Description

Technical Field

[0001] The invention relates to the technical field of rail transit, in particular to a low-altitude and track dual-purpose base based on a rail transit vehicle yard. Background Art

[0002] As helicopters, eVTOL (electric vertical take-off and landing), and fixed-wing aircraft gradually come into the public eye, low-altitude flights with general aviation airports as support bases have basically been realized. However, due to the lack of take-off and landing points in urban areas and other reasons, urban areas usually only have a small number of take-off and landing points deployed in large hospitals, large squares, and commercial complexes, and there are very few areas that can accommodate the parking of two or more low-altitude aircraft. At present, a large number of low-altitude aircraft are parked at general aviation airports, which are usually far away from urban areas and cannot quickly reach designated locations in urban areas, making it difficult to meet the urban area's needs for high-efficiency personnel and cargo transportation.

[0003] The invention patent with application publication number CN118597432A discloses a multifunctional general airport for use by low-altitude aircraft. The general airport can be directly built in the urban area without being built far away from the urban area. Although this solution solves the problem that aviation airports are usually far away from urban areas, it requires the construction of a general airport for use by low-altitude aircraft, and the general airport can only meet the use of low-altitude equipment and does not have other functional attributes. Summary of the invention

[0004] In view of the shortcomings of the prior art, the purpose of the present invention is to provide a low-altitude and rail dual-use base based on a rail transit vehicle yard. By utilizing the three-dimensional space of the rail transit vehicle yard, the support needs of low-altitude flight are met, the traditional two-dimensional space limitations are broken, the utilization rate of three-dimensional space is improved, and land resources are saved.

[0005] In order to achieve the above object, the present invention is implemented through the following technical solutions:

[0006] A low-altitude and rail dual-use base based on a rail transit vehicle yard includes a rail transit vehicle yard, a subway train enclosed base is arranged in the yard, a low-altitude base is formed on the top of the subway train enclosed base, a plurality of helipads are arranged at the low-altitude base, and the helipads are used to realize the parking and take-off of low-altitude aircraft.

[0007] As a further implementation method, the low-altitude base is divided into two types: parking base and parking and maintenance base according to the size and positioning of the closed base for subway trains.

[0008] As a further implementation method, the parking aprons on the parking base are all fixed parking aprons.

[0009] As a further implementation method, the apron on the parking and maintenance base is divided into a plurality of fixed aprons and at least one group of liftable aprons, and the liftable apron can be lowered to the inside of the closed base of the subway train.

[0010] As a further implementation method, the liftable helipad is arranged at one end of the closed base of the subway train away from the vehicle track. A maintenance plant is also arranged inside the closed base of the subway train, and the maintenance plant is arranged close to the liftable helipad.

[0011] As a further implementation method, at least one group of elevators is provided at the end of the closed base of the subway train, and the elevators can rise to the low-altitude base.

[0012] As a further implementation method, the liftable helipad and the maintenance plant are arranged along the width direction of the closed base of the subway train, and the low-altitude aircraft on the liftable helipad can be moved to the maintenance plant by a transfer device.

[0013] As a further implementation method, a municipal road is configured outside the closed base of the subway train, and the municipal road extends to the inside of the closed base of the subway train.

[0014] As a further implementation method, the municipal roads are located on both sides of the rail transit vehicle yard, and the municipal roads are parallel to the vehicle tracks.

[0015] As a further implementation method, corresponding infrastructure is constructed on the low-altitude base.

[0016] The beneficial effects of the present invention are as follows:

[0017] 1. The rail transit vehicle yard of the present invention is provided with a closed base for subway trains in the yard, and a low-altitude base is formed on the top of the closed base for subway trains; on the basis of ensuring the normal operation of the original rail transit vehicle base, the three-dimensional space of the rail transit vehicle yard is utilized to meet the guarantee demand for low-altitude flight, break through the traditional two-dimensional space limitation, improve the utilization rate of three-dimensional space, and save land resources.

[0018] 2. Since rail transit vehicle yards are basically distributed around urban areas, they can reduce the spatial distance between low-altitude aircraft from traditional general aviation airports to urban areas, save flight time, and improve the utilization efficiency of low-altitude aircraft in urban areas.

[0019] 3. The outer side of the rail transit vehicle yard of the present invention is also configured with a municipal road, which realizes the seamless connection of low-altitude flight, rail transit and municipal roads.

[0026] It should be noted that the following detailed descriptions are illustrative and intended to provide further explanation of the present invention. Unless otherwise specified, all technical and scientific terms used in the present invention have the same meanings as those commonly understood by those skilled in the art to which the present invention belongs.

