Detailed Description
Embodiments of the technical scheme of the present application will be described in detail below with reference to the accompanying drawings. The following examples are only for more clearly illustrating the technical aspects of the present application, and thus are merely examples, and are not intended to limit the scope of the present application.
FIG. 1 schematically shows a plan view of a displacement pump station according to an embodiment of the application; fig. 2 is a cross-sectional view taken along line A-A of fig. 1. As shown in fig. 1 and 2, the drainage pumping station 100 mainly comprises a water inlet channel 1, an emergency gate 2, a direct current gate 12, a temporary storage tank 5, a conveying device 9 and a drainage channel 7. Wherein, the water inlet channel 1 is connected with the temporary storage pool 5 through the emergency gate 2 and is connected with the water outlet channel 7 through the direct current gate 12. Specifically, the water inlet channel 1 has two outlets and one inlet connected to a surface water collecting structure (such as a sump), wherein one outlet is connected to the temporary storage tank 5 through the emergency gate 2, and the other outlet is connected to the water discharge channel 7 through the direct current gate 12. The conveying device 9 is arranged in the temporary storage pool and can convey the water body in the temporary storage pool 5 into the drainage channel 7. The drainage channel 7 comprises a first branch 71, a second branch 72 and a main road 73 connected to the first and second branches 71, 72, wherein the first branch 71 is connected to the water inlet channel 1 via the dc gate 12, the second branch 72 is in communication with the conveying means 9, and the main road 73 is capable of receiving the bodies of water in the first and second branches 71, 72 and discharging them into a receiving body of water, such as a river or lake.
The operation of the drainage pumping station 100 according to the embodiment of the present application will be described. When the emergency gate 2 is closed and the direct current gate 12 is opened, the direct current gate 12 allows the water body in the water inlet channel 1 to sequentially enter the first branch 71, the main road 73 and the receiving water body under the action of potential energy (realized by virtue of hydraulic gradient); when the direct-current gate 12 is closed and the emergency gate 2 is opened, the emergency gate 2 allows the water in the water inlet channel 1 to enter the temporary storage tank 5 under the action of potential energy, so that the conveying device 9 can sequentially convey the water in the temporary storage tank 5 into the second branch 72, the trunk 73 and the receiving water. That is, the drainage pumping station 100 according to the embodiment of the present application can select whether to drain into the receiving water body in a continuous energy consumption manner through the opening and closing conditions of the emergency gate 2 and the direct current gate 12 and the conveying device 9, so that the drainage pumping station 100 can drain the received water body into the receiving water body in a continuous energy consumption manner by means of the conveying device 9 and can drain the received water body into the receiving water body in an energy saving manner by means of potential energy, and therefore the drainage pumping station 100 according to the embodiment of the present application is a novel drainage pumping station having various drainage manners and saving energy consumption.
In this embodiment, the drainage pumping station 100 may further include a backflow prevention flooding valve 13 disposed in the first branch 71 and capable of incompletely sealing the first branch 71. The backflow-preventing type flood valve 13 is configured to block only the lower half of the inner cavity of the first branch 71 and allow water to flow therethrough from the upper half of the inner cavity to create a flood phenomenon from the top of the backflow-preventing type flood valve 13. The advantage of the backflow prevention flooding valve 13 is that: when the receiving water body is at a high tide level and has a backflow phenomenon, if the backflow phenomenon is not serious, the backflow-preventing type overflow valve 13 in a closed state can not only effectively prevent the backflow phenomenon from endangering the safety of the drainage pump station 100 and the city, but also ensure that the received water body accumulates potential energy in the water inlet channel 1 under the action of the potential energy so as to enter the receiving water body after passing through the direct current gate 12, the top of the backflow-preventing type overflow valve 13 and the drainage channel 7.
The drainage pump station 100 operates on the following principle after comprising the backflow prevention overflow valve 13: when the emergency gate 2 is closed and the direct-current gate 12 and the backflow-preventing type flood valve 13 are opened, the direct-current gate 12 and the backflow-preventing type flood valve 13 allow water in the water inlet channel 1 to sequentially enter the first branch 71, the main road 73 and the receiving water body under the action of potential energy; when the direct-current gate 12 is closed and the emergency gate 2 is opened, the emergency gate 2 allows the water in the water inlet channel 1 to enter the temporary storage tank 5 under the action of potential energy no matter whether the backflow-preventing overflow valve 13 is opened or closed, so that the conveying device 9 can sequentially convey the water in the temporary storage tank 5 into the second branch 72, the main 73 and the receiving water; when the emergency gate 2 and the backflow-preventing type overflow valve 13 are closed and the direct-current gate 12 is opened, the direct-current gate 12 allows the water in the water inlet channel 1 to enter the first branch 71 under the action of potential energy, then to overflow from the top of the backflow-preventing type overflow valve 13, and then to enter the trunk 73 and the receiving water body in sequence.
