Abstract
The utility model relates to a new water in-taking pond for pumping station, comprising a soleplate, a pond wall and a pump and a water sucking flare opening which are arranged in the pond. The utility model is characterized in: the back wall of the water in-taking pond takes the shape of the letter of W; a water guide cone is arranged under the water sucking flare opening. The distance between the center of the water sucking flare opening and the back wall is 0.5 to 0.7 times larger than the diameter of the water sucking flare opening; the suspending height of the flare opening is 0.4 to 0.8 times of the diameter of the flare opening. An upwards raising soleplate with a raising angle of 4 degree is arranged at a place between the bottom of the flare opening and the back wall. The utility model is simple in structure and easy in production. The design of the W-shaped back wall avoids the low speed back-flowing areas on the side walls and compacts the back-flowing area behind the pipe on the water surface into a relatively small area. Due to the arrangement of a water cone under the flare opening, the singularities on the streamline are eliminated by the water guide cone. The two control parameters, i.e. the distance between the flare opening and the back wall and the suspending height of the flare opening are optimized, so that the vortex is avoided effectively and the loss of hydraulic power is small.
Description
Technical field
The utility model relates to the structure of pumping plant intake pool, belongs to the hydraulic engineering technical field.
Background technology
Intake pool (also claiming the open type intake pool) is the directly hydraulic structure of suction of supply-water pump suction water pipe, is made of base plate and pool wall, has table, is generally used for middle-size and small-size pumping plant, and the suction horn mouth of water pump suction pipe places the underwater of intake pool.Design under the improper situation at intake pool, intake pool easily produces vortex, influences unit efficiency even security of operation.Existing intake pool has multiple limit wall shape, have: rectangle, polygon, rear wall shape have semicircle, volute shape.But the intake pool of design is difficult to accomplish to prevent that the whirlpool band from producing at present, and hydraulic loss simultaneously is little again.So, the structure design of pumping plant intake pool, be a very important part of pumping plant global design, the little pumping plant intake pool of hydraulic loss that a no whirlpool of design-build band produces is that hydraulic engineering research, design and construction unit expect to solve and unsolved problem for a long time.
The utility model content
The purpose of this utility model is expected to solve unsolved problem for solving people exactly for a long time, provides a kind of and can prevent that the whirlpool band from producing, the again little novel pumping plant intake pool of hydraulic loss simultaneously.
The purpose of this utility model is to realize like this, novel pumping plant intake pool, comprise base plate, pool wall and be mounted on pump sump horn mouth in the pond, the rear wall that it is characterized in that intake pool is shaped as W shape, have water guide cone at the suction horn mouth, suction horn mouth center to the distance of rear wall is 0.5～0.7 times a suction horn mouth diameter, and suction horn mouth flying height is 0.4～0.8 times a suction horn mouth diameter.Described suction horn mouth bottom is provided with to the rear wall place and upwarps base plate, and it is 4 ° that base plate upwarps angle.
The utility model is simple in structure, produces and builds easily.Intake pool rear wall shape has adopted W shape, has eliminated the low speed recirculating zone of sidewall, and the recirculating zone behind the water surface place pipe is compressed in the less zone.The suction horn mouth is divided into water guide cone, and the streamline singular point of intake pool bottom is eliminated by water guide cone; The bell-mouthed rear wall distance that absorbs water and unsettled high two important controlling parameter can effectively prevent the generation of whirlpool band, and hydraulic loss reduce greatly with respect to traditional intake pool hydraulic loss through optimizing.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is a plane structure schematic diagram of the present utility model;
Among the figure: 1 rear wall, 2 upwarps base plate, 3 water guide cones, 4 suction water pipes, 5 suction horn mouths.
The specific embodiment
The rear wall 1 of intake pool adopts the W shape, on the base plate below the suction horn mouth 5 of water pump suction pipe 4 water guide cone 3 is set, upwarping base plate 2 by the setting of rear wall place, base plate upwarps 4 °, suction horn mouth 5 centers to the distance of rear wall 1 is that (rear wall is apart from 0.5～0.7D for 0.5～0.7 times suction horn mouth diameter, D is suction horn mouth diameter), suction horn mouth 5 flying heights are 0.4～0.8 times suction horn mouth diameter (unsettled high 0.4～0.8D, D is suction horn mouth diameter).
Claims (2)
1, a kind of novel pumping plant intake pool, comprise base plate, pool wall and be mounted on pump sump horn mouth in the pond, the rear wall that it is characterized in that intake pool is shaped as W shape, have water guide cone at the suction horn mouth, suction horn mouth center to the distance of rear wall is 0.5～0.7 times a suction horn mouth diameter, and suction horn mouth flying height is 0.4～0.8 times a suction horn mouth diameter.
2, novel pumping plant intake pool according to claim 1 is characterized in that described suction horn mouth bottom is provided with to the rear wall place to upwarp base plate that it is 4 ° that base plate upwarps angle.
