[0056] Referring to Figures 1-9 , one of the embodiments of the present application provides a high-pressure water self-driven low-speed nozzle, comprising:

[0057] The shell 100 has a water inlet end 110 and a cleaning end 120;

[0058] And the driving assembly 200, the speed reduction assembly 300 and the rotating assembly 400 are connected in sequence from the water inlet end 110 to the cleaning end 120 and installed inside the shell 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 shell 100 is provided with a connector 500 for connecting a high-pressure water pipe, and the shell 100 forms a water inlet cavity 130 inside through the installed connector 500, and the driving assembly 200 and the speed reduction assembly 300 are located in the water inlet cavity 130;

[0060] One end of the rotating assembly 400 is located inside the shell 100, and the other end is located at the cleaning end 120 of the shell 100 and extends outside the shell 100, and the one end of the rotating assembly 400 located inside the shell 100 is in communication with the water inlet cavity 130;

[0061] The one end of the rotating assembly 400 located outside the shell 100 is provided with a cleaning spray head 600 which is coaxially and rotationally connected and in communication.

[0062] In the embodiment, the driving assembly 200 is used to convert the direct current high-pressure water input into the shell 100 into vortex high-pressure water, and the power energy is converted from the vortex high-pressure water to drive the driving assembly 200 to rotate, and the driving assembly 200 is driven to rotate by the driving assembly 200; the speed reduction assembly 300 is used to change the transmission ratio of the driving assembly 200 to reduce the rotating speed of the rotating assembly 400, so that the time of the subsequent high-pressure water jet acting on the surface of the object to be cleaned is increased, and the impact effect is enhanced; the rotating assembly 400 is used to output high-pressure water to the cleaning spray head 600, and is used to drive the cleaning spray head 600 to rotate, so that the cleaning spray head 600 rotates and outputs high-pressure water jet to impact the surface of the object to be cleaned, so as to complete the pipeline cleaning.

[0063] In the embodiment, referring to Figures 5-9 , the cleaning spray head 600 includes a first spray head 610, a second spray head 620, a third spray head 630, a fourth spray head 640, and a fifth spray head 650, each of which is applied to different pipeline construction environments;

[0064] The first spray head 610 is applied to small-diameter pipelines and can thoroughly dredge all ranges (including pipeline dead angle positions) in small-diameter pipelines;

[0065] The second spray head 620 is applied to large-diameter pipelines and can thoroughly dredge all ranges (including pipeline dead angle positions) in large-diameter pipelines;

[0066] The third spray head 630 is a polishing spray head and is applied to the cleaning of the inner wall of the pipeline to polish and clean the obstacles on the inner wall of the pipeline.

[0067] The fourth spray head 640 is applied to small-range high-pressure water chiseling in the pipeline.

[0068] The fifth spray head 650 is applied to large-range high-pressure water chiseling in the pipeline.

[0069] Taking the first spray head 610 as an example, referring to Figure 1Specifically, the shell 100 has a water inlet end 110 and a cleaning end 120, the water inlet end 110 is used for inputting high-pressure water, and the cleaning end 120 is used for carrying the cleaning nozzle 600 to output high-pressure water jet; the connector 500 includes a water pipe threaded adapter 510 and a terminal connector 520, the terminal connector 520 is installed at the water inlet end 110 of the shell 100, one end of the water pipe threaded adapter 510 is connected with the high-pressure water pipe, and the other end is connected with the terminal connector 520; after the terminal connector 520 is installed at the water inlet end 110 of the shell 100, an internal water inlet cavity 130 (close to the water inlet end 110) of the shell 100 is formed, and the high-pressure water (direct current high-pressure water) input by the high-pressure water pipe enters the internal water inlet cavity 130 through the connector 500.

[0070] The drive assembly 200 and the speed reduction assembly 300 are sequentially (from left to right in the figure) installed in the internal water inlet cavity 130 and coaxially connected in rotation; when the high-pressure water is input into the internal water inlet cavity 130, the direct current high-pressure water is first passed through the drive assembly 200, so that the direct current high-pressure water is converted into vortex high-pressure water, the power energy is converted from the vortex high-pressure water to drive the drive assembly 200 to rotate, and the drive assembly 200 drives the speed reduction assembly 300 to rotate.

[0071] The rotating assembly 400 is installed at the internal water inlet cavity 130 of the shell 100, and the other end of the rotating assembly 400 penetrates through the cleaning end 120 of the shell 100 and is located outside the shell 100, the one end of the rotating assembly 400 close to the internal water inlet cavity 130 is coaxially connected in rotation with the speed reduction assembly 300 and the drive assembly 200, and the other end of the rotating assembly 400 located outside the shell 100 is installed with the first nozzle 610, and the first nozzle 610 is in communication with the rotating assembly 400; when the speed reduction assembly 300 is driven by the drive assembly 200, the rotating assembly 400 is driven to rotate, but due to the characteristics of the speed reduction assembly 300, the transmission ratio of the drive assembly 200 is changed, so that the rotating speed of the rotating assembly 400 is reduced, and the rotating assembly 400 maintains a low rotating speed, and the first nozzle 610 connected with the rotating assembly 400 is driven to rotate in the rotating process of the rotating assembly 400.

