Description

Technical Field

[0001] This invention relates to the field of winch technology, and in particular to a method for a lightweight drum structure for a shipboard winch used for hydrological and meteorological observation. Background Technology

[0002] A winch is a mechanical device that uses a drum to wind a steel wire rope or chain to lift, pull, or move heavy objects. It is widely used in construction, ports, mines, marine engineering and other fields. When conducting hydrological and meteorological observations of the ocean, it is necessary to place sensors such as thermometers, salinity meters, current meters, and weather stations at designated depths or locations, which requires the use of winches.

[0003] For example, the "A Winch Drum Structure" with announcement number "CN220564185U" enables the drum structure to clean, humidify, or spray protective agents onto ropes by setting up a slider, a liquid spray nozzle, and a drying nozzle. This solves the problems of low safety and difficulty in handling ropes in existing drum structures.

[0004] Since marine winches are used in the ocean, where there is a lot of salt spray, chloride ions in the salt spray can penetrate the oxide film on the surface of the wire rope, forming a micro-battery effect in local areas. This can lead to pitting corrosion, crevice corrosion, and even stress corrosion cracking. Furthermore, the wire rope is prone to accelerated wear on the drum, which can easily affect the service life of both the wire rope and the drum. Wire rope cracks can also affect the use of the winch. While the wire rope only needs to be cleaned periodically, if the cleaning equipment is still in contact with the wire rope during normal winch use, it will interfere with the lubrication layer on the wire rope, thus easily accelerating the wear of the wire rope and affecting the service life of the winch drum and the wire rope. Summary of the Invention

[0005] The purpose of this invention is to provide a lightweight drum structure for a shipboard hydrological and meteorological observation winch, which allows the rotating ring on the left to rotate along with the connecting plate, cleaning frame, and rotating ring on the right, thereby enabling the brush bristles to rotate slightly to clean the wire rope, ensuring the cleaning effect against salt spray, further reducing the corrosion of the wire rope by salt spray, and further improving the service life of the wire rope and the drum, thus solving the problems mentioned in the background art.

A motion component, configured inside the guide frame, is used to control the cleaning section and the drying wheel as they move closer to and away from the wire rope.

[0007] Preferably, the cleaning unit includes a cleaning frame fixedly connected between two corresponding connecting plates. Brush bristles are fixedly connected to the cleaning frame near the wire rope. Spray holes are opened on the inner side of the cleaning frame. The connecting plate on the right side is hollow. The cleaning frame is connected to the rotating ring on the right side through the connecting plate on the right side. A water inlet groove is opened inside the rotating ring on the right side. A water inlet hose is inserted into the right side of the rotating ring on the right side.

[0008] Preferably, the motion assembly includes a ring frame rotatably connected to the right side of the motion ring, a squeezing frame fixedly connected to the inner side of the ring frame, an inclined block fixedly connected to the outer side of the cleaning frame, the top of the inclined block being inclined, and a spring fixedly connected between the connecting plate and the rotating ring.

[0009] Preferably, the inner side of the extrusion frame is rotatably connected to a rotating shaft for reducing motion friction, and the bottom of the extrusion frame is located at the opening and sleeved on both sides of the inclined block.

[0010] Preferably, a guide slider is fixedly connected to the outer side of the rotating ring on the left, and a guide groove is opened on the inner side of the moving ring. The guide slider slides inside the guide groove. An electric telescopic rod is fixedly connected inside the guide frame, and the output shaft of the electric telescopic rod is fixedly connected to the moving ring.

[0011] Preferably, the right side of the guide groove is straight and the left side of the guide groove is spiral.

