A wind speed sensing draft gauge

Abstract

This utility model discloses a wind speed sensing and measuring air valve, relating to the field of wind speed measuring air valves. It includes an air valve with multiple sets of air plates installed inside. A drive column is fixed to one side of each of the two sets of air plates. A slider is installed at the end of the drive column. A drive frame is fitted around the outer wall of the slider. A connecting rod is fixed to one side of the drive frame, and the end of the connecting rod is connected to an air measuring plate. When the airflow inside the air valve increases, the air blows the air measuring plate, causing it to flip. The air measuring plate pushes the drive frame via the connecting rod.

During the flipping process, the air plates, through the meshing connection between multiple sets of gears, drive other air plates to flip as well, thereby changing the opening gap between the multiple sets of air plates and reducing the amount of air flowing through them.

Description

Technical Field

[0001] This utility model relates to the field of speed measuring air valves, specifically a wind speed sensing and speed measuring air valve. Background Technology

[0002] As a key component of air conditioning and ventilation systems, air valves are devices that can regulate airflow and direction through manual or automatic control. They typically consist of a valve body, blades, and a drive unit. By changing the angle or opening degree of the blades, they can effectively control the airflow within the ventilation duct. They are widely used in air conditioning, ventilation, and smoke extraction systems of various buildings to meet the air environment requirements in different scenarios.

[0003] During the operation of the supermarket's air conditioning system, the cold air generated by the main air conditioning unit is transported through pipes to multiple sets of air valves distributed throughout the supermarket. These air valves, after reasonable design and installation, are arranged on the ceiling inside the supermarket, becoming an important channel for cold air to enter the supermarket space. When the air conditioning system is started, the cold air is driven by the pressure in the pipes and diffuses into the interior of the supermarket through the openings of the air valves, thereby regulating the indoor temperature of the supermarket and creating a relatively comfortable shopping and working environment for customers and staff.

[0004] Because the flow direction of cold air in pipes and valves is difficult to control precisely, and factors such as pipe layout and valve installation location affect the flow of cold air, uneven distribution of cold air occurs when passing through the valves. This results in some valves releasing more cold air per unit time, while others release less cold air, ultimately leading to a severely uneven distribution of cold air inside the supermarket. Utility Model Content

[0005] Based on this, the purpose of this utility model is to provide a wind speed sensing and measuring air valve to solve the technical problem that it is difficult to automatically control the flow rate of cold air flowing out of the air valve per unit time.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a wind speed sensing and measuring air valve, comprising an air valve, wherein multiple sets of air plates are installed inside the air valve, connecting columns are fixed at both ends of the air plates, gears are sleeved on the outer wall of the connecting columns, a drive column is fixed on one side of the two sets of air plates, a slider is installed at the end of the drive column, a drive frame is sleeved on the outer wall of the slider, a connecting rod is fixed on one side of the drive frame, a first fixing block is connected to the end of the connecting rod, a wind measuring plate is installed at the end of the first fixing block, and multiple sets of guide plates are installed inside the air valve.

[0007] By adopting the above technical solution, the problem of the air valve's inability to automatically control the flow rate of cold air per unit time is solved. When the air flow rate inside the air valve increases, the air blows the measuring plate to flip. The measuring plate pushes the drive frame through the connecting rod. When the drive frame moves, it pushes two sets of sliders through the internal sliding groove. The sliders push the air plate through the drive column, causing the air plate to flip. During the flipping process, the air plate drives other air plates to flip through the meshing connection between multiple sets of gears, thereby changing the opening gap between multiple sets of air plates, thus reducing the amount of air flowing through the air plate.

[0008] The present invention is further provided that the interior of the drive frame is provided with a sliding groove, and the sliding groove is configured to be arc-shaped.

[0009] Preferably, when the drive frame moves, the two sets of sliders can move inside the drive frame along the arc-shaped groove, which can reduce the resistance of the inner wall of the drive frame to the slider sliding.

[0010] The present invention is further configured such that a second fixing block is installed on one side of the wind measuring plate, one end of the second fixing block is connected to a first fixing column, and the first fixing column is fixedly installed on the top of the inner wall of the wind valve.

[0011] Preferably, when air blows the wind measuring plate, the wind measuring plate rotates around the bottom of the first fixed column.

[0012] The present invention is further configured such that connecting balls are installed at the ends of the connecting rod and the first fixing column, and the two sets of connecting balls are respectively disposed inside the first fixing block and the second fixing block.

