[0015] The present invention has the following beneficial effects:
[0016] 1. The present invention ventilates the interior of the serpentine condensation copper tube from one end thereof, thereby driving the propulsion assembly to push the polishing assembly to slide on the inner wall of the serpentine condensation copper tube. The gas passes through the propulsion assembly, the connecting shaft, the first connecting plate, the first bellows, the second connecting plate and the arc ring in sequence, and finally blows toward the impeller to rotate the impeller and drive the rotating ring to rotate, thereby driving the polishing protrusion on the rotating ring to rotate and propel the polishing on the inner wall of the serpentine condensation copper tube.
[0017] 2.

[0018] 3. The present invention arranges a seal so that the seal can slide closely against the inner wall of the serpentine condensation copper tube. When encountering the bent part of the serpentine condensation copper tube, the rubber pad will be slightly deformed, thereby squeezing the adjustment spring at the corresponding position. Since the gas inside the adjustment chamber remains unchanged, squeezing the rubber pad on one side will inevitably lead to the expansion of the rubber pad on the other side, thereby leading to the stretching of the adjustment spring at the corresponding position, thereby ensuring that the rubber pad is always closely against the inner wall of the serpentine condensation copper tube.
[0019] 4. The present invention is provided with a speed control component so that the wind speed of the gas blowing to the impeller remains unchanged. In the initial state, the electromagnet and the permanent magnet repel each other with the same polarity. At this time, the gas passes through the first speed control ring and the second speed control ring in sequence, and then blows to the impeller to drive the impeller to rotate, thereby driving the rotating ring to rotate and polish the inner wall of the serpentine condensation copper tube. When the camera captures the part with more protrusions on the inner wall of the serpentine condensation copper tube, the air pump reduces the air delivery speed. At the same time, the electromagnet and the permanent magnet attract each other with opposite polarity, so that the second speed control ring is close to the second connecting disk and surrounded by the side surface of the first speed control ring. At this time, the gas passes through the first speed control ring and blows directly to the impeller. Since the inner diameter of the first speed control ring is larger than the inner diameter of the second speed control ring, the gas flow rate increases, thereby keeping the impeller rotation speed unchanged from before the air pump reduces the air delivery speed.
[0020] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.
[0038] For specific embodiment 1, please refer to Figure 1-13 The present invention discloses a condenser tube finishing system for a condenser, comprising a serpentine condensing copper tube 1; a grinding assembly 2 is arranged on the inner wall of the serpentine condensing copper tube 1; the grinding assembly 2 comprises a first connecting plate 3 and a second connecting plate 4; a first corrugated tube 5 is connected between the first connecting plate 3 and the second connecting plate 4; the side surfaces of the first connecting plate 3 and the second connecting plate 4 are both slidably matched with the inner wall of the serpentine condensing copper tube 1; a connecting shaft 7 is fixed on the side surface of the first connecting plate 3; a hemispherical collecting frame 8 is fixed on the end of the connecting shaft 7; the side surfaces of the hemispherical collecting frame 8 are slidably matched with the inner wall of the serpentine condensing copper tube 1; an annular scraper 9 is fixed on the side surface of the hemispherical collecting frame 8; the annular scraper 9 is in contact with the inner wall of the serpentine condensing copper tube 1; the connecting shaft 7 is located inside the hemispherical collecting frame 8 and is evenly fixed in a circular array. A number of adsorption shafts 10; the adsorption shaft 10 and the inner wall of the serpentine condensation copper tube 1 are attracted by opposite charges; an arc ring 11 is fixed on the side of the second connecting plate 4; a swivel ring 12 is rotatably arranged on the side of the arc ring 11; a number of polished protrusions 13 are arranged on the outer peripheral side of the swivel ring 12; the peripheral side of the swivel ring 12 is slidably matched with the inner wall of the serpentine condensation copper tube 1; a number of impellers 14 are evenly fixed on the inner wall of the swivel ring 12 in a circular array; a rotating shaft 15 is connected between each impeller 14; an L-shaped mounting shaft 16 is fixed on the inner wall of the arc ring 11; a rotating groove 17 is penetrated at the end of the rotating shaft 15; the L-shaped mounting shaft 16 is rotatably matched with the rotating groove 17; a camera 18 is fixed on the end of the L-shaped mounting shaft 16; a propulsion component 19 is arranged on the hemispherical collection frame 8; the propulsion component 19 and the polishing component 2 are interconnected.
