Definitions
- the space used by the metallic structure that protects the electronics consumed a lot of system space, preventing it from being applied to smaller section ducts, such as those of 4 inches used in the Oil and Gas industry, for example.
- the number and types of connections between the robot modules were limited to the commercial connectors available. These in turn have little variety and are also bulky, taking up a lot of space in the modules.
- US6434317 discloses a pressure vessel to house electronic components in an underwater environment and to allow the connection of the components to signal transmission elements of a signal cable.
- US2002064367 discloses a pressure vessel in cylindrical shape capable of withstanding high hydrostatic pressures and also withstanding high temperatures, demonstrating the ability to isolate the passage of wires and essential connections in the transmission of data by optical fiber.
- Document W02001013692 discloses a pressure vessel for passive conduction of heat generated by electronic components inside.
- the present invention is used to compose the structure of a system that operates inside ducts. It can be used in a robotic system in the form of a train to move tools through tubes or ducts with reduced diameters. It avoids the need for high-cost commercial connectors with limited range of connections.
- the proposed solution is to partition / divide the electronic or hydraulic components into pressure vessel modules and, thus, making it necessary to provide an adequate means of interconnection between the modules by means of an elastomeric conduit. Each module has a heat exchanger system (heatsink) to remove the heat generated by the electronic equipment installed inside.
- the product of the invention has a sufficient degree of freedom to move around underwater pipelines and pipes, where the hydrostatic pressure is extremely high.
- FIG. 1 shows a representative side view of the integrated modules without hoses
- FIG. 3 shows a side view of the rubber injection mold prepared for processing
- FIG. 4 shows a section of the vessel lid showing the resin stopper
- FIG. 6 shows a side section of the module with an electronic plate mounted on the heat sink
- FIG. 7 shows a front section of the module with an electronic board mounted on the heat sink.
- the invention allows any type of conductor to be placed in the connection between the modules (1), and that these enter the pressure vessels without the need for exclusive connections for this. This is done by making an elastomeric conduit, called a penetrator (2). In a rubber injection mold (12), where the pressure vessel caps (3) are placed as inserts, it is possible to obtain an ideal adhesion between the cover material (3) and the penetrator elastomer (2).
- the covers are prepared with the wires / cables (18) that pass through conical holes (14) in the covers (3), where they are partially filled by a polymeric resin that produces thus a stopper (9) resistant to the pressure of the injection process and, later, to the external pressure, that is, in the application environment of the robot.
- a stopper (9) resistant to the pressure of the injection process and, later, to the external pressure, that is, in the application environment of the robot.
- the invention takes advantage of one of the components of the cylindrical part of the pressure vessel of composite material (5), an internal part to the laminate called Liner (4), normally used only as an auxiliary in the filament winding process to perform the passage of hoses inside the pressure vessel wall. This is done by manufacturing this liner (4), which is made of metallic material, by the process of wire erosion, where the inner section of it is cut with the geometry of channels (15) that are subsequently drilled in order to allow the passage hoses. These channels (15) are dimensioned in order to resist external pressures, because between the hoses and the cavity the pressure of the environment acts.
- the invention uses the technology of heat pipes (6) to direct the flow of this thermal load to the lids of the vessel (3) in metallic material. This is the same cover where we have the conical hole (14) for the conductors to pass through the penetrator (2) and aligned holes (16) for the hoses to pass through the liner (4). Using these components also known as heatpipes, the size of the heatsink plates (13) is conditioned only to the diameter and length of the cavity.
- the module (1) is shown with the lids of the vessel (3).
- the vessel lids (3) connected to the penetrator (2) with the wires / cables (18) coming out of it through the lids (3).
- the vulcanization of rubber purposely uses the caps (3) in the injection mold (12), procedure illustrated in figure 3, to seal the mold (12) and create the ideal adhesion between rubber and metal . This adhesion is extremely important to guarantee the integrity of the invention, which must withstand the efforts of the internal pressure and flexion of the penetrator (2).
- wires / cables (18) are selected and cut with excess length for insertion in the lids of the vessel (3).
- the wires / cables (18) are inserted into the conical hole (14) of the lid (3), a liquid resin is prepared in a Becker and then, by pouring, a resin stopper (9) is formed in a fraction the height of the conical hole (14) (A process similar to that of “Casting”). After curing, the process is repeated for the next cap and inserted into the mold as shown in figure 3.
- a solid material bar which may be of metal or polymer, is produced in the outer diameter of the liner (4) and length such that several vessels can be made in the same filament winding process. Then, a filament winding equipment deposits the composite material continuously in a pre-determined sequence of inaction on the liner (4) until the desired number of layers is reached. Depending on the composite material, post curing is carried out in an oven for a few hours. With the aid of a tome, the bar wrapped with composite material is cut into sections with the exact length of the vessel body (11). The massive section of the liner of these segments is then machined or cut, depending on the material to create the internal cavity. In case the liner (4) is metallic, the wire erosion process is used.
- the lids of the vessel (3) interface with the liner (4) on one side and with the penetrator (2) on the other side.
- holes in these are aligned with the channels (15) of the liner (4) to allow hoses and / or cables to pass between the modules without having to enter the vessel.
- o-ring seals (10) preventing pressure from entering the interior.
- the other end of the heat pipes (6) is coupled to a dissipating plate (13) which in turn is coupled to the part of the electronic component (17) that needs to dissipate heat.
- This heatsink plate (13) uses parallel guides (19) carved on the inner side of the liner (4) for fixation.
- the protection module for embedded electronics is nothing more than a liner (4) in a cylindrical shape adapted to receive electronic components (17), provided with channels (15), also provided with a layer external to the liner (4) forming a cylinder of composite material (5), further provided with two vessel lids (3), further provided with at least one stopper (9), further provided with at least one penetrator (2) and seals (7) to ensure the tightness of the module (1)
