Description

Technical Field

[0001] The utility model belongs to the technical field related to propellers, and particularly relates to a multifunctional propeller. Background Art

[0002] A propeller is a device that converts any form of energy into mechanical energy, generating thrust by rotating blades or jets (water). It can be used to drive vehicles forward. According to different principles, there are propeller propellers, jet propellers, water jet propellers, and special propellers. Most propeller propellers use gear meshing, so there will be noise and vibration. At the same time, the seal is prone to failure, resulting in oil leakage and water ingress, and there will be greater resistance and loss. Therefore, an annular propeller is used, and the annular propeller is composed of a rim-type motor, a propeller, a water-lubricated bearing, and an energy-saving fairing. The motor directly drives the propeller and transmits the force through the bearing. The energy-saving fairing further increases the thrust, eliminating all unnecessary parts that cause energy loss, failure, noise, and weight.

[0003] However, when using existing thrusters, most of them need to control the thrusters to rotate out of the equipment, which leads to an angular deviation between the thrusters and the mounting structure, which leads to leakage in the space between the thrusters and the mounting structure, resulting in reduced sealing, which makes the inside of the thrusters easy to leak. At the same time, the blades used by the existing thrusters cannot be easily disassembled, and the surface of the blades is easily damaged after long-term use of the thrusters, and they cannot be quickly replaced. To this end, we provide a multifunctional thruster to solve the above problems. Utility Model Content

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model. Specific embodiment 1

At the same time, the corrugated conduit 5 is installed between the U-shaped rotating seat 4 and the linkage pipe 101 to ensure the sealing.

[0030] Specifically, a rim motor 1 and an impeller 2 located at the inner side of the rim motor 1; a plurality of blades 3 are evenly distributed in an annular manner on the inner side of the impeller 2, an assembly rod 201 is fixed at the position of each blade 3 on the inner side wall of the impeller 2, and a sleeve 301 is fixed on the end surface of the blade 3 close to the impeller 2 and is sleeved on the circumferential side of the assembly rod 201; a linkage pipe 101 connected to the inner side of the rim motor 1 is fixed on the circumferential side of the outer side of the rim motor 1, and a linkage pipe 101 is arranged directly above the linkage pipe 101. A U-shaped swivel seat 4 is provided with a corrugated conduit 5 between the U-shaped swivel seat 4 and the linkage tube 101, a mounting hole 104 is provided on the upper end surface of the linkage tube 101, a mounting ring plate 404 is fixed on the upper end surface of the U-shaped swivel seat 4, a mounting hole 2 402 which is consistent with the upper and lower positions of the mounting hole 104 is provided inside the U-shaped swivel seat 4, and the upper and lower end surfaces of the corrugated conduit 5 are fixedly connected with mounting tubes 501 which are respectively fixed on the internal positions of the mounting hole 104 and the mounting hole 2 402.

[0031] The operation process of this embodiment is as follows: through the setting and use of the above-mentioned structure, when the rim motor 1 is controlled to work, it will drive the impeller 2 to rotate, and directly drive the blade 3 to rotate quickly, so as to perform propulsion work. At the same time, when the blade 3 needs to be disassembled, the blade 3 can be moved to the position of the axis of the impeller 2, so that the blade 3 will drive the sleeve 301 to be taken out at the peripheral position of the assembly rod 201, and then the blade 3 and the impeller 2 can be separated from the assembly connection, so that the damaged blade 3 can be replaced. In addition, due to the corrugated conduit 5 set between the U-shaped swivel seat 4 and the linkage pipe 101, when the rim motor 1 is used, the U-shaped swivel seat 4 can be installed and connected with the external equipment, and then the wires can be passed through the inside of the corrugated conduit 5, and then passed through the inside of the linkage pipe 101.

Specific embodiment 2

[0033] See also Figure 2 , 3 On the basis of the specific embodiment 1, the elastic pin rod 305 limits the insertion rod 303 to ensure the stability of the installation between the sleeve 301 and the assembly rod 201.

[0034] Specifically, a plurality of angle holes 202 are evenly distributed in a ring shape on the circumference of the assembly rod 201, and the angle holes 202 on the circumference of each assembly rod 201 are connected to each other, and two symmetrically arranged insertion holes 302 are penetrated on the circumference of the sleeve 301, and the insertion holes 302 and the adjacent angle holes 202 are in the same plane, and an insertion rod 303 is provided in front of the sleeve 301 to be inserted into the insertion holes 302 and the internal positions of the angle holes 202, and positioning holes 304 are penetrated on the front and rear end surfaces of the insertion rod 303 located at the front and rear of the sleeve 301, and elastic pin rods 305 are inserted into the interior of the positioning holes 304.

[0035] The operation process of this embodiment is as follows: when it is necessary to ensure the stable assembly between the sleeve 301 and the assembly rod 201, the sleeve 301 can be rotated to make the position of the insertion hole 302 on the side of the sleeve 301 consistent with the position of the angle hole 202, and then the insertion rod 303 is passed through the position of the insertion hole 302 and the angle hole 202, and the positioning holes 304 at the end of each insertion rod 303 are located at the front and rear parts of the sleeve 301, and then the elastic pin rod 305 is passed through the inside of the positioning hole 304. At this time, the elastic pin rod 305 limits the insertion rod 303 so that it cannot fall out from the inside of the insertion hole 302 and the angle hole 202, and then the sleeve 301 and the assembly rod 201 cannot fall off. At the same time, the angle of the blade 3 can be changed through the multiple angle holes 202 opened on the side of the assembly rod 201. Specific embodiment three

[0037] See also Figure 4 , 5 On the basis of the specific embodiment 1, the assembling work between the linkage tube 101 and the U-shaped rotating seat 4 is performed to ensure the stability of the adjustment of the rim motor 1.

[0038] Specifically, a rotating column 102 is fixed to the upper end surface of the linkage tube 101 located at the front and rear of the U-shaped rotating seat 4, and a circular plate 103 is fixed to the opposite end surfaces of the two rotating columns 102.
