Description

Technical Field

[0001] The present invention relates to the technical field of unmanned aerial vehicles (UAVs), and in particular to a marine inspection UAV. Background Art

[0002] Unmanned aerial vehicle, abbreviated as "UAV" in English, is an unmanned aircraft controlled by radio remote control equipment and self-contained program control devices, or operated completely or intermittently autonomously by an on-board computer. Compared with manned aircraft, UAVs are often more suitable for dangerous tasks, such as maritime inspections; and during maritime inspections, due to the complex marine environment, it is easy to encounter strong winds and waves, which may cause the UAV to crash. It may also fall directly into the sea when encountering interference or running out of power. Unlike falling on land, falling into the sea will sink directly to the bottom of the sea, making it difficult to find.

[0003] At present, in order to avoid sinking directly to the seabed, the existing drone, when in use, uses the reaction block to react with seawater to generate carbon dioxide gas, and injects the gas into the airbag, and then uses the airbag to make the drone float on the water surface. In the process of introducing the seawater into the reaction chamber to contact the reaction block, it directly introduces the seawater into it and reacts with the reaction block, thereby completing the inflation of the airbag;

[0004] However, with the above structure, when in use, seawater directly enters the reaction chamber to react with the reaction block, and the released gas has more than one flow channel, which reduces the utilization rate of the released gas and makes it impossible to inflate the airbag. As a result, the airbag cannot effectively support the drone and there is a risk of sinking to the bottom of the sea. Summary of the invention

[0005] Based on this, the purpose of the present invention is to provide a marine inspection drone to solve the technical problem that in the prior art, when in use, seawater directly enters the reaction chamber to react with the reaction block, and the released gas has more than one flow channel, which reduces the utilization rate of the released gas and cannot meet the inflation of the airbag. As a result, the airbag cannot effectively support the drone and there is a risk of sinking to the bottom of the sea.

[0006] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a marine inspection drone, comprising a drone body, a mounting groove is provided on the outer side of the bottom of the drone body, a safety bag is installed inside the mounting groove, a water inlet chamber is uniformly provided on the outer side of the drone body, a reaction chamber and a transition chamber are provided inside the drone body, the reaction chamber and the water inlet chamber are connected to each other, a closed guide channel matching the water inlet chamber is uniformly provided inside the drone body, and a sealing component is provided inside the closed guide channel, a connecting pipe is connected between the transition chamber and the safety bag, a water injection chamber connected to the water inlet chamber is provided inside the drone body, a moving component is provided inside the water injection chamber, a starting plate connected to the moving component is provided on the top of the drone body, a plurality of waterproof light strips matching the starting plate are uniformly provided inside the top of the drone body, a magnetic switch component is provided on the drone body and the starting plate, and a reaction block is provided inside the reaction chamber.

After the above process, the effect of the sealing component is utilized, so that after the reaction block reacts in the reaction chamber, the seawater is not easy to flow into the safety bag, thereby avoiding the reduction of the use effect of the safety bag, and further ensuring the safety of the drone body after falling into the water.

[0008] The present invention is further configured such that the sealing assembly comprises a first floating plate and a sealing block, the first floating plate and the sealing block are respectively arranged on the upper and lower parts of the closed guide channel, and the first floating plate and the sealing block are connected via a connecting column.

[0009] By adopting the above technical solution and utilizing the effects of the first floating plate and the sealing block, when there is too much water in the reaction chamber, it is ensured that no more water enters the water inlet chamber, so as to facilitate subsequent work.

[0010] The present invention is further configured such that the moving assembly includes a second floating plate and a support rod, the second floating plate is disposed inside the water injection cavity, and the top of the second floating plate is provided with a support rod connected to the starting plate.

[0013] By adopting the above technical solution, the first magnetic block is used to cooperate with the second magnetic block to operate the closing and separation between the first contact and the second contact, so that the waterproof light strip is automatically lit to complete the work.

[0014] The present invention is further configured such that a symmetrical downpipe is connected between the reaction chamber and the water inlet chamber, a first one-way valve is arranged inside the downpipe, and an air inlet pipe is connected between the transition chamber and the reaction chamber, a second one-way valve is arranged inside the air inlet pipe.

