AI Technical Summary

Problems solved by technology

[0007] The existing propellers have poor ability to change direction. When the ship needs to turn, the rudder or the direction-changing impeller can be used to make the ship turn through the deflection of the water flow, but it takes a long time and a lot of space to adjust
The thrust of the existing propeller will be reduced when the draft of the ship is shallow, and it cannot maintain strong power
The propeller and the reversing impeller are prone to failure, and it is very inconvenient to go to the dry dock for maintenance at this time

Embodiment Construction

[0023] Below in conjunction with accompanying drawing in the embodiment of the present invention, refer to figure 1 , 1-input shaft I, 2-second input shaft II, 3-diffuser, 4-second output shaft II, 5-output shaft I, 6-propeller or propeller, 7-driving device. 8-Reducer I, 9-Second Reducer II, 10-Guide port, 11-Baffle plate, 12-Protection net, 12-1 Parallel deflection fence blades. 13 - main housing.

[0024] A bottom-drive ship propeller bottom-drive azimuth propeller, the input shaft 1 drives the propeller 6 to rotate through the power generated by the drive device 7 through the reducer I8, and the water is sucked in from the diversion port and discharged from the propeller. When in use, the power unit 7 drives the transmission shaft I1 to rotate through the reduction box I8, and the transmission shaft I1 drives the propeller 6 to rotate, thereby generating thrust. When it is necessary to turn, the 3 guide tubes are rotated according to the direction and angle to be turned,...

Abstract

The invention discloses a bottom-driven multidirectional propeller which comprises a main shell, a reduction box, a gearbox, a transmission shaft, a screw propeller and a reverser. The reduction box is fixedly arranged above the main shell, a driving shaft coming out of the gearbox is connected with the transmission shaft, the transmission shaft is positioned in the inner middle of the main shell, the screw propeller is mounted at the end of the transmission shaft, the lower portion of the main shell is connected with the reverser, the reverser is a rotary guide cylinder, a guide opening is formed in the wall of the guide cylinder, the end of the transmission shaft is also arranged in the guide cylinder, the screw propeller of the transmission shaft and the guide cylinder coaxially rotate in a non-interference manner, the fluid supply direction of the screw propeller is decided by the position of the guide opening when the guide cylinder rotates, and maximum rotating thrust of the screw propeller is obtained in the direction.

Description

technical field [0001] The invention relates to the technical field of ships, in particular to a bottom-drive multi-directional propeller. Background technique [0002] At present, the propellers of propellers on the market are generally directly acting on water or air to achieve direct reverse propulsion; due to the requirements of propellers for draft restrictions, the range of navigation is limited, or the propulsion direction of other bottom drive propellers is limited or other The azimuth bottom drive propeller has a large hydraulic direction change loss in the main propulsion direction due to the influence of the angle of the guide grid. [0003] CN201110054558 A kind of warping ship on water surface, including hull, buoy, swing steering mechanism and water propulsion mechanism, the hull is composed of front pipe, middle vertical pipe, rear pipe, horizontal pipe, bridge-shaped folded pipe, middle horizontal pipe, hoop and The panel is composed of buoys fixed on both s...
