Description

Technical Field

[0001] This utility model relates to the technical field of water surface support platform, and more specifically, it relates to a floating and mobile platform device. Background Technology

[0002] Currently, in complex waters, such as nearshore areas or rivers with large waves and currents and severe siltation, floating mobile platforms are commonly used as the base for underwater operations. However, such platforms typically face significant technical bottlenecks in complex waters with large waves and currents, as well as in silty environments.

[0003] (1) The platform has high movement resistance and is prone to sinking into silt. Traditional platforms use flat bases, which have a large ground area and strong adsorption force when moving in silt, causing the propeller to need to operate under overload. The shear resistance of silt causes the platform to tilt or even overturn. Especially in fluid silt, the platform sinking can easily lead to forced interruption of operations.

[0004] (2) The buoyancy adjustment response is lagging, and the reliance on a single air tank causes the buoyancy center to shift, resulting in poor platform stability in wind and waves; the buoyancy adjustment relies on external equipment and has a slow response.

[0005] Therefore, in order to solve the above-mentioned technical problems, this application proposes a floating and buoyant mobile platform device. Utility Model Content

[0006] To address the shortcomings of existing technologies, the purpose of this utility model is to provide a floating and mobile platform device that integrates buoyancy adjustment for floating and sinking, propeller-controlled movement, and the carrying of work equipment into an integrated platform structure, enabling floating and sinking control, movement, and equipment carrying functions in complex waters with wind, waves, and currents.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a floating mobile platform device, including a water unit, set on the shore, comprising a blower and a PLC control box;

[0008] The underwater unit, located in the water, includes a platform body, air tanks symmetrically arranged on both sides of the platform body, thrusters, sled-shaped bottom plates, and solenoid valve groups.

[0009] Each set of gas storage tanks is provided with an inflation port and an deflation port at both ends, and a gas transmission rigid pipe is provided between the inflation ports of the two sets of gas storage tanks.

[0010] The blower is connected to the underwater unit via a gas delivery hose and a gas delivery hard pipe to distribute the gas to the gas storage tanks on both sides.

[0011] The sled-shaped base plates are symmetrically arranged at the bottom of the platform body.

[0012] Preferably, the gas storage tank is a sealed pressure vessel, and the solenoid valve assembly includes valves respectively disposed at the gas filling port and the gas venting port of the gas storage tank.

[0013] Preferably, the sled-shaped base plate has anti-slip textures on its surface, and its front end has an upward-curving arc structure.

[0014] Preferably, the top of one end of the platform body is provided with an equipment mounting interface for installing a high-pressure water pump, a lighting system or a mechanical grab bucket.

[0015] Preferably, a waterproof adapter is provided between the gas delivery hose and the gas delivery rigid pipe.

[0016] Preferably, the thrusters are provided in eight groups, which are respectively arranged in the front, back, left and right directions of the main body of the platform and at both ends of the two groups of gas storage tanks on the side away from each other.

[0017] Preferably, an electrical control system is provided in the middle of the platform body, and the PLC control box is connected to the electrical control system via a cable to control the solenoid valve group and the thruster.

[0018] Preferably, the thrusters on the two sets of gas storage tanks are inclined downwards.

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] In this embodiment, the symmetrically arranged gas storage tanks are connected in parallel via gas supply pipes. A blower supplies gas to the solenoid valve at the filling end via a combination of gas supply hoses and gas supply pipes. The solenoid valve at the venting end independently controls the drainage. The dual-tank layout balances the buoyancy center, and the dual solenoid valves enable active control of filling and venting, replacing the inefficient mode of traditional single-tank drainage that relies on gravity, thus shortening the buoyancy adjustment time. Horizontal movement is controlled by a thruster, in which the tilting thruster provides an upward component force to counteract the sludge adsorption force.

[0021] The sled-shaped base plate structure features an upward-curving arc at the front end with anti-slip textures on the surface. The arc-shaped front end disperses the pressure of the silt, while the anti-slip textures increase lateral friction, thus solving the problem of silt adsorption and trapping caused by the large ground contact area of ​​the flat base.

