Problems solved by technology

[0002] At present, in most areas of our country, underground pipeline laying projects such as municipal, telecommunications, electric power, oil, natural gas, gas, tap water, heat, sewage, etc. still use manual or mechanical equipment to open trenches and bury pipes. Serious environmental pollution, poor construction safety, low precision of pipe laying, frequent traffic jams, labor-intensive and time-consuming operation costs are greatly increased, which is very uneconomical

Abstract

The stabilized voltage supply is composed of DC voltage increase module, Pi type filter circuit, and DC voltage regulation module. DC voltage increase module is voltage regulation circuit of providing high DC voltage output from low DC voltage input. High DC voltage output through Pi type filter circuit is input to DC voltage regulation module circuit. Output regulated voltage supplies voltage in long time, low temp drift, high accuracy from two batteries in 1.5V, providing required working voltage for probe.

Description

technical field [0001] The invention relates to a stabilized power supply. In particular, it relates to a low-temperature drift, high-precision boosting and stabilizing power supply in a non-excavation horizontal drilling hole in a trenchless horizontal drilling hole for laying an underground pipeline project without digging a trench on the ground surface. Background technique [0002] At present, in most areas of our country, underground pipeline laying projects such as municipal, telecommunications, electric power, oil, natural gas, gas, tap water, heat, sewage, etc. still use manual or mechanical equipment to open trenches and bury pipes. Serious environmental pollution, poor construction safety, low precision of pipe laying, frequent traffic jams, labor-intensive and time-consuming operation costs are greatly increased, which is very uneconomical. Therefore, a trenchless pipe laying technology, that is, a construction technology for laying and r...
