Description

Technical Field

[0001] The present invention relates to the technical field of pumping stations, and particularly to a pumping station for water conservancy projects and a drainage control method. Background Art

[0002] A pumping station is a key facility for lifting and conveying water bodies to achieve functions such as irrigation, drainage, water supply, flood control, and water resource allocation. The power is converted into the potential energy or kinetic energy of the water body through a water pump group, playing an important role in the water conservancy system.

[0003] Existing pumping stations for water conservancy projects generally include a base, a housing, and a water pump. The base is fixedly installed at a designated position. The housing is fixedly installed on the base through flanges and bolts. The water pump is installed inside the housing and placed on the base. The water inlet and outlet of the water pump are respectively connected with a water inlet pipe and a water outlet pipe, and are communicated with the outside through the water inlet pipe and the water outlet pipe, so as to pump water from a low water level to a high water level through one or more groups of water pumps to achieve the scheduling of water sources.

[0004] During the operation of the pumping station for water conservancy projects, the water pump needs to achieve the lifting and long-distance conveying of the water body through pressure, resulting in a large pressure at the water outlet pipe, and it is extremely easy to have a leakage phenomenon. In the existing pumping stations for water conservancy projects, the water pump is installed on the base and is located inside the housing. The base and the housing do not have the ability to prevent water accumulation. The leaked water will accumulate inside the housing and flood the water pump, which is troublesome to clean up later, and the accumulation of water is likely to cause damage to the water pump; in addition, the bases of existing pumping stations for water conservancy projects are mostly constructed by on-site binding and grouting. The installation process of the pumping station is complex and the installation firmness is poor. Summary of the Invention

[0005] In order to solve the technical problem in the above background art that the existing pumping stations for water conservancy projects do not have the ability to prevent water accumulation, the leaked water will accumulate inside the housing and flood the water pump, which is troublesome to clean up later, and the accumulation of water is likely to cause damage to the water pump, the present invention provides a pumping station for water conservancy projects.

[0006] The technical solution of the present invention is as follows: The present invention provides a water conservancy project pumping station, which includes a base and a housing fixedly installed on the base. A water pump is provided inside the housing, and the water pump is connected with a water inlet pipe and a water outlet pipe. A first partition board and a control center are fixedly installed inside the housing. The control center is located above the first partition board. A plurality of water leakage holes are formed on the first partition board. The water pump is fixedly installed on the first partition board, and a liquid level sensor is installed on the first partition board. A drain pipe is installed at the bottom of the housing, and the drain pipe is located between the first partition board and the base. An electromagnetic valve is installed on the drain pipe. The liquid level sensor, the electromagnetic valve, and the water pump are all electrically connected to the control center. By using the first partition board to raise the position of the water pump, when the water outlet pipe leaks during operation, the leaked water flows through the water leakage holes to the lower part of the first partition board. After the water level height in the lower part of the first partition board reaches the preset height, the liquid level sensor transmits the actual water level height signal to the control center. After receiving the signal, the control center controls the electromagnetic valve to work, and then opens the drain pipe to drain the leaked water in the lower part of the first partition board out of the housing, avoiding flooding the water pump. At the same time, the control center controls the water pump to stop pumping, avoiding damage to the water pump caused by soaking, and improving the overall anti-waterlogging ability of the pumping station.

[0007] Preferably, the water leakage holes are in a horn-shaped structure with a larger upper part and a smaller lower part. The horn-shaped water leakage holes can expand the water inlet area at the top, accelerate the drainage speed of the leaked water to the lower part of the first partition board, reduce the retention time of the water above the first partition board, and reduce the risk of the accumulated water overflowing the bottom of the water pump. At the same time, the smaller aperture at the lower part can block larger impurities from entering the bottom area to a certain extent, avoid clogging of the drain pipe, and ensure the smoothness of the drainage system.

[0008] Preferably, the water pump is located on the side of the water leakage holes close to the water inlet pipe, which can make the leaked water around the water pump flow more directly through the nearby water leakage holes to the lower part of the first partition board, shorten the water flow path, and improve the drainage efficiency. At the same time, it can avoid the water pump base covering the water leakage holes, ensure the effectiveness of the accumulated water drainage, and further improve the anti-waterlogging ability of the pumping station.

