Description

Technical Field

[0001] This application relates to the field of surveying and mapping technology, and in particular to a combined fixed support for surveying ships. Background Technology

[0002] A depth sounder is an instrument that uses sound waves to detect water depth. The transmission and reception of sound waves are achieved through a transducer. In use, the transducer is typically placed in the water, and then it emits sound waves underwater to detect the water depth. The detection result is then fed back to the instrument, while simultaneously transmitting a position signal to the outside world via a signal line.

[0003] In existing methods, a fixed cylinder is usually used to fix the transducer wiring. That is, the transducer wiring is passed through the fixed cylinder and the transducer is installed at the end of the fixed cylinder to ensure the stability of the transducer.

[0004] However, in existing technologies, the fixing cylinder is usually secured by hanging ropes. The hanging ropes are passed through the loops on both sides of the lower end of the fixing cylinder and then fixed to the ship's side to secure the fixing cylinder. This method of securing the fixing cylinder requires the cooperation of multiple people and is relatively time-consuming. Utility Model Content

[0005] To increase the ease of installation of the fixed cylinder, this application provides a combined fixed bracket for surveying ships.

[0006] This application provides a combined fixed support for a surveying vessel, which adopts the following technical solution: A combined fixed support for a surveying vessel, characterized in that: it includes a fixed seat connected to the ship's side, a rotating mechanism is rotatably provided on the fixed seat, a fixed cylinder for passing through transducer wiring is provided on the rotating mechanism, and a limiting mechanism is provided on the fixed cylinder to prevent the fixed cylinder from sliding down.

[0007] By adopting the above technical solution, the rotating mechanism is rotated to extend one end out of the ship's side, the transducer wiring is threaded into the fixed cylinder, and the transducer wiring and the fixed cylinder are threaded into the rotating mechanism together. Then, the fixed cylinder is limited by the limiting mechanism, and the installation of the fixed cylinder is completed.

[0008] Preferably, the rotating mechanism includes a fixed ring disposed on a fixed base, a triangular bracket rotatably disposed on the fixed ring, and a sleeve ring disposed at the end of the triangular bracket away from the fixed ring, with the fixed cylinder passing through the sleeve ring.

[0009] By adopting the above technical solution, the fixing ring allows the triangular bracket to rotate flexibly, thereby driving the fixed cylinder to rotate together. The triangular bracket increases the stability of the sleeve ring passing through the fixed cylinder. The sleeve ring is used to sleeve the fixed cylinder and install the fixed cylinder on the rotating mechanism.

[0010] Preferably, the limiting mechanism includes a rotating bracket rotatably mounted on the ship's side and a snap ring fixed on the rotating bracket. The fixed cylinder has an annular groove, and the snap ring engages with the annular groove. A positioning element for positioning the rotating bracket is provided on the ship's side.

[0011] By adopting the above technical solution, the positioning component is used to limit the position of the rotating bracket in the horizontal direction, the rotating bracket is used to fix the snap ring, the snap ring and the ring groove are engaged to fix the fixed cylinder in the vertical direction to prevent the fixed cylinder from sliding down. When the fixed cylinder is removed, the positioning component is used to fix the position of the rotating bracket in the vertical direction to prevent the rotating bracket from hitting the hull.

[0012] Preferably, the fixed cylinder is detachably connected with an abutment bolt, which is used to abut the sleeve ring.

[0013] By adopting the above technical solution, the upper abutting bolt set on the fixed cylinder abuts against the sleeve ring, thereby preventing the fixed cylinder from sliding upward and limiting the position of the fixed cylinder.

[0014] Preferably, the fixed cylinder includes a plurality of coaxially arranged connecting cylinders, one end of which is provided with a threaded connection part, and the other end is provided with a threaded connection hole for threaded connection of the threaded connection part.

[0015] By adopting the above technical solution, multiple connecting cylinders are connected by threads, which facilitates the disassembly and storage of the fixed cylinder and saves storage space.

[0016] Preferably, the positioning element includes a mounting base fixed to the ship's side and a positioning pin disposed on the mounting base for abutting against the rotating bracket, the rotating bracket being rotatably connected to the mounting base.

[0017] By adopting the above technical solution, the positioning pin is used to abut against the rotating bracket to position the rotating bracket, ensuring that the snap ring can engage with the annular groove, thus ensuring the stability of the fixed cylinder installation. At the same time, when the rotating bracket rotates close to the ship's side, the positioning pin can be used to fix the rotating bracket to the ship's side.

[0018] Preferably, the fixed cylinder is provided with an anti-slip rubber ring.

[0019] By adopting the above technical solution, the anti-slip rubber ring increases the friction between the operator's hand and the gripping part of the fixed cylinder, making it easier to assemble and disassemble the fixed cylinder.

[0020] Preferably, the fixed cylinder is provided with a threaded connector, which is used to install signal lines.

[0021] By adopting the above technical solution, the threaded connector makes it easy to install the signal line on the fixed cylinder, which is beneficial to signal output and reception.

