Description

Technical Field

[0001] The invention relates to the technical field of ships, and in particular to an unmanned remote-controlled rescue boat. Background Art

[0002] An unmanned remote-controlled rescue boat is a rescue boat that can be remotely controlled. It is equipped with a variety of sensors and cameras, which can monitor the surrounding environment in real time and transmit video and location information back to the control center. Rescuers use these data to understand the on-site situation and guide rescue operations. Modern rescue boats are usually equipped with high-precision navigation systems, which enable them to move accurately in complex waters. They can quickly find and approach people in distress through remote control and autonomous navigation technology. However, existing rescue boats still have certain shortcomings, that is, when they find people in distress, if the number of people in distress is relatively large, the rescue boat itself is not large in size and has limited carrying capacity, so it is impossible to rescue multiple people in distress at the same time. Even if it can pass the situation to the control center to send additional rescue boats, this process takes a certain amount of time. During this period, it is very likely that the people in distress will become physically exhausted due to lack of support points, resulting in more urgent and dangerous situations. If the people in distress rely on the rescue boat for support, it is very likely that the rescue boat will not have enough buoyancy and will sink. Summary of the invention

[0003] The object of the present invention is to provide an unmanned remote-controlled rescue boat to solve the problems raised in the above-mentioned background technology.

[0004] To achieve the above object, the present invention provides the following technical solutions: An unmanned remote-controlled rescue boat comprises a hull, an electric push-pull rod is fixedly installed at the rear end of the hull, and a load-bearing fixing rod is also fixedly arranged on the hull below the electric push-pull rod; The hull on both sides of the load-bearing fixing rod is symmetrically provided with mounting through holes, and the electric push-pull rod is fixedly provided with a first buoyancy-increasing mechanism, which can increase the buoyancy of the hull and prevent the hull from sinking; The first buoyancy-increasing mechanism is connected to a movable life-saving mechanism, and the first buoyancy-increasing mechanism drives the movable life-saving mechanism to rotate and unfold; Support mechanisms are fixedly arranged on the upper ends of both sides of the hull, and the support mechanisms support the movable lifesaving mechanism.

The driving bearing plate is fixedly installed on the electric push-pull rod, and first movable push rods are symmetrically hinged at both ends of the driving bearing plate; The other end of the first movable push rod is hinged with a first buoyancy plate. The first buoyancy plate is inserted into the moving mating channel; Closed bearing plates are respectively and fixedly arranged on both sides of the first buoyancy plate. A closed insertion ring is fixedly arranged on the closed bearing plate. When the closed insertion ring seals the moving mating channel, it is inserted into the closed insertion groove.

[0008] Preferably, a connection mating plate is fixedly arranged on the closed bearing plate of the first buoyancy plate inside the hull. The connection mating plate is hinged with the other end of the first movable push rod; Auxiliary support plates are respectively and fixedly arranged at both ends of the closed bearing plate of the first buoyancy plate inside the hull. Auxiliary support bars are fixedly arranged on the auxiliary support plates. The auxiliary support bars are inserted into the support channel.

[0009] Preferably, a mating rack is further fixedly arranged at one end of the closed bearing plate of the first buoyancy plate inside the hull close to the electric push-pull rod. A mating connection convex frame is fixedly arranged on the closed bearing plate below the mating rack; A second movable push rod is hinged on the mating connection convex frame. The other end of the second movable push rod is hinged with a moving push bar plate.

[0010] Preferably, a bearing limit through hole is formed in the moving push bar plate. A bearing fixing rod is inserted into the bearing limit through hole; Mounting bearing frames are respectively and fixedly arranged at both ends of the moving push bar plate. The mounting bearing frames are hinged with the other end of the second movable push rod; A bearing bending frame is further fixedly arranged on the moving push bar plate above the mounting bearing frame. A driving rack is fixedly arranged on the bearing bending frame. The driving rack is connected with the movable life-saving mechanism.

[0011] Preferably, the movable life-saving mechanism is a life-saving board rack, and a driving gear is fixedly arranged at the upper end of the life-saving board rack, and the driving gear meshes with a driving rack; An installation rotating column is fixedly arranged at the lower end of the life-saving board rack, the installation rotating column is inserted into a rotating bearing hole, and a limiting and mating bottom block is fixedly arranged at the lower end of the installation rotating column.

[0012] Preferably, the first buoyancy increasing mechanism comprises a second buoyancy board and an auxiliary buoyancy board. The second buoyancy board is installed at the rear end of the hull, a receiving and mating cavity is arranged on the second buoyancy board, and a bearing rotating shaft is also fixedly arranged on the second buoyancy board; A mechanical seal is sleeved on the bearing rotating shaft, the mechanical seal is installed in an installation through hole, and a mating gear is fixedly arranged at one end of the bearing rotating shaft away from the second buoyancy board, and the mating gear meshes with a mating rack; An installation channel is formed in the mating gear, and the installation channel penetrates through the bearing rotating shaft and the receiving and mating cavity.

