Description

Technical Field

[0001] This utility model relates to the field of underwater measurement technology, and in particular to an unmanned surface vessel for surveying. Background Technology

[0002] Small survey unmanned surface vessels (USVs) are used for underwater topographic surveying and mapping operations in lakes, rivers and other water bodies. The underwater survey module is the underwater survey equipment carried on the USV, which can include single-beam sonar depth sounders, side-scan sonar, ADCP, etc.

[0003] Patent document CN218181093U discloses "a surveying unmanned vessel," comprising a boom and a plug. A hanging cylinder is fixedly connected to the lower end of the boom. The plug is cylindrical in shape, and the hanging cylinder has an opening at the bottom for connecting with the plug. The plug and the hanging cylinder are rotatably and slidably connected through the opening. An elastic abutment structure is provided on the top surface of the opening. Two or more locking pins are evenly distributed on both sides of the plug, centered on their axis. A slot is provided on the outer wall of the hanging cylinder, slidingly connecting with the locking pins. The slot is inverted J-shaped with an opening at the bottom. The combination of the hanging cylinder, plug, elastic abutment structure, and slot facilitates rapid installation and disassembly of the detection units to the vessel hull. Each detection unit can be connected to its corresponding mounting plate, improving the compatibility of the mounting structure with surveying equipment.

[0004] While the device, through its structure including a hanging cylinder and a plug, facilitates the assembly and disassembly of the detection unit, its reliance on a single retaining rod elastically abutting within the slot results in poor stability. When the mounting plate sways due to water flow disturbances, it affects the stability of the retaining rod within the slot. Furthermore, the fixed structure of the boom makes height adjustment inconvenient, hindering its adaptability to different water depths and reducing operational flexibility. Therefore, it is necessary to provide a surveying unmanned vessel with a stable structure and adjustable operating depth to solve the aforementioned technical problems. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides a surveying unmanned vessel with a stable structure and adjustable operating depth.

[0006] The unmanned surface vessel for surveying provided by this utility model includes a hull, a moon pool compartment inside the hull, an adjustment mechanism inside the moon pool compartment, a connecting mechanism at the bottom of the adjustment mechanism, an installation mechanism at the bottom of the connecting mechanism, a detection unit at the bottom of the installation mechanism, and a fixing mechanism inside the connecting mechanism.

[0007] As provided by this utility model for an unmanned surface vessel for surveying, preferably, the adjustment mechanism includes a fixed sleeve, the fixed sleeve is fixed to the top of the inner cavity of the moon pool compartment, the inner cavity of the fixed sleeve is slidably connected to a fixed rod, the inner cavity of the fixed rod is provided with a fixed bolt, and the outer side of the fixed bolt is threaded with a fixed nut.

[0008] As a surveying unmanned vessel provided by this utility model, preferably, the adjustment mechanism further includes a fixed sleeve, a stabilizing block is fixedly connected to the outer side of the fixed sleeve, and a stabilizing rod is slidably connected to the inner cavity of the stabilizing block.

[0009] As provided by this utility model for providing an unmanned surface vessel for surveying, preferably, the connecting mechanism includes a connecting rod, a connecting sleeve slidably connected to the outer side of the connecting rod, the top of the connecting sleeve being fixedly connected to the bottom of a fixed rod, a docking block being fixedly connected to the top of the connecting rod, a docking seat being fixedly connected to the inner wall of the connecting sleeve, and the outer side of the docking block engaging with the inner cavity of the docking seat.

[0010] As provided by this utility model for an unmanned surface vessel for surveying, preferably, the installation mechanism includes an installation plate, the bottom of which is fixedly connected to the bottom of a connecting rod, an arc-shaped sleeve is provided on the outer side of the installation plate, a reinforcing block is fixedly connected to the top of the installation plate, the inner cavity of the reinforcing block has an overflow hole, and one side of the reinforcing block is fixedly connected to the outer side of the connecting rod.

