Technical Field
[0001] This utility model relates to the field of gravity energy storage technology, and in particular to a wire rope lubrication mechanism for gravity energy storage. Background Technology
[0002] Gravity energy storage is a novel technology that converts electrical energy during off-peak hours into mechanical potential energy for storage, and releases it as electrical energy during peak hours. Gravity energy storage effectively distributes electricity across different time periods, ensuring stable power supply. A typical gravity energy storage device consists of a weight, a storage well, pulley systems, and steel cables. The steel cables pull the pulley systems, causing the weight inside the storage well to rise and fall, thus storing and releasing mechanical potential energy. The number of storage wells connected by a single steel cable is inversely proportional to the system's energy storage efficiency. Theoretically, connecting one storage well with a single steel cable yields the highest energy storage efficiency. However, increasing the number of storage wells and steel cables increases the number of supporting equipment and the floor space required, leading to higher costs, lower cost-effectiveness, and reduced economic benefits. Therefore, gravity energy storage systems are primarily in the experimental stage in the early stages, requiring the comparison of economic benefits by connecting different numbers of storage wells with steel cables.
[0003] To reduce the friction between the wire rope and the pulley system and lower the resistance during the lifting of heavy objects, lubrication is required. Traditional lubrication mechanisms are mostly matched with and installed at the winch. The wire ropes at the end of the series of energy storage wells cannot be fully wound onto the winch, so a considerable length of wire rope cannot be lubricated by the lubrication mechanism and can only be lubricated manually. However, manual lubrication is time-consuming, labor-intensive, and inefficient.
[0004] Therefore, it is necessary to propose a wire rope lubrication mechanism for gravity energy storage to improve the lubrication efficiency of the end wire rope. Utility Model Content
[0005] The purpose of this invention is to solve the problem that existing lubrication devices cannot lubricate the end of the wire rope and can only use manual lubrication, resulting in low lubrication efficiency of the wire rope. A wire rope lubrication mechanism for gravity energy storage is provided.
[0006] The technical solution of this utility model is:
[0007] A wire rope lubrication mechanism for gravity energy storage includes a housing and a support frame. The housing has through holes at both ends and an oil pump. An oiling ring, an oil tank, and an oil collection groove are fixedly connected inside the housing. The oiling ring is provided with oiling cotton, and an oiling hole is opened in the middle of the oiling cotton along its axial direction. The oiling ring is provided with an oil seepage pipe that communicates with the oil tank, and the oil seepage pipe guides the oil in the oil tank to the oiling cotton.
[0008] The oil collection trough is located at the bottom of the oiling ring. The top of the oil collection trough is open and a filter cotton is installed at the opening. The oil pump is connected to both the oil collection trough and the oil tank.
[0009] Furthermore, both ends of the housing are equipped with descaling devices, which include a drive unit and two opposing claws. The drive unit drives the claws to move closer or further apart.
[0010] Furthermore, the driving device is a cylinder, with each claw corresponding to a cylinder, and the claw is fixedly connected to the output shaft of the cylinder.
[0011] Furthermore, the jaws are semi-circular, and when two opposing jaws approach each other, they can form a circle coaxial with the through hole.
[0012] Furthermore, the claws are fixedly connected with descaling cotton.
[0013] Furthermore, a level sensor is installed in the oil collection tank, and the level sensor is connected to a controller, which controls the start and stop of the oil pump and drive device.
[0014] Furthermore, a cover plate is threadedly connected to the through hole, with a handle on the outside of the cover plate and a rope hole coaxial with the through hole in the middle of the cover plate.
[0015] This utility model discloses a wire rope lubrication mechanism for gravity energy storage. A support frame provides support and fixation for the casing. The device is placed at the wellhead of the last well in a series of energy storage wells. An oiling ring delivers oil from the oil tank to the oiling cotton. The wire rope passes through the oiling hole. When the wire rope is wound or released, the oiling cotton applies lubricating oil, thus completing the lubrication. Since the wire rope may drip oil after oiling, an oil collection groove is installed at the bottom of the oiling ring to collect the lubricating oil. A filter cotton filters the dripping oil, and the clean lubricating oil enters the oil collection groove and is then returned to the oil tank for reuse by an oil pump. Compared with traditional technologies, this solution does not require a winch and can operate independently to lubricate the wire rope. It can be placed anywhere on the wire rope for convenient lubrication at any point, improving lubrication flexibility, replacing manual lubrication, and increasing lubrication efficiency.

Detailed Implementation
[0022] To make the technical means, technical features, utility model purpose and technical effects of this utility model easier to understand, the present utility model will be further described below with reference to specific illustrations.
