[0001] The present application relates to the field of drainage technology, and in particular to a drainage system and a drainage system control method. Background Art

[0002] A pumped storage power station (hereinafter referred to as a power station) is a hydropower station that uses electricity during low-load periods to pump water to an upper reservoir and releases water to a lower reservoir for power generation during peak load periods. It is also called a storage hydropower station. Usually, the rainfall at the power station is relatively abundant. In order to prevent rainwater from flowing back, drainage ditches are set up on both sides of the corridors and tunnels in the power station. The numerous drainage ditches in the power station form a drainage system.

[0003] The drainage ditches in the power station include a large number of branch drainage ditches located upstream and a main drainage ditch located downstream. The water in the branch drainage ditches first converges into the main drainage ditch and then is discharged through the main drainage ditch.

[0008] Optionally, each gate unit is provided with two gate bodies, and the two gate bodies are arranged in parallel along the width direction of the branch drainage ditch, and the gate bodies and driving components are connected one by one.

[0009] Optionally, a branch trough opening is provided at the top of the branch trough, and the branch drainage ditch includes a branch cover plate which is detachably covered on the branch trough opening, and the branch cover plate is connected to a battery and an identification light electrically connected to the battery, and the identification light is located on the top of the branch cover plate; the drive assembly is electrically connected to the battery.

[0010] Optionally, a main road trough opening is provided at the top of the main road trough, the main road drainage ditch includes a main road cover plate detachably covering the main road trough opening, the main road flow monitoring component is connected to the bottom of the main road cover plate, and the main road flow monitoring component includes a radar flow velocity sensor.

[0011] Optionally, a solar panel is connected to the top of the branch road cover plate and / or the top of the main road cover plate, and the solar panel is electrically connected to the battery.

[0012] Optionally, each of the branch drainage ditches is connected to a branch flow monitoring component, and the branch flow monitoring component is electrically connected to the controller, and the branch flow monitoring component is configured to obtain and send the branch flow value of the water flow in the corresponding branch drainage ditch.

[0013] Optionally, the drainage system further includes a terminal communicatively connected to the controller, wherein the terminal is configured to display the main flow value, the branch flow value, and to send the gate closing instruction through the controller.

[0014] Based on the same inventive concept, the second aspect of the present application further provides a drainage system control method, using the drainage system as described in the first aspect, the method comprising:

[0039] In order to make the objectives, technical solutions and advantages of the present application more clearly understood, the present application is further described in detail below in combination with specific embodiments and with reference to the accompanying drawings.

[0040] It should be noted that the relative arrangement of the components, the numerical expressions and numerical values ​​set forth in these embodiments do not limit the scope of the present application unless specifically stated otherwise.

[0041] At the same time, it should be understood that for the convenience of description, the sizes of the various parts shown in the drawings are not drawn according to the actual proportional relationship.

[0042] The following description of at least one exemplary embodiment is merely illustrative in nature and is in no way intended to limit the present application, its application, or uses.

[0043] It should be noted that, unless otherwise defined, the technical terms or scientific terms used in the embodiments of the present application should be the usual meanings understood by people with ordinary skills in the field to which the present application belongs. The "first", "second" and similar words used in the embodiments of the present application do not represent any order, quantity or importance, but are only used to distinguish different components. "Including" or "comprising" and similar words mean that the elements or objects appearing in front of the word cover the elements or objects listed after the word and their equivalents, without excluding other elements or objects. "Connect" or "connected" and similar words are not limited to physical or mechanical connections, but can include electrical connections, whether direct or indirect. "Up", "down", "left", "right" and the like are only used to indicate relative positional relationships. When the absolute position of the described object changes, the relative positional relationship may also change accordingly.

[0044] like Figure 1 The drainage system provided in the embodiment of the present application includes a main drainage ditch 100 and a plurality of branch drainage ditches 200. The plurality of branch drainage ditches 200 are arranged upstream of the main drainage ditch 100, and the plurality of branch drainage ditches 200 are respectively connected to the main drainage ditch 100.

[0045] by Figure 1 The structure and direction shown are used as an example for explanation. Three branch drainage ditches 200 are arranged in parallel along the left-right direction. During normal drainage, water in the three branch drainage ditches 200 will converge into the main drainage ditch 100 and be discharged.

