Description

Technical Field

[0001] The present invention relates to the technical field of mining equipment, and in particular to a device and method for generating electricity by utilizing kinetic energy recovery. Background Art

[0002] In the process of mining mineral resources, a large amount of ore needs to be transported from a high-altitude mining site to a low-lying processing area. Since the ore located at a higher position carries gravitational potential energy, in order to recover this part of the energy, some people have designed relevant energy recovery devices. This energy recovery device can convert the gravitational potential energy of the ore into other energy that can be easily stored and transported, such as electrical energy. In an existing energy recovery device, the device includes a body, a supporting plate for receiving the ore mounted on the body by a spring device, and a generator connected to the supporting plate by a transmission structure. When in use, the ore falls from the mountain and lands on the supporting plate. During the ore falling process, the gravitational potential energy of the ore is converted into kinetic energy. The spring device can convert the kinetic energy acting on the supporting plate into elastic potential energy. The supporting plate bounces back and forth under the action of the elastic force. The reciprocating supporting plate drives the generator to rotate and generate electricity through the transmission structure, and finally converts the gravitational potential energy of the ore into electrical energy that is easy to store and transport. In actual use, the aforementioned energy recovery device requires securing the ore to a support plate in order to fully recover the kinetic energy of the ore as it falls. Currently, although a small number of energy recovery devices are equipped with corresponding securing means, these securing means only secure the ore and lack the ability to crush it, hindering subsequent transportation of the ore. To address this issue, the present invention proposes a device and method for generating electricity using kinetic energy recovery. Summary of the Invention

[0009] Optionally, the discharge structure further includes a fence, which is arranged around the bottom plate, and the side of the fence facing the discharge port is an open structure, and the oil cylinder or the air cylinder is connected between the fence and the bottom plate.

[0010] Optionally, there is an installation gap between the installation portion and the inner wall of the body, an inclined portion for shielding the installation gap is formed on the top of the installation portion, and the spring device is arranged in the installation gap.

[0011] Optionally, the spring device includes an upper limit plate, a lower limit plate, a positioning shaft connected between the upper and lower limit plates, and an upper compression spring and a lower compression spring sleeved on the outside of the positioning shaft. The upper and lower limit plates are fixed on the inner wall of the machine body at intervals, and the supporting plate slides on the positioning shaft. The upper compression spring and the lower compression spring are respectively located at the upper and lower parts of the supporting plate.

[0012] Optionally, the motion conversion structure is a crank slider mechanism.

[0013] According to another aspect of the present invention, there is provided a method for recovering kinetic energy of ore using the above-mentioned device for power generation by kinetic energy recovery, comprising the following steps: S100, installing the body of the device for generating electricity by utilizing kinetic energy recovery at the foot of a mine, with the opening of the body aligned with the ore mining location; S200, ore falls from the mining location, and the gravitational potential energy of the ore is converted into kinetic energy.

[0014] Compared with the prior art, the present invention provides a device and method for generating electricity by recycling kinetic energy, which has the following beneficial effects: 1. The present invention achieves a purely mechanical effect of automatically securing the ore to the load plate through the interaction of the mounting portion, the stopper, and the first elastic element, preventing the ore from being ejected from the machine body by the spring device and fully recovering the ore's kinetic energy. Furthermore, through the interaction of the extrusion member, the stopper, the drive gear, and the rack, the kinetic energy of the ore is utilized to crush the ore, facilitating subsequent transportation of the ore. 2. The present invention can effectively reduce the cost and difficulty of removing ore from the machine body by providing a discharge structure used in conjunction with a fixed crushing structure; When the ore is removed from the machine body, the bottom plate is driven to flip downward, the drop opening is gradually opened, and the convex part on the oil cylinder or the cylinder will also rotate in the direction away from the crushing teeth. The tip of the crushing tooth is retracted into the installation groove under the rebound force of the second elastic member, and the ore on the bottom plate will not be blocked by the tip of the crushing tooth and can slide smoothly out of the drop opening to the outside of the machine body. 4. The discharge structure of the present invention also includes a fence, which not only provides a basis for the installation of the oil cylinder or the air cylinder, but also forms a discharge channel with the bottom plate when the discharge port is opened. When the ore slides out along this discharge channel, it is not easy to fall into the bottom of the machine body, ensuring that all the ore can be discharged. BRIEF DESCRIPTION OF THE DRAWINGS

[0017] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments 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.

