Description

Technical Field

[0001] The utility model relates to the technical field of inner cavity cleaning, in particular to an inner cavity cleaning device for tubular parts. Background Art

[0002] Thoroughly cleaning the interior of tubular components is crucial. This not only impacts the subsequent performance of the component, but also directly affects the operating efficiency and stability of the entire equipment. Cleaning the interior of tubular components primarily involves meticulously cleaning the interior, removing any dirt, residue, rust, and other debris to ensure absolute cleanliness.

[0003] During the internal cavity cleaning process, a variety of methods and tools may be used, such as high-pressure water guns, detergents, brushes, and compressed air. First, use a high-pressure water gun to flush the inner cavity to remove most dirt and residue. Then, use detergent and a brush to carefully clean the inner cavity. Particularly for areas that are difficult to rinse with water, manual cleaning with a brush is required. Finally, use compressed air to blow out the moisture and detergent in the inner cavity to ensure that the inner cavity is dry. In addition, for some tubular components made of special materials, specialized cleaning equipment and methods may be required to avoid damage to their surface.

[0004] In the patent "A Portable Pipeline Cleaning Device" (publication number CN209697654U, hereinafter referred to as prior art 1), a pipeline cleaning device is disclosed. In prior art 1, two pairs of crawling wheels are arranged on a rotating shaft to help the device move and support. The rotating shaft is driven by a drive motor, and the drive motor drives the crawling wheels to make the device as a whole move forward in the pipeline, and the rotating drum is rotated by the rotating motor so that the bristles brush the inner wall of the pipeline. The cleaning device in prior art 1 uses two pairs of crawling wheels arranged front and back. Since the cleaning is carried out inside the pipeline, the two pairs of crawling wheels arranged front and back are not conducive to the movement of the device as a whole. When the two pairs of crawling wheels arranged front and back come into contact with the inner wall of the pipeline, the contact between them is almost point contact, and the friction force is insufficient, making it difficult to move. In addition, the support of the two pairs of crawling wheels arranged front and back on the overall device is insufficient, which may cause the weight of the cleaning end to be heavier, resulting in sagging, resulting in poor cleaning effect. Utility Model Content

[0005] In view of this, an embodiment of the present invention provides an inner cavity cleaning device for tubular components, so as to solve the problem that the pipeline cleaning device in the prior art has difficulty in moving inside the pipeline, resulting in poor cleaning effect.

[0017] The interior of the cleaning machine's main body is hollow, ensuring structural stability while providing ample space for the drive motor and cleaning components, reducing the overall weight of the device. By providing at least three sets of auxiliary movement mechanisms, evenly spaced at regular angles on the exterior surface of the cleaning machine's main body, the device is more stable during movement and less likely to tip over. Each set of auxiliary movement mechanisms is attached to the main body via a base, further enhancing the device's stability. The rollers within the auxiliary movement mechanisms ensure smoother movement, reducing friction with the ground and improving operational efficiency. The even distribution of the rollers also ensures the device's balance during movement, preventing tipping due to an unstable center of gravity.

The rational structure of the entire device allows for easy cleaning of the interior cavities of tubular components, improving operational efficiency. Furthermore, the stability, balance, and convenience of the device are fully guaranteed. BRIEF DESCRIPTION OF THE DRAWINGS

[0027] Example 1

[0028] See Figure 1, an embodiment of the utility model provides an inner cavity cleaning device for tubular parts, comprising a cleaning machine main body 100 and an auxiliary moving mechanism provided on the outer surface of the cleaning machine main body 100. The auxiliary moving mechanism carries the cleaning machine main body 100 to move in the pipe to be cleaned. The auxiliary moving mechanism is attached to the body of the moving mechanism and moves by the movement of the auxiliary moving mechanism. The cleaning machine main body 100 first serves as a carrying component, which can not only carry the moving mechanism but also carry the parts to be cleaned. The auxiliary moving mechanism is attached to the side body of the cleaning machine main body 100, and the parts to be cleaned are installed at both ends of the cleaning machine main body 100 for cleaning.

[0029] See Figure 1 and Figure 2 The cleaning machine body 100 is composed of a first shell 110 and a second shell 120; the interior of the cleaning machine body 100 is a hollow space. The cleaning machine body 100 is composed of two parts, and its interior is a hollow space. After the cleaning components are installed in the cleaning machine body 100, the interior of the cleaning machine body 100 remains sealed. This seal not only isolates dirt inside the pipe to be cleaned from the interior of the cleaning machine body 100, but also prevents sewage from entering the cleaning machine body 100 and damaging the components installed therein.

