Description

Technical Field

[0001] This application relates to the technical field of marine equipment, and in particular to a marine anchor chain cleaning device. Background Technology

[0002] In marine engineering equipment, ship berthing and towing are particularly important. Anchor chains, steel chains connecting the hull and anchor, primarily serve to connect the anchor to the ship and transmit the anchor's holding force to the hull. When anchored, the weight of the deployed anchor chain helps to buffer external forces such as wind and currents on the ship. The portion of the anchor chain lying flat on the seabed keeps the force exerted on the anchor horizontal, which is beneficial for the anchor's reliable bottom grip. At the same time, this portion of the anchor chain, due to the resistance of the mud, also provides some anchoring force.

[0003] Anchor chains typically sink into the silt when anchoring. After retrieval, the silt remains attached to the chain. As the ship remains anchored for a period, various aquatic organisms attach to the chain. Within hours, a bacterial film forms on the chain's surface in the ocean, and within three to five days, a microbial biofilm develops. Subsequently, larvae of larger attached organisms emerge and grow, eventually forming a colony. The substances produced during the attachment, growth, and death of these organisms directly or indirectly affect the corrosion of the anchor chain metal. Currently, ships usually have anchor chain holds for storing the anchor chains. If the anchor chains are not cleaned during retrieval, the silt, mud, and bacteria on the chain will accumulate in the anchor chain hold. The mud not only corrodes the chain but also increases the load on the hold. Furthermore, the strong adsorption capacity of the attached organisms makes cleaning ineffective.

[0004] Currently, during the recovery of anchor chains, crew members typically use high-pressure fresh water rinsing to wash away impurities adhering to the anchor chain surface. However, because anchor chains are prone to entanglement with weeds and other fibrous debris, water pump rinsing cannot quickly and effectively remove these debris, resulting in poor cleaning performance. Furthermore, using only high-pressure water rinsing to remove surface deposits is a rather simplistic approach and cannot thoroughly clean the anchor chain, leading to inadequate cleaning results. Utility Model Content

[0005] To improve the cleaning effect of anchor chains, this application provides a ship anchor chain cleaning device.

[0006] This application provides a ship anchor chain cleaning device, which adopts the following technical solution:

[0007] A ship anchor chain cleaning device includes a cleaning tank installed at the anchor winch location and a cleaning device installed inside the cleaning tank. The cleaning tank is filled with cleaning fluid for cleaning the anchor chain. The cleaning device includes a brush assembly installed inside the cleaning tank. The anchor chain to be cleaned passes through the brush assembly and is immersed in the cleaning fluid in the cleaning tank.

[0008] By adopting the above technical solution, during the cleaning process of the anchor chain, the raised anchor chain can first enter the cleaning tank and be completely immersed in the cleaning solution. The soaking method removes the mud and sand and other impurities attached to the surface. Then, the set brush assembly is used to wash the anchor chain. The surface of the anchor chain is cleaned again by washing to remove stubborn algae, microorganisms and other impurities.

[0009] Optionally, the brush assembly includes a pair of vertical brushes and a pair of horizontal brushes that rotate vertically on the inner wall of the cleaning tank. The two vertical brushes are symmetrically arranged on the left and right sides of the anchor chain to be cleaned, and the two horizontal brushes are symmetrically arranged on the upper and lower sides of the anchor chain to be cleaned. The two vertical brushes and the two horizontal brushes together form a clamping fit with the anchor chain to be cleaned.

[0010] By adopting the above technical solution, during the cleaning process of the anchor chain, the two vertical brushes and the two horizontal brushes can clean the anchor chain in all directions, avoiding any omissions, thereby improving the cleaning effect of the anchor chain.

[0011] Optionally, the brush assembly further includes a control component for controlling the clamping of the two vertical brushes onto the anchor chain to be cleaned. The control component includes a cleaning frame slidably disposed inside the cleaning tank and a control hydraulic cylinder fixed on the cleaning tank. The cleaning frame is disposed along the height direction of the cleaning tank, the vertical brushes rotate vertically on the cleaning frame, and the control hydraulic cylinder controls the cleaning frame to move toward the anchor chain to be cleaned.

