DETAILED DESCRIPTION

[0050] Exemplary embodiments will be described in detail herein, examples of which are shown in the accompanying drawings. When the following description refers to the drawings, the same numbers in different drawings represent the same or similar elements unless otherwise indicated. The implementations described in the following exemplary embodiments do not represent all implementations consistent with the present application. Instead, they are merely examples of devices and methods consistent with some aspects of the present application as detailed in the appended claims.

[0051] Figure 1 A schematic diagram of a cleaning method for a surge tank provided in this application, such as Figure 1 As shown, the specific application scenario of this application is to clean the surge tank. The surge tank is a component in the secondary water supply system, which also includes the surge tank and the control system. The surge tank needs to be cleaned regularly to prevent water pollution.

[0052] In the prior art, the manual cleaning method of the pressure stabilizing tank has the problem of insufficient cleaning time and long residual stain time, which affects the quality of water used by residents.

[0053] The pressure stabilizing tank cleaning method provided in the present application sets a preset time period, and performs a test on whether the water quality in the pressure stabilizing tank meets the standard every time the preset time period is reached. The pressure stabilizing tank is cleaned in time when the water quality does not meet the standard. This technical means solves the problem of manual cleaning of the pressure stabilizing tank, which has the problem of insufficient cleaning time and long residual stain time.

[0054] The technical solution of the present application and how the technical solution of the present application solves the above-mentioned technical problems are described in detail below with specific embodiments. The following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be repeated in some embodiments. The embodiments of the present application will be described below in conjunction with the accompanying drawings.

[0055] Figure 2 Schematic diagram of the process of cleaning the pressure-surge tank provided in this application Figure 1 The pressure stabilizing tank cleaning method is applied to a control system of a water supply system, and the water supply system also includes a pressure stabilizing tank and a water quality detection device.

[0056] like Figure 2 As shown, the method includes:

[0057] S201, whenever a preset time period is reached and it is determined that the pressure stabilizing tank stops working, the water quality of the water in the pressure stabilizing tank is tested by the water quality testing device.

[0058] Among them, the preset time period can be set as a water supply trough period to minimize the interference of water quality detection on water supply. The preset time period can be selected according to the characteristics of residential water use. For example, the 24 hours a day are divided into three water supply characteristic periods, the first water supply period is from 0:00 to 9:00, the second water supply period is from 9:00 to 16:00, and the third water supply period is from 16:00 to 24:00. Each period includes a water supply peak period and a water supply trough period. The first water supply period includes a water supply peak period from 7:00 to 8:00 and a water supply trough period from 2:00 to 3:00. The second water supply period includes a water supply peak period from 12:00 to 13:00 and a water supply trough period from 14:00 to 15:00. The third water supply period includes a water supply peak period from 20:00 to 21:00 and a water supply trough period from 23:00 to 24:00. Then the preset period can be from 2:00 to 3:00, 14:00 to 15:00, and 23:00 to 24:00 every day.

[0059] When the preset time period is reached, the pressure stabilizing tank needs to stop working before the water quality test can be performed. If the pressure stabilizing tank does not stop working, the water quality test will not be performed temporarily.

[0060] The water quality detection device can be used to detect water turbidity, residual chlorine, pH (Pondus Hydrogenii, PH for short), temperature, etc. Correspondingly, the water quality detection device can be provided with one or more of the following: residual chlorine electrode, turbidity electrode, PH electrode and temperature probe.

[0061] The water quality detection device can be arranged inside the pressure stabilizing tank, or in other closed devices connected to the pressure stabilizing tank. The arrangement position of the water quality detection device can be arranged according to actual needs, and this embodiment does not limit it, as long as the water in the pressure stabilizing tank can be detected by the water quality detection device.

[0062] S202. When it is determined according to the detection data of the water quality detection device that the water quality in the pressure stabilizing tank does not meet the standard, the following steps are performed at least once to clean the pressure stabilizing tank: control the pressure stabilizing tank to drain water, and replenish water to the pressure stabilizing tank after drainage.

[0063] The detection data may include one or more of the following: turbidity, residual chlorine, pH, temperature, etc.

[0064] The water quality does not meet the standard, which means that the test data does not meet any standard condition, or the test data does not meet all standard conditions. The standard conditions may include one or more of the following: turbidity meets the standard, residual chlorine meets the standard, pH meets the standard, temperature meets the standard, etc. For example, if the test data includes turbidity and residual chlorine, it can be determined that the water quality does not meet the standard when the turbidity does not meet the standard or the residual chlorine does not meet the standard, or it can be determined that the water quality does not meet the standard when both the turbidity and the residual chlorine do not meet the standard.

[0065] The steps described control the drainage of the surge tank and replenish water to the surge tank after drainage, with the purpose of cleaning the surge tank. The steps can be performed multiple times to improve the cleaning effect of the surge tank.

