[0054] Reference Figure 1-4 , an embodiment of the present application provides a cleaning device for a weld in a pipeline, comprising:

[0055] Support shaft 1;

[0056] The throwing mechanism 2 is sleeved on the supporting shaft 1; the throwing mechanism 2 is provided with a plurality of first through holes 21 along the radial direction of the supporting shaft 1;

[0057] The first power mechanism 3 is used to drive the throwing mechanism 2 to rotate around the support shaft 1;

[0058] A driving mechanism 4, used for driving the first power mechanism 3;

[0059] A feeding mechanism 5, used for feeding materials to the throwing mechanism 2;

[0060] The second power mechanism 6 is used to drive the throwing mechanism 2, the first power mechanism 3, and the feeding mechanism 5 to move along the axial direction of the support shaft 1;

[0061] A first supporting mechanism 7, arranged at a first end of the supporting shaft 1;

[0062] The second supporting mechanism 8 is arranged at the second end of the supporting shaft 1 .

[0063] Specifically, the support shaft 1 is the core structure of the cleaning device, and all other components move and operate around the support shaft 1 .

[0064] The throwing mechanism 2 is used to throw out cleaning materials to clean the weld of the inner wall of the pipeline. The cleaning materials are thrown out from the first through holes 21. It can be understood that the first through holes 21 can be evenly arranged on the side of the throwing mechanism 2. The number of the first through holes 21 can be set according to actual needs. For example, the number of the first through holes 21 is 6 or 8. It can also be understood that the cleaning material is a material that can clean the weld without damaging the weld, such as steel sand. It can also be understood that a light, high-strength, wear-resistant material can be selected as the material of the throwing mechanism 2.

[0065] Driven by the first power mechanism 3 and the second power mechanism 6, the throwing mechanism 2 rotates at a high speed around the support shaft 1 (i.e., rotates at a high speed radially along the support shaft 1) and moves axially along the support shaft 1. During the movement, cleaning materials are thrown out from the first through hole 21, thereby achieving a cleaning effect on the weld.

[0066] The first supporting mechanism 7 and the second supporting mechanism 8 are used to fix and support the cleaning device in the area to be cleaned in the pipeline when in use, and the cleaning device can be moved in the pipeline when not in use.

[0067] It can be understood that the first supporting mechanism 7 and the second supporting mechanism 8 can use a telescopic structure. When in use, the telescopic structure is extended to fix and support the cleaning device on the inner wall of the pipeline. When not in use, the telescopic structure is shortened to allow the cleaning device to move in the pipeline.

[0068] It is also understandable that the first supporting mechanism 7 and the second supporting mechanism 8 can also use an inflatable mechanism. When in use, the first inflatable mechanism and the second inflatable mechanism are inflated, and the inflated first inflatable mechanism and the second inflatable mechanism can be supported on the inner wall of the pipeline to fix and support the entire cleaning device in the area to be cleaned in the pipeline. After use, the gas in the first inflatable mechanism and the second inflatable mechanism is released, and the position of the cleaning device can be moved in the pipeline to the next area to be cleaned or moved out of the pipeline.

[0069] It is also understandable that the first supporting mechanism 7 may use an inflatable mechanism and the second supporting mechanism 8 may use a telescopic structure, or the first supporting mechanism 7 may use a telescopic structure and the second supporting mechanism 8 may use an inflatable mechanism, and there is no limitation to this.

[0070] In this embodiment, the first power mechanism 3 and the second power mechanism 6 cooperate to drive the throwing mechanism 2 to move radially and axially along the support shaft 1, which can ensure the comprehensive cleaning of a section of the weld in the inner wall of the pipeline, with high cleaning efficiency and good cleaning effect.

[0071] In one embodiment, the first power mechanism 3 includes:

[0072] The sliding shaft 31 is sleeved on the supporting shaft 1.

[0073] A rotating shaft 32, the rotating shaft 32 is sleeved on the sliding shaft 31, and the rotating shaft 32 is connected to the throwing mechanism 2;

[0074] A rotor 33, wherein the rotor 33 is sleeved on the rotating shaft 32;

[0075] A stator 34, the stator 34 is sleeved on the rotor 33;

[0076] The housing 35 , the rotating shaft 32 , the rotor 33 , and the stator 34 are arranged inside the housing 35 .

[0077] Specifically, the sliding shaft 31 is sleeved on the supporting shaft 1 , and the first power mechanism 3 can move on the supporting shaft 1 along the axial direction of the supporting shaft 1 through the driving of the second power mechanism 6 .

