Description

Technical Field

[0001] This utility model relates to the field of flow monitoring technology, specifically a high-precision airflow measurement device for optimizing airflow paths. Background Technology

[0002] In laboratories, flow monitoring stations are needed to monitor airflow. A search of patent announcement number CN216117501U reveals a portable airtightness atmospheric detector, which includes an air inlet pipe and fixing screws, with a cover plate installed below the air inlet pipe. In this technical solution, the air inlet pipes are symmetrical about the central axis of the frame, and the air inlet pipes form a through structure through the cover plate. The relationship between the air inlet pipes and the frame allows for the uniform entry of external air into the device during use. However, the applicant found that when the airflow is large, air intake is easily obstructed when only the air inlet pipes on both sides are used. Therefore, applying the air inlet pipes in this technical solution to a flow monitoring station affects the accuracy of the measurement. Utility Model Content

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. 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.

[0022] See Figures 1-4 This utility model provides the following two technical solutions:

[0023] The first implementation method: A high-precision airflow measurement device for optimizing airflow path, including a ventilation pipe 1, on which a measurement component 2 is installed. The measurement component 2 relies on the existing differential pressure measurement principle and high-precision sensing technology, combined with Venturi tube or dynamic pressure uniform velocity tube pressure measurement technology, to ensure the accuracy of key parameters such as air volume and airflow velocity. An aluminum honeycomb panel 3 is installed inside the ventilation pipe 1. It has a large area and high ventilation efficiency, which can optimize the airflow path and ensure smooth airflow, thereby greatly improving the measurement accuracy and making the measurement results of air volume and airflow velocity more accurate and stable.

[0024] In order to improve structural strength and prevent deformation of aluminum honeycomb panel 3, an edge sealing assembly is provided on the outside of aluminum honeycomb panel 3, and the edge sealing assembly is fitted and connected to the inner wall of vent pipe 1.

[0025] To facilitate the movement of the aluminum honeycomb panel 3, handles 10 are provided on both sides of the front end of the edge sealing assembly. To fix the aluminum honeycomb panel 3 inside the vent pipe 1, fixing components for fixing the handles 10 to the vent pipe 1 are provided on the handles 10.

[0026] The edge sealing assembly includes two horizontal frames 4 and two vertical frames 5. The two horizontal frames 4 are respectively fitted onto the top and bottom sides of the aluminum honeycomb panel 3, and the two vertical frames 5 are respectively fitted onto the left and right sides of the aluminum honeycomb panel 3. The horizontal frames 4 and vertical frames 5 are both fitted into the inner wall of the vent pipe 1. The horizontal frames 4 and vertical frames 5 are provided around the perimeter to strengthen the outer side of the aluminum honeycomb panel 3 and prevent deformation after long-term use. The two handles 10 are respectively connected to the front end of the two vertical frames 5, and the vertical frames 5 can be moved through the handles 10.

[0027] In order to fix the vertical frame 5 and the horizontal frame 4 together, insert rods 6 are provided at the top and bottom ends of the front and rear sides of the vertical frame 5, and grooves 7 are provided at the left and right ends of the front and rear sides of the horizontal frame 4 for inserting the insert rods 6 horizontally. Bolts 8 that connect to the insert rods 6 are provided horizontally in the grooves 7. To facilitate the insertion of the insert rods 6 into the grooves 7, inclined insertion ports 9 are provided on the grooves 7.

[0028] The fixing assembly includes a fixing rod 11 that runs vertically through the upper and lower ends of the handle 10. The ends of the two fixing rods 11 that are far apart from each other are inserted into the inner wall of the vent pipe 1 to fix the handle 10. A connecting rod 14 is hinged to the opposite side of the two fixing rods 11. The front end of the two connecting rods 14 is hinged to the grip 12. A return spring 13 connected to the handle 10 is provided on the front side of the grip 12. By gripping the grip 12, the return spring 13 is compressed, and the fixing rod 11 can be moved by pulling the connecting rod 14. This makes it convenient to adjust the position of the fixing rod 11 when using the handle 10.

[0029] In order to guide the movement of the grip 12, a guide rod 15 is provided on the front side of the grip 12, which passes through the handle 10.

[0030] The second embodiment differs from the first embodiment in that: an arc-shaped groove is provided on the rear side of the grip 12, and an arc-shaped soft pad 16 is provided on the arc-shaped groove.

[0031] The curved groove is designed to fit the user's fingers for easy grip, and the soft pad 16 increases comfort when gripping.

[0032] This device is suitable for various airflow measurement and control scenarios. Whether it is a controlled environment, exposed control equipment and ventilation system, or pipelines, air outlets and various ventilation equipment, it can be flexibly adapted to fully meet various diverse and complex measurement needs.

[0033] Furthermore, all content not described in detail in this specification is existing technology known to those skilled in the art, and the model parameters of each electrical appliance are not specifically limited; conventional equipment can be used.

[0034] In use, the horizontal frame 4 is vertically fitted onto the aluminum honeycomb panel 3, and then the vertical frame 5 is horizontally fitted onto it, so that the insertion rod 6 is horizontally inserted into the groove 7. Then, it is fixed with bolts 8, which fixes the horizontal frame 4 and the vertical frame 5 together. Then, hold the handles 10 on both sides, and while holding the handles 10, hold the grips 12 on both sides, so that the guide rod 15 on the grip 12 moves forward to compress the return spring 13, which will drive the connecting rods 14 on both sides to pull the fixing rods 11 on both sides to move to the opposite side. Thus, when the aluminum honeycomb panel 3 is inserted into the vent pipe 1, the fixing rods... 11 will not be obstructed by the vent pipe 1. After inserting the aluminum honeycomb panel 3 into the vent pipe 1 and moving it to the installation position, stop. Release the handle 12 and the handle 10. The return spring 13 pushes the handle 12 to move backward, so that the connecting rods 14 on both sides push the fixing rods 11 on both sides to move away from each other. They can then be inserted into the inner wall of the vent pipe 1 to fix the handle 10, so that the handle 10 cannot move back and forth, thereby fixing the aluminum honeycomb panel 3. To disassemble, grip the handle 12 tightly and pull the aluminum honeycomb panel 3 outward to complete the disassembly.
