Description

Technical Field

[0001] The present application relates to the technical field of gravity energy storage, and in particular to an automatic flipping and self-locking device for supporting heavy objects for gravity energy storage. Background Art

[0002] Gravity energy storage technology leverages the height difference of structures, using surplus electricity to lift heavy objects to a certain height, converting electrical energy into gravitational potential energy – this is known as energy storage. When power is scarce, the falling object drives a generator to generate electricity, completing the conversion of gravitational potential energy into electrical energy – also known as energy release. Currently, gravity energy storage systems used in abandoned mines typically utilize a wire rope hoist system to raise and lower heavy objects. Wire ropes have complex spiral structures, subjecting them to complex forces during operation. In gravity energy storage systems, the lifting height and mass of the heavy objects directly impact the efficiency and scale of energy storage. To achieve greater energy storage capacity, the weight of the heavy objects typically reaches tons or even tens of tons. Once lifted to the top of the abandoned mine, the objects need to rest for a period of time. As the hoisting system ages, the wear and fatigue of the wire ropes due to friction and tension gradually increase. A partial break in the wire rope during this resting period can cause serious safety hazards and limit the long-term stability of the system. Utility Model Content

[0032] Specifically, in this embodiment, the lifting system 1 and the heavy object 2 are located in the center of the abandoned mine, and the platform body 3 is symmetrically installed on the ground at the left and right ends of the abandoned mine to ensure that the heavy object 2 can be placed on the platform body 3.

[0033] The automatic flipping and self-locking device for supporting heavy objects for gravity energy storage flips and self-locks the support part relative to the fixed part, so that the heavy object 2 can be placed on the support part during the gravity energy storage process, thereby reducing the energy storage system's dependence on the wire rope, extending the service life of the wire rope, and effectively improving the safety and stability of the system; when releasing energy, the lifting system 1 first drives the wire rope to lift the heavy object 2 a certain distance, and then the support part flips a certain angle to ensure that the heavy object 2 can freely fall to the bottom of the abandoned mine without contact to achieve energy release; the overall structural design of the automatic flipping and self-locking device for supporting heavy objects for gravity energy storage is scientific and reasonable, and the processing and manufacturing are simple, which ensures the continuity of the charging and discharging state of the gravity energy storage system and has good application prospects.

[0034] like Figure 3-5 As shown, in a specific embodiment, the fixing part includes a box body 31 and a box body connector 32, and the box body connector 32 is fixedly arranged on the inner wall of the box body 31; the supporting part includes a supporting platform 34 and a supporting platform connector 35, and the supporting platform 34 is located at the top of the box body 31, and the supporting platform connector 35 is fixedly arranged at the bottom of the supporting platform 34, and the connecting rod mechanism 4 connects the box body connector 32 and the support platform connector 35.

Specifically, two through holes are provided on the first connecting rod 41 and the second connecting rod 42, respectively located at both ends of the connecting rod. One through hole on the first connecting rod 41 is used to install the transmission shaft 51, and the other through hole is used to install the radial shaft 45. The two through holes on the second connecting rod 42 are both used to install the radial shaft 45; the through holes on the first connecting rod 41 and the second connecting rod 42 are limited by a sleeve 44 and sealed by an end cover 46. The end cover 46 is fixed to the first connecting rod 41 or the second connecting rod 42 by 6 screws. In addition, the driving mechanism 5 includes a transmission shaft 51 and a motor 52. The side wall of the box connector 32 is installed with a bearing 43 through a through hole. The transmission shaft 51 is connected to the box connector 32 through the bearing 43. The transmission shaft 51 connects the output end of the motor 52 and the first connecting rod 41.

