Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing sprinkler mechanisms are prone to sand getting stuck on the transmission structure, leading to jamming, wear, and reduced service life.
Innovation Solution
A sand-proof sprinkler mechanism is designed with a housing that includes an impeller transmission member and a transmission device, along with a sealing chamber and water baffle to prevent sand from entering and causing damage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the transmission structure is exposed to water source containing sand, then the sprinkler mechanism can operate and water plants, but sand gets stuck on the transmission structure causing jamming and wear
Solution Approach 1:
The housing is divided into a sealing chamber that houses the transmission device and an external water passage area. The water baffle creates a separate water inlet path for the impeller that does not expose the transmission structure to sand-containing water. This spatial segmentation protects the transmission structure while maintaining operational functionality.
Solution Approach 2:
The water baffle acts as an intermediary element that directs water flow to the impeller through a protected path. It mediates between the external water source and the internal transmission structure, allowing water to reach the impeller while preventing sand from entering the sealing chamber where the transmission device is located.
2Reliability
If a sealing chamber is added to protect the transmission device from sand, then sand-proof protection is achieved, but the device structure becomes more complex
Solution Approach 1:
The housing serves multiple functions: it contains the sealing chamber for the transmission device, provides water passages for the impeller, and incorporates the water baffle for flow direction. The water baffle simultaneously directs water flow and acts as a protective barrier. This multi-functionality reduces the need for additional separate components, thereby limiting the increase in device complexity.
Solution Approach 2:
The sealing chamber, water passages, and water baffle are merged into a single integrated housing structure. The transmission device is mounted within the housing, and the water baffle is incorporated as an integral part of the housing's internal structure. This merging approach protects the transmission device while maintaining a relatively simple overall device structure.
3Reliability
If the impeller transmission member is protected from direct water contact, then sand enters less, but water flow direction control becomes more difficult
Solution Approach 1:
The conversion wheel can rotate to different positions (first rotation position and second rotation position) to dynamically control water flow direction. The blocking piece on the conversion wheel can be positioned to block either the first through hole or the second through hole, allowing flexible adjustment of water flow paths while maintaining protection of the transmission device through the sealing chamber structure.
Solution Approach 2:
The conversion wheel and blocking piece act as intermediaries that control water flow direction without requiring direct exposure of the transmission device to water. The blocking piece selectively blocks different through holes in the conversion wheel, mediating between the water inlet and the impeller transmission member, thereby enabling flow direction control while maintaining the protective sealing chamber structure.

Function Achieved in This Case
The mechanism effectively prevents sand from getting stuck on the transmission device, reducing the risk of jamming and wear, thereby extending the service life and ensuring continuous operation.
Implementation Method 1
A water baffle is provided at an opening of the sealing chamber for covering the sealing chamber
Implementation Method 2
the impeller transmission member is driven by the water flow to rotate clockwise and counterclockwise to drive the hose to rotate back and forth

AI summary
A sand-proof sprinkler mechanism has a base (1). A housing (2) and a connecting platform (10) are provided on the base (1). A hose (3) is rotatably connected between the housing (2) and the connecting platform (10). The housing (2) has a water outlet (21), a housing inner chamber (22) and a water inlet (23) that are in communication with the hose (3). The housing (2) includes an impeller transmission member (24) and a transmission device (25) that is drivingly connected to the impeller transmission member (24) and the hose (3). The housing (2) further includes an adjustment device (4) for adjusting a direction of a water flow, so that the impeller transmission member (24) is driven by the water flow to rotate clockwise and counterclockwise to drive the hose (3) to rotate back and forth. The housing (2) further has a sealing chamber (221) for mounting the transmission device (25). A water baffle (261) is provided at an opening of the sealing chamber (221) for covering the sealing chamber (221). The water baffle (261) has a connecting through hole (2611) for the transmission device (25) to be connected to an output end of the impeller transmission member (24). The above structure prevents particles from entering and getting stuck.
