Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0031] like Figures 1 to 7 As shown, a multi-condition test system for track-mounted gravity energy storage includes a steel frame assembly, a track module 200, a power station module 500, an experimental train 700, and a test station control center. Please refer to [link / reference needed]. Figure 1 , Figure 2 The steel frame assembly includes a low-level steel frame platform 101, a ramp steel frame platform 102, and a high-level steel frame platform 103 connected in sequence from low to high, which provide the load-bearing foundation and operating area for the test system.

[0032] The high-level steel frame platform 103 is equipped with multiple test platforms 1031 of different heights. Any test platform 1031 can be connected to the inclined steel frame platform 102, realizing the switching settings of different slopes of the inclined steel frame platform 102. In this embodiment, three sets of test platforms 1031 are selected.

[0033] Firstly, multiple sets of track modules 200 and power station modules 500 are laid on the low-position steel frame platform 101, the inclined steel frame platform 102, and the test platform 1031. The laying of track modules 200 and power station modules 500 forms a track line for the experimental train 700 to move up and down. When the experimental train 700 is connected to the power station module 500, a transmission connection is established.

[0034] The power station module 500 is provided with a driving mode or a power generation mode, that is, when the power station module 500 is in the driving mode, the power station module 500 is used to drive the experimental train 700 to run on the track line, and when the power station module 500 is in the power generation mode, the power station module 500 is used to convert the gravitational potential energy of the experimental train 700 into mechanical kinetic energy and then into electrical energy when the experimental train 700 runs from top to bottom from the inclined steel frame platform 102. Regardless of whether the power station module 500 is in the driving mode or the power generation mode, the running speed of the power station module 500 as the driving or the rotation speed of the power station module 500 as the power generation is controlled by the test station control center, that is, the test station control center can adjust the running speed of the power station module 500 in different working condition tests.

[0035] In actual application, at least one set of power station modules 500 are arranged on the low-position steel frame platform 101, the test platform 1031 and the inclined steel frame platform 102. The power station modules 500 arranged on the low-position steel frame platform 101 and the test platform 1031 adopt the driving mode. As a preferred arrangement, the power station modules 500 are arranged on one end of the low-position steel frame platform 101 and the test platform 1031 close to the inclined steel frame platform 102. The test station control center adjusts the driving speed of the power station modules 500 on the low-position steel frame platform 101 and the test platform 1031 to realize the running speed of the experimental train 700 entering the inclined steel frame platform 102.

[0036] The power station modules 500 on the inclined steel frame platform 102 can adopt the driving mode or the power generation mode. Conventionally, a plurality of power station modules 500 are arranged, and the running mode and the running speed of the power station modules 500 are controlled by the test station control center. The power station modules 500 on the inclined steel frame platform 102 are provided with data acquisition sensors. The data acquisition sensors are used to acquire the running data of the corresponding power station modules 500 during the test running and feed back the running data to the test station control center. Conventionally, the data acquisition sensors are used to acquire the associated model data obtained by the power station modules 500 in different working conditions when the power station modules 500 are in the power generation mode, and then obtain the power generation efficiency in the corresponding working condition.

[0037] The test station control center compares different working condition tests according to the arrangement position of the power station module 500, the building height of the high-position steel frame platform 103, the arrangement interval of the power station module 500, the load condition of the experimental train, the running speed and other conditions, feeds back the data of the power station module 500 monitored by the data acquisition sensor, analyzes the efficiency attenuation law, correlates the model, selects the most effective parameter combination, and improves the power generation efficiency of the final gravitational energy storage.

[0038] In the embodiment, a heavy block hoisting mechanism can be arranged on one side or directly above the low-position steel frame platform 101 to load and unload the load weight on the experimental train 700. The heavy block hoisting mechanism can be electrically connected to the test station control center or can operate independently to adjust the load according to the load demand of the test station.

[0039] In this embodiment, the track module 200 and the power station module 500 have the same laying size and can be arbitrarily assembled and replaced. The position of the power station module 500 can be adjusted. The track module 200 and the power station module 500 are respectively provided with a first track 202 and a second track 502. The first track 202 and the second track 502 are connected and matched. The power station module 500 includes a power station 503 that can be detachably installed on the side of the second track 502. When the power station 503 is connected to the experimental train 700, the power transmission is connected.