[0018] Example: See Figures 1 to 8According to one aspect of an embodiment of the present invention, there is provided a device for generating electricity by recycling kinetic energy, which includes a body 100, a supporting plate 200, and a generator 300. In order to facilitate the integration of components such as the body 100 and the generator 300, the device also includes a substrate 400. Components such as the body 100 and the generator 300 are all mounted on the substrate 400, and these components can be moved together during transportation. In order to facilitate movement, casters can also be installed at the bottom of the substrate 400. When the device has the above-mentioned substrate 400, it will be more suitable for situations where the use occasion needs to be frequently changed. Of course, in some embodiments, the substrate 400 is not necessary, and components such as the body 100 and the engine can also be installed on the ground, such as a concrete floor. When the device does not have the above-mentioned substrate 400, it will be more suitable for situations where the use occasion does not change easily. The body 100 is a hollow container with an open top. In this example, the body 100 is square in shape, but it can also have other geometric shapes, such as cylindrical or elliptical. The support plate 200 is elastically mounted within the body 100 via a spring mechanism. The support plate 200 is provided with a fixed crushing structure for securing and crushing ore 900 that falls onto the support plate 200. The rotor of the generator 300 is connected to the support plate 200 via a motion conversion structure, so that the motion conversion structure converts the linear motion of the support plate 200 into rotational motion of the rotor of the generator 300. The fixed crushing structure includes a mounting portion 610, a stopper 620 and an extrusion member 630. At least two mounting portions 610 are fixedly arranged on the bearing surface of the bearing plate 200 at intervals. The bearing surface is the side of the bearing plate 200 that receives the impact of the ore 900, and the bearing surface faces the upper end opening of the body 100; at least one mounting portion 610 is elastically provided with a stopper 620 through a first elastic member 640. The first elastic member 640 can provide a rebound force for the stopper 620 to flip toward the upper end opening of the body 100. Specifically in this example, a telescopic rod 641 is connected between the mounting portion 610 and the stopper 620. The first elastic member 640 is connected to the mounting portion 610 and the stopper 620. 0 represents a first coil spring sleeved around the exterior of the telescopic rod 641. The telescopic rod 641 is composed of two rods of different diameters that are movably connected together. Each rod has a protruding stopper 642. The ends of the telescopic rod 641 are rotatably connected to the stopper 620 and the mounting portion 610 via a rotating shaft. The first coil spring sleeves around the exterior of the telescopic rod 641, and the ends of the first coil spring abut against the stoppers 642 on the two rods of different diameters. This arrangement ensures that the first coil spring is subjected primarily to axial forces and virtually no radial forces during compression, thereby extending the service life of the first elastic member 640. Of course, the specific structure of the first elastic member 640 is not particularly limited in this application, as long as it can provide a rebound force that causes the stopper 620 to tilt toward the upper opening of the housing 100. One end of the stopper 620 is rotatably connected to the mounting portion 610, and at least a portion of the stopper 620 is provided with a drive gear 621. Specifically, the stopper 620 can be rotatably connected to the mounting portion 610 via a rotating shaft, hinge, or other structure. It will be appreciated that the number of mounting portions 610 and the number of stoppers 620 on each mounting portion 610 can be set as needed. In one embodiment, there are two mounting portions 610, which are spaced apart and face each other, and the ore 900 will fall into the gap between the two mounting portions 610. In another embodiment, there are more than two mounting portions 610, and the more than two mounting portions 610 form a space on the supporting surface of the supporting plate 200, and the ore 900 can fall into the space enclosed by these mounting portions 610.In one embodiment, only one mounting portion 610 is provided with a stopper 620. When the ore 900 falls onto the carrying plate 200, one side of the ore 900 will be pressed against the free end of the stopper 620 on the mounting portion 610 provided with the stopper 620 under the elastic force of the first elastic member 640, and the other side of the ore 900 will be pressed against another mounting portion 610 opposite to the mounting portion 610 provided with the stopper 620. In another embodiment, more than one mounting portion 610 is provided with a stopper 620. When the ore 900 falls, After being placed on the support plate 200, the ore 900 is clamped between the free ends of the multiple stoppers 620 on the mounting portion 610 under the elastic force of the first elastic member 640. The extrusion member 630 is slidably connected to the mounting portion 610. The extrusion member 630 has a rack 631 that meshes with the drive gear 621 of the stopper 620. Specifically, in this embodiment, the extrusion member 630 is provided with two parallel polished rods 632, which are movably connected to the mounting portion 610. The extrusion member 630 is slidably connected to the mounting portion 610 via the polished rods 632. In other embodiments, the extrusion member 630 can also be slidably connected to the mounting portion 610 via a slider and rail structure.

