Technical field
The utility model relates to the technical field of dam sealing corollary apparatus, is a kind of dam bottom outlet bypass pipe water inlet ball sealer.
Background technology
As shown in Figure 2, the left side of dam 7 is the catchment, the right side is the district that discharges water, the inside of dam 7 is equipped with dam bottom outlet Emergency Gate 14, there is bottom outlet steel lining 13 on right side at dam bottom outlet Emergency Gate 14, the bypass pipe 8 that connected set pool and bottom outlet steel lining inside are arranged from left side to the bottom outlet steel lining 13 of dam 7, bypass pipe 8 on dam 7 right sides is installed with the bypass filling valve 11 of shutoff bypass pipe 8, bypass filling valve 11 places of bottom outlet steel lining 13 tops are installed with gallery 10, make bypass filling valve 11 in gallery 10 interior handled easily and maintenance.Must be to bottom outlet steel lining 13 interior water-fillings before opening dam bottom outlet Emergency Gate 14, water-filled bottom outlet steel lining 13 is interior to make dam bottom outlet Emergency Gate 14 left and right sides hydraulic balances, in order in hydrostatic, open or close dam bottom outlet Emergency Gate 14, open or closing presures thereby reduce dam bottom outlet Emergency Gate 14.The general bypass pipe 8 that passes through is to bottom outlet steel lining 13 interior water-fillings, but when winter temperature is crossed when low, gallery 10 is interior to be very easy to enter cold air, because bypass filling valve 11 is not done any Insulation in design, be easy to cause the 11 valve body bursting by freezing of bypass filling valve to leak, calculate by present storehouse water elevation, water level is higher than approximately 37 meters of bypass valve water inlet pipe mouths, as calculated, if under present flow action the valve body 3000m that will have an appointment that breaks fully
3The swelling of/h enters gallery 10, seriously jeopardize gallery 10 interior grouting personnel life securities, and cause the gallery 10 interior scopes of gallery 10 interior value more than 1,000 ten thousand not had by water logging, simultaneously also can cause huge obstacle for gallery 10 interior post-processed work, its loss is unpredictable, but bypass filling valve 11 is owing to being difficult for replacing with hydraulic pressure.
Summary of the invention
The utility model provides a kind of dam bottom outlet bypass pipe water inlet ball sealer, has overcome the deficiency of above-mentioned prior art, and it can effectively solve the damage of dam bottom outlet bypass filling valve and be difficult for the replacing problem.
The technical solution of the utility model realizes by following measures: a kind of dam bottom outlet bypass pipe water inlet ball sealer comprises ball; Surface at ball is fixed with hanger.
The below is the further optimization and/or improvements to above-mentioned utility model technical scheme:
The ball surface of the other end of above-mentioned corresponding hanger can be fixed with suspension ring, and the ball surface between hanger and the suspension ring is fixed with the layback ring.
The surface of above-mentioned ball can be fixed with one deck soft rubber.
Above-mentioned ball can be hollow steel ball.
The pressure that the utility model utilizes water dexterously with the shutoff of dam bottom outlet bypass pipe water inlet ball sealer on the bypass pipe water inlet, thereby replacing bypass filling valve that can be safely and fast, therefore not only greatly reduced the potential safety hazard of changing valve, avoid the generation of security incident, improved the operating efficiency of changing valve, the valve cost is changed in saving, has also avoided being worth in the gallery danger that up to ten million element devices incur loss.
Description of drawings
Accompanying drawing 1 is looked the half section structural representation for the master of the utility model embodiment 1.
Accompanying drawing 2 is use view of the present utility model.
Coding in the accompanying drawing is respectively: 1 is ball, and 2 is hanger, and 3 is suspension ring, and 4 is the layback ring, and 5 is soft rubber, 6 is the rope made of hemp, and 7 is dam, and 8 is bypass pipe, and 9 is dam facing, and 10 is gallery, 11 is the bypass filling valve, and 12 is wire rope, and 13 is the bottom outlet steel lining, and 14 is dam bottom outlet Emergency Gate.
