Abstract

Page 25 of 47 7. ABSTRACT The Fluid Dynamics Based Solar Tracking System is developed for floating solar. As it incorporates dynamic fluid-structure interactions, its model for structural analysis is closer to the real working conditions of the structures on the body of water. As a result, the structures are designed to be simpler and lighter, leading to saving cost of materials and installation while maintaining structural stability. This invention mainly focuses on structural components and related methods of the proposed Fluid Dynamics Based Solar Tracking System. These are defined, described, specified and demonstrated with respect to the concept of dynamic fluid-structure interaction. In addition to a number of methods added such as damping systems, the destructive limit of the geometrical variable structure is also established and presented for structural designs.

Description

TITLE: SYSTEM OF HANGING LIQUID DAMPING TANK FOR FLOATING SOLAR TRACKING SYSTEMS FIELD
[0001] It is related to the fields of:
(1) Structural Engineering
DESCRIPTION
1.1 System of Hanging Liquid Damping Tank (SHLDT) (Figure 1)
[0002] Hanging Liquid Damping Tank (HLDT) (#9) is a tank partially filled with water. It
is hung either from a Torsional Beam (#12) or from a top of a Structural Floating Post
(SFP) (#11). The Torsional Beam is a part of a floating solar tracking system which can
rotate an Array of Solar Panels (#13). The SFP is the primary structure which bear
upper structures supporting the Array of Solar Panels. The SFP is either floated by a
Float (#10) which can be either concentrated at the bottom or distributed along the
body of the SFP.
[0003] The HLDT is a liquid damper which prevent the SFP from being oscillated by
waves. In addition, if it is hung from a Torsional Beam, it is also a damper eliminating
twisting moments for rotations of the Torsional Beam . The reason is that, it helps to
eliminate a portion of twisting moments caused by decentralized weights of upper
structures and the Array of Solar Panels as the weight of the HLDT creates opposite
twisting moments.
[0004] A System of Hanging Liquid Damping Tank (SHLDT) is composed of multiple
Hanging Liquid DampingTank (HLDT)s distributed alonga floatingArrayof Solar Panels
with or without a solar tracking system integrated.
