[0032] The present invention proposes a composite pipeline cleaning vehicle. The composite pipeline cleaning vehicle can realize free switching of three cleaning modes of single-phase cleaning, two-phase cleaning and three-phase cleaning to adapt to different pipeline conditions and upstream water source conditions. The construction is simple, no ground excavation is required, and the pipeline is not damaged. The pipeline cleaning operation is simple, convenient and fast. By selecting a suitable cleaning mode according to the pipeline assessment situation and the upstream water source situation, the pipeline safety is effectively protected and pipeline damage is avoided. The water consumption is small, the applicability is wide, the functions are rich, the universality is good, it is easy to promote, the cleaning ability is strong, the cleaning effect is excellent, and compared with pipeline cleaning using chemical agents, there is no problem of agent loss and endangering the safety of water supply quality, there is no need to purchase a large amount of agents, and the cost is low.

[0033] Specifically, in one embodiment of the invention, Figure 1 and Figure 2 As shown, the composite pipeline cleaning vehicle includes a vehicle body and a generator cabinet 3, an electric control cabinet 43, an air compressor 7, a gas tank 8, an electric control valve 41, a central control cabinet 42, an ice maker 6, and an ice storage tank 5 arranged on the vehicle body. A generator 31 is arranged in the generator cabinet 3, and the generator 31 is used to generate electricity for the composite pipeline cleaning vehicle to work, so that the composite pipeline cleaning vehicle of this embodiment can perform pipeline cleaning and driving without connecting to the mains, which improves the practicality of the composite pipeline cleaning vehicle of this embodiment. Of course, the composite pipeline cleaning vehicle of this embodiment also has the function of connecting to the mains for pipeline cleaning. The electric control cabinet 43 is used to control the generator 31 to generate electricity, and distribute the electric energy to the air compressor 7, the gas tank 8, the electric control valve 41, the central control cabinet 42, the ice maker 6, the ice storage tank 5 and other electrical equipment as needed to ensure the normal operation of the above-mentioned electrical equipment. Of course, when the composite pipeline cleaning vehicle of this embodiment is powered by the mains, the electric control cabinet 43 also controls the power distribution of each electrical equipment.

[0034] In this embodiment, if Figure 1 and Figure 2As shown, the generator cabinet 3 is provided with a heat dissipation window 32 and a smoke exhaust hole 33 , wherein the heat dissipation window 32 is used for heat dissipation of the generator 31 , and the smoke exhaust hole 33 is used for smoke exhaust of the generator 31 .

[0035] In this embodiment, if Figure 1 and Figure 2 As shown, the vehicle body includes a vehicle body 1 and a front end 2 arranged at the front end of the vehicle body 1 , and wheels 11 are arranged on the vehicle body 1 and the front end 2 , and the generator cabinet 3 , the box body 4 , and the ice storage tank 5 are all located on the vehicle body 1 .

[0036] In this embodiment, if Figure 1 and Figure 2 As shown, a box body 4 is provided on the vehicle body 1, and the electric control cabinet 43, the air compressor 7, the gas storage tank 8, the electric control valve 41, the central control cabinet 42, and the ice maker 6 are located in the box body 4. The box body 4 has a box door 44. The electric control cabinet 43, the air compressor 7, the gas storage tank 8, the electric control valve 41, the central control cabinet 42, the ice maker 6 and other equipment can be inspected and repaired by opening the box door 44.

[0037] In this embodiment, if Figure 1 and Figure 2 As shown, the air outlet end of the air compressor 7 is connected to an air injection pipe 81, and the air storage tank 8 and the electric control valve 41 are arranged in sequence on the air injection pipe 81 along the gas flow direction. With this design, after the air compressor 7 is started, high-pressure gas is stored in the air storage tank 8. When it is necessary to inject high-pressure gas pulses into the pipeline, the electric control valve 41 is controlled to open for a very short period of time so that the high-pressure gas in the air storage tank 8 can be injected into the pipeline through the air injection pipe 81. The gas pulse frequency can be adjusted by adjusting the opening and closing time of the electric control valve 41, so that it is suitable for cleaning various pipelines.

[0038] In this embodiment, if Figure 1 and Figure 2 As shown, the ice maker 6 and the ice storage tank 5 are connected through a liquid inlet pipe 61 and a liquid outlet pipe 62. After the ice maker 6 is started, the antifreeze in the ice maker 6 enters the ice storage tank 5 through the liquid inlet pipe 61 to perform heat exchange with the water in the ice storage tank 5, so that the temperature of the water decreases until the concentration of ice slurry in the water in the ice storage tank 5 reaches 40%-55%. Specifically, it can be judged whether the ice maker 6 needs to end its work by opening the drain pipe 53 and observing the concentration of ice slurry in the water discharged from the ice storage tank 5. After the antifreeze completes the heat exchange with the water, it returns to the ice maker 6 through the liquid outlet pipe 62. The ice storage tank 5 is made of stainless steel and has both heat preservation and anti-corrosion properties.

