Description

Technical Field

[0001] The present invention relates to the technical field of unmanned submarines, and in particular to an unmanned submarine for transporting medical supplies. Background Art

[0002] At present, long-distance maritime transportation of medical supplies such as medicinal materials and blood mainly relies on ship containers or drones. Among them, although ship transportation can carry large quantities of goods, the deck containers are easily exposed to direct sunlight, causing internal temperature fluctuations (such as the surface seawater temperature in summer reaching above 20°C), and need to rely on high-energy active refrigeration systems to maintain a cool environment for medicinal materials (13-18°C) or refrigerated blood (3-5°C), which is costly and unstable. Although drone transportation can avoid some temperature risks, its endurance and load capacity are limited, the single transportation volume is small, and the economy of missions over 100 nautical miles is significantly reduced. Therefore, some logistics companies use underwater transportation.

[0003] In the existing underwater transportation technology, some unmanned submarines have tried to carry cargo in pressure-resistant cabins, and use the negative correlation between seawater depth and temperature (such as about 10°C at a depth of 50 meters and below 5°C above 100 meters) to passively lower the ambient temperature in the cabin.

[0004] However, such designs are mostly targeted at industrial goods, and are not optimized for the needs of medical supplies. For example, the devices used to fix medical supplies are generally tied directly with static straps, which makes it easy for bulk transported medical supplies (such as boxed medicines and blood) to loosen or be damaged in a bumpy environment. These shortcomings seriously restrict the efficiency and safety of underwater medical transportation. Summary of the invention

[0005] In view of the deficiencies raised by the above-mentioned background technology, the present invention provides an unmanned submarine for transporting medical supplies.

[0006] The present invention adopts the following technical solution: An unmanned submarine for transporting medical supplies includes: A shuttle body is provided with a accommodating cabin, a hatch is provided on the shuttle body, a positioning module and a propulsion module are arranged in the shuttle body, and the propulsion module drives the shuttle body to move along the positioning terminal path; A conveyor is arranged in the accommodating cabin, wherein the conveyor belt of the conveyor is used to place medical supplies, the conveying direction of the conveyor belt is consistent with the length direction of the shuttle body, and one end of the conveyor belt is located under the hatch; A fixing device is arranged on the conveyor, and the fixing device includes a clamping plate. The clamping plates are arranged on both sides of the conveyor, and the two clamping plates move parallel to the middle of the conveyor to clamp and fix the medical materials on the conveyor belt.

[0007] In a possible implementation, a hatch is disposed on the hatch, and the hatch is flipped relative to the hatch to open or close the hatch.

[0008] In a possible implementation, the fixing device also includes a lifting rod and a first transmission rod, a crossbeam is fixed on one side of the hatch in the accommodating cabin, both sides of the crossbeam are connected to the lifting rod, a shoulder is arranged at the upper end of the crossbeam, and a first elastic member is arranged between the shoulder and the crossbeam, the elastic force of the first elastic member forms a thrust to push the lifting rod upward; the two clamping plates and the two lifting rods are connected through the first transmission rod, the two ends of the first transmission rod are respectively pivotally connected to the lower end of the lifting rod and the connecting plate, and the upper end of the first transmission rod is close to the middle of the width direction of the conveyor relative to the lower end of the first transmission rod.

[0011] In a possible implementation, the shuttle body is provided with a downwardly recessed step on the upper edge of the hatch, and a sealing ring is fixed on a side of the hatch facing the accommodating cabin. When the hatch is flipped to cover the hatch, the hatch is adapted to be embedded in the step, and the sealing ring is pressed against the step.

[0012] In one possible implementation, the unmanned submarine also includes a lifting device arranged in the accommodating compartment and located under the hatch, the lifting device includes a lifting plate and a guide plate, the lifting plate is raised and lowered relative to the hatch under the hatch, and when the lifting plate moves downward, the lifting plate is connected to the end face of the conveyor, the guide plate is embedded in the lifting plate, and one side of the lifting plate's opening is hinged to the guide plate, so that the guide plate can be flipped upward to be inclined relative to the lifting plate.

[0013] In a possible implementation, the bottom surface of the guide plate is slidably connected to the telescopic plate, and the telescopic plate is bent on one side close to the outside of the guide plate to form a leaning portion. The side of the lifting plate opposite to the opening protrudes upward to form a blocking surface. After the telescopic plate is pulled out of the guide plate, the leaning portion is hooked on the blocking surface, so that the guide plate and the telescopic plate are tilted relative to the lifting plate.

