Abstract
The invention discloses a wall penetrating seal structure of an underwater rotating shaft of a steel dam gate. The wall penetrating seal structure comprises a wall penetrating steel structure and a seal chamber structure; the wall penetrating steel structure comprises an outer sleeve and a plurality of rib plates fixedly connected to the outer peripheral surface of the outer sleeve, inner sleeves are sheathed in the outer sleeve at intervals, an annular end plate is welded in a sealing way between the opening edges of each inner sleeve and the outer sleeve on the side of a river channel, an annular plate is welded in a sealing way between the other opening edge of each inner sleeve and the inner wall of the outer sleeve, and the other opening of the outer sleeve is provided with an annular seal chamber end plate; the seal chamber structure comprises a first seal ring welded on the annular plate, a seal slot and a seal ring arranged in the seal slot, and a second seal ring and a seal ring arranged in the second seal ring are at least arranged between the first seal ring and the annular seal chamber end plate; and the first seal ring and the second seal ring are connected to form a whole body through a cover plate. The wall penetrating seal structure of the underwater rotating shaft of the steel dam gate is designed for overcoming the defect of water seepage of a gate chamber caused by deformation easily generated because a rotating shaft of a bottom shaft driven flap gate is affected by factors such as external force, self-weight and differential settlement of underwater foundations.
Description
Technical field
The present invention relates to lower shaft and drive turnover board type gate, especially relate to turning cylinder sealing to through the wall structure under steel dam water seal.
Background technology
It is the Novel gate that one can realize functions such as " two-way water blockings, gatage is adjustable " that lower shaft drives flap gate (steel dam lock).Lock gate leaf adopts longitudinal cantilever beam structures, by the rotation of hydraulic switch machine operation lower shaft, gate flap setting dash or level is droped to the ground, and reaches the object of dash or sluicing.This type have aperture width large, can adjust gate flap angle according to water level and form manmade landscape, artificial landscape's waterfall, non-dash situation and crouch in the advantage such as good concealment, gate dam type under water, be usually used in flood control, gear tide, regulate the engineerings such as water level, comprehensive water transfer and civic landscape.Lower shaft drives flap gate as shown in Figure 1, is mainly made up of lock gate leaf 1, turning cylinder 2, turning cylinder bearing 3, wall-punching equipment, hydraulic hoist 4 etc.Because lock gate leaf 1, turning cylinder 2, turning cylinder bearing 3 etc. are installed under water, hydraulic hoist 4 is arranged in lock chamber 5.Therefore, turning cylinder 2 must be connected with hydraulic hoist 4 through after lock chamber 5 walls.Lock chamber side, should be without any phenomenon of leaking, seep water, to ensure the waterproof of hydraulic switch electromechanical equipment, moistureproof requirement after lower shaft is through walls.But because gate span is large, respective drive power is large, lower shaft diameter is large, and lower shaft is turning cylinder, affected by the factors such as external force, deadweight, underwater foundation differential settlement generation is out of shape.How to adapt to above unfavorable factor, turning cylinder sealing to through the wall structure becomes one of key technology of this gate under water.
Summary of the invention
The object of the invention be to provide a kind of good sealing effect, simple in structure, be convenient to regular maintenance and change turning cylinder sealing to through the wall structure under the steel dam water seal of seal.
For achieving the above object, the present invention takes following technical proposals:
Turning cylinder sealing to through the wall structure under steel dam water seal of the present invention, comprises steel work through walls and gas-tight silo structure; Described steel work through walls comprises: outer sleeve, uniformly be connected on described outer sleeve outer peripheral face, for multiple gussets of lock chamber wall inner concrete reinforcing bar welding, in outer sleeve, spacer sleeve is equipped with the inner sleeve passing through for described turning cylinder under water, between the inner and outer sleeves opening's edge in river course side, seal weld is connected to annular endplate, seal welding [Dan between another opening's edge of inner sleeve and outer sleeve inner tube wall, is provided with ring packing storehouse end plate at another nozzle of outer sleeve; Described gas-tight silo structure comprises: be welded on the first joint ring on described ring flat-plate, inner ring surface at described the first joint ring offers seal groove, sealing ring is placed in described seal groove, is at least provided with the second joint ring and is placed in the sealing ring in its inner ring surface seal groove between the first joint ring and described ring packing storehouse end plate; First, second joint ring is connected as a single entity by cover plate ring and bolt.
The sealing ring being arranged in described first, second joint ring inner ring surface seal groove is V-type, Y type or lip-type packing.
Advantage of the present invention drives the turning cylinder of flap gate affected by the factors such as external force, deadweight, underwater foundation differential settlement with regard to being for lower shaft, easily produces distortion and causes the deficiency seeping water lock chamber in and design.Steel work through walls is the fastening devices of gas-tight silo, is again the intensive aspect of position through walls wall, and the reinforcing bar when gusset of outer sleeve outer peripheral face is constructed and in body of wall is integrally welded, has ensured that steel work through walls fixedly positioning in body of wall.First, second joint ring is connected as a single entity by bolt and cover plate ring, like this, in the time that needs are changed sealing ring, can take off easily ring packing storehouse end plate and carry out, and makes line service more convenient; Meanwhile, according to importance of the degree of depth, equipment under water etc., multiple-sealed ring can be set flexibly and easily further to improve sealing effectiveness.

Fig. 2 is the A portion structure enlarged diagram of Fig. 1.
Fig. 3 is the B portion structure enlarged diagram of Fig. 2.
Detailed description of the invention
As shown in Figure 1, 2, 3, turning cylinder sealing to through the wall structure under steel dam water seal of the present invention, comprises steel work through walls and gas-tight silo structure; Described steel work through walls comprises: outer sleeve 6, uniformly be connected on described outer sleeve 6 outer peripheral faces, for multiple gussets 7 of lock chamber 5 wall inner concrete reinforcing bars welding, the inner sleeve 8 passing through for described turning cylinder under water 2 is housed at the interior spacer sleeve of outer sleeve 6, the internal diameter of inner sleeve 8 is determined according to the diameter of turning cylinder 2, between turning cylinder 2 and inner sleeve 8, should have certain interval, while there is maximum distortion to adapt to turning cylinder 2 in rotation process and inner sleeve do not produce the phenomenons such as friction, jam; Between inner and outer sleeves 8,6 opening's edges in river course side, seal weld is connected to annular endplate 9, and seal welding [Dan 10 between inner sleeve 8 another opening's edges and outer sleeve 6 inner tube walls is provided with ring packing storehouse end plate 11 at outer sleeve 6 another nozzles; Described gas-tight silo structure comprises: be welded on the first joint ring 12 on described ring flat-plate 10, offer seal groove and put sealing ring in the inner at the inner ring surface of described the first joint ring 12, between the first joint ring 12 and described ring packing storehouse end plate 11, be provided with the second joint ring 13 and be placed in the sealing ring in its inner ring surface seal groove, first, second joint ring 12,13 is connected as a single entity by cover plate ring 14 and bolt 15.As required, the sealing ring being arranged in first, second joint ring 12,13 inner ring surface seal grooves can be selected V-type, Y type or lip-type packing.
