Description

Technical Field

[0001] This invention relates to the field of marine engineering equipment technology, and in particular to a chain stopper for a floating power generation platform at sea. Background Technology

[0002] With the increasing development of new energy sources at sea, floating wind power and ocean energy platforms are becoming more widely used due to their suitability for deep-sea operations. These platforms need to be fixed in the sea by mooring systems. As a core component of the mooring system, the chain stopper plays a crucial role in adjusting the tension of the anchor chain and stopping the anchor chain in emergencies. Its performance directly affects the stability and safety of the platform in complex sea conditions.

[0003] Currently, traditional chain stoppers for offshore platforms mostly use a fixed structural design, which has obvious limitations: First, they lack adaptability. Traditional chain stoppers have fixed anchor chain specifications, making it difficult to flexibly adjust them according to different platform sizes, water depths, and current conditions. When facing diverse construction schemes and load requirements from customers, redesign and manufacturing are required, leading to increased costs and extended cycles. Second, they have poor stability. Some chain stoppers use a single chain locking mechanism, lacking a symmetrical and coordinated action mechanism. Under extreme conditions such as typhoons and giant waves (e.g., wave heights exceeding 7m and wind speeds reaching 60m / s), problems such as chain loosening or excessive compression of the anchor chain can easily occur. Furthermore, slewing supports are mostly seated installations, requiring complex pontoon structures and quick-release mechanisms, increasing system redundancy and failure risks. Third, they are inconvenient to maintain and install. Traditional devices have low component integration, cumbersome on-site assembly steps, and key components such as drive mechanisms and chain guide components are susceptible to seawater corrosion and have insufficient corrosion resistance, resulting in high maintenance frequency and costs, making it difficult to meet the 20-year design life requirements of the platform.

[0004] Furthermore, existing chain stoppers have shortcomings in dynamic tension adjustment. Most rely solely on a single winch or chain-stopping mechanism, failing to achieve real-time and precise control of anchor chain tension. When sea state changes cause drastic fluctuations in anchor chain tension, this can easily lead to anchor chain fatigue damage or mooring system instability. Simultaneously, some chain stoppers lack effective redundancy design, making it difficult to quickly restore functionality through external intervention in the event of critical component failures, thus failing to meet the safety requirements of CCS and other standards for critical offshore equipment. Therefore, developing a chain stopper with strong adaptability, high stability, convenient maintenance, and dynamic tension adjustment capabilities has become an urgent need to address the current pain points of mooring systems for offshore floating power generation platforms. Summary of the Invention

[0005] The purpose of this invention is to provide a chain stopper for offshore floating power generation platforms to solve the above-mentioned problems. It solves the problems of insufficient adaptability, poor stability under extreme sea conditions, cumbersome maintenance and installation, weak dynamic tension adjustment capability, and lack of effective redundancy guarantee of traditional chain stoppers, and meets the requirements of efficient, reliable and long-term operation of chain stopper equipment in the mooring system of offshore floating power generation platforms.

The bottom of the first connecting seat is fixedly connected to one side of the top surface of the base. The bottom of the second connecting seat is fixedly connected to the other side of the top surface of the base. There are two fixing sleeves, which are respectively fixedly connected to the center interior of the first and second connecting seats. The two sides of the connecting shaft are respectively movably connected to the interior of the corresponding fixing sleeves, and one side of the connecting shaft is connected to the chain stop drive mechanism. The lower side of the chain locking arm is located between the first and second connecting seats, and the interior of the lower side of the chain locking arm is fixedly connected to the outside of the connecting shaft by a key. A chain locking groove is provided on the upper side of the chain locking arm. The limiting seat is located on the lower side of the chain locking arm, and the bottom of the limiting seat is fixedly connected to the center of the top surface of the base. The limiting block is located on the outside of the limiting seat and is fixedly connected to the bottom of the chain locking arm.

