Description

Technical Field

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

[0002] A liquid-cooled energy storage cabinet uses a liquid cooling system to dissipate heat and control the temperature of the energy storage batteries. The liquid cooling system primarily consists of a cooling plate, cooling pipes, a water inlet pipe, a water outlet pipe, and a cooling water tank. The cooling pipes are arranged in an S-shaped, circuitous pattern outside the cooling plate. Coolant circulates through the cooling pipes, absorbing heat generated by the battery modules and other equipment inside the cabinet. The coolant then flows back to the cooling water tank through the water inlet pipe, where it dissipates heat and re-enters the cooling pipes through the water outlet pipe, completing a complete cooling cycle.

[0003] When the temperature of the energy storage battery in the energy storage cabinet is high, the cooling water tank requires more energy to cool down and dissipate the heated liquid. To reduce this energy consumption, an air cooling system can be set up. While assisting the liquid cooling system in dissipating heat for the energy storage battery, it can also dissipate heat for the heated liquid, thereby reducing the energy consumption of the cooling water tank. However, the installation and use of the liquid-cooled energy storage integrated machine in outdoor occasions places higher requirements on outdoor protection conditions, requiring it to have the functions of waterproofing, dustproofing, and preventing the entry of foreign objects. However, during the operation of the equipment, the air cooling system needs to maintain ventilation to dissipate heat internally.

[0013] The present invention provides a liquid-cooled energy storage cabinet for outdoor use. It has the following beneficial effects:

[0014] (1) The energy storage cabinet, through the drive device and the cleaning device, when in use, the motor starts to drive the first gear to rotate, and drives the second gear to rotate synchronously, and the drive block at the edge of the second gear performs a circular motion accordingly; during the movement, the drive block slides and fits against the inner wall of the drive frame, converting the circular motion into a linear reciprocating motion of the drive 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 plate, so that the roller brush cleans the ventilation filter, thereby realizing automatic cleaning of the ventilation filter.

[0015] (2) When the energy storage cabinet is in use, the driving device is started to drive the slider to slide downward. The downward pressure 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, thereby reducing the impact of dust accumulation on the ventilation and operation of the energy storage cabinet.

[0016] (3) The energy storage cabinet, through the partition device, when in use, when the slider of the cleaning device slides upward, it will contact the push plate and apply a thrust, and the push plate drives the slide rod to move upward synchronously, thereby causing the upper pressure plate fixed at the bottom end of the slide rod to squeeze the partition upward; the partition rotates with the connecting shaft as the fulcrum, and in this process, the torque spring is compressed, and the partition that originally closed the ventilation channel horizontally is tilted and opened, so that the dust brushed off and accumulated on the partition by the cleaning device falls into the dust collection channel under the action of gravity; when the slider completes the upward movement and starts to slide downward, the upper pressure plate no longer applies force to the partition, and the torque spring gradually releases the stored elastic potential energy, driving the partition to rotate in the opposite direction around the connecting shaft and reset, and restore to a horizontal state, closing the ventilation channel, preventing the air flow from blowing dust back to the ventilation filter when the subsequent dust removal device is working, and ensuring the cleanliness and stability of the air flow path inside the cabinet.

[0017] (IV) The energy storage cabinet drives the sliding rod to move the abutment plate downward through the air outlet device. The abutment plate pushes the lower pressure 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 into the air outlet frame. At this time, the airflow with a certain pressure hits the inclined side wall of the air outlet frame, pushing open the cover plate attached to the side wall under the action of gravity. The air forms an airflow through the air outlet, blowing the dust in the dust collection channel out of the cabinet. When the airflow stops, the cover plate re-attaches to the side wall of the air outlet frame under the action of gravity, which can prevent external rain, dust and other debris from entering the energy storage cabinet through the air outlet. The energy storage cabinet can achieve dust removal while ensuring good protection, so that the energy storage cabinet can operate stably in outdoor environments.

[0018] (5) This energy storage cabinet utilizes both air and liquid cooling. When the liquid cooling system is in operation, the coolant flows from the cooling plate through the liquid inlet pipe back to the liquid-cooled mainframe. When the air cooling system is activated, the electric fan drives the air, which, as it passes through the air permeable plate, comes into contact with the surface of the liquid inlet pipe, pre-dissipating heat from the liquid within the pipe and lowering the temperature of the coolant as it returns. This reduces the energy consumed by the liquid-cooled mainframe to cool the coolant, alleviating its workload and extending its service life. BRIEF DESCRIPTION OF THE DRAWINGS

[0037] The side wall of the rotating shaft 31 is symmetrically fixedly connected with a third gear 34, and the side wall of the outer plate 111 near the inner plate 112 is fixedly connected with a rack 35, and the third gear 34 and the rack 35 are meshed with each other; when the driving device 20 drives the slider 32 to slide up and down along the side wall of the inner plate 112, the rotating shaft 31 fixedly connected to the slider 32 moves synchronously, and 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 plate 111; because the third gear 34 is meshed with the rack 35, this rolling motion causes the rotating shaft 31 to rotate while moving up and down, and the rotation of the rotating shaft 31 drives the roller brush 33 to rotate synchronously, so that the roller brush 33 adds a rotating cleaning action in the process of reciprocating cleaning of the ventilation filter 114 up and down, thereby enhancing the cleaning effect of the ventilation filter 114.

