Description

Technical Field

[0001] The invention relates to the technical field of unmanned aerial vehicles, and in particular to an agricultural unmanned aerial vehicle remote sensing monitoring device. Background Art

[0002] UAVs use sensors to collect electromagnetic wave information of target objects, identify targets after processing and analysis, and reveal their geometric, physical properties, relationships and laws of change. In other words, it is "remote perception". According to the sensor-carrying platform, it includes aerospace remote sensing, aviation remote sensing and ground remote sensing. The fields of use include natural disasters, such as national and local disaster monitoring, early warning, assessment, emergency rescue command systems, civil fields, etc. At the same time, the agricultural field will also use drone remote sensing monitoring on a large scale.

[0003] During the use of the agricultural UAV remote sensing monitoring device, the UAV is placed on an open space next to the designated point that needs to be detected, and then the UAV is flown over the designated area to cover the remote sensing monitoring through the camera, collect the required data, and finally fly back by remote control.

[0004] Most of the current agricultural UAV remote sensing monitoring devices do not have anti-sinking devices during use. Generally, UAVs are relatively expensive. If they accidentally fall into the air due to a concentration of birds or a sudden power outage or crash, it will be difficult to find them due to the long flight distance. If they fall to the bottom of the water, it will be even more difficult to find them, causing greater losses. Summary of the invention

[0005] The purpose of the present invention is to provide an agricultural UAV remote sensing monitoring device, which has the advantages of anti-sinking and easy retrieval, and solves the problems in the background technology.

[0006] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: an agricultural unmanned aerial vehicle remote sensing monitoring device, comprising a column, a mother buckle, a child buckle, a positive electrode, a negative electrode and a positive electrode block, an empty slot is opened inside the column, a bracket is fixedly connected to the bottom of the empty slot, an airbag is wrapped on the outside of the bracket, a condensate capsule is arranged inside the airbag, a puncture groove is opened on the top of the column, and a foam body is fixedly connected inside the hole groove; it also includes a puncture component fixedly connected to the top of the bracket, the puncture device can react chemically with the baking soda inside the condensate capsule, and the gas generated after the reaction can prompt the airbag to inflate and expand, and normalization is a stabilization device, but it will trigger further reaction once it involves gravity or external force impact; it also includes a trigger component fixedly connected to the inside of the column, the trigger device usually has two states: away and contact. Under normal conditions, it belongs to a away state, so that the mechanism will not be triggered to enter the next working state, and it will be further triggered and transformed to the contact state when encountering a special state.

[0007] Preferably, the puncture assembly comprises a block, the block is fixedly connected to the top of the bracket, and the outer wall of the bracket is provided with a plurality of mesh holes.

[0008] Preferably, six second springs are fixedly connected to the inner wall of the block, and thorns are fixedly connected to the center of the connection between the ends of the six second springs and the inner wall of the block, and also include a capsule punctured by the thorns. After the capsule is punctured, the liquid inside can flow out of the interior of the block through the mesh and contact with the bead capsule at the same time.

[0009] Preferably, the bag body comprises a liquid-containing bag, the liquid-containing bag is connected to the six end positions of the second springs, and citric acid liquid is arranged inside the liquid-containing bag.

[0010] Preferably, the trigger assembly includes a fixed block, which is fixedly connected to the inside of the column, one end of the fixed block is fixedly connected to a rotating shaft, the outside of the rotating shaft is rotatably connected to a top block, one side of the top block is fixedly connected to a metal sheet, and one end of the metal sheet is provided with a contact connected to the positive electrode block.

[0011] Preferably, a first spring is fixedly connected to one side of the metal sheet, a negative electrode block is fixedly connected to one end of the first spring, and the negative electrode block is fixedly connected to the inside of the column.

[0012] Preferably, a transparent cover is fixedly connected to the top of the column, a flashing light is arranged inside the transparent cover, and a battery slot is arranged on the top of the column.

