Problems solved by technology

In addition to posing a great threat to the life safety of underwater creatures and divers, exposed propellers are also affected by other factors, such as when ordinary ships are sailing, the propellers are hinged to hard objects or entangled by ribbons, etc. etc. will cause damage to the propeller and cause the ship to be unable to sail normally

Embodiment Construction

[0016] The ship's underwater power device includes a propeller 1, a transmission shaft 2, a protective casing 3, a transmission rod 4 and a turbine assembly 5, and a transmission shaft 2 is housed in the protective casing 3, and a plurality of propellers 1 are installed at intervals on the transmission shaft 2. The rear end of the shaft 2 is provided with a transmission rod 4, one end of the transmission rod 4 extends above the protective casing 3 and is connected with the power equipment, the other end of the transmission rod 4 and the transmission shaft 2 are connected to each other through the turbine assembly 5, thus Drive the transmission shaft 2 to rotate during work, and then drive the propeller 1 to rotate.

[0017] The protective housing 3 of the marine underwater power unit is a cylindrical body, and a filter cover 6 is installed on the front port of the protective housing 3 to prevent foreign matter in the water from entering to form winding on the propeller 1 or dam...

Abstract

The invention relates to a power device, in particular to a ship underwater power device. The ship underwater power device includes propellers, a transmission shaft , a protection housing, a transmission rod, and a turbine assembly; the transmission shaft is arranged in the protection housing; a plurality of propellers are arranged on the transmission shaft at intervals; the transmission rod is arranged on the back end of the transmission shaft; and one end of the transmission rod extends above the protection housing, and the other end of the transmission rod is connected to the transmission shaft through the turbine assembly. The propellers are arranged in the protection housing, and then the problem that the conventional propellers are directly exposed outside can be solved, and damage to life entities due to exposed propellers can be effectively avoided; and a filtering screen arranged on a front opening of the protection housing can effectively prevent damage to the propellers due to foreign matters, and the service life of the propellers can be prolonged. The ship underwater power device is specially used in ships and boats.

Description

technical field [0001] The invention relates to a power device, in particular to a marine underwater power device. Background technique [0002] With the increase of human ocean exploration and research activities, the accidents of boat propellers harming aquatic organisms and humans are increasing. According to the U.S. West Coast Guard, from 2005 to 2013, accidents between boat propellers and divers caused 636 diver injuries and 38 diver deaths. The 442 injured and 29 killed were due to direct impact with the propeller. It can be seen from this that this is only the statistics of ship propeller injury accidents in local waters in the United States in the short term, and this data will increase greatly in the world. In addition to posing a great threat to the life safety of underwater creatures and divers, exposed propellers are also affected by other factors, such as when ordinary ships are sailing, the propellers are hinged to hard objects or entangled by ribbons, etc. ...
