Referring to fig. 1, there is shown a diagram of one example of the construction of a high mobility rescue hovercraft as given in this example. As can be seen, the high maneuver rescue hovercraft 100 structurally comprises a hull 110, a skirt 120 disposed on the hull, a control system 130, a power system 140, a propulsion fan 150, an uplift fan 160, a pod 170, and a drive device 180.

The hull 110 forms an overall rescue hovercraft structure providing a region for the location of other components of the rescue hovercraft. The specific structure can be determined according to actual requirements.

By way of example, the aft portion of the hull 110 in this example serves as a powerplant mounting area; the middle part is provided with a corresponding cabin 111 to provide a cockpit and a passenger cabin; the front of the hull 110 serves as a control system installation area for installing a corresponding control system 130.

Further, the hull 110 in this example is provided with a corresponding transparent windscreen 112 in front of the hold 111. Corresponding illumination lamps 113 are provided at both sides of the front of the hull 110 as necessary.

Further, the hull 110 in this example is provided with a plurality of rescue tools in the cabin 111 to improve the rescue function of the hovercraft to face various emergencies.

In the embodiment, the skirt 120 is detachably arranged with the hull 110, so that the maintenance and repair in the using process are convenient, and the using cost is reduced. The specific structure of the detachable structure used herein may be determined according to actual requirements, and is not described herein.

The control system 130 in this embodiment is located on the hull 110, preferably forward of the hull 110, and within the cockpit, thereby facilitating pilot control.

The control system 130 is used for controlling the connection power system 140, the propulsion fan 150, the lift fan 160, and the like, and controlling the operation states of these components.

The specific configuration of the control system 130 can be determined according to actual requirements, and will not be described herein. Such as, but not limited to, the operational controller of an existing hovercraft.

In order to improve the communication level and performance of the hovercraft in the application process, the control system is further provided with auxiliary equipment such as a 5G communication module, a GPS positioning device and a Beidou positioning device.

The power system 140 in this embodiment is provided in the hull 110 for providing the power required for the operation of the propulsion fan 150 and the lift fan 160.

The power system 140 is preferably located in the aft cabin of the hull 110, controlled by the control system 130, and is connected to the propulsion fan 150 and the lift fan 160 through a transmission system. The configuration of the power system 140, which is not described in detail herein, may be determined according to actual requirements, such as the configuration of the power system used in the conventional hovercraft, or any other feasible power scheme, such as an electric or fuel-powered power device.

The lift fan 160 in this embodiment is disposed in the hull 110 and is in communication with the lift air duct in the hull, and can generate high-speed airflow for lifting the hull under the driving of the power system 140.

The lift fan 160 is preferably disposed at two sides of the rear of the hull 110 in the cabin, and has corresponding vents 114 formed therein. This arrangement does not allow high-speed airflow for elevating the hull with high strength to be generated, and also effectively suppresses noise generated when the elevating fan 160 operates.

The structure of the lift fan 160 will not be described in detail herein, and may be determined according to actual requirements, such as the lift fan scheme adopted by the hovercraft in the prior art, or any other feasible scheme.

The propulsion fan 150 in the scheme is arranged in the middle area of the rear part of the ship body 110 and is connected with the power system 140 in the cabin, and can generate high-speed airflow for pushing the ship body to advance by the height towards the rear part of the ship body under the driving of the power system 140.

The construction of the propulsion fan 150 will not be described in detail herein, and may be determined according to actual requirements, such as the construction of the propulsion fan 150 adopted by the hovercraft, or any other feasible construction.

By way of example, the propulsion fan 150 in this example is formed by a corresponding fan 151 and an inverted trumpet-shaped flow focusing shroud 152, wherein the fan 151 is rotatably disposed at a large mouth section of the flow focusing shroud 152.

On the basis, the scheme further arranges the wind direction adjusting devices on two sides of the propulsion fan 150 to adjust the direction of the high-speed airflow generated by the propulsion fan 150, so as to adjust the moving direction of the hovercraft and enable the hovercraft to move backwards directly without affecting the safety and comfort of passengers.

