The hydraulic flushing gate regulating pond gate flushing system can fully utilize the potential pipeline capacity to store wastewater; it utilizes the stored wastewater to flush the pipelines; and it offers flexible control over wastewater of varying water qualities based on the water quality conditions. The installation position of the retaining flushing gate is determined by the wall structure of the structure. The retaining gate can be locked with a pivot rotation.

Operation process as follows:
Divide the rainwater storage pond into multiple flushing channels. Then, in each channel, separate a single storage compartment for storing incoming water during the daily inflow into the storage pond, serving as the flushing water source for cleaning the pond. When water pollutants settle at the bottom of the pond and require cleaning, empty the rainwater storage pond, activate the hydraulic system via the PLC control system, open the flushing door before the storage compartment, and begin cleaning the channel.

Hydraulic Flush Door, Retaining Basin Gate Flush
The device utilizes the retention function of the retention gate to fully store wastewater in the pipeline's potential capacity; it uses the retained wastewater to flush the pipeline; and it flexibly controls wastewater of different qualities based on water quality conditions. The installation position of the retention flush gate is determined by the structural walls of the structure. The retention gate rotates around a pivot and can be locked at any position. When idle, the retention gate can be locked in a wide-open state; when retaining water, it is locked closed, sealing with the bottom of the pipeline to retain wastewater. The designed retention gate can be set for *outflow or bottom outflow. Retention pool flushing valve, retention shield flushing hydraulic flap gate

Made of stainless steel, the structure is sturdy and durable; one-time flush length 10

Primary Functions and Application Range:
Large Tri-Aldehyde Intermediate Wash】Primarily used for oil washing and maintenance of drainage pipelines with larger diameters, such as sewage or combined sewers, culverts, and rectangular ditches. Additionally, it can serve as a management facility for the entire pipeline network through the containment function of the barrier gates, utilizing the potential capacity of the pipelines. The hydraulic flushing gates are mainly installed in stormwater detention basins or culverts, providing automatic flushing for sediment at the bottom. They are characterized by long-lasting operation.

Technical Advantages
Excellent rinsing effect, with the effective rinsing length of a single rinsing wave exceeding 100 meters.
Technologically mature and refined, operationally reliable and stable, and has been verified through practical examples.
Made of stainless steel, the structure is sturdy and corrosion-resistant.
Water intake at the bottom of the storage room, even when the regulating pond is not at full capacity, the storage room can be automatically filled.
No noise, external power, external water source, energy-saving, environmental protection
Basic low maintenance

Rainwater harvesting ponds are typically fully underground structures with considerable depth. They operate for a limited number of days throughout the year, serving their storage purpose only during rainy periods. Therefore, the operation modes of newly constructed rainwater harvesting ponds are usually unattended or minimally staffed with scheduled inspections. China has developed relatively late in the technology of rainwater harvesting pond utilization. Early rainwater harvesting ponds mainly had the "storage" function, lacking "adjustment" and "utilization" features, and are in urgent need of upgrades or supplementation.
Rainwater storage ponds are typically connected to municipal stormwater wells for the collection and storage of rainwater; they are equipped with drainage pumps and level gauges. The drainage pumps are connected to the municipal stormwater pipes through drainage pipes, used to pump the stored rainwater into the municipal stormwater pipes during rainfall. The level gauges display the water level within the storage pond. Current technology relies on manual on-site operations for the storage, utilization, and management of rainwater storage ponds. Due to the widespread distribution of these ponds in urban construction, often built underground, and unclear responsibilities—although all part of the city's drainage system, some are under municipal jurisdiction, while others are under property management—it is both difficult and costly to manage them manually. On the other hand, since the storage function of rainwater storage ponds requires emptying before heavy rain, with the widespread and numerous locations of these ponds, it is challenging to monitor and empty them within a short time upon receiving heavy rain warnings. Relying on manual management is difficult to effectively control the ponds within a short time frame, leading to insufficient management and lack of timeliness. Moreover, on-site operation requires trained workers, increasing labor costs. If the storage ponds cannot be effectively emptied before heavy rain, it may increase the probability of urban flooding.
