It is required to develop micro-machine for inspection and maintenance of defects inside small pipe withdiameter smaller than one inch. Considering the advantages of electromagnetic actuators with simple mechanism,high response, convenience to control and fabricate, we tried to develop a new micro-robot in small pipe based on in-teraction principle of electromagnetic attraction and spring force. This paper describes its structure and design. Thedimension of the prototype is diameter of 15 mm, length of 30 mm and weight of 25 g. It can climb in small pipe ofdiameter of 20 mm with a speed of 6～8 mm/s in horizontal or in vertical situation.  相似文献

The micro robot based on screw motion wheels, which features high payload/mass ratio, fast and continuous motion, adaptation to pipe diameter or roundness variations, is suitable for locomotion and inspection inside small-diameter pipelines. The robot inspection system, Tubot I, developed at Shanghai University is composed of locomotion mechanism with an inner motor, a micro CCD camera and a monitor outside the pipeline. In the paper, the kinematics and statics analyses are presented for the screw locomotion system of Tubot I. The moving characteristics are obtained from experiments on the robot prototype.

INTRODUCTION Oil and water well is an important basic estab- lishment in oilfields. In many oilfields, there are many different damages in the well’s casing walls after its development for a period of time. They will affect the normal production of damaged wells and adversely influence the neighbouring wells and the block, and threaten steady production. There are different kinds of damages due to multiple problems in the casing walls, for example, corrosion, perforation, decreased diame…  相似文献

This paper focuses on the heat transfer performance of semi-open heat pipe which is a new type of heat pipe. After analyzing its condensation heat transfer mechanisms theoretically, several semi-open heat pipes in different length ratios and upper hole diameters are studied experimentally and compared with the same dimensions closed heat pipes. Experimental results show that the heat transfer performance of semi-open heat pipe becomes better by increasing heat transfer rate. At the first transitional point, the heat transfer performance of semi-open heat pipe approaches the level of the closed heat pipe. It is suitable to choose upper small hole about 1 mm in diameter and length ratio larger than 0.6 for the semi-open heat pipe.  相似文献

Simulation investigation on fluid characteristics of the water hydraulic jet pipe servo valve (WHJPSV) is conducted through a commercial computational fluid dynamics (CFD) software package FLUENT. In particular, the factors to fluid characteristics of WHJPSV are addressed, which include diameter combination of jet pipe and receiver pipe, jet pipe nozzle clearance, angle between two jet receiver pipes and deflection angle of the jet pipe. It is concluded from the results that: (i) Structural parameters have ...  相似文献

This paper describes a novel design for the carrier mechanism of a pipe-inspection micro robot. Based on this mechanism, a new micro robot for the pipes with diameter of 20mm has been developed. It can travel through both vertical pipes and curved pipes to make possible inspection that would be difficult with conventional endoscopes. This mechanism is composed of three units, two novel micro mechanisms called as a planetary wheel mechanism for robot drive, two micro electromagnetic motors and a flexible coupler.  相似文献

If the measuring signals were input to the chaotic dynamic system as initial parameters, the system outputs might be in steady state, periodic state or chaos state. If the chaotic dynamic system outputs controlled in the periodic states, the periodic numbers would be changed most with the signals. Our novel method is to add chaotic dynamic vibration to the measurement or sensor system. The sensor sensitivity and precision of a measurement system would be improved with this method. Chaotic dynamics measurement algorithms are given and their sensitivity to parameters are analyzed in this paper. The effects of noises on the system are discussed.
