Description

Technical Field

[0001] This invention relates to shipbuilding, and more particularly to a mobile water suction device for a ship's curved pipe that is coated with a solidifying agent and contains a small amount of accumulated water. Background Technology

[0002] Shipbuilding requires a large number of pipes, each of which is bent into the required shape to meet the functional requirements of the ship's design. After the installation of ship pipes, especially bends, is completed, the inner walls of the pipes need to be cleaned to remove protective grease and other impurities. In practice, this is usually done using chemicals and seawater for rinsing and cleaning.

[0003] Currently, after the drug delivery cleaning of the pipeline is completed, seawater is added for rinsing, followed by a blowing method to dry and protect the pipeline. The drug delivery cleaning typically uses Drew, but some Drew will precipitate and solidify after cleaning. This solidified Drew often cannot be completely removed by seawater blowing, ultimately requiring disassembly for cleaning.

[0004] Because seawater flushing of the pipeline cannot completely remove water and solidified Dronium from corners and bends, water and Dronium residue often remain in the pipeline during subsequent use. This invention aims to adsorb the adhering solidified Dronium from corners and bends, achieving the purpose of cleaning and protecting the pipeline. Summary of the Invention

[0005] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a mobile water suction device for a ship's curved pipe that has solidified Drew chemical and a small amount of accumulated water. The device and method of this invention should be customizable to meet the cleaning and drying protection requirements of the pipe, reducing seawater chlorine corrosion and Drew chemical residue.

[0006] To achieve the above-mentioned objectives, the technical solution provided by this invention patent is as follows:

[0007] A mobile water suction device is provided for a ship's bend pipe that is coated with solidified Drew agent and has a small amount of water. The Drew agent and a small amount of water are adhered to the bend and dead corner of the ship's bend pipe. The mobile water suction device moves inside the ship's bend pipe and reaches the bend and dead corner to clean the adhered Drew agent and water. The mobile water suction device includes at least two roller modules, at least one hinge joint, and a control box. Two adjacent roller modules are connected together by a hinge joint. The control box is located at the hinge joint where the two roller modules are connected. The two adjacent roller modules form two bendable structures through the hinge joint.

[0008] The roller module comprises a central shaft and a disc. The central shaft passes vertically through the center of the disc. Two sets of functional components are symmetrically distributed on one side of the disc. Each set of functional components includes a first motor, a Mecanum wheel, a roller, a sponge track, and a second motor. A dry sponge roll is mounted on the first motor, and a water-absorbing sponge roll is mounted on the second motor. One end of the sponge track is wound on the dry sponge roll, and the other end is wound on the water-absorbing sponge roll. The middle part of the sponge track passes through the Mecanum wheel and the roller. A surrounding support plate surrounds the first motor, the dry sponge roll, and one Mecanum wheel; a surrounding support plate also surrounds the second motor, the water-absorbing sponge roll, and one Mecanum wheel.

[0009] The control box is connected to a storage power source, and the control box is equipped with control switches that are respectively connected to the first motor and the second motor. The control box is also wirelessly connected to a remote control switch.

[0010] The outer diameter of the disc is smaller than the inner diameter of the ship's curved pipe, the outer edge of the sponge track protrudes beyond the edge of the disc, and the outer edge of the Mecanum wheel's traveling wheel protrudes beyond the outer edge of the sponge track.

[0011] In the mobile water suction device for a ship's curved pipe with a small amount of accumulated water and a coagulating agent adhering to it, as an optimized structure, it includes two first roller modules, two second roller modules, three hinge joints, and a control box. There are two first roller modules, two second roller modules, and three hinge joints. The two first roller modules at both ends are connected to the two second roller modules on the inner side by a hinge joint, and the two second roller modules are connected together by hinge joints. The control box is located at the hinge joint where the two second roller modules are connected. The two first roller modules and the two second roller modules form a four-section bendable structure through the three hinge joints.

[0012] In the mobile water suction device for a ship's curved pipe with a solidifying agent and a small amount of accumulated water, the surrounding support plate is a pentagonal cylindrical structure, one end of which is vertically fixed on the disc, and the four surrounding support plates are symmetrically arranged around the central axis.