[0066] The method for cleaning the pressure stabilizing tank provided in this embodiment sets a preset time period, and performs a test on whether the water quality in the pressure stabilizing tank meets the standard every time the preset time period is reached. The technical means of cleaning the pressure stabilizing tank in time when the water quality does not meet the standard can clean the pressure stabilizing tube in time, solving the problem of the method of cleaning the pressure stabilizing tank by manual operation, which has the problem of insufficient cleaning and long residual stain time. More importantly, it can be performed during the preset time period (water supply trough period) to reduce the interference with normal water supply.

[0067] In some embodiments, before step S201, the pressure regulating tank cleaning method further includes:

[0068] Step 1: Count the historical water supply flow and water supply period of the water supply system.

[0069] The water supply system is used to supply water to residents. The water supply period of the water supply system can be divided into peak water supply period and valley water supply period according to the historical water supply flow. In order to reduce the interference of water quality testing and cleaning of the pressure stabilizing tank on water supply, it is necessary to test the water quality of the pressure stabilizing tank and clean the pressure stabilizing tank during the valley water supply period.

[0070] Step 2: When the historical water supply flow rate is less than or equal to the preset water supply flow rate, the water supply period corresponding to the historical water supply flow rate is used as the preset period.

[0071] Among them, the preset water supply flow rate can be set according to actual needs.

[0072] Furthermore, after the water supply system has been running for a period of time, the historical water supply flow of the water supply system during this period can be counted, and a historical water supply curve can be formed according to the historical water supply flow. Then, the peak water supply period and the valley water supply period can be accurately divided based on the historical water supply curve and the preset water supply flow.

[0073] The method provided in this embodiment is used to determine the water supply low period, so as to perform water quality detection and cleaning on the pressure-stabilizing tank during the water supply low period, reduce the interference of water quality detection and cleaning of the pressure-stabilizing tank on the water supply, and improve the water supply effect of the water supply system.

[0074] In some embodiments, after step S202, the surge tank cleaning method further includes:

[0075] Step 1: re-test the water quality of the water in the pressure stabilizing tank by the water quality detection device. If the water quality does not meet the standard, clean the pressure stabilizing tank again until the water quality meets the standard.

[0076] That is to say, in order to ensure the cleaning effect, after the pressure regulating tank is cleaned once or multiple times, the water quality in the pressure regulating tube is re-tested by the water quality detection device. If it is determined that the water quality meets the standard after re-testing, it means that the cleaning effect is good and the cleaning purpose is achieved. If it is determined that the water quality still does not meet the standard after re-testing, the pressure regulating tank needs to be cleaned again. When cleaning the pressure regulating tank again, the steps for cleaning the pressure regulating tank as described in step S202 can be performed, or other methods can be used to clean the pressure regulating tank, which is not limited in this embodiment.

[0077] To ensure the effectiveness of the second cleaning, the water quality in the pressure regulating tank can be retested after the second cleaning.

[0078] Optionally, if the water quality in the pressure stabilizing tank still does not meet the standard after the pressure stabilizing tank has been cleaned more than a preset number of times, an alarm is required to remind maintenance personnel to check the water supply system in time.

[0079] The method provided in this embodiment cleans the pressure stabilizing tank and retests the water quality in the pressure stabilizing tank when the preset time period (water supply low period) is reached. If the water quality does not meet the standard, the pressure stabilizing tank is cleaned again until the water quality meets the standard. The purpose of this is to ensure the cleaning effect of the pressure stabilizing tank and prevent the pressure stabilizing tank from being inadequately cleaned. In addition, since it is performed during the water supply low period, it can reduce interference with normal water supply.

[0080] In some embodiments, the water supply system further comprises a first electric valve. The first electric valve may be a three-way electric valve. The first port of the first electric valve is connected to the water supply main pipeline of the water supply equipment in the water supply system, the second port is connected to the pressure stabilizing tank, and the third port is a drain port. The water supply port of the pressure stabilizing tank is connected to the water inlet of the water quality detection device, and the water inlet is provided with a second electric valve.

[0081] Before the water quality of the water in the pressure stabilizing tank is detected by the water quality detection device in step S201, the pressure stabilizing tank cleaning method further includes:

[0082] Step 1: Every time the preset time period is reached, the first port, the second port and the third port of the first electric valve are controlled to be closed, and the second electric valve is controlled to be opened, so that the water in the pressure regulating tank enters the water quality detection device from the water inlet.

