Description
The technical field is as follows:
the invention provides a device for towing and releasing a loop rope of an unmanned aerial vehicle, and belongs to the field of safety engineering.
Background art:
as the economy continues to grow and the number of high-rise buildings continues to increase, the risk of disasters, such as fires, associated with high-rise buildings also increases. When a high-rise fire disaster occurs, a rope is erected between the roof of the high-rise building in the fire disaster and the roof of the adjacent safe high-rise building to convey personnel and materials, and the rope can play an active role in rescuing the high-rise fire disaster. Permanent ropes can not be erected between roofs of high buildings under normal conditions, and the permanently erected ropes are difficult to maintain and overhaul due to long-term rain and sunshine, so that the use safety during disaster rescue cannot be guaranteed. Therefore, it is generally necessary to temporarily install a rope between the roofs of two high buildings in case of a disaster in the high buildings. The invention relates to an automatic rope erecting system between high buildings (patent number: 201910668991.3, granted publication number CN 110354408B), which can automatically and effectively erect temporary ropes between high buildings. The system of the invention comprises a vertical post arranged on the roof and an unmanned aerial vehicle for conveying ropes; the top of the upright post is smooth and blunt, the middle of the upright post is nested with a pulley, and the diameter of the outer ring of the pulley is slightly smaller than that of the upright post; a horn-shaped guide rail is arranged below the unmanned aerial vehicle body and used for guiding the unmanned aerial vehicle to hover above the upright post; a circle of hooks is arranged around the horn-shaped guide rail below the unmanned aerial vehicle body, a rope to be erected surrounds the horn-shaped guide rail and is hung on the hooks, and the hooks are retracted after the rope is hung so as to ensure that the rope cannot fall off from the unmanned aerial vehicle in the conveying process; when the unmanned aerial vehicle hovers above the upright post, the hook is opened to enable the rope sleeve to fall down to sleeve the upright post, and further slide down to sleeve the pulley at the lower end of the upright post; so that the erected ropes can reciprocate around the pulleys to drag and convey personnel and materials between the roofs of the two high buildings by the ropes. In the system, a horn-shaped guide rail below the unmanned aerial vehicle body is a key for guaranteeing that the loop rope is accurately put on the roof upright post; the horn-shaped guide rail is fixed on the unmanned aerial vehicle and cannot move; for the convenience of hitching the roof stud, the size and weight of the guide rail will not be too small relative to the drone because the guide rail extends downwardly from the drone fuselage, so the center of gravity of the drone with the guide rail is not in the plane of the engine mounting of the propeller of the drone, but is much lower than the plane of the engine mounting of the propeller. The gravity center of the unmanned aerial vehicle is far away from the mounting plane of the spiral wing engine, which causes great difficulty to the flight control of the unmanned aerial vehicle; particularly, the invention has a design that the casing rope is hung on the lower end edge of the horn-shaped guide rail, so that the hung casing rope generates a large pitching torque to the unmanned aerial vehicle through the horn-shaped guide rail, and the unmanned aerial vehicle is difficult to keep flying or hovering unless the power of a spiral wing engine of the unmanned aerial vehicle is large enough. The large size and high cost of the engine mean that the engine is large, which is not favorable for the popularization and application of the patent. In addition, the system of the invention is specially provided with a hook in order to ensure that the loop rope cannot accidentally fall off in the flight process of the unmanned aerial vehicle; when the loop rope is conveyed, the hook is retracted so as to clamp the loop rope and prevent the loop rope from falling off; when the sleeve rope is thrown to the top upright post, the hook is opened, and the sleeve rope slides down under the action of self gravity and is sleeved on the top upright post. However, the retraction of the hook means a cumbersome operation step, which is not beneficial to the operation and use of the system of the invention. Finally, in order to accurately sleeve the sleeve rope on the top upright post, the system mainly depends on the control of the spiral wing engine of the unmanned aerial vehicle, so that the unmanned aerial vehicle can accurately hover above the top upright post, and the control difficulty of related flight is small.
The invention provides a device for dragging and releasing a loop rope of an unmanned aerial vehicle, which can realize the purpose of blocking and releasing the loop rope without a hook through a group of movable horn-shaped guide rails; the center of gravity of the whole unmanned aerial vehicle system can be close to the mounting plane of the spiral wing engine during flying, so that the unmanned aerial vehicle can be controlled to fly conveniently; when preparing to put in the noose to the roof stand, open and shut through control loudspeaker form guide rail, just can guide unmanned aerial vehicle accuracy to hover directly over the roof stand to guarantee that the noose is put in successfully.
