Abstract
The utility model relates to a rainwater drainage bucket, especially to a siphon rainwater bucket capable of preventing a whirlpool and mainly applied in a large-scale roofing rainwater drainage system. The siphon rainwater bucket comprises a fairing, a bucket base and a bucket body drainage tail pipe, wherein the main body structure of the bucket base comprises a funnel-shaped plate body. The center of the plate body is provided with a water outlet hole which is connected with the bucket body drainage tail pipe. The fairing comprises a top plate shaped like a round hat. The top plate is fixedly connected with the bucket base through a bolt. A plurality of diversion blades arranged in a radiation way are disposed on the upper surface of the fairing top plate along the center of the circle. And a plurality of water outlets are provided on the periphery of the top plate and corresponding to the diversion blades. A plurality of pieces uniformly arranged along the circumference for whirlpool prevention are equipped between the top plate and the bucket base. And the plurality of whirlpool preventing pieces, together with the bucket base disk body and the top plate form a plurality of horizontal water inlets. The utility model is enabled to make the rainwater become uniform and stable before flowing into the bucket base and therefore prevent whirlpool generation.
Description
Technical field
Utility model relates to a kind of draining roof drain, the anti-eddy-currents siphon roof drain on particularly a kind of drainage system against rain that is mainly used in large-scale roofing.
Background technology
Traditional roofing gravity drainage principle is based on the gradient of utilizing roof structure, water flows into the roof drain on the roofing naturally, water relies on action of gravity to descend along standpipe with the carbonated drink admixture then, and traditional rain water on roof exhaust system generally adopts pvc pipe, cast iron pipe, tin plate or cement asbestos pipe.Roof drain all adopts 65 types and 87 types basically, because monobucket flow maximum is no more than 12 liters/second, what often use is the roof drain of monobucket flow 3-6 liter/second.Whole system is owing to being the carbonated drink mixed flow, so PIPE DIAMETER CALCULATION is all bigger.Traditional roof drain generally all adopts an a pipeful of standpipe structure, and promptly the configuration mode of monobucket single system as improving drainage efficiency, needs to increase the quantity of roof drain and corresponding soil stack.
Present Chinese large tracts of land building roof, labyrinth roofing constantly increase, and traditional gravity current drainage system against rain originally can not satisfy the existing building designing requirement.Large tracts of land building roof, labyrinth roofing use traditional gravity current drainage system against rain will reach the rainwater discharge capacity that norm of construction require, a difficult problem of mainly meeting is as follows: roof drain quantity is too much, the storm-water system discharge capacity is too little, the storm-water system transverse tube is installed the gradient and had a strong impact on problems such as ceiling is decorated, rain leader downspout quantity is too much, when the many groups of installation roof drain on roofing, roofing certainly will form huge and complicated pipe network down, occupy the following a large amount of usefull space of roofing, cause unreasonable in the design, and construction costs is also corresponding increases considerably.
The utility model content
The purpose of this utility model provides a kind of low cost of manufacture, the anti-eddy-currents siphon roof drain that drainage effect is good, make that the gravity current of storm-water drainage becomes pressure flow in the prior art, be that the pressure reduction that rainwater passes through water level is discharged, when entering delivery pipe, rainwater do not form eddy-currents, owing to eliminated whirlpool, avoided sneaking into of a large amount of air.
The technical solution adopted in the utility model is: anti-eddy-currents siphon roof drain, comprise radome fairing, bucket seat and bucket body draining tail pipe, described bucket seat agent structure comprises an infundibulate disk body, and the disk body center is provided with weep hole, and this weep hole is connected with described bucket body draining tail pipe; Described radome fairing comprises a circle hat top board, and described top board and described bucket seat are affixed by bolt; Described radome fairing cover top surface is provided with a plurality of water conservancy diversion leaves that are radial arrangement along its center of circle, described top board periphery is provided with the corresponding discharge opening of a plurality of and described water conservancy diversion leaf; Be provided with a plurality ofly along the evenly distributed anti-whirlpool flow of circumference between described top board and the described bucket seat, described a plurality of anti-whirlpool flows and described bucket attic base body and top board constitute the water inlet of a plurality of horizontal directions.
The utility model further is set to: described bucket attic base body diameter is greater than the diameter of described top board, and evenly is provided with a plurality of installing holes on the external edge of described bucket attic base.
In the utility model, described bucket attic base body is provided with pressure ring, is provided with waterproof film between described bucket attic base body and the described pressure ring.
The utility model beneficial effect is owing to be provided with a plurality of water conservancy diversion leaves that are radial arrangement on top board, horizontal direction water inlet with a plurality of anti-whirlpool flows formations, and by the drainage gallery of radome fairing a plurality of radial arrangement that discharge opening constitutes, the rainwater uniform and stable that before flowing into the bucket seat, becomes, thereby destroy the condition that it forms whirlpool, can effectively stop air to enter pipe-line system along roof drain bucket seat draining tail pipe, prevent to produce whirlpool, and produce the siphon drainage effect, greatly improved the efficient of draining.
Description of drawings
Fig. 1 is a vertical view of the present utility model,
Fig. 2 is a structural representation of the present utility model.
The specific embodiment
Now in conjunction with the accompanying drawings the utility model is further described:
Referring to Fig. 1 to Fig. 2, showed a kind of embodiment of siphon roof drain among the figure:
Anti-eddy-currents siphon roof drain comprises radome fairing 1, bucket seat 2 and bucket body draining tail pipe 22, and bucket seat 2 agent structures comprise an infundibulate disk body 21, and disk body 21 centers are provided with weep hole 211, and weep hole 211 is connected with bucket body draining tail pipe 22; Radome fairing 1 comprises a circle hat top board 11, the top board 11 coaxial boss 12 that are provided with, and its effect is for guide functions, the discharge opening 112 that makes flowing water flow into top board 11 all sides is more swimmingly realized quick draining.
Owing on top board 11, be provided with a plurality of water conservancy diversion leaves 5 that are radial arrangement, horizontal direction water inlet with anti-whirlpool flow 111 formations, and by the drainage gallery of a plurality of radial arrangement that radome fairing discharge opening 112 constitutes, the rainwater uniform and stable that before flowing into bucket seat weep hole 211, becomes, thereby destroy the condition that it forms whirlpool, can effectively stop air to enter pipe-line system along roof drain bucket seat draining tail pipe 22, prevent to produce whirlpool, and produce the siphon drainage effect, greatly improved the efficient of draining.
In the present embodiment, the diameter of bucket attic base body 21 is greater than the diameter of top board 11, and is provided with the installing hole of a plurality of circumferential arrangement in bucket attic base body 21 outers, makes things convenient for the installation of siphon roof drain.
