Description

Technical Field

[0001] This invention relates to the field of power generation equipment technology, specifically to an underground trampling and compaction power generation device. Background Technology

[0002] Human demand for and dependence on energy is increasing, leading to dwindling energy resources. Furthermore, the use of non-renewable energy sources causes severe environmental pollution, necessitating the development of various forms of renewable energy alternatives. Wind, solar, and hydropower, due to their abundant reserves and clean, pollution-free characteristics, have become ideal renewable energy sources. However, each of these power generation methods has its drawbacks; some pollute the environment, some consume large amounts of natural resources, and others are constrained by natural conditions and geographical environment. In reality, many green energy sources are available in daily life. For example, with the rapid development of national infrastructure, there is significant potential for tapping into the energy resources of transportation tools such as highways. Specifically, the rolling pressure generated by the contact between vehicle wheels and the road surface during driving is immense, with numerous highways carrying huge daily traffic volumes, generating a continuous flow of rolling pressure.

[0003] Chinese Patent Publication No. CN 105003399 B discloses a power generation system that utilizes the rolling pressure of vehicle wheels on a road surface to generate electricity. The system includes a load-bearing mechanism, a hydraulic mechanism, an energy conversion mechanism, an energy accumulation and release mechanism, a machine room located below the road surface, and a work area located on the roadside. When a vehicle passes over the load-bearing mechanism, rolling pressure is generated. The load-bearing mechanism stores this rolling pressure as high-pressure hydraulic energy through the hydraulic mechanism. The energy conversion mechanism then converts this high-pressure hydraulic energy into mechanical energy and outputs it to the energy accumulation and release mechanism.

[0004] The power generation system in the aforementioned patent converts mechanical energy into hydraulic energy, and then converts hydraulic energy back into mechanical energy to generate electricity. However, this power generation method consumes a lot of energy in the middle and stores less power. Moreover, the energy collection in this patent comes only from the downward pressure, and the energy cannot be collected and utilized when the load-bearing mechanism is reset, resulting in low power generation efficiency.

[0014] As a further technical solution of the present invention, the two ends of the power storage shaft are provided with a first one-way gear and a second one-way gear respectively meshing with two drive racks; the first one-way gear and the second one-way gear adopt the same structure, and the driving directions of the first one-way gear and the second one-way gear are opposite.

[0015] As a further technical solution of the present invention, the second one-way gear includes a gear outer ring, the inner side of which is slotted, and a locking tooth is movably connected in the slot via a rotating shaft; a plurality of locking teeth are provided, and a stop block is provided on the outer side of each locking tooth; an inner gear ring is also provided on the inner side of the gear outer ring to engage with the plurality of locking teeth.

[0016] As a further technical solution of the present invention, the outer ring of the gear is evenly distributed with a plurality of tooth housings, each tooth housing is movably connected to a tooth through a rotating shaft, and a torsion spring is sleeved between the tooth and the rotating shaft.

[0017] As a further technical solution of the present invention, a power storage auxiliary component is provided on one side of the power storage mechanism to engage with the prying teeth. The power storage auxiliary component includes two slide rods, the two ends of which are respectively fixedly connected to a fixed block and a connecting plate, and a stop block is slidably connected on the slide rods; a return spring is provided below the stop block and is sleeved on the slide rod; a pressure sensor is also provided between the return spring and the fixed block; an electromagnet is fixed on the fixed block and is located between the two slide rods; the electromagnet is electrically connected to the battery.

[0019] As a further technical solution of the present invention, both drive plates are slidably connected to the slide; two slides are provided; the two slides are respectively fixedly connected to the first fixed bracket and the second fixed bracket.

[0020] A method for using an underground trampling and compaction power generation device includes the following steps:

[0021] Step 1: Installation of the power generation device. First, dig a well in an area with high pedestrian and vehicle traffic. Level the well and attach insulation boards to the inside of the well wall. Lay insulation bricks inside the insulation boards and harden the inside of the insulation bricks with cement mortar. After the cement mortar has cured and dried, place the equipment into the well, so that the lower pressure plate is above or level with the ground.

