Considering that the arrangement mode of the inflatable oil containment boom needs manpower or is arranged by means of ship external force, the arrangement efficiency is low, the arrangement angles of the oil containment booms in different water area environments are different, and the arrangement angles of the oil containment booms in the water areas with changeable directions and flow rates are difficult to change along with the change of the flow rates and the flow directions, the application provides an inflatable floating body device and a self-propelled oil containment boom, and a floating body assembly, two gas conveying devices and two exhaust pipes are arranged in the inflatable floating body device; the exhaust pipes are respectively arranged on one side of the floating body component in the length direction; two air cavities extending along the length direction of the floating body assembly are arranged in the floating body assembly, and each air cavity is communicated with different exhaust pipes; the two gas conveying devices are respectively arranged on the other side of the floating body component in the length direction and are respectively communicated with the two gas cavities, so that the inflation efficiency of the inflatable floating body can be effectively improved, the automatic control of the advancing direction of the inflatable floating body can be realized through inflation and/or exhaust flow control, the arrangement of the oil containment boom using the inflatable floating body can be effectively realized without artificial arrangement, the arrangement efficiency, the arrangement accuracy and the arrangement reliability can be effectively improved, and the self-navigation arrangement of the oil containment boom using the inflatable floating body can be effectively realized.

In one or more embodiments of the present application, referring to fig. 5, in order to further ensure the accuracy and reliability of the automatic control of the traveling direction of the inflatable floating body, the air chambers 400 are identical in shape and size, i.e., two air chambers 400 are axisymmetrically arranged. In practical applications, the joint between the two air cavities 400 is disposed at an angle substantially perpendicular to the horizontal plane, wherein substantially perpendicular means that the joint between the two air cavities 400 is at an angle of 90 ° ± 5 ° to the horizontal plane.

Based on the above, in order to enhance the application reliability of the inflatable floating device and to improve the convenience of the retrieval and storage of the inflatable floating device, in one embodiment of the inflatable floating device of the present application, the floating body assembly 100 may be composed of a plurality of floating bodies, as described in detail below:

The first float 110 is disposed at one side in a length direction of the float assembly 100, the second float 120 is disposed at the other side in the length direction of the float assembly 100, and the third floats 130 are disposed between the first and

second floats

110 and 120. That is, if there is only one third buoyant body 130, the third buoyant body 130 is connected between the first buoyant body 110 and the second buoyant body 120; if there are a plurality of third floating bodies 130, the third floating bodies 130 are sequentially connected, and then the third floating bodies 130 at one end of each of the sequentially connected third floating bodies 130 are connected to the first connection end of the first floating body 110, and the third floating bodies 130 at the other end of each of the sequentially connected third floating bodies 130 are connected to the second connection end of the second floating body 120.

It will be appreciated that the larger radius rounded end of the conical body member is the end surface having a larger radius than the other rounded end. In one example, the radius of the rounded end with the larger radius is the same as the radius of the end surfaces of the second float 120 and the at least one third float 130; the radius of the rounded end having the smaller radius is smaller than the radius of the end surface of the second float 120 or the at least one third float 130.

In an embodiment of the second buoyant body 120, referring to fig. 9, one end of the second buoyant body 120 is a mounting end 121, and the other end of the second buoyant body 120 is a second connecting end 122; both of the gas delivery devices 200 are disposed on the mounting end 121; the second connection end 122 is used to connect with the third floating body 130, so as to effectively improve the installation reliability of the gas delivery device 200.

In order to further improve the reliability of the connection between the individual floats, in one embodiment of the inflatable float device of the present application, a connection between the individual floats may be applied, in particular:

first connectors are sequentially connected among the first chambers 410 of the first, third and

second floats

110, 130 and 120, and the first connectors are communicated with the first chambers 410.

To further improve the application reliability of the inflatable float device and prevent the reverse flow of air, in one embodiment of the inflatable float device of the present application, a check valve 500 is provided at the connection between each of the first chambers 410; the check valves 500 are also disposed at the junctions between the second chambers 420, and all the check valves 500 are disposed in the same direction, so that the air flows from the tail portion of the floating body assembly 100 to the head portion thereof, and the backflow of the air from the head portion to the tail portion is prevented.

