Description

Technical Field

[0001] The present invention relates to the technical field of meteorological observation, and in particular to a meteorological unmanned aerial vehicle and an observation system. Background Art

[0002] With the development of science and technology and the progress of society, drones are increasingly being used in various fields. For example, drones are used in the field of meteorology. They are generally equipped with meteorological sensors (temperature, humidity, air pressure, wind direction, wind speed sensors), visible light cameras, infrared cameras, sampling mechanisms, etc., which can facilitate meteorological detection in the required airspace and air testing, take photos of the ground, etc., which greatly promotes the development of meteorological work. Among them, atmospheric sampling is a common method for observing and analyzing the meteorological environment. The existing drone observation system, when sampling the atmosphere, mainly samples the atmosphere through an atmospheric sampler, collects the collected samples into a sampling bottle, and waits until the drone returns to analyze the atmospheric samples in detail to achieve the purpose of observing the weather.

[0003] In the prior art, a meteorological drone observation system with publication number CN117740480A pushes a sealing ball to move until the sealing ball is separated from the mouth of the sampling bottle, and then starts the exhaust assembly to open the sampling bottle with the sealing ball pushed open, so that the sampling bottle is in a ventilated state, and then delivers gas to the inside of the sampling bottle through an air pump. After waiting for the gas to completely fill the sampling bottle, the second electric cylinder is closed to separate the sealing ball. The sealing ball is pushed back to the mouth of the sampling bottle under the elastic force of the first spring, and the exhaust assembly is closed at the same time to prevent the air collected in the sampling bottle from flowing out, thereby completing the atmospheric sampling at this position, and then driving the drone body to fly to the next position, repeating the sampling steps, and sampling the atmosphere at multiple positions can be achieved, thereby improving the efficiency of detection.

[0004] Although the above-mentioned device can sample and observe the atmosphere at multiple locations, there are still some defects in the actual observation process.

[0031] In order to more clearly understand the above-mentioned objects, features and advantages of the present invention, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0032] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0033] like Figure 1-11 A meteorological drone shown in the figure comprises a drone body 1, and an observation box 2 fixedly connected to the drone body 1, a partition 3 fixedly connected to the inner side of the observation box 2, a fan 4 fixedly connected to the bottom end of the observation box 2, an air inlet end of the fan 4 is arranged through the front side of the observation box 2, an air outlet end of the fan 4 is fixedly connected to an L-shaped tube 5 and is arranged through the top end of the partition 3, an air inlet pipe 6 is fixedly connected to the top end of the L-shaped tube 5, a top plate 7 is clamped on the top end of the observation box 2, three groups of support seats 8 are fixedly connected to the top end of the partition 3 at equal distances, a sampling cylinder 9 can be supported by the support seats 8, and four are arranged in each group, a sampling cylinder 9 is arranged above the support seats 8, an upper cylinder 10 is fixedly connected to the top of the sampling cylinder 9, four lower cylinders 11 are fixedly connected to the top end of the air inlet pipe 6 at equal distances, air inlet holes are opened at the top ends of the upper cylinder 10 and the lower cylinder 11, and a blocking mechanism for blocking the air inlet holes is arranged inside the upper cylinder 10 and the lower cylinder 11;

[0034] A straight tube 12 is provided at the bottom of the top plate 7 and at a position corresponding to the lower cylinder 11. A conduit 13 is fixedly connected to the bottom of the straight tube 12 and at a position corresponding to the upper cylinder 10 and the lower cylinder 11. An upper electric air valve 14 is provided on the conduit 13 corresponding to the upper cylinder 10. Through the setting of the upper electric air valve 14, it is convenient to sample the atmosphere of the same area multiple times in sequence. At the same time, the drone body 1 can be controlled to move, change the sampling position, sample different positions in the same area, and improve the accuracy of observation. A lower electric air valve 15 is fixedly connected to the side wall of the air inlet pipe 6. Through the lower electric air valve 15 The arrangement is convenient for exchanging the gases in the L-shaped tube 5, the air inlet pipe 6 and the straight tube 12 before sampling, so as to collect the sampled atmosphere in the area in the sampling bag 29. The top of the straight tube 12 is fixedly connected with a T-shaped block 16 and is arranged through the top of the top plate 7. The top plate 7 is provided with an extrusion block 17, and both sides of the extrusion block 17 are inclined. It should be noted that the extrusion block 17 is inclined so that when the extrusion block 17 is moved to the other side of the top plate 7, it will not be reset, and it can be operated during subsequent sampling. The top plate 7 is provided with a moving mechanism for driving the extrusion block 17 to move;