[0027] Embodiment 1

[0028] In a typical embodiment of the present invention, reference is made to Figure 1-Figure 3 As shown, a low-altitude and rail dual-use base based on a rail transit vehicle yard includes a rail transit vehicle yard, in which a subway train enclosed base 03 is arranged, and a low-altitude base is formed on the top 04 of the subway train enclosed base. A number of aprons are arranged at the low-altitude base, and the aprons are used to realize the parking and take-off of low-altitude aircraft.

[0029] It is understandable that rail transit vehicle depots mainly provide necessary logistical services for the daily operation of subway vehicles, undertake functions such as rail transit vehicle parking, daily maintenance and overhaul, train rescue, equipment maintenance, system maintenance, and material supply. They are usually located on the edge of the city or in areas with fewer people in the urban area, occupy a large area and have fewer high-rise buildings around them, which can provide good airspace conditions and good clearance conditions for low-altitude aircraft. Therefore, there is idle space in the three-dimensional space of the rail transit vehicle depot, and its interior can provide daily maintenance and repair space for low-altitude aircraft through renovation and expansion. Its top can provide a large number of parking spaces for low-altitude aircraft, and it has the ability to create a "low-altitude + rail" dual-use base based on the rail transit vehicle depot, realizing economical and intensive land use.

[0030] The traditional rail transit vehicle yard is mainly composed of vehicle track 01, subway train 02, and subway train closed base 03, among which the top of the subway train closed base 04 is an important component of the subway train closed base 03, and its structure includes steel structure, concrete structure and other types according to different functional uses.

[0031] like Figure 1 As shown, a subway train closed base 03 and a vehicle track 01 are provided in the rail transit vehicle yard, wherein the subway train closed base 03 is located above the end of the vehicle track 01, and the subway train 02 travels to the subway train closed base 03 through the vehicle track 01, providing necessary logistical services for the daily operation of the subway vehicle.

[0032] like Figure 1 and Figure 2 As shown, the top of the subway train closed base 04 forms a low-altitude base, on which there are several aprons, which are used to park and take off low-altitude aircraft. The scale of the low-altitude base is smaller than that of the general aviation airport, but it is closer to the urban area and can reach the urban area in a shorter time; it can be divided into two parts according to the use area: the top of the closed site of the rail transit vehicle yard is mainly responsible for the parking of low-altitude aircraft, communication and navigation, air traffic control, meteorological information, etc.; the inside of the closed site of the rail transit vehicle yard is mainly responsible for daily maintenance and inspection of functions.

[0033] Specifically, the low-altitude base is divided into two types: a parking base and a parking and maintenance base according to the size and location of the subway train closed base 03. When the subway train closed base is small, only the parking base is set, that is, no maintenance workshop 09 is set inside the subway train closed base, and the parking aprons on the parking base are all fixed parking aprons 05.

[0034] like Figure 1 and Figure 2As shown, the top 04 of the closed base of the subway train in this embodiment is a parking and maintenance base, which can not only realize the take-off and parking of low-altitude aircraft, but also carry out maintenance on the low-altitude aircraft.

[0035] Low-altitude aircraft mainly include helicopters, eVTOL (electric vertical take-off and landing), medium and large UAVs, vertical take-off and landing fixed-wing UAVs, and other low-altitude aircraft that can take off and land vertically.

[0036] The parking apron on the parking and maintenance base is divided into several fixed parking aprons 05 and at least one group of liftable parking aprons 07, and the liftable parking apron 07 can be lowered to the inside of the closed base of the subway train. The parking apron is used to park low-altitude aircraft 06.

[0037] This embodiment is provided with nine groups of fixed aprons 05 and one group of liftable aprons 07. The ten groups of aprons are divided into two rows, with five groups in each row. Figure 1 In the view direction, the right end is the end of the vehicle track 01 and the subway train closed base 03. The subway train 02 can travel to the subway train closed base 03 via the vehicle track 01. The fixed apron 05 only ensures the take-off and landing of the aircraft, and the liftable apron 07 can ensure the take-off and landing of the low-altitude aircraft 06 and land the low-altitude aircraft 06 to the maintenance workshop 09.

[0038] The liftable helipad 07 of this implementation is located at one end of the subway train closed base 03 away from the vehicle track, and a maintenance workshop 09 is also provided inside the subway train closed base 03, and the maintenance workshop 09 is arranged near the liftable helipad 07. The maintenance workshop 09 is located at the end of the subway train closed base 03 and does not affect the normal operation and maintenance of rail transit vehicles.

[0039] like Figure 3 As shown, the liftable helipad and the maintenance plant are arranged along the width direction of the closed subway train base 03. After the low-altitude aircraft 06 on the liftable helipad 07 descends into the closed subway train base 03, it can be moved to the maintenance plant 09 for maintenance through the transfer device 14. The transfer device 14 is a prior art.

