Problems solved by technology
The rain gauge needs to measure the volume of rainwater collected in it after a period of time to obtain the amount of rainfall, which is inconvenient
[0003] For some rainwater collection devices, when the rainfall is large, the container can be filled with rainwater in a short time. At this time, there are no reminder devices to indicate the degree of full or shallow rainwater, or the indicator device is more complicated and inconvenient to use. is an area that needs improvement

Embodiment Construction
[0018] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.
[0019] See figure 1 , the present invention includes a container 1 for collecting rainwater and a base 2 for installing the container 1 from the appearance. Several LED lamps 22 and control switches 21 for the LED lamps 22 are arranged around the base 2 .
[0020] See figure 2 , figure 2 It is a schematic diagram of an embodiment of the present invention. In this embodiment, the side wall 11 of the container is turned down to form a cavity 12, the cavity 12 is matched with the side wall 27 of the base, the side wall 27 of the base can be inserted into the cavity 12 matched therewith, and can be further Inserting and withdrawing realize the purpose of vertical lifting of the container 1 on the base 2 . A rheostat device is provided between the container 1 and the base 2, and the rheostat device includes a metal block 14 arranged on the bo...

A rainwater collection device with LED indication function, comprising a container for collecting rainwater and a base for installing the container, characterized in that the container can be lifted vertically on the base, and the base is provided with The LED lamp and the control switch of the LED lamp, a rheostat device is arranged between the container and the base, and the rheostat device forms a circuit with the power supply, the LED lamp, and the control switch, and a circuit is also provided between the container and the base. elastic piece. The container can be lifted vertically on the base. When it rains, the device is placed in the rain and the switch is turned on. At this time, the resistance of the rheostat device is relatively large, the current in the circuit is small, and the LED light is dark; When there is more and more rain, the compressed elastic part of the container descends, and the greater the decline, the smaller the resistance of the variable resistance device, the larger the current in the circuit, and the brighter the LED lights. Therefore, we can judge the amount of rainwater in the container according to the brightness and darkness of the LED light, and can also indicate the size of the rainfall by the speed at which the LED light turns bright.
Description
technical field [0001] The invention belongs to the field of precipitation observation and collection, in particular to a rainwater collection device with an LED indication function. Background technique [0002] There is a lot of rain in the south of the Yangtze River in my country, especially in the spring and summer seasons, when showers and heavy rains often occur. When it rains, we can judge the amount of rainfall according to the amount of rainwater falling into the container within a certain period of time, that is, through the rain gauge. The rain gauge needs to measure the volume of rainwater collected in it after a period of time to obtain the amount of rainfall, which is relatively inconvenient. [0003] For some rainwater collection devices, when the rainfall is large, the container can be filled with rainwater in a short time. At this time, there are no reminder devices to indicate the degree of full or shallow rainwater, or the indicator device is more complic...
