Compared to prior art, the utility model has the advantages that：
1st, there is provided an entrance between funnel and water storage device to export horizontal water inlet pipe, phase vertically for the utility model
For traditional structure, whereabouts momentum when rainwater enters water storage device can be substantially reduced, it symmetrically will not be interfered again；
2nd, whereabouts rainwater flows into water storage device along water storage device side wall, whereabouts momentum can be further reduced, when making to weigh
The disturbing factor can be ignored；
3rd, by setting hydrophobic surface or hydrophobic coating, it can prevent rainwater is adhered in container or pipeline to cause ponding,
Rainwater flow resistance can also be reduced.

Embodiment
In order that technological means, creation characteristic, reached purpose and effect that utility model is realized are easy to understand, below
With reference to being specifically illustrating, the utility model is expanded on further.
Embodiment 1：
A kind of weighing type rain gauge, as shown in figure 1, including raingauge receiver 1, funnel 2, water storage device 3, weighing device 4, control
Unit 5 and the housing 6 for being surrounded said structure, the funnel 2 are arranged on the inwall of raingauge receiver 1, the water storage device 3
Positioned at the lower section of funnel 2 and it is placed on weighing device 4, in addition to water inlet pipe 7, outlet pipe 8, the upper end of water inlet pipe 7 and funnel 2
End connects, and lower end is connected to the side wall of water storage device 3 and connected close to the position of bottom, the bottom of water storage device 3 with outlet pipe 8
Connect；The water inlet pipe 7 in bending set, the axial direction of the upper end porch of water inlet pipe 7 vertically, the axle in lower end exit
To in the horizontal direction.The weighing device can use electronic scale, and the water storage device can use drum ladle.In water inlet pipe
7 and outlet pipe 8 on also settable magnetic valve be connected with control unit, water intaking valve 9 namely for control rainwater entrance and control
The outlet valve 10 of rainwater outflow water storage device processed.
Water inlet pipe is bent in the present embodiment and set, on the one hand allows rainwater to be fallen vertically until outlet from water inlet pipe porch
The horizontal outflow in place, can effectively reduce influence of the rainwater whereabouts momentum to weighing device；Another aspect shaped form water route can also allow
Ponding is not easy in water inlet pipe, reduces measurement error.
As a further optimization of the scheme , the pipeline edge between the upper end porch and lower end exit of the water inlet pipe 7
Circle cycloid curve is set.
If due to object from high point drop to the low spot of non-vertical lower section when, along circle cycloid fall the time required to it is most short, such as
This setting can make flow velocity of the rainwater in water inlet pipe reach maximum, and current can be on the premise of avoiding momentum from influenceing weighing device
It is rapid to flow into water storage device, the efficiency for draining of catchmenting can be improved when rainwater is larger.
