Description

Technical Field

[0001] The utility model relates to the field of mine transportation, and specifically provides a mine transportation device with a gravity energy storage function. Background Art

[0002] Gravity energy storage technology mainly recycles the gravitational potential energy of heavy objects and converts it into forms such as electrical energy for storage and reuse. For example, one way to implement gravity energy storage technology is to transport heavy objects from a low position to a high position by using abandoned wind and solar power, and use the gravitational potential energy of heavy objects to generate electricity when electricity is needed. That is, in the process of storing gravitational potential energy, heavy objects are transported from a low position to a high position. In the process of releasing gravitational potential energy, the released gravitational energy is converted into electrical energy. Since the energy storage process requires a motor to drive the heavy objects to a high place, the belts and other related transport mechanisms need to be kept taut at all times. When directly applied to a scenario that only involves releasing gravitational potential energy, the power generation efficiency will be reduced due to the large starting resistance.

[0003] A mine is a typical scenario that only involves the release of gravitational potential energy. Specifically, since mines usually have the characteristics of long transmission distances, most of them are projects (isolated projects) that mainly use self-powered power generation such as diesel power, wind and solar power generation, and the power generation and power consumption are less related to the external power grid. At the same time, considering that the ore in the mine happens to need to be transported to a lower place, it is necessary to make full use of the various resources in the mine plant to provide power for the equipment in the plant or the equipment used to transport the ore. Among the various resources, it is quite necessary to recover the gravitational potential of the ore (such as further conversion into electrical energy, etc.) when the ore is transferred to the transport vehicle.

[0004] Accordingly, the art needs a new technical solution to solve the above problems. Utility Model Content

[0005] The utility model aims to at least partially solve the above technical problems. Specifically, it provides a device that can optimize the recovery of gravitational potential energy in combination with the "isolated island" scene attributes of the mining area to at least a certain extent.

[0006] In view of this, the utility model provides a mining transportation device with a gravity energy storage function, which includes: a base, the base having a first part and a second part, and the ore to be transported can be transported to a target position via the first part and the second part in sequence; a walking mechanism, the ore to be transported can be carried on the walking mechanism, and the walking mechanism can move along the first part and the second part; and an energy storage mechanism, which can be connected to the walking mechanism at least during the period when the walking mechanism moves along the second part, so as to recover the gravitational potential energy released by the ore to be transported during the period when the ore passes through the second part.

[0007] With such a configuration, it is possible to recover a portion of the gravitational potential energy of the ore that needs to release the gravitational potential energy.

[0008] It is understandable that those skilled in the art can determine the configuration, stroke, and gravitational potential energy relationship of the first and second parts according to actual needs. For example, the energy storage mechanism is a generator or other device / mechanism capable of recovering gravitational potential energy.

[0009] For the above-mentioned mining transportation device with gravity energy storage function, in a possible implementation manner, the first part includes an inclined part that is inclined downward along the transportation direction of the ore to be transported.

[0010] By such a configuration, it is possible to seek to use the deadweight of the ore to enable the traveling mechanism to realize its movement in the first part. For example, it can be only by the deadweight of the ore, or a corresponding drive transmission mechanism can be provided at the same time.

[0011] For the above-mentioned mining transport device with gravity energy storage function, in a possible implementation manner, the angle between the inclined portion and the horizontal direction is a value between 10-20°.

[0012] For the above-mentioned mining transportation device with gravity energy storage function, in a possible implementation, the second part includes at least one energy storage sub-part, and the angle between at least one part of the energy storage sub-part and the horizontal direction is greater than the angle between the inclined part and the horizontal direction.

[0013] With such a structure, it is possible to better recover the gravitational potential energy.

[0014] For the above-mentioned mining transport device with gravity energy storage function, in a possible implementation manner, the energy storage sub-part includes a vertical part.

[0015] Through such a composition, a possible form of the energy storage sub-part is given.

[0016] For the above-mentioned mining transportation device with gravity energy storage function, in a possible implementation manner, when the energy storage sub-sections include multiple ones, adjacent energy storage sub-sections are connected or connected through transition sections.

[0017] Through such a configuration, a possible way of forming the second part with multiple energy storage subparts is provided.

[0018] For the above-mentioned mining transportation device with gravity energy storage function, in a possible implementation manner, the first part and the second part are directly connected to each other or connected to each other through a transition part.

[0019] This configuration provides a possible way for the first part and the second part to form the stroke of the walking mechanism.

[0020] For the above-mentioned mining transportation device with gravity energy storage function, in a possible implementation manner, the mining transportation device with gravity energy storage function includes a tensioning mechanism, and the traveling mechanism can be connected to the energy storage mechanism by means of the tensioning mechanism.

