Description

Technical Field

[0001] This utility model relates to site defogging technology, and in particular to mobile airport defogging equipment. Background Technology

[0002] Air visibility is a key indicator for safe aircraft takeoff and landing at airports, and airport defogging is an important aspect of airport flight environment management. Traditional airport defogging technologies include several types such as electromagnetic fluid field defogging, acoustic defogging, airflow-driven defogging, and infrared high-altitude irradiation defogging.

[0003] Prior art ZL 2022106557507 discloses an airflow-driven airport defogging system, comprising: a mobile device, a three-electrode defogging device, and an airflow-driven charging device; the mobile device includes a flat plate and can move within the airport runway; more than three three-electrode defogging devices are mounted around the flat plate to form a multi-sided enclosed defogging space; the three-electrode defogging devices are used to generate a corona electric field through corona discharge during operation; and the airflow-driven charging device is disposed on the flat plate and located within the defogging space, used to generate an airflow from bottom to top within the defogging space and charge the fog flowing over its top; during operation, fog enters the defogging space from outside under the action of the airflow, and some fog is charged and collected under the action of the corona electric field when passing through the three-electrode defogging device, while the remaining fog is transported from bottom to top within the defogging space, charged at the top of the airflow-driven charging device, and then transported by the airflow to a distant location to collide with and condense with fog at a distance.

[0004] In practical use, the shortcomings of the above-mentioned technical solutions are mainly manifested in four aspects: First, the three-electrode fog-blocking device is fixedly installed on both sides of the airport runway, and can only intercept fog around the runway. Inside the runway, fog droplets are accelerated and condensed through sound wave oscillation, resulting in limited overall defogging efficiency. Second, the effective range of the defogging device is only within the area directly opposite the electrodes. It has high defogging efficiency in enclosed spaces, but in open spaces such as airport runways, the ion wind generated by the electrodes will dissipate to the surroundings, thus failing to achieve efficient defogging of the airport runway. In other words, it cannot operate in airport environments where rapid defogging is truly needed. Third, its operation generates electromagnetic interference to the environment, limiting the actual operable area within the airport. Fourth, it has high energy consumption. Summary of the Invention

[0005] The purpose of this utility model is to address the shortcomings of existing technologies by providing an airport defogging device that is simple in structure, has a wide operating area in the airport environment, and is energy-saving and environmentally friendly.

[0006] To achieve the above objectives, this utility model provides a mobile airport defogging device, the technical solution of which is as follows.

[0007] A mobile airport defogging device, characterized in that it comprises a moving part, a working part, and a power part, wherein the moving part drives the working part and the power part to move, and the power part supplies power to the moving part and the working part; the working part includes a fog-absorbing device, a defogging device, and a material regeneration device; the fog-absorbing device is connected to a rear defogging device through an air passage, and the fog-absorbing device includes an axial flow fan that guides fog into the air passage; the defogging device includes a chamber, and the chamber contains an adsorption component, which includes a photosensitive defogging material; the air passage connecting the fog-absorbing device opens at an air inlet on the chamber wall, and an exhaust outlet is opened on the opposite side of the chamber wall; the material regeneration device includes a light source inside the chamber.

[0008] The working principle of the aforementioned mobile airport defogging device is as follows: the moving part allows the device to be moved to the working area within the airport; the defogging device in the working part generates an intake airflow, drawing the fog into the device, where it flows around the adsorption components. The photosensitive defogging material quickly adsorbs the tiny water droplets contained in the fog, drying the surrounding airflow, and then discharges it from the outlet back into the environment. In non-defogging mode, the photosensitive defogging material is irradiated by a built-in light source, causing water molecules to quickly detach from the adsorption, regenerating the material and preparing it for the next round of defogging operations.

[0009] The aforementioned mobile airport defogging device can be further optimized. The following optimization schemes can be implemented individually or simultaneously without conflict.

[0010] Optimization 1: Add partitions to divide the space into compartments.

[0011] The partition divides the chamber into a demisting chamber and a regeneration chamber. The air inlet and exhaust outlet are located on two opposite sides of the chamber wall of the demisting chamber, and the light source is located in the regeneration chamber. A conveying mechanism is laid on the inner side of the chamber, which passes through the demisting chamber and the regeneration chamber. The adsorption components are fixed on the conveying mechanism. The conveying mechanism of the partition has a door at the point of passage, and the door size is not smaller than the opening size required for the adsorption components to pass through the partition.