[0009] Preferably, the chain stop drive mechanism includes a mounting sleeve 1, a fixing screw 1, a connecting block 1, a connecting rod, a mounting sleeve 2, a fixing screw 2, a connecting head 1, a connecting block 2, a connecting head 2, a hydraulic cylinder, a connecting head 3, and a connecting block 3. The mounting sleeve 1 is fixedly connected to the input end of the chain stop mechanism 1 by several fixing screws 1. A connecting block 1 is fixedly connected to the lower side of the mounting sleeve, and a connecting block 3 is fixedly connected to the upper side of the mounting sleeve 1. The mounting sleeve 2 is fixedly connected to the input end of the chain stop mechanism 2 by several fixing screws 2. A connecting block 2 is fixedly connected to the upper side of the mounting sleeve 2. A connecting head 1 is fixedly connected to both ends of the connecting rod.

A connecting head 3 is fixedly connected to the other end of the hydraulic cylinder, and the connecting head 3 is hinged to the upper side of the connecting block 3.

[0010] Preferably, both the first fixing screw and the second fixing screw are internal hexagon screws.

[0011] Preferably, the chain guide mechanism includes a locking plate, three fixing screws, a locking groove, a fixing shaft, and a chain wheel; the fixing shaft is movably connected to the lower interior of the mounting groove, and several locking grooves are formed on both sides of the outer perimeter of the fixing shaft; the chain wheel is located inside the mounting groove, and its center is movably connected to the outside of the fixing shaft; there are several locking plates, each of which is fixedly connected to both sides of the mounting groove by several fixing screws, and the inner sides of the locking plates are connected to the inner sides of the corresponding locking grooves.

[0012] Preferably, the fixing screw three is a hexagonal screw.

[0013] Preferably, protective railings are fixedly connected to both sides of the upper side of the mounting slot.

[0014] The beneficial effects of the present invention are: (1) The present invention has a reasonable and simple structure, low production cost and convenient installation, and complete functions. It can provide stable support for the chain transmission of offshore floating power generation platforms. Through the protective railing on the upper side of the installation slot, it can effectively prevent personnel from accidentally falling into the slot or debris from entering the slot during offshore operations, and effectively ensure the safety of equipment and personnel. At the same time, the outer shell can completely wrap the chain-related mechanism to avoid the corrosion of internal components by seawater and sea wind, and ensure that the device maintains a stable installation posture in the sea wind and wave environment without significant shaking or displacement.

[0015] (2) The present invention achieves chain clamping and release by synchronously responding to the drive mechanism command through two symmetrically arranged chain clamping mechanisms. In addition, the cooperation of the limit block and the limit seat can limit the excessive rotation of the chain clamping arm, avoid damage to the chain or chain clamping arm due to excessive clamping force, and ensure the safety and reliability of the chain stopping action. At the same time, the drive mechanism transmits power through the coordinated transmission of multiple components to ensure that the two chain clamping mechanisms move synchronously and oppositely, effectively avoiding chain stopping failure due to the mismatch of the two sides. There is no jamming or abnormal noise in the power transmission process, and each hinge point rotates flexibly, ensuring stable power transmission.

[0016] (3) The chain guide mechanism of the present invention can continuously play a guiding role during chain transmission. The chain guide wheel rotates synchronously with the chain, which can reduce the frictional loss between the chain and the chain guide mechanism, and ensure that the chain transmission is smooth without jamming or deviation.

[0017] (4) When the floating power generation platform is operating normally, the present invention does not interfere with the normal operation of the chain. In case of emergency or when the chain transmission needs to be suspended, the chain stop action can be quickly triggered by the control system, so that the chain slot can quickly fit and lock the chain. After the chain stop is completed, the chain can be reset by the reverse action of the drive mechanism, so that the chain can resume normal transmission. This achieves efficient guidance and reliable stopping of the chain, and meets the adjustment operation needs of the floating power generation platform. Attached Figure Description

Detailed Implementation

[0027] like Figure 1 As shown, this specific embodiment adopts the following technical solution: a chain stopper for an offshore floating power generation platform, including a platform 1 as the overall installation base, a chain stopper 2 to realize the anchor chain stopping function, an installation groove 3 to provide installation space for each component, and a chain guide mechanism 4 to assist in the guiding and transmission of the anchor chain; the installation groove 3 is opened along the outer edge of the platform 1, and the size of the groove is adapted to the installation requirements of the chain stopper 2 and the chain guide mechanism 4; the chain stopper 2 is fixedly connected to the top of the opening of the installation groove 3 by bolt assembly to ensure that it maintains a stable position in the sea environment; the chain guide mechanism 4 is movably connected to the lower interior of the installation groove 3 to facilitate the guidance of the anchor chain.

