[0002] Natural disasters (such as earthquakes, floods, mudslides, etc.) often bring devastating destruction, such as serious road damage and severe damage to infrastructure such as power supply and fuel supply. In this case, the disaster area urgently needs to restore power supply, ensure vehicle mobility and the normal operation of rescue machinery in order to carry out emergency rescue and post-disaster reconstruction. Fuel is the key energy source for the operation of these equipment, and its supply issue is particularly important.

[0003] In the case of insufficient road resources (damaged roads) or high ground transportation costs (mountainous environments), transporting fuel by air is a more reliable solution. Existing technologies mainly use helicopters to drop fuel supplies such as oil sacs and oil drums. However, this method cannot guarantee the accuracy of the location where the fuel tanks or oil sacs are dropped. Since the disaster-stricken areas often have complex terrain, a slight deviation in the landing point may cause the oil sacs or oil drums to fall in difficult-to-access places, causing great inconvenience for subsequent retrieval and use. In addition, helicopters require professional pilots to fly, and the training and use costs are high, which carries certain risks. Summary of the invention

[0023] Please also read Figures 1 to 6Now, a rescue fuel transportation device provided by the present invention is described. The rescue fuel transportation device includes a drone 10, a hoisting frame 20, a fuel tank 30 and a quick connector 40. The drone 10 has a sensing module and a communication module. The bottom of the drone 10 is provided with a support leg 11 and a clamping assembly 12 located at the bottom of the support leg 11; the hoisting frame 20 has a suspension rod 21 that cooperates with the clamping assembly 12; the fuel tank 30 is connected to the hoisting frame 20, and the fuel tank 30 has a detection module 33 and a recording module 34. The detection module 33 is used to detect the remaining fuel amount, and the recording module 34 is used to record and send fuel type information and the position of the fuel tank 30. The detection module 33 and The recording modules 34 are all connected to the sensing module in communication; the quick connector 40 is arranged at the bottom of the oil tank 30 and extends out of the hanging frame 20, the quick connector 40 includes a shell 41, a blocking block 42 that is slidably matched in the shell 41 along the up and down directions, and a reset mechanism arranged in the shell 41, the lower end inner wall of the shell 41 is provided with a first inclined cone surface 411, the inner diameter of the first inclined cone surface 411 gradually decreases from top to bottom, the blocking block 42 is provided with a second inclined cone surface 421 adapted to the first inclined cone surface 411, and the reset mechanism is used to push the blocking block 42 so that the second inclined cone surface 421 abuts against the first inclined cone surface 411; When the oil tank 30 is refueling other equipment, or the oil tank 30 needs to be refilled, the sealing block 42 is pushed to separate the first inclined cone surface 411 and the second inclined cone surface 421, and the oil passes through the gap between the first inclined cone surface 411 and the second inclined cone surface 421. After use, the reset mechanism drives the sealing block 42 to move downward until the second inclined cone surface 421 abuts against the first inclined cone surface 411.

[0024] The use process of the rescue fuel transportation device provided in this embodiment is as follows: after the fuel tank 30 is connected to the hanging frame 20, the hanging frame 20 is clamped by the clamping assembly 12 at the bottom of the drone 10, and the fuel tank 30 can be transported by flying the drone 10. During the transportation process, the recording module 34 can transmit the position information of the fuel tank 30 to the sensing module on the drone 10, and the drone 10 transmits the position information of the fuel tank 30 to the person who remotely controls the drone 10 and the person who receives the rescue materials through the communication module. When the fuel tank 30 reaches the designated position, the clamping assembly 12 on the drone 10 releases the fuel tank 30 and the drone 10 can fly on its own. After the personnel receiving the materials find the fuel tank 30 according to the location information of the fuel tank 30, they can determine the amount and specifications of the oil in the fuel tank 30 according to the detection module 33 and the recording module 34 on the fuel tank 30, so as to facilitate use. When it is necessary to take oil from the fuel tank 30, the blocking block 42 can be pushed upward. At this time, the blocking block 42 slides upward to separate the second inclined cone surface 421 and the first inclined cone surface 411, and the oil in the fuel tank 30 can flow out from the gap between the first inclined cone surface 411 and the second inclined cone surface 421. After use, the reset mechanism automatically resets the blocking block 42, and the first inclined cone surface 411 and the second inclined cone surface 421 abut against each other to prevent the oil from continuing to flow out.