[0012] Furthermore, the two partitions divide the chamber into three compartments: left, middle, and right, which are respectively a defogging chamber, a regeneration chamber, and a defogging chamber. Two ring-shaped conveying mechanisms are laid on the inner wall of the chamber, with each conveying mechanism passing through a defogging chamber and the adjacent side of the regeneration chamber. The light sources are arranged on the inner wall and / or inner top of the regeneration chamber and in the middle of the regeneration chamber. The light sources on the inner wall and / or inner top emit light from one side, while the light sources in the middle emit light from both sides.

[0013] Optimization 2: Improve the structure of the adsorption component to increase fog capture efficiency.

[0014] The adsorption assembly includes adsorption branches and a shaft. The adsorption branches are tree-shaped. The photosensitive defogging material is fixedly connected to the branches of the adsorption branches. The handles of the adsorption branches are fixedly connected to the shaft at a non-zero angle. The adsorption branches are distributed on the outer periphery of the shaft in a brush-like manner. The shaft is fixedly connected to the conveying mechanism at a non-zero angle.

[0015] Furthermore, the handle is rotatably coupled with the shaft, and the shaft is a rotating component; the shaft is rotatably coupled with the transmission mechanism, and the shaft is a rotating component.

[0016] Furthermore, the shaft is not fixedly connected to the conveying mechanism; the adsorption assembly also includes a frame, with multiple shafts arranged at intervals and fixedly connected to the inner sides of the frame at both ends to form a grid plate shape, the shafts and the frame are rotatably coupled, the shafts are rotating parts, and multiple frames are arranged at intervals and fixedly connected to the conveying mechanism at non-zero angles.

[0017] Optimization 3: Structural improvement of the material recycling device.

[0018] The material recycling device also includes a slope plate, which forms a slope below the conveying mechanism in the recycling chamber, and drainage holes are opened in the silo wall at the foot of the slope.

[0019] Furthermore, the material recycling device also includes a water collection tank connected to the rear side of the drainage hole, and a water channel is opened on the upper surface of the slope plate.

[0020] Fourthly, improvements were made to the structure of the moving part.

[0021] The main body of the moving part is the car body, which includes the frame and the steering mechanism. The lower part of the steering mechanism is fixedly connected to the frame, and the upper part is fixedly connected to the working part and the power part through the support platform.

[0022] Fifthly, improve the control performance of the device.

[0023] The mobile airport defogging device also includes a control unit, which includes a monitoring system. The monitoring system includes a central control unit, which is connected to an environmental monitoring unit, a work control unit, a movement control unit, a power control unit, a status signal unit, and a communication unit. The environmental monitoring unit collects environmental index data through sensors. The work control unit controls the work unit II, the movement control unit controls the movement unit I, the power control unit controls the power unit III, the status signal unit displays the working status signals, and the communication unit communicates with the outside world.

[0024] Compared with the prior art, the beneficial effects of this utility model are: (1) The mobile airport defogging device of this utility model uses special photosensitive defogging material as the core working component. Through the simple component combination, it realizes mobile defogging operation in the airport with extremely low energy consumption.

[0037] The preferred embodiments of the present invention will be further described below with reference to the accompanying drawings. Example 1

[0038] like Figure 1 As shown, a mobile airport defogging device is being fabricated.

[0039] Figure 1 This is a schematic diagram of a mobile airport defogging device, where the dashed arrows indicate the direction of airflow.

[0040] The mobile airport defogging device includes a moving part I, a working part II, and a power part III. The moving part I drives the working part II and the power part III to move, and the power part III supplies power to the moving part I and the working part II.

[0041] Working section II includes a fog-absorbing device 1, a defogging device 2, and a material regeneration device 3. The fog-absorbing device 1 is connected to the rear defogging device 2 through an air passage. The fog-absorbing device 1 includes an axial flow fan 11, which guides the fog into the air passage. The defogging device 2 includes a chamber 21, which contains an adsorption component 22. The adsorption component 22 includes a photosensitive defogging material 221. The air passage connecting the fog-absorbing device 1 opens at an air inlet 211 on the chamber wall, and an exhaust port 212 is opened on the opposite side of the chamber wall. The material regeneration device 3 includes a light source 31 inside the chamber 21.