[0015] By adopting the above technical solution, the reaction chamber and the water inlet chamber are connected by utilizing the function of the downpipe so as to complete the water injection, and the direction of the water flow is controlled by utilizing the function of the first one-way valve to prevent the backflow of seawater, and the released carbon dioxide gas is introduced into the transition chamber by utilizing the function of the air inlet pipe, and the gas backflow is prevented by utilizing the function of the second one-way valve.

[0022] In summary, the present invention mainly has the following beneficial effects:

[0023] 1. When the present invention is in use, the water inlet chamber is used to allow seawater to quickly enter the reaction chamber, and enter the closed guide channel along the connecting hole, and cooperate with the first floating plate to move the sealing block upward until the inside of the water inlet chamber is sealed, thereby preventing seawater from entering the reaction chamber. In the above process, a reaction occurs in the reaction chamber to generate gas, and because the water inlet chamber is closed, the generated gas can only enter the transition chamber and finally be injected into the safety bag.

[0034] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0035] The following describes an embodiment of the present invention based on its overall structure.

[0036] A marine inspection drone, such as Figure 1-8As shown, it includes a drone body 1, a mounting groove 2 is provided on the outer side of the bottom of the drone body 1, a safety bag 3 is installed inside the mounting groove 2, a water inlet chamber 8 is uniformly provided on the outer side of the drone body 1, a reaction chamber 9 and a transition chamber 10 are provided inside the drone body 1, the reaction chamber 9 and the water inlet chamber 8 are communicated with each other, a closed guide channel 12 is uniformly provided inside the drone body 1 to match the water inlet chamber 8, and seawater is quickly introduced into the reaction chamber 9 by means of the water inlet chamber 8, and enters into the closed guide channel 12 along the connecting hole 24, and a sealing component is provided inside the closed guide channel 12, and the sealing component is cooperated to make the sealing block 14 move upward until the inside of the water inlet chamber 8 is sealed, thereby preventing seawater from entering the reaction chamber 9, a connecting pipe 11 is connected between the transition chamber 10 and the safety bag 3, a reaction occurs in the reaction chamber 9 to generate gas, and since the water inlet chamber 8 is closed, the generated gas can only enter into the transition chamber 10, and finally be injected into the safety bag 3, which has a high gas utilization rate and fully opens the safety bag 3 to prevent seawater from entering the reaction chamber 9. This ensures the safety of the drone body 1. A water injection chamber 20 connected to the water inlet chamber 8 is provided inside the drone body 1. By utilizing the function of the water inlet channel 25, seawater will quickly enter the water injection chamber 20. A moving component is provided inside the water injection chamber 20. With the help of the moving component, the starting plate 5 is opened from the top of the drone body 1, so that the waterproof light belt 23 is exposed, and the waterproof light belt 23 is activated by the function of the magnetic switch component 26 to make it emit light so that the searcher can find it. After the above process, the top of the drone body 1 is equipped with a starting plate 5 connected to the moving component, and multiple groups of waterproof light belts 23 matched with the starting plate 5 are evenly arranged inside the top of the drone body 1. The drone body 1 and the starting plate 5 are equipped with a magnetic switch component 26. A reaction block 16 is provided inside the reaction chamber 9. By utilizing the function of the sealing component, after the reaction block 16 reacts in the reaction chamber 9, seawater is not easy to flow into the safety bag 3, thereby avoiding the use effect of the safety bag 3 from being reduced, and further ensuring the safety of the drone body 1 after falling into the water.

[0037] See also Figure 2 and Figure 4 The sealing assembly includes a first floating plate 13 and a sealing block 14. The first floating plate 13 and the sealing block 14 are respectively arranged on the upper and lower parts of the closed guide channel 12, and the first floating plate 13 and the sealing block 14 are connected by a connecting column. By utilizing the function of the first floating plate 13 and the sealing block 14, when there is too much water in the reaction chamber 9, it is ensured that the water inlet chamber 8 no longer enters the water, so as to cooperate with subsequent work.

[0038] See also Figure 2 and Figure 3The moving component includes a second floating plate 18 and a support rod 19. The second floating plate 18 is arranged inside the water injection chamber 20. The top of the second floating plate 18 is provided with a support rod 19 connected to the starting plate 5. By utilizing the action of the second floating plate 18 and the support rod 19 and cooperating with the action of water, the starting plate 5 can be automatically opened to cooperate with subsequent work.

