[0024] See also Figures 1-4 This utility model provides a fully variable frequency controlled constant pressure water supply device. The fully variable frequency controlled constant pressure water supply device of this application can be equipped with a conventional variable frequency controller, including a base 1, a plurality of shock-absorbing devices 2 on the base 1, a shock-absorbing support plate 3 on the plurality of shock-absorbing devices 2, a pressure stabilizing tank 4 fixedly connected to the shock-absorbing support plate 3, a pressure stabilizing pipe 5 on the pressure stabilizing tank 4, and a water outlet pipe 6 connected to one end of the pressure stabilizing pipe 5 facing away from the pressure stabilizing tank 4. A pump body unit 7 is vertically mounted on the shock-absorbing support plate 3, and the pump body unit 7 is connected to the water outlet pipe 6. In this application, the pump body unit 7 and the pressure stabilizing tank 4 can constitute an important structure of the conventional variable frequency constant pressure water supply device, and valves and pressure gauges should be reasonably installed on each pipeline of the water supply device for use.

[0025] A fixed support rod 15 is fixedly connected to the base 1. The shock absorption device 2 includes a spring damper, which is fixedly connected to the fixed support rod 15. The shock absorption plate 3 is fixedly connected to the spring damper. The spring damper is a combination of a spring and a damper. The spring can be used to buffer the working vibration of the pump body unit 7, while the damper can reduce the amplitude caused by buffering.

[0026] An assembly frame 16 is fixedly connected to the shock-absorbing support plate 3. The pump body unit 7 includes at least three variable frequency water pumps 71 fixedly connected to the assembly frame 16, a multi-port water inlet pipe 72 fixedly connected to the water inlet end of the three variable frequency water pumps 71, and a pump pipe 73 fixedly connected to the water outlet end of each variable frequency water pump 71. The pump pipe 73 is connected to the water outlet pipe 6.

[0027] A housing is installed on the shock-absorbing support plate 3, and a water outlet pipe 6 is fixedly inserted through the housing. Sound insulation modules are installed on the housing and the shock-absorbing support plate 3. A pair of ventilation and sound-absorbing components 13 are installed on the housing, and a heat dissipation device is installed on one of the ventilation and sound-absorbing components 13.

[0028] The housing includes an outer shell 8 fixedly connected to the shock-absorbing support plate 3 and a cover 9 connected to the outer shell 8 by a hinge. The outer shell 8 is located on the outside of the pump unit 7. The outer shell 8 has an inspection port, which corresponds to the cover 9. In this application, the number of inspection ports can be set according to the maintenance position requirements of the full frequency conversion control constant pressure water supply equipment, and the number of cover 9 should be set synchronously with the number of inspection ports.

[0029] It is worth noting that since the technical problem to be solved in this application is the vibration and noise of the pump body unit 7, the outer shell 8 on the shock-absorbing plate 3 can be installed on the outside of the pump body unit 7.

[0030] The sound insulation module includes a sound insulation cotton layer 10 fixedly connected to the inner wall of the outer shell 8, a sound insulation cotton layer 2 11 fixedly connected to the upper surface of the shock-absorbing support plate 3, and a sound insulation cotton layer 3 12 fixedly connected to the inner side of the cover 9. The sound insulation cotton layer 3 12 on the cover 9 can achieve a sound insulation effect that can be opened and closed. While meeting the sound insulation requirements of the cover 9, it can facilitate the use of the maintenance port. By setting the sound insulation cotton layer 10, the sound insulation cotton layer 2 11 and the sound insulation cotton layer 3 12 on the outside of the pump body unit 7, the pump body unit 7 can be covered with sound insulation on all four sides. By utilizing the functional characteristics of the sound insulation cotton material, the transmission of noise from the variable frequency water pump 71 in the pump body unit 7 can be suppressed to the maximum extent.

[0031] The ventilation and noise reduction assembly 13 includes a ventilation hood 131 fixedly connected to the inner wall of the outer casing 8, a plurality of noise reduction pipes 132 fixedly connected to the ventilation hood 131, and a sound-absorbing cotton layer 133 fixedly connected to the inner wall of each noise reduction pipe 132. The noise reduction pipes 132 are fixedly installed through the outer casing 8, and the sound-absorbing cotton layer 133 can be made into a hollow cylindrical structure, which can facilitate the sound absorption treatment of the noise of the variable frequency water pump 71 inside the outer casing 8 during the transmission process.

[0032] The heat dissipation device includes a heat dissipation fan 14, which is fixedly connected to one end of one of the ventilation hoods 131.

[0033] Specifically, when the housing structure is encased on the pump unit 7 for noise reduction, in order to ensure the heat dissipation requirements of the variable frequency water pump 71, the cooling fan 14 is used to accelerate the air circulation inside the housing 8, thus achieving air cooling for the variable frequency water pump 71. In addition, to prevent the noise of the pump unit 7 from propagating outward due to the heat dissipation operation of the cooling fan 14, the silencing pipe 132 and the sound-absorbing cotton layer 133 are used to ventilate and silence the air inlet and outlet positions, thereby reducing the frequency of noise propagation.
