DETAILED DESCRIPTION

[0053] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0054] First, those skilled in the art should understand that these implementations are only used to explain the technical principles of the present application and are not intended to limit the scope of protection of the present application. Those skilled in the art can make adjustments to them as needed to adapt to specific application scenarios.

This is merely for the convenience of description and does not indicate or imply that the device or component must have a specific orientation, be constructed and operated in a specific orientation. Therefore, it should not be understood as a limitation on the present application.

[0056] In addition, it should be noted that in the description of this application, unless otherwise clearly specified and limited, the terms "connected" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be the internal communication of two components. For those skilled in the art, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0057] In the description of the present application, the description with reference to the terms "one embodiment", "some embodiments", "illustrative embodiments", "examples", "specific examples", or "some examples" means that the specific features, structures, materials, or characteristics described in conjunction with the embodiment or example are included in at least one embodiment or example of the present application. In the present application, the schematic representations of the above terms do not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials, or characteristics described may be combined in any one or more embodiments or examples in a suitable manner.

[0058] During the long-term service of drainage pipes, due to unreasonable use, inadequate maintenance, and the intrusion of silt and debris, bottom siltation will occur, and even some dense scaling will form on the inner wall of the pipe, affecting the normal function of drainage. One of the important reasons for urban waterlogging is the siltation of drainage pipes, which reduces the drainage capacity of drainage pipes. If the pipes are not cleaned and unblocked, sewage will overflow and pollute the environment. Pipe cleaning has become an important task that cannot be ignored.

[0059] The main cleaning method in the prior art is manual cleaning, which is usually carried out by a person carrying a cleaning device into the pipeline to clean the garbage obstacles in the pipeline and the dirt attached to the pipe wall.

[0060] However, manual cleaning is inefficient and has potential safety hazards. Manual operation cannot be performed when the diameter of the drainage pipe is less than 800 mm. In view of the above problems, the embodiment of the present application improves the cleaning mechanism 100 and the driving mechanism 500 of the cleaning device. When the pipeline cleaning device provided by the present application is applied to pipeline cleaning operations, the driving mechanism 500 provides the cleaning mechanism 100 with power to move forward in the pipeline. The power supply provided on the support assembly can drive the cleaning cutter disc 104 to rotate, thereby driving the second scraper 1043 provided on the cutter disc body to rotate and scrape off the dirt in the pipeline. The cleaning surface of the first scraper 1048 of the present application faces the inner wall of the pipeline, and the cleaning surface is in contact with the inner wall of the pipeline. When the cutter disc body rotates, the first scraper 1048 is driven to rotate to clean the dirt attached to the inner wall of the pipeline and complete the cleaning of the inner wall of the pipeline. Compared with manual cleaning of the inner wall of the pipeline, the pipeline cleaning device provided by the present application has high cleaning efficiency, and does not require personnel to enter the interior of the pipeline, thereby avoiding the potential safety hazards caused by personnel entering the pipeline, and is also suitable for cleaning of small-diameter pipelines that are difficult for personnel to enter.

[0061] The pipe cleaning device provided in this embodiment can be applied to pipes of various different diameters, wherein the installation cabin 102, the sewage cabin 103 and the cleaning blade 104 included in the cleaning mechanism 100 can be assembled on-site according to the size of the pipe diameter to be cleaned, and at the same time, one or more posture adjustment mechanisms 200 can also be set to adapt to complex pipe paths, and the sealing plate 301 of the dry ice micro-explosion mechanism 300 can also be assembled according to the size of the inner diameter of the pipe.

[0062] It is worth mentioning that before starting the cleaning work, select the pipe section to be cleaned and inspected. Generally, the pipe section between adjacent inspection wells is used as a cleaning and inspection unit; air bags are installed at the tail end of the upstream pipe section and the head end of the downstream pipe section for temporary blocking; if the water level in the pipe section to be cleaned and inspected is high, take temporary drainage or suction and other measures to lower the water level to facilitate the hoisting and installation of the integrated operating device.

[0063] Figure 1This is a schematic diagram of the structure of the pipeline cleaning device provided in an embodiment of the present application. Figure 2 A schematic structural diagram of the cleaning structure in the pipeline cleaning device provided in an embodiment of the present application.

[0064] like Figure 1 and Figure 2 As shown, the cleaning device provided in the embodiment of the present application may include a cleaning mechanism 100 and a driving mechanism 500, the cleaning mechanism 100 includes a supporting assembly and a cleaning blade 104, the driving mechanism 500 drives the supporting assembly to move, the cleaning blade 104 includes a blade body and a first scraper 1048, the blade body is rotatably arranged on the supporting assembly, the blade body is provided with a plurality of second scrapers 1043 arranged in sequence, a sewage outlet 1042 is formed between two adjacent second scrapers 1043, the first scraper 1048 is arranged around the circumference of the second scraper 1043, the first scraper 1048 is used to contact the inner wall of the pipe and scrape off the dirt adhering to the inner wall of the pipe.