[0012] Preferably, a sleeve is fixedly connected to the front slide, the end of which extends into the interior of the drying wheel, and the outer side of the sleeve is rotatably connected to the drying wheel. The interior of the rear slide is hollow, and a through tube is rotatably inserted into the front end of the rear slide, with the front end of the through tube inserted into the interior of the sleeve. A preheating frame is fixedly connected to the rear end of the guide frame, and a bent tube is fixedly inserted between the preheating frame and the rear slide. A push plate is fixedly connected to the rear end of the moving ring through the guide frame, and a bellows is fixedly connected between the push plate and the preheating frame. An air inlet pipe is fixedly inserted into the top of the bellows, and an air outlet pipe is fixedly inserted into the left side of the bellows. Check valves are installed inside both the air inlet and air outlet pipes, and the air outlet pipe is inserted into the interior of the preheating frame.

[0013] Preferably, a drying cotton is fixedly connected to the outer side of the drying wheel, and a drying hole is provided on the drying wheel near the drying cotton.

[0014] Preferably, the sleeve is connected to the inside of the drying wheel, and the connecting plates at the top and bottom ends on the left side are fixedly connected to the bending frame, the ends of the bending frame being fixedly connected to the sleeve.

[0015] A method for preventing clogging in domestic sewage treatment includes the following steps: S1. Position adjustment: The cleaning section and the drying wheel are brought closer to the steel wire rope by the motion component. S2. Cleaning: The cleaning department cleans the wire rope, the drying wheel dries the wire rope, and the oil spraying assembly sprays lubricating oil onto the wire rope.

[0016] Compared with the prior art, the beneficial effects of the present invention are: 1. Through the action of the moving components, the cleaning part and the drying wheel can come into contact with the wire rope during cleaning, while the connecting plate, along with the cleaning frame and bristles, can move away from the wire rope when the winch is running normally. At this time, the structure used for cleaning will not come into contact with the wire rope, thus avoiding interference with the lubrication layer on the wire rope and reducing wear on the wire rope, thereby improving the service life of the winch drum and the wire rope. 2. When cleaning the wire rope, the output shaft of the electric telescopic rod reciprocates slightly. At this time, the guide slider moves inside the spiral part of the guide groove. This allows the rotating ring on the left to rotate along with the connecting plate, cleaning frame, and rotating ring on the right. This causes the bristles to rotate slightly to clean the wire rope, ensuring the cleaning effect of the salt spray on the wire rope, further reducing the corrosion of the wire rope by the salt spray, and further improving the service life of the wire rope and the rope drum. 3. When the output shaft of the electric telescopic rod extends, the cleaning frame moves with the connecting plate on the left side. At this time, the wiping cotton on the inside of the wiping wheel comes into contact with the wire rope to wipe away the residual water after cleaning, thereby improving the effect of lubricating oil adhering to the wire rope, thus ensuring the lubrication effect when the wire rope is wound, reducing wear and damage to the wire rope and the drum, and improving the service life of the wire rope and the drum. 4. The heated air acts on the wiping cotton through the drying hole, thereby drying the moisture on the wiping cotton to ensure the drying effect of the wire rope in the future. This further improves the adhesion of the lubricating oil to the wire rope when the lubricating oil is sprayed, ensures the lubrication effect when the wire rope is wound, reduces the wear and damage of the wire rope and the drum, and improves the service life of the wire rope and the drum.

[0020] 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 embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0021] Example 1: Please refer to Figures 1 to 10 This invention provides a technical solution: a lightweight drum structure for a shipboard hydrological and meteorological observation winch, comprising a body 1, a rope drum 2 rotatably mounted on the top of the body 1, a steel wire rope fixedly wound on the rope drum 2, a guide frame 3 for preventing the rope drum 2 from getting tangled, a drive assembly 4 for driving the guide frame 3 to move on the top of the body 1, the drive assembly 4 including a reciprocating screw threaded to the bottom of the guide frame 3, the end of the reciprocating screw being rotatably connected to the body 1, and pulleys fixedly connected to the mounting shaft of the rope drum 2 and the end of the reciprocating screw, with a belt connecting the two pulleys. When the rope drum 2 rotates, the reciprocating screw can be rotated under the transmission action between the two pulleys and the belt, facilitating the movement of the guide frame 3 in the front-back direction.

