Description

Technical Field

[0001] The invention relates to the technical field of water ecology sampling, and in particular to a field multifunctional water ecology survey sampling and detection vehicle. Background Art

[0002] Water ecological sampling refers to the collection of samples from water bodies in order to analyze biological, chemical, physical and other factors in order to assess the ecological environment quality of the water body. The purpose of water ecological sampling is to monitor the pollution status of water bodies, promptly identify water quality problems, protect the water ecosystem, and provide a scientific basis for the formulation of relevant environmental protection policies.

[0003] In water ecological sampling, it is usually necessary to collect multiple types of samples, such as water samples, sediment samples, biological samples, etc. Water samples are mainly used to measure water quality parameters, such as temperature, pH value, oxygen content, etc. Sediment samples can be used to measure sediment particle size, heavy metal content, nutrient content, etc. Biological samples can be used to measure indicators such as the number of aquatic organisms, population structure and biodiversity.

[0004] Existing water environment sampling devices mostly use surface vessels to sail from the water surface to the sampling area for sampling. The water-based sampling devices must be placed on the water surface to work, which is time-consuming and labor-intensive. The speed of surface navigation is also slow, which reduces the sampling efficiency. The existing water ecological sampling devices can complete relatively single sampling projects, and the sampled samples are not comprehensive enough. Therefore, a field multifunctional water ecological survey sampling and detection vehicle is needed. Summary of the invention

The steering device and the propulsion device cooperate to stabilize the submersible at a relatively fixed sampling point on the water; water sampling devices are fixedly connected to the left and right sides of the front end of the aircraft body, a flight control device is fixedly connected to the middle part of the front end of the aircraft body, a battery is fixedly connected to the bottom of the flight control device, a flying camera is fixedly connected to the front end of the aircraft body, an underwater camera is fixedly connected to the middle part of the aircraft body, a silt sampling device for collecting silt and a grass sampling device for collecting grass samples are fixedly connected to the rear end of the aircraft body, the remote control is wirelessly connected to the flight control device, and a sensor assembly is fixedly connected to the bottom of the aircraft body.

[0007] Furthermore, the inflatable warehouse includes a warehouse body and a compressed gas cylinder.

The air outlet of the vacuum pump 1 is fixedly connected to the compressed gas cylinder through a conduit, and a control valve 2 is provided at the connection point.

[0008] Description: The air chamber is inflated to make the aircraft float on the water surface, and the vacuum pump sucks the air in the air chamber into the compressed gas cylinder, the buoyancy of the aircraft is reduced, and it dives. The above structure can repeatedly float up and dive.

[0009] Furthermore, the water sampling device includes a sampling chamber and a water suction pump. There are multiple sampling chambers, and the multiple sampling chambers are respectively fixedly connected to the body. A water sample bottle is detachably fixedly connected inside the sampling chamber. A bottle cap is provided on the top of the water sample bottle. A water sample tube is connected to the bottle cap, and a control valve three is provided at the connection. The water suction pump is fixedly connected to the inside of the body, and the water outlet of the water suction pump is fixedly connected to each water sample tube through a conduit. The water inlet of the water suction pump is fixedly connected to a pipette, and the lower end of the pipette is connected to the outside of the body.

[0010] Description: Water at different depths is sampled through the water suction pump in the water sampling device, and the water samples are sucked into the water sample bottle to facilitate the collection of water samples.

[0011] Furthermore, the sludge sampling device includes a mud bin and a reel. There are multiple mud bins, which are fixedly connected to the inside of the machine body. A vacuum pump 2 is fixedly connected to the top of the mud bin, and the air outlet of the vacuum pump 2 is fixedly connected to the outside of the machine body. The bottom of the mud bin is fixedly connected to a mud sampling pipe, and a control valve 4 is provided at the connection. The other end of the mud sampling pipe is connected to the reel, and the reel is installed in the machine body.

[0017] The beneficial effects of the present invention are:

[0018] (1) Compared with the sampling device on the water surface, this device adopts a quad-rotor structure to quickly approach the sampling area by flying, which saves more time than the sampling device on the water surface. When the device performs multiple sampling at the sampling point, it can float on the water surface for navigation. When sampling the bottom silt, the device can be controlled to dive to the sampling point for silt sampling. It can also collect water samples at different depths. During the sampling process, the device can also record the water temperature, transparency, turbidity, oxygen content, pH value, salinity, and water depth, and then transmit the data back in real time.

When carrying it back, it can float up by inflating the air chamber. After floating up, it can fly back to the starting point through the four flying wings. The samples collected are of various types and rich in effective information, which can provide a comprehensive understanding of the water ecological environment. It can also effectively save sampling time, improve sampling efficiency, and reduce sampling difficulty. BRIEF DESCRIPTION OF THE DRAWINGS
