[0002] Noise pollution has become one of the important environmental problems facing modern society. It not only affects people's daily quality of life, but may also have long-term impacts on people's health. Therefore, strengthening noise control is of great significance to protecting the ecological environment and improving people's quality of life.

[0003] In actual applications, medium and large generators are usually installed with fixed sound insulation enclosures. This design is particularly common in emergency power generation scenarios in municipal construction, building construction, and corporate operations. However, for small generators, since their usage scenarios usually involve mobility, this fixed sound insulation enclosure design cannot be adopted. Small generators need to temporarily generate electricity in different locations, which requires their sound insulation measures to be flexible and portable so that they can be quickly installed and disassembled in different environments. Utility Model Content

[0004] The technical problem to be solved by the present invention is that in the prior art, existing generator sound insulation covers mainly use a main body material with a certain sound insulation capacity and a fully enclosed installation method to achieve noise reduction effects. In actual use, fixed sound insulation covers are mainly installed on medium and large generators, which are commonly used in emergency power generation scenarios such as municipal construction, building construction, and corporate operations. However, small generators cannot adopt fixed sound insulation covers due to their mobile usage scenarios. For this reason, we propose a portable generator sound insulation cover.

[0006] Preferably, a notch is provided at the bottom of the fixed block, two toggle blocks are installed inside the notch, limiting holes are provided at both ends of the toggle block, a limiting rod is fixedly connected to the inside of the notch, the surface of the limiting rod is slidably connected to the inside of the limiting hole, a clamping block is fixedly connected to one end of the toggle block, through slots are provided at both ends of the inner cavity of the notch, and clamping slots are provided at both ends of the hollow block.

[0007] Preferably, the inner shape of the card slot matches the outer shape of the card block.

[0008] Preferably, one end of the toggle block is fixedly connected to a return spring, and one end of the return spring is fixedly connected to the inside of the notch.

[0020] The present invention will now be described in further detail with reference to the accompanying drawings and preferred embodiments. These drawings are simplified schematic diagrams that only illustrate the basic structure of the present invention in a schematic manner, and therefore only show components related to the present invention.

[0021] Reference Figure 1 - Figure 4 As shown, the utility model provides a technical solution: a portable generator sound insulation cover, comprising a left side panel 1 and a right side panel 2, the top hinge of the left side panel 1 is connected to the top panel 3, one end of the right side panel 2 is hingedly connected to the back panel 4, an adjustable panel 5 is installed on one side of the right side panel 2, a support rod 6 is installed on the bottom of the top panel 3, the bottoms of the top panel 3 and the adjustable panel 5 are fixedly connected to a fixed block 7, one end of the fixed block 7 is provided with an elliptical groove 8, the inside of the elliptical groove 8 is slidably connected to a first round rod 9, both ends of the first round rod 9 are rotatably connected to a connecting rod 10, one side of the right side panel 2 is fixedly connected to two hollow blocks 11, one end of the support rod 6 is fixedly connected to the hollow block 11, A second round rod 12 is installed inside the hollow block 11, and both ends of the second round rod 12 are rotatably connected to the two ends of the connecting rod 10. A plurality of threaded holes 13 are opened on the top of the left side panel 1, the back panel 4 and the top panel 3. The internal threads of the threaded holes 13 are connected to threaded rods 14. The staff twists the plurality of threaded rods 14 upwards to release the fixed relationship between the left side panel 1 and the top panel 3 and the back panel 4. Then, by folding the left side panel 1, the top panel 3 and the support rod 6, and folding the adjustable panel 5 in half, and folding the back panel 4 and the right side panel 2 in half, the sound insulation enclosure can be quickly installed and dismantled on site. At the same time, the sound insulation enclosure can be folded into two main structures, which occupies a small area and is convenient for transportation.

