Description

Technical Field

[0001] The utility model belongs to the technical field of displacement monitoring, and particularly relates to a relative displacement monitoring device for a pier and a submerged tube at the joint of a ship and a tube. Background Technique

[0002] The floating transportation and installation of submerged tubes are usually carried out by an integrated transportation and installation ship. During the floating transportation and installation process, due to the influence of many factors such as the acceleration and deceleration of the integrated transportation and installation ship, wind waves, currents, and ship traveling waves, there may be micro-displacements in different directions at the semi-rigid connection between the pier of the integrated ship and the submerged tube at the joint of the ship and the tube. The micro-displacements are divided into displacements in the plane formed by the pier of the integrated ship and the submerged tube and vertical displacements in the height direction. To ensure the safety of the integrated transportation and installation ship and the floating transportation and installation of the submerged tube, it is necessary to monitor the relative displacement between the pier and the submerged tube at the joint of the ship and the tube.

[0003] In the prior art, conventional displacement monitoring means can generally be divided into two categories: contact type and non-contact type. For the contact type, a rigid or semi-rigid connection to the monitored structure is usually required to transfer the displacement between the two structures to the monitoring sensor. This method is more applicable to two static structures, but not applicable to two moving structures. Common non-contact monitoring methods include visual overall monitoring and laser single-point monitoring. Due to the influence of factors such as the flow of seawater waves, the visual imaging effect will also change, resulting in blurred visual imaging and inability to compare with the reference visual imaging diagram. Laser will undergo refraction and reflection under different conditions in the case of seawater wave flow, resulting in the monitoring results not being the structural deformation data caused by the real structural deformation. Therefore, the above monitoring means are not applicable to the relative displacement monitoring of the pier and the submerged tube at the joint of the ship and the tube.

[0004] Therefore, how to provide a relative displacement monitoring device applicable to the pier and the submerged tube at the joint of the ship and the tube is an urgent technical problem to be solved currently. Content of the Utility Model

The pier is connected to the stiffening rib to achieve a stable connection between the pier and the immersed tube. The relative displacement monitoring device for the pier and the immersed tube at the connection of the ship and the tube can be set in one or more groups according to the size of the immersed tube.

[0034] Such as Figure 1As shown, in an embodiment of the relative displacement monitoring device for the pier 3 and the immersed tube 4 at the joint of the ship's pipe in the present utility model, the relative displacement monitoring device for the pier 3 and the immersed tube 4 at the joint of the ship's pipe includes a vertical displacement monitoring mechanism 1 and two horizontal displacement monitoring mechanisms 2; wherein, the vertical displacement monitoring mechanism 1 includes a vertically arranged first magnetostrictive sensor 101 and a horizontally arranged magnetic induction ring 102, and the sensing rod of the first magnetostrictive sensor 101 is located in the magnetic induction ring 102; the first magnetostrictive sensor 101 and the magnetic induction ring 102 are respectively connected to one of the pier 3 and the immersed tube 4, and are used to monitor the vertical relative displacement between the pier 3 and the immersed tube 4; the two horizontal displacement monitoring mechanisms 2 are arranged perpendicular to each other, and are respectively used to monitor the horizontal transverse relative displacement and the horizontal longitudinal relative displacement between the pier 3 and the immersed tube 4; the horizontal displacement monitoring mechanism 2 includes a second magnetostrictive sensor 201 and a magnetic induction strip 202, the second magnetostrictive sensor 201 and the magnetic induction strip 202 are respectively connected to one of the pier 3 and the immersed tube 4, the center lines of the second magnetostrictive sensor 201 and the magnetic induction strip 202 are in the same horizontal plane and perpendicular to each other, and the sensing rod of the second magnetostrictive sensor 201 is located in the sensing area of the magnetic induction strip 202.

