Description

Technical Field

[0001] This invention relates to the field of ship anchoring technology, and more specifically, to an anchoring device for marine vessels. Background Technology

[0002] After a ship docks in port, it will drop an anchor into the seabed to prevent it from drifting away. The anchor hooks onto the seabed soil to position the ship, and the anchoring device is used to drop and retrieve the anchor.

[0003] When a ship is anchored at sea, the surging currents on the seabed cause the anchor chain to rotate as it is pulled up, resulting in the chain becoming taut. This means that when the anchor chain is wound up after anchoring, it remains taut. This tautness creates additional torsional stress within the chain, and prolonged or excessive tightening can lead to stress concentration, affecting the overall strength of the anchor chain. Furthermore, winding the chain while taut can cause localized deformation, reducing its load-bearing capacity and service life. Additionally, the stress under taut conditions can lead to sudden failure due to stress superposition, increasing the risk of breakage or slippage. Therefore, ensuring that the anchor chain remains in a naturally slack state during anchoring is a critical technical challenge that urgently needs to be addressed. Summary of the Invention

[0004] This invention provides an anchor-raising device for marine vessels, which solves the technical problem in related technologies that the anchor chain is easily damaged, its service life is reduced, or even safety hazards may occur when the anchor chain is in a tightened state during anchor raising.

[0005] The present invention provides an anchor-lifting device for marine vessels, including a frame and roller units and an anchor-lifting unit disposed on both sides of the frame, wherein an anchor chain is passed between the roller units and the anchor-lifting unit, and an anchor head is fixedly connected to one end of the anchor chain. A speed regulating unit is provided at the upper end of the frame, and a processing component fixed on the ship deck on one side of the frame for changing the tightened anchor chain to a slack state. The processing component includes a tube fixed to the ship's deck, and an adjustment seat is fixedly connected inside the tube. The adjustment seat has a perforation in the middle, and the bottom of the adjustment seat is a dome-shaped surface with ball bearings movably embedded therein. An expansion mask is fixedly connected to the bottom of the tube.

[0006] As a further optimization of the present invention, the anchoring unit includes a rotating shaft rotatably connected to the frame, and a rotating wheel and a limiting disc are fixedly connected to the surface of the rotating shaft. The anchor chain is wound around the surface of the limiting disc and is clamped and limited by the limiting disc.

[0007] As a further optimization of the present invention, the speed regulating unit includes a speed regulating box fixedly connected to the frame, the rotating wheel is located inside the speed regulating box, a speed regulating ring is movably connected to the ring side of the speed regulating box, and a speed regulating seat is fixedly connected to the outside of the speed regulating ring, and a speed regulating rod is threadedly connected to the inside of the speed regulating seat.

[0008] As a further optimization of the present invention, the tube body is provided with a cleaning component, the cleaning component includes a first cleaning brush fixedly connected to the inner wall of the expansion mask, a striking ball fixedly connected to the inner wall of the tube body by a spring rod, and the striking ball has a solid ball inside, a second cleaning brush fixedly connected to the inner wall of the tube body, and a rinsing tube fixedly connected to the upper part of the tube body.

[0009] As a further optimization of the present invention, a drying component is provided on the inner side of the limiting plate. The drying component includes an air bladder fixedly connected to the inner side of the limiting plate, and the air bladder is wrapped with absorbent cotton. Absorbent rollers are arranged in a ring array on the circumferential side of the limiting plate, and the absorbent rollers are arranged in pairs. The absorbent rollers are composed of a sponge wrapped with a metal rod.

[0010] As a further optimization of the present invention, the limiting plate is a hollow structure and is connected to the airbag. The surface of the airbag is provided with an air inlet. One-way valves are provided at the connection between the limiting plate and the airbag and inside the air inlet. The surface of the limiting plate is provided with jet holes.

[0011] As a further optimization of the present invention, an elastic clamping block is slidably sleeved on the outside of two adjacent water-absorbing rollers, and a spring is fixedly connected between the elastic clamping block and the limiting plate. The elastic force of the spring is greater than the resistance of the elastic clamping block when it slides on the surface of the water-absorbing roller.