Based on the above, in order to further improve the application reliability of the exhaust pipe 300, in the embodiment of the exhaust pipe 300 in the inflatable floating body device of the present application, two exhaust pipes 300 are axisymmetrically disposed at one side in the length direction of the floating body assembly 100. The exhaust ends of the two exhaust pipes 300 are disposed near the connection between the first floating body 110 and the third floating body 130, and the angles between the two exhaust pipes 300 and the floating body assembly 100 are the same preset acute angle. Wherein the preset acute angle is between 30 and 60 degrees.

In addition, referring to fig. 11 and 12, an airbag 600 is respectively disposed at the connection of each of the two exhaust pipes 300 and the floating body assembly 100; the two air bags 600 are respectively communicated with the two air chambers 400 one by one, so that auxiliary support is provided for the exhaust pipe 300 through the elastic action, and the application reliability of the exhaust pipe 300 is improved.

In view of the above, in an embodiment of the present application, a stopper is respectively disposed at the connection between the exhaust pipe 300 and the floating body assembly 100 to improve the adjustability of the angle between the exhaust pipe 300 and the floating body assembly 100, and to improve the opening reliability of the inflatable floating body, thereby further improving the application reliability of the exhaust pipe 300.

In addition, the exhaust pipe 300 is a conical cylinder, and the circular end with the larger radius in the conical cylinder is communicated with the air cavity in the floating body assembly, and the circular end with the smaller radius in the conical cylinder is used for exhausting air, so that the pressure of the air at the outlet is increased conveniently.

Based on the above, in a specific application example of the inflatable floating body device of the present application, the first floating body, the third floating body and the second floating body may correspond to a head-end oil containment boom single body (1), a middle oil containment boom single body (several) and a tail-end oil containment boom single body (1), respectively, and the single bodies are connected with each other through a check valve. Meanwhile, the floating body assembly is evenly divided into two hollow air cavities, and the sections of the two air cavities are vertical to the water surface. And each air cavity is composed of various chambers which are connected in sequence along the length direction. In the present application, the first chamber and the second chamber are identical in shape and size.

Wherein, two cavities in the tail oil containment boom monomer are respectively connected with two air compressors, and air can be charged into the floating body component at any time.

Two exhaust pipes are respectively arranged in the middle chambers on the two sides of the head end oil fence monomer. The exhaust pipe is also connected with a cavity in the oil containment boom single body at the head end through a check valve, an air bag is arranged at the position close to the joint of each exhaust pipe and the floating body assembly, and the advancing position of the oil containment boom is arranged to be conical so as to reduce the resistance in the advancing process.

Based on this, in the inflation process, through changing the air inflation flow, the change of the gasbag volume between blast pipe and the body subassembly, the exhaust direction of blast pipe can be changed.

In addition, the included angle between the exhaust pipe and the floating body assembly ranges from 30 degrees to 60 degrees (controlled by the limiting piece), the direction of the included angle is opposite to the direction of the head end of the floating body assembly, and the exhaust pipe is in a conical cylinder shape, so that the pressure of gas at an outlet is increased conveniently.

The air compressor controls the speed of inflation and deflation in the air cavity of the floating body assembly. When the two air compressors are opened at the same speed, the inflating and exhausting speeds of the floating body component are equal, and when the air is exhausted, the floating body component is subjected to forward reverse thrust and can move forward; when the air compressors have different speeds, a speed difference is generated between the exhaust and inflation speeds of the floating body assembly, the traveling direction of the floating body assembly can be deviated to one side with a smaller speed, and the larger the speed difference is, the larger the deflection angle is. When the inflation rate is increased, the angle of the exhaust pipe is increased, the steering force applied to the floating body assembly is increased, and the direction conversion of the floating body assembly can be accelerated.

In one specific example, the present application also obtains the performance design parameters of the float assembly in the inflatable float device through experiments, as shown in table 2:

table 2:

based on the above, in order to effectively implement the deployment of the oil containment boom using the inflatable floating body, and effectively improve the efficiency, accuracy and reliability of the deployment, and further effectively implement the self-navigation deployment of the oil containment boom using the inflatable floating body, the present application further provides an embodiment of a self-navigation oil containment boom implemented by using all or part of the above-mentioned embodiments of the inflatable floating body device, referring to fig. 13, where the self-navigation oil containment boom 700 specifically includes the following contents:

In one example, the weight 740 may be a metal chain to enhance the weight effect.

