Description

Technical Field

[0001] This application relates to the technical field of secondary water supply treatment, and particularly to a pollution-free automatic sampling and detection device for secondary water supply. Background Art

[0002] As a key component of the urban water supply system, secondary water supply mainly serves to make up for the insufficient pressure of the municipal water supply network. Specifically, it stores and pressurizes tap water with the help of water tanks or pools, and then supplies water to high-rise buildings or users at the end of the water supply network. However, there are potential water quality safety hazards in the process of secondary water supply. It is necessary to regularly detect the water quality in the water tank to ensure the safety of water supply.

[0003] To solve the problem of water quality detection in secondary water supply, the prior art usually installs fixed water quality detection components inside the water tank. However, this method has obvious defects:

[0004] (1) The number of detection points is small, usually only arranged at the edge of the water body in the water tank, and it is impossible to comprehensively detect the water bodies at various places in the water tank, resulting in difficulty in ensuring the accuracy of the detection results.

[0005] (2) The detection components are immersed in water for a long time, and impurities in the water are easily attached to the detection components, which will also affect the accuracy of the detection results.

[0006] (3) The existing fixed water quality detection components only have the function of water quality detection, and cannot exclude the stagnant water at the bottom of the water tank, nor can they perform on-line cleaning of the bottom of the water tank.

[0007] Therefore, it is urgent to develop a new type of pollution-free automatic sampling and detection device for secondary water supply to overcome the deficiencies of the prior art and achieve more accurate water quality detection and better water tank maintenance. Summary of the Invention

Detailed implementation manners

[0037] The following further elaborates on this application Figures 1-7 in conjunction with the attached drawings.

[0038] An embodiment of this application discloses a pollution-free automatic sampling and detection device for secondary water supply. Referring to Figures 1-7 , the pollution-free automatic sampling and detection device for secondary water supply includes a water tank 1, an isolation mechanism 2, a detection mechanism 3, a cleaning mechanism 4, and a control mechanism.

[0039] The water tank 1 is provided with a water inlet 11, a water outlet 12, a cleaning outlet 13, and a cleaning inlet 14. The water outlet 12 is communicated with the inlet of a water supply pump 6, and the water supply pump 6 is used for supplying water to users. The water outlet 12, the cleaning outlet 13, and the cleaning inlet 14 are all located at the lower end of the water tank 1. The cleaning outlet 13 and the cleaning inlet 14 are oppositely arranged and are both located below the water outlet 12.

[0040] The isolation mechanism 2 includes an isolation plate 21, a plurality of isolation valves 22, and a lifting drive member 23. The isolation plate 21 is slidably arranged in the water tank 1 and is parallel to the bottom surface of the water tank 1. A plurality of isolation holes are formed in the isolation plate 21, and each of the isolation valves 22 is installed in a corresponding isolation hole. The lifting drive member 23 is connected to the isolation plate 21 and is used for driving the isolation plate 21 to lift.

[0041] The detection mechanism 3 includes a folding rod 31 and a number of water quality detection components 32. The folding rod 31 is formed by sequentially hinging a number of struts 311 end to end. One end of it is connected to the inner top surface of the water tank 1, and the other end is connected to the partition plate 21. Each of the water quality detection components 32 is respectively installed on each strut 311 of the folding rod 31. In this embodiment, the water quality detection component 32 can perform real-time automatic sampling detection and can obtain the detection result in real time. The water quality detection component 32 can include a COD sensor, a turbidity sensor, etc.

[0042] The cleaning mechanism 4 includes a cleaning pump 41 and a sewage discharge pipe 42. The inlet of the cleaning pump 41 is communicated with the cleaning outlet 13, and the outlet of the cleaning pump 41 is communicated with the cleaning inlet 14 or one end of the sewage discharge pipe 42.

[0043] The control mechanism is communicatively connected to the isolation mechanism 2, the detection mechanism 3, the cleaning mechanism 4 and the alarm component. Every preset time, the control mechanism controls the partition plate 21 to move to a preset position to isolate the water tank 1 into a cleaning space and a detection space, and enables the cleaning mechanism to clean the bottom of the water tank 1, and / or uses the detection mechanism 3 to perform water quality detection on the water stored in the detection space. When the water quality does not meet the standard, the alarm component is started to prompt the staff to handle it.