[0013] Preferably, when the wind measuring plate flips, the wind measuring plate can push the connecting rod through the connecting ball, and the connecting ball connected to the end of the first fixed column can cause the wind measuring plate to flip on one side of the first fixed column.

[0014] The present invention is further configured such that the diameter of the wind measuring plate is smaller than the inner wall diameter of the air valve, and the wind measuring plate is installed at an angle, with the wind measuring plate tilted toward the drive frame.

[0015] Preferably, when the air velocity inside the air valve increases, the air pushes the wind measuring plate to tilt towards one side of the drive frame.

[0016] The present invention is further configured such that a spring is installed on one side of the wind measuring plate, and a second fixing post is connected to the end of the spring, and the second fixing post is fixedly installed on the top of the inner wall of the wind valve.

[0017] Preferably, during the flipping process of the wind measuring plate, the wind measuring plate stretches the spring. When the air flow rate decreases, the spring in the stretched state pulls the wind measuring plate back to the initial position. The wind measuring plate also pulls the two sets of sliders to one side through the drive frame, so that the wind plate flips open at a certain angle, thereby increasing the air flow from the air valve.

[0018] The present invention is further configured such that a limiting plate is provided at the end of the connecting column, and the limiting plate is movably installed inside the air valve.

[0019] Preferably, the limiting plate limits and fixes the air plate through the connecting column, so that the air plate is stably installed inside the air valve.

[0020] The present invention is further configured such that a rotating column is fixed at the end of the connecting column, and multiple sets of ball bearings are installed on the outer wall of the rotating column.

[0021] Preferably, when the air plate rotates, the air plate drives the rotating column to rotate through the connecting column, and the multiple sets of ball bearings installed inside the rotating column can reduce the friction between the rotating column and the inner wall of the air valve.

[0022] In summary, the present invention has the following main advantages:

[0023] 1. This utility model solves the problem of the difficulty in automatically controlling the flow rate of cold air from the air valve per unit time by setting up an air valve, an air measuring plate, a slider, a drive frame, a connecting rod, and an air plate. When the air flow rate inside the air valve increases, the air blows the air measuring plate to flip. The air measuring plate pushes the drive frame through the connecting rod. When the drive frame moves, it pushes two sets of sliders through the internal sliding groove. The sliders push the air plate through the drive column, causing the air plate to flip. During the flipping process, the air plate drives other air plates to flip through the meshing connection between multiple sets of gears, thereby changing the opening gap between multiple sets of air plates, thus reducing the amount of air flowing through the air plate.

[0024] 2. This utility model, by setting a second fixed column, a spring, an air measuring plate, a second fixed block, and a first fixed column, allows the air measuring plate to rotate around the bottom of the first fixed column when air blows on it. During the rotation of the air measuring plate, the air measuring plate stretches the spring. When the air velocity decreases, the stretched spring pulls the air measuring plate back to its initial position. Furthermore, the air measuring plate pulls the two sets of sliders to one side through the drive frame, causing the air plate to rotate and open at a certain angle, thereby increasing the airflow from the air valve.

[0032] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0033] The embodiments of this utility model will be described below based on its overall structure.

[0034] First embodiment:

[0035] Please see Figure 1 — Figure 4The system includes a damper 1, with multiple sets of damper plates 2 installed inside. Connecting columns 303 are fixed to both ends of the damper plates 2, and gears 4 are fitted onto the outer walls of the connecting columns 303. A drive column 5 is fixed to one side of each set of damper plates 2, and a slider 501 is installed at the end of the drive column 5. A drive frame 6 is fitted onto the outer wall of the slider 501, and a connecting rod 602 is fixed to one side of the drive frame 6. A first fixing block 604 is connected to the end of the connecting rod 602, and a wind measuring plate 7 is installed at the end of the first fixing block 604. Multiple sets of guide plates 101 are installed inside the damper 1, solving the problem of difficulty in automatically controlling the unit time of flow from the damper. Regarding the issue of internal airflow, when the airflow inside the air valve 1 increases, the air blows the air measuring plate 7, causing it to flip. The air measuring plate 7 pushes the drive frame 6 via the connecting rod 602. When the drive frame 6 moves, it pushes two sets of sliders 501 via the internal sliding groove 601. The sliders 501 push the air plate 2 via the drive column 5, causing the air plate 2 to flip. During the flipping process of the air plate 2, the air plate 2 drives other air plates 2 to flip through the meshing connection between multiple sets of gears 4, thereby changing the opening gap between multiple sets of air plates 2, thus reducing the amount of air flowing through the air plate 2.

