Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of rescue devices, and particularly relates to a rescue fuel transportation device. BACKGROUND

[0002] Natural disasters (such as earthquakes, floods, mudslides, etc.) often bring devastating damage, such as severe road damage, and heavy losses of power supply, oil supply and other infrastructure. In this case, the disaster area urgently needs to restore power supply, ensure vehicle mobility and the normal work of rescue machines to carry out emergency rescue and post-disaster reconstruction. Fuel, as a key energy source for the operation of these devices, is particularly important for its supply.

[0003] In the case of insufficient road resources (road damage) or high ground transportation costs (mountainous environment), air transportation of fuel is a more reliable solution. The existing technology mainly uses helicopters to air-drop fuel supply such as oil bags and oil barrels. However, this method cannot guarantee the accuracy of the drop location of the oil tank or oil bag. Since the disaster area often has complex terrain, a slight deviation in the drop location can cause the oil bag or oil barrel to fall in a difficult-to-access place, causing great inconvenience in subsequent retrieval and use. In addition, helicopters require professional pilots to operate, which is costly and risky. SUMMARY

[0004] The present application provides a rescue fuel transportation device, which aims to solve the technical problems of the existing method of using helicopters to air-drop oil bags or oil tanks, which cannot guarantee the accuracy of the drop location, and the subsequent retrieval and use are inconvenient.

After use, the reset mechanism drives the blocking block 42 to move downwards until the second inclined taper surface 421 is in abutment with the first inclined taper surface 411.

[0052] The use process of the rescue fuel transportation device provided by the embodiment is as follows: after the oil tank 30 is connected with the lifting frame 20, the lifting frame 20 is clamped by the clamping assembly 12 at the bottom of the unmanned aerial vehicle 10, the oil tank 30 can be transported by flying of the unmanned aerial vehicle 10, in the transportation process, the position information of the oil tank 30 can be transmitted to the sensing module on the unmanned aerial vehicle 10 by the recording module 34, and the unmanned aerial vehicle 10 transmits the position information of the oil tank 30 to the personnel remotely controlling the unmanned aerial vehicle 10 and the personnel receiving the rescue materials through the communication module, when the oil tank 30 reaches the specified position, the clamping assembly 12 on the unmanned aerial vehicle 10 releases the oil tank 30 and flies away, the personnel receiving the materials finds the oil tank 30 according to the position information of the oil tank 30, and the oil quantity and specification in the oil tank 30 are determined according to the detection module 33 and the recording module 34 on the oil tank 30, so that the use is convenient, when oil is needed to be taken from the oil tank 30, the blocking block 42 can be pushed upward, at this time, the blocking block 42 slides upward and separates from the first inclined taper surface 411 and the second inclined taper surface 421, the oil in the oil tank 30 can flow out from the interval between the first inclined taper surface 411 and the second inclined taper surface 421, and after use, the reset mechanism automatically resets the blocking block 42, the first inclined taper surface 411 and the second inclined taper surface 421 abut, and the oil continues to flow out.

[0053] Compared with the prior art, the rescue fuel transportation device adopts the unmanned aerial vehicle 10 to transport the oil tank 30, which is convenient for remote control, does not need professional pilots to operate, has lower training and use cost, and correspondingly lower risk; the clamping assembly 12 is arranged on the unmanned aerial vehicle 10, which facilitates the oil tank 30 to be grabbed and released, and the oil tank 30 can be released after flying to a specified point, so that the position of the oil tank 30 is more accurate compared with air dropping; the detection module and the recording module 34 on the oil tank 30 can accurately record the oil quantity in the oil tank 30, the type of fuel, the position of the oil tank 30 and other information, so that the receiver can quickly obtain the information of the oil tank 30, and thus find the most suitable oil tank 30 to use; the quick connector 40 is arranged on the oil tank 30, which facilitates quick oil taking, and the use is more convenient and the operation is simpler.

