Technical Field

[0001] This utility model relates to the field of water storage tank technology, specifically a secondary water supply water storage tank that ensures continuous water supply. Background Technology

[0002] In recent years, with the rapid development of high-speed rail and the rapid progress of railway construction, the scale of newly built stations has become larger and larger, the passenger flow has increased year by year, and the water consumption has increased accordingly. The requirements for water quality, quantity and pressure have become higher and higher. In order to ensure the emergency water supply capacity in case of municipal water supply failure, newly built stations mostly adopt secondary water supply, equipped with dedicated water storage tanks and booster pumps to meet the daily water use and emergency water supply of the station.

[0003] Currently, the inner walls of existing railway secondary water supply reservoirs are prone to scale and algae deposits, which promote the growth of microorganisms and cause the sanitary indicators of the water inside to exceed the normal range, affecting normal water use. To solve the above problems, it is necessary to rely on manual regular entry into the water tank for washing and cleaning. However, the disinfection devices fixed in the water tank often interfere with the cleaning operations of the staff, which not only reduces the cleaning efficiency but also fails to guarantee the cleaning quality inside the water tank. Summary of the Invention

[0004] The purpose of this utility model is to provide a secondary water supply storage tank that ensures continuous water supply. A foldable sterilization and disinfection mechanism is installed inside the storage tank to avoid interfering with the cleaning operations of the staff and to solve the problems in the prior art.

[0005] The technical solution adopted by this utility model to solve its technical problem is as follows: a secondary water supply storage tank to ensure continuous water supply, comprising a storage tank body located above ground, a pump room installed on one side of the storage tank body, a water pump installed in the pump room, the water pump inlet being connected to the interior of the storage tank body through a pumping pipe, a municipal water supply pipe connected to the interior of the storage tank body also being installed in the pump room, an inspection port and a vent pipe installed on the upper part of the storage tank body, a cover installed on the top of the vent pipe, a drain hole that can be opened and closed on one side of the bottom of the storage tank body, and a foldable sterilization and disinfection device installed on the top of the inner cavity of the storage tank body. The sterilization and disinfection mechanism includes a disc mounted on the top wall of a water storage tank. Several first connecting rods arranged circumferentially are hinged to the disc. A second connecting rod is hinged to the end of each first connecting rod furthest from the disc. Each first connecting rod has a hanging ring, and the top wall of the water storage tank has hooks corresponding to the hanging rings. An ultraviolet germicidal lamp is mounted on the second connecting rod. The first connecting rods are horizontally arranged, and the second connecting rods are vertically arranged. After the hooks are separated from the hanging rings, the second connecting rods can rotate to approach and connect to the first connecting rods. The first and second connecting rods are located at the bottom of the disc and are in a converged and stored state. A quartz glass cylinder is fixedly mounted on the second connecting rod, and the ultraviolet germicidal lamp is located inside the quartz glass cylinder. A detachable top cover is threaded onto the upper end of the quartz glass cylinder, and a sealing ring is installed between the top cover and the quartz glass cylinder. A through hole for a power cord to enter is also provided on the top cover, and a sealing plug that mates with the power cord is installed in the through hole. The length of the first connecting rod is greater than the length of the second connecting rod. A plug is installed at the end of the second connecting rod, and a corresponding insertion hole is provided on the first connecting rod to cooperate with the plug. When the second connecting rod rotates closer to the first connecting rod, the plug can enter the insertion hole to connect the second connecting rod with the first connecting rod. Corresponding to the position of the vent pipe, a vertically movable monitoring cylinder is installed inside the water storage tank. The monitoring cylinder cooperates with the cavity inside the vent pipe. One monitoring cylinder is equipped with a pH detection probe, an ORP detection probe, and a turbidity detection probe, and the other monitoring cylinder is equipped with an electronic level gauge.

When the guide block is located in the horizontal groove, the monitoring cylinder is located inside the vent pipe. A venting groove is also provided on the outer circumference of the monitoring cylinder along the axial direction. The bottom of the water storage tank is circular, and a drainage channel is provided between the center of the bottom and the drainage hole. The bottom of the drainage channel is sloping, and the drainage hole is located at the lower end of the sloping surface.

