Description

Technical Field

[0001] The present invention relates to the technical field of access gates, and particularly to a gate system with an energy harvesting function.

Background Art

[0002] As the global society transitions towards sustainable energy solutions, traditional renewable energy systems such as wind turbines, solar panels, and hydroelectric power plants have made significant contributions to meeting energy demands by converting natural resources like wind, solar, and water energy into electricity. However, due to environmental, spatial, and infrastructure limitations, these systems also face numerous constraints. Wind turbines require high wind speeds, solar panels need continuous sunlight, and hydroelectric dams rely on abundant water resources, all of which often lead to severe environmental damage. These challenges have spurred an increasing interest in hybrid small-scale energy harvesting technologies.

[0003] Hybrid mechanical energy systems are a promising approach to urban energy harvesting. These technologies are particularly valuable in environments where traditional renewable energy is less feasible. The turnstiles commonly found in transportation hubs and commercial buildings present an untapped opportunity to generate mechanical energy from pedestrian movement. Although electromagnetic systems that convert rotational motion into electricity using magnets and coils already exist in the prior art, they face challenges such as mechanical complexity, high maintenance costs, and heat losses, which reduce their efficiency, especially in areas with high pedestrian traffic.

[0006] Preferably, at least three gate rods are provided on the rotating mechanism, and the gate rods are connected to the outer side of the rotating disc. Pedestrians can pass through by pushing the gate rods to make the rotating mechanism rotate.

[0007] Preferably, the energy conversion disc is arranged vertically, and a plurality of impact cavities are uniformly arranged in the energy conversion disc. Piezoelectric discs are arranged at both ends of each impact cavity, and a counterweight block is slidably arranged in the impact cavity. When the energy conversion disc rotates, the counterweight block slides back and forth in the impact cavity, and the counterweight block repeatedly impacts the piezoelectric discs at both ends of the impact cavity.

[0008] Preferably, a slip ring is arranged at the center of the energy conversion disc, and the slip ring is connected to the piezoelectric disc. The slip ring is used to collect the electrical energy generated by the piezoelectric disc.

Detailed Embodiment

[0022] In order to make the objectives, technical solutions and advantages of the present invention clearer and more understandable, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only for explaining the present invention and are not used to limit the present invention.

[0023] It should be noted that all directional indications (such as up, down, left, right, front, back...) in the embodiments of the present invention are only relative positions on the specified views, rather than absolute positions.

[0024] In addition, in the present invention, descriptions such as "first" and "second" are only for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the quantity of the indicated technical features. Thus, features defined with "first" and "second" may explicitly or implicitly include at least one of such features. In the description of the present invention, "a plurality" means at least two, such as two, three, etc., unless otherwise specifically defined.

[0025] Please refer to Figures 1 to 6 , the turnstile system with energy harvesting function of the present invention includes a turnstile box body 10, a rotatable rotating mechanism 20 is provided on the turnstile box body 10, and at least three turnstile rods 22 are provided on the rotating mechanism 20. Pedestrians can pass through by pushing the turnstile rods 22 to make the rotating mechanism 20 rotate.

[0026] The rotating mechanism 20 includes a rotating disk 21, the turnstile rods 22 are connected to the outside of the rotating disk 21, and an energy recovery mechanism is connected to the inside of the rotating disk 21. The energy recovery mechanism is used to convert mechanical energy into electrical energy.

[0027] The energy recovery mechanism includes a first gear 23, which is connected to a rotating disk 21. The rotation of the rotating disk 21 drives the rotation of the first gear 23.

[0028] The first gear 23 is meshed with at least two second gears 24. The rotation of the first gear 23 drives the rotation of the second gears 24.

[0029] The second gear 24 is concentrically connected with an energy conversion disk 25 through a connecting shaft. The energy conversion disk 25 is used to convert mechanical energy into electrical energy.

[0030] The first gear 23 is meshed with at least one third gear 26. The third gear 26 is concentrically connected with an energy recovery rod 27. The energy recovery rod 27 is connected with a power generation module 28. The power generation module 28 is used to convert mechanical energy into electrical energy. The power generation module 28 can adopt an electromagnetic generator.

[0031] The energy conversion disk 25 is vertically arranged. A plurality of impact cavities 251 are uniformly arranged in the energy conversion disk 25. Piezoelectric disks 253 are arranged at both ends of each impact cavity 251. A counterweight 252 is slidably arranged in the impact cavity 251. When the energy conversion disk 25 rotates, the counterweight 252 slides back and forth in the impact cavity 251. The counterweight 252 repeatedly impacts the piezoelectric disks 253 at both ends of the impact cavity 251. The piezoelectric disks 253 generate charges under the action of mechanical stress, thereby converting mechanical energy into electrical energy.

[0032] A slip ring 255 is arranged at the center of the energy conversion disk 25. The slip ring 255 is connected with the piezoelectric disks 253. The slip ring 255 is used to collect the electrical energy generated by the piezoelectric disks 253.