[0012] By adopting the above technical solution, during the washing process of the anchor chain, the hydraulic cylinder can be controlled to operate the two vertical brushes to clamp the anchor chain to be cleaned, thereby squeezing the anchor chain and achieving a more thorough washing, making the surface of the anchor chain cleaner.

[0013] Optionally, the control component further includes a control block that slides vertically inside the cleaning tank. The control block has a trapezoidal structure that is larger at the top and smaller at the bottom, and is located between the cleaning rack and the inner wall of the cleaning tank. The control hydraulic cylinder is connected to the control block, and the side of the cleaning rack facing the control block has an inclined structure that matches the control block.

[0014] By adopting the above technical solution, when controlling the two vertical brushes to clamp the anchor chain, the control hydraulic cylinder can be set on the cleaning tank and prevented from being immersed in the cleaning fluid. This changes the vertical movement of the control hydraulic cylinder to a horizontal movement, preventing damage to the control hydraulic cylinder.

[0015] Optionally, the cleaning rack has a groove along its length on the side facing the control block, a slider is fixed on the control block, the slider slides in the groove, and the cross-section of the slider is trapezoidal.

[0016] By adopting the above technical solution, during the process of controlling the movement of the cleaning rack in the cleaning liquid, the control block and the cleaning rack can achieve sliding cooperation through the cooperation of sliders and grooves, while keeping them always connected to prevent them from disengaging, so that the control block can control the bidirectional movement of the cleaning rack.

[0017] Optionally, the cleaning device includes a clamping assembly mounted on the cleaning tank. The clamping assembly includes a cleaning wheel that moves vertically on the cleaning tank and a drive component that controls the movement of the cleaning wheel. The cleaning wheel can clamp onto the anchor chain to be cleaned and immerse the cleaning wheel in the cleaning liquid in the cleaning tank.

[0018] By adopting the above technical solution, when cleaning the anchor chain, the drive unit controls the cleaning wheel to press it into the cleaning fluid, thereby allowing it to soak. After soaking, the anchor chain is more convenient to be brushed by the brush assembly.

[0019] Optionally, the driving component includes a pair of fixed frames fixed on the cleaning tank and symmetrically arranged on both sides of the cleaning wheel. A fixed shaft passes through the axis of the cleaning wheel and is rotatably engaged with the fixed shaft. The two ends of the fixed shaft are slidably arranged on the fixed frames. A pair of driving hydraulic cylinders are fixed on the cleaning tank. The two driving hydraulic cylinders are symmetrically arranged at both ends of the fixed shaft, and the ends of the driving hydraulic cylinders are connected to the ends of the fixed shaft.

[0020] By adopting the above technical solution, during the process of pressing the anchor chain to be cleaned into the cleaning tank, the hydraulic cylinder is driven to pull the two ends of the fixed shaft downwards and allow the two ends of the fixed shaft to slide along the height direction of the fixed frame, so that the cleaning wheel can better immerse the anchor chain in the cleaning fluid. During the movement of the anchor chain, the cleaning wheel and the fixed shaft are rotatably connected, which does not affect the normal rotation of the cleaning wheel.

[0021] Optionally, the clamping assembly further includes a buffer component disposed on the fixed frame. The buffer component includes a buffer spring disposed on the fixed frame, and the buffer spring is located above the fixed shaft. One end of the buffer spring is fixed to the fixed frame, and the other end is fixed to the fixed shaft.

[0022] By adopting the above technical solution, when cleaning the anchor chain, the buffer spring can press the fixed shaft. During the release of the anchor chain, the anchor chain is located outside the cleaning box. When the anchor chain is released, it will bounce to different degrees depending on the release speed, and will continuously hit the cleaning wheel. The buffer spring can reduce the impact force.

[0023] Optionally, the inlet end of the cleaning tank for conveying the anchor chain to be cleaned is provided with a flushing assembly. The flushing assembly includes a flushing box fixed to the end of the cleaning tank and multiple high-pressure nozzles fixed on the flushing box. The multiple high-pressure nozzles are arranged circumferentially along the anchor chain to be cleaned.

[0024] By adopting the above technical solution, after the anchor chain to be cleaned is raised from the water, the anchor chain can first enter the flushing box. Through the high-pressure nozzles set in all directions, the anchor chain to be cleaned is flushed with high pressure to wash away the basic debris or mud and sand attached to the anchor chain to be cleaned, so as to achieve rough cleaning. Then, after the subsequent fine cleaning steps, the debris after flushing can be kept in the flushing box to avoid flowing directly into the water.

