Problems solved by technology

The plankton net is designed as a submerged net, and the diameter of the net mouth is small. It is difficult to control the attitude when sampling the surface water body, and it is difficult to ensure the accuracy of sampling.
However, the existing design of microplastic surface water trawl nets has high requirements on ship speed, sea conditions, net gear launch position and other conditions, and can only sample surface water bodies, and is powerless to collect microplastic samples within a certain water depth range.
At present, there is a lack of a device with a certain degree of automation that is suitable for collecting samples of water quality, plankton and microplastics in water bodies within a certain depth range

Embodiment 1

[0034] Embodiment 1, see attached Figure 1-5, a multifunctional water body sample collector, comprising a closed box body 1, the box body is made of a resin material or a metal three-dimensional rectangular airtight box body, and a rechargeable battery 2 and a water pump 3 are fixed in the cavity of the box body 1. The first DC motor 4 powered by the rechargeable battery drives the water pump 3, the water inlet of the water pump 3 is connected to the water inlet pipe 31, the water outlet of the water pump 3 is connected to the water outlet pipe 32, and the water inlet pipe 31 is sealed through the box body The corrugated pipe 5 is connected behind the bottom plate of the tank, and the outlet pipe 32 is sealed to pass through the top plate of the box body and then connected to the delivery hose 6. The delivery hose is a long rubber hose with high temperature resistance and aging resistance, and both ends are equipped with There is a rubber sealing ring and a connecting screw, ...

Embodiment 2

[0036] Embodiment 2, others are the same as Embodiment 1, the difference is that the center of the four side plates of the box body 1 is respectively fixed with a second DC motor 15, and the output shaft of each of the second DC motors 15 is sealed through the box. A propeller 16 is fixedly connected behind the body tail plate; a control handle 17 is also included, and the control cable connected to the control handle 17 is sealed and passed through the top plate of the box body to be connected with the controller fixed in the cavity, and the control handle 17 The buttons on the top can control the first DC motor to control the start and stop of the water pump 3, and respectively control the speed and steering of the second DC motor 15. Turning to the left or right can be realized, so that the device can move autonomously in the water body.

Embodiment 3

[0037] Embodiment 3, others are the same as Embodiment 2, the difference is that the remote control handle is used instead of the control handle, and controllers that are respectively connected to the first DC motor and the second DC motor and can receive the wireless control signal of the remote control handle are arranged in the cavity. The buttons on the wireless control handle can control the start and stop of the water pump 3, and respectively control the speed and steering of the second DC motor 15. In this way, the handling is more flexible and the maneuverability is better.

Abstract

The invention discloses a multifunctional water sample collector, comprising a closed box body. A rechargeable battery and a water pump are fixed in the cavity of the box body. The water pump is driven by a first direct current motor. A water inlet of the water pump is connected with a water inlet pipe, and a water outlet of the water pump is connected with a water outlet pipe. The water inlet pipe is connected with a corrugated pipe after hermetically passing through a bottom plate of the box body. The water outlet pipe is connected with a conveying hose. The free end of the conveying hose can be screwed into a set of sample bottles that can collect different types of samples. Telescopic rods are symmetrically arranged on the outer surface of the bottom plate of the box body and outside the corrugated pipe. The free ends of the telescopic rods are fixedly connected with a connecting plate. The free end of the corrugated pipe is fixedly connected to the middle of the connecting plate.The corrugated pipe can be driven by the two telescopic rods to extend and retract, and can be driven by two joint balls to form different angles with the bottom plate of the box body. A float is fixedly connected to the middle of the top plate of the box body. A fixed ring is arranged at the upper end of the float. A traction rope is tied to the fixed ring. The device is simple in structure and easy to assemble and disassemble.

Description

technical field [0001] The invention relates to the field of marine surveys, in particular to a device for automatically collecting samples of water quality, plankton and microplastics within a certain water depth range. Background technique [0002] Most of the earth's surface is covered by oceans. Oceans are an important part of the human life support system, a regulator of global climate change, and a valuable asset and strategic space for the sustainable development of coastal countries around the world. With the development of the times and the advancement of science and technology, human beings have gradually deepened their understanding of the value of the ocean and its role. The development and utilization of the ocean is developing in a diversified direction, and the awareness of ocean protection is also increasing. [0003] At present, the routine monitoring indicators for marine water quality mainly include pH, dissolved oxygen, chemical oxygen demand, salinity, i...
