Description

Technical Field

[0001] This utility model belongs to the field of emergency power supply equipment technology, and relates to a flight power supply device for emergency rescue. Background Technology

[0002] In natural disaster relief scenarios (such as earthquakes, typhoons, and floods), power supply is a core requirement for ensuring the operation of life detection, medical equipment, communication systems, and large rescue machinery. Traditional diesel generator sets and power supply vehicles rely on road transportation, but disasters often cause road damage and bridge collapses, preventing equipment from reaching the scene in a timely manner. Existing technologies, such as drones and mobile power supply devices, have the following limitations:

[0003] 1. Drones: Short flight time (usually <1 hour), low payload capacity (<50kg), unable to carry high-power generator sets;

[0004] 2. Mobile power supply vehicle: Relies on ground transportation, has limited off-road capability, and cannot cross complex terrain;

[0005] 3. Temporary power supply solution: such as insufficient capacity of lithium battery packs to support long-term high-power operation.

[0006] For example, patent CN202310636515.X discloses a flight emergency power supply system, including: an aviation hybrid power unit that uses fuel as power to achieve electric power output; a switching unit connected to the aviation hybrid power unit; an aircraft propulsion unit connected to the switching unit; and an emergency power supply unit connected to the switching unit. The switching unit has a first state where it switches to a connection between the aviation hybrid power unit and the aircraft propulsion unit, where the aviation hybrid power unit cooperates with the aircraft propulsion unit for vertical takeoff and landing and in-flight flight; and a second state where it disconnects the connection between the aviation hybrid power unit and the aircraft propulsion unit, switches to a connection between the aviation hybrid power unit and the emergency power supply unit, where the emergency power supply unit outputs emergency electrical power on the ground. This system sets the emergency power supply unit to a vertical takeoff and landing and controllable flight state, unrestricted by roads, but it cannot be moved on the ground, limiting its mobility. Utility Model Content

[0007] The purpose of this invention is to provide a flight power supply device for emergency rescue, in order to solve the problem that power generation equipment cannot be quickly delivered to disaster sites due to road damage.

[0008] To achieve the above objectives, the basic solution of this utility model is: a flight power supply device for emergency rescue, comprising a flight mechanism, a driving mechanism, and a power generation module;

[0009] The flight mechanism includes a propeller and a first power source for controlling the rotation of the propeller, the propeller being mounted on top of the power generation module;

[0010] The driving mechanism includes all-terrain tires and a second power source for controlling the rotation of the all-terrain tires, with the all-terrain tires located at the bottom of the power generation module.

[0011] The working principle and beneficial effects of this basic solution are as follows: This technical solution installs the flight mechanism and the driving mechanism in corresponding positions on the power generation module, so as to drive the power generation module to fly or move on the ground when needed.

[0012] The flight mechanism relies on a propeller and a primary power source, similar to the structure of a drone or helicopter. The primary power source activates, controlling the propeller's rotation to provide flight propulsion. The driving mechanism utilizes all-terrain tires and a secondary power source, similar to a mobile vehicle structure. The secondary power source activates, controlling the all-terrain tires' rotation to move the power generation module on the ground.

[0013] Furthermore, the propeller is provided with one or more sets, and the all-terrain tire is provided with at least three sets.

[0014] Setting the appropriate number of propellers and all-terrain tires facilitates use.

[0015] Furthermore, it also includes a refueling mechanism, which comprises an aircraft, a refueling storage tank, and a refueling nozzle;

[0016] The top of the power generation module is equipped with a refueling port, the refueling storage box is installed on the aircraft, the inlet end of the refueling gun is connected to the refueling storage box, and the outlet end of the refueling gun can be aligned and snapped into the refueling port.

[0017] When the power generation module needs refueling, the aircraft is started, which moves the end of the refueling gun to engage with the refueling port on the top of the power generation module, thereby refueling.

