For a more clear understanding of the technical features, objects and effects of the present invention, embodiments of the present invention will now be described in detail with reference to the accompanying drawings.
Fig. 1 and 2 illustrate an intelligent liquid flow detection device in some embodiments of the invention, which is used for detecting the flow state of the liquid to be detected in the pipe 60 to be detected through the detection body 20 and generating the sensing data. The device for detecting the flowing state of the liquid in the tube in the embodiment comprises a detection body 20, a centering assembly 40, a sensing unit 10, a main control unit 30, a memory unit 50, a signal transceiving unit 70, an energy providing device 90 and a liquid flow control device 100, wherein the detection body 20 is a rod-shaped object and is used for detecting the flowing state of the liquid to be detected in the tube 60 to be detected; the aligning component 40 is used for aligning the detecting body 20 to the central position when the liquid in the tube 60 to be detected is static or vacant; the sensing unit 10 is used for sensing the inclined state of the detection end 21 of the detection body 20 under the pushing of the liquid and generating sensing data; the main control unit 30 is used for calculating current liquid flow state data according to the sensing data; the memory unit is used for providing a corresponding table or a calculation formula of the sensor data inclination angle and the flow rate to the main control unit 30; the signal transceiving unit 70 is for transmitting the flow state data to the outside; the energy supply device 90 is used for supplying power to other components by using external wireless energy or wired energy such as solar energy, vibration energy and the like; the liquid flow control device 100 is used to control the flow of liquid.
The detecting body 20 is a rod-shaped object, one end of which is a detecting end 21, and the other end is a free end 22. The detection end 21 is disposed inside the tube 60 to be measured and contacts the liquid to be measured, and the free end 22 is disposed outside the tube 60 to be measured.
The aligning component 40 is disposed on the detecting body 20, and the aligning component 40 is used for pulling and/or pushing the free end 22 and/or the detecting end 21 under the state that the liquid to be detected is static or the water pipe to be detected is empty, so as to align the detecting body 20 to the central position state. It will be appreciated that in some embodiments, the central position state is a vertical state. Alternatively, the form of the correcting element 40 may be various, and is not particularly limited as long as the related function can be achieved.
In some preferred embodiments, the centering assembly 40 includes a fixed member 41 and an elastic member 42. The fixing member 41 is fixedly disposed on the external fixing end, and it is understood that the external fixing end may be a bottom surface or other fixing position located outside the detecting device, so that the fulcrum of the detecting body 20 is outside the tube to be detected and can be effectively fixed. The elastic member 42 has a certain elasticity and is elastically and telescopically coupled between the fixed member 41 and the free end 22 or between the fixed member 41 and the detection end 21. When the liquid to be measured is still or the water pipe to be measured is empty, the elastic member 42 reaches elastic force balance, and elastically contracts to return the detecting body 20 to the right through the detecting end 21 or the free end 22. Preferably, the elastic member 42 is a spring and/or an elastic silicone rubber, or an elastic substance, which may be a solid, liquid or paste-like substance having elasticity and keeping the detection body 20 back to the positive state without any other external force.
In other preferred embodiments, the detection body 20 further includes a T-shaped pipe, the T-shaped pipe is disposed on the free end 22, and both ends of the T-shaped pipe are respectively connected to the aligning member 40. The T-shaped pipe is a water pipe, and the pipe type comprises a through pipe, a T-shaped pipe, a cross-shaped pipe, a multi-channel pipe and the like. Accordingly, the aligning member 40 includes two fixing members 41 and two elastic members 42, the two fixing members 41 are respectively fixed at two positions of the outer fixing end, and the two elastic members 42 are respectively connected to two ends or the inside of the T-shaped pipe. This has the advantage that the test body 20 can be connected to the elastic member 42 through both ends of the T-shape of the T-shaped pipe, thereby making the connection easier and more secure.
As shown in fig. 2, the sensing unit 10 is disposed at a free end 22 (not shown in fig. 1) of the detection body 20, and the sensing unit 10 is configured to sense an inclined state of the detection body 20 at the detection end 21 under the pushing of the liquid and generate sensing data. Alternatively, the sensing unit 10 is a very lightweight micro-electromechanical sensor. The sensing data includes the inclination direction and the inclination angle of the detection tip 21. In some embodiments, the sensing unit 10 includes at least one axis acceleration sensor for sensing the inclination direction and the inclination angle of the detection end 21. Alternatively, the sensing unit 10 is one or more of an acceleration, a gyroscope, and a geomagnetic sensor.
The main control unit 30 is connected to the sensing unit 10, and is configured to calculate current liquid flow state data according to the sensing data. Wherein the flow state data comprises the current liquid flow direction and flow speed. Alternatively, the main control unit 30 may be an MCU, a chip, an electronic circuit, etc., and is not limited herein as long as the related functions can be realized.
The memory unit 50 is connected to the main control unit 30, and provides a corresponding table or calculation formula of the inclination angle and the flow rate of the sensor data, so as to be called by the main control unit 30. It should be noted here that, in the table corresponding to the inclination angle and the flow rate of the sensor data in the storage unit 50, in order to test data such as the relation between the inclination angle of the detection body 20 and the water flow and the water pressure through a laboratory, the main control unit 30 reversely queries the water flow and water pressure data according to the posture of the detection body 20 in an actual test to obtain the current liquid flowing state data, thereby achieving the test purpose. Because the water pressure of the water flow on the detection body 20 is in a certain relation with the centering force of the spring, the range which can be measured by the detection body 20 is different flow rates in all strokes when the detection body 20 is centered to be completely deflected, the flow direction can be identified only by deflecting to one side, and the key point is that the flow rate is continuous data and more data are needed to correspond to the flow rate.
The signal transceiving unit 70 is connected to the main control unit 30, and the signal transceiving unit 70 is used to transmit the flow state data to the outside. Alternatively, the signal transmission form of the signal transceiving unit 70 includes wired or wireless. Preferably, the signal transceiver unit 70 may be in a wireless communication mode such as WiFi, bluetooth, infrared, ZigBee, and the like, and is not particularly limited herein as long as the related functions can be implemented.

