Description

Technical Field

[0001] This utility model belongs to the technical field of automatic switching units, specifically relating to an automatic switching unit that can drain water. Background Technology

[0002] Power plant unit drainage systems are a crucial aspect of the power industry. Each year, power plant units discharge approximately 160,000 tons of wastewater. Occasionally, some of this wastewater is used for unit cleaning, and its quality is poor, requiring wastewater treatment. However, in most cases, the discharged water is of good quality with low conductivity, meeting the criteria for recycling. Traditional drainage designs typically discharge this water directly into the sewage network, but this practice leads to significant water waste and increases the economic burden on enterprises.

[0003] Traditional drainage systems fail to adequately consider the recycling and reuse of wastewater with relatively good water quality, leading to a waste of usable water resources. Businesses not only incur costs for wastewater and sewage treatment but also waste significant amounts of potentially recyclable water, increasing operating costs. To address this, a new wastewater treatment solution is urgently needed that can both treat unit cleaning water and efficiently recycle and reuse wastewater with relatively good water quality. Utility Model Content

[0004] This invention proposes an automatic switching unit capable of drainage. It features two water pumps housed within a casing, along with horizontal and vertical drainage pipes. An automatic switching mechanism allows for the switching between drainage and water recycling based on changes in water quality. The system automatically identifies water quality and sends water meeting recycling standards into the recycling pipes, avoiding unnecessary wastewater discharge, thus reducing water waste and lowering wastewater treatment costs. This addresses the issues of water waste and economic burden in existing technologies.

[0005] The technical solution of this utility model is as follows: an automatic switching unit capable of draining water includes: an equipment box, a ground, an input pipe, a horizontal output pipe and a vertical output pipe. The top of the equipment box is provided with a sealing cover. The equipment box is buried under the ground. A first water pump is fixedly connected to the inner wall of the equipment box. The end of the input pipe is connected to the input end of the first water pump. The input end of the horizontal output pipe is set at the output end of the first water pump.

[0006] A connecting pipe is provided on one side of the input pipe, and the connecting pipe is connected to the input pipe. A second water pump is fixedly connected to the inner wall of the equipment box. The end of the connecting pipe is located at the input end of the second water pump. The output end of the second water pump is connected to the vertical output pipe, and the vertical output pipe passes through the sealing cover and the ground.

[0007] Preferably, a first solenoid valve is provided inside the input pipe. The first solenoid valve is located between the connecting pipe and the input end of the input pipe.

The second solenoid valve is located on one side of the output end of the first water pump and realizes the regulation of the flow rate of the transverse pipe by electromagnetic control. The structure of the second solenoid valve is a combination of valve body and electromagnet.

[0008] Preferably, a vertical solenoid valve is installed inside the connecting pipe. The vertical solenoid valve is located on the side near the input end of the second water pump. The vertical solenoid valve has a combination structure of valve core and spring, and adjusts the flow rate of the vertical output pipe by electromagnetic drive. A sealing valve is installed inside the vertical output pipe. The sealing valve is located on the output end side of the second water pump, and the sealing valve has a rubber sealing structure.

[0009] Preferably, the equipment box is equipped with a power supply, which is a DC power supply. The equipment box is also equipped with a main unit, which consists of an integrated circuit board and a processor.

[0023] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this utility model.

[0024] Please see Figure 1-4 An automatic switching unit capable of drainage includes: an equipment box 1, a ground 2, an input pipe 4, a horizontal output pipe 8 and a vertical output pipe 12. The top of the equipment box is provided with a sealing cover 17. The equipment box is buried below the ground 2. A first water pump 7 is fixedly connected to the inner wall of the equipment box. The end of the input pipe 4 is connected to the input end of the first water pump 7. The input end of the horizontal output pipe 8 is located at the output end of the first water pump 7.

[0025] A connecting pipe 10 is provided on one side of the input pipe 4, and the connecting pipe 10 is connected to the input pipe 4. A second water pump 13 is fixedly connected to the inner wall of the equipment box 1. The end of the connecting pipe 10 is located at the input end of the second water pump 13. The output end of the second water pump 13 is connected to the vertical output pipe 12. The vertical output pipe 12 passes through the sealing cover 17 and the ground 2.

