Description

Technical Field

[0001] The utility model relates to a small-sized power generation equipment, in particular to a generator. Background Art

[0002] A generator is a mechanical device that converts mechanical energy into electrical energy. It is driven by a turbine, steam turbine, diesel engine or other power machinery, and converts the energy generated by water flow, air flow, fuel combustion or nuclear fission into mechanical energy and transmits it to the generator, which then converts it into electrical energy.

The cooling air entering the cylinder head air duct is discharged from the first air outlet, and the cooling air entering the box bottom air duct is discharged from the second air outlet, thereby improving the cooling effect of the engine. In the prior art, the control panel is installed on the shell, so when assembling the shell, it is necessary to match the control panel on the shell with the corresponding control device in the shell before assembling the shell, which reduces the assembly efficiency on the one hand and increases the processing cost of the shell on the other hand. Utility Model Content

[0004] In order to solve the technical problems of low generator housing assembly efficiency and high cost in the prior art, the utility model provides a generator, including a housing, an engine and matching functional components, the housing including a base plate and an upper cover; wherein: the upper cover is mounted on the base plate, the base plate and the upper cover are connected to form a chamber for mounting the engine and the functional components, the engine and the functional components are mounted on the base plate and supported by the base plate.

[0005] Compared with the prior art, in this solution, after all the functional components of the generator are set on the bottom plate, the upper cover only serves to cover all the functional components. There is no need for corresponding settings between the functional components or the problem that some parts of the upper cover can only be installed after being aligned with some functional components, thereby improving the assembly efficiency and simplifying the production process of the upper cover. In addition, when the generator needs to be maintained, after the upper cover is removed, all the functional components of the generator are in a visible or operable state, which also facilitates the maintenance of the generator. In addition, since the upper cover does not interact with all the functional components, there are not many functional requirements for the upper cover, and it only serves as a covering function. Therefore, the strength requirements of the upper cover are not high, and the manufacturing cost of the upper cover is not high, which can reduce costs.

[0006] Preferably, an operation window is provided on one side of the upper cover, a cover plate is detachably connected to the operation window, and the operation components in the functional components are concentrated on the bottom plate and arranged on one side facing the operation window. In this solution, all the operation components are concentrated on one side to facilitate different operations.

[0007] Preferably, the housing is provided with an air inlet and an air outlet, and the functional components include an inverter, an air filter and a muffler, and the inverter, the air filter and the muffler are arranged along the air flow direction in the housing. This solution can ensure the cooling effect inside the generator.

[0008] Preferably, the air filter is arranged close to the operating window. This solution facilitates the maintenance of the air filter.

[0009] Preferably, a bracket is installed on the bottom plate, and the inverter is connected to the bracket. This solution facilitates the installation of the inverter.

[0010] Preferably, the base plate is located between the housing and the inverter.

[0011] Preferably, the functional component includes an oil pump, and the oil pump is located outside the base plate. This solution facilitates the repair of the oil pump.

[0012] The utility model has the following beneficial effects:

[0013] In the utility model, after all the functional components of the generator are arranged on the bottom plate, the upper cover only serves to cover all the functional components. There is no need for corresponding arrangements between the functional components or for some parts of the upper cover to be aligned with certain functional components before installation, thereby improving assembly efficiency and simplifying the production process of the upper cover. In addition, when the generator needs to be maintained, all the functional components of the generator are visible or operable after the upper cover is removed, which also facilitates the maintenance of the generator.