[0014] Compared with the prior art, the beneficial effects of the present invention are as follows: The structure of the present invention is reasonably arranged and has strong functionality, and has the following advantages: 1. When the rescue boat finds a large number of victims, it can stay at the scene to provide strong support for the victims, so that the victims are in a relatively safe state waiting for rescue. That is, life-saving racks are respectively arranged on both sides of the hull, and they are in an unfolded state during use, so that more support points can be provided for multiple victims to hold and provide support for them, waiting for the arrival of rescue. When not in use, they are stored on both sides of the hull, making the overall volume of the hull smaller, facilitating its passage through some narrow areas. Moreover, it can increase the buoyancy of the hull and avoid the phenomenon of the hull sinking due to too many victims.

[0015] 2. When providing a support point for the victim, the electric push rod drives the driving bearing plate to move. In this way, under the action of the driving bearing plate, the first buoyancy plate will protrude outside the hull. When the first buoyancy plate contacts the water, it can increase the buoyancy of the hull. At the same time, the cooperation between the closed bearing plate and the mating ring platform can prevent water from entering the hull. Moreover, when the first buoyancy plate moves, it will also drive the moving push bar plate to move. Under the action of the moving push bar plate, the life-saving rack will be driven to rotate to an unfolded state, facilitating the provision of more support points for the victim. Meanwhile, the auxiliary support bar can play an auxiliary supporting role for the unfolded life-saving rack to ensure its firmness.

[0016] 3. In addition, when the first buoyancy plate moves, it will also drive the second buoyancy plate to rotate from a vertical state to a horizontal state. In this way, when the second buoyancy plate contacts the water surface, it can also increase the buoyancy of the hull. Moreover, when the moving push bar plate moves, it will also drive the auxiliary buoyancy plate to move, making part of it protrude outside the second buoyancy plate. In this way, the auxiliary buoyancy plate can also provide buoyancy support, fully ensuring the buoyancy of the hull and increasing its supporting capacity. Description of the Drawings

A closed insertion slot 19 is provided on the mating ring platform 18. The closed insertion slot 19 cooperates with the first buoyancy increasing mechanism to realize the sealing at the moving mating channel 17. In addition, the first buoyancy increasing mechanism is located inside the hull 1 in the non-working state.

[0032] As Figure 1 , Figure 2 and Figure 5 As shown, the first buoyancy increasing mechanism includes a driving bearing plate 2, a first buoyancy plate 3 and a moving push bar plate 4. The driving bearing plate 2 is fixedly installed on the electric push rod 11. First movable push rods 21 are symmetrically hinged at both ends of the driving bearing plate 2. The other end of the first movable push rod 21 is hinged to the first buoyancy plate 3. The first buoyancy plate 3 is inserted into the moving mating channel 17. Sealing bearing plates 31 are respectively fixedly arranged on both sides of the first buoyancy plate 3. A closed insertion ring 32 is fixedly arranged on the sealing bearing plate 31. When the closed insertion ring 32 seals the moving mating channel 17, it is inserted into the closed insertion slot 19.

When the first buoyancy plate 3 is outside the hull 1, the closed insertion ring 32 inside the hull 1 cooperates with the closed insertion slot 19 inside the hull 1.

[0033] As Figure 1 As shown, a connecting mating plate 33 is fixedly arranged on the sealing bearing plate 31 of the first buoyancy plate 3 inside the hull 1.

[0034] As Figure 7As shown in the figure, a mating rack 36 is fixedly arranged at one end of the enclosed bearing plate 31 inside the hull 1 on the first buoyancy plate 3, which is close to the electric push rod 11. A mating connection convex frame 37 is fixedly arranged on the enclosed bearing plate 31 below the mating rack 36. A second movable push rod 38 is hinged on the mating connection convex frame 37. The other end of the second movable push rod 38 is hinged with a movable push top strip plate 4.

[0035] As Figure 1 , Figure 2 , Figure 7 and Figure 8 shown in the figure, a bearing limit through hole 41 is formed on the movable push top strip plate 4. A bearing fixing rod 12 is inserted into the bearing limit through hole 41. Mounting bearing frames 42 are respectively fixedly arranged at both ends of the movable push top strip plate 4. The mounting bearing frames 42 are hinged with the other end of the second movable push rod 38. A bearing bending frame 43 is also fixedly arranged on the movable push top strip plate 4 above the mounting bearing frames 42. A driving rack 44 is fixedly arranged on the bearing bending frame 43. The driving rack 44 is connected with a movable life-saving mechanism.

[0036] As Figure 1 and Figure 8 shown in the figure, the movable life-saving mechanism is a life-saving board frame 5. A driving gear 51 is fixedly arranged at the upper end of the life-saving board frame 5. The driving gear 51 is meshed with the driving rack 44. When the life-saving board frame 5 is in a non-working state, it is stored on both sides of the hull 1, that is, the life-saving board frame 5 is parallel to the side surface of the hull 1.

