Abstract
Description
Technical Field
[0001] This utility model relates to the field of power transmission line monitoring technology, and in particular to a device for monitoring conductor galloping in power transmission lines. Background Technology
[0002] The twisting motion of conductors is the main cause of galloping. When conductors gallop with large amplitude, they will form a torsional motion of the same period. Galloping of transmission line conductors has long been an important factor affecting the safety of transmission lines in the region during winter. It can cause transmission line tripping, bolts falling off the crossarms of the towers, and damage to the crossarms, jumpers, insulators, and hardware of the towers, making the operation of the power grid extremely difficult.
[0003] The conductor galloping monitoring system uses data acquisition sensors installed on the conductors to collect data and send it to a monitoring host to prevent the hazards caused by conductor galloping.
[0004] Existing conductor galloping monitoring devices include a data acquisition unit and a monitoring host. The data acquisition unit is installed on the line to collect data and transmit it to the monitoring host. The existing data acquisition unit consists of an acquisition section and an installation section. The installation section mainly uses bolts to connect to the acquisition section, with clamping ends between the two clamping the line, as shown in the attached diagram. Figure 5 As shown, since the lower part of the installation section is enclosed, the installation section needs to be separated from the acquisition section when installing the data acquisition unit, and the cable can only be installed after being placed between the two. This is inconvenient during installation. Therefore, we propose a vibration monitoring device that can easily insert the cable into the data acquisition unit for convenient installation of the data acquisition unit. Utility Model Content
[0005] To achieve the above objectives, this utility model proposes a transmission line conductor galloping monitoring device, including a data acquisition unit. The data acquisition unit includes a monitoring end and an installation end. The installation end includes a mounting column fixedly installed on the lower surface of the monitoring end. A sliding seat is slidably installed on the surface of the mounting column. An opening is provided on the side of the sliding seat. A positioning plate is slidably connected to the inner wall of the opening. An inclined groove is provided on the lower surface of the positioning plate. A moving block is fixedly connected to the upper surface of the positioning plate. A moving groove for the moving block to slide is provided on the inner top wall of the opening. A return spring is fixedly connected to the opposite surface of the moving block and the moving groove.
[0006] The lower surface of the monitoring end is rotatably connected to a screw that drives the sliding seat to move, and the upper surface of the positioning plate has a movable opening, with the screw located inside the movable opening.
[0007] In one example, the upper surface of the sliding seat has a sliding hole, the surface of the mounting post overlaps with the inner wall of the sliding hole, and the mounting post is T-shaped.
[0008] In one example, the lower surface of the monitoring end is provided with an arc-shaped groove, and a rubber pad is fixedly connected to the inner wall of the arc-shaped groove.
[0009] In one example, the inclination of the inclined groove is not less than 45°.
[0010] In one example, the upper surface of the movable block is provided with a T-shaped groove, and a T-shaped insert is slidably connected to the inner wall of the T-shaped groove.
[0011] In one example, a connecting spring is fixedly connected to the opposite face of the T-shaped plug and the T-shaped slot, and both sides of the T-shaped plug are arc-shaped.
[0012] In one example, the inner top wall of the movable slot has a positioning slot adapted to the T-shaped insert.
[0013] In one example, the upper surface of the sliding seat has a threaded hole, and the surface of the screw is threadedly connected to the inner wall of the threaded hole.
[0014] The transmission line conductor galloping monitoring device proposed in this utility model can bring the following beneficial effects:
[0015] 1. This utility model, by setting a positioning plate and utilizing the inclined groove below the positioning plate, can realize the automatic opening of the positioning plate. Furthermore, by setting a moving block and a reset spring, the positioning plate can be returned to its original position after opening, which facilitates the connection of the data acquisition unit to the circuit. Compared with the existing manual installation of the positioning component below, this is more convenient.

[0026] To more clearly illustrate the overall concept of this utility model, a detailed description will be provided below with reference to the accompanying drawings.
[0027] In the description of this utility model, it should be understood that the terms "center", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "axial", "radial", "circumferential", etc., indicating the orientation or positional relationship are based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.
[0028] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.
[0029] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection, an electrical connection, or a communication connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components.

