Abstract
The utility model relates to a water draining opening sealing and plugging device for a drainage system of a hydropower station. A transverse support frame is connected with a longitudinal support frame, an air bag is arranged on the transverse support frame, an air guide pipe passes through the longitudinal support frame and the transverse support frame to be communicated with the air bag, a load bearing plate is also arranged on the longitudinal support frame, and a plurality of cameras are also arranged around the air bag. The water draining opening sealing and plugging device for the drainage system of the hydropower station provided by the utility model has the advantages that the air bag is arranged on the support frame, so the underwater water draining opening sealing and plugging construction can be carried out on the shore, the sealing and plugging operation time is shortened, the underwater sealing and plugging risk is reduced, the personnel safety is guaranteed, and the sealing and plugging tightness is ensured.
Description
Technical field
The utility model relates to a kind of plugging device, particularly a kind of power station drainage system outfall plugging device.
Background technology
In existing power station the technical water supply equipment that much carries out the secondary cooling for equipment is arranged, technical water supply equipment drainage outlet generally can be below the lower storage basin water level, the relative tailwater elevation of layout of some technical water supply equipment is lower simultaneously, in case technical water supply draining service valve breaks down when needing repairing, need that then outfall is carried out shutoff and just can carry out the maintenance of draining valve, and to the technical water supply outfall below the water surface, its shutoff is generally finished by the diver, but then belong to breakneck work in the diving operation of downstream, power station, careless slightlyly then can cause life danger the diver.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of power station drainage system outfall plugging device, can carry out the outfall shutoff on the coast, shortens the shutoff time, support personnel's safety.
For solving the problems of the technologies described above, the technical scheme that the utility model adopted is: a kind of power station drainage system outfall plugging device, horizontal support is connected with longitudinal carrier, and air bag is installed on the horizontal support, and wireway passes longitudinal carrier and horizontal support is communicated with air bag.
Bearing plate also is installed on the described longitudinal carrier.
Also be provided with a plurality of cameras around the described air bag.
A kind of power station drainage system outfall plugging device that the utility model provides by air bag is set on support, is constructed thereby can carry out undersurface outfall shutoff on the coast, shorten the shutoff operating time, reduce shutoff risk under water, support personnel's safety guarantees that shutoff is tight.
Description of drawings
The utility model is described in further detail below in conjunction with drawings and Examples.
Fig. 1 is an overall structure lateral view of the present utility model.
Fig. 2 is an overall structure front view of the present utility model.
The specific embodiment
In Fig. 1, a kind of power station drainage system outfall plugging device, horizontal support 6 is connected with longitudinal carrier 3, and air bag 5 is installed on the horizontal support 6, and wireway 2 passes longitudinal carrier 3 and horizontal support 6 is communicated with air bag 5.On the described longitudinal carrier 3 bearing plate 4 is installed also.Also be provided with a plurality of cameras 7 around the described air bag 5.
When outfall needs shutoff, the longitudinal carrier 3 and the horizontal support 6 of band camera 7 are dived under water by the lifting of tail water door machine, the air bag 5 of horizontal support 6 and not ventilation is filled in the gutter of outfall 1 under the monitoring of camera 7, make bearing plate 4 be close to outfall 1, again by wireway 2 to air bag 5 inflation, allow air bag 5 expand and be close to tube wall, treat that air bag 5 has airtight wireway 2 behind the certain pressure, air bag 5 is keep-uped pressure, and this moment, air bag 5 sealed shutoff with outfall 1 under gas pressure.Device longitudinal carrier 3 can be made and be close to vertical wall mounting, simultaneously air bag 5 and bearing plate 4 is installed on the horizontal support 6 that is attached thereto, and regulates up and down by electro-motor, is used for accurately finding accurately the blocking pipe center.
