Description

Technical Field

[0001] The utility model relates to the technical field of ship anchor cleaning, in particular to a novel liquefied ship anchor chain cleaning device. Background Art

[0002] Cleaning the anchor chain of liquefied petroleum vessels is an important part of ship maintenance. Since the anchor chain is immersed in highly corrosive seawater for a long time, various marine organisms, seaweed and dirt will be attached to it. These attachments will not only increase the weight of the anchor chain, but may also cause corrosion to the anchor chain, affecting its performance and safety. Secondly, as more and more liquefied petroleum vessels enter inland ports, the anchor chain is not cleaned thoroughly enough, resulting in excessive garbage or silt in the anchor chain compartment, which is difficult for the crew to clean.

[0003] A bacterial film forms on the surface of the anchor chain within a few hours in the ocean, and a microbial mucosa forms in three to five days. After that, the larvae of large attached organisms appear and grow, eventually forming a colony of attached organisms. The substances produced during the attachment, growth, and death of the organisms will directly or indirectly affect the corrosion of the anchor chain metal.

[0004] For example, patent CN 221269079U discloses a ship anchor chain flushing device, comprising an anchor chain barrel and an anchor chain body, the anchor chain body passing through the anchor chain barrel, and nine anchor chain nozzles provided on the anchor chain barrel, each of the anchor chain nozzles being connected to a flushing water pipe, and the nine anchor chain nozzles being divided into three first-layer nozzles, three second-layer nozzles and three third-layer nozzles according to their positions. This utility model arranges the flushing nozzles in three layers, with the nozzles of each layer evenly distributed along the outer edge of the anchor chain barrel, and the nozzles of different layers being arranged in a spiral shape, that is, the nozzles of each layer are staggered at a certain angle to the nozzles of the upper layer, and the flushing nozzles are at a certain angle to the center of the anchor chain barrel, which is conducive to more uniform flushing of the water column and increases the effective flushing area. The water sources of the three layers of anchor chain nozzles are the same and they spray at the same time. The water dripping from the upper layer has a pre-cleaning effect on the silt adhered to the anchor chain below, thereby enhancing the effect.

[0005] When using the above technology, it was found that the existing technology has the following technical problems: the existing technology cleans the anchor chain by high-pressure flushing, but this flushing method can only simply clean the substances on the surface of the anchor chain, and high-pressure flushing cannot effectively and thoroughly clean the bacterial film and biological community on the surface of the anchor chain. Therefore, the existing technology lacks a cleaning mechanism that directly contacts the anchor chain, and the cleaning mechanism cooperates with high-pressure flushing to achieve an effective cleaning effect. To this end, we designed a new type of liquefied ship anchor chain cleaning device to provide another technical solution to the above technical problems. Utility Model Content

[0006] Based on this, it is necessary to provide a new type of liquefied ship anchor chain cleaning device to address the above technical problems. When the anchor chain needs to be cleaned, the anchor chain tube is put on the outside of the anchor chain, and then the cleaning mechanism drives the four transmission arms and cleaning rollers to deeply scrub the surface of the anchor chain, so that the four anchor chains are in contact in the direction of approaching each other, so that the cleaning rollers can effectively further thoroughly clean the bacterial film and biological community on the surface of the anchor chain, thereby improving the cleaning effect of the anchor chain, increasing the service life of the anchor chain, and facilitating the effective positioning, maintenance and cleaning of the anchor chain.

The outer side of the threaded rail is threadedly connected to a threaded sleeve, and the bottom end of the threaded sleeve is slidably connected to a transmission rod, and the transmission rod is away from one end of the threaded sleeve and is rotatably connected to a connecting rod and a guide column through the limiting groove. The end of the connecting rod is away from the transmission rod and is rotatably connected to the middle part of the transmission arm, and the inside of the guide column is slidably connected to a telescopic slide rod, and the end of the telescopic slide rod is away from the guide column and is rotatably connected to the end of the transmission arm.