[0026] The unit is designed with two water pumps, 7 and 13, which can automatically switch as needed through the cooperation of the inlet pipe 4 and the connecting pipe 10. This ensures that if one water pump 7 or 13 fails or requires maintenance, the other water pump 7 or 13 can take over, ensuring the continuous and stable operation of the equipment and avoiding the inconvenience caused by downtime. Since the equipment box 1 is buried underground at ground level 2, the compact design effectively saves ground space. This underground installation method also reduces the impact of the external environment on the equipment, such as weather and debris interference.

[0027] The first pump 7 supplies water to the horizontal output pipe 8, while the second pump 13 supplies water to the vertical output pipe 12. This rational division of labor improves drainage efficiency and system operational flexibility. The complementary roles of the two pumps 7 and 13 can share pressure under high loads, avoiding overuse of a single pump. A sealing cover 17 is installed at the top of the equipment box 1 to effectively prevent water or debris from entering the equipment box 1, protecting the internal equipment. The sealing cover 17 and the embedded structure enhance the equipment's waterproofness, ensuring its stability during long-term use.

[0028] During system operation, the vertical output pipe 12 passes through the sealing cover 17 and the ground 2, increasing the reliability of the equipment. During drainage, the direction and flow rate of the water can be well controlled, avoiding problems such as leakage or uneven system pressure. The unit is designed for various drainage environments, especially suitable for locations requiring efficient drainage, such as underground projects and drainage systems. By adjusting the switching between pumps 7 and 13, the flow rate can be automatically adjusted according to drainage needs. The equipment box 1 is buried underground and has a compact structure, facilitating regular inspection and maintenance. Especially when pumps 7 and 13 fail, the design of the two pump systems makes replacement and maintenance more convenient.

[0029] The input pipe 4 is equipped with a first solenoid valve 6, which is located between the connecting pipe 10 and the input end of the input pipe 4. The first solenoid valve 6 automatically controls the flow of fluid in the input pipe 4 by means of electromagnetic drive. The transverse output pipe 8 is equipped with a second solenoid valve 9, which is located on one side of the output end of the first water pump 7. The second solenoid valve 9 is controlled by electromagnetic control to regulate the flow of the transverse pipe. The structure of the second solenoid valve 9 is a combination of valve body and electromagnet.

[0030] Both the first solenoid valve 6 and the second solenoid valve 9 are electromagnetically driven, enabling automated control. This automation not only reduces manual intervention but also improves the operating efficiency and precision of the equipment. Through the automatic control of solenoid valves 6 and 9, the system can automatically adjust the flow rate or on / off state of the fluid as needed to adapt to different drainage requirements.

[0031] The second solenoid valve 9, located in the transverse output pipe 8, can precisely control the water flow rate. Through electromagnetic control, the output flow rate of the water pump 7 can be finely adjusted, ensuring the system's drainage efficiency and flow stability, avoiding excessive or insufficient water flow, and improving the system's operational stability. The precise control of solenoid valves 6 and 9 can adjust the water flow according to actual needs, avoiding unnecessary load on the water pump 7 and energy waste. When a large flow rate is not required, the second solenoid valve 9 can automatically adjust the flow rate, reducing energy consumption and improving energy utilization.

[0032] The connecting pipe 10 is equipped with a vertical solenoid valve 11, which is located near the input end of the second water pump 13. The vertical solenoid valve 11 is a combination structure of valve core and spring, and adjusts the flow rate of the vertical output pipe 12 by electromagnetic drive. The vertical output pipe 12 is equipped with a sealing valve 14, which is located on the output end side of the second water pump 13. The sealing valve 14 is a rubber sealing structure.

[0033] The vertical solenoid valve 11 is electromagnetically driven, enabling precise control of the flow rate in the vertical output pipe 12. Due to its combined valve core and spring structure, the valve can quickly respond to system demands, ensuring high precision in flow regulation, optimizing the working efficiency of the water pump 13, and reducing flow fluctuations.

[0034] The sealing valve 14 uses a rubber sealing structure, which effectively prevents liquid leakage and ensures the sealing performance of the pipeline system. The rubber sealing structure has excellent wear resistance and corrosion resistance, and can maintain a good sealing effect during long-term operation, reducing maintenance needs and failure risks, and enhancing system reliability.

[0035] The system achieves automated flow regulation and control through the electromagnetic drive of the vertical solenoid valve 11. This avoids errors and delays caused by manual operation, ensuring that the system can flexibly adjust the flow according to real-time needs under various operating conditions, thereby improving the overall system efficiency and response speed.

