Description

Technical Field

[0001] The present invention relates to the technical field of energy storage cabinets, and particularly to a liquid-cooled energy storage cabinet for outdoor use. Background Art

[0002] A liquid-cooled energy storage cabinet is a battery energy storage cabinet that dissipates heat and controls the temperature of energy storage batteries through a liquid-cooling system; the liquid-cooling system mainly consists of a cooling plate, cooling pipes, a water inlet pipe, a water outlet pipe, and a cooling water tank, etc. The cooling pipes are arranged in an S-shaped detour outside the cooling plate, and the coolant circulates in the cooling pipes, absorbs the heat generated by equipment such as battery modules inside the cabinet, and then flows back to the cooling water tank through the water inlet pipe. After being cooled, it re-enters the cooling pipes through the water outlet pipe to form a complete heat dissipation cycle.

[0003] When the temperature of the energy storage batteries in the energy storage cabinet is relatively high, the cooling water tank requires more energy consumption to cool down the heated liquid. To reduce this energy consumption, an air-cooling system can be set up. While assisting the liquid-cooling system to dissipate heat from the energy storage batteries, it can also dissipate heat from the heated liquid, reducing the energy consumption of the cooling water tank. However, when the liquid-cooled energy storage integrated machine is installed and used in outdoor scenarios, this poses higher requirements for outdoor protection conditions, and it is required to have functions of waterproof, dustproof, and preventing foreign objects from entering; however, during the operation of the equipment, the air-cooling system needs to maintain ventilation to dissipate heat inside.

The side wall of the cooling board is fixedly connected to the outlet pipe. The side wall of the cooling board is fixedly connected to the side wall of the inlet pipe, which is used for liquid cooling and temperature reduction of the energy storage device in the cabinet body.

[0010] Preferably, a ventilation board is fixedly connected to the top of the installation frame. The side wall of the inlet pipe is fixedly connected to the side wall of the ventilation board, which is used to cooperate with the air cooling device to cool the liquid in the inlet pipe and reduce the energy consumption of the liquid cooling host.

[0011] Preferably, the driving device includes a motor. The side wall of the motor is fixedly connected to the side wall of the outer layer board. A first gear is fixedly connected to the output end of the motor. A second gear is rotatably connected to the side wall of the inner layer board. The first gear meshes with the second gear.

[0013] The present invention provides a liquid-cooled energy storage cabinet for outdoor use, which has the following beneficial effects: (1). For this energy storage cabinet, through the driving device and the cleaning device, during use, the motor starts to drive the first gear to rotate, and drives the second gear to rotate synchronously. The driving block at the edge of the second gear then makes a circular motion. During the motion of the driving block, it slides and fits with the inner wall of the driving frame, converting the circular motion into a linear reciprocating motion of the driving frame and the connecting rod. The connecting rod drives the rotating shaft and the slider to slide up and down along the side wall of the inner layer board, so that the brush roller cleans the ventilation filter screen, realizing the automatic cleaning of the ventilation filter screen.

[0014] (2) When in use, for this energy storage cabinet, through the dust removal device, the driving device is started. During the process of driving the slider to slide downward, the pressing device drives the air pressure plate to slide downward in the air storage box, compressing the return spring. The air in the air storage box is discharged from the air outlet head through the second one-way valve, and an air flow is formed through the air outlet device to blow the dust on the bottom wall of the dust collection channel out of the cabinet, reducing the influence of dust accumulation on the ventilation and operation of the energy storage cabinet.

[0015] (3) When in use, for this energy storage cabinet, through the partition device, when the slider of the cleaning device slides upward, it will contact the push plate and apply a thrust force. The push plate drives the sliding rod to move upward synchronously, and then the upper pressing plate fixed at the bottom end of the sliding rod squeezes the partition plate upward; the partition plate rotates with the connecting shaft as the fulcrum. During this process, the torsion spring is compressed, and the partition plate that originally horizontally closes the ventilation channel tilts and opens, causing the dust brushed off and accumulated on the partition plate by the cleaning device to fall into the dust collection channel under the action of gravity; when the slider finishes moving upward and starts to slide downward, the upper pressing plate no longer applies force to the partition plate, and the torsion spring gradually releases the stored elastic potential energy, driving the partition plate to rotate reversely around the connecting shaft and reset to its original horizontal state, closing the ventilation channel again to prevent the air flow from blowing the dust back to the ventilation filter screen during the subsequent operation of the dust removal device, ensuring the cleanliness and stability of the internal air flow path of the cabinet.