[0046] However, at a certain moment (for example, when a sudden rainstorm occurs), when excessive water flows into one of the branch drainage ditches 200, the real-time flow value of the branch drainage ditch 200 may be too large. If other branch drainage ditches 200 still keep draining water into the main drainage ditch 100, the real-time flow value of the main drainage ditch 100 may also exceed the preset safety flow value, and the main drainage ditch 100 may overflow with water.

[0047] If the main drainage ditch 100 overflows, not only the area where the main drainage ditch 100 is located may be flooded, but the branch drainage ditches 200 connected to the main drainage ditch 100 will also fail to drain water normally. Then, the areas where the branch drainage ditches 200 are located may also be flooded, resulting in a large-scale collapse of the drainage system and the power station will suffer great losses.

[0048] The applicant has found that if the real-time flow value of the main drainage ditch 100 exceeds the preset safety flow value, the branch drainage ditch 200 connected to the main drainage ditch 100 can be cut off in time, so that the water inflow of the main drainage ditch 100 can be reduced, and accordingly, the flow value of the main drainage ditch 100 will gradually decrease, so that the main drainage ditch 100 can resume normal drainage. Then the area corresponding to the main drainage ditch 100 and the area where other branch drainage ditches 200 that have not been cut off are located can avoid overflow and waterlogging, at least the scope of waterlogging that may occur in the power station due to excessive drainage pressure can be reduced, and the losses suffered by the power station can be reduced.

[0049] In view of this, if Figure 1 , Figure 2 , Figure 3 and Figure 4 In some embodiments, the drainage system includes: a gate unit 300, connected between the branch drainage ditch 200 and the main drainage ditch 100, and the gate unit 300 corresponds to the branch drainage ditch 200 one by one; the gate unit 300 includes a gate 310 and a drive component 320, the gate 310 has an open state and a closed state that can be switched to each other, and the drive component 320 is at least configured to receive a gate closing instruction and drive the gate 310 to switch from an open state to a closed state according to the gate closing instruction; a main road flow monitoring component 500, arranged in the main road drainage ditch 100, the main road flow monitoring component 500 is configured to obtain and send the main flow value of the water flow in the main road drainage ditch 100 (the main flow value, that is, the flow value of the water flow in the main road drainage ditch 100); a controller, respectively connected to the main road flow monitoring component 500 and the drive component 320 for communication, the controller is configured to receive the main flow value, and in response to the main flow value being higher than the preset flow value, send a gate closing instruction to at least one drive component 320.

[0050] Exemplarily, the controller may be a server or an industrial computer located at a remote location.

[0051] Exemplarily, the gate 310 may be a flat gate that opens and closes by sliding, or a circular gate that opens and closes by rotating.

[0052] Exemplarily, the main flow monitoring component 500 may include a water flow sensor and a water flow rate sensor.

[0053] The main flow monitoring component 500 obtains the current main flow value of the water flow in the main drainage ditch 100 in real time and sends it to the controller. After receiving the current main flow value, the controller will compare it with the pre-stored preset flow value. If the current main flow value is less than the preset flow value, it means that the main drainage ditch 100 is currently draining normally, and the gates 310 corresponding to each branch drainage ditch 200 can all remain in an open state so that each branch drainage ditch 200 can drain water to the main drainage ditch 100; if the current main flow value is greater than the preset flow value, it means that the main drainage ditch 100 is currently overloaded. At this time, the controller can send a gate closing instruction to the drive component 320 in the gate unit 300 corresponding to at least one branch drainage ditch 200, so that the gate 310 in the gate unit 300 is switched to a closed state, so that the branch drainage ditch 200 is disconnected from the main drainage ditch 100, and the water inflow of the main drainage ditch 100 is reduced.

[0054] When the main flow value of the main drainage ditch 100 drops below the preset flow value, the gate 310 in the closed state can be switched back to the open state (for example, the controller can send an opening command to the corresponding drive component 320, and the drive component 320 drives the gate 310 according to the opening command) to allow each branch drainage ditch 200 to resume normal drainage.

