It is widely used in computers, automobiles and home appliances.

[0003] The patent with the patent announcement number CN216793867U discloses a lithium battery energy storage device with stable heat dissipation, which relates to the field of lithium battery technology, including a lithium battery energy storage mechanism and a water-cooled heat dissipation mechanism connected to the middle of the two sides of the lithium battery energy storage mechanism; the lithium battery energy storage mechanism includes a lithium battery body, a nameplate connected to the middle of the lithium battery body, and an isolation seat connected to the middle of the bottom end face of the lithium battery body; and also includes a waterproof mechanism: the waterproof mechanism includes a hydraulic cylinder connected to the middle of the bottom end of the lithium battery body, a support block connected to the output end of the bottom of the hydraulic cylinder, and a water immersion sensor connected to the middle of the support block on one side of the isolation seat. The patent solves the problem that the internal heat dissipation of the existing lithium battery energy storage device is generally achieved by relying on a built-in heat dissipation fan, which has high cost and occupies its internal space, resulting in insufficient energy storage. At the same time, when a flood occurs suddenly, it is easy to be flooded.

[0004] However, the current lithium battery energy storage device has the following problems: the lithium battery will generate a large amount of heat when the lithium battery energy storage device is in use, and the heat generated by the lithium battery located at the bottom of the lithium battery energy storage device is difficult to be attracted by the cooling fan and discharged from the lithium battery energy storage device, which will cause heat accumulation inside the lithium battery energy storage device and lead to overheating and damage of the lithium battery. Therefore, we propose a multi-module thermal conductivity lithium battery energy storage device. Summary of the invention

[0005] In view of the deficiencies in the prior art, the present invention provides a multi-module thermal conductivity lithium battery energy storage device, which solves the problems raised in the above background technology.

[0006] To achieve the above objectives, the present invention is implemented through the following technical solutions: a multi-module thermal conductivity lithium battery energy storage device, comprising a device body, a battery module is fixed inside the device body, and the battery module is composed of two brackets and a plurality of batteries, and the plurality of batteries are evenly and equidistantly fixed between the two brackets, a mounting cover is fixed on the top of the device body by bolts, a mesh shell is fixed on the top of the mounting cover, a cross frame is fixed inside the mesh shell, a cooling fan is arranged at the bottom of the cross frame, an L-shaped column is fixed at the bottom of the rotating shaft of the cooling fan, a groove plate is slidably installed inside the device body, and one end of the L-shaped column away from the rotating shaft of the cooling fan is slidably installed inside the groove plate, a fixing frame is fixed inside the device body, and the fixing frame is located below the groove plate, a fixing cylinder is evenly and equidistantly fixed on the bottom of the fixing frame, and a plurality of fixing cylinders are respectively located between the batteries of the battery module, and the bottom of the fixing frame is evenly and equidistantly rotatably installed The one-way bearing for limiting the one-way rotation of the rotating rod is arranged between the rotating rod and the fixed frame, a spiral blade is fixed on the lower outside of the rotating rod, a friction ring is fixed on the top of the rotating rod, and a plurality of friction plates are fixed on the bottom of the groove plate at uniform and equidistant intervals, the friction plate is located on the right side of the friction ring, and the friction plate contacts the outer wall of the friction ring, the rotating shaft of the cooling fan drives the L-shaped column rod to rotate, one end of the L-shaped column rod slides along the inside of the groove plate and makes a circular motion, the L-shaped column rod pushes the groove plate to slide back and forth inside the device body, and the groove plate drives the friction plate to move with it, when the friction plate moves forward, under the action of the friction force between the friction plate and the friction ring, the friction plate pushes the friction ring to rotate, the friction ring drives the rotating rod to rotate, the rotating rod drives the spiral blade to rotate, and the spiral blade transmits the heat generated by the lithium battery below the inside of the device body upward through the fixed cylinder, when the friction plate moves backward, the one-way bearing between the rotating rod and the fixed frame limits the rotation of the rotating rod, so the rotating rod will not drive the spiral blade to rotate.