[0078] The rotor 33 is a rotating component in the first power mechanism 3 , and is mainly responsible for converting the input power into mechanical motion, and generating a rotational force through interaction with the stator 34 .

[0079] The rotating shaft 32 is sleeved on the sliding shaft 31 and is a power transmission channel. When the first power mechanism 3 is started, the driving mechanism 4 drives the rotor 33 to rotate, and the rotating shaft 32 transmits the rotational motion of the rotor 33 to the throwing mechanism 2, so that the throwing mechanism 2 makes a circular motion around the supporting shaft 1, thereby throwing the cleaning material out of the throwing mechanism 2 at high speed.

[0080] The rotating shaft 32, the rotor 33 and the stator 34 are arranged inside the housing 35 to provide protection.

[0081] In this embodiment, the first power mechanism 3 can drive the throwing mechanism 2 to make a circular motion around the support shaft 1 through the cooperation of the rotating shaft 32, the rotor 33, and the stator 34, so as to ensure that the cleaning material is thrown out at a high speed to achieve the purpose of cleaning the weld. The sliding shaft 31 can make the first power mechanism 3 and the throwing mechanism 2 move radially along the support shaft 1 to achieve the purpose of cleaning a section of the weld in the pipeline.

[0082] In one embodiment, a first air inlet is provided on the housing 35 , and positive pressure gas is input into the first power mechanism 3 through the first air inlet.

[0083] Specifically, the first air inlet is connected to the positive pressure gas delivery device through a gas pipeline, and it is understandable that a one-way valve can be provided on the gas pipeline. When positive pressure gas needs to be input into the first power mechanism 3, the one-way valve is opened, and the positive pressure gas delivery device inputs positive pressure gas into the first power mechanism 3 through the first air inlet.

[0084] In this embodiment, positive pressure gas is input into the first power mechanism 3 so that the first power mechanism 3 can have a dustproof effect.

[0085] In one embodiment, the first power mechanism 3 is externally covered with a first dust cover 9 .

[0086] Specifically, the first dust cover 9 can use a retractable dust cover, wherein one end of the first dust cover 9 can be fixed on the first inflation mechanism.

[0087] In this embodiment, the first dust cover 9 can protect the first power mechanism 3 from dust, or prevent the cleaning materials thrown out by the throwing mechanism 2 from hitting and damaging the first power mechanism 3.

[0088] In one embodiment, the first supporting mechanism 7 uses a first inflation mechanism; and the second supporting mechanism 8 uses a second inflation mechanism.

[0089] In one embodiment, the first inflation mechanism comprises:

[0090] The first annular support frame 71 is sleeved on the support shaft 1;

[0091] A first inflatable ring 72 is sleeved on the outside of the first annular support frame 71;

[0092] A first inflation hole is provided on the first annular support frame 71 and is connected to the first inflation ring 72;

[0093] The second inflation mechanism comprises:

[0094] The second annular support frame 81 is sleeved on the support shaft 1;

[0095] The second inflatable ring 82 is sleeved on the outside of the second annular support frame 81;

[0096] The second inflation hole is formed on the second annular support frame 81 and is communicated with the second inflation ring 82 .

[0097] Specifically, the sizes of the first annular support frame 71 and the second annular support frame 81 can be set in various specifications, and the appropriate size can be selected according to the requirements of different pipe inner diameters. The sizes of the first inflatable ring 72 and the second inflatable ring 82 match those of the first annular support frame 71 and the second annular support frame 81.

[0098] The first inflation hole and the second inflation hole of the first inflation mechanism and the second inflation hole of the second inflation mechanism are respectively connected to the positive pressure gas delivery device through the gas pipeline. It is understandable that a one-way valve can be set on each gas pipeline. It is also understandable that the two inflation mechanisms can share the same positive pressure gas delivery device or not. It is also understandable that the two inflation mechanisms can also share the same positive pressure gas delivery device with the first power mechanism 3 or not.

[0099] When the cleaning device needs to clean a section of the weld in the pipeline, the first inflatable mechanism and the second inflatable mechanism need to be placed at the position of the weld to be cleaned, and then their respective one-way valves are opened, and the positive pressure gas delivery equipment inflates air into their respective inflatable circles through their respective inflation holes until the first inflatable mechanism and the second inflatable mechanism fix and support the cleaning device at the position of the weld to be cleaned, and then close their respective one-way valves.