[0021] With such a configuration, it is possible to recover the gravitational potential energy of the ore to be transported by switching the tensioning mechanism at least during the movement of the traveling mechanism along the second portion.

[0022] For the above-mentioned mining transport device with gravity energy storage function, in a possible implementation manner, the tensioning mechanism includes a hydraulic push rod, and the hydraulic push rod can be pushed out to approach the walking mechanism when hydraulic pressure is applied.

[0023] Such a configuration provides a possible structural form of the tensioning mechanism.

[0024] For the above-mentioned mining transport device with gravity energy storage function, in a possible implementation, the traveling mechanism includes a belt, and the hydraulic push rod pushes out the pulley when hydraulic pressure is applied, so that the pulley is (tightly) abutted against the traveling mechanism.

[0025] Through such a configuration, a specific way of achieving belt tensioning is provided.

[0026] For the above-mentioned mining transportation device with gravity energy storage function, in a possible implementation manner, the energy storage mechanism includes one or a plurality of energy storage mechanisms arranged along the height direction.

[0027] With such a configuration, it is possible to realize concentrated recovery or layered recovery of the ore to be transported.

[0028] For the above-mentioned mining transportation device with gravity energy storage function, in a possible implementation, the energy storage mechanism is a generator, and the generator can charge a transportation vehicle used to transport the ore to be transported.

[0029] Through such a structure, a specific way of reusing the gravitational potential energy after recovery is provided.

[0030] In a preferred embodiment of the utility model, the mine transportation device with gravity energy storage function realizes the recovery of gravity potential energy under the premise of ensuring the transportation reliability of the ore. For example, in the transportation journey corresponding to the first part, the smooth movement of the ore is achieved with the help of gravity potential energy, and in the transportation journey corresponding to the second part, the gravity potential energy of the ore is recovered and converted into electrical energy to charge the transport vehicle responsible for transporting the ore. Since there is no need to lift the ore to a high position, the structure is simplified. Based on the recovery and reuse of gravity potential energy, the device of the utility model is more suitable for mining scenes with "isolated island" attributes. BRIEF DESCRIPTION OF THE DRAWINGS

[0055] In addition, in order to better illustrate the present invention, many specific details are given in the following specific embodiments. Those skilled in the art should understand that the present invention can also be implemented without certain specific details. In some examples, the principle of converting gravitational potential energy into electrical energy, which is well known to those skilled in the art, is not described in detail in order to highlight the main purpose of the present invention.

[0056] For the mining scene, the ore to be transported is at a high position, and the position where the ore is moved away from the mine is at a low position. Therefore, the gravitational potential energy of the ore exists objectively, that is, there is no need for the link of storing gravitational potential energy as mentioned in the background technology to have the conditions for releasing gravitational potential energy. For example, the usual processing method is: after the transport vehicle reaches the preset low position where the ore can be moved away from the mine, the transport vehicle continues to climb to the height where the ore is located, and after loading the ore, it first returns to the low position, and then leaves the mine. In this way, not only is it necessary to increase the energy consumption of the transport vehicle, but also wastes the gravitational potential energy of the recyclable ore. Based on this, the inventor proposes a mine transportation device with a gravity energy storage function in the utility model. Specifically, the mine transportation device with a gravity energy storage function in the utility model can directly transport high-level ore to a low place (using the gravitational potential energy of the ore), thereby reducing the round-trip process of the transport vehicle in the mine. Furthermore, in the process of directly transferring the high-level ore to the low-level position, the gravitational potential energy of the ore can be recovered.

[0057] Main reference Figure 1 and Figure 2 , Figure 1 A schematic diagram showing the structure of a mining transport device with a gravity energy storage function according to an embodiment of the utility model is shown. Figure 2 A schematic diagram of the state of a mine transportation device with a gravity energy storage function according to an embodiment of the utility model when arranged on a mine is shown. In a possible implementation, a mine transportation device 100 with a gravity energy storage function is arranged on a mine 200, and is mainly used to transport ore 201 at a high position in the mine to a transport vehicle 300 at a low position. In this process, the gravitational potential energy of the ore 201 is recovered and converted into electric energy. For example, in this example, the converted electric energy can be used to replenish the power battery 301 of the transport vehicle 300. For example, the target position can be a transport vehicle 300 at a low position, or it can be a certain position corresponding to the low position. The electric energy can be used to replenish the power battery 301 of the transport vehicle 300, and it can also provide electric energy for other equipment that needs electric energy.

