Rubber fishing pontoon

Abstract

The invention provides a rubber fishing pontoon which comprises a cylindrical rubber pontoon body. Hemispheric rubber end sockets are integrally connected to the two ends of the rubber pontoon body. Flange cover boxes are connected to the outer sides of the ends of the rubber end sockets. Buffering cavities are formed in the flange cover boxes. Inflation one-way valves, stop valves and safety valves which all communicate with the corresponding buffering cavities are arranged on the end faces of the outer sides o the flange cover boxes. Air nozzles are integrally connected to the ends of the rubber end sockets. One end of each air nozzle communicates with the corresponding rubber pontoon body and the other end of each air nozzle communicates with the corresponding buffering cavity. The rubber fishing pontoon has the beneficial effects that the pontoon is made of rubber and is flexible, capable of achieving the vacuum state, easier to fold, small in occupied volume, low in weight, easy to transport and capable of achieving the functions such as inflation leakage prevention, automatic exhausting, emergency exhausting and valve set protection and guaranteeing the safety of the inner pressure of the pontoon body.

Description

technical field [0001] The invention relates to a rubber fishing buoy. Background technique [0002] The salvage buoy is a container that produces water buoyancy. It is sealed around and can generate huge buoyancy when immersed in water. It can provide controllable buoyancy for sunken seas and salvage of sunken objects. It is one of the important equipments for emergency rescue in case of incidents. It is used to salvage sunken ships and sunken objects. It can also be used to assist stranded and rocked ships to get out of the water, and maintain the buoyancy and stability of damaged ships. [0003] At present, there are generally two types of salvage buoys: metal buoys and rubber buoys. The buoyancy of metal buoys is large, there are several types of 500 tons, 400 tons, 200 tons, 80 tons, and 40 tons; the buoyancy of rubber buoys is small, such as 10 tons, 5 tons, etc. Metal buoys, with barrel, handguard, ladder, mooring hole, quick-sinking valve, inflation valve, submarin...

AI Technical Summary

Problems solved by technology

Due to the large size and heavy weight, the actual operation is inconvenient, the procedures used are complicated, the requirements for the control of the operation link are high, and its internal structure is complicated, which makes the manufacturing and maintenance costs high. Therefore, the use of metal buoys has many disadvantages, but in order to Realize engineering construction, have to spend expensive cost and human resources to carry out engineering application

[0005] For the buoyancy tonnage, inflation and deflation control, and fixed binding methods of the current rubber buoys, the technology is immature. There are only some small buoys without a unified standard configuration. Multiple buoys are required to be used together, which increases the actual difficulty of operation and also brings complexity to the inflation and deflation control. Moreover, there is currently no mature inflation and deflation and buoyancy control technology, and the bearing pressure of the cylinder is small. It is only suitable for shallow water salvage with a water depth of more than ten meters, and the practical application field is very small