[0055] The drainage system provided in this embodiment can monitor the main flow value of the water flow in the main drainage ditch 100 in real time through the main flow monitoring component 500 and the controller. When the main flow value of the main drainage ditch 100 is greater than the preset flow value, the controller can control the drive component 320 of the gate unit 300 corresponding to one of the branch drainage ditches 200 to drive the gate 310 to switch to a closed state, so that the branch drainage ditch 200 is disconnected from the main drainage ditch 100, thereby reducing the water inflow of the main drainage ditch 100, reducing the drainage pressure of the main drainage ditch 100, and reducing the risk of overflow and waterlogging in the areas corresponding to the main drainage ditch 100 and other branch drainage ditches 200, which helps to ensure that most of the drainage system can work normally and that most areas in the power station can maintain normal drainage.

[0056] like Figure 2 , Figure 3 and Figure 4In some embodiments, each branch drainage ditch 200 includes a branch trough body 210 embedded in a base, and the main drainage ditch 100 includes a main trough body 110 embedded in a base, and the main trough body 110 is provided with a water inlet 111 corresponding to the branch trough body 210 one by one; the gate 310 includes a frame 311 and a gate body 312, the frame 311 is fixedly connected to the branch trough body 210 and the corresponding water inlet 111 respectively, and the frame 311 is provided with a drainage opening 314, and the branch drainage ditch 200 can be connected with the main drainage ditch 100 through the drainage opening 314; the gate body 312 is arranged in the drainage opening 314 and is hinged to the frame 311; the driving assembly 320 includes a motor 321 and a transmission assembly 322, and the motor 321 is used to drive the gate body 312 to rotate to block the drainage opening 314 or rotate to open the drainage opening 314 through the transmission assembly 322.

[0057] Exemplarily, the substrate may be the ground.

[0058] Exemplarily, the gate body 312 is a plate-shaped structure.

[0059] Exemplarily, the radial cross-section of the branch trough body 210 and the radial cross-section of the main trough body 110 may both be U-shaped structures.

[0060] Exemplarily, the shape of the frame 311 matches the radial cross-sectional shape of the branch drainage ditch 200 , that is, when the radial cross-sectional shape of the branch drainage ditch 200 is square, the shape of the frame 311 is also square.

[0061] Exemplarily, the shape of the gate body 312 matches the shape of the drainage opening 314 , that is, when the drainage opening 314 is square, the frame 311 and the gate body 312 are also square to ensure that the gate body 312 can better block the drainage opening 314 .

[0062] Exemplarily, the gate body 312 may be fixedly connected to a rotating shaft 313 , and both ends of the rotating shaft 313 extend out of the gate body 312 and are rotatably connected to the frame 311 .

[0063] Exemplarily, the frame 311 may be fixedly connected to the branch tank 210 and the water inlet 111 by welding or fastener connection.

[0064] Exemplarily, the water inlet 111 may be a square tube structure welded to the main channel body 110 .

[0065] Exemplarily, the motor 321 may be a submersible motor or a wireless remote-controlled motor with a certain waterproof function.

[0066] Exemplarily, the transmission assembly 322 may include a gear set, wherein one of the two gears meshing with each other is mounted on the rotating shaft 313, and the other is mounted on the output shaft of the motor 321. Alternatively, the transmission assembly 322 may also include two synchronous pulleys and a synchronous belt, wherein one of the two synchronous pulleys is mounted on the rotating shaft 313, and the other is mounted on the output shaft of the motor 321, and the synchronous belt is simultaneously mounted on the two synchronous pulleys.

[0067] like Figure 3 When the gate 310 is in a closed state, the gate body 312 blocks the drainage opening 314 , the branch drainage ditch 200 corresponding to the gate unit 300 is disconnected from the water inlet 111 , and the branch drainage ditch 200 stops draining water into the main drainage ditch 100 .

[0068] like Figure 3 When the motor 321 receives the gate closing command and opens, it drives the gate body 312 to rotate through the transmission component 322 (the rotation direction is as follows Figure 3 in the direction of the dashed arrow).

