Abstract
Description
Technical Field
[0001] This application relates to the field of underwater depth sounding technology, and in particular to a ship-mounted anti-tethering support. Background Technology
[0002] Detectors are typically fixed to the ship's hull using a fixed mounting structure. This involves attaching a detection rod to the outer wall of the hull, with the detector mounted at its lower end. The detector can be a single-beam echo sounder, pipeline detector, multi-beam echo sounder, or shallow seismic profiler. However, during operation, this fixed detection structure frequently encounters snagging issues, where the lower part of the detection rod gets caught on fishing nets, seaweed, or other debris in the water. If the ship continues to move in this situation, the detection rod will be subjected to significant tensile force, easily causing bending and deformation, thus affecting subsequent measurements. Therefore, further improvements are needed. Utility Model Content
[0003] To reduce the possibility of bending deformation of the probe, this application provides a ship-mounted anti-tethering bracket.
[0004] The technical solution for a fixed-installation anti-trailing bracket for ships provided in this application is as follows:
[0005] A ship-mounted anti-traction bracket includes a hull and a detection rod. A pivot is rotatably connected to the outer wall of the hull, with the axis of the pivot perpendicular to the outer wall of the hull. A mounting sleeve is fixedly connected to the pivot, with the axis of the mounting sleeve perpendicular to the axis of the pivot. The detection rod passes through the mounting sleeve. An external force damage pin is detachably connected to the outer wall of the hull, located above the pivot, and abuts against the upper side wall of the detection rod.
[0006] By adopting the above technical solution, when the lower part of the detection rod encounters a net, the ship continues to move forward. The lower part of the detection rod is pulled and tends to swing around the axis of rotation towards the rear of the hull. The upper part of the detection rod is subjected to a force around the axis of rotation towards the front. When the external force damages the pin, it will be crushed by the detection rod after the force reaches its upper limit. This causes the detection rod to rotate around the axis of rotation, allowing the detection rod to get rid of the obstacle and reducing the possibility of bending deformation. After the detection rod gets rid of the obstacle, it will rotate back to its original position, and the external force damaged pin will be replaced to continue the detection operation.
[0007] Preferably, there are two external force damage pins, which abut against the upper two side walls of the probe rod respectively.
[0008] By adopting the above technical solution, setting two externally damaged pins can keep the probe rod in a vertical state under normal conditions.
[0009] Preferably, a bearing seat is fixedly connected to the outer wall of the hull, and the rotating shaft is fixedly inserted into the bearing inner hole on the bearing seat.
[0010] By adopting the above technical solution, the shaft is fixedly inserted into the bearing inner hole on the bearing seat, which makes the shaft more stable and smooth when it is rotated and connected to the outer wall of the ship's hull.
[0011] Preferably, a support pipe is fixedly connected to the outer wall of the hull, the axis of the support pipe is perpendicular to the outer wall of the hull, a movable rod is coaxially slidably inserted into the support pipe, a bearing seat is coaxially fixedly connected to the end of the movable rod away from the support pipe, and the support pipe is provided with an adjusting component to adjust the sliding position of the movable rod.
[0012] By adopting the above technical solution and setting the sliding position of the adjusting rod, the position of the detection rod relative to the hull can be adjusted, so that the detection rod can be in a more suitable detection position.
[0013] Preferably, the movable rod is a threaded rod, and the adjusting component is an adjusting sleeve that is coaxially rotatably connected to the support tube, with the movable rod threaded through the adjusting sleeve.
[0014] By adopting the above technical solution, the sliding position of the movable rod can be precisely adjusted by rotating the adjusting screw sleeve, thereby adjusting the position of the probe rod.
[0015] Preferably, the outer peripheral wall of the probe rod has a limiting hole, and multiple limiting holes are provided and distributed at intervals along the axial direction of the probe rod. The mounting sleeve is threaded through the limiting bolt, and the threaded end of the limiting bolt is inserted into the limiting hole.
[0016] By adopting the above technical solution, the position of the probe rod in the mounting sleeve can be adjusted according to actual needs, and the probe rod can be fixed by inserting the limiting bolt into the limiting hole at different positions, so as to achieve flexible adjustment of the installation height of the probe rod.
[0017] Preferably, the lower end of the detection rod is equipped with a funnel-shaped protective cover with an opening at the bottom. A detector is installed at the lower end of the detection rod and is housed within the protective cover.
[0018] By adopting the above technical solution, the detector is built into the protective cover and fixedly connected to the detection rod, which can protect the detector during depth measurement operations.
[0019] In summary, this utility model has the following beneficial effects:
[0020] 1. When the lower part of the detection rod encounters a net, the ship continues to move forward. The lower part of the detection rod is pulled and tends to swing around the axis of rotation towards the rear of the hull. The upper part of the detection rod is subjected to force around the axis of rotation towards the front. When the force reaches its upper limit, the pin damaged by the external force will be crushed by the detection rod, thus causing the detection rod to rotate around the axis of rotation. This allows the detection rod to get rid of the obstacle and reduces the possibility of bending deformation. After the detection rod gets rid of the obstacle, it will rotate back to its original position, and the pin damaged by the external force will be replaced to continue the detection operation.
