[0022] The technical solutions in the embodiments of the present application will be described clearly and completely in the following with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, but not all the embodiments. Based on the embodiments in the present application, all the other embodiments obtained by those skilled in the art without creative labor are within the protection scope of the present application.

[0023] In order to make the technical personnel in the art better understand the present application, the present application will be further described in detail below with reference to the drawings and specific embodiments.

[0024] Please refer to Figure 1 , Figure 1 The function module diagram of the underground water accumulation emergency system provided by the embodiments of the present application.

[0025] The present application provides an underground water accumulation emergency system, comprising an underground pipe gallery, a water pump arranged in the underground pipe gallery and a plurality of water accumulation sensors arranged in the underground pipe gallery; wherein the underground pipe gallery penetrates downward from the ground surface and can comprise a primary operation room and a secondary operation room which are connected with each other, the primary operation room and the secondary operation room are both located below the ground surface, and the primary operation room is lower than the secondary operation room; in view of the foregoing structural features of the underground pipe gallery, the water accumulation sensors of the underground water accumulation emergency system comprise a plurality of water accumulation sensors I arranged in the primary operation room and a plurality of water accumulation sensors II arranged in the secondary operation room.

[0026] The underground water accumulation emergency system, all water accumulation sensors I are dispersed in the first operation room, and all water accumulation sensors II are dispersed in the second operation room; the water pump comprises a water suction port communicated with the first operation room, and a water discharge port of the water pump can be above the ground surface or arranged at a specified water discharge position below the ground surface. In the underground water accumulation emergency system, the water pump can adjust the water pumping power according to the water accumulation amount and the water accumulation height fed back by all water accumulation sensors.

[0027] According to the distribution characteristics of all water accumulation sensors I and all water accumulation sensors II in the underground pipe gallery, in the embodiment, all water accumulation sensors I can reasonably monitor and feed back the water leakage phenomenon and the water accumulation degree in the first operation room, and all water accumulation sensors II can reasonably monitor and feed back the water leakage phenomenon and the water accumulation degree in the second operation room.

[0028] In the underground water accumulation emergency system, the first operation room and the second operation room are communicated with each other, and the first operation room is lower than the second operation room, therefore, the water accumulation phenomenon of the second operation room also reflects the water accumulation severity in the entire underground pipe gallery, and correspondingly, the water accumulation amount fed back by all water accumulation sensors mentioned above can be roughly divided into the following cases: no water accumulation in the first operation room, water accumulation only in the first operation room, water accumulation in the second operation room after the first operation room is overfilled, and the water accumulation severity in the foregoing cases increases. Therefore, the water pumping power of the water pump is adjusted according to the water accumulation amount and the water accumulation height fed back by all water accumulation sensors, which means that the water pumping power is increased when the water accumulation amount and the water accumulation height in the underground pipe gallery are large, and the water pumping power is decreased when the water accumulation amount and the water accumulation height in the underground pipe gallery are small.

[0029] When individual water accumulation sensors of the first operation room or the second operation room obtain water accumulation signals, it may be caused by the leakage of production water of the first operation room or the second operation room, failure of the check valve of the drainage pump, etc., at this time, the underground water accumulation emergency system automatically starts the water pump to drain the position where the water accumulation sensor is located.

[0030] When multiple water accumulation sensors or even all water accumulation sensors of the first operation room or the second operation room obtain water accumulation signals at the same time, it may be caused by a large leakage of the first operation room or the second operation room due to pipe burst of the water supply pipeline, at this time, in addition to automatically adjusting the water pumping power of the water pump and shutting down the water supply pump and the valve at the corresponding position, the underground water accumulation emergency system can also realize auxiliary emergency protection by the site staff, such as the water level of the water supply tank connected with the water supply pump.

[0031] When the valve of the underground pipe gallery is shut down, the pipeline, container or water tank near the valve can be emptied and depressurized to prevent the valve from continuing to leak due to the failure of the long-term sealing property, thereby causing the continuous spread of the accident.