[0013] Preferably, the trigger assembly includes a slide groove, which is opened inside the column, and a protrusion is slidably connected inside the slide groove, one end of the protrusion is fixedly connected to a power-carrying sheet, and the outside of the protrusion is sleeved with a third spring.

[0014] Compared with the prior art, the beneficial effects of the present invention are as follows: when the agricultural UAV remote sensing monitoring device is used, a card slot can be set inside the UAV body, and the column can be placed inside, and then it can be used with the UAV. For small aircraft, it can also be used with a female buckle. When the UAV is in the process of flight remote sensing monitoring, if an accidental fall occurs, the power is cut off and the connection is lost, the UAV will fall quickly to the water surface or the ground surface. At that moment, the liquid capsule squeezes the second spring under the action of gravity. After the second spring contracts, the liquid capsule contacts the thorn and is then punctured. The citric acid inside flows out through the mesh inside the block and combines with the condensate capsule. The condensate capsule encounters liquid and dissolves. At the same time, the baking soda inside combines with the citric acid to produce a large amount of gas. Then the gas fills the entire interior of the airbag and squeezes the foam body and the top block under pressure at the same time. When the foam body is squeezed, the airbag continues to expand through the hole groove so that the UAV will not sink to the bottom of the water under the action of buoyancy. When the top block is squeezed, the contact at the end of the metal sheet contacts the positive electrode block to form a closed circuit so that the flashing light starts to flash, and it is easy to find.

[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0023] See also Figures 1 to 6 The present invention provides a technical solution: an agricultural UAV remote sensing monitoring device, comprising a column 1, a female buckle 26, a positive electrode 24, a negative electrode 27 and a positive electrode block 9, the column 1 is provided with an empty groove inside, the bottom of the empty groove is fixedly connected with a bracket 6, the outside of the bracket 6 is wrapped with an air bag 5, the inside of the air bag 5 is provided with a condensation bead capsule 28, the top of the column 1 is provided with a breakable hole groove 3, the inside of the hole groove 3 is fixedly connected with a foam body 4.

[0024] It also includes a puncturing component fixedly connected to the top of the bracket 6. The puncturing device can react chemically with the baking soda inside the bead capsule 28. The gas generated after the reaction can prompt the airbag 5 to inflate and expand. Normalization is a stabilizing device, but once it involves gravity or external force impact, it will trigger further reaction. Then, during the stabilization process, there will be no overflow of the internal components, avoiding contact with the baking soda inside the airbag 5, thereby playing an isolating and stabilizing role.

[0025] It also includes a trigger component fixedly connected to the inside of the column 1. The trigger device usually has two states: away and in contact. Under normal conditions, it belongs to a away state, so that the mechanism will not be triggered to enter the next working state, which plays a role of protection and isolation. Only when encountering a special state will it be further triggered to change to the contact state. When the contact state is formed, a closed circuit will be formed, thereby achieving the purpose of the final contact state, and the flashing light 8 will start to work and flash.

[0026] The inner wall of the hole groove opened inside the column 1 is rounded without any edges and corners, and the edge of the hole groove 3 opened on the top is also rounded. The purpose of this is to prevent the airbag 5 from being punctured during the expansion of the hole groove 5 and the inner wall of the empty groove. At the same time, the connection between the foam body 4 fixedly connected inside the hole groove 5 is a crack connection. When the inside is slightly subjected to the pressure applied by the expansion of the airbag 5, the foam body 4 will separate from the hole groove 5. The foam body 4 can also be set to a relatively brittle film. The purpose is to make it easier for the airbag 5 to break through the hole groove 3. The hardness of the film can be adjusted in combination with the experimental test results to achieve both a sealing effect and easy push-open breakthrough under special circumstances. At the same time, a convex block is also set at the bottom of the foam body 4. The purpose is to apply concentrated pressure to the foam body 4 when the airbag 5 expands to facilitate breakthrough.