[0022] Reference Figure 3 and Figure 5As shown, in this embodiment: a notch 15 is provided at the bottom of the fixed block 7, and two toggle blocks 16 are installed inside the notch 15, and both ends of the toggle block 16 are provided with a limit hole 17, the interior of the notch 15 is fixedly connected to a limit rod 18, and the surface of the limit rod 18 is slidably connected to the interior of the limit hole 17, and one end of the toggle block 16 is fixedly connected to a clamping block 19, and both ends of the inner cavity of the notch 15 are provided with a through slot 20, and both ends of the hollow block 11 are provided with a clamping slot 21. When the angle between the fixed block 7 and the hollow block 11 is in the ninety-degree open state, the toggle block 16 is moved, so that the toggle block 16 drives the clamping block 19 to be inserted into the interior of the clamping slot 21, so that the angle between the fixed block 7 and the hollow block 11 remains fixed, thereby maintaining the stability of the support rod 6 and the adjustable plate 5 structure, and thus allowing the staff to freely adjust the opening angle of the right side plate 2 and the adjustable plate 5, and adjust the ventilation and heat dissipation angle and the noise prevention angle according to the working conditions of the generator.

[0023] Reference Figure 5 As shown, in this embodiment: the internal shape of the card slot 21 is consistent with the external shape of the card block 19. The shape matching of the card slot 21 and the card block 19 ensures that the card block 19 can be tightly locked in the card slot 21, thereby enhancing the stability of the connection.

[0024] Reference Figure 5 As shown, in this embodiment: one end of the toggle block 16 is fixedly connected to a return spring 22, and one end of the return spring 22 is fixedly connected to the inside of the slot 15. The setting of the return spring 22 enables the toggle block 16 to start accumulating force when it is pressed inward. When the toggle block 16 is released, the return spring 22 can quickly restore the toggle block 16 to its initial position, making it faster for staff to use.

[0025] Reference Figure 6 As shown, in this embodiment: the left side panel 1, the right side panel 2, the top panel 3, the back panel 4 and the adjustable panel 5 are all installed with sound insulation cotton 23 and a perforated panel 24. The perforated panel 24 and the sound insulation cotton 23 can achieve good sound insulation and noise reduction effects by adjusting parameters such as density and aperture, thereby reducing noise and improving the quality of the acoustic environment.

[0026] Reference Figure 2 As shown, in this embodiment: the adjustable plate 5 is a fan-shaped structure with a central angle of about sixty-five degrees. The fan-shaped structure can more effectively control the propagation path and reflection of sound. By adjusting the angle of the adjustable plate 5, the reflection and refraction of sound inside the soundproof enclosure can be changed, thereby reducing sound leakage and enhancing the sound insulation effect, which helps to reduce the noise level when the generator is running and provide a quieter atmosphere for the surrounding environment.

[0027] Working principle: The staff twists the multiple threaded rods 14 upwards to release the fixed relationship between the left side panel 1 and the top panel 3 and the back panel 4, and then folds the left side panel 1, the top panel 3 and the support rod 6, and folds the adjustable panel 5 in half, and folds the back panel 4 and the right side panel 2 in half, so that the sound insulation cover can be quickly installed and removed on site. At the same time, the sound insulation cover can be folded into two main structures, which occupies a small area and is convenient for transportation. When the angle between the fixed block 7 and the hollow block 11 is in the ninety-degree open state, the toggle block 16 is moved so that the toggle block 16 drives the card block 19 to be inserted into the inside of the card slot 21, so that the angle between the fixed block 7 and the hollow block 11 remains fixed, so that the support rod 6 and the adjustable panel 5 maintain the stability of the structure, and then the staff can freely adjust the opening angle of the right side panel 2 and the adjustable panel 5, and can adjust the ventilation and heat dissipation angle and the noise prevention angle according to the working conditions of the generator. The shape matching of the slot 21 and the block 19 ensures that the block 19 can be tightly locked in the slot 21, thereby enhancing the stability of the connection. The setting of the return spring 22 enables the toggle block 16 to start accumulating force when pressed inward. When the toggle block 16 is released, the return spring 22 can quickly restore the toggle block 16 to its initial position, making it faster for staff to use. The perforated panel 24 and the sound insulation cotton 23 can achieve good sound insulation and noise reduction effects by adjusting parameters such as density and aperture, reduce noise, and improve the quality of the acoustic environment. The fan-shaped structure can more effectively control the propagation path and reflection of sound. By adjusting the angle of the adjustable plate 5, the reflection and refraction of sound inside the soundproof enclosure can be changed, thereby reducing sound leakage and enhancing the sound insulation effect, which helps to reduce the noise level during generator operation and provide a quieter atmosphere for the surrounding environment.

[0028] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention.
