The noise in the equipment box can be reduced under the ventilation condition, and meanwhile, the air outlet is connected with the air exhaust duct instead of being directly communicated with the outside of the equipment box, so that the escape of the noise to the outside of the equipment box is reduced.
Further improvement, amortization air inlet mechanism includes the amortization base block, the amortization base block is made by amortization material, and inside sets up the wind channel.
In a further improvement, the air channel is folded to absorb more vibration in the air, so that the noise elimination effect can be improved.
In a further improvement, the silencing air inlet mechanism comprises a ventilation pipe, and the pipe wall of the ventilation pipe is made of silencing materials. The ventilation pipe can be bent to absorb more vibration in the air, so that the noise elimination effect can be improved.
In a further improvement, the silencing air inlet mechanisms are more than two and are arranged on two sides and/or the rear side of the lower part of the equipment box.
The equipment box is fixed on a building foundation platform and comprises a box wall, wherein a silencing material is attached to the interior of the box wall; the equipment box is provided with a damping platform, and the water pump and a motor thereof are arranged on the damping platform.
The improved damping platform comprises an installation foundation, wherein a spring damping piece is arranged on the installation foundation, a damping mounting plate is supported at the upper end of the spring damping piece, and the water pump and a motor of the water pump are installed on the damping mounting plate. The exhaust fan and the motor thereof are installed on the installation basis, and the spring damping piece is installed at the position, close to the edge, of the installation damping installation plate basis.

The silencing base block 11 is fixed with the outer wall of the equipment box in a bonding mode. Air can enter the interior of the equipment box through the air duct, and sound waves are absorbed by the sound-deadening material during the outward transmission.
The silencing air inlet mechanism 1 with the structure has a large volume occupied by the silencing base block and a good silencing effect.
As shown in fig. 4, another structural form of the silencing air intake mechanism is shown, and the silencing air intake mechanism 1 is composed of a group of silencing pipelines 13.

Air can enter the interior of the equipment box through the silencing pipe, and sound waves are absorbed by the silencing material in the process of being transmitted outwards.
The amortization air inlet mechanism 1 of this kind of structure owing to carry out the noise elimination through the noise elimination pipeline, and the amortization material of consumption is less, owing to through support frame and equipment box bolted connection, easily dismantles the change simultaneously.
Fig. 5 shows the internal structure of the equipment box 3 of the device, and the position of the exhaust fan is optimized by the equipment box 3. The exhaust fan and the motor thereof are changed from a top mounting mode to a shock absorption platform mounted on the water pump, and the structure of the shock absorption platform is improved in order to adapt to the mounting mode.
The equipment box 3 comprises a box wall 31, and sound attenuation materials are attached to the interior of the box wall 31. The equipment box 3 is provided with a damping platform 4, and the water pump and a motor thereof are arranged on the damping platform 4. The damping platform 4 comprises a mounting foundation 41, and the mounting foundation 41 is a concrete foundation.