[0039] In this embodiment, if Figure 1 and Figure 2As shown, a screw pump 51 is provided at the bottom of the ice storage tank 5, and the outlet end of the screw pump 51 is connected to the slurry outlet pipe 54. After the screw pump 51 is started, the ice slurry in the ice storage tank 5 is extracted and injected into the slurry outlet pipe 54 for discharge. Therefore, one end of the pipe mouth of the pipeline to be cleaned should be connected to and fixed with the slurry outlet pipe 54, and the slurry outlet pipe 54 is connected to the air injection pipe 81. With this design, high-pressure gas can be injected into the pipeline to be cleaned through the air injection pipe 81, and a check valve should be provided on the corresponding slurry outlet pipe 54 to prevent the high-pressure gas from flowing back into the screw pump 51 and affecting the pipeline cleaning work.

[0040] In this embodiment, if Figure 1 and Figure 2 As shown, the ice storage tank 5 is provided with a water inlet pipe 52 and a sewage pipe 53 . The water inlet pipe 52 is used to inject room temperature water into the ice storage tank 5 , and the sewage pipe 53 is used to drain excess water in the ice storage tank 5 .

[0041] In this embodiment, if Figure 1 and Figure 2 As shown, the ice storage tank 5 is provided with a stirring device 9, the stirring device 9 comprises a stirring motor 91 and a stirring shaft drivingly connected to the stirring motor 91, the stirring shaft is provided with a streamlined blade 92, the stirring shaft is located in the ice storage tank 5, and the stirring shaft is horizontally arranged, and the angle between the streamlined blade 92 and the plane perpendicular to the central axis of the stirring shaft is 30°-45°. In this design, Figure 1 The stirring motor 91 drives the stirring shaft to rotate, so that the streamlined blade 92 can generate a leftward thrust on the ice slurry. Figure 1 The ice slurry on the right side of the middle ice storage tank 5 is pushed into the left side, forming a hydraulic vortex that circulates and flips left and right, ensuring that the ice slurry and water are evenly mixed.

[0042] In this embodiment, if Figure 1 and Figure 2 As shown, the ice storage tank 5 is provided with an inspection port 55 and a ladder 56. The inspection port 55 is located at the top of the ice storage tank 5. The inspection port 55 is convenient for internal inspection of the ice storage tank 5. The existence of the ladder 56 is convenient for people to climb to the top inspection port 55 of the ice storage tank 5. A guardrail 57 is provided around the ice storage tank 5 to protect the ice storage tank 5 and the screw pump 51, slurry discharge pipe 54, water inlet pipe 52, sewage pipe 53, and stirring device 9 arranged thereon. The guardrail 57 is fixedly connected to the vehicle body.

[0043] In this embodiment, the central control cabinet 42 is used to control the composite pipeline cleaning vehicle to perform pipeline cleaning operations, specifically including controlling the air compressor 7, the electric control valve 41, the ice maker 6, the screw pump 51, and the stirring motor 91 to cooperate with each other to complete the pipeline cleaning work. The central control cabinet 42 includes a central processor PLC, a data acquisition analog input module, a touch display screen and a server. The data acquisition analog input module includes a flow meter, a pressure sensor, and a temperature sensor. The flow meter, pressure sensor, and temperature sensor are installed on the pipeline to be flushed to detect the flow, pressure and temperature in the pipeline. Pressure sensors and temperature sensors are provided at both ends of the pipeline to detect the temperature difference and pressure difference at both ends of the pipeline, so as to provide a reference for adjusting the injection time of gas into the pipeline, the gas stop time of pausing the injection of gas into the pipeline, the air pressure of the gas injected into the pipeline, and the operating frequency of the screw pump 51.

[0044] When it is necessary to clean the pipeline, first connect one end of the pipeline to the slurry outlet pipe 54 and fix it, and then select an appropriate cleaning mode according to the actual evaluation of the pipeline and the upstream water source. For example, when the inner wall of the pipeline to be cleaned contains a light microbial film or there is a large leak on the pipeline or the pipeline to be cleaned is a plastic pipe, and the upstream water source is sufficient, a large amount of upstream water can be injected into the ice storage tank 5. At this time, single-phase cleaning is adopted. The single-phase cleaning is to control the screw pump 51 to inject the water in the ice storage tank 5 into the pipeline through the slurry outlet pipe 54, and use high-pressure and high-speed water flow to flush the inner wall of the pipeline. The specific water pressure and water speed can be flexibly controlled according to the actual situation of the pipeline, as long as the pipeline is not damaged;

