Description

Technical Field

[0001] The utility model relates to the technical field of secondary water supply, in particular to the technical field of a water supply system for supplying water to multiple zones using a single tank, and specifically to an underground pipe bundle water supply system. Background Art

[0002] Secondary boosted water supply is mostly used in urban water supply. Since the height of buildings in cities is mostly between 50 meters and 150 meters, conventional water supply cannot reach such a high head. Therefore, secondary boosted water supply is required. The key to secondary boosted water supply is to stabilize the pressure supply to avoid the problem of high pressure at low flow rate and low pressure at high flow rate. There are two main factors to consider for stable secondary water supply. One is whether the storage capacity of the secondary water supply can meet the peak water demand of the water-using area; the other is stable pressure supply. The applicant has been committed to the research and development and practice of water supply systems for many years, and has continuously iterated the boosted water supply technology.

[0003] In real life, the demand for water supply in the water supply area is very large. During the peak water use period, the problem of insufficient storage capacity is very likely to occur. When the water from the municipal pipeline is not enough to make up for the actual water use, the storage capacity will be consumed. When the water in the storage capacity is exhausted, temporary water outage or low-flow water supply will occur. If the storage problem is solved by increasing the volume of the compensation tank, then the pressure bearing and installation of the compensation tank will bring new problems.

[0004] The applicant has developed a tube bundle storage technology that can effectively solve the pressure problem caused by the large size of the tank body. For details, see publication number CN114960842A, which uses an S-shaped folded elbow to replace a single tank body to solve the pressure problem. However, with the promotion of this technology, the applicant has found that when the installation site is severely limited but water supply is required to multiple areas, the tube bundle storage technology brings inconvenience to the installation of the system. For this reason, the applicant has proposed a corresponding matching method of one tank and one machine with publication number CN115787787A. This method can effectively solve the problem of limited installation site and scattered supply areas. The combination of multiple tanks and multiple machines can effectively meet the water supply needs of multiple areas.

[0005] Although the above solutions can solve the corresponding technical problems, they can hardly achieve perfect compatibility for different application scenarios. For this reason, the applicant's R&D team comprehensively considered the installation site limitations of the existing secondary water supply system, multi-area water supply, and the large fluctuation range of water consumption in the water-using areas, and once again upgraded the technology and proposed this application to replace the existing booster water supply system. Utility Model Content

[0006] In order to solve the problem that large-sized regulating and storage tanks occupy a large area and are difficult to install, and that small tanks have insufficient regulating and storage volumes, and that in the prior art, large-flow water supply will use multiple sets of booster water supply equipment, which makes the water wells scattered and difficult to maintain; the present application provides an underground pipe bundle water supply system, which can adaptively arrange different regulating and storage volumes according to actual water use scenarios, and at the same time, it can also expand the capacity later according to changes in water consumption in the water use area, which is conducive to transformation.

[0042] Embodiment 1:

[0043] See the instruction manual Figure 1-Figure 8 The buried pipe bundle water supply system shown includes a first regulating tank 2 connected to a municipal water pipe and having a negative pressure prevention mechanism. A boosting mechanism 3 is installed in the first regulating tank 2. The boosting mechanism 3 includes at least two independent boosting pump groups. The water outlet of any boosting pump group is provided with a water outlet well unit 6 for monitoring the water outlet status. The water outlet of the water outlet well unit 6 is connected to a water use area pipeline. A first water pipe is also provided at the bottom of the first regulating tank 2. A valve A71 is provided on the first water pipe, or the water outlet of at least one boosting pump group in the first regulating tank 2 is connected to a water use area pipeline or a drainage pipeline through a three-way valve 607 or a valve group. Any set of booster pump group includes at least one unit pump 301, and the valve group includes a shut-off valve 608 and a bypass valve 609. The shut-off valve 608 is installed on the water outlet branch pipe 610 of any unit pump 301, and the bypass valve 609 is installed on the water branch pipe 610 at a position between the shut-off valve 608 and the water outlet end of the unit pump 301, or the bypass valve (609) is installed on the water outlet branch pipe B (611) to control the drainage on / off.

