Description

Technical Field

[0001] This utility model relates to the field of industrial cleaning equipment technology, specifically to an ultrasonic cleaning device for the inner surface of aluminum alloy pipes. Background Technology

[0002] After long-term use, aluminum alloy pipes will accumulate impurities such as sludge and rust on their inner surface. Once these impurities solidify, they will form a hard grime on the inner surface of the aluminum alloy pipe. This grime will reduce the original diameter of the aluminum alloy pipe, decrease its transmission capacity, and in severe cases, even cause pipe blockage.

[0003] To address this problem, various pipe cleaning devices have been designed, among which ultrasonic pipe cleaning devices are one type. However, the existing ultrasonic pipe cleaning devices are generally only suitable for straight-through pipe structures, and the pipe needs to be fixed in position before ultrasonic cleaning. When ultrasonic cleaning is performed on pipes with right angles or U-shapes, the existing ultrasonic pipe cleaning devices cannot meet the position fixing requirements due to the special shapes of these pipes, and improvements are needed.

The specific technical solution is as follows:

[0005] This utility model discloses an ultrasonic cleaning device for the inner surface of aluminum alloy pipes.

A lead screw is threaded through the top of the base, with a handle at one end. Guide rods with the same extension direction as the lead screw are provided on the outer side walls of the base on both sides of the lead screw. A base is connected to the lead screw nut.

The limiting assembly is located outside the mating groove and abuts against the end of the first swing arm that is axially connected to the base.

[0007] As a further embodiment of the present invention, the limiting component includes a second connecting seat and a first screw. The second connecting seat is fixedly connected to the surface of the base of the mating groove. The first screw of the base is connected to the second connecting seat by means of thread engagement, and the end of the screw that extends through the second connecting seat abuts against the end of the first swing arm that is axially connected to the base.

[0008] As a further embodiment of this utility model, the supporting assembly includes a second swing arm, a second supporting wheel, and a second elastic member. One end of the second swing arm is connected to both sides of the mating groove via a rotating shaft.

[0009] As a further embodiment of this utility model, the limiting component is a second screw, and the base wall on the outer side of the second support wheel is provided with a screw hole.

[0030] Example 1:

[0031] This utility model discloses an ultrasonic cleaning device for the inner surface of aluminum alloy pipes, such as... Figures 1-8 and Figure 16As shown, the cleaning device includes a base 1, with a through hole 11 in the middle. A mating groove 12 is provided below the through hole 11. Supporting components 2 are connected to both sides of the mating groove 12 via rotating shafts. A limiting component 3 is provided on the outer side of the supporting component 2. A lead screw 4 is threaded through the top of the base 1. A handle 41 is provided at one end of the lead screw 4. Guide rods 5, extending in the same direction as the lead screw 4, are provided on the outer walls of the base 1 on both sides of the lead screw 4. A lead screw nut 42 is connected to a base 6. The two sides of the base 6 are fitted to the outer sides of the guide rods 5. At least one first connecting seat 61 is provided at the bottom of the base 6. A connecting component 7 is connected to the first connecting seat 61 via a rotating shaft. A clamp 8 is connected to the end of the connecting component 7 away from the first connecting seat 61 via a shaft connection. Several ultrasonic transducers 9 are arranged circumferentially around the clamp 8 with its central axis as the center.

[0032] It should be noted that during operation, the aluminum alloy pipe is first passed through the through hole 11 and placed on the surface of the support component 2. Then, the aluminum alloy pipe is passed through the clamp 8, and the clamp 8 is locked after passing through. During the locking process, the working end of the ultrasonic transducer 9 abuts against the outer wall of the aluminum alloy pipe. Water is then injected into the aluminum alloy pipe, and the ultrasonic transducer 9 is activated. The water inside the aluminum alloy pipe undergoes cavitation through ultrasonic waves, cleaning the inner wall of the pipe and achieving the effect of cleaning the inner surface of the aluminum alloy pipe. The support component 2 supports the aluminum alloy pipe, and the clamp 8 locks the pipe in place, thus stabilizing the aluminum alloy pipe during ultrasonic cleaning. The positioning of the components during the cleaning process prevents the ultrasonic transducer 9 from failing to transmit vibrations into the aluminum alloy pipe due to displacement, ensuring that the inner surface of the aluminum alloy pipe receives ultrasonic cleaning. Furthermore, the support assembly 2 and clamp 8 can be adjusted according to the diameter of the aluminum alloy pipe, and the position of the clamp 8 can also be adjusted according to the shape of the aluminum alloy pipe. For example, by rotating the screw 4 via the handle 41, the position of the base 6 connected to the screw 4 outside the base 1 changes, thereby adjusting the position of the clamp 8. This allows the position of aluminum alloy pipes of different shapes and sizes to be fixed on the cleaning device, enabling it to meet the cleaning needs of aluminum alloy pipes of various shapes and sizes.

