An anti-jamming hammer mechanism

Abstract

The invention discloses an anti-interference heavy hammer mechanism, and aims to provide an anti-interference heavy hammer mechanism which can effectively solve the problem that the quality of a collected water sample is affected as muddy water is excited when a heavy hammer touches the bottom. The anti-interference heavy hammer mechanism comprises a main supporting rod, a trigger expansion type buffering umbrella arranged on the main supporting rod, a triggering device and a main balance weight, wherein the main balance weight is positioned below the trigger expansion type buffering umbrella; a longitudinal shaft hole penetrating through two end faces of the main supporting rod are formed in the main supporting rod; the trigger expansion type buffering umbrella comprises a sliding sleeve sleeving the main supporting rod in a sliding manner, a plurality of main umbrella keels uniformly distributed at the circumferential direction of the main supporting rod, a plurality of auxiliary umbrella keels corresponding to the main umbrella keels one by one and an umbrella surface arranged on the main umbrella keels; the upper ends of the main umbrella keels are hinged to the upper part of the main supporting rod; one end of each auxiliary umbrella keel is hinged to the sliding sleeve, and the other end of each auxiliary umbrella keel is hinged to the middle part of the corresponding main umbrella keel; and an outer limiting stop block is arranged on the outer side surface of the main supporting rod and is positioned above the sliding sleeve.

Description

technical field [0001] The invention relates to a heavy hammer device applied to a water sample collector, in particular to an anti-interference heavy hammer mechanism applied to a water sample collector. Background technique [0002] In a large number of scientific research and marine environmental monitoring work, it is usually necessary to collect a certain amount (depending on project requirements) of bottom seawater for bottom water quality (including pH value, dissolved oxygen, phosphate, inorganic nitrogen, heavy metals, etc.) or Analysis of plankton (including zooplankton and phytoplankton), etc. Bottom seawater generally refers to seawater at a depth of 2 meters (or 0.5 meters from the seabed) (GB17378.3-2007 "Marine Monitoring Specification Part 3: Sample Collection, Storage and Transportation" stipulates that the maximum It is best to take the water layer 2 meters away from the seabed, and the distance from the bottom layer can be increased as appropriate in deep...
