Description

Technical Field

[0001] This utility model relates to the technical field of marine engineering, and in particular to a dragging anchor pool for dragging anchor impact testing. Background Technology

[0002] Anchor impact experiments are a specialized research experiment conducted on the behavior of ships dragging anchors. The core purpose is to explore the impact risk and damage mechanism of the anchor body on seabed facilities during the process of ships dragging anchors.

[0003] In the experiments used, it is necessary to simulate the anchoring scenarios of ships under different environmental conditions and operating conditions. Through physical model tests or numerical simulations, the anchor body is made to collide with the seabed facility model. During the process, it is necessary to accurately measure data such as the peak impact force, the time of impact, the deformation of the facility, and the stress distribution of materials, and analyze the influence of different parameters on the impact consequences to reveal the mechanical nature and damage mode of anchoring impact.

[0004] However, during the experiment, the anchoring pool could not secure the internal hydraulic structures, so the waves generated by the moving anchor could cause the hydraulic structures to shift, resulting in a deviation in the impact point between the anchor and the hydraulic structures, which would affect the experimental results.

Detailed Implementation

[0024] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0025] Reference Figure 1-6An anchoring tank for anchor impact testing includes a tank body 1, with a structural body 2 inside the tank body 1. A movable slide groove 3 is formed on the inner wall of the tank body 1. A clamping assembly is installed inside the movable slide groove 3. The clamping assembly includes a limiting slide groove 301, a bidirectional lead screw 302, a separator block 303, a limiting slider 304, a clamping plate 305, and a stepper motor 306. The limiting slide groove 301 is formed on the inner wall of the movable slide groove 3, and the bidirectional lead screw 302 is rotatably connected to the movable slide groove 304. Inside the groove 3, the partition block 303 is fixedly connected to the inside of the movable slide groove 3. The bidirectional lead screw 302 passes through the inside of the partition block 303. The limiting slider 304 is symmetrically distributed on the left and right and is movably installed inside the limiting slide groove 301. It is threadedly connected to the bidirectional lead screw 302. The clamping plate 305 is fixedly connected to the side of the limiting slider 304 away from the movable slide groove 3. The stepper motor 306 is fixedly installed on the left side of the water tank body 1. The stepper motor 306 is connected to the bidirectional lead screw 302 for transmission.

[0026] The limiting slider 304 is slidably engaged with the limiting groove 301, and the structure body 2 is located between the clamping plates 305. The clamping assembly is configured such that by activating the stepper motor 306, the transmission end of the stepper motor 306 drives the bidirectional lead screw 302 to rotate. During rotation, due to the limiting groove 301 limiting the limiting slider 304 and the threaded connection between the limiting slider 304 and the bidirectional lead screw 302, the clamping plates 305 on both sides can be moved closer to the separator block 303. After moving a certain distance, the clamping plates 305 will clamp and fix the structure body 2. This invention, through the clamping assembly, ensures that the structure body 2 is clamped and fixed by the clamping plates 305 during placement, thereby improving the stability of the structure body 2 during placement, preventing displacement due to waves, and effectively improving the accuracy of experimental results.

[0027] Furthermore, a support frame 6 is fixedly installed on the top of the pool body 1, a variable speed winch 7 is fixedly installed on the top of the support frame 6, a rope groove 8 is fixedly connected to the pulling shaft of the variable speed winch 7, an anchor 9 is provided at the other end of the rope groove 8, and a drain outlet 10 is provided on the left side of the pool body 1.

[0028] The support frame 6 is used to support the variable speed winch 7. The opening of the rope groove 8 makes it convenient for the variable speed winch 7 to pull the anchor 9 through the wire rope, thereby avoiding friction between the wire rope and the support frame 6 and improving the safety of the wire rope.

[0029] Furthermore, the bottom of the support frame 6 is provided with a movable component, which includes a movable slide 601, a slide rail 602, and a sliding trolley 603. The movable slide 601 is symmetrically distributed on the top of the pool body 1. The slide rail 602 is fixedly connected to the inside of the movable slide 601. The sliding trolley 603 is slidably installed inside the movable slide 601 and is adapted to the slide rail 602. The sliding trolley 603 is fixedly connected to the support frame 6.