[0022] It should be noted that rotating guide wheels are provided on both the left and right sides and at the front and rear ends of the guide frame 3. The steel wire rope passes through the inside of the guide wheel. When the guide frame 3 moves along the front and back direction with the guide wheel, it can provide traction for the steel wire rope and prevent the steel wire rope from becoming tangled. The transmission ratio of the belt pulley and the pitch of the reciprocating screw are reasonably configured to ensure uniform traction of the steel wire rope. This technology is a mature existing technology and will not be described in detail.

[0023] It should be noted that the symmetrical arrangement of the guide wheels on both sides ensures that the wire rope located inside the guide frame 3 is kept taut.

[0024] The left side of the guide frame 3 is equipped with an oil spraying assembly 8. The lightweight drum structure of the winch also includes a cleaning assembly 5 disposed inside the guide frame 3 for cleaning the surface of the wire rope with salt spray. The cleaning assembly 5 includes a fixed ring 51 fixedly connected inside the guide frame 3. A moving ring 52 is slidably connected inside the guide frame 3 to the left of the fixed ring 51. Both the moving ring 52 and the fixed ring 51 are equipped with rotating rings 55. The two rotating rings 55 are slidably connected to connecting plates 53 in a circular array. A cleaning part 54 is disposed between the two corresponding connecting plates 53. The fixed ring 51 is rotatably connected to the rotating ring 55 on the right side, and the moving ring 52 is movably connected to the rotating ring 55 on the left side.

[0025] The lightweight drum structure of the winch also includes a drying assembly 6 located on the left side of the motion ring 52. The drying assembly 6 includes slide blocks 61 that are slidably connected to the front and rear ends of the guide frame 3, and drying wheels 62 are arranged between the two slide blocks 61.

[0026] The lightweight drum structure of the winch also includes a motion component 7 disposed inside the guide frame 3, which controls the cleaning section 54 and the drying wheel 62 to move closer to and away from the wire rope.

[0027] The cleaning unit 54 includes a cleaning frame 541 fixedly connected between two corresponding connecting plates 53. Brush bristles 542 are fixedly connected to the cleaning frame 541 near the wire rope. Spray holes are opened on the inner side of the cleaning frame 541. The connecting plate 53 on the right side is hollow. The cleaning frame 541 is connected to the rotating ring 55 on the right side through the connecting plate 53 on the right side. A water inlet groove 543 is opened inside the rotating ring 55 on the right side. A water inlet hose 544 is inserted into the right side of the rotating ring 55 on the right side. The water inlet hose 544 is made of flexible material.

[0028] The motion assembly 7 includes a ring frame 71 rotatably connected to the right side of the motion ring 52. A squeezing frame 72 is fixedly connected to the inner side of the ring frame 71. An inclined block 73 is fixedly connected to the outer side of the cleaning frame 541. The top of the inclined block 73 is inclined. A spring 74 is fixedly connected between the connecting plate 53 and the rotating ring 55. A rotating shaft 75 for reducing motion friction is rotatably connected to the inner side of the squeezing frame 72. The bottom of the squeezing frame 72 is located at the opening and sleeved on both sides of the inclined block 73.

[0029] By adopting the above technical solution, after the winch has been used for a period of time, due to the accumulation of salt spray, it is necessary to clean the wire rope in order to prevent damage to the wire rope and the winding drum 2.

[0030] It should be noted that during normal operation of the winch, the cleaning part 54 and the drying wheel 62 do not come into contact with the wire rope under the action of the moving component 7, thus avoiding interference with the lubrication layer on the wire rope and reducing wear on the wire rope, thereby improving the service life of the winch drum and the wire rope.

[0031] It should be noted that the rope drum 2 is made of lightweight metal material, thus achieving its lightweight design.

