Abstract

An arc gate for down-the-hole drainage channel comprises an arc gate body (6), a rotating supporter (7) connected with the arc gate body (6), a door device (8) provided on the arc gate body (6) to allow divers to enter and exit, and a compressing device (9) arranged outside the arc gate body (6) and provided inside with a compressing chamber (10). The door device (8) is covered by the compressing chamber (10). The compressing device (9) is also provided with a channel door device to allow divers to enter and exit. Drivers can go through the compressing device (9) and door device (8) into the outlet of a drainage channel, so as to shorten the access to the drainage channel outlet, reduce the time and facilitate the maintenance and leakage stopping operations. The utility model helps to increase the practical operation time of drivers in the drainage channel outlet, and thus to increase the efficiency of maintenance and leakage stopping operations.

Description

A kind of Segment gate of down-the-hole type drainage gallery

Technical field

The utility model relates to the improvement of drainage gallery port of export Segment gate such as deep hole in the reservoir key water control project, tunnel.

Background technology

The normal sluicing flow channels such as deep hole, tunnel that adopt are carried out flood discharge or emptying to its retaining in the key water control project of reservoir, and gate and opening and closing device thereof are the indispensable plant equipment of control drainage gallery.The application's described " down-the-hole type drainage gallery " is meant the drainage galleries such as deep hole, tunnel and emptying tunnel that are positioned under the reserve-water-level, the outlet of drainage gallery is generally rectangle or rectangle, outlet size has 6 * 7 meters, 7 * 9 meters, 9 * 9 meters not wait, even bigger.Figure 1 shows that down-the-hole type drainage gallery 1 that is arranged on the dam bottom and the schematic diagram that exports Segment gate 2 thereof.

Fig. 2 is the enlarged drawing that drainage gallery exports position and Segment gate 2 among Fig. 1, the structure of having showed existing Segment gate, and the outlet position of drainage gallery is provided with built-in fitting, lintel 3 as shown, siding track 4 and ground sill 5.The described Segment gate 2 of present specification does not contain and covers built-in fitting and opening and closing device, as Fig. 2, shown in Figure 3, described Segment gate 2 comprises Segment gate body 6 and the swing frame 7 that is connected with the Segment gate body, gate is along built-in fitting siding track 4 opening and closing of both sides, by the opening and closing device control and the realization (not shown opening and closing device) of its top, arrow has schematically illustrated the direction that Segment gate 2 is opened among Fig. 1.Existing Segment gate can satisfy cutting out and opening the drainage gallery outlet, but there is following deficiency: when needs export the position to drainage gallery, Segment gate inboard and both joints are safeguarded, during diving operations such as maintenance or leak stopping, the diving operation personnel can only enter into the outlet position via inboard aquifer of dam and drainage gallery, because Lu Jingchang, the hours underway that is used to enter and return consumes more, cause really being used for safeguarding, the actual job time of maintenance becomes seldom, and the diving operation official hour is quite limited each time, therefore, this exports the maintenance at position to profundal zone and the long drainage gallery of distance, diving operations such as maintenance or leak stopping bring very big difficulty and inconvenience, even the drainage gallery of shoaling layer also can influence diving operation efficient; Especially to the drainage gallery of profundal zone with long distance, diving operations such as maintenance, repair that its outlet position is needed or leak stopping, present reality is almost to become impossiblely, and because of can not effectively carrying out diving operations such as maintenance, repair or leak stopping, left hidden danger is difficult to eliminate.

Summary of the invention

The purpose of this utility model be propose a kind ofly to be convenient to keep in repair, the Segment gate of down-the-hole type drainage gallery that diving operation such as leak stopping and helping improves operating efficiency.

The technical solution of the utility model is referring to Fig. 3, with the background technology structure is that improve on the basis, this gate comprises Segment gate body 6 and the swing frame 7 that is connected with Segment gate body 6, improved structure is, the door gear 8 of coming in and going out for the diving operation personnel is set on Segment gate body 6, at Segment gate body 6 lateral surfaces (the no water surface when referring to the Segment gate duty) surge suppressor 9 is set, a concora crush chamber 10 is arranged in the described surge suppressor 9, door gear 8 is covered by concora crush chamber 10, also be provided with the access door device 11 of coming in and going out for the diving operation personnel on the surge suppressor 9,9 diving operation personnel of surge suppressor enter the transitional function in the drainage gallery outlet.The diving operation personnel can from the no water surface of the Segment gate body 6 in the dam outside via surge suppressor 9, door gear 8 directly enter in the drainage gallery outlet keep in repair, diving operation such as leak stopping.

Technique effect of the present utility model is, because Segment gate body 6 is provided with the door gear 8 and the surge suppressor 9 of coming in and going out for the diving operation personnel, the diving operation personnel can be from the no water surface of the Segment gate body 6 in the dam outside via surge suppressor 9, door gear 8 directly enters the maintenance of diving under water in the drainage gallery outlet, diving operations such as leak stopping, when fulfiling assignment or reach the time of return of reservation, return to the outside via door gear 8 and surge suppressor 9 equally, with the background technology ratio, shortened the path of the drainage gallery outlet of coming in and going out greatly and significantly reduced and entered in the drainage gallery outlet and by the required time of returning to external in the outlet, effectively increased the actual job time in the drainage gallery outlet, this exports the maintenance at position to profundal zone and the long drainage gallery of distance, diving operations such as maintenance or leak stopping have brought convenience, for the drainage gallery of shoaling layer, can improve diving operation efficient; Especially make diving operations such as the maintenance, repair at drainage gallery outlet position of profundal zone and long distance or leak stopping, by background technology hardly may and become and can realize, solved and failed the technical barrier that effectively solves for many years, obvious technical effects.

Below in conjunction with drawings and Examples the utility model is further specified.