[0016] (4) When in use, for this energy storage cabinet, through the air outlet device, the sliding rod is driven to drive the abutting plate to move downward. The abutting plate pushes the downward pressing rod and the air pressure plate to slide downward in the air storage box, compressing the return spring. The air in the air storage box is discharged from the air outlet head through the second one-way valve and enters the air outlet frame; at this time, the air flow with a certain pressure impacts the side wall of the inclined air outlet frame, pushing open the cover plate that adheres to the side wall under the action of gravity, and the air forms an air flow through the air outlet to blow the dust in the dust collection channel out of the cabinet. When the air flow stops, the cover plate adheres to the side wall of the air outlet frame again under the action of gravity, which can prevent foreign matters such as rainwater and dust from entering the interior of the energy storage cabinet through the air outlet, enabling the energy storage cabinet to achieve dust removal while ensuring good protection performance, so that the energy storage cabinet can operate stably in the outdoor environment.

[0017] (5) When in use, for this energy storage cabinet, through the air cooling device and the liquid cooling device, when the liquid cooling device operates, the coolant flows back from the cooling plate to the liquid cooling main unit through the liquid inlet pipe. When the air cooling device is started, the electric fan rotates to drive the air to flow. When passing through the air permeable plate, it fully contacts the surface of the liquid inlet pipe to pre-cool the liquid in the pipe, reducing the temperature of the coolant when it flows back. This reduces the energy consumption required for the liquid cooling main unit to cool the coolant, reduces the working load of the liquid cooling main unit, and extends the service life of the liquid cooling main unit.

A side wall of the driving device 20 is fixedly connected with a side wall of the inner layer board 112. A side wall of the driving device 20 is fixedly connected with a cleaning device 30. The cleaning device 30 includes a rotating shaft 31. Two ends of the rotating shaft 31 are fixedly connected with sliders 32. A side wall of the inner layer board 112 is slidably connected with the sliders 32. A side wall of the rotating shaft 31 is fixedly connected with a rolling brush 33. A partition device 40 is slidably connected with a side wall of the inner layer board 112; the partition device 40 includes a sliding rod 41. A side wall of the sliding rod 41 is slidably connected with a side wall of the inner layer board 112. A top end of the sliding rod 41 is fixedly connected with a pushing plate 42. A bottom end of the sliding rod 41 is fixedly connected with an upper pressing plate 43. A connecting shaft 44 is fixedly connected with an inner wall of the limiting frame 113. A side wall of the connecting shaft 44 is rotatably connected with a partition plate 45. A torsion spring 46 is fixedly connected with a side wall of the connecting shaft 44. A side wall of the torsion spring 46 is fixedly connected with a bottom wall of the partition plate 45. A dust removal device 50 is fixedly connected with a side wall of the partition device 40; the dust removal device 50 includes a pressing device 51. A side wall of the pressing device 51 is fixedly connected with a compressed air plate 52. A gas storage box 53 is fixedly connected with a side wall of the inner layer board 112. A side wall of the compressed air plate 52 is slidably connected with an inner wall of the gas storage box 53. A return spring 54 is fixedly connected with an inner wall of the gas storage box 53. An air inlet head 55 and an air outlet head 56 are respectively fixedly connected with two side walls of the gas storage box 53. An air outlet device 57 is fixedly connected with a side wall of the outer layer board 111. A first one-way valve 58 is fixedly connected with an inner wall of the air inlet head 55. A second one-way valve 59 is fixedly connected with a side wall of the air outlet head 56; during use, the air-cooling device 12 can be started to dissipate heat from the cabinet body 10. Air passes through the ventilation filter screen 114 and enters the cabinet body 10 to perform air-cooling heat dissipation on the devices inside the cabinet body 10; the ventilation filter screen 114 is prone to dust accumulation after long-term use. The driving device 20 can be started to drive the rotating shaft 31 of the cleaning device 30 to move, drive the sliders 32 to slide on the inner layer board 112, and make the rolling brush 33 clean the ventilation filter screen 114;The dust brushed off falls on the partition plate 45. During the upward sliding of the slider 32, it will contact the push plate 42, push the push plate 42 to move upward, drive the sliding rod 41 and the upper pressure plate 43 to move upward. The upper pressure plate 43 presses the partition plate 45, and the partition plate 45 rotates around the connecting shaft 44 to compress the torsion spring 46, opening the ventilation channel. The dust falling on the partition plate 45 then drops and lands on the bottom wall of the dust collection channel formed among the limit frame 113, the partition plate 45, the inner layer plate 112 and the outer layer plate 111. During the downward sliding of the slider 32, the upper pressure plate 43 moves downward along with the sliding rod 41 and no longer exerts pressure on the partition plate 45. The torsion spring 46 gradually releases its elastic potential energy, pushing the partition plate 45 to rotate reversely around the connecting shaft 44 to reset, and the partition plate 45 returns to the horizontal state, closing the ventilation channel. During the downward sliding of the slider 32, the dust removal device 50 plays a role. The pressing device 51 drives the air pressing plate 52 to slide downward in the air storage box 53, compressing the return spring 54. The air in the air storage box 53 is discharged from the air outlet head 56 through the second one-way valve 59, forming an air flow through the air outlet device 57 to blow the dust on the bottom wall of the dust collection channel out of the cabinet, reducing the influence of dust accumulation on the ventilation and operation of the energy storage cabinet.

