[Detailed description of the device]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a membrane dew condensation detector for a membrane structure used for detecting the dew condensation state of the membrane surface of a membrane structure.

[0002]

2. Description of the Related Art In order to control the operation of an exhaust fan at the top of a dome with a temperature detector and a film surface dew condensation detector, there is no established method for detecting film surface dew condensation. At present, there is a plan to attach the sensor directly to the film surface, for example.

[0003]

By the way, in the method of directly attaching the sensor to the film surface, since the Teflon film is easily peeled off, the sensor is not durable, and the film may be damaged by the protrusion of the dew condensation sensor. There was a drawback.

The present invention was developed in order to solve the above-mentioned problems, and an object thereof is to provide a film surface dew condensation detector capable of effectively detecting without damaging the film.

[0005]

In order to achieve the above object, in the present invention, a cord-like water leakage detection sensor is formed in an arc shape.

[0006]

Embodiments will be described below based on the illustrated embodiments.
Reference numeral 1 denotes a strip-shaped water leak detection sensor. This water leak detection sensor 1 is bent in an arc shape, and its top portion 1a has a sensor coating surface 1b peeled off by a required length as shown in FIG.

A wire 2 is backed along the water leakage detection sensor 1 as a reinforcing material. Further, the heat-shrinkable tube 3 is coated on a portion other than the periphery of the top of the water-leakage detection sensor 1 which is a contact portion with the film surface, and the end portion of the heat-shrinkable tube 3 is subjected to caulking treatment 4 for stopping water. . Further, on both left and right ends of the water leak detection sensor 1, an attachment plate made of a synthetic resin plate 5 such as a vinyl chloride plate and a metal plate 6 such as an aluminum plate is attached, and via the attachment plate,
Rod-shaped fixing pieces 7 made of wood pieces are laid across both left and right sides of the water leakage detection sensor 1. Symbol 8 indicates a terminal block.

In use, as shown in FIGS. 5 and 6, detection is performed by bringing the top of the water leakage detection sensor 1 into contact with the inside of the film surface A.

[0009]

As described above, according to the present invention, the strip-shaped water leak detection sensor portion is bent in an arc shape and is formed so as to abut against the film surface at the top thereof, so that the film surface can be effectively detected without being damaged.

Further, since the reinforcing material is backed along the water leakage detection sensor with appropriate strength, the water leakage detection sensor abuts on the film surface without deforming the shape of the film surface and while maintaining the shape. be able to.

Further, since the heat-shrinkable tube covers the portion other than the membrane surface contact portion of the water leakage detection sensor, only the contact portion with the membrane is detected, so that the response is good.
