Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of ship equipment, and more specifically, to an intelligent detection device for draft of an omni-rotating tugboat. Background Art
[0002] The fully revolving tugboat is a "three-high" product that provides services for large ships entering and leaving the port in the ship operation area. It integrates high power, fire fighting, towing, and pushing functions. Its biggest feature is that it can achieve 360-degree rotation in situ, with high propulsion power, large traction, flexible operation, and good stability. It is one of the two necessary machines for port development. As the port's requirements for intelligence gradually increase, the degree of fully revolving intelligence is getting higher and higher.
[0003] As domestic ports have higher requirements for intelligence, the requirements for ship automation have also increased. Traditional full-revolving tugboats are generally not equipped with ship draft because of their relatively small main dimensions. Generally, they only use the water gauge required by ship regulations to record the water level of the water gauge from the outer plate to judge the floating state of the full-revolving tugboat. However, this traditional method cannot meet the requirements of full-revolving tugboat automation and intelligence. Existing full-revolving tugboats usually have draft sensors FR25 in the empty compartment in the middle of the ship. ～ FR26 (mid-section draft sensor) is an outer plate opened on the draft seat plate at the bottom of the ship to connect the draft sea valve. A short pipe is arranged behind the draft sea valve. The short pipe is provided with a draft vent to discharge the air collected at the draft. The short pipe temperature sensor is used to detect the seawater temperature. The draft sensor is installed behind the short pipe to intelligently detect the draft depth of the ship.
[0004] Since the sea valve is submerged in seawater for a long time, marine attachments such as marine organisms in the seawater (such as oysters) or garbage in the incoming seawater are easy to attach to the sea valve, causing the sea valve to be blocked, which in turn affects the ship's draft depth detection, significantly reduces the accuracy of the ship's draft depth detection, affects the ship's navigation safety, significantly increases the ship's maintenance time, and reduces the attendance rate of the full-turn tugboat.

In addition, the character " / " in this article generally indicates that the previous and next associated objects are in an "or" relationship.
[0038] according to Figure 1-Figure 13As shown, an intelligent draft detection device for an omni-rotating tugboat includes a draft depth detection component and a debris removal component, wherein the draft depth detection component is arranged on the bottom surface of the hull, and the debris removal component is arranged on the draft depth detection component. The draft depth detection component includes a sea valve 1, a seawater guide component and a draft detection component, wherein the sea valve 1 is arranged on the bottom surface of the hull, the seawater guide component is arranged on the sea valve 1, and the draft detection component is arranged on the seawater guide component.
[0039] The side of the shell of the sea valve 1 is provided with a mounting seat 2, and the free end of the mounting seat 2 is sealed and installed on the hull outer plate 3 at the bottom of the hull. It should be noted that the mounting seat 2 is subjected to high-pressure sealing treatment at the penetration point on the hull outer plate 3 to prevent seawater from penetrating into the hull through the penetration point. As an option, the opening and closing mode of the sea valve 1 can be manual or automatic by a motor according to needs.
[0040] The seawater guide member includes a draft short pipe 4, a vent short branch pipe 5, a vent valve and a temperature sensor. The draft short pipe 4 is connected to the second flange on the water outlet of the sea valve 1 through a first flange at one end. One end of the vent short branch pipe 5 passes through the side wall of the draft short pipe 4. The vent valve is installed on the free end of the vent short branch pipe 5 to discharge the air in the draft short pipe 4. The temperature sensor is installed on the inner wall of the draft short pipe 4 to detect the temperature of the seawater entering the draft short pipe 4 in real time.
[0041] The draft detection component includes an anti-impact plate 7, a maintenance ball valve 8 and a draft sensor 9. One end of the anti-impact plate 7 is fastened to the third flange on the other end of the draft short pipe 4 by bolts, and one end face of the maintenance ball valve 8 is also fastened to the other end of the anti-impact plate 7 by the bolts. The draft sensor 9 is also fastened to the other end face of the maintenance ball valve 8 by the bolts.
[0042] It should be noted that seawater enters through the water inlet of the sea valve 1, then enters the draft short pipe 4 through the water outlet of the sea valve 1, and then contacts the draft sensor 9 through the anti-impact plate 7 and the inspection ball valve 8 in turn to detect the draft depth of the full-revolving tugboat.
[0043] The debris removal component includes a debris filter, a debris cutter and a debris purge component. The debris filter is arranged on the sea valve 1, the debris cutter is arranged on the debris filter, and the debris purge component is arranged on the debris cutter. The debris filter component includes a seawater relay pipe 10 and a seawater filter 11. One end of the seawater relay pipe 10 is through-fastened to the water inlet of the sea valve 1. The seawater filter 11 is externally fixed with a fourth flange. The seawater filter 11 is fastened to the other end of the seawater relay pipe 10 through the fourth flange. It should be noted that seawater enters the seawater relay pipe 10 through the seawater filter 11, and then enters the sea valve 1. The seawater filter 11 can filter aquatic organisms or garbage in the seawater to enter the sea valve 1.
[0044] The debris removal part includes a removal transmission part, a removal power part and a debris removal part. The removal transmission part is arranged on the debris filter part. The removal power part and the debris removal part are both arranged on the removal transmission part. The removal transmission part includes a removal support frame 12 and a removal transmission shaft 13. The removal support frame 12 is arranged on the inner wall of one end of the seawater relay pipe 10 to provide support for the removal transmission shaft 13. One end of the removal transmission shaft 13 is horizontally rotatably embedded in the rotation support sleeve 14 of the removal support frame 12, and the axis of the removal transmission shaft 13 coincides with the axis of the seawater relay pipe 10, so that the removal transmission shaft 13 can be circumferentially rotated and axially locked on the removal support frame 12.
