[0002] A motor is an electromagnetic device that converts or transmits electrical energy according to the law of electromagnetic induction. Its main function is to generate driving torque as a power source for electrical appliances or various machines. The generator is represented by the letter G in the circuit. Its main function is to convert mechanical energy into electrical energy. At present, the most common method is to use heat energy, water energy, etc. to drive the rotor of the generator to generate electricity. With the rapid development of science and technology, the application scope of motors is becoming more and more extensive. In the following humid places or underwater, the application of motors is gradually needed. A sealing ring is usually provided between the shaft and the end cover of the waterproof motor to prevent water from entering the casing through the shaft.

[0003] After searching, it is found that a waterproof motor is disclosed in Chinese patent documents [Application number: 202122125342.4; Publication number: CN215990404U]. A waterproof motor includes a motor body, the end of the output shaft of the motor body is fixedly connected to a rotating shaft, a sealing mechanism for sealing is provided between the rotating shaft and the outer wall of the motor body, a protection mechanism for protecting the left side of the motor body is provided on the other side of the motor body, a fixing frame is fixedly connected to the lower end face of the motor body, a mounting plate is provided on the lower end face of the fixing frame, a fixing mechanism for fixing the fixing frame is provided between the mounting plate and the fixing frame, a power cord is provided on the upper end face of the motor body, and a waterproof joint is provided between the power cord and the motor body.

[0004] Although this patent ensures that the working environment of the motor is in a dry environment, thereby ensuring the working efficiency of the motor, the sealing ring is easily worn and needs to be replaced frequently. Since the sealing mechanism of this patent is a fixed structure, disassembly is cumbersome and it is not easy to replace the sealing ring. Utility Model Content

[0005] The purpose of the utility model is to address the above-mentioned problems in the existing technology and to propose a noise-reducing waterproof motor. The technical problem to be solved by the utility model is: how to achieve rapid disassembly and assembly of the motor and the sealing structure, so as to facilitate the replacement of its waterproof gasket and maintain the waterproof effect.

[0006] The purpose of the utility model can be achieved through the following technical solutions:

[0007] A noise-reducing waterproof motor comprises a motor body and a waterproof frame sleeved at the output shaft of the motor body, a noise-reducing tube sleeved at the output end of the motor body being fixed on the waterproof frame, a noise-reducing component being arranged in the noise-reducing tube, and the waterproof frame being threadedly connected to the motor body, waterproof gaskets being placed at the joints between the waterproof frame and the motor body, and a fixing component for quickly fixing to the motor body being arranged in the waterproof frame.

[0008] The working principle of the utility model is: the noise generated by the output end of the motor body when it is operating can be reduced by the noise reduction component arranged in the noise reduction tube, thereby realizing the noise reduction capability, and the waterproof frame and the motor body can be quickly disassembled and assembled by the fixing component, thereby facilitating the replacement of the waterproof gasket and maintaining the waterproof effect.

[0009] The noise reduction component comprises a plurality of noise reduction cavities which are arranged in an annular shape and penetrate the noise reduction tube, and a plurality of noise reduction spoilers which are fixed in each noise reduction cavity.

[0010] With the above structure, when the output end of the motor body is in operation, part of the sound energy generated by it is converted into heat energy and dissipated by friction in the gap of the noise reduction spoiler, thereby achieving noise reduction.

[0011] The fixing assembly includes a buckle rod slidably connected in the waterproof frame and a buckle slot provided on the motor body shell. A driving assembly for regulating the movement of the buckle rod is arranged in the waterproof frame, and one end of the buckle rod is buckled with the buckle slot.

[0012] With the above structure, the buckle rod can be controlled to move through the driving component, thereby realizing the buckle fit between the buckle rod and the buckle groove, and further realizing the rapid disassembly and assembly of the waterproof frame and the motor body, thereby facilitating the replacement of the waterproof gasket and maintaining the waterproof effect.

[0013] The driving assembly includes a bevel gear 1 rotatably connected to the waterproof frame, and a bevel gear 2 rotatably connected to the waterproof frame. The bevel gear 1 is meshed with the bevel gear 2, and a driving screw is coaxially fixed to the bevel gear 2. The driving screw is threadedly connected to the buckle rod.

[0014] By adopting the above structure, bevel gear one can rotate to drive bevel gear two to rotate. When bevel gear two rotates, it will drive the driving screw to rotate. When the driving screw rotates, it will push the snap rod to move through the threaded connection with the snap rod, thereby realizing the snap fit between the snap rod and the snap groove.

[0015] The waterproof frame is provided with a regulating wheel, which is coaxially fixedly connected with the bevel gear.

[0016] With the above structure, the bevel gear 1 can be driven to rotate by the regulating wheel, so that it is convenient for personnel to change the disassembly and assembly fixing state, thereby improving the convenience of operation.

[0017] Compared with the existing technology, this noise reduction waterproof motor has the following advantages:

[0018] 1. When the motor is running at the output end, part of the sound energy generated by it is converted into heat energy and dissipated by friction in the gap of the noise reduction spoiler, thereby achieving noise reduction.

[0019] 2. The driving assembly is used to control the movement of the buckle rod, thereby realizing the buckle fit between the buckle rod and the buckle groove, and further realizing the rapid disassembly and assembly of the waterproof frame and the motor body, so as to facilitate the replacement of the waterproof gasket and maintain the waterproof effect.

[0026] The noise reduction component provided in the noise reduction tube 3 can be used to reduce the noise generated at the output end of the motor body 1 when it is in operation, thereby achieving the noise reduction capability, and the waterproof frame 2 and the motor body 1 can be quickly disassembled and assembled through the fixing component, thereby facilitating the replacement of the waterproof gasket 4 and maintaining the waterproof effect.

[0027] The noise reduction component includes a plurality of noise reduction cavities 5 which are provided in an annular shape and penetrate the noise reduction tube 3 , and a plurality of noise reduction spoilers 6 which are fixed in each noise reduction cavity 5 .

[0028] With the above structure, when the output end of the motor body 1 operates, part of the sound energy generated by it is converted into heat energy and dissipated by friction in the gap of the noise reduction spoiler 6, thereby achieving noise reduction.

[0029] The fixing assembly includes a snap rod 7 slidably connected to the waterproof frame 2 and a snap groove 8 provided on the outer shell of the motor body 1. A driving assembly for regulating the movement of the snap rod 7 is provided in the waterproof frame 2, and one end of the snap rod 7 is snap-fitted with the snap groove 8.

[0030] With the above structure, the driving assembly can be used to control the movement of the snap rod 7, thereby achieving snap fit between the snap rod 7 and the snap groove 8, and further achieving rapid disassembly and assembly of the waterproof frame 2 and the motor body 1, thereby facilitating replacement of the waterproof gasket 4 and maintaining the waterproof effect.

[0031] The driving assembly includes a bevel gear 1 9 rotatably connected to the waterproof frame 2 and a bevel gear 2 10 rotatably connected to the waterproof frame 2. The bevel gear 1 9 is meshed with the bevel gear 2 10, and the bevel gear 2 10 is coaxially fixed with a driving screw 11, and the driving screw 11 is threadedly connected to the snap rod 7.
