Description

Technical Field

[0001] This invention relates to the field of line maintenance technology, and in particular to a vibration de-icing device and method for monitoring icing on overhead transmission lines. Background Technology

[0002] Icing on overhead transmission lines refers to the phenomenon where raindrops, fog droplets, or supercooled water droplets freeze on the surface of conductors, ground wires, and other line components under low temperature, high humidity, and specific meteorological conditions, forming an ice layer. Icing significantly increases the mechanical load on the line, leading to increased conductor sag, tower stress imbalance, and in severe cases, line breaks, tower collapses, galloping, or even large-scale power outages. Types of icing mainly include rime, hoarfrost, mixed rime, and wet snow, and their formation is closely related to temperature, wind speed, humidity, and precipitation patterns. Therefore, icing is one of the major natural disasters threatening the safe and stable operation of the power grid and needs to be prevented and controlled through monitoring and early warning, anti-icing design, and de-icing technology.

[0003] Existing vibratory de-icing devices are typically installed and operated only on a single transmission line, meaning each device can only operate on one conductor or ground wire, and cannot cover multiple lines simultaneously. This "one-to-one" deployment method has significant limitations in practical applications: on the one hand, in high-voltage or ultra-high-voltage transmission systems with multiple circuits and multiple split conductors, achieving comprehensive de-icing requires installing independent vibratory devices on each conductor, resulting in a significant increase in the number of devices; on the other hand, the large number of dispersed devices not only increases the initial investment cost but also adds complexity and expense to subsequent operation, maintenance, and energy supply. Summary of the Invention

[0004] The purpose of this invention is to provide a vibration de-icing device and method for monitoring icing on overhead transmission lines, which can be installed on line clamps to de-ic multiple lines on the clamps to improve work efficiency.

[0005] To achieve the above objectives, in a first aspect, the present invention provides a vibration de-icing device for monitoring icing on overhead transmission lines, comprising a support assembly, a moving assembly, and a vibration assembly. The support assembly includes a support plate, two sliding clamps, and a clamping device. The two sliding clamps are slidably disposed on both sides of the support plate, and the clamping device is used to fix the two sliding clamps. The moving component includes a rotator, a sliding rod, and a control cylinder. The rotator is rotatably mounted on the support plate, the control cylinder is mounted on the rotator, and the sliding rod is connected to the output end of the control cylinder. The vibration assembly includes a mounting shell, two clamping blocks, a control screw, and a vibrator. The mounting shell is fixed to the sliding rod and has a wire inlet groove. The two clamping blocks are slidably disposed in the wire inlet groove. The control screw has two opposite threads and is threadedly connected to the two clamping blocks. The vibrator is disposed inside the mounting shell. When the control screw moves the two clamping blocks closer together, it pushes the power transmission line located between the two clamping blocks to contact the vibrator.

[0006] The sliding clamp includes a clamp body, two rotating plates, a push block, and a spring. The clamp body is slidably disposed on one side of the support plate, the push block is slidably disposed on the clamp body, the two rotating plates are rotatably disposed on both sides of the push block, and the spring is disposed between the push block and the clamp body. When the clamp body approaches the wire clamp, the wire clamp pushes the push block to slide, thereby causing the two rotating plates to rotate and press the wire clamp.

[0007] The clamping device includes two pull rods, a push block, a push screw, and a push motor. The push block is slidably disposed on one side of the support plate. One end of each of the two pull rods is rotatably connected to the two clamping bodies, and the other end of each pull rod is rotatably connected to the push block. The push screw is threadedly connected to the push block, and the output end of the push motor is connected to the push screw.

[0008] The rotating device includes a rotating disk, a gear, a gear ring, and a second motor. The rotating disk is rotatably mounted on the support disk, the gear ring is fixed on the rotating disk, the gear is rotatably mounted on the support disk and meshes with the gear ring, and the output end of the second motor is connected to the gear.

[0009] The mounting housing has a guide block, which is disposed on one side of the inlet slot.

[0010] The overhead transmission line icing monitoring and vibration de-icing device also includes a solar panel, which is located on one side of the support plate.

[0011] The overhead transmission line icing monitoring and vibration de-icing device further includes a monitoring component, which includes a mover, a photoelectric detection unit, a data processing unit, and a control unit. The mover is slidably disposed within the mounting housing, the photoelectric detection unit is disposed within the mover, the data processing unit is connected to the photoelectric detection unit, and the control unit is connected to the data processing unit and the vibrator.