[0045] The cutting power member includes a first cutting power member and a second cutting power member, and the first cutting power member and the second cutting power member are both arranged on the cutting transmission member. The first cutting power member includes a fan blade 15, a protective shell 16 and a ventilation nozzle 17. One end of the fan blade 15 is fixedly arranged on the side wall of the cutting transmission shaft 13. The fan blade 15 is provided with eight, and the eight fan blades 15 are evenly distributed around the cutting transmission shaft 13. The protective shell 16 is tubular, and the inner diameter of the protective shell 16 is greater than the length of the fan blade 15. The protective shell 16 is fixedly arranged on the inner wall of the seawater relay pipe 10 through the supporting legs 25. The axis of the protective shell 16 coincides with the axis of the seawater relay pipe 10, and the protective shell 16 is sleeved outside the fan blade 15. At the same time, the rotating through hole on one end face of the protective shell 16 is rotatingly sealed and sleeved outside the cutting transmission shaft 13. The diameter of the exhaust through hole on the other end face of the protective shell 16 is greater than the diameter of the cutting transmission shaft 13. The vent nozzle 17 is tubular, one end of which passes through the side wall of the seawater relay pipe 10 and is connected to the protective shell 16, and the axis of the vent nozzle 17 is parallel to the tangent of the protective shell 16. When the high-pressure gas enters the protective shell 16 through the vent nozzle 17, it will push the fan blade 15 to rotate, and the rotating fan blade 15 will drive the cutting transmission shaft 13 to rotate.
[0046] The second cutting power member includes a power transmission groove 18 and a jet nozzle 19. The power transmission groove 18 is in the shape of a circular groove. The power transmission groove 18 is fixedly mounted on the cutting transmission shaft 13 through the transmission through hole on the bottom surface of the groove, and the axis of the power transmission groove 18 coincides with the axis of the protective shell 16. At the same time, the side wall of the slot of the power transmission groove 18 is rotationally sealed and embedded in the rotating groove on the other end surface of the protective shell 16. The rotating groove is in the shape of an annular groove. One end of the jet nozzle 19 is connected to the side wall of the power transmission groove 18, and the axis of the jet nozzle 19 is parallel to the tangent of the power transmission groove 18. There are four jet nozzles 19, and the four jet nozzles 19 are evenly distributed around the power transmission groove 18. It should be noted that after the high-pressure gas enters the power transmission groove 18 through the exhaust through hole, the jet nozzle 19 is ejected at a high speed, thereby driving the power transmission groove 18 to rotate, and the rotating power transmission groove 18 drives the cutting transmission shaft 13 to rotate. The cutting transmission shaft 13 is provided with rotational power by dual power of the first cutting power member and the second cutting power member.
[0047] The debris removal part includes a removal transmission tube 20, a magnetic coil 21 and a debris removal knife 22. One end of the removal transmission tube 20 is sleeved on the other end of the removal transmission shaft 13, and the slider on the inner wall of the removal transmission tube 20 is fitted into the slide groove on the other end of the removal transmission shaft 13. The other end of the removal transmission tube 20 rotates through the removal through hole at the center of the seawater filter 11. The removal transmission tube 20 is circumferentially locked and axially slid on the removal transmission shaft 13. The magnetic coil 21 is fixedly fitted into the spiral groove on the inner wall of the removal transmission tube 20. One end of the debris removal knife 22 is vertically fixedly arranged on the outer wall of the other end of the removal transmission tube 20, and the two debris removal knives 22 are evenly distributed around the removal transmission tube 20.
[0048] Before the high-pressure gas is introduced into the ventilation nozzle 17, when the positive direct current is introduced into the magnetic coil 21 to generate a magnetic field, the cutting transmission tube 20 is pushed to slide outward, and then the cutting transmission tube 20 drives the debris cutting knife 22 away from the seawater filter 11. At this time, the high-pressure gas is introduced into the ventilation nozzle 17 to drive the cutting transmission shaft 13 to rotate, and then drive the debris cutting knife 22 to rotate. After the debris cutting knife 22 rotates stably, when the reverse direct current is introduced into the magnetic coil 21 to generate a magnetic field, the debris cutting knife 22 that rotates stably and at a high speed is driven by the cutting transmission tube 20 to rotate and fit on the seawater filter 11, so as to cut and detach the debris attached to the seawater filter 11. The debris that is cut and detached is swept outward again by the high-pressure gas sprayed by the injection nozzle 19, which significantly improves the cleaning efficiency and cleaning quality of the attached debris. It should be noted that before the debris is cleaned, the sea valve 1 is in a closed state.
[0049] The debris purge component includes a high-pressure relay pipe 23, one end of which is connected to the other end of the ventilation nozzle 17, and the other end of which is connected to one end of a high-pressure through hole 24 on the side wall of the mounting seat 2. The other end of the high-pressure through hole 24 is connected to the free end surface of the mounting seat 2, that is, the other end of the high-pressure through hole 24 is connected to the hull of the full-revolving tugboat. The other end of the high-pressure through hole 24 is connected to the high-pressure air supply equipment through a high-pressure pipe. It should be noted that the high-pressure air supply equipment sprays high-pressure gas into the protective shell 16 through the high-pressure pipe, the high-pressure through hole 24, the high-pressure relay pipe 23 and the ventilation nozzle 17, thereby driving the fan blades 15 to rotate.
