SMA-driven inspection four-wheel-drive vehicle

Abstract

The invention relates to the technical field of water surface inspection devices and particularly relates to an SMA-driven inspection four-wheel-drive vehicle. The vehicle comprises a chassis and a vehicle cover fixed to the top of the chassis, wherein a crankshaft assembly is arranged at each of the front end and the rear end in the chassis, two ends of the crankshaft assembly are rotationally connected with the chassis and extend out of the chassis, wheels are connected with two ends of the crankshaft assembly, a plurality of piston cylinders are arranged at the bottom of the vehicle cover,pistons are movably arranged in the piston cylinders, fixing plugs are arranged at tops of inner cavities of the piston cylinders, SMA springs are arranged between the pistons and the fixing plugs, connecting rods are hinged to bottoms of the pistons, and the other ends of the connecting rods are hinged to crank pin journals of the crankshaft assembly, and an inspection device is arranged at the bottom of the chassis. The device is advantaged in that the structure is light and compact, and the crankshaft assembly is convenient to disassemble and assemble, reconfigurable, high in interchangeability, large in power-to-weight ratio in combination with SMA spring driving, capable of working in a humid environment for a long time, high in automation degree and high in environment adaptability.

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
