Description

TECHNICAL FIELD

[0001] The present invention is a kind of damper device, especially for opening the exhaust stability, the closure of high tightness, and has more accurate automatic detection of wind pipe wind pressure, flow rate, flow, temperature, humidity, pH, gas concentration and other functions with the guide member pressure measuring intelligent damper device. BACKGROUND

[0002] Now, the damper is a device installed on the ventilation duct to control air flow, specifically, it determines the size of the air flow by setting the opening and closing of the valve structure. Please refer to Figure 1A and Figure 1B The prior art single blade valve damper. As can be clearly seen from the figure, the internal passage of the damper 1 for air flow includes a valve 11, two detectors 12 and a orifice plate 13 arranged between the two detectors 12. The valve 11 is used to control air flow, and the two detectors 12 are calculated as a unit of two groups P1, P2, and the pressure difference of the gas flowing into the orifice plate 13 is calculated to detect the values of wind pressure, wind speed and air volume. However, the prior art single blade valve damper has the following problems to be overcome: 1. Space occupation: the left and right inclined valve must occupy a large space.

[0003] 2. Unstable air flow: the left and right inclined valve, because the opening area and the opening angle are not linearly proportional, the flow control is difficult, and the inclined valve will be easily caused by air flow collision wall and wall angle resistance, causing backflow bubble, making the air flow direction disorder and leading to smooth exhaust.

[0004] 3. Lack of tightness: when the damper is tightly closed, the valve will be tightly closed, causing the valve to open and close, and easily damaged. When the valve is easily opened and closed, the tightness is insufficient, which easily causes the backflow of the exhaust gas.

[0005] 4. Wind pressure / flow rate measurement defects: the detector is set due to unstable air flow in the duct, which easily causes inaccurate measurement data, and if the detector is insufficient, it cannot obtain balanced and stable values, and if the detector is too much, it will have the defects of tedious point application and inaccurate calculation due to more values.

[0006] To solve the above problems, the prior art discloses a rainbow damper structure applied to a ventilation duct of a blower and arranged at an inlet end outside of the blower, comprising: a flat cylindrical housing body, a wind inlet and a wind outlet are arranged at the center axes of the front and rear sides of the housing body respectively to form a channel for air flow through the front and rear sides; and the internal space of the housing body is sequentially stacked with an adjusting plate and a rainbow blade group from the wind inlet inward, wherein the adjusting plate is an annular plate body, a plurality of radial long slot holes are arranged on the adjusting plate at equal angles; the rainbow blade group is surrounded by a plurality of rainbow blades with equal shapes, such as three or more than three, to have a ring-shaped opening and closing function, wherein each blade is a curved arc-shaped plate body, one end of which is a movable end, a protrusion is arranged on the top surface of the movable end to correspondingly slide and fit into a long slot hole on the adjusting plate and can be driven to move by the long slot hole, and the other end is a fixed end, an opening is arranged on the fixed end to correspondingly fit into an opening on the rear side of the housing body to be positioned.

[0007] With the above structure, when the adjusting plate is rotated forward or reversely, the movable end protrusion of each blade of the rainbow blade group can be driven to move inward or outward by the long slot hole, so that the movable end of each blade moves inward or outward, thereby controlling the opening degree of the rainbow damper surrounded by the blades; in this way, when the blower operates and air passes through the rainbow damper, the opening degree of the rainbow damper is controlled to change the air flow, so that the rainbow damper achieves the use effect of simple structure, rapid operation, convenient installation and simple control of the inlet air volume of the blower.

[0008] However, this structure does not have an automatic control function, and the blades are designed in a linkage manner, only one long slot hole is used to cooperate with a shaft rod to perform opening and closing actions, improper operation can easily cause damage to the entire damper, and a single element blade cannot be replaced for the damaged part, and the linkage design limits the opening and closing aperture, resulting in a large opening aperture after closing, which is difficult to achieve a tight fit effect.

[0033] Please refer to Figure 4 The plurality of detectors 25 are arranged on the differential pressure outlet pipe 242 and the other end of the full-pressure outlet pipe 2264 for detection.

[0036] The intelligent air door device further includes a disaster prevention device (not shown in the figure) connected to the main control system 26, which can make corresponding treatment according to the detection condition.

[0037] Through the above structure, composition design, the use of the invention is 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 it exceeds the threshold value, 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 data to the main control system 26 through wireless means, and the present application does not limit the transmission method.

[0038] Please refer to Figures 5A to 6C , it is illustrated that the gate leaves 225 are individual blades, and the two ends of the plurality of gate leaves 225 are fixed to the positioning points 2221 through the positioning shafts 2251, and the movable shafts 2252 are inserted into the movable grooves 2211, and the movable shafts 2252 can move in the movable grooves 2211 to open or close the gate 22. Since the gate leaves 225 are individually assembled, if the blade or shaft is damaged, the single component can be replaced and repaired.

