Description
Technical field
The utility model relates to the sensing device that is used for remote transmitting water meter, is specifically related to a kind of two body water meter pulse sensing device of sending out.
Background technology
In the prior art, in order to solve copying privately of remote transmitting water meter, usually utilize tongue tube to be transformed into " magnetron " of dual-magnetic head self-sustaining mode, can solve the problem of water hammer of remote transmitting water meter substantially, but the transmission of remote transmitting water meter pulse signal is a very complicated problems, this " magnetron " can not solve the interference on the transmission line, can not overcome the mistake that water pipe epistasis vibration brings and send out pulse.As Chinese patent 99219172.6 disclosed " a kind of magnet controlled sensor of water meter ", though solved the error that remote transmitting water meter produces because of the critical swing (water hammer) of induction point, also played effect at self-hold circuit and double-head arrow aspect the anti-magnetic interference, aspect applicability, it has become one to be convenient to the sensor chip installing, change, debug sensor design, can be used for not having wheel dry type, wet type, rotor, spiral shell wing water meter, do not influence simultaneously watch core and take out check and correction, but it still is unresolved epistasis vibration and burst transmissions problem.
The utility model content
At the prior art above shortcomings, the purpose of this utility model is to provide a kind of two body water meter pulse transducers of sending out that overcome epistasis vibration and burst transmissions interference, solve the accuracy problem that the water meter pulse is posted a letter and gathered, to reach the pin-point accuracy of pulsed remote transmitting water meter.
The purpose of this utility model is achieved in that two body water meter pulse sensing devices of sending out, and comprises being located at the rotating disk pointer in the water gauge body and being located at the interior self-retaining magnetron of cage; Described self-retaining magnetron is two, is located at by support and cage on the sight glass of water meter; In two adjacent teeth position of wheels of water meter, it is on two double-head arrow diametrical position of 10 times that number of turns is rotated in its metering, and the magnet of two opposed polarities with the N utmost point and S utmost point is set; The self-retaining magnetron is positioned at the top of described double-head arrow and an end of corresponding up and down two double-head arrows of difference.The self-retaining magnetron is the tongue tube that is provided with opposed polarity magnet.
The utility model is made a two water meter sensing device of sending out bodies with two complete dual-magnetic head pointers and two self-retaining magnetrons, use two adjacent gear positions, and its metering rotation number of turns is that 10 relation is made.Be installed on the position of 0.001t as I group double-head arrow, just then II organizes the position that double-head arrow is installed in 0.01t.Like this, because the randomness of any extraneous interference has determined the abnormal pulsers signal that they all can't make two magnetrons send to satisfy 10 times carry relation, have only water meter when normal gage work, to drive I, II group double-head arrow and rotate that just can to satisfy adjacent two be 10 times carry relation, thereby solved the accurate transmission problem that the remote transmitting water meter pulse is posted a letter effectively by gear drive.Overcome the epistasis vibration and disturbed, solved the accuracy problem that the water meter pulse is posted a letter and gathered, reached the pin-point accuracy of pulsed remote transmitting water meter with burst transmissions.The utility model also has reasonable in design, simple in structure; The advantage of reliability, good stability.
Description of drawings
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is a vertical view of the present utility model.
Embodiment
Referring to Fig. 1, Fig. 2, the two body water meter pulse sensing devices of sending out of the utility model comprise rotating disk pointer of being located in the water gauge body 13 and the self-retaining magnetron of being located in the cage 56; Described self-retaining magnetron 6 is two, is located at by support 7 and cage 5 on the sight glass 2 of water meter; In two adjacent teeth position of wheels of water meter, it is the magnet 4 that two opposed polarities with the N utmost point and S utmost point are set on two double-head arrow 3 diametrical position of 10 times that number of turns is rotated in its metering; Two self-retaining magnetrons 6 are positioned at the top of described double-head arrow 3 and an end of corresponding up and down two double-head arrows of difference.Described self-retaining magnetron 6 is for being provided with the tongue tube of opposed polarity magnet.8 is signal transmssion lines among Fig. 2.
Generally speaking, two self-retaining magnetrons are in the time spent of doing that is subjected to magnetic field force, and two contact is contact just, and magnetic field force is not responded to and when acting on thereon, two contacts disconnect at once.Corresponding double-head arrow in two corresponding water gauge bodies of self-retaining magnetron difference, when the N utmost point of the sense contact of self-retaining magnetron and respective pointer or the S utmost point are had an effect, the automatic maintenance function that just has conducting or off-state, if when promptly not having external induction, the self-retaining magnetron should keep its conducting or off-state always.At this moment, if two double-head arrows of water meter rotate, then the magnet on it also rotates thereupon together, during magnet induction end under the magnet on the pointer goes to the self-retaining magnetron, because it is identical with polarity on the pointer that this end attachment magnets is the S utmost point, thereby repelled, the contact disconnects, after the utmost point transfers, and the maintenance effect that the self-retaining magnetron of this moment has attachment magnets, its contact still keeps off-state, when this process goes to induction end up to the N of the pointer utmost point, inhale mutually, make the contact conducting of self-retaining magnetron with the S utmost point of induction end, after the N utmost point is rotated further and leaves, the contact still keeps conducting, and when the next S utmost point went back to again, the contact disconnected again, going round and beginning again successively forms continuous induced signal, through transmission line.Like this, the self-retaining magnetron only could realize when two double-head arrows are responded to simultaneously that one logical one is disconnected, thereby the self-sustaining magnetron of using the band double-head arrow has effectively solved problem of water hammer; Epistasis vibration and burst transmissions problem have been solved simultaneously.The effect of radome is the interference that is used to prevent external magnetic field.
This sensing device adopts three-way transmission, requires software to do corresponding programming simultaneously, and non-innovative point of the present utility model is not described in further detail at this.General essentic-water-meter dial plate has only φ 77, φ 82,101 3 sizes of φ, thereby only need make three kinds of different sizes two send out the demand that body water meter sensing devices almost just can satisfy whole common water meters, structurally do corresponding change and also can be used for volumetric water meter.
The self-sustaining magnetron that this sensing device is used the band double-head arrow has solved problem of water hammer; Use two bodies of sending out and solved epistasis vibration and burst transmissions problem; The utilization self-supporting switch makes two body water meter pulse transducers of sending out, and effectively solves the accuracy problems of copying privately of remote transmitting water meter.
