Description

Technical Field

In actual operation, it is very easy to encounter waterweeds or fishing lines, which may wind around the motor shaft or the propeller blades. It is relatively easy to clean on the propeller blades, but it is very difficult to clean when winding into the gap between the propeller and the motor. Slightly, it will affect the motor speed, and seriously, it will cause jamming, or damage the motor oil seal, resulting in motor failure. Summary of the Invention

[0020] The present utility model will be further described in detail below with reference to the drawings and embodiments. It can be understood that the specific embodiments described herein are only used to explain the present utility model, rather than limiting the present utility model. Additionally, it should be noted that for the sake of description, only parts related to the present utility model are shown in the drawings rather than all the structures.

[0021] Embodiment

[0022] Please refer to Figure 1 and 2, in the embodiment of the present utility model, a structure for preventing an underwater motor from being entangled with aquatic plants and fishing lines includes an underwater motor assembly, an oil seal 3, a propeller member 2, and a pressing block 4. The underwater motor assembly includes a motor shaft 5 and a motor housing 1. The oil seal 3 is fixed on the motor shaft 5. The propeller member 2 is connected to the motor shaft 5. The pressing block 4 is arranged between the oil seal 3 and the propeller member 2, nested on the motor shaft 5 and connected and fixed to the motor housing 1. An outer ring 6 is provided on the pressing block 4, and a first spike 8 and a second spike 9 are respectively designed on the outer ring 6 in the radial and axial directions.

[0023] Specifically, a first groove 12 is provided between the first spikes 8 on the outer ring 6 of the pressing block. The first groove 12 can preferably catch fishing lines and aquatic plants, facilitating cutting by the spikes.

[0024] Specifically, an inner ring 7 is further provided on the pressing block 4. The second spike 9 is designed on the inner ring 7 in the axial direction. During the rotation of the propeller, the spikes can well puncture and cut fishing lines or aquatic plants.

[0025] Specifically, on the surface of the propeller member 2 opposite to the pressing block 4, second grooves 13 are designed at positions corresponding to the outer ring 6 and the inner ring 7 on the pressing block 4. The pressing block 4 and the propeller member 2 are designed in an inserted shape, which can well prevent fishing lines and aquatic plants from penetrating deep into the motor shaft, and at the same time can catch fishing lines and aquatic plants, facilitating cutting by the spikes.

[0026] Specifically, a gasket 10 is provided between the motor shaft 5 and the propeller member 2. The gasket 10, the motor shaft 5, and the inner ring 7 of the pressing block form a third groove 14. Thinner fishing lines not cut by the outer ring will preferentially enter this third groove 14, without any impact on the oil seal. At the same time, the second spike 9 on the inner ring can cut fishing lines.

[0027] Specifically, the unilateral clearance between the pressing block 4 and the motor shaft 5 is 0.5 mm. Even if fishing lines enter, they will only accumulate on the inner wall of the force-bearing surface of the oil seal and cannot be pressed into the inner ring of the oil seal. This place is where the oil seal allows force to be applied and will not damage the oil seal.

[0028] Specifically, the pressing block 4 is in contact with the inner wall of the oil seal 3 to fix the oil seal 3 and prevent its axial displacement, thereby protecting the oil seal.

[0029] Specifically, the pressing block 4 is fixed on the motor housing 1 by screws 11, which is very easy to replace. After long-term use, if the spikes are worn, the user can replace them by himself. Moreover, both the first spike 8 and the second spike 9 are covered inside the motor housing 1 and not exposed to the outside, so there is no danger during the normal use of the user.

[0030] Based on the structure of the existing underwater motor, the utility model provides a structure for preventing water plants and fishing lines from being wound around an oil underwater motor, which well solves the problem that the fishing lines and water plants enter the inside of the motor shaft and cause the motor to jam, and effectively protects the oil seal, reducing the risk of oil seal displacement and damage.

[0031] Note that the above is only the preferred embodiment of the utility model and the technical principles applied. Those skilled in the art will understand that the utility model is not limited to the specific embodiments described herein. Various obvious changes, re-adjustments and substitutions can be made by those skilled in the art without departing from the protection scope of the utility model. Therefore, although the utility model has been described in more detail through the above embodiments, the utility model is not limited to the above embodiments only. Without departing from the concept of the utility model, more other equivalent embodiments can be included, and the scope of the utility model is determined by the scope of the appended claims.
