Description

Technical Field

[0001] The present invention belongs to the technical field of pipe network water supply, and particularly relates to a water quality detection device for a regulating water tank. Background Art

[0002] At present, most water tank products are rectangular water tanks, which are assembled on site with stamping plates and fixed internally with multiple tie bars. The height of the water tank generally does not exceed 3 meters. When it exceeds 3 meters, more tie bars are needed to strengthen the structural stability. The internal tie bars are crisscrossed, making it difficult to clean the water tank later. Automatic cleaning cannot be achieved, and manual cleaning poses safety hazards. In addition, rectangular water tanks occupy a large area. For many outdoor water tanks, there is enough height space, but the planar area is limited. It is difficult to coordinate the land use during the implementation of many rectangular water tanks, and ultimately the water tank volume has to be reduced.

[0003] Moreover, the existing water tanks cannot determine the pollution source, cannot automatically determine the cleaning cleanliness of the cleaner, and cannot judge the impact of the pollution degree on the water supply. As a result, when there is slight pollution in some areas of the water tank, targeted adjustments cannot be made to meet the emergency water supply demand. Therefore, the present invention proposes a water quality detection device and method for a regulating water tank. Summary of the Invention

The connecting pipe is communicated with the water outlet pipe.

[0011] Preferably, multiple groups of the water quality detection units are respectively arranged at one end of the drain pipe, the connecting pipe, the water outlet pipe close to the micro-power generation device, and one end of the water outlet pipe close to the cylindrical water tank.

[0012] Preferably, a method for detecting the water quality of a regulating water tank includes the following steps:

[0013] S1. The fourth water quality detection unit monitors the water quality data entering the water outlet pipe from the cylindrical water tank in real time, and sets the normal water quality value. , if the water quality data detected by the fourth water quality detection unit is less than or equal to , the water quality data is normal, and the cylindrical water tank operates normally;

[0030] It should be understood that terms such as "having", "comprising", and "including" used herein do not exclude the presence or addition of one or more other elements or their combinations.

[0032] Embodiment 1: Refer to Figures 1 - 5 , a water quality detection device for a storage tank, comprising a cylindrical water tank 4, a micro-power generation device 2, an automatic cleaning device, an attached-wall flow system, and a water quality detection system; the cylindrical water tank 4 is formed by splicing standard plates 3 with an arc shape; the attached-wall flow system includes an attached-wall pipe 5 and attached-wall pipe holes 22, and the total area of the attached-wall pipe holes 22 is larger than the cross-sectional area of the inlet pipe 7 to guide the water flow to flow along the side wall curve of the cylindrical water tank 4; the automatic cleaning device includes a three-dimensional cleaner 19, which is connected to an external high-pressure water source through a cleaning pipe 20 and is configured with an automatic control sliding structure in the longitudinal, lateral, and vertical directions; the water quality detection system is composed of multiple groups of water quality detection units for detecting the overall water quality in the cylindrical water tank 4; the micro-power generation device 2 is arranged at the bottom of the water tank, the micro-power generation device 2 is connected with a pipe network 1, and the micro-power generation device 2 is internally communicated with the cylindrical water tank 4 through a water outlet pipe 18; a guardrail 10 is provided at the top of the cylindrical water tank 4, two groups of symmetrical respirators 8 are provided at the top of the cylindrical water tank 4, and a ladder 21 is provided outside the cylindrical water tank 4; a drain pipe 16 is provided at the bottom of the cylindrical water tank 4, the drain pipe 16 is connected with a drain gate valve 15, and a cleaning pipe interface 9 is provided at one end of the cleaning pipe 20 placed outside the cylindrical water tank 4; an overflow pipe 11 is provided inside the cylindrical water tank 4, and an insect-proof net 14 is provided at the part of the overflow pipe 11 extending outside the cylindrical water tank 4.

[0033] The attached-wall pipe 5 is fixed to the inner wall of the cylindrical water tank 4 through a first fixing device 6, and the overflow pipe 11 is fixed to the inner wall of the cylindrical water tank 4 through a second fixing device 12 and a third fixing device 13;

[0034] A side-opening manhole 17 is further provided at the bottom of the cylindrical water tank 4;

[0035] In the present invention, a cylindrical water tank 4 is adopted for the water tank. It has a stable and safe structure without internal tie bars. The cylindrical water tank 4 can achieve a larger volume with the same floor area. The height of the cylindrical water tank 4 can be designed higher than that of the traditional rectangular water tank, making full use of the internal space and increasing the effective volume.

