[0002] In the field of industrial pipelines, spiral pipes are widely used in water supply, oil and gas transportation, chemical industry and other fields due to their high strength, easy processing and other characteristics. However, continuous spiral welds formed during the manufacturing process of spiral pipes (usually using full-weld technology) are prone to residual impurities such as welding slag and oxides, so spiral pipes need to be cleaned.

[0015] The advantages and positive effects of the present invention are:

[0016] (1) By allowing gas to enter the gas transmission channel in the double-channel conduit, delivering the gas to the blowtorch through the gas transmission holes, and operating the blowtorch to ignite, the fire is sprayed from the blowtorch onto the inner wall of the spiral pipe. Thus, the inner wall of the spiral pipe is preheated by the flame ejected from the blowtorch, making it easier for impurities such as rust layers and oil stains on the inner wall of the spiral pipe to fall off, thereby reducing the cleaning difficulty of the spiral pipe.

[0017] (2) By rotating all the bristles to clean the inner wall of the spiral pipe and making all the bristles contact the weld from the side, all the bristles are inserted straight into the weld on the inner wall of the spiral pipe, reducing the phenomenon that all the bristles detach from the weld during rotation, thereby improving the cleaning effect of the spiral pipe.

[0018] (3) Through the setting of the notch, the impurities cleaned by the bristles can fall from the notch, reducing the accumulation of impurities on the cleaning plate. And since the cleaning plate is set in a spiral shape, when the cleaning plate moves leftward and rotates along the spiral pipe, the cleaning plate can move and rotate along the trajectory of the weld, thereby improving the cleaning effect of the weld on the inner wall of the spiral pipe.

[0019] (4) By making the knocking hammer rotate reciprocally to hammer the inner wall of the spiral pipe, the stubborn stains on the inner wall of the spiral pipe are shaken off. At the same time, it cooperates with all the bristles, thereby improving the cleaning effect of the spiral pipe.

[0020] (5) By making all the bristles expand and spread outwards, more bristles can contact the weld on the inner wall of the spiral pipe from different angles, and the bristles can be deformed by the extrusion of the weld, thereby increasing the friction between the bristles and the weld on the inner wall of the spiral pipe, achieving a better cleaning effect.

[0021] (6) By using the abrasive papers on the two elastic plates to polish the inner wall of the spiral pipe, the cleaning effect of the spiral pipe is further improved. Then, the inner wall of the spiral pipe is flushed with water, and the water can form a vortex on the inner wall of the spiral pipe, further enhancing the flushing effect on the inner wall of the spiral pipe.

[0035] A vision sensor is provided on the fixed frame 1 for detecting the inner side of the spiral pipe 3.

[0036] The cleaning plate 206 is arranged in a spiral shape for better cleaning the welds on the inner side of the spiral pipe 3.

[0037] A number of notches 2061 are opened on the cleaning plate 206, and each group of bristles 207 is arranged at the edge of a corresponding notch 2061 for quickly discharging the impurities cleaned inside the spiral pipe 3.

[0038] All the bristles 207 are made of metal material to improve the service life of the bristles 207.

[0039] All the nozzles 2081 are distributed in a spiral shape as a whole and are inclined in a direction away from the cleaning plate 206, so that the sprayed water forms a vortex and moves away from the cleaning plate 206, thereby preventing the water flow from affecting the normal operation of the device.

[0040] It also includes a support plate Ⅰ301, a motor 302, a ratchet 303, a mounting frame 304, a connecting shaft Ⅱ305, a ratchet 306, a hammer 307 and an elastic member Ⅰ3071; the transmission shaft Ⅰ203 is connected to the support plate Ⅰ301; the upper and lower ends of the support plate Ⅰ301 are each equipped with a pulley; the motor 302 is installed on the support plate Ⅰ301; the output shaft of the motor 302 is fixedly connected to the ratchet 303; two mounting frames 304 are fixedly connected to the support plate Ⅰ301; each mounting There is a connecting shaft II 305 rotatably connected to the frame 304; a ratchet 306 is fixedly connected to each connecting shaft II 305; all ratchet teeth 306 are engaged with the ratchet wheel 303; a striking hammer 307 is fixedly connected to each connecting shaft II 305; two elastic members I 3071 are sleeved on the outer side of each connecting shaft II 305, and the elastic member I 3071 is a torsion spring, one end of the elastic member I 3071 is fixedly connected to the mounting frame 304, and the other end of the elastic member I 3071 is fixedly connected to the striking hammer 307.

[0041] The upper portion of the striking hammer 307 is arranged in a circular ring shape, so as to reduce the damage caused by the striking hammer 307 to the spiral tube 3 .

[0042] The driving assembly includes a motor 201, a bevel gear I 202 and a bevel gear II 204; a chamber is provided on the fixed frame 1, and the motor 201 is fixedly connected in the chamber of the fixed frame 1; the output shaft of the motor 201 is fixedly connected to the bevel gear I 202; the transmission shaft I 203 is fixedly connected to the bevel gear II 204; the bevel gear II 204 is meshed with the bevel gear I 202.

