As a result, the water supply equipment needs to be continuously improved. The secondary water supply adopted in the prior art refers to that units or individuals store, pressurize the urban public water supply or self-built water supply facilities and then supply water to users through pipelines. For high-rise buildings, due to the lack of pressure in the municipal water supply pipeline, it is usually necessary to perform secondary pressurization on the municipal water supply so that tap water can reach high-rise buildings and be supplied to high-rise users. In the prior art, during the peak water consumption period of users, it is often impossible to reach the height or flow rate of user water consumption due to insufficient pressure. In addition, the vertical water pump unit used for high-rise buildings in the prior art has a temperature protection function, that is, when the temperature reaches a certain value during its operation, it will automatically cut off the power, so that during the peak water consumption period of users, the water consumption flow rate of high-rise users cannot meet the demand.

[0003] In order to solve the above problems, a water supply device with a regulating system is proposed in the present invention. Summary of the Invention

[0013] Beneficial effects:

[0014] 1. The invention solves the problem that the water height or flow rate cannot be reached due to insufficient pressure.

Detailed implementation manners

[0025] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0026] Next, in conjunction with the attached Figures 1-6 And embodiments, the present invention will be further described:

[0027] In this embodiment, as Figure 1As shown in the figure, a water supply device with an adjustment system includes a bottom plate 1, characterized in that: the bottom plate 1 is provided with a plurality of water supply unit modules 2, an inlet pipe 12 is installed on the water supply unit module 2, one side of the plurality of water supply unit modules 2 is connected to the inlet pipe 12, the end of the inlet pipe 12 is connected to a constant pressure tank 14, the other side of the plurality of water supply unit modules 2 is connected to an outlet pipe 13, a diaphragm pressure tank 10 and a pressure sensor 11 are installed on the outlet pipe 13, the end of the outlet pipe 13 is connected to the water supply port of the user terminal, and the constant pressure tank 14, the water supply unit module 2, the diaphragm pressure tank 10 and the pressure sensor 11 are all connected to a variable frequency control cabinet 15 fixedly arranged on the bottom plate 1 through a PLC system;

[0028] Further, when the water supply of the present invention starts, the pressure of the water supply is detected by the pressure sensor 11. When the pressure is insufficient, the pressure sensor 11 transmits the pressure signal to the variable frequency control cabinet 15, and the variable frequency control cabinet 15 controls the constant pressure tank 14 to keep the pressure in the constant pressure tank 14 constant, and then water supply is carried out by opening a plurality of water supply unit modules 2. During the peak water consumption period, the variable frequency control cabinet 15 controls the diaphragm pressure tank 10 to start. When the water with pressure from the outside fills the inner bladder of the diaphragm pressure tank 10, the air sealed in the tank is compressed. According to Boyle's law of gases, the volume of the gas becomes smaller after being compressed, and the pressure increases to store energy. The expansion of the compressed gas can press the water in the rubber diaphragm out of the tank to further increase the water pressure and flow rate at the pressure sensor 11, so as to ensure sufficient flow rate during the peak water consumption period on high floors. During the low peak water consumption period at night, when the pressure at the pressure sensor 11 is relatively high, the variable frequency control cabinet 15 can control the water supply unit module 2 to be turned off and use one water supply unit module 2 for water supply, or control the pressure in the constant pressure tank 14 to keep the water supply constant.

[0029] The present invention is a new type of environmentally friendly and energy-saving professional device specially developed and designed to solve the problem that due to insufficient pressure, the water cannot reach the height or flow rate required by users. It is composed of a water supply unit module 2, a variable frequency control cabinet 15, a diaphragm pressure tank 10, a pressure sensor 11 and some accessories. It automatically adjusts the number of operating water pumps according to the change of user water consumption, always keeps the system pressure constant, and makes the water pumps always work in the high-efficiency area, which not only ensures constant pressure water supply for users but also saves electric energy.

[0030] As a preferred embodiment, refer to as Figures 1-2As shown, the water supply unit module 2 includes a water pump unit 25. The water pump unit 25 is fixedly connected to the bottom plate 1 through a plurality of tension bolts 251. A plurality of support columns 20 are arranged in a four-corner array at the water pump unit 25. A ring 22 is rotatably sleeved on the water pump unit 25. A shock absorption assembly 21 is provided between each support column 20 and the ring 22. Further, since the water pump unit 25 is vertically arranged on the bottom plate 1, the water supply pump below it is driven to supply water by the rotation of the upper motor, so that the water pump unit 25 generates a certain amplitude of swing and vibration during operation. In order to avoid the rapid rotation of the water pump unit 25 during the peak water use period, resulting in a swinging force and an increase in its temperature, the shock absorption assembly 21 is provided to reduce the swing and vibration of the water pump unit 25 during operation, and to prevent the tension bolts 251 from loosening during long-term operation.