[0010] As a preferred embodiment of the new type of liquefied ship anchor chain cleaning device provided by the utility model, a T-slot is provided at the bottom end of the threaded rotating sleeve, and four T-slot sliders are slidably connected to the inner side of the T-slot, and the bottom end of the T-slot slider is rotatably connected to the transmission rod.

[0011] As a preferred embodiment of the novel liquefied vessel anchor chain cleaning device provided by the utility model, the telescopic slide rod, the guide column, the connecting rod and the middle portion of the transmission arm form a small triangular area.

[0012] As a preferred embodiment of the novel liquefied ship anchor chain cleaning device provided by the utility model, a spring is assembled inside the guide column, one end of the spring is fixed to the guide column, and the other end of the spring is fixed to the telescopic slide rod.

[0013] As a preferred embodiment of the novel liquefied ship anchor chain cleaning device provided by the utility model, a hard bristle brush is sleeved on the outer side of the cleaning roller, and the hard bristle brush is used to brush the anchor chain.

[0014] As a preferred embodiment of the novel liquefied vessel anchor chain cleaning device provided by the present invention, a plurality of rotating handles are fixed to the outer side of the threaded rotating sleeve.

[0015] As a preferred embodiment of the novel liquefied ship anchor chain cleaning device provided by the utility model, the top and bottom ends of the outer side of the anchor chain barrel are both provided with high-pressure flushing mechanisms for cleaning the anchor chain. Taking one of the high-pressure flushing mechanisms as an example, the high-pressure flushing mechanism includes several spray assemblies, which are used to flush the surface of the anchor chain.

[0019] At the same time, through the above technical solutions, the present invention has at least the following beneficial effects:

[0020] The utility model provides a new type of liquefied ship anchor chain cleaning device

[0021] 1. The rotating shaft seat drives the threaded sleeve downward. At this time, the T-slot and the T-slider slide, and the threaded sleeve presses the T-slider, causing the T-slider to drive the transmission rod to squeeze the guide post. The guide post drives the telescopic slide rod and spring to press the transmission arm, and the transmission arm drives the cleaning roller and hard brush to deeply clean the anchor chain.

[0022] 2. The elastic force of the spring drives the telescopic slide rod, transmission arm and cleaning roller to resist the anchor chain. Since the transmission arm and the cleaning roller are connected with damping rotation, the elastic force of the spring effectively increases the friction between the cleaning roller and the hard bristle brush and the anchor chain, which facilitates the cleaning roller and the hard bristle brush to clean the anchor chain;

[0023] 3. The high-pressure water flow ejected from the nozzle will generate a reverse force on the high-pressure water pipe, causing the high-pressure water pipe to drive the nozzle to slide away from the anchor chain. The closer the distance between the nozzle and the anchor chain, the greater the reverse force generated, causing the nozzle to move farther away from the anchor chain. The nozzle drives the rubber compensation pipe to expand and contract, so the nozzle can automatically adjust according to the distance from the anchor chain, so that the nozzle collides with the surface while flushing the anchor chain.

[0035] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0036] As described in the background art, the prior art cleans the anchor chain by high-pressure flushing, but this flushing method can only simply clean the substances on the surface of the anchor chain, and the high-pressure flushing cannot effectively and thoroughly clean the bacterial film and biological community on the surface of the anchor chain. Therefore, the prior art lacks a cleaning mechanism that is in direct contact with the anchor chain, and the cleaning mechanism cooperates with the high-pressure flushing to achieve an effective cleaning effect.

[0037] In order to solve this technical problem, the utility model provides a novel liquefied ship anchor chain cleaning device.

