Abstract
The utility model relates to a power station water discharge control system, which comprises a plurality of water pumps for discharging out water from a power station water pool, wherein a water level sensor is arranged in the water pool, the water level sensor transmits sensing signals to a PLC (programmable logic controller), each water pump is connected with the PLC through a soft starter, and the PLC starts the corresponding soft starter according to the sensing signals. The power station water discharge control system adopts the PLC, the water pump is started in real time according to the water level of the water pool and the state of a liquid level switch, the water leakage of the power station is handled in real time, or the accumulated water during the overhaul is discharged in real time, the water accumulation and the dampness inside a plant building are avoided, the normal operation and overhaul of equipment in a hydropower station is ensured, the unattended operation and the automatic control function are realized, and the work load of personnel is reduced.
Description
Technical field
The utility model relates to the drainage system in power station.
Background technique
In power generation process was formally put in the water power plant into operation, the power station had and leaks, production draining and domestic sewage, and these leak and tend to cause the inner humidity of plant and equipment and inner ponding, caused service life of equipment to shorten and equipment is in operation and is difficult to safeguard.Existing seepage drainage is all to carry out manually draining, is difficult to reach timely draining, causes the power station environment to stink to high heaven and equipment easily breaks down under wet environment.Simultaneously,, the ponding in spiral case, draft tube and pressure steel must be got rid of when overhauling unit when the water power plant.Existing drainage for overhaul adopts manual mode to control, and is difficult to ponding is got rid of totally, makes unit maintenance slow, and efficient is low, directly affects the manufacturing efficiency in power station.
The model utility content
For above-mentioned technical problem, the utility model provides a kind of drainage system of the automatic control of the timely eliminating of ponding when realizing timely processing that the power station leaks and maintenance.
The technical scheme in the invention for solving the above technical problem is: the power station drainage control system, comprise several water pumps from the outside draining in pond, power station, be provided with level sensor in described pond, this level sensor is passed to the PLC controller with induced signal, each described water pump is connected with described PLC controller by a soft initiator, and this PLC controller starts corresponding described soft initiator according to induced signal.
Further, the liquid-level switch sensor is installed in described pond, this sensor and described PLC control connection, this PLC controller is connected with a touch screen display.
Further, flow transmitter, pressure transmitter and mortor operated valve are installed on the drain opening of described water pump, described flow transmitter and pressure transmitter are passed to described PLC controller with signal, and PLC controls the aperture according to the described mortor operated valve of Signal Regulation.
As can be known from the above technical solutions, the utility model adopts the PLC controller, it is according to water level and the liquid-level switch state in pond, start in real time water pump, process in time that the power station leaks or the ponding when getting rid of maintenance, avoid the inner ponding of factory building and humidity, guarantee normal operation and the maintenance of equipment for hydroelectric station, realized unmanned, automatic control function, less personnel's work.
Description of drawings
Fig. 1 is structured flowchart of the present utility model.
Embodiment
Below in conjunction with Fig. 1, the utility model is described in further detail:
This power station drainage control system comprises several water pumps 2 of the 1 outside draining from the pond, power station, is provided with level sensor 3 in described pond, and this level sensor is passed to PLC controller 4 with the water level signal of induction; Simultaneously, each described water pump is connected with described PLC controller by a soft initiator 5, and this PLC controller starts corresponding described soft initiator according to the water level induced signal.Over predefined value, the PLC controller starts soft initiator makes pump working, and water is discharged rapidly when water level; When water level arrives normal value, close starter water pump is quit work, thereby realize unmanned, automatic control function, reduce a staff.
As preferably, liquid-level switch sensor 6 is installed in described pond, can detect the power station and whether exist and leak, this liquid-level switch sensor and described PLC control connection, but described liquid-level switch sensor level sensor is used in conjunction with, and makes native system more perfect, uses more extensive; Simultaneously, described PLC controller is connected with a touch screen display 7, when staff's maintenance maybe need be carried out seepage drainage, at first can input normal water place value scope on touch screen display, makes the PLC controller that predefined value is set.
Above-mentioned mode of execution is only for illustration of the utility model, and be not to be to restriction of the present utility model, the those of ordinary skill in relevant technologies field, in the situation that do not break away from the utility model spirit and scope, can also make various variations and modification, so all technological schemes that are equal to also should belong to category of the present utility model.
