Description

Technical Field

[0001] This invention belongs to the technical field of tunnel piston wind utilization, specifically relating to a chain-gear type power generation device based on tunnel piston wind power. Background Technology

[0002] With the rapid expansion of transportation networks, the construction mileage of railway and highway tunnels continues to increase. When trains pass through tunnels at high speed, a significant "piston wind" is generated due to the air compression effect. This process is accompanied by the release of a large amount of kinetic energy. Moreover, this type of wind energy has the characteristics of strong directionality and the frequency of occurrence is synchronized with the train operation cycle. It is an underutilized idle renewable energy source.

[0003] During tunnel operation, facilities such as lighting systems, environmental monitoring equipment, and emergency communication devices rely on the power grid or backup power for a long time. This not only increases the consumption of traditional fossil energy, but also causes problems such as insufficient power grid coverage in remote tunnels and low reliability of emergency power supply, which is contrary to the current development trend of green, low-carbon, energy-saving and emission-reduction.

[0004] Currently, although there are a few explorations of energy recovery from piston wind in tunnels, they all have obvious limitations: First, the wind speed and pressure of piston wind fluctuate dynamically with the train's operating status, and existing direct-drive power generation structures are difficult to match the rated speed of the generator, resulting in low power generation efficiency; Second, the tunnel interior space is small and installation conditions are limited, and traditional transmission structures are large in size and have poor stability, which are insufficient to adapt to the complex working conditions of the tunnel and cannot achieve efficient adaptation to the tunnel space; Third, existing devices are not well adapted to the intermittent characteristics of piston wind, and cannot output electrical energy stably, making it difficult to meet the continuous power supply needs of various tunnel facilities.

[0005] Guided by the "dual carbon" goal, the recycling and utilization of renewable energy has become an important direction for upgrading transportation infrastructure. Tunnel piston wind, as naturally generated waste kinetic energy during train operation, can be efficiently recycled and utilized to reduce energy costs in tunnel operation and enhance the autonomy and environmental friendliness of tunnel energy supply. Therefore, there is an urgent need to develop a power generation technology that is compact, has stable transmission efficiency, and is adapted to the confined space of tunnels and the dynamic characteristics of piston wind, in order to overcome the shortcomings of existing technologies. Summary of the Invention

[0006] This invention provides a chain-gear type power generation device based on tunnel piston wind power, solving the technical problems of low power generation efficiency, poor spatial adaptability, and unstable power supply in existing tunnel piston wind power generation devices. It achieves efficient and stable recovery of tunnel piston wind kinetic energy, providing reliable green power supply for tunnel operation facilities. Simultaneously, it effectively recovers train kinetic energy, has a simple structure, occupies little space, requires no major modifications to existing tunnels, can be directly installed and used, and is easy to maintain.

[0007] To achieve the above-mentioned objectives, this invention provides a chain-gear type power generation device based on tunnel piston wind power, comprising a chain, gears, telescopic springs, gear fixing rods, rotating shafts, generators, generator fixing plates, generator fixing rods, spring clip fasteners, rigid constraint rods, rigid support rods, movable curved panels, fixed telescopic rods, energy storage devices, and fixed splicing devices connected to the tunnel arch.

[0008] The chain connects to multiple gears mounted on a gear fixing rod. The gear fixing rod is installed on the tunnel arch surface via a fixing splicing device connected to the tunnel arch surface, providing fixed support for the chain and gears. The telescopic spring is located at the end of the gear fixing rod extending into the tunnel and is connected to the movable curved panel, used to assist the movable curved panel in returning to its original position. One end of the rotating shaft is installed on the shaft of the gear, and the other end is connected to a generator to realize the conversion of mechanical energy into electrical energy. The generator is installed on a generator fixing plate and fixed to the tunnel arch surface via a generator fixing rod and a fixing splicing device connected to the tunnel arch surface. The generator is connected to an energy storage device via an electric wire to realize the storage of electrical energy. The spring clip fastener device is fixed to the movable curved panel via a rigid constraint rod and a rigid support rod, and is adjacent to the chain, realizing the phased transfer of kinetic energy by tightening / loosening the chain. The movable end of the fixed telescopic rod is connected to the movable curved panel, and the fixed end is installed on the tunnel arch surface via a fixing splicing device connected to the tunnel arch surface, providing guidance and support for the movement of the movable curved panel.

