[0002] A water meter is an instrument that measures water flow, most of which measure the cumulative flow of water. It is generally divided into two categories: volumetric water meters and velocity water meters. It originated in the UK and has a history of nearly two hundred years. When choosing the specifications of a water meter, you should first estimate the size and flow range of the flow rate used under normal circumstances, and then choose the water meter with the specification that is closest to the commonly used flow rate as the first choice.

[0003] Existing water meters monitor water flow based on the time and speed of water flow, and staff can record the monitored water flow data.

[0004] However, existing water meters are affected by factors such as water flow velocity and water flow volume, which may cause internal metering devices to become disordered, resulting in inaccurate monitoring data. Utility Model Content

[0011] Beneficial effects

[0012] The utility model provides a water meter capable of monitoring flow. The water meter capable of monitoring flow has the following beneficial effects: The water meter capable of monitoring flow utilizes a wheel, a counter, and a thrust bearing seat to cooperate with each other. When water flows into the interior of a housing, the wheel rotates under the thrust of the water flow. The bottom of the wheel is rotatably connected to the inner wall of the thrust bearing seat via a lower shaft, and the top of the wheel is rotatably connected to the inner wall of the upper cover via an upper shaft.

[0013] Through the cooperation between the shell, the second sealing gasket and the extension tube, when the water meter is installed, if the installation gap cannot be adjusted, the water meter can be telescopically adjusted to adapt to different installation gaps by relying on the socket relationship between the inner wall of the extension tube and the outer wall of the shell. After adjustment, the extension tube and the shell can be fixed in position with bolts to prevent sliding. The effect of the second sealing gasket ensures that there will be no leakage when water flows through the shell and the extension tube. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described 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.

[0020] Existing water meters are affected by factors such as water flow velocity and volume, which may cause internal metering devices to become disordered, resulting in inaccurate monitoring data.

[0021] In view of this, the utility model provides a water meter that can monitor flow. Through the cooperation between the waist wheel, the counter and the thrust bearing seat, when water flows into the interior of the shell, the waist wheel rotates under the action of the thrust of the water flow. The bottom of the waist wheel is rotatably connected to the inner wall of the thrust bearing seat through the lower shaft, and the top of the waist wheel is rotatably connected to the inner wall of the upper cover through the upper shaft. The waist wheel can rotate one circle according to the thrust of the water flow, and the counter can jump to realize the monitoring of the water flow.

[0022] By those skilled in the art, the components in this case are connected in sequence. The specific connection and operation sequence should refer to the following working principle. The detailed connection means are well-known technologies in this field. The following mainly introduces the working principle and process.

[0023] Example 1: By Figure 1-4It can be seen that a water meter capable of monitoring flow rate includes a housing 1, the top of the housing 1 is fixedly connected to an upper cover 6, the bottom of the housing 1 is fixedly connected to a lower cover 15, and a metering device is provided inside the housing 1. The metering device includes a counter 9, an upper shaft 10, a waist wheel 11, a thrust bearing seat 16, and a lower shaft 18. The thrust bearing seat 16 is fixedly connected to the inner wall of the lower cover 15, and the inner wall of the thrust bearing seat 16 is rotatably connected to the lower shaft 18 through a thrust bearing. The bottom of the lower shaft 18 passes through the bottom of the lower cover 15 and is equipped with a flow meter 7. , the thrust bearing can specifically bear the axial force, ensuring the stability and safety of the mechanical components during operation. The top of the lower shaft 18 is fixedly connected with the waist wheel 11, the outer wall of the waist wheel 11 is rotatably connected to the inner wall of the shell 1, and the top of the waist wheel 11 is fixedly connected with the upper shaft 10. The outer wall of the upper shaft 10 is rotatably connected to the inner wall of the upper cover 6 through the radial bearing. The radial bearing can bear radial loads, ensuring the stability and safety of the waist wheel 11 during operation. The top of the upper shaft 10 passes through the top of the upper cover 6 and is installed with a counter 9;

[0024] During the specific implementation process, it is worth noting that when water flows into the interior of the housing 1, the waist wheel 11 rotates under the action of the thrust of the water flow. The bottom of the waist wheel 11 is rotatably connected to the inner wall of the thrust bearing seat 16 through the lower shaft 18, and the top of the waist wheel 11 is rotatably connected to the inner wall of the upper cover 6 through the upper shaft 10. The waist wheel 11 can rotate one circle according to the thrust of the water flow, and the counter 9 can jump to realize the monitoring of the water flow. According to the different flow rates of the water flow, the speed of the waist wheel 11 is different. The flow meter 7 can monitor the rotation of the waist wheel 11 in real time, that is, the water flow is monitored in real time.

