Description
Technical field
The present invention relates to Hydropower Project field, Hydraulic Metal, gate product unit, for the gate of power station diversion tunnel shutoff; What power station diversion tunnel plugging construction proposed a kind of renovates gate for water conservancy diversion hole, shutoff power station.
Background technology
At present in Hydropower Project diversion tunnel plugging construction, the gate used is commonly referred to as shutoff gate. The structure formation of gate is generally dull and stereotyped gate. Being arranged in inlet of diversion tunnel, after damming, gate is in opened condition always, and river waterflow is by diversion tunnel earial drainage; Engineering needs reservoir impoundment power generation latter stage, and shutoff gate falls closedown by supporting opening and closing mechanism, and reservoir starts retaining. Simultaneously for ensureing the safe operation of reservoir, diversion tunnel requires to carry out backfilling to block up in fact, and shutoff gate no longer works. Can raise with water level is submerged in the water of reservoir area, and the mission of shutoff gate terminates with regard to this.
Dull and stereotyped gate is arranged in the door groove of inlet of diversion tunnel, by the traction of opening and closing mechanism on diversion tunnel intake tower lifting, thus realizes the open and close of dull and stereotyped gate. When closing condition, the rubber water sealing of dull and stereotyped gate under the effect of water pressure and door groove Sealing Surface be adjacent to airtight, therefore realize water shutoff effect.
That is: dull and stereotyped gate itself can not water shutoff separately, in addition it is also necessary to supporting fabrication and installation door groove etc. This just dull and stereotyped gate as the shortcoming existing for shutoff gate. As shown in Figure 1, it is the structure of certain power plant project inlet of diversion tunnel 6x8-78m shutoff gate existing. Door leaf weight 66970Kg in the structure shown here; Door groove weight 39910Kg. Single with regard to cost of manufacture, door groove increases again by 60% weight.
Existing shutoff gate is the temporary facilities during Hydropower Project is constructed, and its outstanding feature is exactly ageing, economy.Dull and stereotyped gate uses as shutoff gate, itself does not possess independent water shutoff ability, in addition it is also necessary to fabrication and installation door groove etc. simultaneously. This just greatly strengthens construction cost, extends the duration of a project etc., and it is many unfavorable to bring.
Summary of the invention
The object of the invention is, overcomes defect of the prior art, it is provided that a kind of makes simple, easy for installation, simple operation, more economical and practical renovate gate for water conservancy diversion hole, shutoff power station.
For achieving the above object, the technical solution used in the present invention is: provides a kind of and renovates gate for water conservancy diversion hole, shutoff power station, it is characterized in that, described gate of renovating comprises Men Ye, door leaf side coordinates the keying forming door leaf by hinge with door seat, the periphery of door leaf coordinates formation sealed structure with door seat, it is provided with sealing member between Men Ye and the mating surface of door seat, the top of door seat is provided with hoisting equipment, hoisting equipment is arranged on bracing frame, and hoisting equipment is connected with door leaf by wireline, tackleblock.
Wherein preferred technical scheme is that upper side frame or the lower frame of described Men Yeyu door seat are connected through the hinge.
Preferred technical scheme is further, and the angle of the vertical limit of described door seat and horizontal plane is 60 �㡫80 ��, and door seat makes hollow structure doorframe by joist steel and/or channel-section steel.
Preferred technical scheme also has, and described Men Ye comprises the hollow structure door of frame, skeleton and door-plate composition, the travelling block being equipped with in tackleblock on door-plate.
Preferred technical scheme also has, the triangular support structure that support frame as described above is made up of socle girder and inclined shore.
Advantage and the useful effect of the present invention are that this gate tool compared with existing dull and stereotyped gate of renovating being used for water conservancy diversion hole, shutoff power station has the following advantages:
1, without the need to building diversion tunnel intake tower, keying machine is installed; Need gesture to build erecting stage above diversion tunnel near the mountain during keying machine, the mode opening and closing support is installed.
2, without the need to door groove, a groove concrete placement and the installation such as major and minor rail, end bank is decreased. Shorten installation period and construction cost.
3, prop up hole with the embodiment water conservancy diversion being below and renovate gate calculating: renovate lock gate leaf weight: 12371Kg; Renovate gate door seat weight: 5015Kg; Open and close weight support frame: 6213Kg; Gross weight and dull and stereotyped gate are compared with door groove and are only accounted for 22%. Much smaller than the weight adopting plane gate and door groove shutoff, greatly save material.
When 4, adopting lifting jack to open and close, economy also can improve significantly.

In the present invention, preferred embodiment also has, the triangular support structure that support frame as described above 6 is made up of socle girder and inclined shore.
Embodiment 1
This is used for the composition structure renovating gate at water conservancy diversion hole, shutoff power station, renovates gate primarily of door leaf 1, door seat 3, hinge 2, water seal arrangement four major part composition.
Door leaf 1 adopts overall steel structure welding: by panel, girder, forming every component such as beam, hinge ear plates, working face carries out necessary mechanical workout. It is connected with door seat by pivot shaft device, it is possible to realize opening closed rotation.
Door seat 3 is hollow square frame-shaped steel structure: be welded by steel plate, channel-section steel, joist steel etc., and combining site carries out necessary mechanical workout. Hinge seat board and door leaf hinge ear plate coordinates installs hinge, and the pressure-bearing block that surrounding distributes is for carrying effective compression in a leaf 1 water pressure, guarantee door leaf 1 water seal and door seat 3 sealing face and airtight, thus reaches the effect of water shutoff.
The installation mode renovating gate is as follows:
Can being arranged in diversion tunnel water-in by renovating gate, facade flows inclination 15��25 degree placement downstream. Door seat 3 welds and buries joint bar in advance and build second stage concrete and hole base concrete is fixed as one. The door leaf 1 renovating gate is arranged on a seat 3.
Difference according to hinge device present position, it is possible to be divided into two kinds of installation modes:
Hinge device, above hole, is called wall-hanging installation: the opening direction of gate is for upwards to turn over act, and when falling, door leaf 1 is buckled on a seat 3, because tilting certain angle, automatically closes under door leaf 1 gravity and effect of water pressure. Applicable discharge is stable, the short-term construction of non-flood period.
Hinge device, below hole, is called that horizontal is installed: flat the crouching on the horizontal plane support of hole of gate is opening-wide state, and closing direction is for upwards to lift. Applicable discharge changes greatly, construct across the long duration of non-flood period.
Renovate the keying of gate:
Small-sized gate of renovating can adopt simple lifting jack to open and close. Lifting seat is arranged on above diversion tunnel facade, is connected with the hanger renovated on gate by lifting jack, adopts manual operation or electronic realization to open and close.
Large-scale gate of renovating adopts the tractions such as windlass, tackleblock 8, wireline 7, is arranged in above diversion tunnel, it is possible to adopts support or along wall pulley guiding, draws the door leaf 1 renovating gate and rotate around hinge, it is achieved open and close.
The invention is not restricted to above-mentioned enforcement mode, those skilled in the art make to any apparent improvement of above-mentioned enforcement mode or change, all can not exceed the design of the present invention and the protection domain of claims.
