Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0018] Example 1 Please see Figures 1-7 The illustrated airflow matrix dustproof device includes a main pipeline 101 and branch pipelines disposed on both sides of the main pipeline 101. The branch pipelines consist of a static pressure pipe 102 and a negative pressure pipe 103. The static pressure pipe 102 and the negative pressure pipe 103 are connected to the main pipeline 101 via a connecting pipe 104. An airflow detection rod 105 is disposed on the static pressure pipe 102. The device also includes: An additional swing component is installed on the airflow detection rod 105 to assist the airflow detection rod 105 in swinging, and the static pressure tube 102 achieves dust prevention by increasing the swing. A sliding component is provided on the pendulum-enhancing component to assist in sliding during the pendulum-enhancing process; And, a pushing component for squeezing and pushing during sliding and a reset component for resetting after squeezing, provided on the pendulum extension component; It should be noted that during the use of the air volume measurement matrix, an oscillating component is pre-installed on the airflow detection rod 105 of the static pressure pipe 102. With the use of the air volume measurement matrix, the interaction between the turbulent flow field inside the use position of the air volume measurement matrix and the oscillating plate 202 causes the airflow detection rod 105 to oscillate. Through oscillation, dust and particles attached to the static pressure pipe 102 can be shaken off. In addition, the tiny airflow vortex generated by the oscillation can blow away impurities accumulated near the static pressure pipe 102, preventing them from forming a dense blockage layer and achieving a dustproof effect.

[0019] Preferably, the swing-enhancing component includes a mounting sleeve 201, a first mounting component for assisting installation is provided between the mounting sleeve 201 and the airflow detection rod 105, a swing plate 202 for assisting swing is provided on one side of the mounting sleeve 201, and a connecting component for assisting the swing plate 202 is provided between the mounting sleeve 201 and the swing plate 202. It should be noted that after the swing-up component is installed, along with the use of the air volume measurement matrix, the interaction between the turbulent flow field inside the air volume measurement matrix and the swing plate 202 causes the swing plate 202 to move under force. During the process of the swing plate 202 being subjected to force, through the connection of the mounting plate 404, the lifting platform 403, the reset component and the sliding seat 402, and the sliding guide effect of the arc rod 602, the swing plate 202 is subjected to force to reciprocate around the outside of the mounting ring 401 and collide with the mounting ring 401. During the collision process, through the connection between the mounting ring 401 and the mounting sleeve 201, the airflow detection rod 105 is driven to swing. Through the swing, dust and particles attached to the static pressure pipe 102 can be shaken off. In addition, the tiny airflow vortex generated by the swing can blow away the impurities accumulated near the static pressure pipe 102, preventing them from forming a dense blockage layer and achieving the dustproof effect.

[0020] Preferably, the connecting assembly includes a mounting ring 401 sleeved on the outside of the mounting sleeve 201, a sliding seat 402 provided on the mounting ring 401, a sliding assembly disposed between the mounting ring 401 and the sliding seat 402, a lifting platform 403 provided on the sliding seat 402, a reset assembly disposed between the lifting platform 403 and the sliding seat 402, a mounting plate 404 fixed on the lifting platform 403, and a second mounting assembly for assisting installation disposed between the mounting plate 404 and the swing plate 202; It should be noted here that: through the interaction between the turbulent flow field inside the air volume measurement matrix and the oscillating plate 202, the oscillating plate 202 is subjected to force and moves. During the process of the oscillating plate 202 being subjected to force, through the connection of the mounting plate 404, the lifting platform 403, the reset component and the sliding seat 402, and the sliding guide effect of the arc rod 602, the oscillating plate 202 is subjected to force and reciprocates around the outside of the mounting ring 401 and collides with the mounting ring 401.

[0021] Preferably, the sliding assembly includes an arc-shaped groove 601 formed on the outer side of the mounting ring 401, and multiple sets of arc-shaped rods 602 are fixed inside the arc-shaped groove 601, with the sliding seat 402 slidably connected to the arc-shaped rods 602; It should be noted here that the arc-shaped groove 601 and multiple sets of arc-shaped rods 602 facilitate the movement guidance of the sliding seat 402 after being subjected to auxiliary force.

[0022] Preferably, the reset assembly includes a mounting groove 701 formed on the sliding seat 402, a mounting rod 702 fixed inside the mounting groove 701, a lifting platform 403 slidably connected to the mounting rod 702, and a spring 703 fixed on the outside of the mounting rod 702. The two ends of the spring 703 are respectively abutted against the inner wall of the mounting groove 701 and the lifting platform 403. It should be noted that: the multiple sets of mounting rods 702 inside the mounting slot 701 guide the movement of the lifting platform 403 after being subjected to force, and the spring 703 facilitates the reset of the lifting platform 403 after the movement.

