Description

Technical Field

[0001] This utility model is a ground-based flue gas furnace equipped with a vertical airflow detection device, belonging to the field of flue gas furnace technology. Background Technology

[0002] In meteorological and environmental science research, understanding vertical airflow in the atmosphere is crucial for weather forecasting, air quality assessment, and climate model building. Existing ground-based smoke generators typically include a combustion chamber, a chimney, and possibly some basic monitoring equipment (such as temperature and humidity sensors). Traditional ground-based smoke generators are mainly used to generate visible smoke to facilitate the observation of wind direction and speed.

[0003] However, they often lack the function of being specifically designed to accurately measure the characteristics of vertical airflow. Their function is limited under complex weather conditions, and they cannot provide specific data on the speed and direction of vertical airflow. There is an urgent need for a ground-based flue gas furnace equipped with a vertical airflow detection device to solve the above-mentioned problems. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a ground-based flue gas furnace equipped with a vertical airflow detection device to solve the problems mentioned in the background technology. This utility model adopts a combination of multiple ultrasonic anemometers and lidar technology to monitor vertical airflow in real time, provide high-precision vertical airflow data, and enhance meteorological observation capabilities.

[0005] To achieve the above objectives, this utility model employs the following technical solution: a ground-based flue gas furnace equipped with a vertical airflow detection device, comprising a flue gas furnace body and a conical hood. A flue gas furnace fixing cylinder is fixed to the upper end of the flue gas furnace body via a flange and bolts. An internal thread is provided at the upper end of the flue gas furnace fixing cylinder. An external threaded cylinder is welded to the lower end of the conical hood. The external threaded cylinder is screwed into the upper end of the flue gas furnace fixing cylinder via threads. An embedded ring is horizontally fixed to the lower end of the external threaded cylinder via multiple hand-tightened screws. Multiple extension columns are longitudinally welded to the lower end of the embedded ring. An ultrasonic transmitter is obliquely adhered to the inner side of each of the extension columns. Multiple hollow connecting pipes are welded inside the embedded ring. A radar mounting base is welded between the multiple hollow connecting pipes. A lidar is longitudinally mounted inside the radar mounting base via threads. Multiple ultrasonic receivers are adhered at equal angles to the outer surface of the radar mounting base. The multiple ultrasonic receivers and the multiple ultrasonic transmitters together constitute an ultrasonic anemometer.

[0006] Furthermore, the plurality of ultrasonic receivers are respectively oriented toward the transmitting ends of the plurality of ultrasonic transmitters.

[0007] Furthermore, a control panel is installed at the front end of the main body of the smoke generator, and the control panel is connected to a lidar and multiple ultrasonic anemometers via wires.

[0008] Furthermore, some of the wires pass through multiple hollow connecting tubes.

[0009] Furthermore, support legs are welded around the lower end of the main body of the flue gas stove.

[0010] Furthermore, the multiple support legs are bolted to the external ground.

[0011] Furthermore, an acoustic radar is installed on the upper end of the conical shroud, and longitudinal guide holes are opened around the upper circumference of the conical shroud.

[0012] The beneficial effects of this utility model are as follows: This utility model is a ground-based smoke generator equipped with a vertical airflow detection device. Because this utility model adds a conical hood, an external threaded cylinder, an inner ring, a hand-tightening screw, an extension column, an ultrasonic transmitter, a radar mounting base, a lidar, and an ultrasonic receiver, the structure is reasonable. It adopts a combination of multiple ultrasonic anemometers and lidar technology to monitor vertical airflow in real time, provide high-precision vertical airflow data, enhance meteorological observation capabilities, and the modular installation structure facilitates disassembly, maintenance, or replacement, making it highly practical.

Detailed Implementation

[0018] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0019] Please see Figures 1-3This utility model provides a technical solution: a ground-based smoke generator equipped with a vertical airflow detection device, including a smoke generator body 14 and a conical cover 4. The upper end of the smoke generator body 14 is fixed with a smoke generator fixing cylinder 1 by a flange and bolts. The upper end of the smoke generator fixing cylinder 1 is provided with an internal thread. The lower end of the conical cover 4 is welded with an external thread cylinder 5. The external thread cylinder 5 is screwed into the upper end of the smoke generator fixing cylinder 1 by threads. The lower end of the external thread cylinder 5 is horizontally fixed with an embedded ring 6 by multiple hand-tightening screws 7. The lower end of the embedded ring 6 is longitudinally welded with multiple extension columns 8. The inner sides of the multiple extension columns 8 are inclined and attached with ultrasonic transmitters 9. The embedded ring 6 is welded with multiple hollow connecting pipes 10. The middle of the multiple hollow connecting pipes 10 is welded with a radar mounting base 11. The radar mounting base 11 is longitudinally installed with a laser radar 12 by threads. The outer surface of the radar mounting base 11 is attached with multiple ultrasonic receivers 13 at equal angles. The multiple ultrasonic receivers 13 and the multiple ultrasonic transmitters 9 constitute an ultrasonic anemometer. This design solves the problem that traditional ground-based smoke generators are inconvenient to measure vertical airflow characteristics.