[0022] The pressing device 51 includes an abutting plate 511. The side wall on one side of the sliding rod 41 is fixedly connected to the abutting plate 511, and the side wall on the other side is fixedly connected to a lower pressure plate 512. The top end of the air pressing plate 52 is fixedly connected to a downward pressing rod 513. One end of the downward pressing rod 513 is fixedly connected to the side wall of the air pressing plate 52, and the other end penetrates through the side wall of the air storage box 53. When the slider 32 slides upward, it pushes the push plate 42, the sliding rod 41 and the upper pressure plate 43 to move upward. The upper pressure plate 43 presses the partition plate 45 to rotate and open the ventilation channel, and the dust drops into the dust collection channel. When the slider 32 slides downward, the torsion spring 46 pushes the partition plate 45 to reset and close the channel. At the same time, during the downward movement of the sliding rod 41, it will contact the abutting plate 511 and drive the abutting plate 511 to move downward. During the downward movement of the abutting plate 511, it will contact the downward pressing rod 513, pushing the downward pressing rod 513 and the air pressing plate 52 to slide downward in the air storage box 53, compressing the return spring 54. The air in the air storage box 53 is discharged from the air outlet head 56 through the second one-way valve 59, forming an air flow through the air outlet device 57 to blow the dust in the dust collection channel out of the cabinet. By the up and down sliding of the slider 32, the partition device 40 and the dust removal device 50 are linked. When the ventilation channel is opened, the dust naturally drops into the dust collection channel, and after the channel is closed, the dust is promptly discharged out of the cabinet by the air flow generated by compressed air, enabling both the inside and outside of the cabinet 10 to ventilate smoothly and realizing dust removal inside the energy storage cabinet.