[0033] An energy storage system is arranged in the turnstile box body 10. The slip ring 255 and the power generation module 28 are respectively connected with the energy storage system. The energy storage system is used to store electrical energy. The slip ring is placed at the center of the disk to ensure seamless transmission of the charges generated by the piezoelectric disks to the energy storage system. This process will not interrupt the continuous rotation of the disk, thus realizing efficient energy collection and uninterrupted system operation.

[0034] The energy storage system includes a rectifier, which is used to convert the alternating current (AC) generated by the piezoelectric disks into direct current (DC). The direct current is suitable for storage in batteries and capacitors. For long-term energy storage, nickel-metal hydride batteries (NiMH) are widely favored due to their high energy density and are an ideal choice for powering devices such as lighting or sensors.

[0035] The energy storage system includes a power management integrated circuit. To optimize efficiency, the power management integrated circuit (PMIC) regulates the energy flow to ensure a reasonable distribution between storage and use, while preventing power loss or overcharging. Since the output voltage of the piezoelectric collector may fluctuate, a voltage regulator is crucial for stabilizing the output and maintaining a constant voltage for the connected devices. The energy storage system also includes an output circuit for distributing the stored energy to various devices, such as sensors, lighting, and communication networks in an urban environment.

[0036] On the inner sidewall of the impact cavity 251, guide posts 254 are symmetrically arranged. On the counterweight 252, guide grooves matching the guide posts 254 are provided. The guide posts 254 are located within the guide grooves, making the reciprocating sliding of the counterweight 252 smoother and ensuring that the impact force on the piezoelectric disk 253 remains consistent.

[0037] The piezoelectric disk 253 is in a disk shape and is made of a piezoelectric material. Specifically, the piezoelectric disk 253 is made of lead magnesium niobate-lead titanate (PMN-PT).

[0038] Lead magnesium niobate-lead titanate (PMN-PT) is selected as the material for the piezoelectric disk 253 due to its high piezoelectric coefficient (2000–2500 pC / N), durability, and efficiency. PMN-PT can generate a large amount of charge under mechanical stress, making it an ideal material for capturing the impact energy of pedestrians. Although alternative materials such as barium titanate (BaTiO3) and quartz (SiO2) are available, their piezoelectric coefficients are relatively low (BaTiO3 is typically between 100 and 190 pC / N), making them less suitable for high-output systems. Selecting PMN-PT ensures that a higher electrical output can be generated for each impact, thereby reducing the number of piezoelectric elements required to achieve the desired energy generation.

[0039] The counterweight 252 is made of lead because of its high density (11.3 g / cm 3 ), which can maximize the impact force applied to the piezoelectric disk 253.

[0040] The counterweight 252 is in a cylindrical shape. Rounded corners 2521 are provided at the edges of both end faces of the counterweight 252. The rounded corners 2521 are beneficial for reducing the friction during the sliding of the counterweight 252, thereby reducing energy loss and improving the energy conversion rate. The diameter of the counterweight 252 is 20 - 25 mm, and the height is 12 - 18 mm.

[0041] The outside of the counterweight 252 is wrapped with an isolation coating to prevent lead from being directly exposed to the environment, thereby ensuring that any potential lead pollution is controlled.

[0042] The isolation coating can be made of epoxy resin.

[0043] The energy conversion disk 25 is in a disk shape, and the impact cavity 251 is arranged along the diameter direction of the energy conversion disk 25.

[0044] The impact cavity 251 is made of a smooth and low-friction material. Specifically, it is made of Polysmooth material, a material similar to PLA. The inner side wall of the impact cavity 251 is smoothed with vaporized isopropyl alcohol, further reducing the proportion of energy lost due to friction.

[0045] The inner center of the rotating disk 21 and the center of the first gear 23 are respectively connected to drive rotating shafts. The two drive rotating shafts are connected and driven by bevel gears, so that the rotating disk 21 and the first gear 23 can be set at different angles, improving flexibility.

[0046] The gear ratio of the second gear 24 to the first gear 23 is 1:300. For every one rotation of the first gear 23, the second gear 24 will rotate 300 times, and then the energy conversion disk 25 will rotate 300 times, greatly increasing the number of times the counterweight 252 impacts the piezoelectric disk 253.

[0047] The third gear 26 is a bevel gear.

[0048] Compared with the prior art, although the energy output of the piezoelectric disk of the ticket gate system with an energy collection function of the present invention is limited compared with that of an electromagnetic generator, it still represents a significant progress in the field of hybrid energy collection. The electromagnetic system shows higher efficiency in capturing energy from rotational motion, while the piezoelectric element, although having a lower energy output, provides a complementary advantage by utilizing the energy of a single step. This dual mechanism can comprehensively improve the energy capture efficiency and system versatility, especially in an environment with a large flow of people.

[0049] The above are only the preferred embodiments of the present invention, and do not limit the patent scope of the present invention accordingly. Any modifications, equivalent substitutions, and improvements made within the concept of the present invention should be included in the patent protection scope of the present invention.
