Description

Technical Field

[0001] This utility model relates to the field of drainage technology, specifically to a water supply and drainage system. Background Technology

[0002] Due to the thin air and insufficient oxygen content in high-altitude environments, pressurized chambers or pressurized structures have promising applications. However, pressurized chambers or pressurized structures require extremely high airtightness.

[0003] A water supply and drainage system is an essential component of a pressurized chamber. The drainage system must ensure the pressure and airtightness within the chamber. The drain pipes cannot be kept open indefinitely; valves are required to open them only when wastewater is being used. However, current research on drainage and water supply systems within pressurized chambers is limited. Existing systems, where indoor drain pipes are always connected to the outside, cannot guarantee airtightness when directly used in pressurized buildings. Therefore, ensuring both airtightness within the chamber and the normal operation of the water supply and drainage system is the focus of this invention. Summary of the Invention

[0004] The purpose of this utility model is to provide a water supply and drainage system that addresses the shortcomings of existing technologies. This system is designed to be integrated with a pressurization chamber to solve the problem of ensuring the airtightness of the pressurization chamber in existing technologies.

[0005] The technical solution adopted by this utility model is: a water supply and drainage system, including a first water-using device, a water supply pipeline, an internal wastewater pipeline, a wastewater tank, a pressurization mechanism, and a balancing pipeline;

[0006] The first water-using equipment is located in a sealed pressurized chamber, and the water supply pipeline is connected to the water inlet of the first water-using equipment;

[0007] The outlet of the first water-using device is connected to the inlet of the internal wastewater pipeline located at the bottom of the pressurization chamber; the internal wastewater pipeline is connected to the inlet of the wastewater tank.

[0008] The wastewater tank is located in the equipment room of the pressurization chamber, and the top of the wastewater tank is lower than the bottom of the pressurization chamber; the inner top of the wastewater tank is connected to the pressurization mechanism through a pressurization pipeline; the outlet of the wastewater tank is connected to the external wastewater pipeline.

[0009] One end of the balancing pipe is connected to the interior of the pressurization chamber, and the other end of the balancing pipe is connected to the interior of the wastewater tank. A balancing valve is installed on the balancing pipe.

[0010] According to the above scheme, the pressurizing mechanism is an air compressor unit. The outlet of the air compressor unit is connected to the pressurizing port located on the top of the wastewater tank through a pressurizing pipeline. The pressurizing port is equipped with a valve for opening or closing the pressurizing port.

[0011] According to the above scheme, the water supply and drainage system also includes a second water-using device, an internal sewage pipeline and a sewage tank. The second water-using device is installed in the pressurization chamber. The water inlet of the second water-using device is connected to the water supply pipeline, and the water outlet of the second water-using device is connected to the internal sewage pipeline. The internal sewage pipeline is connected to the inlet of the sewage tank located in the equipment room, and the outlet of the sewage tank is connected to the municipal drainage network through the external sewage pipeline.

[0012] According to the above plan, a pulverizing pump is installed on the external sewage discharge pipe.

[0013] According to the above plan, a sewage level detection device is installed inside the sewage tank to detect the sewage level inside the tank.

[0014] According to the above scheme, the wastewater tank is equipped with a wastewater level detection device for detecting the wastewater level in the wastewater tank.

[0019] The beneficial effects of this utility model are as follows:

[0020] 1. This utility model has a connecting balance pipe between the wastewater tank and the pressurization chamber. When it is necessary to discharge wastewater from the pressurization chamber to the wastewater tank, the balance pipe is opened, and the wastewater in the pressurization chamber flows into the wastewater tank under the action of gravity. When it is necessary to discharge the wastewater in the wastewater tank into the municipal drainage network, the balance pipe is closed, and the wastewater tank is pressurized by the pressurization mechanism to discharge the wastewater.

[0026] To better understand this utility model, it will be further described below with reference to the accompanying drawings and specific embodiments.

[0027] like Figure 1 The water supply and drainage system shown is specifically a sealed pressurized single-compartment water supply and drainage system, including a first water supply device, a water supply pipeline 22, an internal wastewater pipeline 9, a wastewater tank 11, a pressurization mechanism, and a balancing pipeline 13;

[0028] The first water-using equipment is located in a sealed pressurization chamber 20. One end of the water supply pipe 22 is connected to the municipal water supply network, and the other end of the water supply pipe 22 is inserted into the pressurization chamber 20 and connected to the water inlet of the first water-using equipment.

