Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Please refer to fig. 1 to 3, a small cleaning nozzle for cleaning a trenchless pipeline, comprising a base 1 and a cover 2 hermetically connected to the base 1, wherein the base 1 is provided with a water pipe connecting hole 11, the base 1 is further provided with water outlet holes 12 arranged around the water pipe connecting hole 11, the cover 2 is internally provided with an inner cavity 21 communicated with the water pipe connecting hole 11, the cavity diameter of the inner cavity 21 decreases progressively from bottom to top, the upper end surface of the inner cavity 21 is provided with a downward convex bulge 22, and the upper end of the inner cavity 21 is provided with a concave arc-shaped connecting surface 23 located at the periphery of the bulge 22.
In addition, the convex portion 22 has a drop-shaped convex structure.
In addition, the water outlet holes 12 are evenly distributed along the circle of the center of the water pipe connecting hole 11.
In addition, the water outlet 12 is inclined to the axial direction.
In addition, the lid 2 is screwed to the base 1.
The small cleaning spray head for cleaning the trenchless pipeline has the following specific working principle: the water inlet pipe is connected into the water pipe connecting hole 11, the small cleaning nozzle extends into the pipeline, high-pressure water enters the inner cavity 21 and is sprayed out of the water outlet hole 12 after the inner cavity 21 is filled with the high-pressure water, and the high-pressure water can clean the inside of the pipeline from the water outlet hole 12 and can push the small cleaning nozzle to move forward along the inner wall of the pipeline through water pressure, so that the small cleaning nozzle has a good cleaning effect.
Compared with the prior art, the small cleaning nozzle for cleaning the trenchless pipeline can effectively clean the pipeline with small diameter, and has the advantages of good cleaning effect, simple structure, safety and reliability.
The above description is only an embodiment of the present invention, and not intended to limit the scope of the present invention, and all modifications of equivalent structures and equivalent processes, which are made by the present specification, or directly or indirectly applied to other related technical fields, are included in the scope of the present invention.
