Abstract

The utility model discloses a kind of combined type water intake pumping station, comprise the channel be arranged on riverbed, described channel comprises open channel and closed conduit, described open channel is by the tapered configuration of water inlet end constriction gradually to water side, the water inlet end of described closed conduit is connected with the water side of described open channel, and the water side of described closed conduit is connected with a Round Sump pump house.The beneficial effects of the utility model are: open channel is set to front wide and rear narrow tapered configuration, can obtain the larger water yield, and the river course compliance lower for riverbed water level in dry season is stronger; The rear of channel adopts closed conduit, is conducive to the water inlet height controlling to enter Round Sump pump house, facilitates the setting of trashrack and the construction of Round Sump pump house; Round Sump pump house is down dug deeply, meet to strengthen the depth of water requirement of fetching water dry season.

Description

A kind of combined type water intake pumping station
Technical field
The utility model relates to pumping plant field, particularly a kind of combined type water intake pumping station.
Background technology
According to related specifications and engineering experience, in intake strucure water inlet, General Requirements is not less than the depth of water of 2.5 ~ 3.0m, can be reduced to 1.5 ~ 2.0m to the small-sized intake depth of water.By the restriction at water source, if need fetch water in the river of water depth deficiency 1.5m in dry season, generally can adopt the mode of building dam, by high for water level harmony with satisfied water intaking requirement.But if build fixed dam, though can raise dry season water level, meet requirement of fetching water dry season, also can raise flood level, what add Tai Ho Road both sides floods risk, and easily causes Sediment Siltation before dam simultaneously; If build movable dam, though can avoid Sediment Siltation before dam, what do not increase both sides, river course floods risk, and can meet requirement of fetching water dry season, and cost is higher.
Utility model content
The purpose of this utility model is deficiency and the defect of water-supply method in the river course for water depth deficiency 1.5m in existing dry season, a kind of combined type water intake pumping station is provided, this combined type water intake pumping station can meet requirement of fetching water dry season, and difficulty of construction is little, cost is low, can not adverse effect be caused to surrounding enviroment, can solve the problem.
The technical problem that the utility model solves can realize by the following technical solutions:
A kind of combined type water intake pumping station, comprise the channel be arranged on riverbed, it is characterized in that, described channel comprises open channel and closed conduit, described open channel is by the tapered configuration of water inlet end constriction gradually to water side, the water inlet end of described closed conduit is connected with the water side of described open channel, and the water side of described closed conduit is connected with a Round Sump pump house.
In a preferred embodiment of the present utility model, the water inlet end width of described open channel is 8 meters, and water side width is 4 meters; The whole process caliber of described closed conduit is 4 meters.
In a preferred embodiment of the present utility model, described Round Sump pump house comprises forebay, trashrack, clean hatch, collecting-tank successively along water (flow) direction, and the top of described collecting-tank is provided with equipment room and becomes power distribution station.
Owing to have employed technical scheme as above, the beneficial effects of the utility model are: open channel is set to front wide and rear narrow tapered configuration, can obtain the larger water yield, and the river course compliance lower for riverbed water level in dry season is stronger; The rear of channel adopts closed conduit, is conducive to the water inlet height controlling to enter Round Sump pump house, facilitates the setting of trashrack and the construction of Round Sump pump house; Round Sump pump house is down dug deeply, meet to strengthen the depth of water requirement of fetching water dry season.
Accompanying drawing explanation
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, be briefly described to the accompanying drawing used required in embodiment or description of the prior art below, apparently, accompanying drawing in the following describes is only embodiments more of the present utility model, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.
Fig. 1 is the top view of a kind of embodiment of the utility model.
Detailed description of the invention
The technological means realized to make the utility model, creation characteristic, reaching object and effect is easy to understand, below in conjunction with concrete diagram, setting forth the utility model further.
A kind of combined type water intake pumping station shown in Figure 1, comprise and be arranged on channel 200 on riverbed 100 and Round Sump pump house 300, channel 200 comprises open channel 210 and closed conduit 220, open channel 210 is by the tapered configuration of water inlet end 211 constriction gradually to water side 212, the water inlet end 221 of closed conduit 220 is connected with the water side 212 of open channel 210, and the water side 222 of closed conduit 220 is connected with Round Sump pump house 300.Water inlet end 211 width of the open channel 210 in the present embodiment is 8 meters, and water side 212 width is 4 meters; The whole process caliber of closed conduit 220 is 4 meters.
And the Round Sump pump house 300 in the present embodiment comprises forebay, trashrack, clean hatch, collecting-tank successively along water (flow) direction, the top of collecting-tank is provided with equipment room and becomes power distribution station, equipment room and become power distribution station on put and can prevent machinery equipment from making moist.Certainly, other the conventional Round Sump pump houses that easily can also expect for those skilled in the art of Round Sump pump house 300.Whole ingredient is built jointly in a building by Round Sump pump house 300, makes to arrange compacter, have occupation of land less, little, the convenient management of head loss.In order to strengthen the depth of water in dry season, increase water retention capacity of the present utility model, Round Sump pump house 300 down need be dug deeply, the concrete deep degree that down digs also needs according to landform and uses needs and determine.
Open channel 210 is set to front wide and rear narrow tapered configuration by the utility model, can obtain the larger water yield, and the river course compliance lower for riverbed water level in dry season is stronger; Moreover the rear of channel 200 adopts closed conduit 220, be conducive to the water inlet height controlling to enter Round Sump pump house 300, facilitate the setting of trashrack and the construction of Round Sump pump house 300.
More than show and describe general principle of the present utility model and principal character and advantage of the present utility model.The technician of the industry should understand; the utility model is not restricted to the described embodiments; what describe in above-described embodiment and manual just illustrates principle of the present utility model; under the prerequisite not departing from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall within the scope of claimed the utility model.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
