Detailed Implementation

[0028] To make the objectives, features, and advantages of this invention more apparent and understandable, the technical solutions of the embodiments of this invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this invention, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this invention without creative effort are within the scope of protection of this invention.

[0029] See Figures 1 to 8 As shown, an embodiment of the present invention provides a jet water meter, comprising:

[0030] The water meter housing 10 has a jet oscillation cavity 105 inside. The water meter housing 10 also has a jet inlet 103 and a jet outlet 102. The jet inlet 103 is connected to one side of the jet oscillation cavity 105, and the jet outlet 102 is connected to the other side of the jet oscillation cavity 105.

[0031] A turbine housing 50 is provided with an accommodating space 501 in the interior of the turbine housing 50, the accommodating space 501 is communicated with the jet flow inlet 103, and the turbine housing 50 is provided with a water inlet 502 on the side away from the jet flow inlet 103, the water inlet 502 is communicated with the accommodating space 501, and the disturbing turbine 40 is rotatably arranged in the accommodating space 501 so that the disturbing turbine 40 can rotate relative to the central axis.

[0032] The jet flow water meter provided by the embodiment comprises a water meter housing 10 and a turbine housing 50, the interior of the water meter housing 10 is provided with a jet flow oscillation cavity 105, the water meter housing 10 is further provided with a jet flow inlet 103 and a jet flow outlet 102, the jet flow inlet 103 is communicated with one side of the jet flow oscillation cavity 105, the jet flow outlet 102 is communicated with the other side of the jet flow oscillation cavity 105, the accommodating space 501 is communicated with the jet flow inlet 103, the turbine housing 50 is provided with a water inlet 502 on the side away from the jet flow inlet 103, the water inlet 502 is communicated with the accommodating space 501, and the disturbing turbine 40 is rotatably arranged in the accommodating space 501. When the jet flow water meter in the embodiment works, the water flow enters the accommodating space 501 through the water inlet 502, then enters the jet flow oscillation cavity 105 through the jet flow inlet 103, and then flows out through the jet flow outlet 102. The water flow oscillates in the jet flow oscillation cavity 105, and the flow measurement is completed based on the electromagnetic principle that the water flow oscillation cuts the magnetic field. Since the water flow cannot oscillate when it enters the jet flow oscillation cavity 105 through the jet flow inlet 103 when the flow is small, the flow cannot be measured when the flow is small. In the embodiment, the rotation of the disturbing turbine 40 generates turbulence when the flow is small, so that the water flow in the jet flow oscillation cavity 105 can break the laminar flow at a smaller flow point and oscillate, thereby realizing the expansion of the flow measurement range, and the flow measurement can be performed under the condition of small flow.

[0033] In the embodiment, the turbine housing 50 and the water meter housing 10 are integrally formed, which can not only improve the strength of the entire housing, but also simplify the production and processing process. In addition, the disturbing turbine 40 in the embodiment can adopt any turbine structure in the prior art, which is rotatably arranged through a rotating shaft, and the rotating shaft can be connected with the inner wall of the turbine housing 50. Specifically, a support (not shown in the figure) can be arranged on the inner wall, and the rotating shaft is rotatably installed on the support.

[0034] In addition, the disturbing turbine 40 in the embodiment can be arranged at the central position of the accommodating space 501.

[0035] Further, the oscillation cavity 105 in the embodiment is generally provided with two oscillation wall components 20, which are symmetrically arranged with the jet inlet 103 as the center, and the water flow enters the space between the two oscillation wall components 20 after passing through the jet inlet 103. The two oscillation wall components 20 are arranged obliquely, so that the space between the two oscillation wall components 20 has a smaller size at one end and a larger size at the other end. Specifically, the space between the two oscillation wall components 20 close to the jet inlet 103 is smaller than the space between the two oscillation wall components 20 close to the jet outlet 102. In addition, the outer side of the oscillation wall component 20 is an arc surface, and the inner walls of the two sides of the oscillation cavity 105 are arc surfaces. The outer side surface of the oscillation wall component 20 and the inner wall of the oscillation cavity 105 form a backflow channel 101. In addition, a flow dividing component 30 is arranged between the two oscillation wall components 20. The internal structure of the oscillation wall component 20, the flow dividing component 30, the backflow channel 101 and the oscillation cavity 105 in the embodiment can facilitate the oscillation of the water flow in the oscillation cavity 105. The upper part of the water meter shell 10 in the embodiment is provided with a magnetic induction assembly 100. The oscillation of the water flow in the oscillation cavity 105 will cause the change of the cutting magnetic induction line. The magnetic induction assembly 100 can obtain the oscillation frequency based on the change of the cutting magnetic induction line, and the flow rate can be calculated based on the oscillation frequency.