[0023] The air outlet device 57 includes an air outlet frame 571, the side wall of the air outlet frame 571 is fixedly connected to the side wall of the outer plate 111, the side wall of the air outlet frame 571 is hinged with a cover plate 572, the side wall of the outer plate 111 is provided with an air outlet 573, the side wall of the air outlet frame 571 close to the cover plate 572 is inclined, and the cover plate 572 is attached to the side wall of the air outlet frame 571 under the action of gravity; when in use, the driving slide rod 41 drives the abutment plate 511 to move downward, and the abutment plate 511 pushes the lower pressure rod 513 and the air pressure plate 52 to slide downward in the air storage box 53, compressing the return spring 54, and the air in the air storage box 53 passes through the second one-way valve 59 is discharged from the air outlet head 56 into the air outlet frame 571; at this time, the airflow with a certain pressure hits the side wall of the inclined air outlet frame 571, and pushes open the cover plate 572 attached to the side wall under the action of gravity. The air forms an airflow through the air outlet 573, and blows the dust in the dust collection channel out of the cabinet. When the airflow stops, the cover plate 572 is re-attached to the side wall of the air outlet frame 571 under the action of gravity, which can prevent external rainwater, dust and other debris from entering the energy storage cabinet through the air outlet 573, so that the energy storage cabinet can achieve dust removal while ensuring good protection of the energy storage cabinet, so that the energy storage cabinet can operate stably in outdoor environments.

[0024] The driving device 20 includes a motor 21, the side wall of the motor 21 is fixedly connected to the side wall of the outer plate 111, the output end of the motor 21 is fixedly connected to the first gear 22, the side wall of the inner plate 112 is rotatably connected to the second gear 23, the first gear 22 is meshed with the second gear 23, the edge of the side wall of the second gear 23 is fixedly connected to the driving block 24, the side wall of the inner plate 112 is slidably connected to the connecting rod 25, one end of the connecting rod 25 is rotatably connected to the side wall of the rotating shaft 31, and the other end is fixedly connected to the driving frame 26, the inner wall of the driving frame 26 is connected to the driving block 24 The side wall of the inner plate 112 slides and fits in. When in use, the motor 21 starts to drive the first gear 22 to rotate, and drives the second gear 23 to rotate synchronously, and the driving block 24 at the edge of the second gear 23 performs a circular motion accordingly. The driving block 24 slides and fits in with the inner wall of the driving frame 26 during the movement, converting the circular motion into a linear reciprocating motion of the driving frame 26 and the connecting rod 25. The connecting rod 25 drives the rotating shaft 31 and the slider 32 to slide up and down along the side wall of the inner plate 112, so that the roller brush 33 cleans the ventilation filter 114, realizing automatic cleaning of the ventilation filter 114.

[0025] On the side wall of the rotating shaft 31, third gears 34 are symmetrically and fixedly connected. On the side wall of the outer layer plate 111 close to the inner layer plate 112, a rack 35 is fixedly connected. The third gears 34 are meshed with the rack 35. When the driving device 20 drives the slider 32 to slide up and down along the side wall of the inner layer plate 112, the rotating shaft 31 fixedly connected to the slider 32 moves synchronously. At this time, the third gears 34 on the side wall of the rotating shaft 31 roll on the rack 35 fixed to the outer layer plate 111. Since the third gears 34 are meshed with the rack 35, this rolling motion causes the rotating shaft 31 to rotate while moving up and down. The rotation of the rotating shaft 31 drives the brush roller 33 to rotate synchronously, so that the brush roller 33 adds a rotating cleaning action during the process of reciprocating cleaning the ventilation filter screen 114 up and down, enhancing the cleaning effect on the ventilation filter screen 114.

[0026] Embodiment 2: Please refer to Figure 1 - Figure 6 , the present invention provides a technical solution: on the basis of Embodiment 1, a rain shield 115 is fixedly connected to the side wall of the outer layer plate 111. The air cooling device 12 includes a top cover 121. At the bottom of the side wall of the top cover 121, a ventilation plate 122 is fixedly connected. On the side wall of the inner layer plate 112, a mounting plate 123 is fixedly connected. On the side wall of the mounting plate 123, an electric fan 124 is fixedly connected. During use, the electric fan 124 is powered on and starts to generate an air flow. The air passes through the ventilation filter screen 114 and enters the cabinet 10, exchanges heat with the internal energy storage device inside, takes away the heat generated by the operation of the device, and then is discharged outside the cabinet through the ventilation plate 122. The air flow is accelerated under the action of the electric fan 124, improving the cooling effect. Moreover, the structural design of the top cover 121 and the ventilation plate 122 can block external rainwater and sundries from entering the cabinet while realizing ventilation and heat dissipation, providing good heat dissipation and protection conditions for the energy storage cabinet in the outdoor environment and ensuring its stable and efficient operation.

