Description

Technical Field

[0001] This utility model relates to the field of rinsing equipment, specifically a vacuum-powered integrated rinsing device. Background Technology

[0002] Regulating reservoirs play a vital role in municipal engineering, and during routine cleaning and maintenance, if the bottom debris, garbage, and sludge are not promptly flushed and cleaned after emptying, siltation and blockages can easily occur. Common flushing devices used for cleaning regulating reservoirs include vacuum flushing equipment.

[0003] A vacuum flushing device typically includes a water storage chamber, a vacuum diaphragm valve, a vacuum pump, and an electrical control system. When the level monitoring system detects a rise in water level, the control system activates the vacuum pump to create a vacuum in the water storage chamber, raising the water level to the flushing level. Subsequently, the control system opens the vacuum diaphragm valve, breaking the vacuum in the water storage chamber and enabling rapid flushing of the wastewater.

[0004] However, existing flushing equipment has limitations in its flushing methods and structure. Firstly, there are limitations in installation: current vacuum flushing technology generally relies on a dedicated concrete water storage chamber constructed concurrently with the main structure of the storage tank. This chamber requires additional civil engineering planning, construction, and space occupation, increasing not only the complexity and cost of the project but also making it difficult to easily modify or add this technology to existing storage tanks. Secondly, there are limitations in usage: common methods rely on simple water flushing, where the vertically falling water directly impacts the bottom of the tank or falls into the diversion channel, dispersing into the storage tank through impact. A large amount of energy is dissipated at the moment of impact, failing to be effectively converted into lateral sweeping kinetic energy, resulting in low flushing force and efficiency. Furthermore, it cannot work effectively when the storage tank itself has insufficient water or when external water supply is inconvenient, lacking emergency and enhanced cleaning methods. Utility Model Content

[0005] The purpose of this invention is to provide a vacuum-powered integrated flushing device, which is designed to solve technical problems such as insufficient flushing power, low energy utilization efficiency, and poor adaptability to working conditions. It provides a more efficient, economical, and more widely applicable integrated solution.

[0006] To achieve the above objectives, this utility model employs the following technical solution: A vacuum-powered integrated flushing device includes a flushing unit. The flushing unit includes a vacuum valve seat installed at the top of one end of a storage tank. The vacuum valve seat has an independent upper and lower air inlet chamber and a vacuum chamber. A vacuum diaphragm valve is installed between the air inlet chamber and the vacuum chamber. A downwardly extending water storage pipe is sealed to the bottom end of the vacuum valve seat. An air pipe connector communicating with the vacuum chamber is provided on the side wall of the vacuum valve seat. A water pipe connector is connected to the top end of the water storage pipe. A vacuum pump is connected to the air pipe connector. A water source with a water pump is connected to the water pipe connector. A sealing plate with an opening and closing action is provided at the bottom end of the water storage pipe.

[0007] The top of the vacuum valve seat is connected to a protective cover, which is made of a perforated plate and is connected to the air inlet chamber.

[0008] The bottom end of the water storage pipe is provided with a flushing port, which faces the storage tank and is inclined downward.

[0009] The bottom end of the water storage pipe is provided with a flushing port, which is a flat opening with a horizontal length, and the cross-sectional area of ​​the water storage pipe remains unchanged from top to bottom.

[0010] The water storage pipe comprises a straight cylindrical section, a first deformable section, a second deformable section, and a flat tube section, all integrally formed and connected from top to bottom. The straight cylindrical section is cylindrical. The top end of the first deformable section is a circular opening that connects to the bottom end of the straight cylindrical section. The bottom end of the first deformable section is a square opening that connects to the top end of the second deformable section. The top end of the second deformable section is a square opening corresponding to the bottom end of the first deformable section. The bottom end of the second deformable section is a flat opening with a length 3-5 times its width that connects to the flat tube section. The cross-sectional shape of the flat tube section remains unchanged. The bottom end of the flat tube section is provided with a flushing port. The flat tube section is an arc-shaped pipe that bends and extends towards the storage tank. The arc of the flat tube section is 45-80 degrees.

[0011] The cross-sectional areas of the straight section, the first deformed section, the second deformed section, and the flat tube section remain unchanged.

[0012] The curvature of the flat tube section is 65-75 degrees.

