Description

Technical Field

[0001] The present invention relates to the technical field of deployment and recovery, and particularly to a device for deploying and recovering a water surface observer and a ship. Background Art

[0002] With the rapid development of fields such as ocean resource development, maritime search and rescue, and scientific research, the demand for deploying and recovering water surface observers is increasing day by day. However, the existing deployment and recovery technologies are difficult to meet the actual requirements under severe sea conditions and high-speed navigation conditions. Currently, the traditional devices for deploying and recovering water surface observers are mainly of the hanging type. The hanging type equipment requires multiple operators to cooperate. In a complex sea condition environment, there will be severe coupled motion between the mother ship and the suspended observer, which not only seriously threatens the safety of the operators, but also may cause collisions and damages between the observer and the hull. During the recovery process, relying on manual operation to complete rope fixing and dragging is not only inefficient but also has great potential safety hazards. Summary of the Invention

[0003] Based on this, it is necessary to provide a device for deploying and recovering a water surface observer and a ship to address the problem that in a complex sea condition environment, collisions between the mother ship and the suspended observer may cause danger and damage in the existing deployment and recovery devices.

[0004] In a first aspect, the present invention provides a device for deploying and recovering a water surface observer, which is arranged on the ship deck and is used for deploying and recovering the water surface observer on the sea surface. The device for deploying and recovering a water surface observer includes: a moving platform for fixing the water surface observer, a tipping gantry device for lifting the moving platform, and a moving mechanism for horizontally moving the tipping gantry device; the moving mechanism includes two linear guides and two sliding plates; the two sliding plates slide on the two linear guides respectively.

[0005] Among them, the tipping gantry device includes: a support frame, at least one lifting mechanism, at least one clutch mechanism, and at least one tipping oil cylinder. The support frame includes two columns; the bottoms of the two columns are respectively hinged on the two sliding plates. The lifting mechanism includes a driving structure and a connecting rod. The driving structure is installed on the column and is used for driving the connecting rod to move along the length direction of the column. At least two corresponding jacks are provided on both the moving platform and the connecting rod. The clutch mechanism includes a telescopic cylinder and a pin corresponding to the jack. The pin is connected to the piston rod of the telescopic cylinder and is used for driving through the telescopic cylinder to connect or disconnect the connecting rod and the moving platform. One end of the tipping oil cylinder is hinged on the sliding plate, and the other end is hinged on the column, and is used for driving the column to rotate on the sliding plate and controlling the column to maintain a horizontal or vertical state.

[0006] In a second aspect, the present invention further provides a ship for deploying and recovering a water surface observer, which includes the device for deploying and recovering a water surface observer in the first aspect.

[0007] The beneficial effects of the present invention are as follows:

[0008] 1. Through the settings of the moving platform, the flipping gantry device and the moving mechanism, the water surface observer is fixed on the moving platform, and the moving platform is rigidly connected to the flipping gantry device, so that the water surface observer can remain stable during the deployment and recovery processes and will not shake randomly, thus preventing the water surface observer from colliding with the hull and causing damage and danger.

[0009] 2. The flipping gantry device in the present invention can be connected to and separated from the moving platform. At the same time, the flipping gantry device can be flipped from the working state when it is vertical to the storage state when it is horizontal, avoiding the drawbacks caused by its excessive height and facilitating the utilization of the space position on the deck.

[0025] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the technical field to which the present invention belongs.

The term "or / and" used herein includes any and all combinations of one or more of the related listed items.

[0026] Please refer to Figure 1, this embodiment provides a device for deploying and retrieving a water surface observer, which includes: a moving platform 1 for fixing the water surface observer 4, a tipping gantry device 2 for lifting the moving platform 1, and a moving mechanism 3 for horizontally moving the tipping gantry device 2. The moving mechanism 3 moves the tipping gantry device 2 to the outer edge of the ship's deck, and then the tipping gantry device 2 drives the moving platform 1 to lift and lower to complete the deployment and retrieval of the water surface observer 4. Compared with the existing devices, this device for deploying and retrieving the water surface observer 4 is rigidly connected during the process of deploying and retrieving the water surface detector, thus avoiding the water surface observer 4 from shaking and colliding with the hull. In addition, another feature of the present invention is that the designed tipping gantry device 2 can be flipped and folded, greatly reducing its height. The reason is that if the height of the ship's deck is relatively high, in order to avoid the disadvantages brought by the existing hanging type technology, the length of the rigid member extending from the deck to the sea surface must also be relatively long at this time. In this way, when the moving platform 1 rises to the deck, the rigid member connecting the moving platform 1 also rises accordingly, which is bound to cause the height of the rigid member to be much higher than the deck. And the excessive height will also bring some disadvantages, such as affecting its stability on windy days, and may collide when passing through bridges and culverts. Based on this, the present invention provides a device for deploying and retrieving a water surface observer that can not only solve the problem of easy collision in the prior art, but also avoid the disadvantages of excessive height of the rigid member. Next, the structures and functions of the three major components constituting the device for deploying and retrieving the water surface observer will be introduced one by one.

