DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention is a measuring device for measuring temperature or humidity in the atmosphere, in which wind is forced to the measurement sensor only during daytime sunlight. The present invention relates to an electric ventilation type temperature / humidity measuring device adapted to be applied.

(Prior Art) Generally, when accurately measuring temperature or humidity in the atmosphere,
Forced ventilation is performed by a fan in order to make the air around the measurement sensor in the measurement device the same as the atmospheric state.

(Technical problem) In the conventional technology, a cable and other equipment for transmitting electric power for driving the fan motor are required for forced ventilation of the measuring device in a remote area such as a mountain, which results in high cost. Therefore, it is conceivable to use a battery, but since the motor is rotated for 24 hours, the consumption of the battery becomes significant.

In the past, in order to accurately measure the temperature or humidity in the atmosphere in remote areas such as mountains, there were the above-mentioned problems in capital investment and problems in maintaining battery life. In particular, ventilation in the measuring device is important for measuring the temperature and humidity of the atmosphere during the day, but there has been no electric ventilation measuring device that can be practically used in remote areas such as mountains.

Therefore, in the present invention, in the meteorological observation especially in an unmanned remote area, the ventilation fan motor is rotated by using the irradiation energy of sunlight to forcibly apply the wind to the measurement sensor of the thermometer or the hygrometer for accurate measurement. While measuring temperature and humidity,
The purpose is to reduce costs.

(Technical Means) In order to achieve the above-mentioned object, the electric ventilation type temperature and humidity measuring device of the present invention comprises a ventilation cylinder and a top, and the ventilation cylinder has a plurality of umbrella-shaped plates arranged at predetermined intervals. And a ventilation fan motor is positioned close to one of the openings formed by perforating the central portion of the umbrella plate, and a thermometer is measured at the other opening. A sensor or a hygrometer measurement sensor is freely inserted and installed,
It is characterized in that the solar cell attached to the top and the ventilation fan motor are connected.

It is characterized in that the above-mentioned top portion is provided with a variable elevation angle mechanism portion, and the solar cell is assembled in a roof shape and attached to the top portion.

The first embodiment of the electric ventilation type temperature and humidity measuring device of the present invention
This will be described with reference to FIGS. The following is a description of an electric ventilation type temperature measuring device, which is an embodiment of the electric ventilation type temperature and humidity measuring device of the present invention, equipped with a thermometer measurement sensor.

In the figure, reference numeral 1 is an electric ventilation type temperature measuring device of the present embodiment, and the electric ventilation type temperature measuring device 1 is composed of a ventilation cylinder 5 and a top portion thereof.

The ventilation cylinder 5 has four layers of umbrella-shaped plates (3A, 3B, 3C, 3D), which are formed in a substantially vertical side surface, and are stacked at required intervals by the mounting posts 4 to form a four-layer board. ing. With this configuration, the ventilation tube body 5 has a multi-layered peripheral side surface with peripheral side surface openings (8A, 8B, 8C) as shown in the figure, and in actuality has a skeleton-like mounting shape with no peripheral side surface. There is. This umbrella plate (3A, 3B, 3C, 3
D) is formed of a synthetic resin, an aluminum plate, a silver plate, or the like.

The umbrella-shaped plate 3A forms the upper surface of the ventilation cylinder 5, and the top is attached at the position shown in the figure. In addition, a synthetic resin plate is coated on the upper surface of the umbrella-shaped plate 3A with a reflective film formed by vapor deposition of aluminum, silver, or the like to block radiant heat from the sun, so that the space between the umbrella-shaped plate 3A and the umbrella-shaped plate 3B is reduced. The temperature inside the space P is prevented from rising.

In the figure, 6A is an opening penetrating the central portion of the umbrella-shaped plate 3B, and 6B is an opening penetrating the central portion of the umbrella-shaped plate 3C. On the umbrella-shaped plate 3B, the ventilation fan motor 7 is positioned and installed close to the opening 6A,
The ventilation fan 7A is located above the opening 6A.

The thermometer measurement sensor 9 is internally inserted in the opening 6B in the vertical direction in the drawing. As a result, the thermometer measurement sensor 9 is vertically installed at the substantially center of the ventilation cylinder 5. The output signal of the thermometer measurement sensor 9 is connected to the electric circuit in the box 10 attached to the lower part of the ventilation tube 5.