[0033] It needs to be further explained that, such as Figures 3-8As shown, the supporting assembly 2 includes a first swing arm 21, a first supporting wheel 22, and a first elastic element 23. One end of the first swing arm 21 is connected to both sides of the mating groove 12 via a pivot, and the first supporting wheel 22 is connected to the other end of the first swing arm 21 via a pivot. The two first supporting wheels 22 are directly opposite each other in the through hole 11, and their proximal ends are both conical. The base 1 outside the first swing arm 21 is provided with a groove 13. The first elastic element 23 is fixedly connected in the groove 13 and abuts against the end of the first swing arm 21 near the first supporting wheel 22. The limiting assembly 3 is located outside the mating groove 12 and abuts against the end of the first swing arm 21 that is axially connected to the base 1.

[0034] The first swing arm 21 can swing around its end connected to the shaft of the base 1. The first elastic element 23 is a compression spring that abuts against the end of the first support wheel 22 on the first swing arm 21. With the limiting component 3 limiting the other end of the first swing arm 21, the position of the two first swing arms 21 in the through hole 11 can be adjusted, so that the included angle formed by the near ends of the two first support wheels 22 changes. The distance between the end faces of the two first support wheels 22 supporting the aluminum alloy pipe changes, so that the two first support wheels 22 can adapt to support aluminum alloy pipes of different diameters, so as to ensure that the position of the aluminum alloy pipe can be maintained. Moreover, using the first support wheel 22 to support the aluminum alloy pipe can facilitate the aluminum alloy pipe to continue to move under external force after passing through the through hole 11, so that the part of the aluminum alloy pipe on the clamp 8 side can move, thereby facilitating the clamp 8 to lock the aluminum alloy pipe.

[0035] Specifically, such as Figure 7 and Figure 8 As shown, the limiting component 3 includes a second connecting seat 31 and a first screw 32. The second connecting seat 31 is fixedly connected to the surface of the base 1 of the mating groove 12. The first screw 32 of the base 1 is connected to the second connecting seat 31 by means of thread engagement, and the end of the screw 32 that extends out of the second connecting seat 31 abuts against the end of the first swing arm 21 that is axially connected to the base 1.

[0036] The first elastic element 23 acts on the elastic force of the first swing arm 21, causing the first swing arm 21 to fit tightly against the end of the first screw 32. By turning the first screw 32, the first screw 32 can be moved within the second connecting seat 31, thus adjusting the position of the first swing arm 21. The longer the portion of the first screw 32 enters the second connecting seat 31, the closer the end of the first swing arm 21 connecting to the first support roller 22 is to the groove 13 within the through hole 11. This increases the distance between the two first support rollers 22, allowing them to support a larger amount of aluminum. The larger the diameter of the alloy pipe, the shorter the portion of the first screw 32 that enters the second connecting seat 31, the further the end of the first swing arm 21 connected to the first support wheel 22 is from the groove 13 in the through hole 11, the smaller the distance between the two first support wheels 22, and the smaller the diameter of the aluminum alloy pipe that the two first support wheels 22 can support. Through the above-mentioned adjustment operation of the limiting component 3, the first swing arm 21 can be limited, thereby changing the position of the first support wheel 22 in the through hole 11, so as to adjust the diameter of the aluminum alloy pipe supported by the supporting component 2.

[0037] It needs to be further explained that, such as Figure 16 As shown, the connecting assembly 7 includes a connecting plate 71 and a connecting frame 72. One end of the connecting plate 71 is connected to the first connecting seat 61 by bolts. The connecting plate 71 is provided with a sliding groove 711. One end of the connecting frame 72 is provided with at least one fourth connecting seat 721. The end of the fourth connecting seat 721 that is furthest from the connecting plate 71 is connected to the connecting plate 71 by bolts that fit into the sliding groove 71. The clamp 8 is connected to the end of the connecting frame 72 by a rotating shaft.

