[0034] Going further;

[0035] In an optional embodiment, a protective cover 505 is fixedly mounted on the upper surface of the outer condensation cover 3 by means of bolts.

[0036] In this embodiment, the protective cover 505 can protect the driving motor 501 and extend the service life of the driving motor 501 .

[0037] Further,

[0038] In an optional embodiment, a cleaning assembly 6 is installed on the connecting pipe 509, and the cleaning assembly 6 includes a telescopic rod 609 fixed between the sleeve 510 and the filter screen 511 and arranged symmetrically, a spring 608 wound on the surface of the telescopic rod 609, and a sewage pipe 604 connected and fixed on the surface of the connecting pipe 509, a control valve 2 605 is installed inside the sewage pipe 604, a control valve 1 603 is installed inside the connecting pipe 509, a water storage tank 606 is fixedly installed on the lower surface of the water consumption measuring mechanism 41, and the water storage tank 606 is fixedly connected to the cooling tower body 1, and the surface of the return water loop 4 is close to the connecting pipe 509. A water pump 601 is fixedly installed on one side through a support plate, a water pumping pipe 602 is fixed to the input end of the water pump 601, the other end of the water pumping pipe 602 is fixedly connected to the water tank 606 and communicated with the water tank 606, a drain pipe 607 is fixed to the output end of the water pump 601, one end of the drain pipe 607 penetrates into the interior of the connecting pipe 509, and the discharge end of the drain pipe 607 corresponds to the filter screen 511, an installation groove is provided on the side of the lower surface of the sleeve 510 close to the spring 608, the spring 608 and the telescopic rod 609 are both located in the installation groove, and the drainage end of the water consumption measuring mechanism 41 is communicated with the water tank 606.

[0039] In this embodiment: after a single measurement, the control system in the prior art controls the drainage solenoid valve on the water consumption measurement mechanism 41 to open once, and the water inside the cylinder is discharged to the inside of the water storage tank 606 to collect the water. As the filter 511 continuously filters the water, when it is necessary to clean the impurities on the surface of the filter 511, the control valve 2 605 is opened and the control valve 1 603 is closed at the same time. At this time, the water pump 601 is started, and then the water inside the water storage tank 606 is pumped out through the pumping pipe 602 and discharged into the drain pipe 607, and discharged through the drain pipe 607. The water flow discharged from the drain pipe 607 impacts the filter 511. At this time, the filter 511 moves downward and stretches the spring 608 and the telescopic rod 609. At this time, there will be a certain gap between the filter 511 and the sleeve 510. At this time, the filter 51 The sewage impacted by 1 is discharged along the gap between the filter screen 511 and the sleeve 510, and is discharged through the gap between the filter screen 511 and the connecting pipe 509.

[0040] It should be noted that the maximum diameter of the bottom of the filter screen 511 is smaller than the inner diameter of the connecting pipe 509 , and larger than the inner diameter of the sleeve 510 .

[0041] Going further;

[0044] Working principle and use process of the utility model: when the water consumption measuring device of the water-saving cooling tower of the thermal power plant is in use, before the water consumption measuring mechanism 41 measures the water level, the driving motor 501 is started to drive the worm 502 to rotate, and the worm 502 is meshed and connected with the turbine 503, thereby driving the turbine 503 to rotate, and the rotating column 504 is driven to rotate by the turbine 503, and the strip scraper 506, the semicircular scraper 507 and the drainage cover 508 are driven to rotate synchronously by the rotating column 504, and the water droplets remaining on the inner wall of the inner condensation cover 2 are hung up by the strip scraper 506 and dropped into the inner part of the return water loop 4, and the strip scraper 506 can better drain the water to the return water through the drainage cover 508 while scraping off the water droplets. Inside the water annular channel 4, the water inside the water return annular channel 4 is continuously scraped by the semicircular scraper 507. When the semicircular scraper 507 moves to the position of the connecting pipe 509, when the water passes through the connecting pipe 509, the impurities in the water can be filtered through the sleeve 510 and the filter screen 511. At this time, the filtered water is discharged to the inside of the water consumption measuring mechanism 41 along the connecting pipe 509, and the water level is measured by the water consumption measuring mechanism 41. Through this operation, the water droplets remaining on the inner wall of the inner condensation cover 2 and the water return annular channel 4 can be completely drained to the inside of the water consumption measuring mechanism 41 through the connecting pipe 509, and the impurities in the water are filtered at the same time, so that the collected water is not affected by the impurities, and the water level inside the measuring cylinder on the water consumption measuring mechanism 41 is ensured to be accurate.

After a single measurement, the control system in the prior art controls the drainage solenoid valve on the water consumption measurement mechanism 41 to open once, and the water inside the cylinder is discharged to the inside of the water storage tank 606 to collect the water. As the filter 511 continuously filters the water, when it is necessary to clean the impurities on the surface of the filter 511, the control valve 2 605 is opened and the control valve 1 603 is closed at the same time. At this time, the water pump 601 is started, and then the water inside the water storage tank 606 is pumped out through the pumping pipe 602, and discharged into the drain pipe 607, and discharged through the drain pipe 607. The water flow discharged from the drain pipe 607 impacts the filter 511, and the filter 511 moves downward at this time, and the spring 606 is pressed against the filter 511. 08 and the telescopic rod 609 are stretched, and at this time, a certain gap will be generated between the filter screen 511 and the sleeve 510. At this time, the sewage impacted by the filter screen 511 is discharged along the gap between the filter screen 511 and the sleeve 510, and at the same time, it is discharged through the gap between the filter screen 511 and the connecting pipe 509. At this time, the sewage in the connecting pipe 509 is discharged through the sewage pipe 604, and the filter screen 511 is continuously flushed, so as to complete the cleaning operation of the filter screen 511. Through regular cleaning, it is possible to effectively avoid clogging of the filter screen 511 and affect the flow effect of water. By eliminating the need for manual cleaning, the labor intensity of the staff is reduced, and the use effect of the device is further improved. Through the setting of the partition 610, the water discharged from the drain pipe 607,When the filter 511 is cleaned, the water pump 601 is turned off. At this time, the spring 608 rebounds and shrinks to reset, and drives the filter 511 to fit the bottom of the sleeve 510. At the same time, the control valve 1 603 is opened, and the control valve 2 605 is closed, and the water level measurement of the water consumption measurement mechanism 41 is continued.