[0013] The bottom end of the water storage pipe is provided with a flushing port. The bottom side of the sealing plate is hinged to the bottom edge of the flushing port. A mounting post is fixed in the center of the outer side of the sealing plate. The bottom end of the mounting post extends downward from the bottom side of the sealing plate. A mounting bracket is provided in the center of the bottom side of the flat tube. A cylinder is hinged inside the mounting bracket. A cylinder rod is telescopically fitted at one end of the cylinder. The end of the cylinder rod is hinged to the bottom end of the mounting post.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: By replacing the fixed civil engineering structure with a water storage pipe integrated at the bottom of the valve seat, the rigid dependence of traditional vacuum flushing technology on pre-construction civil engineering conditions is broken, solving technical problems such as insufficient flushing power, low energy utilization efficiency, and poor adaptability to working conditions. Through innovative integration of vacuum energy storage and dual power replenishment systems, a set of efficient, reliable and intelligent integrated cleaning solutions is provided.

Detailed Implementation

[0021] The present invention will be further illustrated below with reference to specific embodiments. It should be understood that these embodiments are for illustrative purposes only and are not intended to limit the scope of the present invention. Furthermore, it should be understood that after reading the teachings of this invention, those skilled in the art can make various alterations or modifications to the present invention, and these equivalent forms also fall within the scope defined in this application.

[0022] Example: A vacuum-powered integrated flushing device This integrated flushing device includes a vacuum unit, a replenishment unit, and a flushing unit.

[0023] The vacuum unit mainly refers to the negative pressure system, specifically including a vacuum pump, gas pipelines, and a control cabinet. The vacuum pump is integrated into a housing or skid and can be used immediately upon connection to a power source. The vacuum pump is used to create a vacuum, forming a negative pressure inside the water storage pipe, thereby keeping external water stored inside.

[0024] The supplementary unit mainly refers to an additional water supply system, specifically including a water pump and water pipelines. The water pump is used to directly pump water into the water storage pipe when rinsing is required but there is no vacuum water storage condition, thereby ensuring the rinsing effect.

[0025] The vacuum pumps, air lines and control cabinets, as well as the water pumps and water lines mentioned above are all commonly used equipment in existing municipal rainwater facilities. They only need to meet the functions of vacuuming and pumping water. The specific selection will not affect the implementation of the solution.

[0026] The flushing unit includes a vacuum valve seat 1, which is fixedly installed at the top of one end of the storage tank. The bottom of the vacuum valve seat 1 is connected to a water storage pipe via a flange and a seal. The top of the vacuum valve seat 1 is connected to a protective cover 2, which is made of a perforated plate to prevent debris from being sucked in. A vacuum diaphragm valve is installed inside the vacuum valve seat 1. Specifically, the vacuum valve seat 1 has an independent upper and lower air inlet chamber and a vacuum chamber. The air inlet chamber is connected to the protective cover 2. The vacuum valve seat 1 connects the air inlet chamber and the vacuum chamber through the vacuum diaphragm valve. The water storage pipe is sealed and connected to the vacuum chamber to control the vacuum status inside the water storage pipe.

[0027] The vacuum valve seat 1 has an air pipe connector 3 on its side wall that communicates with the vacuum chamber, and a water pipe connector is connected to the top of the water storage pipe. The air pipe connector 3 connects to the vacuum pump via an air circuit, enabling control of the vacuum environment. The water pipe connector connects to the water pump and water source via a water circuit, allowing water to be injected. Both the air and water circuits can be made of flexible hoses.

[0028] The bottom end of the water storage pipe is close to the bottom of the storage tank. The water storage pipe includes a straight cylindrical part 4, a first deformable part 5, a second deformable part 6, and a flat tube part 7, which are integrally formed and connected from top to bottom.

[0029] The straight section 4 is cylindrical, and its top end is sealed to the vacuum cavity at the bottom of the vacuum valve seat 1 via a flange.

[0030] The top end of the first deformable part 5 is a circular opening and communicates with the bottom end of the straight cylindrical part 4, and the bottom end of the first deformable part 5 is a square opening and communicates with the top end of the second deformable part. The top of the second deformable part is a square opening that corresponds to the bottom of the first deformable part 5. The bottom of the second deformable part is a flat opening with a length 3-5 times its width, and it communicates with the flat tube part 7. The flat opening can be rectangular or oblong. The cross-section of the flat tube section 7 remains unchanged. The bottom end of the flat tube section 7 is provided with a flushing port 8. The flat tube section 7 is an arc-shaped tube that bends and extends towards the storage tank. The arc of the flat tube section 7 is 75 degrees, so that the flushing port 8 at the bottom end of the flat tube section 7 can flush water towards the storage tank and has a downward inclination of 15 degrees.

[0031] The cross-sectional area of ​​the water storage pipe remains constant from top to bottom regardless of changes in its cross-sectional shape. Therefore, it does not affect the water's falling velocity or potential energy.

