Description

Technical Field

[0001] This utility model belongs to the field of swimming pool water treatment technology, specifically a swimming pool chemical dosing device. Background Technology

[0002] In swimming pool water quality management, chemical dosing is a crucial step in ensuring water safety. A search revealed a unidirectional chemical dosing pipe for water quality adjustment in water delivery pipelines, authorized by patent number CN114811125B. This device, through a combination of a threaded sleeve, a one-way valve core, and a connecting pipe, achieves targeted chemical dosing in the water delivery pipeline, featuring convenient assembly and disassembly, simple maintenance, and high flexibility. However, this device primarily relies on the natural diffusion of chemicals driven by water flow, lacking a precise control mechanism for the dosage. It is difficult to dynamically adjust the dosing rate based on real-time changes in water quality, potentially leading to overdosing or underdosing, affecting water quality stability and safety. Furthermore, this device lacks intelligent monitoring and feedback control functions, still requiring periodic manual inspection and intervention, failing to meet the demands of modern swimming pool management for intelligence and automation. In addition, its relatively simple structural design limits its adaptability to different flow conditions or the combined dosing of multiple chemicals.

[0003] Therefore, there is an urgent need to design a swimming pool dosing device to solve the problems of insufficient dosing accuracy and low level of intelligence mentioned above. Utility Model Content

[0004] The swimming pool dosing devices mentioned in the article lack precise control mechanisms, have low levels of intelligence, and limited adaptability. Therefore, a swimming pool dosing device is proposed to achieve dynamic adjustment of the dosage, synergistic addition of multiple agents, and intelligent monitoring and feedback control.

[0005] To achieve the above objectives, the specific technical solution of the swimming pool dosing device of this utility model is as follows:

[0006] A swimming pool chemical dosing device includes a chemical storage unit, a metering unit, a mixing unit, and a control unit. The chemical storage unit is connected to the metering unit via a pipeline, the metering unit is connected to the mixing unit via a pipeline, and the mixing unit is connected to the pool water supply pipeline via a pipeline. The control unit is electrically connected to the chemical storage unit, the metering unit, and the mixing unit. The chemical storage unit stores different types of chemicals, the metering unit dynamically adjusts the output of chemicals according to water quality parameters, the mixing unit uniformly mixes multiple chemicals and injects them into the water supply pipeline, and the control unit monitors water quality parameters in real time and generates dosing commands.

[0007] Furthermore, the drug storage unit includes multiple independently installed drug storage tanks. Each tank is equipped with a liquid level sensor, which is connected to the control unit. The bottom of each tank is connected to the metering unit via a discharge pipe. A solenoid valve is installed on the discharge pipe, which is also connected to the control unit and is used to open or close the discharge pipe according to control commands.

[0008] Furthermore, the metering unit includes multiple metering pumps. The inlet of each metering pump is connected to the corresponding drug storage tank discharge pipe via a pipeline, and the outlet is connected to the mixing unit via a pipeline. The operating frequency of the metering pumps is adjusted by a control unit to dynamically adjust the output rate of the reagent according to water quality parameters.

[0009] Furthermore, the mixing unit includes a mixing chamber and a stirring assembly. The mixing chamber has a drug inlet at the top, which is connected to the outlet of a metering pump via a pipeline. The mixing chamber also has a drug outlet at the bottom, which is connected to the pool water supply pipeline via a valve. The stirring assembly includes a motor and a stirring shaft. The motor is mounted on the side of the mixing chamber. One end of the stirring shaft is connected to the motor output shaft, and the other end extends into the mixing chamber. The stirring shaft has multiple stirring blades for uniformly mixing the drugs entering the mixing chamber.

[0010] Furthermore, the control unit includes a water quality monitoring module, a data processing module, and an execution module. The water quality monitoring module includes multiple sensor probes installed on the inner wall of the pool water supply pipe for real-time collection of water quality parameters. The data processing module receives the data transmitted by the water quality monitoring module and generates dosing instructions based on a preset algorithm. The execution module receives the dosing instructions and sends control signals to the solenoid valve of the chemical storage unit and the metering pump of the metering unit, respectively.

[0011] Furthermore, the medicine storage tank has a cylindrical structure, with a sealing cap on the top. The sealing cap is connected to the open end of the medicine storage tank by threads, and the bottom of the medicine storage tank has a conical structure. The lowest point of the conical structure is connected to the discharge pipe to ensure that the medicine is completely discharged.

[0012] Furthermore, the metering pump is a diaphragm metering pump. The pump body of the diaphragm metering pump is bolted to the support plate. Both the inlet and outlet ends of the pump body are equipped with quick-connect interfaces, which are connected to the pipeline by clamps for quick disassembly and maintenance.

