Description

Technical Field

[0001] The present invention belongs to the field of underwater survey equipment, and in particular relates to a portable device for retrieving and deploying underwater survey instruments. Background Art

[0002] Currently, during marine surveying and mapping, various marine survey installation devices are mostly used to assist underwater survey instruments in detecting the seabed terrain and pipelines. Since the marine survey installation devices are large and heavy, it is difficult to place the equipment at the target position by manpower, and ordinary small workboats cannot meet their operation requirements. Therefore, it is necessary to borrow the ship's lifting equipment of a large workboat for operation. There are two problems in the operation process of a large workboat: on the one hand, the lifting equipment of a large workboat needs to serve multiple tasks, with few equipment and heavy tasks, and cross-operation cannot be achieved, which greatly prolongs the construction period; on the other hand, during the operation process, it is strictly prohibited for staff to walk and work under the lifting device of a large ship, otherwise it is extremely easy to cause safety accidents, and during the application of the lifting device, the hull will inevitably shake, causing the instrument to collide with the hull and resulting in instrument damage. In addition, in the traditional operation process, the application and placement of underwater survey instruments are usually completed by adjusting the underwater instrument installation pipe into the ship's side and moving it outside the ship's side, which requires a large amount of manpower, and since most of the instrument installation pipes are more than ten meters long, during the process of turning in and out, the instrument installation pipe is extremely easy to cross and collide with the ship's side, causing the ship to shake violently and bringing unnecessary damage to the instrument. Since there is a lack of an instrument installation and retrieval device that takes into account shortening the construction period, ensuring the safety of construction personnel and equipment, saving manpower and being applicable to various ship types in traditional operations, we have made an innovation in this regard and proposed a portable device for retrieving and deploying underwater survey instruments. Summary of the Invention

[0003] To solve the above problems, the present invention provides a portable device for retrieving and deploying underwater survey instruments. This device uses a hydraulic assembly to adjust the boom, ensuring the stability and flexibility of the retrieval and deployment device; uses an instrument recovery seat and an instrument fixing groove to facilitate the user to retrieve and deploy underwater survey instruments; uses a manual winch assembly to ensure the safety of retrieving and lowering underwater survey instruments, effectively avoiding high-grade insulation problems, reducing the number of personnel for lowering and retrieving instruments, and reducing the use cost.

[0004] To solve the above technical problems, the technical solution adopted by the present invention is: a portable device for retrieving and deploying underwater survey instruments, including a carrier seat detachably and fixedly arranged on the ship's side and a retrieval and deployment device detachably assembled on the carrier seat for retrieving and deploying underwater survey instruments.

[0005] Further, a lower support portion is vertically provided on the carrier base. The retracting and deploying device includes an upper carrier plate, a boom that is driven to pitch, and an upper support portion that is vertically disposed relative to the bottom surface of the upper carrier plate. The upper support portion and the lower support portion are correspondingly and cooperatively connected to achieve rotatable connection between the upper carrier plate and the carrier base; the tail end of the boom is movably connected to the upper carrier plate through a pin.

[0006] In this technical solution, the carrier base is used to fixedly install the retracting and deploying device and fix it to the ship's side, thereby fixing the entire device to the ship's side; when the retracting and deploying device is in use, the upper support portion and the lower support portion are assembled so that the carrier base and the retracting and deploying device form a rotatable connection, facilitating the adjustment of the angle of its lowering.

[0007] Further, the retracting and deploying device further includes a hydraulic assembly for driving the boom, a winch assembly, and a fixed pulley. The top end of the hydraulic assembly is movably connected to the boom, and the bottom end is movably connected to the upper carrier plate; the fixed pulley is fixedly provided at the head end of the boom, the winch assembly is fixedly connected to the upper carrier plate, and the stainless steel wire rope inside the winch assembly bypasses the fixed pulley and is fixedly connected to a shackle.

