Description

Technical Field

[0001] This utility model relates to the field of underwater topographic exploration, and in particular to a shipborne depth sounder fixation device with a fixed draft. Background Technology

[0002] One of the important tasks of basic water resources surveys is to investigate water storage, which involves underwater topographic (depth) measurements of lakes, reservoirs, ponds, rivers, and oceans. Underwater topographic data acquisition is primarily accomplished using single-beam and multi-beam bathymetry techniques. A single / multi-beam bathymetry instrument, used for underwater topographic surveying, includes a transducer, operating computer, a sounding rod, and connecting cables, and works in conjunction with a location-based kinematic (RTK) instrument. During measurement, the transducer is submerged in water, connected to the RTK via a steel pipe sounding rod using connecting cables, and then connected to the operating computer.

[0003] Typically, the sounding rod is fixed at the center of the vessel or at 1 / 3 to 2 / 3 of the hull, and the transducer must be rigidly connected to the sounding rod. When installing the transducer, its bottom surface should be kept as parallel to the water surface as possible. After submersion, the transducer's draft should be taken into account; the submersion depth of the sounding transducer is the distance from the water surface to the bottom of the transducer. When performing depth measurements, a transducer draft correction must be performed. This value can be set in the sounding's draft parameters during depth measurement, or it can be corrected based on the recorded draft parameters.

[0004] Common methods for securing depth sounders include rope connections or binding with anchors. Daily installation of the depth sounder transducer and sounding rod causes variations in its draft; repeated installations affect accuracy. Furthermore, disassembling the sounding rod before and after each measurement is time-consuming and labor-intensive, reducing work efficiency.

[0005] Currently, Chinese patent application publication 202321486174.4 discloses a depth sounder fixing device, including a single-beam depth sounder and a fixing base. The fixing base is fixed to the hull by threads. The single-beam depth sounder is fixed by a combination of an identification component, an adjustment component, and a clamping component. However, in this document, although the single-beam depth sounder transducer can be fixed to the hull, the depth sounding rod needs to be installed on the ship's side and the draft measured every day when boarding the ship. At the end of each day's measurement, the fixing device needs to be disassembled to remove the transducer from the water. This results in the draft constantly changing and requiring repeated measurements. In addition, the daily installation and disassembly consume a lot of time and effort.

[0006] In summary, when measuring the capacity of surface water (lakes, rivers, reservoirs, and ponds, etc.) in the field, a single-beam echo sounder must be fixed to a vessel and measured along the sounding lines. However, current echo sounder mounting systems have the following issues that need improvement:

[0007] (1) Repeated installation every day leads to inconsistent draft depth.

[0008] (2) Installation and disassembly are difficult and time-consuming.

[0009] Therefore, how to provide a fixture that is easy to install and does not require repeated installation of the depth sounder transducer and depth sounding rod has become an urgent problem to be solved. Utility Model Content

[0010] This utility model provides a marine depth sounder fixing device for fixing the draft, which solves the problem that when using existing fixing devices, the depth sounding rod and transducer must be reinstalled every time a measurement is taken, resulting in deviations in the position of the depth sounding rod and thus deviations in the draft of the transducer.

[0011] To achieve the above objectives, this utility model provides a marine depth sounder fixing device for fixing draft, characterized in that it comprises: a fixed base, an adjusting assembly, and a flip-up mounting plate. The fixed base is C-shaped, including two vertical plates, one long and one short, and a horizontal plate; the adjusting assembly consists of a circular double-ended tube socket and a pin, the circular double-ended tube socket being located on one side of the upper surface of the horizontal plate, and the circular double-ended tube socket being rotatably connected to the flip-up mounting plate via the pin. Loosening the pin allows the flip-up mounting plate on the fixed base to rotate around the horizontal plate about the adjusting assembly as an axis.

[0012] As a preferred embodiment of the above technical solution, preferably, during measurement, the flip-up mounting plate is attached to the longer vertical plate.

