DETAILED DESCRIPTION

[0030] The technical solution of the present invention will be clearly and completely described below in conjunction with the embodiments. Obviously, the described embodiments are part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0031] As described in the background technology, during the use of anchor ropes, debris in the water will move with the water flow and easily adhere to the anchor ropes when encountering them. The accumulation of debris will continue to increase, causing the ship to rotate in the water, increasing the water surface, and causing the ship to sink in serious cases. Therefore, how to prevent debris in the water from adhering to the anchor rope has become a technical problem that needs to be solved urgently by those skilled in the art.

[0032] To solve the above problems, refer to Figure 1 and Figure 2The present invention provides a device for preventing underwater debris from being attached to an anchor rope, comprising a first rotating shaft 110, a second rotating shaft 120, a crawler 130 and a debris capturing member 140. The first rotating shaft 110 is formed with an anchor rope passing hole for the anchor rope 200 to pass through along the axial direction. The axis of the second rotating shaft 120 is parallel to the axis of the first rotating shaft 110. The crawler 130 is wound around the first rotating shaft 110 and the second rotating shaft 120. The first rotating shaft 110 and the second rotating shaft 120 can rotate to drive the crawler 130 to rotate around the first rotating shaft 110 and the second rotating shaft 120. Water flows through the opposite outer sides of the crawler 130. A clearance hole 131 is opened on the crawler 130. The debris capturing member 140 is installed on the inner circumference of the crawler 130. When the crawler 130 passes around the first rotating shaft 110, the first rotating shaft 110 acts on the debris capturing member 140, causing the debris capturing member 140 to protrude from the clearance hole 131 to capture the debris in the water. When the crawler 130 passes around the first rotating shaft 110, the debris capturing member 140 retracts to the inner side of the crawler 130, causing the debris in the water to separate from the debris capturing member 140 and move along the outer side of the crawler 130 to separate from the device for preventing the debris in the water from being attached to the anchor rope. In this way, it is possible to effectively prevent the debris in the water from being attached to the anchor rope 200, avoid a large amount of debris from accumulating on the anchor rope 200, and eliminate the risk of sinking.

[0033] Specifically, in the exemplary embodiment, the debris capture member 140 is a spring sheet, one end of which is bent to form a hook. When the track 130 passes around the first rotating shaft 110, the outer wall of the first rotating shaft 110 squeezes the debris capture member 140, causing the debris capture member 140 to deform, and the hook is extended out of the clearance hole 131 to hook the debris in the water. When the track 130 passes around the first rotating shaft 110, the debris capture member 140 is no longer squeezed, and the deformation is restored spontaneously, and the hook is retracted to the inner side of the track 130, so that the debris in the water is separated from the hook. Compared with the rigid debris capture member 140, it has a certain elastic deformation ability, can absorb and reduce external impact, vibration and torque, and extend its service life.

[0034] Preferably, there are a plurality of clearance holes 131, which are evenly distributed along the circumference and axial direction of the crawler 130. There are a plurality of debris capture members 140, which are evenly distributed along the circumference and axial direction of the crawler 130, and correspond one to one with the plurality of clearance holes 131. In this way, the debris capture capability is further improved, thereby more effectively preventing the attachment of underwater debris to the anchor rope 200.

[0035] Preferably, an avoidance groove 121 is provided on the side wall of the second rotating shaft 120 along the circumferential direction. There are a plurality of avoidance grooves 121, which are evenly distributed along the axial direction of the second rotating shaft 120. When the track 130 passes around the second rotating shaft 120, the debris capture member 140 can be received in the avoidance groove 121, so as to prevent the side wall of the second rotating shaft 120 from squeezing the debris capture member 140, thereby facilitating the extension of the service life of the debris capture member 140.

[0036] In some practical applications, the debris capture member 140 is detachably connected to the crawler 130. Specifically, the debris capture member 140 can be installed on the crawler 130 by screws or rivets. A screw clearance groove or a rivet clearance groove is opened along the circumferential direction on the side wall of the first rotating shaft 110. There are multiple screw clearance grooves or rivet clearance grooves, which are evenly distributed along the axial direction of the first rotating shaft 110.

