Description

Technical Field

[0001] This utility model relates to the field of micro-wind anemometer measurement, specifically a micro-pressure anemometer device for measuring air volume in air ducts. Background Technology

[0002] A precision electronic micromanometer is a high-precision instrument widely used for wind speed measurement. It primarily calculates wind speed by measuring pressure changes caused by airflow. The following is a basic method for measuring wind speed with a precision electronic micromanometer. The precision electronic micromanometer operates based on the principle of differential pressure, that is, it calculates wind speed by measuring the minute pressure difference generated by the airflow before and after the sensor. The relationship between wind speed and pressure difference is established using Bernoulli's equation, a fundamental formula in fluid mechanics. When airflow passes through the sensor, the airflow velocity is inversely proportional to the pressure; the greater the velocity, the greater the pressure difference.

[0003] According to the search, existing patents often find that the poor internal airtightness of the device affects the measurement results when performing micro-pressure anemometer measurements. When the measurement is performed, external dust will enter the device with the wind, thus affecting the detection. In addition, the filter is easily clogged.

[0004] Therefore, those skilled in the art have provided a micro-pressure anemometer device for measuring air volume in ducts to solve the problems mentioned in the background art.

[0005] Practical content

This device solves the problems of poor airtightness, complicated maintenance, and the fact that airborne dust can affect the measurement results during micro-pressure anemometer measurements, and that dust can easily clog the filter.

[0008] 2. Technical Solution

[0009] To achieve the above objectives, this utility model provides the following technical solution:

[0010] A micro-pressure anemometer device for measuring air volume in a duct includes a main body, wherein multiple main bodies are arranged in a linear array and are on the same horizontal plane, and an anemometer measuring module is fixedly connected to the top of the outer wall of one of the main bodies, and two closed rings are provided on the outer walls of the multiple main bodies.

[0011] The above technical solution, through the setting of the closed ring and circular plate, makes it convenient to detect and measure the temperature inside the device, facilitates disassembly and maintenance, and ensures the airtightness of the device. The filter screen and ring cylinder are designed to prevent clogging, avoiding the entry of external sand and dust into the device and affecting the measurement of micro-wind speed. Furthermore, manual inspection of the anemometer module before measurement can promptly detect any deviations and allow for timely adjustment, making the air volume and wind speed measurement simpler and more accurate.

[0012] Furthermore, a power module is fixedly connected to the bottom of the anemometer measurement module, and the power module is electrically connected to the anemometer measurement module. Infrared monitoring modules are fixedly connected to both sides of the outer wall of the anemometer measurement module.

[0013] The above technical solution is used to detect whether the filter screen and ring cylinder are blocked, so as to automatically clear the sand. Before the measurement, the operator can perform multiple tests on the anemometer measurement module, so that the anemometer measurement module can be detected in time to detect whether there is any deviation, and thus adjust the anemometer measurement module in time.

[0014] Furthermore, a blower is fixedly connected to the middle of the inner wall of one of the main bodies, the blower is electrically connected to the infrared monitoring module, and a filter screen is fixedly connected to one side of the inner wall of one of the main bodies;

[0016] Furthermore, a conical disc is fixedly connected to the inner wall of one of the main bodies, and a plurality of ring cylinders arranged in a circular array are fixedly connected to one side of the conical disc. The conical disc is placed behind the filter screen, and the infrared monitoring module detects the ring cylinders on one side. When the ring cylinders are detected to be blocked, the blower is turned on to blow air.

[0017] The above technical solution allows the infrared monitoring module to detect blockages in the ring cylinder, enabling the blower to blow air when the ring cylinder is blocked by external wind, sand, or dust.

[0018] Furthermore, the closed ring is C-shaped, and bolts are rotatably connected to both sides of the outer wall of the closed ring. Multiple bolts are vertically aligned with each other, and grooves and inserts are respectively provided on the opposite surfaces of the two corresponding bolts. Gaskets are fixedly connected to the inner sides of the multiple closed rings, and circular grooves are opened on the lower surface of the multiple gaskets.

[0019] By using the above technical solutions, the sealing performance is increased, ensuring that the entire device is seamless and improving the accuracy of detection.

