Description

Technical Field

[0001] The present invention belongs to the technical field of offshore exploration, and in particular relates to an exploration equipment retracting and deploying device and a storage method for an offshore platform. Background Art

[0002] During offshore exploration, exploration equipment often needs to be retracted and deployed from an offshore platform. The exploration equipment retraction and deployment device primarily consists of a frame, a lifting cylinder, and a lifting platform. During operation, the lifting platform raises and lowers the exploration equipment, moving it into or out of the seawater. The lifting cylinder, located outside the lifting platform, reduces the risk of seawater directly impacting the exploration equipment, potentially causing shaking or even damage. It also prevents the exploration equipment from colliding with floating foreign objects.

[0003] During use of the existing exploration equipment retraction and deployment device, the lifting cylinder is generally through-hole-through from top to bottom. When the lifting cylinder is lowered into the water, if there are floating objects in the seawater below the lifting cylinder, the floating objects are likely to be trapped on the inner side of the lifting cylinder and hinder the exploration equipment from entering the water from the inner side of the lifting cylinder, or even collide with the exploration equipment and cause damage to the exploration equipment. The reliability of the exploration equipment retraction and deployment is insufficient, and the inner wall of the lifting cylinder is usually complete and without holes. When the seawater hits the lifting cylinder, the lifting cylinder is subjected to a large impact, which is easy to cause damage to the lifting cylinder, resulting in insufficient reliability. Summary of the Invention

[0004] The purpose of the present invention is to provide an exploration equipment retrieval and storage method for an offshore platform, which can reduce the damage caused by seawater impact to the lifting cylinder through a filter cylinder with a plurality of first water holes, improve reliability, and can prevent foreign objects from entering the inner side of the lifting cylinder through a baffle, thereby reducing the damage caused to the exploration equipment by collision between these floating objects and the exploration equipment.

[0015] As a preferred solution of the exploration equipment retraction device described in the present invention, the scraper is fixedly connected to a sliding bar on the side close to the baffle, and a sliding groove is provided on the side of the baffle close to the scraper. The sliding bar and the sliding groove are slidably matched, and a stopper is provided at one end of the sliding groove. A first bolt is passed through the inside of the stopper, and the end of the first bolt is threadedly connected to the baffle, and the stopper and the baffle are detachably connected by the first bolt.

[0016] As a preferred solution of the exploration equipment retracting and unfolding device described in the present invention, the lifting mechanism also includes a second electric drum fixedly connected to the frame, a second rope is wound around the second electric drum, and the end of the second rope away from the second electric drum is fixedly connected to the top plate, the lifting plate is installed below the top plate, and a plurality of limiting rollers are installed on the inner wall of the lifting cylinder, and the limiting rollers are in abutment with the second rope.

[0018] As a preferred solution of the exploration equipment retracting and extending device described in the present invention, a rotating arm is provided between the limiting roller and the inner wall of the lifting cylinder, the end of the rotating arm close to the limiting roller is rotatably connected to the limiting roller, the end of the rotating arm close to the lifting cylinder is rotatably connected to the inner wall of the lifting cylinder, a third motor is fixedly connected to the inner wall of the lifting cylinder, and the output end of the third motor is fixedly connected to the rotating arm.

[0019] A storage method for an offshore platform, which is applicable to the above-mentioned exploration equipment retracting and deploying device, is specifically as follows:

[0020] S1: First, place the exploration equipment retractable device on the offshore platform so that the lifting platform is aligned with the moon pool on the offshore platform, and place the exploration equipment on the lifting platform;

[0021] S2: When the exploration equipment needs to be lowered, the lifting cylinder descends to the water surface, and the lifting plate descends to allow the exploration equipment to enter the water;

[0022] S3: When the exploration equipment needs to be folded up, the lifting plate rises to allow the exploration equipment to leave the water, and the lifting cylinder rises to return to the frame from the water surface, so that the exploration equipment folding and unfolding device is stored on the offshore platform.

[0023] The technical effects achieved by the present invention are:

[0024] The present invention adopts a filter cartridge design. Since a plurality of first water holes are opened on the filter cartridge, when a portion of the lifting cartridge is located in the seawater, the seawater hits the casing mechanism, and a portion of the seawater passes through the first water holes and the openings on the lifting cartridge, rather than all of the seawater colliding with the casing mechanism. This reduces the impact of waves on the casing mechanism. Compared with the lifting cartridge with a complete inner wall without holes in the prior art, the present invention reduces the damage caused by the impact of seawater on the lifting cartridge, improves reliability, and facilitates the retraction and deployment of exploration equipment. Moreover, after the filter cartridge rotates along the baffle, floating objects on the outside of the lifting cartridge are blocked when they contact the filter cartridge, thereby reducing the accumulation of foreign matter caused by floating objects on the filter cartridge.