[0011] As provided by this utility model, an unmanned surface vessel for surveying is preferably provided, including a spring located in the inner cavity of a connecting rod. Both ends of the spring are welded with locking blocks. The inner cavity of the locking blocks is slidably connected to a limiting rod. The bottom and top of the locking blocks are fixedly connected to limiting blocks. The outer side of the limiting blocks is slidably connected to the inner cavity of the connecting rod.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] This unmanned surface vessel (USV) for surveying features a locking block that engages with a locking hole on the outside of the connecting sleeve when the connecting rod is inserted into the connecting sleeve. This secures the connecting rod to the connecting sleeve, allowing for the installation of the detection unit. To disassemble the detection unit, simply press the locking block to disengage it from the locking hole, and the connecting rod can be pulled out of the connecting sleeve. By using two locking blocks, the connection stability between the connecting rod and the connecting sleeve is improved. Furthermore, the arc-shaped sleeve on the outside of the mounting plate allows water to flow smoothly over the mounting plate, reducing the resistance experienced by the mounting plate in the water and thus reducing the impact of water flow on the connecting rod. This solves the problems of poor locking stability and inconvenience in adjusting the height of the boom in current devices. Attached Figure Description

Detailed Implementation

[0021] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0022] Please refer to the following: Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 ,in Figure 1 A schematic diagram of a preferred embodiment of the unmanned survey vessel provided by this utility model; Figure 2 This is a schematic diagram of the adjustment mechanism of this utility model; Figure 3 This is a cross-sectional view of the connecting mechanism of this utility model; Figure 4 This is a schematic diagram of the connection structure between the docking block and the docking seat of this utility model; Figure 5 This is a top view of the mounting plate of this utility model; Figure 6This is a top view of the fixed sleeve of this utility model. A surveying unmanned surface vessel includes a hull 1, a moon pool compartment 2 inside the hull 1, an adjustment mechanism 3 inside the moon pool compartment 2, a connecting mechanism 4 at the bottom of the adjustment mechanism 3, an installation mechanism 5 at the bottom of the connecting mechanism 4, a detection unit 6 at the bottom of the installation mechanism 5, and a fixing mechanism 7 inside the cavity of the connecting mechanism 4.

[0023] In this embodiment: the hull 1 and the lunar pool compartment 2 are both selected from the hull and lunar pool compartment disclosed in public number CN218181093U. The detection unit 6 is generally set as a single-beam sonar depth sounder, side-scan sonar, ADCP, etc., and these surveying devices are fixed to the mounting mechanism 5 by bolts.

[0024] As a technical optimization of this utility model, it includes a fixed sleeve 301, which is fixed to the top of the inner cavity of the moon pool compartment 2. A fixed rod 302 is slidably connected to the inner cavity of the fixed sleeve 301. A fixed bolt 303 is provided in the inner cavity of the fixed rod 302. A fixed nut 304 is threadedly connected to the outer side of the fixed bolt 303.

[0025] The adjustment mechanism 3 also includes a fixed sleeve 301, a stabilizing block 305 is fixedly connected to the outside of the fixed sleeve 301, and a stabilizing rod 306 is slidably connected to the inner cavity of the stabilizing block 305.

[0026] In this embodiment: the bottom of the stabilizing rod 306 is fixedly connected to the outside of the fixing rod 302 via a connecting block. The inner cavity of the fixing rod 302 has multiple through holes. When adjusting the detection depth of the detection unit 6, the fixing nut 304 can be unscrewed from the outside of the fixing bolt 303, and then the fixing bolt 303 can be pulled out from the fixing rod 302. The fixing rod 302 can then be pulled. After the fixing rod 302 is pulled to the desired position, the fixing bolt 303 is returned to its original position and inserted into the corresponding through hole. Then the fixing nut 304 can be tightened. This makes it convenient for the user to adjust the detection depth of the detection unit 6.

[0027] As a technical optimization of this utility model, the connecting mechanism 4 includes a connecting rod 401, a connecting sleeve 402 is slidably connected to the outer side of the connecting rod 401, the top of the connecting sleeve 402 is fixedly connected to the bottom of the fixing rod 302, a docking block 404 is fixedly connected to the top of the connecting rod 401, a docking seat 403 is fixedly connected to the inner wall of the connecting sleeve 402, and the outer side of the docking block 404 is engaged with the inner cavity of the docking seat 403.

