Description
Technical field
The utility model is related to the power station technical field of water-control project and in particular to a kind of Hydropower Station radial door
Water seal compression adjusts special purpose device.
Background technology
Taking pavilion mouth water-control project as a example, its power station flood sluicing block arranges 8 hole open type surface spillways, and every hole sets
Put a fan extended-top type arch gate, table hole Segmental service gate port size 14.0 × 23.0m, elevation of weir crest 438.5m, bottom
Bank elevation 437.481m, Zhi Jiao center elevation 450.0m, cambered surface radius 29.0m, gate structure is designed as three girder allotment arm type
Formula.Since the lower lock retaining in 2013 of pavilion saliva power station, run actual according to live follow-up investigations power station surface spillway door
Situation, there is localized seepage's regimen condition in gate side sealing, and have the trend increasing year by year in various degree.Before gate flood in 2015
During maintenance, open liter gate to open position, check side sealing sealing situation, find " p " type side sealing rubber of leaking area
Linearity exists exceeded in various degree, simultaneously it was also found that gate side sealing seat board puller bolt m20 × 220mm has deformation, change
There is certain displacement change in shaped position side sealing sealing seat board.By analysis, floodgate side sealing water leakage is caused to increase
Reason is not enough mainly due to the surely tight bolt strength of side sealing, leads to bolt bending, during gate opening/closing, in gate slot
Under the extruding of siding track, local displacement in side sealing sealing seat board, leads to water seal decrement not reach design load, or even and siding track
Between sealing face, light-transmitting gap occurs, cause gate side sealing leak.Not ugly according to water seal mounting design profile above
Go out, former adjustment bolt is m20 × 220mm, gate side sealing pre compressed magnitude 5mm (design), and gate side sealing mounting and adjusting completes
Afterwards it is necessary to be welded and fixed m20 × 220 puller bolt respectively with side sealing bearing and side case nut.
Existing design structural disadvantages: after gate puts into operation, water seal carrying bolt m20 × 220 two ends are all welded
Be fixed on water seal seat board and side box beam, final bolt two ends be actually fixing welding it is impossible to be micro-adjusted.If fruit by
In needing to carry out micro adjustment it is necessary to have, then need to take carbon arc air gouging by the bolt solder joint being fixed on side sealing seat board
Exclude rear and possess fine setting condition, and execute-in-place narrow space it is impossible to thoroughly remove solder joint, simultaneously because gouge solder joint can not
Avoid causes permanent damage in itself to bolt, repeats to weld the intensity undoubtedly reducing metal after adjustment.Even if not considering
Previous reasons, but due to reasons such as the deformation of m20 × 220 adjustment bolt and corrosions, bolt can be caused cannot to adjust, can only remove
Side sealing seat board, just possesses replacing adjustment bolt condition, then is welded and fixed.Due to work on the spot position limitation, work difficult
Huge and loaded down with trivial details, and there is work high above the ground, potential safety hazard, above a variety of unfavorable factors, Jeakage through Sluice Sealant is run with sealing and daily
Operation maintenance is all totally unfavorable.
Utility model content

Specific embodiment
With reference to embodiment, the utility model is described in further detail, but embodiment of the present utility model is not
It is limited to this.
As shown in Figure 1 and Figure 2, Fig. 1 shows the Hydropower Station radial door pressure of water seal according to one embodiment of the utility model
The tight structural representation adjusting special purpose device, to schematic diagram, a kind of Hydropower Station radial door water seal compression is adjusted a for Fig. 1 for the Fig. 2
Special purpose device, including adjusting means bearing 1, locking nut 2 and bolt 3, described adjusting means bearing 1 bottom arranges a truncated cone-shaped
Hole 4, also set up in the middle part of described adjusting means bearing 1 one axially through screwed hole 5, described bolt 3 be arranged at described adjust dress
Put bearing 1 top and coordinate with described screwed hole 5, described locking nut 2 is arranged on described bolt 3, and described adjusting means is propped up
Seat 1 bottom is used for being weldingly fixed at the box beam nut of side, and described bolt 3 is used for withstanding on gate side sealing seat board.
Preferably, a diameter of 50 millimeters of the bottom side (on the left of truncated cone-shaped hole 4 as shown in Figure 1) in described truncated cone-shaped hole 4, described circle
A diameter of 40 millimeters of the upside (on the right side of truncated cone-shaped hole 4 as shown in Figure 1) in platform shape hole 4, the depth in described truncated cone-shaped hole 4 is 20 millis
Rice.
Preferably, model m20 of described screwed hole 5；Model m20 × 100 of described bolt 3.
The operation principle adjusting special purpose device to the Hydropower Station radial door water seal compression of above structure below is done further
Illustrate:
The utility model can adjust accordingly according to running needs, and can increase the strength and stiffness of adjustment bolt,
After machining bearing, rest base solid welding all around is scheduled on the side box beam nut position excised, all round closure welds,
Due to being not required to that the excision of m20 nut will be fixed on the box beam of former side, greatly reducing and former adjustment bolt and nut are cut polishing
Workload, passes through to adjust bearing (high 100mm) simultaneously, actually shortens adjustment bolt length (m20 × 100), bolt is long
The more former design of degree reduces 120mm, changes bolt strength simultaneously and is 8.8 grades, effectively raise adjustment bolt bending resistance and
Compression strength, mounting and adjusting bolt after bearing is installed, by design attitude adjustment side sealing one side decrement (5mm), and will
Locking nut is locked on adjusting apparatus bearing, forms a blocking mechanism, such gate all can be in side water in opening-closing process
Under envelope holding device effect, keep being in gate slot by design decrement, be effectively guaranteed the stagnant water effect of gate side sealing.
Being also advantageous in that of this equipment mechanism simultaneously, even if compression situation not in place in side sealing, can also be timely
Loosening locking nut after, adjust fastening screw (m20 × 100), compression side sealing to compression position, then locking nut, protect
Hold the normal sealing state of side sealing.The adjustment of this mechanism arrangement is flexible, and avoids former design adjusting apparatus and must use carbon
The defect that arc gouge can adjust after removing solder joint, after former design bolt length being reduced, equal in gate side sealing simultaneously
Lateral pressure under, improve bending strength than original structure.
It is found through experiments, after side sealing pressing regulation device of the present utility model, gate sealing effect obtains
Significantly improve, equipment is safe and reliable to operation, is that next step equipment operation maintenance normalization is had laid a good foundation.