[0025] The present invention adopts a design of a baffle and a scraper. By adjusting the position of the rotatable baffle, it is not only convenient to prevent floating objects from entering the inner side of the lifting cylinder, but also convenient for the scraper to scrape and cut off foreign objects attached to the filter cylinder. When the baffle rotates along the lifting cylinder to the bottom of the lifting cylinder, the baffle prevents foreign objects in the water from entering the inner side of the lifting cylinder from the bottom of the lifting cylinder, thereby reducing the situation where these foreign objects collide with the exploration equipment and cause damage to the exploration equipment. When the baffle rotates along the lifting cylinder to the outside of the lifting cylinder, the baffle drives the scraper to rotate and fit with the outside of the filter cylinder, so that the scraper scrapes and cuts off foreign objects attached to the filter cylinder during the rotation of the filter cylinder along the lifting cylinder, thereby reducing the situation where foreign objects block the first water through hole on the filter cylinder and prevent seawater from passing through the filter cylinder.

[0026] The present invention adopts the design of a second rope and a limiting roller, which can not only limit the second rope through the limiting roller, but also absorb the seawater attached to the second rope to facilitate the second electric drum to reel in the second rope. When the second electric drum reels in the second rope or releases the second rope after work, causing the second rope to move up and down, the limiting roller limits the second rope in the transverse and longitudinal directions, thereby improving the stability of the second rope in moving up and down. When reeling in the second rope, since the second rope is still attached to seawater after being drawn out of the seawater, the limiting roller absorbs the seawater attached to the second rope, thereby reducing the situation where the second rope slips due to the seawater attached to it, which affects the reeling of the second electric drum, thereby improving the stability of the up and down movement of the exploration equipment and facilitating the retraction and deployment of the exploration equipment.

[0040] In order to make the purpose and advantages of the present invention more clearly understood, the present invention is described in detail below with reference to the following examples. It should be understood that the following text is only used to describe one or more specific embodiments of the present invention and does not strictly limit the scope of protection of the present invention.

[0041] Example 1: Figures 1 to 7 As shown in the figure, it is the first embodiment of the present invention. This embodiment provides an exploration equipment folding and unfolding device, including a frame 10; a lifting mechanism 20, the lifting mechanism 20 is arranged on the frame 10, and the lifting mechanism 20 includes a lifting plate 21 slidably installed on the frame 10 along the vertical direction; a casing mechanism 30, the casing mechanism 30 is arranged on the outside of the lifting plate 21, and the casing mechanism 30 includes a lifting cylinder 31 slidably installed on the frame 10 along the vertical direction, a filter cylinder 32 is rotatably installed on the outside of the lifting cylinder 31, and a plurality of baffles 33 are rotatably installed on the lower end of the lifting cylinder 31, and a scraper 34 is installed on the outside of the baffle 33, and the scraper 34 fits closely with the outside of the filter cylinder 32.

[0042] It should be noted that the lifting plate 21 is a conventional device used for placing exploration equipment (not shown in the figure). A second drainage hole is provided on the lifting plate 21 for allowing seawater to pass through the lifting plate 21 to reduce the obstruction of the seawater during the movement of the lifting plate 21. The lifting cylinder 31 is cylindrical and extends vertically. A plurality of first water holes are provided on the filter cylinder 32 for allowing seawater to pass through the filter cylinder 32. The lifting cylinder 31 has an opening near the water holes of the filter cylinder 32 for allowing seawater to pass through the lifting cylinder 31. Four baffles 33 are provided, each of which is a quarter circle. The baffles 33 are provided with a second water hole for allowing seawater to pass through the baffles 33. In the initial state, the lifting cylinder 31 is not in the water. The four baffles 33 are all rotated to the bottom of the lifting cylinder 31, and the four baffles 33 form a complete circle and cover the bottom of the lifting cylinder 31. The scraper 34 is arranged at an angle, and after the scraper 34 is tilted, the direction of the blade is opposite to the rotation direction of the filter cylinder 32, and the scraper 34 is used to rotate relative to the filter cylinder 32 to scrape and cut off foreign matter on the filter cylinder 32.

