The intelligent drainage system provided by the embodiment of the present application is described in detail through specific embodiments and application scenarios thereof with reference to the accompanying drawings.

As shown in fig. 1 to 2, an embodiment of the present application provides an intelligent drainage system, which may include a first controller 110, a level gauge 120, a drainage pump 130, and a shut valve 140.

The first controller 110 may control other devices of the intelligent drainage system so that the other devices may operate at a specific time or under a specific condition. The first controller 110 may obtain data on other devices, and may store, operate and analyze the obtained data to obtain corresponding results, and may control the other devices to execute corresponding commands according to the obtained results. The first controller 110 may be combined with various functional modules to form a bus-mode FCS architecture, and the first controller 110 itself may have a powerful Web monitoring management function to support multi-bus monitoring. The plurality of first controllers 110 may form a decentralized management mode, form centralized monitoring control of a distributed system through a wired and/or wireless network, and form a powerful monitoring network with centralized monitoring cloud platform software. In addition, the system can also form small-sized area monitoring with other extended function modules, and the networking mode is flexible and diverse, thereby being capable of meeting various large, medium and small-sized monitoring and controlling requirements. The first controller 110 may be a Programmable Logic Controller (PLC) or other type of controller, which is not limited in this embodiment.

The level gauge 120 is electrically connected to the first controller 110, the level gauge 120 is configured to be disposed in the first reservoir 300, and the level gauge 120 is configured to obtain a first measurement value of the first reservoir 300. The liquid level gauge 120 may be a buoyancy-type liquid level gauge, which may vary with the liquid level, so that the level of the accumulated water in the first reservoir 300 may be measured, that is, the first measurement value may refer to the height of the accumulated water in the first reservoir 300.

The drain pump 130 is electrically connected to the first controller 110, and the first controller 110 can control the start and stop of the drain pump 130 to enable the drain pump 130 to drain water or stop draining water. The drain pump 130 is configured to be disposed in the first water reservoir 300, and the first water reservoir 300 may be located in a park or a residential area, or may be located outside the park or the residential area. The first water reservoir 300 is communicated with the first drainage well 500 through the overflow pipe 400, and the first drainage well 500 may be located in a garden or a residential area. The first drainage well 500 communicates with the second drainage well 700 through the first drainage pipe 600, and the second drainage well 700 may be a municipal drainage well. The second drain well 700 communicates with the drain pump 130 through the second drain pipe 800. The accumulated water in the garden or residential dwelling may flow through the first drainage well 500 to the second drainage well 700 for drainage. When the accumulated water in the first drainage well 500 reaches a certain height, the accumulated water may flow into the first reservoir 300 through the overflow pipe 400, and at this time, the stop valve 140 is closed.

The cut-off valve 140 is electrically connected to the first controller 110, and the cut-off valve 140 is disposed in the first drain pipe 600. The shut-off valve 140 may be an electrically controlled valve, and the shut-off valve 140 may be disposed in the valve well 900.

In case the first measurement value is smaller than the first preset threshold value, the first controller 110 turns off the drain pump 130 and turns on the cut-off valve 140; in case the first measurement value is greater than the second preset threshold value, the first controller 110 activates the drain pump 130 and closes the cut-off valve 140. The second preset threshold may be greater than or equal to the first preset threshold, which is not limited in the embodiment of the present application.

In the present embodiment, the level gauge 120 measures the water level in the first reservoir 300 to obtain a first measurement value. In case that the first measured value is less than the first preset threshold value, the first controller 110 turns off the drain pump 130 and turns on the cut-off valve 140, that is, the drain pump 130 stops working, and the first drain pipe 600 is turned on, so that the accumulated water in the first drain well 500 can be drained to the second drain well 700 through the first drain pipe 600. In case the first measured value is greater than the second preset threshold value, the first controller 110 activates the drain pump 130 and closes the cut-off valve 140, the drain pump 130 may forcibly drain the accumulated water in the first reservoir 300 into the second drain well 700, and the accumulated water in the second drain well 700 may be prevented from flowing backward into the first drain well 500 by closing the cut-off valve 140. Therefore, the drainage pump 130 can be started to drain the first water reservoir 300 only when the first measured value is greater than the second preset threshold value, that is, the drainage pump 130 is not started in advance to drain, so that the power consumption of the drainage pump 130 is reduced, and the service life of the drainage pump 130 is prolonged.