[0036] The cylindrical water tank 4 is made of assembled standard arc-shaped plates. The standard plate 3 is a large plate, which is convenient for installation, has fewer welds, and the standard plate 3 is simple to manufacture, reducing the manufacturing cost.

[0037] Since the cylindrical water tank 4 can be designed to have a higher height, taking full advantage of its height advantage, a micro-power generation device 2 is arranged below, which converts potential energy into electric energy without wasting resources.

[0038] The water inlet pipe 7 can achieve wall-attached flow of the water entering the water tank through the wall-attached flow system, improving the water inlet flow pattern of the water tank, ensuring water quality safety, reducing noise and vibration (the wall-attached flow flows downward along the curved surface structure of the side wall of the cylindrical water tank 4 through the wall-attached pipe holes 22, and the total area of all the holes of the wall-attached pipe holes 22 is larger than the cross-sectional area of the water inlet pipe 7). The design of the wall-attached pipe holes 22 on the wall-attached pipe 5 can disperse and reduce the impact of the water pressure of the water inlet pipe 7 on the wall-attached pipe 5, and can also prevent micro-vibration of the water inlet pipe 7 and the wall-attached pipe 5. At the same time, the wall-attached flow can slow down the impact of the water flow on the water tank body (multiple wall-attached pipe holes 22 are provided, which can divide the water flow pressure to avoid large water flow impact on the bottom and side walls of the water tank), extending the service life of the water tank. And the wall-attached flow discharges from top to bottom along the wall, which can wash away the sediment at the bottom of the water tank, making the sewage discharge more thorough during sewage discharge.

[0039] In addition, a one-way water flow component can be installed on the wall-attached pipe hole 22. The one-way water flow component can make the water in the wall-attached pipe 5 flow out through the one-way water flow component at the wall-attached pipe hole 22. When the water level in the cylindrical water tank 4 is too high, the one-way water flow component at the wall-attached pipe hole 22 can also ensure that water cannot flow into the wall-attached pipe 5 through the one-way water flow component, avoiding backflow or reverse mixing of water into the wall-attached pipe 5.

[0040] A backflow prevention valve is installed at the water inlet pipe 7 to isolate the outside from the inside of the water tank and avoid external pollution.

[0041] A three-dimensional cleaner 19 is arranged inside the water tank. By connecting to external high-pressure water, automatic cleaning of the inside of the water tank is realized. Due to no tie bars, dead-angle cleaning is achieved.

[0042] An automatic control sliding structure in the longitudinal, transverse and vertical directions is configured, saving electric energy and limited cleaning water consumption while expanding the cleaning area.

[0043] The micro-power generation device 2 (uses the water power of the water flowing through the water outlet pipe 18 of the water tank to drive a small water turbine to generate electricity. After storing the electric energy through the energy storage device, the stored electric energy can be partially supplied to the suction pump 26 or the cleaning device for use. It can convert the hydraulic potential energy and the kinetic energy of the water supply and drainage flow into electric energy, realizing partial self-supply of electric energy for the entire regulating water storage device, which is more conducive to energy conservation) is combined with the fully automatic cleaning device to perform cleaning work through the converted electric energy; it can also increase the water conveyance buffer and the water scale removal and anti-scaling structure, further avoiding the appearance of stagnant water at the bottom, and can regularly automatically remove the possible water scale in the water conveyance pipeline;

[0044] The main body of the cylindrical water tank 4 adopts an internal structure design of arc-shaped plates, which can improve the anti-water pressure performance of the water tank itself, extend the service life of the water tank, and combine this structural design with the attached wall pipe 5. For example, protrusions (such as spiral structures, trapezoids) are added inside the arc-shaped plates, etc., so that the attached wall pipe 5 is convenient to install, and can reduce the impact force of the water flow on the structure of the attached wall pipe 5, facilitate water inlet, and slow down the impact force of the water flow; at the same time, the shape of the attached wall pipe 5 can be designed into an S-shaped pipe structure or a spiral pipe structure, which can ensure that the attached wall pipe 5 is more attached and more stably connected to the inner wall of the cylindrical water tank 4;

[0045] By setting the insect-proof net 14, the drain valve and the anti-backflow structure, it is not only beneficial to the discharge of the cleaning sewage, but also can effectively prevent the backflow or secondary pollution of the cleaned sewage; at the same time, an improved design is made to realize that the drain valve automatically opens when the cleaning structure works.

