Abstract
The utility model relates to a rotor water gauge, in particular to an induction transmitting device arranged on the side surface of an impeller shaft body. The induction transmitting device mainly comprises an impeller and a gear box, wherein a metal damping fin is mounted on the side surface of the shaft body of the impeller; and an inductance coil is mounted in the gear box in the position corresponding to the metal damping fin in the shaft body of the impeller. In the utility model, as both the metal damping fin and the inductance coil are made of nonmagnetic materials, resistance can not be increased to the rotation of the impeller; meanwhile, as the induction transmitting device is arranged on the side surface of the impeller shaft body, clearance for floating upwards is retained when the impeller is driven to rotate by current rush, and the original performance of a water gauge can not be changed; and as the distance between the inductance coil mounted in the gear box and the corresponding metal damping fin mounted in the impeller shaft body remains unchanged, the induction transmitting device can output stable electrical signals.
Description
Technical field
The utility model relates to a kind of rotor water gauge, especially a kind of induction transmitting device that is arranged on the impeller shaft body side surface.
Background technology
Rotor water gauge commonly used mainly is made up of watchcase, impeller metering mechanism, indicating mechanism etc.Wherein, impeller metering mechanism is made up of impeller box and impeller.After current enter water meter, enter impeller box from all directions of watchcase inner chamber bottom; Current are after the inlet opening inflow of impeller box, and drive impeller is rotated on the one hand, and current itself rise twist on the other hand, and discharge from the apopore on impeller box top.The moving mechanical indicating mechanism of the rotating band of impeller counts, and indicates the volume of the water of the water meter of flowing through.
In order to realize the electronization of water meter, during beginning, generally be to repack a certain bit pointer in the water meter indicating mechanism into have magnetic pointer, a reed switch (tongue tube) is installed above the water gage glass of corresponding this magnetic pointer, when the magnetic pointer rotates a circle, reed switch closure under the effect of magnetic once and transfers out a switching signal by circuit and gives receiving trap.This water meter of posting a letter does not possess antimagnetic function, will make reed switch closed always on the reed switch when magnet is placed on, and receiving trap does not just again receive the signal that reed switch transfers out.Like this, the water meter of posting a letter of two reed switchs of three-wire system just occurred, when receiving trap receives that simultaneously two reed switchs transmit next signal, just known the interference that has been subjected to magnetic field, receiving trap will send alerting signal.
In order to solve the interference in magnetic field, the water meter of posting a letter that magnet and two reed switchs is assemblied in water meter indicating mechanism inside is arranged; The water meter of posting a letter that adopts shielding mode reed switch to be played demagnetizing effect is also arranged; And the water meter of posting a letter of non-magnetic inductance type and photo-electric, this is the earliest electric water meter just.Receiving trap is sent to water supply department by various wired or wireless modes with water yield signal with the signal that receives, and has constituted the remote copying system of water meter.
For the interference of eliminating magnetic field with the accuracy that improves signal and make the rotary wind type electronic water meter, usually water meter inner with the corresponding gear of pointer on or the induction transmitting device is set on the impeller, main indicating value or its variable quantity of mechanical type water meter is transformed into electric signal or other signal.
The induction transmitting device of non-magnetic inductance type is set on impeller, normally on the top of impeller axis body the metal damping fin is set, position corresponding in gearcase is provided with inductance, when current promote wheel rotation its variable quantity is transformed into electric signal and exports.
Because current are after the inlet opening inflow of impeller box, drive impeller rotation on the one hand, current itself rise twist on the other hand, and make impeller produce floating upwards, thereby the metal damping fin that impeller axis body top is provided with has produced variation with the distance that is arranged on the inductance of correspondence position in the gearcase, and then Shu Chu electric signal produces strong and weak variation along with the variation of current, even do not have signal, influence the operate as normal of receiving trap.If keep the distance of the inductance that metal damping fin that impeller axis body top is provided with and correspondence position in gearcase be provided with constant, and the top and the bottom of impeller are withstood, make impeller water impact promote rotatablely move in not have upwards unsteady gap, then can have a strong impact on the performance of water meter.Load and respond to original performance that transmitting device must not change water meter, must guarantee to respond to the signal stabilization of transmitting device output again.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned weak point, thereby a kind of induction transmitting device that is arranged on the impeller shaft body side surface is provided, and this induction transmitting device does not change original performance of water meter, can guarantee the stable electric signal of induction transmitting device output.
The technical scheme that provides according to the utility model, a kind of induction transmitting device that is arranged on the impeller shaft body side surface comprises impeller and gearcase, the metal damping fin is installed in the side of the axis body of described impeller, telefault be installed in the gearcase with the axis body that is installed in impeller in the corresponding position of metal damping fin.
Compared with the prior art the utility model has the following advantages:
The utility model is simple, compact and reasonable for structure; Because metal damping fin and inductance are non-magnetic material, so can be to the increase resistance that rotatablely moves of impeller; Simultaneously because the induction transmitting device is arranged on the side of impeller axis body, so impeller water impact promote rotatablely move in still maintain the gap of upwards floating, then can not change original performance of water meter.Because the inductance and the corresponding distance that is installed in the metal damping fin in the impeller axis body that are installed in the gearcase remain unchanged, so, the stable electric signal of induction transmitting device output can be guaranteed.

Fig. 2 is the vertical view of Fig. 1.
Embodiment
Embodiment during following the utility model is incited somebody to action in conjunction with the accompanying drawings is further described:
As shown in Figure 1, comprise impeller 1, metal damping fin 2, telefault 3 and gearcase 4.
The utility model metal damping fin 2 is installed in the side of the axis body of impeller 1, telefault 3 be installed in the gearcase 4 with the axis body that is installed in impeller 2 in the corresponding position of metal damping fin.
Principle of work of the present utility model: water impact promotes impeller 1 and rotatablely moves, and the telefault 3 that is installed in the gearcase 4 is exported induction current being installed under the effect of the metal damping fin 2 in the axis body of impeller 1 with corresponding position.
Because metal damping fin 2 is respectively non-magnetic material with telefault 3 and makes, so can be to the increase resistance that rotatablely moves of impeller 1; Simultaneously, impeller 1 still maintains the gap of upwards floating in rotatablely moving, so can not change original performance of water meter.Remain unchanged owing to be installed in the distance of the metal damping fin 2 in telefault 3 and the corresponding axis body that is installed in impeller 1 in the gearcase 4, so, can guarantee to respond to transmitting device and export stable electric signal.
