Abstract

The utility model relates to a nonmagnetic direct-reading electronic remote transmitting water meter. In the utility model, two microswitches are fixedly installed on a supporting plate in an opposite way, a star gear is arranged between the two microswitches, and the star gear is connected with the two microswitches in a point-contact way; the structure that the star gear is coaxially connected with a *0.1m < 3 > gear of a gear set between the supporting plate and a lower clamping plate solves the defect that a similar water meter of the prior art can not identify and read the states of the positive and the reverse rotation of a water meter. The data of the mechanical counting are completely the same as the data of an electronic signaling; mechanical signals of the positive and the reverse rotation of the water meter can be converted to electrical signals which are arranged in a circulating way to output by utilizing the combining mode of the two microswitches and a mechanical counting gear, the positive and the reverse rotation and the read numbers of the water meter can be distinguished; meanwhile, the utility model is free from magnetic field interference, the inside l power consumption is small and the power consumption does not exist when the water meter is not read outside. The utility model has the advantages that the structure is simple and small, the operation is stable and reliable, the production process is good and the cost is low.

Description

Non-magnetic Direct Reading Electronic Long-distance Transferring Water-meter

Technical field

The utility model relates to a kind of Non-magnetic Direct Reading Electronic Long-distance Transferring Water-meter, belongs to the flow metering field.

Background technology

Before the present utility model, existing most of direct reading remote watermeters are to adopt many group potentiometers or photoelectric tube to produce water meter as senser element, this sensor of water meter spare just just carries out the work of the similar formula of taking pictures when checking meter, so can not distinguish the water meter positive-negative rotation state, processing and the assembly precision of device too many (20 pairs of sensors are arranged usually) to part requires height, production technology is difficult, production cost is high, operational failure rate height, is unsuitable for being used for producing domestic water meter owing to passing.

Summary of the invention

The purpose of this utility model just is to overcome above-mentioned defective, designs a kind of pair of microswitch mixed internal processor as signal transmitter whole Non-magnetic Direct Reading Electronic Long-distance Transferring Water-meter.

The technical solution of the utility model is:

Non-magnetic Direct Reading Electronic Long-distance Transferring Water-meter, its major technique are characterised in that and fixedly install two microswitches on supporting plates, are provided with in opposite directions, and the centre is a spider gear, and the some contact connects, the gear set between spider gear and supporting plate, the lower plate * 0.1M ³The coaxial connection of position gear.

The utility model not only has the direct-reading water meter advantage, and the data consistent of mechanical count and electronics sender.The mode of utilizing two microswitches to combine with the gear of mechanical count is converted to the mechanical signal of water meter forward and backward the electric signal output of cycle arrangement, can differentiate water meter rotating and reading thereof, simultaneously be not subjected to magnetic interference again, internal power consumption is minimum, does not have power consumption when do not check meter in the outside.The utility model is simple in structure, small and exquisite, working stability, reliable, and production technology is good, cost is low.

Embodiment

As Fig. 1, Fig. 2, Fig. 3, shown in Figure 4, water meter lower plate 1 top is gear set, comprises gear 3,4,5,6,7,8,9,10 and 11; Lower plate 1 bottom is that supporting plate 2 is downwards watchcase 17 again, fixedly connected two microswitches on supporting plate 2, left side microswitch 14, right microswitch 12, spider gear 13 is set in the middle of two microswitches, it is connected with two microswitch point contacts respectively and successively, promptly is connected with the moving contact contact of microswitch; The gear 11 (* 0.1M of the gear set on spider gear 13 and the lower plate 1 ³The position) coaxial connection.Supporting plate 2 tops also are provided with circuit board 15, lithium battery 16.

When the water meter water metering, (* 0.1M ³When the position) gear 11 rotation drive spider gears 13 clockwise rotate, the right microswitch 12 normally closed disconnection that often switches on earlier, the left microswitch 14 in back often switches on-normally closed disconnection, sender successively circulates, it circulates successively for ab (contact a, b connect) → ac → de → df------in proper order, and this sender mode can be made as is just changeing counting; When counterclockwise running (counter-rotating counting), it circulates successively for df → de → ac → ab------in proper order.Like this, mechanical reading can be in full accord with electronical reading, and have the function that enough prevents improper use water meter, promptly eliminates the certain user and utilize forward and backward to make water meter disregard the behavior of reading or few reading.Exactly because also this reason, when a switch breaks down when having only a microswitch operate as normal, receiving end can convert single microswitch count status automatically to, then can normally count in the same old way, and consistent with mechanical count, just there is not the counter-rotating recognition function.

Utilize spider gear 13 alternating actions left side microswitch 14, right microswitch 12, make its rotational resistance torque minimum, also minimum to the influence of water meter measurement degree of accuracy.

The switching value pulse signal that microswitch 12,14 (as the sender assembly) sends is sent to the electronic processors in the circuit board 15, behind accumulating operation, refresh and be stored in the storer, when need the copy reading water meter, by two heart yearns 18 from communication interface by directly reading digital signals such as water consumption in the storer.

Protection domain of the present utility model is not limited only to the description of this embodiment.
