Description

Technical Field

[0001] The present invention relates to the technical field of new energy storage technology, and in particular to an energy storage device for new energy. Background Art

[0002] New energy generally refers to renewable energy that is developed and utilized based on new technologies, including solar energy, biomass energy, wind energy, geothermal energy, wave energy, ocean current energy and tidal energy, in addition to hydrogen energy. Coal, oil, natural gas, hydropower, nuclear fission energy and other energy sources that have been widely used are called conventional energy. New energy power generation is the process of generating electricity by using existing technologies and the above-mentioned new energy sources. In the process of generating electricity from new energy, energy storage equipment is needed to store the electricity. Most existing energy storage methods usually use lithium-ion batteries to store new energy. Lithium-ion batteries have the advantages of high energy density, long cycle life and low self-discharge rate, and are widely used in home energy storage, electric vehicles and other fields.

[0003] However, existing energy storage devices, such as lithium-ion batteries, often encounter bumps and shaking during use. When the battery is subjected to external mechanical damage such as puncture, extrusion, collision, etc., it is easy to damage the internal structure of the battery, causing direct contact between the positive and negative poles and short circuits, thereby causing safety problems. Therefore, we have proposed an energy storage device for new energy. Summary of the Invention

[0004] In order to solve the above technical problems, the present invention provides an energy storage device for new energy, comprising:

[0005] Lithium battery body;

[0006] Protective device: This device uses elastic material to wrap the lithium battery body to provide anti-collision protection, preventing the battery from being easily damaged by external mechanical damage such as puncture, extrusion, collision, etc., which may cause direct contact between the positive and negative electrodes and short circuit, thereby causing safety problems;

[0009] The anti-fall device stabilizes the lithium battery body by deploying diagonal braces in all directions to prevent the lithium battery body from falling directly when the bottom support surface of the lithium battery body shakes or tilts too much;

[0011] Wherein, the protective device includes:

[0012] The annular air cushion has an annular rubber body with an internal annular cavity. By placing an elastic annular air cushion on the outside of the lithium battery, it provides anti-collision protection to prevent the battery from being easily damaged by external mechanical damage such as puncture, extrusion, collision, etc., which may cause direct contact between the positive and negative electrodes and short circuit, thereby causing safety problems.

[0013] The annular air cushion is sleeved on the lithium battery body and fixedly connected to the lithium battery body, the inner wall of the annular air cushion is fixedly connected to one side of the auxiliary device, the outer surface of the annular air cushion is fixedly connected to one side of the cleaning device, and the bottom of the annular air cushion is fixedly connected to the top of the anti-fall device;

[0014] The inner wall of the annular air cushion is provided with a heat dissipation circular hole. By providing a plurality of heat dissipation circular holes on the inner wall of the annular air cushion, the lithium battery body is facilitated to dissipate heat to the outside, thereby preventing the annular air cushion from fully fitting and wrapping the outer surface of the lithium battery body, resulting in heat not being able to dissipate quickly. The outer surface of the annular air cushion is provided with an outward-opening circular hole, and the inner wall of the outward-opening circular hole is fixedly connected to a dust filter plate. The outer surface of the dust filter plate is provided with a dust filter circular hole. By arranging a dust filter plate with a plurality of dust filter circular holes on the surface in the outward-opening circular hole, particulate debris in the flowing air is filtered, thereby preventing external air from flowing into the annular air cushion multiple times and bringing in a large amount of particulate debris to affect the use of the internal components of the annular air cushion. The multiple dust filter circular holes with smaller apertures provided on the dust filter plate make the air flow rate passing through the outer wall of the annular air cushion faster, which is convenient for gas heat dissipation, thereby preventing the low heat dissipation efficiency when the high-temperature gas inside the annular air cushion gradually increases, resulting in difficulty in quickly cooling the lithium battery body;

[0015] There are multiple circular heat dissipation holes, and the multiple circular heat dissipation holes are respectively distributed on the inner wall of the annular air cushion; there are multiple outward-opening circular holes, and the multiple outward-opening circular holes are respectively distributed on the outer surface of the annular air cushion.

[0016] The spring is then pressed against the outside of the cylinder to release the force of the spring, which in turn pushes the outer wall of the cylinder to return to its original position and to provide protection for the cylinder. The cam is fixedly provided with a T-shaped groove on one side of the fixing plate, and one end of the fixing plate is fixedly connected to the inner wall of the annular air cushion, and the side of the annular sleeve is fixedly connected to the inner wall of the annular air cushion, and the side of the fixing plate is fixedly connected to the inner wall of the annular air cushion, and the side of the square rotating plate is away from the annular sleeve and is slidably connected to the inner wall of the T-shaped groove, and one end of the thin sliding rod is slidably connected to the inner wall of the T-shaped groove, and the square rotating plate is provided with a plurality of, and the plurality of square rotating plates are arranged on one side of the annular sleeve.