[0009] The power generation system of this invention is an independent unit structure, and multiple units can be arranged longitudinally and laterally on the tunnel arch surface to improve the utilization rate of piston wind kinetic energy. The chain drives multiple gears to rotate, providing continuous power to the generator; the telescopic spring, after being compressed by the wind, assists in the rebound of the movable curved panel when the external wind weakens, thereby realizing the recovery of kinetic energy on the return trip; the movable curved panel adopts a curved surface structure to increase the windward area of ​​the piston wind, achieving stable kinetic energy recovery and transmission.

[0010] The present invention comprises multiple rotating shafts, generators, and generator mounting plates. Each generator is driven independently by a rotating shaft, and multiple generators work together to generate electricity, thereby increasing the overall power output.

[0011] The spring clip fasteners of the present invention are of two types and are located on both sides of the chain respectively. The left spring clip fastener drives the chain to rotate clockwise by moving outward along the tunnel radially, and the right spring clip fastener drives the chain to rotate clockwise by moving inward along the tunnel radially, thereby realizing continuous power generation in both the forward and return phases.

[0012] The left-side elastic clip is a right-angled shape with the vertical wing pointing inwards. A T-shaped pressing handle is located at the contact recess in the middle of the inner side of the horizontal wing. The vertical axis of the T-shaped pressing handle is connected to one end of the right-angle pressure rod, which is supported by the vertical compression elastic clip. When the T-shaped pressing handle is not under pressure, the other end of the right-angle pressure rod is engaged in the reserved hole in the horizontal movable rod, and the right-angle pressure rod remains closed. When the T-shaped pressing handle is under pressure, the end of the right-angle pressure rod connected to it is compressed, while the other end is pulled out of the reserved hole in the horizontal movable rod. The horizontal compression elastic clip connected to the horizontal movable rod will then pop out the chain buckle, thereby tightening the chain.

[0013] The right-side elastic clip of this invention is a right-angled shape with the vertical wing pointing outwards. A T-shaped pressing handle is provided at the contact recess in the middle of the outer side of the horizontal wing. A rigid support rod through hole is reserved next to the contact recess. The handle shaft of the T-shaped pressing handle is connected to one end of the right-angle pressure rod, which is supported by the vertical compression elastic clip. When the T-shaped pressing handle is not under pressure, the other end of the right-angle pressure rod is engaged in the reserved hole in the horizontal movable rod, and the right-angle pressure rod remains closed. When the T-shaped pressing handle is under pressure, the end of the right-angle pressure rod connected to it is compressed, while the other end is pulled out of the reserved hole in the horizontal movable rod. The horizontal compression elastic clip connected to the horizontal movable rod will pop out the chain buckle, thereby tightening the chain.

[0014] The rigid support rods of the present invention are provided with rigid support rod contact balls at their ends. The rigid support rod contact ball at the end of the left rigid support rod is positioned without pressure in the contact recess of the T-shaped pressing handle on the inner side of the horizontal wing of the elastic clip fastener. The rigid support rod on the right passes through the rigid support rod through hole, and its end rigid support rod contact ball is positioned without pressure in the contact recess of the T-shaped pressing handle on the outer side of the horizontal wing of the elastic clip fastener.

[0015] The left-side elastic clip of this invention drives the chain to rotate clockwise by moving radially outward along the tunnel. When the left-side elastic clip moves radially outward along the tunnel, it grips the chain to achieve kinetic energy transmission; when it moves radially inward along the tunnel, the chain is released because the T-shaped pressing handle is not under force, thus preventing the chain from being locked and unable to move.

[0016] The right-side elastic clip of this invention drives the chain to rotate clockwise by moving radially inward along the tunnel. When the right-side elastic clip moves radially inward along the tunnel, it grips the chain to achieve kinetic energy transmission. When it moves radially outward along the tunnel, the chain is released because the T-shaped pressing handle is not under force, thus preventing the chain from being locked and unable to move.