[0037] In other practical applications, the debris capture member 140 is non-detachably connected to the crawler 130. Specifically, the debris capture member 140 is welded or bonded to the crawler 130.

[0038] In some practical applications, a transmission chain 132 is provided at one end of the crawler 130, and correspondingly, a sprocket is sleeved at one end of the first rotating shaft 110 and the second rotating shaft 120. The transmission is performed through the sprocket and the transmission chain 132. The chain transmission form is simple in structure and high in transmission efficiency.

[0039] In other practical applications, transmission chains 132 are respectively provided at opposite ends of the crawler 130, and correspondingly, sprockets are respectively provided at opposite ends of the first rotating shaft 110 and the second rotating shaft 120. In this way, power can be transmitted in a coordinated manner, and the service life thereof can be extended.

[0040] In some practical applications, a transmission belt is provided at at least one end of the crawler belt 130, and correspondingly, a pulley is provided at at least one end of the first rotating shaft 110 and the second rotating shaft 120. The transmission is performed through the pulley and the transmission belt. The belt transmission form has a simple structure, good mute effect, and does not require lubrication.

[0041] Preferably, end covers are respectively installed at opposite ends of the crawler track 130 to form a sealed cavity inside the crawler track 130, which is beneficial to prolonging the service life of the transmission mechanism.

[0042] Preferably, there are two or more devices for preventing water debris from adhering to the anchor rope, which are arranged in sequence along the extension direction of the anchor rope 200. In this way, the size of a single device can be reduced and the energy consumption required for operation can be reduced.

[0043] Preferably, the device for preventing underwater debris from attaching to the anchor rope also includes a buoyancy adjustment block, which is installed in the cavity surrounded by the track and is used to adjust the buoyancy of the device for preventing underwater debris from attaching to the anchor rope as a whole, so that the buoyancy of the device for preventing underwater debris from attaching to the anchor rope is equal to its own gravity, and the device has no tendency to float or sink, thereby avoiding the device for preventing underwater debris from attaching to the anchor rope from applying gravity to the anchor rope.

[0044] In some practical applications, the device for preventing the attachment of underwater debris to the anchor rope also includes an isolation cover, a first transmission shaft, a second transmission shaft and a driving blade 150. The isolation cover is fixedly mounted on one end of the second rotating shaft 120 / the first rotating shaft 110. A first transmission gear is sleeved on the second rotating shaft 120 / the first rotating shaft 110. The first transmission shaft is installed in the isolation cover and forms a certain angle with the second rotating shaft 120 / the first rotating shaft 110. A second transmission gear meshingly connected to the first transmission gear is sleeved on the first transmission shaft. The axis of the driving blade 150 forms a certain angle with the second rotating shaft 120. One end of the second transmission shaft is fixedly connected to one end of the driving blade 150, and the other end is detachably connected to one end of the first transmission shaft, so that one end of the driving blade 150 can be connected or disconnected with one end of the second rotating shaft 120 / the first rotating shaft 110. When one end of the driving blade 150 is in transmission connection with one end of the second rotating shaft 120 / the first rotating shaft 110, the driving blade 150 can rotate with the help of water flow, thereby driving the second rotating shaft 120 / the first rotating shaft 110 to rotate, thereby driving the crawler 130 to rotate around the first rotating shaft 110 and the second rotating shaft 120. The passive driving method is adopted, which greatly saves energy.

[0045] In other practical applications, the device for preventing the attachment of underwater debris to the anchor rope further includes a rotary driver 170. The rotary driver 170 is detachably mounted in the sealed chamber. A first transmission gear is sleeved on the output shaft of the rotary driver 170. A second transmission gear is sleeved on one end of the second rotating shaft 120 / first rotating shaft 110. The second transmission gear and the first transmission gear can be meshed and connected or disconnected, so that the output shaft of the rotary driver 170 can be transmission-connected or disconnected with one end of the second rotating shaft 120 / first rotating shaft 110. When the output shaft of the rotary driver 170 is transmission-connected with one end of the second rotating shaft 120 / first rotating shaft 110, the second rotating shaft 120 / first rotating shaft 110 can be driven to rotate, thereby driving the crawler 130 to rotate around the first rotating shaft 110 and the second rotating shaft 120. The active drive mode is adopted to ensure the stability of the prevention effect.