[0032] Through the above structure, the cross-section of the water storage pipe changes from circular to square to rectangular / waist-shaped (flat opening) from top to bottom. The length of the flat opening is relative to the width of the storage tank, enabling water to be flushed out over a wider area, achieving lateral water distribution. Simultaneously, the cross-section of the water storage pipe remains constant from top to bottom, avoiding frictional losses and flow velocity reductions caused by cross-sectional changes, and preventing the absorption and loss of potential energy. Furthermore, the arc-shaped bend at the bottom effectively guides water into the tank, preventing the loss of potential energy due to vertical impact when water falls downwards from the storage chamber, thus avoiding insufficient flushing force. The slightly downward-sloping flushing outlet 8 effectively flushes both the inside and bottom of the tank, improving the cleaning effect.

[0033] A sealing plate 9 is provided at the flushing port 8, which can be sealed and closed. A sealing gasket is provided on the inner side of the sealing plate 9, and a mounting post 10 is fixed in the center of the outer side of the sealing plate 9. The bottom end of the mounting post 10 extends downward from the bottom side of the sealing plate 9. The bottom side of the sealing plate 9 is hinged to the bottom edge of the flushing port 8. A mounting bracket 11 is provided in the center of the bottom side of the flat tube section 7. The mounting bracket 11 is a U-shaped groove frame structure. A cylinder 12 is hinged inside the mounting bracket 11. A cylinder rod 13 is telescopically fitted at one end of the cylinder 12. The end of the cylinder rod 13 is hinged to the bottom end of the mounting post 10, thereby realizing the control of opening and closing of the sealing plate 9.

[0034] When the water level in the pool is insufficient to support vacuum water storage, or when the flushing effect is not ideal and the bottom of the pool still needs cleaning and maintenance (there is still silt or debris), the water pump is started and the sealing plate 9 is closed (the vacuum diaphragm valve remains open, and the water storage pipe is connected to the outside air) to store water in the water storage pipe. The water level is judged by the level gauge in the vacuum valve seat 1. After filling, the sealing plate 9 is opened to achieve supplementary flushing.

[0035] This vacuum-powered integrated flushing device achieves efficient, comprehensive, and intelligent cleaning of the storage tank. Its core effect is primarily reflected in its superior flushing performance. The device uses vacuum power to pre-store a large volume of water in a specially designed storage pipe, which is then released instantaneously, creating a powerful water flow. The storage pipe features a variable cross-section design with a constant cross-sectional area from top to bottom, smoothly transitioning from a circular shape to a flat opening. This structure ensures that the potential energy of the water flow is maintained to the maximum extent during its descent, avoiding frictional losses and flow rate reductions caused by abrupt changes in cross-section. The flat tube section 7 at the bottom is bent at a specific arc, causing the flushing outlet 8 to face inwards and tilt slightly downwards. This converts the enormous potential energy of the vertically falling water flow into a lateral flushing force with wide-angle coverage, achieving both wide-area water distribution along the width of the storage tank and effective impact on the tank bottom, significantly improving the ability to remove accumulated silt and debris.

[0036] Secondly, the device possesses high adaptability and controllability. Its integrated supplementary water supply unit can directly inject water into the storage pipe when the initial water level in the pool is insufficient or when further cleaning is required after the initial rinse, enabling continuous or supplementary rinsing and ensuring cleaning reliability under various working conditions. The intelligent sealing plate structure 9 at the 8 flushing inlets, controlled by hydraulic or pneumatic cylinders, allows for precise control of water storage and release timing. Combined with the liquid level monitoring within the vacuum valve seat 1, it achieves automated management of the rinsing process. The overall device adopts a modular integrated design, integrating major components such as the vacuum pump, water pump, and control cabinet into one unit. On-site installation is simple; only a connection to the power supply and pipeline is required for operation, significantly reducing the complexity of construction and maintenance.

[0037] Furthermore, this example, by highly integrating the "water storage" function into a flexibly arranged water storage pipe, fundamentally eliminates the need for a pre-constructed concrete water storage chamber, as required by traditional methods. This water storage pipe employs a variable cross-section design with a constant cross-sectional area from top to bottom, thus constituting a highly efficient energy storage and flow guiding structure, storing flushing water under vacuum. This not only simplifies the system configuration but also makes installation and deployment extremely flexible. It can be directly installed in existing or newly built regulating reservoirs without the need for complex civil engineering, significantly reducing initial construction difficulty, time, and cost, and can be widely used for the renovation of existing facilities. It should be noted that the above description is a further detailed explanation of this utility model in conjunction with specific embodiments, and should not be construed as limiting the specific implementation of this utility model to these descriptions. For those skilled in the art, various simple improvements and modifications can be made without departing from the concept of this utility model, and all such improvements and modifications should be considered within the scope of protection of this utility model.