[0006] The positive effects of this utility model are as follows: The secondary water supply storage tank described in this utility model, which ensures continuous water supply, has a foldable sterilization and disinfection mechanism installed inside the storage tank.

When not in use, it can be folded and stored in the center of the water tank, avoiding interference with the cleaning operation of the staff by traditional fixed disinfection devices. This not only improves cleaning efficiency but also ensures the comprehensive cleaning and disinfection quality inside the storage tank. At the same time, the ultraviolet germicidal lamps can effectively kill bacteria, viruses, and other microorganisms in the water, improve water quality safety, and ensure the hygiene of the water supply.

[0014] The present invention describes a secondary water supply storage tank that ensures continuous water supply, such as... Figure 1 As shown, it includes a water storage tank 1 located above the ground. The water storage tank 1 is used to temporarily hold a certain amount of water. When the water supply network is interrupted, the water inside is used for normal use. After the water supply is restored, water is stored in the tank.

[0015] A pump house 2 is installed on one side of the water storage tank 1. A water pump 3 is installed inside the pump house 2. The inlet of the water pump 3 is connected to the interior of the water storage tank 1 via a pumping pipe 4. A municipal water supply pipe 5, connected to the interior of the water storage tank 1, is also installed inside the pump house 2. During normal water supply, the municipal water supply pipe 5 replenishes water to the water storage tank 1, and the water pump 3 pumps water out of the water storage tank 1 for normal use. During this process, the water level in the water storage tank 1 is always maintained within a set height range. When the municipal water supply is interrupted, the water pump 3 pumps out the water stored in the water storage tank 1 for emergency use. After the water supply is restored, the water stored in the water storage tank 1 can be replenished simultaneously with normal water supply.

[0016] The upper part of the water storage tank 1 is equipped with an inspection port 6 and a vent pipe 7. A cover 8 is installed on the top of the vent pipe 7. After the water inside the water storage tank 1 is drained, the inspection port 6 allows personnel to enter the tank for inspection, maintenance, or cleaning. The vent pipe 7 ensures pressure balance between the inside and outside of the water storage tank 1, allowing for the smooth expulsion of internal air or the intake of external air when the water level changes. The cover 8 prevents external debris from entering the water storage tank 1 through the vent pipe 7 and contaminating the water. To ensure normal drainage of the water inside the tank, a closable drain hole 9 is provided on one side of the bottom of the water storage tank 1.

[0017] The top of the inner cavity of the water storage tank 1 is equipped with a foldable sterilization and disinfection mechanism. The sterilization and disinfection mechanism can be more evenly distributed in the tank during normal water supply to achieve large-area disinfection operations. When it is necessary for staff to enter the tank for cleaning, the sterilization and disinfection mechanism can be gathered and stored in the center to avoid interference with the staff inside.

[0018] like Figure 2 As shown, the sterilization and disinfection mechanism includes a disc 10 mounted on the top wall of the water storage tank 1. Several first connecting rods 11 arranged in a circular pattern are hinged to the disc 10, and a second connecting rod 12 is hinged to the end of each first connecting rod 11 away from the disc 10. Each first connecting rod 11 has a hanging ring 13, and the top wall of the water storage tank 1 has a hook 14 corresponding to the hanging ring 13. An ultraviolet germicidal lamp 15 is mounted on the second connecting rod 12.

[0019] During normal water supply, the ultraviolet germicidal lamps 15 sterilize and disinfect the water in the pool. At this time, the first connecting rod 11 is arranged horizontally and closely attached to the top wall of the pool. Under the action of gravity, the second connecting rod 12 is arranged vertically, and each ultraviolet germicidal lamp 15 is also arranged vertically and evenly distributed around the inside of the pool, which can form a more comprehensive coverage of the pool and thus improve the sterilization and disinfection effect.

[0020] When staff need to enter the pool for cleaning, after draining the water, hook 14 is separated from hanging ring 13. Second link 12 can then rotate to connect to first link 11. First link 11 and second link 12 are located at the bottom of disc 10 and are in a converged, retracted state, without interfering with the cleaning operations of staff inside. To achieve this state transition, the following steps are required: first, remove hanging ring 13 from hook 14; then, rotate first link 11 around the hinge point on disc 10, and simultaneously rotate second link 12 around the hinge point on first link 11. The rotation directions of first link 11 and second link 12 are opposite. Figure 3 As shown, the first link 11 and the second link 12 are finally stored at the bottom of the disc 10, freeing up the remaining space inside the pool to facilitate thorough cleaning by the staff inside.

