In order to timely master the storage amount of rainwater in the primary water storage tank 4, the domestic water storage tank 9, the production water storage tank 13, the crop and greening water storage tank 15 and the qualified water storage tank 19, a water amount detection device is installed in the tank body in the embodiment, the water amount detection device can be realized in two modes, namely a resistance-type water level sensor is arranged in the tank body in the first mode, and a pressure sensor I is arranged at the bottom of the tank body in the second mode, and is an existing product. In the second embodiment, for example, the pressure sensors I are disposed at the bottoms of the primary water tank 4, the living water tank 9, the production water tank 13, the crop and greening water tank 15, and the qualified water tank 19. The device is also internally provided with a singlechip 11, the singlechip 11 is respectively electrically connected with the PH value sensor 5, the three-way valve and the pressure sensor I, and the working state of the three-way valve is controlled by level signals fed back to the singlechip 11 by the sensors, so that the automatic program control function is realized. The LCD1602 is connected with the singlechip 11 as a human-computer interaction interface; a WiFi module ESP8266 is connected with the single chip microcomputer 11, so that access of the Internet of things is realized, and the access is displayed on a small program; the buzzer is connected with the singlechip 11 and used for alarming and reminding.
The working process is as follows:
when in use, the device is fixedly arranged at a place with lower terrain, and is convenient for collecting rainwater and discharging sewage. When raining, the rainwater carries out prefiltration with great debris, impurity through quartz sand filter screen 1 earlier, and the rainwater after filtering collects to the center along the inner wall of water catch bowl 3 slope to flow into elementary storage water tank 4 in, PH value sensor 5 carries out the PH value to the internal water body of elementary storage water tank 4 and detects.
The method comprises the following steps: when elementary storage water tank 4 three-way valve is in the normally closed state, the rainwater is saved in elementary storage water tank 4, and singlechip 11 judges according to pH value sensor 5 detected value, and when the rainwater pH value in elementary storage water tank 4 exceeded the threshold value, the cost of purification was considered comprehensively, and it is unqualified water to deem these, and singlechip 11 control three-way valve opens the third port, arranges the rainwater in elementary storage water tank 4 in unqualified storage water tank 6 and discharges through delivery port 7. When the PH value of the rainwater in the primary water storage tank 4 is smaller than the threshold value, the rainwater is judged to be qualified water, the third port is opened by controlling the three-way valve for buffering for 30 seconds to ensure that the wastewater at the bottom of the primary water storage tank 4 is discharged, then the second port is opened, and the rainwater flows into the qualified water tank 19 in a proper condition to be filtered next step.
Step two: rainwater in the qualified water tank 19 enters the PP filter element filter 18, impurities such as suspended matters, particles, iron rust and the like in the rainwater are removed on the basis of primary filtration, the ecological water level is reached, and the rainwater can be used for irrigating crops or plants. Filtered rainwater firstly enters the crop and greening water storage tank 15 from a first-in first-out water gap, the pressure sensor I performs analog-to-digital conversion through the A/D converter adc0832, the converted signal is transmitted to the single chip microcomputer, the single chip microcomputer 11 displays data through the LCD1602, and then the data are transmitted to the small program through the WiFi module ESP8266 to be displayed. Since the single chip microcomputer 11 has set 2/3 of each water storage tank capacity as a threshold, when the level fed back by the pressure sensor I on the crops and greening water storage tanks 15 reaches the set threshold, the buzzer triggers an alarm, and displays the current water storage tank residual capacity in real time on a small program to inform the user that the current water quantity meets the use condition.
When the water storage tank 15 for crops and greening is full of water, the rainwater in the PP filter element filter 18 flows into the activated carbon filter 12 from the backwater water outlet, and pollutants such as decoloration, deodorization, dechlorination, organic matters, heavy metals and the like are removed on the basis of the previous stage of filtration, so that the grade of production water is reached, and the water can be used as production and processing water. Filtered rainwater enters the production water storage tank 13 from the first-in first-out water port, when the single chip microcomputer 11 reaches a set threshold value according to the level fed back by the pressure sensor I, an alarm is triggered through a buzzer, the residual capacity of the current water storage tank is displayed in real time on a small program, and a user is informed that the current water quantity meets the use condition.
When the production water storage tank 13 is full of water, rainwater in the activated carbon filter 12 flows into the ultrafiltration filter 8 from the lag water outlet, particles, colloids, bacterial cushions and high molecular organic substances in the water are removed on the basis of the previous stage of filtration, the grade of domestic water is reached, and the water can be used as daily domestic water. Filtered rainwater enters the domestic water storage tank 9 from the first-in first-out water port, when the single chip microcomputer 11 reaches a set threshold value according to the level fed back by the pressure sensor I, an alarm is triggered through the buzzer, the residual capacity of the current water storage tank is displayed in real time on a small program, and a user is informed that the current water quantity meets the use condition. A user can select different water storage tanks according to the requirement, and the valve at the first water outlet 16 is opened, so that the water storage tank can be used for irrigating crops; opening a valve at the second water outlet 14 to obtain production water for production and processing of a factory; the valve at the third 10 position of the water outlet is opened to obtain the domestic water, so that the domestic water can be used for daily life safely.
Step three: if the rainwater in the three tanks is not discharged in time within a set time (for example, within half an hour), judging whether the level generated by the pressure sensor I on the qualified water storage tank 19 is greater than a threshold value, and if the level is greater than the set threshold value, enabling the three-way valve to be in a normally closed state through the singlechip 11; when the level generated by the pressure sensor I of the primary water storage tank 4 is greater than the threshold value, the third port of the three-way valve is opened, part of water is discharged, and the device is prevented from being damaged by overflow of rainwater.
Step four: and when the level generated by the pressure sensor I of any one of the living water storage tank 9, the production water storage tank 13 and the crop and greening water storage tank 15 is less than the initial value, repeating the step one.
The above description is only the preferred embodiments of the present invention, and these embodiments are all based on the present invention, and the protection scope of the present invention is not limited thereto, and any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope of the present invention should be covered by the protection scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the protection scope of the claims.
