Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a rainfall / snow collecting device that makes it particularly easy to collect snow for testing.

[0002]

[Prior art]

 One of the environmental destructions is air pollution due to sulfur oxides, which causes acid rain (acid snow) to damage the nature such as forests and lakes and the industries such as agriculture. To take measures against this, rainfall and snowfall are collected and their acidity is measured. For this test, rainfall / snow collectors have been used.

A conventional device of this type is provided with a hopper at the upper end of a vertically long box where rain and snow fall, a loading chamber for a collection container at the lower end, and a pipe between the hopper and the collection container. It was equipped with a device.

[0004]

[Problems to be solved by the device]

 According to the conventional rain / snow collecting device as described above, when the rain entering the hopper enters the collecting container through the pipe and filtering device and is filled with rainwater, the collecting container is taken out of the box and rainwater is collected. In the case of snowfall, it will not reach the collection container because the snowfall that has entered the hopper will remain there, especially at sub-zero temperatures, and there will be problems such as the filtration device becoming disabled due to freezing. There is a problem that not only snowfall but also rainfall cannot be collected.

Therefore, in the snowfall regions of Hokkaido, Tohoku, Hokuriku, etc., the snowfall was collected by leaving the buckets in the open field without using the collection device in winter, and therefore, as a precondition for the test, The laborious work of thawing and filtering has been forced.

In view of the above situation, the present invention does not require the trouble of thawing and filtering because snowfall is thawed and collected as water, and there is no trouble caused by freezing. The purpose was to provide a collection device.

[0007]

[Means for Solving the Problems]

 In order to achieve the above-mentioned object, the present invention has an inner tower of a hopper in which rain and snow fall down, which is installed on a box body, and inside the box body, a loading chamber for a collection container is provided at a lower end portion. In the rain / snow collection device with a filter installed on top of it, the interior tower is equipped with a heating heater that is activated by detecting the outside temperature to thaw the snowfall in the hopper. Has a built-in heat-retaining heater to prevent the freezing of water in it, and the heat-up heater is characterized by winding a self-controlling semiconductor around a hopper.

When the warming heater is an incandescent lamp that lights up when the outside air temperature is detected, and when the outside air temperature of at least the heating heater is detected by winding the temperature sensor around the hopper protruding from the upper end of the interior tower, More suitable for achievement.

[0009]

[Action]

 When snow falls on the hopper, the hopper is warmed by the heating heater, so the snowfall melts and flows down, is collected in the collection container through the filtration device, and when the water is flowing down or remains in the collection container, The freeze heater prevents freezing.

The heating heater is activated by detecting the outside air temperature, and the heating heater is a self-controlling semiconductor that does not overheat, and it is easy to transfer heat and is wound around the hopper. It

【Example】

 Next, an embodiment of the present invention will be described with reference to the drawings.

The rain / snow collecting device mainly comprises a vertically long box 1 as a case. However, in order to provide a hopper 3 for collecting rain and snow, the box 1 has an internal tower surrounding it at the upper end thereof. 2, a box 1 is provided with a loading chamber 4 for a collection container 5 at the lower end thereof, and a filtering device 7 is provided thereon. Then, the snowfall falling into the hopper 3 is thawed by the warming heater 11, and the water keeping inside the box 1 is prevented from freezing by the warming heater 13.

The box body 1 is assembled into a vertically long rectangular cube in a structure in which an aluminum wall plate is supported by a frame, has an opening / closing door 15 on the front surface, and the upper end communicates with the interior tower 2. Therefore, the temperature of the heat retention heater 13 reaches the hopper 3. Reference numeral 6 is a supporting leg as a base for receiving the box body 1.

The inner tower 2 has a quadrangle at the lower end according to the shape of the box body 1, but is formed like a truncated cone that becomes narrower toward the upper end so that snowfall does not occur, and the hopper 3 is formed therein. It is held and has an insulating space suitable for its heating between this shape and the hopper 3.

The hopper 3 is made of polyethylene and has an upper end projecting outward from the upper end of the interior tower 2, and the outer circumference of the projection is used to start the warming heater 11 and the warming heater 13 to cool the outside temperature and A temperature sensor 17 for detecting the temperature of the hopper 3 is wound around, and the outside is covered with an outer cover 19 made of an aluminum thin plate or aluminum foil. Excessive heating of the hopper 3 is also prevented by this temperature sensor 17.

The heating heater 11 is also a self-controlling semiconductor heater suitable for preventing excessive heating, and is located in the space between the interior tower 2 and the hopper 3 so as to transfer heat directly to the hopper 3. , Is wound around the outside of the hopper 3. A relay container 23 made of glass is connected to the flowing water pipe 21 from the hopper 3.

The collection container 5 is a polypropylene bottle, and a funnel 27 is inserted into the stopper of the mouth of the collection container 5. The filtering device 7 puts a filter paper between the relay container 23 and the funnel 27. It has a sandwiched structure. 29 is the pinching tool. In order to allow this picking, a brim is provided on the relay container 23 and the funnel 27 so that the picking tool 29 can be hooked.

An air vent pipe 31 is connected to the relay container 23, and a tip portion 33 of the air vent pipe 31 projects outward from the inner tower 2 at the upper end. The air vent pipe 31 is also used for overflow of water.

A wooden plate 35 is attached to the rear wall of the box body 1 near the filtering device 7, and in addition to the warming heater 13, a temperature controller 37 of the warming heater 11 and an earth leakage breaker 39 are provided. Equipped. As the heat-retaining heater 13, a red-light bulb (tungsten bulb) that easily warms the inside of the box body 1 and is easy to maintain is used.

In the temperature controller 37, if the temperature is set to, for example, 5 ° C., when the outside air temperature falls below that temperature, the warming heater 11 and the warming heater 13 are turned on and the temperature is higher than that temperature. Expire at. The temperature sensor 17 is shared by the warming heater 11 and the warming heater 13. However, the warming heater 13 may be provided with a separate temperature sensor or may be provided with a switch without being provided. good.

[Effect of device]

 As described above, the present invention has the following excellent effects.

Not only can it be used throughout the four seasons, but in winter, snow can be thawed and collected as filtered water in a collection container, so there is no troublesome work such as thawing and filtering snow. There is no problem of freezing of water inside, and water can be collected as it is for testing even during snowfall.

Since the heating heater is activated by detecting the outside air temperature and the self-controlling semiconductor is wound around the hopper, snowfall can be reasonably solved and energy saving is suitable.