[0045] When the pipe to be cleaned is severely corroded and has no major leaks or the pipe to be cleaned is a non-plastic pipe, three-phase cleaning or two-phase cleaning can be used. The three-phase cleaning is to control the screw pump 51 to start for a period of time to inject the ice slurry in the ice storage tank 5 into the pipe through the slurry outlet pipe 54, then control the screw pump 51 to pause, and then control the electric control valve 41 to inject high-pressure gas into the pipe. After a period of time, the gas injection is paused, and the ice slurry is continuously injected into the pipe. Then the ice slurry is paused, and high-pressure gas is injected into the pipe again. After a period of time, the gas injection is paused, and the ice slurry is continuously injected into the pipe. This alternating cycle causes a section of ice column and a section of high-pressure gas to appear in the pipe. Each time a section of high-pressure gas is injected into the pipe, the ice column is pushed forward in the pipe. The high-pressure pulse gas is used to push the ice column in the pipe. The internal flow and the friction between the inner wall of the pipe remove the biofilm, sediment, rust and other dirt on the inner wall of the pipe. The pulse gas and ice slurry are alternately injected into the pipe, so that the inner wall of the pipe is rubbed by multiple sections of ice columns for multiple times, and the biofilm, sediment, rust and other dirt on the inner wall of the pipe are effectively wiped off. The pipe cleaning ability is strong and the cleaning effect is excellent. In addition, the high-pressure pulse gas can generate shock waves in the pipe, which impact the dirt and sediment in the pipe, so that the biofilm, sediment, rust and other dirt on the inner wall of the pipe are loosened and fall off, which is conducive to the icicles to easily rub off the biofilm, sediment, rust and other dirt on the inner wall of the pipe, and further improve the cleaning effect, ensuring that the stubborn dirt adsorbed on the inner wall of the pipe is removed, and the water consumption is small, which saves a lot of water resources compared with traditional hydraulic cleaning and high-pressure cleaning methods.

[0046] In this embodiment, in order to obtain excellent pipeline cleaning effect, the length of the icicle cannot be too short, but the longer the length of the icicle, the more difficult it is to push it forward in the pipeline, and the greater the friction resistance of the icicle forward. However, due to the limitations of the pipeline's own performance and the cost of preparing high-pressure gas, the pressure of the high-pressure pulse gas cannot be increased indefinitely. Therefore, in this embodiment, a very long icicle is replaced with multiple sections of shorter icicles, and pulse gas and ice slurry are alternately injected into the pipeline to achieve multiple frictions of the inner wall of the pipeline by multiple sections of icicles, effectively wiping off biofilms, sediments, rust and other contaminants on the inner wall of the pipeline. Moreover, a large air pressure is not required to push the shorter icicle forward in the pipeline, which is conducive to reducing the cost of pipeline flushing. Of course, the length of the icicle cannot be too short, otherwise it is easy to be shattered under the impact of the pulse gas.

[0047] In this embodiment, the time for injecting gas into the pipeline cannot be too short, otherwise there is a risk that two adjacent sections of icicles in the pipeline will come into contact with each other to form a long icicle. The time for injecting gas and ice slurry into the pipeline is achieved by the central control cabinet 42 controlling the action duration of the electric control valve 41 and the screw pump 51.

[0048] In this embodiment, the two-phase cleaning is to alternately inject the water in the ice storage tank 5 and the high-pressure gas in the gas storage tank 8 into the pipeline, so that a section of water column and a section of high-pressure gas appear in the pipeline. This cleaning method is suitable for the situation where the upstream water source is sufficient, and a large amount of upstream water source can be injected into the ice storage tank 5. On the contrary, when the upstream water source is not enough to support a large amount of water use in the ice storage tank 5, three-phase cleaning can be used to consume less water resources to achieve excellent cleaning effect. Whether to use two-phase cleaning or three-phase cleaning can be flexibly controlled according to the actual situation of the pipeline and the upstream water source.

[0049] It can be seen that the composite pipeline cleaning vehicle of this embodiment can flexibly select a suitable cleaning method according to the conditions of the pipeline and the upstream water source. The construction is simple and there is no need to excavate the ground. It only needs to connect and fix a section of the pipeline to the slurry outlet pipe 54 without damaging the pipeline. The pipeline cleaning operation is simple, convenient and fast.

[0050] The composite pipeline cleaning vehicle of this embodiment effectively protects the safety of the pipeline and avoids damage to the pipeline by improper pipeline cleaning methods by selecting an appropriate cleaning mode according to the pipeline assessment situation and the upstream water source situation. Compared with conventional cleaning methods, it has low water consumption, wide applicability, rich functions, good universality, easy promotion, strong cleaning ability, and excellent cleaning effect. Moreover, compared with pipeline cleaning using chemical agents, there is no problem of agent loss and endangerment to water supply quality safety, and there is no need to purchase a large amount of agents, so the cost is low.

[0051] In addition, the composite pipeline cleaning vehicle of this embodiment is not only suitable for water supply pipelines, but also can be used for drainage or oil pipeline cleaning.
