Abstract
The invention discloses a bottom gate of a reservoir, comprising a frame consisting of a base, a bracket and a top plate. The bottom gate of the reservoir further comprises a sealed tank, a gate body, a cable and a waterproof jacket, the gate body comprises a guide bar and a door panel for dividing water, the door panel is hinged to one end of the guide bar, a movable pulley is arranged at the other end of the guide bar, the cable is arranged on the top plate and penetrates out of the waterproof jacket at the top of the top plate after being wound on the movable pulley, the sealed tank for waterproof purpose surrounds outside the guide bar and the pulley, a guide sleeve is arranged between the guide bar and the sealed tank, a sealing ring is arranged inside the guide sleeve, the door panel is of a conical structure, a conical hole matched with the door panel is formed on the bottom plate, a conical rubber body is arranged on the conical surface of the door panel and a rubber layer matched with the conical rubber body is arranged at the conical hole. According to said technical scheme, the gate is closed based on the fluid mechanics without any driving force, and the gate has the advantages of small wear, long service life, a simple structure and convenient maintenance.
Description
Technical field
The present invention relates to a kind of water conservancy equipment, relate in particular to a kind of bottom of the reservior gate.
Background technology
Along with the construction of Hydraulic and Hydro-Power Engineering project, the water conservancy gate is indispensable equipment.Gate of the prior art is the starting and stopping type gate, when unlatching and closure, all needs power drive, and wearing and tearing are big, and the wearing and tearing meeting closure owing to gate after use a period of time is not tight, the generation slit, and water overflows.Gate closing force in closure is bigger, and is higher to each part requirement of gate, causes equipment huge, and complex structure brings difficulty to repair and maintenance.
Summary of the invention
Goal of the invention: the objective of the invention is to the deficiency to prior art, provide a kind of and when closure, do not need driving force, meet hydrodynamics, the little long service life of wearing and tearing, simple in structure, overhaul bottom of the reservior gate easily.
Technical scheme: in order to realize the foregoing invention purpose, the technical scheme that the present invention adopted is:
A kind of bottom of the reservior gate comprises the framework that base, support and top board constitute, and also comprises stuffing box, gate, hawser and waterproof jacket; Described gate comprises guide rod that is used to lead and the door-plate that is used for branch water, and described door-plate is hinged on the end of guide rod, and the other end of described guide rod is provided with movable pulley; Top board is provided with hawser, and described hawser is wrapped in movable pulley after be arranged on the waterproof jacket at top board top and pass, and the described stuffing box that is used for waterproof is enclosed in the outside of guide rod and pulley; Between guide rod and stuffing box, be provided with guide pin bushing; Be provided with sealing ring in the guide pin bushing inboard, described door-plate is conical, and described base plate is provided with the circular cone hole that cooperates with door-plate; The taper seat of described door-plate is provided with conical surface rubber bodies, and described circular cone hole is provided with the rubber layer that cooperates with conical surface rubber bodies.
The arranged outside of described support has filter screen.
Beneficial effect: the present invention compared with prior art, its beneficial effect is:
1, gate pressure through himself gravity and water in closure in bottom of the reservior descends, under the effect of guide rod and guide pin bushing, and free-falling; Conical door-plate cooperates with the circular cone hole, and closed door-plate under the effect of hydraulic pressure is realized water shutoff; Conical surface rubber bodies cooperates with the rubber layer in circular cone hole; Sealing effectiveness is better, has reduced the vibrations that closed door-plate makes generation, has effectively protected door-plate and circular cone hole;
2, door-plate and guide pillar are hinged, adjust angle automatically, and door-plate is engaged in the circular cone hole closely;
3, an end of guide pillar is provided with movable pulley, and lift gate under the effect of hawser has reduced 1/2 driving force, and structure is more reasonable;
4, the arranged outside of support has filter screen, prevents that foreign material from falling into the taper hole and influencing the gate sealing effectiveness.
Description of drawings
Fig. 1 is a structural representation of the present invention.
The specific embodiment
Below in conjunction with accompanying drawing, through a most preferred embodiment, technical scheme of the present invention is elaborated, but protection scope of the present invention is not limited to said embodiment.
As shown in Figure 1, a kind of bottom of the reservior gate comprises the framework that base 1, support 2 and top board 7 constitute; Also comprise stuffing box 3, gate 4, hawser 5 and waterproof jacket 6, described gate 4 comprises guide rod 41 that is used to lead and the door-plate 42 that is used for branch water, and described door-plate 42 is hinged on the end of guide rod 41; The other end of described guide rod is provided with movable pulley 43, and top board is provided with hawser 5, and described hawser is wrapped in movable pulley after be arranged on the waterproof jacket 6 at top board top and pass; The described stuffing box that is used for waterproof is enclosed in the outside of guide rod and pulley; Between guide rod and stuffing box, be provided with guide pin bushing 31, be provided with sealing ring 32 in the guide pin bushing inboard, described door-plate 42 is conical; Described base plate 1 is provided with the circular cone hole 11 that cooperates with door-plate; The taper seat of described door-plate is provided with conical surface rubber bodies 421, and described circular cone hole is provided with the rubber layer 111 that cooperates with conical surface rubber bodies, and the arranged outside of described support 2 has filter screen 21.
