Description

Technical Field

[0001] This invention belongs to the field of marine exploration technology, specifically a drilling rig and method for exploring seabed rocks and polymetallic sulfides that prevents tilting. Background Technology

[0002] Seafloor polymetallic sulfides are rich in copper, lead, zinc, gold, silver, and other metallic elements, with global reserves reaching 400 million tons, making them a highly promising marine mineral resource. The "Regulations for the Exploration and Development of Resources in the International Seafloor Areas," led by the International Seafloor Authority, are about to be promulgated. Countries worldwide are making final technical preparations for exploration and development, creating a pressing international situation. Unlike polymetallic nodules and cobalt-rich crusts that are attached to the seabed or rock surfaces, polymetallic sulfide deposits are more three-dimensional. Traditional seafloor photography, video recording, or magnetic surveying methods cannot accurately assess the reserves of polymetallic sulfide deposits. Accurate calculation of polymetallic sulfide reserves requires the use of exploration drilling rigs, but existing rigs are less practical for the complex terrain of polymetallic sulfide mining areas. In the prior art, Chinese Patent CN215108732U discloses a portable geological exploration drilling rig with controllable tilt angle, published on December 10, 2021. It achieves angle adjustment of the drilling rig body by adjusting the adjusting screws on both the front and rear sides, indirectly limiting the rotation angle of the two connecting rods. The foot pads are in contact with the ground. However, in some complex terrains with uneven ground, some foot pads may not be in contact with the ground, making the exploration drilling rig prone to swaying, slipping, or even tipping over, thus affecting exploration. Chinese Patent CN111287671A discloses a subsea drilling rig site-finding and landing device and its usage method. It activates the site-finding device when the drilling rig is lowered to 10 meters above the seabed surface, and only opens the mechanical legs when a ground elevation difference of no more than 0.1 meters is found. However, it does not solve the problem of maintaining the stability of the exploration drilling rig in complex terrain. Summary of the Invention

[0003] In view of the above situation and to overcome the defects of the prior art, the present invention provides an anti-tilting seabed rock and polymetallic sulfide exploration drilling rig and method, which effectively solves the problems in the background art.

[0004] To achieve the above objectives, the present invention provides the following technical solution: an anti-tilting seabed rock and polymetallic sulfide exploration drilling rig, comprising an equipment housing, a swing seat provided inside the equipment housing, a first through hole opened in the bottom inner wall of the equipment housing, a movable seat provided at the bottom of the swing seat, a drilling rig body provided at the bottom of the movable seat, the movable seat and the swing seat connected by a spacing control mechanism, the swing seat and the equipment housing connected by a multi-directional rotator, four first lead screws provided inside the equipment housing, the top end of the first lead screws penetrating the top inner wall of the equipment housing, a threaded sleeve fitted on the outside of the first lead screws, the bottom of the threaded sleeve being fixedly connected to the top of the equipment housing, a synchronous plugging assembly cooperating with the four first lead screws provided on the equipment housing, and an anti-tilting adjustment assembly provided on the equipment housing;

[0005] The anti-tilt adjustment assembly includes four sliding seats, each located on one of the four sides of the equipment housing. Support plates are fixedly connected to each of the four sides of the equipment housing. Rollers are located at the bottom of each sliding seat. A first rectangular hole is formed in each sliding seat, through which the support plate passes. A movable ring is fitted around the outside of the equipment housing, connected to the housing via a lifter. The sliding seat and support plate are connected via a lifting snap-fit ​​mechanism. A second rectangular hole is formed in each sliding seat. First movable plates are located on each of the four sides of the equipment housing, passing through the second rectangular hole. Two grooves are formed on the first movable plate. Two sliders are fixedly connected to the inner wall of the second rectangular hole, with adjacent sliders located within the two grooves. A rotatably connected gear is located above the sliding seat. A first toothed plate is fixedly connected to one side of the first movable plate. A second toothed plate is located above the gear. The second toothed plate and the movable ring are connected via a telescopic frame. The second toothed plate and the sliding seat are slidably connected via a sliding component. When the ground is uneven, an external lifting device drives the equipment housing upwards, preventing the rollers from tilting. Then, upon contact with the ground, the position of the sliding seat is manually adjusted, thereby changing the position of the first movable plate. Through the design of the telescopic frame, the second toothed plate moves horizontally relative to the movable ring. Through the design of the sliding component, the second toothed plate slides vertically relative to the sliding seat. When the sliding seat moves, the second toothed plate moves with it, changing the distance between the second toothed plate and the movable ring. The first movable plate is then manually driven to move vertically relative to the sliding seat, changing its height. This ensures that the bottoms of all four first movable plates are in contact with the ground. When the first movable plate moves, the first toothed plate drives the gear to rotate, which in turn drives the movable ring downwards via the lifting device. This causes the telescopic frame to drive the second toothed plate downwards, thus engaging the gear and preventing gear rotation. This prevents the first toothed plate from moving vertically, thus fixing the first movable plate relative to the sliding seat. This completes the fixation of the height of the four first movable plates, ensuring that the bottoms of all four first movable plates are in contact with the ground, and supporting the equipment housing through the four first movable plates.