[0027] 1. The function of the moving platform 1 is to fix the water surface observer 4 and send it into the sea. The moving platform 1 in this embodiment includes: a grid plate 11, two ear seats 12, and two gripping devices 13. The grid plate 11 serves as a platform for placing the water surface observer 4, and is designed with lightweight while ensuring strength. The two ear seats 12 are fixedly connected to the same end of the grid plate 11 and are located on both sides respectively. Two jacks are provided on each ear seat 12. The two gripping devices 13 jointly clamp and fix a water surface detector to make it more secure on the grid plate 11. Such as Figure 2As shown in the figure, taking a grasping device 13 as an example, it includes two bases 131, two grippers 132, and two cylinders 133. The two bases 131 are relatively fixed on the grille plate 11. The two grippers 132 are respectively hinged to the two bases 131. The gripper 132 is arc-shaped. The arc-shaped concave surfaces of the two grippers 132 are arranged oppositely to increase the contact area. At the same time, a buffer rubber 134 is arranged on the concave surface of the gripper 132 to protect the outer surface of the water surface detector. One end of the two cylinders 133 is respectively hinged to the two bases 131, and the other end is respectively hinged to the arc-shaped convex surfaces of the two grippers 132. By the telescopic movement of the cylinders 133, the two grippers 132 are driven to rotate on the bases 131, so as to realize the opening and closing of the two grippers 132, thereby fixing or releasing the water surface detector. In another embodiment, the moving platform 1 further includes two slide rails and four driving members. The two grasping devices 13 are respectively slidably connected to the two slide rails. Specifically, the two bases 131 of the grasping device 13 both slide on the slide rails, and at the same time, each driving member is connected to one base 131. The driving member can be an electric cylinder, an oil cylinder or a cylinder 133, which is used to drive the two bases 131 to approach or move away from each other on the slide rails, and to adapt to fix water surface detectors of more specifications by adjusting the distance between the two bases 131.

[0028] II. The flipping gantry device 2 is a key design part of the present invention. With reference to Figure 3 and Figure 4 , the flipping gantry device 2 includes a support frame, two lifting mechanisms, two clutch mechanisms, and two flipping oil cylinders 211. Specifically, the support frame includes two columns 21, two upper supports 22, two lower supports 23, and an upper cross beam 24. The two upper supports 22 are respectively fixed at one end of the two columns 21. The two lower supports 23 are respectively fixed at the other end of the two columns 21 and are hinged to the moving mechanism 3. The upper cross beam 24 is fixed between the two upper supports 22, thus forming a stable gantry structure. The two lifting mechanisms are respectively arranged on the two columns 21, and each of them includes a driving structure and a connecting rod 25 (equivalent to the above-mentioned rigid member). In this embodiment, with reference to Figure 3 and Figure 5, the drive structure includes a motor 26, a lead screw 27, a guide rod 28, and a moving block 29. The motor 26 is fixed on the upper support 22. The column 21 is arranged as hollow. The lead screw 27 is arranged in parallel inside the column 21, with one end connected to the output shaft of the motor 26 and the other end rotatably connected to the lower support 23. Similarly, the guide rod 28 is also arranged inside the column 21, but both ends of the guide rod 28 are respectively fixed to the upper support 22 and the lower support 23, playing a role in limiting the moving block 29. The moving block 29 is connected to the lead screw 27 through a lead screw nut and sleeved on the guide rod 28 through a linear bearing. By driving the lead screw 27 to rotate through the motor 26, the moving block 29 is further driven to move along the length direction of the column 21. Grooves communicating with the inside are opened on one side of the two columns 21 close to each other. One end of the moving block 29 extends into the groove. The connecting rod 25 is located outside the column 21, and one end of the connecting rod 25 is connected to the moving block 29 at the groove, so that the connecting rod 25 can move along with the movement of the moving block 29. Two jacks corresponding to the jacks on the ear seat 12 are opened at the end of the connecting rod 25 away from the moving block 29.

[0029] The clutch mechanism utilizes the jacks on the ear seat 12 and the connecting rod 25 to connect or disconnect the connecting rod 25 and the moving platform 1. To ensure sufficient connection strength, two clutch mechanisms are respectively arranged at the two ear seats 12. Taking one clutch mechanism as an example, it includes two telescopic cylinders 210 and two pins. Both telescopic cylinders 210 are fixed on the ear seat 12. The pins are connected to the piston rods of the telescopic cylinders 210 and correspond to the jacks. By controlling the movement of the piston rods of the telescopic cylinders 210 to drive the pins to extend into the jacks on the ear seat 12 and the connecting rod 25, the connection between the connecting rod 25 and the moving platform 1 is completed. Disengaging the pins from the jacks on the connecting rod 25 can disconnect the connecting rod 25 and the moving platform 1.

