During hiking, it can provide power for mobile phones, GPS and other devices without a power socket.

[0003] The existing portable power generation and charging equipment mainly includes two types: solar panel power generation and hand-cranked generator power generation. Among them, the power generation efficiency of solar panels is low, the energy storage speed is relatively slow, and it is greatly affected by weather and light intensity.

[0008] Furthermore, slip knots are installed at both ends of the planetary gearbox, and a locking pin for limiting the rotation of the planetary gearbox is installed on each slip knot.

[0009] Furthermore, the weight block is in the shape of a disk composed of at least three fan-shaped cloth bags, the number of cloth bags constituting the disk-shaped weight block is the same as the number of support rods, and a gap is left between two adjacent cloth bags for the support rods to pass through.

When the heavy object is hung on the support frame, the bottom of the support rod will be subjected to a large pressure. Since the end of the support rod that contacts the ground is placed at a certain angle to the ground, when the support rod is subjected to a large pressure from the heavy object, the support rod and the ground slide relative to each other, resulting in an unstable support structure. The strap can provide traction for the support rod, so that the support rod cannot slide relative to the ground, thereby preventing the support from being collapsed by the heavy object, so that this support structure can be smoothly used for lifting and lowering heavy objects. When storing energy, it is necessary Lift the heavy object to a high position, first start the integrated charging and power generation device, lift the heavy object to a high position, thereby completing the energy storage process. When the heavy object falls, the steel wire rope on the traction pulley mechanism of the heavy object block drives the integrated charging and power generation machine to rotate and generate electricity. At this time, the gravitational potential energy of the heavy object is converted into electrical energy, completing the power generation process. The generated electricity can be used to operate electrical appliances to meet people's needs. Compared with traditional technologies, this technical solution combines the support structure with gravity energy storage power generation, replacing traditional solar panel power generation and hand-cranked generator power generation.

[0021] Preferably, Figure 3 and Figure 4 As shown, the charging and power generation device 7 includes a generator 8, a torque handle 9, a planetary gearbox 10 and a reel 11. The reel 11 is a carbon fiber reel 11. One end of the planetary gearbox 10 is fixedly connected with the output shaft of the generator 8 and / or the torque handle 9 by screws. The generator 8 and the torque handle 9 can be installed at one end of the planetary gearbox 10 at the same time. The two can also be alternately connected to the end of the planetary gearbox 10 in a detachable manner. When the generator 8 is running, it represents the weight block 6 falling, the energy release process, the generator 8 generates electricity, and when the torque handle 9 is running, it represents the weight block 6 rising, the energy storage process, the weight block 6 is lifted to a high position by hand-cranking the torque handle 9, and the other end of the planetary gearbox 10 is fixedly connected with the reel 11 by coaxial screws. Preferably, the generator 8 is a permanent magnet generator, which contains a four-quadrant frequency converter. When the weight drops, the carbon fiber rope pulls the reel 11 to rotate, and the reel 11 drives the planetary gearbox 10. The planetary gearbox 10 increases the speed and transmits the power to the permanent magnet motor. The permanent magnet motor rotates at a rated speed and generates electricity under the control of the four-quadrant frequency converter. The four-quadrant inverter adopts IGBT technology closed-loop control algorithm, and continuously adjusts the control parameters of the IGBT according to the feedback signal to achieve a uniform descent of the weight block 6, with an energy feedback efficiency of nearly 97%.

[0022] Preferably, both ends of the planetary gearbox 10 are fixed with slip knots 12 by screws, and each slip knot 12 is installed with a locking pin for limiting the rotation of the planetary gearbox 10 .

[0023] Preferably, Figure 5 and Figure 6 As shown, the weight block 6 is a disk-shaped object composed of at least three fan-shaped cloth bags 13. The number of cloth bags 13 that make up the disk-shaped weight block 6 is the same as the number of support rods 1. A gap 14 is left between two adjacent cloth bags 13 for the support rods 1 to pass through. Preferably, each cloth bag 13 is provided with a loading port 15. Each cloth bag 13 is provided with a skeleton 16 for shaping. The skeleton 16 is located at the corners and / or edges of the cloth bag 13. The skeleton 16 can be set at the corners of the cloth bag 13 or at the edges of the cloth bag 13. Preferably, the skeleton 16 is set at the corners and edges of the cloth bag 13 at the same time. The skeleton 16 is made of carbon fiber material, and its function is to maintain the structural stability of the disk-shaped weight and prevent deformation. In order to reduce the weight of the equipment, the weight block 6 adopts a high-strength carbon fiber bag. When stored, only the very light cloth bag 13 is required to be assembled. When equipping, materials can be obtained nearby, and soil, sand, water, etc. can be loaded into the cloth bag 13 through the loading port 15. The loading port 15 is sealed with a screw cap, and the weight block 6 is set to a disc shape and has a unique appearance design composed of multiple independent fan-shaped cloth bags 13, which can increase the loading volume of the cloth bag 13, and at the same time, it also improves the center of gravity of the weight to a certain extent, and increases the work done by lifting the weight; all cloth bags 13 are nearly disc-shaped, and all cloth bags 13 are preferably divided into three petals, and can also be divided into four petals, five petals and six petals, etc. The specific number of petals of the cloth bag 13 is determined according to the number of support rods 1 on the bracket 2. Because as the weight is lifted, the space area surrounded by the tripod gradually decreases, in order to prevent the weight from being stuck, it is divided into petals. The design of the disc-shaped weight can improve the overall center of gravity of the weight and increase the work distance of the weight.

