Description

The utility model relates to devices in the field of water treatment and can be used to analyze water parameters in swimming pools, automatically regulate and control its parameters.

The well-known “Analyzer of the list of swimming pool water parameters”, RF patent for utility model No. 84989, priority dated February 16, 2009, IPC G01N 35/00, which is the prototype of the claimed utility model. The prototype contains: an analyzer of chlorine content in water, an automatic compensator for water temperature, an analyzer of pH values (pH value) of water, and an analyzer of Redox potential (redox potential) with remote control units.

The disadvantages of the prototype is the impossibility of providing quality of the claimed technical result, which consists in improving the sanitary-epidemiological quality of water due to the fact that the analyzer of the list of swimming pool water parameters is defined only as a set of essential features with no connection between them, no relationship between these characteristics, and, in addition the disadvantages of the prototype are:

1. The influence of the human factor, requiring every morning before using the pool to correct “the pH value of water from 7.4 to 7.5 using a pH corrector, measure the Redox potential, adjust it ...”, as well as the need to replace the waste water with fresh dosed .

2. The need to regulate and control the flow of chlorine in water every morning at unacceptably high concentrations for humans “from 1 to 2 mg / l”, while, according to the sanitary-epidemiological rules and regulations of SanPiN 2.1.2.1188-03 ″ 2.1.2 . Design, construction and operation of residential buildings, public utilities, educational institutions, culture, recreation, sports. Swimming pools Hygienic requirements for the design, operation and quality of water. Quality control ″ (approved by the Chief State Sanitary Doctor of the Russian Federation on January 29, 2003), the amount of residual chlorine in the swimming pool should not exceed 0.5 mg / l, and for children's pools this concentration should not exceed 0.3 mg / l.

3. Insufficient accuracy of measuring water parameters during its analysis and water treatment due to the lack of galvanic isolation of the sensor electrical circuits: chlorine, pH, Redox potential, etc., which leads to errors in the operation of the analyzer of the list of swimming pool water parameters and incorrect dosing chemical reagents.

4. The absence in the analyzer of the list of water parameters of the module for controlling the dosage of the chemical reagent algaecide necessary to prevent the formation and growth of algae in the water of the swimming pool,

5. The absence in the analyzer of the list of water parameters of the module for controlling the dosage of the coagulant chemical reagent, necessary for combining small particles that inevitably accumulate in water, into larger ones with the aim of their subsequent retention in the water filter.

6. Absence in the analyzer of the list of water parameters of control modules and actuators: a control module and control the water level in the swimming pool, a control module for the circulation and feed pumps of the swimming pool (or solenoid valve), as well as an overdose control module for chemicals.

7. Lack of an Ethernet module for diagnostics and remote control of the analyzer of the list of water parameters via a local or global Internet.

8. Analysis of water parameters and dosing of necessary chemicals is not related to the operation of the pool circulation pump, i.e. there is no thorough mixing of chemicals in the entire volume of the swimming pool water, which contributes to the probable overdose of chemicals hazardous to human health.

The technical result of the claimed utility model is to increase the sanitary-epidemiological quality of the swimming pool water by automating the analysis and management of water treatment.

To achieve the technical result claimed in the utility model, the problem is solved in that the device comprises a free chlorine sensor in water, a water pH sensor, a Redox potential sensor, a water temperature sensor, a water level sensor in a swimming pool, chemical level sensors in their tanks, a control unit including a microcontroller, modules of signal amplifiers for sensors, a control and safety module for the circulation pump, a module for monitoring and maintaining the water level in the swimming pool, a control module the role and maintenance of water temperature in the swimming pool, a module for monitoring and dosing of chemical reagents, a real-time clock module, a remote control panel connection module, an Ethernet module for diagnosing and remotely controlling the device via a local or global Internet. All electrical circuits of the sensors are galvanically isolated. The analysis of water parameters and the dosing of chemical reagents is carried out only when the circulating water pump is running. The microcontroller is electrically connected to all sensors and all modules of the device, it processes the actual readings of the water parameters received from the sensors, compares them with the set values of the parameters and controls the modules of the actuators.

The utility model is illustrated by a figure.

