For realizing above-mentioned utility model object, the technical solution adopted in the utility model is: provide a kind of and renovate gate for water conservancy diversion hole, shutoff power station, it is characterized in that, described gate of renovating comprises gate flap, gate flap side coordinates the keying forming gate flap with gate seat by hinge, the periphery of gate flap coordinates with gate seat and forms hermetically-sealed construction, seal is provided with between gate flap and the fitting face of gate seat, the top of gate seat is provided with hoisting equipment, hoisting equipment is arranged on bracing frame, and hoisting equipment is connected with gate flap by wire rope, assembly pulley.
Wherein preferred technical scheme is that upper side frame or the lower frame of described gate flap and gate seat are connected through the hinge.
Preferred technical scheme is that the angle of described gate seat stile and horizontal plane is 60 ° ~ 80 °, and gate seat makes hollow structure doorframe by i iron and/or channel-section steel further.
Preferred technical scheme also has, and described gate flap comprises the hollow structure door of frame, skeleton and door-plate composition, and door-plate is equipped with the movable pulley in assembly pulley.
Preferred technical scheme also has, the triangular support structure that support frame as described above is made up of semi girder and inclined shore.
Advantage of the present utility model and beneficial effect be, this be used for water conservancy diversion hole, shutoff power station renovate gate pound the door with existing flat board compared with tool have the following advantages:
1, without the need to building Diversion Tunnel intake tower, headstock gear is installed; Need gesture to build mounting platform above Diversion Tunnel near the mountain during headstock gear, the mode opening and closing support is installed.
2, without the need to gate slot, gate slot concreting 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 gate seat weight: 5015Kg; Open and close weight support frame: 6213Kg; Gross weight and bulkhgead gate are compared with gate slot and are only accounted for 22%.Much smaller than the weight adopting plane gate and gate slot shutoff, greatly save material.
When 4, adopting lifting jack to open and close, economy also can improve significantly.