[0044] Working principle description:

[0045] See the instruction manual Figure 2 As shown, the municipal water pipe is used as a water source to inject tap water into the first regulating tank 2. When the injection flow Q1 of the municipal water pipe is greater than the water outlet flow Q2 of the boosting mechanism 3, the water level in the first regulating tank 2 rises until it reaches the full water level; similarly, when the injection flow Q1 of the municipal water pipe is less than the water outlet flow Q2 of the boosting mechanism 3, the water level in the first regulating tank 2 drops until it drops to the lowest water level; the function of the first regulating tank 2 is to ensure that during peak water use and during continuous high-flow use, the water level in the first regulating tank 2 will not reach the lowest water level, resulting in insufficient water supply, thereby playing a role in regulating and storing. However, the peak flow in the water-using area is often uncertain. Generally speaking, in order to avoid insufficient peak water use, the margin coefficient of the regulating volume is used to expand the regulating volume, so that it is better to waste the regulating volume than to cause a water shortage due to insufficient regulating volume. In the prior art, multiple tanks are generally used for multi-area water supply. If several areas need to be supplied with water, several tanks are configured. Each tank has an independent boosting mechanism. In order to ensure the stability of the equipment, each boosting mechanism generally has a backup pump, so that normal water supply will not be affected after the working pump fails. However, such a setting will result in each tank being independent, and the storage volume cannot be shared. At the same time, the idle rate of the backup pump is also higher.

[0046] This embodiment uses a first regulating storage tank 2 to supply water to multiple independent booster pump groups at the same time. Each booster pump group can supply water to different areas, such as Figure 1 and Figure 2As shown, the boosting mechanism 3 includes three boosting pump groups, namely the first boosting pump group 31, the second boosting pump group 32 and the third boosting pump group 33, wherein any boosting pump group has two unit pumps 301 that are mutually standby, that is, the failure of one unit pump 301 of any boosting pump group will not affect the normal boosting water supply. The three boosting pump groups all share the regulating storage volume of the first regulating storage tank 2, and the pumps between the multiple boosting pump groups can be mutually standby. When the pumps are all working normally, there is no cross-supply of water between the boosting pump groups. When a water pump of a boosting pump group fails, the water pump in the boosting pump group of the adjacent group can be temporarily used as a standby pump, and only a pipeline with a controllable valve is needed to connect them in the middle; in the non-standby state, the controllable valve is in a normally closed state, and only when the standby pump needs to be activated, the controllable valve is opened, thereby temporarily replacing the faulty pump to avoid water outage. Since the multiple boosting pump groups are in a first regulating storage tank 2, the structure of mutually standby pumps is called possible. For example, in this embodiment, the multiple independent booster pump groups include two booster pump groups, namely booster pump group A and booster pump group B, each of which includes three water pumps, denoted as A1, A2, A3 and B1, B2, B3, wherein the A1 and / or A2 water pumps are connected to the water outlet of the booster pump group B through a controllable valve, and when any water pump in the booster pump group B fails, the booster pump group B can be supplied with water by opening the controllable valve; similarly, the B1 and / or B2 water pumps are connected to the water outlet of the booster pump group A through a controllable valve, and when any water pump in the booster pump group A fails, the booster pump group A can be supplied with water by opening the controllable valve. When the first regulating storage tank 2 needs to be cleaned, the sewage can be discharged from the first water pipe by opening the valve A71. Due to the underground installation, the outlet end of the valve A71 should be installed in a drainage well 7 at a lower position. The sewage generated by cleaning the pipeline is lifted to the ground through a water pump 72 installed in the drainage well 7 and discharged into the municipal pipe network.

