Abstract
Description
Technical Field
[0001] The utility model relates to the field of subway stations, in particular to a water leakage locating device for subway stations. 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 water leakage locating device, which adopts the following technical solutions:
[0005] A water leakage locating device for a subway station comprises a frame fixed on the wall of the subway station and used for fixing an interior trim panel, a sponge board and an insulating board are fixed in the frame, and the sponge board is close to the wall; transverse needle bars and longitudinal needle bars are arranged in an array on the insulating board, and the transverse needle bars and the longitudinal needle bars each have a plurality of equidistant electrode probes; the electrode probes on the transverse needle bars and the longitudinal needle bars penetrate the insulating board and are inserted into the sponge board to form a plurality of groups of electrode pairs arranged in an array; each transverse needle bar and each longitudinal needle bar is respectively connected to a sequential conduction circuit, and when working, the sequential conduction circuit loads voltage to each electrode pair one by one.
[0006] To further improve the technical solution, both the transverse needle strips and the longitudinal needle strips are composed of conductive strips and electrode probes, and the electrode probes are arranged equidistantly along the conductive strips.
[0007] To further improve the technical solution, an annular connecting piece is provided at one end of the conductive strip, and the sequential conducting circuit is connected to the connecting piece through an electric wire.
[0008] To further improve the technical solution, the length of the electrode probes on the longitudinal needle strips is greater than that of the electrode probes on the transverse needle strips, and the transverse needle strips and the longitudinal needle strips are spatially cross-arranged.
[0009] To further improve the technical solution, the distance between the two electrode probes on the electrode pair is 5-25 mm.
[0010] To further improve the technical solution, a plurality of fixing blocks are provided on the frame, wherein the fixing blocks have slots and threaded holes for fixing the interior trim panels.
[0011] After implementing the above technical solution, compared with the background technology, the beneficial effects produced by the utility model are:
[0012] From the above, it can be seen that the local subway station water leakage positioning device has a sponge board and an insulating board fixed in the frame, and horizontal needle strips and vertical needle strips are arranged on the insulating board to form a number of electrode pairs arranged in an array. When working, the sequential conduction circuit loads voltage to each electrode pair one by one, and the position of the wall leakage can be found and located by scanning row by row and column by column.
[0013] The subway station water leakage locating device can not only detect leakage in time and reduce the damage caused by leakage to the subway station, but also locate the location of the leakage and provide a reference for leakage repair. 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.
[0022] As attached Figure 1 As shown, a subway station water leakage positioning device includes a frame 1 fixed on the subway station wall for fixing the interior panel 4. A plurality of fixing blocks 8 are arranged on the frame 1, and the fixing blocks 8 have a card slot and a threaded hole, and the card slot and the threaded hole are used to fix the interior panel 4. The interior panel 4 is made of aluminum alloy, and the surface is spray-painted, which is decorative.
[0023] See attached Figure 2 A sponge board 2 and an insulating board 3 are fixed in the frame 1, wherein the sponge board 2 is attached to the wall. The sponge has good elasticity and water absorption. If water seeps from the wall, the leaking water will be absorbed by the sponge board 2, thereby making the water-absorbed sponge conductive.
[0024] The insulating board 3 is made of engineering plastic, and has horizontal pin strips 5 and vertical pin strips 6 arranged in an array on the insulating board 3. The insulating board 3 has two functions: one is to serve as a support to press the sponge board 2 against the wall; the other is that the insulating board 3 has insulation properties and is used to fix the horizontal pin strips 5 and the vertical pin strips 6.
[0025] See attached Figure 3 , the transverse needle bar 5 and the longitudinal needle bar 6 each have a plurality of equally spaced electrode probes 52. In this embodiment, there are six transverse needle bars 5 and twelve longitudinal needle bars 6, and both the transverse needle bars 5 and the longitudinal needle bars 6 are composed of conductive bars 51 and electrode probes 52, and the electrode probes 52 are equally spaced along the conductive bars 51. In order to facilitate the connection of the circuit, an annular connecting piece 53 is provided at one end of the conductive bar 51.
[0026] See attached Figure 2 and attached Figure 4 . The electrode probes 52 on the transverse needle strips 5 and the longitudinal needle strips 6 penetrate the insulating plate 3 and are inserted into the sponge plate 2 to form a plurality of electrode pairs 7 arranged in an array. The positions of the electrode pairs 7 can be described using a rectangular coordinate system. The anhydrous sponge plate 2 is an insulator. After the electrode pair 7 is loaded with voltage, no current will be generated between the two electrode probes 52. However, the sponge plate 2 containing water is conductive. After the electrode pair 7 is loaded with voltage, current will be generated between the two electrode probes 52. Generally, the distance between the two electrode probes 52 on the electrode pair 7 is 5-25 mm.
[0027] Refer to the attached Figure 5 In order to avoid cross short circuit, the length of the electrode probe 52 on the longitudinal needle bar 6 is greater than the length of the electrode probe 52 on the transverse needle bar 5. In this way, the transverse needle bar 5 and the longitudinal needle bar 6 are arranged in a spatially cross pattern.
[0028] Each transverse needle strip 5 and each longitudinal needle strip 6 is connected to the sequential conduction circuit through electric wires. When working, the sequential conduction circuit applies voltage to each electrode pair 7 one by one.
[0029] The sequential conduction circuit has a program chip, which can conduct each horizontal needle strip 5 in sequence, sequentially load a positive voltage with a certain time interval to each horizontal needle strip 5, and complete the longitudinal scanning of six horizontal needle strips 5 in one cycle, and its effect is similar to a marquee strip. Similarly, the sequential conduction circuit can conduct each vertical needle strip 6 in sequence, sequentially load a negative voltage with a certain time interval to each vertical needle strip 6, and complete the horizontal scanning of twelve vertical needle strips 6 in one cycle.
[0030] Refer to the attached Figure 6 For example, the sequential conduction circuit applies a negative voltage to the fifth longitudinal pin bar 6. At this time, the sequential conduction circuit performs a longitudinal scan on the six transverse pin bars 5. If the electrode pair 7 with a horizontal coordinate of 5 and a vertical coordinate of 3 (the position of the circle in the figure) generates a current when the third transverse pin bar 5 is applied with a positive voltage, it means that there is water leakage in the area where the electrode pair 7 is located, and the position of the wall leakage can be determined.
[0031] If no current is generated by the electrode pairs 7 on the fifth column in a vertical scanning cycle, it means that no leakage occurs in the area where the electrode pairs 7 on the fifth column are located. Then, the circuit is sequentially turned on to load a negative voltage on the sixth vertical needle strip 6, and then a vertical scan is performed on the six horizontal needle strips 5. This process is repeated until all electrode pairs 7 are scanned once.
[0032] It is worth noting that the sequential conduction circuit does not work for a long time, but works intermittently. For example, the sequential conduction circuit completes a scan of all electrode pairs 7 once a week, which can save energy and prevent accidents such as electric shock.
[0033] 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.