[0025] Compared with the prior art, the rescue fuel transportation device of the present invention adopts a drone 10 to transport the fuel tank 30, which is convenient for remote control, does not require professional pilots to operate, has lower training and use costs, and reduces risks accordingly; a clamping assembly 12 is provided on the drone 10 to facilitate the grabbing and releasing of the fuel tank 30, which can be released after flying to a designated point. Compared with airdrop, the location of the release is more accurate; the detection module and recording module 34 on the fuel tank 30 can accurately record information such as the amount of oil in the fuel tank 30, the type of fuel, and the location of the fuel tank 30, so that the recipient can quickly obtain information about the fuel tank 30, thereby finding the most suitable fuel tank 30 for use; by providing a quick connector 40 on the fuel tank 30, it is convenient to quickly take out oil, which is more convenient to use and simpler to operate.

[0026] Specifically, a conventional refueling port 32 is further provided on the top of the fuel tank 30, and a fuel tank 30 cap is tightened on the conventional refueling port 32. When the fuel tank 30 is not installed on the drone 10, if oil is to be added to the fuel tank 30, the fuel tank 30 can be inverted and the oil can be added to the inside through the quick connector 40; if the fuel tank 30 is installed on the drone 10, it is not convenient to invert the fuel tank 30 at this time, and the fuel tank 30 cap can be unscrewed and the oil can be added to the inside through the conventional refueling port 32.

[0027] In some embodiments, a specific implementation of the above-mentioned reset mechanism can be as follows: Figure 5 See the structure shown. Figure 5 A guide plate 44 is provided on the inner side of the upper end of the housing 41. The guide plate 44 is provided with a central hole and through holes 45 evenly distributed on the periphery of the central hole. The through holes 45 are used to allow oil to pass through; a guide rod 46 is fixedly connected to the blocking block 42, and the guide rod 46 slides with the central hole; the reset mechanism is a reset spring 43 sleeved on the guide rod 46, and the two ends of the reset spring 43 are respectively abutted against the guide plate 44 and the blocking block 42.

[0028] When the blocking block 42 is pushed, the blocking block 42 abuts against the return spring 43, causing the return spring 43 to be compressed. At this time, the second inclined cone surface 421 on the outer periphery of the blocking block 42 is separated from the first inclined cone surface 411, and the oil in the oil tank 30 can flow out through the through hole 45, the first inclined cone surface 411 and the gap between the second inclined cone surface 421 in sequence. When the blocking block 42 is released, the return spring 43 rebounds, pushing the blocking block 42 to move downward until the second inclined cone surface 421 abuts against the first inclined cone surface 411.

[0029] This structure can realize the automatic resetting of the blocking block 42. After the blocking block 42 is no longer pushed, the blocking block 42 can quickly return to its original position, thereby blocking the oil in time and avoiding the waste of the oil.

[0030] In some embodiments, an improved matching method of the blocking block 42 and the return spring 43 can be as follows: Figure 5 See the structure shown. Figure 5 The blocking block 42 is provided with a recessed groove 422 on one side facing the guide plate 44, and one end of the return spring 43 near the blocking block 42 extends into the recessed groove 422. The return spring 43 is sleeved on the outer periphery of the guide rod 46 to guide the expansion and contraction process of the return spring 43, and one end of the return spring 43 near the blocking block 42 extends into the recessed groove 422, so as to realize the positioning between the return spring 43 and the blocking block 42.

