Description

Technical Field

[0001] The invention relates to the technical field of civil aviation ground support, in particular to a novel aircraft deicing pad. Background Art

[0002] The current aircraft de-icing pads are all built in the same way as ordinary aprons. A drainage ditch is set up on the periphery of the de-icing pad to collect de-icing waste liquid. A collection pool is set up downstream of the drainage ditch. An openable and closable gate is set between the collection pool and the drainage ditch to control the diversion of rainwater and de-icing waste liquid. When de-icing in the ice and snow season, the downstream valve of the drainage ditch is closed, and the valve of the de-icing liquid collection pool is opened to allow the de-icing waste liquid to flow into the collection pool for collection; in the non-ice and snow season, the valve of the de-icing liquid collection pool is closed, and the downstream drainage ditch valve is opened to allow rainwater to be discharged to the outside of the field through the drainage ditch.

[0003] The applicant has found that the prior art has at least the following technical problems: 1. Slow deicing wastewater confluence speed: Due to the large deicing area, a Class C stand occupies an area of ​​about 4000m 2 , an E-class stand covers an area of ​​about 6600m 2 A fixed deicing apron generally has 4-5 positions, combining Class C and Class E, with a total area of ​​about 20,000-30,000 square meters. Even if a drainage ditch is set in the center, the confluence area is 10,000-20,000 square meters, and the confluence path is long. In addition, the main component of deicing waste liquid is ethylene glycol, which has lower fluidity than general rainwater after mixing with snow water, resulting in slow flow rate of waste liquid, large confluence area, and low collection efficiency. If the residue of deicing waste liquid stays on the pavement for a long time, it will cause a certain degree of erosion to the pavement.

[0004] 2. The capacity of the de-icing fluid collection pool is limited and it occupies a large space: Since the collection pool is independent of the de-icing pad, most of the de-icing fluid collection pools are small in size and volume due to space limitations. During the peak de-icing period in the ice and snow season, de-icing waste liquid is prone to overflow, eroding the surrounding road surface and polluting the surrounding soil or water. In addition, the collection pool is independent of the de-icing pad and has insufficient volume, resulting in the need for de-icing waste liquid collection vehicles to frequently collect and process de-icing waste liquid during aircraft de-icing operations. Secondly, the collection pool is located in a densely populated vehicle operation area near the de-icing position, and there are problems with the location design, resulting in a large conflict between the de-icing vehicle and the de-icing waste liquid collection vehicle on the operation path. It is impossible to take into account the de-icing waste liquid treatment work while de-icing the aircraft, affecting the efficiency of the de-icing operation.

[0005] 3. Rainwater and sewage are not separated, which is easy to pollute the environment: De-icing waste liquid and rainwater use the same drainage ditch, which is essentially a combination of rainwater and sewage. Although the drainage ditch can be cleaned, it is difficult to clean it because the drainage ditch is generally small in size and most of them are reinforced concrete box culverts. If the cleaning is not in place, the waste liquid residue will be discharged outside the airport with the rainwater and enter the municipal rainwater pipe network or the river outside the airport, thereby polluting the water and soil outside the airport.

[0006] For example, application number CN201020550215.8 discloses a centralized de-icing device for aircraft at the end of a runway, and application number CN201921612861.X discloses an airport de-icing recovery fluid regeneration device.

[0007] In summary, the design of de-icing waste liquid collection in the existing aircraft de-icing pad has technical bias. Limited by the design ideas, the design of the traditional apron mainly focuses on the parking, take-off and landing of aircraft, ignoring the collection and treatment of de-icing waste liquid, and can only open drainage ditches on the periphery of the aircraft de-icing pad. At the same time, the awareness of environmental protection is relatively weak, and there is a lack of sufficient understanding and attention to the environmental pollution problems that may be caused by de-icing waste liquid, and the structure of the apron itself has not been fully utilized to optimize the collection and treatment of de-icing waste liquid.

[0008] In view of this, the present invention is proposed. Summary of the invention

[0009] The purpose of the present invention is to provide a new aircraft deicing pad to solve the technical problems that the existing aircraft deicing pad design in the prior art has defects, ignores the collection and treatment of deicing waste liquid, leads to a long confluence path, slow confluence speed, low collection efficiency, and high environmental pollution risk. The preferred technical solutions among the many technical solutions provided by the present invention can produce many technical effects as described below.

[0024] To make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be described in detail below. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other implementation methods obtained by ordinary technicians in this field without creative work belong to the scope of protection of the present invention.

[0025] like Figure 1-Figure 5 As shown, the present invention provides a new aircraft deicing pad, including a deicing pad body 1, which includes a top plate 11 and a collection pool 12; the top plate 11 is located above the collection pool 12, and the top plate 11 is inclined downward from the four sides toward the middle, and is provided with a plurality of water collection holes 111 for connecting to the collection pool 12; the bottom plate of the collection pool 12 is inclined along the width direction of the aircraft 4, and a water collection pit 14 is provided at its lowest end.

