On the basis of the above embodiments, the present embodiment further includes:

• • an attitude monitoring system, being provided on the folding runway 2 to monitor status data of the folding runway 2 itself and hydrological information of a location around the folding runway 2; and
  • an attitude control system, being electrically connected with the recovery apparatus 3, the contractile apparatus 4, the inflation and deflation apparatus 5 and the anchoring apparatus 6, respectively, to control the recovery apparatus 3, the contractile apparatus 4, the inflation and deflation apparatus 5 and the anchoring apparatus 6 to complete a corresponding action according to a corresponding control command.

The attitude control system may realize automation of the water surface foldable emergency-built runway, so that the recovery apparatus 3, the contractile apparatus 4, the inflation and deflation apparatus 5 and the anchoring apparatus 6 may act autonomously according to the control command sent by the attitude control system.

As shown in FIG. 2 and FIG. 3, the folding runway 2 specifically includes an external anti-skid drainage layer 21 and an internal reinforcement layer 22, the external anti-skid drainage layer 21 and the internal reinforcement layer 22 are bonded by an adhesive manner, and the external anti-skid drainage layer 21 and the internal reinforcement layer 22 further form a confined space and an unfolded shape of the folding runway 2 after being inflated is defined by wire drawing 23 (that is, a confined airbag structure is enclosed by the internal reinforcement layer 22, the external anti-skid drainage layer 21 is bonded to an external surface of the internal reinforcement layer 22, and then connected up and down in series between upper and lower opposite internal reinforcement layers 22 in the confined space formed by the internal reinforcement layer 22 through the dense wire drawing 23, so that the external anti-skid drainage layer 21 and the internal reinforcement layer 22 form an integrated structure like a wire drawing cloth, thereby limiting a final shape of the airbag structure after being inflated, and the wire drawing 23 is in a relaxed state without being inflated, and the internal reinforcement layer 22 will stretch outward according to the established shape under an action of the wire drawing 23 during inflating). The external anti-skid drainage layer 21 may be made of an EVA anti-skid pad, of course, it does not rule out the use of other materials that can achieve a function of drainage and anti-skid. The internal reinforcement layer 22 is made of an ultra-high molecular weight polyethylene fiber reinforced composite membrane material, of course, it does not rule out the use of other materials that can meet the strength required by the folding runway 2. Through the above settings, after the confined space enclosed by the external anti-skid drainage layer 21 and the internal reinforcement layer 22 is inflated, the external anti-skid drainage layer 21 and the internal reinforcement layer 22 expand outward according to the established overall shape under a tension condition of the wire drawing 23, unfold into a runway shape, and float on the water surface. The fully unfolded folding runway 2 has a flat surface, uniform stress distribution; an earth pressure can withstand 3 Mpa, which can meet the takeoff and landing of a light aircraft (such as a small fixed wing aircraft, a helicopter or a unmanned aerial vehicle); it has good air tightness, and one use may ensure a normal use for more than half a year; and it has high tensile strength, high tear strength, more than 10000 times of flex resistance, durability, and has advantages of simple fabrication and low fabrication cost.

In order to stabilize the structure, the first telescopic component 31 may be provided in a plurality. When providing a plurality of first telescopic components 31, the plurality of first telescopic components 31 act synchronously to enhance action consistency and stability thereof. In addition, the first telescopic component 31 can complete a telescopic action according to a control command sent by the attitude control system. When it is necessary to apply the folding runway 2, the attitude control system sends the control command to control the first telescopic component 31 to be launched gently to push the folding runway 2 out of the storage box 1. When it is necessary to recover the folding runway 2, the attitude control system sends the control command to control the first telescopic component 31 to be recovered slowly to bring the folding runway 2 from the outside of the storage box 1 into the storage box 1, so as to improve automation performance thereof.