[0013] Furthermore, the stirring blades have a spiral structure and are evenly distributed along the stirring shaft axis. A gap is left between the outer edge of the stirring blades and the inner wall of the mixing chamber to avoid excessive frictional resistance during the stirring process.

[0014] Furthermore, the sensor probes of the water quality monitoring module include a pH sensor, a residual chlorine sensor, and a turbidity sensor. The sensor probes are installed on the inner wall of the pool water supply pipe via threads, and the signal lines of the sensor probes are connected to the data processing module through a waterproof connector for real-time transmission of water quality parameters.

[0015] The swimming pool dosing device of this invention has the following advantages:

[0016] The chemical storage unit utilizes multiple independently designed tanks to store various chemicals in a categorized manner. The conical structure at the bottom of each tank ensures complete discharge of chemicals, minimizing waste.

[0026] This utility model's swimming pool dosing device achieves precise management and automated control of swimming pool water quality through the coordinated operation of a storage unit, a metering unit, a mixing unit, and a control unit. The following is in conjunction with... Figures 1 to 4 The accompanying drawings and reference numerals provide a detailed description of the specific embodiments of this utility model. Example

[0027] In this embodiment, as Figure 1 As shown, the overall structure of this utility model includes a drug storage unit, a metering unit, a mixing unit, and a control unit (not shown in the figure). The units are connected by pipelines to form a complete drug delivery system.

[0028] The drug storage unit consists of multiple independently installed drug storage tanks 1, each of which is equipped with a liquid level sensor 2. Figure 2 As shown, the liquid level sensor 2 is connected to the data processing module in the control unit via a signal line, and is used to monitor the amount of medicine in the medicine storage tank 1 in real time.

[0029] In addition, the bottom of the medicine storage tank 1 is conical, and the lowest point of the conical structure is connected to the medicine discharge pipe 3. A solenoid valve 4 is installed on the medicine discharge pipe 3. The solenoid valve 4 is connected to the execution module in the control unit through a signal line. When the control unit issues an opening command, the solenoid valve 4 opens, and the medicine in the medicine storage tank 1 flows into the metering unit through the medicine discharge pipe 3.

[0030] In addition, a support frame 14 is provided below the medicine storage tank 1. The middle of the support frame 14 is the same as the conical structure below the medicine storage tank 1, which is used to limit the conical structure. Multiple columns are provided below the support frame 14, and the columns are connected to the support frame 14 and the base plate 16 by bolts. Example

[0031] A metering unit is provided based on Example 1.

[0032] In this embodiment, the metering unit includes multiple metering pumps 5, such as... Figure 3 As shown, the inlet end of each metering pump 5 is connected to the discharge pipe 3 of the corresponding drug storage tank 1 through a pipeline, and the outlet end is connected to the mixing unit through a pipeline.

[0033] Among them, the metering pump 5 is a diaphragm metering pump. Its pump body is bolted to the support plate, and the support plate is connected to the upper surface of the base plate 16 through the support column. The inlet and outlet ends of the pump body are equipped with quick-connect interfaces, which are connected to the pipeline through clamps, making it easy to quickly disassemble and maintain.

[0034] In addition, the operating frequency of the metering pump 5 is adjusted by the control unit. The control unit generates a dosing command based on the water quality parameters collected by the water quality monitoring module and sends the command to the execution module. The execution module adjusts the operating frequency of the metering pump 5 according to the command, thereby dynamically controlling the output rate of the chemical. Example

[0035] A mixing unit is provided based on Example 1.

[0036] In this embodiment, as Figure 4 As shown, the mixing unit includes a mixing chamber 6 and a stirring assembly 7. The top of the mixing chamber 6 is provided with a drug inlet 11. The drug inlet 11 at the top of the mixing chamber 6 is connected to the outlet end of the metering pump 5 through a pipeline. After the drug flows out of the metering pump 5, it enters the mixing chamber 6 through the drug inlet 11.

[0037] The mixing chamber 6 has an anti-corrosion coating on its inner wall to extend its service life. The bottom of the mixing chamber 6 has a medicine outlet 12, which is connected to the pool water supply pipe through a valve 13. The mixed medicine is injected into the water supply pipe through the medicine outlet 12.