[0006] Preferably, the lifting snap-fit ​​mechanism includes a second movable plate disposed above the sliding seat. The sliding seat has two insertion holes, and the support plate has several slots. The second movable plate and the sliding seat are connected by several first tension springs. Two insert plates are fixedly connected to the bottom of the second movable plate. The insert plates pass through the insertion holes, and the bottom end of the insert plates is inserted into one of the corresponding slots. The second movable plate is provided with a lifting sliding unit that cooperates with the movable ring.

[0007] Preferably, the lifting and sliding unit includes a first fixed plate disposed on the top of the second movable plate, the first fixed plate and the second movable plate are fixedly connected, a second fixed plate is provided on one side of the second movable plate, the second fixed plate and the first fixed plate are connected by a first connecting plate, a support plate is provided between the second movable plate and the first connecting plate, a plurality of rotating rollers are provided on the top of the support plate, and the two ends of the rotating rollers are rotatably connected to the first fixed plate and the second fixed plate respectively, and the support plate and the movable ring are connected by a tension member.

[0008] Preferably, the tensioning member includes a third fixing plate disposed on one side of the support plate, one side of the third fixing plate is fixedly connected to the movable ring, a positioning plate is fixedly connected to one side of the support plate, and the positioning plate passes through the third fixing plate, and the support plate and the third fixing plate are connected by a compression spring.

[0009] Preferably, the lifting device includes several hydraulic telescopic rods disposed at the bottom of the equipment housing. The top end of the hydraulic telescopic rod is fixedly connected to the bottom of the equipment housing, and the bottom end of the hydraulic telescopic rod is connected to the movable ring through a support frame. The support frame is moved by driving the hydraulic telescopic rod, thereby adjusting the height of the movable ring.

[0010] Preferably, the spacing control mechanism includes two motors mounted on the swing seat. The output end of each motor is provided with a second lead screw, which passes through the swing seat and the movable seat. The second lead screw and the movable seat are connected by a threaded connection. A second connecting plate is provided below the movable seat. The second lead screw and the second connecting plate are connected by a bearing, and the drilling rig body passes through the second connecting plate. The second lead screw is driven to rotate by the motor, which in turn drives the movable seat to move, thereby adjusting the distance between the movable seat and the swing seat. This allows the drilling rig body to move relative to the swing seat and perform drilling through the drilling rig body.

[0011] Preferably, the multi-directional rotator includes a fixed block disposed on the top of the swing seat, the fixed block and the swing seat are fixedly connected, a spherical groove is provided on the fixed block, a connecting column is fixedly connected to the top inner wall of the equipment box, a fixed ball is fixedly connected to the bottom end of the connecting column, and the fixed ball is located in the spherical groove. Through the design of the fixed block, the spherical groove, the fixed ball and the connecting column, the swing seat can be rotated and connected to the equipment box in multiple directions.

[0012] Preferably, the synchronous plug-in assembly includes a first fixed plate disposed at the top of the first lead screw, the first fixed plate and the first lead screw being fixedly connected, the first fixed plate having a plurality of second through holes, a plug rod disposed above the first fixed plate, the plug rod passing through one of the corresponding second through holes, a second fixed plate disposed above the equipment housing, and the plug rod and the second fixed plate being connected by a third connecting plate.

[0013] Preferably, the bottom of the second fixed plate is provided with a prism, the bottom of which is fixedly connected to the top of the equipment housing. A slot is provided at the top of the prism, and a locking block is fixedly connected to the bottom of the second fixed plate, inserting into the slot. A baffle is provided at the top of the second fixed plate, a third movable plate is fixedly connected to one side of the baffle, and two fixed posts are fixedly connected to one side of the prism, penetrating the third movable plate. A second tension spring is sleeved on the outside of the fixed posts, with both ends fixedly connected to the prism and the third movable plate, respectively. Four positioning sleeves are fixedly connected to the top of the equipment housing, and the bottom ends of four insertion rods are respectively inserted into the four positioning sleeves. When the third movable plate is manually driven to move away from the prism, the second tension spring is stretched, and the baffle moves relative to the second fixed plate, no longer contacting the top of the second fixed plate, thus releasing the restriction on the position of the second fixed plate. By manually driving the second fixed plate upwards, the third connecting plate drives the insertion rods upwards, thereby causing the insertion rods to disengage from the second through hole, releasing the restriction on the four... The position of the first fixed plate is defined, allowing the first fixed plate and the first lead screw to rotate. Manually driving the first lead screw to rotate causes it to move vertically relative to the threaded sleeve, thus changing the height of the four first lead screws. The bottom ends of the four first lead screws press against the swing seat, limiting its position and adjusting the angle of the swing seat, thereby adjusting the angle of the drilling rig body. After adjustment, manually driving the second fixed plate moves the insertion rod through the corresponding second through hole. The locking block is inserted into the locking slot, and the bottom end of the insertion rod is inserted into the positioning sleeve. The insertion rod limits the position of the first fixed plate, preventing rotation of the first fixed plate and the first lead screw due to non-human factors. The third movable plate is then released, and the second tension spring drives the third movable plate to move, causing the baffle to move. The bottom of the baffle contacts the top of the second fixed plate, preventing vertical wobbling of the second fixed plate and fixing it relative to the prism. The positioning sleeve design limits the position of the insertion rod, reducing the possibility of tilting or wobbling.

