Problems solved by technology
[0005] The purpose of the present invention is to overcome the sediment sampling device on the substrate of the seabed rock reef in the prior art that usually only can collect the sediment of the surface layer, making it difficult to evaluate more accurately the composition and source of the sediment on the seabed rock reef; and cannot The problem of effectively assessing the deposition level of sediments on seabed rocks; providing a near-shore seabed suction mud extractor, which can randomly collect completely the sediments on a certain part of the seabed on rocks, Efficiently assess sediment deposition levels and provide samples for accurate assessment of sediment composition and origin on reef substrates

Embodiment Construction
[0025] Below in conjunction with accompanying drawing and specific embodiment the present invention is described in further detail:
[0026] Such as figure 1 , figure 2 , image 3 As shown, a nearshore seabed suction dredger includes a water pump 24, a sediment collection container 23, a support frame, a cylindrical collection box 3 and a jacket 13 sleeved on the collection box. The support frame includes four support columns uniformly distributed around the circumference of the collection box and a top frame 2 arranged on the top of the support column. The support column is composed of an upper support column 1a, a lower support column 1b and an elastic connection structure connecting the upper and lower support columns. The elastic connection structure includes an upper support plate 104 fixed on the lower end of the upper support column, a lower support plate 101 fixed on the upper end of the lower support column, and a prestressed spring 103 arranged between the upper ...

The invention discloses an off-shore seabed suction-type sludge sampler. The objective of the invention is to provide the suction-type sludge sampler which can randomly and completely acquire sediments on cay at a certain part of a seabed so as to effectively assess the deposition level of the sediments and provide samples for accurate assessment of composition and sources of the sediments on a cay matrix. The off-shore seabed suction-type sludge sampler comprises a bracing frame, a cylindric acquisition cover body and a coat sleeving the acquisition cover body, wherein the lower end of the acquisition cover body is opened, the upper end of the acquisition cover body is enclosed, the bracing frame comprises at least three supporting columns and a top rack, the top of the acquisition cover body is provided with a connection shaft sleeve, a connection shaft is arranged in the connection shaft sleeve, the top rack is provided with a driving motor driving the connection shaft to rotate, the coat is connected with the supporting columns through connecting rods, the inner side surface of the coat is provided with an annular groove, a plurality of through holes are arranged in the side surface of the acquisition cover body facing the annular groove, and the outer side surface of the coat is provided with a suction port communicated with the annular groove.
Description
technical field [0001] The invention relates to a collection device, in particular to a nearshore seabed suction dredger. Background technique [0002] Due to the impact of human activities, the amount of sediment (bottom mud) in the near-shore rocky submarine reef area has been increasing, which has seriously affected the composition and biomass of benthos living on the lithofacies matrix. Therefore, the research on sediments (sediment) on lithofacies matrix has gradually been paid attention to, especially the composition and source of sediments (sediment) are particularly important; however, quantitative collection and effective evaluation of sedimentation levels are complex work. For the study of sediment (sediment) on the substrate of seabed rocks, the sediment (sediment) is usually sampled by sampling equipment, and then the amount and type of the sampled sediment (sediment) are evaluated. [0003] Since the current sampling devices for sediments on the substrate of s...
