Specifically, the protection device includes a wave-dissipating and ice-breaking assembly, and the wave-dissipating and ice-breaking assembly includes a first housing and a first connecting portion. A plurality of wave-dissipating holes are formed in the side wall of the first housing. For the specific structure of the wave-dissipating holes, the present invention is configured such that the plurality of wave-dissipating holes penetrate through the first housing in the thickness direction of the first housing, that is, the wave-dissipating holes are through holes formed in the first housing. The plurality of wave-dissipating holes are used for reducing waves.

After installation, the second connecting portion and the first connecting portion form an integral body. One end of the second connecting portion abuts against the pile leg, that is, for the protection device proposed by the present invention, the first housing provided with wave dissipation holes is arranged on the pile leg through the connection of the first connecting portion and the second connecting portion.
[0010] The first housing is sleeved on the pile leg through the first connecting portion and the second connecting portion, so that the first housing and the pile leg are detachably connected. Furthermore, it is more convenient to adjust the position of the first housing, and it is also convenient for maintenance and replacement. On the basis of protecting the pile leg of the pile-type platform, it is possible to conveniently inspect and maintain the protection device for protecting the pile leg.

The inner wall of the third mounting hole abuts against the pile leg, and the second connecting portion is arranged on the support plate; a fourth connecting portion, which can pass through the second mounting hole and the fourth mounting hole and is connected to the inner walls of the second mounting hole and the fourth mounting hole.
[0012] In this technical solution, the wave dissipation and ice breaking assembly further includes a third connecting portion, and the third connecting portion is connected to one end of the first housing away from the first mounting portion. Specifically, along the height direction of the wave dissipation and ice breaking assembly, the wave dissipation and ice breaking assembly successively includes the first connecting portion, the first housing, and the third connecting portion.
[0013] A second mounting hole is formed in the third connecting portion. The second mounting hole is a hole structure for the installation of the third connecting portion.

Among them, the inner wall of the third mounting hole abuts against the pile leg. The support plate can be sleeved on the pile leg through the third mounting hole and is relatively stable. The second connecting portion is arranged on the support plate, so that both ends of the first housing are connected and supported, and thus the pile leg can be protected more stably.
[0015] The protection device further includes a fourth connecting portion, which can pass through the second mounting hole and the fourth mounting hole and is connected to the inner walls of the second mounting hole and the fourth mounting hole. Through the fourth connecting portion, the connection and separation between the support portion and the second connecting portion can be realized, so that the first housing is also detachably connected to the pile leg at the other end, thereby improving the convenience of use of the first housing.
[0016] In any of the above technical solutions, the inner peripheral surface of the first housing and the outer peripheral surface of the pile leg are spaced apart in the inner and outer directions, so as to form a gap between the inner peripheral surface of the first housing and the outer peripheral surface of the pile leg; drain holes are formed in the support plate, and the drain holes penetrate through the support plate in the thickness direction of the support plate, and the drain holes are used to drain the seawater in the wave-dissipating and ice-breaking assembly.
[0017] In this technical solution, the inner peripheral surface of the first housing and the outer peripheral surface of the pile leg are spaced apart in the inner and outer directions, so as to form a gap between the inner peripheral surface of the first housing and the outer peripheral surface of the pile leg, and the first housing can protect the pile leg; drain holes are formed in the support plate. Specifically, the drain holes penetrate through the support plate in the thickness direction of the support plate, and the drain holes are used to drain the seawater in the wave-dissipating and ice-breaking assembly. By providing the drain holes on the support plate, excessive water accumulation between the first housing and the pile leg can be avoided, and the situation of excessive extrusion of the pile leg by seawater can be avoided.
[0018] In some technical solutions, optionally, ice-breaking holes are formed in the side wall of the first housing, and the ice-breaking holes penetrate through the side wall of the first housing in the thickness direction of the first housing. The wave-dissipating and ice-breaking assembly further includes: an ice-breaking mechanism, and the ice-breaking mechanism includes a second housing, a driving part and an ice-breaking thimble. The second housing is arranged on the support plate and is located between the first housing and the pile leg; the driving part is arranged on the second housing; the ice-breaking thimble is movably arranged in the second housing and is connected to the driving part, and one end of the ice-breaking thimble faces the ice-breaking hole; the ice-breaking thimble can move radially on the second housing under the drive of the driving part. Among them, the ice-breaking thimble has a first position and a second position. In the first position, the ice-breaking thimble is located inside the second housing, and in the second position, the ice-breaking thimble passes through the ice-breaking hole to extend out of the second housing for ice-breaking.
