Description

A kind of fire fighting truck is control and warning device automatically

Technical field

The utility model belongs to the fire-fighting equipment technical field, is specifically related to a kind of fire fighting truck control and warning device automatically.

Background technology

The fire-fighting system of present homemade main force fire fighting vehicle still rests on manual observation, manually operated primitive stage.There is the problem of following several respects in this fire fighting truck inevitably owing to the cause of performance configuration difference:

(1) require very high to fire fighter's skilled operation degree: eliminating that will be promptly and accurately when simple fault occurring, psychological quality to the fire fighter requires also very high, fire-extinguishing location is acted hurriedly in a messy situation and also will be accomplished to face the danger calmly, without any confusion, yet, the People's Armed Police of China is the obligation system, the fire fighter do several years just skillfully just retired, usually be that new hand is in operation, even there is the part technical backbone to stay with volunteer's identity, still have very big difference by comparison but add regular training in rotation system with the external occupation system that generally adopts, the gap of professional qualities is huge;

(2) resemble the bad key position that touches among the plant vehicle bodies such as PTO, water pump drive spindle, because proximity is poor, the bad timely discovery of fault comes off as oil starvation, heating, balance piece for propeller shaft etc., often suffer to destroy and know that just this moment, loss was irretrievable to related components;

(3) maloperation and self break down and cause fire fighting truck to be out of action is a loss to vehicle itself not only, affects the consequence that the fire extinguishing opportunity of combat brings thus adversely and can't estimate especially;

Therefore, under the prerequisite that China's system of military service can't change, how to simplify the operation sequence of fire fighting truck, improve the automatization level of fire fighting truck, thereby improving serviceability, rate on duty, the bulk life time of fire fighting truck, is the problem that fire fighting truck manufacturing enterprise need solve.

Eighties of last century the seventies, domestic just have producer to develop what is called " ten is automatic " fire fighting truck.Because our national electronic industry just had been in the starting stage at that time, civilian and industrial electrical equipment, electronic component quality all do not pass a test, and fault is frequent; And fire fighter's major part is from the rural area, mostly is chinesization just, and simple fault all is difficult to get rid of voluntarily, influences normally on dutyly, and leaveing no choice but the messenger of producer solution can not.This is all unacceptable concerning producing, use both sides, and " ten is automatic " comes out and just made no public appearances soon, and fire fighting truck has been got back to original state hand-manipulated again.

Along with electronic technology, vehicle with the development of various sensing components and parts and popularizing of computer, operation sequence is implemented control automatically and the key position working condition is implemented monitoring and handle automatically new opportunity is provided for fire fighting truck adopts micro computer.

Because the continuous variation of building, industrial materials, the difficulty of putting out a fire to save life and property of modern fire has had very big difference more decades ago, performance requirement to fire fighting truck has had large increase, the chassis that adopt fire fighting truck the developed area is to medium-to-high grade inclination, even the more superior external famous chassis of import performance.The user also wishes and can operate as " fool " camera, improves the performance that goes up dress synchronously.

Therefore need development to be suitable for automatic control, automatic alarm system that fire-fighting vehicle uses.

The content of utility model

Problem to be solved in the utility model provides a kind of fire fighting truck control and warning device automatically, this device can carry out manual adjustment and automatically control, the unexpected of fireman's personal safety that jeopardize that may occur in time got rid of the fire fighting truck job state of putting out a fire, simultaneously key position being monitored also in real time and taked the precautionary measures automatically according to setting in advance parameter, is the system of core with the sensor with micro computer, various difference in functionalitys, the electric operator that reduces damage of components.

A kind of fire fighting truck is control and warning device automatically, comprise water pump, water pot, engine and be installed in control unit of engine on the described engine, it is characterized in that: also comprise microcomputerized control box and the cooling-water temperature sensor, speed probe, oil pressure sensor, temperature sensor, pressure sensor and the liquid level sensor that are connected respectively with described microcomputerized control box.

Described water pump water outlet pipeline is provided with three forks, and a fork is provided with release bypass magnetic valve, is respectively equipped with outlet valve and big gun valve on two forks in addition, is connected with fire monitor behind the described big gun valve.

The utlity model has following advantage:

This fire fighting truck automatically control and warning device can carry out manual adjustment and control automatically, the unexpected of fireman's personal safety that jeopardize that may occur in time got rid of the fire fighting truck job state of putting out a fire, simultaneously key position being monitored also in real time and taked the precautionary measures automatically according to setting in advance parameter, is the system of core with the sensor with micro computer, various difference in functionalitys, the electric operator that reduces damage of components.

Description of drawings

Fig. 1 is a principle schematic of the present utility model.

The specific embodiment

The utility model will be further described below in conjunction with accompanying drawing.

Fig. 1 is a principle schematic of the present utility model, the utility model is realized by following several parts: (1) is controlled automatically to engine speed: gather tach signal by the speed probe 8 that is installed on chassis PTO or water pump transmission system a part, the output fill order is controlled the dynamoelectric accelerograph or the control unit of engine 7 on chassis after micro computer is handled, when engine changes in load, automatically adjust the size of throttle, engine speed is maintained near the allowed band of desired value;

(2) fire-fighting pump work pressure is controlled: gather the water pump water outlet pressure signal by the pressure sensor 1 that is installed on water pump water outlet pipeline appropriate location, the output fill order is controlled the dynamoelectric accelerograph or the control unit of engine 7 on chassis after micro computer is handled, make water pump system because external interference or fire extinguishing operation change, as increase and decrease hydraulic giant, cause discharge pressure to increase or when reducing, automatically adjust the size of throttle, water pump water outlet pressure is maintained near the certain limit of adjusted value automatically;
