Problems solved by technology

[0009] However, in the former liquid leakage detector of the above-mentioned prior art, since the substrate 41 constituting the sensor part 40 is in the form of a sheet, the installation location is limited, and when the sensor part 40 is installed on the sensor installation surface, attachments are required. With the sticking parts, installation takes man-hours
[0010] However, the latter liquid leakage detector of the above-mentioned prior art is installed on the bottom surface of the automatic vending machine through the threaded part passing through the threaded hole provided on the support body, and there is a problem that the installation takes man-hours.
[0011] In addition, as a conventional liquid leakage detector, there is also a photoelectric type liquid leakage detector that detects liquid leakage by irradiating light to the leaked liquid. , there is a problem that accessories need to be installed, and installation takes man-hours

Embodiment 1

[0055] Embodiment 1 of the present invention consists of Figure 1 to Figure 9 Shows. figure 1 It is a structural explanatory diagram of Embodiment 1 of the liquid leakage detector of the present invention, figure 2 It is the front view of the sensor part of this liquid leakage detector, image 3 is a bottom view of the sensor section, Figure 4 is a cross-sectional view of the sensor section, Figure 5 is along image 3 Partially omitted cross-sectional view of the X-X line in the middle, Image 6 is along Figure 4 Partially omitted cross-sectional view of the Y-Y line in the middle.

[0056] The liquid leakage detector F of the present invention is composed of a sensor unit A for detecting a liquid leakage, and a device main body (amplifier unit) B.

[0057] This equipment main body (amplifier part) B has a signal transmission circuit, a level setting part, a comparison part, a liquid leakage output part, and a display part (none of which are shown in the figure), ...

Embodiment 2

[0077] Embodiment 2 of the present invention is in Figure 10 to Figure 13 shown in .

[0078] In Embodiment 2 of the present invention, in the sensor part A, the female thread part 26 is formed on the inner surface of the hollow cylindrical guide part 13 provided on the base body 3, and the female thread part 26 is added to the mounting hole G, The other structures are the same as those of Embodiment 1 of the present invention. Therefore, it is possible to install the sensor unit A on the sensor installation surface 30 without using the nut member 32 .

[0079] That is, if Figure 11 As shown, by screwing the internal thread portion 26 of the mounting hole G of the sensor part A to the stud bolt 31, the sensor part A is rotated, as shown in FIG. Figure 12 As shown, the sensor part A is installed on the sensor installation surface 30 . In addition, the operation of the liquid leakage detector F is the same as that of the first embodiment of the present invention described...

Embodiment 3

[0082] Embodiment 3 of the present invention is in Figure 14 to Figure 17 shown in .

[0083] In Embodiment 3 of the present invention, in the sensor part A, the internal thread part 26 is formed on the inner surface of the hollow cylindrical guide part 13 provided on the base body 3, and the cover body 2 is not provided with the hole part 10. The internal thread portion 26 is added to the hole G, and the mounting hole 10 is a bottomed hole. The other configurations are the same as those in the first embodiment of the present invention described above. Therefore, it is possible to install the sensor unit A on the sensor installation surface 30 without using the nut member 32 .

Abstract

In the situation of installing sensor on sensor installation surface, it needs install fixed member or sticking member and wastes labor hours in installation. It proceeds by installing the hole G for installation in sensor A. When installing sensor A onto the sensor installation surface 30, it inserts stud bolt 31 installed on sensor installation surface 30 into the said hole G for installation and pierces hole G, then threading nut member 32 on the stud bolt 31 and tighten said nut member 32.

Description

technical field [0001] The present invention relates to a liquid leakage detector for detecting liquid leakage, dew condensation, etc., such as water, chemical liquid, and the like. Background technique [0002] As a liquid leakage detector that detects liquid leakage by the inter-electrode resistance detection method, there are Figure 20 The liquid leakage detector of the shown sensor part 40, the liquid leakage detection belt which detects the area of ​​a liquid leakage, the liquid leakage detector which performs point inspection and detection of a liquid leakage, etc. are shown. [0003] Figure 20 The sensor portion 40 of the shown liquid leakage detector is to make an electrode 42 made of a comb-shaped conductive pattern and another electrode 42 made of a comb-shaped conductive pattern on the back surface of a plate-shaped hard substrate 41. 43. There are gaps and interlockingly interlocking to form a structure. [0004] From the signal transmission circuit of the dev...