[0017] Furthermore, the cleaning device includes a concave scraper, which scrapes and cleans the surface of the filter plate when it gradually bends and stretches toward the filter plate, preventing a large amount of particulate debris from gradually accumulating on the surface of the dust filter holes after air circulates on the filter plate for a long time and affecting the gas flow. When the concave scraper gradually bends and stretches to a plane, it covers and protects the filter plate through the ventilation holes staggered between the surface and the dust filter holes, preventing the annular air cushion from being damaged by friction caused by particles and debris on the surface of the filter plate when it is impacted and squeezed. The outer surface of the concave scraper is fixedly connected to a curved brush, which rubs and cleans the filter holes on the surface of the filter plate when it moves, preventing a large amount of particulate debris from being stuck in the filter when it accumulates on the surface of the filter plate. The filter holes are blocked, and a ventilation hole is provided on the outer surface of the concave scraper. By providing a plurality of ventilation holes staggered with the dust filter holes on the concave scraper, the gas discharged from the dust filter holes is quickly discharged into the air, and the gas near the center of the filter plate is prevented from being covered by the concave scraper and difficult to be quickly discharged into the air and re-entering the annular air cushion. One side of the concave scraper is fixedly connected to the outer surface of the annular air cushion, and there are a plurality of concave scrapers, and the plurality of concave scrapers are distributed on the outer surface of the annular air cushion, and there are a plurality of arc-shaped brushes, and the plurality of arc-shaped brushes are evenly distributed on the outer surface of the concave scraper, and there are a plurality of ventilation holes, and the plurality of ventilation holes are evenly distributed on the outer surface of the concave scraper.

[0018] Furthermore, the anti-fall device includes a bottom square plate, the bottom of the bottom square plate is fixedly connected to a diagonal support plate, and a plurality of diagonal support plates are arranged around the bottom of the bottom square plate to carry out an expanded diagonal support to stabilize the lithium battery body, so as to prevent the lithium battery body from falling directly when the bottom supporting surface of the lithium battery body shakes or tilts too much. The outer surface of the diagonal support plate is sleeved and fixedly connected with a U-shaped frosted sleeve, and the friction of the bottom contact surface is increased by arranging a U-shaped frosted sleeve at the bottom of the diagonal support plate to prevent the device as a whole from offsetting and shaking when the bottom contact surface is relatively smooth. The bottom of the bottom square plate is fixedly connected to a rigid spring, and a rigid spring that is not easily compressed or stretched is arranged between the bottom long plate and the gravity chassis to stabilize the lithium battery body to prevent it from falling. When the spring with larger rigidity encounters shaking and impact, the lithium battery body on the top of the bottom long plate will perform multiple elastic reciprocating shakes, which can easily cause the internal structure to change. The bottom of the rigid spring is fixedly connected to the gravity chassis. By arranging a gravity chassis connected by a rigid spring at the bottom of the bottom long plate, the downward gravity of the entire equipment is increased to prevent the lithium battery body from shaking when encountering small shaking and impact. The top of the bottom square plate is fixedly connected to the bottom of the lithium battery body, and the bottom of the bottom square plate is fixedly connected to the bottom of the annular air cushion. There are multiple diagonal support plates, and the multiple diagonal support plates are respectively distributed around the bottom of the bottom square plate.

[0020] 1. The present invention provides anti-collision protection by arranging an annular air cushion made of elastic material on the outside of the lithium battery to prevent the internal structure of the battery from being easily damaged when the battery is subjected to external mechanical damage such as puncture, extrusion, collision, etc., resulting in direct contact and short circuit of the positive and negative poles and thus causing safety problems. When the annular air cushion loses the impact and extrusion, the extension spring pushes the outer wall of the annular air cushion outward to recover from the collision through the extension force, preventing the annular air cushion from being twisted and damaged after being impacted and extruded for a long time and being difficult to recover to the initial state for protection again. The concave scraper gradually bends and stretches toward the filter plate to scrape and clean the surface of the filter plate, preventing the surface of the filter plate from circling the dust filter holes for a long time after air circulates on the filter plate, thereby preventing a large amount of particulate debris from gradually accumulating on the surface of the dust filter holes and affecting the gas flow.

[0021] 2. The present invention provides a protective device by arranging an annular air cushion made of elastic material on the outside of the lithium battery to provide anti-collision protection, so as to prevent the internal structure of the battery from being easily damaged by external mechanical damage such as puncture, extrusion, collision, etc., resulting in direct contact and short circuit of the positive and negative poles, thereby causing safety problems; a plurality of heat dissipation circular holes are opened on the inner wall of the annular air cushion to facilitate the heat dissipation of the lithium battery body to the outside, and prevent the annular air cushion from fully fitting and wrapping the outer surface of the lithium battery body, so that heat cannot be quickly dissipated; a dust filter plate with a plurality of dust filter circular holes on the surface is provided in the external circular hole to filter particulate debris in the flowing air, and prevent the external air from flowing into the annular air cushion multiple times and bringing in a large amount of particulate debris that affects the use of the internal components of the annular air cushion; a plurality of dust filter circular holes with smaller apertures opened on the dust filter plate make the air flow rate passing through the outer wall of the annular air cushion faster, which is convenient for gas heat dissipation, and prevents the low heat dissipation efficiency when the high-temperature gas inside the annular air cushion gradually increases, making it difficult for the lithium battery body to cool down quickly.

