Description

Technical Field

[0001] This utility model relates to the field of environmental monitoring device technology, and in particular to an atmospheric environmental monitoring device. Background Technology

[0002] Accurate and efficient monitoring of air quality is crucial for timely understanding of pollution levels, formulating targeted environmental protection policies, and implementing effective pollution control measures. Air quality monitoring devices are required for these monitoring operations.

[0003] To prevent excessive dust accumulation and blockage at the air inlet of existing environmental monitoring devices during prolonged use, which would affect the operation of the air detectors, filters are often installed on the air inlet of the air inlet duct. However, these filters are mostly installed in a static and fixed manner, which makes it impossible to clean them thoroughly and effectively directly on the air inlet duct. They need to be removed from the air inlet duct before cleaning can be carried out, which is quite troublesome and inconvenient.

[0004] In addition, the structural optimization design of the air inlet duct is not reasonable enough, and most of them do not have rainproof function. As a result, when the detection device is used in rainy weather, rainwater can easily be guided to the air detector through the air inlet duct, causing the air detector to be waterlogged and burned. Utility Model Content

[0005] In view of this, the present invention provides an atmospheric environment detection device to solve the problem that the filter structure needs to be disassembled from the air inlet pipe for thorough and effective cleaning, which is cumbersome and inconvenient to operate.

[0006] The technical solution proposed by this utility model is: an atmospheric environment detection device, specifically including a control box, an air detector and two air inlet pipes, wherein the air inlet pipes are used to transport the outside air to be detected to the air detector;

[0007] The air inlet duct has a U-shaped continuous curved structure; two vertical positioning shafts are symmetrically welded to the top of the control box, and a U-shaped sliding frame that is reset by spring push is slidably installed on the two vertical positioning shafts. Two filter sleeves are symmetrically welded to both ends of the U-shaped sliding frame; a rectangular frame is welded to the bottom opening of the filter sleeve, and a metal filter screen is installed inside the rectangular frame. The filter sleeve slides in fit with the first end of the air inlet duct, and the rectangular frame abuts against the first end of the air inlet duct. The metal filter screen covers the opening at the first end of the air inlet duct; a T-shaped transmission component is welded to the bottom middle position of the rectangular frame; a horizontal mounting frame is welded to the lower half of the two vertical positioning shafts, and a drive shaft is rotatably installed through the middle part of the horizontal mounting frame. A drive rocker arm is welded to the first end of the drive shaft. When the drive rocker arm rotates with the drive shaft, its first end indirectly abuts against the horizontal base plate of the T-shaped transmission component.

[0008] Furthermore, an installation ring is welded to the top center of the inner side of the control box, and an air detector is fixedly installed at the top of the installation ring;

[0009] A vertical air duct is welded through the center of the top wall of the control box, and a conical air diffuser is welded to the bottom end of the vertical air duct. The air diffuser is directly opposite the air detector.

[0010] Furthermore, an axial flow fan is fixedly installed at the top of the vertical air guide pipe, and a circular air collection hood is fixedly connected to the top air intake of the axial flow fan. Two air inlet pipes are symmetrically welded to the top of the air collection hood.

[0011] Furthermore, a guide wheel is rotatably mounted at the head end of the drive lever, and the head end of the drive lever abuts against the horizontal base plate of the T-shaped transmission component through the guide wheel.

[0012] Furthermore, a Z-shaped rocker arm is welded to the tail end of the drive shaft.

[0013] Furthermore, a detection controller is wall-mounted on the lower half of the control box back panel, and the detection controller is communicatively connected to the air detector.

[0014] The control box has a cover that is rotatably mounted on its open side.

[0015] The atmospheric environment detection device provided by this utility model has the following beneficial effects:

[0016] 1. The U-shaped sliding frame is slidably installed on two vertical positioning shafts. By simply sliding the U-shaped sliding frame up and down along the two vertical positioning shafts, the rectangular frame at the bottom of the two filter sleeves can be driven to intermittently impact and contact the beginning of the two air inlet pipes. This vibrates and cleans the impurities intercepted and accumulated on the two metal filter screens. Compared with the existing technology of directly fixing the filter sleeve to the air inlet at the beginning of the air inlet pipe, this method can clean the metal filter screen at the bottom of the air inlet pipe directly on the air inlet pipe without removing the filter sleeve. This is convenient to operate and helps to improve the cleaning efficiency of the filter sleeve.

[0017] Second, by transmitting power through the horizontal base plate of the drive lever and the T-shaped transmission component, the simple action of rotating the drive shaft can drive the U-shaped sliding frame and the two filter sleeves to slide up and down repeatedly, thus performing impact vibration cleaning on the two filter sleeves. Compared with the design of directly cleaning the two filter sleeves by sliding the U-shaped sliding frame up and down by hand, this can save the trouble of frequent small up and down movements of the hand and help improve the convenience of filter sleeve cleaning operations.

[0037] Please refer to Figures 1 to 7 ; Example

[0038] This utility model proposes an atmospheric environment detection device, including a control box 1, an air detector 3 and two air inlet pipes 501. The air inlet pipes 501 are used to transport the outside air to be detected to the air detector 3.