[0020] As the first embodiment of this utility model: multiple ultrasonic receivers 13 are respectively oriented towards the transmitting ends of multiple ultrasonic transmitters 9. By adding multiple ultrasonic receivers 13 respectively oriented towards the transmitting ends of multiple ultrasonic transmitters 9, when there is no wind, the time required for an ultrasonic transmitter 9 to transmit from one probe to the ultrasonic receiver 13 on the opposite side is fixed. If there is wind, especially vertical airflow, the airflow will affect the propagation path of the ultrasonic wave, causing the propagation time to change. Specifically, the propagation speed of the sound wave is faster in the downwind direction and slower in the upwind direction. By measuring the difference in ultrasonic propagation time in different directions with multiple sets of ultrasonic anemometers and combining it with the known distance, the wind speed components in each direction can be calculated. Further processing of these data can yield three-dimensional wind field information, including vertical airflow. A control panel 2 is installed at the front end of the main body 14 of the flue gas furnace. The control panel 2 is connected to the lidar 12 and multiple ultrasonic anemometers via wires. The lidar 12 emits short-pulse laser beams into the fixed cylinder 1 of the flue gas furnace. These pulses are scattered when they encounter particles (such as dust, water vapor condensation nuclei, etc.) in the fixed cylinder 1 of the flue gas furnace. Some of the scattered laser energy is captured by the lidar. If there are moving particles (such as particles that rise or fall with the airflow) in the fixed cylinder 1 of the flue gas furnace, they will produce a Doppler frequency shift on the incident laser. By accurately measuring this frequency shift, the velocity information of the particles can be obtained, and the airflow velocity in the fixed cylinder 1 of the flue gas furnace can be inferred. Some wires pass through multiple hollow connecting pipes 10. Support legs 3 are welded around the lower end of the main body 14 of the flue gas furnace. Multiple support legs 3 are bolted to the external ground. The addition of multiple support legs 3 and bolts to the external ground facilitates the installation and fixation of the main body 14 of the flue gas furnace. An acoustic radar is installed on the upper end of the conical cover 4. Longitudinal guide holes are opened around the upper end of the conical cover 4. The longitudinal guide holes facilitate the upward flow of air in the flue gas furnace fixing cylinder 1. The acoustic radar is connected to the main body 14 of the flue gas furnace through a line and uses a filtering algorithm to emit acoustic pulses upward and receive atmospheric turbulence scattering signals. The vertical wind speed is calculated through the Doppler effect. The vertical height is 0-3km and the resolution is 50-100m, so as to measure the vertical airflow above the main body 14 of the flue gas furnace.

[0021] As a second embodiment of this utility model: the embedded ring 6 is horizontally inserted into the external threaded cylinder 5, and then multiple hand-tightening screws 7 are used to fix the embedded ring 6 in the external threaded cylinder 5. Next, the external threaded cylinder 5 is screwed into the upper part of the smoke furnace fixing cylinder 1. At this time, multiple sets of ultrasonic anemometers and lidar 12 are located inside the smoke furnace fixing cylinder 1. Then, the control panel 2 is connected to the lidar 12 and multiple sets of ultrasonic anemometers via wires for detection. When there is no wind, the time required for the ultrasonic transmitter 9 to transmit from one probe to the ultrasonic receiver 13 on the opposite side is fixed. If there is wind, especially vertical airflow, the airflow will affect the propagation path of the ultrasonic waves, causing the propagation time to change. Specifically, the sound wave propagation speed is faster in the downwind direction and slower in the upwind direction. By measuring the difference in ultrasonic propagation time in different directions inside the smoke furnace fixing cylinder 1 using multiple sets of ultrasonic anemometers, and combining this with the known distance, the wind speed components in each direction can be calculated. These data can then be further processed. According to the data, the three-dimensional wind field information, including the vertical airflow inside the smoke furnace fixed cylinder 1, can be obtained. The lidar 12 emits short-pulse laser beams into the smoke furnace fixed cylinder 1. These pulses are scattered when they encounter particles (such as dust, water vapor condensation nuclei, etc.) in the smoke furnace fixed cylinder 1. Some of the scattered laser energy is captured by the lidar. If there are moving particles (such as particles that rise or fall with the airflow) in the smoke furnace fixed cylinder 1, they will produce a Doppler frequency shift on the incident laser. By accurately measuring this frequency shift, the velocity information of the particles can be obtained, and then the airflow velocity inside the smoke furnace fixed cylinder 1 can be inferred. In addition, the opening of the longitudinal guide hole facilitates the upward flow of airflow inside the smoke furnace fixed cylinder 1. The installed acoustic radar is connected to the smoke furnace body 14 by a line and uses a filtering algorithm to emit acoustic pulses upward and receive atmospheric turbulence scattering signals. The vertical wind speed is calculated by the Doppler effect, with a vertical height of 0-3km and a resolution of 50-100m, so as to measure the vertical airflow above the smoke furnace body 14.
