Description

Technical Field

[0001] The invention relates to the technical field of bridge protection, in particular to a bridge anti-collision airbag interception device. Background Art

[0002] Bridges are an important land transportation line. Bridges located on the ocean or rivers are densely distributed. There are countless ships of various tonnages and models. Such criss-crossing traffic routes are bound to intersect, that is, collisions between ships and bridges will occur, especially bridge piers. However, as an important component structure of the bridge, the collision of the pier by the ship will inevitably cause damage to the entire bridge structure, thereby rendering the bridge inoperative and paralyzing the road network, and even causing a large number of casualties, seriously threatening public safety.

[0003] At present, bridges are mainly protected from collision by anti-collision fenders and pile-type anti-collision mechanisms. However, although the former has the advantages of simple structure and low maintenance cost, the tonnage of the ship it resists collision is relatively small; although the latter is not limited by the type of piers and the tonnage of the colliding ship, it is difficult to construct and will reduce the clearance space for ships to pass, that is, after the pile-type anti-collision mechanism is installed around the piers, the distance between the piers available for ships to pass is reduced. Summary of the invention

[0004] In view of this, the present invention provides a bridge anti-collision airbag interception device, which not only retains sufficient clearance space but also can resist the impact of ships, thereby solving the problem that bridges and piers are difficult to be effectively protected when they are hit.

[0005] In order to achieve the above object, the present invention provides a bridge anti-collision airbag interception device, comprising:

[0006] A receiving assembly, the receiving assembly is installed on the outer side wall of the pier, and a cavity is formed inside the receiving assembly;

[0007] An airbag anti-collision unit, the airbag anti-collision unit includes a first airbag unit, the first airbag unit is installed in the cavity; the first airbag unit includes at least one first airbag layer, the first airbag layer includes a plurality of first airbags that are interconnected, at least one of the first airbags in the first airbag layer is connected to an external air source, so that the plurality of first airbags expand after being inflated and pop out of the cavity.

[0008] The bridge anti-collision airbag interception device provided by the present invention has the following beneficial effects: a storage component is installed on the outer side wall of the pier, and the uninflated first airbag unit is stored in the cavity of the storage component, so that the bridge anti-collision airbag interception device in the unactivated state can always ensure the clearance space between the piers. When a ship is about to collide with the pier, the first airbag is inflated to quickly form a multi-layer connected airbag anti-collision surface, thereby absorbing and dissipating the impact force when the ship hits the pier, protecting the pier and avoiding serious damage caused by the breakage of the pier.

[0016] The principles and features of the present invention are described below in conjunction with the accompanying drawings. The examples given are only used to explain the present invention and are not used to limit the scope of the present invention. The present invention is described in more detail by way of example with reference to the accompanying drawings in the following paragraphs. The advantages and features of the present invention will become clearer according to the following description and claims. It should be noted that the drawings are all in a very simplified form and are not in precise proportions, and are only used to conveniently and clearly assist in explaining the purpose of the embodiments of the present invention.

[0017] like Figure 1-3As shown, the bridge anti-collision airbag interception device includes a storage component 1 and an airbag anti-collision unit 2. The storage component 1 is installed on the outer wall of the pier 3 (the pier 3 in this embodiment is a rectangular pier, and of course it can also be a pier 3 of other shapes, such as a cylindrical pier, etc.). The outer wall of the pier 3 refers to the outer wall that may collide with the pier 3 during the voyage of the ship, that is, the four side faces of the pier 3 and the four side edges of the pier 3 in this embodiment. A cavity is formed inside the storage component 1;

[0018] The airbag anti-collision unit 2 includes a first airbag unit 21, which is installed in the cavity of the storage component 1; the first airbag unit 21 includes at least one first airbag layer 211. In this embodiment, the first airbag layer 211 is three layers, and each first airbag layer 211 is connected to each other. The connection method can be adhesive or sewing, etc., to ensure that each first airbag layer 211 is connected after inflation and forms a multi-layer airbag anti-collision surface (that is, the surface where the ship directly contacts the pier 3 when a collision occurs). The first airbag layer 211 includes a plurality of first airbags 21 that are interconnected. 1a, at least one first airbag 211a in the first airbag layer 211 is connected to an external air source, so that multiple first airbags 211a pop out of the cavity after being inflated, thereby forming a layer of airbag anti-collision surface. Specifically, the filled air quickly diffuses after entering the first airbag 211a, so that the entire layer of first airbags 211a is filled with gas, and then the multiple layers of first airbag layers 211 all diffuse and expand after being inflated and pop out of the cavity of the storage component 1 to form a multi-layer airbag anti-collision surface, thereby absorbing and dissipating the impact force during a ship collision, thereby avoiding the collapse of the bridge pier caused by the collision of the ship.