In some embodiments, the energy supply device 90 may or may not be provided, and when not provided, other power supply devices may be used instead, as long as the related functions can be achieved. The energy supply device 90 has the advantages that because most of the detection devices are installed in hidden places in the embodiment of the invention, the acquisition of electric power is a great problem, so that the energy collection system collects energy through electric waves or light (light or solar energy), and meanwhile, the ultra-low power consumption design is adopted, the data transmission times and transmission conditions of the electric waves are limited, and the equipment can work for more than several years. Further, if the power balance cannot be achieved or the power is insufficient due to a problem of the battery life, the relevant information is also transmitted from the signal transmitting/receiving unit 70.
Liquid flow control device 100 may be placed on the tube 60 to be tested according to the requirements of a particular application. The liquid flow control device 100 controls the flow of the liquid in accordance with the control command received by the signal transceiver unit 70. Specifically, when the control command requires an increase in the liquid flow rate, the liquid flow rate control device 100 amplifies the liquid flow rate; when the control command requires a decrease in liquid flow, liquid flow control device 100 decreases the liquid flow. The liquid flow control device 100 may control the amplification or reduction of the liquid flow through valves, switches, etc.

Optionally, the system may further include a receiving and displaying device for receiving and displaying the related data.
Wherein, a plurality of detection devices are installed at both ends of the pipe to be detected or installed at intervals according to a preset distance. In some preferred embodiments, a test device with liquid flow control device 100 may be used at the inlet of the pipe under test, and a test device with or without liquid flow control device 100 may be used at the outlet of the pipe under test.

The method performs the following steps S1-S4 using the detecting means of the state of flow of the liquid in the tube in the foregoing embodiment.
In step S1, it is determined whether the liquid to be measured is present in the tube 60 and the liquid to be measured flows, and if so, the liquid flow in the tube is sensed to generate sensed data; if not, the aligning component 40 aligns the detecting body 20 to the vertical state.
In step S2, the flow state data is obtained by operation based on the sensed data. The flow state data here includes the liquid flow direction and the flow rate value.

Data analysis performed by the cloud end comprises characteristics of flow direction consistency, flow rate and the like in different stages and different branch pipes in the same group of pipelines. The data analysis performed by the cloud comprises different stages in the same group of pipelines. Therefore, the flow conditions of different pipelines are controlled in a network control mode.
It should be noted that, data such as the relation between the inclination angle of the detection body 20 and the water flow and the water pressure are tested in a laboratory, then, sensing data is obtained according to the posture of the detection body 20 in an actual test, and the current liquid flowing state data, that is, the water flow and water pressure data, is reversely inquired through the sensing data, so that the test purpose is realized.
