Description

Technical Field

[0001] This invention belongs to the field of maritime traffic safety facilities and relates to an intelligent self-floating interception buoy. Background Technology

[0002] In recent years, due to the frequent occurrence of ship collisions with bridges, bridge collision prevention has received increasing attention. Because of the large number of piers on non-navigable bridges, installing individual collision prevention facilities is costly. Therefore, the current approach for collision prevention on long-distance non-navigable bridges mainly involves setting up interception systems upstream and downstream. The pontoons, as a crucial unit of the interception system, primarily connect the interception cables, ensuring the interception net floats above the water surface. When a ship collides with and drags the interception net, the anchorage beneath the pontoons maintains the shape of the entire interception system. Some interception systems are configured to use pontoons to drag the anchorage to dissipate energy.

[0003] There are currently various types of pontoons in use, including double-pontoon floating base type, ship type, cylindrical type, etc.

[0004] Based on the current situation of the pontoons, there are three main problems: (1) Although the stability of the pontoons under the action of wind and waves was considered in the design, since most of the components of the pontoons are above the water surface, after the typhoon, the pontoons and the interception net are damaged to varying degrees, such as serious displacement of the pontoons, damage to components, and entanglement of the interception net; (2) The entire interception system is above the water surface, which affects the landscape, and the components are easily aged due to the combined action of seawater and ultraviolet rays; (3) At present, the interception net and the pontoons are mostly operated independently and require regular inspection. The specific interception situation can only be found during the inspection, resulting in low work efficiency and high operation and maintenance costs.

[0005] Therefore, in order to reduce the impact of typhoons and waves on the pontoon components, slow down the aging of the pontoon components, and optimize the aesthetics of the interception pontoons, a new intelligent self-floating interception pontoon is urgently needed to solve the above problems. Summary of the Invention

[0006] In view of this, the purpose of this invention is to provide an intelligent self-floating interception pontoon that solves the problems of poor wind and wave resistance, poor aging resistance, poor landscape, and high operation and maintenance costs of existing pontoons.

[0007] To achieve the above objectives, the present invention provides the following technical solution:

[0008] A smart self-floating interception pontoon includes an upper main body, a truss structure, a counterweight chamber, and an anchoring system; the upper main body includes an external part, a closed chamber, an airbag chamber, a compressed gas chamber, and a control center;

[0009] The external components include a radar system, a warning system, and a video surveillance system, used for collecting and responding to external signals;

[0010] The enclosed compartment is a sealed structure that provides buoyancy for the pontoons during normal operation;

[0011] The airbag cabin is equipped with airbags, and the overall buoyancy of the structure is controlled by the expansion and contraction of the airbags.

[0012] The compressed gas chamber is used to store high-pressure gas, which is used to inflate the airbag, stabilize the safety valve pressure, and pressurize the airbag.

[0013] The control center controls the inflation and deflation of the airbag chamber and the compressed gas chamber through a two-way valve, thereby controlling the buoyancy of the float.

[0014] The truss structure is used to connect the upper part of the pontoon, the counterweight hopper, and the anchoring system;

[0015] The counterweight compartment is used to adjust the overall counterweight of the pontoon to meet the draft requirements, lower the center of gravity of the pontoon, and improve the stability of the pontoon.

[0016] The anchoring system is used to fix the range of motion of the pontoon within a certain area.

[0017] Preferably, the radar system is used to detect objects within a designated area and feed the results back to the control center; the warning system is equipped with warning lights and horns, the warning lights are used to alert navigating vessels during normal operation, and the flashing brightness and frequency are increased during protection mode; the video surveillance system is used to monitor the surrounding area.

[0018] Preferably, the enclosed chamber is equipped with a power supply pipe, a pressurization channel, an exhaust pipe, and a maintenance channel.

[0019] Preferably, the airbag is equipped with an inflation port, an exhaust port, and a safety valve.

[0020] Preferably, the compressed gas chamber is equipped with an inflation valve, a safety valve, and a pressurization valve, which are connected to the airbag, the exhaust pipe, and the pressurization equipment through pipelines to realize airbag inflation, safety valve pressure stabilization, and air chamber pressurization.

[0021] Preferably, the anchoring system includes an anchor chain and a concrete anchor.