[0019] It can be understood that in order to facilitate the air source to inflate the interior of the first airbag 211a and in order to avoid the air source occupying the clear space for ship navigation, during installation, the air source can be fixedly installed on the abutment at the upper end of the pier 3 or the side of the bridge. In order to facilitate the inflation of the first airbag 211a, components such as a switch valve can be arranged between the air source and the first airbag 211a. The switch valve is preferably an electromagnetic switch valve, and the switch valve is also fixedly installed on the abutment at the upper end of the pier 3 or the side of the bridge to avoid occupying the clear space.

[0020] It should be noted that the collision of a ship with a bridge pier is warned based on the existing early warning system. Displacement sensors can be installed on the side walls of the pier. The GPS in the early warning system is used to capture the positions of ships around the pier and the relative positions between the ships, as well as information such as the speed of each ship and send the collected signals to the forecast control center. The ship's heading, speed and the distance between the pier and the ship measured by the displacement sensor are used to determine whether a high risk of collision is reached. If the high risk preset by the forecast control center is reached, the switch valve is activated through a wireless network signal to allow the high-pressure air in the air source to quickly fill the first airbag unit 21. After receiving the air, the first airbag unit 21 expands rapidly and pops out of the storage component 1, causing the ship to collide with the first airbag unit 21, thereby protecting the pier. Of course, the switch valve can also be activated manually or by other means to complete the inflation process of the first airbag 211a by the air source.

[0021] Preferably, the gas source is a high-pressure gas cylinder or an air compressor.

[0022] For a better explanation of the storage component 1, please continue to refer to Figure 4 The storage assembly 1 includes a storage rack 11, a storage cover 12, a push piece 13 and a storage bag 14. The storage rack 11 is a plate-like structure with a hollow interior, and a plurality of through holes 111 are formed on the outer side walls around the storage rack 11. The left end of the storage rack 11 is fixedly connected to the outer side wall of the pier 3, and the right end of the storage rack 11 is formed with an opening adapted to the storage cover 12. The storage cover 12 can be slidably installed on the storage rack 11 to open or close the opening at the right end of the storage rack 11; the push piece 13 and the storage bag 14 are both installed inside the storage rack 11, the left end of the push piece 13 is fixedly connected to the inner side of the left end of the storage rack 11, the right end of the push piece 13 is fixedly connected to the storage bag 14, and the uninflated first airbag unit 21 is installed inside the storage bag 14; When the first airbag unit 21 starts to inflate, the storage cover 12 is first opened to open the opening at the right end of the storage rack 11. During the inflation of the first airbag unit 21, the push member 13 is activated, and the push rod in the push member 13 extends to the right and pushes the storage bag 14 to move to the right, thereby pushing the inflated first airbag unit 21 placed inside the storage rack 11 out of the opening at the right end of the storage rack 11, thereby accelerating the inflation process of the first airbag unit 21 (because the internal space of the storage rack 11 is limited, if the first airbag unit 21 is always inflated inside the storage rack 11, the inflation process of the first airbag unit 21 will be slowed down due to the limitation of the storage rack 11, and it is easy to get stuck in the through hole 111 after inflation, and it cannot play a better role in collision prevention). It should be noted that the sliding action of the storage cover 12 to open the right end opening and the action of the push member 13 extending and pushing to the right can be achieved by pneumatic methods such as cylinders. Of course, other methods can also be used, which will not be repeated here.

[0023] For a better explanation of the first airbag 211a, please continue to refer to Figure 5 Each first airbag 211a includes a main airbag a1 and a plurality of auxiliary airbags a2. The main airbags a1 in two adjacent first airbags 211a on the same layer are interconnected, and the auxiliary airbags a2 in two adjacent first airbags 211a on the same layer are interconnected. It should be noted that the interconnection between the two adjacent main airbags a1 on the same layer and the two adjacent auxiliary airbags a2 on the same layer is to enable each layer of the first airbag layer 211 to be deployed more quickly. Of course, the main airbags a1 adjacent to different layers and the auxiliary airbags a2 adjacent to different layers can also be interconnected. The main airbag a1 outside of at least one first airbag 211a is connected to the auxiliary airbag a2 of the first airbag 211a. Connected to an air source, at least one auxiliary airbag a2 in the first airbag 211a is connected to an external air source, the main airbag a1 is in a prism shape, and multiple auxiliary airbags a2 are respectively installed on the side edges of the main airbag a1, and every two adjacent auxiliary airbags a2 are connected to each other. When the first airbag 211a is inflated, multiple auxiliary airbags a2 are first inflated (their internal inflation space is smaller). During the inflation and expansion process of the auxiliary airbag a2, the auxiliary airbag a2 located at the side edges of the main airbag a1 drives the side edges of the main airbag a1 to expand, so that the main airbag a1 when not inflated or just inflated is quickly formed, that is, it changes from a deflated state to the prism shape in the figure, thereby accelerating the inflation process of the main airbag a1.

