[0015] Compared with the prior art, the beneficial effects of the present invention are:

[0016] 1. This invention, by providing multiple grooves and drawers, allows for the separate placement of batteries, preventing thermal runaway chain reactions and improving fire prevention capabilities. Each drawer independently places and removes battery modules, allowing users to use them as needed. It is equipped with an air inlet pipe, filter box, first branch pipe, second branch pipe, air pump, and filtration mechanism. When the air pump operates, gas enters the slots through the air inlet pipe and second branch pipe. After filtration by the filtration mechanism, the filter cotton first intercepts particulate matter, then it is adsorbed by the activated carbon adsorption plate. The filtered gas then enters the housing through the first connecting pipe, and after passing through the third and fourth connecting pipes, it can be ejected from multiple nozzles to dissipate heat from the battery modules. Furthermore, the air outlet allows hot air from the drawers to escape through the outlets. A dustproof net prevents dust from entering the drawers through the air outlets. This invention allows for independent placement of batteries, preventing thermal runaway chain reactions, and each drawer can independently dissipate heat, resulting in excellent heat dissipation.

[0017] 2. This invention features two sets of filtering mechanisms, a detachable mechanism, a first connecting pipe, and a second connecting pipe. When the filtering mechanism needs to be replaced, one of the filtering mechanisms can be replaced individually, while the other filtering mechanism is used to filter the air, avoiding affecting the heat dissipation of the battery module. When the filtering mechanism inside the upper slot needs to be replaced, the solenoid valve inside the upper second connecting pipe is closed, while the solenoid valve inside the lower second connecting pipe remains open. The air entering through the intake pipe can still enter the housing through the lower second connecting pipe, the filtering mechanism, and the first connecting pipe. Simultaneously, the two upper insert rods are pulled outwards, disengaging from the insertion holes. Inside, the frame is released from its limiting position. Under the action of the third spring, the frame is pushed outward from the slot, allowing the filter mechanism to be removed from the inside of the slot for cleaning or replacement. After cleaning or replacing the filter mechanism, the two insert rods are pulled outward to insert the frame into the slot. After the third spring is compressed, the frame is fully inserted into the slot. The insert rods are released, and under the action of the fourth spring, they are inserted into the inside of the socket to limit the frame. This invention, by setting two sets of filter mechanisms, ensures that when one set of filter mechanisms is replaced or cleaned, the other set of filter mechanisms can still filter the air, thereby ensuring the heat dissipation effect of the battery module.

Detailed Implementation

[0028] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0029] The air pump 23 (model 2XZ-0.25) mentioned in this invention can be obtained from the market or through private customization.

[0030] Please see Figures 1 to 9One embodiment of the present invention provides an energy storage battery cabinet, comprising a battery cabinet body 1. Eight grooves 3 are evenly distributed on the front end face of the battery cabinet body 1. A base 10 is fixedly installed on the front end face of the inner wall of each groove 3. A square groove 21 is provided on the front end face of the base 10. Multiple air jets 11 are evenly installed on the front end face of the square groove 21. A drawer 4 is movably installed on the inner side of each groove 3 via a limiting mechanism 5. A through groove 13 is provided on the rear end face of the drawer 4. A baffle 12 is movably disposed on the inner side of the through groove 13. The rear end face of body 1 is provided with a housing 2. A filter box 7 is installed in the middle of the rear end face of housing 2. An air inlet pipe 6 is installed on the rear end face of filter box 7. An air pump 23 is installed in the rear of the filter box 7 through a cavity 22. Slots 16 are provided on the front of the upper end face and the lower end face of filter box 7. A filter mechanism 17 is movably installed on the inner side of each slot 16 through a detachable mechanism 20. The air pump 23 is connected to the slots 16 through a second connecting pipe 19. The housing 2 is connected to the two slots 16 through a first connecting pipe 18.