[0072] When the high-pressure water flows into the internal water inlet cavity 130, the drive assembly 200 is driven, and the high-pressure water also flows through the speed reduction assembly 300 and flows into the rotating assembly 400, and then is sprayed out from the first nozzle 610 in the form of high-pressure water jet to impact the surface of the object to be cleaned, and since the rotating assembly 400 maintains a low rotating speed, the time for the high-pressure water jet of the first nozzle 610 to act on the surface of the object to be cleaned is increased, so that the impact effect is enhanced, thereby increasing the cleaning effect of the pipeline.

[0073] In one embodiment, the method further comprises:

[0074] Support frame 700;

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

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

[0077] In one embodiment, several support frames 700 are arranged in a circumferential array on the outside of the housing 100.

[0078] In this embodiment, as Figure 5 As shown, several support frames 700 are arranged in a circumferential array on the outside of the housing 100, three of which are shown in the figure. There are at least three support frames 700 to ensure stability during support.

[0079] In one embodiment, it further includes:

[0080] Lubrication support assembly 800;

[0081] The housing 100 is provided with a lubrication cavity 140, which 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 is connected to the rotating assembly 400.

[0083] In this embodiment, since the rotating component 400 rotates within the housing 100 to drive the cleaning nozzle 600 to rotate accordingly, to ensure the stability of the rotating component 400, the high-pressure water self-driven low-speed nozzle of this application also includes a lubrication support component 800, such as... Figure 1 As shown, a lubrication cavity 140 is provided inside the housing 100 near the cleaning end 120. A lubrication support assembly 800 is installed in the lubrication cavity 140 and is connected to the rotating assembly 400. The lubrication support assembly 800 supports the rotating assembly 400 to ensure the stability of the rotating assembly 400 during rotation. The lubrication support assembly 800 also reduces the coefficient of friction of the rotating assembly 400 during rotation, allowing the rotating assembly 400 to rotate smoothly.

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

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

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

[0087] The lubrication cavity 140 is provided with an oil inlet 150 on its circumferential surface. The oil inlet 150 is located between the two bearings 810 and corresponds to the oil-conducting iron ring 820.

[0088] In this embodiment, the lubrication support assembly 800 includes a bearing 810 and an oil-conducting iron ring 820, such as Figure 1 As shown, there are two bearings 810, both of which are sleeved on the rotating assembly 400. The two bearings 810 are respectively located at both ends of the lubrication cavity 140 (left and right sides in the axial direction). The rotating assembly 400 is supported by the bearings 810 and the coefficient of friction during the rotation of the rotating assembly 400 is reduced.

[0089] like Figure 1 As shown, the lubrication chamber 140 is also provided with an oil inlet 150, which is located in the middle of the lubrication chamber 140. The oil inlet 150 is used to inject lubricating oil into the lubrication chamber 140 to lubricate the bearing 810. The oil-connecting ring 820 is located in the middle of the two bearings 810 and connects the two bearings 810. The position of the oil-connecting 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-connecting ring 820 to lubricate the bearings 810.

[0090] In one embodiment, both ends of the lubrication cavity 140 are provided with seals 160.

[0091] In this embodiment, as Figure 1 As shown, a seal 160 is provided at both ends of the lubrication cavity 140 to prevent lubricating oil leakage; the seal 160 is not limited to a sealing ring, and those skilled in the art can select one according to the actual use.

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

[0093] The planetary gear 310 has a plurality of planetary gears 311, and the planet 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 disposed on the drive assembly 200;

[0095] The sun gear 312 of the planetary gear 310, at the end furthest from the planet carrier 320, is connected to the drive assembly 200 and supports the drive assembly 200.

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

[0097] In this embodiment, the speed reduction assembly 300 includes a planetary gear 310, a planet carrier 320, and a connecting shaft 330. The connecting shaft 330 supports the planetary gear 310, such as... Figures 1-4 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 drive assembly 200, thereby supporting the planetary gear 310.

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

[0099] like Figures 1-4 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 drive 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 drive assembly 200, so that the direct current high-pressure water is converted into vortex high-pressure water. The vortex high-pressure water is converted into power energy to drive the drive assembly 200 to rotate. The rotating drive assembly 200 drives the sun gear 312 of the planet gear 310 to rotate, and the planet gear 311 will mesh with the sun gear 312 and the internal gear ring 313 to rotate. The planet gear 311 drives the planet carrier 320 to rotate. Then the planet carrier 320 drives the rotating assembly 400 to rotate. Due to the characteristics of the planet gear 310, the rotation speed of the rotating assembly 400 is reduced, so that the rotating assembly 400 maintains a low rotation speed.

