Abstract

The application discloses an intelligent ship guiding system for a dock, which comprises a ship parking bin, a dock gate arranged outside the ship parking bin, and a concrete base arranged at the bottom of the ship parking bin. In the application, a power assembly is arranged. During the process of pulling a ship into the ship parking bin, the power assembly drives the rotating rod and the propeller to rotate, so that the water flow in the ship parking bin flows into the ship parking bin, flows out through the through groove, and can drive the ship to move. Compared with the traditional method of pulling the ship by a pulling rope, the application avoids the breakage of the pulling rope caused by the pulling force of the pulling rope, reduces the occurrence of safety accidents, and enables the ship to be kept on the center line of the ship parking bin during the process of pulling the ship by the traction vehicle, so that the ship is prevented from deviating during the pulling process and from colliding with the water retaining wall to cause damage to the water retaining wall or the ship.

Description

Technical Field

[0001] This invention relates to the field of shipbuilding technology, and in particular to an intelligent dock tugboat system. Background Technology

[0002] A dock is a dock-like structure used for shipbuilding and repair. When flooded, it allows ships to enter and exit; when dewatered, it allows for shipbuilding and repair on a dry bottom. Docks can be divided into three categories: dry docks, flooded docks, and floating docks. Dry docks are the most commonly used, and the term "dock" generally refers to a dry dock. Docks evolved from the initial "ship pits." On tidal coasts, people used the rise and fall of water levels to raise and lower ships. At high tide, ships were led into a "ship pit" surrounded on three sides by earthen dikes. At low tide, the ships sat on pre-set supports, and the opening was sealed with embankments for repair work. When the ships were to leave the pit, the embankments were removed, and they were allowed to leave at high tide. Later, the earthen dikes were replaced with dock walls, and the embankments with dock gates. Water pumps were used to control the rise and fall of the water level inside the dock, gradually evolving into dry docks. Dry docks are connected to land on three sides and face water on one side. Their basic components are the dock entrance, dock chamber, and dock bow. The dock entrance is used for ships to enter and exit, and is equipped with a sluice gate. The dock's flood control and drainage equipment is typically built into the dock piers on either side of the entrance. The dock chamber is used to house ships, and its floor has keel piers and side piers for support. The bow is the end opposite the dock entrance, and its plan shape can be rectangular, semi-circular, or rhomboid. The space at the bow is part of the dock chamber, where propellers and stern shafts are installed and removed. Dry docks are equipped with various power pipelines and auxiliary equipment such as hoisting, rust removal, painting, and ship towing facilities. When a ship enters the dry dock for repairs, it is first filled with water using flood control facilities. Once the water level inside and outside the dock is equal, the dock gate is opened, and the ship is slowly towed into the dock using towing equipment. Afterward, the water is pumped out, allowing the ship to rest on the keel piers. When a ship is to leave the dry dock after repairs or construction, it is first filled with water until the water level inside and outside the dock gate is equal, then the gate is opened, and the ship is towed out.

[0003] Because the space inside a dock is small when a ship approaches, the ship's power unit is shut off. Therefore, when a ship enters a dock, it is usually towed into the dock by a tugboat. During this process, the towing rope is subjected to great pressure and may crack or break during use, causing a safety accident. Currently, some docks use winches or winches to move the ship. However, winches or winches may cause the ship to tilt and deviate during the pulling process, causing the ship to touch the edge of the dock. In addition, multiple manual interventions are required during the docking process, which increases the labor intensity of the staff. Summary of the Invention

[0004] The purpose of this invention is to solve the problems in the background technology where the towing rope is subjected to great pressure and may crack or break during use, causing safety accidents. Currently, some docks are driven by winches or winches, but the winches or winches may cause the ship to tilt and deviate during the process of pulling the ship, causing the ship to touch the edge of the dock. In addition, multiple manual interventions are required during the docking process, which increases the labor intensity of the workers. Therefore, an intelligent dock ship traction system is proposed.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: an intelligent dock traction system, including a berthing bay, a dock gate on the outside of the berthing bay, a concrete base at the bottom of the berthing bay, water-retaining walls fixedly connected to both sides of the concrete base, the water-retaining walls being symmetrically arranged along the concrete base, a sliding rail fixedly connected to the top of each of the two water-retaining walls, a tractor slidably connected to the sliding rail, a winch fixedly installed at the land-facing end of the top of the water-retaining wall, the winch being used to drive the tractor slid on the sliding rail, a guide channel being formed on the opposite sidewalls of the two water-retaining walls, a rotating rod being provided in the guide channel, multiple propellers being sleeved on the rotating rod, a power assembly being fixedly installed on the sidewall of the berthing bay, the power assembly being used to drive the rotating rod to rotate, a through groove being formed at the land-facing end of the sidewall of the guide channel, an opening and closing assembly being provided at the top of the through groove, a laser emitter and a laser signal receiver being fixedly installed on the opposite sidewalls of the two water-retaining walls, the laser emitted by the laser emitter being received by the laser signal receiver.

