[0045] like Figure 1 A cleaning device for a detachable pipe includes a cleaning tank 1, a clamping mechanism 2, an outer wall spray head 3, a liquid pipeline 4, a liquid valve 5, a gas pipeline 6, a gas valve 7, a cleaning pipeline 8, an inner wall spray head 9, a collecting bucket 10, a lifting device, an operation panel 13, a collecting tank 14, a drain pipe 15, a discharge pipe 16, a water outlet valve 17 and a discharge valve 18.

[0046] A drain port 101 is provided at the bottom of the cleaning tank 1 , and a valve is provided at the drain port 101 .

[0047] Every two clamping mechanisms 2 form a group, which are arranged on the inner wall of the cleaning tank 1 to hold the pipeline. Multiple groups of clamping mechanisms 2 can be arranged as needed, such as 2 groups, 3 groups, etc.

[0048] The clamping mechanism 2 comprises an electric push rod 21 and an arc-shaped clamping block 22, wherein the arc-shaped clamping block is fixedly connected to the end of the electric push rod. The electric push rod 21 can move telescopically to drive the arc-shaped clamping block 22 to move.

[0049] A plurality of outer wall spray heads 3 are arranged on the inner wall of the cleaning tank 1 for cleaning the outer wall of the pipeline. The outer wall spray heads 3 are connected to a water pipe, and when the water pipe is turned on, tap water is sprayed out from the outer wall spray heads 3.

[0050] The liquid pipeline 4 is used to transport cleaning liquid. The gas pipeline 6 is used to transport compressed gas. The liquid valve 5 is arranged on the liquid pipeline 4. The gas valve 7 is arranged on the gas pipeline 6. The liquid pipeline 4 and the gas pipeline 6 can be hoses.

[0051] The first end of the cleaning pipeline 8 is connected to the liquid pipeline 4 and the gas pipeline 6 through a three-way conversion joint. The second end of the cleaning pipeline 8 is provided with an inner wall nozzle 9. The cleaning pipeline 8 is a pipeline made of metal material.

[0052] The collecting tank 14 is arranged on the bottom wall of the cleaning tank 1 and is located in the middle of the bottom wall, and can collect the foaming agent in the pipeline to be cleaned or collect the cleaning liquid of the cleaning pipeline. The bottom of the collecting tank 14 has a liquid outlet. In one embodiment of the utility model, the depth of the collecting tank 14 can be 50 cm-110 cm.

[0053] The drain pipe 15 and the discharge pipe 16 are connected to the liquid outlet of the collection tank 14 using a three-way conversion joint.

[0054] The drain pipe 15 is provided with a water outlet valve 17, and the discharge pipe 16 is provided with a discharge valve 18. The collecting barrel 10 is connected to the discharge pipe 16 and is used to collect the material blown down from the inner wall of the pipe by the high-pressure gas sprayed from the inner wall nozzle 9. The collecting barrel 10 is provided with an emptying port for discharging the high-pressure gas.

[0055] The lifting device includes a lifting motor 11 and a lifting rod 12. The lifting motor 11 can drive the lifting rod 12 to rise and fall. The lifting rod 12 is retractable or can move up and down under the action of the lifting motor 11.

[0056] One end of the fixed cross bar 19 is connected to the cleaning pipeline 8, and the other end is connected to the lifting rod 12. When the lifting rod 12 rises or falls, the inner wall spray head 9 can be driven to rise or fall.

[0057] The control panel 13 communicates with the electric push rod 21, the liquid valve 5, the gas valve 7, the lifting motor 11 of the lifting device, the water outlet valve 17, and the material outlet valve 18 to control their operations.

[0058] Optionally, the sensing device 20 is arranged at the center of the bottom of the collecting tank 14 and is also located on the central axis of the cleaning tank 1. The sensing device 20 is used to sense the position of the inner wall nozzle 9, so that the position of the inner wall nozzle 9 is located on the central axis of the cleaning tank 1, which can better clean the inner wall of the pipeline. The sensing device 20 is connected to the control panel 13 by signal. When the sensing device 20 senses that the inner wall nozzle 9 is not in a straight line with it, a signal is sent to the control panel 13, and the control panel 13 controls the liquid valve 5 and the water outlet valve 17 or the gas valve 7 and the discharge valve 18 to close, and the lifting motor 11 stops running.

[0059] like Figure 2 As shown, the inner wall spray head includes a spray head body 201 , a joint 202 , a nozzle 203 , a fixing rod 204 , and a spray plate 205 .