[0022] Step 2: Circuit setup. Install a controller inside the equipment and electrically connect the pressure sensor and electromagnet to the controller; the electromagnet and controller are also electrically connected to the battery.

[0023] Step 3: Driving the device. When a vehicle or crowd walks on the lower pressure plate, the downward pressure from gravity compresses the spring, causing it to move downwards and flip the two drive plates inwards. With the cooperation of the two fisheye joints, the drive rack moves downwards. When charging the power spring, there are two charging methods. The first method is that the first and second one-way gears drive in the same direction, and the two drive racks are set on the same side. In this configuration, when the drive rack moves downwards, the first and second one-way gears rotate in the same direction, simultaneously driving the power storage shaft to rotate, thereby achieving the charging of the power spring.

[0024] The second driving method involves setting the first and second one-way gears in opposite directions and placing them on opposite sides of the drive racks. During driving, one drive rack rotates the second one-way gear, while the other drive rack rotates the first one-way gear. However, the first one-way gear does no work on the power storage shaft; only the second one-way gear rotates the power storage shaft. As the power storage shaft rotates, the power storage spring begins to contract inward and store power. The rotating housing, which follows the rotation of the power storage shaft, drives the shifting teeth and their housing to rotate. After rotating one position, the shifting teeth are engaged on the stop block. During the return stroke of the drive rack, the first one-way gear rotates the power storage shaft to store power, thus ensuring that the power storage spring stores power during both bidirectional movement of the drive rack. This improves the effective utilization of the force generated by the movement of the drive rack and increases the power storage efficiency of the power storage spring.

[0025] Step Four: Release of the accumulator spring and power generation. While the accumulator mechanism is accumulating power, the gears engage with the stop block. The stop block compresses the return spring, which in turn releases a certain amount of elasticity to the pressure sensor. When the pressure sensor reaches the set value, the electromagnet is energized, quickly closes, and attracts the stop block. At this point, the accumulator spring, no longer obstructed by the stop block, rapidly releases, driving the accumulator shaft to rotate. The first gear, through the cooperation of the second and third gears, drives the generator to start generating electricity. The sizes of the first, second, and third gears decrease sequentially, thereby increasing the speed and the number of rotations, thus improving the generator's power generation efficiency. When the pressure reading of the pressure sensor is zero or close to zero, the controller controls the electromagnet to release, ensuring that the accumulator spring is not disturbed when releasing rotational force, thus guaranteeing the power generation effect.

[0026] Beneficial effects:

[0027] In this invention, when a vehicle or a group of people walks on the lower pressure plate, they are pressed down by gravity, compressing the spring downwards and causing the two drive plates to flip inwards. With the cooperation of the two fisheye joints, the drive rack moves downwards, causing the drive rack to move downwards. When charging the power spring, there are two charging methods. The first method is that the first one-way gear and the second one-way gear have the same one-way driving direction, and the two drive racks are set on the same side. With this setting, when the drive rack moves downwards, the first one-way gear and the second one-way gear rotate in the same direction, driving the power storage shaft to rotate, thereby achieving the charging of the power spring.

[0028] In this invention, the second driving method involves setting the first and second one-way gears in opposite directions and placing the two drive racks on opposite sides. During driving, one drive rack rotates the second one-way gear, while the other drive rack rotates the first one-way gear. However, the first one-way gear does no work on the power storage shaft; only the second one-way gear rotates the power storage shaft. As the power storage shaft rotates, the power storage spring begins to contract inward and store power. The rotating housing, which follows the rotation of the power storage shaft, drives the shifting teeth and their housing to rotate. After rotating one position, the shifting teeth are engaged on the stop block. During the return stroke of the drive rack, the first one-way gear rotates the power storage shaft to store power, thus ensuring that the power storage spring stores power during bidirectional movement of the drive rack. This improves the effective utilization of the force generated by the movement of the drive rack and increases the power storage efficiency of the power storage spring.