When the conveyor belt runs to the point where the limit plate is located on the bottom surface of the conveyor, the limit plate pushes the other end of the rocker arm to swing, so as to pull the slide to move through one end of the rocker arm, and drive the lifting plate to move to the baffle, and then push the lifting plate to move upward along the baffle to the hatch.

[0015] In a possible implementation, a plurality of support brackets are arranged and fixed in the shuttle body at the lower part of the accommodating cabin, the conveyor is fixed on the support brackets, a mounting rod is fixed between two adjacent support brackets near the hatch position, a rotating shaft is fixed on the mounting rod, the rocker arm adapter rotates on the rotating shaft, and a torsion spring is arranged outside the rotating shaft, one end of the torsion spring is connected to the mounting rod, and the other end of the torsion spring is connected to the rocker arm, so that the torsional force formed by the torsion spring drives the end of the rocker arm connected to the second transmission rod to swing away from the hatch, so as to drive the slide and the lifting plate to move toward the direction of the conveyor, and the lifting plate descends to connect with the conveyor belt.

[0016] From the above description of the structure of the present invention, it can be seen that compared with the prior art, the present invention has the following advantages: the shuttle body of the present invention realizes the opening and sealing of the hatch through a hinged hatch.

[0032] In order to make the objectives, technical solutions and advantages of the present application clearer, the present application will be further described in detail below in conjunction with the accompanying drawings.

[0033] In the following, the terms "first", "second", etc. are used for descriptive purposes only and are not to be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Thus, a feature defined as "first", "second", etc. may explicitly or implicitly include one or more of the feature. In the description of this application, unless otherwise specified, "plurality" means two or more.

[0034] In addition, in the present application, directional terms such as "upper" and "lower" are defined relative to the orientation of the components in the drawings. It should be understood that these directional terms are relative concepts. They are used for relative description and clarification, and they may change accordingly according to the changes in the orientation of the components in the drawings.

[0035] The present invention discloses an unmanned submarine for transporting medical supplies. Figures 1 to 3 As shown, the unmanned submarine includes a shuttle 1, a conveyor 2, a fixing device and a lifting device. A storage compartment 101 is arranged in the shuttle 1, a hatch 102 is arranged on the shuttle 1, and the shuttle 1 is hinged with a hatch door 11 at the hatch 102. The conveyor 2, the fixing device and the lifting device are all arranged in the storage compartment 101. The shuttle 1 is equipped with a dedicated air-conditioning system 14 for adjusting the ambient temperature in the storage compartment 101 to meet the constant temperature transportation requirements of different medical supplies. When transporting blood products, the air-conditioning system 14 can stably control the temperature in the cabin within the standard temperature range of 3 to 5°C for blood storage; when transporting conventional medicines, it automatically switches to a normal temperature storage mode of 13 to 18°C. This intelligent temperature control solution effectively ensures the biological activity and quality stability of different medical supplies during the underwater transportation process by accurately maintaining a suitable storage environment for different medical supplies.

[0036] The shuttle body 1 is also equipped with a cruise system and a vehicle, wherein the navigation controller of the cruise system is used to establish a wireless communication connection with a server on the ground. The vehicle includes a main propeller and a steering mechanism. During cruising, the server sends corresponding cruise control instructions to the navigation controller of the cruise system according to the satellite positioning data, travel direction, surrounding obstacle information and planned cruise path of the vehicle. The navigation controller controls the operation of the main propeller and the steering mechanism according to the received cruise control instructions, thereby driving the underwater vehicle toward the cruise destination to realize the transportation of medical supplies.

[0037] As shown in the accompanying drawings, a hatch 11 is arranged on the hatch 102, and the hatch 11 can be turned relative to the hatch 102 by a hinge connection, so that the hatch 102 is opened or closed. In addition, the shuttle body 1 is also screwed with a sealing bolt 12 on one side of the hatch 102, and the hatch 11 is provided with a connecting hole. When the hatch 11 is turned over to close the hatch 102, the sealing bolt 12 passes through the connecting hole and is screwed with the shuttle body 1 to tighten the sealing bolt 12, so that the hatch 11 remains fixed to close the hatch 102. Further, the shuttle body 1 is provided with a downwardly concave step on the upper edge of the hatch 102, and the hatch 11 is fixed with a sealing ring on one side facing the inside of the accommodating cabin 101. When the hatch 11 is turned over to cover the hatch 102, the hatch 11 is adapted to be embedded in the step, and the sealing ring is pressed on the step. Through this structure, the inside of the accommodating cabin 101 is completely sealed after the hatch 102 is closed.

