Description

Technical Field

[0001] The utility model relates to the technical field of disaster early warning, in particular to an agricultural meteorological disaster early warning device. Background Art

[0002] Agricultural meteorological disasters include heat damage and frost damage caused by temperature, or drought and flood disasters caused by moisture.

[0003] The current agricultural meteorological disaster warning device needs to use a rain gauge when detecting rainfall. In order to prevent the entry of impurities, a filter is often set in the water inlet of the rain gauge for filtering. In order to prevent rainwater from splashing to the outside when it falls on the filter, the filter is located relatively deep, which makes it easy for a large amount of debris to accumulate on the filter, making it inconvenient to clean. At the same time, the rainwater collected by the general rain gauge after completing the rainfall detection is mostly discharged directly, which is relatively wasteful. Therefore, there is a need for an agricultural meteorological disaster warning device that can use the discharged rainwater to clean the filter. Utility Model Content

[0004] In view of the above situation, in order to overcome the defects of the prior art, the present scheme provides an agricultural meteorological disaster early warning device, which is achieved by the following specific technical means: it includes a device rod, on which a meteorological environment detector is arranged, and at the same time, a rain gauge shell is arranged at the top of the device rod, and a support ring is arranged on the inner wall deep inside the top opening of the rain gauge shell, and a filter is placed on the support ring, and a push-up control mechanism is arranged in the rain gauge shell, and the push-up control mechanism is connected to the filter, and is used to intermittently push the filter out of the top opening of the rain gauge shell and stand it upright, and a nozzle is connected to the rain gauge shell through a pipe, and rainwater sprayed from the nozzle is used to flush the erected filter.

[0005] Preferred technical solution 1: A fixed seat is provided on the outer wall of the top opening of the rain gauge housing, and the push-up control mechanism includes a sliding rod and a telescopic rod, the sliding rod is provided on the fixed seat, the bottom end of the sliding rod slides through the filter and is provided on the support ring, a convex frame is provided below the support ring in the rain gauge housing, the telescopic rod is hinged on the convex frame and the top end is hinged to the bottom wall of the filter, and the filter is controlled to slide along the sliding rod by the telescopic movement of the telescopic rod. The nozzle is provided on the fixed seat.

[0006] Preferred technical solution two: the sliding rod is composed of a vertical rod portion and a horizontal and oblique rod portion, the bottom end of the vertical rod portion is arranged on a supporting ring, the end of the horizontal and oblique rod portion is arranged on a fixed seat, the top end of the vertical rod portion and the other end of the horizontal and oblique rod portion are smoothly connected in an arc shape, and the top end of the vertical rod extends out of the top opening of the rain gauge housing.

[0007] Preferred technical solution three: A water level sensor is provided inside the rain gauge housing.

[0008] Preferred technical solution four: A drain pipe is provided at the bottom of the rain gauge housing, and a flow meter is provided on the drain pipe.

[0009] Preferred technical solution five: A fine filter element is arranged below the protrusion in the rain gauge housing.

[0010] Preferred technical solution six: the nozzle is an electric nozzle.

[0011] The above structure enables this solution to have the following beneficial effects:

[0012] After each heavy rain, after detecting the rainfall, the telescopic rod is used to extend and push the filter out of the top of the rain gauge shell and stand it upright. At this time, the collected rainwater is sprayed out through the nozzle to flush the upright filter to prevent large particles from blocking the filter. At the same time, there is no need to set up a cleaning liquid separately. BRIEF DESCRIPTION OF THE DRAWINGS