[0012] The mover includes a moving screw, a detection block, a bonding block, an inclined guide rail, and a second spring. The detection block is slidably disposed within the mounting housing. The moving screw is threadedly connected to the detection block. The bonding block is slidably disposed on the detection block. The inclined guide rail is fixed within the housing. When the moving screw is rotated to move the detection block, the bonding block moves closer to the conductor along the inclined guide rail and drives the photoelectric detection unit to detect the ice thickness on the conductor. The second spring is used to move the bonding block closer to the detection block when the bonding block is reset.

[0013] The monitoring component further includes a data uploading unit, which is connected to the data processing unit and is used to upload monitoring data.

[0014] Secondly, the present invention also provides a vibration de-icing method for monitoring icing on overhead transmission lines, using the aforementioned vibration de-icing device for monitoring icing on overhead transmission lines.

[0015] This invention discloses a vibration de-icing device and method for monitoring icing on overhead transmission lines. The support plate has a ring-shaped or arc-shaped structure for easy installation around the transmission conductor. Two sliding clamps are symmetrically arranged on both sides of the support plate and can slide radially along the support plate to accommodate transmission conductors of different diameters. A clamping device is provided on the support plate to lock and fix the sliding clamps after they are adjusted to the correct position, thereby ensuring that the entire device is firmly installed on the clamps and preventing loosening or displacement during operation.

[0016] The rotator is rotatably mounted on the support plate via a bearing structure, allowing it to rotate freely around the transmission axis. A control cylinder is fixedly mounted on the rotator, with one end of a sliding rod connected to the output end of the control cylinder, enabling telescopic movement under the cylinder's drive. By controlling the cylinder's telescopic movement, a vibration assembly mounted on the sliding rod can be moved closer to any transmission line requiring de-icing.

[0017] The mounting housing of the vibration assembly is fixedly connected to the end of the sliding rod. A through-hole inlet groove is provided on the side facing the power transmission line to accommodate and guide the power transmission line. Two clamping blocks are symmetrically slidably disposed inside the inlet groove, with anti-slip textures or elastic pads on their inner surfaces to enhance clamping stability. A control screw extends laterally through the two clamping blocks and has two sections of oppositely helical threads (i.e., left-hand and right-hand threads). When the control screw is driven to rotate by a motor or manual knob, the two clamping blocks will move synchronously towards or away from each other. When the clamping blocks move towards each other and contact the power transmission line, they can stably clamp it. At this time, the vibrator integrated inside the mounting housing is activated, generating high-frequency mechanical vibration, which is transmitted to the surface of the power transmission line through the clamping blocks. This causes the ice layer attached to it to crack and fall off due to alternating stress, thus achieving efficient de-icing.

[0018] This invention features a compact structure and strong adaptability. It can be installed on line clamps to de-ice multiple lines on the clamp, thereby improving work efficiency. It is suitable for winter anti-icing and disaster relief operations on various high-voltage and ultra-high-voltage overhead transmission lines, and has significant practical value and promising prospects for widespread application.

[0030] Please see Figures 1-7This invention provides a vibration de-icing device for monitoring icing on overhead transmission lines, comprising a support assembly, a moving assembly, and a vibration assembly. The support assembly includes a support plate 101, two sliding clamps 102, and a clamping device 103. The two sliding clamps 102 are slidably disposed on both sides of the support plate 101, and the clamping device 103 is used to fix the two sliding clamps 102. The moving assembly includes a rotator 104, a sliding rod 105, and a control cylinder 106. The rotator 104 is rotatably disposed on the support plate 101, and the control cylinder 106 is disposed on the rotator 104. The sliding rod 105 is connected to the output end of the control cylinder 106. The vibration assembly includes a mounting housing 107, two clamping blocks 108, a control screw 109, and a vibrator 110. The mounting housing 107 is fixed to the sliding rod 105. A wire inlet groove 111 is provided on the mounting housing 107. The two clamping blocks 108 are slidably disposed in the wire inlet groove 111. The control screw 109 has two opposite threads and is threadedly connected to the two clamping blocks 108. The vibrator 110 is disposed in the mounting housing 107. When the control screw 109 drives the two clamping blocks 108 to approach each other, it pushes the power transmission line located between the two clamping blocks 108 to contact the vibrator 110.

