DETAILED DESCRIPTION

[0021] The present invention is further described in detail below in conjunction with the embodiments: Example

[0022] like Figure 1-6 As shown, the utility model provides a vibration reduction and noise reduction system for a pump room, comprising a water pump and connecting pipes, and also comprising a floating platform for installing the water pump, an adjustable horizontal spring shock absorber is installed between the floating platform and the water pump, a pipe vibration reduction bracket is installed on the outside of the connecting pipe, and a pipe through-wall soft connection is arranged between the connecting pipe and the wall, a sound insulation cover is installed on the outside of the water pump, and a sound-absorbing ceiling is installed on the inside of the water pump room. In the water pump room, a floating platform and an adjustable horizontal spring shock absorber are first installed to reduce the vibration of the water pump, and then a sound insulation cover is installed on the water pump to reduce the noise while meeting the normal ventilation and heat dissipation requirements of the equipment, and then the water pump connecting pipe and the wall penetration are subjected to vibration isolation and soft connection treatment to reduce the vibration transmission of fluid dynamics, and a sound absorption structure is installed on the top of the water pump room to further reduce the reverberation noise.

[0023] Furthermore, the floating platform includes a casting formwork 102 installed on the ground, a concrete layer 101 is cast on the outside of the casting formwork 102, and a vibration-damping rubber pad 103 is installed on the bottom of the casting formwork 102. The cooperation of the above structures supports the entire platform structure, has good bearing capacity and stability, and ensures that the platform can withstand the weight of the water pump and the force generated during operation.

[0024] Furthermore, the soundproof enclosure includes a first steel column 201 installed on the outside of the water pump, sound-absorbing and insulating module panels 202 are installed between the first steel columns 201, and a muffler 203 is installed outside the sound-absorbing and insulating module panels 202, so that the water pump noise can be controlled within the soundproof enclosure.

[0025] Furthermore, a soundproof door 204 is installed outside the sound-absorbing and sound-insulating module panel 202, and a soundproof window 205 is installed between the first steel columns 201, which can effectively block the noise from propagating outward and ensure normal ventilation and heat dissipation of the water pump.

[0026] Furthermore, the pipeline vibration damping bracket includes a second steel column 402 installed on the ground, a rubber spring damper 401 is installed on the second steel column 402, and a clamp for fixing the connecting pipeline is installed on the rubber spring damper 401. Through the action of the rubber spring damper 401, vibration energy can be absorbed and dispersed when the pipeline vibrates, thereby significantly reducing the vibration amplitude and noise level of the pipeline.

[0027] Furthermore, a filling flexible material 501 is sleeved on the outer surface of the connecting pipe passing through the wall, and a sleeve 502 is installed on the outside of the filling flexible material 501. When the pipe needs to pass through the wall or structure, in order to avoid the stress and deformation caused by the direct hard connection, a soft connection method is used to connect the pipe and the wall or structure. Through the action of the filling flexible material 501, the displacement and vibration of the pipe caused by temperature changes, pressure changes or other factors can be absorbed, thereby protecting the pipe system from damage.

[0028] Furthermore, the sound-absorbing ceiling includes a T-shaped keel 603 installed on the top of the pump room, a metal perforated plate 601 is installed at one end of the T-shaped keel 603, and sound-absorbing cotton 602 is installed between the metal perforated plate 601 and the top of the pump room.