[0022] In summary, this application includes at least one of the following beneficial technical effects: 1. In this application, the rotating mechanism is rotated to extend one end out of the ship's side, the transducer wiring is threaded into the fixed cylinder, and the transducer wiring and the fixed cylinder are threaded into the rotating mechanism together. Then, the fixed cylinder is limited by the limiting mechanism, and the installation of the fixed cylinder is completed. 2. The fixing ring of this application allows the triangular bracket to rotate flexibly, thereby driving the fixed cylinder to rotate together. The triangular bracket increases the stability of the sleeve ring passing through the fixed cylinder. The sleeve ring is used to sleeve the fixed cylinder and install the fixed cylinder on the rotating mechanism. 3. The positioning component of this application is used to limit the position of the rotating bracket in the horizontal direction. The rotating bracket is used to fix the snap ring. The snap ring engages with the annular groove to fix the fixed cylinder in the vertical direction, preventing the fixed cylinder from sliding down. When the fixed cylinder is removed, the positioning component is used to fix the position of the rotating bracket in the vertical direction, preventing the rotating bracket from hitting the hull.

[0025] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0026] Embodiment 1 of this application discloses a combined fixed bracket for surveying ships.

[0027] Example 1: Reference Figure 1 and Figure 2 A modular fixed support for a surveying vessel includes a fixed base 1, which is detachably fixed to the ship's side by bolts. A rotating mechanism 2 is rotatably mounted on the fixed base 1. The rotating mechanism 2 includes a fixed ring 21, a triangular bracket 22, and a sleeve ring 23. The fixed ring 21 is integrally formed with the fixed base 1 by welding. The triangular bracket 22 is rotatably mounted on the fixed ring 21. Specifically, the triangular bracket 22 consists of a rotating rod and two connecting rods. The rotating rod can rotate within the fixed ring 21, and each end of the rotating rod is connected to a connecting rod. The three components combine to form a triangular frame structure. A sleeve ring 23 is provided at the connection point of the two connecting rods. A fixed cylinder 3 passes through the sleeve ring 23. The fixed cylinder 3 is equipped with a limiting mechanism 4 to prevent it from sliding down. In use, the fixed cylinder 3 is used to thread transducer wiring. Reference Figure 1 and Figure 2 In actual operation, when surveying is required, the triangular bracket 22 is rotated around the fixing ring 21 toward the outside of the ship's side, so that part of the triangular bracket 22 overlaps above the ship's side and the other part is suspended outside the ship's side. Then, the fixing cylinder 3 is passed through the sleeve ring 23 and the fixing cylinder 3 is limited by the limiting mechanism 4 to prevent the fixing cylinder 3 from sliding down. After the surveying work is completed, the fixing cylinder 3 is removed first, and then the triangular bracket 22 is rotated until it is completely overlapped on the ship's side.

[0028] Reference Figure 1 and Figure 2 To facilitate the assembly of the fixed cylinder 3 and the transducer, the fixed cylinder 3 is assembled from multiple connecting cylinders 31. In this embodiment, the number of connecting cylinders 31 is set to 2, and they are named the first connecting cylinder 311 and the second connecting cylinder 312 respectively. One end of the first connecting cylinder 311 is provided with a threaded connection part 8, and the other end is provided with a threaded connection hole 9. A threaded connector 200 is threadedly connected in the threaded connection hole 9. The threaded connector 200 is used to install the RTK signal line, thereby transmitting position information outward. Compared with the existing method of installing the RTK signal line on the hull, the installation position of the RTK in this application is higher, and the signal strength is relatively more stable.

[0029] Reference Figure 1 and Figure 2A groove 300 is provided at the edge of the threaded connection hole 9 for passing the transducer wiring through the first connecting cylinder 311. At the same time, a threaded connection hole 9 is also provided at one end of the second connecting cylinder 312. The threaded connection part 8 of the first connecting cylinder 311 is threadedly engaged with the threaded connection hole 9 of the second connecting cylinder 312. An abutment bolt 7 is threadedly connected to the first connecting cylinder 311 near the sleeve ring 23. The abutment bolt 7 is threadedly connected to the first connecting cylinder 311 and is located below the sleeve ring 23 to prevent the first connecting cylinder 311 from sliding upward after installation.

[0030] Reference Figure 1 and Figure 2 The limiting mechanism 4 is located below the rotating mechanism 2, and the limiting mechanism 4 is used to work with the rotating mechanism 2 to fix the fixed cylinder 3. The limiting mechanism 4 includes a rotating bracket 41 and a snap ring 42. The lower end of the second connecting cylinder 312 is provided with an annular groove 5. The rotating bracket 41 is rotatably mounted on the ship's side. The snap ring 42 is provided on the rotating bracket 41. The size of the snap ring 42 is larger than the size of the second connecting cylinder 312 at the location where the annular groove 5 is located and smaller than the size of the second connecting cylinder 312 excluding the annular groove 5. That is, the snap ring 42 is snapped into the annular groove 5 to prevent the fixed cylinder 3 from sliding down. In this embodiment, the snap ring 42 is preferably a clamp.