[0030] The moving component is set up so that the sliding trolley 603 is activated and slides on the outside of the slide rail 602, thereby driving the support frame 6 and the anchor 9 to move, thus conducting the anchor dragging impact test.

[0031] Furthermore, a passenger car 4 is fixedly installed inside the water tank body 1. The side of the passenger car 4 and the inside of the water tank body 1 are provided with lifting components. The lifting components include a car slide 401, a second limiting slide 402, a one-way screw 403, a second limiting slider 404 and a threaded hole 405. The car slide 401 is opened on the inner wall of the water tank body 1.

[0032] The second limiting slide groove 402 is opened on the inner wall of the car slide groove 401. The one-way screw 403 is rotatably connected to the inside of the second limiting slide groove 402. The lower end of the one-way screw 403 is driven and connected to the second stepper motor. The second limiting slider 404 is fixedly connected to the rear end of the passenger car 4 and is adapted to the second limiting slide groove 402. The threaded hole 405 is opened inside the second limiting slider 404 and is threadedly connected to the one-way screw 403.

[0033] The installation of the passenger car 4 facilitates the descent of staff into the interior of the pool body 1. The lifting assembly is designed so that by activating the second stepper motor, the second stepper motor drives the one-way lead screw 403 at the transmission end to rotate. During the rotation of the one-way lead screw 403, the threaded connection between the second limit slider 404 and the one-way lead screw 403, and the limitation of the second limit slide groove 402 on the second limit slider 404, drive the passenger car 4 to move up and down. Therefore, it is possible to drive the passenger car 4 to move up and down, thus facilitating the transport of staff into the interior of the pool body 1.

[0034] This utility model, through the setting of the lifting component, enables the passenger car 4 to move up and down by rotating the one-way screw 403, which facilitates the staff to enter the interior of the water tank body 1 and effectively improves the convenience of the staff's experimental work.

[0035] Furthermore, a protective railing 5 is fixedly installed on the top of the pool body 1, and a storage component is provided at the bottom of the protective railing 5. The storage component includes a storage groove 501 and a hydraulic push rod 502. The storage groove 501 is opened on the top of the pool body 1, and the hydraulic push rod 502 is fixedly installed inside the storage groove 501, and the telescopic end of the hydraulic push rod 502 is fixedly connected to the protective railing 5.

[0036] The installation of guardrail 5 can protect the staff outside the pool body 1. The installation of the storage component makes it convenient to store and raise / lower the guardrail 5.

[0037] In summary:

[0038] When using this utility model, the workers first place the main body 2 of the structure inside the main body 1 of the pool using a crane, and place it between the clamps 305;

[0039] Then, stepper motor 306 can be started, which will drive the bidirectional lead screw 302 to rotate. During the rotation of the bidirectional lead screw 302, due to the limiting slide groove 301 limiting the limiting slider 304 and the threaded connection between the limiting slider 304 and the bidirectional lead screw 302, the clamping plates 305 on both sides can be driven to move closer to the partition block 303. After the clamping plates 305 on both sides have moved a certain distance, they will clamp the structure body 2 and fix the structure body 2.

[0040] Then, appropriate water is injected into the interior of the pool body 1, and the hydraulic push rod 502 is activated, so that the telescopic end of the hydraulic push rod 502 drives the guardrail 5 to rise, thus protecting the area around the pool body 1.

[0041] Then, start the variable speed winch 7 to lower the anchor 9, so that the anchor 9 is submerged in the water and level with the structure body 2. Then, start the sliding car 603, so that the sliding car 603 slides on the outside of the slide rail 602, thereby driving the support frame 6 and the anchor 9 to move, so as to carry out the anchor dragging impact test.

[0042] After the anchor 9 and the main body of the structure 2 collide, the staff can drain the water inside the pool body 1 through the drain outlet 10 and descend into the pool body 1 in the passenger car 4 to collect data.