[0013] As a preferred embodiment of the above technical solution, the fixed base is fixed to the stern of the hull, and the two vertical plates are respectively close to the inner and outer sides of the hull, with the shorter vertical plate located inside the hull.

[0014] As a preferred embodiment of the above technical solution, preferably, the edge of the transverse plate near the outer side of the vessel is parallel to the side plate of the vessel, and the circular double-ended tube socket is provided therein.

[0015] As a preferred embodiment of the above technical solution, the pin has a round cap at one end and a thread at the other end, and is inserted into the tubular structure formed by the round double-ended tube socket and the flip-up mounting plate.

[0016] As a preferred embodiment of the above technical solution, preferably, the outer diameter of the circular cover is larger than the outer diameter of the tubular structure.

[0017] As a preferred embodiment of the above technical solution, the bottom end of the longer vertical plate has a protruding fixing plate with positioning holes, and the depth measuring rod is fixed to the bottom end of the longer vertical plate by a fixing assembly.

[0018] As a preferred embodiment of the above technical solution, preferably, the flip-up mounting plate is located at the top of the longer vertical plate, and the depth measuring rod is fixed to the top of the longer vertical plate by a fixing assembly, thereby fixing the depth measuring rod to the fixing base.

[0019] This utility model provides a marine depth sounder fixing device for fixing draft. The fixing base is C-shaped and includes two vertical plates, one long and one short, and a horizontal plate. The adjusting component consists of a circular double-ended tube socket and a pin. The circular double-ended tube socket is located on one side of the upper surface of the horizontal plate, and the circular double-ended tube socket is rotatably connected to the flip-up mounting plate through the pin. When the pin is loosened, the flip-up mounting plate rotates around the horizontal plate with the adjusting component as the axis.

[0020] The advantage of this invention is that it solves the problem mentioned in the prior art where operators need to constantly install and remove the depth measuring rod before and after operation, and the repeated installation is affected by changes in draft, which reduces the efficiency and accuracy of the operation.

[0025] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0026] First, the structure of this utility model will be described, such as... Figure 1 As shown, it includes a C-shaped fixed base, an adjustment component, and a flip-up mounting plate 6.

[0027] The fixed base is U-shaped and includes a horizontal plate 1, a long vertical plate 2, and a short vertical plate 3. The adjustment assembly is installed on the upper surface of the horizontal plate 1. The flip-up mounting plate 6 is rotatably connected to the adjustment assembly.

[0028] The flip-up mounting plate 6 has a sleeve that matches the adjustment component.

[0029] The adjustment assembly consists of a circular double-ended tubular socket 4 and a pin 5. The circular double-ended tubular socket 4 is located on one side of the upper surface of the horizontal plate 1, and is rotatably connected to the flip-up mounting plate 6 via the pin 5. One end of the pin 5 has a round cap, and the other end has threads. It is rotatably inserted into the tubular structure formed by the engagement of the circular double-ended tubular socket 4 and the flip-up mounting plate 6. The outer diameter of the round cap of the pin 5 is larger than the outer diameter of the tubular structure, allowing the pin 5 to fix the flip-up mounting plate 6 to the circular double-ended tubular socket 4. The flip-up mounting plate has bolts 9, which are used to fix the top of the depth measuring rod to the fixing assembly 8. The bottom of the longer vertical plate has a protruding fixing plate 7, which has bolts 9 on it. The bottom of the fixing plate is fixed to the fixing base via the fixing assembly 8.

[0030] The fixed base is fixed to the stern of the hull. The two vertical plates are close to the inner and outer sides of the hull respectively. The shorter vertical plate is located inside the hull. The horizontal plate 1 is parallel to the side plate of the hull near the outer edge of the hull. A circular double-ended tube socket 4 is installed on it.

[0031] During measurement, the flip-up mounting plate 6 is attached to the long vertical plate 2, and the single-beam connecting rod vertically connects to the transducer below it.

