Description

Low-noise generator set with improved motor rear cover

Technical Field

The utility model belongs to the technical field of generating set, concretely relates to low noise generating set of motor rear cover improvement.

Background

At present, two types of units exist in the industry of the general gasoline generating set, one is an open type unit and the other is a closed type unit.

The existing closed type unit has the advantages of low noise, poor heat dissipation effect and high power loss. The motor back cover of the traditional low-noise generator set is shown in figure 1, the assembled structure is shown in figure 2, the front end 41 'of the traditional motor back cover 4' is assembled on the generator 31', the air inlet 42' of the traditional motor back cover is arranged in a low-noise generator set cavity, and because the temperature in the cavity is high, the temperature of the generator is also increased after air inlet, and a vicious circle is formed to cause the performance of the generator set to be reduced.

Disclosure of Invention

The utility model aims to solve the technical problem that a low noise generating set of motor back shroud improvement is provided, this motor back shroud air intake outside low noise unit cavity, what admit air is outside natural air, has reduced the temperature of generator.

The utility model discloses a realize like this:

a low noise generator set with an improved motor back cover, comprising: the engine and generator assembly is arranged on the base and is positioned in the shell;

the rear end of the generator of the engine and generator assembly is provided with a motor rear cover,

the front end of the motor rear cover is assembled at the rear end of the generator, the bottom of the motor rear cover extends to the base, a first air inlet is arranged at the bottom of the motor rear cover,

and a second air inlet is formed in the base corresponding to the first air inlet.

Furthermore, an air box component is also arranged in the shell; the air box component is arranged on the base in the shell; and a silencer is also arranged inside the air box part.

The utility model has the advantages that: 1. the structure is simple and the assembly is convenient; 2. the universality is high, and the applicability is strong; 3. because the air is the natural air outside, the temperature is much lower than the temperature in the unit cavity, so the temperature of the generator is reduced, and the performance of the unit is naturally improved.

Drawings

The invention will be further described with reference to the following examples with reference to the accompanying drawings.

Fig. 1 is a schematic structural diagram of a rear cover of a motor in the prior art.

Fig. 2 is a schematic view of a structure in which a rear cover of a motor of the related art is assembled to a generator.

Fig. 3 is a schematic structural diagram of the motor rear cover of the present invention.

Fig. 4 is a schematic structural diagram of the present invention (with part of the outer shell removed).

Detailed Description

As shown in fig. 3 and 4, a low noise generator set with an improved motor rear cover includes: the engine and generator assembly comprises a base 1, a shell 2 and an engine and generator assembly 3, wherein the shell 2 is arranged on the base 1 in an enclosing mode, and the engine and generator assembly 3 is arranged on the base 1 and located in the shell 2.

A motor rear cover 4 is mounted on the rear end of the generator 31 of the engine and generator assembly 3.

The front end 41 of the motor rear cover 4 is assembled at the rear end of the generator 31, the bottom of the motor rear cover 4 extends to the base 1, the bottom of the motor rear cover 4 is provided with a first air inlet 42, and the base 1 corresponding to the first air inlet 42 is provided with a second air inlet 11. The external natural air enters the first air inlet 42 from the second air inlet 11 on the base 1 to reach the generator 31. Establish in the unit intracavity for the air intake 42 'of the motor back shroud 4' among the prior art, the utility model discloses because what admit air is outside natural air, the temperature has been reduced a lot.

An air box part 5 is also arranged in the shell 2; the air box part 5 is arranged on the base 1 in the shell 2; a silencer (not shown) is also provided inside the bellows part 5.

The utility model has simple structure and convenient assembly; the universality is high, and the applicability is strong; the external natural air enters the first air inlet 42 from the second air inlet 11 on the base 1 to reach the generator 31, and the temperature of the generator 31 is reduced and the performance of the generator is naturally improved because the external natural air is introduced and is much lower than the temperature in the generator set cavity.

The above embodiments and drawings are not intended to limit the form and style of the present invention, and any suitable changes or modifications made by those skilled in the art should not be construed as departing from the scope of the present invention.
