[0002] In many fields such as marine engineering, marine fisheries and offshore power generation platforms, steel pipes or pipe piles play a vital role. They are used as key supporting structures to cope with various complex marine environments and conditions. These structures not only bear huge upper loads, such as the weight of the platform or dock, the impact of ships and the scouring of seawater, but also have to withstand the test of natural forces such as tides, waves and currents.

[0020] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.
[0021] It should be noted that when an element is referred to as being "fixed to" or "disposed on" another element, it can be directly on the other element or indirectly on the other element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or indirectly connected to the other element.

[0023] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of this application, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.
[0024] like Figure 1 As shown, the specific technical solution of a protective sleeve for isolating seawater provided in an embodiment of the present application is as follows:
[0025] A sleeve 1, the upper end of which is provided with a pipe pile clamping device 2; the pipe pile clamping device 2 comprises a plurality of radial sliding components 3 and a lifting component 4 for driving a slider 31 of the radial sliding component 3 to slide synchronously;
[0026] A plurality of mounting blocks 7 are respectively arranged on the side surfaces of the sleeve 1 ; the mounting blocks 7 are slidably provided with an up-and-down moving assembly 5 for driving the lifting assembly 4 to move.
[0027] The utility model provides a protective sleeve for isolating seawater. Compared with the prior art, the utility model drives the lifting block 41 of the lifting assembly 4 to move up and down through the up and down moving assembly 5. The up and down movement of the lifting block 41 causes multiple sliders 31 to slide synchronously, thereby clamping the lower end of the pipe pile in the sleeve 1.
[0028] In another embodiment of the present application, Figure 1As shown, each radial sliding assembly 3 includes a radial track 32 and a slider 31; the slider 31 is slidably connected to the radial track 32. The sliding connection between the slider 31 and the radial track 32 can be achieved in a variety of ways, such as using lubricants, ball bearings or other friction-reducing materials to reduce friction and improve the smoothness of sliding. In addition, in order to ensure the stability of the slider 31 on the radial track 32, some limit devices or guide structures may also need to be set to limit the movement range of the slider 31 or provide a correct sliding direction.
[0029] In another embodiment of the present application, Figure 1 As shown, a plurality of support columns 311 are respectively disposed on both sides of the slider 31. The support columns 311 are located on the side of the slider 31 facing away from the lifting assembly 4, that is, the side opposite to the lifting assembly 4. All the support columns 311 are connected to a clamping block 33 in common.
[0030] In another embodiment of the present application, Figure 1 As shown, the lifting assembly 4 includes a lifting column 42 and a lifting block 41 ; the lifting column 42 is disposed in the middle of the plurality of radial tracks 32 , and the lifting block 41 is slidably connected to the lifting column 42 .
[0031] In another embodiment of the present application, Figure 1 As shown, one side of the lifting block 42 is connected to a plurality of connecting rods 6 by means of an articulation. The number of these connecting rods 6 is consistent with the number of the sliders 31, and the plurality of connecting rods 6 are arranged in a circular array around the lifting block 42. One end of each connecting rod 6 is articulated to the lifting block 42, and the other end is articulated to the corresponding slider 31.
[0032] This hinge design allows the connecting rod 6 to transmit force and motion between the lifting block 42 and the slider 31. When the lifting block 42 moves on the lifting column 42, the slider 31 can be driven to slide on the radial track 32 through the hinge relationship between the connecting rod 6 and the slider 31. This linkage mechanism enables the lifting motion of the lifting block 42 to be converted into the radial sliding of the slider 31, thereby realizing the coordinated work of lifting and radial sliding.
[0033] It should be noted that, although the embodiment describes that one end of the connecting rod 6 is hinged to the lifting block 42 and the other end is hinged to the slider 31, this does not constitute the only limitation on the connection mode of the connecting rod 6. In fact, the connection mode of the connecting rod 6 can be adjusted and optimized accordingly according to specific needs and application scenarios. For example, different motion transmission effects can be achieved by changing the length, angle or position of the hinge point of the connecting rod 6.
[0034] In another embodiment of the present application, Figure 1As shown, the up-and-down moving assembly 5 mainly includes a driving source 51 and a moving rod 52. The driving source 51 is arranged on the offshore platform, and its function is to provide power for the moving rod 52 to move up and down. When the driving source 51 is activated, it can drive the moving rod 52 to move up and down along its axial direction. This design allows the moving rod 52 to be accurately adjusted in the vertical direction, thereby meeting various practical application requirements.
[0035] Furthermore, in order to achieve power transmission between the driving source 51 and the moving rod 52, a gear is connected to the output end of the driving source 51. At the same time, a rack is provided near the gear on the moving rod 52. The rack is meshed with the gear, so that when the driving source 51 rotates the gear, the rack is driven by the gear and moves along its axial direction, thereby driving the moving rod 52 to move up and down.
[0036] This power transmission method realized by the gear and rack has the advantages of simple structure, stable transmission, reliable operation, etc. At the same time, due to the meshing relationship between the gear and the rack, the accuracy and stability of the moving rod 52 during the up and down movement can also be guaranteed.
[0037] It should be noted that, although the present embodiment describes that the driving source 51 drives the moving rod 52 to move up and down through the gear and rack, this does not constitute the only implementation method of the up and down moving assembly 5. In fact, according to specific needs and application scenarios, other transmission methods or structures can also be used to achieve the up and down movement of the moving rod 52. Therefore, the description in this embodiment should be regarded as an exemplary implementation method rather than a restrictive definition. For example: Electric push rod or cylinder : Use an electric push rod or an air cylinder as a driving source, directly connected to the moving rod 52. When the electric push rod or the air cylinder is extended or retracted, they push or pull the moving rod 52 to move up and down. Ball Screw : A ball screw nut is installed on the moving rod 52 and matched with the screw shaft. The driving source 51 (such as a motor) drives the screw shaft to rotate through the reduction mechanism. Due to the high transmission efficiency of the ball screw, the moving rod 52 will move up and down along the screw shaft.
[0038] In another embodiment of the present application, Figure 1 As shown, a plurality of lugs are arranged around the sleeve 1, and these lugs are used to connect the lifting ropes. The lugs are a structure used to connect or fix the lifting equipment such as ropes and chains, and they usually have sufficient strength and stability to ensure that they will not fall off or break during the lifting or hanging process.
[0039] In actual operation, the sleeve 1 needs to be sunk after avoiding the pipe pile, and then the lower end of the pipe pile is aligned with the upper end of the sleeve 1 after the sleeve 1 is moved, and the sleeve 1 is put on the lower end of the pipe pile through the lifting rope, and the driving source 51 is operated to realize the clamping of the pipe pile by the canned sleeve 1. Then, the seawater in the sleeve 1 can be pumped out by the upper pump.

In addition, under the teachings of the present invention, these features and embodiments may be modified to adapt to specific circumstances and materials without departing from the spirit and scope of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed herein, and all embodiments falling within the scope of the claims of this application are within the scope of protection of the present invention.