[0069] like Figure 4 After the gate body 312 rotates, the drainage opening 314 is no longer blocked, and the branch drainage ditch 200 can drain water into the main drainage ditch 100 through the drainage opening 314, that is, the gate 310 is switched to the open state.

[0070] In this embodiment, the gate body 312 blocks the drainage opening 314 or opens the drainage opening 314 by rotating. Compared with the sliding opening and closing method of the gate body 312, the structure of the gate unit 300 of this embodiment is more compact, which helps to reduce the space occupied by the gate 310 when switching from a closed state to an open state, and facilitates the setting of the gate unit 300 in the base.

[0071] If the gate body 312 is opened and closed by sliding, a slide groove for guiding the gate body 312 needs to be provided on the frame 311, and the slide groove will be partially submerged in water. When the branch drain ditch 200 is draining water, the water flow may be mixed with some debris, and the debris may enter the slide groove with the water flow, thereby hindering the sliding of the gate body 312, causing the gate 310 to be unable to switch to a closed state.

[0072] The gate body 312 of this embodiment is opened and closed by rotation. Since no slide groove is provided on the frame 311, the problem that the gate 310 cannot be switched to the closed state due to debris in the water getting stuck in the frame 311 can be avoided.

[0073] like Figure 3 In some embodiments, each gate unit 300 is provided with two gate bodies 312, and the two gate bodies 312 are arranged along the width direction of the branch drainage ditch 200 (such as Figure 3 The gate bodies 312 and the drive components 320 are arranged in parallel in the X direction, and are connected one by one.

[0074] Exemplarily, when the gate 310 is in a closed state, the two gate bodies 312 are assembled to block the drainage opening 314 .

[0075] Exemplarily, the two gate bodies 312 are symmetrically arranged, that is, the two gate bodies 312 are split structures.

[0076] In this embodiment, the two gate bodies 312 are respectively provided with a driving assembly 320, so that the two gate bodies 312 can be controlled separately. For example, when the real-time main flow value of the main road drainage ditch 100 is greater than the preset flow value, but is relatively close to the preset flow value, a gate closing instruction can be sent to one of the driving assemblies 320 of the gate unit 300, thereby blocking part of the drainage opening 314 to reduce the drainage volume of the branch drainage ditch 200, and also to achieve the purpose of reducing the water inflow of the main road drainage ditch 100. At the same time, the risk of overflow and waterlogging in the area corresponding to the branch drainage ditch 200 due to the complete disconnection of the branch drainage ditch 200 from the main road drainage ditch 100 can also be reduced.

[0077] like Figure 1 , Figure 3 and Figure 4 In some embodiments, a branch trough opening 211 is provided at the top of the branch trough 210, and the branch drain ditch 200 includes a branch cover plate 220 that is detachably covered on the branch trough opening 211, and the branch cover plate 220 is connected to a battery 400 and an identification light 900 that is electrically connected to the battery 400, and the identification light 900 is located at the top of the branch cover plate 220; the drive assembly 320 is electrically connected to the battery 400.

[0078] Exemplarily, the branch cover plate 220 may be provided with a plurality of through holes, and the accumulated water outside the base may flow into the branch trough body 210 through the through holes.

[0079] Exemplarily, the identification lamps 900 disposed on different branch drains 200 may emit light of different colors, and the different branch drains 200 may be distinguished by the light colors of the identification lamps 900 .

[0080] The battery 400 can power the motor 321 and the identification light 900 of the driving assembly 320 to ensure that the motor 321 and the identification light 900 can work normally. When the gate 310 corresponding to a branch drain ditch 200 cannot be switched between the open state and the closed state, the maintenance personnel can quickly find the location of the branch drain ditch 200 in the power station through the identification light 900, which helps to improve the maintenance efficiency of the drainage system.

[0081] like Figure 2 In some embodiments, a main road trough opening 112 is provided at the top of the main road trough 110, the main road drainage ditch 100 includes a main road cover plate 120 that is detachably covered on the main road trough opening 112, and a main road flow monitoring component 500 is connected to the bottom of the main road cover plate 120, and the main road flow monitoring component 500 includes a radar flow velocity sensor.

