Description

Technical Field

[0001] The utility model discloses a spiral type surge tank, belonging to the technical field of water conservancy and hydropower surge tanks. Background Art

[0002] In modern water conservancy projects, with the increasing complexity of long-distance water pipeline systems, effective water pressure regulation has become crucial for ensuring stable system operation. When pipelines cross mountains and rivers, surge tanks are required to balance the water pressure within the pipelines and ensure smooth and safe water flow. Currently, traditional surge tank technologies are primarily divided into two types: vertical and parallel.

[0003] Vertical surge tanks are widely used due to their simple structure and convenient construction. However, their limitations cannot be ignored: due to geological conditions and mountain height, vertical surge tanks have poor adaptability in complex terrain. When faced with high water pressure, the shaft wall is subjected to concentrated force, resulting in poor safety performance. Furthermore, the pressure-regulating effect is limited because the linear structure cannot fully disperse the water pressure. Parallel surge tanks are known for their strong adaptability to terrain, but their high construction cost, large surface area occupied, and construction complexity, coupled with the fact that horizontal shafts are prone to water and silt accumulation, which affects water flow efficiency and pressure regulation, constitute major challenges to their widespread application. Summary of the Invention

[0004] The utility model overcomes the shortcomings of the prior art and proposes a spiral pressure regulating well, comprising: a well, a main pipeline and a plurality of pressure relief devices;

[0005] The well is arranged spirally along the inside of the mountain to reduce the pressure of the water flow;

[0006] The lower end port of the well is in communication with the main pipeline;

[0007] The plurality of pressure relief devices are arranged in the shaft at preset distances;

[0008] The pressure relief device is a water blocking plate provided with a plurality of guide holes;

[0009] The water blocking plate is perpendicular to the center line of the well and the periphery thereof is in close contact with the inner wall of the well.

[0010] Preferably, the opening of the guide hole is adjustable.

[0011] Preferably, the slope of the winding path of the well is 5-15 degrees.

[0012] Preferably, the interval between two adjacent pressure relief devices is 10-30 meters.

[0013] Preferably, the shaft is cast with reinforced concrete.

[0014] Preferably, the inner wall of the shaft is coated with a waterproof coating.

[0015] Preferably, the waterproof coating is made of polyethylene material.

[0016] Preferably, a plurality of automatic monitoring systems are provided in the well for monitoring the water pressure changes in the well in real time.

[0017] Preferably, the cross-section of the well is circular or elliptical.

[0018] Compared with existing technologies, this utility model offers the following benefits: its spiral surge tank evenly distributes water pressure within the wellbore, effectively alleviating the concentrated pressure on the wellbore wall. This significantly reduces the risk of wellbore rupture and collapse, significantly improving the safety and stability of the overall structure. This feature is particularly suitable for high-pressure environments, ensuring the long-term and stable operation of the system.

[0019] Secondly, the built-in pressure relief device, another important safeguard for pressure dispersion, further refines and reduces the impact pressure of the water flow on the wellbore through its multiple adjustable diversion holes, enhancing the system's pressure resistance and impact resistance. This dual pressure dispersion mechanism works together to ensure that the surge tank of this utility model maintains excellent performance even in extreme water pressure conditions.

[0020] Furthermore, the spiral shaft design flexibly adapts to the complex terrain within the mountain, reducing topographical constraints on construction. This feature not only improves construction efficiency but also reduces project costs, making it possible to construct efficient and safe surge tanks even in complex geological conditions.

[0027] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0028] This embodiment provides a spiral surge tank, comprising: a tank 1, a main pipeline 2, and multiple pressure-reducing devices 3. The tank 1 spirals along the interior of a mountain to reduce water pressure. The lower end of the tank 1 is connected to the main pipeline 2. The multiple pressure-reducing devices 3 are arranged at predetermined intervals within the tank 1. The pressure-reducing devices 3 are water-blocking plates 3-1 with multiple diversion holes 3-2. The water-blocking plates 3-1 are perpendicular to the centerline of the tank 1, and their peripheries are tightly aligned with the inner wall of the tank 1. This spiral path extends the water flow path, reduces water pressure concentration, disperses pressure, and improves the stability of the tank wall.

[0029] Specifically, such as Figure 1-5 As shown, in this embodiment, the pressure-regulating well is arranged in a spiral manner, and its spiral diameter gradually increases with increasing height. It should be understood that the present invention is not limited to the spiral manner of the pressure-regulating well, and its spiral diameter may also gradually become smaller with increasing height, or the spiral arrangement may not change. In another embodiment, it may also be a wave-shaped arrangement. Its specific spiral manner is adjusted according to the geological conditions of the tunnel set up inside the mountain in the early stage of the project, and can be combined with temporary passages during the construction process to reduce the difficulty and cost of the project construction.

[0030] The present invention incorporates multiple pressure-reducing devices 3 within the wellbore 1. These devices are spaced at predetermined intervals. To further enhance the pressure-reducing effect of the surge tank, the devices 3 are specifically designed as water-blocking plates 3-1 with multiple flow-guiding holes 3-2. These plates 3-1 are perpendicular to the centerline of the wellbore 1, and their edges closely adhere to the inner wall of the wellbore 1, ensuring that the water flow is fully contacted and guided by the plates 3-1.

