Description

Technical Field

[0001] The utility model relates to a temperature sensor, in particular to a visualized hydraulic parameter measurement sensor integrated system based on flow field reconstruction. Background Art

[0002] Sensor devices are widely used in scientific research, such as chemical sensors, temperature sensors, pressure sensors, and flow sensors in laboratories. Sensors primarily convert physical quantities into measurable electrical signals. Sensors primarily consist of the following components: a sensitive element, a conversion element, a signal conditioning circuit, an interface circuit, a housing, seals, connectors, and a display unit.

[0003] Existing ordinary sensors feedback a single signal at a certain position, and the sensor measurement range is limited (the sensor cannot reflect the signal at a position far away from the sensor). It can be seen that the function of using only the sensor is limited, and the existing sensors are not easy to disassemble for installation in other positions, and the signal cannot be displayed on the display screen in real time. Summary of the Invention

[0004] In order to solve the problem that existing sensors are difficult to disassemble and cannot display signals on the display screen in real time, the utility model needs to provide a visual hydraulic parameter measurement sensor integration system based on flow field reconstruction.

[0005] The utility model provides the following technical solutions:

[0006] A visual hydraulic parameter measurement sensor integrated system based on flow field reconstruction comprises a water hammer wave signal display system, a water hammer wave transmitting system and a water hammer wave signal acquisition system. The water hammer wave signal display system, the water hammer wave transmitting system and the water hammer wave signal acquisition system are connected by a pipeline. The water hammer wave signal display system comprises a signal receiving display, a signal receiving pen and a first detachable pipeline. One end of the signal receiving pen is connected to the signal receiving device, and the other end of the signal receiving device is inserted into an orifice connected to the top of the first detachable pipeline. The water hammer wave transmitting system comprises a connecting pipeline, a second detachable pipeline and an opening and closing valve. The two ends of the connecting pipeline are connected to the second detachable pipeline, and an opening and closing valve (6) is installed on the connecting pipeline. The water hammer wave signal acquisition system comprises a third detachable pipeline, a rotatable support rod, a pressure flow acquisition transmitter, a switch and a connecting pipeline. The two ends of the connecting pipeline are connected to the third detachable pipeline. The pressure flow acquisition transmitter is installed on the connecting pipeline through the rotatable support rod. The pressure flow acquisition transmitter is provided with a switch. The first detachable pipeline, the second detachable pipeline and the third detachable pipeline are connected to the pipeline.

[0007] Furthermore, the signal receiving pen measures the signal of the relevant wave, and the first detachable pipe and the second detachable pipe are installed on the actual pipe in the laboratory. There are two holes on the top to facilitate the signal receiving pen to be inserted into the holes to measure the wave signal.

[0008] Furthermore, the connecting pipe is made of metal and has an arc-shaped longitudinal section.

[0009] Furthermore, the pressure flow acquisition transmitter receives the water hammer wave in the pipeline and sends it to the signal receiving display.

[0010] This application requires a system device that combines sensors and other components (operating components and display components), including a signal receiving display that can receive signals, and this signal receiving display has built-in relevant algorithms to process the received signals, two pressure flow sensors that are easy to disassemble for installation in other locations, and a detachable opening and closing valve. All components are assembled in order to expand the measurable range of the device and enable the measured signals to be displayed instantly on the display screen.

[0011] Compared with existing technologies, the present invention offers the following advantages: the two pressure and flow rate sensors, the on-off valve, and the signal receiving and displaying device can be easily disassembled and placed in a suitable location within the pipeline, making it suitable for a variety of situations within water pipeline systems and relatively easy to install. When a valve is operated, causing a hydraulic transient in the pipeline, the signal receiving and displaying device can instantly reflect the pressure and flow changes at the on-off valve, making the entire process extremely simple. This is much faster and more convenient than traditional pressure and flow sensors that transmit signals to a computer for data processing. BRIEF DESCRIPTION OF THE DRAWINGS

Implementation Method

[0017] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0018] See also Figure 4 The utility model provides a visualized hydraulic parameter measurement sensor integrated system based on flow field reconstruction, including a water hammer wave signal display system, a water hammer wave transmitting system and a water hammer wave signal acquisition system, wherein the water hammer wave signal display system, the water hammer wave transmitting system and the water hammer wave signal acquisition system are connected by pipelines.

[0019] Figure 1 As shown, the water hammer wave signal display system includes a signal receiving display 1, a signal receiving pen 2 and a first detachable pipe 3, one end of the signal receiving pen 2 is connected to the signal receiving display 1, and the other end of the signal receiving pen 2 is inserted into the hole above the first detachable pipe 3.