[0009] Preferably, a second partition board is fixedly provided inside the housing. The second partition board is located above the first partition board. The control center is fixedly installed on the second partition board. The water outlet pipe is located below the second partition board. By setting the second partition board to separate the control center and the water outlet pipe in different areas, it can avoid the water directly contacting the electrical components of the control center when the water outlet pipe leaks, reduce the risk of circuit short circuit, and ensure the stability and safety of the control system. At the same time, the hierarchical layout makes the internal space function of the housing more clearly divided, facilitating quick positioning of the fault area during later maintenance and improving the maintenance efficiency.

[0010] Preferably, a ladder is fixedly arranged between the second partition plate and the first partition plate. The upper end of the ladder passes through the second partition plate, and the lower end of the ladder is close to the first partition plate. The provision of the ladder provides a passage for the staff from the area of the second partition plate to the first partition plate area, facilitating the staff to move down to the first partition plate to repair, maintain or clean the accumulated water residues of equipment such as water pumps and drain pipes. The setting that the upper end of the ladder passes through the second partition plate ensures the stability of the ladder installation. The setting that the lower end of the ladder is close to the first partition plate reduces the occupation of the installation space of the equipment above the first partition plate and improves the utilization rate of the internal space of the housing.

[0011] Preferably, a lighting lamp and a human body sensor are fixedly installed at the bottom of the second partition plate. Both the human body sensor and the lighting lamp are electrically connected to the control center. The human body sensor can detect the activities of the personnel inside the housing in real time. When it detects that someone moves below the second partition plate, the control center can automatically control the electrical components after receiving the signal. The setting of the lighting lamp can illuminate the space between the second partition plate and the first partition plate, facilitating the carrying out of the maintenance work.

[0012] Preferably, an air inlet is opened at the upper end of the housing, and a blower is fixedly installed at the air inlet. The blower is electrically connected to the control center. The blower is connected with an air supply pipe, and the lower end of the air supply pipe passes through the second partition plate and extends downward to the upper part of the first partition plate. The blower conveys fresh air to the area above the first partition plate through the air supply pipe, which can accelerate the air circulation inside the housing. When the staff enters the bottom of the housing for maintenance work, the blower can be used to convey fresh air into the housing to ensure sufficient oxygen in the housing and improve the comfort and safety of the maintenance work.

[0013] Preferably, a flow sensor is installed on the water outlet pipe. The flow sensor is electrically connected to the control center, which can monitor the water flow rate data of the water outlet pipe in real time and transmit the data to the control center. When the flow rate data shows abnormal fluctuations (such as sudden decrease or sharp increase), the control center can give an early warning in time and automatically control the work of devices such as water pumps and solenoid valves, improving the overall anti-waterlogging ability of the pumping station.

[0014] Preferably, support columns are fixedly installed at the bottom of the base. The support columns are of a hollow structure. The support columns are fixedly connected with grouting pipes, and slurry outlets are arranged at the bottom ends of the support columns. During the installation process of the pumping station, high-pressure mortar pumps can be used to pump concrete mortar along the grouting pipes into the vertically arranged support columns. The pressurized mortar gushes out along the slurry outlets, splitting the surrounding soil layer. After the concrete solidifies, a tree-shaped concrete base is formed, increasing the overall stability of the pumping station and reducing the probability of its inclination. The overall installation process of the pumping station is convenient and fast.

[0015] The present invention provides a drainage control method, including: during the pumping process of water in a low water level, when the outlet pipe leaks, the leaked water flows along the leakage holes to the bottom of the housing. The liquid level sensor monitors the liquid level below the first partition and transmits the liquid level information to the control center. When the liquid level reaches a preset threshold, the control center controls the solenoid valve to open, and the leaked water body is discharged outwards from the drain pipe. At the same time, the control center controls the water pump to stop pumping, so as to discharge the leaked water below the first partition out of the housing, avoiding flooding the water pump. At the same time, the control center controls the water pump to stop pumping, avoiding damage to the water pump caused by immersion, and improving the overall anti-waterlogging ability of the pumping station.

