[Meter's latest patent] A horizontal intelligent wired remote water meter

Content Description

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

Background of the invention

The existing smart wired remote water meters are generally photoelectric direct-reading water meters. Photoelectric direct-reading water meters are used to introduce optoelectronic technology and decoding direct-reading technology into direct-reading water meters. Direct-reading water meters are passive ones. The feature is that there is no need for a power supply at ordinary times, and the power supply is only needed at the instant of meter reading.

The existing smart wired remote optical direct-reading water meter is generally installed in the meter head due to its smart meter reading optical module, in order to connect the external meter reading assembly of the collector, and obtain the power supply, the smart wired remote water meter The optoelectronic module must be connected to the collector via a communication line.

However, the traditional smart meter only exposes the communication line directly after it is simply processed, and can perform normal stopwatch work when the communication line is not damaged. However, due to the installation environment of the water meter, the water meter is usually installed in a dark surface or in a pipeline well. If there is no protective measure for the exposed communication line, it will be bitten by some harmful rodents such as mice. When the communication line is rodent After the bite or bite is broken, the smart cable remote meter meter cannot perform normal remote meter reading.

Summary of the Invention

The purpose of the utility model is to provide a horizontal intelligent wired remote water meter connected with a protection component of a communication line on the base meter to ensure that the meter can perform normal remote meter reading work at any time.

The horizontal intelligent wired remote water meter provided by the utility model includes a base watch, a communication wire, a fixing ring connected to the base watch case, and a metal hose integrated with the fixing ring. The communication wire is from the metal. Passage in the hose is protected.

The figure is a schematic view of the main structure of an embodiment of the present invention

The fixing ring is an open circular ring structure made of plastic material, and the two ends of the wall body are respectively provided with convex pair joints, and are used at the wall body symmetrical to the radial center surface of the counter joint. The rectangular boss connected to the metal hose has a rectangular slot extending from the bottom to the top of the fixed ring wall. The depth of the rectangular slot is smaller than the height of the wall of the fixed ring, and the wall of the top surface of the rectangular slot An arc-shaped groove is formed from the inner edge to the outside, and a front surface of the rectangular projection is provided with a drum-shaped through hole corresponding to the arc-shaped groove, and a pair of inner walls of the fixing ring between the two pairs of the connector and the rectangular projection. Symmetrical arrangement, along the height direction of the wall of the fixed ring, is an elongated concave surface; the inner edge of the joint has an outer concave longitudinal blind slot for positioning after the retaining ring is mounted on the watch case.

One of the two pairs of joints is embedded with a locking nut for docking, and the other is provided with a corresponding round hole corresponding to the position of the locking nut. Between the two pairs of joints, lead passes through the round hole and the lock nut. The sealing screws are butt-locked.

The metal hose includes a stainless steel bellows and a joint and a grommet connected to the inner and outer ends thereof. The joint is a small cylindrical section, a regular hexagonal section and a large cylindrical section from the inside to the outside, and the size of the regular hexagonal section. The largest and small cylindrical segments are planes symmetrically with respect to the axial center plane and the pair of side faces are machined into planes. The central wall of the small cylinder segment is machined 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 fixed 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 each other. E-ring stop in an annular groove on a small cylindrical section. The stainless steel metal hose includes a stainless steel corrugated pipe, joints at both ends and a wire protecting sleeve, and the joint and the wire protecting sleeve and the stainless steel corrugated pipe are bonded by using strong glue. The joint of the stainless steel metal hose is composed of three segments, the front end is a small circular column hole body with two planes milled on the two sides, and the front small cylinder has a recessed annular groove in the middle, and the middle section is a regular hexagonal hole body. The connection between the rear section and the stainless steel corrugated pipe is a large circular-ring column body; the sheath is a small ring-shaped column body.

According to the utility model, a fixing ring is mounted on the watchcase of the base watch, the communication wire connecting the base watch is passed through the metal hose connected with the fixing ring, and the communication wire is covered by the metal hose, so that the water meter is installed even in the dark No harmful rodents will be bitten on the ground or in pipeline wells, guaranteeing the meter's normal remote-reading meter reading.
