[0019] See appendix Figure 1-3 As shown, this utility model provides an integrated secondary water supply device including a cabinet 100, at least one centrifugal pump 1, a pressure stabilizing tank 2, a first transfer pipe 3, an inlet main pipe 5, an outlet main pipe 6, and a pressure tank 4.

[0020] Cabinet 100 has internal space.

[0021] Optionally, the cabinet 100 is a cuboid, with opposite top and bottom walls, two opposite side walls, and two opposite cabinet doors 101, the top wall, bottom wall, two side walls, and two cabinet doors 101 enclosing an internal space.

[0022] Centrifugal pump 1 has a connected inlet and outlet, which are located in the internal space and connected to the bottom wall of cabinet 100.

[0023] Optionally, the connection between the centrifugal pump 1 and the bottom wall of the cabinet 100 can be a detachable and fixed connection between the centrifugal pump 1 and the bottom wall of the cabinet 100.

[0024] The number of centrifugal pumps 1 can be set according to requirements and the volume of cabinet 100. In order to support rapid hoisting and mobile deployment, the number of centrifugal pumps 1 can be one, two or three, preferably three.

[0025] The number of centrifugal pumps 1 is greater than one, in order to have backups and prevent the device from failing to supply water effectively if one centrifugal pump 1 fails to work properly.

[0026] The pressure stabilizing tank 2 has a connected inlet and outlet, which is located in the internal space and connected to one side wall of the cabinet 100.

[0027] Optionally, the connection between the pressure stabilizing tank 2 and one side wall of the cabinet 100 can be a detachable and fixed connection.

[0028] The first adapter pipe 3 has a connected inlet end and at least one outlet end. The inlet end of the first adapter pipe 3 is connected to the outlet of the pressure stabilizing tank 2. Each outlet end of the first adapter pipe 3 is connected to the inlet of a centrifugal pump 1.

[0029] It should be noted that the number of outlet ends of the first adapter pipe 3 is consistent with the number of centrifugal pumps 1.

[0030] The main water inlet pipe 5 has a connected inlet end and an outlet end, and the outlet end of the main water inlet pipe 5 is connected to the inlet of the pressure stabilizing tank 2.

[0031] Optionally, the inlet end of the main water inlet pipe 5 can be connected to the reservoir in the residential area.

[0032] The main outlet pipe 6 has a connected outlet end and at least one inlet end. Each inlet end of the main outlet pipe 6 is connected to the outlet of a centrifugal pump 1.

[0033] Optionally, the outlet end of the main water pipe 6 can be connected to the water supply network in the residential building to supply water to the residents.

[0034] Furthermore, the outlet end of the main water outlet pipe 6 and the inlet end of the main water inlet pipe 5 can be located on the same side. For example, an opening can be made on one side wall of the cabinet 100, and the outlet end of the main water outlet pipe 6 and the inlet end of the main water inlet pipe 5 can be installed on the same side wall of the cabinet 100 through the opening.

[0035] It should be noted that the number of inlet ends of the main outlet pipe 6 is consistent with the number of centrifugal pumps 1.

[0036] The pressure tank 4 is located in the internal space and connected to the other side wall of the cabinet 100. The pressure tank 4 is connected to the main water outlet pipe 6.

[0037] Optionally, the pressure tank 4 can be a diaphragm-type pressure tank 4. The connection between the pressure tank 4 and the other side wall of the cabinet 100 can be a detachable and fixed connection between the pressure stabilizing tank 2 and the other side wall of the cabinet 100. The connection between the pressure tank 4 and the main water outlet pipe 6 can be such that the pressure tank 4 is located above the main water outlet pipe 6, and the water outlet of the pressure tank 4 is perpendicularly connected to the opening on the top wall of the main water outlet pipe 6.

[0038] It should be understood that the top wall of the cabinet 100 is also connected to the electrical control box 200. Optionally, the connection between the electrical control box 200 and the top wall of the cabinet 100 can be a detachable and fixed connection.

[0039] On the one hand, the electrical control box 200 is electrically connected to an external power source; on the other hand, the electrical control box 200 is electrically connected to the centrifugal pump 1 to control the centrifugal pump.

[0040] Working principle: Centrifugal pump 1 is started. Driven by centrifugal pump 1, water in the reservoir flows into pressure tank 2 through the outlet of the main inlet pipe 5. Water in pressure tank 2 flows into centrifugal pump 1 through the outlet of the first transfer pipe 3. Centrifugal pump 1 continues to transport water to the main outlet pipe 6 through the inlet of the main outlet pipe 6, and then to the water supply network through the outlet of the main outlet pipe 6, realizing secondary water supply. Pressure tank 2 can buffer the water flow in the main inlet pipe 5 and stabilize the water pressure, which can not only ensure a smooth water flow, but also avoid frequent start-stop of centrifugal pump 1 due to excessive water pressure changes. Because the centrifugal pump 1 does not have high precision in controlling water pressure, pressure tank 4 can maintain constant inlet and outlet pressure, ensuring that water in the reservoir can be stably and continuously transported to the water supply network. The integrated secondary water supply device of this utility model integrates the above-mentioned equipment components into the cabinet 100 in a modular design, which can be adapted to secondary water supply in various scenarios such as residences, construction sites, and emergency locations. It does not require the installation of a customized foundation, supports rapid hoisting and mobile deployment, and improves asset reuse rate. Through the cooperation of the pressure tank 4 and the pressure stabilizing tank 2, the stability and continuity of the secondary water supply are achieved.

