Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the present invention is further described.
As shown in Fig. 1 to Figure 10, blocking sluice gate of diversion tunnel detection system of the present invention, comprise intake tower 1, Diversion Tunnel 2 is provided with in intake tower 1, the hole import of intake tower Inner guide is provided with shutoff gate 3, is provided with between operation 4 in the intake tower above shutoff gate 3, also comprises detect aperture 5, the upper end of described detect aperture 54 to be communicated with between operation, and its lower end is communicated with the Diversion Tunnel in shutoff gate 3 downstream; The upper end of detect aperture 5 is provided with openable shutoff cover plate 6.Wherein, the effect of shutoff cover plate 6 is shutoff detect aperture 5, when when not needing to detect, by shutoff cover plate 6 by detect aperture 5 shutoff, for the ease of dismantling and guaranteeing plugging effect, generally shutoff cover plate 6 can be carried out connection by flange arrangement and bolt connecting mode.And when needs detect, only need shutoff cover plate 6 to open, then carry out detection to shutoff gate 3 rear, observation by detect aperture 5.
At least the following two kinds can be adopted in the present invention to detect view mode, and the first detects for transferring corresponding checkout equipment by detect aperture 5, carries out detecting, observing as can be transferred a camera by detect aperture 5; The second is that the rear of testing staff 12 to be transferred to shutoff gate 3 by detect aperture 5 carries out detecting, observing.Generally speaking, for the ease of detecting, observing and the suitable operation such as adjustment, maintenance, usually above-mentioned the second detection mode is adopted.
When above-mentioned employing the second detection mode, all conveniently can carry out to make testing staff 12 detecting, observing on the whole width of shutoff gate 3.General Requirements testing staff 12 can on the width of shutoff gate 3 shift position.The present invention adopts following structure for this reason: arrange an expansion platform 7, and between operation, 4 are positioned at directly over detect aperture 5 and are provided with suspension bracket 8, described expansion platform 7 by the liftable hanging of lifting rope 10 on suspension bracket 8; Described expansion platform 7 has receipts superimposition and launches two states, and when expansion platform 7 is for being freely elevated by detect aperture 5 when receiving overlapping state, when expansion platform 7 is deployed condition, the width launched after platform 7 expansion is corresponding with the width of Diversion Tunnel 2.By being set to structure that is stacked to be received and that launch by launching platform 7, while guarantee testing staff 12 conveniently detects the whole width of shutoff gate 3, the size of detect aperture 5 can be reduced, to guarantee the structural strength of intake tower so as far as possible.And on suspension bracket 8, being generally provided with an electric hoist or similar to lifting by crane the driving mechanism with below, one end of corresponding lifting rope 10 is connected with electric hoist.In addition, general, in order to make detect aperture 5 have stronger structural strength, simultaneously constructability again, avoiding carrying out punch operation to later stage intake tower, can be steel pipe 51 by the inner liner of described detect aperture 5; Namely when the construction of intake tower 1, a pre-buried steel pipe 51.
In addition, for the concrete structure launching platform 7, generally speaking, demand fulfillment is above-mentioned will go, namely while guarantee testing staff can detect the whole width of shutoff gate 3, reduce the size of detect aperture 5 as far as possible, namely reduce expansion platform 7 as far as possible and receive poststack area occupied on vertically.The invention provides following a kind of preferred structure: launch platform 7 and comprise halfpace 71, two side platforms 72 and bracing frame 73, described two side platforms 72 are hinged with the both sides of halfpace 71 respectively, the lower end of support frame as described above 73 is fixedly connected with halfpace 71, and bracing frame 73 is vertical with halfpace 71; Described lifting rope 10 is connected with the upper end of bracing frame 73; Also comprise two groups respectively with two side platforms 72 stay cord 74 one to one, one end of described stay cord 74 is connected with the upper end of bracing frame 73, and its other end is connected with the one end away from halfpace 71 on side platform 72.Like this, receive poststack at expansion platform 7, testing staff may stand in expansion platform 7 one lifting on halfpace 71, and after being launched by both sides platform, testing staff 12 can on the platform of side shift position, conveniently detect accordingly and observe.
In addition; safety when moving in detection platform to protect testing staff 12; the present invention is provided with fence 75 further on side platform 72; as shwon in Figures 5 and 6; and it is folded in order to make fence also can do corresponding receipts when launching platform and receiving folded thereupon; make to launch platform and integrally structure still compact, described fence 75 can be flattened and receive folded being connected with side platform 72.Can flatten as fence 75 and receive folded concrete structure, can refer to vibrational power flow shown in Fig. 5 and Fig. 7.
In addition, consider after expansion platform 7 launches, two ends on its width easily with Diversion Tunnel 2 avoid contact, in order to reduce the drag effects in above-mentioned contact process, the present invention is provided with roller 76 outwardly away from one end of halfpace 71 further on each side platform 72.So-called roller 76 outwardly, shown in composition graphs, refers to the wall of roller 76 towards Diversion Tunnel 2.In addition, when being provided with fence 75, except can the roller 76 be provided with in the one end away from halfpace 71 on each side platform 72 outwardly be, fence 75 be also provided with roller 76 outwardly away from one end of halfpace 71; Such setting also has a benefit, reference as shown in figure 5 and figure 7, in this case, when launching platform 7 and having receipts overlapping state phase demodulation state to carry out, side platform 72 is in the process launched to both sides, and the roller 76 meeting linear contact lay on fence 75 is to the wall of Diversion Tunnel 2, and, along with the further expansion of side platform 72, wall can act on certain power to the roller 76 on fence 75, orders about fence 75 and automatically launches from receipts overlapping state.
In addition, in the present invention, the receipts superimposition for side platform 72 launches operation, can adopt manual or automatically in theory, may also be and has testing staff 12 ACTIVE CONTROL, or undertaken controlling by all the other personnel.The present invention preferably adopts following structure: on bracing frame 73, arrange a hoisting mechanism 9 further, the rocking handle 92 that described hoisting mechanism 9 comprises reel 91 and reel 91 can be driven to rotate; The one ends wound that described stay cord 74 is connected with bracing frame 73 is on reel 91.Like this, testing staff only needs to rotate corresponding rocking handle 92, and the receipts superimposition that can be realized launching platform by the folding and unfolding of reel 91 pairs of stay cords 74 launches operation.Certainly, when carrying out folding and unfolding, testing staff should stand on halfpace 71, to guarantee its personal safety.
In addition, the present invention also can arrange stack 11, one end of described stack 11 is arranged on the upper end in detect aperture 5, and its other end passes rear and outside air environmental communication from the downstream of Diversion Tunnel 2.Such benefit is when being provided with detect aperture 5, and when carrying out Diversion Tunnel shutoff, the gas be convenient in the Diversion Tunnel between plugging construction section and shutoff gate 3 is discharged.
The present invention adopts above-mentioned blocking sluice gate of diversion tunnel detection system, when being detected by detection people 12 simultaneously, its concrete grammar is as follows: first, testing staff 12 transfers in the Diversion Tunnel in shutoff gate 3 downstream with receiving the expansion platform 7 of poststack by detect aperture 5, then launch platform 7, testing staff 12 is in the detection launching platform 7 to carry out to shutoff gate 3.And in the process detected, the height launching platform 7 can be controlled at any time, to detect differing heights position on shutoff gate 3.
