Description

A kind of rescue flight umbrella

Technical field

The utility model relates to Aircrafts, more specifically to a kind of rescue flight umbrella.

Background technique

Nowadays, the place that cannot be reached for water route, land route, mostly uses aircraft to enter, and implements searching rescue, goods and materials fortune It send, the work such as airborne control operation, but there are four kinds of modes for existing flight system, such as one provide lift, but its volume for balloon type Greatly, action speed is slow, and manipulation ability is poor；Two provide lift for propeller and wing cooperation, but its resource is in short supply；Three mention for jet For onward impulse, wing is cooperated to provide lift；Four provide lift to depend merely on propeller；Three kinds of aircraft are by consuming a large amount of energy afterwards Amount is to obtain lift, and the power advanced in the sky is comparatively small, and energy utilization rate is low.

Utility model content

Problem to be solved in the utility model is, provides a kind of rescue flight umbrella, structure is simple, and low energy consumption.

In order to solve the above-mentioned technical problem, the utility model provides a kind of rescue flight umbrella comprising umbrella body, load cabin The umbrella body is arranged in inner concavity in body, helical fan, control cabinet, wind-guiding balance element and wind-guiding bottom case, the load cabin Middle part；The helical fan is annularly arranged in the periphery of the load cabin and is located at the lower section of the umbrella body；The wind-guiding Balance element ring is located at the periphery of the helical fan, and its upside cooperatively forms air duct with the umbrella body；The control cabinet setting In the lower section of the load cabin, it is equipped with motor in the control cabinet, the motor connect with the helical fan and can drive The helical fan is moved to dry downward；The bottom of the control cabinet is arranged in the wind-guiding bottom case, and the wind-guiding bottom case is cut Face is in " W " type structure, the periphery shape of the wind-guiding bottom case, helical fan and wind-guiding balance element in the control cabinet and load cabin At eddy flow cavity；The suction side of the helical fan is connected to the air duct, the positive pressure side of the helical fan and the eddy flow Cavity connection, the high-speed flow that the helical fan generates blow to downwards in the eddy flow cavity, and pass through the wind-guiding bottom case Change airflow direction, air-flow is made to blow to the inlet side in the air duct, is then reentered under the traction of the helical fan again In the eddy flow cavity, and the high speed rotation air-flow to move in circles is formed, while the inside of high speed rotation air-flow forms low pressure gas Group generates draught head with ambient atmosphere, and then provides lift for Aircraft.

A kind of rescue flight umbrella for implementing the utility model has the following beneficial effects: compared with prior art

The utility model using the low pressure air mass inside high speed rotation air-flow, make the atmospheric density inside Aircraft be lower than with The atmospheric density of ambient atmosphere generates buoyancy flight to reach, and the air-flow under flow at high speed will not escape, only few The windage of amount, kinetic energy rejection is few, and energy loss is few, obtains biggish flying power with lesser output, furthermore this is practical Novel structure is simpler compared with existing aircraft.

Detailed description of the invention

In order to illustrate more clearly of the technical solution of the utility model embodiment, the attached drawing of embodiment will be made below simple Ground introduction.

Fig. 1 is a kind of structural schematic diagram of rescue flight umbrella provided by the utility model.

Specific embodiment

The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without creative efforts Every other embodiment obtained, fall within the protection scope of the utility model.

As shown in Figure 1, the preferred embodiment of the utility model, a kind of rescue flight umbrella comprising umbrella body 1, load cabin 2, helical fan 3, control cabinet 4, wind-guiding balance element 5 and wind-guiding bottom case 6, the load cabin 2 are arranged in inner concavity in the umbrella The middle part of body 1；The helical fan 3 is annularly arranged in the periphery of the load cabin 2 and is located at the lower section of the umbrella body 1； 5 ring of wind-guiding balance element is located at the periphery of the helical fan 3, and its upside cooperatively forms air duct 8 with the umbrella body 1；Institute The lower section that the load cabin 2 is arranged in control cabinet 4 is stated, motor 7, the motor 7 and the spiral are equipped in the control cabinet 4 Fan 3 connects and the helical fan 3 can be driven to dry downward；The bottom of the control cabinet 4 is arranged in the wind-guiding bottom case 6 The section in portion, the wind-guiding bottom case 6 is in " W " type structure, and the wind-guiding bottom case 6, helical fan 3 and wind-guiding balance element 5 are described The periphery of control cabinet 4 and load cabin 2 forms eddy flow cavity 9；The suction side of the helical fan 3 is connected to the air duct 8, institute The positive pressure side for stating helical fan 3 is connected to the eddy flow cavity 9, and the high-speed flow that the helical fan 3 generates blows to downwards institute It states in eddy flow cavity 9, and airflow direction is changed by the wind-guiding bottom case 6, air-flow is made to blow to the inlet side in the air duct 8, with It is reentered under the traction of the helical fan 3 in the eddy flow cavity 9 again afterwards, and forms the high speed rotation gas to move in circles Stream, while the inside of high speed rotation air-flow forms low pressure air mass, generates draught head with ambient atmosphere, and then provide liter for Aircraft Power.

The utility model makes the atmospheric density inside Aircraft using the low pressure air mass inside high speed rotation air-flow as a result, Buoyancy flight is generated to reach lower than the atmospheric density with ambient atmosphere, and the air-flow under flow at high speed will not escape, Only a small amount of windage, kinetic energy rejection is few, and energy loss is few, obtains biggish flying power with lesser output, furthermore The structure of the utility model is simpler compared with existing aircraft.

Above disclosed is only the preferred embodiment of the utility model, certainly cannot be practical new to limit this with this The interest field of type, therefore equivalent variations made according to the patent scope of the utility model still belong to the utility model and are covered Range.