[0038] As shown in Figures 4 and 6, the conveyor belt 21 of the conveyor 2 is used to place medical supplies. A plurality of support brackets 22 are arranged and fixed below the storage compartment 101 in the shuttle body 1, and the conveyor 2 is fixed on the support brackets 22, so as to form a structure placed flat in the storage compartment 101, and the conveying direction of the upper surface of the conveyor belt 21 is consistent with the length direction of the shuttle body 1, and one end of the conveyor belt 21 is located under the hatch 102. Medical drugs can be placed one by one on the conveyor belt 21 from the hatch 102, and move inward one by one as the upper surface of the conveyor belt 21 moves into the storage compartment 101, forming a placement method in which medical drugs are arranged and placed in the storage compartment 101. In addition, a plurality of limit plates are arranged at equal intervals on the surface of the conveyor belt 21, and the space between two adjacent limit plates is the position for placing a row of medical drugs, so that the medical drugs can be placed in an orderly manner.

[0039] The fixing device is arranged on the conveyor 2, as shown in the attached Figures 3 to 5As shown, the fixing device includes a clamping plate 31, and the clamping plates 31 are arranged on both sides of the conveyor 2, and the two clamping plates 31 move parallel to the middle of the conveyor 2 to clamp and fix the medical supplies on the conveyor belt 21. The clamping plate 31 can be arranged in such a way that the support members 32 are fixed on both sides of the support frame 22, and the support members 32 are fixed to a side facing the middle of the conveyor 2 to extend parallel to the guide rods 321, and the clamping plates 31 are provided with guide holes. The guide holes of the two clamping plates 31 are adapted to pass through the guide rods 321 on both sides of the conveyor 2 in a one-to-one correspondence, so that the two clamping plates 31 can move parallel to the middle of the conveyor 2 along the guide rods 321, thereby clamping and fixing the medical supplies on the conveyor belt 21. Furthermore, a buffer plate 33 is provided on one side of the clamping plate 31 facing the middle of the conveyor 2, and the buffer plate 33 presses the medical supplies on the conveyor belt 21, and a second elastic member 331 is connected between the buffer plate 33 and the clamping plate 31, and the elastic force of the second elastic member 331 forms a thrust to push the buffer plate 33 toward the middle of the conveyor 2. The second elastic member 331 is used to form a buffer to press against the medical drugs, so as to prevent the clamping force of the two clamping plates 31 from being too tight and thus damaging the medical drugs.

[0040] Continue to refer to the attached Figure 3 and 5 The fixing device also includes a lifting rod 34 and a first transmission rod 35. A crossbeam 13 is fixed on one side of the hatch 11 in the accommodation cabin 101. Both sides of the crossbeam 13 are connected to the lifting rod 34. The lifting rod 34 passes through the crossbeam 13 and is restricted to vertical lifting relative to the crossbeam 13. The lifting rod 34 is provided with a shoulder 341 at the upper end of the crossbeam 13, and a first elastic member 342 is provided between the shoulder 341 and the crossbeam 13. The elastic force of the first elastic member 342 forms a thrust to push the lifting rod 34 upward. A connecting plate extending toward the middle of the conveyor belt 21 is fixed above the clamping plate 31. The two clamping plates 31 and the lifting rod 34 are connected by the first transmission rod 35. The two ends of the first transmission rod 35 are respectively pivotally connected to the lower end of the lifting rod 34 and the connecting plate, and the upper end of the first transmission rod 35 is close to the middle of the width direction of the conveyor 2 relative to the lower end of the first transmission rod 35. Preferably, a connecting plate extending toward the middle of the conveyor belt 21 can be fixed above the clamp plate 31, and the two clamp plates 31 are pivotally connected through the connecting plate and the first transmission rod 35 to ensure that the upper end of the first transmission rod 35 is close to the middle of the width direction of the conveyor 2 relative to the lower end of the first transmission rod 35, so that after the lifting rod 34 is lowered, the clamp plate 31 can be pushed to move toward the middle of the conveyor belt 21 through the first transmission rod 35.

[0041] Specifically, after the medical drugs are placed in the storage compartment 101, the hatch 11 is flipped down to close the hatch 102, and the hatch 11 presses down the two lifting rods 34 to descend, so that the two first transmission rods 35 swing and drive the two clamps 31 to move synchronously to the middle of the conveyor 2, so that the medical drugs are automatically clamped and fixed while the hatch 11 is closed, so as to avoid the medical materials from shaking and colliding during transportation and being damaged. When the medical drugs in the storage compartment 101 need to be taken out, the hatch 11 is opened, and the lifting rods 34 automatically rise under the elastic force of the first elastic member 342, so that the two first transmission rods 35 swing and drive the two clamps 31 to move synchronously to both sides of the conveyor 2, so that the medical drugs are automatically released while the hatch 11 is opened, so as to facilitate the removal of medical materials.

