Description

Technical Field

[0001] This utility model belongs to the field of pipeline processing technology, and more specifically, it relates to a bimetallic composite pipe inner wall cleaning and testing device. Background Technology

[0002] Bimetallic composite pipes, as a type of high-efficiency special pipe material, consist of inner and outer layers made of different metal materials tightly bonded together through metallurgical, mechanical, or explosive bonding processes. They combine the excellent corrosion resistance of the inner layer with the superior mechanical strength of the outer layer, making them widely used in harsh environments such as petroleum, chemical, and marine engineering. However, during long-term service, their inner walls are prone to scaling, corrosion product deposition, or residual processing impurities. These defects not only directly affect pipeline transport efficiency but may also lead to safety hazards such as accelerated localized corrosion and composite interface failure. Therefore, to ensure the long-term safe operation and stable performance of composite pipes, regular cleaning and inspection of the inner walls of bimetallic composite pipes has become a crucial aspect of their life-cycle management.

[0003] Manual pipe cleaning is inefficient and makes it difficult to check the cleaning status of the pipe's inner wall, which is not conducive to accurate detection of the pipe's inner wall condition later.

[0004] Therefore, in view of this, we have studied and improved the existing structure and its shortcomings, and provided a bimetallic composite pipe inner wall cleaning and detection device in order to achieve a more practical purpose. Utility Model Content

[0005] To address the aforementioned technical problems, this utility model provides a bimetallic composite pipe inner wall cleaning and inspection device, which solves the problems of low efficiency in manual pipe cleaning, inconvenience in inspecting the cleaning status of the inner wall of the pipe, and difficulty in accurately detecting the condition of the inner wall of the pipe later.

[0006] The purpose and effectiveness of this utility model's bimetallic composite pipe inner wall cleaning and testing device are achieved through the following specific technical means:

[0007] A bimetallic composite pipe inner wall cleaning and inspection device includes a cleaning chamber. A central shaft is installed inside the cleaning chamber via a first motor. A composite pipe mounting bracket is sleeved on the central shaft. Cylinders are installed on both sides of the cleaning chamber. The output end of each cylinder passes through the cleaning chamber and connects to a cleaning component. The cleaning component includes a hollow frame on which a pipe endoscope is installed. An L-shaped ring is rotatably installed at one end of the hollow frame, and the other end is connected to a cylinder. A water spray component passes through the hollow frame, and brushes are distributed around the L-shaped ring.

[0008] Furthermore, racks are distributed on the outer periphery of the L-shaped ring extending inside the hollow frame, and a side chamber protrudes from one side of the hollow frame. A gear is rotatably installed inside the side chamber, and the gear is driven by a second motor inside the hollow frame. The gear meshes with the rack.

[0009] Furthermore, a bearing is provided between the water spray component and the L-shaped ring.

[0010] Furthermore, the water spray component includes a water collection sleeve passing through the center of the hollow frame. The end of the water collection sleeve extends out of the hollow frame and is provided with multiple nozzles, which are distributed laterally around the circumference. One end of the water collection sleeve is connected to an external water source and a water pump through a water pipe.

[0011] Furthermore, the mounting bracket includes a rotating sleeve fitted on the central shaft, with multiple rotating frames distributed circumferentially at both ends of the rotating sleeve. The rotating frames are C-shaped, and connecting rings are installed on the rotating frames to form a circular space for accommodating the pipe.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] Multiple composite pipes to be cleaned are placed in the composite pipe mounting rack inside the cleaning box. The rotation of the central shaft moves the composite pipes to a position between the two cleaning components. The cylinder pushes the water spray component and the brush to clean the inner wall of the pipe. At the same time, the endoscope can observe the cleaning status of the inner wall of the pipe, improving cleaning efficiency and saving labor costs. Attached Figure Description

[0024] Example:

[0025] As attached Figure 1 To be continued Figure 5 As shown:

[0026] This utility model provides a cleaning and inspection device for the inner wall of a bimetallic composite pipe, including a cleaning tank 1 with an opening at the top front for placing or removing the metal composite pipe. A central shaft 2 is installed inside the cleaning tank 1, driven by a first motor 5. A composite pipe mounting bracket is fitted onto the central shaft 2. Figure 1 and Figure 5 As shown, the mounting frame includes a rotating sleeve 3 fitted on the central shaft 2. Multiple rotating frames 4 are distributed circumferentially at both ends of the rotating sleeve 3. The rotating frames 4 are C-shaped, and connecting rings 9 are installed on the rotating frames 4 to form a circular space for accommodating the pipe. The connecting rings 9 are connected to the rotating frames 4 by bolts. Due to the self-locking of the first motor 5, the central shaft 2 is stationary. After the composite pipe is placed in the rotating frame 4 and the connecting rings 9 are installed, the first motor 5 drives the central shaft 2 to rotate, so that another set of rotating frames 4 corresponds to the opening of the cleaning tank 1.

[0027] Cylinders 6 are installed on both sides of the cleaning chamber 1. The output end of each cylinder 6 passes into the cleaning chamber 1 and connects to the cleaning component 7. The cleaning component 7 includes a hollow frame 701 on which a tubular endoscope is installed. An L-shaped ring 703 is rotatably installed at one end of the hollow frame 701. Figure 2 and Figure 4 As shown, the other end is connected to a cylinder 6, which can drive the hollow frame 701 to move inside the pipe. A water spraying component 8 is installed inside the hollow frame 701, including a water collecting sleeve 801 installed in the center of the hollow frame 701. The end of the water collecting sleeve 801 extends out of the hollow frame 701 and is provided with multiple nozzles, which are distributed horizontally in a circular pattern. One end of the water collecting sleeve 801 is connected to an external water source and a water pump (not shown in the figure) through a water pipe 802. During the movement of the hollow frame 701, the nozzles drive the pipe to flush the inner wall of the pipe.

[0028] Furthermore, the L-shaped ring 703 is equipped with brushes 705 distributed around its periphery, which can clean the dirt on the inner wall of the pipe. In addition, the L-shaped ring 703 has racks 704 distributed around its outer periphery extending into the hollow frame 701. A side chamber 702 is provided protruding from one side of the hollow frame 701. A gear 707 is rotatably installed in the side chamber 702. The gear 707 is driven by a second motor 709 inside the hollow frame 701. The gear 707 meshes with the rack 704. The second motor 709 drives the gear 707 to rotate. The L-shaped ring 703 drives the brushes 705 to rotate through the meshing rack 704. When the hollow frame 701 moves inside the pipe, the rotating brushes 705 can clean the inner wall of the pipe more efficiently.

[0029] In order not to affect the rotation of the L-shaped ring 703, a bearing 706 is provided between the water collecting sleeve 801 and the L-shaped ring 703 in the water spray component 8, so that the water spraying of the nozzle and the rotation of the brush 705 do not interfere with each other.

[0030] For cleaning the inner wall of a pipe, you can start from the middle of the inner wall and brush and rinse towards both ends. After rinsing stops, you can use a pipe endoscope to inspect the pipe, which improves cleaning efficiency and makes inspection more convenient.
