Description

Technical Field

[0001] The utility model relates to the field of ship exhaust gas monitoring components for unmanned aerial vehicles, and specifically relates to a ship exhaust gas monitoring component for unmanned aerial vehicles. Background Art

[0002] Ship exhaust gas detection refers to the monitoring of the exhaust gas emitted by ships to evaluate its impact on the environment and ensure compliance with relevant emission standards. Accurate detection can effectively control ship exhaust gas emissions and reduce harm to the environment and human health.

[0003] At present, ship exhaust gas detection methods generally include two categories: real-time rapid detection and sampling detection. In terms of real-time detection, it includes the use of high-performance sensors, which are based on advanced electrochemical principles, have high sensitivity and low detection limits, and can accurately capture the concentration of harmful gases in ship exhaust gas. There is also a continuous ship exhaust gas emission monitoring system specially designed and installed on the hull.

[0004] Sampling detection is still the most accurate detection method. When it is necessary to retain the exhaust gas sample, generally, a gas sampling device is placed at a certain distance from the air outlet by manual or mechanical means for collection and preservation.

[0005] However, the current sampling detection generally requires the cooperation of the other ship to stop the ship, and relevant personnel board the ship to operate the equipment for sampling. The sampling efficiency is low, and sampling requires the other ship to stop, which seriously affects the operation of the other ship in non-annual inspection situations. Therefore, this sampling method generally needs to master the evidence of the excessive exhaust gas emissions of the other party before it can be implemented. Summary of the Utility Model

[0006] Based on this, the purpose of the utility model is to provide a ship exhaust gas monitoring component for unmanned aerial vehicles to solve the technical problems of low efficiency of current ship exhaust gas collection and difficulty in collecting exhaust gas from passing ships in operation.

An air inlet cover is provided on one side of the gas storage cylinder gear ring. An air inlet that cooperates with the air guide holes is formed on the air inlet cover.

[0010] By adopting the above technical solution, the provided spring cylinder fixes the spring. The top plate cooperates with the spring to extract or extrude gas. The gas storage cylinder gear ring drives the air inlet cover to rotate, and then drives the air inlet to align with the air guide holes, thereby realizing air intake and exhaust.

[0011] The present utility model is further configured such that a polytetrafluoroethylene ring that cooperates with the air guide cylinder is provided inside the outer shell.

[0012] By adopting the above technical solution, the provided polytetrafluoroethylene ring plays a role in lubrication and fixation, enabling the air guide cylinder to rotate inside the outer shell.

[0029] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present utility model and should not be construed as limiting the present utility model.

[0030] Next, the embodiments of the present utility model will be described according to its overall structure.

[0031] Embodiment 1

[0032] A ship exhaust monitoring component for an unmanned aerial vehicle comprises a shell 1, wherein a plurality of groups of air storage components are arranged inside the shell 1, a motor 7 is arranged inside the shell 1, a gear 4 is arranged at the output end of the motor 7, an air guide tube 9 is rotatably connected in the middle of the shell 1, an air guide tube gear ring 12 cooperating with the gear 4 is arranged on the outside of the air guide tube 9, a tooth plate 11 cooperating with the air storage component is arranged on the outside of the air guide tube 9, the air guide tube 9 is provided with an air outlet 16, and a plurality of groups of air guide holes 10 cooperating with the air outlet 16 and the air storage component are arranged inside the shell 1.

[0033] A fixing is provided on the top of the housing, and a buckle or slot is used for connection according to the standard of the drone. Before connection, the motor 7 is connected to the circuit of the drone, or a separate additional lithium battery pack can be used. After connection, the motor 7 is connected to the compatible control port of the drone circuit, or the motor 7 is connected to the drone signal first sending module by means of an additional control circuit. If necessary, a separate additional control circuit and signal transceiver module can be used.

[0034] In this embodiment, after the connection, the motor 7 can be controlled to rotate, and then the air guide tube 9 is driven to rotate under the action of the gear 4 and the air guide tube ring gear 12, thereby driving the tooth plate 11 to rotate, and the air guide tube 9 and the tooth plate 11 are rotated to a limit and then rotated in the opposite direction to the limit, and most of the gas inside the air storage cylinder 3 is discharged.

[0035] When the tooth plate 11 rotates, it passes through the gas cylinder gear ring 5 and meshes with it, thereby driving the gas cylinder gear ring 5 and the air inlet cover 6 to rotate. When the air inlet 17 and the air outlet 16 are connected through the air guide hole 10, the gas inside the gas cylinder 3 is discharged under the action of the spring 14 and the top plate 15, and enters a ready-to-use state.

