Problems solved by technology

[0004] At present, my country's meteorological and hydrological departments generally use the artificial measuring cup method, siphon rain gauge and evaporator to measure rainfall and evaporation. The manual measuring cup method is a primitive measurement and siphon rain gauge method, which does not meet the needs of modern technological development. , with large human error
Generally, it is only necessary to place a rainfall and evaporation device at the observation point, and it is time-consuming and labor-intensive for the observers to go to the site tomorrow to read the data at a fixed point. A single rainfall

Embodiment

[0031] The main support 2 is welded with 50 mm diameter steel pipes into a length of 0.5 meters each, each corresponding to the cross arm pallet support 3; the cross arm pallet support 3 is screwed and installed at different heights and different directions of the main support 2, and the main support 2 is made of wire rope 7. Ground anchor steel drill 8. Wire flower basket 9 is tightened and fixed.

[0032] The sensor tray 4 is installed on the cross arm tray bracket 3; the rain gauge cylinder 1 is installed on the sensor tray 4, and the level of the rain gauge cylinder 1 is adjusted with the horizontal fixing screw 14. The rainwater collected at the water receiving port of the rain gauge cylinder 1 passes through the funnel 10 in the cylinder and is injected into the meter. In the tipping bucket 10, the metering tipping bucket 10 is injection-molded of engineering plastic and divided into two equal-volume triangular compartments with a middle partition. It is a mechanical bistabl...

Abstract

A crop canopy gradient rainfall remote collecting instrument comprises rainfall gauges, a main support, horizontal arm tray supports, trays, a main support locating disk, funnels, sensing trays, metering tipping buckets, a solar cell panel, a solar charging circuit, a lithium cell, a multi-path data collector, a GPRS remote controller and a remote network computer. The four horizontal arm tray supports are bridged on the main support at different heights and in the four directions, the trays are arranged at the tail ends of the horizontal arm tray supports, the rainfall gauges are arranged on the trays, the funnels, the sensing trays and the metering tipping buckets are arranged in the rainfall gauges, the main support is fixed by the main support locating disk, and the solar cell panel and a GPRS remote antenna are arranged on the main support. Due to the fact that the rainfall gauges are arranged on the main support at the different heights and in the different directions, the data accuracy of the crop canopy gradient rainfall remote collecting instrument can be guaranteed. Thus, original data can be provided for flood protection, water supply dispatching and water management of power station water reservoirs.

Description

Technical field [0001] The invention relates to a remote measuring device for collecting rainfall in different gradients of farmland canopy, in particular to a remote collecting instrument for crop canopy gradient rainfall. Background technique [0002] The shortage of water and soil resources and the deterioration of the ecological environment have become a serious problem of widespread concern all over the world, which makes people realize the importance of saving water and protecting the environment. In order to ensure food security and the sound development of the ecological environment, it is necessary to strengthen the management of farmland water and soil resources and the study of ecosystem reconstruction, handle the relationship between water resource utilization and ecological reconstruction, and vigorously promote water-saving irrigation technology and rainwater resource utilization technology. With water resources as the main constraint, adjust the layout of the agric...