[0054] Specifically, the top of the oil tank 30 is also provided with a conventional oil inlet 32, and the oil tank 30 cover is screwed on the conventional oil inlet 32, when the oil tank 30 is not installed on the unmanned aerial vehicle 10, if the oil tank 30 is to be refueled, the oil tank 30 can be inverted and refueled through the quick connector 40, if the oil tank 30 is installed on the unmanned aerial vehicle 10, the oil tank 30 is not convenient for inversion operation, the oil tank 30 cover can be unscrewed, and the oil tank 30 can be refueled through the conventional oil inlet 32.

[0055] In some embodiments, one specific implementation of the reset mechanism can adopt a structure as shown in Figure 5 . Figure 5The upper end of the shell 41 is internally provided with a guide disc 44, the guide disc 44 is provided with a central hole and a plurality of through holes 45 which are uniformly distributed around the central hole and used for allowing the oil to pass through; the blocking block 42 is fixedly connected with a guide rod 46 which is in sliding fit with the central hole; the reset mechanism is a reset spring 43 which is sleeved on the guide rod 46 and has two ends which are respectively in abutment with the guide disc 44 and the blocking block 42.

[0056] When the blocking block 42 is pushed, the blocking block 42 is in abutment with the reset spring 43, so that the reset spring 43 is compressed, at this time, the second inclined taper surface 421 around the blocking block 42 is separated from the first inclined taper surface 411, and the oil in the oil tank 30 can flow out through the through holes 45, the interval between the first inclined taper surface 411 and the second inclined taper surface 421 in sequence, when the blocking block 42 is released, the reset spring 43 rebounds and pushes the blocking block 42 to move downward until the second inclined taper surface 421 is in abutment with the first inclined taper surface 411.

[0057] The structure can realize the automatic reset of the blocking block 42, after the blocking block 42 is no longer pushed, the blocking block 42 can quickly return to the original position, the oil is timely blocked, and the waste of the oil is avoided.

The reset spring 43 is sleeved on the outer periphery of the guide rod 46, so that the extension and contraction process of the reset spring 43 is guided, and the end of the reset spring 43 which is close to the blocking block 42 is inserted into the sink groove 422, so that the positioning between the reset spring 43 and the blocking block 42 is realized.

[0059] In some embodiments, one improved implementation of the above-mentioned blocking block 42 can adopt the structure as shown in Figure 5 Referring to Figure 5 , the second inclined taper surface 421 is provided with a recessed annular groove, the annular groove is provided with a first sealing ring 47, and the first sealing ring 47 is used for abutting against the first inclined taper surface 411. By arranging the first sealing ring 47 on the second inclined taper surface 421, the sealing effect between the first inclined taper surface 411 and the second inclined taper surface 421 can be improved, and the waste of energy caused by oil leakage is avoided.

[0060] As a deformation, the recessed annular groove and the first sealing ring 47 can also be arranged on the first inclined taper surface 411, one of the first inclined taper surface 411 and the second inclined taper surface 421 can be selected, or both of them can be arranged.

[0061] In some embodiments, one improved implementation of the above-mentioned shell 41 can adopt the structure as shown in Figure 5 Referring toFigure 5 The lower end of the shell 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 with the quick connector 40, the external interface can be plugged into the plug-in groove on the shell 41, and the structure corresponding to the blocking block 42 on the external interface can automatically abut against 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, thereby avoiding oil leakage.

[0062] In some embodiments, an improved embodiment of the above-mentioned shell 41 can adopt the structure as shown in Figure 5 . Referring to Figure 2 to 3 , the outer periphery of the shell 41 is further provided with a limiting disc 49, which is spaced below the lifting frame 20. By providing the limiting disc 49 on the shell 41, the plugging depth when the external interface is connected with the quick connector 40 can be limited, and the use is more convenient.

[0063] In some embodiments, a specific embodiment of the above-mentioned lifting frame 20 can adopt the structure as shown in Figures 2 to 3 . Referring to Figure 4 , the oil tank 30 is provided with two horizontally arranged slide rails 31 on opposite sides, and the lifting frame 20 includes two lifting assemblies, each of which is connected with one of the two slide rails 31 in one-to-one correspondence. Each lifting assembly includes at least two lifting rods 21 and a connecting rod 22, and the plurality of lifting rods 21 are slidably connected with the same slide rail 31. The connecting rod 22 is detachably connected to the top ends of the plurality of lifting rods 21, and the connecting rod 22 is connected with the clamping assembly 12. The lifting rod 21 is slidably adjusted on the slide rail 31, which facilitates the adjustment of the position of the lifting rod 21 on the slide rail 31. After the lifting rod 21 is installed, the connecting rod 22 is connected with the plurality of lifting rods 21, and the assembly of one lifting assembly can be completed. The structure is convenient for assembly and disassembly, and after the oil tank 30 is transported to the position, the lifting rod 21 and the connecting rod 22 can be disassembled and used as a rescue tool.