[0019] In this technical solution, ice-breaking holes are formed in the side wall of the first housing, and the ice-breaking holes penetrate through the side wall of the first housing in the thickness direction of the first housing, so as to connect the inside of the first housing with the external environment, and the ice-breaking holes are specifically used for ice-breaking operations.
[0020] The wave-dissipating and ice-breaking assembly further includes an ice-breaking mechanism. Specifically, the ice-breaking mechanism includes a second housing, a driving part and an ice-breaking thimble. The second housing is an external structural member of the ice-breaking mechanism. The second housing is arranged on the support plate and is located between the first housing and the pile leg, specifically in the gap formed between the first housing and the pile leg.
[0021] The driving part is arranged on the second housing, so that the driving part is fixed.
[0022] The ice-breaking thimble activity is arranged on the second housing and connected to the driving part. One end of the ice-breaking thimble faces the ice-breaking hole. The ice-breaking thimble can move radially along the second housing under the drive of the driving part. Among them, the ice-breaking thimble has a first position and a second position. Specifically, the first position is the retracted position, and the second position is the ice-breaking position. In the first position, the ice-breaking thimble is located inside the second housing. In the second position, the ice-breaking thimble passes through the ice-breaking hole to extend out of the second housing, and the ice-breaking thimble breaks the ice and acts on the sea ice to break the sea ice.
[0023] During the use process, by driving the movement of the ice-breaking thimble through the driving part, the accumulated sea ice can be crushed, and the broken sea ice can flow away with the ocean current, thereby reducing the load of the sea ice on the pile leg.
[0024] In any of the above technical solutions, optionally, the driving part includes: a hydraulic cylinder; a hydraulic rod, which is movably arranged in the hydraulic cylinder, and one end of the hydraulic rod is connected to the ice-breaking thimble.
[0025] In this technical solution, the driving part specifically includes a hydraulic cylinder and a hydraulic rod. The hydraulic rod is movably arranged in the hydraulic cylinder, and one end of the hydraulic rod is connected to the ice-breaking thimble. By using a hydraulic structure to drive the ice-breaking thimble, it is possible to not only make the ice-breaking thimble obtain a driving force to work, but also make the working process of the ice-breaking thimble specifically controllable. The operator can control the ice-breaking thimble by controlling the hydraulic cylinder, so that the ice-breaking thimble moves between the first position and the second position, which can not only retract the ice-breaking thimble into the second housing, but also make the ice-breaking thimble pass through the ice-breaking hole and move to the ice-breaking position, realizing targeted ice-breaking according to the situation of the ice layer and avoiding excessive accumulation of ice blocks and squeezing the pile leg.
[0026] In any of the above technical solutions, optionally, the ice-breaking mechanism further includes: a limiting part, and the limiting part includes: a spring; a spring fixing rod, which is movably arranged on the second housing, the spring is sleeved on the spring fixing rod, the spring fixing rod is connected to the ice-breaking thimble; a fixing ring plate, which is arranged on the second housing, and a communication hole is opened on the fixing ring plate, the spring fixing rod passes through the communication hole, and the inner diameter of the spring is larger than the diameter of the communication hole; the spring fixing rod can move with the ice-breaking thimble, and one end of the spring abuts against the fixing ring plate, so that the ice-breaking thimble moves between the first position and the second position.
[0027] In this technical solution, the present invention provides that the ice-breaking mechanism further includes a limiting part, and the limiting part includes a spring, a fixed ring plate and a spring fixing rod. The spring is sleeved on the spring fixing rod. The spring fixing rod can be driven by the ice-breaking thimble to move in the second housing through the communication hole on the fixed ring plate. The inner diameter of the spring is larger than the diameter of the communication hole. One end of the spring abuts against the fixed ring plate. Specifically, when the spring is sleeved on the spring fixing rod, it is located at the end of the fixed ring plate away from the ice-breaking hole. Then, during the movement of the spring fixing rod, one end of the spring is clamped with the fixed ring plate, so that the spring fixing rod cannot move further, thereby limiting the ice-breaking thimble and enabling the ice-breaking thimble to move radially between the first position and the second position within a certain range, avoiding the ice-breaking thimble moving out of the ice-breaking hole.
