Description

Technical Field

[0001] This invention belongs to the technical field of marine monitoring equipment, and particularly relates to an internal cylindrical multifunctional hydrological support. Background Technology

[0002] Hydrological monitoring is a complex and comprehensive system engineering project that uses scientific methods to monitor, measure, analyze, and provide early warnings about the spatiotemporal distribution and changing patterns of water in nature. It is an interdisciplinary subject. Hydrological monitoring consists of four parts: a monitoring center, a communication network, front-end monitoring equipment, and measuring equipment. Currently used detection devices are complex in structure and expensive, requiring fixed installation on the seabed, which is difficult to install and requires high waterproof performance. Furthermore, existing hydrological detection devices are mostly installed overboard, often using manual handheld suspension rod measurements or cable tests. Improper manual operation or swaying in the water during placement can lead to inaccurate data. The lack of protective measures such as limiting blocks during placement makes the suspension rod prone to impact with rocks or the seabed during manual lowering, causing damage and affecting its service life. Summary of the Invention

[0003] The purpose of this invention is to provide an in-ship cylindrical multifunctional hydrological support to solve the problems mentioned in the background art. This invention solves the problems of transferring work from external to internal operations, transforming conventional manual lifting into automated mechanical lifting, and using a modular connection to achieve instrument replacement. The ship hull support design features watertight partitions and tubing, and guide grooves, guide bosses, and adjustable limiters reduce device swaying and vibration. The device has a simple, beautiful, and elegant cylindrical appearance, and its operation is more convenient and safer.

[0004] To achieve the above objectives, the present invention is implemented through the following technical solution:

The sliding cylinder assembly includes a sliding cylinder body and a waterproof structure installed inside the sliding cylinder body. The top of the waterproof structure is connected to the lifting device via a hook, and the end is connected to a connecting section via a flange. At the end of the connecting section is a base for placing the testing equipment. Two vertical guide grooves are provided on both sides of the sliding cylinder body. The sleeve assembly includes a sleeve body, and a guide boss that mates with the guide grooves is welded to the upper part inside the sleeve body. Under the action of the lifting device, the sliding cylinder body slides downward or upward along the predetermined trajectory of the guide boss and the guide grooves within the sleeve body to realize the lowering and raising of the testing equipment.

[0006] Preferably, adjustment limiters are inserted above the two sides of the sleeve body, and the adjustment limiters and the guide boss are in the same vertical plane. When the slide body moves the equipment base to the detection position, the position of the slide body is fixed by tightening the adjustment limiters into the guide groove.

[0007] Preferably, the waterproof structure includes a pipe column, a sleeve fitted over the pipe column, a detection port cover plate welded above the pipe column and sleeve for sealing the top opening of the slide body, and a surge stop plate welded below the pipe column and sleeve for sealing the bottom opening of the slide body. The bottom ends of the pipe column and sleeve are connected to a connecting section via a flange, the connecting section is connected to an equipment base, and a detection device is placed on the equipment base.

[0013] Preferably, the sleeve assembly is embedded and fixed on the cabin floor; a cylindrical through-hole is pre-set on the cabin floor, and the sleeve body can be inserted into the cylindrical through-hole and fixed with resin sealant.

[0014] Preferably, a ring of evenly distributed flange studs is welded to the outer periphery of the top of the sleeve body, and a ring of stud holes that mate with the flange studs are provided on the outer periphery of the detection port cover plate. When the slide body slides down into the detection position within the sleeve body, the flange studs mate with the stud holes.

[0015] Working principle: The main body of the slide cylinder is equipped with a pipe column, sleeve, pipe section and sleeve bottom flange interface, elbow plate, waterproof partition, guide slide groove, lifting ring, and lifting ring; the traction steel rope is wound around the hoisting motor, and the traction steel rope passes through the fixed frame and connects to the pulley and hook; the connecting section is a modular configuration, and different module lengths can be selected according to the required length.

Detailed Implementation

[0032] To enable those skilled in the art to better understand the technical solutions of this invention, the technical solutions in the embodiments of this invention will be clearly and completely described below. Obviously, the described embodiments are only some embodiments of this invention, and not all embodiments. Based on the embodiments of this invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of this invention.

[0033] To address the shortcomings of existing technologies: Currently used detection devices are complex and expensive, requiring fixed installation on the seabed, making installation difficult and demanding high waterproofing performance. Furthermore, existing hydrological detection devices are mostly mounted overboard, relying on manual handheld rod measurements or cable tests. Improper manual operation or swaying in the water during placement can lead to inaccurate data. The lack of protective measures against limiting blocks during placement makes the rod susceptible to damage from impacts with rocks or the seabed, affecting its lifespan. Therefore, this invention proposes an in-ship cylindrical multi-functional hydrological support to solve the aforementioned technical problems.

[0034] The present invention will be further described in detail below through embodiments.

[0035] Example 1: Refer to Appendix Figure 1-4 A shipboard cylindrical multifunctional hydrological support includes a sleeve assembly, a lifting device, and a sliding cylinder assembly located above the sleeve assembly and controlled by the lifting device for raising and lowering. The sliding cylinder assembly includes a sliding cylinder body 6 and a waterproof structure installed inside the sliding cylinder body 6. The top of the waterproof structure is connected to the lifting device via a hook 7, and the end is connected to a connecting segment 16 via a flange 26. An equipment base 17 for placing detection equipment is connected to the end of the connecting segment 16. Two vertical guide grooves 21 are provided on both sides of the sliding cylinder body 6. The sleeve assembly includes a sleeve body 18. A guide boss 20 that cooperates with the guide grooves 21 is welded to the upper part of the sleeve body 18. Under the action of the lifting device, the sliding cylinder body 6 slides downward or upward along the predetermined trajectory of the guide boss 20 and the guide grooves 21 within the sleeve body 18 to realize the lowering and raising of the detection equipment.