[0018] Furthermore, the oil replenishment mechanism also includes an oil level sensor, an oil level comparator, and a GPS positioning module;

[0019] The oil level sensor is installed in the oil tank of the power generation module. The output terminal of the oil level sensor is connected to the first input terminal of the oil level comparator. The second input terminal of the oil level comparator is connected to the oil level threshold memory. The output terminal of the oil level comparator is connected to the control terminal of the aircraft and the start terminal of the GPS positioning module.

[0020] The GPS positioning module is installed on the power generation module, and the position signal output terminal of the GPS positioning module is connected to the signal input terminal of the aircraft.

[0021] An oil level sensor is installed in the fuel tank of the generator module to collect the oil level information and transmit it to the oil level comparator. The oil level comparator compares the oil level information collected by the oil level sensor with the oil level threshold value stored in the oil level threshold memory. If the collected oil level information is lower than the oil level threshold value stored in the oil level threshold memory, it means that the oil level in the generator module's fuel tank is too low and needs to be replenished.

[0022] At this time, the fuel level comparator outputs a control signal to the control terminal of the aircraft and the start terminal of the GPS positioning module, starting the aircraft and the GPS positioning module.

[0023] The GPS positioning module is activated to obtain the location information of the power generation module and transmit it to the aircraft, so that the aircraft can fly to the power generation module based on the location information.

[0024] Furthermore, the refueling mechanism also includes a first magnetic suction component and a second magnetic suction component. The first magnetic suction component is located at the bottom of the aircraft, and the second magnetic suction component is located on the outside of the refueling port. The first magnetic suction component and the second magnetic suction component can be magnetically connected.

[0025] The first and second magnetic suction components are provided so that when the aircraft is docked on the power generation module, it can be magnetically connected to the power generation module, which enhances the stability of the connection between the refueling port and the refueling gun during refueling.

[0026] Furthermore, it also includes a support mechanism, which comprises at least two sets of electrically operated support rods;

[0027] The electric support rod is vertically arranged and installed at the bottom of the power generation module.

[0028] Using an electric support rod, the power generation module is automatically leveled after being placed on the ground, ensuring the stability of power generation.

[0029] Furthermore, it also includes a cable winch, the input end of which is connected to the power output end of the power generation module, and the output end of the cable winch can be connected to external rescue operation equipment.

[0030] The cable winch has a built-in 50-meter flexible cable, which is released to the rescue operation equipment via an electric winch.

[0031] Furthermore, it also includes an energy storage module, which is installed on the power generation module, and the power supply end of the energy storage module is connected to the flight mechanism and the driving mechanism respectively.

[0032] An energy storage module is installed for power supply during flight, walking, and low-load operation. Attached Figure Description

[0039] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0040] In the description of this utility model, it should be understood that the terms "longitudinal", "lateral", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0041] In the description of this utility model, unless otherwise specified and limited, it should be noted that the terms "installation", "connection" and "linking" should be interpreted broadly. For example, they can refer to mechanical or electrical connections, or internal connections between two components. They can be direct connections or indirect connections through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms according to the specific circumstances.

[0042] This utility model discloses a flight power supply device for emergency rescue, which solves the problem that power generation equipment cannot be quickly reached at disaster sites due to road damage, and improves adaptability to complex terrain.

[0043] like Figure 1 and Figure 2 As shown, the flight power supply unit for emergency rescue includes a flight mechanism, a travel mechanism, and a power generation module 102. The power generation module 102 can be a lightweight diesel generator set (aluminum alloy casting), with a high speed of 3000 rpm and an integrated 8-hour fuel tank (plastic material); or a high-speed 3000 rpm 2-pole synchronous permanent magnet generator, made of cast aluminum, with copper-clad aluminum coils. Due to the use of high-speed and lightweight materials, taking a 50kW generator as an example, compared with a conventional 1500 rpm generator set, the overall volume is reduced by 40% and the overall weight is reduced by 50%. However, at the same time, the high speed leads to a decrease in engine torque and a 30% reduction in transient performance. It is suitable for emergency rescue environments where the requirements for power transient performance quality are not high.