[0027] The puncture component will set a gravity critical value based on experiments. When the drone is accelerating and falls to contact the bottom or the lake surface, the critical value will be exceeded under the action of gravity, and the puncture component will puncture the liquid bag 19. When there is only a slight vibration, the second spring 17 inside the puncture component will play a protective role. The puncture component can be disassembled and assembled at ordinary times, so that the internal components can be replaced after multiple uses, which is convenient for maintenance and can also reduce the cost of use.

[0028] The trigger component is actually a connecting device, which can only be driven to work when the former puncture component works. When the puncture component takes effect, the airbag 5 will be inflated. While inflating, it will generate pressure toward the outside inside the column 1, and then squeeze the top block 15, so that the connecting device produces a connecting effect. When the trigger component does not take effect, the normal state of the trigger component is a disconnected state. The trigger component can also be a slot fixedly installed inside the column 1, which can meet the use under specific conditions and can also meet the replacement and maintenance under daily circumstances. However, there must be waterproof measures at the sealing point to avoid liquid leakage, in order to ensure the integrity of its circuit.

[0029] Embodiment 1:

[0030] In one of the more preferred embodiments, the puncture component includes a block 7, and the block 7 is fixedly connected to the top of the bracket 6. The outer wall of the bracket 7 is provided with a plurality of mesh holes 16. The block 7 is also an isolation device, which isolates the bead capsule 28 from contacting the inside of the block 7 from the outside. Only when the puncture component takes effect, the liquid inside the block 7 will flow out from the plurality of mesh holes 16 and contact the bead capsule 28. The block 7 is a carrier. Other shapes such as columns or cylinders that can meet the conditions are also acceptable, and the stability can be adjusted accordingly. Targeted modifications can be made based on the experimental results.

[0031] like Figure 5 As shown, six second springs 17 are fixedly connected to the inner wall of the block 7, and a thorn 18 is fixedly connected to the center of the connection between the ends of the six second springs 17 and the inner wall of the block 7, and also includes a capsule pierced by the thorn 18. After the capsule is pierced, the liquid inside can flow out of the interior of the block 7 through the mesh 16 and contact with the bead capsule 28 at the same time. The main function of the six second springs 17 is to stabilize the liquid capsule 19. The radius of the six second springs can be adjusted appropriately so that the six surfaces inside the block 7 can fix it firmly, and at the same time, it is also necessary to ensure that the liquid inside the liquid capsule has enough weight and produces enough gas.

[0032] The capsule body includes a liquid-containing capsule 19, which is connected to the six end positions of the second springs 17. Citric acid liquid is arranged inside the liquid-containing capsule 19. When the citric acid liquid contacts baking soda, a large amount of gas is generated, thereby expanding the airbag 5 wrapped outside. When subjected to gravity, the liquid-containing capsule 19 applies pressure to the second spring 17, and the second spring 17 begins to shrink. At the same time, the spur 17 contacts the liquid-containing capsule 19 for piercing. The liquid-containing capsule 19 and citric acid will produce a chemical reaction to produce a large amount of gas. Other reagents that produce stronger gas can also be used as a substitute. However, during use, care must be taken to avoid corrosion of the second spring 17. If other chemical reactions are to be avoided, the second spring 17 can also be replaced with a plastic structure.

[0033] Based on the first embodiment, an embodiment of a pressure trigger component is provided:

[0034] like Figure 3 As shown, the trigger assembly includes a fixed block 14, which is fixedly connected to the inside of the column 1, one end of the fixed block 14 is fixedly connected to the rotating shaft 13, the outside of the rotating shaft 13 is rotatably connected to the top block 15, one side of the top block 15 is fixedly connected to a metal sheet 12, one end of the metal sheet 12 is provided with a contact connected to the positive electrode block 9, the fixed block 14 is a detachable fixed block, and can also be a connecting block used to allow the top block 15 to be rotatably connected inside the column 1, one side of the top block 15 is fixedly connected to the metal sheet 12, and the conductive performance of the metal sheet 12 must be relatively strong and the conductive performance is good.