[0044] When using the stored water in the water tank 1 normally, water quality detection is carried out regularly. During the detection, the lifting drive member 23 starts to work, driving the partition plate 21 to slowly move downward in the water tank 1. At this time, each isolation valve 22 on the partition plate 21 is in an open state, so that the water in the water tank 1 can freely flow above the partition plate 21. When the lifting drive member 23 drives the partition plate 21 to move to a preset height from the bottom of the water tank 1, it stops moving. Subsequently, each isolation valve 22 is closed, and the partition plate 21 divides the water tank 1 into two non-communicating upper and lower parts. Among them, the upper part is the detection chamber, and the lower part is the cleaning chamber. At this time, the cleaning pump 41 of the cleaning mechanism 4 is started, and the water body at the bottom of the water tank 1 is pumped out from the cleaning outlet 13 and then re-enters the bottom of the water tank 1 from the cleaning inlet 14 to form a circulating water flow. During the water flow circulation process, the bottom of the water tank 1 is continuously washed, so that the impurities attached to the inner wall of the water tank 1 are separated from the inner wall of the water tank 1. After circulating for a period of time, the outlet of the cleaning pump 41 is switched to be communicated with the sewage discharge pipe 42 to discharge the sewage containing impurities from the water tank 1. Then, at least one isolation valve 22 is opened to allow the relatively clean water above the partition plate 21 to enter below the partition plate, and then each isolation valve 22 is closed again, and the above cleaning steps are repeated. In this way, the preset number of cleaning times is performed to ensure that the bottom of the water tank 1 is fully cleaned. After completing the preset number of cleaning times, each isolation valve 22 is opened again, and the lifting drive member 23 drives the partition plate 21 to slowly move upward above the water body.

[0045] When the partition plate 21 moves to the bottom of the water tank 1, the folding rod 31 unfolds, and the water quality detection components 32 installed on each strut 311 of the folding rod 31 are distributed to different positions in the water tank 1 accordingly. At this time, the water quality detection components 32 are activated to detect the water quality of the water body in the water tank 1. When the partition plate 21 moves above the water surface, the folding rod 31 folds, and the water quality detection components 32 are all located above the water body, avoiding being soaked by the water body and preventing impurities in the water from adhering to the water quality detection components 32.

[0046] The technical effects of the above technical solution include:

[0047] (1) The folding rod 31 of the detection mechanism 3 is formed by sequentially hinging a plurality of struts 311 end to end, and the water quality detection components 32 are respectively installed on each strut 311. When the partition plate 21 moves to the bottom of the water tank 1, the folding rod 31 unfolds, and the water quality detection components 32 can be distributed to different positions in the water tank 1, changing the situation in the prior art where the detection points are only arranged at the edge of the water body in the water tank 1, and enabling comprehensive detection of the water body at various locations in the water tank 1, greatly improving the accuracy of the detection results;

[0048] (2) When the partition plate 21 moves above the water surface, the folding rod 31 folds, and the water quality detection components 32 are all located above the water body, avoiding the detection components being soaked in water for a long time and preventing impurities in the water from adhering to the detection components, thereby ensuring the accuracy of the detection results;

[0049] (3) The cleaning mechanism 4 includes a cleaning pump 41 and a sewage pipe 42. By controlling the connection of the inlet and outlet of the cleaning pump 41, a circulating water flow can be formed in the water body at the bottom of the water tank 1, continuously flushing the bottom of the water tank 1, causing the impurities attached to the inner wall of the water tank 1 to detach from the inner wall of the water tank 1, and discharging the sewage containing impurities from the water tank 1. Moreover, it can be cleaned repeatedly for a preset number of times to ensure that the bottom of the water tank 1 is fully cleaned, and during the cleaning process, it does not affect the normal secondary water supply.

