Abstract

PROBLEM TO BE SOLVED: To provide a float bag system that causes a heavy load to float by installing a float bag in the water with a small number of persons and inflating it in the water, since the heavy load such as an automobile entering and sinking in the river or sea cannot pull it out by the human power.SOLUTION: The bag 1 in which the air is not entered is brought into the water and installed by the side of the heavy load such as a sinking automobile 11 etc. and they are made to float on the water surface by sending compressed air from a compressor provided in a vehicle 9 of the wharf or a shipboard to the float bag 1 in the water, and inflating the float bag in the water. There is provided the float bag that includes a mechanism to perform decompression of the seawater and increasing the air pressure in the float bag, and emits the air in the water by an exhaust valve, and that might not explode.

Description

The present invention provides a device that can lift a heavy object such as an automobile that has been accidentally dropped from a pier or bridge from the bottom of the water with a small number of people, and is effective in fields such as lifesaving, maintenance of the bottom of the water, and cleaning up. To do.

Recently, cars that enter the water from the bridge over the pier or river are often reported. It takes half a day to a day or two to ask for a crane to lift a sunken car. I think that it will not be possible to help people in the car, and if the passenger car has a compressor and a floating bag, connect the compressor and the floating bag and bring the floating bag without air into the water. I found a tool that lifts heavy objects such as automobiles by placing a floating bag on the underbody of the car underwater, sending compressed air from the surface of the car to the water, and inflating it in the water. So devise and provide.

Patent application 2003-200176

If heavy objects such as automobiles enter the pier or river, even if an emergency police car comes, it cannot be lifted, and it can be lifted until a crane car or crane ship arrives. If a simple instrument that can easily lift a car that has entered the police car of an emergency car is suitable, if a small number of rescuers can be lifted up to the surface of the water so that it is left in the car etc., rescue I couldn't find it, though I searched for various instruments. Therefore, a system using a floating bag as a main tool is provided.

A floating bag body (1) and a system are provided as a tool for lifting a heavy object such as a vehicle sinking to the bottom of the water by sending compressed air to the water on land or water.

If a vehicle equipped with a levitating bag system set comes from the pier or riverbank with a heavy object such as a car that has fallen underwater, a person who has mastered swimming the levitating system set to the bottom of the water without waiting for a crane or crane ship Installed underwater on heavy objects such as a car or a ship that has gone and sunk, and by sending compressed air from the compressor from above the water, the floating bag in the water expands and floats while automatically expelling the air that expands while floating Therefore, with a relatively small number of people, you can lift the floating bag from the bottom of the water to the water with air without rupturing it.

A floating bag body (1) that is deflated from the atmosphere is carried by a person holding the floating bag body (1) to a vehicle that sinks to the bottom with the compressor (9) connected to the compressor (9), and is sinking to the bottom. Open the floating bag body (1) on the side of the vehicle, etc., and install the hook (8) on the body of the sinking vehicle (11). A vehicle (11) or the like that is sunk by sending air to the floating bag body (1) from the intake valve (3) of the floating bag body (1) set at the bottom of the water with a compressed air supply hose (10) and inflating in the water. To lift the air while exhausting with the automatic exhaust valve (4) so that the floating bag main body (1) does not rupture with the automatic exhaust valve (4) placed under the floating bag main body (1). Is.

The structure of the side of the levitation bag is that the levitation bag body (1) is made of a light and strong material such as tent fabric or sail fabric, and is used as a weight so that the position of the bag can be oriented downward. A heavy weight reinforcement member (5) having a supporting role is attached, and a weight reinforcement band (2) for supporting an object with a bag is provided in a band shape so as to cover the bag body. Passing through the mounting hole (6), the weighting measure mounting hole (6) is provided with the weighting measure (7), and the weighting bracket (8) is provided below the weighting measure (7).

The intake valve (3) is located at a position where the intake valve of the bicycle or automobile is sucked up below the rear surface of the intake valve. An automatic exhaust valve attached to a commercially available diving dry suit is provided at the lower part of the front and rear surfaces to automatically discharge the air that expands as it rises due to the difference between water pressure and air pressure.

Recently, news such as accidents in which heavy objects such as automobiles fall into the water from wharves and bridges have been taken up in the news one after another.
If you look at the news, there are cases where people are on board, and activities such as rescue activities are performed, and you can see the scenes being lifted with a crane. Since the crane is called, it seems that it will take more than half a day at least, it seems impossible to save if there is a person, it is time to get a police vehicle as an emergency car at least I thought that there was a life to be saved if it was able to surface on the surface.
Therefore, if there is a device that can be loaded and installed by a small number of people under the surface of a water vehicle, such as a police car, it can be installed by a small number of people. It is intended to devise and provide a buoyancy bag that can be used to levitate. It can be used for rescue and can lift and remove sediments that hinder the navigation of ships.
In addition, it can be used for fisheries if it can be removed by towing by sending compressed air from the fishing boat to lift fishing reefs, sunken nets, sunken boats, etc. in the event of a tsunami.