[0036] After the connection is completed, the drone carrying the components flies to the chimney exhaust port of the ship to be inspected. After arriving above the exhaust port of the target, the drone is controlled to keep flying in the exhaust gas, and the motor 7 is controlled to rotate so that the air inlet 17 and the air outlet 16 are connected through the air guide hole 10. At this time, the exhaust gas enters the air storage cylinder 3 under the action of the air guide groove 18 with the wind pressure of the flight. After the collection is completed, the motor 7 continues to rotate, so that the air guide cylinder 9 and the gear plate 11 drive the air storage cylinder gear ring 5 and the air intake cover 6 to rotate, thereby staggering the air inlet 17 and the air guide hole 10, and the air storage cylinder 3 is in a closed state.

[0037] Then it flies to the next target and drives the next gas storage cylinder 3 to store gas. After the operation is completed, it returns to the home, inserts the gas inlet nozzle of the gas cylinder used for transferring and collecting gas into the air guide groove 18, and drives the air inlet 17 to communicate with the air outlet 16 through the motor 7 to take out the collected gas.

[0038] On the basis of the above structure, in this embodiment, the gas storage assembly includes a spring cylinder 2, a gas storage cylinder 3, a gas storage cylinder gear ring 5 and an air inlet cover 6. One end of the gas storage cylinder 3 is provided with the spring cylinder 2, and the spring 14 is fixed by the provided spring cylinder 2. A top plate 15 is slidably connected inside the gas storage cylinder 3. A spring 14 is connected between the top plate 15 and the spring cylinder 2. By the cooperation of the top plate 15 and the spring 14, gas is extracted or extruded. On one side of the gas storage cylinder 3 away from the spring cylinder 2, the gas storage cylinder gear ring 5 that cooperates with the toothed plate 11 is rotatably connected. An air inlet cover 6 is provided on one side of the gas storage cylinder gear ring 5. An air inlet 17 that cooperates with the air guide hole 10 is opened on the air inlet cover 6. By driving the air inlet cover 6 to rotate through the gas storage cylinder gear ring 5, the air inlet 17 is driven to align with the air guide hole 10, thereby realizing air inlet and outlet.

[0039] On the basis of the above structure, in this embodiment, a polytetrafluoroethylene ring 8 that cooperates with the air guide cylinder 9 is arranged inside the housing 1. The provided polytetrafluoroethylene ring 8 plays a role of lubrication and fixation, enabling the air guide cylinder 9 to rotate inside the housing 1.

[0040] On the basis of the above structure, in this embodiment, a limiting groove 13 is opened inside the gas storage cylinder 3. A sliding block that is slidably connected with the limiting groove 13 is arranged on the outside of the top plate 15. By the cooperation of the provided limiting groove 13 and the sliding block, the top plate 15 can slide inside the gas storage cylinder 3.

[0041] On the basis of the above structure, in this embodiment, an air guide groove 18 that cooperates with the air outlet 16 is arranged inside the air guide cylinder 9 at the air outlet 16. Through the provided air guide groove 18, gas is introduced into the air outlet 16 under the action of wind pressure.

[0042] Embodiment 2

[0043] The spring 14 is in a contracted state. When the top plate 15 moves to a position close to the gas storage cylinder gear ring 5, the spring 14 is in a stretched state, and a sealing ring is arranged between the top plate 15 and the gas storage cylinder 3. Before takeoff, the trachea of the negative pressure air extraction device is inserted into the air outlet 16, thereby extracting the gas inside the gas storage cylinder 3, forcing the top plate 15 to approach the air inlet 17, and further stretching the spring 14.

[0044] When collecting gas, the air inlet 17 is communicated with the outside. At this time, the top plate 15 moves towards the spring cylinder 2 under the action of the spring 14 and forms a negative pressure, sucking external air into the gas storage cylinder 3 through the air inlet 17.

[0045] Although embodiments of the present utility model have been shown and described, the specific embodiments are merely explanations of the present utility model and not limitations thereof. The specific features, structures, materials, or characteristics described can be combined in a suitable manner in any one or more embodiments or examples. After reading this specification, those skilled in the art can make modifications, substitutions, and variations that do not make a creative contribution to the embodiments as needed, but as long as they are within the scope of the claims of the present utility model, they are protected by the patent law.
