Technical Field

The invention relates to the technical field of balloons, in particular to a strong wind-resistant balloon carrying device.

Background

The balloon carrying device is a device for carrying goods in the air by utilizing the buoyancy of a balloon. When wind blows through the balloon, the pressure of the windward side of the balloon is increased, and the pressure potential energy of the surface of the balloon is increased. After wind power reaches a certain strength, the phenomenon that the balloon mooring rope is broken and the balloon is blown flat can occur, and the flying speed of the balloon carrying device is also possibly too high, which can cause safety accidents.

Compared with the prior art, the invention has the following technical effects:

according to the invention, the rotation of the floating body is accelerated by arranging the turbulent flow structure, and the pressure potential energy received by the floating body after the rotation kinetic energy of the floating body is increased is reduced, so that the wind resistance of the floating body is improved. Because the suspension body is suspended below the floating body, the gravity center of the integral structure (called as a rotor) formed by the floating body and the suspension body is inclined downwards, and the stability is strong. When the rotor rotates to a certain speed, the gyro effect enables the rotation of the rotor to be more stable, and the wind resistance is further improved. Because the suspension body is connected with the load-carrying structure in a rotating mode instead of a fixed mode, when the suspension body rotates, the rotating speed of the load-carrying structure is always smaller than that of the suspension body, and therefore the goods carried by the load-carrying structure are kept stable as far as possible, and damage to the goods is avoided.

Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

The invention aims to provide a strong wind-resistant balloon carrying device, which is used for improving the stability of the balloon carrying device in a strong wind environment and avoiding safety accidents.

In order to make the aforementioned objects, features and advantages of the present invention comprehensible, embodiments accompanied with figures are described in further detail below.

As shown in fig. 1, the present embodiment provides a balloon-carrying device 100 with strong wind resistance, which includes a floating body 1, a spoiler structure, a suspension body, and a load-carrying structure.

Wherein, the floating body 1 is a balloon or a plurality of fixedly connected balloons and is used for providing buoyancy. The turbulence structure is fixed on the outer side of the floating body 1 and is provided with a windward surface for increasing the windward area of the floating body 1, so that the rotation of the floating body 1 is accelerated when the wind is received. The windward side has a vertical projection, namely the windward side is not a horizontal plane, so that when the turbulent flow structure is windy, the acting force of wind on the turbulent flow plate 2 is not the direction of a plumb, and the acting force of wind on the turbulent flow plate 2 can always apply a rotating moment on the floating body 1. The pendant body is connected with the floating body 1 and is positioned below the floating body 1. The load-carrying structure is used for carrying cargos and is positioned below the pendant body. The load-bearing structure is rotatably connected with the suspension body, and the rotating shaft is in the plumb direction.

The working principle of the strong wind-resistant balloon carrier 100 of the present embodiment is as follows:

as shown in fig. 2-3, when the air flow passes through the curved convex surface, the air flow changes the moving direction to continue flowing, and takes away part of the air behind the convex surface through the adsorption effect, so that a low-pressure area is formed behind the convex surface, which adversely affects the direction of the air flow, and the air flow flows around the convex surface, which is the coanda effect. When the convex surface is the floating body 1, the air flow flows around the floating body 1, and the floating body 1 is driven to rotate by the pressure difference between the windward side and the leeward side of the floating body 1 and the friction force between the air flow and the floating body 1.

According to bernoulli's principle, kinetic energy + gravitational potential energy + pressure potential energy are constants, i.e., the mechanical energy of the fluid is conserved. When wind blows over the floating body 1, the pressure of the wind borne by the windward side of the floating body 1 is increased, so that the surface pressure potential energy of the floating body 1 is increased. When certain wind power is reached, the mooring rope of the floating body 1 is pulled off and the floating body 1 is blown flat, or the flying speed of the floating body 1 is too high due to wind blowing, and the like, so that safety accidents are caused.

Based on the coanda effect described above, the floating body 1 is rotated when wind blows over the floating body 1. Then, according to the bernoulli principle, when wind blows over the floating body 1, the gravitational potential energy of the floating body 1 is unchanged, a part of wind energy generates pressure potential energy, and a part of wind energy is converted into rotational kinetic energy of the floating body 1. After the rotational kinetic energy of the floating body 1 is increased, the received pressure potential energy is reduced, thereby improving the wind resistance of the floating body 1. Tests show that after the floating body 1 rotates under the action of wind, the borne pressure potential energy can be reduced by about 50%.

