Technical field
The invention belongs to safety interlocking technical field, particularly a kind of solar energy safety interlock.
Background technique
Using one of maximum facility at numerous areas such as petrochemical industry, rock gas, food, harbours is pipe-line system, is used for long-range fed sheet of a media.In process of construction, usually can be dirty, leave over foreign material; In use, there will be fouling, absorption, precipitation, obstruction, the transfer efficiency of pipeline is reduced, affect the precision of quality of product, influence process instrument etc.At this moment just relate to pipe-line purging work, and pipeline service work; Therefore need to pipe cleaning emitting cylinder and receiving barrel be installed at the first and last end of pipeline, in order to facilitate pigging or service work, conventionally can use fast-open blind plate.We know in pipeline and conventionally have pressure, for safety operation, on adagio, a set of interlocking mechanism can be installed, and prevailing interlocking mechanism is mechanical, does not pull down interlocking mechanism, and blind plate cannot be opened.Need to discharge the pressure in pipeline before release and confirm that pressure reduces to atmospheric pressure state, the most generally judge that the method for pressure height is pressure gauge indicating value or the pressure transmitter of installing on cylindrical shell by watching.But the situations such as indicating value is inaccurate, precision, sensitivity attenuating, damage that pressure gauge or pressure transmitter there will be, at this moment, operator there will be erroneous judgement, illusion, open blind plate and there will be security incident, therefore need a kind of pressure measurement interlock reliably, to guarantee the Security of blind plate operation.
Conventional security interlock is made up of the head of interlocking, trigger switch, explosion-proof electrical distribution box, internal logic circuit, warning light, externally fed pattern.Basic functional principle: interlocking head is arranged on blind plate, inner pressurized chamber communicates with pipeline, the backward outer side shifting of piston pressurized of sealing, triggering has pressure signaling switch, internal circuit receives switching signal and drives warning light flicker, representing has pressure in pipeline, otherwise after manifold pressure discharges, piston is mobile reset to the inside under the effect of Returnning spring, release-push, internal circuit has lost and has compressed switch after signal, remove state of alarm, warning light extinguishes, represent that manifold pressure has discharged, can operate blind plate opens, but it is explosion-proof that traditional safety interlock detecting switch needs, volume is large, install and use inconvenience, explosion-proof tank volume is large, floor space is large, and cost is high, is inconvenient to move, control circuit mostly is discrete component, poor reliability, the mechanical relay, the power consumption of traditional alert lamp that use are high, remote power feeding causes engineering cost significantly to increase.
Summary of the invention
The deficiency existing for prior art, the invention provides the solar energy safety interlock that a kind of volume is little, be convenient to installation, maintenance, the high and low power of reliability, environmental protection and energy saving.
The technology used in the present invention solution is: a kind of solar energy safety interlock, comprise interlocking head, lock tube, piston, Returnning spring, piston rod and switch, described interlocking head is connected with lock tube, described piston is arranged in lock tube, described piston is connected with piston rod, on described piston rod, be provided with Returnning spring, one end of described piston rod is provided with permanent magnet, and described switch is magnetic switch.
A kind of control circuit for solar energy safety interlock, comprise photovoltaic cell, photovoltaic controller, singlechip controller, storage battery, magnetoelectric induction pressure measurement switch, red LED warning light and green LED warning light, the output terminal of described photovoltaic cell is connected with the input end of photovoltaic controller, the I/O of described storage battery is connected with the output of photovoltaic controller input, the I/O of described photovoltaic controller is connected with the input/output terminal of singlechip controller, described magnetoelectric induction switch, red LED warning light is connected with singlechip controller with green LED warning light.
Compared with prior art, the beneficial effect that the present invention has is: detecting switch of the present invention has adopted Magnetic Induction switch, is encapsulated in the metal tube of 12mm diameter, uses resin embedding; Not only volume little, be more convenient for install; Permanent magnet is embedded in piston rod end.Control circuit is used single-chip microcomputer instead as master control device, writes control program, makes that circuit height is integrated, volume is little, low power consumption, stable and reliable for performance; The part of reporting to the police is two colored high-brightness LED light sources, and red light lights flicker for there being pressure condition; Green light lights flicker for passive state, intuitively eye-catching, also accomplishes low power consumption.The solution of power supply is to use photovoltaic cell to gather solar energy, and can be stored in the 12V storage battery of configuration, while having sunlight, package unit energy consumption derives from photovoltaic generation, use the energy of battery stores overcast and rainy or night, not only energy-conservation but also environmental protection, has removed the trouble of remote power feeding completely, has reduced installation intensity, cost.