[0038] Specifically, please refer to Figures 1-9 A new type of liquefied vessel anchor chain cleaning device specifically includes:

[0039] The anchor chain barrel 1 is provided with four cleaning mechanisms for brushing the anchor chain. Taking one of the cleaning mechanisms as an example, the cleaning mechanism includes a rotating shaft seat 4, a transmission arm 5 and a cleaning roller 6. The rotating shaft seat 4 is fixed to the inner wall of the anchor chain barrel 1. The transmission arm 5 is rotatably connected to the inner side of the rotating shaft seat 4. The end of the transmission arm 5 away from the rotating shaft seat 4 is connected to the cleaning roller 6 in a damped rotation. The outer side of the cleaning roller 6 brushes the anchor chain.

[0040] The utility model provides a novel anchor chain cleaning device for liquefied gas vessels. When the anchor chain needs to be cleaned, the anchor chain barrel 1 is sleeved on the outside of the anchor chain, and then the cleaning mechanism drives four transmission arms 5 and the cleaning roller 6 to deeply scrub the surface of the anchor chain, so that the four anchor chains are in contact with each other in a direction close to each other, so that the cleaning roller 6 can effectively further thoroughly clean the bacterial film and biological community on the surface of the anchor chain, thereby improving the cleaning effect of the anchor chain, increasing the service life of the anchor chain, and facilitating effective positioning, maintenance and cleaning of the anchor chain.

[0041] In order to enable those skilled in the art to better understand the solution of the present invention, the technical solution in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0042] It should be noted that, in the absence of conflict, the embodiments of the present invention and the features and technical solutions therein can be combined with each other.

[0043] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, it does not need to be further defined or explained in subsequent drawings.

[0044] Example 1

[0045] Reference Figure 1-Figure 7 A novel anchor chain cleaning device for liquefied petroleum vessels includes an anchor chain drum 1. Four cleaning mechanisms for brushing the anchor chain are provided inside the anchor chain drum 1. Taking one of the cleaning mechanisms as an example, the cleaning mechanism includes a rotating shaft seat 4, a transmission arm 5, and a cleaning roller 6. The rotating shaft seat 4 is fixed to the inner wall of the anchor chain drum 1. The transmission arm 5 is rotatably connected to the inner side of the rotating shaft seat 4. The end of the transmission arm 5 away from the rotating shaft seat 4 is connected to the cleaning roller 6 in a damped rotation manner. The outer side of the cleaning roller 6 brushes the anchor chain.

[0046] Specifically, when the anchor chain needs to be cleaned, the anchor chain barrel 1 is put on the outside of the anchor chain, and then the cleaning mechanism drives the four transmission arms 5 and the cleaning rollers 6 to deeply scrub the surface of the anchor chain, so that the four arms contact the anchor chain in a direction close to each other, so that the cleaning rollers 6 can effectively and thoroughly clean the bacterial film and biological community on the surface of the anchor chain, thereby improving the cleaning effect of the anchor chain, increasing the service life of the anchor chain, and facilitating effective positioning, maintenance and cleaning of the anchor chain.

[0047] In this embodiment, the cleaning mechanism and the limiting groove 10 are multiple-arranged according to the cleaning angle, mainly used to increase the cleaning surface of the anchor chain;

[0048] A threaded rail 22 is welded to the outside of the anchor chain tube 1. Limiting grooves 10 are provided at the four ends of the interior of the anchor chain tube 1. The outer side of the threaded rail 22 is threadedly connected to a threaded sleeve 2. The bottom end of the threaded sleeve 2 is slidably connected to a transmission rod 8. The transmission rod 8 is away from one end of the threaded sleeve 2 and passes through the limiting groove 10 to be rotatably connected to a connecting rod 7 and a guide column 12. The end of the connecting rod 7 away from the transmission rod 8 is rotatably connected to the middle part of the transmission arm 5. The interior of the guide column 12 is slidably connected to a telescopic slide rod 13. The telescopic slide rod 1 The end away from the guide post 12 is rotatably connected to the end of the transmission arm 5. A spring 14 is installed inside the guide post 12. One end of the spring 14 is fixed to the guide post 12, and the other end of the spring 14 is fixed to the telescopic slide 13. The limiting groove 10 is used to limit the T-shaped slider 9 and the transmission rod 8 to prevent the rotating threaded sleeve 2 from causing the T-shaped slider 9 and the transmission rod 8 to rotate synchronously. The connecting rod 7 is used to limit the angle of the guide post 12 and the transmission rod 8 to prevent them from exceeding the movement trajectory of the connecting rod 7 during movement.