[0013] In the mobile water suction device of the ship's curved pipe with solidified Drew agent and a small amount of accumulated water, the middle part of the Mecanum wheel is used to accommodate the passage of the sponge track and provide rotational power, while the two sides are driving wheels that provide rotational and driving power.

[0014] In the mobile water suction device for a ship's curved pipe with a solidifying agent and a small amount of accumulated water, a trolley is provided at the bottom of the control box. The trolley is connected to the adjacent roller modules at the front and rear, and the start / stop switch of the trolley is wirelessly connected to the remote control switch.

[0015] In the mobile water suction device for a ship's curved pipe with a solidifying agent and a small amount of accumulated water, the two ends of the central shaft are provided with connectors, which are respectively connected to the hinge joints.

[0016] The present invention also provides a method for cleaning a ship's bend pipe that is coated with coagulant and contains a small amount of water. This method uses the aforementioned mobile water suction device and specifically includes the following steps:

[0017] The first step is to clean the ship's bend with Drew chemicals, then rinse it with seawater, and finally blow it with high-pressure air. During the cleaning, rinsing and blowing process, ensure that there is no grinding, painting or welding work around the bend.

[0018] The second step is to place the mobile water suction device in the ship's bend. At the initial position of the ship's bend, on a dry and clean part, first control the trolley to move forward to the bend.

[0019] The third step is to start the motor using the remote control switch. The Mecanum wheel on the first roller module rotates in one direction, and the Mecanum wheel on the second roller module rotates in the opposite direction. By controlling the motor speeds of the first roller module and the second roller module to be the same, the moving water suction device starts to rotate at the same speed and move in one direction to reach the area of ​​the pipe that is wet and where the Drew agent is adhered for operation.

[0020] The fourth step involves the mobile water-absorbing device moving using Mecanum wheels and using sponge tracks for friction cleaning. If there is water accumulation, the sponge tracks will absorb it, and the water-absorbing sponge roll will absorb the water inside the sponge tracks.

[0021] Fifth step: After the mobile water absorption device finishes working for a single time, come out of the pipe and check the water absorption and the cleanliness of the sponge surface to determine if there is still water accumulation and cleanliness inside. Then replace the sponge and start the water absorption work again or stop the device from working.

[0022] The sixth step is to retrieve the mobile water suction device for later use after cleaning, disassemble and check the dead corners of the pipes to ensure that the work is done properly, and then reposition the ship's pipes and bends.

[0023] Based on the above technical solution, the mobile water suction device and cleaning method for a ship's curved pipe with coagulant and a small amount of accumulated water has achieved the following technical effects through practical application:

[0024] 1. The mobile water-absorbing device of the present invention utilizes the principles of sponge water absorption, track rotation, and Mecanum wheel travel to achieve water absorption and unidirectional rotation and travel within the pipe. Simultaneously, the sponges of two roller modules contain Drew cleaning agent, which performs unidirectional rotation and cleaning when the device travels to the corresponding position.

[0025] 2. The mobile water suction device and cleaning method of the present invention can also be customized in size to meet the purpose of cleaning and drying the pipeline, reducing the corrosion of the pipeline by seawater chlorine and the residue of Drew chemical.

[0026] 3. The mobile water suction device and cleaning method of the present invention adopts a segmented connection method, connecting at least two roller modules through a hinge joint, which can achieve the purpose of automatic bending and movement. It is targeted at cleaning the bending parts and dead corners of the pipeline on the ship, achieving specific cleaning purposes that other cleaning tools cannot achieve. Attached Figure Description

[0033] The following detailed description, in conjunction with the accompanying drawings and specific embodiments, provides a mobile water suction device and cleaning method for a ship's curved pipe coated with coagulant and containing a small amount of accumulated water, in order to provide a clearer understanding of its structural composition and workflow. However, this should not be construed as limiting the scope of protection of the present invention. Example 1

[0034] This embodiment provides a mobile water suction device for a ship's bend pipe that is adhered to with solidified Drew agent and a small amount of water. Drew agent and a small amount of water are adhered to the bend position and dead corner of the ship's bend pipe. The mobile water suction device travels inside the ship's bend pipe and reaches the bend position and dead corner to clean the adhered Drew agent and water.

