Description

Technical Field

[0001] The invention relates to the technical field of explosion relief, and in particular to a sliding explosion relief device applied to an energy storage battery cabinet. Background Art

[0002] A battery cabinet is a device used to store batteries. It is divided into many different types according to its type and purpose, such as a single battery cabinet: mainly used to charge and discharge multiple newly assembled single batteries multiple times, so as to check the performance of each aspect of the single battery, and prevent the single battery from causing harm to the surrounding operators when the single battery is tested; a combination battery cabinet: mainly used to detect the series connection, parallel connection, and charge balancing of multiple combination batteries that have just been assembled. The structure is more complex than that of a single battery cabinet; and a battery storage and transportation cabinet that is simply used to store and move batteries. These cabinet-mounted devices with batteries stored inside can be collectively referred to as a battery cabinet.

[0003] Conventional battery storage and transportation cabinets and battery cabinets used for testing batteries are usually equipped with explosion relief devices. When the battery inside the battery cabinet experiences thermal runaway due to various reasons, this explosion relief device can open an opening to discharge the flammable gas inside the equipment, thereby preventing excessive pressure inside the battery cabinet, which may lead to battery explosion. This device installed on the battery cabinet for explosion relief can be called an explosion relief device applied to energy storage battery cabinets.

[0004] However, this explosion relief device applied to the energy storage battery cabinet can only open one opening for explosion relief, and its explosion relief rate is low. When there are many batteries inside the battery cabinet, the emission rate of the combustible gas may not keep up with the generation rate of the combustible gas. Moreover, this explosion relief device can only simply discharge the combustible gas inside the equipment, and cannot prevent abnormal batteries. After the opening is opened to start discharging the combustible gas, the batteries inside the equipment may continue to react abnormally to produce combustible gas or even explode. Therefore, it does not meet the existing needs. In this regard, we propose a sliding explosion relief device applied to energy storage battery cabinets. Summary of the invention

DETAILED DESCRIPTION

[0019] The technical solutions in the embodiments of the present invention will be described clearly and completely 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.

[0020] See also Figures 1 to 6The present invention provides a sliding explosion relief device for an energy storage battery cabinet, comprising a battery cabinet 1. An efficient explosion relief mechanism is arranged on the outer side of the top end of the battery cabinet 1. The efficient explosion relief mechanism comprises a top cover plate 6, a sealing sleeve 28, a pushing mechanism, a fixing mechanism and a rebound mechanism. The interior of the sealing sleeve 28 is in contact with the outer surface of the battery cabinet 1, and the lower end surface of the top cover plate 6 is in contact with the upper end surface of the sealing sleeve 28. The sealing sleeve 28 can be pushed upward by the pushing mechanism, the fixing mechanism can fix the sealing sleeve 28 in contact with the lower end surface of the top cover plate 6, and the rebound mechanism can push the sealing sleeve 28 downward.

[0021] A cabinet door 29 is provided on one side of the outer surface of the sealing sleeve 28, and a control panel 31 is provided on one side of the cabinet door 29. A base 4 fixed to the lower end surface of the battery cabinet 1 is provided below the control panel 31, and a support frame 5 is fixedly provided at the four end corners of the upper end surface of the base 4. The surface of the support frame 5 facing the top cover plate 6 is fixed to the top cover plate 6, and the battery cabinet 1, the battery submersible mechanism 2 and the high-efficiency explosion-proof mechanism are all electrically connected to the control panel 31; the battery cabinet 1, the battery submersible mechanism 2 and the high-efficiency explosion-proof mechanism can be controlled by the control panel 31.

[0022] When the equipment needs to be used, the cabinet door 29 located on the outer surface of the sealing sleeve 28 is opened, and any number of batteries 3 are placed on the upper end surfaces of the two battery supporting plates 202. The batteries 3 are then connected to various test data cables on the battery cabinet 1, and various aspects of the test are performed on them. In this embodiment, the battery cabinet can be used in the energy storage power station.

