Description

Technical Field

[0001] The utility model relates to the technical field of generators, in particular to a super silent water-cooled generator set. Background Art

[0002] In a water-cooled generator set, a cooling water circuit is arranged in the generator, the cooling water inlet of which is connected to the outlet of a water pump, and the cooling water outlet of which is connected to a water storage tank. When the diesel engine operates, the cooling water circulates in the cooling water circuit, and can effectively cool the diesel engine.

[0003] Chinese Patent CN201620680852.4 discloses a housing of a super silent water-cooled generator set, in which the air inlet and the air inlet passage avoid the noise sources of the diesel engine and the generator, reducing noise. Since the motor and the diesel engine are in the same box, and the noise is mainly emitted by the diesel engine, and there is only one layer of board between the diesel engine and the outside world, the noise is still relatively large. Content of the Utility Model

[0004] To solve the technical problems in the background art, the utility model discloses a super silent water-cooled generator set.

[0005] The utility model provides a super silent water-cooled generator set, which comprises a housing, inside which an electric motor and a diesel engine are arranged, and an independent sound insulation cavity is also arranged in the housing;

[0006] The diesel engine is arranged inside the sound insulation cavity;

[0007] The electric motor is arranged outside the sound insulation cavity.

[0008] The sound insulation cavity is separately arranged in the housing, adding a sound insulation barrier between the diesel engine and the outside world, thereby reducing the sound frequency transmitted to the outside world when the diesel engine works and reducing the noise.

[0009] The specific structure of the sound insulation cavity is as follows: vertical and spaced first partition board and second partition board are arranged in the housing; the tops of the first partition board and the second partition board are connected by an upper board; both sides of the first partition board, the second partition board and the upper board are connected to the side board of the housing, and the lower ends are all connected to the bottom of the housing, so that the first partition board, the second partition board, the upper board, the side board of the housing and the bottom of the housing form the sound insulation cavity; the electric motor is located outside the first partition board; the diesel engine is located between the first partition board and the second partition board; the first partition board is provided with a notch; the electric motor passes through the notch and is connected to the diesel engine.

[0010] To facilitate the connection between the motor and the diesel engine, the notch needs to be opened large enough for workers to perform the connection operation. However, this will reduce the sound insulation effect of the sound insulation cavity. Based on this, a further improvement is as follows: the notch is in a U shape with the opening facing downwards; a baffle is connected to the lower end of the first partition board; the baffle blocks the opening position of the notch, thus forming a perforation, and the hole wall is in clearance fit with the motor. With this setting, first connect the motor and the diesel engine, and then install the baffle. This not only facilitates the assembly of the motor and the diesel engine, but also reduces the size of the perforation, ensuring the effective sound insulation effect of the sound insulation cavity.

[0011] Furthermore, the upper plate is provided with a V-shaped groove, and its opening faces the first partition board; the groove wall of the V-shaped groove extends upwards to form a first guiding plate in a V shape; the upper end of the first guiding plate is connected to the top plate of the housing; the housing includes a front side plate and a rear side plate arranged oppositely; both the front side plate and the rear side plate are provided with a plurality of through holes; the positions of the through holes are directly opposite to the first guiding plate. The setting of the first guiding plate forms two air outlet channels, thus increasing the flow area for the hot air to be discharged from the diesel engine. Moreover, the first guiding plate also separates the air inlet channel and the air outlet channel.

[0012] Furthermore, a mixing plate is also connected to the top of the first partition board; the mixing plate is composed of a bottom plate and an inclined plate forming an obtuse angle; the bottom plate is horizontally arranged and fixedly connected to the top of the first partition board; the inclined plate extends away from the diesel engine and extends obliquely upwards. The setting of the mixing plate enables the air to first flow to the connection part between the mixing plate and the first partition board during air intake, and then bypass the mixing plate and flow into the sound insulation cavity through the V-shaped groove for use by the diesel engine. In this way, not only the length of the air intake flow path of the diesel engine is extended, but also there are multiple bends in the air intake flow path, so that the sound is not easily transmitted out through the air intake flow path.

[0013] To further improve the sound insulation effect, specifically: sound insulation cotton is pasted on the inner walls of the sound insulation cavity; the gap between the perforation and the motor is also sealed with sound insulation cotton. Description of the Drawings

Specific implementation manner

[0021] Now, the present utility model will be further described in detail with reference to the accompanying drawings. These drawings are all simplified schematic diagrams, only illustrating the basic structure of the present utility model in a schematic manner, so they only show the components related to the present utility model.