In this embodiment, the rotation of the floating body 1 is further accelerated by providing the spoiler structure. The turbulence structure enables the floating body to have a larger convex part, so that on one hand, the area of the windward side of the floating body is increased, and the floating body bears larger wind power to apply larger rotating moment to the floating body; on the other hand, the pressure difference between the windward side and the leeward side of the spoiler structure makes the floating body 1 more easily rotated by wind.

Because the suspension body is hung below the floating body 1, the gravity center of the integral structure (called as a rotor) formed by the floating body 1 and the suspension body is lower. The axis direction of rotor is the plummet direction, even briefly deviate from the plummet direction, because the focus is inclined to the lower, also can adjust back fast, and stability is stronger. When the rotor rotates to a certain speed, the gyro effect enables the rotation of the rotor to be more stable, and the wind resistance is further improved.

Since the suspended body is connected to the load-carrying structure in a rotating manner, rather than in a fixed manner, the speed of rotation of the load-carrying structure is always less than that of the suspended body when the suspended body rotates. The lower the friction of the rotary connection here, the lower the rotational speed of the load-carrying structure, so that the goods carried by the load-carrying structure are kept stable as far as possible, avoiding damage to the goods.

There are many types of balloons, and those skilled in the art can select the type according to actual needs. In this embodiment, the balloon is a hot air balloon, and a person skilled in the art may select an inflation balloon (for example, filling hydrogen, helium, nitrogen, etc.) according to different actual needs.

In this embodiment, the suspension body is a first hanging basket 3, the first hanging basket 3 is connected with the floating body 1 through a rope body, and the first hanging basket 3 can bear a fire-adding device, a liquefied gas tank and the like used by a heat supply balloon. Other types of pendulums may be chosen by those skilled in the art, depending on the actual requirements, as long as they are capable of applying a downward force to the floating body 1.

In this embodiment, the spoiler structure is the spoiler 2, and those skilled in the art can select other structures such as a spoiler block and a spoiler ring, as long as the floating body 1 can be pushed to rotate under the action of wind. The number of the turbulent flow structures is preferably plural, and the plurality of the turbulent flow structures are preferably uniformly distributed in the circumferential direction of the floating body 1 (centered on the axis of the floating body 1 in the plumb direction).

It should be noted that when the air flow blows along the plane of symmetry of the floating body 1, the floating body 1 will not rotate. In order to solve this problem, in this embodiment, two plate surfaces of the spoilers 2 are different in shape, one plate surface is concave, the other plate surface is convex, and the convex surface of each spoiler 2 is oriented in the same direction (both clockwise or both counterclockwise) in the circumferential direction of the floating body 1. When the inner concave surface of the spoiler 2 at one side of the floating body 1 faces the wind, the outer convex surface of the spoiler 2 at the other side of the floating body 1 faces the wind. Because the concave plate surface has the effect of 'wind scooping', the wind power borne by the concave plate surface is larger, and therefore, even if airflow blows along the symmetrical center plane of the floating body, the floating body still rotates (the principle of the floating body is similar to that of a windmill).

In this embodiment, the load-carrying structure comprises a connecting member at the upper part and a second basket 5 at the lower part, the second basket 5 is used for carrying goods, and the connecting member is connected with the second basket 5 through a rope body. The connector is preferably a mooring clasp 4 to facilitate connection to the rope.

In order to reduce the friction at the rotary connection between the load-carrying structure and the suspension body, and thus reduce the rotation speed of the load-carrying structure and the load carried thereby as much as possible, in this embodiment the suspension body is rotatably connected to the load-carrying structure via a bearing 6, and the rotation axis of the bearing 6 is in the plumb direction. The type of the bearing 6 is various, and should be selected according to the actual load, and will not be described herein.

The rope in this embodiment may be a wire rope, or may be a wire rope, a chain, or other types of ropes as long as they can perform a connecting function.

In this embodiment, the application of the strong wind-resistant balloon carrier 100 includes, but is not limited to, emergency rescue, emergency communication, and power generation with an inflatable balloon.

The principle and the implementation mode of the present invention are explained by applying specific examples in the present specification, and the above descriptions of the examples are only used to help understanding the method and the core idea of the present invention; meanwhile, for a person skilled in the art, according to the idea of the present invention, the specific embodiments and the application range may be changed. In view of the above, the present disclosure should not be construed as limiting the invention.