[0100] In this embodiment, through the cooperation of the annular support frame and the inflatable ring, the position of the cleaning device can be flexibly moved so that the cleaning process can be cyclical. That is, after cleaning a cleaning area, the gas in the inflatable ring is released, and the cleaning device can be moved to the next area to be cleaned in the pipeline, and then the inflatable ring is inflated to fix the cleaning device.

[0101] It can be understood that in order to save space in the cleaning device, the driving mechanism 4 can be installed on the inner ring of the first annular support frame 71.

[0102] In one embodiment, a first baffle 73 is disposed inside the first annular support frame 71 ; a second baffle 83 is disposed inside the second annular support frame 81 ;

[0103] At least one of the first baffle plate 73 and the second baffle plate 83 is provided with an air pressure balance hole 731 , and an air permeable net is installed on the air pressure balance hole 731 .

[0104] Specifically, the air pressure balance hole 731 can be set on any baffle plate, or can be set on both baffle plates. Figure 1 and Figure 3 In the figure, it is shown as an example that it is set on the first baffle 73.

[0105] By designing the air pressure balance hole 731, the excess positive pressure gas inputted into the first power mechanism 3 can be discharged. By setting the air permeable net, the cleaning materials thrown out by the throwing mechanism 2 will not reach the area outside the cleaning area, and at the same time, it has a ventilation effect. It can be understood that the air permeable net can be a combination of a filter net and air permeable cotton.

[0106] In one embodiment, a third through hole and a fourth through hole are formed on the second baffle 83;

[0107] The second power mechanism 6 comprises:

[0108] The motor 61 is mounted on the second baffle 83;

[0109] A screw rod 62, wherein a first end of the screw rod 62 is connected to a second end surface of the fixed material dividing member 53, and a second end of the screw rod 62 passes through a third through hole and is connected to the motor 61;

[0110] The guide rod 63 has a first end connected to the second end surface of the fixed material dividing member 53 and a second end passing through the fourth through hole.

[0111] In this embodiment, the cleaning material in the feed pipe 51 is transported to the throwing mechanism 2 by the cooperation of the rotating material dividing member 52 and the fixed material dividing member 53 .

[0112] In a real example, the second baffle 83 is provided with a third through hole and a fourth through hole;

[0113] The second power mechanism 6 comprises:

[0114] The motor 61 is mounted on the second baffle 83;

[0115] A screw rod 62, wherein a first end of the screw rod 62 is connected to a second end surface of the fixed material dividing member 53, and a second end of the screw rod 62 passes through a third through hole and is connected to the motor 61;

[0116] The guide rod 63 has a first end connected to the second end surface of the fixed material dividing member 53 and a second end passing through the fourth through hole.

[0117] Specifically, the motor 61 is a power source, responsible for converting electrical energy into mechanical energy, generating power through rotation, and driving the movement of the screw 62. The screw 62 converts the rotational motion of the motor 61 into linear motion, so that the feeding mechanism 5, the throwing mechanism 2, the first power mechanism 3, the screw 62, and the guide rod 63 move along the axial direction of the support shaft 1.

[0118] The guide rod 63 provides a stable linear guide to ensure that the movement of the screw rod 62 is linear, avoiding deviation and wear caused by lateral forces.

[0119] In this embodiment, the power transmission efficiency is high through the combination of the motor 61 and the screw rod 62; the thread of the screw rod 62 ensures precise displacement control, and the guide rod 63 can effectively reduce the error, and the guide rod 63 can also provide support to reduce the vibration and swing of the cleaning device during movement.

[0120] In one embodiment, the feeding mechanism 5 , the screw rod 62 , and the guide rod 63 are covered with a second dust cover 10 .

[0121] Specifically, the second dust cover 10 may be a retractable dust cover, wherein one end of the second dust cover 10 may be fixed on the second inflation mechanism.

[0122] In this embodiment, the second dust cover 10 can protect the feeding mechanism 5 and the screw rod 62 and the guide rod 63 from dust, or prevent the cleaning materials thrown out by the throwing mechanism 2 from hitting and damaging the feeding mechanism 5 and the screw rod 62 and the guide rod 63.

[0123] The above are only specific implementations of the present application, but the protection scope of the present application is not limited thereto. Any changes or substitutions within the technical scope disclosed in the present application should be included in the protection scope of the present application. Therefore, the protection scope of the present application should be based on the protection scope of the claims.