[0014] This invention also provides a method for exploring seabed rocks and polymetallic sulfides without tilting, including the aforementioned drilling rig for exploring seabed rocks and polymetallic sulfides without tilting, comprising the following steps:

[0015] The lifting device drives the movable ring to move upward, causing the third fixed plate to drive the four positioning plates and four support plates to move upward synchronously. The support plates drive the rotating roller and the first fixed plate to move upward, thereby causing the second movable plate to drive the insert plate to move upward. The bottom end of the insert plate disengages from the corresponding slot, releasing the fixed relationship between the sliding seat and the support plate, and the first tension spring is in a stretched state.

[0016] One of the sliding seats is manually driven to move, causing the sliding seat to slide relative to the support plate. The position of the roller is adjusted, and at the same time the second movable plate and the first fixed plate move with the sliding seat. The two ends of the rotating roller are rotatably connected to the first fixed plate and the second fixed plate, respectively. When the sliding seat moves, the rotating roller rolls on the top of the support plate.

[0017] When there is no need to adjust the position of the sliding seat, the manual drive of the tray moves away from the first fixed plate, so that the tray is no longer in contact with the rotating roller and the compression spring is in a compressed state. As the tray continues to move, when the tray is no longer directly below the rotating roller and the second fixed plate, the first tension spring drives the second movable plate to move down, so that the bottom end of the insert plate is inserted into the corresponding slot, thereby fixing the sliding seat relative to the support plate.

[0018] When the second movable plate descends, the second fixed plate and the first fixed plate move down with it. The support plate is located on the side of the second fixed plate away from the first fixed plate, and the support plate is in contact with the second fixed plate. Similarly, the positions of the remaining three sliding seats are adjusted. After the positions of the four sliding seats are adjusted, the movable ring is driven down by the lifting device, which in turn causes the third fixed plate and the support plate to move down. When the support plate is no longer in contact with one side of the second fixed plate, the compression spring drives the support plate to move, so that the support plate moves again to directly below the rotating roller, and the support plate returns to its initial position.

[0019] When the ground is uneven, the equipment box is moved upward by an external lifting device so that the rollers are no longer in contact with the ground. The position of the sliding seat is manually adjusted, thereby changing the position of the first movable plate. Through the design of the telescopic frame, the second toothed plate moves horizontally relative to the movable ring. Through the design of the sliding component, the second toothed plate slides vertically relative to the sliding seat.

[0020] When the sliding seat moves, the second toothed plate moves with the sliding seat, and the distance between the second toothed plate and the movable ring changes. The first movable plate is manually driven to move, so that the first movable plate moves vertically relative to the sliding seat, changing the height of the first movable plate and ensuring that the bottom of all four first movable plates are in contact with the ground. When the first movable plate moves, the first toothed plate drives the gear to rotate.

[0021] The lifting device drives the movable ring to move downward, which in turn drives the telescopic frame to move the second toothed plate downward. This causes the second toothed plate to mesh with the gear, preventing the gear from rotating and thus preventing the first toothed plate from moving vertically. This fixes the first movable plate relative to the sliding seat, thus fixing the height of the four first movable plates. This ensures that the bottom of all four first movable plates is in contact with the ground, supporting the equipment housing.

[0022] Compared with the prior art, the beneficial effects of the present invention are:

[0023] (1) The equipment box can be provided with water permeable holes, so that the equipment box is a hollow structure, which is convenient for water permeation and posture maintenance during the lowering process. The equipment box can be provided with hanging rings. The external lifting device can drive the equipment box to move through the hanging rings, so that the equipment box can move to the designated position. The equipment box is provided with interfaces for transmitting power and signals. Through the design of the lifting device, it is used to drive the movable ring to move vertically. By driving the movable ring to move upward through the lifting device, the third fixed plate drives the four positioning plates and four support plates to move upward synchronously. By driving the rotating roller and the first fixed plate to move upward through the support plate, the second movable plate drives the insertion plate to move upward. The bottom end of the insertion plate disengages from the corresponding slot, releasing the fixed relationship between the sliding seat and the support plate. The first tension spring is in the tension state. Manually drive one of the sliding seats to move, so that the sliding seat slides relative to the support plate. Adjust the position of the roller. At the same time, the second movable plate and the first fixed plate follow the sliding seat to move. The two ends of the rotating roller are rotatably connected to the first fixed plate and the second fixed plate respectively. When the sliding... When the seat moves, the rotating roller rolls on top of the support plate. When the position of the sliding seat does not need to be adjusted, the support plate is manually driven away from the first fixed plate, so that the support plate is no longer in contact with the rotating roller, and the compression spring is in a compressed state. As the support plate continues to move, when the support plate is no longer directly below the rotating roller and the second fixed plate, the first tension spring drives the second movable plate to move down, so that the bottom end of the insert plate is inserted into the corresponding slot, thus fixing the sliding seat relative to the support plate. When the second movable plate descends, the second fixed plate and the first fixed plate follow the second movable plate to move down, and the support plate is located on the side of the second fixed plate away from the first fixed plate, and the support plate is in contact with the second fixed plate. Similarly, the positions of the remaining three sliding seats are adjusted. After the positions of the four sliding seats are adjusted, the movable ring is driven down by the lifting device, which in turn causes the third fixed plate and the support plate to move down. When the support plate is no longer in contact with one side of the second fixed plate, the compression spring drives the support plate to move, so that the support plate moves back to directly below the rotating roller, so that the support plate returns to its initial position.

