Description

Technical Field

[0001] This utility model relates to an underwater equipment release device, and more particularly to a release device capable of simultaneously releasing multiple underwater devices (deployed objects), belonging to the field of marine construction equipment technology. Background Technology

[0002] Currently, in offshore construction operations, underwater equipment (deployed objects) needs to be lowered to the seabed and then released to complete the deployment operation. For example, Chinese patent CN219115690U discloses an "underwater release device" that hoists the underwater equipment (deployed object) to the seabed and releases it electromagnetically. However, the electromagnetic control structure of this device is complex and prone to malfunction. Especially when releasing heavy deployed objects, the aforementioned underwater release device suffers from insufficient load-bearing capacity and low efficiency. Therefore, there is an urgent need for an underwater equipment release device that can solve these problems. Summary of the Invention

[0003] The purpose of this utility model is to overcome the above-mentioned shortcomings and provide a multi-channel underwater equipment release device that can simultaneously deploy multiple underwater devices (deployed objects) and continuously supply underwater devices (deployed objects) during the deployment process to achieve continuous operation.

[0004] The purpose of this utility model is achieved as follows:

[0005] A multi-channel underwater equipment release device includes at least one set of deployment devices mounted on an installation platform. The main body of the deployment device is a chain conveyor. The upper part of the deployment device is hinged to the installation platform, and the middle part of the deployment device is hinged to the installation platform via a lower adjusting cylinder. Multiple baffles are provided on the chain plate of the deployment device.

[0006] Preferably, the baffles are evenly distributed and perpendicular to the chain plate of the deployment device.

[0007] Preferably, the upper and lower parts of the installation platform are equipped with multiple sets of upper supports and lower supports respectively. The upper housing of the deployment device has upper rotating shafts on both sides of its outer wall. The rotating shafts are hinged to one end of the upper connecting plate, and the other end of the upper connecting plate is fixedly connected to the upper support. The middle housing of the deployment device has lower connecting plates fixedly connected to both sides of its outer wall. The end of the lower connecting plate is hinged to the telescopic rod of the lower adjusting cylinder, and the base of the lower adjusting cylinder is hinged to the lower support.

[0008] Preferably, the lower connecting plate is provided with two connecting lugs. After the telescopic rod of the lower adjusting cylinder is inserted between the two connecting lugs, a short shaft passes through the connecting lugs and the telescopic rod of the lower adjusting cylinder.

[0009] Preferably, the object is placed on the chain plate of the deployment device, and the object slides diagonally downward against the baffle plate.

[0010] Preferably, the object being deployed is equipped with a traction ring, one end of the guide rope is fixed to the winch on the ship, and the other end passes through the traction ring and is tied to the ship.

[0011] Preferably, the mounting platform is a mounting frame structure located at the stern of the ship.

[0012] Preferably, the installation platform is a stern plate.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] This invention utilizes a chain conveyor as a deployment device for deployment operations. Compared to conventional hoisting and release methods, the chain conveyor structure enables continuous operation, significantly improving work efficiency. Furthermore, the chain conveyor, by supporting the deployed object through its chain plates, possesses higher load-bearing capacity and better operational stability. Simultaneously, depending on the working environment and requirements, multiple deployment devices can be set up for synchronized construction, further enhancing work efficiency. A simple rope release structure consisting of a traction ring and a guide rope can also be incorporated, further improving safety. Attached Figure Description

[0020] Installation platform 101, deployment device 102, deployment object 103;

[0021] Upper support 1, lower support 2, upper rotating shaft 3, upper connecting plate 4, lower adjusting cylinder 5, lower connecting plate 6, baffle plate 7, traction ring 8, guide rope 9; Detailed Implementation

[0022] See Figures 1-4The present invention relates to a multi-channel underwater equipment release device, which includes multiple sets of deployment devices 102 set on an installation platform 101. The installation platform 101 is an installation frame structure (such as a stern plate) set on the stern of a ship.

[0023] The main body of the deployment device 102 is a chain conveyor. The upper part of the deployment device 102 is hinged to the installation platform 101, and the middle part of the deployment device 102 is hinged to the installation platform 101 via a lower adjusting cylinder 5. Specifically, multiple sets of upper supports 1 and lower supports 2 are installed on the upper and lower parts of the installation platform 101, respectively. Upper rotating shafts 3 are provided on both sides of the outer wall of the upper housing of the deployment device 102. The rotating shafts 3 are hinged to one end of the upper connecting plate 4, and the other end of the upper connecting plate 4... The end is fixedly connected to the upper support 1; both sides of the outer wall of the middle housing of the placement device 102 are fixedly connected to the lower connecting plate 6, and the end of the lower connecting plate 6 is hinged to the telescopic rod of the lower adjusting cylinder 5 (in this embodiment, two connecting ear plates are provided on the lower connecting plate 6, and after the telescopic rod of the lower adjusting cylinder 5 is inserted between the two connecting ear plates, a short shaft passes through the connecting ear plate and the telescopic rod of the lower adjusting cylinder 5). The base of the lower adjusting cylinder 5 is hinged to the lower support 2.

[0024] The deployment device 102 has multiple L-shaped grid plates 7 evenly arranged on the chain plate, and the horizontal plates of the grid plates 7 are connected to the chain plate by bolts, and the vertical plates are perpendicular to the chain plate.

[0025] The working principle of this utility model is as follows:

[0026] Step 1: The underwater equipment (deployment object) is placed on the deployment device 102 by the crane on the deck of the construction vessel, and is blocked by a certain grid baffle 7;

[0027] Step 2: After the deployment device 102 is started, the chain plate carries the underwater equipment (deployed object) downward. During this process, the crane places another underwater equipment (deployed object) at the next baffle 7.

[0028] Step 3: When the deployed object 103 reaches the seabed (the transmission speed of the deployment device 102 is controllable, and the timing of the deployment object 103 being released onto the seabed can be known by controlling the deployment device 102), the underwater equipment (deployed object) will naturally slide down to the seabed as the baffle plate 7 rotates to the back of the deployment device 102.

[0029] Step 4: After the construction vessel travels a certain distance (such as 6km in this embodiment) according to the construction specifications, the second deployment object 103 is slid down and placed on the seabed. During this process, the speed of the deployment device 102 can be controlled to match the sailing speed for synchronous operation, or the deployment device 102 can be turned off and then activated after reaching the destination to place the corresponding underwater equipment (deployment object).

[0030] By repeating steps 1-4 above, continuous operation can be achieved.

[0031] In step 1, multiple deployment devices 102 can be set up simultaneously for synchronous construction (such as four in this embodiment), which greatly improves work efficiency.

[0032] Meanwhile, in step 1, depending on the construction environment, seabed depth, etc., the angle of the deployment device 102 can be adjusted by adjusting the lower hydraulic cylinder 5, such as the adjustment angle of 25~50° in this embodiment.

[0033] In addition, in this embodiment, a guide rope 9 can be set up to provide double protection. In this case, a traction ring 8 needs to be set on the deployment object 103 placed in step 1. One end of the guide rope 9 is fixed to the winch on the ship, and the other end passes through the traction ring 8 and is tied to the ship. When the deployment object 103 reaches the seabed, the end of the guide rope 9 tied to the ship is released. Then, the winch works to pull the guide rope 9 upward. During this upward process, the guide rope 9 passes through the traction ring 8, thereby releasing the deployment object 103 with the guide rope 9.

[0034] Additionally, it should be noted that the above-described specific implementation is merely an optimized solution of this patent, and any modifications or improvements made by those skilled in the art based on the above concept are within the scope of protection of this patent.
