Description

Technical Field

[0001] The invention relates to the field of high-altitude wind energy power generation, and in particular to a device for preventing balloons from escaping. Background Art

[0002] High-altitude wind power generation technology has a history of more than 20 years. The new high-altitude wind power generation technology consists of three parts: aerial equipment, ground equipment and control system. The helium balloon is lifted to a certain height by carrying the working parachute group. The helium balloon is placed in the air to control the opening and closing of the parachute group to achieve the up and down circulation of the parachute group. The working parachute drives the ground friction reel, which drives the mechanical equipment through the pulling force, and then drags the generator on the ground to generate electricity, converting wind energy into mechanical energy, and then converting mechanical energy into electrical energy. In case of emergency, the helium in the helium balloon needs to be quickly released into the atmosphere. Generally, a sealed zipper and a knife are used to achieve rapid deflation in an emergency. The zipper about 80 cm long at the bottom of the helium balloon is manually opened to release the helium. Due to the poor sealing performance of the zipper and its short service life and easy damage, it is easy to cause abnormal leakage of helium and lead to economic losses. When the helium balloon needs to be released urgently after it is launched or when the helium balloon escapes, the ground cannot operate, which may cause the helium balloon to escape into the atmosphere and affect the route, airspace, aircraft and overhead equipment. Therefore, with regard to the above-mentioned method of releasing the helium in the balloon by combining a sealed zipper with a knife, due to the poor sealing performance of the zipper and its short service life and easy damage, it is easy to cause abnormal leakage of helium and lead to economic losses; and when the helium balloon needs to be released urgently after it is launched or when the helium balloon escapes, ground operations cannot be performed, which may cause the helium balloon to escape into the atmosphere and affect air routes, airspace, aircraft and overhead equipment, etc., a balloon escape prevention device can be designed to release the gas in the balloon through a remotely controlled escape valve to prevent the balloon escape from affecting air routes, airspace, aircraft, overhead equipment, etc. Summary of the invention

This solves the problem that the helium in the balloon is currently released by combining a sealed zipper with a knife. When the helium balloon needs to be released urgently after it is launched or when the helium balloon escapes, the ground cannot be operated, which easily leads to the problem of balloon escape.
