Description
Technical field
The invention belongs to en-toutcas, more particularly, to carries out the assay device of water-resistant performance test to en-toutcas,
The rain test device and test method of specifically a kind of en-toutcas.
Background technology
In order to ensure en-toutcas dispatch from the factory before water-resistant performance, have clear stipulaties to need to carry out examination of drenching with rain to en-toutcas in GB
Test, test method is to open umbrella support, make umbrella stem perpendicular to the ground, and the rotating speed of umbrella cover 5r/min is rotated around umbrella stem, injection flow rate
（3.6±0.5）L/min, and make whole umbrella cover that device is drenched with rain in the range of drenching with rain, specifically as shown in figure 1, in 2min
Situation in observation umbrella cover, does not drop down when umbrella stem and does not drip in water, umbrella cover and obvious vaporific drainage, illustrate the parachute kit for good
Good water-resistant performance.
But this is drenched with rain there is problems with device：1）When the shower nozzle for being adopted is sprinkled water to umbrella cover, what shower nozzle sprayed
Waterline is outwards radial by center, it is impossible to vertical landing state when simulation is rained naturally very well, along with umbrella cover has
Certain radian, causes the water yield that umbrella cover is received everywhere uneven, and the marginal position of umbrella cover even cannot be by shower nozzle ejection
Water is covered, it is impossible to the real rainfall scene of accurate simulation；2）The computational methods of injection flow rate are the water received within the unit interval
Amount cumulative volume, this computational methods are not related to the size of measuring surface, it is impossible to make accommodation to different umbrella cover areas, spray water
Amount cannot effective equal control；3）And which does not define apopore position, the pore size of apopore, the water outlet uniformity and umbrella
The factors of influence such as area coverage, what each laboratory was measured differ greatly, it is impossible to which standard is unified well.
The content of the invention
In order to overcome the deficiencies in the prior art, the shower water that a kind of umbrella cover of present invention offer is received is more uniform, test
As a result it is stable, can preferably simulate the rain test device and test method of the en-toutcas of true rainfall scene.
The technical solution adopted for the present invention to solve the technical problems is：A kind of rain test device of en-toutcas, including
Spray equipment, the pluviometer for determining spray flux and the tumbler for driving umbrella stem to rotate, the spray equipment include
The water inlet pipe for being provided with regulating valve and the water distribution pipe network for being used for uniform water outlet on fixed frame, the online uniform cloth of the water distributor
The outlet component of multiple settings perpendicular to the ground is provided with, the outlet component is included located at the online mounting seat of water distributor and grafting
Syringe needle in the mounting seat.
A kind of rain test device of en-toutcas of the present invention, has the advantages that：
1st, outlet component is arranged perpendicular to ground, and the scene of true rainfall in more life-like simulation natural environment, umbrella cover are each
The water spray that place receives is more uniform.
2nd, spray flux is determined using pluviometer.Pluviometer is for measuring the precipitation in certain region in a period of time height.It is logical
Often, pluviometer is by raingauge receiver（Funnel）, water storage cylinder（Outer tube）, water-storing bottle composition, and be furnished with the private volumn proportional to its bore
Cup.Precipitation height of the udometric measurement unit for the unit time, such as mm/min, thus the size of its result and test zone without
Close, closer to truth, and the concordance of test result is high.
3rd, the syringe needle is connected in mounting seat by inserting mode, and the aperture of syringe needle can be matched somebody with somebody according to test request
Put and change.Also, syringe needle installation and removal are very convenient.
4th, syringe needle can adopt commercially available medical needle, and low price is with low cost.
Further, the mounting seat is adhesively fixed online in the water distributor by heating or glue.Water distribution pipe network by
Thermoplastic is made, and mounting seat is also thermoplasticity material, by heating fixed mounting and water distribution pipe network, not only processing technique
Simply, and it is completely embedded, consolidates；Water distribution pipe network can be that common plastics tube is processed, and draw materials conveniently.
Further, the mounting seat is with the first union joint being connected with the syringe needle, first union joint and institute
The contact surface for stating syringe needle is taper seat.
Further, the mounting seat is also had second union joint being connected with the water distribution pipe network and is connected by second
The flange that joint bottom is outwards extended, the second described union joint are inserted in the online perforate of the water distributor, described flange
Upper surface is offseted with the outer surface of water distribution pipe network.
Further, the spacing between the adjacent outlet component is 50 ± 5mm.Multiple outlet components are formed（50±5）X
（50±5）Square structure, it is ensured that the water droplet dropped on umbrella cover is uniformly distributed, and umbrella cover everywhere can by water spray cover, protect
The effectiveness of card performance test.
Further, the aperture of the syringe needle is 0.3-0.6mm.
Preferably, the aperture of the syringe needle is 0.4mm.
Further, the spray equipment is more than or equal to 500mm with the spacing of umbrella cover.
Further, the water distribution pipe network is horizontally disposed with, and which includes an at least outfall sewer and vertical with the outfall sewer
The exit branch of connection.Outfall sewer is used to connect each exit branch, is easy to water distribution pipe network zones of different to form annular channels,
So that supplying water can rapidly and uniformly be distributed to water distribution pipe network everywhere.
Further, the water distribution pipe network includes multiple water distribution regions, and the water inlet pipe is provided with multiple branch roads, branch road
Terminal is connected with the center of outfall sewer in water distribution region.Water in water inlet pipe rapidly and uniformly can be drawn by branch road
Turn on the zones of different to water distribution pipe network so that the current in water distribution pipe network obtain dispersed at short notice.
The invention also discloses a kind of salt fog test method of en-toutcas, comprises the following steps：
1) measure the amount of rainfall pluviometer eccentrically mounted on tumbler, and make rainfall reach setting by regulating valve；
2) umbrella support is opened, is fixed on tumbler, with the rotating speed of 5 ± 0.5r/min around umbrella stem synchronous rotary, with setting
Rainfall carries out test 2min；
3) device of drenching with rain is closed after 2min, observes situation in umbrella cover at once, be confirmed whether to reach test request.
Pluviometer is followed into tumbler and umbrella stem synchronous rotary, so as in the case where spray equipment is motionless, it is ensured that rain
Gauge receives the precipitation of zones of different, in the case of can simulating natural precipitation, the irregularities of rainfall；Rainfall is adjusted to
The water level that certain region is improved in per minute, rather than traditional per minute interior accumulative rainfall volume, computational methods are not related to survey
The size in amount region, has fully ensured that the rainfall that umbrella cover is received, has improve the effectiveness of test, reduced to different weathers
The diversity of the test of umbrella so that the data that each laboratory is measured more are unified.
The invention has the beneficial effects as follows：Whole device more truly simulates the real scene of natural precipitation, and umbrella cover is each
The precipitation that place receives is more uniform, also ensure that the total amount of the precipitation that umbrella cover is an actually-received, and simple structure, and processing is just
It is prompt；The test method of the present invention changes the computational methods of conventional statistics rainfall, improves the effective of en-toutcas performance test
Property, reduce the difference of different en-toutcas performance tests.