[0008] In this technical solution, the hydraulic assembly can lift the boom, and together with the winch assembly to control the length of the stainless steel wire rope, it can realize the lifting and lowering of the underwater measuring instrument; the fixed pulley facilitates the retracting and deploying of the stainless steel wire rope.

[0009] Further, the connection mechanism of the carrier base includes a fixed top plate, an outer plate and an inner plate that can be clamped on both the inner and outer sides of the ship's side. A clamping plate for clamping the ship's side and the carrier base is provided on the inner plate. The clamping plate is threadedly fixed to the inner plate through a locking lead screw, and the clamping plate is disposed between the inner plate and the outer plate. A lead screw rocker is fixedly provided at the end of the locking lead screw.

[0010] In this technical solution, the carrier base is fixedly installed on the ship's side, where the ship's side is installed between the outer plate and the clamping plate, and the position of the clamping plate is adjusted by rotating the lead screw rocker to fix the ship's side and the carrier base.

[0011] Further, an instrument recovery seat is movably connected to the bottom of the fixed top plate of the carrier base, and the instrument recovery seat is locked and fixed to the fixed top plate through a setscrew.

[0012] Further, an instrument fixing groove is fixedly provided at the head end of the instrument recovery seat, and the instrument fixing groove is a semi-circular groove.

[0013] In this technical solution, the instrument recovery seat and the instrument fixing groove are provided for placing and installing the pipe. The instrument fixing groove is set as semi-circular, which can effectively prevent the instrument installation pipe from falling off.

[0014] Furthermore, the length of the tail end of the upload plate is longer than that of the instrument recovery seat.

[0015] Furthermore, the hydraulic main unit is a manual hydraulic main unit, and its lower end is provided with a hydraulic lever for adjusting the height of the hydraulic main unit; the winch main unit is a manual winch main unit.

[0016] In this technical solution, using a manual hydraulic main unit not only effectively avoids the insulation problem that is difficult to solve when using electricity in a humid environment, but also reduces the volume and weight of the retraction and deployment system to a certain extent, making the device more lightweight and flexible; using a manual winch main unit effectively avoids the problem of difficult electrical insulation in a humid environment, providing safety protection for construction workers who frequently use the retraction and deployment system.

[0017] Furthermore, the shackle is detachably connected to the clamp, the clamp is fixedly clamped on the outer wall of the installation pipe, and an underwater measuring instrument is fixedly installed at the head end of the installation pipe.

[0018] In this technical solution, the clamp is used to fix the installation pipe, and the shackle is detachably installed with the clamp, which is used to fixedly connect the installation pipe to achieve the purpose of transferring the underwater measuring instrument, and at the same time prevent the installation pipe from falling off and causing damage to the underwater measuring instrument.

[0019] A method for using a portable device for retracting and deploying an underwater measuring instrument includes the following steps:

[0020] 1) Fix the carrier seat to the ship's side.

[0021] 2) Fix the tail end of the installation pipe to the ship's side mounting bracket, and place the position adjacent to the head end in the instrument fixing groove on the instrument fixing seat, so that the ship's side mounting bracket and the instrument recovery seat support the installation pipe to keep it stable; among them, an underwater measuring instrument is fixedly installed at the head end of the installation pipe.

[0022] 3) Actively connect the retraction and deployment device to the carrier seat, and then fix the shackle to the clamp, so that the retraction and deployment device is fixed to the installation pipe.

[0023] 4) Lower and retract the underwater measuring instrument by operating the hydraulic main unit and the winch main unit in the retraction and deployment device.

[0024] The advantages and positive effects of the present invention are:

[0025] 1. By providing a boom, an upload plate and a hydraulic main unit, the longitudinal telescopic operation of the boom is realized, which is convenient for the user to quickly complete the retraction and deployment of the underwater measuring instrument while ensuring the safety of the underwater measuring instrument.