[0041] In some implementations, each outlet of the first transfer pipe 3 and the inlet of each centrifugal pump 1 are connected by a first flange butterfly valve 7.

[0042] The use of the first flange butterfly valve 7 facilitates the installation and disassembly between the first transfer pipe 3 and the centrifugal pump 1. By closing the first flange butterfly valve 7, the passage between the first transfer pipe 3 and the centrifugal pump 1 can be cut off, preventing water from the main inlet pipe 5 from entering the centrifugal pump 1, which is beneficial for disassembling and maintaining the centrifugal pump 1.

[0043] In some implementations, the outlet of each centrifugal pump 1 is connected to a second transfer pipe 8 via a flange, and each second transfer pipe 8 is connected to each inlet of the main outlet pipe 6 via a second flange butterfly valve 9.

[0044] The flange connection facilitates the installation and disassembly between the second transfer pipe 8 and the centrifugal pump 1, while the second flange butterfly valve 9 facilitates the installation and disassembly between the second transfer pipe 8 and the main outlet pipe 6. By closing the second flange butterfly valve 9, the passage between the main outlet pipe 6 and the second transfer pipe 8 can be cut off, preventing water from the main outlet pipe 6 from entering the centrifugal pump 1, which is beneficial for disassembling and maintaining the centrifugal pump 1.

[0045] In some embodiments, the second transfer pipe 8 is provided with a check valve 10.

[0046] When centrifugal pump 1 suddenly stops or reverses, check valve 10 automatically closes, cutting off the passage in the second transfer pipe 8 and preventing water flowing into the water supply network from flowing back into the reservoir, thus affecting the stability and continuity of the secondary water supply. In some feasible implementations, the pressure tank 2 is provided with a UV lamp plate (not shown in the figure) distributed circumferentially along the tank body.

[0047] It is worth noting that the UV lamp panel is electrically connected to the electrical control box 200.

[0048] UV lamp panels use short-wave ultraviolet light to destroy the DNA / RNA structure of microorganisms in water, achieving highly efficient sterilization and deodorization without altering the water's composition. They are safe, environmentally friendly, leave no chemical residue, and have low energy consumption. In some embodiments, the inner walls of the inlet main pipe 5 and the outlet main pipe 6 are respectively provided with at least one set of sensors (not shown in the figure), including a water quality sensor and a pressure sensor.

[0049] Understandably, the water quality sensor and the pressure sensor are electrically connected to the electrical control box 200 respectively. The pressure sensor is used to collect the inlet pressure of the inlet main pipe 5 and the outlet pressure of the outlet main pipe 6, so as to transmit the inlet pressure and outlet pressure data to the electrical control box 200 in real time to realize the control of the centrifugal pump 1.

[0050] Meanwhile, since the inlet and outlet water pressure data are obtained, the pressure stabilizing tank 2 and the air pressure tank 4 can be adjusted adaptively based on the inlet and outlet water pressure data to ensure that the device can stably and continuously supply secondary water.

[0051] Water quality sensors are used to collect data such as pH and turbidity of water, making it easier for operators to understand the water quality status.

[0052] In some embodiments, the integrated secondary water supply device also includes a water turbine generator 11 located in the internal space and connected to the top wall of the cabinet 100.

[0053] The water inlet of the hydro-generator 11 is connected to one side wall of the main outlet pipe 6, and the water outlet of the hydro-generator 11 is connected to the other side wall of the main outlet pipe 6.

[0054] The hydro-generator 11 is electrically connected to the electrical control box 200, so that it can be used to provide auxiliary power to the sensor.

[0055] When the centrifugal pump 1 stops working, the water in the main outlet pipe 6 will flow from the inlet of the water turbine generator 11 to the outlet. The water turbine generator 11 converts the water pressure potential energy into electrical energy and provides auxiliary power to the sensor to reduce external energy consumption.

[0056] Furthermore, since the UV lamp panel is electrically connected to the electrical control box 200, the hydro-generator 11 can also provide auxiliary power to the UV lamp panel, further reducing external energy consumption.

[0057] In some embodiments, the integrated secondary water supply device also includes a hydraulic lifting seat 12.

[0058] The hydraulic lifting seat 12 is configured to support the cabinet 100 and drive the cabinet 100 to rise and fall. The base of the hydraulic lifting seat 12 is equipped with multiple casters 13.

[0059] The hydraulic lifting platform 12 enables the lifting and lowering of the cabinet 100, which is suitable for different scenario requirements. The casters 13 facilitate the movement of the integrated secondary water supply device, further supporting rapid hoisting and mobile deployment.

[0060] Although embodiments of the present invention have been shown and described above, it is understood that the above embodiments are exemplary and should not be construed as limiting the present invention. Those skilled in the art can make changes, modifications, substitutions and alterations to the above embodiments within the scope of the present invention without departing from the principles and spirit of the present invention, and all such changes should fall within the protection scope of the claims of the present invention.
