[0001] This utility model relates to the field of vehicle-mounted generator set technology, and in particular to a protective box for a small generator set. Background Technology

[0002] Currently, when special vehicle manufacturers arrange and install vehicle-mounted generator sets, they often place the generator sets together with other equipment. This layout not only affects the normal operation of the generator sets, but the high temperature generated by the generator sets can also damage other equipment.

[0003] Chinese utility model patent CN111622837A discloses a diesel generator set and its protective box. The protective box, which covers the generator set, isolates other equipment and allows the exhaust pipe to be led downwards for discharge. A door is provided on the protective box for maintenance. However, this existing protective box has the following drawbacks: First, during vehicle operation, the exhaust gas from the generator set can easily flow back into the protective box, creating a safety hazard. Second, it does not have the function of shock absorption and noise reduction. Third, although it has a door, its function is limited and it is not convenient for ventilation and maintenance. Utility Model Content

[0004] In order to overcome the shortcomings in the background technology and solve the existing technical problems, this utility model discloses a small generator set protective box, which can not only isolate flue gas and prevent backflow, but also reduce vibration and noise, and facilitate protection and maintenance.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A protective box for a small generator set includes a base frame. A first shock absorber is installed on the lower surface of the base frame. A partition is erected and fixed at the rear end of the upper surface of the base frame, dividing the base frame into an installation area and an exhaust area for installing the generator set. The installation area is covered by a box cover. A rubber pad is provided between the edge of the box cover opening and the base frame. Both the front wall and the side wall of the box cover are provided with maintenance doors, and the maintenance doors on the side walls are equipped with louvers. Both sides of the exhaust area are provided with guide plates connected to the box cover.

[0007] Furthermore, the generator set includes a generator, a diesel engine, and a radiator arranged sequentially from the front end to the rear end of the installation area. An electrical box is mounted above the generator. A fuel heater and a controller are respectively provided on the sides of the generator and the electrical box. The exhaust pipe of the diesel engine is sealed through a partition and equipped with a muffler. A second shock absorber and a third shock absorber are respectively installed at the bottom of the generator and the diesel engine.

[0008] Furthermore, a rainproof eave is installed at the top of the maintenance door.

[0009] Furthermore, the side wall of the enclosure has two maintenance doors arranged side by side.

[0010] Furthermore, the guide plate and the housing, as well as the housing and the base frame, are detachably connected by bolts.

[0011] Furthermore, the base frame, partitions, and enclosure are all equipped with sound-absorbing layers.

[0012] Furthermore, a protective net is connected between the tops of the two deflectors.

[0013] Furthermore, the base frame is made of steel plate folded parts welded together, and the box cover and the guide plate are both made of aluminum plate folded parts welded together.

[0014] By adopting the technical solution described above, this utility model has the following beneficial effects:

[0015] This utility model discloses a small generator set protective box. By setting up partitions and guide plates, it can prevent the gas discharged into the exhaust area from flowing back into the installation area, thereby allowing the flue gas to be better discharged outside the box and avoiding damage to the generator set. By setting a first shock absorber on the base frame, the impact of the generator set's operating vibration on the outside world is reduced, as well as the impact of external vibration sources on the generator set's operation. The rubber pads can reduce the damage to the box cover caused by the generator set's operating vibration, increase the service life of the box cover, and avoid noise generated by metal collisions. In addition, by setting maintenance doors on multiple walls of the box cover, it is very convenient to directly inspect and maintain various components of the generator set at close range, and the added louvers can also facilitate ventilation and observation. In summary, this utility model is small and lightweight, easy to disassemble, and has a user-friendly structural layout, which facilitates the discharge of flue gas and the maintenance of the equipment inside the box cover, providing a good operating environment for the generator set.

[0019] The technical solution of this utility model will now be described with reference to the accompanying drawings of the embodiments of this utility model. In the description, it should be understood that the terms "upper," "lower," "front," "rear," "left," and "right," etc., indicating directions or positional relationships, are only used to correspond to the accompanying drawings of this utility model for ease of description, and do not indicate or imply that the device or element referred to must have a specific orientation.

[0020] Combined with appendix Figure 1-2 The small generator set protective box includes a base frame 1, which is welded from steel plates to ensure sufficient structural strength. A first shock absorber 2 is installed on the lower surface of the base frame 1. Generally, four first shock absorbers 2 are installed at the four corners of the base frame 1. A partition 10 is erected and fixed at the rear end of the upper surface of the base frame 1, dividing the base frame 1 into an installation area and an exhaust area for mounting the generator set. As needed, the generator set includes a generator 11, a diesel engine 14, and a radiator, arranged sequentially from the front to the rear of the installation area. An electrical box 15 is mounted above the generator 11. A fuel heater and a controller are respectively installed on the sides of the generator 11 and the electrical box 15. The exhaust pipe of the diesel engine 14 is sealed through the partition 10 and equipped with a muffler 16, ensuring quiet operation while venting gases to the exhaust area. A second shock absorber 12 and a third shock absorber 13 are respectively installed at the bottom of the generator 11 and the diesel engine 14. Through a series of vibration damping measures, the impact of generator set operation vibration on the external environment is reduced, as is the impact of external vibration sources on generator set operation.

[0021] The installation area is equipped with a housing cover 6. A rubber pad 3 is installed between the edge of the housing cover 6 and the base frame 1. The rubber pad 3 reduces damage to the housing cover 6 caused by unit operating vibration, increases the service life of the housing cover 6, and avoids noise generated by metal collisions. Maintenance doors 5 are provided on the front and side walls of the housing cover 6, corresponding to the generator 11, diesel engine 14, and electrical box 15 respectively, facilitating direct access for maintenance. If necessary, a rainproof eave 4 is installed at the top of the maintenance door 5 to prevent rainwater from entering the housing cover 6. In addition, two maintenance doors 5 are arranged side-by-side on the side walls of the housing cover 6. The maintenance door 5 of the wall is equipped with louvers 9, which facilitates ventilation and observation. Both sides of the exhaust area are equipped with guide plates 8 connected to the housing 6, which can block and guide the exhaust. The housing 6 and the guide plates 8 are both welded together from aluminum plate components, making the structure lighter. As needed, the guide plates 8 and the housing 6, as well as the housing 6 and the base frame 1, are detachably connected by bolts, which can facilitate individual or integrated disassembly and assembly. In addition, a protective net 7 is connected between the tops of the two guide plates 8, which can protect the external silencer and pipeline.

[0022] To further reduce noise, sound-absorbing layers can be provided on the base frame 1, partition 10, and enclosure 6 as needed.

[0023] By implementing the small generator set protective box described in this utility model, when the vehicle is moving, regardless of the direction of steering or speed change, the gas emitted by the diesel engine 14 in the exhaust area will be discharged outward due to the obstruction and guidance of the partition 10 and the guide plate 8, and will not flow back to the installation area; the installed shock absorbers and rubber pads 3 can also play a good role in shock absorption and noise reduction when the generator set is running. Moreover, the entire protective box is small and lightweight, easy to disassemble, and has a user-friendly structural layout, which facilitates the maintenance and repair of the equipment inside the box 6 and ensures the safe use of the generator set.