[0043] When the present invention is in use, when the exploration equipment needs to be placed in the water, the exploration equipment is placed on the lifting plate 21, and the lifting cylinder 31 slides downward along the frame 10 and approaches the water surface of the sea. Since the baffle 33 rotates to the bottom of the lifting cylinder 31, if there are floating objects on the sea surface below the lifting cylinder 31, the baffle 33 prevents the floating objects from entering the inner side of the lifting cylinder 31, thereby reducing the floating objects from being retained inside the lifting cylinder 31 and hindering the exploration equipment from entering the water from the inner side of the lifting cylinder 31, and reducing the collision of these floating objects with the exploration equipment and causing damage to the exploration equipment, thereby improving the reliability of the exploration equipment. Since the baffle 33 is provided with a second water hole, the lifting cylinder 31 can be opened. When the cylinder 31 and the baffle 33 enter the water, it is difficult for floating objects to enter the inner side of the cylinder 31, and seawater enters the inner side of the cylinder 31 through the second water hole, which facilitates the cylinder 31 and the baffle 33 to enter the seawater. The cylinder 31 and the baffle 33 continue to move downward, so that the lower end of the cylinder 31 enters the seawater, while the upper end of the cylinder 31 is still exposed above the water surface. The baffle 33 rotates outward along the cylinder 31, so that the baffle 33 pushes the foreign objects under the cylinder 31 to the outside, so that the bottom of the cylinder 31 is in an open state, which facilitates the lifting plate 21 to drive the exploration equipment to pass through the bottom of the cylinder 31, and the baffle 33 drives the scraper 34 to rotate outward. The scraper 34 fits into the outer side of the filter cylinder 32, and the lifting plate 21 slides downward along the frame 10. Since the bottom of the lifting cylinder 31 is in an open state, the baffle 33 no longer hinders the lifting plate 21 from moving downward, so that the lifting plate 21 drives the exploration equipment into the water. Since a plurality of first water holes are opened on the filter cylinder 32, when seawater hits the casing mechanism 30, the seawater passes through the first water holes and the openings on the lifting cylinder 31 to reduce the impact of waves on the casing mechanism 30. Compared with the prior art, the damage to the lifting cylinder 31 is reduced and the reliability is improved. After the filter cylinder 32 rotates along the lifting cylinder 31, floating objects are blocked when they contact the filter cylinder 32. The rotating filter drum 32 also rotates relative to the floating objects, reducing the accumulation of foreign matter caused by floating objects being retained on the filter drum 32. After the filter drum 32 rotates, it also rotates relative to the scraper 34, so that the scraper 34 moves along the outside of the filter drum 32 and scrapes and cuts off foreign matter attached to the filter drum 32, reducing the situation where foreign matter blocks the first water hole on the filter drum 32 and hinders seawater from passing through the filter drum 32. When the exploration equipment needs to be retracted from the seawater, the lifting plate 21 moves upward along the frame 10 to drive the exploration equipment out of the water, and the lifting drum 31 moves upward along the frame 10 and away from the water surface, thereby allowing the exploration equipment to be retracted from the seawater.

[0044] Example 2: Reference Figures 1 to 7 , which is the second embodiment of the present invention, and this second embodiment is based on the previous embodiment.

[0045] like Figure 1As shown, the lifting mechanism 20 also includes a plurality of first electric rollers 41 fixedly connected to the frame 10, and a first rope 42 is arranged between the first electric roller 41 and the lifting plate 21. The end of the first rope 42 close to the first electric roller 41 is wound around and connected to the first electric roller 41, and the end of the first rope 42 close to the lifting plate 21 is fixedly connected to the lifting plate 21.

[0046] It should be noted that four first electric rollers 41 are provided and distributed circumferentially around the axis of the lifting cylinder 31 . The first electric rollers 41 are conventional and are used to reel in or release the first rope 42 , which will not be described in detail here.

[0047] According to the above structure, after the first electric drum 41 works, the output end reels the first rope 42 or releases the first rope 42, so that the end of the first rope 42 away from the first electric drum 41 drives the lifting plate 21 to rise or fall, making it easier for the lifting plate 21 to rise or fall along the frame 10, thereby making it easier for the lifting plate 21 to drive the exploration equipment in and out of the sea water.

[0048] like Figure 1 、 Figure 2 、 Figure 6 and Figure 7 As shown, several telescopic cylinders 51 are fixedly connected to the frame 10, the lifting cylinder 31 is fixedly connected to the output end of the telescopic cylinder 51, a blocking cylinder 43 is slidably connected to the inner wall of the lifting cylinder 31, and a telescopic rod 44 is provided at one end of the blocking cylinder 43, the output end of the telescopic rod 44 is fixedly connected to the blocking cylinder 43, and the telescopic rod 44 is fixedly connected to the lifting cylinder 31.

