Description

Technical Field

[0001] This invention relates to aviation meteorological early warning devices and belongs to the technical field of meteorological monitoring equipment. Background Technology

[0002] The low-altitude economy is an emerging economic model that primarily relies on low-altitude airspace (typically referring to airspace below 1000 meters vertically, but extending to within 3000 meters depending on regional characteristics and actual needs) for the flight activities of various manned and unmanned aircraft. This economic model encompasses a wide range of industries, from aircraft research and development and manufacturing, to the construction and operation of low-altitude flight infrastructure and flight service support. Before a low-altitude aircraft takes flight, several factors need to be considered, including meteorological factors such as wind speed, wind direction, temperature, humidity, and visibility, as well as the aircraft's performance, communication and navigation equipment, and emergency response measures.

[0003] A search revealed a Chinese patent with publication number CN218599265U that discloses an aviation meteorological sensor mounting structure. The key technical features are: a meteorological sensor body, a support shaft, a support, and a pole. The bottom of the meteorological sensor body is provided with three screw holes, and the bottom end of the support shaft is provided with a first combination screw and two second combination screws. The meteorological sensor body is fixedly connected to the outer wall of the support shaft by the first combination screw and the two second combination screws.

[0004] As shown in the above scheme, in related technologies, weather detection and early warning are accomplished by meteorological sensors installed on the ground. However, in cities or where the ground is obstructed, the measurement of data such as wind speed, wind direction, visibility, temperature and humidity will be inaccurate, making it difficult to provide timely early warnings.

[0005] Therefore, a new solution is needed to address this problem. Summary of the Invention

Four hooks extending horizontally are fixedly connected to the outer edge of the mounting plate, and each hook is fitted onto the take-up and release rope.

[0014] The present invention is further configured such that: the support member is provided in two sets and is respectively provided on the two side walls adjacent to the column; the support member includes a support plate hinged to the bottom end of the column, a telescopic rod with one end hinged to the end of the support plate away from the column and the other end connected to the column; a sliding plate is hinged to the end of the telescopic rod near the column; and the sliding plate is connected to the column by bolts.

[0015] The present invention is further configured such that there is an included angle of 20°-40° between the windward plate and the support shaft.

[0016] The beneficial effects of this invention are: 1. By setting up an airbag deployment and retraction device, an airbag, a flow stabilizer, and a multi-element meteorological sensor located on the airbag, hydrogen is filled into the airbag before the low-altitude aircraft takes off. The airbag is then released into the air through the airbag deployment and retraction device. The airbag drives the flow stabilizer and the multi-element meteorological sensor to measure meteorological elements in the air, thus avoiding the obstruction of ground buildings. When the multi-element meteorological sensor measures meteorological elements, the data collected by the multi-element meteorological sensor is processed and filtered by the first controller. The processed signal is sent to the second controller on the ground through a wireless signal generator and a wireless signal receiver. An alarm threshold is set in the second controller. When the value of a certain meteorological element or the combined value of multiple meteorological elements exceeds the alarm threshold, the second controller on the ground will trigger an audible and visual alarm to remind the staff that the weather conditions are not suitable for flight. 2. By installing temperature and pressure sensors inside the airbag, the temperature and pressure inside the airbag are measured when the airbag is too high. The data is then analyzed and processed by the first controller. A safety threshold is set in the first controller. When the temperature and pressure inside the airbag exceed the safety threshold, the airbag is depressurized through the electromagnetic pressure relief valve or the airbag's ascent altitude is reduced, thereby ensuring the safety of the airbag and the aerial equipment. 3. By installing a crosswind sensor on the flow stabilizer, when the airbag is at a high altitude and there is wind, the windward plate in the crosswind sensor on the windward side is rotated towards the center of the flow stabilizer due to the wind force, thereby driving the passive impeller to rotate to a state perpendicular to the flow stabilizer. At this time, the airflow is facing the passive impeller. The drive shaft connected to the passive impeller is connected to the connecting shaft through a magnetic block. Driven by the passive impeller, the active impeller rotates accordingly, thereby applying an upward thrust to the flow stabilizer to counteract the lateral force exerted by the crosswind on the airbag. This makes it less likely for the airbag to move too much at high altitudes and less likely to expand or become entangled with other obstacles. 4. By wrapping a protective umbrella around the airbag, in an emergency, if the airbag explodes, the protective umbrella will instantly expand under the airflow generated by the explosion, which can effectively reduce the descent speed of the flow stabilizer and protect the safety of the equipment. 5. By setting up an airbag deployment and take-up device, when the airbag needs to be launched, the deploy motor is started, which drives the take-up shaft and reciprocating screw in the four sets of deployment and take-up mechanisms to rotate simultaneously through the transmission of worm gear and worm, thereby gradually releasing the deployment and take-up rope. With the cooperation of the four deployment and take-up ropes, the flow stabilizer can always be kept in a horizontal state, making the data collection of the multi-element meteorological sensor more accurate. When the airbag needs to be retracted, the deploy motor is rotated in the opposite direction, so that the deployment and take-up rope is gradually retracted and can be evenly wound on the take-up shaft.