[0032] When cleaning the wire rope, the wire rope is first unwound, and then the output shaft of the electric telescopic rod 9 is retracted, causing the moving ring 52 to move to the right, which in turn causes the ring frame 71 to move to the right. At this time, the compression frame 72 moves to the right along with the rotating shaft 75, which in turn compresses the corresponding inclined block 73. The inclined block 73, under compression, brings the cleaning frame 541 and brush bristles 542 closer to the wire rope. After the output shaft of the electric telescopic rod 9 retracts, the wire rope is wound up by the rope drum 2. During the winding of the wire rope, the wire rope moves, and the brush bristles 542 clean the surface of the wire rope, removing salt spray from the wire rope, thus preventing accelerated wear on the wire rope and the rope drum 2 and improving the service life of the wire rope and the rope drum 2.

[0033] When cleaning the wire rope, external clean water is introduced into the water inlet tank 543 through the water inlet hose 544. Then, the clean water is introduced into the hollow position of the connecting plate 53 on the right side and then enters the temporal part of the cleaning frame 541. Finally, it is sprayed onto the wire rope from the spray nozzle. This allows for cleaning by simultaneously spraying water and brushing with the bristles 542, which can improve the effect of salt spray cleaning, thereby further reducing the corrosion of the wire rope by salt spray and further improving the service life of the wire rope and the rope drum 2.

[0034] It should be noted that a flexible membrane is fixed between the connecting plate 53 on the right side and the rotating ring 55 on the right side, which prevents the leakage of clean water used for cleaning without affecting the movement of the connecting plate 53 on the right side.

[0035] It should be noted that after cleaning is completed, the output shaft of the electric telescopic rod 9 extends, allowing the moving ring 52 to move to the left, thereby causing the ring frame 71 to move to the left. At this time, the squeezing frame 72 moves to the left along with the rotating shaft 75. The rotating shaft 75 will then stop squeezing the tilting block 73. Under the elastic force of the spring 74, the connecting plate 53, along with the cleaning frame 541 and the brush bristles 542, can move away from the wire rope. At this time, the structure used for cleaning will not come into contact with the wire rope, avoiding interference with the lubrication layer on the wire rope and thus reducing wear on the wire rope, thereby improving the service life of the winch drum and the wire rope.

[0036] It should be noted that the oil spraying assembly 8 includes an oil spraying frame fixed inside the guide frame 3. The inner side of the oil spraying frame is fixed with nozzles arranged in a ring, and lubricating oil is injected through an external pipe, so that the lubricating oil is evenly sprayed onto the wire rope, thus evenly coating the wire rope with lubricating oil.

[0037] A guide slider 56 is fixedly connected to the outer side of the rotating ring 55 on the left side. A guide groove 57 is opened on the inner side of the moving ring 52. The guide slider 56 slides inside the guide groove 57. An electric telescopic rod 9 is fixedly connected inside the guide frame 3. The output shaft of the electric telescopic rod 9 is fixedly connected to the moving ring 52. The right side of the guide groove 57 is straight, and the left side of the guide groove 57 is spiral.

[0038] By adopting the above technical solution, when the output shaft of the electric telescopic rod 9 extends, the guide slider 56 is located in the straight part of the guide groove 57. When the output shaft of the electric telescopic rod 9 needs to be cleaned and retracts, the guide slider 56 enters the spiral part of the guide groove 57.

[0039] It should be noted that when cleaning the wire rope, the output shaft of the electric telescopic rod 9 reciprocates slightly. At this time, the guide slider 56 moves inside the spiral part of the guide groove 57. This allows the rotating ring 55 on the left to rotate along with the connecting plate 53, the cleaning frame 541, and the rotating ring 55 on the right. This causes the bristles 542 to rotate slightly to clean the wire rope, ensuring the cleaning effect of the salt spray on the wire rope, further reducing the corrosion of the wire rope by the salt spray, and further improving the service life of the wire rope and the rope drum 2.

