The invention aims to provide a marine detachable guide pipe propeller which comprises a propeller, a telescopic rod, an adjusting mechanism and a detachable guide pipe, wherein the detachable guide pipe comprises a first guide pipe and a second guide pipe, the adjusting mechanism comprises a first gear, a second gear, a first bevel gear and a second bevel gear, the first gear is meshed with the second gear, the first bevel gear is meshed with the second bevel gear, the first gear and the second bevel gear are coaxial, the first gear is connected with the first guide pipe, the second gear is connected with the second guide pipe, a rotatable bevel gear transmission shaft is arranged in the telescopic rod, and the second bevel gear is fixed on the bevel gear transmission shaft. The invention can be folded or separated according to the working condition requirement, and when the propeller is heavier in load, the propeller efficiency can be improved by increasing the propeller thrust by folding the guide pipe. The guide pipe can be detached and taken back into the guide pipe cabin when the ship sails backwards and turns, and the maneuvering performance of the ship and the performance of the propeller during sailing backwards are improved.
Description
Technical Field
The invention relates to a ship propulsion device, in particular to a propeller.
Background
The ducted propeller is formed by adding an annular duct at the periphery of the propeller, and the section of the duct is in a wing shape or a broken-angle line shape. The guide pipe can improve the efficiency of the heavy-load propeller, so the guide pipe is widely applied to ships with heavier propeller loads. With the development of large-scale and high-power ships, the load of the propeller is larger and larger, and the ducted propeller not only can improve the propelling efficiency, but also is beneficial to reducing vibration. However, the ducted propeller has disadvantages such as an increase in the turning radius of the ship, deterioration in the handling performance, poor performance of the propeller when the ship sails backwards, and the like, and particularly, when waterweeds and impurities are drawn into the ducted propeller, the waterweeds and the impurities are easily stuck in the gap between the blade tip and the ducted propeller or wind the blades, which affects the operation, so that the ship sometimes has to be stopped for disposal.
Disclosure of Invention
The invention aims to provide a detachable ducted propeller for a ship, which can be folded or unfolded according to the requirements of working conditions.
The purpose of the invention is realized as follows:
the invention relates to a detachable ducted propeller for a ship, which is characterized in that: including screw, telescopic link, adjustment mechanism, removable branch pipe, but removable branch pipe includes first pipe and second pipe, adjustment mechanism includes first gear, second gear, first bevel gear, second bevel gear, and first gear meshes with the second gear mutually, and first bevel gear meshes with the second bevel gear mutually, and first gear is coaxial with the second bevel gear, and first pipe is connected to first gear, and the second pipe is connected to the second gear, sets up rotatable bevel gear transmission shaft in the telescopic link, and the second bevel gear is fixed on the bevel gear transmission shaft.
The present invention may further comprise:
1. when the first guide pipe and the second guide pipe are folded, an annular structure positioned on the periphery of the propeller is formed; after the first guide pipe and the second guide pipe are disassembled, the first guide pipe and the second guide pipe are driven by the first gear and the second gear to rotate upwards in opposite clockwise directions respectively.
2. The inside pipe cabin that sets up of hull above the screw, first pipe and second pipe upwards rotate the back, can retract into the pipe cabin under the drive of telescopic link.
3. The adjusting mechanism is arranged in the housing, and the housing is of a streamline structure.
The invention has the advantages that: the invention can be folded or separated according to the working condition requirement, and when the propeller is heavier in load, the propeller efficiency can be improved by increasing the propeller thrust by folding the guide pipe. The guide pipe can be detached and taken back into the guide pipe cabin when the ship sails backwards and turns, and the maneuvering performance of the ship and the performance of the propeller during sailing backwards are improved. When waterweeds, sundries and the like are drawn into the guide pipe and clamped between the blade tip of the propeller and the guide pipe or the propeller is wound by the blades to influence the normal work of the propeller, the guide pipe of the propeller can be opened to enable the sundries to automatically fall off or be convenient to clean. Not only can retain the advantages of the ducted propeller, but also can avoid the disadvantages of the ducted propeller.

Detailed Description
The invention will now be described in more detail by way of example with reference to the accompanying drawings in which:
with reference to fig. 1-4, the invention comprises a telescopic rod 1, an adjusting mechanism 2, a detachable conduit 3, a marine propeller 4 and the like, wherein the conduit 3 is detached and folded by the adjusting mechanism 2. The adjusting mechanism 2 for the disassembly and assembly of the propeller guide pipe adopts a gear transmission mechanism and comprises a gear 5, a gear 6, a bevel gear 7, a bevel gear 8, a bevel gear transmission shaft 9 and the like. The bevel gear transmission shaft 9 is driven by a motor or hydraulic pressure to drive the bevel gear 7, the gear 5 and the gear 6, so that the folding and the splitting of the guide pipe 3 are realized.
The gear 5 and the gear 6 are meshed with each other, the gear 5 and the gear 6 are fixed with two parts of the propeller guide pipe respectively, the gear 5 and the bevel gear 7 are fixed coaxially, and the bevel gear 7 and the bevel gear 8 are meshed with each other.
The bevel gear transmission shaft 9 can rotate in the telescopic rod 1 to drive the bevel gear 7 to drive the gear 5 and the gear 6, so that the catheter can be adjusted to be disassembled or assembled.
The housing of the duct-opening and closing adjusting mechanism 2 is streamlined to reduce drag and improve the flow field around the propeller.
The propeller guide pipe and the adjusting mechanism thereof can be retracted into a guide pipe cabin arranged in the ship body above the propeller through the telescopic rod 1.
The invention can be folded or separated according to the working condition requirement, and when the propeller 4 has heavier load, the guide pipe 3 is folded to increase the thrust of the propeller 4 and improve the efficiency of the propeller 4. The guide pipe 3 can be detached and retracted into the guide pipe cabin when the ship sails backwards and turns, and the maneuvering performance of the ship and the performance of the propeller 4 during sailing backwards are improved.
