Description

Technical Field

[0001] This utility model relates to the field of marine geological exploration equipment technology, specifically to a marine geological drilling tower device. Background Technology

[0002] Marine geological drilling is a core technology for exploring seabed mineral resources, studying marine geological structures, and assessing the carrying capacity of the marine environment. It is widely used in shallow-sea oil and gas exploration, deep-sea mineral development, and early warning of seabed geological disasters. However, current marine geological drilling rigs have poor height adjustment flexibility and insufficient adaptability. Most of them adjust by adding or reducing auxiliary segments, with large adjustment steps, which cannot achieve precise fine-tuning. Utility Model Content

[0003] This utility model proposes a marine geological drilling tower device. Through the cooperation of the cavity of the base, the movable plate and the connecting column, the movable plate can rotate slightly in the cavity to realize the slight attitude adjustment of the drilling tower and counteract the tilting caused by ocean winds and waves.

[0004] Therefore, the technical solution adopted is as follows: A marine geological drilling rig includes a rig body. Several sets of height adjustment mechanisms are uniformly fixed at the bottom of the rig body. A base is fixed at the bottom of each height adjustment mechanism. A cavity is formed inside the base. An opening is formed on the top surface of the base. A movable plate is located inside the cavity. The movable plate is rotatably connected to the center of the bottom surface of the cavity. A connecting column is fixed at the top of the movable plate. The top of the connecting column passes through the opening and extends out of the cavity to connect with the height adjustment mechanism. A fixed plate is fixed at the bottom of the base.

[0005] A further technical solution is that the height adjustment mechanism includes a support block fixed to the tower body and horizontally arranged, a vertically arranged extension column fixed to the bottom of the support block, a sleeve column slidably sleeved on the extension column, a vertically arranged threaded rod in the inner cavity of the sleeve column, a threaded hole matching the threaded rod for insertion on the extension column, the threaded rod can also be rotatably mounted on a retainer fixed to the sleeve column, the threaded rod is connected to a motor through a bevel gear set, and the connecting column is fixed to the sleeve column.

[0006] A further technical solution is that the tower body is a modular splicing structure, which is composed of several tower sections stacked on top of each other and detachably spliced. Each tower section is a polygonal frame structure, and a top frame is fixed to the top of the tower body. An equipment installation platform is fixed on the top frame.

[0007] A further technical solution is that the tower body has several sets of diagonal bracing mechanisms around its perimeter. Each diagonal bracing mechanism includes a diagonal bracing rod. The top end of the diagonal bracing rod is hinged to the tower body via a first hinge, and the bottom end of the diagonal bracing rod is hinged to a vertically arranged support column via a second hinge. A horizontally arranged fixing plate is fixed to the bottom of the support column.

[0008] A further technical solution is that the first fixing plate has a plurality of fixing holes 1, and the second fixing plate has a plurality of fixing holes 2.

[0009] A further technical solution involves fixing several tower sections together with flanges and high-strength bolts, and fixing gaskets between adjacent flanges.

[0010] The working principle and beneficial effects of this application are as follows: 1. Through the cooperation of the cavity of the base, the movable plate and the connecting column, the movable plate can rotate slightly in the cavity to realize the slight attitude adjustment of the drilling tower and counteract the tilt caused by ocean waves. At the same time, through the cooperation of the support block, extension column and sleeve column in the height adjustment mechanism, the height of the drilling tower can be finely adjusted to adapt to more seabed terrain and installation height requirements in actual applications.

[0011] 2. This marine geological drilling rig features a multi-section detachable tower design, enabling rapid assembly and disassembly of the rig. It adapts to marine transportation and on-site construction needs. The equipment installation platform on the top frame allows for centralized installation of drilling equipment, optimizing equipment layout. Meanwhile, the surrounding diagonal bracing mechanism enhances the tower's resistance to lateral displacement. Attached Figure Description

[0015] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this utility model.

[0016] like Figures 1-5 As shown, a marine geological drilling rig includes a rig body 1. Several sets of height adjustment mechanisms 11 are uniformly fixed at the bottom of the rig body 1. A base 7 is fixed at the bottom of each height adjustment mechanism 11. A cavity 702 is opened inside the base 7. An opening 701 is opened on the top surface of the base 7. A movable disk 9 is located inside the cavity 702. The movable disk 9 is rotatably connected to the center of the bottom surface of the cavity 702. A connecting column 8 is fixed at the top of the movable disk 9. The top of the connecting column 8 passes through the opening 701, protrudes from the cavity 702, and is connected to the height adjustment mechanism 11. A fixed disk 10 is fixed at the bottom of the base 7.