[0027] A mounting frame 13 is fixedly connected to the side wall of the cabinet panel 11, and a liquid cooling device 14 is fixedly connected to the side wall of the mounting frame 13. The liquid cooling device 14 includes a liquid cooling host 141, the side wall of the liquid cooling host 141 is fixedly connected to the side wall of the mounting frame 13, a cooling plate 142 is fixedly connected to the side wall of the mounting frame 13, an outlet pipe 143 and an inlet pipe 144 are fixedly connected to the side wall of the liquid cooling host 141, the side wall of the cooling plate 142 is fixedly connected to the outlet pipe 143, and the side wall of the cooling plate 142 is fixedly connected to the side wall of the inlet pipe 144. When in use, the liquid cooling host 141 is started, and the coolant in the liquid cooling host 141 flows into the cooling plate 142 through the outlet pipe 143. When the coolant flows in the cooling plate 142, it absorbs the heat dissipated by the energy storage device inside the cabinet 10 through heat exchange. The heated coolant then flows back into the liquid cooling host 141 through the inlet pipe 144. After the cooling treatment is completed in the liquid cooling host 141, it circulates back into the cooling plate 142 through the outlet pipe 143 again. The liquid cooling device 14 realizes the heat dissipation of the energy storage device through the circulating flow of the coolant. The liquid cooling device 14 and the air cooling device 12 cooperate with each other to form a dual heat dissipation guarantee, further improving the stability of the energy storage cabinet during operation in outdoor complex environments.

[0028] A ventilation plate 145 is fixedly connected to the top end of the mounting frame 13, and the side wall of the inlet pipe 144 is fixedly connected to the side wall of the ventilation plate 145. When the liquid cooling device 14 is operating, the coolant flows back from the cooling plate 142 to the liquid cooling host 141 through the inlet pipe 144. Since the inlet pipe 144 is fixedly connected to the ventilation plate 145, the ventilation plate 145 can allow a small amount of gas generated by heat in the coolant to escape, preventing the gas from accumulating in the inlet pipe 144 and the liquid cooling host 141 to form air resistance. When the air cooling device 12 is started, the electric fan 124 rotates to drive the air to flow. When passing through the ventilation plate 145, it comes into full contact with the surface of the inlet pipe 144 to pre-cool the liquid in the pipe, reducing the temperature of the coolant when it flows back. This enables the liquid cooling host 141 to consume less energy when cooling the coolant, reducing the working load of the liquid cooling host 141 and extending the service life of the liquid cooling host 141.

[0029] Working principle: When in use, this kind of liquid-cooled energy storage cabinet for outdoor use mainly consists of a cabinet 10, a driving device 20, a cleaning device 30, a partition device 40, and a dust removal device 50. The driving device 20 is used to drive the cleaning device 30 to clean the ventilation part of the cabinet 10, and the partition device 40 is used to accumulate dust in a fixed position and clean the dust outside the cabinet 10 through the dust removal device 50.

[0030] Among them, the cabinet 10 includes a cabinet panel 11, an air cooling device 12, a mounting frame 13, and a liquid cooling device 14. When in use, the air cooling device 12 and the liquid cooling device 14 are started to dissipate heat from the cabinet 10, and the mounting frame 13 is used to support the liquid cooling device 14.

[0031] The cabinet board 11 includes an outer layer board 111, an inner layer board 112, a limit frame 113, a ventilation filter screen 114, and a rain shield 115; during use, with its outwardly convex arc structure, the rain shield 115 quickly diverts the falling rainwater to the outside of the cabinet body 10, effectively preventing the rainwater from directly impacting the ventilation filter screen 114; driven by the air cooling device 12, the outside air flows in through the ventilation opening reserved at the bottom of the rain shield 115, and is first preliminarily filtered by the ventilation filter screen 114 to intercept sundries such as dust and insects. The clean air then passes through the limit frame 113 and enters the interior of the cabinet body 10, providing a heat dissipation air flow channel for the energy storage device.

