Description

Technical Field

[0001] The present application relates to the field of substation protection equipment, and in particular to a substation rain leakage monitoring device. Background Art

[0002] A substation is a collection of equipment used to connect or disconnect, change, or adjust voltage. In the power system, a substation is the hub for power transmission and distribution. Substations are primarily categorized as step-up substations, main grid substations, secondary substations, and distribution substations. As substations age, their roofs are prone to aging waterproofing or clogged drainage pipes. This can lead to rooftop waterlogging and leakage during the summer flood season, potentially causing short circuits in electrical equipment and adversely impacting the stable operation of the power system.

[0003] At present, we mainly rely on daily inspections to check the roof's waterproof layer, drainage pipes and other places where there may be leaks. When the waterproof layer is damaged or the sewer pipe is blocked, we deal with it in a timely manner. In addition, special inspections for leaks are carried out during and after rains to increase the frequency of inspections, thereby reducing or avoiding the occurrence of leaks.

[0004] However, such inspections are less efficient and require inspectors to spend more time and energy. Moreover, when a small amount of roof leakage occurs, the rainwater will flow along the structure of the house, causing the rainwater to not fall directly below the leak, thereby reducing the inspectors' efficiency in locating the leak. Summary of the Invention

[0005] In order to improve the low efficiency of manual inspection, this application provides a substation leakage monitoring device, which adopts the following technical solutions:

[0006] A substation rain leakage monitoring device comprises a water retaining bar and a water leakage point indicating mechanism arranged at intervals on the water retaining bar; the water retaining bar is arranged on the walls around the substation and is located below the roof, the vertical cross-section of the water retaining bar is L-shaped, the horizontal end side walls of the water retaining bar are connected to the wall, and a water flow channel is formed between the vertical end side walls of the water retaining bar and the wall; the water leakage point indicating mechanism comprises a water collecting pipe, the top of the water collecting pipe is connected to the water flow channel, and the bottom of the water collecting pipe is connected to a cover body that performs a sealing function via a magnet.

[0007] By adopting the above technical solution, when the leaking point of the roof is small, the rainwater flows down to the wall through the slope of the roof, and then flows down from the wall. Since the water retaining strips are arranged on the walls around the substation, the rainwater will be blocked by the water retaining strips in the process of flowing down along the wall and collected in the water flow channel of the water retaining strips. When the leaking rainwater is large, the rainwater will form a flowing water flow in the water flow channel. When the water flows into the water collecting pipe and gathers in the water collecting pipe, the pressure on the cover body gradually increases, and the magnetic connection between the cover body and the water collecting pipe will fail, and the cover body will separate from the water collecting pipe. In this way, By observing the connection status of the relatively large water collection pipe and the cover, the inspection personnel can find the flow position of rainwater on the wall, and then find the leakage point of the roof in reverse according to the traces of rainwater on the wall. This can increase the speed of locking the leakage point and avoid the need to conduct a comprehensive inspection of all positions during each inspection. It greatly improves the inspection efficiency, facilitates the rapid repair of leakage points, and prevents the leakage point from becoming larger, so that rainwater can directly enter the substation and cause a short circuit in electrical equipment; when the leakage point becomes larger, the inspection personnel can quickly find the leakage point by observing the water column formed by rainwater and the sound of the water column hitting the ground.

[0008] Optionally, the water leakage point indicating mechanism further includes a telescopic tube that can extend in the vertical direction, the top of the telescopic tube is connected to the outer wall of the water collecting pipe, and the bottom of the telescopic tube is connected to the outer wall of the cover body.

[0009] By adopting the above technical solution, after the water flows into the water collecting pipe and the cover body is separated from the water collecting pipe, the bottom of the telescopic tube will move downward with the cover body, causing the telescopic tube to stretch, which can prevent the water from floating around after the sealing effect of the cover body on the water collecting pipe is released, causing damage to electrical equipment. In other words, after the cover body is separated from the water collecting pipe, the telescopic tube will stretch, keeping the leakage point indication mechanism as a semi-closed whole, and the overall length of the leakage point indication mechanism will be extended under the elongation of the telescopic tube, which is convenient for inspection personnel to observe and locate, and the sealing effect of the telescopic tube can prevent water from overflowing and causing short circuit in electrical equipment, and has a certain protective effect.

