Embodiment 1

[0032] This embodiment is a hardened ground evaporation monitoring system, such as figure 1 , 2 shown. This embodiment includes: water consumption monitoring subsystem 1 installed in pairs on the monitored hardened ground 3 (water consumption includes: the total amount of water evaporated and infiltrated) and infiltration monitoring subsystem 2 (monitoring only the amount of water infiltrated) , the main body of the water consumption monitoring subsystem is a water consumption bottomless bucket 101 that is watertightly connected to the monitored hardened ground, and a water consumption flow sensor 102 is provided near the upper edge of the water consumption bottomless bucket. Water sprinkler 103, the water consumption level sensor 104 is set near the position of the bottomless bucket of water consumption; the main body of the infiltration monitoring subsystem is exactly the same size and shape as the bottomless bucket of water consumption The infiltration bottomless barrel 2...

Embodiment 2

[0047] This embodiment is an improvement of the first embodiment, and is a refinement of the material of the water-consuming bottomless bucket and the infiltration bottomless bucket of the first embodiment. The water-consuming bottomless barrel described in this embodiment uses materials with good light energy transmission, and the infiltration bottomless barrel and cover plate use materials that are heat-insulating and light-insulating.

[0048] A material that transmits light energy well mainly refers to a material that can transmit infrared rays well, because the main energy that can evaporate water in light comes from infrared rays and red light. Therefore, materials such as glass or plexiglass can be used for water-consuming bottomless buckets.

[0049] In order to reduce the cost, the infiltration bottomless barrel and the cover plate can also be made of the same material as the water consumption bottomless barrel, but the paint that can insulate heat and light energy is...

Embodiment 3

[0051] This embodiment is an improvement of the above embodiment, and is a refinement of the horizontal section of the water consumption bottomless bucket and the infiltration bottomless bucket of the above embodiment. The horizontal section shape of the water consumption bottomless bucket and the infiltration bottomless bucket described in this embodiment is one of circle, rectangle and polygon.

[0052] The horizontal cross-sectional shape of the bottomless bucket is the shape of the end surface of the bucket, which can be circular or other shapes. The determination of this shape mainly depends on the profile used. bucket.

Abstract

The invention relates to a hardened ground evaporation monitoring system and method, which includes: water consumption monitoring and infiltration monitoring subsystems. The main body of the water consumption monitoring subsystem is a water consumption bottomless bucket. The water consumption bottomless bucket is equipped with a water consumption flow rate. The water consumption sprinkler of the sensor, the water consumption liquid level sensor is installed near the ground in the water consumption bottomless bucket; the main body of the infiltration monitoring subsystem is the infiltration bottomless bucket, and the top of the infiltration bottomless bucket is equipped with a watertight connection cover , the infiltration bottomless barrel is equipped with a sprinkler with an infiltration flow sensor, and an infiltration liquid level sensor is installed near the ground in the infiltration bottomless barrel. The beneficial effects produced by the present invention are: by monitoring and comparing the total water consumption and infiltration water volume of evaporation and infiltration in two bottomless barrels with completely equal enclosure areas, the present invention obtains the evaporation water volume of urban hard ground and realizes the evaporation of urban hard ground. The prototype measurement of capacity and evaporation rate provides a simple and economical tool for evaporation monitoring of urban hardened ground and provides technical support for urban hydrological monitoring.

Description

technical field [0001] The invention relates to a hardened ground evaporation monitoring system and method, which is a hydrological monitoring system and method, and a monitoring system and method suitable for the evaporation capacity of different types of hardened ground in urban areas. Background technique [0002] Evapotranspiration is the recharge source of atmospheric precipitation and an important link in the hydrological cycle. In the small inland cycle, ground evaporation and vegetation transpiration are the main recharge sources, especially in areas with little water area, which is the case for most urban areas in China. The proportion of hardened ground in cities is very high, generally reaching 85%-90%, but in the current urban hydrological research, the evaporation of hardened ground is rarely considered and measured. The actual situation is that the hardened ground will intercept rainwater and cause evaporation, and at the same time, artificial watering on some...