[0032] The air cooling device 12 includes a top cover 121, a ventilation board 122, a mounting board 123, and an electric fan 124; during use, when the electric fan 124 is powered on and starts, it generates an air flow; the air passes through the ventilation filter screen 114 and enters the cabinet body 10, exchanges heat with the internal energy storage device, takes away the heat generated by the operation of the device, and then is discharged outside the cabinet through the ventilation board 122; the air is accelerated in the flow by the electric fan 124, improving the cooling effect; moreover, the structural design of the top cover 121 and the ventilation board 122 can block the outside rainwater and sundries from entering the cabinet while realizing ventilation and heat dissipation, providing good heat dissipation and protection conditions for the energy storage cabinet in the outdoor environment and ensuring its stable and efficient operation.

[0033] The liquid cooling device 14 includes a liquid cooling main unit 141, a cooling plate 142, an outlet pipe 143, an inlet pipe 144, and a breathable plate 145; during use, when the liquid cooling main unit 141 is started, the coolant in the liquid cooling main unit 141 flows into the cooling plate 142 through the outlet pipe 143. When the coolant flows in the cooling plate 142, it absorbs the heat dissipated by the energy storage device inside the cabinet body 10 through heat exchange. The heated coolant then flows back through the inlet pipe 144. After the air cooling device 12 is started, when the electric fan 124 rotates to drive the air flow and passes through the breathable plate 145, it comes into full contact with the surface of the inlet pipe 144 to pre-cool the liquid in the pipe, and then the liquid flows back to the liquid cooling main unit 141. After the liquid is cooled in the liquid cooling main unit 141, it circulates back into the cooling plate 142 through the outlet pipe 143 again; the liquid cooling device 14 realizes the heat dissipation of the energy storage device through the circulating flow of the coolant, which reduces the energy consumption required for the liquid cooling main unit 141 to cool the coolant, reduces the working load of the liquid cooling main unit 141, and extends the service life of the liquid cooling main unit 141.

[0034] The driving device 20 includes a motor 21, a first gear 22, a second gear 23, a driving block 24, a connecting rod 25, and a driving frame 26; during use, the motor 21 starts to drive the first gear 22 to rotate, and drives the second gear 23 to rotate synchronously. The driving block 24 at the edge of the second gear 23 then makes a circular motion; during the movement of the driving block 24, it slides and fits with the inner wall of the driving frame 26, converting the circular motion into a linear reciprocating motion of the driving frame 26 and the connecting rod 25; the connecting rod 25 drives the rotating shaft 31 and the slider 32 to slide up and down along the side wall of the inner layer plate 112, so that the roller brush 33 cleans the ventilation filter screen 114; realizing the automatic cleaning of the ventilation filter screen 114.

[0035] The cleaning device 30 includes a rotating shaft 31, a slider 32, a roller brush 33, a third gear 34, and a rack 35; when the driving device 20 drives the slider 32 to slide up and down along the side wall of the inner layer plate 112, the rotating shaft 31 fixedly connected to the slider 32 moves synchronously. At this time, the third gear 34 on the side wall of the rotating shaft 31 rolls on the rack 35 fixed to the outer layer plate 111; due to the meshing of the third gear 34 and the rack 35, this rolling motion causes the rotating shaft 31 to rotate while moving up and down. The rotation of the rotating shaft 31 drives the roller brush 33 to rotate synchronously, so that the roller brush 33 adds a rotational cleaning action during the process of reciprocating up and down cleaning of the ventilation filter screen 114, enhancing the cleaning effect on the ventilation filter screen 114.