[0028] The ice-breaking mechanism further includes: a limiting part, which is arranged on the second housing and is movably connected to the ice-breaking thimble, and is used for limiting the ice-breaking thimble so that the ice-breaking thimble moves radially along the second housing between the first position and the second position.
[0029] In this technical solution, the present invention provides that the ice-breaking mechanism further includes a limiting part, which is specifically arranged on the second housing and is movably connected to the ice-breaking thimble. The limiting part is used for limiting the ice-breaking so that the ice-breaking thimble moves between the first position and the second position, that is, the telescopic movement of the ice-breaking thimble in the ice-breaking hole is limited within a certain range, avoiding the ice-breaking thimble moving out of the ice-breaking hole and also avoiding the ice-breaking thimble tilting and moving and unable to penetrate the ice-breaking hole. Finally, it can be realized that under the drive of the driving part, the ice-breaking thimble makes a telescopic movement in the ice-breaking hole to break the ice.
[0030] In any of the above technical solutions, optionally, the first housing includes a first sub-shell and a second sub-shell connected to each other. The free end of the first sub-shell is connected to the first connecting part, and the free end of the second sub-shell is connected to the third connecting part; the cross-sectional area of the outer peripheral surface of the first sub-shell gradually increases in the direction away from the first connecting part, and the cross-section of the outer peripheral surface of the second sub-shell gradually increases in the direction away from the third connecting part; a plurality of wave-dissipating holes are evenly distributed on the first sub-shell and the second sub-shell.
[0031] In this technical solution, for the specific shape of the first housing, the present application is set such that the first housing includes two connected parts. Specifically, the first housing includes a first sub-shell and a second sub-shell connected to each other. Among them, when arranged on the pile leg, along the gravity direction, the second sub-shell is located below the first sub-shell.
[0032] The free end of the first sub-shell is connected to the first connecting part, and the free end of the second sub-shell is connected to the third connecting part, thereby realizing the arrangement of the first housing on the pile leg.
[0033] The cross-sectional area of the outer peripheral surface of the first sub-shell gradually increases in the direction away from the first connecting portion, and the cross-section of the outer peripheral surface of the second sub-shell gradually increases in the direction away from the third connecting portion. That is, along the direction of gravity, the first housing is a housing structure that is wider in the middle and narrower at both ends. Through the above-described setting of the shape of the first housing, the first housing can have better stability when disposed on the pile leg, guide the seawater when the seawater flows through, and can better resist lateral pressure and torque, and better protect the pile leg.
[0034] A plurality of wave-dissipating holes are evenly distributed on the first sub-shell and the second sub-shell. The plurality of wave-dissipating holes are arranged on the first housing along the circumferential direction of the first housing. Since the first sub-shell and the second sub-shell are inclined, the seawater can be attenuated when entering the wave-dissipating holes, and the wave-dissipating holes can play a role in dissipating waves.
[0035] In any of the above technical solutions, optionally, the number of ice-breaking mechanisms corresponds to the number of ice-breaking holes, and one end of an ice-breaking thimble faces one ice-breaking hole.
[0036] In this technical solution, the number of ice-breaking mechanisms corresponds to the number of ice-breaking holes. That is, when there are four ice-breaking holes, the number of ice-breaking mechanisms is four, and when there are five ice-breaking holes, the number of ice-breaking mechanisms is five.
[0037] In terms of the setting position, one end of an ice-breaking thimble faces one ice-breaking hole, and an ice-breaking thimble can extend out at one ice-breaking hole, achieving an improved ice-breaking effect and at the same time avoiding component interference when different ice-breaking mechanisms are working.
[0038] In any of the above technical solutions, optionally, the protection device further includes: a first buffer pad disposed between the first connecting portion and the pile leg; a second buffer pad disposed between the inner wall of the third mounting hole and the pile leg.
[0039] In this technical solution, the protection device further includes a first buffer pad and a second buffer pad. Among them, the first buffer pad is disposed between the first connecting portion and the pile leg. The first buffer pad can act between the first connecting portion and the pile leg. When the ice squeezes the first connecting portion, the first buffer pad can deform to absorb the impact force sent by the first connecting portion to the pile leg, thereby avoiding the situation that the pile leg is damaged by a large impact force, and achieving better protection for the pile leg.