[0040] Example 2: The technical solution of this example differs from that of Example 1 in that: Figures 1 to 8 and Figures 11 to 13A sleeve 63 is fixedly connected to the front slide 61. The end of the sleeve 63 extends into the interior of the drying wheel 62, and the outer side of the sleeve 63 is rotatably connected to the drying wheel 62. The interior of the rear slide 61 is hollow. A through tube 64 is rotatably inserted into the front end of the rear slide 61, and the front end of the through tube 64 is inserted into the interior of the sleeve 63. A preheating frame 65 is fixedly connected to the rear end of the guide frame 3. The interior of the preheating frame 65 is equipped with an electric heating wire for heating air. A bent tube 66 is fixedly inserted between the preheating frame 65 and the rear slide 61. A push plate 67 is fixedly connected to the rear end of the moving ring 52 through the guide frame 3. A corrugated bladder 68 is fixedly connected between 67 and the preheating frame 65. An air inlet pipe 69 is fixedly inserted into the top of the corrugated bladder 68, and an air outlet pipe 610 is fixedly inserted into the left side of the corrugated bladder 68. Check valves 611 are installed inside both the air inlet pipe 69 and the air outlet pipe 610. The air outlet pipe 610 is inserted into the interior of the preheating frame 65. A drying cotton 612 is fixedly connected to the outside of the drying wheel 62. A drying hole 613 is opened on the drying wheel 62 near the drying cotton 612. The sleeve 63 communicates with the interior of the drying wheel 62. A bending frame 10 is fixedly connected to the connecting plate 53 at the top and bottom ends on the left side. The end of the bending frame 10 is fixedly connected to the sleeve 63.

[0041] By adopting the above technical solution, when the lubricating oil is sprayed, the residual water droplets will affect the effect of the lubricating oil adhering to the wire rope, thereby affecting the lubrication effect of the wire rope and easily aggravating the damage to the wire rope and the winding drum 2. Therefore, this solution is equipped with a drying component 6.

[0042] When the output shaft of the electric telescopic rod 9 extends, the drying wheel 62 moves away from the wire rope under the action of the bending frame 10. When the output shaft of the electric telescopic rod 9 extends, the cleaning frame 541 moves with the connecting plate 53 on the left side. At this time, the drying cotton 612 on the inside of the drying wheel 62 comes into contact with the wire rope to dry the residual water after cleaning, thereby improving the effect of lubricating oil adhering to the wire rope, thus ensuring the lubrication effect when the wire rope is wound, reducing the wear and damage of the wire rope and the drum 2, and improving the service life of the wire rope and the drum 2.

[0043] It should be noted that the drying cotton 612 is relatively thick and made of a material with high elasticity and friction. When the two drying wheels 62 approach the wire rope, the drying cotton 612 squeezes the wire rope. When the output shaft of the electric telescopic rod 9 reciprocates slightly, the drying cotton 612 always remains in contact with the wire rope.

[0044] It should be noted that when the wire rope moves, the friction between the wire rope and the wiping cotton 612 causes the wiping wheel 62 to rotate continuously, so that different positions of the wiping cotton 612 can be used for wiping, thereby improving the wiping effect.

[0045] It should be noted that, under the action of the check valve 611 inside the air outlet pipe 610, air inside the preheating frame 65 is not allowed to enter the bellows 68. Under the action of the check valve 611 inside the air inlet pipe 69, air inside the bellows 68 is not allowed to be discharged from the air inlet pipe 69. When the output shaft of the electric telescopic rod 9 reciprocates slightly, the push plate 67 can move continuously. The push plate 67 can work with the preheating frame 65 to continuously compress and stretch the bellows 68, allowing air to continuously enter the preheating frame 65. After preheating inside the preheating frame 65, the air enters the slide block 61 at the rear end through the bend 66, and then enters the inner side of the sleeve 63 through the through pipe 64. The heated air acts on the wiping cotton 612 through the drying hole 613, thereby drying the moisture on the wiping cotton 612 to ensure the drying effect of the wire rope in the future. This further improves the effect of the lubricating oil adhering to the wire rope when the lubricating oil is sprayed, ensures the lubrication effect when the wire rope is wound, reduces the wear and damage of the wire rope and the rope drum 2, and improves the service life of the wire rope and the rope drum 2.