[0024] (2) When the ground is uneven, the equipment box is moved upward by an external lifting device so that the rollers are no longer in contact with the ground. The position of the sliding seat is manually adjusted, thereby changing the position of the first movable plate. Through the design of the telescopic frame, the second toothed plate moves horizontally relative to the movable ring. Through the design of the sliding component, the second toothed plate slides vertically relative to the sliding seat. When the sliding seat moves, the second toothed plate moves with the sliding seat, and the distance between the second toothed plate and the movable ring changes. The first movable plate is manually driven to move, so that the first movable plate moves vertically relative to the sliding seat, changing the position of the first movable plate. The height of the movable plates is adjusted to ensure that the bottom of all four movable plates is in contact with the ground. When the movable plates move, the first toothed plate drives the gear to rotate, which drives the movable ring to move down through the lifting device. This causes the telescopic frame to drive the second toothed plate to move down, thereby making the second toothed plate mesh with the gear. This prevents the gear from rotating and thus prevents the first toothed plate from moving vertically. As a result, the movable plates are fixed relative to the sliding seat, which completes the fixation of the height of the four movable plates. This ensures that the bottom of all four movable plates is in contact with the ground. The four movable plates support the equipment box and reduce the possibility of the equipment box tilting or swaying.

[0025] (3) The second screw is driven to rotate by the motor, and then the movable seat is driven to move by the second screw, thereby adjusting the distance between the movable seat and the swing seat. This allows the drill body to move relative to the swing seat, and drilling is performed by the drill body. The support frame is driven to move by the hydraulic telescopic rod, thereby adjusting the height of the movable ring.

[0026] (4) Through the design of the fixed block, spherical groove, fixed ball and connecting column, the swing seat can be rotated and connected to the equipment box in multiple directions. The third movable plate is manually driven to move away from the prism. The second tension spring is in the tension state, and the baffle moves relative to the second fixed plate. The baffle no longer contacts the top of the second fixed plate, releasing the limitation on the position of the second fixed plate. By manually driving the second fixed plate to move upward, the third connecting plate drives the insertion rod to move upward, thereby causing the insertion rod to disengage from the second through hole, releasing the limitation on the position of the four first fixed plates, allowing the first fixed plate and the first screw to rotate. By manually driving the first screw to rotate, the first screw moves vertically relative to the threaded sleeve, thereby changing the height of the four first screws. The bottom ends of the four first screws press against the swing seat. The position of the swing seat is limited by the four first screws. Adjust the angle of the swing seat, and then adjust the angle of the drilling rig body. After adjustment, manually drive the second fixed plate to move, so that the insertion rod passes through the corresponding second through hole, the locking block is inserted into the locking groove, and the bottom end of the insertion rod is inserted into the positioning sleeve. The insertion rod limits the position of the first fixed plate, preventing the first fixed plate and the first lead screw from rotating due to non-human factors. Release the third movable plate, and the second tension spring drives the third movable plate to move, so that the baffle moves. The bottom of the baffle contacts the top of the second fixed plate, preventing the second fixed plate from shaking vertically, so that the second fixed plate is fixed relative to the prism. Through the design of the positioning sleeve, the position of the insertion rod is limited, reducing the possibility of the insertion rod tilting and shaking. The equipment box is equipped with an umbilical cable. In this invention, it is not limited to manual drive. An electronic driver can be used to control the operation of the device on the ship through the deck unit. Attached Figure Description

[0039] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0040] Example 1, by Figures 1 to 9The invention includes a device housing 1 with permeable holes, making it a hollow structure to facilitate water permeation and posture maintenance during lowering. A swing seat 2 is located inside the housing 1. A first through hole 3 is formed on the bottom inner wall of the housing 1. A movable seat 4 is located at the bottom of the swing seat 2, and a drilling rig body 5 is located at the bottom of the movable seat 4. The housing 1 has interfaces for transmitting power and signals. The movable seat 4 and the swing seat 2 are connected by a spacing control mechanism. The swing seat 2 and the housing 1 are connected by a multi-directional... The rotating device is connected to the equipment housing 1, which is equipped with four first lead screws 7. The top of the first lead screw 7 passes through the top inner wall of the equipment housing 1. The first lead screw 7 is fitted with a threaded sleeve 6. The bottom of the threaded sleeve 6 is fixedly connected to the top of the equipment housing 1. The equipment housing 1 is equipped with a synchronous plug-in assembly that cooperates with the four first lead screws 7. The equipment housing 1 is equipped with an anti-tilt adjustment assembly. The equipment housing 1 can be equipped with a hanging ring. The external lifting device can drive the equipment housing 1 to move through the hanging ring, so that the equipment housing 1 moves to a designated position.