[0030] See Figure 1 and Figure 2 One end of the cleaning machine body 100 is provided with an opening 130, and the opening 130 is sealed after the various components inside the cleaning machine body 100 are installed. A driving motor is provided inside the cavity of the cleaning machine body 100, and the output shaft of the driving motor extends from the inside of the opening 130. When the output shaft of the driving motor extends from the inside of the opening 130, it is sealed to prevent dirt and sewage from entering. The cleaning machine body 100 is provided with a cleaning component through the end of the output shaft. Furthermore, a component that drives the auxiliary moving mechanism can be set in the inner cavity so that it can automatically clean the inner cavity of the pipeline. By arranging a driving motor and a battery in the inner cavity, the various components of the cleaning machine body 100 are driven, so that it can automatically clean and move. The cleaning component is installed through the output shaft and is connected to the output shaft in a transmission manner. The rotation of the output shaft drives the cleaning component to rotate, and an auxiliary connection can be made between them through a coupling 212. The cleaning component is connected to the output shaft via a coupling 212 ; when the driving motor drives the output shaft to rotate, the cleaning component is driven to rotate via the coupling 212 .

[0031] See Figure 1The auxiliary moving mechanism is provided with at least three groups. The three groups of supports are relatively stable when arranged inside the pipe. The cross-sectional circle of the pipe just forms the circumscribed circle of the three groups of supports, so that the cleaning machine components can stably perform cleaning work inside the cleaning machine. If two groups or one group are provided, the support is unstable, and the cleaning machine body 100 may not be able to perform comprehensive cleaning or stable movement when cleaning. Furthermore, when one group is provided, the auxiliary moving mechanism is provided at the bottom position of the cleaning machine body 100, driving the cleaning machine body 100 to move. At this time, the auxiliary moving mechanism has the problem of insufficient friction between the inner wall of the pipe and cannot move forward.

[0032] When two groups are provided, they are placed at intervals of 120° on both sides of the cleaning machine body 100 near the bottom. The friction force is higher than when one group is provided, but it will be partially offset by the friction force generated during cleaning, resulting in poor cleaning effect. Three groups of auxiliary movement mechanisms are placed at even angles on the outer surface of the cleaning machine body 100, and the inner wall of the pipe is the circumscribed circle of the three groups of auxiliary movement mechanisms. In this case, the friction and support of the auxiliary movement mechanisms on the inner wall of the pipe are sufficient to support the cleaning machine body 100 to move forward.

[0033] Furthermore, each set of auxiliary moving mechanisms has a certain length, and the three sets of auxiliary moving mechanisms can independently support the cleaning machine body 100 so that the problem of head sagging does not occur.

[0034] See Figure 4 , the auxiliary moving mechanism is arranged on the cleaning machine main body 100 through a base 300. The auxiliary moving mechanism is installed on the cleaning machine main body 100 through the base 300 as a medium. Since the auxiliary moving mechanism works in a complex environment inside the pipeline, it is more likely to be damaged. In order to avoid replacing the cleaning machine main body 100 together with the auxiliary moving mechanism after it is damaged, the auxiliary moving mechanism is arranged on the base 300, which makes it easier to install, disassemble and replace. Its connection adopts a detachable auxiliary moving mechanism including a moving body 410; a number of evenly distributed rollers 411 are arranged inside the moving body 410. It moves by means of a number of rollers 411 arranged on the moving body 410, and by setting more rollers 411, it has more contact with the inner wall of the pipeline, greater friction, and easier movement.

[0035] Example 2

[0036] See Figure 1The present invention provides an inner cavity cleaning device for tubular components, wherein the cross-section of the cleaning machine body 100 is a regular polygon. Furthermore, according to practical applications, when the cross-section of the cleaning machine body 100 is a regular polygon, the support arrangement for the cleaning machine body 100 is more convenient, and the support effect is better. Furthermore, when the cross-section of the cleaning machine body 100 is a regular polygon, the installation of the auxiliary movement mechanism is also more convenient, and no arc-shaped installation is required, making the device easier to manufacture.

[0037] Furthermore, the number of sides of the regular polygon is set to an even number. When the number of sides of the regular polygon is set to an even number, it is easier to determine the installation positions of multiple sets of auxiliary movement devices. Preferably, when the present invention uses three sets of auxiliary movement devices for installation, the installation positions can be determined by adjacent faces.

[0038] The cleaning machine body 100 is designed to have a precise regular polygonal cross-section. Furthermore, when considering actual application scenarios, it is particularly important to choose a regular polygon as the cross-sectional shape of the cleaning machine body 100. Such a design provides great convenience for the support structure of the cleaning machine body 100, making the support process simple and effective, thereby significantly improving the stability and efficiency of the support. In addition, when the cross-section of the cleaning machine body 100 adopts a regular polygonal design, the installation of the auxiliary moving mechanism also becomes easier, without having to consider the complex arc processing and installation method, which simplifies the processing process of the device.