In this embodiment, in order to avoid that impurities in the water body interfere with the operation of the conveying device 9, the drainage pump station 100 further includes a cleaning device 4 disposed in the temporary storage tank 5, and the cleaning device 4 is closer to the emergency gate 2 than the conveying device 9, so that the water body in the temporary storage tank 5 is filtered to remove impurities before entering the conveying device 9. For the cleaning device 4, the skilled person will choose the cleaning degree and the cleaning degree to match the cleaning device according to the specific requirements, for example, in order to avoid the interference of suspended matters and particles in the water flow to the conveying device 9, the cleaning device 4 is preferably a grid type cleaning machine. Wherein, the installation angle of the grid type trash remover is preferably 70 degrees, so as to ensure that the trash removal effect of the grid type trash remover can reach or approach to the best.
In this embodiment, the drainage pumping station 100 further comprises a signal transmission module 16 and a control module 17 connected to the signal transmission module 16. The control module 17 can control the working states of the emergency gate 2, the direct-current gate 12, the backflow-preventing overflow valve 13 and the conveying device 9 based on the signals received by the signal transmission module 16. The signal transmission module 16 may be selected from a remote communication module (Wi-Fi module or 4G network module, etc.) and/or a short-range communication module (bluetooth module or infrared module, etc.) to facilitate the control of the drainage pump station 100, for example, the city rainfall monitoring center or city central control center may actively send a control signal to the remote communication module according to the water level of the receiving water body, weather, etc., so that the control module may selectively control the emergency gate 2, the direct current gate 12, the backflow preventing flooding valve 13 and the conveying device 9 according to the control signal, for example, open the emergency gate 2 and the conveying device 9, and close the direct current gate 12 at the same time, so that the drainage pump station 100 can forcibly and rapidly drain the received water body into the receiving water body at a high tide level. The emergency gate 2, the direct-current gate 12 and the backflow-preventing overflow valve 13 are all preferably electric and manual integrated gates. The control module 17 mainly includes a programmable logic controller (such as a PLC or a CPU), a memory, and electronic components connected to the programmable logic controller, etc., which are well known to those skilled in the art, and will not be described in detail herein.
In this embodiment, the drainage pumping station 100 further comprises a first level gauge 61 provided in the temporary storage tank 5 and/or a second level gauge 62 provided in the first branch 71 downstream of the backflow prevention flooding valve 13. The first liquid level meter 61 is connected to the control module 17 and is used for detecting the water level in the temporary storage tank 5, so that the control module 17 can control the working states of the emergency gate 2 and the conveying device 9 based on the detection signal output by the first liquid level meter 61. For example, when the control module 17 knows that the water level in the temporary storage tank 5 is about to exceed the maximum volume value through the detection signal of the first liquid level meter 61, the control module can actively close the emergency gate 2 and improve the conveying efficiency of the conveying device 9 so as to promote the water level in the temporary storage tank 5 to drop and prevent unnecessary danger; when the control module 17 knows from the detection signal of the first level gauge 61 that the water level in the temporary storage tank 5 is zero, it can shut down the conveyor 9 to prevent it from running continuously under empty conditions. The second level gauge 62 is connected to the control module 17 and is configured to detect the water level in the first branch 71, so that the control module 17 can control the operating states of the emergency gate 2, the direct current gate 12, the backflow preventing flooding valve 13 and the conveying device 9 based on the detection signal output by the second level gauge 62. For example, when the control module 17 knows that the water in the first branch 71 may reversely pass through the backflow preventing overflow valve 13 in the closed state through the detection signal of the second liquid level meter 62, the control module 17 closes the direct current gate 12 and opens the emergency gate 2 and the conveying device 9; when the control module 17 knows that the first branch 71 does not have the backflow phenomenon through the detection signal of the second liquid level meter 62, the emergency gate 2 and the conveying device 9 are closed, and the direct-current gate 12 and the backflow-preventing overflow valve 13 are opened; when the control module 17 knows that the first branch 71 has a slight backflow phenomenon but the water body from the receiving water body cannot reversely pass through the backflow preventing overflow valve 13 in the closed state through the detection signal of the second liquid level meter 62, the control module 17 closes the emergency gate 2 and the conveying device 9, and opens the direct current gate 12 and the backflow preventing overflow valve 13.
