Description

Technical Field

[0001] This utility model relates to a de-icing fluid collection and treatment system for de-icing pads, belonging to the field of airport ground cleaning technology. Background Technology

[0002] Winters in northern regions are cold and snowy, and ice, snow, and frost on aircraft surfaces can affect their dynamic performance. To ensure safe flight, airports in northern regions typically have de-icing pads for pre-flight de-icing. De-icing fluid is a liquid sprayed onto the aircraft surface to reduce the adhesion between ice and the aircraft surface or lower the freezing point of water on the aircraft surface, thus achieving the purpose of de-icing. Commonly used de-icing fluids include ethylene glycol, propylene glycol, and organic acids. De-icing wastewater needs to be properly disposed of to avoid environmental impact and harm. This invention is a facility installed on the de-icing pad for convenient collection of de-icing fluid.

[0003] Common methods for collecting and disposing of de-icing fluid include: direct discharge of waste fluid into the flight area drainage system; collection by recovery vehicles; and setting up de-icing fluid interception ditches on the de-icing pad to collect waste fluid before discharging it into a waste fluid collection pool. Direct discharge makes de-icing fluid recovery difficult, collection by recovery vehicles is inefficient, and setting up interception ditches involves a large amount of engineering work and is costly; none of these methods achieve a simple, quick, and convenient recovery of de-icing fluid. Summary of the Invention

[0004] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a de-icing fluid collection and treatment system for de-icing pads. The system uses an interception and guidance method to collect de-icing waste fluid and guide it into a designated area such as a waste fluid collection pool or a separate waste fluid drainage system. The system is simple in design, easy to construct, and convenient to use.

[0005] To achieve the above objectives, this utility model employs the following technical solution:

[0006] In a first aspect, this utility model provides a de-icing fluid collection and treatment system for a de-icing pad, including an interception screen and a collection pool installed on a de-icing pad with a certain slope. The interception screen includes multiple longitudinal and transverse interception screens arranged in a row, wherein the longitudinal interception screens are all located at the bottom of the transverse slope of the de-icing pad, and the transverse interception screens are all located at the bottom of the longitudinal slope of the de-icing pad. A gap is provided at the angle between the longitudinal and transverse interception screens, and the collection pool is located in the gap. The interception screen includes two stainless steel plates, and the two stainless steel plates are rotatably connected by stainless steel connectors. One of the stainless steel plates is fixed to the surface of the de-icing pad by a fastener. The back of the stainless steel plate is covered with a layer of polyvinyl chloride (PVC) isolation cloth, and the upper and lower ends of the PVC isolation cloth are fixed to the stainless steel plate by fasteners. Each PVC isolation cloth covers the gap between two adjacent stainless steel plates.

[0007] Furthermore, the top of the collection pool is open, and a flip-open top cover is provided at the opening. The top cover includes a reinforced concrete top cover and a stainless steel top cover, and the stainless steel top cover and the reinforced concrete top cover are rotatably connected.

[0008] Furthermore, the surface of the reinforced concrete top cover is provided with a liquid extraction well cover and an exhaust hole.

[0009] Furthermore, the stainless steel plate has a thickness of 3mm, and the stainless steel plate standing upright on the de-icing surface has a height of 0.5m.

[0010] Furthermore, the height difference between the top surface of the collection pool and the apron is 0.01m, and the horizontal distance is 1m.

[0011] Furthermore, the collection pool has a depth of 2.5m, a length and width of 5m, and a wall thickness of 200mm.

[0012] Furthermore, the longitudinal and transverse slopes of the de-icing apron are both 1%.

[0013] Compared with the prior art, the beneficial effects achieved by this utility model are as follows:

[0014] I. This solution can effectively prevent de-icing waste liquid from being discharged outside the apron, playing an interception and guidance role, and avoiding the need to excavate trenches on the de-icing apron, reducing construction difficulty and project cost. The relatively long stainless steel plate can be folded and flat-laid on the apron in spring, summer and autumn, which is convenient for the use of the apron and improves the visual effect.

[0015] II. This solution improves the seepage prevention effect by adding polyvinyl chloride (PVC) isolation cloth. During use, the PVC isolation cloth is fixed to the outside of the stainless steel plate with fasteners. It can be washed and stored in spring, summer and autumn and used in winter.

[0016] 3. In this scheme, the surface of the reinforced concrete top cover is provided with a liquid extraction well cover and an exhaust hole. The liquid extraction well cover is used to extract the de-icing fluid in the collection tank, while the exhaust hole is to ensure that the air pressure in the collection tank can be consistent with the outside air pressure after the stainless steel top cover is closed, so as to ensure that the de-icing fluid can be extracted smoothly.

[0023] The present invention will now be described in detail with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described herein can be combined with each other.

[0024] The following detailed description is exemplary and intended to provide further detailed explanation of the present invention. Unless otherwise specified, all technical terms used in this invention have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used in this invention is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to this invention.