[0026] 2. The carrier base is provided with an instrument recovery seat and an instrument fixing groove for storing the installation pipe when recovering the installation pipe. At the same time, it is used in conjunction with the retracting and deploying device, enabling the staff to quickly install the underwater measuring instrument in a rocking ship, reducing the frequency of overall disassembly and assembly of the installation pipe by the users, improving the stability of the retraction and deployment of the installation pipe, providing higher safety protection for the underwater measuring instrument, and enabling the staff to operate as normal in bad weather.

[0027] 3. The adjustment instrument recovery seat is fixed to the carrier base by a setscrew. The relative position between the instrument recovery seat and the carrier base can be adjusted by adjusting the tightness of the setscrew, thereby facilitating the retraction and deployment of the installation pipe and preventing the installation pipe from colliding with the instrument recovery seat and the ship's side.

[0028] 4. By providing a carrier base and a retracting and deploying device, it can be installed at different positions and operate on different working ships, improving the convenience of using the underwater measuring instrument. BRIEF DESCRIPTION OF THE DRAWINGS

Specific embodiments

[0039] The following will describe in detail the specific embodiments of the present invention with reference to the accompanying drawings.

[0040] As Figure 1-9 shown: A portable device for retracting and deploying an underwater measuring instrument, comprising a mounting base 2 detachably and fixedly arranged on the ship's side 1 and a retracting and deploying device 3 detachably assembled on the mounting base 2 for retracting and deploying the underwater measuring instrument 9. Among them, the detachable connection can be a threaded nut connection, a plug-in connection or other connection methods. The mounting base 2 is used to fix the device to the ship's side 1 of the ship and at the same time to mount the retracting and deploying device 3, so as to facilitate the retracting and deploying of the underwater measuring instrument 9.

[0041] As Figure 2 and Figure 4 shown: A lower support part 11 is vertically arranged on the mounting base 2. The retracting and deploying device 3 comprises an upper loading plate 31, a lifting arm 32 driven to pitch, and an upper support part 33 vertically arranged relative to the bottom surface of the upper loading plate 31. The upper support part 33 and the lower support part 11 are correspondingly and cooperatively connected to realize the rotatable connection between the upper loading plate 31 and the mounting base 2. In this embodiment, the upper support part 33 can be a sleeve fixedly connected to the bottom of the upper loading plate 31, and the lower support part 11 can be a rotating shaft fixedly connected to the mounting base 2. The sleeve is sleeved on the rotating shaft so that the upper loading plate 31 can be rotatably connected to the mounting base 2 along the rotating shaft. The tail end of the lifting arm 32 is movably connected to the upper loading plate 31 through a pin 34. The retracting and deploying device 3 further comprises a hydraulic assembly 35, a winch assembly 36 and a fixed pulley 37 for driving the lifting arm 32. The top end of the hydraulic assembly 35 is movably connected to the lifting arm 32, and the bottom end is movably connected to the upper loading plate 31. The fixed pulley 37 is fixedly arranged at the head end of the lifting arm 32. The winch assembly 36 is fixedly connected to the upper loading plate 31, and the stainless steel wire rope 38 inside the winch assembly 36 bypasses the fixed pulley 37 and is fixedly connected to a shackle 6. Among them, the hydraulic assembly 35 is movably connected to the upper loading plate 31 and rotatably connected to the lifting arm 32. This design facilitates the user to flexibly adjust the height of the lifting arm 32 according to the use requirements.