[0042] As attached Figures 4 to 8 As shown, the lifting device is located under the hatch 102, and the lifting device includes a lifting plate 41 and a guide plate 42. The lifting plate 41 is correspondingly raised and lowered relative to the hatch 102, and the opening of the lifting plate 41 faces the conveyor belt 21. When the lifting plate 41 moves downward, the lifting plate 41 is connected to the end surface of the conveyor 2, so that the conveyor belt 21 can transport medical supplies to the lifting plate 41. The guide plate 42 is embedded in the lifting plate 41, and one side of the opening of the lifting plate 41 and the guide plate 42 are hinged by connecting hinges or inserting pins, so that the guide plate 42 can be flipped relative to the lifting plate 41 to be parallel or inclined. Refer to the attached Fig.12 The middle of the bottom surface of the lifting plate 41 is hollowed out to form a clearance opening, and the top surface of the lifting plate 41 is fixed with support plates 411 on both sides of the clearance opening. The support plates 411 extend to the range of the clearance opening, so that the guide plate 42 can be placed flat on the support plate 411 after being flipped over to be embedded in the clearance opening, so that the guide plate 42 can be parallel to the lifting plate 41, that is, the guide plate 42 is integrated to form the bottom surface of the lifting plate 41, which is convenient for the conveyor belt 21 to transport the medical drugs into the lifting plate 41.

[0043] After the guide plate 42 is turned upward to be inclined relative to the lifting plate 41, the medical drugs can slide down along the guide plate 42 to the conveyor belt 21 when being lowered from the hatch 102. Fig.13 The bottom surface of the guide plate 42 is slidably connected to the telescopic plate 421, and the connection method can be that sliding grooves are provided on both sides of the bottom surface of the guide plate 42, and the two sides of the telescopic plate 421 are respectively adapted to be embedded in the two sliding grooves and slide relative to the guide plate 42, and the telescopic plate 421 is bent on a side close to the outside of the guide plate 42 to form a leaning portion 422, and the side of the lifting plate 41 relative to the opening protrudes upward to form a blocking surface 412. When the guide plate 42 needs to be tilted, the guide plate 42 is flipped up and the telescopic plate 421 is pulled out, and then the leaning portion 422 is hooked on the blocking surface 412, so that the guide plate 42 and the telescopic plate 421 can be tilted relative to the lifting plate 41.

[0044] As attached Figure 7 ,9 As shown in Figure 11, the lifting device also includes a slide 43, a swing rod 45 and a second transmission rod 46. Both ends of the slide 43 and the lifting plate 41 are connected by a connecting rod 44 to form a parallelogram structure, so that the lifting plate 41 always remains parallel to the slide 43. A vertical baffle 47 is fixed on one side of the corresponding conveyor 2 in the storage cabin 101, and the baffle 47 is used to block the lifting plate 41. When the slide 43 moves toward the hatch 102, the lifting plate 41 is pushed by the connecting rod 44 to move accordingly, and when the lifting plate 41 is pushed to the baffle 47, the force of the continued movement of the slide 43 drives the connecting rod 44 to lift up, so as to move the lifting plate 41 upward along the baffle 47 to the hatch 102, forming an action process of automatically lifting the medical drugs to the hatch 102, without reaching into the storage cabin 101 to take the medical drugs out, it can be seen that the removal process is more convenient. Furthermore, a guide wheel 413 is fixed on the side of the lifting plate 41 facing away from the conveyor 2. After the lifting plate 41 is pushed to the baffle 47 by the carriage 43, the guide wheel 413 presses against the baffle 47 to make the lifting plate 41 rise upward along the guide plate. The structure of the guide wheel 413 can reduce the friction force of the lifting plate 41 and guide the lifting plate to rise along the baffle 47. In addition, guide wheels 413 can be provided on both sides of the plate opening of the lifting plate, and a vertical baffle (not shown in the drawings) can be fixed on the side of the hatch 102 of the shuttle body 1 close to the conveyor 2 to limit the guide wheel 413 of the lifting plate 41 at one end of the plate opening 102, so as to assist the lifting plate 41 to only be lifted vertically after moving under the hatch 102.