[0035] A first spring 11 is fixedly connected to one side of the metal sheet 12, and a negative electrode block 10 is fixedly connected to one end of the first spring 11. The negative electrode block 10 is fixedly connected to the inside of the column 1. When the trigger component is in a normal state, the contact on the metal sheet 12 is away from the positive electrode block 9 under the action of the first spring 11. Only when the top block 15 is subjected to a squeezing force, the contact on the metal sheet 12 will contact the positive electrode block 9, thereby forming a closed circuit flashing light 8 to flash. The flashing light 8 is a new energy-saving lamp body with a flashing brightness or other low energy consumption and relatively high brightness, which can facilitate people to track its designated position at a long distance.

[0036] A transparent cover 2 is fixedly connected to the top of the column 1, and a flashing light 8 is arranged inside the transparent cover 2. A battery slot 23 is arranged on the top of the column 1. The flashing light 8 forms a closed circuit with the positive block 9 and the negative block 10 at the same time. The battery slot 23 is used for normal backup batteries. Some drying equipment and waterproof measures can be attached inside. Some edges and corners can be set inside the transparent cover 2 to facilitate the divergence of the light of the flashing light 8, and increase its brightness and appearance through the principle of refraction. The connection between the transparent cover 2 and the column 1 is in a sealed state or a threaded connection with a sealing ring structure, mainly to achieve a waterproof effect. The flashing light forms a complete closed circuit with the positive block 8 and the negative block 10 at the same time, and the path of the entire closed circuit is set inside the column 1, and is set to a waterproof structure to avoid any impact on the circuit when it is in water.

[0037] Embodiment 2:

[0038] like Figure 6 In one of the more preferred embodiments, the trigger component includes a slide groove 29, which is opened inside the column 1, and the inside of the slide groove 29 is slidably connected with a protrusion 20, one end of the protrusion 20 is fixedly connected with a power-carrying piece 22, and the outside of the protrusion 20 is sleeved with a third spring 21. The slide groove 29 belongs to the concept of an annular channel, and the inner wall and the entrance are relatively smooth to facilitate the sliding of the protrusion 20 inside. At the same time, the power-carrying piece 22 is equivalent to the effect of the metal sheet 12, and its purpose and function are to conduct electricity to form a closed circuit. Some edges can be appropriately arranged on the outside of the power-carrying piece 22 to prevent displacement during the conductive contact process, so as to achieve the effect of smooth conduction.

[0039] When the trigger assembly is in a normal state, the power-carrying piece will not contact the positive electrode 24 and the negative electrode 27. Since the third spring 21 is provided on the outside of the protrusion 20 for limiting, the power-carrying piece fixedly connected to the bottom of the protrusion 20 is normally away from the positive electrode 24 and the negative electrode 27. Only when the puncture assembly works, the airbag 5 expands and further squeezes the protrusion 20 so that the protrusion 20 slides along the inside of the column 1 until the power-carrying piece 22 contacts the positive electrode 24 and the negative electrode 27 to form a series connection and a closed circuit. Some edges are provided at the ports of the positive electrode 24 and the negative electrode 27 to facilitate good contact. They can be set to a snap-in state, but the resistance will be larger. However, the best effect of the snap-in state is that when the airbag 5 is punctured by foreign objects, the integrity of the closed circuit can also be guaranteed. Then the flashing light 8 still flashes normally, which is convenient for people to find.