[0016] It can be seen from the above technical solutions that the advantages of the present invention are as follows: 1. The position of the water pump is raised by using the first partition. Thus, when the outlet pipe leaks during operation, the leaked water body flows through the leakage holes to below the first partition. After the water level height below the first partition reaches the preset height, the liquid level sensor transmits the actual water level height signal to the control center. After receiving the signal, the control center controls the solenoid valve to work, and then opens the drain pipe to discharge the leaked water below the first partition out of the housing, avoiding flooding the water pump. At the same time, the control center controls the water pump to stop pumping, avoiding damage to the water pump caused by immersion, and improving the overall anti-waterlogging ability of the pumping station.

[0017] 2. The leakage holes provided on the first partition are in a trumpet-shaped structure with a larger top and a smaller bottom. The leakage holes in the trumpet-shaped structure can expand the top water inlet area, accelerate the drainage speed of the leaked water body to below the first partition, reduce the retention time of the water body above the first partition, and reduce the risk of waterlogging overflowing the bottom of the water pump; at the same time, the smaller lower aperture can block larger impurities from entering the bottom area to a certain extent, avoid clogging of the drain pipe, and ensure the smoothness of the drainage system.

[0018] 3. A second partition is fixedly provided inside the housing. The second partition is located above the first partition. The control center is fixedly installed on the second partition. The outlet pipe is located below the second partition. By setting the second partition to separate the control center and the outlet pipe in different areas, it can avoid direct contact between the water body and the electrical components of the control center when the outlet pipe leaks, reduce the risk of circuit short circuit, and ensure the stability and safety of the control system; at the same time, the layered layout makes the internal space function of the housing more clearly divided, facilitating quick positioning of the fault area during later maintenance and improving the maintenance efficiency.

[0019] 4. Fix and install support columns at the bottom of the base, and fixedly connect the support columns to the grouting pipes. There is a slurry outlet at the bottom end of the support columns. During the installation process of the pump station, high-pressure mortar pumps can be used to pump the concrete mortar along the grouting pipes into the vertically arranged support columns. The pressurized mortar gushes out along the slurry outlet, splitting the surrounding soil layer. After the concrete solidifies, a tree-branch-shaped concrete base is formed, increasing the overall stability of the pump station and reducing the probability of its inclination. The overall installation process of the pump station is convenient and fast. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] In order to make the objectives, features, and advantages of the present invention more obvious and understandable, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings in the specific embodiments. Obviously, the embodiments described below are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of this patent, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the scope of protection of this patent.

[0023] Embodiment 1 In a typical implementation manner of the present invention, as Figure 1 shown, a water conservancy project pumping station is proposed, including: a housing 1, a first partition 2, a liquid level sensor 3, a solenoid valve 5, a drain pipe 6, a water pump 8, a control center 23, and a base 30. The housing 1 is fixedly installed on the base 30 to support and seal the bottom of the housing 1 through the base 30. The first partition 2 is horizontally and fixedly installed in the housing 1, and the first partition 2 is located directly above the base 30. There is a space between the first partition 2 and the base 30 for accommodating the leaked water body. As Figure 2 shown, a number of water leakage holes 4 are provided on the first partition 2 for the water body to pass through the first partition 2. The water pump 8 is fixedly installed on the first partition 2, and the water inlet and outlet of the water pump 8 are respectively connected to the water inlet pipe 9 and the water outlet pipe 7. The bottom of the side wall of the housing 1 is fixedly installed with a drain pipe 6. The drain pipe 6 is close to the base 30 and is horizontally arranged between the first partition 2 and the base 30. The drain pipe 6 is communicated with the space between the first partition 2 and the base 30 to discharge the accumulated leaked water body below the first partition 2 out of the housing 1 to avoid flooding the water pump 8. The solenoid valve 5 is installed on the drain pipe 6 to control the on-off of the drain pipe 6. The liquid level sensor 3 is fixedly installed on the first partition 2, and the bottom end of the liquid level sensor 3 penetrates through the first partition 2 and extends below the first partition 2 to online monitor the water level height of the accumulated water body below the first partition 2. The control center 23 is fixedly installed in the housing 1 and is located above the first partition 2. The control center 23 is electrically connected to the water pump 8, the liquid level sensor 3, and the solenoid valve 5 respectively.

[0024] The first partition 2 raises the position of the water pump 8. Thus, when the water outlet pipe 7 leaks during operation, the leaked water body flows through the water leakage holes 4 to the lower part of the first partition 2. After the water level height below the first partition 2 reaches the preset height, the liquid level sensor 3 transmits the actual water level height signal to the control center 23. After receiving the signal, the control center 23 controls the solenoid valve 5 to work, and then opens the drain pipe 6 to discharge the leaked water below the first partition 2 out of the housing 1 to avoid flooding the water pump 8. At the same time, the control center 23 controls the water pump 8 to stop pumping.

