In order to realize automatic control, the main difference between the embodiment 2 and the above embodiment 1 is that the intercepting well provided by this embodiment further includes a controller, the controller is respectively connected to the flow regulating power part 201 and the weir gate power part 301, and the controller is used for controlling the flow regulating power part 201 and the weir gate power part 301, for example, controlling the extension/contraction of the flow regulating power part 201, so as to achieve the purpose of adjusting the intercepting amount of the intercepting port and keeping the intercepting amount of the intercepting port constant when the water level in the water containing cavity 101 changes; the extension/contraction of the weir gate power part 301 is controlled to achieve the purpose of adjusting the height of the weir gate 304, and the automatic control function is facilitated.
In this embodiment, the controller may be a single chip, an ARM chip, a PLC, or the like. In order to realize automatic control, in a further scheme, the intercepting well further comprises a first monitoring device 401 for monitoring the liquid level height in the water containing cavity 101, as shown in fig. 7, the first monitoring device 401 is connected to the controller, the controller obtains the liquid level height data in the water containing cavity 101 through the first monitoring device 401, and adjusts the intercepting amount of the intercepting port according to the liquid level height data, so that not only can the automatic adjusting function of the intercepting amount of the intercepting port be realized, but also the intercepting amount of the intercepting port can be always kept constant when the water level in the water containing cavity 101 changes (when the water in an upstream pipe network changes frequently, which causes the water level in the water containing cavity 101 to change continuously), so as to avoid the flow fluctuation of a downstream pipe network, and facilitate the stable operation of the downstream pipe network and a sewage plant.
As shown in fig. 7, in order to realize the automatic backflow prevention function, in a further aspect, the catch basin further includes a second monitoring device 402 for monitoring a liquid level height downstream of the overflow weir gate device 300, the second monitoring device 402 is connected to the controller, the controller obtains liquid level height data downstream of the overflow weir gate device 300 through the second monitoring device 402, and adjusts an overflow height of the overflow weir gate device 300 according to the liquid level height data, so that the overflow height of the overflow weir gate device 300 is greater than the liquid level height data; by comparing the liquid level height of the upstream of the overflow weir gate device 300 (i.e. the liquid level height in the structure well 100) with the liquid level height of the downstream of the overflow weir gate device 300, the overflow height can be effectively adjusted, so that the water of the upstream of the overflow weir gate device 300 can smoothly overflow to the downstream, and the overflow height can be adjusted by monitoring the liquid level height of the downstream of the overflow weir gate device 300 in real time, and according to the liquid level height, thereby effectively preventing the natural water from flowing backwards.
Preferably, the first monitoring device 401 and/or the second monitoring device 402 may be a liquid level sensor, a liquid level meter, a liquid level switch, or the like, so as to monitor the liquid level.
The above description is only for the specific embodiments of the present invention, but the protection scope of the present invention is not limited thereto, and any person skilled in the art can easily think of the changes or substitutions within the technical scope of the present invention, and all should be covered within the protection scope of the present invention.
