Description

Technical Field

[0001] The utility model relates to the technical field of high-altitude wind energy, in particular to a double-airbag balloon structure. Background Art

[0002] High-altitude wind energy has been developed for over 20 years. The new parachute-ladder high-altitude wind energy generation technology consists of three parts: aerial equipment, ground equipment, and a control system. By controlling the opening and closing of the parachute assembly, the parachute assembly moves up and down in a circular motion, which in turn drags the ground-based generator to generate electricity, thereby converting wind energy into mechanical energy, which then drives the generator set to generate electricity. High-altitude wind speeds are high and their density is generally tens to hundreds of times higher than that of ground wind energy. By placing a balloon in the air and using a working parachute to drive a ground friction drum, the tension drives the mechanical equipment, converting wind energy into mechanical energy, and then from mechanical energy into electrical energy. An auxiliary hoist is used. After the hoist is activated and the rope release button is pressed, the helium balloon begins to ascend. The main cable is then attached to the balloon and ascends. During the launch and power generation process, the wind speed suddenly increases, and the helium gas concentrates in the upper half of the balloon, while the lower half deflates, increasing the wind-exposed surface. This increases the sway of the main cable, causing the balloon to sway significantly during operation and easily rub against the ground. Over time, this can damage the balloon or cause the cable to break, allowing the helium balloon to escape. Utility Model Content

[0003] In response to the shortcomings of the existing technology, the utility model provides a double-airbag balloon structure, which solves the problem that helium gas is concentrated in the upper part of the balloon, the lower part of the balloon becomes deflated, the wind-exposed surface increases, and the main cable swings more, causing the balloon to swing more during operation and easily rub against the ground. Over time, the balloon may be damaged or the cable may break, causing the helium balloon to escape.

[0004] To achieve the above objectives, the present invention is implemented through the following technical solutions: a double-airbag balloon structure, comprising an outer airbag, a mounting seat mounted on the bottom end of the outer airbag, an inner airbag mechanism mounted on the mounting seat, and a fixing mechanism disposed between the inner airbag mechanism and the mounting seat;

[0005] The internal airbag mechanism includes a first internal airbag part, a second internal airbag part, a third internal airbag part and a fourth internal airbag part.

The bottom ends of the first internal airbag part, the second internal airbag part, the third internal airbag part and the fourth internal airbag part are all fixedly connected to connecting pipes, the ends of the four connecting pipes are connected to a main pipe, the end of the main pipe is connected to an electric valve, the bottom end of the electric valve is connected to a three-way pipe, and both ends of the bottom of the three-way pipe are connected to an air supply fan.

[0006] Preferably, the bottom end of the outer airbag is fixedly connected to an air intake pipe, the bottom end of the air intake pipe is fixedly installed inside the mounting seat, and the end of the air intake pipe is connected to a pressure relief valve, so that the outer airbag can be inflated and the internal air pressure of the outer airbag can be prevented from being too high.

[0007] Preferably, the first inner airbag portion, the second inner airbag portion, the third inner airbag portion and the fourth inner airbag portion are respectively fixedly mounted on the inner wall of the outer airbag, and the first inner airbag portion, the second inner airbag portion, the third inner airbag portion and the fourth inner airbag portion are arranged in the lower half of the outer airbag, so that they can support the lower half of the outer airbag and prevent the outer airbag from deformation.

[0008] Preferably, the first inner airbag portion conflicts with the conflict surfaces of the second inner airbag portion and the fourth inner airbag portion through a conflict surface, and the third inner airbag portion conflicts with the conflict surfaces of the second inner airbag portion and the fourth inner airbag portion through a conflict surface, which can increase the mutual support between the four inner airbag portions and improve the anti-deformation effect.

[0009] Preferably, the first inner airbag part, the second inner airbag part, the third inner airbag part and the fourth inner airbag part are connected through a connecting pipe and a main pipe, and the air supply fan is configured as a brushless fan, so that the air supply fan can operate more efficiently, stably and with a longer life.

[0010] Preferably, the fixing mechanism includes a fixing socket, which is fixedly installed at the end of the air supply fan, and positioning blocks are fixedly connected on both sides of the fixing socket, and the bottom surfaces of the two positioning blocks are provided with fixing sockets. The fixing mechanism also includes a fixing screw, which is rotatably connected to the inner wall of the mounting seat, and the bottom end of the fixing screw is fixedly connected to a hexagonal head, and a U-shaped bracket is threadedly connected to the fixing screw, and the bottom end of the U-shaped bracket is slidably connected to a guide rod, and the guide rod is fixedly installed inside the mounting seat, which can facilitate the maintenance of the air supply fan.

[0011] The utility model provides a double-airbag balloon structure. Compared with the existing technology, it has the following advantages:

[0012] 1. The double-airbag balloon structure uses two air-supply blowers to inflate the first, second, third and fourth inner airbag parts. After the adjacent inner airbag parts are inflated, they support each other through the contact surfaces, forming a double-airbag structure with the outer airbag, and inflating the lower half of the outer airbag to prevent the lower half of the outer airbag from being deflated under force, thereby greatly reducing the resistance of the balloon, improving the stability of operation, and avoiding balloon damage and cable breakage.

[0013] 2. The double-airbag balloon structure is achieved by inserting the fixed socket and the positioning block into the inside of the mounting seat, and then using a wrench to rotate the hexagonal head. The rotation of the hexagonal head drives the fixed screw to rotate, and the rotation of the fixed screw drives the U-shaped bracket to move. The U-shaped bracket moves and is inserted into the fixed sockets on the two positioning blocks to fix the air supply fan, thereby facilitating the replacement and maintenance of the air supply fan and improving the convenience of maintenance.