[0023] The fixing mechanism includes a fixed motor 17, the output shaft of the fixed motor 17 is connected to a fixed shaft 18 through a coupling, a first bevel gear 19 is provided on the lower fixed sleeve of the outer surface of the fixed shaft 18, a second bevel gear 20 is meshed on both sides of the outer surface of the first bevel gear 19, the axis of the second bevel gear 20 is connected to a bevel gear shaft 21 connected to the inside of the top cover plate 6 through a roller bearing, the bevel gear shaft 21 is fixedly connected to a square shaft 22 on the surface facing the inner wall of the sealing sleeve 28, an inner thread groove 23 located on the outer surface of the top cover plate 6 is provided on the outer side of the top end of the square shaft 22, a fixed thread head 30 matching its inner thread is provided inside the inner thread groove 23, and the fixed thread head 30 faces A square slot 24 is provided on the surface of the bevel gear shaft 21, and the square shaft 22 is inserted into the inside of the square slot 24; if thermal runaway occurs in the battery 3 during the detection of the battery 3 and is detected by the battery cabinet 1, the fixed motor 17 will be automatically started, and the fixed motor 17 can drive the fixed shaft 18 connected thereto and the first bevel gear 19 fixedly sleeved on the outer surface of the fixed shaft 18 to rotate together. When the first bevel gear 19 rotates, the two second bevel gears 20 meshing therewith and the bevel gear shaft 21 connected to the axis of the second bevel gear 20 will rotate synchronously therewith, and the rotating bevel gear shaft 21 can drive the square shaft 22 connected thereto to rotate.

[0024] The inner wall cross-section of the square slot 24 is a square, the outer surface of the square shaft 22 fits with the inner wall of the square slot 24, and the square shaft 22 and the square slot 24 are slidingly connected; since the outer surface of the square shaft 22 fits with the inner wall of the square slot 24 located on the outer surface of the fixed thread head 30, when the square shaft 22 rotates, the fixed thread head 30 will rotate therewith, and under the transmission of the thread structure, the rotating fixed thread head 30 will move inward or outward accordingly.

[0025] An internal thread fixing groove 25 located on the inner wall of the sealing sleeve 28 is provided on the outer side of the top end of the fixed thread head 30, and the external thread of the fixed thread head 30 matches the internal thread of the internal thread fixing groove 25; when the top end of the fixed thread head 30 is located inside the internal thread fixing groove 25 on the inner wall of the sealing sleeve 28, the sealing sleeve 28 will be fixed by the two fixed thread heads 30 in a state of being in contact with the top cover plate 6, and when thermal runaway occurs in the battery 3, the two fixed thread heads 30 are synchronously moved inward by the fixing motor 17.

[0026] Furthermore, the rebound mechanism includes two metal rods 14, and a metal sleeve 15 is movably sleeved on one side of the outer surface of the metal rod 14. The upper end surface of the metal sleeve 15 is connected to a second spring 16 sleeved on the outer surface of the metal rod 14, and the surface of the metal sleeve 15 facing the inner wall of the sealing sleeve 28 is fixed to the sealing sleeve 28; when the fixed thread head 30 completely leaves the inside of the internal thread fixing groove 25, the sealing sleeve 28 will move downward under the spring force of the second spring 16 indirectly connected thereto, and as the internal thread fixing groove 25 descends, the battery 3 sealed by the sealing sleeve 28 will be directly exposed to the outside, thereby discharging the combustible gas. The above technical solution improves the discharge efficiency of the equipment for combustible gas.

[0027] A circular metal ring 26 fixed to the upper side of the inner wall of the sealing sleeve 28 is provided below the two fixed threaded heads 30, and a rubber shock-absorbing ring 27 is fixed to the lower end face of the circular metal ring 26, and the rubber shock-absorbing ring 27 is made of an integrated shock-absorbing rubber; as the sealing sleeve 28 descends, the circular metal ring 26 fixed thereto and the rubber shock-absorbing ring 27 fixed to the lower end face of the circular metal ring 26 will move downward together, and when the lower end face of the rubber shock-absorbing ring 27 contacts the upper end face of the battery cabinet 1, the sealing sleeve 28 will stop descending, and the rubber shock-absorbing ring 27 can reduce the impact force when the sealing sleeve 28 collides with the battery cabinet 1, thereby protecting the battery cabinet 1 and the sealing sleeve 28.

