Description
Technical field
The utility model belongs to rainwater field of measuring technique, and in particular to a kind of antifreeze rainfall gauge.
Background technology
Rainfall gauge is the instrument that a kind of meteorologist and hydrologist are used for measuring the precipitation in somewhere in a period of time,
It common are hydrocone type, tipping bucket type, Weighing type etc..In the prior art, in the area of colder climate, it is necessary to simultaneously to rainwater
In the case of being measured with snow, more using weighing type rain gauge.
Weighing type rain gauge because temperature is too low in the winter time in use, may make electronic device break down；In addition, work as
Under low temperature sleety weather, sleet may freeze when falling on raingauge receiver or funnel, or even further block up scupper
Plug, causes rainfall gauge can not normal work.
Utility model content
For the deficiency in the presence of prior art, the utility model, which provides one kind, can prevent electronic device from low temperature occurs
Failure, it is avoided that the rainfall gauge that scupper blocks.
A kind of antifreeze rainfall gauge, including housing, the raingauge receiver of case top is arranged on, and it is arranged on the leakage of enclosure interior
Bucket, water storage device, weighing device and control unit, the funnel are arranged on raingauge receiver inwall, and the water storage device is positioned at leakage
Below bucket and it is placed on weighing device, the weighing device is connected with control unit；Also include being arranged on the enclosure interior
The first heating module and temperature sensor, the temperature sensor is separately positioned on weighing device and control unit, described
First heating module and temperature sensor are connected with control unit respectively.
Further, pressure sensor is additionally provided with the scupper of the funnel and is set on the outside of funnel second adds
Thermal modules, the pressure sensor and the second heating module are connected with control unit respectively.
Further, the inner surface of the raingauge receiver and funnel is super hydrophobic surface.
Compared to prior art, the utility model has the advantages that：
1st, by setting hygrosensor and heating module in housing, the control to environment temperature in rainfall gauge is realized
System, ensure that other electronic devices will not damage because temperature is too low；
2nd, by setting pressure sensor and heating module on funnel, it can effectively prevent the scupper of funnel from occurring to block up
Plug, and then solve the problems, such as that the rainfall gauge caused by blocking can not normal work.
Brief description of the drawings
Fig. 1 is the utility model structure diagram.
Wherein, 1- raingauge receivers, 2- funnels, 3- water storage devices, 4- weighing devices, 5- control units, 6- housings, 7- first add
Thermal modules, the heating modules of 8- second.
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 antifreeze rainfall gauge, as shown in figure 1, including housing 6, being arranged on the raingauge receiver 1 at the top of housing 6, and set
Funnel 2, water storage device 3 inside housing 6, weighing device 4, control unit 5, the funnel 2 are arranged on the inwall of raingauge receiver 1
On, the water storage device 3 is located at the lower section of funnel 2 and is placed on weighing device 4, and the weighing device 4 connects with control unit 5
Connect；Also include being arranged on the first heating module 7 and the temperature sensor inside the housing 6, the temperature sensor is set respectively
Put on weighing device 4 and control unit 5, first heating module 7 and temperature sensor are connected with control unit 5 respectively.
The weighing device can use electronic scale.Described control unit can use PLC.
In the winter time under the severe cold weather in field, the electronic device in rainfall counter device may be because temperature it is too low and can not work
Make even to damage, the utility model is provided with heating module in enclosure interior, when temperature sensor detects the temperature of electronic device
When spending low (for example temperature is less than -20 DEG C), control unit sends heating instructions to heating module.In view of energy consumption and control
The problem of evaporation, heating-up temperature should not be too high, degree that heating module will not damage temperature control in device (such as -10 DEG C
Between~-5 DEG C).
So, by setting temperature sensor and heater in housing, realize to rainfall gauge housing inner ring
The control of border temperature, it ensure that other electronic devices will not damage because temperature is too low.
Embodiment 2：
On the basis of the scheme of embodiment 1, it is additionally provided with pressure sensor at the scupper of the funnel 2 and is set in Lou
The second heating module 8 on the outside of struggling against, the pressure sensor and the second heating module 8 are connected with control unit 5 respectively.
When snowfall occurs, if snowfall is larger, accumulated snow may be caused on raingauge receiver and funnel even by leak
Mouth blocks, and similar clogging also occurs when sleet occurs.When scupper accumulated snow blocks, temperature sensor meeting
Detect whole device and be in low-temperature condition, while pressure sensor can detect lasting pressure, if now when pressure exceedes
Accumulated snow signal can be sent to control unit by pressure sensor during some threshold value, and control unit controls the second heating module to be heated to
Suitable temperature (such as 5~10 DEG C) makes the snow generation thawing at scupper fall into water storage device so as to no longer block scupper.
By setting pressure sensor and the second heating module, it can effectively prevent the scupper of funnel from blocking, enter
And solve the problems, such as the rainfall gauge caused by blocking can not normal work.So, just at last when snowing also without general
Raingauge receiver and funnel pull down change into it is special hold snow device just can normal work, the scheme of the present embodiment is adapted to some positions more inclined
The rainfall gauge that out-of-the-way, unattended, device changes inconvenience uses.
Embodiment 3：
On the basis of the scheme of embodiment 2, the inner surface of the raingauge receiver 1 and funnel 2 is super hydrophobic surface.Or holding
Super-hydrophobic coat is set also may be used on the inner surface of hydrophone 1 and funnel 2.
The super hydrophobic surface can allow the flow velocity of raindrop to be accelerated, moreover it is possible to prevent rainwater from adsorbing, reduce rainwater and encounter low temperature
Rain container or funnel after occur freezeout probability, coordinate the second heating module can effectively by sleet be sent into water storage dress
Put.
Preferred embodiment of the present utility model is the foregoing is only, on the scope of protection of the utility model is not limited in
Embodiment is stated, every technical scheme for belonging to the utility model principle belongs to the scope of protection of the utility model.For this
For the technical staff in field, some improvement for being carried out on the premise of principle of the present utility model is not departed from, these improvement
It should be regarded as the scope of protection of the utility model.
