Embodiment Construction

[0028] The present invention will be further elaborated below by means of the accompanying drawings and examples.

[0029] Such as Figure 1-8 Shown: a continuous multi-point water collection device for ocean profiles, including a sampling rack 1, a sampling housing 2 with a movable cover on the sampling rack 1. An adaptive pressure adapter 3 is provided, and the adaptive pressure adapter 3 can drive the sampling housing 2 to rotate as the pressure increases during the submersion process of the sampling rack 1 .

[0030] A plurality of water collection units 4 are radially arranged on the sampling rack 1, and are distributed at an equal angle at the center of the sampling rack 1. The sampling housing 2 is always used for sampling and collection by only one of the water sampling units 4 during the rotation process. 4 includes a collection tube 41 with an open outer end, a valve part 42, and an electric push rod 43 located above the collection tube 41. The sampling rack 1 is pr...

Abstract

The invention discloses a continuous multi-point water sampling device for the ocean profile. The device comprises a sampling frame and a sampling shell movably covering the sampling frame, the sampling frame is in a disc shape, the middle of the sampling frame is through up and down, a self-adaptive pressure adaptation part is arranged on the sampling frame, and the self-adaptive pressure adaptation part can move up and down in the diving process of the sampling frame; a sampling shell is driven to rotate along with the increase of the pressure intensity, and a plurality of water sampling units are radially arranged on the sampling frame and are distributed at equal angles by taking the center of the sampling frame as the center. According to the invention, the sampling units are arrangedto match a plurality of valve pieces, in the electric push rod extending process, a sliding plate is driven to move in the length direction of a limiting plate, in the moving process, two linkage blocks rotate in the opposite directions, then two sealing plates are driven to turn over, and closing of the valve pieces is achieved; and meanwhile, a second spring is arranged in matched mode, in theprocess that the electric push rod continues to extend, the valve pieces can be driven to be closed in sequence from inside to outside, and water samples at the same depth and different water area positions can be collected by each independent sampling chamber.

Description

technical field [0001] The invention relates to the technical field of sampling equipment, in particular to a continuous multi-point water collection device for ocean profiles. Background technique [0002] In the process of marine water quality monitoring, it is necessary to collect seawater and test the collected seawater to judge the quality of marine water. At present, seawater collection generally adopts the method of manual collection. The personnel on board throw the collection tank directly into the sea, connect the pull rope to the collection tank, and then pull up the collection tank filled with seawater to complete the water sample collection at this position. Accuracy requires multi-point sampling, which requires the sampling personnel to repeat the above sampling action many times, which has potential safety hazards, inconvenient sampling operation, and inconvenient collection of water samples at different depths. In order to solve the above problems, this case ...