[0036] In a further implementable manner of the embodiment, the jet water meter further comprises a turbine induction unit 60 and a turbine metering unit (not shown in the figure). The turbine induction unit 60 is arranged correspondingly to the turbulence turbine 40 for inducing the rotating speed of the turbulence turbine 40. The turbine metering unit is used to calculate the flow rate of the water flow passing through the containing space 501 based on the rotating speed of the turbulence turbine 40.

[0037] In the embodiment, the flow rate of the water flow can be obtained by obtaining the rotating speed of the turbulence turbine 40. Based on the flow rate, the magnetic induction assembly 100 can be compared and calibrated to improve the accuracy of the jet water meter and prevent large errors.

[0038] Specifically, the turbine induction unit 60 in the embodiment is a non-magnetic sensor. When the turbine metal blade sweeps, the sensor will emit a pulse, thereby realizing the metering of the rotating speed of the turbine. Corresponding to the flow metering, the non-magnetic sensor in the embodiment can be embedded on the turbine shell 50, and the non-magnetic sensor is arranged towards the turbulence turbine 40.

[0039] In a further implementable manner of the embodiment, the turbulence turbine 40 is provided with a magnetic steel 80, and the jet water meter further comprises an induction coil 70. The induction coil 70 is arranged correspondingly to the magnetic steel 80. In the rotating state of the turbulence turbine 40, the induction coil 70 can generate an induced current.

[0040] The embodiment can generate electricity when the spoiler turbine 40 rotates, which can provide energy for each component of the fluidic water meter, especially in the case of offline measurement, which can provide electricity for it, thereby achieving energy saving effect. The arrangement of the induction coil 70 and the magnetic steel 80 in the embodiment only affects the water pressure, but does not affect the flow of the water meter.

[0041] Specifically, the magnetic steel 80 is added to the spoiler turbine 40, and the induction coil 70 is added to the turbine shell 50 corresponding to the magnetic steel 80. When the magnetic steel 80 on the blade sweeps the induction coil 70, the induction coil 70 generates current, thereby providing a part of the electricity for the fluidic water meter. The magnetic steel 80 in the embodiment is a strong magnetic steel.

[0042] In a further implementable manner of the embodiment, the upper part of the fluidic oscillation cavity 105 is provided with an upper magnetic shielding sheet 90.

[0043] In the embodiment, the upper part of the fluidic oscillation cavity 105 is provided with the upper magnetic shielding sheet 90, which can protect the magnetic field inside the fluidic oscillation cavity 105 and avoid the interference of the external strong magnetic field on the magnetic field inside the fluidic oscillation cavity 105.

[0044] Specifically, the upper magnetic shielding sheet 90 in the embodiment is provided with a mounting opening 901, and the magnetic induction assembly 100 is mounted in the mounting opening 901. In addition, the upper part of the water meter shell 10 in the embodiment is provided with an upper end opening 104, and the upper magnetic shielding sheet 90 is mounted in the upper end opening 104 and closes the upper end opening 104. Specifically, the upper end opening 104 in the embodiment can be a stepped hole.

[0045] In a further implementable manner of the embodiment, the lower part of the fluidic oscillation cavity 105 is provided with a lower magnetic shielding sheet.

[0046] The lower magnetic shielding sheet in the embodiment can protect the magnetic field inside the fluidic oscillation cavity 105 and avoid the interference of the external strong magnetic field on the magnetic field inside the fluidic oscillation cavity 105.

[0048] In use, one of the first adjustment component 110 and the second adjustment component 120 can be installed in the water meter housing 10. Since the volume of the first protruding portion 1102 is smaller than that of the second protruding portion 1202, the first adjustment component 110 and the second adjustment component 120 can be selected for use according to different measurement environments to change the space of the fluidic oscillation cavity 105. The fluid oscillation frequency and the minimum flow rate of the fluidic water meter can be adjusted by adjusting the size of the oscillation cavity. Specifically, since the volume of the first protruding portion 1102 is smaller than that of the second protruding portion 1202, when the first protruding portion 1102 extends into the fluidic oscillation cavity 105, the space occupied by the first protruding portion 1102 is smaller, and the oscillation space inside the fluidic oscillation cavity 105 is relatively larger.

[0049] In a further implementation manner of the present embodiment, the cross sections of the first protruding portion 1102 and the second protruding portion 1202 are the same as the cross section of the fluidic oscillation cavity 105. The first protruding portion 1102 and the second protruding portion 1202 can extend into the fluidic oscillation cavity 105 from the lower opening 106 of the water meter housing 10. The height of the first protruding portion 1102 is lower than that of the second protruding portion 1202.

[0050] In the present embodiment, the cross sections of the first protruding portion 1102 and the second protruding portion 1202 are the same as the cross section of the fluidic oscillation cavity 105. Therefore, the first protruding portion 1102 and the second protruding portion 1202 not only ensure the sealing of the fluidic oscillation cavity 105, but also prevent the fluidic oscillation cavity 105 from being affected in the whole shape, which is more conducive to ensuring the stability of oscillation.