[0021] 2. Setting two externally damaged pins can keep the probe rod in a vertical position under normal conditions;
[0022] 3. The detector is built into a protective cover and fixedly connected to the detection rod, which can protect the detector during depth measurement operations. Attached Figure Description

[0029] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.
[0030] Example 1:
[0031] This application discloses a fixed-installation anti-trailing bracket for ships, referring to... Figure 1The system includes a hull 1 and a detection rod 2. A mounting bracket 3 is fixedly connected to the hull side 11, and a connecting horizontal plate 12 is fixedly connected to the upper inner side wall of the hull side 11. The mounting bracket 3 includes a mounting vertical plate 31 fixedly connected to the outer side wall of the hull side 11 and a mounting horizontal plate 32 fixedly connected to the connecting horizontal plate 12. The mounting vertical plate 31 and the mounting horizontal plate 32 are respectively installed on the mounting vertical plate 31 and the mounting horizontal plate 32 by screw and nut pairs.
[0032] A support arm 4 is fixedly connected to the outer wall of the mounting vertical plate 31. The support arm 4 is horizontally positioned. A bearing seat 41 is fixedly connected to the end of the support arm 4 away from the mounting vertical plate 31. A rotating shaft 42 is coaxially rotatably connected to the bearing seat 41. Specifically, the rotating shaft 42 is fixedly inserted into the bearing inner hole on the bearing seat 41, and the axis of the rotating shaft 42 is perpendicular to the surface of the mounting vertical plate 31. A mounting sleeve 43 is fixedly connected to the end of the rotating shaft 42 away from the bearing seat 41, and the axis of the mounting sleeve 43 is perpendicular to the axis of the rotating shaft 42.
[0033] Reference Figure 1 , Figure 2 The probe rod 2 slides through the mounting sleeve 43. In this embodiment, the outer peripheral wall of the probe rod 2 has multiple limiting holes 23, which are spaced apart along the axial direction of the probe rod 2. A limiting bolt 44 is threaded through the outer wall of the mounting sleeve 43, and the threaded end of the limiting bolt 44 is inserted into the limiting hole 23. A funnel-shaped protective cover 21 is installed at the lower part of the probe rod 2. The lower part of the protective cover 21 is open and flared. A detector 22 is installed at the lower end of the probe rod 2, and the detector 22 is built into the protective cover 21.
[0034] Reference Figure 1 , Figure 3 A connecting seat 33 is fixedly connected to the upper outer wall of the mounting plate 31. The connecting seat 33 is located above the rotating shaft 42. The connecting seat 33 is detachably connected to an external force damage pin 34. Specifically, the external force damage pin 34 is a plastic tube, and there are two external force damage pins 34, which abut against the upper two side walls of the probe rod 2 respectively. In this embodiment, the connecting seat 33 has an insertion hole for inserting the external force damage pin 34, and a set screw 35 is threaded to the upper end face of the connecting seat 33, which abuts against the outer wall of the external force damage pin 34.
[0035] The implementation principle of a fixed-installation anti-tethering bracket for ships according to an embodiment of this application is as follows: Under normal conditions, two externally damaged pins 34 abut against the upper side walls of the detection rod 2, keeping the detection rod 2 vertical for topographic surveying operations; when the lower part of the detection rod 2 encounters a net, the ship continues to move forward, and the lower part of the detection rod 2 is pulled and tends to swing towards the rear of the hull 1 around the pivot 42. The upper part of the detection rod 2 applies a force to the front side around the pivot 42. When the externally damaged pin 34 located at the front reaches the upper limit of the force, it will be crushed by the detection rod 2, thereby causing the detection rod 2 to rotate around the pivot 42, allowing the detection rod 2 to get rid of the obstacle and reducing the possibility of bending deformation of the detection rod 2; after the detection rod 2 gets rid of the obstacle, it rotates back to its original position, and the externally damaged pin 34 is replaced to continue the detection operation.
[0036] Example 2:
[0037] The difference from Example 1 is that, referring to Figure 4 The support arm 4 includes a support tube 45 fixedly connected to the outer wall of the mounting vertical plate 31 and a movable rod 46 slidably inserted into the support tube 45. A bearing seat 41 is coaxially fixedly connected to the end of the movable rod 46 away from the support tube 45. The support tube 45 is provided with an adjusting element for adjusting the sliding position of the movable rod 46. In this embodiment, the movable rod 46 is a threaded rod, and the adjusting element is an adjusting sleeve 47 coaxially rotatably connected to the support tube 45. The movable rod 46 is threaded through the adjusting sleeve 47. The sliding position of the movable rod 46 can be precisely adjusted by rotating the adjusting sleeve 47, thereby adjusting the position of the probe 2.
[0038] Example 3:
[0039] The difference from Example 1 is that, referring to Figure 5 The external force damage pin 34 is a plastic tube. The middle part of the external force damage pin 34 has notches 341 on both sides, so that the middle part of the external force damage pin 34 forms a fragile part, so that the external force damage pin 34 will break from the fragile part after the force reaches the upper limit.
[0040] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