[0064] Optionally, the lifting rod 21 and the connecting rod 22 can be connected by clamping, plugging, threaded connection or the like.

[0065] It should be noted that the cross-sectional shape of the slide rail 31 is special, and the corresponding sliding hole of the lifting rod 21 is also special. The lifting rod 21 can be slid on the slide rail 31 by pushing with great force, but when the lifting rod 21 does not slide, the friction between the lifting rod 21 and the slide rail 31 can also fix the lifting assembly on the slide rail 31, thereby avoiding the falling of the oil tank 30 during the process of hoisting in the air.

[0066] In some embodiments, a specific embodiment of the above-mentioned clamping assembly 12 can adopt the structure as shown in Figure 4 . Referring to Figure 6The clamping assembly 12 includes a protective cover 121, a clamping motor 122, a screw 123 and two claws 124. The protective cover 121 is fixed to the bottom of the support leg 11, and the bottom of the protective cover 121 is provided with a strip-shaped through groove 127; the clamping motor 122 is arranged in the protective cover 121, and the output shaft of the clamping motor 122 is fixed with a first bevel gear 125; the screw 123 is rotatably connected to the protective cover 121, and the axial direction of the screw 123 is parallel to the horizontal direction. The middle part of the screw 123 is provided with a second bevel gear 126 that meshes with the first bevel gear 125, and the threads at both ends of the screw 123 rotate in opposite directions; the two claws 124 are respectively matched with the two end parts of the screw 123, and the two claws 124 extend out of the through groove 127 and slide with the through groove 127.

[0067] 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 screw 123 to rotate, and the two claws 124 screwed on both ends of the screw 123 move along the axial direction of the screw 123. By controlling the forward and reverse rotation of the output shaft of the clamping motor 122, the two claws 124 can achieve opposite movement or back movement.

[0068] The clamping motor 122 can be synchronously controlled by the control system of the drone 10, which is easy to operate and has a quick response.

[0069] In some embodiments, an improved embodiment of the fuel tank 30 may be as follows: Figure 6 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 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 second 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 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 53 is located directly above the first oil inlet 511; the float 54 is connected to the second valve body 52 in a sliding manner 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.

[0070] 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 .

[0071] 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 53, and the oil flows downward from the oil outlet 512 back to the oil tank 30, while the gas passes through the space on both sides of the oil baffle 53, enters the second valve body 52 through the second oil inlet 521, and is discharged from the top exhaust port 522. When the oil tank 30 is full of oil, the oil level gradually rises, and the float 54 floats upward under the buoyancy of the oil, until it blocks the exhaust port 522, preventing the oil from leaking out.

[0072] In some embodiments, an improved embodiment of the above-mentioned exhaust valve 50 can adopt the structure as shown in Figure 6 . Referring to ​ , the top end of the float 54 is provided with an extension rod 55, the top end of the extension rod 55 is fixedly connected with an indicator light 56, and a conductive ring 57 is in conductive connection with the indicator light 56. The second valve body 52 is further provided with a power supply ring 58 located on the outer periphery of the exhaust port 522. When the float 54 is in the second state, the conductive ring 57 is in conductive connection with 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 which time the conductive ring 57 is connected to electricity, and the indicator light 56 is on, indicating that the oil tank 30 is full of oil, which facilitates personnel to immediately determine the oil quantity in the oil tank 30 through the indicator light 56.

[0073] The above only describes the preferred embodiments of the present application and is not intended to limit the present application. Any modification, equivalent replacement and improvement made within the spirit and principle of the present application shall be included in the protection scope of the present application.