[0022] When the annular air cushion loses the impact and extrusion, the extension spring pushes the outer wall of the annular air cushion outward for collision and recovery, thereby preventing the annular air cushion from being twisted and damaged after being impacted and extruded for a long time and being difficult to use.

[0023] The concave scraper is provided with a cleaning device, and the concave scraper is gradually bent and extended in the direction of the filter plate to scrape and clean the surface of the filter plate, so as to prevent a large amount of particles and debris from gradually accumulating on the surface of the dust filter holes after the air circulates on the filter plate for a long time and affecting the gas flow. The arc-shaped brush is moved to rub and clean the filter holes on the surface of the filter plate to prevent a part of the particles and debris accumulated on the surface of the filter plate from being stuck between the filter holes and causing blockage. When the concave scraper is gradually bent and extended to a flat shape, the filter plate is covered and protected by the ventilation holes arranged alternately with the surface and the dust filter holes, so as to prevent the particles and debris on the surface of the filter plate from being mixed between the impact surfaces and causing friction damage when the annular air cushion is impacted and squeezed. By providing a plurality of ventilation holes staggered with the dust filter holes on the concave scraper, the gas discharged from the dust filter holes is quickly discharged into the air, and the gas near the center of the filter plate is prevented from being affected by the covering of the concave scraper and being difficult to be quickly discharged into the air and then entering the annular air cushion again.

When the protective device 2 is impacted or squeezed, the internal auxiliary mechanism will limit it to avoid distortion and deformation, and push the protective device 2 to return to its initial state when it is not impacted or squeezed. At the same time, the cleaning device 4 arranged on the outer surface of the protective device 2 scrapes and cleans the surface of the air outlet of the protective device 2 when it is impacted or squeezed. Anti-collision protection is provided by sheathing an annular air cushion 201 made of elastic material on the outside of the lithium battery. A plurality of heat dissipation circular holes 202 are provided on the inner wall of the annular air cushion 201 to facilitate the heat dissipation of the lithium battery body 1 to the outside. When the annular air cushion 201 is impacted or squeezed, it is compressed inwards. At this time, the heat inside the annular air cushion 201 is dissipated through the heat dissipation circular holes 202. The dust will pass through the dust filter holes 205 of the dust filter plate 204 and be discharged outwards quickly.

By arranging three fixing plates 305 on the periphery of the extension spring 301 to limit the inclined sliding square rotating plate 303, and then fixing the extension spring 301 through the annular sleeve 302, when the square rotating plate 303 slides, it drives the penetrating thin sliding rod 304 to slide on the inner wall of the T-shaped slide groove 306 together, and by setting the penetrating thin sliding rod 304 of the direction rotating plate to slide in the T-shaped slide groove 306, the inclined sliding square rotating plate 303 is adjusted. The sliding limit is achieved by setting the length of the annular sleeve 302 to be greater than the length of the extension spring 301 after it is fully compressed, so that the extension spring 301 can be stored. When the annular air cushion 201 loses the impact and extrusion, the extension spring 301 pushes the outer wall of the annular air cushion 201 to the outside to collide and recover through the extension force. The concave scraper 401 is set on the outer surface of the annular air cushion 201 and gradually stretches from a concave shape to a flat shape in the direction of the filter plate when it is impacted and extruded, and the inner side fits the surface of the annular air cushion 201. The concave scraper 401 gradually bends and stretches in the direction of the filter plate to scrape and clean the surface of the filter plate. When the concave scraper 401 bends and stretches, it drives the arc-shaped brush 402 on the outer surface to move together. When the arc-shaped brush 402 moves, it rubs and cleans the filter holes on the surface of the filter plate.When the concave scraper 401 gradually bends and stretches to a flat shape, the filter plate is covered and protected by the ventilation holes 403 arranged on the surface and staggered with the dust filter holes 205. By providing multiple ventilation holes 403 staggered with the dust filter holes 205 on the concave scraper 401, the gas exhausted from the dust filter holes 205 can be quickly discharged into the air. By providing multiple diagonal support plates 502 around the bottom of the bottom square plate 501, the lithium battery body 1 is supported and stabilized in an expandable diagonal manner. A U-shaped frosted sleeve 503 is sleeved on the bottom of the diagonal support plate 502 to increase the friction of the bottom contact surface. A gravity base 505 connected by a rigid spring 504 is provided at the bottom of the bottom square plate 501 to increase the downward gravity of the entire device. A rigid spring 504 that is not easily compressed or stretched is provided between the bottom square plate 501 and the gravity base 505 to stabilize the lithium battery body 1.