[0031] The battery cabinet body 1 and the housing 2 are fixedly connected by four L-shaped support rods. A handle is installed on the front end of the drawer 4. Multiple vent holes 14 are evenly arranged on the bottom of the front end of the drawer 4. A dustproof net 15 is installed on the inside of the vent hole 14 to improve the stability of the connection between the housing 2 and the battery cabinet body 1. The drawer 4 can be pulled out by the handle, and the gas in the drawer 4 can be discharged through the vent hole 14. By setting the dustproof net 15, dust can be prevented from entering the drawer 4 through the vent hole 14.

[0032] The upper and lower two grooves 3 are connected to the housing 2 through the first branch pipe 8, and the four middle grooves 3 are connected to the first branch pipe 8 through the second branch pipe 9. A solenoid valve is installed on the inner side of the second connecting pipe 19. The jet head 11 is connected to the first branch pipe 8 through the third connecting pipe, and the second branch pipe 9 is connected to the jet head 11 through the fourth connecting pipe. The direction of airflow can be controlled by controlling the solenoid valve. When the air pump 23 is working, the gas enters the slot 16 through the air inlet pipe 6 and the second connecting pipe 19. After being filtered by the filter mechanism 17, it enters the housing 2 through the first connecting pipe 18. After passing through the third connecting pipe and the fourth connecting pipe, it can be sprayed out from the jet head 11 to dissipate heat from the energy storage battery.

[0033] The limiting mechanism 5 includes a slide plate 503, which is installed on both sides of the groove 3 via a slide groove 502. The slide plate 503 is connected to the inner wall of the slide groove 502 via a second spring 506. A locking block 508 is installed on one side of the outer surface of the two slide plates 503 that is opposite to each other. The locking block 508 can be moved by moving the slide plate 503.

[0034] The front end of the locking block 508 is provided with a first inclined surface 504, and the front of both sides of the outer surface of the drawer 4 is provided with a locking groove 505. The sliding groove 502 and the groove 3 are connected by a connecting groove. The locking block 508 passes through the connecting groove and can be locked into the inside of the locking groove 505. The locking block 508 can limit the drawer 4.

[0035] A second inclined surface 507 is provided on the rear of both sides of the outer surface of drawer 4. A first spring 501 is installed around the front end face of base 10. Limiting blocks are installed on the upper and lower ends of slide plate 503. Limiting grooves are provided on the upper and lower sides of the inner wall of slide groove 502, and the limiting blocks are inserted into the inner side of the limiting grooves. When the second inclined surface 507 contacts the first inclined surface 504, it will push the locking block 508 towards the inner side of slide groove 502. The locking block 508 is retracted into the inner side of slide groove 502 until the drawer is fully inserted into the inner side of groove 3. Then, multiple first springs 501 are compressed until the slot 505 is aligned with the connecting groove. Under the action of the second spring 506, the locking block 508 is pushed towards the inner side of slot 505. By setting the limiting blocks and limiting grooves, the sliding stability of slide plate 503 is improved.

[0036] A strip groove is provided through the front end face of the baffle 12, and a filter screen is installed on the inner side of the strip groove. Vertical plates are installed on both sides of the outer surface of the baffle 12. Vertical grooves are provided on both sides of the inner wall of the through groove 13, and the vertical plates can be inserted into the inner side of the vertical grooves. Gas entering from the outside can enter the front of the drawer 4 through the filter screen to dissipate heat from the energy storage battery and facilitate the disassembly and assembly of the baffle 12.

[0037] The filtration mechanism 17 includes a frame 1701. An activated carbon adsorption plate 1703 is installed at the front of the inner wall of the frame 1701, and a filter cotton 1702 is installed at the rear of the inner wall of the frame 1701. The gas entering the filter box 7 is first filtered by the filter cotton 1702, which intercepts particulate matter, and then adsorbs it by the activated carbon adsorption plate 1703, thus preventing the activated carbon pores from being blocked and extending its service life.

[0038] The detachable mechanism 20 includes a plug rod 2002, which is installed above and below the outer surfaces of the filter box 7 through through holes 2004. A fourth spring 2003 is sleeved on the outer surface of the plug rod 2002, and plug holes 2005 are provided on both sides of the outer surface of the frame 1701.