[0019] A device for generating electricity by utilizing kinetic energy recovery using the above-mentioned structure is installed at the foot of a mine, with the opening of the body 100 aligned with the mining position of the ore 900. The ore 900 falls from the mining position, and the gravitational potential energy of the ore 900 is converted into kinetic energy. The fallen ore 900 will eventually fall into the body 100 from the opening of the body 100. Of course, in order to ensure that the ore 900 can smoothly enter the body 100, a guide structure (not shown) can be arranged on the path where the ore 900 falls. The guide structure is used to accurately guide the fallen ore 900 into the body 100. After the ore 900 falls into the body 100, it will be caught by the supporting plate 200. The supporting plate 200 reciprocates up and down under the action of the spring device. The supporting plate 200 drives the generator 300 to rotate and generate electricity through the motion conversion structure, thereby realizing the recovery of the kinetic energy of the ore 900. During the up and down reciprocating motion of the supporting plate 200, the fixed crushing structure on the supporting plate 200 will automatically fix the ore 900 on the supporting plate 200 and crush it at the same time. This not only prevents the ore 900 from being ejected from the body 100 and fully recovers the kinetic energy of the ore 900, but also can perform preliminary crushing of the ore 900, facilitating the subsequent transportation of the ore 900. The specific working method of the fixed crushing structure is as follows: after the ore 900 enters the body 100, it will push the stopper 620 to flip downward. The stopper 620 is always in contact with the ore 900 under the elastic force of the first elastic member 640. On the one hand, when the ore 900 that falls on the supporting plate 200 has a tendency to leave the supporting plate 200 upward, the stopper 620 will clamp the ore 900 under the elastic force of the first elastic member 640 and limit the upward movement of the ore 900, thereby limiting the ore 900 on the supporting plate 200 to prevent the ore 900 from being ejected from the body 100; on the other hand, when the ore 900 pushes the stopper 620 to flip downward, the stopper 620 will also drive the extrusion member 630 to move toward the ore 900 under the transmission cooperation of the drive gear 621 and the rack 631, thereby finally achieving the effect of extruding and crushing the ore 900. In other words, the device not only achieves the purely mechanical effect of automatically securing the ore 900 to the carrier plate 200 through the interaction of the mounting portion 610, the stopper 620, and the first elastic element, thereby preventing the ore 900 from being ejected from the body 100 by the spring device and fully recovering the kinetic energy of the ore 900, but also utilizes the kinetic energy of the ore 900 to crush it through the interaction of the extrusion member 630, the stopper 620, the drive gear 621, and the rack 631, thereby facilitating subsequent transportation of the ore 900.

