[0041] Please refer to the attached Figures 1-4 , whereFigure 1 Structural schematic diagram of the energy-saving drainage device for power grid civil engineering provided by the present utility model; Figure 2 Front view structural schematic diagram of the support structure in the present utility model; Figure 3 Cross-sectional structural schematic diagram of the support structure in the present utility model; Figure 4 Structural schematic diagram of the drainage module in the present utility model.

[0042] Please refer to the appendix Figures 1-4 , an energy-saving drainage device for power grid civil engineering provided by the present utility model can reduce the huge energy loss in the previous drainage process by setting a number of drainage modules 210 on the support structure 200 and controlling each drainage module 210. The energy-saving drainage device for power grid civil engineering includes:

[0043] The main body 100 of the pumping machine, on which a number of through holes 110 are provided, and a solenoid valve 120 is provided on each through hole 110; The main body 100 of the pumping machine is the core component of the entire energy-saving drainage device. It is responsible for lifting the accumulated water from low-lying or underground areas to the ground or other designated discharge points. The main body 100 of the pumping machine is usually driven by an electric motor. The selection of the electric motor should consider efficiency and energy consumption to achieve the goal of energy conservation and emission reduction. For example, a permanent magnet synchronous motor can be used. This kind of motor has the characteristics of high efficiency, low noise and long life, and is suitable for energy-saving equipment. The design of multiple through holes 110 on the main body 100 of the pumping machine enables the system to flexibly adjust the drainage path according to actual needs. The solenoid valve 120 equipped on each through hole 110 can accurately control the direction and time of the water flow, so as to achieve fixed-point drainage. For example, in power grid civil engineering, it may be necessary to discharge the accumulated water into different recovery ponds or treatment facilities. Through the intelligent control of the solenoid valve 120, it can ensure that the water is transported to the most suitable location, avoiding the waste of resources caused by blind discharge in the traditional drainage system.

[0044] Support structure 200, on which several drainage modules 210 are provided. The first end of the drainage module 210 is provided with several capillary pores 211, and the second end of the drainage module 210 is provided with a drainage port 212. The several capillary pores 211 communicate with the same drainage port 212, and the through port 110 communicates with the drainage port 212. Among them, the support structure 200 serves as the framework of the entire device, not only providing stable support, but also integrating the drainage module 210, enabling it to effectively collect and guide accumulated water. The design of the support structure 200 needs to consider the load-bearing capacity and corrosion resistance to adapt to the complex outdoor environment. For example, high-strength stainless steel materials can be used. This kind of material not only has high strength, but also is corrosion-resistant and is suitable for long-term exposure in humid environments. The drainage module 210 on the support structure 200 is one of the key innovations. The first end of each module is covered with tiny capillary pores 211. These pore diameters are carefully designed to ensure effective water penetration while preventing larger impurities from entering, reducing the workload of subsequent maintenance. The drainage port 212 at the second end is connected to the through port 110 of the pumping machine main body 100, forming a closed circulation system to ensure the directional flow of water;

[0045] Water level detector 500, which is installed on the first end of the drainage module 210 and is used to monitor the accumulated water situation in real time. The selection of the water level detector 500 should consider the accuracy and response speed to ensure the timely start of the drainage program. For example, an ultrasonic water level sensor can be used. This kind of sensor is not affected by water quality, has high measurement accuracy, and reacts quickly, and is very suitable for use in an automated control system. When the water level reaches the preset threshold, the water level detector 500 will send a signal to the controller 300 to trigger the corresponding drainage operation, thus avoiding potential risks caused by excessive accumulated water, such as unstable foundation or equipment damage.