[0012] As a further optimization of the present invention, the limiting plate is provided with an anti-fall component. The anti-fall component includes an extension seat fixedly connected to one end of two adjacent water suction rollers, and the extension seat extends through the interior of the limiting plate and is slidably connected thereto. The limiting plate is provided with a counterweight ball. The frictional resistance between the extension seat and the limiting plate is greater than the thrust applied by the water suction roller to the extension seat.

[0013] The beneficial effects of this invention are as follows: 1. The anchor-raising device for marine vessels described in this invention guides the anchor chain into the tube body through the expansion mask, and guides it into the perforation through the arc-shaped surface at the bottom of the adjusting seat. The perforation has a cross structure, which restricts the anchor chain as it passes through the perforation, causing two adjacent elliptical rings on the anchor chain to move in a cross-shaped state. This loosens the taut anchor chain, allowing it to be wound around in a naturally relaxed state, thus improving the service life of the anchor chain, reducing the risk of anchor chain breakage, and ensuring the safety of anchor raising.

[0014] 2. The anchor-lifting device for marine vessels described in this invention uses a first cleaning brush to clean weeds and other attachments on the surface of the anchor chain. Simultaneously, under the action of the adjusting seat, the anchor chain rotates when it changes from a tightened state to a loose state during movement. This rotation of the anchor chain enhances the cleaning effect of the first cleaning brush on the anchor chain surface.

[0015] 3. The anchor-lifting device for marine vessels described in this invention can remove stubborn deposits such as barnacles that are difficult to remove with a cleaning brush by impacting the anchor chain with a striking ball, thereby further improving the cleaning effect on the anchor chain. At the same time, the striking ball adopts a hollow structure and places a solid ball inside it. The presence of the solid ball inside will significantly increase the momentum during the impact and induce internal motion, resulting in a more concentrated transfer of energy to the impacted object, thereby improving the removal effect of stubborn deposits such as barnacles.

[0016] 4. The anchor-lifting device for marine vessels described in this invention uses absorbent cotton and absorbent rollers to absorb water stains on the surface of the anchor chain, accelerating the drying of the anchor chain surface, preventing water stains from causing anchor chain corrosion, and improving the service life of the anchor chain. Furthermore, the absorbent rollers are squeezed when the elastic clamps are reset, thereby squeezing out the water absorbed by the absorbent rollers, so that the absorbent rollers are always in an unsaturated state, ensuring their effectiveness in absorbing water stains on the surface of the anchor chain.

[0017] 5. The anchor-raising device for marine vessels described in this invention uses a water-absorbing roller to lock inside the anchor chain, thereby preventing the limiting disc from rotating and thus preventing the anchor chain from continuing to fall, improving safety during the anchor-raising process.

[0020] The subject matter described herein will now be discussed with reference to exemplary embodiments. It should be understood that these embodiments are discussed only to enable those skilled in the art to better understand and implement the subject matter described herein, and changes may be made to the function and arrangement of the elements discussed without departing from the scope of this specification. Various processes or components may be omitted, substituted, or added as needed in the examples. Furthermore, features described in some examples may be combined in other examples.

[0021] like Figures 1 to 4 As shown in the embodiment of the present invention, an anchor-lifting device for marine vessels includes a frame 10 and roller units 11 and anchor-lifting units 12 disposed on both sides of the frame 10. An anchor chain 15 is passed between the roller units 11 and the anchor-lifting units 12. An anchor head 16 is fixedly connected to one end of the anchor chain 15. A speed regulating unit 13 is provided at the upper end of the frame 10. A processing component 14 fixed on the ship deck is provided on one side of the frame 10 for changing the tightened anchor chain 15 to a slack state. The processing component 14 includes a tube 141 fixed on the ship deck, and an adjustment seat 143 is fixedly connected inside the tube 141. A through hole 144 is provided in the middle of the adjustment seat 143. The bottom of the adjustment seat 143 is a flat surface, and a ball bearing 145 is movably embedded in the flat surface. An expansion mask 142 is fixedly connected to the bottom of the tube 141. The anchoring unit 12 includes a rotating shaft 121 rotatably connected to the frame 10, and a rotating wheel 122 and a limiting plate 123 are fixedly connected to the surface of the rotating shaft 121. The anchor chain 15 is wound around the surface of the limiting plate 123 and is clamped and limited by the limiting plate 123. The speed control unit 13 includes a speed control box 131 fixedly connected to the frame 10. The rotating wheel 122 is located inside the speed control box 131. A speed control ring 132 is movably connected to the ring side of the speed control box 131, and a speed control seat 133 is fixedly connected to the outside of the speed control ring 132. A speed control rod 134 is threadedly connected to the inside of the speed control seat 133. During the anchoring process, the diameter of the speed control ring 132 can be adjusted by rotating the speed control rod 134, thereby changing the friction between the speed control ring 132 and the rotating wheel 122, and thus changing the rotation speed of the rotating wheel 122 during anchoring, i.e., changing the anchoring speed.

