Ascending and descending type height-adjustable overflow plate structure

Abstract

The invention discloses an ascending and descending type height-adjustable overflow plate structure, which comprises a fixed water blocking plate fixedly arranged on a pool body, wherein the two ends of the fixed water blocking plate are respectively provided with longitudinal chute structures, and ascending and descending plates are arranged in the chute structures and are matched with the fixed water blocking plate and the chute structures in a sealed way. The chute structure is arranged on the fixed water blocking plate, the ascending and descending plate capable of upwards and downwards moving along the chute structures is adopted, through the proper structural design, the ascending and descending plate can still maintain the sealing state with the fixed water blocking plate and the chute structures after the height change, through the structure, the height of an overflow plate can be regulated in a certain range, and the water outlet water level of water discharge facilities such as flow cut-off wells can be regulated to different heights; the structure can realize a reverse check effect, when the overflow lower water level of the overflow plate is higher than the upper water level, the check effect can be realized through raising the height of the ascending and descending plate; the sealing performance of the structure is good, the structure is simple, and the manufacturability is good.

Description

technical field [0001] The invention relates to drainage system equipment, in particular to a lift-type height-adjustable overflow plate structure. Background technique [0002] In the drainage pipe network, in order to increase the outlet water level, water blocking devices are usually installed in the flow direction of interception wells and other facilities. The overflow plate is one of them. The front side of the overflow plate can intercept water at a certain level. When the water level is high When the height of the overflow plate is exceeded, the water flow overflows the overflow plate and flows to the other side of the overflow plate. The overflow plate needs to be sealed and cooperated with the interception well and other facilities to effectively intercept the water flow. Therefore, in order to ensure the sealing, the overflow plate generally adopts a fixed structure, such as a fixed overflow weir or gate in the interception well. The overflow height of the struct...

Problems solved by technology

The overflow plate needs to be sealed and cooperated with the interception well and other facilities to effectively intercept the water flow. Therefore, in order to ensure the sealing, the overflow plate generally adopts a fixed structure, such as a fixed overflow weir or gate in the interception well. The overflow height of the structural overflow plate is fixed and cannot be adjusted, so that its ability to adjust the water level is extremely limited