As shown, the wind direction adjusting device in this example is formed by the corresponding air guide sleeve 170 and the driving device 180. The air guide covers 170 are adjustably distributed on two sides of the propulsion fan 150, and the driving device 180 is in driving connection with the air guide covers 170 distributed on two sides of the propulsion fan and can respectively drive the air guide covers to swing relative to the propulsion fan 150 so as to form air flow channels in corresponding directions between the two sides and the propulsion fan respectively and form reverse air channels facing the front part of the ship body, thereby realizing the adjustment of the moving direction of the hovercraft and the direct reverse movement of the hovercraft.

Specifically, the air guide sleeve 170 herein adopts an inward concave arc-shaped groove air guide structure, that is, the side surface of the air guide sleeve 170 facing the propulsion fan is a dihedral angle structure with an angle smaller than 180 °, and the side surface is integrally concave to form the arc-shaped guide groove 171.

The fairings 170 thus constructed are symmetrically disposed at both sides of the propeller fan 150 to be swingable, and the fairings 170 at each side may swing with respect to the propeller fan 150 with the middle portion as a pivot point. Thus, each pod 170 oscillates at one end toward the pusher fan 150 and synchronously oscillates at the other end away from the pusher fan 150.

Moreover, an end 172 of each air guide sleeve 170 opposite to the air outlet end of the propulsion fan 150 (i.e., the air outlet of the flow collecting sleeve 152 in the propulsion fan 150) can just cover the air outlet end and the air outlet of the propulsion fan 150 when swinging towards the propulsion fan 150; when the end 172 of the two fairings 170 opposite to the air outlet end of the propulsion fan 150 (i.e. the air outlet of the flow-focusing cover 152 in the propulsion fan 150) swings facing the propulsion fan 150, it can just cover the whole area of the air outlet end and the air outlet of the propulsion fan 150. At this time, the air outlet of the propulsion fan 150 is respectively communicated with the arc grooves in the fairings at the two sides, the arc grooves 171 in the fairings at the two sides are respectively matched with the outer side wall 153 of the propulsion fan 150 (i.e. the outer side wall of the flow-gathering cover 152 in the propulsion fan 150), the two sides of the propulsion fan 150 are respectively provided with an oblique air duct facing the front side part of the ship body, and the oblique air duct at each side extends from the middle part of the rear part of the ship body to the front side part of the ship body at the same side.

Therefore, the inclined air ducts formed at the two sides of the propulsion fan 150 form corresponding backward air ducts to guide the high-speed airflow ejected from the air outlet end of the propulsion fan 150, so that the high-speed airflow ejected directly backwards from the air outlet end of the propulsion fan 150 is converted into the high-speed airflow ejected from the two sides of the propulsion fan 150 to the two sides of the ship body obliquely forwards, and the inclined thrust synchronously generated at the two sides is matched to form backward power, thereby realizing the backward function of the hovercraft.

The high-speed airflow for generating the back power is sprayed out from two sides of the propulsion fan 150 to the oblique front sides of two sides of the ship body, so that the airflow directions of the two sides just avoid the cabin part of the ship body, personnel in the cabin cannot be influenced, and the safety and the comfort of the passengers are ensured.

Moreover, the air guide cover 170 adopts a specific concave arc-shaped groove air guide structure and is symmetrically distributed on two sides of the propulsion fan 150, so that a good inhibiting effect can be formed on huge noise generated when the propulsion fan 150 works, the noise generated when the hovercraft runs can be greatly reduced, and the riding comfort level is improved.

The driving means 180 in this example is provided on the corresponding hull and drivingly connects the pod 170 to drive both ends of the pod 170 to swing with respect to the propulsion fan 150, respectively. The specific configuration and arrangement of the driving device 180 can be determined according to actual requirements, and will not be described herein.

By way of example, the drive means 180 may consist of respective hydraulic or pneumatic drive rods and be controlled by the control system 130.

As shown in fig. 2, in order to further improve the performance of the high mobility rescue hovercraft, in the present embodiment, a corresponding hard friction layer 115 is further disposed at the bottom of the hull 110, and the hard friction layer 115 covers the whole bottom of the hull 110, so as to improve the strength and reliability of the whole hovercraft, enable the hovercraft to enter various regions to perform rescue activities, and improve the range of activities.

The specific structure of the hard friction layer 115 may be determined according to actual requirements. By way of example, a high-strength carbon fiber plate may be used, which may be formed by splicing several carbon fiber plate units.

Further, the present example also provides corresponding stowable wheels 190 at the bottom of the hull 110, which enables the hovercraft to move on land in addition to on the water.