[0020] In the above embodiment, due to the setting of the fixed crushing structure, after the kinetic energy of the ore 900 is fully recovered, if the ore 900 needs to be removed from the machine body 100, a more easily conceivable method of removing the material is: using external force to drive the stopper 620 to flip in a direction close to the supporting plate 200, so that the stopper 620 no longer contacts the ore 900, so that the ore 900 can be removed from the upper end opening of the machine body 100. Although the above approach is feasible, it still has at least the following disadvantages: first, it may be necessary to set up an additional driving device to drive the stopper 620 to flip, resulting in an increase in the manufacturing cost of the device; second, since the ore 900 will be crushed by the extrusion member 630, some of the broken ore 900 may also become resistance when the stopper 620 flips toward the direction close to the supporting plate 200, making it difficult or impossible for the free end of the stopper 620 to separate from the ore 900; third, even if the free end of the stopper 620 can be successfully separated from the ore 900, removing the ore 900 from the upper opening of the body 100 requires overcoming the gravity of the ore 900, which in turn requires a lot of manpower and time costs. Based on this, in some embodiments, the device for generating electricity by recovering kinetic energy also includes a discharge structure that can facilitate the removal of the ore 900 in the body 100. The discharge structure includes a discharge port 800, a discharge port 810 and a bottom plate 820. The discharge port 800 is set on the supporting surface between the two mounting parts 610. The discharge port 810 is set on the side wall of the body 100. The bottom plate 820 is installed below the discharge port 800. One end of the bottom plate 820 is rotatably connected to the supporting plate 200, and the other end extends from the discharge port 810. With the above-described discharge structure, the discharge port 800 can be opened and closed by rotating the bottom plate 820. When the discharge port 800 is closed, the surface of the bottom plate 820 facing the discharge port 800 functions similarly to the bearing surface of the bearing plate 200, catching the ore 900 and converting its kinetic energy into elastic potential energy of the spring device. When the ore 900 needs to be removed from the machine body 100, the bottom plate 820 is rotated downward to open the discharge port 800. The ore 900 slides downward along the surface of the bottom plate 820 and is ultimately discharged through the discharge port 810 of the machine body 100 to the outside of the machine body 100. Compared to the above-described easy-to-think-of material removal method, using the discharge structure to remove the ore 900 from the machine body 100 can effectively reduce the cost and difficulty of removing the ore 900 from the machine body 100.

[0021] In some embodiments, the discharge structure further includes an oil cylinder or air cylinder 830 for driving the bottom plate 820 to flip. The oil cylinder or air cylinder 830 has a protrusion 831 on one end that is rotatably connected to the bottom plate 820. A mounting slot is provided through the bottom plate 820, and a crushing tooth 840 corresponding to the position of the protrusion 831 is elastically connected to the mounting slot via a second elastic member 850. Specifically, in this embodiment, the output shaft of the oil cylinder or air cylinder 830 has a cylindrical end that is rotatably connected to the bottom plate 820 via a rotating shaft or hinge. The protrusion 831 is triangular in structure and protrudes from the side of the cylindrical end. The second elastic member 850 is a second coil spring. The crushing tooth 840 has a force-bearing end that can abut against the protrusion 831 and a crushing end that faces the discharge port 800. The crushing end has a pointed structure. It can be understood that, by adopting the above-mentioned arrangement, the tip of the crushing tooth 840 can retract into the mounting slot or extend out of the mounting slot as the drop opening 800 is opened and closed, thereby further crushing the ore 900 while facilitating the ore 900 to slide out of the machine body 100 along the bottom plate 820. Specifically, when the drop opening 800 is closed by using the bottom plate 820, the protrusion 831 on the oil cylinder or the air cylinder 830 will resist the force-bearing end of the crushing tooth 840 and push the crushing tooth 840 toward the drop opening 800. The tip of the crushing tooth 840 will extend from the mounting slot into the drop opening 800. In this way, when the ore 900 falls on the bottom plate 820, the crushing tooth 840 can further crush the ore 900. Of course, in order to better crush the ore 900, the movement directions of the crushing teeth 840 and the extrusion piece 630 are perpendicular, so that the ore 900 can be crushed from multiple angles; and when it is necessary to take out the ore 900 in the body 100, the oil cylinder or the air cylinder 830 is used to drive the bottom plate 820 to flip downward, and the dropout port 800 is gradually opened. The protrusion 831 on the oil cylinder or the air cylinder 830 will also rotate in the direction away from the crushing teeth 840. The tip of the crushing tooth 840 retracts into the installation groove under the rebound force of the second elastic member 850, and the ore 900 on the bottom plate 820 will not be blocked by the tip of the crushing tooth 840 and can slide smoothly out of the dropout port 800 to the outside of the body 100.