[0020] Furthermore, multiple inserts arranged in a circular array are fixedly connected to both sides of the outer walls of the multiple main bodies. The inserts correspond to the grooves on the lower surface of the gaskets. Mounting plates are fixedly connected to the upper surfaces of the multiple main bodies. A servo motor is fixedly connected to one side of the mounting plate. A first bevel gear is fixedly connected to the output shaft of the servo motor. A temperature sensor is fixedly connected to the other side of the mounting plate.

[0021] The above technical solution allows for the measurement of the inner wall temperature of the device, making its detection capabilities more comprehensive.

[0022] Furthermore, an electric telescopic rod is fixedly connected to the bottom of the thermometer, the electric telescopic rod is signal-connected to the thermometer, and the temperature measuring module of the thermometer is signal-connected to one end of the electric telescopic rod, so that the position touched by one end of the electric telescopic rod can be measured by the thermometer. A circular ring is rotatably connected to the inner wall of the main body.

[0023] Furthermore, the outer wall of the annular plate has multiple grooves corresponding to one end of the electric telescopic rod. A fixing frame is fixedly connected to one side of the annular plate, and a second bevel gear is fixedly connected to the middle of one side of the fixing frame. The second bevel gear and the first bevel gear are on the same horizontal plane and mesh with each other.

[0024] With the above technical solution, the sealing ring is placed at the connection between multiple main bodies, making it easier to disassemble and reassemble the multiple main bodies. After installation, the internal sealing is strong, and the ring plate can be attached to the inside of the main body when the servo motor is turned on, so that the temperature sensor can measure the temperature.

[0036] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of specific embodiments. Obviously, the described specific embodiments are only a part of the specific embodiments of the present invention, and not all of them. Based on the specific embodiments of the present invention, all other specific embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention. Specific implementation method 1:

[0038] Please see Figure 1 , Figure 2 , Figure 4 , Figure 5This embodiment of a micro-pressure anemometer for measuring airflow in a duct includes a main body 1, which consists of multiple main bodies arranged in a linear array on the same horizontal plane. An anemometer measuring module 2 is fixedly connected to the top of the outer wall of one of the main bodies 1. Each of the main bodies 1 has two closed rings 9 on its outer wall, each ring 9 being C-shaped. Bolts 10 are rotatably connected to both sides of the outer wall of each closed ring 9. The bolts 10 are vertically aligned, and the opposite surfaces of the two corresponding bolts 10 are respectively equipped with grooves and inserts. Gaskets 11 are fixedly connected to the inner sides of each of the closed rings 9, and each gasket 11 has a circular groove on its lower surface. Multiple inserts 20 arranged in a circular array are fixedly connected to both sides of the outer wall of each of the main bodies 1, with each insert 20 corresponding to a groove on the lower surface of the gasket 11. A mounting plate 12 is fixedly connected to the upper surface of each of the main bodies 1. A servo motor 13 is fixedly connected to one side, and a first bevel gear 14 is fixedly connected to the output shaft of the servo motor 13. A thermometer 15 is fixedly connected to the other side of the mounting plate 12. An electric telescopic rod 16 is fixedly connected to the bottom of the thermometer 15. The electric telescopic rod 16 and the thermometer 15 are connected by signal. The temperature measurement module of the thermometer 15 is connected by signal to one end of the electric telescopic rod 16, so that the position touched by one end of the electric telescopic rod 16 can be measured by the thermometer. A circular ring plate 17 is rotatably connected to the inner wall of the main body 1. Multiple grooves corresponding to one end of the electric telescopic rod 16 are opened on the outer wall of the circular ring plate 17. A fixing frame 18 is fixedly connected to one side of the circular ring plate 17. A second bevel gear 19 is fixedly connected to the middle of one side of the fixing frame 18. The second bevel gear 19 and the first bevel gear 14 are on the same horizontal plane and mesh with each other.

[0039] The working principle of the above embodiment is as follows: First, the multiple main bodies 1 are attached together at the end. Then, two corresponding closed rings 9 are fixed with bolts 10, so that the groove of the gasket 11 is attached to the outside of the insert block 20, thereby fixing and splicing the multiple main bodies 1. Then, when it is necessary to measure the inner wall temperature of the main body 1, the servo motor 13 is turned on, so that the first bevel gear 14 meshes with the second bevel gear 19 on one side of the fixing frame 18, thereby causing the ring plate 17 to twist. The temperature of the inner wall of the main body 1 is fully collected in the ring plate 17 by rotation. Then, the electric telescopic rod 16 is turned on, so that one end of the electric telescopic rod 16 touches the circular groove of the ring plate 17. Then, the thermometer 15 measures the temperature at the position where the electric telescopic rod 16 is in contact.

