Portable on-tower sag observation device

Abstract

The invention discloses a portable on-tower sag observation device, and relates to the technical field of power transmission lines. A telescope assembly is arranged at the outer part of one side of ashell; the housing of the telescope assembly is fixedly connected with the outer end of a main shaft; the inner end of the main shaft is screwed in a shaft sleeve by utilizing a ball; the shaft sleeveis fixed at the inner part of the shell; the inner end of the main shaft is fixedly connected with a grating angle measuring assembly; the grating angle measuring assembly is in electronic control connected with a single chip in a screen assembly; the single chip is connected with a power key and a reset key; both the power key and the reset key are arranged at the outer part of the shell; a display in the screen assembly is embedded in the side wall of the shell; the screen assembly is electrically connected with a battery; and the battery is fixed at the bottom of the shell. Through the setting of the telescope, the scales are clearer, the precision is high and temperatures can be display in real time at the same time, so that benefit is brought to the data statistic, the influences, onthe measuring precision, of the temperatures are avoided and the practicability is higher.

Description

technical field [0001] The invention relates to the technical field of power transmission lines, in particular to a portable sag observation device on a tower. Background technique [0002] The mainstream method of sag observation in transmission line construction is the parallelogram method of binding sag plates for sag observation. This method does not require special tools and devices, and can be implemented by experienced workers. It is more suitable for application in line projects below 220kV. With the large-scale construction of UHV projects, due to the scarcity of auxiliary materials for UHV tower structures, it is difficult to bind sag plates; the large span makes it difficult to observe with the naked eye, resulting in large sag errors And many other problems, there are also many restrictive factors in using the angle method to look at the sag on the ground, so it cannot be popularized. Some enterprises try to research new-type sag observation devices, such as the...

Problems solved by technology

[0003] The purpose of this device is to provide a level ruler for sag observation. Since there is no telescope and vertical angle reading, it has great limitations in use and cannot solve the problem of UHV large-gear sag observation

Since there is no suitable special sag observation device on the tower in the market, and the demand for sag observation in line construction is getting higher and higher, it is necessary to develop a special portable optical sag observation device based on the above reasons
