Description

Technical Field

[0001] This invention relates to the field of downwind anchor winches, specifically to a non-powered downwind anchor winch. Background Technology

[0002] The unpowered anchor winch is the core equipment of a ship's anchoring system. During the anchor chain lowering phase, it does not rely on external power sources such as motors or hydraulic systems. Instead, it drives the anchor chain to descend by the weight of the anchor chain itself or the gravitational potential energy generated by the ship's draft difference. With the help of a braking mechanism and guiding components, it can achieve precise control of the lowering speed. It is suitable for small and medium-sized ships and anchoring scenarios where energy consumption control is required.

[0003] Traditional downwind anchor winches typically rely on manual or simple mechanical braking to control the descent speed of the anchor chain. However, this control method makes it difficult to achieve a smooth and uniform descent process, easily leading to sudden changes in the descent speed of the anchor chain, accompanied by obvious jerking and impact phenomena. This not only significantly increases the difficulty of operation and safety risks, but also easily causes problems such as anchor chain accumulation, chain jumping, and brake failure, and may even cause equipment damage or personal injury. In addition, the instability of the descent process can also affect the accuracy of anchor positioning and system reliability, ultimately reducing the effectiveness of the downwind anchor winch.

[0013] The technical solution provided by this invention has the following advantages compared with the known prior art: I. This invention, by setting up components such as a centrifugal damping mechanism, uses a centrifugal ring fixedly connected to the descending anchor winch body and rotating synchronously. Under the action of centrifugal force, the counterweight ball drives the gravity rod to move outward, pushing the moving ring to slide and changing the hydraulic pressure. This causes the pushing ring to drive the friction ring to move closer to or away from the descending anchor winch body, achieving adaptive adjustment of friction force. Thus, this device can automatically and smoothly control the descending speed according to the anchor chain lowering speed without relying on external power, effectively avoiding sudden speed changes and impacts, and improving operational safety and anchor positioning accuracy.

[0014] II. This invention, by setting up rotating heat dissipation components and other parts, forms a circulating cooling circuit through the cooperation of these components and connection with the water supply tank. The contact block drives the rotating ring to rotate with the centrifugal ring, which in turn drives the coolant to circulate in the flow heat dissipation groove and the spiral heat dissipation groove. The heat absorption block absorbs the braking heat and transfers it to the coolant through the heat dissipation plate. Combined with the coordinated airflow heat dissipation of the airflow groove, the moving ring, the air outlet groove and the spiral air inlet groove, this invention achieves efficient heat dissipation during continuous braking, prevents performance degradation and damage caused by overheating of components, extends the service life of key components, and ensures the long-term stable operation of the anchor winch.

[0015] Third, this invention, by setting up a contact deceleration component, through the cooperation between various components and the transmission adjustment of the reducer and connecting gear, drives the internal transmission gear through the rotating ring to make the reverse ring rotate in the opposite direction. The deceleration block contacts the inclined block under the action of the spring to generate reverse friction. In conjunction with the reducer to adjust the speed, and the design of the inclined surface of the deceleration block and the smooth block reduces friction loss, thereby achieving the effect that this device can realize multi-stage smooth deceleration, significantly reduce the downward jerking feeling, improve speed control accuracy, reduce anchor chain impact and part wear, and further improve the reliability and safety of the anchoring process.

[0019] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0020] The present invention will be further described below with reference to embodiments.

