Description

Technical Field

[0001] This invention relates to the field of generator set technology, and in particular to a compact gasoline generator set. Background Technology

[0002] New energy internal combustion engines (hydrogen-ammonia) refer to engine technologies that use new low-carbon or zero-carbon fuels (such as hydrogen, methanol, natural gas, etc.) to drive the engine based on traditional internal combustion engines. This is an important direction for the transformation and upgrading of internal combustion engines under the current "dual carbon" goal. It usually includes a power component and a power generation component. The power component is the key component that converts chemical energy into mechanical energy. It generates kinetic energy by burning fuel in the cylinder, which drives the piston to reciprocate. This kinetic energy is then transmitted through the connecting rod to the crank to rotate and output power. The rotor then rotates and converts mechanical energy into electrical energy through the principle of electromagnetic induction. Compact diesel generators are widely used in various fields due to their portability and emergency response capabilities.

[0003] Existing gasoline generators mostly adopt an open frame structure, which lacks protection for core components. In particular, the fuel tank is located on the top, making it easy to be hit. Furthermore, when gasoline generators are working, they lack a noise reduction mechanism to prevent excessive noise pollution.

[0047] The technical solutions in the embodiments of the present invention will be clearly and completely described below. All other embodiments obtained by those skilled in the art without inventive effort are within the scope of protection of the present invention.

[0048] Example 1: Please refer to Figures 1-11 A compact gasoline generator set includes a generator set body 1 and a support frame 2 disposed on the outside of the generator set body 1.

[0049] The support frame 2 has symmetrically arranged positioning slots 21 at the top position; these positioning slots 21 are connected to the protective components.

[0050] The protective component includes a top cover plate 3 installed on the top of the generator set body 1 and auxiliary accessories installed on the side of the generator set body 1, and the auxiliary accessories are connected to the top cover plate 3; a handle 31 is fixedly installed on the top of the top cover plate 3 and a positioning strip 32 that is adapted to and engages with the positioning slot 21 is fixedly installed on the bottom side of the top cover plate 3.

[0051] According to the appendix Figure 1 - Appendix Figure 8 As shown, this solution provides a protective effect by setting a protective component on the outside of the generator set body 1, thus avoiding collision damage to the generator set body 1.

[0052] That is, the top cover plate 3 is set on the top of the support frame 2. The side of the top cover plate 3 is connected to the auxiliary accessories. In other words, the top cover plate 3 and the multiple load-bearing strips 501 form a protective side plate to achieve the anti-collision protection function.

[0053] Combined with the appendix Figure 9 - Appendix Figure 11 As shown, a first ventilation hole 402 is provided in the top cover plate 3 and a second ventilation hole 503 is provided in the bearing strip 501. The purpose is to ensure protection of the generator set body 1 while avoiding affecting the heat dissipation of the generator set body 1.

[0054] In addition, a first receiving slot 401 is provided on the inner side of the top cover plate 3 and a first sound-absorbing cotton plate 404 is provided in the first receiving slot 401. Similarly, a second receiving slot 502 is provided on the inner side of the bearing strip 501 and a second sound-absorbing cotton plate 506 is provided in the second receiving slot 502. That is, in addition to providing anti-collision protection for the generator set body 1, it can also reduce and absorb the noise generated by it, thereby reducing the pollution caused by its noise.

[0055] The protective components in this solution are easy to install and remove, and convenient to use.

[0056] Regarding the use of protective components, a first receiving slot 401 is located on the bottom side of the top cover plate 3, and first ventilation holes 402 are evenly arranged in the first receiving slot 401; a first sound-absorbing cotton plate 404 is also snapped into the first receiving slot 401; an installation groove 403 is provided on the side of the first sound-absorbing cotton plate 404, and a screw groove is provided in the installation groove 403; the installation groove 403 is connected to auxiliary accessories.

[0057] From the appendix Figure 1 and appendix Figure 4 - Appendix Figure 6As shown, the installation of the top cover plate 3 and the support frame 2 can be completed quickly and conveniently when installing the top cover plate 3. The positioning strip 32 set on the bottom side of the top cover plate 3 can be directly engaged with the positioning slot 21 on the top of the support frame 2.

[0058] In this way, the top cover plate 3 can be installed and used on site. After the work is completed, the top cover plate 3 can be lifted by holding the handle 31 until the positioning strip 32 on the bottom side of the top cover plate 3 is separated from the positioning slot 21 on the top of the support frame 2. The disassembly of the top cover plate 3 can be completed, which facilitates its handling and transportation.

[0059] Combined with appendix Figure 1 and appendix Figure 7 - Appendix Figure 10 As shown, the auxiliary accessories include a support strip 501; a second receiving slot 502 is provided on the back side of the support strip 501 and second ventilation holes 503 are evenly provided in the second receiving slot 502; a second sound-absorbing cotton board 506 is also snapped into the second receiving slot 502; multiple sets of support strips 501 form a protective side plate.

[0060] That is, the top cover plate 3 and its four protective side plates provide anti-collision protection for the generator set body 1. The protective side plates are spliced ​​together by multiple load-bearing strips 501, and adjacent load-bearing strips 501 are connected by connecting components.