[0007] According to the above technical solution, an L-shaped rod is fixed to the top front side and the top rear side of several friction plates, and two inclined plates are fixed to the bottom left side of the L-shaped rod, and the two inclined plates are distributed in an eight-shaped shape. At the same time, when the friction plate moves back and forth, the friction plate drives the L-shaped rod to move back and forth, and the L-shaped rod drives the inclined plate to move with it. The eight-shaped inclined plate will fan the heat at the bottom of the internal body of the device to the fixed cylinder.

[0008] According to the above technical solution, a heat-conducting device for promoting rapid heat dissipation of the batteries of the battery module is arranged on the front and rear sides of the device body, and the heat-conducting device includes two fixed plates and a plurality of heat-conducting rods, the two fixed plates are respectively fixed on the top front side and the top rear side of the friction plate, a plurality of heat-conducting rods are evenly and equidistantly fixed on the bottom of the two fixed plates, and a plurality of heat-conducting rods are respectively in contact with the outer wall of the batteries of the battery module, and when the friction plate moves back and forth, the friction plate drives the fixed plate to move back and forth, and the fixed plate drives the heat-conducting rods to move on the battery surface of the battery module.

[0009] According to the above technical solution, the heat-conducting device also includes a plurality of folding capsules, two air cavity plates, four one-way air inlet nozzles, and a plurality of one-way air outlet nozzles. The two air cavity plates are respectively fixed to the front side and the rear side of the inner wall of the device body. One end of a plurality of the folding capsules is fixed to the side away from each other of the two fixed plates. The other ends of a plurality of the folding capsules are respectively fixed to the side close to each other of the two air cavity plates. The four one-way air inlet nozzles are respectively fixed to the left and right sides of the two air cavity plates, and the four one-way air inlet nozzles penetrate the inner wall of the device body. One end of a plurality of the one-way air outlet nozzles is evenly and equidistantly fixed to the bottom of the two air cavity plates. The other ends of several of the one-way air outlet nozzles extend to the lower interior of the device body, the one-way air outlet nozzle is used to control the one-way air outlet of the folding bag, and the one-way air inlet nozzle is used to control the one-way air inlet of the folding bag. When the friction plate drives the fixed plate to move forward, the fixed plate on one side squeezes the folding bag on the front side, and the fixed plate on the other side stretches the folding bag on the rear side. When the folding bag is squeezed, the air in the folding bag is transmitted to the one-way air outlet nozzle through the air cavity plate and sprayed out. The air sprayed from the one-way air outlet nozzle will be injected into the lower interior of the device body. When the folding bag is stretched, the one-way air inlet nozzle will absorb outside air and transmit it to the folding bag through the air cavity plate.

[0010] According to the above technical scheme, an anti-corrosion device for preventing external moisture from invading the device body is provided at the outer wall of the device body, and the anti-corrosion device includes two long boxes, two air ports, and a plurality of dehumidification blocks. The two long boxes are respectively fixed on the left and right sides of the device body, and the long boxes are located at the one-way air inlet nozzle. The two air ports are respectively opened in the middle of the two long boxes. A plurality of dehumidification blocks are evenly and equidistantly fixed on the left and right sides of the inner walls of the two long boxes, and a plurality of dehumidification blocks are staggered. In the process of the one-way air inlet nozzle absorbing external air, the external air will first enter the long box through the air port before it can be absorbed by the one-way air inlet nozzle. In this process, the external air will pass through the dehumidification blocks, and the dehumidification blocks will absorb the moisture contained in the external air. At the same time, since the dehumidification blocks are staggered, the distance of the external air flowing through the long box to the one-way air inlet nozzle is increased.

[0011] According to the above technical solution, the anti-corrosion device also includes a positioning rod, a wavy scraper, a contact plate, and two round blocks. The positioning rod passes through and is slidably installed on the outer wall of the long box on one side away from the device body, and a spring is provided between the positioning rod and the outer wall of the long box.