[0038] The clamp 8 is connected to the first connecting seat 61 via the connecting plate 71, allowing it to rotate around the end of the connecting plate 71 connected to the first connecting seat 61 as the rotation center. The clamp 8 can also slide within the slide groove 711 via the bolt on the fourth connecting seat 721, allowing it to move along the slide groove 711 with the bolt on the fourth connecting seat 721 as the base point. It can also rotate around the bolt on the fourth connecting seat 721 as the rotation center. Furthermore, the clamp 8 can rotate around the end of its shaft connected to the connecting frame 72. These various clamp 8 position adjustment methods allow for the adjustment of the clamp 8's position, enabling it to lock onto non-straight-through aluminum alloy pipes, such as those in right-angle or U-shaped configurations, ensuring the stability of the aluminum alloy pipe's position during ultrasonic cleaning.

[0039] Specifically, such as Figure 16 As shown, one of the ring petals of the clamp 8 is axially connected to the end of the connecting frame 72. The ring petal is provided with a plurality of mating holes 81 for mating with the ultrasonic transducer 9. The ultrasonic transducer 9 penetrates the inner wall of the ring petal.

[0040] The ultrasonic transducers 9 are arranged along the circumference of the annular lobe, which allows the ultrasonic transducers 9 to contact the aluminum alloy pipe in multiple directions outside the aluminum alloy pipe to transmit vibration. The contact between the multiple ultrasonic transducers 9 and the aluminum alloy pipe can also stabilize the position of the aluminum alloy pipe. When the ultrasonic transducers 9 malfunction, they can be removed from the mating hole 81 for replacement.

[0041] Example 2:

[0042] The difference between this embodiment and Embodiment 1 is that, Figures 9-16 As shown, the supporting assembly 2 includes a second swing arm 24, a second supporting wheel 25, and a second elastic element 26. One end of the second swing arm 24 is connected to both sides of the mating groove 12 via a pivot, and the second supporting wheel 25 is connected to the other end of the second swing arm 24 via a pivot. The two second supporting wheels 25 are directly opposite each other in the through hole 11, and their proximal ends are both conical. A third connecting seat 27 is provided on the surface of the base 1 outside the mating groove 12. The second elastic element 26 is fixedly connected to the end of the third connecting seat 27 near the end of the second swing arm 24 and abuts against the end of the second swing arm 24 that is axially connected to the base 1. The limiting assembly 3 is provided on the wall surface of the base 1 near the side of the second supporting wheel 25.

[0043] It should be noted that the second swing arm 24 can swing around its end connected to the base 1 shaft. The second elastic element 26 is a compression spring, which abuts against the end of the second swing arm 24 that is connected to the base 1 shaft. Combined with the limiting component 3's limiting effect on the end of the first swing arm 21 connected to the second support roller 25, the positions of the two first swing arms 21 within the through hole 11 can be adjusted, changing the included angle formed by the proximal ends of the two second support rollers 25, and altering the distance between the end faces of the two second support rollers 25 supporting the aluminum alloy pipe. The structure of the support component 2 and the limiting component 3 used in this embodiment... The arrangement of the supporting component 2 and the limiting component 3 on the base 1 differs from that in Embodiment 1, but the technical effect achieved in this embodiment is the same as that achieved in Embodiment 1. Specifically, the two second supporting wheels 25 can adapt to aluminum alloy pipes of different diameters to support them, so as to ensure that the position of the aluminum alloy pipe can be maintained. Moreover, using the second supporting wheels 25 to support the aluminum alloy pipe makes it convenient for the aluminum alloy pipe to continue to be pulled by external force after passing through the through hole 11, so that the part of the aluminum alloy pipe on the clamp 8 side can move, thereby making it convenient for the clamp 8 to lock the aluminum alloy pipe.

[0044] Specifically, such as Figure 11 and Figure 12As shown, the limiting component 3 is a second screw 33. The base 1 wall outside the second support wheel 25 is provided with a screw hole 14. The second screw 33 is fitted into the screw hole 14, and one end of it abuts against the end of the second swing arm 24 near the second support wheel 25.

[0045] Unlike Embodiment 1, in this embodiment, the limiting component 3 controls the position of the second swing arm 24 by adjusting the length of the second screw 33 entering the through hole 11 of the base 1. The longer the portion of the second screw 33 entering the through hole 11, the smaller the distance between the two second support rollers 25, and the smaller the diameter of the aluminum alloy pipe that the two second support rollers 25 can support. Conversely, the shorter the portion of the second screw 33 entering the through hole 11, the larger the distance between the two second support rollers 25, and the larger the diameter of the aluminum alloy pipe that the two second support rollers 25 can support. Through the above-mentioned adjustment operation of the limiting component 3, the second swing arm 24 can be limited, thereby changing the position of the second support rollers 25 in the through hole 11, so as to adjust the diameter of the aluminum alloy pipe supported by the support component 2. The technical effect achieved is the same as that achieved in Embodiment 1.

[0046] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
