In practical applications, fluid samplers have a wide range of applicability. Whether it is used to assess water quality and track pollution sources in environmental monitoring, or to analyze formation fluids and assess resource reserves in geological exploration, fluid samplers can play an important role.

[0003] With the continuous development of science and technology, fluid sampling technology plays an increasingly important role in environmental monitoring, resource exploration, scientific research and other fields. However, traditional fluid samplers can only collect and store fluid samples in a single way, and cannot meet the needs of sampling at multiple different locations or different depths at the same location at the same time. This limitation leads to low sampling efficiency and easy cross-contamination between samples, which affects the accuracy of subsequent analysis results. Therefore, we need to propose a fluid sampler with multi-space storage. Utility Model Content

[0021] See also Figure 1-4 , the utility model provides a technical solution:

[0022] A fluid sampler with multi-space material storage, comprising a storage tube 1, wherein the storage tube 1 has four groups of accommodating chambers 2 in an annular array, wherein the four groups of accommodating chambers 2 are respectively slidably connected with piston rods 3, and a power assembly 4 for moving the piston rod 3 is arranged at the top of the storage tube 1, and a positioning ring 5 is arranged at the moving end of the power assembly 4, and a connecting plate 6 is fixedly connected to the outer wall of the positioning ring 5, and the top ends of the four groups of piston rods 3 are respectively fixedly connected with fixing seats 7, and the connecting plates 6 are fixedly connected to the fixing seats 7 at corresponding positions by fixing screws. The utility model connects the connecting plates 6 with different fixing seats 7, thereby driving the corresponding piston rods 3 to move by the power assembly 4, and then sampling operations can be performed on different fluid samples, and different fluid samples can be stored in different accommodating chambers 2, which can effectively solve the risk of cross infection between fluid samples;

[0023] The power assembly 4 includes a ball screw 401, the bottom end of the ball screw 401 is rotatably mounted on the top of the storage tube 1, a mounting plate 402 is provided above the storage tube 1, the top end of the ball screw 401 is rotatably connected to the bottom end of the mounting plate 402, and the top end of the ball screw 401 penetrates the mounting plate 402 and is connected to a driving motor 403, a moving block 404 is threadedly connected on the outer wall of the ball screw 401, and a positioning ring 5 is rotatably sleeved on the outer wall of the moving block 404;

[0024] Specifically, the ball screw 401 is driven to rotate by the output shaft of the driving motor 403, thereby driving the moving block 404 to reciprocate along the axial direction of the ball screw 401, and then driving the piston rod 3 to move through the connecting plate 6 and the fixing seat 7;

[0025] It is worth mentioning that the bottom of the mounting plate 402 is fixedly connected with four groups of support rods 8 in a circular array, and the bottom ends of the four groups of support rods 8 are fixedly connected to the top of the storage tube 1. The outer wall of the moving block 404 is fixedly connected with four groups of sliders 9 in a circular array, and the four groups of sliders 9 are slidably connected to the four groups of support rods 8 respectively. By setting the support rods 8 and the sliders 9 for use in coordination, the moving block 404 is limited, making it more stable during operation.