As shown in FIG. 4, the contractile apparatus 4 specifically includes a plurality of second telescopic components 41 and a plurality of third telescopic components 42, the plurality of second telescopic components 41 are provided on the folding runway 2 at intervals between each other, and the plurality of third telescopic components 42 are provided between the two adjacent second expansion components 41 at intervals between each other. The second telescopic component 41 and the third telescopic component 42 may adopt the existing mechanical telescopic structure or adopt the structure such as the multi-stage air/hydraulic cylinder. Two second telescopic components 41 and three third telescopic components 42 are shown in FIG. 4, of course, the number of second telescopic components 41 and third telescopic components 42 may also be changed according to a size of the folding runway 2. Through the above settings, the second telescopic component 41 may be used to assist the folding runway to complete the folding along its length, and the third telescopic component 42 may be used to assist the folding runway 2 to complete the folding along its width. In addition, the second telescopic component 41 and the third telescopic component 42 can complete the above action according to the control command sent by the attitude control system to improve the automation performance thereof.

As a further improvement, the active end of the first telescopic component 31 is connected with the folding runway 2 through the second telescopic component 41 close to the storage box 1. Through the above setting, the first telescopic component 31, the second telescopic component 41 and the third telescopic component 42 form a whole. When unfolding the folding runway 2, after the first telescopic component 31 is used to complete an unfolding action to push the folding runway 2 out of the storage box 1, the second telescopic component 41 and the third telescopic component 42 are used to perform the unfolding action to unfold the folding runway 2. When folding the folding runway 2, after the second telescopic component 41 and the third telescopic component 42 are used to perform a folding action to fold the folding runway 2, the first telescopic component 31 is used to complete the folding action to recover the folding runway 2 into the storage box 1.

As shown in FIG. 2, the inflation and deflation apparatus specifically includes an inflation apparatus 51, an evacuation apparatus 52, an inflation valve 53 and an exhaust valve 54, the inflation apparatus 51 is communicated with the interior of the folding runway 2 through an inflation pipeline 55, the inflation valve 53 is mounted on the inflation pipeline 55, the evacuation apparatus 52 is connected with one end of the exhaust valve 54 through an exhaust pipeline 56, and the other end of the exhaust valve 54 is connected with the inflation pipeline 55. It can be understood that inflation apparatus 51 may use an inflation device such as an air inflator, the evacuation apparatus 52 may use an evacuation device such as a vacuum air pump, and the inflation valve 53 and the exhaust valve 54 may use a valve such as a solenoid valve. In order to ensure that the folding runway 2 may be pushed out and taken back from the storage box 1, the inflation pipeline 55 connected with the folding runway 2 is designed as a flexible pipeline with high strength. In addition, the inflation apparatus 51 and the evacuation apparatus 52 can start and stop automatically according to the control command sent by the attitude control system, and the inflation valve 53 and the exhaust valve 54 can start and close automatically according to the control command sent by the attitude control system to improve the automation performance thereof.

The first telescopic component 31, the second telescopic component 41 and the third telescopic assembly 42 may also be provided as multistage air cylinders, and the first telescopic component 31, the second telescopic component 41 and the third telescopic component 42 share the inflation apparatus 51, the evacuation apparatus 52, the inflation valve 53 and the exhaust valve 54 with the folding runway 2. During the unfolding operation, the first telescopic component 31, the second telescopic component 41 and the third telescopic component 42 are synchronously stretched while inflating the folding runway 2, thereby shortening an unfolding time of the folding runway 2. During the folding operation, the first telescopic component 31, the second telescopic component 41 and the third telescopic component 42 are synchronously retracted while deflating the folding runway 2, thereby shortening a folding time of the folding runway 2. Therefore, the construction time of folding runway 2 is shortened to win valuable time for a unit using the runway.