[0028] In this embodiment: after the connecting rod 401 is inserted into the connecting sleeve 402, the mating block 404 can be inserted into the mating seat 403. By setting the mating block 404 and the mating seat 403, the connection stability of the connecting rod 401 and the connecting sleeve 402 is improved.

[0029] As a technical optimization of this utility model, it includes a mounting plate 501, the bottom of the mounting plate 501 is fixedly connected to the bottom of the connecting rod 401, an arc-shaped sleeve 502 is provided on the outer side of the mounting plate 501, a reinforcing block 503 is fixedly connected to the top of the mounting plate 501, a flow hole 504 is opened in the inner cavity of the reinforcing block 503, and one side of the reinforcing block 503 is fixedly connected to the outer side of the connecting rod 401.

[0030] In this embodiment: the inner cavity of the mounting plate 501 has four fixing holes for fixing the detection unit 6 with bolts. There are four reinforcing blocks 503, which are arranged in a cross shape on the outside of the connecting rod 401, which improves the connection stability between the connecting rod 401 and the mounting plate 501. The reinforcing block 503 has a flow hole 504 inside, which can reduce the resistance of the reinforcing block 503 underwater. The arc-shaped sleeve 502 provided on the outside of the mounting plate 501 can make the water flow smoothly pass through the mounting plate 501, thereby reducing the resistance of the mounting plate 501 in the water and thus reducing the impact of the water flow on the mounting plate 501.

[0031] As a technical optimization of this utility model, it includes a spring 701, which is located in the inner cavity of the connecting rod 401. Both ends of the spring 701 are welded with a locking block 702. The inner cavity of the locking block 702 is slidably connected to a limiting rod 703. The bottom and top of the locking block 702 are fixedly connected to a limiting block 704. The outer side of the limiting block 704 is slidably connected to the inner cavity of the connecting rod 401.

[0032] In this embodiment: when the connecting rod 401 is inserted into the connecting sleeve 402, the locking block 702 can be locked into the locking hole on the outside of the connecting sleeve 402, thereby fixing the connecting rod 401 and the connecting sleeve 402 together, thus completing the installation of the detection unit 6. When disassembling the detection unit 6, simply press the locking block 702 to disengage it from the locking hole, and the connecting rod 401 can be pulled out from the connecting sleeve 402, thus completing the disassembly of the detection unit 6. By setting two locking blocks 702, the connection stability between the connecting rod 401 and the connecting sleeve 402 is improved. Furthermore, by setting an arc-shaped sleeve 502 on the outside of the mounting plate 501, the water flow can pass smoothly through the mounting plate 501, thereby reducing the resistance experienced by the mounting plate 501 in the water, and thus reducing the impact of the water flow on the connecting rod 401 when passing through the mounting plate 501.

[0033] The working principle of the unmanned surface vessel for surveying provided by this utility model is as follows:

[0034] When installing the detection unit 6, the connecting rod 401 can be inserted into the connecting sleeve 402. When the connecting rod 401 is inserted into the connecting sleeve 402, the locking block 702 can be locked into the locking hole on the outside of the connecting sleeve 402, thereby fixing the connecting rod 401 and the connecting sleeve 402 together, thus completing the installation of the detection unit 6. When disassembling the detection unit 6, simply press the locking block 702 to disengage it from the locking hole, and the connecting rod 401 can be pulled out from the connecting sleeve 402, thus completing the disassembly of the detection unit 6. By setting two locking blocks 702, the connection stability between the connecting rod 401 and the connecting sleeve 402 is improved. Furthermore, by setting an arc-shaped sleeve 502 on the outside of the mounting plate 501, the water flow can pass smoothly over the mounting plate 501, thereby reducing the resistance experienced by the mounting plate 501 in the water, and thus reducing the impact of the water flow on the connecting rod 401 when passing over the mounting plate 501.