[0030] There are also two tilting oil cylinders 211. One end of the two tilting oil cylinders 211 is hinged to the moving mechanism 3, and the other ends are respectively hinged to the upper ends of the two columns 21 or the upper support 22. Through the telescopic drive of the tilting oil cylinders 211, the entire support frame rotates on the moving mechanism 3 and keeps the support frame in a horizontal or vertical state.

[0031] III. The moving mechanism 3 is fixed on the ship deck, and it drives the tilting gantry device 2 to move horizontally, so that it can extend to the outer edge of the deck, thereby lifting and lowering the moving platform 1. In this embodiment, with reference to Figure 1 and Figure 6, the moving mechanism 3 includes two linear guides 31, two sliding plates 32, a fixed rod 33, a winch 34 and a fixed pulley 35. The two linear guides 31 are fixedly parallel on the deck and face the outer edge of the deck, that is, the side facing the moving platform 1. The two sliding plates 32 are respectively slidably connected to the two linear guides 31. The two lower supports 23 are respectively hinged to the two sliding plates 32 through two T-shaped seats 311. The translation of the entire tipping gantry device 2 is driven by the sliding of the sliding plate 32 on the linear guide 31. It is worth mentioning that the hinge point between the lower support 23 and the sliding plate 32 is located at one end of the sliding plate 32 close to the moving platform 1. The hinge point between the tipping oil cylinder 211 and the sliding plate 32 is located at a relatively middle position of the sliding plate 32, so that the tipping gantry device 2 is flipped and folded to the side away from the moving platform 1. The fixed rod 33 is connected between the two sliding plates 32 and is close to the middle position of the sliding plate 32, so as to form a whole to enhance the structural strength. An upper pulling ear 36 and a lower pulling ear 37 are fixed on the fixed rod 33. The winch 34 and the fixed pulley 35 are both fixed on the deck and are respectively located on both sides of the fixed rod 33. Of course, the winch 34 needs to be arranged on the side far from the outer edge of the deck for easy installation and use. A rope is wound on the winch 34. One end of the rope is connected to the upper pulling ear 36, and the other end is wound around the fixed pulley 35 and then connected to the lower pulling ear 37. In this way, the reciprocating movement of the sliding plate 32 on the linear guide 31 can be driven by the forward and reverse rotation of the winch 34. Further, in order to avoid interference when the tipping gantry device 2 is folded. Avoidance grooves 38 for placing the tipping oil cylinder 211 are provided on both sliding plates 32. The lower end of the tipping oil cylinder 211 is hinged in the avoidance groove 38 to prevent the tipping oil cylinder 211 from being clamped between the column 21 and the sliding plate 32 when the column 21 is laid down. Similarly, front pads 39 and rear pads 310 are fixed on both sliding plates 32. The front pad 39 is used to support the lower support 23 in the vertical state to prevent the hinge of the lower support 23 from protruding and affecting the stability of the entire column 21. The rear pad 310 is used to support the upper support 22 in the horizontal state so that both ends of the column 21 are supported when folded.

[0032] The working principle of the present invention is as follows: When performing the laying task, the gripper device 13 first fixes the water surface observer 4 on the grating plate 11. The tipping oil cylinder 211 drives the tipping gantry device 2 to rotate from the horizontal to the vertical state. Subsequently, the telescopic cylinder 210 controls the insertion pin to extend, so that the connecting rod 25 and the moving platform 1 are connected as a whole for subsequent actions. The winch 34 drives the sliding plate 32 to move forward. When moving to a suitable position, the motor 26 drives the lead screw 27 to rotate, driving the moving platform 1 to move downward. As Figure 7 shown, the moving platform 1 descends below the deck plane. After reaching a suitable position on the sea surface, the gripper 132 opens to release the water surface observer 4.

[0033] When performing the recovery task, the gripper 132 opens significantly. After the remotely controlled surface observer 4 moves to an appropriate area on the moving platform 1, the gripper 132 closes and fixes it. Then, the motor 26 drives the lead screw 27 to rotate, driving the moving platform 1 to move upward. After reaching the corresponding position above the ship's deck, the winch 34 drives the slide plate 32 to retract backward. When the moving platform 1 retracts onto the deck, the telescopic cylinder 210 drives the pin to retract, separating the connecting rod 25 from the moving platform 1. Subsequently, the tilting oil cylinder 211 shortens, driving the tilting gantry device 2 to tilt and retract until it folds onto the slide plate 32, and its state is as shown in Figure 8 shown. The folded tilting gantry device 2 not only saves space on the deck but also avoids the possible collision risk in its vertical state.

[0034] In another embodiment, a ship for deploying and recovering a surface observer is also proposed, which includes the surface observer deploying and recovering device in the above embodiment. The surface observer 4 is deployed and recovered on the sea surface through this deploying and recovering device.

[0035] The technical features of the above-described embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope recorded in this specification.

[0036] The above-described embodiments only represent several implementation manners of the present invention. Their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the invention patent. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several modifications and improvements can still be made, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the present invention patent should be subject to the appended claims.
