[0032] The present invention is further described in detail below in conjunction with the accompanying drawings so that those skilled in the art can implement the invention with reference to the description.

[0033] It should be noted that the experimental methods described in the following embodiments are conventional methods unless otherwise specified, and the reagents and materials are commercially available unless otherwise specified; in the description of the present invention, the terms "lateral", "longitudinal", "upper", "lower", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside" and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0034] like Figures 1 to 2 As shown, the present invention provides a high-pressure gas silt clearing method based on the impact disturbance principle, which performs high-pressure gas impact disturbance on the silt in the sewage pipe 1 to achieve the movement of the silt with the water flow.

[0035] Specifically, a high-pressure air pipe 2 is arranged in the sewage pipe 1 in the same horizontal direction as the sewage pipe 1, and a plurality of holes 3 are arranged on the lower bottom surface of the high-pressure air pipe 2 toward the bottom of the sewage pipe 1 along the water flow direction. The high-pressure air pipe 2 is filled with high-pressure air, and the high-pressure air impacts the silt at the bottom of the sewage pipe 1 along the plurality of holes 3.

[0036] In the above technical scheme, the present invention arranges a high-pressure air pipe 2 in the municipal drainage sewage pipe 1, and there are small holes 3 at the bottom of the pipe. When silt removal is required, high-pressure air is filled in the high-pressure air pipe 2 to disturb the bottom sediment of the sewage pipe 1 through the bottom holes 3. At the same time, the high-pressure air pipe 2 occupies the flow section of the sewage pipe 1 from the cross section after being inflated. Under the premise of a certain water replenishment flow rate, the flow rate can be increased. In summary, the hydraulic silt removal effect of the pipeline can be improved. The high-pressure air pipe 2 only has holes at the bottom, because the silt only accumulates at the bottom of the sewage pipe 1. The jet at the bottom of the high-pressure air pipe 2 can also offset the weight of the high-pressure air pipe 2 itself through the reaction force, avoiding insufficient buoyancy, and the high-pressure air pipe 2 sinking to the bottom of the sewage pipe 1 to hinder the flow of water. Inspection wells will be set at a certain distance from the sewage pipe 1. The distance of the high-pressure air pipe 2 is generally based on the spacing of the inspection wells, and high-pressure air silt removal is carried out in sections.

[0037] In another technical solution, Figure 3 As shown, the hole 3 is in an inclined state so that the high-pressure gas ejected from the high-pressure gas pipe 2 is inclined and along the direction of the water flow. The inclined angle between the ejected high-pressure gas and the water flow direction is 30° to 60°. The high-pressure gas is ejected obliquely and along the water flow direction, which has the best impact effect on the sludge.

[0038] In another technical solution, Figure 4 As shown, the hole 3 is in a vertical state, and the high-pressure air pipe 2 is fixed with a vertical auxiliary pipe 4 at each hole 3, and its pipe is just connected to the hole 3. The side of the auxiliary pipe 4 facing the water flow direction is also connected with a branch pipe 5, and its pipe is connected with the pipe of the auxiliary pipe 4. The branch pipe 5 is in an inclined state and along the direction of the water flow.

[0039] In the above technical solution, the arrangement of the auxiliary pipe 4 and the branch pipe 5 can make the high-pressure gas ejected from the same hole 3 tilt forward and eject vertically at the same time, which has a stronger disturbance impact on the sludge. In addition, the arrangement of the auxiliary pipe 4 can also play a role in supporting the high-pressure air pipe 2. Even when the jet is not being ejected, it can prevent the high-pressure air pipe 2 from sinking to the bottom of the sewage pipe 1 due to insufficient buoyancy and hindering the flow of water, and it can also prevent sludge from being deposited on the wall of the high-pressure air pipe 2. The lowest point height of the branch pipe 5 is higher than the lowest point height of the auxiliary pipe 4. In addition, the inclination angle of the branch pipe 5 is consistent with the previous embodiment, which is 30° to 60°.

[0040] In another technical solution, an auxiliary block 6 is further provided below the auxiliary pipe 4, and its outer diameter is greater than twice the diameter of the auxiliary pipe 4, and the pipeline of the auxiliary pipe 4 passes through the bottom of the auxiliary block 6; a plurality of disturbance rods 7 are evenly spaced and hingedly connected to the outer side surface of the auxiliary block 6 by hinges, and the disturbance rods 7 are staggered with the branch pipe 5 to ensure that the disturbance rods 7 do not interfere with the ejection of high-pressure gas in the branch pipe 5; the lower end of the disturbance rod 7 is an inclined surface inclined upward toward the auxiliary pipe 4, and the sum of the diameter of the high-pressure gas pipe 2, the height of the auxiliary pipe 4, and the length of the disturbance rod 7 is greater than the diameter of the sewage pipe 1.

