Abstract
The utility model relates to a protective cover for a rainfall meter, which is composed of an upper cylinder and a lower cylinder. The bottom end surface of the upper cylinder is reserved with a water outlet, the upper end surface of the lower cylinder is reserved with a water inlet, the water outlet and the water inlet are mutually butted, and a hollow connective device arranged at the butting point is used for connecting the upper cylinder and the lower cylinder into integration. The protective cover for a rainfall meter can be shaped by using a cold stamping stretching method, the traditional make method for conventional roll cylinder weld seam connection is replaced, the utility model is suitable for mechanization production, precision is not only improved, but also cost is reduced, and made shape is beautiful and unique.
Description
The utility model relates to a kind of rain gage protective cover that is applicable to the various types that departments such as meteorology, the hydrology, environmental protection, agricultural, national defence are commonly used.
The rain gage protective cover has the effect of holding rain and protection rain gage metering section.Rain gage protective cover at present commonly used all is straight up and down cylindric, tube high with the tube diameter ratio all more than 1.7 times.And so the cylinder of height is difficult to use cold stamping and stretching process machine-shaping, so generally all be that the plumber is rolled into cylinder with iron plate, through welding, becomes one again.The rain gage protective cover that adopts this molding mode to make, surface leave weld seam, not bright and clean, yielding, owing to be handwork, so the product irregularity of making, poor dimensional precision is difficult for large-scale industrial production, and the production cycle is long, cost is high again.Drench with rain owing to expose to the weather, the commissure is easily got rusty, is corroded, and has shortened serviceable life, has influenced udometric normal use.
The purpose of this utility model is a kind of novel rain gage protective cover of design, and this protective cover is suitable for suitability for industrialized production, and product surface is bright and clean, and shape is attractive in appearance, and is easy for installation.
The purpose of this utility model realizes by following scheme: the rain gage protective cover is made up of top cylinder and doffing two parts, the bottom face of top cylinder leaves water delivering orifice, water inlet is left in the upper surface of doffing, and water in-out port docks mutually, and the hollow coupling arrangement that joint is installed will be gone up doffing and be connected as a single entity.
This rain gage protective cover can be used the moulding of cold punching and drawing method, has substituted the traditional method that conventional reel weld seam connects, and is suitable for mechanization production, has not only improved precision, has reduced cost, and handsome in appearance, novel, peculiar.
Fig. 1 is a shape synoptic diagram of the present utility model
Fig. 2 is a partial sectional view of the present utility model
Fig. 3 is a cross section view of going up doffing water in-out port part in the utility model
Below in conjunction with accompanying drawing and to be with doffing on the infundibulate that embodiment specifies as follows:
By Fig. 1 and Fig. 2 as can be known, the rain gage protective cover is made up of top cylinder 1 and doffing 2 two parts.Wherein, top cylinder 1 plays the effect of collecting rainwater, and doffing 2 plays the metering unit effect of protection instrument.The bottom of top cylinder 1 is positive funnel-form, and its footpath mouth is a water delivering orifice 3; The upper surface of doffing 2 is down funnel-form, and its footpath mouth is a water inlet 4, and water in-out port 3,4 is butt joint and equal diameters mutually.A footpath mouthful joint passes a hollow coupling arrangement 9, and this coupling arrangement is cavity screw 5 and nut 6.Screw and nut will be gone up doffing 1,2 and be connected as a single entity.
As shown in Figure 3, the head of screw diameter of cavity screw 5 is greater than water in-out port 3,4, and head of screw is the shape that is inclined upwardly, with the funnel-form hypotenuse tight connecting of top cylinder 1; The upper surface of nut 6 is downward-sloping shape, with the anti-funnel-form hypotenuse tight connecting of doffing 2.For preventing to leak, between O-ring seal 7, two O-ring seals of each suit of the water in-out port place of last doffing pad 8 is arranged.
During installation, earlier O-ring seal 7 is enclosed within the water in-out port place of top cylinder 1 and doffing 2 respectively, consistency from top to bottom is also put into pad 8.Cavity screw 5 is passed the mouth place, footpath of top cylinder 1 and doffing 2, and the clamp nut 6 of screwing in the fastening process, should guarantee that the doffing axle center is concentric, and pad and O-ring seal are not pressed partially.
During use, shielding cover is contained on the rain gage base 10, during rainfall, rainwater enters top cylinder, flows into doffing 2 and enters udometric metering section along the endoporus of cavity screw 5, measures.
