Description

Technical Field

[0001] The utility model relates to the technical field of intelligent water meters, in particular to an intelligent water meter with a pressure-boosting function. Background Art

[0002] Smart water meter is a new type of water meter that uses modern microelectronics technology, modern sensor technology, and smart IC card technology to measure water consumption and transmit water consumption data and settle transactions. Compared with traditional water meters that generally only have the functions of flow collection and mechanical pointer display of water consumption, smart water meters can not only record and electronically display water consumption, but also control water consumption according to demand. However, due to the different tap water supply systems in various places, and the high-rise or remote areas, the pressure of tap water is severely weakened, so that the water pressure cannot meet people's normal water needs;

[0003] In response to the above problems, the Chinese publication number: CN208536948U "A smart water meter with a boosting function" sets a pressure sensor at the water inlet inside the smart water meter body to detect the water pressure. When the water pressure is insufficient, the pressure sensor sends an electrical signal to the single-chip microcomputer to control the boosting pump to work, so as to achieve the purpose of boosting.

[0004] However, this type of smart water meter still has certain defects when in use. For example, this type of smart water meter installs the pressure sensor detection at the water inlet inside the smart water meter body. The pressure sensor is in contact with water for a long time. After long-term use, it is easily affected by impurities in the water, which will cause scaling on the sensor surface and aging of the sensor element, affecting its detection effect, and indirectly affecting the normal operation of the booster pump linked to it. In addition, after long-term use of this type of smart water pipe, impurities such as mud or algae will accumulate in the water pipe. These impurities enter the booster pump under the drive of the water flow, which will affect the service life of the booster pump. Utility Model Content

This smart water meter with a pressurization function can realize the pressurization of water in the pipeline through the setting of a pressurization component, and at the same time, it is convenient for the staff to repair or replace the pressure sensor, and through the setting of a filter component, it can filter impurities such as silt or algae in the pipeline, and at the same time, it can replace and clean the filter during the normal water supply of the pipeline. The smart water meter with a pressurization function is described in detail below. It should be noted that the description order of the following embodiments is not intended to limit the preferred order of the embodiments.

[0028] The present application is described in detail below with reference to the accompanying drawings and specific implementation methods. Example 1

[0029] See also Figure 1-7 In this embodiment, a smart water meter with a pressurization function is provided, comprising:

[0030] A smart water meter body 1, a booster pump 4 is provided on one side of the smart water meter body 1, a box body 2 is provided on one side of the smart water meter body 1, a filter block 3 is provided on one side of the box body 2, a filter cavity a301 is provided inside the filter block 3, a filter cavity b302 is provided inside the filter block 3, and filter nets 701 are provided inside the filter cavity a301 and the filter cavity b302; a booster component provided between the box body 2 and the booster pump 4 is used for pressurizing the pipeline; and a filter component provided inside the filter block 3 is used for filtering impurities inside the pipeline and facilitating the replacement and cleaning of the filter net 701.

[0031] Among them, by setting the boosting component, the water in the pipeline can be pressurized, and by setting the cover 604 and the connecting pipe 603, it is convenient for the staff to repair or replace the pressure sensor 605, so as to avoid the abnormal operation of the boosting pump 4 caused by the failure of the pressure sensor 605;

[0032] Secondly, through the setting of the filtering component, impurities such as mud or algae in the pipeline can be filtered. At the same time, through the setting of the fixed rod 8, the blocking piston a801, the blocking piston b802 and the electric telescopic rod 9, the filter net 701 can be replaced and cleaned during the normal water flow of the pipeline without stopping the water delivery, thereby improving the efficiency of replacing and cleaning the filter net 701. Example 2

[0033] On the basis of Example 1, the boosting component includes: a guide tube b102 connected to one side of the smart water meter body 1, one end of the guide tube b102 is fixedly connected to the box body 2, one side of the smart water meter body 1 is connected to a guide tube a101, one side of the guide tube a101 is connected to a boosting water pipe 401, and the top of the boosting pump 4 is connected to the boosting water pipe 401; a water cavity 204 is opened inside the box body 2, a piston a5 is arranged inside the water cavity 204, an extrusion cavity 206 is opened inside the box body 2, a connecting rod b505 is fixedly connected to the top of the piston a5, and the top end of the connecting rod b505 extends into the extrusion cavity 206. It is fixedly connected with a piston b504, a compression chamber 205 is opened inside the box body 2, a connecting rod a501 is provided at the bottom of the piston a5, the bottom end of the connecting rod a501 extends into the compression chamber 205, and is fixedly connected with an extrusion plate 502, and a spring 503 is provided at the bottom of the extrusion plate 502; a connecting pipe 603 is arranged on one side of the box body 2, an extrusion piston 6 is arranged inside the extrusion chamber 206, an extrusion rod 601 is fixedly connected to one side of the extrusion piston 6, and one end of the extrusion rod 601 extends into the connecting pipe 603, a sealing cover 604 is provided at one end of the connecting pipe 603, and a pressure sensor 605 is provided inside the sealing cover 604.