[0041] In the above technical solution, the setting of the auxiliary block 6 does not affect the smooth progress of the jet. In addition, the area of ​​the auxiliary block 6 is large, which can better support the high-pressure air pipe 2. The disturbance rod 7 can rotate around the outside of the auxiliary block 6, and multiple disturbance rods 7 are distributed in a circle on the outside of the auxiliary block 6. When the high-pressure air pipe 2 is inflated to move up and down, through the setting of the disturbance rod 7, the lower ends of the multiple disturbance rods 7 can be close to or away from the auxiliary block 6, so as to further disturb the sludge and speed up the dredging process. When the high-pressure air pipe 2 moves to the top of the sewage pipe 1, the disturbance rod 7 is also in an outward tilted state, ensuring that when the high-pressure air pipe 2 moves downward, the disturbance rod 7 can also be opened outward to the sludge to disturb the sludge.

[0042] In another technical solution, the pressure of the high-pressure air pipe 2 is adjustable. According to the silt flushing effect, the high-pressure airflow ejected from the hole 3 in the high-pressure air pipe 2 can blow the deposited silt. Once the silt is moved, it is easier to flow away with the water flow, thereby achieving silt removal.

[0043] In another technical solution, Figure 5 and Figure 6 As shown, the auxiliary pipe is also provided with a sealing cleaning mechanism, which includes:

[0044] The sealing gasket 8 is formed integrally of a steel gasket 17 and a rubber gasket 18. The steel gasket 17 includes a circle at the center and a rectangle fixed to the outside of the circle and formed integrally with the circle. The rubber gasket 18 wraps the steel gasket 17 therein so that the sealing gasket 8 is a circular structure. The diameter of the circle at the center of the steel gasket 17 is slightly smaller than the pipe diameter of the auxiliary pipe, and the diameter of the rubber gasket 18 is slightly larger than the pipe diameter of the auxiliary pipe. The sealing gasket 8 is hinged in the pipe of the auxiliary pipe through the rectangular end of the steel gasket 17 and is in a horizontal state. The hinge of the sealing gasket 8 is symmetrically arranged on both sides of the pipe of the auxiliary pipe in the horizontal direction with the branch pipe, and the sealing gasket 8 is located above the branch pipe;

[0045] A push rod 9, the spacing of which is located just below the sealing gasket 8, one end of the push rod 9 is located inside the auxiliary pipe, and the other end horizontally passes through the auxiliary pipe from below the hinge of the sealing gasket 8. The part of the push rod 9 located on the auxiliary pipe wall has a push block 10 protruding downward, which is arranged close to the inner wall of the auxiliary pipe. The auxiliary pipe wall has a downwardly concave groove below the push rod 9, in which a horizontal spring and a push block 10 are arranged. One end of the spring is fixedly connected to the push block 10, and the other end is fixed to the groove wall away from the inner wall of the auxiliary pipe.

[0046] A fixing rod 11, which is fixed on the outer side wall of the auxiliary tube and is horizontally located just above the push rod 9;

[0047] A positioning rod 12, which is fixed on the outer side wall of the auxiliary tube and horizontally located directly below the push rod 9, and the upper surface of the positioning rod 12 has a downwardly recessed horizontal positioning groove;

[0048] The hinge rod 13 is vertically arranged and its lower end is located in the positioning groove. The upper end of the hinge rod 13 is located at the wall of the high-pressure air pipe above it. An elastic cleaning sheet is fixed to the upper end of the hinge rod 13. The elastic cleaning sheet is in an arc shape matching the wall of the high-pressure air pipe and has a length along the radial direction of the high-pressure air pipe. This length ensures that the cleaning sheets at adjacent holes do not interfere with each other. The hinge rod 13 is connected to the other end of the push rod 9 by an elastic band. The hinge rod 13 is hinged to the outer end of the fixed rod 11;

[0049] A limiting rod 14, which is fixed on the outer side wall of the auxiliary tube and horizontally located just above the fixing rod 11, and the limiting rod 14 has a horizontal passage that passes through from top to bottom, which just allows the hinge rod 13 to pass vertically;

[0050] Among them, when one end of the push rod 9 is completely located in the auxiliary pipe, the upper end of the hinged rod 13 is inclined away from the auxiliary pipe and the hinged rod 13 is located at the outermost side of the horizontal channel of the limiting rod 14 and the innermost side of the positioning groove of the positioning rod 12 from top to bottom.

