Description
Technical field
The utility model relates to a kind of water cap and application thereof, is specifically related to a kind of rubber dam and fills outfall water cap.
Background technology
Rubber dam has safety, economic, utilization a kind of low water head liquid-retaining structure flexibly, is widely used in hydraulic engineering construction.General employing water is that medium fills dam sack of rubber dam, dam bag base plate is provided with and fills outfall.During water-filling, high pressure water impact dam bag adhesive plaster, often can cause the adhesive plaster at filling opening place to break; Because current suction function dam bag adhesive plaster is by filling opening absorption blocking aperture during draining, dam Nei Shui can not discharge, and affects the dam flood passage that collapses.
Utility model content
The purpose of this utility model is to provide a kind of simple, reliable, and during for preventing dam bag water-filling, when high pressure water impact dam bag, dam bag draining, the suction function of current causes the water cap in bag adhesive plaster absorption blocking aperture, dam.
For achieving the above object, the technical scheme that adopts of the utility model is as follows:
A kind of water cap, it comprises support, at the bottom of the cap that is arranged at the cap of pedestal upper end and is arranged at pedestal lower end; Described support is hollow structure, and described support is provided with water stream channel; Be flange at the bottom of described cap, described flange is connected with the gutter road junction flange that fills filling drainage pipe by bolt.
Further, support described in the utility model is the hollow structure of at least two support floor compositions, and the space between described support floor is water stream channel; Or described support is the hollow structure of at least two water guide blade compositions, and the space between described water guide blade is water stream channel.
Further, the gross area of water stream channel described in the utility model is 1.2 ~ 1.5 times that fill drainage pipe cross section area of passage.
Further, cap described in the utility model is ball coronal structure.
Further, cap described in the utility model radius of spherical crown for described in fill 2 ~ 3 times of drainage pipe diameter.
Further, water cap described in the utility model height for described in fill 0.8 ~ 1.5 times of drainage pipe diameter.
Described water cap fills the application in draining at rubber dam.
The beneficial effect adopting technique scheme to produce is:
Water cap of the present utility model is used for rubber dam and fills draining, and when avoiding water-filling, current attack dam bag directly, prevents the generation in bag absorption aperture, dam during draining; The turnover stream condition that dam bag fills outfall can be improved, improve dam bag application life, obtain good economic benefit.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model water cap;
Fig. 2 is the using state figure of the utility model water cap;
In the drawings: 1, cap; 2, support; 2-1, water stream channel; 3, at the bottom of cap; 4, dam bag; 5, concrete floor; 6, drainage pipe is filled; 6-1, fill gutter road junction flange.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is further detailed.
As shown in accompanying drawing 1,2, water cap of the present utility model to have comprised at the bottom of the support 2 of water guiding action, the cap 1 being arranged at support 2 upper end and the cap being arranged at support 2 lower end 3.
Described support 2 is made up of at least 2 water guide blades or support floor, hollow structure, the space composition water stream channel 2-1 between water guide blade or support floor; When dam bag fills, current flow to water cap from filling drainage pipe 6, flow into dam bag uniformly and stably by the water stream channel 2-1 of water cap.During dam bag draining, dam water-in-bag fills drainage pipe 6 from water cap surrounding slowly through water stream channel 2-1 inflow and is discharged by water.
Water stream channel 2-1 can for multiple windows that the rack side wall of tubulose is offered, and now the resistance of current is comparatively large, and head loss is large; Water stream channel 2-1 can be the space between water guide blade or support floor, and now, the water guide of water stream channel 2-1 is effective, and head loss is little.Water guide blade or support floor are the hard material of the bending resistance after having enough high pressure resistant impacts and pressurized.The structure of the utility model water cap is simple, is beneficial to make and cost-saving.
At the bottom of described cap, 3 is flange, for being connected with the gutter road junction flange 6-1 that fills filled on gutter road junction 6, installs fixing water cap.
Described cap 1 forms for corrosion resistant plate forging and stamping, can prevent High-Pressure Water from directly impacting dam bag 4, cause dam bag tear failure during dam bag water-filling; Prevent because dam bag adhesive plaster is adsorbed in pipeline opening by suction function during draining, blocking water stream channel.
The water stream channel 2-1 gross area of water cap not strict restriction, as long as can meet the outflow of water and flow into.When the gross area of water stream channel 2-1 is 1.2 ~ 1.5 times of pipeline section area, current are unobstructed, without obvious turbulent phenomenon, are the preferred technical scheme of the utility model.
The shape size of cap 1 not strict restriction, as long as the ability of buckling distortion when can meet impact strength and negative-pressure adsorption effect.When the shape of cap 1 is spherical crown shape, and radius of spherical crown R is 2 ~ 3 times of described pipe diameter D, and when water cap height H is 0.8 ~ 1.5 times of described pipe diameter D, current are unobstructed, without obvious turbulent phenomenon, is the preferred technical scheme of the utility model.
At the bottom of cap 3 shape and the not strict restriction of structure, be fixed on fill on drainage pipe as long as water cap can be met.More preferably 3 flange at the bottom of cap gutter road junction 6 fill the flange that gutter road junction flange 6-1 is a secondary same specification with filling, by periphery erection bolt two panels flange twisted solid together.
Accompanying drawing 2 is using state figure of the present utility model, in use, dam bag 4 is fixed on the top of dam concrete base plate 5, be provided with in concrete floor 5 and fill drainage pipe 6 for the draining of dam bag 4 note, during use, flange 3 at the bottom of water cap of the present utility model is fixed on and fills on the flange 6-1 of gutter road junction and can realize.
Support of the present utility model and cap adopt corrosion resistant plate to make, and with 3 to be welded as a whole at the bottom of cap.Flange at the bottom of cap and the flange filled on gutter road junction, adopt bolt, nut to connect.
