Abstract
The utility model provides a pressure pro-pool deicing device which relates to a deicing device for the pressure pro-pool of a diversion type power station. The pressure pro-pool deicing device is arranged at the connecting point of a diversion channel and the pressure pro-pool, and is connected with the water inflow end of a pressure cover plate at the top part of a pressure conduit water inlet in the pressure pro-pool. The pressure pro-pool deicing device comprises a rise and fall component, a power component and a trash rack, is hinged at the end part of the water inflow end of the pressure cover plate through a deflector, and the other end of the deflector is connected with the rise and fall component and is hinged with the trash rack simultaneously. The pressure pro-pool deicing device can make ice bits brought by water flow in a flow passage enter a pressure conduit by following the water flow. The pressure pro-pool deicing device can adapt completely the water flow size in the flow passage. Ice blocks and floating sundries are discharged completely to the outer part of the flow passage, and the phenomena of accumulating and clogging are avoided.
Description
The utility model relates to a kind of deicer of run-of-river power station forebay.
The inventor is disclosed in 90225580.0 patents " the pressure cover panel assembly of the surface of open water deicing " in the patent No., its objective is that the ice slush that will bring with current in the runner and ice cube all introduce pressure pipeline by the pressure cover plate, thereby the accumulation and the clogging of ice slush and ice cube do not take place in forebay and runner.It is made up of the several sections pressure cover plates that are certain slope separately that are fixed in the forebay.Its weak point is to adapt to the variation that comes the discharge size in the runner, and after ice cube introduced pressure pipeline, to the water-guiding element generation jam and the clogging of hydraulic generator unit.
The purpose of this utility model is to avoid above-mentioned weak point of the prior art and provides a kind of ice bits (frost flower) that current in the runner are brought to bring pressure pipeline smoothly into current to generate electricity or drain into the runner outside, and the variation that can adapt to discharge size in the runner fully relies on self structure to drain into the runner outside fully ice cube and the floating foreign material that current bring, and do not pile up the deicer of the forebay that stops up in pressure pipeline water inlet and runner.
The purpose of this utility model can be by reaching with measure: the deicer of this forebay is installed in the junction of diversion runner and forebay, be connected with the pressure cover plate water intake end at pressure pipeline water inlet top in forebay, it comprises Lift Part, power part and trashrack, its special character is that it is hinged on pressure cover plate water intake end end by deflector, and the other end of deflector and Lift Part join and hinged trashrack of while.
The below of the trashrack of trashrack and deflector hinged place can be equiped with the power grid, and the power grid are made of the rotation grizzly bar of affixed several in rotating shaft and the rotating shaft and the interlaced arrangement of trashrack bar.
Trashrack can be that the trashrack grizzly bar by several mutual sockets constitutes, so that trashrack can be elongated or shortened as required.
The drawing of accompanying drawing is described as follows:
Fig. 1 is an embodiment of the present utility model: the structural representation of installing deicer in the run-of-river power station forebay.
Fig. 2 is another embodiment of the present utility model: the structural representation of only installing deflector and trashrack in forebay.
Below in conjunction with accompanying drawing the utility model is described in further detail:
As shown in Figure 1, in forebay (1), the hinged deflector in pressure cover plate (3) water intake end end (4) at pressure pipeline water inlet (2) top, the other end of deflector (4) and starting and stopping type Lift Part (5) join, and be hinged with trashrack (6) simultaneously, the other end of trashrack (6) extends to the bottom of runner (7), and can slide mobile in runner (7) bottom.Go up equipped with motive grid (9) at the trashrack (6) and the member (8) of the both sides, below of the trashrack (6) of deflector (4) hinged place, the rotating shaft (14) of power grid (9) is connected with the power part that is packed in its top (11) by driving member (10), driving member (10) can be a Worm and Worm Gear Driving, also belt transmission.
When coming water surface to bring ice bits and ice cube in the runner (7), with starting and stopping type Lift Part (5) with the water intake end Height Adjustment of deflector (4) to water surface elevation, at this moment, the ice in current bits pass trashrack (6) and introduce pressure pipeline water inlet (2) smoothly by deflector (4) and generate electricity.Ice cube in the current then rests on the water surface in trashrack (6) the place ahead, at this moment start power part (11), power part (11) drives the rotating shaft (14) of power grid (9) and rotating shaft (14) by driving member (10) and goes up the rotation grizzly bar (12) of affixed several and the interlaced arrangement of trashrack bar (6) and rotate, rotate grizzly bar (12) ice cube is brought to deflector (4) top, ice cube arrives runner (7) outside by the deadweight slip-stream then.When the hydraulic generator unit breaks down or need emergency shutdown; with Lift Part (5) deflector (4) water intake end Height Adjustment is arrived runner (7) bottom; meanwhile; slide forward the bottom of trashrack (6); make trashrack (6) be in runner (7) bottom with deflector (4), current in runner this moment (7) and ice bits ice cube are discharged runner (7) together smoothly.Do not have when freezing in summer, only need the water intake end of deflector (4) to be risen to the extreme higher position, make the hydraulic generator unit satisfy the needs that maximum is come discharge by Lift Part (5).
Shown in Figure 2, what be connected with deflector (4) is that assembly pulley Lift Part (5), power part (11) are manual hoist, trashrack (6) is that the trashrack grizzly bar by mutual socket constitutes, and the bottom-hinged of trashrack (6) is fixed on the member (13) of runner (7) bottom.
When the water surface in the runner (7) brings the ice bits with ice cube, shaking manual hoist (11) makes assembly pulley Lift Part (5) that deflector (4) and trashrack (6) are adjusted to height a little less than the water surface, the ice bits in the current passed trashrack (6) and introduced pressure pipeline water inlet (2) smoothly by deflector (4) and generate electricity this moment, and the ice cube in the current is then discharged outside the runner (7) or discharged after salvaging deflector (4) top by artificial through the end face of deflector (4) by the current at deflector (4) top.When the hydraulic generator unit hinders for some reason or need emergency shutdown; with Lift Part (5) deflector (4) water intake end is transferred to runner (7) bottom by its deadweight; each suit of grizzly bar of trashrack this moment (6) shortens same deflector (4) and is placed down in runner (7) bottom together; at this moment the current in the runner (7) and ice bits, ice cube and floating foreign material are all discharged runner (7) smoothly, thereby have avoided clogging.During summer, the water intake end of deflector (4) is risen to the extreme higher position, make hydrogenerator satisfy the needs that maximum is come discharge with Lift Part (5).
The utility model simple installation can be adapted to the variation that runner comes the discharge size, does not have the loss of row's ice stream amount, and can discharge all ice bits, ice cube and floating foreign material at any time, has ensured that the power station normally moves winter, has improved power station winter operation benefit greatly.
