Description

Technical Field

[0001] This utility model relates to the field of air volume detection technology, specifically to a grid measuring device for air volume detection. Background Technology

[0002] Airflow measurement has a significant impact on building energy conservation, and in ventilation and air conditioning systems, vent airflow is a crucial parameter. Appropriate vent airflow settings can significantly reduce energy consumption and improve system efficiency. When vent airflow is set too high, the system needs to consume more energy to maintain air circulation, leading to increased energy consumption. Conversely, setting vent airflow too low may result in decreased indoor air quality, affecting occupant comfort. By accurately measuring and adjusting vent airflow, a comfortable indoor environment can be provided while minimizing energy consumption.

[0003] However, during long-term airflow measurement, the grille is frequently affected by wind and other external factors. After long-term use, the fixing components of the grille may loosen, resulting in uneven airflow or reduced airflow, which reduces the accuracy of airflow measurement, directly affecting building energy conservation and is detrimental to environmental protection. Therefore, it is necessary to design a grille measuring device for airflow measurement to solve the problems mentioned in the background technology. Utility Model Content

[0004] The purpose of this utility model is to provide a grid measuring device for air volume detection. Through the design of fixing bars, fixing holes, fixing components and pressure sensors, the pressure of the installed measuring grid assembly can be monitored so as to detect whether the fixing components are loose in time and take corresponding measures to ensure uniform air output and normal air volume, thereby ensuring the accuracy of air volume detection, which is conducive to building energy conservation and environmental protection, and solves the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

The main body is composed of a digital display controller and a duct mechanism. The duct mechanism includes a measuring grid assembly, a measuring duct body, and a fixing assembly.

A second upper fixing strip and a second lower fixing strip are fixedly installed at the upper and lower ends of the measuring duct body, respectively. A second fixing hole corresponding to the first fixing hole is opened through the second upper and lower fixing strips. A pressure sensor electrically connected to the digital display controller is embedded on the side of the second upper and lower fixing strips near the measuring grid assembly.

[0007] As a preferred embodiment of this utility model, the fixing component is composed of a fixing screw, a forward-rotating nut, and a reverse-rotating nut. The fixing screw passes through the interior of the first fixing hole and the second fixing hole, and the forward-rotating nut and the reverse-rotating nut are screwed on the end of the fixing screw near the interior of the measuring air duct body.

[0008] As a preferred embodiment of this utility model, the outer surface of the fixing screw is provided with a forward and reverse thread section that is compatible with the forward and reverse rotation nuts at one end near the inside of the measuring air duct body. A limit strip is fixedly installed on the outer surface of the fixing screw near the first and second fixing holes.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0021] Example:

[0022] This utility model provides a grid measuring device for air volume detection. Through the design of fixed bars, fixed holes, fixing components and pressure sensors, the pressure of the installed measuring grid assembly can be monitored so as to detect whether the fixing components are loose in time and take corresponding measures to ensure uniform air output and normal air volume, thereby ensuring the accuracy of air volume detection, which is conducive to building energy conservation and environmental protection, and solves the problems mentioned in the background art.

[0023] Please see Figures 1-6 This utility model provides a technical solution:

[0024] A grid measuring device for airflow detection includes a grid measuring device body 1 for detecting energy-saving airflow in buildings. The grid measuring device body 1 is composed of a digital display controller 2 and a duct mechanism 3. The duct mechanism 3 includes a measuring grid assembly 31, a measuring duct body 32, and a fixing assembly 33.