[0021] Furthermore, in order to achieve the installation of the ultraviolet germicidal lamp 15 on the second connecting rod 12, such as... Figure 4 As shown, a quartz glass tube 32 is fixedly installed on the second connecting rod 12, and the ultraviolet germicidal lamp 15 is located inside the quartz glass tube 32. The quartz glass tube 32 can provide installation space for the ultraviolet germicidal lamp 15, and the quartz glass also allows the internal ultraviolet rays to shine outward, so as to achieve the corresponding sterilization and disinfection function.

[0022] To achieve waterproofing, a detachable top cover 16 is threaded onto the upper end of the quartz glass tube 32. A sealing ring 17 is installed between the top cover 16 and the quartz glass tube 32. A through hole is also provided on the top cover 16 to allow the power cord 18 to extend into, and a sealing plug 19 that mates with the power cord 18 is installed in the through hole. The sealing ring 17 and the sealing plug 19 create a relatively sealed waterproof space inside the quartz glass tube 32 for underwater use. The power cord 18 can be located inside the first connecting rod 11 and the second connecting rod 12 and is not affected by rotation or bending. The quartz glass tube 32 is located inside the second connecting rod 12 in its vertical position. When the second connecting rod 12 rotates to approach and retract towards the first connecting rod 11, the quartz glass tube 32 will not obstruct or interfere with the first connecting rod 11.

[0023] By fixing a quartz glass cylinder 32 to the second connecting rod 12 and installing an ultraviolet germicidal lamp 15, the ultraviolet germicidal lamp is protected from water corrosion and is easy to disassemble, replace, and maintain, thus improving the reliability and service life of the sterilization mechanism. Meanwhile, the design of the sealing ring 17 and sealing plug 19 effectively prevents water from entering the power cord interface, ensuring the safe operation of the circuit.

[0024] Furthermore, in order to connect and fix the first connecting rod 11 and the second connecting rod 12 in the sterilization and disinfection mechanism when it is in the folded storage state, the length of the first connecting rod 11 is greater than the length of the second connecting rod 12. A plug 20 is installed at the end of the second connecting rod 12, and a corresponding insertion hole 21 is opened on the first connecting rod 11 to cooperate with the plug 20. When the second connecting rod 12 rotates and approaches the first connecting rod 11, the plug 20 can enter the insertion hole 21 to realize the connection between the second connecting rod 12 and the first connecting rod 11.

[0025] The first link 11 and the second link 12 are detachably connected via the insert 20 and the insertion hole 21, making the folding and unfolding of the sterilization and disinfection mechanism simpler and faster, and improving operational efficiency. At the same time, this design also facilitates the individual replacement or repair of the sterilization and disinfection mechanism, reducing maintenance costs.

[0026] Furthermore, in order to monitor various data of the water in the pool and ensure water safety, a vertically movable monitoring cylinder 22 is installed inside the water storage tank 1, corresponding to the position of the vent pipe 7. The monitoring cylinder 22 cooperates with the cavity inside the vent pipe 7, and the vertical movement of the monitoring cylinder 22 is guided by the vent pipe 7. Water quality testing equipment can be placed inside the monitoring cylinder 22. During normal water supply, the monitoring cylinder 22 is located at the lowest position of the vent pipe 7, in the water, to monitor various data. When it is necessary to clean the inside of the pool, the monitoring cylinder 22 and the testing equipment inside can be moved upward along the vent pipe 7 to avoid interfering with the cleaning operations of the staff inside.

[0027] One of the monitoring cylinders 22 is equipped with a pH detection probe 23, an ORP detection probe 24, and a turbidity detection probe 25 to monitor water quality. The other monitoring cylinder 22 is equipped with an electronic level gauge 26 to monitor the water level in the tank. An electric control valve 33 is installed on the municipal water supply pipe 5. The electronic level gauge 26 is connected to the electric control valve 33 through a control circuit. When the water level in the tank is too low, the electric control valve 33 is opened to replenish water. When the water level in the tank is within the normal height range, the electric control valve 33 is closed to stop the internal water supply.