[0060] The joint 202 and the nozzle 203 are respectively located at the two ends of the nozzle body 201. A sealing ring is arranged inside the joint 202, and a buckle is arranged outside. When the joint 202 is connected to the cleaning pipeline, the buckle is used to fix it. The nozzle 203 can be replaced as needed.

[0061] The fixing rod 204 is fixedly connected to the joint 202 and extends from the nozzle 203 .

[0062] The spray plate 205 is fixedly connected to the end of the fixed rod 204, and the spray plate 205 does not contact the nozzle 203. The surface of the spray plate 205 facing the nozzle 203 is an arc surface, and the gas and liquid sprayed from the nozzle 203 will hit the spray plate, and the spray plate will change the direction, and the cleaning liquid or gas will be sprayed obliquely toward the pipe wall, thereby increasing the cleaning ability.

[0063] When using the above-mentioned cleaning device to clean the pipeline, a transportation tool is used to place the pipeline to be cleaned into the cleaning tank 1, and the electric push rod 21 is started through the control panel 13 so that the arc-shaped clamping block 22 clamps the pipeline from both sides. At this time, the pipeline to be cleaned is located in the collecting tank 14 and does not contact the bottom of the collecting tank 14.

[0064] The lifting motor 11 is controlled by the control panel 13 to lower the inner wall nozzle 9 to the set initial position in the pipeline to be cleaned. The gas valve 7 and the discharge valve 18 are opened by the control panel 13, and the compressed gas is ejected from the inner wall nozzle 9 to the inner wall of the pipeline, which can flush the foaming agent attached to the inner wall of the pipeline and fall into the collection tank 14, and then enter the collection barrel 10 through the discharge pipe 16. When using compressed gas to remove the foaming agent attached to the inner wall of the pipeline, the control panel 13 controls the lifting device to drive the inner wall nozzle 9 to move downward according to the set speed, so as to blow off the foaming agent on the inner wall of the pipeline. The inner wall nozzle 9 stops after descending to the set position, and the control panel 13 closes the gas valve 7 and the discharge valve 18.

[0065] The control panel 13 controls the lifting device to raise the inner wall nozzle to the initial position, and the control panel 13 controls the liquid valve 5 and the water outlet valve 17 to open, and the high-pressure cleaning liquid is sprayed from the inner wall nozzle 9 to clean the inner wall of the pipeline. The control panel 13 controls the lifting device to drive the inner wall nozzle 9 to move downward according to the set speed to clean the inner wall of the pipeline. The inner wall nozzle 9 stops after descending to the set position, and then the control panel 13 closes the liquid valve 5 and the water outlet valve 17. During cleaning, the waste liquid is discharged from the drain pipe 15.

[0066] While the inner wall spray head 9 is used to spray the cleaning liquid to clean the inner wall of the pipe, the tap water pipe is turned on and the outer wall spray head 3 is used to clean the outer wall of the pipe. During the cleaning process, the waste water is discharged from the drain port 101 of the cleaning tank 1. During the cleaning process, some water may fall into the collection tank 14 and will be discharged from the drain pipe 15.

[0067] During the cleaning process, the foaming agent is first blown off the inner wall of the pipe and collected in a collection bucket. The waste liquid is then treated uniformly and water is used to clean the inner wall of the pipe. This can reduce wastewater discharge pollution. Compared with direct water cleaning, the foam is reduced, and the water consumption and waste liquid discharge are reduced.

[0068] Under normal circumstances, the inner wall nozzle 9 and the sensing device 20 are located in the same straight line. If the two are not in the same straight line, the nozzle is offset, and the sensing device 20 sends a signal to the control panel 13. The control panel 13 controls the liquid valve 5 and the water outlet valve 17 or the gas valve 7 and the discharge valve 18 to close, and controls the lifting motor to close. Check whether the connection between the cleaning pipeline 8 and the fixed cross bar 19, and between the lifting rod 12 and the fixed cross bar 19 is loose. It is also necessary to check whether the connection between the lifting rod 12 and the lifting motor 11 is faulty. After finding the problem, repair it and correct the position of the inner wall nozzle 9.

[0069] The provision of the sensing device 20 can prevent the inner wall nozzle from contacting the inner wall of the pipe and affecting the cleaning of the pipe, and also avoid potential safety hazards.

[0070] Although some embodiments of the present invention have been described in this application document, it will be understood by those skilled in the art that these embodiments are only shown as examples. Under the guidance of the present invention, those skilled in the art can think of numerous variations, alternatives and improvements without exceeding the scope of the present invention. The attached claims are intended to define the scope of the present invention and thereby cover methods and structures within the scope of these claims themselves and their equivalents.
