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 a gravity energy storage weight. Background Art

[0002] Gravity energy storage technology is based on the height difference of the structure. It uses surplus electricity to lift heavy objects to a certain height to realize the conversion of electrical energy into gravitational potential energy, which is the energy storage process. When electricity is scarce, the heavy objects are driven to generate electricity by the generator, completing the conversion of gravitational potential energy into electrical energy, which is also called the energy release process. At present, the gravity energy storage system used in abandoned mines usually uses a wire rope lifting system to lift and lower heavy objects. The wire rope is a complex spiral structure and has complex force conditions during operation. In the gravity energy storage system, the lifting height and mass of the heavy object directly affect the efficiency and scale of energy storage. In order to achieve a larger energy storage capacity, the mass of the heavy object usually reaches tons or even ten tons. When the heavy object is lifted to the top of the abandoned mine, it needs to be left still for a period of time. As the lifting system is used for a longer time, the wear and fatigue of the wire rope caused by friction and tension gradually increase. During the static process of the heavy object, once the wire rope is partially broken, it may cause serious safety accidents and limit the long-term stable operation of the system. Summary of the invention

[0003] An embodiment of the present application provides an automatic flipping and self-locking device for supporting heavy objects with gravity energy storage.

[0036] Specifically, in the above embodiment, the support platform 34 and the box body 31 are the main support components, and the support platform 34 and the box body 31 are respectively fixedly connected to the support platform connecting member 35 and the box body connecting member 32 by bolts 30; the first connecting rod 41 and the second connecting rod 42 are installed between the support platform connecting member 35 and the box body connecting member 32. The through holes on the first connecting rod 41 and the second connecting rod 42 are both installed with bearings 43, and the transmission shaft 51 and the radial shaft 45 are used to transmit power. The through holes on the first connecting rod 41 and the second connecting rod 42 and the through holes on the box body connecting member 32 are limited by sleeves 44, and the through holes on the first connecting rod 41, the second connecting rod 42 and the support platform connecting member 35 are sealed by end covers 46, and each end cover 46 is fixed to the first connecting rod 41, the second connecting rod 42 and the support platform connecting member 35 by 6 screws. The first connecting rod 41 and the second connecting rod 42 can make the support platform 34 flip 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 connecting member 32 is fixed to the box body 31 by means of the bolts 30; there is another through hole, in which a bearing 43 is installed, which is used to transmit the power brought by the transmission shaft 51; the box body connecting member 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, which are used to transmit 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 connecting member 35 on the box body 31, and the support platform connecting member 35 includes three bolt 30 holes and two through holes, in which bearings 43 are installed, which are used to transmit the power brought by the radial shaft 45, and the two through holes are sealed with end covers 46, and the end covers 46 are fixed to the support platform connecting member 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 supporting 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 and self-locks under the action of the reset spring 61. 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 lower surface of the support platform 34 and 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 is in contact and separated from the lower surface of the support platform 34, the support platform 34 is restored from the open state to the closed state and self-locked under the action of the spring restoring force, and the weight 2 can be placed on the support platform 34. When releasing energy, the weight 2 is first lifted by the lifting system 1 for a distance, 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 recovers from the open state to the closed state under the action of the spring restoring force. It should be noted that the gravity energy storage system uses two symmetrical support platforms 34 to achieve the distribution of the gravity of the weight 2, thereby ensuring the posture balance of the weight 2 in the static engineering.

[0042] The above are only preferred embodiments of the present application and are not intended to limit the present application. For those skilled in the art, the present application may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