[0025] The measuring grid assembly 31 includes a grid frame 311 fixedly installed on the measuring air duct body 32 near the air outlet. A first upper fixing strip 312 and a first lower fixing strip 313 are fixedly installed at the upper and lower ends of the grid frame 311, respectively. A grid strip 314 is fixedly installed between the first upper fixing strip 312 and the first lower fixing strip 313. First fixing holes 315, adapted to the fixing assembly 33, are provided through the first upper fixing strip 312 and the first lower fixing strip 313. A second upper fixing strip 321 and a second lower fixing strip 322 are fixedly installed at the upper and lower ends of the measuring air duct body 32, respectively. A second fixing hole 323 corresponding to the first fixing hole 315 is provided through the second fixing strip 322. A pressure sensor 324 electrically connected to the digital display controller 2 is embedded in the side of the second upper fixing strip 321 and the second lower fixing strip 322 near the measuring grid assembly 31. The fixing assembly 33 is composed of a fixing screw 331, a forward rotation nut 332 and a reverse rotation nut 333. The fixing screw 331 passes through the interior of the first fixing hole 315 and the second fixing hole 323, and the forward rotation nut 332 and the reverse rotation nut 333 are screwed on the end of the fixing screw 331 near the interior of the measuring air duct body 32. The first upper fixing strip 312 and the second lower fixing strip 322 are fixed together. The lower fixing strip 313 is aligned with the second upper fixing strip 321 and the second lower fixing strip 322 respectively, and the fixing screw 331 passes through the interior of the first fixing hole 315 and the second fixing hole 323. At the same time, the forward rotation nut 332 and the reverse rotation nut 333 are screwed onto the end of the fixing screw 331 near the interior of the measuring air duct body 32. At this time, the measuring grid assembly 31 is fixedly installed on the measuring air duct body 32 near the air outlet. Under the action of the fixing assembly 33, the first upper fixing strip 312 and the second lower fixing strip 313 exert a compressive force on the second upper fixing strip 321 and the second lower fixing strip 322 respectively. Meanwhile, the pressure sensor 32... 4. The extrusion force can be monitored. During long-term air volume monitoring, if the measuring grid assembly 31 is affected by environmental factors such as wind force, causing the fixing component 33 to become loose, the pressure sensor 324 will show a change in pressure value. At the same time, the digital display controller 2 can directly display this value, so as to detect whether the fixing component 33 has become loose in time and take corresponding measures to ensure uniform air output and normal air volume, thereby ensuring the accuracy of air volume detection, which is conducive to building energy conservation and environmental protection. In addition, the design of fixing strips and fixing holes not only makes the measuring grid assembly 31 more stable after installation, but also facilitates the monitoring of whether the fixing component 33 has become loose.

[0026] Furthermore, in this embodiment, please refer to Figure 4 The pressure sensor 324 is provided in four sets. The four sets of pressure sensors 324 are located near the four corners of the grid frame 311, and each set of pressure sensor 324 has a second fixing hole 323 on both sides. Multi-point monitoring is conducive to accurately finding which set of fixing components 33 has become loose, and facilitates quick maintenance and management.

[0027] Furthermore, in this embodiment, please refer to Figure 5 The outer surface of the fixing screw 331, near the inner end of the measuring duct body 32, is provided with a forward and reverse thread section 3311 that matches the forward-rotating nut 332 and the reverse-rotating nut 333. The design of the forward-rotating nut 332, the reverse-rotating nut 333, and the matching forward and reverse thread section 3311 utilizes the opposite forces between forward and reverse rotation to effectively prevent the nut from rotating and loosening, thereby enhancing the stability of the measuring grid assembly 31 after installation and reducing the workload of maintenance and management of the measuring grid assembly 31.

[0028] Furthermore, in this embodiment, please refer to Figure 6 A limiting strip 3312 is fixedly installed on the outer surface of the fixing screw 331 near the first fixing hole 315 and the second fixing hole 323. A fixing cap 3313 is fixedly installed at the end of the fixing screw 331 away from the interior of the measuring air duct body 32. The first fixing hole 315 is composed of a cap groove 3511 and a rod hole 3512. The inner wall of the rod hole 3512 has a first limiting groove 3513 that matches the limiting strip 3312. The inner wall of the second fixing hole 323 has a second limiting groove 3231 that matches the limiting strip 3312. The design of the limiting strip 3312, the first limiting groove 3513, and the second limiting groove 3231 can limit the fixing screw 331 that passes through the first fixing hole 315 and the second fixing hole 323, preventing it from rotating and further enhancing the stability of the measuring grid assembly 31 after installation.

[0029] It should be noted that the digital display controller and pressure sensor are existing technologies, and will not be discussed in detail here.

[0030] In this embodiment, the specific implementation scenario is as follows: During installation, the fixing screw 331 passes through the interior of the first fixing hole 315 and the second fixing hole 323. At the same time, the forward rotation nut 332 and the reverse rotation nut 333 are screwed onto the end of the fixing screw 331 near the interior of the measuring air duct body 32. At this time, the measuring grid assembly 31 is fixedly installed on the measuring air duct body 32 near the air outlet. Under the action of the fixing assembly 33, the first upper fixing strip 312 and the second lower fixing strip 313 exert a squeezing force on the second upper fixing strip 321 and the second lower fixing strip 322, respectively. At the same time, the pressure sensor 324 can monitor this squeezing force. During long-term air volume monitoring, if the measuring grid assembly 31 is affected by environmental factors such as wind force, causing the fixing assembly 33 to loosen, the pressure sensor 324 will show a change in pressure value. At the same time, the digital display controller 2 can directly display this value so as to promptly detect whether the fixing assembly 33 has become loose and take corresponding measures to ensure uniform airflow and normal air volume, thereby ensuring the accuracy of air volume detection and contributing to building energy conservation and environmental protection.

[0031] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