[0036] For details regarding the above embodiments, please refer to [link / reference]. Figure 3 The drive frame 6 has a sliding groove 601 inside. The sliding groove 601 is arc-shaped. When the drive frame 6 moves, the two sets of sliders 501 can move inside the drive frame 6 along the arc-shaped sliding groove 601. The arc-shaped sliding groove 601 can reduce the resistance force of the inner wall of the drive frame 6 on the sliding of the sliders 501.

[0037] For details regarding the above embodiments, please refer to [link / reference]. Figure 2 A second fixing block 702 is installed on one side of the wind measuring plate 7. One end of the second fixing block 702 is connected to a first fixing post 701, and the first fixing post 701 is fixedly installed on the top of the inner wall of the air valve 1. When the air blows the wind measuring plate 7, the wind measuring plate 7 flips around the bottom end of the first fixing post 701.

[0038] For details regarding the above embodiments, please refer to [link / reference]. Figure 2 and Figure 3 Connecting balls 603 are installed at the ends of connecting rod 602 and first fixed column 701, and two sets of connecting balls 603 are respectively disposed inside the first fixed block 604 and the second fixed block 702. When the wind measuring plate 7 flips, the wind measuring plate 7 can push the connecting rod 602 through the connecting balls 603, and the connecting balls 603 connected to the end of the first fixed column 701 can make the wind measuring plate 7 flip on one side of the first fixed column 701.

[0039] For details regarding the above embodiments, please refer to [link / reference]. Figure 2The diameter of the wind measuring plate 7 is smaller than the inner wall diameter of the air valve 1, and the wind measuring plate 7 is installed at an angle and tilted towards the drive frame 6. When the air flow rate inside the air valve 1 increases, the air pushes the wind measuring plate 7 to tilt towards the drive frame 6.

[0040] For details regarding the above embodiments, please refer to [link / reference]. Figure 2 A spring 801 is installed on one side of the wind measuring plate 7. The end of the spring 801 is connected to a second fixing post 8, and the second fixing post 8 is fixedly installed on the top of the inner wall of the air valve 1. During the flipping process of the wind measuring plate 7, the wind measuring plate 7 stretches the spring 801. When the air flow rate decreases, the spring 801 in the stretched state pulls the wind measuring plate 7 back to the initial position. The wind measuring plate 7 pulls the two sets of sliders 501 to one side through the drive frame 6, so that the air plate 2 flips open at a certain angle, thereby increasing the air flow rate from the air valve 1.

[0041] For details regarding the above embodiments, please refer to [link / reference]. Figure 4 The end of the connecting column 303 is provided with a limiting plate 302, and the limiting plate 302 is movably installed inside the air valve 1. The limiting plate 302 limits and fixes the air plate 2 through the connecting column 303, so that the air plate 2 is stably installed inside the air valve 1.

[0042] For details regarding the above embodiments, please refer to [link / reference]. Figure 4 The end of the connecting column 303 is fixed with a rotating column 3, and multiple sets of ball bearings 301 are installed on the outer wall of the rotating column 3. When the air plate 2 rotates, the air plate 2 drives the rotating column 3 to rotate through the connecting column 303. The multiple sets of ball bearings 301 installed inside the rotating column 3 can reduce the friction between the rotating column 3 and the inner wall of the air valve 1.

[0043] Second embodiment:

[0044] Please see Figure 5 A fixing rod 9 is fixed to the top of the inner wall of the air valve 1. A limit groove 901 is opened at the bottom of the fixing rod 9, and a limit block 902 is installed inside the limit groove 901. The limit block 902 is fixed to the top of the drive frame 6. When the drive frame 6 moves, the fixing rod 9 limits the drive frame 6 through the limit block 902, so that the drive frame 6 always moves horizontally during the movement.

[0045] In practical operation, when the airflow inside the air valve 1 increases, the air blows the air measuring plate 7 to rotate around the bottom of the first fixed column 701. During the rotation of the air measuring plate 7, the air measuring plate 7 stretches the spring 801, and the air measuring plate 7 pushes the drive frame 6 through the connecting rod 602. When the drive frame 6 moves, the drive frame 6 pushes the two sets of sliders 501 through the internal sliding groove 601. The sliders 501 push the air plate 2 through the drive column 5, causing the air plate 2 to rotate around the connecting column 303. During the rotation of the air plate 2, the sliders 501 move closer to each other in the sliding groove 601, and the rotation of the air plate 2 drives the gear 4 to rotate through the connecting column 303. The air plate 2 drives other air plates 2 to rotate through the meshing connection between multiple sets of gears 4, thereby changing the unfolding gap between multiple sets of air plates 2.

The specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.