[0026] In the prior art, the aircraft 4 de-icing pad relies on opening drainage ditches on its periphery to collect de-icing waste liquid, which has a slow convergence speed and low efficiency, causing the waste liquid to stay on the pavement for a long time and erosion of the pavement.

[0027] The present invention makes full use of the structural characteristics of the de-icing pad itself, and uses the top plate 11 of the de-icing pad body 1 not only as the main bearing surface for carrying the aircraft 4 for de-icing operations, but also shortens the convergence path of the de-icing waste liquid by tilting downward from the four sides to the middle, increases the convergence speed of the de-icing waste liquid, reduces the retention time of the waste liquid on the pavement, and thus reduces the erosion of the pavement. In addition, a number of water collection holes 111 are provided on the top plate 11, which are connected to the collection pool 12, so that the waste liquid can quickly flow into the collection pool 12 through the top plate 11 and will not be retained on the pavement. The bottom plate of the collection pool 12 is tilted along the width direction of the aircraft 4 to form a natural slope to guide the waste liquid to flow in the collection pool 12 and converge into the sump 14 at the lowest end, which is convenient for subsequent waste liquid discharge and treatment.

[0028] Furthermore, the number of the deicing platform bodies 1 includes one or more, which can be flexibly adjusted according to actual needs. Multiple deicing platform bodies 1 can be arranged in parallel to meet the use requirements in different scenarios.

[0029] As an optional implementation, Figure 2 , Figure 3 , Figure 4As shown, the water receiving holes 111 are arranged in a matrix on the top plate 11 , the diameter of the water receiving holes 111 is 5 cm-8 cm, and the distance between the centers of two adjacent water receiving holes 111 is 5 cm-15 cm.

[0030] This arrangement can ensure effective collection of waste liquid while minimizing the impact on the structural strength of the top plate 11, so that while the top plate 11 is bearing normal loads, the waste liquid can quickly and effectively enter the collection tank 12 through its slope setting and the water collection holes 111.

[0031] Furthermore, the distribution area of ​​the water collection holes 111 on the top plate 11 is arranged corresponding to the area of ​​the collection pool 12 below, so that the waste liquid flowing in through the water collection holes 111 can directly fall into the collection pool 12, thereby realizing efficient collection and treatment of the waste liquid.

[0032] As an optional implementation, Figure 3 , Figure 4 As shown, the thickness of the top plate 11 is 400 mm-500 mm, and the slopes of the top plate 11 in the length direction of the aircraft 4 and in the width direction of the aircraft 4 are both 0.6%-0.8%.

[0033] The specifications of the top plate 11 can be designed according to different types of aircraft 4. For example, the top plate 11 suitable for type E aircraft has a length of 80 m and a width of 70 m. The top plate 11 suitable for type C aircraft has a length of 45 m and a width of 40 m.

[0034] The thickness of the top plate 11 is 400 mm-500 mm, so that the top plate 11 has a good bearing capacity to meet the requirements of parking and de-icing operations of the aircraft 4 .

[0035] The slope of the top plate 11 is 0.6%-0.8%, which can increase the confluence speed of the waste liquid and reduce the retention time of the waste liquid on the road surface, thereby reducing the erosion effect on the top plate 11.

[0036] As an optional implementation, Figure 3 , Figure 4 As shown, the slope of the bottom plate in the length direction of the aircraft 4 and the width direction of the aircraft 4 is 1%-3%.

[0037] This arrangement can guide the waste liquid to flow faster in the collection tank 12 and converge into the sump 14 at the lowest end, thereby improving the efficiency of waste liquid treatment.

[0038] As an optional implementation, Figure 3 , Figure 4 , Figure 5 As shown, a guide wall 13 is provided in the collection pool 12, one end of the guide wall 13 is connected to the top plate 11, and the other end is connected to the bottom plate, and the guide wall 13 is alternately arranged in sequence along the width direction of the aircraft 4 to form an S-shaped flow path.

[0039] In the prior art, the collection pool is independent of the de-icing pad and has the problem of insufficient volume, which results in the need for a de-icing waste liquid collection vehicle to frequently collect and process the de-icing waste liquid during the aircraft de-icing operation. Secondly, the collection pool is located in a densely populated area near the de-icing station, and there are problems with the location design, resulting in a large conflict between the de-icing vehicle and the de-icing waste liquid collection vehicle on the operation path, making it impossible to take into account the de-icing waste liquid treatment work while performing aircraft de-icing operations, affecting the de-icing operation efficiency.

[0040] The present invention sets the collection pool 12 below the top plate 11, making full use of the space below the de-icing pad, increasing the capacity of the collection pool 12, and not occupying the space outside the de-icing pad. Since the collection pool has a large enough capacity, the de-icing waste liquid can be temporarily stored during the aircraft de-icing operation. Therefore, during the aircraft de-icing operation, there is no need to consider the treatment of the de-icing waste liquid. Subsequently, the de-icing waste liquid is treated after the flight is suspended, which solves the operational conflict between the two from the time dimension.

