Description

Technical Field

[0001] The utility model relates to the technical field of marine engineering construction, in particular to a drilling device for marine engineering construction. Background Art

[0002] Marine engineering refers to new construction, reconstruction, and expansion projects that aim to develop, utilize, protect, and restore marine resources, with the main body of the project located on the seaward side of the coastline. During the construction of marine engineering, drilling equipment is required to drill holes into the seabed.

[0003] Drilling equipment used in marine engineering construction primarily consists of the drill bit, drill pipe, drilling control system, and lifting system. Its operating principle is to complete seabed drilling operations by rotating the drill pipe, causing the drill bit to rotate and cut through the underwater soil. Hydraulic or electric systems are typically used to raise and lower the drilling equipment. Generally speaking, marine engineering drilling equipment achieves seabed drilling operations by rotating the drill bit through the underwater soil. Its simple structure, easy operation, and high efficiency make it suitable for marine engineering operations such as soil layer detection, sample collection, and foundation drilling.

[0004] When drilling holes on the seabed, existing drilling equipment usually uses a mud pump to extract the mud and sand generated during drilling. Due to the effect of seabed water pressure, a large amount of seawater will flow back into the pipe mouth, resulting in a lower efficiency of the initial mud and sand extraction when the mud pump is working, resulting in a greater chance of drilling obstruction. Therefore, to address the above problems, a drilling equipment for marine engineering construction is proposed. Utility Model Content

The mud pump is covered on the drill hole through the mud pumping cover, and the baffle moves into the slide groove, and the pipe mouth of the guide pipe is opened; then the mud pump pumps the mud and sand generated by the drill hole into the mud pumping cover and discharges it from the discharge pipe, thereby realizing the extraction and discharge of mud and sand. This structure avoids a large amount of seawater from flowing back into the pipe mouth by setting the baffle, which is beneficial to improving the efficiency of the mud pump in initially extracting mud and sand.

[0008] The utility model is beneficial in that:

[0009] 1. The utility model covers the drill hole with a mud pumping cover, moves the baffle into the chute, and opens the pipe opening of the material guide pipe. Then, the mud pump pumps the mud and sand generated by the drill hole into the mud pumping cover and discharges it from the discharge pipe, thus realizing the extraction and discharge of mud and sand.
