Description

Technical Field

[0001] This utility model relates to the field of water treatment equipment technology, and in particular to a pressure-stabilizing pump room. Background Technology

[0002] In cities, municipal water supplies are provided to residential areas and factories, which may be located in high-rise buildings. The water pressure provided by the municipal water supply is limited, and in some higher floors, the municipal water supply may not reach them sufficiently, resulting in low water pressure or no water at all. To ensure the water needs of high-rise residents, pump rooms are installed near these areas. These pump rooms can increase water pressure when needed to ensure that higher floors also have a sufficient water supply.

[0003] Chinese patent CN221973135U discloses an integrated smart pump station equipped with a water pump connected to the municipal water supply pipeline. When users in residential areas or factories have water needs, the pump can draw water to supply them. While this method can improve the water experience for users in high-rise buildings, users typically use water frequently in short periods, leading to frequent pump start-ups and shutdowns. Furthermore, changes in the volume or pressure of the municipal water supply will also affect the water pressure and volume supplied to users through the pump station, impacting their water experience.

[0028] Exemplary embodiments will now be described more fully with reference to the accompanying drawings. However, these exemplary embodiments can be implemented in many forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided to make the present invention more comprehensive and complete, and to fully convey the concept of the exemplary embodiments to those skilled in the art. The same reference numerals in the drawings denote the same or similar structures, and therefore repeated descriptions of them will be omitted.

[0029] The terms used to describe position and direction in this utility model are illustrated with the accompanying drawings, but changes can be made as needed, and all such changes are included within the scope of protection of this utility model.

[0030] like Figure 1 and Figure 2 As shown, this utility model provides a pressure-stabilizing pump room, including a shell 1, an inlet pipe 2, an outlet pipe 3, a pump assembly 4, and a pressure-stabilizing assembly 5, and may also include a support assembly 6.

[0031] The outer casing 1 has internal space for accommodating the inlet pipe 2, outlet pipe 3, pump assembly 4, pressure stabilizing assembly 5, and support assembly 6. The outer casing 1 also has a pre-installed inlet port 11 and outlet port 12. The inlet port 11 can connect to the municipal water supply line to receive municipal water. After being processed by the inlet pipe 2, outlet pipe 3, pump assembly 4, and pressure stabilizing assembly 5, the municipal water can be discharged from the outlet port 12. The outlet port 12 connects to the user's inlet pipe, allowing water treated by the pressure stabilizing pump station to be supplied to the user through the outlet pipe 3.

[0032] The inlet pipe 2 is used to connect to the inlet interface 11 to receive municipal water and guide it into the pressure stabilizing pump room. The outlet pipe 3 is used to connect to the outlet interface 12 so that the treated water in the pressure stabilizing pump room can be discharged from the outlet interface 12.

[0033] The water pump assembly 4 is installed between the inlet pipe 2 and the outlet pipe 3. The water pump assembly 4 can draw water from the inlet pipe 2 to the outlet pipe 3 so that the water can be discharged from the outlet pipe 3. By drawing water from the inlet pipe 2, the water volume and water pressure can be increased, thereby ensuring that the outlet pipe 3 can supply sufficient water volume and water pressure to the user.

[0034] The water pump assembly 4 may include multiple water pumps 41. The inlet of each water pump 41 is connected to the inlet pipe 2, and the outlet of each water pump 41 is connected to the outlet pipe 3. The multiple water pumps 41 can be connected in parallel, meaning that the inlets of the multiple water pumps 41 are connected to different points on the inlet pipe 2, and the outlets of the multiple water pumps 41 are connected to different points on the outlet pipe 3. Specifically, the inlet pipe 2 is provided with a first connecting part 21, which has multiple spaced interfaces along the water flow direction. These interfaces are used to connect to the inlets of the water pumps 41. The outlet pipe 3 is provided with a third connecting part 31, which also has multiple spaced interfaces along the water flow direction. These interfaces are connected to the outlets of the water pumps 41. The multiple water pumps 41 can operate individually or simultaneously to meet different application scenarios. For example, when the water demand at the user end is small, only one water pump 41 can be operated; when the water demand at the user end is large, multiple water pumps 41 can be operated simultaneously.

