Document Type and Number:
WIPO Patent Application WO/2012/002682
Kind Code:
A3
Abstract:
A sub-marine propulsion device using jet principle includes a first body (10), a second body (20), partition walls (30), batteries (40), a sub-marine motor (50), first and second propellers (60, 60a), and fixing body (70). The first body (10) has a first outer body (11) formed in the semicircular shape, a first inner body (13) positioned in the first outer body (11) so as to be fixed with the first outer body (11) at both side ends thereof and having a semicircular first receiving portion (12) formed in the center, and first hinge portions (14) formed at both side ends. The second body (20) has second hinge portions (24) at both side ends so as to be symmetrically coupled with the first hinge portions (14) of the first body (10), a second outer body (21) formed in the semicircular shape, and a second inner body (23) positioned in the second outer body (21) so as to be fixed with the second outer body (21) at both side ends thereof and having a semicircular second receiving portion (22) formed in the center. The partition walls (30) form compartment spaces defined between the first outer body (11) and the first inner body (13), which form the first body (10), and between the second outer body (21) and the second inner body (23), which form the second body (20). The batteries (40) are inserted into the spaces defined by the partition walls (30). The sub-marine motor (50) is electrically connected to the batteries (40) and is received in the first receiving portion (12) of the first body (10) and the second receiving portion (22) of the second body (20). The first and second propellers (60, 60a) are respectively and axially mounted at both sides of the sub-marine motor (50) so as to rotate by the rotation driving force of the sub-marine motor (50). The fixing body (70) is fitted in the first hinge portion (14) of the first body (10) and the second hinge portion (24) of the second body (20) so as to fix the first body (10) and the second body (20), which are symmetrical to each other.
