Description

Technical Field

[0001] The invention relates to the technical field of auxiliary monitoring tools for power grid distribution stations, and in particular to a wall water seepage monitoring device for distribution stations. Background Art

[0002] In the urban power distribution network, distribution stations (substations, distribution rooms, switch stations, etc.) serve as the hubs and transfer stations of the power grid, and their number is increasing. Distribution stations are widely used in newly built communities and are often single-family buildings built by developers. After a long period of use, water seepage is prone to occur on the roofs and walls of distribution station buildings. The current robot autonomous inspection system in the station cannot monitor the water seepage. If the water seepage persists for a long time, on the one hand, it will affect the quality and safety of the building itself, and on the other hand, it will cause excessive humidity inside the distribution station, resulting in a decrease in the insulation level of the equipment, threatening the safe operation of the transformers and switch cabinets in the station. Therefore, it is particularly important to monitor and detect water seepage in a timely manner. However, the current anti-seepage issues on the roofs and walls of distribution station buildings are generally limited to active seepage tests performed by the engineering supervisor when the construction of the distribution station building is completed and accepted. For example, a Chinese patent document with authorization announcement number CN205300852U discloses a wall seepage test device, which uses a sprinkler pipe to spray water by setting a time, so that the supervisor can monitor the accurate waterproof ability of the wall. Similar public documents are also limited to tools for detecting the waterproof ability of the wall during project acceptance. However, there is no device that can monitor whether there is water seepage on the roof and walls of the distribution station building in real time during the long-term operation of the distribution station.

[0021] (Example 1)

[0022] See Figures 1 to 6 The distribution station wall water seepage monitoring device of this embodiment is mainly composed of a monitoring strip 1, a monitoring box 2 and a waterproof wire 3.

[0023] See also Figures 2 to 4The monitoring strip 1 is mainly composed of a water absorbing member 11, an insulating plate 12, a first conductive plate 13 and a second conductive plate 14. The water absorbing member 11 is composed of a water absorbing plate 11-1 and a water absorbing rib 11-2 in one piece. The water absorbing plate 11-1 is a long flat plate, and the water absorbing rib 11-2 is a long rectangular parallelepiped. The length of the water absorbing rib 11-2 in the left-right direction is less than the length of the water absorbing plate 11-1 in the left-right direction. The length of the water absorbing rib 11-2 is less than the length of the water absorbing plate 11-1. The water absorbing rib 11-2 is arranged on the front end surface of the water absorbing plate 11-1 and is located in the middle of the water absorbing plate 11-1 in the up-down direction. The water absorbing rib 11-2 is connected to the front end surface of the water absorbing plate 11-1 by its rear end surface. The water absorbing member 11 is made of a water-absorbing material such as a polymer material such as a water-absorbing resin. The insulating plate 12 is a plate member made of insulating material, the length and width of which match the water absorbing plate 11-1 of the water absorbing member 11. A water absorbing ridge through slot 12-1 which passes through in the front-to-back direction is provided in the middle of the insulating plate 12 along the length direction. The length and width of the water absorbing ridge through slot 12-1 match the water absorbing ridge 11-2 of the water absorbing member 11. The insulating plate 12 is fixedly arranged on the front end surface of the water absorbing plate 11-1 of the water absorbing member 11, and the water absorbing ridge 11-2 of the water absorbing member 11 extends forward after passing through the water absorbing ridge through slot 12-1 of the insulating plate 12. The first conductive plate 13 is a long strip of conductive copper sheet. The length of the first conductive plate 13 is less than the length of the insulating plate 12. The width of the first conductive plate 13 is less than the width from the upper end of the water absorbing edge 11-2 to the upper end of the insulating plate 12. The structure of the second conductive plate 14 is the same as that of the first conductive plate 13. The first conductive plate 13 and the second conductive plate 14 are both fixed on the insulating plate 12 and are respectively located at the upper and lower ends of the water absorbing edge 11-2 of the water absorbing member 11. The lower end of the first conductive plate 13 and the upper end of the second conductive plate 14 are both in close contact with the water absorbing edge 11-2 of the water absorbing member 11.