[0037] A mounting rotating column 52 is fixedly arranged at the lower end of the life-saving board frame 5. The mounting rotating column 52 is inserted into the rotating bearing hole 15. A limit mating bottom block 53 is fixedly arranged at the lower end of the mounting rotating column 52. In addition, the limit mating bottom block 53 is located below the supporting extension platform 14. When the life-saving board frame 5 is in an unfolded state, it is perpendicular to the side surface of the hull 1. At this time, the auxiliary support strip 35 can further support it.

[0038] As Figure 1 , Figure 2 , Figure 6 and Figure 10 shown in the figure, the first buoyancy increasing mechanism includes a second buoyancy plate 6 and an auxiliary buoyancy plate 66. The second buoyancy plate 6 is installed at the rear end of the hull 1. A storage mating cavity 61 is arranged on the second buoyancy plate 6. A bearing rotating shaft 62 is also fixedly arranged on the second buoyancy plate 6. A mechanical seal 63 is sleeved on the bearing rotating shaft 62. The mechanical seal 63 is installed in the installation through hole 13. A mating gear 64 is fixedly arranged at the end of the bearing rotating shaft 62 far from the second buoyancy plate 6. The mating gear 64 is meshed with the mating rack 36. And the mating gear 64 is located below the mating rack 36.

[0039] The mating gear 64 is provided with an installation channel 65, and the installation channel 65 penetrates through the bearing rotating shaft 62 and the accommodation mating cavity 61.

[0040] As Figure 6 and Figure 10 shown, an auxiliary buoyancy plate 66 is inserted into the accommodation mating cavity 61. A channel mating rod 67 is fixedly arranged on the auxiliary buoyancy plate 66. The channel mating rod 67 is inserted into the installation channel 65. A reset connection spring 68 is sleeved on the channel mating rod 67. A mating support block 69 is also fixedly arranged on the channel mating rod 67. The mating support block 69 is in contact with the moving push bar plate 4. The two ends of the reset connection spring 68 are respectively fixed on the mating gear 64 and the mating support block 69. In addition, the second buoyancy plate 6 and the auxiliary buoyancy plate 66 are in a vertical state in the non-working state.

[0041] When the rescue boat discovers the victims and the number of victims is large and they cannot be rescued immediately in real time, at this time, the staff can remotely control the electric push rod 11 to drive the driving and bearing plate 2 to move towards the front end of the hull 1. With the movement of the driving and bearing plate 2, under the action of the first movable push rod 21, the first buoyancy plate 3 will be pushed to move, so that the first buoyancy plate 3 protrudes outside the hull 1. At the same time, the closed plugging ring 32 of the first buoyancy plate 3 inside the hull 1 will be plugged into the closed plugging groove 19 inside the hull 1 to realize the sealing at the mobile cooperation channel 17. And the first buoyancy plate 3 outside the hull 1 can provide greater buoyancy for the hull 1 and improve the bearing capacity of the hull 1. In addition, when the first buoyancy plate 3 moves towards the outside of the hull 1, under the action of the second movable push rod 38, it will drive the movable push and top strip plate 4 to move towards the tail of the hull 1. With the movement of the movable push and top strip plate 4, under the action of the driving rack 44, it will drive the driving gear 51 to rotate, so as to drive the life-saving board rack 5 to rotate to its unfolded state. When the life-saving board rack 5 is in the storage state, the volume of the whole hull 1 is smaller, which is convenient for it to move in a narrow environment. After the life-saving board rack 5 is in the unfolded state, it can provide more support points for the victims, which is convenient for more victims to hold the life-saving board rack 5 for support until the rescue arrives. And when the first buoyancy plate 3 moves towards the outside of the hull 1, the auxiliary support strip 35 will also move with it. In this way, when the life-saving board rack 5 is in the unfolded state, the auxiliary support strip 35 can extend its support to ensure the firmness and stability of the support of the life-saving board rack 5 for the victims. In addition, when the first buoyancy plate 3 moves, under the action of the cooperation rack 36, it will also drive the cooperation gear 64 to rotate, so that the second buoyancy plate 6 rotates to the horizontal state. At the same time, when the movable push and top strip plate 4 moves, it will also push the cooperation support block 69 to move, so that part of the auxiliary buoyancy plate 66 protrudes outside the storage cooperation cavity 61. In this way, under the action of the second buoyancy plate 6 and the auxiliary buoyancy plate 66, the buoyancy of the hull 1 can be further increased and its bearing capacity can be increased. In this way, when the hull 1 needs to support more victims, under the combined action of the first buoyancy plate 3, the second buoyancy plate 6 and the auxiliary buoyancy plate 66, the bearing capacity of the hull 1 can be greatly improved to ensure the stability of the hull 1.

[0042] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention.