[0058] In a possible embodiment, the mine transport device 100 with gravity energy storage function mainly includes a steel frame 1 fixed to the mine as a base, and the steel frame 1 has an inclined portion 21 ( Figure 1 The slope part at the top of the middle part is mainly used to move the ore by using the gravitational potential energy of the ore, such as moving from left to right to the vertical part) and the vertical part 22 ( Figure 1 The vertical part on the right side of the middle part, in which the gravitational potential energy of the ore can be recovered), the ore 201 can be transported to the transport vehicle 300 along the inclined part and the vertical part in turn. The inclined part 21 and the vertical part 22 are paved with a walking mechanism that can carry the ore 201 and walk along the inclined part 21 and the vertical part 22. The mine transportation device 100 with gravity energy storage function also includes a generator 4, which is mainly used to selectively recover the gravitational potential energy. For example, in this example, the generator 4 starts to recover the gravitational potential energy of the ore after the ore reaches the vertical part. For example, the angle between the inclined part and the horizontal direction is a value between 10-20° (exemplarily, the angle between the two is 15°).

[0059] Reference Figure 3 , Figure 3 Show Figure 2 This is an enlarged schematic diagram of part A in the figure. Figure 3 As shown, in this example, the walking mechanism includes a belt 3, and belt teeth 31 are arranged on the upper surface of the belt 3, and a single piece of ore 201 can be sandwiched between adjacent belt teeth 31. For example, the tooth spacing, tooth height and other parameters of the belt teeth can be designed according to the size of the ore and other specifications. The belt teeth need to ensure that the ore can be reliably held during the movement of the ore in the vertical part, thereby ensuring the reliability of ore transportation and the reliability of gravity potential energy recovery. Exemplarily, the belt teeth can be designed to be crescent-shaped, which can ensure that the ore can be reliably held during the vertical part of the journey, and on the other hand, because the crescent-shaped toothed belt is open between adjacent belt teeth when the ore reaches the lower end of the vertical part, it is convenient to smoothly drop the ore onto the transport vehicle 300.

[0060] Obviously, the combination of the belt and the belt teeth is only an exemplary description of the traveling mechanism, and those skilled in the art can flexibly determine the specific form, movement mode and specific drive transmission mode of the traveling mechanism according to the actual situation. For example, it can include but not be limited to replacing the belt teeth with a carrying structure that can accommodate one or more pieces of ore (such as a carrying body with a containing cavity such as a containing bag, etc.), replacing the belt drive with a chain drive, etc.

[0061] In this example, the steel frame 1 includes a plurality of steel frame rods arranged in a vertical direction. In the assembled state, the top of the leftmost first steel frame rod 11 corresponding to the high position corresponds to a height higher than the top of the rightmost second steel frame rod 12. In this way, the portion corresponding to the portion between the first steel frame rod 11 and the second steel frame rod 12 forms the aforementioned inclined portion 21, and the portion along the second steel frame rod forms the vertical portion 22.

[0062] It is understandable that those skilled in the art can determine the specific construction methods of the inclined part and the vertical part according to actual needs, such as through a combination of sheet metal structures.

[0063] In addition, one inclined portion and one vertical portion in this example are only an exemplary description. First, those skilled in the art can determine the specific structure of the inclined portion and the vertical portion, the stroke, number, and relative position, etc., according to actual needs. Second, those skilled in the art can flexibly adjust the degree of inclination of the inclined portion, adjust the vertical portion to a non-vertical portion with a greater degree of inclination than the inclined portion, add a transition portion between the inclined portion and the vertical portion, etc., according to actual needs.

[0064] In a possible implementation, a vertical portion is changed into multiple vertical portions or multiple energy storage inclined portions with a large inclination. Taking the energy storage inclined portion as an example, adjacent inclined portions are directly connected or connected to each other through a transition section. A generator is provided on the downstream side corresponding to each energy storage inclined portion, thereby realizing multi-layered energy recovery. For example, when the transport vehicles in a mine are parked at different heights, layered energy storage for gravitational potential energy can be realized.

[0065] In a possible implementation, the belt 3 is provided with a tensioning mechanism. When the tensioning mechanism makes the belt in a taut state, the movement of the belt can drive the rotor of the generator 4 to move, thereby converting the gravitational potential energy of the ore into electrical energy storage. When the belt is in a non-taut state, the gravitational potential energy of the ore is not recovered. In this way, if the tensioning mechanism is in a non-working state in a relatively gentle inclined part, the belt can drive the ore to slowly slide down the inclined part by the weight of the ore. After the ore reaches the vertical part, the tensioning mechanism is put into a working state, thereby making the belt in a taut state. In this way, the rotor of the generator can be driven to rotate by the belt at a relatively high speed (rapid release of gravitational potential energy), thereby converting the gravitational potential energy of the ore into electrical energy.

