Description

Technical Field

[0001] This invention relates to the field of electric motor technology, specifically to a novel protection device for gasoline engine generator sets. Background Technology

[0002] Gasoline engine sets, as power devices that use gasoline as fuel and convert the internal energy of the fuel into mechanical kinetic energy through internal combustion, are widely used in emergency power supply, outdoor operations, and mobile equipment. Their core component, the gasoline generator, typically consists of precision components such as a stator, rotor, end covers, and bearings, and achieves electrical energy conversion through the principle of electromagnetic induction. Currently, most gasoline engine sets are exposed during use or transportation, making them susceptible to damage; therefore, a protective casing needs to be installed on the outside of the generator.

[0003] For example, patent CN 212508544 U discloses a protective shell for a generator set, comprising a top cover, an outer shell, and a base connected sequentially from top to bottom. The outer shell and the base are detachably connected. The front side wall of the outer shell has an openable hatch, inside which is a control panel. A water tank is fixed to the upper part of the inner side wall of the outer shell, with the top of the water tank extending beyond the top cover. A support plate for housing an engine or motor is provided inside the outer shell, located above the base. Multiple shock absorbers are fixed to the front and rear outer walls of the support plate. The detachable connection between the outer shell and the base in the protective shell of this utility model makes the installation and disassembly of the protective shell very convenient and easy to operate.

[0004] However, existing protective shells have the following problems when in use: (1) The contradiction between the protective structure and transportation needs is prominent; most generator sets currently adopt open or semi-open designs, and key components are exposed to the external environment for a long time. During transportation, they are easily affected by collisions, rain and dust, which leads to a significant increase in equipment failure rate. Although some products improve their protective performance by adding metal shells, these rigid shells are prone to slippage due to their smooth surface during stacking and transportation, and the lack of positioning structure leads to misalignment between layers, which seriously restricts logistics efficiency; Vibration control and installation structure defects coexist; existing protective shells generally use bolted rigid connections to fix the generator set to the base, which, while ensuring structural strength, cannot effectively attenuate the vibration energy generated by engine operation. Experimental data shows that a 4-stroke gasoline engine at 3000 rpm can experience vibration acceleration of 5-8g. If this vibration is directly transmitted to the mounting base without isolation, it will not only accelerate fatigue damage to internal parts but also cause resonance interference to supporting equipment (such as medical equipment and precision instruments) through connecting pipelines, seriously affecting the stability of system operation.

[0005] Existing technical solutions either focus on enhancing protective strength or simply improving vibration damping materials, neither of which systematically solves the problem of synergistic optimization of protection, transportation, and vibration damping. Therefore, this invention proposes a novel integrated protective device. Summary of the Invention

[0006] The purpose of this invention is to provide a novel protection device for gasoline engine generator sets, in order to solve the problems mentioned in the background art, such as the installation of a protective casing affecting the heat dissipation of the gasoline engine, causing local overheating of the generator, accelerating the aging of parts, reducing the service life of the equipment, and the fact that in the design of the casing, the generator set is often directly fixed to the casing. The fixed connection method cannot reduce or offset the vibration force generated by the generator set during operation. Excessive vibration force will inevitably affect the generator set and the connected installation equipment.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a novel gasoline engine generator set protection device, comprising a base plate, a U-shaped plate installed on the outer side of the upper surface of the base plate, an mounting plate installed in the middle of the upper part of the base plate through a first buffer mechanism and a second buffer mechanism, a silicone pad fixedly connected to the upper surface of the mounting plate through a groove, slots provided at the four corners of the lower surface of the base plate, a housing provided above the base plate, inserts installed at the four corners of the upper surface of the housing, the inserts and the slots being movably connected by a pull-and-release mechanism, heat dissipation grooves provided on both sides of the outer surface of the housing, a dustproof net installed on the inner side of the heat dissipation grooves, multiple sound-absorbing plates evenly installed on both sides of the inner wall of the housing, multiple sound-absorbing holes evenly provided on the outer surface of the sound-absorbing plates, and sound-absorbing cotton provided on the inner side of the sound-absorbing holes.