[0040] At the end of the subway train closed base 04, at least one group of elevators is provided, which is a vertical elevator 08, and is an important connecting passage between the closed area of ​​the rail transit vehicle yard and the low-altitude base, ensuring the safe and efficient passage of goods 12 and personnel 13. The vertical elevator 08 can be used to ascend from the inside of the subway train closed base to the low-altitude base.

[0041] This embodiment forms a "low-altitude + rail" dual-use base based on the rail transit vehicle yard, which can provide low-altitude aircraft parking, maintenance and efficient transfer services for personnel and goods on the basis of meeting the original rail vehicle functions.

[0042] Further, such as Figure 1 As shown, a municipal road 10 is arranged outside the closed base 03 of the subway train, which is convenient for the transportation of vehicles 11 and realizes the connection between the municipal road 10 and the yard. The municipal road 10 extends to the inside of the closed base of the subway train, and a corresponding parking lot can be arranged inside the base as a supplement to the "low-altitude + rail" transportation, realizing efficient connection with rail transit and low-altitude flight, covering areas that low-altitude flight and rail transit cannot cover, and improving the efficiency of transportation of personnel and goods.

[0043] Preferably, the municipal roads 10 are located on both sides of the rail transit vehicle yard, and the municipal roads 10 are parallel to the vehicle track 01 to ensure the clearance requirements of the low-altitude base. The low-altitude base is built with corresponding infrastructure, such as communication navigation, air traffic control, command and dispatch infrastructure, etc., at the top of the rail transit vehicle yard, and the daily maintenance and repair workshop is located in the rail transit vehicle yard.

[0044] In this embodiment, the "low-altitude + rail" comprehensive support base based on the rail transit vehicle depot needs to be equipped with a series of low-altitude flight service devices such as communication, navigation, monitoring, and meteorology on the basis of having all the functions of the rail transit vehicle depot to ensure the low-altitude flight safety of the base. According to the size and location of the vehicle base, it is divided into two types: parking base and parking and maintenance base.

[0045] The fixed helipad 05 and the liftable helipad 07 are confirmed according to actual needs. When the low-altitude aircraft 06 does not need maintenance, it is mainly parked on the fixed helipad 05. When the liftable helipad 07 is not in use, it can be temporarily used as the fixed helipad 05. When the low-altitude aircraft 06 needs maintenance, it can be transported to the maintenance workshop 10 through the liftable helipad 07 via the transfer device 14. After the maintenance is completed, it is transported to the liftable helipad 07 via the transfer device 14, thereby completing a maintenance.

[0046] like Figure 1-Figure 3 As shown in the figure, a "low-altitude + rail" passenger flow and logistics hub base based on the rail transit vehicle yard is given. The distribution methods include "low-altitude + rail", "low-altitude + municipal roads" and "rail + municipal roads". The three complement each other to achieve efficient distribution of personnel and goods.

[0047] “Low altitude + track” mainly connects the closed base 03 of the subway train with the top 04 of the closed base of the subway train through the vertical elevator 08. Multiple vertical elevators 08 can be set up according to needs to realize the convenient transfer of personnel 12 or goods 13.

[0048] "Low altitude + road" and "railway + road" are supplements to the "low altitude + railway" distribution method, connecting the municipal road 10 with the rail transit vehicle yard, mainly taking over areas that are difficult to cover in one stop by subway trains 02 and low-altitude aircraft 06, and transporting people 12 or goods 13 to designated locations through vehicles 11.

[0049] The rail transit vehicle depot of this embodiment is, firstly, a comprehensive service base, providing parking, maintenance and other services for rail transit vehicles and low-altitude aircraft; secondly, a hub base for the transportation of personnel and goods, constructing a transfer site with rail transit and low-altitude flight as the main body and road transportation as the auxiliary, to achieve efficient transportation of personnel and goods.

[0050] This embodiment overcomes the problems of few take-off and landing points for low-altitude aircraft in existing urban areas, and the distance of general aviation airports from urban areas, making it difficult to meet the growing demand for low-altitude transportation. In combination with the actual needs of low-altitude flight, the three-dimensional space of the rail transit vehicle yard is fully utilized, and a "low-altitude + rail" dual-use base based on the rail transit vehicle yard is proposed, which effectively connects the three modes of transportation of rail transit, road transportation, and low-altitude flight, realizes the efficient use of the three-dimensional space, and does not require the construction of additional low-altitude airports. On the premise of saving costs, the three-dimensional space of the rail transit vehicle yard is reasonably utilized, thereby realizing economical and intensive land use.

[0051] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