[0035] In the above-mentioned schematic embodiment, the relative displacement monitoring device for the pier 3 and the immersed tube 4 at the joint of the ship's pipe realizes the comprehensive monitoring of the vertical and horizontal relative displacements between the pier 3 and the immersed tube 4 through the vertical displacement monitoring mechanism 1 and the two horizontal displacement monitoring mechanisms 2, ensuring the comprehensiveness and accuracy of the monitoring; by setting the vertical displacement monitoring mechanism 1, when the pier 3 and the immersed tube 4 generate vertical displacements, the sensing rod of the first magnetostrictive sensor 101 moves up and down in the magnetic induction ring 102, and according to the induced current generated by the magnetic induction ring 102 at different positions of the first magnetostrictive sensor 101, the relative displacement between the pier 3 and the immersed tube 4 is obtained; by setting the horizontal displacement monitoring mechanism 2, when the pier 3 and the immersed tube 4 generate horizontal displacements, the sensing rod of the second magnetostrictive sensor 201 moves horizontally or longitudinally in the sensing area of the magnetic induction strip 202, and according to the induced current generated by the magnetic induction strip 202 at different positions of the second magnetostrictive sensor 201, the horizontal relative displacement or the longitudinal relative displacement between the pier 3 and the immersed tube 4 is obtained. Therefore, the relative displacement monitoring device for the pier 3 and the immersed tube 4 at the joint of the ship's pipe in the embodiment of the present utility model can timely detect and handle possible micro-displacements, ensuring the safety of the integrated transportation and installation ship and the floating transportation and installation of the immersed tube 4.

[0036] In some embodiments, such as Figure 2As shown in the figure, the vertical displacement monitoring mechanism 1 further includes a horizontally arranged mounting plate 104. When the first magnetostrictive sensor 101 is fixedly connected to the pier 3, the mounting plate 104 is hinged to the immersed tube 4; when the first magnetostrictive sensor 101 is fixedly connected to the immersed tube 4, the mounting plate 104 is hinged to the pier 3; the magnetic induction ring 102 is fixed on the mounting plate 104 and rotates horizontally with the mounting plate 104. The relative displacement between the immersed tube 4 and the pier 3 is not only the vertical relative displacement, but also the relative displacement in the horizontal direction. When the immersed tube 4 and the pier 3 have a relative displacement in the horizontal direction, the magnetic induction ring 102 is rotated by the horizontally arranged mounting plate 104, enabling the magnetic induction ring 102 to move with the immersed tube 4 or the pier 3, and avoiding jamming or damage between the first magnetostrictive sensor 101 and the magnetic induction ring 102.

[0037] In some embodiments, as Figure 2 shown in the figure, the mounting plate 104 is provided with a through hole for mounting the magnetic induction ring 102, and an installation ring 103 for fixing the magnetic induction ring 102 is provided at the through hole. Through the setting of the installation ring 103, the installation process of the magnetic induction ring 102 is simplified, and the reliability of the installation of the magnetic induction ring 102 is ensured.

[0038] In some embodiments, as Figure 2 shown in the figure, the vertical displacement monitoring mechanism 1 further includes a first base 106, and the first base 106 is hinged to the mounting plate 104 and is used for fixedly connecting to the pier 3 or the immersed tube 4. Through the setting of the first base 106, the vertical displacement monitoring mechanism 1 can be stably connected to the pier 3 or the immersed tube 4, enhancing the stability of the overall structure.

[0039] In some embodiments, as Figure 2 shown in the figure, the first base 106 is provided with a rotating shaft 105, and the mounting plate 104 is hinged to the rotating shaft 105 and rotates horizontally around the rotating shaft 105. Through the setting of the rotating shaft 105, the mounting plate 104 can rotate freely in the horizontal direction. As a schematic embodiment, the rotating shaft 105 adopts a 360° full-rotation bearing.

[0040] In some embodiments, as Figure 2 shown in the figure, the vertical displacement monitoring mechanism 1 further includes a first fixing plate 107, and the first fixing plate 107 is connected to the first magnetostrictive sensor 101 and is used for fixedly connecting to the pier 3 or the immersed tube 4. Through the setting of the first fixing plate 107, it is ensured that the first magnetostrictive sensor 101 can be stably fixed on the pier 3 or the immersed tube 4, improving the overall stability and reliability of the monitoring device.