[0039] The air inlet duct 501 has a U-shaped continuous bending structure; two vertical positioning shafts 105 are symmetrically welded to the top of the control box 1, and a U-shaped sliding frame 6, which is reset by spring push, is slidably installed on both vertical positioning shafts 105. Two filter sleeves 601 are symmetrically welded to both ends of the U-shaped sliding frame 6; a rectangular frame is welded to the bottom opening of the filter sleeve 601, and a metal filter screen is installed inside the rectangular frame. The filter sleeve 601 is slidably engaged with the first end of the air inlet duct 501, and the rectangular frame is engaged with the first end of the air inlet duct 501. The metal filter screen is sealed on the opening at the first end of the air inlet pipe 501. A T-shaped transmission component 602 is welded and hoisted at the bottom middle position of the rectangular frame. A horizontal mounting frame 1051 is welded to the lower half of the two vertical positioning shafts 105. A drive shaft 7 is rotatably mounted through the middle part of the horizontal mounting frame 1051. A drive rocker arm 701 is welded to the first end of the drive shaft 7. When the drive rocker arm 701 rotates with the drive shaft 7, its first end indirectly abuts against the horizontal base plate of the T-shaped transmission component 602.

[0040] Preferably, a mounting ring 102 is welded to the top center of the inner side of the control box 1, and an air detector 3 is fixedly installed at the top of the mounting ring 102; a vertical air guide pipe 103 is welded through the center of the top wall of the control box 1, and a conical air diffuser 104 is welded to the bottom of the vertical air guide pipe 103, with the air diffuser 104 facing the air detector 3 vertically.

[0041] Preferably, an axial flow fan 4 is fixedly installed at the top of the vertical air guide duct 103, and a circular air collection hood 5 is fixedly connected to the top air intake of the axial flow fan 4. Two air inlet pipes 501 are symmetrically welded to the top of the air collection hood 5.

[0042] Based on Example 1, Example 2:

[0043] A guide wheel is rotatably mounted at the head end of the drive rocker arm 701, and the head end of the drive rocker arm 701 abuts against the horizontal base plate of the T-shaped transmission component 602 through the guide wheel; a Z-shaped rocker arm 702 is welded to the tail end of the drive shaft 7; a detection controller 2 is wall-mounted on the lower half of the back panel of the control box 1, and the detection controller 2 is communicatively connected to the air detector 3; a box cover 101 is rotatably mounted on the open side of the control box 1.

[0044] It is worth noting that the model number of the air detector 3 is QL100HJXD, and the brand is Qiluo IoT.

[0045] The following is a detailed explanation and description of the specific details, implementation steps, functions and interrelationships of the above-mentioned features, and their roles in realizing this invention:

[0046] During testing, external air is drawn and transported by the axial flow fan 4, sequentially passing through two air inlet pipes 501, the air collection hood 5, the cylindrical shell of the axial flow fan 4, the vertical air guide pipe 103, and the air diffuser hood 104, and then blown onto the air detector 3 for detection. The axial flow fan 4 can draw and transport a large amount of external air to the air detector 3, allowing the air detector 3 to fully contact the external air for detection. This avoids the axial flow fan 4 being obscured and hidden in the control box 1, which would prevent it from fully receiving external air and affecting the detection accuracy.

[0047] The two air inlet pipes 501 have a continuous vertical bending structure, which has a blocking effect on rainwater. This can prevent rainwater from being directly drawn into and guided to the air detector 3 through the two air inlet pipes 501 without being blocked, causing the air detector 3 to be waterlogged and burned.

[0048] The two filter sleeves 601, through their two metal mesh screens at the top and bottom, can filter and intercept impurities in the air drawn into the two air inlet pipes 501, providing dustproof and anti-clogging protection for the air detector 3. The U-shaped sliding frame 6 is slidably installed on the two vertical positioning shafts 105. By simply sliding the U-shaped sliding frame 6 up and down along the two vertical positioning shafts 105, the rectangular frame at the bottom of the two filter sleeves 601 can be driven to intermittently impact and contact the beginning of the two air inlet pipes 501, thus vibrating and cleaning the impurities intercepted and accumulated on the two metal mesh screens. Compared with the existing technology of directly fixing the filter sleeves 601 to the air inlet at the beginning of the air inlet pipe 501, this allows for cleaning of the metal mesh screens at the bottom of the air inlet pipe 501 directly on the air inlet pipe 501 without disassembling the filter sleeves 601. This is convenient to operate and helps to improve the cleaning efficiency of the filter sleeves 601.

[0049] When the drive lever 701 follows the rotation of the drive shaft 7 and comes into contact with the horizontal base plate of the T-shaped transmission component 602, it can push and drive the T-shaped transmission component 602 and the U-shaped sliding frame 6 to slide downwards. When the drive lever 701 swings away from the horizontal base plate of the T-shaped transmission component 602, the compressed springs on the two vertical positioning shafts 105 can automatically push the U-shaped sliding frame 6 upwards to impact and slide. In this way, power is transmitted through the horizontal base plate of the drive lever 701 and the T-shaped transmission component 602. The simple action of rotating the drive shaft 7 can drive the U-shaped sliding frame 6 and the two filter sleeves 601 to slide up and down, performing impact vibration cleaning on the two filter sleeves 601. Compared with the design of directly cleaning the two filter sleeves 601 by sliding the U-shaped sliding frame 6 up and down by hand, this can save the trouble of frequent small up and down movements of the hand and help improve the convenience of cleaning the filter sleeves 601. The drive shaft 7 can be rotated by the Z-shaped rocker arm 702.

[0050] The working principle of this embodiment is as follows: During use, when external air is drawn in by the axial flow fan 4 and delivered to the air detector 3, the air detector 3 comes into contact with the external air to perform detection. When the air detector 3 detects the content of various impurities in the air, it transmits the content data to the detection controller 2. The detection controller 2 is remotely connected and communicates with the detection control center through a wireless communication module or wired communication. After receiving the content data, the detection controller 2 first compares and analyzes the data to determine whether the content of various impurities in the air exceeds the standard. Then, it displays the data and the alarm information for exceeding the standard on its built-in display screen and transmits it remotely to the detection control center. The information displayed on the screen of the detection controller 2 is for on-site personnel to view directly, while the information transmitted remotely is for personnel at the detection control center to view remotely.
