[0002] Urban drainage is an important and indispensable infrastructure for modern cities, and has a global and leading impact on urban economic development. It is also a backbone project for urban water pollution prevention and control and urban drainage, waterlogging and flood control. With the development of the economy and the continuous gathering of urban population, the drainage pressure of urban drainage channels is increasing day by day, while the new and rebuilt municipal sewer projects are far from meeting the demand. The problems exposed in the field of urban drainage are becoming increasingly prominent. Poor drainage will affect the daily life of residents at the least, and will disrupt the normal rhythm of the entire city in serious cases. Urban drainage facilities are not only an important prerequisite for maintaining the metabolic function of urban ecological substances, but also an important measure to protect urban water quality resources and living environment.

[0056] Reference Figure 8-Figure 16 One embodiment of the present invention provides a high-pressure water self-driven low-speed cleaning device, comprising:

[0057] A housing 100 having a water inlet end 110 and a cleaning end 120;

[0058] And, a driving assembly 200, a speed reduction assembly 300 and a rotating assembly 400 are sequentially connected from the water inlet end 110 to the cleaning end 120 and installed inside the housing 100, and the driving assembly 200, the speed reduction assembly 300 and the rotating assembly 400 rotate coaxially;

[0059] The water inlet end 110 of the housing 100 is installed with a joint 500 for connecting a high-pressure water pipe, and a water inlet chamber 130 is formed inside the housing 100 through the installed joint 500. The driving assembly 200 and the speed reduction assembly 300 are both located in the water inlet chamber 130.

[0060] One end of the rotating assembly 400 is located inside the housing 100, and the other end is located at the cleaning end 120 of the housing 100 and extends to the outside of the housing 100. The end of the rotating assembly 400 located inside the housing 100 is connected to the water inlet chamber 130.

[0061] The end of the rotating assembly 400 located outside the housing 100 is provided with a cleaning nozzle 600 which is coaxially rotatably connected and communicated with the housing 100 .

[0062] In this embodiment, the driving component 200 is used to convert the direct current high-pressure water in the input shell 100 into eddy current high-pressure water, and the eddy current high-pressure water is converted into kinetic energy to drive the driving component 200 to rotate, and the rotating driving component 200 drives the deceleration component 300; the deceleration component 300 is used to change the transmission ratio of the driving component 200 to reduce the rotation speed of the rotating component 400, so that the subsequent high-pressure water jet acts on the surface of the object to be cleaned for a longer time, thereby enhancing the striking effect; the rotating component 400 is used to output high-pressure water to the cleaning nozzle 600, and is used to drive the cleaning nozzle 600 to rotate, so that the cleaning nozzle 600 rotates and outputs a high-pressure water jet to strike the surface of the object to be cleaned, so as to complete the pipeline cleaning.

[0063] In this embodiment, refer to Figure 12-16 The cleaning nozzle 600 includes a first nozzle 610, a second nozzle 620, a third nozzle 630, a fourth nozzle 640 and a fifth nozzle 650, each nozzle being applied to a different pipeline construction environment;

[0064] The first nozzle 610 is applied to small-diameter pipelines and can thoroughly desilt all areas in the small-diameter pipelines (including dead corners of the pipelines);

[0065] The second nozzle 620 is applied to large-diameter pipelines and can thoroughly desilt all areas in the large-diameter pipelines (including dead corners of the pipelines);

[0066] The third nozzle 630 is a polishing nozzle, which is used to clean the inner wall of the pipeline and polish and clean obstacles on the inner wall of the pipeline;

[0067] The fourth nozzle 640 is used for high-pressure water chiseling and roughening in a small area of ​​the pipeline;

[0068] The fifth nozzle 650 is used for large-scale high-pressure water chiseling and roughening in pipelines.