[0046] In some practical applications, the device for preventing the attachment of debris in the water to the anchor rope also includes an isolation cover, a first transmission shaft, a second transmission shaft, a driving blade 150 and a rotary driver 170. The isolation cover is fixedly mounted on one end of the second rotating shaft 120 / the first rotating shaft 110. The second rotating shaft 120 / the first rotating shaft 110 is sleeved with a first transmission gear. The first transmission shaft is installed in the isolation cover and forms a certain angle with the second rotating shaft 120 / the first rotating shaft 110. A clutch is sleeved on the first transmission shaft, and a second transmission gear is disposed on the clutch outer sleeve, and the second transmission gear is meshed and connected with the first transmission gear. The axis of the driving blade 150 forms a certain angle with the second rotating shaft 120. One end of the second transmission shaft is fixedly connected to one end of the driving blade 150, and the other end is connected to one end of the first transmission shaft. The clutch can connect or disconnect the second transmission gear with the first transmission shaft, so that one end of the driving blade 150 is connected or disconnected with one end of the second rotating shaft 120 / the first rotating shaft 110. The rotary driver 170 is fixedly installed in the sealed cavity. A clutch is sleeved on the output shaft of the rotary driver 170, and a first transmission gear is sleeved on the clutch outer cover. A second transmission gear is sleeved on one end of the second rotating shaft 120 / first rotating shaft 110. The second transmission gear is meshed and connected with the first transmission gear. The clutch can connect or disconnect the first transmission gear with the output shaft of the rotary driver 170, so that the output shaft of the rotary driver 170 can be connected or disconnected with one end of the second rotating shaft 120 / first rotating shaft 110. In this way, both an active driving mode and a passive driving mode can be adopted, and a driving mode combining active and passive modes can also be adopted.

[0047] It should be noted that the second rotating shaft 120 can be selected as the active rotating shaft, and the first rotating shaft 110 can be selected as the driven rotating shaft, so as to facilitate the connection between the driving source and the rotating shaft. Of course, the first rotating shaft 110 can also be selected as the active rotating shaft, and the second rotating shaft 120 can be selected as the driven rotating shaft to ensure that the first rotating shaft 110 has sufficient power, thereby ensuring the preventive effect.

[0048] Preferably, the rotary driver 170 may be a servo motor with high control accuracy or a stepper motor with low cost.

[0049] It should be noted that when a passive driving method is adopted, the device for preventing water debris from adhering to the anchor rope further includes a float 160. The float 160 is installed at one end of the driving blade 150 away from the second rotating shaft 120, and can prevent the driving blade 150 from spontaneously sinking.

[0050] On the other hand, the present invention also provides a ship mooring system, characterized in that it includes a device for preventing water debris from being attached to an anchor rope, an anchor stone and an anchor rope 200. The anchor stone is placed on the bottom of the water. One end of the anchor rope 200 is fixedly connected to the anchor stone, and the other end passes through the anchor rope passing hole of the first rotating shaft 110 of the device for preventing water debris from being attached to the anchor rope and is connected to a ship floating on the water surface to prevent the ship from being washed away by the water flow. When the crawler 130 passes around the first rotating shaft 110, the first rotating shaft 110 acts on the debris capture member 140, so that the debris capture member 140 protrudes out of the clearance hole 131 to capture water debris. When the crawler 130 passes around the first rotating shaft 110, the debris capture member 140 retracts to the inner side of the crawler 130, so that the water debris is separated from the debris capture member 140, and moves along the outer side of the crawler 130 to separate from the device for preventing water debris from being attached to the anchor rope. In this way, it is possible to effectively prevent debris in the water from being attached to the anchor rope 200, avoid a large amount of debris from accumulating on the anchor rope 200, and eliminate the risk of shipwreck.