The contact plate is fixed to one side of the wavy scraper close to the device body, and the contact plate passes through the outer wall of the device body. The two round blocks are respectively fixed to the bottom of the strip groove plate. On the left and right sides, the end of the resistance plate away from the wavy scraper is semicircular, and the semicircular shape of the resistance plate is located on the movement trajectory of the semicircular surface of the round block. A through hole matching the air port is opened in the middle of the wavy scraper. At the same time, when the groove plate moves back and forth, the groove plate drives the round block to move with it, and the round surface of the round block pushes the semicircular shape of the resistance plate to drive the wavy scraper toward the inner wall of the long box. When the round surface of the round block does not push the semicircular part of the resistance plate, under the action of the spring force corresponding to the positioning rod, the positioning rod pushes the wavy scraper to reset and move.

[0012] The present invention provides a multi-module thermal conductivity lithium battery energy storage device. It has the following beneficial effects:

[0013] (1) The present invention uses a heat dissipation fan, an L-shaped column rod, a groove plate, a device body, a friction plate, a friction ring, and a rotating rod to drive the spiral blades to transport the heat generated by the lithium battery at the bottom of the device body upward through the fixed cylinder, thereby avoiding the problem that the heat generated by the lithium battery at the bottom of the device body is difficult to be attracted by the heat dissipation fan and discharged from the device body, thereby causing heat accumulation inside the device body and causing overheating and damage to the lithium battery. At the same time, the one-way bearing between the rotating rod and the fixed frame will limit the rotation of the rotating rod, thereby avoiding the problem that the rotating rod drives the spiral blades to rotate in the opposite direction, causing the spiral blades to transport the heat to the bottom of the device body and causing heat accumulation. At the same time, the friction plate and the L-shaped rod cooperate to drive the eight-shaped inclined plate to fan the heat at the bottom of the device body toward the fixed cylinder, thereby facilitating the fixed cylinder to discharge the heat from the bottom of the device body.

[0014] (2) The present invention arranges a heat-conducting device so that the friction plate and the fixed plate cooperate to drive the heat-conducting rod to move on the battery surface of the battery module. The movement of the heat-conducting rod drives the air around the battery surface to increase the cooling effect of the battery surface, which helps to reduce the battery temperature and improve the safety and stability of the battery. The friction plate, the fixed plate, the folding bag and the air cavity plate cooperate to drive the one-way air outlet nozzle to spray air to the lower part of the device body. The injected air can promote ventilation inside the device body, help to remove the heat and harmful gases generated by the battery, reduce the battery temperature and improve the safety and stability of the battery.

[0015] (3) The present invention arranges an anti-corrosion device so that the one-way air inlet nozzle, the air port and the long box cooperate to drive the dehumidification block to absorb moisture contained in the outside air, thereby avoiding the problem that moisture contained in the outside air is sucked into the device body by the one-way air inlet nozzle, causing the battery module to be corroded by moisture and damaged. At the same time, since the dehumidification blocks are arranged in a staggered manner, the distance of the outside air flowing through the long box to the one-way air inlet nozzle is increased, thereby increasing the contact area between the outside air and the dehumidification block, and improving the dehumidification effect of the dehumidification block on the outside air; at the same time, the grooved plate, the round block and the contact plate cooperate to drive the wavy scraper to scrape the surface of the dehumidification block. Scraping the surface of the dehumidification block can drive the surrounding air to flow, promote the exchange between humid air and the dehumidification block, and accelerate the speed of moisture adsorption.