[0046] Example 2: Refer to Figures 1 - 5 , which is basically the same as Example 1. Further: A water supply pipe 23 is provided inside the cylindrical water tank 4. The water supply pipe 23 is provided with a plurality of water supply ports 24 from top to bottom in sequence. One end of the water supply pipe 23 extending outside the cylindrical water tank 4 is connected to a suction pump 26. The other end of the suction pump 26 is connected to a connecting pipe 25. The connecting pipe 25 is communicated with the water outlet pipe 18; A plurality of groups of water quality detection units are respectively arranged at one end of the drain pipe 16, the connecting pipe 25, the water outlet pipe 18 close to the micro-power generation device 2, and the water outlet pipe 18 close to the cylindrical water tank 4. Among them, the water quality detection unit located on the drain pipe 16 is the first water quality detection unit, the water quality detection unit located on the connecting pipe 25 is the second water quality detection unit, the water quality detection unit located on the water outlet pipe 18 close to the micro-power generation device 2 is the third water quality detection unit, and the water quality detection unit located on the water outlet pipe 18 close to the cylindrical water tank 4 is the fourth water quality detection unit;

[0047] In the present invention, the water supply pipe 23 is provided with a plurality of water supply ports 24 from top to bottom in sequence, and each water supply port 24 can be opened and closed separately, so that the extraction of water layers at different positions can be realized;

[0048] The first water quality detection unit mainly detects the water discharged from the drain pipe 16. When it detects that the continuously discharged water is within the normal value, the drain pipe 16 can be closed to stop discharging water. The second water quality detection unit mainly detects the water quality of the water supplemented by the make-up water pipe 23. By cooperating with the make-up water inlets 24 at different positions, the water pollution source can be judged. The third water quality detection unit is the final water quality detection end. The fourth water quality detection unit mainly detects the water quality of the water input from the cylindrical water tank 4 into the outlet pipe 18.

[0049] A valve one 27 is provided on the outlet pipe 18, and a valve two 28 is provided on the connecting pipe 25.

[0050] The water quality detection unit is specifically a multi-parameter on-line water quality monitoring system. This device integrates sensors such as pH, turbidity, residual chlorine, dissolved oxygen, conductivity / TDS, and temperature to achieve multi-dimensional real-time monitoring of water quality.

[0051] Example 3: Refer to Figures 1 - 5 , which is basically the same as Example 2. Furthermore, a method for detecting the water quality of a storage water tank includes the following steps:

[0052] S1. The fourth water quality detection unit continuously monitors the water quality data of the water entering the outlet pipe 18 from the cylindrical water tank 4, and sets the normal water quality value . If the water quality data detected by the fourth water quality detection unit is less than or equal to , the water quality data is normal, and the cylindrical water tank 4 operates normally.

[0053] S2. If the water quality data detected by the fourth water quality detection unit is greater than , the water quality data is abnormal, and then the size relationship between the water quality data and the set limit value is further judged.

[0054] S3. Set the water quality pollution limit . If the water quality data is greater than the limit , the outlet pipe 18 is closed, and emergency water supply is provided by the make-up water pipe 23.

[0055] S4. If the water quality data is between the limit and the normal value , the make-up water pipe 23 and the outlet pipe 18 cooperate to supply water outward.

[0056] In step S3, during the emergency water supply process of the make-up water pipe 23, the third water quality detection unit continuously monitors the water quality. If the water quality data is abnormal, the make-up water pipe 23 is immediately closed.

[0057] It further includes: The water replenishing pipe 23 can determine the position of polluted water quality by enabling the water replenishing ports 24 at different positions and through real-time monitoring by the second water quality detection unit. If it is determined that the polluted water quality is in the lower layer, the drain pipe 16 is controlled to drain water synchronously, and water is replenished through the upper water replenishing port 24; if it is determined that the polluted water quality is in the upper layer, the lower water replenishing port 24 is controlled to replenish water.

[0058] In step S4, it further includes:

[0059] The water supply amounts of the water replenishing pipe 23 and the water outlet pipe 18 are dynamic values. If the water quality data approaches the normal value, the water outlet pipe 18 mainly supplies water and the water replenishing pipe 23 supplies water auxiliarily. If the water quality data is close to the limit value, the water replenishing pipe 23 mainly supplies water and the water outlet pipe 18 supplies water auxiliarily.

[0060] Specifically, set the normal water quality value :

[0061] If the water quality data detected by the fourth water quality detection unit is equal to or less than (clean water), the water quality data is normal and the water tank supplies water normally.