In an alternative embodiment, the number of drain pumps 130 is one. Since the number of the drain pumps 130 is small, when the amount of water is large, the drain pumps 130 need to be operated for a long time and with a high load, and the service life of the drain pumps 130 is likely to be short. Therefore, in another alternative embodiment, the drainage pump 130 may include a first drainage pump 131 and a second drainage pump 132, the intelligent drainage system may further include a second controller 150, and the first drainage pump 131 and the second drainage pump 132 are electrically connected to the first controller 110 through the second controller 150; in the case that the first measured value is smaller than the third preset threshold, the first controller 110 starts the first drain pump 131 by controlling the second controller 150; in case the first measurement value is greater than the fourth preset threshold value, the first controller 110 activates the first drain pump 131 and the second drain pump 132 by controlling the second controller 150. In this embodiment, since the number of the drain pumps 130 is large, even if the amount of water in the first water reservoir 300 is large, the drain pumps 130 do not need to operate for a long time and with a high load, which is advantageous to extend the service life of the drain pumps 130. In addition, when the accumulated water amount is small, the first drain pump 131 can be started first, and when the accumulated water amount is large, the second drain pump 132 is started, which is beneficial to improving the efficiency of the first drain pump 131 and the second drain pump 132. When the next drainage is performed, the second drainage pump 132 can be started first, and then the first drainage pump 131 can be started, which is beneficial to prolonging the service life of the drainage pump 130. The third preset threshold may be greater than or equal to the second preset threshold, and the third preset threshold may be less than or equal to the fourth preset threshold. The second controller 150 may be a Programmable Logic Controller (PLC) or another type of controller, which is not limited in this embodiment.

The entire intelligent drainage system may be disabled if the first controller 110 and/or the second controller 150 are not operated, and thus the intelligent drainage system may further include a third controller 160, and the third controller 160 is electrically connected to the first controller 110. In the case that the first controller 110 and/or the second controller 150 cannot operate, the third controller 160 may take over the first controller 110 and/or the second controller 150 to continue operating, so that the continuous operation of the entire intelligent drainage system may be guaranteed. The third controller 160 may be a Programmable Logic Controller (PLC) or another type of controller, which is not limited in this embodiment of the present application.

In order to make it possible to adapt the water discharge amount of the drain pump 130 to the water level variation rate in the first reservoir 300 according to the magnitude of the water flow rate in the overflow pipe 400, the intelligent drainage system may further include a frequency converter 170, and the drain pump 130 is electrically connected to the second controller 150 through the frequency converter 170. In the case that the water level variation rate in the first reservoir 300 is fast, the water discharge amount of the drain pump 130 may be increased by the frequency converter 170, that is, the drain pump 130 operates at a high load; in case that the rate of change of the water level in the first reservoir 300 is slow, the discharge amount of the drain pump 130 may be reduced by the frequency converter 170, i.e., the drain pump 130 operates at a low load, thereby adapting to the rate of change of the water level in the first reservoir 300. Under different drainage conditions, a proper drainage mode is selected, which is beneficial to preventing the drainage pump 130 from being in a high-load operation state all the time, so that the drainage pump 130 can be protected.

The overflow pipe 400 is generally buried under the ground, and therefore, it is impossible to know in time whether the accumulated water in the first drainage well 500 enters the first reservoir 300 from the overflow pipe 400, and if the water flow rate in the overflow pipe 400 is large, the rate of increase of the water level of the accumulated water in the first reservoir 300 is made to be fast, and if the drainage efficiency is not increased, the first reservoir 300 is easily filled. Therefore, the intelligent drainage system may further include a flow meter 180, the flow meter 180 is configured to be disposed on the overflow pipe 400, the flow meter 180 is configured to obtain a second measurement value of the overflow pipe 400, the flow meter 180 is electrically connected to the first controller 110, and the first controller 110 controls the flow rates of the first drainage pump 131 and the second drainage pump 132 through the frequency converter 170 according to the second measurement value. And in case the second measured value is smaller than the fifth preset threshold, the first controller 110 starts the first drain pump 131 by controlling the second controller 150; in case the second measurement value is greater than the sixth preset threshold, the first controller 110 activates the first drain pump 131 and the second drain pump 132 by controlling the second controller 150. When the accumulated water in the first drainage well 500 flows through the overflow pipe 400, the flow meter 180 measures the water flow rate in the overflow pipe 400 to obtain a second measurement value, then the first controller 110 controls the flow rates of the first drainage pump 131 and the second drainage pump 132 according to the second measurement value, and the second controller 150 can selectively start the first drainage pump 131 and the second drainage pump 132 according to the second measurement value and the magnitudes of a fifth preset threshold value and a sixth preset threshold value, so that the increase rate of the accumulated water level in the first reservoir 300 can be reduced, the drainage efficiency is increased, and the first reservoir 300 is prevented from being full.

