Abstract

The invention discloses a device for removing rock debris in a hole through waterpower. The device for removing the rock debris in the hole through the waterpower comprises an outer shell, an upper connector, a lower connector, an inlet pipe and an outlet pipe, wherein one end of the upper connector is connected to the upper end of the outer shell, the other end of the upper connector is connected to the lower portion of a driving drill stem, one end of the lower connector is connected to the lower end of the outer shell, the other end of the lower connector is connected with the drill stem, a rock debris containing cavity is formed between the upper connector and the lower connector in the outer shell, the inlet pipe is connected to the bottom of the upper connector in the outer shell through an upper flange plate, the outlet pipe is connected to the upper portion of the lower connector in the outer shell through a lower flange plate, a special-shaped inclined hole is formed in the lower portion of the inlet pipe, spiral pieces used for crushing the rock debris are arranged on the two sides of the portion, corresponding to the position of the special-shaped inclined hole, of the inlet pipe in the outer shell, and water passing holes are formed in the upper portion of the outlet pipe. The device for removing the rock debris in the hole through the waterpower can separate the rock debris from washing liquid in time, abrasion caused on a drill bit by the rock debris is avoided, the service life of the drill bit is prolonged, and drilling efficiency is improved.

Description

technical field [0001] The invention belongs to the technical field of drilling, and in particular relates to a hydraulic debris removal device in a hole. Background technique [0002] The complete rock sample obtained by exploratory drilling in drilling engineering is the most direct technical means to obtain underground information. During the drilling process, the drill bit continuously breaks the rock, and the cuttings at the bottom of the hole are carried to the surface by the flushing fluid. If the cuttings in the flushing fluid are not separated in time and are brought into the hole, the cuttings will be repeatedly broken and wear the drill bit. This will cause the drill bit to do useless work during the drilling process, which will not only affect the drilling efficiency and reduce the life of the drill bit, but also cause in-hole accidents such as burning and sticking in serious cases. Contents of the invention [0003] The object of the present invention is to s...