[0066] In this example, the tensioning mechanism includes a hydraulic push rod 5, and the hydraulic push rod 5 is provided with a hydraulic switch. A first pulley 61 and a second pulley 62 that can match the belt are provided at the top corresponding to the first steel frame rod and the second steel frame rod, and the elevation of the first pulley is higher than that of the second pulley. By turning on the hydraulic switch, the hydraulic push rod can extend upward in the vertical direction and push the second pulley to closely contact the lower surface of the belt (roughly at the intersection of the inclined part and the vertical part). For example, an anti-skid structure such as an anti-skid pattern can be provided on the inner side of the belt to ensure the transmission reliability between the belt and the rotor and improve the transmission efficiency between the belt and the rotor.

[0067] Obviously, the hydraulic push rod is only an exemplary description, and those skilled in the art can flexibly determine the specific form, setting position, movement mode, position / number of tensioning points, etc. of the tensioning mechanism according to the actual situation. For example, it may include but is not limited to: the tensioning mechanism includes one or more tensioning wheels, the position of the tensioning wheels can be adjusted and thus the tensioning state of the belt can be switched; other telescopic mechanisms such as cylinders, linear modules, etc. other than the hydraulic push rod; taking the telescopic mechanism having only one telescopic point as an example, the telescopic mechanism can move upward in the vertical direction to put the belt in a taut state, or it can put the belt in a taut state by horizontal movement or tilting movement.

[0068] Based on the above structure, the operation process of the mining transportation device with gravity energy storage function of the utility model includes two stages:

[0069] The first stage is the initial non-power generation stage. In this stage, the device is in the initial startup state, the hydraulic switch is in the closed state, the hydraulic push rod 5 does not exert force, the second pulley 62 corresponding to the second steel frame rod 12 is in a low position, the belt 3 is in a loose state, the friction resistance of the entire belt 3 is small, and the rotor of the generator 4 does not rotate.

[0070] After the ore to be transported is transported to the belt, since the elevation of the second pulley 62 is lower than that of the first pulley 61 and the ore has a large deadweight, it is expected that the belt can be driven to rotate under the action of the deadweight of the ore. When the amount of ore transported to the belt increases to a certain amount, the ore can stably move on the top inclined part under the action of its deadweight, such as from the top inclined part 21 to the upper end of the vertical part 22.

[0071] The second stage is the energy storage power generation stage. In this stage, the belt 2 is driven by the weight of the ore until the ore reaches the upper end of the vertical part 22. Since the direction of movement of the belt is basically consistent with the direction of gravitational potential energy, the power will increase rapidly and the speed of the belt will also increase significantly.

[0072] At this time, the hydraulic switch is turned on, and the hydraulic push rod 5 pushes the second pulley 62 upward to adjust the belt 3 to a taut state. In this way, the belt 3 can drive the rotor of the generator 4 to rotate, and the generator 4 enters the energy storage and power generation state.

[0073] At this time, the transport vehicle 300 is parked near the generator 4 of the mine transportation device with gravity energy storage function. If the power battery 301 is connected to the generator 4, the power battery 301 of the transport vehicle 300 can be charged through the generator 4.

[0074] It can be seen that in the preferred embodiment of the utility model, the scene corresponding to the mine with the attribute of "isolated island" can be understood as focusing on transportation or rigid demand, while the power generation corresponding to the gravity energy storage (recovery of gravity potential energy) can be understood as a subsidiary product. Compared with the two operating trajectories corresponding to the storage of gravity potential energy link and the release of gravity potential energy link in the background technology, when designing the gravity energy storage link of the mine transportation device with gravity energy storage function, there is no need to consider the factors related to the energy storage efficiency of the storage of gravity potential energy link that transports heavy objects (ores) to high positions, such as motor efficiency, but only need to consider how to maximize the use of gravity potential energy for power generation. In this way, on the basis of recycling gravity potential energy, it is expected to ensure the transportation reliability of ore by simplifying the structure.

[0075] So far, the technical solution of the present invention has been described in conjunction with the preferred embodiments shown in the accompanying drawings. However, it is easy for those skilled in the art to understand that the protection scope of the present invention is obviously not limited to these specific embodiments. Without departing from the principle of the present invention, those skilled in the art can make equivalent changes or substitutions to the relevant technical features, and the technical solutions after these changes or substitutions will fall within the protection scope of the present invention.