[0035] The top of the T-block 16 is set as a smooth arc surface, which is convenient for the inclined surface of the extrusion block 17 to squeeze the T-block 16 more smoothly and slide downward. A pair of upper springs 22 are fixedly connected between the inner side of the T-block 16 and the top of the top plate 7. Through the setting of the upper springs 22, when the T-block 16 loses the extrusion of the extrusion block 17, the T-block 16 is quickly pushed to slide upward for reset. The bottom of the conduit 13 is fixedly connected with a conical sealing ring 23. Through the setting of the conical sealing ring 23, it is not only convenient to push the spherical rubber block 28 downward, but also can be closely fitted with the inner wall of the air inlet, so as to improve the sealing performance in the subsequent sampling process. The outer wall of the conical sealing ring 23 is equidistantly provided with four upper air holes 24. Through the setting of the upper air holes 24, it is avoided that the bottom of the conical sealing ring 23 is blocked by the spherical rubber block 28, so that the sampled gas cannot be discharged into the sampling bag 29.

[0036] The moving mechanism includes a driving motor 18, a pair of fixed plates 19 are fixedly connected to the top of the top plate 7, a threaded rod 20 is rotatably connected between the fixed plates 19, the driving motor 18 is fixedly connected to the side wall of one of the fixed plates 19, the output end of the driving motor 18 passes through the fixed plate 19 and is fixedly connected to the side wall of the threaded rod 20, a driving block 21 is threadedly connected through the threaded rod 20, and the extrusion block 17 is fixedly connected to the side wall of the driving block 21;

[0037] When using the meteorological drone for sampling, firstly, the drone body 1 is controlled to fly to the specified sampling position and height through the main remote controller, and then the drone is controlled to hover, and the driving motor 18 of the mobile mechanism is controlled to start and drive the threaded rod 20 to rotate, thereby driving the threaded driving block 21 to move, and at the same time driving the extrusion block 17 to slide, and then the smooth arc surface of the top of the T-block 16 is squeezed by the inclined surface of the extrusion block 17 to slide downward, and the upper spring 22 is gradually compressed, thereby driving the corresponding straight tube 12 and the conduit 13 to slide downward, and then when the top of the T-block 16 slides out from the inclined surface of the extrusion block 17 and slides to the bottom of the extrusion block 17, the conical sealing ring 23 at the bottom of the conduit 13 will be completely inserted into the air inlet holes on the upper cylinder 10 and the lower cylinder 11. In this process, the conical sealing ring 23 slides downward, and the spherical rubber block 28 in the air inlet hole is squeezed downward to slide downward, and the lower spring 25 is gradually compressed, thereby opening the air inlet, and the driving block 21 will touch the corresponding travel switch 37;

[0038] Then the travel switch 37 transmits the signal to the controller, the controller controls the driving motor 18 to stop running, and controls the fan 4 to start to draw in the sampled gas, which then enters the air intake pipe 6 through the L-shaped tube 5, and in this process, the controller transmits the signal to the timing controller 36, at which time the timing controller 36 controls the lower electric valve 15 to open, and then under the action of the gas drawn in by the fan 4, the gas in the air intake pipe 6 and the straight tube 12 is exchanged with the gas in the sampling area, and then after the exchange time is reached, the timing controller 36 controls the lower electric valve 15 to close through the setting program, and opens the three upper electric valves 14 in sequence, so that the gas drawn in through the fan 4 is discharged into the three sampling bags 29 in sequence under the transmission of the L-shaped tube 5, the air intake pipe 6, the straight tube 12, the conduit 13, the conical sealing ring 23 and the upper air hole 24, so as to realize multiple sampling of the area, and in the process of opening the upper electric valve 14, the drone body 1 can be controlled to move to a different position, and the area can be sampled multiple times at different positions;

[0039] Finally, after the sampling of the area is completed, the driving motor 18 can be controlled by the main remote control to continue to start, drive the driving block 21 to move, remove the extrusion block 17 from the T-block 16, and move it to the next T-block 16. At the same time, the above operation will be repeated in reverse to reset, and then the drone body 1 will be controlled to fly to the next sampling position, and the above operation will be repeated repeatedly to perform sampling.

[0040] In order to improve the stability of the device during operation, a guide rod 34 is fixedly connected between the fixed plates 19. The setting of the guide rod 34 can play a guiding role when the threaded rod 20 rotates to drive the driving block 21 to move, thereby preventing the driving block 21 from rotating with the threaded rod 20, thereby improving the stability of the device during operation. The guide rod 34 passes through the inner wall of the driving block 21, and a pair of handles 35 are fixedly connected to the top of the top plate 7. The setting of the handles 35 makes it easy for observers to remove the unstuck top plate 7, thereby opening the observation box 2 to take and place the sampling tube 9, thereby improving the convenience of the device.