[0065] Among them, the second scraper 1043 is used to clean the dirt in the pipeline that is in the forward direction of the cleaning device, the first scraper 1048 is used to clean the dirt adhered to the pipe wall, and the sewage outlet 1042 is arranged between the second scraper 1043. When the cleaning blade 104 rotates, the real-time position of the sewage outlet 1042 will also change. The debris of the dirt formed after cleaning by the second scraper 1043 flows into the sewage outlet 1042. Since the real-time position of the sewage outlet 1042 changes, debris will enter different sewage outlets 1042, thereby avoiding the situation where a single sewage outlet 1042 is blocked by debris, thereby improving the cleaning efficiency.

[0066] The present application completes the cleaning of the inner wall of the pipeline by driving the first scraper 1048 and the second scraper 1043 to rotate. Compared with manual cleaning of the inner wall of the pipeline, the pipeline cleaning device of the present application has high cleaning efficiency and does not require personnel to enter the interior of the pipeline, thereby avoiding the safety hazards caused by personnel entering the pipeline and is suitable for cleaning small-diameter pipelines that are difficult for personnel to enter.

[0067] First, the specific structural arrangement and transmission connection relationship inside the cleaning blade disc 104 are described in detail below.

[0068] Figure 3 for Figure 2 The left view of Figure 4 for Figure 2 Right view of Figure 5 for Figure 2 Sectional view at AA, Figure 6 for Figure 2 Cross-sectional view at the middle BB, Figure 7 for Figure 2 Sectional view at CC.

[0069] Reference Figures 2 to 7 As shown, in a possible implementation, the cleaning mechanism 100 may include a mounting member 105 , a mounting chamber 102 , and a sewage chamber 103 , wherein the mounting member 105 is partially inserted into the sewage chamber 103 , and the cutter disc body is inserted on the mounting member 105 .

[0070] The sewage tank 103 is arranged between the installation tank 102 and the cutter head body, and the sewage outlet 1042, the sewage tank 103 and the installation tank 102 are connected in sequence.

[0071] The support assembly includes a support member 101 and at least two adjusting members arranged on the support member 101 . The adjusting members rotate relative to the support member 101 to abut against the inner wall of the pipeline. The support member 101 is partially inserted into the installation cabin 102 .

[0072] It can be understood that the sewage tank 103 is arranged on the back of the cleaning blade 104, and the debris formed after cleaning by the cleaning blade 104 is further discharged into the sewage tank 103 through the sewage outlet 1042. The plate at the bottom of the sewage tank 103 is a sewage tank sealing plate 1032. A hole is also opened on the sealing plate for installing a sewage pipe. The sewage pipe leads to the outside of the pipe, and the debris and other sundries collected in the sewage tank 103 are discharged to the outside of the pipe.

[0073] It is worth mentioning that at least one stop ring 1031 is also mounted on the outside of the sewage tank 103. The outer diameter of the stop ring 1031 can be selected and installed according to the inner diameter of the pipe to be cleaned. The purpose is to form a close seal between the stop ring 1031 and the inner wall of the pipe to prevent debris or sewage formed by cleaning from flowing into the rear end of the cleaning device, thereby causing the debris formed after cleaning to remain on the inner wall of the pipe, resulting in poor cleaning effect.

[0074] Those skilled in the art can understand that the support assembly is arranged at the tail of the cleaning mechanism 100, wherein the roller 1013 on the roller support arm 1012 is always in contact with the inner wall of the pipe, providing support force for the cleaning disc 104 and the mud and water chamber 103, etc., to prevent the cleaning mechanism 100 from deviating during movement and causing damage to the cleaning disc 104.

[0075] The present application realizes further discharge of the waste formed after treatment in the pipeline by adding a sewage tank 103 component to avoid blockage in the pipeline. In addition, a stop ring 1031 is sleeved on the outside of the sewage tank 103 to prevent the waste formed by cleaning from further flowing into the rear components and causing impact. A support component is also added to provide support for the cleaning blade 104 to prevent the cleaning mechanism 100 from deviating during displacement and causing damage to the cleaning blade 104.

[0076] Please continue to refer to Figures 2 to 7 In one possible implementation,

[0077] The cleaning mechanism 100 may further include a driving member 1021 and a transmission assembly, wherein the driving member 1021 is disposed on the supporting assembly.

[0078] A shielding member 1044 is sleeved on the mounting member 105, and each second scraping member 1043 is connected to the shielding member. The driving member 1021 is connected to the shielding member 1044 through a transmission assembly, so as to drive the cutter disc body to rotate relative to the mounting member 105 through the transmission assembly, the shielding member 1044 and the second scraping member 1043.

[0079] It can be understood that the main working mode of the cleaning mechanism 100 provided in the embodiment of the present application is that the driving member 1021 drives the transmission component to work. Since the transmission component is connected to the shielding member 1044, the transmission component drives the shielding member 1044 to rotate relative to the mounting member 105, thereby driving the external second scraper 1043 and the first scraper 1048 to rotate.

