Description

Technical Field

[0001] This utility model relates to the field of engineering surveying technology, and in particular to a towed floating platform for measuring water depth alongside a stone-throwing vessel. Background Technology

[0002] Riverbank protection projects are crucial to the safety of dikes and the navigation of waterways, and are a key focus of inland river management and water conservancy construction. Inland river riprap revetment is an economical and environmentally friendly method. The riprap used is quarried stone, which is heavy and has good resistance to flood erosion. Considering the water depth of inland rivers, 1000-2000 ton bulk carriers are generally used to transport the stones. Excavators are then used to load the stones onto the ship. Typically, the excavator loads the stones 0.5-2.5 meters outside the ship's hull. Considering the impact of drift, the riprap loading area extends from 1 meter inside the ship's hull to 4 meters outside. Water depth measurements are required before and after riprap loading.

[0003] Traditional methods of measuring water depth using boulders are inaccurate, highly susceptible to current fluctuations, and difficult to measure the main rockfall areas 0.5-2.5m beyond the ship's hull. Using survey vessels for water depth measurement interferes with rock-dropping operations, resulting in poor timeliness and limited on-site guidance for the operation. Currently, the main platforms for measurement operations are motorized boats and unmanned vessels, driven by diesel generators or electric motors. Motorized boats offer the advantage of minimal swaying, but suffer from drawbacks such as large draft, high fuel consumption, and large turning radius. Small unmanned vessels are compact, but exhibit significant swaying, and the technology for tilt correction needs improvement. Utility Model Content

[0004] The purpose of this invention is to solve the problems existing in the prior art by proposing a towed floating platform for measuring water depth alongside a stone-throwing vessel.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A towed floating platform for measuring water depth alongside a quarry, comprising a float and further comprising:

[0007] An outer frame, which is square and covers the outside of the float;

[0008] And a steel pipe fence, which is fixed to the top of the outer frame, and the steel pipe fence and the top of the float form a working space;

[0009] The outer frame is fixed with an instrument bracket for placing a depth sounding instrument on one side, and the outer frame is provided with pull ropes at both ends of one side of the instrument bracket.

[0010] Preferably, the float comprises a foam body and an iron shell covering the outside of the foam body, and the dimensions of the float are 2000mm in length, 2000mm in width, and 300mm in thickness.

[0011] Preferably, the outer frame includes an upper frame and a lower frame welded from angle steel, with connecting angle steel provided between the upper frame and the lower frame, and a first baffle provided on both the upper frame and the lower frame.

[0012] Preferably, a second baffle is also fixed on the upper frame, and a wooden board is placed between the second baffle and the first baffle, the wooden board serving as a support surface for the workspace.

[0013] Preferably, the depth sounding instrument on the instrument bracket is positioned at one-third of the position on the side of the outer frame, and the width of the instrument bracket is 500mm.

[0014] Preferably, the outer frame is also fixed with an adjustment rod for adjusting the distance between the float and the hull, and the distance adjustment range is 0-1500mm.

[0015] Compared with the prior art, this utility model provides a towed floating platform for measuring water depth alongside a stone-dropping vessel, which has the following advantages:

[0016] 1. This towed floating platform used for measuring water depth alongside rock-dropping vessels is moved by towing ropes, giving the platform a certain degree of mobility. Water depth measurements are taken before and after rock-dropping on the revetment to promptly detect any under-dropping or over-dropping situations, reducing the need for rework due to under-dropping or excavation due to over-dropping, and significantly improving the construction quality and efficiency of rock-dropping projects.

[0017] 2. This towed floating platform for measuring water depth alongside a stone-dropping vessel mounts a depth sounding instrument on an instrument bracket on the side of the platform, with a distance of 0.5m from one sideline and 1.5m from the other sideline. The platform is also equipped with an adjustable rod that can extend 1.5m, allowing the instrument's measurement position to be adjusted between 0.5m, 1.5m, 2.5m, and 3.5m. This enables measurements to be taken at 1m intervals, achieving an effect similar to multibeam bath measurement and improving measurement efficiency.

[0018] 3. The towed floating platform used for measuring water depth alongside the stone-throwing vessel has a sheet metal shell and outer frame installed on the outside of the foam body to prevent damage to the foam body during transportation and construction, thus ensuring its service life.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0025] In the description of this utility model, it should be noted that the terms "upper," "lower," "inner," "outer," "top / bottom," etc., indicating the orientation or positional relationship are based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0026] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed", "equipped with", "sleeved / connected", "connected", etc., should be interpreted broadly. For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. For those skilled in the art, the specific meaning of the above terms in this utility model can be understood according to the specific circumstances.