[0044] The flight mechanism includes a propeller 101 and a first power source (such as an electric motor) that controls the rotation of the propeller 101. The propeller 101 is mounted on top of the power generation module 102 via a rotating shaft. One end of the rotating shaft is connected to the central shaft of the propeller 101 (e.g., by welding, bonding, riveting, or pin connection), and the other end is connected to the output shaft of the first power source (e.g., by welding or pin connection). The first power source is mounted (e.g., by welding, bonding, or riveting) on ​​the power generation module 102. The flight mechanism relies on the propeller 101 and the first power source, similar to a drone or helicopter. When the first power source starts, it controls the rotation of the propeller 101, providing flight propulsion. For example, four electric motors can drive the ducted propeller 101 for vertical takeoff and landing (VTOL). Alternatively, a turboshaft engine can be used instead of the electric motors.

[0045] The driving mechanism includes all-terrain tires 105 and a second power source (such as a motor) to control the rotation of the all-terrain tires 105. The all-terrain tires 105 are located at the bottom of the power generation module 102. Preferably, the propellers 101 are provided in one or more sets (such as two sets, three sets, four sets, etc.). If four sets of propellers 101 are provided, the propellers 101 are installed at the four top corners of the power generation module 102, and the all-terrain tires 105 are provided in at least three sets (or four sets). The driving mechanism utilizes the all-terrain tires 105 and the second power source, similar to a mobile vehicle structure. When the second power source is activated, it controls the rotation of the all-terrain tires 105, driving the power generation module 102 to move on the ground.

[0046] The flight mechanism and driving mechanism are installed in corresponding positions on the power generation module 102, thereby enabling the power generation module 102 to fly or move on the ground when needed. Vertical takeoff and landing capability overcomes terrain obstacles, reducing arrival time by 80%.

[0047] Preferably, the power generation module 102 may also be equipped with a silencer (to reduce noise), a socket box, a control box, a tow bar, and other mechanisms.

[0048] In a preferred embodiment of this invention, the flight power supply device for emergency rescue also includes a refueling mechanism, such as... Figure 3 and Figure 4 As shown, the refueling mechanism includes the aircraft, the refueling storage tank 202 (carbon fiber shell), and the refueling gun 206.

[0049] The top of the power generation module 102 is equipped with a refueling port 106, which is connected to the fuel tank of the power generation module 102. A refueling storage tank 202 is mounted on the aircraft. The inlet end of the refueling nozzle 206 is connected to the refueling storage tank 202, and the outlet end of the refueling nozzle 206 can be aligned and snapped into place with the refueling port 106. In-flight refueling can utilize a hose-cone system instead of a rigid refueling nozzle. An oil pipe retraction tray 205 is provided, equipped with a 360-degree anti-tangle swivel joint connected to the oil pipe at the outlet of the refueling storage tank 202, ensuring unobstructed fuel flow during hose retraction and extension. The aircraft includes a skid landing gear 204 and a top propeller 201 (or multiple sets, such as four sets) mounted on top of the skid landing gear 204. The refueling storage tank 202 is mounted on the skid landing gear 204. High-density lithium battery modules such as 203 can also be installed on the skid landing gear 204 for power supply.

[0050] When the power generation module 102 requires refueling, the aircraft is activated, causing the end of the refueling gun 206 to move and engage with the refueling port 106 on the top of the power generation module 102, thus refueling. The lightweight generator set with refueling mechanism supports 50kW uninterrupted power output. The aircraft can be manually controlled or an intelligent aircraft, such as existing drones that integrate a GPS module into their flight controller (e.g., Pixhawk, DJI A3).

[0051] In a preferred embodiment of this invention, the oil replenishment mechanism further includes an oil level sensor (such as VDO 360-009, TIPGA900, etc.), an oil level comparator, and a GPS positioning module. The comparator in this invention can be a digital comparator or an analog comparator, such as LM324, LM339, etc. A digital-to-analog converter module (such as AK4021, etc.) can be set at the input of the comparator as needed to convert the signal.

