[0012] Compared with the prior art, the utility model has the beneficial technical effects as follows:

[0021] The utility model provides a spiral roller gravity power generation system, solves the problem that the existing gravity energy storage power generation system occupies large area, construction is limited and cannot realize current output continuous, stable. The gravity power generation system of the utility model generates electricity by heavy object driving roller, and the system operation is simple, realizes that the heavy object automatically rolls and falls in the running process through spiral path, meanwhile, the total weight of the heavy object is constant, and the system can continuously and stably run, avoids current and voltage output fluctuation, realizes high quality power generation.

[0022] Please refer to Figure 1The utility model discloses a spiral roller gravity power generation system, in other words spiral gravity roller conveyor, including spiral frame 1, spiral frame 1 is designed spirally, determines the conveying path of heavy object. Specifically, spiral frame 1 forms the spiral track that spirally drops around vertical center axis, and the pitch, diameter and spiral angle of spiral frame 1 directly influence the conveying speed and stability of heavy object, and can be customized according to actual conveying height and space limitation. A plurality of rollers 2 are distributed on the spiral track, and the roller 2 is rotatably connected with the spiral frame 1, for example, connected through bearing, so that the roller 2 in contact with the heavy object is in rotating state while the heavy object moves along the spiral track. The diameter and length of the roller are selected according to the size and weight of the heavy object, and the roller can be selected to be arranged in one or more rows. The utility model also includes one or more power generation devices, which are drivingly connected with one or more rollers 2, and the power generation device can convert the rotation of the roller into electrical energy.

[0023] More specifically, the system includes a plurality of power generation units, each of which includes a power generation device and a plurality of rollers 2 connected by a chain transmission; in other words, the rollers 2 on the spiral frame 1 are divided into multiple groups, and each group is connected with one power generation device. When the rollers rotate under the drive of the heavy object, the corresponding power generation unit realizes the function of generating electricity. Specifically, for example, several adjacent rollers form a group, or rollers spaced apart form a group; the heavy objects, for example, continuously input, form one or more rows on the spiral track, so that the power generation device generates electricity continuously, or there is a gap between adjacent heavy objects, so that different power generation devices have a phase difference, and the sum of the output electrical energy of all power generation devices is stable.

[0024] The power generation device is, for example, an electric power generation integrated machine, which has both power generation and electric functions: when storing energy, the electric power generation integrated machine uses grid power to rotate the motor bearing and do work; when generating electricity, the generator bearing rotates to generate electrical energy through the rotor, stator and other devices.

[0025] In the overall structure of the gravity energy storage system, it also includes an upper bin and a lower bin. The upper bin is a site or warehouse for storing heavy blocks at a high position, and the lower bin is a site or warehouse for storing heavy blocks at a low position. The end of the upper part of the spiral track is the heavy object descending inlet, which is connected with the upper bin through the upper bin conveying system; the end of the lower part of the spiral track is the heavy object descending outlet, which is connected with the lower bin through the lower bin conveying system. Similar to the existing gravity energy storage system, heavy objects can be conveyed and stored in the upper bin and the lower bin, and the upper bin conveying system and the lower bin conveying system are used to realize the corresponding conveying function.

[0026] As the rolling speed of a heavy object increases due to gravity, there is a need to control its descent speed near the end of the spiral track. Therefore, it is preferable to install a deceleration and buffer device near the lower end of the spiral track to adjust the descent speed of the heavy object on the spiral gravity roller conveyor. The deceleration and buffer device is, for example, a damping roller 3, which is rotatably connected to the spiral frame 1. The damping roller consumes kinetic energy during operation, and the faster the rotation speed, the greater the internal resistance. Multiple damping rollers 3 are used; in other words, multiple end rollers 2 are replaced with damping rollers 3. The heavy object is decelerated due to resistance when passing over the damping rollers 3. It is understood that the deceleration and buffer device is not limited to this. For example, it can also be a friction block separately installed outside the rollers 2, with the side, top, or bottom surface of the heavy object contacting the friction block to achieve deceleration, or a flexible component used to block the heavy object for deceleration and buffering, etc.

[0027] More preferably, one or more speed measuring devices 4 are provided near the lower end of the spiral track to detect the speed of the passing heavy object, ensuring that the speed is controllable; for example, intervention by a deceleration buffer device can be implemented only when the speed of the heavy object is too fast. More specifically, the damping roller 3 and the speed measuring devices 4 are both connected to an intelligent control device, which can detect the running speed of the heavy object in real time and intelligently and dynamically adjust the damping force of the damping roller so that the heavy object is at the set speed or stationary when it reaches the end of the spiral track.

