Description

Technical Field

[0001] The present invention relates to the field of propellers, and particularly to an anti-entanglement propeller mechanism. Background Art

[0002] Existing anti-entanglement technologies mostly use mesh covers or cutting. Using a mesh cover affects the propulsion efficiency and cannot prevent fine ropes or garbage. Cutting for anti-water entanglement can only be used in high-power places and is not very suitable for small propellers such as ROVs in complex environments such as sewer pipes and ponds where there is a lot of garbage like fishing lines and waterweeds. Summary of the Invention

[0003] The main object of the present invention is to provide an anti-entanglement propeller mechanism, aiming to solve the above technical problems.

[0004] To achieve the above object, an anti-entanglement propeller mechanism proposed by the present invention includes a motor component, a sealing component disposed on the end face of the motor component, and a blade component connected to the output shaft of the motor component. The sealing component includes a first wear-resistant ring and a second wear-resistant ring. The first wear-resistant ring is fixedly installed on the motor component, and the second wear-resistant ring follows the blade component so that the first wear-resistant ring and the second wear-resistant ring are in contact with each other and have relative rotation.

[0005] In one embodiment, the motor component includes a motor bracket and a motor body installed on the motor bracket. The motor bracket has a through hole for exposing the output shaft of the motor body, and the first wear-resistant ring is connected to the fixed bracket and disposed at the end face of the through hole.

[0006] In one embodiment, the fixed bracket is provided with a positioning protrusion, and the first wear-resistant ring is provided with a positioning groove cooperating with the positioning protrusion.

[0007] In one embodiment, the blade component includes a mounting shaft and a propeller blade disposed outside the mounting shaft. The output shaft is connected to the mounting shaft, and the end face of the mounting shaft is in contact connection with the first wear-resistant ring through the second wear-resistant ring.

[0008] In one embodiment, the sealing component further includes a silica gel pad disposed between the end face of the mounting shaft and the second wear-resistant ring.

[0009] In one embodiment, the first wear-resistant ring, the second wear-resistant ring, the fixed bracket, and the outer diameter of the mounting shaft are the same.

[0010] In one embodiment, the propeller blade is an integral continuous propeller blade disposed outside the mounting shaft.

[0011] In one embodiment, the blade component further includes a fixing base. An installation cavity is recessed inward from the axis of the installation shaft, and the fixing base is arranged in the installation cavity and butted against the fixing bracket.

[0012] In the technical solution of the present invention, the anti-winding propeller mechanism includes a motor component, a sealing component disposed on the end face of the motor component, and a blade component connected to the output shaft of the motor component. The sealing component includes a first wear-resistant ring and a second wear-resistant ring. The first wear-resistant ring is fixedly installed on the motor component, and the second wear-resistant ring follows the blade component so that the first wear-resistant ring and the second wear-resistant ring are in contact with each other and have relative rotation. Therefore, in this technical solution, through the contact between the first wear-resistant ring and the second wear-resistant ring, the motor component and the blade component are closely attached without gaps. During the relative rotation of the first wear-resistant ring and the second wear-resistant ring, impurities are difficult to enter the motor component, thereby improving the sealing performance.

[0024] The present invention provides an anti-winding propeller mechanism.

[0025] As Figure 1-2 shown, the anti-winding propeller mechanism provided by the embodiment of the present invention includes a motor component 10, a sealing component 20 disposed on the end face of the motor component 10, and a blade component 30 connected to the output shaft 15 of the motor component 10. The sealing component 20 includes a first wear-resistant ring 21 and a second wear-resistant ring 22. The first wear-resistant ring 21 is fixedly installed on the motor component 10, and the second wear-resistant ring 22 follows the blade component 30 so that the first wear-resistant ring 21 and the second wear-resistant ring 22 are in contact with each other and have relative rotation.

[0026] In this embodiment, the anti-twist propeller mechanism includes a motor component 10, a sealing component 20 disposed on the end face of the motor component 10, and a blade component 30 connected to the output shaft 15 of the motor component 10. The sealing component 20 includes a first wear-resistant ring 21 and a second wear-resistant ring 22. The first wear-resistant ring 21 is fixedly installed on the motor component 10, and the second wear-resistant ring 22 follows the blade component 30 so that the first wear-resistant ring 21 and the second wear-resistant ring 22 are in abutting contact with each other and have relative rotation. Therefore, in this technical solution, through the abutting contact between the first wear-resistant ring 21 and the second wear-resistant ring 22, the motor component 10 and the blade component 30 are closely attached without gaps. During the relative rotation of the first wear-resistant ring 21 and the second wear-resistant ring 22, impurities are difficult to enter the motor component 10, thereby improving the sealing performance.

[0027] Among them, the motor component 10 includes a motor bracket 12 and a motor body 11 installed on the motor bracket 12. The motor bracket 12 has a through hole 13 for exposing the output shaft 15 of the motor body 11. The first wear-resistant ring 21 is connected to the fixed bracket and disposed at the end face of the through hole 13 to facilitate the docking of the output shaft 15 and the blade component 30.

[0028] The fixed bracket is provided with a positioning protrusion 14, and the first wear-resistant ring 21 is provided with a positioning groove 24 that cooperates with the positioning protrusion 14. Therefore, the first wear-resistant ring 21 can be prevented from following the first wear-resistant ring 21 through the cooperation of the positioning protrusion 14 and the positioning groove 24. When the first wear-resistant ring 21 follows the blade component 30, there is no gap (i.e., abutting) between the two end faces of the first wear-resistant ring 21 and the second wear-resistant ring 22, and the friction coefficient is low, which can resist wear for a long time.

[0029] Please refer to Figure 3-4 , the blade component 30 includes a mounting shaft 31 and a propeller blade 32 disposed outside the mounting shaft 31. The output shaft 15 is connected to the mounting shaft 31, and the end face of the mounting shaft 31 is in abutting connection with the first wear-resistant ring 21 through the second wear-resistant ring 22. In this embodiment, a silica gel pad 23 is further provided between the mounting shaft 31 and the first wear-resistant ring 21. The silica gel pad 23 has high elasticity. Therefore, through the silica gel pad 23, not only can the gap between the first wear-resistant ring 21 and the second wear-resistant ring 22 be reduced by means of pressing, but also a buffering effect can be achieved.

[0030] The blade component 30 further includes a fixing seat 33. An installation cavity is recessed inward from the axis of the installation shaft 31, and the fixing seat 33 is disposed in the installation cavity and docked with the fixed bracket. In this embodiment, a set screw is provided on the outer surface of the fixing seat 33 and fixed to the output shaft 15 through the set screw.

[0031] Optionally, the outer diameters of the first wear-resistant ring 21, the second wear-resistant ring 22, the fixing bracket, and the mounting shaft 31 are the same. Please refer to Figure 3 , in this embodiment, the same outer diameter only refers to the same outer diameter at the connecting part, forming an integral body in appearance.

[0032] In the above embodiment, the propeller blade 32 is an integral continuous propeller blade 32 arranged outside the mounting shaft 31. The diameter of the propeller blade 32 gradually changes from small to large and then to small. When impurities are outside the sealing member 20, they will be sent to the rear end through the spiral mechanism of the continuous blade, thus preventing entanglement.

[0033] The above are only the preferred embodiments of the present invention, and do not limit the patent scope of the present invention accordingly. Any equivalent structural transformation made under the concept of the present invention by using the content of the specification and drawings of the present invention, or directly / indirectly applied in other related technical fields, is included in the patent protection scope of the present invention.