[0069] Taking the first nozzle 610 as an example, refer to Figure 8 Specifically, the shell 100 has a water inlet end 110 and a cleaning end 120, the water inlet end 110 is used to input high-pressure water, and the cleaning end 120 is used to carry a cleaning nozzle 600 to output a high-pressure water jet; the joint 500 includes a water pipe threaded adapter 510 and an end joint 520, and the end joint 520 is installed at the water inlet end 110 of the shell 100, one end of the water pipe threaded adapter 510 is connected to the high-pressure water pipe, and the other end is connected to the end joint 520; when the end joint 520 is installed at the water inlet end 110 of the shell 100, a water inlet chamber 130 is formed inside the shell 100 (near the water inlet end 110), and the high-pressure water (direct current high-pressure water) input by the high-pressure water pipe enters the water inlet chamber 130 through the joint 500.

[0070] The driving assembly 200 and the deceleration assembly 300 are sequentially installed in the water inlet chamber 130 (from left to right in the figure), and the two are coaxially connected for rotation; when high-pressure water is input into the water inlet chamber 130, it will first pass through the driving assembly 200, so that the direct high-pressure water is converted into eddy current high-pressure water, and the eddy current high-pressure water is converted into kinetic energy to drive the driving assembly 200 to rotate, and the rotating driving assembly 200 drives the deceleration assembly 300;

[0071] The rotating assembly 400 is installed inside the shell 100 near the cleaning end 120, one end of the rotating assembly 400 is close to the water inlet chamber 130, and the other end passes through the cleaning end 120 of the shell 100 and is located outside the shell 100. The end of the rotating assembly 400 close to the water inlet chamber 130 is coaxially connected with the deceleration assembly 300 and the driving assembly 200 for rotation, and the first nozzle 610 is installed at the end of the rotating assembly 400 located outside the shell 100, and the installed first nozzle 610 maintains a connected state with the rotating assembly 400; when the deceleration assembly 300 is driven by the driving assembly 200, it will drive the rotating assembly 400 to rotate, but due to the characteristics of the deceleration assembly 300, the transmission ratio of the driving assembly 200 will be changed, so that the rotation speed of the rotating assembly 400 will be reduced, so that the rotating assembly 400 maintains a low rotation speed, and during the rotation of the rotating assembly 400, it will drive the first nozzle 610 connected thereto to rotate;

[0072] When high-pressure water flows into the water inlet chamber 130, while driving the driving component 200, it also passes through the speed reduction component 300 and flows into the rotating component 400, and then is sprayed out from the first nozzle 610 in the form of a high-pressure water jet to strike the surface of the object to be cleaned. Since the rotating component 400 maintains a low rotation speed, the time that the high-pressure water jet of the first nozzle 610 acts on the surface of the object to be cleaned will increase, so that the striking effect is enhanced, thereby increasing the effect of pipeline cleaning.

[0073] In one embodiment, it also includes:

[0074] Support frame 700;

[0075] The support frame 700 is installed outside the housing 100 .

[0076] In this embodiment, since the high-pressure water jet will generate a large recoil force when the overall equipment is operating in the pipeline, in order to ensure that the overall equipment can operate normally, a support frame 700 is set on the outside of the shell 100 to provide support force and overcome the generated recoil force, so as to ensure that the overall equipment can be supported in the pipeline and work normally.

[0077] In one embodiment, a plurality of support frames 700 are arranged in an array on the outer circumference of the housing 100 .

[0078] In this embodiment, if Fig.12 As shown, a plurality of support frames 700 are arranged in a circumferential array outside the shell 100 , three in the figure, and there are at least three support frames 700 to ensure stability during support.

[0079] In one embodiment, it also includes:

[0080] Lubricate support assembly 800;

[0081] The housing 100 is provided with a lubrication cavity 140 , and the lubrication cavity 140 is close to the cleaning end 120 of the housing 100 ;

[0082] The lubrication support assembly 800 is installed in the lubrication cavity 140 and connected to the rotating assembly 400 .