[0022] In some embodiments, a rolling element 841 is provided on one side of the crushing tooth 840 adjacent to the protrusion 831. The crushing tooth 840 is in rolling contact with the protrusion 831 via the rolling element 841. The rolling element 841 may be a roller or a ball. The provision of the rolling element 841 can reduce contact friction between the crushing tooth 840 and the protrusion 831, thereby reducing component wear.

[0023] In some embodiments, there are multiple crushing teeth 840, and the multiple crushing teeth 840 are arranged in a straight line and fixed to a mounting plate 842. The mounting slot includes a movable slot 821 that accommodates the mounting plate 842 and a plurality of sockets 822 that accommodate the multiple crushing teeth 840. Specifically, in this embodiment, a second coil spring is sheathed on the exterior of each crushing tooth 840, with the two ends of the second coil spring respectively abutting against the top of the movable slot 821 and the mounting plate 842. It will be understood that by arranging the multiple crushing teeth 840 in a straight line, the tips of the multiple crushing teeth 840 can generate uniform force points on the bottom of the ore 900 in a straight line, thereby crushing the ore 900 into a more regular shape, facilitating the subsequent transportation of the ore 900.

[0024] In some embodiments, the discharge structure further includes a barrier 860, which surrounds the bottom plate 820. The side of the barrier 860 facing the discharge port 810 is open, and the oil or air cylinder 830 is connected between the barrier 860 and the bottom plate 820. This arrangement not only provides a foundation for the installation of the oil or air cylinder 830, but also forms a discharge channel with the bottom plate 820 when the discharge port 800 is opened. When the ore 900 slides out along this discharge channel, it is unlikely to fall into the bottom of the machine body 100, ensuring that the ore 900 can be completely discharged.

[0025] In some embodiments, a mounting gap 110 is defined between the mounting portion 610 and the inner wall of the housing 100. A sloped portion 611 is formed on the top of the mounting portion 610 to block the mounting gap 110, and the spring device is disposed within the mounting gap 110. This configuration provides space for the spring device, and the sloped portion 611 prevents ore 900 from falling into the mounting gap 110. Furthermore, the sloped portion 611 increases the upper opening of the space enclosed by the two mounting portions 610, making it easier for ore 900 to fall into the space enclosed by the two mounting portions 610.

[0026] In some embodiments, the spring device includes an upper limit plate 510, a lower limit plate 520, a positioning shaft 530 connected between the upper and lower limit plates 520, and an upper compression spring 540 and a lower compression spring 550 disposed on the exterior of the positioning shaft 530. The upper and lower limit plates 520 are fixed to the inner wall of the housing 100 at intervals. The support plate 200 slides over the positioning shaft 530. The upper compression spring 540 and the lower compression spring 550 are located at the upper and lower portions of the support plate 200, respectively. After the ore 900 falls onto the support plate 200, the ore 900 transfers kinetic energy to the upper and lower compression springs 550, causing the support plate 200 to slide back and forth along the positioning shaft 530 under the elastic force of the upper and lower compression springs 550. Of course, as long as the spring device can reciprocate up and down along the interior of the housing 100 after being impacted by the ore 900, the present application does not particularly limit the specific structure of the spring device.