[0041] In order to avoid gas leakage after sampling, the blocking mechanism includes a lower spring 25, a lower plate 26 is fixedly connected to the inner side of the upper cylinder 10 and the lower cylinder 11, and a plurality of exhaust holes 27 are equidistantly provided at the top of the lower plate 26. The setting of the exhaust holes 27 facilitates the normal discharge of the sampled atmosphere. A plurality of lower springs 25 are provided, and the plurality of lower springs 25 are fixedly connected to the top of the lower plate 26. A spherical rubber block 28 for blocking the air inlet hole is fixedly connected to the top of the lower spring 25.

[0042] The spherical rubber block 28 is pushed upward to slide under the elastic force of the lower spring 25, thereby blocking the air inlet. Then, during the sampling process, the conical sealing ring 23 will move downward and insert into the air inlet, and push the spherical rubber block 28 downward, while compressing the lower spring 25, thereby opening the air inlet, and then the atmosphere in the area can be sampled.

[0043] In order to ensure normal sampling of the device, a sampling bag 29 is fixedly connected to the bottom of the lower cylinder 11. The setting of the sampling bag 29 can keep the sampling bag 29 in a gas-free state, which not only avoids the gas in the sampling bag 29 from affecting the accuracy of subsequent observations, but also avoids the problem that the original gas in the sampling device cannot be discharged during the sampling process. A pair of air outlet holes 30 are opened on the top of the sampling tube 9. At the same time, through the setting of the air outlet holes 30, the gas in the sampling tube 9 can be discharged when the sampling bag 29 expands.

[0044] In order to be able to adjust the number of sampling tubes 9 carried according to observation requirements, one end of the sampling tube 9 is fixedly connected to a threaded block 31, and the other end of the sampling tube 9 is provided with an upper threaded groove 32 adapted to the threaded block 31, and the inner side of the observation box 2 and the corresponding position of the sampling tube 9 are provided with a lower threaded groove 33 adapted to the threaded block 31. During installation, the sampling tube 9 is screwed into the corresponding lower threaded groove 33 through the threaded block 31, and then other sampling tubes 9 are threadedly installed in the upper threaded groove 32 through the threaded block 31 in turn, thereby realizing the installation of each group of sampling tubes 9;

[0045] When the sampling area is reduced, the sampling tube 9 can be rotated to rotate the threaded block 31 from the upper threaded groove 32 to take out the sampling tube 9. Therefore, the number of sampling tubes 9 can be adjusted according to the number of sampling positions, thereby reducing the overall weight of the meteorological UAV, increasing the endurance energy of the meteorological UAV, and being able to be flexibly adjusted according to actual usage needs without hindering the normal operation of the observation system.

[0046] A meteorological drone observation system includes a timing controller 36, which is fixedly connected to the inner side of the observation box 2, a mobile mechanism is electrically connected to the main remote controller of the drone body 1, and a travel switch 37 is fixedly connected to the top of the top plate 7 and the position corresponding to the upper cylinder 10. The travel switch 37 is electrically connected to the mobile mechanism, the fan 4 and the timing controller 36 through the controller. When the mobile mechanism is started by the main remote controller, the driving block 21 is driven to move, so that the conical sealing ring 23 is driven to be fully inserted into the upper cylinder 10 and the lower cylinder 11, and the driving block 21 touches the corresponding travel switch 37 (here it is required to It should be noted that each travel switch 37 is electrically connected to the corresponding upper electric air valve 14 through the controller (not all the upper electric air valves 14 are opened every time), thereby transmitting a signal to the controller, the controller controls the drive motor 18 to turn off, and controls the fan 4 to start, and transmits a signal to the timing controller 36, the timing controller 36 controls the lower electric air valve 15 and the upper electric air valve 14 to switch in turn, so as to realize automatic ventilation and sampling of the device, the timing controller 36 controls the lower electric air valve 15 and each group of three upper electric air valves 14 to open in turn, so that the group of sampling channels can sample the atmosphere of the same area multiple times;

[0047] Through the setting of the observation system, not only can the gas sampled last time in the air intake pipe 6, the L-shaped pipe 5 and the straight pipe 12 be automatically discharged, but the lower electric air valve 15 and the upper electric air valve 14 can also be individually controlled by the main remote controller of the drone body 1. When it is necessary to provide observation sampling accuracy, after sampling in each sampling bag 29 is completed, the lower electric air valve 15 can be controlled to open for gas exchange, thereby improving the observation accuracy of the device.

[0049] Those skilled in the art should understand that the present invention is not limited to the above-mentioned embodiments. The above-mentioned embodiments and the specification only describe the principles of the present invention. Various changes and improvements may be made to the present invention without departing from the spirit and scope of the present invention.
