Description

Technical Field

[0001] The utility model is a damper device, in particular to an intelligent damper device with a flow guide component and pressure measurement function, which has stable exhaust when opened, high tightness when closed, and more accurate automatic detection of wind pressure, flow rate, flow rate, temperature, humidity, pH, gas concentration, etc. in the air duct. Background Art

[0002] Today, a damper is a device installed in ventilation ducts to control the flow of air. Specifically, it determines the amount of airflow passing through by setting the opening and closing of the valve structure. Figure 1A and Figure 1B As shown in the figure, it is a single-leaf valve damper of the prior art. It can be clearly seen from the figure that the internal channel of the damper 1 can allow air flow to pass through, including a valve 11, two detectors 12 and an orifice plate 13 arranged between the two detectors 12. The valve 11 is used to control the air flow, and the detector 12 is a unit with two groups P1 and P2. The two groups of detectors 12 are combined with an orifice plate 13 to calculate the pressure difference of the gas flowing into the orifice plate 13, so as to detect the values ​​of wind pressure, wind speed, wind volume, etc. However, the single-leaf valve damper of the prior art has the following problems to be overcome:

[0003] 1. Space Occupancy: When the valve is opened and tilted left or right, it takes up a large space.

[0004] 2. Unstable airflow: The left and right inclined leaf doors are difficult to control the flow rate because the opening area and the opening angle are not linearly proportional. In addition, the inclined leaf doors will easily cause backflow bubbles due to the airflow colliding with the wall and the corner, which will cause the airflow to flow in a disorderly manner and lead to poor exhaust.

[0005] 3. Lack of tightness: When the air duct and the valve have sufficient tightness, the valve will be stuck when opening and closing, making it difficult to open and close the valve and easy to damage. When the valve is easy to open and close, its tightness is insufficient, which can easily cause the exhaust gas to flow back.

[0006] 4. Disadvantages of wind pressure / wind speed measurement: The detectors installed may cause inaccurate measurement data due to unstable airflow in the air duct. If there are not enough detectors, balanced and stable values ​​cannot be obtained. If there are too many detectors, the fixed-point operation will be cumbersome and the large number of values ​​will lead to inaccurate calculations.

[0007] In order to solve the above problems, the prior art discloses a rainbow damper structure, which is applied to the ventilation duct of the blower and is arranged at the outer side of the inlet end of the blower, comprising: an oblate cylindrical outer shell, wherein an air inlet and an air outlet are respectively arranged at the central axis of the front and rear sides thereof to form a front-to-back through-channel for air circulation; and an adjustment plate and an iris blade group are stacked in sequence from the air inlet to the inside of the inner space of the outer shell, wherein the adjustment plate is an annular plate body, and a plurality of radial long slots are arranged in an annular manner at equal angles on the adjustment plate; the iris blade group is surrounded by a plurality of rainbow blades of equal shape, such as three or more, and has an annular switch function, wherein each blade is a curved arc-shaped sheet body, one end of which is a movable end, and a protrusion is provided on the top surface of the movable end to respectively slide with a corresponding long slot hole on the adjustment plate and can be driven to shift by the long slot hole, and the other end is a fixed end, and an opening is provided on the fixed end to respectively correspond to an opening on the rear side of the outer shell for positioning.

[0008] With the above structure, when the adjustment plate is rotated forward or reversely, the long slot holes can be used to drive the movable end protrusions of each blade of the iris blade group to move inward or outward, so that the movable ends of each blade move relatively inward or outward, thereby controlling the opening and closing degree of the rainbow damper formed by the blades; thereby, when the blower is running and the air passes through the rainbow damper, the opening and closing degree of the rainbow damper is controlled to change the air flow rate, so that the rainbow damper achieves the effect of simple structure, quick operation, easy installation and easy control of the blower inlet air volume.

[0009] However, this structure does not have an automatic control function, and the blades are of a linked design, using only a long slot hole to cooperate with the shaft rod for opening and closing. If the operation is improper, the entire damper set may be damaged, and it is impossible to replace a single component blade for the damaged part. Furthermore, the linked design limits the opening and closing aperture, resulting in an excessively large opening aperture after closing, making it difficult to achieve a tight fit.

[0048] Preferably, the toothed disc 222 further includes a large gear 2222, a small gear 2223 and a motor 2224. The large gear 2222 is disposed on the outer wall of the toothed disc 222. The small gear 2223 is disposed on the edge of the toothed disc 222 and meshes with the large gear 2222. The motor 2224 is connected to the small gear 2223 for driving.

[0051] The gate 22 further includes a gear position detector 227 connected to the main control system 26 for controlling the switch of the motor 2224 and detecting the rotation position of the large gear 2222 and the small gear 2223 .

[0052] The air inlet pipe 23 is connected to one end of the gate 22, and includes an inner tube 232 and an outer tube 233 arranged outside the inner tube 232. The outer wall of the outer tube 233 has an outer ring 2331, and the wall of the inner tube 232 corresponding to the top of the outer ring 2331 has at least one differential pressure air inlet hole 241.

[0054] Preferably, the plurality of detectors 212 are further disposed on the wall of the air outlet pipe 21 and extend into the air outlet pipe 21 to detect the air flow inside the air outlet pipe 21 .

