Embodiment 1

[0033] Such as Figure 1 to Figure 6 As shown, this embodiment provides a shaftless pump propeller with a variable pitch angle, which includes an outer ring 1 and an inner ring 2 arranged coaxially. The inner ring 2 is provided with a number of blades 3 for rotation, and all the The paddles 3 are evenly distributed along the circumference of the inner ring 2 .

[0034] The inner diameter of the outer ring 1 is greater than the outer diameter of the inner ring 2, so that there is a gap between the outer ring 1 and the inner ring 2, and a useful An adjustment mechanism 4 for adjusting the angle of the paddle 3 .

[0035] Specifically, each of the paddles 3 corresponds to one of the adjustment mechanisms 4, and when the outer ring 1 moves along its axial direction, the adjustment mechanism 4 controls the paddles 3 to follow the movement of the outer ring 1. Move and rotate synchronously, so as to switch between the propulsion state, the braking state and the reverse state of th...

Embodiment 2

[0043] This embodiment is a further improvement on the basis of the above-mentioned embodiment 1. In order to better realize the present invention, the following structure is particularly adopted:

[0044]The shaftless pump thruster with variable pitch angle also includes a driving device for driving the outer ring 1 to move along its axial direction.

[0045] The driving device includes a first hydraulic cylinder 5 and a push ring 6, the push ring 6 is arranged coaxially with the outer ring 1, and the outer ring 1 is located in the push ring 6 and rotates with the push ring 6 In cooperation, the piston rod of the first hydraulic cylinder 5 is connected and fixed to the ring wall of the push ring 6 through the first push rod 7 .

[0046] In this embodiment, the outer ring 1 and the push ring 6 can adopt the matching method between the inner ring and the outer ring of the ball bearing in the prior art, specifically, as Figure 7 As shown, the outer wall of the outer ring 1 is ...

Abstract

The invention belongs to the technical field of shaftless pumping and particularly relates to a variable-helix-angle shaftless pumping propeller. The variable-helix-angle shaftless pumping propeller comprises an outer ring and an inner ring which are coaxially arranged, wherein a plurality of blades are rotatably arranged in the inner ring, all blades are uniformly distributed in the circumferential direction of the inner ring, the inner diameter of the outer ring is greater than the outer diameter of the inner ring, adjusting mechanisms for adjusting the angles of the blades are arranged between the outer ring and the inner ring, each blade corresponds to one adjusting mechanism, and when the outer ring moves in the axial direction, the adjusting mechanisms control the blades to synchronously rotate along with the movement of the outer ring, so that the blades are switched between a propelling state and a braking state. The variable-helix-angle shaftless pump propeller is simple and reasonable in structure, when the outer ring moves in the axial direction of the outer ring, the blade angles can be changed through the adjusting mechanisms, so that the blades are switched among a propelling state, a braking state and a backing state. The shaftless pump propeller can be widely applied to the technical field of shaftless pumping.

Description

technical field [0001] The invention belongs to the technical field of shaftless pump thrusters, and in particular relates to a shaftless pump thruster propeller with a variable helix angle. Background technique [0002] The existing shaftless pump propulsion technology is basically mature, but when a submarine using the shaftless pump propulsion technology is applied for emergency braking, it first needs to reduce the speed of the propeller and then reverse the rotation to achieve braking. The propeller is inertial due to its own volume and mass. Big, not easy to stall. Contents of the invention [0003] In order to solve the above-mentioned problems existing in the prior art, the present invention provides a shaftless pump propeller with a variable pitch angle, which is developed for the difficulty of propeller braking in the existing shaftless pump technology, and can be used without changing When the propeller turns, the propeller generates reverse thrust to perform d...
