DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the invention to clearly and completely describe the technical solutions in the embodiments of the invention. Obviously, the described embodiments are only part of the embodiments of the invention, not all of the embodiments. Unless otherwise specified, the technical means used in the embodiments are conventional means well known to those skilled in the art.

[0024] In the description of the invention, it is necessary to understand that the terms "longitudinal", "lateral", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside" and "outside" etc. indicating orientations or positional relationships are based on the orientations or positional relationships shown in the accompanying drawings and are only for the convenience of describing the invention, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the invention.

[0025] See also Figure 1 and Figure 2 The embodiment of the present application provides a deep-water floating platform complex formation drilling equipment, including a platform 1 and a pontoon 2 arranged on the platform 1, and also including a driving component 3 arranged on the pontoon 2, the driving component 3 including a driving chamber 31 and a closing portion 34. The driving chamber 31 includes a cylindrical side wall, and a plurality of discharge channels 32 are arranged at intervals on the side wall around the circumference of the side wall. A plurality of closing portions 34 are connected to the driving chamber 31 in a rotational manner around the axis of the side wall, and the closing portion 34 abuts against the outer peripheral surface of the side wall to close the discharge channel 32.

[0026] The platform 1 is used to install other components of the drilling equipment, such as lifting components and drilling components.

[0027] The buoyancy tank 2 enables the platform 1 to float on the water surface.

[0028] The discharge channel 32 of the driving chamber 31 is used to discharge the medium to generate a thrust for driving the buoyancy chamber 2 to move. The discharged medium may be liquid or gas.

[0029] The closing portion 34 is used to close the discharge channel 32 to adjust the thrust direction generated by the drive chamber 31 on the pontoon 2. For example, when the closing portion 34 is located on the left side, the discharge channel 32 on the left side is blocked, and the discharge channel 32 on the right side can still continue to discharge the medium, so that the drive chamber 31 can generate a leftward thrust on the pontoon 2. In addition, since there are multiple closing portions 34, the position of each closing portion 34 can be reasonably set, so that the thrust direction generated by the drive chamber 31 on the pontoon 2 is more diverse and the adjustment range is wider. Compared with the traditional method of realizing dynamic positioning by a thruster, the embodiment of the present application generates thrust through the cooperation of the drive chamber 31 and the closing portion 34, which is convenient for adjusting the thrust direction on the pontoon 2, and thus has a better positioning effect on the drilling equipment.

[0030] See also Figure 1 In some embodiments, the driving chamber 31 can be rotatably connected to the buoyancy box 2, and a paddle 4 can be provided on the outside of the driving chamber 31. The paddle 4 can be provided at the bottom of the driving chamber 31, so that when the driving chamber 31 generates insufficient thrust, the driving chamber 31 can be rotated and the paddle 4 can be used to generate thrust.

[0031] See also Figure 1 In some embodiments, a plurality of rotating shafts 35 are provided on the driving chamber 31 corresponding to the number of the closing portions 34. The rotation center of the rotating shaft 35 extends along the axis of the side wall of the driving chamber 31. The plurality of closing portions 34 are connected to the rotating shaft 35 one by one. When the rotating shaft 35 rotates, the closing portions 34 can rotate therewith, thereby achieving the purpose of adjusting the position of the closing portions 34.

[0032] In the embodiment of the present application, the driving component 3 can be set to one or more as needed.

[0033] See also Figure 2 In some embodiments, baffles are arranged at intervals on the outer circumference of the side wall along the axial direction of the side wall, the baffles are arranged around the outer circumference of the side wall, and the sealing portion 34 is arranged between two adjacent baffles.

[0034] The baffle is used to limit the movement of the closing portion 34 .

[0035] The baffle plate cooperates with the closing portion 34 to improve the movement accuracy of the closing portion 34 .

[0036] In some embodiments, the driving cavity 31 is further provided with a plurality of entry channels 33 .

[0037] The inlet channel 33 can be used to allow external media to pass into the drive chamber 31 .

[0038] A plurality of inlet channels 33 may be disposed around the axis of the side wall of the driving cavity 31 .

[0039] See also Figure 3For example, a spiral blade 36 may be provided in the driving chamber 31 , and the spiral blade 36 rotates so that the external medium can be sucked into the driving chamber 31 from the inlet channel 33 .

[0040] See also Figure 4 In some embodiments, the inner wall of the entry channel 33 is provided with a plurality of spikes 38 , and the spikes 38 partially extend through the entrance of the entry channel 33 to the outside of the entry channel 33 .

[0041] The spike 38 is used to reduce the risk of foreign matter being sucked into the driving cavity 31 through the inlet channel 33 , and the spike 38 is small in size and does not form an obstacle to the medium.

[0042] See also Figure 4 In some embodiments, the inner wall surface of the entrance channel 33 is provided with a spiral groove 37 whose spiral axis extends along the axis of the entrance channel 33 .

[0043] The spiral groove 37 allows the medium entering the channel 33 to rotate. On the one hand, it is convenient for the external medium to enter the driving cavity 31. On the other hand, when the external medium rotates, it is convenient to throw away or tear up the foreign impurities inserted on the spikes 38, thereby reducing the risk of impurities blocking the channel 33.

[0044] In some embodiments, the spiral groove 37 is provided in plurality, and the plurality of spiral grooves 37 have the same rotation direction.

[0045] By providing a plurality of spiral grooves 37 , the rotation effect of the external medium entering the channel 33 is improved.

