[0002] The intertidal zone is an area where marine and terrestrial ecosystems interact. Jiangsu Province has Haizhou Bay in the north, Lushi Fishery in the south, and the South Yellow Sea radiating sand ridges in the center. Most of the intertidal zone is muddy coastal flats with rich biological resources.
[0003] At present, biological surveys in intertidal zones are mainly carried out manually by staff walking, using ox carts, tractors and other means of transportation, and arriving at sampling points. However, some intertidal zone muddy sections are severely silted and have low bearing capacity of the foundation, making it difficult for both staff and ordinary vehicles to move forward, especially when encountering bad weather.
[0004] Large benthic animals are an important part of the biological resources in the intertidal zone. Their resources, population distribution, biodiversity and other conditions are closely related to the balance of the marine ecosystem. It is particularly important to conduct regular surveys of benthic animals in the intertidal zone. Summary of the invention

[0009] As a preference, it further comprises a rectangular ring-shaped chain arranged on the edge of the carriage, N airbag bearings and N vertical shafts; N / 2 airbag bearings are evenly distributed on the front edge of the carriage, and another N / 2 airbag bearings are evenly distributed on the rear edge of the carriage, the N airbag bearings are respectively fixedly connected to the lower ends of the N vertical shafts, the airbag sprockets arranged on the lower part of each vertical shaft are meshed with the ring-shaped chain, and the upper ends of the N vertical shafts are respectively fixedly connected to the lower ends of the N airbags;

[0013] A method for using an intertidal zone sampling device comprises the following steps:
[0014] In the initial state, each airbag is filled with hydrogen at a pressure of P;
[0015] Step 5-1, when the staff drives the sampling vehicle in the intertidal zone, if the track sinks into the mud of the intertidal zone, the staff controls the control knobs corresponding to the M airbags that can drive the sunken part of the track to rise, M<N, so that hydrogen enters the M airbags, and each air pressure sensor detects the air pressure in each airbag. The staff observes the air pressure in each airbag displayed on the display, and adjusts the hydrogen intake of the M airbags according to the balance of the sampling vehicle.
