Autonomous navigation type surface water quality sampling and real-time monitoring water level robot

Abstract

The invention discloses an autonomous navigation type surface water quality sampling and real-time monitoring water level robot. The autonomous navigation type surface water quality sampling and real-time monitoring water level robot comprises a ship body, a power system, a master control system, a navigation system, a communication system, a sampling monitoring system and a propelling system, wherein the power system, the master control system, the navigation system, the communication system, the sampling monitoring system and the propelling system are arranged on the ship body; the navigation system comprises an electronic compass, a GPS (global positioning system), an ultrasonic obstacle-avoiding sensor and a camera, and the navigation system is connected with the master control system; and the sampling monitoring system comprises a water sampling swing rod which is arranged on a steering engine, the water sampling swing rod controls the water sampling depth and is connected with one end of a water sampling pipeline, the other end of the water sampling pipeline is shunted into all sampling bottles from a peristaltic pump to a pinch valve, all sampling bottles are arranged in a heat preservation box, a water quality sensor connected with the master control system is arranged on the water sampling swing rod, and the propulsion mode of the propelling system adopts an externally-mounted double-direct-current motor and a screw propeller. The autonomous navigation type surface water quality sampling and real-time monitoring water level robot has small volume and light weight, can be carried conveniently, can be operated simply, is free of pollution, and can realize sampling monitoring to an area where a person cannot reach.

Description

technical field [0001] The invention relates to the technical field of surface water quality sampling and monitoring, in particular to an autonomous navigation surface water quality sampling and real-time monitoring robot. Background technique [0002] At present, there are two main methods of water quality monitoring, one is online real-time monitoring, and the other is to sample water quality to the laboratory for testing. These two methods have their disadvantages. Online real-time monitoring often has a fixed location, which is inconvenient to detect water samples from other locations. Sampling water quality to the laboratory often requires people to row boats to designated locations to collect water samples. If the sampling water area is large, the water surface environment is complex, and the number of samples to be collected is large, manual sampling is a heavy and inefficient task. And if it is toxic pollution, it will pose a threat to the health of the sa...

These two methods have their disadvantages. Online real-time monitoring is often in a fixed position, and it is inconvenient to detect water samples from other locations.

Sampling water quality to the laboratory often requires people to row boats to designated locations to collect water samples. If the sampling water area is large, the water surface environment is complex, and the number of samples to be collected is large, manual sampling is a heavy and inefficient task.

And if it is toxic pollution, it will pose a threat to the health of the sampling personnel

[0003] In the patent application issued by China with the application number 201010168446.7, when the ship advances out of view, the sampling personnel cannot perceive the water environment where the ship is located in real time. When there are many floating objects on the water surface, the ship will not only fail to operate, but may lost ship

In this patent, the communication system uses GPRS, and GPRS needs to pay to purchase traffic. When the signal is not good, the data delay is large, and the robot cannot be controlled in real time.

In this patent, a hoist is used to retract and unwind the water collection pipeline, and the water pipeline is rolled on the hoist, which will easily bend the water collection pipeline, which will cause the water collection pipeline to be blocked, and the water sample cannot be collected normally; and the electromagnetic valve is used in this patent. The water sample is diverted, and the sampled water will pass through the solenoid valve. The solenoid valve is easy to pollute the water sample or the polluted water sample will corrode the solenoid valve.