[0045] The middle of the swing rod 45 is limited to rotate in the middle below the conveyor 2. The specific connection method can be as shown in the attached Figure 8 and 10 As shown, a mounting rod 48 is fixed between two adjacent support brackets 22 near the hatch 102, a rotating shaft 481 is fixed on the mounting rod 48, the middle of the swing rod 45 is adapted to fit the rotating shaft 481, and then a bolt is fixed above the rotating shaft 481 to limit the swing rod 45 to rotate only along the rotating shaft 481. The two ends of the second transmission rod 46 are respectively pivotally connected to one end of the swing rod 45 and the slide 43, so that the swing rod 45 can swing and the slide 43 can be pulled or pushed by the second transmission rod 46 to move. When the conveyor belt 21 moves until the limit plate is located at the bottom of the conveyor 2, the limit plate on the surface of the conveyor belt 21 pushes the other end of the swing rod 45 to swing, so that one end of the swing rod 45 swings accordingly, and the slide 43 is pulled or pushed by the second transmission rod 46 to move relative to the hatch 102 and the conveyor 2, and the lifting plate 41 is driven to move accordingly.

[0046] Continue to refer to the attached Figure 8 and 10, the rotating shaft 481 is covered with a torsion spring 49, one end of the torsion spring 49 is connected to the mounting rod 48, and the other end of the torsion spring 49 is connected to the swing rod 45. The torsion spring 49 forms a torsion elastic force to drive the end of the swing rod 45 connected to the second transmission rod 46 to swing away from the hatch 102, so as to drive the slide 43 and the lifting plate 41 to move in the direction of the conveyor 2, and the lifting plate 41 is lowered to engage with the conveyor belt 21, that is, the lifting plate 41 can automatically reset downward to align with the conveyor belt 21 again after lifting the medical drugs to the hatch 102, so that the conveyor 2 can transport the medical drugs to the lifting plate 41 again. In addition, the conveyor 2 is also fixed with a stop pin 451. When the swing rod 45 swings to drive the slide 43 and the lifting plate 41 to move close to the conveyor belt 21 of the conveyor 2, the stop pin 451 blocks the swing rod 45 to prevent the lifting plate 41 from moving to abut against the conveyor belt 21.

[0047] Combined with Figure 4 , 14 and 15, the working mode of the present invention is as follows: After the hatch 11 is opened, the two clamping plates 31 automatically move outwards on both sides of the conveyor 2 to loosen the medical supplies, and then the conveyor belt 21 of the conveyor 2 is started to drive the medical supplies to move toward the hatch 102; After the conveyor belt 21 conveys a box of medical supplies to the lifting plate 41, the limit plate in front of the medical supplies moves downward to the bottom surface of the conveyor 2 and pushes the swing rod 45 to swing, so that the swing rod 45 pulls the slide 43 to move through the second transmission rod 46, thereby driving the lifting plate 41 to move to the baffle 47, and then the lifting plate 41 is pushed by the connecting rod 44 to move upward along the baffle 47 to the hatch 102, forming an action process of automatically lifting the medical drugs to the hatch 102; Afterwards, the limit plate that pushes the rocker arm 45 continues to move until it leaves the rocker arm 45, and the torsion spring 49 forms a torsional elastic force that drives the end of the rocker arm 45 connected to the second transmission rod 46 to swing away from the hatch 102, thereby resetting and pulling the slide 43 to reset, so that the lifting plate 41 is reset again to align and connect with the conveyor belt 21.

[0048] In summary, the present invention is equipped with a conveyor in the storage compartment of the shuttle body 1 for placing medical supplies inward in sequence, and the shuttle body 1 is equipped with an air conditioning system 14 for ensuring the constant temperature transportation requirements of different medical supplies in the storage compartment 101. The shuttle body 1 realizes the opening and sealing of the hatch 102 through the hinged hatch 11. When the hatch 11 is closed, the linkage lifting rod 34 is pressed down to drive the clamping plate 31 to clamp the medical supplies on the conveyor belt 21 to avoid damage caused by shaking and collision during transportation of the medical supplies. A limit plate is provided on the surface of the conveyor 2 to arrange the items in a regular manner. The lifting device is linked with the slide 43 through the swing rod 45. When the conveyor belt 21 runs to the limit plate triggering the swing rod 45 to swing, the slide is driven to move, thereby driving the lifting plate 41 to rise along the baffle 47 to the hatch 102 to complete the automatic lifting of the medical supplies, which is convenient for taking out. Then, the torsion spring 49 is reset to make the lifting plate 41 drop to align with the conveyor belt 21, which is convenient for conveying the medical supplies to the lifting plate 41 again. It can be seen that the present invention can realize the synchronous control of the opening and closing of the cabin door 11 and the tightening and loosening of the clamp, as well as the automatic transportation and lifting of medical supplies out of the cabin.

[0049] The above is only a specific implementation of the present invention, but the design concept of the present invention is not limited thereto. Any non-substantial changes to the present invention using this concept shall be deemed as an infringement of the protection scope of the present invention.
