Abstract
The utility model discloses a multifunctional automatic monitoring device for an oil house which can monitor and control the loading and unloading of oil level and accidental leakage of the oil house. In the device, the oil level of a distant oil house is denoted in a linear way on a mercury column pressure meter by an air pressure sensor, and the monitoring and controlling of the oil level, loading and unloading and accidental leakage of the oil house are realized by using the electrical conductivity of mercury and the positive and negative interlocking of various relays.
Description
Multi-functional oil depot automated watch-keeping facility is applicable to the monitoring and the control of oil level, loading and unloading and the leakage of all kinds of large-scale oil depots and oil sector.
At present, most of oil depot of China is all used cursory monitoring oil level, cursory placing on the oil depot because oil depot is far apart from pumping plant, so this original monitoring method only is applicable to the routine observation oil level, and can't monitoring leakage, also can not monitor loading and unloading.So a large amount of accidental release phenomenons often takes place in the oil storage of oil depot and cargo handling process, brings about great losses to country.
Some large-scale oil depots adopts electronic scales monitoring, and this monitoring device can directly be measured the reserves of oil depot, but it can only measure and be located on the high mountain or the oil tank reserves of tens of rice on overhead, and then puts into other jars, and precision is between 3～5 ‰.The outfit of this monitoring device needs 200,000 yuan, can not monitor the leakage of oil depot.
The monitoring of the oil level in the utility model oil-collecting storehouse, the monitoring three big functions of the monitoring of loading and unloading and control and leakage be in one, and have characteristic of simple structure.
Multi-functional oil depot automatic monitoring device principle of work as shown in the figure.
One, the monitoring of oil level: the bottom that a gas sensor (parts 2) is placed oil depot (parts 1), by gas sensor the oil pressure of oil depot bottom is converted to air pressure, by the conduit (parts 3) that communicates with sensor air pressure is delivered to mercury box (parts 4) again.With the mercury box mercury column type tensimeter (parts 5) that links.Like this, manometric mercury solution face can be along with the rising (or decline) of the oil level of oil depot rise linearly (or decline).This mercury column type tensimeter is placed in the observation ward.Just can make the observer in observation ward from the manometric scale the Direct observation oil level.For ease of operation and the observation of pump man in the remote pump house, the equidistant hard contact that some is installed on mercury column meets each the signal lamp (d on extension line and the remote pump house control desk again
1, d
2D
n) link.Different height of mercury is passed to corresponding signal lamp to electric current by each hard contact and extension line, makes it shinny.The pump man can understand according to the demonstration of signal lamp whether pump oil is to specifying oil depot and understanding its oil level in pump house like this.Thereby realized in observation ward and pump house, observing simultaneously the function of oil level.
Two, the automatic control during the oil depot charge of oil: with full oily signal lamp (d
n) auxiliary reclay (JZ in parallel
1) and alarm (B
2).The anti-interlocking of relay is located in the electromagnetic coil circuit of three-phase electromagnetic contactor.And this contactor is connected in the oil pump circuit.When oil is filled to full oil level and puts, JZ
1I.e. energising is closed, JZ
1Anti-interlocking disconnect.Just termination of pumping immediately of oil pump (D), alarm generation sound equipment represents that this oil depot is full simultaneously.Between twice pump, can cut off the oil pump power supply.When connecting charge of oil, after one jar of full oily termination of pumping, can not cut off the electricity supply, oil pipeline is led to another oil depot, and a whole set of oil level signal on line is received on the extension line of mercurypressure table of corresponding oil depot (method of attachment can be socket connect can be additive method) yet.In case connect, oil pump can open pump automatically.
Automatic monitoring when three, unloading tank wagon: on the Oil pump electrical machinery main circuit, adorn a current transformer (L), on mutual inductor, meet AC intermediate relay (JZ again
2) and an adjustable resistance (R).With JZ
2just interlock and seal in the electromagnetic coil circuit of three-phase electromagnetic contactor.Induction current during the Oil pump electrical machinery operate as normal makes it be equivalent to JZ through the adjustment of R
2The value of keeping.When unloading tank wagon and unstow, air just can enter fuel sucking pipe, and the load of Oil pump electrical machinery is reduced, thereby the electric current of motor main circuit is descended, and the induction current of current transformer also decreases.JZ like this
2Electric current in the circuit (being induction current) is lower than the value of keeping, and makes JZ
2just interlock and disconnect the circuit cut off the three-phase electromagnetic contactor, oil pump quits work.While JZ
2Anti-interlocking connect the signal lamp (D that links with it
2) shinny, the expression oil sources is empty, and the termination of pumping when being different from full oil.Can't start oil pump (the three-phase electromagnetic contactor is in off-state) this moment once more.For opening pump once more, establish a direct current auxiliary reclay (JZ again
3), with JZ
2And JZ
3The parallel connection of just interlocking.Press the button A before the startup earlier
2, artificially connect JZ
3Power supply, make J
Z3Just interlocking connect.Thereby connect electromagnetic contactor circuit (C).Press start button A again
1Because huge electric motor starting electric current makes J
Z2Just interlocking closed once more, can cut off A this moment
2, make host circuit 2 at J
Z2Guaranteed.
Thereby oil depot charge of oil and the automatic monitoring of unloading tank wagon have been realized.
Four, the automatic monitoring of Guo Louing: automatically alarm circuit is by alarming line, relay (J
Z4), alarm (B
1) and signal lamp (D
1) form.Many hard contacts are arranged on mercury column, connect alarming line by oil level when needing.Electric current is through power supply like this, mercury column, and hard contact, alarming line is to relay J automatically
Z4, J
Z4Just interlocking and connecting signal lamp (D1), the bright expression of lamp does not have leakage phenomenon to take place, and the explanation warning device is in running order.When occurring leaking,, cut off J owing to the decline of mercury column along with oil level descends
Z4Power supply, J
Z4Anti-interlocking closure connected alarm circuit, alarm sends sound equipment, leakage phenomenon has taken place in expression.During artificial emptying, need unload the alarm circuit (A10) of oil tank, in case unexpected warning.
The utility model does not adopt the complex apparatus of high, precision and frontier technology, and is simple in structure, and the monitoring error is in 2 ‰.