[0049] It should be noted that the telescopic cylinder 51 is a prior art, and in the present invention it is preferably a telescopic hydraulic cylinder. The telescopic rod 44 is a prior art, and in the present invention it is preferably a telescopic electric rod. The outer wall of the retaining cylinder 43 and the inner wall of the lifting cylinder 31 slide together in the vertical direction. The retaining cylinder 43 is a cylinder that passes through from top to bottom, and is used to close the opening on the lifting cylinder 31 so that the interior of the lifting cylinder 31 forms a wave-proof cavity. In the initial state, the retaining cylinder 43 does not cover the opening on the lifting cylinder 31.

[0050] According to the above structure, since an opening is provided on the lifting cylinder 31 and a first water hole is provided on the filter cylinder 32, seawater can still pass through the lifting cylinder 31 and enter the inner side of the lifting cylinder 31. When it is necessary to reduce the entry of seawater into the inner side of the lifting cylinder 31, the output end of the telescopic cylinder 51 drives the blocking cylinder 43 to move along the lifting cylinder 31 and covers the opening on the lifting cylinder 31, thereby preventing seawater from entering the inner side of the lifting cylinder 31 through the opening on the lifting cylinder 31. When seawater is required to pass through the lifting cylinder 31 and the filter cylinder 32 to enter the inner side of the lifting cylinder 31, the output end of the telescopic cylinder 51 drives the blocking cylinder 43 to move along the lifting cylinder 31 away from the opening on the lifting cylinder 31. At this time, the blocking cylinder 43 no longer prevents seawater from entering the inner side of the lifting cylinder 31 through the opening on the lifting cylinder 31, thereby improving the applicability of the device.

[0051] like Figure 2 、 Figure 3 、 Figure 4 and Figure 6 As shown, the filter cylinder 32 is rotatably connected to the lifting cylinder 31 , a gear ring 52 is fixedly connected to the filter cylinder 32 , a first motor 53 is fixedly connected to the lifting cylinder 31 , and a gear 54 is fixedly connected to the output end of the first motor 53 , which meshes with the gear ring 52 .

[0052] It should be noted that the first motor 53 is a motor with forward and reverse rotation functions and self-locking functions. A convex edge is fixedly connected to the top of the filter cylinder 32, and a groove is provided on the lifting cylinder 31. The convex edge and the groove rotate in cooperation. The lifting cylinder 31 and the filter cylinder 32 are rotatably connected through the convex edge and the groove. A retaining ring is provided on the outside of the convex edge, and the retaining ring is fixedly connected to the lifting cylinder 31 to prevent the convex edge from sliding out of the groove to avoid the filter cylinder 32 from being separated from the lifting cylinder 31.

[0053] According to the above structure, when the filter cartridge 32 needs to rotate along the lifting cylinder 31, the output end of the first motor 53 drives the gear 54 to rotate after it works, and the gear 54 drives the filter cartridge 32 to rotate through the ring gear 52, thereby realizing the rotation of the filter cartridge 32 along the lifting cylinder 31, so as to reduce the accumulation of foreign matter caused by floating objects trapped on the filter cartridge 32.

[0054] like Figure 2 、 Figure 4 and Figure 6 As shown, the baffle 33 is rotatably connected to the lower end of the lifting cylinder 31 , the lifting cylinder 31 is fixedly connected to the second motor 55 , and the baffle 33 is fixedly connected to the output end of the second motor 55 .

[0055] It should be noted that the second motor 55 is a motor with forward and reverse rotation functions and a self-locking function.

[0056] According to the above structure, after the second motor 55 works, the output end drives the baffle 33 to rotate along the lifting cylinder 31. When the baffle 33 rotates to the bottom of the lifting cylinder 31, the baffle 33 prevents foreign matter in the seawater from entering the inner side of the lifting cylinder 31. When the baffle 33 rotates to the outer side of the lifting cylinder 31, the baffle 33 pushes away the foreign matter under the lifting cylinder 31 and drives the scraper 34 to fit the outer side of the filter cylinder 32, so that the scraper 34 can scrape and cut off the foreign matter on the filter cylinder 32.

