Description

[0002] With the continuous development of the industrial economy and urban scale, water meters, as instruments for measuring water flow, are becoming increasingly widely installed and used in industry and in daily life. Water meters on the market primarily measure water consumption by rotating the impeller blades driven by water flow, which in turn drives the gears on the counter.

[0003] At present, some water meters are in use. First, if the faucet is in the dripping stage, the water meter will not detect it at this time, which is simply called the water meter not moving. The principle of the water meter is to use the water flow through the runner to drive the runner to rotate, and the rotation of the runner will drive the mechanical rotating gear set inside the water meter to rotate. If the faucet is in the dripping stage, the flow rate inside the water meter will be basically negligible. At this time, the water meter will not move, so monitoring cannot be achieved. Therefore, in real life, some water meters will not move during the dripping stage of the faucet, resulting in the water supply bureau's water meter detection lacking accurate values.

[0028] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0029] See also Figure 1-Figure 7 A smart water meter capable of monitoring drip flow comprises a shell 1, with a water inlet pipe 3 and a water outlet pipe 4 connected to the left and right ends of the shell 1 respectively, a display cover 2 mounted on the shell 1, a numerical component 5 disposed inside the display cover 2, and a sensitive monitoring component 6 disposed inside the shell 1; the sensitive monitoring component 6 comprises a rotating device and a compression device.

[0030] In this embodiment, the rotating device includes a central shaft 61, which is rotatably connected to the interior of the housing 1. A plurality of blades 65 are connected to the central shaft 61. A spacer 66 is fixedly connected to the interior of the housing 1, and a section of the plurality of blades 65 abuts against the spacer 66. The compression device includes a stopper 64, which is slidably connected to the surface of the plurality of blades 65. A turntable 68 is connected to the top of the stopper 64, which is rotatably connected to the interior of the housing 1. A plurality of plugs 62 are fixedly connected to the stopper 64, and a compression spring 63 is sleeved on the plugs 62. The compression spring 63 is located between the turntable 68 and the stopper 64. A key 67 is provided in the turntable 68, and the key 67 is connected to the numerical component 5. When the faucet is in a dripping state, that is, a state of very slow flow rate, at this time, due to the downward pressure of the elastic force of the extrusion spring 63, the baffle 64 will be driven to slide downward as a whole. At this time, the edge of the baffle 64 will block the upper half of the filter 702. At this time, as the baffle 64 slides down, the contact area of ​​the blade 65 with the water flow will decrease, that is, the height will decrease, and the water flow will flow through the space between the baffle 64 and the shell 1. The smaller the space, the greater the sensitivity of the water flow, which is similar to reducing the flow space of the water flow. After the space is reduced, even if the water flow is very little, it will be very obvious, and the smaller the space, the more obvious it will be to push the blade 65 to rotate.

[0031] Furthermore, by setting up a sensitive monitoring component 6, it can automatically reduce the flow space of the water when the faucet is dripping, that is, when the water flow inside the water meter is small. After the flow space is reduced, when there is less aqueous solution flowing at the outlet end, it can still drive the rotation of the blade 65, and then drive the operation of the numerical component 5. Therefore, the overall method of compressing the water flow space is used to realize low-flow monitoring of the water flow, thereby ensuring the flow accuracy of the water meter.

[0032] The numerical assembly 5 also includes a mounting cover 52, which is mounted on the display cover 2. A gearbox 51 is mounted within the display cover 2. Gearbox 51 houses a gear train 55, which is connected to multiple numerical dials 53. A digital display wheel 54 is also mounted on the gearbox 51. A display wheel 56 is rotatably connected to the gearbox 51. A key 57 is connected to the bottom of the display wheel 56 via a shaft. This key 57 has a slot in which a key 67 engages. Rotating a dial 68 connected to the blade 65 via a post 62 rotates, driving the key 67. This, in turn, drives the key 67. This rotation of the key 57, through the shaft connection, causes the gearbox 55 within the gearbox 51 to rotate accordingly, driving the display wheel 56 and the multiple numerical dials 53. The operator can directly monitor the flow status within the meter by observing the rotation of the dials.