[0046] Controller 300, which is connected to the solenoid valve 120, the water level detector 500, and the pumping machine main body 100 to form a circuit. The controller 300 is the "brain" of the entire system. It receives data from the water level detector 500, analyzes it, and decides whether to open the solenoid valve 120 and which solenoid valve 120 to open. The controller 300 can be an intelligent system based on a microprocessor, with data processing, logical judgment, and communication functions. For example, a PLC programmable logic controller 300 can be used. This kind of controller 300 has high flexibility and reliability, and can automatically control the opening and closing of the solenoid valve 120 according to the preset program to achieve intelligent management. In addition, the controller 300 can also integrate remote monitoring functions, allowing staff to view the system status in real time through mobile phones or computers, and even remotely adjust parameters, improving the operability and safety of the system.

[0047] With the above structure, this energy-saving drainage device solves the problem that "the drainage devices in the prior art cannot drain water at fixed points, resulting in huge energy consumption". Specifically, through the multi-port 110 design of the pumping machine main body 100 and the precise control of the solenoid valve 120, the fixed-point discharge of water is realized, avoiding unnecessary energy waste; the combination of the water level detector 500 and the controller 300 ensures the automatic operation of the system, reduces the need for manual intervention, and further improves energy efficiency. In addition, the design of the drainage module 210 on the support structure 200 not only improves the water collection efficiency but also simplifies the system maintenance work, achieving the goal of energy conservation and emission reduction overall.

[0048] Please continue to refer to Figure 1 、 Figure 2 As shown in, according to an embodiment of the present invention, the support structure 200 further includes: a support frame 220, on which a plurality of embedding holes are provided, and the drainage modules 210 are respectively installed on the support frame 220 through the embedding holes; a support member 230, which passes through the support frame 220 and is fixed on the side wall of the foundation pit; wherein, the first end of the drainage module 210 contacts the side wall of the foundation pit.

[0049] Specifically, the support structure 200 includes a support frame 220 and a support member 230. The support frame 220 is provided with a plurality of embedding holes for installing the drainage modules 210 to ensure that each drainage module 210 can be accurately aligned and firmly connected to the support frame 220. The first end of the drainage module 210 directly contacts the side wall of the foundation pit to achieve effective hydraulic conduction and pressure balance, thereby improving the drainage efficiency. The support member 230 plays a key supporting role. It passes through the support frame 220 and is fixed to the side wall of the foundation pit, not only enhancing the structural stability of the entire device but also ensuring reliability under various complex geological conditions. The support frame 220 can be made of high-strength steel to withstand large lateral pressures and weight loads. The design of the embedding holes needs to consider the size and shape of the drainage modules 210 to ensure a tight fit between the two and avoid poor drainage caused by loosening or misalignment. The support members 230 are usually steel bars or prestressed anchor rods, and their lengths and strengths need to be accurately calculated to ensure that the support frame 220 can be firmly fixed to the side wall of the foundation pit. Considering the influence of soil types and groundwater levels, appropriate materials and construction methods are selected, such as using chemical anchor agents to increase the connection strength or adopting drilling and grouting techniques to reinforce the joint between the support member 230 and the side wall of the foundation pit. In addition, to improve the drainage efficiency, the first end of the drainage module 210 should adopt special materials or structural designs, such as setting a microporous filter layer, which can not only effectively intercept impurities to prevent blockage but also ensure unobstructed water flow, thereby achieving the established energy-saving drainage effect.

[0050] In some embodiments of the present invention, please refer toFigure 1 , Figure 3 , the support structure 200 further includes a drainage board 240. A plurality of channels are provided on the drainage board 240, and the channels penetrate through the first surface 241 and the second surface 242 of the drainage board 240. The arrangement of the channels on the first surface 241 of the drainage board 240 is the same as the arrangement of the drainage module 210 so that each drainage port 212 is detachably connected to the channels on the first surface 241 of the drainage board 240, and the arrangement of the channels on the second surface 242 of the drainage board 240 is the same as the arrangement of the through ports 110.

