Description
【Technical field】
The utility model belongs to field of electrical equipment, is related to a kind of automatic draining device for cable trench.
【Background technology】
Cable trench water collecting hardly possible row's problem, is the universal phenomenon of various regions substation management centre, is built mainly due to transformer station
If when it is lack of standardization on drainage pattern, in addressing to surrounding enviroment develop and change consider it is insufficient, left cable duct product
The problem of Shui Wu roads can be arranged.The effect of cable duct is：First, the special underpass of cable is formed, substation cable discharge is reduced
The space of occupancy；2nd, protection cable will not by artificial property or naturality pressure injury；3rd, it is prevented effectively from erosion corrosion
Cable, causes cable bad；4th, prevent cable from being soaked in water, keep insulating properties good inside and outside cable.When entering thunderstorm
During season, substantial amounts of rainwater flows into inspection shaft by cable duct, and the water level of inspection shaft constantly rises, and it is in continue to cause water level in cable duct
Property rise.If to ponding without timely pump drainage, ponding will soak cable.Cable soaks by ponding for a long time, its electricity
, after dehydration, easily there is the damage of dry and cracked property in the hydrophobicity performance reduction of cable crust.If if the cable sheath soaked by ponding has
Damage is worn and torn, and ponding further can inwardly corrode, and cause secondary circuit short trouble occur.So as to operation that can be to transformer station
Great potential safety hazard is caused, even more serious meeting makes ponding pour in down a chimney hyperbaric chamber, triggers power grid accident.
By long-term live follow-up investigation, find to flow into the sewage complicated of cable duct from ground, it is most likely that have
Corrode sexual element, corrosive damage easily is caused to cable.In real work, no matter transformer station is unattended station or had
People station on duty, is accomplished by arranging special messenger to go to transformer station to draw water cable duct into the rainy day.Because once there is dry tap in water pump,
The coil of motor will be burnt out, it is desirable to which staff must just have a power failure, directly to water pump after water level and water pump maintain an equal level in cable duct
Raised again to water level, could next time be drawn water, greatly affected operating efficiency, occupy a large amount of manpowers, while pole
Device damage is easily caused, triggers production accident.

The automatic pump drainage of ponding in cable duct.
To reach above-mentioned purpose, the utility model is achieved using following technical scheme：
A kind of automatic draining device for cable trench, including the liquid level sensor and water pump being arranged in cable duct, level sensing
Device and water pump are electrically connected with the controller, and controller judges the liquid level signal of liquid level sensor feedback, if liquid level reaches higher limit,
Work order is sent to water pump, if liquid level reaches lower limit, standby command is sent to water pump；The outlet connection outlet pipe of water pump
Road, the end of outlet conduit is delivery port.
The utility model, which is further improved, to be：
220V power input ports are provided with the panel of controller.
The warning lamp with buzzer is connected with the signal output part of controller, warning lamp is in shinny shape in pump working
State, buzzer is in generating state.
The super stream automatic safety device automatically powered off when electric current is more than rated operational current 60% is provided with water pump.
The motor of water pump is single-phase pump motor, and can show that operating current and motor broken string are indicated in real time.
It is also associated with starting for not timing the hand switch of water pump in the control end of controller.
Compared with prior art, the utility model has the advantages that：
The utility model control unit can realize automatic operation mode and manual work pattern；Sensed using liquid-level switch
Device, the stable strong antijamming capability of performance；It is controlled by single-chip microcomputer, data control stablizes accurate with analysis；Control unit has
There is reset to reset function, only retain automatic mode and super stream 80% is automatically powered off；The super automatic automatic protection of stream of individual event pump motor
Device, surpasses stream protective current adjustable；Water pump water shortage automatic protection, excessive low water level protection current adjustment；Pump motor has operating current
Indicate in real time, motor burn out detection indicates function；The draining upper limit, offline water level in cable duct can be adjusted arbitrarily, be realized simultaneously
Water shortage cutout automatic protection；The utility model can realize that water level is supervised in real time in the monitoring in real time of cable duct draining current and cable duct
Survey；Sound and light alarm starts under working condition, and reminding in operation maintenance personnel's cable duct has water and just in draining；Finally, this practicality
New small volume, (without changing device structure) easy for installation is dependable performance, easy to operate.
【Brief description of the drawings】
Fig. 1 is overall structure diagram of the present utility model.
Wherein：1- controllers；2- liquid level sensors；3- warning lamps；4- hand switches；5- water pumps；6- delivery ports.
【Embodiment】
The utility model is described in further detail below in conjunction with the accompanying drawings：
Referring to Fig. 1, the utility model automatic draining device for cable trench, including controller 1, and it is electric with controller 1 respectively
The liquid level sensor 2 and water pump 5 of connection；The signal output part of controller 1 is connected with warning lamp 3, and control end is connected with hand switch
4；The outlet connection outlet conduit of water pump 5, the end of outlet conduit is delivery port 6.Water pump 5 is connected with single-phase pump motor, single
Super stream automatic safety device is provided with phase pump motor, the super stream protective current value of single-phase pump motor is adjustable to be indicated；
The utility model can arbitrarily adjust the upper limit, lower limit water level, realize that water level is monitored in real time, and single-phase pump motor
Operating current can be indicated in real time, and indicate function with motor burn out detection；The industrial and mineral that the utility model is applied to draining is looked forward to
The occasions such as industry, urban architecture basement, elevator pit, cable duct are used,
Structural principle of the present utility model：
Controller of the present utility model, the setting for carrying out draining parameter, allows drainage arrangement normally to be arranged
Water conservancy project is made；
Warning lamp, in pump working, lamp to be bright and sends sound, lamp when controller shutdown or water pump automatic stand-by state
Go out；
Liquid level sensor, the height for sensed water level；
Hand switch, the startup water pump (avoiding water pump from being chronically at holding state) for not timing.
The course of work of the present utility model：
External power source is initially switched off before installation, power line, water pump line and signal connecting line is connected.Controller is placed
In place, controller should first be off state, then carry out wiring；The control line of liquid level sensor two and signal wire pair
