Description

Technical Field

[0001] The invention relates to the technical field of jet nozzles, and in particular to a jet nozzle roll reduction and stabilization device. Background Art

[0002] A jet nozzle is a nozzle that accelerates a fluid and generates a high-speed jet. The fluid can be a water flow or an air flow. It can be used in a gas propulsion device or a water jet propulsion device to generate thrust by ejecting the fluid backward. For example, a water jet propulsion device equipped on a high-performance ship often has a steering demand in actual operation, and the nozzle needs to be rotated to adjust the propulsion direction. During the nozzle rotation and adjustment process, when the outlet end of the nozzle deviates from the center of the fluid, the pressure on the inner wall of the nozzle will be uneven. After long-term use, the nozzle will shake, aggravating the wear of the connection between the nozzle and the external device; and when the water flow pressure is unstable, the ejected jet will be uneven, and this unevenness will cause the nozzle to shake, which will also aggravate the wear of the connection between the nozzle and the external device. At the same time, the nozzle shaking phenomenon will cause the injection direction to deviate, which is easy to cause lateral interference to the forward direction.

[0003] For example, the technical solution with the announcement number: CN204554822U discloses a wave-type multi-curved surface diffusion jet nozzle. This technical solution adopts the key technology of "the nozzle is a wave-type multi-curved surface structure", which is composed of a cylinder A and a cylinder B. The cylinder B is a wave-type multi-curved conical cylindrical structure, and the cylinder A is fixedly connected to the cylinder B. The conical cross-section design adopted in the nozzle structure can alleviate the nozzle shaking phenomenon caused by the uneven jet. However, when the nozzle is adjusted in direction, the uneven jet phenomenon may be aggravated, thereby causing the nozzle shaking to intensify. The fixed structure of the conical cross-section cannot be adjusted accordingly, and the anti-roll effect will decrease accordingly. The wear of the nozzle and the external equipment will increase, and the stability is poor. Summary of the invention
