Description

A holdover device TECHNICAL FIELD

[0001] The present application relates to the field of aerial vehicles, and in particular to a holdover device BACKGROUND

[0002] Many aspects of life need to leave the device in the air to work from the air, achieve various purposes, for example, high-altitude video monitoring, high-altitude lighting for rescue and disaster relief, high-altitude network relay and entertainment, etc. People use some aircraft-like devices to achieve these functions. Aircraft flying consumes fuel and electrical energy and other energy sources. The weight of the engine and fuel or the motor and battery accounts for more than 90% of the weight of the entire aircraft. That is, the aircraft must overcome and exceed this part of the gravity to be able to fly in the air. In order to enable the aircraft to fly for a long time while saving energy, people have invented tethered aircraft. Through ground devices, energy is continuously supplied to the aircraft to achieve long-term flight to complete the set task. The most commonly used in the prior art is to supply electrical energy from the ground to the aircraft driven by the motor and propeller through the cable. Although this type of tethered aircraft moves the power supply to the ground, it has the disadvantage that the aircraft needs a large current to work, and the cable increases the weight. If high-voltage current is used, there is a risk of high-voltage breakdown, and the aircraft still needs to overcome and exceed the motor gravity to fly in the air. For example, application publication number CN107140229A provides a tethered unmanned aerial vehicle energy supply system. The energy transmitted from the ground to the aircraft is fuel gas transported through the pipeline. The fuel cell, battery or super capacitor, and power controller are installed on the unmanned aerial vehicle. The disadvantage of this technical solution is that the aircraft still needs to overcome and exceed the gravity of the fuel cell to fly in the air. Application publication number CN110963067A provides a fuel delivery method for a tethered unmanned aerial vehicle system and a tethered unmanned aerial vehicle system. The sensor controls the valve at the unmanned aerial vehicle end to be in an open state or a closed state. The tethered cable supplies fuel from the ground fuel equipment to the engine of the unmanned aerial vehicle in the tethered unmanned aerial vehicle system. The application publication number CN109808884A provides a tethered unmanned aerial vehicle. The ground mechanism has a power supply and / or a working medium supply. The ground mechanism is used to supply power to the power component and / or supply working medium to the working component through the connecting cable. These aircrafts all deliver fuel-like energy to the aircraft, and the energy conversion device on the aircraft converts the energy into kinetic energy, which acts on the air to fly. For example, the fuel cell converts fuel gas into electrical energy, which is generated by the motor and propeller to produce rotation and lift. Or the electrical energy is stored in the battery for standby. The disadvantage of this type of aircraft is that it needs to set up energy conversion devices such as fuel cells and internal combustion engines on the aircraft. These devices increase the dead weight of the aircraft, which seriously affects the efficiency of the aircraft.There is also a kind of entertainment water flying vehicle, using water pumping device to pressurize water, through the water pipe to the top of the aircraft, through the human body control or controller for aircraft control to spray water flow downward, using the reaction force of water to generate lift, for example, the application publication number: CN206155791U discloses an intelligent water flying vehicle, its main content is to use the high pressure water pump carried by the motorboat to follow the movement, and the water is transported to the water flying vehicle through the pipeline, the water flying vehicle is provided with downward nozzle, and the water flying vehicle is flown by using the reaction force of downward water spray; The disadvantage of this kind of aircraft is that because a large amount of water is needed as power, it must be used in lakes, rivers and other water surfaces, and it cannot be used in arid areas. Even if a large water tank is carried by a large vehicle, the water sprayed in all directions during the working process is also a difficult problem to solve, and it cannot be used in many environments such as power maintenance, rescue lighting, network support and the like. In addition, due to the large specific gravity of water, a few hundred horsepower of motorboat can only send a person to a maximum height of tens of meters, the height has reached the limit, and the pipeline for transporting water bears high pressure, therefore, although such a water flying vehicle has been invented for many years, it cannot undertake the working task and becomes a tool for entertainment on the water surface; The above-mentioned air holding device has low efficiency, small payload and short air holding time, and needs to be improved.

