Description

High-speed jet flow security device for ship

Technical Field

The utility model relates to a marine security technical field especially relates to a marine high-speed efflux security device.

Background

In the operation of the ship, the condition that personnel outside the ship intrude into the ship is sometimes encountered, so that the safe operation of the ship and the safety of the crew and goods are damaged.

In order to prevent personnel outside the ship from illegally entering the ship, various security facilities are arranged on the ship. For example, the inclined ladder channel cover plate is a security design.

The deck face at the current inclined ladder department of boats and ships deck of this design sets up a apron, and the apron is located the rigidity of perpendicular deck face at ordinary times. The bottom of the cover plate is provided with a hinge, and the top of the cover plate is provided with a lock catch. When security demand, crewman operation apron rotates 90 degrees along the hinge, and the apron flushes with the deck face, closes the current passageway of inclined ladder to with the hasp with the apron lock on the deck face, prevent that invasion boats and ships personnel pass through the inclined ladder, enter into deck and the room on upper strata more.

The security cover plate has a good function of preventing intruders from passing. But has the disadvantage of long operation time, and the crew needs to put down the cover plate and lock the cover plate by using the lock catch. In addition, the cover plate is easy to be damaged by tools for intruders. The intrusion prevention mode is single.

Detailed Description

The following description of the preferred embodiments of the present invention will be given with reference to the accompanying drawings, fig. 1 and 2, and will make the functions and features of the present invention better understood.

Referring to fig. 1 and 2, a high-speed jet security device for a ship according to an embodiment of the present invention includes a plurality of nozzles 1, a security fluid delivery pipeline 2, a plurality of security fluid supply assemblies 3, a flow switch 4, and a stop valve 5; the security fluid supply assembly 3 is connected with each nozzle 1 through a security fluid conveying pipeline 2; the flow switch 4 and the stop valve 5 are arranged on the security fluid conveying pipeline 2; the nozzles 1 are provided on the left and right sides and the front side of the top opening of at least one staircase 6 of a ship.

The shut-off valve 5 is provided with a locking device. The stop valve 5 is normally closed and locked by a locking device, and a key of the locking device is kept by a crew member on the ship in charge of security protection.

A warning board is arranged near the stop valve 5 to remind of unauthorized operation of the stop valve 5, and the stop valve 5 needs to be opened by a crew in charge of security.

The flow switch 4 is connected with an alarm device in communication. For realizing the alarm function. When the nozzle 1 is sprayed with the security fluid, the flow switch 4 triggers an alarm signal to remind a crew of paying attention to the dangerous area.

The security fluid supply assembly 3 is used for conveying security fluid to the security fluid conveying pipeline 2; the security fluid comprises steam, high-pressure compressed air, high-pressure fire water and tear gas. The security fluid can be steam, high-pressure compressed air, high-pressure fire water and other media which are conveniently available on the ship; or any other fluid medium such as tear gas; regardless of the fluid medium, the type of fluid medium requires international regulations to permit use, strictly prohibiting the use of fluids that the international regulations expressly cannot use.

The amount of the security fluid is determined according to the desired intrusion prevention time.

The nozzle 1 comprises a spray head 11, and the spray head 11 is fixed through a threaded seat plate 12 and communicated with the security fluid conveying pipeline 2.

The security fluid connected to the security fluid conveying pipeline 2 may be one type, or a plurality of branch pipes may be connected to a plurality of types of security fluids. But at the same time only one security fluid is used.

When discovering the invasion of extra-ship personnel, the security crew opens stop valve 5, and nozzle 1 spouts the security fluid, prevents that the invading personnel from passing through this ladder way and entering the deck of one side more. The flow switch 4 triggers an alarm signal to remind a crew member that the nozzle 1 is in a working state.