[0049] A T-slot 11 is provided at the bottom end of the threaded sleeve 2. Four T-slide blocks 9 are slidably connected to the inner side of the T-slot 11. The bottom end of the T-slide block 9 is rotatably connected to the transmission rod 8. When the threaded sleeve 2 is rotated and moves up and down along the threaded linear rail 22, the T-slot 11 and the four T-slide blocks 9 slide, and the T-slot 11 effectively drives the T-slide blocks 9 to apply pressure to the transmission rod 8. A hard brush is sleeved on the outer side of the cleaning roller 6, and the hard brush is used to brush the anchor chain.

[0050] Specifically, when it is necessary to clean the anchor chain, the threaded sleeve 2 is rotated to reciprocate up and down along the threaded linear rail 22. When the threaded sleeve 2 is rotated and moved downward, the threaded sleeve 2 and the T-shaped slider 9 slide, and then the threaded sleeve 2 applies pressure to the T-shaped slider 9, so that the T-shaped slider 9 drives the transmission rod 8 to squeeze the guide post 12. At this time, the guide post 12 drives the telescopic slide rod 13 and the spring 14 to apply pressure to the transmission arm 5, so that the transmission arm 5 drives the cleaning roller 6 and the hard bristle brush to deeply clean the anchor chain, and the elastic force of the spring 14 drives the telescopic slide rod 13, the transmission arm 5 and the cleaning roller 6 to resist the anchor chain. Since the transmission arm 5 is connected to the cleaning roller 6 in a damped rotation, the elastic force of the spring 14 effectively increases the friction between the cleaning roller 6 and the anchor chain, which is conducive to the cleaning roller 6 to brush the anchor chain;

[0051] The telescopic slide rod 13, the guide post 12, the connecting rod 7 and the middle part of the transmission arm 5 form a small triangular area, thereby effectively improving the sliding stability of the telescopic slide rod 13 and the guide post 12;

[0052] A plurality of rotating handles 3 are fixed to the outer side of the threaded rotating sleeve 2 , and the ventilation pipe rotating handles 3 effectively increase the rotation convenience of the threaded rotating sleeve 2 .

[0053] Example 2

[0054] Reference Figure 8 and Figure 9 A novel anchor chain cleaning device for liquefied fuel vessels is provided. The top and bottom ends of the outer side of the anchor chain barrel 1 are both provided with high-pressure flushing mechanisms for cleaning the anchor chain. Taking one of the high-pressure flushing mechanisms as an example, the high-pressure flushing mechanism includes several spray assemblies, which are used to flush the surface of the anchor chain.

[0055] When the anchor chain needs to be cleaned, the anchor chain passes through the interior of the anchor chain barrel 1 from top to bottom, and the surface of the anchor chain is first pre-washed by the high-pressure flushing mechanism at the top to flush out the adsorbed substances, and then the four cleaning rollers 6 and the hard-bristle brushes are pressed and deeply brushed in the direction of approaching each other, thereby effectively cleaning the bacterial film and biological community adsorbed on the surface of the anchor chain. After the cleaning rollers 6 and the hard-bristle brushes have finished brushing, the high-pressure flushing mechanism at the bottom is used to flush the bacterial film and biological community that have fallen off the cleaning rollers 6 and the hard-bristle brushes, thereby effectively cleaning the bacterial film and biological community adsorbed on the surface of the anchor chain;