[0021] See attached document Figure 1-8A non-powered descending anchor winch includes: a descending anchor winch body 1 and a support frame 2. The outer side of the descending anchor winch body 1 is rotatably connected to the support frame 2. It also includes: two sets of centrifugal damping mechanisms 3 for automatically adjusting friction according to the anchor chain lowering speed. Each centrifugal damping mechanism 3 includes a fixed column 31, with a centrifugal ring 32 disposed on the inner side of the fixed column 31 and fixedly connected to the outer side of the descending anchor winch body 1. A gravity rod 33 is hinged to the outer side of the centrifugal ring 32, and a counterweight ball is fixedly connected to the other end of the gravity rod 33. A movable ring 34 is disposed on the outer side of the gravity rod 33 and is connected to the fixed column 31. The internal sliding connection of column 31 and the elastic connection of movable ring 34 to fixed column 31 via spring (spring not shown in the figure) are as follows: the external connection of fixed column 31 is to hydraulic ring 35 via hose, and hydraulic ring 35 is located on the external side of fixed column 31; the internal sliding connection of hydraulic ring 35 is to push ring 36, and push ring 36 is elastically connected to hydraulic ring 35 via spring (spring not shown in the figure); the internal connection of push ring 36 is to friction ring 37 via fixed rod; the internal connection of friction ring 37 is to a rotating heat dissipation assembly 38, and the external connection of friction ring 37 is to a contact deceleration assembly 39. The descending anchor winch body 1 is rotatably connected to the support frame 2, providing a stable support foundation for the operation of the descending anchor winch body 1 and ensuring the stability of the equipment structure during the lowering of the anchor chain. Two sets of centrifugal damping mechanisms 3 serve as the core of speed control. The fixed columns 31 inside provide a regular mounting carrier for various parts, allowing for orderly arrangement and smooth operation. The centrifugal ring 32 is fixedly connected to the descending anchor winch body 1 and can rotate synchronously with it. The gravity rod 33, hinged to the outside of the centrifugal ring 32, has a counterweight ball at its end that, using centrifugal force, extends the gravity rod 33 towards the edge as the anchor winch rotates, and then pushes the moving ring 34 to slide smoothly within the fixed column 31 via the L-shaped rod 4. The sliding of the moving ring 34 changes the internal space of the fixed column 31, and the pressure is transmitted to the hydraulic ring 35 through a hose. The internal pushing ring 36 slides under pressure, and then drives the friction ring 37 to flexibly approach the descending anchor winch body 1 through the fixed rod, thereby adjusting the friction force; the rotating heat dissipation component 38 can dissipate the large amount of heat generated during braking in time, avoiding high temperature from causing component performance degradation or braking failure, and effectively extending the service life of the equipment; the contact deceleration component 39 further enhances the braking effect, keeping the anchor chain lowering speed always precise and controllable; the overall structure, through the ingenious combination of centrifugal force and hydraulic transmission, can adaptively adjust the anchor chain lowering speed without relying on external power, which not only completely solves the problem of inconsistent speed and jerking impact of traditional anchor winches, but also greatly reduces the difficulty of operation and safety risks, effectively avoids anchor chain accumulation, chain jumping and other faults, significantly improves the accuracy of anchor positioning and the reliability of system operation, and ensures a smooth and efficient anchoring process; The gravity rod 33 has an L-shaped rod 4 on its outer side, and the L-shaped rod 4 is rotatably connected to a connecting ring, which is fixedly connected to the centrifugal ring 32. The L-shaped rod 4 works in conjunction with the counterweight ball, and the L-shaped rod 4 is rotatably connected to the connecting ring fixed on the centrifugal ring 32. When the centrifugal ring 32 rotates with the anchor hoist body, it will drive the connecting ring to rotate synchronously, thereby driving the L-shaped rod 4 and the gravity rod 33 to rotate synchronously. Under the centrifugal force generated by the rotation, the counterweight ball will push the short rod of the L-shaped rod 4, so that the long rod of the L-shaped rod 4 will generate amplified thrust by means of the lever principle, allowing the L-shaped rod 4 to push the moving ring 34 more efficiently and smoothly. This structural design avoids the problem of uneven force or jamming during the pushing process, ensuring accurate and sufficient thrust transmission, and providing a stable foundation for the subsequent pressure adjustment of the hydraulic system. See attached document Figure 1-8 The rotating heat dissipation assembly 38 is used to efficiently dissipate heat generated during braking and prevent overheating of components. It includes a contact block 381, a rotating ring 382 slidably connected to the outer side of the contact block 381, and the rotating ring 382 rotatably connected to a friction ring 37. The rotating ring 382 and the contact block 381 are elastically connected by a spring. Several sets of push blades 383 are rotatably connected to the inner side of the rotating ring 382 via a torsion spring. The friction ring 37 has flow cooling grooves inside, and the interior of the flow cooling grooves slides smoothly against the push blades 383. The flow cooling