[0025] At the top end of the housing 1, an audible and visual alarm 22 is also fixedly installed. The audible and visual alarm 22 is electrically connected to the control center 23 through a cable. When it is detected that water leakage occurs in the outlet pipe 7, the control center 23 not only controls drainage and stops the operation of the water pump 8, but also controls the audible and visual alarm 22 to give an alarm to remind the staff to check in time.

[0026] It can be understood that in other embodiments, the control center 23 can also be connected to a remote control center. Thus, when working conditions such as water leakage in the outlet pipe 7 and shutdown of the water pump 8 occur in the hydraulic engineering pumping station, not only can an alarm be given through the audible and visual alarm 22, but also the alarm signal can be transmitted to the remote control center to prompt the staff, improving the alarm ability and effect.

[0027] In this embodiment, a flange is fixedly installed at the bottom of the housing 1, and a flange is also fixedly installed on the base 30. The housing 1 is fixedly installed on the base 30 through bolts to seal and support the bottom of the housing 1 by using the base 30; the first partition 2 is horizontally and fixedly installed inside the housing 1 by welding. A number of water leakage holes 4 are evenly opened at the middle position of the first partition 2. The water leakage holes 4 penetrate through the first partition 2. The water leakage holes 4 are in a flared structure with a larger top and a smaller bottom. The flared water leakage holes 4 can expand the top water inlet area, accelerate the drainage speed of the leaked water to the lower part of the first partition 2, reduce the retention time of water above the first partition 2, and reduce the risk of accumulated water overflowing the bottom of the water pump 8; at the same time, the smaller lower aperture can block larger impurities from entering the bottom area to a certain extent, avoid blockage of the drain pipe 6, and ensure the smoothness of the drainage system. The water pump 8 is fixedly installed on the first partition 2, and the water pump 8 is located on the side of the water leakage holes 4 close to the inlet pipe 9, which can make the leaked water around the water pump 8 flow more directly through the nearby water leakage holes 4 to the lower part of the first partition 2, shorten the water flow path, and improve the drainage efficiency; at the same time, it can avoid the base of the water pump 8 blocking the water leakage holes 4, ensure the effectiveness of accumulated water drainage, and further enhance the anti-accumulation ability of the pumping station. Thus, when water leakage occurs in the outlet pipe 7, the water can flow to the water leakage holes 4 and be directly discharged to the lower part of the first partition 2, which is convenient for protecting the water pump 8.

[0028] A drain port is opened at the bottom of the side wall of the housing 1, and a drain pipe 6 is fixedly installed at the drain port to drain the water in the housing 1 to the outside; an inlet and an outlet are also opened on the side wall of the housing 1. Among them, the inlet on the housing 1 is lower than the outlet. The water pump 8 is connected to the inlet of the housing 1 through an inlet pipe 9, and the water pump 8 is connected to the inlet of the housing 1 through an outlet pipe 7, so that the water at a lower place can be pumped to a higher place by using the water pump 8.

[0029] Such as Figure 1As shown in the figure, a second partition 19 is fixedly provided inside the housing 1. The second partition 19 is horizontally arranged and is located above the first partition 2. The control center 23 is fixedly installed on the second partition 19. In this embodiment, the control center 23 is a control cabinet, which functions as a control center and provides power support for each device. The water outlet end 25 of the water outlet pipe 7 is located below the second partition 19. By setting the second partition 19, the control center 23 and the water outlet pipe 7 are separated in different areas, so as to prevent the leaked water from flowing above the second partition 19. When the water outlet pipe 7 leaks, the water body can be prevented from directly contacting the electrical components of the control center 23, reducing the risk of circuit short - circuit and ensuring the stability and safety of the control system. At the same time, the hierarchical layout makes the functional division of the internal space of the housing 1 clearer, facilitating the rapid positioning of the fault area during later maintenance, improving the maintenance efficiency, and preventing the immersion damage of the control center 23; such as Figure 3 As shown in the figure, an external - clamping type flow sensor 10 is installed on the water outlet pipe 7. The flow sensor 10 is electrically connected to the control center 23 through a sensor wiring 11. It can be used to on - line monitor the water flow pumped in the water outlet pipe 7 by the flow sensor 10, and can assist in judging whether the water outlet pipe 7 leaks according to the change of the flow rate, improving the overall anti - water - accumulation ability of the pumping station.

