The structure comprises a filter net head, anchor rings, an embedded pipe, a bulkhead gate valve, a service gate valve, an underport intake tower and an underport barrel section. The underport barrel section is located in the downstream of the underport intake tower, an underport bulkhead gate and an underport service gate are arranged in the underport intake tower, the embedded pipe is embedded in the underport intake tower and a partition of the underport barrel section, the filter net head is mounted at the end of the embedded pipe, the anchor rings are welded to a pipe body of the embedded pipe, the service gate valve is disposed in the middle of the pipe body of the embedded pipe, and the service gate valve is disposed at the tail of the embedded pipe. A drain pipe is embedded in the underport intake tower and the partition of the underport barrel section, so that discharged small water flow is led into an underport barrel to be discharged into the lower reach, and the purpose of discharge is achieved. The structure has the advantages of being lowered in engineering investment, effectively adaptable to different water level amplitudes during operation, flexible in operation, low in post operation and maintenance cost and the like.
Description
Technical field
The utility model relates to a kind of structure of the low discharge current of releasing, and belongs to Hydraulic and Hydro-Power Engineering applied technical field.
Background technology
Hydroelectric generation is that the drop of the natural current of focus utilization generates electricity, and is clean energy resource green, environmental protection.First develop hydroelectric generation and be also the major action of advocating low-carbon economy society, energy-saving and emission-reduction, preserving the ecological environment.But hydroelectric project dam (lock) construction period and runtime, because dam (lock) intercepts river and runtime power station scheduling needs, easily cause dam (lock) to locate to section, power plant building, to occur subtracting (taking off) water, cause downstream river course cutout, riverbed is withered, irrigation water of downstream Lu Sheng aquatile, living water, agricultural production etc. is caused and had a strong impact on, the ecological environment in river has been caused to destruction.Along with the enhancing of national environmental consciousness, to ecological environment problem degree of concern pay attention to day by day, require, when building power station, take into account economic results in society and can preserve the ecological environment, promote the synchronized development of local industrial or agricultural.In conjunction with Present Domestic construction of hydropower plant situation, at present main utilization arranges the way that ecological little unit or bottom outlet release and overcomes the above problems, but the shortcoming that all exists construction investment to increase considerably.
Utility model content
For above technological deficiency, the purpose of this utility model is to provide a kind of structure with the low discharge current of releasing that reduce construction investment, it combines with permanent bottom outlet intake tower structure, can effectively adapt to the advantages such as different ranges of stage, flexible operation, later stage operation expense are less while having the construction investment of reduction, operation.
To achieve these goals, the utility model is by the following technical solutions:
A kind of structure of the low discharge current of releasing, comprise filter screen head, anchor ring, built-in pipe, maintenance gate valve, work gate valve, bottom outlet intake tower, bottom outlet barrel section, described bottom outlet barrel section is positioned at the downstream of bottom outlet intake tower, in bottom outlet intake tower, be provided with bottom outlet Emergency Gate and bottom outlet Service gate, described built-in pipe is embedded in bottom outlet intake tower and bottom outlet barrel section partition wall, filter screen head is arranged on the termination of built-in pipe, and anchor ring is welded on built-in pipe pipe shaft, overhauls the afterbody that gate valve is arranged in built-in pipe pipe shaft middle part, the gate valve of working is arranged in built-in pipe.
Described anchor ring adopts reinforcement fabrication.
Compared with prior art, the beneficial effects of the utility model are:
The utility model is by pre-buried gutter in bottom outlet intake tower and bottom outlet barrel section partition wall, the low discharge current of releasing are introduced bottom outlet barrel and are entered lower reache, reach the object of releasing, it has can effectively adapt to the advantages such as different ranges of stage, flexible operation, later stage operation expense are less while reducing construction investment, operation.

The specific embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail:
As shown in Fig. 1～Fig. 6, the utility model is a kind of structure of the low discharge current of releasing, comprise filter screen head 1, anchor ring 2, built-in pipe 3, maintenance gate valve 4, work gate valve 5, bottom outlet intake tower 6, bottom outlet barrel section 9, described bottom outlet barrel section 9 is positioned at the downstream of bottom outlet intake tower 6, in bottom outlet intake tower 6, be provided with bottom outlet Emergency Gate 7 and bottom outlet Service gate 8, described built-in pipe 3 is embedded in bottom outlet intake tower 6 and bottom outlet barrel section 9 partition walls, filter screen head 1 is arranged on the termination of built-in pipe 3, anchor ring 2 is welded on built-in pipe 3 pipe shafts, maintenance gate valve 4 is arranged in built-in pipe 3 pipe shaft middle parts, work gate valve 5 is arranged in the afterbody of built-in pipe 3.
Described anchor ring 2 adopts reinforcement fabrication.
When bottom outlet intake tower 6 is built to built-in pipe 3 elevation, carry out built-in pipe 3 pre-buried, for preventing pipeline silting, in built-in pipe 3 terminations, filter screen head 1 is set, stable during for the operation of assurance built-in pipe, at built-in pipe 3 pipe shafts, be welded with anchor ring 2, maintenance gate valve 4 is arranged in built-in pipe 3 pipe shaft middle parts, work gate valve 5 is arranged in built-in pipe 3 afterbodys, when bottom outlet barrel section 9 is poured into 3 pre-buried elevation, completes the installation of 3 burying work beforehands and work gate valve 5.When bottom outlet Emergency Gate 7 and Service gate 8 are during all in closed condition, can be by this structure low discharge current of releasing.