[0006] Preferably, the dock gate is a floating dock gate with a built-in pump. When the vessel is towed into the berth, water can be added to the dock gate to block the berth and prevent water from entering. When it is necessary to leave the berth, the pump inside the dock gate can be used to pump out the water, causing the dock gate to float. Then, the dock gate can be towed away, allowing water to enter the berth and the vessel to leave.

[0007] Preferably, the tractor and the winch are connected by a steel wire rope. A high-strength mooring cable is fixedly connected to the tractor. The steel wire rope ensures a stable connection between the winch and the tractor. When guiding the ship into the berth, the operator can tie the end of the high-strength mooring cable to two symmetrical positions at both ends of the ship's deck. The winch drives the tractor, which in turn pulls the ship through the high-strength mooring cable, towing the ship into the berth. Since the two high-strength mooring cables are of the same material and length, and their connections to the ship are symmetrical, the ship can be towed to the center of the berth without touching the retaining wall.

[0008] Preferably, a reinforcing plate is fixedly connected to the bottom of the sliding rail, and the reinforcing plate is embedded inside the retaining wall. Limiting plates are provided on both sides of the bottom of the tractor, and the limiting plates are slidably connected to the bottom of the sliding rail. Multiple rolling wheels are provided at the bottom of the limiting plates, and the rolling wheels can slide on the surface of the retaining wall. The retaining wall is made of concrete. By setting the reinforcing plate, the sliding rail can be kept stable. When towing the ship, the sliding rail will not loosen from the retaining wall due to excessive pulling force of the tractor, thus increasing the overall service life. The presence of the limiting plate and the rolling wheels allows the tractor to maintain a straight movement along the direction of the sliding rail, preventing the ship from deviating from the center of the berth.

[0009] Preferably, the inner edge of the guide channel is provided with multiple load-bearing columns, and multiple isolation rods are fixedly connected in the gaps between the load-bearing columns. The isolation rods are arranged vertically in the gaps between the load-bearing columns, and the distance between two adjacent isolation rods is 30mm. The load-bearing columns can maintain the stability of the water retaining wall and will not deform due to the large tonnage of the ship. By setting up the isolation rods, large fish or other organisms in the water can be prevented from entering the guide channel and damaging the propeller in the guide channel, thus preventing the propeller from getting stuck.

[0010] Preferably, mounting seats are symmetrically arranged inside the flow guide channel. The mounting seats are rotatably penetrated by the rotating rod, and one end of the rotating rod rotatably penetrates the side wall of the flow guide channel. The mounting seats provide stable support, which allows the rotating rod and the propeller to rotate stably.

[0011] Preferably, the power assembly includes a motor, and a first pulley, a second pulley, and a transmission belt symmetrically arranged along the output end of the motor. The motor is fixedly mounted on the side wall of the berthing hold. The first pulley is fixedly sleeved on the output end of the motor, and the second pulley is fixedly sleeved on the end of the rotating rod located outside the guide channel. The transmission belt is sleeved on the same set of first and second pulleys. The motor drives the first pulley to rotate, which in turn drives the second pulley to rotate via the transmission belt. This causes the second pulley to drive the rotating rod and the propeller to rotate, thereby causing the water in the guide channel and the berthing hold to flow from the outside to the inside. During the towing process, this can move the ship, reducing the tension on the towing vehicle. Compared to the traditional method of pulling the ship solely with a towing rope, this reduces the possibility of towing rope breakage, thus reducing the occurrence of safety accidents.

[0012] Preferably, the opening and closing assembly includes a waterstop plate, a support frame, and an electric cylinder symmetrically arranged along the berthing hold. The waterstop plate is inserted into the water-retaining wall and can block the through channel. The support frame is fixedly installed on the water-retaining wall, and the electric cylinder is fixedly installed on the support frame, with its end fixedly connected to the top of the waterstop plate. Before the ship is guided to the berthing hold, the through channel is opened by the opening and closing assembly, and the dock door is pulled away, allowing water to quickly enter the berthing hold. When the ship is berthed, the dock door is closed, the through channel is blocked by the opening and closing assembly, and then the water in the berthing hold is pumped out by relevant equipment to prevent water from entering the berthing hold during ship maintenance.