[0036] The equipment box 1 is equipped with a power supply 16, which is a DC power supply. The equipment box 1 is also equipped with a main unit 18, which consists of an integrated circuit board and a processor. The outer wall of the vertical output pipe 12 is equipped with a level gauge 15, which is an ultrasonic sensor that can monitor the drainage volume and liquid level in real time. The level gauge 15 transmits the monitoring data to the main unit 18 through a wireless module.

[0037] The level gauge 15 monitors the drainage volume and liquid level in real time using an ultrasonic sensor, enabling it to accurately and promptly capture changes in water level. This real-time monitoring effectively prevents situations where the liquid level is too high or too low, ensuring the normal operation of the equipment. Simultaneously, the monitoring data is transmitted wirelessly to the main unit 18, avoiding complex wiring and simplifying system installation and maintenance.

[0038] The main unit 18 consists of an integrated circuit board and a processor, enabling it to process, analyze, and transmit data. Through analysis of liquid level data, the main unit 18 can intelligently adjust system operation, automatically control the switching on and off of water pumps 7 and 13, and optimize drainage efficiency. This intelligent control not only improves the automation level of the equipment but also effectively avoids human error. Power is supplied by a DC power supply 16, which is highly efficient and stable. The DC power supply 16 is more suitable than AC power for the long-term stable operation of electronic equipment and can effectively reduce energy loss. In terms of energy saving, the DC power supply 16 typically consumes less electrical energy, improving the system's energy utilization efficiency and reducing operating costs.

[0039] The input end of the input pipe 4 is equipped with a filter screen 5, which is a stainless steel woven mesh structure. The output end of the vertical output pipe 12 is equipped with a dust cover 19, which is a detachable structure with a spring device. During drainage, the dust cover 19 automatically opens and automatically closes after drainage is completed. The outer wall of the ground is equipped with a solar panel 20, which is a monocrystalline silicon photovoltaic panel. The solar panel 20 integrates a battery and an inverter. The battery is a lithium battery, and the inverter is a DC-AC converter.

[0040] The filter screen 5 of the inlet pipe 4 uses a stainless steel woven mesh structure, which can effectively filter impurities, particles, and contaminants in the water and prevent them from entering the system. This not only protects internal components such as water pumps 7 and 13 and pipes from damage, but also improves the long-term stability and reliability of the equipment.

[0041] The dust cover 19 features a spring mechanism and a detachable structure, allowing it to automatically open during drainage and close automatically after drainage is complete. This design eliminates the hassle of manual operation, increases the system's automation level, reduces intervention during maintenance and use, and enhances operational convenience and system adaptability.

[0042] Solar panel 20 uses monocrystalline silicon photovoltaic panels, combined with a battery and inverter system, to efficiently collect and store solar energy. Through lithium battery energy storage and a DC-AC converter, solar power not only provides power support for the system but also reduces dependence on traditional electricity, achieving energy conservation and emission reduction, increasing the energy self-sufficiency of the equipment, and improving its environmental friendliness and economic efficiency.

[0043] The outer wall of the equipment box 1 is provided with a side support plate 3, which is made of steel and concrete composite. The structure of the side support plate 3 is a combination of L-shaped angle steel and concrete pouring structure. The equipment box 1, the side support plate 3 and the sealing cover 17 are all made of poured concrete. The outer wall of the equipment box 1 is made of reinforced concrete material and the inner wall is a smooth concrete coating.

[0044] The side support plate 3 is constructed of a composite of steel and concrete, using L-shaped angle steel combined with a concrete pouring structure. This composite material structure significantly enhances the compressive strength and stability of the equipment box 1. Concrete provides high compressive strength, while steel enhances the structure's toughness and durability, ensuring long-term stable operation of the equipment in various harsh environments.

[0045] Equipment box 1, side support plate 3, and sealing cover 17 are all made of cast concrete, and the outer wall of equipment box 1 is made of reinforced concrete. This gives the entire equipment better protection against external impact, corrosion, and harsh weather conditions. Reinforced concrete has significant advantages in weather resistance, seismic resistance, and corrosion resistance, effectively extending the service life of the equipment.

[0046] The inner wall of equipment enclosure 1 is coated with a smooth concrete layer. This design reduces the accumulation of dirt and deposits, facilitating cleaning and maintenance. Furthermore, the smooth surface helps reduce material adhesion, preventing system inefficiency or malfunctions due to dirt buildup, thus improving equipment operating efficiency and ease of maintenance.

[0047] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