[0046] A method for preventing clogging in domestic sewage treatment includes the following steps: S1. Position adjustment: First, unwind the wire rope, then retract it through the output shaft of the electric telescopic rod 9, which allows the moving ring 52 to move to the right, thereby causing the ring frame 71 to move to the right. At this time, the squeezing frame 72 moves to the right with the rotating shaft 75, and the rotating shaft 75 squeezes the corresponding tilting block 73. At this time, the tilting block 73 is squeezed and brings the cleaning frame 541 and brush 542 closer to the wire rope. At this time, under the action of the bending frame 10, the drying wheel 62 moves away from the wire rope. When the output shaft of the electric telescopic rod 9 extends, the cleaning frame 541 moves with the connecting plate 53 on the left side. At this time, the drying cotton 612 inside the drying wheel 62 comes into contact with the wire rope. S2. Cleaning: During the winding of the wire rope, the wire rope moves, and the bristles 542 clean the surface of the wire rope, removing the salt spray that carries the wire rope. This prevents accelerated wear on the wire rope and the winding drum 2, and improves their service life. When cleaning the wire rope, external clean water is introduced into the water inlet tank 543 through the water inlet hose 544. The clean water then enters the hollow position of the connecting plate 53 on the right side and flows into the temporal part of the cleaning frame 541. Finally, it is sprayed onto the wire rope through the spray nozzle. This simultaneous spraying of water and brushing by the bristles 542 improves the effectiveness of salt spray cleaning, further reducing the corrosion of the wire rope by salt spray and further improving the service life of the wire rope and the winding drum 2.

[0047] Working principle: When the output shaft of the electric telescopic rod 9 extends, the guide slider 56 is located in the straight section of the guide groove 57. When the output shaft of the electric telescopic rod 9 retracts for cleaning, the guide slider 56 enters the spiral section of the guide groove 57. When cleaning the wire rope, the output shaft of the electric telescopic rod 9 reciprocates slightly. At this time, the guide slider 56 moves inside the spiral section of the guide groove 57. This allows the rotating ring 55 on the left to rotate along with the connecting plate 53, the cleaning frame 541, and the rotating ring 55 on the right, thereby causing the bristles 542 to rotate slightly to clean the wire rope, ensuring the cleaning effect of the steel wire salt spray.

[0048] The drying cotton 612 is relatively thick and made of a material with high elasticity and friction. When the two drying wheels 62 approach the wire rope, the drying cotton 612 squeezes the wire rope. As the output shaft of the electric telescopic rod 9 reciprocates slightly, the drying cotton 612 remains in contact with the wire rope. During the movement of the wire rope, the friction between the wire rope and the drying cotton 612 causes the drying wheels 62 to rotate continuously, allowing different positions of the drying cotton 612 to be used for drying, thus improving the drying effect. The small reciprocating motion of the output shaft of the electric telescopic rod 9 causes the push plate 67 to move continuously. 7 can work in conjunction with the preheating frame 65 to continuously compress and stretch the bellows 68, allowing air to continuously enter the preheating frame 65. After being preheated inside the preheating frame 65, the air enters the slide block 61 at the rear end through the bend 66, and then enters the inner side of the sleeve 63 through the through pipe 64. The heated air acts on the wiping cotton 612 through the drying hole 613, thereby drying the moisture on the wiping cotton 612 to ensure the drying effect of the wire rope in the future. This further improves the effect of lubricating oil adhering to the wire rope when the lubricating oil is sprayed in the future, ensures the lubrication effect when the wire rope is wound, and reduces the wear and damage of the wire rope and the winding drum 2.

[0049] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