[0040] Based on the second embodiment, an embodiment of a gravity puncture assembly is provided:

[0041] The puncture component includes a block 7, and the block 7 is fixedly connected to the top of the bracket 6. The outer wall of the bracket 7 is provided with a plurality of mesh holes 16. The block 7 is also an isolation device, which isolates the bead capsule 28 from contacting the inside of the block 7 from the outside. Only when the puncture component takes effect, the liquid inside the block 7 will flow out from the plurality of mesh holes 16 and contact the bead capsule 28. The bracket 6 can be set as a relatively low fixed block, or even not required, and the block 7 can be directly fixedly connected to the bottom of the column 1. However, the bottom fixed connection needs to be set to a gentle slope to facilitate the liquid not to stay inside the block 7 and to overflow quickly.

[0042] like Figure 5 As shown, six second springs 17 are fixedly connected to the inner wall of the block 7, and a thorn 18 is fixedly connected to the center of the connection between the ends of the six second springs 17 and the inner wall of the block 7. It also includes a capsule punctured by the thorn 18. After the capsule is punctured, the liquid inside can flow out of the interior of the block 7 through the mesh 16 and contact the bead capsule 28 at the same time.

[0043] The capsule body includes a liquid-containing capsule 19, which is connected to the end positions of the six second springs 17. Citric acid liquid is arranged inside the liquid-containing capsule 19. When the citric acid liquid comes into contact with baking soda, a large amount of gas is generated, thereby expanding the airbag 5 wrapped outside. When subjected to gravity, the liquid-containing capsule 19 applies pressure to the second spring 17, and the second spring 17 begins to shrink. At the same time, the spur 17 contacts the liquid-containing capsule 19 for piercing. The outer wall of the liquid-containing capsule 19 is made of a relatively elastic material, which ensures that it will not be easily punctured by a slight movement. The positions where the end positions of the six second springs 17 contact the liquid-containing capsule 19 can be set to a relatively blunt state, or can be a spring body with flocking at the end, to ensure that the six springs 17 will not puncture the liquid-containing capsule 19 except for the spur 18, thereby ensuring the integrity of the liquid-containing capsule 19 in the event of a subsequent accident.

[0044] The difference from the implementation method in Example 1 is that the contact method for closing the circuit is different, and the structural methods used are also different. In the first embodiment, the metal sheet 12 is an end contact contact, which may cause insufficient contact. The current power-carrying sheet 22 is a whole-piece contact to form a closed circuit. Therefore, compared with the first contact method, it is relatively more comprehensive and reliable, the effect of contacting the closed circuit is better, and the required components are simpler.

[0045] Working principle: When the agricultural UAV remote sensing monitoring device is used, a slot can be set inside the UAV body, and the column 1 can be placed inside, and then it can be used with the UAV. For small aircraft, it can also be used with the female buckle 26. When the UAV is in the process of remote sensing monitoring, if an accidental fall occurs, the power is cut off and the connection is lost, the UAV will fall quickly to the water surface or the ground surface. At that moment, the liquid capsule 19 squeezes the second spring 17 under the action of gravity, and the second spring 17 After contraction, the liquid-containing capsule 19 contacts the spur 18 and is then punctured, and the citric acid inside flows out through the mesh 16 inside the block 7 and combines with the bead capsule 28. The bead capsule 28 dissolves when it encounters the liquid, and at the same time, the baking soda inside combines with the citric acid to produce a chemical reaction to produce a large amount of gas. The gas then fills the entire interior of the airbag 5 and squeezes the foam body 4 and the top block 15 under pressure. When the foam body 4 is squeezed, the airbag 5 continues to expand through the hole groove 3 so that the drone will not sink to the bottom of the water under the action of buoyancy. When the top block 15 is squeezed, the contact at the end of the metal sheet 12 contacts the positive electrode block, forming a closed circuit so that the flashing light 8 starts to flash, which is also convenient for finding.

[0046] The standard parts used in this embodiment can be purchased directly from the market, and the non-standard structural components recorded in the specification and the drawings can also be directly processed according to the existing technical common sense. At the same time, the connection method of each component adopts the mature conventional means in the prior art, and the machinery, parts and equipment all adopt the conventional models in the prior art, so no specific description will be given here.

[0047] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