[0082] In this embodiment, a radar flow velocity sensor is used to obtain the main flow value of the water flow in the main trough 110. The radar flow velocity sensor can be set outside the water flow, which helps to extend the service life of the main flow monitoring component 500, helps to improve the accuracy of the flow value obtained in the main drainage ditch 100, and can adjust the water flow of the main drainage ditch 100 more timely.

[0083] like Figure 2 , Figure 3 and Figure 4 In some embodiments, a solar panel 700 is connected to the top of the branch cover plate 220 and / or the top of the main cover plate 120 , and the solar panel 700 is electrically connected to the battery 400 .

[0084] Exemplarily, the drainage system may further include a power source, which is electrically connected to the battery 400 and can charge the battery 400 when the battery 400 is low on power.

[0085] When there is sufficient sunlight, the battery 400 can be charged by the solar panel 700, which helps to improve the energy-saving effect of the drainage system of this embodiment.

[0086] like Figure 3 and Figure 4 In some embodiments, each branch drainage ditch 200 is connected to a branch flow monitoring component 600, and the branch flow monitoring component 600 is electrically connected to the controller. The branch flow monitoring component 600 is configured to obtain and send the branch flow value (branch flow value, i.e., the flow value of the water flow in the branch drainage ditch 200) of the water flow in the corresponding branch drainage ditch 200.

[0087] Exemplarily, the branch flow monitoring component 600 is the same as the main flow monitoring component 500 .

[0088] Exemplarily, the branch flow monitoring assembly 600 is installed in the same manner as the main flow monitoring assembly 500 .

[0089] The controller can monitor the branch flow values ​​of the water flow in each branch drainage ditch 200 through the branch flow monitoring component 600. When the main flow value corresponding to the main drainage ditch 100 is too large and a certain gate 310 needs to be switched to a closed state, the controller can select the driving component 320 corresponding to which branch drainage ditch 200 to send the gate closing instruction based on the branch flow values ​​corresponding to each branch drainage ditch 200.

[0090] like Figure 5 In some embodiments, the drainage system further includes a terminal 800 communicatively connected to the controller, and the terminal 800 is configured to display a main flow value, a branch flow value, and send a gate closing instruction through the controller.

[0091] Exemplarily, the terminal 800 may be a mobile phone or a tablet computer.

[0092] For example, Figure 5 The terminal 800 may include a touch screen 810. The touch screen 810 may provide a virtual button 811. When a user triggers a virtual button 811 (eg Figure 5 After "Close a" in the figure), the controller can send a closing command to the corresponding drive component 320 (that is, the drive component 320 corresponding to the branch drain ditch a), thereby manually closing the branch drain ditch 200 corresponding to the drive component 320.

[0093] Of course, the user triggers another virtual button 811 (eg Figure 5 After "open a" in the figure), the controller can send an opening command to the corresponding drive component 320 (that is, the drive component 320 corresponding to the branch drainage ditch a), so as to manually connect the branch drainage ditch 200 corresponding to the drive component 320 to the main drainage ditch 100 again.

[0094] Through the terminal 800, the operator can remotely observe the main flow value corresponding to the main drainage ditch 100 of the drainage system and the branch flow value corresponding to the branch drainage ditch 200, so as to understand the water accumulation situation in the area corresponding to each drainage ditch.

[0095] At the same time, the area with less water accumulation and less urgency of drainage can be determined according to the flow values ​​of each branch, and the branch drainage ditch 200 corresponding to the area can be manually closed.

[0096] Based on the same inventive concept and in combination with the description of the drainage system in the above embodiments, this embodiment provides a drainage system control method, which has the corresponding technical effects of the display modules in the above embodiments, and will not be described in detail here.

[0097] like Figure 6This embodiment provides a drainage system control method, using the drainage system as described in the above embodiments, the method includes:

[0098] Step S100, receiving a current main flow value corresponding to the water flow in the main drainage ditch.

[0099] The main flow monitoring component 500 obtains the current main flow value of the water flow in the main drainage ditch 100 in real time and sends the current main flow value to the controller. After receiving the current main flow value, the controller compares the current main flow value with the preset flow value corresponding to the main drainage ditch 100 stored in advance to determine whether the current water flow in the main drainage ditch 100 is normal.

