Description

Technical Field

[0001] The utility model relates to power generation equipment, in particular to a high-efficiency power generation group device. Background Art

[0002] In mining and quarrying operations, rock crushers play an extremely critical role. They usually use huge flywheels as power storage devices to provide enough kinetic energy to crush hard rocks. The flywheels of some large rock crushers can weigh up to 30 tons, which means that they contain huge kinetic energy when rotating at high speed.

[0003] In order to drive these large flywheels to their operating speed, powerful starters are required. These starters are usually powered by electricity or fossil fuels, which consume a lot of energy. Every time the rock crusher is started and operated, a continuous power input is required to keep the flywheel spinning at a high speed to ensure sufficient kinetic energy to break the rock. This energy demand is extremely large, resulting in high operating costs for quarrying operations.

[0004] However, the inventors found in long-term quarrying operations that when the crusher stops working and the power input is turned off, these giant flywheels do not stop rotating immediately. Due to their greater inertia, the flywheel can continue to rotate at high speed for tens of minutes under no-load conditions. During the entire deceleration process, the kinetic energy stored in the flywheel will gradually be dissipated by mechanical friction and air resistance, resulting in a large amount of energy being wasted.

[0005] Therefore, the inventor believes that how to effectively utilize the residual rotational kinetic energy of the flywheel when the crusher is shut down to avoid such energy waste has become a technical problem that needs to be solved urgently. Utility Model Content

[0067] The high-efficiency power generation device according to an embodiment of the utility model is described in detail below with reference to the accompanying drawings.

[0068] Reference Figure 1 to Figure 2 As shown, the high-efficiency power generation device provided according to the embodiment of the utility model includes a flywheel device 10, a starter 20, a second pulley 11 and a generator 30.

[0069] Specifically, the flywheel device 10 has a rotating shaft 101, a first pulley 102 and a flywheel 103, wherein the first pulley 102 and the flywheel 103 are both arranged on the rotating shaft 101. The flywheel device 10 should be understood as any mechanical device containing a flywheel in the prior art, for example, a crusher such as a jaw crusher, a hammer crusher, etc. having a flywheel 103, or an engine containing a flywheel 103, etc. The flywheel 103 is a heavy metal disc mounted on the rotating shaft 101, usually made of high-density metal such as iron or lead. As the main kinetic energy storage body, the flywheel 103 contains huge kinetic energy when rotating. The first pulley 102 is also mounted on the rotating shaft 101. Exemplarily, the first pulley 102 and the flywheel 103 are respectively mounted at both ends of the rotating shaft 101.

[0070] The starter 20 is connected to the first pulley 102 through the first transmission belt 21 to drive the rotating shaft 101 and the flywheel 103 to rotate. The starter 20 can be a starter 20 using electricity, diesel, gasoline, etc. as energy. After the starter 20 is started, the first pulley 102 can be driven by the first transmission belt 21, and then the rotating shaft 101 and the flywheel 103 on the rotating shaft 101 can be driven to rotate through the first pulley 102. In other words, the starter 20 provides continuous power for the rotating shaft 101 and the flywheel 103 of the flywheel device 10 to meet the power requirements of the stone crushing operation.

[0071] The second pulley 11 is disposed on the rotating shaft 101 and is rotatable with the rotating shaft 101. The second pulley 11 is generally made of a high-strength alloy material. It can orbit at high speed with the rotating shaft 101 and transmit kinetic energy to the generator 30 through the second transmission belt 31.

[0072] The generator 30 is connected to the second pulley 11 through the second transmission belt 31, so as to drive the generator 30 to work and generate electricity through the rotating shaft 101. The generator 30 is mainly used to collect residual kinetic energy and convert it into electrical energy output. As mentioned above, when the rotating shaft 101 rotates, the kinetic energy is transmitted to the generator 30 through the second transmission belt 31, so as to serve as the driving force of the generator, drive the generator 30 to work and generate electricity. The generator 30 can adopt a variety of different types of generators 30, such as a permanent magnet generator 30, an AC generator 30, etc.

[0073] It should be noted that, due to the large mass of the flywheel 103 of the flywheel device 10, even the residual inertial kinetic energy of slow deceleration has a very considerable total energy. Through the conversion of the generator 30, this part of kinetic energy is finally efficiently converted into electrical energy output, realizing efficient recycling of kinetic energy.

[0074] The advantage of the high-efficiency power generation device of this application is that there is no need to change the structure and working principle of the flywheel device 10 itself. It only needs to add a second pulley 11 and a second transmission belt 31 to the rotating shaft 101 to achieve the recycling of wasted kinetic energy, which has very good economy and practicality. In practical applications, this residual kinetic energy power generation can efficiently convert a large amount of energy that would have been wasted during the shutdown of the flywheel device 10 into electrical energy, and feed it back to the mine's power system, saving a lot of electricity costs for quarrying operations. And because of the reduced consumption of fossil fuels, the carbon emissions of the mining area are also greatly reduced, which is beneficial to environmental protection and sustainable development.

