Embedded Sprinkler Head Nozzle Adjustment and Removal Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing sprinkler systems face challenges in adjusting the initial angle of the nozzle without misalignment and in easily removing and replacing the nozzle, as they often require complex and minute processes that can lead to damage during adjustments.
Innovation Solution
A sprinkler head design featuring a base with an axial column, upper and lower toothed rings, a gear column, and flexible adjusting sheets that allow for adjustable oscillation angles and easy nozzle removal through a gap in the receiving chamber, preventing damage during adjustments.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the adjusting shaft is forced rotated after the gear disk reaching a stop, then the elastic cross sheet will slip and engage again to prevent damage, but the angular indicating disk will still be rotated causing misalignment between angular indication and actual nozzle position
Solution Approach 1:
A new angular indicating disk is introduced as an intermediary element that is directly coupled to the gear disk through a coupling structure. This ensures that the angular indication always reflects the actual position of the gear disk, even during slippage events, by eliminating the relative rotation between the indicating disk and the gear disk.
Solution Approach 2:
The coupling structure is designed with elastic teeth that can independently engage and disengage, allowing the angular indicating disk to remain stationary relative to the gear disk during slippage, while the gear disk itself can slip relative to the fixed adjusting sheet.
2Strength
If the nozzle is fixed to the receiving chambers by bolts with total fit, then the connection is secure, but the removal of the nozzle becomes very difficult
Solution Approach 1:
The connection structure transitions from a static total-fit design to a dynamic extraction design where the nozzle can be easily extracted through the gap in the receiving chamber wall, allowing for simple installation and removal operations.
Solution Approach 2:
The nozzle is designed to be extractable through the gap in the receiving chamber wall, allowing for easy removal and replacement without requiring bolt loosening or complex disassembly procedures.
3Ease of operation
If a protruded ear is formed to the center bottom of the nozzle for removal, then the nozzle can be pried out, but the removal is impeded by an inclination obstacle
Solution Approach 1:
The nozzle removal structure is changed from a protruded ear requiring prying action to a gap-based extraction design where the nozzle can be directly pulled out through the gap in the receiving chamber wall, eliminating the inclination obstacle interference.
4Adaptability or versatility
If the sprinkler head is pulled out of the outer tube to modify the initial position of the nozzle, then the position can be adjusted, but the process becomes minute and complicated requiring tightening an upper cover to confine the sprinkler head
Solution Approach 1:
The initial position of the nozzle is made adjustable through the flexible adjusting sheet mechanism, allowing for easy modification of the oscillation angle without requiring the complex process of removing and repositioning the entire sprinkler head.
Solution Approach 2:
The oscillation angle parameter is adjusted by changing the included angle of the flexible adjusting sheet and fixed adjusting sheet, allowing for continuous adjustment of the nozzle's initial position without mechanical repositioning.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables precise adjustment of the nozzle's angle and easy removal and replacement, preventing misalignment and damage, while simplifying the process of modifying the sprinkler's oscillation.
Implementation Method 1
an elastic cross sheet arranged to a bottom end of the adjusting shaft. The cross sheet is engaged with a cross recess formed to an upper end of a linking shaft. While the adjusting shaft is forced rotated after the gear disk reaching a stop, the elastic cross sheet engaged with the cross recess will slip and engage again so as to prevent damage.
Implementation Method 2
a flexible adjusting sheet extending from a lower end of the toothed ring; wherein the lower toothed ring will be indirectly driven by the upper toothed ring; an oscillation angle of the base will be set by changing an included angle of the fixed adjusting sheet and the flexible adjusting sheet.

AI summary
A sprinkler head for an embedded sprinkler includes a base having a adjust device arranged to an upper portion thereof and an inlet pipe formed to a lower portion thereof. The inlet pipe has a lateral outlet and a receiving chamber. A nozzle is received to the receiving chamber. A gap is formed between the nozzle and the receiving chamber so as the nozzle can be easily removed. A lower toothed ring indirectly rotated by the adjust device is arranged to a bottom of the inlet pipe. Angle between a flexible adjusting sheet extending from the lower toothed ring and a fixed adjusting sheet extending from a bottom of the base can be changed. A sleeve is arranged to the inlet pipe to receive an axial tube of a sprinkler so as to oscillate clockwise and counterclockwise with a driving shaft of the sprinkler.