[0017] The rigid support rods on both sides are connected to the movable curved panel by hinges, ensuring that the rigid support rods move synchronously with the movable curved panel.

[0018] Compared with the prior art, the technical solution of the present invention has the following advantages: 1. This invention employs the principle of mechanical transmission to achieve continuous power generation in two stages: the piston wind's initiation and return. When the train enters the tunnel, the compressed air around and in front of it pushes the movable curved panel outward along the tunnel's radial direction, thereby driving the gears to rotate and generating electricity. After the train passes a certain position in the tunnel, the air pressure inside the tunnel decreases. Under the influence of gravity, the elasticity of the extension spring, and the air pressure difference, the movable curved panel moves inward along the tunnel's radial direction to return to its original position, simultaneously driving the gears to rotate again and generating electricity a second time. This effectively improves the recovery efficiency of the tunnel's piston wind kinetic energy.

[0019] 2. This invention uses multiple generators to generate electricity in coordination and combines them with an energy storage device to store electrical energy, which solves the inherent voltage and power fluctuation problems of piston wind power generation. By storing and regulating the intermittently generated electrical energy, a stable and reliable power supply is finally formed, which can be directly used for power grid construction or to supply power to various facilities such as tunnel lighting, environmental monitoring, and emergency communication, thereby improving the autonomy and reliability of tunnel power supply.

[0020] 3. The movable curved panel of the present invention adopts a curved surface structure, which effectively increases the windward area of ​​the piston wind and realizes stable piston wind kinetic energy transmission. Moreover, the overall structure is compact and occupies little space. It does not require major modification to the existing tunnel. It can be directly installed through a fixed splicing device with the tunnel arch surface. The installation and maintenance are easy and it is suitable for the narrow installation space and complex working conditions of the tunnel.

[0021] 4. The power generation system of the present invention is an independent unit structure. Multiple units can be flexibly arranged longitudinally and laterally on the tunnel arch surface according to the actual size of the tunnel and the piston wind intensity, so as to realize flexible adjustment of power generation and adapt to tunnels of different specifications and traffic density, and has a wide range of applications.

Detailed Implementation

[0024] The technical solution of the present invention will be described in detail below with reference to the accompanying drawings and specific embodiments. The scope of protection of the present invention is not limited to the following embodiments.

[0025] A chain-gear type power generation device based on tunnel piston wind power. A chain connects multiple gears mounted on a gear fixing rod, transmitting power from the movable curved panel to the gears. A telescopic spring is located at the end of the gear fixing rod extending into the tunnel and connected to the movable curved panel, assisting in the panel's return to its original position and enhancing the power generation during the return stroke. The generator drives a rotor to rotate and generate electricity via a rotating shaft, with all power connected to an energy storage device via wires. A spring-loaded fastener device is fixed to the movable curved panel by rigid constraint rods and rigid support rods, allowing power generation during both the forward and return strokes by loosening / tightening the chain. The movable curved panel increases the windward area, achieving stable kinetic energy recovery.

[0026] like Figure 1-5As shown, a chain-gear type power generation device based on tunnel piston wind power includes a chain 1, gears 2, a telescopic spring 3, a gear fixing rod 4, a rotating shaft 5, a generator 6, a generator fixing plate 7, a generator fixing rod 8, a spring clip fastener 9, a rigid constraint rod 10, a rigid support rod 11, a movable curved panel 12, a fixed telescopic rod 13, an energy storage device 14, and a fixed splicing device 15 connected to the tunnel arch. The chain 1 connects to multiple gears 2 mounted on the gear fixing rod 4, and the gear fixing rod 4 is mounted to the tunnel arch via the fixed splicing device 15. The telescopic spring 3 is located on the gear fixing rod. 4. The end extending into the tunnel is connected to the movable curved panel 12; one end of the rotating shaft 5 is installed on the shaft of the gear 2, and the other end is connected to the generator 6; the generator 6 is installed on the generator fixing plate 7, and is fixed to the tunnel arch surface by the generator fixing rod 8 and the fixed splicing device 15 of the tunnel arch surface. At the same time, the generator 6 is connected to the energy storage device 14 through the wire; the elastic fastener device 9 is fixed to the movable curved panel 12 by the rigid constraint rod 10 and the rigid support rod 11, and is adjacent to the chain 1; the movable end of the fixed telescopic rod 13 is connected to the movable curved panel 12, and the fixed end is installed on the tunnel arch surface by the fixed splicing device 15 of the tunnel arch surface.

