Detailed Description

The following description of the present invention will be further described with reference to the accompanying drawings, and the embodiments of the present invention are only used for illustrating the present invention and not for limiting the present invention, and various replacements and modifications can be made according to the common technical knowledge and the conventional means in the field without departing from the technical idea of the present invention, and all should be included in the scope of the present invention.

As shown in fig. 2, a water meter with a data output interface comprises a meter shell 2, an impeller 3 and a gear transmission counting mechanism 4, wherein the meter shell 2 is sealed by a seal 13 to form a packaging area; the packaging area is provided with at least one non-mechanical contact sensing element 5 matched with the gear transmission counting mechanism 4 and connected with a data output interface 7 fixedly arranged on the watchcase 2 through a sensing element connecting wire 6. The common water meter 1 with the data output interface 7 is adopted, and can be selected for use according to the actual needs of users. The intelligent water meter can be used independently as a common water meter, and meanwhile, under the conditions of not violating a metering law and not disassembling a meter seal, the intelligent internet of things of the water meter can be realized only by connecting the data output interface with an external intelligent device. After the intelligent water meter is connected with an external intelligent device and a front valve of a remote control meter in a plugging mode, a new intelligent mode water meter is formed. When a component of the external device is damaged, the component is not required to be called an intelligent water meter as in application No. 201910716375.0, once the component is damaged, the seal 13 cannot be opened to repair the internal component according to the regulation of the metering law, and only the whole meter comprising a plurality of control modules can be replaced. And the utility model discloses a water gauge, because the outer connecting part only the grafting mode is connected, need not breach the seal 13 of measurement law regulation to the water gauge body and unseal, only need the maintenance or change external device damage part can, practiced thrift the fortune maintenance cost of enterprise greatly.

And the water meter replacement cycle specified by the metering method is achieved, the meter seal is not disassembled under the condition of not violating the metering method, only the water meter with the data output interface 7 is replaced, and all other external intelligent internet of things devices, IP addresses, control valves and the like can be continuously used, so that the meter replacement cost of water supply enterprises is greatly reduced, and a large amount of social resources are saved.

The conventional water meter 1 may be of a general dry-type water meter structure.

The data output interface 7 is made integral with the case 2, as shown in figure 3, so as to comply with the regulations for the entire table of the metrological law. The data output interface 7 may also be a through hole for the inductive element connection line 6 to pass through.

A socket or a plug or a connecting terminal 7-1 is arranged in the data output interface 7. As shown in fig. 3, the sensing element connection wire 6 is connected to the connection terminal 7-1. By adopting the structure, the data output interface can be provided with various joints such as USB, audio, type-c and the like, and is connected with the Internet of things, the Internet and other various communication systems.

As shown in fig. 2, the water meter with the data output interface further includes a protective cover 14 detachably connected to the data output interface 7, for isolating the data output interface from the outside, so as to perform a dust-proof or moisture-proof function. The protective cover 14 can be detachably connected to the data output interface 7 by a screw connection or a snap connection, and is connected to the data output interface 7 when leaving the factory. If the water meter is used as a common water meter, the protective cover 14 does not need to be detached, so that the water meter can play a dustproof and moistureproof role; if the external intelligent device is needed, the protective cover 14 is removed.

The non-mechanically contacted inductive element 5 may be a magnetic inductive element.

Or, the non-mechanical contact sensing element 5 is a light sensing element, and comprises a light projector 9 and a light receiver 10 which are matched with the rotating component 8 of the gear transmission counting mechanism 4; when the rotating member 8 rotates, the light projected by the light projector 9 can pass through the rotating member 8 and be received by the light receiver 10.

At least one rotating part 8 in the gear transmission counting mechanism 4 is provided with at least one light-transmitting through hole 11 which is arranged between the light projector 9 and the light receiver 10. When the user uses water as shown in fig. 2, the impeller 3 drives the geared counter mechanism 4 to rotate. As shown in fig. 4, the rotating member 8 is provided with a through hole 11, and when the rotating member 8 rotates one turn, the light emitted from the light projector 9 passes through the through hole 11 and is received by the light receiver 10, thereby generating a pulse signal. The photoelectric sensing part is very simple, only a light-transmitting through hole 11 is arranged on a rotating part 8 in the gear transmission counting mechanism 4, and compared with other water meters, such as a high-precision photoelectric direct-reading intelligent meter named as '201020208598.0', the photoelectric sensing part adopts a non-contact sensing element, does not change the structure of the original water meter, and does not influence the mechanical counting precision of the original water meter. And because the water meters are all installed in the water well room, the environment is humid, and the electronic elements are easily influenced and damaged. The electronic component has the advantages of simple structure, low cost and small number of used components, so that the probability of damp failure of the electronic component is reduced, the environmental adaptability is stronger, and the reliability is higher.

Alternatively, the rotating member 8 is a gear plate of the gear-driven counting mechanism 4, as shown in fig. 4. The requirement can be met only by improving the original gear disc of the original common water meter 1, the structure is simpler, and the process requirement is lower. Alternatively, the rotating part 8 is a rotating disc sleeved on the gear transmission counting mechanism 4.

As shown in figure 2, the present application is a new common water meter which accords with the seal regulation of the metering method verification by adding a light sensing element on a rotating part 8 of a gear transmission counting mechanism 4 in the common water meter 1, connecting the light sensing element with a data output interface 7 through a sensing element connecting wire 6, and packaging the light sensing element and the data output interface together when the common water meter leaves a factory. Because the light sensing element is not contacted with the gear disc, when the external intelligent equipment is not connected, the light sensing element can be used as a common water meter, and the precision of a mechanical counting number wheel cannot be influenced; as shown in fig. 5, when the water meter is connected with an external intelligent device, the water meter can be used as an intelligent water meter. When a part of the external equipment is damaged, the regulation of a metering method is not violated, the seal 13 is not required to be disassembled, and only the external equipment is maintained; when the water meter reaches the service life or the internal components of the water meter are damaged, only the whole meter needs to be replaced, and the external intelligent equipment can still be continuously inserted on a new meter for continuous use. By the mode, on the premise of not violating the metering method, the cost of maintaining or replacing the water meter is greatly saved, and the method has great commercial value.

The fixed connection which is not specified can be a connection mode such as riveting, welding, bolt connection and the like, a movable connection can be a connection mode such as hinging and the like.
