After the installation of ship pipes, especially bent pipes, the inner wall of the pipe needs to be cleaned to remove grease and other impurities. In practical operation, chemicals and seawater are usually used for flushing and cleaning.

[0003] At present, after the drug-feeding cleaning of the pipeline is completed, seawater is added for cleaning, and then the pipeline is dried and protected by blowing.

[0033] Below we will further describe in detail the mobile water suction device and cleaning method of the ship's curved pipe with solidified Drew agent and a small amount of accumulated water in combination with the accompanying drawings and specific embodiments, so as to more clearly understand its structural composition and working process, but this cannot be used to limit the scope of protection of the present invention.

[0034] Example 1

[0035] This embodiment provides a mobile water suction device for a ship's curved pipe with solidified Drew agent and a small amount of accumulated water adhered thereto. Drew agent and a small amount of accumulated water adhere to the curved position and dead corner of the ship's curved pipe. The mobile water suction device travels in the ship's curved pipe and reaches the curved position and dead corner to clean the adhered Drew agent and accumulated water.

[0036] like Figure 1-2 As shown, the mobile water absorption device includes two first roller modules, two second roller modules, three articulated joints 2 and a control box 3, the first roller modules are provided with two, the second roller modules are provided with two, and the articulated joints 2 are provided with three. The two first roller modules located at both ends are respectively connected to the two second roller modules located on the inner side by an articulated joint 2, and the two second roller modules are connected together by an articulated joint 2. The control box 3 is arranged at the articulated joint 2 where the two second roller modules are connected, and the two first roller modules and the two second roller modules form a four-section bendable structure through the three articulated joints 2.

[0037] like Figure 3 and Figure 4 As shown, the structure of the roller module 1 includes a central axis 12 and a disc 11, wherein the central axis 12 vertically passes through the middle of the disc 11, and two groups of functional components symmetrically distributed are fixed on one side of the disc 11, each group of functional components includes a first motor 13, a Mecanum wheel 17, a roller 19, a sponge track 18, and a second motor 16, wherein a dry sponge roll column 14 is provided on the first motor 13, and a water-absorbing sponge roll column 15 is provided on the second motor 16, and one end of the sponge track 18 is rolled on the dry sponge roll column 14, and the other end is rolled on the On the water-absorbing sponge roll column 15, the middle of the sponge track 18 passes through the Mecanum wheel 17 and multiple rollers 19 respectively. The first motor 13, the dry sponge roll column 14 and a Mecanum wheel 17 are surrounded by a surrounding support plate 10; the second motor 16, the water-absorbing sponge roll column 15 and a Mecanum wheel 17 are also surrounded by a surrounding support plate 10. In this way, four pentagonal surrounding support frames 10 are symmetrically arranged in one roller module 1, and one corner of the pentagon faces the central axis 12, and they are symmetrically distributed, and the edges of the pentagons do not exceed the edges of the disc 11. The surrounding support frame 10 surrounded by the pentagon is open at the location of the Mecanum wheel 17, and the Mecanum wheel 17 is half inside and half outside, so that the sponge track 18 can pass through and wrap around the water-absorbing sponge column 15 or the dry sponge column 14.

[0038] like Figure 1As shown, the control box 3 is connected to a storage power supply, and a control switch connected to the first motor 13 and the second motor 16 is provided in the control box 3, and the control box 3 is wirelessly connected to a remote control switch. The storage power supply is connected to the control box 3, and is connected to the first motor 13 and the second motor 16 through the control box 3 to control the start and stop of the first motor 13 and the second motor 16. In addition, a trolley 4 is provided at the bottom of the control box 3, and the trolley 4 is respectively connected to the adjacent roller modules 4 front and back, and the start and stop switch of the trolley 4 is wirelessly connected to the remote control switch. The trolley is controlled to move forward or backward by the remote control switch, and then the mobile water absorption device is dragged forward or backward, so as to achieve the purpose of moving the mobile water absorption device as a whole to the working position, and it does not affect the normal operation of the mobile water absorption device. When the mobile water absorption device is finished, the trolley can be withdrawn by the remote control.