[0025] Optionally, a maintenance component is provided at the end of the cleaning tank away from the flushing tank. The maintenance component includes a maintenance box fixed to the end of the cleaning tank and a maintenance frame fixed to the maintenance box. A maintenance sponge soaked in anti-seawater corrosion liquid is fixed on the maintenance frame. The anchor chain to be cleaned passes through the maintenance sponge, and the anti-corrosion liquid in the maintenance sponge is applied to the cleaned anchor chain.

[0026] By adopting the above technical solution, the cleaned anchor chain can be coated with a layer of curing liquid to form a protective layer, thereby protecting the anchor chain.

[0027] In summary, this application includes at least one of the following beneficial technical effects:

[0028] When cleaning the anchor chain, the flushing component can first perform a preliminary cleaning of the anchor chain, using liquid sprayed from the high-pressure nozzle to flush away mud, sand, algae and other debris attached to the anchor chain.

[0029] After the initial cleaning, the anchor chain is immersed in the cleaning solution in the cleaning tank. At the same time, the anchor chain is brushed by horizontal and vertical brushes to remove microorganisms or algae that are difficult to rinse off from its surface, thus achieving a second cleaning and improving the cleaning effect.

[0030] After cleaning, the anchor chain can be evenly coated with the maintenance solution from the maintenance sponge on the maintenance box, forming a protective layer on the anchor chain surface and protecting it from seawater corrosion. Attached Figure Description

[0039] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0040] This application discloses a ship anchor chain cleaning device.

[0041] Reference Figure 1 A ship anchor chain cleaning device includes a cleaning tank 1 installed at the anchor winch position on the ship and a cleaning device installed on the cleaning tank 1 to clean the anchor chain. The cleaning tank 1 is filled with cleaning fluid for cleaning the anchor chain. The cleaning device includes a flushing component 2 for preliminary cleaning of the anchor chain to be cleaned, a clamping component 3 and a brush component 4 installed in the cleaning tank 1, and a maintenance component 5 for maintaining the cleaned anchor chain. The flushing component 2 is located at the feed end of the cleaning tank 1, and the maintenance component 5 is located at the discharge end of the cleaning tank 1. When cleaning the anchor chain retrieved from the water, the anchor chain is first pre-cleaned by the flushing component 2, and then enters the cleaning tank 1. The clamping component 3 immerses the anchor chain in the cleaning fluid, and the brush component 4 washes the anchor chain to be cleaned. Finally, the maintenance component 5 maintains the cleaned anchor chain, allowing the cleaned anchor chain to be wound into the ship's anchor chain storage.

[0042] The flushing assembly 2 includes a flushing box 21 fixed to the end of the cleaning box 1. An annular flushing frame 22 is fixed inside the flushing box 21. The anchor chain to be cleaned passes through the flushing frame 22 along its axis. Multiple high-pressure nozzles 23 are fixed on the flushing frame 22. The multiple high-pressure nozzles 23 are evenly distributed circumferentially along the annular direction of the flushing frame 22. The nozzles of the high-pressure nozzles 23 point towards the anchor chain to be cleaned. The high-pressure nozzles 23 are connected to the water supply equipment. After the anchor chain to be cleaned is raised from the water, it can first enter the flushing box 21. The anchor chain to be cleaned is flushed with high pressure by the omnidirectionally arranged high-pressure nozzles 23 to remove the basic debris or mud and sand attached to the anchor chain. The debris after flushing can be stored in the flushing box 21, achieving preliminary cleaning.

