Description

Technical Field

[0001] The present invention belongs to the technical field of energy storage cabinets, and in particular relates to a liquid-cooled energy storage battery cabinet with autonomous dehumidification. Background Art

[0002] Energy storage is an important part of new energy construction, and in the energy storage system, the battery is the core that determines the performance of the energy storage system. Whether the battery can work stably for a long time depends largely on whether the battery system can operate within the appropriate temperature range. At present, energy storage cabinets usually use liquid cooling to dissipate heat from the battery to ensure long-term normal use of the battery. When liquid cooling is used for heat dissipation, the temperature difference between the liquid cooling plate and the air is large, so water vapor will be formed and condensation will be produced. In order to ensure the normal use of the energy storage cabinet, dehumidification is currently used in the energy storage cabinet to avoid the problem of water accumulation in the energy storage cabinet.

[0003] At present, the dehumidification method generally opens a drainage groove at the bottom of the energy storage cabinet to drain the accumulated water, and ventilates the inside of the energy storage cabinet to prevent water vapor from remaining inside the energy storage cabinet. However, there are still some problems in the actual use of the dehumidification mechanism. At present, ventilation is carried out by using a fan, and in order to ensure that external dust does not enter, a dustproof net is installed on the outside of the fan. However, after long-term use, a lot of dust will adhere to the surface of the dustproof net, which will cause the filter holes to be blocked, thereby reducing the permeability of the filter, so the staff needs to frequently clean and replace the filter. In addition, the effect of opening a drainage groove at the bottom of the energy storage cabinet is poor. Since the batteries of the energy storage cabinet are stacked, condensed water is easy to remain between the batteries and cannot be discharged in time, resulting in poor dehumidification effect of the energy storage cabinet.

The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0025] The embodiment of the present invention provides a liquid-cooled energy storage battery cabinet with autonomous dehumidification, such as Figure 1-6As shown, it includes a cabinet 1, a placement plate 2 is installed on the inner wall of the cabinet 1, a battery body 3 is placed on the upper end of the placement plate 2, a ventilation slot 4 is opened on the surface of the placement plate 2, the placement plate 2 is arranged in four groups, and the ventilation slots 4 on the surfaces of the four groups of placement plates 2 are staggered, a fan 5 is installed on the top of the cabinet 1, a filter screen 6 is installed above the fan 5 corresponding to the top of the cabinet 1, a support frame 7 is installed on the top of the cabinet 1 corresponding to the filter screen 6, a motor 8 is installed on the top of the support frame 7, the output shaft of the motor 8 extends to the bottom of the support frame 7 and is connected to a brush plate 9, the brush plate 9 is in contact with the upper surface of the filter screen 6, and a fixing frame is installed on the bottom of the cabinet 1 10, a bracket 11 is installed on the inner wall of the fixing frame 10, a connecting shaft 12 is rotatably installed at the center of the bracket 11, a spiral blade 13 is installed on the side of the connecting shaft 12, a tachometer 14 is installed above the bracket 11, a speed measuring mechanism of the tachometer 14 is connected to the top of the connecting shaft 12, and the tachometer 14 is electrically connected to the on-off switch of the motor 8 and the controller. When the energy storage cabinet needs to be dehumidified, the fan 5 is started, and the fan 5 draws external air into the interior of the cabinet 1. The air entering the cabinet 1 is blown toward the surface of the battery body 3, and then flows downward from the ventilation slot 4 on the surface of the placement plate 2, and passes through each battery in turn along this path. The body 3 is finally discharged outward from the fixing frame 10 at the bottom of the cabinet 1. The device can guide the airflow by arranging staggered ventilation slots 4 on the surface of the placement plate 2 so that it can be evenly blown to the surface of each battery body 3, thereby effectively improving the dehumidification effect of the energy storage cabinet. After the fan 5 is used for a long time, a lot of dust will adhere to the surface of the filter 6 above the fan 5. If it is not cleaned in time, the permeability of the filter 6 will be reduced, thereby reducing the airflow and causing the dehumidification effect to be unsatisfactory. Here, a spiral blade 13 and a tachometer 14 are installed on the inner side of the fixing frame 10. When the airflow speed is reduced, the tachometer 14 measures The speed of the connecting shaft 12 is reduced. When the speed is reduced to the set value, the controller controls the switch of the motor 8 to turn on. At this time, the motor 8 drives the brush plate 9 to rotate to scrape and clean the surface of the filter 6. The dust on the surface of the filter 6 is brushed off to enable the energy storage cabinet to dehumidify normally. The device ventilates the energy storage cabinet by setting a fan 5 to achieve dehumidification of the energy storage cabinet, and the spiral blade 13 cooperates with the tachometer 14 to determine whether the filter 6 needs to be cleaned according to the air flow speed. Through this setting, the automatic cleaning of the filter 6 can be achieved, which improves the convenience of cleaning the energy storage cabinet and also ensures the normal dehumidification of the energy storage cabinet for a long time.