As shown in FIG. 2 and FIG. 3, in order to ensure that the folding runway 2 can be more stably fixed on the water surface after being unfolded, the anchoring apparatus 6 is provided in a plurality. The anchoring apparatus 6 specifically includes an anchor chain recovery and launch apparatus 61, an anchor chain 62 and an anchor 63, one end of the anchor chain 62 is connected with the anchor chain recovery and launch apparatus 61, and the other end of the anchor chain 62 is fixedly connected with the anchor 63; when the folding runway 2 is in the folding state, the anchor chain 62 is in a recovery state, and when the folding runway 2 is in the unfolding state, the anchor chain 62 is in a launch state. In practical applications, the anchor chain recovery and launch apparatus 61 is generally fixed and mounted on a bottom face of the folding runway 2 (that is, a side of the folding runway 2 contacting the water surface when it is unfolded). The anchor chain recovery and launch apparatus 61 may adopt a coiler to fix the anchor chain 62 by means of winding. In order to facilitate to disconnect the anchor chain 62 when recovering the folding runway 2, an end of the anchor chain 62 that is not fixed with the anchor 63 may be hung on a bulge provided on a spool of the anchor chain recovery and launch apparatus 61. When fixing the folding runway 2, the anchor chain 62 will reserve a section to be wound on the spool of the anchor chain recovery and launch apparatus 61. When recovering the folding runway 2, the spool of the anchor chain recovery and launch apparatus 61 continues to rotate, and the anchor chain 62 will fall off the bulge of the spool due to its own gravity, so that the folding runway 2 will get rid of bondage of the anchor chain 62. In the next use, the new anchor chain 62 and anchor 63 are replaced so as to be used for the next time.

On the basis of the above embodiments, the attitude monitoring system in the present embodiment specifically includes a sensor, the sensor is provided on the folding runway 2, and the sensor is electrically connected with the attitude control system. The sensor includes a shaft angle encoder, a vibration sensor, a pressure sensor, a liquid level sensor, a wind direction sensor and other sensors. Additional sensors with different functions may be added according to the required functions. The attitude control system includes a data processor, which may perform an analog-to-digital conversion and a corresponding settlement output on the data collected by various sensors, and then send the control command to the recovery apparatus 3, the contractile apparatus 4, the inflation and deflation apparatus 5 and the anchoring apparatus 6. The data processor may adopt a DSP (Digital Signal Processor) digital signal processor, a FPGA (Field Programmable Gate Array) field programmable gate array, a MCU (MicrocontrollerUnit) system board, a SoC (system on a chip) system board, or a PLC (Programmable Logic Controller) minimum system including I/O.

A specific use process of the present disclosure is as follows. When it is necessary to unfold, the attitude control system sends a command to control the first telescopic component 31 to push the folding runway 2 out of the storage box 1, turn on the inflation valve 53, and turn off the exhaust valve 54. Then a high-pressure gas is injected from the inflation apparatus 51 into the confined space enclosed by the external anti-skid drainage layer 21 and the internal reinforcement layer 22 through the inflation pipeline 55. At the same time, the plurality of second telescopic components 41 and the plurality of third telescopic components 42 are stretched outward to expand the light flexible folding runway 2 outward according to the established overall shape, at the same time it is tensioned through the high-strength wire drawing 23, and after sufficient gas is inflated and a certain pressure is reached, the folding runway 2 is unfolded into a flat shape to float on the water surface. The anchoring apparatus 6 launches a plurality of groups of anchors 63 into the water bottom through the anchor chain recovery and launch apparatus 61 and fix them to constitute the runway, which provides a takeoff and landing runway for the small fixed wing aircraft or helicopter. At the same time, the attitude monitoring system monitors parameters such as hydrological conditions and an internal pressure of folding runway 2 through various sensors.

When it is necessary to recover, the attitude control system sends a command to start the anchoring apparatus 6, disconnect the anchor chain 62 connecting the plurality of groups of anchors 63 through the anchor chain recovery and launch apparatus 61, then turn on the exhaust valve 54 and the evacuation apparatus 52, and turn off the inflation valve 53. The high-pressure gas is deflated from the confined space enclosed by the external anti-skid drainage surface 21 and the internal reinforcement layer 22, while the plurality of second telescopic components 41 and the plurality of third telescopic components 42 contract outward, and after the air in the folding runway 2 is completely deflated, the first telescopic component 31 provided in the storage box 1 is recovered, and the folding runway 2 is recovered into the storage box 1 for storage.

Before the next use, it is only necessary to connect the new anchor 63 and anchor chain 62 with the anchor chain recovery and launch apparatus 61, that is, it can be reused.

The above are merely the embodiments of the present disclosure and are not intended to limit the present disclosure. For those skilled in the art, the present disclosure may have various changes and variations. Any amendments, equivalent alternatives, improvements and the like made within the spirit and principle of the present disclosure shall be included in the scope of claims of the present disclosure.