[0039] The working principle of this embodiment is: first, put the polishing component 2 and the propulsion component 19 into one end of the serpentine condensation copper tube 1, then put breathable cotton on the other end of the serpentine condensation copper tube 1, and then seal and ventilate from this end of the serpentine condensation copper tube 1, and the gas pushes the propulsion component 19 to slide along the inner wall of the serpentine condensation copper tube 1, and at the same time pushes the polishing component 2 to slide along the inner wall of the serpentine condensation copper tube 1.
[0040] During the sliding process of the grinding component 2 along the inner wall of the serpentine condensation copper tube 1, the gas first passes through the propulsion component 19, and then passes through the connecting shaft 7, the first connecting plate 3, the first bellows 5, the second connecting plate 4 and the arc ring 11, and finally blows to the impeller 14, so that the impeller 14 drives the rotating shaft 15 to rotate along the side of the L-shaped mounting shaft 16, and the rotating ring 12 to rotate along the side of the arc ring 11, thereby driving the grinding protrusion 13 on the rotating ring 12 to rotate and propel the inner wall of the serpentine condensation copper tube 1 to grind off the protrusion on the inner wall of the serpentine condensation copper tube 1. Part of the polished debris will be blown to the other end of the serpentine condensation copper tube 1 by the gas and collected inside the breathable cotton, and another part of the debris will remain on the inner wall of the serpentine condensation copper tube 1. When the annular scraper 9 on the grinding component 2 slides along the inner wall of the serpentine condensation copper tube 1, the cruel debris on the inner wall of the serpentine condensation copper tube 1 will be scraped into the hemispherical collection frame 8 and adsorbed on the side of the adsorption shaft 10.
[0041] In this embodiment, air is ventilated from one end of the serpentine condensation copper tube 1 to the interior thereof, thereby driving the propulsion component 19 to push the polishing component 2 to slide on the inner wall of the serpentine condensation copper tube 1. The gas passes through the propulsion component 19, the connecting shaft 7, the first connecting plate 3, the first bellows 5, the second connecting plate 4 and the arc ring 11 in sequence, and finally blows to the impeller 14 to cause the impeller 14 to rotate and drive the rotating ring 12 to rotate, thereby driving the polishing protrusion 13 on the rotating ring 12 to rotate and propel the polishing on the inner wall of the serpentine condensation copper tube 1.
[0042] At the same time, by setting the annular scraper 9, the hemispherical collecting frame 8 and the adsorption shaft 10, the debris polished by the polishing protrusion 13 can be scraped into the hemispherical collecting frame 8 by the annular scraper 9 and adsorbed on the side of the adsorption shaft 10, thereby improving the debris cleaning effect.
[0043] For specific embodiment 2, please refer to Figure 1-13 On the basis of the specific embodiment 1, the propulsion assembly 19 includes a first propulsion disk 20, a second propulsion disk 21 and a seal 22; a second bellows 23 is connected between the first propulsion disk 20 and the second propulsion disk 21; the side surfaces of the first propulsion disk 20 and the second propulsion disk 21 are both slidably matched with the inner wall of the serpentine condensation copper tube 1.
[0044] Specifically, the sealing member 22 includes a sealing disk 24; the diameter of the sealing disk 24 is smaller than the inner diameter of the serpentine condensation copper tube 1; a rubber pad 25 is provided for sealing the side surface of the sealing disk 24; the side surface of the rubber pad 25 is in contact with the inner wall of the serpentine condensation copper tube 1; the gap between the rubber pad 25 and the side surface of the sealing disk 24 forms an adjustment cavity 26; a number of adjustment springs 27 are evenly fixed in a circular array between the side surface of the sealing disk 24 and the rubber pad 25; the adjustment spring 27 is located inside the adjustment cavity 26.
[0045] Furthermore, a propulsion shaft 28 is fixed on the side of the first propulsion disk 20 and the second propulsion disk 21 at their axis; a hinged ball 29 is fixed on the end of the propulsion shaft 28; a fixing rod 30 is fixed on the side of the sealing disk 24 at its axis; a ball seat 31 is fixed on the end of the fixing rod 30 and the end of the connecting shaft 7; and the hinged ball 29 slides in cooperation with the inner wall of the adjacent ball seat 31.