The solar cell 2 is assembled in a roof shape and attached to the top of the ventilation cylinder 5. The elevation angle θ of the solar cell 2 is adjusted by the elevation angle varying mechanism member 2B provided at the top. This solar cell 2
As shown in Fig. 3 and Fig. 4, the roof-shaped left and right slopes are aligned with the direction of the latitude of the sky through which the sun passes, and the ridge 2A is oriented in a substantially south direction with a slight elevation angle θ. It is a gable roof type. The electric power of the solar cell 2 is connected to the input of the ventilation fan motor 7. In the figure, 11 is a stick for avoiding birds. The solar cell may be replaced with a roof type so that the elevation angle θ of the flat panel solar cell is variable as shown in FIG.

With the above configuration, the ventilation fan motor 7 rotates when receiving electric power from the solar cell 2, and the ventilation fan 7A is rotated to suck the lower air from the opening 6A and the umbrella plate 3A through the space P. The air is exhausted through the peripheral side surface opening 8A between 3B and 3B. At the lower side of the opening 6A, the atmosphere is sucked and guided from the peripheral side surface opening 8B between the umbrella-shaped plates 3B and 3C and the peripheral side surface opening 8C between the umbrella-shaped plates 3C and 3D, This atmosphere further has openings 6B and 6
It is sucked into the central portion of the space P via A and. At that time, the atmosphere is forcibly applied to almost the entire circumferential surface of the thermometer measurement sensor 9.

(Operation) The operation of this embodiment will be described below. The ventilation fan motor 7 is rotated by the electric power of the gable roof type solar cell 2. At that time, since the sun light is strongly received on a sunny day, the rotation speed of the ventilation fan motor 7 is high, the thermometer measurement sensor 9 receives strong air flow, and on a cloudy day, the light from the sun is weak. The rotation speed of the ventilation fan motor 7 becomes low, the ventilation to the thermometer measurement sensor 9 becomes weak, and the ventilation fan motor 7 rotates according to the weather.

Next, the atmosphere sucked from the lower peripheral side surface openings 8B and 8C by the rotation of the ventilation fan 7A is sucked toward the space P side through the openings 6A and 6B, and then through the peripheral side surface opening 8A. The air can be exhausted outward from the peripheral side surface.

The thermometer measurement sensor 9 provided in the opening 6B of the ventilation tube 5 is always exposed to the atmosphere and can maintain the air permeability at all times, and the temperature of the atmosphere can be measured by following the temperature change of the atmosphere. It is done in real time.

In addition, since the solar cell 2 is assembled in a gable roof type, morning, noon,
The sunlight can be effectively received even when the position of the sun in the evening changes. Note that in nighttime and in rainy weather, the ventilation fan motor 7 is stopped and natural ventilation is provided.

The electric ventilation type temperature measuring device 1 which is an embodiment of the electric ventilation type temperature and humidity measuring device of the present invention has the function described above, and the electric power of the solar cell 2 is proportional to the intensity of the sunlight.
Is proportionally rotated to suck the atmosphere, and the atmosphere is guided by the umbrella-shaped plates (3B, 3C, 3D) and directly hits the thermometer measurement sensor 9, thereby preventing the accumulation of air and accurately measuring the temperature. Is to do.

Further, instead of the thermometer measuring sensor 9 constituting the above-mentioned embodiment, a hygrometer measuring sensor is internally provided in the opening 6B, and an output signal of the hygrometer measuring sensor is attached to a lower part of the ventilation tube body 5. It is easy to construct an electric ventilation type humidity measuring device which is another embodiment of the electric ventilation type temperature and humidity measuring device of the present invention by connecting to the electric circuit in the box 10.

(Effect) The electric ventilation type temperature and humidity measuring device of the present invention has the following effects.

(A) In particular, in a daytime no wind condition or a slight breeze condition where the sun shines and becomes high temperature, the ventilation by the ventilation fan motor rotating with the solar cell and its power directly hits the measurement sensor of the thermometer or hygrometer. Due to the interaction with the constructed ventilation cylinder, the electric ventilation type temperature and humidity measuring device of the present invention does not have stagnation of air in the measuring device, so that the temperature and humidity of the atmosphere can be measured with high accuracy.

(B) Since the ventilation fan motor also rotates in proportion to the intensity of sunlight, the wind contact with the thermometer measurement sensor or the hygrometer measurement sensor is also proportional and the measurement accuracy is improved.

(C) Power wiring or a power source such as a wet or dry battery that needs to be regularly replaced or replenished is not necessary, so it is extremely practical for temperature and humidity measurement in remote areas of the mountain, and capital investment and maintenance Is also economical.

(D) By assembling the solar cells in a roof shape,
Even when the position of the sun changes in the evening, the light energy of the sun can be efficiently received, and the rotation of the ventilation fan motor can be smoothly and efficiently maintained.
