Abstract
An independent type overflow-prevention control system for a fueling vehicle comprises a power supply, at least one isolator, at least an overflow-prevention sensor and a liquid level control switch. The isolator is connected between the power supply and the overflow-prevention sensor, the overflow-prevention sensor is intrinsically safe explosion-proof type and protrudes into fuel tank of the fueling vehicle in the liquid level upper limit position, the signal output end of the overflow-prevention sensor is connected with the signal input end of the liquid level control switch, the liquid level control switch is arranged inside a control case on the body of the fueling vehicle and has the control signal output end thereof connected with an electromagnetic valve for controlling on/off of a fuel pump, and the electromagnetic valve is connected between the liquid level control switch and the fuel pump. The independent type overflow-prevention control system is installed on the fueling vehicle and can monitor liquid level through the overflow-prevention sensor. The system is a control device capable of independently controlling safe liquid level of fuel product, has nothing to do with an external fuel reservoir and the fuel pump of the fuel reservoir, and changes the situation that in the prior art, when fueling from the bottom of the fueling vehicle, the control system is only suitable for the fuel reservoir and the liquid level sensor can only control the fuel pump of the fuel reservoir.
Description
Technical field
The utility model relates to a kind of anti-overflow control system that is installed on the filling car.
Background technology
Two kinds of methods are arranged for the filling car charge of oil, a kind of is by manhole charge of oil from the top down, another kind is to be that oil tank carries out the bottom loading operation by the oil pump that is installed on the filling car bottom, and when the bottom loading operation, need to rely on the anti-overflow control system to guarantee that the oil product electrolyte level in the filling car is no more than perch.Existing anti-overflow control system only is fit to oil depot and uses, the anti-overflow control system can only be controlled oil product electrolyte level in the filling car by the last oil pump of control oil depot, and the oil pump on the uncontrollable filling car, when filling car during not at the oil depot charge of oil, just have no idea to utilize the oil product electrolyte level in the anti-overflow control system monitoring filling car, so be easy in the filling car refueling process, occur the oil spilling phenomenon.
The utility model content
The purpose of this utility model provides a kind of
Filling car is with free-standing anti-overflow control system, solve existing filling car
Do not existJust can't monitor the technical matters of oil product electrolyte level in the filling car during oil depot charge of oil.
For achieving the above object, the utility model adopts following technical scheme: a kind of filling car is with free-standing anti-overflow control system, it is characterized in that: by power supply, at least one isolator, at least one anti-overflow sensor and liquid level control switch are formed, be connected with isolator between described power supply and the anti-overflow sensor, described anti-overflow sensor is a liquid level upper limit position in intrinsic safe explosion-proof type and the oil tank that stretches into filling car, the signal output part of anti-overflow sensor links to each other with the signal input part of liquid level control switch, liquid level control switch is located in the control box of vehicle body of filling car, its control signal output ends is connected with the electromagnetic valve that the control oil pump opens and closes, and electromagnetic valve is connected between liquid level control switch and the oil pump.
Another control signal output ends of described liquid level control switch links to each other with indicator lamp.
Another control signal output ends of described liquid level control switch links to each other with voice guard.
Compared with prior art the utlity model has following characteristics and beneficial effect: the utility model is installed on the filling car, by anti-overflow sensor monitoring liquid level, it is a kind of control setup that can independently control oil product liquid level safe altitude, when when tank bottom is the oil tank charge of oil, can prevent that oil product from overflowing from the oil tank top.After having used the utility model, when the oil product electrolyte level in the filling car arrives the safe altitude at anti-overflow sensor place, will send sound and light alarm, remind the site operation personnel to note the oil product electrolyte level, and stop the fuel feeding of oil pump.
Principal feature of the present utility model is to carry out independent control to the oil pump on the filling car, irrelevant with the last oil pump of extraneous oil depot and oil depot, the anti-overflow control system can only be fit to the oil depot use when having changed in the past to the filling car bottom loading, and level sensor also can only be controlled the situation of the last oil pump of oil depot.After adopting the utility model, filling car both can oil depot with oil depot on oil pump refuel, the oil pump that also can be under environment arbitrarily carries on filling car carries out bottom and fills oily operation, and charge of oil can reach the requirement that anti-overflow is controlled in any environment.
Principle of work of the present utility model: adopt the piezoelectric type principle design, the anti-overflow sensor is installed at the oil tank top, the anti-overflow sensor is the intrinsic safe explosion-proof type, oil pump on the filling car drives by the power takeoff on the automobile, the work of power takeoff is by solenoid control, when the oil product liquid level that fills from tank bottom with after the anti-overflow sensor contacts, anti-overflow sensor passes signal is to liquid level control switch, liquid level control switch issues a signal on the electromagnetic valve again, stop by the solenoid control power takeoff, oil pump on the filling car is quit work, to reach the purpose that stops charge of oil.
Description of drawings
The utility model is described in more detail below in conjunction with accompanying drawing.
Fig. 1 is that the utility model is installed in the scheme drawing on the filling car.
Fig. 2 is a module diagram of the present utility model.
Reference numeral: 1-anti-overflow sensor, 2-oil pump, 3-liquid level control switch, 4-filling car, 5-control box.
The specific embodiment
Embodiment is referring to shown in Figure 1, this filling car is with free-standing anti-overflow control system, by power supply, at least one isolator, at least one anti-overflow sensor 1 and liquid level control switch 3 are formed, be connected with isolator between described power supply and the anti-overflow sensor 1, described anti-overflow sensor 1 is a liquid level upper limit position in intrinsic safe explosion-proof type and the oil tank that stretches into filling car, the signal output part of anti-overflow sensor links to each other with the signal input part of liquid level control switch 3, liquid level control switch 3 is located in the control box 5 of vehicle body of filling car, its control signal output ends is connected with the electromagnetic valve that control oil pump 2 opens and closes, and electromagnetic valve is connected between liquid level control switch and the oil pump.All have power takeoff and oil pump on the described filling car, wherein power takeoff drives oil pump work, and electromagnetic valve is controlled oil pump 2 keyings by the control power takeoff.
Another control signal output ends of described liquid level control switch 3 can link to each other with warning device, and warning device can be an indicator lamp, also can be voice guard, also can be that the both has, and what present embodiment adopted is indicator lamp.
