Problems solved by technology

[0002] There is currently no detection method for detecting rainfall except the rain gauge, and the rain gauge can only be used in continuous light rain or intermittent moderate rain or heavy rain. Its starting point sensitivity is the average rainfall of 0.1mm / min. When the accumulation reaches a certain value, a pulse signal will be output. Its working principle is to use the tipping bucket structure. When the raindrops in the tipping bucket are full, it will output a pulse signal; for light rain or even drizzle or intermittent light rain, it cannot Immediate perception, and the gamma radiation dose rate will cause a sharp increase in the gamma radiation dose rate of the environment even if there is a slight drizzle

Embodiment Construction

[0011] The grid-shaped high-sensitivity rain and snow detector has a gold-coated or gold-plated grid-shaped film-sensing rain plate 8. The gold-coated or gold-plated grid-shaped film-sensing rain plate 8 is connected to the anti-corrosion composite metal heating plate 5 through stainless steel connecting screws 7, and the anti-corrosion composite metal is heated. There is a groove on the bottom of the plate 5, and a rubber sealing strip 4 is embedded in the groove. There are mounting screws on the outside of the bottom groove of the anti-corrosion combined metal heating plate 5, and it is connected with the stainless steel junction box 2. The anti-corrosion combined metal heating plate The constant temperature control is controlled by the miniature bimetallic switch type thermostat 9 installed at the bottom, the stainless steel junction box 2 is installed with the terminal 3, the stainless steel junction box 2 is welded on the bottom plate of the stainless steel sleeve 1, and th...

Abstract

This invention discloses a palisade detector for rain and snow and rain with high accuracy. It possesses palisade rain sensitive board with gold coating and plating which is connected with antiseptic combined metal heating board through non-corrosive steel attachment screws. On the bottom of antiseptic combined metal heating board locates a slots outside which installed a fixing screws and is connected with non-corrosive steel joint box and the constant temperature of antiseptic combined metal heating board is controlled by a micro double metal switch located on the bottom of it. The advantages are the following: 1, the minimal single rain particular is 0.3mm enough to satisfy the needs of environment detecting; 2, to have high anti-interference ability against fog, frost and dew; 3, to react to the rain measured within 0.1 seconds.

Description

technical field [0001] The invention relates to a grid-shaped high-sensitivity rain and snow detector. It is mainly used in meteorological parameter collection, environmental protection monitoring, agricultural production arrangement, transportation management and many other fields. Especially in the environmental nuclear radiation monitoring of nuclear power plants, the radon value will increase rapidly due to rainfall, which affects the detection of gamma radiation dose rate. Therefore, rainfall has a great impact on the detection of gamma radiation dose rate. Therefore, it is necessary to accurately know whether the increase in gamma radiation dose rate is due to changes caused by rainfall or changes caused by nuclear radiation leakage from nuclear power plants. Background technique [0002] There is currently no detection method for detecting rainfall except the rain gauge, and the rain gauge can only be used in continuous light rain or intermittent moderate rain or hea...
