Today, I will introduce a national invention authorized patent-a horizontal intelligent wired remote water meter. Hunan Weiming Energy Technology Co., Ltd. applied for the patent and obtained the authorization announcement on May 31, 2017.
Content descriptionThe utility model relates to an intelligent water meter, in particular to a horizontal intelligent wired remote water meter.
Background of the inventionThe 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 existing smart wired remote photoelectric direct-reading water meter is generally installed in the meter head due to its smart meter reading photoelectric module. In order to connect to external meter reading devices such as collectors and obtain power supply, the smart wired remote photoelectric water meter The photoelectric module must be connected to the collector through a communication line.
However, the traditional smart meter simply handles the communication line and exposes it directly to the outside, and can perform normal stopwatch work when the communication line is not damaged. However, due to the limitation of the installation environment of the water meter, the water meter is usually installed on a dark surface or in a pipeline well. If no protective measures are taken for the exposed communication line, it will be bitten by some harmful rodents such as mice. When the communication line is rodent After the skin is bitten or broken, the smart wired remote meter cannot perform normal remote meter reading.
Summary of the inventionThe purpose of the utility model is to provide a horizontal intelligent wired remote water meter with a communication line protection member connected to the base meter to ensure that the meter can perform normal remote meter reading at any time.
The horizontal 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 made of metal Passing through the hose is protected.

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 used for The rectangular boss connected to the metal hose is provided with a rectangular groove penetrating the wall of the fixing ring from bottom to top. The depth of the rectangular groove is less than the height of the wall of the fixing ring. An arc-shaped groove is opened from the inner edge to the outside. The front of the rectangular boss corresponds to the arc-shaped groove with a drum-shaped through hole. There is a pair on the inside of the wall of the fixing ring between the two pairs of joints and the rectangular boss. A symmetrically arranged elongated concave surface along the height direction of the fixing ring wall; the inner edge of the butt joint has a concave longitudinal blind groove for positioning the fixing ring after being installed on the base watch case.
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 the position of the lock nut, and the 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 metal hose includes a stainless steel corrugated tube, and a joint and a protective sheath connected to the inner and outer ends of the corrugated tube. The joints are 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 processed into planes, the outer wall of the middle of the length of the small cylindrical section is processed with a concave annular groove, 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 rectangular boss 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 by The E-shaped retaining ring in the annular groove on the small cylindrical section is limited. The stainless steel metal hose includes a stainless steel corrugated pipe with joints and a protective wire sleeve at both ends, and the joint and the protective wire sleeve are bonded with the stainless steel corrugated pipe by strong glue. The joint of the stainless steel metal hose is composed of three sections, the front end is a small circular cylindrical hole with plane milling on both sides, there is a concave circular groove in the middle of the small cylinder at the front end, and the middle section is a regular hexagonal hole. The connection between the rear section and the stainless steel corrugated pipe is a large circular cylindrical hole body; the protective wire sleeve is a small circular cylindrical hole body.
The utility model installs a fixed ring on the case of the base meter, and passes the communication line connected to the base meter through the metal hose connected with the fixed ring. The communication line is covered by the metal hose, so that the water meter is installed in a dark place. Harmful rodents will not be bitten on the surface or in the pipeline well, which ensures the normal remote meter reading work of the meter.