[0029] The outlet of the first water-using equipment is connected to the inlet of the internal wastewater pipeline 9 (buried in the floor 2 of the chamber) located at the bottom of the pressurization chamber 20;

[0030] The wastewater tank 11 is located inside the equipment room 25 of the pressurization chamber 20 (the equipment room 25 is adjacent to the pressurization chamber 20), and the top of the wastewater tank 11 is lower than the bottom of the pressurization chamber 20; the internal wastewater pipe 9 passes through the equipment room 25 and is connected to the inlet of the wastewater tank 11; the inner top of the wastewater tank 11 is connected to the pressurization mechanism through a pressurization pipe; the outlet of the wastewater tank 11 is connected to the municipal drainage network or the external drainage network through the external wastewater pipe 18.

[0031] One end of the balancing pipe 13 is connected to the interior of the pressurization chamber 20, and the other end of the balancing pipe 13 is connected to the interior of the wastewater tank 11. A balancing valve 15 is installed on the balancing pipe 13.

[0032] In this invention, the balancing pipe 13 connects the pressurization chamber 20 and the wastewater tank 11, and there is a height difference between the wastewater tank 11 and the pressurization chamber 20. After the balancing valve 15 on the balancing pipe 13 is opened, the wastewater from the first water-using equipment in the pressurization chamber 20 flows by gravity through the inner wastewater pipe 9 (which is equipped with a wastewater one-way valve 10) to the wastewater tank 11. When it is necessary to discharge the wastewater in the wastewater tank 11, the balancing valve 15 on the balancing pipe 13 is closed, and the wastewater tank 11 is pressurized through the pressurization mechanism and pressurization pipe, so that the wastewater in the wastewater tank 11 is discharged to the municipal drainage network or the external drainage network through the external wastewater pipe 18 (which is equipped with a wastewater pneumatic valve 27).

[0033] In this utility model, the first water-using equipment is a shower, a sink, or a faucet, etc. The floor drain below the shower and faucet and the water outlet at the bottom of the sink are all connected to the inlet of the internal wastewater pipe 9.

[0034] Preferably, the wastewater tank 11 is equipped with a wastewater level detection device 12 for detecting the wastewater level in the wastewater tank 11.

[0035] In this invention, when the wastewater level detection device 12 detects that the wastewater level in the wastewater tank 11 has reached the set drainage level, it closes the balance valve 15 on the balance pipe 13, starts the pressurization mechanism and opens the wastewater pneumatic valve 27 on the external wastewater pipe 18, pressurizes the wastewater tank 11 through the pressurization pipe, and discharges the wastewater in the wastewater tank 11; when the wastewater level detection device 12 detects that the wastewater level in the wastewater tank 11 has dropped to the set inlet level, it opens the balance valve 15 on the balance pipe 13, so that the inside of the pressurization chamber 20 and the inside of the wastewater tank 11 are connected, and the wastewater of the first water-using equipment in the pressurization chamber 20 enters the wastewater tank 11 for storage through the internal wastewater pipe 9.

[0036] Preferably, the pressurizing mechanism is an air compressor unit 17. The outlet of the air compressor unit 17 is connected to a pressurizing port 14 located on the top of the wastewater tank 11 via a pressurizing pipeline. The pressurizing port 14 is equipped with a valve for opening or closing the pressurizing port 14. The air compressor unit 17 injects air into the wastewater tank 11 through the pressurizing pipeline, pressurizing the wastewater tank 11 to discharge the wastewater inside.

[0037] In this utility model, the toilet 1 inside the pressurization chamber 20 can be equipped with a separate drainage system; specifically, the water supply and drainage system also includes a second water-using device, an internal sewage pipe 3, and a sewage tank 5; the second water-using device can be a toilet, installed inside the pressurization chamber 20, the water inlet of the second water-using device (specifically the toilet water tank 23) is connected to the water supply pipe 22, the water outlet of the second water-using device is connected to the internal sewage pipe 3, the internal sewage pipe 3 is connected to the inlet of the sewage tank 5 located in the equipment room 25, and the outlet of the sewage tank 5 is connected to the municipal drainage network through the external sewage pipe 7.