[0039] See also Figure 8 The magnetic switch assembly 26 includes a first magnetic block 2601, a matching seat 2602, a first contact 2603, a second magnetic block 2604 and a second contact 2605. The first magnetic block 2601 is evenly arranged at the bottom of the start plate 5, and the matching seat 2602 matching with the first magnetic block 2601 is arranged on the top of the drone body 1. The first contact 2603 is arranged inside the matching seat 2602. The top of the first contact 2603 is provided with a second magnetic block 2604 matching with the first magnetic block 2601, and the matching seat 2602 is provided with a second contact 2605 matching with the first contact 2603. The first magnetic block 2601 is used to facilitate the matching with the second magnetic block 2604, so that it can operate the closing and separation between the first contact 2603 and the second contact 2605, so that the waterproof light strip 23 is automatically lit, so as to complete the work.

[0040] See also Figure 4 A symmetrical downpipe 15 is connected between the reaction chamber 9 and the water inlet chamber 8. The downpipe 15 is used to connect the reaction chamber 9 and the water inlet chamber 8 so as to complete the water injection. A first one-way valve 17 is arranged inside the downpipe 15. The first one-way valve 17 is used to control the direction of the water flow and prevent the seawater from flowing back. An air inlet pipe 21 is connected between the transition chamber 10 and the reaction chamber 9. A second one-way valve 22 is arranged inside the air inlet pipe 21. The air inlet pipe 21 is used to introduce the released carbon dioxide gas into the transition chamber 10, and the second one-way valve 22 is used to prevent the gas from flowing back.

[0041] See also Figure 2 A drone parts installation cavity 7 is provided inside the drone body 1 to ensure the integrity of the device.

[0042] See also Figure 1 A groove 6 matching the launch plate 5 is provided on the top of the drone body 1, and anti-dropping protrusions 4 are provided at the upper and lower edges of the mounting groove 2. The groove 6 is used to facilitate the installation and engagement of the launch plate 5, and the anti-dropping protrusions 4 are used to ensure that the safety bag 3 is not easy to fall off.

[0043] See also Figure 6The reaction chamber 9 and the closed guide channel 12 are both connected by a connecting hole 24, and the water inlet chamber 8 and the water injection chamber 20 are both connected by a water inlet channel 25. The connecting hole 24 and the water inlet channel 25 ensure that the two are connected to each other so as to complete the subsequent work.

[0044] The working principle of the present invention is as follows: when the drone body 1 falls into the water, the water inlet chamber 8 is tilted to allow seawater to quickly enter the chamber, and the water down pipe 15 and the first one-way valve 17 are used to allow seawater to only enter but not exit, that is, the seawater quickly enters the reaction chamber 9. At this time, the seawater contacts and reacts with the reaction block 16, releasing a large amount of carbon dioxide gas, which is matched with the second one-way valve 22 along the air inlet pipe 21, so that the gas can only enter but not exit. In this way, the carbon dioxide enters the transition chamber 10 along the air inlet pipe 21, and finally enters the safety bag 3 through the connecting pipe 11, so that it expands rapidly and is in an inflated state, so that the drone body 1 floats on the sea surface. This process is simple and fast.

[0045] During the continuous reaction of the reaction chamber 9, seawater continues to enter the reaction chamber 9 and enters the closed guide channel 12 along the connecting hole 24. At this point, the sealing assembly is started, that is, the sealing block 14 is quickly moved upward by the buoyancy of the first floating plate 13 in the water to seal the corresponding water inlet chamber 8, thereby preventing seawater from entering the reaction chamber 9 along the downpipe 15. Since the reaction of the reaction block 16 with seawater requires consumption of seawater, the sealing block 14 is continuously closed and opened until the reaction of the reaction block 16 is completely completed, and at this time the safety bag 3 is fully opened, and the sealing block 14 is completely sealed;

[0046] During this process, seawater will also flow into the water injection chamber 20 along the water inlet channel 25, and cooperate with the second floating plate 18 to move the starting plate 5 upward until it is disengaged from the groove 6, so that the waterproof light strip 23 is exposed, and at the same time, the waterproof light strip 23 is opened by utilizing the action of the magnetic switch assembly 26, that is, when the starting plate 5 moves upward, it will drive the first magnetic block 2601 to disengage from the matching seat 2602, so that the first magnetic block 2601 cannot act on the second magnetic block 2604, so that the second magnetic block 2604 falls, and the first contact 2603 contacts the second contact 2605, thereby starting the waterproof light strip 23 and making it emit light so that the searcher can find it.