[0083] In this embodiment, since the rotating assembly 400 rotates in the housing 100 to drive the cleaning nozzle 600 to rotate accordingly, in order to ensure the stability of the rotating assembly 400, the high-pressure water self-driven low-speed cleaning device of the present application also includes a lubrication support assembly 800, such as Figure 8 As shown, a lubrication cavity 140 is provided inside the shell 100 near the cleaning end 120, and a lubrication support assembly 800 is installed in the lubrication cavity 140, and the lubrication support assembly 800 is connected to the rotating assembly 400. The lubrication support assembly 800 is provided to support the rotating assembly 400 to ensure the stability of the rotating assembly 400 during rotation, and the lubrication support assembly 800 is provided to reduce the friction coefficient of the rotating assembly 400 during rotation, so that the rotating assembly 400 can rotate smoothly.

[0084] In one embodiment, the lubrication support assembly 800 includes a bearing 810 and an oil-permeable iron ring 820;

[0085] Bearings 810 are disposed at both ends of the lubrication cavity 140, and the bearings 810 are sleeved on the rotating assembly 400;

[0086] The oil-permeable iron ring 820 is disposed between the two bearings 810;

[0087] An oil inlet 150 is disposed on the circumferential surface of the lubrication cavity 140 . The oil inlet 150 is located between the two bearings 810 and corresponds to the oil passing iron ring 820 .

[0088] In this embodiment, the lubrication support assembly 800 includes a bearing 810 and an oil-permeable iron ring 820. Figure 8 As shown, there are two bearings 810, both of which are sleeved on the rotating assembly 400, and the two bearings 810 are respectively arranged at the two ends of the lubrication cavity 140 (the left side and the right side in the axial direction), and the rotating assembly 400 is supported by the arranged bearings 810, and the friction coefficient of the rotating assembly 400 during the rotation process is reduced;

[0089] like Figure 8As shown, the lubrication cavity 140 is also provided with an oil inlet 150, and the oil inlet 150 is located in the middle of the lubrication cavity 140. The oil inlet 150 is used to inject lubricating oil into the lubrication cavity 140 to lubricate the bearing 810; the oil-passing iron ring 820 is arranged in the middle of the two bearings 810 and connects the two bearings 810, and the position of the oil-passing iron ring 820 corresponds to the position of the oil inlet 150, so that the lubricating oil injected into the oil inlet 150 can be evenly distributed to the bearings 810 on both sides through the oil-passing iron ring 820 to lubricate the bearings 810.

[0090] In one embodiment, sealing members 160 are disposed at both ends of the lubrication cavity 140 .

[0091] In this embodiment, if Figure 8 As shown, seals 160 are respectively provided at both ends of the lubrication cavity 140 to prevent the lubricating oil from leaking out; the seal 160 is not limited to a sealing rubber ring, and those skilled in the art can select it according to actual usage.

[0092] In one embodiment, the speed reduction assembly 300 includes a planetary gear 310, a planetary carrier 320, and a connecting shaft 330;

[0093] The planetary gear 310 has a plurality of planetary wheels 311, and the planetary carrier 320 has a through hole in the middle;

[0094] The sun gear 312 of the planetary gear 310 is sleeved on one end of the connecting shaft 330, and the other end of the connecting shaft 330 is arranged on the driving assembly 200;

[0095] One end of the sun gear 312 of the planetary gear 310 away from the planet carrier 320 is connected to the driving assembly 200 and supports the driving assembly 200;

[0096] One end of the planet carrier 320 away from the inner gear ring 313 of the planetary gear 310 is connected to the rotating assembly 400 , and this end of the planet carrier 320 is attached to the end surface of the water inlet chamber 130 .

[0097] In this embodiment, the speed reduction assembly 300 includes a planetary gear 310, a planetary carrier 320, and a connecting shaft 330. The connecting shaft 330 is used to support the planetary gear 310. Figure 8-Figure 11 , as shown, the sun gear 312 of the planetary gear 310 is sleeved on one end of the connecting shaft 330, and the other end of the connecting shaft 330 passes through the sun gear 312 and is connected to the driving assembly 200, so as to support the planetary gear 310;

[0098] The planetary gear 310 has at least two planetary wheels 311, and in this embodiment, there are three planetary wheels 311. The planetary carrier 320 has the same number of connection points as the planetary wheels 311, and the planetary carrier 320 has a through hole in the middle. When the planetary carrier 320 is connected to the planetary wheels 311, a gap is left between the planetary carrier 320 and the planetary wheels 311, so that subsequent high-pressure water can flow through the through hole in the middle of the planetary carrier 320.