[0056] The spray assembly includes a fixed pipe 15, a nozzle 16, a rubber compensating pipe 17, a reducing flange 18, an adjustment plate 19, a connecting flange 20, and a high-pressure water pipe 21. The outer side of the interior of the anchor chain barrel 1 is fixed to the fixed pipe 15. The right end of the fixed pipe 15 is fixed with the reducing flange 18. The right end of the reducing flange 18 is equipped with a rubber compensating pipe 17. The right end of the rubber compensating pipe 17 is equipped with an adjustment plate 19. The inner wall of the nozzle 16, reducing flange 18, rubber compensating pipe 17, and adjustment plate 19 is provided with a high-pressure water pipe 21. The left end of the high-pressure water pipe 21 is fixed with the nozzle 16. The right end of the high-pressure water pipe 21 is connected to the external pumping equipment.

[0057] An external water pumping device is connected to the high-pressure water pipe 21, thereby forming a high-pressure water flow from the inside of the nozzle 16 to clean the anchor chain. During the cleaning process, the high-pressure water flow ejected from the nozzle 16 will generate a reverse force on the high-pressure water pipe 21, causing the high-pressure water pipe 21 to drive the nozzle 16 to slide away from the anchor chain. The closer the distance between the nozzle 16 and the anchor chain, the greater the reverse force generated, causing the nozzle 16 to move further away from the anchor chain. The nozzle 16 drives the rubber compensating pipe 17 to expand and contract, and the rubber compensating pipe 17 has a certain elastic effect.

[0058] When the reverse force of the nozzle 16 is the largest, the nozzle 16 drives the rubber compensation tube 17 to contract to the maximum. Conversely, the farther the distance between the nozzle 16 and the anchor chain is, the smaller the reverse force is, and the smaller the contraction distance of the rubber compensation tube 17 is. Therefore, the nozzle 16 can automatically adjust according to the distance of the anchor chain to prevent the nozzle 16 from contacting and colliding with the anchor chain.

[0059] The use process of the new type of liquefied ship anchor chain cleaning device provided by the utility model is as follows:

[0060] Working principle:

[0061] When the anchor chain needs to be cleaned, an external water pumping device is connected to the high-pressure water pipe 21, thereby forming a high-pressure water flow to clean the anchor chain from the inside of the nozzle 16. During the cleaning process, the high-pressure water flow ejected from the inside of the nozzle 16 will generate a reverse force on the high-pressure water pipe 21, so that the high-pressure water pipe 21 drives the nozzle 16 to slide in the direction away from the anchor chain. The closer the distance between the nozzle 16 and the anchor chain, the greater the reverse force generated, so that the nozzle 16 is farther away from the anchor chain. The nozzle 16 drives the rubber compensation pipe 17 to expand and contract, so that the nozzle 16 can automatically adjust according to the distance from the anchor chain, so that the nozzle 16 collides with the surface while washing the anchor chain;

[0062] When the rotating shaft seat 4 drives the threaded sleeve 2 to move downward, the T-slot 11 and the T-slider 9 slide, and then the threaded sleeve 2 applies pressure to the T-slider 9, so that the T-slider 9 drives the transmission rod 8 to squeeze the guide column 12, and the guide column 12 drives the telescopic slide rod 13 and the spring 14 to apply pressure to the transmission arm 5, so that the transmission arm 5 drives the cleaning roller 6 and the hard brush to deeply clean the anchor chain. When the elastic force of the spring 14 drives the telescopic slide rod 13, the transmission arm 5 and the cleaning roller 6 to resist the anchor chain, since the transmission arm 5 and the cleaning roller 6 are connected with the damping rotation, the elastic force of the spring 14 effectively increases the friction between the cleaning roller 6 and the hard brush and the anchor chain, which is beneficial for the cleaning roller 6 and the hard brush to scrub the anchor chain. Finally, the cleaned anchor chain is rinsed through several nozzles 16 at the bottom, effectively cleaning the bacterial film and biological community adsorbed on the surface of the anchor chain.
