Underwater sludge thickness measuring device

Abstract

The invention relates to the technical field of underwater soil sampling, in particular to an underwater sludge thickness measuring device which comprises a bottom plate. Float bowls are mounted at the periphery of the bottom surface of the bottom plate, an emptying hole is formed in the center of the top surface of the bottom plate, and a supporting mechanism is fixedly connected to the position, located at one side of the emptying hole, of the top surface of the bottom plate. The supporting mechanism comprises a support, the bottom end of the support is fixedly connected with the bottom plate, and the top end of the support is rotationally connected with a fixing disc. According to the present invention, through the arrangement of a first rack, a second rack and a fixing frame, a percussion drill can only move in a single direction, so that continuous progression of the percussion drill is achieved, and a sampling rod is gradually hammered into soil below sludge; meanwhile, the percussion drill does not need to be supported and pressed by hands, and the workload of a user is relieved; through the arrangement of a clamping groove, a fixing disc and a fixing rod, the fixing disc is rotated to enable a sliding mechanism and the percussion drill to be inverted, so that the moving direction and the percussion direction of the percussion drill are changed, and the sampling rod is conveniently taken out of sludge.

Description

technical field [0001] The invention relates to the technical field of underwater soil sampling, in particular to an underwater mud thickness measuring device. Background technique [0002] In some deep waters such as reservoirs and lakes, the underwater silt thickness is relatively thick. When measuring the underwater silt thickness in these waters, it is necessary to use a drill pipe to perform columnar sampling of the underwater soil to measure the thickness of the underwater silt layer. [0003] The existing drilling sampling measurement device needs to be pressed and supported by the user during use. At the same time, it is difficult to pull out the drill pipe after it is inserted into the ground. The existing drilling sampling measurement device can only rush the drill pipe into the ground, but cannot realize To take out the drill pipe from the underwater mud, other hoisting tools are needed, which is troublesome and inconvenient to use.