[0032] Loosen the bottom fixing component 8, loosen the pin 5, flip the flip-up mounting plate 6, and the depth sounding rod and transducer rotate with the flip-up mounting plate. They rotate around the transverse plate 1 with the pin 5 in the adjusting component as the axis, so that the single-beam depth sounding rod vertical transducer can be flipped and lifted out of the water without disassembling the depth sounding rod.

[0033] The technical solution of this utility model is now described with reference to a specific embodiment, such as... Figures 1 to 3 As shown.

[0034] After placing the mounting base at the stern of the hull, secure it with bolts and threads.

[0035] Specifically, the horizontal plate 1 spans across the stern of the ship's side plate, and the two vertical plates are close to the inner and outer sides of the ship's interior. The outer vertical iron plate is fixed with screws through six positioning holes, while the inner iron plate is shorter and is fixed to the inner side of the ship's side with screws through four positioning holes. It is then tightened inwards by screws on both sides to fix it to the ship's side.

[0036] Two circular double-ended tube sockets 4 are installed parallel to the outer edge of the ship's side plate near the outer edge of the transverse plate 1. The circular double-ended tube sockets 4 are connected to the flip-up mounting plate 6 via pins 5.

[0037] The flip-page mounting plate 6 is connected to the fixed base via an adjustment component.

[0038] Specifically, the sleeve of the flip-up mounting plate 6 is placed between the circular double-ended sleeve socket 4 to form a complete tube body. Then, the pin 5 is inserted into this tube body. One end of the pin 5 is provided with a round cap, and the other end of the pin 5 is threaded. The thread matches the inner wall of this tube body. After the pin 5 is nested through the horizontal plate 1 and the circular double-ended sleeve of the flip-up mounting plate 6, the nut is tightened along the thread at one end.

[0039] The flip-up mounting plate 6 has bolts 9, which are used to fix the top of the depth measuring rod through the fixing assembly 8. The fixing assembly 8 is provided at both the upper and lower ends of the long vertical plate 2. The upper fixing assembly 8 is connected to the flip-up mounting plate 6, and the lower fixing assembly 8 is connected to the protruding fixing plate 7, thereby fixing the probe rod to the fixing base.

[0040] The bottom of the longer vertical plate has a protruding fixing plate 7 with two positioning holes. The bottom of the depth measuring rod is fixed to the fixing base by an iron sheet (the aforementioned fixing component 8). The diameter of the iron sheet is the same as that of the depth measuring rod.

[0041] Specifically, the probe rod is placed between each bolt 9, and then an iron plate is placed on top of it and secured with a nut, thereby fixing the probe rod in place with the bolts 9. The positioning and setting-out instrument (RTK) and the transducer are respectively fixed at the upper and lower ends of the sounding rod.

[0042] In use, connect the transducer and RTK to the bottom and top of the sounding rod, install the fixed base on the ship's side, tighten the pin 5, fix the flip-up mounting plate to the vertical plate 2, place the sounding rod between the bolts 9 on the flip-up mounting plate 6 and the fixed plate 7 and adjust the length. After adjustment, fix it with the fixing component 8 to fix the sounding rod for measurement.

[0043] When a measurement is completed, loosen the fixing component 8 (the fixing device can be the bolt 9 in the figure) on the bottom protruding fixing plate 7 of the vertical plate 2, loosen the pin 5, and rotate the pin 5 to flip the flip-up mounting plate 6 from being attached to the outer vertical iron plate to being horizontal with the horizontal plate 1. The transducer can then be taken out of the water surface without removing the fixing device and the depth measuring rod. Since the top of the depth measuring rod is still fixed to the flip-up mounting plate, the installation and disassembly time is greatly saved while ensuring that the draft of the transducer is not changed.

[0044] In summary, this utility model provides a shipboard fixing device for the sounding rod of a single-beam echo sounder transducer, solving the problems mentioned in the prior art where operators need to constantly install and remove the sounding rod before and after operation, as well as the repeated installation and removal due to changes in draft, which reduces operational efficiency and accuracy.

[0045] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