[0083] Among them, the preset time period can be set as a water supply trough period to minimize the interference of water quality detection on water supply. The preset time period can be selected according to the characteristics of residential water use. For example, the 24 hours a day are divided into three water supply characteristic periods, the first water supply period is from 0:00 to 9:00, the second water supply period is from 9:00 to 16:00, and the third water supply period is from 16:00 to 24:00. Each period includes a water supply peak period and a water supply trough period. The first water supply period includes a water supply peak period from 7:00 to 8:00 and a water supply trough period from 2:00 to 3:00. The second water supply period includes a water supply peak period from 12:00 to 13:00 and a water supply trough period from 14:00 to 15:00. The third water supply period includes a water supply peak period from 20:00 to 21:00 and a water supply trough period from 23:00 to 24:00. Then the preset period can be from 2:00 to 3:00, 14:00 to 15:00, and 23:00 to 24:00 every day.

[0084] After the first port and the second port of the first electric valve are closed, the pressure stabilizing tank stops taking in water. After the third port of the first electric valve is closed, the pressure stabilizing tank stops draining water. After the second electric valve is controlled to open, the water in the pressure stabilizing tank enters the water quality detection device.

[0085] The method provided in this embodiment describes that the flow direction of water in the pressure-suppressing tank and the amount of water in the pressure-suppressing tank can be controlled by controlling the closing and opening of each port of the first electric valve. When testing the water quality of the pressure-suppressing tank, the water in the pressure-suppressing tank can be controlled to enter the water quality testing device by controlling the closing of each port of the first electric valve and controlling the opening of the second electric valve. The water quality testing device is used to test the water quality of the incoming water. In this way, every time a preset time period (a period of low water supply) is reached, the first electric valve and the second electric valve are controlled, and the water quality test of the water in the pressure-suppressing tank can be achieved without human intervention, which improves the efficiency of the water quality test of the pressure-suppressing tank and also improves the efficiency of cleaning the pressure-suppressing tank.

[0086] In some embodiments, the control system further includes a first pressure sensor and a second pressure sensor, wherein the first pressure sensor is disposed in the water supply main pipeline and the second pressure sensor is disposed at the inlet of the pressure stabilizing tank. The first pressure sensor is used to collect the pressure of water in the water supply main pipeline and the second pressure sensor is used to collect the pressure of water at the inlet of the pressure stabilizing tank.

[0087] Before the water quality of the water in the pressure stabilizing tank is detected by a water quality detection device in step S201, the pressure stabilizing tank cleaning method further includes:

[0088] Step 1: every time the preset time period is reached, the first port and the second port of the first electric valve are controlled to be opened and the third port is controlled to be closed, and the pressures collected by the first pressure sensor and the second pressure sensor are controlled to be equal to the preset pressure.

[0089] Among them, the preset pressure can be set according to the community water supply design flow, head requirements, etc.

[0090] Before the second electric valve is opened, the switch state of the first electric valve is controlled to be that the first port is open and the second port is open, and the third port is closed, and the pressure collected by the first pressure sensor is set to be equal to the preset pressure to ensure normal water supply in the water supply main pipeline. At this time, when the pressure collected by the second pressure sensor is controlled to be equal to the preset pressure, the pressure stabilizing tank plays a role in balancing the water supply pressure.

[0091] The method provided in this embodiment controls the water inlet pressure of the pressure-stabilizing tank and the water pressure in the water supply main pipeline to be equal to a preset pressure, so that the pressure-stabilizing tank can balance the water supply pressure. When the water supply pressure fluctuates, the water supply pressure can be stabilized, so that the water supply pressure can be maintained stable even during peak water supply periods.

[0092] In some embodiments, the water supply system further comprises a water inlet device, and the water inlet device is provided with a water tank.

[0093] When it is determined that the water quality in the surge tank does not meet the standard, the surge tank cleaning method further includes:

[0094] Step 1: Send an alarm message for cleaning the water tank.

[0095] The water quality of the water in the pressure-suppressing tank is equivalent to the water quality of the water in the water tank. When it is detected that the water quality of the water in the pressure-suppressing tank is not up to standard, it indicates that the water quality of the water in the water tank is also not up to standard. Therefore, it is necessary to issue an alarm message for cleaning the water tank so as to clean the water tank. The alarm message can be issued by display, playback or other means, which is not limited in this embodiment.

[0096] Step 2: After detecting that the water tank is cleaned, detecting the water quality of the water in the water tank.

[0097] After the water tank is cleaned, the water quality of the water in the water tank is detected by the water quality detection device.

[0098] First, the water in the water tank is controlled to flow to the water quality detection device. Specifically, the first port and the second port of the first electric valve are adjusted to be open, the third port is closed, and the second electric valve is controlled to be open, at which time the water in the water tank flows to the water quality detection device. The water quality of the water in the water tank is then detected by the water quality detection device to determine the cleaning result of the water tank.

[0099] Optionally, if the test result of the water quality detection device is still that the water quality does not meet the standard, an alarm message for cleaning the water tank can be issued again, and after detecting that the water tank is cleaned, the water quality of the water in the water tank can be tested until the water quality of the water in the water tank meets the standard.

