The side walls 3 are generally 4-sided and enclose a cuboid chamber body 1.

A diesel generator foundation 6 is arranged on the ground 4, the diesel generator foundation 6 is a concrete foundation and is obtained through pouring, and a diesel generator 5 is installed on the diesel generator foundation 6. The upper surface of the diesel generator foundation 6 is 30cm higher than the ground 4 so as to achieve the waterproof effect. Similarly, the base should be suitably elevated above the ground 4 when other electrical facilities are installed.

When the diesel generator 5 operates, the ground 4 is driven to vibrate, vibration waves are transmitted to the electric facilities along the ground 4, and other electric facilities vibrate, and in order to weaken the vibration, vibration isolation grooves 7 are arranged on the periphery of the diesel generator foundation 6, and the vibration isolation grooves 7 extend downwards to the position below the ground 4. The vibration isolation groove 7 is arranged on the ground 4 and is in a closed ring shape and surrounds the diesel generator foundation 6. The ground 4 is required to be used as a medium for transmitting the vibration waves, and the vibration isolation grooves 7 remove the transmission medium, so that the vibration waves can be cut off, the vibration can be blocked, and the influence of the operation of the diesel generator 5 on other electric facilities can be prevented.

In addition, a damping device 13 can be arranged between the diesel generator 5 and the diesel generator base 6, and the damping device 13 can adopt an elastic damping piece such as a spring and the like to play a role in damping vibration.

The diesel generator 5 is connected with a smoke exhaust pipe 8, and a silencer 9 is arranged on the smoke exhaust pipe 8. The diesel generator 5 generally uses fuel oil as fuel, and generates a large amount of smoke after combustion, so the smoke is discharged through the smoke discharge pipe 8, and the outlet end of the smoke discharge pipe 8 reaches the highest point of an above-ground building, so that the discharged smoke is prevented from causing adverse effects on above-ground residents. The silencer 9 is a conventional silencer, so that noise can be reduced, and noise pollution can be reduced. In order to keep the silencer 9 stable, the silencer 9 may be mounted to the top floor 2 by brackets 15.

An exhaust shaft 10 is arranged at one side of the diesel generator 5, and an exhaust tube 11 of the diesel generator 5 is communicated with the exhaust shaft 10. The diesel generator 5 needs to be exhausted when in operation, the temperature of the exhausted gas is generally higher than the room temperature, and if the gas is directly exhausted into the chamber body 1, the temperature in the chamber body 1 can be rapidly increased, and the performance of the diesel generator 5 and other electric facilities is affected. Therefore, the utility model discloses set up exhaust shaft 10, a lateral wall of exhaust shaft 10 can be a side wall 3 of room body 1. The air discharge shaft 10 is communicated with an external space, and can discharge hot air. The chamber body 1 is required to maintain good ventilation so that air is circulated for intake-exhaust.

In order to avoid that the air exhausting shaft 10 occupies a large building space, the upper port of the air exhausting shaft 10 extends to the upper part of the top floor slab 2, namely, the upper port of the air exhausting shaft 10 is positioned in the space of the first floor, and at the moment, the air exhausting shaft 10 mainly occupies the space of the second floor, occupies part of the space of the first floor, and does not occupy the space of other floors. The upper port of the air exhaust shaft 10 is provided with a top cover 18, and the top cover 18 can be a metal cover or a concrete cover, so that the upper port of the air exhaust shaft 10 is sealed, and sundries and the like are prevented from falling into the air exhaust shaft 10. The side wall of the air exhaust well 10 above the top floor 2 is provided with an air exhaust hole 19, the air exhausted by the diesel generator 5 can be exhausted through the air exhaust hole 19, and in order to prevent sundries from entering the air exhaust well 10 through the air exhaust hole 19, a shutter 20 is arranged in the air exhaust hole 19.

In order to further improve the noise reduction effect, the lower surface of the top floor 2 and the inner side of the side wall 3, which is the side facing the inside of the chamber body 1, are provided with sound insulation layers 12. The soundproof layer 12 is made of a conventional soundproof material such as sound-absorbing cotton. The thickness of the soundproof layer 12 is about 100 mm.

The condition that machine oil or diesel oil were revealed can appear in diesel generator 5, if machine oil or diesel oil flow after revealing at will, can pollute other electric power facilities, cause the conflagration even, consequently, the utility model discloses be provided with annular fender oil groove 14 at the upper surface edge of diesel generator basis 6. The section of oil blocking groove 14 is rectangle or semi-circular, and diesel generator basis 6 upper surface is the rectangle generally, and oil blocking groove 14 sets up four limits departments of rectangle and interconnect, forms the confined annular, surrounds diesel generator 5, and when diesel generator 5 oil leak, machine oil or diesel oil can flow to oil blocking groove 14 in, and can not flow outside diesel generator basis 6, prevent that the machine oil or the diesel oil that reveal from flowing to other electric power facilities. The groove bottom of the oil retaining groove 14 can be obliquely arranged, an oil discharge hole is arranged at the lower position of the groove bottom, the oil discharge hole extends to the side wall of the diesel generator base 6 from the oil retaining groove 14, an oil collecting tank is arranged at the hole opening of the outer end of the oil discharge hole and used for collecting leaked engine oil or diesel oil, and the oil retaining groove 14 can not contain all leaked oil when the oil leakage amount is large.

Because the vibration of the diesel generator 5 can drive the smoke exhaust pipe 8 and the exhaust cylinder 11 to vibrate, the smoke exhaust pipe 8 and the exhaust cylinder 11 are quickly loosened, therefore, the smoke exhaust pipe 8 is connected with the smoke exhaust port of the diesel generator 5 through the first flexible connecting piece 16, and the exhaust cylinder 11 is connected with the air exhaust port of the diesel generator 5 through the second flexible connecting piece 17. The first flexible connecting piece 16 and the second flexible connecting piece 17 can adopt corrugated pipes which can deform and can deform along with the vibration of the diesel generator 5, so that most of vibration is absorbed, and the influence of the vibration on the smoke exhaust pipe 8 and the exhaust cylinder 11 is reduced.

The diesel generator 5 and other electric facilities are also connected with a grounding device, the grounding device comprises a plurality of grounding poles vertically arranged below the ground 4 and a horizontal cross bar connected with two adjacent grounding poles, and the grounding poles and the horizontal cross bar can adopt galvanized steel sectional materials to form a grounding network to play a role in grounding protection. The ground resistance of the grounding device should not be higher than 1 omega.

When emergency power failure occurs, the diesel generator 5 is started to supply power to other electric facilities, and outside air enters the chamber body 1 through the ventilation facility. The gas passing through the diesel generator 5 is discharged to the first floor space through the second flexible connecting piece 17, the exhaust tube 11, the exhaust shaft 10 and the exhaust hole 19 in sequence, although the temperature of the discharged gas is relatively high, the exhaust shaft 10 can be arranged at a position which is difficult to reach or rarely reached by residents, and the influence on the activities of the residents is reduced.
