Automatic powerless water-filling and water-drainage counterweight gate

Abstract

The invention discloses an automatic powerless water-filling and water-drainage counterweight gate which comprises a steel gate body with a hollow interlayer, wherein a plurality of longitudinal and transverse support beam plates are averagely arranged in the hollow interlayer of the steel gate body at intervals; the hollow interlayer arranged on the lower part of the steel gate body is partitioned into a plurality of sealing water tanks by the longitudinal and transverse support beam plates; a water inlet pipe communicated with the upstream of a river channel is arranged on a water-facing side close to the bottom of the sealing water tanks; a plate-inserted type water inflowing / resisting device is arranged at a water inlet of the water inlet pipe; a longitudinal water drainage pipe communicated with the downstream of the river channel is arranged on the bottom wall of the sealing water tank; a gland type water drainage device is arranged in the longitudinal water drainage pipe; and an air intake / exhaust pipe which extends from the upper part of the water back surface, penetrates out of the upper part of the water back surface and is communicated with the downstream of the river channel is arranged on the top wall of the sealing water tanks. The automatic powerless water filling and water drainage counterweight gate has the advantages of simpleness of structure, convenience in mounting and using, capability of greatly lightening the load of starting and closing the machines, low construction cost, simplification of operation difficulty, energy conservation and wide application prospect.

Description

technical field [0001] The invention relates to a gate for water conservancy and hydropower projects, in particular to a non-powered automatic filling and draining counterweight gate. Background technique [0002] Plane steel gates are often used in water conservancy and hydropower projects. During the closing process of the existing flat steel gates, due to the existence of frictional resistance and buoyancy force, the gates cannot be closed by their own weight, and the gates need to be added with a counterweight to close the gates. . The traditional way of adding weight is mostly to place cast iron blocks, concrete blocks or iron sand concrete blocks inside the gate structure. This design cannot remove the counterweight during the lifting process of the gate, and it needs to be lifted together with the counterweight, causing the opening and closing machinery to The capacity of the opening and closing machinery is greatly increased; the increase in the capacity of the open...

Problems solved by technology

[0002] Plane steel gates are often used in water conservancy and hydropower projects. During the closing process of the existing flat steel gates, due to the existence of frictional resistance and buoyancy force, the gates cannot be closed by their own weight, and the gates need to be added with a counterweight to close the gates.

The traditional way of adding weight is mostly to place cast iron blocks, concrete blocks or iron sand concrete blocks inside the gate structure. This design cannot remove the counterweight during the lifting process of the gate, and it needs to be lifted together with the counterweight, causing the opening and closing machinery to The capacity of the opening and closing machinery is greatly increased; the increase in the capacity of the opening and closing machinery leads to an increase in the requirements for the opening and closing mechanical load, the installation process is more complicated, and the installation is more difficult