The specific embodiment
Below in conjunction with embodiment and accompanying drawing the utility model is further described:
Embodiment 1, and as shown in Figure 1, this dam bottom outlet bypass pipe water inlet ball sealer comprises ball 1; Be fixed with hanger 2 on the surface of ball 1.
Can according to actual needs, above-mentioned dam bottom outlet bypass pipe water inlet ball sealer be made further optimization and/or improvements:
As shown in Figure 1, ball 1 surface of the other end of corresponding hanger 2 is fixed with suspension ring 3, and the ball surface between hanger 2 and the suspension ring 3 is fixed with layback ring 4.At suspension ring 3 counterweight is installed, what and weight of counterweight are determined according to the degree of depth of water and the speed of current.
As shown in Figure 1, the surface of ball 1 is fixed with one deck soft rubber 5.Soft rubber 5 mainly in order to strengthen sealing, can effectively be blocked the mouth of pipe, prevents the jetting that causes because of pressure reduction, makes that to change valve work in the gallery influenced.
As shown in Figure 1, ball 1 is hollow steel ball.
Above-mentioned dam bottom outlet bypass pipe water inlet ball sealer using method is carried out in the steps below: as shown in Figure 2, the first step, at first fixedly mount hoist engine at dam facing 9, hanger 2 on the ball 1 is fixedly connected with by wire rope 12 with hoist engine, close bypass filling valve 11, then transfer dam bottom outlet bypass pipe water inlet ball sealer and dam bottom outlet bypass pipe water inlet ball sealer is positioned at bottom outlet bypass pipe 8 water inlets in dam 7 left sides; Second step: in the gallery 10 on dam 7 right sides, build mounting platform, prepare new bypass filling valve 11; The 3rd step, open bypass filling valve 11, the strength by current is drawn onto dam bottom outlet bypass pipe water inlet ball sealer on bypass pipe 8 water inlets, because the pressure reduction of hydraulic pressure and air pressure makes dam bottom outlet bypass pipe water inlet ball sealer with in the bypass pipe 8 water inlet shutoff; The 4th step, when the water leakage at bypass filling valve 11 places obviously reduces, remove bad bypass filling valve 11, the bypass filling valve 11 that more renews, change complete after, new bypass filling valve 11 cut out and move dam bottom outlet bypass pipe water inlet ball sealer to dam facing 9 by hoist engine.
Can according to actual needs, above-mentioned using method be made further optimization and/or improvements:
As shown in Figure 2, transfer before the dam bottom outlet bypass pipe water inlet ball sealer, at the layback ring 4 fixed installation ropes made of hemp 6, after opening bypass filling valve 11, the rope made of hemp 6 enters bypass pipe 8 inside by the strength of current first, and the end of the rope made of hemp 6 flows out from the outlet of bypass pipe 8 along current, then dam bottom outlet bypass pipe water inlet ball sealer is drawn onto on bypass pipe 8 water inlets by the strength of current, in bypass pipe 8 water inlet shutoff, fix the rope made of hemp 6 ends or fixed weight this moment, makes dam bottom outlet bypass pipe water inlet ball sealer reliably with bypass pipe 8 water inlet shutoff.
As shown in Figure 2, in the first step operating personnel by Underwater Camera observation dam bottom outlet bypass pipe water inlet ball sealer and dam bottom outlet bypass pipe water inlet ball sealer is positioned at bottom outlet bypass pipe 8 water inlets in dam 7 left sides by Underwater Camera.
As shown in Figure 2, at wire rope 12 length mark is arranged, bottom outlet bypass pipe 8 water inlets that can substantially exactly dam bottom outlet bypass pipe water inlet ball sealer be transferred to dam 7 left sides according to absolute altitude and the length mark on the wire rope 12 of bottom outlet bypass pipe 8 water inlets.
As shown in Figure 2, be installed with balancing weight on the suspension ring 3.Can configure according to the depth of water balancing weight of Different Weight.
As shown in Figure 2, cause current to enter gallery 10 in order to prevent burst accident, the front waterwall that blocks in gallery 10 interior settings at least one of the first step.
