UST Anchoring Assembly With Screw Tensioning for Holding Straps
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The installation and tightening of underground storage tank (UST) holding straps are inefficient due to challenges with existing anchoring structures, such as deadman anchors, which struggle to securely hold USTs in place.
Innovation Solution
An anchoring assembly comprising a base connectable to the UST's top surface, an anchor reversibly secured to the base, and a tightening mechanism that adjusts the tension of the holding strap by moving the hook component with respect to the UST's surface, using a rotating member and travelling member to modify the strap's tension.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If traditional deadman anchors and straps are used to secure underground storage tanks, then the tank can be anchored in place, but the tightening process becomes difficult and inefficient
Solution Approach 1:
The patent replaces traditional mechanical tightening systems (manual turnbuckles, winches, or hydraulic tensioners) with a screw-based tightening mechanism. The screw thread converts rotational motion into linear displacement, automatically generating high tension forces through mechanical advantage. This substitution eliminates the need for complex external tightening equipment and manual adjustment procedures, making the system both easier to operate and more productive during installation.
2Productivity
If holding straps are used to secure the UST, then the tank can be held in place, but the tension adjustment becomes inefficient
Solution Approach 1:
The patent incorporates a dynamic tension adjustment mechanism where the screw component can be rotated to precisely control the position of the hook assembly relative to the base. This allows the tension in the holding strap to be dynamically adjusted during installation by simply rotating the screw, eliminating time-consuming manual tensioning operations and enabling quick adaptation to different installation requirements.

AI summary
An anchoring assembly and related system and method for facilitating the securing a holding strap to a storage tank and holding of the latter to the ground, comprising a base that is connectable to a top surface of the storage tank and an anchor that is reversibly secured to the base and positionable in a transverse direction of the storage tank to anchor a proximal end of the holding strap. The anchor includes a tightening mechanism being supported above the top surface of the storage tank by the base, wherein the tightening mechanism is actuable to move the anchor with respect to the top surface of the storage tank, thereby modifying a tension of the holding strap.