[0050] In one embodiment, please refer to Figure 1 , a float valve 16 is further provided in the water tank 1. The float valve 16 is located in the water tank 1, and its inlet is connected to the water inlet 11. The connection between the float valve 16 and the water inlet 11 enables automatic control of the water inlet according to the change of the water level in the water tank 1. When the water level in the water tank 1 drops, the float ball drops with the water level, driving the valve to open, and water flows into the water tank 1 from the water inlet 11; when the water level rises to a certain height, the float ball floats up to close the valve and stop the water inlet. This ensures that an appropriate water level is always maintained in the water tank 1, avoiding water overflow due to too high a water level or affecting the normal water supply due to too low a water level, and ensuring the stable operation of the secondary water supply system.

[0051] In one embodiment, please refer to Figure 1, a perforation is provided on the upper end surface of the water tank 1. The isolation mechanism 2 further includes a vertical rod 24 which is slidably inserted into the perforation. One end of the vertical rod 24 is fixedly connected to the isolation plate 21, and the lifting driving member 23 is connected to the other end of the vertical rod 24 and is used to drive the vertical rod 24 to move up and down. In this embodiment, the vertical rod 24 is slidably inserted into the perforation on the upper end surface of the water tank 1, providing accurate guidance for the lifting of the isolation plate 21. This enables the isolation plate 21 to move vertically and stably up and down in the water tank 1 under the drive of the lifting driving member 23.

[0052] In one embodiment, please also refer to Figure 1 , Figure 6 and Figure 7 , the lifting driving member 23 includes an equipment box 231, a mounting plate 232, a winding wheel 233, a pulling rope 234 and a rotation driving member 235. The equipment box 231 is fixed to the upper end of the water tank 1, the mounting plate 232 is fixed to the equipment box 231, the winding wheel 233 is rotatably arranged on the mounting plate 232, the pulling rope 234 is wound around the winding wheel 233, the free end of the pulling rope 234 is connected to the other end of the vertical rod 24, and the rotation driving member 235 is connected to the winding wheel 233 and is used to drive the winding wheel 233 to rotate. In this embodiment, the rotation driving member 235 drives the winding wheel 233 to rotate, precisely controlling the up and down movement of the vertical rod 24 by winding and unwinding the pulling rope 234, and further accurately controlling the lifting height of the isolation plate 21. The overall density of the isolation plate 21 is much greater than that of water. Therefore, even if the isolation plate 21 is completely immersed in water, its gravity is much greater than the buoyancy, so it can ensure that the pulling rope 234 is always in a taut state.

[0053] In one embodiment, please refer to Figure 1 , Figure 6 and Figure 7 , the rotation driving member 235 includes a first rotation driving motor 2351, a driving pulley 2352, a driven pulley 2353 and a synchronous belt 2354. The output end of the first rotation driving motor 2351 is fixedly connected to the driving pulley 2352, the driven pulley 2353 is coaxially fixed to the winding wheel 233, and the synchronous belt 2354 is closed and its two ends are respectively wound around the driving pulley 2352 and the driven pulley 2353. In this embodiment, the first rotation driving motor 2351 drives the driving pulley 2352 to rotate, and the driving pulley 2352 is connected to the driven pulley 2353 through the synchronous belt 2354, thereby driving the winding wheel 233 to rotate.

[0054] In one embodiment, please refer to Figures 1-5, two adjacent ones of the support rods 311 are hinged via a first pin shaft 312, a first torsion spring 313 is sleeved on the first pin shaft 312, and two ends of the first torsion spring 313 are respectively connected to the corresponding two support rods 311. The folding rod 31 further includes a first fixing block 314 and a second fixing block 315. The first fixing block 314 is fixed to the partition plate 21. The support rod 311 closest to the partition plate 21 is hinged to the first fixing block 314 via a second pin shaft 316. A second torsion spring 317 is sleeved on the second pin shaft 316, and two ends of the second torsion spring 317 are respectively connected to the corresponding support rod 311 and the first fixing block 314. The second fixing block 315 is fixed to the inner top surface of the water tank 1. The support rod 311 closest to the inner top surface of the water tank 1 is hinged to the second fixing block 315 via a third pin shaft 318. A third torsion spring 319 is sleeved on the third pin shaft 318, and two ends of the third torsion spring 319 are respectively connected to the corresponding support rod 311 and the second fixing block 315. The specifications of the first torsion springs 313, the second torsion springs 317 and the third torsion springs 319 are the same. Since the specifications of the first torsion springs 313, the second torsion springs 317 and the third torsion springs 319 are the same, the included angles between two adjacent support rods 311 are ensured to be equal. This enables the water quality detection member 32 to be evenly distributed in the water tank 1 when the folding rod 31 is unfolded, thereby achieving more comprehensive and uniform disinfection of the water body in the water tank 1, avoiding the occurrence of disinfection dead corners, and improving the uniformity and effectiveness of disinfection.