[0043] Reference Figure 1 and Figure 2The clamping assembly 3 includes a cleaning wheel 31 that moves vertically on the cleaning tank 1 and a drive component that controls the cleaning wheel 31 to move into the cleaning tank 1. The anchor chain to be cleaned is located on the side of the cleaning wheel 31 facing the cleaning tank 1. The drive component presses the anchor chain into the cleaning tank 1. At least two sets of clamping assemblies 3 are provided in the cleaning tank 1 and can be evenly arranged along the length of the cleaning tank 1. When there are two sets of clamping assemblies 3, the two sets of clamping assemblies 3 are symmetrically arranged near both ends of the cleaning tank 1 to ensure that the anchor chain can be completely immersed in the cleaning liquid, thereby better cleaning the anchor chain. The driving component includes a pair of fixed brackets 32 fixed on the cleaning tank 1 and a pair of driving hydraulic cylinders 33 mounted on the cleaning tank 1. The fixed brackets 32 are arranged along the height direction of the cleaning tank 1, and the two fixed brackets 32 are arranged on both sides of the cleaning tank 1. A fixed shaft 34 is provided through the axis of the cleaning wheel 31, and the cleaning wheel 31 is rotatably mounted on the fixed shaft 34. The fixed brackets 32 are rectangular frame structures, and the two ends of the fixed shaft 34 are slidably fitted on the fixed brackets 32. A connecting rod 35 is provided at both ends of the two fixed shafts 34, and the two ends of the connecting rods 35 are connected to the ends of the two fixed shafts 34. The two driving hydraulic cylinders 33 are correspondingly arranged with the two connecting rods 35. The driving hydraulic cylinders 33 are located in the middle position of the connecting rods 35, and the piston rod end of the driving hydraulic cylinder 33 is fixed to the connecting rod 35. The two driving hydraulic cylinders 33 and the two connecting rods 35 are used to control the raising or lowering of two or more cleaning wheels 31, thereby pressing the anchor chain to be cleaned into the cleaning tank 1.

[0044] Furthermore, both ends of the cleaning box 1 are equipped with freely rotating auxiliary wheels 36. The auxiliary wheels 36 are located below the anchor chain to be cleaned. When the driving hydraulic cylinder 33 presses the anchor chain into the cleaning box 1, the anchor chain will rub against both ends of the cleaning box 1. In order to ensure that the anchor chain can be pulled normally, the anchor chain can contact the auxiliary wheels 36, so as to pull the anchor chain better.

[0045] Reference Figure 1 and Figure 2 The clamping assembly 3 also includes a buffer component mounted on the fixed frame 32. The buffer component includes a buffer spring 37 mounted on the fixed frame 32 and a guide rod 38 slidably mounted on the fixed frame 32. The guide rod 38 slides along the length of the fixed frame 32 and passes through the fixed frame 32. The lower end of the guide rod 38 is fixed to the end of the fixed shaft 34. The buffer spring 37 is sleeved on the guide rod 38 and located inside the fixed frame 32. The upper end of the buffer spring 37 is fixed to the fixed frame 32, and the lower end is fixed to the end of the fixed shaft 34. When cleaning the anchor chain, the buffer spring 37 can clamp the fixed shaft 34. During the release of the anchor chain, the anchor chain is located outside the cleaning box 1. When the anchor chain is released, it will bounce to different degrees depending on the release speed of the anchor chain and will continuously hit the cleaning wheel 31. The buffer spring 37 can reduce the impact force.

[0046] Reference Figure 1 and Figure 3 The brush assembly 4 includes a pair of vertical brushes 41 and a pair of horizontal brushes 42 that rotate vertically on the inner wall of the cleaning tank 1. The two vertical brushes 41 are symmetrically arranged on the left and right sides of the anchor chain, and the two horizontal brushes 42 are symmetrically arranged on the upper and lower sides of the anchor chain. When cleaning the anchor chain, the anchor chain to be cleaned passes between the two vertical brushes 41 and the two horizontal brushes 42. A connecting shaft 421 is provided on the axis of the horizontal brushes 42, and the horizontal brushes 42 rotate on the connecting shaft 421. Since the anchor chain to be cleaned needs to be lifted out of the cleaning tank 1 after cleaning, the horizontal brushes 42 located on the upper side of the anchor chain are movable. One end of its connecting shaft 421 is hinged to the inner wall of the cleaning tank 1, and the other end is snapped into the inner wall of the cleaning tank 1. Inside the cleaning tank 1 located at the movable end of the connecting shaft 421... A snap-fit ​​block 43 is fixed to the wall, and a snap-fit ​​groove is provided on the snap-fit ​​block 43. The movable end of the connecting shaft 421 is snapped into the snap-fit ​​groove. An insert rod 431 is inserted through the snap-fit ​​block 43 and passes through the end of the connecting shaft 421, so that the movable end of the connecting shaft 421 is fixed to the snap-fit ​​block 43. Pins are inserted at both ends of the insert rod 431 to prevent the insert rod 431 from falling off the insert block during the cleaning of the anchor chain. After the anchor chain is immersed in the cleaning solution, the movable end of the connecting shaft 421 on the movable transverse brush 42 is connected and fixed to the snap-fit ​​block 43 for normal cleaning. After cleaning, the anchor chain needs to be lifted out of the cleaning tank 1, and the insert rod 431 is removed from the snap-fit ​​block 43. During the lifting process, the anchor chain lifts the movable transverse brush 42. A pair of horizontal brushes 42 and a pair of vertical brushes 41 are used together, and different numbers of horizontal brushes 42 and vertical brushes 41 can be selected according to actual needs to improve the cleaning effect.

