Description

Technical Field

[0001] This utility model relates to the field of marine geological exploration technology, and in particular to an integrated drilling and static exploration device. Background Technology

[0002] Currently, marine geological exploration commonly employs seabed-based equipment or large shipborne equipment (such as drilling rigs). Shipborne large equipment places high demands on the vessel, incurs high costs, has long operation cycles, and is inconvenient to operate. Seabed-based equipment, using hydrostatic penetration sensors or drilling equipment, also has its limitations and lacks comprehensive functionality. Shallow-water hydrostatic penetration equipment can conduct exploration at considerable depths, but requires the installation of probes from the vessel, making it unsuitable for deep-sea areas. Deep-sea hydrostatic penetration equipment accommodates fewer probes, limiting its ability to conduct deep-sea exploration. Seabed drilling equipment can perform drilling operations at considerable depths, but it is not compatible with hydrostatic exploration and has a relatively limited functionality. Utility Model Content

[0007] In some embodiments, the number of chains is two, and the two chains are spaced apart in the vertical direction.

[0008] In some embodiments, the clamping assembly includes a clamping member, a first driving member, and a second driving member. The clamping member is connected to the first driving member, which drives the clamping member to clamp the rod, and the second driving member drives the clamping member to reciprocate within the drive assembly and the sprocket assembly.

[0009] In some embodiments, the clamping member includes a first clamping jaw, a second clamping jaw, a first connecting rod, and a second connecting rod.

[0041] Preferred embodiments of the present application will now be described in more detail with reference to the accompanying drawings. While preferred embodiments of the present application are shown in the drawings, it should be understood that the present application may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided to make the present application more thorough and complete, and to fully convey the scope of the present application to those skilled in the art.

[0042] In the description of the application, it should be understood that the terms "one end", "the other end", "outer side", "upper", "inner side", "horizontal", "coaxial", "center", "end", "length", "outer end", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0043] Furthermore, in the description of this application, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0044] To address the issue that existing drilling and static pressure testing methods can only be performed independently, this invention provides an integrated drilling and static pressure testing device that combines drilling and static pressure testing. It is capable of automatic assembly and operation, and features high efficiency and ease of operation, thus meeting the needs of multi-functional operations.

[0045] The technical solutions of the embodiments of this application are described in detail below with reference to the accompanying drawings.

[0046] like Figures 1 to 2 As shown, the present invention provides an integrated drilling and static exploration device, including a platform 1. The platform 1 is provided with a sprocket assembly 2, a clamping assembly 3, and a drive assembly 4. The sprocket assembly 2 includes a drive sprocket 21 and a chain 22 meshing with the drive sprocket 21. The chain 22 has multiple limiting structures 220 for installing rods 5. The clamping assembly 3 is used to reciprocate to pick up and transport the rods 5 between the limiting structures 220 and the drive assembly 4. The drive assembly 4 is used to perform penetration and retrieval operations on the rods 5. The rods 5 include drill rods and probe rods 51.

[0047] Specifically, platform 1 is a rectangular frame. The central part of platform 1 is used to house the drive assembly 4, which provides power to the drill pipe and probe 51 to enable the penetration and retrieval of the drill pipe / probe 51. The sprocket assembly 2 is used to house the probe 51 or drill pipe. The drive sprocket 21 drives the chain 22 to circulate. The chain 22 is located on the outside of the drive assembly 4, and the limiting structure 220 is correspondingly located on the outside of the chain 22. The limiting structure 220 is used to house the drill pipe or probe 51. In practical implementation, since the drill rod and probe rod 51 have different size specifications, the chain 22 can be set with two types of limiting structures 220 that are compatible with the drill rod or probe rod 51. Alternatively, the drilling and static pressure operations can be switched by replacing the chain 22. Driven by the drive sprocket 21, the rod 5 moves cyclically with the chain 22. Automatic connection is achieved through the clamping assembly 3, and the insertion and retrieval operations of the rod 5 are achieved through the drive assembly 4. This realizes automated operation and has the characteristics of high efficiency and easy operation.

