BR-102024017613-A2 - IMPROVEMENT IN MODULAR RESERVOIR

Abstract

A modular cubic reservoir (10) is described, having a front face with a concave outer profile (101), a rear face with a convex outer profile (102), and side faces (103) with an outer surface having at least one raised area (1031). A metal structure comprising a base (20) fixed to the stationary or mobile chassis (C) by bolting is fitted into said reservoir (10). Orthogonal crossbars (21) project from the base (20) in a substantially vertical position and juxtaposed to the side faces (103) of the reservoir (10), and curved crossbars (22) are positioned juxtaposed to the concave front face (101) of the reservoir (10), providing a resistant structure to withstand the impact of waves generated by the movement of the stored liquid.

Description

FIELD OF THE INVENTION [01] The present invention patent describes a modular reservoir that has a metal structure that surrounds three faces of the reservoir where the impact of the waves generated by the movement of the stored liquid is greatest, the metal structure being fitted into the reservoir and fixed to a stationary or mobile chassis by bolting. BACKGROUND OF THE INVENTION [02] Storage tanks for transporting liquids in trucks, airplanes, spacecraft, and ships can, under certain circumstances, be subject to high-amplitude harmonic loads, potentially reaching resonance modes. When reflected off the compartment walls, these waves impose hydrodynamic forces that can generate a destabilizing effect. This interaction between the fluid and the structure can cause container rupture, instability, and loss of maneuverability in vehicles transporting liquid substances. [03] When the truck moves, the transported liquid moves in the opposite direction. This movement, called slosh, is enhanced when the tank is partially loaded, with more weight being transferred to the sides of the tank during turns, which can make tipping easier. [04] Larger volumetric capacity tanks generally have wave-breaking devices, which reduce load movement, especially during braking and acceleration, and also on inclines/declines, as per document PI0902518. [05] One of the solutions conventionally used is the 80/20 rule. According to this rule, above 80% of the reservoir is full, the mass of the liquid is large and the space for movement is small. Below 20% of the reservoir's volumetric filling, the space for liquid movement is large, but the mass of liquid is small enough to affect stability. Therefore, in the intermediate range (between 20% and 80%), the volume of liquid is large and the space for lateral displacement is also large, allowing for additional weight transfer between the sides of the tank during turns and maneuvers. And this factor is decisive in causing the vehicle to roll over. [06] The state of the art describes modular reservoirs which, among their advantages, reduce the volume of liquid per module and, therefore, it is possible to manage fluid movement more effectively. [07] Document PI1003564 describes a multi-reservoir system for transporting and storing liquids, featuring a metal frame comprising a cradle connected to arms that attach to the chassis. [08] Document BR202020023901 describes rotomolded tanks manufactured in a modular fashion and fitted together, arranged on a metal chassis. [09] The state-of-the-art solutions related to modular tanks, although they describe frames for attaching the tank to the chassis, either consist of fixed structures for linking the tank to the chassis, such as arms arranged on the chassis beam, or consist of metal plates that receive the tank from above, which makes the attachment less resistant to fluid movement. [010] Thus, the Applicant has developed an improvement in modular reservoirs that features a metal structure that surrounds three faces of the reservoir, precisely on the faces where the impact of waves generated by the movement of the stored liquid is most pronounced. The metal structure is attached to the reservoir by fitting, without any interference with the surface of said reservoir, and is fixed to a stationary or mobile chassis. BRIEF DESCRIPTION OF THE FIGURES [011] Figure 1 shows a perspective view of several reservoirs connected by a metal structure.

[014] Figure 4 shows a detailed representation of the association of adjacent modules. [015] Figure 5 shows a detailed view of how the metal structure is attached to the chassis structure. DETAILED DESCRIPTION OF THE INVENTION [016] The improvement in modular reservoir, object of the present invention, comprises a polymeric reservoir of cubic shape (10) provided with an upper opening (11) and a lower support with a linear channel (12) where a pipe (T) is installed for draining the contents of the reservoir by means of control by a valve (not shown). [017] The reservoir (10) has a front face with a concave outer profile (101) and a rear face with a convex outer profile (102). The side faces (103) have at least one raised area (1031) on their outer surface. [018] A metal structure comprising a base (20) fixed to the stationary or mobile chassis (C) by bolting is fitted into the reservoir (10), and the reservoir is positioned on said base (20), as shown in figure 5. From the base (20) orthogonal crossbars extend onto the surface of the reservoir (10), with orthogonal crossbars (21) in a substantially vertical position and juxtaposed to the lateral faces (103) of the reservoir (10) and curved crossbars (22) that are positioned juxtaposed to the front face of concave profile (101) of the reservoir (10).
