Description

a dam gate

technical field

The utility model relates to the technical field of water conservancy equipment, in particular to a dam gate.

Background technique

A dam is a water retaining structure that intercepts the flow of a river channel to raise the water level or regulate the flow. It can form a reservoir, raise the water level, adjust the runoff, and concentrate the water head for flood control, water supply, irrigation, hydropower generation, and improved shipping. The river remediation buildings that adjust the river situation and protect the bank bed are also called dams, such as spur dams, dams, and submerged dams. By setting dam gates, the water flow is controlled. Closing the gates can block floods, block tides or raise the upstream water level. To meet the needs of irrigation, power generation, shipping, aquatic products, environmental protection, industrial and domestic water, etc.; open the gate, it can vent floods, waterlogging, abandoned water or waste water, and can also supply water to downstream rivers or channels. In water conservancy projects, sluice gates are widely used as structures for retaining, discharging or taking water.

In order to control the production cost of the existing dam gate, the structure is too simple, the connection between the gate and the embedded part is too simple, and the sealing performance is poor. The supporting force of the device and the embedded contact part, when the water flow is too large, the gate's own tensile stress cannot resist the strong force of the water flow, resulting in a greatly reduced service life of the device, unable to play a role in resisting floods, and will produce huge personnel. property loss.

The utility model is provided with grooves and convex grooves that match each other between the sealing device and the gate, and a sealing strip is arranged between the grooves and the convex grooves, so that the sealing performance of the gate is better, and the traditional gate is prevented from passing through and pre-conditioning. The structure of the shape and position contact between the buried bodies for water-tight sealing prevents the sealing performance of the gate from becoming worse due to the continuous wear of the edge of the gate due to long-term use, and the water flow continues to erode the edge of the gate, which shortens the service life of the device. By setting the groove of the sealing device to wrap the convex groove on the edge of the gate, the edge of the gate is effectively protected from contact with the water flow, preventing the gate from rusting and aging due to the continuous erosion of the water flow, making the gate difficult to lift and so on.

2. The utility model is driven by the hydraulic push rod by setting the sealing device. When the sealing device compresses the two ends of the gate, it provides a lateral support force for the gate, increases the overall stability and structural strength of the device, and enables the gate to withstand greater pressure. Longitudinal water flow pressure, while ensuring the water flow tightness of the gate, improves the pressure resistance of the gate, makes the device have better drainage and interception capacity, and improves the service life of the gate.