[0043] The external pump for water delivery is connected to the dual-channel water delivery channel in advance, and the external pipeline for gas delivery is connected to the dual-channel gas delivery channel. When cleaning the spiral tube 3, the fixing frame 1 and all the driving wheels 2 are manually placed into the inner wall of the spiral tube 3, and the angles of all the driving wheels 2 are adjusted so that all the driving wheels 2 can resist the inner wall of the spiral tube 3, thereby making the driving wheels 2 remain stable during the movement, and at the same time, all the connected parts are moved to the inner wall of the spiral tube 3.

[0044] Because traditional scrapers or rotating brush heads are difficult to fit the geometric features of the spiral weld on the inner wall of the spiral tube 3, the weld protrusions are not cleaned thoroughly, and the anti-corrosion coating on the inner wall is easily damaged. In addition, stubborn stains on the inside of the spiral tube 3 are difficult to clean quickly and thoroughly.

[0045] To solve the above problems, by controlling the opening of the gas pipeline of the peripheral device, gas is made to enter the gas transmission channel in the double-channel conduit 210, and the gas is transported to the blowtorch 209 through the gas transmission holes 2103, and the blowtorch 209 is made to operate and ignite, so that the flame is sprayed from the blowtorch 209 onto the inner wall of the spiral tube 3, and thus the inner wall of the spiral tube 3 is preheated by the flame sprayed from the blowtorch 209, so that impurities such as rust layers and oil stains on the inner wall of the spiral tube 3 are more likely to fall off, thereby reducing the cleaning difficulty of the spiral tube 3. Then, the motor 201 is controlled to start. The rotation of the output shaft of the motor 201 drives the bevel gear I 202 to rotate. The rotation of the bevel gear I 202 drives the bevel gear II 204 to rotate. The rotation of the bevel gear II 204 drives the transmission shaft I 203 to rotate. The rotation of the transmission shaft I 203 drives the coupling I 205 to rotate. The rotation of the coupling I 205 drives the cleaning plate 206 to rotate. The rotation of the cleaning plate 206 drives all the bristles 207 to rotate. At the same time, all the driving wheels 2 are controlled to move from right to left along the inner wall of the spiral tube 3 Figure 1 from the perspective of Figure 1 , so that all the bristles 207 are directly inserted into the weld seam on the inner wall of the spiral tube 3, thereby reducing the phenomenon that all the bristles 207 are detached from the weld seam during rotation, and thus improving the cleaning effect of the spiral tube 3.

[0046] And the setting of the notch 2061 enables the impurities cleaned by the bristles 207 to fall from the notch 2061, thereby reducing the accumulation of impurities on the cleaning plate 206. And since the cleaning plate 206 is set in a spiral shape, when the cleaning plate 206 moves and rotates to the left along the spiral tube 3, the cleaning plate 206 can move and rotate along the trajectory of the weld seam, thereby improving the cleaning effect of the weld seam on the inner wall of the spiral tube 3.

[0047] And to further improve the cleaning effect of the spiral tube 3, the rotation of the transmission shaft I 203 drives the support plate I 301 to rotate, and thus the support plate I 301 rotates along the inner wall of the spiral tube 3. At the same time, the rotation of the support plate I 301 drives all the connected components to rotate, and thus the two knocking hammers 307 rotate. Then, the motor 302 is controlled to start. The rotation of the output shaft of the motor 302 drives the ratchet wheel 303 to rotate. The rotation of the ratchet wheel 303 drives the two ratchet teeth 306 to be touched and causes extrusion on the two ratchet teeth 306. Thus, each ratchet tooth 306 drives a corresponding coupling II 305 to rotate. The rotation of the coupling II 305 drives the knocking hammer 307 to rotate and twists the corresponding elastic member I 3071. When the ratchet wheel 303 rotates away from the ratchet tooth 306, the knocking hammer 307 is reset by the elastic force generated by the corresponding elastic member I 3071, and thus the knocking hammer 307 rotates reciprocally to hammer the inner wall of the spiral tube 3, so as to shake off the iron filings on the inner wall of the spiral tube 3. At the same time, it cooperates with all the bristles 207, thereby improving the cleaning effect of the spiral tube 3.

[0048] Example 2. On the basis of Example 1, according to Figure 3 and Figures 7 - 9 as shown, it further includes an auxiliary cleaning system; an auxiliary cleaning system is connected to the support plate I 301; the auxiliary cleaning system includes an electric actuator I 401, a connecting plate 402, a connecting rod 403 and a spiral ring 404; two electric actuators I 401 are fixedly connected to the support plate I 301, and the electric actuator I 401 is an electric push rod; a connecting plate 402 is fixedly connected to the telescopic parts of all the electric actuators I 401; two connecting rods 403 are fixedly connected to the connecting plate 402; a spiral ring 404 is fixedly connected to all the connecting rods 403; the spiral ring 404 is fixedly connected to the cleaning plate 206, and the cleaning plate 206 is made of an elastic material.