[0055] In one embodiment, please refer to Figure 1 and Figure 2 , the cleaning mechanism 4 further includes a first connecting pipe 43, a three-way valve 44, a second connecting pipe 45, a first stop valve 46 and a second stop valve 47. One end of the first connecting pipe 43 is communicated with the outlet of the cleaning pump 41. The first interface of the three-way valve 44 is communicated with the other end of the first connecting pipe 43. The second interface of the three-way valve 44 is communicated with the sewage discharge pipe 42. The third interface of the three-way valve 44 is communicated with one end of the second connecting pipe 45. The other end of the second connecting pipe 45 is communicated with the cleaning inlet 14. The first stop valve 46 is arranged on the sewage discharge pipe 42. The second stop valve 47 is arranged on the second connecting pipe 45.

[0056] In this embodiment, when the partition plate 21 descends and divides the water tank 1 into upper and lower parts, the cleaning pump 41 is started. At this time, the second stop valve 47 is in the open state, and the first stop valve 46 is in the closed state. The water at the bottom of the water tank 1 is sucked into the cleaning pump 41 from the cleaning outlet 13, reaches the three-way valve 44 through the first connecting pipe 43. Since the first stop valve 46 is closed, the water flow can only enter the second connecting pipe 45 through the third interface of the three-way valve 44, and then re-flow into the bottom of the water tank 1 from the cleaning inlet 14, thereby realizing the circulating flow of the water at the bottom of the water tank 1, flushing and cleaning the bottom of the water tank 1, and separating the impurities attached to the inner wall of the water tank 1. After a period of circulating cleaning, it is necessary to discharge the sewage containing impurities. At this time, the second stop valve 47 is closed, and the first stop valve 46 is opened. The water flow coming out of the cleaning pump 41 reaches the three-way valve 44 through the first connecting pipe 43. Since the second stop valve 47 is closed, the water flow can only flow into the sewage pipe 42 through the second interface of the three-way valve 44, and finally discharge the sewage from the water tank 1. After the sewage is discharged, the first stop valve 46 is closed, and the second stop valve 47 is opened again to make the bottom of the water tank 1 enter the circulating cleaning state again. Repeat the steps of circulating cleaning and sewage discharge to perform the cleaning operation a preset number of times.

[0057] In this embodiment, through the settings of the first stop valve 46 and the second stop valve 47, the water flow direction can be flexibly controlled to realize the two different functions of circulating cleaning of the water at the bottom of the water tank 1 and sewage discharge. During circulating cleaning, ensure that the water flow circulates at the bottom of the water tank 1 to effectively wash away impurities; when discharging sewage, guide the water flow to directly enter the sewage pipe 42 for discharge, avoiding the sewage from entering the inside of the water tank 1 again, and ensuring the high efficiency and orderliness of the cleaning process.

[0058] In one of the embodiments, please refer to Figure 1 and Figure 2 , the secondary water supply pollution-free automatic sampling and testing device further includes a sludge scraping mechanism 5. The sludge scraping mechanism 5 includes a lead screw 51, a second rotation driving motor 52, a nut 53, a guide rod, a sliding sleeve, a sleeve 54, a shaft rod 55, an elastic member 56 and a scraping blade 57. The lead screw 51 is rotatably arranged in the water tank 1. The second rotation driving motor 52 is connected to the lead screw 51 and is used to drive the lead screw 51 to rotate. The nut 53 is threadedly rotatably connected to the lead screw 51. The guide rod is fixed in the water tank 1 and is parallel to the lead screw 51. The sliding sleeve is slidably sleeved on the guide rod. The sliding sleeve is fixedly connected to the nut 53. The sleeve 54 is fixed to the nut 53. The shaft rod 55 is slidably inserted into the sleeve 54. The elastic member 56 is located in the sleeve 54. One end of it is fixed to the sleeve 54, and the other end is fixed to one end of the shaft rod 55. The other end of the shaft rod 55 is connected to the scraping blade �7, and the scraping blade 57 abuts against the inner bottom surface of the water tank 1.