[0029] In this invention, while the energy storage mechanism is storing energy, the gears engage with the stop block. The stop block compresses the return spring, which in turn releases a certain amount of elastic force onto the pressure sensor. When the pressure sensor reaches a set value, the electromagnet is energized, quickly closes, and attracts the stop block. At this time, the energy storage spring, no longer obstructed by the stop block, rapidly releases, driving the energy storage shaft to rotate. The first gear, through the cooperation of the second and third gears, drives the generator to start generating electricity. The dimensions of the first, second, and third gears decrease sequentially, thereby increasing the speed and the number of rotations, thus improving the generator's power generation efficiency. When the pressure index of the pressure sensor is zero or close to zero, the controller controls the electromagnet to release, ensuring that the energy storage spring is not disturbed when releasing rotational force, thus guaranteeing the power generation effect.

[0049] In this embodiment, the two drive plates 4 are arranged in a figure-eight shape, and the outer ends of the two drive plates 4 are fixed to the inner wall of the outer shell 5 through a movable connecting seat; a movable connecting seat is provided at the middle position of the bottom of the drive plate 4 and is movably connected to the drive rod 6.

[0050] In this embodiment, the fixed housing 93 is rotatably connected to the power storage shaft 91 via a bearing, and a second fixed bracket 21 is welded to the outside of the fixed housing 93; the fixed housing 93 is slidably connected to the inside of the rotating housing 94 via a slip ring 95; the rotating housing 94 is interference-fitted with the power storage shaft 91; a first fixed bracket 20 is provided on the outside of the rotating housing 94; the first fixed bracket 20 is rotatably connected to the power storage shaft 91 via a bearing.

[0052] As another driving method in this embodiment, the first one-way gear 98 and the second one-way gear 99 are set in opposite directions for one-way driving, and the two driving racks 8 are set on different sides.

[0053] In this embodiment, the second one-way gear 99 includes a gear outer ring 991, the inner side of which is slotted, and a retaining tooth 992 is movably connected in the slot via a rotating shaft; a plurality of retaining teeth 992 are provided, and a stop is provided on the outer side of each retaining tooth 992; an inner gear ring 993 is also provided on the inner side of the gear outer ring 991 to engage with the plurality of retaining teeth 992.

[0057] In this embodiment, both drive plates 4 are slidably connected to the slide 22; two slides 22 are provided; the two slides 22 are respectively fixedly connected to the first fixed bracket 20 and the second fixed bracket 21.

[0058] A method for using an underground trampling and compaction power generation device includes the following steps:

[0059] Step 1: Installation of the power generation device. First, dig a well in an area with high pedestrian and vehicle traffic. Level the well and attach insulation boards to the inside of the well wall. Lay insulation bricks inside the insulation boards and harden the inside of the insulation bricks with cement mortar. After the cement mortar has cured and dried, place the equipment into the well, so that the lower pressure plate 1 is higher than or level with the ground.

[0060] Step 2: Circuit setup. Install a controller inside the equipment and electrically connect the pressure sensor and electromagnet to the controller; the electromagnet and controller are also electrically connected to the battery.

[0061] Step 3: Driving the device. When a vehicle or crowd walks on the lower pressure plate 1, it is pressed down by gravity, compressing the spring 2 downward and causing the two drive plates 4 to flip inward. With the cooperation of the two fisheye joints 7, the drive rack 8 is driven to move downward. When the power-saving spring 92 is charged, there are two charging methods. The first method is that the first one-way gear 98 and the second one-way gear 99 have the same one-way driving direction, and the two drive racks 8 are set on the same side. In this way, when the drive rack 8 moves downward, the first one-way gear 98 and the second one-way gear 99 rotate in the same direction, and at the same time drive the power-saving shaft 91 to rotate, thereby achieving the charging of the power-saving spring 92.