[0038] In this utility model, the sewage tank 5 is located at the lower part of the wastewater tank 11, and the sewage tank 5 is lower than the outlet end of the second water-using equipment; the internal sewage pipe 3 is equipped with a sewage pneumatic valve 4 (specifically located at the inlet of the sewage tank 5), and the external sewage discharge pipe is equipped with a pulverizing pump 6, which is used to pulverize the dirt in the sewage before discharging it.

[0039] Preferably, a sewage level detection device 8 is installed inside the sewage tank 5 to detect the sewage level inside the sewage tank 5.

[0040] In this invention, the sewage pneumatic valve 4 is opened, and sewage enters the sewage tank 5, where it is temporarily stored. When the sewage level detection device 8 detects that the sewage level in the sewage tank 5 has risen to the set discharge level, the sewage pneumatic valve 4 is closed, and the pulverizing pump 6 is started to pump the sewage out of the sewage tank 5 and discharge it to the outdoor municipal drainage network. When the sewage level detection device 8 detects that the sewage level in the sewage tank 5 has dropped to the inlet level, the pulverizing pump 6 is turned off, and the discharge of sewage into the municipal drainage network is stopped.

[0041] In this invention, the toilet 1 can be a wall-hung toilet, a smart toilet, or a floor-standing toilet. If a wall-hung toilet 1 is used, the toilet tank 23 is concealed within the outer steel structure 21 of the pressurization chamber 20. The drain outlet of the toilet 1 is connected to the sewage pneumatic valve 4 via an internal sewage pipe 3 and an outlet steel sleeve. In this embodiment, the other configurations, usage methods, and working principles of the toilet 1 inside the pressurization chamber 20 are consistent with those of a conventional household toilet 1, and will not be described further here.

[0042] Preferably, a water supply pump 26 is installed on the water supply pipeline 22 within the equipment room 25. When the water-using equipment in the pressurization chamber 20 needs water, water from the municipal water supply network is delivered to each water-using equipment in the pressurization chamber 20 through the water supply pump 26 and the water supply pipeline 22. Specifically, the water supply pump 26 is a water supply diaphragm pump.

[0043] In this utility model, the sewage pneumatic valve 4 is supplied with air through the air compressor unit 17 (specifically, the air source channel of the sewage pneumatic valve 4 is connected to the air compressor unit 17 through the air pipe 16, which is the prior art). When the pressure in the air pipe of the sewage pneumatic valve 4 is lower than the set value, the air compressor unit 17 is started to replenish the pressure in the air pipe of the sewage pneumatic valve 4.

[0044] In this utility model, the wastewater pneumatic valve 27, the balancing valve 15, and the valve controlling the opening and closing of the pressurization port 14 are all pneumatic valves, and the air source is supplemented by the air compressor unit 17; the pressurization port 14 of the wastewater tank 11 is also supplemented by the air compressor.

[0045] In this invention, each electrical-required device, such as the pulverizing pump 6 and the air compressor unit 17, is connected to the power source via a power cord and is powered by the power source; this is known technology and will not be described in detail here.

[0046] The working principle of this utility model is as follows:

