Description

Technical Field

[0001] The utility model relates to the technical field of water meters, in particular to a volumetric direct drinking water meter. Background Art

[0002] Volumetric water meters are mainly installed in pipes. They are composed of some chambers with known volumes that are filled and discharged successively and a mechanism driven by the fluid. They are also called quantitative discharge water meters for short. Volumetric water meters are different from velocity water meters. The most vivid metaphor is like the revolving door in front of a large supermarket or hotel, which can only rotate in a fixed direction. Every time it rotates a certain angle, the fluid will go to the other side through the water meter. Therefore, the measurement of volumetric water meters is more accurate than that of velocity water meters.

[0003] During use, the existing volumetric water meter mainly utilizes water pressure to drive the blades to rotate, thereby achieving the metering effect. Due to the acceleration generated when the blades rotate, after the valve is closed, it is easy for the blades to continue to rotate, thereby reducing the accuracy of the water meter measurement. In addition, for the inspection and maintenance of the water meter, if it is impossible to determine whether the water meter is blocked inside, the water meter often needs to be disassembled for inspection. If there is no blockage inside the water meter, the workload of the staff is increased. Utility Model Content

[0004] In view of the shortcomings of existing water meters, the utility model provides a volumetric direct drinking water meter, which has the advantages of causing the blades to stop rotating quickly after the valve is closed, thereby improving the accuracy of the water meter and judging whether the water meter is in normal operation by the position of the magnetic beads, thus solving the technical problem that the blades continue to rotate due to their own acceleration after the valve is closed.

[0005] The utility model provides the following technical solution: a volumetric direct drinking water meter, comprising a meter case, and also comprising:

[0006] A water inlet pipe is fixedly installed in the middle of the left side wall of the case, a water outlet pipe is fixedly installed in the middle of the right side wall of the case corresponding to the water inlet pipe, a partition is fixedly connected to the top surface of the case, a metering device is fixedly installed on the top surface of the partition, a baffle is fixedly connected to the inner side wall of the metering device, and a rotating shaft is rotatably sleeved in the middle of the baffle;

[0007] A rotating block is fixedly sleeved on the outer surface of the rotating shaft located in the inner cavity of the watch case, a blade is fixedly connected to the outer surface of the rotating block, a metering mechanism is fixedly sleeved on the outer surface of the rotating shaft located on the upper side of the baffle, an indicating device is fixedly installed on the inner side wall of the metering device located on the upper side of the baffle, and a watch cover is hinged on the top surface of the metering device through a hinge.

[0008] Preferably, the water inlet pipe comprises:

[0009] A mounting plate fixedly connected to the middle of the side wall of the water inlet pipe;

[0010] A cross bar, fixedly connected to the middle of the side of the mounting plate facing the water inlet pipe;

[0011] The movable cavity is arranged inside the cross bar.

[0012] Preferably, the interior of the activity chamber includes:

[0013] A strong magnetic slider, slidably connected to the inside of the active cavity;

[0014] A spring, fixedly connected to the middle of the side of the strong magnetic slider facing the inner cavity of the watch case;

[0015] A through hole is provided on the side wall of the cross bar;

[0016] The connecting rope is fixedly connected to the side of the strong magnetic sliding block facing the water inlet pipe.

[0017] Preferably, the mounting plate comprises:

[0018] A gear lever, slidably sleeved inside the mounting plate and located on both sides of the crossbar;

[0019] A limit plate, fixedly connected to one end of the stop rod facing the water inlet pipe;

[0020] A tension spring is fixedly connected to the middle part of the side surface of the limiting plate facing the mounting plate, and the limiting plate is fixedly connected to the connecting rope.

[0021] Preferably, the water inlet pipe comprises:

[0022] A fixing block, fixedly connected to the outer surface of the water inlet pipe;

[0023] A movable groove is provided on the top of the fixed block;

[0024] Magnetic beads are movably placed inside the movable groove, and the magnetism of the magnetic beads is opposite to the magnetism of the strong magnetic slider.

[0025] Compared with the prior art, the utility model has the following beneficial effects:

[0026] 1. By designing the mounting plate, cross bar, strong magnetic slider, connecting rope, stopper and limit plate, when the water meter is used normally, since the water flow enters from the water inlet pipe, the pressure of the water flow will push the strong magnetic slider to slide into the inside of the active cavity, so that the strong magnetic slider will exert tension on the connecting rope, so that the connecting rope pulls the limit plate and the stopper to slide to the side of the water inlet pipe. When the valve is closed, the pressure of the water flow on the strong magnetic slider is removed, so that the strong magnetic slider will slide under the potential energy of the spring, and then the tension spring will drive the limit plate and the stopper to move in the direction of the blade, and then the stopper will be horizontal on the rotation trajectory of the blade and block the blade, so as to achieve the effect of rapid stopping of the blade, thereby improving the accuracy of water meter measurement.