[0022] Preferably, the control center includes a signal processing system, a control panel power supply, a two-way valve, and a valve controller;

[0023] The signal processing system is respectively connected to the valve controller, the radar system, the warning system and the video monitoring system. It comprehensively judges according to the signals collected by the radar system, the warning system and the video monitoring system, and then issues an instruction to the valve controller. The valve controller is connected to the two-way valve and controls the opening and closing state of the two-way valve according to the instruction issued by the signal processing system. The power supply supplies power to the signal processing system, the radar system, the warning system, the video monitoring system, the valve controller and the two-way valve.

[0024] Preferably, the signal processing system is also connected to the background management system to realize the remote control function.

[0025] Preferably, the control method of the buoy is as follows:

[0026] Under normal operation, the airbag is folded and the buoy is located at the deep water level. The radar system and the video system monitor the monitoring area simultaneously, and the warning light is always on to remind passing ships.

[0027] When the radar system or the video system detects that a ship enters the monitoring area, the warning light of the buoy flashes, and the horn reminds the ship that it is about to enter the protection area. At the same time, the signal is transmitted to the control center, and it continuously monitors and judges whether the ship stops or leaves the monitoring area. If the ship stops, the warning system continuously reminds. If the ship leaves the monitoring area, the warning system stops reminding. If the ship continues to move forward and enters the warning area, the control center will start the valve controller, and the inflation channel of the two-way valve will be opened, and the airbag will start to inflate. At the same time, the buoy starts to float until the airbag is fully inflated and the inflation valve is closed, and the buoy floats to the shallow water level to intercept the ship.

[0028] After the interception is successful, it is necessary to eliminate the hidden danger and make the ship leave the monitoring area. After the ship leaves, the controller starts, and the exhaust channel of the two-way valve will be opened. The airbag starts to exhaust under the action of the external water pressure and gradually sinks until the airbag sinks to the deep water level.

[0029] Preferably, the control center is divided into two situations according to the different order of radar signal and video signal recognition. The first situation is:

[0030] When the video monitoring system recognizes that there is a foreign object entering the monitoring area through image comparison:

[0031] Step 1: Signal reception = [A1, A2, A3], where A1 is the video foreign object signal, A2 is the size of the foreign object estimated by the scale, and A3 is the foreign object coordinate.

[0032] Step 2: Signal processing: Judge whether A2 exceeds the system preset foreign object size limit value A*; if A2 < A*, return to Step 1; if A2 > A*, proceed to Step 3;

[0033] Step 3: Issuing an instruction: The signal processing system sends a Level 1 warning instruction to the warning system and sends the A2 coordinates to the radar at the same time;

[0034] Step 4: Signal reception: The radar system adjusts the angle to locate the position of the foreign object and continuously returns the distances B1, B2, …, Bn of the relative position of the foreign object;

[0035] Step 5: Signal processing: If Bn > D, continue with Step 4; if Bn < D, it is considered that the foreign object has entered the warning area, and then proceed to Step 6; where D is the set warning distance of the radar;

[0036] Step 6: Issuing an instruction: The signal processing system sends a Level 2 warning instruction and a buoy floating-up instruction to the warning light and the horn. The valve controller is opened, the inflation channel of the two-way valve is opened, and after inflating for the set time, the controller is closed and the buoy floats up; The process is completed.

[0037] The second case is:

[0038] When the radar system detects through the video monitoring area and a foreign object enters the video monitoring area:

[0039] Step 1: Signal reception = [B(x, y), B1], where B(x, y) is the coordinate of the foreign object position and B1 is the relative distance of the foreign object;

[0040] Step 2: Issuing an instruction: The signal processing system sends the foreign object position coordinates to the video monitoring system;

[0041] Step 3: Signal reception: The video monitoring system adjusts the angle to locate the position of the foreign object and returns the foreign object signals [A2, A3];

[0042] Step 4: Signal processing: Determine whether A2 exceeds the preset foreign object size limit A* of the system; if A2 < A*, return to Step 1; if A2 > A*, proceed to Step 5;

[0043] Step 5: Signal reception: The radar system continuously returns the distances B1, B2, …, Bn of the relative position of the foreign object and performs Steps 5 and 6 of the first case;

[0044] After removing the foreign object and ensuring the safety of the warning area, the signal processing system receives the sinking instruction sent by the remote platform. The valve controller is opened, the exhaust channel of the two-way valve is opened, the gas in the airbag is discharged, the buoy gradually descends, and after the set time, the controller is closed and the exhaust channel is closed.