[0042] AsFigure 4 As shown in the figure: The connecting mechanism of the carrier base 2 includes a fixed top plate 21, an outer plate 22 and an inner plate 23 that can be clamped on the inner and outer sides of the ship's side 1. A clamping plate 24 for clamping the ship's side 1 and the carrier base 2 is arranged on the inner plate 23. Among them, the clamping plate 24 is threadedly fixed to the inner plate 23 through a locking screw rod 25, and the clamping plate 24 is arranged between the inner plate 23 and the outer plate 22. A screw rod rocker 26 is fixedly arranged at the end of the locking screw rod 25. Among them, the ship's side 1 is installed between the outer plate 22 and the clamping plate 24. By shaking the screw rod rocker 26, the position of the clamping plate 24 can be adjusted, which is convenient for fixing the ship's side 1 between the clamping plate 24 and the outer plate 22, facilitating the installation and disassembly of the carrier base 2 and the ship's side 1. At the same time, this design enables the carrier base 2 to adapt to ship's sides 1 of different thicknesses, increasing its applicable range. Here, one or more groups of the clamping plate 24, the matching locking screw rod 25 and the screw rod rocker 26 can be arranged in parallel to effectively fix the ship's side 1.

[0043] As Figure 5 As shown in the figure: An instrument recovery base 4 is movably connected to the bottom of the fixed top plate 21 of the carrier base 2, and the instrument recovery base 4 is locked and fixed to the fixed top plate 21 through a setscrew 5. Among them, loosen the setscrew 5, move the instrument recovery base 4. When it moves to a suitable position, then tighten the setscrew 5 to adjust the position of the instrument recovery base 4 relative to the carrier base 2; setting the instrument recovery base 4 can avoid problems such as displacement and falling off of the installation pipe, indirectly ensuring the safety of the instrument.

[0044] In this embodiment, an instrument fixing groove 41 is fixedly arranged at the head end of the instrument recovery base 4. The instrument fixing groove 41 is a semi-circular groove, and the instrument fixing groove 41 is used to place and fix the installation pipe 8 equipped with the underwater measuring instrument 9 to prevent the installation pipe 8 from falling off and causing damage to the underwater measuring instrument 9.

[0045] Furthermore, the tail end of the upper loading plate 31 is longer than the instrument recovery base 4. This design facilitates the user to adjust the angle of the retracting and deploying device 3 according to the required angle.

[0046] Furthermore, the hydraulic main unit 35 is a manual hydraulic main unit, and a hydraulic lever 39 for adjusting the height of the hydraulic main unit 35 is provided at its lower end; the winch main unit 36 is a manual winch main unit. Using a manual boom hydraulic main unit can not only effectively avoid the insulation problem that is difficult to solve when using electricity in a humid environment, but also reduce the volume and weight of the retracting and deploying system to a certain extent, making the device more lightweight and flexible; using a manual winch main unit effectively avoids the problem of difficult electrical insulation in a humid environment, providing safety protection for construction workers who frequently use the retracting and deploying system.

[0047] Furthermore, the shackle 6 is detachably connected to the clamp 7, and the clamp 7 is fixedly mounted on the outer wall of the mounting tube 8, and the head end of the mounting tube 8 is fixedly mounted with an underwater measuring instrument 9. The mounting tube 8 is used to fix the underwater measuring instrument 9, and the shackle 6 fixes the mounting tube 8 by fixing the clamp 7 to transfer the underwater measuring instrument 9; the shackle 6 is detachably connected to the clamp 7, which is convenient for installation and removal at any time, and it can be disassembled and stored separately when not in use, which is convenient for transportation.

[0048] A method for using a portable device for retracting and deploying an underwater measuring instrument comprises the following steps:

[0049] 1) Fix the carrier 2 to the ship's side 1;

[0050] 2) The tail end of the mounting tube 8 is fixedly mounted on the shipboard mounting frame 10, and the position adjacent to the head end is placed in the instrument fixing groove 41 on the instrument fixing seat 4, so that the shipboard mounting frame 10 and the instrument recovery seat 4 support the mounting tube 8 to maintain stability; wherein the head end of the mounting tube 8 is fixedly mounted with an underwater measuring instrument 9;

[0051] 3) The retractable device 3 is movably connected to the carrier 2, and then the shackle 6 is fixed to the clamp 7, so that the retractable device 3 is fixed to the mounting tube 8;

[0052] 4) The underwater measuring instrument 9 is lowered and retracted by operating the hydraulic assembly 35 and the winch assembly 37 in the retracting and releasing device 3.