[0051] In the above technical solution, in order to prevent water or mud in the sludge from entering the pipelines of the auxiliary pipe and the branch pipe, and entering the high-pressure air pipe through the holes, and at the same time, the high-pressure air pipe will deposit a lot of sludge on the pipe wall when it is deposited in the sewage pipe, and the sludge needs to be properly cleaned to prevent the high-pressure air pipe from being too heavy and affecting the dredging effect. Therefore, the sealing and cleaning mechanism of the present invention is set on the auxiliary pipe. The sealing gasket 8 is integrally formed of two parts. The steel gasket 17 is a hard material, and the rubber gasket 18 is a soft material. The steel gasket 17 ensures the complete formability of the sealing gasket 8, and the rubber gasket 18 ensures the sealing. Water and sludge will not enter the high-pressure air pipe under the isolation effect of the sealing gasket 8. The sealing gasket 8 also has another function. When the high-pressure air pipe is filled with high-pressure gas to impact the sludge, the sealing gasket 8 will rotate downward under the strong impact of the high-pressure gas, thereby pushing the push rod 9 to move horizontally outward. In the initial state, the entire device is like Figure 5 As shown, the length of the hinged rod 13 above the hinge of the fixed rod 11 is much greater than the length below, so the push rod 9 only needs to push a small distance to achieve a large distance above the hinged rod 13, so that the cleaning sheet can move a long distance and can scrape out the sludge outside the wall of the high-pressure air pipe. The cleaning sheet is an elastic cleaning sheet, which can adapt to the space compression after the hinged rod 13 is vertical. For example, the elastic cleaning sheet that contacts the wall of the high-pressure air pipe is a hard steel sheet, and the part connected to the hinged rod 13 is also a hard steel sheet, and the middle part is connected and filled with an elastic block with high elasticity. The hinged rod 13 and the fixed rod 11 are not only hinged but also can slide relative to each other, that is, sliding hinged, such as the end of the fixed rod 11 is hinged to a pulley, the hinged rod 13 has a concave slide groove, and the pulley is fitted in the slide groove without disengagement. The horizontal channel of the limit rod 14 is used to limit the upper part of the hinged rod 13 and stabilize its position. When the push rod 9 moves outward, the spring is compressed. When the high-pressure gas stops, the push rod 9 is pushed back to its original state under the rebound force of the spring. At the same time, when the push rod 9 moves into the auxiliary pipe, it can also push the sealing gasket 8 back to its original horizontal state. The whole process does not require manual operation and is completely controlled by high-pressure gas. It is simple, convenient and practical.

[0052] In another technical solution, a limited sealing piece 15 is further provided in the pipeline of the auxiliary pipe, which is annular and horizontally fixed in the pipeline of the auxiliary pipe, and the inner diameter of the limited sealing piece 15 is slightly larger than the diameter of the central circle of the steel gasket 17, and the limited sealing piece 15 is arranged just above the sealing gasket 8. The setting of the limited sealing piece 15 is closely matched with the sealing gasket 8 to achieve better sealing and limit the position of the sealing gasket 8 at the same time.

[0053] In another technical solution, one end of the push rod 9 is in close contact with the inner wall of the auxiliary pipe and is an inclined surface inclined from the end surface to the upper surface. The central circle of the steel gasket 17 is provided with another rectangular steel sheet on the side symmetrical to the rectangle, and a vertical auxiliary rod 16 is fixed below it, and its lower end is just above the inclined surface of the push rod 9. When the sealing gasket 8 rotates downward under the impact of high-pressure gas, the push rod 9 can move outward smoothly through the push of the auxiliary rod 16 and the cooperation of the inclined surface to make way for the high-pressure gas channel.

[0054] In another technical solution, the auxiliary pipe wall has a slide rail above the push rod 9, and a pulley matching the slide rail is correspondingly arranged on the push rod 9. The slide rail and the pulley cooperate to ensure that the push rod 9 can move inward and outward under a relatively small thrust.

[0055] Although the embodiments of the present invention have been disclosed as above, they are not limited to the applications listed in the specification and the implementation modes, and they can be fully applied to various fields suitable for the present invention. For those familiar with the art, additional modifications can be easily implemented. Therefore, without departing from the general concept defined by the claims and the scope of equivalents, the present invention is not limited to the specific details and the illustrations shown and described herein.
