Abstract
The utility model relates to a kind of novel sand discharge apparatus, comprise cylindrical gate pier column, in the below of gate pier column, gate pier is installed, described gate pier column offers floodwater releasing port along direction of axis line, flashboard is connected with by connecting rod in described floodwater releasing port, in the both sides of flashboard, wheel shaft is installed, the relevant position of gate pier column is provided with the chute tilted rearwardly and upwardly matched, flashboard is provided with the sealing plate that can seal chute, in the below of flashboard, screen pack is installed, be provided with contiguous block at the two ends of screen pack, contiguous block is arranged on gate pier column.The utility model structure is simple, reasonable in design, can either automatic water-storage, ensure the ordinary water level of reservoir, and can not timing sand discharge, avoid storehouse head Sediment Siltation, retaining is combined with sand discharge, can obtain comparatively ideal board thus make the storage capacity that reservoir keeps certain for a long time.
Description
Technical field
The utility model relates to field, power station, particularly relates to a kind of novel sand discharge apparatus for intake of hydropower station place.
Background technology
Power station is the integration engineering facility that water can be converted to electric energy, generally comprises the reservoir and Diversion system of hydropower station, power plant building, electromechanical equipment etc. that are formed by dash, outlet structure escape works.The high water level water of reservoir flows into factory building promotion turbine-generator units through diversion system and sends electric energy, then through step-up transformer, switching station and transmission line of electricity input electrical network.On heavily silt-carrying river, no matter be high head water power plant, or low water head river channel hinge, the water intaking sand discharge of powerplant intakes is always very important problem.For low water head river channel hinge, one sand surfing groove (sand trap) is set usually before powerplant intakes, and carries out drawing sand with bottom hole for sand flushing (scouring sluice).Owing to being subject to the restriction of sand surfing water diversion flow, erosion funnel scope is little, is difficult to reach desirable sand-flash effect.
Utility model content
The utility model, in order to overcome deficiency of the prior art, provides a kind of novel sand discharge apparatus, can not timing sand discharge, avoids storehouse head Sediment Siltation.
The utility model is achieved through the following technical solutions:
A kind of novel sand discharge apparatus, comprise cylindrical gate pier column, in the below of gate pier column, gate pier is installed, described gate pier column offers floodwater releasing port along direction of axis line, flashboard is connected with by connecting rod in described floodwater releasing port, in the both sides of flashboard, wheel shaft is installed, the relevant position of gate pier column is provided with the chute tilted rearwardly and upwardly matched, flashboard is provided with the sealing plate that can seal chute, in the below of flashboard, screen pack is installed, be provided with contiguous block at the two ends of screen pack, contiguous block is arranged on gate pier column.
As optimal technical scheme of the present utility model, described gate pier column is provided with mounting groove.
As optimal technical scheme of the present utility model, the cross section of described floodwater releasing port is trapezoidal, up big and down small.
As optimal technical scheme of the present utility model, described connecting rod is connected on gate pier column.
Compared with prior art, the beneficial effects of the utility model are: the utility model structure is simple, reasonable in design, can either automatic water-storage, ensure the ordinary water level of reservoir, and can not timing sand discharge, avoid storehouse head Sediment Siltation, retaining is combined with sand discharge, can obtain comparatively ideal board thus make the storage capacity that reservoir keeps certain for a long time.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure: 1-gate pier column; 2-gate pier; 3-floodwater releasing port; 4-flashboard; 5-wheel shaft; 6-chute; 7-connecting rod; 8-sealing plate; 9-mounting groove; 10-screen pack; 11-contiguous block.
Detailed description of the invention
In order to make the purpose of this utility model, technical scheme and advantage clearly understand, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the utility model, and be not used in restriction the utility model.
Refer to Fig. 1, Fig. 1 is structural representation of the present utility model.
The novel sand discharge apparatus of described one, comprise cylindrical gate pier column 1, in the below of gate pier column 1, gate pier 2 is installed, described gate pier column 1 offers floodwater releasing port 3 along direction of axis line, flashboard 4 is connected with by connecting rod 7 in described floodwater releasing port 3, described connecting rod 7 is connected on gate pier column 1, in the both sides of flashboard 4, wheel shaft 5 is installed, the relevant position of gate pier column 1 is provided with the chute 6 tilted rearwardly and upwardly matched, flashboard 4 is provided with the sealing plate 8 that can seal chute 6, in the below of flashboard 4, screen pack 10 is installed, at the two ends of screen pack 10, contiguous block 11 is installed, contiguous block 11 is arranged on gate pier column 1.Can either automatic water-storage, ensure the ordinary water level of reservoir, and can not timing sand discharge, avoid storehouse head Sediment Siltation, retaining is combined with sand discharge, thus makes the storage capacity that reservoir keeps certain for a long time.
Described gate pier column 1 is provided with mounting groove 9, and in the present embodiment, the cross section of described floodwater releasing port 3 is trapezoidal, up big and down small.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all do within spirit of the present utility model and principle any amendment, equivalent to replace and improvement etc., all should be included within protection domain of the present utility model.