[0053] When the present invention is used, refer to Figure 1 , Figure 6 , Figure 7 and Figure 8 :

[0054] First, the user selects a lowering point and fixes the carrier 2 on the ship's side 1 at the corresponding position;

[0055] Secondly, the underwater measuring instrument 9 is installed at the head end of the installation pipe 8, and then the tail end of the installation pipe 8 is fixedly installed on the ship's side mounting frame 10 using the lifting device of the ship, and the position adjacent to the head end is placed in the instrument fixing groove 41; therefore, the installation pipe 8 and the underwater measuring instrument 9 are supported and maintained stable by the ship's side mounting frame 10 and the instrument fixing groove 41;

[0056] Next, the upper support part 33 is matched with the lower support part 11 so that the retractable device 3 is rotatably connected to the carrier 2; and the shackle 6 is fixed to the clamp 7, so that the retractable device 3 is fixed to the mounting tube; thereafter, the hydraulic assembly 35 is extended by pressing the hydraulic lever 39, thereby raising the boom 32 to an appropriate position, such as the highest position where the boom 32 and the upper loading plate 31 are close to vertical, and the shackle 6 is fixedly connected to the clamp 7, so that the retractable device 3 is fixedly connected to the mounting tube 8;

[0057] Next, open the valve of the hydraulic main unit 35. After the boom 32 is lowered to the corresponding position, manually rotate the winch main unit 36 to lower the underwater measuring instrument 9 to the target position for seabed detection work.

[0058] During the operation, due to the influence of construction requirements, the installation pipe 8 needs to be repeatedly retracted and extended. This requires the operator to frequently move the installation pipe 8 in and out of the ship's side. For convenient operation, during the instrument recovery process, the operator can tighten the stainless steel wire rope 38 by shaking the winch main unit 36, press the hydraulic lever 39 to raise the boom 32, so that the installation pipe 8 is raised to a certain position, then loosen the jackscrew 5, and adjust the position of the instrument recovery seat 4 according to the position of the installation pipe 8, so that the installation pipe 8 can be safely placed in the instrument fixing groove 41 of the instrument recovery seat 4. At this time, the stainless steel wire rope 38 continuously tightens the installation pipe 8. Then loosen the jackscrew 5, move the instrument recovery seat 4 relative to the carrier 2, and when adjusted to the optimal position, tighten the jackscrew 5 to fix the instrument recovery seat 4 on the carrier 2. Then adjust the installation pipe 8 to move into the instrument fixing groove 41. At this time, the instrument recovery seat 4 provides a supporting force for the installation pipe 8 to prevent it from slipping, and at the same time, the stainless steel wire rope 38 continuously suspends and pulls the installation pipe 8 to ensure its stability, providing secondary protection to effectively prevent the installation pipe 8 from falling; during the lowering process of the underwater measuring instrument 9, the operator can combine tightening the stainless steel wire rope 38 and lowering the boom 32 to gradually separate the installation pipe 8 from the instrument recovery seat 4 and complete the lowering of the underwater measuring instrument 9.

[0059] Compared with the prior art in which the boom of the hoisting device is long and the steel cable is also long, and it sways on the ship, making it inconvenient to retract the installation pipe 8 to the target position, the device of the present invention can simply and conveniently retract the installation pipe into the instrument recovery groove 41; at the same time, the retracting and extending device 3 of the present invention has good flexibility and applicability and can be applied to different ships for operation.

[0060] The above has described an embodiment of the present invention in detail, but the content described is only the preferred embodiment of the present invention and cannot be considered as limiting the scope of implementation of the present invention. All equivalent changes and improvements made according to the scope of the application of the present invention should still fall within the scope covered by the patent of the present invention.