[0041] The anti-tilt adjustment assembly includes four sliding seats 8, which are respectively disposed on the four sides of the equipment housing 1. Support plates 11 are fixedly connected to each of the four sides of the equipment housing 1. Rollers 9 are provided at the bottom of each sliding seat 8. A first rectangular hole 10 is formed on each sliding seat 8, through which the support plate 11 passes. A movable ring 12 is fitted around the outside of the equipment housing 1, and the movable ring 12 is connected to the equipment housing 1 via a lifting mechanism. The sliding seats 8 and support plates 11 are connected via a lifting snap-fit ​​mechanism. A second rectangular hole 13 is formed on each sliding seat 8. First movable plates 14 are provided on each of the four sides of the equipment housing 1. 14 passes through the second rectangular hole 13. Two sliding grooves 15 are formed on the first movable plate 14. Two sliders 16 are fixedly connected to the inner wall of the second rectangular hole 13, with adjacent sliders 16 located within the two sliding grooves 15 respectively. A rotatably connected gear 17 is provided above the sliding seat 8. A first toothed plate 18 is fixedly connected to one side of the first movable plate 14. A second toothed plate 19 is provided above the gear 17. The second toothed plate 19 and the movable ring 12 are connected via a telescopic frame 20. The second toothed plate 19 and the sliding seat 8 are slidably connected via a sliding member 57. When the ground is uneven, the equipment housing 1 is moved upwards by an external lifting device. Once roller 9 is no longer in contact with the ground, the position of sliding seat 8 is manually adjusted, thereby changing the position of the first movable plate 14. Through the design of the telescopic frame 20, the second toothed plate 19 moves horizontally relative to the movable ring 12. Through the design of the sliding member 57, the second toothed plate 19 slides vertically relative to the sliding seat 8. When the sliding seat 8 moves, the second toothed plate 19 moves with it, changing the distance between the second toothed plate 19 and the movable ring 12. The first movable plate 14 is then manually driven to move vertically relative to the sliding seat 8, changing its height and ensuring the four... The bottom of each of the first movable plates 14 is in contact with the ground. When the first movable plate 14 moves, the first toothed plate 18 drives the gear 17 to rotate, and the movable ring 12 is driven to move down through the lifting device. This causes the telescopic frame 20 to drive the second toothed plate 19 to move down, thereby causing the second toothed plate 19 and the gear 17 to mesh, preventing the gear 17 from rotating and thus preventing the first toothed plate 18 from moving vertically. This fixes the first movable plate 14 relative to the sliding seat 8, thus fixing the height of the four first movable plates 14. This ensures that the bottom of each of the four first movable plates 14 is in contact with the ground, and the equipment housing 1 is supported by the four first movable plates 14.

[0042] Example 2, based on Example 1, is... Figure 1 , Figure 2 , Figure 3 , Figure 5 and Figure 6The lifting and snapping mechanism includes a second movable plate 21 disposed above a sliding seat 8. The sliding seat 8 has two insertion holes 22, and the support plate 11 has several slots 33. The second movable plate 21 and the sliding seat 8 are connected by several first tension springs 24. Two insert plates 23 are fixedly connected to the bottom of the second movable plate 21, passing through the insertion holes 22, and the bottom end of the insert plate 23 is inserted into one of the corresponding slots 33. The second movable plate 21 is provided with a lifting and sliding unit that cooperates with the movable ring 12. The lifting and sliding unit includes a first fixed plate 25 disposed on the top of the second movable plate 21, and the first fixed plate 25 is fixedly connected to the second movable plate 21. A second fixed plate 26 is provided on one side. The second fixed plate 26 and the first fixed plate 25 are connected by a first connecting plate 28. A support plate 29 is provided between the second movable plate 21 and the first connecting plate 28. A plurality of rotating rollers 27 are provided on the top of the support plate 29. The two ends of the rotating rollers 27 are rotatably connected to the first fixed plate 25 and the second fixed plate 26, respectively. The support plate 29 and the movable ring 12 are connected by a tension member. The tension member includes a third fixed plate 30 provided on one side of the support plate 29. One side of the third fixed plate 30 is fixedly connected to the movable ring 12. A positioning plate 31 is fixedly connected to one side of the support plate 29. The positioning plate 31 passes through the third fixed plate 30. The support plate 29 and the third fixed plate 30 are connected by a compression spring 32.

