Many details are explained in the following description in order to fully understand the utility model, still, this is practical
Novel to be implemented using other modes described herein are different from, therefore, the utility model is not limited to be described below
The limitation of the specific embodiment of specification.
Embodiment, as shown in Figure 1, Figure 2 and Figure 3, construction of hydro project water-proof drainage device provided by the utility model, packet
Pedestal 1 is included, organism 2 is set on the pedestal 1, water pump 3 and motor 4, the water pump 3 and water outlet are provided in the body 2
Pipe 5 connects, and is provided with the water inlet pipe 6 being connected to outlet pipe 5 on the body 2.Wherein, pedestal 1, body 2, water pump 3, motor 4
And outlet pipe 5, water inlet pipe 6 are the components of comparative maturity in the prior art, the present embodiment is not repeating.The utility model emphasis
It is that the strainability of the control and whole device to the water level in the distribution form of water inlet pipe 5, outlet pipe 5 proposes to improve, into
And pump consumption is effectively reduced, extend the service life of whole device.
In construction of hydro project water-proof drainage device provided by the utility model, the shape of the body 2 is cylindrical body, institute
It states and is provided with intake antrum 7 and valve cavity 8 in body, body height direction is provided with multiple ring pipes 9 in the intake antrum 7,
Be connected between each ring pipe 9 with vertical tube 13, it is symmetrical on each ring pipe 9 that there are two water inlet pipes 6, and this two
Have in a water inlet pipe and be provided with pressure sensor 12 on one, multiple electric control valves 10 and control are provided in the valve cavity 8
The controller (being not drawn into figure) of electric control valve 10 processed, the circle distribution on the body 2 along body 2 have multiple screen pipes 11,
The screen pipe 11 is connected to ring pipe 9 and is provided with the first filter screen inside it.
More specifically, screen pipe 11, ring pipe 9, vertical tube 13, water inlet pipe 6 and outlet pipe 5 may be constructed complete draining
Channel, annular tube 9 and vertical tube 13 are distributed in intake antrum 7, and main part and electric control valve 10 setting of water inlet pipe 6 exist
In valve cavity 8；Each pressure sensor 12 detects the level pressure on a water inlet pipe for controller analysis, wherein this reality
With the controller model MAM-330 of novel offer, the model PT4626 of pressure sensor, the pressure sensor and control
It is connected between device by PT124B-282 transmitter the output signal of pressure sensor is converted to electric signal to effectively control
Electric control valve processed, each electric control valve 10 can control the outlet pipe of a height, and in other words, each electric control valve 10 can be with
It will be truncated with the water flow in the water inlet pipe and outlet pipe of sustained height where it, the water in water inlet pipe 6 made not flow to corresponding height
Outlet pipe 5.First filter screen is used to filter wait the silt in draining.
The working principle of the present apparatus is whole device to be placed in cofferdam ponding region, wait drain in water pump 3 and motor 4
Under the action of pass sequentially through screen pipe 11, ring pipe 9, vertical tube 13, water inlet pipe 6 and outlet pipe 5, the water outlet of the water pump 3
Water is discharged to except cofferdam by connection outer water tube；During drainage works carry out, pressure sensor 12 will be real-time monitored
Level pressure send controller to, controller closes the electric control valve 10 under sufficiently high water level according to preset data
It closes, that is, closes the outlet pipe of certain altitude；With being gradually reduced for water level, controller beats corresponding electric control valve 10
It opens, 3 continuous pumpage of water pump.In this case, water pump 3 is always and draws water from pent 5 or more outlet pipe, but from water pump
The water of the main still higher position from real-time ponding of the water taken away in 3, greatly reduces the consumption power of motor 4；Meanwhile
Still need the water arranged in each ring pipe 9 and vertical tube 13, provides upward pressure for minimum level in outlet pipe 5, into
One step reduces the power consumption of water pump 3.

The strainability of whole device is improved, to reduce the abrasion in the pipeline of ponding process, main is to reduce water pump 3
In impact wear, be able to extend whole device service life.
In order to reduce pump energy consumption, each electric control valve 10 provided by the utility model respectively corresponds two on sustained height
A water inlet pipe 6, and the valve body of electric control valve 10 is cylindrical body, and in this case, controller issues corresponding electrically-controlled valve after instruction
The truncation simultaneously of door 10 and its sustained height, by two water inlet pipes flow to the water of outlet pipe, to guarantee that the water that water pump 3 extracts begins
Water on pent outlet pipe water level eventually, to reduce by 3 power consumption of water pump.
In order to which the pressure for being subject to body outer wall and internal part guarantees balanced, each annular provided by the utility model
The screen pipe 11 of 4 intervals, 90 degree of distributions is provided on pipe 9, in this case, the pressure that the outer wall of body 2 itself is subject to is more equal
Weighing apparatus, meanwhile, 13 uniform force of ring pipe 9 and vertical tube, and then the service life of whole device can be extended.
Further, the water inlet pipe 6 in same level height is set two by the utility model, and connects with ponding
The screen pipe 11 of touching is distributed with multiple, and water inlet pipe 6 and screen pipe 11 are interleaved, can become silted up in this way to avoid silt in water inlet pipe
6 with the junction of ring pipe 9, improve strainability to the maximum extent；Meanwhile the caliber of the water inlet pipe 6 is less than ring pipe 9
Caliber can amplify the active force that water level is applied to outlet pipe bottom liquid level in this way, to reduce the power consumption of water pump 3.
The above descriptions are merely preferred embodiments of the present invention, is not to make other forms to the utility model
Limitation, any person skilled in the art is changed or is modified as possibly also with the technology contents of the disclosure above equivalent
The equivalent embodiment of variation is applied to other fields, but all without departing from the content of the technical scheme of the utility model, according to this reality
With novel technical spirit any simple modification, equivalent variations and remodeling to the above embodiments, it is practical new to still fall within this
The protection scope of type technical solution.
