Description

Technical Field

[0001] This utility model belongs to the field of pipeline cleaning technology, specifically a high-pressure pipeline cleaning component. Background Technology

[0002] In sewage discharge pipes and other fluid discharge pipes, the accumulation of dirt on the pipe walls necessitates regular cleaning to ensure unobstructed flow. Current pipe cleaning processes utilize pipe nozzles, which spray high-pressure cleaning fluid to remove deposits from the pipe walls. While existing nozzles offer various nozzle orifice sizes to suit different pipe types and deposit conditions for effective cleaning, their fixed orifice sizes necessitate nozzle replacement for different deposit types, resulting in time-consuming, labor-intensive, and costly cleaning. Utility Model Content

[0003] To address the technical problems existing in the background art, this utility model proposes a high-pressure pipe cleaning component, which can adjust the cleaning intensity and the moving speed inside the target pipe, is suitable for different pipes and adapts to different deposition conditions, and ensures the cleaning effect.

[0004] The objective of this utility model can be achieved through the following technical solutions:

[0005] A high-pressure pipe cleaning assembly is installed at the front end of a cleaning hose supplying high-pressure cleaning fluid. The assembly moves within a target pipe through the jetting of the high-pressure cleaning fluid, cleaning the inside of the pipe. The assembly includes a main body and a column. The main body has a receiving cavity communicating with the hose to introduce the cleaning fluid. The side wall of the main body has a first jetting hole group and a second jetting hole group communicating with the inside and outside of the receiving cavity. The column is installed within the receiving cavity and can move axially within the cavity. The column has a flow channel, one end of which is open and communicates with the receiving cavity, while the other end of the flow channel is blocked by the end of the column. The side wall of the column has a through hole communicating with the inside and outside of the flow channel. A ball, a rod, and a spring are installed within the receiving cavity near the end of the column. The inner wall of the receiving cavity near the end of the column includes a machined surface parallel to the axis of the column, where a guide is machined. The ball is assembled in the guide groove and can move along the extension direction of the guide groove. One end of the rod is hinged to the ball, and the other end of the rod is hinged to the end of the column. One end of the spring abuts against the inner wall of the receiving cavity and is fixed in position, and the other end of the spring abuts against the end of the column. After switching between turning off the cleaning fluid input and turning on the cleaning fluid input once or multiple times and returning to the continuous input of the cleaning fluid, the ball will switch between the first stopping position / second stopping position in the guide groove and the second stopping position / first stopping position in the guide groove. When the ball stops at the first stopping position, the first jet hole group is connected to the flow channel through the through hole, and the outer wall of the column blocks the second jet hole group. When the ball stops at the second stopping position, the second jet hole group is connected to the flow channel through the through hole, and the outer wall of the column blocks the first jet hole group.

[0006] Furthermore, there is a first hinge point between the end of the column and the rod, and the first projection length of the first line connecting the first stopping position and the first hinge point in the axial direction of the column is greater than the second projection length of the second line connecting the second stopping position and the first hinge point in the axial direction of the column.

[0007] Furthermore, both the first and second stopping positions are located at the inflection points furthest from the end of the column within the section. The guide groove is closed at both ends. The guide groove has a first guide groove section and a second guide groove section connecting the first and second stopping positions. The first guide groove section has a first inflection point closest to the end of the column within the section, and the second guide groove section has a second inflection point closest to the end of the column within the section.

[0008] Furthermore, the curvature of the portion of the first guide groove near the first stopping position is less than the curvature of the portion of the second guide groove near the first stopping position; in the direction from the first stopping position to the second stopping position after passing through the first inflection point, the curvature of the portion of the groove upstream of the first inflection point is greater than the curvature of the portion of the groove downstream of the first inflection point; in the direction from the second stopping position to the first stopping position after passing through the second inflection point, the curvature of the portion of the groove upstream of the second inflection point is greater than the curvature of the portion of the groove downstream of the second inflection point; and the curvature of the portion of the first guide groove near the second stopping position is greater than the curvature of the portion of the second guide groove near the second stopping position.

[0009] Furthermore, when the cleaning fluid switches from the open state to the closed state, the spring rebound will push the column to move axially. The axial movement of the column will, through the linkage of the rod, move the ball at the first stop position / second stop position along the first guide groove section / second guide groove section to the first inflection point / second inflection point to form abutment.

[0010] Furthermore, when the cleaning fluid is switched from the closed state to the open state, the pressure of the cleaning fluid will overcome the spring force and push the column to move axially. The axial movement of the column will, through the linkage of the rod, move the ball at the first inflection point / second inflection point along the first guide groove section / second guide groove section to the second stopping position / first stopping position to form abutment.

[0011] Furthermore, during the movement of the rod, the axial direction of the rod is always parallel to the machined surface.