[0040] The second buffer pad is disposed between the inner wall of the third mounting hole and the pile leg. The second buffer pad can act between the support portion and the pile leg. When the ice squeezes the support portion, the second buffer pad can deform to absorb the impact force sent by the support portion to the pile leg, thereby avoiding the situation that the pile leg is damaged by a large impact force, and achieving better protection for the pile leg.
[0041] In any of the above technical solutions, optionally, the protection device further includes: an anti-corrosion coating coated on the outer peripheral surface of the first housing.
[0042] In this technical solution, the present invention also coats an anti-corrosion coating on the outer peripheral surface of the first housing. The anti-corrosion coating has strong anti-corrosion properties, which can enable the first housing to resist the corrosion of seawater, thereby having a longer service life.

[0057] The protection device 100 proposed by the present invention can be applied to a pile-type platform to provide protection for the pile legs 200 of the pile-type platform. It can solve the technical problem in the related art that the engineering cannot resist the coupled impact of wind, waves and currents on the pile legs 200. Specifically, the protection device 100 includes a wave-dissipating and ice-breaking component 110, and the wave-dissipating and ice-breaking component 110 includes a first housing 112 and a first connecting portion 118. A plurality of wave-dissipating holes 114 are formed in the side wall of the first housing 112. For the specific structure of the wave-dissipating holes 114, the present invention is configured such that the plurality of wave-dissipating holes 114 penetrate the first housing 112 in the thickness direction of the first housing 112, that is, the wave-dissipating holes 114 are through holes formed in the first housing 112. The plurality of wave-dissipating holes 114 are used to reduce waves. Specifically, the wave-dissipating holes 114 provided on the side wall of the first housing 112 can disperse and absorb the energy of the sea waves when the sea waves impact.
[0058] The first connecting portion 118 is connected to the first housing 112. The first connecting portion 118 is specifically a component for installing the first housing 112. In terms of shape, the first connecting portion 118 is annular, and thus can be more adapted to the pile legs 200 of the pile-type platform.
[0059] The first connecting portion 118 and the second housing 132 are disposed around the pile legs 200, and thus can protect the pile legs 200 and prevent the sea waves from impacting the pile legs 200.
[0060] The protection device 100 further includes a second connecting portion. The second connecting portion can pass through a first mounting hole 120 formed in the first connecting portion 118, and the first connecting portion 118 can be connected to the inner wall of the first mounting hole 120. The second connecting portion and the first connecting portion 118 form an integral body after installation. One end of the second connecting portion abuts against the pile legs 200, that is, for the protection device 100 proposed by the present invention, the first housing 112 provided with the wave-dissipating holes 114 is disposed on the pile legs 200 through the connection of the first connecting portion 118 and the second connecting portion.
[0061] The first housing 112 is sleeved on the pile legs 200 through the first connecting portion 118 and the second connecting portion, so that the first housing 112 and the pile legs 200 are detachably connected. Furthermore, it is more convenient to adjust the position of the first housing 112, and it is also convenient for maintenance and replacement. On the basis of protecting the pile legs 200 of the pile-type platform, it is possible to conveniently inspect and maintain the protection device for protecting the pile legs 200.
[0062] Specifically, when installing the first housing 112 on the leg 200, first, the first connecting portion 118 is sleeved on the leg 200, and then the second connecting portion is passed through the first mounting hole 120 opened on the first connecting portion 118 to connect the second connecting portion and the leg 200, thereby installing the first housing 112 on the leg 200. When it is necessary to remove the first housing 112 from the leg 200, the second connecting portion is pulled out from the first mounting hole 120, thereby separating the first housing 112 from the leg 200, and the disassembly and assembly process is convenient.
[0063] Specifically, the first mounting hole 120 is a threaded hole, and the second connecting portion is a screw rod. The threads provided on the two can be combined with each other, and then they are stably connected together.
[0064] Such as Figure 1 、 Figure 2 and Figure 3 As shown in
[0065] In this embodiment, the wave dissipating and ice breaking assembly 110 further includes a third connecting portion 180, which is connected to one end of the first housing 112 away from the first connecting portion 118. Specifically, along the height direction of the wave dissipating and ice breaking assembly 110, the first connecting portion 118, the first housing 112, and the third connecting portion 180 are arranged in sequence.
