Description

Technical Field

[0001] The utility model relates to the technical field of water meters, in particular to a large-caliber water meter supporting multiple communications. Background Art

[0002] A water meter is an instrument for measuring water flow, usually measuring the cumulative flow of water. Water meters are generally divided into two categories: volumetric water meters and velocity water meters. Large-diameter water meters refer to water meters with a nominal diameter of 50mm or above. Large-diameter water meters are also called industrial water meters. They use flange connections. By installing a signal transmitter inside the large-diameter water meter, the signal transmitter can transmit the data measured by the flow sensor to an external signal receiving device, making it convenient for staff to inquire through multiple channels.

[0003] For example, a large-diameter water meter supporting multiple communications is disclosed in the utility model with authorization announcement number CN218865199U. It inserts the water pipe into the groove of the inclined pipe and presses it against the sealing ring. The long plate is rotated to drive the vertical plate to be inserted into the water pipe to fix the position of the water pipe. The water in the water pipe enters the interior of the circular pipe through the inclined pipe and is detected by the flow sensor. The detection results are sent out by the signal transmitter, which makes it convenient for the staff to record the detection data.

[0004] This prior art also has the following problems when used:

[0005] The device rotates multiple long plates to drive the vertical plates to rotate upward. After the water pipe is installed, the long plates are loosened to allow the vertical plates to rotate downward and insert into the water pipe to fix the water pipe. However, when the water pipe is hard or is not provided with grooves or holes for convenient insertion of the vertical plates, it is difficult to insert the vertical plates into the water pipe when rotating downward, making it difficult to fix the water pipe.

A threaded ring 17 and four fixing boxes 18 are fixedly provided on the outside of the second round tube 7. The threaded sleeve 9 is threadedly connected to the outside of the threaded ring 17. A fixing ring 10 is fixedly provided on the side of the threaded sleeve 9. A guide block 21 is provided through the inside of the fixing box 18. The top surface of the guide block 21 is fixedly provided with an ramp 11. Symmetrical connecting plates 19 are fixedly provided on the left and right sides of the guide block 21. The top surface of the fixing box 18 is provided with a first slide groove and a second slide groove adapted to the connecting plate 19 and the guide block 21.

The bottom of the second slide groove The water pipe is placed inside the annular groove 8, and the threaded sleeve 9 is rotated to drive the fixing ring 10 to rotate until the fixing ring 10 contacts the inclined plate 11 at the same time. The threaded sleeve 9 continues to rotate to make the fixing ring 10 squeeze the inclined plate 11, driving the inclined plate 11 and the guide block 21 to move in the direction close to the outer wall of the water pipe. The reset spring 20 is compressed until the guide block 21 simultaneously extends into the annular groove 8 to clamp and limit the outer wall of the water pipe. Reverse rotation of the threaded sleeve 9 can drive the fixing ring 10 to disengage from the inclined plate 11, thereby causing the reset spring 20 to push the connecting plate 19 to drive the guide block 21 to disengage from the outer wall of the water pipe, thereby releasing the limit on the water pipe. The clamping assembly has a strong applicability to water pipes.

[0027] like Figure 1-Figure 4As shown, a length adjustment component is provided on the outside of the second circular tube 7, and the length adjustment component is composed of a swivel 12, a locking bolt 13, a movable ring 22, a sealing ring 23, an arc-shaped slider 24 and an arc-shaped slide groove 25. The inner wall of the annular groove 8 is slidably connected with a movable ring 22 that adapts to the annular groove 8, and a sealing ring 23 is fixedly provided on the side of the movable ring 22. The water pipe extends into the interior of the annular groove 8 and presses against the sealing ring 23 to improve the sealing effect of the water pipe. A symmetrical arc-shaped slider 24 is fixedly provided on the outside of the movable ring 22, and a swivel 12 is fixedly provided on the outside of the arc-shaped slider 24. The inner side of the swivel 12 is slidably connected to the outer side of the second circular tube 7, and a locking bolt 13 is provided through the outside of the swivel 12. The locking bolt 13 is threadedly connected to the swivel 12 Then, the locking bolt 13 extends into the interior of the swivel 12 and presses against the second circular tube 7 to fix the relative position of the swivel 12 and the second circular tube 7, thereby limiting the position of the movable ring 22. A symmetrical arc-shaped groove 25 is provided on the outside of the second circular tube 7. The arc-shaped groove 25 is connected to the annular groove 8. The arc-shaped slider 24 is adapted to the arc-shaped groove 25. The arc-shaped slider 24 is slidably connected to the second circular tube 7 through the arc-shaped groove 25. Rotating the locking bolt 13 drives the locking bolt 13 away from the second circular tube 7 to release the limit on the movable ring 22. Moving the swivel 12 left and right can drive the movable ring 22 to move left and right in the annular groove 8, thereby facilitating adjustment of the length of the water pipe extending into the annular groove 8 as needed.

[0028] Specific working principle:

[0029] When the device is used, the water pipe is placed inside the annular groove 8 and pressed against the sealing ring 23. The threaded sleeve 9 is rotated to drive the fixing ring 10 to rotate until the fixing ring 10 contacts the inclined plate 11 at the same time. The threaded sleeve 9 continues to rotate to cause the fixing ring 10 to squeeze the inclined plate 11, driving the inclined plate 11 and the guide block 21 to move toward the outer wall of the water pipe. The return spring 20 is compressed until the guide block 21 simultaneously extends into the annular groove 8 to clamp and limit the outer wall of the water pipe. The water in the water pipe enters the first circular pipe 1 through the inclined pipe 6 and is detected by the flow sensor 15. The digital display 5 can display the data measured by the flow sensor 15, making it convenient for workers to view it when approaching the housing 2. The signal transmitter 16 can transmit the detection data to an external signal receiving device, making it convenient for workers to inquire through multiple channels. When the flow sensor 15 completes the detection, the threaded sleeve 9 is rotated in the opposite direction to drive the fixing ring 10 to separate from the inclined plate 11, thereby causing the return spring 20 to push the connecting plate 19 to drive the guide block 21 to separate from the outer wall of the water pipe, releasing the limit on the water pipe and facilitating the removal of the water pipe.

[0030] When the device needs to adjust the length of the water pipe extending into the annular groove 8, rotating the locking bolt 13 drives the locking bolt 13 away from the second circular tube 7 to release the limit on the movable ring 22, and moving the rotating ring 12 left and right can drive the movable ring 22 to move left and right in the annular groove 8, thereby facilitating the adjustment of the length of the water pipe extending into the annular groove 8 as needed.
