Abstract
Description
Technical Field
[0001] This utility model relates to the field of building water pressure boosting technology, specifically to a booster pump for single-pipe water supply and drainage in rooftop water storage towers. Background Technology
[0002] In rural areas and areas with self-built houses, a combination of rooftop water towers and well water is commonly used for daily water supply. Traditional water supply systems typically use a single-pipeline system, where a self-priming pump pumps well water through the same pipe to the rooftop water tower, and then gravity flows to supply water to lower-floor residents. This model has a significant drawback: when users want to install a booster pump at the water tower outlet to improve water pressure on lower floors, pipe conflicts arise. The booster pump, when operating, obstructs the water flow, preventing the self-priming pump from properly pumping water into the water tower.
[0003] To address this issue, existing solutions primarily involve adding a separate water supply pipe to the building's exterior wall, creating two independent piping systems for "water supply" and "pressurization." Alternatively, they can achieve functional switching by adding a bypass pipe and solenoid valve to the existing single pipe and laying complex control wiring. However, both solutions have significant drawbacks: adding a separate pipe involves substantial construction work, resulting in cluttered exterior wall wiring that affects aesthetics, and exposed pipes are prone to aging due to long-term exposure to sun and rain, leading to high maintenance costs. On the other hand, adding a bypass solenoid valve requires laying long electrical wires, which is equally cumbersome to install and carries risks such as wiring aging and a high failure rate.
[0004] Therefore, there is an urgent need for a solution that does not require modification of the existing single-pipe system, does not require additional control wiring, is easy to install, and operates stably. Utility Model Content
[0005] I. Technical problems to be solved
[0006] The technical problem this utility model aims to solve is that adding a separate water supply pipe or a bypass solenoid valve to the exterior wall is troublesome to install, the exterior wall pipelines are unsightly and prone to aging, and the maintenance cost is high.
[0007] II. Technical Solution
[0008] To solve the above-mentioned technical problems, the technical solution provided by this utility model is: a booster pump for single-pipe water supply and drainage of rooftop water storage towers, including a water tower, a self-priming pump, a booster pump unit, and a collaborative wireless controller;
[0009] The self-priming pump is installed at the water well and is used to pump the well water to the water tower;
[0010] The booster pump unit includes a booster pump body, an electric motor, a pressure tank, and an electric three-way valve;
[0011] The electric three-way valve includes a three-way valve body and an electric actuator. The three-way valve body has three ports, which are respectively connected to the water inlet from the self-priming pump, the water supply channel to the water tower, and the pressurization channel to the user's pipeline.
[0012] The collaborative wireless controller includes a signal transmitter and a receiver controller. The signal transmitter is electrically connected to the self-priming pump and is used to send a wireless signal when the self-priming pump starts or stops. The receiver controller is electrically connected to the electric actuator and is used to receive the wireless signal and control the switching channel of the electric three-way valve.
[0013] When the self-priming pump starts, the collaborative wireless controller controls the electric three-way valve to close the booster channel and open the water supply channel; when the self-priming pump stops, it controls the electric three-way valve to close the water supply channel and open the booster channel.
[0014] As an improvement, the booster pump unit also includes a water flow pressure switch and a booster pump controller. The water flow pressure switch detects the water pressure in the pipeline and transmits a signal to the booster pump controller to control the start and stop of the booster pump. The motor end is provided with motor fan blades.
[0015] As an improvement, the booster pump unit also includes an equipment housing and a housing base, wherein the booster pump body, motor, pressure tank and electric three-way valve are all installed inside the housing or on the base.

[0021] As an improvement, the system is applicable to water supply in multi-story buildings, including water supply points on different floors, such as the 1st, 2nd, and 3rd floors.
[0022] III. Beneficial Effects
[0023] The advantages of this utility model compared with the prior art are as follows:
[0024] This invention achieves automatic mode switching on a single pipeline through the cooperation of a wireless collaborative controller and an electric three-way valve. It eliminates the need to add a separate water supply pipe to the exterior wall and to lay complex physical control lines from the well to the roof, greatly simplifying the installation process and reducing material and construction costs.
[0025] The booster pump unit adopts a highly integrated modular design, integrating the pump body, motor, pressure tank, three-way valve, and controller into one compact unit, facilitating on-site installation. The motor is equipped with a dedicated fan blade, ensuring excellent heat dissipation and operational stability under prolonged high-load operation, resulting in a longer service life.
[0026] The system automatically triggers a wireless signal by detecting the start and stop status of the self-priming pump, controlling the water circuit switching and the operation of the booster pump. This enables unattended automatic switching between the "water supply" and "boosting" modes, providing a good user experience and solving the core pain point of traditional single-pipe systems where it is difficult to install booster pumps.
[0027] The signal transmitter is innovatively integrated into the multi-functional socket housing, which not only protects the internal components but also provides an extended power interface for easy on-site power supply and use of other devices, improving the product's practicality and integration and filling a market gap.

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.
[0033] As attached Figure 1 As shown, this utility model provides a booster pump for single-pipe water supply and drainage in rooftop water towers to solve its technical problems. Through wireless collaborative control and the cooperation of an electric three-way valve, the system achieves automatic water supply and automatic pressure boosting on a single pipeline, effectively solving the problems of low water pressure and difficulty in installing booster pumps in traditional rural single-pipe water tower pipelines.
[0034] The system mainly includes a water tower, a self-priming pump, a booster pump unit, and a collaborative wireless controller.