[0030] There is an installation space between the upper part of the second partition 19 and the top of the housing 1. The control center 23 is located in the installation space between the second partition 19 and the top of the housing 1. A ladder 21 is fixedly provided between the second partition 19 and the first partition 2. The setting of the ladder 21 provides a passage for the staff from the area of the second partition 19 to the area of the first partition 2, facilitating the staff to move down to the first partition 2 to repair, maintain or clean the accumulated water residues of equipment such as the water pump 8 and the drain pipe 6. The upper end of the ladder 21 passes through the second partition 19 and extends into the installation space above the second partition 19, ensuring the stability of the installation of the ladder 21. The lower end of the ladder 21 is located above the first partition 2 and close to the first partition 2. The staff can move from the second partition 19 to the first partition 2 through the ladder 21, reducing the occupation of the equipment installation space above the first partition 2 and improving the utilization rate of the internal space of the housing 1 to meet the maintenance work at different positions.

[0031] Such as Figure 4 As shown in the figure, a passage slot 20 is opened on the second partition 19. The passage slot 20 penetrates the second partition 19. The ladder 21 passes through the second partition 19 downward from the passage slot 20. The passage slot 20 is not only used for the installation of the ladder 21 but also for the passage of the staff, so that the staff can pass through the second partition 19. A lighting lamp 24 is fixedly installed at the bottom of the second partition 19. The lighting lamp 24 is electrically connected to the control center 23. The staff can control the switch of the lighting lamp 24 through the control center 23 to use the lighting lamp 24 to illuminate the space between the second partition 19 and the first partition 2, facilitating the carrying out of the maintenance work.

[0032] In this embodiment, both the first partition plate 2 and the second partition plate 19 are circular plate-like structures to adapt to the cross-sectional shape of the housing 1. Both the first partition plate 2 and the second partition plate 19 are made of metal, and both the first partition plate 2 and the second partition plate 19 are fixedly connected to the inner wall of the housing 1 by welding.

[0033] It can be understood that in other embodiments, the first partition plate 2 and the second partition plate 19 can also be other shapes. The specific shapes of the first partition plate 2 and the second partition plate 19 can be determined according to the actual cross-sectional shape of the housing 1, and no excessive restrictions are imposed here.

[0034] An inspection door opening is provided on the upper side wall of the housing 1, and a safety door 12 is hinged at the inspection door opening. The inspection door opening is located above the second partition plate 19. Workers can enter the interior of the housing 1 through the inspection door opening and stand on the second partition plate 19. A ventilation component is also installed inside the housing 1. Thus, when workers enter the tower body 1, especially when they enter the bottom of the housing 1 for maintenance work, the ventilation component can be used to deliver fresh air into the housing 1 to ensure sufficient oxygen in the housing 1 and improve the comfort and safety of the maintenance work.

[0035] Locking devices are also installed on the safety door 12 and the housing 1 to lock the safety door 12 and the housing 1 through the locking devices, preventing non-workers from freely entering and leaving the housing 1 and ensuring the use safety of the pumping station. It can be understood that the locking devices are existing structures, and the specific structural forms are not elaborated here.

[0036] As Figure 1 shown, the ventilation component includes a fan bracket 13, a blower 15, and an air supply pipe 16. An air inlet 14 is provided on the upper side wall of the housing 1. The fan bracket 13 is fixedly installed inside the housing 1 by welding or other means. The blower 15 is fixedly installed on the fan bracket 13. The air supply pipe 16 is vertically fixedly installed inside the housing 1, and the lower end of the air supply pipe 16 passes through the second partition plate 19 and extends downward to above the first partition plate 2. The blower 15 is respectively connected to the air inlet 14 and the air supply pipe 16. The blower 15 can blow the air outside the housing 1 into the air supply pipe 16 and deliver it to the space between the first partition plate 2 and the second partition plate 19 to ensure the oxygen content in the housing 1. The blower 15 is electrically connected to the control center 23, and the operation of the blower 15 can be controlled through the control center 23.