[0055] The plurality of detectors 25 and 212 are wind pressure detectors, flow rate detectors, flow rate detectors, temperature detectors, humidity detectors, pH detectors, or gas concentration detectors, but are not limited thereto.

[0056] The intelligent damper device of the present invention further includes a disaster prevention device (not shown) connected to the main control system 26 for taking corresponding measures according to the detected conditions.

[0057] Based on the above structure and composition design, the use and operation of the present invention are described as follows: the main control system 26 is connected to the plurality of detectors 25, and the main control system 26 can receive the data transmitted by the plurality of detectors 25. Further, the data transmitted by the plurality of detectors 25 can be processed and analyzed, and if the data exceeds the threshold, the main control system 26 can issue an abnormal warning. The main control system 26 can also be set in the cloud, and the plurality of detectors 25 transmit the data to the main control system 26 by wireless means, and the present invention does not limit the transmission method.

[0058] See also FIG. 5A to FIG. 6C , which illustrates that the gate blade 225 of the utility model is individually movable, and both ends of the plurality of gate blades 225 are respectively fixed to the positioning point 2221 through the positioning shaft 2251, and the movable shaft 2252 is placed in the movable groove 2211. The movable shaft 2252 can move in the movable groove 2211 to make the plurality of gate blades 225 open or close the gate 22. Since the gate blade 225 is assembled as individual blades, if the blade or the axis is damaged, it is convenient to replace and repair a single component.

[0059] See also 7A to 8B , illustrates the guide member 226 of the utility model, which is arranged at the center of the plurality of gate blades 225, and includes a shuttle-shaped guide 2261. Due to the advantages of the shuttle shape, the curvature is small and the smoothness is high. When the plurality of gate blades 225 are closed, they can fit with the guide member 226 to achieve a close fit effect. It can also achieve a fairing-like function and guide the wind direction smoothly. Compared with the traditional "ball-shaped" guide, the curvature is larger, and the above-mentioned effects are inferior to the "shuttle-shaped" guide.

[0060] See also Fig. 9, which explains that the air inlet duct 23 of the utility model is different from the conventional air door which adopts a single-group detection method. When the discharged gas enters the air duct, it first flows to the air collecting chamber 24 in the differential pressure air inlet hole 241 set in the outer ring 2331, and the detector 25 measures the wind pressure and other data and reports it to the main control system 26. Then the gas enters through the full-pressure air inlet hole 2263, flows through the full-pressure air outlet pipe 2264, and the detector 25 measures the wind pressure and other data and reports it to the main control system 26. With this design, the utility model can measure more accurately.

[0061] Preferably, the main control system 26 further includes a gate control module (not shown) and a processing module (not shown), wherein the gate control module is configured in the main control system 26 to receive data transmitted by the plurality of detectors 25, and issue an abnormal warning according to the detection conditions to control the motor 2224 to close or open the gate, wherein the processing module receives the data transmitted by the plurality of detectors 25 to construct a flow characteristic fitting curve, and according to the flow characteristic fitting curve to determine to send a control signal to the gate control module to control the opening degree of the gate 22, thereby adjusting the gas flow rate of the ventilation duct.

[0062] To further explain, the information provided by the complex detector 26 is processed by the processing module through the least square method, conjugate gradient method or regression analysis method to construct a numerical model of the flow characteristic fitting curve. When the user sets a predetermined flow, the main control system 26 uses the flow characteristic fitting curve to send a corresponding control signal to the gate control module to control the opening degree of the gate 22, thereby adjusting and measuring the gas flow rate of the ventilation duct. The information provided by the complex detector 26 can be used to feedback and correct the opening degree of the gate 22 to provide a stable flow and meet the set flow requirements, so as to achieve the purpose of feedback control.

[0063] Furthermore, the utility model includes a main control system 26, which is connected to the plurality of detectors 25, the motor 2224 and the gear positioning detector 227, for receiving the data transmitted by the plurality of detectors 25, and issuing an abnormal warning according to the detection status, and for controlling the motor 2224 to open or close the gate 225. For example, an automatic opening and closing mechanism of the abnormal warning gate 22, an abnormal warning alarm mechanism, and an automatic opening mechanism of the abnormal warning disaster prevention monitoring equipment can be achieved. Pre-disaster prevention can be achieved by disaster prevention equipment such as automatic cooling equipment; automatic watering, foam, water mist, carbon dioxide, dry powder and other equipment.

[0065] The plurality of detectors 25 are disposed at the other end of the differential pressure outlet pipe 242 and the total pressure outlet pipe 2264. With this arrangement, there is no need to dispose components such as the outer ring 2331 and the air collection chamber 24 as in the previous embodiment.

[0066] It should be particularly noted that the air collection chamber 24 of the utility model can be set at one of the gate 22, the flow guide member 226, the air inlet pipe 23, and the air outlet pipe 21, and the air collection chamber 24 includes a differential pressure air inlet hole 241 and a differential pressure air outlet pipe 242, and the plurality of detectors 26 are set at the differential pressure air outlet pipe 242 and at the other end of the total pressure air outlet pipe 2264 for detection. By flexibly setting the air collection chamber 24 at different positions, it is possible to determine where the pressure difference is to be detected according to needs, thereby achieving more flexible and precise control.

When air flows in from the differential pressure air inlet 241 and flows out through the differential pressure air outlet pipe 242, the detector 26 can detect it.