In this specification, the illustrative expressions of the above terms do not necessarily refer to the same solution or example. Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more solutions or examples.
[0031] like Figures 1 to 4 As shown, this utility model proposes a transmission line conductor galloping monitoring device, including a data acquisition unit 1. The data acquisition unit 1 includes a monitoring end 101 and an installation end 102. The main internal structure of the monitoring end 101 includes sensors, an analog-to-digital converter (ADC), and a digital signal processing chip. The sensors are responsible for collecting acceleration data and meteorological parameters such as temperature, humidity, wind speed, and wind direction during conductor galloping. The ADC converts the analog signals collected by the sensors into digital signals, performs preliminary processing, and stores the data. The sensors include a triaxial accelerometer and a micro-meteorological sensor. The triaxial accelerometer collects acceleration data during conductor galloping and can simultaneously measure acceleration in both horizontal and vertical directions. The micro-meteorological sensor monitors meteorological parameters such as ambient temperature, humidity, wind speed, and wind direction of the transmission line in real time, providing important information for galloping prediction. A solar photovoltaic panel is installed on the top of the monitoring end 101 to provide power. The data acquisition unit 1 is connected to the monitoring host, transmitting the collected information to the monitoring host. The monitoring host ultimately aggregates the data to the monitoring center, achieving real-time remote online monitoring.
[0032] The mounting end 102 includes a mounting post 2 fixedly mounted on the lower surface of the monitoring end 101. A sliding seat 3 is slidably mounted on the surface of the mounting post 2. There are four mounting posts 2 arranged in a rectangular array on the lower surface of the monitoring end 101. A sliding hole is opened on the upper surface of the sliding seat 3. The surface of the mounting post 2 overlaps with the inner wall of the sliding hole. In order to prevent the sliding seat 3 from falling off the mounting post 2, the mounting post 2 is designed as a T-shape, and the protruding bottom can support the sliding seat 3.
[0033] There are two sliding seats 3, and each of the two sliding seats 3 has an opening on its opposite side. A positioning plate 4 is slidably installed inside the opening. The positioning plate 4 is located below the monitoring end 101. The sliding seat 3 moves upward, causing the positioning plate 4 to move upward, which in turn can clamp and fix the line with the monitoring end 101. In order to ensure that the data acquisition unit 1 clamps the line stably, an arc-shaped groove is provided at the bottom of the monitoring end 101. A rubber pad is fixedly connected to the inner wall of the arc-shaped groove. The deformation of the rubber pad can ensure that the rubber pad wraps the line and ensures the stability of the data acquisition unit 1.
[0034] To facilitate the installation of the data acquisition unit 1 on the line, a sloping groove 5 is provided on the lower surface of the positioning plate 4. The inclination of the sloping groove 5 is not less than 45°. During installation, the sloping groove 5 of the positioning plate 4 is aligned with the line and pressed down. At this time, the sloping groove 5 of the positioning plate 4 overlaps with the surface of the line. In the force analysis, the positioning plate 4 will be subjected to a force that moves to both sides under the sloping force of the sloping groove 5. Therefore, the positioning plate 4 can automatically open to both sides to ensure that the line is located between the monitoring end 101 and the positioning plate 4.
[0035] To ensure the positioning plate 4 returns to its original position after moving to both sides, a movable block 6 is fixedly connected to the upper surface of the positioning plate 4. A movable groove is opened in the inner top wall of the opening, and the movable block 6 is located inside the movable groove. A return spring 7 is fixedly connected to the opposite side of the movable block 6 and the movable groove. When the positioning plate 4 opens and moves, the movable block 6 moves with the positioning plate 4, and the movable block 6 will squeeze the return spring 7. After the line passes through the positioning plate 4, the force on the positioning plate 4 stops. At this time, the elastic force of the return spring 7 will push the movable block 6 to move. The movable block 6 drives the positioning plate 4 to return to its original position in the opposite direction. The opposite sides of the two positioning plates 4 overlap, which can ensure the filling under the line and ensure that the positioning plate 4 can clamp the line.
[0036] A T-shaped groove is formed on the upper surface of the movable block 6. A T-shaped insert 8 is slidably connected to the inner wall of the T-shaped groove. Both sides of the T-shaped insert 8 are arc-shaped. A connecting spring 9 is fixedly connected to the opposite side of the T-shaped insert 8 and the T-shaped groove. A positioning groove 10 adapted to the T-shaped insert 8 is formed on the inner top wall of the movable groove away from the T-shaped insert 8. The length of the movable groove is greater than the length of the positioning plate 4 extending out of the sliding seat 3. During normal installation, the positioning plate 4 moves into the sliding seat 3. At this time, the movable block 6 moves, but the T-shaped insert 8 does not move a certain distance. Upon reaching the positioning slot 10, when disassembling the data acquisition unit 1, manually pull the positioning plate 4. At this time, pull the positioning plate 4 with full force so that the T-shaped insert 8 moves into the positioning slot 10. Under the elastic force of the connecting spring 9, the T-shaped insert 8 is inserted into the positioning slot 10, which can position the positioning plate 4 and prevent the positioning plate 4 from moving, making the bottom opening of the data acquisition unit 1 easy to remove. When actively pushing the positioning plate 4, the arc surface of the T-shaped insert 8 will be forcefully retracted into the T-shaped slot, and the T-shaped insert 8 will disengage from the positioning slot 10, so that the positioning plate 4 returns to its position.
[0037] A threaded hole is provided in the middle of the lower surface of the positioning plate 4, and a screw 11 is threadedly connected to the inner wall of the threaded hole. The end face of the screw 11 is rotatably connected to the lower surface of the monitoring end 101 through a bearing. When the screw 11 is rotated, the sliding seat 3 cannot rotate due to the restriction of the two mounting posts 2, and can only move. Therefore, the screw 11 can drive the sliding seat 3 to move up and down, thereby cooperating with the monitoring end 101 to clamp the line. Since the screw 11 passes through the sliding seat 3, in order to avoid the screw 11 interfering with the movement of the positioning plate 4, a movable opening is provided on the upper surface of the positioning plate 4. The screw 11 is located inside the movable opening. When the positioning plate 4 moves, the screw 11 is located inside the movable opening and will not block the positioning plate 4.

Each embodiment focuses on describing the differences from other embodiments. In particular, the system embodiments are basically similar to the method embodiments, so the description is relatively simple; relevant parts can be referred to the descriptions in the method embodiments.
[0039] The above description is merely an embodiment of this utility model and is not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principle of this utility model should be included within the scope of the claims of this utility model.