[0028] like Figure 2 As shown, the chain-stopping device 2 includes a base 21 for supporting and fixing, two symmetrically arranged chain-locking mechanisms 22 and 25, a chain-stopping drive mechanism 23 for providing power drive, and an outer shell 24 to protect the internal components. The bottom of the base 21 is double-fixed to the inner side of the top surface of the mounting groove 3 by welding and bolts to improve the connection strength. The bottoms of the chain-locking mechanisms 22 and 25 are symmetrically distributed and fixed to both sides of the top surface of the base 21 by bolts, with the distance between them adapted to the anchor chain transmission path. The outer shell 24 is made of stainless steel and covers the outside of the chain-locking mechanisms 22 and 25. Its bottom is fixed to the upper edge of the base 21 by a combination of sealing strips and bolts to effectively prevent seawater and salt corrosion. The chain-stopping drive mechanism 23 is connected to the input end of the chain-locking mechanisms 22 and 25 through a transmission component to ensure stable power transmission.

[0029] like Figure 3 and Figure 4As shown, the chain clamping mechanism 25 has the same structure as the chain clamping mechanism 22 and is symmetrically arranged to ensure uniform clamping force on the anchor chain. The chain clamping mechanism 22 includes a connecting seat 221 for fixed support, a chain clamping arm 222 for clamping the anchor chain, a limiting block 223 for limiting the rotation stroke, a connecting seat 224 for auxiliary support, a fixing sleeve 225 for fixing the connecting shaft, a connecting shaft 226 for transmitting power, a key 227 for preventing relative rotation between the shaft and the arm, a chain clamping groove 228 for fitting the anchor chain, and a limiting seat 229 for cooperating with the limiting block. The bottom of the connecting seat 221 is parallel to the bottom of the connecting seat 224 and is fixedly connected to both ends of the top surface of the base 21 by welding. There are two fixing sleeves 225, which are made of wear-resistant alloy material. The two fixing sleeves 225 are fixed externally by interference fit. The connecting shaft 226 is connected to the center of the connecting seat 221 and the connecting seat 224. The two sides of the connecting shaft 226 are movably connected to the corresponding fixed sleeves 225. One side of the connecting shaft 226 is connected to the chain stop drive mechanism 23. The lower side of the chain locking arm 222 is located between the connecting seat 221 and the connecting seat 224. Its lower side is circumferentially fixed to the outside of the connecting shaft 226 by a key 227. The upper side of the chain locking arm 222 has an arc-shaped chain locking groove 228 that matches the size of the anchor chain to improve the locking stability. The limiting seat 229 is vertically welded to the center of the top surface of the base 21 and is located below the chain locking arm 222. The limiting block 223 is fixedly connected to the bottom of the chain locking arm 222 by welding and is located outside the limiting seat 229. The two work together to precisely limit the rotation angle of the chain locking arm 222.

[0030] like Figure 5 and Figure 6As shown, the chain stop drive mechanism 23 includes a mounting sleeve 231 connecting to the first chain clamping mechanism, a fixing screw 232 fixing the mounting sleeve, a connecting block 233 for transmitting power, a connecting rod 234 for synchronous transmission, a mounting sleeve 235 connecting to the second chain clamping mechanism, a fixing screw 236 fixing the second mounting sleeve, a connecting head 237 for hinged connection, a connecting block 238 for transferring power, a connecting head 239 for connecting the hydraulic cylinder, a hydraulic cylinder 2310 for providing driving force, a connecting head 2311 connecting to the first mounting sleeve, and a connecting block 2312 fixing the third connecting head. The mounting sleeve 231 is tightly fixed to the input end (end of the connecting shaft 226) of the first chain clamping mechanism 22 by several fixing screws 232 made of internal hexagonal material. The lower and upper sides of the mounting sleeve 231 are respectively welded with connecting blocks 233 and 2312, and the two... All components are provided with hinge holes; the mounting sleeve 235 is fixedly connected to the input end (corresponding to the end of the connecting shaft) of the chain mechanism 25 by several hexagonal screws 236; a connecting block 238 with hinge holes is welded to the upper side of the mounting sleeve 235; both ends of the connecting rod 234 are welded with connectors 237, one connector 237 is hinged to the lower side of the connecting block 233 by a pin, and the other connector 237 is hinged to the left side of the connecting block 238 by a pin, ensuring synchronous power transmission; a connector 239 is welded to the piston rod end on one side of the cylinder 2310 and is hinged to the upper side of the connecting block 238 by a pin, and a connector 311 is welded to the other end of the cylinder 2310 and is hinged to the upper side of the connecting block 312 by a pin, so that the chain mechanism can be precisely controlled by the extension and retraction of the cylinder.