[0062] Set the water pollution limit :

[0063] i. If the water quality data is greater than (polluted water), it can be determined that the water quality is severely polluted and cannot be used, and the water outlet pipe 18 should be immediately closed.

[0064] I. The water replenishing pipe 23 can determine the position of polluted water quality by enabling the water replenishing ports 24 at different positions and through real-time monitoring by the second water quality detection unit.

[0065] II. If it is determined that the polluted water quality is in the lower layer, the drain pipe 16 is controlled to drain water synchronously, and water is replenished through the upper water replenishing port 24. After the emergency water supply ends, the three-dimensional cleaner 19 is mobilized to focus on and clean the lower part of the cylindrical water tank 4 for a long time.

[0066] III. If it is determined that the polluted water quality is in the upper layer, the lower water replenishing port 24 is controlled to replenish water. After the emergency water supply ends, the three-dimensional cleaner 19 is mobilized to focus on and clean the upper part of the cylindrical water tank 4 for a long time.

[0067] IV. If all the water collected by the water replenishing pipe 23 is polluted water or critical adjustable water quality after detection, the water replenishing pipe 23 stops supplying water, the drain pipe 16 discharges sewage comprehensively, and the three-dimensional cleaner 19 is mobilized to clean the cylindrical water tank 4 comprehensively for a long time.

[0068] Through the above method, when there is slight pollution in some areas of the cylindrical water tank 4, the present invention can intervene specifically, so as not to affect the emergency water supply demand.

[0069] Furthermore, in steps II, III, and IV, the drain pipe 16 needs to be opened, and at the same time, the first water quality detection unit in the drain pipe 16 is used to compare and detect whether the second water quality detection unit is operating normally.

[0070] ii. If the water quality data is between and If the water quality is between 0.01 and 0.17 (critical adjustable water quality), it can be judged that the water quality needs to be intervened before it can be used;

[0071] Critical adjustable water quality data : , the amount of water added is ;

[0072] Clean water quality data : , the amount of water added is ;

[0073] Water quality data after mixing , must meet the following requirements: ;

[0074] Based on the principle of conservation of mass, the total amount of pollution after mixing must meet the following requirements:

[0075]

[0076] Right now

[0077] In the above, a flow meter is provided on the connecting pipe 25 to monitor the amount of clean water added and provide real-time feedback to the controller, which drives the suction pump 26 or valve 28 to open and close, and accurately controls the amount of addition until the flow meter reading reaches the target. A liquid level sensor is provided in the cylindrical water tank 4 to monitor the water level (h) in real time, and the geometric parameters of the cylindrical water tank 4 (such as the cylindrical radius r) are input to calculate the volume by the formula ,pass , we can conclude ;

[0078] Furthermore, the cylindrical water tank 4 used in the present invention has no internal reinforcement, and compared with water tanks with complex shapes, it does not require three-dimensional modeling or multi-point liquid level sensor joint calibration;

[0079] By real-time calculation of intervention strategies under different water quality conditions, and linkage with the "water quality monitoring unit" and "automatic cleaning device" in the present invention, intelligent regulation is achieved.

[0080] Further, when the three-dimensional washer 19 cleans a certain area, the drain pipe 16 is in an open state, continuously discharging sewage. After the first water quality detection unit continuously detects that the water quality is within the normal range, it can be determined that the area is cleaned, and the three-dimensional washer 19 cleans other parts, thereby effectively saving energy and accelerating the cleaning efficiency.

[0081] The above embodiments only represent several implementation manners of the present invention, and their descriptions are relatively specific and detailed, but should not be construed as limiting the scope of the invention patent. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several modifications and improvements can be made. These are all equivalent modifications and evolutions made to the above embodiments based on the substantial technology of the present invention, and these all belong to the protection scope of the present invention.

If it is determined that the polluted water quality is in the lower layer, the drain pipe (16) is controlled to drain water synchronously, and the upper make-up water inlet (24) is used for make-up water; if it is determined that the polluted water quality is in the upper layer, the lower make-up water inlet (24) is controlled for make-up water.

9. A method for detecting the water quality of a storage water tank according to claim 8, characterized in that, In step S4, it further includes: The water supply amounts of the make-up water pipe (23) and the outlet pipe (18) are dynamic values. If the water quality data approaches the normal value, the outlet pipe (18) mainly supplies water and the make-up water pipe (23) supplies water as an auxiliary. If the water quality data is close to the limit value, the make-up water pipe (23) mainly supplies water and the outlet pipe (18) supplies water as an auxiliary.
