Description

Technical Field

[0001] The utility model relates to the technical field of measuring devices, and particularly relates to an anti-blocking air volume measuring device installed in a vertical air duct. Background Art

[0002] In modern industry and ventilation systems, the measurement of air volume in vertical air ducts is crucial. An anti-blocking air volume measuring device installed in a vertical air duct has emerged. This device is mainly used to accurately measure the air flow in the vertical air duct and provide key data support for the optimized operation of the ventilation system and energy management.

[0003] Traditional air volume measuring devices are prone to being blocked by dust in vertical air ducts, thus affecting the accuracy and stability of measurement. The air flow in vertical air ducts usually carries a large amount of dust and particulate matter, which are easily accumulated at the inlet of the measuring device to block the measuring probe, resulting in inaccurate measurement data or even inability to measure. Moreover, the existing air volume measuring devices are not convenient for centralized collection and treatment of dust, having certain deficiencies. Therefore, an anti-blocking air volume measuring device installed in a vertical air duct is needed to solve the above technical problems. Summary of the Utility Model

[0004] The purpose of the utility model is to make up for the deficiencies of the existing technology and provide an anti-blocking air volume measuring device installed in a vertical air duct.

[0005] To achieve the above purpose, the utility model provides the following technical solution: an anti-blocking air volume measuring device installed in a vertical air duct, including an air duct body. An installation frame is arranged at the top of the air duct body. A fixing piece is threadedly connected inside the installation frame. A bearing frame is fixedly connected to the inner wall of the installation frame. A measuring device body is fixedly installed on the inner wall of the bearing frame. A cleaning mechanism is arranged inside the bearing frame. A filter plate is fixedly installed at the bottom of the bearing frame. A limiting component is arranged inside the bearing frame. A sealing door is inserted into the inner wall of the bearing frame. A dust collection groove is formed inside the bearing frame.

[0006] Preferably, the cleaning mechanism includes a motor fixedly installed on the inner wall of the bearing frame. The output end of the motor is fixedly connected with a reciprocating lead screw, and the reciprocating lead screw rotates with the inner wall of the bearing frame.

[0007] Preferably, a moving frame is threadedly connected to the outside of the reciprocating lead screw. A cleaning brush is fixedly installed on the outer surface of the moving frame, and the cleaning brush contacts the filter plate.

[0008] Preferably, a limiting rod is slidably connected to the inner wall of the moving frame, and both ends of the limiting rod are fixed to the inner wall of the bearing frame.

[0009] Preferably, the limiting component includes two rotating shafts, the two rotating shafts are rotatably connected to the inner wall of the bearing frame, a connecting piece is fixedly connected to one end of each of the two rotating shafts close to each other, and a baffle is fixedly connected to the outer surface of the connecting piece.

[0010] Preferably, an elastic member is sleeved on the outer surface of each rotating shaft, one end of the elastic member is fixedly connected to the inner wall of the bearing frame, and the other end of the elastic member is fixedly connected to the outer surface of the connecting piece. The elastic member is a torsion spring.

[0011] Advantageous effects:

[0012] Compared with the prior art, the anti-blocking air volume measuring device installed in the vertical air duct has the following advantageous effects:

[0013] First, by setting the filter plate, the dust can be blocked. By setting the cleaning mechanism, the dust accumulated on the filter plate can be cleaned. By setting the limiting component and the dust collecting groove, the cleaned dust can be guided and stored. Through the mutual cooperation of the filter plate, the cleaning mechanism, the limiting component and the dust collecting groove, the dust can be conveniently collected and processed centrally, avoiding the situation that the measuring device body is blocked by dust and making the measurement data more accurate.

[0014] Second, by applying pressure to the baffle, the baffle drives the connecting piece and the rotating shaft to rotate around the rotating shaft as the axis. At the same time, the connecting piece presses the elastic member, causing it to generate elastic deformation and store a certain amount of elastic potential energy. When the pressure on the baffle is released, the elastic member releases the elastic potential energy, and then drives the connecting piece to rotate in the reverse direction. At the same time, the connecting piece drives the baffle to rotate in the reverse direction, thus realizing the rapid reset effect of the baffle. Description of the drawings

Detailed implementation mode

[0020] The principles and features of the present utility model will be described below with reference to the accompanying drawings. The examples given are only for explaining the present utility model and are not intended to limit the scope of the present utility model.

[0021] As Figures 1 to 4 shown, an anti-blocking air volume measuring device installed in a vertical air duct includes an air duct body 1, and a mounting frame 2 is arranged at the top of the air duct body 1. The mounting frame 2 is arranged in a concave shape and can be sleeved on the top of the air duct body 1, so as to realize the preliminary limiting effect on the mounting frame 2.

[0022] A fixing piece 3 is threadedly connected inside the mounting frame 2. The fixing piece 3 is composed of a screw rod and an extrusion piece. Rotating the screw rod can drive the extrusion piece to rotate, and then drive the extrusion piece to move close to the outer surface of the air duct body 1. When the extrusion piece abuts against the air duct body 1, the mounting frame 2 and the air duct body 1 can be fixed. A bearing frame 4 is fixedly connected to the inner wall of the mounting frame 2, and a measuring device body 5 is fixedly installed on the inner wall of the bearing frame 4.