[0027] like Figures 1 to 4As shown, this embodiment proposes a towed floating platform for measuring water depth alongside a stone-throwing vessel. The platform includes a float 1, which comprises a foam body 101 and a sheet metal shell 102 covering the outside of the foam body 101 to provide stable buoyancy and prevent damage during transport. It also includes an outer frame 2 and a steel pipe enclosure 3. The outer frame 2 is square and covers the outside of the float 1 to ensure the stability of the platform structure. The float 1 has dimensions of 2000mm in length, 2000mm in width, and 300mm in thickness. The steel pipe enclosure 3 is fixed to the outer frame 2. The top of the steel pipe fence 3 and the top of the float 1 form a working space to ensure operational safety. Among them, an instrument bracket 4 for placing a depth sounding instrument is fixed on one side of the outer frame 2. The depth sounding instrument on the instrument bracket 4 is set at one-third of the position of the side of the outer frame 2, that is, 500mm from one edge and 1500mm from the other edge. The depth sounding instrument can be a single beam depth sounder. The instrument bracket 4 is 500mm wide to accommodate a variety of equipment. Pull ropes 5 are set at both ends of one side of the outer frame 2 and the instrument bracket 4.

[0028] In practice, the platform is launched from the shore and towed to the anchor position next to the rock-dropping vessel by a small boat. The operator adjusts the distance between the platform and the ship's side by pulling rope 5. The platform can be rotated by pulling only one side of the pulling rope 5, so that the distance between the platform and the ship's side can be adjusted within the range of 0.5m to 2m. This allows for the collection of water depth data from multiple survey lines, real-time observation of elevation changes before and after rock dropping, and guidance for the excavator to correct the rock dropping position. The manual towing of the platform can avoid conflicts with the rock dropping operation, giving the platform a certain degree of mobility, improving the real-time nature of construction, and timely detection of possible under-dropping or over-dropping situations. This reduces the occurrence of rework for under-dropping or over-dropping excavation, greatly improving the construction quality and efficiency of the rock dropping project. Moreover, the structure of foam float 1 + steel pipe fence 3 has low cost, requires no power drive, and reduces energy consumption and maintenance requirements.

[0029] It should be noted that, in order to further improve the depth measurement range of the platform, an adjustment rod 6 is also fixed on the outer frame 2 to adjust the distance between the platform and the hull, and the distance adjustment range is 0-1500mm. When it is necessary to measure the water depth at a position 3500mm away from the hull, the adjustment rod 6 is extended and abuts against the hull. The sum of the length of the adjustment rod 6 and the maximum distance of the platform width is 3.5m, so that the platform can measure four measurement lines at distances of 0.5m, 1.5m, 2.5m and 3.5m from the ship's side, achieving the effect of multi-beam measurement.

[0030] like Figure 1 , Figure 2 and Figure 3As shown, in a preferred embodiment, based on the above method, the outer frame 2 further includes an upper frame 201 and a lower frame 202 welded from angle steel. A connecting angle steel 203 is provided between the upper frame 201 and the lower frame 202. A first baffle 204 is provided on both the upper frame 201 and the lower frame 202. A double-layer frame structure is formed by welding angle steel. The upper frame 201 and the lower frame 202 are fixed by vertical connecting angle steel 203 to form a three-dimensional support system. The first baffle 204 is welded laterally to the inner side of the frame to enhance the torsional stiffness of the frame and limit the displacement of the float 1.

[0031] like Figure 1 , Figure 2 and Figure 3 As shown, in a preferred embodiment, based on the above method, a second baffle 205 is further fixed on the upper frame 201. A wooden board 206 is placed between the second baffle 205 and the first baffle 204. The wooden board 206 serves as a support surface for the workspace. The second baffle 205 and the first baffle 204 are welded parallel to each other at the upper frame 201 to form a sandwich space. The wooden board 206 is embedded therein as a detachable support surface. The wooden board 206 is made of anti-corrosion pine wood, and its size matches the inner distance of the frame. A 10mm expansion joint is reserved at the edge. The wooden board 206 serves as an operating table to bear the weight of the depth measuring instrument and personnel, and is limited by the baffle to prevent slippage.

[0032] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