[0039] Furthermore, the number of sides of the regular polygon of the present invention is specifically set to an even number. This selection provides a clear method for determining the installation position of multiple sets of auxiliary movement devices, greatly improving the accuracy and efficiency of installation. In particular, when three sets of auxiliary movement devices are used for installation, the installation position can be directly determined by adjacent surfaces, further simplifying the installation process and improving the convenience of installation. This design not only optimizes the structure of the cleaning machine body 100, but also improves its overall operating efficiency and stability.

[0040] See Figure 1 and Figure 3 The end of the cleaning machine body 100 away from the opening 130 is closed, and a connecting flange 140 is provided on the closed end of the cleaning machine body 100. Through the configuration of the connecting flange 140, an external power device or a traction device can be connected to assist the cleaning machine body 100 in positioning or to retract the cleaning machine body 100 when the cleaning machine body 100 loses power.

[0041] Described cleaning machine main body 100 is designed to be closed and set at an end away from described opening 130, thereby forms a complete structure.In this closed end, a connecting flange 140 is specially designed. The effect of this connecting flange 140 is to provide a kind of interface, so that be connected with other equipment. Through this connecting flange 140, can easily external various power equipment, such as motor, engine etc., thereby provide necessary power for cleaning machine main body 100. Simultaneously, also can connect traction device, such as chain, rope etc., so that cleaning machine main body 100 is carried out position adjustment or control. Like this, when cleaning machine main body 100 loses power, can be taken back by traction device, avoid pipeline damage or the problem that cannot be taken back because of power failure. By arranging connecting flange 140 at the closed end of cleaning machine main body 100, not only can improve its working efficiency, can also enhance its operability and safety.

[0042] See Figure 4 The rollers 411 are wrapped with rubber tracks 412 ; and the outer surface of the rubber tracks 412 is provided with a plurality of anti-skid protrusions 413 at intervals.

[0043] See Figure 4 , a circle of rubber tracks 412 covers the periphery of multiple rollers 411. On the outer surface of the rubber tracks 412, many anti-skid protrusions 413 are evenly distributed at certain intervals. These protrusions are designed to increase the friction of the contact surface between the rubber tracks 412 and the inner wall of the pipe, so that the rollers 411 can maintain good grip performance in various complex pipe environments and prevent slipping. Such a setting is particularly suitable for occasions requiring high stability and reliability, ensuring that the combination of rubber tracks 412 and rollers 411 can provide sufficient traction on heavy loads or easily slipping surfaces, ensuring the safety and efficiency of operations. In addition, the shape and size of these protrusions are adapted to the inner wall of the pipe; ensuring that the best anti-skid effect can be achieved under the conditions of use of the inner wall of the pipe, while also taking into account the wear resistance and durability of the rubber tracks 412 to ensure that it can still maintain good working condition after long-term use.

[0044] See Figure 4 The rollers 411 at both ends of the mobile body 410 are equipped with transmission teeth 415 that mesh with the transmission grooves 414 provided within the rubber track 412. The mobile body 410 is provided with rollers 411 at both ends. These rollers 411 are equipped with transmission teeth 415 that can precisely mesh with the transmission grooves 414 embedded within the rubber track 412. These transmission teeth 415 ensure the stability and reliability of the mobile body 410 during movement, enabling effective power transmission between the rubber track 412 and the rollers 411, ensuring that the mobile body 410 can move efficiently within the inner wall of the pipe.

[0045] See Figure 1 and Figure 4 The two ends of the mobile body 410 are respectively connected to the base 300 through a pair of support rods 420; the base 300 is also provided with a first buffer mechanism and a second buffer mechanism; the first buffer mechanism includes a first connecting seat 511 and a second connecting seat 512, which are respectively arranged at the two ends of the other part of the base 300 where the auxiliary moving mechanism is set. The two ends of the mobile body 410 are connected to the base 300 through a pair of support rods 420. Two sets of buffer mechanisms are also specially set on this base 300, namely the first buffer mechanism and the second buffer mechanism, to increase the stability and safety of the entire system. The first buffer mechanism is mainly composed of a first connecting seat 511 and a second connecting seat 512, and these two connecting seats are respectively located at the two ends of the other part of the base 300 where the auxiliary moving mechanism is set. Such a design not only ensures the stability of the mobile body 410 during movement, but also reduces the impact and vibration caused by movement, thereby improving the service life and efficiency of the entire system.

