A sma-based inspection four-wheel drive vehicle

Abstract

The invention relates to the technical field of water surface inspection devices, and specifically discloses a four-wheel drive vehicle for inspection based on SMA, which includes a chassis and a cover fixed on the top of the chassis. The two ends are rotatably connected with the chassis and extend to the outside of the chassis. The two ends of the crankshaft assembly are connected with wheels. The bottom of the cover is provided with a plurality of piston cylinders. Pistons are movable in the piston cylinders. The top of the top is provided with a fixed plug, an SMA spring is arranged between the piston and the fixed plug, the bottom of the piston is hinged with a connecting rod, and the other end of the connecting rod is hinged with the crank pin journal of the crankshaft assembly; the chassis There is a patrol device at the bottom. The invention has the advantages of light and compact structure, convenient disassembly and assembly, reconfigurable crankshaft assembly and high interchangeability, combined with SMA spring drive, its power-to-weight ratio is large, and it can work for a long time in a humid environment, with a high degree of automation. Strong ability to adapt to the environment.

Description

technical field [0001] The invention relates to the technical field of water surface inspection devices, in particular to an SMA-based four-wheel drive inspection vehicle. Background technique [0002] With the development of industrialization process, water pollution is becoming more and more serious, which has aroused widespread attention of the society. Caring for and caring for water resources, regularly testing water quality, and preventing erroneous events are what society needs. Regular testing of water quality is a long-term repetitive task. Water quality monitoring in large waters such as rivers and lakes usually involves fixed installation of some water quality monitoring equipment in these waters to specifically monitor the water quality at these fixed locations, and the cost is relatively low. High, unable to complete the water quality monitoring of the entire water area, so that the accuracy of the monitoring results is not enough; there are also some unmanned ...

Regular testing of water quality is a long-term repetitive task. Water quality monitoring in large waters such as rivers and lakes usually involves fixed installation of some water quality monitoring equipment in these waters to specifically monitor the water quality at these fixed locations, and the cost is relatively low. High, unable to complete the water quality monitoring of the entire water area, so that the accuracy of the monitoring results is not enough; there are also some unmanned surface monitoring ships on the market, but their structures are complex, and working in a humid environment for a long time is likely to cause damage to the internal motors and other devices. damage, resulting in short service life