[0100] Meanwhile, 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 in through the through hole in the middle of the planetary carrier 320 into the rotating assembly 400.

[0101] In one embodiment, the drive assembly 200 includes a slanted disc 210 and an impeller 220;

[0102] The surface of the inclined hole disc 210 has several inclined holes;

[0103] The inclined hole disc 210 is installed in the water inlet cavity 130 and close to the joint 500, and the inclined 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 cavity 130, and the impeller 220 is located at the end of the inclined hole disc 210 away from the joint 500, and the impeller 220 is sleeved on the 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 the inclined hole disc 210 and the impeller 220, as Figures 1-4 The surface of the inclined hole disc 210 has several inclined holes, the inclined hole disc 210 is installed in the water inlet cavity 130 of the shell 100, that is, at the end of the terminal joint 520 away from the water pipe threaded adapter 510, and the inclined hole disc 210 is connected with the end of the connecting shaft 330 away from the sun gear 312, the inclined hole disc 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 cavity 130 of the shell 100, located between the planetary gear 310 and the inclined hole disc 210, the impeller 220 is sleeved on the end of the sun gear 312 away from the planet carrier 320, and the impeller 220 is connected with the end of the sun gear 312 through a key, so as 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 shell 100, the high-pressure water first enters the water inlet cavity 130 of the shell 100 through the joint 500, the high-pressure water entering the water inlet cavity 130 first passes through the inclined hole disc 210 and the inclined holes of the inclined hole disc 210, and is sprayed to the position of the impeller 220, the inclined holes on the inclined hole disc 210 play a role in increasing the jet speed of the high-pressure water, and at the same time, can convert the direct-current high-pressure water into vortex high-pressure water, which is sprayed to the blades of the impeller 220, 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 and the sun gear 312 and the inner ring gear 313 to rotate in meshing, the planet carrier 320 is driven to rotate by the planetary gear 311, and the rotating assembly 400 is driven to rotate by the planet carrier 320, due to the characteristics of the planetary gear 310, the rotating speed of the rotating assembly 400 is reduced, so that the rotating assembly 400 maintains a relatively low rotating speed.

[0107] In this embodiment, the impeller 220 is the main driving component, which drives the other components to rotate. The impeller 220 does not require an additional power source. Through ingenious design, this application makes the whole system self-driven, self-reducing, speed adjustable, and compact. Furthermore, since no additional power source is required, it also has an energy-saving effect.

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

[0109] The housing 100 has an installation cavity 170 inside near the cleaning end 120, and one end of the planetary carrier 320 away from the internal gear ring 313 of the planetary gear 310 passes through the water inlet cavity 130 and is located in the installation cavity 170.

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

[0111] In this embodiment, the rotating assembly 400 includes a rotating body 410, such as... Figure 1 As shown, the rotating body 410 has a through water outlet channel 411 inside, and the housing 100 near the cleaning end 120 has a mounting cavity 170. This mounting cavity 170 is similar in shape to the rotating body 410 to accommodate its installation. One end of the planetary carrier 320 away from the internal gear ring 313 of the planetary gear 310 passes through the water inlet cavity 130 and is located in the mounting cavity 170. Figure 4 As shown, the planetary carrier 320 has a rectangular design at this end. The rotating body 410 is installed inside the housing 100 through the mounting cavity 170. One end of the rotating body 410 is connected to the end of the planetary carrier 320 located in the mounting cavity 170, and the other end extends from the mounting cavity 170 to the outside of the housing 100. Since the planetary carrier 320 has a rectangular design at this end, 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 mounted on one end of the rotating body 410 located outside the housing 100, and the cleaning nozzle 600 is connected to the water outlet channel 411 of the rotating body 410.

[0113] In this embodiment, as Figure 1 ,Figure 5 As shown, taking the first spray head 610 as an example, the first spray head 610 is installed on one end of the rotating body 410 outside the shell 100, and the first spray head 610 is communicated with 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 is sprayed from the first spray head 610 in the form of high-pressure water jet to strike the surface of the object to be cleaned. Since the rotating body 410 rotates at a low speed, the time for the high-pressure water jet of the first spray head 610 to act on the surface of the object to be cleaned is increased, so that the striking effect is enhanced, thereby increasing the cleaning effect of the pipeline.

[0114] According to the needs, the above-mentioned installation, arrangement, provision or connection modes include, but are not limited to, screwing, riveting, welding or sleeving, fixing and the like, and the installation, arrangement or connection modes are selected according to the working situation.
