[0024] like Figures 1-4 As shown, a heating pipeline internal cleaning robot includes a pipeline cleaning pump 1, a support frame 2, and a protective cylinder 3. The inner wall of the protective cylinder 3 is provided with a cleaning adjustment component 4.

[0025] The cleaning adjustment assembly 4 includes a fixing ring 401 set on the inner wall of the protective cylinder 3. The inner wall of the fixing ring 401 is connected to a support arm 402 by fastening bolts. The outer wall of the support arm 402 is connected to a power source 403 by a fixing bracket threadedly. The ends of the multiple power sources 403 away from the fixing ring 401 are connected to telescopic shafts 404. The outer wall of the telescopic shafts 404 is connected to a limit spring 406. The ends of the multiple telescopic shafts 404 away from the power source 403 are connected to a limit seat 405. The outer wall of the limit seat 405 is connected to a positioning frame 407 by a connecting rod. The end of the positioning frame 407 away from the limit seat 405 is connected to a cleaning frame 409. The inner wall of the cleaning frame 409 is connected to multiple movable shafts 410. The outer wall of the cleaning frame 409 is connected to a cleaning conveyor belt 411. The limit seat 405 is connected to a limit frame 408 by fastening bolts.

[0026] The support arm 402 is connected to the inner wall of the fixing ring 401 by fastening bolts. The power source 403 is connected to the fixing frame at the end of the outer wall of the support arm 402 near the fixing ring 401 by fastening bolts. The power source 403 is connected to the telescopic shaft 404. The limiting spring 406 is sleeved on the outer wall of the telescopic shaft 404. The end of the telescopic shaft 404 away from the power source 403 is threadedly fixed to the limiting seat 405. The bottom of the limiting seat 405 is slidably connected in the groove opened on the outer wall of the support arm 402 by a slider.

[0027] The process involves placing the support frame 2 at the inlet of the heating pipe to be cleaned, ensuring its stability, fitting the protective sleeve 3 onto the support frame 2 and securing it to form the main frame of the robot, fixing the fixing ring 401 to one end of the support arm 402 with fastening bolts, fixing the power source 403 to the fixing frame on the outer wall of the support arm 402 with fastening bolts, connecting the telescopic shaft 404 to the power source 403 and ensuring its smooth extension and retraction, fitting the limit spring 406 onto the outer wall of the telescopic shaft 404, and fitting the limit seat 4... 05 Connect the end of the telescopic shaft 404 away from the power source 403 via a thread, connect the positioning frame 407 to the limit seat 405 via fastening bolts, connect the limit frame 408 to the positioning frame 407 via a thread, connect the cleaning frame 409 to the limit frame 408 via a thread, install the movable shaft 410 on the inner wall of the cleaning frame 409 and ensure that it can rotate freely, install the cleaning conveyor belt 411 on the cleaning frame 409 via the movable shaft 410 and ensure that it can rotate around the movable shaft 410;

[0028] The power source 403 is started, driving the telescopic shaft 404 to move the limiting seat 405 in the groove on the outer wall of the support arm 402, thereby adjusting the position of the cleaning frame 409 and the cleaning conveyor belt 411. The position of the cleaning conveyor belt 411 is adjusted by controlling the extension and retraction of the power source 403 to align it with the area to be cleaned. The moving shaft 410 limits the cleaning conveyor belt 411 to ensure that it does not shift during the cleaning process.

[0029] A cleaning installation assembly 5 is provided at the end of the support arm 402 away from the protective cylinder 3. The cleaning installation assembly 5 includes a fixed seat 501 at one end of the support arm 402. A conveying pipe 502 is connected to the end of the fixed seat 501 away from the support arm 402. A sealing pipe 504 is connected to the end of the conveying pipe 502 away from the fixed seat 501. A protective sleeve 503 is sleeved on one end of the outer wall of the conveying pipe 502. A regulating valve 509 is connected to the top of the protective sleeve 503. A sealing seat 505 is sleeved on the outer wall of the sealing pipe 504. A sealing disc 506 is connected to the end of the sealing seat 505 away from the fixed seat 501 through a connecting rod. An installation block 507 is connected to the end of the sealing disc 506 away from the sealing seat 505. A water spray nozzle 508 is connected to the end of the installation block 507 away from the sealing disc 506.

