Abstract
The invention discloses a drainage control device developed for removing ponding of railway bridges. The device can control the highest water level in a set range, has an automatic protection function, and realizes manage-free automatic drainage. The device comprises power input interfaces a, b and c, a float switch AN1, a float switch AN2, a relay J1, a relay J2, a relay J3 and an electric pump M controlled by the relays. A high level float A is suspended below the float switch AN1, and a low level float B is suspended below the float switch AN2.
Description
Technical field
The present invention is a kind of draining automaton, and the ponding eliminating that is used for the railway bridges and culverts can realize self-insurance, automatic control unattended.
Background technology
For satisfying fast development of national economy, train raises speed again and again, and railway interests is the traffic convenience that takes into account traffic safety and railway both sides resident and industrial and agricultural production, with original climb, the level crossing reconstruction is the culvert of passing by on one's way.But, low-lying at the bottom of the most hole of these culverts, normal because of rain, defrost or ground water seepage ponding, make troubles to pedestrian and vehicle.The culvert draining become to make things convenient for trackside resident traffic, ensure local economic development, avoid the major issue of railway and local contradiction.For this reason, railway interests has also made very big effort, when building culvert, also is provided with dewatering installation.These dewatering installations are difficult to bring into play its due effect because of no staff on duty, as send staff on duty, and the culvert number is various on the way can cause great amount of manpower waste to country again for railway.At present, have polytype to be used for self-draining water level controller on the market, but their structure is inappropriate in muddy water and uses, within a short period of time is promptly ineffective; Do not have automatic protection functions again, cause electric water pump phase-deficient operation very easily to burn motor, in application, be difficult to carry out unattended in case open-phase fault appears in supply line.
The present invention is exactly the automatic control device that has the self-protection function, can in muddy water, use, can realize automatic draining exempt from the management.
Summary of the invention
The purpose of this invention is to provide a kind of simple in structurely, overcome the defective of prior art, can carry out unattended, be applied in the automation dewatering installation in the muddy water.
For realizing above-mentioned purpose, the technical scheme that the present invention adopts is:
The bridges and culverts self-draining arrangement of passing by on one's way has power supply a, b, c input wires mouth, Float switch AN1, Float switch AN2, relay J 1, relay J 2, the electric water pump M of relay J 3 and control thereof.The bottom of Float switch AN1 suspends high-order cursory A in midair, the cursory B of bottom's suspention low level of Float switch AN2.
Relay termination J1 behind the preceding termination power input line c of Float switch AN1, the switch J1-1 and the Float switch AN2 of the back termination parallel connection of relay J 1, the back termination power input wires a of switch J1-1 and Float switch AN2.The high cursory A of the following side suspension of Float switch AN1, the following side suspension of Float switch AN2 hangs down cursory B.Termination normally closed switch J1-2 behind the preceding termination power input wires c of relay J 2, the back termination power input wires a of normally closed switch J1-2.Termination switch J2 behind the preceding termination power input wires b of relay J 3, the back termination power input wires a of switch J2.Termination electricity water pump M behind the preceding termination power input wires a of the three switch J3 of company, b, the c.
Description of drawings
Fig. 1 is a line construction sketch map of the present invention.
The specific embodiment
Below in conjunction with accompanying drawing and specific embodiment the present invention is further described: as shown in Figure 1; Relay termination J1 behind the preceding termination power input line c of Float switch AN1 wherein; The switch J1-1 and the Float switch AN2 of the back termination parallel connection of relay J 1, the back termination power input wires a of switch J1-1 and Float switch AN2.The high cursory A of the following side suspension of Float switch AN1, the following side suspension of Float switch AN2 hangs down cursory B.Be at the sump water level and set lowest water level or when following; Gao Shui floats A and is all suspended state with low cursory B; Their gravity causes Float switch AN1, Float switch AN2 closure with power supply a, power supply c cut-in relay J1, and relay J 1 is broken off switch J1-1 adhesive with normally closed switch J1-2; Because of rain, snow melt or ground water seepage water level go up gradually, and low cursory B is floated, Float switch AN2 breaks off.Float switch AN1 in the closure state and switch J1-1 still make the power supply of relay J 1 keep path, and normally closed switch J1-2 keeps off-state.Water level continue to go up, and high cursory A is floated when setting peak level, Float switch AN1 breaks off the power path of relay J 1; Switch J1-1 breaks off immediately; Normally closed switch J1-2 is the operating circuit of engage relay J2 immediately, and with switch J2 adhesive, switch J2 connects the operating circuit of relay J 3; Three connect switch J3 connects the operating circuit of electric water pump M, and pump operation carries out draining.
Water level descends gradually, at first makes high cursory A recover suspention, and Float switch A1 is closed; But switch J1-1 and Float switch A2 still keep off-state relay J 1 not work, and normally closed switch J1-2 keeps the operating circuit of engage relay J2; Switch J2 keeps adhesive, the working power of switch J2 guard relay J3, and three connect the working power that switch J3 keeps electric water pump M; Water pump remains in operation, and draining is still being carried out.
Water level continues to descend, and until reaching the setting lowest water level, low cursory B recovers suspended state, Float switch AN2 closure with power supply a cut-in relay J1, and relay J 1 is broken off switch J1-1 adhesive with normally closed switch J1-2; Normally closed switch J1-2 breaks off relay J 2 working powers, and relay J 2 armature release-push J2 break off relay J 3 working powers, and relay J 3 quits work three of its control is connected switch J3 disconnection, and electric water pump breaks away from power supply, and this draining finishes.
So repeatedly, water level is controlled at below the setting peak level all the time.When open-phase fault appears in supply line:
1, lack a phase: all relays are neither can work, and water pump connects to advance circuit certainly.
2, lack the b phase: relay J 3 can not be worked, and water pump connects to advance circuit equally.
3, lack the c phase: relay J 2 is not worked, and relay J 3 also can not be worked, and water pump still connects to advance circuit.So guarantee electric water pump can phase-deficient operation to ensure the safety of drainage.