[0036] The partition device 40 includes a slide rod 41, a push plate 42, an upper pressure plate 43, a connecting shaft 44, a partition plate 45, and a torsion spring 46; during use, when the slider 32 of the cleaning device 30 slides upward, it will contact the push plate 42 and apply a thrust force. The push plate 42 drives the slide rod 41 to move upward synchronously, and further causes the upper pressure plate 43 fixed to the bottom end of the slide rod 41 to squeeze the partition plate 45 upward; the partition plate 45 rotates with the connecting shaft 44 as the fulcrum. During this process, the torsion spring 46 is compressed, and the partition plate 45 that originally horizontally closes the ventilation channel tilts and opens, so that the dust brushed off by the cleaning device 30 and accumulated on the partition plate 45 falls into the dust collection channel under the action of gravity; when the slider 32 finishes moving upward and starts to slide downward, the upper pressure plate 43 no longer applies force to the partition plate 45, and the torsion spring 46 gradually releases the stored elastic potential energy, driving the partition plate 45 to rotate reversely around the connecting shaft 44 and reset to its original horizontal state, closing the ventilation channel again to prevent the airflow from blowing the dust back to the ventilation filter screen 114 when the subsequent dust removal device 50 works, ensuring the cleanliness and stability of the airflow path inside the cabinet 10.

[0037] The dust removal device 50 includes a pressing-down device 51, a compressed air plate 52, an air storage box 53, a return spring 54, an air inlet head 55, an air outlet head 56, an air outlet device 57, a first one-way valve 58, and a second one-way valve 59. When in use, during the downward sliding of the slider 32, the dust removal device 50 comes into play. The pressing-down device 51 drives the compressed air plate 52 to slide downward in the air storage box 53, compressing the return spring 54. The air in the air storage box 53 is discharged from the air outlet head 56 through the second one-way valve 59, and an air flow is formed through the air outlet device 57 to blow the dust on the inner bottom wall of the dust collection channel out of the cabinet, reducing the influence of dust accumulation on the ventilation and operation of the energy storage cabinet.

[0038] The pressing-down device 51 includes a contact plate 511, a lower pressing plate 512, and a pressing-down rod 513. During the downward movement of the sliding rod 41, it will contact the contact plate 511 and drive the contact plate 511 to move downward. During the downward movement of the contact plate 511, it will contact the pressing-down rod 513, pushing the pressing-down rod 513 and the compressed air plate 52 to slide downward in the air storage box 53, compressing the return spring 54. The air in the air storage box 53 is discharged from the air outlet head 56 through the second one-way valve 59, and an air flow is formed through the air outlet device 57 to blow the dust in the dust collection channel out of the cabinet. Through the up-and-down sliding of the slider 32, the partition device 40 and the dust removal device 50 are linked. When the ventilation duct is opened, the dust drops into the dust collection channel, and after the channel is closed, the air flow generated by the compressed air is used in time to blow the dust out of the cabinet, enabling both the inside and outside of the cabinet body 10 to have smooth ventilation and realizing dust removal inside the energy storage cabinet.

[0039] The air outlet device 57 includes an air outlet frame 571, a cover plate 572, and an air outlet 573. When in use, driving the sliding rod 41 drives the contact plate 511 to move downward. The contact plate 511 pushes the pressing-down rod 513 and the compressed air plate 52 to slide downward in the air storage box 53, compressing the return spring 54. The air in the air storage box 53 is discharged from the air outlet head 56 through the second one-way valve 59 and enters the air outlet frame 571. At this time, the air flow with a certain pressure impacts the side wall of the inclined air outlet frame 571, pushing open the cover plate 572 that fits on the side wall under the action of gravity. The air forms an air flow through the air outlet 573 to blow the dust in the dust collection channel out of the cabinet. When the air flow stops, the cover plate 572 fits on the side wall of the air outlet frame 571 again under the action of gravity, which can prevent external rainwater, dust and other sundries from entering the interior of the energy storage cabinet through the air outlet 573. While the energy storage cabinet realizes dust removal, it ensures good protection of the energy storage cabinet, enabling the energy storage cabinet to operate stably in the outdoor environment.