[0010] Optionally, a compressed cotton strip is provided in the water collecting pipe, and the compressed cotton strip absorbs rainwater in the water flow channel and expands to push the cover body.

[0011] By adopting the above technical solution, after the water flows into the water collection pipe, it will first be absorbed by the compressed cotton strips. After absorbing water, the compressed cotton strips will expand. After the volume gradually increases, the compressed cotton strips will form a pushing effect on the cover body. After the compressed cotton strips absorb a sufficient amount of water and produce a sufficient degree of expansion, the compressed cotton strips will push the cover body to overcome the attraction of the magnet, thereby separating the cover body from the water collection pipe, thereby increasing the overall length of the leakage point indicator mechanism, which is convenient for inspection personnel to observe. Moreover, through the adsorption effect of the compressed cotton strips, the accumulation of water in the water collection pipe can be reduced or even avoided, thereby preventing a large amount of water from gushing out when the cover body is separated from the water collection pipe, causing damage to electrical equipment.

[0012] Optionally, a limiting plate is further provided in the water collecting pipe, and a plurality of water-permeable holes are provided on the top of the limiting plate, and the plurality of water-permeable holes are located above the compressed cotton strips.

[0013] By adopting the above technical solution, a limiting effect is exerted on the expansion direction of the compressed cotton strips, preventing the compressed cotton strips from extending from the top of the water collection pipe and causing insufficient pushing force on the cover body. That is to say, by setting a limiting plate with a plurality of water-permeable holes, it is ensured that the water flow can smoothly enter the water collection pipe and be absorbed by the compressed cotton strips, thereby promoting the expansion of the compressed cotton strips. It can also make the compressed cotton strips expand only toward the bottom of the water collection pipe, so that the compressed cotton strips have enough thrust to push the cover body and the water collection pipe to separate after absorbing less water flow. In this way, the leakage point can be indicated within a short time after the leakage occurs, thereby improving the inspection efficiency.

[0014] Optionally, a convex strip is provided on the inner wall of the water collecting pipe, and the convex strip is used to clamp the compressed cotton strip in the horizontal direction.

[0015] By adopting the above technical solution, when no water leakage occurs, the convex strips can tighten the compressed cotton strips, ensuring that when water flows into the water collection pipe and the compressed cotton strips begin to absorb water, the compressed cotton strips remain in a vertically extended state, ensuring that the compressed cotton strips can form a reliable pushing effect on the cover body after expansion.

[0016] Optionally, there is a distance between the top of the limiting plate and the top of the water collecting pipe, forming a water storage space.

[0017] By adopting the above technical solution, the compressed tampon can absorb water and expand more smoothly and evenly.

[0018] Optionally, a water sensor is provided at the inner bottom of the cover body. After the water sensor collects a water leakage signal, it transmits it to the controller through a signal line. The controller controls the first warning light to be in a constantly on state.

[0019] By adopting the above technical solution, when the water flows into the water collecting pipe and the compressed cotton strips begin to absorb water, a small amount of water droplets will fall onto the cover body. When the water contacts the water immersion sensor, the water immersion sensor will transmit the signal that there is water on the cover body to the controller, and then the controller will transmit the working instruction to the first warning light through the signal line, so that the first warning light is always on. Since the compressed cotton strips are still in the early stage of absorbing water and expanding, the leakage point has not yet caused damage. After the inspection personnel see that the first warning light is always on, there is still sufficient time to carry out relevant preparations; moreover, through the response of the receiving end of the controller, the position of the leakage point indication mechanism where there is a leakage phenomenon can be quickly determined, remote inspection can be realized, and the inspection efficiency can be further improved.