[0017] In this embodiment, the cavity 702 of the base 7, the movable disk 9, and the connecting column 8 cooperate to achieve slight attitude adjustment of the drilling rig, counteracting the tilting caused by ocean waves. The movable disk 9 is omnidirectionally rotatable at the center of the bottom surface of the cavity 702. When the rig 1 tilts slightly due to ocean waves, it tilts and rotates with the rig 1. However, due to the function of the cavity 702 and the connecting column 8, the direction of rotation is unlimited, but the range of rotation is limited. Therefore, it can accommodate slight swaying of the rig 1, preventing excessive rigidity of the rig 1 from causing greater damage, while also preventing the tilt angle of the rig 1 from becoming too large. In the setup, the diameter of the movable disk 9 is slightly smaller than the diameter of the cavity 702, and the diameter of the connecting column 8 is slightly smaller than the diameter of the opening 701. The specific diameter range can be adjusted according to actual needs, providing slight attitude adjustment space for the drilling rig. The fixed disk 10 is fixed to the hull or seabed base to ensure the stability of the base 7.

[0018] Among them, such as Figure 2and Figure 5 As shown, one embodiment of the height adjustment mechanism 11 includes a support block 4 fixed to the tower body 1 and horizontally arranged. A vertically arranged extension column 5 is fixed to the bottom of the support block 4. A sleeve column 6 is slidably sleeved on the extension column 5. The inner cavity of the sleeve column 6 has a vertically arranged threaded rod 1101. A threaded hole 501 matching the threaded rod 1101 is opened on the extension column 5 for insertion. The threaded rod 1101 can also be rotatably mounted on a retainer 1102 fixed to the sleeve column 6. The threaded rod 1101 is connected to a motor 1103 through a bevel gear set 1104. The connecting column 8 is fixed to the sleeve column 6.

[0019] By cooperating with the support block 4, extension column 5, and sleeve column 6, the height of the drilling tower can be finely adjusted to adapt to different seabed terrains. The threaded rod 1101 engages with the threaded hole 501 of the extension column 5, converting the rotational motion into the linear lifting and lowering of the extension column 5. The retainer 1102 fixes the threaded rod 1101 to ensure stable rotation. Through the transmission of the motor 1103 and the bevel gear set 1104, the height can be automatically adjusted. Specifically, the motor drives the bevel gear set 1104 to drive the threaded rod 1101 to rotate, thereby realizing the up and down movement of the extension column 5, thus achieving fine-tuning of the height of the tower body 1. Compared to the fixed and relatively high height of each module of the tower body, fine-tuning the height can better adapt to the actual height requirements.

[0020] like Figure 1 As shown, one embodiment of the tower body 1 is a modular splicing structure, composed of several tower sections stacked vertically and detachably. Each tower section is a polygonal frame structure. A top frame 2 is fixed to the top of the tower body 1, and an equipment installation platform 201 is fixed on the top frame 2. The detachable connection design of the tower body 1 enables rapid assembly and disassembly of the drilling tower, adapting to marine transportation and on-site construction needs. The top frame 2 and equipment installation platform 201 allow for centralized installation of drilling equipment, optimizing equipment layout. Guide rails are provided on the inner side of the tower body 1 for sliding guidance of the drilling equipment, ensuring a smooth drilling process and improving drilling efficiency. Several tower sections are fixed by flanges and high-strength bolts, and sealing gaskets are fixed between adjacent flanges to achieve sealing and protection of the tower body.

[0021] In another embodiment of the tower body 1, several sets of diagonal bracing mechanisms 3 are provided around its perimeter. Each diagonal bracing mechanism 3 includes a diagonal brace 302. The top end of the diagonal brace 302 is hinged to the tower body 1 via a first hinge 301, and the bottom end of the diagonal brace 302 is hinged to a vertically arranged support column 304 via a second hinge 303. A horizontally arranged fixing plate 305 is fixed to the bottom of the support column 304. The diagonal bracing mechanism 3 enhances the tower body's resistance to lateral displacement. The diagonal brace 302 is connected to the tower body 1 via the first hinge 301, allowing for flexible adjustment of the angle of the diagonal brace 302. The diagonal brace 302 cooperates with the support column 304 via the second hinge 303 and is fixed to the mounting surface by the fixing plate 305, forming a stable triangular structure.

[0022] Based on this, a number of fixing holes 1001 are provided on the fixing plate 10, and a number of fixing holes 306 are provided on the fixing plate 305. Fixing holes 1001 and 306 are used to insert bolts, etc., to achieve a firm connection between the base 7 and the hull or seabed base, to distribute the overall weight and operating load of the drilling rig, to prevent displacement of the base 7, to ensure multi-point fixation of the support column 304 to the mounting surface, to distribute fixing stress, and to avoid fixing failure caused by excessive force at a single point.

[0023] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