[0035] like Figure 1-2 As shown, the mobile water-absorbing device includes a first roller module, a second roller module, a hinge joint 2, and a control box 3. There are two first roller modules, two second roller modules, and three hinge joints 2. The two first roller modules at both ends are connected to the two second roller modules on the inner side by a hinge joint 2. The two second roller modules are connected together by the hinge joints 2. The orientation of the two first roller modules is opposite to the placement orientation of the two second roller modules. The control box 3 is located at the hinge joint 2 where the two second roller modules are connected. The two first roller modules and the two second roller modules form a four-section bendable structure through the three hinge joints 2.

[0036] like Figure 3 and Figure 4 As shown, the first roller module and the second roller module have the same structure, both being roller module 1. The roller module 1 consists of a central shaft 12 and a disk 11. The central shaft 12 passes vertically through the middle of the disk 11. Two sets of functional components are symmetrically distributed on one side of the disk 11. Each set of functional components includes a first motor 13, a Mecanum wheel 17, a roller 19, a sponge track 18, and a second motor 16. A drying sponge roll 14 is provided on the first motor 13, and a water-absorbing sponge roll 15 is provided on the second motor 16. One end of the sponge track 18 is wound around the drying sponge. One end of the sponge is wound around the absorbent sponge roll 15, and the middle part of the sponge track 18 passes through the Mecanum wheel 17 and multiple rollers 19. A peripheral support plate 10 surrounds the first motor 13, the dry sponge roll 14, and the Mecanum wheel 17; a peripheral support plate 10 also surrounds the second motor 16, the absorbent sponge roll 15, and the Mecanum wheel 17. Thus, four pentagonal peripheral support frames 10 are symmetrically arranged in a roller module 1, with one corner of the pentagon facing the central axis 12, and are symmetrically distributed. The edges of the pentagons do not exceed the edge of the disc 11. The peripheral support frames 10 surrounded by pentagons are open at the location of the Mecanum wheel 17, with half of the Mecanum wheel 17 inside and half outside, so that the sponge track 18 can pass through the rollers 19 and wrap around the absorbent sponge roll 15 or the dry sponge roll 14.

[0037] like Figure 1 As shown, the control box 3 is connected to a storage power source. Inside the control box 3 are control switches that connect to the first motor 13 and the second motor 16, respectively. The control box 3 is also wirelessly connected to a remote control switch. The storage power source connects to the control box 3 and, through the control box 3, connects to the first motor 13 and the second motor 16, controlling their start and stop. Furthermore, a trolley 4 is located at the bottom of the control box 3. This trolley 4 is connected to the adjacent second roller module at the front and rear, respectively. The start / stop switch of the trolley 4 is wirelessly connected to the remote control switch. The remote control switch controls the trolley's movement, thus dragging the mobile water suction device forward or backward, achieving the purpose of moving the entire mobile water suction device to the work area without affecting its normal operation. After the mobile water suction device has finished its work, the trolley can be withdrawn using the remote control.

[0038] For ease of operation, the outer diameter of the disc 11 is smaller than the inner diameter of the ship's curved pipe. The outer edge of the sponge track 18 protrudes beyond the edge of the disc 11, and the outer edge of the traveling wheel of the Mecanum wheel 17 protrudes beyond the outer edge of the sponge track 18. The outer diameter of the mobile suction device is generally smaller than the inner diameter of the ship's curved pipe to be cleaned, allowing it to move freely inside or backward. However, it cannot be too small, otherwise it will not be effective in cleaning. Ideally, the diameter should be slightly smaller, but the sponge track 18 should still be able to contact the inner wall to achieve cleaning.

