Description

Technical Field

[0001] This utility model belongs to the field of airport ecological environment monitoring technology, and in particular relates to a dust concentration detection device for ecological environment monitoring. Background Technology

[0002] Airports are large open-air environments, and aircraft takeoffs, landings, and taxiing generate dust. Excessive dust can affect flight safety. Therefore, it is necessary to install dust concentration detection devices in airports to monitor the concentration of particulate matter in the air in real time, assess the impact of dust on aircraft engines and navigation systems, and ensure that the flight environment meets safety standards.

[0003] Chinese patent CN221976690U discloses a dust concentration detection device for ecological environment monitoring. The device includes a chassis and a vertical pole. The vertical pole is fixed to the top of the chassis, and an extension rod is longitudinally arranged above the vertical pole. Insert blocks are fixed to both ends of the bottom of the extension rod, and screws are threaded into the insert blocks. Splicing grooves are provided at both ends of the top of the vertical pole. This dust concentration detection device for ecological environment monitoring solves the problem of device position fixation by using a collar fitted around the outside of the vertical pole, splicing the extension rod and vertical pole according to installation requirements, tightening screws after inserting the insert blocks into the splicing grooves, holding the collar and moving it along a longitudinal slide. The pulley installed inside the collar rolls along the longitudinal slide during movement, providing lubrication. Then, fastening bolts are used to lock and fix the device in place. Finally, the tilted chassis is straightened and fixed to the ground.

[0004] However, the above scheme is not convenient to adjust the wind speed and temperature according to the actual situation. In airport environmental monitoring, the passive air intake is very unstable due to the take-off and landing of aircraft or in strong winds. At the same time, in winter, the low temperature will affect the accuracy of the detection device. Therefore, it is necessary to design a dust concentration detection device for ecological environment monitoring. Utility Model Content

[0007] Preferably, the heating tube is spirally wound around one side of the surface of the detection tube, and the inner wall of the heating sleeve is provided with a heat insulation layer.

[0008] Preferably, the adjusting assembly includes: a vertical rod disposed on one side of the collecting cylinder, wherein bolt holes are equally spaced on one side of the surface of the vertical rod; a sliding seat slidably connected to the surface of the vertical rod, wherein one side of the sliding seat is fixedly connected to the surface of the collecting cylinder, and a fixing bolt extending into the interior of the sliding seat is movably connected to one side of the sliding seat, wherein one end of the fixing bolt and the interior of the bolt hole form a threaded engagement structure.

[0009] Preferably, a limiting plate is welded to one side of the surface of the vertical rod, and a limiting groove is provided on the inner wall of the sliding seat to slide and cooperate with the limiting plate.

[0010] Preferably, the mounting assembly includes: mounting grooves symmetrically formed at the lower end of the inner wall of the collecting cylinder; a fixing groove formed at the bottom end of the sealing plate, wherein mounting plates are symmetrically slidably connected inside the fixing groove, one end of the mounting plates extends to the outside of the fixing groove, and a lever extending to the outside of the sealing plate is fixedly connected to one side of the bottom end of the mounting plates; and a mounting spring fixedly connected between one end of the two mounting plates.

[0014] Preferably, the inner wall of the ash collection hopper is funnel-shaped, and the lower end of the surface of the ash collection hopper is inclined.

[0015] Compared with related technologies, the dust concentration detection device for ecological environment monitoring provided by this utility model has the following beneficial effects: By using a wind speed sensor to detect the intake air rate, when the rate is too fast or too low, the intake area of ​​the opening on one side of the intake disc is changed by a solenoid valve. At the same time, the operation of the micro variable frequency fan can change the intake air volume, thereby realizing the regulation of the intake air volume to cope with sudden changes in wind pressure. Furthermore, a temperature sensor can be used to detect the intake air temperature. When the intake air temperature is too low in winter, the heating element can be activated to heat the inside of the detection tube, thereby avoiding the impact of low temperature or unstable intake air volume on the accuracy of the dust concentration detector. This ensures that the dust concentration detector can accurately detect the dust concentration in the airport environment, improving its practicality.

[0016] The installation components allow for quick assembly and disassembly of the sealing plate and the bottom of the collection cylinder, enabling the filter cylinder to be quickly removed and the collected dust and other impurities to be centrally processed. During installation, the upper and lower sealing rings can be used to improve the sealing between the upper end of the inner wall of the filter cylinder and the lower end of the surface of the dust collection hopper, as well as the opening between the outer surface of the filter cylinder and the lower end of the inner part of the collection cylinder, avoiding the cumbersome and inconvenient traditional assembly and disassembly of the filter cylinder.