A device for analyzing and controlling the water parameters of a swimming pool contains a free chlorine sensor 1 in water, a water pH sensor 2, a Redox potential sensor 3, a water temperature sensor 4, a water level sensor 5 in the swimming pool, chemical level sensors in their containers 6 , remote control panel 7, control unit including a microcontroller 8, a signal amplifier module for a chlorine 9 sensor in water, an amplifier module for a pH 10 sensor signal, an amplifier module for a Redox potential sensor 11 for water, a signal amplifier module yes a water temperature sensor 12, a signal amplifier module for a water level sensor 13 in a swimming pool, a signal amplifier module for chemical level sensors 14 in their tanks, a real-time clock module 15, a module for connecting a remote control panel 16, an Ethernet module 17 for diagnostics and remote control device through a local or global Internet, actuator modules (control and safety module for the water circulating pump 18, module for monitoring and maintaining the water level in lavatelnom basin 19, the control module and maintaining temperature of water in the swimming pool 20, the control module and dispensing of chemical reagents 21). The electrical circuits of all sensors are galvanically isolated. The microcontroller 8 is electrically connected to all sensors and all modules of the device.

The device operates as follows.

Signals of actual readings of swimming pool water parameters from sensors (free chlorine in water sensor 1, water pH sensor 2, Redox potential sensor 3, water temperature sensor 4, water level sensor in the swimming pool 5), as well as from chemical level sensors in their tanks 6, they enter the control unit for amplifiers of sensor signals: chlorine in water 9, water pH 10, Redox potential of water 11, water temperature 12, water level in the swimming pool 13, levels of chemicals in their tanks 14. Microcontroller 8 processes facts The testimony of these parameters, compares them with the set values of the parameters and controls the modules of the actuators (control and safety module for the circulation pump 18, module for monitoring and maintaining the water level in the swimming pool 19, module for monitoring and maintaining the water temperature in the swimming pool 20, control module and chemical dosing 21). Actuator modules turn actuators on and off: circulation pump, feed pump, solenoid valve, chemical dosing pumps, automatic temperature controller, heat exchangers, etc. The analysis of the actual readings of the water parameters and the dosing of chemicals in the water of the swimming pool is carried out only when the circulating pump is running, thereby ensuring high-quality mixing of chemicals in the entire water volume of the swimming pool, which eliminates the likelihood of an overdose of chemicals. The control and safety module of the water circulation pump 18 controls the operation of this pump, avoiding the conditions of current overloads and in the absence of water flow through this pump. The module for monitoring and maintaining the water level in the swimming pool 19 controls the operation of the feed pump (or solenoid valve), preventing it from operating under current overload conditions and in the absence of water flow through this pump (or solenoid valve), it maintains the set water level in the swimming pool pool. Dosing of chemical reagents is carried out according to automatically calculated values, based on the specified parameters of the swimming pool (pool volume, estimated number of people in the pool, concentration of chemicals, etc.), or in accordance with a predetermined volume of dosing of chemicals (ml / day). The module for monitoring and dosing of chemical reagents 21 (chlorine, active oxygen, algaecide, coagulant, acid, etc.) excludes the possibility of overdosing these chemicals in the swimming pool water. In the event of an emergency failure of one or several sensors, it is possible to dispense chemical reagents taking into account the real-time clock 15 and signal it through the connection module of the remote control panel 16 with the output of information to the remote control panel 7 and through the Ethernet module 17 for diagnostics and remote device control via local or global Internet. In the case of lowering the levels of chemical reagents in their tanks below the permissible values, this is signaled through the connection module of the remote control panel 16 with the output of information to the remote control panel 7, which allows for timely replenishment or replacement of chemical tanks. Remote control panel 7 can be removed and installed in a separate technical room, allows you to monitor and control the operation of the device. A service organization that installs a device for analyzing and managing the water parameters of a swimming pool, or service personnel of a swimming pool, can receive information about the device’s operation and remotely control it thanks to the Ethernet module 17 for diagnostics and remote control of the device via a local or global Internet. Thus, the claimed utility model allows to solve the problem of improving the sanitary-epidemiological quality of the water of a swimming pool by automating the analysis and management of water treatment.
