Safety device for protecting pipeline from foreign matters

Abstract

The invention discloses a safety device for protecting a pipeline from foreign matters. An inverted L shaped part is arranged in the periphery of an opening in the upper end of a circular pipe body, and a plurality of first positioning cylinders are arranged on the inner wall of the circular pipe body; an inverted L shaped component is arranged in the circular pipe bodies, and a plurality of pin holes are formed in two walls of the upper ends of the inverted L shaped component; a pin rod is arranged in each corresponding pin hole; a plurality of inverted triangular valves are arranged in the inverted L shaped component, and strip-shaped holes are formed in two sides of the upper end of each corresponding inverted triangular valve; the pin rods pass through the corresponding strip-shaped holes to fix the inverted triangular valves into the inverted L shaped component; a second positioning cylinder is arranged on the rear surface of each corresponding inverted triangular valve and is connected with the corresponding first positioning cylinder through a compressing spring. The device has the characteristics of being simple in structure, easy to produce, and convenient to operate. With the adoption of the device, pipelines in an enterprise and a public place can be prevented from being invaded by the foreign matters and pollutants, and thus the safety of the pipelines can be ensured.

Description

technical field [0001] The invention relates to pipelines and pipeline safety protection facilities, in particular to a pipeline anti-foreign matter safety device. Background technique [0002] In the production of enterprises and external public facilities, a large number of pipe networks are arranged according to the needs, including underground pipes and pipes or drainage facilities. Due to the smooth flow of pipes, unimpeded water flow is a big rule, but these traditional methods also have defects. Because many pipe openings are exposed to the open air, various pipes and pipelines are susceptible to interference and invasion by foreign matter, especially the backflow of pollutants or the flow of some living organisms, which brings safety hazards to the production of enterprises and people's lives. to hidden dangers. In real life, some unsafe accidents that occur as a result are not uncommon. Contents of the invention [0003] The object of the present invention is to...
