Description

Technical Field

[0001] The invention relates to the field of water meters, in particular to a water meter with a water mist cleaning function. Background Art

[0002] A water meter is an instrument used to measure water flow. It is one of the indispensable devices in households and industries. It is usually installed on tap water pipes. The water flow drives the impeller inside the meter to rotate, thereby calculating the water flow.

[0003] There is a certain space inside the water surface. When the outdoor temperature is low and the water temperature in the water meter is high, condensation will form water mist on the surface or inside of the water surface, making it difficult to observe the information on the dial. The existing Chinese public patent document: CN118706212A discloses a 24V power supply water meter with a water mist removal function. When water flows into the diversion cabin through the liquid inlet joint, the water in the diversion cabin drives the impeller to operate through the inclined liquid inlet at the bottom of the diversion member. The impeller drives the first driven tooth on the first rotating shaft through the first transmission tooth, and the first rotating shaft drives the second driven tooth of the second rotating shaft through the second transmission tooth, so that the first scraper scrapes the water mist on the first lens, thereby achieving the effect of automatically removing the water mist on the first lens, without the operator manually wiping, which brings convenience to the operator. Although the water mist on the surface of the water meter can be removed, the temperature difference outdoors will cause the inside of the water meter to condense into water mist, and the scraper is difficult to clean the water mist inside the water meter, which will still affect the normal reading of the water meter.

[0034] When the swivel 10 rotates, the water inlet cylinder 16 can be driven to move synchronously through the mounting tube 9. The water inlet cylinder 16 and the U-shaped frame 8 drive the bevel gear 20 on the mounting rod 17 to move along the teeth of the conical gear ring 21, so that the bevel gear 20 drives the mounting rod 17 to rotate, and the mounting rod 17 drives the spiral bar 18 to rotate along the inner side of the U-shaped frame 8 and the mounting tube 9, so that the water in the U-shaped frame 8 is discharged from the mounting tube 9 into the water inlet cylinder 16 and discharged from the drain pipe 19, so as to prevent excessive water accumulation in the U-shaped frame 8 and ensure the normal mist removal of the arc scraper 7, thereby achieving the effect of rapid drainage.

[0035] Working principle: First, the staff aligns the two ends of the water inlet bin 1 with the pipeline. The water entering the water inlet bin 1 can drive the impeller shaft 11 to rotate, so that the dial 4 monitors the water flow in the water inlet bin 1 through the rotation of the impeller shaft 11. At the same time, the impeller shaft 11 drives the two driven rods 12 to rotate synchronously through the synchronous belt 13, so that the driven rods 12 drive the transmission gear 14 to rotate, and the transmission gear 14 drives the transmission gear ring 15 at the bottom of the rotating ring 10 to rotate, so that the transmission gear ring 15 drives the rotating ring 10 synchronously. The rotating ring 10 drives the annular slide bar 29 to rotate along the inner side of the annular slide rail 30, so that the rotating ring 10 drives the U-shaped frame 8 to make a circular motion smoothly through the mounting tube 9, and the U-shaped frame 8 drives the arc scraper 7 to make a circular motion along the inner side of the glass plate 3 to scrape off the water mist on the inner side of the glass plate 3, and the water mist on the arc scraper 7 gathers into water drops and slides into the inner side of the U-shaped frame 8 along the guide strip 32. At the same time, the mounting tube 9 drives the water inlet cylinder 16 to move synchronously, so that the water inlet cylinder 16 and the U-shaped frame 8 are brought The movable mounting rod 17 makes a circular motion with the center of the swivel 10, and the bevel gear 20 driven by the mounting rod 17 moves along the teeth of the conical gear ring 21. The bevel gear 20 can be in a rotating state when moving. As a result, the bevel gear 20 drives the mounting rod 17 to rotate, and the mounting rod 17 drives the spiral bar 18 to rotate synchronously, so that the spiral bar 18 sends the water in the U-shaped frame 8 into the mounting pipe 9, and then sends the water in the mounting pipe 9 into the water inlet cylinder 16. The water in the water inlet cylinder 16 is discharged downward from the drain pipe 19 to prevent the U-shaped frame 8 from accumulating too much water. The arc scraper 7 can continuously scrape off the water mist on the inner side of the glass plate 3 to ensure the normal meter reading of the staff. Finally, after the sealing cover plate 6 is closed, the rubber ring 28 on the sealing cover plate 6 can be inserted into the annular groove on the top of the case 2, so as to improve the sealing performance of the sealing cover plate 6 to the top of the case 2 and prevent dust from adhering to the glass plate 3, thereby achieving the effect of automatic demisting and dustproof, which is convenient for the staff to read the meter at any time and improves the convenience of using the water meter.

[0036] Example 2: Please refer to Figure 2-Figure 8The present embodiment further illustrates the first embodiment.

The top of the water storage tank 22 is provided with an annular opening for the limited sliding of the water supply and drainage pipe 19, so that the rotating ring 10 can drive the drainage pipe 19 to move along the annular opening on the water storage tank 22. The top of the water storage tank 22 is fixedly mounted with an outer frame 23 and an inner frame 24. The inner frame 24 is located on the inner side of the outer frame 23. The outer frame 23 and the inner frame 24 are all annular structures, the center of the outer frame 23 and the inner frame 24 are the same, the drain pipe 19 is located between the outer frame 23 and the inner frame 24, and a sealing ring 25 is slidably installed between the outer frame 23 and the inner frame 24.

A drain pipe 26 is fixedly installed at the bottom of the water storage tank 22. The drain pipe 26 extends to the outside of the watch case 2 and can discharge the water in the water storage tank 22. A sealing plug 27 is installed at the end of the drain pipe 26 away from the water storage tank 22.

[0037] In the present embodiment: the drain pipe 19 can discharge the water in the water inlet cylinder 16 into the water storage tank 22, and when the swivel 10 rotates, the swivel 10 drives the water inlet cylinder 16 to move synchronously through the mounting tube 9, so that the water inlet cylinder 16 can drive the sealing ring 25 to move along the outer frame 23 and the inner frame 24 through the drain pipe 19, and the sealing ring 25 keeps the annular opening at the top of the water storage tank 22 sealed, and when inspecting the water meter, the staff can open the sealing plug 27 on the drain pipe 26 to discharge the water in the water storage tank 22 to the outside, thereby achieving the effect of sealed water storage and facilitating centralized discharge.

[0039] In this embodiment: the sleeves 31 on both sides of the dial 4 can provide support for the driven rod 12, ensuring that the driven rod 12 can stably drive the transmission gear ring 15 to rotate through the transmission gear 14, and when the rotating ring 10 rotates, it can drive the sealing ring 25 to move along the inner side of the outer frame 23 and the inner frame 24 through multiple support rods 34, so that the drain pipe 19 can discharge the water in the water inlet cylinder 16 into the water storage tank 22. The sealing ring 25 can drive the ball 35 to move along the slide groove of the outer frame 23 and the inner frame 24, thereby improving the stability of the sealing ring 25 during rotation.

[0040] In some embodiments, a processor (not shown in the figure) and a micro camera (not shown in the figure) are also included. The micro camera is facing the dial 4. The processor is connected to the micro camera signal. The micro camera sends the video of the dial 4 to the processor. The processor has a built-in trained gated cycle unit.
