Description

Technical Field

[0001] This invention relates to the field of diving equipment, and more particularly to a device for preventing the swaying of a diving bell. Background Technology

[0002] A diving bell is a piece of equipment used in diving operations, typically for underwater exploration, rescue, and construction. During diving operations, a diving bell lowering device is used to lower the diving bell to the work location below the water surface. During the lowering process, especially during the entry and exit of the diving bell and its return to the mother ship, the diving bell is subjected to significant impacts. Therefore, a sway-stabilizing device is needed to maintain the stability of the diving bell and prevent damage or accidents caused by violent shaking. Currently, sway-stabilizing devices generally use dampers to absorb sway energy and reduce the amplitude of sway, or adjust the distance and connection structure between the diving bell and the lowering device to maintain stability during lowering. While these devices can reduce the amplitude of sway to some extent, their effectiveness is not ideal, and the diving bell is prone to colliding with the mother ship or the lowering device, leading to damage to both.

[0003] Therefore, it is necessary to design a diving bell hoisting anti-sway device that can effectively stop the swaying during the process of lowering the diving bell from the mother ship to the water surface. Summary of the Invention

[0004] In order to overcome the shortcomings of existing anti-sway devices, such as insufficient reduction of sway amplitude, poor anti-sway effect, and easy occurrence of diving bell collision and damage to the launching equipment, this invention provides a diving bell launching anti-sway device that can effectively stop the sway during the process of launching the diving bell from the mother ship to the water surface.

[0005] A diving bell hoisting and anti-sway device includes a base plate, a support frame, hydraulic cylinders, a fixed shaft, a hoisting and anti-sway mechanism, and a lowering guide mechanism. The support frame is rotatably connected to the upper side of the base plate. The hydraulic cylinders are rotatably connected between the support frame and the left and right sides of the front part of the base plate. The fixed shaft is connected to the left and right sides of the upper part of the support frame. The hoisting and anti-sway mechanism for stabilizing the diving bell is provided on the fixed shaft. The lower part of the support frame is provided with the lowering guide mechanism for smoothly retrieving the diving bell.

[0006] Optionally, the lifting anti-sway mechanism includes a rotating shaft, a mounting frame, an anti-sway frame, a rotating anti-sway component, a torsion spring, an electric push rod, a locking pin, and an alignment plate. The rotating shaft is rotatably connected between the fixed shafts. The mounting frame is connected to the middle of the rotating shaft. The anti-sway frame is connected to the lower side of the mounting frame. The rotating anti-sway component is rotatably connected to the lower side of the anti-sway frame at even intervals. The torsion spring is connected between the rotating anti-sway component and the anti-sway frame. The electric push rod is connected to the upper left and right sides of the mounting frame. The telescopic end of the electric push rod is connected to the locking pin. The alignment plate is connected to each fixed shaft. The locking pin engages with the alignment plate on the same side.

[0007] Optionally, the lowering guide mechanism includes a fixed base, a cylinder, a connecting frame, and a guide roller. The lower left and right sides of the support frame are each connected to two sets of fixed bases, each set consisting of two fixed bases, one in front and one in back. The cylinder is rotatably connected to each fixed base. The connecting frame is rotatably connected between the telescopic ends of the cylinders on the same side. The guide roller is rotatably connected to the middle of each connecting frame.

[0008] Optionally, it also includes a sway limiting mechanism, which includes a fixed disk, a rotating disk, a sliding pin, and a first spring. The fixed disk is connected to the upper left and right sides of the support frame, and the rotating disk is connected to the left and right sides of the rotating shaft. The rotating disk is located in the middle of an adjacent fixed disk. The sliding pin is slidably connected to the rotating disk at even intervals around its circumference. The sliding pin is engaged with the adjacent fixed disk, and the first spring is connected between the sliding pin and the adjacent rotating disk.

[0009] Optionally, it also includes a placement stabilizing mechanism, which includes a placement seat, a locking member, and a second spring. The placement seat is connected to the middle of the base plate, and a plurality of second springs are connected to the upper side of the placement seat. The locking member is connected to the upper side of each of the second springs.

[0010] Optionally, it also includes an inflatable reinforcement mechanism, which includes an airbag and a connecting pipe. The airbag is connected to each of the rotation stoppers, and the connecting pipe is connected to the upper side of each airbag.

[0011] Optionally, it also includes a cable guiding mechanism, which includes a limiting wheel, a first guide wheel, and a second guide wheel. The left and right sides of the mounting frame are rotatably connected to two symmetrically positioned limiting wheels. The left and right sides of the anti-sway frame are rotatably connected to two first guide wheels. The lower left and right sides of the anti-sway frame are rotatably connected to the second guide wheel.

[0012] Optionally, the base plate has drainage holes.