[0066] The third connecting portion 180 is provided with a second mounting hole 182. The second mounting hole 182 is a hole structure for installing the third connecting portion 180. Specifically, the second mounting hole 182 penetrates through the third connecting portion 180 along the thickness direction of the third connecting portion 180.
[0067] The protection device 100 further includes a support plate 160. The support plate 160 is provided with a third mounting hole 162 and a fourth mounting hole. The inner wall of the third mounting hole 162 abuts against the leg 200. The support plate 160 can be sleeved on the leg 200 through the third mounting hole 162 and is relatively stable. The second connecting portion is arranged on the support plate 160, so that both ends of the first housing 112 are connected and supported, and thus the leg 200 can be protected more stably.
[0068] The protection device 100 further includes a fourth connecting portion. The fourth connecting portion can pass through the second mounting hole 182 and the fourth mounting hole and be connected to the inner walls of the second mounting hole 182 and the fourth mounting hole. Through the fourth connecting portion, the connection and separation between the support portion and the second connecting portion can be realized, so that the other end of the first housing 112 is also detachably connected to the pile leg 200, thereby improving the usability of the first housing 112.
[0069] Specifically, the support plate 160 is a semi-circular plate body.
[0070] Specifically, at the third mounting hole 162, the support plate 160 is provided with a support plate connecting portion 164. A threaded hole of the support plate connecting portion 164 is formed on the support plate connecting portion 164. When the support plate 160 is arranged on the pile leg 200, a connecting member such as a bolt is inserted into the threaded hole of the support plate connecting portion 164, the thread on the bolt is combined with the thread of the threaded hole of the support plate connecting portion 164, and one end of the bolt abuts against the pile leg 200 to fix the support plate 160.
[0071] The fourth mounting hole is a threaded hole, and the fourth connecting portion is a screw rod. The threads formed on them can be combined with each other, and then they are stably connected together.
[0072] Specifically, the fourth mounting hole is formed on the outer ring of the support plate 160.
[0073] Specifically, the number of both the second mounting hole 182 and the fourth mounting hole is multiple. The multiple fourth mounting holes are evenly distributed on the outer ring of the support plate 160 along the circumferential direction of the support plate 160. The number of the fourth connecting portions is multiple. During installation, through the cooperation of the multiple second mounting holes 182, the fourth mounting holes and the multiple fourth mounting portions, the third connecting portion 180 can be arranged on the support plate 160 more stably.
[0074] Such as Figure 7 and Figure 8 As shown in, in some embodiments, optionally, the inner peripheral surface of the first housing 112 and the outer peripheral surface of the pile leg 200 are spaced apart in the inner and outer directions to form a gap between the inner peripheral surface of the first housing 112 and the outer peripheral surface of the pile leg 200; a drain hole 170 is formed on the support plate 160. The drain hole 170 penetrates through the support plate 160 along the thickness direction of the support plate 160. The drain hole 170 is used to drain the seawater in the wave-dissipating and ice-breaking assembly 110.
[0075] In this embodiment, the inner circumferential surface of the first housing 112 and the outer circumferential surface of the pile leg 200 are spaced apart in the inner and outer directions, so as to form a gap between the inner circumferential surface of the first housing 112 and the inner circumferential surface of the pile leg 200, and the first housing 112 can protect the pile leg 200. Drainage holes 170 are formed in the support plate 160. Specifically, the drainage holes 170 penetrate the support plate 160 in the thickness direction of the support plate 160, and the drainage holes 170 are used to drain the seawater in the wave-dissipating and ice-breaking assembly 110. By means of the drainage holes 170 provided on the support plate 160, it is possible to avoid excessive accumulation of water between the first housing 112 and the pile leg 200, and avoid the occurrence of the situation where seawater excessively squeezes the pile leg 200.

The wave-dissipating and ice-breaking assembly 110 further includes: an ice-breaking mechanism 130, and the ice-breaking mechanism includes a second housing 132, a driving part 136 and an ice-breaking ejector pin 142.

Among them, the ice-breaking ejector pin 142 has a first position and a second position. In the first position, the ice-breaking ejector pin 142 is located inside the second housing 132. In the second position, the ice-breaking ejector pin 142 passes through the ice-breaking hole 116 to extend out of the second housing 132 for ice-breaking.
