Abstract

The life saving chair system for ship consists of signal system, control system and life saving chair. The life saving chair with floater has its lower part fixed to deck via sucking device, and the sucking device has inner cavity communicated with the pipeline below it. The control system includes controller and controller controlled valve set on the pipeline. Normally, the chair is fixed; and when the ship is to overturn, the signal system sends signal, the controller controls the valve to open to start the chair via making air enter the inner cavity, and the chair is made to separate from the deck and float for the passenger to escape.

Description

Boats and ships buoyant deck chair system

Technical field

The present invention relates to boats and ships, particularly the life saving system on the boats and ships.

Background technology

At present, boats and ships are met high wind or situation such as are hit a submerged reef and when toppling prominent, can cause very big personal casualty, its major cause comprise following some: 1, the whole process time of Ship's Capsize is of short duration, as shown in Figure 9, when boats and ships toppled meeting with billow, the whole process of Ship's Capsize had only 6 short seconds, and the passenger can not grasp life jacket or buoy quoit escape conveniently; 2, after the Ship's Capsize, article on the boats and ships, can be on the water surface floating very little, persons falling in water can't in time obtain buoying device.

Summary of the invention

Technical matters to be solved by this invention is: a kind of boats and ships buoyant deck chair system is provided.

The present invention solves the problems of the technologies described above the technical scheme that is adopted:

Boats and ships buoyant deck chair system is made up of signal generating system, control system and buoyant deck chair, and buoyant deck chair is the chair with floating debris, and the lower end of chair is fixing above deck by suction device; The suction device below is provided with pipeline, and an end of pipeline is communicated with the suction device inner chamber; Control system comprises controller and valve, and the unlatching of valve is controlled by controller, and valve is arranged on the pipeline; Controller is controlled by signal generating system.

In the such scheme, chair is provided with connecting rod, captives joint with suction device in the lower end of connecting rod.

In the such scheme, suction device inhales bowl by lining bowl, rubber and sucker is formed; The top of lining bowl is connected with connecting rod, and the bottom of lining bowl is inhaled bowl with rubber and is connected; Rubber is inhaled the bottom and the sucker adhesive of bowl, and the space that rubber is inhaled between bowl and the sucker is the suction device inner chamber; Sucker is fixing above deck.

In the such scheme, suction device is made up of the piston of cylinder and cylinder; Cylinder is fixing above deck; The upper end of piston is connected with connecting rod; The space is the suction device inner chamber in the cylinder of the lower end of piston.

In the such scheme, the residing deck of at least one pin of chair is provided with spacing collar, and the pin of chair is inserted in the spacing collar.

In the such scheme, valve is an electromagnetic gas valve.

In the such scheme, signal generating system comprises one or more in switch of inclination, mechanical trigger switch, the hand switch.

In the such scheme, the other end of pipeline is communicated with the gas cylinder with atmospheric pressure, and the atmospheric pressure in the gas cylinder is kept by air compressor.

System of the present invention makes it to become buoyant deck chair on the boats and ships, be provided with floating debris on the immediate chair of passenger.When boats and ships normally navigated by water, the valve of control system was in closed condition, and the suction device inner chamber of the lower end of chair is in vacuum state, and chair is fixed above deck firmly; When boats and ships are about to topple, signal system sends signal, and the controller by-pass valve control is opened, and starts buoyant deck chair, at this moment, air admission suction device inner chamber, suction device is chair no longer fixedly, and chair separates with the deck, behind the Ship's Sinking, buoyant deck chair can swim on the water surface, and the passenger can obtain floating debris conveniently, to help escape.

Usefulness of the present invention also is:

1, simple in structure, cost is low;

2, the residing deck of at least one pin of chair is provided with spacing collar, and it is spacing that spacing collar carries out level to chair, makes chair fix more firmly above deck;

3, signal generating system adopts degree of tilt sensing switch, mechanical trigger switch, hand switch, can guarantee the reliability of total system;

4, an end of pipeline is equipped with the gas cylinder with atmospheric pressure, and when valve opening, gas can promptly pour the suction device inner chamber, makes chair and deck break away from fast.

The specific embodiment

The embodiment of system of the present invention as shown in Figure 1, 2, it is made up of signal generating system, control system and buoyant deck chair, buoyant deck chair is the chair 1 with floating debris 2, the below of chair 1 is provided with a connecting rod 4, captive joint with suction device in the lower end of connecting rod 4, the lower end of chair 1 is fixed on the deck 3 by suction device; The suction device below is provided with pipeline 7, and an end of pipeline 7 is communicated with the suction device inner chamber; Control system comprises controller and valve, and valve is arranged on the pipeline 7.The unlatching of valve is controlled by controller, and valve is an electromagnetic gas valve, and controller is used for controlling the electromagnetic gas valve power supply.Controller is controlled by signal generating system.

When making valve opening, chair and deck can break away from fast, and pipeline 7 other ends can be communicated with the gas cylinder with atmospheric pressure, and the gas cylinder atmospheric pressure is kept by air compressor.

Shown in Fig. 2,3,4, the floating debris 2 on the chair 1 is a foam block, and the foam block Pasting is under seat.Chair 1 is captiveed joint with suction device by connecting rod 4.Suction device inhales bowl 6 by lining bowl 5, rubber and sucker 16 is formed; The top of lining bowl 5 is connected with connecting rod 4, and the bottom of lining bowl 5 is inhaled bowl 6 with rubber and is connected; Rubber is inhaled the bottom and sucker 16 adhesives of bowl 6, and the space that rubber is inhaled between bowl 6 and the sucker 16 is the suction device inner chamber; Sucker 16 is fixed on the deck 3.The residing deck 3 of a pin of chair 1 is provided with spacing collar 8, and the pin of chair 1 is inserted in the spacing collar 8.

As shown in Figure 5, suction device also can be made up of the piston 9 of cylinder 10 and cylinder 10; Cylinder 10 is fixed on the deck 3; The upper end of piston 9 is connected with connecting rod 4; The space is the suction device inner chamber in the cylinder 10 of the lower end of piston 9.
