Detailed description of the invention
Fig. 1 is hydraulic brake system accident warning device structural schematic diagram.
Specific embodiment
Hydraulic brake system embodiment
The present embodiment provides a kind of hydraulic brake systems, and further, which is common hydraulic disk
Brake system, certainly, the invention is not limited to hydraulic disc brake systems.
Hydraulic brake system further includes for solution feed pump operating status in detection system other than including braking mechanism
Fault detection module and a kind of accident warning device, since braking mechanism belongs to brake system inherent structure, any brake system
There is braking mechanism, therefore, be just no longer described in detail here to braking mechanism in system.
The effect of fault detection module be detect solution feed pump operating status, that is, detection solution feed pump whether failure, than
Such as: can by detect solution feed pump revolving speed whether determine in the normal range solution feed pump whether failure.Fault detection module
It can be an independent equipment, all solution feed pumps can be detected simultaneously；Fault detection module can also be single by multiple detections
Member is constituted, and each detection unit detects a solution feed pump.Since the fault detection of solution feed pump belongs to the prior art, many hydraulic brakes
The function is all equipped in vehicle system, therefore, fault detection module also just belongs to the prior art, also no longer illustrates here.
Following emphasis is illustrated the accident warning device of hydraulic brake system.
Warning device includes power module and alarm module, and alarm module is arranged on the current supply circuit of power module.Its
In, the acoustic-optic alarm in alarm module corresponding diagram 1；Power module includes ups power and Switching Power Supply, the electricity of ups power
The electrical energy inputs of energy output end connection switch power supply, power supply of the ups power as Switching Power Supply provide for Switching Power Supply
The electric energy output end of uninterruptible power, Switching Power Supply exports above-mentioned current supply circuit.Therefore, it is powered using ups power, it can
Guarantee to provide uninterrupted voltage for acoustic-optic alarm, promotes alarm reliability.In addition, the electrical energy inputs of ups power connect
AC input mouth (L, N) is provided with breaker between AC input mouth (L, N) and the electrical energy inputs of ups power
QK guarantees circuit safety, and further, circuit breaker Q K is second level two wires miniature circuit breaker.
Certainly, power module can also be the originally existing power module in hydraulic brake system Central Plains, in this case, the electricity
Source module is not just a part of warning device.
Warning device further includes system working connection oil pressure detection module (not shown in figure 1) and oil pressure cntrol switch P, system
Working connection oil pressure detection module is used for the oil pressure of detection system working connection, since accumulator plays benefit when working connection deficiency
The effect filled, therefore, when accumulator operates normally, the oil pressure in working connection will not become very low, only when accumulator occurs
When failure, accumulator cannot play the role of supplement, and the oil pressure of working connection just has very low possibility, therefore, pass through inspection
Survey working connection oil pressure can know accumulator whether failure.Oil pressure cntrol switch P string is located on the current supply circuit of Switching Power Supply,
System working connection oil pressure detection module control connection oil pressure cntrol switch P, should in the present embodiment when oil pressure is lower than setting value
Setting value is 7.8MPa, indicates that working connection oil pressure is too low, can determine that failure occurs in accumulator, then, control oil pressure cntrol
Switch P conducting.Therefore, when working connection oil pressure is lower than setting value, oil pressure cntrol switch P conducting, acoustic-optic alarm obtains electric, hair
Alarm signal out.In the present embodiment, system working connection oil pressure detection module and oil pressure cntrol switch P can integrate setting, for tool
There are the pressure switch of detection function, operation logic are as follows: when the pressure value detected is less than certain value, switch contact conducting, by
It is involved in this pressure switch, just no longer illustrates here in the prior art.
Warning device further includes and the one-to-one control switch of solution feed pump in system, for ease of description, the control at this
System switch is known as Fault Control switch, then, the number of the solution feed pump in system is identical as the number that Fault Control switchs, and
The two is one-to-one.Under normal conditions, the number of the solution feed pump in system is two, therefore, in the present embodiment, failure control
The number of system switch is 2, respectively corresponds contactor KM1 and KM2 in Fig. 1, and contactor KM1 and KM2 string are located at a branch
On, which is connected in parallel with oil pressure cntrol switch P.Fault detection module control connection contactor KM1 and KM2 above,
When some solution feed pump breaks down, contactor conducting corresponding with the failure solution feed pump is controlled.If solution feed pump is not complete
Portion breaks down, other solution feed pumps operated normally normally provide power for system, then, system is still able to operate normally,
Therefore, it only just alarms when all solution feed pumps break down.Accordingly, when all solution feed pumps break down,
All contactors are both turned on, then, the branch where contactor just forms an access, and acoustic-optic alarm obtains electric, sending
Alarm signal.
It can to sum up obtain, when the oil pressure of system working connection is lower than setting value 7.8MPa and/or in hydraulic disc brake system
When two solution feed pumps break down, such as when feed flow pump motor is in shutdown status, acoustic-optic alarm obtains electric, issues report
Alert signal.In addition, acoustic-optic alarm can be set inside driller control house, once alarm, operator can take in time
Measure eliminates the hidden danger for safety accident occur, plays stronger guaranteeing role to the safety of wellbore construction.
In addition, when brake system normally starts, system working connection oil pressure is usually lower when due to just starting, when it is lower than
When setting value 7.8MPa, acoustic-optic alarm can of short duration sending sound-light alarm, after oil pressure be gradually recovered it is normal after, alarm can be automatic
It releases, system worked well.
Specific embodiment is presented above, but the utility model is not limited to described embodiment.This is practical
Novel basic ideas are above-mentioned basic scheme, for those of ordinary skill in the art, introduction according to the present utility model,
The model, formula, parameter for designing various modifications do not need to spend creative work.The principles of the present invention are not being departed from
The protection scope of the utility model is still fallen with the change, modification, replacement and modification carried out in the case where spirit to embodiment
It is interior.
