Description

Automatic udometer

Technical field

The utility model relates to the rainfall metering outfit, is specifically related to the automatic udometer that departments such as a kind of meteorology and the hydrology are used for measuring the amount of rainfall.

Background technology

At present, domestic and international traditional udometer mainly adopts dual mode: a kind of is with a funneling iron sheet system rain receiver, a glass cylinder; Another kind is a funneling iron sheet system rain receiver, with a plastic tube rainwater is introduced indoorly, again with the mode of glass cylinder amount rainfall amount, but has the defective of the following aspects:

1, is subjected to man's activity, is easy to generate numerical error.

2, plastic tube outside the exposure chamber, breaks all the year round easily, causes the excessive phenomenon of rainwater, measures inaccurate.

3, rain receiver adopts ironwork, and tenure of use is not long, needs to change.

4, the rain receiver capacity is little, as runs into heavy rain or heavy showers, and rainwater easily overflows rain receiver.

5, precipitation gauge is a glassware, artificial easily the damage.

6, original udometer does not have the storing mode of rainfall continuous data.

Because above-mentioned shortcoming is unsuitable for extensively promoting in villages and small towns precipitation observation station.

The utility model content

The technical matters that the utility model solved is to provide a kind of automatic udometer, to solve the shortcoming in the above-mentioned background technology.

The technical matters that the utility model solved realizes by the following technical solutions:

Automatically udometer comprises base bucket, rain receiver, liquid level conduit, fluid level controller, water receiving pipe, rising pipe, ultrasonic flow meter, power supply; Described base bucket is the drum that employing stainless steel weldering system forms, and the bucket end is three solid cylinder footings of distribution evenly, and there is the ring of guiding and supporting of two symmetries in the base bucket outside, is convenient to lift udometer; Described rain receiver is the bowl structure that is welded in the base bucket, and upper diameter is identical with base bucket internal diameter, and with base barrel upper surface flush, bottom centre position leaves apopore, the bottom also is provided with water-guiding hole along the limit; Described liquid level conduit is a L type stainless-steel tube, be communicated with the rain receiver bottom along the water-guiding hole on limit and extend to outside the base bucket, upwards vertically bend and extend to the mouth of pipe and the same plane of base bucket then, the effect of liquid level conduit is that the rainwater in the rain receiver is derived, and makes that the interior water level of water level and rain receiver in the liquid level conduit is in same surface level; Described fluid level controller is a float-type liquid level controller, is installed on the liquid level conduit; Described water receiving pipe adopts two stainless-steel tubes, is installed on the apopore of rain receiver bottom centre position, and one is equipped with motor operated switch, and another root is equipped with hand switch; Described rising pipe and water receiving pipe are connected, and stretch out outside the bucket from base bucket bottom; Described ultrasonic flow meter is installed on the rising pipe, and utilizes data line and the display that is installed on the base bucket is connected, and rainfall amount is calculated and show on display; In addition, the utility model also is equiped with power supply, utilizes lead to link to each other with each consumer, for it provides power.

In the utility model, the control line of described motor operated switch links to each other with fluid level controller.

In the utility model, described hand switch is provided with and stretches out the outer handle of base bucket.

In the utility model, be provided with ring stiffener between described liquid level conduit and the base bucket.

The utility model principle of work is as follows:

Rainwater falls into rain receiver, just begun motor operated switch and hand switch is closure state, at this moment, rainwater in the rain receiver can be along with flowing into the liquid level conduit, and the water level in liquid level conduit and the rain receiver is consistent, when rainfall amount is bigger, after the water level in the liquid level conduit has surpassed predetermined water level, fluid level controller in the liquid level conduit can be controlled motor operated switch and open, and the rainwater in the rain receiver flows out from the rising pipe of bottom; When rainfall amount is very little, the water level in the liquid level conduit has not surpassed predetermined water level thereby can not trigger motor operated switch when opening, and can open hand switch after rainfall stops, and allows the rainwater in the rain receiver flow out from the rising pipe of bottom; Rainwater is when rising pipe flows out, and ultrasonic flow meter can calculate amount of rainfall, and with on the present display of effective aspect.

Beneficial effect: the utility model is simple in structure, and is easy to operate, can realize the automatic measurement of udometer to quantity of precipitation, and measuring error is less.
