[0002] A dynamic flow meter is a device used to monitor and calculate changes in the flow rate of fluids (such as liquids, gases, or steam) in real time. It is widely used in industrial process control, energy management, environmental monitoring, and other fields. Dynamic flow meters are a core tool for industrial process optimization and resource management.

[0003] The existing technology has the following shortcomings: Application number 201920960175.5 proposes a pump station flow measurement device based on the volumetric method, specifically relating to the field of flow measurement devices. It includes a main pipeline, a measuring tube fixedly connected to the surface of the main pipeline, a measuring component fixedly mounted on the surface of the measuring tube, a connecting pipe fixedly connected to one end of the measuring component, a calibration component fixedly mounted at the other end of the connecting pipe, a return pipe fixedly connected to the top of the calibration component, and the return pipe fixedly connected to the surface of the main pipeline. The measuring component includes a buffer tank. This invention uses a liquid level sensor to transmit liquid volume change data to a microcontroller within a display screen. Combined with the volume of the measuring tank, the microcontroller, in conjunction with an automatic timer, can calculate two sets of flow measurement data. By comparing the two sets of calculation results, more accurate flow measurement data is obtained and displayed on the display screen, thus achieving the goal of precise measurement.

[0004] The aforementioned equipment uses electronic components such as water immersion sensors, liquid level sensors, automatic timers, and displays, combined with a microcontroller, to measure flow rate. It relies on electricity, and the electronic components are easily damaged in humid, high-temperature, and corrosive environments (such as chemical plants and mines), affecting normal operation. Furthermore, its complex structure increases the failure rate of the device. In addition, if the fluid measured by the aforementioned equipment contains mud, oil, or air bubbles, the instability of the flowing medium can easily lead to data deviation. Utility Model Content

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figure 1-6 In this embodiment: a dynamic flow measurement device includes a measurement device 1 and a medium flow pipe 5. A fixed rod 2 is provided on the outside of the measurement device 1. An instrument panel 3 is provided on the fixed rod 2. A pointer 4 is provided inside the instrument panel 3.

A pendulum 8 is provided at the outer end of the connecting rod 7. A transmission rod 9 is provided on the outside of the connecting rod 7. A damping spring 10 is provided on the outside of the top fixing member 6. A bearing 11 is provided at one end of the connecting rod 7. An installation groove 12 is opened at the upper end of the pendulum 8. Rotary grooves 13 are opened at both ends of the top fixing member 6.

[0027] The fixing rod 2 facilitates the fixed installation of the instrument panel 3 on the outside of the measuring device 1. The bearing 11 ensures the rotational flexibility between the connecting rod 7 and the rotating groove 13. The rotating groove 13 facilitates the connection of the connecting rod 7.

[0028] The pendulum 8 is specifically composed of a shell 801, a support frame 802 and a flexible rubber layer 803. The support frame 802 is provided inside the shell 801 and the flexible rubber layer 803 is provided on the outside of the shell 801.

[0029] The support frame 802 ensures the structural stability of the outer shell 801. The pendulum 8 swings under the impact of the flowing medium, and the swing angle of the pendulum 8 increases with the increase of the flow rate.

[0030] In this embodiment, there are four sets of fixing rods 2. One end of the fixing rod 2 is fixedly connected to the outside of the measuring device 1. The instrument panel 3 is fixedly installed on the other end of the fixing rod 2. There is a threaded connection between the medium flow pipe 5 and the measuring device 1. The top fixing part 6 is fixedly installed on the top of the inner wall of the measuring device 1. One end of the connecting rod 7 is fixedly installed in the inner ring of the bearing 11. The rotating groove 13 is adapted to the outer ring of the bearing 11. The outer ring of the bearing 11 is fixedly embedded in the rotating groove 13. The connecting rods 7 on both sides of the top fixing part 6 have the same installation structure. The mounting groove 12 is adapted to the connecting rod 7. The other end of the connecting rod 7 is fixedly installed in the mounting groove 12. One end of the transmission rod 9 is fixedly connected to the outside of one set of connecting rods 7. The transmission rod 9 corresponds to the bearing 11.

[0031] Specifically, the top fixing piece 6 provides the mounting conditions for the connecting rod 7 and the damping spring 10, and the transmission rod 9 can transmit the rotational power of the connecting rod 7 to the pointer 4, so that the pointer 4 indicates on the instrument panel 3.

[0032] In this embodiment, one end of the transmission rod 9 extends out of the measuring device 1 and passes through the instrument panel 3. The pointer 4 is fixedly connected to the outer end of the transmission rod 9 and is perpendicular to the transmission rod 9. There are two sets of damping springs 10, which are distributed on both sides of the top fixing member 6. One end of the damping spring 10 is fixedly connected to the side of the top fixing member 6, and the other end of the damping spring 10 is fixedly connected to the outside of the pendulum 8. The two sets of damping springs 10 are symmetrically arranged and have the same installation structure. The support frame 802 is fixedly installed inside the outer shell 801. Both the support frame 802 and the outer shell 801 are made of aluminum. The flexible rubber layer 803 is fixedly covered on the outside of the outer shell 801.

[0033] Specifically, the damping spring 10 can absorb the instantaneous impact of the flowing medium, allowing the pendulum 8 to swing smoothly, keeping the pointer 4 stable, and avoiding the impact fluctuations from affecting the reading of the pointer 4. The flexible rubber layer 803 can make the flowing medium fit the pendulum 8 more closely and smoothly transmit the thrust, ensuring the normal swing of the pendulum 8.

[0034] The working principle and usage process of this utility model are as follows: In actual use, the two ends of the equipment are threadedly connected to the corresponding medium flow pipes 5. When the medium flows through the medium flow pipes 5, it passes through the measuring device 1. The impact of the flowing medium drives the pendulum 8 to swing. The swing angle of the pendulum 8 increases with the increase of the flow rate. The swing angle of the pendulum 8 is directly proportional to the flow rate. During the swing of the pendulum 8, the connecting rod 7 drives the transmission rod 9 to rotate. At the same time, the transmission rod 9 drives the pointer 4 to rotate. The swing amplitude of the pendulum 8 is indicated on the instrument panel 3 by the pointer 4, thereby completing the calculation of the flow rate in the medium flow pipes 5. During the swing of the pendulum 8, the damping spring 10 can absorb the instantaneous impact of the flowing medium, so that the pendulum 8 can swing smoothly, keep the pointer 4 stable, and avoid the impact fluctuations affecting the pointer. The reading of needle 4 is achieved through a purely mechanical structure, eliminating the need for circuit boards, batteries, or sensors, thus completely freeing it from dependence on electricity. The mechanical structure is resistant to flooding, high temperatures, and corrosive environments (such as chemical plants and mines). The core components are only the pendulum 8, transmission rod 9, pointer 4, damping spring 10, and connecting rod 7, without complex gear sets or moving seals. The structure is simple and reliable, reducing the overall failure rate. If the medium flowing in the medium flow pipe 5 contains mud, oil, or air bubbles, the medium will act on the flexible rubber layer 803 on the outside of the pendulum 8 when pushing it. The flexibility of the rubber layer 803 allows the medium to fit more closely to the pendulum 8 and smoothly transmit the thrust, ensuring the normal swing of the pendulum 8 and avoiding deviations in the measured data due to the instability of the flowing medium.
