Embodiment Construction

[0017] Referring to the accompanying drawings, the water jet propeller includes a main shaft 22, a helical impeller 29, a water suction pipe 31, a water spray pipe 33, a shell-shaped propeller main body 32, a bearing block 26, a shaft coupling 21, a front bearing gland 23, a front Support 25, rear bearing gland 27, rear support 28. The main body 32 of the propeller is a three-way pipe of equal diameter, that is, the diameters of the two water inlet pipes and one water outlet pipe are the same, and the two water inlet pipes are symmetrically distributed in an arc shape, and the diameter is the same as that of the water suction pipe 31. , the diameter of the outlet pipe is the same as that of the water spray pipe 33, and the two are also connected by flanges. The front end and the rear end in the main body of the propeller are respectively fixedly connected with a front bracket 25 and a rear bracket 28; the bearing seat is a straight pipe with a flange on the front end , the fro...

Abstract

The invention relates to a water spraying propeller. A main body of the propeller is a straight tee, two water inlet tubes are distributed symmetrically in the left-right direction in an arc-shaped manner and are connected with a water sucking tube by flanges; a water outlet tube is connected with a water spraying tube by a flange; the front end and the rear end of the inside of a shell of the propeller main body are fixedly connected with a front support and a rear support respectively; the flange of the front end of a bearing block is connected with the front support by a bolt; the rear end of the bearing block is connected with a rear bearing gland by a bolt; an embossment at the rear of the rear bearing bland is arranged in a blind hole of the rear support; the bearing block is positioned in the shell of the main body of the propeller; bearings at the front end and the rear end of a spindle are respectively arranged at the front end and the rear end of the bearing block; the spindle is positioned in the bearing block; the front end of the spindle is connected with a coupler; and the rear end of the spindle extends to the front of the water spraying tube and is provided with a spiral impeller. The water spraying propeller is simple in structure and low in cost, and is practical and reliable.

Description

technical field [0001] The present invention relates to a marine water jet propeller. Background technique [0002] Water jet propulsion has become a hot spot in the research of marine propulsion devices. For some small ships, compared with traditional propeller propulsion, water jet propulsion has the advantages of energy saving, efficiency increase and speed increase. But existing ship water jet propulsion also has defects such as sucking the bottom and sitting on the beach, troublesome manipulation. Contents of the invention [0003] The object of the present invention is to provide a water jet propeller in order to overcome the above disadvantages. It includes a main shaft, a helical impeller, a water suction pipe, a water spray pipe, a propeller main body, and a bearing seat. The invention is a practical and reliable water jet propulsor with simple structure, low cost. [0004] Technical scheme of the present invention is as follows: [0005] Water jet propeller...