[0028] like Figure 1 In the illustrated embodiment, the roller 2 is evenly distributed along the spiral track, and the roller 2 is located on the bottom surface of the spiral track, directly contacting the bottom surface of the weight. Optionally, the outer surface of the roller 2 is cylindrical or frustum-shaped, which ensures that the weight moves smoothly along the spiral track without colliding with the spiral frame 1 (such as the side wall of the spiral track).

[0029] It is conceivable that in some embodiments, only some of the rollers 2 are connected to the power generation equipment, while the remaining rollers rotate freely. In still other feasible embodiments, the rollers 2 connected to the power generation equipment are located on the side or top surface of the spiral track, in contact with the side or top surface of the weight, which can also achieve the effect of being driven to rotate and generate electricity as the weight moves.

[0030] The heavy objects are, for example, specially made blocks or containers holding bulk materials. Preferably, the total mass of each heavy object is a set value and is constant.

[0031] In a specific embodiment, the spiral frame also includes a support structure, which is stably installed on a bearing surface that is vertical or parallel to the ground to provide support for the spiral frame and ensure the stability of the entire conveyor during operation.

[0032] In order to further highlight the technical scheme and beneficial technical effects of the utility model, a specific operation scheme is given below. The heavy object is transported out from the upper bin and placed at the starting end of the spiral roller track. Due to the action of gravity, the heavy object starts to slide along the spiral track. In the process of moving and sliding along the spiral track path, the heavy object successively contacts each roller, and the friction force makes each roller through which the heavy object rotates, thereby driving the motor-generator integrated machine connected with each group of rollers to rotate, and further making the motor-generator integrated machine generate electricity. When the heavy object reaches the end of the spiral track, when the intelligent control device detects that the speed of the heavy object is too fast, the intelligent control device adjusts the operation power of the damping roller in real time, and adjusts the damping force of the damping roller on the heavy object to make the speed of the heavy object controllable on the spiral track, until the speed of the heavy object at the end of the spiral track is reduced to static, and finally the heavy object is transported to the lower bin through the connected conveying device.

[0033] The gravity energy storage power generation system in the traditional vertical lifting operation mode needs a large vertical space to install the lifting and lowering device of the heavy object, and has a large floor area. The spiral roller gravity power generation system of the utility model uniformly disperses the vertical height difference on the spiral track in a spiral manner, fully utilizes the space, and reduces the floor area. Therefore, the spiral roller gravity power generation system of the utility model has higher space utilization, and is suitable for use in places with limited space.

[0034] The gravity energy storage power generation system in the traditional vertical lifting operation mode is greatly limited by the terrain and space during installation and use, and has poor adaptability. The spiral roller gravity power generation system of the utility model can be flexibly arranged according to different terrain and space conditions, and has stronger adaptability. In addition, the spiral roller gravity power generation system has simple structure, and is relatively easy to maintain and manage. Therefore, the spiral roller gravity power generation system has stronger adaptability and flexibility, can be used in various complex environments while having little influence on the surrounding environment, and can reduce the maintenance cost and management difficulty.

[0035] Since the heavy object gradually slides along the spiral track and the descending process is generally stable, in addition, the speed can be accurately controlled, the high-speed impact of the heavy object due to the gravitational acceleration in the vertical up-and-down operation mode is avoided. In the vertical gravity energy storage, the heavy object falls from a high altitude, is easy to collide with the receiving device or the conveying device, causes damage to the equipment and the heavy object, and greatly reduces the service life. On the spiral gravity roller conveyor of the utility model, the rolling friction between the heavy object and the roller and the buffering effect of the damping roller greatly reduce the impact force that the heavy object or the equipment may suffer, and improve the stability and service life of the heavy object during descending.

[0036] The spiral roller gravity power generation system can realize continuous heavy object conveying.

[0037] The damping roller can stably send the heavy object out of the spiral track at a speed close to a static state with the assistance of the intelligent control device, greatly increasing the safety of the conveying device receiving the heavy object at the end of the spiral track and the stability of the system when starting conveying, and without affecting the power generation work of the heavy object acceleration section track mainly responsible for power generation.

[0038] It should be noted that the present application mainly improves the power generation process of heavy object descending, and the energy storage process of heavy object lifting can use the prior art, such as conveying through a vertical shaft, a lifting device or a ramp, or driving the roller to rotate by consuming electric energy of an electric power generation all-in-one machine to make the heavy object spiral upward along the spiral track.