[0047] The principle of using the booster pump group to drain water in this embodiment is as follows: when the first regulating storage tank 2 needs to be cleaned, the sewage generated after cleaning is discharged through at least one unit pump 301 provided with a three-way valve 607. Fig. 9 and Fig.10 As shown, when the water supply is normal, the three-way valve 607 is connected to the water area pipeline for normal pressurized water supply; when sewage needs to be discharged, the three-way valve 607 is connected to the drainage pipeline to discharge the sewage generated by cleaning to the ground or the municipal sewer network. Fig.11As shown, this embodiment also provides a method of using a valve group for sewage discharge, that is, when the water supply is normal, the bypass valve 609 on the outlet branch of the unit pump 301 used for drainage is closed, and the shut-off valve 608 is in a normally open state. After being pressurized, the drinking water enters the outlet well unit 6 through the outlet branch A610 and is sent to the water-using area pipeline; conversely, when it is necessary to flush the pipe bundle to discharge sewage, the bypass valve 609 is opened and the shut-off valve 608 is closed, so that the sewage is discharged from the bypass valve 609 to the ground or into the municipal rainwater pipe network. It is worth noting that the booster pump group includes at least one unit pump 301, which can be 1 or 2, such as Fig. 9 As shown; there can also be multiple units. When a booster pump group includes two or more unit pumps 301, then at least one unit pump 301 is a standby pump. There is at least one unit pump 301 for drainage. The specific number can be reasonably selected by technical personnel in this field based on the total number of unit pumps 301 in the actual booster pump group. As another way, the outlet branch pipe B611 is used as a pipeline specifically for drainage, and the bypass valve 609 is used to control the on-off of the outlet branch pipe B611. Of course, since the outlet branch pipe B is only used for drainage, the water flow can be direct or bypass. At this time, the bypass valve 609 plays a shut-off / on role. For details, see Fig.12 shown.

[0048] Embodiment 2:

[0049] This embodiment is based on the embodiment 1, in order to adapt to different water consumption areas, flexibly arrange the storage volume, and expand the capacity later on the basis of the water supply system that has been put into use. For details, please refer to the attached Figure 5-Figure 8 As shown, an expansion and regulation mechanism for increasing the regulation volume is also provided between the municipal water pipe and the first regulating tank 2, and the expansion and regulation mechanism includes one or a plurality of second regulating tanks 10 that are interconnected. The volume of the expansion and regulation mechanism is not limited, and the number of second regulating tanks 10 can be set according to the actual water consumption of the water-using area. Therefore, it can meet the water supply of areas with different water consumption, avoiding the problem that the single and fixed configuration of using regulating tanks of different sizes to adapt to the water consumption in the prior art cannot cope with the subsequent changes in water consumption. Any of the multiple second regulating tanks 10 can be further expanded and connected to other second regulating tanks 10, which is very convenient and conducive to subsequent upgrades and renovations. The connection method of the multiple second regulating tanks 10 that are interconnected included in the expansion and regulation mechanism includes any connection method of the multiple second regulating tanks 10, such as Figure 5 The series connection shown, Figure 6 The parallel connection method shown, Figure 7The mixed connection mode shown can share the regulating and storing volume as long as they can be connected to each other to form a communicating vessel structure, so as to achieve the purpose of capacity expansion. It is worth noting that any second regulating and storing tank 10 is also provided with a negative pressure prevention mechanism, such as a floating ball blocking mechanism. When the water level is low, the floating ball is separated from the vent under the action of gravity, so that air can enter the second regulating and storing tank 10 from the outside. When the water level reaches a high water level, the floating ball blocks the vent under the action of buoyancy, so that when the water level is low, the air cannot enter, resulting in negative pressure in the tank.

[0050] When installing the plurality of second regulating storage tanks 10, flexible steps can be performed according to the actual installation site. For example, the second regulating storage tanks 10 can be arranged and connected in the following manner:

[0051] Mode 1: The expansion storage mechanism includes a plurality of second storage tanks 10 connected in parallel, and any second storage tank 10 is connected to the first storage tank 2 through a valve. Figure 6 As shown, this connection mode can realize that all the second regulating storage tanks 10 or any second regulating storage tank 10 can be connected or disconnected with the first regulating storage tank 2. Figure 6 As shown, by controlling valve F13, valve G14 and valve H15, the corresponding second regulating storage tank 10 can be controlled to communicate with the first regulating storage tank 2. The normally open valve on the water inlet end pipeline of the second regulating storage tank 10 is not shown.

[0052] Method 2: See Figure 7 As shown, a mixed communication method can be adopted. At the same time, a valve can be set at one end or both ends of any second regulating storage tank 10. Figure 7 As shown, the first and fourth second regulating storage tanks 10 arranged from top to bottom are connected in parallel and are connected to the first regulating storage tank 2 through valves F13 and J, respectively. The second and third second regulating storage tanks 10 are connected by bypass. From the top, the second and third second regulating storage tanks 10 can be temporarily added to the regulating storage range by opening valves G14 and H15, and can be directly closed when not in use. Figure 7 A single second water pipe for sewage discharge is shown, which is discharged through valve D11.