DETAILED DESCRIPTION

[0024] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0025] See also Figure 1-Figure 7 One embodiment of the present invention is: a multi-module thermal conductive lithium battery energy storage device, comprising a device body 1, a battery module 6 is fixed inside the device body 1, and the battery module 6 is composed of two brackets and a plurality of batteries, and the plurality of batteries are evenly and equidistantly fixed between the two brackets, a mounting cover 2 is fixed on the top of the device body 1 by bolts, a mesh shell 3 is fixed on the top of the mounting cover 2, a cross frame 4 is fixed inside the mesh shell 3, a cooling fan 5 is arranged at the bottom of the cross frame 4, and a rotating shaft of the cooling fan 5 is fixed at the bottom. The device body 1 is provided with an L-shaped column 9, a slot plate 10 is slidably installed inside the device body 1, and one end of the L-shaped column 9 away from the rotating shaft of the cooling fan 5 is slidably installed inside the slot plate 10, and a fixing frame 12 is fixed inside the device body 1, and the fixing frame 12 is located below the slot plate 10, and a fixing cylinder 14 is evenly and equidistantly fixed at the bottom of the fixing frame 12, and a plurality of fixing cylinders 14 are respectively located between the batteries of the battery module 6, and a rotating rod 15 is evenly and equidistantly installed at the bottom of the fixing frame 12, and the rotating rod 15 and the fixing frame 12 are connected. A one-way bearing is provided between the rotating rod 15 for limiting the one-way rotation of the rotating rod 15, a spiral blade 16 is fixed on the lower outside of the rotating rod 15, a friction ring 13 is fixed on the top of the rotating rod 15, and a plurality of friction plates 11 are evenly and equidistantly fixed on the bottom of the groove plate 10, the friction plate 11 is located on the right side of the friction ring 13, and the friction plate 11 is in contact with the outer wall of the friction ring 13. Through the arrangement of the above structure, the spiral blade 16 transmits the heat generated by the lithium battery at the lower part of the device body 1 upward through the fixed cylinder 14, thereby avoiding the heat generated by the lithium battery at the lower part of the device body 1 being difficult to be attracted by the cooling fan 5 to be discharged from the device body 1, thereby causing the heat accumulation inside the device body 1, resulting in the problem of overheating and damage of the lithium battery. Through the arrangement of the above structure, when the friction plate 11 moves backward, the one-way bearing between the rotating rod 15 and the fixed frame 12 will limit the rotation of the rotating rod 15, so that the rotating rod 15 will not drive the spiral blade 16 to rotate, thereby avoiding the spiral blade 16 from rotating in the opposite direction, resulting in the spiral blade 16 transmitting the heat to the lower part of the device body 1, resulting in the problem of heat accumulation.

[0026] An L-shaped rod 17 is fixed to the top front side and the top rear side of the plurality of friction plates 11, and two inclined plates 18 are fixed to the bottom left side of the L-shaped rod 17, and the two inclined plates 18 are distributed in an eight-shaped shape. Through the arrangement of the above structure, the inclined plates 18 in an eight-shaped shape will fan the heat at the lower part of the inside of the device body 1 to the fixed cylinder 14, thereby facilitating the fixed cylinder 14 to discharge the heat from the lower part of the inside of the device body 1.

[0027] During use, when the battery module 6 is in use, the battery module 6 generates heat, and the cooling fan 5 is started. The cooling fan 5 will blow the heat generated by the battery module 6 inside the device body 1 outward. During the rotation of the cooling fan 5, the rotating shaft of the cooling fan 5 drives the L-shaped column rod 9 to rotate. The end of the L-shaped column rod 9 away from the rotating shaft of the cooling fan 5 slides along the inside of the slot plate 10 and makes a circular motion. The end of the L-shaped column rod 9 away from the rotating shaft of the cooling fan 5 pushes the slot plate 10 to slide back and forth inside the device body 1, and the slot plate 10 drives the friction plate 11 to move with it. When the friction plate 11 moves forward, under the action of the friction force between the friction plate 11 and the friction ring 13, the friction plate 11 pushes the friction ring 13 to rotate, and the friction ring 13 drives the rotating rod 15 to rotate, and the rotating rod 15 drives the spiral blade 16 to rotate. The spiral blade 16 dissipates the heat generated by the lithium battery at the bottom of the device body 1 through the solid The fixed cylinder 14 transports heat upward, thereby preventing the heat generated by the lithium battery at the bottom of the device body 1 from being difficult to be attracted by the cooling fan 5 and discharged from the device body 1, thereby causing heat accumulation inside the device body 1 and leading to the problem of overheating and damage of the lithium battery. When the friction plate 11 moves backward, the one-way bearing between the rotating rod 15 and the fixing frame 12 will limit the rotation of the rotating rod 15, so the rotating rod 15 will not drive the spiral blade 16 to rotate, thereby preventing the spiral blade 16 from rotating in the opposite direction, causing the spiral blade 16 to transport heat to the bottom of the device body 1, leading to the problem of heat accumulation; at the same time, when the friction plate 11 moves back and forth, the friction plate 11 drives the L-shaped rod 17 to move back and forth, and the L-shaped rod 17 drives the inclined plate 18 to move with it. The inclined plate 18 in the shape of an eight will fan the heat at the bottom of the inside of the device body 1 to the fixed cylinder 14, thereby facilitating the fixed cylinder 14 to discharge the heat from the bottom of the inside of the device body 1.