[0028] Furthermore, the pushing mechanism includes a stepper motor 7, the output shaft of the stepper motor 7 is connected to a transmission shaft 8 through a coupling, a threaded transmission rod 9 is provided on both sides of the transmission shaft 8, and two threaded transmission rods 9 are connected in series with one transmission shaft 8 through a synchronous chain 10 respectively; The upper end surface of the threaded transmission rod 9 is fixedly connected with a lifting threaded rod 11, and the lower side of the outer surface of the lifting threaded rod 11 is connected with a pushing sleeve 12 through a threaded structure, and one side of the lifting threaded rod 11 is provided with a guide rod 13 that vertically moves through the pushing sleeve 12; when the battery 3 is exposed to the outside, the intensity of the thermal runaway phenomenon of the battery 3 gradually decreases and no longer produces flammable gas, the staff takes down the battery 3 with the intensity of the overheating runaway phenomenon, and then starts the stepper motor 7, and the stepper motor 7 can drive the transmission shaft 8 connected thereto and the threaded transmission rod 9 connected in series with the transmission shaft 8 through a synchronous chain 10 to rotate, and when the threaded transmission rod 9 rotates, the lifting threaded rod 11 fixed thereto will rotate together, because the pushing sleeve 12 connected to the lifting threaded rod 11 through the threaded structure is vertically penetrated by the guide rod 13, so the pushing sleeve 12 itself cannot rotate, and when the lifting threaded rod 11 rotates, the pushing sleeve 12 that cannot rotate by itself will move up and down under the transmission of the threaded structure. At this time, the pushing sleeve 12 is moved upward. As the pushing sleeve 12 descends, the pushing sleeve 12 will contact the metal sleeve 15 fixed between the inner wall of the sealing sleeve 28 and push the metal sleeve 15 outward. As the metal sleeve 15 rises, the sealing sleeve 28 fixed thereto will move upward together. When the two internal thread fixing grooves 25 located on the inner wall of the sealing sleeve 28 move to the positions corresponding to the two fixed thread heads 30 respectively, the two fixed thread heads 30 are synchronously moved outward by the fixing motor 17 until the top ends of the two fixed thread heads 30 enter the interior of the internal thread fixing grooves 25 again, so as to fix the sealing sleeve 28. When the sealing sleeve 28 is fixed again, the pushing sleeve 12 is moved downward by the stepping motor 7. When the pushing sleeve 12 can no longer move downward, the stepping motor 7 is turned off and the battery cabinet 1 can be used again to test the battery 3. The above technical solution can automatically push the sealing sleeve 28 back to its original position and fix it.

[0029] A battery submersible mechanism 2 is provided inside the sealing sleeve 28, and the battery submersible mechanism 2 includes two battery carrier plates 202, a square groove 201, a salt water box 216, a salt water 217 and a flip mechanism. From left to right, the front end surface of the first battery carrier plate 202 and the rear end surface of the second battery carrier plate 202 are connected to the inner wall of the square groove 201 through a rotating shaft, and a battery 3 is placed on the upper end surface of the two battery carrier plates 202; The salt water box 216 is located below the two battery supporting plates 202, and the salt water 217 is located inside the salt water box 216. The flip mechanism can make the two battery supporting plates 202 rotate around the connecting point of the rotating shaft.

[0030] Furthermore, the flipping mechanism includes a horizontal bar cylinder 214, the piston rod of which is fixedly connected to the second push block 212, a first push block 211 is provided below the second push block 212, and the surface of the first push block 211 facing the second push block 212 is a second inclined surface 213; the lower end surface of the first push block 211 is fixedly connected to a fixed plate 205, a cylindrical groove 207 is provided inside the fixed plate 205, a circular sleeve 208 fitting with the inner wall of the cylindrical groove 207 is provided inside the cylindrical groove 207, a guide rod 209 is connected to the axis of the circular sleeve 208, a first spring 210 is provided on one side of the outer surface of the guide rod 209, and the two ends of the first spring 210 are respectively connected to the cylindrical groove 207 and the interior of the battery cabinet 1.

