Abstract

A beam jet propellor is provided, especially a beam jet propellor which increases the friction force of the fluid by means of spiral or linear diversion protrusions or diversion grooves on the inner wall of a tube, such that original loose fluid can be twisted together into a beam shape under pressure/rotation/extrusion and form inter-tube pressure. The beam fluid may generate a strong propelling force. Meanwhile, because less air is included in this beam fluid, the bubble friction is smaller and acoustic noise is greatly decreased. The present invention does not adopt a traditional propellor as the propelling device, therefore, the cavitation due to ┌Bernoulli theorem┘ is not generated, and the problem of resistance force and drag force in the fluid is also eliminated. The propelling force is thus greatly increased.

Claims

1. A roller type beam jet propellor, comprising:

a beam diversion hollow tube having a diversion structure on the inner wall thereof, and said hollow tube has an inner diameter tapering from front to back or an equal inner diameter from front to back; and

a driving device for driving said beam diversion hollow tube to rotate so as to allow said diversion structure to twist the fluid in the tube together into a beam shape and form an inter-tube pressure to generate a propelling force.

2. The roller type beam jet propellor as claimed in claim 1, wherein said diversion structure is formed by protrusions or grooves.

3. The roller type beam jet propellor as claimed in claim 1, wherein said driving device further comprises a transmission device, and said transmission device is formed by at least one transmission axis.

4. The roller type beam jet propellor as claimed in claim 1, wherein said beam diversion hollow tube is provided with a water inlet mesh.

5. The roller type beam jet propellor as claimed in claim 1, wherein said beam diversion hollow tube further comprises a cleaning cover at the side wall for removing miscellaneous objects in the hollow tube.

6. The roller type beam jet propellor as claimed in claim 1, wherein said beam diversion hollow tube is formed by a plurality of modules.

7. The roller type beam jet propellor as claimed in claim 6, wherein washers and screws are provided for the assembly of said modules.

8. The roller type beam jet propellor as claimed in claim 1, utilized in a roller type quenching head device for fire tube as the propelling force.

9. The roller type beam jet propellor as claimed in claim 1, utilized in a pressure type quenching head device for fire tube as the propelling force.

10. A pressure type beam jet propellor, comprising:

a beam diversion hollow tube having a diversion structure on the inner wall thereof, and said hollow tube has an inner diameter tapering from front to back or an equal inner diameter from front to back; and

a fluid pressurizing device connected to said beam diversion hollow tube and providing a pressurized fluid into said beam diversion hollow tube so as to allow said diversion structure to twist the fluid in the tube together into a beam shape and form an inter-tube pressure to generate a propelling force.

11. The pressure type beam jet propellor as claimed in claim 10, wherein said fluid pressurizing device further comprises a pressurized fluid storage tank for storing the pressurized fluid.

12. The pressure type beam jet propellor as claimed in claim 10, wherein said fluid pressurizing device further comprises a delivery tank for stabilizing the connection between said beam diversion hollow tube and said pressurized fluid storage tank.

13. The pressure type beam jet propellor as claimed in claim 10, wherein said pressurized fluid storage tank further comprises at least one pressure safety valve.

14. The pressure type beam jet propellor as claimed in claim 10, wherein said delivery tank further comprises at least one counter reverse flow switch valve for avoiding a reverse flow when no pressure exists in said delivery tank.

15. The pressure type beam jet propellor as claimed in claim 10, wherein said diversion structure is formed by protrusions or grooves.

16. The pressure type beam jet propellor as claimed in claim 10, wherein said beam diversion hollow tube is provided with a water inlet mesh.

17. The pressure type beam jet propellor as claimed in claim 10, wherein said beam diversion hollow tube further comprises a cleaning cover at the side wall for removing miscellaneous objects in the hollow tube.