[0075] According to the high-efficiency power generation device provided by the embodiment of the utility model, the inertial kinetic energy of the flywheel 103 that continues to rotate after the flywheel device 10 is shut down is utilized, and the kinetic energy that was originally wasted is converted into electrical energy output by setting a second pulley 11 on the rotating shaft 101 and connecting it to the generator 30, thereby realizing the effective recycling of kinetic energy, reducing energy consumption, and improving the overall energy utilization efficiency, which has a significant energy-saving and environmental protection effect. In addition, in the application of mines, the flywheel device can be an ore crusher, so that it can not only reduce energy consumption and operating costs for mine quarrying operations, but also help promote efficient utilization of energy and sustainable development of the environment.

[0076] Reference Figure 1 to Figure 2 As shown, in some embodiments of the utility model, the high-efficiency power generation device further includes a third pulley 12, a first drive motor 40 and a power supply voltage stabilizing device 70, and the third pulley 12 is arranged on the rotating shaft 101. Exemplarily, the third pulley 12 and the first pulley 102 are installed at the same end of the rotating shaft 101. When the third pulley 12 rotates, it can drive the rotating shaft 101 to rotate.

[0077] The first drive motor 40 is connected to the third pulley 12 through the third transmission belt 41, so as to drive the rotating shaft 101 and the flywheel 103 to rotate through the first drive motor 40. In specific use, when necessary, the first drive motor 40 can be used to assist in driving the rotating shaft 101 and the flywheel 103 to rotate. For example, when the starter 20 is started and the rotating shaft 101 and the flywheel 103 are driven to start rotating, the first drive motor 40 can be started at the same time, so that the flywheel 103 can start rotating faster through the dual effects of the first drive motor 40 and the starter 20. For another example, after the starter 20 is stopped, the flywheel 103 rotates by inertia, and in order to make the flywheel 103 maintain a long rotation, the first drive motor 40 can be used to drive the rotating shaft 101 to rotate, so that the flywheel 103 continues to rotate, so as to maintain a longer power generation time and meet the power generation needs. For another example, in order to obtain a greater crushing force during ore crushing, the first drive motor 40 can be added as an auxiliary while the starter 20 is working, so as to improve the crushing ability and crushing efficiency of the crusher for large rocks.

[0078] The power supply voltage stabilizing device 70 is electrically connected to the power output terminal of the generator 30, and is used to convert part of the power generated by the generator 30 into a predetermined voltage, and provide it to the first drive motor 40. In other words, part of the alternating current generated by the generator 30 is converted into the required voltage by the power supply voltage stabilizing device 70, and in turn supplies power to the first drive motor 40, forming an internal cycle power generation-power supply closed loop system.

[0079] In this internal circulation power supply mode, the generator 30 efficiently converts most of the residual kinetic energy of the flywheel 103 into electrical energy output, a part of which is supplied to the first drive motor 40, and the first drive motor 40 does not need external power supply. In addition, the remaining electrical energy that is not used in the internal circulation can be supplied to other electrical equipment. Or it can be sent to the power grid through the grid-connected equipment to provide power for production and living electricity in the mining area.

[0080] The advantage of the internal circulation system is that a part of the electric energy can be used to power the first drive motor 40, and then the first drive motor 40 can be used to intervene and assist when needed, thereby improving the crushing capacity and efficiency, and increasing the power generation time and power, etc. At the same time, the power supply voltage stabilizing device 70 ensures the stability of the power supply voltage and ensures the stability of the operation of the first drive motor 40.

[0081] In some embodiments of the present invention, the high-efficiency power generation device further includes an energy storage device 80 , which is connected to the generator 30 to store another part of the electrical energy generated by the generator 30 .

[0082] The energy storage device 80 is usually composed of a large-capacity battery pack or a supercapacitor pack. These energy storage units can efficiently store the surplus electric energy output by the generator 30 to avoid wasting electric energy. The battery pack can be made of lithium-ion, lead-acid and other batteries, which have the advantages of large storage capacity and long cycle life. Supercapacitors can charge and discharge quickly and at high power, and can complement the battery pack.