[0100] Step S200, in response to the current main flow value being greater than a preset flow value, at least one gate closing operation is performed with the preset flow value as a target.

[0101] The one-time gate closing operation includes:

[0102] Step S210 , determining the target branch drainage ditch 200 .

[0103] Step S220, sending a gate closing instruction to the driving assembly 320 corresponding to the target branch drainage ditch 200.

[0104] If the comparison result shows that the current main flow value is greater than the corresponding preset flow value, it indicates that the main drainage ditch 100 has been overloaded and there is a risk of overflow. At this time, the controller needs to select one of the multiple branch drainage ditches 200 connected to the main drainage ditch 100 as the target branch drainage ditch, and send a gate closing instruction to the drive component 320 corresponding to the target branch drainage ditch, so that the drive component 320 drives the gate 310 to switch from the open state to the closed state, thereby closing the target branch drainage ditch to reduce the water inflow of the main drainage ditch 100.

[0105] However, after shutting off a branch drain ditch 200, if the main flow value newly received by the controller is still greater than the preset flow value, the controller needs to select another one from the remaining multiple branch drain ditches 200 connected to the main drain ditch 100 as a new target branch drain ditch, and send a closing command to the drive component 320 corresponding to the new target branch drain ditch to shut off the new target branch drain ditch, thereby further reducing the water inflow of the main drain ditch 100.

[0106] After shutting off the two branch drainage ditches 200, if the newly received main flow value is still greater than the preset flow value, the above process is repeated to shut off the third branch drainage ditch 200; if the newly received main flow value is less than the preset flow value, the gate closing operation is no longer performed, so that the drainage system temporarily drains according to the current connection structure of the main drainage ditch 100 and the branch drainage ditch 200.

[0107] Exemplarily, when there is a closed branch drainage ditch 200 and the main flow value newly received by the controller meets the preset conditions (for example, the current main flow value is less than the preset flow value, and the difference between the two is greater than the preset value), the closed branch drainage ditch 200 can be opened one by one to make the branch drainage ditch 200 reconnected with the main drainage ditch 100.

[0108] In some embodiments, step S210 includes:

[0109] Step S211, receiving the current branch flow value of the water flow in each branch drainage ditch.

[0110] A branch flow monitoring component 600 is provided in each branch drainage ditch 200. Each branch flow monitoring component 600 can obtain the current branch flow value of the water flow in the corresponding branch drainage ditch 200 in real time and send the current branch flow value to the controller.

[0111] Step S212, sorting the plurality of current branch flow values ​​from small to large to obtain a branch flow value sequence.

[0112] After receiving the current branch flow values ​​corresponding to the plurality of branch drains 200, the controller sorts all the current branch flow values ​​from small to large. Figure 5 c), it means that the more water accumulates in the area corresponding to the branch drainage ditch 200, the more urgent the drainage demand is, and it is necessary to give priority to ensuring that the branch drainage ditch 200 can drain water normally. On the contrary, the smaller the current branch flow value (such as Figure 5 b) in the figure indicates that the less water accumulation in the area corresponding to the branch drainage ditch 200, the less urgent the drainage demand is, and the branch drainage ditch 200 can be closed first.

[0113] Step S213: determine the first non-zero current branch flow value in the branch flow value sequence as the target branch flow value, and determine the branch drainage ditch 200 corresponding to the target branch flow value as the target branch drainage ditch.

[0114] If the current branch flow value is zero, it means that the corresponding branch drain ditch 200 has been closed.

[0115] In this embodiment, it is necessary to select a target branch drainage ditch from a plurality of branch drainage ditches 200 that are still connected to the main drainage ditch 100 , and therefore, it is necessary to select a non-zero current branch flow value in the branch flow value sequence.

[0116] Combined with the above content, the smaller the current branch flow value is, the less water accumulates in the area corresponding to the branch drainage ditch 200, and the smaller the risk of flooding after the branch drainage ditch 200 is shut off. Therefore, the minimum current branch flow value is preferentially selected as the target branch flow value, and the corresponding branch drainage ditch 200 is shut off, which can effectively reduce the risk of flooding in the local area caused by shutting off the branch drainage ditch 200.