[0034] Among them, one end of the connecting tube 603 is provided with an external thread, and the inside of the cover 604 is provided with an internal thread matching the external thread at one end of the connecting tube 603; the outside of the extrusion rod 601 is sleeved with a compression spring 602, and the compression spring 602 is located inside the extrusion cavity 206.

[0035] When in use, the smart water meter is installed on the water pipeline. When the water pressure inside the pipeline is normal, water passes through the filter block 3 and the drainage tube 203 and enters the water chamber 204. Then, under the water pressure, the piston a5 will keep squeezing the spring 503 through the connecting rod a501 and the squeezing plate 502. At this time, the booster pump 4 remains in the off state. When the water pressure in the water pipeline is insufficient, the spring 503 is released, thereby applying an upward force to the squeezing plate 502 and the piston a5, so that the piston a5 and the connecting rod b505 drive the piston b504 to move upward, thereby squeezing the water in the squeezing chamber 206, and then the squeezing piston 6 and the squeezing rod 601 are pushed by the water in the squeezing chamber 206 to move in the direction close to the pressure sensor 605, thereby triggering the pressure sensor 605. The pressure sensor 605 generates an electrical signal and sends it to the control terminal, and the booster pump 4 is started through the control terminal.

[0036] In addition, by providing the compression spring 602 , the squeezing piston 6 and the squeezing rod 601 can be reset when the water pressure in the water pipeline is normal.

[0037] When the pressure sensor 605 needs to be repaired or replaced, the staff can twist the cover 604 to separate the cover 604 from the connecting pipe 603, and then the pressure sensor 605 can be taken out for repair or replacement.

[0038] In addition, the pressure sensor 605 is a piezoelectric pressure sensor, and the model may be PT124G-213. When external pressure acts on the sensor, the piezoelectric element inside the pressure sensor 605 is deformed, and thus generates corresponding charges. These charges are detected and amplified through appropriate electronic circuits, and finally a voltage or current signal output proportional to the input pressure is obtained, thereby starting the boost pump 4 and making the boost pump 4 work. The pressure sensor 605 is a mature conventional technology in this technical field, and this scheme does not make improvements to the circuit or program of the pressure sensor 605, so the circuit and signal connection relationship of the pressure sensor 605 will not be elaborated.

[0040] Among them, a diverter pipe a201 is connected to one side of the filter block 3, and a diverter pipe b202 is connected to one side of the filter block 3.

[0041] When water enters the diversion chamber 305 through the water supply pipe and flows into the filter chamber a301 through the diversion groove b307 and the water inlet a308, the filter net 701 will filter the mud and sand in the water supply pipe, and then flow into the box body 2 through the diversion pipe b202 and the drainage pipe 203, and finally flow into the smart water meter body 1 and the subsequent water supply pipe through the diversion pipe b102.

[0042] When the filter screen 701 needs to be replaced or cleaned, the staff can start the extension of the electric telescopic rod 9 inside the filter block 3, and drive the blocking piston a801, the fixing rod 8 and the blocking piston b802 to move downward along the diverter chamber 305 through the electric telescopic rod 9, so that the blocking piston a801 moves out of the diverter chamber 305, and the blocking piston b802 enters the diverter groove a306, so that the diverter chamber 305 and the filter chamber b302 are connected, and the water flow to the filter chamber a301 is blocked, so that the water enters the filter chamber b302 through the diverter groove a306 and the water inlet hole b309, and the water flowing into the filter chamber b302 is filtered with the help of the filter screen 701 inside the filter chamber b302, and finally the water is introduced into the box body 2 and the subsequent water supply pipeline through the diverter pipe a201 and the drainage pipe 203.

[0043] Furthermore, the user removes the bolts on the pull block 7, then pulls the filter 701 out of the filter block 3, and cleans or replaces the filter 701.