[0077] In this embodiment, ice-breaking holes 116 are formed in the side wall of the first housing 112, and the ice-breaking holes 116 penetrate the side wall of the first housing 112 in the thickness direction of the first housing 112, so as to connect the inside of the first housing 112 with the external environment, and the ice-breaking holes 116 are specifically used for ice-breaking operations.
[0078] The wave-dissipating and ice-breaking assembly 110 further includes an ice-breaking mechanism 130. Specifically, the ice-breaking mechanism 130 includes a second housing 132, a driving part 136 and an ice-breaking ejector pin 142. The second housing 132 is an external structural member of the ice-breaking mechanism 130. The second housing 132 is arranged on the support plate 160 and is located between the first housing 112 and the pile leg 200, specifically in the gap formed between the first housing 112 and the pile leg 200.
[0079] The driving part 136 is arranged on the second housing 132, so that the driving part 136 is fixed.
[0080] The ice-breaking thimble 142 is movably arranged on the second housing 132 and is connected to the driving part 136. One end of the ice-breaking thimble 142 faces the ice-breaking hole 116. The ice-breaking thimble 142 can move radially along the second housing 132 on the second housing 132 under the drive of the driving part 136. Among them, the ice-breaking thimble 142 has a first position and a second position. Specifically, the first position is the retracted position, and the second position is the ice-breaking position. In the first position, the ice-breaking thimble 142 is located inside the second housing. In the second position, the ice-breaking thimble 142 passes through the ice-breaking hole 116 to extend out of the second housing 132, and the ice-breaking thimble 142 acts on the sea ice to break the sea ice.
[0081] During use, by driving the movement of the ice-breaking thimble 142 through the driving part 136, the accumulated sea ice can be crushed, and the broken sea ice can flow away with the ocean current, thereby reducing the load of the sea ice on the pile leg 200.
[0082] As Figure 4 shown, in some embodiments, optionally, the driving part 136 includes: a hydraulic cylinder 138: a hydraulic rod 140, which is movably arranged in the hydraulic cylinder 138, and one end of the hydraulic rod 140 is connected to the ice-breaking thimble 142.
[0083] In this embodiment, the driving part 136 specifically includes a hydraulic cylinder 138 and a hydraulic rod 140. The hydraulic rod 140 is movably arranged in the hydraulic cylinder 138, and one end of the hydraulic rod 140 is connected to the ice-breaking thimble 142. By using a hydraulic structure to drive the ice-breaking thimble 142, it is possible to not only make the ice-breaking thimble 142 obtain a driving force to work, but also make the working process of the ice-breaking thimble 142 specifically controllable. The operator can control the ice-breaking thimble 142 by controlling the hydraulic cylinder 138, so that the ice-breaking thimble 142 moves between the first position and the second position, that is, the ice-breaking thimble 142 is retracted into the second housing 132, and the ice-breaking thimble 142 is also moved to the ice-breaking position through the ice-breaking hole 116, realizing targeted ice-breaking according to the situation of the ice layer and avoiding excessive accumulation of ice blocks to squeeze the pile leg 200.
[0084] As Figure 3 、 Figure 4 、 Figure 5 and Figure 6As shown, in some embodiments, the ice-breaking mechanism 130 further includes: a limiting portion 144, and the limiting portion 144 includes: a spring 146; a spring fixing rod 154, the spring 146 is sleeved on the spring fixing rod 154, and the spring fixing rod 154 is connected to the ice-breaking thimble 142; a fixed ring plate 148, which is arranged on the second housing 132, and a communication hole 152 is formed on the fixed ring plate 148, the spring fixing rod 154 passes through the communication hole 152, and the inner diameter of the spring 146 is larger than the diameter of the communication hole 152; the spring fixing rod 154 can move along with the ice-breaking thimble 142, and one end of the spring 146 can abut against the fixed ring plate 148, so that the ice-breaking thimble 142 moves between a first position and a second position.
[0085] In this embodiment, the present invention provides that the ice-breaking mechanism 130 further includes a limiting portion 144, and the limiting portion 144 includes a spring 146, a fixed ring plate 148 and a spring fixing rod 154. The spring 146 is sleeved on the spring fixing rod 154, and the spring fixing rod 154 passes through the communication hole 152 on the fixed ring plate 148 and can be driven by the ice-breaking thimble 142 to move in the second housing 132.