[0031] Furthermore, the interval between two adjacent pressure relief devices 3 is 10-30 meters.

[0032] Specifically, the distance between two adjacent pressure relief devices 3 is optimized to be between 10 and 30 meters. This configuration strategy ensures a stable, step-by-step pressure reduction within the wellbore 1 while avoiding unnecessary costs and pressure fluctuations caused by overly dense or sparse placement. Furthermore, the opening of the diversion holes 3-2 is adjustable.

[0033] Specifically, the opening of the guide hole 3-2 is designed to be adjustable so that it can be flexibly adjusted according to actual operating conditions to achieve the best pressure reduction effect.

[0034] Furthermore, the slope of the winding path of the shaft 1 is 5-15 degrees.

[0035] Shaft 1 spirals upward along the natural terrain of the mountain, with a precisely controlled slope between 5 and 15 degrees. This design angle ensures that the water flow slows naturally and gently within Shaft 1, avoiding the impact and pressure concentration caused by excessive flow. It also fully considers the construction difficulty and cost, allowing Shaft 1 to smoothly traverse the complex and varied mountain terrain.

[0036] Furthermore, the shaft 1 is cast with reinforced concrete.

[0037] During construction, Shaft 1 was cast using high-strength reinforced concrete to ensure structural stability and durability. This reinforced concrete not only provides sufficient compressive strength but also effectively resists groundwater erosion and geological fluctuations. The interior walls of Shaft 1 were meticulously treated to ensure a smooth surface, laying a solid foundation for subsequent coating applications.

[0038] Furthermore, the inner wall of the shaft 1 is coated with a waterproof coating.

[0039] In order to ensure that the shaft 1 can effectively resist the erosion of groundwater during long-term use and maintain the stability and durability of the structure, a high-quality waterproof coating is coated on the inner wall of the shaft 1.

[0040] Furthermore, the waterproof coating is made of polyethylene material.

[0041] Specifically, the waterproof coating on the inner wall of the well 1 in this embodiment is made of high-density polyethylene material. Those skilled in the art can also select other composite materials according to the actual engineering environment to enhance the corrosion resistance and durability of the well 1.

[0042] Furthermore, a plurality of automatic monitoring systems are provided in the well 1 for monitoring the water pressure changes in the well 1 in real time.

[0043] In order to monitor the water pressure changes in the well 1 in real time and ensure the safe and stable operation of the surge tank, the utility model sets up multiple automatic monitoring systems in the well 1. These systems are distributed in different positions of the well 1 and can fully cover all areas in the well 1 to achieve real-time monitoring and recording of key parameters such as water pressure and flow rate. The automatic monitoring system adopts advanced sensor technology and data transmission technology, which can accurately and timely collect and transmit monitoring data to the central control room. The staff can intuitively understand the operating status of the well 1 through the display screen and data analysis software in the central control room, and perform remote control and emergency treatment as needed.

[0044] Furthermore, the cross section of the hoistway 1 is circular or elliptical.

[0045] In the selection of cross-sectional shape, the present invention fully considers factors such as structural stability, hydrodynamic characteristics and construction convenience. After comprehensive comparison and analysis, it was finally determined that the cross-sectional shape of the well 1 is circular or elliptical. These two shapes not only have good force-bearing properties and can withstand large water pressure and lateral pressure, but also can optimize the flow state of water flow and reduce energy loss and resistance. At the same time, the circular or elliptical cross-sectional shape is also convenient for construction and installation. When pouring reinforced concrete, formwork support and pouring technology can be used to achieve precise cross-sectional shaping and surface smoothing. In addition, this shape is also convenient for subsequent coating construction and daily maintenance management.

[0046] The spiral surge tank of this utility model evenly distributes the water pressure within the wellbore 1, effectively alleviating the concentrated pressure on the wellbore wall, thereby greatly reducing the risk of wellbore rupture and collapse, and significantly improving the safety and stability of the overall structure. This feature is particularly suitable for high-pressure environments and ensures the long-term stable operation of the system.

[0047] Secondly, the built-in pressure relief device 3, another important safeguard for pressure dispersion, further refines and reduces the impact pressure of the water flow on the well 1 through its multiple adjustable diversion holes 3-2, thereby enhancing the system's pressure resistance and shock resistance. This dual pressure dispersion mechanism works together to ensure that the surge tank of the utility model maintains excellent performance even in extreme water pressure conditions.

[0048] Furthermore, the spiral shaft design flexibly adapts to the complex terrain within the mountain, reducing construction restrictions. This feature not only improves construction efficiency but also reduces project costs, making it possible to construct efficient and safe surge tanks in complex geological conditions.

[0049] The above shows and describes the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are merely preferred examples of the present invention and are not intended to limit the present invention. Various changes and improvements may be made to the present invention without departing from the spirit and scope of the present invention, and such changes and improvements fall within the scope of the present invention. The scope of protection claimed in the present invention is defined by the appended claims and their equivalents.