[0031] Reference Figure 1 and Figure 2 To limit the installation position of the fixed cylinder 3, the operator passes the connecting cylinder 31 through the sleeve ring 23 and then through the snap ring 42, so that the snap ring 42 abuts against the upper side wall of the ring groove 5, thereby preventing the fixed cylinder 3 from sliding down. By screwing the abutting bolt 7 into the first connecting cylinder 311, the fixed cylinder 3 can be limited, preventing the fixed cylinder 3 from sliding up during the operation of the surveying vessel, thus increasing the stability of the installation of the fixed cylinder 3.

[0032] Reference Figure 1 and Figure 2 A positioning component 6 is provided on the ship's side. The positioning component 6 is used to position the rotating bracket 41. The positioning component 6 includes a mounting base 61 and a positioning pin 62. The mounting base 61 is bolted to the ship's side. One end of the rotating bracket 41 is rotatably connected to the mounting base 61. The mounting base 61 is provided with a positioning pin 62 and a positioning hole 63 through which the positioning pin 62 can pass. When the rotating bracket 41 is rotated to the horizontal position, the positioning pin 62 is combined with the positioning hole 63. At this time, the positioning pin 62 is located below the rotating bracket 41. When the rotating bracket 41 is rotated to the vertical position, the positioning pin 62 is combined with the positioning hole 63. At this time, the distance between the positioning pin 62 and the ship's side is slightly greater than the distance between the rotating bracket 41 and the ship's side and is close to the rotating bracket 41.

[0033] Reference Figure 1 and Figure 2To limit the position of the rotating bracket 41, during actual operation, the operator first rotates the rotating bracket 41 to a horizontal position, and then inserts the positioning pin 62 into the positioning hole 63. At this time, the positioning pin 62 provides an upward support force for the rotating bracket 41, preventing the rotating bracket 41 from rotating downward, thus providing good support for the connecting cylinder 31. After removing the fixed cylinder 3, the positioning pin 62 is removed. When the rotating bracket 41 is rotated to a vertical position along the direction close to the ship's side, the positioning pin 62 is inserted into the positioning hole 63 to fix the rotating bracket 41 to the ship's side, preventing the rotating bracket 41 from shaking significantly during the operation of the surveying vessel, thereby colliding with the ship's side and causing damage to the ship's side.

[0034] The implementation principle of Embodiment 1 of this application is as follows: When it is necessary to install the fixed cylinder 3, rotate the triangular bracket 22 to rotate it around the fixing ring 21 towards the outside of the ship's side, and then insert the fixed cylinder 3 into the snap ring 42 to complete the installation of the fixed cylinder 3; when it is necessary to remove the fixed cylinder 3, first pull the abutting bolt 7 out of the first connecting cylinder 311, then lift the fixed cylinder 3 upward so that the second connecting cylinder 312 disengages from the snap ring 42, rotate the triangular bracket 22 to rotate it along the fixing ring 21 towards the ship's side, and then disengage the fixed cylinder 3 from the sleeve ring 23, and finally the fixed cylinder 3 can be removed; when it is necessary to store the fixed cylinder 3, hold the anti-slip rubber ring 100 and unscrew the fixed cylinder 3 to separate it into the first connecting cylinder 311 and the second connecting cylinder 312, which shortens the original length of the fixed cylinder 3 after installation, making it easier to store the fixed cylinder 3 and saving storage space.

[0035] Example 2: Reference Figure 3 and Figure 4 The difference between this embodiment and embodiment 1 is that a first guide rod 400 is rotatably mounted on the triangular bracket 22. The end of the first guide rod 400 away from the ship's side is fixedly connected to the sleeve ring 23. A fixing bolt 800 is provided on the first guide rod 400 to fix the first guide rod 400. The sleeve ring 23 rotates along the length of the ship's side, thereby driving the fixed cylinder 3 to rotate together. Correspondingly, in order to improve the stability of the rotation of the fixed cylinder 3, a second guide rod 500 is fixedly mounted on the snap ring 42. An arc-shaped block 600 is provided at the end of the rotating bracket 41 away from the ship's side. A guide groove 700 is opened on the arc-shaped block 600. The center of the guide groove 700 coincides with the axis of the first guide rod 400. After one end of the second guide rod 500 passes through the guide groove 700, it is locked by a fixing nut 900.

[0036] The implementation principle of Embodiment 2 of this application is as follows: Since the fixed cylinder 3 needs to be submerged underwater, it is inevitably deformed due to prolonged water erosion, which will cause the transducer wiring to deflect. In order to keep the transducer in a vertical position, the direction of the fixed cylinder 3 is adjusted. During the adjustment process, the sleeve ring 23 rotates with the rotation of the first guide rod 400. During the rotation, the snap ring 42 rotates and drives the second guide rod 500 to rotate along the guide groove 700. When the fixed cylinder 3 is adjusted to make the transducer vertical, the fixing bolt 800 is rotated to press against the first guide rod 400, and the fixing nut 900 locks the second guide rod 500 to prevent the second guide rod 500 from disengaging from the guide groove 700.

[0037] 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.
