This past week has been a very eventful one for us. First and foremost, we finally obtained not only the motors that we are going to use for our submersible, but we also bought the PVC that is going to be used towards construction as well. We decided to stick with the 1/2" PVC that Sea Perch includes in the kit. During our lab section, we tested out the motors in a sink to get a good idea of just how powerful the motors we bought were and the results were satisfying. We then went ahead to actually start cutting up the PVC into parts that would be used to build the submersible and went ahead to build the chassis of the submersible. During the lab, we also brainstormed how we would attach the motors to the chassis and decided it would be best to use some sort of bracket made of sheet metal to attach the motors to the corners of our chassis. We started cutting up and bending the sheet metal into the desired shape that we wanted during our mid-week meet up.
This is a video of one of the bilge pumps that we are using as motors on our submersible. We tested it in a sink in lab this week. We are very pleased with the strength of the pump. It pumps at a rate of 350 gallons per hour.
Submersible chassis with four motors in their approximate location. Chassis is made of 1/2" PVC. The motors are the same bilge pumps demonstrated in the video above.