[0035] The pressure stabilizing assembly 5 includes a flow stabilizing tank 51 connected to the inlet pipe 2 and a pressure tank 52 connected to the outlet pipe 3. The inlet pipe 2 may be provided with a second connection 22, and the flow stabilizing tank 51 may be connected to the second connection 22 of the inlet pipe 2. The second connection 22 of the inlet pipe 2 may be located downstream of the first connection 21 along the water flow direction. When there is water flowing in the inlet pipe 2, a portion of the water in the inlet pipe 2 will flow to the flow stabilizing tank 51 for storage. At this time, the water pump 41 may not work, i.e., the user has no water demand. When the user has a water demand and the water supply from the municipal water supply is insufficient, the water in the flow stabilizing tank 51 can be supplied to the inlet pipe 2 to increase the water volume and pressure, thereby ensuring a stable water supply to the outlet pipe 3.

[0036] The flow stabilizing tank 51 may have two ports, each connected to the second connection part 22 of the inlet pipe 2 via a separate pipe. The flow stabilizing tank 51 receives water from the inlet pipe 2 through one port, and supplies water to the inlet pipe 2 through the other port. A valve may be installed between each port of the flow stabilizing tank 51 and the inlet pipe 2 to control the inflow or outflow of water.

[0037] The outlet pipe 3 may be equipped with a fourth connection 32, and the pressure tank 52 may be connected to the fourth connection 32 of the outlet pipe 3, with the fourth connection 32 located downstream of the third connection 31 along the water flow direction. The pressure tank 52 can selectively expand or compress to absorb or release water, thereby improving the stability of the water pressure. Specifically, a deformable elastic diaphragm is provided inside the pressure tank 52. When the water pressure in the outlet pipe 3 is too high, the elastic diaphragm of the pressure tank 52 is compressed, and the inside of the pressure tank 52 contracts and absorbs water, thereby reducing the outlet pressure; when the water pressure in the outlet pipe 3 is too low, the elastic diaphragm of the pressure tank 52 pops out, and the inside of the pressure tank 52 expands to release water, thereby increasing the outlet pressure. By adjusting the pressure tank 52, the stability of the outlet pressure can be ensured. In addition, when there is a small amount of water demand at the user end, the pressure tank 52 can expand and release water. The water released by the pressure tank 52 is supplied to the user. At this time, the water pump 41 does not need to be started, thereby reducing the number of times the water pump 41 is started and stopped and extending the service life of the water pump 41.

[0038] In some specific embodiments, along the first direction, the flow stabilizing tank 51, the water pump assembly 4, and the pressure tank 52 are arranged sequentially at intervals; along the second direction, the inlet pipe 2 and the outlet pipe 3 are arranged at intervals. The first direction and the second direction are perpendicular to each other; for example, the first direction is the length direction of the pressure-stabilizing pump room, and the second direction is the width direction of the pressure-stabilizing pump room. The flow stabilizing tank 51 is located on the side of the water pump assembly 4 away from the inlet port 11 and the outlet port 12, and the pressure tank 52 is located on the side of the water pump assembly 4 adjacent to the inlet port 11 and the outlet port 12.

[0039] By rationally distributing the flow stabilizer tank 51, water pump assembly 4, pressure tank 52, inlet pipe 2, and outlet pipe 3, the water treatment unit composed of the flow stabilizer tank 51, water pump assembly 4, pressure tank 52, inlet pipe 2, and outlet pipe 3 becomes more compact, reducing the volume of the water treatment unit. Consequently, the outer casing 1 cannot reserve a large space to accommodate the water treatment unit, thus reducing the volume of the pressure stabilizing pump room.

[0040] The bracket assembly 6 can be fixed to the bottom and / or side wall of the housing 1 using screws or other fasteners. The bracket assembly 6 is provided with multiple support parts to support and fix the inlet pipe 2, outlet pipe 3, pump assembly 4, and pressure stabilizing assembly 5, so that the inlet pipe 2, outlet pipe 3, pump assembly 4, and pressure stabilizing assembly 5 form an integrated water treatment unit. At the factory, the inlet pipe 2, outlet pipe 3, pump assembly 4, and pressure stabilizing assembly 5 can be pre-fixed to the bracket assembly 6, allowing the pressure stabilizing pump room to be pre-assembled as a whole. This integrated pressure stabilizing pump room can then be transported to the community or factory for installation, reducing the installation time at the community or factory.

