Description

Technical Field

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

[0002] At present, electrochemical energy storage refers to the process of energy storage, release and management completed by batteries. It uses chemical reactions to convert chemical energy and electrical energy to store energy. Depending on the storage device, electrochemical energy storage can be mainly divided into lead-acid batteries, sodium-sulfur batteries, flow batteries and lithium-ion batteries. This technology has the advantages of high energy density, high conversion efficiency, fast response speed, etc. It can flexibly configure power and energy and is almost unaffected by external climate and geographical factors.

[0003] Many existing electrochemical energy storage systems in the prior art have failed to fully optimize the thermal management strategy in their design, resulting in the heat generated during the charge and discharge cycle being difficult to dissipate effectively, which not only reduces the efficiency and service life of the battery, but may also cause safety risks such as thermal runaway and fire. Although some systems attempt to alleviate this problem through external cooling systems, these systems are often complex and energy-intensive, increasing overall operating costs. Secondly, the protective measures of the prior art in response to harsh environmental conditions (such as rain and snow) are not perfect. Many electrochemical energy storage devices lack intelligent environmental perception and response mechanisms, and cannot automatically adjust the working state or initiate protective measures according to changes in external conditions, thereby increasing the risk of equipment damage. Furthermore, fire safety is a major problem that needs to be solved in the field of electrochemical energy storage. Although many systems are equipped with fire alarms and fire extinguishing devices, the response speed and fire extinguishing effect of these devices are often unsatisfactory. Especially in large energy storage power stations, once a fire occurs, the fire may spread rapidly, causing serious consequences. The fire extinguishing devices in the prior art often lack the ability to accurately locate and respond quickly, making it difficult to extinguish the fire in the early stages.

[0018] The following will be combined with the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0019] Example 1 like Figure 1 to Figure 9 As shown, an electrochemical energy storage protection device includes a housing 1, a battery body 2, a first electrolyte storage tank 21, a second electrolyte storage tank 22 and a circulating cooling pipe 3, the battery body 2 is installed in the middle of the housing 1, the first electrolyte storage tank 21 is installed on the left side of the housing 1, and the second electrolyte storage tank 22 is installed on the right side of the housing 1, the circulating cooling pipe 3 passes through the interior of the housing 1, and the first electrolyte storage tank 21 and the second electrolyte storage tank 22 are both connected to the battery body 2 with a liquid outlet pipe 23 and a liquid inlet pipe 24, and a circulating pump 25 is installed on the liquid inlet pipe 24; A water pump 31 is installed at one end of the circulation cooling pipe 3, and two wheels 321 are rotatably installed inside the circulation cooling pipe 3. A rotating shaft 32 is fixedly connected to one side of the wheel 321. An active bevel gear 322 is fixedly sleeved on the outer circumference of the rotating shaft 32. Two follower shafts 33 are rotatably installed inside the shell 1. A follower bevel gear 331 is fixedly sleeved on the outer circumference of the follower. The active bevel gear 322 is meshed with the follower bevel gear 331. A cooling fan blade 332 is fixedly connected to the top of the follower shaft 33. Through the arrangement of the circulation pump 25, the water pump 31 and other structures, when the equipment is running, by turning on the circulation pump 25 and the water pump 31, the electrolyte circulates and reacts in the battery body 2, and the cooling contact space is increased by the surrounding liquid outlet pipe 23 and the circulation cooling pipe 3, which drives the wheel 321, the rotating shaft 32, the bevel gear and other components to operate, and drives the cooling fan blade 332 to replace hot air, thereby improving the cooling effect and service life of the equipment.

[0020] like Figure 1~Figure 5 As shown, the liquid outlet pipe 23 surrounds from top to bottom, and the circulating cooling pipe 3 surrounds the liquid outlet pipe 23 and the battery body 2 to increase the contact area between the liquid outlet pipe 23 and the circulating cooling pipe 3. The first cooling net 10, the second cooling net 101 and the third cooling net 102 are arranged in parallel.

[0021] In this embodiment, when the device is in use, the circulation pump 25 on the liquid inlet pipe 24 on one side of the first electrolyte storage tank 21 and the second electrolyte storage tank 22 is turned on, so that the liquid inlet pipe 24 delivers the electrolyte in the electrolyte storage tank to the inside of the battery body 2 for reaction. When the liquid inlet pipe 24 is delivered, the electrolyte inside the battery body 2 is squeezed by the electrolyte entering from the outside, and the liquid is discharged from the liquid outlet pipe 23. The liquid outlet pipe 23 is arranged to surround from top to bottom, which can increase the cooling contact space of the liquid outlet pipe 23 when the liquid is discharged. When the circulation pump 25 is turned on, the reaction of the battery body 2 will generate heat during the reaction process. At this time, the water pump 31 on the circulating cooling pipe 3 is turned on. The circulating cooling pipe 3 is connected to the tank body for storing cooling liquid externally. By turning on the water pump 31, the external cooling liquid is delivered to the inside of the circulating cooling pipe 3 for circulation cooling. The circulating cooling pipe 3 surrounds the liquid outlet pipe 23 and the battery body. On both sides of the body 2, during the circulation of the cooling liquid, the heat on the liquid inlet pipe 24 and the battery body 2 is continuously taken away. At this time, when the cooling liquid circulates, the rotating wheel 321 inside the circulating cooling pipe 3 is driven to rotate. During the rotation of the rotating wheel 321, the rotating shaft 32 is driven to rotate. During the rotation of the rotating shaft 32, the active bevel gear 322 is driven to rotate. The active bevel gear 322 drives the follower bevel gear 331 to rotate through the engagement with the follower bevel gear 331. The rotation of the follower bevel gear 331 causes the follower shaft 33 to rotate. The rotation of the follower shaft 33 causes the cooling blades 332 to rotate. The cooling blades 332 rotate through the first cooling net 10, the second cooling net 101 and the third cooling net 102, so as to bring the external air into the shell 1, replace and send out the hot air generated by the use of the equipment, thereby improving the overall cooling of the equipment and improving the service life of the equipment.