[0025] Furthermore, the inner wall of the shell 1 is covered with a first sealing gasket 14, and the upper and lower ends of the waist wheel 11 are respectively rotatably connected to the inner wall of the first sealing gasket 14. The first sealing gasket 14 can ensure that water does not leak out of the outside of the shell 1, and the upper and lower ends of the waist wheel 11 are rotatably connected to the inner wall of the first sealing gasket 14. The outer wall of the waist wheel 11 is sleeved with a limit plate 12 and movably connected to the limit plate 12. The limit plate 12 is fixedly connected to the inner wall of the shell 1;

[0026] In the specific implementation process, it is worth noting that the first sealing gasket 14 can ensure that the water flow does not leak out of the outside of the housing 1, and the upper and lower ends of the waist wheel 11 are rotatably connected to the inner wall of the first sealing gasket 14. Due to the presence of the limit plate 12, the waist wheel 11 can only rotate on the inner wall of the limit plate 12 when rotating, and there will be no rotation deviation, thereby ensuring the accuracy of monitoring the water flow;

[0027] Furthermore, a dresser 8 is installed at the bottom of the counter 9, and an outlet shaft seal 17 is installed at the bottom of the dresser 8. The bottom of the outlet shaft seal 17 is installed at the top of the upper cover 6;

[0028] In the specific implementation process, it is worth noting that the dresser 8 can reset the counter 9, and the shaft seal 17 can prevent the loss of lubricant and the invasion of external impurities to ensure normal operation;

[0029] Specifically, when using the water meter capable of monitoring flow, when water flows into the interior of the housing 1, the waist wheel 11 rotates under the action of the thrust of the water flow, and the bottom of the waist wheel 11 is rotatably connected to the inner wall of the thrust bearing seat 16 through the lower shaft 18, and the top of the waist wheel 11 is rotatably connected to the inner wall of the upper cover 6 through the upper shaft 10. The waist wheel 11 can rotate one circle according to the thrust of the water flow, and the counter 9 can jump to realize the monitoring of the water flow. According to the different flow rates of the water flow, the speed of the waist wheel 11 is different, and the flow meter 7 can adjust the speed of the waist wheel 11. The rotation is monitored in real time, that is, the water flow is monitored in real time. The first sealing gasket 14 can ensure that the water flow will not leak out of the outside of the shell 1, and the upper and lower ends of the waist wheel 11 are rotatably connected to the inner wall of the first sealing gasket 14. Due to the existence of the limit plate 12, the waist wheel 11 can only rotate on the inner wall of the limit plate 12 when rotating, and there will be no rotation deviation, which ensures the accuracy of monitoring the water flow. The trimmer 8 can reset the counter 9, and the shaft seal 17 can prevent the loss of lubricant and the invasion of external impurities to ensure normal operation.

[0030] Example 2: By Figure 1-4 It can be seen that the inner wall of the housing 1 is fixedly connected with a filter plate 2;

[0031] In the specific implementation process, it is worth noting that when the water flows through the filter plate 2, the filter plate 2 can filter out impurities in the water to achieve the effect of purifying the water;

[0032] Furthermore, a water inlet 13 is provided on one side of the housing 1, an extension tube 3 is sleeved on the other side of the outer wall of the housing 1, the inner wall of the extension tube 3 is covered with a second sealing gasket 5, and a water outlet 4 is provided on the side of the extension tube 3 away from the water inlet 13. The water inlet 13 and the water outlet 4 are both processed into flange shapes. This water meter is installed between fixed pipes and can be adjusted according to the distance between the pipes. After adjustment, the extension tube 3 and the housing 1 can be fixed in position with bolts to prevent sliding.

[0033] In the specific implementation process, it is worth noting that when the water meter is installed, if the installation gap cannot be adjusted, the water meter can be telescopically adjusted by relying on the sleeve connection between the inner wall of the extension tube 3 and the outer wall of the housing 1 to adapt to different installation gaps. The second sealing gasket 5 ensures that no leakage occurs when water flows through the housing 1 and the extension tube 3.

[0034] Specifically, based on the above-mentioned embodiment 1, when water flows through the filter plate 2, the filter plate 2 can filter impurities in the water to achieve the effect of purifying water. If the installation gap cannot be adjusted, the inner wall of the extension tube 3 and the outer wall of the shell 1 can be connected to each other to achieve the telescopic adjustment of the water meter to adapt to different installation gaps. Relying on the function of the second sealing gasket 5, it is ensured that no leakage will occur when the water flows through the shell 1 and the extension tube 3.
