Description

Technical Field

[0001] This utility model relates to the field of online monitoring technology for ice melting and observation by conductors (ground wires), specifically to an online monitoring device for ice melting and observation by conductors (ground wires). Background Technology

[0002] Since the large-scale ice storm in 2008, online monitoring technology and devices for equivalent ice thickness of high-voltage distribution lines have been widely used in the power grid. Currently, there are various methods for monitoring equivalent ice thickness at home and abroad, including the tilt angle method, weighing method, image equivalent discrimination method, meteorological method, etc. Video monitoring is an important means and method for online monitoring of transmission lines. In recent years, it has been widely used in monitoring ice thickness of transmission lines, monitoring against external damage, and monitoring wildfires. As a more intuitive monitoring method, video monitoring has an irreplaceable role. However, in practical applications, the outer protective cover of the camera core in video monitoring devices often forms condensation and ice due to high humidity and low temperature environment, resulting in blurry images. Regarding the tilt angle method, various manufacturers and power grid companies have not conducted much research. The difficulties in this monitoring mode, such as sensor energy harvesting technology and sensor sampling strategy technology, have not been truly overcome. The existing tilt angle method ice monitoring devices on the market are also relatively immature. Therefore, there is a need for online monitoring devices for ice melting of conductors (ground wires).

[0003] Existing wire-based online monitoring devices for ice melting and observation cannot effectively improve the real-time information transmission effect, the performance of continuous monitoring, or the ease of installation. Therefore, there is an urgent need for wire-based online monitoring devices for ice melting and observation. Utility Model Content

[0004] Based on this, the purpose of this utility model is to provide an online monitoring device for ice melting and observation using a conductor (ground wire) to solve the problems that existing online monitoring devices for ice melting and observation cannot effectively improve the real-time information transmission effect, the continuous monitoring performance, and the ease of installation.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an online monitoring device for ice melting of conductors, comprising a base housing, a support shaft installed at one end of the base housing, a roof-shaped top shell installed at one end of the support shaft, a fixing screw installed at one end of the roof-shaped top shell, a compaction ring installed at the lower end of the roof-shaped top shell, and a wire temperature sensor installed in the middle of the compaction ring.

[0006] A solar panel is installed on the upper part of the roof shell, a CT sensor is installed on the inner end of the roof shell, and a slot is opened on the inner end of the roof shell, with a current sensor installed inside the slot.

[0007] An intelligent PID heating plate is installed inside the base housing, a high-precision tilt sensor is installed inside the base housing, an anti-icing camera is installed outside the roof housing, an air temperature and humidity sensor is installed outside the roof housing, and a signal transmitter is installed inside the slot.

[0008] Preferably, the roof shell forms a rotating structure with the base sleeve through the support shaft, and the roof shell is threadedly connected to the base sleeve through the fixing screw.

[0009] Preferably, the compression ring is engaged with the roof shell, and the wire temperature sensor is engaged with the compression ring.

[0010] Preferably, the solar panel is snapped into the roof shell, and the solar panel is arranged symmetrically about the central axis of the roof shell.

[0011] Preferably, the current sensor is connected to the roof shell via a slot, and the outer surface of the CT sensing device is in close contact with the inner surface of the roof shell.

[0012] Preferably, the high-precision tilt sensor is threadedly connected to the base housing, and the intelligent PID heating plate is symmetrically arranged with respect to the central axis of the base housing.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. This utility model uses a base housing, a roof shell, a high-precision tilt sensor, an anti-icing camera, an air temperature and humidity sensor, and a signal transmitter. The entire icing process is observed by lighting lights at both ends of the roof shell combined with the anti-icing camera positioned opposite each other. The air temperature and humidity sensor detects the external air conditions in real time. When the detected wire is icy and tilted, the high-precision tilt sensor can sense and provide feedback in time. At the same time, the detected information is transmitted to the base station in time through the signal transmitter so as to arrange maintenance and repair work and improve the real-time information transmission effect of the device.

[0015] 2. This utility model, through the setting of a base shell, solar panel, CT sensor, and intelligent PID heating plate, allows the entire device to be continuously powered by the solar panel and CT sensor simultaneously. When the device is placed in a low temperature environment, the intelligent PID heating plate is activated to melt the ice around the device, preventing the wires from being covered with ice and seriously affecting the detection effect, thus improving the device's continuous monitoring performance.

[0016] 3. This utility model uses a base sleeve bearing shaft, a roof shell, a fixing screw, a compression ring, and a wire temperature sensor. The compression ring groove on the base sleeve is fitted to the surface of the wire installation location. Then, the roof shell is rotated through the bearing shaft, so that the inner surface of the compression ring on the roof shell is tightly pressed against the surface of the wire. The fixing screw is used on the other side to fix the position of the roof shell and the base sleeve. At this time, the wire temperature sensor contacts the wire and performs real-time sensing. The compression of the compression ring prevents the entire device from sliding, improving the ease of installation. Attached Figure Description

[0022] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0023] The embodiments of this utility model will be described below based on its overall structure.