[0086] The inner diameter of the spring 146 is larger than the diameter of the communication hole 152, and one end of the spring 146 can abut against the fixed ring plate 148. Specifically, when the spring 146 is sleeved on the spring fixing rod 154, it is located at one end of the fixed ring plate 148 away from the ice-breaking hole 116. Furthermore, during the movement of the spring fixing rod 154, one end of the spring 146 is clamped with the fixed ring plate 148, so that the spring fixing rod 154 cannot move further, thereby limiting the ice-breaking thimble 142 and enabling the ice-breaking thimble 142 to move radially between a first position and a second position within a certain range, avoiding the ice-breaking thimble 142 from moving out of the ice-breaking hole 116.
[0087] Specifically, a sixth mounting hole 150 is formed on the fixed ring plate 148, and by passing a bolt through the sixth mounting hole 150, the fixed ring plate 148 can be arranged on the second housing 132. Specifically, the sixth mounting hole 150 is a threaded hole.
[0088] Specifically, the surface of the second housing 132 is coated with an anti-corrosion coating, and the material of the second housing 132 is steel.
[0089] Specifically, a fifth mounting hole 134 is formed on the second housing 132, and a ninth mounting hole 168 is arranged on the support plate 160. By passing a bolt through the fifth mounting hole 134 and the ninth mounting hole 168, the second housing 132 is arranged on the support plate 160. Specifically, the fifth mounting hole 134 and the ninth mounting hole 168 are threaded holes.
[0090] Such as Figure 1 、 Figure 2 and Figure 3As shown, in any of the above embodiments, optionally, the first housing 112 includes a first sub-housing 190 and a second sub-housing 192 that are connected to each other. The free end of the first sub-housing 190 is connected to the first connecting portion 118, and the free end of the second sub-housing 192 is connected to the third connecting portion 180. The cross-sectional area of the outer peripheral surface of the first sub-housing 190 gradually increases in a direction away from the first connecting portion 118, and the cross-section of the outer peripheral surface of the second sub-housing 192 gradually increases in a direction away from the third connecting portion 180. A plurality of wave-dissipating holes 114 are evenly distributed on the first sub-housing 190 and the second sub-housing 192.
[0091] In this embodiment, for the specific shape of the first housing 112, the present application is configured such that the first housing 112 includes two interconnected parts. Specifically, the first housing 112 includes a first sub-housing 190 and a second sub-housing 192 that are connected to each other. When disposed on the pile leg 200, the second sub-housing 192 is located below the first sub-housing 190 along the direction of gravity.
[0092] The free end of the first sub-housing 190 is connected to the first connecting portion 118, and the free end of the second sub-housing 192 is connected to the third connecting portion 180, thereby realizing the setting of the first housing 112 on the pile leg.
[0093] The cross-sectional area of the outer peripheral surface of the first sub-housing 190 gradually increases in a direction away from the first connecting portion 118, and the cross-section of the outer peripheral surface of the second sub-housing 192 gradually increases in a direction away from the third connecting portion 118, that is, along the direction of gravity, the first housing 112 is a housing structure that is wider in the middle and narrower at both ends. Through the above setting of the shape of the first housing 112, the first housing 112 can have better stability when disposed on the pile leg 200, guide the seawater, and can better resist lateral pressure and torque, and better protect the pile leg 200.
[0094] A plurality of wave-dissipating holes 114 are evenly distributed on the first sub-housing 190 and the second sub-housing 192. The plurality of wave-dissipating holes 114 are arranged on the first housing 112 along the circumferential direction of the first housing 112. Since the first sub-housing 190 and the second sub-housing 192 are inclined, the seawater can be attenuated when entering the wave-dissipating holes 114, and the wave-dissipating holes 114 can play a wave-dissipating role.
[0095] As Figure 1 、 Figure 2 and Figure 3 As shown, in any of the above embodiments, optionally, the number of ice-breaking mechanisms 130 corresponds to the number of ice-breaking holes 116, and one end of an ice-breaking thimble 142 faces one ice-breaking hole 116.
[0096] In this embodiment, the number of ice-breaking mechanisms 130 corresponds to the number of ice-breaking holes 116. That is, when there are four ice-breaking holes 116, the number of ice-breaking mechanisms 130 is four; when there are five ice-breaking holes 116, the number of ice-breaking mechanisms 130 is five.
