Description

Technical Field

[0001] This utility model relates to the field of water conservancy engineering technology, specifically to a fixing device for underwater surveying instruments. Background Technology

[0002] Underwater topographic mapping is an important technology in fields such as marine engineering, hydraulic engineering, resource exploration, and environmental protection. It aims to accurately obtain information such as the geomorphic features, depth, and slope of underwater terrain through a series of scientific methods and techniques, providing a reliable basis for decision-making in related fields.

[0003] In the prior art, the authorized announcement number CN222992630U describes a fixing device for underwater surveying instruments in water conservancy projects. This device includes a horizontal plate and auxiliary components. The auxiliary components include a boom, mounting plate, mounting frame, main body of the measuring equipment, protective cover, and locking components. During use, the main body of the measuring equipment mounted on the mounting frame can measure the density and pressure of the water in the surveying area. During the measurement process, the outer protective cover provides safety protection, preventing the main body of the measuring equipment from being impacted by external forces. This ensures the safety of the measuring instrument during the preliminary measurement work of underwater surveying, preventing it from being affected by aquatic organisms or debris, thus protecting the accuracy of the measurement and even causing damage, thereby facilitating safe measurement.

[0004] Existing underwater surveying instrument fixing devices typically use protective covers to protect the main body of the surveying instrument from damage caused by impacts from aquatic organisms or debris. However, these protective covers are mostly fixed with multiple bolts. When it is necessary to inspect or maintain the main body of the surveying instrument inside the protective cover, the disassembly process is cumbersome and time-consuming, reducing the practicality of the device.

[0007] Preferably, the connection structure includes a hanger rod, which is fixedly connected to the top of the mounting plate, and a horizontal plate is fixedly connected to the top of the hanger rod.

[0008] Preferably, the cable protection structure includes a slot, which is located on the top of the mounting plate. Two slots are formed inside the slot, and each slot has a small arc-shaped groove at its bottom. A protective tube is provided inside the slot, and two locking blocks are fixedly connected to the outside of the protective tube. The two locking blocks are respectively positioned inside the two small arc-shaped grooves, and each locking block has a fixing slot at its bottom. The protective tube provides safe protection for the working cable.

[0009] Preferably, the cable protection structure further includes a vertical slot, which is located at the top of the mounting plate. A pressing block is slidably disposed inside the vertical slot, and an L-shaped block is fixedly connected to the bottom of the pressing block. A second spring is sleeved on the outside of the L-shaped block, and both ends of the second spring are fixedly connected to the pressing block and the mounting plate, respectively. The L-shaped block passes through the bottom of the vertical slot and is slidably connected to the mounting plate. An annular block is fixedly connected to one end of the L-shaped block, and two fixing rods are fixedly connected to the top of the annular block. Both fixing rods pass through the bottom of the mounting plate and extend into the two small arc-shaped grooves. The two fixing rods are respectively disposed inside the two fixing slots. The second spring serves to provide elastic compression and elastic reset.

[0010] Preferably, the lever structure includes an internal gear ring and a large arc groove.

[0011] Preferably, the elastic element includes a spring, which is disposed inside the convex groove and sleeved on the outside of the wire rope. The two ends of the spring are fixedly connected to the convex rod and the mounting plate, respectively. The spring serves to provide elastic compression and elastic reset.

[0012] Preferably, the mounting plate has multiple positioning grooves at its bottom, the positioning grooves are connected to the convex grooves, and the cylindrical frame is disposed inside the positioning grooves.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. This application uses multiple steel wire ropes to pull multiple convex rods towards the installation groove. The multiple convex rods slide inside the multiple convex grooves, while multiple springs elastically compress them. When the multiple convex rods are pulled out from inside the multiple cylindrical frames, the limit on the cylindrical frames can be released, thereby realizing the disassembly of the protective cover. This structural design facilitates disassembly by personnel, so that personnel can inspect or maintain the underwater surveying instruments and equipment inside the protective cover.