In this embodiment, the drainage pumping station 100 further comprises a partition wall 82 extending from the ground towards the bottom of the temporary storage pool 5 and formed with a vertical well 81. And the conveyor 9 comprises an axial flow pump (including a motor) provided in the bottom of the vertical shaft 81. The number of vertical shafts 81 is selected according to actual needs, for example, four vertical shafts 81 and four axial flow pumps. The drainage pump station 100 further comprises a well cover 83 which is arranged on top of the partition wall 82 and can seal the top of the vertical well channel 81, and a wall penetrating channel 84 which penetrates through the tank wall of the temporary storage tank 5 and communicates the vertical well channel 81 with the second branch 72. According to the embodiment, the axial flow pump is installed by adopting the well type structure, so that the axial flow pump can be hidden underground on one hand, and the anti-theft performance of the axial flow pump is improved; on the other hand, the operation such as quick assembly, maintenance and replacement can be performed on the downhole axial flow pump by means of the switching characteristics of the well cover 83. It will be readily appreciated that the delivery device 9 may alternatively be a pump unit, such as a combination of a submersible pump and a tube, with both ends of the tube being connected to the submersible pump and the discharge channel, respectively, in addition to the present embodiment.
When the water body enters the temporary storage pool 5, axial component speed and tangential component speed exist, vortex is generated due to asymmetric distribution of the axial component speed and the tangential component speed, the vortex not only changes the rotating speed of an impeller in the axial flow pump and causes abrasion of a bearing in the pump and overload of a motor, but also causes noise, vibration and bearing load of the axial flow pump 6 when serious, and the water flow state of a pump inlet is changed to generate cavitation, so that the overall performance of the pump is drastically reduced. Therefore, in this embodiment, to improve the adverse factors, one side of the partition wall 82 is connected to the wall of the temporary storage tank 5 far away from the emergency gate 2, and the other side of the partition wall 82 is provided with the first diversion structure 3, so that the first diversion structure 3 can greatly reduce the swirl effect of the conveying device 9 caused by working to promote the water in the temporary storage tank 5. The first flow guiding structure 3 may be an approximate trapezoid, wherein the top surface of the approximate trapezoid is an arc slope 31 gradually increasing towards the direction of the partition wall 82, and the bottom surface of the approximate trapezoid is a flow guiding slope 32 gradually decreasing towards the direction of the partition wall 82.
In this embodiment, the drainage pump station 100 further includes a diversion slope 9 disposed in the temporary storage pool 5. The diversion ramp 9 comprises a diversion plane 91 adjacent to the emergency gate 2 and above the bottom of the scratch pool 5, and a diversion ramp 92 engaging the diversion plane 91 and the bottom of the scratch pool 5. The diversion plane 91 is used for carrying the decontamination device 4, and since the diversion plane 91 is higher than the bottom of the temporary storage tank 5, the diversion plane 91 is used for carrying the decontamination device 4, so that the overall height of the decontamination device 4 is easy to be reduced, and the temporary storage tank 5 is allowed to have a deeper size. Meanwhile, the slope bottom 92a of the diversion slope 92, which is jointed with the bottom of the temporary storage pool 5, is closer to the conveying device 9 than the slope top 92b of the diversion slope, which is jointed with the diversion plane 91, so that the diversion slope 92 can promote water flow to enter the lower part of the conveying device 9 quickly, and can guide water to pass through the trash cleaning device 4 quickly, thereby improving the trash cleaning efficiency of the trash cleaning device 4.
In this embodiment, the drainage pump station 100 may further include a backflow prevention valve 15 disposed in the second branch 72, where the backflow prevention valve 15 can effectively prevent the water in the receiving water body from flowing backward into the temporary storage tank 5 when closed. The anti-backflow valve 15 is preferably an electric or manual integrated gate, and is preferably connected to the control module 17 so as to be controlled together with other valves by the control module 17. The pump station 100 may further include a check valve 11 disposed at the outlet of the through-wall passage 84, the check valve 11 being capable of allowing the axial flow pump to drain water in the temporary storage tank 5 through the through-wall passage 84 to the second branch 72 and also being effective to prevent water in the receiving water from flowing back into the temporary storage tank 5 in the event of an emergency and forgetting to close the anti-backflow valve 15. Among them, the check valve 11 may be preferably a flap valve.
The operation of the pump station 100 under various operating conditions is described in detail below:
in sunny days, the receiving water body presents a low tide level, the direct current gate 12 and the backflow preventing type overflow valve 13 are opened, the emergency gate 2 and the conveying device 9 are closed, and the water body received by the water inlet channel 1 sequentially passes through the first branch 71 and the trunk 73 under the action of potential energy and then enters the receiving water body.
