The utility model solves this technical problem the technical scheme that is adopted: the supply and drain water system of cushion pool, comprise and be used for the aqueduct that the cushion pool with two Dao Ba upstreams is communicated with the riverbed in two Dao Ba downstreams, this aqueduct is embedded in the dam body inside on dam, two roads, its front end leads to the base plate place of the cushion pool of two Dao Ba upstreams, and the rear end leads to the riverbed in two Dao Ba downstreams; By-pass valve control is installed on this aqueduct and is used for ponding with cushion pool and drain into water plug in dam, the two roads underwater bed.
The utility model cuts down the consumption of energy according to following thinking: because aqueduct is embedded in the dam body inside on dam, two roads, its front end leads to the base plate place of the cushion pool of two Dao Ba upstreams, the rear end leads to the riverbed in two Dao Ba downstreams, therefore this aqueduct is inevitable does not pass through from the top on dam, two roads, as long as its water plug is given the energy that the ponding of per unit weight in the cushion pool can rise to dam, two roads level of tail water height at the bottom of the dam on dam, two roads, just be enough to make the ponding in the cushion pool to be drained, so just saved the energy consumption of water plug.In addition, by aqueduct being embedded in the dam body inside on dam, two roads, make it become permanent facility, thereby avoided the installation and the dismounting work that repeat, saved the time of installing and removing the facility that draws water, for more time has been striven in the maintenance of energy-disspating.
Preferred embodiment as such scheme, dam body inside on dam, two roads has pump house, be provided with water pump in this pump house, the input of this water pump and output respectively be embedded in dam, two roads dam body in drinking-water pipe link to each other with gutter, the front end of this drinking-water pipe leads to the base plate place of the cushion pool of two Dao Ba upstreams, the rear end of this gutter leads to the riverbed in two Dao Ba downstreams, also is separately installed with drinking-water pipe by-pass valve control and gutter by-pass valve control on above-mentioned drinking-water pipe and the gutter; Also be connected with between above-mentioned drinking-water pipe and the gutter and be used to make the reverse charging pipe that to walk around water pump between this drinking-water pipe and the gutter and be communicated with, reverse water-filling by-pass valve control is installed on this reverse charging pipe.For ease of the maintenance to each valve, above-mentioned drinking-water pipe by-pass valve control, gutter by-pass valve control and reverse water-filling by-pass valve control are preferably disposed in the pump house.
The course of work of the foregoing description is: during draining, by water pump with the riverbed of the water in the cushion pool from pre-buried drinking-water pipe and gutter suction two Dao Ba downstreams; During water-filling, switch off the pump and drinking-water pipe by-pass valve control and gutter by-pass valve control and open reverse water-filling by-pass valve control, make the cushion pool of two Dao Ba upstreams and the riverbed in two Dao Ba downstreams form linker by reverse charging pipe this moment, thereby the water that makes two Dao Ba downstreams is input in the cushion pool, finishes the water-filling of cushion pool.
As seen, the major advantage of the foregoing description has been to realize the draining of cushion pool and the integration of water-filling function.In conjunction with the argumentation of front and as can be known, during draining, because the lift of water pump reduces, so the energy consumption of water pump reduces.And during water-filling, because current do not pass through water pump, therefore can not produce any influence to water pump, simultaneously, owing to form linker by reverse charging pipe, drinking-water pipe and gutter between the cushion pool of two Dao Ba upstreams and the riverbed in two Dao Ba downstreams, the water level in the water level of cushion pool and two Dao Ba downstreams can autobalance, and this is that present water-filling mode is difficult to accomplish.In addition, also having of the foregoing description is convenient to advantage that supply and drain water system is safeguarded and overhauled.
The beneficial effects of the utility model are: energy consumption reduces; In permanent building, the change temporory structure is permanent facility with the piping erection of water delivery, has avoided the installation and the dismounting work that repeat, has saved the time of installing and removing the facility that draws water, for more time is striven in the maintenance of energy-disspating.