[0022] It should be noted that when anchoring, the drive device drives the rotating shaft 121 to rotate. The rotation of the rotating shaft 121 drives the limiting plate 123 and the rotating wheel 122 to rotate synchronously. When the limiting plate 123 rotates, it pulls the anchor chain 15, thereby pulling the anchor chain 15 out of the water. The pulled-out anchor chain 15 is then transported to the chain cavity and wound up. During the transport of the anchor chain 15, the anchor chain 15 slides along the surface of the idler roller unit 11, thereby reducing the friction between the anchor chain 15 and the ship and reducing the wear on the anchor chain 15. Since the anchor chain 15 is composed of multiple interlocking elliptical rings, adjacent elliptical rings form a cross shape when relaxed and drooping. During anchoring, the anchor chain 15 is guided into the tube 141 by the expanding mask 142 and then guided into the perforation 144 by the arc-shaped surface at the bottom of the adjusting seat 143. The perforation 144 has a cross structure, which restricts the anchor chain 15 as it passes through it. This causes adjacent elliptical rings on the anchor chain 15 to move in a cross shape, thereby loosening the taut anchor chain 15. The anchor chain 15 is then wound around in a naturally relaxed state, improving its service life, reducing the risk of breakage, and ensuring the safety of anchoring.

[0023] like Figure 1 and Figure 2 As shown, the tube body 141 is provided with a cleaning component 17 inside. The cleaning component 17 includes a first cleaning brush 171 fixedly connected to the inner wall of the expansion mask 142. The inner wall of the tube body 141 is fixedly connected to a striking ball 174 by a spring rod 173, and the striking ball 174 has a solid ball 175 inside. The inner wall of the tube body 141 is fixedly connected to a second cleaning brush 172, and the upper part of the tube body 141 is fixedly connected to a rinsing tube 176.

[0024] It should be noted that when the anchor chain 15 enters the expansion mask 142, the first cleaning brush 171 cleans the surface of the anchor chain 15 of weeds and other attached substances. Simultaneously, under the action of the adjusting seat 143, the anchor chain 15 rotates as it moves from a tightened state to a relaxed state. This rotation of the anchor chain 15 enhances the cleaning effect of the first cleaning brush 171 on the surface of the anchor chain 15. Furthermore, the rotation of the anchor chain 15 actuates the spring rod 173, causing it to bend and deform until it separates from the anchor chain 15. At this point, under the elastic force, the spring rod 173 swings, causing the striking ball 174 on the spring rod 173 to strike the surface of the anchor chain 15 after being cleaned by the first cleaning brush 171. The impact of the striking ball 174 removes substances such as barnacles from the surface of the anchor chain 15. Stubborn deposits that are difficult to remove with a cleaning brush are further cleaned, thus improving the cleaning effect on the anchor chain 15. At the same time, the striking ball 174 has a hollow structure with a solid ball 175 inside. The presence of the solid ball 175 inside significantly increases the momentum during impact and can induce internal motion, causing energy to be transferred more concentratedly to the impacted object, thereby improving the removal effect on stubborn deposits such as barnacles. Then, as the anchor chain 15 continues to move, the second cleaning brush 172 inside the tube 141 cleans the surface of the anchor chain 15 a second time, and works in conjunction with the high-pressure water jet flushing of the surface of the anchor chain 15 by the flushing pipe 176 at the top of the tube 141, further improving the cleaning effect on the surface of the anchor chain 15. The cleaning reduces the corrosion of the anchor chain 15 by deposits and also reduces the wear caused by deposits during the winding of the anchor chain 15, ensuring the smooth winding process of the anchor chain 15.

