Description

A rapid dredging device for water conservancy projects

technical field

The utility model relates to a rapid dredging device for a water conservancy project, which relates to a device for dredging a river bed during water conservancy construction, and belongs to the field of water conservancy construction. In particular, it relates to a dredging device which utilizes the impact of pumping out river water and cooperates with the rotation of the rotating block to disperse mud and dirt so that it can be sucked away and stored.

Background technique

At present, in water conservancy construction operations, it is often necessary to carry out dredging operations on the riverbed to remove silt so that water resources can be transported smoothly. The traditional riverbed dredging method is to divide the river into several sections and carry out dredging separately. It is necessary to build a cofferdam in the river first, pump out the water in the cofferdam, and use manual excavation or excavator excavation to carry out dredging operations. The construction period of this dredging method is long and the consumption of manpower and material resources is large. Now When the commonly used water conservancy dredging equipment is used for dredging, the negative pressure generated by the pumping equipment will pump away the residual water and mud at the bottom of the river bed together. The power generated when the water flows is effectively used, and the cleaning efficiency is low and the effect is not good.

Contents of the invention

In order to improve the above situation, a quick desilting device for water conservancy projects of the utility model provides a desilting device that utilizes the impact of pumping out river water and cooperates with the rotation of the rotating block to break up the mud and dirt so that it can be stored away. It can effectively improve the efficiency of dredging the river bed.

A quick dredging device for a water conservancy project of the utility model is realized in the following way: a quick dredging device for a water conservancy project of the utility model is composed of a main body device and a dredging device, and the main body device is composed of a sewage suction pipe, a dirty storage tank, a fixed cover, It consists of a connecting rod, a protective cover and a diversion cover. The protective cover is placed at the bottom of the dirt storage tank, and the diversion cover is placed on the protective cover. The mouth of the diversion cover is trumpet-shaped, and a through hole is opened on the diversion cover. There is a through hole on one side of the dirt storage tank, and it is close to the bottom of the dirt storage tank. On the diversion cover, and corresponding to the through hole on the diversion cover, the top of the dirt storage tank has a through hole, the fixed cover is placed on the top of the dirt storage tank, one end of the connecting rod is placed on the fixed cover, and the dredging device It is composed of water pump, filter screen, guide pipe, fixed ring, driving motor, water spray pipe, rotating rod, connecting block, rotating block and spiral blade. The driving motor is placed in the protective cover, and the motor shaft of the driving motor passes through The bottom of the protective cover is placed in the diversion cover, the rotating rod is placed in the diversion cover, and one end is connected to the motor shaft of the driving motor, the spiral blade is placed on the rotating rod, and the rotating block is placed on the other end of the rotating rod through the connecting block , the cross-section of the rotating block is triangular, the filter screen is placed on the inner wall of the top of the sewage storage tank, the water pump is placed in the fixed cover, the water inlet pipe on the water pump is connected with the through hole at the top of the sewage storage tank, and one end of the diversion tube is connected to the through hole at the top of the sewage storage tank. The water outlet pipes on the water pump are connected and communicated with each other. The water spray pipe is placed on the other end of the flow guide pipe and communicated with the flow guide pipe. The water spray pipe corresponds to the rotating block. The ring is connected to the other side of the dirt storage tank.

When in use, when dredging the river bed, first connect the connecting rod to the external fixing device, then put the diversion cover into the river bottom, the river water carries the silt into the diversion cover, and the drive motor and the water pump work at the same time. The driving motor drives the rotating rod to rotate, and the rotating rod drives the screw blade to rotate, and drives the rotating block to rotate through the connecting block. During the rotating process, the screw blade drives the water and silt in the shroud to flow upward, and then makes the water and silt enter the suction After the river water is filtered by the filter, it is pumped into the diversion pipe by the water pump, and the sludge is stored in the sewage storage tank. The river water in the diversion pipe flows into the water spray pipe, and then sprayed from the water spray pipe out, to impact the sludge at the bottom of the river, and cooperate with the rotation of the rotating block to disperse the harder sludge, which is easy to be sucked away by the sewage suction pipe. In the diversion cover, it can achieve the purpose of dredging the river bed during water conservancy construction.

Beneficial effect.

1. The structure is simple, convenient and practical.

Second, the price is low and easy to promote.

3. It can effectively improve the efficiency of dredging the river bed.

Description of drawings
