Embodiment Construction
[0032] A novel steel cable suspended counterweight sediment sampling system of the present invention will be described in detail below in conjunction with the accompanying drawings and embodiments.
[0033] The working principle of the device proposed by the present invention is as follows: figure 1 As shown, the whole sampling system is suspended by releasing a steel cable from the hoist on the survey ship 1, and the support frame 4 and the additional counterweight 3 are clamped on the sampler 2, and when the frame 4 touches the sediment layer 5, it will contact with the sampler 2 Separated, the additional counterweight 3 follows the sampler 2 into the drill.
[0034] Please also refer to figure 2 One embodiment of the novel steel cable suspended counterweight sludge sampling system of the present invention includes a sampler 2, a support frame 4 and an additional counterweight 3, and the sampler 2 includes a drive cylinder, a sampling cylinder, and a drill bit.