[0031] Both fixing screw 232 and fixing screw 236 are internal hexagon screws, which facilitates operation and installation in confined spaces.

[0032] like Figure 7 and Figure 8 As shown, the chain guide mechanism 4 includes a clamping plate 41 for fixing the fixed shaft, three fixing screws 42 for fastening the clamping plate, a clamping groove 43 for clamping position, a fixed shaft 44 for supporting the chain guide wheel, and a chain guide wheel 45 for guiding the anchor chain. The fixed shaft 44 is movably connected to the lower interior of the mounting groove 3 via a sliding bearing, and its position can be finely adjusted along the groove. Several evenly distributed clamping grooves 43 are provided on both sides of the fixed shaft 44. The chain guide wheel 45 is made of high-strength alloy and is located inside the mounting groove 3. Its central interior is movably connected to the outside of the fixed shaft 44 via a bearing, and it can be guided as the anchor chain rotates. There are several clamping plates 41, each of which is fixedly connected to the outside of both sides of the mounting groove 3 via several hexagonal fixing screws 42. The inner sides of the clamping plates 41 are respectively embedded in the inner sides of the corresponding clamping grooves 43 to lock the position of the fixed shaft 44.

[0033] Among them, the fixing screw 342 is a hexagonal screw, which is easy to install and remove using a common wrench; both sides of the upper side of the mounting groove 3 are fixedly connected with guardrails by welding. The guardrails are made of round steel and are 1.2 meters high, which can effectively prevent people from falling and debris from entering.