[0040] Please see Figure 3 The track module 200 includes a first steel frame laying plate 201, a first track 202, and a first fastener. That is, the first steel frame laying plate 201 is connected to the first track 202, and the first steel frame laying plate 201 is installed and connected to the low-position steel frame platform 101, the inclined steel frame platform 102, and the test platform 1031 through the first fastener.

[0041] Each test platform 1031 is fixedly connected to a high-level rail docking frame 300 on the high-level steel frame platform 103. Any test platform 1031 can be docked with the inclined steel frame platform 102 via the high-level rail docking frame 300. For details, please refer to [link to relevant documentation]. Figure 5 The high-position rail docking frame 300 includes a high-position mounting frame 301 and a high-position rail 302 fixedly connected to the high-position mounting frame 301. When the test platform 1031 is connected to the inclined steel frame platform 102 through the high-position rail docking frame 300, the corresponding high-position rail 302 is matched and connected to the rail of the adjacent rail module 200 or power station module 500.

[0042] In addition, the bottom end of the ramp steel frame platform 102 is connected to a low-position rail docking frame 400. Please refer to [link / reference needed]. Figure 6 The low-position rail docking frame 400 includes a low-position mounting frame 401 and a low-position rail 402 fixedly connected to the low-position mounting frame 401. Multiple sets of low-position rail docking frames 400 are provided to cooperate with high-position rail docking frames 300, and the low-position rails 402 of the multiple sets of low-position rail docking frames 400 have different curvatures. In this way, when the inclined steel frame platform 102 selects high-position rail docking frames 300 of different heights, a suitable low-position rail docking frame 400 can be selected to ensure the docking between the rails. Furthermore, the low-position rail docking frame 400 docks with the low-position steel frame platform 101.

[0043] In this embodiment, the slope steel platform 102 is designed to switch three kinds of slope (10° / 15° / 20°), which can verify the influence of different slopes, experimental train speed and load on the system performance and energy conversion efficiency. A lifting device 600 is installed on the top of the test platform 1031, which is used to lift the slope steel platform 102 when switching the slope, so as to realize the docking with the test platform 1031 of different heights.

[0044] Please refer to Figure 1 、 Figure 2 , the low-position steel platform 101, the slope steel platform 102 and the test platform 1031 are all paved with power station modules 500. Specifically, please refer to Figure 4 , the power station module 500 includes a second steel laying plate 501, a second fastener, a second track 502 and a power station 503, that is, the second track 502 is on the second steel laying plate 501, the power station 503 is detachably installed on the second steel laying plate 501 on the side of the second track 502, and the second steel laying plate is installed and connected on the low-position steel platform 101, the slope steel platform 102 and the test platform 1031 by the second fastener.

[0045] Preferably, the second steel laying plate 501 of the power station module 500 has the same laying width size as the first steel laying plate 201 of the track module 200, so that the track module 200 and the power station module 500 can be replaced with each other, so that the number and spacing of the power stations 503 on the low-position steel platform 101, the slope steel platform 102 and the high-position steel platform 103 can be adjusted to meet the requirements of the gravitational energy storage test under different spacing and number of power stations 503.

[0046] At least one set of power station modules 500 can be arranged on the test platform 1031, multiple sets of power station modules 500 can be arranged on the slope steel platform 102, and at least one set of power station modules 500 can be arranged on the low-position steel platform 101. When the test platform 1031, the high-position docking track frame, the slope steel platform 102, the low-position docking track frame and the low-position steel platform 101 are docked, the first track 202, the high-position track 302, the second track 502 and the low-position track 402 are matched to form a smooth track line to ensure that the experimental train 700 can run on the track line, and the power station 503 of the power station module 500 is connected with the experimental train 700.

[0047] Each power station includes a single-sided or double-sided symmetrical power assembly, and the power assembly adopts a detachable structure. The power assembly is also connected with a tensioning mechanism for adjusting the tension of the power assembly and the experimental train 700. The tensioning mechanism adopts a mechanical tensioner or a hydraulic tensioner, and the tensioning mechanism is detachably installed. The power assembly adopts an electric motor or a generator or an electric generator dual-purpose machine.

[0048] In the test system, the power station 503 of the low-position steel frame platform 101 and the high-position steel frame platform 103 generally adopts a driving mode, and the power assembly can adopt one of an electric motor or an electric generator.

