Description

Technical Field

[0001] The invention relates to the technical field of transmission line icing monitoring, and in particular to a novel automatic icing observation device. Background Art

[0002] Due to the multiple impacts of El Nino, La Nina and the Arctic vortex, natural disasters such as severe icing occur frequently. The transmission network is in a natural environment, and ice damage can cause transmission lines to trip, break or even collapse. Accurately and automatically recording the icing conditions near the line is very important for ice zone division and prevention of engineering ice disasters.

[0003] The existing methods for monitoring ice thickness include the inclination method, weighing method, image equivalent discrimination method, meteorological method, etc. The inclination method is to obtain the temperature and inclination of the conductor and use the conductor state equation to infer the icing condition of the conductor; among them, the patent with announcement number CN112484779B discloses a method for monitoring the inclination icing under the force mode of a power line tower, which mainly measures the icing data of the conductor by the inclination method, and installs a conductor temperature and inclination sensor on both sides of the span, collects the characteristic parameters of the conductor to be measured and the line foundation as constants, obtains known state quantities, measures some unknown state quantities, and finally calculates the equivalent icing thickness of the conductor under the unknown state, thereby completing the monitoring of icing thickness;

[0004] The icing monitoring method in the above patent is greatly affected by wind load during implementation, and the actual measured ice thickness lacks reliable data and cannot intuitively reflect the icing situation. At the same time, the automatic observation of conductor or simulated conductor icing by tension sensors in the prior art is also affected by wind load, and the tension sensors connected in series with insulators pose a safety risk. The image equivalent judgment method requires scraping or heating to de-ice in order to obtain icing characteristics, which consumes a lot of energy and cannot meet the power supply needs in the field. Therefore, the present invention proposes a new automatic icing observation device. Summary of the invention

[0005] The purpose of the present invention is to provide a new type of automatic ice observation device, which is used to solve the problems of difficulty in ice observation in power grids and meteorology. The present invention saves the energy consumed by small lens deicing and strengthens the acquisition of actual icing quantitative data to analyze the icing properties of simulated conductors and the accurate average standard icing thickness to achieve observation of the icing conditions of nearby conductors.

[0006] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a new type of automatic ice observation device, including an analog wire, a torque sensor, an optical monitoring module, an energy storage transmission unit and a solar panel, wherein the torque sensor is fixedly arranged at the lower end of a support connecting pipe, a fixing piece is fixedly connected to the surface of the support connecting pipe, a fastening screw is arranged on the surface of the fixing piece, and the fixing piece is fixedly connected to the surface of the tower by the fastening screw; the upper end of the support connecting pipe is fixedly connected to the optical monitoring module.

[0007] Preferably, a soft protective cover and a square fixing bolt are provided on the surface of the torque sensor, the soft protective cover is a cylinder with a through hole at the bottom, and the through hole portion is sleeved on the surface of the torque sensor; a square rotating shaft is fixedly provided on the surface of the torque sensor, one end of the square fixing bolt is fixedly connected to the square rotating shaft, and the other end of the square fixing bolt is fixedly connected to the analog wire.

[0008] Preferably, the optical monitoring module includes an anti-icing cover and a small lens; the small lens seal is placed inside the upper end of the supporting connecting tube, the anti-icing cover seal is placed outside the upper end of the supporting connecting tube, and the anti-icing cover sealing sleeve is arranged on the surface of the small lens.

[0010] Preferably, the simulated wire is fixedly connected to the torque sensor via a square fixing bolt, the weight of ice on the simulated wire is measured by the torque after the torque sensor is stressed, and the ice coating properties are observed via an optical monitoring module.

[0011] The beneficial effects of the present invention are as follows:

[0012] The ice observation device of the present invention is easy to install and can be installed on any pole tower, the ground, or a place where observation is required, and is suitable for ice observation in various scenarios. By installing a simulated wire on the ice observation device, the ice observation device is installed around the wire that needs to be observed, and the weight of ice on the simulated wire is used to infer the torque variable generated by the torque sensor through the simulated wire.

[0013] The present invention uses the weight of ice on a vertical plane to generate a torque increment on a simulated conductor, and measures data through a vertical plane torque sensor, so that the wind load on the horizontal plane has no effect on the vertical plane torque, thereby overcoming the disadvantage that the wind load affects the measurement data during ice measurement in the prior art.

[0025] Working principle: the ice observation device is fixed to the pole tower 1 by means of the fixing part 2 and the fastening screw 3, and the simulated conductor 7 is fixed to the ice observation device, wherein the ice observation device is installed around the conductor to be monitored, the simulated conductor 7 is fixed to the surface of the square fixing bolt 8, the square fixing bolt 8 is fixed to the surface of the torque sensor 5, and the torque sensor 5 is fixed to the lower end of the supporting connecting pipe 4; by vertically connecting the simulated conductor 7 and the torque sensor 5, when ice appears on the surface of the simulated conductor 7, the simulated conductor 7 will be twisted due to the action of gravity, and this change will be monitored in real time by the torque sensor 5 and the data therein will be saved; in this process, even if it is affected by wind load, the horizontal torque generated will not cause obvious deviation to the torque data of the simulated conductor 7 measured vertically, and this design can effectively avoid the adverse effect of wind load in the process of ice monitoring by the torque sensor 5, thereby reducing the measurement data error caused by wind load.
