[0023] The opening and closing and overflowing mechanism includes a hand-crank and electric dual-purpose opening and closing gate 1, the hand-crank and electric dual-purpose opening and closing gate 1 is installed at the input end of the outlet pipe 8, an overflow pipe 5 for overflowing and discharging water is installed on the side wall of the precast wellbore 7, and the height of the overflow pipe 5 is greater than the heights of the inlet pipe 4 and the outlet pipe 8.
[0024] The precast wellbore 7 is rectangular, and the well depth, overflow height and pipe diameter are adjusted according to site requirements. The hand-crank and electric dual-purpose opening and closing gate 1 is an attached wall gate made of ordinary stainless steel and is subjected to double-sided pressure.
[0025] During use, the flow of the outlet pipe 8 is controlled by opening and closing the hand - electric dual - purpose opening and closing gate 1. When the hand - electric dual - purpose opening and closing gate 1 is closed, the water level inside the precast wellbore 7 will rise. After the water level reaches the overflow pipe 5, it will be discharged through the overflow pipe 5.
[0026] The monitoring mechanism includes an ultrasonic level gauge 2 for collecting water level information. The ultrasonic level gauge 2 is installed at the top of the precast wellbore 7 near the maintenance opening 6. A conductivity meter 3 is installed at the top of the precast wellbore 7. The probe of the conductivity meter 3 hangs naturally. A lightweight material is installed on the side wall of the probe of the conductivity meter 3 to facilitate the probe to float with the water level for monitoring. A DN50 perforated pipe for blocking garbage is sleeved on the conductivity meter 3, and the DN50 perforated pipe is vertically installed on the inner wall of the precast wellbore 7.

A photovoltaic panel 11 is installed at the upper end of the side wall of the electric pole 9. The photovoltaic panel 11 is used in combination with the commercial power to ensure the normal operation of the control well. A control box 10 for receiving the data information of the ultrasonic level gauge 2 and the conductivity meter 3 and controlling the hand - electric dual - purpose opening and closing gate 1 is installed on the side wall of the electric pole 9.

[0031] This device is powered by two ways, namely the photovoltaic panel 11 and the external commercial power. Under normal circumstances, the power supply is provided by the photovoltaic energy storage battery. When there are extremely continuous cloudy days and the energy storage battery cannot guarantee the normal power consumption demand of the system, the system automatically switches to the commercial power supply, ensuring the normal operation of the system while using clean energy.
[0032] The working principle of an intelligent control well:
[0033] The control system inside the control box 10 collects the real-time data of the ultrasonic level gauge 2, the conductivity meter 3, and the rain gauge 12, and sends DO commands according to the control strategy pre-programmed by the program to realize the opening and closing of the hand-operated and electric-operated gate 1, and feedback the status signal. The hand-operated and electric-operated gate 1 can implement a three-level control mode, namely local manual control, local automatic control, and remote hand / automatic control.
[0034] Specifically: In daily use, the hand-operated and electric-operated gate 1 is in the normally open state. When the rain gauge 12 acts to indicate the rain state, the ultrasonic level gauge 2 detects that the water level in the precast wellbore 7 rises, and at the same time, the conductivity signal of the conductivity meter 3 keeps decreasing. When it reaches the set value or below, the control box 10 controls the hand-operated and electric-operated gate 1 to close.
[0035] After the hand-operated and electric-operated gate 1 is closed, the water level in front of the hand-operated and electric-operated gate 1 is higher than the water level behind the hand-operated and electric-operated gate 1, and the conductivity signal of the conductivity meter 3 keeps increasing. When it reaches the set value or above, the control box 10 controls the hand-operated and electric-operated gate 1 to open, completing a complete control operation.
[0036] For those skilled in the art, it is obvious that the present utility model is not limited to the details of the above exemplary embodiments, and can be implemented in other specific forms without departing from the spirit or basic characteristics of the present utility model.