[0027] 2. By designing the fixed block, movable groove and magnetic beads, when the water meter is used normally, the water flow pushes the strong magnetic slider to slide into the movable cavity. At this time, the magnetic attraction of the strong magnetic slider to the magnetic beads causes the magnetic beads to slide inside the movable groove and move to the upper side of the movable groove. Since the movable groove is inclined, when the valve is closed, the strong magnetic slider is not impacted by the water flow, so that the strong magnetic slider will absorb the magnetic beads and slide to the bottom of the movable groove after resetting. Therefore, when the staff inspects the water meter, they only need to open the valve to observe the position of the magnetic beads to determine whether the inside of the water meter is blocked, without disassembling it for observation, thereby reducing the workload of the staff.

[0035] See also Figure 1-Figure 4 A mounting plate 21 is fixedly welded to the middle of the side wall of the water inlet pipe 2 , a cross bar 22 is fixedly welded to the middle of the side of the mounting plate 21 facing the water inlet pipe 2 , and an active cavity 23 is opened inside the cross bar 22 .

[0036] See also Figure 1-Figure 4 A strong magnetic slider 24 is slidably connected inside the active cavity 23 to ensure that water flows into the water inlet pipe 2 and directly impacts the strong magnetic slider 24, thereby pushing the strong magnetic slider 24 to move. A spring 25 is fixedly welded to the middle of the side of the strong magnetic slider 24 facing the inner cavity of the watch case 1 for resetting the strong magnetic slider 24. A through hole 26 is provided on the side wall of the cross bar 22. A connecting rope 27 is fixedly connected to the side of the strong magnetic slider 24 facing the water inlet pipe 2 to ensure that the connecting rope 27 can pass through the through hole 26.

[0037] See also Figure 1-Figure 4 , the interior of the mounting plate 21 is located on both sides of the cross bar 22 and is slidably sleeved with a gear rod 28. A limit plate 281 is fixedly welded to one end of the gear rod 28 facing the water inlet pipe 2, so that the blade 9 can be limited when the gear rod 28 extends into the interior of the watch case 1, ensuring that the blade 9 can quickly stop rotating. A tension spring 282 is fixedly welded to the limit plate 281 toward the middle of the side of the mounting plate 21.

[0038] See also Figure 1-Figure 4 A fixed block 29 is fixedly welded on the upper outer surface of the water inlet pipe 2, and a movable groove 291 is opened on the top of the fixed block 29. A magnetic bead 292 is movably placed inside the movable groove 291.

[0039] Working principle: when the water meter is in normal use, since the water flows in from the water inlet pipe 2, the pressure of the water flow will push the strong magnetic slider 24 to slide into the inside of the active cavity 23, so that the strong magnetic slider 24 will apply tension to the connecting rope 27, so that the connecting rope 27 pulls the limit plate 281 and the gear lever 28 to slide to the side of the water inlet pipe 2. When the valve is closed, the pressure of the water flow on the strong magnetic slider 24 is removed, so that the strong magnetic slider 24 will slide under the potential energy of the spring 25, and then the tension spring 282 will drive the limit plate 281 and the gear lever 28 to move in the direction of the blade 9, and then the gear lever 28 will be horizontal on the rotation trajectory of the blade 9 and block the blade 9, so as to achieve the effect of quickly stopping the blade 9 and improve the water The meter measurement accuracy is improved. At the same time, when the water meter is operating normally, the water flow is used to push the strong magnetic slider 24 to slide into the active cavity 23. At this time, the strong magnetic slider 24 exerts a magnetic attraction on the magnetic beads 292, so that the magnetic beads 292 slide inside the active groove 291 and move to the upper side of the active groove 291. Since the active groove 291 is inclined, when the valve is closed, the strong magnetic slider 24 is not impacted by the water flow, so that the strong magnetic slider 24 will absorb the magnetic beads 292 and slide to the bottom of the active groove 291 after resetting. Therefore, when the staff inspects the water meter, they only need to open the valve to observe the position of the magnetic beads 292 to determine whether the inside of the water meter is blocked, without having to disassemble it for observation, thereby reducing the workload of the staff.