[0031] In this embodiment, the support plate 101 has a ring-shaped or arc-shaped structure, which facilitates installation around the transmission line. Two sliding clamps 102 are symmetrically arranged on both sides of the support plate 101 and can slide along the radial direction of the support plate 101 to accommodate transmission lines of different diameters. A clamp 103 is provided on the support plate 101 to lock and fix the sliding clamps 102 after they are adjusted into place, thereby ensuring that the entire device is firmly installed on the line clamp 136 and preventing loosening or displacement during operation.

[0032] The rotator 104 is rotatably mounted on the support plate 101 via a bearing structure, allowing it to rotate freely. A control cylinder 106 is fixedly mounted on the rotator 104. One end of a sliding rod 105 is connected to the output end of the control cylinder 106, enabling it to extend and retract under cylinder drive. By controlling the extension and retraction of the control cylinder 106, the vibration assembly mounted on the sliding rod 105 can be moved closer to any power line requiring de-icing.

[0033] The mounting housing 107 of the vibration assembly is fixedly connected to the end of the sliding rod 105. A through-hole inlet groove 111 is provided on the side facing the power transmission line to accommodate and guide the power transmission line. Two clamping blocks 108 are symmetrically slidably disposed inside the inlet groove 111, with anti-slip textures or elastic pads on their inner surfaces to enhance clamping stability. A control screw 109 extends laterally through the two clamping blocks 108 and has two sections of oppositely helical threads (i.e., left-hand and right-hand threads). When the control screw 109 is driven to rotate by a motor or manual knob, the two clamping blocks 108 will move synchronously towards or away from each other. When the clamping blocks 108 move towards each other and contact the power transmission line, they can stably clamp it. At this time, the vibrator 110 integrated inside the mounting housing 107 is activated, generating high-frequency mechanical vibration, which is transmitted to the surface of the power transmission line through the clamping blocks 108. This causes the ice layer attached to it to crack and fall off due to alternating stress, thereby achieving efficient de-icing.

[0034] This invention has a compact structure and strong adaptability, and is suitable for winter anti-icing and disaster relief operations of various high-voltage and ultra-high-voltage overhead transmission lines. It has significant practical value and prospects for promotion.

[0035] The sliding clamp 102 includes a clamp body 112, two rotating plates 113, a push block 114, and a spring 115. The clamp body 112 is slidably disposed on one side of the support plate 101, the push block 114 is slidably disposed on the clamp body 112, the two rotating plates 113 are rotatably disposed on both sides of the push block 114, and the spring 115 is disposed between the push block 114 and the clamp body 112. When the clamp body 112 approaches the wire clamp 136, the wire clamp 136 pushes the push block 114 to slide, thereby driving the two rotating plates 113 to rotate and press the wire clamp 136.

[0036] The clamp body 112 has an overall arc or C-shaped structure, and its back is provided with a guide groove or slide rail, which allows it to slide smoothly along the radial direction of the support plate 101, thereby adapting to wire clamps 136 or wire fittings of different diameters. The push block 114 is embedded inside the clamp body 112 and can slide along the axial direction of the clamp body 112; two rotating plates 113 are rotatably connected to the two sides of the push block 114 by a pin or hinge structure, and the free end of the rotating plate 113 extends toward the wire clamp 136. Its inner surface can be covered with flexible materials such as rubber or polyurethane to increase friction and avoid damaging the surface of the wire clamp 136.

[0037] As the clamp 112 approaches the wire clamp 136, the wire clamp 136 first contacts and pushes the push block 114 to slide inward into the clamp 112. The movement of the push block 114, through a linkage effect, causes the rotating plates 113 on both sides to retract inward around their hinge points, thereby pressing the front end of the rotating plate 113 tightly against the outer wall of the wire clamp 136, forming a multi-point contact adaptive clamping effect. During this process, the spring 115, located between the push block 114 and the clamp 112, plays a buffering and resetting role: on the one hand, it absorbs impact energy in the initial contact stage to prevent rigid collisions; on the other hand, when the device is disassembled or released, the elastic force of the spring 115 can push the push block 114 to reset, causing the rotating plate 113 to automatically open, facilitating the quick release of the wire clamp 136. This structure not only improves the reliability of clamping but also effectively adapts to minor differences in the shape of the wire clamp 136, ensuring stable installation of the device under complex working conditions.