[0046] See also Figure 5 In some embodiments, a winding component 5 is further included, and the winding component 5 includes a driving wheel, a limiting cylinder 58 and a shock-absorbing assembly. The driving wheel is rotatably connected to the platform 1 for moving the anchor chain 6. The limiting cylinder 58 is arranged on the platform 1 for guiding the anchor chain 6. Two shock-absorbing assemblies are provided, and the two shock-absorbing assemblies are relatively arranged on the limiting cylinder 58. The shock-absorbing assembly includes a support portion 59 and two shock-absorbing wheels 54. The support portion 59 is rotatably connected to the limiting cylinder 58. The two shock-absorbing wheels 54 are rotatably arranged on the support portion 59. One of the two shock-absorbing wheels 54 is arranged in the limiting cylinder 58, and the other is arranged outside the limiting cylinder 58.

[0047] The anchor chain 6 is used to anchor the drilling equipment. For example, one end of the anchor chain 6 may be provided with an anchor, which is put into the water and hooked on the stratum to fix the drilling equipment.

[0048] The anchor chain 6 is wound around the outer circumference of the driving wheel. When the driving wheel rotates, a pulling force can be generated on the anchor chain 6, which is convenient for winding or unwinding the anchor chain 6.

[0049] The anchor chain 6 is inserted into the limiting tube 58 , so that the limiting tube 58 can limit the anchor chain 6 .

[0050] The support portion 59 is used to reduce the axial vibration of the anchor chain 6 during movement, which not only reduces the noise of the anchor chain 6 during winding and unwinding, but also increases the service life of the anchor chain 6. For example, the portion of the anchor chain 6 that has not entered the limiting cylinder 58 is pressed on the damping wheel 54 located outside the limiting cylinder 58, so that the two damping wheels 54 of the two damping assemblies located in the limiting cylinder 58 can move closer to each other, clamping the anchor chain 6, reducing the axial vibration of the anchor chain 6, and further reducing the noise generated when the anchor chain 6 is wound and unwound. At the same time, the damping wheel 54 and the anchor chain 6 are in rolling friction fit, which is less wear than the direct contact between the anchor chain 6 and the inner wall of the limiting cylinder 58, thereby increasing the service life of the anchor chain 6.

[0051] In the embodiment of the present application, a torsion spring may be provided between the support portion 59 and the limiting cylinder 58 to generate an elastic force for returning the support portion 59 to its original position.

[0052] See also Figure 5 In some embodiments, the driving wheel includes a supporting wheel 51, a plurality of connections and a supporting rod. The supporting wheel 51 is rotatably connected to the platform 1. A plurality of chain links 55 are detachably connected in sequence to form an annular structure, and two adjacent chain links 55 are rotatably connected, and the annular structure is sleeved outside the supporting wheel 51. The supporting rod is connected to the supporting wheel 51 to support the annular structure, and the supporting rod is configured to be adjustable in length.

[0053] The ring structure formed by the plurality of chain links 55 is used to contact the anchor chain 6 to drive the anchor chain 6 to move. To increase the friction between the chain link 55 and the anchor chain 6 , a protrusion 56 may be provided on one side of the chain link 55 facing the anchor chain 6 .

[0054] Two adjacent links 55 may be connected by a latch, so that the two links 55 are detachably connected and can rotate relative to each other.

[0055] The adjustable length of the support rod means that the length of the support rod along the radial direction of the support wheel 51 can be adjusted as needed.

[0056] Since the multiple links 55 are detachably connected, the radius of the ring structure formed by the multiple links 55 can be adjusted as needed. The larger the radius, the faster the anchor chain 6 moves, and the smaller the radius, the slower the anchor chain 6 moves.

[0057] Furthermore, by adjusting the radius of the annular structure, the friction force on the anchor chain 6 can be reduced. For example, by adjusting the radius of the annular structure, the angle between the portion of the anchor chain 6 outside the limiting cylinder 58 and the horizontal plane can be changed. When the angle becomes larger, the clamping of the anchor chain 6 by the two shock-absorbing wheels 54 located in the limiting cylinder 58 is reduced, so that the movement of the anchor chain 6 is smoother.

[0058] See also Figure 5 In some embodiments, the support rod includes a threaded sleeve 53 and two rod bodies 52, one of the two rod bodies 52 is connected to the support wheel 51, and the other of the two rod bodies 52 is against the inner wall surface of the annular structure, and the two rod bodies 52 are threadedly matched with the threaded sleeve 53.

[0059] The axial direction of the threaded sleeve 53 may extend along the radial direction of the supporting wheel 51 .

[0060] One end of the two rod bodies 52 can be inserted into the threaded sleeve 53 and threadably matched with the threaded sleeve 53 .

[0061] By rotating the threaded sleeve 53, the radial distance between the two rod bodies 52 in the support wheel 51 can be adjusted to achieve the purpose of adjusting the length of the support rod.

[0062] In some embodiments, the support wheel 51 is provided with a plurality of threaded holes 57 around the circumference of the support wheel 51 , and the rod body 52 is selectively threadedly connected to the threaded holes 57 .

[0063] By providing a plurality of threaded holes 57 on the support wheel 51 , the number of support rods and the angles of the support rods can be adjusted as needed to adjust the supporting effect on the annular structure.

[0064] The above embodiments are only descriptions of the preferred modes of the invention, and are not intended to limit the scope of the invention. Without departing from the spirit of the invention, various deformations, modifications, alterations, and substitutions made to the technical solutions of the invention by ordinary technicians in this field should all fall within the scope of protection determined by the claims of the invention.