[0052] The fuel level sensor is installed in the fuel tank of the power generation module 102. The output terminal of the fuel level sensor is electrically connected to the first input terminal of the fuel level comparator. The second input terminal of the fuel level comparator is electrically connected to the fuel level threshold memory. The output terminal of the fuel level comparator is electrically connected to the control terminal of the aircraft and the start terminal of the GPS positioning module.

[0053] The GPS positioning module is installed on the power generation module 102, and the position signal output terminal of the GPS positioning module is electrically connected to the signal input terminal of the aircraft.

[0054] An oil level sensor is installed in the oil tank of the generator module 102 to collect the oil level information and transmit it to the oil level comparator. The oil level comparator compares the oil level information collected by the oil level sensor with the oil level threshold value stored in the oil level threshold memory. If the collected oil level information is lower than the oil level threshold value stored in the oil level threshold memory, it means that the oil level in the oil tank of the generator module 102 is too low and needs to be replenished.

[0055] At this time, the fuel level comparator outputs a control signal to the control terminal of the aircraft and the start terminal of the GPS positioning module, starting the aircraft and the GPS positioning module.

[0056] The GPS positioning module is activated to acquire the location information of the power generation module 102 and transmit it to the aircraft, so that the aircraft can fly towards the power generation module 102 based on the location information. Utilizing GPS positioning and satellite communication technology, it sends location signals and refueling signals when the fuel level is low. For example, existing patent CN201520697780.X mentions an aircraft with a precision landing system that performs fixed-point flight based on location information.

[0057] More preferably, the refueling mechanism also includes a first magnetic attractor and a second magnetic attractor (such as a strong magnet). The first magnetic attractor is located at the bottom of the aircraft, and the second magnetic attractor is located on the outside of the refueling port 106. The first magnetic attractor and the second magnetic attractor can be magnetically connected.

[0058] The first and second magnetic suction components are provided so that when the aircraft is docked on the power generation module 102, it can be magnetically connected to the power generation module 102, which enhances the stability of the connection between the refueling port 106 and the refueling gun 206 during refueling.

[0059] In a preferred embodiment of this utility model, the flight power supply device for emergency rescue further includes a support mechanism, which comprises at least two sets of electric support rods 104. The electric support rods 104 are vertically arranged and installed at the bottom of the power generation module 102. The electric support rods 104 utilize a DC motor (e.g., 12V / 24V) or a stepper motor, converting the motor's rotational motion into linear telescopic motion via a screw, gearbox, or hydraulic system. This can be controlled via a button, wireless remote control, or smart terminal (e.g., a mobile app). By adjusting the length of the electric support rods 104, the fuselage (i.e., the power generation module 102) is leveled, and then the power generation module 102 is activated to supply power to the rescue equipment.

[0060] For example, four sets of electric support rods 104 are set up to automatically level the generator module 102 after it is placed on the ground, ensuring the stability of power generation.

[0061] All-terrain tires 105 + electric support poles 104, adaptable to muddy and sloping terrain.

[0062] In a preferred embodiment of this utility model, the flight power supply device for emergency rescue further includes a cable winch 103. The input end of the cable winch 103 is connected to the power output end of the power generation module 102, and the output end of the cable winch 103 can be connected to external rescue operation equipment (such as snap-fit, plug-in, etc.).

[0063] The cable winch 103 has a built-in 50-meter flexible cable, which is released to the rescue operation equipment via an electric winch.

[0064] In a preferred embodiment of this utility model, the flight power supply device for emergency rescue further includes an energy storage module 107, which is installed on the power generation module 102. The power supply terminals of the energy storage module 107 are electrically connected to the flight mechanism and the driving mechanism, respectively.

[0065] The energy storage module 107 can use a high-energy-density lithium battery pack for power supply during flight, walking, and low-load operation. With lithium battery auxiliary power supply, noise is reduced to below 50dB during nighttime rest.