[0020] Optionally, a pressure sensor is further provided at the inner bottom of the cover body. After the pressure sensor collects the pressure value signal, it is transmitted to the controller through the signal line. The controller controls the second warning light to be in a flashing state and the flashing frequency changes synchronously with the pressure value.

[0021] By adopting the above technical solution, when the compressed cotton strips continue to absorb water and expand, forming a pushing effect on the cover body, the compressed cotton strips will also form a downward pressure on the pressure sensor. The pressure sensor transmits the pressure value signal to the controller through the signal line, and then the controller transmits the work instruction to the second warning light through the signal line, causing the second warning light to flash. As the amount of water absorbed by the compressed cotton strips increases, the downward pressure of the compressed cotton strips on the pressure sensor also becomes greater and greater, and the pressure value signal collected by the pressure sensor becomes larger. The controller will process this signal and control the flashing frequency of the second warning light to gradually increase. In this way, the inspection personnel can judge the water absorption and expansion of the compressed cotton strips by paying attention to the flashing frequency of the second warning light, thereby speeding up the determination and compensation of the leakage point.

[0022] Optionally, the water retaining strip is wavy, and the water leakage point indicating mechanism is located at the trough of the water retaining strip.

[0023] By adopting the above technical solution, rainwater flows downward along the wall, and after coming into contact with the water retaining bar, it will move along the water flow channel of the water retaining bar toward the trough of the water retaining bar, thereby improving the guiding effect on the water flow, preventing the water flow from accumulating in one place in the water flow channel and directly overflowing the water retaining bar, ensuring that the water retaining effect of the water retaining bar is reliable, and the leakage point indication mechanism has a reliable indication effect on the leakage point.

[0024] Optionally, a water diversion groove is provided on the upper wall of the horizontal end of the water retaining bar, and the laying direction of the water diversion groove is consistent with that of the water retaining bar. A plurality of accommodating holes are provided at intervals at the bottom of the water diversion groove, and the accommodating holes are filled with anhydrous copper sulfate powder.

[0025] By adopting the above technical solution, when water flows in the water flow channel, it will preferentially flow in the water diversion trough, further reducing the possibility of water overflowing the water retaining bar. Moreover, the water will pass through the receiving holes in the water diversion trough and come into contact with the anhydrous copper sulfate powder, causing the anhydrous copper sulfate to absorb water and change color. In this way, by observing the position of the receiving hole where the anhydrous copper sulfate changes color, the landing point of the rainwater on the water retaining bar can be found, thereby determining the location of the leakage point.

[0026] In summary, this application has the following beneficial effects:

[0027] 1. Rainwater will form a flowing water flow in the water flow channel. When the water flows into the water collecting pipe and gathers in the water collecting pipe, the cover body and the water collecting pipe will separate from each other. During the separation process, the telescopic tube connected to the water collecting pipe and the cover body will also be in an extended state. In this way, the overall external length of the leakage point indication mechanism will become longer, which is convenient for direct observation from the outside, so as to determine the approximate location of the leakage point. Then, by observing the position near the leakage point indication mechanism that produces volume change, the specific location of the leakage point can be determined. During the inspection process, it is only necessary to observe the leakage point indication mechanism that produces volume change to determine the location of the leakage point by reverse search, thereby effectively improving the inspection efficiency.

[0028] 2. By arranging compressed cotton strips in the water collecting pipe, the compressed cotton strips will expand vertically after absorbing water, and form a pushing effect on the cover body. While being able to reliably push the cover body to separate from the water collecting pipe, it can reduce or even avoid the accumulation of water in the water collecting pipe, thus preventing a large amount of water from gushing out when the cover body is separated from the water collecting pipe, causing damage to electrical equipment.

[0029] 3. By setting a pressure sensor and a water immersion sensor in the cover, the water absorption status of the compressed cotton strip is detected, and the degree of water leakage is reflected by the different lighting states of the first warning light and the second warning light, which is convenient for inspection personnel to adjust their work progress.

[0038] The following is combined with Figure 1-7 This application is described in further detail.