[0013] The present invention has the following advantages: 1. The diving bell of the present invention will contact the rotating anti-sway component, thereby limiting and fixing the diving bell by the swing of the rotating anti-sway component. The anti-sway frame can limit the counterweight of the diving bell, so that the diving bell is always perpendicular to the horizontal plane. At the same time, it can also control the operation of the electric push rod, thereby driving the locking pin to move outward and engage with the alignment plate, so that the anti-sway frame cannot rotate, thereby achieving anti-sway of the diving bell and preventing the diving bell from swinging during the process of being lowered from the mother ship to the water surface, which would cause the diving bell to collide with the lifting equipment and cause damage.

[0014] 2. During the lowering process of this invention, the cylinder can also be driven to operate, thereby bringing the connecting frame and the guide roller closer together to limit and stabilize the diving bell, thus enabling the diving bell to be retrieved smoothly.

[0015] 3. The oscillation of the anti-sway frame of the present invention will cause the rotating shaft to rotate, which in turn will drive the rotating disk to rotate. At this time, due to the centrifugal force, the sliding pin will be centrifugally thrown out and engage with the fixed disk. The first spring is stretched, and the engagement of the sliding pin with the fixed disk will restrict the rotation of the rotating disk, thereby effectively restricting the swaying of the diving bell and making the diving bell stable.

[0016] 4. In this invention, the diving bell is placed on the locking component, which causes the diving bell below to move downward. The second spring is compressed, which causes the locking components around it that are not pressing down to limit the diving bell, thereby allowing the diving bell to be placed stably and facilitating the docking of the hoisting equipment with the diving bell.

[0017] 5. The connecting pipe of this invention can be connected to an external inflation device. After the diving bell pushes the rotating anti-swaying component to swing, the inflation device can be controlled to inject air into the airbag through the connecting pipe, so that the airbag can clamp the diving bell, thereby further limiting and stabilizing the diving bell.

[0018] 6. The hoisting rope of the hoisting device of the present invention can contact the limiting wheel, then pass through the first guide wheel and contact the second guide wheel, and then connect to the diving bell, thereby avoiding wear of the hoisting rope and thus preventing accidents during the hoisting of the diving bell.

Detailed Implementation

[0030] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings. It is hereby declared that the directional terms such as up, down, left, right, front, back, inside, and outside used in this text are based solely on the accompanying drawings and are not intended to specifically limit the invention.

[0031] A diving bell suspension anti-sway device, such as Figures 1-5As shown, the device includes a base plate 1, a support frame 2, a hydraulic cylinder 3, a fixed shaft 4, a lifting and anti-sway mechanism 5, and a lowering guide mechanism 6. The base plate 1 has drainage holes. The support frame 2 is rotatably connected to the upper side of the base plate 1. The hydraulic cylinder 3 is rotatably connected between the support frame 2 and the left and right sides of the front part of the base plate 1. The fixed shaft 4 is connected to the upper left and right sides of the support frame 2. The lifting and anti-sway mechanism 5 is provided on the fixed shaft 4. The lifting and anti-sway mechanism 5 is used to stop the diving bell from swaying. The lower part of the support frame 2 is provided with the lowering guide mechanism 6. The lowering guide mechanism 6 is used to smoothly retrieve the diving bell.

[0032] like Figure 1 , Figure 3 and Figure 4 As shown, the lifting and anti-sway mechanism 5 includes a rotating shaft 50, a mounting frame 51, an anti-sway frame 52, a rotating anti-sway component 53, a torsion spring 54, an electric push rod 55, a locking pin 56, and an alignment plate 57. The rotating shaft 50 is rotatably connected to the fixed shafts 4. The mounting frame 51 is connected to the middle of the rotating shaft 50. The anti-sway frame 52 is connected to the lower side of the mounting frame 51. The rotating anti-sway component 53 is rotatably connected to the lower side of the anti-sway frame 52 at even intervals. The torsion spring 54 is connected between the rotating anti-sway component 53 and the anti-sway frame 52. The electric push rod 55 is connected to the upper left and right sides of the mounting frame 51. The telescopic end of the electric push rod 55 is connected to the locking pin 56. The alignment plate 57 is connected to the fixed shafts 4. The locking pin 56 engages with the alignment plate 57 on the same side.

[0033] like Figure 1 and Figure 5 As shown, the lowering guide mechanism 6 includes a fixed base 60, a cylinder 61, a connecting frame 62, and a guide roller 63. The lower left and right sides of the support frame 2 are connected to two sets of fixed bases 60, each set consisting of two fixed bases 60, one in front and one in back. The cylinder 61 is rotatably connected to each fixed base 60. The connecting frame 62 is rotatably connected between the telescopic ends of the cylinders 61 on the same side. The guide roller 63 is rotatably connected to the middle of the connecting frame 62.

