The sinking and lifting of the positioning frame require a negative pressure system, and the underwater alignment and installation construction of the suction pump is particularly important.

[0003] In the related art, the commonly used method for underwater alignment and installation construction of the auxiliary suction pump is underwater mechanical alignment by divers. This method requires divers to work underwater for a long time, and the underwater operation time of each diver is limited, resulting in low construction efficiency, long cycle, and high cost, which is not conducive to construction progress and cost control. Moreover, affected by various factors such as water flow, surges, and tides, the underwater operation construction of divers is difficult and risky, and it is only applicable to shallow waters with good wind and wave conditions and is not applicable to deep waters, with great limitations and large potential safety hazards during operation.

It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model. In addition, the technical features involved in the various embodiments of the present utility model described below can be combined with each other as long as they do not conflict with each other.

[0025] As Figures 1-4As shown in the figure, the utility model provides an underwater alignment and installation device for an auxiliary suction pump, which includes a lifting operation unit 1, a suction pump main body frame 2, a traction and guiding unit 3, a mounting base 4, an outer guiding unit 5 and a positioning unit 6. The lifting operation unit 1 includes a winch 11 and an upper platform 12. The winch 11 hoists and connects the four corners of the top of the suction pump main body frame 2, and lowers the suction pump main body frame 2 underwater. The traction and guiding unit 3 includes more than two groups of traction cables 301 and U-shaped shackles 304. The two ends of the traction cable 301 are vertically and fixedly connected to the upper platform 12 and the mounting base 4 respectively. One end of the U-shaped shackle 304 is fixedly arranged on the side of the suction pump main body frame 2, and the other end is hung on the traction cable 301, so that the suction pump main body frame 2 can be lowered smoothly. The outer guiding unit 5 is fixedly arranged on the top of the mounting base 4 to guide and limit the periphery of the suction pump main body frame 2, so that the suction pump main body frame 2 does not have axial deviation when descending along the vertical central axis. The positioning unit 6 includes a positioning column 61 fixedly arranged at the bottom of the suction pump main body frame 2 and a positioning tube 62 fixedly arranged at the corresponding position on the top of the mounting base 4. Through the guiding and limiting of the outer guiding unit 5, the positioning column 61 is aligned and inserted into the positioning tube 62 to complete the positioning and installation of the suction pump main body frame 2. The underwater alignment and installation device of the utility model can make the suction pump main body frame 2 be lowered smoothly and accurately positioned and installed on the mounting base 4 through various guiding and limiting measures, which can greatly shorten the underwater operation time, improve the safety of underwater operation, and reduce the safety risks and difficulties of underwater construction.

[0026] As Figure 1 , 3 shown, in the embodiment of the utility model, the lifting operation unit 1 is used for lifting and lowering the suction pump main body frame 2, and it includes a winch 11, an upper platform 12, a main steel wire rope 13 and a secondary steel wire rope 14. The winch 11 is used for vertically lifting or lowering the suction pump main body frame 2, and it is fixedly arranged on the upper platform 12. An opening is provided at the center of the upper platform 12 for passing the main steel wire rope 13. The upper end of the main steel wire rope 13 is connected to the winch 11, and the lower end is connected to the secondary steel wire rope 14 through a sling. There are four groups of secondary steel wire ropes 14. The upper ends of the four groups of secondary steel wire ropes 14 are connected to the main steel wire rope 13, and the lower ends are respectively connected to the four corners of the top of the suction pump main body frame 2.

[0027] As Figures 1-2 shown, in the embodiment of the utility model, the suction pump main body frame 2 is a frame structure, and its interior is used for loading and fixing the suction pump. While preventing the suction pump from being collided, the relatively regular frame structure facilitates guiding, limiting and positioning installation. Further, upper lifting lugs 201 are respectively arranged at the four corners of the top of the suction pump main body frame 2, and the lower ends of the four groups of secondary steel wire ropes 14 are connected to the upper lifting lugs 201, so as to suspend the suction pump main body frame 2 smoothly.

[0028] In the embodiment of the present utility model, the traction guiding unit 3 is used to guide and traction the descending trajectory of the suction pump main body frame 2 to prevent it from shifting and swaying during the lowering process. It includes a traction cable 301, a first turnbuckle 302, a second turnbuckle 303 and a U-shaped shackle 304. Among them, the first turnbuckle 302 and the second turnbuckle 303 are respectively arranged at the corresponding positions at the bottom of the upper platform 12 and the top of the installation base 4, and there are two groups or more of each; both ends of the traction cable 301 are fixedly connected to the first turnbuckle 302 and the second turnbuckle 303 respectively, and are tightened and straightened through the first turnbuckle 302 and the second turnbuckle 303; one end of the U-shaped shackle 304 is fixedly arranged on the side of the suction pump main body frame 2, and the other end is hung on the traction cable 301. When performing the traction guiding operation, the U-shaped shackle 304 arranged on the side of the suction pump main body frame 2 is hung on the traction cable 301, so that the suction pump main body frame 2 maintains a downward linear displacement along multiple traction cables 301, avoiding the offset and swaying of the suction pump main body frame 2 caused by underwater impact during the lowering process.