In order to control the number and frequency of the activated drainage pumps 130 according to the magnitude of the rainfall, the intelligent drainage system may further include a rain gauge 190, the rain gauge 190 is used for obtaining a third measurement value, the rain gauge 190 is electrically connected to the first controller 110, and the first controller 110 controls the flow rates of the first drainage pump 131 and the second drainage pump 132 through the frequency converter 170 according to the third measurement value. In the case that the third measurement value is smaller than the seventh preset threshold value, the first controller 110 starts the first drain pump 131 by controlling the second controller 150; in case the third measurement value is greater than the eighth preset threshold, the first controller 110 activates the first drain pump 131 and the second drain pump 132 by controlling the second controller 150. The rain gauge 190 can measure the amount of rain to obtain a third measured value, and then according to the third measured value, the first controller 110 controls the flow rates of the first drain pump 131 and the second drain pump 132 through the frequency converter 170, and the second controller 150 can selectively start the first drain pump 131 and the second drain pump 132 according to the third measured value and the magnitudes of the seventh preset threshold and the eighth preset threshold, so that the quantity and the frequency of the start of the drain pumps 130 can be controlled according to the amount of rain, which is beneficial to better operation of the intelligent drain system.

Because some devices in the intelligent drainage system work in a relatively harsh environment and are easy to damage, in order to know which device is damaged and the position of the device in time, the intelligent drainage system may further include an equipment damage detection device 200, the equipment damage detection device 200 is electrically connected to the first controller 110, and the equipment damage detection device 200 is used to obtain the first detection value. The first detection value obtained by the device damage detection apparatus 200 can timely know which device is damaged and the position of the device.

In order to intuitively understand the first measurement value, the second measurement value, the third measurement value and the first detection value, the intelligent drainage system may further include a display 210, the display 210 is electrically connected to the first controller 110, and the display 210 may display the first measurement value, the second measurement value, the third measurement value and the first detection value. The first measurement value, the second measurement value, the third measurement value and the first detection value can be visually displayed through the display 210, and the operation condition of the intelligent drainage system can be conveniently and timely known by an operator.

When the water accumulated in the second drainage well 700 is excessive, the reverse flow is likely to occur, that is, the water in the second drainage well 700 is likely to enter the first reservoir 300 through the second drainage pipe 800. To solve this problem, the intelligent drainage system may further include a second water reservoir 220, the second water reservoir 220 being located at a position higher than the first water reservoir 300, the second water reservoir 220 having a protrusion 221 at a bottom thereof. The second drain 800 may include a first tube section 810 and a second tube section 820, the drain pump 130 being in communication with the second reservoir 220 through the first tube section 810, the second reservoir 220 being in communication with the second drain well 700 through the second tube section 820, the protrusion 221 being located between the first tube section 810 and the second tube section 820. In this embodiment, since the second water reservoir 220 is located at a position higher than the first water reservoir 300 and the bottom of the second water reservoir 220 is provided with the protrusion 221, the water accumulated in the second drainage well 700 is not easy to enter the first water reservoir 300, thereby being beneficial to preventing the water accumulated in the second drainage well 700 from flowing backwards.

While the present embodiments have been described with reference to the accompanying drawings, it is to be understood that the invention is not limited to the precise embodiments described above, which are meant to be illustrative and not restrictive, and that various changes may be made therein by those skilled in the art without departing from the spirit and scope of the invention as defined by the appended claims.
