Description
Technical field
The utility model relates to the water-pumping/draining device in a kind of counter-slope constructing tunnel, and by a kind of multistage water-pumping/draining system of this installation composition.
Background technology
In constructing tunnel, as adopted counter-slope, inclined shaft or vertical shaft scheme, unavoidably all existing and adopt plash central drainage problem at present, is all generally to adopt electronic pumping equipment to carry out manual drainage.But in constructing tunnel process, water yield exists uncertainly, and the frequency of draining is respectively not quite similar again, need to arrange that special messenger is on duty to be kept an eye on, cause a large amount of costs of labor.
During general electronic pumping system design, all by maximum flooding quantity in hole, consider Model of pump, its power is generally larger, causes water pump heavy-duty service in whole work progress, causes a large amount of energy wastes.
Summary of the invention
The purpose of this utility model is to provide a kind of according to the automatic device of controlling many water pump water-pumping/drainings of water yield size, and this device can multistage use in counter-slope constructing tunnel.
For reaching above object, the utility model takes following technical scheme to be achieved:
The automatic water-pumping/draining device in a kind of counter-slope tunnel, it is characterized in that, comprise that be arranged in counter-slope tunnel near a ponding well two with charging pump, each water pump controls the unlatching of this water pump and cuts out by a self-resetting switch, each pump outlet all connects main pipeline by an one way valve and subtube, and main pipeline is exported to outside tunnel; The self-resetting switch of each water pump is all connected with a ball float in ponding well by a tightrope, and arranging highly not etc. of each ball float, increases successively from low water line to high-water line.
In such scheme, described water pump is 3～4.The difference in height of described each ball float equates.
The multistage water-pumping/draining system in counter-slope tunnel, adopts two automatic water-pumping/draining devices in above aforementioned counter-slope tunnel to form, and simply the main pipeline in the automatic water-pumping/draining device of low level ponding well is passed in high-order ponding well, and the rest may be inferred, realizes multistage water-pumping/draining.
Compare existing construction method, the utility model has the advantages that:
1, simple installation, technical difficulty is low;
2, without manually on duty, do not need cost of labor;
3,, without adopting high powered water pump, only need select a plurality of small-power water pumps according to water yield size;
4, according to water yield size automatically controlled water pump, open quantity, energy conservation.
Accompanying drawing explanation
Fig. 1 is an embodiment of the present utility model (four water pumps) structural representation.

In Fig. 1, Fig. 2: 1, low water line; 2, high-water line; 3, ball float; 4, tightrope; 5, self-resetting switch; 6,7, cable; 8, indicator lamp; 9, water pump; 10,11, subtube; 12, one way valve; 13, main pipeline; 14, ponding well.
The specific embodiment
With reference to figure 1, the automatic water-pumping/draining system in a kind of counter-slope tunnel, comprise four water pumps (M0, M1, M2, M3) that are arranged in one, counter-slope tunnel ponding well 14, each water pump, as water pump 9 (M0), by a self-resetting switch 5, controlled the unlatching of this water pump and closed, it is defaulted as closed condition.Each water pump, as water pump 9 (M0) delivery port adopts flange to be connected with one way valve 12 by subtube 10, one way valve 12 adopts flange to be connected by subtube 11 with main pipeline 13 again, one way valve 12 is controlled current and only to main pipeline 13 directions, is flowed, and main pipeline outlet extends to (in river) outside tunnel.The self-resetting switch of each water pump is connected with the ball float of differing heights in ponding well 14 by a tightrope 4 respectively, and to control water pump usage quantity, ball float height considers according to design current velocity, and its height can pass through tightrope length adjustment.Water pump is three-phase synchronous motor.
The control principle of Fig. 1 system is, ball float 3 is with constant weight and can in water, automatically float, and the water yield is when low water line 1 is following, and ball float 3 is because naturally drooping, by tightrope 4, pull self-resetting switch 5, disconnecting circuit, water pump M0 quits work, and the water yield surpasses after low water line 1, ball float 3 is because of buoyancy floating, tightrope 4 is loosening, and self-resetting switch 5 Natural closures start water pump M0 water-pumping/draining; When the water yield continues to increase, ball float 3-1 floating, self-resetting switch 5-1 Natural closure, starts water pump M1 water-pumping/draining; When the water yield increases again, ball float 3-2 floating, self-resetting switch 5-2 Natural closure, starts water pump M2 water-pumping/draining; The water yield when increased again, ball float 3-3 floating, self-resetting switch 5-3 Natural closure, starts water pump M3 water-pumping/draining.
With reference to figure 2, the automatic water-pumping/draining system of Fig. 1 embodiment can be used for the relay water-pumping/draining of a plurality of differing heights ponding wells (in figure being two) in counter-slope tunnel, simply the main pipeline 13 in the automatic water-pumping/draining device of low level ponding well is passed in high-order ponding well, the main pipeline outlet of the automatic water-pumping/draining device of high-order ponding well extends to outside tunnel.The rest may be inferred, and the main pipeline of the automatic water-pumping/draining device of high-order ponding well passes in the 3rd ponding well of high position more can realize three grades of above water-pumping/drainings.