[0023] Preferably, the pushing assembly includes a push rod 801 fixed on the lifting platform 403, and the interior of the arc groove 601 is fixed with a plurality of hemispherical protrusions 802 for pressing against one end of the push rod 801. It should be noted that during the movement of the lifting platform 403 and the sliding seat 402, the push rod 801 moves synchronously. During the movement of the push rod 801, one end of the push rod 801 abuts against each set of hemispherical protrusions 802 in sequence. Through the pressing action of the hemispherical protrusions 802 against one end of the push rod 801, the lifting platform 403 is subjected to force and moves downward. During the downward movement of the lifting platform 403, the spring 703 is deformed and generates elastic force. When one end of the push rod 801 is no longer abutting against the hemispherical protrusions 802, the elastic force of the spring 703 causes the lifting platform 403 to return to its original position. Therefore, during the reciprocating swing of the lifting platform 403, through transmission, the lifting platform 403 moves up and down synchronously in the vertical direction and vibrates.

[0024] Preferably, the second mounting component includes multiple sets of slots 501 formed on the mounting plate 404 and the swing plate 202, and the slots 501 communicating between the mounting plate 404 and the swing plate 202 are connected by pins 502. It should be noted here that after the installation sleeve 201 is installed and limited, the swing piece 202 is installed. During the installation process, the slot 501 on the swing piece 202 is made to communicate with the slot 501 on the mounting plate 404, and the pin 502 is used for insertion and limitation to complete the installation of the swing piece 202.

[0025] Preferably, two sets of the first mounting components are provided on the mounting sleeve 201, and the two sets of the first mounting components are arranged symmetrically on the mounting sleeve 201; It should be noted here that the stability of the installation is ensured by using two sets of first installation components.

[0026] Preferably, the first mounting component includes a threaded hole 301 opened on the mounting sleeve 201, and a T-shaped threaded pin 302 is threadedly engaged on the threaded hole 301, with one end of the T-shaped threaded pin 302 abutting against the outer side of the airflow detection rod 105. It should be noted that during the use of the air volume measurement matrix, the swing-up component is pre-installed on the airflow detection rod 105 of the static pressure pipe 102. During installation, the mounting sleeve 201 is fitted onto the airflow detection rod 105. During the fitting process, the mounting sleeve 201 is moved to a suitable position by sliding on the airflow detection rod 105. As the mounting sleeve 201 moves, the T-shaped threaded pin 302 is rotated. During the rotation, the mutual meshing transmission between the T-shaped threaded pin 302 and the threaded hole 301 causes one end of the T-shaped threaded pin 302 to abut against the outer side of the airflow detection rod 105. Through the abutting and pressing action, the fitted and slidably adjusted mounting sleeve 201 is limited and fixed.

[0027] In this solution: an airflow matrix dust prevention device includes the following steps: During the use of the air volume measurement matrix, the swinging component is pre-installed on the airflow detection rod 105 of the static pressure pipe 102. During the installation process, the mounting sleeve 201 is fitted onto the airflow detection rod 105. During the fitting process, the mounting sleeve 201 is moved to a suitable position by sliding on the airflow detection rod 105. As the mounting sleeve 201 moves, the T-shaped threaded pin 302 is rotated. During the rotation process, the mutual meshing transmission between the T-shaped threaded pin 302 and the threaded hole 301 causes one end of the T-shaped threaded pin 302 to abut against the outer side of the airflow detection rod 105. Through the abutment and compression action, the fitted and slidably adjusted mounting sleeve 201 is limited and fixed. After the mounting sleeve 201 is installed and limited, the swinging plate 202 is installed. During the installation process, the slot 501 on the swinging plate 202 is connected to the slot 501 on the mounting plate 404 and the pin 502 is inserted and limited to complete the installation of the swinging plate 202. After the swing component is installed, along with the use of the air volume measurement matrix, the interaction between the turbulent flow field inside the air volume measurement matrix and the swing plate 202 causes the swing plate 202 to be subjected to force and move. During the process of the swing plate 202 being subjected to force, through the connection of the mounting plate 404, the lifting platform 403, the reset component and the sliding seat 402 and the sliding guide of the arc rod 602, the swing plate 202 is subjected to force and swings back and forth around the outside of the mounting ring 401 and collides with the mounting ring 401. During the collision process, through the connection between the mounting ring 401 and the mounting sleeve 201, the airflow detection rod 105 is driven to swing. Through the swing, dust and particles attached to the static pressure pipe 102 can be shaken off. In addition, the tiny airflow vortex generated by the swing can blow away the impurities accumulated near the static pressure pipe 102, preventing them from forming a dense blockage layer and achieving the dustproof effect. In addition, during the movement of the lifting platform 403 and the sliding seat 402, the push rod 801 moves synchronously. During the movement of the push rod 801, one end of the push rod 801 abuts against each set of hemispherical protrusions 802 in sequence. Through the pressing action of the hemispherical protrusions 802 against one end of the push rod 801, the lifting platform 403 is subjected to force and moves downward. During the downward movement of the lifting platform 403, the spring 703 is deformed by force and generates elastic force. When one end of the push rod 801 is no longer abutting against the hemispherical protrusions 802, the elastic force of the spring 703 causes the lifting platform 403 to return to its original position. Therefore, during the reciprocating swing of the lifting platform 403, through transmission, the lifting platform 403 moves up and down synchronously in the vertical direction and vibrates. Through reciprocating motion and vibration, the probability of foreign matter sticking to the surface of the swing plate 202 during use is reduced, which facilitates the efficient use of the swing plate 202.