[0031] An L-shaped fixing rod 204 is provided on one side of the fixing plate 205, the lower end face of which is fixed to the battery supporting plate 202, and the surface of the fixing plate 205 facing the L-shaped fixing rod 204 is a first inclined surface 206; when the battery supporting plate 202 is in a parallel state, the top end of the L-shaped fixing rod 204 fixed to the upper end face of the battery supporting plate 202 is in contact with the upper end face of the fixing plate 205, and the battery supporting plate 202 can be fixed by the L-shaped fixing rod 204 in contact with the upper end face of the fixing plate 205, thereby preventing the battery supporting plate 202 in a parallel state from rotating without authorization.

[0032] When the battery 3 has been exposed to the outside, but the thermal runaway phenomenon of the battery 3 becomes more and more serious, the second pushing block 212 is pushed downward by the horizontal cylinder 214. As the second pushing block 212 descends, the second pushing block 212 will contact the second inclined surface 213 located on the outer surface of the first pushing block 211, and push the first pushing block 211 outward. As the first pushing block 211 moves, the fixing plate 205 fixed thereto will move outward together. When the upper end surface of the fixing plate 205 is no longer in contact with the top end of the L-shaped fixing rod 204, the fixation of the battery supporting plate 202 will be released. Thereafter, under the influence of gravity, the battery 202 placed on the upper end surfaces of the two battery supporting plates 202 will be released. The pool 3 will push the two battery supporting plates 202 to rotate around the shaft connection as the center, so as to open the two battery supporting plates 202, and the battery 3 will fall into the salt water 217 from between the two opened battery supporting plates 202. The subsequent reaction of the battery can be prevented by the salt water 217. The battery 3 can be quickly cooled by the salt water 217, and the salt water 217 has a high electrical conductivity, which can cause the battery 3 to short-circuit, thereby stopping the electrochemical reaction. At the same time, when the battery 3 falls into the salt water 217, the toxic gas or electrolyte inside the battery 3 can be prevented from leaking, thereby reducing the harm to the environment and personnel. The above technical solution can prevent the thermal runaway phenomenon of the battery 3 and prevent its explosion.

[0033] A rotating handle 203 is fixedly provided on one side of the upper end surface of the battery supporting plate 202, and a brine box sliding installation groove 215 is provided below the two rotating handles 203, and the brine box 216 is slidably installed inside the brine box sliding installation groove 215; when the fixed plate 205 is pushed outward, it will squeeze the first spring 210 connected to it. When the thermal runaway phenomenon of the battery 3 has ended, the rotating handle 203 located on the outer surface of the battery supporting plate 202 is manually grasped, and the rotating handle 203 is pulled upward to drive the battery supporting plate 202 to rotate around the shaft connection as the center. When the battery supporting plate 202 becomes flat again, After the battery supporting plate 202 is in the parallel state, the L-shaped fixing rod 204 fixed on the upper end surface of the battery supporting plate 202 will also return to its original angle, and then the second pushing block 212 will be pulled upward by the horizontal bar cylinder 214. With the rise of the second pushing block 212 and the reaction of the squeezed first spring 210, the fixing plate 205 will gradually move inward. When the upper end surface of the fixing plate 205 is again in contact with the lower end surface of the top end of the L-shaped fixing rod 204, the battery supporting plate 202 will be fixed in a parallel state again, and then the battery 3 can continue to be placed on the upper end surface of the battery supporting plate 202 and tested by the battery cabinet 1.

[0034] When the battery 3 falls into the brine 217 inside the brine box 216, the brine box 216 is pulled out from the inside of the brine box sliding mounting slot 215. At this time, do not take the battery 3 out of the brine 217 immediately. After the battery 3 has been soaked for forty-eight hours, take the battery 3 out and replace the brine 217. This is to prevent the subsequent reaction of the battery 3 from causing thermal runaway again.

[0035] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be considered exemplary and non-restrictive in all respects, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims be included in the present invention.