[0032] The underground water accumulation emergency system can be provided with one or more water pumps, and thus, for multiple water pumps, the water pumping power refers to the total power, which means that the total power can be increased by increasing the actual working power of a single water pump or by increasing the number of water pumps in the open state. When the underground water accumulation emergency system is provided with multiple water pumps, different types of water pumps can be configured according to the specific topographic conditions in the primary operation room and the secondary operation room. For example, in an area with high and flat terrain, a large sewage pump can be configured as the aforementioned water pump, which is used for emergency drainage, and the power supply control of the large sewage pump is led to the ground to prevent water flooding short circuit; in a low-lying area, a small sewage pump can be configured, and the power supply of the small sewage pump is integrated with the pump body, which can be understood as the integration of the pump body and the power supply of the small sewage pump.

[0033] The underground water accumulation emergency system provided by the present application has an emergency protection function, and can be used as an auxiliary detection system for underground flood control projects of factories near mountains and coastal areas.

[0034] The water accumulation emergency system can monitor the primary operation room and the secondary operation room all day round, and the monitoring coverage area is wide, which is beneficial to eliminate the adverse factors of manual inspection not in time, reduces the labor intensity of the workers and the probability of exposure to the risk area, improves the reliability of accident prevention, so that emergency protection can be taken in time and effectively when the primary operation room and the secondary operation room have water leakage and water accumulation, and the risk and loss are reduced.

[0035] The underground water accumulation emergency system provided by the present application will be further described below in combination with the drawings and embodiments.

[0036] For the layout mode of multiple water accumulation sensors in the primary operation room and the secondary operation room, the following will be illustrated by taking the primary operation room as an example.

[0037] When the primary operation room is a pipeline room, a plurality of water pipes are arranged in the pipeline room, and thus, the reasons for water leakage in the primary operation room include water leakage caused by the aforementioned water pipes and other reasons. In order to more sensitively and accurately detect the water leakage in the primary operation room, the water accumulation sensor I includes a water accumulation sensor I-I arranged close to the water pipe distribution of the primary operation room; in order to reasonably detect the water accumulation degree of the primary operation room, the water accumulation sensor I further includes a water accumulation sensor I-II arranged around the ground of the primary operation room. In addition, a plurality of water accumulation sensors I-III can be further arranged at different heights of the primary operation room, which can detect and analyze the water accumulation height in the primary operation room in cooperation with all the water accumulation sensors I-II.

[0038] When the primary operation room is an electrical room, the electrical room is provided with an electrical cabinet and various electrical components installed on the electrical cabinet. In order to ensure the safe operation of the electrical cabinet and various electrical components therein, the total water sensor I includes a water sensor I-I-I distributed close to the electrical cabinet of the primary operation room, which is used to monitor whether the electrical cabinet is affected by the surrounding water leakage points or accumulated water; in order to reasonably detect the water level in the primary operation room, the water sensor I further includes a water sensor I-I-II arranged around the ground of the primary operation room. In addition, a plurality of water sensors I-I-III can be further arranged at different heights in the primary operation room, which can detect and analyze the water level in the primary operation room in cooperation with the total water sensor I-I-II.

[0039] When the electrical room as the primary operation room has a serious water accumulation phenomenon, measures such as stopping production in the primary operation room, cutting off the low-voltage power supply on site, and switching to emergency power supply can be taken.

[0040] Further, the underground water emergency system further includes a dispatching room provided with a console; the dispatching room can be arranged below the ground surface or above the ground surface; the console is provided with a plurality of signal displays, which are connected one by one with the total water sensor. When the water sensor changes in voltage due to water leakage or water accumulation, the signal display connected with the water sensor sends a signal to remind and inform the staff in the dispatching room of the water leakage and water accumulation in the underground pipe gallery, and urge and dispatch the on-duty personnel to check and confirm on site when the underground pipe gallery has a water accumulation phenomenon; when the water accumulation in the underground pipe gallery is serious, the staff in the dispatching room can intervene in the emergency operation of the underground water emergency system in time, for example, flexibly dispatching personnel in the factory to manually adjust the working state of each component in the underground pipe gallery.