[0046] See Figure 1 The base 300 is provided with a rectangular through-hole 310, through which the second connecting seat 512 is connected to the base 300. A first buffer member 513 is provided between the first connecting seat 511 and the second connecting seat 512. The base 300 is a sturdy component, with a rectangular through-hole designed to meet specific structural and functional requirements. The shape and size of the rectangular through-hole 310 allow the second connecting seat 512 to pass smoothly through and establish a secure connection with the base 300. This connection method not only ensures the stability of the overall structure but also improves the coordination between the components. A first buffer member 513 is designed between the first connecting seat 511 and the second connecting seat 512. This buffer member provides excellent filling and connection functions, absorbing thermal expansion and contraction and deformation caused by temperature, humidity, and other external factors, thereby reducing the stress and pressure caused by these deformations and ensuring a reliable connection. Furthermore, the first buffer member 513 can disperse stress caused by uneven force at the connection, thereby improving the service life and reliability of the connection.

[0047] Preferably, the two ends of the second buffer mechanism are respectively connected to the second connecting seat 512 and the body of the mobile body 410; the second buffer mechanism is provided with a spring 521. The first buffer mechanism is provided with a damper 514; the second connecting seat 512 moves based on the rectangular through hole 310.

[0048] The second buffer mechanism is located between the two endpoints, with its ends tightly connected to the second connecting base 512 and the body of the mobile body 410, respectively. This structural design enables the second buffer mechanism to effectively buffer and absorb impacts or vibrations during movement, thereby protecting the stability and safety of the body and connecting base. A spring 521 is installed within the second buffer mechanism. This spring 521 plays a critical role, adjusting its elasticity to achieve a buffering effect based on the movement of the mobile body 410.

[0049] See Figure 1 The first buffer mechanism is equipped with a damper 514. The damper 514 is a device that applies resistance to a moving object, thereby slowing its movement. During the movement of the mobile body 410, the damper 514 provides a buffer based on the speed of movement, making the movement of the mobile body 410 smoother and more stable, and preventing shaking or vibration caused by excessive speed or acceleration.

[0050] Furthermore, the second connection base 512 moves based on the rectangular through-hole 310. This design makes the second connection base 512 more stable and smooth during movement, avoiding shaking or vibration of the device caused by the movement of the connection base. Furthermore, the design of the rectangular through-hole 310 also allows the connection base to move more widely, thus meeting the needs of pipeline usage scenarios.

[0051] See Figure 1 , the two ends of the cleaning machine body 100 are supported by cleaning components and at least three groups of auxiliary moving mechanisms respectively. The two ends of the cleaning machine body 100 are stably supported by special cleaning components and at least three groups of auxiliary moving mechanisms. These supporting structures not only ensure the stability of the cleaning machine during operation, but also avoid unnecessary shaking and vibration. The cleaning components are responsible for directly contacting the inner wall of the pipe, and cleaning by rotating and generating friction with the inner wall of the pipe, effectively removing stains and residues on the surface. Furthermore, cleaning agents can be attached to the cleaning components to assist in cleaning. The auxiliary moving mechanisms play a coordinating and auxiliary role. They are responsible for adjusting the position of the cleaning components so that they can clean inside the pipe, so that the cleaning process can be carried out more accurately and efficiently. Not only does it improve the cleaning efficiency, but it also improves the reliability and safety of the entire cleaning process.

[0052] Example 3

[0053] See Figure 2The embodiment of the utility model provides an inner cavity cleaning device for tubular parts, wherein the cleaning component is a roller brush 610, and its overall structure is roller-shaped. A roller is provided inside as the main body, and a component that contacts the inner wall of the pipe during cleaning is provided outside, which is generally made of cylindrical materials such as PA, PBT, PP and PET. When in use, the roller brush 610 is driven by a driving motor and starts to rotate, and cleans the component that contacts the inner wall of the pipe during cleaning. The component that contacts the inner wall of the pipe during cleaning can be attached with cleaning agents and other substances to assist in cleaning. After cleaning, the inside of the pipe can be flushed with a high-pressure water gun. The roller brush 610 can also be attached to wipe the inside of the pipe after cleaning once, and cotton fabric can be provided on the roller to perform a second cleaning on the inner wall of the pipe. It has an excellent cleaning effect and can effectively remove dirt and impurities on the inner wall of the pipe.

[0054] Example 4

[0055] See Figure 3 The present invention provides a device for cleaning the inner cavity of a tubular component. The cleaning component is an annular brush 620. The outer ring of the annular brush 620 is provided with relatively dense brush strips. The high-speed rotation of the drive motor drives the annular brush 620, generating friction between the brush strips and the inner wall of the pipe, thereby cleaning the inner wall of the pipe. Generally, the first cleaning of the inner wall of the pipe is a quick one-time cleaning.

[0056] Example 5

[0057] See Figure 4 The present invention provides a device for cleaning the inner cavity of a tubular component, wherein the cleaning component is a scraper brush 630. The scraper brush 630 is a cylindrical body with a plurality of scrapers. If there are some substances adhering to the inner wall of the pipe that cannot be cleaned by more gentle cleaning methods, the scrapers provided on the scraper brush 630 will scrape them off.
