Technical Field

The utility model relates to the field of weirs, in particular to a medium gate dam surface flow energy dissipation practical weir structure.

Background

The gate dam is formed by leading water without a dam developed by water diversion irrigation engineering to leading water with a dam, a low-rolling dam (weir) is built on a permeable foundation riverbed, the weir body of a medium-sized gate plate is particularly important as the basis of a sluice system, and the gate pier and the gate body are required to be arranged on the surface of the weir body.

Disclosure of Invention

The utility model aims to solve the defects in the background technology, and provides a medium gate dam surface flow energy dissipation practical weir structure.

In order to achieve the above purpose, the utility model adopts the following technical scheme: the utility model provides a medium-sized gate dam face flows practical weir structure of energy dissipation, includes the weir body, the fixed extension piece that is provided with in preceding lower limit of weir body, the upper surface of extension piece is provided with the sunk surface, the transition face has been seted up to preceding upper limit of weir body, the upper surface activity cartridge of transition face has a plurality of to slowly flow the piece.

Preferably, the weir body and the extension block are integrally formed, and the concave surface is a curved surface.

Preferably, the rear surface of the weir body is provided with a slope surface.

Preferably, a weir platform is arranged on the upper surface of the weir body.

Preferably, the upper surface of the transition surface is provided with a plurality of sockets, and the lower end of the slow flow block is inserted into the inner side of the socket in a sliding manner.

Preferably, the rear of the slow flow block is provided with a curved surface.

Compared with the prior art, the utility model has the following beneficial effects:

when the gate is opened, water flows fall into the concave surface through the transition surface, and the water is accumulated in the concave surface to play a role in buffering, and the extending block is of a hard structure, so that the impact of the water flows is less in damage to the extending block under the action of the matched buffering, and the water flows are prevented from directly impacting the river bottom based on the protection of the extending block, so that the stability of the weir structure is ensured; when the water flow passes through the slow flow block, the water flow after the diversion is diverted and the water from the direct flow are recombined, so that part of kinetic energy in the water flow can be effectively consumed, the kinetic energy of the water flowing down is reduced, so that damage to the position of the bottom of the river channel is reduced, and the whole structure is stable.

Detailed Description

The following description is presented to enable one of ordinary skill in the art to make and use the utility model. The preferred embodiments in the following description are by way of example only and other obvious variations will occur to those skilled in the art.

1-5, a medium-sized gate dam face flows energy dissipation practical weir structure, including the weir body 1, slope face 2 has been seted up to the rear surface of weir body 1, increase the stability of weir body 1, for the common design mode in the weir structure, the fixed extension piece 4 that is provided with in preceding lower limit of weir body 1, the upper surface of extension piece 4 is provided with concave surface 5, transition face 6 has been seted up on preceding upper edge of weir body 1, the upper surface activity cartridge of transition face 6 has a plurality of slow flow piece 8, a plurality of socket 7 has been seted up to the upper surface of transition face 6, the lower extreme slip of slow flow piece 8 inserts the inboard of socket 7, the slow flow piece 8 only need take up afterwards and can change.

The weir body 1 and the extension block 4 are integrally formed, and the concave surface 5 is a curved surface, so that the strength of the structure is ensured.

The upper surface of the weir body 1 is provided with a weir platform 3, and a gate pier and a sluice structure are arranged on the weir platform 3.

The back of the slow flow block 8 is provided with a curved surface, so that water flow can be uniformly split towards two sides.

When the valve is opened, as shown in fig. 4, water flows fall through the transition surface 6 and fall into the concave surface 5, water accumulation exists in the concave surface 5 to play a role in buffering, and the impact of the water flows is less in damage to the extension block 4 under the action of matched buffering because the extension block 4 is of a hard structure, and the water flows are prevented from directly impacting the river bottom based on the protection of the extension block 4, so that the stability of the weir structure is ensured; as shown in fig. 5, when the water flow passes through the slow flow block 8, the split water flow is split, and the split water flow and the water flowing from the direct flow are converged again (near the dotted line circling position in fig. 5), so that part of the kinetic energy in the water flow can be effectively consumed internally, the kinetic energy when the water flows down is reduced, the damage to the bottom position of the river channel is reduced, and the whole structure is stable.

The foregoing has shown and described the basic principles, principal features and advantages of the utility model. It will be understood by those skilled in the art that the present utility model is not limited to the embodiments described above, and that the above embodiments and descriptions are merely illustrative of the principles of the present utility model, and various changes and modifications may be made therein without departing from the spirit and scope of the utility model, which is defined by the appended claims.