[0039] In order to facilitate the construction work, 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 from the edge of the disc 11, and the outer edge of the traveling wheel of the Mecanum wheel 17 protrudes from the outer edge of the sponge track 18. The outer diameter of the mobile water suction device is smaller than the inner diameter of the ship's curved pipe to be cleaned, so that it can move freely inside or back, but it cannot be too small, otherwise it will not play a cleaning role. It is best to have a slightly smaller diameter but the sponge track 18 can contact the inner wall to achieve cleaning.

[0040] For safety reasons, in order to protect the motor and the water-absorbing sponge column and the drying sponge column, the peripheral support plate 10 is designed as a pentagonal cylindrical structure, but one side of which is an open edge for the sponge track 10 to pass through, and 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.

[0041] like Figure 2 As shown, during the cleaning process, the middle of the Mecanum wheel 17 accommodates the sponge track 18 and provides the rotation power of the traveling wheel, and the two sides provide the rotation and travel power for the traveling wheel. The motor drives the water absorption sponge column and the drying sponge column at both ends of the sponge track 18 to rotate, thereby realizing the rotation of the Mecanum wheel 17, thereby forming two powers for the rotation and travel of the mobile water absorption device.

[0042] In order to achieve connection and bendability, and be able to bend and move forward in the curved pipe, the two ends of the central axis 12 are provided with connecting pieces, which are respectively connected to the articulated joints 2. And through the design of the connecting pieces, the mobile water suction device can include at least two roller modules 1, and can also be expanded into multiple ones, and expanded applications can be performed according to the cleaning state and needs.

[0043] Example 2

[0044] This embodiment provides a method for cleaning a ship elbow with solidified Drew agent and a small amount of accumulated water, the method using the above-mentioned mobile water suction device, the method specifically comprising the following steps:

[0045] In the first step, the ship's bent pipes are cleaned with Drew chemicals and then rinsed with seawater. After rinsing, they are blown with high-pressure air. During the cleaning, flushing and blowing process, ensure that there is no grinding, painting and welding work around the bent pipes, mainly to avoid causing more pollution and affecting the cleaning effect.

[0046] The second step is to place the mobile water suction device in the ship's curved pipe, dry and clean the area at the initial position of the ship's curved pipe, and first use the remote control switch to control the trolley to move forward until the entire device moves to a position close to the curved area and the blind spot.

[0047] The third step is Figure 5 As shown, the motor is started by 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 motor speeds of the first roller module and the second roller module to be the same, the mobile water absorption device starts to rotate and move in one direction at the same speed to move to the wet and adhered Drew agent parts of the pipeline for cleaning and water absorption operations. In order to clean the solidified Drew agent, a special cleaning agent needs to be added to the sponge track when necessary to clean the Drew agent.

[0048] The fourth step is that the mobile water absorption device is driven by the Mecanum wheel and uses the sponge track for friction cleaning. If there is water accumulation, the sponge track will absorb it, and the water in the sponge track will be absorbed by the water absorption sponge roll column; ideally, the outer diameter of the entire mobile water absorption device is slightly smaller than the inner diameter of the curved pipe on the hull, so that the sponge track can fully contact the inner wall of the curved pipe and have elastic expansion and contraction. In this case, even if there is a lot of solidified Drew agent adhered to the curved position of the curved pipe, it can be cleaned by the rotating sponge track. In practice, when the seawater is flushed, the residual Drew agent and the accumulated seawater are usually at the bottom of the curved pipe, and they can be absorbed and cleaned as long as the mobile absorption device passes.

[0049] Step 5: Figure 6 As shown, when there are more dry Drew agents or more accumulated water, the device needs to reciprocate to achieve the cleaning operation, so it is necessary to control the retreat and achieve the purpose of complete cleaning through multiple reciprocating operations. After the mobile water absorption device is completed at a single time, it is still necessary to start and withdraw from the pipeline to check the water absorption situation and the cleanliness of the sponge surface, and determine whether there is still accumulated water and the cleanliness status, and then replace the sponge and perform water absorption again or end the device work.

[0050] Step 6. After the cleaning is completed, the mobile water suction device will be recovered for standby use, and the blind corners of the pipeline will be disassembled to check whether the work is in place, and the ship's pipelines and elbows will be reset.

[0051] This invention is suitable for cleaning the solidified Drew agent adhered to the inner wall of the bent pipe and absorbing a small amount of water. It can be customized in size to meet the purpose of cleaning and drying the pipeline, reducing seawater chlorine corrosion and Drew agent residue.