[0024] There are N monitoring strips 1 from the first to the Nth, where N is a natural number not less than 1. The number of monitoring strips 1 is determined according to the number of monitoring points on the wall of the distribution station where water seepage monitoring is required. Each monitoring strip 1 is fixedly arranged on the corresponding monitoring point on the wall of the distribution station in such a way that the rear end surface of the water absorbing plate 11-1 of the water absorbing member 11 is in close contact with the wall.

[0025] The monitoring box 2 is mainly composed of a box body 21, two mounting ears 22 fixed on the box body 21, and a circuit device. The circuit device includes an antenna 4 and a buzzer 5 fixed on the box body 21, and a circuit board (not marked in the figure) fixed in the box body 21. The circuit board is provided with N signal trigger modules (referred to as the first signal trigger module, the second signal trigger module, and the Nth signal trigger module, respectively) the same number as the monitoring strips 1, a single-chip computer module, a wireless communication module, and a power supply module. Each signal trigger module is electrically connected to the single-chip computer module, the wireless communication module is communicatively connected to the single-chip computer module, the antenna 4 is communicatively connected to the wireless communication module, and the buzzer 5 is electrically connected to the single-chip computer module. Each signal trigger module is electrically connected to the first conductive plate 13 and the second conductive plate 14 on a corresponding monitoring strip 1 through two waterproof wires 3. The power supply module is used to provide working power for the monitoring device. The power supply module can be powered by a battery or by a DC power supply of an automation terminal in a distribution station. After voltage conversion, it provides working power for the monitoring device. It should be noted that the signal trigger module, single-chip computer module, wireless communication module and power module itself, electrical connection relationship and working principle on the circuit board are all mature existing technologies and will not be described in detail.

[0026] See also Figure 6 For example, as an implementation method, the first signal trigger module, the second signal trigger module, and the Nth signal trigger module can respectively use resistors R1, R2, ... RN. When in use, each monitoring strip 1 is functionally equivalent to a normally open switch K1, K2, ... KN when there is no water seepage at the monitoring point of the distribution station wall.

[0027] The working principle of the water seepage monitoring device for the distribution station wall of this embodiment is briefly described as follows:

[0028] During the use of the distribution station wall water seepage monitoring device of the present embodiment after installation, if water seepage occurs in the distribution station wall where the monitoring strip 1 at a certain monitoring point is installed, the water absorbing member 11 of the monitoring strip 1 in close contact with the wall, which is made of a water absorbing plate 11-1 made of a water absorbing material, begins to absorb water and penetrates into the water absorbing edge 11-2. When the water absorbed by the water absorbing edge 11-2 reaches the conductive critical point, the first conductive plate 13 and the second conductive plate 14 of the monitoring strip 1 are electrically connected, which is equivalent to the following example. Figure 6 When the corresponding normally open switch K shown is closed, the voltage of the corresponding port of the single-chip microcomputer module changes. The single-chip microcomputer module can determine that water seepage occurs in the wall of the distribution station monitored by the monitoring strip 1 according to the voltage change of the corresponding port. On the one hand, the single-chip microcomputer module uses the existing communication network through the wireless communication module and the antenna 4 to remotely send a water seepage alarm signal to the equipped monitoring background. On the other hand, the single-chip microcomputer module controls the buzzer 5 to sound an on-site alarm, thereby realizing real-time monitoring of water seepage in the distribution station wall.

[0029] The above embodiments are descriptions of specific implementation methods of the present invention rather than limitations of the present invention. Technical personnel in the relevant technical field can make various changes and modifications to obtain corresponding equivalent technical solutions without departing from the spirit and scope of the present invention. Therefore, all equivalent technical solutions should be included in the patent protection scope of the present invention.
