Description
Technical field
The utility model relates to underground heat technical field, particularly relates to a kind of groundwater level monitoring device of underground heat.
Background technology
In recent years, along with the fast development of society, what energy problem and environmental problem became is be becoming tight day, and as everyone knows, underground heat is more and more subject to liking of people as a kind of novel clear energy sources, and underground heat is a kind of heat resource from earth interior.Earth interior is a huge heat reservoir, the such as lava temperatures as high 1200 DEG C ~ 1300 DEG C of volcano ejection, the temperature of natural hot spring mostly more than 60 DEG C, have even up to 100 DEG C ~ 140 DEG C, these heats from earth interior can be converted into the energy.When this heat oozes out earth's surface, geothermal energy resources are just become.
Therefore, underground heat is drawn from underground to utilize by people be a significantly thing, at present, thermal power plant unit in community is general all at basement, and basement water table ratio is lower at ordinary times, because underground water is easy to metal run out, and then invade bubble to unit, its result causes unit easily impaired.So the groundwater level monitoring device designing and developing a kind of underground heat seems particularly important.
Utility model content
The technical problems to be solved in the utility model is: the groundwater level monitoring device providing a kind of underground heat.
The technical scheme that the utility model is taked for the technical matters existed in solution known technology is:
A groundwater level monitoring device for underground heat, comprising:
For detecting the first water level switch of underground water table lower limit;
For detecting the second water level switch of the underground water table upper limit;
SIEMENS PLC-200 Programmable Logic Controller;
For realizing the protocol converter of data remote transmission;
And terminal control unit; Wherein:
The analog input terminal of described SIEMENS PLC-200 Programmable Logic Controller is electrically connected with the first water level switch and the second water level switch respectively; The digital quantity I/O terminal of described SIEMENS PLC-200 Programmable Logic Controller is connected with terminal control unit by protocol converter; Described terminal control unit is connected with alarm; The lead-out terminal of described SIEMENS PLC-200 Programmable Logic Controller is electrically connected with the first dredge pump, the second dredge pump and make-up pump.
As optimal technical scheme, the utility model additionally uses following technical scheme:
Described terminal control unit is the industrial computer with multiple display.
The advantage that the utility model has and good effect: by adopting technique scheme, when underground water table rises to the first water level switch or the second water level switch, the first water level switch or the second water level switch can trigger startup first dredge pump and/or the second dredge pump by SIEMENS PLC-200 Programmable Logic Controller; And then make underground water table recover range of normal value, meanwhile, staff also can grasp the scope of underground water table in time by terminal control unit, prevent trouble before it happens.
Accompanying drawing explanation
Fig. 1 is circuit block diagram of the present utility model.
Wherein: 1, terminal control unit; 2, protocol converter; 3, SIEMENS PLC-200 Programmable Logic Controller.
Embodiment
For utility model content of the present utility model, Characteristic can be understood further, hereby exemplify following examples, and coordinate accompanying drawing to be described in detail as follows:
Refer to Fig. 1, a kind of groundwater level monitoring device of underground heat, comprising:
For detecting the first water level switch of underground water table lower limit;
For detecting the second water level switch of the underground water table upper limit;
SIEMENS PLC-200 Programmable Logic Controller 3;
For realizing the protocol converter 2 of data remote transmission;
And terminal control unit 1; Wherein:
The analog input terminal of SIEMENS PLC-200 Programmable Logic Controller 3 is electrically connected with the first water level switch and the second water level switch respectively; The digital quantity I/O terminal of described SIEMENS PLC-200 Programmable Logic Controller 3 is connected with terminal control unit 1 by protocol converter 2; Terminal control unit 1 is connected with alarm; The lead-out terminal of SIEMENS PLC-200 Programmable Logic Controller 3 is electrically connected with the first dredge pump, the second dredge pump and make-up pump.
The principle of work of above-mentioned specific embodiment is: when underground water table rise to the first water level switch or/and the second water level switch time, first dredge pump is or/and underground water table is discharged by the second blowdown pump startup, simultaneously, staff also can grasp the scope of underground water table in time by terminal control unit 1, if underground water table is too high, staff also can close make-up pump by terminal control unit 1.Therefore, the utility model effectively can realize monitoring and the regulation and control work of underground water table.
As preferably, the terminal control unit 1 in above-mentioned specific embodiment is for having the industrial computer of multiple display.
In order to realize the continuous adjustment to current in hot water pipeline, in this specific embodiment, solenoid valve is proportion magnetic valve.
Above embodiment of the present utility model has been described in detail, but described content being only preferred embodiment of the present utility model, can not being considered to for limiting practical range of the present utility model.All equalizations done according to the utility model application range change and improve, and all should still belong within patent covering scope of the present utility model.