[0100] The method provided in this embodiment determines that the water quality of the water in the water tank does not meet the standard by detecting that the water quality in the pressure regulating tank does not meet the standard when the preset time period (water supply low period) is reached, and sends an alarm message for cleaning the water tank to remind maintenance personnel to clean the water tank in time. After detecting that the cleaning of the water tank is completed, the water quality of the water in the water tank is detected again to determine the cleaning result of the water tank. The method provided in this embodiment is performed in the preset time period (water supply low period), reducing interference with normal water supply.

[0101] In some embodiments, the water inlet device further comprises a water inlet portion, and the water inlet of the water tank is connected to the water inlet portion. The water inlet of the water tank is provided with a third electric valve.

[0102] Before the water tank is detected to be cleaned, the surge tank cleaning method further includes:

[0103] Step 1: Control the opening of the third electric valve to maintain the water level in the water tank at a preset water level during the current water supply period.

[0104] The preset water level is lower than the normal water level in the water tank corresponding to the current water supply period. The normal water level refers to the water level in the water tank during normal water supply, which can be obtained through historical water supply data.

[0105] The preset water level can be set according to actual needs. For example, the preset water level is set to (V01, V02, V03) during each water supply peak period, and the preset water level is set to (V11, V12, V13) during each water supply valley period. The control system also includes a liquid level sensor, which is arranged in the water tank. The water level of the water tank can be detected by the liquid level sensor. Before the water supply system supplies water, the third electric valve is first opened to fill the water tank with water to the preset water level of the current water supply period.

[0106] Furthermore, the opening of the third electric valve can be controlled in combination with the above-described step of controlling the water inlet pressure of the pressure stabilizing tank and the water pressure in the water supply main pipeline to be equal to the preset pressure, so as to control the water level of the water tank while maintaining the function of balancing the water supply pressure of the pressure stabilizing tank.

[0107] The method provided in this embodiment, when the preset time period (water supply low period) is reached, controls the water level of the water tank to the preset water level, and the preset water level is lower than the normal water level, so that when water quality testing and equipment cleaning (such as water tank cleaning, pressure tank cleaning) are performed, water resource waste can be reduced, the cost of water quality testing and equipment cleaning can be reduced, and the water supply effect of the water supply system can be improved. In addition, it is carried out during the water supply low period, which reduces the interference with the normal water supply.

[0108] In some embodiments, the water quality detection device includes a circulation pool. Preferably, the circulation pool is arranged outside the pressure-surge tank so as to be able to perform water quality detection of any device.

[0109] The circulation pool is provided with one or more of the following water quality detectors: a residual chlorine electrode, a turbidity electrode, a pH electrode and a temperature probe.

[0110] When there are multiple types of water quality detectors, determining in step S202 that the water quality in the pressure stabilizing tank does not meet the standards based on the detection data of the water quality detection device includes:

[0111] Step 1: Determine, based on the detection data of any water quality detector, that the water quality in the pressure stabilizing tank does not meet the standard.

[0112] When the water quality detector includes a residual chlorine electrode, the detection data includes residual chlorine. When the water quality detector includes a turbidity electrode, the detection data includes turbidity. When the water quality detector includes a pH electrode, the water quality detector includes pH. When the water quality detector includes a temperature probe, the water quality detector includes temperature.

[0113] If it is determined that the water quality does not meet the standard according to the detection data of any water quality detector, the pressure regulating tank is cleaned.

[0114] In the above embodiment, when the water quality of the water in the water tank is detected by the water quality detection device, the detection data of each water quality detector is obtained. Optionally, if it is determined that the water quality of the water in the water tank does not meet the standard according to the detection data of any water quality detector, it is determined that the water quality of the water in the water tank does not meet the standard and needs to be cleaned again. When it is determined that the water quality of the water in the water tank meets the standard according to the detection data of each water quality detector, it is determined that the water quality of the water in the water tank meets the standard and does not need to be cleaned again.

[0115] The water quality detector may also include other types of water quality detectors, which are not limited in this embodiment.

[0116] In some embodiments, when step S202 determines that the water quality does not meet the standard, the following steps are performed at least once to clean the pressure-stabilizing tank: control the pressure-stabilizing tank to drain, and replenish water to the pressure-stabilizing tank after draining. Specifically, first close the second electric valve, then open the second port and the third port of the first electric valve, and close the first port of the first electric valve. When the pressure at the outlet of the pressure-stabilizing tank is 0, it indicates that all the water in the pressure-stabilizing tank is discharged, and the first cleaning is completed. Then control the first port and the second port of the first electric valve to open, and the third port to close. At this time, the pressure of the water in the water supply main pipeline is greater than the pressure of the water at the water inlet of the pressure-stabilizing tank. Continue to replenish water into the pressure-stabilizing tank.