[0034] The invention is used in the following ways: The invention has a reasonable and simple structure, low production cost, convenient installation, and complete functions. The platform 1 serves as the basic carrier, and the mounting groove 3 on its outer side provides installation space for the entire chain stop system. The guardrails fixedly connected to the upper two sides of the mounting groove 3 are always intact, which can effectively prevent personnel from accidentally falling in or debris from entering the groove during offshore operations, thus ensuring the safety of equipment and personnel. The chain stop device 2 is fixedly connected to the inner side of the top surface of the mounting groove 3 through the bottom of the base 21, and is stably located at the top of the opening of the mounting groove 3. The outer shell 24 completely encloses the chain locking mechanism 1 22 and the chain locking mechanism 25 to prevent seawater and sea wind from corroding the internal components. The chain guide mechanism 4 is movably connected to the lower side of the mounting slot 3, providing guiding support for chain transmission. The entire device maintains a stable installation posture in the sea environment without significant shaking or displacement. Here, the chain locking mechanism 25 and the chain locking mechanism 1 22 have the same structure and are symmetrically arranged. They respond synchronously to the command of the chain stop drive mechanism 23 to lock and release the chain. During normal chain transmission and adjustment, the chain locking arm 222 in the chain locking mechanism 1 22 is in the open state. The connecting shaft 226 maintains a stable rotation posture through the fixing sleeve 225 (fixed in the center of the connecting seat 1 221 and the connecting seat 2 224 respectively). The chain is fixed to the outside of the connecting shaft 226 by key 227. At this time, the limiting block 223 (fixed to the bottom of the chain arm 222) is in contact with the limiting seat 229 (fixed to the center of the top surface of the base 21). The chain groove 228 on the upper side of the chain arm 222 is not in contact with the chain and does not affect the normal operation of the chain. When it is necessary to stop the chain, the connecting shaft 226 in the chain locking mechanism 1 22 and chain locking mechanism 25 rotates under the drive of the chain stop drive mechanism 23. The key 227 drives the chain arm 222 to rotate around the connecting shaft 226. The chain arm 222 gradually moves closer to the chain until the chain groove 228 is tightly fitted with the chain, thereby stopping the chain. The locking limit is used to restrict the excessive rotation of the chain locking arm 222 by the blocking effect of the limit seat 229, so as to avoid damage to the chain or chain locking arm 222 due to excessive locking force, and to ensure the safety and reliability of the chain stopping action. Here, the chain stopping drive mechanism 23 is a power output component, which drives the chain locking mechanism 1 22 and chain locking mechanism 25 through the cooperation of multiple components. The mounting sleeve 1 231 is firmly fixed to the input end of the chain locking mechanism 1 22 (outside the connecting shaft 226) by several internal hexagonal fixing screws 1 232. The connecting block 1 233 on the lower side of the mounting sleeve 1 231 is stably connected to the connecting block 3 2312 on the upper side.Mounting sleeve 235 is fixed to the input end of chain mechanism 25 (corresponding to the outside of the connecting shaft) by several hexagonal socket screws 236. Connecting block 238 on the upper side of mounting sleeve 235 is stable. When the chain mechanism needs to be driven, cylinder 2310 is activated as the power source. Connector 239 on one side of the piston rod of cylinder 2310 is hinged to the upper side of connecting block 238. When the piston rod extends or retracts, it drives connecting block 238 to rotate around mounting sleeve 235 via connector 239, thereby rotating the connecting shaft of chain mechanism 25. Simultaneously, connector 3211 on the other side of cylinder 2310 is hinged to the upper side of connecting block 3212, allowing cylinder 2310 to rotate as a whole. During operation, the connecting block 2312 drives the mounting sleeve 231 to rotate, which in turn drives the connecting shaft of the chain locking mechanism 22 to rotate. In addition, the connecting heads 237 at both ends of the connecting rod 234 are hinged to the lower side of the connecting block 233 and the left side of the connecting block 238, respectively. During the driving process of the hydraulic cylinder 2310, the connecting rod 234 can assist in transmitting power, ensuring that the actions of the chain locking mechanism 22 and the chain locking mechanism 25 are synchronized and opposite, thereby avoiding chain stop failure due to mismatch of actions on both sides. The entire power transmission process is smooth without jamming or abnormal noise, each hinge point rotates flexibly, and the fixing screws 232 and 236 are not loose, ensuring stable power transmission. The chain guide mechanism 4 always plays a guiding role during chain transmission. The fixed shaft 44 is movably connected to the lower interior of the mounting groove 3, and several slots 43 on its outer sides provide a basis for position adjustment. The guide sprocket 45 is movably connected to the outside of the fixed shaft 44 in the center. During chain transmission, the guide sprocket 45 rotates synchronously with the chain, reducing friction loss between the chain and the chain guide mechanism 4 through its own rotation, ensuring smooth chain transmission without jamming or deviation. During normal operation of the offshore floating power generation platform, the chain passes sequentially through the area between the guide sprocket 45 of the chain guide mechanism 4, the chain locking mechanism 1 22 and the chain locking mechanism 25 of the chain stop device 2. The guide sprocket 45 continuously guides the chain, ensuring a stable chain transmission path. The chain stop device 2 is in a standby state, and the chain locking mechanism 1 22... 2. The chain stop mechanism 25 remains open, not interfering with the normal operation of the chain. In case of emergency or when chain transmission needs to be paused, the control system issues a chain stop command. The hydraulic cylinder 2310 of the chain stop drive mechanism 23 quickly actuates, driving the connecting shafts of the chain stop mechanism 22 and the chain stop mechanism 25 to rotate through the mounting sleeve 231 and mounting sleeve 235 respectively. This causes the chain stop arm 222 to rotate synchronously, and the chain stop groove 228 quickly engages and locks the chain. The hydraulic cylinder 2310 then reverses its action, causing the chain stop mechanism 22 and the chain stop mechanism 25 to reset, and the chain resumes normal transmission. The entire chain stop system, through the coordinated action of its components, achieves efficient guidance and reliable stopping of the chain, meeting the needs of the adjustment operation of offshore floating power generation platforms.