[0028] Furthermore, in order to achieve the vertical lifting and lowering of the monitoring cylinder 22 within the vent pipe 7 and the corresponding positional limits, such as... Figure 5 and Figure 6 As shown, the inner circumferential wall of the vent pipe 7 is provided with a vertical groove 27 and a horizontal groove 28 that are connected to each other. The outer circumference of the monitoring cylinder 22 is provided with a guide block 29 that cooperates with the vertical groove 27 and the horizontal groove 28. When the guide block 29 is located at the bottom of the vertical groove 27, the monitoring cylinder 22 is located inside the water storage tank 1. When the guide block 29 is located inside the horizontal groove 28, the monitoring cylinder 22 is located inside the vent pipe 7.

[0029] During normal water supply, the water in the pool needs to be monitored. At this time, the guide block 29 is located at the bottom of the vertical groove 27, and the monitoring cylinder 22 is located in the water. The internal detection equipment can perform normal monitoring functions. When cleaning is required, after draining the water, the staff enters the pool and pushes the monitoring cylinder 22 upward, allowing the guide block 29 to move upward along the vertical groove 27. When the guide block 29 moves to the top of the vertical groove 27, the monitoring cylinder 22 is rotated horizontally, and the guide block 29 can then enter the horizontal groove 28 from the vertical groove 27. The horizontal groove 28 is used to position and hoist the monitoring cylinder 22. The monitoring cylinder 22 is located inside the vent pipe 7, which also avoids interfering with the staff's cleaning operations.

[0030] By installing a liftable monitoring cylinder 22 inside the water storage tank 1, and equipping it with various water quality detection probes and an electronic level gauge 26, real-time monitoring of water quality and level is achieved. This provides a reliable basis for timely adjustment of the opening of the electric control valve 33 and control of the water inflow into the water storage tank, ensuring the continuity and stability of the water supply. Simultaneously, the monitoring cylinder 22, through the cooperation of the guide block 29 with the vertical groove 27 and horizontal groove 28 on the inner wall of the vent pipe 7, allows for flexible lifting and lowering inside and outside the water storage tank, without affecting water quality monitoring or interfering with cleaning operations within the tank.

[0031] The monitoring cylinder 22 is fitted with the inner cavity of the vent pipe 7 and can realize the vertical movement of the monitoring cylinder 22. In order to prevent the monitoring cylinder 22 from completely blocking the vent pipe 7 and causing the vent pipe 7 to lose its ventilation function, a ventilation groove 30 is also provided on the outer periphery of the monitoring cylinder 22 along the axial direction. The ventilation groove 30 is arranged circumferentially and does not interfere with the guide block 29.

[0032] Furthermore, to facilitate the cleaning and removal of waste from the pool, such as... Figure 7 As shown, the bottom surface of the water storage tank 1 is circular, and a drainage groove 31 is provided between the center of the bottom surface and the drainage hole 9. The bottom surface of the drainage groove 31 is inclined, and the drainage hole 9 is located at the lower end of the inclined surface.

[0033] The bottom of the water storage tank is designed to be circular with a drainage channel 31, which facilitates the rapid collection and discharge of accumulated water or waste, improving drainage efficiency. The drainage hole 9 is located at the lower end of the slope of the drainage channel 31, ensuring smooth and thorough drainage and further protecting the cleanliness and hygiene of the water storage tank.

[0034] Traditional secondary water supply systems still pose hygiene and safety risks. Currently, there are two main modes of secondary water supply for railway stations. One mode involves direct supply from the municipal water network daily, with secondary water supply activated when pressure is insufficient or during temporary water outages. This involves supplying water stored in a reservoir to the station. However, because the reservoirs hold water for extended periods and are not regularly flushed and replenished, the water in these temporarily activated reservoirs often contains water that has been stored for a long time, resulting in severely excessive levels of various hygiene indicators. The other mode involves pressurizing the municipal water supply through a secondary water supply reservoir for daily use. The reservoir is regularly disinfected with chlorine-containing disinfectants. This method requires higher standards for daily management, maintenance of disinfection facilities, and adherence to regulations.