[0025] like Figures 5 to 6 As shown, a drying component 18 is provided on the inner side of the limiting disk 123. The drying component 18 includes an airbag 181 fixedly connected to the inner side of the limiting disk 123, and the airbag 181 is wrapped with absorbent cotton 182. Absorbent rollers 183 are arranged in a ring array on the circumferential side of the limiting disk 123, and the absorbent rollers 183 are arranged in pairs. The absorbent rollers 183 are composed of a sponge wrapped with a metal rod. The limiting plate 123 is a hollow structure and is connected to the airbag 181. The surface of the airbag 181 is provided with an air inlet. One-way valves are provided at the connection between the limiting plate 123 and the airbag 181 and inside the air inlet. The surface of the limiting plate 123 is provided with a jet hole 184. Two adjacent water-absorbing rollers 183 are slidably sleeved with elastic clamping blocks 185 on their outer sides, and a spring 186 is fixedly connected between the elastic clamping blocks 185 and the limiting plate 123. The elastic force of the spring 186 is greater than the resistance of the elastic clamping blocks 185 when sliding on the surface of the water-absorbing rollers 183.

[0026] It should be noted that after the anchor chain 15 is cleaned by the cleaning component 17, it reaches the position of the limiting plate 123. At this time, the anchor chain 15 will be inserted into the recess on the ring side of the limiting plate 123. During this process, the anchor chain 15 will squeeze the air bag 181, causing the air bag 181 to deform. After the air bag 181 deforms, it carries the water-absorbing cotton 182 to wrap the outside of the anchor chain 15. At the same time, the water-absorbing roller 183 on the limiting plate 123 is also inserted into the hole of the elliptical ring on the anchor chain 15. The water-absorbing cotton 182 and the water-absorbing roller 183 absorb the water stains on the surface of the anchor chain 15, accelerate the drying of the surface of the anchor chain 15, avoid water stains remaining and causing the anchor chain 15 to rust, and improve the service life of the anchor chain 15. It should be noted that as the limiting disc 123 rotates, when the water-absorbing roller 183 is inserted into the anchor chain 15, the elastic clamping block 185 on the surface of the water-absorbing roller 183 will be pushed towards the center of the limiting disc 123 by the pressure of the anchor chain 15. As the limiting disc 123 continues to rotate, after the water-absorbing roller 183 is disengaged from the anchor chain 15, it will push the elastic clamping block 185 to reset under the action of the spring 186. When the elastic clamping block 185 resets, it will squeeze the water-absorbing roller 183, thereby squeezing out the water absorbed by the water-absorbing roller 183, so that the water-absorbing roller 183 is always in an unsaturated state, ensuring its adsorption effect on water stains on the surface of the anchor chain 15. In addition, when the airbag 181 is compressed, the gas inside it enters the limiting plate 123 and is ejected from the jet hole 184 and blown onto the surface of the anchor chain 15. The airflow further accelerates the drying of the surface of the anchor chain 15.

[0027] like Figure 6 As shown, the limiting disk 123 is provided with an anti-fall component 19 inside. The anti-fall component 19 includes an extension seat 191 fixedly connected to one end of two adjacent water suction rollers 183, and the extension seat 191 extends through the interior of the limiting disk 123 and is slidably connected thereto. The limiting disk 123 is provided with a counterweight ball 192 inside. The frictional resistance between the extension seat 191 and the limiting disk 123 is greater than the thrust exerted by the water suction rollers 183 on the extension seat 191.

[0028] It should be noted that if the anchor chain 15 falls out of control during the anchoring process, it may cause serious safety accidents, including equipment damage, personal injury, and loss of ship control. Besides the anchor chain 15 breaking, the main cause of the anchor chain 15 falling is a malfunction in the anchoring unit 12 and the speed regulating unit 13, causing the anchoring unit 12 to rotate. To address this, when the anchor chain 15 falls, it causes the limiting disc 123 to rotate rapidly. Under high-speed rotation, the limiting disc 123 generates a strong centrifugal force, causing the counterweight ball 192, originally located at its center, to shift towards the edge. This counterweight ball 192 then presses against the extension seat 191, causing the extension seat 191 to extend beyond the limiting disc 123. This increases the depth to which the suction roller 183 inserts into the anchor chain 15. When the insertion depth of the suction roller 183 is insufficient to separate it from the anchor chain 15 during rotation, the suction roller 183 will become stuck inside the anchor chain 15, thus preventing the limiting disc 123 from rotating and preventing the anchor chain 15 from falling further, improving safety during the anchoring process.
