Borehole Termination Lid With Segmented Plates
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing borehole termination devices fail to effectively cover the borehole outlet, allowing coarse impurities to enter and are either complex, expensive, or difficult to handle and install, especially when transitioning between open and closed states for water extraction.
Innovation Solution
A device comprising two overlapping circular plates with radial notches, allowing for continuous coverage of the borehole edge, with detachable connections for cabling and water pipes, and a suspension element for the pump, enabling easy assembly and maintenance without disconnection of piping or cables.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a mounting clamp is used to suspend the pump, then the pump can be suspended and water can be extracted, but the borehole outlet cannot be covered to prevent coarse impurities from entering
Solution Approach 1:
The lid is divided into two detachable plates that can be separated. The first plate remains fixed on the borehole outlet to provide continuous coverage and prevent impurity entry, while the second plate is removed to allow access for pump suspension and water extraction operations.
Solution Approach 2:
The lid transitions from a static closed state (both plates attached) to a dynamic open state (second plate removed). This allows the system to adapt between providing continuous protection and enabling operational access, resolving the contradiction between prevention and operation.
2Object-affected harmful factors
If a separate bracket is used to hold the mounting clamp over the borehole casing, then the borehole outlet can be covered with a separate cover, but the bracket is expensive and requires specific wall conditions
Solution Approach 1:
The cover function and mounting function are merged into a single integrated lid assembly. The first plate serves both as the protective cover and as the mounting base for the second plate, eliminating the need for a separate bracket structure and reducing overall device complexity and cost.
Solution Approach 2:
The first plate performs multiple functions: it acts as a protective cover to prevent impurity entry, provides a mounting surface for the second plate, and serves as a structural support element. This multi-functionality eliminates the need for additional specialized components like brackets.
3Reliability
If a robust borehole head with hermetic sealing is used, then the borehole is hermetically sealed, but the device is complex and expensive with difficult installation and handling
Solution Approach 1:
The lid is segmented into two detachable plates instead of being a single robust hermetic structure. This segmentation reduces complexity while maintaining the essential function of covering the borehole outlet and providing mounting capability.
Solution Approach 2:
The two-plate lid design uses simpler, less expensive materials and construction methods compared to robust hermetic borehole heads. The plates can be easily manufactured and replaced if needed, reducing overall system cost and complexity while maintaining adequate functionality.

AI summary
The invention relates to a device for borehole termination, which comprises the lid (1) with a passage (15a) for cabling (8) and a passage (15) for a water pipe (7), wherein the lid (1) is on its underside provided with a suspension element (3) for suspending a pumping device. The lid (1) comprises a first plate (1a), which is larger than the outer dimension of the borehole to be terminated and which is provided with a radial notch (13), which extends from the edge of the first plate (1a) towards the central area of the first plate (1a), wherein the lid (1) further comprises a second plate (1b), which is shaped and dimensioned to overlap the radial notch (13) in the first plate (1a) in the area from the outer circumference of the first plate (1a) towards the central area of the first plate (1a), wherein in the central area of the first plate (1a) the second plate (1b) is terminated at a distance from the end of the radial notch (13), so that between the front edge of the second plate (1b) and the inner end of the radial notch (13), there is a passage (15a) for cabling (8) and a passage (15) for the water pipe (7), wherein the two plates (1a, 1b) are detachably connected.