[0037] As Figure 4As shown in the figure, a pipe slot 17 is formed in the second partition plate 19. The pipe slot 17 penetrates through the second partition plate 19, and the air supply pipe 16 passes downward through the second partition plate 19 through the pipe slot 17. A human body sensor 18 is fixedly installed at the bottom of the second partition plate 19. The human body sensor 18 is electrically connected to the control center 23, and the human body sensor 18 is close to the ladder 21 for monitoring the staff. When the human body sensor 18 detects that a staff member moves down to the space below the second partition plate 19, it can transmit the monitoring signal to the control center 23. The control center 23 can automatically control the operation of the blower 15. The blower 15 starts, inhales external air through the air inlet 14, and conveys it to the space below the second partition plate 19 through the air supply pipe 16, so as to keep the air in the space fresh, prevent the staff from lacking oxygen, improve the automation degree of the control work of the blower 15, avoid omission of ventilation work, and improve the safety of maintenance work.

[0038] Specifically, during maintenance, the staff first enters the housing 1 through the safety door 12 and stands on the second partition plate 19. The staff can control the lighting lamp 24 to turn on through the control center 23, and then move to the lower part of the second partition plate 19 through the ladder 21 and the access slot 20. When the human body sensor 18 senses that there is a staff member below the second partition plate 19, the control center 23 automatically controls the blower 15 to start. The blower 15 inhales fresh air outside the housing 1 through the air inlet 14 and pumps it into the space below the second partition plate 19 through the air supply pipe 16, so as to keep the air in the space below the second partition plate 19 fresh and prevent the staff from lacking oxygen. After the staff moves to the lower part of the second partition plate 19, they can maintain the water pump 8, the water outlet pipe 7, and the drain pipe 6. After the maintenance is completed, the staff can move back to the upper part of the second partition plate 19 through the ladder 21 and the access slot 20, and finally move to the outside of the housing 1 through the safety door 12 to complete the maintenance work.

[0039] As Figure 5 shown, a support column 26 is fixedly installed at the center of the bottom of the base 30 to improve the overall stability of the pumping station by using the support column 26. Specifically, the support column 26 is a hollow structure. The support column 26 is vertically fixedly installed at the center of the bottom of the base 30. The bottom end of the support column 26 is a pointed structure to facilitate the insertion of the support column 26 into the soil layer. The upper end of the support column 26 is fixedly connected with a grouting pipe 29. The inside of the grouting pipe 29 is communicated with the inside of the support column 26. A plurality of slurry outlets 28 are formed on the side wall of the lower end of the support column 26. As Figure 6As shown, before the housing 1 of the buried pumping station is installed, a pile hole is dug on the foundation of the foundation pit. The support column 26 at the bottom of the pumping station is inserted into the pile hole. The concrete mortar is pumped along the grouting pipe 29 into the vertically arranged support column 26 through a high-pressure mortar pump. The pressurized mortar gushes out along the slurry outlet 28, splitting the surrounding soil layer. After the concrete solidifies, a tree-branch-shaped concrete base is formed, increasing the overall stability of the pumping station and reducing the probability of its inclination. The overall installation process of the pumping station is convenient and fast. In this embodiment, in order to prevent the reverse flow of the slurry during the grouting process, a one-way valve 27 is fixedly installed in the support column 26, and the one-way valve 27 is close to the slurry outlet 28.

[0040] In other embodiments, in order to improve the service life of the outlet pipe 7, the water pump 8, and the inlet pipe 9, a filtering component can also be installed between the inlet pipe 9 and the water pump 8. The filtering component can be a single-layer filter screen structure or a multi-layer filter screen structure. Specifically, the filtering component includes a box body and at least one layer of filter screen. The box body is provided with a water inlet and a water outlet. The filter screen is located between the water inlet and the water outlet. The water inlet of the box body is connected to the inlet pipe 9, and the water outlet of the box body is connected to the water pump 8. Thus, the water body pumped into the inlet pipe 9 enters the water pump 9 after being filtered by the filter screen, so as to filter the impurities in the water body by the filter screen and avoid damage to the water pump 8 caused by impurities.

[0041] It can be understood that the filtering component can also be of other structures, and the specific structural form of the filtering component can be determined according to actual design requirements. Specifically, no excessive restrictions are imposed here.