[0023] Example 1:
[0024] like Figure 1 and Figure 4 As shown, this embodiment provides a wire rope lubrication mechanism for gravity energy storage, including a housing 1 and a support frame 2. The housing 1 and the support frame 2 are fixedly connected by screws. Through holes 3 are provided at both ends of the housing 1. It also includes an oil pump 4. An oiling ring 5, an oil tank 6, and an oil collection groove 7 are fixedly connected by screws inside the housing 1. Figure 5 As shown, an oiling cotton 8 is fixedly connected to the oiling ring 5 by screws. An oiling hole 9 is opened in the middle of the oiling cotton 8 along its axial direction. The oiling ring 5 is provided with an oil seepage pipe 10 that communicates with the oil tank 6. The oil seepage pipe 10 is located inside the oiling ring 5 and guides the oil in the oil tank 6 to the oiling cotton 8. The oil collection trough 7 is located at the bottom of the oiling ring 5. The top of the oil collection trough 7 is open and a filter cotton 11 is fixedly connected to the opening by screws. The oil pump 4 is connected to the oil collection trough 7 and the oil tank 6 respectively. The oiling cotton 8 can increase the contact area with the wire rope and improve the oiling effect. Preferably, four oil seepage pipes 10 are provided on the oiling ring 5 and are evenly distributed along the axis of the oiling ring 5.
[0025] Preferably, both ends of the housing 1 are provided with descaling devices 12. Each descaling device 12 includes a drive device 13 and two opposing claws 14. The drive device 13 drives the claws 14 to move closer or further apart. Preferably, the drive device 13 is a cylinder, and each claw 14 corresponds to one cylinder. The claws 14 are screwed to the output shaft of the cylinder. Preferably, the claws 14 are semi-circular, and when the two opposing claws 14 move closer together, they can form a circle coaxial with the through hole 3. The cylinder is fixed inside the housing 1 by screws. Preferably, descaling cotton 15 is screwed to the claws 14. Since the wire rope is exposed to the outside, dust and dirt will accumulate on the rope surface. When the cylinder drives the claws 14 to move closer together, the two opposing claws 14 can engage with the wire rope... The surface is adhered, thus achieving the effect of scraping off dust and dirt. Preferably, the descaling devices 12 at both ends of the housing 1 operate alternately. When the wire rope is wound, the wire rope enters from one end of the housing 1, and the descaling device 12 at that end drives the claws 14 to move closer together to scrape off dirt. The descaling device 12 at the other end does not work, and drives the claws 14 to move away from each other, so that the claws 14 do not contact the wire rope and avoid scraping off the freshly applied lubricating oil. When the wire rope is released, the wire rope moves in the opposite direction. The descaling device 12 that previously drove the claws 14 to move closer together now drives the claws 14 to move away from each other, thus stopping the scraping action. The descaling device 12 that previously drove the claws 14 to move away from each other now drives the claws 14 to move closer together and begins to scrape off dirt from the wire rope.
[0026] Preferred, such as Figure 4 As shown, a liquid level sensor 16 is fixedly connected to the oil collection tank 7 with screws. The liquid level sensor 16 is connected to a controller, which controls the start and stop of the oil pump 4 and the drive device 13. The sensor can also monitor the oil level in the oil collection tank 7 at all times and send an electrical signal to the controller. The controller controls the start and stop of the oil pump 4 according to the electrical signal. Preferably, a displacement sensor is installed in the housing 1 with screws, which can monitor the movement direction of the wire rope. According to the movement direction of the wire rope, it sends different electrical signals to the controller. The controller controls which end of the housing 1 to perform the scraping action and which end of the descaling device 12 to stop the scraping action according to the electrical signal of the displacement sensor. Since the controller is a relatively mature technology, those skilled in the art can purchase a suitable controller model on the market. Regarding the selection of the controller and the specific installation method, those skilled in the art can install it themselves according to the accompanying instruction manual. It will not be described in detail here.
[0027] Preferred, such as Figure 2 and Figure 3As shown, a cover plate 17 is threadedly connected to the through hole 3. A handle 18 is provided on the outer side of the cover plate 17. A rope hole 19 coaxial with the through hole 3 is provided in the middle of the cover plate 17. The steel wire rope passes through the housing through the rope hole and enters the oiling hole. By removing the cover plate 17, it is convenient to replace the descaling cotton 15. By installing the cover plate 17, it can effectively prevent external dust and dirt from entering the housing 1 through the through hole 3.
[0028] In use, the support frame 2 can be used to provide support and fixation for the housing 1. The device is placed at the wellhead of the end of the series-connected energy storage wells. The oiling ring 5 delivers oil from the oil tank 6 to the oiling cotton 8. The wire rope passes through the oiling hole 9. When the wire rope is wound or released, the oiling cotton 8 applies lubricating oil to the wire rope, thus completing the lubrication of the wire rope. Since the wire rope will drip oil after oiling, an oil collection groove 7 is set at the bottom of the oiling ring 5 to collect the lubricating oil. The filter cotton 11 can filter the dripping oil. The clean lubricating oil enters the oil collection groove 7 and returns to the oil tank 6 for use under the action of the oil pump 4. Compared with traditional technology, this technical solution does not need to be matched with a winch and can work independently to lubricate the wire rope. It can be placed at any point on the wire rope for convenient lubrication at any position, improving the flexibility of lubrication, replacing manual lubrication, and improving lubrication efficiency.
[0029] The above description is merely a preferred embodiment of this utility model and is not intended to limit the scope of this utility model. All equivalent changes and modifications made in accordance with the scope of the claims of this utility model should fall within the technical scope of this utility model.