[0038] The clamping device 103 includes two pull rods 116, a push block 117, a push screw 118, and a push motor 119. The push block 117 is slidably disposed on one side of the support plate 101. One end of each of the two pull rods 116 is rotatably connected to the two clamping bodies 112, and the other end of each pull rod 116 is rotatably connected to the push block 117. The push screw 118 is threadedly connected to the push block 117, and the output end of the push motor 119 is connected to the push screw 118.

[0039] The clamping device 103 applies a synchronous locking force to the two sliding clamps 102, ensuring the entire device is firmly fixed on the power transmission line and preventing loosening or detachment due to wind vibration or de-icing vibration. The pushing block 117 is slidably mounted on one side of the support plate 101, its sliding direction perpendicular to or at a certain angle to the movement direction of the sliding clamps 102, to achieve effective force transmission. Two pull rods 116 correspond to the left and right sliding clamps 102 respectively. One end of each pull rod 116 is rotatably connected to the rear of the corresponding clamp body 112 via a pin, and the other end is rotatably connected to the pushing block 117, forming a double-rocker linkage mechanism.

[0040] When the drive motor 119 starts, its output shaft drives the drive screw 118 to rotate. Since the drive screw 118 and the drive block 117 are threaded together, the rotational motion of the screw is converted into the linear motion of the drive block 117. When the drive block 117 slides forward (or backward), the two pull rods 116 simultaneously pull (or push) the clamps 112 on both sides towards the center of the support plate 101, thus firmly pressing the sliding clamp 102 onto the wire clamp 136. Conversely, when the drive motor 119 rotates in the opposite direction, the drive block 117 retracts, the pull rods 116 loosen, and the sliding clamp 102 is released outward under its own weight or the action of the auxiliary spring 115, facilitating the installation and disassembly of the device. This clamping structure has advantages such as smooth transmission, large locking force, and good synchronization, and achieves automated control through motor drive.

[0041] The rotator 104 includes a rotating disk 120, a gear 121, a gear ring 122, and a second motor 123. The rotating disk 120 is rotatably mounted on the support disk 101. The gear ring 122 is fixed on the rotating disk 120. The gear 121 is rotatably mounted on the support disk 101 and meshes with the gear ring 122. The output end of the second motor 123 is connected to the gear 121.

[0042] The rotating disk 120 is rotatably mounted in the central area of ​​the support disk 101 via bearings or bushings, and its axis is substantially coincident with the axis of the support disk 101, enabling the entire moving and vibrating assembly to rotate freely 360°.

[0043] The gear ring 122 is fixedly mounted on the outer edge of the rotating disk 120 and is typically made of high-strength engineering plastic or metal, offering good wear resistance and transmission accuracy. The gear 121 is rotatably mounted on the support disk 101 via a shaft and maintains a constant meshing with the gear ring 122. The second motor 123 is fixed to the support disk 101, and its output shaft is directly or via a coupling connected to the gear 121. When the second motor 123 starts and rotates in both directions, it drives the gear 121 to rotate, which in turn drives the rotating disk 120 to rotate as a whole through the gear 121-gear ring 122 meshing pair to select the wire requiring de-icing.

[0044] The mounting housing 107 has a guide block 124, which is disposed on one side of the inlet slot 111.

[0045] The guide block 124 is typically wedge-shaped, arc-shaped, or has a convex structure with bevels, and is made of wear-resistant, low-friction materials (such as polytetrafluoroethylene or nylon). Its main function is to guide and straighten the transmission line as the device moves along the conductor: on the one hand, the guide block 124 can smoothly guide the slightly deviated or swaying conductor into the inlet groove 111, avoiding hard collisions between the clamping block 108 and the conductor; on the other hand, in cases of thick ice or irregular conductor surfaces, the guide block 124 can contact the edge of the ice layer in advance, acting as an "ice-breaking guide," reducing resistance during subsequent clamping and vibration processes, and improving de-icing efficiency and equipment safety.

[0046] The overhead transmission line icing monitoring and vibration de-icing device also includes a solar panel 125, which is disposed on one side of the support plate 101.