The invention content is as follows:
the invention aims to provide a device for pulling and throwing casing ropes of an unmanned aerial vehicle, and aims to solve the technical problem that the unmanned aerial vehicle is difficult to control due to the fact that the casing ropes are pulled and stumbled and the center of gravity of an unmanned aerial vehicle system is far away from a spiral wing engine mounting plane when the unmanned aerial vehicle is used for pulling and throwing the casing ropes.
The invention relates to a device for dragging and releasing a loop rope of an unmanned aerial vehicle, which mainly comprises the following parts: spokes, a foldable link, a strut, a shaft, and a driver. Foldable connectors are connected between every two adjacent spokes, and the spokes and the foldable connectors form a movable horn-shaped guide rail, namely, the horn-shaped guide rail can be opened and closed like an umbrella. The driver is installed below the unmanned aerial vehicle fuselage. Branch encircles and distributes around the driver, fixes in unmanned aerial vehicle fuselage below. The spoke is connected to the branch of fixing in unmanned aerial vehicle fuselage below through the pivot, and every spoke links a branch. Each spoke is divided into two sections by taking the rotating shaft as a boundary; one section is long and the other section is short; the ends of the long sections of the spokes are referred to as the long spoke ends, and the ends of the short sections of the spokes are referred to as the short spoke ends. The short ends of the spokes are connected to the driver. The driver can drive the short end of the connected spoke to move up and down, so that the spoke rotates around the rotating shaft in a pitching manner, and the opening and closing of the horn-shaped guide rail are controlled.
When the driver drives the short end of the connected spoke to move downwards, the long end of the spoke rotates upwards around the rotating shaft, so that the trumpet-shaped guide rail is opened. When the driver drives the short end of the connected spoke to move upwards, the long end of the spoke rotates downwards around the rotating shaft, so that the horn-shaped guide rail is folded.
When unmanned aerial vehicle need draw and transport the noose, encircle the periphery of the cover at that round branch of unmanned aerial vehicle fuselage below with the rope, then the driver drives loudspeaker form guide rail and opens completely, and unmanned aerial vehicle fuselage below is pressed close to the long end of spoke, blocks the noose in the branch periphery. When the unmanned aerial vehicle drags the loop rope to fly, the horn-shaped guide rail keeps a completely opened state, so that the loop rope is clamped to prevent the loop rope from falling; when the unmanned aerial vehicle needs to put in the loop rope, the driver drives the horn-shaped guide rail to be completely folded, so that the loop rope slides down under the action of self gravity and is sleeved on a specified object; therefore, extra hooks are not needed for pulling and putting the loop rope, and the movable horn-shaped guide rail plays a role in hooking. When unmanned aerial vehicle need hover appointed object top, the driver drives tubaeform guide rail and closes gradually and receive, receive that receipts in-process tubaeform guide rail meets the produced reaction force of this object and can drive unmanned aerial vehicle and remove to this object top to can avoid can only controlling the difficulty that the spiral wing engine realized hovering appointed object top.
In the invented device, the foldable links connected between adjacent spokes can be fan-shaped flexible fabric, so that when the trumpet-shaped guide rail is fully opened, it looks like an open umbrella. When the unmanned aerial vehicle has flown to approach to the designated object, the planar horn-shaped guide rail can smoothly guide the unmanned aerial vehicle to hover above the designated object, but the flight hindering force caused by the planar horn-shaped guide rail is large.
In the invented device, the foldable connectors connected between adjacent spokes can be in a rope net structure, so that when the trumpet-shaped guide rail is fully opened, the device is like a spider net. The horn-shaped guide rail of the rope net structure has small flight resistance, but the horn-shaped guide rail of the rope net structure is easily hung and blocked by foreign matters.
When the unmanned aerial vehicle flies by pulling the sleeve rope, the sleeve rope is usually tightly pressed on the supporting rod under the action of the pulling force; when unmanned aerial vehicle is drawn and is being hung the noose and fly to the distance, the noose can slide round branch, and the tight state of pressing between noose and the branch can produce very big frictional force, and this frictional force can produce a moment of torsion to unmanned aerial vehicle to cause the difficulty of controlling unmanned aerial vehicle. In the device, each support rod fixed below the unmanned aerial vehicle body is provided with a rotating ring. The swivel can reduce the friction between rope and the branch to effectively avoid controlling the difficult situation to unmanned aerial vehicle because of the frictional force moment of torsion causes.
In order to further reduce the torque caused by the friction between the loop rope and the unmanned aerial vehicle in the flying process of the unmanned aerial vehicle, the back surface of the long end of the spoke, namely the surface of the spoke corresponding to the outer side of the horn-shaped guide rail, can be provided with a universal roller. When unmanned aerial vehicle drags the flight of set rope, universal gyro wheel can reduce the friction in rope and the loudspeaker form guide rail outside. Simultaneously, when unmanned aerial vehicle need put in the noose, universal gyro wheel also is favorable to the noose landing to overlap on appointed object. However, the installation of the universal rollers increases the production cost and the structural complexity of the inventive device.