[0059] In this embodiment, when the water tank cleaning mechanism 4 cleans the bottom of the water tank 1, the sludge scraping mechanism 5 works synchronously. The second rotation driving motor 52 is started to drive the lead screw 51 to rotate in the water tank 1. Since the nut 53 is in threaded rotation connection with the lead screw 51, the nut 53 will move along the axial direction of the lead screw 51. During the movement of the nut 53, the sliding sleeve fixedly connected thereto slides on the guide rod. The guide rod is arranged parallel to the lead screw 51 to play a guiding role and ensure that the nut 53 and the sliding sleeve move smoothly along a straight line. At the same time, the sleeve 54 fixed on the nut 53 also moves accordingly. Adaptive adjustment and sludge scraping of the scraping blade: When the sleeve 54 moves, the shaft rod 55 can slide in the sleeve 54, and the elastic member 56 is located in the sleeve 54, and its two ends are respectively fixed on the sleeve 54 and the shaft rod 55. When the scraping blade 57 encounters an uneven inner bottom surface of the water tank 1 or a large resistance, the shaft rod 55 can slide in the sleeve 54 and compress the elastic member 56, so that the scraping blade 57 always keeps in contact with the inner bottom surface of the water tank 1 to ensure the sludge scraping effect. During the process of the nut 53 driving the sleeve 54 to move, the scraping blade 57 moves accordingly to scrape off impurities such as sediment attached to the inner bottom surface of the water tank 1, and cooperate with the water flow scouring of the cleaning mechanism 4 to make the impurities easier to be carried away.

[0060] In this embodiment, the setting of the sludge scraping mechanism 5 forms a synergistic effect with the water flow scouring of the cleaning mechanism 4 through the direct scraping action of the scraping blade 57 on the inner bottom surface of the water tank 1. The scraping blade 57 can scrape up impurities such as sediment that are more firmly attached, making these impurities easier to be carried away by the water flow, so as to more thoroughly clean the bottom of the water tank 1, further reduce the residue of impurities in the "dead water area", significantly improve the cleaning degree of the bottom of the water tank 1, and ensure the water quality safety of secondary water supply.

[0061] In one of the embodiments, please refer to Figure 1 and Figure 2 , a positioning ring 17 is formed on the inner side wall of the water tank 1, and the partition plate 21 is used to abut against the positioning ring 17. In this embodiment, the setting of the positioning ring 17 on the inner side wall of the water tank 1 provides a clear positioning mark for the partition plate 21 to form a space for the cleaning mechanism 4 to achieve normal cleaning. When the partition plate 21 descends driven by the lifting driving member 23, it can accurately abut against the positioning ring 17 to ensure that the partition plate 21 can reach a fixed and appropriate position each time, accurately divide the water tank 1 into upper and lower parts, and ensure that subsequent operations such as cleaning and disinfecting the bottom water body are carried out in a stable space environment. In addition, since the partition plate 21 is made of a high-strength and high-density material (such as stainless steel), there is a large pressure between the partition plate 21 and the positioning ring 17, so that the partition plate 21 and the positioning ring 17 can be closely attached, thereby ensuring the effective isolation between the detection cavity and the cleaning cavity. In a preferred embodiment, a sealing ring can also be provided on the lower end surface of the partition plate 21 or the upper end surface of the positioning ring 17 to further improve the isolation effect between the detection cavity and the cleaning cavity.

[0062] The specific implementation manners of the present application described above do not constitute a limitation on the protection scope of the present application. Any other corresponding changes and deformations made according to the technical concept of the present application shall be included within the protection scope of the present application.