[0040] Please see Figure 1 , Figure 2 , Figure 3This embodiment of a micro-pressure anemometer for measuring airflow in a duct includes a main body 1, which consists of multiple main bodies arranged in a linear array on the same horizontal plane. An anemometer measurement module 2 is fixedly connected to the top of the outer wall of one of the main bodies 1. Two closed rings 9 are provided on the outer walls of the multiple main bodies 1. A power module 3 is fixedly connected to the bottom of the anemometer measurement module 2, and the power module 3 and the anemometer measurement module 2 are electrically connected. Infrared monitoring modules 4 are fixedly connected to both sides of the outer wall of the anemometer measurement module 2. A blower 5 is fixedly connected to the middle of the inner wall of one of the main bodies 1, and the blower 5 is electrically connected to the infrared monitoring module 4. A filter screen 6 is fixedly connected to one side of the inner wall of one of the main bodies 1. A conical disc 7 is fixedly connected to the inner wall of another main body 1. Multiple ring cylinders 8 arranged in a circular array are fixedly connected to one side of the conical disc 7. The conical disc 7 is located behind the filter screen 6. The infrared monitoring module 4 detects the blockage on one side of the ring cylinder 8. When the ring cylinder 8 is detected to be blocked, the blower 5 is turned on to blow air.

[0041] This embodiment of a micro-pressure anemometer for measuring airflow in a duct features a closed ring and annular plate. During use, the closed ring can be placed at the connection point between multiple main components, facilitating disassembly and reassembly. After installation, the internal seal is strong. When the servo motor is turned on, the annular plate adheres to the inside of the main component, allowing the temperature sensor to measure the temperature. Multiple manual checks of the anemometer module 2 before measurement allow for timely detection of any deviations, enabling timely adjustments and improving the accuracy of airflow measurement. This enhances overall work efficiency and quality, facilitating temperature detection and measurement within the device, simplifying disassembly and maintenance, and ensuring airtightness. The filter disc and annular cylinder, when activated by the infrared monitoring module, detect blockages in the annular cylinder. If the annular cylinder is clogged by external sand or dust, the blower will blow air, preventing blockages and avoiding the entry of sand and dust into the device, thus preventing interference with micro-pressure anemometer measurements.

[0042] The working principle of the above embodiment is as follows: First, the multiple main bodies 1 are attached together at the end. Then, two corresponding closed rings 9 are fixed with bolts 10, so that the groove of the gasket 11 is attached to the outside of the insert block 20, thereby fixing and splicing the multiple main bodies 1. Then, when it is necessary to measure the inner wall temperature of the main body 1, the servo motor 13 is turned on, so that the first bevel gear 14 meshes with the second bevel gear 19 on one side of the fixing frame 18, thereby causing the annular plate 17 to rotate, and the inner wall temperature of the main body 1 is fully collected in the annular plate 17 by rotation. Then, the electric telescopic rod 16 is turned on, so that one end of the electric telescopic rod 16 touches the circular groove of the annular plate 17. Then, the thermometer 15 measures the temperature at the contact point of the electric telescopic rod 16. Then, when the device measures the micro-pressure anemometer, the staff checks the anemometer measurement module 2 to check whether the anemometer measurement module 2 meets the measurement standard level, and avoids repeated use. The anemometer measurement module 2 deviates after repeated use, affecting the measurement of subsequent air volume and thus hindering the accuracy of the detection equipment. During the measurement of the same wind speed and volume, sand and gravel from the outside are blocked by the filter screen 6. The wind then enters the device through multiple annular cylinders 8 on one side of the cone disc 7. When the power module 3 is turned on, the anemometer measurement module 2 measures the micro-pressure anemometer. However, during the filtration process of the filter screen 6, smaller pieces of sand and gravel still enter the annular cylinders 8 through the gaps in the filter screen 6, eventually clogging them. At this point, the infrared monitoring module 4 is activated, using infrared technology to scan the annular cylinders 8 to prevent clogging. When the clogging of the annular cylinders 8 becomes severe, the infrared technology transmits an activation signal to the blower 5, causing the blower 5 to blow air into the annular cylinders 8, thus clearing the blockage and making them more unobstructed.