[0015] 2. This application uses a pressing block to drive an L-shaped block to slide downwards on the mounting plate, while the two springs elastically compress. As the L-shaped block slides, it drives two fixed rods downwards via a ring block. The two fixed rods then move out of the two fixed slots, thereby releasing the restriction on the two locking blocks. Afterwards, the protective tube is rotated to rotate the two locking blocks from the two small arc-shaped grooves into the two locking slots. The protective tube is then lifted upwards to complete the disassembly of the protective tube. Therefore, protective tubes of different lengths can be replaced according to the water immersion depth of the device to meet the needs of different usage scenarios. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Example: Figure 1 - Figure 5 As shown, this utility model provides a technical solution for a fixing device for an underwater surveying instrument, including a mounting plate 1. The top of the mounting plate 1 is provided with a connecting structure and a cable protection structure. The connecting structure includes a boom 2, which is fixedly connected to the top of the mounting plate 1. A horizontal plate 3 is fixedly connected to the top of the boom 2. A mounting groove 6 is formed on the inner side of the mounting plate 1. Multiple circular holes 600 are formed on the inner side of the mounting groove 6. A convex groove 601 is formed on one side of each circular hole 600. Multiple rotating shafts 11 are rotatably connected inside the mounting groove 6. A lever structure is provided between the multiple rotating shafts 11. A steel wire rope 12 is fixedly connected to the outer side of each rotating shaft 11. One end of the steel wire rope 12 passes through the circular hole 600 and is fixedly connected to the convex rod. 14. A convex rod 14 is slidably disposed inside a convex groove 601. An elastic element is provided on one side of the convex rod 14. The elastic element includes a spring 13. The spring 13 is disposed inside the convex groove 601 and is sleeved on the outside of the wire rope 12. The two ends of the spring 13 are fixedly connected to the convex rod 14 and the mounting plate 1, respectively. A cylindrical frame 400 is slidably disposed on the outside of one end of the convex rod 14. Multiple positioning grooves 100 are opened at the bottom of the mounting plate 1. The positioning grooves 100 communicate with the convex groove 601. The cylindrical frame 400 is disposed inside the positioning grooves 100. A protective cover 4 is fixedly connected between the multiple cylindrical frames 400. Underwater surveying instruments and equipment 5 are installed inside the protective cover 4.

[0024] The lever structure includes an internal gear ring 7 and a large arc groove 9. The internal gear ring 7 is located inside the mounting groove 6 and is rotatably connected to the mounting plate 1. Multiple gears 8 are meshed on the inner side of the internal gear ring 7. The multiple gears 8 are respectively fixedly connected to the outer side of multiple rotating shafts 11. The large arc groove 9 is opened at the top of the mounting plate 1. A lever block 10 is slidably arranged inside the large arc groove 9. The lever block 10 is fixedly connected to the top of the internal gear ring 7.

[0025] Specifically, pushing the lever 10 causes the internal gear ring 7 to rotate inside the mounting groove 6. The internal gear ring 7 meshes with multiple gears 8, which in turn drive multiple rotating shafts 11 to rotate. The multiple rotating shafts 11 then wind up multiple wire ropes 12. As the wire ropes 12 wind up, they pull multiple convex rods 14 towards the mounting groove 6. The convex rods 14 slide inside the multiple convex grooves 601, while the multiple springs 13 are elastically compressed. When the convex rods 14 are pulled out from inside the multiple cylindrical frames 400, the limit on the cylindrical frames 400 can be released, thus enabling the disassembly of the protective cover 4. This structural design facilitates disassembly by personnel, allowing them to inspect or maintain the underwater surveying instruments and equipment 5 inside the protective cover 4.

[0026] Example: Figure 1 , Figure 2 and Figure 5 As shown, the cable protection structure includes a slot 15, which is located on the top of the mounting plate 1. Two slots 150 are formed inside the slot 15, and each slot 150 has a small arc-shaped groove 151 at its bottom. A protective tube 16 is located inside the slot 15, and two locking blocks 17 are fixedly connected to the outside of the protective tube 16. The two locking blocks 17 are respectively located inside the two small arc-shaped grooves 151, and each locking block 17 has a fixing slot at its bottom. The cable protection structure also includes a vertical slot 18, which is located on the top of the mounting plate 1. A sliding device is installed inside the vertical slot 18. A pressing block 19 is provided, and an L-shaped block 20 is fixedly connected to the bottom of the pressing block 19. A second spring 21 is sleeved on the outside of the L-shaped block 20. The two ends of the second spring 21 are fixedly connected to the pressing block 19 and the mounting plate 1, respectively. The L-shaped block 20 passes through the bottom of the vertical slot 18 and is slidably connected to the mounting plate 1. An annular block 22 is fixedly connected to one end of the L-shaped block 20. Two fixing rods 23 are fixedly connected to the top of the annular block 22. Both fixing rods 23 pass through the bottom of the mounting plate 1 and extend into the two small arc-shaped grooves 151. The two fixing rods 23 are respectively set inside the two fixing slots.

[0027] Specifically, pressing the pressing block 19 causes the L-shaped block 20 to slide downwards on the mounting plate 1, while the spring 21 is elastically compressed. As the L-shaped block 20 slides, it drives the two fixing rods 23 downwards via the annular block 22. The two fixing rods 23 move out of the two fixing slots respectively, thereby releasing the restriction on the two locking blocks 17. Then, rotating the protective tube 16 rotates the two locking blocks 17 from the two small arc-shaped grooves 151 into the two locking slots 150. The protective tube 16 is then lifted upwards to complete the disassembly of the protective tube 16. Therefore, protective tubes 16 of different lengths can be replaced according to the water immersion depth of the device to meet the needs of different usage scenarios.
