Drawings
Fig. 1 is a schematic structural diagram of the present invention.
Detailed Description
The embodiments of the present invention will be described in detail with reference to the accompanying drawings, and the embodiments are implemented on the premise of the technical solution of the present invention, and detailed implementation is given, but the scope of the present invention is not limited to the following embodiments.
As shown in figure 1, the gate vent with overhaul function of the utility model can be used in the design of a plug board valve type gate, such as a power station inlet quick door, a pumped storage tail water accident door and the like. Among the above-mentioned operating mode, gate 1 is installed in gate slot 2, and the top sealing connection of gate slot 2 has the frame 4 that is used for installing hydraulic hoist 3, and hydraulic hoist 3 is located installation cavity 5, and hydraulic hoist 3's hanging head links to each other with gate 1's lug, buries the steel pipe that has set up perpendicularly as access hole 6 underground in the breast wall concrete in gate 1 low reaches, and its aperture size is set for according to operating condition, should satisfy maintenance space requirement and air flow requirement simultaneously at least. The top (namely the first end) of the access hole 6 extends into the installation cavity 5 and is 300mm higher than the bottom surface of the installation cavity 5, a flange is welded on the access hole, and a sealing flange cover 7 connected by bolts is arranged on the flange under normal conditions and is used for plugging the access hole 6; when the maintenance is needed, the flange cover 7 is opened, so that the maintenance personnel can go in and out the maintenance hole 6. Furthermore, the top of the installation cavity 5 is provided with an overhaul hanging box 8 which is right opposite to the overhaul hole 6, so that the overhaul hanging box is convenient for the overhaul personnel to take when getting in and out. The bottom (i.e. the second end) of the access hole 6 extends to the top of the flow channel 9, so that the access hole 6 is communicated with the flow channel 9, and a maintainer can take the access hanging box 8 to reach the bottom of the flow channel 9 through the access hole 6 to carry out work. A vent hole 10 is also arranged on one side of the access hole 6, the vent hole 10 is a vertical steel pipe with an elbow at the bottom, and the tail end (namely, the third end) of the elbow is communicated with the side wall of the middle upper part of the access hole 6, so that the vent hole 10 is connected with the access hole 6 in a Bu-shaped external connection mode; the top end (i.e. the fourth end) of the vertical steel pipe of the vent hole 10 extends up to a position outside the dam body higher than the highest water level in front of the dam so as to ensure sufficient ventilation behind the down-the-hole gate. In order to prevent the top of the gate from forming vacuum when the gate 1 is closed quickly, an air supply branch pipe 11 extending into the gate slot 2 is also arranged at the upper part of the access hole 6.
It should be noted that in the description of the present invention, terms of orientation or positional relationship such as "front", "rear", "left", "right", "vertical", "horizontal", "inner", "outer", etc., are based on the orientation or positional relationship shown in the drawings, and are only for convenience of description and simplification of description, but do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus, should not be construed as limiting the present invention.