[0097] In terms of the setting position, one end of an ice-breaking thimble 142 faces one ice-breaking hole 116, and the ice-breaking thimble 142 can extend out at one ice-breaking hole 116, which improves the ice-breaking effect and at the same time avoids component interference when different ice-breaking mechanisms 130 are working.
[0098] Specifically, along the circumferential direction of the first housing 112, four ice-breaking holes 116 are evenly arranged on the side wall of the first housing 112, that is, the ice-breaking holes 116 on the first housing 112 are oriented in four directions. The ice-breaking mechanisms 130 are arranged in all four directions, thereby realizing four-way ice-breaking. No matter from which direction the ice in the sea water impacts the side wall of the first housing 112, the ice-breaking mechanisms 130 can break the ice.
[0099] In any of the above embodiments, optionally, the protection device 100 further includes: a first buffer pad disposed between the first connection portion 118 and the pile leg 200; a second buffer pad disposed between the inner wall of the third mounting hole 162 and the pile leg 200.
[0100] In this embodiment, the protection device 100 further includes a first buffer pad and a second buffer pad. Among them, the first buffer pad is disposed between the first connection portion 118 and the pile leg 200. The first buffer pad can act between the first connection portion 118 and the pile leg 200. When the ice squeezes the first connection portion 118, the first buffer pad can deform to absorb the impact force sent from the first connection portion 118 to the pile leg 200, thereby avoiding the situation that the pile leg 200 is damaged by a large impact force and achieving better protection for the pile leg 200.
[0101] The second buffer pad is disposed between the inner wall of the third mounting hole 162 and the pile leg 200. The second buffer pad can act between the support portion and the pile leg 200. When the ice squeezes the support portion, the second buffer pad can deform to absorb the impact force sent from the support portion to the pile leg 200, thereby avoiding the situation that the pile leg 200 is damaged by a large impact force and achieving better protection for the pile leg 200.
[0102] In any of the above embodiments, optionally, the protection device 100 further includes an anti-corrosion coating, and the anti-corrosion coating is coated on the outer peripheral surface of the first housing.
[0103] In this embodiment, an anti-corrosion coating is further provided on the outer peripheral surface of the first housing 112. The anti-corrosion coating has strong anti-corrosion properties, which can enable the first housing 112 to resist the corrosion of seawater, thereby having a longer service life.
[0104] Specifically, the anti-corrosion coating is provided to cover the first housing 112, that is, the anti-corrosion coating is applied to the surface of the first housing 112, so as to comprehensively resist the corrosion of the first housing 112 by seawater.
[0105] Specifically, when using the protection device 100 proposed by the present invention, first, the second housing 132 of the ice-breaking mechanism 130 is fixed to the support plate 160 with bolts. The ice-breaking mechanism 130 needs to be installed in four directions. After the ice-breaking mechanism 130 is fixed to the support plate 160, bolts are then used to pass through the eighth mounting holes 166 opened on the support plate connecting portion 164 to fix the support plate 160 to the pile leg 200. Then, the second connecting portion is used to fix the first connecting portion 118 and the first housing 112 to the pile leg 200 through the first mounting holes 120. Then, the fourth connecting portion passes through the second mounting holes 182 and the fourth mounting holes to fix the third connecting portion 180, the first housing 112 and the support plate 160 together.
[0106] Wave-dissipating and ice-breaking working process: The seawater passing through the wave-dissipating holes 114 will consume its energy. At this time, the scouring force of the seawater impacting the pile leg 200 will be reduced. In addition, rubber pads are provided on the inner sides of the first connecting portion 118 and the support plate 160, which can relieve the impact load. When the sea ice reaches the outer edge of the wave-dissipating and ice-breaking assembly 110, the thinner sea ice will break during the extrusion process and then float away with the seawater. When encountering larger sea ice or the accumulation of sea ice, the personnel on the upper part of the platform will control, and the ice-breaking mechanism 130 will start to work. The hydraulic cylinder 138 provides hydraulic pressure, which is transmitted to the ice-breaking thimble 142 by the hydraulic rod 140. Through the hydraulic action, the ice-breaking thimble 142 extends through the ice-breaking hole 116, so that the ice-breaking thimble 142 moves from the first position to the second position. The sea ice cracks and breaks under the extrusion force and the action of the ice-breaking thimble 142, and then floats away with the seawater. The limiting structure can limit the displacement of the ice-breaking thimble 142.
