Nozzle for urban viaduct guardrail

Abstract

The invention discloses a spray nozzle for an urban viaduct guard bar. A spray hole protective device comprises a protective cover, connecting shafts, gears, racks, a piston and a spring. The protective cover includes half barrels; grooves are formed in the upper edges of the half barrels; the connecting shafts are rotationally connected to the barrel wall of a spray nozzle body in an inserting mode; one ends of the connecting shafts are fixedly connected with the gears located in the spray nozzle body; the other ends of the connecting shafts are fixedly connected with the upper portion of the protective cover; the piston is arranged inside the spray nozzle body in a sliding mode; one end of the spring is fixedly connected with the bottom of the spray nozzle body; the other end of the spring is fixedly connected to the lower side surface of the piston; one ends of the racks are fixed to the upper side surface of the piston; the racks are engaged with the gears; and when the spring is compressed to a certain degree, the piston is located below spray holes. The spray nozzle is suitable for being mounted on a viaduct for usage, the road surface spraying effect is guaranteed, and the spray holes can be prevented from being blocked by lime, sand grains and the like.

Description

technical field [0001] The invention relates to a nozzle for urban viaduct guardrails. Background technique [0002] my country's water resources are scarce, so more and more cities are building sponge cities, that is, when it rains, they can absorb, store, infiltrate, and purify water on the spot, and "release" the stored water and use it when needed. The current rainwater storage technology has been perfected, but the problem of how to effectively recycle the stored rainwater has not yet been solved. In particular, there are many viaducts in the urban areas of our country, and a large amount of rainwater will be collected when it rains. The conventional method is to use this part of rainwater to irrigate the vegetation below the viaducts, but this method has a low utilization rate of rainwater. However, when the temperature is high in summer, the road surface of the viaduct often needs artificial watering to cool down, so if the rainwater collected from the viaduct surfac...

AI Technical Summary

Problems solved by technology

However, traditional duckbill or rotary nozzles cannot achieve a good spraying effect, and there are many lime and sand particles on the viaduct deck, which are easy to block the nozzles. Therefore, it is imminent to design a nozzle for urban viaduct guardrails.