[0020] The signal receiving display 1 can interact with other electronic devices such as computers, mobile phones, etc., and can complete the relevant flow field reconstruction algorithm, signal data preprocessing algorithm, etc. on the computer, and then the relevant algorithm is built into the signal receiving display. The computer can set the data display mode of the signal receiving display, such as setting the type of data graph (pressure-time statistical graph, flow-time statistical graph) and setting the corresponding scale size of the horizontal and vertical coordinates of the statistical graph. The signal receiving pen 2 can measure the signal of the relevant wave. One end of the signal receiving pen 2 is connected to the signal receiving display 1, and the other end is inserted into the orifice above the first detachable pipe 3. The first detachable pipe 3 and the second detachable pipe 5 can be installed on the actual pipe in the laboratory. There are two orifices on the top, which can facilitate the signal receiving pen to be inserted into the orifice to measure the wave signal. During specific use, the built-in algorithm and relevant data presentation method are pre-set within the signal receiving display. The detachable pipe is then installed on the laboratory pipe. The ends of the two signal receiving pens on the signal receiving display are then inserted into the orifices above the detachable pipe. Rapid valve operation will cause hydraulic transients in the pipe, causing water hammer waves to propagate along the pipe. Ultimately, the signal receiving display receives signals from the pressure and flow sensors and the signal receiving pens. After processing them using the pre-set algorithm, they are displayed in a specific manner on the display. The signal receiving display 1, signal receiving pens 2, and the first detachable pipe together constitute the water hammer wave signal display system.

[0021] Figure 2 In the figure, the water hammer wave emission system includes a connecting pipe 4, a second detachable pipe 5 and an opening and closing valve 6. Both ends of the connecting pipe 4 are connected to the second detachable pipe 5, and the opening and closing valve 6 is installed on the connecting pipe 4.

[0022] The connecting pipe 4 is made of a high-pressure and erosion-resistant metal material. Its longitudinal cross-section is curved, facilitating valve control by the on-off valve 6. The on-off valve 6 and the connecting pipe 4 are connected by orifice bolts, enabling rapid opening and closing of the valve. In practice, the detachable pipe and connecting pipe are installed at the location where hydraulic transients are desired. Rapid operation of the on-off valve can generate water hammer waves in the pipe. The connecting pipe 4, the second detachable pipe 5, and the on-off valve 6 together constitute the water hammer wave emission system.

[0023] Figure 3 In the figure, the water hammer wave signal acquisition system includes a third detachable pipe 7, a rotatable support rod 8, a pressure flow acquisition transmitter 9, a switch 10 and a connecting pipe 11. The two ends of the connecting pipe 11 are connected to the third detachable pipe 7. The pressure flow acquisition transmitter 9 is installed on the connecting pipe 11 through the rotatable support rod 8. The pressure flow acquisition transmitter 9 is provided with a switch 10.

[0024] The pressure and flow sensor module, including the third detachable pipe 7 and the connecting pipe 11, is constructed of a high-pressure and erosion-resistant metal. The connecting pipe 11 has a curved longitudinal section, facilitating the rotation of the rotatable support rod 8. The pressure and flow acquisition transmitter 9 detects water hammer waves in the pipe and transmits them to a pre-configured signal receiving display. The switch 11 controls the opening and closing of the pressure and flow sensor module. In practice, the detachable and connecting pipes are installed on the other side of the on-off valve, a certain distance away. The rotatable support rod 8 is positioned above the orifice of the connecting pipe, and the pressure and flow acquisition transmitter 9 is mounted above the rotatable support rod.

[0025] During normal operation, the water hammer generated at the on-off valve reaches the pressure and flow sensor module after a period of time. The pressure and flow acquisition transmitter 9 processes the received signal and transmits it to the signal receiving display 1. The third detachable pipe 7, rotatable support rod 8, pressure and flow acquisition transmitter 9, switch 10, and connecting pipe 11 together constitute the water hammer signal acquisition system.

[0026] Figure 4 The first detachable pipe 3, the second detachable pipe 5, and the third detachable pipe 7 are connected to the pipeline, wherein two water hammer wave signal acquisition systems are provided, and the two water hammer wave signal acquisition systems are connected and connected with the water hammer wave signal display system and the water hammer wave transmitting system to form a passage.

[0027] Working principle: In the water supply pipeline system, first install the on-off valve at the position where the valve closing operation is required to generate transient flow, then install a pressure flow acquisition transmitter 9 at the appropriate position on both sides of the on-off valve 6, and finally install the signal receiving display 1 next to the on-off valve 6.

[0028] After all the instruments are installed, use the on-off valve 6 to quickly close the valve to generate a water hammer wave. After a certain period of time, the signal receiving display 1 first receives the water hammer wave. After a certain period of time, the pressure and flow acquisition transmitters 9 on both sides receive the water hammer wave and transmit the signal to the signal receiving display 1. According to all the received water hammer waves and the distance algorithm, the signal receiving display can calculate the distance between the two pressure and flow acquisition transmitters 9 and the on-off valve 6 respectively. According to the distance and flow field reconstruction algorithm, the flow and pressure changes at the on-off valve can be reconstructed more accurately, and the flow and pressure changes at the on-off valve 6 can be displayed on the signal receiving display in real time.

[0029] The present invention has the beneficial effect of conveniently disassembling and placing the two pressure and flow rate acquisition transmitters, the on-off valve, and the signal receiving and displaying device at a suitable location within the pipeline. This makes it suitable for a variety of situations within water pipeline systems and is relatively easy to install. When a valve is operated, causing a hydraulic transient in the pipeline, the signal receiving and displaying device can instantly reflect the pressure and flow rate changes at the on-off valve, making the entire process very simple. This is much faster and more convenient than traditional pressure and flow rate sensors that transmit signals to a computer for data processing.

[0030] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
