Description

Technical Field

[0001] This invention relates to a fully automatic marine buoy deployment and recovery device and its operating method, which belongs to the technical field of marine buoy transfer. Background Technology

[0002] Marine buoys play a vital role in marine engineering and construction. They can be used to mark construction locations, determine the driving points of foundation piles, and provide accurate positioning references for engineering construction. They can also serve as mooring buoys to secure offshore platforms, ships, buoys, cables, and other objects, maintaining their stable position at sea and resisting the effects of wind, waves, and ocean currents.

[0003] Deploying and recovering buoys at sea involves significant costs. Deploying buoys requires vessels and specialized personnel and equipment, resulting in high transportation and labor costs. This is especially true in deep or remote waters, where deployment and recovery are more challenging and costly. During recovery, the safety of personnel must be ensured to prevent accidents. Appropriate tools and equipment, such as winches and cranes, should be used, and operations must be strictly followed according to procedures. When hooking the cable to pull the buoy back, care must be taken with force and direction to prevent cable breakage or loss of buoy control.

[0004] The heart-shaped buoys used on offshore platforms are made of elastic material, about 1 meter in diameter, and are not perfectly round but heart-shaped. The tip of the buoy is equipped with a hook ring. Due to the shape limitations of these irregularly round buoys, as well as the limited space for offshore platform placement, the humid and swaying marine environment, conventional transportation methods are difficult to use for the deployment, transportation and retrieval of these buoys. Summary of the Invention

[0005] To address the aforementioned problems, this invention provides a fully automatic marine buoy deployment and retrieval device that enables the storage and stable, orderly release of large buoys on a marine platform without the main body being powered, and can achieve fully automatic retrieval.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A fully automatic marine buoy deployment and retrieval device includes a support frame that supports an electric roller conveyor. The electric roller conveyor includes a straight roller conveyor, a spiral roller conveyor, and a flat roller conveyor. The head end of the roller conveyor is located at one end of the straight roller conveyor, and the other end of the straight roller conveyor is connected to the spiral roller conveyor. The spiral roller conveyor spirals upwards from low to high, and the other end of the spiral roller conveyor is connected to one end of the flat roller conveyor, which is the tail end of the roller conveyor. The height of the tail end of the roller conveyor is higher than the height of the head end. A buoy placement platform is located at the center of the spiral roller conveyor. The inclination angle of the straight roller conveyor is 4°-7°, the spiral angle of the spiral roller conveyor is 4°-7°, and the flat roller conveyor is horizontal with no inclination angle.

[0008] The straight roller conveyor, spiral roller conveyor, and flat roller conveyor all adopt a roller conveyor structure. In the roller conveyor structure, two roller supports are symmetrically arranged on the roller keel. A sliding groove for the float ball to move is formed between the two roller supports. Roller rollers driven by motors are evenly distributed on the roller supports. The roller supports are inclined at 120°-150° to the bottom surface of the roller conveyor.

[0009] A float deployment platform is installed at the beginning of the roller conveyor. An intermittent deployment plate is installed on the platform base via a deployment platform support. The intermittent deployment plate is mounted on the deployment platform support via a deployment platform pivot. One side of the deployment platform pivot is a limiting end, and the other side is a deployment end. The weight of the limiting end is greater than the weight of the deployment end, and the weight of the deployment end and the float carrier with the float is greater than the weight of the limiting end. The intermittent deployment plate rotates around the pivot according to the weight difference on both sides of the deployment platform pivot, realizing the intermittent deployment of the float. An adjustment plate support is installed on the back of the adjustment plate in the deployment end, and a deployment ramp is installed on the outer end of the adjustment plate. A platform roller is installed on the adjustment plate.

[0010] The device also includes a float carrier for transporting the floats, with the inclined surface of the carrier at the bottom acting on the roller conveyor.

[0011] The straight roller conveyor, spiral roller conveyor, and flat roller conveyor are equipped with roller conveyor side guardrails for limiting floats on both sides; a top steel pipe is installed above the straight roller conveyor, spiral roller conveyor, and flat roller conveyor.

[0012] A deceleration curtain is installed above the electric roller conveyor to reduce the speed of the float.

[0013] The roller conveyor is provided with a straight stop bar and a U-shaped stop bar at the beginning of the roller conveyor.

[0014] The buoy carrier has a rubber-covered oblique section, and the oblique angle of the carrier is the same as the oblique angle of the roller conveyor.