[0022] As Figures 1-3 shown, the present utility model discloses a super silent water-cooled generator set, including a housing 1. The housing 1 is provided with a cuboid base, and a fuel tank is installed in the base for containing diesel for use by the diesel engine.

[0023] The four sides of the upper end of the base are connected with upwardly extending front side plate 11, rear side plate 12, left side plate 14 and right side plate 15. The top of the side plates is closed by a connected top plate.

[0024] The housing 1 is also connected with vertically and spaced first partition board 4 and second partition board 5. The top of them is connected by an upper plate 6, the sides are connected with the front side plate 11 and the rear side plate 12, and the bottom is connected with the base, so that an independent sound insulation cavity is formed between the first partition board 4, the second partition board 5, the upper plate 6, the front side plate 11, the rear side plate 12 and the base. The diesel engine is installed in the sound insulation cavity, and the motor is installed outside the first partition board 4, between the first partition board 4 and the left side plate 14.

[0025] As Figure 5 shown, the first partition board 4 is provided with a notch 41 opening downward, and the head of the motor passes through the notch 41 to be connected with the diesel engine. The second partition board 5 is provided with a plug-in slot, and the tail of the diesel engine, the part provided with a fan, passes through the plug-in slot and is arranged between the second partition board 5 and the right side plate 15.

[0026] As Figure 4 shown, the lower end of the first partition board 4 is connected with a baffle 7; the baffle 7 blocks the opening position of the notch 41, thus forming a through hole, and the hole wall is in clearance fit with the motor. With such a setting, first connect the motor with the diesel engine, and then install the baffle 7, which not only facilitates the assembly of the motor and the diesel engine, but also reduces the size of the through hole, ensuring the effective sound insulation effect of the sound insulation cavity.

[0027] The upper plate 6 is provided with a V-shaped groove 61, whose opening faces the first partition; the groove walls of the V-shaped groove 61 extend upward to form a first guide plate 9 in the shape of a V, and the upper end of the first guide plate 9 is connected to the top plate of the housing. Both the front side plate 11 and the rear side plate 12 are provided with a plurality of through holes 13; the positions of the through holes 13 are directly opposite to the first guide plate 9. The setting of the first guide plate 9 forms two air outlet channels, thereby increasing the flow area for the hot air to be discharged from the diesel engine. The top of the cavity formed by the second partition 5 and the right side plate 15 is connected with an inclined second guide plate 2, whose low end points to the right side plate 15 and the high end points to the second partition 5. The hot air blown by the fan flows out to the outside from the through holes 13 under the guiding action of the second guide plate 2 and the first guide plate 4 in sequence. At the same time, the first guide plate 4 also separates the air inlet channel and the air outlet channel of the diesel engine.

[0028] The top of the first partition 4 is also connected with a mixing plate 10; the mixing plate 10 is composed of a bottom plate 101 and an inclined plate 102 forming an obtuse angle; the bottom plate 101 is horizontally arranged and fixedly connected to the top of the first partition 4; the inclined plate 102 extends away from the diesel engine and extends obliquely upward. The setting of the mixing plate 10 enables the air to first flow to the connection between the mixing plate 10 and the first partition 4 during air intake, and then bypass the mixing plate 10 and flow into the sound insulation cavity through the V-shaped groove 61 for use by the diesel engine. In this way, not only the length of the air intake flow path of the diesel engine is extended, but also there are multiple bends in the air intake flow path, so that the sound is not easily transmitted out from the air intake flow path.

[0029] The sound insulation cavity is separately arranged in the housing 1, adding a sound insulation barrier between the diesel engine and the outside, thereby reducing the sound frequency transmitted to the outside during the operation of the diesel engine and reducing the noise. Moreover, in order to further improve the sound insulation effect, sound-absorbing cotton is pasted on the side surfaces of the sound insulation cavity, the gap between the perforation and the motor is blocked with sound-absorbing cotton, and the gap between the insertion slot on the second partition 5 and the diesel engine is also blocked with sound-absorbing cotton.

[0030] Inspired by the above ideal embodiments of the present invention, through the above description, relevant staff can completely make various changes and modifications within the scope not deviating from the technical idea of this invention. The technical scope of this invention is not limited to the content in the specification, and its technical scope must be determined according to the scope of the claims.
