Technical Field

The invention belongs to the field of hydraulic engineering construction, and particularly relates to a gravity-center-self-adjusting anti-wave dredging pipe.

Background

Dredging pipes are commonly used for cleaning and conveying silt, slurry and other mixed impurities in the construction process of most of hydraulic engineering, and are also commonly used for improving water environment, restoring ecology, constructing and burying various underwater pipeline ditches and the like in addition to the water conservancy construction process.

In hydraulic engineering, most of traditional dredging pipes often need to float on the water surface to convey mud, but when the surface of water is greatly stormy waves, a plurality of dredging pipes can collide with each other, so that the surface of the dredging pipes is easily damaged in the past, and the mud can be leaked seriously.

For this reason, we propose a storm-resistant dredging pipe with self-adjusting gravity center to solve the above problems.

Disclosure of Invention

The invention aims to solve the problem that most of the conventional dredging pipes are easy to collide with each other and damage, and provides a gravity-center-self-adjusting anti-wave dredging pipe which can effectively protect the dredging pipe.

In order to achieve the purpose, the invention adopts the following technical scheme: the utility model provides a pipe is dredged to unrestrained anti-wind of self-interacting focus, includes the body, the outside coaxial cover of body is equipped with the protecting tube, be equipped with a plurality of rolling balls between protecting tube and the body, the fixed block of two liang of relative settings of fixedly connected with multiunit on the lateral wall of body, every the fixed block all rotates and is connected with the dwang, every the other end of dwang all rotates through the coil spring and is connected with the kickboard, every group the equal fixedly connected with gasbag of lateral wall that the kickboard was carried on the back mutually, every group all be equipped with between the kickboard and float the box, two sliding connection has two sliding blocks in the floating box, two the equal fixedly connected with connecting rod of lateral wall that the sliding block was carried on the back mutually, two the other end of connecting rod all extends to the.

The invention has the beneficial effects that:

the dredging pipes are arranged at the upper end of the floating plate, so that collision among the dredging pipes when the wind waves are large can be avoided, the surface of the dredging pipes is damaged, and the dredging pipes can be effectively prevented from tilting under the action of the floating plate and the floating box.

In foretell unrestrained dredging pipe of anti-wind of self-interacting focus, the external diameter of connecting rod is less than the internal diameter that floats the box, can prevent effectively that the connecting rod from driving the sliding block and from floating the inside roll-off of box, can carry on spacingly to the sliding block.

In the wind and wave resistant dredging pipe with the gravity center self-adjusting function, each expansion ball is filled with evaporation liquid and a magnet ball, a magnetic block which is attracted with the opposite poles of the magnet balls is embedded in the side wall of the pipe body, and a friction layer is arranged on the inner side wall of each expansion ball.

The magnet ball can jump in the expansion ball under the action of the magnetic force of the magnetic block, so that heat is generated by friction with a friction layer, evaporated liquid absorbs the heat to be vaporized, the whole expansion ball expands, the sliding blocks are pushed to two ends, the floating plate drives the whole dredging pipe to move downwards, the gravity center of the dredging pipe moves downwards, the stability of the dredging pipe can be effectively improved, and the pipe is prevented from inclining.

In the anti-wave dredging pipe with the gravity center self-adjusting function, arc-shaped baffles are fixedly connected to the side walls of the floating plates in each group, and the arc-shaped baffles are arranged at the upper ends of the air bags.

When the floating amplitude of the floating plate with large wind waves is large, the air between the arc-shaped baffle plate and the air bag can provide buoyancy, so that the whole device is further prevented from tilting.