[0061] While the top cover plate 3 and the protective side plate provide protection for the generator set body 1, in order to avoid affecting the heat dissipation of the generator set body 1, this solution provides a first ventilation hole 402 evenly in the top cover plate 3 and a second ventilation hole 503 in the bearing strip 501. This ensures protection for the generator set body 1 while also providing good heat dissipation, thereby preventing high temperature from affecting the operation of the generator set body 1.

[0062] To ensure heat dissipation, the first ventilation hole 402 and the second ventilation hole 503 solve the heat dissipation problem, but they also affect the noise reduction effect.

[0063] Therefore, from the appendix Figure 4 and appendix Figure 9 As shown, this solution also provides a first receiving slot 401 on the inner side of the top cover plate 3 and a first sound-absorbing cotton plate 404 in the first receiving slot 401, a second receiving slot 502 on the inner side of the bearing strip 501 and a second sound-absorbing cotton plate 506 in the second receiving slot 502.

[0064] In other words, the noise generated by the generator set body 1 is reduced by the combined use of the first sound-absorbing cotton plate 404 and the second sound-absorbing cotton plate 506.

[0065] To prevent the first sound-absorbing cotton plate 404 and the second sound-absorbing cotton plate 506 from blocking the first ventilation hole 402 and the second ventilation hole 503, thereby affecting the heat dissipation of the generator set body 1, this solution provides ventilation slots 601 evenly arranged in both the second sound-absorbing cotton plate 506 and the first sound-absorbing cotton plate 404. The ventilation slots 601 are truncated cone-shaped. The ventilation slots 601 in the first sound-absorbing cotton plate 404 are positioned corresponding to the first ventilation hole 402, and the number of sets is the same. The small end of the ventilation slot 601 is aligned with the first ventilation hole 402. Similarly, the ventilation slots 601 in the second sound-absorbing cotton plate 506 are positioned corresponding to the second ventilation hole 503, and the number of sets is the same. The small end of the ventilation slot 601 is aligned with the second ventilation hole 503.

[0066] In other words, ventilation slots 601 are provided on the first sound-absorbing cotton board 404 and the second sound-absorbing cotton board 506 to avoid affecting their heat dissipation while absorbing sound and reducing noise.

[0067] Then from the appendix Figure 11 As shown, this solution also includes a sound-absorbing buffer groove 602 in the ventilation cavity 601. That is, while heat is dissipated from the ventilation cavity 601, noise also flows out from the ventilation cavity 601. At this time, the sound-absorbing buffer groove 602 in the ventilation cavity 601 provides an auxiliary absorption effect for the passing noise, which has a positive impact on the overall sound absorption and noise reduction work.

[0068] Furthermore, the first sound-absorbing cotton board 404 is snapped into the first receiving slot 401 inside the top cover plate 3, and the second sound-absorbing cotton board 506 is snapped into the second receiving slot 502 inside the bearing strip 501. The first sound-absorbing cotton board 404 and the second sound-absorbing cotton board 506 are easy to assemble and disassemble, which facilitates later disassembly, cleaning, replacement and maintenance, and the operation is highly convenient.

[0069] Then from the appendix Figure 7 - Appendix Figure 8 As shown, for the use of the protective side plate, the back side of the bearing strip 501 at the top position of the protective side plate is fixedly provided with a mounting strip 504 that is adapted to and snaps into the mounting groove 403. The mounting strip 504 is fixed by mounting screws 505.

[0070] That is, when connecting the protective side plate to the top cover plate 3, the mounting clip 504 on the back side of the topmost load-bearing strip 501 is engaged with the mounting groove 403 on the side of the top cover plate 3, and then the mounting screws 505 are used to fix it.

[0071] For the connection between adjacent bearing strips 501, the connecting component includes placement grooves 701 on the left and right sides of the bearing strips 501, and screw grooves are provided in the placement grooves 701; the connecting component also includes a connecting rope 801 and mounting plates 802 at both ends of the connecting rope 801. The mounting plates 802 are installed in the placement grooves 701 and fixed by positioning screws 803. A knob body 804 is also fixedly provided at one end of the positioning screw 803.

[0072] That is, the adjacent bearing strips 501 are connected by a connecting rope 801. The connecting rope 801 is a soft rope. The two ends of the connecting rope 801 are placed in the placement grooves 701 on both sides of the adjacent bearing strips 501, and then fixed with positioning screws 803.

[0073] Here, a knob body 804 is fixed to one end of the positioning screw 803. When connecting and fixing the mounting plate 802, the operator can tighten the positioning screw 803 by pinching the knob body 804 with his hand, thus completing the installation of the mounting plate 802. No auxiliary tools are needed to complete the operation, which has good ease of operation.

[0074] Therefore, the use of load-bearing strips 501 can be increased or decreased according to actual needs, making it highly practical and flexible.

[0075] Combined with the appendix Figure 1 As shown, the adjacent load-bearing strips 501 have gaps, which play a positive role in the heat dissipation of the generator set body 1.

[0076] However, if high noise reduction is required, this solution also includes auxiliary magnetic sheets 901 embedded on the upper and lower sides of the bearing strip 501; the auxiliary magnetic sheets 901 between adjacent bearing strips 501 attract each other; that is, the upper and lower adjacent bearing strips 501 are brought into contact and positioned by attraction through the auxiliary magnetic sheets 901 to eliminate the gap between adjacent bearing strips 501. It can be adjusted according to the needs of on-site use, and has high work flexibility.

[0077] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