[0039] For safety reasons, in order to protect the motor, the water-absorbing sponge column and the dry sponge column, the peripheral support plate 10 is designed as a pentagonal cylindrical structure, but one side of it is an open edge through which the sponge track 10 passes. One end of the peripheral support plate 10 is vertically fixed on the disc 11, and the four peripheral support plates 10 are symmetrically arranged around the central axis 12.

[0040] like Figure 2 As shown, during the cleaning process, the Mecanum wheel 17 accommodates the sponge track 18 as it passes through, and the sponge track 18 provides rotational and propulsive power to the two side travel wheels. A motor drives the water-absorbing sponge columns and dry sponge columns at both ends of the sponge track 18 to rotate, thereby rotating the Mecanum wheel 17, thus forming two power sources for the mobile water-absorbing device: rotation and propulsion.

[0041] To achieve connectivity and flexibility, allowing it to bend and move forward within curved pipes, the central shaft 12 has connectors at both ends, which are respectively connected to the hinge joints 2. Furthermore, through the design of the connectors, the mobile water suction device can include at least two roller modules 1, or it can be expanded to include multiple modules, depending on the cleaning status and needs. Example 2

[0042] This embodiment provides a method for cleaning a ship's bend pipe that is coated with coagulant and contains a small amount of water. The method utilizes the aforementioned mobile suction device and specifically includes the following steps:

[0043] The first step involves cleaning the ship's bends with Drew chemicals, followed by rinsing with seawater, and then blowing them with high-pressure air. During the cleaning, rinsing, and blowing processes, it is ensured that there is no grinding, painting, or welding work around the bends, mainly to avoid causing more pollution and affecting the cleaning effect.

[0044] The second step is to place the mobile water suction device in the bend of the ship. The initial position of the bend is a dry and clean area. First, use the remote control switch to control the trolley to move forward until the whole thing moves close to the bend and the corner.

[0045] The third step, as Figure 5 As shown, the first or second motor is started using a remote control switch. The Mecanum wheel on the first roller module rotates in one direction, and the Mecanum wheel on the second roller module rotates in the opposite direction. By controlling the first or second motor on the first and second roller modules to rotate at the same speed, the moving water suction device starts to rotate and move in one direction at the same speed to reach the wet and adhering parts of the pipe for cleaning and water suction. In order to achieve the cleaning of solidified Drew agent, it is necessary to add a special cleaning agent to the sponge track when necessary.

[0046] The fourth step involves the mobile suction device, propelled by Mecanum wheels, using sponge tracks for friction cleaning. If water accumulates, the sponge tracks absorb it, and the absorbent sponge rolls further clean the water within. Ideally, the outer diameter of the entire mobile suction device is slightly smaller than the inner diameter of the bend in the hull, allowing the sponge tracks to make full contact with the inner wall of the bend and providing elasticity. In this case, even if a significant amount of solidified Drew chemicals adheres to the bend, it can be cleaned using the rotating sponge tracks. In practice, during seawater flushing, residual Drew chemicals and accumulated seawater are usually located at the bottom of the bend; the mobile suction device can easily absorb and clean them by passing through.

[0047] Step 5, as Figure 6 As shown, in situations where there is a large amount of desiccant or a lot of water, the device needs to reciprocate to perform the cleaning operation. Therefore, it is necessary to control the backward movement and perform multiple reciprocating operations to achieve the purpose of thorough cleaning. After a single operation, the mobile water suction device still needs to be pulled out of the pipe to check the water absorption and the cleanliness of the sponge surface, to determine whether there is still water accumulation and the cleanliness status inside, and then replace the sponge to perform water absorption again or stop the device operation.

[0048] The sixth step is to retrieve the mobile water suction device for later use after cleaning, disassemble and check the dead corners of the pipes to ensure that the work is done properly, and then reposition the ship's pipes and bends.

[0049] This invention is applicable to the cleaning of adhering and solidified Drew chemicals on the inner wall of bends and to the absorption of small amounts of moisture. It can be customized in size to meet the purpose of cleaning and drying pipelines, reducing seawater chlorine corrosion and Drew chemical residue.