[0047] The solar module 125 includes a photovoltaic panel, an energy storage battery, and a power management module. It is installed as a whole on one side of the support plate 101 (usually facing south or in a location with optimal sunlight conditions) and securely fixed using brackets or clips. The photovoltaic panel converts daytime sunlight into electrical energy, which is then regulated and rectified by the power management module and stored in the energy storage battery. This provides continuous power to drive the motor 119, the second motor 123, the vibrator 110, the control screw 109 drive unit, and various sensors (such as ice thickness sensors, temperature and humidity sensors, and inclinometers).

[0048] The overhead transmission line icing monitoring and vibration de-icing device also includes a monitoring component, which includes a mover 126, a photoelectric detection unit 127, a data processing unit 128, and a control unit 129. The mover 126 is slidably disposed within the mounting housing 107. The photoelectric detection unit 127 is disposed within the mover 126. The data processing unit 128 is connected to the photoelectric detection unit 127. The control unit 129 is connected to the data processing unit 128 and the vibrator 110.

[0049] The mover 126 is slidably mounted inside the mounting housing 107, serving as a support and adjustment platform for the photoelectric detection unit 127. The photoelectric detection unit 127 (such as a laser rangefinder, infrared imaging module, or structured light scanner) is built into the mover 126 and is used for non-contact measurement of the outer diameter of the conductor and the thickness of the ice layer on its surface. The data processing unit 128 is electrically connected to the photoelectric detection unit 127 and is responsible for filtering, calibrating, extracting features, and calculating the ice thickness of the collected raw signals. The control unit 129 is electrically connected to the data processing unit 128 and the vibrator 110 respectively, and determines whether to start the vibration de-icing program according to the degree of icing. It can also dynamically adjust parameters such as vibration frequency and duration to achieve precise de-icing as needed.

[0050] The mover 126 includes a moving screw 130, a detection block 131, a bonding block 132, an inclined guide rail 133, and a second spring 134. The detection block 131 is slidably disposed within the mounting housing 107. The moving screw 130 is threadedly connected to the detection block 131. The bonding block 132 is slidably disposed on the detection block 131. The inclined guide rail 133 is fixed within the housing. When the moving screw 130 is rotated to drive the detection block 131 to slide, the bonding block 132 moves closer to the wire along the inclined guide rail 133 and drives the photoelectric detection unit 127 to detect the ice thickness of the wire. The second spring 134 is used to move the bonding block 132 closer to the detection block 131 when the bonding block 132 is reset.

[0051] The detection block 131 is slidably disposed inside the mounting housing 107 via a slide groove or guide rail structure, and can move smoothly in the horizontal or radial direction; The movable screw 130 passes through the detection block 131 and forms a threaded engagement with it. One end of the screw is driven by a micro stepper motor or a manual knob. When rotating, the displacement stroke of the detection block 131 can be precisely controlled. The bonding block 132 is slidably mounted on the detection block 131, and a flexible contact surface or optical window is provided on the side facing the wire, and a photoelectric detection unit 127 is embedded inside. The inclined guide rail 133 is fixed to the inner wall of the mounting shell 107 and is arranged in an inclined track. Its inclination angle has been mechanically optimized. When the moving screw 130 drives the detection block 131 to slide in the direction of the wire, the bonding block 132 moves downward along the inclined guide rail 133 under the push of the detection block 131, thereby realizing the composite motion trajectory of "horizontal feed → vertical pressing", so that the photoelectric detection unit 127 automatically approaches and faces the surface of the wire. The second spring 134 is located between the bonding block 132 and the detection block 131. After the detection is completed or when abnormal resistance is encountered, it can provide a buffering effect. When the moving screw 130 retracts, it pulls the bonding block 132 back to its original position, so that it is tightly attached to the detection block 131, thus preventing shaking from interfering with subsequent operations.

[0052] This structure cleverly utilizes the principle of inclined plane transmission to transform the unidirectional screw drive into the adaptive pressing action of the contact block 132 on the wire, effectively solving the problem of blind spots caused by changes in wire diameter, uneven icing, or device installation deviations, and ensuring that the photoelectric detection unit 127 is always at the optimal measurement distance and angle.

[0053] The monitoring component also includes a data uploading unit 135, which is connected to the data processing unit 128 and is used to upload monitoring data.

