Description

storage and drainage system

technical field

The utility model relates to a storage and drainage pipe system, which belongs to the technical field of drainage systems.

Background technique

With the frequent increase of urban waterlogging, there are more and more requirements for urban drainage systems. The original drainage system has a short return period, small pipe diameter, and low drainage capacity, which can easily cause water accumulation on the road and affect driving. Safety and daily travel, the current urban drainage system can no longer meet the requirements. In addition, because the rainwater contains a large amount of high-concentration suspended matter brought about by road scouring, these suspended matter will be deposited in the rainwater pipe, causing the rainwater pipe to silt, and thus become the main culprit for the reduction of the drainage capacity of the rainwater pipe.

For newly-built areas that have requirements for water storage and drainage, due to the high building density, the conditions for the construction of storage tanks are insufficient. In addition, the storage tanks will also have many problems such as easy siltation and maintenance of submersible sewage pumps; for sponge city construction demonstration areas, it may be difficult There is a "sponge body" with limited storage capacity. Under these circumstances, it is urgent to find an effective way to improve the drainage capacity of the newly built area, replace the traditional storage tank for decentralized water storage, and combine intelligent control to achieve intelligent drainage.

Utility model content

The purpose of the invention of the utility model is to provide a storage and drainage pipe system, which has a strong drainage and waterlogging prevention ability, replaces the traditional storage tank, and realizes intelligent drainage.

In order to achieve the purpose of the above invention, the storage and drainage pipe system of the present utility model includes an upstream pipeline, a downstream pipeline, and a detection well. The upstream pipeline and the downstream pipeline are respectively connected to both sides of the inspection well. There is a bottom-opening gate in the inspection shaft, and a slot is provided at the bottom of the inspection shaft. The hoist is connected to the bottom-opening gate through a lifting screw. The bottom-opening gate matches the slot, and the center line of the bottom-opening gate On the same straight line as the center line of the card slot, an ultrasonic liquid level gauge is provided on the upstream pipeline, and the ultrasonic liquid level gauge and the hoist are respectively connected to the controller.

The storage and drainage pipe system also includes a limiting device through which the lifting screw is connected to the side wall of the detection well.

A sealing ring is provided at the connection between the bottom opening gate and the upper end of the slot.

The use of this storage and drainage pipe system has the following advantages:

1. It can improve the drainage and waterlogging prevention capacity of the newly built area and ensure the safety of drainage.

2. Since the ultrasonic liquid level gauge and the hoist are respectively connected to the controller, the opening and closing of the down-opening gate can be intelligently controlled according to the liquid level in the upstream pipeline, and the volume of the upstream pipeline can be used as a rainwater storage tank. Control the regulation and storage of rainwater through the opening and closing of the bottom-opening gate, improve the drainage efficiency of the newly built area, and realize smart drainage.

3. Control the opening and closing of the bottom-opening gate through the controller, and use the upstream pipeline to regulate and store rainwater to realize the cleaning of the downstream pipeline.

detailed description

The storage and drainage pipe system shown in Figures 1, 2, and 3 includes an upstream pipeline 1, a downstream pipeline 2, and a detection well 3. The upstream pipeline 1 and the downstream pipeline 2 are connected to both sides of the inspection well 3 respectively. Shutdown 4, controller 10, the inspection shaft 3 is provided with a bottom-opening gate 7, the bottom of the inspection shaft 3 is provided with a card slot 8, the hoist 4 is connected with the bottom-opening gate 7 through a lifting screw 6, and the bottom The open gate 7 is matched with the card slot 8, and the center line of the bottom open gate 7 is on the same line as the center line of the card slot 8. The upstream pipeline 1 is provided with an ultrasonic liquid level gauge 9, and the ultrasonic liquid level gauge 9 , hoists 4 are connected with the controller 10 respectively.

The storage and drainage pipe system also includes a limiting device 5 through which the lifting screw 6 is connected to the side wall of the detection well 3 .

A sealing ring is provided at the connection between the bottom opening gate 7 and the upper end of the card slot 8 .

When the rainfall begins, the down-opening gate 7 is opened to the set height. At this time, the upstream pipeline 1 is mainly used for drainage. When the rainfall gradually increases and the ultrasonic liquid level gauge 9 detects that the water level reaches the set height, the ultrasonic liquid level The meter 9 transmits the signal to the controller 10, and the controller 10 controls the hoist 4 to drive the lifting screw 6 to descend until the bottom-opening gate 7 descends into the slot 8 and is fully opened. At this time, the upstream pipeline 1 is mainly used for drainage. When the rainfall decreases, the water level of the upstream pipeline 1 decreases, and the ultrasonic liquid level gauge 9 transmits the signal to the controller 10, and the controller 10 controls the hoist 4 to drive the lifting screw 6 to rise until the bottom opening gate 7 rises to the set height At this time, the upstream pipeline 1 is mainly used for water storage, storing a part of relatively clean rainwater. After the rainfall is over, the controller 10 controls the hoist 4 to drive the lifting screw 6 to descend, and the bottom opening gate 7 is opened. At this time, the upstream pipeline 1 The accumulated rainwater can flush the downstream pipeline 2, and the flushing rainwater enters the municipal sewage pipeline.

The hydraulic condition of the upstream pipeline 1 is the same as that of the downstream pipeline 2, and the pipe material, pipe diameter, and pipeline connection can be selected according to specific working conditions. The pipe diameter of the upstream pipeline 1 is determined according to the volume and value of drainage capacity and storage capacity. The bottom opening gate 7, the hoist 4, and the ultrasonic liquid level gauge 9 can be selected on the market according to specific working conditions and operating conditions. A sealing ring is arranged at the connection between the bottom opening gate 7 and the upper end of the draw-in groove 8 to ensure sealing. Simultaneously, the space inside the bottom-opening gate 7 and the draw-in groove 8 is tightly closed to prevent impurities in the rainwater from clogging up the internal space.

Multi-section inspection wells 3 can be set in the storage and drainage pipe system, and the inspection wells 3 can be designed according to the specifications of conventional inspection wells.