The terms "first," "second," etc., in the specification, claims, or foregoing drawings of this application are used to distinguish different objects, not to describe a particular order.

[0020] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments. Example

[0021] A preferred embodiment of the dust concentration detection device for ecological environment monitoring provided by this utility model is, for example... Figures 1 to 6As shown: A dust concentration detection device for ecological environment monitoring includes a collection cylinder 1; an adjustment component 7 mounted on one side of the collection cylinder 1, which is used to achieve sliding adjustment of the collection cylinder 1 at different heights; a miniature variable frequency fan 6 fixedly connected to the lower end of one side of the collection cylinder 1; a dust collection hopper 10 fixedly connected to the upper end of the inner wall of the collection cylinder 1; a sealing plate 12 provided at the bottom end of the collection cylinder 1; a filter cylinder 9 fixedly connected to the top end of the sealing plate 12; an installation component 8 mounted on the sealing plate 12, which is used to achieve quick assembly and disassembly of the filter cylinder 9; a detection tube 3 fixedly connected to the upper end of one side of the collection cylinder 1; a dust concentration detector body 2 fixedly connected to one side of the top end of the detection tube 3; a heating sleeve 11 fixedly connected to the surface of the detection tube 3 on one side of the dust concentration detector body 2; a heating tube 15 provided inside the heating sleeve 11; a wind speed sensor 17 and a temperature sensor 16 fixedly connected to the inner wall of the detection tube 3 on one side of the heating sleeve 11; an air inlet plate 5 fixedly connected to one end of the detection tube 3; and a solenoid valve 4 provided on the surface of the detection tube 3 on one side of the air inlet plate 5.

[0022] It should be noted that some existing dust concentration detection devices for ecological and environmental monitoring still have certain shortcomings in actual use. In airport environmental monitoring, the passive air intake is very unstable due to aircraft take-off and landing or strong winds. At the same time, in winter, the low temperature will affect the detection accuracy of the device.

[0023] In this embodiment, the limiting plate 704 is installed and fixed at a suitable location in the airport. Then, the height of the collection cylinder 1 from the ground is adjusted to a suitable position using the adjusting component 7 and then fixed. An external power supply is then connected, and the micro-frequency converter fan 6 is started, creating negative pressure inside the collection cylinder 1. This draws in external air through the detection tube 3 and the air intake plate 5. The wind speed sensor 17 detects the air intake rate. If the rate is too high, the air intake area on one side of the air intake plate 5 is reduced via the solenoid valve 4; conversely, if the rate is too high, the air intake area is increased. Simultaneously, the operation of the micro-frequency converter fan 6 can change the intake air volume, thereby achieving air volume regulation to cope with sudden changes in wind pressure. Furthermore, the temperature sensor 16 can detect the temperature of the incoming air, especially in winter. When the inlet air temperature is too low, the heating tube 15 can be activated to heat the inside of the detection tube 3, thereby avoiding the impact of low temperature or unstable airflow on the accuracy of the dust concentration detector body 2. At the same time, dust and other impurities after the airflow is inlet are filtered through the filter cartridge 9, causing dust and other impurities to accumulate inside the filter cartridge 9. During subsequent routine maintenance, the limiting fixation of the sealing plate 12 can be released by the installation component 8, and then the filter cartridge 9 can be removed through the sealing plate 12 for easy handling of dust and other impurities inside the filter cartridge 9. During installation, the upper sealing ring 13 and the lower sealing ring 14 can be used to improve the sealing between the upper end of the inner wall of the filter cartridge 9 and the lower end of the surface of the dust collection hopper 10, and between the outer surface of the filter cartridge 9 and the lower end of the inner opening of the collection cylinder 1.

[0024] In a further preferred embodiment of the present invention, the heating tube 15 is spirally wound around one side of the surface of the detection tube 3, and the inner wall of the heating sleeve 11 is provided with a heat insulation layer.

[0025] In this embodiment, the use of a spirally wound heating tube 15 facilitates more uniform heating of the inside of the detection tube 3.

[0026] In a further preferred embodiment of the present invention, the adjusting component 7 includes: a vertical rod 701 disposed on one side of the collecting cylinder 1, with bolt holes 705 evenly spaced on one side of the surface of the vertical rod 701; a sliding seat 703 slidably connected to the surface of the vertical rod 701, one side of the sliding seat 703 being fixedly connected to the surface of the collecting cylinder 1, and a fixing bolt 702 extending into the interior of the sliding seat 703 being movably connected to one side of the sliding seat 703, with one end of the fixing bolt 702 forming a threaded engagement structure with the interior of the bolt hole 705.

