Driven by a turbine, steam turbine, diesel engine, or other power machinery, it converts energy generated by water flow, air flow, fuel combustion, or nuclear fission into mechanical energy, which is then transmitted to the generator, which then converts it into electrical energy. Generators are widely used in industrial and agricultural production, national defense, science and technology, and daily life. Generators come in many forms, but their operating principles are all based on the laws of electromagnetic induction and electromagnetic force.

[0027] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0028] Reference Figure 1-Figure 4 The utility model provides a technical solution: a noise reduction device for a generator, comprising a base 1 and a noise reduction mechanism 5. A mounting box 2 is installed on the top of the base 1, and a mounting groove 3 is opened on the surface of the mounting box 2. A guide plate 4 is installed on the left side of the base 1, which enables the base 1 to be installed on the mounting box 2 after installation, thereby facilitating the pulling or pushing of the generator into the mounting box 2 through the guide plate 4, and isolating the generator, so that the noise reduction mechanism 5 can block and absorb the noise generated by the operation of the generator, thereby reducing the noise impact generated when the generator is in use.

[0029] Reference Figure 1-Figure 3In a preferred embodiment, a noise reduction mechanism 5 is provided, which includes an inlay frame 51, a dustproof net 52 and a sound insulation board 53. The inlay frame 51 is installed in the inner cavity of the mounting groove 3, the dustproof net 52 is installed in the inner cavity of the inlay frame 51, and the sound insulation board 53 is installed on the inner wall of the mounting box 2. The sound insulation board 53 is located on the inner side of the inlay frame 51. The dustproof net 52 can be installed after the inlay frame 51 is installed. After the sound insulation board 53 is installed in the mounting box 2, the sound insulation board 53 can absorb the noise generated by the generator, thereby preventing floating dust in the external working environment from entering the mounting box 2, and preventing floating dust from entering the sound insulation board 53 and clogging the holes of the sound insulation board 53, thereby affecting the sound insulation and sound absorption effects of the sound insulation board 53.

[0030] Reference Figure 1-Figure 2 In a preferred embodiment, the top of the guide plate 4 is inlaid with balls 6, and several balls 6 are provided. A pad 7 is installed at the bottom of the guide plate 4, and the pad 7 is made of elastic material, so that after the pad 7 is inlaid, the pad 7 can contact the ground, support the guide plate 4, and prevent the protruding stones on the ground from affecting the guide plate 4 from being placed flat. In addition, a sliding groove 8 is opened on the left side of the installation box 2, and a blocking plate 9 is installed on the left side of the installation box 2. Sliding blocks 10 are installed on both sides of the right side of the blocking plate 9, and the sliding block 10 is slidably matched with the sliding groove 8. After the generator is placed in the installation box 2, the blocking plate 9 is moved downward, and the sliding block 10 is slidably matched with the sliding groove 8, which is convenient for placing the generator into the installation box 2, can reduce the spread of noise generated by the generator, and thus facilitate noise reduction.

[0031] Reference Figure 3 In a preferred embodiment, a mounting bracket 11 is installed on the inner wall of the mounting box 2, and a winding motor 12 is installed at the bottom of the mounting bracket 11, and the winding motor 12 is a dual-axis motor, and a winding drum 13 is installed at the output end of the winding motor 12, and support plates 14 are installed on both sides of the right side of the inner wall of the mounting box 2, and the winding drum 13 is rotatably connected to the support plate 14, and a pull rope 15 is installed on the surface of the winding drum 13, and a sleeve 16 is installed on the surface of the pull rope 15, and the sleeve 16 is made of elastic material, which can enable the winding motor 12 to be installed after the mounting bracket 11 is installed, so that the winding motor 12 drives the winding drum 13 to rotate after starting, so that the winding drum 13 can reel in the pull rope 15, and the pull rope 15 can pull the generator, and at the same time, the sleeve 16 on the surface of the pull rope 15 can fit with the surface of the generator to prevent the generator from directly contacting the pull rope 15 and causing the pull rope 15 to be worn.

[0032] Reference Figure 1-Figure 4In a preferred embodiment, a fixing frame 17 is installed on the right side of the installation box 2, and a fixing bracket 18 is installed in the inner cavity of the fixing frame 17, and a fan body 19 is installed on the left side of the fixing bracket 18, so that the fixing bracket 18 can be installed after the fixing frame 17 is installed, which facilitates the installation of the fan body 19 on the fixing bracket 18, and then facilitates the fan body 19 to blow air into the installation box 2 after starting, thereby cooling the winding motor 12 and the generator in the installation box 2, and a first filter 20 is installed in the inner cavity of the fixing frame 17, and a second filter 21 is inlaid on the right side of the inner cavity of the installation box 2, so that the first filter 20 can filter the incoming air, and the installed second filter 21 can filter the dust in the air again, which can provide a better working environment for the generator.

[0033] Specifically, the working process or working principle of the noise reduction device for the generator is as follows: when in use, the generator is moved to the guide plate 4, and the pull rope 15 is pulled so that the pull rope 15 passes around the generator and the sleeve 16 fits with the surface of the generator, and then the winding motor 12 is started, so that the winding motor 12 drives the winding drum 13 to rotate, and the pull rope 15 can be wound, so that the pull rope 15 pulls the generator to move to the guide plate 4, thereby pulling the generator into the installation box 2, and then the blocking plate 9 is moved downward to isolate the generator into the installation box 2, and then the fan body 19 is started so that the fan body 19 blows air into the installation box 2, thereby allowing the air in the installation box 2 to circulate and the generator to cool down, avoiding overheating and overload caused by long-term use of the generator. When the generator is running, the sound insulation board 53 can block and absorb the noise generated by the generator, avoiding the noise generated by the generator during operation from spreading and affecting the surrounding working environment.

[0034] It should be noted that the winding motor 12 is a device or equipment existing in the prior art, or a device or equipment that can be realized in the prior art. Its power supply, specific composition and principle are clear to those skilled in the art, so they are not described in detail.