[0012] The beneficial effects of this utility model are as follows: The high-pressure pipe cleaning assembly provided in this application has a column coaxially sleeved inside the main body, and multiple sets of different types of spray holes are opened on the side wall of the main body. Through holes communicating with the internal flow channel are opened on the side wall of the column. The column is driven to move axially within the main body by the pressure of the high-pressure cleaning fluid and the elastic force of the spring. By connecting the column with a ball that moves in the guide groove, the axial movement position of the column is restricted by the stopping position of the ball in the guide groove. The through holes can be connected to multiple sets of spray holes to form multiple different channels, driving the cleaning assembly to move inside the target pipe and clean the inside of the target pipe. By setting the multiple sets of spray holes to different diameters or tilt angles, the spray volume of the high-pressure cleaning fluid and the spray angle relative to the inner circumference of the target pipe can be changed, thereby adjusting the cleaning intensity and the moving speed of the cleaning assembly inside the target pipe. This makes it suitable for different pipes and adaptable to different deposition conditions to ensure the cleaning effect. Attached Figure Description

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0018] like Figure 1-4 As shown, this utility model provides a high-pressure pipe cleaning assembly, installed at the front end of a cleaning hose supplying high-pressure cleaning fluid. The high-pressure cleaning fluid is sprayed and moves inside the target pipe, cleaning its interior. The cleaning assembly includes: a main body 1 and a column 2. The column 2 is coaxially arranged with the main body 1, and its outer wall is fitted against the inner wall of the main body 1. The main body 1 has a receiving cavity 3 communicating with the hose to introduce the cleaning fluid. The column 2 is installed in the receiving cavity 3 and can move axially within it. The column 2 has a flow channel 4, one end of which is open and communicates with the receiving cavity 3, allowing the high-pressure cleaning fluid entering the receiving cavity 3 to flow into the flow channel 4. The other end of the flow channel 4 is blocked by the end of the column 2.

[0019] The side wall of the main body 1 is provided with a first jet hole group 11 and a second jet hole group 12 that penetrate the side wall of the main body 1 to connect the inside and outside of the receiving cavity 3. The first jet hole group 11 and the second jet hole group 12 are arranged sequentially along the axial direction of the main body 1. The first jet hole group 11 includes a plurality of first jet holes evenly distributed along the circumference of the main body 1, and the second jet hole group 12 includes a plurality of second jet holes evenly distributed along the circumference of the main body 1. The side wall of the column 2 is provided with one or more through holes 21 that connect the inside and outside of the flow channel 4. The outer wall of the column 2 is slidably connected to the inner wall of the main body 1.

[0020] Inside the storage cavity 3, near the end of the column 2, there is a ball 5, a rod 6, and a spring. The inner wall of the storage cavity 3 near the end of the column 2 includes a machined surface 8 parallel to the axis of the column 2. A guide groove 7 that is closed at both ends is machined on the machined surface 8. The ball 5 is assembled in the guide groove 7 and can move in the guide groove 7 along the extension direction of the guide groove 7. One end of the rod 6 is hinged to the ball 5, and the other end of the rod 6 is hinged to the end of the column 2. One end of the spring abuts against the inner wall of the storage cavity 3 and is fixed in position, and the other end of the spring abuts against the end of the column 2. Specifically, there is a first hinge point between the end of the column 2 and the rod 6. The first projection length of the first line connecting the first stopping position 71 and the first hinge point in the axial direction of the column 2 is greater than the second projection length of the second line connecting the second stopping position 72 and the first hinge point in the axial direction of the column 2. Thus, the axial movement of the column 2 in the receiving cavity 3 is restricted by the stopping position of the ball 5 in the guide groove 7, and the axial direction of the rod 6 is always parallel to the processing surface 8 during the movement of the rod 6.

[0021] When high-pressure cleaning fluid is input into the flow channel 4, the high-pressure cleaning fluid will push the column 2 to move axially within the receiving cavity 3 against the spring force. At the same time, the rod 6 will drive the ball 5 to move from the first stopping position 71 to the second stopping position 72, or from the second stopping position 72 to the first stopping position 71, within the guide groove 7. After switching between turning off and turning on the cleaning fluid input once or multiple times and returning to continuous input of the cleaning fluid, the ball 5 will switch between stopping at the first stopping position 71 / second stopping position 72 and stopping at the second stopping position 72 / first stopping position 71 within the guide groove 7. When the ball 5 stops at the first stopping position 71, the first injection hole group 11 communicates with the flow through the through hole 21. The first channel is formed by connecting the channel 4, while the outer wall of the column 2 blocks the second spray hole group 12. When the ball 5 stops at the second stopping position 72, the second spray hole group 12 connects with the channel 4 through the through hole 21 to form the second channel. At the same time, the outer wall of the column 2 blocks the first spray hole group 11, so that the high-pressure cleaning fluid in the channel 4 switches between being sprayed outward through the first channel and being sprayed outward through the second channel, driving the cleaning component to move inside the target tube and clean the inside of the target tube. By setting the first external spray hole and the second external spray hole to different apertures or tilt angles, the spray volume of the high-pressure cleaning fluid and the spray angle relative to the inner circumference of the target tube can be changed, thereby adjusting the cleaning intensity of the cleaning component and the moving speed inside the target tube.