[0046] Furthermore, a first air vent 32 is formed through the side surface of the articulated ball 29; the first air vent 32 penetrates the propulsion shaft 28; a second air vent 33 is formed through the inner wall of the ball seat 31; the second air vent 33 penetrates the fixing rod 30 and the sealing disk 24; a ventilation groove 34 is formed through the end of the connecting shaft 7; a driving groove 35 is formed through the side surface of the second connecting disk 4; the first air vent 32, the second air vent 33, the second bellows 23, the ventilation groove 34, the first bellows 5 and the driving groove 35 are all interconnected.
[0047] Furthermore, the end of the serpentine condensation copper tube 1 is sealed and connected to an air pump 6; the air pump 6 suction end is connected to the external environment, and its air outlet end is sealed and connected to the inside of the serpentine condensation copper tube 1; the air pump 6 suction end draws air from the external environment, and its air outlet end transports the gas into one end of the serpentine condensation copper tube 1, and transports the gas along the second air hole 33, the first air hole 32, the second bellows 23, the first air hole 32, the second air hole 33, the ventilation groove 34, the first bellows 5 and the driving groove 35 to the impeller 14, and is transported out from the other end of the serpentine condensation copper tube 1.
[0048] The working principle of this embodiment is as follows: gas is sucked from the external environment through the air pump 6 to ventilate the inside of the serpentine condensation copper tube 1, and the gas pushes the sealing plate 24 of the seal 22 and the rubber pad 25 to slide along the inner wall of the serpentine condensation copper tube 1. When encountering the bent part of the serpentine condensation copper tube 1, the rubber pad 25 will be slightly deformed, and then squeeze the adjustment spring 27 at the corresponding position. Since the gas inside the adjustment chamber 26 remains unchanged, squeezing the rubber pad 25 on one side will inevitably drive the rubber pad 25 on the other side to expand, and then drive the adjustment spring 27 at the corresponding position to stretch, thereby ensuring that the rubber pad 25 is always close to the inner wall of the serpentine condensation copper tube 1.
[0049] As the seal 22 slides along the inner wall of the serpentine condensation copper tube 1, it drives the fixing rod 30 and the ball seat 31 to move, and then drives the propulsion assembly 19 to slide along the inner wall of the serpentine condensation copper tube 1, so that the hinged ball 29, the propulsion shaft 28, the first propulsion disk 20, the second bellows 23 and the second propulsion disk 21 move. When encountering the bent part of the serpentine condensation copper tube 1, the hinged ball 29 slides along the inner wall of the ball seat 31 to adjust its position, so that the relative position of the grinding assembly 2 and the propulsion assembly 19 can adapt to the bent part of the inner wall of the serpentine condensation copper tube 1.
[0050] The gas enters the grinding assembly 2 through the second vent hole 33, the first vent hole 32, the second bellows 23, the first vent hole 32, and the second vent hole 33 in the serpentine condensing copper tube 1, and blows toward the impeller 14 along the vent groove 34 on the connecting shaft 7, the first bellows 5, and the driving groove 35 on the second connecting plate 4, so that the impeller 14 drives the rotating shaft 15 to rotate along the side of the L-shaped mounting shaft 16, and the rotating ring 12 to rotate along the side of the arc ring 11, thereby driving the grinding convex on the rotating ring 12. The inner wall of the serpentine condensation copper tube 1 is rotated and pushed to grind down the protrusions on the inner wall of the serpentine condensation copper tube 1. Part of the grinded debris will be blown to the other end of the serpentine condensation copper tube 1 by the gas and collected inside the breathable cotton, and the other part of the debris remains on the inner wall of the serpentine condensation copper tube 1. When the annular scraper 9 on the grinding component 2 slides along the inner wall of the serpentine condensation copper tube 1, the cruel debris on the inner wall of the serpentine condensation copper tube 1 is scraped into the hemispherical collection frame 8 and adsorbed on the side of the adsorption shaft 10.
[0051] In this embodiment, the sealing member 22 is arranged so that the sealing member 22 can slide closely against the inner wall of the serpentine condensation copper tube 1. When encountering the bent part of the serpentine condensation copper tube 1, the rubber pad 25 will be slightly deformed, thereby squeezing the adjustment spring 27 at the corresponding position. Since the gas inside the adjustment chamber 26 remains unchanged, squeezing the rubber pad 25 on one side will inevitably lead to the expansion of the rubber pad 25 on the other side, thereby leading to the stretching of the adjustment spring 27 at the corresponding position, thereby ensuring that the rubber pad 25 is always closely against the inner wall of the serpentine condensation copper tube 1.