[0036] Specifically, in the above embodiment, the support platform 34 and the housing 31 are the primary supporting components, and are respectively secured to the support platform connector 35 and the housing connector 32 via bolts 30. A first connecting rod 41 and a second connecting rod 42 are mounted between the support platform connector 35 and the housing connector 32. Bearings 43 are installed in the through-holes of the first and second connecting rods 41, 42, and power is transmitted via a drive shaft 51 and a radial shaft 45. Sleeves 44 limit the through-holes of the first and second connecting rods 41, 42, and the through-holes of the housing connector 32. End caps 46 seal the through-holes of the first and second connecting rods 41, 42, and the support platform connector 35, respectively. Each end cap 46 is secured to the first and second connecting rods 41, 42, and the support platform connector 35 via six screws. The first and second connecting rods 41, 42 enable the support platform 34 to tilt a certain angle along the lifting direction of the heavy object 2.

[0037] The box body 31 includes three bolt 30 holes, and the box body connector 32 is fixed to the box body 31 by means of bolts 30; there is another through hole, in which a bearing 43 is installed for transmitting the power brought by the transmission shaft 51; the box body connector 32 is L-shaped, with three bolt 30 holes and one through hole on the long side and one through hole on the short side; wherein, both through holes are installed with bearings 43 for transmitting the power brought by the transmission shaft 51; the support platform 34 includes three bolt 30 holes, which are used to fix the support platform connector 35 on the box body 31, and the support platform connector 35 includes three bolt 30 holes and two through holes, and both through holes are installed with bearings 43 for transmitting the power brought by the radial shaft 45. The two through holes are sealed with end covers 46, and the end covers 46 are fixed to the support platform connector 35 by 6 screws.

[0038] like Figure 3-5 As shown, in a specific embodiment, the reset mechanism 6 includes a reset spring 61, a first fixed column 33 is provided on the box connecting member 32, a second fixed column 36 is provided on the support platform connecting member 35, and the reset spring 61 connects the first fixed column 33 and the second fixed column 36.

[0039] like Figure 6As shown, in a specific embodiment, the support platform 34 has a first position and a second position. In the first position, the support platform 34 is attached to the top of the box body 31. In the second position, the support platform 34 is flipped upward at a preset angle relative to the box body 31. When the weight 2 is lifted upward and contacts the lower surface of the support platform 34, the weight 2 moves the support platform 34 from the first position to the second position with the help of the connecting rod mechanism 4; after the weight 2 is separated from the support platform 34, the support platform 34 moves from the second position to the first position under the action of the return spring 61 and self-locks. When the weight 2 releases energy when descending, the driving mechanism 5 drives the connecting rod mechanism 4 to move, so that the support platform 34 moves from the first position to the second position.

[0040] More specifically, the working process and principle of the automatic flipping and self-locking device for gravity energy storage heavy object support are as follows:

[0041] When the weight 2 is lifted to the point where the lower surface of the support platform 34 contacts the upper surface of the weight 2, the weight 2 drives the support platform 34 to flip a certain angle with the help of the first connecting rod 41 and the second connecting rod 42; when the upper surface of the weight 2 contacts and separates from the lower surface of the support platform 34, the support platform 34 returns from the open state to the closed state under the action of the spring restoring force and self-locks, and the weight 2 can now be placed on the support platform 34. When releasing energy, the weight 2 is first lifted a certain distance by the lifting system 1, and then the motor 52 drives the transmission shaft 51 to transmit power to the first connecting rod 41 and the second connecting rod 42. Under the action of the first connecting rod 41 and the second connecting rod 42, the support platform 34 can flip a certain angle, and the weight 2 can fall to the bottom of the abandoned mine without contact. The support platform 34 gradually returns from the open state to the closed state under the action of the spring restoring force. It should be noted that the use of two symmetrical support platforms 34 in the gravity energy storage system can achieve the distribution of the weight of the weight 2, thereby ensuring the posture balance of the weight 2 in the static engineering.

[0042] The above are merely preferred embodiments of the present application and are not intended to limit the present application. Those skilled in the art will readily appreciate that various modifications and variations are possible. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present application shall be included within the scope of protection of the present application.