[0083] The introduction of the energy storage device 80 transforms the entire device into a three-level distributed power supply mode of "generation-storage-use". The addition of the energy storage device 80 not only improves the overall operating efficiency, but also brings more application scenarios to the efficient power generation device. For example, the electric energy stored in the energy storage device 80 can also provide power for other electrical equipment at the quarrying site, such as lighting, air conditioning, living facilities, etc., to increase the proportion of self-powered power on site and reduce dependence on the power grid. The remaining electric energy can also be efficiently sent to the power grid through grid-connected equipment to provide power for other production links and community life in the mining area, realizing full utilization of resources. The energy storage device 80 can also be used as an emergency backup power supply to ensure that in the event of a power grid failure or an unexpected power outage, key equipment can temporarily obtain emergency power supply, thereby improving reliability and safety.

[0084] In some embodiments of the utility model, the high-efficiency power generation device further includes a fourth pulley 13 and a second drive motor 50, and the fourth pulley 13 is arranged on the rotating shaft 101. Exemplarily, the fourth pulley 13 and the third pulley 12 are installed at the same end of the rotating shaft 101. When the fourth pulley 13 rotates, it can drive the rotating shaft 101 to rotate.

[0085] The second drive motor 50 is connected to the fourth pulley 13 via a fourth transmission belt 51, so as to drive the rotation shaft 101 and the flywheel 103 to rotate. The power supply voltage stabilizing device 70 is also used to supply power to the second drive motor 50.

[0086] In this embodiment, similar to the first drive motor 40 in the above embodiment, the second drive motor 50 is also used to assist in driving the rotation shaft 101 and the flywheel 103 to rotate when needed. In a specific application, due to the large mass of the flywheel 103, the first drive motor 40 and the second drive motor 50 are usually not suitable for long-term continuous work, so a rotation working mode can be adopted. When necessary, the first drive motor 40 can be used to drive the rotation shaft 101 and the flywheel 103 to rotate. When a certain working time is reached, the first drive motor 40 is stopped, the second drive motor 50 is started, and the rotation shaft 101 and the flywheel 103 are driven to rotate by the second drive motor 50. During this period, the first drive motor 40 can be maintained.

[0087] In this embodiment, by configuring the second drive motor 50, it can be realized to work alternately with the first drive motor 40 in actual application scenarios, thereby ensuring and satisfying the reliability and stability of the overall device operating under high load. At the same time, it can effectively extend its service life and reduce maintenance costs.

[0088] In one embodiment of the present invention, the high-efficiency power generation device further includes a controller, which is connected to the first drive motor 40 and the second drive motor 50 to control the first drive motor 40 and the second drive motor 50 to work alternately.

[0089] In normal working mode, the controller will automatically control the start and stop and working time of the first drive motor 40 and the second drive motor 50 according to a preset strategy. For example, it can be set to actively switch to the backup motor (such as the second drive motor 50) after every 2 hours of work, shut down the main motor (the first drive motor 40) and start the cooling and maintenance process.

[0090] In addition, in application scenarios with heavy loads, the controller can synchronously start the dual power supply mode of the two drive motors according to actual needs, and dynamically adjust the power output of each motor to meet the maximum power demand of the flywheel 103.

[0091] Through the configuration of the controller, the control strategies of the first drive motor 40 and the second drive motor 50 can be automatically executed, so as to realize more intelligent work and improve work efficiency and stability.

[0092] Reference Figure 3 As shown, in some embodiments of the present invention, the high-efficiency power generation device also includes a kinetic energy collection device 60 and an energy conversion device 61. The kinetic energy collection device 60 is arranged on the ore conveyor line 90 to collect the kinetic energy of the ore during its rolling process.

[0093] The energy conversion device 61 is connected to the kinetic energy collection device 60 to convert the collected kinetic energy into mechanical energy for driving the generator 30. The generator 30 is connected to the energy conversion device 61 to generate electricity using the mechanical energy.

[0094] In the traditional ore mining process, the mined ore needs to be transported and sorted by conveyor belts or chutes, etc. In this process, the ore contains a lot of kinetic energy due to its own gravity and continuous rolling, but this kinetic energy has been ignored and wasted.

[0095] In view of this, in some embodiments, the high-efficiency power generation device is equipped with a kinetic energy collection device 60 and an energy conversion device 61, aiming to recover and fully utilize the kinetic energy of the rolling of the ores. The kinetic energy collection device 60 is arranged at a key position of the ore conveyor line 90, such as the exit of the ore chute or the turning point of the conveyor line or other low-level positions. The energy conversion device 61 connected thereto converts the collected kinetic energy into mechanical energy for driving the generator 30, thereby driving the generator 30 to generate electricity.

[0096] During the ore collection process, when the ore is transported by means of a conveyor belt or a chute, the ore rolls through the kinetic energy collection device 60, and the ore hits the kinetic energy collection device 60, and the kinetic energy of the ore is collected and stored by the kinetic energy collection device 60. The stored kinetic energy is then released and converted into regular mechanical motion by the energy conversion device 61, and then transmitted and converted by the mechanical transmission mechanism, and finally a continuous and stable power output is formed in a manner suitable for coupling with the input end of the generator 30. After receiving this power input, the generator 30 can continuously and efficiently generate electricity, and the required power source is the kinetic energy contained in the ore rolling process.