[0049] On the slope steel frame platform 102, when the experimental train 700 ascends from the low position to the high position, the power station 503 adopts a driving mode, and one of an electric motor or an electric generator can be adopted; when the experimental train 700 descends from the high position to the low position to generate power, the power station 503 adopts a power generation mode, and one of a generator or an electric generator can be adopted.

[0050] In the test system, when different electric motors, generators, and experimental trains 700 need to be verified for energy loss or power generation efficiency, the electric motor or the generator can be separately installed on the test line, and the electric motor or the generator includes a transmission friction wheel assembly. The experimental train 700 includes a driving plate. When the experimental train 700 passes through the electric motor, the electric motor drives the friction wheel assembly to rotate to drive the driving plate of the experimental train 700, thereby driving the experimental train 700 to move forward. When the experimental train 700 passes through the generator, the driving plate of the experimental train 700 and the friction wheel assembly of the generator are pressed and rubbed to drive the generator to rotate, thereby converting the gravitational potential energy of the experimental train 700 into kinetic energy of the friction wheel assembly, and converting the kinetic energy into electrical energy through the generator, storing the electrical energy, or recording the power generation amount and feeding back to the test system.

[0051] As shown in FIG. 1, the test system includes a test track 100, a low-position steel frame platform 101, a slope steel frame platform 102, a high-position steel frame platform 103, a test station control center 104, and an experimental train 700. Figure 4 In this embodiment, a conventional permanent magnet synchronous motor is used as an electric generator and motor, and the test station control center can control the power station to operate as a generator or an electric motor.

[0052] The specific structure is as follows: the power assembly includes a support seat, a friction wheel, a transmission member, and a permanent magnet synchronous motor, and the friction wheel is slidably arranged on the support seat. The friction wheel is in transmission connection with the permanent magnet synchronous motor through the transmission member. When the experimental train 700 passes through the power station 503, the friction wheel is in friction connection with the driving plate of the experimental train 700. The permanent magnet synchronous motor is in electrical connection with the test station control center.

[0053] When the experimental train 700 ascends on the slope steel frame platform 102, the test station control center can control the permanent magnet synchronous motor to operate as an electric motor to drive the experimental train 700 to ascend. When the experimental train 700 descends on the slope steel frame platform 102, the test station control center can control the permanent magnet synchronous motor to operate as a generator to generate and store power.

[0054] In the embodiment, the friction wheel is slidably arranged on the support seat through the friction wheel seat, the friction wheel seat is connected with a mechanical tensioning mechanism or a hydraulic tensioning mechanism, and the mechanical tensioning mechanism or the hydraulic tensioning mechanism can be detachably installed, so that test and test switching of each component are facilitated.

[0055] Whether it is an independent motor, a generator or a motor-generator dual-purpose machine, the power element can be detachably installed, so that different power elements can be tested in the gravity energy storage system for energy efficiency analysis.

[0056] In the embodiment, the data acquisition sensor is one or more of a voltage / current sensor, a speed / rotational torque sensor, a Hall sensor and an acceleration sensor, and is mainly used for acquiring speed, rotational torque, acceleration, voltage / current, excitation current / voltage and other data information of the power station, and feeding back the information to the test station control center for energy efficiency analysis and comparison.

[0057] In summary, the test system mainly simulates two modes of uphill transportation and downhill power generation of the energy storage power generation system, and specific principle modes are as follows.

[0059] Downhill power generation: the experimental train 700 is parked on the test platform 1031, the experimental train 700 is driven to a set speed through the power station 503 on the test platform 1031, when the tail of the experimental train 700 is separated from the power station 503 on the test platform 1031, the power station 503 stops working, then the experimental train 700 slides downward along the inclined track under the action of gravity, and drives the power station 503 on the inclined track to work to generate power, when the experimental train 700 reaches the power station 503 on the low-position steel frame platform 101, the experimental train 700 is decelerated and parked through the power station 503.

[0060] Through the test system of the application, various parameters and component switching can be flexibly adjusted, including heavy block mass, slope gradient, different power station selection, power station spacing, train node number, power station internal structure type, tensioning, friction wheel diameter, material and other performance parameter selection, corresponding energy conversion efficiency, running stability and power generation conversion rate are obtained through different parameter tests, so that the best parameter ratio is obtained.