[0025] Example:

[0026] Please refer to a de-icing fluid collection and treatment system for de-icing pads. Figure 1The system includes interceptor screens and collection pool 5 installed on the de-icing apron. It should be noted that, according to civil aviation regulations, the slope of the de-icing apron should meet the site drainage requirements and be able to collect de-icing and anti-icing fluid left from the aircraft. The maximum longitudinal slope of the de-icing parking area should be gentle, while the transverse slope should have a larger gradient, but the single-sided slope should not exceed 1%, and the double-sided slope symmetrical to the aircraft axis should not exceed 1.5%. In this implementation, both the transverse and longitudinal slopes of the de-icing apron are sloped by 1%. Multiple interceptor screens are arranged in a row at the bottom of the transverse and longitudinal slopes, perpendicular to the slope direction and tightly fitted together, serving to block and divert the de-icing fluid. The two interceptor screens at the bottom of the transverse and longitudinal slopes are relatively perpendicular, with a gap at the angle between the two perpendicular screens, where the collection pool 5 is located. The de-icing machine is positioned at a location with a higher slope than the interceptor screen. When the de-icing fluid is sprayed onto the de-icing machine apron, due to the slope of the apron, the de-icing fluid flows obliquely downward along the direction between the transverse and longitudinal slopes of the apron under the action of gravity. The de-icing fluid that first flows to the interceptor screen will flow along the interceptor screen towards the collection pool 5, thus completing the collection of the de-icing fluid.

[0027] Please see Figure 2 In this embodiment, the interception screen includes two stainless steel plates 1, one long and one short, connected by a stainless steel connector 2. The two plates 1 can be rotated and folded via the connector 2. The shorter stainless steel plate 1 is fixed to the surface of the de-icing apron by a fixing member 3. In this embodiment, the stainless steel connector 2 serves both connecting and folding functions. During spring, summer, and autumn, the longer stainless steel plate 1 can be folded flat on the apron via the connector 2 for convenient use. The longer stainless steel plate 1 can stand vertically during de-icing, effectively blocking and diverting the de-icing fluid. Figure 2 In this system, the relatively long stainless steel plate 1 is in direct contact with the de-icing fluid on its front side. However, due to gaps between the multiple stainless steel plates 1 arranged in a row, a layer of polyvinyl chloride (PVC) isolation cloth 4 is placed on the back of the stainless steel plate 1 to prevent a small amount of de-icing fluid from leaking out along these gaps. The upper and lower ends of the PVC isolation cloth 4 are fixed to the stainless steel plate 1 by fasteners 3. It should be noted that each PVC isolation cloth 4 covers the gaps between the stainless steel plates 1, effectively preventing de-icing fluid from leaking out along these gaps. The stainless steel plate 1 is placed upright on the de-icing pad at a height of 0.5m. The stainless steel plate 1 is positioned on the downhill side to intercept the de-icing waste fluid discharged there and guide it to the collection tank 5 according to the apron slope. The fasteners 3 are metal parts welded to the stainless steel plate 1, which can fix the PVC isolation cloth 4 and the relatively short stainless steel plate 1. The PVC isolation cloth 4 acts as an anti-seepage barrier. It is fixed to the stainless steel plate 1 by the fasteners 3. In spring, summer, and autumn, it can be washed and recycled for storage, and reused in winter.

[0028] Please see Figure 3-4 The collection pool 5 is located at a certain height below the apron and at a certain distance from the apron. In this embodiment, the height difference between the top surface of the collection pool 5 and the apron is 0.01m, the horizontal distance is 1m, the depth of the collection pool 5 is 2.5m, the length and width are both 5m, and the wall thickness is 200mm. The top of the collection pool 5 is open, and a flip-open top cover is provided at the opening. In this embodiment, the top cover includes a reinforced concrete top cover 6 and a stainless steel top cover 7, and the stainless steel top cover 7 can be flipped open and closed towards the reinforced concrete top cover 6. When the stainless steel top cover 7 is open, de-icing fluid can flow in along the top opening of the collection pool 5. During non-de-icing seasons, the stainless steel top cover 7 is closed to prevent debris from falling into the collection pool 5. The surface of the reinforced concrete top cover 6 is provided with a liquid extraction well cover 8 and an exhaust hole 9. The liquid extraction well cover 8 is used to extract the de-icing fluid in the collection tank 5, while the exhaust hole 9 is to ensure that the air pressure in the collection tank 5 can be kept consistent with the outside air pressure after the stainless steel top cover 7 is closed, so as to ensure that the de-icing fluid can be extracted smoothly.

[0029] In summary, this solution effectively prevents de-icing wastewater from being discharged outside the apron, acting as an interceptor and guide, and avoiding the need to excavate trenches on the de-icing pad, thus reducing construction difficulty and project costs. The relatively long stainless steel plate 1 can be folded and laid flat on the apron during spring, summer, and autumn, facilitating its use and improving its visual appeal. The addition of a PVC isolation cloth 4 enhances the seepage prevention effect. During use, the PVC isolation cloth 4 is fixed to the outside of the stainless steel plate 1 using fasteners 3. It can be washed and stored during spring, summer, and autumn for use in winter.