[0042] In this example, ambient fog is guided into the fog-absorbing device 1 by the axial flow fan 11, and then enters the chamber 21 through the air passage and air inlet 211. Inside the chamber 21, water molecules in the fog are adsorbed and separated by the photosensitive defogging material 221, and the dry gas re-enters the environment through the exhaust port 212, completing the defogging process. During non-defogging periods, the light source 31 irradiates the photosensitive defogging material 221 to dehydrate it, thus regenerating the material.

[0043] Power unit III supplies power to moving unit I and working unit II (generally using external electrical power or batteries), which can be achieved using existing technologies in the field of electromechanical design.

[0044] In this example, the photosensitive defogging material 221 is specifically PAM-MXene, which is a hydrogel. To match the dehydration conditions of PAM-MXene, the light source 31 is specifically a xenon lamp. Example 2

[0045] like Figure 2 , Figure 3 As shown, a mobile airport defogging device is fabricated. The similarities with Embodiment 1 will not be repeated, but the difference lies in the structure of the defogging device.

[0046] Figure 2 This is a schematic diagram of the compartmentalized structure of the warehouse, where (a) shows the left and right compartments and (b) shows the upper and lower compartments.

[0047] The partition 213 divides the chamber 21 into a demisting chamber 214 and a regeneration chamber 215. The air inlet 211 and the exhaust outlet 212 are located on two opposite sides of the chamber wall of the demisting chamber 214. The light source 31 is located inside the regeneration chamber 215. A conveying mechanism 23 is laid on the inner side of the chamber 21. The conveying mechanism 23 passes through the demisting chamber 214 and the regeneration chamber 215. The adsorption component 22 is fixed on the conveying mechanism 23. The conveying mechanism 23 of the partition 213 passes through an opening door 2131. The size of the door 2131 is not smaller than the opening size required for the adsorption component 22 to pass through the partition 213.

[0048] By cooperating with the compartmentalized chamber and the conveying mechanism 23, the adsorption component 22 is partially in the defogging chamber 214 and partially in the regeneration chamber 215 at the same time. It can also alternate between cyclical (meaning the conveying mechanism 23 always transmits in one direction) and reciprocating (meaning the conveying mechanism 23 transmits back and forth), thus enabling simultaneous defogging and regeneration, improving defogging efficiency. Simultaneously, the compartmentalized chamber reduces the working space for defogging and regeneration, allowing the photosensitive defogging material 221 to have more sufficient contact with the fog or light.

[0049] The partition 213 can divide the compartment 21 into left and right or top and bottom sections.

[0050] Figure 3 This is a schematic diagram of a three-chamber chamber structure (one side of the adsorption component is omitted).

[0051] The chamber 21 is divided into three chambers—left, middle, and right—by two partitions 213, which are, in order, a defogging chamber 214, a regeneration chamber 215, and a defogging chamber 214. Two ring-shaped conveyor mechanisms 23 are installed on the inner wall of the chamber 21, with each conveyor mechanism 23 passing through an adjacent side of a defogging chamber 214 and a regeneration chamber 215. Light sources 31 are arranged on the inner wall and / or inner ceiling of the regeneration chamber 215, and in the middle of the regeneration chamber 215. The light sources 31 on the inner wall and / or inner ceiling emit light from one side, while the light sources 31 in the middle emit light from both sides.

[0052] The optimized three-chamber structure forms two demisting working groups, each including a demisting chamber 214, a conveying mechanism 23, and an adsorption component 22. The mist drawn in by the self-fogging device 1 enters one of the demisting working groups for drying. The two working groups share a regeneration chamber 215, and the adsorption component 22 can be irradiated from both sides during the light regeneration process. The three-chamber structure offers higher efficiency in both the demisting and regeneration stages. Example 3

[0053] like Figure 4 , Figure 5 As shown, a mobile airport defogging device is fabricated. The similarities with Example 2 will not be repeated here, but the difference lies in the structure of the adsorption component.

[0054] Figure 4 This is a schematic diagram of the adsorption component 22 (showing a roller brush shape).

[0055] The adsorption component 22 includes adsorption branches 222 and a shaft 223. The adsorption branches 222 are in the shape of tree branches. The photosensitive defogging material 221 is fixedly connected to the branches 2221 of the adsorption branches 222. The handles 2222 of the adsorption branches 222 are fixedly connected to the shaft 223 at a non-zero angle. The adsorption branches 221 are distributed on the outer periphery of the shaft 223 in the shape of a roller brush. The shaft 223 is fixedly connected to the conveying mechanism 23 at a non-zero angle.