[0008] The pull-and-disassemble mechanism includes a movable rod, which is installed at the front and rear of both sides of the outer surface of the housing through a round hole. A spring is sleeved on the outer surface of the movable rod, and a pull plate is fixedly connected to the opposite side of the outer surface of each pair of movable rods.

[0009] The other end of the movable rod is fixedly connected to a locking block. A first inclined surface is provided on one side of the lower end face of the locking block. A storage groove is provided on the inner side wall of the circular hole. The size of the locking block is smaller than the size of the storage groove.

[0010] A slot is provided on the opposite side of the outer surface of each pair of inserts, and the insert can be inserted into the inside of the slot. A second inclined surface is provided above the opposite side of the outer surface of each pair of inserts.

[0011] The first buffer mechanism includes a slider and a fixed seat. The slider is installed on the front and rear sides of the upper surface of the base plate through a transverse groove. The slider is connected to the inner wall of the transverse groove through a first damping rod. A first buffer spring is sleeved on the outer surface of the first damping rod.

[0012] The fixed base is fixedly installed on the front and rear sides of the lower end face of the mounting plate. A rotating rod is provided between the fixed base and the slider, and the rotating rod is hinged to the fixed base and the slider through a pin.

[0013] The second buffer mechanism is installed at the four corners of the lower end face of the mounting plate. The second buffer mechanism includes a second damping rod, and a second buffer spring is sleeved on the outer surface of the second damping rod.

[0014] The eccentric plate can be inserted into the inner side of the eccentric groove. The eccentric plate and the eccentric groove are fixedly connected by bolts. The four corners of the upper surface of the silicone pad are provided with first threaded holes, and the four corners of the upper surface of the groove are provided with second threaded holes.

[0015] The sound-absorbing plate is installed obliquely on both sides of the inner wall of the housing. The sound-absorbing plate is an aluminum plate. The diameter of the sound-absorbing hole is 8mm. The sound-absorbing cotton is centrifugal glass wool, and the sound-absorbing cotton is bonded to the inside of the sound-absorbing hole with acrylic resin.

[0016] The lower sides of both sides of the outer surface of the housing are provided with through holes, and the middle of the upper end face of the housing is provided with an oil inlet.

[0017] Compared with the prior art, the beneficial effects of the present invention are: 1. This invention, by providing a U-shaped groove and a U-shaped plate, facilitates the assembly and disassembly of the housing from above the base plate. The generator set is installed on top of the mounting plate through the first and second threaded holes. After installation, the housing is installed on top of the base plate. When the generator set needs to be transported, another base plate is installed on top of the housing. When the second inclined surface contacts the first inclined surface, the insert block compresses the locking block. Under the action of the spring, the locking block retracts into the inner side of the receiving groove. When the insert block is fully inserted into the inner side of the slot, the locking groove is flush with the receiving groove. At this time, the live... Under the action of the spring, the moving rod drives the locking block to push inward into the slot, and the locking block is locked into the inside of the slot, limiting the insertion block and completing the splicing of the two shells. When transported to the required location, the two pull plates are pulled in opposite directions, which drives the moving rod to move and move the locking block away from the inside of the slot, releasing the limitation on the insertion block and separating the shell from the bottom plate. This invention facilitates the stacking of generator sets, and the generator set at the top will not cause pressure or damage to the generator set at the bottom during transportation, while saving transportation space. 2. This invention incorporates a first buffer mechanism and a second buffer mechanism. When the generator set is operating, vibrations are generated. The first buffer spring deforms according to the force applied, absorbing some of the vibration energy. Simultaneously, the first damping rod converts the vibration energy into heat energy through its internal damping material, further reducing the vibration amplitude and providing lateral buffering for the vibrations generated by the gasoline engine generator. The second buffer spring deforms according to the force applied, absorbing some of the vibration energy. Simultaneously, the second damping rod converts the vibration energy into heat energy through its internal damping material, further reducing the vibration amplitude and providing vertical buffering for the vibrations generated by the gasoline engine generator. Furthermore, by incorporating sound-absorbing plates arranged at an angle and staggered on one side of the heat dissipation slot, sound waves entering the casing through the heat dissipation slot are forced to undergo multiple reflections and attenuation, improving the noise reduction effect. This invention offers excellent buffering and noise reduction performance. Attached Figure Description