[0028] See also Figure 1-Figure 7 On the basis of the above embodiment, in another embodiment of the present invention, a heat conducting device 7 for promoting rapid heat dissipation of the battery module 6 is provided on the front and rear sides of the device body 1 .

[0029] The heat-conducting device 7 includes two fixed plates 71 and a plurality of heat-conducting rods 72. The two fixed plates 71 are respectively fixed on the top front side and the top rear side of the friction plate 11. The plurality of heat-conducting rods 72 are evenly and equidistantly fixed on the bottom of the two fixed plates 71, and the plurality of heat-conducting rods 72 are respectively in contact with the outer wall of the battery of the battery module 6. Through the arrangement of the above structure, the fixed plates 71 drive the heat-conducting rods 72 to move on the battery surface of the battery module 6. The movement of the heat-conducting rods 72 will drive the air flow around the battery surface, thereby increasing the cooling effect of the battery surface, helping to reduce the battery temperature, and improving the safety and stability of the battery.

[0030] The heat conducting device 7 further includes a plurality of folding capsules 73, two air cavity plates 74, four one-way air inlet nozzles 75, and a plurality of one-way air outlet nozzles 76. The two air cavity plates 74 are respectively fixed to the front side and the rear side of the inner wall of the device body 1. One end of the plurality of folding capsules 73 is fixed to the side away from each other of the two fixing plates 71, and the other ends of the plurality of folding capsules 73 are respectively fixed to the side close to each other of the two air cavity plates 74. The four one-way air inlet nozzles 75 are respectively fixed to the left and right sides of the two air cavity plates 74, and the four one-way air inlet nozzles 75 penetrate the inner wall of the device body 1. One end of the plurality of one-way air outlet nozzles 76 is evenly and equidistantly fixed to the bottom of the two air cavity plates 74. The other end of the nozzle 76 extends to the lower part of the interior of the device body 1. The one-way air outlet nozzle 76 is used to control the one-way air outlet of the folding bag 73, and the one-way air inlet nozzle 75 is used to control the one-way air inlet of the folding bag 73. Through the arrangement of the above-mentioned structure, the air ejected from the one-way air outlet nozzle 76 will be injected into the lower part of the interior of the device body 1. The injected air can promote ventilation inside the device body 1, help to remove the heat and harmful gases generated by the battery, reduce the battery temperature, and improve the safety and stability of the battery. When the folding bag 73 is stretched, the one-way air inlet nozzle 75 will absorb external air and transmit it to the folding bag 73 through the air cavity plate 74, thereby achieving the purpose of replenishing the air in the folding bag 73.

[0031] The outer wall of the device body 1 is provided with an anti-corrosion device 8 for preventing external moisture from invading the device body 1. The anti-corrosion device 8 includes two long boxes 81, two air ports 811, and a plurality of dehumidification blocks 82. The two long boxes 81 are respectively fixed on the left and right sides of the device body 1, and the long boxes 81 are located at the one-way air inlet nozzle 75. The two air ports 811 are respectively opened in the middle of the two long boxes 81. The plurality of dehumidification blocks 82 are evenly and equidistantly fixed on the left and right sides of the inner walls of the two long boxes 81, and the plurality of dehumidification blocks 82 are staggered. Through the arrangement of the above structure, the dehumidification block 82 absorbs the moisture contained in the outside air, thereby avoiding the problem that the moisture contained in the outside air is sucked into the device body 1 by the one-way air inlet nozzle 75, causing the battery module 6 to be corroded by moisture and damaged. At the same time, since the dehumidification blocks 82 are staggered, the distance of the outside air flowing through the long box 81 to the one-way air inlet nozzle 75 is increased, thereby increasing the contact area between the outside air and the dehumidification block 82, and improving the dehumidification effect of the dehumidification block 82 on the outside air.