[0041] The size and volume of the collection pool 12 can be designed according to the use requirements to achieve an efficient operation mode of "ensuring the de-icing operation during sailing time and treating the de-icing waste liquid after suspension of sailing".

[0042] The size and volume of the collection pool 12 may also be further increased according to the actual operation of the airport to meet the deicing waste liquid storage needs for continuous operation for multiple working days.

[0043] The diversion wall 13 is provided to guide the flow of waste liquid by forming an S-shaped flow path, so as to extend the flow path of waste liquid in the collection tank 12, evenly distribute the waste liquid flow, and better converge it to the sump 14. Moreover, the diversion wall 13 also serves as a reinforcement structure, connecting the top plate 11 and the bottom plate of the collection tank 12 into a whole, so as to support the top plate 11, improve the structural strength of the top plate 11, and further improve the bearing capacity and stability of the deicing platform body 1.

[0044] As an optional implementation, the depth of the collecting pool 12 is 3m-5m, the thickness of the side wall of the collecting pool 12 is 400mm-500mm, the thickness of the bottom plate of the collecting pool 12 is 800mm-1200mm; the thickness of the guide wall 13 is 600mm-800mm, and the distance between two adjacent guide walls 13 is 3m-5m.

[0045] The depth of the collecting pool 12 is 3m-5m, the thickness of the side wall of the collecting pool 12 is 400mm-500mm, and the thickness of the bottom plate of the collecting pool 12 is 800mm-1200mm. This arrangement increases the capacity of the collecting pool 12 while improving the structural stability and bearing capacity of the collecting pool 12.

[0046] The thickness of the guide wall 13 is 600mm-800mm, and the distance between two adjacent guide walls 13 is 3m-5m. This arrangement is used to guide the waste liquid to flow smoothly in the collection tank 12, forming an S-shaped flow path, so as to extend the flow path of the waste liquid in the collection tank 12, evenly distribute the waste liquid flow, and better converge it to the sump 14, while better supporting the top plate 11 above, further enhancing the stability of the overall structure of the de-icing platform body 1.

[0047] As an optional implementation, Figure 3 , Figure 5 As shown, the sump 14 is connected to the flight area drainage ditch 5 through a drainage pipeline 6, and a valve is provided on the drainage pipeline 6.

[0048] Furthermore, an electric valve 7 and a check valve 8 are provided on the drainage pipeline 6. The electric valve 7 can be remotely controlled to open and close, so that rainwater in the collection pool 12 is discharged to the flight area drainage ditch 5 through the drainage pipeline 6 during the non-deicing season.

[0049] The function of the check valve 8 is to prevent rainwater from flowing back into the sump 14 or the collection tank 12 .

[0050] In the prior art, due to the design of the drainage ditch, deicing waste liquid and rainwater share the same drainage ditch, resulting in the confluence of rainwater and sewage, making cleaning difficult and easily polluting the environment. The present invention provides an independent drainage system to achieve rainwater and sewage diversion. For example, in the deicing season, the electric valve 7 and the check valve 8 of the drainage pipeline 6 connected to the flight area drainage ditch 5 are always in a closed state, and the waste liquid is stored in the collection pool 12 and pumped away by the deicing waste liquid collection vehicle through the suction well 16 to achieve rainwater and sewage diversion. In the non-deicing season, the deicing pad body 1 can be used to directly discharge rainwater. The electric valve 7 and the check valve 8 are opened, and the rainwater enters the flight area drainage ditch 5 through the drainage pipeline 6. The rainwater remaining in the sump 14 can be discharged by a rainwater pump.

[0051] As an optional implementation, an anti-corrosion layer is provided on the top plate 11; the inner wall and bottom plate of the collection tank 12 and the guide wall 13 are all provided with a waterproof and anti-corrosion layer.

[0052] Furthermore, the top plate 11 is sprayed with silane or other anti-corrosion materials in the prior art to form an anti-corrosion layer to improve durability.

[0053] The inner wall and bottom plate of the collection tank 12 and the guide wall 13 are all treated with waterproofing and corrosion resistance.

[0054] As an optional implementation, Figure 1 As shown, a plurality of inspection wells 15 are provided at the corners of the top plate 11 , and a water suction well 16 is provided at the corresponding sump 14 .

[0055] The size design of the inspection well 15 needs to meet the needs of normal entry and exit of operators.

[0056] The size design of the water suction well 16 needs to meet the requirements of normal operation of the de-icing waste liquid collection vehicle and facilitate the collection and discharge of the waste liquid.

[0057] As an optional implementation, Figure 1 As shown, an expansion joint 3 is provided between the deicing platform body 1 and the road panel 2 .

[0058] Furthermore, an expansion joint 3 is provided between the top plate 11 and the road surface plate 2 to adapt to the thermal expansion and contraction of the two caused by external environmental factors and extend the service life.