[0035] The self-priming pump is located at the well, and its core function is to pump well water to the rooftop water tower for storage, providing a water source for the entire system.
[0036] The booster pump unit is the core actuator of this system. (See attached...) Figure 2 As shown, the unit includes a housing 1 and its base 16, a booster pump body 10, a motor 14, a pressure tank 9, an electric three-way valve 15, a water flow pressure switch 12, and a booster pump controller 6. The booster pump body 10, motor 14, pressure tank 9, and electric three-way valve 15 are all integrated and installed inside the housing 1 or on the base 16, forming a compact and easy-to-install integrated module. The motor 14 has a fan blade 11 at its end, which enhances forced air cooling of the motor, ensuring that the booster pump maintains a low temperature rise even during long-term or high-load operation, thereby guaranteeing the stability and service life of the equipment. The booster pump unit is equipped with a power plug 13 for powering the entire unit.
[0037] The electric three-way valve 15 is a key component for realizing the single-pipe dual-channel function, consisting of a three-way valve body 7 and an electric actuator 2. The three-way valve body 7 has three ports, which are respectively connected to the water inlet from the self-priming pump, the water supply channel to the water tower, and the booster channel to the user's pipeline. The electric three-way valve 15 is connected to the booster pump body 10 via a bypass stainless steel flexible hose 8. This hose can not only accommodate misalignment during installation but also absorb vibrations and noise generated by the pump operation to a certain extent. The booster pump body 10 itself has a booster inlet / outlet 17 and a booster outlet / inlet 4, which function to connect to the single-pipe water supply pipeline, allowing the system to be connected in series to the existing pipeline.
[0038] The aforementioned collaborative wireless controller enables wireless linkage between the self-priming pump and the booster pump unit, eliminating the need for complex control wiring and thus saving the installation process from the intricate physical wiring between the well and the roof. (See attached image) Figure 3 As shown, the controller includes a signal transmitter 20 and a receiver controller 5. The signal transmitter 20 is electrically connected to the self-priming pump next to the well. Its function is to monitor the working status of the self-priming pump in real time and send corresponding wireless control signals accordingly. The signal transmitter 20 is integrated into an independent socket housing 21. The housing has an outer cover 18 installed on the upper side, and the housing has an expansion socket hole 22 and a self-use power plug 23, which also functions as a power strip, facilitating on-site power supply and powering other equipment, thus improving the practicality and integration of the product. The signal transmitter 20 is equipped with a transmitter antenna 19, which enhances the transmission strength and reliability of the wireless signal. The receiver controller 5 is installed near the booster pump unit and is electrically connected to the electric actuator 2. Its function is to receive and decode the wireless signal from the transmitter, and then precisely control the electric three-way valve 15 to switch channels according to preset logic. It is equipped with a receiver antenna 3 to ensure the sensitivity and stability of signal reception.
[0039] The working principle of this utility model is as follows:
[0040] Water supply process: When the water level in the rooftop water tower is insufficient and water needs to be added, the self-priming pump located at the well starts. Simultaneously with the self-priming pump's operation, the signal transmitter 20 in the electrically connected wireless controller detects the current signal in real time and immediately transmits a wireless command encoded as "water supply mode". The receiver controller 5, installed near the booster pump unit, captures this signal through its receiving antenna 3. After decoding by its internal circuitry, it sends an action command to the electric actuator 2 of the electric three-way valve 15. The electric actuator 2 drives the valve core inside the three-way valve body 7 to rotate, precisely switching the water circuit state: closing the booster channel to the user's pipe network while fully opening the water supply channel to the rooftop water tower. At this time, well water is drawn by the self-priming pump, flows through the opened water supply channel, and smoothly enters the rooftop water tower. During this process, the water flow pressure switch 12 inside the booster pump unit detects a continuous and stable water flow towards the water tower in the pipeline and transmits a signal to the booster pump controller 6. Based on this logic, the booster pump controller 6 determines that the system is in the water supply state and controls the booster pump body 10 and the motor 14 to enter the pressure holding standby state or completely stop working, thereby avoiding power conflict with the self-priming pump or doing useless work, realizing energy saving and efficient and automated operation of the entire water supply process.
[0041] Pressurization Process: When the water level in the water tower reaches the set height, the self-priming pump stops working. Signal transmitter 20 detects the disappearance of current and immediately transmits a wireless command coded as "pressurization mode". Upon receiving this signal, receiver controller 5 quickly controls electric actuator 2 to reverse its action, driving electric three-way valve 15 to switch positions: closing the water supply channel to the water tower while simultaneously fully opening the pressurization channel to the user's pipe network. At this point, the system's water circuit is fully connected to the user's water usage points. When a user turns on any faucet or shower in their home, the water pressure in the pipe network drops instantly. At this time, water flow pressure switch 12 sensitively detects this pressure change or slight water flow, immediately triggering and sending a start signal to booster pump controller 6. Booster pump controller 6 then starts motor 14 and booster pump body 10, drawing water from the rooftop water tower and providing a strong and stable pressurized water flow to the entire user's pipe network. This significantly improves the water pressure at lower floors (first, second, and third floors) or at water usage points farther from the water tower, effectively enhancing the user's water usage experience. When the user turns off the water supply point, the pipeline pressure rises to the set threshold, the water flow pressure switch 12 is turned off, the booster pump controller 6 controls the booster pump to stop working, and the system returns to standby mode, waiting for the next water use or water supply command.