[0038] In addition, the stirring assembly 7 includes a motor 8, a stirring shaft 9, and stirring blades 10. The motor 8 is installed on the side of the mixing chamber 6. One end of the stirring shaft 9 is connected to the output shaft of the motor 8, and the other end extends into the interior of the mixing chamber 6. Multiple spiral stirring blades 10 are provided on the stirring shaft 9. The stirring blades 10 are evenly distributed along the axial direction of the stirring shaft 9. A gap is left between the outer edge of the stirring blades 10 and the inner wall of the mixing chamber 6 to avoid excessive frictional resistance during the stirring process.

[0039] The motor 8 is connected to the execution module in the control unit via a signal line. When the medicine enters the mixing chamber 6, the execution module starts the motor 8, and the stirring component 7 starts to work, mixing the various medicines evenly.

[0040] The control unit includes a water quality monitoring module (not shown in the figure), a data processing module (not shown in the figure), and an execution module (not shown in the figure). The water quality monitoring module includes multiple sensor probes (not shown in the figure). The sensor probes are threaded onto the inner wall of the pool water supply pipe, and the signal lines of the sensor probes are connected to the data processing module through waterproof connectors.

[0041] The sensor probes include a pH sensor, a residual chlorine sensor, and a turbidity sensor, which are used to collect pool water quality parameters in real time and transmit the data to the data processing module.

[0042] The data processing module receives data transmitted from the water quality monitoring module and generates dosing instructions based on a preset algorithm.

[0043] After receiving the dosing command, the execution module sends control signals to the solenoid valve 4 of the drug storage unit and the metering pump 5 of the metering unit, respectively, to achieve precise control over the drug discharge of the drug storage tank 1 and the operation of the metering pump 5.

[0044] In practical applications, pool management personnel first store different types of chemicals in separate storage tanks 1, sealing the tanks with sealing caps 15 to ensure safe storage. A level sensor 2 monitors the chemical level in storage tank 1 in real time and transmits the data to the data processing module in the control unit. When chemical dosing is required, the sensor probe of the water quality monitoring module collects water quality parameters from the pool's water supply pipes, such as pH value, residual chlorine concentration, and turbidity, and transmits the data to the data processing module. The data processing module analyzes the water quality parameters according to a preset algorithm and generates corresponding dosing instructions. For example, when the pH value of the pool water is detected to be too high, the data processing module generates an instruction to increase the dosage of acidic chemicals; when the residual chlorine concentration is too low, it generates an instruction to increase the dosage of chlorine-containing chemicals. After receiving the dosing instructions, the execution module sends control signals to the solenoid valve 4 of the storage unit and the metering pump 5 of the metering unit. The solenoid valve 4 opens or closes according to the instructions, controlling the flow of chemicals from storage tank 1 into metering pump 5; the metering pump 5 adjusts its operating frequency according to the instructions, controlling the output rate of the chemicals. After the chemicals enter the mixing chamber 6 through the pipeline, the motor 8 starts, and the stirring component 7 begins to work, uniformly mixing the various chemicals. The mixed chemicals are then injected into the pool water supply pipe through the outlet 12, and finally enter the pool.

[0045] In the daily management of swimming pools, the swimming pool chemical dosing device of this invention can dynamically adjust the dosage of chemicals according to changes in water quality, achieving coordinated dosing of multiple chemicals. For example, during peak swimming pool hours, due to the increased possibility of external pollution, the water quality monitoring module frequently collects water quality parameters, and the control unit adjusts the chemical dosing strategy based on real-time data to ensure that the water quality remains within a safe range. During off-peak hours, the device can reduce the dosage of chemicals based on lower water quality requirements, saving chemical costs. Furthermore, the intelligent design of the control unit eliminates the need for manual intervention throughout the dosing process, significantly reducing labor costs and avoiding errors that may arise from manual operation.

[0046] This utility model's swimming pool dosing device achieves precise control and automated management of swimming pool water quality through the coordinated operation of the aforementioned components. The independent placement and conical structure design of the storage tank 1 ensures the categorized storage and efficient utilization of various chemicals. The dynamic adjustment function of the metering pump 5 meets the dosing requirements under different water quality conditions. The design of the mixing chamber 6 and the stirring assembly 7 ensures uniform mixing of the chemicals. The intelligent monitoring and feedback mechanism of the control unit enables precise control of the entire dosing process. The overall structure is rationally designed and easy to operate, effectively solving the problems of insufficient dosing accuracy, low level of intelligence, and limited adaptability in existing technologies, thus meeting the needs of modern swimming pool management.

The main controller can be a conventional known device that can be controlled by a computer or other means. The detailed description of known functions and known components is omitted in the specific implementation of this disclosure. In order to ensure the compatibility of the device, the operating methods used are consistent with the parameters of commercially available instruments.

[0048] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model.
