DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in 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.

[0024] like Figure 1 , Figure 2 As shown, this embodiment provides a technical solution: a balancing device for a submersible flow propeller, comprising a shaft housing 1, a shaft body 7 is arranged on the inner side of the shaft housing 1, and a shaft damping assembly 9 is arranged on the outer side of the shaft body 7;

[0025] The rotating shaft shock absorbing assembly 9 includes a fixing plate 93, on which a shock absorbing damper 94 is arranged, on which a screw rod 95 is arranged, and a rotating shaft fixing ring 91 is arranged on the top of the shock absorbing damper 94, and the screw rod 95 passes through the rotating shaft fixing ring 91. The shock absorbing damper 94 can effectively reduce the vibration generated by the rotating shaft body 7 during the rotation process, thereby reducing noise. The fixing plate 93 and the rotating shaft fixing ring 91 work together to firmly fix the shock absorbing damper 94 on the fixing plate 93 to ensure its stability and vibration reduction effect.

[0026] Further, such as Figure 1 , Figure 3 As shown in the figure: the rotating shaft body 7 is provided with a rotating shaft slot 92, the fixing plate 93 clamps the rotating shaft damping assembly 9 on the outer side of the rotating shaft body 7 through the rotating shaft slot 92, the end of the screw rod 95 away from the damping damper 94 penetrates the rotating shaft housing 1, and the other end of the screw rod 95 is provided with a nut 4, and the outer side of the rotating shaft body 7 is designed with rotating shaft slots 92 distributed at equal distances, which provide accurate positioning points for the fixing plate 93. The fixing plate 93 is combined with the rotating shaft slot 92, so that the rotating shaft damping assembly 9 can be firmly installed on the periphery of the rotating shaft body 7. This installation method not only ensures the stability of the damping damper 94, but also allows it to play the maximum efficiency in absorbing and alleviating the vibration in the rotating shaft movement. The damping damper 94 is provided with a screw rod 95, which is used to penetrate the rotating shaft housing 1 and closely connect the interior of the rotating shaft body 7 with the rotating shaft housing 1. The other end of the screw rod 95 is provided with a nut 4, and the screw rod 95 can be locked by rotating the nut 4, so that a solid connection whole can be formed from the inside to the outside.

[0027] In the above scheme, there is still vibration generated when the motor body 6 rotates the shaft body 7, such as Figure 2 , Figure 4As shown: a motor body 6 is arranged on the side of the rotating shaft body 7 away from the propeller rotating shaft 3, a motor damping assembly 8 is arranged on the motor body 6, and the motor damping assembly 8 comprises a fixing ring 1 81, a connecting rod 82 is arranged on the fixing ring 1 81, a fixing ring 2 85 is arranged on the other end of the connecting rod 82, a damping spring 83 is arranged inside the connecting rod 82 and the fixing ring 2 85, and a nut 2 84 is arranged on both sides of the connecting rod 82. Through the connecting rod 82, the fixing ring 1 81 and the fixing ring 2 85 are firmly connected to form a solid frame that can withstand the vibration force generated when the motor is running. Inside this frame, the damping spring 83 is cleverly arranged. It is placed between the fixing ring 1 81 and the fixing ring 2 85, and uses its elastic characteristics to absorb and alleviate the vibration generated during the operation of the motor, effectively reducing the noise and improving the stability of the motor. In order to ensure the stability of this shock-absorbing structure during use, nuts 2 84 are installed on both sides of the connecting rod 82. These nuts can adjust the tightness of the connecting rod 82, thereby further strengthening the connection between the fixing ring 1 81 and the fixing ring 2 85. The motor housing 2 provides a protective barrier for the entire motor shock-absorbing assembly 8, which not only protects the internal shock-absorbing mechanism from external influences, but also plays an additional safety role, preventing any possible injury or damage caused by vibration during the operation of the motor.

[0028] Working principle:

[0029] like Figure 1-4As shown in the figure, the shaft slots 92 uniformly opened on the outer side of the shaft body 7 provide an anchoring position for the fixing plate 93, so that the shaft shock-absorbing assembly 9 can be firmly fixed to the periphery of the shaft body 7. This structure facilitates the vibration reduction effect of the shock-absorbing damper 94 to be directly applied to the shaft body 7, effectively reducing the vibration and noise generated during rotation. The fixing plate 93 cooperates with the shaft fixing ring 91 to ensure the stability and reliability of the shock-absorbing damper 94. The shock-absorbing damper 94 is equipped with a screw 95, which passes through the shaft housing 1 and is fixed by means of a nut 4 at the other end, thereby tightly connecting the internal components of the shaft with the housing. This design improves the stability of the overall structure and prevents loosening or relative displacement between components. The connecting rod 82 connects the fixing ring 81 with the fixing ring The two 85 are tightly connected, and the inner shock-absorbing spring 83 is responsible for absorbing the vibration generated when the motor is running. By adjusting the nuts 84 on both sides of the connecting rod 82, the tightness between the fixing rings can be accurately controlled, thereby achieving fine-tuning of the entire shock-absorbing system. The motor housing 2 not only protects the internal motor and shock-absorbing components, but also isolates the external environment and prevents the entry of debris. The cover plate 10 is used to close the shaft housing 1, further protecting the shaft body 7 and the shaft shock-absorbing component 9 from external influences. Through the combination of the motor shock-absorbing component 8 and the shaft shock-absorbing component 9, the submersible thruster is given better stability and balance during operation. These carefully designed structures ensure that the equipment can operate smoothly even in harsh underwater environments.

[0030] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