[0027] The power generation system of the present invention is an independent unit, and multiple units can be arranged longitudinally and laterally on the tunnel arch.

[0028] like Figure 2 As shown, the telescopic spring 3 of the present invention, after being compressed by wind force, helps to spring back the movable curved panel 12 when the external wind force weakens.

[0029] like Figure 2 As shown, the movable curved panel 12 of the present invention moves outward along the tunnel radially under the action of wind. When the external wind weakens, it returns to its original position along the tunnel radially under the combined action of gravity and the telescopic spring 3.

[0030] like Figures 2-4 As shown, the left-side spring clip fastener 9 of the present invention is a right-angled shape with the vertical wing pointing inward. A T-shaped pressing handle 93 is provided at the contact recess 92 in the middle of the inner side of the horizontal wing. The handle shaft of the T-shaped pressing handle 93 is connected to one side of one end of the right-angle pressing rod 94, and the other side of the right-angle pressing rod 94 is supported by the vertical compression spring clip 95. When the T-shaped pressing handle 93 is not under pressure, the other end of the right-angle pressing rod 94 is engaged in the reserved hole in the horizontal movable rod 97, and the right-angle pressing rod 94 remains in a closed state; when the T-shaped pressing handle 93 is under pressure, the end of the right-angle pressing rod 94 connected to it is compressed, and the other end is pulled out of the reserved hole in the horizontal movable rod 97. A chain buckle 98 is installed on the end of the horizontal movable rod 97 facing the chain 1, and a horizontal compression spring clip 96 is installed on the other end.

[0031] like Figures 2-4As shown, the right-side spring clip fastener 9 of the present invention is a right-angled shape with the vertical wing pointing outwards. A T-shaped pressing handle 93 is provided at the contact recess 92 in the middle of the outer side of the horizontal wing. A rigid support rod through hole 91 is reserved next to the contact recess 92. The handle shaft of the T-shaped pressing handle 93 is connected to one side of one end of the right-angle pressing rod 94, and the other side of the right-angle pressing rod 94 is supported by the vertical compression spring clip 95. When the T-shaped pressing handle 93 is not under pressure, the right-angle pressing rod 94 is engaged in the reserved hole in the horizontal movable rod 97, and the right-angle pressing rod 94 remains closed. When the T-shaped pressing handle 93 is under pressure, the end of the right-angle pressing rod 94 connected to it is compressed, and the other end is pulled out of the reserved hole in the horizontal movable rod 97. A chain buckle 98 is installed on the end of the horizontal movable rod 97 facing the chain 1, and a horizontal compression spring clip 96 is installed on the other end. like Figure 5 As shown, the rigid support rod 11 of the present invention is provided with a rigid support rod contact ball 111 at each end. The rigid support rod contact ball 111 on the left side is disposed without pressure in the contact recess of the T-shaped pressing handle 93 on the inner side of the horizontal wing of the elastic clip fastener 9; the rigid support rod 11 on the right side passes through the rigid support rod through hole 91, and the rigid support rod contact ball 111 at the end is disposed without pressure in the contact recess of the T-shaped pressing handle 93 on the outer side of the horizontal wing of the elastic clip fastener 9.

