Abstract
Description
Technical Field
[0001] The utility model relates to the field of subway transportation, in particular to a subway station interior decoration board with a water leakage detection function. Background Art
[0002] Most of the main structure of the subway station is located underground. For the sake of aesthetics, interior panels are installed on the walls and top of the subway station. The interior panels are mainly made of aluminum alloy decorative panels.
[0003] Inevitably, there will be water leakage in subway stations. In the early stage of leakage, the water only wets the local wall surface, and the staff cannot detect the leakage due to the obstruction of the interior panels. When water is found to flow out through the gaps in the interior panels, it indicates that the leakage is in the middle and late stages, which will cause two problems: first, the water leakage has caused certain damage to the main structure of the subway station, resulting in a significant increase in maintenance costs; second, the wet area has expanded, making it difficult to locate the leakage point. Utility Model Content
[0004] In order to overcome the shortcomings of the background technology, the utility model discloses a subway station interior panel with a water leakage detection function, and the subway station interior panel adopts the following technical solutions:
[0005] A subway station interior panel with a water leakage detection function, wherein a front array of the interior panel is provided with decorative holes, and a back array of the interior panel is provided with a water leakage detection unit; the water leakage detection unit is composed of a cylinder, lamp beads and a sponge; the cylinder is a conductor, fixed to the back of the interior panel, and connected to the negative pole of a power supply; the lamp beads and the sponge are installed in the cylinder, with the light-emitting surface of the lamp beads facing the decorative holes, one pin of the lamp beads connected to the positive pole of the power supply, and the other pin inserted into the sponge; after the interior panel is installed, the sponge is against the wall of the subway station.
[0006] To further improve the technical solution, a through hole is provided on the barrel, and one pin of the lamp bead passes through the through hole and is then connected to the positive pole of the power supply.
[0007] To further improve the technical solution, an insulating sleeve is provided at the via hole.
[0008] To further improve the technical solution, a ring platform is provided in the cylinder. After the interior panel is installed, one end of the sponge body abuts against the wall of the subway station, and the other end abuts against the ring platform.
[0009] To further improve the technical solution, the sponge is filled with granular salts.
[0010] To further improve the technical solution, the lamp beads are LED lamp beads.
[0011] After implementing the above technical solution, compared with the background technology, the beneficial effects produced by the utility model are:
[0012] The back of the interior panel of the subway station is provided with a water leakage detection unit, which is composed of a cylinder, a lamp bead and a sponge. When a leak occurs in the subway station, the sponge will absorb water and become conductive, causing the lamp bead to emit light. In this way, the staff can know whether a leak occurs in the subway station by observing the light, and can roughly determine the location of the leak. BRIEF DESCRIPTION OF THE DRAWINGS

For those skilled in the art, the specific meanings of the above terms in the present invention can be understood according to the specific circumstances.
[0019] As attached Figure 1 , Attachment Figure 2 As shown, a subway station interior panel 1 with a water leakage detection function is shown. The subway station interior panel 1 is made of aluminum alloy and has an anodized surface. Decorative holes are arranged in an array on the front of the subway station interior panel, and a water leakage detection unit 2 is arranged in an array on the back of the subway station interior panel. The structure and function of the water leakage detection unit 2 are described in detail below.
[0020] See attached Figure 3 The water leakage detection unit 2 is composed of a cylinder 21 , a lamp bead 22 and a sponge 23 . In this embodiment, the lamp bead 22 is an LED lamp bead 22 .
[0021] The cylinder 21 is a metal conductor, fixed to the back of the interior panel of the railway station. A negative electrode terminal 26 is welded on the cylinder 21, and the negative electrode terminal 26 is connected to the negative electrode of the power source. In this embodiment, the power source is a 5V DC power source.
[0022] The lamp bead 22 and the sponge 23 are installed in the barrel 21, the light-emitting surface of the lamp bead 22 faces the decorative hole, one pin 221 of the lamp bead 22 is connected to the positive pole of the power supply, and the other pin 221 is inserted into the sponge 23. In this embodiment, a through hole is provided on the barrel 21, and an insulating sleeve 24 is provided at the through hole. One pin 221 of the lamp bead 22 passes through the through hole and is then connected to the positive pole of the power supply through the positive electrode terminal 25.
[0023] A ring platform is provided in the cylinder body 21 , and another pin 221 of the lamp bead 22 passes through the ring platform and is inserted into the sponge body 23 .
[0024] See attached Figure 4 After the interior panel is installed on the wall 3 or the top of the subway station, one end of the sponge 23 is against the wall 3 of the subway station, and the other end is against the ring platform. The sponge 23 is elastic and has strong water absorption. After absorbing water, the sponge 23 has conductivity.
[0025] If leakage occurs in a local area of a subway station, the sponge 23 on the water leakage detection unit 2 corresponding to the infiltration area will be pressed against the leakage area, and the sponge 23 will be conductive due to water absorption. In this way, one pin 221 of the lamp bead 22 is connected to the positive pole of the power supply through the positive electrode terminal 25, and the other pin 221 is connected to the negative pole of the power supply through the sponge 23, the cylinder 21, and the negative electrode terminal 26, forming a loop, and the lamp bead 22 begins to emit light. Since the light-emitting surface of the lamp bead 22 faces the decorative hole, the staff can know whether there is a leakage in the subway station by observing the light, and can roughly determine the location of the leakage. The more water leakage detection units 2 are set, the more accurate the leakage location is.
[0026] To further improve the technical solution, granular salts are filled in the sponge 23. The salts can be sodium chloride, potassium chloride and other salts. Filling the sponge 23 with salts has two functions: first, the salts are hygroscopic, which is conducive to improving the water absorption of the sponge 23; second, after the salts are dissolved in water, the conductivity of the sponge 23 can be improved.
[0027] As can be seen from the above, a water leakage detection unit 2 is provided on the back of the interior panel 1 of the local subway station, and the water leakage detection unit 2 is composed of a cylinder 21, a lamp bead 22 and a sponge 23. When a leakage occurs in the subway station, the sponge 23 becomes conductive due to water absorption, and the lamp bead 22 emits light. In this way, the staff can know whether a leakage occurs in the subway station by observing the light, and can roughly determine the location of the leakage.
[0028] Although the embodiments of the present invention have been shown and described, it is understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present invention, and the protection scope of the present invention is defined by the attached claims and their equivalents.