[0024] Please see Figure 1-4The online monitoring device for ice melting via conductor includes a base housing 1, a support shaft 2 installed at one end of the base housing 1, a roof-shaped shell 3 installed at one end of the support shaft 2, a fixing screw 4 installed at one end of the roof-shaped shell 3, a compaction ring 5 installed at the lower end of the roof-shaped shell 3, and a wire temperature sensor 6 installed in the middle of the compaction ring 5. The roof-shaped shell 3 and the base housing 1 form a rotating structure through the support shaft 2, and the roof-shaped shell 3 is threadedly connected to the base housing 1 through the fixing screw 4. The compaction ring 5 is engaged with the roof-shaped shell 3, and the conductor... The wire temperature sensor 6 is engaged with the compression ring 5. The groove of the compression ring 5 on the base housing 1 is then aligned with the surface of the wire installation location. The roof housing 3 is then rotated via the support shaft 2, causing the inner surface of the compression ring 5 on the roof housing 3 to press tightly against the surface of the contact wire. On the other side, the position of the roof housing 3 and the base housing 1 is fixed using the fixing screw 4. At this time, the wire temperature sensor 6 contacts the wire and performs real-time sensing. The compression of the compression ring 5 prevents the entire device from sliding, improving the ease of installation.

[0025] Please see Figure 1-4 The online monitoring device for ice melting of conductors includes a solar panel 7 installed on the upper part of a roof shell 3, a CT sensor 8 installed inside the roof shell 3, a slot 14 inside the roof shell 3, and a current sensor 9 installed inside the slot 14. The solar panel 7 is connected to the roof shell 3 by a snap-fit, and the solar panel 7 is symmetrically arranged around the central axis of the roof shell 3. The current sensor 9 is connected to the roof shell 3 by the slot 14, and the outer surface of the CT sensor 8 is in close contact with the inner surface of the roof shell 3. The entire device is continuously powered by the solar panel 7 and the CT sensor 8. When the device is placed in an excessively low temperature environment, the intelligent PID heating plate 10 is activated to melt the ice around the device, preventing the conductors from being severely iced and affecting the detection effect, thus improving the device's continuous monitoring performance.

[0026] Please see Figure 1-4The online monitoring device for ice melting of conductors includes an intelligent PID heating plate 10 installed inside the base housing 1, a high-precision tilt sensor 11 installed inside the base housing 1, an anti-icing camera 12 installed outside the roof housing 3, an air temperature and humidity sensor 13 installed outside the roof housing 3, and a signal transmitter 15 installed inside the slot 14. The high-precision tilt sensor 11 is threadedly connected to the base housing 1, and the intelligent PID heating plate 10 is symmetrically arranged around the central axis of the base housing 1. The entire ice-covering process is observed through the lighting lights at both ends of the roof housing 3 and the anti-icing camera 12 positioned opposite each other. The air temperature and humidity sensor 13 detects the external air conditions in real time. When the monitored conductor is covered with ice and tilts at an angle, the high-precision tilt sensor 11 can sense and respond in time. At the same time, the detected information is transmitted to the base station in time through the signal transmitter 15 so as to arrange maintenance and repair work and improve the real-time information transmission effect of the device.

[0027] Working Principle: In use, first, the groove of the compression ring 5 on the base housing 1 is aligned with the surface of the wire installation location. Then, the roof housing 3 is rotated via the support shaft 2, causing the inner surface of the compression ring 5 on the roof housing 3 to tightly press against the wire surface. On the other side, the fixing screw 4 is used to secure the positions of the roof housing 3 and the base housing 1. At this time, the wire temperature sensor 6 contacts the wire for real-time sensing. The compression of the compression ring 5 prevents the entire device from sliding, improving the ease of installation. The entire icing process is observed through the lights at both ends of the roof housing 3 and the opposing anti-icing camera 12. Meanwhile, the air temperature and humidity sensor 13 monitors the external air conditions in real time. When the detected wire is icy and tilted, the sensor detects the icing. When a problem occurs, the high-precision tilt sensor 11 can sense and provide feedback in a timely manner, and simultaneously transmit the detected information to the base station through the signal transmitter 15 so as to arrange maintenance and repair work. The CT sensing device 8 is covered by the semi-open roof shell 3 and the base shell 1, and is closed and installed as the shell opens and closes. The entire device is continuously powered by the solar panel 7 and the CT sensing device 8. When the device is placed in a low temperature environment, the intelligent PID heating plate 10 is activated to melt the ice around the device to prevent the wires from being covered with ice and seriously affecting the detection effect, thus improving the continuous monitoring performance of the device. This completes the use of the device. The contents not described in detail in this specification are existing technologies known to those skilled in the art.