[0015] The operating method of a fully automated marine buoy deployment and retrieval system includes the following steps:

[0016] S1. Automatic placement of floating balls:

[0017] Place the floats in the float carrier and put them into the device from the beginning of the roller at the lowest point of the straight roller conveyor. The inclined surface of the carrier is attached to the roller of the roller conveyor. Turn on the motor to reverse the direction, so that the roller of the roller conveyor rotates in the opposite direction. The floats will be transported to the end of the roller conveyor at the top of the spiral roller conveyor along with the carrier. They are stacked and arranged in sequence until all the floats are stacked.

[0018] S2. Storage of the float:

[0019] The floats are stored on straight roller conveyors and spiral roller conveyors. During storage, the straight stop bar and the U-shaped stop bar at the beginning of the roller conveyor are closed.

[0020] S3. Transport of the buoy:

[0021] During transportation, first open the straight stop bar at the beginning of the roller conveyor, turn on the motor, and let the rollers arranged on the roller support rotate smoothly, so that the floats are transported down to the float deployment platform in sequence with the float carrier;

[0022] S4. Float deployment:

[0023] After the buoy carrier is transported to the buoy deployment platform, it continues to be pushed by the roller conveyor rollers past the limit end and the deployment platform shaft. When the buoy carrier moves to the deployment end, the weight of the buoy carrier with the buoy and the deployment end is greater than the weight of the limit end. The limit end automatically tilts up, reaches the upper limit position, and stops the next buoy carrier. The motor is turned off, and the U-shaped stop bar at the beginning of the roller conveyor stops the movement of the buoy carrier and the buoy. The operator adjusts the position of the buoy carrier by adjusting the platform rollers on the adjustment plate to complete the connection between the buoy and the target object. The U-shaped stop bar at the beginning of the roller conveyor is lifted, and the carrier is tilted downwards to let the buoy fall into the water. The buoy carrier is then removed and stored for later use. Then the limit end falls freely and contacts the inner surface of the roller keel, reaching the lower limit position. The above buoy deployment steps are repeated to complete the deployment of all buoys.

[0024] Specifically, the decoration includes a support frame, a straight roller conveyor and a spiral roller conveyor. The spiral roller conveyor extends upward in a spiral shape at a fixed angle, with two layers. To control the overall height of the device, the upper roller conveyor does not rise further at its end and is designed as a horizontal roller conveyor. The straight roller conveyor is located at the end of the lower roller conveyor of the spiral roller conveyor.

[0025] Both the straight roller conveyor and the spiral roller conveyor adopt a roller conveyor structure. In the roller conveyor structure, two roller supports are symmetrically arranged on the roller keel. A chute for the movement of the float carrier is formed between the two roller supports. Rollers are evenly distributed on the roller supports. The roller supports are inclined at 120°-150° with the horizontal plane.

[0026] A float deployment platform is set at the first end of the straight roller conveyor. The deployment platform support is set on the platform plate. The limiting end and the deployment end are fixed as one piece. The two ends of the deployment platform shaft are set in the deployment platform support. The limiting end and the deployment end will rotate around the deployment platform shaft. The weight of the limiting end is greater than the weight of the deployment end, and the weight of the limiting end is less than the sum of the weight of the deployment end and one float.

[0027] The first end of the roller conveyor is provided with a straight stop bar and a U-shaped stop bar.

[0028] The device also includes a buoy carrier for transporting buoys.

[0029] Furthermore, a top steel pipe is installed above the straight roller conveyor and the spiral roller conveyor, and the top steel pipe is installed on top of the support frame. Roller side guardrails for limiting floats are installed on the side walls of the straight roller conveyor and the spiral roller conveyor.

[0030] Furthermore, a deceleration curtain is installed on the straight roller conveyor and the spiral roller conveyor.

[0031] Furthermore, a float placement platform is provided at the beginning of the straight roller conveyor, and an adjustment plate is provided above the float placement platform at the beginning of the straight roller conveyor, with platform rollers provided on the adjustment plate.

[0032] Furthermore, the float carrier is made of lightweight perforated material, with its bottom shape conforming to the angle of the roller, and the bottom layer covered with rubber, which can increase the friction with the roller surface.

