Description

Semi-circular disjunctor gate
Technical field
The present invention relates to a kind of farmland water conservancy works and use gate, specifically, is a kind of semi-circular disjunctor gate.
Background technology
Hydraulic steel gate is widely used in hydraulic engineerings such as diversion, generating, flood control and agricultural irrigation, can realize common dash, water intaking function.In recent years, in some agricultural irrigation project, be strict with and get top layer warm water and be used for agricultural irrigation, improving crop yield, and common gate can't be realized this functional requirement.
Summary of the invention
The present invention aim to provide a kind of simple to operate, safe and reliable, can under different sink water level condition, only get the semi-circular disjunctor gate that top layer 2m warm water is used to irrigate.
In order to solve the problems of the technologies described above; The technical scheme that the present invention adopts is: a kind of semi-circular disjunctor gate; Comprise a body and embedded part, the door body comprises the semi-circular trashrack in top and the semi-circular gate in bottom that vertically is provided with of vertical setting, and the semi-circular trashrack in said top is connected with the semi-circular gate in bottom through high-strength bolt; The semi-circular trashrack in top is welded by grizzly bar and beam body; Semi-circular trashrack top is provided with the hanger that links to each other with headstock gear, and the face that the both sides side bar of semi-circular trashrack contacts with embedded part is provided with self-lubrication pad, and the semi-circular gate in said bottom comprises beam body, semicircle panel and prevents that the base plate that bottom water flows out from sealing the unbaffled cylindrical shell in back that is welded; On semi-circular gate both sides, said bottom side bar and bottom girder with on the face that embedded part contacts, be respectively arranged with the self-lubrication pad of double as sealing; The said embedded part that is arranged on the gate pier is the dull and stereotyped overall structure of straight wall formula, on embedded part, has a plurality of through holes from top to bottom.
Said embedded part is the dull and stereotyped whole stainless steel structure of straight wall formula, and through hole is 4, is respectively high hole, mesopore, low hole and bottom outlet in embedded part middle part and bottom, and the water-filling slotted eye contracts in the embedded part top has.
The grizzly bar of said semi-circular trashrack is vertically arranged.
The high 2-3 rice of said semi-circular trashrack.
The high 4-8 rice of said semi-circular gate.
Gate of the present invention had both satisfied under any water level condition only gets the warm water about the 2m of top layer, and can prevent that dirt from getting into intake structure and resulting in blockage.Except that can realizing normal dash, the function that discharges water, importantly can be implemented in different reservoir levels, water intaking top layer, storehouse warm water improves the function of agriculture crop yield.

The specific embodiment
Below in conjunction with the accompanying drawing and the specific embodiment the present invention is done further explain:
Like Fig. 1,2,3,7, shown in 8; Semi-circular disjunctor gate of the present invention; Comprise a body and embedded part 9, the door body comprises semi-circular trashrack 20 in the top of vertical setting and the semi-circular gate 30 in bottom that vertically is provided with, and the semi-circular trashrack 20 in said top is connected with the semi-circular gate 30 in bottom through high-strength bolt 4; The semi-circular trashrack 20 in top is welded by grizzly bar 2 and beam body 3; Semi-circular trashrack 20 tops are provided with the hanger 1 that links to each other with headstock gear, and the face that the both sides side bar 3 of semi-circular trashrack 20 contacts with embedded part is provided with self-lubrication pad 7, and the semi-circular gate 30 in said bottom comprises beam body 5, semicircle panel 6 and prevents that the base plate 10 that bottom water flows out from sealing the unbaffled cylindrical shell in back that is welded; On the semi-circular gate 30 both sides side bars 5 in said bottom and bottom girder with on the face that embedded part contacts, be respectively arranged with the self-lubrication pad 8 of double as sealing; The said embedded part 9 that is arranged on the gate pier 11 is the dull and stereotyped overall structure of straight wall formula, on embedded part 9, has a plurality of through holes from top to bottom.
Said embedded part 9 is the dull and stereotyped whole stainless steel structure of straight wall formula, and through hole is 4, is respectively high hole 12, mesopore 13, low hole 14 and bottom outlet 15 in embedded part 9 middle parts and bottom, and water-filling slotted eye 16 contracts in embedded part 9 tops have.
The grizzly bar 2 of said semi-circular trashrack 20 is vertically arranged.
Said semi-circular trashrack 20 high 2-3 rice.
Said semi-circular gate 30 high 4-8 rice.
Specifically semi-circular trashrack is bearing on the self-lubrication pad 7.Gate is bearing on the self-lubrication pad 8, and self-lubrication pad 8 is a U type structure, double as gate sealing.Embedded part 9 is embedded on the gate pier 11, and embedded part 9 is whole continuous structure, and embedded part 9 and gate pier 11 have high hole 12, mesopore 13, low hole 14 and 15 4 intakes of bottom outlet at the forward external surface.For reducing the gate counterweight, have the water-filling slotted eye 16 that contracts in the embedded part at the embedded part top.
Like Fig. 4, Fig. 5 and shown in Figure 6, the operating principle of semi-circular disjunctor gate of the present invention is: semi-circular disjunctor gate is connected with headstock gear on the framed bent post through hanger 1, under headstock gear is controlled, can on gate embedded part 9, make vertical displacement movement.Like Fig. 5, when normal pool level, gate drops to the water surface under headstock gear control; Under gate deadweight effect, submerged, the gate bottom is before arriving 12 bottoms, high hole, because the gate buoyancy effect; Gate descends slowly, the water-filling groove that contracts in the embedded part can be in gate water-filling, offset part gate buoyancy effect; Gate drops to the precalculated position, stops the headstock gear operation, and gate is suspended on 12 predeterminated positions of high hole; Open high hole 12 lower gates, water flows to downstream from getting into semi-circular gate inner chamber between the semi-circular trashrack grizzly bar through high hole 12.Semi-circular disjunctor gate then under water pressure and headstock gear effect, is fixed on the embedded part 9.When reservoir level reduces, during like Fig. 6, open headstock gear again; Gate continues to descend under the deadweight effect, strides across the precalculated position that high hole 12 arrives mesopore 13, stops the headstock gear operation; Gate is suspended on mesopore 13 predeterminated positions; Open mesopore 13 lower gates, water flows to downstream from getting into semi-circular gate inner chamber between the semi-circular trashrack grizzly bar through mesopore 13.Identically with last principle when water level reduces again operate operation.
When reservoir level raise, semi-circular disjunctor gate carried out reverse operating and gets final product.
Above-described embodiment only is used to explain technological thought of the present invention and characteristics; Its purpose is to make those skilled in the art can understand content of the present invention and implements according to this; Can not only limit claim of the present invention with present embodiment; Be equal variation or the modification that all disclosed spirit is done, still drop in the claim of the present invention.
