Description

Technical Field

[0001] The utility model belongs to the technical field of water services, and particularly relates to a flow monitoring device for a water meter. Background Art

[0002] A water flow monitoring device, also known as a flowmeter, outputs detection data through the induction of water flow, and the controller processes it to generate water flow data, which can be used for water control management and flow calculation. When in use, the water flow monitoring device is pre-installed in the water meter. However, when the pre-installed water flow monitoring device in the water meter malfunctions during use, the entire water meter needs to be disassembled, repaired, and maintained, resulting in high maintenance costs. Therefore, a water flow monitoring device that is easy to disassemble and independent is required.

[0003] A flow monitoring device for a water meter according to a formula (Publication No.: CN 220063071U): includes a sleeve, with connecting parts provided at both ends of the sleeve; an impeller assembly, including a mounting frame detachably installed inside the sleeve and an impeller axially connected to the mounting frame, and the axial direction of the impeller is parallel to the axial direction of the sleeve; an inductor, installed on the impeller and continuously sensing the rotation speed and time of the impeller; a controller, which processes and generates water flow data according to the rotation speed and time.

[0004] In the above application, through the mutual cooperation of the sleeve and the impeller assembly, when monitoring the water flow in the sleeve, it is difficult to solve the function of controlling the flow rate, resulting in the inability to adjust according to daily needs when the water volume is constant. Therefore, we propose a flow monitoring device for a water meter. Content of the Utility Model

The staff can use the flow control mechanism according to the demand. By adjusting the telescopic length of the telescopic end of the electric telescopic rod, the adjusting water baffle controls the size of the flow.

The end of the return spring 47 away from the inner wall of the annular hydraulic cylinder 42 is fixedly connected to the side of the connecting block 45. The function of the end of the return spring 47 away from the inner wall of the annular hydraulic cylinder 42 being fixedly connected to the side of the connecting block 45 is that when the regulating water baffle 46 does not need to be adjusted, the connecting block 45 can be reset through the elasticity of the return spring 47. The function of the side of the installation frame 2 being rotatably connected with a rotating shaft 48 is that the rotating shaft 48 rotates through the impact force of the water pressure on the blade 49.

A moving groove 59 is formed in the circumferential surface of the sleeve 1. The inside of the moving groove 59 is slidably connected to the side of the connecting rod 58. An annular cleaning brush 510 is fixedly connected to the side of the connecting rod 58. The function of arranging the cleaning mechanism 5 inside the sleeve 1 is to prevent excessive debris from accumulating inside the sleeve 1 during long-term operation, causing blockage.

[0033] A cleaning port 511 is formed in the inner wall of the sleeve 1. A baffle 512 is slidably connected to the inner wall of the sleeve 1.

The function of the side of the baffle 512 being on the displacement trajectory of the annular cleaning brush 510 is to ensure that the annular cleaning brush 510 can push the baffle 512 during the moving process.

[0035] A specific application of this embodiment is as follows: First, when the monitoring device is installed at the position to be monitored, when the water pressure caused by the flow inside the pipeline passes through the inside of the sleeve 1, the water pressure caused by the water flow makes the blade 49 drive the rotating shaft 48 to rotate, and the rotational speed is converted into a flow value and displayed on the water meter 3. At this time, the staff can use the flow control mechanism 4 as needed, start the electric telescopic rod 41, and the telescopic end of the electric telescopic rod 41 moves downward. During the movement of the telescopic end of the electric telescopic rod 41, it pushes the force-bearing rod 43 of the annular hydraulic cylinder 42, and the force-bearing rod 43 retracts into the annular hydraulic cylinder 42 under the thrust. At the same time, the hydraulic rod 44 of the annular hydraulic cylinder 42 extends outward under the pressure of the liquid inside the annular hydraulic cylinder 42. The outward extension of the hydraulic rod 44 drives the adjustment water baffle 46 to adjust the size of the water inlet of the sleeve 1 through the connecting block 45. By the telescopic length of the telescopic end of the electric telescopic rod 41, the adjustment water baffle 46 controls the size of the flow. When the flow size does not need to be adjusted, the adjustment water baffle 46 is reset through the elasticity of the connecting block 45 and the return spring 47.

[0036] When the sleeve 1 is used for a long time, sundries in the water flow will accumulate inside the sleeve 1 to prevent the inside of the sleeve 1 from being blocked. At this time, start the electric telescopic rod 41, and the telescopic end of the electric telescopic rod 41 moves downward. The downward movement of the telescopic end of the electric telescopic rod 41 drives the first rack 52 to move downward through the support rod 51. Because the first rack 52 meshes with the gear 54 and the gear 54 meshes with the second rack 57, the downward movement of the first rack 52 drives the gear 54 rotatably connected to the mounting plate 53 to rotate counterclockwise. The counterclockwise rotation of the gear 54 drives the second rack 57 to move from left to right inside the sliding groove 55 through the sliding column 56. The connecting rod 58 fixed to the bottom of the second rack 57 follows the second rack 57 to move from left to right inside the moving groove 59. The movement of the connecting rod 58 from left to right drives the annular cleaning brush 510 to move from left to right inside the sleeve 1. During the movement of the annular cleaning brush 510, it pushes the baffle 512 to move from left to right, thereby opening the cleaning port 511, so that the sundries cleaned by the annular cleaning brush 510 leave the inside of the sleeve 1 through the cleaning port 511.