[0043] The lifting mechanism drives the movable ring 12 upward, causing the third fixed plate 30 to drive the four positioning plates 31 and four support plates 29 to move upward synchronously. The support plates 29 drive the rotating roller 27 and the first fixed plate 25 upward, thereby causing the second movable plate 21 to drive the insert plate 23 upward. The bottom end of the insert plate 23 disengages from the corresponding slot 33, releasing the fixed relationship between the sliding seat 8 and the support plate 11. The first tension spring 24 is in a stretched state. One of the sliding seats 8 is manually driven to move, causing the sliding seat 8 to slide relative to the support plate 11, adjusting the position of the roller 9. At the same time, the second movable plate 21 and the first fixed plate 25 move with the sliding seat 8. The two ends of the rotating roller 27 are rotatably connected to the first fixed plate 25 and the second fixed plate 26, respectively. When the sliding seat 8 moves, the rotating roller 27 rolls on the top of the support plate 29. When it is not necessary to adjust the position of the sliding seat 8, the support plate 29 is manually driven to move away from the first fixed plate 25, so that the support plate 29 is no longer in contact with the rotating roller 27, and the compression spring 32 is in a stretched state. In the compressed state, as the support plate 29 continues to move, when the support plate 29 is no longer directly below the rotating roller 27 and the second fixed plate 26, the first tension spring 24 drives the second movable plate 21 to move downward, so that the bottom end of the insert plate 23 is inserted into the corresponding slot 33, thereby fixing the sliding seat 8 relative to the support plate 11. When the second movable plate 21 descends, the second fixed plate 26 and the first fixed plate 25 follow the second movable plate 21 to move downward. The support plate 29 is located on the side of the second fixed plate 26 away from the first fixed plate 25, and the support plate 29 is in contact with the second fixed plate 26. Similarly, the positions of the remaining three sliding seats 8 are adjusted. After the positions of the four sliding seats 8 are adjusted, the movable ring 12 is driven downward by the lifting device, thereby causing the third fixed plate 30 and the support plate 29 to move downward. When the support plate 29 is no longer in contact with one side of the second fixed plate 26, the compression spring 32 drives the support plate 29 to move, so that the support plate 29 moves again to directly below the rotating roller 27, so that the support plate 29 returns to its initial position.

[0044] Example 3, based on Example 1, is... Figure 1 , Figure 4 and Figure 7The lifting device includes several hydraulic telescopic rods 35 disposed at the bottom of the equipment housing 1. The top of the hydraulic telescopic rods 35 is fixedly connected to the bottom of the equipment housing 1, and the bottom of the hydraulic telescopic rods 35 and the movable ring 12 are connected by a support frame 34. The spacing control mechanism includes two motors 37 disposed on the swing seat 2. The output end of the motors 37 is provided with a second lead screw 36, which passes through the swing seat 2 and the movable seat 4. The second lead screw 36 and the movable seat 4 are connected by a threaded connection. A second connecting plate 38 is provided below the movable seat 4. The second lead screw 36 and the second connecting plate 38 are connected by a bearing 39, and the drilling rig body 5 passes through the second connecting plate 38. The second lead screw 36 is driven to rotate by the motors 37, which in turn drives the movable seat 4 to move, thereby adjusting the distance between the movable seat 4 and the swing seat 2. This allows the drilling rig body 5 to move relative to the swing seat 2 and drill holes. The support frame 34 is driven to move by the hydraulic telescopic rods 35, thereby adjusting the height of the movable ring 12.

[0045] Example 4, based on Example 1, is... Figure 1 , Figure 8 and Figure 9 The multi-directional rotator includes a fixed block 40 disposed on the top of the swing seat 2, the fixed block 40 and the swing seat 2 are fixedly connected, the fixed block 40 has a spherical groove 41, the top inner wall of the equipment housing 1 is fixedly connected to a connecting column 43, the bottom end of the connecting column 43 is fixedly connected to a fixed ball 42, and the fixed ball 42 is located in the spherical groove 41. The synchronous insertion assembly includes a first fixed plate 44 disposed on the top of the first lead screw 7, the first fixed plate 44 and the first lead screw 7 are fixedly connected, the first fixed plate 44 has several second through holes 45, the top of the first fixed plate 44 is provided with an insertion rod 52, and the insertion rod 52 passes through one of the corresponding second through holes 45. The top of the equipment housing 1 is provided with a second fixed plate 46, and the insertion rod 52 and the second fixed plate 46 are connected by a third connecting plate 47. The bottom of the second fixed plate 46 is provided with a prism 48, the bottom of the prism 48 is fixedly connected to the top of the equipment box 1, the top of the prism 48 is provided with a slot 49, the bottom of the second fixed plate 46 is fixedly connected with a block 50, and the block 50 is inserted into the slot 49. The top of the second fixed plate 46 is provided with a baffle 51, one side of the baffle 51 is fixedly connected with a third movable plate 53, one side of the prism 48 is fixedly connected with two fixed posts 54, and the fixed posts 54 penetrate the third movable plate 53. The outside of the fixed posts 54 is fitted with a second tension spring 55, the two ends of the second tension spring 55 are fixedly connected to the prism 48 and the third movable plate 53 respectively, and the top of the equipment box 1 is fixedly connected with four positioning sleeves 56, the bottom ends of four insert rods 52 are respectively inserted into the four positioning sleeves 56.