[0047] Furthermore, an ultrasonic cleaning device 6 is installed inside the cleaning tank 1. During the cleaning of the anchor chain by the vertical brush 41 and the horizontal brush 42, the ultrasonic cleaning device 6 is activated at the same time. Under the action of ultrasonic waves, every corner of the anchor chain can be cleaned, making the anchor chain cleaner more thorough and improving the cleaning effect.

[0048] Reference Figure 1 , Figure 3 and Figure 4The brush assembly 4 also includes two sets of control components 44 for controlling the relative movement of the two vertical brushes 41. Each control component 44 includes a control block 441 that slides vertically on the inner wall of the cleaning tank 1 and a hydraulic cylinder 442 that moves the control block 441. A horizontally moving cleaning frame 443 is installed inside the cleaning tank 1. The height of the cleaning frame 443 is the same as the height of the cleaning tank 1, and the cleaning frame 443 moves towards the anchor chain. The vertical brushes 41 are rotatably mounted on the cleaning frame 443. The control block 441 moves along the height of the cleaning tank 1 and has a trapezoidal structure that is larger at the top and smaller at the bottom. 1 is located between the inner wall of the cleaning frame 443 and the cleaning tank 1. The side of the cleaning frame 443 facing the control block 441 has an inclined structure, allowing the inclined surface of the control block 441 to slide and engage with the inclined surface of the cleaning frame 443. When the control block 441 moves downward, the cleaning frame 443 moves horizontally. A slider 444 with a trapezoidal cross-section is fixed on the inclined surface of the control block 441. A matching groove 445 is provided on the inclined surface of the cleaning frame 443. The slider 444 slides into the groove 445, allowing the control block 441 and the cleaning frame 443 to slide and connect without disengaging. When the control block 441 moves upward, the cleaning frame 443 moves away from the anchor chain. The control hydraulic cylinder 442 is in the same height direction as the cleaning tank 1 and is fixed on the cleaning tank 1. The piston rod end of the control hydraulic cylinder 442 is fixed to the control block 441 and is used to operate the vertical movement of the control block 441. After the cleaning anchor chain moves between the two vertical brushes 41, the control hydraulic cylinder 442 is activated, controlling the vertical brushes 41 to press against the anchor chain, thereby allowing the two vertical brushes 41 to press against the anchor chain and improve the cleaning effect on the anchor chain.

[0049] Reference Figure 1 The maintenance component 5 includes a maintenance box 51 fixed to the end of the cleaning box 1 and a maintenance frame 52 fixed inside the maintenance box 51. A maintenance sponge 53 is fixed on the maintenance frame 52. The maintenance sponge 53 is soaked in a maintenance liquid that prevents seawater corrosion. The cleaned anchor chain can pass through the maintenance sponge 53 and the maintenance liquid can be applied to the anchor chain to maintain it and improve its corrosion resistance.

[0050] The implementation principle of a ship anchor chain cleaning device according to an embodiment of this application is as follows: When cleaning the anchor chain, the anchor chain first passes through the flushing box 21, where water sprayed by the high-pressure nozzle 23 flushes the anchor chain. Then, it enters the cleaning box 1, where the pressing component 3 presses the anchor chain into the cleaning solution in the cleaning box 1 for immersion. Then, it is brushed in all directions by the brush component 4. During the brushing process, the ultrasonic cleaning device 6 is started simultaneously to clean without dead angles. After cleaning, the anchor chain enters the maintenance box 51, where a maintenance liquid is applied to the surface of the anchor chain to form a protective layer and improve the protective effect.
