[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 and easy processing.

[0025] The fixing frame 1 is provided with a visual sensor for detecting the inner side of the spiral tube 3 .

[0026] The cleaning plate 206 is configured to be spirally shaped so as to better clean the weld seam inside the spiral tube 3 .

[0027] A plurality of notches 2061 are formed on the cleaning plate 206 , and each group of bristles 207 is disposed at the edge of a corresponding notch 2061 , so as to quickly discharge the cleaned impurities in the spiral tube 3 .

[0028] All the bristles 207 are made of metal to increase the service life of the bristles 207 .

[0029] 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.

[0030] 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 driving assembly is connected to the support plate Ⅰ301; a pulley is installed at the upper end and the lower end of the support plate Ⅰ301; 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 frame There is a connecting shaft II 305 rotatably connected to 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.

[0031] 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 .

[0032] 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.

[0033] 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.

[0034] 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.

[0035] In order to solve the above problem, the gas pipeline of the external device is controlled to be opened, so that the gas enters the gas transmission channel in the dual-channel conduit 210, and the gas is transmitted to the flamethrower 209 through the gas transmission hole 2103, and the flamethrower 209 is operated and ignited, so that the flamethrower 209 sprays the fire to the inner wall of the spiral tube 3, so that the inner wall of the spiral tube 3 is preheated by the flame sprayed by the flamethrower 209, so that the rust layer and oil stains on the inner wall of the spiral tube 3 are more easily removed, thereby reducing the damage to the spiral tube 3. The cleaning difficulty is then increased, and the motor 201 is controlled to start, the output shaft of the motor 201 rotates to drive the bevel gear I 202 to rotate, the bevel gear I 202 rotates to drive the bevel gear II 204 to rotate, the bevel gear II 204 rotates to drive the transmission shaft I 203 to rotate, the transmission shaft I 203 rotates to drive the connecting shaft I 205 to rotate, the connecting shaft I 205 rotates to drive the cleaning plate 206 to rotate, the cleaning plate 206 rotates to drive all the bristles 207 to rotate, and at the same time all the driving wheels 2 are controlled to start to rotate along the inner wall of the spiral tube 3 to Figure 1 Taking the viewing angle as an example, moving from right to left, all the bristles 207 are directly inserted into the weld of the inner wall of the spiral tube 3, thereby reducing the phenomenon that all the bristles 207 are separated from the weld during the rotation process, thereby improving the cleaning effect of the spiral tube 3.

[0036] In addition, by setting the notch 2061, the impurities cleaned by the bristles 207 can fall from the notch 2061, thereby reducing the accumulation of impurities on the cleaning plate 206. And because the cleaning plate 206 is set in a spiral shape, when the cleaning plate 206 moves to the left and rotates along the spiral tube 3, the cleaning plate 206 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 tube 3.

[0037] In order to further improve the cleaning effect of the spiral tube 3, the transmission shaft Ⅰ203 rotates to drive the support plate Ⅰ301 to rotate, so that the support plate Ⅰ301 rotates along the inner wall of the spiral tube 3. At the same time, the support plate Ⅰ301 rotates to drive all the connected parts to rotate, so that the two knock hammers 307 rotate, and then the motor 302 is controlled to start, and the output shaft of the motor 302 rotates to drive the ratchet 303 to rotate. The rotation of the ratchet 303 drives it to touch the two ratchet teeth 306 and squeeze the two ratchet teeth 306, so that Each ratchet tooth 306 drives a corresponding connecting shaft II 305 to rotate, and the rotation of the connecting shaft II 305 drives the knocking hammer 307 to rotate and twist the corresponding elastic member I 3071. When the ratchet wheel 303 rotates and disengages from the ratchet tooth 306, the knocking hammer 307 is reset by the elastic force generated by the corresponding elastic member I 3071, so that the knocking hammer 307 reciprocates and hammers the inner wall of the spiral tube 3, thereby shaking off the iron filings on the inner wall of the spiral tube 3, and at the same time cooperates with all the bristles 207 to improve the cleaning effect of the spiral tube 3.

[0038] Embodiment 2:

[0039] Based on the first embodiment, Figure 3 and Figure 7-Figure 9 As shown, an auxiliary cleaning system is also included; the auxiliary cleaning system is connected to the support plate Ⅰ301; the auxiliary cleaning system includes an electric actuator Ⅰ401, a connecting plate 402, a connecting rod 403 and a spiral ring 404; two electric actuators Ⅰ401 are fixedly connected to the support plate Ⅰ301, and the electric actuators Ⅰ401 are electric push rods; the telescopic parts of all electric actuators Ⅰ401 are commonly fixedly connected to a connecting plate 402; two connecting rods 403 are fixedly connected to the connecting plate 402; a spiral ring 404 is commonly fixedly connected to all connecting rods 403; the spiral ring 404 is fixedly connected to the cleaning plate 206, and the cleaning plate 206 is made of elastic material.