[0099] like Figure 8-Figure 11 As shown, the end of the sun gear 312 away from the planet carrier 320 (i.e., the left side in the figure) is connected to the driving assembly 200, and the end of the planet carrier 320 away from the sun gear 312 is connected to the rotating assembly 400 (i.e., the right side in the figure). When high-pressure water is input into the water inlet chamber 130, it will first pass through the driving assembly 200, so that the direct current high-pressure water is converted into eddy current high-pressure water, and the eddy current high-pressure water is converted into kinetic energy to drive the driving assembly 200 to rotate, and the rotating driving assembly 200 drives the sun gear 312 of the planetary gear 310 to rotate, and the planetary gear 311 will mesh with the sun gear 312 and the inner ring gear 313 to rotate, and the planetary gear 311 drives the planetary carrier 320 to follow the rotation, and then the planetary carrier 320 drives the rotating assembly 400 to follow the rotation. Due to the characteristics of the planetary gear 310, the rotation speed of the rotating assembly 400 is reduced, so that the rotating assembly 400 maintains a relatively low rotation speed;

[0100] At the same time, the high-pressure water entering the water inlet chamber 130 will flow to the gap between the planetary gear 311 and the planetary carrier 320 , and flow into the rotating assembly 400 from the through hole in the middle of the planetary carrier 320 .

[0101] In one embodiment, the driving assembly 200 includes an inclined hole disc 210 and an impeller 220;

[0102] The surface of the inclined hole disk 210 has a plurality of inclined holes;

[0103] The oblique hole disc 210 is installed in the water inlet chamber 130 and close to the joint 500, and the oblique hole disc 210 is sleeved on the end of the connecting shaft 330 away from the planet carrier 320;

[0104] The impeller 220 is installed in the water inlet chamber 130 , and is located at one end of the inclined hole disc 210 away from the joint 500 , and the impeller 220 is sleeved on one end of the sun gear 312 of the planetary gear 310 away from the planet carrier 320 .

[0105] In this embodiment, the driving assembly 200 includes an inclined hole disc 210 and an impeller 220. Figure 8-Figure 11As shown, the surface of the inclined hole disk 210 has a plurality of inclined holes. The inclined hole disk 210 is installed in the water inlet chamber 130 of the housing 100, that is, located at the end of the end joint 520 away from the water pipe threaded adapter 510, and the inclined hole disk 210 is connected to the end of the connecting shaft 330 away from the sun gear 312. The inclined hole disk 210 also plays a supporting role, supporting the connecting shaft 330, thereby supporting the planetary gear 310; the impeller 220 is also installed in the water inlet chamber 130 of the housing 100, located between the planetary gear 310 and the inclined hole disk 210, and the impeller 220 is sleeved on the end of the sun gear 312 away from the planetary carrier 320, and the impeller 220 is connected to the end of the sun gear 312 by a key to ensure that the sun gear 312 can rotate coaxially with the impeller 220.

[0106] When the high-pressure water pipe inputs high-pressure water (direct current high-pressure water) into the housing 100, the high-pressure water first enters the water inlet chamber 130 of the housing 100 through the joint 500. The high-pressure water entering the water inlet chamber 130 first passes through the inclined hole disc 210 and is sprayed to the position where the impeller 220 is located through the inclined hole of the inclined hole disc 210. The inclined hole on the inclined hole disc 210 increases the injection speed of the high-pressure water. At the same time, the direct current high-pressure water can be converted into eddy current high-pressure water, which is sprayed to the impeller 220. The impeller 220 has blades, so that the impeller 220 rotates, and the rotating impeller 220 drives the sun gear 312 to rotate coaxially, and drives the planetary gear 311 to mesh with the sun gear 312 and the inner ring gear 313 to rotate, and the planetary gear 311 drives the planetary carrier 320 to rotate, and then the planetary carrier 320 drives the rotating component 400 to rotate. Due to the characteristics of the planetary gear 310, the rotation speed of the rotating component 400 is reduced, so that the rotating component 400 maintains a lower rotation speed.

