Detailed Description
It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
It should be noted that in the description of the present invention, the terms "lateral", "longitudinal", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc. indicate orientations or positional relationships based on those shown in the drawings, and are only for convenience of description and simplicity of description, and do not indicate or imply that the referred device or element must have a specific orientation, be constructed and operated in a specific orientation, and thus, should not be construed as limiting the present invention. Furthermore, the terms "first," "second," and the like are used for descriptive purposes only and are not to be construed as indicating or implying relative importance.
Referring to fig. 1 to 3, in the present preferred embodiment, a pier airbag housing apparatus includes a housing 8, an airbag cushion 1, an airbag, a gas generator, and an inflation control device, wherein,
the cover box 8 surrounds the pier outside and can float on the surface of water, installs crashproof air cushion 1 on the lateral wall of cover box 8 (facing the ship face promptly), installs the folding gasbag of placing and the gas generator who communicates with the gasbag on the inside wall of cover box 8 (facing the pier face promptly), and it is inside that inflation control device is located cover box 8, and gas generator passes through the gas tube and is connected in order to aerify it with the gasbag.
The airbag device includes an airbag and a gas generator. The jacket 8 may be of a construction commonly known in the art. The casing 8 is ensured to be exposed on the horizontal plane, and each controller cannot enter water, so that the normal monitoring and the control signal sending cannot be realized. Certain distance is guaranteed between the sleeve box 8 and the bridge pier, so that the airbag can be guaranteed to have enough space to open the airbag after the ignition gas reaction, otherwise, the airbag cannot be smoothly opened, and the airbag is crushed due to extrusion when being opened instantly, and the protection effect is lost.
In this embodiment, the jacket 8 is of a rectangular structure (may be arranged in a ring structure, as long as it is enclosed around the outer side of the bridge pier), the top wall of the jacket 8 is provided with the folded airbag, and the top wall of the jacket 8 is also provided with the gas generator.
Specifically, the inflation control device comprises a collision monitoring sensor 6, a central controller 10 and an air bag reaction controller (comprising a top air bag inflation control device 4 and an adjacent bridge pier surface inflation control device 11) which are electrically connected in sequence, the air bag reaction controller is electrically connected with an ignition device of the gas generator, and the air bag is connected with the gas generator through an inflation tube.
Specifically, a plurality of (a plurality of indicate three or more) airbags are installed on the inside wall of the jacket 8, each airbag is matched with an airbag reaction controller and a gas generator, namely, each airbag is independently controlled, and the airbag on the corresponding side is opened when a certain side collides, so that unnecessary waste is reduced.
Preferably, the four top walls of the suitcase 8 are each fitted with a folded-down airbag (i.e. the top airbag 2). The four inner side walls of the sleeve box 8 are all provided with folded air bags (namely the air bags 3 facing the bridge pier surface).
The anti-collision air cushion 1 is detachably mounted on the sleeve box 8 through the air cushion mounting device 9, so that the anti-collision air cushion 1 is convenient to replace, and the sleeve box 8 does not need to be replaced. The air bag is in a cuboid strip-shaped structure after being inflated. When no impact occurs, the air bag is made into a contracted cuboid structure. The inflation control device and the air bag are separately arranged, and the air bag is difficult to reuse after being used once because the inflation control device is a device capable of being recycled, so that the air bag is convenient to replace to save cost.
The distance between the inner side wall of the preferable sleeve box 8 and the outer side wall of the pier is 1-3 m. The method is specifically set according to the actual co-traveling conditions of different piers, the tonnage of a protected anti-collision ship and whether the pier is a main channel pier or not. And the two sides of the sleeve box, which are not adjacent to the ship, can be designed to be narrower than the ship facing side, so that the distance of a main channel for navigation is ensured to be wider, and the side edges are not easy to impact.
The top wall of the tank 8 is kept above the water level after it is placed in the water.
The working principle of the pier anti-collision air bag sleeve device is as follows. When the monitoring sensor 6 receives a signal that a ship is about to collide with a pier, data are transmitted to the central controller 10, the top airbag inflation control device 4 and the pier face inflation control device 11 are controlled, the sleeve airbag anti-collision device in the shape of the figure 2 is formed in the moment, the top airbag inflation control device 4 and the pier face inflation control device 11 send ignition signals, a large amount of gas is rapidly generated after the gas generator is triggered to ignite to expand airbags, the sleeve airbag anti-collision device is clamped between the ship and the pier 13, the kinetic energy of a ship body is absorbed in a large amount, an effective buffering energy absorption effect is generated, and therefore the pier is protected.
The bridge pier anti-collision air bag sleeve device provided by the embodiment has the following beneficial effects:
(1) the sleeve box 8 is rigid, so that a certain resisting capability is increased, but the sleeve box 8 can float on the water surface and is not very heavy, so that devices such as an inductor and a central controller 10 in the sleeve box 8 can be supported above the water surface, and the phenomenon that the normal work cannot be performed due to water inflow is avoided;
(2) because the installation project of the sleeve box 8 is large, the air bag can be detachably arranged, the inflation control device is fixed on the sleeve box 8, and a lead is used for connecting the gas generator, so that the sleeve box 8 can be conveniently replaced after use, and the sleeve box 8 can be repeatedly utilized; moreover, after the collision prevention air bag sleeve box device for the bridge pier is impacted by a ship, the air bag is opened, and only the air bag needs to be replaced instead of the sleeve box 8 after the air bag is damaged, so that the operation and maintenance cost can be reduced;
(3) because the height of the sleeve box 8 is far lower than that of some ships with low draft, the top of the sleeve box is provided with the air bag, so that the anti-collision device can be changed into a super large protective cover to protect the bridge piers;
(4) the suit case 8 faces the ship face and installs crashproof air cushion 1, fails to expand completely because of various reasons when the gasbag, can not effectually protect the pier, if do not have crashproof air cushion 1, boats and ships and suit case 8 are direct rigid collision, and the energy-absorbing effect to boats and ships is not good while just the pier has obtained the protection also can cause not little loss to boats and ships itself.
The above description is only for the preferred embodiment of the present invention and is not intended to limit the scope of the present invention, and all equivalent structural changes made by using the contents of the present specification and the drawings, or any other related technical fields, are intended to be covered by the scope of the present invention.