[0013] Preferably, a drainage groove is provided at the edge of the concrete base, and high-pressure water pumps are fixedly installed on the two water-retaining walls respectively. The inlet end of the high-pressure water pump is fixedly connected to an inlet pipe, the bottom end of which is located in the drainage groove. The outlet end of the high-pressure water pump is fixedly connected to a drain pipe, which is a flexible hose. When the ship enters the berth and the berth is closed, the water in the berth can be quickly pumped out by the high-pressure water pump, so that the ship stops in the berth as the water level drops, facilitating subsequent maintenance and repair of the ship by the staff.

[0014] Preferably, a control console is also fixedly installed on the water retaining wall. The control console is electrically connected to the winch, the laser signal collector, the motor, the electric cylinder, and the high-pressure water pump, respectively. It can be used to control the operation of each electrical device and can be operated in both manual and automatic modes.

[0015] Compared with the prior art, the advantages and positive effects of the present invention are as follows:

[0016] 1. In this invention, by setting up a power component, during the process of towing the ship into the berth, the power component drives the rotating rod and propeller to rotate, causing the water in the berth to flow into the berth and out through the channel. This allows the water in the berth to drive the ship's movement. Compared with the traditional method of towing the ship with a tow rope, this avoids the ship relying solely on the tension of the tow rope, which could lead to the tow rope breaking and reduces the occurrence of safety accidents.

[0017] 2. In this invention, the symmetrically arranged sliding rails, winches, and tractor enable the tractor to keep the ship on the center line of the berth during the towing process, preventing the ship from deviating during towing and thus avoiding the ship from touching the water barrier and causing damage to the water barrier or the ship.

[0018] 3. In this invention, by setting up a laser transmitter and a laser signal receiver, the laser emitted by the laser transmitter is blocked when the ship is fully inside the berth, and the signal received by the laser signal receiver is changed. As a result, the laser signal receiver feeds the signal back to the control console, which then automatically controls the operating status of various electrical devices, making the system more intelligent and reducing the labor intensity of the staff.

[0028] To better understand the above-mentioned objectives, features, and advantages of the present invention, the present invention will be further described below in conjunction with the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0029] Numerous specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways than those described herein, and therefore the invention is not limited to the specific embodiments disclosed in the following specification.

[0030] like Figures 1-7 As shown, this invention provides an intelligent docking system for guiding ships, including a berthing bay 1, a dock gate 2 on the outside of the berthing bay 1, a concrete base 3 at the bottom of the berthing bay 1, and water-retaining walls 4 fixedly connected to both sides of the concrete base 3. The water-retaining walls 4 are symmetrically arranged along the concrete base 3, and a sliding rail 5 is fixedly connected to the top of each of the two water-retaining walls 4. A tractor 6 is slidably connected to the sliding rail 5. A winch 7 is fixedly installed at the end of the top of the water-retaining wall 4 near the land, and the winch 7 is used to drive the tractor 6 to slide on the sliding rail 5. A guide channel 8 is opened on the opposite side wall of each of the two water-retaining walls 4, and a rotating rod 9 is provided in the guide channel 8. Multiple propellers 10 are sleeved on the rotating rod 9. A power assembly 11 is fixedly installed on the side wall of the berthing bay 1, and the power assembly 11 is used to drive the rotating rod 9 to rotate. A through channel 12 is opened at the end of the side wall of the guide channel 8 near the land, and an opening and closing assembly 13 is provided at the top of the through channel 12. The two water-retaining walls have corresponding openings on their opposite side walls. A laser emitter 14 and a laser signal receiver 15 are fixedly installed. The laser emitted by the laser emitter 14 can be received by the laser signal receiver 15. In some embodiments, by setting a power component 11, during the process of towing the ship into the berthing compartment 1, the power component 11 drives the rotating rod 9 and the propeller 10 to rotate, so that the water in the berthing compartment 1 flows into the interior of the berthing compartment 1 and flows out from the through channel 12, so that the water in the berthing compartment 1 can drive the ship to move. Compared with the traditional method of dragging the ship with a tow rope, this avoids the ship relying solely on the tension of the tow rope to pull it, which could lead to the tow rope breaking, thus reducing the occurrence of safety accidents. Through the symmetrically arranged sliding rail 5, winch 7 and tractor 6, the ship can be kept on the center line of the berthing compartment 1 during the towing process, preventing the ship from deviating during the towing process, thereby preventing the ship from touching the water retaining wall 4 and causing damage to the water retaining wall 4 or the ship.