[0041] In some specific embodiments, the outer casing 1 may include a first space 13 and a second space 14 that are interconnected. The first space 13 is used to install a water treatment unit consisting of an inlet pipe 2, an outlet pipe 3, a water pump assembly 4, and a pressure stabilizing assembly 5. The second space 14 may be used to install components such as a control module 141 and sensors. The outer casing 1 may also be provided with a door 15, which can be opened or closed to facilitate personnel access. The door 15 may be located on the side of the second space 14 away from the first space 13. The door 15 can be locked by a magnetic lock, which can be controlled by an opening button inside the door or a card reader outside the door.

[0042] A drainage ditch 17 can be excavated at the connection between the first space 13 and the second space 14. The drainage ditch 17 penetrates the outer shell 1, and an emergency lighting light is installed at the drainage ditch 17. The drainage ditch 17 facilitates the collection and discharge of water, thereby reducing the amount of water flowing from the first space 13 into the second space 14.

[0043] In some specific embodiments, a fan 16 is provided on the outer casing 1. The fan 16 rotates to facilitate the discharge of gas inside the outer casing 1, thereby improving the air quality inside the outer casing 1. There may be two fans 16, which are distributed at opposite ends of the outer casing 1, for example, at opposite ends of the first space 13 in the outer casing 1 along a first direction.

[0044] A control module 141 is installed within the second space 14. The control module 141 can control electronic components within the pressure-stabilizing pump room, such as the water pump 41 and various valves, to control the water flow. Specifically, along the second direction, the control module 141 is located on the side of the second space 14 away from the first space 13; along the first direction, the control module 141 is located on the side of the second space 14 away from the inlet port 11 and the outlet port 12. By keeping the control module 141 away from the water treatment unit, the degree to which the control unit is affected by water vapor or splashed water can be reduced. The control unit may include a power distribution cabinet and a frequency converter control cabinet, which can be sealed with doors and housings to further reduce the impact of water vapor on the internal electrical components.

[0045] In some specific embodiments, the pressure-stabilizing pump room may also be equipped with a dehumidifier 145 and an air conditioning unit 146. The dehumidifier 145 and the air conditioning unit 146 are located on one side adjacent to the water inlet 11 and the water outlet 12 along the first direction, and the dehumidifier 145 and the air conditioning unit 146 are connected to the control module 141 to receive control signals issued by the control module 141, thereby enabling the dehumidifier 145 and the air conditioning unit 146 to be controlled by the control module 141.

[0046] To facilitate the monitoring of the internal environment of the outer casing 1, multiple sensors can be installed in the second space 14 to detect various parameters. Specifically, the second space 14 can house a residual chlorine turbidity detector 142, a temperature and humidity detector 143, and a noise sensor 144. These sensors are all connected to the control module 141. Specifically, the residual chlorine turbidity detector 142 detects the residual chlorine content and air turbidity within the outer casing 1; the temperature and humidity detector 143 detects the temperature and humidity within the outer casing 1; and the noise sensor 144 detects the noise within the outer casing 1.

[0047] When the residual chlorine turbidity detector 142 detects a high residual chlorine content or high air turbidity inside the housing 1, the control module 141 receives the feedback from the residual chlorine turbidity detector 142 and can control the fan 16 to start to exhaust the gas inside the housing 1, allowing outside air to flow into the housing 1, thereby improving the air quality inside the housing 1. When the temperature and humidity detector 143 detects that the temperature and humidity inside the housing 1 are different from the required range, the control module 141 receives the feedback from the temperature and humidity detector 143 and can start the air conditioner and dehumidifier 145 to adjust the temperature and humidity inside the housing 1. When the noise sensor 144 detects a large noise inside the housing 1, the control module 141 receives the feedback from the noise sensor 144 and issues an alarm to remind personnel to check.

[0048] In addition, sensors can also be installed in the first space 13. For example, a smoke detector 131 connected to the control module 141 can be installed in the first space 13. The smoke detector 131 is used to detect smoke in the first space 13 so as to trigger an alarm when smoke is generated in the event of a fire or equipment damage.

[0049] 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.