[0031] In some embodiments, an improved implementation of the blocking block 42 may be as follows: Figure 5 See the structure shown. Figure 5 The second oblique conical surface 421 is provided with a concave annular groove, and a first sealing ring 47 is provided in the annular groove. The first sealing ring 47 is used to abut against the first oblique conical surface 411. By providing the first sealing ring 47 on the second oblique conical surface 421, the sealing effect between the first oblique conical surface 411 and the second oblique conical surface 421 can be improved, and energy waste caused by oil leakage can be avoided.

[0032] As a variation, a concave annular groove and a first sealing ring 47 may also be provided on the first oblique conical surface 411 , and either the first oblique conical surface 411 or the second oblique conical surface 421 may be provided.

[0033] In some embodiments, an improved embodiment of the housing 41 may be as follows: Figure 5 See the structure shown. Figure 5 The outer side of the lower end of the housing 41 is provided with a plug-in groove, and the inner wall of the plug-in groove is provided with a second sealing ring 48. When the external interface is connected to the quick connector 40, it can be plugged in with the plug-in groove on the housing 41, and the structure corresponding to the blocking block 42 on the external interface can automatically abut the blocking block 42 after plugging. In this process, the second sealing ring 48 can ensure the sealing of the connection between the external interface and the quick connector 40 to avoid oil leakage.

[0034] In some embodiments, an improved embodiment of the housing 41 may be as follows: Figure 5 See the structure shown. Figure 5 The outer periphery of the housing 41 is also provided with a limit plate 49, and the limit plate 49 is spaced below the hanging frame 20. By arranging the limit plate 49 on the housing 41, the insertion depth when the external interface and the quick connector 40 are docked can be limited, and it is more convenient to use.

[0035] In some embodiments, a specific implementation of the above-mentioned hanging bracket 20 can be as follows Figures 2 to 3 See the structure shown. Figures 2 to 3, horizontally arranged slide rails 31 are provided on opposite sides of the oil tank 30, and the hoisting frame 20 includes two hoisting assemblies, and the two hoisting assemblies are respectively connected to the two slide rails 31 in one-to-one correspondence, and each hoisting assembly includes at least two suspension rods 21 and connecting rods 22, and multiple suspension rods 21 are slidably matched with the same slide rail 31; the connecting rod 22 is detachably connected to the top of multiple suspension rods 21, and the connecting rod 22 is connected to the clamping assembly 12. The suspension rod 21 can be slidably adjusted on the slide rail 31, which is convenient for adjusting the position of the suspension rod 21 on the slide rail 31. After the suspension rod 21 is installed, the connecting rod 22 is connected to multiple suspension rods 21 to complete the assembly of a suspension assembly. This structure is convenient for assembly and disassembly. After the oil tank 30 is transported to a location, the suspension rod 21 and the connecting rod 22 can be disassembled and used as a rescue tool.

[0036] Optionally, the suspension rod 21 and the connecting rod 22 may be connected by means of snap connection, plug connection, threaded connection, etc.

[0037] It should be noted that the cross-sectional shape of the slide rail 31 is irregular, and the corresponding sliding holes of the corresponding hanger 21 and the slide rail 31 are also irregular. The hanger 21 can slide on the slide rail 31 by pushing strongly between the hanger 21, but when the hanger 21 does not slide, the friction between the hanger 21 and the slide rail 31 can also fix the lifting assembly on the slide rail 31, thereby preventing the oil tank 30 from falling during the aerial lifting process.

[0038] In some embodiments, a specific implementation of the clamping assembly 12 can be as follows: Figure 4 See the structure shown. Figure 4 The clamping assembly 12 includes a protective cover 121, a clamping motor 122, a lead screw 123 and two claws 124. The protective cover 121 is fixedly connected to the bottom of the support leg 11, and a strip-shaped through groove 127 is provided at the bottom of the protective cover 121; the clamping motor 122 is arranged in the protective cover 121, and the output shaft of the clamping motor 122 is fixedly connected to a first bevel gear 125; the lead screw 123 is rotatably connected in the protective cover 121, and the axial direction of the lead screw 123 is parallel to the horizontal direction. A second bevel gear 126 meshing with the first bevel gear 125 is provided in the middle of the lead screw 123, and the threads at both ends of the lead screw 123 are rotated in opposite directions; the two claws 124 are respectively matched with the two end portions of the lead screw 123, and the two claws 124 both extend out of the through groove 127 and slide with the through groove 127.