channel is connected to a spiral cooling channel at one end. An inclined plate 384 is provided on the outer side of the water inlet end of the spiral cooling channel, and the inclined plate 384 is fixedly connected to the flow cooling channel. A receiving groove is provided on one side of the pusher blade 383, and the receiving groove is opened on the inner side of the rotating ring 382. A heat dissipation plate 385 is fixedly connected to the side of the flow cooling channel and the spiral cooling channel near the centrifugal ring 32, and a heat absorption block 386 is fixedly connected to the inner side of the heat dissipation plate 385, and the heat absorption block 386 is fixedly connected to the friction ring 37. In this device, the contact block 381 of the rotating heat dissipation assembly 38 is slidably connected to the inner side of the rotating ring 382 and elastically connected by a spring. During operation, the contact block 381 first contacts the centrifugal ring 32. Under the rotational force of the centrifugal ring 32, the outer rotating ring 382 rotates smoothly on the surface of the friction ring 37. The pushing blade 383 is connected to the rotating ring 382 via a torsion spring. When the rotating ring 382 rotates, the pushing blade 383 rotates synchronously, generating thrust that drives the coolant in the flow heat dissipation channel to flow rapidly. The flow heat dissipation channel and the spiral heat dissipation channel are interconnected, allowing the coolant to flow smoothly into the spiral heat dissipation channel. The spiral structure effectively extends the flow path of the coolant, significantly improving heat dissipation efficiency. The inclined plate 384 fixed to the outer side of the water inlet guides the coolant... The sequential flow avoids stagnation. The receiving groove opened on the inner side of the rotating ring 382 allows the pusher blade 383 to be received and smoothly passed through when it rotates to the side of the inclined plate 384, ensuring uninterrupted coolant circulation. The heat dissipation plate 385, which is fixed to the side of the flow heat dissipation groove and the spiral heat dissipation groove near the anchor machine body, has a heat absorption block 386 on its inner side that is tightly fixed to the friction ring 37. It can quickly absorb a large amount of heat generated by braking and transfer it to the coolant, achieving efficient and rapid heat dissipation. This component completely solves the problem of high temperature heating of parts during braking, avoids the aging and deformation of parts and the decline of braking performance caused by high temperature, extends the service life of the core components of the equipment, and ensures that the anchor machine can maintain stable performance under long-term high-intensity operation. One side of the flowing heat dissipation trough is connected to the water supply tank 5 via a hose, and the drain end of the spiral heat dissipation trough is connected to the water supply tank 5 via a hose. The flow heat dissipation trough is connected to the water supply tank 5 via a hose, which can continuously replenish the cooling system with coolant and ensure sufficient cooling medium. The water supply tank 5 can be flexibly arranged in a suitable position to stably deliver the cooling medium to the flowing heat dissipation trough (it can also be equipped with a water pump of existing technology to assist in delivery according to the usage requirements). Under the thrust of the pusher blade 383, the cooling medium flows back into the water supply tank 5, thus forming a complete coolant circulation loop, allowing the coolant to be reused. This saves resources and achieves continuous heat dissipation. This circulation structure not only improves the heat dissipation efficiency, but also ensures that the coolant circulates smoothly without stagnation, avoids interruption in the heat dissipation process, effectively controls the temperature of the friction ring 37 and surrounding parts, prevents equipment failure caused by local overheating from the root, and further ensures the continuous and stable operation of the anchor winch. The friction ring 37 has an airflow groove 6 on its inner side and a movable ring 7 on its outer side. The movable ring 7 is rotatably connected to the friction ring 37 and fixedly connected to the rotating ring 382. The airflow groove 6 on the inner side of the friction ring 37 provides a smooth channel for airflow. The airflow groove 6 can be adaptively adjusted according to actual usage needs to enhance its performance. The movable ring 7 on the outer side is rotatably connected to the friction ring 37 and firmly fixed to the rotating ring 382. It can rotate synchronously with the rotating ring 382. The rotation of the movable ring 7 generates airflow to accelerate the air circulation on the surface of the friction ring 37. It can directionally guide the airflow in the airflow groove 6, efficiently assisting the heat sink 385 in dissipating heat. This not only further improves the overall heat dissipation effect but also avoids local heat accumulation on the surface of the friction ring 37, making the temperature distribution more uniform and ensuring the stable operation of the heat dissipation system. See attached document Figure 1-8 The contact deceleration assembly 39 is used to achieve smooth deceleration. It includes a reversing ring 391, a number of deceleration blocks 392 are slidably connected to the inner side of the reversing ring 391, and the deceleration blocks 392 are elastically connected to the reversing ring 391 through springs. A fixed ring 393 is provided on the inner side of the reversing ring 391, and an inclined block 394 is fixedly connected inside the fixed