[0040] It also includes a support plate II 501, a fixed 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; the fixed frame 1 is rotatably connected to the transmission shaft II 2031, and the dual-channel conduit 210 is rotatably connected to the transmission shaft II 2031; the transmission shaft II 2031 is fixedly connected to the bevel gear III 2041; the bevel gear III 2041 is meshed with the bevel gear I 202; the transmission shaft II 2031 is fixedly connected to the support plate II 501; the support plate II 501 is fixedly connected to the bevel gear There are two fixed plates 502; each fixed plate 502 is fixedly connected to an electric actuator II 503, which is an electric push rod; the telescopic part of each electric actuator II 503 is fixedly connected to an elastic member II 504, which is a spring; each elastic member II 504 is slidably connected to a corresponding fixed plate 502; one end of each elastic member II 504 away from the telescopic part of the electric actuator II 503 is fixedly connected to an elastic plate 505; and sandpaper is detachably connected to the elastic plate 505.

[0041] When 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 blocked by the weld and will be deformed to varying degrees, which will result in incomplete cleaning of the weld by the bristles 207, thereby reducing the cleaning effect of the spiral tube 3. To solve the above problem, by controlling the two electric actuators Ⅰ401 to start, the telescopic parts of the two electric actuators Ⅰ401 move to jointly drive the connecting plate 402 to move, the movement of the connecting plate 402 drives all the connecting rods 403 to move, and the movement of all the connecting rods 403 drives 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, thereby driving all the bristles 207 to move, and then all the bristles 207 are expanded and spread 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 squeezed by the weld and deformed, thereby achieving a better cleaning effect.

[0042] Furthermore, when the fixing frame 1 and all the driving wheels 2 move into the spiral tube 3, the two electric actuators Ⅱ503 are controlled to start, and the telescopic parts of the two electric actuators Ⅱ503 move, each driving an elastic member Ⅱ504 to move, and the two elastic members Ⅱ504 move, each pulling an elastic plate 505, so that the elastic member Ⅱ504 and the elastic plate 505 are deformed, so that the outer sides of the two elastic plates 505 are pressed against the inner wall of the spiral tube 3, and the sandpaper on the two elastic plates 505 is pressed against the inner wall of the spiral tube 3. When the bevel gear Ⅰ202 rotates, the rotation of the bevel gear Ⅰ202 drives Bevel gear II 204 and bevel gear III 2041 rotate synchronously, and bevel gear II 204 and bevel gear III 2041 rotate in opposite directions, so that the rotation of bevel gear III 2041 drives the transmission shaft II 2031 to rotate, and the rotation of transmission shaft II 2031 drives the support plate II 501 to rotate, and the rotation of support plate II 501 drives all fixed plates 502 to rotate, and then drives all connected parts to rotate, and then drives the two elastic plates 505 to rotate, so that the inner wall of the spiral tube 3 is polished by the grinding sandpaper on the two elastic plates 505, thereby further improving the cleaning effect of the spiral tube 3.

[0043] Then, when all the elastic plates 505 move to the leftmost end of the spiral tube 3, it means that the impurity removal operation of the spiral tube 3 has been completed. At this time, all the driving wheels 2 are controlled to start moving along the inner wall of the spiral tube 3 from left to right, thereby driving all the connected parts to move. At the same time, the air pipeline of the external device is controlled to be closed, and the external pump for water delivery is controlled to start operating to deliver water to the dual-channel conduit 210, so that the water flows into the water delivery channel in the dual-channel conduit 210, and flows into the water tank 208 through the multiple water outlet holes 2102 on the dual-channel conduit 210. Water is then sprayed toward the inner wall of the spiral tube 3 through the four nozzles 2081 on the water tank 208, so that the inner wall of the spiral tube 3 is flushed by the water flow, and since all the nozzles 2081 are inclined toward the inner wall of the spiral tube 3, the water sprayed through all the nozzles 2081 can form a vortex on the inner wall of the spiral tube 3, thereby enhancing the flushing effect on the inner wall of the spiral tube 3, until all the nozzles 2081 are moved out from the right end of the spiral tube 3, and then the external pump used for water delivery is controlled to stop operating, thereby completing the cleaning operation of the spiral tube 3.
