とのできる市販のフィルムを利用すればよい。The present invention will be described below in more detail with reference to the illustrated embodiments. 1 and 2 show a first embodiment of the present invention, in which 1 is an outer case and 2 is a water storage case supported therein. The water storage case 2 is made of hard plastic, and is a container having a capacity of 2 liters in the embodiment. A water injection port 3 is provided at the lower end of the water storage case 2, and is connected to a solenoid valve 5 of an insulator pollution degree measuring device by a flexible tube 4 to inject water, for example, about 5 cc each time measurement is performed. A water impermeable air inlet 6 is formed at the upper end of the water storage case 2. In order to form such an air inlet 6, a commercially available film that does not allow water to pass but allows air to pass may be used.

Is provided. The pushing spring 7 is a coil spring, and by selecting the spring constant thereof, the entire water storage case 2 can be pushed up by the amount of weight reduction of the water storage case 2 caused by water injection.

いうえ、蒸発による液量減少を防止することもできる。In the water pouring tank of the first embodiment constructed as described above, when the water storage case 2 is filled with a large amount of water, the pushing spring 7 bends as shown in FIG. The whole is in a low position. Further, when the amount of water in the water storage case 2 decreases due to water injection, the push spring 7 pushes up the entire water storage case 2 by the amount of weight reduction due to the decrease.
Therefore, as shown in FIG. 2, the height H of the liquid surface inside the water storage case 2 is always kept substantially constant, and it is possible to prevent a change in the amount of water injected into the solenoid valve 5. In addition, since the outside air flows in from the water impermeable air inlet 6 with the water injection, the inside of the water storage case 2 is always kept at the atmospheric pressure, the water injection is not hindered, and the liquid amount reduction due to evaporation is prevented. You can also

る。FIG. 3 shows a second embodiment of the present invention, in which the water storage case 2 is made of flexible plastic. The push spring 7 pushes up the bottom surface 2a of the water storage case 2 so that the liquid level is always at a certain position slightly below the ceiling surface 1a of the outer case 1. It should be noted that the ceiling surface 1a of the outer case 1 is provided with an air hole 1b communicating with the water impermeable air inlet 6 at the upper end of the water storage case 2 so that water does not escape and atmospheric pressure is applied to the liquid surface of the water storage case 2. Is acting on.

定した液面制御が可能となる利点がある。The water pouring tank of the second embodiment constructed as described above functions similarly to the first embodiment, but the liquid level is constantly maintained without forming a space inside the water storage case 2. Since it is located at a fixed position slightly below the ceiling surface 1a of the outer case 1, more stable water injection can be performed. That is, in the first embodiment, the pushing spring 7
The liquid surface is kept constant depending on the balance between the elastic force and the weight of the outer case 1. However, in the second embodiment, by setting the push spring 7 to be stronger, the liquid surface is always kept in the outer case 1. Since it can be made constant a little below the ceiling surface 1a, there is an advantage that more stable liquid level control can be performed.

とができるものである。As described above, in the water injection tanks of the first and second inventions, even when the amount of liquid inside the water storage case decreases due to water injection, the action of the push spring keeps the liquid surface constant. Therefore, there is an advantage that the water injection amount can always be kept constant. Further, since the water injection tank of the present invention does not require a complicated mechanism such as a metering pump, when applied to, for example, an insulator pollution degree measuring device, its structure can be simplified and the measurement can be performed. The accuracy can be improved.