[0039] After the clamping motor 122 is started, the clamping motor 122 drives the first bevel gear 125 to rotate, the first bevel gear 125 drives the second bevel gear 126 to rotate, the second bevel gear 126 drives the lead screw 123 to rotate, and the two claws 124 screwed on both ends of the lead screw 123 move along the axial direction of the lead screw 123. By controlling the forward and reverse rotation of the output shaft of the clamping motor 122, the opposite movement or back-to-back movement of the two claws 124 can be achieved.

[0040] The clamping motor 122 can be synchronously controlled by the control system of the drone 10 , which is easy to operate and quick to respond.

[0041] In some embodiments, an improved implementation of the above-mentioned fuel tank 30 can be adopted as follows Figure 6 See the structure shown. Figure 6 The top of the oil tank 30 is provided with an exhaust valve 50, which includes a first valve body 51, a second valve body 52, an oil baffle plate 53 and a float 54. The outer periphery of the first valve body 51 is provided with a first oil inlet 511, and the bottom is provided with an oil outlet 512; the second valve body 52 is provided in the middle of the first valve body 51, and the side wall of the second valve body 52 is spaced from the side wall of the first valve body 51. The top of the second valve body 52 is provided with an exhaust port 522, and the side wall is provided with a second oil inlet 521. The oil inlet 521 is higher than the first oil inlet 511, and a third oil inlet 523 is provided at the bottom of the second valve body 52; the oil baffle plate 53 is connected between the side wall of the second valve body 52 and the side wall of the first valve body 51, and the oil baffle plate 53 is located directly above the first oil inlet 511; the float 54 is slidably connected to the second valve body 52 in the up and down directions, and the float 54 has a first state lower than the second oil inlet 521, and a second state higher than the second oil inlet 521 and blocking the exhaust port 522.

[0042] It is easy to imagine that the oil baffle plate 53 is only provided for a section in the circumferential direction of the second valve body 52 , and the length of the oil baffle plate 53 is equal to the length of the first oil inlet 511 .

[0043] When a small amount of oil enters the space between the first valve body 51 and the second valve body 52 through the first oil inlet 511, the oil is blocked by the oil baffle plate 53, and the oil flows downward and flows back to the oil tank 30 from the oil outlet 512, while the gas passes through the space on both sides of the oil baffle plate 53 and enters the second valve body 52 from the second oil inlet 521 and is discharged from the exhaust port 522 on the top. When the oil in the oil tank 30 is full, the oil level gradually rises, and the float 54 floats upward under the buoyancy of the oil until the exhaust port 522 is blocked to prevent oil leakage.

[0044] In some embodiments, an improved embodiment of the exhaust valve 50 can be implemented as follows: Figure 6 See the structure shown. Figure 6The top of the float 54 is provided with an extension rod 55, the top of the extension rod 55 is fixedly connected with an indicator light 56 ​​and a conductive ring 57 conductively connected to the indicator light 56, and the top of the second valve body 52 is also provided with a power supply ring 58 located at the periphery of the exhaust port 522. When the float 54 is in the second state, the conductive ring 57 is conductively connected to the power supply ring 58, and the indicator light 56 ​​is on. When the float 54 floats upward to the second state, the height of the conductive ring 57 is equal to the height of the power supply ring 58. At this time, the conductive ring 57 is powered on, and the indicator light 56 ​​is on, indicating that the oil level in the oil tank 30 is full at this time, so that personnel can immediately judge the oil level in the oil tank 30 through the indicator light 56.

[0045] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
