Abstract
The utility model relates to an automatic drainage system of a cable tunnel, which belongs to the field of drainage. A water collecting well (2) is arranged in the lowest position of the cable tunnel for collecting accumulated water in the well. Two submersible pumps of the submersible pump A (3) and the submersible pump B (4) are mounted in the water collecting well, a drainage pipe (6) of the submersible pump A (3) and a drainage pipe (7) of the submersible pump B (4) are connected with a main drainage pipeline (3) through a connecting pipeline (8) in a parallel connection way, and a high water level probe (9), a low water level probe (10) and a zero water level probe (11) are simultaneously arranged in the water collecting well (2). When the water level is low, the submersible pump A (3) is started for drainage, when the water level is high, the submersible pump B (4) is simultaneously started for drainage. The automatic drainage system is characterized by high degree of automation, timely drainage and large discharge capacity, thereby potentially ensuring the safety of cables in the tunnel.
Description
Technical field
The utility model relates to and belongs to the draining field, particularly a kind of automatic drainage system for cable tunnel.
Background technology
At present, known cable tunnel draining is to adopt artificial drainage.And artificial drainage can't resolve the needs of a large amount of ponding and rainy day draining at all.If the water yield is big or draining is untimely, will the facility in cable tunnel and the tunnel be worked the mischief.
Summary of the invention
The utility model automatic drainage system for cable tunnel, technical problem to be solved is in order to overcome the deficiency of existing cable trench drainage pattern: the problem that can not in time discharge a large amount of ponding, and the employing forced drainage system, can in time discharge a large amount of ponding, rainwater, effectively ensure the safety of tunnel and internal unit.
The technical scheme that its technical problem that solves the utility model adopts is: the lowest part in the cable tunnel is provided with a collecting well, and ponding will concentrate in the well.Two submersible pumps are installed in collecting well: submersible pump A, submersible pump B if can use simultaneously when water is big, increases displacement.Cable tunnel and main drainpipe road are dug through connecting pipe stube cable tunnel and the main drainpipe road made with pipe of cement.Delivery port with submersible pump is connected with the main drainpipe road again: the gutter of the gutter of submersible pump A and submersible pump B links to each other with the main drainpipe road by connecting pipe in parallel.In collecting well, establish two high low water stage measuring points, be connected with the automatic open system of water pump.In the water level uphill process: when water level arrived the low water stage probe positions, submersible pump A opened.When the too big water pump of the water yield be can not be completed the draining task, water level will rise, and when the paramount water-level probe of water level position, submersible pump B opens, and two water pump drainings simultaneously at this moment are with the ponding emptying in the tunnel.In the drawdown process: when water level drops to low water stage probe height when following, submersible pump B is out of service.When water level continues to drop to zero level probe height when following, submersible pump A is also out of service.
The beneficial effects of the utility model are can discharge ponding, rainwater in time, and realize the automation control of drainage system.
Description of drawings
Fig. 1 is a cable tunnel drainage system structure chart.
Fig. 2 adopts the full-automatic water level control of DF-96 wiring diagram.
Fig. 3 adopts the little electric space-time switch wiring diagram of TB-10.
Among the figure: 1. cable tunnel, 2. collecting well, 3. main drainpipe road, 4. submersible pump A, 5. submersible pump B, the 6. gutter of submersible pump A, the 7. gutter of submersible pump B, 8. connecting pipe, 9. high water level probe, 10. low water stage probe, 11. zero levels probe.
The specific embodiment
The lowest part of (1) is provided with a collecting well (2) in the cable tunnel, and two submersible pumps: submersible pump A (3), submersible pump B (4) are installed in collecting well.Cable tunnel (1) and main drainpipe road (3) is dug through, make connecting pipe (8) stube cable tunnel (1) and main drainpipe road (3) with pipe of cement.Delivery port with submersible pump is connected with the main drainpipe road again: the gutter (7) of the gutter of submersible pump A (6) and submersible pump B links to each other with main drainpipe road (3).
High water level probe (9), low water stage probe (10) and zero level probe (11) are set in collecting well (2).E-is collecting well high water level control point, and water level rises to E point water level, and water contacts with high water level probe (9), and water level controller is opened submersible pump B (7) automatically.D-is collecting well low water stage control point, if drawdown to D point water level when following, low water stage is popped one's head in (8) and water disengages, water level controller cuts out submersible pump B (7) automatically.When water level rose to D point water level, low water stage probe (8) contacted with water, and water level controller is opened submersible pump A (6) automatically.C-is collecting well zero level control point, and when drawdown was following to C point water level, zero level probe (11) disengaged with water, and water level controller cuts out submersible pump A (6) automatically, and A, B point does not connect.
The directly wiring of control mode: controlled electrical equipment is single phase power supply, and power consumption is no more than the rated capacity (resistive load 25A) of this switch, can adopt direct control mode.
Claims (3)
1. automatic drainage system for cable tunnel, it is characterized in that: it comprises cable tunnel (1), the collecting well (2) that the lowest part of (1) is provided with in the cable tunnel, submersible pump A (3), submersible pump B (4) are installed in the collecting well (2), the gutter (6) of submersible pump A (3) and the gutter (7) of submersible pump B (4) are connected with connecting pipe (8), and connecting pipe (8) links to each other with main drainpipe road (3).
2. automatic drainage system for cable tunnel according to claim 1 is characterized in that: collecting well (2) is arranged on the lowest part of cable tunnel (1).
3. automatic drainage system for cable tunnel according to claim 1 is characterized in that: with the connecting pipe (8) that pipe of cement is made, come stube cable tunnel (1) and main drainpipe road (3).
