped blocking plate is used to prevent the high-voltage line miniature de-icing device from scraping or getting stuck in the contact wire (2-17) at the joint of the contact wire anchor section. The horizontal sliding plate is used to assist the non-working support of the contact wire (2-17) to finally slide into the guide (3-01) and the de-icing iron core (1-01).