[0051] Specifically, a plurality of channels are provided on the drainage board 240, and these channels penetrate from one side, the first surface 241, of the drainage board 240 to the other side, the second surface 242. The layout of the channels on the first surface 241 of the drainage board 240 matches the layout of the drainage module 210, ensuring that each drainage port 212 can form a detachable connection with the corresponding channels on the first surface 241 of the drainage board 240, thus realizing flexible installation and maintenance. In addition, the layout of the channels on the second surface 242 of the drainage board 240 is consistent with the layout of the through ports 110. This design ensures that water can flow smoothly from the drainage ports 212 through the channels on the drainage board 240 to the predetermined drainage area, improving the drainage efficiency and reducing water retention, thereby reducing energy consumption and reflecting the energy-saving characteristics of the device.

[0052] Please refer to Figure 1 , in some embodiments of the present invention, the drainage board 240 and the through ports 110 are fixedly communicated through a plurality of telescopic hoses 400.

[0053] Through the above structure, not only the stability and reliability of the drainage system are ensured, but also its ability to adapt to different working environments is improved. Specifically, the telescopic hoses 400 should have good elasticity and corrosion resistance to adapt to various complex working conditions that may be encountered in the grid civil engineering, such as temperature changes, soil pressure, etc., while ensuring the sealing performance and durability under long-term use.

[0054] A further technical implementation method is as follows: between the drainage board 240 and the through ports 110, special telescopic hoses 400 are used for connection. These hoses are usually made of highly elastic materials such as silica gel or PTFE (Teflon) to ensure that they can freely expand and contract under external forces without affecting the stability of the overall structure. In addition, in order to enhance the sealing effect at the connection, O-rings or other types of seals can be provided on the contact surfaces of the telescopic hoses 400 with the drainage board 240 and the through ports 110, and the hoses are firmly fixed in place through fasteners such as clamps or bolts, thereby forming a flexible and reliable drainage channel. This design enables the grid civil engineering energy-saving drainage device to operate effectively under various terrain conditions, while reducing the maintenance cost and failure rate, and improving the energy efficiency and environmental protection performance of the entire system.

[0055] In some embodiments of the present utility model, the main bodies of several telescopic software are bonded into an integral structure, and both ends of several telescopic soft rods are separated from each other.

[0056] Specifically, in order to enhance the overall stability and durability of the device, several telescopic soft rods are designed to be bonded into an integral structure through their main body parts. This bonding method ensures a tight connection between the telescopic soft rods, thereby improving the adaptability and structural strength of the entire device in complex environments. At the same time, in order to maintain the independent movement function and flexibility of the telescopic soft rods, their two ends remain separated from each other. In this way, it not only ensures the compactness and integrity of the device but also does not lose the independent working ability of individual components, achieving the optimization of the structure and the coordination and unity of the functions.

[0057] Please refer to Figure 4 , in some embodiments of the present utility model, a filter screen is provided at the first end of the drainage module 210, and the filter screen completely covers the capillary tube.

[0058] Through the above structure, the filter screen can effectively intercept impurities and particulate matters during the drainage process, thereby protecting the entire drainage system from the risk of blockage, while maintaining the efficient operation of the system and extending its service life. This design not only improves the drainage efficiency but also reduces the maintenance cost, reflecting the energy-saving and environmental protection concept of the device.

[0059] In terms of further technical implementation, select suitable filter screen materials, such as stainless steel or high-strength plastics. These materials not only have good corrosion resistance and strength but also can ensure stable performance under long-term use; secondly, according to the specific size and shape of the capillary tube, customize a matching filter screen structure to ensure that the filter screen can closely fit on the surface of the capillary tube to form a seamless coverage; thirdly, in the design of the filter screen, the aperture size needs to be considered. It should not only be able to effectively filter out larger particles that may cause blockage but also ensure unobstructed water flow. Usually, the aperture size should be optimized and adjusted according to the drainage water quality and the expected filtration effect; finally, during the installation process, it is necessary to ensure that the connection between the filter screen and the capillary tube is firm and reliable to avoid displacement or damage of the filter screen caused by vibration or water flow impact, affecting the filtration effect. Through the above technical means, the design goal of the filter screen completely covering the capillary tube in the power grid civil engineering energy-saving drainage device can be effectively achieved, improving the performance and reliability of the overall device.

