Embodiment Construction

[0085] A detachable portable drilling and sampling device on water, including a floating platform on water, a lifting impact device for a machine tool, and a sampling machine tool device 13.

[0086] There is a port 12 in the center of the water floating platform.

[0087] The impact device for machine lifting includes a hanger 5 and a hammer 15 .

[0088] The hanger 5 base is fixedly arranged on the floating platform on the water, and the upper part of the hanger 5 is a pulley block 23 . The pulley block 23 includes two fixed pulleys.

[0089] The electric winch 24 is arranged on the floating platform on the water close to the hanger 5, and the hoisting wire rope 25 passes through the hanger 5 and two fixed pulleys of the pulley block 23.

[0090] First, when it is necessary to put the sampling equipment device 13 into the water or put it out of the water, the lower end of the hoisting wire rope 25 is connected to the mounting ring on the upper part of the basket 14, and th...

Abstract

The invention provides a detachable type water-borne portable drilling and sampling device and a sampling method. The detachable type water-borne portable drilling and sampling device comprises a sampling machine device, a machine guide device, a machine hoisting and impacting device and a water-borne platform, wherein a through hole is preformed in the center of the platform; a hanger and a winch are arranged at the periphery of the through hole; the winch drives a drilling rod or a hanging hammer or a pressing plug; and the sampling machine device is provided with a double-layered sleeve and a double-door soil sampler. The double-door soil sampler takes an impacting head as a core and is internally provided with an inward opening arc-shaped door and a water stopping sealing mechanism. The impacting head is impacted through the hanging hammer at the upper part to enter a water bottom soil layer, the inward opening arc-shaped door is automatically opened, and bottom mud enters a sampling inner pipe. When the double-door soil sampler is suddenly hoisted, and the bottom mud in the sampling inner pipe automatically falls off and the inward opening arc-shaped door is closed, so that an underwater original-shape soil sample without water loss and small disturbance is obtained and the structure is simple.

Description

technical field [0001] The patent of the present invention relates to the field of using a drilling machine to drill an underwater formation on a water platform. It particularly relates to a detachable portable drilling sampling device and a sampling method using the device, which can be assembled on water to drill underwater formations and obtain undisturbed muddy core samples. Background technique [0002] Since drilling on the water generally needs to be carried out on a special geological survey ship, the survey ship can also be transformed from an ordinary ship or the drilling rig can be directly installed on the water platform. These survey ships have huge equipment, drill deep underwater formations, and can take core samples of various underwater rock formations. However, it is not economical to use a survey ship to sample the shallow sediment of rivers and lakes (or reservoirs), and it is easy to disturb the surface sediment when drilling with heavy equipment. In t...