[0052] For specific embodiment 3, please refer to Figure 1-13 On the basis of the specific embodiment 1 and the specific embodiment 2, a speed control component 36 is provided on the side of the second connecting disk 4; the speed control component 36 includes a fixing ring 37; the fixing ring 37 is fixed to the side of the second connecting disk 4 by fastening bolts; a first speed control ring 38 is fixed to the side of the fixing ring 37; a second speed control ring 39 is slidably provided on the side of the first speed control ring 38; the inner diameter of the first speed control ring 38 is smaller than the inner diameter of the second speed control ring 39; the side of the first speed control ring 38 is in contact with the inner wall of the driving groove 35.
[0053] Specifically, a plurality of limit slide grooves 40 are evenly arranged in a circular array on the side surface of the first speed control ring 38; a plurality of limit slide plates 41 are evenly arranged in a circular array on the inner wall of the second speed control ring 39; the limit slide plate 41 slidably cooperates with the limit slide groove 40; an electromagnet 42 is fixed on the side surface of the second connecting plate 4; and a permanent magnet 43 is fixed on the side surface of the second speed control ring 39.
[0054] The working principle of this embodiment is: when the polishing component 2 is in the process of polishing the protrusions on the inner wall of the serpentine condensation copper tube 1, the camera 18 takes real-time photos of the environment of the inner wall of the serpentine condensation copper tube 1. When the camera 18 takes a photo of the part with more protrusions on the inner wall of the serpentine condensation copper tube 1, the air pump 6 will reduce the air supply speed and thus slow down the movement speed of the polishing component 2 on the inner wall of the serpentine condensation copper tube 1, making the polishing component 2 stay in this position for a longer time, thereby prolonging the polishing time and improving the polishing effect.
[0055] When the gas velocity decreases, the rotation speed of the impeller 14 will also decrease accordingly. In order to keep the rotation speed of the impeller 14 unchanged, a speed control component 36 is provided.
[0056] In the initial state, the electromagnet 42 has the same magnetic properties as the permanent magnet 43, and the electromagnet 42 and the permanent magnet 43 will repel each other. At this time, the gas first passes through the first speed control ring 38 and then passes through the second speed control ring 39. The inner diameter of the second speed control ring 39 is larger than the inner diameter of the first speed control ring 38. After the gas is blown from the first speed control ring 38 to the second speed control ring 39, the gas flow rate will decrease, and then blow to the impeller 14 to drive the impeller 14 to rotate, and then drive the rotating ring 12 to rotate and polish the inner wall of the serpentine condensation copper tube 1.
[0057] When the camera 18 captures the part with more protrusions on the inner wall of the serpentine condensing copper tube 1, the air pump 6 reduces the air delivery speed. At the same time, the electromagnet 42 changes its magnetism to be opposite to the permanent magnet 43, and then the electromagnet 42 attracts the permanent magnet 43, so that the limiting slide plate 41 on the second speed control ring 39 slides along the inner wall of the limiting slide groove 40 on the first speed control ring 38, and finally sticks to the second connecting plate 4 and surrounds the side surface of the first speed control ring 38. At this time, the gas passes through the first speed control ring 38 and is directly blown to the impeller 14. Compared with blowing from the inner wall of the second speed control ring 39 to the impeller 14, the gas flow rate is greater, so that the rotation speed of the impeller 14 remains unchanged from before the air pump 6 reduces the air delivery speed.
[0058] In this embodiment, a speed control component 36 is provided to ensure that the wind speed of the gas blowing to the impeller 14 remains unchanged. In the initial state, the electromagnet 42 and the permanent magnet 43 repel each other with the same polarity. At this time, the gas passes through the first speed control ring 38 and the second speed control ring 39 in sequence, and then blows to the impeller 14 to drive the impeller 14 to rotate, thereby driving the rotating ring 12 to rotate and polish the inner wall of the serpentine condensation copper tube 1. When the camera 18 captures the part with more protrusions on the inner wall of the serpentine condensation copper tube 1, the air pump 6 reduces the air delivery speed. At the same time, the electromagnet 42 and the permanent magnet 43 attract each other with opposite polarity, so that the second speed control ring 39 is close to the second connecting plate 4 and surrounded by the side surface of the first speed control ring 38. At this time, the gas passes through the first speed control ring 38 and blows directly to the impeller 14. Since the inner diameter of the first speed control ring 38 is larger than the inner diameter of the second speed control ring 39, the flow rate of the gas increases, thereby keeping the rotation speed of the impeller 14 unchanged from before the air pump 6 reduces the air delivery speed.
