Embodiment Construction

[0021] The specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0022] Such as Figure 1-5 As shown, a preferred embodiment of the present invention, the special sprinkler head for urban underground pipeline dredging has a nozzle seat 1, and the nozzle seat 1 includes a large-angle injection port 11, a water collection tank 12, a water pipe joint 13 and a small-angle injection port 14; The water collecting tank 12 is arranged in a hemispherical shape at one end of the nozzle seat 1, and the water pipe joint 13 is arranged at the other end of the nozzle seat 1, and communicates with the water collecting tank 12. The axis of the nozzle seat 1 is evenly arranged on the outer wall of the nozzle seat 1, and the small-angle injection port 1...

Abstract

The invention relates to the technical field of desilting of underground pipelines, in particular to a spray head special for desilting of an urban underground pipeline. The problems that the flow velocity loss of high-pressure water inside an existing spray head is large, a spraying water column is dispersed after being sprayed into the inner wall of the underground pipeline, spraying strength isinsufficient, and consequently, the cleaning effect is poor are solved. According to the spray head, a flow diversion channel is formed to be annular, the section of the flow diversion channel is semicircular, the flow diversion channel is in smooth transition connection with a water gathering channel, the center of the flow diversion channel is protruded towards the water gathering channel alongthe axis of a balance weight head to form a flow diversion cone head, thus high-pressure water entering through a water pipe joint can be subjected to flow diversion at the flow diversion cone head,the direction of the high-pressure water is smoothly changed through the semicircular flow diversion channel and the water gathering channel in smooth transition connection with the flow diversion channel, the high-pressure water does not acutely collide with the water gathering channel and the flow diversion channel, and the flow velocity loss of the high-pressure water is reduced effectively. The spray head is mainly used for desilting of the urban underground pipeline.

Description

technical field [0001] The invention relates to the technical field of dredging underground pipelines, in particular to a special nozzle for dredging urban underground pipelines. Background technique [0002] Urban underground pipelines refer to the water supply and drainage pipelines buried underground within the city, and are important infrastructure and lifelines to ensure the operation of the city. Due to long-term use, a large amount of silt and other dirt will adhere to the inner wall of the underground pipeline. After scraping the inner wall of the underground pipeline with a spatula, the silt will be scraped off and attached to the inner wall of the underground pipeline. It is necessary to use a high-pressure water nozzle to wash away the silt. Lose. In the existing nozzle, the flow rate of high-pressure water in the nozzle is greatly lost, and the sprayed water column will disperse when it is sprayed on the inner wall of the underground pipeline, and the spraying f...