[0039] The insertion rod 2002 can be inserted into the inside of the insertion hole 2005. Multiple third springs 2001 are evenly installed on the inner wall of the slot 16. A limiting ring is sleeved on one side of the outer surface of the insertion rod 2002. One end of the fourth spring 2003 is fixedly connected to the outer surface of the limiting ring, and the other end of the fourth spring 2003 is fixedly connected to the inner wall of the through hole 2004 to improve the stability of the insertion rod 2002. The insertion rod 2002 can limit the frame 1701. Under the action of the third spring 2001, the frame 1701 can be pushed outward of the slot 16.

[0040] When in use, this energy storage battery cabinet is powered on. Multiple recesses 3 and drawers 4 allow for separate placement of battery modules, preventing thermal runaway chain reactions and improving fire prevention capabilities. Each drawer 4 independently accommodates and removes battery modules. A limit mechanism 5 is included; when a drawer 4 needs to be pulled out, the sliding plates 503 on both sides of one drawer 4 can be slid outwards simultaneously. The movement of the sliding plates 503 moves the locking blocks 508, disengaging them from the inner side of the slots 505 and releasing the limit on the drawer 4. Under the action of multiple first springs 501, the drawer 4 is pushed forward from the recesses 3. Users can easily pull the drawer 4 out from the inside of the recesses 3 using the handle to retrieve or place the battery modules. The drawer 4 can then be pushed back in. The groove 3 can be used as needed. It is equipped with an air inlet pipe 6, a filter box 7, a first branch pipe 8, a second branch pipe 9, a vacuum pump 23, and a filter mechanism 17. When the vacuum pump 23 is working, gas enters the slot 16 through the air inlet pipe 6 and the second branch pipe 9. After being filtered by the filter mechanism 17, the filter cotton 1702 first intercepts particulate matter, and then the activated carbon adsorption plate 1703 adsorbs it. The filtered gas then enters the housing 2 through the first connecting pipe 18, and after passing through the third and fourth connecting pipes, it can be sprayed out from multiple nozzles 11 to dissipate heat from the battery module. A vent 14 allows hot air from the drawer 4 to escape, and a dustproof net 15 prevents dust from passing through the vent 14. 4. Entering drawer 4, there are two sets of filter mechanisms 17, a detachable mechanism 20, a first connecting pipe 18, and a second connecting pipe 19. When the filter mechanism 17 needs to be replaced, one filter mechanism 17 can be replaced individually first, and the other filter mechanism 17 can be used to filter the air to avoid affecting the heat dissipation of the battery module. When the filter mechanism 17 inside the upper slot 16 needs to be replaced, the solenoid valve inside the upper second connecting pipe 19 is closed, while the solenoid valve inside the lower second connecting pipe 19 remains open. The air entering through the air intake pipe 6 can still enter the housing 2 through the lower second connecting pipe 19, the filter mechanism 17, and the first connecting pipe 18. At the same time, pull the two upper plug rods 2002 outward. When the insertion rod 2002 leaves the inside of the socket 2005, it releases the restriction on the frame 1701. Under the action of the third spring 2001, the frame 1701 is pushed outward of the slot 16, allowing the filter mechanism 17 to be removed from the inside of the slot 16 for cleaning or replacement. After cleaning or replacing the filter mechanism 17, pull the two insertion rods 2002 outward, inserting the frame 1701 into the inside of the slot 16. After the third spring 2001 is compressed, the frame 1701 is fully engaged in the slot 16. Release the insertion rod 2002, and under the action of the fourth spring 2003, insert the insertion rod 2002 into the inside of the socket 2005, restricting the frame 1701. This invention allows for independent placement of the battery module, avoiding a chain reaction of thermal runaway.Each drawer 4 can dissipate heat independently, resulting in good heat dissipation. Furthermore, by incorporating two sets of filters 17, it is ensured that while one set of filters 17 is being replaced or cleaned, the other set continues to filter the air, thus guaranteeing effective heat dissipation for the battery module.

[0041] 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 invention can be implemented in other specific forms without departing from its spirit or essential characteristics. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within the present invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
