Detailed Implementation

[0039] The principles and features of this utility model are described below with reference to the accompanying drawings. The examples given are only for explaining this utility model and are not intended to limit the scope of this utility model.

[0040] like Figures 1 to 6 As shown, a dual-body foldable underwater explorer includes a floating body component 1, a platform 2, an underwater work cabin 3, a positioning connection mechanism 4, a lifting and adjusting mechanism 5, a control component 6, and a sunshade 7. The sunshade 7 is fixed above the platform 2 by a support rod and covers the seating area on the platform 2. The platform 2 is provided with a platform railing 20 at its edge.

[0041] The four corners of the floating body component 1 are detachably equipped with tires via bolts, which solves the pain point of the difficulty of transferring traditional underwater exploration equipment to land. During transportation, there is no need to rely on large lifting equipment. The equipment can be moved directly by the tires or transported in conjunction with other vehicles. When operating on water, the tires can be removed (or left in place without affecting buoyancy) to avoid the tires interfering with the equipment's attitude on water, thus balancing transportation convenience and navigation stability.

[0042] The floating body component 1 is used to support the entire explorer and float it on the water surface, providing buoyancy support for the entire device and ensuring that the device floats stably on the water surface. The platform 2 of the floating body component 1 provides a space for personnel to stand, lie down and rest, and has reserved sufficient redundant space to carry a variety of auxiliary equipment, such as shooting equipment and detection instruments, which are suitable for diverse scenarios such as underwater sightseeing, scientific research and exploration, and leisure and entertainment.

[0043] Platform 2 is fixed above the floating body component 1. The underwater work cabin 3 is detachably connected to the floating body component 1 through a positioning connection mechanism 4. The underwater work cabin 3 is used to accommodate personnel for underwater exploration operations. Under the action of the positioning connection mechanism 4, the underwater work cabin 3 can maintain a preset underwater depth to avoid the operation personnel being affected by waves and undercurrents. When the operation personnel are sitting in the cabin, the water level is above their heads. If they suddenly feel unwell, they can quickly stand up and emerge from the water. This not only prevents choking on water when too shallow, but also avoids the trouble of ear pressure equalization when too deep, greatly improving the safety of shallow diving exploration, photography, sightseeing and other operations.

[0044] The lifting adjusting mechanism 5 is installed on the platform 2 and is connected with the underwater operation cabin 3, and is used for driving the underwater operation cabin 3 to lift to switch the operation state and the sailing state; the lifting adjusting mechanism 5 can drive the underwater operation cabin 3 to lift, and the cabin body is sunk to a preset depth during operation to meet the underwater operation requirement; and the cabin body is lifted to be close to the platform 2 during sailing, so that the water resistance is obviously reduced, the sailing efficiency is improved, the folding characteristic of the equipment is realized, and the sailing energy consumption and the occupied space during transportation are reduced.

[0047] In addition, the symmetrical layout of the double-body pontoons does not shield the middle area below the platform 2, reasonable space is reserved for installation of the ladder 42 and the basket 30 and personnel passing, personnel can safely go back and forth between the bench 31 and the basket 30 through the ladder 42, and the buoyancy function of the floating body is not disturbed; the outer side of the pontoon can be additionally provided with a fender, and the symmetrically arranged fender can comprehensively cover the easy-collision areas on both sides of the equipment, reduces collision damage during berthing or sailing, and guarantees that the buoyancy performance of the floating body is not affected.

[0088] Lifting of the hanging basket 30 reduces resistance: the operator turns the winch disc 51, and the steel wire rope drives the hanging basket 30 to slowly rise until the hanging basket 30 is close to the bottom of the platform 2, completely detached from the underwater environment (or only a small amount of immersion), and the water resistance during sailing is minimized; turn the shaft locking piece of the winch disc 51 to lock the position of the winch disc 51 to prevent the hanging basket 30 from falling due to shaking during sailing;

[0089] Sailing control and safety protection: the operator is located in the water driving position, and drives the equipment to sail by controlling the controller to control the propeller 63, the symmetrical structure of the double body float ensures the stability of the sailing posture, and the outer anti-collision strip can reduce the damage caused by slight collision during landing or sailing; the platform guardrail 20 ensures the safety of the standing personnel, and the sunshade 7 continues to provide sunshade and rain protection, realizing long-distance safe transfer.

[0090] S5: storage stage

[0091] Equipment landing and fixing: the equipment is stably landed on the shore by controlling the propeller 63, and the position of the equipment is fixed by using a rope or an anchor, so as to avoid the equipment from drifting due to water flow impact;

[0092] Component disassembly and arrangement: the connection between the winch disc 51 hook and the hanging basket 30 is released, and the sunshade 7 is removed; the wear condition of each component is checked, and the easily worn components such as the ladder 42, the pin 43 and the winch mechanism are cleaned and maintained; the front bearing boom 40, the rear bearing boom 41 and the hanging basket 30 are adjusted to a compact state, so as to reduce the overall space occupied by the equipment;

[0093] Land storage and transfer: the driving or driven tires are reinstalled, and the equipment is transferred to the storage area by manual or mechanical traction, so as to complete the closed loop of the whole working process.

[0094] In addition, it should be noted that the components not described in detail in the present application are prior art.

[0095] The above is only a preferred embodiment of the present application, and is not used to limit the present application, and any modification, equivalent replacement, improvement, etc. made within the spirit and principles of the present application shall be included in the protection scope of the present application.