In the invented device, the driver can drive the spokes to rotate around the rotating shaft in a pitching mode in various modes.
The first mode is as follows: the spokes are connected to one end of the driver, namely the short ends of the spokes are provided with guide grooves, and the guide groove at the short end of each spoke is inserted with a connecting rod fixed on the driver. When the driver moves up and down, the connecting rod can slide in the guide groove at the short end of the spoke, so that the spoke is driven to rotate around the rotating shaft in a pitching manner.
The second mode is as follows: the lower part of the driver is provided with a guide groove corresponding to the spoke, one end of the spoke close to the driver, namely the short end of the spoke is fixed with a connecting rod, and the connecting rod is inserted in the guide groove at the lower part of the driver. When the driver moves up and down, the connecting rod fixed at the short end of the spoke can be forced to slide in the guide groove at the lower part of the driver, so that the spoke is driven to rotate around the rotating shaft in a pitching manner.
The third mode is as follows: the lower part of the driver is provided with a movable connecting rod at a position corresponding to the spoke, one end of the movable connecting rod is connected to the driver through a movable bolt, and the other end of the movable connecting rod is connected to one end, close to the driver, of the spoke, namely the short end of the spoke, through the movable bolt. When the driver moves up and down, the movable connecting rod rotates in a pitching mode between the driver and the short end of the spoke through the movable bolts at the two ends of the movable connecting rod, and therefore the spoke is driven to rotate around the rotating shaft in a pitching mode.
The fourth mode is that: in the invented device, the end of the spoke close to the driver, i.e. the short end of the spoke and the driver are not connected with a transmission part. When the driver moves downwards, the lower end of the driver directly forces the long end of the spoke to rotate upwards around the rotating shaft by physically pushing the short end of the spoke, so that the horn-shaped guide rail is opened; when the driver moves upward, since the long ends of the spokes are heavier than the short ends of the spokes, the spokes rotate the long ends of the spokes downward about the rotary shafts by their own weight, so that the trumpet-shaped guide rails are collapsed.
In the first three modes that the driver drives the spokes to rotate around the rotating shafts in a pitching mode, the driver has direct control capability on the opening and closing of the horn-shaped guide rails. In the fourth mode, the driver only has direct control capability on the opening of the horn-shaped guide rail, but the driver does not have direct control capability on the closing of the horn-shaped guide rail, for example, if the spoke rotates and is blocked due to the corrosion of the rotating shaft, even if the driver moves upwards, the horn-shaped guide rail cannot be closed, so that the loop rope cannot smoothly slide and is sleeved on a specified object; however, this disadvantage can be overcome by using resilient collapsible links between the spokes, i.e. when the actuator moves upwards, the contraction force of the resilient collapsible links together with the spokes' own weight forces the long ends of the spokes to rotate downwards about the rotation axis, whereby the trumpet shaped guide rails collapse. Compared with the first three modes that the spoke is driven by the driver to rotate around the rotating shaft in a pitching mode, the fourth mode is the simplest in structure, and the manufacturing cost and the maintenance cost are the lowest.
The various components of the inventive apparatus may be designed with appropriate materials, shapes, sizes, numbers, colors, and placement positions. For example, the spokes may not be straight, but have a bending amplitude; the spokes are bent outwards, so that the guide rail is in a horn shape which is turned outwards and tilted, and therefore when the unmanned aerial vehicle drags the loop rope to fly, the loop rope can be clamped more firmly by the horn-shaped guide rail, and the loop rope is prevented from falling off; spoke incurving can be so that the guide rail becomes the loudspeaker form of inside shrink to when unmanned aerial vehicle need put in the noose, be favorable to more that the noose landing overlaps to appointed object on. The more the spokes are, the more the support rods fixed below the unmanned aerial vehicle body are, the more the swivel rings on the support rods are, the more the universal rollers on the back of the long ends of the spokes are, and the more the pulling and putting-in of the loop ropes are facilitated; but the weight and cost of the device will also increase accordingly.
The device for the unmanned aerial vehicle to hitch and release the loop rope has the following beneficial effects: the device can realize the purpose of clamping and throwing the loop rope without a hook, thereby simplifying the structure and reducing the cost; the device can ensure that the gravity center of the whole unmanned aerial vehicle system is close to the mounting plane of the spiral wing engine during the flight, thereby being convenient for controlling the unmanned aerial vehicle to fly; the device can control the unmanned aerial vehicle to accurately hover above a specified object by controlling the opening of the horn-shaped guide rail, so that the success of putting the loop rope is ensured.