[0026] The surface of the filter 6 is set to be spherical, the brush plate 9 is set to be arc-shaped and fits with the upper surface of the filter 6, the top inner wall of the cabinet 1 is set to be circular, an inclined groove is opened on the top surface of the cabinet 1, and an ash box 15 is installed on the outer side of the inclined groove corresponding to the outer wall of the cabinet 1. By setting the filter 6 to be spherical, when the brush plate 9 scrapes the upper surface of the filter 6, the agglomerated dust rolls off the surface of the filter 6 under the action of gravity. This setting can prevent the scraped dust from remaining on the surface of the filter 6. By providing the ash box 15, the scraped dust can be collected to facilitate subsequent cleaning.

[0027] The outer wall of the cabinet 1 is provided with a limit frame which is matched with the size of the ash box 15. The ash box 15 is placed in the limit frame of the outer wall of the cabinet 1.

[0028] Both ends of the brush plate 9 are connected with scrapers 16, and the scrapers 16 are in contact with the top inner wall of the cabinet 1. The scrapers 16 are arranged and installed at both ends of the brush plate 9. When the brush plate 9 cleans the surface of the filter 6, the scrapers 16 will be driven to rotate. The rotating scrapers 16 can scrape the fallen dust into the inclined groove on the top of the cabinet 1, and the dust will fall into the ash box 15 from the inclined groove. Through this arrangement, auxiliary dust collection can be achieved.

[0029] A groove is provided at the upper end of the frame of the fan 5, in which a limit plate 17 is inserted, and the filter 6 is installed at the upper end of the limit plate 17. By setting the limit plate 17, the lower side of the filter 6 is connected to the limit plate 17, and the limit plate 17 is inserted at the top of the outer frame of the fan 5. When the filter 6 needs to be disassembled and replaced, it can be directly pulled upwards, thereby improving the convenience of disassembly and assembly of the filter 6.

Through grooves 20 are evenly provided on the surface of the placement plate 2. The placement plate 2 is set as a hollow structure and communicates with the through grooves 20. The internal compartment of the placement plate 2 is communicated with the lower water trough 18. The lower water trough 18 is provided, and the lower water trough 18 is communicated with the through groove 20 on the surface of the placement plate 2. When condensation water is generated on the surface of the battery body 3 due to temperature difference, the condensation water will flow from the through groove 20 to the lower water trough 18, and finally be discharged from the drain pipe 19, thereby realizing the removal of water accumulation in the energy storage cabinet.

[0031] A support plate 21 is installed on the surface of the placement plate 2, and the support plates 21 are evenly distributed along the horizontal direction of the placement plate 2 surface. By providing the support plate 21, the support plate 21 can raise the battery body 3 and place it, thereby avoiding water accumulation at the bottom of the battery body 3 and causing corrosion of the shell.

[0032] A groove is horizontally provided on the surface of the placement plate 2, and a screw 22 is rotatably installed inside the groove. A connecting sleeve 23 is threadedly connected to the surface of the screw 22, and a first positioning plate 24 is installed on the top of the connecting sleeve 23. A second positioning plate 25 is fixedly installed on the surface of the placement plate 2. By providing the first positioning plate 24, after the battery body 3 is placed in, the screw 22 can be rotated, and the connecting sleeve 23 slides horizontally under the action of the thread on the surface of the screw 22, thereby driving the first positioning plate 24 to clamp and fix the battery body 3, thereby improving the stability of the placement of the battery body 3 and preventing the wiring harness from loosening due to the movement of the battery body 3.