[0045] The beneficial effects of this invention are as follows: The upper part of the pontoon is submerged underwater, with only the top platform exposed to provide additional buoyancy and accommodate warning lights and other facilities. Simultaneously, to achieve remote control, an intelligent triggering system and a buoyancy system are configured. When the interception function is needed, the pontoon surfaces, clears the obstacle, and then sinks back to its original position for reuse, minimizing the impact of the interception system on the landscape. The pontoon of this invention has the advantages of good wind and wave resistance, good aesthetics, and ease of maintenance.

[0059] Please see Figures 1 to 8 The pontoon of this invention consists of an external part, a closed compartment, a control center, an airbag compartment, a compressed gas compartment, a truss structure, a counterweight compartment, and an anchoring system, as shown below. Figure 1 As shown. The outer shell of the pontoon is made entirely of steel with good corrosion resistance or rust prevention treatment.

[0060] The external components include a radar system, a warning system, and a video surveillance system, primarily used for acquiring and feeding back signals from the outside world. The radar system detects objects within a designated area and sends the results back to the control center; the warning system includes warning lights and a horn; the warning lights alert navigating vessels during normal operation, and their flashing brightness and frequency increase during protection mode; the video surveillance system monitors the surrounding area.

[0061] The enclosed compartment is a sealed structure that provides buoyancy for the pontoons in normal operation, and is also equipped with power line pipes, pressurization channels, exhaust pipes, and maintenance channels.

[0062] The control center is the core of the entire ascent system, such as Figure 6 As shown, the main components installed include a control panel power supply, a two-way valve, a valve controller, and pipelines.

[0063] The airbag compartment is equipped with airbags, and the overall buoyancy of the structure is controlled by the expansion and contraction of the airbags. The airbags are equipped with inflation ports, vent ports, and safety valves. The airbags are made of rubber or five-layer mesh material.

[0064] The compressed gas chamber is a pressure-resistant steel structure with its outer walls filled with concrete, used to store high-pressure gas. It is equipped with an inflation valve, a safety valve, and a pressurization valve, which are connected to the airbag, exhaust pipe, and pressurization equipment via pipelines to achieve airbag inflation, safety valve pressure stabilization, and chamber pressurization. Generally, an inert gas, such as nitrogen, is used for the compressed gas.

[0065] The truss structure is used to connect the upper part of the pontoon, the counterweight tank, and the anchoring system.

[0066] The counterweight compartment is used to adjust the overall weight of the pontoon to meet the draft requirements, lower the center of gravity of the pontoon, and improve the stability of the pontoon.

[0067] The anchoring system, consisting of anchor chains and concrete anchors, is used to fix the movement range of the pontoon within a certain area.

[0068] The design principles of airbags and compressed gas chambers are as follows:

[0069] like Figures 4-5 As shown, when the buoy rises from deep water to shallow water, the volume of water displaced by the airbag is V1 = the volume change of the buoy V, and the volume of the compressed air chamber is V2. According to Boyle's Law, at room temperature, the pressure of the compressed air required to compress the air chamber for one airbag deployment is as follows:

[0070]

[0071] Here, P1 is the pressure required for the airbag to deploy, which is atmospheric pressure plus water pressure. Therefore, the airbag can be inflated and floated when the pressure in the compressed gas chamber is greater than P2.

[0072] like Figures 7-8 As shown, the working process of the float of the present invention is as follows:

[0073] Under normal operating conditions, the airbags fold down, and the buoys are positioned in deep water. The radar and video systems simultaneously monitor the area, and warning lights remain constantly illuminated to alert passing vessels.

[0074] When a radar or video system detects a vessel entering the monitoring area, the buoy warning lights flash, and the horn alerts the vessel to its impending entry into the protected area. Simultaneously, the signal is transmitted to the control center, which continuously monitors and determines whether the vessel stops or leaves the monitoring area. If the vessel stops, the warning system (warning lights and horn) continues to alert; if the vessel leaves the monitoring area, the warning lights and horn cease. If the vessel continues and enters the warning area, the control center activates the valve controller, opening the inflation channel of the double-way valve, inflating the airbag, and simultaneously causing the buoy to rise until the airbag is fully inflated. The inflation valve then closes, and the buoy rises to a shallow water level, thus intercepting the vessel.

[0075] After a successful interception, potential hazards must be eliminated to allow the vessel to leave the monitored area. Once the vessel has left, the valve controller will activate, opening the exhaust channel of the two-way valve. The airbag will then begin to release air under external water pressure and gradually sink until it reaches the deep water level.

[0076] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