[0031] As a preferred embodiment, refer to Figure 2 As shown, the shock absorption assembly 21 includes a sleeve 211, a connecting block 212 and a piston rod 213. One end of the piston rod 213 is slidably connected to the sleeve 211. Preferably, the piston rod 213 is slidably and sealingly connected to the sleeve 211. The other end of the piston rod 213 is fixedly connected to the connecting block 212. The sleeve 211 is ball-connected to a support column 20 through a ball 203, and the sleeve 211 is also connected to a support column 20 through a plurality of springs 204. The connecting block 212 is slidably connected to the ring 22. Further, when the water pump unit 25 is in an operating state, the vibration generated by it is transmitted to the piston rod 213 through the connecting block 212. The piston rod 213 is slidably and sealingly connected to the sleeve 211, so that the vibration of the water pump unit 25 is weakened. At the same time, the swinging force generated during the operation of the water pump unit 25 is transmitted to the sleeve 211 through the connecting block 212 and the piston rod 213. Then, the sleeve 211 weakens the swing generated during the operation of the water pump unit 25 through a plurality of springs 204 connected to the support column 20. By this design method, it is possible to prevent the swinging force and vibration generated during the operation of the water pump unit 25 from loosening the connection between the tension bolts 251 and the bottom plate 1. Further, by weakening the vibration of the water pump unit 25, the noise decibel generated during the operation of the water pump unit 25 is reduced to a certain extent.

[0032] As a preferred embodiment, refer to Figures 2-4As shown, a sliding cavity 210 is provided inside the sleeve 211. A piston rod 213 is slidably arranged inside the sliding cavity 210. A through hole 214 is provided inside the piston rod 213. One side of the through hole 214 communicates with the sliding cavity 210, and a water spray head 215 is fixedly arranged on the other side. The water spray head 215 opens when the pressure increases and closes when the pressure decreases. By setting the water spray head 215, the vibration force generated when the water pump unit 25 operates can be transmitted through the sliding connection between the piston rod 213 and the sliding cavity 210, causing the piston rod 213 to move back and forth continuously inside the sliding cavity 210, resulting in a change in the volume inside the sliding cavity 210. Thus, the vibration force of the water pump unit 25 is converted into a change in the pressure difference inside the sliding cavity 210. When the pressure inside the sliding cavity 210 increases, the water spray head 215 sprays the water inside the sliding cavity 210 into the external space, and the water spray head 215 is used to utilize this pressure difference.

[0033] In this embodiment, referring to Figure 1 and Figure 5 As shown, a communication hole 217 is formed on one inner wall of the sliding cavity 210. A water pipe 24 is connected to each communication hole 217. The end of the water pipe 24 communicates with the constant pressure tank 14. Further, because the sliding cavity 210 is communicated with the constant pressure tank 14 by setting the water pipe 24, and a constant pressure is maintained inside the constant pressure tank 14, when the piston rod 213 is vibrated by the water pump unit 25, the piston rod 213 continuously moves inside the sliding cavity 210. At this time, the water inside the constant pressure tank 14 is continuously sprayed into the external space through the water spray head 215 to cool the water pump unit 25.

[0034] In this embodiment, referring to Figures 3-4 As shown, an installation cavity 2120 is provided inside the connection block 212. A rotating shaft 216 is rotatably arranged inside the installation cavity 2120. A fan blade 2160 is provided on the rotating shaft 216, and one side of a fan blade of the fan blade 2160 away from the center line of the rotating shaft 216 is in the same cross-section as the water spray head 215. Further, when the water sprayed by the water spray head 215 impacts the fan blade 2160, the fan blade 2160 rotates counterclockwise around the rotating shaft 216, and the water sprayed by the water spray head 215 enters the ring 22 as the fan blade 2160 rotates.

[0035] As a preferred embodiment, referring to Figure 6As shown, an annular groove 220 is provided on the ring 22, and the annular groove 220 is connected to the placement cavity 2120. A plurality of partitions 221 are evenly arranged on the inner circumference of the annular groove 220. A water storage cavity 2201 is provided on the inner wall of the partition 221. A plurality of groups of water outlet holes 2202 are arranged on the inner circumference of the water storage cavity 2201. The water outlet holes 2202 are connected to the outside. Further, water flows into the annular groove 220 through the rotation of the fan blade 2160, and then flows into the water storage cavity 2 201, flows out of the water storage chamber 2201 to the outside and falls onto the heat sink of the water pump unit 25 to dissipate heat for the water pump unit 25. At the same time, the rotation of the fan blade 2160 moves the partition 221, and the partition 221 causes the ring 22 to rotate clockwise around the water pump unit 25, so that the water sprayed by the sprinkler head 215 flows evenly to the surface of the heat sink of the water pump unit 25, dissipating heat for the water pump unit 25 evenly, further improving the heat dissipation effect of the shock absorbing component 21.

[0036] As a preferred embodiment, refer to Figure 2 As shown, a plurality of exhaust plates 23 are evenly arranged on the circumference below the circular ring 22. The exhaust plates 23 are preferably made of sound-proof cotton material. As an optional embodiment, a plurality of irregular holes can be arranged on the exhaust plates 23, so that the rotation of the circular ring 22 drives the exhaust plates 23 to rotate, and the air around the water pump unit 25 can be exchanged with the outside air in time, thereby strengthening the heat dissipation of the water pump unit 25. At the same time, the rotation of the exhaust plates 23 can accelerate the drying of the water flowing into the heat sink of the water pump unit 25, thereby improving the heat dissipation effect of the shock absorbing assembly 21, and the irregular holes arranged on the exhaust plates 23 can absorb part of the noise generated when the water pump unit 25 is working.

[0037] The embodiments of the present invention disclose preferred embodiments, but are not limited thereto. A person skilled in the art can easily understand the spirit of the present invention based on the above embodiments and make different extensions and changes. However, as long as they do not deviate from the spirit of the present invention, they are all within the protection scope of the present invention.