[0065] Figure 11 is a schematic diagram of another embodiment of the control device of the space holding device of the present application, wherein the space holding device is different from the embodiment of Figure 10 in that the control valves 33 are arranged in the jet ports 34, and the valve flaps 332 protrude downwardly from the jet ports 34. The working principle is described with reference to Figure 14, wherein the arrows outside the valve flaps 332 represent the rotation direction of the valve flaps 332 as viewed from the outside of the valve flaps 332, the dashed lines passing through the valve flaps 332 represent the rotation axes of the valve flaps 332 and the valve rotation shafts 331, the vertical dashed lines represent the vertical direction, the control valves 33 arranged in the jet ports 34 are uniformly distributed in the same circular horizontal plane, the rudders 333 are arranged on the outer wall of the jet ports 34 facing the center of the control device 3 or on the outer wall of the jet ports 34 away from the center of the control device 3. In Figure 11, the rudders 333 are arranged on the inner wall. The valve rotation shafts 331 are directed to the center of the circular plane formed by the control valves 33. The control method is as follows. Four control valves 33 are symmetrically arranged, and are uniformly distributed around the central cavity 30 of the control device 3. The rotation direction of the valve flaps 332 is determined as viewed from the outside of the valve flaps 332, including clockwise and counterclockwise directions. The initial position of the valve flaps 332 is the vertical direction. When all the valve flaps 332 are rotated in the clockwise direction, the valve flaps 332 are inclined, and the airflow emitted from the jet ports 34 is inclined to be emitted in the clockwise direction. The inclined airflow generates an inclined force, wherein one component force direction generates a reaction force acting on the control device 3 in the counterclockwise direction as viewed from the top of the control device 3, so that the control device 3 is forced to rotate in the counterclockwise direction. According to the same principle, when all the valve flaps 332 are rotated in the counterclockwise direction, the control device 3 is forced to rotate in the clockwise direction. When one of the two symmetric valve flaps 332 located on both sides of the central cavity 30 is rotated in the clockwise direction, and the other valve flap 332 is rotated in the counterclockwise direction, the airflow passing through the two valve flaps 332 is inclined to be emitted in one direction of the control device 3, so that the control device 3 is forced to move in the horizontal direction. When one of the two adjacent valve flaps 332 is rotated in the clockwise direction, and the other valve flap 332 is rotated in the counterclockwise direction, the airflow emitted from the jet ports 34 is reduced, and the component forces generated by the direction inclination cancel each other out, so that no rotation torque and horizontal torque are generated on the control device 3, the lift of the control device 3 is reduced, and the control device 3 descends. The space holding device of the present embodiment can not be provided with the directional elbow 38, but can use the inclined rotation of the valve flaps 332 arranged in the jet ports 34 to achieve the adjustment of the horizontal rotation and movement of the space holding device. The position state of the control device 3 can be changed by simultaneously changing the airflow transmitted from the conveying pipe 2. The embodiment of Figure 11 is also provided with the corrugated portion 39 at the bottom of the central cavity 30, the rotary joint 31 and the landing gear 8, and is provided with the fire extinguishing cylinder 7 at the top of the central cavity, and the working principle is the same as that of the embodiment of Figure 10, which will not be described again.

The electric motor 22 of the ducted fan 21 is started to drive the high-pressure gas into the delivery pipe 2. The inside of the delivery pipe 2 starts to inflate and is sprayed from the jet port 34 of the control device 3. With the increase of the flow of the sprayed gas, the control device 3 obtains enough lift to start to rise. The delivery pipe 2 is continuously stretched out from the inside of the storage cylinder 23 to reach the set height. Conversely, the control device 3 descends and spirals the delivery pipe 2 into the inside of the storage cylinder 23.

The lower end of the fire extinguishing tube communication pipe 91 is fixedly connected with the conveying pipe 2. The fire extinguishing tube 9 is provided with a fire extinguishing tube support 92 on the side of the fire extinguishing tube communication pipe 91. The fire extinguishing tube support 92 is made of rigid material.

[0068] Figure 21 is a schematic diagram of the top of an embodiment of the control device of the present application provided with a human body fixing device. The human body fixing device 10 is provided on the top of the control device 3. The human body fixing device 10 is used to fix the human body to the control device 3. The human body fixing device 10 shown in the figure is a structure similar to a shoe. The human body fixing device 10 can fix the feet of the human body. The human body stands above the control device 3. The control handle is used to control the hover device to operate through the control device 3. For example, the control handle is provided with a multi-axis potentiometer. The control handle transmits signals between the controller 35 on the control device 3 in a wired or wireless manner. The control handle controls the rotation of the control valve 33 and the power output of the ducted fan 21 of the high-pressure gas device 1. The control device 3 moves or hovers or ascends and descends. The human body moves or hovers or ascends and descends together with the control device 3. The human body can actively move the center of gravity to cooperate with the movement or hovering of the control device 3.

[0069] In the technical solution of the present application, the controller 35 is provided with an electronic circuit and corresponding software for automatically controlling the balance, so that the hovering device can run smoothly. The existing technology has a corresponding mature control module, such as a gyroscope, an acceleration sensor, and a gravity sensor, which are used to detect the position and motion state of the hovering device. The controller 3 is processed by the electronic circuit, and the output voltage and current are output to the corresponding rudder 333 to drive the corresponding rudder 333 to rotate or stop, change the gas flow of different gas injection holes 34, and thus change the running state of the hovering device. Such control technology has been widely used in the field of multi-rotor and fixed-wing unmanned aerial vehicle control, such as the rudder used to control the attitude of the rudder surface of the fixed-wing unmanned aerial vehicle. The difference between the two is that the valve shaft 331 of the present application is directly connected to the valve flap 332, and the rudder 333 is composed of a housing, a circuit board, a drive motor, and a position detection element. Its working principle is to receive signals from the controller 3, drive the motor through the IC on the rudder circuit board to start rotating, and transmit power to the valve flap 332 through the valve shaft 331 through the reduction gear. At the same time, the position detector sends back a signal to determine whether the positioning has been reached. In the present application, it is determined whether the valve flap 332 has reached the positioning. When the control device 3 is tilted or / and moved horizontally due to wind force, the control device 3 automatically detects and adjusts the valve flap 332 to make the high-pressure gas spray towards the direction of the tilt or / and movement to make the control device 3 tend to be in a balanced position, and the delivery pipe 2 tends to be in a vertical state. Based on the above technology, the control device 3 of the technical solution of the present application can hover and move together with the high-pressure gas device 1 on the ground when the trailer 4 moves position. The control device 3 does not need to take off and land frequently, so it is convenient for the hovering device to move a short distance. Those skilled in the art can implement the use of materials according to the technical solution of the present application and the existing technology.