[0027] In some embodiments, the motion conversion structure is a slider-crank mechanism. Specifically, in this embodiment, the slider-crank mechanism includes a drive wheel 710, a connecting rod 720, and a connecting rod 730. The connecting rod 730 is disposed on the exterior of the machine body 100. A connecting hole 120 is formed on the machine body 100 along the direction of motion of the carrier plate 200. A connecting shaft 750 passes through the connecting hole 120 to securely connect the connecting rod 730 to the carrier plate 200. The drive wheel 710 is rotatably disposed on the exterior of the machine body 100 and is connected to the rotor of the generator 300 via a belt 740. The connecting rod 720 has two ends that are connected to the drive wheel 710 and the connecting rod 730 via rotating shafts. It is understood that when the carrier plate 200 reciprocates up and down within the body 100, the carrier plate 200 drives the drive wheel 710 to rotate via the connecting rod 720, and the drive wheel 710 drives the rotor of the generator 300 to rotate via the belt 740, thereby converting the linear motion of the carrier plate 200 into the rotational motion of the rotor of the generator 300. Of course, in other embodiments, the motion conversion structure can also be a gear rack mechanism, a cam mechanism, a screw transmission mechanism, or other mechanical transmission structure capable of converting linear motion into rotational motion.

[0028] In some embodiments, in order to store the electrical energy output by the generator 300, the kinetic energy recovery and power generation device may further include an energy storage cabinet (not shown) connected to the generator 300. The energy storage cabinet may adopt existing technology, for example, the energy storage cabinet adopts a structure that is the same as or similar to the energy storage device in patent publication number CN222301589U.

[0029] In some embodiments, a jaw crusher mechanism driven by a drive wheel 710 can also be housed within the machine body 100. The drive wheel 710 is connected to the starter via a belt. The jaw crusher primarily consists of a stationary jaw plate, a movable jaw plate, an eccentric shaft, a toggle plate (safety device), an adjustment seat, and a movable jaw pull rod. The drive wheel 710 is driven by the starter. When the starter is activated, the drive wheel 710 begins to rotate, driving the eccentric shaft to cause the movable jaw plate to oscillate periodically. The drive wheel 710 acts as an energy storage mechanism, storing energy during the idle stroke of the movable jaw plate and releasing it during the working stroke, ensuring a more stable and smooth crushing process. Furthermore, when the crushing operation is complete and the machine is shut down, the drive wheel 710 does not immediately stop rotating due to inertia. Since the drive wheel 710 is connected to the rotor of the generator 300 via a belt, the drive wheel 710 continues to rotate for a period of time, converting the remaining kinetic energy of the drive wheel 710 into stored electricity.

[0030] According to another aspect of an embodiment of the present invention, a method for recovering kinetic energy of ore 900 using the above-mentioned device for power generation by kinetic energy recovery is provided, comprising the following steps: S100, installing the body 100 of the device for generating electricity by utilizing kinetic energy recovery at the foot of a mine, with the opening of the body 100 aligned with the mining location of the ore 900; S200: The ore 900 falls from the mining position, and the gravitational potential energy of the ore 900 is converted into kinetic energy. The falling ore 900 eventually falls into the body 100 through the opening of the body 100; S300: After the ore 900 falls into the machine body 100, it will be caught by the carrying plate 200. The carrying plate 200 moves up and down under the action of the spring device. The carrying plate 200 drives the generator 300 to rotate and generate electricity through the motion conversion structure, thereby realizing the recovery of the kinetic energy of the ore 900. S400: During the reciprocating movement of the supporting plate 200, the fixed crushing structure on the supporting plate 200 automatically takes effect, specifically including: After the ore 900 enters the machine body 100, it pushes the stopper 620 to turn downward; The stopper 620 always contacts the ore 900 under the elastic force of the first elastic member 640 ; When the ore 900 dropped on the carrying plate 200 tends to move upward away from the carrying plate 200, the stopper 620 clamps the ore 900 under the elastic force of the first elastic member 640 and restricts its upward movement, thereby stably restraining the ore 900 on the carrying plate 200. At the same time, during the turning process, the stopper 620 drives the extrusion member 630 to move toward the ore 900 through the transmission cooperation between the driving gear 621 and the rack 631, thereby achieving extrusion and crushing of the ore 900.

[0031] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