[0035] Currently, most railway secondary water supply reservoirs are non-sealed underground concrete tanks, which are prone to scale and algae buildup on their inner walls, promoting microbial growth. The structure and supply mode of the secondary water supply system also make cleaning and disinfection of these tanks quite complex. Furthermore, the concrete structure poses a risk of sewage seepage, thus requiring a high level of environmental control. Secondary water supply equipment requires regular manual cleaning. Management of the secondary water supply system also suffers from inadequate personnel management, insufficient operation and maintenance, and non-standard cleaning and disinfection practices, leading to frequent exceedances of water quality standards.

[0036] To address the aforementioned issues, the pool is constructed entirely above ground, avoiding the risk of sewage seepage and reducing environmental impact. The drainage hole 9 also facilitates the emptying of stored water. The ultraviolet germicidal lamp 15 effectively enhances the quality of sterilization and disinfection. It can also be used in conjunction with the periodic addition of disinfectant to the inspection port 6 for auxiliary disinfection. The water quality monitoring equipment within the monitoring cylinder 22 enables real-time monitoring of the water quality, preventing continued water supply if water quality exceeds standards.

[0037] Furthermore, improvement plans can be proposed to address the hygiene issues existing in secondary water supply systems on railway stations and trains. These plans involve structural modifications, process improvements, and enhancements to the hygiene of secondary water supply systems, addressing aspects such as facilities and equipment, cleaning and disinfection, personnel management, and hygiene indicators. This will ensure the safety and hygiene of drinking water in stations and trains. Additionally, a smart water management system can be designed to enable remote real-time monitoring, ensuring normal equipment operation, improving remote management efficiency, and reducing manpower investment in operation and maintenance. Based on the research findings, suitable sites can be selected for practical modifications to further optimize the system design and generate replicable engineering construction experience. This will ensure the research results are applicable, replicable, and scalable, striving to achieve the transformation and application of research results. The goal is to promote a new model of railway station and train secondary water supply systems to all railway stations, providing hygiene and technical support for the design of new and renovated station secondary water supply systems, contributing to the improvement of water quality and hygiene in stations, and providing new economic growth points for equipment manufacturers and renovation contractors.

[0038] Its main research areas can be categorized into the following two directions:

It will also meet long-term water supply needs. This will ensure the quality and stability of the station and vehicle secondary water supply, reduce waste, and achieve real-time monitoring of the secondary water supply system's operation.

[0044] (3) Optimize the design of water tanks and pipelines to reduce the resistance and pressure loss of the pipeline network and improve the energy efficiency of the water supply system. Also consider using high-efficiency and energy-saving water pumps to improve the operating efficiency and energy-saving performance of the water supply system. For example, select water pumps with variable frequency speed control function, which can be intelligently controlled according to actual water supply needs to reduce energy consumption.

[0045] Explore the introduction and application of 3D technology and new materials and processes in improving railway water supply systems.

The system is planned to consist of three parts: an integrated intelligent pump station and self-flushing equipment, a water storage and supply system, and a smart water system. It has three operating modes: direct supply mode from the municipal water network, water storage tank supply mode, and water tank periodic self-flushing mode, to ensure the water quality of the water from the water storage tank and ensure constant pressure water supply. An energy-saving in-line pump and a dedicated constant pressure control cabinet with full frequency conversion are introduced, and backup equipment is also provided; an electrical contact pressure gauge is installed at the front end of the new equipment to ensure the stability of the secondary water supply at the station and vehicle points, prevent water supply interruption, and effectively protect the water pump; a pressure sensor is installed at the outlet to monitor the outlet pressure in real time, and the frequency conversion constant pressure water supply is regulated by the intelligent control system; a comprehensive overpressure protection device is configured to ensure the stable operation of the system; the new equipment connects the secondary water supply point at the station and vehicle and the pressurized water tank at the same time, which not only ensures energy-saving requirements but also maintains the constant water quality of the pool; a smart water system is adopted to realize remote intelligent management and control of the entire water supply process.
