The following describes preferred embodiments of the present invention in detail with reference to the accompanying drawings 1-5:

in the preferred embodiment, vessel 6 is a marine survey vessel and the onboard operations equipment 8 is a multi-beam transducer. The wetwell 3 is a square channel structure on the vessel 6 that opens from the first hull deck 61 down to the bottom 5 of the vessel. The lower part of the square channel structure is a wet well wedge structure. In practical application, the structure can be a four-sided wedge, or can be a wedge with two opposite sides, and the inner included angle of the wet well wedge structure is beta. The preferred embodiment employs a four-sided wedge. The wet well wedge-shaped structure can be integrally manufactured with a wet well 3 vertical structure, can also be manufactured independently, and then is fixedly installed integrally with the wet well vertical structure in a sealing mode, and only the whole structure of the wet well 3 needs to be matched with the ship 6. The vertical rail mounting structures 33 are fixedly mounted on the opposite first side vertical surfaces 31 of the wet wells 3 in the four walls. In the preferred embodiment, two 316L rectangular steel pipes welded with at least four sets of adjusting blocks 34 (each adjusting block 34 is composed of two opposite wedge blocks, and the size of the adjusting block 34 can be changed through the relative movement of the two wedge blocks to adjust the position of the track mounting structure 33) are adopted and respectively and fixedly mounted on the first side vertical surface 31 of the wet well through the adjusting blocks 34 with adjustable height to form a guide rail on the side wall of the wet well 3, namely the track mounting structure 33, until the upper edge of the wedge structure of the wet well is close to. At the second hull deck 62 below the first hull deck 61 (the layer below the first hull deck 61 in the preferred embodiment), the wetwell 3 is squared off on the wetwell second side elevation 32. Thus, the inner cabin at the second hull deck 62 becomes a working equipment installation maintenance cabin 7 communicated with the wet well 3; in the preferred embodiment, the through-holes are single-sided, which is beneficial to the stability of the whole structure of the wet well 3. When the work equipment 8 is pulled through the work equipment installation and maintenance cabin 7 by the cable 22 in the wet well 3, the worker can perform maintenance or replacement of the work equipment 8 (the multi-beam transducer in the preferred embodiment) directly or with the aid of a pedal with fixed protection. The sea level in the wetwell 3 is the draft of the vessel 6.

It should be noted that: circular or elliptical shapes are also understood to mean mathematically polygonal shapes. If the wet well 3 is circular or elliptical, the rail mounting structures 33 are arranged on the side walls of two opposite generatrices of the wet well 3, and the penetrating positions of the equipment installation maintenance cabin 7 and the wet well 3 are rotated 90 on the generatrices⁰At the side walls of the wetwell 3.

The largest main structure of the conveyor 4 in the preferred embodiment is the equipment mounting platform main body 41, and a car structure with a square cross section is adopted. The overall structure of the car is made to fit the inner channel of the wetwell 3. A shoe guide device 43 is installed on a first opposite side vertical surface 411 (opposite to the wet well first side vertical surface 31 of the wet well 3) of the equipment installation platform body 41, and in the preferred embodiment, a U-shaped steel framework lining polytetrafluoroethylene is selected as the shoe guide device. The shoe guide 43 slides on the rail mounting structure 33 of the 316L rectangular steel pipe, and moves the car structure as the equipment mounting platform body 41 up and down in the wet well 3. The lower part of the car structure is provided with a wedge-shaped structure of the equipment mounting platform main body, the outer side of the wedge-shaped structure is basically matched with the inner side of the wedge-shaped structure of the wet well, and the outer included angle of the wedge-shaped structure is alpha. In practical application, the angle alpha is slightly smaller than the inner included angle beta of the wet well wedge-shaped structure, so that the lift car can smoothly descend to the bottommost part and is stably clamped in the wet well wedge-shaped structure. In the preferred embodiment, the inner edge of the minimum end of the wedge-shaped structure of the wet well is consistent with the outer edge of the minimum end of the wedge-shaped structure of the main body of the equipment mounting platform in size, namely the outer size of the lower opening of the wedge-shaped structure of the main body of the equipment mounting platform is consistent with the inner size of the lower opening of the wedge-shaped structure of the wet well, so that the car is ensured to sink to the lowest end of the wet well 3. The wedge-shaped structure of the main body of the equipment mounting platform can be manufactured integrally with the car structure or independently and then is fixedly mounted integrally with the car structure in a sealing manner.

