Description

Technical Field

[0001] The utility model relates to the technical field of gravity energy storage equipment, in particular to a mountain rail vehicle type gravity energy storage system. Background Art

[0002] Gravity energy storage is one of the energy storage technologies for peak-shaving and valley-filling of electricity. Its working principle is: when electricity consumption is low, heavy objects (such as concrete blocks and water) are lifted to a certain height and stored through electricity, and the electrical energy is converted into potential energy and stored; when electricity consumption is high, these heavy objects are allowed to fall, driving the generator to generate electricity, and the stored potential energy is converted into electrical energy. Of course, it can also be used to solve the problem of unstable power generation of photovoltaic power generation and wind power projects. Under the peak-shaving and valley-filling of gravity energy storage, the power generation output of photovoltaic power generation and wind power projects can stably supply electricity to the power grid to eliminate the waste of clean energy such as "abandoning wind and abandoning light".

[0003] Among the existing gravity energy storage technologies, there is a mountain rail vehicle gravity energy storage system that utilizes the slope of the mountain, that is, the height difference. When storing energy, the load-carrying vehicle needs to climb up the slope, and the use of smooth rollers is prone to slipping on the track. For this reason, relevant technicians have developed a drive gear such as announcement number CN219295378U, and set a corresponding rack on the track surface. However, since the drive gear and rack need to bear weight and wear more, after running for a period of time, a large noise will be emitted due to the fact that the teeth between the drive gear and the rack are no longer tightly matched, which needs to be improved. Utility Model Content

[0004] A technical problem to be solved by the present application is to overcome the defects of the above-mentioned related technologies and provide a mountain rail vehicle-type gravity energy storage system with low noise and long service life.

[0005] The technical solution adopted by the utility model to solve the technical problem is: a mountain rail vehicle type gravity energy storage system, including a track and a load-carrying vehicle for transporting energy storage blocks, the load-carrying vehicle is provided with an electric generator and a driving gear connected in a transmission manner, the electric generator is electrically connected to the busbar, the track is erected on supporting piles, and the bottom surface of the track is a rack; the load-carrying vehicle is provided with load-bearing wheels, the load-bearing wheels are arranged on the track and rollingly cooperate, the driving gear is arranged under the track, and the driving gear is meshed with the rack.

[0006] Compared with the related art, the utility model has the following advantages: the track is set up on the supporting piles to avoid being affected by the terrain, and there is no need to level the slope, thereby reducing the construction cost; and the rack matched with the driving gear can be set to the bottom surface of the track, and the support is formed by the load-bearing wheels separately provided by the load-bearing vehicle and the track surface, so that the driving gear and the rack are no longer used as supporting parts, thereby reducing the wear and noise between the two and extending the service life.

[0007] As an improvement, the cross-sections of the load-bearing wheel and the driving gear are both H-shaped, and the track is clamped between the load-bearing wheel and the driving gear. The load-bearing wheel and the driving gear are clamped on the track, which can effectively prevent the load-carrying vehicle from derailing.

[0008] Preferably, there are two load-bearing wheels, which are arranged on a single track. The single track can be used for operation, thus reducing construction costs. BRIEF DESCRIPTION OF THE DRAWINGS