[0024] Preferably, the connecting surface between every two adjacent auxiliary airbags a2 is spherical, so as to provide a smooth transition between the auxiliary airbags a2.

[0025] Preferably, the main airbag a1 is in a quadrangular prism shape, the auxiliary airbag a2 is in a cylindrical shape, the number of the auxiliary airbags a2 is 12, and the 12 auxiliary airbags a2 are respectively installed on the 12 side edges of the main airbag a1.

[0026] For a better explanation of the airbag anti-collision unit 2, please also refer to Figure 1 , Figure 2 and Figure 6In order to better protect the side edges of the rectangular pier 3, the airbag anti-collision unit 2 also includes a second airbag unit 22. The first airbag unit 21 and the second airbag unit 22 are independent of each other and are respectively installed in the cavities of their corresponding storage components 1. The storage component 1 corresponding to the first airbag unit 21 is fixedly installed on the outer walls around the pier 3, and the storage component 1 corresponding to the second airbag unit 22 is fixedly installed on the side edges of the pier 3. Preferably, in order to facilitate the fixed connection between the storage component 1 and the side edges of the pier 3, the two sides of the storage frame 11 in the storage component 1 can be fixedly connected to the two adjacent side edges. The second airbag unit 22 is installed in the cavity of the storage component 1, and the second airbag unit 22 includes at least one second airbag layer 221. The second airbag layer 221 includes multiple main airbags a1, multiple auxiliary airbags a2 and multiple connecting airbags a3. The multiple connecting airbags a3 are respectively connected to the main airbags a1 and the auxiliary airbags a2, and the connecting airbags a3 are connected to the adjacent auxiliary airbags a2 so that the second airbag layer 221 forms an arc-shaped surface after inflation, thereby covering and protecting the side edges of the pier 3. Preferably, the second airbag unit 22 is also stored in the cavity of the storage component 1.

[0027] Preferably, a first exhaust valve is respectively installed on the main airbag a1 and the auxiliary airbag a2 in at least one first airbag 211a, and a second exhaust valve is installed on the main airbag a1 and the connecting airbag a3 in at least one second airbag unit 22, so as to discharge the gas in the inflated main airbag a1, the auxiliary airbag a2 and the connecting airbag a3, and to facilitate placing the deflated and uninflated first airbag unit 21 and the second airbag unit 22 again inside the storage rack 11 for reuse.

[0028] In specific implementation, if the early warning system warns that a moving ship is about to collide with the bridge pier 3 and reaches a high risk of collision, the air source is turned on and air is simultaneously filled into the main airbag a1 and the auxiliary airbag a2 in the first airbag unit 21 and the second airbag unit 22. The auxiliary airbag a2 completes the inflation process first and drives the main airbag a1 to form quickly, thereby accelerating the inflation process of the main airbag a1 and shortening the inflation time. While the air source supplies air, the storage cover 12 at the right end of the storage rack 11 is opened, and under the rightward push of the push member 13, the storage bag 14 together with the first airbag unit 21 and the second airbag unit 22 installed in the storage bag 14 are pushed out from the right end opening of the storage rack 11. After being pushed out, the first airbag unit 21 and the second airbag unit 22 further expand and form multi-layer protection, thereby absorbing and dissipating the impact force of the colliding ship on the bridge pier 3, and the bridge pier 3 is well protected.

[0029] The present invention provides a bridge anti-collision airbag interception device, which includes a storage component and an airbag anti-collision unit. The storage component is installed on the outer side wall of the bridge pier, and a cavity is formed inside the storage component. The airbag anti-collision unit includes a first airbag unit, and the first airbag unit is installed in the cavity of the storage component. The first airbag unit includes at least one first airbag layer, and the first airbag layer includes a plurality of first airbags that are interconnected. At least one first airbag in the first airbag layer is connected to an external air source. In the bridge anti-collision airbag interception device provided by the present invention, the uninflated first airbag unit is stored in the cavity of the storage component, so that the bridge anti-collision airbag interception device in the unactivated state can always ensure the clearance space between the bridge piers. When activated, the first airbag expands after being inflated and quickly forms a multi-layer phase. The connected airbag anti-collision surface absorbs and dissipates the impact force when the ship hits the bridge pier, plays a protective role on the bridge pier, and avoids serious harm caused by the breakage of the bridge pier; on the one hand, the storage component is convenient for storing and installing the uninflated first airbag unit and the second airbag unit; on the other hand, the rightward movement of the push piece can quickly push the first airbag unit and the second airbag unit to a wider outside world, which is convenient for the rapid deployment of the first airbag unit and the second airbag unit, and also convenient for direct contact with the colliding ship; after the auxiliary airbag is inflated, it drives the main airbag to deploy and form, which speeds up the inflation process of the main airbag; the first airbag unit and the second airbag unit are respectively installed on the side and side edges of the bridge pier, so that the entire pier is well protected and the protection area is large.