One side of the floating body component in the length direction is a sealing end; the skirt 720 is connected to other regions of the float assembly than the sealed end.

Therefore, the self-propelled oil containment boom 700 provided by the embodiment of the application changes the exhaust flow at the exhaust pipe of the single oil containment boom at the head end by controlling the instantaneous flow of air in the cavity of the oil containment boom through the air compressor, so that the oil containment boom can obtain the recoil force of advancing and steering, the automatic navigation function of the oil containment boom is realized, and the quick arrangement of the oil containment boom is convenient to complete.

In order to further explain the scheme, the application further provides a specific application example of the self-propelled oil containment boom, which specifically comprises the following contents:

(1) the self-propelled oil containment boom is composed of a head end oil containment boom single body, a plurality of middle oil containment boom single bodies, a tail end oil containment boom single body, an intercepting net, a heavy chain, two exhaust pipes, two air bags, an air compressor and a check valve.

(2) The monomers are connected through check valves.

(3) The floating body comprises two hollow cavities, namely a cavity A and a cavity B, gas in each hollow cavity is provided by an air compressor, and the air compressor is connected with the tail-end oil fence single body.

(4) The skirt body is arranged below the floating body, the length of the skirt body is slightly smaller than that of the floating body, and the lower part of the top end of the conical column floating body is not connected with the skirt body of the oil containment boom; the intercepting net is linked below the oil containment boom skirt body and is connected with the counterweight chain.

(5) The head end oil fence monomer is connected with two exhaust pipes and two air bags.

(6) When the two air compressors work simultaneously and the air inflation rates are equal, the oil containment boom is inflated, so that the oil containment boom is in a full-filling state. And continuously inflating, wherein the air pressure in the cavity of the oil containment boom is greater than the external pressure, the two exhaust pipes begin to exhaust, the exhausted air impacts the water body to obtain a recoil force, and the oil containment boom automatically advances due to the fact that the recoil force applied to the two exhaust pipes acts on the oil containment boom to obtain two forward component forces in the same direction and two rotating forces in opposite directions and offset each other.

(7) And adjusting the inflation rates of the two air compressors to make the inflation rates of the two air compressors unequal, so that the sailing direction of the oil containment boom can be deflected. If the inflation rate of the cavity A is increased to be larger than that of the cavity B, the gas exhausted from the exhaust pipe A impacts the water surface to obtain a steering force, so that the oil containment boom deflects towards the cavity B, and the autonomous turning of the oil containment boom is completed.

(8) When the inflation rate of the cavity A is increased, the inflation quantity of the air bag A is increased, so that the angle between the exhaust pipe A and the oil containment boom is increased, and the steering component acting on the oil containment boom is strengthened. When the inflation rate of the cavity A is reduced, the gas pressure in the air bag A is gradually higher than the pressure in the cavity A, the volume of the air bag A is reduced, the included angle between the exhaust pipe A and the oil containment boom is reduced, and the advancing acting force acting on the oil containment boom is strengthened.

(9) The angle between the exhaust pipe 300 and the floating body assembly 100 is maintained within the range of 30-60 degrees, so that the oil containment boom can always obtain forward force, and the force analysis and the exhaust pipe rotation angle of the exhaust pipe 300 on the floating body assembly 100 are shown in fig. 14.

(10) And after the oil containment boom is laid, fixing the head end of the oil containment boom, and stopping the air compressor.

It can be known from the above description that the self-propelled oil containment boom provided by the embodiment of the application controls the instantaneous flow of air in two hollow cavities of the oil containment boom by using the air compressor, and changes the exhaust flow of the exhaust pipes at the two ends of the single body of the oil containment boom at the head end, so that the oil containment boom can obtain the recoil force of advancing and steering, wherein the change of the advancing force and the recoil force can be realized by changing the flow rate of the air compressor and controlling the rotation angle of the exhaust pipes by the air bags, the automatic navigation function of the oil containment boom is realized, and the quick arrangement of the oil containment boom is conveniently completed.