[0062] The second driving method involves setting the first one-way gear 98 and the second one-way gear 99 in opposite directions, and placing the two drive racks 8 on opposite sides. During driving, one drive rack 8 drives the second one-way gear 99 to rotate, while the other drive rack 8 drives the first one-way gear 98 to rotate. However, the first one-way gear 98 does no work on the power storage shaft 91; only the second one-way gear 99 drives the power storage shaft 91 to rotate. Under the rotation of the power storage shaft 91, the power storage spring 92 begins to contract inward and store power. The rotating housing 94, which follows the rotation of the power storage shaft 91, drives the shifting tooth 96 and the shifting tooth housing 97 to rotate. After rotating one position, the shifting tooth 96 is engaged in the stop block 112. When the drive rack 8 returns, the first one-way gear 98 rotates and stores power on the power storage shaft 91, thus ensuring that the power storage spring 92 can store power when the drive rack 8 moves in both directions. This improves the effective utilization of the force generated by the movement of the drive rack 8 and increases the power storage efficiency of the power storage spring 92.

[0063] Step 4: Release of the accumulator spring and power generation. While the accumulator mechanism 9 is accumulating power, the gear 96 engages with the stop block 112. The stop block 112 compresses the return spring 113, which in turn releases a certain amount of elastic force to the pressure sensor 116. When the pressure sensor 116 reaches the set value, the electromagnet 115 is energized, quickly closes, and attracts the stop block 112. At this time, the accumulator spring 92, no longer blocked by the stop block 112, is quickly released, driving the accumulator shaft 91 to rotate. The first gear 14, through the cooperation of the second gear 15 and the third gear 17, drives the generator 18 to start generating electricity. The sizes of the first gear 14, the second gear 15, and the third gear 17 decrease sequentially, thereby achieving a speed increase and increasing the number of rotations, thus improving the power generation efficiency of the generator 18. When the pressure index of the pressure sensor 116 is zero or close to zero, the controller controls the electromagnet 115 to release, thus ensuring that the accumulator spring 92 is not disturbed when releasing rotational force, ensuring the power generation effect.

In this way, when the drive rack (8) moves downward, the first one-way gear (98) and the second one-way gear (99) rotate in the same direction, and at the same time drive the power-saving shaft (91) to rotate, thereby achieving the power-saving spring (92). The second driving method: The first one-way gear (98) and the second one-way gear (99) are set in opposite directions, and the two driving racks (8) are set on different sides; during driving, one of the driving racks (8) drives the second one-way gear (99) to rotate, while the other driving rack (8) drives the first one-way gear (98) to rotate, but the first one-way gear (98) does no work on the power storage shaft (91), only the second one-way gear (99) drives the power storage shaft (91) to rotate, and the power storage spring (92) is activated by the rotation of the power storage shaft (91). It begins to contract inward and store power; the rotating outer shell (94) that follows the rotation of the power storage shaft (91) drives the paddle (96) and the paddle shell (97) to rotate. After the paddle (96) rotates one station, it is stuck on the stop block (112); when the drive rack (8) returns, the first one-way gear (98) rotates the power storage shaft (91) to store power, thereby ensuring that the power storage spring (92) can be stored when the drive rack (8) moves in both directions, improving the effective use of the force brought by the movement of the drive rack (8) and improving the power storage efficiency of the power storage spring (92); Step 4: Release and power generation of the accumulator spring. While the accumulator mechanism (9) is accumulating power, the pawl (96) will engage with the stop block (112). The stop block (112) compresses the return spring (113), and the return spring (113) releases a certain elastic force to the pressure sensor (116). When the pressure sensor (116) reaches the set value, the electromagnet (115) is energized, closes quickly, and attracts the stop block (112). At this time, the accumulator spring (92), which is no longer blocked by the stop block (112), is quickly released, driving the accumulator shaft (91) to rotate. The first tooth... The wheel (14) drives the generator (18) to generate electricity through the cooperation of the second gear (15) and the third gear (17). The size of the first gear (14), the second gear (15) and the third gear (17) decreases in sequence, thereby achieving the purpose of increasing speed and increasing the number of rotations, thus improving the power generation efficiency of the generator (18). When the pressure index of the pressure sensor (116) is zero or close to zero pressure, the controller controls the electromagnet (115) to release, thereby ensuring that the power-saving spring (92) is not disturbed when releasing the rotational force, and ensuring the power generation effect.