[0060] In some embodiments of the present utility model, please refer to Figure 4 , an installation hole 250 is provided at the first end of the drainage module 210, and the water level detector 500 is installed on the installation hole 250, and the water level detector 500 extends out of the filter screen.

[0061] With the above structure, the water level detector 500 can provide an accurate and stable installation position. The water level detector 500 is fixed to the drainage module 210 through the installation hole 250, and its probe part can effectively extend outside the filter screen, thus ensuring real-time monitoring of water level changes and accurate feedback, avoiding the risk of overflow or equipment damage caused by too high water level, and also facilitating the achievement of energy-saving goals.

[0062] In some embodiments of the present invention, please refer to Figure 1 , a water storage tank 600 is connected to the drainage port 212 of the pumping machine main body 100.

[0063] With the above structure, the design of the water storage tank 600 can achieve effective recycling and reuse of water resources, thereby improving the energy efficiency and environmental protection performance of the entire system. Specifically, when the pumping machine main body 100 generates or discharges waste water during operation, this waste water will be directly guided into the water storage tank 600 for storage. The design of the water storage tank 600 can not only collect and temporarily store this waste water, but may also be equipped with a purification or filtration system to ensure that the water quality meets the standards for reuse.

[0064] Further technical implementation methods may include: setting up a pipeline system between the pumping machine main body 100 and the water storage tank 600. This pipeline system should have good sealing performance and sufficient strength to prevent leakage and ensure the smooth transmission of waste water. In addition, to improve the utilization efficiency of the water storage tank 600, a water level sensor can be installed inside the water storage tank 600. By monitoring the water level change, the working state of the pumping machine can be automatically controlled. For example, when the water level reaches the preset upper limit, the pumping machine stops working to avoid overflow; when the water level is lower than the preset lower limit, the pumping machine is started to ensure that there is enough water in the water storage tank 600 for subsequent use. At the same time, the water storage tank 600 can also be configured with a recycling system, such as pumping the preliminarily treated water back to the links that need water through a water pump, such as the cooling system, cleaning equipment, etc., so as to realize the closed-loop recycling of water resources, significantly reduce the demand for fresh water sources, and achieve the purpose of energy conservation and emission reduction. This design not only helps to save precious water resources, but also reduces the impact on the environment.

[0065] In some embodiments of the present invention, please refer to Figure 4 , a shock-absorbing platform 700 is provided at the bottom of the pumping machine main body 100.

[0066] Specifically, it reduces the vibration and noise generated during equipment operation, thereby improving the stability of the system and extending the service life of the equipment. Specifically, the shock-absorbing platform 700 is usually made of high-elastic materials such as rubber or polyurethane. These materials can effectively absorb and disperse the vibration energy generated during the operation of the pumping machine, preventing it from being directly transmitted to the ground or other structures, and thus avoiding equipment damage or performance degradation caused by vibration.

[0067] In some embodiments of the present utility model, please refer to Figure 4 , a shipping hook 800 is provided at the bottom of the shock-absorbing platform 700, and the shipping hook 800 is used to cooperate with large walking equipment for handling.

[0068] Specifically, the shipping hook 800 can be made of high-strength alloy material to ensure sufficient bearing capacity and durability. The shape of the hook should be designed to facilitate quick connection and separation from the lifting device on the large walking equipment. For example, standard eye bolts or quick-release hooks can be used. In addition, to improve safety, the connection part between the hook and the shock-absorbing platform should be fixed by welding or high-strength bolts to ensure that it will not loosen due to vibration or impact during handling. In practical applications, operators need to have a full understanding of the usage method and load-bearing limit of the hook to avoid safety hazards caused by overloading or improper operation. At the same time, it is recommended to clearly mark the maximum load-bearing capacity and correct usage method of the hook in the device instruction manual or on the equipment to guide users to operate correctly and ensure the safety of personnel and equipment during handling.

In this specification, the schematic representations of the above terms do not necessarily refer to the same embodiment or example.