[0039] Please refer to Figures 7A to 8B , it is illustrated that the flow guide member 226 of the present application is arranged at the center position of the plurality of gate leaves 225, and includes a shuttle-shaped flow guide 2261. Due to the advantages of the shuttle-shaped design, the curvature is small and the flow is smooth. When the plurality of gate leaves 225 are closed, they can be attached to the flow guide member 226 to achieve a tight fit. It can also achieve the function of a fairing, guiding the wind direction smoothly. Compared with the traditional "ball-shaped" flow guide, the curvature is larger, and the above-mentioned effects are inferior to the "shuttle-shaped" flow guide.

[0040] Please refer to Figure 9 , it is illustrated that the air inlet pipe 23 of the present application is different from the single detection method of the known air door. When the discharged gas enters the air inlet pipe, it first flows to the differential pressure air inlet hole 241 of the outer ring 2331, and the data such as air pressure is measured by the detector 25, and the main control system 26 is returned. Then the gas enters through the full pressure air inlet hole 2263, flows through the full pressure air outlet connector 2264, and the data such as air pressure is measured by the detector 25, and the main control system 26 is returned. Through the design, the present application can be more accurate.

[0041] Preferably, the main control system 26 further comprises a gate control module (not shown) and a processing module (not shown). The gate control module is configured in the main control system 26 to receive the data transmitted by the plurality of detectors 25 and to send an abnormality warning according to the detection condition to control the motor 2224 to close or open the gate 22. The processing module receives the data transmitted by the plurality of detectors 25 to construct a flow characteristic fitting curve and to send a control signal to the gate control module according to the flow characteristic fitting curve to control the opening degree of the gate 22 to adjust the gas flow rate of the ventilation duct.

[0042] Further, the data provided by the plurality of detectors 26 is processed by the processing module to construct a numerical model of the flow characteristic fitting curve by using a data fitting algorithm such as the least square method, the conjugate gradient method or the regression analysis method. When a user sets a predetermined flow rate, the main control system 26 sends a corresponding control signal to the gate control module according to the flow characteristic fitting curve to control the opening degree of the gate 22 to adjust the gas flow rate of the ventilation duct. The opening degree of the gate 22 can be corrected by using the data provided by the plurality of detectors 26 to provide a stable flow rate and to meet the set flow rate requirement to achieve the purpose of feedback control.

[0043] Further, the present application comprises a main control system 26 connected to the plurality of detectors 25, the motor 2224 and the gear position detector 227 to receive the data transmitted by the plurality of detectors 25 and to send an abnormality warning according to the detection condition and to control the motor 2224 to open or close the gate 22. For example, the abnormality warning can be used to achieve an automatic opening mechanism of the gate 22, an alarm mechanism, an automatic opening mechanism of a disaster prevention monitoring device. The disaster prevention device such as an automatic cooling device, an automatic sprinkling device, a bubble device, a water mist device, a carbon dioxide device, a dry powder device and the like can be used to achieve the purpose of disaster prevention.

The wind collecting chamber 24 is provided with a differential pressure inflow hole 241 at one end.

[0045] The plurality of detectors 25 are disposed at the other end of the differential pressure outlet pipe 242 and the full pressure outlet pipe 2264. With this arrangement, there is no need to dispose the outer ring 2331, the air collection chamber 24 and other components as in the previous embodiment.

[0046] It should be noted that the air collection chamber 24 of the present invention can be located at one of the gate 22, the flow guide member 226, the air inlet pipe 23, or the air outlet pipe 21. The air collection chamber 24 includes a differential pressure air inlet 241 and a differential pressure air outlet pipe 242. Detection is performed by the plurality of detectors 26 located at the differential pressure air outlet pipe 242 and at the other end of the total pressure air outlet pipe 2264. By flexibly arranging the air collection chamber 24 in different locations, the pressure differential can be detected as needed, thereby achieving more flexible and precise control.

When air enters the differential pressure air inlet 241 and flows out through the differential pressure air outlet pipe 242, it can be detected by the detector 26.

[0048] In a preferred embodiment, if Figure 12 As shown, the air collecting chamber 24 is arranged inside the shuttle-shaped guide 2261, and a full-pressure air outlet pipe 2264 and a differential-pressure air outlet pipe 242 pass through the inside of the shuttle-shaped guide 2261. One end of the full-pressure air outlet pipe 2264 has a full-pressure air inlet hole 2263, and one end of the differential-pressure air outlet pipe 242 is connected to the air collecting chamber 24, and the other end has a differential-pressure air inlet hole 241.