[0038] Example 2: Please refer to Figure 1 - Figure 6 , the present invention provides a technical solution: on the basis of embodiment 1, the side wall of the outer plate 111 is fixedly connected with a rainproof cover 115, the air cooling device 12 includes a top cover 121, the bottom of the side wall of the top cover 121 is fixedly connected with a ventilation plate 122, the side wall of the inner plate 112 is fixedly connected with a mounting plate 123, and the side wall of the mounting plate 123 is fixedly connected with an electric fan 124; when in use, the electric fan 124 is powered on to generate airflow; the air passes through the ventilation filter 114 into the cabinet 10, exchanges heat with the internal energy storage device, takes away the heat generated by the operation of the equipment, and then is discharged outside the cabinet through the ventilation plate 122; the air is accelerated by the action of the electric fan 124 to improve the cooling effect; and the structural design of the top cover 121 and the ventilation plate 122 can prevent external rainwater and debris from entering the cabinet on the basis of achieving ventilation and heat dissipation, thereby providing good heat dissipation and protection conditions for the energy storage cabinet in outdoor environments, ensuring its stable and efficient operation.

[0039] The side wall of the cabinet panel 11 is fixedly connected to the mounting bracket 13, and the side wall of the mounting bracket 13 is fixedly connected to the liquid cooling device 14. 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 bracket 13. The side wall of the mounting bracket 13 is fixedly connected to a cooling plate 142. The side wall of the liquid cooling host 141 is fixedly connected to a liquid outlet pipe 143 and a liquid inlet pipe 144. The side wall of the cooling plate 142 is fixedly connected to the liquid outlet pipe 143, and the side wall of the cooling plate 142 is fixedly connected to the side wall of the liquid inlet pipe 144. During use, the liquid-cooled main unit 141 is started, and the coolant in the liquid-cooled main unit 141 flows into the cooling plate 142 through the liquid outlet pipe 143. When the coolant flows in the cooling plate 142, it absorbs the heat emitted by the energy storage device inside the cabinet 10 through heat exchange. The heated coolant then flows back to the liquid-cooled main unit 141 through the liquid inlet pipe 144. After the cooling process is completed in the liquid-cooled main unit 141, it circulates again through the liquid outlet pipe 143 and flows into the cooling plate 142.

[0040] A ventilation plate 145 is fixedly connected to the top of the mounting frame 13, and the side wall of the liquid inlet pipe 144 is fixedly connected to the side wall of the ventilation plate 145. When the liquid cooling device 14 is in operation, the coolant flows from the cooling plate 142 through the liquid inlet pipe 144 back to the liquid cooling host 141. Since the liquid inlet pipe 144 is fixedly connected to the ventilation plate 145, the ventilation plate 145 allows a small amount of gas generated by heat in the coolant to be discharged, thereby preventing the gas from accumulating in the liquid inlet pipe 144 and the liquid cooling host 141 to form air blockage. When the air cooling device 12 is started, the electric fan 124 is turned on to drive the air flow. When passing through the ventilation plate 145, the air is fully contacted with the surface of the liquid inlet pipe 144, pre-dissipating the heat of the liquid in the pipe and reducing the temperature of the coolant when it returns. This reduces the energy consumed by the liquid cooling host 141 when cooling the coolant, reduces the workload of the liquid cooling host 141, and extends the service life of the liquid cooling host 141.

The partition device 40 is used to accumulate dust in a fixed position and clean the dust to the outside of the cabinet body 10 through the dust removal device 50.

[0043] 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 .

[0044] The cabinet panel 11 includes an outer panel 111, an inner panel 112, a limiting frame 113, a ventilation filter 114, and a rain cover 115; when in use, the rain cover 115, with its outwardly protruding arc structure, quickly guides the falling rainwater to the outside of the cabinet body 10, effectively preventing the rainwater from directly impacting the ventilation filter 114; driven by the air cooling device 12, the outside air flows in through the vents reserved at the bottom of the rain cover 115, and is first preliminarily filtered by the ventilation filter 114 to intercept dust, insects and other debris. The clean air then passes through the limiting frame 113 into the interior of the cabinet body 10, providing a heat dissipation airflow channel for the energy storage equipment.

[0045] The air cooling device 12 includes a top cover 121, a ventilation plate 122, a mounting plate 123, and an electric fan 124; when in use, the electric fan 124 is powered on and started to generate airflow; the air passes through the ventilation filter 114 into the cabinet 10, exchanges heat with the internal energy storage equipment, takes away the heat generated by the operation of the equipment, and is then discharged out of the cabinet through the ventilation plate 122; the air flows faster under the action of the electric fan 124, thereby improving the cooling effect; and the structural design of the top cover 121 and the ventilation plate 122 can prevent external rain and debris from entering the cabinet on the basis of achieving ventilation and heat dissipation, thereby providing good heat dissipation and protection conditions for the energy storage cabinet in outdoor environments, ensuring its stable and efficient operation.