[0039] Figure 1 This is a schematic diagram of the installation location of this application. Figure 2 It is a schematic three-dimensional diagram of the water retaining bar in this application. Figure 1 and Figure 2 A substation leakage monitoring device includes a water retaining bar 1 and a leakage point indicating mechanism 2. The water retaining bar 1 is arranged in a wavy ring on the walls 3 around the substation and is located below the roof 4. Multiple leakage point indicating mechanisms 2 are respectively and one-to-one correspondingly arranged at the troughs of the water retaining bar 1. The vertical cross-section of the water retaining bar 1 is L-shaped. The horizontal end side wall of the water retaining bar 1 is connected to the wall 3, and a water flow channel 11 is formed between the vertical end side wall of the water retaining bar 1 and the wall 3.

[0040] Figure 3 This is a schematic top view of the water leakage point indicating mechanism 2 in this application. Figure 3 The leakage point indicating mechanism 2 includes a water collecting pipe 21, a cover body 23, a telescopic tube 24 and a compressed cotton strip 25. A limiting plate 26 is provided on the top of the water collecting pipe 21 and is connected to the water flow channel 11. The water collecting pipe 21 and the cover body 23 are connected by a magnet 22. The telescopic tube 24 is sleeved on the outside of the water collecting pipe 21 and the cover body 23 and wraps the connection between the water collecting pipe 21 and the cover body 23. The compressed cotton strip 25 absorbs water and expands, and under the limiting action of the limiting plate 26, pushes the cover body 23 downward to separate the cover body 23 from the water collecting pipe 21. After the cover body 23 is separated from the water collecting pipe 21, the inspection personnel can determine the approximate location of the leakage point by ensuring the position of the water collecting pipe 21 without the cover body 23. By observing the water flow state at this position, the location of the leakage point on the roof 4 of the substation can be determined.

[0041] Figure 4 It is along Figure 3 A schematic cross-sectional view taken along the cutting line AA in FIG. Figure 5 yes Figure 4 Action state reference Figure 1 See also Figure 4 and Figure 5 , rainwater will form a flowing water flow in the water flow channel 11. When the water flows into the water collecting pipe 21, it will be absorbed by the compressed cotton strips 25. The compressed cotton strips 25 will push the cover body 23 after absorbing water and expanding, so that the magnetic connection between the cover body 23 and the water collecting pipe 21 will be invalid, thereby causing the cover body 23 to separate from the water collecting pipe 21. After the cover body 23 is separated from the water collecting pipe 21, the bottom of the telescopic tube 24 will move downward with the cover body 23. In this way, the telescopic tube 24 will extend and always wrap the bottom of the water collecting pipe 21 and the top of the cover body 23, ensuring that the water flow in the leak point indicator mechanism 2 will not flow out. Then, through the overall extension of the leak point indicator mechanism 2, it is convenient for the inspection personnel to find the flow position of rainwater on the wall 3, and then find the leak point position of the roof 4 in reverse according to the traces of rainwater on the wall 3, which can increase the speed of locking the leak point, avoid the need to conduct a comprehensive inspection of all positions every time for inspection, and greatly improve the inspection efficiency.

[0042] Figure 6 yes Figure 2 Schematic partial enlarged view of point B in the figure. Figure 6 A water diversion groove 12 is provided on the upper wall of the horizontal end of the water retaining bar 1. The water diversion groove 12 is consistent with the laying direction of the water retaining bar 1. A plurality of accommodating holes 120 are provided at intervals at the bottom of the water diversion groove 12. The accommodating holes 120 are filled with anhydrous copper sulfate powder. After the water flows through the water diversion groove 12, it can flow smoothly in the water flow channel 11. When the water flows in contact with the anhydrous copper sulfate, the anhydrous copper sulfate will produce a color change effect. In this way, by observing the position corresponding to the anhydrous copper sulfate producing the color change effect, the position where the rainwater falls into the water flow channel 11 can be found. Then, the position of the water leak can be determined by moving upward along the wall 3, which significantly improves the inspection efficiency.

