The working principle and design of the vertical intelligent wired remote water meter

Today, I will introduce a national invention authorized patent-a vertical intelligent wired remote water meter. The patent was applied for by Hunan Weiming Energy Technology Co., Ltd., and the authorization was announced on May 24, 2017.

Content description

The utility model relates to an intelligent water meter, in particular to a vertical intelligent wired remote transmission water meter.

Background of the invention

The existing smart wired remote water meter is generally a photoelectric direct-reading water meter. The photoelectric direct-reading water meter introduces photoelectric technology and decoding direct-reading technology into the direct-reading water meter. The direct-reading water meter is a passive meter with the largest The characteristic is that it does not need power supply at ordinary times, but it only needs power supply at the moment of meter reading. The photoelectric module is generally installed in the meter head. In order to connect the external meter reading device such as the collector and obtain the power supply, the photoelectric module in the smart wired remote water meter must be connected to the collector through a communication line.

Smart wired remote water meters are divided into horizontal water meters and vertical water meters, but for vertical water meters, since the outlet slot of the communication line on the base meter needs to face outwards, the current approach is to install the meter head in reverse. . This kind of vertical meter with the meter head installed in reverse has little effect on the user. However, the water meter verifier of the Water Division needs to turn the deflection head at least 90 degrees to read the water meter in order to read the meter normally, and it is easy to read the wrong data. Therefore, the existing way of installing the meter head causes a serious problem for the verifier when performing flow detection. Great inconvenience.

Summary of the invention

The purpose of the utility model is to provide a vertical intelligent wired remote water meter whose metal hose and communication line can still be drawn from the front end after the meter head is installed in the forward direction, so that the water meter appraiser can read the meter conveniently and accurately.

The vertical intelligent wired remote water meter provided by the utility model includes a base meter, a communication line, a fixed ring connected to the base watch case, and a metal hose connected to the fixed ring. The communication line is from the metal hose The middle thread is protected, and there is a threading groove on the fixed ring to change the position of the communication line.

The working principle and design of the vertical intelligent wired remote water meter

The fixed ring is an open circular ring structure and is made of plastic material. The two ends of the wall are respectively provided with convex butt joints, and the wall symmetrical to the butt joint with respect to the radial center plane is provided with The wire inlet of the communication line is provided with an outlet of the communication wire on the wall of the fixed ring on the side of the connector, and the threading groove is located between the wire inlet and the wire outlet; one of the two pairs of connectors is embedded with For the butted lock nut, a corresponding round hole is opened at the position of the other pair of joints corresponding to the lock nut, and the two pairs of joints are butted and locked as a whole by the lead sealing screw passing through the round hole and the lock nut. The wire inlet has a structure of an upper arc groove and a lower rectangular groove, wherein the width of the lower rectangular groove is greater than the width of the upper arc groove.

The threading groove is a section of C-shaped circular arc holes that are successively arranged along the circumference of the fixed ring wall and the corresponding direction of the fixed ring wall faces downwards. The lower part of the hole is hollowed out, and the upper part of the C-shaped arc hole with the corresponding direction facing upward is hollowed out.

The outer side edge of the C-shaped circular arc hole arranged downward is tine-shaped, and the outer side edge of the C-shaped circular arc hole arranged upward is crenellated. The outlet is a rectangular boss with hollow inside and convex, and the side wall of the rectangular boss is provided with a drum-shaped through hole. The metal hose includes a stainless steel corrugated tube, and a joint and a protective wire sleeve connected to the inner and outer ends of the corrugated tube. The joint is composed of a small cylindrical section, a regular hexagonal section and a large cylindrical section from the inside to the outside. The size of the regular hexagonal section is The largest, a pair of symmetrical sides of the small cylindrical section with respect to the axial center plane are machined into planes, a concave annular groove is machined on the outer wall of the middle of the length of the small cylindrical section, and the axial center of the joint is a through hole.

The small cylindrical section of the joint passes through the drum-shaped through hole of the outlet on the fixing ring, the regular hexagonal section of the joint is located outside the drum-shaped through hole, and the small cylindrical section and the rectangular boss are connected to the small through hole. The E-shaped retaining ring in the annular groove on the cylindrical section is limited.

One of the two pairs of joints is embedded with a lock nut for butting, and the other pair of joints is provided with a corresponding round hole at a position corresponding to the lock nut, and a lead passing through the round hole and the lock nut is passed between the two pairs of joints. The sealing screws are butt-locked as a whole.

The utility model installs a fixed ring with a threading groove on the base meter, and changes the outlet position of the communication line through the threading groove on the fixed ring, so that after the meter head of the water meter is installed in the forward direction, the direction of the communication line of the meter head is still from the front side This way, the verifier does not need to turn his head when reading the meter, and at the same time, it can ensure the accuracy of the meter reading data, reduce the work difficulty of the verifier at the testing station, and improve the efficiency of water meter verification. At the same time, the metal hose connected to the fixed ring wraps the communication line to prevent rodents from biting the communication line.