[0027] To facilitate a clear understanding of the technical means, creative features, objectives, and effects of this invention, the invention will be further described below in conjunction with specific illustrations.

[0028] like Figures 1-9 As shown, the aviation meteorological warning device includes an airbag 1 and an airbag 1 deployment and deployment device installed on the ground. The bottom of the airbag 1 is connected to a horizontally positioned flow stabilizer 4 via a first connecting rope 3. Below the flow stabilizer 4 is a mounting plate 5, on which multi-element meteorological sensors 6 are fixedly mounted. Several extension rods 7 are fixedly connected to the outer edge of the mounting plate 5, extending upwards and at an angle away from the center of the flow stabilizer 4, and are fixedly connected to the bottom surface of the flow stabilizer 4.

[0029] To facilitate the processing and transmission of data collected by the multi-element meteorological sensor 6, a first controller 8 and a wireless signal generator 9 are also fixedly mounted on the mounting plate 5. The airbag 1 deployment and retraction device is equipped with a wireless signal receiver 10, a second controller 11, and an alarm 12. The multi-element meteorological sensor 6 and the wireless signal generator 9 are both electrically connected to the first controller 8, and the wireless signal receiver 10 and the alarm 12 are both electrically connected to the second controller 11.

[0030] To further ensure the safety of the airbag, the airbag 1 includes a body 13 and an air nozzle 14. The body 13 is equipped with a temperature sensor 15 and a pressure sensor 16. The air nozzle 14 is equipped with an electromagnetic pressure relief valve 17. The temperature sensor 15, the pressure sensor 16 and the electromagnetic pressure relief valve 17 are electrically connected to the first controller 8.

[0031] By installing a temperature sensor 15 and a pressure sensor 16 inside the airbag 1, the temperature and pressure inside the airbag 1 are measured when the airbag 1 is too high. The measured temperature and pressure are analyzed and processed by the first controller 8. A safety threshold is set in the first controller 8. When the temperature and pressure inside the airbag 1 exceed the safety threshold, the airbag 1 is depressurized by the electromagnetic pressure relief valve 17 or the airbag 1 is lowered, thereby ensuring the safety of the airbag 1 and the air equipment.

[0032] Several second thin wires 18 are fixedly connected to the air nozzle 14. A protective umbrella 19 is provided over the upper part of the airbag 1, and the second thin wires 18 are fixedly connected to the outer edge of the protective umbrella 19. By wrapping the protective umbrella 19 around the airbag 1, in an emergency, if the airbag 1 explodes, the protective umbrella will instantly expand under the airflow generated by the explosion of the airbag 1, which can effectively reduce the descent speed of the flow stabilizer 4 and protect the safety of the equipment.

[0033] The airbag 1 retraction and deployment device includes a column 20, a support member 21 disposed on the side wall of the column 20, a storage box 22 fixedly installed on the top of the column 20 with an open top, and four sets of retraction and deployment mechanisms 23 disposed in the storage box 22.

[0034] The support member 21 has two sets and is respectively set on the two side walls adjacent to the column 20. The support member 21 includes a support plate 24 hinged to the bottom end of the column 20 and a telescopic rod 25 with one end hinged to the end of the support plate 24 away from the column 20 and the other end connected to the column 20. The telescopic rod 25 is preferably configured to be an adjustable telescopic rod 25 with bolts. A sliding plate 26 is hinged to the end of the telescopic rod 25 near the column 20. The sliding plate 26 is connected to the column 20 by bolts.