[0036] In this embodiment, adjustment limiters 22 are inserted above the two sides of the sleeve body 18, and the adjustment limiters 22 and the guide boss 20 are in the same vertical plane. When the slide body 6 moves the equipment base 17 to the detection position, the position of the slide body 6 is fixed by tightening the adjustment limiters 22 into the guide groove 21.

[0037] In this embodiment, the waterproof structure includes a pipe column 8 and a sleeve 12 fitted over the pipe column 8. A detection port cover 24 for sealing the top opening of the slide body 6 is welded above the pipe column 8 and the sleeve 12, and a surge stop plate 25 for sealing the bottom opening of the slide body 6 is welded below. The bottom ends of the pipe column 8 and the sleeve 12 are connected to the connecting section 16 through a flange 26. The connecting section 16 is connected to the equipment base 17, and the detection equipment is placed on the equipment base 17.

[0038] In this embodiment, an elbow plate 13 is installed between the sleeve 12 and the detection port cover 24, and between the sleeve 12 and the anti-surge plate 25. Two vertically aligned and symmetrical waterproof partitions 19 are provided between the detection port cover 24 and the anti-surge plate 25, located outside the upper and lower elbow plates 13. A connecting rod sleeve is provided outside the two waterproof partitions 19. Nuts 23 are symmetrically arranged on both sides of the bottom of the sleeve body 18. When the sliding cylinder body 6 slides downwards within the sleeve body 18 to the detection position, it is threadedly connected to the nuts 23 at the bottom of the sleeve body 18 via two through connecting rods 10 that sequentially pass through the detection port cover 24, the connecting rod sleeve, and the anti-surge plate 25. Multiple lifting rings 11 are installed above the detection port cover 24, and the lifting rings 11 are actively engaged with the hooks 7.

[0039] Example 2 differs from Example 1 in that it further includes a ring of evenly distributed flange studs 19 welded to the outer periphery of the top of the sleeve body 18, and a ring of stud holes that mate with the flange studs 19 on the outer periphery of the detection port cover. When the slide body 6 slides downward to the detection position within the sleeve body 18, the flange studs 19 mate with the stud holes.

[0040] Example 3 differs from Example 1 in that, in this example, the lifting device is further included, with the lifting device mounted on the side wall 2 and the ceiling 3 of the cabin. The lifting device includes a first fixed frame 4 mounted above one side of the side wall 2 and a first pulley 5 mounted on the first fixed frame 4; a second fixed frame 4-1 mounted below the ceiling 3 and a second pulley 5-1 mounted on the second fixed seat 4-1; a lifting motor 15 is mounted below one side of the side wall 2; a traction steel cable 14 is wound around the lifting motor 15; the end of the traction steel cable 14 passes sequentially through the first pulley 5 and the second pulley 5-1 and connects to a hook 7; the hook 7 is connected to the top of the waterproof structure.

[0041] Example 4 differs from Example 1 in that, in this example, the sleeve assembly is embedded and fixed on the cabin floor 1; a cylindrical through-hole is pre-set on the cabin floor 1, and the sleeve body 18 is inserted into the cylindrical through-hole and fixed with resin sealant.

[0042] Implementation principles of Examples 1 to 4: The main body of the slide cylinder includes a pipe column, a sleeve, a pipe section and a flange interface at the bottom of the sleeve, an elbow plate, a waterproof partition, a guide chute, and a lifting ring. A traction steel rope is wound around a lifting motor, and the traction steel rope passes through a fixed frame and connects to a pulley and hook. The connecting sections are modular, allowing for selection of different module lengths according to required lengths. The flanges are fixed at both ends with studs, and the lower end connects to the equipment base. The lifting motor provides traction to pull the slide cylinder downwards, adjusting the limit switch, guide boss, and guide. The chute slides in a directional manner. When it reaches the detection position, the through-link rod is locked to the nut at the bottom of the sleeve body. The through-link rod and nut are threaded in all directions for secure fixation. Monitoring equipment is installed on the equipment base to achieve underwater hydrological monitoring. Loosen the threaded flange connections at both ends of the sleeve body and the chute body, loosen the through-link rod, and the hoisting motor provides traction force through the traction steel rope, fixing frame, and pulleys to pull the chute upwards along the prescribed trajectory of the adjusting limit device, guide boss, and guide chute. This causes the chute body to move the connecting section and equipment base out of the sleeve body. Remove the flange bolt connections between the two sections of the connecting section, remove the hydrological equipment, and store it properly.

[0043] Lifting motor: also called "lifting mechanism", the lifting motor drives the drum to rotate through the coupling and the hollow shaft of the reducer, thereby causing the wire rope wound on the drum to drive the device to rise or fall.

[0044] Equipment base: Provides support and serves as a platform for equipment installation. It reduces vibration, minimizes machine imbalance, increases resistance, ensures secure installation, lowers the center of gravity, and enhances stability.

[0045] Pipe column: Made of 316 stainless steel, used for layered waterproofing and insect and rodent protection, while also reinforcing the strength of the slide joint.

[0046] Through-link connecting rod: made of 316 stainless steel, the bottom of the slide cylinder body and the slide sleeve body are connected, and the connecting rod cover is fastened with studs to ensure a tight fit between the mating surfaces.

[0047] Pulley: A pulley made of metal, whose main functions are to pull loads, change the direction of force, and transmit power.

[0048] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. It will be apparent to those skilled in the art that the invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics.

Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within the scope of the invention.

This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