[0029] As Figure 4 shown, in the embodiment of the present utility model, the installation base 4 is placed at the bottom of the water and is used to install and support the suction pump main body frame 2. A support platform 401 is fixedly arranged at the center of its top. The top of the support platform 401 is in contact with the bottom of the suction pump main body frame 2 to support the suction pump main body frame 2 and lift it, preventing the suction pump main body frame 2 from contacting the bottom of the water and thus affecting the operation efficiency of the suction pump.

[0030] As Figure 4 shown, in the embodiment of the present utility model, the outer guiding unit 5 includes a limiting rod 51. There are two groups symmetrically arranged longitudinally and two groups symmetrically arranged transversely on the top of the installation base 4. Among them, the distance between the two groups of limiting rods 51 symmetrically arranged longitudinally is adapted to the length of the suction pump main body frame 2 to limit the longitudinal displacement of the suction pump main body frame 2; the distance between the two groups of limiting rods 51 symmetrically arranged transversely is adapted to the width of the suction pump main body frame 2 to limit the transverse displacement of the suction pump main body frame 2, so as to ensure that the suction pump main body frame 2 descends linearly in the vertical direction and avoid axial offset. Further, a guiding inclined rod 52 is fixedly arranged at the top of the limiting rod 51. The guiding inclined rod 52 inclines outward to introduce the offset suction pump main body frame 2 into the correct downward trajectory, avoiding the suction pump main body frame 2 being stuck by the limiting rod 51 and unable to descend when it is offset.

[0031] As Figures 1-2 and Figure 4As shown in the figure, the positioning unit 6 is used to position and install the suction pump main body frame 2 on the installation base 4, and it includes a positioning column 61 and a positioning tube 62. There are four groups of the positioning columns 61, which are respectively fixed at the four corners of the bottom of the suction pump main body frame 2; the positioning tubes 62 are fixed on the top of the installation base, and there are four groups of them, which are respectively located directly below the positioning tubes 62. Further, the positioning column 61 includes a column body 611 and a guiding cone 612 fixed at the bottom of the column body 611; the positioning tube 62 includes a tube body 621 and a guiding bell mouth 622 provided at the top of the tube body 621; the inner diameter of the tube body 621 is adapted to the outer diameter of the column body 611. By inserting the column body 611 into the tube body 621, the suction pump main body frame 2 is installed and positioned on the top of the installation base 4; through the guiding cone 612 and the guiding bell mouth 622, when the suction pump main body frame 2 has a slight deviation, the column body 611 can be accurately guided and inserted into the tube body 621.

[0032] When the underwater alignment and installation device of the present utility model is operating, the installation base 4 is pre-placed at the bottom of the water, and a guiding cable 301 is installed between the upper platform 12 and the installation base 4; the lower ends of the four groups of wire auxiliary ropes 14 are respectively connected to the four corners of the top of the suction pump main body frame 2, and the U-shaped shackles 304 provided on the side of the suction pump main body frame 2 are hung on the guiding cable 301; the winch 11 rotates and lowers the main wire rope 13, so that the suction pump main body frame 2 descends under the guiding action of the guiding cable 301; after descending and contacting the guiding inclined rod 52, the suction pump main body frame 2 is introduced into the correct lower track, and under the limiting action of the limiting rod 51, the suction pump main body frame 2 descends linearly along the vertical direction, avoiding axial deviation; through the guiding cone 612 and the guiding bell mouth 622, when the suction pump main body frame 2 has a slight deviation, the column body 611 can be accurately guided and inserted into the tube body 621, so as to install and position the suction pump main body frame 2 on the top of the installation base 4 and complete the installation operation.

[0033] The underwater alignment and installation device of the present utility model can greatly shorten the underwater operation time, improve the safety of underwater operations, reduce the safety risks and difficulties of underwater construction. Secondly, mechanical construction is adopted, which is less affected by sea conditions and water depth, and reduces the costs of machinery and personnel.

[0034] The underwater alignment and installation device of the present utility model enables the suction pump main body frame to be smoothly lowered and accurately positioned and installed through various guiding and limiting measures, reduces the construction difficulty, improves the operation efficiency and safety, and indirectly reduces the construction period and cost.

[0035] The underwater alignment and installation device of the present utility model, through the design of the outer guiding unit and the positioning unit, ensures that the suction pump main body frame can descend along the vertical central axis and be accurately positioned and installed, reducing the influence of environmental factors such as water flow, waves and tides on the construction.