[0035] The winding and unwinding mechanism 23 includes a storage box 27 fixedly connected to the side wall of the storage box 22, a winding shaft 28 rotatably connected inside the storage box 27 and vertically arranged, a winding and unwinding rope 29 wound around the winding shaft 28, ear plates 30 fixedly connected to the upper and lower ends of the outer wall of the storage box 27, a reciprocating screw 31 rotatably connected between the ear plates 30 and parallel to the winding shaft 28, a moving block 32 connected to the reciprocating screw 31, a first gear 33 fixedly connected to the bottom end of the winding shaft 28, and a second gear 34 fixedly connected to the bottom end of the reciprocating screw 31 and meshing with the first gear 33. The moving block 32 has a guide hole 35 for the winding and unwinding rope 29 to pass through. The side wall of the storage box 27 has a groove 36 extending in the vertical direction. The winding and unwinding rope 29 passes through the groove 36 and the guide hole 35 in sequence and is fixedly connected to the bottom surface of the flow stabilizer plate 4.

[0036] The bottom surface of the storage box 22 is rotatably connected to a drive gear 37 that meshes with four second gears 34 respectively. The top of the drive gear 37 is coaxially fixedly connected to a worm gear 38. Inside the storage box 22, a worm 39 is provided through a shaft seat that meshes with the worm gear 38. One end of the worm 39 is connected to a receiver / discharger 40, which is electrically connected to the second controller 11.

[0037] Four first connecting ropes 3 are provided. The tops of the four first connecting ropes 3 are twisted together and fixedly connected to the air nozzle 14. The connection points between the four take-up and release ropes 29 and the flow stabilizer 4, and the connection points between the four first connecting ropes 3 and the flow stabilizer 4, are staggered in the circumferential direction. In order to reduce the possibility of the flow stabilizer 4 twisting and affecting the data collection of the multi-element meteorological sensor 6, four hooks 41 extending in the horizontal direction are fixedly connected to the outer edge of the mounting plate 5. The hooks 41 are fitted one-to-one with the take-up and release ropes 29.

[0038] When airbag 1 needs to be launched, the take-up and release motor 40 is started, which drives the take-up shaft 28 and reciprocating screw 31 in the four sets of take-up and release mechanisms 23 to rotate simultaneously through the transmission of worm gear 38 and worm 39. This gradually releases the take-up and release rope 29, and with the cooperation of the four take-up and release ropes 29, the flow stabilizer 4 can always be kept in a horizontal state, so that the multi-element meteorological sensor 6 can collect data more accurately. When airbag 1 needs to be retracted, the take-up and release motor 40 is rotated in the opposite direction, so that the take-up and release rope 29 is gradually retracted and can be evenly wound on the take-up shaft 28.

[0039] To ensure the stability of the airborne equipment, four sets of crosswind sensors 42 are evenly distributed around the outer edge of the flow stabilizer plate 4. The crosswind sensor 42 includes a through groove 43 opened on the edge of the flow stabilizer plate 4, a support ring 44 set in the through groove 43, a fixed sleeve 45 set at the center of the support ring 44, several fixed rods 46 fixedly connected between the support ring 44 and the fixed sleeve 45, a drive shaft 47 rotatably connected in the fixed sleeve 45, and a passive impeller 48 fixedly connected to the drive shaft 47. The support ring 44 is perpendicular to the flow stabilizer plate 4.

[0040] A vertically penetrating mounting groove 49 is provided at the center of the flow stabilizer plate 4. A rotating ring 50 is rotatably connected in the mounting groove 49. An active impeller 51 is fixedly connected in the rotating ring 50. The rotation axis of the active impeller 51 is vertically arranged. The drive shaft 47 and the active impeller 51 are connected by a transmission component 52. The drive shaft 47 is perpendicular to the rotation axis of the active impeller 51, and the extension line of the drive shaft 47 and the rotation axis of the active impeller 51 are located in the same plane.