[0056] The above structure can be augmented with a rotating design, where the handle 2222 is rotatably coupled to the shaft 223, making the handle 2222 a rotating component, and the shaft 223 is rotatably coupled to the conveying mechanism, making the shaft 223 a rotating component. Specifically, the handle 2222 can be connected to the shaft 223 via a rotary motor 225, with the handle 2222 fixedly connected to the rotor of the rotary motor 225; the shaft 223 can be connected to the conveying mechanism 23 via the rotary motor 225, with the shaft 223 fixedly connected to the rotor of the rotary motor 225.

[0057] Figure 5 This is a schematic diagram of the adsorption component 22 (showing a grid plate shape); Figure 6 This is a schematic diagram of one arrangement of the adsorption component 22 (grid plate shape).

[0058] Figure 5 The structure is Figure 4The structure is integrated, with arrows indicating relative rotation. Shaft 223 is not fixedly connected to conveying mechanism 23. The adsorption assembly 22 also includes frame 224. Multiple shafts 223 are arranged at intervals and fixedly connected to the inner sides of two opposite sides of frame 224 through both ends to form a grid plate. Shaft 223 and frame 224 are rotatably coupled. Shaft 223 is a rotating component. Multiple frames 224 are arranged at intervals and fixedly connected to conveying mechanism 23 at non-zero angles.

[0059] By utilizing rotational movement, the chances of fog droplets being captured by the photosensitive defogging material 221 can be increased, thereby improving defogging efficiency. Further enhancement of the effect is achieved by coordinating the movement of the adsorption component 22 via the lower conveying mechanism 23. Example 4

[0060] like Figure 7 As shown, a mobile airport defogging device is fabricated. The similarities with Example 3 will not be repeated here, except for the material regeneration device 3.

[0061] Figure 7 This is a schematic diagram of the components of the material recycling device.

[0062] The material recycling device 3 also includes a slope plate 32, which is located below the conveying mechanism 23 in the recycling chamber 215 to form a slope, and a drainage hole 2151 is opened in the chamber wall at the foot of the slope.

[0063] The material recycling device 3 also includes a water collection tank 33 connected to the rear side of the drain hole 2151, and a water channel 321 is opened on the upper surface of the slope plate 32. Example 5

[0064] like Figure 8 As shown, a mobile airport defogging device is fabricated. The similarities with Embodiment 4 will not be repeated, but the difference lies in the mobile part I.

[0065] Figure 8 This is a schematic diagram of the vehicle body structure 4.

[0066] The main body of the moving part I is the vehicle body 4, which includes wheels 41, a frame 42, and a steering mechanism 43. The lower part of the steering mechanism 43 is fixedly connected to the frame 42, and the upper part is fixedly connected to the working part II and the power part III through a support platform 431.

[0067] In this structure, both the working part II and the power part III are fixed on the support 431 of the steering mechanism 43, which can change the direction as a whole and adjust quickly, so that the fog suction device 1 is always in front of the defogging device, that is, in the "windward" position, to achieve low-energy air intake. Example 6

[0068] like Figure 9 As shown, a mobile airport defogging device is fabricated. The similarities with Embodiment 5 will not be repeated, but the difference lies in the control unit IV.

[0069] Figure 9 This is a schematic diagram of the monitoring system structure.

[0070] Control unit IV includes monitoring system 5, which includes central control unit 51. Central control unit 51 is connected to environmental monitoring unit 52, work control unit 53, movement control unit 54, power control unit 55, status signal unit 56, and communication unit 57. Environmental monitoring unit 52 collects environmental index data through sensors, work control unit 53 controls work unit II, movement control unit 54 controls movement unit I, power control unit 55 controls power unit III, status signal unit 56 displays work status signals, and communication unit 57 communicates with the outside world.

[0071] In this structure, the central control unit 51 can issue commands to the working control unit 53, the movement control unit 54, the power control unit 55, and the status signal unit 56 based on environmental indicators (such as visibility) collected by the environmental monitoring unit 52 and / or external communication commands received by the communication unit 57. The movement control unit 54 controls the movement direction and speed of the vehicle body 4 and the steering mechanism 53 to steer the vehicle, positioning the fog-absorbing device 1 in the "windward" position. The status signal unit 56 issues working start / stop status signals and warning signals for the fog-absorbing device. The central control unit 51 can directly use an Arduino series microcontroller (MCU).