[0107] In this embodiment, the impeller 220 is the main driving component to drive the remaining components to rotate, and the drive of the impeller 220 does not require an additional power source. Through clever design, the present application makes the whole have the characteristics of self-drive, self-deceleration, adjustable speed, compact structure, etc., and since no additional power source is required, it also has the effect of energy saving.

[0108] In one embodiment, the rotating assembly 400 includes a rotating body 410, and a water outlet channel 411 is disposed inside the rotating body 410;

[0109] The housing 100 is provided with a mounting cavity 170 near the cleaning end 120, and one end of the planetary carrier 320 away from the inner gear ring 313 of the planetary gear 310 passes through the water inlet cavity 130 and is located in the mounting cavity 170;

[0110] The rotating body 410 is installed in the installation cavity 170, and one end of the rotating body 410 is sleeved on one end of the planetary frame 320 located in the installation cavity 170, and the other end of the rotating body 410 extends from the installation cavity 170 to the outside of the shell 100, and the rotating body 410 is connected to the through hole of the planetary frame 320 through the water outlet channel 411.

[0111] In this embodiment, the rotating assembly 400 includes a rotating body 410, such as Figure 8 As shown, the rotating body 410 has a through water outlet channel 411, and the housing 100 is provided with a mounting cavity 170 near the cleaning end 120. The mounting cavity 170 is similar in shape to the rotating body 410 to adapt to the installation of the rotating body 410; one end of the planetary carrier 320 away from the inner gear ring 313 of the planetary gear 310 passes through the water inlet cavity 130 and is located in the mounting cavity 170, as shown in FIG. Fig.11 As shown, this end of the planetary carrier 320 is designed in a rectangular shape, and the rotating body 410 is installed inside the shell 100 through the installation cavity 170, and one end of the rotating body 410 is socketed with one end of the planetary carrier 320 located in the installation cavity 170, and the other end extends from the installation cavity 170 to the outside of the shell 100. Since this end of the planetary carrier 320 is designed in a rectangular shape, when the planetary carrier 320 rotates, it will drive the rotating body 410 to rotate coaxially. At the same time, the through hole of the planetary carrier 320 corresponds to the water outlet channel 411 of the rotating body 410. When the high-pressure water in the water inlet cavity 130 flows through the through hole of the planetary carrier 320, the high-pressure water will directly enter the water outlet channel 411 of the rotating body 410.

[0112] In one embodiment, the cleaning nozzle 600 is installed on one end of the rotating body 410 located outside the shell 100, and the cleaning nozzle 600 is connected to the water outlet channel 411 of the rotating body 410.

[0113] In this embodiment, if Figure 8 , Fig.12 As shown, taking the first nozzle 610 as an example, the first nozzle 610 is installed on one end of the rotating body 410 located outside the shell 100, and the first nozzle 610 is connected to the water outlet channel 411 of the rotating body 410. The high-pressure water flowing into the water outlet channel 411 of the rotating body 410 will be sprayed out from the first nozzle 610 in the form of a high-pressure water jet to strike the surface of the object to be cleaned. Since the rotating body 410 keeps rotating at a low speed, the time that the high-pressure water jet of the first nozzle 610 acts on the surface of the object to be cleaned will increase, so that the striking effect is enhanced, thereby increasing the effect of pipeline cleaning.

[0114] As needed, the above-mentioned installation, setting, provision or connection methods include but are not limited to installation, setting or connection by screws, riveting, welding or socketing, fixing, etc., and the installation, setting or connection method is selected according to the needs of the working scenario.