[0022] Example 2 like Figure 1 to Figure 7 As shown, two symmetrically arranged first cooling nets 10 are fixedly connected to the top of the shell 1, two symmetrically arranged second cooling nets 101 and two symmetrically arranged third cooling nets 102 are fixedly connected to the bottom of the shell 1, eight symmetrically arranged inner groove shafts 12 are fixedly connected to the top of the shell 1, and the inner groove shafts 12 are slidably equipped with sliding shafts 15. The tops of every four sliding shafts 15 are commonly fixedly connected with a rainwater collecting frame 16, the bottom of the rainwater collecting frame 16 is fixedly connected with a waterproof net 18, and one side of the rainwater collecting frame 16 is fixedly connected with a water outlet pipe 17. Through the arrangement of structures such as the rainwater collecting frame 16 and the fire alarm 58, in rainy and snowy weather or fire situations, the equipment prevents rain and snow from invading through the rainwater collecting frame 16 and the waterproof net 18 to protect internal components; when the fire alarm 58 is triggered, the servo motor 4 and the rotating motor 5 are started, the closing plate 43 slides to close the battery body 2, and at the same time the cover plate 511 opens to release the fire extinguishing agent to ensure the safety of the equipment.

[0023] like Figure 7As shown, a spring 14 is commonly connected between the inner groove shaft 12 and the sliding shaft 15 , and dampers 13 are installed at both ends of the spring 14 .

[0024] like Figure 1 to Figure 9 As shown, two symmetrically arranged fire extinguishing agent storage frames 56 are fixedly connected to the top of the shell 1, a rotating motor 5 is installed on one side of one of the fire extinguishing agent storage frames 56, a transmission shaft 54 ​​and two rotating shafts 51 are rotatably installed inside the shell 1, a driving gear 53 and a follower gear 55 are fixedly sleeved on the outer circumference of one of the rotating shafts 51 and the transmission shaft 54, the driving gear 53 is meshed with the follower gear 55, a transmission belt 52 is commonly installed on the outer circumference of the two rotating shafts 51, a cover plate 511 is fixedly sleeved on the outer circumference of one of the rotating shafts 51 and the transmission shaft 54, a fire extinguishing agent placement port 57 is fixedly connected to the top of the fire extinguishing agent storage frame 56, and a fire alarm 58 is installed at the bottom of the fire extinguishing agent storage frame 56.

[0025] like Figure 8 As shown, two symmetrically arranged servo motors 4 are installed inside the shell 1, and the output end of the servo motor 4 is connected to a coaxially arranged forward and reverse screw rod 42 through a coupling. Two symmetrically arranged limit rods 44 are fixedly connected inside the shell 1, and two symmetrical closing plates 43 are movably sleeved on the outer peripheral surfaces of the forward and reverse screw rods 42 and the limit rods 44.

[0026] like Figure 8 As shown, two symmetrically arranged sliding grooves are provided inside the housing 1, and four closing plates 43 are respectively slidably assembled inside the two sliding grooves, and the screw rods on both sides of the forward and reverse screw rods 42 are in opposite directions.

[0027] like Figure 8 As shown, a semicircular notch is provided in the middle of the closing plate 43 , and when the two semicircular notches are fitted together, they fit with the outer peripheral surface of the liquid outlet pipe 23 .

[0028] In this embodiment, when the equipment is cooling down and there is rain and snow outside, the rain and snow fall into the rainwater collecting frame 16. When the water output of the water outlet pipe 17 is less than the amount of rain and snow, the rainwater collecting frame 16 is lowered by the setting of the spring 14 and the sliding shaft 15. The spring 14 is provided with a damper 13 to prevent the spring 14 from shaking when not in use. When the rainwater collecting frame 16 is lowered, the waterproof net 18 covers the first cooling frame. After covering, it can effectively prevent the rain and snow water from flowing into the shell 1 from the first cooling frame when the rain and snow are heavy outside, thereby improving its protectiveness. When the fire alarm 58 at the bottom of the fire extinguishing agent storage frame 56 detects an alarm, it sends a signal to the external controller, and the external controller turns on the servo motor 4 and the rotating motor 5 inside the equipment. The start of the servo motor 4 causes the forward and reverse screw rods 42 to rotate. The forward and reverse screw rods 42 are composed of two opposite screw rods. When the forward and reverse screw rods 42 rotate When the closure plate 43 is in the closed state, the closing plate 43 is driven to slide toward the middle of the shell 1. During the sliding process of the closing plate 43, the limiting rod 44 limits it. During the closing process, the semicircular notch on the closing plate 43 fits with the liquid outlet pipe 23, so that it completely closes the battery body 2. At this time, the rotating motor 5 rotates synchronously. The rotation of the rotating motor 5 causes one of the rotating shafts 51 to rotate. This rotating shaft 51 drives the other rotating shaft 51 to rotate through the transmission belt 52. When the rotating shaft 51 rotates, the driving gear 53 and the driven gear 55 are engaged to drive the transmission shaft 54 ​​to rotate, so that the rotation directions of one of the rotating shafts 51 and the transmission shaft 54 ​​are opposite. When the rotating shaft 51 and the transmission shaft 54 ​​rotate, the cover plate 511 is opened, so that the fire extinguishing agent in the fire extinguishing agent storage frame 56 falls to both sides of the battery body 2 due to gravity to extinguish the fire, thereby improving the safety of the equipment.

[0029] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