[0046] The liquid cooling device 14 includes a liquid cooling host 141, a cooling plate 142, a liquid outlet pipe 143, a liquid inlet pipe 144, and a ventilation plate 145. 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 liquid outlet pipe 143. When the coolant flows in the cooling plate 142, it absorbs the heat emitted by the energy storage device inside the cabinet 10 through heat exchange. The heated coolant then flows through the liquid inlet pipe 144. After the air cooling device 12 is started, the electric fan 124 drives the air to flow through the ventilation plate 145. 5, it is in full contact with the surface of the liquid inlet pipe 144, and after pre-heat treatment of the liquid in the pipe, the liquid flows back to the liquid-cooled host 141. After the liquid is cooled in the liquid-cooled host 141, it circulates again through the liquid outlet pipe 143 and flows into the cooling plate 142; the liquid cooling device 14 realizes heat dissipation of the energy storage device through the circulation of the coolant, which reduces the energy consumed by the liquid-cooled host 141 when cooling the coolant, reduces the workload of the liquid-cooled host 141, and extends the service life of the liquid-cooled host 141.

[0047] 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; 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; during the movement, the driving block 24 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 114, thereby realizing automatic cleaning of the ventilation filter 114.

[0048] 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 plate 112, the rotating shaft 31 fixedly connected to the slider 32 moves synchronously, and 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 plate 111; since the third gear 34 is engaged with the rack 35, this rolling motion causes the rotating shaft 31 to rotate while moving up and down, and the rotation of the rotating shaft 31 drives the roller brush 33 to rotate synchronously, so that the roller brush 33 adds a rotating cleaning action in the process of reciprocating up and down cleaning of the ventilation filter 114, thereby enhancing the cleaning effect of the ventilation filter 114.

[0049] The partition device 40 includes a slide bar 41, a push plate 42, an upper pressure plate 43, a connecting shaft 44, a partition plate 45, and a torque spring 46. When in use, when the slider 32 of the cleaning device 30 slides upward, it contacts the push plate 42 and applies a thrust, and the push plate 42 drives the slide bar 41 to move upward synchronously, thereby causing the upper pressure plate 43 fixed at the bottom end of the slide bar 41 to press the partition plate 45 upward; the partition plate 45 rotates with the connecting shaft 44 as a fulcrum, and in this process, the torque spring 46 is compressed, and the partition plate 45, which originally closed the ventilation channel horizontally, tilts open, The dust brushed off by the cleaning device 30 and accumulated on the partition 45 falls into the dust collection channel under the action of gravity; when the slider 32 completes the upward movement and starts to slide downward, the upper pressure plate 43 no longer applies force to the partition 45, and the torque spring 46 gradually releases the stored elastic potential energy, driving the partition 45 to rotate in the opposite direction around the connecting shaft 44 and reset, restoring the horizontal state, closing the ventilation channel, and preventing the airflow from blowing the dust back to the ventilation filter 114 when the subsequent dust removal device 50 is working, thereby ensuring the cleanliness and stability of the airflow path inside the cabinet 10.

[0050] The dust removal device 50 includes a downward pressure device 51, an air pressure 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, when the slider 32 slides downward, the dust removal device 50 comes into play, the downward pressure device 51 drives the air pressure 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 bottom wall of the dust collection channel out of the cabinet, thereby reducing the impact of dust accumulation on the ventilation and operation of the energy storage cabinet.

[0051] The downward pressure device 51 includes an abutment plate 511, a downward pressure plate 512, and a downward pressure rod 513; the sliding rod 41 will contact the abutment plate 511 during the downward movement, and drive the abutment plate 511 to move downward. The abutment plate 511 will contact the downward pressure rod 513 during the downward movement, pushing the downward 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 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. The slider 32 slides up and down, and the partition device 40 and the dust removal device 50 are linked. When the ventilation duct is opened, the dust falls into the dust collection channel. After the channel is closed, the air flow generated by the compressed air is used in time to discharge the dust out of the cabinet, so that the inside and outside of the cabinet body 10 can be ventilated smoothly, and dust removal can be achieved in the energy storage cabinet.

[0052] The air outlet device 57 includes an air outlet frame 571, a cover plate 572, and an air outlet 573. 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. The air in the air storage box 53 is discharged from the air outlet head 56 through the second one-way valve 59 and into the air outlet frame 571. At this time, the air with a certain pressure hits the side wall of the inclined air outlet frame 571, Under the action of gravity, the cover plate 572 attached to the side wall is pushed open, and air forms an airflow through the air outlet 573, blowing 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 rain, dust and other debris from entering the energy storage cabinet through the air outlet 573. This ensures that the energy storage cabinet has good protection while achieving dust removal, allowing the energy storage cabinet to operate stably in outdoor environments.
