Abstract
The utility model discloses a high-lift drainage device of a sump, which comprises a drainage pump, a control unit and two liquid level sensors, wherein the control unit is electrically connected with a power source input terminal of the drainage pump; and the two liquid level sensors are connected with a signal input terminal of the control unit through conducting wires and arranged in the upper and lower parts of the sump respectively. The high-lift drainage device is characterized in that a submersible pump is fixed at the bottom of the sump; a water outlet of the submersible pump is communicated with a water inlet of the drainage pump, and a power source input terminal of the submersible pump is electrically connected with the control unit. The high-lift drainage device has the following advantages: the submersible pump communicated with the drainage pump is fixed at the bottom of the sump, the control unit is used to control the sequential starting of the submersible pump and the drainage pump, the suction length and the drainage amount can be greatly increased, the depth and the water storage amount of the sump can be increased, the depth of the sump can reach 50 meters to 100 meters, coal mine enterprises do not need to draw water anytime, and the electricity expenses and the coal cost are saved.
Description
Technical field
The utility model relates to a kind of dewatering installation, particularly a kind of sump high suction depth dewatering installation that uses in coal mining enterprise.
Background technology
Coal mining enterprise has in mining process and descends swelling to go out in large quantities, and the underground water that will gush out usually at present flows into sump by the ditch that begins to rehearse in the mode that flows naturally, by dewatering installation water is concentrated then to drain into ground.Existing mining dewatering installation is by the drainage pump that is located at the sump outside, connects the control module of drainage pump and is inserted in the sump and constitutes with liquid level sensor that control module electrically connects.This dewatering installation is because drainage pump suction journey is limited, only be about 4 meters, therefore the sump degree of depth is more shallow, generally have only about 7 meters, cause the sump moisture storage capacity little, any period at " peak, paddy, flat " all draw water at any time, under the constant prerequisite of power consumption, increased electricity charge expenditure and mining costs like this; If the increase of the sump degree of depth will be caused long-term ponding in the sump, can't be with the water emptying of bottom.And because the sump moisture storage capacity is little, in case metalling run out in the colliery, during water leak accident, does not have more time to allow the workman escape, casualty accident takes place very easily.
Summary of the invention
Technical problem to be solved in the utility model is that a kind of suction journey height will be provided, and displacement is big, can increase the sump high suction depth dewatering installation of the sump degree of depth.
The technical solution of the utility model is as follows: it comprises drainage pump, control module and liquid level sensor, the power input of control module and drainage pump electrically connects, liquid level sensor is two and is connected by lead with the signal input part of control module respectively, two liquid level sensors are located at the upper and lower part in the sump respectively, its special character is: be installed with submersible pump at the sump inner bottom part, the submersible pump delivery port is communicated with the water inlet of drainage pump by pipeline, and the power input and the control module of submersible pump electrically connect.
The utility model has the advantages that: owing to be installed with the submersible pump that is communicated with drainage pump at the sump inner bottom part, successively start by control module control submersible pump and drainage pump, can increase greatly and inhale journey and displacement, therefore this dewatering installation is inhaled the journey height, displacement is big, can increase the sump degree of depth and sump moisture storage capacity, and the sump degree of depth can reach 50～100 meters, so coal mining enterprise need not to draw water at any time, can save electricity charge expenditure and mining costs.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Among the figure: drainage pump 1, control module 2, submersible pump 3, carriage 4, pipeline 5, liquid level sensor 6, sump 7.
The specific embodiment
As shown in the figure, this sump high suction depth dewatering installation has one to be installed in ground drainage pump 1 and control module 2, control module 2 electrically connects with the power input of drainage pump 1, in sump 7, be provided with two liquid level sensors 6, two liquid level sensors 6 are located at the upper and lower part in the sump 7 respectively, and are connected by lead with the signal input part of control module 2 respectively.Be fixed with carriage 4 at sump 7 inner bottom parts by stone bolt, submersible pump 3 is installed on carriage 4, the delivery port of submersible pump 3 is communicated with the water inlet of drainage pump 1 by pipeline 5, and the power input of submersible pump 3 and control module 2 electrically connect.
When liquid level reaches the liquid level of setting, transmit signal by superposed liquid level sensor 6 and give control module 2, control module 2 control submersible pumps 3 start, after submersible pump 3 is started working, water enters into drainage pump 1 by pipeline 5, and control module 2 control this moment drainage pumps 1 are started working, when the liquid water potential drop in the sump 7 when being positioned at the liquid level sensor 6 of bottom, liquid level sensor 6 transmits signal and gives control module 2, and control submersible pump 3 and drainage pump 1 quit work.