[0033] The beneficial effects of this invention are:

[0034] The device includes an electric roller conveyor, a float deployment platform, a support frame, and a float carrier. The electric roller conveyor is equipped with rollers and works in conjunction with the float carrier to carry out fully automated transport of floats under electric drive.

[0035] The floats are placed in a float carrier and inserted into the device from the lowest point of the straight roller conveyor. The inclined surface of the carrier fits against the rollers of the conveyor. The motor is turned on in reverse, causing the rollers to rotate in the opposite direction. The floats are then conveyed by the carrier to the end of the spiral roller conveyor, and the floats are stacked sequentially until all floats are stacked. This method allows for the retrieval of floats over 1 meter long, avoiding the use of high-altitude tools such as winches and cranes, thus ensuring the safety of the operators.

[0036] The coordination of the roller conveyor with the top steel pipe, side guardrails, U-shaped stop at the beginning of the roller conveyor, and straight stop at the beginning of the roller conveyor ensures the safety of the buoys during transportation. To prevent the buoys from accidentally rolling off the electric roller conveyor during storage and transportation, side guardrails are installed on both sides of the electric roller conveyor. Furthermore, for easy adjustment in case of system malfunction, the side guardrails are divided into sections and are easily removable. Considering the rough seas and rough terrain during maritime navigation, a top steel pipe is installed on the electric roller conveyor to prevent the buoys from jumping off. During transportation, workers can adjust the buoy carriers that may get stuck in the roller conveyor via the buoy placement platform in the center of the support frame, assisting in the smooth transportation of the buoys.

[0037] The device also employs an intermittent deployment plate to achieve intermittent deployment of buoys. It rotates around the axis according to the different weights on both sides of the deployment platform's rotating shaft to achieve intermittent deployment. This invention can automatically recover and stably store large buoys in an offshore platform environment, control the speed and position of the buoys, and ensure that the buoys are transported smoothly and safely to the release position and released sequentially.

[0048] Figures 1 to 8 A fully automatic marine buoy deployment and retrieval device is shown, comprising a support frame 8. The device includes a straight roller conveyor 1a and a spiral roller conveyor 1b. The straight roller conveyor 1a is located below and connected to the spiral roller conveyor 1b. Both the straight roller conveyor 1a and the spiral roller conveyor 1b adopt a roller conveyor structure. In the roller conveyor structure, two roller supports 1e are symmetrically arranged on the roller keel 1f. A chute for the movement of the buoy carrier is formed between the two roller supports 1e. Roller rollers 1g are evenly distributed on the roller supports 1e. The roller supports 1e are inclined at 135° to the horizontal plane. The inclination angle of the straight roller conveyor 1a is 5°, and the spiral angle in the spiral roller conveyor 1b is also 5°. The tail end of the spiral roller conveyor 1b is connected to a horizontally arranged flat roller conveyor 1h.

[0049] A float deployment platform 6 is set at the first end 1c of the straight roller conveyor 1a. The deployment platform support 6d is set on the platform base plate 6i. The limiting end 6a and the deployment end 6b are fixed as one piece. The two ends of the deployment platform rotating shaft 6c are set in the deployment platform support 6d. The limiting end 6a and the deployment end 6b rotate around the deployment platform rotating shaft 6c. The weight of the limiting end 6a is greater than the weight of the deployment end 6b, and the weight of the limiting end 6a is less than the sum of the weight of the deployment end 6b, a float and the float carrier 9.

[0050] The roller conveyor 1a has a roller conveyor head end 1c equipped with a roller conveyor head end straight stop bar 5a and a roller conveyor head end U-shaped stop bar 5. The device also includes a float carrier 9 for transporting floats.

[0051] In some embodiments, a top steel pipe 3 is provided above the straight roller conveyor 1a and the spiral roller conveyor 1b, and the top steel pipe 3 is provided on the top of the support frame 8.

[0052] In some embodiments, roller side guardrails 4 for limiting floats are provided on the side walls of the straight roller conveyor 1a and the spiral roller conveyor 1b.

[0053] In some embodiments, a deceleration curtain 7 is provided at appropriate positions on the straight roller conveyor 1a and the spiral roller conveyor 1b.

[0054] In some embodiments, an adjustment plate 6f is provided in front of the float placement platform 6 at the beginning of the straight roller conveyor 1a, and a platform roller 6e is provided on the adjustment plate 6f.