[0024] Preferably, Figure 2 As shown, a snap buckle 17 is provided between the strap 4 and the integrated charging and power generating device, the integrated charging and power generating device and the strap 4 are detachably connected via the snap buckle 17, the three drawstrings abc are connected at point f, the eg drawstring is respectively connected to the ab drawstrings, and the L thread on the eg drawstring is used to fix the integrated charging and power generating device 7.

[0025] Preferably, Figure 7 As shown, the pulley mechanism 5 is a pulley group consisting of a fixed pulley 18 and a movable pulley 19. The fixed pulley 18 is connected to the fixed head 3 by a hook, and the movable pulley 19 is connected to the weight block 6 by a hook. The movable pulley 19 is composed of 10 pulleys, which can reduce the weight of the weight block 6 to one tenth, and at the same time the stroke can be increased tenfold.

[0026] Preferably, the fixed pulley 18 and the movable pulley 19 are both wound with a traction rope 20, one end of the traction rope 20 is wound around the drum 11, and the traction rope 20 is made of carbon fiber material.

[0027] The working principle of the device is as follows: each support rod 1 on the bracket 2 has multiple telescopic sections, and the support rod 1 can be extended and retracted to adjust the height of the bracket 2. When the bracket 2 is unfolded, the bottom ends of the support rods 1 are spread apart from each other and tilted at an angle to the ground, and the top ends of the support rods 1 converge at the fixed head 3 and can rotate, so that the bracket 2 is easy to store and carry. The strap 4 at the bottom is fixed to the support rod 1 through a hook, so that the bracket 2 can maintain the overall structural stability when subjected to the gravity of the heavy block 6 to prevent it from being crushed by the heavy block 6. The snap buckle 17 can be adopted Using L-thread, the charging and power generation device 7 is fixed to the belt 4 through the snap buckle 17, which can be easily disassembled. The cloth bag 13 of the heavy block 6 is filled with local materials. The filling medium can be water, sand or soil, etc., and then the pulley mechanism 5 is connected with the hook at the fixed head 3 through the hook on the fixed pulley 18, and the hook at the movable pulley 19 is connected to the heavy object suspension. The gap 14 between each adjacent cloth bag 13 is aligned with the support rod 1 on the same side, so that the heavy block 6 will not be blocked by the support rod 1 when it is lifted or lowered, and the traction rope 20 on the pulley mechanism 5 is wound around the reel 11.

[0028] When generating electricity, energy is stored first and then released. Initially, the weight block 6 is located at a low position, the generator 8 is disconnected from the planetary gearbox 10, and the torque handle 9 is used to replace the generator 8 and connect to the planetary gearbox 10. By manually cranking the torque handle 9, the torque can be reduced by a dozen times using the torque principle. After that, the planetary gearbox 10 drives the reel 11 to rotate, and the traction rope 20 is wound on the reel 11. The weight block 6 is pulled and lifted to the high position of the bracket 2, and the locking pin on the slipknot 12 on the right side of the planetary gearbox 10 is engaged to complete the energy storage process. When releasing energy, the torque handle 9 at the connection of the slipknot 12 on the left side of the planetary gearbox 10 is removed, and then the generator 8 is installed on this slipknot 12, the generator 8 is started, and the locking pin on the right slipknot 12 is loosened. The weight block 6 falls at a uniform speed, and the generator 8 generates electricity to complete the energy release process.

[0029] The portable mechanical potential energy power generation and charging device of the present invention has a support rod 1 and a bracket 2 which can provide a height space for the lifting of a weight block 6. When the weight block 6 is suspended on the bracket 2, the bottom of the support rod 1 will be subjected to a large pressure. Since the end of the support rod 1 in contact with the ground is tilted at a certain angle to the ground, when the support rod 1 is subjected to a large pressure from the weight block 6, the support rod 1 and the ground slide relative to each other, resulting in an unstable structure of the bracket 2. The strap 4 can provide traction for the support rod 1 to prevent the bracket 2 from being collapsed by the weight, so that the bracket 2 structure can be smoothly used for lifting and lowering the weight block 6. When storing energy, the weight block 6 needs to be lifted. 6 is lifted to a high position, first the charging and power generation integrated device 7 is started to lift the weight to a high position, thereby completing the energy storage process. When the weight block 6 falls, the steel wire rope on the traction pulley mechanism 5 of the weight block 6 drives the charging and power generation integrated machine to rotate and generate electricity. At this time, the gravitational potential energy of the weight block 6 is converted into electrical energy, completing the power generation process. The generated electricity can be used for electrical appliances to meet people's needs. Compared with traditional technology, this technical solution combines the bracket 2 structure with gravity energy storage power generation, replacing traditional solar panel power generation and hand-cranked generator 8 power generation, while ensuring portability, it also improves power generation efficiency, power generation durability and power generation stability.
