Description
Technical Field
[0001] The utility model relates to the technical field of aerostats, in particular to an aerostat. Background Art
[0002] Aerostats generally refer to aircraft that are lighter than air and rely on atmospheric buoyancy to rise into the air. In the fields of electronics and military and civilian use, hot air balloons are generally not included in the scope of aerostats. In addition, space airships do not necessarily rely on buoyancy. In addition to military use, large civilian aerostats can also be used for traffic, transportation, entertainment, disaster relief, film and television shooting, scientific experiments, etc. The existing patent, patent announcement number CN207274953U, discloses an aerostat, including: a capsule, with two through holes on the capsule; a bearing belt, with two ends of the bearing belt respectively penetrated into the capsule by two through holes and connected to the inner surface of the capsule, and the portion of the bearing belt outside the capsule forms a buckle structure. The utility model solves the problem of poor stability in the connection between the bearing belt and the capsule of the aerostat in the prior art.
[0003] With respect to the above-mentioned related technologies, the inventors believe that the following defects exist: in actual application, temperature changes during day and night will affect the net lift of the balloon, thereby causing changes in altitude. Moreover, when the airship is hanging in the mission cabin, the airship will cause it to shake during movement, which will affect its altitude under the action of gravity. If its altitude cannot be controlled, it will affect the efficiency of the use of the airship in actual application and will be inconvenient for subsequent operations. Therefore, we proposed an airship to solve the above-mentioned problems. Utility Model Content
[0004] In view of the deficiencies of the prior art, the utility model provides an aerostat, which solves the problem that it is inconvenient to control the height of the object, thus affecting the subsequent use.
[0005] To achieve the above objectives, the utility model is implemented through the following technical solutions: an airship, including an outer ball, thrusters are fixedly installed on both sides of the outer ball, an inner ball is fixedly installed inside the outer ball, a positioning plate is fixedly installed on the top of the outer ball, a turntable is arranged inside the positioning plate, a rotating rod is fixedly installed on the top of the turntable, and a wind turbine is fixedly installed on the top of the rotating rod.
[0006] One side of the outer ball is connected to an air outlet pipe, the surface of the air outlet pipe is connected to a valve, a vertical pipe is fixedly installed at the bottom of the outer ball, a piston is slidably connected inside the vertical pipe, a pull rod is fixedly installed at the bottom of the piston, and the bottom of the pull rod passes through the vertical pipe and extends to the outside of the vertical pipe.
[0007] Preferably, a ball is inlaid on the top of the rotating disk, and the surface of the ball is rollingly connected to the inner top wall of the positioning disk. A rotating hole for the rotating rod to pass through is opened on the top of the positioning disk.
[0008] Preferably, a buffer sheet is fixedly mounted on the inner wall of the positioning plate, one side of the buffer sheet contacts the surface of the turntable, and the bottom of the turntable contacts the inner bottom wall of the positioning plate.
[0009] Preferably, a sensor is fixedly mounted on the surface of the inner ball, and the sensor and the valve are electrically connected to an external controller.
[0010] Preferably, a pulling hole for the pulling rod to pass through is provided at the bottom of the vertical tube, and a positioning hole is provided on the pulling rod.
[0011] Preferably, a limiting rod is inserted into the piston, a limiting block is fixedly installed at the bottom of the limiting rod, a rod hole for the limiting rod to pass through is opened on the piston, and the inner wall of the rod hole is slidably connected to the surface of the limiting rod.
[0012] Preferably, a positioning spring is arranged around the surface of the limiting rod, the top of the positioning spring is fixedly connected to the inner top wall of the vertical tube, and the bottom of the positioning spring is fixedly connected to the top of the piston.
[0013] Beneficial Effects
[0014] The utility model provides an aerostat. Compared with the prior art, it has the following beneficial effects:
[0015] The aerostat consists of an inner sphere and an outer sphere through a double-layer balloon. The inner sphere is filled with helium and is completely closed, and the outer sphere is filled with air and connected to a valve. This design enables the device to exchange gas with the surrounding gas an unlimited number of times, ultimately achieving a change in the net lift of the device. When the altitude needs to be adjusted, the altitude adjustment can be completed by controlling the charging and discharging valve to pressurize air inward or outward. If the altitude needs to be increased, the valve releases air into the outer sphere. If the altitude needs to be lowered, the valve inhales air into the outer sphere, making it possible for the system to fly in a specified air layer.
[0016] At the same time, the power system of the thruster is composed of a high-speed brushless motor, blades and ducts. The thruster provides propulsion power for the system to help the system fly to the predetermined target. The thrusters should be installed at equal heights on both sides of the outer sphere. When the airship deviates from the coordinates of the predetermined location by a certain distance due to the influence of wind, the thruster starts to work, and changes the flight direction by changing the thrust of the thrusters on both sides to form a thrust difference, thereby pushing the device back to the target coordinate point. In fact, some small deviations are allowed, and it is not necessary to start propulsion work immediately as soon as the device deviates from the original coordinate point. This design can avoid frequent starting of the thruster and significantly extend its service life. BRIEF DESCRIPTION OF THE DRAWINGS
