Problems solved by technology

[0003] The lower end of the traditional rain gauge is fixed to the ground by fixing feet and bolts. The installation cost is high and the installation is complicated. In addition, in windy and windy weather, impurities such as leaves may fall into the water collection bucket. The leaves may block the dust filter and affect the measurement results

Embodiment 1

[0019] Such as figure 1 and figure 2 As shown, a hydrological rain gauge that is easy to erect includes a water measuring cylinder 1 and a sleeve 2; the sleeve 2 is installed on the top of the water measuring cylinder 1. The limit ring 10 formed integrally with the sleeve 2 is provided with a first internal thread under the limit ring 10, and the outer wall of the upper end of the water measuring cylinder 1 is provided with a first external thread screwed with the first internal thread to facilitate disassembly of the sleeve 2; The outer wall of the upper end of the sleeve 2 is provided with a holding part 4, and the holding part 4 may be a symmetrically arranged holding rod, or an annularly arranged holding ring. The gripping part 4 is used for gripping by the operator, and is provided with anti-slip sleeves or anti-slip lines. The lower end of the water measuring cylinder 1 is fixedly connected with a stabilizing plate 5. When the rain gauge is erected, the stabilizing pl...

Embodiment 2

[0022] The difference between this embodiment and Embodiment 1 is that: the side wall of the sleeve 2 is provided with a plurality of discharge grooves 8, the lower edge of the discharge grooves 8 is higher than the bottom circumference of the dust cover 3, and the discharge grooves 8 are arc-shaped through the slot.

[0023] The dust cover 3 and the inner wall of the sleeve 2 can be threaded. In this embodiment, the lower end of the dust cover 3 is fixedly connected with a protruding ring 7 integrally formed with the dust cover 3 , the outer surface of the protruding ring 7 is provided with a second external thread, and the sleeve 2 is located above the limit ring 10 with a The second internal thread screwed with the second external thread, the protruding ring 7 is threadedly connected with the inner wall of the sleeve 2, which facilitates disassembly and installation of the dust cover, and facilitates cleaning of the dust cover 3. The lower edge of the discharge groove 8 is...

Abstract

The invention discloses a hydrology rain gauge easy to erect. The hydrology rain gauge comprises a water measurement barrel and a sleeve, and the sleeve is installed on the upper portion of the watermeasurement barrel; a stable disc is arranged at the lower end of the water measurement barrel, and a fixed drill pipe is arranged at the lower end of the stable disc; a conical dust cover is arrangedinside the sleeve, the circumference of the bottom of the dust cover is installed on the inner wall of the sleeve, a leveling instrument is installed at the top of the dust cover, and water leaking holes are uniformly distributed in the surface of the dust cover; a holding component is arranged at the upper end of the sleeve. The hydrology rain gauge is easy to erect during usage, and can guarantee the effect of metering rainfall.

Description

technical field [0001] The invention relates to a rain gauge used in the field of hydrological research, in particular to a rain gauge which is easy to erect in the field. Background technique [0002] Hydrology refers to various phenomena such as changes and movements of water in nature. Hydrology now generally refers to a discipline that studies the temporal and spatial distribution and change laws of natural water. The rain gauge is a special instrument used to collect precipitation, and is used to measure the precipitation in millimeters through the matching rain gauge cylinder. It is suitable for meteorological stations (stations), hydrological stations, environmental protection, flood control and drainage, agriculture, forestry and other relevant departments to measure precipitation. The water receiving port of the traditional rain gauge is made of cast copper, and the cylinder body is formed by soldering stainless steel plates. [0003] The lower end of the traditi...