[0030] like Figures 1-6 As shown, this utility model provides a floating and buoyant mobile platform device, comprising:

[0032] The PLC control box 12 has a built-in S7-1200 controller and an integrated power module to provide power to the underwater unit's equipment.

[0033] The underwater unit 2 includes: a platform body 21, which adopts a 304 stainless steel welded frame with dimensions of 4m × 2.5m, and an electrical control system 27 with a waterproof junction box in the middle;

[0034] The gas storage tank 22 consists of two sets of Φ600mm×3m pressure vessels, symmetrically welded to both sides of the platform body 21. Each set of gas storage tanks 22 has an inflation port 221 and an venting port 222 at both ends.

[0035] The solenoid valve assembly includes normally closed solenoid valves respectively disposed at the inflation port 221 and the deflation port 222 of the gas storage tank 22.

[0036] The sled-shaped base plate 24 is symmetrically located at the bottom of the platform body 21. It is made of polyurethane material, with a 15° upturned front end and a diamond-shaped anti-slip texture on the surface.

[0037] Thruster 23 uses eight brushless motor propellers, of which:

[0038] Four units are positioned at the four corners of the main platform 21;

[0039] Four units are located at both ends of the outer side of the gas storage tank 22, and are installed at a downward angle of 30°.

[0040] The equipment is equipped with interface 26, located on the top of the platform, which includes ISO standard bolt holes and waterproof aviation plugs for installing high-pressure water pumps, lighting systems, or mechanical grabs. The core of this embodiment is to provide a floating mobile platform. If dredging operations are required, professional equipment such as high-pressure water pumps can be mounted on the equipment via the equipment mounting interface 26. If salvage operations are required, lighting systems and grabs can be installed on the equipment. Relevant instruments and equipment can be customized according to needs. The connection relationship will not be described in detail.

[0041] Preferably, the blower 11 is connected to the underwater unit 2 via a gas delivery hose 3, and is connected to a gas delivery hard pipe 31 to distribute the gas to the gas storage tanks 22 on both sides;

[0042] The gas delivery hose 3 is made of PU material. One end is connected to the blower 11, and the other end is connected to the gas delivery rigid pipe 31 via a waterproof adapter.

[0043] The gas transmission pipe 31 is made of stainless steel and is connected in parallel to the filling ports of the gas storage tanks 22 on both sides.

[0044] The PLC control box 12 is connected to the electrical control system 27 via cable 4 and controls the solenoid valve group and the thruster 23.

[0045] When used for waterborne material transportation operations, the platform body 21 floats on the water surface, the solenoid valve group is closed, and the air tank 22 is filled with air; the propellers 23 are started through the PLC control box 12, and the eight propellers 23 work together to drive the platform to move; at this time, the operator stands in the middle of the platform body 21 and controls the direction of travel through the remote control;

[0046] When used for underwater dredging operations, when the platform floats on the water surface, the PLC control box 12 opens the solenoid valve of the vent port 222, and water is injected from the bottom of the air storage tank 22; the air in the tank is discharged, the buoyancy decreases, and the main body of the platform 21 sinks vertically to the bottom of the water, and the sled-shaped bottom plate 24 contacts the silt: the arc-shaped front end disperses the ground pressure, and the anti-slip texture inhibits side slipping; four horizontal thrusters 23 provide forward power, and four tilting thrusters 23 generate an upward component force;

[0047] Specialized tools such as high-pressure water pumps can be installed via the device's interface 26 and pointed towards the silt area. The water pump can be powered and control signals can be transmitted via the electrical control system 27.

[0048] After the operation is completed, the solenoid valve of the inflation port 221 is opened through the PLC control box 12. The blower 11 inflates the gas storage tank 22 through the gas supply hose 3 and then through the gas supply hard pipe 31. The gas compresses the water in the tank and discharges it from the vent port 222, increasing the buoyancy and causing the platform to float.
