Abstract

PURPOSE:To operate an alarm device in accordance with the short circuit of a pair of electrodes due to water leak by arranging a trough directly under a pipe laid onto the back of a ceiling and arranging a detector equipped with at least a pair of electrodes which are short-circuited by water onto the bottom part of the trough. CONSTITUTION:When water leaks from a pipe 1, said water penetrates into a heat insulation covering 2, and water drips down into a trough 13 from the joint or divided part of the skin of the heat insulating covering 2, and a pair of electrodes 15 of a detector 14 laid on the bottom part of the trough 13 are short-circuited. The dripping water is intercepted by a partitioning plate 19 installed into the trough 13, and the flow-out to other part is prevented, and since the heat insulating cover 2 is divided, it serves for shedding water, and dripping of leak water onto other part of the trough 13 is prevented, and only the electrode 15 at the water leak position is certainly short-circuited.

Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to a water leakage detection device).The present invention relates to a water leakage detection device. It is related to the device.

[Conventional technology]

Conventionally, cold water or hot water piping (1
) is coated with heat insulation coating (C) as needed, and this heat insulation coating (C) is divided into appropriate lengths and placed on the ceiling (A) of factories etc.
However, in the event of a leak, it would not be possible to detect it until the water had dripped onto the roof (in most cases, indoors). This could cause damage to products.

In other words, when water leaks from the pipe (/), the water permeates the insulation coating (C) and then drips into the ceiling, wetting the insulation material and lighting equipment (C1, etc.) installed in the ceiling, which contains water. If the air conditioner is no longer able to clean, it can leak into the air-conditioned room (
Drip into Dl. Therefore, a water leak phenomenon can only be discovered after a considerable amount of time has elapsed since water actually leaked from the pipe (/) and when it dripped into the room.

[Problem that the invention seeks to solve]

As mentioned above, in the past, a considerable amount of time elapsed between the time when water was generated and when it was discovered, so a large amount of water was wetted on the insulation material in the ceiling, and then dripped onto the products placed indoors or around them. Not only did this cause damage, but it also took time to check the location of the water leak, leading to further damage.

This invention is intended to solve the above-mentioned problems, and allows water leakage from piping to be discovered at an early stage, and
An object of the present invention is to obtain a water leakage detection device that can easily confirm the location of water leakage.

[Means for solving problems]

The water leakage detection device according to the present invention includes an insulating gutter installed in parallel directly below the pipes installed in the attic, and a detection body equipped with at least/a pair of electrodes short-circuited by water arranged at the bottom of the gutter, An alarm device is activated in response to a short circuit between the opposite electrodes due to water leakage.

[Function] In this invention, water leaking from the piping is collected in the gutter,
A short circuit between the electrodes at a predetermined location/pair will trigger the alarm, so that the occurrence and location of the water leak will be immediately known.

〔Example〕

Figures 1 to q show an embodiment of the present invention;
In Figure 2, Ii! is suspended directly below the pipe (1)! (/
According to l), a gutter (/3) made of an insulating material is arranged parallel to the pipe (1) to collect water leaking from the pipe (1). Gutter (/J

A pair of electrodes (/) are arranged on the outer surface of an insulated wire (/4'a) at appropriate intervals.
A plurality of pairs of /ri may be provided as necessary.

The detection object (/ll) is guided to a place where a supervisor is stationed, such as a central monitoring room, by a guide M (/A) for each section of the heat insulation coating (Y) of the piping (1), and an alarm such as a buzzer is sent to the detection object (/ll). A power source C (not shown) is used to operate the device.

The electrode (/l) and alarm device (/7) are connected in series.

In addition, in order to identify the location of water leakage, a partition plate (/d) was installed in the gutter (/3) for each section of the heat insulation coating (c), and 7 pairs of electrodes (/d) were installed for each section of the insulation coating (c). Ic is made to correspond independently.

With the above configuration, when water leaks from the pipe (/), it penetrates into the thermal insulation coating (2) and drips into the gutter (/J) from the seam or separation of the skin of the thermal insulation coating (2). Detection object (/ri) installed at the bottom of the gutter (/3)
short-circuit the pair of electrodes (/).The dropped water flows into the gutter (t
It is installed in the gutter and is dammed by a partition plate (/tsu) installed in the gutter, and the water does not leak to other parts.Since the insulation wave is separated, this is the water drainer. (/
Since the water does not drip to other parts of J), only the electrode (13) at the leakage part is reliably short-circuited, and the alarm device (/) corresponding to the part in the central monitoring room is alerted to the occurrence of water leakage and its location. will be reported at an early stage.

As a result of the above-mentioned effects, the origin of water leakage can be easily confirmed in a wide area such as behind the ceiling, and countermeasures and treatments can be speeded up.

In the above embodiments, water leakage detection was described for water piping coated with a heat insulating coating, but similar effects can be obtained even when the present invention is applied to pipes without a heat insulating coating.

Also, it is not necessary to increase the number of electrodes (/3); instead, the gutter (/3) should be sloped appropriately to collect leakage water at each length of the pipe (1) that can be easily divided, and electrodes should be placed in each section. You can.

〔Effect of the invention〕

As is clear from the above description, the present invention includes insulating gutters arranged in parallel directly under the piping, a detection body having a pair of electrodes placed at the bottom of the gutters, and detection of the pair of electrodes caused by water leakage. Since the alarm is triggered by a short circuit, the following effects are brought about.

(1) Since water leakage can be detected at an early stage, damage to incidental equipment such as stored products and insulation materials in the ceiling can be prevented.

(1:) Since the origin of water leakage can be clearly identified, there is no need to investigate a wide area behind the ceiling, and countermeasures and treatment can be taken quickly.

(liil) Therefore, the repair cost of 4 water is significantly reduced.