[0053] In order to facilitate the cleaning of the second regulating storage tank 10, in this embodiment, at least one of the second regulating storage tanks 10 is provided with a second water pipe at the bottom, and a valve D11 is provided on the second water pipe. Figure 5-Figure 6 , Figure 8 As shown, after cleaning the second regulating tank 10, the sewage can be discharged by opening the valve D11.

[0054] Method 3: In order to further enhance the independence of the expansion and storage mechanism so that the normal pressurized water supply will not be affected when the expansion and storage mechanism is cleaned, this embodiment provides another optimized structure, see Figure 8 As shown, a third water pipe connected in parallel with the expansion and storage mechanism is also provided between the municipal water pipe and the first regulating tank 2, and a valve B8 is provided on the third water pipe. It is worth noting that Figure 8 The normally open valve on the water inlet well unit 5 and the water inlet end pipeline of any second regulating and storage tank 10 is not shown; when the second regulating and storage tank 10 needs to be cleaned, first close the normally open valve on the water inlet end of the second regulating and storage tank 10 so that the second regulating and storage tank 10 will no longer take in water. After cleaning, open the valve F13, valve G14 and valve H15 at the water outlet end of the second regulating and storage tank 10 to discharge the sewage through valve D11. Valve D11 can be installed on each second regulating and storage tank 10, or one or any one of them can be installed. When it is necessary to clean again, water is allowed to flow in by opening the normally open valve on the water inlet end pipeline, and the cleaning is repeated until the cleaning is completed. When cleaning one or more second regulating and storage tanks 10, this embodiment does not affect the continuous water supply. The water source of the municipal water pipe directly enters the first regulating and storage tank 2 through valve B8 for water supply. The water supply structure at this time is equivalent to Figure 1 or Figure 2 The structure shown.

[0055] Embodiment 3:

[0056] This embodiment provides another multi-scheme water supply structure, see Figure 5 As shown, a valve B8 is also provided between the municipal water pipe and the first regulating storage tank 2, and the valve B8 is connected to the municipal water pipe through a valve C9 and an expansion regulating storage mechanism, and the expansion regulating storage mechanism includes one or a plurality of second regulating storage tanks 10 that are interconnected, and the bottom of at least one second regulating storage tank 10 is connected to the valve A71 through a valve D11, and a valve E12 is also provided between the valve D11 and the valve A71. The water supply structure provided in this embodiment has multiple working modes:

[0057] The first type, when valve C9 and valve D11 are closed and valve B8 is opened, the structure is as follows Figure 2 As shown, the regulation is performed directly through the first regulating tank 2.

[0058] The second method is to close valve B8 and valve E12; open valve C9, valve D11, and valve A71, thereby providing a series expansion storage mechanism. The advantage of this method is that there will be no dead water in the blind area, and the water is always completely renewed. When this structure is cleaning the room, valve A71 can be closed and valve E12 can be opened to clean the expansion storage mechanism alone, and the normal water supply and storage of the first storage tank 2 will not be affected. Figure 5In the first regulating storage tank 2, three independent first water outlet well units 61, second water outlet well unit 62 and third water outlet well unit 63 are shown. Of course, more water outlet well units can be provided according to actual needs, and any water outlet well unit includes multiple booster pump groups, which are installed in the first regulating storage tank 2 through a water well detachably and tightly connected to the first regulating storage tank 2.

[0059] Embodiment 4:

[0060] In order to facilitate intelligent control, based on any of the above embodiments, see the attached Figure 1 As shown, a water inlet well unit 5 is also provided between the municipal water pipe and the first regulating storage tank 2, and the water inlet well unit 5 includes a gate valve 51, a water intake valve 52, a remote pressure gauge A53 and a flow limiting control valve 54; the water outlet well unit 6 includes a water quality detector 601, an ultraviolet disinfector 602, a pressure sensor 603, a remote pressure gauge B604, a pressure tank 605 and a flow meter 606. It also includes a control mechanism 1 for collecting information of the water inlet well unit 5 and the water outlet well unit 6 and controlling the opening / closing of any valve and the boosting mechanism 3. All valves in the entire water supply system can be controlled by the control mechanism 1, which is usually installed in a machine room for managing water supply.

[0061] The above description is only the preferred embodiment of the present application and is not intended to limit the present application. For those skilled in the art, the present application may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