[0048] In a preferred embodiment, the chain 22 includes a plurality of drive links 221 and a plurality of clamping links 222. The drive links 221 and clamping links 222 are alternately hinged, and the drive links 221 are engaged with the drive sprocket 21. The clamping links 222 are provided with the limiting structure 220. The chain 22 is composed of drive links 221 and clamping links 222, which are alternately hinged to form the chain 22. The probe rod 51 and the drill rod are clamped and stored through the clamping links 222. When it is necessary to switch between drilling and hydrostatic pressure operations, the entire chain 22 can be removed and replaced with a chain 22 of the corresponding clamping diameter. In addition, if drilling and hydrostatic pressure operations need to be carried out in a single operation, different clamping links 222 can be installed on the chain 22 to ensure that the drill rod and the probe rod 51 can be clamped and stored.

[0049] Based on the above specific embodiments, in order to increase the number of rods 5 that the platform 1 can accommodate, the platform 1 is also provided with a guide groove (not shown) that is connected end to end. The guide groove is recessed inward to form a notch for avoiding the drive assembly 4. The chain 22 slides in cooperation with the guide groove to guide the cyclic movement of the chain 22. By setting the guide groove, the distribution of the chain 22 can surround the periphery of the platform 1, thereby constructing a U-shaped cyclic transmission chain 22 on the platform 1. By engaging the chain 22 with the guide groove, the chain 22 can be guided to transmit power in a preset direction. With this setting, the total length of the chain 22 can be increased, thereby increasing the number of rods 5 that the chain 22 can accommodate.

[0050] Furthermore, there are two chains 22, which are spaced apart vertically. Each chain 22 has multiple limiting structures 220, which are evenly spaced along the length of the chain 22 on its outer surface. Both chains 22 have limiting structures 220. In some embodiments, the limiting structures 220 are slots for the drill rod or probe rod 51 to be inserted. Friction pads can also be placed in the slots to increase the friction on the rod 5. The limiting structures 220 of the two chains 22 correspond one-to-one, thus ensuring that the multiple rods 5 installed on the chains 22 are parallel to each other.

[0051] In a preferred embodiment, the clamping assembly 3 includes a clamping member 31, a first driving member 32, and a second driving member. The clamping member 31 is connected to the first driving member 32. The first driving member 32 is used to drive the clamping member 31 to clamp the rod 5. The second driving member is used to drive the clamping member 31 to reciprocate in the drive assembly 4 and the sprocket assembly 2.

[0052] Based on the above specific embodiments, the clamping member 31 includes a first clamping claw 311, a second clamping claw 312, a first connecting rod 313 and a second connecting rod 314. The middle part of the first clamping claw 311 is hinged to the middle part of the second clamping claw 312. The first end of the first clamping claw 311 is provided with a first groove, and the first end of the second clamping claw 312 is provided with a second groove. The first groove and the second groove are arranged opposite to each other. The first groove can cooperate with the second groove to form a clamping groove for the rod 5 to be inserted.

[0053] The first end of the first connecting rod 313 is hinged to the first end of the second connecting rod 314, the second end of the first connecting rod 313 is hinged to the second end of the first gripper 311, and the second end of the second connecting rod 314 is hinged to the second end of the second gripper 312.

[0054] The output end of the first driving member 32 is hinged to the first end of the first connecting rod 313. The action of the output end of the first driving member 32 can drive the first groove and the second groove to move closer or further apart.

[0055] Furthermore, the first driving component 32 is a first hydraulic cylinder, and the second driving component is a rotary motor.

[0056] In a preferred embodiment, the drive assembly 4 includes a power head 41, a drive connector 42, a guide rail 43, and a shackle assembly 44;

[0057] The power head 41 is slidably engaged with the guide rail 43. The power head 41 is used to drive the drive joint 42 to rise and fall and to drive the drive joint 42 to rotate around its own axis.