[0041] In some embodiments, as Figure 3As shown, the horizontal displacement monitoring mechanism 2 further includes a guide rail 205. The second magnetostrictive sensor 201 is slidably connected to the guide rail 205. The guide rail 205 is fixedly connected to the pier 3 or the immersed tube 4, and is used to eliminate the horizontal deflection angle between the second magnetostrictive sensor 201 and the magnetic induction strip 202. The horizontal relative displacement includes the lateral relative displacement and the longitudinal relative displacement. When two horizontal displacement monitoring mechanisms 2 are arranged perpendicular to each other, taking one of the horizontal displacement monitoring mechanisms 2 as a reference, the horizontal relative displacement can be regarded as including the lateral relative displacement along the direction of its guide rail 205 and the longitudinal relative displacement perpendicular to the direction of its guide rail 205. When the lateral relative displacement along the direction of its guide rail 205 occurs, the positions of the magnetic induction strip 202 and the second magnetostrictive sensor 201 change, so that the induced current of the second magnetostrictive sensor 201 changes, thereby obtaining the data of the lateral relative displacement; when the longitudinal relative displacement perpendicular to the direction of its guide rail 205 occurs, another horizontal displacement monitoring mechanism 2 should be used for detection. For the horizontal displacement monitoring mechanism 2 used as a reference, the second magnetostrictive sensor 201 can slide along the guide rail 205, so that no horizontal deflection angle is generated between the magnetic induction strip 202 and the magnetostrictive sensor, and the data during monitoring is more accurate.

[0042] Further, as Figure 3 shown, a slider 206 is provided on the guide rail 205. The second magnetostrictive sensor 201 is fixedly connected to the slider 206. Through the arrangement of the slider 206, it is ensured that the sensor can slide smoothly, and the accuracy of monitoring is further improved.

[0043] In some embodiments, as Figure 3 shown, the horizontal displacement monitoring mechanism 2 further includes a second base 207. The second base 207 is fixedly connected to the guide rail 205 and is used to be fixedly connected to the pier 3 or the immersed tube 4. Through the arrangement of the second base 207, the horizontal displacement monitoring mechanism 2 can be stably connected to the pier 3 or the immersed tube 4, enhancing the stability of the overall structure.

[0044] In some embodiments, as Figure 3 shown, a second fixing plate 208 is provided between the slider 206 and the second magnetostrictive sensor 201. The second fixing plate 208 is L-shaped. One side of the L-shaped second fixing plate 208 is fixed to the slider 206, and the other side of the L-shaped second fixing plate 208 is fixed to the second magnetostrictive sensor 201. Through the arrangement of the second fixing plate 208, it is ensured that the fixation between the second magnetostrictive sensor 201 and the slider 206 is more stable.

[0045] In some embodiments, as Figure 3As shown, the horizontal displacement monitoring mechanism 2 further includes two parallel link rods 203. The first ends of the two link rods 203 are respectively installed at both ends of the magnetic induction strip 202, and the second ends of the two link rods 203 are respectively hinged to the abutment 3 or the immersed tube 4.

[0046] In some embodiments, as Figure 3 shown, an adjusting rod 204 is further provided between the two link rods 203. Both ends of the adjusting rod 204 are respectively slidably connected to the two link rods 203. The adjusting rod 204 is arranged in parallel with the magnetic induction strip 202 and fixedly connected. The adjusting rod 204 is used to adjust the height of the magnetic induction strip 202. Through the arrangement of the adjusting rod 204, the height of the magnetic induction strip 202 can be flexibly adjusted to ensure that the magnetic induction strip 202 is horizontally installed.

[0047] Furthermore, as Figure 3 shown, sliding nuts are provided at the joints of the adjusting rod 204 and the two link rods 203, and the two link rods 203 are both provided with matching sliding grooves. After loosening the sliding nuts, the height of the adjusting rod 204 can be adjusted along the sliding grooves. After adjusting to the required angle, the sliding nuts can be tightened. Through the arrangement of the sliding nuts and the sliding grooves, the height of the adjusting rod 204 can be conveniently adjusted to ensure that the monitoring device can adapt to different installation requirements and improve the convenience of operation.

[0048] In some embodiments, as Figure 3 shown, the horizontal displacement monitoring mechanism 2 further includes a third fixing plate 209. The third fixing plate 209 is hinged to the second ends of the two link rods 203 and is used for fixedly connecting to the abutment 3 or the immersed tube 4.

[0049] Furthermore, as Figure 3 shown, fixing nuts are provided at the joints of the third fixing plate 209 and the two link rods 203. After loosening the fixing nuts, the inclination angle of the link rods 203 can be adjusted. After adjusting to the required angle, the fixing nuts can be tightened.