[0054] The monitoring component is also equipped with a data upload unit 135, which is communicatively connected to the data processing unit 128. It supports uploading key data such as real-time icing thickness, ambient temperature and humidity, and device operating status to a remote monitoring center or power grid dispatch platform via wireless communication methods such as 4G / 5G, LoRa, NB-IoT, or dedicated power grid. Maintenance personnel can remotely monitor the icing risk level of the lines through a visual interface and, when necessary, remotely trigger de-icing commands to achieve intelligent management.

[0055] This invention, through highly integrated monitoring components, not only achieves high-precision, adaptive, and non-contact sensing of icing conditions, but also constructs a complete information link from data acquisition to edge computing and cloud collaboration. This upgrades the entire de-icing device from a "passive response" to a new generation of transmission line anti-icing equipment that combines "active prevention and intelligent intervention," greatly improving the power grid's safe operation and emergency response efficiency under extreme icy and snowy weather. Example

[0056] The present invention also provides a vibration de-icing method for monitoring icing on overhead transmission lines, which employs the aforementioned vibration de-icing device for monitoring icing on overhead transmission lines.

[0057] The de-icing device is mounted around the clamp 136 of the overhead power transmission line to be monitored via a support assembly. The drive motor 119 in the drive clamp 103 causes the two sliding clamps 102 to move synchronously toward the center under the linkage of the pull rod 116, until the rotating plate 113 adaptively presses the surface of the clamp 136 with the cooperation of the push block 114 and the spring 115, thus completing the stable fixation of the device.

[0058] The sliding cylinder is activated, causing the mounting housing 107 to approach the power transmission line to be tested. Then, the monitoring component control unit 129 drives the moving screw 130 in the mover 126 to rotate, causing the detection block 131 to advance along the inner slide rail of the mounting housing 107. Guided by the inclined guide rail 133, the contact block 132 synchronously shifts towards the conductor, bringing the built-in photoelectric detection unit 127 (such as a laser ranging module, such as a Keyence LK-G5000 or SICK OD5000 series) close to the conductor surface. The photoelectric detection unit 127 emits a beam and receives the reflected signal, acquiring the conductor's outer diameter data in real time. The data processing unit 128, combined with the ice-free reference diameter (preset or historical data), calculates the current ice thickness and determines whether the ice thickness exceeds the safety threshold.

[0059] The data processing unit 128 performs comprehensive analysis on the collected ice thickness, distribution uniformity, and environmental parameters (such as temperature and humidity, which can be provided by additional sensors). If the ice thickness reaches a preset warning value (e.g., ≥5mm), the control unit 129 immediately generates a de-icing command; at the same time, the data uploading unit 135 transmits the monitoring results back to the remote monitoring platform in real time via the wireless communication module, so that the dispatch center can conduct a global risk assessment and resource allocation.

[0060] Simultaneously, the control screw 109 rotates, driving the two clamping blocks 108 to move towards each other, clamping the iced wire 136 tightly against the contact surface of the vibrator 110; the vibrator 110 then starts, generating high-frequency (e.g., 50–200 Hz), controllable amplitude mechanical vibration, which is transmitted to the surface of the wire through the clamping blocks 108. Under alternating stress, the ice layer generates microcracks and rapidly expands, eventually detaching completely, achieving efficient and low-damage de-icing.

[0061] After one de-icing operation is completed, the monitoring component is restarted to re-test the icing in the same area. If the residual ice layer still exceeds the standard, step four is repeated for supplementary de-icing; if the standard is met, the control unit 129 controls each actuator to reset, and then rotates the rotator 104 to another transmission line to be tested to repeat the above process, continuously performing periodic inspections (e.g., every 30 minutes) until the snowy weather ends.

[0062] Throughout the operation, solar panels 125 continuously power the system: during the day when there is sufficient sunlight, the photovoltaic panels charge the energy storage battery; at night or on cloudy days, the battery provides power, ensuring that the device can operate continuously for more than 7–15 days in remote mountainous areas without external power access. The power management module dynamically adjusts the power consumption of each unit, prioritizing monitoring and critical de-icing functions.

[0063] The above description discloses only one preferred embodiment of the present invention, and should not be construed as limiting the scope of the present invention. Those skilled in the art will understand that all or part of the processes of the above embodiments can be implemented, and equivalent changes made in accordance with the claims of the present invention are still within the scope of the invention.
