Abstract
The utility model relates to a gap water filling and horizontal pressing device for a navigation facility, which is arranged in a gap between a small working door and a horizontal door and comprises a gap water drain valve, a gap water drain pipe, an electric water drain valve, an electric butterfly valve, an upstream navigation channel water outlet and a manual water drain valve, wherein the gap water drain pipe is vertically arranged in the gap, namely the gap water drain pipe is arranged in parallel with the wall body of the upstream navigation channel, and the upstream navigation channel water outlet is vertical to and communicated with the gap water drain pipe. The problem of the work wicket appears the jam when descending because the unbalanced water pressure of both sides around the work wicket is solved, be applicable to the navigation facility of a kind that needs the flat pressure to open the gate.
Description
Technical Field
The utility model relates to a navigation facility, in particular to a navigation facility with two sides of a gate needing to be filled with horizontal pressure, and belongs to the technical field of design and manufacture of power station navigation facilities.
Background
The landscape flood hydropower station is designed to navigate through a dam building according to the standard of Lane cang river V-level channel and 300t ship type, and a position for constructing a 500t navigation building is reserved in a distant view. The navigation building is a hydraulic ship lift, adopts a wet transportation dam-passing and primary vertical lifting scheme, and has the maximum lifting height of 66.86 m. The navigation system mainly comprises an upstream mooring area, a floating navigation bank, a ship lift main body section and a downstream pilot channel.
The working small door at the head of the upper lock is arranged at the notch of the working large door in a concave shape, and is opened after the working large door is in butt joint with the ship receiving chamber, so that a water area channel for ships to enter and exit the ship chamber is formed, and the working small door is closed after the butt joint is removed, and water is retained together with the working large door. The hydraulic hoist of the small working door of the ship lift is a double-cylinder plunger hoist, and descends by means of the self weight of the body when descending. When the working wicket descends, due to unbalanced water pressure at the front side end and the rear side end of the working wicket and uneven friction force of a friction surface, the working wicket is easy to shut down in an out-of-tolerance mode, sometimes even falls rapidly to cause damage to an oil cylinder of the working wicket, hidden dangers are buried for safe and stable operation of equipment, and upstream butt joint time is prolonged.
SUMMERY OF THE UTILITY MODEL
In view of the above, in order to solve the problems in the prior art, the present invention provides a gap filling level pressure device for a navigation facility.
The technical scheme is as follows:
the utility model provides a navigation facility clearance fills water concora crush device, installs in the clearance between little door of work and the horizontal door, including clearance outlet valve, clearance outlet pipe, electric drain valve, electric butterfly valve, upper reaches navigation channel outlet, manual drain valve, wherein, the vertical arrangement of clearance outlet pipe is in above-mentioned clearance, and clearance outlet pipe and upper reaches navigation channel wall body parallel arrangement promptly, upper reaches navigation channel outlet with clearance outlet pipe is perpendicular and UNICOM.
The gap drain valve is arranged at the upper end of the gap drain pipe, and the electric butterfly valve is arranged at the lower end of the gap drain pipe.
And the electric drain valve and the manual drain valve are adjacently arranged on the water outlet of the upstream navigation channel.
The electric water discharge valve can adopt an electric ball valve or a butterfly valve.
Compared with the prior art, the utility model has the following beneficial effects:
according to the gap water filling and pressure equalizing device for the navigation facility, the electric butterfly valve is additionally arranged on the gap water drain pipe, so that the problem that the working small door is jammed when descending due to unbalanced water pressure on the front side and the rear side of the working small door is solved, and the gap water filling and pressure equalizing device is suitable for the navigation facility needing to open the gate by means of pressure equalizing.

Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, embodiments of the present invention will be further described with reference to the accompanying drawings.
Referring to fig. 1, the gap water filling and horizontal pressing device for the navigation facility is installed in a gap 1 between a small working door and a horizontal door, and comprises a gap drain valve 2, a gap drain pipe 3, an electric drain valve 4, an electric butterfly valve 5, an upstream navigation channel water outlet 7 and a manual drain valve 8, wherein the gap drain pipe 3 is vertically arranged in the gap, namely, the gap drain pipe 3 is arranged in parallel with an upstream navigation channel wall 6, the upstream navigation channel water outlet 7 is perpendicular to and communicated with the gap drain pipe 3, the gap drain valve 2 is installed at the upper end of the gap drain pipe 3, the electric butterfly valve 5 is installed at the lower end of the gap drain pipe 3, and the electric drain valve 4 and the manual drain valve 8 are installed on the upstream navigation channel water outlet 7 adjacently.
Referring to fig. 2, when the gap between the working doors needs to be filled with water, the electric butterfly valve 5 is closed, the gap water drain valve 2 is opened, the electric water drain valve 4 of the water outlet 7 of the upstream waterway is opened, the manual water drain valve 8 of the water outlet of the upstream waterway is a normally open valve, and water in the upstream waterway enters the gap water drain pipe 3 through the water outlet 7 of the upstream waterway by utilizing the principle of a communicating pipe and then is led to the gap between the working doors, so that the water filling of the gap between the working doors is realized. After filling the water level pressure, closing the electric drainage valve 4 of the water outlet 7 of the upstream approach channel.
Referring to fig. 3, when the gap drainage of the working wicket is needed, the electric drainage valve 4 of the drainage port 7 of the upstream approach channel is checked to be in the closed position, the electric butterfly valve 5 is manually opened, and then the gap drainage valve 2 is opened, so that the gap drainage of the working wicket can be realized.
The present invention is not limited to the specific details of the above-described embodiments, and various simple modifications may be made to the technical solution of the present invention within the technical idea of the present invention, and these simple modifications are within the protective scope of the present invention. The various features described in the foregoing detailed description may be combined in any suitable manner without departing from the scope of the utility model. The utility model is not described in detail in order to avoid unnecessary repetition.