ring 393. The fixed ring 393 is fixedly connected to the centrifugal ring 32. A driven internal gear 395 is fixedly connected to the inner side of the reversing ring 391. A driven gear 396 is rotatably connected to the inner side of the driven internal gear 395, and a support ring is rotatably connected to the outer side of the driven gear 396. A transmission gear 397 is provided on the outer side of the driven gear 396, and the transmission gear 397 is rotatably connected to the support ring. A transmission internal gear 398 meshes with the top of the transmission gear 397, and the transmission internal gear 398 is fixedly connected to the rotating ring 382. In this assembly, several sets of speed reduction blocks 392 are slidably connected to the inner side of the reversing ring 391 of the contact deceleration component 39. The speed reduction blocks 392 are elastically connected to the reversing ring 391 through springs, and the fixed ring 393 is fixed to the centrifugal ring 32. The fixed ring 393 provides stable support for the tilting block 394 to ensure that its position does not shift. The tilting block 394 rotates synchronously with the anchor winch. The reversing ring 391 and its connecting parts can rotate with the rotating ring 382. The driven internal gear 395 and the driven gear 396 on the inner side of the reversing ring 391 mesh with each other. The driven gear 396 obtains stable rotational support through the support ring. The transmission gear 397 on its outer side is rotatably connected to the support ring and meshes with the transmission internal gear 398. The transmission internal gear 398 is fixedly connected to the rotating ring 382. Together with the reducer 8 and the connecting gear 9, it forms a complete and efficient transmission link. When the rotating ring 382 rotates... When in motion, the internal transmission gear 398 drives the transmission gear 397 to rotate, which in turn drives the driven gear 396 and the driven internal gear 395 to rotate, ultimately achieving the reverse rotation of the reversing ring 391. This causes the deceleration block 392 and the inclined block 394 to generate reverse friction, significantly enhancing the deceleration effect. When the reversing ring 391 rotates, the deceleration block 392 will contact the inclined block 394, achieving initial deceleration through friction between the two. After being subjected to the force of the inclined block 394, the deceleration block 392 will slide into the interior of the reversing ring 391. This further optimizes the deceleration effect, making the anchor chain lowering speed more stable, solving the problem of strong braking jerking in traditional systems, improving the accuracy of speed control, and at the same time, the reverse rotation design can effectively buffer the impact during the operation of the anchor winch, avoid anchor chain pulling and damage to equipment parts, reduce the failure rate, and ensure the safety and reliability of the anchoring process. Among them, a reducer 8 is fixedly connected to the outer side of the driven gear 396, and a connecting gear 9 is fixedly connected to the outer side of the reducer 8, and the connecting gear 9 meshes with the transmission gear 397; the reducer 8 on the outer side of the driven gear 396 and the connecting gear 9 on one side cooperate with each other, and the connecting gear 9 meshes tightly with the transmission gear 397, which not only ensures stable power transmission between the reducer 8 and the transmission gear 397, but also precisely reduces the speed of the driven gear 396 through the reducer 8, making the overall power transmission smoother; one side of the reduction block 392 is inclined, and a smooth block 10 is fixedly connected to one side of the reduction block 392; The deceleration block 392 is designed with an inclined side, which allows it to form a smooth fit and guide when it contacts the inclined block 394 inside the fixed ring 393. This effectively reduces the impact and jamming at the moment of contact, avoids deceleration jerks caused by uneven force, and allows the entire deceleration process to transition smoothly. The optical slider 10 fixed on one side of the deceleration block 392 can further reduce the frictional resistance between it and the inclined block 394, reduce the wear and tear of both, significantly extend the service life of the contact deceleration component 39, and avoid the problem of component jamming or sudden braking effect caused by excessive friction, ensuring the continuity and accuracy of anchor chain lowering speed control. It is worth noting that all gas and liquid flow path connections in this technical solution are sealed using a sealing structure to prevent leakage, forming a reliable dynamic or static sealing system. This effectively eliminates leakage and ensures the pressure stability and energy transmission efficiency of the hydraulic system. It is also worth noting that the specific selection of springs and other elastic elements and key components involved in this technical solution is adapted according to actual working conditions (such as pressure, frequency, load, etc.) to meet the performance requirements for long-term stable operation of the equipment (and can be replaced accordingly based on actual application needs). Furthermore, some springs (not shown in the figure), along with the sliding and movement of each moving part, are achieved through reasonable limiting and guiding structures in existing technologies (not fully shown in the figure) to ensure coordinated function and reliable operation of each mechanism. In addition, conventional protective or additional limiting structures can be added to relevant components according to specific usage environments and requirements.