[0031] The working principle here is as follows: When the ship is towed into the berth 1, the workers tow the dock gate 2 (the dock gate 2 is a floating dock gate 2, which has a built-in pump. When the ship is towed into the berth 1, water can be added to the dock gate 2 to block the berth 1 and prevent water from entering the berth 1. When it is necessary to sail the ship out of the berth 1, the pump inside the dock gate 2 can be used to pump out the water inside the dock gate 2 to make the dock gate 2 float, and then the dock gate 2 can be towed away, allowing water to enter the berth 1 and the ship to sail out of the berth 1). The opening and closing component 13 controls the passage 12 to open, allowing water to enter the berth 1. Then, the two symmetrical positions on the ship's deck are connected to the towing vehicle 6. The two tractors are connected, and then the winch 7 drives the tractor 6. At this time, the power unit 11 drives the rotating rod 9 and the propeller 10 to rotate, thereby driving the water flow. The water flows into the berthing chamber 1 and is discharged through the channel 12. The flowing water drives the ship into the berthing chamber 1, avoiding the ship relying solely on the tractor 6 to pull it, which could lead to the towing rope breaking and reduce the occurrence of safety accidents. Furthermore, since the two tractors 6 are symmetrically positioned and the connection points between the two tractors 6 and the ship are symmetrical, the ship is always located on the center line of the berthing chamber 1 when it is being towed into the berthing chamber 1, avoiding the ship from touching the water retaining walls 4 on both sides, thus protecting the ship and the water retaining walls 4.

[0032] like Figure 1 , Figure 2 As shown, in some embodiments, the tractor 6 and the winch 7 are connected by a steel wire rope 16. A high-strength mooring cable 17 is fixedly connected to the tractor 6. The steel wire rope 16 can ensure a stable connection between the winch 7 and the tractor 6. When the ship is brought into the berth 1, the workers can tie the end of the high-strength mooring cable 17 to two symmetrical positions at both ends of the ship's deck. The winch 7 drives the tractor 6, and the tractor 6 drives the ship through the high-strength mooring cable 17, dragging the ship into the berth 1. Since the two high-strength mooring cables 17 are of the same material and length and their connection points with the ship are symmetrical, the ship can be dragged to the center of the berth 1 without touching the water-retaining wall 4.

[0033] like Figure 1 , Figure 4 , Figure 5As shown, in some embodiments, a reinforcing plate 18 is fixedly connected to the bottom of the sliding rail 5. The reinforcing plate 18 is embedded inside the retaining wall 4. Limiting plates 19 are provided on both sides of the bottom of the tractor 6. The limiting plates 19 are slidably connected to the bottom of the sliding rail 5. Multiple rolling wheels 20 are provided at the bottom of the limiting plates 19. The rolling wheels 20 can slide on the surface of the retaining wall 4. The retaining wall 4 is made of concrete. By setting the reinforcing plate 18, the sliding rail 5 can remain stable. When towing the ship, the sliding rail 5 will not loosen from the retaining wall 4 due to excessive pulling force of the tractor 6, thus increasing the overall service life. The presence of the limiting plate 19 and the rolling wheels 20 allows the tractor 6 to maintain a straight movement along the direction of the sliding rail 5, preventing the ship from deviating from the center of the berthing compartment 1.

[0034] like Figure 3 , Figure 4 As shown, in some embodiments, multiple load-bearing columns 21 are provided on the inner edge of the flow channel 8, and multiple isolation rods 22 are fixedly connected in the gap between the load-bearing columns 21. The isolation rods 22 are arranged vertically in the gap between the load-bearing columns 21, and the distance between two adjacent isolation rods 22 is 30mm. The load-bearing columns 21 can maintain the stability of the water retaining wall 4 and will not deform due to the large tonnage of the ship. By setting up the isolation rods 22, large fish or other organisms in the water can be prevented from entering the flow channel 8 and damaging the propeller 10 in the flow channel 8, thus preventing the propeller 10 from getting stuck.

[0035] like Figure 3 , Figure 4 As shown, in some embodiments, mounting seats 23 are symmetrically arranged inside the flow channel 8. The mounting seats 23 are rotatably penetrated by the rotating rod 9, and one end of the rotating rod 9 rotatably penetrates the side wall of the flow channel 8. The mounting seats 23 play a stable supporting role, which can make the rotating rod 9 and the propeller 10 rotate stably.