[0080] By inserting a protective cover 1047 inside or outside the shielding member 1044, the first gear 1046 and the second gear 1045 are protected, so that the gears are prevented from being stuck with debris and affecting normal operation, thereby improving the cleaning efficiency.

[0081] Please continue to refer to Figures 2 to 7 In a possible implementation, the transmission assembly includes a first gear 1046 and a second gear 1045 meshing with the first gear 1046, the first gear 1046 is disposed on the output shaft of the driving member 1021, and the second gear 1045 is disposed on the shielding member 1044;

[0082] The cleaning mechanism 100 further includes a protective cover 1047 , which is disposed on the shielding member 1044 to protect the second gear 1045 .

[0083] It can be understood that the back of the blade body is fixedly connected to the shielding member 1044, and the shielding member 1044 is sleeved on one side of the second gear 1045. In the embodiment of the present application, the first gear 1046 is not in contact with the shielding member 1044, and the first gear 1046 is meshed with the second gear 1045, that is, the shielding member 1044 is sleeved on the outside of the first gear 1046 and the second gear 1045, and a protective cover 1047 is also plugged in the outside or inside of the shielding member 1044. At least two through holes are provided on the protective cover 1047, which are respectively used for the installation member 105 to pass through and the output shaft of the driving member 1021 to pass through, so that the driving member 1021 outputs power to drive the second gear 1045 to rotate and then drive the cleaning blade 104 to rotate.

[0084] In addition, it should be noted that since the debris formed during the cleaning operation of the cutter disc 104 will flow into the sewage tank 103 through the sewage outlet 1042, a protective cover 1047 is inserted inside or outside the shielding member 1044 to protect the first gear 1046 and the second gear 1045, thereby preventing the gears from being stuck with debris and affecting their normal operation, thereby improving the cleaning efficiency.

[0085] Please continue to refer to Figures 2 to 7 In a possible implementation, the outer wall of the sewage tank 103 may be provided with a stop ring 1031, and the stop ring 1031 is used to abut against the inner wall of the pipeline;

[0086] And / or, at least one flushing nozzle is provided on the mounting member 105, the flushing nozzle is located on the side of the cleaning blade 104 away from the sewage tank 103, the flushing nozzle rotates relative to the mounting member 105, and the flushing nozzle is used to flush at least one of the inner wall of the pipeline and the cleaning blade 104;

[0087] And / or, further comprising a first image acquisition component 1053, the first image acquisition component 1053 being located on a side of the cleaning blade 104 away from the sewage tank 103;

[0088] The adjusting member includes a base frame 1011, an elastic member 1014 and two roller support arms 1012. The base frame 1011 is set on the support member 101. The roller support arms 1012 are rotatably set on the base frame 1011. The two roller support arms 1012 are connected by the elastic member 1014. The roller support arms 1012 are used to roll and abut against the inner wall of the pipe.

[0089] Among them, the outer diameter size of the stop ring 1031 can be selected and installed according to the inner diameter of the pipe to be cleaned. Its purpose is to form a close seal with the inner wall of the pipe through the stop ring 1031 to prevent debris or sewage formed by cleaning from flowing into the rear end of the cleaning device, thereby causing the debris formed after cleaning to remain on the inner wall of the pipe, resulting in poor cleaning effect.

[0090] Among them, the first flushing nozzle 1051 and the second flushing nozzle 1052 are respectively arranged on different axial sections of the mounting member 105, and the two have different directions, one of which is directed toward the cleaning disc 104, and the other is directed toward the inner wall of the pipe. Both flushing nozzles can rotate 360° around the mounting member 105. The flushing nozzle directed toward the cleaning disc 104 is used to flush foreign matter adhered to the second scraper 1043 on the cleaning disc 104, and the flushing nozzle directed toward the pipe is used to disperse debris deposited in the pipe. Both have the effect of improving the cleaning efficiency of the cleaning disc 104.

[0091] In addition, the mounting member 105 may further include a first image acquisition member 1053 , and the first image acquisition member 1053 is located on a side of the cleaning blade 104 facing away from the sewage tank 103 .

[0092] The first image acquisition component 1053 is arranged at the end of the mounting component 105. A transparent cover that is anti-mud and anti-fog can also be installed on the surface of the first image acquisition component 1053. The first image acquisition component 1053 can be used to observe the situation inside the pipeline, timely know the accumulation of debris in the pipeline, and adjust the steering position of the flushing nozzle to improve the cleaning efficiency.

[0093] In addition, a cable channel 106 is provided in the middle of the mounting member 105 for laying circuit cables.

[0094] By providing multiple flushing nozzles to clean the cleaning blade 104 and the residual dirt on the inner wall of the pipeline, the cleaning effect can be further increased and the cleaning efficiency can be improved.