[0032] like Figure 2 As shown, two types of elastic clip fasteners 9 are located on the left and right sides of the chain 1, respectively. The left and right rigid support rods 11 apply pressure to the left and right T-shaped pressing handles 93 during radial outward and inward movement along the tunnel, respectively, to control the relative movement between the elastic clip fasteners 9 and the chain. The left elastic clip fastener 9 grips the chain 1 when moving radially outward along the tunnel, causing the chain 1 to rotate clockwise; it loosens the chain 1 when moving radially inward along the tunnel, allowing relative movement. The right elastic clip fastener 9 grips the chain 1 when moving radially inward along the tunnel, causing the chain 1 to rotate clockwise; it loosens the chain 1 when moving radially outward along the tunnel, allowing relative movement. During the rotation of the chain 1, multiple gears 2 rotate, providing power to the generator 6. Multiple rotating shafts 5, generators 6, and generator mounting plates 7 are arranged, with each generator 6 driven independently by a rotating shaft 5. The rigid support rods 11 on both sides are connected to the movable curved panel by hinges, and move up and down along with the movable curved panel.

[0033] Combination Figures 1-5When a high-speed train passes through a tunnel, the air around and in front of the train is compressed due to the action of the train's piston, causing the movable curved panel 12 on the inner perimeter of the tunnel to move outward radially along the tunnel, along with the fixed telescopic rod 13, rigid constraint rod 10, and rigid support rod 11. At this time, the contact ball 111 of the left rigid support rod presses the T-shaped pressing handle 93 inside the elastic clip fastening device 9, which in turn causes one end of the vertical pressure rod 94 connected to the T-shaped pressing handle 93 to be compressed, while the other end is pulled out of the reserved hole of the horizontal movable rod 97. At the same time, under the pushing action of the horizontal compression elastic clip 95, the chain buckle 98 pops out and clamps the left chain. As for the contact ball 111 of the right rigid support rod, since it is located outside the horizontal wing of the elastic clip fastening device 9, it has no pressure on the right T-shaped pressing handle 93, and the right chain buckle 98 will not pop out, leaving the right chain in a free state. Therefore, as the rigid support rod 11 moves radially outward from the tunnel, the left elastic clip fastening device 9 rotates clockwise with the chain 1.

[0034] Combination Figures 1-5 When the train leaves a certain position in the tunnel, the piston action inside the tunnel weakens, the air pressure decreases, and the movable curved panel 12 moves radially inward along the tunnel under the action of gravity and the telescopic spring 3, moving together with the fixed telescopic rod 13, rigid constraint rod 10, and rigid support rod 11. At this time, the contact ball 111 of the right rigid support rod presses the T-shaped pressing handle 93 inside the elastic clip fastener device 9, causing one end of the vertical pressure rod 94 connected to the T-shaped pressing handle 93 to be compressed, while the other end is pulled out of the reserved hole of the horizontal movable rod 97. At the same time, under the pushing action of the horizontal compression elastic clip 95, the chain buckle 98 pops out and clamps the right chain. As for the contact ball 111 of the left rigid support rod, since it is located inside the horizontal wing of the elastic clip fastener device 9, it has no pressure on the left T-shaped pressing handle 93, the left chain buckle 98 will not pop out, and the left chain is in a free state. Therefore, as the rigid support rod 11 moves radially inward toward the tunnel, the elastic fastener device 9 on the right side carries the chain 1 and rotates clockwise.

[0035] Combination Figures 1-5When the train passes through a certain position in the tunnel, under the action of the piston wind pressure, the movable curved panel 12 moves outward radially along the tunnel, and the rigid support rod 11 moves outward together. The elastic clip fastener 9 on the left side rotates clockwise with the chain 1. When the train leaves a certain position in the tunnel, the piston wind pressure weakens, and the movable curved panel 12 moves inward radially along the tunnel and returns to its original position under the action of gravity and the telescopic spring 3. The rigid support rod 11 moves inward together, and the elastic clip fastener 9 on the right side rotates clockwise with the chain 1. As the chain 1 continues to rotate, the gear 2 also rotates, driving the rotating shaft 5 to rotate as well. The end of the rotating shaft 5 is connected to the internal coil of the generator, so that the generator can generate electricity when the gear 2 and the rotating shaft 5 rotate. The current generated by the generator is stored through the energy storage device 14 and then connected to the internal power grid of the tunnel to supply electricity for the tunnel.

[0036] The above description is only a preferred embodiment of the present invention and is not intended to limit the scope of protection of the present invention.