[0027] In this embodiment, the sliding seat 703 slides on the surface of the vertical rod 701, and the fixed bolt 702 is engaged with the thread inside the bolt hole 705 to achieve the limiting and fixing of the sliding seat 703 after sliding on the surface of the vertical rod 701. This allows the height of the collecting cylinder 1 from the ground to be changed, so that dust concentration can be detected according to the actual situation.

[0028] In a further preferred embodiment of the present invention, a limiting plate 704 is welded to one side of the surface of the vertical rod 701, and a limiting groove 706 is provided on the inner wall of the sliding seat 703 to slide and cooperate with the limiting plate 704.

[0029] In this embodiment, the sliding between the limiting plate 704 and the limiting groove 706 allows the sliding seat 703 to slide smoothly up and down, but it cannot rotate on the surface of the vertical rod 701. Example

[0030] Based on Example 1, a preferred embodiment of the dust concentration detection device for ecological environment monitoring provided by this utility model is as follows: Figures 1 to 6 As shown: The mounting assembly 8 includes: mounting grooves 802 symmetrically formed at the lower end of the inner wall of the collecting cylinder 1; fixing grooves 807 formed at the bottom end of the sealing plate 12, mounting plates 801 symmetrically slidably connected inside the fixing grooves 807, one end of the mounting plates 801 extending to the outside of the fixing grooves 807, and a lever 805 extending to the outside of the sealing plate 12 fixedly connected to one side of the bottom end of the mounting plates 801; and mounting springs 804 fixedly connected between one end of the two mounting plates 801.

[0031] In this embodiment, by moving the lever 805, the mounting plate 801 slides inside the fixing groove 807, compressing the mounting spring 804 until it is completely disengaged from the mounting groove 802. Then, the lever 805 pulls down the sealing plate 12, allowing the filter cartridge 9 to be removed from the collection cylinder 1 for centralized processing of dust and other impurities collected inside the filter cartridge 9. During installation, the filter cartridge 9 is inserted into the collection cylinder 1, and the lever 805 is released. The elastic force of the mounting spring 804 causes the mounting plate 801 to slide and engage with the mounting groove 802, ensuring a firm and stable engagement between the sealing plate 12 and the bottom of the collection cylinder 1.

[0032] In a further preferred embodiment of the present invention, one end of the mounting plate 801 and the interior of the mounting groove 802 form an engaging structure, and the two sides of the bottom end of the collecting cylinder 1 are arc-shaped.

[0033] In this embodiment, the arc-shaped collecting cylinder 1 is used to facilitate the locking and fixing of the sealing plate 12 with the bottom end of the collecting cylinder 1.

[0034] In a further preferred embodiment of the present invention, a sliding groove 806 is provided on the inner wall of the fixing groove 807, and a slider 803 that slides and engages with the inside of the sliding groove 806 is fixedly connected to both sides of one end of the mounting plate 801.

[0035] In this embodiment, the sliding of the slider 803 and the inside of the groove 806 is used to improve the smoothness of the sliding of the mounting plate 801.

[0036] In a further preferred embodiment of this utility model, an upper sealing ring 13 is fixedly connected to the lower end of the surface of the ash collection hopper 10, and a lower sealing ring 14 is fixedly connected to the lower end of the surface of the filter cylinder 9. The upper sealing ring 13 and the lower sealing ring 14 are O-shaped.

[0037] In this embodiment, the upper sealing ring 13 and the lower sealing ring 14 are used to improve the sealing between the upper end of the inner wall of the filter cylinder 9 and the lower end of the surface of the ash collection hopper 10, as well as the outer surface of the filter cylinder 9 and the lower end of the inner opening of the collection cylinder 1.

[0038] In a further preferred embodiment of the present invention, the inner wall of the ash collection hopper 10 is funnel-shaped, and the lower end of the surface of the ash collection hopper 10 is inclined.

[0039] In this embodiment, a funnel-shaped dust collection hopper 10 is used to allow dust and other impurities to fall more smoothly and in a concentrated manner into the interior of the filter cartridge 9.

[0040] In summary, by using solenoid valve 4, micro variable frequency fan 6, heating tube 15, temperature sensor 16 and wind speed sensor 17, the air intake volume inside detection tube 3 and the temperature inside detection tube 3 can be adjusted. This can avoid the instability of air intake volume or the low temperature affecting the detection accuracy of dust concentration detector body 2. At the same time, the installation component 8 can be used to realize the quick engagement and disengagement between sealing plate 12 and bottom end of collection cylinder 1, which facilitates the disassembly and cleaning of filter cylinder 9.