[0034] This device can be used when hoisting a diving bell. First, place the diving bell on the base plate 1. Then, pass the hoisting rope through the mounting frame 51 and the anti-sway frame 52 and connect it to the diving bell. The hoisting equipment can then be controlled to lift the diving bell. During the lifting process, the diving bell will contact the rotating anti-sway component 53, causing it to swing. The torsion spring 54 deforms, thus fixing the diving bell in place. The hydraulic cylinder 3 can then be operated, causing the support frame 2 to rotate and swing, moving the diving bell to the surface. Simultaneously, the anti-sway frame 52 provides a counterweight to limit the diving bell, ensuring it remains perpendicular to the water surface. The electric push rod 55 can also be controlled, causing the locking pin 56 to move outward and engage with the alignment plate 57, preventing the anti-sway frame 52 from rotating, thus achieving the desired lifting effect for the diving bell. The submersible bell is stabilized to prevent it from swaying during its descent from the mother ship to the surface, which could lead to collisions and damage to the descent equipment. Afterward, the submersible bell can be lowered, at which point it disengages from the rotating stabilizing element 53. The torsion spring 54 then returns to its original position, causing the rotating stabilizing element 53 to rotate in the opposite direction and reset. When the submersible bell needs to be retrieved, it is lifted from the water. The bell then pushes the rotating stabilizing element 53 to swing again, causing it to reposition itself against the stabilizing frame 52. The hydraulic cylinder 3 then drives the support frame 2 to reset. Under the counterweight of the stabilizing frame 52, the submersible bell is brought back to a vertical position, allowing it to be lowered. During lowering, the cylinder 61 can also be activated, causing the connecting frame 62 and the guide roller 63 to move closer together to stabilize and limit the submersible bell, ensuring a smooth retrieval.

[0035] like Figure 1 , Figure 6 and Figure 7 As shown, it also includes a sway limiting mechanism 7, which includes a fixed disk 70, a rotating disk 71, a sliding pin 72, and a first spring 73. The fixed disk 70 is connected to the upper left and right sides of the support frame 2, and the rotating disk 71 is connected to the left and right sides of the rotating shaft 50. The rotating disk 71 is located in the middle of the adjacent fixed disk 70. The sliding pin 72 is slidably connected to the rotating disk 71 at even intervals around the circumference. The sliding pin 72 is engaged with the adjacent fixed disk 70, and the first spring 73 is connected between the sliding pin 72 and the adjacent rotating disk 71.

[0036] When the sea is rough, the counterweight of the anti-sway frame 52 is insufficient to stabilize the diving bell. In this case, the swing of the anti-sway frame 52 will cause the rotating shaft 50 to rotate, which in turn will drive the rotating disk 71 to rotate. Due to centrifugal force, the sliding pin 72 will be centrifugally thrown out and engage with the fixed disk 70. The first spring 73 will be stretched, and the engagement of the sliding pin 72 with the fixed disk 70 will restrict the rotation of the rotating disk 71, thereby effectively limiting the swaying of the diving bell and stabilizing it.

[0037] like Figure 1 , Figure 8 and Figure 9 As shown, it also includes a placement stabilization mechanism 8, which includes a placement seat 80, a locking member 81, and a second spring 82. The placement seat 80 is connected to the middle of the base plate 1, and a plurality of second springs 82 are connected to the upper side of the placement seat 80. The locking member 81 is connected to the upper side of each of the second springs 82.

[0038] When using this device, the diving bell is placed on the locking member 81, which causes the diving bell below to move downward. The second spring 82 is compressed, which causes the locking member 81, which is not pressed down around it, to limit the diving bell, so that the diving bell can be placed stably, and thus facilitates the docking of the hoisting equipment with the diving bell.

[0039] like Figure 1 and Figure 10 As shown, it also includes an inflatable reinforcement mechanism 9, which includes an airbag 90 and a connecting pipe 91. The airbag 90 is connected to each of the rotation anti-sway members 53, and the connecting pipe 91 is connected to the upper side of each airbag 90.

[0040] The connecting pipe 91 can be connected to an external inflation device. After the diving bell pushes the rotating anti-sway member 53 to swing, the inflation device can be controlled to inject air into the airbag 90 through the connecting pipe 91, so that the airbag 90 can clamp the diving bell, thereby further limiting and stabilizing the diving bell.

[0041] like Figure 1 and Figure 10 As shown, it also includes a cable guiding mechanism 10, which includes a limiting wheel 101, a first guide wheel 102, and a second guide wheel 103. The left and right sides of the mounting bracket 51 are rotatably connected to two symmetrically arranged limiting wheels 101. The left and right sides of the anti-sway bracket 52 are rotatably connected to two first guide wheels 102. The lower left and right sides of the anti-sway bracket 52 are rotatably connected to the second guide wheel 103.

[0042] The hoisting rope of the hoisting equipment can contact the limiting wheel 101, then pass through the first guide wheel 102 and contact the second guide wheel 103, and then connect to the diving bell, thereby avoiding wear of the hoisting rope and thus preventing accidents during the hoisting of the diving bell.