[0057] like Figure 5 and Figure 7 As shown, a slide bar 56 is fixedly connected to the side of the scraper 34 close to the baffle 33, and a slide groove 57 is provided on the side of the baffle 33 close to the scraper 34. The slide bar 56 and the slide groove 57 slide together, and a stopper 58 is provided at one end of the slide groove 57. A first bolt 59 is passed through the interior of the stopper 58, and the end of the first bolt 59 is threadedly connected to the baffle 33. The stopper 58 and the baffle 33 are detachably connected through the first bolt 59.

[0058] It should be noted that the cross-sectional shapes of the slide bar 56 and the slide groove 57 are both dovetail-shaped or “T”-shaped, and the dovetail-shaped is preferred in the present invention.

[0059] The first bolt 59 is used to connect the block 58 to the baffle 33 so that the block 58 can prevent the slide bar 56 from sliding along the slide groove 57, and the block 58 can be placed at the end of the slide groove 57 to facilitate the removal of the scraper 34.

[0060] Example 3: Reference Figures 8 to 11 , which is the third embodiment of the present invention. This embodiment three is based on the embodiment one, and the difference is that: the lifting mechanism 20 also includes a second electric roller 61 fixedly connected to the frame 10, and a second rope 62 is wound around the second electric roller 61. The end of the second rope 62 away from the second electric roller 61 is fixedly connected to the top plate 63, and the lifting plate 21 is installed below the top plate 63. A plurality of limiting rollers 64 are installed on the inner wall of the lifting cylinder 31, and the limiting rollers 64 are in contact with the second rope 62.

[0061] It should be noted that the second electric roller 61 is an existing technology and is used to reel in or release the second rope 62, which will not be described in detail here. A second drainage hole is provided on the top plate 63 for seawater to pass through the top plate 63 to reduce the obstruction of seawater during the movement of the top plate 63. A strip hole is provided on the frame 10 near the second rope 62 for the second rope 62 to pass through the frame 10. Four limiting rollers 64 are provided, two of which are located on both sides of the second rope 62 in the transverse direction, and the other two limiting rollers 64 are located on both sides of the second rope 62 in the longitudinal direction. The limiting rollers 64 are made of water-absorbing material.

[0062] The second rope 62 is moved upwards relative to the limit roller 64 in the process of moving up and down relative to the frame 10, thereby improving the stability of the up and down movement of the second rope 62, thereby improving the stability of the up and down movement of the exploration equipment, and facilitating the retraction and deployment of the exploration equipment. In the process of rewinding the second rope 62, the second rope 62 moves upwards relative to the limit roller 64 in the sea water, and the limit roller 64 absorbs the sea water attached to the second rope 62, thereby reducing the slippage of the second rope 62 due to the sea water attached to the second rope 62, thereby affecting the rewinding of the second electric drum 61.

[0063] like Figure 9 and Figure 10 As shown, the bottom of the top plate 63 is fixedly connected with several first connecting columns 71, and the top of the lifting plate 21 is fixedly connected with several second connecting columns 72. The first connecting columns 71 and the second connecting columns 72 are slidably connected in the vertical direction. The first connecting column 71 is provided with several first limiting holes 73 in the vertical direction, and the second connecting column 72 is provided with second limiting holes 74. Second bolts 75 are passed through the first limiting holes 73 and the second limiting holes 74, and the ends of the second bolts 75 are threadedly connected with nuts 76. The first connecting column 71 and the second connecting column 72 are detachably mounted together by the second bolts 75 and the nuts 76.

[0064] It should be noted that a sliding hole is provided inside the second connecting column 72, and the sliding hole and the first connecting column 71 slide together in the vertical direction. The second connecting column 72 is slidably connected to the second connecting column 72 through the sliding hole.

[0065] When the distance between the top plate 63 and the lifting plate 21 needs to be adjusted, the second bolt 75 and the nut 76 are removed from the first limiting hole 73 and the second limiting hole 74, so that the limiting of the first connecting column 71 and the second connecting column 72 by the second bolt 75 and the nut 76 is released, and the second connecting column 72 is slid up and down along the first connecting column 71 to adjust the distance between the top plate 63 and the lifting plate 21 so that the second limiting hole 74 is aligned with the first limiting hole 73 at the appropriate position, and the second bolt 75 and the nut 76 are installed on the first limiting hole 73 and the second limiting hole 74 to limit the first connecting column 71 and the second connecting column 72 so that the relative position between the top plate 63 and the lifting plate 21 remains fixed, thereby adjusting the distance between the top plate 63 and the lifting plate 21, making it easy to adapt to exploration equipment of different heights and sizes and improving applicability.