[0041] Supporting ring 44 is fixedly connected to two sides of support shaft 53. Supporting ring 44 is rotatably connected to the inner wall of through groove 43 through support shaft 53. Support shaft 53 is perpendicular to the rotation axis of drive shaft 47 and drive impeller 51. When support ring 44 is parallel to flow stabilizer plate 4, fixed sleeve 45 is located above support ring 44, and windward plate 54 is provided on the outer wall of fixed sleeve 45. One side of windward plate 54 faces away from drive impeller 51. There is an angle of 20°-40° between windward plate 54 and support shaft 53.

[0042] A reset torsion spring 55 is provided between the support shaft 53 and the inner wall of the through groove 43. The reset torsion spring 55 has an elastic tendency to flip the support ring 44 to be parallel to the flow stabilizer plate 4. A limit block 56 is fixedly connected to the top of the inner wall of the through groove 43 near the active impeller 51. When the support ring 44 rotates to be parallel to the flow stabilizer plate 4, the top surface of the support ring 44 abuts against the limit block 56.

[0043] The transmission component 52 includes a through hole 57 formed inside the flow stabilizer plate 4 and connected at both ends to the through groove 43 and the mounting groove 49 respectively; a connecting shaft 58 rotatably connected in the through hole 57; an insertion groove 59 formed at the end of the transmission shaft 47 away from the passive impeller 48; a telescopic shaft 60 slidably inserted in the insertion groove 59 and connected to the insertion groove 59 by a spline; a tension spring 61 set between the end of the insertion groove 59 and the telescopic shaft 60; a plurality of magnetic blocks 62 set at the end of the telescopic shaft 60 near the connecting shaft 58; and a plurality of corresponding magnetic blocks 62 formed on the end face of the connecting shaft 58 near the end face of the telescopic shaft 60. The magnetic blocks 62 are hemispherical, and the plurality of magnetic blocks 62 are circumferentially fixed to the outer edge of the telescopic shaft 60. The end of the connecting shaft 58 near the telescopic shaft 60 is made of magnetic material.

[0044] The bottom surface of the rotating ring 50 is provided with an end face ratchet 64 around its circumference. One end of the connecting shaft 58 extending to the mounting groove 49 is fixedly connected to an elastic ratchet 65. The elastic ratchet 65 includes a wheel body 66 and a plurality of ratchet teeth 67 fixedly connected to the circumferential wall of the wheel body 66 and evenly distributed around its circumference. The elastic ratchet 65 drives the rotating ring 50 to rotate, causing the active impeller 51 to drive the airflow to move upward.

[0045] By installing a crosswind sensor 42 on the flow stabilizer 4, when the airbag 1 is at a high altitude and there is wind, the windward plate 54 in the crosswind sensor 42 located on the windward side is subjected to the wind force and rotates towards the center of the flow stabilizer 4, thereby driving the passive impeller 48 to rotate to a state perpendicular to the flow stabilizer 4. At this time, the airflow is facing the passive impeller 48. The drive shaft 47 connected to the passive impeller 48 is connected to the connecting shaft 58 through the magnetic block 62. Under the drive of the passive impeller 48, the active impeller 51 rotates accordingly, thereby applying an upward thrust to the flow stabilizer 4 to counteract the lateral force exerted by the crosswind on the airbag 1, so that the airbag 1 is less likely to move too much at high altitudes and is less likely to expand or become entangled with other obstacles.

[0046] The implementation principle of this invention is as follows: By setting up an airbag 1 deployment and retraction device, airbag 1, flow stabilizer 4, and multi-element meteorological sensor 6 located on airbag 1, hydrogen is filled into airbag 1 before the low-altitude aircraft takes off. Airbag 1 is then released into the air through the airbag 1 deployment and retraction device. Airbag 1 drives flow stabilizer 4 and multi-element meteorological sensor 6 to measure meteorological elements in the air, thus avoiding obstruction by ground buildings. When the multi-element meteorological sensor 6 measures meteorological elements, the data collected by the multi-element meteorological sensor 6 is processed and filtered by the first controller 8. The processed signal is sent to the second controller 11 on the ground through the wireless signal generator 9 and the wireless signal receiver 10. The second controller 11 sets an alarm threshold. When the value of a certain meteorological element or the combined value of multiple meteorological elements exceeds the alarm threshold, the second controller 11 on the ground will trigger the alarm 12 to issue an audible and visual alarm, reminding the staff that the weather conditions are not suitable for flight.