[0046] Through the design of the fixed block 40, spherical groove 41, fixed ball 42, and connecting column 43, the swing seat 2 can be rotated in multiple directions relative to the equipment box 1. Manually driving the third movable plate 53 away from the prism 48, the second tension spring 55 is in a stretched state, and the baffle 51 moves relative to the second fixed plate 46. The baffle 51 no longer contacts the top of the second fixed plate 46, releasing the restriction on the position of the second fixed plate 46. Manually driving the second fixed plate 46 upwards causes the third connecting plate 47 to drive the insertion rod 52 upwards, thereby causing the insertion rod 52 to disengage from the second through hole 45, releasing the restriction on the position of the four first fixed plates 44. This allows the first fixed plates 44 and the first lead screw 7 to rotate. Manually driving the first lead screw 7 to rotate causes it to move vertically relative to the threaded sleeve 6, thereby changing the height of the four first lead screws 7. The bottom ends of the four first lead screws 7 press and swing. The position of the swing seat 2 is limited by four first lead screws 7, which can adjust the angle of the swing seat 2 and thus the angle of the drilling rig body 5. After adjustment, the second fixed plate 46 is manually driven to move, so that the insertion rod 52 passes through the corresponding second through hole 45. The locking block 50 is inserted into the locking groove 49, and the bottom end of the insertion rod 52 is inserted into the positioning sleeve 56. The position of the first fixed plate 44 is limited by the insertion rod 52 to prevent the first fixed plate 44 and the first lead screw 7 from rotating due to non-human factors. The third movable plate 53 is released, and the second tension spring 55 drives the third movable plate 53 to move, so that the baffle 51 moves. The bottom of the baffle 51 contacts the top of the second fixed plate 46 to prevent the second fixed plate 46 from shaking vertically, so that the second fixed plate 46 is fixed relative to the prism 48. Through the design of the positioning sleeve 56, the position of the insertion rod 52 is limited, reducing the possibility of the insertion rod 52 tilting and shaking.

[0047] This embodiment provides a method for exploring seabed rocks and polymetallic sulfides that prevents tilting, including the aforementioned anti-tilting seabed rock and polymetallic sulfide exploration drilling rig, and comprising the following steps:

[0048] The lifting device drives the movable ring 12 to move upward, which causes the third fixed plate 30 to drive the four positioning plates 31 and the four support plates 29 to move upward synchronously. The support plates 29 drive the rotating roller 27 and the first fixed plate 25 to move upward, which causes the second movable plate 21 to drive the insert plate 23 to move upward. The bottom end of the insert plate 23 disengages from the corresponding slot 33, releasing the fixed relationship between the sliding seat 8 and the support plate 11. The first tension spring 24 is in a stretched state.

[0049] One of the sliding seats 8 is manually driven to move, so that the sliding seat 8 slides relative to the support plate 11, and the position of the roller 9 is adjusted. At the same time, the second movable plate 21 and the first fixed plate 25 follow the sliding seat 8. The two ends of the rotating roller 27 are rotatably connected to the first fixed plate 25 and the second fixed plate 26 respectively. When the sliding seat 8 moves, the rotating roller 27 rolls on the top of the support plate 29.

[0050] When there is no need to adjust the position of the sliding seat 8, the manual drive of the support plate 29 moves away from the first fixed plate 25, so that the support plate 29 is no longer in contact with the rotating roller 27, and the compression spring 32 is in a compressed state. As the support plate 29 continues to move, when the support plate 29 is no longer directly below the rotating roller 27 and the second fixed plate 26, the first tension spring 24 drives the second movable plate 21 to move down, so that the bottom end of the insert plate 23 is inserted into the corresponding slot 33, thereby fixing the sliding seat 8 relative to the support plate 11.

[0051] When the second movable plate 21 descends, the second fixed plate 26 and the first fixed plate 25 follow the second movable plate 21 and move down. The support plate 29 is located on the side of the second fixed plate 26 away from the first fixed plate 25, and the support plate 29 is in contact with the second fixed plate 26. Similarly, the positions of the remaining three sliding seats 8 are adjusted. After the positions of the four sliding seats 8 are adjusted, the movable ring 12 is driven down by the lifting device, which causes the third fixed plate 30 and the support plate 29 to move down. When the support plate 29 is no longer in contact with one side of the second fixed plate 26, the compression spring 32 drives the support plate 29 to move, so that the support plate 29 moves again to directly below the rotating roller 27, so that the support plate 29 returns to its initial position.

[0052] When the ground is uneven, the equipment box 1 is moved upward by the external lifting equipment so that the roller 9 is no longer in contact with the ground. The position of the sliding seat 8 is manually adjusted, thereby changing the position of the first movable plate 14. Through the design of the telescopic frame 20, the second toothed plate 19 moves horizontally relative to the movable ring 12. Through the design of the sliding part 57, the second toothed plate 19 slides vertically relative to the sliding seat 8.