It should be noted that: if the structure of the wet well 3 is not square, the cage structure can be square, and can also be matched with the cross section shape of the wet well 3. In any structure, alpha and beta are included angles of central lines of corresponding structures; the outer dimensions of the lower opening of the wedge-shaped structure of the equipment mounting platform body may also be consistent with the inner dimensions of a certain cross section of the wet well wedge-shaped structure close to the lower opening, as long as it is ensured that the multi-beam transducer (at least the active working part) of the working equipment 8 can be placed completely below the bottom 5 of the vessel.

In addition, in order to stabilize the multibeam transducer (working equipment 8) at the ship bottom 5 position, a counterweight 42 needs to be added to the car of the equipment installation platform main body 41. In the preferred embodiment, a steel plate is welded to the car as the counterweight 42. If different weights of the counterweight bodies 42 are needed by different working devices 8, the counterweight bodies 42 can be independently matched and fixedly connected with the device mounting platform main body 41 in a detachable mode so as to be convenient to replace. If the ship is used for a single purpose, the weight of the car can be enough, and the counterweight body 42 is not needed. At the bottom of the equipment mounting platform body 41, a mounting bracket 44 is attached, and at the lower end thereof, a mounting bracket lower interface 441 is provided that matches the interface on the working equipment 8. In the preferred embodiment, the mounting bracket 44 is welded directly to the lower part of the car, extending right to the bottom 5 of the ship, because the application is single. The mounting frame lower interface 441 is of an internal thread structure and is used in cooperation with a fastening bolt fixedly arranged at the upper end of the multi-beam transducer (the operation equipment 8). In practical application, other detachable fasteners such as a slotted screw are added to ensure that the multi-beam transducer is firmly installed. In order to mount the multiple working devices, it is conceivable to fasten the working devices 8 by using the flange fixed to the bottom of the device mounting platform body 41 as the mounting frame lower interface 441. The flange plate can be used as a universal interface to realize that different operation equipment 8 can be detachably and stably connected with the equipment mounting platform main body 41.

In the preferred embodiment, an electric hoist is used. The electric hoist integrates the power device 1 and the cable coiling device 21 in the hoisting device 2, wherein the steel wire rope is used as the cable 22. The cable guide device 23 is a pulley and is arranged on a bracket at the edge of the wet well 3; the wire rope is released by the turntable of the electric hoist, guided into the wet well 3 through the pulley, and hung on the equipment mounting platform main body hanging device 412 (steel ring welded on the car structure in the preferred embodiment) on the equipment mounting platform main body 41 through the hanging device 24 (steel hook is selected in the preferred embodiment) at the tail end. In practice, the power unit 1 and the lifting device 2 may be replaced by devices known in the art.

The hanging device 24 and the equipment mounting platform main body hanging device 412 can be hung by any tool structural member which can be used in a matching way in the field of engineering machinery, as long as the hanging hooks can be firmly connected with each other and can be firmly connected with the main body structures of the hanging device and the equipment mounting platform.

The wire rope of electric block hangs the car up-and-down motion in the wet well through the pulley, and when the car descends to 3 bottoms in the wet well, the multi-beam transducer of installation in the car bottom can carry out normal operation.

When the work of the multi-beam transducer is finished, the electric block is started, the steel wire rope is hung on the lift car in the wet well through the pulley to move upwards, and when the lift car is lifted to exceed the installation and maintenance cabin 7 of the operation equipment, the multi-beam transducer just enters the visual field of workers in the installation and maintenance cabin 7 of the equipment. The staff can approach the multi-beam transducer by means of the pedal and the like to remove the entanglement such as fishing net, net rope, seaweed and the like on the probe of the multi-beam transducer or replace the equipment.

The hull-based work equipment mounting system is very needed by many marine vessels, and different work equipment can be converted by simply replacing the mounting frame 44, the counterweight body 42 and other simple detachable components in the work equipment mounting system.

The ship 6 with the operation equipment installation system is built on the basis of the ship body, all operations on the operation equipment are completed on the ship deck or in the cabin, the labor intensity requirements of personnel are reduced, the operation safety and stability are improved, the sailing speed of the ship is improved, and the working efficiency is improved.
