Description

TECHNICAL FIELD

[0001] The present disclosure relates to the technical field of aerostats, and more particularly, to an emergency exhaust device of an aerostat and an aerostat with the emergency exhaust device. BACKGROUND

[0002] An aerostat generally refers to a soft-structure aircraft with a specific gravity lighter than air and capable of ascending by atmospheric buoyancy. The aerostat is composed of a gasbag made of a high polymer composite material and various devices and payloads arranged on the bag body of the gasbag. The bag body is filled with a lifting gas with a density smaller than air. The density difference between the gas inside and outside the bag body provides buoyancy for the aerostat, thereby completing the ascension of the aerostat. Aerostats generally include balloons and airships. The aerostat ascends from the ground and stays in the upper air at a certain height for regional cruising and scientific experiments. According to different aerostat types and test requirements, the aerostat stays in the upper air at a height of 0-30 km, generally in the troposphere or the stratosphere. At this height, many other aircrafts are also operating in the upper air. If the aerostat loses control accidentally, it needs to be handled urgently to make it fall quickly to avoid interference with and threat to the flight safety of other aircrafts. Therefore, the aerostat itself must be equipped with an emergency response handling device to quickly exhaust the lifting gas in the bag body when the aerostat loses control or has an accident, so as to make the aerostat fall quickly and always be controllable, thereby minimizing the risk.

[0003] At present, the emergency response handling device includes large-diameter or a large number of exhaust valves arranged on the bag body. In an emergency, the valves are opened to exhaust the lifting gas in the bag body. However, the exhaust area of the exhaust valves is small and the exhaust speed is slow, which cannot achieve the purpose of making the aerostat fall quickly. Moreover, since the aerostat stays in the troposphere or the stratosphere, the environmental temperature and atmospheric pressure in this region are low, and the solar radiation is strong. Long-term low temperature and low pressure will affect the electronic components in the exhaust valves, and the lubrication of the transmission mechanism in the exhaust valves will also be affected. The exhaust valves have the risk of gas leakage and cannot play a safe control role in an emergency. SUMMARY

[0004] To solve at least one of the technical problems in the prior art, the embodiments of the present disclosure provide an emergency exhaust device of an aerostat and an aerostat with the emergency exhaust device, which can expand the exhaust area, improve the exhaust speed, and realize the quick landing of the aerostat.

[0036] Hereinafter, embodiments of the present disclosure will be described with reference to the accompanying drawings. It should be understood, however, that the description which follows is merely illustrative and is not intended to limit the scope of the present disclosure. In the following detailed description of embodiments of the present disclosure, numerous specific details are set forth in order to provide a thorough understanding of the present disclosure.

[0039] In the event that a statement similar to "at least one of A, B, and C, etc." is used, it is generally intended that the use of "or" in this context is inclusive - i.e. the inclusion of a or b or c means any of the A, B, or C options are permissible under the present application, and multiple options are to be considered within the scope of embodiments of the present application.

In addition, statements regarding "at least one of A, B or C" statement are predicated on the same open-ended terms as those above regarding the use of "or" in the context of the at least one of A, B, and C.

[0040] Figure 1 is a side view of a conventional emergency response handling device.

[0041] The conventional emergency response handling device is an exhaust valve, as shown in Figure 1 The exhaust valve includes a valve body 100, a valve cover 200, an electric control unit 300, and a pull rod 400. The exhaust valve is driven by the electric control unit 300 to open and close the valve. When an emergency occurs, the electric control unit 300 receives an emergency handling signal, and the electric control unit 300 drives the pull rod 400 to act. The pull rod 400 and the valve cover 200 are fixedly connected, and under the action of the driving force, the valve cover 200 moves away from the valve body 100, the exhaust valve is opened, the lift gas is discharged, and the airship is lowered.

[0042] However, there are mainly two problems in using this exhaust valve. On the one hand, the exhaust area of the exhaust valve is small and the weight of the exhaust valve is large. Since the exhaust valve contains many electric units and metal structures, the valve body, transmission mechanism, sealing mechanism, supporting mechanism, opening and closing mechanism, etc. are all metal components, which are similar in structure and principle to industrial electric valves. An exhaust valve with a weight of about 8 kg has an exhaust area of only 300 cm 2On the other hand, the exhaust valve has poor reliability and has the risk of leakage. Since the aerostat stays in the troposphere or the stratosphere, the area has low environmental temperature, low atmospheric pressure and strong solar radiation. Long time of low temperature and low pressure will affect the electronic components in the exhaust valve, the lubrication of the transmission mechanism will also be affected, the rubber material will age and become brittle, the overall sealing performance will be greatly reduced, the exhaust valve will be exposed to the air for a long time and will encounter rain and snow weather. Once icing or action jam occurs, the reliability of the exhaust valve cannot be guaranteed. The exhaust valve is sealed by rubber and other materials. In the harsh weather environment, the exhaust valve cannot be opened and cannot play a role in safety control and emergency.

[0043] To solve the problems of small exhaust area, slow exhaust speed and exhaust valve leakage, according to the inventive concept of one aspect of the present disclosure, an initiator is installed on the top surface of the capsule of the aerostat, the capsule is filled with lifting gas, a cutting rope is connected with the initiator, the inside of the cutting rope is filled with combustible material to be ignited after the initiator is detonated, and the cutting rope cuts the capsule under the action of the blasting force, so that the lifting gas is discharged from the inside of the capsule, the exhaust area is expanded, the exhaust speed is improved, and the aerostat can land quickly.

[0061] According to the embodiment of the present disclosure, the support surface A can also be selected at a position close to the highest point of the top of the capsule 6.

[0062] According to the embodiment of the present disclosure, the length of the cutting rope 4 is determined based on the discharge area of the lifting gas and the flight height of the aerostat.