[0058] The drive connector 42 includes an inner connector 421 and an outer connector 422 that are interconnected. The inner connector 421 has a mounting cavity that is adapted to the probe rod 51, and the outer connector 422 has a mounting cavity that is adapted to the drill rod.

[0059] The shackle assembly 44 is used to connect or disconnect two rods 5.

[0060] Specifically, the power head 41 is the power mechanism for driving drilling and hydrostatic operations. The power head 41 can move up and down along the guide rail 43 to perform the insertion and extraction operations of the probe rod 51 and the drill rod. The power head 41 can also drive the drive structure to rotate to perform operations such as mounting, unmounting, and drilling of the probe rod 51 and the drill rod. The drive joint 42 is divided into inner and outer layers, which can simultaneously accommodate the drill rod and the probe rod 51. The inner joint 421 is used to install the probe rod 51, and the outer joint 422 is used to install the drill rod. The unmounting assembly 44 is located at the bottom of the drive assembly 4. The upper unmounting assembly 44 can rotate around the central axis of the drive joint 42, and the lower unmounting assembly 44 can rotate counterclockwise relative to the upper unmounting assembly 44. With this configuration, the drill rod and the probe rod 51 can be threadedly connected, thereby connecting or disconnecting the two rods 5.

[0061] Based on the above specific embodiments, the shackle assembly 44 includes two shackle parts arranged vertically on the guide rail 43. Each shackle part includes a rotating seat 441 and two second hydraulic cylinders 442 symmetrically arranged on the rotating seat 441. The output ends of the second hydraulic cylinders 442 are in the same radial direction as the mounting cavity, and the output ends of the two second hydraulic cylinders 442 are opposite to each other.

[0062] The rotating seat 441 closer to the drive joint 42 rotates clockwise around the axis of the drive joint 42, while the rotating seat 441 further away from the drive joint 42 rotates counterclockwise around the axis of the drive joint 42, so as to connect or disconnect the two rods 5.

[0063] In a preferred embodiment, the probe 51 is a solid structure. The first end of the probe 51 is provided with a threaded cavity, and the bottom wall of the threaded cavity is provided with a first electrode ring 511. The second end of the probe 51 is provided with a conical boss that matches the threaded cavity. The end face of the conical boss is provided with a second electrode ring that mates with the first electrode ring 511. Two adjacent probes 51 are threaded together. The probe 51 contains a cable that connects the first electrode ring 511 and the second electrode ring.

[0064] The drive connector 42 is provided with a third electrode ring and an electric slip ring. The third electrode ring is electrically connected to the probe rod 51, the third electrode ring is connected to the electric slip ring, and the electric slip ring is connected to the data acquisition device.

[0065] Existing probe rods 51 are generally hollow structures with internal cables for data transmission, but this results in cumbersome installation. To solve this problem, the probe rod 51 provided in this invention is a solid structure. Multiple electrode rings are located on both ends of the probe rod 51, with each end corresponding to the previous one. A cable passes through the center of the probe rod 51 for connection, ultimately connecting the bottom probe and the top inner drive connector 42. The drive connector 42 also has the same electrode ring structure, which connects to a built-in slip ring, enabling circuit connection during rotation. The slip ring then connects to the data acquisition device and other electrical control modules in the equipment, achieving connection with the probe and enabling cable-free data acquisition.

[0066] Compared with the prior art, the integrated drilling and static exploration device provided by this utility model has the following advantages:

[0067] 1. The equipment has a high degree of integration and can adapt to various operational needs;

[0068] 2. The pipe rack structure is easy to disassemble and maintain, and can easily switch between drilling, probe rod 51 and casing clamps, quickly adapting to various operational needs;

[0069] 3. Compared with general seabed equipment, it can accommodate a large number of hydrostatic probes 51, achieving a deeper penetration depth.

[0070] 4. It can be combined with drilling and static pressure operations to achieve the effect of casing, providing protection and better penetration results;

[0071] 5. It can automatically assemble and disassemble probe rods and drill rods, which is efficient and easy to operate.