[0033] In addition, the invention also includes a filter assembly 7, which includes a filter screen 702, which is fixed on the spacer 66. A tension spring 701 is installed inside the spacer 66. One end of the tension spring 701 is fixedly connected to the spacer 66. The other end of the tension spring 701 is equipped with a cleaning rack for cleaning the filter screen 702 in real time. The tension spring 701 provided can continuously stretch a cleaning rod 7041 to slide on the filter screen 702, thereby achieving reciprocating motion cleaning. The cleaning rack includes a connecting piece 704 and a cleaning rod 7041. One end of the tension spring 701 is connected to the cleaning rod 7041 through the connecting piece 704, and the cleaning rod 7041 abuts against the surface of the filter screen 702. The connecting member 704 includes a slide plate 7044, and the surface of the slide plate 7044 is slidably connected to the connecting support rod 7042. The two ends of the connecting support rod 7042 are connected to the cleaning rod 7041. The connecting support rod 7042 is provided with a sliding groove 7043. The slide plate 7044 is located inside the sliding groove 7043. One side of the slide plate 7044 is connected to the tension spring 701. A straight groove 703 is provided on the filter screen 702. The connecting support rod 7042 is slidably connected to the inside of the straight groove 703. A clearance groove 707 is provided on the filter screen 702. Because when the blade 65 rotates, it cannot drive the cleaning rod 7041 to rotate all the time, but cleans the local position of the filter 702, so a horizontal yielding moving device is set. During the rotation of the blade 65, it will also contact the cleaning rod 7041 on the inner side of the filter 702, thereby driving the cleaning rod 7041 and the connecting support rod 7042 to slide along the straight groove 703, thereby scraping impurities from the filter 702. When it rotates to the position of the yielding groove 707, the blade 65 will push the cleaning rod 7041 into the inside of the yielding groove 707. At this time, the blade 65 will Continue to rotate normally in the spacer 66, and at this time, after the cleaning rod 7041 enters the inside of the give way groove 707 horizontally, the connecting support rod 7042 and the slide plate 7044 will slide in the sliding groove 7043. The faster the blade 65 rotates, the faster the water flow rate, so the blade 65 will always "hit" the cleaning rod 7041, restricting it to the inside of the give way groove 707. If the rotation speed is too slow, the tension of the tension spring 701 will pull the cleaning rod 7041 at both ends of the connecting support rod 7042 to reset, thereby cleaning the impurities on the filter screen 702.

[0034] It is worth noting that a collection box 705 is provided below the filter 702 and is inserted into the interior of the housing 1. A nut 706 is rotatably connected to one side of the collection box 705 via a shaft, and the nut 706 is threadedly connected to the housing 1. After cleaning and depositing impurities on the filter 702, they will fall into the collection box 705. If cleaning is required, the valve of the pipeline is closed, and then the nut 706 is rotated to separate it from the housing 1. The entire collection box 705 is then pulled out, the impurities inside are poured out, and then it is reinstalled into the interior of the housing 1.

[0035] When water flows into the shell 1 from the water inlet pipe 3, it will directly enter the interior of the shell 1 from the position of the filter 702, and then use the flow of water to drive the rotation of the blade 65, and the blade 65 will drive the rotation of the central shaft 61, and the turntable 68 connected to the blade 65 through the plug column 62 will rotate, and then drive the plug key 67 to rotate, and the plug key 67 will drive the card key 57 to rotate. Through the connection of the shaft, the gear set 55 inside the gear box 51 will rotate accordingly, and then drive the display wheel 56 to rotate, and also drive multiple numerical meters 53 to rotate. The operator can directly check the flow status in the water meter at this time according to the rotation of the meter. When the faucet is in a dripping state, that is, the flow rate is very slow, at this time, due to the downward pressure of the elastic force of the extrusion spring 63, the baffle 64 will be driven to slide downward as a whole. At this time, the edge of the baffle 64 will block the upper half of the filter 702. At this time, as the baffle 64 slides down, the contact area of ​​the blade 65 with the water flow will decrease, that is, the height will decrease, and the water will flow through the space between the baffle 64 and the shell 1. The smaller the space, the more sensitive the water flow will be, which is similar to reducing the flow space of the water flow. After it becomes smaller, even if the water flow is slightly missing, it will be very obvious, and the smaller the space, the more it can push the blade 65 to rotate. When the faucet is in the normal water discharge state, the flow force of the water inlet pipe 3 will increase, so the flowing water will lift a portion of the retaining sleeve 64, increasing the flow space of the water. At the same time, because the retaining sleeve 64 is in the water flow, even in the water discharge stage, the entire device is immersed in water, and there is no pressure increase or pressure reduction. Even if there is a certain water pressure change, the retaining sleeve 604 is relatively in the water flow, in a vacuum stage. This technical solution uses the momentum of the water flow to drive the retaining sleeve 604 upward. When the water flow rate is too slow, it will be pressed down by the elastic force of the spring, compressing the flow space of the water flow, realizing highly sensitive water flow monitoring.During the rotation of the blade 65, it will also contact the cleaning rod 7041 inside the filter screen 702, thereby driving the cleaning rod 7041 and the connecting support rod 7042 to slide along the straight groove 703, thereby scraping impurities from the filter screen 702. When it rotates to the position of the give way groove 707, the blade 65 will push the cleaning rod 7041 into the inside of the give way groove 707. At this time, the blade 65 will continue to rotate normally in the spacer 66. At this time, after the cleaning rod 7041 enters the inside of the give way groove 707 horizontally, the connecting support rod 7042 and the slide plate 7044 will slide in the sliding groove 7043. As the blade 65 rotates further The faster the speed, the faster the water flows, so the blade 65 will always "hit" the cleaning rod 7041, limiting it to the inside of the give way slot 707. If the speed is too slow, the tension of the tension spring 701 will pull the cleaning rod 7041 connecting the two ends of the support rod 7042 to reset, thereby cleaning the impurities on the filter 702. The cleaned impurities will be deposited inside the collection box 705. If cleaning is needed later, it is necessary to close the valve of the pipeline, then turn the nut 706 to separate it from the shell 1, then pull out the entire collection box 705, pour out the impurities inside, and then install it into the inside of the shell 1.