[0023] A cleaning mechanism 6 is arranged inside the bearing frame 4. The cleaning mechanism 6 includes a motor 601 fixedly installed on the inner wall of the bearing frame 4. The output end of the motor 601 is fixedly connected with a reciprocating lead screw 602, and the reciprocating lead screw 602 rotates with the inner wall of the bearing frame 4. A moving frame 603 is threadedly connected to the outside of the reciprocating lead screw 602. A cleaning brush 604 is fixedly installed on the outer surface of the moving frame 603, and the cleaning brush 604 is in contact with the filter plate 7. The bottom of the cleaning brush 604 is closely attached to the filter plate 7, so as to improve the cleaning effect on dust. A limiting rod 605 is slidably connected to the inner wall of the moving frame 603, and both ends of the limiting rod 605 are fixed to the inner wall of the bearing frame 4.

[0024] When the motor 601 is turned on, the motor 601 will drive the reciprocating lead screw 602 to rotate at this time, and then the reciprocating lead screw 602 will drive the cleaning brush 604 to move close to the baffle 803. At this time, the cleaning brush 604 will scrape the dust on the top of the filter plate 7.

[0025] A filter plate 7 is fixedly installed at the bottom of the bearing frame 4. A limiting component 8 is arranged inside the bearing frame 4.

[0026] The limiting component 8 includes two rotating shafts 801 rotatably connected to the inner wall of the carrier 4. The rotating shafts 801 enable the connecting piece 802 and the baffle 803 to rotate around the rotating shafts 801, thereby achieving the limiting effect on the connecting piece 802 and the baffle 803. One connecting piece 802 is fixedly connected to each end of the two rotating shafts 801 close to each other, and a baffle 803 is fixedly connected to the outer surface of the connecting piece 802. A resilient member 804 is sleeved on the outer surface of each rotating shaft 801. The resilient member 804 is a torsion spring, and when its end is stressed, the whole resilient member 804 will undergo torsional deformation, thereby enabling the resilient member 804 to store a certain amount of elastic potential energy. After the stress disappears, the elastic potential energy will be released, which will drive the object at the movable end to rotate in the reverse direction for resetting. One end of the resilient member 804 is fixedly connected to the inner wall of the carrier 4, and the other end of the resilient member 804 is fixedly connected to the outer surface of the connecting piece 802.

[0027] By applying pressure to the baffle 803, the baffle 803 drives the connecting piece 802 and the rotating shaft 801 to rotate around the rotating shaft 801 as the axis. At the same time, the connecting piece 802 applies pressure to the resilient member 804, causing it to undergo elastic deformation and store a certain amount of elastic potential energy. When the pressure on the baffle 803 is released, the resilient member 804 will release the elastic potential energy, which will drive the connecting piece 802 to rotate in the reverse direction. At the same time, the connecting piece 802 will drive the baffle 803 to rotate in the reverse direction accordingly, thus achieving the rapid reset effect of the baffle 803.

[0028] A sealing door 9 is inserted into the inner wall of the carrier 4. A sealing gasket is provided on the outer surface of the sealing door 9 in contact with the carrier 4 to prevent dust from leaking. An inward concave snap groove is provided on the sealing door 9, which facilitates the operator to pull out the sealing door 9 from the inner wall of the carrier 4. A dust collection groove 10 is formed inside the carrier 4.

[0029] Working principle: When the utility model is in use, the mounting bracket 2 can be placed on the top of the air duct body 1. At this time, the mounting bracket 2 is sleeved on the outer side of the top of the air duct body 1, and then the fixing member 3 is rotated to fix between the mounting bracket 2 and the air duct body 1. When the fluid inside the air duct body 1 blows towards the measuring device body 5, the filter plate 7 will block the dust in the fluid. When the dust accumulates more, it will gradually move upward through the pores in the filter plate 7. When the dust accumulates for a long time, the dust will be impacted by the fluid to the top of the filter plate 7. At this time, the cleaning mechanism 6 can scrape and clean the dust. Specifically, the motor 601 needs to be started. At this time, the motor 601 will drive the reciprocating screw rod 602 to rotate, and then the reciprocating screw rod 602 will drive the cleaning brush 604 to move close to the baffle 803. At this time, the cleaning brush 604 will scrape the dust on the top of the filter plate 7. When the cleaning brush 604 contacts the baffle 803, it will exert pressure on the lower end of the baffle 803, so that the baffle 803 drives the connecting piece 802 and the rotating shaft 801 to rotate around the rotating shaft 801 as the axis. At the same time, the connecting piece 802 will exert pressure on the elastic member 804, causing it to generate elastic deformation and store a certain amount of elastic potential energy. At this time, the dust will fall into the dust collection groove 10, and then the reciprocating screw rod 602 will drive the moving frame 603 and the cleaning brush 604 to move away from the baffle 803, so as to gradually relieve the pressure on the baffle 803. At this time, the elastic member 804 will release the elastic potential energy, which will drive the connecting piece 802 to rotate in the reverse direction. At the same time, the connecting piece 802 will drive the baffle 803 to rotate in the reverse direction, thus realizing the rapid reset effect of the baffle 803, making the baffle 803 re-close the dust collection groove 10. Finally, the dust in the dust collection groove 10 can be taken out by pulling open the sealing door 9 to realize the centralized treatment of the dust. Through the mutual cooperation of the filter plate 7, the cleaning mechanism 6, the limiting component 8 and the dust collection groove 10, it is convenient to collect and treat the dust centrally, avoiding the situation that the measuring device body 5 is blocked by dust and making the measurement data more accurate.

[0030] The above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included in the protection scope of the present utility model.