[0047] Water from the municipal water supply network is delivered to corresponding water-using equipment such as showers, sinks, or toilet tanks 23 via a diaphragm pump and water supply pipeline 22. For wastewater discharge from sinks and showers, during drainage, the balancing valve 15 on the balancing pipe 13 is opened. Wastewater from sinks and showers flows under gravity through the internal wastewater pipeline 9 and the wastewater check valve 10 from the pressurization chamber 20 to the wastewater tank 11 in the equipment room 25 for storage. When the wastewater level in the wastewater tank 11 rises to the discharge level, the balancing valve 15 in the balancing pipe 13 is closed. Wastewater from the showers and sinks inside the pressurization chamber 20 can no longer be discharged into the wastewater tank 11 by gravity through the wastewater check valve. Simultaneously, to discharge wastewater from the wastewater tank 11, the wastewater pneumatic valve 27 on the external wastewater pipeline 18 is opened, and the air compressor unit 17 is started, discharging wastewater through the top of the wastewater tank 11. The pressurization port 14 of the unit supplies gas (which can be air) to pressurize the wastewater tank 11. The original space of the wastewater inside the wastewater tank 11 is quickly occupied by the air rapidly introduced by the air compressor unit 17, and then it is quickly discharged from the external wastewater pipeline 18 to the municipal drainage network or the external drainage network (the entire drainage process is completed in about 10 seconds). After the wastewater in the wastewater tank 11 is emptied, the air inside the wastewater tank 11 enters the municipal drainage network, and the pressure inside the wastewater tank 11 is basically the same as that inside the municipal drainage network. At this time, the wastewater pneumatic valve 27 on the air compressor unit 17 and the external wastewater pipeline 18 is closed, and the balance valve 15 on the balance pipeline 13 is opened. The wastewater from the shower and the sink continues to be stored in the wastewater tank 11. Wastewater from toilet 1 is discharged into wastewater tank 5 through internal wastewater pipe 3. When the wastewater level in wastewater tank 5 rises to the discharge level, the pulverizing pump 6 on external wastewater pipe 7 is turned on to extract the wastewater from wastewater tank 5, pulverize the waste, and discharge it into the municipal drainage network.

[0048] like Figure 2As shown, this utility model can also incorporate a controller 19. The air compressor unit 17 and the pulverizing pump 6 can be connected to the controller 19 via signal lines, and the controller 19 controls their opening or closing. The balancing valve 15 on the balancing pipeline 13 is a balancing pneumatic valve. The balancing pneumatic valve and the sewage pneumatic valve 4 can both be connected to the controller 19 via corresponding solenoid valves (the corresponding solenoid valves are connected to the controller 19 via signal lines 19). The controller 19 controls the opening or closing of the corresponding balancing pneumatic valve or sewage pneumatic valve 4 via the solenoid valves. The liquid level detection devices of the wastewater tank 11, the sewage tank 5, and the toilet tank 23 can all be liquid level sensors. Each liquid level sensor is connected to the controller 19 via a signal line, sending the detected liquid level information to the controller 19. The controller 19 controls the opening or closing of the valves and equipment according to the corresponding liquid level signals.

[0049] If the wastewater level detection device 12 detects that the liquid level in the wastewater tank 11 has risen to the set discharge level, it sends a level signal to the controller 19. The controller 19 controls the balance valve 15 to close, the wastewater check valve 10 to close, and the air compressor unit 17 to start. The air compressor unit 17 pressurizes the wastewater tank 11 through the pressurization port 14. The wastewater in the wastewater tank 11 is squeezed out of the wastewater tank 11 by the pressurized air and discharged into the external municipal pipe network or external drainage facilities. If the wastewater level detection device 12 detects that the liquid level in the wastewater tank 11 has dropped to the set storage level (the wastewater tank 11 can be directly set to be emptied), it sends a level signal to the controller 19. The controller 19 controls the balance valve 15 to open, the wastewater check valve 10 and the air compressor unit 17 to close. The wastewater from the first water-using equipment, such as the handwashing sink, flows into the wastewater tank 11 for storage under the action of gravity through the internal wastewater pipe 9.

[0050] For example, after toilet 1 is used, the water level in toilet tank 23 drops. When toilet tank level detection device 24 detects that the water level in toilet tank 23 has dropped to the set level, it transmits the water level signal of toilet tank 23 to controller 19. Controller 19 controls the sewage pneumatic valve 4 to open through the corresponding solenoid valve, and sewage enters sewage tank 5 through sewage pneumatic valve 4. When sewage level detection device 8 detects that the sewage level in sewage tank 5 has risen to the set sewage discharge level, it sends the level signal to controller 19. Controller 19 controls the pulverizing pump 6 to start, pumping out the sewage in sewage tank 5, pulverizing the waste, and discharging it. When sewage level detection device 8 detects that the sewage level in sewage tank 5 has dropped to the set storage water level, controller 19 controls the pulverizing pump 6 to shut down, stopping the discharge of sewage.
