Abstract
The utility model belongs to the technical field of the internal -combustion engine uses auxiliary assembly, concretely relates to diesel locomotive oil tank theftproof warning circuit system. The utility model discloses a can the early warning relevant staff, reduce internal -combustion engine and the stolen possibility of fuel, provide a diesel locomotive oil tank theftproof warning circuit system, including the relay of power, alarm and contact normal close formula, be equipped with automatic switch in total return circuit at power place, alarm and relay are parallelly connected, and the normally closed contact of relay locates the alarm place on the road, and relay place branch road is equipped with self reset push key switch. This circuit system can in time report to the police, and the notice reminds relevant personnel further to make the theftproof action, and fundamentally has controlled the oily rate of stealing, it is simple that it constitutes the component, and what just adopt is the diesel locomotive 110V battery in area certainly, and it is simple to connect the mounting means, can not change the diesel locomotive structure, and the practicality is strong.
Description
Technical field
The utility model belongs to combustion engine and uses technical field of auxiliary equipment, is specifically related to a kind of diesel locomotive Security for fuel tank alarm circuit system.
Background technology
In recent years along with international and domestic diesel-fuel price sustainable growth, the stolen event of IC engine fuel happens occasionally, and not only causes certain economic loss, also has a strong impact on locomotive and normally uses.Current anti-theft measure is generally improve cover structure for fuel tank or increase anti-theft column lock, but such anti-theft measure is mainly set about from theft complexity, can not play forewarning function, when there is theft situation, can not and alarm remind relevant staff.
Summary of the invention
The utility model in order to can early warning relevant staff, reduces combustion engine and the stolen possibility of fuel oil, provides a kind of diesel locomotive Security for fuel tank alarm circuit system.
The utility model adopts following technical scheme:
A kind of diesel locomotive Security for fuel tank alarm circuit system, comprise the relay of power supply, annunciator and contact normally closed, automatic switch is provided with in the total loop at power supply place, described annunciator and relay parallel connection, and the normally closed contact of relay is located on the branch road of annunciator place, relay place branch road is provided with self reset push key switch.
Described self reset push key switch is installed on below the fuel oil box lid of diesel locomotive.
Described power supply is the 110V storage battery that diesel locomotive carries.
The utility model has following beneficial effect:
1, when there is error state (when oil stealer opens fuel lid or cuts off somewhere circuit), this Circuits System energy and alarm, notifying and reminding related personnel to make antitheft action further, fundamentally controlling stolen rate;
2, the composition component of this Circuits System is simple, and employing is the 110V storage battery that diesel locomotive carries, and connection mode is simple, can not change diesel locomotive structure, practical.
Accompanying drawing explanation
Fig. 1 is circuit control principle figure of the present utility model;
In figure: 1-power supply, 2-annunciator, 3-relay, 4-automatic switch, 5-self reset push key switch, 6-normally closed contact, 7-fuel oil box lid.
Detailed description of the invention
By reference to the accompanying drawings, detailed description of the invention of the present utility model is described further:
Diesel locomotive Security for fuel tank alarm circuit system as shown in the figure, comprise the relay 3 of power supply 1, annunciator 2 and contact normally closed, automatic switch 4 is provided with in the total loop at power supply 1 place, described annunciator 2 and relay 3 parallel connection, and the normally closed contact 6 of relay 3 is located on the branch road of annunciator 2 place, relay place branch road is provided with self reset push key switch 5, below the fuel oil box lid 7 being installed on diesel locomotive.
The 110V storage battery that described power supply 1 carries for diesel locomotive, and not by storage battery plug-in strip and switch control rule, when ensure that diesel locomotive stops in locomotive shed, circuit still can normally work.
The principle of work of this Circuits System is:
1, during normal working: fuel lid is normally closed, self reset push key switch 5 closes, and relay 3 is obtained electric, then the normally closed contact 6 of relay 3 disconnects, annunciator power-off.
2, during abnormal operation: oil stealer opens fuel lid, self reset push key switch 5 disconnects, and makes relay 3 dead electricity, then the normally closed contact 6 of relay 3 closes, and annunciator obtains electric alarm.When oil stealer cuts off circuit any point under car, relay 3 dead electricity, then the normally closed contact 6 of relay 3 closes, and annunciator obtains electric alarm.
