In figure: 1 underground hidden pipe, 2 flexible pipes, 3 water inlets, 4 clips, 5 tank lid, 6 water storage boxes, 7 rules, 8 water meters, 9 electromagnetic pressure control valve doors, 10 drainpipes, 11 piezoresistive pressure sensors, 12 spiral bottoms, 13 electric wires, 14 power connections.
Embodiment
Below in conjunction with accompanying drawing and embodiment, the present invention is described in further detail:
As shown in the figure, a kind of collection, measurement integrated device that is applicable to the draining of underground hidden pipe low discharge, comprises communication apparatus, captation and measuring equipment.Described communication apparatus comprises that a flexible pipe 2, coupled caliber are the underground hidden pipe 1 of 6 cm, the caliber water inlet 3 that is 2cm and the clip 4 that is stuck in flexible pipe 2 two ends, the front end of described flexible pipe 2 is connected with the outlet water at tail end mouth of underground hidden pipe 1, and there is a clip 4 to be blocked, described underground hidden pipe 1 is imbedded in apart from earth's surface 60cm-80cm, hidden pipe 1 is with a series of apopore, the aperture of apopore is 3mm, and top layer is surrounded by geotextile, the end of described flexible pipe 2 is connected with the water inlet 3 of water storage box 6, also has a clip 4 to block; Described captation main body be one by the transparent PP C pipe of diameter 10cm, high 50cm, made cover water storage box 6, and a spiral bottom 12 is installed in bottom, certain interval of time opens it and removes residue in water thing, prevent from resulting in blockage, left hand external is installed a range 30cm, the rule 7 of minimum scale 1mm, inside, left side arranges a piezoresistive pressure sensor 11, its setting position is determined according to the minimum flow measuring value of water meter used, right side sets out the mouth of a river, and described water delivering orifice is connected with measuring equipment; Small water meter 8 and electromagnetic pressure control valve door 9 on described measuring equipment comprises a drainpipe 10 and fixes a drainpipe, the specification of described small water meter 8 is determined according to place environment actual conditions, described electromagnetic pressure control valve door 9 joins by electric wire 13 with pressure inductor 11, and by the switching of its by-pass valve control, when electric weight is not enough, by power connection 14, by external power supply, give in time its electric energy supplement.
In the present invention, according to place environment, utilize the minimum flow permissible value of water meter 8 used to calculate corresponding water level according to the floorage of water storage box, piezoresistive pressure sensor 11 is arranged on higher than this to position more than water level, this device is got 15 cm end of apart from, carrys out the switching of controlled pressure by-pass valve control 9 by induction hydraulic pressure.Under normality, namely in drain discharge situation seldom, water level in water storage box 6 is very low, water outlet is in closed condition, increase along with closed drainage flow, water level in water storage box 6 raises gradually, hydraulic pressure also increases gradually, while rising to touching piezoresistive pressure sensor 11, sensor reacted and to some extent in the preparatory stage, when water level rises to the position that water tank is higher (apart from pressure inductor 20cm), piezoresistive pressure sensor 11 can be given electromagnetic pressure control valve door 9 by emissioning controling signal " 1 ", thereby opening water delivering orifice discharges a large amount of water, and make to measure flow value through water meter, along with water level declines, water pressure also reduces gradually, when water level drops to piezoresistive pressure sensor 11 place water level, sensor again emissioning controling signal " 0 " is given electromagnetic pressure control valve door 9, thereby close water delivering orifice, now the flow of water is larger in drainpipe, and water meter can be measured its flow completely, adds the total amount that the water yield (drawing according to the height * water storage box floorage of water level) in water storage box 6 is underground closed drainage.Before device is used, in device, inject little water, make it be full of water meter to that section of drainpipe of water delivering orifice, external and internal pressure is equal to, and this section of water remains in pipe, thereby has solved the flow value that cannot measure this section of water.
The above is only the preferred embodiment of the present invention; be noted that for those skilled in the art; under the premise without departing from the principles of the invention; water meter and the power supply of different size can be installed according to actual conditions; regulate the type of pressure transducer and the setting height(from bottom) of pressure transducer; can also make some improvements and modifications, these improvements and modifications also should be considered as protection scope of the present invention.
