Description
Technical field
The utility model is related to electronic technology, more particularly to the alarm dress in subway dewatering engineering Well Water Level is met the tendency of in electronic technology
It sets.
Background technology
For subway engineering in constructing tunnel, many location rich groundwaters need Drilling dewatering well to drain underground water, sometimes
Underground water water yield is big, to design more mouthfuls of dewatering wells to complete work of drawing water.At work, often there is individual well power failure in dewatering well
Accident, each well is equipped with independent distribution box , And and is furnished with monitoring personnel, and since well quantity is big, distance is drawn far, so matching
Number it is more, although people is more, often there is power outage in night individual well, and main cause is that well number polygamy electricity is more random, earth's surface electricity
Cable is fragile, and motor for submerged pump burns and is not easy to find in well sometimes, causes water burst in localized tunnel, and such as processing can make not in time
At major accident.
The prior art is that on-site supervision personnel are although more, but accident causes power failure to be not easy to be found in time in well, works as tunnel
The case where being just found when a large amount of water bursts in road, cause difficulty to processing work, have can cause certain loss.Another situation is
Over one hundred mouthful of well does not know accident well accurate location, needs to well location distribution box to check one by one, expends many times.
Utility model content
The purpose of this utility model provide it is a kind of it is simple in structure, multiple well locations can be detected simultaneously, be exclusively used in subway dewatering engineering
The monitoring alarm device of well.
The purpose of this utility model can be achieved through the following technical solutions, a kind of subway dewatering engineering well warning device, described
Device includes dewatering well end device 1 and hand-held end device 2；The dewatering well end device 1 by power cord row 10, transformer 11, after
Electric appliance 12, battery 13 and wireless signal transmitter 14 form；Wherein one end of the power cord row 10 of dewatering well end device 1 and subway
Well power distribution cabinet power output end connects, and the other end of power cord row 10 connects with the input terminal of transformer 11, transformer 11
12 power end of relay termination is exported, one end of the wiring termination battery 13 of relay 12, the normally closed termination of relay 12 is wireless
Power supply one end of signal projector 14, the other end of battery 13 connect the power supply other end of wireless signal transmitter 14；It is wherein hand-held
End device 2 is made of control unit 20, reception of wireless signals unit 21, alarm unit 22, display unit 23 and battery unit 24.
The subway dewatering engineering well warning device, dewatering well end device 1 is more than two mutually independent devices, described
Hand-held end device 2 can receive and distinguish the signal that different precipitation well end device 1 is sent out.
The utility model has the advantage of it is simple in structure, multiple well locations can be detected simultaneously save a large amount of manpower.
Description of the drawings
Fig. 1 is the dewatering well end device principle schematic of the utility model；
Fig. 2 is the handheld terminal principle of device schematic diagram of the utility model.
Specific implementation mode
As shown in Figures 1 and 2, subway dewatering engineering well warning device, including several dewatering well end devices 1 and hand-held end device 2；
The dewatering well end device 1 is made of power cord row 10, transformer 11, relay 12, battery 13 and wireless signal transmitter 14；
One end of the wherein power cord row 10 of dewatering well end device 1 connects with subway well power distribution cabinet power output end, power cord row's 10
The other end connect with the input terminal of transformer 11,12 power end of output relay termination of transformer 11, relay 12 connects
Line end connects one end of battery 13, power supply one end of the normally closed termination wireless signal transmitter 14 of relay 12, battery 13 it is another
End, connects the power supply other end of wireless signal transmitter 14；Wherein hand-held end device 2 is by control unit 20, reception of wireless signals list
Member 21, alarm unit 22, display unit 23 and battery unit 24 form.
There are one difference code, hand-held end devices 2 to receive for the wireless signal transmitter 14 of each dewatering well end device 1
The signal that wireless signal transmitter 14 emits, and the display of different difference codes is given on the display unit 23.
The course of work of the utility model is：General subway dewatering well is designed with subway well power distribution cabinet, suction pump, water level control
The devices such as device processed, when water level exceeds preset standard, water level controller can control the work of suction pump, in its course of work
In, can often draw water failure of pump, and water level abnormality etc. can all make the tripping power-off of subway well power distribution cabinet, to cause in localized tunnel
The accident of water burst.
Dewatering well end device 1 is arranged in the subway Jing Pei electricity Gui Chu of each subway dewatering engineering well in the utility model,
And one end of the power cord of dewatering well end device 1 row 10 is connected with subway well power distribution cabinet power output end；Just
Subway well power distribution cabinet makes relay 12 be in obtain electricity condition by power cord row 10, transformer 11 in the case of often, at this time relay
12 normal-closed end, which is in, to be disconnected, and wireless signal transmitter 14 must not electricity.After subway well power distribution cabinet, which trips, to be powered off, transformer 11 loses
The power supply for removing subway well power distribution cabinet, to make relay 12 be in power failure state, the normal-closed end of relay 12, which is in, at this time is closed,
It connects battery 13 to power for wireless signal transmitter 14,14 work once electrified of wireless signal transmitter sends out the well location operation irregularity
Alarm signal.Hand-held end device 2 shows well location in display unit 23 and alarm unit 22 is reported after being connected to the alarm signal
Alert, monitoring personnel rushes to well location timely processing at the first time, and tunnel internal cause dewatering well termination of pumping is avoided to cause a serious accident.
