Problems solved by technology
[0005] During the pouring process of removing the water from the rain container, more water will adhere to the cup wall of the rain container, especially when the water volume in the rain container is small, which will lead to the failure to measure the water volume in the container.
[0006] (2) The return of the rain container is not allowed
All methods that require the rain container to be removed from its original position for water measurement cannot guarantee that the rain container can be accurately restored to its original position.
[0008] (3) It takes a long time to measure the water consumption of the rain container
In the case of multiple rain storage devices, the cumulative time will be longer, and often when the second rainfall comes, the previous rainfall and the rainfall in the forest have not been measured.

Embodiment Construction
[0033] The specific embodiments of the present invention will be further described in detail below in conjunction with the accompanying drawings.
[0034] The method for quickly measuring the water volume of the rain container of the present embodiment comprises the following steps:
[0035] Step a: Push the piston 2 of the water measuring cylinder with a hole in the bottom into the bottom end of the water measuring cylinder 1 with a hole in the bottom, and connect one end of the hose-type water transmission conduit 3 with the water measuring cylinder 1 with a hole in the bottom. The water outlet hole 11 at the bottom is connected, and the other end of the hose type water transmission conduit 3 is connected with the needle type round end water intake probe 4;
[0036] Step b: Immerse the needle-type round-end water-taking probe 4 into the water, and pull the piston 2 of the water measuring cylinder with a hole in the bottom until the pinhole-type water measuring cylinder 1 wit...

The invention provides a rapid measuring method for water amount of a rain container and belongs to a rainfall measuring method. The method is that rainwater in the rain container is pumped in situ, direct reading is performed in the water-pumping measuring device so as to complete measurement work, and the rain container does not need to be moved and poured. The rapid measuring method for the water amount of the rain container can achieve measurement of rainfall amount in situ of the rain container, and is rapid in measurement velocity, accurate in measurement result and particularly remarkable when water amount in the rain container is low.
Description
technical field [0001] The invention discloses a method for rapidly measuring the water volume of a rain container, which belongs to a method for measuring rainfall. Background technique [0002] In the global change, the change of rainfall distribution pattern is becoming more and more obvious. In a rainfall event, the accurate measurement of rainfall and rainfall in the forest plays an important role in studying the law of forest rainfall redistribution and evaluating the water conservation function of forests. [0003] At this stage, rainwater is mostly stored in bottled containers and its volume is measured. It is measured by pouring water into a special rain cup and reading the rainfall or pouring it into an ordinary measuring cup or cylinder to measure the rainfall. However, this method has the following disadvantages: [0004] (1) Inaccurate or unable to measure a small amount of water in the rain container [0005] During the pouring process of removing the water...