[0097] This innovative way of kinetic energy recovery and utilization not only reduces the huge energy waste in the traditional mining process, but also opens up a new energy supply channel for the entire high-efficiency power generation device, further improving the environmental protection and service life of the device.

[0098] Reference Figure 4 As shown, in one embodiment of the utility model, the kinetic energy collection device 60 includes a collision shell 601, a mass block 602 and an energy storage mechanism 603, wherein the mass block 602 is movably arranged in the collision shell 601, and the energy storage mechanism 603 is connected to the mass block 602; when the ore falls into the collision shell 601 and collides with the mass block 602, the mass block 602 obtains kinetic energy, and then the kinetic energy is stored in the energy storage mechanism 603.

[0099] The structure of the collision shell 601 is similar to a large semi-enclosed container or pipe, and its bottom or side wall is provided with an opening for the falling ore to enter the interior. The collision shell 601 is made of a solid metal or composite material and can withstand high-intensity impacts. In order to reduce resistance, the inner wall of the collision shell 601 adopts a smooth and unobstructed eddy flow line design.

[0100] A mass block 602 is movably mounted in the central region of the collision shell 601. The mass block 602 may be spherical, cylindrical, or have other geometric structures and is made of high-density metal or alloy. The mass block 602 moves in the collision shell 601 by means of bearings or slide rails.

[0101] The energy storage mechanism 603 is a device that can efficiently store kinetic energy, and it is connected to the mass block 602. The energy storage mechanism 603 can adopt various structural forms such as compressed air energy storage, pendulum energy storage, etc. Exemplarily, the energy storage mechanism 603 is a hydraulic energy storage device 80, a compressed air energy storage device 80 or a flywheel 103 energy storage device 80, and the energy conversion device 61 is a hydraulic motor, a pneumatic motor or a mechanical transmission device.

[0102] Taking compressed air energy storage as an example, it consists of a closed air storage tank and a reciprocating piston.

[0103] The working principle of the device is as follows: When the ores roll down from the height of the chute or conveyor belt, they will first enter the collision shell 601. Since the ores are of huge mass and roll at high speed, they carry a large amount of kinetic energy. When they hit the central mass block 602, this part of the kinetic energy will be transferred to the mass block 602, causing the mass block 602 to be hit and obtain huge kinetic energy and impulse. After obtaining the kinetic energy, the mass block 602 will push the energy storage mechanism 603 (such as the piston in the air storage tank) to do work, converting the kinetic energy into other forms such as compressed air for storage. The compressed air can provide power for the pneumatic motor. When the high-pressure air in the air tank is released, the pneumatic motor can be driven to work by expanding and doing work. The pneumatic motor is connected to the generator 30, which in turn drives the generator 30 to work and generate electricity.

[0104] Through this impact transmission method, the original huge kinetic energy of the ore is gradually accumulated and efficiently stored in the energy storage mechanism 603, providing a continuous source of power for the subsequent energy conversion process. This impact-type kinetic energy collection device 60 is innovatively designed and efficient, and can capture and store the kinetic energy of huge rolling stones, providing a power source for green power generation in the mining area.

[0105] In one embodiment of the present invention, there are multiple kinetic energy collection devices 60 , and the multiple kinetic energy collection devices 60 are arranged in sequence along the descending direction of the ore conveyor line 90 to form a multi-stage decreasing kinetic energy collection device 60 .

[0106] In this embodiment, multiple kinetic energy collection devices 60 are arranged in sequence along the descending direction of the conveyor line, so as to realize the hierarchical collection and gradual utilization of the kinetic energy of the ore. Since the rolling speed and kinetic energy of the ore are different when passing through different positions, the kinetic energy collection devices 60 can be installed at different positions to withstand different kinetic energy impacts. Through this multi-stage descending arrangement, the kinetic energy size of the ore at different positions can be effectively matched and utilized, and the kinetic energy can be collected and stored to the maximum extent.

[0107] The output ends of the multi-stage kinetic energy collection devices 60 can be connected in parallel to form a superimposed power. In this way, the kinetic energy stored in each kinetic energy collection device 60 can be combined into an overall power output. After receiving this power output, the generator 30 can continue to generate electricity efficiently. Compared with a single large kinetic energy collection device 60, the multi-stage decreasing layout not only matches the kinetic energy changes, but also reduces the impact strength requirements for a single device, thereby reducing the overall cost. In addition, even if one of the collection devices at one level fails, the other collection devices can still work normally and output power, ensuring the reliability and continuity of the system.