[0022] Specifically, the first stopping position 71 and the second stopping position 72 are both located at the inflection point furthest from the end of the column 2 within the section. The guide groove 7 has a first guide groove section 73 and a second guide groove section 74 connecting the first stopping position 71 and the second stopping position 72. The first guide groove section 73 has a first inflection point 75 closest to the end of the column 2 within the section, and the second guide groove section 74 has a second inflection point 76 closest to the end of the column 2 within the section.

[0023] The curvature of the portion of the first guide groove 73 near the first stopping position 71 is less than the curvature of the portion of the second guide groove 74 near the first stopping position 71, so that when the sphere 5 touches the first stopping position 71, its center of gravity moves from the second guide groove 74 into the first guide groove 73; in the direction from the first stopping position 71 to the second stopping position 72, after passing the first inflection point 75, the curvature of the portion of the groove upstream of the first inflection point 75 is greater than the curvature of the portion of the groove downstream of the first inflection point 75, so that when the sphere 5 touches the first inflection point 75, its center of gravity moves from the portion of the groove upstream of the first inflection point 75 into the portion of the groove downstream of the first inflection point 75; The curvature of the portion of the first guide groove 73 near the second stopping position 72 is greater than the curvature of the portion of the second guide groove 74 near the second stopping position 72, so that when the sphere 5 touches the second stopping position 72, its center of gravity moves from the first guide groove 73 into the second guide groove 74; in the direction from the second stopping position 72 to the first stopping position 71, after passing the second inflection point 76, the curvature of the portion of the groove upstream of the second inflection point 76 is greater than the curvature of the portion of the groove downstream of the second inflection point 76, so that when the sphere 5 touches the second inflection point 71, its center of gravity moves from the portion of the groove upstream of the second inflection point 76 into the portion of the groove downstream of the second inflection point 76.

[0024] Therefore, when the cleaning fluid input is switched on and off repeatedly, the sphere 5 will circulate along the guide groove 7. The specific circulation process is as follows:

[0025] Sphere 5 initially rests against the second inflection point 71.

[0026] When the cleaning fluid switches from the off state to the on state, the pressure of the cleaning fluid will overcome the spring force and push the column 2 to move axially. The axial movement of the column 2 will, through the rod 6, move the ball 5 located at the second inflection point 76 along the second guide groove section 74 to the first stopping position 71 to form a stop. Figure 1 As shown, the first injection hole group 11 is connected to the flow channel 4 through the through hole 21 to form a first channel, while the outer wall of the column 2 blocks the second injection hole group 12.

[0027] When the cleaning fluid switches from the on state to the off state, the spring rebound will push the column 2 to move axially. The axial movement of the column 2 will, through the rod 6, move the ball 5, which is in the first stopping position 71, along the first guide groove section 73 to the first inflection point 75 to form abutment. Figure 2 As shown, the outer wall of column 2 forms a seal against the first injection hole group 11 and the second injection hole group 12.

[0028] When the cleaning fluid switches from the off state back to the on state, the pressure of the cleaning fluid will overcome the spring force and push the column 2 to move axially. The axial movement of the column 2 will, through the rod 6, move the ball 5 located at the first inflection point 75 along the first guide groove section 73 to the second stopping position 72 to form a stop. Figure 3 As shown, the second jet hole group 12 is connected to the flow channel 4 through the through hole 21 to form the first channel, while the outer wall of the column 2 blocks the first jet hole group 11.

[0029] When the cleaning fluid switches from the open state back to the closed state, the spring rebound will push the column 2 to move axially. The axial movement of the column 2 will, through the rod 6, move the ball 5, which is in the second stopping position 72, along the second guide groove section 74 to the second inflection point 76 to form abutment. Figure 4 As shown, the outer wall of column 2 forms a seal against the first injection hole group 11 and the second injection hole group 12.

[0030] The above description is merely an example and illustration of the structure of this utility model. Those skilled in the art can make various modifications or additions to the specific embodiments described or use similar methods to replace them, as long as they do not deviate from the structure of the utility model or exceed the scope defined in the claims, they should all fall within the protection scope of this utility model.