[0055] When using the above technical solution, the following steps are included:

[0056] S1. Automatic placement of floating balls:

[0057] Place the float in the float carrier 9 and put it into the device from the first end 1c of the straight roller 1a at the lowest point of the device. The inclined surface 9a of the carrier has a chamfer that fits the angle of the roller 1g of the roller 1g. Turn on the motor 2 to reverse the direction, so that the roller 1g of the roller 1g rotates in the opposite direction. The float will be transported to the top of the spiral roller 1b along with the carrier to complete the stacking of all the floats.

[0058] S2. Storage of the float:

[0059] The floats are stored on the straight roller conveyor 1a and the spiral roller conveyor 1b, and the stop lever is closed during storage;

[0060] S3. Transport of the buoy:

[0061] During transportation, first open the straight stop bar 5a at the beginning of the roller conveyor 1c, turn on the motor 2, and make the rollers 1g arranged on the roller support 1e rotate smoothly, so that the floats are transported downwards in sequence with the float carrier 9 to the float deployment platform 6.

[0062] S4. Float deployment:

[0063] When the float carrier 9, carrying the float, arrives at the float deployment platform 6, it is further pushed by the roller 1g past the limiting end 6a and the deployment platform pivot 6c. In its initial state, the limiting end 6a of the float deployment platform 6 falls freely and contacts the inner surface of the roller keel 1f, reaching its lower limit position. The float carrier 9 is then pushed by the roller 1g past the limiting end 6a and the deployment platform pivot 6c. When the float carrier 9 moves to the deployment end 6b, the combined weight of the float carrier 9 with the float and the deployment end 6b exceeds the weight of the limiting end 6a, causing the limiting end 6a to automatically tilt upwards, reaching its upper limit. Position the float carrier 9 and stop it from moving. When the float moves to the float placement platform 6 at the end of the straight roller conveyor 1a, it is blocked by the U-shaped stop bar 5 at the beginning of the roller conveyor, and the float carrier 9 stops moving with the float. After the worker completes the connection between the float and the target object, lift the U-shaped stop bar 5 at the beginning of the roller conveyor. After adjusting the posture of the platform roller 6e on the adjustment plate 6f, tilt the float carrier 9 downwards and let the float fall into the water. Remove the float carrier 9 and store it for later use. Then the limiting end 6a falls freely. Repeat the above float placement steps to complete the placement of all floats. During transportation, the worker can adjust the float carrier 9 that may get stuck in the roller conveyor 1 through the float placement platform 10 in the center of the support frame 8 to assist in the smooth transportation of the floats.

[0064] The device consists of an electric roller conveyor (1), a motor (2), a top steel pipe (3), roller side guardrails (4), stop bars (5), a float deployment platform (6), a deceleration curtain (7), a support frame (8), and a float carrier (9). Its structure is as follows: Figure 1 As shown, the system can hold a total of 26 floats.

[0065] The structure of electric roller conveyor 1 is as follows Figure 4 As shown, rollers 1g are evenly distributed on each side of the roller support 1e to transport the floats. Since the floats are heart-shaped spheres, the deployment, retrieval and transportation of the floats are assisted by the float carriers 9 at 135° on both sides. For easy stacking, an electric roller conveyor suspended in the middle is used.

[0066] When recovering the buoys, the buoys and buoy carriers 9 are first manually placed into the device from the first end 1c of the straight roller conveyor at the lowest point of the roller conveyor. Then, the motor 2 of the device is turned in reverse, and the roller 1g of the roller conveyor rotates to transport the buoy carriers 9 along the roller conveyor into the device. All carriers containing buoys are placed in sequence, ensuring that the carriers are as close to each other as possible. Finally, all buoys are recovered and stacked.

[0067] The storage of the floats relies on electric roller conveyor 1, and during storage, they will be stored as follows: Figure 5 The straight stop bar 5a at the beginning of the straight roller conveyor shown is closed. When it needs to be opened, it can be pulled out horizontally.

[0068] To prevent the buoys from accidentally rolling off the electric roller conveyor 1 during storage and transportation, side railings 4 are installed on both sides of the electric roller conveyor 1. Furthermore, for easy adjustment in case of system malfunction, the side railings 4 are divided into sections for easy disassembly. Considering the rough seas and rough conditions during maritime navigation, a top steel pipe 3 is installed on the electric roller conveyor 1 to prevent the buoys from jumping off.

[0069] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