[0049] It further includes a support plate II 501, a fixing plate 502, an electric actuator II 503, an elastic member II 504, an elastic plate 505, a transmission shaft II 2031 and a bevel gear III 2041; a transmission shaft II 2031 is rotatably connected to the fixing frame 1, and the double-channel conduit 210 is rotatably connected to the transmission shaft II 2031; a bevel gear III 2041 is fixedly connected to the transmission shaft II 2031; the bevel gear III 2041 meshes with the bevel gear I 202; a support plate II 501 is fixedly connected to the transmission shaft II 2031; two fixing plates 502 are fixedly connected to the support plate II 501; an electric actuator II 503 is fixedly connected to each fixing plate 502, and the electric actuator II 503 is an electric push rod; an elastic member II 504 is fixedly connected to the telescopic part of each electric actuator II 503, and the elastic member II 504 is a spring piece; each elastic member II 504 is slidably connected to a corresponding fixing plate 502; an elastic plate 505 is fixedly connected to one end of each elastic member II 504 away from the telescopic part of the electric actuator II 503; and sandpaper is detachably connected to the elastic plate 505.

[0050] Since all the bristles 207 are cleaning the weld on the inner wall of the spiral tube 3, when the bristles 207 are directly inserted into the weld on the inner wall of the spiral tube 3, the bristles 207 will be deformed to varying degrees when they are directly inserted and blocked by the weld, resulting in incomplete cleaning of the weld by the bristles 207 and reducing the cleaning effect of the spiral tube 3. To solve the above problems, by controlling the two electric actuators I 401 to start, the telescopic parts of the two electric actuators I 401 move together to drive the connecting plate 402 to move, the connecting plate 402 moves to drive all the connecting rods 403 to move, all the connecting rods 403 move to drive the spiral ring 404 to move, and then the cleaning plate 206 is pulled by the movement of the spiral ring 404, so that the cleaning plate 206 is deformed, and then all the bristles 207 are driven to move, so that all the bristles 207 expand and disperse outward, so that more bristles 207 can contact the weld on the inner wall of the spiral tube 3 from different angles, and the bristles 207 can be deformed by the extrusion of the weld, so as to achieve a better cleaning effect.

[0051] Moreover, when the fixing frame 1 and all the driving wheels 2 move into the spiral tube 3, control the start of the two electric actuators II 503. The telescopic parts of the two electric actuators II 503 move to drive an elastic part II 504 to move respectively. The two elastic parts II 504 move to pull a spring plate 505 respectively, so that the elastic parts II 504 and the spring plates 505 are deformed. Then, the outer sides of the two spring plates 505 abut against the inner wall of the spiral tube 3, and the sandpapers on the two spring plates 505 abut against the inner wall of the spiral tube 3. When the bevel gear I 202 rotates, the rotation of the bevel gear I 202 drives the bevel gear II 204 and the bevel gear III 2041 to rotate synchronously, and the rotation directions of the bevel gear II 204 and the bevel gear III 2041 are opposite. Then, the rotation of the bevel gear III 2041 drives the transmission shaft II 2031 to rotate, the rotation of the transmission shaft II 2031 drives the support plate II 501 to rotate, the rotation of the support plate II 501 drives all the fixing plates 502 to rotate, and then drives all the connected components to rotate, and then drives the two spring plates 505 to rotate, so as to polish the inner wall of the spiral tube 3 through the polishing sandpapers on the two spring plates 505, thereby further improving the cleaning effect on the spiral tube 3.

[0052] Then, when all the spring plates 505 move to the leftmost end of the spiral tube 3, it indicates that the impurity removal operation on the spiral tube 3 has been completed. At this time, control all the driving wheels 2 to start moving from left to right along the inner wall of the spiral tube 3, so as to drive all the connected components to move. At the same time, control the closing of the external air supply pipeline, and then control the start of the external water pump for water supply to transport water into the double-channel conduit 210, so that the water flows into the water supply channel in the double-channel conduit 210, and the water flows into the water tank 208 through the multiple water outlet holes 2102 on the double-channel conduit 210, and then sprays the water onto the inner wall of the spiral tube 3 through the four nozzles 2081 on the water tank 208, so as to wash the inner wall of the spiral tube 3 through the water flow. And because all the nozzles 2081 are inclined towards the inner wall of the spiral tube 3, the water sprayed out from all the nozzles 2081 can form a vortex on the inner wall of the spiral tube 3, thereby improving the flushing effect on the inner wall of the spiral tube 3 until all the nozzles 2081 move out of the right end of the spiral tube 3, and then control the external water pump for water supply to stop operating, thus completing the cleaning operation on the spiral tube 3.