[0066] like Figure 8 and Figure 9 As shown, a rotating arm 81 is provided between the limiting roller 64 and the inner wall of the lifting cylinder 31, and the end of the rotating arm 81 close to the limiting roller 64 is rotatably connected to the limiting roller 64, and the end of the rotating arm 81 close to the lifting cylinder 31 is rotatably connected to the inner wall of the lifting cylinder 31. A third motor 82 is fixedly connected to the inner wall of the lifting cylinder 31, and the output end of the third motor 82 is fixedly connected to the rotating arm 81.

[0067] It should be noted that, in the initial state, the rotating arm 81 rotates to the outside to reduce the situation where the rotating arm 81 and the limiting roller 64 hinder the top plate 63 and the lifting plate 21 from moving up and down inside the lifting cylinder 31.

[0068] According to the above structure, in the process of placing the exploration equipment into the sea, after the top plate 63 and the lifting plate 21 drive the exploration equipment to move downward through the limiting roller 64, the second rope 62 also passes through the limiting roller 64. After the third motor 82 is operated, the output end drives the rotating arm 81 to rotate inward, and the rotating arm 81 drives the limiting roller 64 from both sides of the second rope 62 to approach the second rope 62, so as to facilitate limiting the second rope 62. In the process of retrieving the exploration equipment from the sea, when the top plate 63 and the lifting plate 21 drive the exploration equipment to pass through the limiting roller 64, the output end of the third motor 82 is operated and drives the rotating arm 81 to rotate outward, and the rotating arm 81 drives the limiting roller 64 away from the second rope 62, so that the rotating arm 81 and the limiting roller 64 no longer hinder the top plate 63 and the lifting plate 21 from moving upward, so that the top plate 63 and the lifting plate 21 can drive the exploration equipment to continue to move upward for retraction.

[0069] In order to enable those skilled in the art to have a further understanding of the exploration equipment retracting and unfolding device of the present invention, the present invention further provides a storage method for an offshore platform, which is applicable to the above-mentioned exploration equipment retracting and unfolding device. The specific method is as follows:

[0070] S1: First, place the exploration equipment retractable device on the offshore platform so that the lifting platform 21 is aligned with the moon pool on the offshore platform, and place the exploration equipment on the lifting platform 21;

[0071] S2: When the exploration equipment needs to be lowered, the lifting cylinder 31 is lowered to the water surface, and the lifting plate 21 is lowered to allow the exploration equipment to enter the water;

[0072] S3: When the exploration equipment needs to be folded up, the lifting plate 21 rises to allow the exploration equipment to leave the water, and the lifting cylinder 31 rises and returns from the water surface to the frame 10, so that the exploration equipment folding device is stored on the offshore platform.

[0073] The working principle of the present invention is as follows: the lifting cylinder 31 is lowered into the seawater along the frame 10, so that a part of the lifting cylinder 31 is exposed above the water surface. During this process, the baffle 33 located at the bottom of the lifting cylinder 31 prevents foreign matter in the seawater below the lifting cylinder 31 from entering the inner side of the lifting cylinder 31, and after the baffle 33 rotates outward along the lifting cylinder 31, it is convenient to push the floating objects below the lifting cylinder 31 outward. The baffle 33 also drives the scraper 34 to rotate and makes the scraper 34 fit the outer side of the filter cylinder 32. The filter cylinder 32 rotates along the lifting cylinder 31. Afterwards, not only is it reduced that floating objects are retained on the filter cartridge 32 and cause foreign matter accumulation, but the scraper 34 is also moved along the outer side of the filter cartridge 32 to scrape and cut off foreign matter attached to the filter cartridge 32, reducing the situation where foreign matter blocks the first water holes on the filter cartridge 32 and hinders seawater from passing through the filter cartridge 32. Since a plurality of first water holes are provided on the filter cartridge 32, it is convenient for seawater to pass through the lifting cylinder 31 and the filter cartridge 32. Compared with the lifting cylinder 31 with a complete inner wall without holes in the prior art, the damage caused to the lifting cylinder 31 by the impact of seawater is reduced.

[0074] The foregoing is merely a preferred embodiment of the present invention. It should be noted that those skilled in the art may make various improvements and modifications without departing from the principles of the present invention, and such improvements and modifications are also within the scope of protection of the present invention. Structures, devices, and operating methods not specifically described or explained herein shall, unless otherwise specified or limited, be implemented in accordance with conventional means in the art.