[0032] The anti-corrosion device 8 also includes a positioning rod 83, a wavy scraper 84, a contact plate 85, and two round blocks 86. The positioning rod 83 penetrates and is slidably installed on the outer wall of the long box 81 away from the device body 1, and a spring is provided between the positioning rod 83 and the outer wall of the long box 81. The wavy scraper 84 is fixed to one end of the positioning rod 83 close to the device body 1, and the wavy scraper 84 contacts the outer wall of the dehumidification block 82. The contact plate 85 is fixed to the side of the wavy scraper 84 close to the device body 1, and the contact plate 85 penetrates the outer wall of the device body 1. The two round blocks 86 are provided on the outer wall of the dehumidification block 82. The round blocks 86 are respectively fixed on the left and right sides of the bottom of the groove plate 10, and the end of the resistance plate 85 away from the wavy scraper 84 is semicircular. The semicircular shape of the resistance plate 85 is located on the semicircular movement trajectory of the round block 86. The middle part of the wavy scraper 84 is provided with a through hole matching the air port 811. Through the setting of the above structure, the wavy scraper 84 scrapes the surface of the dehumidification block 82. Scraping the surface of the dehumidification block 82 can drive the surrounding air flow, promote the exchange between humid air and the dehumidification block 82, and accelerate the speed of moisture adsorption.

[0033] When in use, when the friction plate 11 moves back and forth, the friction plate 11 drives the fixed plate 71 to move back and forth, and the fixed plate 71 drives the heat-conducting rod 72 to move on the battery surface of the battery module 6. The movement of the heat-conducting rod 72 drives the air around the battery surface to flow, thereby increasing the cooling effect of the battery surface, helping to reduce the battery temperature, and improving the safety and stability of the battery. When the friction plate 11 drives the fixed plate 71 to move forward, the fixed plate 71 on one side squeezes the folding bag 73 on the front side, and the fixed plate 71 on the other side stretches the folding bag 73 on the rear side. When the folding bag 73 is squeezed, the air in the folding bag 73 is transmitted to the one-way air outlet nozzle 76 through the air cavity plate 74 and is ejected. The air ejected from the one-way air outlet nozzle 76 will be injected into the lower part of the device body 1. The injected air can promote ventilation inside the device body 1, help to remove the heat and harmful gases generated by the battery, reduce the battery temperature, and improve the safety and stability of the battery. When the folding bag 73 is stretched, the one-way air inlet nozzle 75 will absorb external air and transmit it to the folding bag 73 through the air cavity plate 74, thereby achieving the purpose of replenishing the air in the folding bag 73.

[0034] When the one-way air inlet nozzle 75 absorbs the outside air, the outside air will first enter the long box 81 through the air port 811 before being absorbed by the one-way air inlet nozzle 75. In this process, the outside air will pass through the dehumidification block 82, and the dehumidification block 82 will absorb the moisture contained in the outside air, thereby avoiding the problem that the moisture contained in the outside air is sucked into the device body 1 by the one-way air inlet nozzle 75, causing the battery module 6 to be corroded by moisture and damaged. At the same time, since the dehumidification blocks 82 are staggered, the distance of the outside air flowing through the long box 81 to the one-way air inlet nozzle 75 is increased, thereby increasing the contact area between the outside air and the dehumidification block 82, thereby improving The dehumidification block 82 has a dehumidifying effect on the external air; at the same time, when the groove plate 10 moves back and forth, the groove plate 10 drives the round block 86 to move with it, and the round surface of the round block 86 pushes the semicircular shape of the contact plate 85 to drive the wavy scraper 84 toward the inner wall of the long box 81. When the round surface of the round block 86 does not push the semicircular part of the contact plate 85, under the action of the spring force corresponding to the positioning rod 83, the positioning rod 83 pushes the wavy scraper 84 to reset and move, and so on. The wavy scraper 84 scrapes the surface of the dehumidification block 82. Scraping the surface of the dehumidification block 82 can drive the surrounding air to flow, promote the exchange between humid air and the dehumidification block 82, and accelerate the speed of moisture adsorption.

[0035] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