When the receiving water body is in a high tide level in a sunny day, the control module 17 judges whether the water body in the first branch 71 possibly reversely passes through the backflow-preventing overflow valve 13 in a closed state through the detection signal of the second liquid level meter 62, if so, the direct-current gate 12 and the backflow-preventing overflow valve 13 are closed, the emergency gate 2, the conveying device 9 and the backflow-preventing valve 15 are opened, the water body in the water inlet channel 1 enters the temporary storage tank 5 under the action of potential energy, and the opened conveying device 9 can sequentially convey the water body in the temporary storage tank 5 into the second branch 72, the main road 73 and the receiving water body; if not, the direct current gate 12 is opened, the backflow-preventing type overflow valve 13, the emergency gate 2, the conveying device 9 and the backflow-preventing valve 15 are closed, the water body received by the water inlet channel 1 firstly enters the first branch 71 under the action of potential energy, then overflows from the top of the backflow-preventing type overflow valve 13, and then sequentially enters the trunk 73 and the receiving water body.
When the receiving water body is at a low tide level in a rainy day, the direct-current gate 12 and the backflow-preventing overflow valve 13 are opened, the emergency gate 2 and the conveying device 9 are closed, and the water body received by the water inlet channel 1 sequentially passes through the first branch 71 and the trunk 73 under the action of potential energy and then enters the receiving water body.
When the receiving water body is in a rainy day and is at a high tide level, the control module 17 needs to judge whether the water body in the first branch 71 possibly reversely passes through the backflow-preventing overflow valve 13 in a closed state through the detection signal of the second liquid level meter 62, if so, the direct-current gate 12 and the backflow-preventing overflow valve 13 are closed, the emergency gate 2, the conveying device 9 and the backflow-preventing valve 15 are opened, the water body in the water inlet channel 1 enters the temporary storage tank 5 under the action of potential energy, and the opened conveying device 9 can sequentially convey the water body in the temporary storage tank 5 into the second branch 72, the trunk 73 and the receiving water body; if not, the direct current gate 12 is opened, the backflow-preventing type overflow valve 13, the emergency gate 2, the conveying device 9 and the backflow-preventing valve 15 are closed, the water body received by the water inlet channel 1 firstly enters the first branch 71 under the action of potential energy, then overflows from the top of the backflow-preventing type overflow valve 13, and then sequentially enters the trunk 73 and the receiving water body.
The drainage pump station 100 of the embodiment of the application effectively realizes the functions of drainage and drainage of flood, and ensures the life and property safety of people, in particular:
firstly, under the working condition that 90% of the working conditions can be known by combining a typical rainfall process curve of a line model of a rainfall process of a test place (Chicago) with a tide calculation formula and by statistical analysis, water flow can be directly discharged into a receiving water body, the drainage pump station 100 can effectively utilize local terrain, and the drainage pump station can preferentially execute direct current drainage without pump intervention and has the characteristics of being unique as a traditional pump station.
Compared with the traditional drainage pump station, the pump lift ratio of the axial flow pump is smaller, the axial flow pump of the traditional drainage pump station 100 calculates the pump lift to be the pump lift of the water pump for the high water level of the receiving water body or the difference between the flood prevention tide level and the lowest water level designed by the temporary storage pool 5 plus the head loss of the pipeline system. The drainage pumping stations 100 thus configured are each chosen to be the most disadvantageous, as well as the most disadvantageous, in operation. No matter the tide level of the receiving water body, the water pump needs to be frequently started when raining each time, a large amount of electric energy is consumed, the potential energy water head of the water flow cannot be fully utilized, and energy waste is caused.
Thirdly, as described above, the probability of the least favorable strong drainage of the drainage pump station 100 is 10%, and compared with the traditional pump station, the drainage pump station can meet the condition of flood occurrence in 20 years and meet the requirements of national waterlogging prevention and control design standards. Facilities arranged for preventing waterlogging in cities can be omitted, storm which possibly occurs and exceeds the channel design reproduction period can be handled, city safe operation is guaranteed, and the problem of accumulated water drainage in urban areas can be effectively solved.
Fourth, the opening and closing of each gate and the opening and closing of the axial flow pump of the drainage pump station 100 are controlled by a control module, and remote monitoring can be realized without manual duty.
Fifth, the axial flow pump of the drainage pump station 100 can be made of anti-corrosion materials, and can be suitable for various corrosive water bodies, especially for coastal cities.
Sixth, the drainage pump station 100 can avoid investment waste caused by oversized design and safety accidents caused by undersized design in the rain drainage design process.
Seventh, the cooperation of the direct current gate 12 and the backflow-preventing type overflow valve 13 can prevent backflow of the receiving water body on one hand, and can utilize the potential water head of the water head in the channel to discharge the water body on the other hand, and additional energy is not required to be consumed. When the water level of the receiving water body is higher than the water level in the channel, the traditional thinking has to lift the rainwater to the receiving water body by means of lifting equipment, but the application reversely thinks that the water level is accumulated in the channel through the switching of the gate, and potential energy water heads are accumulated, so that the safety in the service area of the pump station is ensured, and the rainwater can be discharged.
