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

Content Description

The utility model relates to an intelligent water meter, in particular to a vertical 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 optoelectronic module is generally installed in the meter head. To connect the external meter reading assembly of the collector and obtain the power supply, the optoelectronic module in the smart cable remote transmission meter must be connected to the collector through the communication line.

Smart wired remote water meters have horizontal water meters and vertical water meters. However, for the vertical water meters, because the outlet of the communication line on the base meter needs to face outward, the current practice is to reversely install the meter head. . This type of meter installed with a reversed meter does not have much impact on the user. However, the water meter verification personnel of the Water Department need to turn the offset head at least 90 degrees to read the meter normally, and it is easy to copy the wrong data. Therefore, the direction of the existing header installation method causes the verification personnel to cause extremes in the flow detection. Big inconvenience.

Summary of the Invention

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

The vertical 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 hose. The middle pass is protected, and there is a threading groove on the fixed ring that changes the communication line to the outgoing line position.

The figure is a three-dimensional structure diagram of an embodiment of the present invention

The fixing ring is an open circular ring structure made of a plastic material. The two ends of the wall body are respectively provided with convex pair joints, and are arranged at the wall body symmetrical to the radial center surface of the counter joint. An inlet port of the communication line is provided with a communication line outlet on the wall of the fixed ring on the side of the connector. The threading slot is located between the inlet and the outlet; one of the two pairs of connectors is used for mounting. A corresponding round hole is provided at the position of the lock nut corresponding to the butt-joined lock nut, and the two pairs of joints are butt-locked by a sealing screw passing through the round hole and the lock nut. The inlet is an upper arc groove and a lower rectangular groove, wherein the width of the lower rectangular groove is larger than the width of the upper arc groove.

The threading groove is a C-arc hole in which a rectangular groove at the lower part of the entrance is continuous and arranged in a staggered manner along the circumference of the fixing ring wall. The C-arc hole of the fixing ring wall facing downward is corresponding to the direction. The lower part of the hole is hollowed out and the upper part of the C-shaped arc hole facing upwards is hollowed out.

The outer side edge of the C-arc hole disposed downwards is in the form of a tine, and the outer side edge of the C-arc hole disposed in the upward direction is blunt. The outlet opening is a rectangular hollow convex protruding outwards, and the sidewall of the rectangular convex opening is provided with a drum-shaped through hole. 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 at the outlet opening of 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 through the small hole. E-ring stop in a circular groove in a cylindrical section.

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.

In the utility model, the fixing ring of the threading groove is installed on the base table, the threading position of the communication line is changed through the threading groove on the fixing ring, and after the meter head is installed forward, the communication line direction of the meter head is still from the front side. Outgoing, so that the verification staff do not have to turn around when reading the meter, but also can guarantee the accuracy of the data of the meter reading, reduce the difficulty of the inspection station verification personnel, and improve the meter verification efficiency. At the same time, the metal hose connected with the fixing ring covers the communication line to prevent the rodent from biting the communication line.
