In some embodiments, referring to fig. 1, a non-magnetic flow meter device of the present application comprises: the fluid detection device comprises a rotating assembly 110, a reflecting assembly 120 and a detecting assembly 130, wherein the rotating assembly 110 is driven by a fluid to be detected to rotate, the reflecting assembly 120 is connected with the rotating assembly 110, the rotating assembly 110 is used for driving the reflecting assembly 120 to rotate when rotating, the detecting assembly 130 comprises a first detecting unit 131 and a second detecting unit 132, the first detecting unit 131 is used for transmitting a first initial optical signal to a first position of the reflecting assembly 120 and receiving a first target optical signal reflected by the first position, and the second detecting unit 132 is used for transmitting a second initial optical signal to a second position of the reflecting assembly 120 and detecting a second target optical signal reflected by the second position.
In the exemplary embodiment, one end of the rotating assembly 110 is connected to an impeller (not shown in the figure), the impeller is disposed between the liquid inlet and the liquid outlet of the flow metering device, and when the fluid to be measured flows, the impeller is driven by the fluid to rotate, so as to drive the rotating assembly 110 to rotate. The other end of the rotating component 110 is connected to the reflecting component 120, and when the rotating component 110 rotates, the reflecting component 120 is correspondingly driven to rotate at the same time. The rotating component 110 and the reflecting component 120 may be rigidly connected, or may be connected to each other by providing a gear structure, and only the rotation of the rotating component 110 needs to be transmitted to the reflecting component 120. In some other embodiments, the rotating assembly 110 may be coupled to any rotating device that uses the principle of rotation to sense flow, such as a blade, a turbine, or other rotating mechanism.
The reflection assembly 120 is disposed parallel to the detection assembly 130, the detection assembly 130 is disposed with a first detection unit 131 and a second detection unit 132, which are used to send a first initial optical signal and a second initial optical signal to different positions, i.e., a first position and a second position, of the reflection assembly 120, when the first initial optical signal and the second initial optical signal irradiate on the reflection area of the reflection assembly 120, respectively, the reflection assembly 120 will reflect the optical signals to form a first target optical signal and a second target optical signal, respectively, so that the detection assembly 130 detects the optical signals, and since the positions and times of the first detection unit 131 and the second detection unit 132 that detect the reflected optical signals will generate differences, the flow direction of the fluid can be determined while the flow rate of the fluid is detected.
The flow detection principle of the present application is described in detail below with a specific embodiment. Referring to fig. 2, the reflective member 120 is composed of a reflective region 121 and a non-reflective region 122, the reflective region 121 equally divides the reflective member 120 from the non-reflective region 122, a first target optical signal detected by the first detecting unit 131 is emitted from a 90 ° position of the reflective member 120, a second target optical signal detected by the second detecting unit 132 is emitted from a 0 ° position of the reflective member 120, and positions of the first initial optical signal and the second initial optical signal irradiated onto the reflective member 120 are maintained unchanged without changing with rotation of the reflective member 120. By the rotation of the reflection assembly 120, the light intensities of the first target light signal and the second target light signal detected by the first detection unit 131 and the second detection unit 132 are continuously changed, thereby obtaining a changed logic level signal. Referring to fig. 3, a is a diagram of the logic levels detected by the first detecting unit 131, B is a diagram of the logic levels detected by the second detecting unit 132, the logic levels of the diagram are determined by the intensity of the reflected light signal, the intensity of the light signal reflected by the reflective area 121 is high, the logic levels are high, the light signal detected by the non-reflective area 122 is weak, and the logic levels are low. When the reflection assembly 120 rotates counterclockwise, when the rotation angle is 0 °, the first detection unit 131 and the second detection unit 132 both detect a bottom level; when the rotation angle is 90 °, the first detecting unit 131 detects the optical signal reflected by the reflective area 121, the logic level changes to high level, and the second detecting unit 132 remains in the non-reflective area and is also low level; when the rotation angle is 180 °, the first detecting unit 131 remains in the reflective region and is at a high level, the second detecting unit 132 detects the optical signal reflected by the reflective region 121, and the logic level changes to a high level; when the rotation angle is 270 °, the first detecting unit 131 detects the optical signal reflected by the non-reflective region 122, the logic level changes to a low level, and the second detecting unit 132 remains in the reflective region and is still at a high level; when the rotation angle is 360 °, the same rotation angle as when the rotation angle is 0 ° is not described in detail here. The number of rotations of the reflection assembly 120 can be detected by the logic level signals detected by the first detection unit 131 and the second detection unit 132, so that the flow rate can be calculated according to a specific design structure, and the rotation direction of the reflection assembly 120 can be obtained according to the phase relationship between the waveform A and the waveform B, so that the flow direction of the fluid can be obtained.
In some embodiments, the first detection unit 131 and the second detection unit 132 each include a transmission interface and a reception interface. In order to facilitate the structural design, the existing detection unit with the functions of sending and receiving optical signals is adopted, and the modular design is facilitated. In some other embodiments, separate transmitting units and receiving units can be selected to achieve the same technical effect.
In some embodiments, the emission interface of the first detection unit 131 and the emission interface of the second detection unit 132 both emit ultraviolet light. In some other embodiments, the transmission interface may also be caused to emit infrared light.
In some embodiments, the reflective element 120 includes a reflective region for reflecting the first target optical signal according to the first initial optical signal, a reflective region for reflecting the second target optical signal according to the second initial optical signal, and an absorptive region for absorbing the first initial optical signal and the second initial optical signal. The surface of the reflecting area is provided with a reflecting material for reflecting light signals to the maximum, and the absorbing area is set to be black or provided with a light absorbing material for reducing the reflection phenomenon of light waves to the maximum and ensuring the stability of the detection environment.
In some embodiments, the reflective region is disposed axisymmetrically with respect to the absorptive region. The reflective region can be arbitrarily divided into 1/2, 1/4, 1/8, etc. of the reflective element 120, and the absorption regions are axially symmetric with respect to the reflective region, so as to facilitate processing of the detected logic level signal.
In some embodiments, the reflective element 120 includes a reflective region for reflecting a first target optical signal according to a first initial optical signal, a reflective region for reflecting a second target optical signal according to a second initial optical signal, and a transmissive region for transmitting the first initial optical signal and the second initial optical signal. The non-reflective region of the reflective element 120 may also be a transmissive region, and the optical signal directly passes through the transmissive region without generating a reflective optical signal, which may achieve the same technical effect.
In some embodiments, the transmissive region is a via. The non-reflective region 122 of the reflective member 120 is configured as a through hole, so that the volume of the reflective member 120 is reduced and no reflected optical signal is generated.
In some embodiments, the reflective member 120 is configured in a circular shape. The arrangement is circular to facilitate rotation of the reflective member 120, and in some other embodiments, may be rectangular, circular, or other patterns.
In some embodiments, a non-magnetic flow measuring device of the present application further includes a processor, where the processor is connected to the detecting component 130, and the processor is configured to process the optical signal reflected by the reflecting component 120 and calculate the flow rate of the fluid to be measured. Referring to fig. 4, the processor includes a signal detection module for detecting the logic level signal collected by the detection unit; the power management module can control whether the detection unit works or not, and control whether the detection unit emits and detects optical signals or not; the RTC clock module is used for providing a clock signal required by the flow metering device; the pulse signal output is used for outputting a pulse signal to the power management module; the communication interface is used for being connected with other functional modules and sending the flow calculation result of the fluid to be measured calculated by the processor.