[0053] When the sliding seat 8 moves, the second toothed plate 19 moves with the sliding seat 8, and the distance between the second toothed plate 19 and the movable ring 12 changes. The first movable plate 14 is manually driven to move, so that the first movable plate 14 moves vertically relative to the sliding seat 8, changing the height of the first movable plate 14, ensuring that the bottom of all four first movable plates 14 are in contact with the ground. When the first movable plate 14 moves, the first toothed plate 18 drives the gear 17 to rotate.

[0054] The lifting device drives the movable ring 12 to move downward, which in turn drives the telescopic frame 20 to move the second toothed plate 19 downward. This causes the second toothed plate 19 to mesh with the gear 17, preventing the gear 17 from rotating and thus preventing the first toothed plate 18 from moving vertically. This fixes the first movable plate 14 relative to the sliding seat 8, thus fixing the height of the four first movable plates 14. This ensures that the bottom of the four first movable plates 14 is in contact with the ground, and supports the equipment housing 1 through the four first movable plates 14.

A method for exploring seabed rocks and polymetallic sulfides without tilting, comprising the anti-tilting seabed rock and polymetallic sulfide exploration drilling rig as described in claim 4, characterized in that: Includes the following steps: The lifting device drives the movable ring (12) to move upward, so that the third fixed plate (30) drives the four positioning plates (31) and the four support plates (29) to move upward synchronously. The support plates (29) drive the rotating roller (27) and the first fixed plate (25) to move upward, so that the second movable plate (21) drives the insert plate (23) to move upward. The bottom end of the insert plate (23) disengages from the corresponding slot (33), releasing the fixed relationship between the sliding seat (8) and the support plate (11). The first tension spring (24) is in a stretched state. Manually drive one of the sliding seats (8) to move, so that the sliding seat (8) slides relative to the support plate (11), adjust the position of the roller (9), and at the same time the second movable plate (21) and the first fixed plate (25) follow the sliding seat (8) to move. The two ends of the rotating roller (27) are rotatably connected to the first fixed plate (25) and the second fixed plate (26) respectively. When the sliding seat (8) moves, the rotating roller (27) rolls on the top of the support plate (29); When there is no need to adjust the position of the sliding seat (8), the manual drive plate (29) moves away from the first fixed plate (25) so that the plate (29) is no longer in contact with the rotating roller (27) and the compression spring (32) is in a compressed state. As the plate (29) continues to move, when the plate (29) is no longer directly below the rotating roller (27) and the second fixed plate (26), the first tension spring (24) drives the second movable plate (21) to move down, so that the bottom end of the insert plate (23) is inserted into the corresponding slot (33), and the sliding seat (8) is fixed relative to the support plate (11). When the second movable plate (21) descends, the second fixed plate (26) and the first fixed plate (25) follow the second movable plate (21) downwards. The support plate (29) is located on the side of the second fixed plate (26) away from the first fixed plate (25), and the support plate (29) is in contact with the second fixed plate (26). Similarly, the positions of the remaining three sliding seats (8) are adjusted. After the positions of the four sliding seats (8) are adjusted, the movable ring (12) is driven to move downwards by the lifting device, thereby causing the third fixed plate (30) and the support plate (29) to move downwards. When the support plate (29) is no longer in contact with one side of the second fixed plate (26), the compression spring (32) drives the support plate (29) to move, so that the support plate (29) moves again to the direct below the rotating roller (27), so that the support plate (29) returns to its initial position. When the ground is uneven, the equipment box (1) is moved up by an external lifting device so that the roller (9) no longer contacts the ground. The position of the sliding seat (8) is manually adjusted, thereby changing the position of the first movable plate (14). Through the design of the telescopic frame (20), the second toothed plate (19) moves horizontally relative to the movable ring (12). Through the design of the sliding part (57), the second toothed plate (19) slides vertically relative to the sliding seat (8). When the sliding seat (8) moves, the second toothed plate (19) moves with the sliding seat (8), and the distance between the second toothed plate (19) and the movable ring (12) changes. The first movable plate (14) is manually driven to move, so that the first movable plate (14) moves vertically relative to the sliding seat (8), and the height of the first movable plate (14) is changed to ensure that the bottom of all four first movable plates (14) are in contact with the ground. When the first movable plate (14) moves, the first toothed plate (18) drives the gear (17) to rotate. The lifting device drives the movable ring (12) to move down, which causes the telescopic frame (20) to drive the second toothed plate (19) to move down, thereby causing the second toothed plate (19) and the gear (17) to mesh, preventing the gear (17) from rotating, and thus preventing the first toothed plate (18) from moving vertically. This fixes the first movable plate (14) relative to the sliding seat (8), thus completing the fixation of the height of the four first movable plates (14), so that the bottom of the four first movable plates (14) are in contact with the ground, and the equipment box (1) is supported by the four first movable plates (14).
