Wave Generator and Tsunami Defence System Lesson

<p>This wave generator tank was one I designed to use for a unit of work on plate tectonics, and the disasters that occur as a result of plate movements. I designed it to work with existing resources we had in the school. A laser cutter was used to cut the clear acrylic panels for the tank, this acrylic was 3mm thick. The Lego EV3 system was used as the drive system</p> <p>Students were tasked with designing barriers to mitigate the effect of a tsunami on coastal communities. The basic principle is that cam and plunger pushes the water over the internal wall and the water collects in a container. The more water that collects, the less effective the barrier</p> <p><a href="https://youtu.be/N2fm3ogYWmg">https://youtu.be/N2fm3ogYWmg</a> - Visual method for conducting the task for students</p> <p><a href="https://youtu.be/1xv4zZEnB0M">https://youtu.be/1xv4zZEnB0M</a> - brief video of the wave tank and a barrier in action</p> <h3>Print Settings</h3> <p><strong>Printer Brand:</strong></p> <p>Dremel Digilab</p> <p class="detail-setting printer"><strong>Printer: </strong> <div><p>3D45</p></div> <p><strong>Rafts:</strong></p> <p>No</p> <p class="detail-setting supports"><strong>Supports: </strong> <div><p>Doesn't Matter</p></div> <p><strong>Resolution:</strong></p> <p>Doesn't matter but I used 0.28</p> <p class="detail-setting infill"><strong>Infill: </strong> <div><p>I used 10% Gyroid</p></div> <p><strong>Filament:</strong> Dremel PLA Post-Printing =============</p> <p>The components for the box are a tight fit and need to be gently knocked together using a rubber mallet and bonded with acrylic glue</p> <p>3mm x 4.5mm heat set inserts were used in two holes in the internal walls. 12-15 mm M3 bolts were used to secure the backing plate to the internal wall</p> <p>M4 x 40mm bolts were used as the pins in the backing plate and secured in place with nuts</p> <p>M3 x 12mm bolts were used with nyloc nuts to secure the plunger mount and the cam wheel to the cam arm</p> <p>Acrylic glue was used to secure the plunger mount to the plunger and the motor mount to the tank, the lego motor was held in place as the motor mount was attached to the tank.</p> <p>for added water tightness I used silicon on all the joints in the tank and I also taped the external edges of the tank</p> </p></p></p> Category: Engineering