[0022] Working principle: During operation, the anchor chain drives the downward anchor winch body 1 to rotate under its own weight. The downward anchor winch body 1 and the support frame 2 maintain a stable rotational connection, providing solid support for the overall operation. The centrifugal ring 32, which is fixedly connected to the downward anchor winch body 1, rotates synchronously with the downward anchor winch body 1. The gravity rod 33, which is hinged to the outside of the centrifugal ring 32, drives the counterweight ball to extend outward under the centrifugal force generated by the rotation. The L-shaped rod 4 on the outside of the gravity rod 33 and the rotating ring 382 fixed to the centrifugal ring 32 rotate together, and the moving ring 34 is pushed by the lever principle on the fixed column 3. The sliding ring 34 changes the internal pressure of the fixed column 31, which is transmitted to the hydraulic ring 35 through the hose. This causes the push ring 36 inside the hydraulic ring 35 to slide under pressure and drive the friction ring 37 to gradually approach the descending anchor body 1 through the fixed rod, initially forming friction to regulate the descending speed. At the same time, the contact block 381 contacts the centrifugal ring 32. Under the rotational force of the centrifugal ring 32, the contact block 381 is driven and pulls the rotating ring 382 fixed to it on the outside, so that the rotating ring 382 rotates smoothly on the surface of the friction ring 37. After the rotating ring 382 rotates, it synchronously drives the two core components to operate within the contact reduction assembly 39. The rotating ring 382 drives the fixed transmission internal gear 398 to rotate synchronously. The transmission internal gear 398 meshes with the transmission gear 397, thereby driving the transmission gear 397 to operate. The transmission gear 397 transmits power precisely through the connecting gear 9 and the reducer 8 outside the driven gear 396. The reducer 8 effectively reduces the speed to avoid excessive wear of components. Subsequently, the driven gear 396 and the driven internal gear 397 inside the reversing ring 391... 5. Engagement ultimately drives the reverse ring 391 to rotate in the opposite direction; while the fixed ring 393, which is fixedly connected to the centrifugal ring 32, and the inclined block 394 inside it always rotate synchronously with the anchor machine body in the forward direction. The deceleration blocks 392 arranged in a gradient on the inner side of the reverse ring 391 contact the forward rotating inclined block 394 under the action of spring elasticity, generating reverse friction force to form the core deceleration effect. At the same time, the inclined design of the deceleration block 392 and the surface fixed smooth slider 10 greatly reduce the impact and friction loss at the moment of contact, making the deceleration process smooth and without jerking. Simultaneously, the rotation of the rotating ring 382 drives the rotating heat dissipation assembly 38 to move; the pusher blade 383 connected to the inner side of the rotating ring 382 by the torsion spring rotates synchronously with the rotating ring 382 to generate thrust, driving the coolant in the flow heat dissipation channel to flow. The flow heat dissipation channel is connected to the water supply tank 5 through the hose to form a complete circulation loop. Under the thrust of the pusher blade 383, the coolant flows into the spiral heat dissipation channel through the flow heat dissipation channel. The spiral structure greatly extends the heat dissipation path of the coolant. The inclined plate 384 at the water inlet end of the flow heat dissipation channel guides the coolant to flow in an orderly manner to avoid stagnation. When the pusher blade 383 rotates to one side of the inclined plate 384, it will be stored in the storage groove inside the rotating ring 382 to ensure that the coolant circulation is uninterrupted. The heat dissipation plate 385 and the heat absorption block 386 fixed to the friction ring 37 on the inner side quickly absorb the large amount of heat generated by the friction ring 37 and surrounding components during braking and transfer it to the coolant to achieve efficient liquid cooling heat dissipation. In addition, the rotating ring 382 also drives the movable ring 7 fixed thereto to rotate synchronously on the outside of the friction ring 37. With the cooperation of the rotation of the movable ring 7, the external air is actively guided to accelerate inflow. After the airflow enters the airflow channel 6, it is discharged through the movable ring 7 via stable transmission. This not only assists in the heat dissipation of the heat sink 385 and accelerates the air circulation, but also provides air cooling for the contact deceleration component 39, preventing the components from degrading due to high temperature. The entire operation process does not rely on external power. Starting from the contact between the contact block 381 and the centrifugal ring 32, the adaptive and precise control of the anchor chain lowering speed is achieved through the synergistic effect of centrifugal force hydraulic transmission and mechanical transmission. The heat dissipation system ensures the long-term stable operation of the equipment and effectively avoids problems such as anchor chain accumulation, chain jumping and brake failure.