[0041] The above-mentioned dispatching room can further include an alarm system, a drainage system, a gateway, a server, a human-computer interface, etc. The alarm system, for example, a distributed sound and light alarm unit, sends a sound and light alarm according to the water detection signal of the total water detector. The gateway is connected to the total water detector, which is used to convert the water detection signals scattered in the underground pipe gallery obtained by the total water detector into network signals, and uniformly transmit them to the same network. The signal display is integrated into the human-computer interaction interface, which is convenient for the staff in the dispatching room to monitor and control the working state of the underground pipe gallery. The water sensor can be connected to the aforementioned dispatching room through the liquid level controller and the signal conversion unit.

[0042] On the basis of the above-mentioned embodiments, the underground water accumulation emergency system further comprises a camera arranged in the first operation room and the second operation room respectively; the camera is connected with the dispatching room; the camera acquires image information in the first operation room and the second operation room and transmits the image information to the dispatching room, which on one hand assists the monitoring of the underground pipe gallery by the water leakage sensors, and on the other hand can monitor and feedback the running state of various equipment and the location of the staff in the underground pipe gallery in real time.

[0043] In addition, in the underground water accumulation emergency system, a water supply pipeline, a manual cut-off valve and / or an electric valve connected with the water supply pipeline are arranged in the first operation room; if the water supply pipeline is provided with the electric valve, a relay connected with the electric valve is arranged in the dispatching room.

[0044] The manual cut-off valve can be manually controlled by the staff in the first operation room, and when the first operation room fails and needs to shut down the water supply pipeline, the water supply pipeline can be quickly cut off to avoid the water in the water supply pipeline continuing to flow.

[0045] The electric valve can be remotely controlled in combination with the relay, and when the first operation room fails and needs to shut down the water supply pipeline, the staff in the dispatching room can remotely cut off the water supply pipeline.

[0046] The dispatching room used in the present application can include a dispatching room I and a dispatching room II. The console of the dispatching room I is provided with a signal display I connected with all the water accumulation sensors I one by one; the console of the dispatching room II is provided with a signal display II connected with all the water accumulation detectors I and all the water accumulation detectors II one by one. In other words, the dispatching room I corresponds to the first operation room, and the staff in the first operation room can only monitor the state in the first operation room; the dispatching room II corresponds to the second operation room, and the staff in the second operation room can only monitor the state in the second operation room. Obviously, the dispatching room I and the dispatching room II belong to the same level control center.

[0047] In addition to setting the dispatching room as the dispatching room I and the dispatching room II at the same level, the dispatching room can also be set at different levels, which can realize hierarchical management and control for different risk levels of hidden dangers, is convenient for centralized monitoring, prevents monitoring negligence of team personnel, and better utilizes the resources of the general plant to realize rapid emergency.

[0048] For example, dispatching room II is a superior control center of dispatching room I. At this time, the console of dispatching room I is provided with signal display I connected with all water sensor I one by one; the console of dispatching room II is provided with signal display II connected with all water sensor II one by one and signal display III connected with dispatching room I. In short, dispatching room I displays the status in first level operation room by signal display I, dispatching room II can display the status in second level operation room by signal display II or the status in first level operation room by signal display III.

[0049] The underground water emergency system provided by the present application is described in detail above. The principle and implementation mode of the present application are described by applying specific examples in this paper, and the above description of the examples is only used to help understand the method of the present application and its core idea. It should be pointed out that, for ordinary skilled persons in the technical field, some improvements and modifications can be made to the present application without departing from the principle of the present application, and these improvements and modifications also fall within the protection scope of the claims of the present application.
