Description

Technical Field

[0001] The utility model belongs to the technical field of water meters, and in particular relates to an NB-IOT non-magnetic valve-controlled cold water meter. Background Art

[0002] A non-magnetic water meter refers to a fully electronic water meter that picks up signals through non-magnetic technology. It has a long service life, is not affected by strong magnetic interference, can work normally in a strong magnetic environment, and ensures metering accuracy. NB-IoT, or narrowband Internet of Things, is an emerging technology in the IoT field that supports cellular data connections of low-power devices in wide area networks. NB-IOT supports efficient connection of devices with long standby time and high network connection requirements. Applying NB-IOT to non-magnetic water meters can effectively improve the performance of water meters.

[0003] The NB-IOT non-magnetic valve-controlled water meter is a measuring instrument composed of a cast iron water meter, an NB-IOT transmission unit, a mechanical metering unit and a protective cover. The protective cover is equipped with a flap structure to block external impurities while quickly observing the usage flow. At present, the water meters are installed in a dark and narrow environment, and multiple water meters are neatly arranged from top to bottom in one area, so that after the flap structure of the protective cover is opened, the flap itself will affect the observation of outsiders, and the staff needs to use external lighting equipment to illuminate and observe it. The flap will block the light to a certain extent, and because the environment is small, the lighting equipment will illuminate the water meter while the staff is difficult to observe. The head or torso of the staff is easy to block the light, and the two will affect each other's position to a certain extent. In addition, when the staff finishes checking the flow measurement, if the staff forgets to close the flap, the protective seal of the protective cover will be affected to a certain extent. So far, the design of the existing NB-IOT non-magnetic valve-controlled water meter protective cover structure needs to be improved.

[0004] Therefore, it is very necessary to invent a NB-IOT magnetic-free valve-controlled cold water meter. Utility Model Content

[0007] Preferably, a transparent cover is installed on the protective cover, and the transparent cover is arranged below the knob cover, and the knob cover is composed of a rotary cover part and an axial part.

[0008] Preferably, the vertical shaft is a 'T'-shaped structure, and the vertical shaft is elastically connected to the axial center of the knob cover through a clockwork spring.

[0009] Preferably, the fingertip groove is a circular groove, the anti-slip indication protrusion arranged on one side of the fingertip groove is a 'V'-shaped protrusion structure, and a plurality of anti-slip indication protrusions are arranged.

The screw-cover structure provided in the knob-type protective cover is a cover structure that is rotated open within a horizontal range, and has an automatic resetting function to prevent the subsequent sealing from being affected. It can be well applied to the installation method of multiple water meters arranged neatly from top to bottom.

[0023] Embodiment 1:

[0024] Specifically, a transparent cover is installed on the protective cover 61 , and the transparent cover is arranged below the knob cover 64 . The knob cover 64 is composed of a rotary cover portion and an axial portion. A sealing rubber ring is arranged inside the protective cover 61 .

[0025] Specifically, the vertical shaft 62 is a 'T'-shaped structure, and the vertical shaft 62 is elastically connected to the axis of the knob cover 64 through a spring spring 63 . The spring spring 63 is used to drive the knob cover 64 to reset through the spring elastic force and force the knob cover 64 to be in close contact with the limit stop body 68 .

[0026] Specifically, the fingertip groove 66 is a circular groove, and the anti-skid indicating protrusion 67 provided on one side of the fingertip groove 66 is a 'V'-shaped protrusion structure.

[0028] Embodiment 2:

[0029] The defects or problems raised in the above-mentioned background technology are mainly solved by the structure of the knob-type protective cover 6: when the staff needs to check the flow measurement of the water meter, the staff's index finger or middle finger is placed in the fingertip groove 66 of the knob-type protective cover 6, and an outward pulling force is applied to it, and the knob cover 64 of the knob-type protective cover 6 is driven to rotate outward by the finger. During the rotation of the knob cover 64, the knob cover 64 will compress the clockwork spring 63, and the clockwork spring 63 will shrink. At this time, after the knob cover 64 rotates to a certain extent, the knob cover 64 will press the trigger switch 65 on one side, and the trigger switch 65 turns on the lighting lamp 610 installed on the limit resistance body 68 for operation. The light generated by the lighting lamp 610 passes through the transparent cover and the transparent cover to shine on the mechanical metering part 4, and the staff can observe it. When the observation is completed, after the staff releases their fingers, the clockwork spring 63 drives the knob cover 64 to reset through the spring elastic force, thereby avoiding the situation where the staff forgets to close it and affects the sealing effect.