[0043] Figure 7 yes Figure 4 Action state reference Figure 2 See also Figure 6 and Figure 7A water immersion sensor 28 and a pressure sensor 29 are provided at the inner bottom of the cover body 23. The water immersion sensor 28 is connected to the receiving end of the controller through a signal line, and the pressure sensor 29 is connected to the receiving end of the controller through a signal line. The sending end of the controller sends working instructions to the first warning light and the second warning light respectively through the signal line. When the water just flows into the water collecting pipe 21, most of it will be absorbed by the compressed cotton strips 25, and a small part will penetrate downward and fall directly on the cover body 23. When this small part of the water flows into the water immersion sensor 28, the water immersion sensor 28 will collect the water immersion signal and transmit it to the controller through the signal line. The controller then controls the first warning light to be in a constant light state. In this way, it can effectively remind the patrol personnel that there is water flow in the leakage point indication mechanism 2 at the current position, so there is a leakage point near the position, and the patrol personnel need to check it. Since the water flow has just been formed and started to flow to the water collecting pipe 21 at this time, the patrol personnel have a longer time to check and make up for the leakage point; when the amount of water flowing into the water collecting pipe 21 is large, the compressed cotton strips 25 will produce a large amount of expansion and push the cover body 23 and the pressure sensor 29. Since the compressed cotton strips 25 continue to absorb water, the pressure generated by the compressed cotton strips 25 on the cover body 23 and the pressure sensor 29 gradually increases, and the pressure sensor 29 transmits the collected pressure value signal that is gradually increasing to The controller controls the second warning light to flash and the flashing frequency gradually increases. In this way, it can remind the patrol personnel that the water content in the water leakage point indication mechanism 2 at the current location is relatively large, and the water leakage point needs to be checked and repaired as soon as possible; further, after the compressed cotton strip 25 pushes the cover body 23 to separate from the water collection pipe 21, the pressure on the pressure sensor 29 is instantly reduced, and the pressure sensor 29 transmits the corresponding signal to the controller. The controller reduces the flashing frequency of the second warning light or keeps the second warning light always on. In this way, when the flashing frequency of the second warning light is reduced from high, the patrol personnel need to reach the scene immediately for processing. That is to say, through the collection and transmission of water immersion signals and pressure signals by the water immersion sensor 28 and the pressure sensor 29, the different lighting states of the first warning light and the second warning light are realized, so that the location of the water leakage point can be indicated while guiding the patrol personnel to process the water leakage point at different speeds. It has a high degree of intelligence and can effectively prompt the work efficiency of the patrol personnel and optimize the work arrangements of the patrol personnel.

[0044] The working principle of the present application when in use is as follows: when the leaking point of the roof 4 is small, rainwater flows down to the wall 3 through the slope of the roof 4, and then flows downward from the wall 3 into the water flow channel 11. Since the water retaining strip 1 is wavy, the water flow will follow the trough of the water retaining strip 1 and be collected in the water collecting pipe 21. A compressed cotton strip 25 is provided in the water collecting pipe 21. The compressed cotton strip 25 will expand vertically after absorbing water, forming a pushing effect on the cover body 23, so that the cover body 23 overcomes the attraction of the magnet 22 and separates from the water collecting pipe 21. In the process of separation of the two, the telescopic tube 24 is extended accordingly. In this way, the overall length of the leaking point indicator mechanism 2 will be extended. The inspection personnel can quickly lock the approximate position of the leaking point through the change of the leaking point indicator mechanism 2, and determine the position of the leaking point by the flow of water in the water channel, avoiding full-range inspection and significantly improving the inspection efficiency.

[0045] Secondly, by collecting and transmitting water immersion signals and pressure signals through the water immersion sensor 28 and the pressure sensor 29, different lighting states of the first warning light and the second warning light can be realized, thereby indicating the location of the leakage point and guiding the inspection personnel to deal with the leakage point at different speeds. It has a high degree of intelligence and can effectively improve the work efficiency of the inspection personnel and optimize the work arrangements of the inspection personnel.

[0046] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