[0030] The fixed seat 501 is sleeved on one end of the outer wall of the conveying pipe 502. The conveying pipe 502 is rotatably connected to the sealing pipe 504. The protective sleeve 503 is sleeved on one end of the outer wall of the conveying pipe 502. The protective sleeve 503 is rotatably connected to the regulating valve 509. The end of the sealing pipe 504 away from the conveying pipe 502 is rotatably connected to one end of the sealing disc 506. The sealing seat 505 is threadedly fixed to the sealing disc 506 through the connecting rod. One end of the conveying pipe 502 passes through the support arm 402 and is connected to the pipeline cleaning pump 1.

[0031] The process involves fitting a fixed base 501 onto one end of the outer wall of the delivery pipe 502, connecting the delivery pipe 502 through the support arm 402 to the pipeline cleaning pump 1, rotatably connecting the end of the delivery pipe 502 away from the fixed base 501 to the sealing pipe 504, fitting a protective sleeve 503 onto one end of the outer wall of the delivery pipe 502, ensuring it can rotate freely, mounting a regulating valve 509 on top of the protective sleeve 503 via a rotatable connection, fitting a sealing seat 505 onto the outer wall of the sealing pipe 504, threadedly connecting a sealing disc 506 to the end of the sealing seat 505 away from the fixed base 501 via a connecting rod, and connecting a mounting block 507 to the end of the sealing disc 506 away from the sealing seat 505 via a connecting rod. The water nozzle 508 is installed on the end of the mounting block 507 away from the sealing plate 506. The pipeline cleaning pump 1 is started, and the cleaning water is transported to the heating pipeline through the delivery pipe 502. The regulating valve 509 is used to control the flow rate of the water source transported by the delivery pipe 502 to achieve quantitative regulation. The cleaning water reaches the water nozzle 508 through the sealing pipe 504, the sealing plate 506, and the mounting block 507. The water nozzle 508 sprays water onto the inner wall of the heating pipeline for preliminary rinsing. The cleaning conveyor belt 411 rotates under the drive of the power source 403, driving the brush on it to scrub the inner wall of the heating pipeline to remove dirt and rust. The water flow sprayed from the water nozzle 508, together with the scrubbing of the cleaning conveyor belt 411, improves the cleaning effect.

[0032] It should be noted that this utility model is a cleaning robot for the interior of a heating pipeline. In use, the power source 403 drives the telescopic shaft 404, which can extend and retract under the action of the limiting spring 406. This causes the limiting seat 405 to slide within the groove on the outer wall of the support arm 402. The sliding of the limiting seat 405 causes the positioning frame 407 and the cleaning frame 409 to move, thereby adjusting the position of the cleaning conveyor belt 411. The movable shaft 410 limits the cleaning conveyor belt 411, ensuring its stable operation. The pipeline cleaning pump 1 delivers cleaning water into the heating pipeline through the delivery pipe 502. The delivery pipe 502 and the sealing pipe 504 are rotatably connected to ensure a tight seal. The protective sleeve 503 protects the connection between the delivery pipe 502 and the sealing pipe 504. The regulating valve 509 quantitatively regulates the water supply through the delivery pipe 502 and controls the flow rate of the cleaning water. The sealing pipe 504 is connected to the spray nozzle 508 through the sealing disc 506 and the mounting block 507. The spray nozzle 508 sprays water into the heating pipe and works with the cleaning conveyor belt 411 to clean the inner wall of the pipe. The fixing seat 501 and the sealing seat 505 achieve a sealed connection between the delivery pipe 502 and the sealing pipe 504 to ensure that the water source does not leak during the cleaning process.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
