摘要： A suction sampler system for in situ collection of deep-sea floor organisms includes a pressure-retaining cylinder, a pressure compensation device, a cone component, semiconductor refrigeration components, a circuit cylinder and a collection cylinder. Two ends of the pressure-retaining cylinder are respectively equipped with a first and second seal mechanisms, and the cone component is arranged in the pressure-retaining cylinder. The pressure compensation device is connected to the pressure-retaining cylinder through a high-pressure pipe. The semiconductor refrigeration components are arranged outside the pressure-retaining cylinder. The circuit cylinder is equipped with a power supply and a controller, and the semiconductor refrigeration components are connected to the controller. A pressure sensor and a temperature sensor are arranged inside the pressure-retaining cylinder, and respectively connected to the controller. The collection cylinder communicates with the valve hole of the second seal mechanism through a pipeline.
