Abstract
Tube well dewatering maintains control system automatically, is related to geotechnical engineering field.The utility model relates to a kind of for that can automatically control the device of precipitation depth in Deep Foundation Pit Dewatering Design and work progress.By making special switch, it is connected with two floats, flexibly controls power switch by the gravity and buoyancy of float；Meanwhile the distance between two floats are the drawdown of required pipe well well water position, and opening and closing switch, real-time control can be automatically determined whether according to the water level in practical drawdown and pipe well well；Moreover, can adjust the distance between float and motor for submerged pump as needed determines protection motor height of water level, motor is avoided to burn.
Description
Technical field
The utility model relates to the constructions of the automatic precipitation system of pipe well in geotechnical engineering field.
Background technique
Currently, the underground water level measurement and opening immersible pump and closing immersible pump that are generally used in deep basal pit tube well dewatering
It fully relies on and manually completes, for heavy construction and in the case that there is more dewatering well, not only expend huge manpower, and
And it is also difficult to accurately control the relative positional relationship in pipe well between level of ground water and immersible pump.Its limitation mainly has following
3 points:
(1) level of ground water needs personal monitoring in pipe well well, needs to put into more manpower, and not only workload is huge, and
And also it is difficult to control accurate precipitation depth.
(2) it for turning on or off diving pumping source, goes to execute after needing personal monitoring to judge, it is understood that there may be subjectivity is sentenced
Dislocation misses.
(3) cannot drawdown real-time control pipe well well water position according to actual needs, there are waste water resource, burn immersible pump
Motor increases phenomena such as precipitation cost.
Utility model content
The purpose of this utility model be design it is a kind of make special switch, it is connected with two floats, by float
Gravity and buoyancy automatic control power supply switch.
It needs personal monitoring in order to solve level of ground water in pipe well well and avoids the mistake of subjective judgement, protect motor for submerged pump
Water resource is saved with maximum possible, the utility model concrete structure design is as follows:
Tube well dewatering maintains control system automatically, it is characterised in that: by the switch being connected with two floats, according to being dropped
Spacing between the requirement adjustment float of low water level carrys out real-time control water level；Meanwhile the distance between two floats are to be wanted
The drawdown for the pipe well well water position asked can automatically determine whether to open and close according to the water level in practical drawdown and pipe well well
Switch, real-time control；Moreover, can adjust the distance between float and motor for submerged pump as needed determines that protection motor water level is high
Degree, avoids motor from burning.
The utility model utilizes the validity and real-time for guaranteeing precipitation by the automatic switch of float control, meanwhile, really
It protects immersible pump to be located under the water body of certain depth, avoids the motor for burning immersible pump.
Detailed description of the invention
Fig. 1 is the diagrammatic cross-section of the utility model.
In figure:

Specific embodiment
The utility model is further described in conjunction with attached drawing 1.
Tube well dewatering maintains system automatically, and receptacle 1 is the master switch that entire tube well dewatering maintains system automatically, normally
In the case of be to be connected to external power supply, switchgear 2 closure be entire tube well dewatering circuit connection, conversely, circuit disconnect.
The switch and closure of this system power supply are automatically controlled by switchgear 2.Switchgear 2 includes contact flat spring 5, contact support 4
With hold-down support 3；Contact flat spring 5 is fixed on hold-down support 3, and float 7 is connected by insulating cord 6 with contact flat spring 5 again.Float
7 are connected and composed by upper and lower two float units；Contact flat spring 5 is controlled by float 7 to disconnect or contact with contact support 4, is dived under water
Pump 8 is connect with contact support 4；Contact flat spring 5 and contact support 4 are when contacting, hold-down support 3, contact flat spring 5, contact support 4 with
The formation of immersible pump 8 one is closed circuit；Further, using rigid connection between upper and lower two float units.
The course of work are as follows:
The difference of the gravity and suffered buoyancy of the rising of pipe well well water position namely upper and lower two float units is less than contact flat spring
5 elastic force, contact flat spring 5 are resetted upwards, are closed, and are contacted with contact support 4, entire circuit closed, immersible pump 8 starts work of drawing water
Make；As the difference of the decline of water level namely the gravity of upper and lower two float units and suffered buoyancy is greater than the bullet of contact flat spring 5
Power, contact flat spring 5 are moved downward by the pulling force of float 7, and contact flat spring 5 and contact support 4 disconnect, and entire circuit disconnects, diving
Pump 8 stops pumping work；At this point, the distance between pump motor and following float unit are to protect height of water level；With dampening
Position continues to rise, and then repeats the above process.
It is described to can automatically detect pipe well well water position for tube well dewatering automatic control system, reduce the throwing of human resources
Enter；It is closed automatically according to control water level in well, opens power supply, so that immersible pump is started and is stopped working, save water resource；According to reality
Border needs the height of water level of reserved protection immersible pump, so that immersible pump is in pipe well well water position or less and works, avoids burning motor.
Claims (2)