[0036] like Figure 1 , Figure 3 , Figure 4As shown, in some embodiments, the power assembly 11 includes a motor 1101, and a first pulley 1102, a second pulley 1103, and a transmission belt 1104 symmetrically arranged along the output end of the motor 1101. The motor 1101 is fixedly mounted on the side wall of the berthing hold 1. The first pulley 1102 is fixedly sleeved on the output end of the motor 1101. The second pulley 1103 is fixedly sleeved on the end of the rotating rod 9 located outside the guide groove 8. The transmission belt 1104 is sleeved on the same set of first pulley 1102 and second pulley 1103. The motor 1101 drives the first pulley 1102 to rotate, which in turn drives the second pulley 1103 to rotate via the transmission belt 1104. This causes the second pulley 1103 to drive the rotating rod 9 and the propeller 10 to rotate, thereby causing the water in the guide channel 8 and the berthing compartment 1 to flow from the outside to the inside. During the towing process, this can move the ship and reduce the tension on the towing vehicle 6. Compared with the traditional method of pulling the ship by only the towing rope, this reduces the possibility of the towing rope breaking and thus reduces the occurrence of safety accidents.

[0037] like Figure 1 , Figure 6 As shown, in some embodiments, the opening and closing assembly 13 includes a waterstop plate 1301, a support frame 1302, and an electric cylinder 1303 symmetrically arranged along the berthing hold 1. The waterstop plate 1301 is inserted into the water-retaining wall 4 and can block the through channel 12. The support frame 1302 is fixedly installed on the water-retaining wall 4. The electric cylinder 1303 is fixedly installed on the support frame 1302, and its end is fixedly connected to the top of the waterstop plate 1301. Before the ship is led to the berthing hold 1, the through channel 12 is opened by the opening and closing assembly 13, and the dock gate 2 is pulled away, so that water can quickly enter the berthing hold 1. When the ship is berthed, the dock gate 2 is closed, the through channel 12 is blocked by the opening and closing assembly 13, and then the water in the berthing hold 1 is pumped out by relevant equipment to prevent water from entering the berthing hold 1 during ship maintenance.

[0038] like Figure 1 , Figure 2 , Figure 7 As shown, in some embodiments, a drainage trough 24 is provided at the edge of the concrete base 3, and a high-pressure water pump 25 is fixedly installed on each of the two water retaining walls 4. The water inlet end of the high-pressure water pump 25 is fixedly connected to a water inlet pipe 26, and the bottom end of the water inlet pipe 26 is located in the drainage trough 24. The drain end of the high-pressure water pump 25 is fixedly connected to a drain pipe 27, and the drain pipe 27 is a flexible hose. When the ship enters the berth 1 and the berth 1 is closed, the water in the berth 1 can be quickly pumped out by the high-pressure water pump 25, so that the ship stops in the berth 1 as the water level in the berth 1 drops, which is convenient for the staff to carry out subsequent maintenance and repair of the ship.

[0039] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 6 , Figure 7 As shown, in some embodiments, a control console 28 is also fixedly installed on the retaining wall 4. The control console 28 is electrically connected to the winch 7, laser signal collector, motor 1101, electric cylinder 1303, and high-pressure water pump 25, respectively. It can be used to control the operation of various electrical devices and can be operated in both manual and automatic modes. By setting up a laser emitter 14 and a laser signal receiver 15, when the ship is fully inside the berth 1, the ship will block the laser emitted by the laser emitter 14, changing the signal received by the laser signal receiver 15, thereby causing the laser signal receiver 15 to feed back the signal to the control console 28. This allows the control console 28 to automatically control the operating status of various electrical devices. When the laser signal receiver 15 does not receive a laser signal, it will feed back a signal to the control console 28. The control console 28 controls the winch 7 to stop moving and controls the rotating rod 9 and propeller. 10 stops rotating, preventing the ship from moving, and controls the electric cylinder 1303 to drive the waterstop plate 1301 to sink, blocking the through channel 12. Then, the staff uses the dock gate 2 to close the berthing compartment 1 again, and controls the high-pressure water pump 25 through the control console 28 to pump out the water in the berthing compartment 1, so that the ship can be repaired and maintained. The whole process is more intelligent and reduces the labor intensity of the staff. In addition, it should be noted that the wiring diagram between the control console 28, winch 7, laser signal collector, motor 1101, electric cylinder 1303 and high-pressure water pump 25 in this invention is common knowledge in the field, and its working principle is already known technology. The models of winch 7, laser signal collector, motor 1101, electric cylinder 1303 and high-pressure water pump 25 are selected according to the actual use. Therefore, the control method and related wiring layout of the control console 28 will not be explained in detail.

Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments that can be applied to other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present invention without departing from the scope of the present invention shall still fall within the protection scope of the present invention.
