- the heavy load of the reservoir 2 increases, thereby increasing the heavy load potential energy.
- the reversible turbine obtains electric energy from the power grid to start the reversible turbine and deliver water to the load-bearing reservoir 2.
- the amount of water (liquid) in the lower part of the reservoir 2 increases.
- the water (liquid) pressure increases and the heavy load rises;
- the heavy load can be stopped at any time during its ascent, or when the heavy load reaches the maximum lift, the travel stop touches the travel switch 281 (for insurance purposes, multiple travel stops and travel switches are used, and the travel switches are connected in series in the reversible turbine opening and closing circuit to Realize multiple insurances, then add visual monitoring and manpower monitoring on the upper part of the heavy load, and add a visible transparent liquid connector on the top of the heavy load in Figure 9 to monitor the liquid level on the upper part of the heavy load), so as to realize the stop of the heavy load moving upward;

- the heavy load collides with the reservoir 2 in a linear manner, causing the pressure on the outer vertical wall of the heavy load and the inner vertical wall of the reservoir 2 to be evenly distributed;
- FIG 8 Another preferred solution is: (see Figure 8) , also remove the above components on the outer side of the heavy-duty container, and then install a number of support structures in the gap between the outer wall of the heavy-load container and the inner wall of the heavy-duty energy storage tank 2 to support the roller.

- the alarm can be triggered and the heavy-load upward movement can be automatically stopped when the switch or relevant device is touched at the same time; and multiple reminders near the high point should be set below the stroke switch to trigger the alarm device, and then the alarm device should be set near the high point and reaching the high point.
- Manual alarm measures and related stop devices that is, multiple safety measures are adopted to ensure safety.
- One solution for the upper end outlet of the pipe that transports water (liquid) is to set it at the top of the heavy-duty storage tank and place it at the top of the heavy-duty storage tank.
- the upper end of the pipeline transporting water (liquid) is connected to a high-strength, highly reliable, wear-resistant, aging-resistant, and damage-resistant hose; another solution is to set it on the side of the upper part of the heavy-duty storage tank, which is also used to transport water and liquid.
- the upper end of the pipeline is connected to a hose with high strength, high reliability, wear resistance, aging resistance, and damage resistance (this hose is installed on the guide device or guide rail or regular device to allow the hose to move up and down under heavy loads.
- the purpose of connecting the hoses of these two solutions is to allow the turbine to pump the water (liquid) in the upper part of the heavy-load storage tank to the lower part of the heavy-load storage tank to store energy, so that it can be basically pumped out to maximize the stored energy;
- third The first solution is to locate the upper outlet of the water (liquid) pipeline at the top of the heavy-load storage tank, and then open a matching long countersunk hole at the corresponding position on the upper part of the heavy-duty storage tank.
- the radial size and length of the long countersunk hole should be larger than the matching long countersunk hole.
- the corresponding radial size and length of the water pipeline should be such that the water pipeline can pump out the water (liquid) during pumping and storage, maximize the storage energy, and be installed to prevent debris, foreign matter, solid matter, etc. from falling into this length.