[0042] Embodiment 2 In another typical implementation manner of the present invention, a drainage control method is proposed. The hydraulic engineering pumping station mentioned in Embodiment 1 is adopted. Before the housing 1 of the buried pumping station is installed, a pile hole is dug on the foundation of the foundation pit. The support column 26 at the bottom of the pumping station is inserted into the pile hole. The concrete mortar is pumped along the grouting pipe 29 into the vertically arranged support column 26 through a high-pressure mortar pump. The pressurized mortar gushes out along the slurry outlet 28, splitting the surrounding soil layer. After the concrete solidifies, a tree-branch-shaped concrete base is formed, increasing the overall stability of the pumping station and reducing the probability of its inclination.

[0043] The drainage control method using the above-mentioned hydraulic engineering pumping station specifically includes: The water source at a low water level is pumped into the inlet pipe 9. The water body pumped into the inlet pipe 9 is lifted to a high position along the outlet pipe 7 and the water outlet end 25 under the pumping of the water pump 8, and finally is conveyed to a designated position through a pipeline. During the pumping process of water bodies at low water levels, the water pump 8 needs to lift and transport water bodies over long distances through pressure, resulting in a relatively large pressure at the outlet pipe 7. When the outlet pipe 7 leaks, the first partition 2 raises the position of the water pump 8, and the leaked water flows along the water leakage holes 4 on the first partition 2 to the bottom of the housing 1, rather than accumulating around the water pump 8. The water body flows to the bottom of the first partition 2 for accumulation. The liquid level sensor 3 monitors the liquid level below the first partition 2 and transmits the liquid level information to the control center 23. When the liquid level reaches the preset threshold, the control center 23 controls the solenoid valve 5 to open, and the leaked water body is discharged outward from the drain pipe 6. At the same time, the control center 23 controls the water pump 8 to stop pumping, and the sound and light alarm 22 emits an alarm to remind the staff to check in time; During the process of the water pump 8 pumping water flow along the outlet pipe 7 outward, the flow sensor 10 on the outlet pipe 7 can also be used to assist in monitoring the leakage problem of the outlet pipe 7. Specifically, the flow sensor 10 is used to continuously monitor the internal flow of the outlet pipe 7. When the flow is abnormal, the flow sensor 10 transmits the flow abnormality signal to the control center 23. The control center 23 controls the sound and light alarm 22 to emit an alarm to remind the staff to check in time. At the same time, the control center 23 controls the solenoid valve 5 to open and the water pump 8 to stop pumping. During maintenance, the staff first opens the safety door 12 to enter the housing 1 through the safety door 12 and stand on the second partition 19. The staff controls the lighting lamp 24 to turn on through the control center 23, and then moves to the lower part of the second partition 19 through the ladder 21. When the human body sensor 18 senses that there is a staff member below the second partition 19, the control center 23 automatically controls the blower 15 to start, inhales external air through the air inlet 14, and pumps it into the space below the second partition 19 through the air supply pipe 16 to keep the air fresh in the space below the second partition 19 to prevent the staff from lacking oxygen; after the staff moves to the lower part of the second partition 19, they repair the outlet pipe 7 and the water pump 8. After the repair is completed, the staff moves back to the upper part of the second partition 19 through the ladder 21 and closes the solenoid valve 5 through the control center 23, and restarts the water pump 8 to work; at the same time, when the staff moves to the upper part of the second partition 19, the control center 23 controls the blower 15 to stop working. After the maintenance work is completed, the staff walks out of the housing 1 and locks the safety door 12 to prevent non-staff members from entering the housing 1 of the pumping station.

[0044] In this embodiment, the water pump 8 is lifted by using the first partition 2, and the water leakage holes 4 are provided on the first partition 2. The space below the first partition 2 is used for collecting the leaked water body, and the liquid level sensor 3 is used to monitor the water level below the first partition 2 online. When the water level height reaches the monitoring threshold, it is discharged outward through the drain pipe 6, effectively avoiding the accumulation of the leaked water body around the water pump 8 and preventing the water pump 8 from being flooded, thereby avoiding the immersion damage of the water pump 8.

[0045] The foregoing description of the disclosed embodiments enables those skilled in the art to practice or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Thus, the present invention is not intended to be limited to the embodiments shown herein but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
